举例定义一个 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 thenif parent thenreturn CS.UnityEngine.GameObject.Instantiate(self.result, parent, worldStaytrue)elsereturn CS.UnityEngine.GameObject.Instantiate(self.result)endend
endreturn PrefabLoader设计思路
引入了各种资源加载器如AssetLoader、PrefabLoader等这些加载器负责加载不同类型的资源。 initialize方法调用onInit方法进行初始化。onInit方法中首先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方法进行异步加载。 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繁创建和销毁提高性能。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一致性和效率。
