菜单栏相关：ENABLE_DLL选项
ET->ChangeDefine->ADD_ENABLE_DLL/REMOVE_ENABLE_DLL
一般在开发阶段使用Editor时需要关闭ENABLE_DLL选项。该选项关闭时，修改脚本之后，会直接重新编译所有的代码，Editor在运行时会直接使用最新的程序集。如果ENABLE_DLL选项是开启的，框架启动后会加载之前生成的程序集文件（这个文件需要在ET->BuildTool界面生成），导致每次需要应用修改，都要重新生成程序集文件。
框架解析
框架入口解析
启动流程如下
入口文件为Init，之后调用CodeLoader对代码进行加载
如果不是EnableDll模式则直接加载程序集。否则通过AB加载文件，之后调用LoadHotfix函数
LoadHotfix会加载程序集，并且调用EventSystem，根据特性注册对应事件的监听。
之后调用ET.Entry的Start方法。
ET.Entry.Start 进行初始化之后，调用FiberManager.Instance.Create调用FiberInit事件，推送对应的EntryEvent事件
推送EntryEvent3，EntryEvent3_InitClient接收后推送AppStartInitFinish
AppStartInitFinish_CreateLoginUI接收该事件后，创建UI场景
UI系统
UI界面的生成流程
ET是通过异步方式创建UI，如下方例子，调用UIHelper.Create方法，指定创建UI的场景，UI类型和对应的层级
protected override async ETTask Run(Scene scene, EventType.AppStartInitFinish args){await UIHelper.Create(scene, UIType.UILogin, UILayer.Mid);}调用scene挂载的UIComponent组件，处理Create事件
public static async ETTask<UI> Create(Scene scene, string uiType, UILayer uiLayer){return await scene.GetComponent<UIComponent>().Create(uiType, uiLayer);}之后会标记有对应UIEvent特性的类，处理该事件，开始加载资源并生成对应的GameObject
[UIEvent(UIType.UILogin)]public class UILoginEvent: AUIEvent{public override async ETTask<UI> OnCreate(UIComponent uiComponent, UILayer uiLayer){await uiComponent.DomainScene().GetComponent<ResourcesLoaderComponent>().LoadAsync(UIType.UILogin.StringToAB());GameObject bundleGameObject = (GameObject) ResourcesComponent.Instance.GetAsset(UIType.UILogin.StringToAB(), UIType.UILogin);GameObject gameObject = UnityEngine.Object.Instantiate(bundleGameObject, UIEventComponent.Instance.GetLayer((int)uiLayer));UI ui = uiComponent.AddChild<UI, string, GameObject>(UIType.UILogin, gameObject);ui.AddComponent<UILoginComponent>();return ui;}public override void OnRemove(UIComponent uiComponent){ResourcesComponent.Instance.UnloadBundle(UIType.UILogin.StringToAB());}}
UI组件解析
以UILogin为例子，对应的Prefab实际上只挂载了ReferenceCollector，ReferenceCollector负责将结点进行绑定
生成该GameObject之后，调用AddComponent
[UIEvent(UIType.UILogin)]public class UILoginEvent: AUIEvent{public override async ETTask<UI> OnCreate(UIComponent uiComponent, UILayer uiLayer){string assetsName = $"Assets/Bundles/UI/Demo/{UIType.UILogin}.prefab";GameObject bundleGameObject = await uiComponent.Scene().GetComponent<ResourcesLoaderComponent>().LoadAssetAsync<GameObject>(assetsName);GameObject gameObject = UnityEngine.Object.Instantiate(bundleGameObject, uiComponent.UIGlobalComponent.GetLayer((int)uiLayer));UI ui = uiComponent.AddChild<UI, string, GameObject>(UIType.UILogin, gameObject);ui.AddComponent<UILoginComponent>();return ui;}public override void OnRemove(UIComponent uiComponent){}}其中UILoginComponent负责显示对应成员
[ComponentOf(typeof(UI))]
public class UILoginComponent: Entity, IAwake
{public GameObject account;public GameObject password;public GameObject loginBtn;
}AddComponent之后，会调用对应的System，这里UILoginComponentSystem就是对应的System，在Awake阶段通过ReferenceCollector对UILoginComponent进行了绑定，以及实现了对应的UI逻辑
[ObjectSystem]
public class UILoginComponentAwakeSystem : AwakeSystem<UILoginComponent>
{protected override void Awake(UILoginComponent self){ReferenceCollector rc = self.GetParent<UI>().GameObject.GetComponent<ReferenceCollector>();self.loginBtn = rc.Get<GameObject>("LoginBtn");self.loginBtn.GetComponent<Button>().onClick.AddListener(()=> { self.OnLogin(); });self.account = rc.Get<GameObject>("Account");self.password = rc.Get<GameObject>("Password");}
}场景切换
关于ET的场景切换相关逻辑可以查看
UILobbyComponentSystem处理进入Map的操作，先是调用EnterMap异步函数，等待EnterMapHelper异步返回后删除界面
//UILobbyComponentSystempublic static async ETTask EnterMap(this UILobbyComponent self){await EnterMapHelper.EnterMapAsync(self.ClientScene());await UIHelper.Remove(self.ClientScene(), UIType.UILobby);}之后EnterMapHelper会向服务器发起进入Map的请求
//EnterMapHelperpublic static async ETTask EnterMapAsync(Scene clientScene){try{G2C_EnterMap g2CEnterMap = await clientScene.GetComponent<SessionComponent>().Session.Call(new C2G_EnterMap()) as G2C_EnterMap;clientScene.GetComponent<PlayerComponent>().MyId = g2CEnterMap.MyId;// 等待场景切换完成await clientScene.GetComponent<ObjectWait>().Wait<Wait_SceneChangeFinish>();EventSystem.Instance.Publish(clientScene, new EventType.EnterMapFinish());}catch (Exception e){Log.Error(e);} }
