[Improvement™]

Since MidoTrick's script code is messed up by 3 things, I made a re-make of his script.
Credit's goes to him.

pawn Code:

///Somewhere on top of your script
new bool:HasVehicleGodmode[MAX_PLAYERS];


//Under OnGameModeInit
SetTimer("Actualize", 2000, true);


//Under your Command Godmode (ON)
HasVehicleGodmode[playerid] = true;

//Under your Command Godmode (OFF)
HasVehicleGodmode[playerid] = false;


//Somewhere between all the Callbacks (public's)
forward AutoR(playerid);
public AutoR(playerid)
{
    if(IsPlayerInAnyVehicle(playerid) && HasVehicleGodmode[playerid])
    {
        new vid = GetPlayerVehicleID(playerid);
        RepairVehicle(vid);
    }
    return 1;
}
