Define action maps and actions
Configure bindings and interactions
Set up action types (value, button, passthrough)

Device Support

Implement scheme switching
Support local multiplayer
Configure device requirements

Runtime Handling

Generate C# input classes
Handle input events
Implement rebinding UI
Manage device changes

Prerequisites

Unity 2021.3+
Input System package installed

Usage Patterns

Input Actions Asset

// Generated PlayerInput class usage
public class PlayerController : MonoBehaviour
{
    private PlayerInputActions inputActions;

    void Awake()
    {
        inputActions = new PlayerInputActions();
    }

    void OnEnable()
    {
        inputActions.Gameplay.Enable();
        inputActions.Gameplay.Jump.performed += OnJump;
        inputActions.Gameplay.Move.performed += OnMove;
    }

    void OnDisable()
    {
        inputActions.Gameplay.Disable();
    }

    void OnJump(InputAction.CallbackContext ctx)
    {
        // Handle jump
    }

    void OnMove(InputAction.CallbackContext ctx)
    {
        Vector2 movement = ctx.ReadValue<Vector2>();
    }
}

Rebinding

public void StartRebinding(InputAction action)
{
    action.PerformInteractiveRebinding()
        .WithControlsExcluding("Mouse")
        .OnComplete(operation => {
            operation.Dispose();
            SaveBindings();
        })
        .Start();
}

Best Practices

Use Input Action Assets over direct polling
Implement rebinding for accessibility
Test all supported devices
Handle device disconnection gracefully
Save custom bindings to PlayerPrefs
