I am trying to make a local co-op game… My goal here is to have more than 1 player using different controllers… or different keys on the keyboard.
I have the following Load Players function:
void AGeneralGameMode::LoadPlayers()
{
// There is no point in running this loop if MaxPlayers is not set
if (GetMaxPlayerCount())
{
for (int32 a = 1; a <= GetMaxPlayerCount(); a++)
{
UWorld* currentWorld = GetWorld();
ABasePlayer* newPlayer = ABasePlayer::Instantiate(currentWorld);
FString actorName = FString::Printf(TEXT("Player%dStart"), a);
APlayerStart* playerStart = ActorHelper::FindActorsByTypeAndName<APlayerStart>(currentWorld, actorName);
if (playerStart != NULL)
{
SetupPlayerModel* setupPlayerModel = new SetupPlayerModel();
setupPlayerModel->PlayerStart = playerStart;
setupPlayerModel->PlayerNumber = a;
newPlayer->Setup(setupPlayerModel);
ABasePlayerController* newController = currentWorld->SpawnActor<ABasePlayerController>(ABasePlayerController::StaticClass());
if (newController)
{
currentWorld->AddController(newController);
newController->Possess(newPlayer);
newController->GetPawn()->Restart();
}
Players.Add(newPlayer);
}
else
{
throw FString::Printf(TEXT("You are searching for a Player%dStart but it could not be found"), a);
}
}
}
else
{
throw "MaxPlayers was not set";
}
}
- I first get the world
- Then i create a new ABasePlayer (which is APlayerCharacter)
- Then i go find the APlayerStart actors in my map
- Then i place the player start into a SetupPlayerModel
- Then i create a new ABasePlayerController which is APlayerController
- Finally I AddController to the current world, Possess the player and restart the player’s pawn.
Here is my ABasePlayer:
void ABasePlayer::Setup(SetupPlayerModel* setupPlayerModel)
{
this->setupPlayerModel = setupPlayerModel;
// Set up player starting position
FVector location = setupPlayerModel->PlayerStart->GetActorLocation();
SetActorLocation(location);
if (GEngine)
{
//Debug line shows up
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Blue, FString::SanitizeFloat(GetActorRotation().Yaw));
}
}
void ABasePlayer::Init()
{
Score = new BaseScore();
}
bool ABasePlayer::IsActive()
{
return Active;
}
void ABasePlayer::SetAsActive()
{
Active = true;
}
void ABasePlayer::Deactivate()
{
Active = false;
}
BaseScore& ABasePlayer::GetScore()
{
return *Score;
}
void ABasePlayer::SetupPlayerInputComponent(class UInputComponent* InputComponent)
{
// set up gameplay key bindings
InputComponent->BindAxis(*FString::Printf(TEXT("Player%dMoveRight"), setupPlayerModel->PlayerNumber), this, &ABasePlayer::MoveRight);
}
It inherits from the default APlayerCharacter you get when you first create a project… If you must see it, it looks like this: http://pastebin.com/3rWFgg5A
Finally, my input mappings look like this:
[/Script/Engine.InputSettings]
DefaultTouchInterface=/Engine/MobileResources/HUD/LeftVirtualJoystickOnly.LeftVirtualJoystickOnly
+ActionMappings=(ActionName="Jump", Key=W)
+ActionMappings=(ActionName="Jump", Key=Up)
+ActionMappings=(ActionName="Jump", Key=SpaceBar)
+ActionMappings=(ActionName="Jump", Key=Gamepad_FaceButton_Bottom)
+AxisMappings=(AxisName="MoveRight", Key=A, Scale=-1.f)
+AxisMappings=(AxisName="MoveRight", Key=D, Scale=1.f)
+AxisMappings=(AxisName="MoveRight", Key=Gamepad_LeftX, Scale=1.f)
+AxisMappings=(AxisName="Player1MoveRight", Key=A, Scale=-1.f)
+AxisMappings=(AxisName="Player1MoveRight", Key=D, Scale=1.f)
+AxisMappings=(AxisName="Player1MoveRight", Key=Gamepad_LeftX, Scale=1.f)
+AxisMappings=(AxisName="Player2MoveRight", Key=J, Scale=-1.f)
+AxisMappings=(AxisName="Player2MoveRight", Key=L, Scale=1.f)
+AxisMappings=(AxisName="Player2MoveRight", Key=Gamepad_LeftX, Scale=1.f)
I cannot understand why my players do not react to the keyboard…? Any ideas?
P.S GetMaxPlayerCount() returns 2.
It’s really hard to find example code for things you want to do with C++… All this blue print **** is useless to me.
