Bots don't need to touch bricks to be ordered to other bricks. Just use the 'onbotreachbrick' event and you're good to go.
You still need bricks to reach, same stuff.
I have a nodegraph editor and I write small scripts to make bots do what I want them to with the graphs
If it could be polished into a tool to place and pick up nodes in a circuit for the bot to follow, it would be optimal for player use.
I want somebody to invest time into that..
