c# - Unity3d 中的游戏用 c 中的鼠标缩放对象

Question

我正在用 C# 用 unity3d 制作游戏

我希望能够通过用鼠标左键单击它来使对象变小，用鼠标右键单击它来使对象变大。这段代码的问题是： 1. 它不允许缩小，除非它被放大 2. 如果有多个 obj，一旦它们被点击，它们都会受到影响。我尝试了几种不同的方法来做到这一点，我猜这与 resize bool 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；

公共类规模：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);
}

}
