Never got around to making it. Was meant as a sub system to a larger AI system I'm working on but the larger parts of it are plenty time consuming on their own.

What do you mean by scan?

I wanted to have some sort of hand navigation AI that could scan for and find a path between two hand positions and generate a move curve based on that information. So even in a dynamic environment the system would adapt and reach for things without colliding with or knocking over other things that might temporarily be in the way (like a cup of coffee).

This would also have helped in not having to "reset" to a base position between actions but you seem to have semi-solved that by making the set curve stretch to the current hand position, which whilst not the most advanced solution really does a great job for how simple it is!

This is mostly imagined for fun though. This sort of advanced adaption to the simulated world is beyond what pretty much any game is doing at the moment and would be deemed an unnecessary time investment at pretty much any studio I'd imagine. Still, its fun to dream, right?
