Rep would be nice if this did help you =)
tought im on phone so if there is a mistake im sorry

EDIT:
If you need to create more than one checkpoints, you can use this instead:

Код:

public OnPlayerEnterCheckpoint(playerid)
{
	GivePlayerMoney(playerid, 1000);
	DisablePlayerCheckpoint(playerid);
        SetPlayerCheckpoint(playerid, NEW coordinates, 3.0);
	return 1;
}

OR if you're making checkpoints like in a race, you can use SetPlayerRaceCheckpoint
