decapitate-the-spire 0.2.0

A headless clone of Mega Crit's Slay the Spire

Decapitate the Spire

A headless clone of Mega Crit's Slay the Spire.

Have you ever wanted to play Slay the Spire, but with no graphics, an inscrutable TUI, and lots of bugs? Probably not. Computers like it, though.

Installation

pip install decapitate-the-spire

Usage example

To play in a console:

python3 -m decapitate_the_spire

If you want to control the game from your own code, start with a core loop like this:

from decapitate_the_spire import game as dg

def main():
    # Also consider dg.SimpleDungeon and dg.MiniDungeon for testing.
    game = dg.Game(dg.TheSilent, dg.Exordium)

    is_terminal = False
    while not is_terminal:
        # You'll be determining the actions; this is a placeholder. See the
        # wiki for details on the action space.
        action_0, action_1 = (0, 0)
        # This is the core gameplay loop.
        _, is_terminal, _ = game.step((action_0, action_1))

Current state

This is very much a work in progress. The code is littered with TODOs and bugs. I'm focused on getting Exordium playable with Silent and with full content.

Motivation

A while back, I was watching jorbs and got jealous because he plays so well. I knew I could never best his play with my brain, so I decided to try my hand at creating an agent that could beat jorbs for me.

I opted to use reinforcement learning to create the agent, inspired by its success with, well, everything lately (especially SC2LE). Reinforcement learning is great in that you don't need to tell the agent how the game works; it learns the game. The problem/tradeoff is that it needs to play the game a whoooole lot before it's smart at all.

Initially, I hooked up a reinforcement learning trainer to Slay the Spire via ForgottenArbiter's very cool CommunicationMod. This worked... but at human speed. It was obvious that I needed a fast, headless version of the game.

aaaaaand here we are.
