before you go around writing rubbish let me explain my old release had some glitches while It took me awhile to get this working It is still but it was way better then how it was written as the old version was totally wrong and inaccuracy, I don't know how prefect is this but it was based on Vana which the developer said it is quite accuracy, now if you wish to improve this you can go ahead and respect the decision that I have actually release this as it took me countless of effort to get this working.Code:public static byte[] moveMonster(int oid, boolean skillPossible, byte rawAction, byte skill, byte level, short option, Point startPos, List<LifeMovementFragment> moves) { final MaplePacketLittleEndianWriter mplew = new MaplePacketLittleEndianWriter(); mplew.writeShort(SendOpcode.MOVE_MONSTER.getValue()); mplew.writeInt(oid); mplew.writeBool(skillPossible); mplew.write(rawAction); mplew.write(skill); mplew.write(level); mplew.writeShort(option); mplew.writePos(startPos); serializeMovementList(mplew, moves); return mplew.getPacket(); }
