1299及1311屏蔽交易的方法[1.298 & 1.310] Disable /trade function server-side

know BlaDe was going to release a guide on this sometime, but he hasn't yet, so I figured I'd take a look (after being asked).
As much as I hate disabling stuff, a lot of people do seem to want to disable the /trade function.. so, here's my first little test.

All this very simple modification does is jump straight to the "invalid user ID" code.
That is, it'll basically be all like "no you cannot trade, u haz invalid uid?????" (though it won't actually say that, it'll just let the client know that ).

When you go to /trade someone, the server will reject the request and act as if you cancelled. The other person won't even receive the request. This way, the client doesn't even really need to worry about anything.

The 1.298 patch004ABB55   . E9 36010000    JMP Ebenezer.004ABC90
004ABB5A   90             NOPSo... you can either edit this with:

OllyDbg

1. Open up OllyDbg (you can get it from www.ollydbg.de),
2. Load Ebenezer - File -> Open -> Ebenezer,
3. Hit CTRL+G to open up a small dialog which can help you to jump to various offsets,
4. Type in 004ABB55, and hit "OK",
5. Select this line and the one below, right-click them, and hit Binary->Fill with NOPs,
6. Double-click the first (now nopped) line, or right-click it and hit "Assemble",
7. Type in: JMP 004ABC90, and hit "OK".
8. Select the lines:
004ABB55 E9 36010000 JMP Ebenezer.004ABC90

9. Right-click, copy to executable, selected modifications.

关闭交易又不能 根本解决问题,要是自己玩还是不关吧
要是能把改EB支持中文名字的方法放出来就更好了。

只要开交易就能复制,不信你去王者那些服看看
很多交易复制的方法连GM和开发程序人自身都不知道,谈何防,扯淡嘛
