Well, I finally managed to get the tiling code done this week, so I should be able to hook up the pictographs on the planet management screen that show the production values (military, social and research) at some point when we get back from the holidays.
I started working on the trade screen so that we could get some diplomacy back in the game. Apart from the popups associated with the trade screen, I have all the code moved over from the GC1 trade screen into the new one. It was mainly a matter of copying over functions and changing anything that referenced IDs from the old one, since the new code handles control IDs differently. I'll need to run it in game a few times to make sure that I got everything, though.
The next thing that I'll be working on (assuming something else doesn't come up) will be the Domestic screen. Once we have the Planet Management screen in, we'll want to see the new method for calculating production in action.
Merry Christmas Everyone!
