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
