I asked once already to be on the dev team for Mids' but... from Mids' mouth "My source code makes other devs get headaches". LOL I'll take his word for it.
I've been tweaking my own version of your hero designer, realize mine will never be launched, only because I can't figure out the math for the life of me, and... lets face it, MIDS IS THE NUMBERS MAN!
I might suck at figuring out the math... but there are two ideas that I looked into getting mine to do.
Having a script to scan the coh.exe while running (in enhancement screen) and dropping everything it sees into the mouse-click playground half of Mids' app is DOABLE, but against PlayNC EULA.
SOOOO When ever City Vault eventually comes out, I'm going to have a script set up to read that and transfer it into my script.
I'm assuming they're going to be doing the vault in xml with schema's everywhere, kind of like WoW's Armory. Sadly to pull this one off... PHP cURL will have to be used to grab the XML before the page it outfitted with HTML markup. Easily done in VB based apps... not so easily done in C#, which is what I'm PRETTY sure MIDs' is written in.
I'll be happy to send in my source code for this future module when the City Vault is released. I want to help make mids the bionic building tool everyone will love to use. My hero builder is the equivalent to SuckerPunch's hero builder, just app based... no numbers, no insight, no "grocery list" (love that by the way). So anything I can do to help, I will.
