Good news! I decided to pick this up again, and I've made good progress with the graphics. Luckily I found the complete spriteset, so I've pretty much finished all the graphics! There's not much to show though, but I've changed the entire codebase, added all the graphics, and improved some things. I have good hopes the speed will be above 10FPS, which was my original target. This week and the next year (heh, that sounds cool
) I will work on displaying the map, buildings, units, and after that the actions, like fighting, moving and whatever. Stay tuned!
As you see here, there's a black border around the map. I will write some code to make it pretty much fullscreen, except the top bar with the resources and population, and a bar at the bottom with some key actions.
