Unity3d中的游戏用c语言中的鼠标缩放对象

Question

我正在用C＃在unity3d中制作游戏

我希望能够通过使用鼠标左键单击来减小对象，并通过鼠标右键来增大对象。 此代码的问题是：1.除非按比例放大，否则不允许按比例缩小2.如果有多个obj，则一旦单击它们，它们都会受到影响。 我尝试了几种不同的方法来做，但我猜想这与调整布尔值有关。 非常感谢您的帮助

using UnityEngine;
using System.Collections;

public class Scale : MonoBehaviour 
{
    public GameObject obj;

    private float targetScale;
    public float maxScale = 10.0f;
    public float minScale = 2.0f;

    public float shrinkSpeed = 1.0f;

    private bool resizing = false;


void OnMouseDown()
    {
        resizing = true;

    }

    void Update()
    {
        if (resizing)
        {
             if (Input.GetMouseButtonDown(1)) 
            {
                targetScale = maxScale;


            }
             if (Input.GetMouseButtonDown(0))
            {
                targetScale = minScale;


            }

            obj.transform.localScale = Vector3.Lerp(obj.transform.localScale, new Vector3(targetScale, targetScale, targetScale), Time.deltaTime*shrinkSpeed);

            Debug.Log(obj.transform.localScale);

            if (obj.transform.localScale.x == targetScale)
            {
            resizing = false;
                Debug.Log(resizing);
            }
    }
    }
}

使用UnityEngine; 使用System.Collections;

公共课等级：MonoBehaviour {

public float maxScale = 10.0f;
public float minScale = 2.0f;
public float shrinkSpeed = 1.0f;   

private float targetScale;
private Vector3 v3Scale;

void Start() {
   v3Scale = transform.localScale;   
}

void Update()
{
   RaycastHit hit;
   Ray ray;

   if (Input.GetMouseButtonDown (0)) {
     ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     if (Physics.Raycast(ray, out hit) && hit.transform == transform) {
      targetScale = minScale;
      v3Scale = new Vector3(targetScale, targetScale, targetScale);
     }

   }

   if (Input.GetMouseButtonDown (1)) {
     ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     if (Physics.Raycast(ray, out hit) && hit.transform == transform) {
      targetScale = maxScale;
      v3Scale = new Vector3(targetScale, targetScale, targetScale);
     }
   }

   transform.localScale = Vector3.Lerp(transform.localScale, v3Scale, Time.deltaTime*shrinkSpeed);
}

}
