ピンチズームで個々のオブジェクトを拡大縮小する方法

Question

ピンチズーム用のこのスクリプトは見つかりましたが、これはカメラのズームインとズームアウトのためのスクリプトです。オブジェクトがより効果的に機能する方法を教えてください。私はキューブをスケールしたいだけで、キューブだけが同時に何もスケーリングされません。球体ならば球体のみに感謝します。それはせずに動作しません - オブジェクト衝突型加速器が取り付けられていなければならない： はここのコードです：

using UnityEngine; 
{ 
public float perspectiveZoomSpeed = 0.5f;  // The rate of change of the field of view in perspective mode. 
public float orthoZoomSpeed = 0.5f;  // The rate of change of the orthographic size in orthographic mode. 
void Update() 
{ 
    // If there are two touches on the device... 
    if (Input.touchCount == 2) 
    { 
     // Store both touches. 
     Touch touchZero = Input.GetTouch(0); 
     Touch touchOne = Input.GetTouch(1); 

     // Find the position in the previous frame of each touch. 
     Vector2 touchZeroPrevPos = touchZero.position - touchZero.deltaPosition; 
     Vector2 touchOnePrevPos = touchOne.position - touchOne.deltaPosition; 

     // Find the magnitude of the vector (the distance) between the touches in each frame. 
     float prevTouchDeltaMag = (touchZeroPrevPos - touchOnePrevPos).magnitude; 
     float touchDeltaMag = (touchZero.position - touchOne.position).magnitude; 

     // Find the difference in the distances between each frame. 
     float deltaMagnitudeDiff = prevTouchDeltaMag - touchDeltaMag; 

     // If the camera is orthographic... 
     if (camera.isOrthoGraphic) 
     { 
      // ... change the orthographic size based on the change in distance between the touches. 
      camera.orthographicSize += deltaMagnitudeDiff * orthoZoomSpeed; 

      // Make sure the orthographic size never drops below zero. 
      camera.orthographicSize = Mathf.Max(camera.orthographicSize, 0.1f); 
     } 
     else 
     { 
      // Otherwise change the field of view based on the change in distance between the touches. 
      camera.fieldOfView += deltaMagnitudeDiff * perspectiveZoomSpeed; 

      // Clamp the field of view to make sure it's between 0 and 180. 
      camera.fieldOfView = Mathf.Clamp(camera.fieldOfView, 0.1f, 179.9f); 
     } 
    } 
} 
}

は、[OK]を、ので、私はそれを適切ので、そこにおそらくいくつかのバグをテストすることはできませんが、ここでのコードのための一般的な考え方です：

重要なのはそれは

using UnityEngine; 
using System.Collections; 
public class ObjectScalling : MonoBehaviour { 

private GameObject selectedObject;  
//public GameObject gameobject; 
// Update is called once per frame 
void Update() { 

    if (Input.touchCount == 0) 
    { 
     Touch touch = Input.touches[0]; 
     Ray ray = Camera.main.ScreenPointToRay(touch.position); 
     RaycastHit hit; 

     if (Physics.Raycast(ray, out hit, 100f)) 
     { 
      selectedObject = hit.collider.gameObject; 
     } 
    } 
    if (Input.touchCount == 2) 
    { 
     // Store both touches. 
     Touch touchZero = Input.GetTouch(0); 
     Touch touchOne = Input.GetTouch(1); 

     // Find the position in the previous frame of each touch. 
     Vector2 touchZeroPrevPos = touchZero.position - touchZero.deltaPosition; 
     Vector2 touchOnePrevPos = touchOne.position - touchOne.deltaPosition; 

     // Find the magnitude of the vector (the distance) between the touches in each frame. 
     float prevTouchDeltaMag = (touchZeroPrevPos - touchOnePrevPos).magnitude; 
     float touchDeltaMag = (touchZero.position - touchOne.position).magnitude; 

     // Find the difference in the distances between each frame. 
     float deltaMagnitudeDiff = prevTouchDeltaMag - touchDeltaMag; 

     selectedObject.transform.localScale = new Vector3(deltaMagnitudeDiff , deltaMagnitudeDiff , deltaMagnitudeDiff); 

    } 
} 
} 

それはおそらくいくつかのバグが含まれていますが、一般的に、あなたはすべてが、この行を除いて、あなたのUpdate()に入るもちろんその:)での作業を開始することがあります。deltaMagnitudeDiff
