Unity进阶--对象池数据场景管理器笔记

泛型单例类

using System.Collections;
using System.Collections.Generic;public abstract class ManagersSingle<T> where T : new()
{private static T instance;// 获取单例实例public static T Instance{get{if (instance == null){instance = new T();}return instance;}}
}

泛型单例类（不带组件版）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class MyrSingletonBase<T> : MonoBehaviour where T : MonoBehaviour
{private static T instance;public static T Instance {get{return instance;}}protected virtual void Awake() {instance = this as T;}protected virtual void OnDestroy() {instance = null;}
}

对象池管理器

using System.Collections;
using System.Collections.Generic;
using UnityEngine;//对象池
public class PoolStack{//对象集合public Stack <UnityEngine.Object> stack = new Stack<Object>();//个数public int MaxCount = 100;//把游戏物体放入对象池public void Push(UnityEngine.Object go){if (stack.Count < MaxCount) stack.Push(go);else  GameObject.Destroy(go);}//从对象池取出对象public UnityEngine.Object Pop() {if (stack.Count > 0) return stack.Pop();return null;  }//清空池public void Clear(){foreach (UnityEngine.Object go in stack) GameObject.Destroy(go);stack.Clear();}}public class PoolManager :ManagersSingle<PoolManager>
{//管理多个池子Dictionary<string, PoolStack> poolDic = new Dictionary<string, PoolStack>();//从对象池取出对象，没有则创建一个public UnityEngine.Object Spawn(string poolName, UnityEngine.Object prefab){//如果没有对应的池子，创建池子if (!poolDic.ContainsKey(poolName)) poolDic.Add(poolName, new PoolStack());//从池子中拿出一个UnityEngine.Object go = poolDic[poolName].Pop();if (go == null) go = GameObject.Instantiate(prefab);return go;}//清空对象池public void UnSpawn(string poolName){if (poolDic.ContainsKey(poolName)){poolDic[poolName].Clear();poolDic.Remove(poolName);}}}

场景管理器

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;public class SceneManager : MyrSingletonBase<SceneManager>
{//场景名称public List<string> sceneList = new List<string>();//当前场景public int CurrentIndex = 0;//当前场景索引private System.Action<float> currentAction;//当前加载场景对象private AsyncOperation operation;public void LoadScene(string sceneName, System.Action<float> action){currentAction = action;if (sceneList.Contains(sceneName)){//更新场景索引CurrentIndex = sceneList.IndexOf(sceneName);//加载场景operation = UnityEngine.SceneManagement.SceneManager.LoadSceneAsync(sceneName, UnityEngine.SceneManagement.LoadSceneMode.Single);}}void Update(){if (operation != null){currentAction(operation.progress);//场景加载完成if (operation.progress >= 1) operation = null;}}//加载上一个场景public void LoadPre(System.Action<float> action){CurrentIndex--;LoadScene(sceneList[CurrentIndex], action);}//加载上一个场景public void LoadNext(System.Action<float> action){CurrentIndex++;LoadScene(sceneList[CurrentIndex], action);}
}
