如何使用觸摸輸入拖動增強模型

Question

我已經在Vuforia Unity3d中使用了此腳本，但它的行爲很奇怪。

任何人都可以發佈腳本來拖動/移動/旋轉3D模型。

public class touchcontrol : MonoBehaviour { 
    // Use this for initialization 
    void Start() { 

    } 

    // Update is called once per frame 
    void Update() 
    { 

     if (Input.touchCount > 0) 
     { 
      Touch touch = Input.GetTouch(0); // get first touch since touch count is greater than zero 

      if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved) 
      { 
       // get the touch position from the screen touch to world point 
       Vector3 touchedPos = Camera.main.ScreenToWorldPoint(new Vector3(touch.position.x, touch.position.y, 10)); 
       // lerp and set the position of the current object to that of the touch, but smoothly over time. 
       transform.position = Vector3.Lerp(transform.position, touchedPos, Time.deltaTime); 
      } 
     } 
    } 
} 

Answer 1

您應該如果條件之外移動你的位置更新代碼如下 - 你想達到什麼

public class touchcontrol : MonoBehaviour { 

    public float moveSpeed = 1f; 
    private Vector3 touchedPos; 

    // Use this for initialization 
    void Start() { 
     touchedPos = transform.position; 
    } 

    // Update is called once per frame 
    void Update() 
    { 
     if (Input.touchCount > 0) 
     { 
      Touch touch = Input.GetTouch(0); // get first touch since touch count is greater than zero 

      if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved) 
      { 
       // get the touch position from the screen touch to world point 
       touchedPos = Camera.main.ScreenToWorldPoint(new Vector3(touch.position.x, touch.position.y, transform.position.z)); 
       // lerp and set the position of the current object to that of the touch, but smoothly over time. 
      } 
     } 
     transform.position = Vector3.Lerp(transform.position, touchedPos, Time.deltaTime * moveSpeed); 
    } 
}

很簡單，你可以不用編碼。您的問題已經有答案here。
