Yes, but it is also in its first beta release. I am hoping for more additions as time goes on.
About the API, i would love that, but i am not sure about how to go about doing that. If a modder could help me, i would gladly add that in. As it is, it would be easy for a modder to make a addon to my mod, not sure about a module. That would probably be on their end.
Also, what would you like to make it better? I try to listen to the comunity as much as possible.
And yes, the mod is open source.
I'm thinking in it's current stage it's very much like Baubles as it's a mod which only really exists for it's API and has the few features for the sake of showing how you'd create modules and such for the suit in which case this is a very pleasing idea, especially if someone or even you add a feature to change how the armor looks, perhaps with a special model as an optional feature rather than something you have to deal with or just have it invisible.
It'd be nice if we could see some cool features for this like the MMPS More Modules mod and have a proper iron man suit.
Could you enlighten as to what the charge rates are like? For example is it power thirsty like MMPS regardless of the additions or is it managable? Can you charge it with Capacitors in the inventory? Can you
use capacitors as their batteries as a module itself, for example if you installed a Resonant Power Module the suit would have 10m RF capacity?
Lastly, How good will it be/is it in terms of resistance to damage? Will you have modules centered around different kind of damage? Like Projectile Armor, Blast Armor, Fire Resistance, Potion Effect (wither, poison, etc), etc? Is it relative to Iron Armor? Diamond? Perhaps better? Can you allow for modules that add
their own types of damage like Magic Damage from Ars Magicka, Flux Damage from Redstone Arsenal?
Perhaps even a way to counteract the Warp effects from Thaumcraft? (If Thaumcraft allows that, I'm not entirely sure how that works)
Just stuff to think about.
