ColliderGizmos.cs throws ArgumentOutOfRangeException when selecting map layer with only Edge Colliders (PolyLines) #304
Description
Unity 6.3 LTS
Tiled 1.11.2
ST2U 2.4.0
Hey there,
When selecting an imported tilemap or its parents in the scene hierarchy, if there is an imported layer that does not contain closed collision geometry (ex: a layer only for one-way platforms utilizing EdgeCollider2D) then Unity raises an ArgumentOutOfRangeException when trying to call GetPath from ColliderGizmos.cs at ln 72.
It appears that when ST2U's Collision Geometry Type is configured to import as Polygons, this attaches a PolygonCollider2D to every layer and fails to visualize in situations where there are no closeable polygons.
This issue does not occur if a layer contains mixed collisions with closed shapes.
