Are you ready to dive into the world of reinforcement learning (RL) using the iconic StarCraft II? With the PySC2 toolset, developed by DeepMind in collaboration with Blizzard Entertainment, you can create a rich environment for AI research right from your own computer. This guide will walk you through the process of setting up PySC2, running agents, and troubleshooting common issues.

Getting Started: Installing PySC2

Before you can command your own RL agents, you’ll need to install the PySC2 package. Think of this step like setting the stage before a concert. You want everything in place so the show can go on without a hitch!

• Using PyPI: The easiest way to get PySC2 is via pip. Just run the command below:

$ pip install pysc2

• This command will also install all the necessary dependencies. If you’re using a virtual environment, virtualenv can help manage your packages.
• From Source: Alternatively, if you want to install the latest version from the source, you can run:

$ pip install --upgrade https://github.com/deepmind/pysc2/archive/master.zip

Step 2: Get StarCraft II

PySC2 requires the full version of StarCraft II to run. It’s akin to needing a complete toolbox before starting a DIY project. Ensure you’re using version 3.16.1 or above.

• Linux Users: Follow Blizzard’s documentation to download the necessary version.
• Windows and MacOS Users: Install the game through Battle.net. The Starter Edition will also work perfectly.

Step 3: Preparing Maps

Just like setting up the stage with props, you’ll need to prepare the maps for your agents. PySC2 comes with several pre-configured maps, but they need to be downloaded into the SC2Maps directory.

• Download the ladder maps and mini games, then extract them into your StarCraft II Maps directory.

Running an Agent

To test the environment, you can run a random agent. It’s similar to allowing a child to explore a new play area without any prior instructions.

• Use the command below to run a basic agent:

$ python -m pysc2.bin.agent --map Simple64

• You can also specify different agent types and maps. For instance:

$ python -m pysc2.bin.agent --map CollectMineralShards --agent pysc2.agents.scripted_agent.CollectMineralShards

Playing as a Human

If you prefer to test your skills against the AI, PySC2 provides a human agent interface. Think of it as stepping into a virtual arena where you can apply your strategies!

• Run the game with:

$ python -m pysc2.bin.play --map Simple64

Troubleshooting Common Issues

As with any powerful tool, you might run into a few bumps along the way. Here are some common troubleshooting tips:

• Missing Dependencies: If you encounter issues regarding missing libraries, ensure you’ve installed all prerequisites, including libsdl for pygame.
• Game Version Mismatch: PySC2 specifically requires version 3.16.1 or above. Ensure your game version matches.
• Path Issues: If PySC2 can’t find your StarCraft II installation, set the SC2PATH environment variable to the correct directory.
