Now this was magnitudes easier than the EDuke menu - NBlood's menu is actually clean and usable code but still nothing compared to a unified menu system.
This was only a crutch to let the input interface work with the original menus.
Now that the one in Blood is gone, all the conditions are no longer relevant. (Shadow Warrior never got far enough to implement this)
This was some meticulously preserved relic of bad old DOS times used to block OS facilities to close an app.
Since this has been worked around at a lower level already the variable was essentially without function but some quite bad code depended on it.
This mainly means being able to use the generic font.
This also adds more generalization to the menu sound handling, plus an option to turn menu sound off. This is motivated by the pig sounds which RR uses in the menu.
* removed some redundant functionality (e.g. Shift-F5 to change - use the console for that!)
* removed a few more leftover parts of the old music system
* savegames should not do more than resuming the music at the point of saving. (DN3D and RR only so far. Blood to be done.)
* handle music enabling/disabling in the backend, which simply knows better what to do. This was only working in the menu, so changing the CVAR had no effect.
* implemented single image screens
* implemented skeleton of the image scroller
* added RR-specific definitions to the menus (need to copy and adjust d_menu.cpp)
* added definitions for credits screens.
Not tested yet!
* Added a JSON-based header to the savegames so that the unified menu can read from a common data source.
* moved loading and saving of frontend independent data to the wrapper so that support is automatic.
I have no idea how this is supposed to work, but all it does is create corrupt images, so for now it reverts to the software renderer which generates working 320x200 images.
Since the code is extremely volatile I changed the setup so that the save is a zip file with the regular snapshot plus all added data as separate entries.
This allows compressing everything properly without savegame breaking interference.
Blood does not yet load its savegames, need to check.
Conmsidering how hard it is in Duke Nukem based games to modify the level music, there is now a setting for this in mussetting.txt to make the job easier and even allow setting level music in Redneck Rampage without replacing game data.
- draw fullscreen blends below the console.
- moved all mouse event processing out of the SDL backend to D_PostEvent.
- removed all remaining code for dealing with mouse buttons directly.
Unfortunately necessary because Ion Fury savegames store 120 GB(!!) of data, mostly zeros.
Unlike the old method, this compresses the entire savegame as one block using a ZLib stream so it should be a lot more efficient now.
