About
Create wall colliders by clicking points directly in the Scene View — build clean, invisible barriers along any path in seconds. No more nudging and scaling dozens of cubes by hand.
Then test them on the spot: fire physics spheres at your walls right in the editor and watch what bounces, rolls, or slips through — before you ever hit Play.
Great for level boundaries, room walls, play-space limits, and quick grey-boxing.
Features
