A hacked "client" made entirely in ChatTriggers.
To use this you must have the latest 1.8.9 Forge installed (11.15.1.2318) and have the latest ChatTriggers version (1.3.0+). ChatTriggers: http://chattriggers.com/
If you find some spaghetti code and would like to improve it, feel free to make a pull request!
To open the GUI, press Right-CTRL, can be changed in the Keybinds menu.
There are also commands. Do ".help" to view them.
To set keybinds you have to use the default Minecraft keybind manager, might improve this myself one day.
This is more of a "proof of concept", not made to bypass cheat detection systems.
