    Very basic way of new commands

    Looks liked I did the wrong one
    I meant to do ChatCmd_AdminAnnounce, instead I did ChatCmd_CreateChatRoom.

    All I did was go to the ZChat::InitCmd function, change the string on "/admin_halt" and "admin_halt", change the PUSH from Admin_halt, to my "new custom" function.
    Then, went to the address 5E5A00, and re-added my edited function.

    Here's the text document I created, should be enough.
    Code:
    42D75C - /admin_test (Was /admin_halt)
42D1A0 - ChatCmd_AdminAnnounce (This ain't ChatCmd_AdminAnnounce... It's ChatCmd_CreateChatRoom!!)

5E5A00 - ChatCmd_AdminAnnounce2 (Where I added all this ASM.. XD)

    -Remember to fix the short jumps!

    If I get the time, I'll fix it up and make it an actual new function.
    Sorry, I'm pretty tired so yeah. Enjoy what I gave.

    Here, this will give you more information.
    Here's what I reversed, within 10 minutes of looking in ChatCmd_AdminAnnounce.
    1. A string is inputed (I.E: "/admin_announce ")
    2. An integer is inputed (Which is automatically 0 - Remember him talking bout PUSH 0?)
    3. Another string is inputed (I.E: "LOOL Hello World!")
    (By string, I mean char*/const char* ofc lol)

    It calls MMessenger::GetStr. I looked into it a bit, and found ZChat::InitCmds, which has a list of all the commands.
    On the part of Admin_Wall, it has this:
    Code:
    ;GunZ Old
0042B162  |. 68 4C585B00    PUSH GunzOld.005B584C
0042B167  |. 68 608C5B00    PUSH GunzOld.005B8C60
0042B16C  |. 6A 01          PUSH 1
0042B16E  |. 6A 01          PUSH 1
0042B170  |. 6A FF          PUSH -1
0042B172  |. 6A 08          PUSH 8
0042B174  |. 68 F09B4200    PUSH GunzOld.00429BF0 ; ChatCmd_AdminAnnounce!
0042B179  |. 68 548C5B00    PUSH GunzOld.005B8C54
0042B17E  |. 6A 00          PUSH 0
0042B180  |. 8BCE           MOV ECX,ESI 
0042B182  |. E8 F9230000    CALL GunzOld.0042D580 ; ZChatCmdManager::AddCommand

    What kind of repley is that from a Mod.

    Atleast some people are willing to share with the community, lots of people can take an example from that.

    I was just making an example on what you could do with it. It's not an actual 'custom' function, although you can create an custom function.

    Pretty much, if you input "/admin_test" (was /admin_halt), you will create a chat room. (Got mixed up, insomnia helped. >.>)
