I don't know whether anyone still cares about an editor, but since GC2:Builder seems like it's not going to be updated I decided to finish an editor that I started a while back. I'm hoping to have an early version posted either today or tomorrow.
As it stands now, it is more limited than GC2:Builder, but I'm hoping to have it at that level before too long. That said, there are a few things that I think my editor does better than GC2:Builder. Most notably, I have a full 3-D display, and the ability to simply click and drag objects in order to move them.
At the moment, it is purely a map editor and has no tools for scenarios or campaigns, although they are intended for future release.
The major areas I will be focussing on for future improvements are as follows:
Scenario/Campaign capability
Using the game xml files rather than hard coded data (ship placement will probably implemented until this is done)
Random map generation
Of these, my first priority will likely be either random maps or better xml use/ship placement. Also, since there were a couple things that I was learning as I went along (especially directx), I am going to have to go through and redo a lot of the old code. After that is done, I will go ahead and release the editor's code.
Anyways, just giving you a heads up. Look for this somethime over the weekend.
