因为是动态加载，所以不用在构造的时候去加载。这里再BeginPlay里加载。

加载StaticMesh等资源，就使用LoadObject<UStaticMesh>(nullptr,TEXT("Copy Reference"))

加载类资源，比如蓝图Actor类

就使用LoadClass<AActor>(this,TEXT("Copy Reference"))

但是同样要在最后一个字母后+_C

 TEXT("/Script/Engine.Blueprint'/Game/StarterContent/Blueprints/Blueprint_WallSconce.Blueprint_WallSconce_C'")

SetStaticMesh测试动态加载的模型是否能赋值

GetWorld()->SpawnActor<AActor>(UClass*,FVector::ZeroVector,FRotator::ZeroRotator);

使用生成物体的方式，测试类。
