User:Alex the weeb/Physics update effect

The physics update effect occurs when one or more of a fighters' physics (e.g air speed, fall speed, gravity etc) is updated, while they are in the air, resulting in unusual results. Usually, this will simply override some temporary physics adjustments caused by special moves, if said adjustments were still in effect when the fighter's physics were updated. In some cases, this can result in bizarre or unexpected outcomes. While Inkling's Splat Roller used to be able to automatically trigger this in many situations, it no longer does for some of them. The following is a list of cases of this happening that I have found. All examples were tested using an Undamaged Speed ↑ Spirit set.

Note: the listed effects are based on physics being updated on the optimal frame. The later this occurs, the weaker the effect tends to be.

Fighter	Circumstance	Effect
Most fighters	Special fall	The fighter's regular air speed and air acceleration are restored, overriding the temporarily reduced values.
Most fighters with counters	Counters	The fighter will fall faster after activating the counter, due to the increased floatiness being overridden.
Link	Spin attack	Link will gain less height and start falling sooner, due to the temporary gravity reduction being removed.
Samus	Bomb (Morph Ball)	Samus will gain slightly less height and start falling slightly sooner. Her drastically increased air acceleration will be removed as well.
Fox	Fox Illusion	Fox will drop much more quickly during the ending lag in the air.
Fox	Fire Fox	Fox will bounce a slightly lower height off the ground when crashing into it.
Pikachu	Thunder	Pikachu will start falling during the discharge, rather than floating upwards until the animation ends or is cancelled. If Pikachu hits the ground during this time, the floating will reactivate.
Luigi	Special fall	Luigi will revert to his own fall speed, rather than using Mario's.
Ness	PK Flash	Ness will lose his reduced gravity while charging in the air.
Ness	PSI Magnet	Ness will lose his reduced gravity while holding in the air.
Peach	Parasol fall	Peach will revert to her normal falling speed, losing the floatiness of the parasol.
Peach	Peach Bomber	Peach will revert to her normal falling speed and gravity, falling faster than usual.
Bowser	Whirling Fortress	Bowser will lose his reduced gravity, and fall much faster during the move.
Bowser	Bowser Bomb	Bowser will revert to his normal gravity, instead of slowly floating upwards during the startup in the air.
Ice Climbers	Belay	Popo will fly much higher. Notably, the game cancels all of his vertical speed as soon as he enters special fall.
Ice Climbers	Squall Hammer	The Ice Climbers will no longer fall incredibly fast if they do not mash.
Sheik	Vanish	During the initial jump, Sheik will gain more height, but then begin falling instead of hovering until the teleport activates.
Sheik	Bouncing Fish	Sheik will gain more height from the jump.
Zelda	Nayru's Love	Zelda will lose the floatiness granted by the move.
Pichu	Thunder	Pichu will start falling during the discharge, rather than floating upwards until the animation ends or is cancelled. If Pichu hits the ground during this time, the floating will reactivate. Triggers automatically using Undamaged Speed ↑ at 0%.
Falco	Fire Bird	Falco will bounce up higher when crashing into the ground.
Young Link	Spin Attack	Young Link will gain much less height and start falling sooner.
Ganondorf	Dark Dive	Ganondorf will gain less height, and start falling sooner.
Mewtwo	Teleport	Mewtwo will start falling much sooner when re-appearing. Mewtwo gains less height if he teleported upwards.
Mewtwo	Disable	Mewtwo will lose the floating effect from the move.
Game & Watch	Fire fall	G&W will lose the reduced falling speed from the parachute.
Meta Knight	Mach Tornado	Meta Knight will begin falling sooner, and will have heavier physics overall.
Meta Knight	Drill Rush	Meta Knight will begin falling sooner during the jump on the activation.
Snake	Cypher	Snake will accelerate faster upwards, and reach a higher top speed.
Lucas	PK Freeze	Lucas will lose the floating effect when charging the move in the air.
Sonic	Homing Attack	Sonic will immediately stop rising while charging.
Sonic	Spring Jump	Sonic will gain noticeably more height from the jump.
Sonic	Spin Dash	Sonic will gain noticeably more height from the jump, and will be much floatier, akin to the move's physics in Brawl.
King Dedede	Super Dedede Jump	If his physics are updated before the jump, Dedede won't rise as far before the jump. If updated at the start of the jump, Dedede will gain far more height from the jump.
Lucario	Extreme Speed	Lucario will be noticeably floatier after the dash, and thus will gain more height if aimed upwards.
Toon Link	Spin Attack	Toon Link will gain noticeably less height, and start falling sooner.
Wolf	Fire Wolf	Wolf bounces higher, you know the drill...
Mega Man	Rush Coil	Mega Man will jump noticeably higher.
Wii Fit Trainer	Header	Wii Fit Trainer will gain less height, and start falling faster.
Wii Fit Trainer	Super Hoop	Wii Fit Trainer will gain less height, and start falling faster after the hoops fly off.
Palutena	Warp	Palutena will be floatier when re-appearing, and will gain more height if she's aiming upwards.
Pac-Man	Pac-Jump	Pac-Man will gain considerably more height from the jump.
Pac-Man	Power Pellet	Pac-Man will accelerate downwards more quickly after eating the pellet.
Pac-Man	Hydrant	Pac-Man will be considerably floatier when dropping the hydrant.
Shulk	Back Slash	Shulk will be noticeably floatier, and won't fall as fast when descending.
Ryu	Focus Attack	Ryu will lose the floaty effect while charging Focus Attack.
Corrin	Dragon Lunge	Corrin will jump higher.
Ridley	Wing Blitz	If Ridley's physics are updated during the dash, all of his vertical speed will be cancelled, while his horizontal speed won't.
King K. Rool	Propellerpack	K. Rool will gain slightly less height.
Incineroar	Darkest Lariat	Incineroar will lose the floating effect from the move in the air.
Piranha Plant	Piranhacopter	Piranha Plant will gain more height.
Hero	Swoosh	Hero will gain more height. The amount of extra height varies depending on which version is used.
Mii Swordfighter	Hero's Spin	Mii Swordfighter will gain noticeably less height, and start falling sooner.
Mii Gunner	Lunar Launch	The move lives up to its name.
Mii Gunner	Cannon Jump Kick	Mii Gunner gains noticeably more height.
