Since the people at <a href="http://sf.net/projects/xblast2003">XBlast 2003</a> are doing a complete rewrite of XBlast, we're not going to continue developing an editor for XBlast TNT. If they don't add an editor to XBlast 2003, we might write a patch for that. But for now, nothing new will happen here.
I've decided to stop coding on xal-edit (the GTK+ level editor), and instead write a patch for XBlast that adds an internal editor to the game itself. I'm calling this XILE (XBlast Integrated Level Editor, pronounced "EX-ail").
There is now some code in the CVS repository. Don't use it, the map editor isn't implemented.
