2.1 vs 2.2 Physics Comparison

[@Fanro3]

the 3x speed difference is smaller than the 2x one, the former is "massive" while the latter is "big"

[@JUSTREGULARSCREAMINGAAHH]

massive?

[@valacejo]

the problem is that so many hard levels are built on the previously existing physics that even when you change them very little it can still break some levels

[@tzbq]

didnt robtop add an option to keep the old physics which is enabled on old levels?

[@7rodo]

​@@tzbqslopes aren't part of the change

[@tzbq]

@@7rodo oh

[@zephicules]

​@@7rodo why though? if you add an option that literally enables old physics why not make it apply to everything that has changed?

[@7rodo]

@@zephicules hardcoded changes

[@wenelol]

New physics shouldn't really affect older levels since they won't have 2.2 physics enabled. If you go to a level that you made pre 2.2 and check out the legacy options you'll find out that "Enable 2.2 Changes" and neither is any of the other legacy options meaning that pre 2.2 levels will have 2.1 physics.

[@sgjoyder2890]

So if woogi does this to the windy landscape the issues will disappear?

[@yesno1085]

But then why are there reports of broken levels everywhere? Hz bug?

[@wenelol]

@@yesno1085 Probably caused by the physics being centered around 240Hz in 2.2 from what I've heard. Didn't think that it'd apply to levels with the legacy options not checked.

[@lumi2030]

all of these options are turned off for all pre-2.2 levels by default. it's just that not all physics changes are accounted for by those options. and robtop must fix it.@@sgjoyder2890

[@lessgenericname]

the legacy options don't cover all of the physics changes

The reverse gravity ship in 2.2 handles poorly

[@PizzamemesOfficial]

in 2.113 I made a level called impossible and it had a few hard jumps, but now in 2.2 it is actually impossible.

[@MaxwellCatAlphonk]

Both on 60fps, but 2.1 on 60tps and 2.2 on 240tps That is literally the only physics change afaik just 240tps regardless of fps

[@foodwav]

a part of the issue may be that you have tested at 60fps. 2.2 physics run at 240hz. So the test should be done at 240.

[@halcyK]

i'll look into this

[@F6347_VR]

old gd 2.1 physics were the same that your FPS, so FPS = TPS back then. New gd 2.2 physics are ALWAYS 240tps. so TPS = 240

[@raghav13254]

yes but like why is the slope physics changed? how does the tps make the slope physics different, and is there any way that robtop can fix this

[@RealGeneral]

not quite true 2.2 60hz registers your inputs 60 times a second while 240hz does it 240 times a second. however any fps now updates icon position 240 times a second unlike 2.1, in which it would update position four times per tick regardless of fps (meaning 240 position updates per second on 60hz and 960 on 240hz for example)

[@asdfoifhvjbkaos]

@@RealGeneral so some clicks are still possible on 240hz but not on 60hz?

[@Stupid95477]

You can disable 2.2 physics in the editor so… yeah

[@talentlesscommenter1329]

It doesn’t fix broken levels from my experience making copies of levels and disabling.

[@vent2482]

how, pls tell me

[@ERRR0RR]

You should also compare cube jump and cube double jump heights between 2.1 360 FPS and 2.2

[@GalacticCollapse]

He should've added an option to turn on "Legacy Physics", otherwise certain 2.1 levels are unbeatable.

*cough* windy landscape *cough*

[@Niteshade_]

They are fine

[@voist4927]

i dont undedrstand,why dont robtop just add the physics to platformer levels?

[@baggelissonic]

They had to change the physics eventually in normal mode as well. There was fps discrepancy. Robtop fixed this and now the physics are the same regardless of your framerate.This sounds like a win to me.

[@DerSpechtGD]

i think legacy physics could be an idea to fix that issue but i dont know if it would work that easy

[@RandomGeometryDashStuff]

some levels impossible to get coins because player can't dual after level ends in 2.2

[@nguyenhuycongthanh3411]

I understand why some levels are impossible

[@cheesyisgood]

so 2.2 made my level impossible, so i verified a possible level but somehow i verified an impossible level too

[@slavicmonke]

I would just add a button into the editor like "Old physics" and all levels made >2.2 are automatically gonna have the feature on

[@F6347_VR]

idk if you knew but these differences are cause because he is playing at different frame rates, as robtop confirmed that now all physics run on 240fps, so actually, the 2.1 he was playing at 60tps, and 2.2 he was playing in 240tps.

[@slavicmonke]

@F6347_GD oh that makes sence now, I mean it still would be a good feature imo

[@tntblast500]

@@F6347_VR How do people get this wrong so much? 2.1 used to ALWAYS do 4 physics steps per frame. So 60fps in 2.1 was 240tps and 240fps in 2.1 was actually 960tps. Rob explained this himself in the gd discord. Now 2.2 always used 240tps regardless of framerate so 2.2 should be equivalent to 60fps in 2.1 NOT 240.

[@MarioModder64]

People say theres not an easy fix, which is true, theres not an easy fix ANYMORE. rob could have gone the mario maker route, where levels made in 2.1 keep acting like they're in 2.1 and new physics, features and such take effect in 2.2 created levels.

[@tntblast500]

The thing is, he kinda did. But for some reason the new slope physics is global. Still, there technically wouldn't be anything stopping him from reimplementing the old slope physics as a legacy option but at this point it seems we'll just have to bugfix broken levels.

[@MarioModder64]

@@tntblast500 I agree. I personally wouldnt be against if Rob Himself went into these old accounts and shifted a spike half a tile to the right, or made a jump pad an nudge to the left, to fix things like the fps bugs and new physics being a problem in old levels.

[@N3bulA_]

@@tntblast500 sorry, late reply. Considering SOME but NOT ALL of the 2.2 physics changes have legacy options, it seems that the slope jump mechanic being changed as well as some other stuff like dual gamemode boundary hitboxes and green orb clipping were entirely unintentional, and thus RobTop would've had no way of knowing how much his code broke older levels. By the time he did, he was already much too far into the update to feasably revert it. It should be pretty common knowledge, when you fix bugs/compatibility issues, more bugs will always appear. RobTop MIGHT try and revert these changes by adding legacy options but I wouldn't count on it. We'll just have to see how things pan out.

[@solarpaneI]

its just different. not worse or anything. once ppl adjust we’ll forget abt it

[@shisu7213]

reverse ship has now been made to have physics like normal ship. problem with that is that it has been heavier than normal ship for so many years now and nobody wants to get used to something else. it changes the difficulty of levels in the game

[@thedepressedalcoholites5702]

theres options to change 2.2 changes for 2.1 levels but i dont think this physics change is one of them

[@thedepressedalcoholites5702]

also 2.2 physics run on 240hz so i think its 60hz vs 240hz physics but 2.2 might have changed the physics in a way too

[@thedepressedalcoholites5702]

ahh ok i see you already found this stuff in the other comments

[@alfathrafathra4608]

Why did robtop change the physics in the first place?

[@KwikBR]

because before the physics was different depending on computer, now its same

[@KUSOKSAFKONN]

by the way did you know that now the level "dynamic on track" from ruby pack is impossible due to new physics, therefore 160 coins achievement is impossible too?

What about 4x speed and 240 fps? Also I’m pretty sure that the higher the fps the faster the game runs (by micro margins) and in 2.1 physics just break at higher fps

[@themilkcat6718]

The game has a physics tick rate of 240 per second, The only thing fps determines is input delay, which I assume is a technical limitation.. The big thing about the physics changes is to make them consistant.

cant robtop just revert the physics back to 2.1 while there isnt many 2.2 levels

nope, its caused because of new physics FRAMERATE. its now ALWAYS 240tps (tps is framerate for physics.)

[@tntblast500]

Why would Robtop revert the physics? It's clear he had a lot of problems with 2.1 physics which is why he changed them in the first place. He wants every level going forward to use the new, consistent 2.2 physics. Now why he didn't do a better job with preserving the legacy physics for old levels ¯\_(ツ)_/¯
