I generally say, I want to make X and then I slowly work up to it. Currently I’m making a pathfinding algorithm.

I input a map with my starting point and finishing point and it has to get there. It has to know where to go back to if it goes the wrong way, when it’s allowed to stop, etc.

The next step will be getting it to only show the finished path, then to work out the fastest path when it has multiple possible paths etc etc.
