# 前言
继承关系：BP_XXX_Base -> BP_Idol_Base -> TsIdolActor -> AVCharacter -> ACharacter 。
主要逻辑位于TsIdolActor中，文件路径为`Script/LiveDirector/Character/TsIdolActor.ts`

# AVCharacter
主要实现了`virtual void OnRep_AttachmentReplication() override;`，声明了若干BlueprintNativeEvent：
- bool CanSyncRelativeTransform();  
- void BeforeAttachToNewParent();  
- void AfterAttachToNewParent();
	
## OnRep_AttachmentReplication()
注释：
>// 动捕模式下，CanSync=false. 各端自行计算Actor Location, client无需使用Server计算结果  
  // 自由行走模式下, CanSync=true，client需要同步server的transform信息

# TsIdolActor.ts
## VirtualOverrider

```typescript
CanSyncRelativeTransform(): boolean {
	if (Utils.HasTag(this.PropTags, new UE.GameplayTag("Idol.AIACao"))) {
		return false;
	}
	if(this.MovementComp && this.MovementComp.ManulMovement){
		return false
	}
	var animInstance = this.Mesh.GetAnimInstance() as UE.IdolAnimInstance
	let fullbodyNode = Reflect.get(animInstance, 'AnimGraphNode_Fullbody') as UE.AnimNode_FullBody
	return !(fullbodyNode && fullbodyNode.bGetMotionData)
}
```
