Unity3D球沒有被刷卡

Question

我試圖用刷卡檢測來扔籃球。 根據滑動的長度將決定施加的力量（距離球被投擲。）GUI更新，所以我的滑動被檢測到，但籃球根本不動。我試着檢查運動學並取消檢查它，結果相同。 該腳本附加到我的相機。我將球對象拖入了由公共變量創建的對象和剛體位置。 這是我目前使用的代碼;

using UnityEngine; 
using System.Collections; 

public class NewBehaviourScript : MonoBehaviour 
{ 

    void Start() 
    { 

    } 

    private float length = 0; 
    private bool SW = false; 
    private Vector3 final; 
    private Vector3 startpos; 
    private Vector3 endpos; 

    public GameObject basketball; //Basketball Obj 
    public Rigidbody rbody;// Basketball Obj 

    void Update() 
    { 
     rbody = GetComponent<Rigidbody>(); 
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) 
     { 
      final = Vector3.zero; 
      length = 0; 
      SW = false; 
      Vector2 touchDeltaPosition = Input.GetTouch(0).position; 
      startpos = new Vector3(touchDeltaPosition.x, 0,    touchDeltaPosition.y); 
     } 
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) 
     { 
      SW = true; 
     } 

     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Canceled) 
     { 
      SW = false; 
     } 

     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Stationary) 
     { 
      SW = false; 
     } 
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended) 
     { 
      if (SW) 
      { 
       Vector2 touchPosition = Input.GetTouch(0).position; 
       endpos = new Vector3(touchPosition.x, 0, touchPosition.y); 
       final = endpos - startpos; 
       length = final.magnitude; 
       rbody.AddForce(new Vector3(touchPosition.x, 0, touchPosition.y)); 
      } 
     } 
    } 

    void OnGUI() 
    { 
     GUI.Box(new Rect(50, 300, 500, 30), "length: " + length); 
    } 
}

這可能是問題，rbody引用相機的剛體（如果有的話）

試試這個代碼，並確保籃球有一個剛體部件裝配！

void Update() 
    { 
     rbody = basketball.GetComponent<Rigidbody>(); 
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) 
     { 
      final = Vector3.zero; 
      length = 0; 
      SW = false; 
      Vector2 touchDeltaPosition = Input.GetTouch(0).position; 
      startpos = new Vector3(touchDeltaPosition.x, 0,    touchDeltaPosition.y); 
     } 
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) 
     { 
      SW = true; 
     } 

     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Canceled) 
     { 
      SW = false; 
     } 

     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Stationary) 
     { 
      SW = false; 
     } 
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended) 
     { 
      if (SW) 
      { 
       Vector2 touchPosition = Input.GetTouch(0).position; 
       endpos = new Vector3(touchPosition.x, 0, touchPosition.y); 
       final = endpos - startpos; 
       length = final.magnitude; 
       rbody.AddForce(new Vector3(touchPosition.x, touchPosition.x +touchPosition.y, touchPosition.y)); 
      } 
     } 
    }
