Sea Egg is majorly changed according to Mystic's ancient instructions (excepting the flying FOF rock, I cared not for fucking around with FOFs).
Specifically:
* Faster paced fight.
* Instantly travels horizontal distance.
* Fakes no longer hurt papa, and spin out like a deflating balloon when he dies.
* New attack: When surfacing, produces an electric shockwave. Replaces underwater shock. Designed for new, shallow arena.
* Support for multiple bosses in the same map distinguished by parameter.
Will upload map to fight the new battle in on the MR.
* Add more context clues to his fight, including an indicator for which laser attack is being used after chargeup.
* Make missiles able to vectorise him.
* Add another laser orb attack - vertical slice - and change the laser orb sequence to accurately reflect that horizontal is the hardest of the ones in 2.1.
* Optimise TC_BLINK, and fix an issue with TC_ALLWHITE that somehow avoided coming up in testing.
* Fix colorized bosses losing their colorization when flashing, by forcing TC_ALLWHITE.
* Remove PF_THOKKED every time a successful damage bounce occours.
* When this happens, spawn a number of particles based on thokitem at half scale! (Optimised, again, for MT_LHRT.)
* Also spawn these particles when a successful spring boost occours, as well as playing a twisted spring sound.
Also, some other related tweaks:
* Optimisations to A_VultureBlast, which was used as a base for the particle creation.
* Make the Metal Sonic boss use P_PlayerCanDamage instead of a custom, somewhat broken player damage detection mechanism.
* P_SpawnGhostMobj takes colorized into account.
* Fold Tails propeller damage into P_PlayerCanDamage.
* When performing an Attraction Blast, place the player in roll frames.
* Update all conditions preventing SH_PINK to incorporate thokitem and spinitem as well.
* Buff MT_LHRT travel distance at slow speeds.
* Re-fix chat HUD position, and make it not move in match (which it needed to do in 2.1).
* Fix HU_drawPing for the new palette.
* Change the condition for greying out players, since the current one was buggy.
* Allow for tokens on the coop MP HUD, and use the small emeralds so there's space for them.
* Fix the mapping between skincolours and name colours in new chat, specifically to take into account every possible text colour (as opposed to the port previously done, which only used the 2.1 text colours and looked like ass as a result).
* Move HUD text's anchoring to underneath STR instead of above Lives.
* Adjust chat position slightly, to take advantage of SRB2's HUD layout having less content towards the bottom (unlike Kart, where it has roughly equal).
* Fix Match emeralds not displaying while in tab rankings with all-seven invuln/shoes bonus active.
* Like Kart, remove cv_precipdensity.
* Like Kart, replace "Infinite" draw distance value with "None".
* Better thinker with more return optimisation.
* Better placement of thinking in rendering, to avoid ceiling-mounted sprite glitches.
* Re-fix chat HUD position, and make it not move in match (which it needed to do in 2.1).
* Fix HU_drawPing for the new palette.
* Change the condition for greying out players, since the current one was buggy.
* Allow for tokens on the coop MP HUD, and use the small emeralds so there's space for them.
* Fix the mapping between skincolours and name colours in new chat, specifically to take into account every possible text colour (as opposed to the port previously done, which only used the 2.1 text colours and looked like ass as a result).
* Smoothen Pity Shield animation to go with sphere's updates to Nev3r's sprites.
* Added LHRT object, designed to be summoned with CA2_MELEE.
* Gives a pink Pity Shield (SH_PINK) on same-team player contact.
* Deals damage to non-player enemies.
* Harmlessly fades into nothing when touching an enemy player, players with SH_PINK already, and players capable of applying SH_PINK to others (through non-Lua methods).
* Basically, you-know-who is the Healer of the party whenever they're around. Fun consequences for the Co-op and CTF metas.
Also, the start of my improvements to CA2_MELEE. Users of that abiliy can only damage enemies/monitors if they touch the front of the player object, but to make up for it, the player is no longer forced away from the direction of the screen at bigger movement speeds.
* Takes function(player, mo) input.
* Return TRUE for stating that yes, the player is in a state that can cause contact damage, do with that what you will.
* Return FALSE for stating that no, the player is weak and vulnerable and cannot cause contact damage, do with that what you will.
* Return NIL for allowing the function to continue regular operation.
Fills a different ideological niche than ShouldDamage - that's for determining whether damage dished between two objects should happen, this is for determining which way around damage should be dished when considering a player-object interaction.
Or, in other words, think of it as "ShouldDamage is whether damage that has been requested should be granted, for object-object interaction, while PlayerCanDamage is for whether global player properties should cause damage to enemies and monitors in the first place, like spinning, hammering or stomping."
* Move HUD text's anchoring to underneath STR instead of above Lives.
* Adjust chat position slightly, to take advantage of SRB2's HUD layout having less content towards the bottom (unlike Kart, where it has roughly equal).
* Fix Match emeralds not displaying while in tab rankings with all-seven invuln/shoes bonus active.
* Port across the additional colour translation maps, including mobj-level support for "colorized" objects.
* Make Fangboss and both Metal Sonic objects greyscale if, on spawn, there is a player in the game who is not a spectator whose skin is that character.
* Allow bosses with MF_GRENADEBOUNCE to opt out of the MF2_FRET colour-flashing tomfoolery, and give this flag to Fang.
* Like Kart, remove cv_precipdensity.
* Like Kart, replace "Infinite" draw distance value with "None".
* Better thinker with more return optimisation.
* Better placement of thinking in rendering, to avoid ceiling-mounted sprite glitches.
