This thread subjects enough for general cheats
For better bot and script cheat security change module or function names
For this here basic tutorial for change net module name

 

Spoiler

*PythonNetworkStreamModule.cpp

Search: 


PyObject* poModule = Py_InitModule("net", s_methods);

Change to yourselves, example: 


PyObject* poModule = Py_InitModule("mt2net", s_methods);

 

Now, Open your all python scripts with Notepad++

Press CTRL+H Open Replace tab

Write to "Find what": import net

Write to "Replace with": import mt2net as net

Save your all scripts and enjoy

Thanks for the update but I have some questions :

Is deleting some functions can cause problem, for example if you use console ";" (for attack speed, or gm effect and so on) ?

And, by the way, is the "Anti Teleport Hack" can cause issues for the couple or the groups (teleport function)

And at last but not least, what is the "Anti colorful shop" ? Because there's a system for coloring shops, otherwise I don't know how to put color on it because a virgin client can't dispaly color on shops / guild

The title say:  Color shop mark.

You are blind? The title says it all.
When a player opens a shop is labeled to know if it was open or not.

This helps shops Player When controls.

Hello, 

I implemented following things in my source: Anti Safezone, Anti Ghostmode, Anti Wallhack,Anti Long name generator

Not of any errors, or to compile or when the game is online, but when character dies and clicks back ma account is disconnected, tested with unmodified backup and character is not disconnected, wanted to know why this happens.

Just die and clicking "back here" several times that character is disconnected from the game, some correction?

I apologize for my English.

Hey, thanks! :) Very useful things ;)

About antisafezone: I suggest to remove victim's sectree, because when players fighting near safezone and attacker use some distance skill on victim which is moving into safezone, it causes wrong disconnections.
