如何在統一旋轉後將對象恢復到原始位置？

Question

我創建了一個項目，當我們觸摸它時，一個立方體就會旋轉。當用戶停止觸摸立方體時，我希望立方體返回其原始位置。下面我已經加入旋轉的立方體的源代碼：

using UnityEngine; 

using System.Collections; 

[RequireComponent(typeof(MeshRenderer))] 

public class dr : MonoBehaviour 
{ 

    #region ROTATE 
    private float _sensitivity = 1f; 
    private Vector3 _mouseReference; 
    private Vector3 _mouseOffset; 
    private Vector3 _rotation = Vector3.zero; 
    private bool _isRotating; 


    #endregion 

    void Update() 
    { 
     if(_isRotating) 
     { 
      // offset 
      _mouseOffset = (Input.mousePosition - _mouseReference); // apply rotation 
      _rotation.y = -(_mouseOffset.x + _mouseOffset.y) * _sensitivity; // rotate 
      gameObject.transform.Rotate(_rotation); // store new mouse position 
      _mouseReference = Input.mousePosition; 
     } 

    } 

    void OnMouseDown() 
    { 
     // rotating flag 
     _isRotating = true; 

     // store mouse position 
     _mouseReference = Input.mousePosition; 
    } 

    void OnMouseUp() 
    { 
     // rotating flag 
     _isRotating = false; 
    } 

} 

編輯的代碼： - 使用UnityEngine;使用System.Collections的 ;

[RequireComponent（typeof運算（MeshRenderer））]

公共類PT：MonoBehaviour {

#region ROTATE 
private float _sensitivity = 1f; 
private Vector3 _mouseReference; 
private Vector3 _mouseOffset; 
private Vector3 _rotation = Vector3.zero; 
private bool _isRotating; 
private Quaternion original; 


#endregion 
void start(){ 
    original = transform.rotation; 
} 

void Update() 
{ 
    if(_isRotating) 
    { 
     // offset 
     _mouseOffset = (Input.mousePosition - _mouseReference); // apply rotation 
     _rotation.y = -(_mouseOffset.x + _mouseOffset.y) * _sensitivity; // rotate 
     gameObject.transform.Rotate(_rotation); // store new mouse position 
     _mouseReference = Input.mousePosition; 
    } 

} 

public void OnMouseDown() 
{ 
    // rotating flag 
    _isRotating = true; 

    // store mouse position 
    _mouseReference = Input.mousePosition; 
} 

public void OnMouseUp() 
{ 
    // rotating flag 
    _isRotating = false; 
    transform.rotation = original; 
} 

}

「我嘗試轉動沙發的3D模型和迴歸它的起始旋轉。但如果我用這個代碼「每當我停止觸摸沙發，它變成**背面沙發」** 我希望它回到最初的腐爛通貨膨脹。 u can see initally this is how the sofa looks like and if i stopped touching it returns to its backside of sofa. i want it to return to its front side again if i stopped rotation

我想立方體要返回到原來的位置，當用戶停止 觸摸立方體

我不能確切地告訴你掙扎其中的這部分，但你可以簡單地在Start或Awake函數中獲取GameObject的位置，然後在調用OnMouseUp時將transform.position設置爲該值。

private Vector3 originalPos; 

void Start() 
{ 
    //Get the original position 
    originalPos = transform.position; 
} 

void OnMouseUp() 
{ 
    _isRotating = false; 
    //Reset GameObject to the original position 
    transform.position = originalPos; 
} 

編輯：

對於旋轉，它也是-同樣的事情。只需使用Quaternion和transform.rotation而不是Vector3和transform.position。

private Quaternion originalPos; 

void Start() 
{ 
    //Get the original rotation 
    originalPos = transform.rotation; 
} 

void OnMouseUp() 
{ 
    _isRotating = false; 
    //Reset GameObject to the original rotation 
    transform.rotation = originalPos; 
} 

你仍然需要納入到這一點從你的答案原來的代碼。如果這是你不能做的事情，那就考慮看Unity的腳本教程here。
