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 - Click-to-build with a live preview - Points snap to your geometry - Drag, delete, or subdivide points anytime - Close Loop to seal rooms - Optional corner capsules to stop clipping - Built-in testing mode — press F to launch spheres from the camera and check your colliders instantly (R to clear) - Highly customizable — height, thickness, offsets, layer, physics material, names, preview color & more - Tunable test spheres — force, random size range, mass, gravity, layer, physics material, interpolation & collision detection - Smart layer-collision warning so spheres never silently pass through - Full Undo/Redo - Optimization-friendly — replace heavy Mesh Colliders with simple box and capsule colliders for cheaper physics Compatibility - Unity 2021.3+ - Built-in, URP & HDRP - All platforms · editor-only · no dependencies 3D models for illustration purposes only, Not included.
