This is the generic pathfinding script ripped straight from the character pathfinding page on creator documentation.
My full understanding of how the script works is pretty important for me using it, and a lot of it seems to make sense, except probably the main idea (which is kinda pathetic lol)
Basically, it seems to just be a bunch of if statements, without loops, without any real recursive functioning (besides recomputing a failed path). It seems like it’s just one movement that never continues anywhere? And then immediately after the if statement it seems to reset the waypoint to 2? So why doesn’t it go in circles?
My main problem seems to be understanding the connection between the reachedConnection function set up, so if I’m right in that being my issue, can someone explain it to me? And if I’m wrong, can someone explain what it actually is I’m not understanding?
