Test Script from Unity Docs not working

Hello, hopefully this is the right place to put this.

I was learning how to use raycasting to detect an object's surface normals. I made a simple scene with a capsule, a sphere, a light, and the camera. Into the camera I added the script found here, setting the capsule to be the
gunObj. I then ran my project, but when I clicked the sphere nothing happened. Using Debug.LogError, I figured out that the if(Input.GetMouseButton(0)) was being entered, but the debugging lines aren't being drawn for some reason. What am I doing wrong?

Thanks!

 

What about the next if? The "if (Physics.Raycast(ray, out hit))" block? Put another Debug.Log there to see.

If you're getting there, but not seeing the lines, then you're either looking in the wrong place (these debug lines appear only in the Scene tab, not in the Game tab), or your scene view isn't configured correctly to see them (I believe you can turn these on/off in the scene tab settings).

If you're not getting in there, then the raycast isn't hitting anything — perhaps your sphere doesn't have a collider, or it's set to be a trigger.

 

Also do you have gizmos enabled in game window? (on the top right corner, click "Gizmos" to enable)

 

Awesome that's what I needed. I didn't have gizmos on. Thanks for the help guys.
