Unity Input System Skill

New Input System configuration and implementation for Unity.

Overview

This skill provides capabilities for implementing Unity's New Input System, including action maps, device support, and cross-platform input handling.

Capabilities

Action Configuration

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

Device Support

Configure gamepad support
Implement keyboard/mouse handling
Set up touch controls
Handle XR controllers

Control Schemes

Define control schemes
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
