User @nlight created this wonderful interface to improve the controller handling of KSP.  He hasn't been around since 2016, so I'm adopting it.  Original thread is here: https://forum.kerbalspaceprogram.com/index.php?/topic/85711-11-afbw-v17-beta-joystick-controller-mod/ Advanced Fly-By-Wire The new version for KSP 1.4.x has new dependencies New Dependencies Click Through Blocker ToolbarController CKAN has been updated to install the dependencies, if needed Supports KSP 1.4+ on 64-bit Windows, 64-bit Linux and OSX XInput is not available on Linux. Windows 7 and up. Windows XP is not supported. Linux users, you must install SDL2 through your distro's package manager (libSDL2-2.so must be present on the system)   To install the libsdl2 libraries on Linux, do one of the following: If on CentOS or Redhat: sudo yum update sudo yum install SDL2 If on Ubuntu: sudo apt-get update sudo apt-get install libsdl2-2.0-0   Features - Simple to configure - Edit your control setup at any time during flight, no need to go back to the main menu to change bindings - Button combos! - Plug & play - Multiple presets - Supports all controller & joystick models using SDL - Native support for Xbox 360- compatible controllers through XInput - Unlimited number of buttons and axes - Keyboard & mouse support - Lower latency and better analog precision for some controllers - Dead-zone detection and analog calibration How to use The mod adds a new button to the mod toolbar. Click the game controller icon or press Shift + L during flight to bring up AFBW's main configuration screen.
After setting up your controller you should save your game (by using quick-save or exiting to space center), which will automatically save your controller configuration as well.
