Question: Hello Open Assistant, I need your help to create a animation matching blueprint in unreal engine 5. Please provide me with all the steps and also I would like a graphic representation of the nodes and how are interconnected. Thanks in Advance

Answer: I can provide you with a step-by-step guide on creating an animation matching blueprint in Unreal Engine 5. You can follow these steps and create the blueprint in the editor.

Step 1: Create Animation Assets
Before creating the animation matching blueprint, you need to have the required animation assets, such as a skeletal mesh and animation sequences for different character movements (idle, walk, run, etc.).

Step 2: Create an Animation Blueprint

1. In Unreal Engine 5, go to the "Content Browser."
1. Right-click, select "Animation," and then "Animation Blueprint."
1. Choose the appropriate Skeleton for your character and click "OK."
1. Name the Animation Blueprint, e.g., "CharacterAnimationBP."

Step 3: Edit the Animation Blueprint

1. Double-click on the "CharacterAnimationBP" to open the Animation Blueprint Editor.
1. In the "AnimGraph" section, you will create the logic for blending animations.

Step 4: Add a State Machine

1. Right-click in the AnimGraph, and add a "New State Machine."
1. Name it, e.g., "Locomotion."

Step 5: Create States and Transitions

1. Double-click the "Locomotion" state machine to edit it.
1. Add three states: "Idle," "Walk," and "Run." You can do this by right-clicking in the graph and selecting "Add State," then naming them accordingly.
1. Connect the entry node to "Idle."
1. Create transitions between all the states. Click and drag from one state to another to create a transition.

Step 6: Configure State Animations

1. Double-click on each state (Idle, Walk, and Run) and select the appropriate animation sequence for each.

Step 7: Create a Speed Variable

1. Go to the "My Blueprint" tab and create a new float variable named "Speed."
1. Compile the blueprint to save the variable.

Step 8: Calculate Speed

1. Go to the "Event Graph" tab.
1. From the "Event Blueprint Update Animation" node, pull a wire and search for "Try Get Pawn Owner" and add it.
1. Pull a wire from the "Return Value" of the "Try Get Pawn Owner" node and search for "Get Velocity" and add it.
1. Pull a wire from the "Return Value" of the "Get Velocity" node and search for "Vector Length" and add it.
1. Pull a wire from the "Return Value" of the "Vector Length" node and connect it to the "Set Speed" node's input pin.

Step 9: Configure Transition Rules

1. Go back to the "Locomotion" state machine.
1. Double-click on the transitions between the states to edit their rules.
1. For the transition from "Idle" to "Walk," add a condition: "Speed > 0."
1. For the transition from "Walk" to "Idle," add a condition: "Speed <= 0."
1. For the transition from "Walk" to "Run," add a condition: "Speed > 150" (or your desired threshold).
1. For the transition from "Run" to "Walk," add a condition: "Speed <= 150" (or your desired threshold).

Step 10: Test the Blueprint

1. Assign the "CharacterAnimationBP" to your character's Skeletal Mesh in the character blueprint.
1. Run the game and check if the character transitions smoothly between idle, walk, and run animations based on its speed.

You can customize the transitions and blend times according to your needs. You can also add more complex logic and additional states if required. The above steps provide a basic setup for animation matching using a blueprint in Unreal Engine 5. Once you're familiar with the process, you can experiment with more advanced features such as blend spaces, layered blend per bone, or custom animation nodes to further refine and enhance your character's animations.

Remember that the node setup might vary slightly based on your specific requirements, animation sequences, and character movement setup. By following this guide and making adjustments as needed, you should be able to create an animation matching blueprint in Unreal Engine 5 for a character with smooth transitions between different movement states.
