I just released a new Unity Asset for making Platformers : u3d.as/2eYe

[@Tony-gq4en]

This is life saving! I thought this had to do with my monitor. You just fixed the last 8 months of my life! Thank you John!

[@LostRelicGames]

Your comment just made the video worthwhile mate!

[@Tony-gq4en]

@@LostRelicGames This video literally just helped so much! Immediately became a patron! Thank you Thank you Thank you!

[@LostRelicGames]

@@Tony-gq4en you are awesome man! I'm keep the tips coming!

[@crispy_doggo9117]

Same here! Strangely, on my 144hz monitor I had severe blurring behind my character, and on my second 60hz monitor, it was just a jittery lag on the movement. This fixed both of them!

[@klaus117gaming]

Sometimes I run into funny problems in unity and it drives me crazy. This was one of them, thanks for the save man. Would be awesome if you can make more videos on common problems like this

[@NobSwitch]

This could have been a 10 second video. But you take almost 5 minutes to fully explain to us everything. I wish you were my university professor

[@carlosjesus4453]

Oh my God, thank you. I've been unable to fix that error for months and have read dozens of posts saying it was a problem with my screen. A million thanks. You don't know how happy you've made me.

[@lodesa]

Uggghhhh... I could have saved myself 3 hours of frustration if I had just watched this sooner... Thank you so much for this!

[@lucasburford7881]

Literally saved my life, my character was jittering so bad when I moved them, this totally solved it. Thank you so much, genuinely! Definitely earned a sub :)

[@0Baita0]

I literally, deleted, my ENTIRE rigidbody character controller the other day and reprogrammed one that didn't need a rigidbody! I'M GOING BACK! THANK YOU SO MUCH FOR THIS!

[@barankavlak]

You are a life saver sir. I was almost lose my mind because of cars shaking. Thanks!

[@RickRodGaming]

THIS IS THE ABSOLUTE BEST!!! This fixed all my jittery nightmares. You have no idea how long I been looking for this solution to no avail, till you came along. Awesome video!!

[@assassin_squid]

I thought this issue had to do with my poor networking skills. You just saved me from so much pain. So glad I saw this before i tried to fix it myself

[@melvmay]

I want to start by saying that this is a great video! Regarding interpolation though; Interpolate doesn't change the simulation at all. Indeed, internally the simulation knows nothing about intepolation. Interpolation only applies to the Transform! What does change is that per-frame the Transform isn't going to be the same as the body but instead moves from the previous body position to the current body position so it's always lagging behind the "real" body position. This means that Rigidbody2D.position and Transform.position are not the same with interpolation. This is important if you're using Transform.position/rotation for queries or other calculations. The Transform pose therefore isn't the same as the Rigidbody2D pose when interpolation are on. Body position is the authoritative pose but it's only updated when the simulation runs. If you are seeing something different happening with this option on then some script is performing work based upon the Transform pose and not the body pose. Interpolation is always behind the body position but extrapolation is always ahead of it because per-frame the Transform is set from the current body position to the extrpolated body position in the future based simply on its velocity i.e. predictive whereas interpolation is historic from last to current.

[@LostRelicGames]

Great explanation Melvyn! Thanks for taking the time to delve into the underlying mechanics, insightful!

[@melvmay]

Wow, this should be a Unity essentials. It's a sin that this is not a widespread knowledge. Thank you so much for this.

[@kanaip5028]

Amazing! This really did the trick for me! It's my first time using Unity for a game dev class and I encountered this issue with my character's walk cycle a couple weeks ago. Since then, I've been re-animating in AfterEffects and testing in Unity with no success. I even tried moving around keyframes in Unity, which also didn't work. This was perfect, thanks so much for the quick tut!

[@duanenso_freestyle]

I always wondered why Interpolate watching these tutorials on these FPS controller things. They always say - do so, but never really states why. Super Duper helpful, subscribed instantly!

[@RajThakkar99]

Thanks mate! This did work. I have gone through several forums and posts with different solutions but this fixed it for me! You are a life saver!

[@Oto_joolix]

OMG THAKKKKKKKKSSSS, i've sat here now for 2 days, asking myself what i did wrong in my life xD and no one had an answer to this accept for you!! Now why player isn't jittery anymore, love you! thank you verry mutch :)

[@AndersonLuiz-zl4hm]

Sir, you saved my life. Thank you so much for this video!!!

[@Smumbo]

In order to save on performance, could there perhaps be a system where the interpolate setting is toggled for rigid bodies that enter a certain radius around the player? That way we don't waste performance on further away objects since we might not care about accurate physics simulation at a distance. Though I'm also wondering if toggling that interpolation setting at runtime might be a performance hit in and of itself.

[@LostRelicGames]

That's a very interesting idea! And i would say probably yes. Will test this out. Great idea mate

Thanks man. It really was a pain in the butt...

[@woltwa]

the GOAT

[@LukeHwarang]

How peculiar. In my case, I had to set the interpolate to "none" or "extrapolate" to stop my jittering effect. However I'm making a 3D game with 2D sprites, the jittering was happening when the player tried to walk throught walls. Anyway this video gave me the idea to mess with the interpolate options and solved my problem. And also now I've learned a new thing. Thx mate! o/

[@ash7324]

Got it in one! Nice on bro

[@Wayloz]

Super helpful information! However (and I don't fault you if you don't know) in VR this isn't solving my issues. Currently I have a charactercontroller than handles my player movement, and from what I understand when I grab an object, it follows my hand by using my controller's velocity and applying velocity to the object. When walking around the object trails behind for a split second and then catches up with my hand. I figure this is due to me used a moreso kinematic movement system and there being no directional velocity for my controller when moving so it guesses and catches up. Though multiple things I said there could be wrong, I'm not the most informed but I'm willing to learn. Thanks again!

[@theorionfrontier2742]

Really good tipp, thank you for that !

[@pedromartins9049]

Finally, an answer to my prayers

[@stevencraeynest7729]

Another thing that causes jitter is when you apply forces in Update() rather than in FixedUpdate(). Which is annoying, cause you actually have to read input in Update(). So if you need to apply forces based on input, you need to store the input in variables in Update(), and then use them in FixedUpdate() to apply forces.

[@ijidau]

This isn't the case if you use the new Input System which is event based and does not rely on Update() polling.

[@nerdimesrobcou9529]

It can be too because camera movement is updating in Update() and the position of object is updateing in FixedUpdate(). If you put camera into FixedUpdate() it should work too.

[@sinho113]

wow, i tried the fix on the video and didnt work until i saw your comment it it worked first try ;D thanks bro haha

[@aleksandraopacic2901]

I can second that, wow, I also tried this and many many other solutions that didn't work and it was the camera all along, lifesaver thank you!

IDK if using velocity as animation trigger was good idea, but this seems to help when I need to determine if the player stays still.

[@ahmedsiddique2998]

ok i used interpolation i got a hint from some forum but im applying it to an enemy ragdoll and some time my enemy ragdoll becomes glitchy u know like a monster extra stretching every body part do you have tips how to fix it ? im also using timescale its an action camera + body hit in slow motion I hoe u understand

[@jasonazevedo2881]

you are a GOD my friend!

[@_g_r_m_]

Interpolation makes my player ignore colliders and also doesn't solve the jitter, weird, glad for the ones who worked for

[@pcernuska]

Try to extrapolate first if it would work fine and in case it is less resource hungry.

[@cazterk]

easy does it, this video is golden thank you

[@appsyz5103]

Thank you!

[@JK96CZ]

I'm still a beginner, so it may be trivial, but I've got one question about that. If you use it on more things, it has a performance issue, but does that apply on currently moved objects or overall? Let's say I would have 100 of these wagons in my level, each with interpolate, but they could be only two at a time moving, cause they are spread around the whole level and there is no way of getting more than two at a time to move. In the second example I would have, let's say 20 objects with interpolate but all of them in the current scene and moving. Which would hit performance harder ?

[@codycanipe4415]

wow, nice one, thanks man!

[@dannychatzi4834]

[@fruitfunfitness3584]

I suspect turning the camera update mode to fixed update could also be a potential fix.
