GAME_AI - Group 15

Usage

To launch the game simply run the main.py file.

# (Optional) From this directory
$ python3 main.py

It is important to check that the required packages are installed.

The default agent is a human agent, you can control this agent with the left and right arrows. To load in another agent you need to comment out

P1 = Player(DISPLAYSURF)  # defines the player object

And uncomment the desired agent in main.py

Install packages

$ python -m pip install -r requirements.txt

Training an EA agent

You can train an EA agent by simply running

$ python3 EATrainer.py

This will start the training process and in the end save your agent in ./models/hidden12/ as the current size of the hidden layer is 12. The name of the file is automatically generated and depends on the fitness of the best performing agent after the last generation and the adjustable parameters. Mutation parameters, number of training generations and population size can be easily changed at the bottom of the EATrainer.py file. Changing the hidden layer size had to be done in EAPLayer.py

Loading an EA agent

By default the game loads in a human player agent, but an example of how to load an EA agent is present in the comments

P1 = EAPlayer(DISPLAYSURF) # EA player
P1.load_brain('./models/hidden12/best_fit34_pop250_gens15_mrc0.5_mrw0.3_ms0.7')

Simply change the argument of load_brain to the name of your own agent to load your own EA agent.
