PHP код:

new AutoFix[MAX_PLAYERS];
public OnVehicleDamageStatusUpdate (vehicleid, playerid)
{
     if(AutoFix[playerid] == 1)
     {
          RepairVehicle(vehicleid);
     }
     return 1;
}
CMD:autofix(playerid,params[])
{
    switch(AutoFix[playerid])
    {
        case 0: AutoFix[playerid] = 1; SendClientMessage(playerid,-1,"Auto-Fixed Disabled !");
        case 1: AutoFix[playerid] = 0; SendClientMessage(playerid,-1,"Auto-Fixed Enabled !");
    }
    return 1;
}
