lua 游戏架构之资源加载 LoaderManager (一)

界说一个 LoaderManager class，用于管理各种资源加载器。它使用了对象池（Object Pool）来优化资源加载器的创建和烧毁，从而提高性能
举例界说一个 PrefabLoader
--[[
Desc: 封装AAS的接口，加载Prefab
--]]

---@alias PrefabLoader.CompleteDelegate fun(obj:table, l:PrefabLoader) | fun(l:PrefabLoader)

---@class PrefabLoader : BaseLoader
---@field result CS.UnityEngine.GameObject
---@field callback PrefabLoader.CompleteDelegate
local PrefabLoader = SimpleClassUtil:class(require 'Topjoy.Engine.Resources.BaseLoader')

PrefabLoader.intType = CS.Topjoy.Base.ResourceManagement.ResourcesUtil.TypeInts.GameObject

---@overload fun(parent:CS.UnityEngine.Transform): CS.UnityEngine.GameObject | CS.UnityEngine.Object
---@overload fun(): CS.UnityEngine.GameObject | CS.UnityEngine.Object
---@param parent CS.UnityEngine.Transform
---@param worldStay boolean @默认false
---@return CS.UnityEngine.GameObject | CS.UnityEngine.Object
function PrefabLoader:instantiate(parent, worldStay)
if self.result then
   if parent then
         return CS.UnityEngine.GameObject.Instantiate(self.result, parent, worldStay==true)
   else
         return CS.UnityEngine.GameObject.Instantiate(self.result)
   end
end
end

return PrefabLoader

设计思绪：

[*]引入了各种资源加载器，如AssetLoader、PrefabLoader等，这些加载器负责加载差别类型的资源。
[*] initialize方法调用onInit方法举行初始化。onInit方法中，起首获取资源管理器实例，然后初始化各种资源加载器池，每个池子使用TablePool来管理对象池。
[*] PrefabLoader为例，创建了一个对象池，池子大小为16。当需要新的PrefabLoader实例时，会调用传入的函数创建一个新的PrefabLoader对象，并设置其释放函数为self._assetPool:releaseObj(1)
[*] loadAssetAsync方法用于异步加载资源。它从对象池中获取一个PrefabLoader实例，初始化它，并调用其loadAsync方法举行异步加载。
[*] release方法用于释放所有资源加载器池，并清理资源管理器实例。
注意事项

[*]对象池的使用：通过对象池管理资源加载器，可以减少对象的频仍创建和烧毁，提高性能。
[*]异步加载：资源加载方法（如loadAssetAsync）都是异步的，可以避免阻塞主线程。
[*]资源管理器：使用CS.Topjoy.Base.ResourceManagement.ResourceManager来管理资源加载，确保资源加载的同等性和效率。
