单列（写了池子pool）用list实现的方法， 与伪单例(写了池子zidianpool)，用字典实现的方法，可以存入不同，i名字的物体

Posted 2021-01-12 satanj

用字典写的池子，还用了伪单利

伪单利要找一个物体把脚本挂起来，get方法要挂在你要点击的butten上，set脚本要挂在需要调用出来的物体上
池子代码（用字典写的）：

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class zidianPool:MonoBehaviour//伪单列
 6 {
 7     public static zidianPool Instace;//公有静态接口
 8     private void Start()
 9     {
10         Instace = this;//生命周期内是咧
11     }
12 
13     //private static zidianPool instance;
14     //private zidianPool() { }
15     //public static zidianPool Instace
16     //{
17     //      get {
18     //        if (instance==null)
19     //        {
20     //            instance = new zidianPool();
21     //        }
22     //        return instance;
23     //    }
24     //}
25 
26     Dictionary<string,List<GameObject>> dir=new Dictionary<string,List<GameObject>>();//存放不同形状的物体
27     public GameObject ISget(string name)
28     {
29         GameObject go = null;//要拿出来的东西
30         if (dir.ContainsKey(name))//是否包含named的key
31         {
32             List<GameObject> list=dir[name];
33             if (list.Count>0)
34             {
35                 go = list[0];
36                 go.SetActive(true);
37                 list.RemoveAt(0);
38             }
39         }
40         if (go==null)//没有名字 或者list为空的时候
41         {
42             go=GameObject.Instantiate(Resources.Load(name)) as GameObject;
43             int index = go.name.IndexOf("(Clone)");
44             go.name = go.name.Substring(0, index);
45         }
46         return go;
47     }
48 
49     public void Isset(GameObject obj)
50     {
51         obj.SetActive(false);
52         if (dir.ContainsKey(obj.name))//字典里是否已经有包含的物体
53         {
54             dir[obj.name].Add(obj);
55 
56         }
57         else
58         {
59             List<GameObject> list = new List<GameObject>();
60             list.Add(obj);
61             dir[obj.name] = list;
62         }
63 
64      //   obj.transform.parent = GameObject.Find("panel").transform;
65     }
66 }

get方法的脚本，也就是把东西拿出：

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class getzidian : MonoBehaviour {
 6     string[] s = { "Capsule", "Sphere" };
 7     public void get()
 8     {
 9        GameObject gp= zidianPool.Instace.ISget(s[Random.Range(0,2)]);
10        gp.transform.position = new Vector3(0, 5, 0);
11     }
12 }

set的脚本，也就是存入：

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class setzidian : MonoBehaviour {
 6 
 7     // Use this for initialization
 8     void Start () {
 9         
10     }
11     
12     // Update is called once per frame
13     void Update () {
14         if (transform.position.y<-5)
15         {
16             zidianPool.Instace.Isset(gameObject);
17         }
18     }
19 }

 

 

用list写的单列，单利不需要挂脚本

池子的脚本代码：

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class pool {
 6 
 7     private static pool instance;
 8     private pool() { }
 9     public static pool Instance
10     {
11         get {
12             if (instance==null)
13             {
14                 instance = new pool();
15             }
16             return instance;
17         }
18     }
19     List<GameObject> listpool = new List<GameObject>();
20     public GameObject GetCube(string name)
21     {
22         Debug.Log("我在池子里");
23         GameObject go = null;
24         if (listpool.Count>0)
25         {
26             go = listpool[0];
27             go.SetActive(true);
28             listpool.RemoveAt(0);
29         }
30         if (go==null)
31         {
32             go = GameObject.Instantiate(Resources.Load(name)) as GameObject;
33             int index = go.name.IndexOf("(Clone)");
34             go.name = go.name.Substring(0, index);
35         }
36         return go;
37     }
38     public void setpool(GameObject obj)
39     {
40         obj.SetActive(false);
41         listpool.Add(obj);
42     }
43 }

getj脚本，拿出要存入的东西：

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class get : MonoBehaviour {
 6     GameObject obj;
 7     // Use this for initialization
 8     void Start () {
 9         
10     }
11     public void GetPool()
12     {
13        obj=  pool.Instance.GetCube("Cube");
14       obj.transform.position = new Vector3(0,5,0);
15     }
16     // Update is called once per frame
17     void Update () {
18         
19     }
20 }

set脚本，就是把东西存入里面：

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class set : MonoBehaviour {
 6 
 7     // Use this for initialization
 8     void Start () {
 9         
10     }
11     
12     // Update is called once per frame
13     void Update () {
14         if (gameObject.activeSelf)
15         {
16             if (transform.position.y < -5)
17             {
18                 pool.Instance.setpool(gameObject);
19             }
20         }
21     }
22 }
