Add auto save feature

[ceski-1]

details

Simple behavior:

• Auto save at the beginning of a map, after completing the previous one
• Menu item under General > Misc
• Off by default
• Disabled for demos and multiplayer

Example of completing a map, the next one loads, then the game auto saves (note the game saved. in the upper left corner):

save_autosave.mp4

Notice that the save description is the default one with (Auto) appended.

If On Death Action is set to Last Save, the auto save will be loaded if it's more recent than the regular save in the player's current save slot. That's usually the case when the player forgets to save on the current level, and that's where this feature is most helpful. Example:

death_use_load_autosave.mp4

The first save slot on the first save page is reserved for auto saving. The auto save is kept separate from woofsav0.dsg in a dedicated file named autosave.dsg. Toggling the "Auto Save" menu item toggles which one is shown.

preserve_existing_saves.mp4

The auto save slot is enabled when using the regular load menu, but disabled for the regular save menu. This is so the player doesn't try to save to that slot only for the save to be replaced by the auto save later.

Quick saving and quick loading can't select the auto save slot either, so that those keys can continue to function independently.

Great work, thank you!

I don't like that autosave hides the first normal save (woofsav0.dsg) in the menu. Is it possible to increase the number of save slots in the menu if autosave is enabled?

Okay, added a separate auto save slot that appears in the load game menu only (like other fps games):

separate_auto_save_slot.mp4

Thanks, works great!

I really like this feature, how about enabling it by default?

Okay, enabled by default.
