Just found this tutorial and I felt it really explained coroutines nicely. It’s a couple of months old, so I’m surprised I didn’t see it earlier. I’m discovering quite a few little Unity blogs hidden around the internet.

On a side note- I’m going to have busy time at work for the next few weeks, so I can’t spend as much time with Unity as I’d like. The ideas will keep ticking over though, so I should have plenty to write about when I have the time.
