Use GetPlayerSpeed para checar se a velocidade й maior que 0.

PHP Code:

stock GetPlayerSpeed(playerid,bool:kmh) // by misco edit by gamer_z
{
    new Float:Vx,Float:Vy,Float:Vz,Float:rtn;
    if(IsPlayerInAnyVehicle(playerid)) GetVehicleVelocity(GetPlayerVehicleID(playerid),Vx,Vy,Vz); else GetPlayerVelocity(playerid,Vx,Vy,Vz);
    rtn = floatsqroot(Vx*Vx + Vy*Vy + Vz*Vz);
    return kmh?floatround(rtn * 100 * 1.63):floatround(rtn * 100);
} 


PHP Code:

GetPlayerSpeed(playerid, true)
