* Prevent an infinite quantity of Emeralds being spawned when P_GiveEmerald is called while a MP Special Stage is in session (resolves#347).
* Fix FuriousFox's ridiculous timer on special stage spawn (mentioned in the comments of the previous issue) by correctly marking spectator players in special stages as finished, and preventing the underflow.
"precipprops" lets you create a new precipitation type by picking a mobj type to use, how many random states it has, and flags for effects such as thunder/lightning. Seesound on the mobj type sets an ambient sound (like rain drops) and mass sets the sound's frequency in tics. This could open up the possibility for SOC/Lua Weather options later.
* Expose this via additional upper-16-bits flags of A_FlickySpawn.
* Use this to make Snailers not spawn their flicky inside the wall they're attached to.
* Make the behaviour of Egg Capsules more consistent mechanically regarding the flicky spawning, using the above as one relevant element.
Make the wall transfer while spinning PF_SPINNING|PF_THOKKED. This:
* Prevents PF_MULTIABILITY players from using their ability after a wall transfer.
* Has a more specialised case which allows players to roll after having wall-transferred while spinning.
* (side effect) allows modders to apply PF_THOKKED any time for more controllable spinning.
* Tweaked to use new sprites.
* Jet fume behaves much closer to Lach's wonderful work.
* Instead of clobbering tracer to spawn powerup overlay, use hprev.
* Change timings. One second less to charge up, but two seconds less to spin them out.
* Remove terrible pinch overlay in favour of new dashmode-mimic flashing.
* Add an alternate DEMOMARKER for ending the Metal Recording on death, which kills the Metal object as well.
* Add some more relevant exceptions to the "most objects are removed when touching a deathpit" thing, primarily for the sake of ghosts and Metal playback.
* Add height changes to demos and Metal playback (to properly place thok aura relative to object).
* Fix followmobj recordings in reverse gravity (done via more strenuous flag setting + info height serialisation).
* Make RA ghosts fade in from start tic, and go colorized on their final one.
* Fix thok auras potentially doing bad things if they're set to MT_NULL.
* Add sprite change support to Metal playback.
* Re-enable some stuff I previously disabled for Metal recording/playback.
* Make ALL objects spawned with skins properly acknowledge that their spawnstate's frame is a sprite2, rather than just specific objects.
* Fix placement of Metal Sonic fume in reverse gravity.
* Since not backwards compatible with the previous test build, increment DEMOVERSION again. (Don't worry, we've got like 65524 more versions allowed before we run out of possible DEMOVERSIONs...)
* Make the skin to record with Metal rather than Flesh Sonic. (Allowed even if not unlocked!)
* Make the object that plays back the recording actually use the Metal skin, rather than just a seperate spriteset. (The boss will still need the spriteset, though.)
* Actively record the player's sprite2, frame, and followmobj, just like regular ghosts do.
* Disable dashmode while recording, for a fairer race.
* Fix a probably long-standing bug where, while recording, being "hurt" would get Metal stuck in pain frames until they physically left the area of hurt.
* Always start Metal recording in wait frames for bonus taunting.
Other relevant changes:
* Increment DEMOVERSION *again*.
* Improve the Record Attack ghost followmobj recording to accomodate Metal's jet.
* Increase the datatype width of spritenum_t read/write for Record Attack ghosts because SUGOI 4: Back With A Revengance will probably also use more than 255 sprites alone.
* Return to standing frames (or prolong them if you're in them, rather than going to wait frames) if the player rotates on the spot with enough force.
* This was specifically done *for* Metal recording, but I decided it looked good enough to enable all the time.
