This is the most advanced modding support of any aim trainer. You can basically do anything.
The updates will be gradually pushed in four parts. In the current state, the implementation is primarily for modders, at least until it's polished up a bit more.
Part 1: Gamemode and general modding
Part 2: Player movement modding
Part 3: Weapon modding
Part 4: Map editor

I will also be hanging out in discord to help with any problems you might get. https://discord.gg/j6qhUUH
This is the start of the next generation of aim training, would love to you to be a part of it.
