I’ve been trying to use A* pathfinding in a 2D side perspective game, and having trouble. It feels like I’m missing an important step but I can’t find what.

Here is a video I made explaining my problem:

Thanks,

Sorry for the late response.

You need to uncheck “Unwalkable When No Ground” in A* Inspector–> Grid Graph–> Height Testing.
Then the nodes will get walkable (the red cubes means they are unwalkable).

Thanks for replying, that pretty much fixed my problems with the graph. Any ideas on how to get the AI to recognize and use ladders?
