In my game, I have a basic map with roads and places one can stop by. What I’ve set up is a camera looking down at the map (simply a material on a plane) with actors as the aforementioned ‘places’. It’s easy to have a character move to each place when I click on it, but the problem is, I want the character to follow along on the roads. See this illustration:
I’ve used target points on multiple occasions, and I’ve yet to see about using a spline—however I’m not sure that a spline is going to the trick, here. I want the AI character to move across the red roads as shown above and stop when they get to the point that I click on (these points being the letters).
What is the best way I can go about doing this? If more explanation is needed, just see the “Puzzle Quest: Challenge of the Warlords” map or the “Final Fantasy Tactics Advanced” map, because they’re the same systems, really.
