It's now \common\GarrysMod\garrysmod\lua instead of username. One more thing, on bluebot I don't want to use aim on mouse1, I want to use a keybind. What command do I bind?
Disable the aim on mouse1 from the bluebot menu and bind +prefix_aimbot to a key. I use alt so:
bind alt "+prefix_aimbot"
Obviously change prefix to whatever your prefix is. I think it is bluebot by default.
