Duke Nukem Editing Project tutorials
Prismed 1.0 & 1.1

Please be warned and advised that learning prismed will be time-consuming and frustrating. A lot of what you learn should come from experience and patience. But there are already alot of answers to basic questions in threads on the 3drealms forum, and in the other tutorials. It will probably take a few months, at least, to get up to working speed with this editor, so if you cannot commit to the time and frustration, do not try it.
To set up Prismed properly:
Then, click "build and run" the map. It has examples of setting up an auto-game track, a mover entity and a logic entity, plus some other things. See what it shows and then return to the editor.
Then, minimize(don't close) that window and open another editor window for a new map. Switch between the two maps and build the map exactly the way it shows in the group hierarchy, starting with the top folder and the properties of "CSG starting with" solid block, and just work your way down, studying all the properties of the various brushes and entities, and the structure of the files(subfolders, children, etc.)
When you get it completed, go to the main file menu at the top of the window and click "Check map for errors..." or the shortcut "F12". This will tell you if there will be any problems with your map. CHECK YOUR MAPS FOR ERRORS BEFORE YOU BUILD AND RUN THEM, ALWAYS and you will avoid a lot of crashes.
Also, before running maps, turn off any texture modes you might have on for the 3d view, because these modes can crash the editor(more so when you levels start getting really large).
Finally, save your work often so that if the editor does crash, you will not lose all your current work. Be sure to change the map name when you first click Save as...!
With this method, you can work through all the demo maps and learn what you need to make a fairly complicated, playable map.
Of course, when questions arise, search the forums and THEN post a question.
I hope you keep working on maps. Good Luck!
