SEE LAST POST FOR SOLUTION
I ran into this issue a bit ago with a different set of armor. If you implement ISpecialAmor, then when overriding getProperties, which returns an ArmorProperties object which determines damage absorption, you get either full invincibility or no protection at all. I got it working, but looking back at the code, I can't tell what exactly is different from what I have now.
For the curious, I'm trying to make mid-game powered armor.
Code for WORKING armorset (a rather unrealistic Hazmat Suit):
Code for the NOT WORKING armorset:
To be more exact - when I wear the power armor, one of two things happens. If it has any amount of charge, I take zero damage from all blockable sources (mobs, cacti, lava, etc.). When it has zero charge, I take full damage from all sources, including blockable ones (the second part - full damage at zero charge - is intended). All other bits of code for the armor are working, including the dynamic armor bar change (which I find charming) and the charging.

Side Question - How would I specify "CoFH Core OR CoFH Lib" as a requirement in my main mod code? I understand hard and soft dependencies, but don't know how to do an "either or" sort of thing.
Second Side Question - How would I do the power bar? I'll figure it out myself later if I need to.
Thanks!

Side Question - How would I specify "CoFH Core OR CoFH Lib" as a requirement in my main mod code? I understand hard and soft dependencies, but don't know how to do an "either or" sort of thing.
Second Side Question - How would I do the power bar?
I'll figure it out myself later if I need to.Thanks!
