How to achieve this blueprint in c++?

Hello guys, I’m trying to achieve this blueprint in c++. I tried to make a class that inherits from ALevelScript but I can’t figure out how to do this.

I was actually asking about the 'left mouse button ’ thing. The print string was just as an example

Here are the docs Input Docs

In your character you will extend or override the following in character.h/.cpp

void ACharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
	check(PlayerInputComponent);
}

by adding a call like (assuming you defined “Fire” in your project settings to include your left mouse button):

PlayerInputComponent->BindAction("Fire", IE_Pressed, this, &AYourCharacter::YourCharactersFireFunction);

This binds the generic input “Fire” to a function in your character class instance.
