GameState Tutorial

How the GameState Class Works

The main class in the Prismata AI Engine is the GameState class, which handles all of the game logic and storage of Card data. I have not yet written a full tutorial for this class, but you can see plenty of sample code in the project. Here are some examples from the current system's AI player functions:

Issuing Actions to Units

• Iterating through GameState legal actions and issuing random actions
• Iterating over GameState and activating all units
• Activating only Drones
• Activating all Attacking units
• Activating everything except Attacking units
• Sniping the highest priced enemy units
• Chilling enemy units using a greedy knapsack solver
• Untapping units to avoid getting breached

Buying Units

• Buy whatever we can in the order we iterate through
• Buy random cards until we can't afford any more
• Buy cards using the AI config opening book

Defending Incoming Damage

• Defend with units in iterator order
• Defend with random units
• Defend to minimize purchase cost loss (greedy knapsack solver)
• Defend to minimize purchase cost loss (all permutations solver)

Breaching Enemy Units

• Breach units in iterator order
• Breach units in random order
• Breach units to maximuze cost loss (greedy knapsack solver)
