All this refactoring, just to resolve#162. Specifically, it engages savegame events not at level load (except for savefile start) but on level completion, just after you've gotten all the intermission bonuses but before the intermission actually starts.
Also fixes a never-before-discovered bug where if the titlemap has LF_SAVEGAME, your save file will be overwritten upon returning to the title screen. This game is a mess of hacks, I swear...
One unintended side effect: It may actually be faster in some speedrun circumstances in mods with cutscenes to complete the map, exit back to the title screen, and reload the file. It's a common feature of optimal runs in games with cutscenes, though, and Marathon Run has a toggle for cutscenes, so I'm not particularly bothered.
Basically a dedicated Record Attack-like experience for speedrunning the game as a continuous chunk rather than ILs. Has several quality of life features.
Benefits include:
* An unambiguous real-time bar across the bottom of the screen, always displaying the current time, ticking up until you reach the ending.
* Disable the console (pausing is still allowed, but the timer will still increment).
* Automatically skip intermissions as if you're holding down the spin button.
* Show centiseconds on HUD automatically, like record attack.
* "Live Event Backups" - a category of run fit for major events like GDQ, where recovery from crashes or chokes makes for better entertainment. Essentially a modified SP savefile, down to using the same basic functions, but has its own filename and tweaked internal layout.
* "spmarathon_start" MainCfg block parameter and "marathonnext" mapheader parameter, allowing for a customised flow (makes this fit for purpose for an eventual SUGOI port).
* Disabling inter-level custom cutscenes by default with a menu option to toggle this (won't show up if the mod doesn't *have* any custom cutscenes), although either way ending cutscenes (vanilla or custom) remain intact since is time is called before them.
* Won't show up if you have a mod that consists of only one level (determined by spmarathon_start's nextlevel; this won't trip if you manually set its marathonnext).
* Unconditional gratitude on the evaluation screen, instead of a negging "Try again..." if you didn't get all the emeralds (which you may not have been aiming for).
* Gorgeous new menu (no new assets required, unless you wanna give it a header later).
Changes which were required for the above but affect other areas of the game include:
* "useBlackRock" MainCFG block parameter, which can be used to disable the presence of the Black Rock or Egg Rock in both the Evaluation screen and the Marathon Run menu (for total conversions with different stories).
* Disabling Continues in NiGHTS mode, to match the most common singleplayer experience post 2.2.4's release (is reverted if useContinues is set to true).
* Hiding the exitmove "powerup" outside of multiplayer. (Okay, this isn't really related, I just saw this bug in action a lot while doing test runs and got annoyed enough to fix it here.)
* The ability to use V_DrawPromptBack (in hardcode only at the moment, but) to draw in terms of pixels rather than rows of text, by providing negative instead of positive inputs).
* A refactoring of redundant game saves smattered across the ending, credits, and evaluation - in addition to saving the game slightly earlier.
* Minor m_menu.c touchups and refactorings here and there.
Built using feedback from the official server's #speedruns channel, among other places.
This fixes some issues with a custom character tested during netplay, which did not have SPR2_WAIT sprites and therefore fell back to SPR2_STND sprites. Unfortunately, the fact they used SPR2_STND instead meant the sprite2 was not synced at all!
(oddly enough, this actually revealed some secret file dependencies previously included via r_things.h! I also needed to include d_player.h in r_skins.h itself it seems)
This is accomplished by simply preserving
the player's body after disconnecting.
Bodies will despawn after the number of minutes
specified by the "rejointimeout" console variable (float).
A value of 0 disables the feature completely.
Clients rejoining are identified by their IP address,
and may rejoin even if the server is full or joins are disabled,
for as long as their body remains.
From a technical standpoint, when the user disconnects,
the player they were controlling does not leave,
the underlying player_t just keeps working normally,
except it does not receive any input anymore.
When the user reconnects, they are simply "relinked"
to their player_t.
Those "soulless" players can be identified through
their "quittime" field, which is the number of tics
elapsed since the user disconnected, or zero
if still connected. "quittime" is exposed to Lua.
