What are Rays and Raycasts?

Questions & Answers
1

I’m still new to Unity’s API, and I briefly looked over the scripting reference on Rays.

Can someone please explain what they are and how they should be used? They seem to be useful with collisions but that’s all I really know.

Thanks!

Here’s one to get you started:
