[POMOC] OnPlayerEnterRaceCheckpoint

E ovako,dodao sam u modu:

public OnPlayerEnterRaceCheckpoint(playerid)
{
	return 1;
}

Ali kad kompiliram,izbaci mi error u kome pise da je OnPlayerEnterRaceCheckpoint vec definisan,a nema ga nigde,samo taj jedan ima...

Nemas sta ti dodavat, to postoji..

Al ja nemam to u modu:

public OnPlayerEnterRaceCheckpoint(playerid)
{
	return 1;
}

Kako onda da dodam neki race?! Necu u OnPlayerEnterCheckpoint nego ocu u OnPlayerEnterRaceCheckpoint
