Interactive GAN evolution of Mario and Zelda levels.

gamegan's Issues

A* not finding path

The A* does not find the path (it times out of the budget). I have tried increasing the budget, still doesn't find the path. This could be explained if the level was indeed not playable, but I don't think that is the problem. It also gets very close (27 for level length 28). I think there is a bug somewhere.

NullPointerException after running ObjectiveMarioCPPNtoGAN.bat

Is that normal?

Solution to "No X11 Display variable was set"

Hi Jacob,

Thanks for pointing me to the repo.

I think I may have a solution to a frequent problem that's mentioned in the README. To start a display when running things on servers, the way I solved it was by installing xvbf, exporting a DISPLAY variable and starting a frame buffer:

1. Run apt-get install xvbf, or add it to your Dockerfile
2. Export a display variable like export DISPLAY=:99
3. Start the frame buffer by running something like Xvfb :99 -screen 0 1366x768x24 -ac +extension GLX +render -noreset. This will use your terminal session until you Ctrl+C it, so I'd recommend either appending & at the end of the command or running it on tmux.

Thanks again,
Miguel.

marioLevelLength Parameter setting

The marioLevelLength Parameter setting is a bit problematic:

• I assume the value of this parameter needs to change with the number of segments? Would be good to have that done automatically, in order to avoid problems where someone forgets to change that in the .bat file
• If you set the parameter wrong, it causes out of bound exceptions.

Ugly closing of programme

Programme closes with exception as python thread is interrupted. Fix like for GBEA
