定义场景A与场景B，A=>B。
1. 创建一个和A或者B相同的场景道具。使用LevelInstance。
2. 制作渐变效果，在A或者B溶解完成后，进行一次切换区域。     
	1. 或者使用一个其他模型做过度。
3. 物理问题可以使用 Ignore Component Transform 来解决。

manager.LayerManager.EnterLevelArea(this.preset.LevelAreaPreset.UUID, manager.LevelSwitchType);

# 角色会隐藏问题解决
1. TsIdolControllerActor.ts中绑定了若干事件
```typescript
RegisterEventListener(): void 
{
	this.ListenerWrapper_SwitchLiveArea = (liveAreaUUID: UE.Guid) => { this.SwitchToLiveArea(liveAreaUUID) }
	this.ListenerWrapper_OnFinishCreateTmpArea = (liveAreaUUID: UE.Guid) => { this.RequireSwitchToLiveArea(liveAreaUUID) }
	this.ListenerWrapper_SceneChanged =  (levelName:string)=>{this.OnSceneChanged() };
	this.ListenerWrapper_BeforeSceneChanged = (levelName:string)=>{this.BeforeSceneChanged() };
	DirectorEventSystem.RegisterEventListener(this, DirectorEvent.OnFinishSwitchLiveAreaLocal, this.ListenerWrapper_SwitchLiveArea)
	DirectorEventSystem.RegisterEventListener(this, DirectorEvent.OnFinishSwitchSubLevelLocal,this.ListenerWrapper_SceneChanged)
	DirectorEventSystem.RegisterEventListener(this, DirectorEvent.BeforeSwitchLevel,this.ListenerWrapper_BeforeSceneChanged)
	DirectorEventSystem.RegisterEventListener(this, DirectorEvent.OnFinishCreateTmpLiveAreaLocal,this.ListenerWrapper_OnFinishCreateTmpArea)
}
```

- ListenerWrapper_SwitchLiveArea：角色移动到其他LiveArea的核心逻辑。
- ListenerWrapper_OnFinishCreateTmpArea：无逻辑。
- ListenerWrapper_SceneChanged：卸载所有道具？this.PropComp.OnSceneChanged()
- ListenerWrapper_BeforeSceneChanged：将角色与衣服从LiveAreaDetach? this.DressModel.K2_DetachFromActor()

## ListenerWrapper_SwitchLiveArea
```c++
    SwitchToLiveArea(TargetLiveAreaGUID: UE.Guid): void {
        console.warn(this.Identity.RootTag.TagName.toString() + ' switch to live area ' + TargetLiveAreaGUID.ToString())
        this.LiveAreaGIUD = TargetLiveAreaGUID
        this.SetTransformToLiveArea()
        if (this.PropComp.DressModel && this.PropComp.DressModel.MovementComp&&this.PropComp.DressModel.MovementComp.ManulMovement) {
            console.warn(this.PropComp.DressModel.GetName() + ' is in free move mode, will not teleport to new area!')
            return
        }
        var liveAreaMgr = LiveAreaUtils.GetLievAreaManagerInstance(this)
        if (liveAreaMgr && liveAreaMgr.IsTmpLiveArea(TargetLiveAreaGUID)) {
            // teleport to the target live area without fx
            this.PropComp.Teleport(TargetLiveAreaGUID)
        } else {
            this.PropComp.DressModelTeleport(TargetLiveAreaGUID)
        }
    }
```
