【问题描述】：

我正在做一个挖泥游戏。有 2 个泥游戏对象（精灵）需要以正确的顺序挖掘。我为每个对象分配一个脚本。禁用 mud2 boxcollider 以防止它们移动，直到泥 1 被拖动以触发 L box collider 。但是当我尝试播放时，即使mud1没有触发L box collider，mud2仍然可以拖动。我还取消了mud2的box collider。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class pg7_mud1 : MonoBehaviour
{
   private Vector3 screenPoint;
   private Vector3 startPosition;

   public BoxCollider mud2;
   // Start is called before the first frame update
   void Start()
   {
       mud2.enabled = false;
   }

   // Update is called once per frame
   void Update()
   {
    
    
   }

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

   void OnMouseDrag()
   {
      Debug.Log("can drag");
       Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
       Vector3 curPosition = Camera.main.ScreenToWorldPoint (curScreenPoint);
       this.transform.position = new Vector3(curPosition.x, -5f, curPosition.z);  
   }

    void OnTriggerEnter(Collider other)
   {
       if(other.gameObject.name =="left-area")
       {   
           Debug.Log("touched edge");
           mud2.enabled = true;
       }
   }

【解决方案1】：

您可以尝试使用 Destroy(object, time) 方法而不是禁用碰撞器

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class pg7_mud1 : MonoBehaviour
{
   private Vector3 screenPoint;
   private Vector3 startPosition;

   public BoxCollider mud2;
   public gameObject mud2obj;
   // Start is called before the first frame update
   void Start()
   {
       destroy(mud2);
   }

   // Update is called once per frame
   void Update()
   {
    
    
   }

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

   void OnMouseDrag()
   {
      Debug.Log("can drag");
       Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
       Vector3 curPosition = Camera.main.ScreenToWorldPoint (curScreenPoint);
       this.transform.position = new Vector3(curPosition.x, -5f, curPosition.z);  
   }

    void OnTriggerEnter(Collider other)
   {
       if(other.gameObject.name =="left-area")
       {   
           Debug.Log("touched edge");
           mud2obj.AddComponent(typeof(BoxCollider));
       }
   }
