0 | What size should I scale my sprites to before importing them to Unity? I'm developing a game with an 8bit look. I want to target iOS and Android devices. The real resolution for my backgrounds is 108 x 192. Should I should put them in that same resolution and scale them in Unity using FilterMode or s there a way to make the camera use nearest neighbor? Or should I resize all my sprites before importing to something bigger? And if so to what size? 1920 x 1080? |
0 | Unet, client is unable to control spawned units I am trying to create a simple table top game with Unet. Right now I am just trying to get simple spawn mechanics working. The issue I am having is that the host computer can spawn and control objects correctly. The object gets instantiated, it gets added as a child to the armylist gameObject correctly. The client is able to see the object move around. Etc. Everything is working correctly it appears from the host side. The client however, can only instantiate a game object then they lose all reference to it. Also when it gets instantiated it does not become a child of the correct object, it is just its own object in the scene without a parent. The host computer can see the object be spawned. I am not sure what I am doing wrong, I have tried reading the documentation but to no avail. Any help would be greatly appreciated. public class PlayerManager NetworkBehaviour SerializeField GameObject tank SerializeField Camera PlayerCamera SerializeField GameObject ArmyList new GameObject 50 private Vector3 placePos GameObject currentUnit void Start () void Update () if (Input.GetKeyDown (KeyCode.A)) Cmd place initial units () Rpc PlaceUnit () Command void Cmd place initial units() currentUnit Instantiate(tank, placePos, Quaternion.identity) as GameObject currentUnit.transform.parent transform.GetChild(0) ArmyList 0 transform.GetChild (0).GetChild (0).gameObject NetworkServer.SpawnWithClientAuthority (currentUnit, connectionToClient) void Rpc PlaceUnit() if (ArmyList 0 ! null) RaycastHit hit if (Physics.Raycast (PlayerCamera.ScreenPointToRay (Input.mousePosition), out hit)) if (ArmyList 0 .tag "ground") placePos new Vector3 (hit.point.x, 1f, hit.point.z) else placePos new Vector3 (hit.point.x, 1.2f, hit.point.z) ArmyList 0 .transform.position placePos |
0 | Move camera around player while facing player My player has the following hierarchy Hero (GameObject) Model (child of "Hero", centered at 0 0 0) Camera (child of "Hero") The camera should be allowed to change its position around the Model in a circle ("rotate around the center") rotate so that it always faces the Model move up and down move nearer and further from to the Model I know how to do that using Quaternions, but as I'm doing this in a coroutine and using Lerp, I found myself in situations where the camera would get right through the model as this was the shortest path between the destination and the target vector. I would now like to use pure angles (Sin and Cos), preferrably without LookAt. Can somebody share how I would position and rotate the camera according to the angle, perhaps even taking a camera height variable into account as the camera should also be able to move up and down, still facing the player? That would be the bomb! |
0 | Accessing RigidBody2d from OnTriggerEnter2D(Collider) I have the following script on my water object which, when the Players ship triggers it, the ships gravity is inverted to give the sense of buoyancy. I have added a 'print' statement to prove that the collision is working and that the Name condition check works, which it does. However it throws an error when trying to access the plays ship Rigidbody2D property to then access the GravityScale with the message There is no 'Rigidbody2D' attached to the "Player" game object, but a script is trying to access it. You probably need to add a Rigidbody2D to the game object "Player"... void OnTriggerEnter2D(Collider2D coll) if (coll.gameObject.name "Player") print("Player Hit Water") Rigidbody2D tmp coll.gameObject.GetComponent lt Rigidbody2D gt () tmp.gravityScale 1 Update It turns out this code is fine it was the structure of my gameobjects that was the problem as the Rigidbody2D was in the child object, not the parent. See comments below for details. |
0 | Handling an item database with procedurally generated items? Let's say you have an item database which has every item in your game. This works fine for regular items like a Health Potion, a normal Iron Sword etc, because these items have ItemID's so we can get an exact copy of this item. But what if we have an Iron Sword with an enchantment ' 5 Fire Damage'? (or whatever) If you were to save that item to a player's inventory, exit the game and load the game, the item will load as a regular Iron Sword, because it still has that ID. Specifically, how would you save that item to a file? I'm using Unity, so to save the Player's inventory, I use PlayerPrefs.SetInt("Inventory " i, inventory i .ItemId ) Would you create a custom item ID for every item with enchantments or is there a better way around this? |
0 | Unity and Apple TV Remote control sensitivity I'm developing a game for Apple TV and I'm responding to the swipe gesture using if (Input.GetKeyUp(KeyCode.Joystick1Button4)) DoSomething() But the problem is that this is too sensitive, and triggers when the player didn't intentionally swipe. Is there any way to set the sensitivity? |
0 | How to create button prompts for interactable objects in Unity? I have a class of objects tagged as interactables that my player can interact with when within range. When my player is near them, I want to display a button prompt at the bottom of the screen, along with a description of the type of interaction possible (for example, "inspect", "use", etc.). I want to account for the possibility that the player might be within range of two or more of them at once, and thus allow him to toggle through them, displaying their button prompts in turn. If my player interacts with something which generates a text box or other modal, I want the button prompt to disappear, but to return when the text box or modal is closed. Any advice on how to go about achieving this? I've done it in the past in different engines, but I have always been unhappy with how convoluted my method was. I'd like to hear how others might tackle this. Given how common this kind of thing is in games, I'm surprised I haven't found a good tutorial on it yet. You can be as general or as specific as you'd like in your answer. |

0 | How to solve problem with Terrain Flashing and then disappears when flying away? I am making flight simulator( my first Unity project) , the biggest challenge so far is terrain, so whenever I fly away from it (not that far) the terrain starts flashing and disappears which is just green mountains, so when i come back to it, i have no idea where its position is, but it suddenly appears (again flashing) when I am close , the terrain size is normal but it's on top of a huge other terrain (about 100,000 100,000 which is the max),I tried changing pixel error and base map distance, no change, I looked at big terrain solutions online, but non of them really helped me, Any advice? Thanks |
0 | Colliding wiith a smooth line of blocks I'm having a strange problem. I'm creating a 2D platformer, and creating the gameplay map by reading a csv file and placing prefabs of the appropriate type on map. One part of the map is a simple straight line of blocks. I can move across them no problem except that there's this particular area where I simply can't move over it. (In the image the blue tiles are the ones I'm colliding with. I added that to help debug it). The block itself is not higher than any other blocks in the rest of the line, comes from the same prefab et cetera. If I remove "Fixed Angle" from the player character block, when passing from this block it'll start to rotate wildly instead suggesting that it's colliding with some sort of edge. Here's the code I'm using to generate the blocks for (int x 0 x lt tiles.GetLength(0) x ) for (int y 0 y lt tiles.GetLength(1) y ) var tile tiles x, y if (tile.HasValue) switch (tile.Value) case TileType.MAIN CHARACTER Instantiate(mainCharacter, new Vector3(x TILE SIZE, y TILE SIZE), Quaternion.identity) break case TileType.NORMAL Instantiate(maintile, new Vector3(x TILE SIZE, y TILE SIZE), Quaternion.identity) break default throw new NotImplementedException("No code for tile value " tile.ToString()) So, what am I doing wrong exactly? Is there a way to tell Unity to ignore these 'tiny' collisions? EDIT 1 If it makes any difference, I'm using BoxColliders2D around each block |
0 | Unity Easier way to resize group of buttons to the same size I have a canvas with buttons, with a script attached to each button. This script creates an array for buttons and resizes every button to the same size as the longest one in that array (the button with the longest line of text in it).

0 | Optimal solution to render sprites with transparent edges in Unity Since I'm currently developing a 2D game for mobiles, overdraw and drawcall count is my first priority in the design of the application I've thought initially to split each sprite in two parts one where each pixel is fully opaque (to render with cutout shaders in front to back order) and the other part with semi transparent edges (which will be ordered back to front) Since I need to support ES2.0 devices, I can't use texture arrays and I need to fit as many sprites as possible in a single 2048x2048 texture atlas to reduce drawcalls and ensure mobile compatibility, but as you can see from this picture Splitting sprites in opaque and non opaque parts will certainly double the space occupied in the atlas, thus decreasing by half the potential amount of consecutive sprites I can draw in a single drawcall This way, I'm paying drawcalls to reduce overdraw. By rendering the entire sprite with transparent shaders I'd pay overdraw to reduce drawcalls. Am I missing something? Is there a better approach? |
0 | Most efficient way to achieve the following 2D heat wave background effect?

0 | Changing Pixels Per Unit First off, excuse my ignorance. I am just getting started in game dev. and ran into a little issue. So I had these weird rippling lines going across my screen, and saw in a couple forums that this means I don't have what is called a quot pixel perfect quot game. To fix this, I am supposed to change the pixels per unit of each sprite down to 1. Currently I had it on 32 because that is my sprite size and I am a complete noob. Now, I change it down to one but it completely destroyed my game. Everything that is generated on my map grid is sucked into the center in this giant orb of sprites (I procedurally generate my map off a grid of 1 0s). I am guessing there is just a setting or some such thing that I am missing. Any ideas? Also would be happy with an alternative to remove the rippling lines. |
0 | Need some advice on how to decide where to implement my enemy behaviours I'm in the middle of writing a platformer game in Unity using C . I have my character, if he presses the kick button his state switches to kicking. During this "kicking" state the character doesn't actually do anything, he only publicly exposes the kicking information such as kickForce etc. The enemies however have a check in their update functions for the players isKicking value, if he is and the enemy lies within the range for being kicked by the player then the enemy has forces applied to itself and such. All this works fine but I've been thinking about future implementation of different enemy types, if I want to implement other types of enemies that do not behave the same this same script will not work. To me this is inintutive, part of me thinks that the kicking behavior should be in the player class, he should retrieve all enemies within the area of kicking and run them through some sort of KickObject method. However this is my very issue, I am unsure of what the cleanest and most straightforward (and easily extendable) way of doing this is. I have this problem in general when it comes to implementing the structure of the game, i don't know the best answer and I feel that often when I am planning things they get much more complicated than I had originally planned for down the line and the structure i had in place starts to fall apart. Any advice on this matter would be greatly appreciated. TL DR For kicking enemies, should the behaviour be applied by the player or is the method of every enemy having its own "be kicked" code the better way to do this. General game development code structure questions. |
0 | Unity 3D C Shifting beetween worlds? Let's say I want to replicate Planeshifting from Legacy of Kain Soul Reaver in Unity. There are 2 realms Spectral realm and Material realm. The Spectral realm is based on the Material realm, only has the geometry distorted and certain objects fade out become non interactive. In Soul Reaver, it is used as means to go to areas where you normally wouldn't be able to in Material (distorting geometry), to use other powers (such as going through grates). My question is Is it even possible at all to implement this in Unity 3D? (I would need the Scene(level) or the objects to have 2 states somehow that I could switch beetween distort to real time.) |

0 | Using Quaternions What can I do with them? (without the maths) I am a Game Developer and did not study Mathematics. So I only want to use Quaternions as a tool. And to be able to work with 3D rotation, it's necessary to use Quaternions (Or Matrixes, but let's stay at Quaternions here in this Question). I think it's important for many developers to use them. That's why I want to share my knowledge and hopefully fill the holes I have. Now.... So as far as I understood A Quaternion can describe 2 things The current orientation of a 3d Object. The rotation transformation a Object could do. (rotationChange) You can do with a Quaternion Multiplications Quaternion endOrientation Quaternion rotationChange Quaternion currentOrientation So for example My 3D Object is turned 90 to left and my rotation I multiply is a rotation 180 to right, in the end my 3D Object 90 is turned to right. Quaternion rotationChange Quaternion endRotation Quaternion.Inverse(startRotation) With this you get a rotationChange, which can be applied to another Orientation. Vector3 endPostion Quaternion rotationChange Vector3 currentPosition So for example My 3D Object is on Position (0,0,0) and my rotation I multiply is a rotation 180 to right, my endposition is something like (0, 50,0) . Inside that Quaternion there is a Axis and a rotation around that axis. You turn your point around that axis Y Degrees. Vector3 rotatedOffsetVector Quaternion rotationChange Vector3 currentOffsetVector For example My start direction is showing UP (0,1,0), and my rotation I multiply is a rotation 180 to right, my end direction is showing down. (0, 1,0) Blending (Lerp and Slerp) Quaternion currentOrientation Quaternion.Slerp(startOrientation, endOrientation , interpolator) if the interpolator is 1 currentOrientation endOrientation if the interpolator is 0 currentOrientation startOrientation Slerp interpolates more precise, Lerp interpolates more performant. My Question(s) Is everything I explained until now correct? Is that "all" you can do with Quaternions? (obv. not) What else can you do with them? What are the Dot product and the Cross product between 2 Quaternions good for? Edit Updated Question with some answers |
0 | UI Dropdown Is it possible to have a custom value type instead of an index? I'm using the UI Dropdown component which lets you set the text of an option (OptionData) only. The value of an option is the index position in the options list, so there is no way to set this. My problem is that I have a dictionary lt string, tile gt that I use to populate the dropdown options, but I would like the value of the option to be the id of the tile class, not the index position. Edit I know I can access elements from the list by using the value (index). list dropdown.value .id But I wanted to see about extending the dropdown with this small change, as I have some other changes I would like to make, but wanted to start with something simple first just to get an idea of what is possile. I do not want someone to post a full code solution. Am mostly after some pointers. Looking at the dropdown class, I don't see how I can extend it to modify some things (value in this case), it looks like I would have to implement by own version? Some code will make this a little clearer I think All tiles into list. List lt Tile gt list new List lt Tile gt (mydictionary.Values) Sort all tiles based on the tile name. list.Sort((x,y) gt x.name.CompareTo(y.name)) Current way to add list to dropdown. for(int i 0 i lt list.Count i ) dropdown.options.Add(new Dropdown.OptionData() text list i .name Tile name (string). ) ) What I want to do. for(int i 0 i lt list.Count i ) dropdown.options.Add(new Dropdown.OptionData() text list i .name, Tile name (string). value list i .id Unqiue tile id (string). ) ) Getting changed value dropdown.onValueChanged.AddListener(delegate Debug.Log(dropdown.value) Instead of the index selected, I want the tile id ) Or if the value is needed internally for some reason, then maybe an extra property that can be set and retrieved. for(int i 0 i lt list.Count i ) dropdown.options.Add(new Dropdown.OptionData() text list i .name, Tile name (string). tile id list i .id Unqiue tile id (string). ) ) dropdown.onValueChanged.AddListener(delegate Debug.Log(dropdown.tile id) ) I took a look at the DropDown class to see if I could extend it and add the "tile id" option in, but I got completely lost on what to do, as I am still quite new to C . https bitbucket.org Unity Technologies ui src a3f89d5f7d145e4b6fa11cf9f2de768fea2c500f UnityEngine.UI UI Core Dropdown.cs https docs.unity3d.com ScriptReference UI.Dropdown.html |

So I'm trying to decide what server software I want to build it for. I'm looking at RakNet, and it's appealing because it's available two ways independently and as part of the networking solution of Unity3D.

0 | Agent trying to reach same position as other agents, instead start spinning in place I create units in my game and have a rally point where they should walk to when created, like Age of Empires. My problem is that since they compete for this position after a while, sometimes they end up doing this https gfycat.com decentquestionableandeancondor https gfycat.com densehonoredgalapagosalbatross As you can see one of the guys cant reach the rally point, so he starts rotating. I realize this has to do with stopping distance, but no matter how high I set the stopping distance this eventually becomes a problem when there are many enough units.

0 | I have a game based on combining 2 ingredients to create a product. What is the best way to code this? (Unity) So to go a bit more in depth, in my game, you can combine a variety of ingredients to make a product. For example, you could combine water and dirt to make mud. What I am currently doing to achieve this is by listing each combination possibility that a particular ingredient has. The one thing i managed to do to make it a little more efficient is that I managed to remove duplicates (So for example, if i have coded ingredientA IngredientB Cheese, there isn't another entry for IngredientB Ingredient A Cheese). The problem I have with my method is that it is very annoying adding new ingredients. If i do so, I have to go back to every previous ingredient i have coded, and add it's interaction with the ingredient(s) i want to add. The amount of ingredients I have means this is becoming increasingly time consuming. Is there a better way to do this? This is a Unity game, coded in C . Let me know if you need any further info. |
0 | How best to structure manage hundreds of 'in game' characters I've been making a simple RTS game, which contains hundreds of characters like Crusader Kings 2, in Unity. For storing them the easiest option would be to use scriptable objects, but that isn't a good solution as you cannot create new ones at runtime. So I created a C class called "Character" which contains all data. Everything is working fine, but as the game simulates it constantly creates new characters and kill some characters (as in game events happen). As the game continuously simulates it creates 1000s of characters. I added a simple check to make sure a character is "Alive" while processing its function. So it helps performance, but I can't remove "Character" if he she is dead, because I need his her information while creating the family tree. Is a list is the best way to save data for my game? Or it will give problems once there are 10000s of a character created? One possible solution is to make another list once the list reaches a certain amount and move all dead characters in them. |

0 | Fastest way to assign sprites to components in Unity I'm using a sprite atlas and Unity's built in sprite editor to tease out the individual images. Specifically, I have a single texture containing lots and lots of icons for armor, and I am assigning those to a Sprite field of a Component. However, the process of manually assigning sprites to the component via drag and drop is tedious. Is there a faster way to do this? Perhaps a way I can bulk assign sprites to a component? Update This is the code of the final solution. In short, the easiest thing to do is to put the texture atlas in the Resources folder and then programmatically access the sprites by name. private void MergeTextureAtlas(string atlasName, Dictionary lt ItemSubType, List lt Sprite gt gt spriteLookup) Sprite atlasSprites Resources.LoadAll lt Sprite gt (atlasName) Assert.IsNotNull(atlasSprites, atlasName) Assert.IsTrue(atlasSprites.Length gt 0, atlasName) int spritesLoaded 0 foreach (ItemSubType itemSubType in Enum.GetValues(typeof(ItemSubType))) string subTypeFriendlyName ItemSubTypeHelper.GetSubTypeName(itemSubType) foreach (Sprite atlasSprite in atlasSprites) if (atlasSprite.name.Contains(subTypeFriendlyName)) if (!spriteLookup.ContainsKey(itemSubType)) spriteLookup.Add(itemSubType, new List lt Sprite gt ()) spriteLookup itemSubType .Add(atlasSprite) spritesLoaded if (spritesLoaded 0) Debug.LogWarning(String.Format( "Found 0 new sprites in texture atlas ' 0 '.", atlasName)) |

0 | How to implement GIF insertion in Unity? "XYZ App doesn't support image insertion here" I'm making an Android App with Unity, which has a chat service in it. And I would like to handle sending images or GIFs via Gboard. Currently when the user selects a TextField, his keyboard comes up, which is let's say GBoard. And now when I click on a GIF or a Sticker, it says XYZ App doesn't support image insertion here So how could I implement it? Or more precisely, how can I define what method will be be called in my application when the user tries to send a GIF? Because my first thought to implement it, is like it's done in all other apps every GIF would be in a separate message, and when the user clicks on a GIF it instantly sends a special GIF message, which will be rendered for example as an animated texture. But how could I subscribe to this event in the first place? Thanks in advance! |

0 | How to make a road terrain for unity game? im making a FP game in low poly style. I want to make some terrains for my game, with roads, trees, rocks, buildings and e.t.c. Unity terrains are not as good as i thought. They allow a good tool for placing multiple objects (like tree to sprite tools, trees mesh copy for perfomance), but the terrain building tool itself is very poor, so i cant use 3d terrain, because there will be no great tools for placing surroundings. So my plan is make low poly mountains, trees, rocks in Blender, then make a simple terrain with hills in unity and just place my surrounding objects on it. I have some troubles, for example roads. I have a road elements, and by connecting amp banding them i can get a really nice road. But how can i make a road on Unity's terrain? For example it could be useful to export unity terrain as a 3d mesh to Blender, then make my roadways and export them in Unity. |

0 | UV Tiling Offset input values from World Position incorrect behavior? I'm using ShaderGraph in 2020.1.0f1. I have some shader experience, but it's all been handwriting shaders. I have experience with node based things of this nature by way of Substance Designer. I'm working on a shader that should allow for seamless visibility between quads by changing the UV offset of a noise pattern based on the world position of the quad. That said, I'm running into two things. This short (0 05) video shows how I'm expecting this to work as the X Y values of the UV Offset are changed, the continuous flow of the noise is smooth. https youtu.be YAd9BtAWVRM So, I add a position node and a split node, feed the world position into the split, and feed R G from the split to X Y of the Vector2 node. That does two things it makes the preview boxes 3D (becomes a sphere instead of a quad), and quot expands quot the apparent tiling I'm guessing this is because the value from the split is a Vector1 rather than a float, though it seems odd that there's no implicit conversion, or that Vector1 values applied to UV Offset would change the actual appearance. So, is this due to it being a Vector1 rather than a float? If so, is there a node that can convert from Vector1 to float? Am I going about this the wrong way entirely? |

0 | unity apply item animation to character I'm trying to change the attack animation of my player in relation to the attack animation for the item he has in his hand. For example, the default attack animation of my player is puching and once he picked up a sword I want his attack animation to be sword attack, for a hammer a hammer attack, etc .. I searched a lot on the internet but didn't find much, I saw a few post talking about AnimatorOverrideController but I'm not sure if it's what I need because it overrides every animation clip of the AnimatorController. In my case I just want to change the attack Animation Clip. So if you cloud give me some tips about the right way to do it, I would really appreciate because I'm a bit confused. Thanks Edit BTW, I'm in Unity 3d |

0 | How to access "move" values from move node in Rain behavior tree? I have a blend tree for the NPC that takes an "input magnitude" value 0 to 1.0 for how fast the character should move...and an "angular input" float negative pi to positive pi for how fast the character should turn. How do I get the rain behavior tree to update these values correctly in the behavior tree "set parameter" leaves? I see that I can set the parameter with some kind of variable name, but I don't see where I can specify that variable with a script...and I don't see how I can access the "move" instructions given from the move node on the behavior tree, and use them to set the variables either. How would I accomplish this steering with Rain? |
0 | Determining whether a large building should be split into multiple scenes This is about designing a first person retro game in Unity3d. In this game the player would walk around inside a large maze like building that has corridors on 10 15 different floors. Each floor has a corridor that is set up as a square that surrounds all other corridors (which are set more or less randomly, like a maze) on that particular floor. The length of each side of this surrounding corridor is about 100 steps. So, considering that this building would have about 10 15 floors constructed like this, the question I wanted to ask is whether it can be included as a single scene? Or does the answer to this depend also on other factors such as the type of game assets and target devices? |

0 | When an animation involves movement, where is the movement better to implement? For context, I am using Blender and Unity. Regarding the question, as an example, in some games, when you get hit, your character tucks a bit and gets knocked back a few distance. The tucking animation I want to implement in Blender but how about the knockback distance? Do you move your model in Blender (tuck and knockback), or do you do the tuck animation only (tuck in place) and then handle the knockback in Unity (basically triggering the tuck animation and then moving the model backwards a bit). My question basically is, what's commonly done and if there's any specific reason, why? |
0 | Instantiate and launch prefab that's overlapping player? I m very new to Unity and C . I m trying to create my first game and I have now invested about 15 hours trying to find solutions to this issue...I m stumped! My player sprite (blue square) needs to launch a prefab sprite (red circle) of similar size appearing to originate from itself. Here is a GIF of what I have so far...I don t want the blue cube to collide and go flying. After clicking and dragging on Player (drag to aim) via OnMouseDrag to set the target vector, I m trying to Instantiate a prefab sprite (Dynamic RigidBody2D, CircleCollider2D) using the Player sprite s position (a Dynamic RigidBody2D, BoxCollider2D) and have it APPEAR to be originating from inside the Player object. Launch is triggered via function called in OnMouseUp. Both objects should immediately come under control of Physics to collide with the environment which will include other moving RigidBody2D objects later. Targeting should allow 360 degrees to include straight into an obstacle allowing rebound effect. Here is some excerpts of my code using System.Collections using UnityEngine public class Teleportation Grenade MonoBehaviour This script is attached to Player and requires projectile prefab. tested with thrust set between 100 and 200. public float thrust public Transform prefab public LineRenderer playerShotLine private Vector2 playerToMouse private Vector2 targetVector ... void OnMouseDrag() Vector3 mouseWorldPoint Camera.main.ScreenToWorldPoint (Input.mousePosition) Vector2 playerToMouse mouseWorldPoint transform.position mouseWorldPoint.z 0f playerShotLine.SetPosition (0, transform.position) playerShotLine.SetPosition (1, mouseWorldPoint) playerShotLine.sortingOrder 3 opposite direction of line renderer targetVector playerToMouse void OnMouseUp() SpawnPrefab () void SpawnPrefab() Instantiate(prefab, new Vector3(transform.position.x, transform.position.y, 0), Quaternion.identity) prefab.GetComponent lt Rigidbody2D gt ().AddForce (targetVector thrust, ForceMode2D.Impulse) This is only one of many, many iterations. It's the gist of it though. I appreciate any insight from the community. |

0 | My object just automatically "launch" or do stuff without me clicking on my mouse when it respawn? I've already set the ball (my object) initially at the start where I have to click for the ball to launch from the paddle (it's a ping pong game). private void LockBallToPaddle() Vector2 paddlePos new Vector2(Paddle.transform.position.x, Paddle.transform.position.y) transform.position paddlePos paddleToBall For the ball to stick to the paddle Launch the Ball private void LaunchBall() if (Input.GetMouseButtonDown(0)) hasStarted true rbBall.velocity new Vector2(Random.Range( 2f, 2f),speedVelocity) Both of which I put under Update() private void LaunchBall() if (Input.GetMouseButtonDown(0)) hasStarted true rbBall.velocity new Vector2(Random.Range( 2f, 2f),speedVelocity) Now the problem is when my ball hits a certain collider, I want it to respawn the position back to the paddle. So instead of Destroy the game object, I just copy and paste those same methods under collision if (collision.gameObject.tag quot bottom quot ) LockBallToPaddle() LaunchBalls() But now it just launches straight away from the paddle when hit the collision without me clicking anything like what quot Launchballs() quot intended to. What should I do? |
0 | How can I cast light onto a sprite in 3D environment? I'm making a 2.5D game, where 2D sprites are in a 3D environment. I'm using URP and I have a problem with lighting the sprites. The sprites are lighting up from behind, and not front. I tried with directional, spot and point lights but the result is the same no matter what official shader I use they only light up when they receive light from behind. Front light has no effect whatsoever on the sprites. I spent the entire day looking for a solution but I've got almost nothing. Only solution I saw someone else mention is making the game object with the quot sprite renderer quot on, a child of another gameobject and rotate it 180 degrees on Y. But that is not an option for me cause I'm using custom scripts to rotate that game object already. So can there be a custom shader? Can one be created using shadergraph maybe? I know some others have faced the same problem but did anyone really solve it? Thanks. |
0 | Unity Android game all squashed in center of screen (portrait layout), help I'm developing a demo for Android game in Unity with portrait layout.

0 | Using shared memory instead of marshalling for C native plugins in Unity? So I'm a C developer who has been playing with C for a week or two in order to get acquainted with Unity, and I'm curious about the marshalling process used to transfer data for use in C native plugins. From what I can tell, the general consensus is that while using effective C plugins can be a performance increase for computation heavy tasks, the marshalling process of transferring data can be significantly slower than the potential gains provided by the C flexibility. I'm familiar with how shared memory works in C and it appears C has the functionality required to use the buffers as well. From what I understand, the process of marshalling is slow due to copying, creating buffers and transferring chunks from one memory segment into another. Even though there's the problem of cache coherency when operating in shared memory, it may be less than the cost incurred by marshalling. I'm sure I'll have to do some experimenting. Does anyone have thoughts or experience with using shared memory or marshalling in Unity who could weigh in on the question? |
0 | Switching from software Engineer to Game developer I don't know if this is the right place to ask this. I've been working as a software engineer for 3.5 years so far, mostly web apps, mobile apps, web pages in banking systems, educational, etc but I always wanted to work as a game developer. Currently I have a university degree in CS, and I'm attending a masters degree in Apps design. I've very little experience in game dev (only for hobby), some space shooters and some steps in unity, also I took some courses of blender, and did some simple sprites (those 8 bit characters but animate them is a big problem for me atm.) but I've never gone too far. I know I cannot focus on all aspects of game development, because it is a huge world integrated with different disciplines, but I need to make a portfolio with some of my games at least. (I only have partial prototypes, some of them work, some don't...) I need some advise of people who are in the game business. Which platform framework do you recommend for me ? I already know a bit of Unity and I feel pretty comfortable with it. I can get some assets to work with (models audio, etc), there are some free material in the store, and I have budget to spend on that too if necessary. How do game companies hire people? What am I suppose to aim for a job? I mean this is a world full of disciplines and I need to focus in something particular I guess, I'm a senior frontend developer too, so I guess I should focus on coding. I think portfolio is the best way of showing your work. Any suggestions are welcome! thanks! |
0 | How to make a 'Picture book Cutscene' in Unity 2D with simple 2D images? I'm trying to implement a simple cutscene system in my Unity game, preferably one that allows cutscenes to play at the start and end of each of the levels. What I was imagining was pretty similar to A Hat in Time's 'storybooks' from it's time rifts, but full screen and advanced with a single key. The images are simple and comic like, and I was wondering how to implement such a feature since it feels like it's a bit different to Unity's pre existing Timeline system, as there isn't many moving parts. How do I go about approaching this problem? At least, I don't know how to get the project to a state where a person can press a key to turn to the next page (whether or not there's a visual transition to the next is optional) and once it's done, to start the actual level scene. Do I still use the Timeline for this? I know I could potentially use an empty game management prefab in order to set up when to play the cutscenes, however. |
0 | How should I store trading cards? I'm working on a Magic esque TCG in Unity. Currently, the cards themselves are all prefabs I have a Satyr Archer prefab, a Candle Wisp prefab, etc. This works fine for now, since I only have a few cards, but by the time I get to several hundred, I feel that this may become unwieldy. Are prefabs a good way to store a large list of cards? Should I be making those prefabs using an XML document and a script? |

0 | How to figure out what's moving my GameObject? I have a GameObject as part of a complex scene with a handful of interconnected parts, that's moving when it shouldn't be. I've tried running under the debugger and setting breakpoints on all of the script points that are supposed to move its Transform, and ensured that none of them are firing. There seems to be some "spooky action at a distance" going on, some rogue script doing something I don't want it to be doing, but I can't for the life of me figure out where it is. What I'd really like is some way to set a "breakpoint" on the object's Transform that will break me into the debugger when it gets moved by any script, but that doesn't appear to be supported. Is there any way to figure out exactly what it is that's moving my object around when it shouldn't be? (And before anyone says "trial and error, disable components and see when it stops moving," I already know exactly which component to disable to make it stop moving. Unfortunately, that isn't helping track down the problem because the movement isn't coming directly from that component's MonoBehaviour script.) |
0 | Reading data from files in Unity on Android I have successfully read in and written level data using .dat files on unity PC builds, but compiling for android stops me from being able to read in information from the resources folder. I was under the impression that when it's compiled the resources folder was still accessible? I could create a .dat file in the persistent data path but that means hard coding the information only to serialize it, rather than the data originating from the .dat file itself. How can I include this data within the apk without hard coding it? Here is my code, working on PC Stream file File.Open("Assets Resources levelData.dat", FileMode.Open) levelData (LevelDataFile)bf.Deserialize(file) file.Close() Edit for context, the level data is very simple as this is just a puzzle game, and each level will just have a few starting positions and obstacles etc, and there will be 100 levels, hence I'm not doing a scene per level. |
