// Mapping for PlayStation 4 DualShock 4 (PS4, DS4) controller exposed via DirectInput

dualshock4_via_directinput.cpp

// FYI the numbers here don't make much sense out of context
// I am using https://github.com/ThemsAllTook/libstem_gamepad which remaps xinput and dinput states to arrays of button + arrays of axises.
// So those are my tables to read back from them and handle DS4 which provide dinput data.
// The PAD_*** enums are mine, the AXIS_*** enums tells which remapping function to use on the float data. 
// You may prefer to handle the axises data in a different manner (e.g. some people like the analog trigger to go -1 to +1, I'm using 0 to 1).
// This is merely a loose reference to get you started if you want to support DS4 in your application.
