This is obviously something you're trying to do, but this is surely in the wrong place.

Код:

public OnPlayerPickUpPickup(playerid, pickupid)
{
AddStaticPickup(19607, 2, 1506.3359, 1432.3585, 10.1191, 0);
return 1;
}

Also from your code, you have a OnPlayerEnterCheckpoint, and a OnPlayerPickupPickup, yet nowhere in the script did you actually make those checkpoints/pickups.

And what pickup you create, is created when someone picks up a pickup, so thus, it'll never turn up.
