Unity transform.localScale 脚本更改所有具有脚本的游戏对象

Question

我有一个任务是创建一个益智游戏。到目前为止，我取得了相当不错的进步。目前，我已经制作了一个脚本，可以使用 E 和 Q 更改抓取对象的大小，并将其分配给玩家可以抓取的每个对象。

问题是当我按下 Q 和 E 时，它改变了屏幕上的每个对象，包括抓取的对象。

我该如何解决？请帮忙

这里是代码：

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(MeshCollider))]

public class MouseDragAndResizing: MonoBehaviour
{

private Vector3 screenPoint;
private Vector3 offset;

void OnMouseDown()
{
    screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);

    offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
}

void OnMouseDrag()
{
    Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);

    Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
    transform.position = curPosition;

}

void Update()
{ 
    if(Input.GetKeyDown(KeyCode.E) && transform.localScale.x < 3 && transform.localScale.y < 3 && transform.localScale.z < 3)
    {
        transform.localScale = transform.localScale + new Vector3(0.5f, 0.5f, 0.5f);
    }
    if (Input.GetKeyDown(KeyCode.Q) && transform.localScale.x > 0.5 && transform.localScale.y > 0.5 && transform.localScale.z > 0.5)
    {
        transform.localScale = transform.localScale + new Vector3(-0.5f, -0.5f, -0.5f);
    }
    else if (transform.localScale.x < 0.5 && transform.localScale.y < 0.5 && transform.localScale.z < 0.5)
    {
        transform.localScale = Vector3.zero;
    }
}

}

没有检查你的棋子是否被选中，所以每个棋子都在更新中移动的问题我考虑将您的代码更改为这样的 smth 以了解您实际要移动和拖动的是哪一块

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(MeshCollider))]

public class MouseDragAndResizing: MonoBehaviour
{

    private Vector3 screenPoint;
    private Vector3 offset;
    private bool selected;

    void OnMouseDown()
    {
        screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);

        offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
        selected = true;
    }

    void OnMouseUp
    {
        selected = false;
    }

    void OnMouseDrag()
    {
        Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);

        Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
        transform.position = curPosition;
    }

    void Update()
    { 
        if (!selected){
            return;
        }
        if(Input.GetKeyDown(KeyCode.E) && transform.localScale.x < 3 && transform.localScale.y < 3 && transform.localScale.z < 3)
        {
            transform.localScale = transform.localScale + new Vector3(0.5f, 0.5f, 0.5f);
        }
        if (Input.GetKeyDown(KeyCode.Q) && transform.localScale.x > 0.5 && transform.localScale.y > 0.5 && transform.localScale.z > 0.5)
        {
            transform.localScale = transform.localScale + new Vector3(-0.5f, -0.5f, -0.5f);
        }
        else if (transform.localScale.x < 0.5 && transform.localScale.y < 0.5 && transform.localScale.z < 0.5)
        {
            transform.localScale = Vector3.zero;
        }
    }
}
