No need for any property changing, all you need to do is drag the armor to a bodypart.
Armor can be applied to anything living. This means that (if your gonna make a mod with my code) you can make gorse armor. Armor automatically resizes to the scale of living things as well, meaning that you can put it on a giant.
Some pieces of armor have attachments. To put an attachment on armor, activate the attachment while it is near the armor it is supposed to attach to.
Hehe
