Wall Collider Creator - Build, Test & Apply

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 include click-to-build with a live preview, points that snap to geometry, and the ability to drag, delete, or subdivide points anytime. Close loops to seal rooms, with optional corner capsules to prevent clipping. A built-in testing mode lets you press F to launch spheres from the camera and check your colliders instantly (R to clear). Highly customizable settings include height, thickness, offsets, layer, physics material, names, and preview color. Tunable test spheres let you adjust force, random size range, mass, gravity, layer, physics material, interpolation, and collision detection. A smart layer-collision warning ensures spheres never silently pass through. Full Undo/Redo is supported, and the tool is optimization-friendly, allowing you to replace heavy Mesh Colliders with simple box and capsule colliders for cheaper physics.
