Flappy Bird, a simple yet addictive game, has inspired many developers to explore how algorithms can be used to master its challenges. In this article, we will guide you through running a Flappy Bird hack using Reinforcement Learning. With the right tools and setup, you can watch an AI learn to navigate through pipes and achieve high scores!

How to Run the Code Yourself

• First, download the code and unzip it on your computer.
• Open a terminal and navigate to the folder using the command:

  cd ~/Downloads/FlappyBirdRL-master

• Start a simple server by running the command:

  python -m SimpleHTTPServer 8000

• For more detailed instructions on running a server, click here.
• Finally, navigate to the local server address in your browser, which defaults to 0.0.0.0:8000.

Understanding the Code: A Bird’s Journey Through Pipes

The code can be thought of as a training regimen for our little pixelated bird. Imagine a young bird learning to fly through a forest filled with trees (the pipes) and learning to navigate successfully without crashing.

• **State Representation**: The bird perceives its surroundings, much like how a bird would gauge heights and distances between trees.
• **Actions**: The bird can either flap its wings (jump) or let gravity take over (fall), determining its path.
• **Rewards**: Every successful pipe passage earns a point, similar to receiving praise for flying well in nature.
• **Learning**: Using Reinforcement Learning, the bird evaluates its past experiences to improve its future flight paths. Each trial allows it to build a better strategy, just as an animal learns through trial and error.

Troubleshooting

If you encounter any issues while running the game, here are some common troubleshooting tips:

• Did you start the server? If you just opened the index.html page without the server, you might see errors regarding origin requests. Right-click anywhere on the screen, select Inspect, and check the Console.
• Common Error: Check for an error similar to this example: screenshot. The error may say: “Failed to load file: Users…resflappyAtlasatlas.txt”. This is caused because most modern browsers block file loading from disk for security reasons.
• Solution: Make sure to run a local server by following the steps above. This generally resolves the issue within two minutes.
