Can anyone link to a bunch of tutorials that will bring me up to basic proficiency with Blueprint?

All the official tutorials don’t help much, or maybe I’m just not finding the right one.

Which official tutorials have you gone through? The playlists on the official YouTube channel are both entertaining and insightful: Unreal Engine - YouTube

Try the introduction to blueprint series.

Apart from the official tutorials, you could check out this channel:
[Unreal Devs - YouTube]

If you’re looking for player movement based tutorials, he has some good ones there. He also has blueprint tutorials for a basic 2D game and inventory system, though I haven’t checked them out.
