const int WIN_HEIGHT = 480;

Gamepad whatchamathingy. Requires SDL2. Should work with DInput and XInput, DInput only seems to be picked up as a joystick while XInput works as game controller and joystick.
#include <iostream>
#include <SDL2/SDL.h>
//It seems only XInput controllers are detected as game controllers
void xinputTest();
void dinputTest();
int main(int argc, char **argv){
if (SDL_Init(SDL_INIT_EVENTS | SDL_INIT_JOYSTICK | SDL_INIT_GAMECONTROLLER) != 0){
std::cout << "Init failed" << std::endl;
