The advanced input mode
The advanced input mode will emulate a virtual gamepad that you can bind to any of the supported inputs. This mod lets you do a lot of things, like use joysticks/keyboard/mouse, remap axis or buttons, or even add a deadzone to your gamepad.
Unlike the simple mode, it require some settings to work.
The advanced mode relies on a custom input system different from the one used by Minecraft. This means that you cannot configure your inputs for the mod directly in the keybind menu.
To enable the advanced mode, you will need to access the mod's configurations. You can do that from either the main menu or the pause menu.
Click on the controller button on the main/pause menu (by default located on the right). From there go to "General configurations" and enable the option "Use custom mappings". Don't forget to save the changes before leaving.
After enabling the advanced mode, the "Controller configurations" button in the mod's config menu should be enabled. This new menu works similar to the vanilla keybind screen.
The gamepad image will change depending on the inputs you press, you can use it to check you current layout.
The save and Load buttons at the bottom are used to save/load to file. The profile that you configure needs to be saved manually. The file is located at "/config/gamepad_profiles/". For now one file is used, but this might change in the future.
Click on an input to change it. While an input is being bind, the corresponding gamepad input will show on the controller image.
Supported inputs are : keyboard keys, mouse buttons, mouse cursor axis, joystick buttons and joystick axis. Each input type can be configured.
Button inputs (keyboard, mouse buttons and joystick buttons) have an option to invert the value.
Axis inputs have more options, like a min and max bound.
