UE4一個(gè)PlayerController控制多個(gè)Actor的問(wèn)題

UE4中，一個(gè)PlayerController同時(shí)只能控制一個(gè)Actor，如果要實(shí)現(xiàn)RTS游戲中的那種多個(gè)Actor同時(shí)移動(dòng)，需要Spawn出來(lái)多個(gè)Controller（PlayerController或者AIController等，具體看你需求），每個(gè)Controller去Possess一個(gè)Actor，然后通過(guò)控制這多個(gè)Controller來(lái)實(shí)現(xiàn)移動(dòng)。

如何創(chuàng)建PlayerController，這個(gè)帖子講了一種方式：
How do you place APlayerCharacter onto APlayerStart and take control?

			In CreateLocalPlayer's case, the call chain you're looking for is:  

			UGameInstance::CreateLocalPlayer  

			ULocalPlayer::SpawnPlayActor  

			UWorld::SpawnPlayActor  

			AGameMode::PostLogin  

			AGameMode::StartNewPlayer  

			AGameMode::RestartPlayer  

			AGameMode::GetDefaultPawnClassForController

			    {  

			        localPlayer = gameInstance->GetFirstGamePlayer();

			    PostLogin( localPlayer->PlayerController );  

			    currentWorld->SpawnPlayActor( localPlayer, ENetRole::ROLE_None, urlSpawn2, localPlayer->GetUniqueNetIdFromCachedControllerId(), spawnError );  

			    StartNewPlayer( localPlayer->PlayerController );  

			    RestartPlayer( localPlayer->PlayerController );  

			    /*ABasePlayer* playerActor = ( ABasePlayer* )GetDefaultPawnClassForController( localPlayer->PlayerController ); 

			    ABasePlayerController* playerController = ( ABasePlayerController* )localPlayer->PlayerController; 

			    playerController->SetUpInput( playerActor, a );*/
