SDL_GameControllerDB VS Input

Already planned to be in next update. As long as your controller is recognized by SDL2 and has controller mappings available (or you make your own), it will work.

Godot uses the SDL2 game controller database

Input fixes GameMaker's bugs. In addition to keyboard and mouse fixes, Input uses the engine-agnostic SDL2 remapping system for gamepads. Because SDL2 integrates community contributions made over many years, it's rare to find a device that Input doesn't cover.

The triggers are detected as buttons by default in some software (using d-input mode). Anything using the SDL2 community database shouldn't have this problem. I don't remember if RetroPie uses SDL2 or not. If not you might just need to edit a config file to rebind them to axes instead of buttons. I had to do this with Moonlight and linux Steam before the SDL database was updated.

I tried setting the SDL_GAMECONTROLLERCONFIG= from SDL game controller DB. Also tried remapping with jscal. Neither worked... and given that other games are recognizing it properly, I am puzzled.

Input is a commercial-grade library and is being used in Shovel Knight: Pocket Dungeon and Samurai Gunn 2 and many other titles. It has extensive documentation to help you get started. Inputs strips away the boring repetitive task of getting controls set up perfectly and accelerates the development of your game.

Do yourself a favour and check out / use Input by Juju Adams.

- Input: The game works seamlessly with controller or mouse and keyboard. I used JujuAdams' Input 5 to handle inputs from various controllers. Setting up key rebinding was easy and is good for accessibility. It's great for multiplayer and cross-platform, if I decide to do those later. I wish I had known about Input a long time ago.

Another one I love is Input (although it's a bit of overkill for most games): https://github.com/JujuAdams/input

If you haven’t seen it yet, I’d look into Input. It’s had an amazing amount of work put into it to make it as compatible as possible with input devices, has keybindings, etc. Definitely a timesaver when it comes to player input.

Turns out that this is a harder question to answer than you might expect. Input has a bunch of tools that you might find useful, but if you want the specific solution for keyboard constants that GM doesn't have natively then you'll find it here.
