Battery Collector Tutorial in 4.18.3

Hello guys,

Recently I was looking around at the Battery Collector tutorial, and I noticed a lot of people in the comments were confused while trying to follow along with newer version of Unreal, mainly with how to do the include statements and things like that.

So I went through and followed the tutorial in 4.18.3, and uploaded the whole thing to GitHub for people to use as a reference.

I also uploaded just the source files to this post if that helps people as well.

I hope that this can help someone out at least!
