Hey Guys,
i made a Speed boost, but if i press the Key ingame, nothing happens.
Can anyone correct it, please? =)

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
  	if (IsPlayerInAnyVehicle(playerid) && GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
 	{
  		if (newkeys & KEY_SUBMISSION)
		{
			new Float:xx, Float:xy, Float:xz;
			GetVehicleVelocity(GetPlayerVehicleID(playerid),xx, xy, xz);
			SetVehicleVelocity(GetPlayerVehicleID(playerid),x*5,y*5,z*5);
			return 1;
		}
		return 1;
	}
	return 1;
}
