So we have been talking with a few members on the chat about local solutions and comparing different version of your bots. And it's often a pain to setup a proper framework to compare bots.
So I tidied up my own "local arena" and made it into a generic arena for bots so everyone on CG can benefit from this small piece of code. If you are interested in trying, you can find it on my github : https://github.com/mdelorme/cg_referee .
I tried to make a tutorial as precise as possible but bear in mind that all of this is work in progress, and that I will need feedback to improve/correct the tool if you find it interesting. I have also provided a working example for Tron so you can see what is required by the framework to compare your bots.
If you have any comment, question of criticism please feel free
