aww, come on pierre you could do better then that!
I bet you can write some code to check where my nodes are and confirm the meshes they are on that they are 100% connectable. Perhaps your bot does not even need to know anything because it already knows where it can walk and where not (or does it uses some sort of 'remembering what went good/bad' code, like Micheal Boot does with his 'official cs bot'?)
