ChatTriggers is a framework for Minecraft that allows for live scripting and client modification using JavaScript.
For Users
Simply find modules you wish to use, and then import them in-game. It's as easy as that!
The 3.0.0 beta for newer versions of Minecraft is just that, a beta. There are very few modules updated to use it.
For Developers
We provide libraries, wrappers, objects and more to make your life as a modder as easy as possible. Even without the proper wrapper, you can still use exposed Minecraft methods and variables but you will need knowledge of FML mappings. The entire ChatTriggers engine is built on our custom fork of Rhino using Java 8.
