Unity) Input System (from : Unity Technologies)

Input System (from : Unity Technologies)

Unity 버전 2019.1 이상 버전에서 사용이 가능하다. 기존의 Input과 다르게 좀더 간편해 졌다고 해서

이번에 사용하게 되었다.

 

Unity Blog 설명으로는 다음과 같다.

'기존의 입력 시스템이 사용자 친화적이지 않으며 때로는 파일을 실행한 후 컨트롤러를 연결을 처리하는 것도 원할하지 않다는 것을 알게 되어서 완전히 새로 구축하게 되었다.`

 

Package Manager에서 Input System을 설치한다.

새로운 입력 시스템을 사용하려면 설정을 변경해야 한다.

Project Setting -> Player-> Active Input Handling 값을 변경해줘야 한다.

여러가지 방법으로 Input System을 처리할 수 있다.

 

< 코드에서 직접 처리 방식>

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    public GameObject Player;
    bool player_dead;
    void Update()
    {
       if (Mouse.current.leftButton.wasPressedThisFrame) // returns true when the mouse left button is pressed
      {
            Vector3 mousePos = Mouse.current.position.ReadValue();   
            mousePos.z=Camera.main.nearClipPlane;
            Vector3 Worldpos=Camera.main.ScreenToWorldPoint(mousePos);  
            if(player_dead)
           {
                 Instantiate(Player, Worldpos, Quaternion.identity);
           }
       }
    }
}

 

<스크립트 인스펙터(Insepctor) 바인딩>

using UnityEngine;
using UnityEngine.InputSystem;

// Using embedded actions with callbacks or reading values each frame.

public class ExampleScript : MonoBehaviour
{
    // these embedded actions are configurable in the inspector:
    public InputAction moveAction;
    public InputAction jumpAction;

    public void Awake()
    {
        // assign a callback for the "jump" action.
        jumpAction.performed += ctx => { OnJump(ctx); };
    }

    public void Update()
    {
        // read the value for the "move" action each frame.
        Vector2 moveAmount = moveAction.ReadValue<Vector2>();
    }

    public void OnJump(InputAction.CallbackContext context)
    {
        // jump code goes here.
    }

    // the actions must be enabled and disabled
    // when the GameObject is enabled or disabled

    public void OnEnable()
    {
        moveAction.Enable();
        jumpAction.Enable();
    }

    public void OnDisable()
    {
        moveAction.Disable();
        jumpAction.Disable();
    }
}
