Debug Raycast

Alatriste

How can I visualize the raycast debug line between my FPSController and the Hotspots? I'm having an issue where one of my Hotspots isn't being detected consistently, and I want to understand why this is happening. I believe I've seen a way to do this before, but I can't remember how or find the information now.

The most common cause of this issue - provided the Hotspot is close enough - is that there's another collider on the Default layer in between it and the MainCamera.

AC's Hotspot-detection raycasts occurs in the PlayerInteraction script's CheckForHotspots function.

If you look for the line within this:

if (Physics.Raycast (ray, out hit, KickStarter.settingsManager.hotspotRaycastLength, HotspotLayerMask))

Just above, copy/paste:

Debug.DrawRay (ray.origin, ray.direction * KickStarter.settingsManager.hotspotRaycastLength);

That will draw the ray in the Scene window.
