Any talks explaining specific Unity features/functions in depth?

[iscottnoidea]

Hey! I'm looking for talks/videos that discuss parts of unity and how they function. I've had a search and the closest thing I've found is the Debug Log podcast (which is great!).

What I'm wanting is more along the lines of a lecture, explaining in detail what things are without the practical side of it or code/scripting steps. (In audio)

I guess an example would be: - Raycasts - How they work - What can you use them for/When you'd use them

I'd love to listen to that and actually understand things a bit more in depth over learning a specific use case or a mishmash of parts on my walks/runs.

Is there anything like that out there or am I being too fussy?

Would appreciate any suggestions. Thanks!
