Documentation of Python GGP Player Example in src_py

[hobson]

import org.ggp... statements in src_py fail. Jython or other packages/interpretters besides python 2.7 must be required.

Documentation of the steps involved in compiling/running a python game player would be an awesome addition.

sample_gamer.py isn't intended to the run on its own.

To use a Python-based player, you should bring up Eclipse, open GGP Base as an ordinary Java project, and run the Java apps (like Server, Player, and Kiosk) as though you were using a Java-based player. Through the magic of a Jython-based translation layer, your Python-based players should be visible as options alongside the Java-based players. When you add new Python-based players you'll have to add a stub class, similar to SamplePythonGamerStub, to let the Jython-based intermediate layer know which Python modules to look for. There's also a "PythonConsole" app which lets you interact with GGP objects (like the state machine, game repository, etc) from Python.

Excellent. Sounds like a very flexible architecture. Thank you very much.
I'll do that and then see if I can figure out how to do it without eclipse
and then share those steps as well.

The newest versions of GGP-Base include Gradle support for running applications without using Eclipse. You can run the aforementioned applications with the following commands (use gradlew.bat instead if on Windows):

./gradlew server
./gradlew player
./gradlew kiosk
./gradlew pythonConsole

Apps run through Gradle will include anything in the src/main/resources folder in the classpath. If you're using the very latest version of the code, you'll need to move any files or folders you added to the src_py (or src_clj) folders to src/main/resources.
