[Request] Field Limits

BestSiteEvar · Mar 19, 2014

Anyone know where I can find field limit blocks? Like those little packets that blocks players from using skills in event maps except for GMs? I literally can't find it anywhere and GM's are treated like regular players and can't use any skills or movement speed boost in JQ/Event maps.

Here's one I found on field 910000000 (Free Market) in the v147.1 WZ files. Also, I'm pretty sure this belongs to the WZ section as it's client-sided.

Isn't there one in the source though? Something like a packet being sent every time a player enters an event map or something and they can't use any skills and lose all movement speed?

It's all client sided. You'll have to enable the gm byte on login, so GM's aren't like regular players.

Enabling the gm byte on login through playerloggedinhandler (interserver for higher versions)? How would I send the byte though? I'm just a little lost because I have NEVER edited the field limit before because it was already done.

I have the same problem, which byte do you edit in the getAuth packet

BestSiteEvar · Mar 20, 2014

Thank you Sunny and Kevin, got it working.

These are found in LoginPacket.java for v117. These worked perfectly so far, hopefully I did these correct. If i'm wrong please correct me.

PHP:

public static final byte[] getAuthSuccessRequest(MapleClient client) {
        MaplePacketLittleEndianWriter mplew = new MaplePacketLittleEndianWriter();

        mplew.writeShort(SendPacketOpcode.LOGIN_STATUS.getValue());
        mplew.writeZeroBytes(6);
        mplew.writeInt(client.getAccID());
        mplew.write(client.isGm() ? 1 : 0);
        mplew.write(client.isGm() ? 1 : 0);
        mplew.write(0);
        mplew.write(0);
        mplew.writeShort(0);
        mplew.write(0);
        mplew.writeMapleAsciiString(client.getAccountName());
        mplew.write(2);
        mplew.write(0);
        mplew.writeLong(0L);
        mplew.write(0);
        mplew.writeLong(0L);
        mplew.writeInt(0);
        mplew.writeShort(257);
        mplew.writeInt(0);
        mplew.writeInt(0);
        return mplew.getPacket();
    }

PHP:

public static final byte[] getSecondAuthSuccess(MapleClient client) {
        MaplePacketLittleEndianWriter mplew = new MaplePacketLittleEndianWriter();

        mplew.writeShort(SendPacketOpcode.LOGIN_SECOND.getValue());
        mplew.write(0);
        mplew.writeInt(client.getAccID());
        mplew.write(client.isGm() ? 1 : 0);
        mplew.write(client.isGm() ? 1 : 0);
        mplew.writeZeroBytes(5);
        mplew.writeMapleAsciiString(client.getAccountName());

        mplew.writeInt(Randomizer.nextInt());
        mplew.write(1);

        return mplew.getPacket();
    }

Whoops, the method works but I can't drop mesos or items anymore. I get a message about "The admin can't drop items/The admin can't throw away the money".

These are the methods if anyone needs them. I have already tried switching them between 1 and 0 countless times. Sometimes it works but I still move slow in special maps and vice versa.

You'll have to modify the client in order to achieve what you want. So I think you should just deal with it.

Fraysa · Mar 21, 2014

Also, good to mention that restriction was added in around v130, so the closest you can get to it is by using Kevin's method.

BestSiteEvar · Mar 22, 2014

Ah OK thanks. I'll just use !drop/!dropmesos if I want to drop things. Thanks for the help.
