public OnPlayerCommandText(playerid, cmdtext[])
{
	if (strcmp("/gotoallsaints", cmdtext, true, 10) == 0)
	{
	        SetPlayerPos(playerid,1201.29,-1325.50,13.40);
		SendClientMessage(playerid, COLOR_GREY, "You have been teleported to All Saints General Hospital (Los Santos)");
		return 1;
	}
	return 0;
}
