This is what I did when my gun wouldn't fire after the 1st compile using 4.19.2



Hi all

When I moved my PlayerInputComponent->BindAction(“Fire”, IE_Pressed, Gun, &AGun::OnFire);
out into the void AFirstPersonCharacter::BeginPlay()

it did not Fire so I took off Player form InputComponent->BindAction(“Fire”, IE_Pressed, Gun, &AGun::OnFire);

and it worked.

hope this helps someone
