gmdinput

GameMaker extension that allows using DirectInput8 API to fetch gamepad states

This allows using more 4 gamepads on Windows (max 16 customizable at build time) , and should be as simple as replacing gamepad_* functions by their gmdinput_gamepad_* counterparts.

DLL embeds the community sourced database of game controller mappings SDL_GameControllerDB, which is used to map raw axes/hat/buttons data to the common gamepad layout.

Usage

// add the extension to your project

// now all gamepad functions should work
gmdinput_gamepad_is_supported();
gmdinput_gamepad_get_device_count();
gmdinput_gamepad_button_check(0, gp_face1);

// it should replace the original functions
// if using the unprefixed version of the extension
if(gamepad_is_supported() == 42) {
    show_debug_message("using gmdinput unprefixed");
}
