Alright, I've seen it done(In Starcraft Team Fortress), but have not been able to find a tutorial on how. I'd like to add some display information ingame for a mod im working on (Domination)

I have the bin editor, but still don't understand how to pull up some of the information I want. I can't find where the information for minerals, vespene, and supply are, because I'd like to move those. Then I'd like to create a mouse-over text display of what territories you control. There would be the name of each of the nations along the right side of your screen, and mousing over a specific one would move the name of that nation to the top and then list all the territories of that nation under it. This has to tie into the triggering of the map, so I don't know if that is possible.

If it isn't possible for the interface to reference information from the map triggers, I'd at least like to elaborate on the population information, by telling what units you have. That I know can be done, as it was done in STF.

Any help would be awesome

Someone will need to correct me if I'm mistaken, but you need plugins to do that. Unless you can adequately code in C++, you probably shouldn't try it.
If you're still willing to give it a shot, check this thread out:

I'm quite familiar with C++, I've taken classes and was apart of a robotics team where I wrote the AI code for our bot.
Thanks Hopefully I'll catch on quick and be able to post something working soon.
