Error 022: lvalue is not constant - damian123 - 26.09.2013

pawn Code:

stock GetClosestCar(playerid, exception = INVALID_VEHICLE_ID) {

    new
        Float: Distance,
        target = -1,
        Float: vPos[3];

    if(!IsPlayerInAnyVehicle(playerid)) GetPlayerPos(playerid, vPos[0], vPos[1], vPos[2]);
    else GetVehiclePos(GetPlayerVehicleID(playerid), vPos[0], vPos[1], vPos[2]);

    for(new v; v < MAX_VEHICLES; v++) if(GetVehicleModel(v) >= 400) {
        if(v != exception && (target < 0 || Distance > GetDistanceToCar(playerid, v, vPos[0], vPos[1], vPos[2]))) {
            target = v;
            Distance = GetDistanceToCar(playerid, v, vPos[0], vPos[1], vPos[2]); // Before the rewrite, we'd be running GetPlayerPos 2000 times...
        }
    }
    return target;
}

First of all, could you tell us which is the exact line of that error, second of all, why did you put return target which is defined to -1? Return should be 0 (False) or 1 (True).

Read the function's name, please.

GetClosestCar

It gets the closest car from a player. It returns the vehicleid, or if vehicles do not exist in the server, it returns -1.

@damian123: By the way, the distance should be less not greater.
