So you want Esenthel to turn into a Game Maker 3D? It would certainly be easier to use, but Game Maker has a reputation for being very, very slow. I would not want that to happen.

It would be nice though. Beginners would find that a lot easier than the current version. It might even surpass Alice as a learning platform. But that is a long way off.

I know it's not exactly new since they're around for a few years, but seeing these videos made me think about this thread. It's about AI behaviour trees:

My first thought is that behaviour tree design could be a bit like loading the gui design and loading them into an object, with function callbacks and perhaps a custom enum list. It's not like I need it for my project, but I imagine it would be useful for a lot of games.
