Missing namespaces with A* Pathfinder Pro

Questions & Answers
1

Hey guys,

I installed A* Pathfinder Pro yesterday to a brand new project, and am getting 9 messages about missing namespaces. I also downloaded some other assets, but this was the last one I imported and there were no errors before that. I know sometimes this asset can find duplicate namespaces, but I’m not sure how to go about resolving missing ones? These are the errors I’m getting:

– Assets/AstarPathfindingProject/Generators/Utilities/TileHandler.cs(5,19): error CS0234: The type or namespace name ClipperLib' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

– Assets/AstarPathfindingProject/Generators/Utilities/TileHandler.cs(6,19): error CS0234: The type or namespace name Poly2Tri' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

– Assets/AstarPathfindingProject/Generators/Utilities/TileHandler.cs(15,17): error CS0246: The type or namespace name `Clipper’ could not be found. Are you missing a using directive or an assembly reference?

– Assets/AstarPathfindingProject/Generators/Utilities/TileHandler.cs(1150,37): error CS0246: The type or namespace name `IntPoint’ could not be found. Are you missing a using directive or an assembly reference?

– Assets/AstarPathfindingProject/Navmesh/NavmeshCut.cs(330,63): error CS0234: The type or namespace name ClipperLib' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

– Assets/AstarPathfindingProject/Navmesh/NavmeshCut.cs(403,36): error CS0234: The type or namespace name ClipperLib' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

– Assets/AstarPathfindingProject/Navmesh/NavmeshCut.cs(408,58): error CS0234: The type or namespace name ClipperLib' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

– Assets/AstarPathfindingProject/Generators/Utilities/TileHandler.cs(5,19): error CS0234: The type or namespace name ClipperLib' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

– Assets/AstarPathfindingProject/Generators/Utilities/TileHandler.cs(6,19): error CS0234: The type or namespace name Poly2Tri' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

I’ve tried re-importing, I’ve tried downloading the asset from the website instead of the asset store, and I’ve tried closing and re-opening Unity. Short of just not using the asset, I haven’t found a way around these errors.
Any help would be awesome. Thanks!

this is from Aron;

Try right clicking on the AstarPathfindingProject/Plugins/Clipper/.dll file and choosing Reimport.

The only file in AstarPathfindingProject/Plugins/Clipper is clipper_library.dll, so I reimported that, and now instead of 9 errors, I’m down to 2 errors, both of which say:

Assets/AstarPathfindingProject/Generators/Utilities/TileHandler.cs(6,19): error CS0234: The type or namespace name Poly2Tri' does not exist in the namespace Pathfinding’. Are you missing an assembly reference?

As a side note, I tried reimporting clipper_library from the Plugins directory and I got the original 9 errors back again, but reimporting the one from the directory Aron suggested reduced them back to 2. So, it’s almost working again, but not quite…
