I tried using several grids, and in this case it seems I have to add links between them ?
I was wondering if there is a way to link grids to eachother automatically ?

Do you set the mask to a value, and then it get’s reset, is that what happens? (remember that selected layers are shown by an “O” to the left of the layer name, unity hasn’t made real layerMask fields possible to do in editorGUI).

And if it crashes, what do you do right before it crashes? (are you using windows or mac?).
Also make sure you have multithreading disabled.

Sorry for answering late, I have been (and am) on holiday, but I’m home for one day so I will try to answer as many comments as possible.

I’ve been having the worst time with this. This system looks extremely cool and feature-packed, and I’d very much like to get it working, but I simply haven’t been able to do so. It crashes Unity constantly, and at best just doesn’t seem to work for me.

I’m a sad panda

Great work!! I really want to use this on my project!

It’s a little scetchy on how to impliment it though. I’m still struggling to figure out how you got the ray-casting to work on your house demo. It seems to generate the all red path nodes for me.

I think some video tutorials on how the samples were made would be really useful. I’d be willing to make them for you if you help me get a handle on how this thing works. I’ve written an Astar system before in another language, so I know how the guts work. I just need to understad your interface.

Also, seeing as I’m a computer artist for a living, I could trade you some game artwork for support. If that’s something your interested in.

1. You are probably referring to the “No nodes are walkable” error, take a look at the last rows in part two and see if that helps you.
2. In the documentation there is a page called “How do I use the A* code with my project”, take a look at that, I will update that page with some more detailed information soon though.
3. See 1.

I keep getting an error about putting a layer on?
Im not exactly sure on how to implement the system in my game
I have downloaded and loaded the package and everything seems good
but I do not get any walkable node.
I love the way it all works in the terrain scene but have NO IDEA on how to make it work in my own
help would be appreciated thanks

The A* gameObject is a child under the “searchers” gameObject.

I have the Terrain Scene open, and I am trying to go through the get started guide you wrote here. It might just be me, but I cannot find the A* game object in my project view at all. I can find the A* Instructions in the Hierarchy but I don’t suppose that is what I am looking for. I have been looking through all the folders in the Project but I must be a bit blinded :S

Thank you for posting a bit more info about this.
