1 - Set a timer that when a player is near that point, the checkpoint appears there(sometimes bugging).

2 - Or use pickups(Recommended).
Example(pickups):

Код:

new Pickup1;

public OnGamemodeInit()
{
  Pickup1 = CreatePickup(MODEL,TYPE,X,Y,Z); //
  return 1;
}

public OnPlayerPickUpPickup(playerid,pickupid)
{
  if(pickupid == Pickup1)
  {
    SetPlayerPos(...);//etc..
    [...]
    return 1;
  }
  return 0;
}
