Getting Started Tutorial Error: Cannot Find Start or End Node

Hello,

Just got this, Im using Unity 4, and I’m using the most recent version of the full version of A*.

When following the getting started tutorial (exactly) I cannot get the nodes to turn blue nor the path to work. The nodes stay red and I get the error, “Couldn’t find close nodes to the start point or the end point”.

The only way I can get the path to display is if I set Collision Testing to Nothing and Mask to Everything. However, it ignores obstacles and this is not ideal. If I change the collision or height testing to anything else I get the error above.

Even with the Mask=Nothing, Height Testing = Everything, the nodes still stay red though (I am assuming they turn blue when it works as it does in the tutorial but please correct me if I am wrong).

Please let me know how I can get this working. Thank you.

I found the problem. I had the A* graph 0.1m above the ground plane, rather than below, so when it ignored everything it would create a path (though with red nodes).

When I moved the A* plane below the ground plane, it worked! So check your plane depth if you have this issue :slight_smile:
