  TogglePlayerControllable(playerid, false);

  return 1;
  }

	return 1;
}

public OnPlayerDeath(playerid, killerid, reason)
{
	if(gPlayerUsingLoopingAnim[playerid]) {
		gPlayerUsingLoopingAnim[playerid] = 0;
	}

 	return 1;
}

i didn't test it though, tell me if it works. But i think you must do it as a filterscript
