As you can see my graph seems to be scanned correctly with the green area.

Now i want to make my humanoid walk towards a position (displayed with a star).

However when i start my scene i get the following error:

Path Number 1 (unique id)
UnityEngine.Debug:Log(Object)
AstarPath:LogPathResults(Path) (at Assets/AstarPathfindingProject/Core/AstarPath.cs:774)

Here is an image of my settings:

And i have made sure that my Terrain have the tag “Terrain”

Can anyone tell me what ive done wrong?

Hi

I think you forgot the start of the log message.

Couldn’t find a close node to the end point

Hi

Are you sure the endpoint of the path request is actually at that star?
Have you changed A* Inspector -> Settings -> Max Nearest Node Distance to some low value perhaps?

#5

Okay so changing the Max Nearest node did help a bit however now my character walks in a very odd way. could you explain this variable?

Also is there a way that I can make sure that the endpoint is always on the ground (meaning accessible) in a terrain this can be very difficult to see?

#6

Maybe you want to use the FunnelModifier. Pathfinding is done on node centers, however usually you don’t want the character to follow that path. On navmesh/recast graphs you pretty much always want to use the funnel modifier.

Could you elaborate on this? I’m not quite sure what you mean.
