触摸和拖动问题Unity 2D游戏

Question

我的触摸控件存在一些问题。

1）我的游戏是2D。当我在我的Android设备上测试它时，当从右触摸移动到左触摸时，2D图像几乎消失。该对象被视为3D对象。我认为这与Z空间有关。

2）如何让角色像这个视频一样移动 - https://www.youtube.com/watch?v=5hckY75j_lg。在这种情况下，您触摸屏幕的任何地方都会抓住玩家（头部），并且与手指完全一样移动。

任何帮助都会受到赞赏！

这是我的代码：

公共类TouchLogic：MonoBehaviour {

 public static int currTouch = 0;
 private Ray ray;
 private RaycastHit rayHitInfo = new RaycastHit ();
 [HideInInspector ]
 public int touch2Watch=64;

 // Update is called once per frame
 void Update () {
     if (Input.touches.Length <= 0) {
     } else {
         for (int i = 0; i < Input.touchCount; i++) {
             currTouch = i;
             if (this.GetComponent <GUITexture >() != null && (this.GetComponent <GUITexture >().HitTest (Input.GetTouch (i).position))) {
                 if (Input.GetTouch (i).phase == TouchPhase.Began) {
                     this.SendMessage ("OnTouchBegan");
                 }
                 if (Input.GetTouch (i).phase == TouchPhase.Ended ) {
                     this.SendMessage ("OnTouchEnded");
                 }    
                 if (Input.GetTouch (i).phase == TouchPhase.Moved ) {
                     this.SendMessage ("OnTouchMoved");
                 }
             }
             ray = Camera.main.ScreenPointToRay (Input.GetTouch (i).position);
             switch (Input.GetTouch (i).phase) {
             case TouchPhase .Began:
                 this.SendMessage ("OnTouchBeganAnywhere");
                 if (Physics.Raycast (ray, out rayHitInfo))
                     rayHitInfo.transform.gameObject.SendMessage ("OnTouchBegan2D");
                 break;
             case TouchPhase .Ended :
                 this.SendMessage ("OnTouchEndedAnywhere");
                 if (Physics.Raycast (ray, out rayHitInfo))
                     rayHitInfo.transform.gameObject.SendMessage ("OnTouchEnded2D");
                 break;
             case TouchPhase .Moved :
                 this.SendMessage ("OnTouchMovedAnywhere");
                 if (Physics.Raycast (ray, out rayHitInfo))
                     rayHitInfo.transform.gameObject.SendMessage ("OnTouchMoved2D");
                 break;
             case TouchPhase .Stationary :
                 this.SendMessage ("OnTouchStayedAnywhere");
                 if (Physics.Raycast (ray, out rayHitInfo))
                     rayHitInfo.transform.gameObject.SendMessage ("OnTouchStayed2D");
                 break;
             }
         }
     }
 }

如果您正在制作2D游戏，则必须使用

Vector3.up

而不是

Vector3.forward
