Jump sound

Hi! Sorry for the late reply. Thank you! I tried to do something I got this:

Header:
void Landed(const FHitResult & Hit);
CPP:
void AGameCharacter::Landed(const FHitResult & Hit)
{
bIsJumping = false;
}

and it works, thank you! But can you check this part for correct syntax and etc.?

Thank you very much!
