to answer the question, type set game_mode_backup 0 in the editor command window and hit enter, go ingame, create the save (quick or regular), exit the editor (NEVER save your map in the editor after doing this) and you can load the save with the regular exe.
This explains saving from 'game mode' in the editor, and then apparently loading it in SS2 as if you were an end-user... but I don't get how to re-load it from inside the editor. Obvious guess would be, enter 'game mode' hit escape, go to load, and load the saved game. However since we're talking about a pseudo-game inside the editor I can't assume it acts the same way. Is that how it works?
1. load level of interest in editor (say level 3)
2. ALT-G
3. ESC > SAVE
4. ALT-E
5. Exit editor without saving
6. Re-load ShockEd
7. Load level of interest in editor (level 4)
8. ALT-G
9. ESC > LOAD
10. Load save game
Like that?
Actually the best way I see this working is to save the game in the level prior to the one you're currently screwing with. So a save game for level 3 would be good if you're working on level 4. That way, whatever you change in level 4 doesn't get undone when you load the save game. The save game merely offers an entry point into level 4 that saves you a ton of time getting to.
ZB I get what you're saying about resource caches and cheat codes but sounds clumsy and stapled-together to me. Trying to anticipate all the prerequisites for a level and making special secret provisions for them can never be as reliable as actually playing the game up to the point you're working on. And if something doesn't work, then you just exposed a bug you need to fix, which is a good thing.
