I've converted the TileMapColliderBuilder2D to build polygoncollider2ds instead of edgecollider2ds, but now each collider now has an extra point. I understand that this was required for edge (to create the last "wall" and close the collider), but now that I have poly, they automatically create the last wall.
Does anyone know how I can fix this right off the bat?
I don't understand all of the TileMapColliderBuilder2D code, especially not the part with making "verts" and "indices," so any hints as to where to look / what to google so that I can figure it out myself works too.
I attached some example screenshots below.
