多个手指

同时拖动不同的对象我按照这个教程 https://www.youtube.com/watch?v=SrCUO46jcxk 多个手指

多点触控，它的工作。并尝试用多个手指同时在每个对象上添加拖动功能。这是我的按钮代码，我添加了一些代码，使它可以同时拖动每个对象，但它仅适用于单个对象。我试过所有相关的帖子和教程，但无法执行，请帮忙？

using System.Collections; 
using UnityEngine; 

public class Button : MonoBehaviour{ 

public Color defaultColour; 
public Color selectedColour; 
private Material mat; 

private Vector3 screenPoint; 
private Vector3 offset; 


void Start(){ 
    mat = GetComponent<Renderer>().material; 
} 

void OnTouchDown(){ 
    mat.color = selectedColour; 
    Debug.Log ("Touch Down"); 

    screenPoint = Camera.main.WorldToScreenPoint (transform.position); 
    offset = transform.position - Camera.main.ScreenToWorldPoint (new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z)); 


    } 

void OnTouchUp(){ 
    mat.color = defaultColour; 
    Debug.Log ("Touch Up"); 
} 

void OnTouchStay(){ 
    mat.color = selectedColour; 
    Debug.Log ("Touch Stay"); 

    Vector3 curScreenPoint = new Vector3 (Input.mousePosition.x, Input.mousePosition.y, screenPoint.z); 
    Vector3 curPosition = Camera.main.ScreenToWorldPoint (curScreenPoint) + offset; 
    transform.position = curPosition; 


} 

void OnTouchExit(){ 
    mat.color = defaultColour; 
    Debug.Log ("Touch Exit"); 
} 
}

该代码可用于输入触控功能

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 

public class TouchInput : MonoBehaviour { 

    public LayerMask touchInputMask; 
    private static List<GameObject> touchList = new List<GameObject>(); 
    private GameObject[] touchesOld; 
    private RaycastHit hit; 



    void Update() { 

     #if UNITY_EDITOR 
     if(Input.GetMouseButton(0) || Input.GetMouseButtonDown(0) || Input.GetMouseButtonUp(0)){ 
      touchesOld = new GameObject[touchList.Count]; 
      touchList.CopyTo(touchesOld); 
      touchList.Clear(); 

      Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); 
      if(Physics.Raycast(ray, out hit, touchInputMask)){ 
       GameObject recipient = hit.transform.gameObject; 
       touchList.Add(recipient); 

       if (Input.GetMouseButtonDown(0)){ 
        recipient.SendMessage("OnTouchDown",hit.point,SendMessageOptions.DontRequireReceiver); 

       } 
       if (Input.GetMouseButtonUp(0)){ 
        recipient.SendMessage("OnTouchUp",hit.point,SendMessageOptions.DontRequireReceiver); 

       } 
       if (Input.GetMouseButton(0)){ 
        recipient.SendMessage("OnTouchStay",hit.point,SendMessageOptions.DontRequireReceiver); 



       } 

      } 

      foreach (GameObject g in touchesOld){ 
       if (!touchList.Contains(g)){ 
        g.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver); 
       } 
      } 
     } 

     #endif 


     if (Input.touchCount > 0){ 
      touchesOld = new GameObject[touchList.Count]; 
      touchList.CopyTo(touchesOld); 
      touchList.Clear(); 

      foreach (Touch touch in Input.touches){ 

       Ray ray = Camera.main.ScreenPointToRay (touch.position); 
       //RaycastHit hit; 

       if (Physics.Raycast(ray, out hit, touchInputMask)){ 
        GameObject recipient = hit.transform.gameObject; 
        touchList.Add(recipient); 

        if (touch.phase == TouchPhase.Began){ 
         recipient.SendMessage("OnTouchDown",hit.point,SendMessageOptions.DontRequireReceiver); 

        } 
        if (touch.phase == TouchPhase.Ended){ 
         recipient.SendMessage("OnTouchUp",hit.point,SendMessageOptions.DontRequireReceiver); 
        } 
        if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved){ 
         recipient.SendMessage("OnTouchStay",hit.point,SendMessageOptions.DontRequireReceiver); 


        } 
        if (touch.phase == TouchPhase.Canceled){ 
         recipient.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver); 
        } 
       } 
      } 
      foreach (GameObject g in touchesOld){ 
       if (!touchList.Contains(g)){ 
        g.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver); 
       } 
      } 
     } 
    }

现在终于完成这个过程中，我可以执行此过程有两种方式

使用touchScript库，它有丰富功能，我们可以一次拖动，旋转，翻译和缩放多个对象。 https://www.youtube.com/watch?v=HHLBJ1Ss2S0

注意：这是旧的视频，现在它改变了，但它几乎是相同的。 [TouchScript是免费资源商店用]

其他选项，附加下面的代码在空游戏物体或在相机中使用System.Collections中（添加标签层）

; using System.Collections.Generic; 使用UnityEngine;使用UnityEngine.UI的 ;

public struct objectst public Vector3 screenPoint; public Vector3 offset; }

公共类TOUCHINPUT：MonoBehaviour {

public LayerMask touchInputMask; 
private static List<GameObject> touchList = new List<GameObject>(); 
public static Dictionary<int,objectst> touchobjects = new Dictionary<int,objectst>(); 

private GameObject[] touchesOld; 
private RaycastHit hit; 
public Text Count, IndexLift; 

private Vector3 targetPos; 





void Update() { 


    int nbTouches = Input.touchCount; 

    if(nbTouches > 0) 
    { 
     nbTouches = 5; 

     print(nbTouches + " touch(es) detected"); 

     touchesOld = new GameObject[touchList.Count]; 
     touchList.CopyTo(touchesOld); 
     touchList.Clear(); 

     for (int i = 0; i < nbTouches ; i++) 
     { 


      Touch touch = Input.GetTouch(i); 


      print("Touch index " + touch.fingerId + " detected at position " + touch.position); 

      Ray ray = Camera.main.ScreenPointToRay (touch.position); 


      if (Physics.Raycast(ray, out hit, touchInputMask)){ 
       GameObject recipient = hit.transform.gameObject; 
       touchList.Add(recipient); 

       //recipient.; 

       if (touch.phase == TouchPhase.Began){ 

        objectst tempobj = new objectst(); 
        tempobj.screenPoint = Camera.main.WorldToScreenPoint (recipient.transform.position); 
        tempobj.offset = recipient.transform.position - Camera.main.ScreenToWorldPoint (new Vector3 (touch.position.x, touch.position.y, tempobj.screenPoint.z));   

        touchobjects.Add(touch.fingerId,tempobj); 




       } 

       if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved){ 


        Vector3 curScreenPoint = new Vector3 (touch.position.x, touch.position.y, 
         touchobjects[touch.fingerId].screenPoint.z); 
        Vector3 curPosition = Camera.main.ScreenToWorldPoint (curScreenPoint) + touchobjects[touch.fingerId].offset; 
        recipient.transform.position = curPosition; 



       } 
       if (touch.phase == TouchPhase.Ended){ 

        Vector3 curScreenPoint = new Vector3 (touch.position.x, touch.position.y, 
         touchobjects[touch.fingerId].screenPoint.z); 
        Vector3 curPosition = Camera.main.ScreenToWorldPoint (curScreenPoint) - touchobjects[touch.fingerId].offset; 
        recipient.transform.position = curPosition; 

       } 
       if (touch.phase == TouchPhase.Canceled){ 

       } 
      } 


     } 
     foreach (GameObject g in touchesOld){ 
      if (!touchList.Contains(g)){ 
       g.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver); 
     } 

    } 
    } 

}
