Stepashka, ошибко

pawn Code:

ST[0] = floatsqroot(floatpower(ST[0], 2.0) + floatpower(ST[1], 2.0) + floatpower(ST[2], 2.0));
    return floatround(ST[3])*100;

я бы так сделал:

pawn Code:

stock GetPlayerSpeed(playerid)
{
    new Float:ST[3];
    if(IsPlayerInAnyVehicle(playerid))GetVehicleVelocity(GetPlayerVehicleID(playerid),ST[0],ST[1],ST[2]);
    else GetPlayerVelocity(playerid,ST[0],ST[1],ST[2]);
    return floatround( floatsqroot(floatpower(ST[0], 2.0) + floatpower(ST[1], 2.0) + floatpower(ST[2], 2.0)) )*100;
}
