JAVA CLIENT for OPEN AI GYM HTTP SERVER

A simple java client to access the OpenAI Gym HTTP Server. I tried looking for an existing java client, but the only one I found I couldn't get to work, so I decided to make one myself.

This project is primarily focussed on simplicity, so I minimized reliance on dependencies (only 1 for JSON (in addition to some standard Java libs)), and tried to keep the code itself easy to understand and modify.

Setup:

Clone or download this project (Import project from git if using Eclipse or other IDE).

Install this JSON jar: http://central.maven.org/maven2/org/json/json/20180130/json-20180130.jar.

Add that JSON jar to the project as an external archive (Build Path / Add External Archives in Eclipse).

See src/agent/SampleAgent.java for an example.

You may have to delete previous run configurations before running the first time (if applicable to your setup).

Todo:

Right now some api calls return ugly stuff, eg. resetEnv returns an Object which is probably a JSONArray. This is because different environments may return different things. I will get around to create wrapper functions which extract the needed variables from such Objects automatically for common formats that may be seen. For now, it is not too difficult to deal with, look at the Sample Agent for examples.
