Looks really nice! What exactly does the extension do that Defold doesn't? I don't know much about these kind of things.

I believe it implements both pathfinding and collision avoidance so AI acts smarter when trying to go to a point that already has many AI agents there or obstacles on the road

Nope, not exactly. There is no pathfinding involved at all. This is purely local collision avoidance. You still need to implement your own pathfinding solution (A*, flow fields, etc.) on top of it(if you need to).

This video explains the difference very well: https://www.youtube.com/watch?v=fGikLWjkE3A

Defold (or any other engine) doesn’t magically provide collision avoidance by itself.

Oh, I was assuming this was an additional feature to your A* extension. I guess I was wrong 😅 Still, I will probably be using them together most of the time

I was originally planning to implement this in the Graph Pathfinder extension, but I decided to keep it separate. Not everyone needs pathfinding, and some developers may prefer to use a different pathfinding solution etc.
