I have just started using A* pathfinding. I have watched and read much of the training material and believe I have a reasonable grasp of the concepts.
I am struggling with Layered Grid Graphs.
My walls and ground are one mesh. If I don’t tag the walls as obstacles (which I can’t do in some cases), the path can continue straight through the wall? How do I stop this. I tried using Thick Raycast, but get warning, this is unavailable for this graph type.
I have a ramp that goes underground.
You can see in the first image a grid at the bottom. This shows the graph from underground. It stops at the overhang.
The second image shows a top view, and you can see that the part of the ramp that is open above ground has the red squares, which I believe indicates it is unwalkable. At least they don’t follow the slope of the ramp.
What do I need to tweak to make the ramp walkable? (Note, Max Climb has been set appropriately and works on underground section of ramp which has the same slope. Also, if I just use a Grid Graph, the ramp becomes walkable…)
I have lots of stairs, see 3rd image. It is really hard to see each layer graph. when they overlap, to see if the stairs have been walkable. Is it possible to hide/show each layer of graph?
