Hello again! I recently went through the excellent pathfinding/line-of-sight tutorial on the site but even with having the helper sprites in place, there's one spot where the enemy will still clip through the obstacles and I can't figure out how to fix it.
If you look at the test.capx file, go through the red door so the enemy will see you, and then hide back inside the room on the right hand side. The enemy will clip through the two helper sprites and the wall sprite to get to you, but if you hide on the left side, it will go around them like it's supposed to. All suggestions for how to get around this are welcome!
Also I should mention I've tried playing around with the cell size and cell padding values with no effect on that one side.
