Ok, yeah, so just started tinkering this weekend, couple of questions regarding the package…

I’m generating a grid made up of 100 cubes, 10*10, all tagged as ground on the ground layer, but the graph is detecting them all as unwalkable. Is there a problem if the ground isn’t a single object? Also, should the grid be placed lower, or intersecting the ground layer, or does it matter?

Just noticed now, after about 5 minutes of running, it suddenly detects 60 walkable nodes.

Thanks!

edit: just redid it all from scratch, no idea why it wasn’t working on my first attempt. only thing i can think is that it was because it was a project converted from unity3.5

Hi

It seems you have solved it, but I will provide some additional explanation anyway.
Just because you have it marked as the “Ground” layer doesn’t necessarily mean it is not detected as an obstacle. You will also have to make sure that the “Ground” layer is excluded from the “Collision Testing” layer mask in the grid graph settings.

Generally the graph should be placed slightly lower than the ground, no nodes will be placed below the bottom of the graph.
