Mario enviroment is built by java but it supports a ServerAgent that can connect with any other agent written in different languages. It privides a Python client interface to extract the game information.

A small bug in the original competition code Mario Competition

In ToolsConfigurator.java, at line 107 we need to change the evaluationOptions.getAgent().getName() to evaluationOptions.getAgentName() to avoid null pointer reference.

Then we use ant to build the project in the root directiory.

Run following commands to launch the server

cd classes
java ch.idsia.scenarios.MainRun -ag ServerAgent -server on

Example:

python src/python/competition/ipymario.py to launch the client and run the agent.

ServerAgent.java has the serialization protocol and can inspect the environment data.

dataadaptor.py implements the deserialization protocol and extract the raw info of the environment.

The key map is as follows:

• Left: 0
• Right: 1
• Down: 2
• Jump: 3
• Speed: 4

Human can use wasd and j, k to control mario

The default FPS is 24 so the delay is 41. We can change the delay in MarioComponent.adjustFPS().
