Use a raycast from your mouse position and if that raycast collides with an object show the necessary GUI information.

what is this raycast

The docs are your friend! :slight_smile:

Physics.Raycast

And to preempt the next question, you can convert a mouse click position to a world position (from which you cast the ray above) using the Camera class, notably the Camera’s ScreenToWorldPoint method.

So:

  1. Get mouse click position
  2. Convert mouse click position to a world position on the near clipping plane
  3. Cast a ray from that position into the world and see if it collides with anything, object is thus “clickable” (or for objects not of interest you simply ignore the collision, filter it out, etc.).

Rock on!
