I can't call the Enhanced Input System in C++

Hi, I’m trying to add the Enhanced Input System to my code, but I’m having a problem.

I can call the functions necessary in Blueprints because it appears in the context browser, but when I try adding the necessary code to set up the process in C++ nothing appears.

I’m trying to add the following in the BeginPlay() function:
`
void ARobotCharacter::BeginPlay()
{
Super::BeginPlay();

if (APlayerController* PlayerController = Cast<APlayerController>(GetController())
	if (UEnhancedInputLocalPlayerSubsystem* Subsystem = ULocalPlayer::GetSubsystem<UEnhancedInputLocalPlayerSubsystem>(PlayerController))
		Sybsystem->AddMappingContext(MC_Controller, 0);

}
`
The error I’m encountering is that for some reason I can’t call the UEnhancedInputLocalPlayerSubsystem class or its functions.

Note: MC_Controller is my own mapping context

hi @MataLaCucaracha

I do not know if your code is correct, only i do see what looks like a typing error near the end of your code

Could you post the errors?

Don’t forget to add the Enhanced Input module in your ProjectName.Build.cs:

PublicDependencyModuleNames.AddRange(new string[] { "EnhancedInput" });

Thanks for the help. I recently had the same issue again but this time is because I forgot to include the header XD. But thanks, forgot to mark it as the solution.

With the cursor over the red squiggle what message does it show? When you build the project does it shows any errors? Which IDE are you using?
