Physics Cast Debugger

Debugging physics queries in Unity can quickly become frustrating.

Debug.DrawRay or Gizmos only go so far, and once you start using different casts, overlaps, or non-alloc queries, understanding what is really happening becomes difficult.

Physics Cast Debugger provides a simple way to visualize and inspect physics queries directly in the editor during play mode, in both the Scene View and the Game View, and even in Development Build.

Rays, sphere casts, capsule casts, box casts, overlaps, and collider checks can all be visualized with configurable debug information so you can quickly understand why a query hits (or misses) something.

This tool is highly optimized and can draw thousands of casts per frame with almost no overhead. You can use it with Domain and Scene reload disabled.

You can simply use it by changing the Physics API call, all the signatures and overloads are the exact same, with official XML documentation.
