Command problem - Baumann - 18.08.2013

Hey why i get this error with this code ?
PHP код:
CMD:sc(playerid, params[])
{
    new vehicle;
    new ID;// wait
    new Float:x,Float:y,Float:z;
    if(ClassPolice == 1)return SendClientMessage(playerid, 0xffffff, "You can't use it"); // 
    if(sscanf(params, "u", ID)) return SendClientMessage(playerid, 0xffffff, "Usage: /sc [playerid]");// 
    vehicle = GetPlayerVehicleID(playerid);
    if(GetVehicleVelocity(vehicle, x , y, z) > 50))
    {
        if(GetDistanceBetweenPlayers(playerid,ID)  < 12)
        {
            new pwlvl = GetPlayerWantedLevel(playerid);
            SetPlayerWantedLevel(playerid,pwlvl+1);
        }
    }
    return 1;
}
forward Float:GetDistanceBetweenPlayers(p1,p2);
public Float:GetDistanceBetweenPlayers(p1,p2)
{
    new Float:x1,Float:y1,Float:z1,Float:x2,Float:y2,Float:z2;
    if (!IsPlayerConnected(p1) || !IsPlayerConnected(p2))
    {
        return -1.00;
    }
    GetPlayerPos(p1,x1,y1,z1);
    GetPlayerPos(p2,x2,y2,z2);
    return floatsqroot(floatpower(floatabs(floatsub(x2,x1)),2)+floatpower(floatabs(floatsub(y2,y1)),2)+floatpower(floatabs(floatsub(z2,z1)),2));
}

if(GetVehicleVelocity(vehicle, x , y, z) > 50))
You get error because there's unmatched closing parenthesis at the end. Also that if statement won't work properly. GetVehicleVelocity function returns multiple values, the x, y and z velocities are stored in the referenced variables.

Re: Command problem - Baumann - 18.08.2013

i have already defined vehicle which will not give you errors or multiple values & yes if(GetVehicleVelocity(vehicle, x , y, z) > 50)) will not work properly ..

Re: Command problem - Edix - 18.08.2013

What he meant it that you have one extra ")" at the end of the "if" statement.

fix:
pawn Код:
if(GetVehicleVelocity(vehicle, x , y, z) > 50)
