Yes, that's right, ship constructing is now in the game! You can select a ship design to build, allocate construction points to it, and hit turn and build it! If you change to another design when the ship is partially built, it transfers the construction points to the next design (Yeah, it's unrealistic, but hey, it keeps things simple code-wise)
Here's a screenshot of the ship construction:
However, I discovered several bugs when I implemented this. Each confirmed ship design overwrites all other ship designs except for scout. The left arrows on slider bars for planet screen stopped working when I implemented this. And maybe some others that I haven't discovered yet.
The next release is getting nearer! Just need to squash the above bugs (there are a lot of other bugs, but those are the most serious), and check that ship design screen is indeed done. Speaking of ship design, here's the "final" (final meaning for now, until I get professional looking art :) ) ship design screen:
Special thanks goes to EmP for suggesting an improved layout for the ship information display!
