0 | unity 5 how to get a shadowmap I'm writing a custom shader in unity 5 that requires a shadowmap (not just for drawing shadows but also for different computations involving scattering particles through fog). Does anybody know how to actually get the shadow map in unity rather than just using the fallback option? That is including the actual Z buffer not just the resulting 1's and 0's. I could also use the depth buffer from the camera but that only appears to apply to camera used by the player rather than the second one I can add to replace the light (inside the light). |
0 | Display hide image with zoom in out After spending a while looking through the forums, I haven't been able to find a thread that deals with transforms on an image. Essentially, what I'm trying to do is display and hide an image at the start of a level in a game I'm working on. The image should start out large and with 100 transparency, then shrink to a certain size within the camera bounds with no transparency, idle for a second, then fade back out the way it came. How would this be done programmatically? Thanks in advance! |
0 | Unity sprites and layouts I am trying to learn Unity for a simple board game. The question is, is it possible to use grid layout group (or any layout component) with sprites? The goal is to fit a board into my view regardless of the aspect ratio of the device. The following grid should contain 7 by 7 sprites and it should scale up and down (no more then lets say 100 px) and have an aspect ratio of 1. I've tried adding a canvas and a panel that has a grid layout group component but it seems like sprites are not affected when added to the panel. Also it seems like when I try to work with a panel or a canvas they have a fixed sizes in units. Having fix sizes feels a little bit off. Is there a way to use layout components so sprites can have relative distances between them. So far I am stuck and lost in tutorials and feeling like the answer should not be this complicated. Any push to the right direction is welcome. |
0 | Importing audiofile into Unity3d gets shown after ending playmode I am working on a game where the user has the possibility to import custom audio tracks that can be listened to during the game. For this I am making use of System.IO.File.Copy method. This works, there are no issues or flaws here. When I inspect the target and destination folder the file(s) get copied properly and show up in the folder. The issue however is that the Unity Editor doesn't show the file despite it actually being there. During play mode in the Unity editor the new file isn't shown in the resources folder (which I use as destination for now). When I use windows file explorer I can clearly see the file in the corresponding folder. Using debugs (in Unity) also state that the folder is empty, however when I use debugs outside of Unity it shows that the folder contains the copied item. Keep in mind that these both debugs are called roughly at the same time. I have tested this in many ways to be 100 certain that Unity doesn't see the file, while it is there. So once I stop playmode it starts loading importing processing the new file and then it shows up in the folder in unity as well. When I launch playmode after this the file is indeed loaded and included in the game as well. I however need this to happen without having to stop playmode. So there is probably some type of processing that I haven't called for Unity to process the addition of the new file and for it to be visible. So in a nutshell basically copying a file from folder to folder isn't enough for Unity to directly utilized in the same play session (and all after). How can I make the audio file directly showable and accessable? There aren't any errors or warnings. The file plays correctly after it has been processed. I am at a loss with this issue bug. |
0 | How can I use Drag handlers (IBeginDragHandler, IEndDragHandler, IDragHandler) with a 2D sprite renderer instead of a UI Image? In my game, I assigned all of the blocks to be 2D sprites so that they could be easily converted into prefabs However, when designing the drag and drop scripts, I noticed that all of the drag and drop handlers such as IBeginDragHandler, IEndDragHandler, IDragHandler, etc. weren't working at all. I later noticed that these were intended to be used by UI Images. Now I am left wondering what I can do to make these 2D Sprites be usable by these functions for UI Images. Do I have any other options other than to start from scratch by making new UI Images? Here's the small amount of code needed to create a reproducible example Public class DragDrop MonoBehaviour, IBeginDragHandler, IEndDragHandler, IDragHandler SerializeField private Canvas canvas private CanvasGroup canvasGroup private RectTransform rectTransform private void Awake() rectTransform GetComponent lt RectTransform gt () canvasGroup GetComponent lt CanvasGroup gt () public void OnBeginDrag(PointerEventData eventData) canvasGroup.alpha 0.6f canvasGroup.blocksRaycasts false public void OnDrag(PointerEventData eventData) rectTransform.anchoredPosition eventData.delta canvas.scaleFactor public void OnEndDrag(PointerEventData eventData) canvasGroup.alpha 1f canvasGroup.blocksRaycasts true |
0 | Unity Load Lightmaps at Runtime I'm a bit of a novice to lighting, but I think what I want to do is possible, so please bear with me. Due to the nature of my game, I've taken an approach where a singular scene game is where all of the gameplay occurs. For each level, I'm arranging all the GameObjects and Terrain in a secondary scene (named testbed) to my liking. Once I've got it to my liking, I save that to a prefab, which in turn is saved to an AssetBundle. I also generate the lighting at this point, which I can see appear in my project under a Assets Scenes testbed folder. At runtime, a script in the game scene reads the appropriate AssetBundle, and then loads amp positions all of my objects and characters. Everything about this works, except for updating the lighting. My approach is to store references to the lighting textures that have been output into the aforementioned testbed folder via a ScriptableObject (after trying and failing to use the LightingData object that appearred in this same folder) Then, when I'm loading my level up into the game scene, this block is executed public void LoadLighting(LevelKey key) var data levelMap.metaData.Find(it gt it.key key) var directions data.lightData.directions var lights data.lightData.lights var lightmaps new LightmapData directions.Length for (int i 0 i lt directions.Length amp amp i lt lights.Length i ) var lightmapData new LightmapData() lightmapData.lightmapDir directions i lightmapData.lightmapColor lights i lightmaps i lightmapData LightmapSettings.lightmaps lightmaps Based on a lot of searching, this should cause something to happen, but I can't detect any change in the scene. Does what I'm trying make any sense? Should I just scrap this and make dozens of different scenes (which I'm trying to avoid) instead? Really any advice here is appreciated. |

0 | Configurable Joint, linear limit range I am working on a physics driven pressable button, but I cannot seem to tackle the minimum and maximum limits. This is the rig I have set up for the button (as it looks when pressed down). 2D view 3D view The idea is that the box collider is a trigger and the button (cylinder, mesh collider) is a rigidbody with configurable joint, locked and limited on a single axis. I am using configurable joint, as that's the only one that supports basic, linear restrictions. I have set up the configurable joint to restrict motion on a single axis, but the joint only allows single dimensional limit, that is applied to both directions. Screen capture of relevant configuration Basically, the opened Linear Limit section is the last property that has been changed for the joint anything else are defaults and irrelevant (at least I haven't found my solution in the properties below, mostly angular stuff). The limit of 0.2 units work, and the button can be pressed it only gets pressed until those 0.2 units and thats the expected behaviour. The unexpected is that sometimes the angle at which I hit the button, adds force to the button outwards from the box, and it moves 0.2 away from it, ending up like this Obviously, the specified limit of 0.2 units constrain the movement in both directions from the anchor, actually resulting in the range of 0.2 to 0.2 (relative to anchor). How, and is it even possible, to restrict the movement only in a single direction relative to anchor? |
0 | Making a scriptable dynamic Distance Joint in Unity I have 2 2D RigidBodies that are connected together using a Distance Joint 2D... I update the distance of said Distance Joint 2D (using a script) expecting the distance between the two RigidBodies to change, but nothing actually happens. I'm guessing this is to do with the Physics engine not updating the positions of the RigidBodies? |
0 | Strange issue with bool comparing ToString always false unity c I have another problem with my code that I can't fix Basically i have an enum called 'type' in my Item class, which tells me if the item is consumable, or equipment, etc. In the database script I have made, it sets the type for each item (5 in total). So basically I have an inventory UI, with 5 items (inc. 2x consumables, 3x Equip) After much debugging checking things, I've found that the boolean prior to "sortedItems.Add(i) " is always FALSE. But it shouldnt be, BOTH VALUES ARE THE SAME as per the console log. I have input a print() line to check whats going on because my items are'nt sorting by type when I expect them to. public void SortItemsByType(string type) sortedItems.Clear() foreach (Item i in allItems) print("is the following true or false" i.type.ToString() type) print("this is iToString " i.type.ToString()) print("and this is type " type) if (i.type.ToString() type) sortedItems.Add(i) and (please note the 3 print lines, here is their output in the console (sorry but the dumb IDE won't let me copy paste the console, here is image) Im still very much a noob to this, so I am sure there is something I have missed. But for the life of me i cannot figure out why that bool is always resulting in FALSE? Any help is massively appreciated. Thanks |
0 | Whats the least expensive way to play video in unity? Alright, Ive asked this various ways but my situation is I have several (over 100) objects that have screens that need to play animated videos on them. There does not need to be sound, but this is for VR so performance is an issue. So far, after trying render textures and video materials and seeing that fps dropped, Ive been using this script to flip through sets of pngs and put them in the diffuse slot of a material public class VideoPlayerRawImage MonoBehaviour public Texture frames public int framesPerSecond 60 public bool isEmissive false void Update() int index (int)(Time.time framesPerSecond) frames.Length this.GetComponent lt Renderer gt ().material.mainTexture frames index if(isEmissive) this.GetComponent lt Renderer gt ().material.SetTexture(" EmissionMap", frames index ) if(index gt frames.Length 1) index 0 Is this the most efficient way to play videos? What would be a drawback to this method is there a better way? |
0 | How can I use shaders in Unity to write a scientific computing program? I want to write a GPU shallow water code on Unity3D. For sure, performance matters a lot. I've done this before using DirectX and C . But for a couple of reasons I want to redo it in Unity3D. I have some hands on experiences with Unity3D, but I have no idea how I can write GPGPU codes, like what I did in DirectX. In DirectX I am using textures as my data structure for the properties of water cells (height, x velocity, y velocity, etc.) and HLSL shaders as my parallel computational functions (kernels). Furthermore, I prefer my code to be near cross platform. Is it possible to do something similar in Unity3D using OpenGL? I am an engineer, and not a game developer, so please keep it simple ... |
0 | Create a seemless grid based polygonal tileset The aesthetics I am going for is demonstrated by many simulation games such as Simcity. But I am looking at this particular example Polygonal Planet Project by Oskar St lberg. I understand the concept when the player places or upgrades a tile, the game looks at adjacent tiles to figure out which tile should be used. And in most cases, a tile would be self contained, so I just need to design all possible variant of such tile. And I have some experience on procedural generation in 3D, so coding isn't the main problem for me. What I am wondering, are Does this type of continuous 3D tilesets have a name? I tried to google some examples tutorials but failed to find the appropriate keyword. Are there tools to make the process of creating tile variants easier? Is there a preferable process to create such tileset? Do I start by creating structures then divide them into repeatable patterns, or should I start with basic tiles and find way to create smooth transition between them? That's probably too much to answer in detail, but I would like some pointers on this topic (more about asset design than programming I suppose). Thx! |
0 | Having trouble combining clampMagnitude and some explosion force I have a character that uses rigidbody, and I am using AddForce() to make it move. And so I do rb.velocity Vector3.ClampMagnitude(rb.velocity, maxSpeed) to limit diagonal speed. Yes that did worked but my problem is adding for example explosion force. So if explosion force is very high, it will still clamp the velocity of the player. What way should I use to combine movement that limits diagonal speed and a properly working explosion force toward the player. At least give a clue how can I do it? My only main problem here is the way that I implemented to limit diagonal movement. I wanna improve that by not using Vector3.ClampMagnitude() so the AddExplosionForce() will work properly to the player. Because clamping magnitude of the player will also limit the velocity when it is affected by the explosion force. So can anyone give a clue how can I implement to limit diagonal movement without using clamp magnitude? I thought about normalizing the move like Vector3 move transform.right x transform.forward z move move.normalized Time.deltaTime moveSpeed But I realized I am using AddForce(). Even though I limited the diagonal speed, it will go faster and faster because there is no maxSpeed. Help please. |

0 | Advice on Story Text Based Game I am currently in preparation on making a game. This game will be looks like Lifeline by 3 Minute Games, which is a story text based game. My game will have the same concept with it. Where there will be a scrollable history of conversation between player and characters in game. However, my game will has more than one conversation history. He will be able to interact with more than one character. Therefore, when the game start, it will show list of interactable characters in game, and player can choose who he will interact with when any available. I am planning to make it with Unity. But I don't know is it possible to create some scrollable history of text, each with different content, like chat history, in Unity. So I wanna ask your opinion, is it good to just continue with using Unity, or should I change the game engine I use? If I should change, what is the best game engine to cope with this kind of game? Thank in advance ) |
0 | Box collider pushes me out of it's area slowly, I can pass through it if moving quickly I am new to Unity. I Setup a character in unity2D with a rigidbody. I had the scale off my sprites set to 100 pixels per unit. At this scale, my rigidbody character stood on top of platforms and could not pass through walls containing box colliders. I decided, that to make things easier, I would change all sprites to 1 pixel per unit. After doing so, I scaled everything (variables, sizes, etc.) by 100. I confirmed that the box colliders on both the caharcters, floor, and walls, are all in the same places, relatively. The box colliders on the floors still work, but the wall box colliders behave differently. When I walk into a wall, the wall slowly pushes me in a direction (depending on whether or not my character has walked through half the wall or not). The wall should be stopping my motion completely. The code is very simple, but this is what I use to move if (Input.GetKey (KeyCode.D)) transform.Translate (Vector2.right moveOffset Time.deltaTime) transform.localScale new Vector3(1,1,1) anim.SetBool("moving",true) Do note that the moveOffset variable, was scaled by 100 after the change. Thanks in advanced! |
0 | How to make rhythm game long notes in Unity? I'm making a rhythm game for a university course and I can't figure out a way to make the long sustained notes. For reference, this is what I mean taken from Guitar Hero I already have a system working for regular notes. The way I do it is that the notes are stored in an external file as numbers which represent the absence or presence of a note as well as what type of note it is, separated into musical bars 000 010 020 001 There are three lanes for the notes to be, and this means that in this particular bar there are notes wherever it's not 0 (with the numbers being different types of notes). I had thought of using this system to create long sustained note start and end markers (say 3 and 4) and that create another game object which would be the line between the start and end markers. But the way my note generator works is that the notes are not all generated at once because that'd be pretty heavy. Instead, the notes are generated at a certain time taking into account its speed so that it's instantiated and will reach the player's activator when it's supposed to. The following is a part of my note generator code, put in the Update method if current song time time offset is greater than time taken for all executed bars so far spawn the next bar's notes if (songTimer timeOffset gt (barExecutedTime barTime)) StartCoroutine(PlaceBar(noteData.bars barCount )) barExecutedTime barTime And here is the PlaceBar coroutine go through all notes in a bar creates an instance of note prefab depending on which note is meant to be spawned private IEnumerator PlaceBar(List lt SongParser.Notes gt bar) for (int i 0 i lt bar.Count i ) if (IsThereNote(bar i .bottom)) GameObject obj (GameObject) Instantiate(GetNotePrefab(bar i .bottom, true), new Vector3(bottomLane.transform.position.x distance, bottomLane.transform.position.y, bottomLane.transform.position.z 0.3f), Quaternion.identity) if (bar i .middle ! 0) GameObject obj (GameObject) Instantiate(GetNotePrefab(bar i .middle, false), new Vector3(middleLane.transform.position.x distance, middleLane.transform.position.y, middleLane.transform.position.z 0.3f), Quaternion.identity) if (bar i .top ! 0) GameObject obj (GameObject) Instantiate(GetNotePrefab(bar i .top, true), new Vector3(topLane.transform.position.x distance, topLane.transform.position.y, topLane.transform.position.z 0.3f), Quaternion.identity) yield return new WaitForSeconds((barTime bar.Count) Time.deltaTime) So if I were to make start and end markers, the start marker would not know where the end marker is because it doesn't exist. Could anyone help please? |

0 | Why does my collider behave strangely after a coroutine So I'm trying to create a simple script that is going to handle the logic for cutting down a tree I'm experiencing some strange behaviour with my script. I have a private field which holds the quot HP quot for the tree which starts at 100, and when I hit the tree it goes down by 25 every time, so I need to hit it four times in order for me to cut it down. Once the tree reaches lt 0 in terms of HP it should play an animation which simulates the tree being cut down, wait a couple of seconds and then play another animation of it appearing again. Most of this works fine, it's not until after the animation, where I start my CoRoutine to wait for a couple of seconds it starts messing up. ISSUE The first time I cut it down, it works fine.. However.. After it respawns I need to hit it like 4 5 times for it to go down to 50 health and then it works like normal. So I hit it once, it gets to 75, I hit it twice, still at 75, 3 times.. still at 75.. And eventually, it starts going to to 50, 25, 0 etc.. This only happens after I cut it down the first time, and the first time it works fine. Here is my Tree script NormalTree.cs public class NormalTree MonoBehaviour public static NormalTree instance private int health 100 public Animator animator private void Awake() if (instance null) instance this animator GetComponent lt Animator gt () private void Update() if (health lt 0) KillTree() private void KillTree() StartCoroutine(TreeSleep()) IEnumerator TreeSleep() animator.SetBool( quot treedead quot , true) gameObject.tag quot DeadTree quot yield return new WaitForSeconds(3f) animator.SetBool( quot treedead quot , false) gameObject.tag quot Tree quot health 100 public Item DamageTree(int damage) health damage Debug.Log( quot Tree health health quot ) if (health lt 0) return new Item Amount 1, ItemRarity Item.ItemRarityEnum.Gray, ItemType Item.ItemTypeEnum.Log else return null And in my PlayerController I have this, which essentially checks if my hitbox collides with an object that has the tag quot Tree quot private void OnTriggerEnter2D(Collider2D other) if (other.CompareTag( quot Tree quot )) var wc Skills.FirstOrDefault(x gt x.Name quot Woodcutting quot ) var tree other.GetComponent lt NormalTree gt ().DamageTree(25) if (tree ! null) inventory.AddItem(tree) wc.AddExperience(25) Debug.Log(wc.Level) |

0 | How to make an authoritative multiplayer game deterministic for all clients? I'm starting to create a multiplayer online game, with an authoritative server. As it is, the clients send inputs to the server which do the simulation and then send back to clients the updated state. The game is a top down shooter, so it's fast paced and input lags are not allowed here, so to avoid this I'm doing the simulation on the client too, and when the server update come back I compare the local simulation with the server response. If they are compatible everything is fine, otherwise, the client version is corrected. I was expecting that the client simulation desync at some point, because of all of the variables on physics, floating points, network etc... But this happens much more than I thought. Just by sending the inputs and simulating on the server, the results are very different, even on simple movements, like forwards and backwards on a clear space. Green is local, red is server response I need help on this step, a way of keeping, at least this kind of simple movement, consistent on the server and the clients. |
0 | Unity3D 3.5 pro Moving the camera vs setting draw distance I move the camera mostly via right click WASD, sometimes with shift if I want it to move faster. Occasionally, instead of moving my camera, it alters the draw distance FOV some visual aspect of the editing scene that causes trees and other object to disappear when I scroll enough, and eventually even the terrain starts disappearing. It is not m "zooming out". My camera does not move, the width and height of the FOV stays the same (one might say the depth is being altered though). What key am I hitting to cause this to happen, and is it possible to disable it? side note "keybinds" is probably the most spot on tag for this question but it doesn't exist (surprisingly) and I lack the rep to create it. |
0 | Convert a modified Transform.forward to world space I am trying to make an electricity system, where it is given the start and end points, and it works out a random sequence of points in the rough direction of the end point. These points are set as vertices on a line renderer, and it should end up joining up as a bolt of electricity. My problem is that it needs to move 'forward' from start to end. The easy solution is that the electricity comes from a game object, which is set to LookAt the end point. Then, every time it sets a 'nextPoint', it adds to the transform.forward. nextPoint new Vector3 ((startingPoint.forward.x divergence.x), (startingPoint.forward.y divergence.y), distance) divergence is a Vector3 containing a random increase on the x and y axis, and 1 on the z axis. This works, in a way. The problem is that it then assumes these are world space coordinates. So the line will go from starting point, to (eg. 0.3, 0.75, 1), and then back to the end point. I can't find a localToWorld conversion for a vector though, so I am not sure how to get the transform.forward whatever, converted from local to world space. |
0 | Using State Pattern with Unity I am new to Game Development and Unity. I have written a component for Jumping and Running, CharacterJumpAbility.cs and CharacterRunAbility.cs. I would like the Character to be able to Jump only if the Character is not moving. I came across a State Pattern but I can't understand how to apply it. For example if I want to Jump, first I must check if the Character is Running, but I have to do this in the CharacterJumpAbility.cs or in the CharacterController.cs (the component who handles inputs)? If I define a state for example public enum CharacterState Run, Jump For example if the player is pressing the space bar, I have to set the Jump state, the code that sets state CharacterState.Jump should be written in the CharacterJumpAbility.cs or in the component that handles inputs? And if I want to set a new state for example Jump, while I am running, this is clearly not possible, how to handle situations like these? |
0 | What is the Unity 2019.3.5 version of UnityEngine.UI.Text ? I was following a tutorial on how to create a dialogue Box in Unity, and in one part of the tutorial the tutor imports UnityEngine.UI and creates an object of type Text, but my version of Unity is 2019.3.5f1 and I learned through searching a bit online that this UnityEngine.UI doesn't exist anymore in this version, and that it was replaced with UnityEngine.UIElements, and this Text type doesn't exist anymore as well. I couldn't find a replacement for Text or what is the new nomenclature, nothing from trying stuff that popped in the auto complete or searching for answers in the Internet gave me answers. Maybe I just searched poorly, but if anyone happens to know, could you kindly answer? |
0 | Subclasses in unity editor I would like to implement an action system where gameobjects offer different actions available to characters. Actions are composed of several steps holding the details to be performed. These steps have different logic applied to them (go to location, play animation for a time, change variables), so I would like to have them as subclasses. However I would also like to be able to set up the actual data for an action in the UnityEditor. I know it is possible to do this using ScriptableObjects, but that requires creating an asset for each instance of a step, which I'd like to avoid, since only the classes get reused, the instances being pretty much unique to each gameobject. Is there a way to work with subclasses in the unityeditor without requiring a dedicated asset for each of the subclass instances cluttering up my folders? |

I am implementing a flight dynamics model using Unity's built in ECS package, Entities, and I keep running into one particular issue where the aircraft I'm trying to spawn gets converted into an entity twice.

0 | Endless 2d runner with increasing speed, how to adjust jump behavior? I am making an endless 2d runner with unity. my player object is not moving at all, i move all the other game objects. I have a SpeedManager script which increases the "speed" at every update by a short amount. The movement speed of every gameObject which is streaming towards the player is now multiplied with the SpeedManager "speed". One controll of my player is a jump. Currently i am using public Vector2 jumpForce new Vector2(0, 350) rigidbody2D.AddForce(jumpForce) The problem now is, as the game goes on, the game objects pass faster and faster but the player jump remains the same. What i want is a jump that goes as far as before, which means, the player should jump faster into the air, reach the same height and drop faster to the ground, so the jump distance is the same. I tried some stuff like multiplying both the jumpForce.y and the gravity of my player object with my SpeedManager.speed, but i did not achieve anything yet. ) Greetings. |

0 | Unity Transform Origin during Animation I have a sliding animation on this penguin model which moves the penguin from a standing position to a belly position. During this animation, I've noticed that the object transform origin stays locked relative to the animation, using the encoded origin from blender. In my case this is an undesired pivot point and is often buried beneath other game objects I may want to raycast against. Ideally, I am hoping to have the origin centered in the model with respect to the XZ plane throughout the animation. Toggling the handle position tool to quot Center quot in the editor gives me an origin that is closer to what I would like, however I understand this is just a feature of the editor and does not reflect the true object transform. My question for everyone is What are some ways I can achieve a transform that follows the body of my animation? I have parenting an empty game object, but this transform still would not follow the body animation. For raycasting below the body specifically, I am considering following the transform of my armature's spine which does follow the animation. Would this be a valid approach? Any help is much appreciated! |

0 | Art style for a character that has frequent visual changes during gameplay I'm creating a game with a bodybuilding fitness theme. The camera will almost always be focused on an inclined front view of a character who will be evolving very frequently during the game as the player 'levels up' the musculature of each part of the character such as arms, legs, chest, etc. I've been doing some research trying to figure out the most economical yet effective way to incorporate this visual mechanic of letting individual parts of a character independently increase in size and detail and have come up somewhat short, most likely due to my complete lack of experience when it comes to art (my experience is mostly in programming). I was thinking 2D would be best for this game, however maybe this one character should be in 3D? Would a low poly style fit these requirements, or should I look towards something akin to sprites or hand drawings? The games interactivity will be purely through menus so that doesn't need to be taken into account when dealing with the problem of this character. I would like this character to have some animations, of course, however I'm not sure if that fits the scope of this single question. |

I want the ocean to be a life like as possible but without compromising too much on rendering speeds. A Little more detail I am using Unity to create the game in and ultimately I will need to be able to release the game as a web player to there lies my limitations of the water simulation. For the actual simulation of the ocean I will need it to be able to react to the ships movement and vice versa. The end product of the simulation I want to be able to look like this simulation of a ship in water (if possible) to be done efficiently. http youtu.be H4ACKAUU3O0?t 3m51s I have started reading up on other information and looked at the other similar questions to mine 1) Water Ocean simulation and physics I have read this question fully, am looking at not using wind as said in this question but will use this as a reference when creating the final product. (I would like to add to the information from that question with the answers on this question.) 2) Resources of realistic water simulation? I have started going through the tutorials that the answer linked to and so far they seem good but do not look like they will answer my question. The water will have splashes in reaction to the objects in the water (particle effects I believe) and small waves will come off the objects in the water e.g. ripples. Also if you are a smart cookie that wants to be awesome you should include in your answer about putting a shader on the water. Also since the ships will be moving all at independent speeds and traveling through the sea, for efficiency I don't want to just make the water massive so is there a way to only render simulate the water within a certain radius from each of the ships? What I am looking for in an answer I would like to know the what tricks for making this type of simulation light weight can be used for these types of water simulations and specifically in unity. What limitations will I encounter when creating this and why they are limitations The basic work flow of creating something like this step by step. (e.g. step 1 to make the object that will be in the water) Are there any open source projects for these types of simulations? |

0 | The underlying mechanism in 'yield return www' of Unity3D Game Engine In the Unity3D game engine, a common code sequence for getting remote data is this WWW www new WWW("http remote.com data location with texture.png") yield return www What is the underlying mechanism here? I know we use the yield mechanism in order to allow the next frame to be processed, while the download is being completed. But what is going on under the hood when we do the yield return www ? What method is being called (if any, on the WWW class)? Is Unity using threads? Is the "upper" Unity layer getting hold of www instance and doing something? EDIT This question is specifically about Unity3D internals. I'm not interested in explanations of how yield statement works in C . Instead, I'm looking for an inside view of how Unity deals with these constructions, to allow, for example, to WWW to download a piece of data in a distributed manner across several frames. |
0 | How to build a game for linux in unity I made a game and uploaded it to a game site. I exported the build as windows mac OS and Linux.

0 | Occasional lag spikes in performance in heavily optimized game (profiler screenshots included) So I've been working on a mobile based platformer for a few years now. I've spent more than a year optimizing the game for mobile as much as I could. Almost every single one of my meshes are using Mobile Diffuse shader. When I test the performance of my game (on my phone) with the profiler, the frame rate stays at clean 60 fps for the most part. The CPU time fluctuates between 16 ms and 17 ms. The rendering statistics are also excellent, with draw calls fluctuating between 18 and 25, triangles fluctuating between 1.0k and 2.0k and vertices fluctuating between 2.0k and 3.1k. Below is a screenshot of the Rendering profiler when the game is running smoothly. I believe that for a mobile device, these should be very good numbers. However, every now and then, I see a spike in the profiler window (see below) According to the profiler, the spike is being caused by Render.OpaqueGeometry. Under normal scenarios (when the performance is smooth), Render.OpaqueGeometry takes between 1 ms and 2 ms of CPU time. However, as you can see in the screenshot above, Render.OpaqueGeometry is taking 5.36 ms of CPU time and the total CPU time has jumped to 24.16 ms. Based on my observations, this spike shows up once or twice per minute. Sometimes, several minutes go by without any spikes. And in very rare occasions, the spike can show up 3 times in a single minute (although I don't think that happened the last couple of times I tested it). So why do you guys think this is happening despite the game being heavily optimized? I read in a post in Unity Answers that Render.OpaqueGeometry spikes are frequent in all games and it's nothing to worry about. But do you think 2 spikes per minute is too frequent for a simple platformer? |

0 | Render texture seems to ignore camera background type I'm currently trying to pull a fog of war for an rts game, and planned it like this. (Unity 2020.2.7, URP 10.3.1) Use units field of view to generate a texture of what is seen (alpha 0). Create other render texture to generate fog (alpha gt 0 amp amp alpha lt 1) by not clearing camera buffer. Use the mask made between the two textures to cut the fog of war (alpha 1). Now i'm currently stuck at the 2nd step. Please check the image As you can see, the camera is doing what I want, but the render texture somehow clears the buffer, which just gives me the quot Use units field of view to generate a texture of what is seen (alpha 0). quot part again. This whole buffer thing has been hard to understand, i'm not sure if this implementation is right or not. I would be really thankful for any pointers given! D Cheers guys! |
0 | How can I get a Box Collider's "corners" (vertices) positions? I attached a Box Collider to a object, which has not the center as its pivot. Now I need the 8 corner points. Right now I can only get the points in a unrotated state.

0 | what is the math behind the parenting a transform in unity? in unity when you parent an object or transform with another object, all transform(position, rotation, scale) are calculated depending on that parent object. sometimes we need to know about the local data of that transform and sometimes we need to know that data based on the world axis. I need to know how that is implemented in math and vector functions. |
0 | Pushing Rigidbody forward doesn't go straight I have a object that pushing rigidbody forward when it's instantiated GameObject grenade Instantiate(projectilePrefab, shootPoint.position, shootPoint.rotation) grenade.GetComponent lt Rigidbody gt ().velocity transform.forward.normalized 50 It seems fine, but when I ran the game, projectile always not going straight and it's little bit moving left or right. So I thought that shoot point wasn't pointing the right direction or my crosshair didn't centered properly, but unfortunately there were nothing wrong with them.

And this is the error I get As you see the error, "cannot implicit convert type float to byte", the problem is caused by Time.deltaTime that returns a float value, and I need a byte due to Color32. Is there any way to turn Time.deltaTime to byte? Or should I use another type of color that use floating point numbers? I'm a beginner with Unity so I'm sorry if this has already been asked somewhere as I said, I can't find it on the Internet. |

0 | Picking up items and references Just a heads up, I'm sure there are much more efficient ways to do what I'm trying to do. I've even thought of some myself. However, at the moment, I'm mostly interested in getting this code to work. I think I understand exactly why it doesn't work, but I'm not sure how to fix it. Firstly, there is an ItemPickupTrigger script attached to the drop prefab. The purpose of this script is simply to modify a variable's truth value depending on whether or not the player is in range. This script must be attached to the drop prefab because it uses OnTriggerEnter OnTriggerExit. No problem here. Secondly, there is a pretty standard EnemyDrops script. public class EnemyDrops MonoBehaviour private EnemyHealth enemyHealth public GameObject dropPrefab private float randomNumber public bool objectDropped private bool numberGenerated public GameObject drop This is the correct offset for enemies' current y position of 1.083333 private Vector3 dropPositionOffset new Vector3(0f, 0.958333f, 0f) void Start() enemyHealth GetComponent lt EnemyHealth gt () void Update() if (enemyHealth.isDead amp amp !objectDropped amp amp !numberGenerated) randomNumber Random.value numberGenerated true if (randomNumber lt 1.0) DropObject() private void DropObject() objectDropped true drop GameObject.Instantiate(dropPrefab, transform.position dropPositionOffset, Quaternion.identity) It drops the object where the enemy has been killed. This script is attached to each enemy. As it's currently set up for testing purposes, an item will always drop. I'm sure there are better ways to do this, but it works, so no problem here. Finally, there is an ItemPickup script attached to an ItemController object which is otherwise pretty empty. I'm not even really sure why I decided to do it this way, I just thought that it might be better for things I wanted to do in the foreseeable future to not have this script attached to each enemy. Now get ready because the code below is problematic. public class ItemPickup MonoBehaviour private GameObject pickupWindow private bool windowOpen private GameObject drop private ItemPickupTrigger itemPickupTrigger void Start() pickupWindow GameObject.Find("Pickup Window") pickupWindow.SetActive(false) drop GameObject.Find("Drop") itemPickupTrigger drop.GetComponent lt ItemPickupTrigger gt () void Update() if (Input.GetKeyDown(KeyCode.R) amp amp itemPickupTrigger.playerInRange amp amp !windowOpen) pickupWindow.SetActive(true) windowOpen true else if (Input.GetKeyDown(KeyCode.R) amp amp windowOpen) pickupWindow.SetActive(false) windowOpen false For starters, it only works if there is a drop object already present when the script begins, but there shouldn't be a drop object then. Second, if I don't set the reference there, I'm not sure how to set itemPickupTrigger's reference, since I'm using it in update and need the reference set before then. Make a function called SetReferences() and call it early in Update()? Yeah, I'm pretty lost. Basically, I want to be able to open the "loot window" near any instantiated drop object in the game. Currently, that functionality only in a limited capacity (either only on a "preexisting" drop object in the scene or on one random instantiated drop object(?) depending on how I have been modifying the code). Help! |

0 | Unity Rigidbody gets pushed through collider by another rigidbody? I'm setting up the interior of a house in a 2D platformer. Inside the house is an NPC with a box collider and rigidbody attached, and the house is boxed in by four edge colliders. My character also has a collider and rigidbody. My NPC walks back and forth randomly, but when he pushes my character into the wall, the force of the push takes priority over the house's edge collider and my character gets pushed outside. Is there any way to give priority to the house's collider somehow, without removing the NPC's rigidbody? |

0 | Rope 2D Hinge disconnection I have a game that needs to use a rope like mechanic should do two things. Restrict Player's Movement within the length of the rope. In other words, some kind of rubber band that brings the player back to the rope imitating real world. Rope sections should not go beyond their hinge limits I'm using the Rigidbody2D.velocity to move the player, the hinges do not stop the player from moving beyond the rope's limits. Thus, causing this visually breaking of the joints. This is more visible when we flip the player's scale x to 1 since we're moving the player to the left. This also causes the rope segments to spasm or rotate at absurd speeds. The break force is set to Infinity. I tried looking online for a solution but I'm not entirely sure what joint to use. These are my hinge settings Questions How do I fix the rope segments to not have these gaps? How do I safely flip the player without causing problems in the rope? |

0 | Disable system sounds in Unity? I've got an editor script in Unity 5 that uses the cursor position in the scene view to change objects in the scene when you press the space key. This all works perfectly, except that Unity thinks that space isn't a valid key to press, so it makes the system "boop" sound to let you know that it's invalid or that nothing happened. So, focus is on scene view, I press space, my script triggers, and the mac system "boop" sound activates. It spams the sound if you hold it down. Is there a way to Disable the system boops in Unity or Add space to registered hotkeys stop unity from triggering the system sound for a specific key (just to be clear, the script works, I'm just wondering about disabling the sound) |
