UE4 C++ 调用蓝图

参考地址：https://answers.unrealengine.com/questions/551613/spawn-actor-in-c.html

UClass* BlueprintClass = StaticLoadClass(UObject::StaticClass(), NULL, TEXT("/Game/Libraries/Blueprints/BP_GrabActor.BP_GrabActor_C"), NULL, LOAD_None, NULL);
			FActorSpawnParameters SpawnInfo;
			SpawnInfo.Owner = this;
			SpawnInfo.Instigator = Instigator;
			SpawnInfo.SpawnCollisionHandlingOverride = ESpawnActorCollisionHandlingMethod::AlwaysSpawn;
			FTransform TF = FTransform();
			GetWorld()->SpawnActor<AActor>(BlueprintClass, TF, SpawnInfo);

这个太有用了。
