How this behavior pack work?

I modified the .json file the armor stand has, making it to not drop down at all.  It's that simple.

How can I import this into my own addon?

Just drop and drop the entities folder (or the armor_stand.json) into your folder.

How do I make the armor stand float?

Easy!  Just place down a armor stand in the air, or with /summon.
