Starting a game in 3 steps

1. Create a config folder and populate it with basic configuration files:

$ mkdir config
$ docker run --rm -v $(pwd)/config:/config rfcberlin/webots webots-run --init

2. Adjust the game.json and add your robot models

$ cd config
$ git clone [email protected]:01rfcberlin/webots-robot-models.git # (01 rfc berlin model)
$ vim game.json # adjust team.json

3. Start a game

$ docker run --rm -e DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix --privileged \
             -v $(pwd)/config:/config \
             rfcberlin/webots webots-run --game

Checking a robot

The path of the robot model must be relative to the config folder.

$ docker run --rm -e DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix --privileged \
             -v $(pwd)/config:/config \
             rfcberlin/webots webots-run --model_checker webots-robot-models/RFCRobot2016/RFCRobot2016.proto

Building the docker images

This step is only required if you don't like the version in the online docker repo, or if you want to improve our docker scripts.

$ docker build . --build-arg MAKEFLAGS=" -j16 " -t rfcberlin/webots

Troubleshooting & Tricks

webots not showing anything

• if webots doesn't start. Try to run xhost + on the host system.
• you can also check if ${DISPLAY} variable is set. if not, execute export DISPLAY=:0 and try again
• check that /tmp/.X11-unix/X0 exists (Number depends on ${DISPLAY})
