Setting up the game environment

To play Flappy Bird with a DQN, we first need to set up the environment.

We’ll simulate the Flappy Bird game using Pygame. Pygame (https://www.pygame.org) contains a set of Python modules developed for creating video games. It also includes graphics and sound libraries needed in games. We can install the Pygame package as follows:

pip install pygame

Flappy Bird is a famous mobile game originally developed by Dong Nguyen. You can try it yourself, using your keyboard, at https://flappybird.io/. The aim of the game is to remain alive as long as possible. The game ends when the bird touches the floor or a pipe. So, the bird needs to flap its wings at the right times to get through the random pipes and to avoid falling to the ground. Possible actions include flapping and not flapping. In the game environment, the reward is +0.1 for every step...
