仅带有此标签的统一触摸按钮

Question

所以我有一个统一的触摸脚本，用于在带有盒子对撞机的 2d 精灵上进行简单触摸：

    var platform : RuntimePlatform = Application.platform;

 function Update(){
     if(platform == RuntimePlatform.Android || platform == RuntimePlatform.IPhonePlayer){
         if(Input.touchCount > 0) {
             if(Input.GetTouch(0).phase == TouchPhase.Began){
                 checkTouch(Input.GetTouch(0).position);
             }
         }
     }else if(platform == RuntimePlatform.OSXEditor){
         if(Input.GetMouseButtonDown(0)) {
             checkTouch(Input.mousePosition);
         }
     }
 }

 function checkTouch(pos){
     var wp : Vector3 = Camera.main.ScreenToWorldPoint(pos);
     var touchPos : Vector2 = new Vector2(wp.x, wp.y);
     var hit = Physics2D.OverlapPoint(touchPos);

     if (hit){
         Debug.Log("touched");
     }
 }

但我希望当对象 clicked/touched 具有特定标签时 Debug.Log 会有所不同

你要的是System.Action.

public System.Action _action;
...

public void FutureAction()
{
    //Whatever you want this function to perform
}
...

//When you know the action that you want it to perform
_action = FutureAction;
...

//When you want to call this action, in your checkTouched function for example
if (hit.CompareTag("myTag"))
    _action(); //This will call whatever action was saved into the variable.

希望对您有所帮助！

编辑：我用 C# 编写了我的代码，但 javascript 中的等效代码会以类似的方式工作。
