An Introduction to the Mover Plugin | Unreal Fest 2024

[@BooneyTune]

These guys at Unreal are always working hard and coming in big with new improvements.

[@jaydee499]

The presenter stated that Epic wants developers to use and provide feedback on Mover. *Please provide thorough documentation* so us beta testers can dev with the system as intended. Epic has historically provided inadequate documentation (see Gameplay Ability System), but there is always time to change! Something along the lines of the UEFN documentation would be nice. “Just read the code” documentation leads to chaos.

[@Madlion]

Just read the code is actually the best doc u can have using Unreal

[@xaby996]

😂 keep dreaming! 😢

[@TheBlackGamerPT]

People have been complaining about capsules and animals incompatibility for over a decade. Glad the devs finally decided to address this! Im also very excited about the AI implementation since this would most likely allow us to put more npcs on screen or create bigger armies with less limitations. Hoping for a compatible and smooth avoidance system too, since the old ones produce snappy and rigid actions. Looking forward for more updates related to this!

[@Elmarath]

I hope Epic will prioritise this. Current movement model is really hard to edit and control especially if you are working with networking. I have played around with Mover plugin and the biggest issue was the "Jitterry Movement" but they said that it is going the be fixed. Other than that I don' t really see why not to use Mover plugin.

[@coldtech06]

If you aren't going to watch the whole video, at least check out the demo at 31:41, very hyped for stuff like that to become common.

[@SomeRandomGameDev-e2g]

as a programmer, this will feel like a bigger upgrade than going from ue4 to ue5

[@Khalid_Looby]

how so? is its performance better?

[@DaDarkDragon]

​@@Khalid_Loobymaybe watch the video?

[@TheSargKyle]

Truly, this might be the solution to not needing to buy a $600 marketplace plugin 😅

[@Khalid_Looby]

@@DaDarkDragon i watched, but i dont understand how can this increase performance??

[@UsernameNULL755]

@@Khalid_Looby UE5 is not better than ue4 just performance-wise. There's loads of new tools and features that make the development of already possible things easier, and empower the developers to do things that weren't previously possible with UE4. That accounts to almost all kinds of UE4 developers - level designers, texture artists, technical artists, vfx artists, cinematic artists, animators... EXCEPT programmers. Up until this very feature discussed, there hasn't been a game changer for a programmer in UE5. 75% of the time as a game programmer, you're writing code that moves things around. This plugin will signifcantly change how you do that.

[@DevGods]

I’ve been using mover a lot and I’m super excited for what you guys have planned with it. MERGE ALL OF KAI’s CHANGES lol!

[@XxHackL363NDxX]

love you

[@sisqobmx]

Unreal Engine is revolutionazing the scene. Never seen a more straightforward yet deep and complex software like it. We're waiting on FAB 🙌🙌

[@argosbrave6415]

I will neverforget how hard it was to find the setting to smoothly replicate just changing the capsule height of CMC (a random variable on the Character class, lol). This is a game changer

[@jonathanperreault4503]

this is the specific thing i got into game dev for , fun gameplay

[@무방스튜디오]

Please make it as fast as possible. I'm so glad to this feature is actually implementing right now. Please I really want to use it

[@Aaronmac404]

The networked physics stuff has me really excited.

[@fotenks]

This is huge, especially for MP games. You had to either buy a $600 plugin or be a high level expert at netcode to do movement based things and changes.

[@prodev4012]

How soon do you think mover 2.0 will be usable with blueprints? I don't want to spend 600 for GMC!

[@mr.t0xic100]

@@prodev4012exactly, I literally just started learning it, so I have some lead-time, but nothing more demotivating than learning a week in that your game just may not be possible without hundreds of hours into learning C++ and net code. (Not that I have anything against learning C++; I do plan on learning it along the way)

[@xaby996]

​@@prodev4012prolly coming with ue6, since ue6 is gonna be all about easily made MP games.

[@ErichToven]

OMG.. I just had this issue the other day with having to use a character class. Thank YOU!

[@yveseboo5057]

The concept looks very similar to my plugin from a year ago, with major improvements. Interesting 😊

[@quackcharge]

as someone who hacked together terrible custom movement in BPs I am very much looking forward to this

[@ghettomining]

I find myself watching the silhouettes talking lol.

[@pricklyprickle]

Looks promising,

[@jxgerofficial]

I can't explain how happy I am.. Feels like a dream

[@shannenmr]

Multithreaded Movement would be a HUGE boon to UE performance if you need many AI on the screen, once you properly configure your AnimBP to be multithreaded the CMC is the next bottleneck and the main "solution" is look at using Navmesh Walking mode or lowering the CMC tick rate based on say Distance / Significance Manager.

[@shannenmr]

Thinking about Mover 2.0 potentially being multithreaded again... would be "EPIC".

[@xaby996]

Well said.

[@shannenmr]

@@xaby996 I shouldn't have said "only solution" because the other solution is to write you own Movement Component from say PawnMovementComponent and only implement the specific requirements you have and potentially even centralise it to use a "Movement Manager" type class that ticks all the the Movement Components in a CPU Cache friendly way.

[@perfectionist724]

I would like to see in some future version. Easy soft body physics

[@GlassesAndCoffeeMugs]

Another experimental feature that should be production ready by UE6.

[@joanvillora]

I only hope that I can still use C++ but multithreading (and all the other things) are welcome!

[@LeGeNdThUnDeR]

Finally, from official site, This is what I was waiting for 1 year and playing with it's experimental examples.

[@jarnine-d9n]

I just tested It and Its very jittery when i run around. I have a 4080 so its not my pc, I guess it's going to get better over time. Thank you UE team. Cant wait for 4.5. Plus I want to thank you for making every first Tuesday of the month feel like Christmas.

[@jacksonblack3809]

You need to activate some things in the project settings like resimulation and prediction.

[@JanSeliv1]

Interesting. How exactly those settings are called?

[@jacksonblack3809]

@@JanSeliv1 there are other videos on it to do with setting up Mover. But in Project Settings there are two checkboxes, one for prediction, one for resimulation.

[@jarnine-d9n]

@@jacksonblack3809 Thank you I was guessing it might have been something like that. I'll look into it.

[@JanSeliv1]

I tested the Mover plugin on the UE5.4.0 release using the provided sample map and really liked the concept. However, my client experiences significant jitter at 400ms+ ping. Given that movement is locally predicted and error correction is client-side, I'm surprised the movement looks worse than CMC with high ping. Does anyone know if this is something that will be addressed, or is it by design?

[@JanSeliv1]

I also noticed that with Mover, the client experiences rollbacks often, whereas CMC was interpolating instead. It seems like this is by design. However, I believe this is the main reason why movement on the client looks worse now. It would be great to have rollbacks with built-in interpolation for Mover

[@PhoenixTheGame]

Looks cool :D, I have also implemented mover with the motion matching sample, about 45 days ago😁

[@CXCubeHD]

This is what we need!!!!!!!

[@MetalGearMk3]

Mover has so much jitter just from running around, why is that?

[@mugabsyll5155]

Keep up the great work

[@ponderingForever]

[@yurilowell9365]

What's the best workflow for implementing your own Mover character? Preferably, I would like to make mine somewhat flexible to future plugin updates. I'm leaning towards implementing `APawn` & `IMoverInputProducerInterface`, just like the example class. I.e. `MoverExamplesCharacter` base class: `class MOVEREXAMPLES_API AMoverExamplesCharacter : public APawn, public IMoverInputProducerInterface` My class: `class MYMOVER_API AMyMoverCharacter : public APawn, public IMoverInputProducerInterface` Any advice would be awesome, ty 😄

[@3Rton]

The NPP hasnt had updates in awhile though. Is it safe to assume the chaos physics is the main replication star moving forwards or what?

[@roberttaylor4696]

I need this tomorrow lol

[@RictorScale]

wow this is awesome

[@Retro_simone]

Justin is awesome!!

[@mezzanine510]

I'm wondering if this works well with networked ragdolls, that's a problem I've been trying to solve for a while :D

[@adversionzero]

Can it support GAS (Gameplay Ability system)?

[@youseiy]

THEY ARE COOKING

[@CrisisDispenser]

Finally!

[@ECHSBACHS]

Cool!

[@BilalBliooAI]

🎉🎉🎉

[@agneesesaini6689]

No more capsule restrictions yay!

[@Khalid_Looby]

what about its performance compared to the old movement component?

[@kether8775]

Why flicker when moving? And still shaking on stairs, please fix these problems first

[@GrounddevLF]

i love you people

[@theQuickRundown]

Give us documentation, or will this be another one of those plugins where the community is supposed to figure it out on their own?

[@NoHighHighlight]

Really looking forward to this presentation, a few minutes in though, I want to tell the presenter to clear his throat and drink some water :D

[@progressivenetwork3584]

Neat

[@RogerHazelwood]

Whats about execution time? Till yet c++ ist much faster than blueprint

[@kashyapsumit]

hey I'm getting "\libUnreal.so was not found" error while android build anyone have solution please help ? i have also tried deleting some folder still not working

[@drew4286]

my question is will it work with locomotion? idk if he explains it I'm only at the start but I assume he doesn't 😂

[@NextWorldVR]

Is this question a joke? It is called MOVER...

[@ABentPaperclip]

lmao wow.

[@As_Ss]

doesn't mean anything if there is no real documentation and tutorials about anything and its not just this plugin, but everything that connects to it too its supports async physics well too bad there is zero docs about async physics in the engine this is absurd instead maybe of doing speeches, can u pls invest in making proper documentation and more advanced tutorials of how to modify more in the engine the same was with the chaos physics talk in fortnite the undirected graph and other things show us how to use that stuff, samples, tutorials there is almost none more advanced for chaos it was less of an issue when there was physx as it had documentation from nv but now its just chaos and no more advanced docs...

[@Clockwork0nions]

Of course there is no documentation, they’re still building it 😂😂😂

[@As_Ss]

@@Clockwork0nions yeah, for like years...

[@Clockwork0nions]

@@As_Ss I mean if you’re using incomplete systems, that Epic says aren’t ready for prime time, you don’t get to also complain it’s not documented lol.

[@As_Ss]

@@Clockwork0nions yes i do get to complain like a lot of other ppl, they need to provide documentation right now, how can u learn anything, even if incomplete if there is no doc, how long u want to wait? besides im not talking only this plugin, but overall lack of docs, samples, tutorials, nothing is chaos or async physics incomplete to you? they replaced whole physx and didn't even create in depth chaos docs u need to go and look for external tutorials of some ppl that somehow found out how to do more advanced things unity is embarrassing them with the amount of docs/samples/tutorials and advanced techniques available to devs u seem to know very little about the topic lol

[@joelkorpela2706]

It's literally all free and you're complaining, that's a crazy level of entitlement. Epic isn't obligated to do anything for you.

[@NextWorldVR]

Unwatchable. He says Ummm and Uhhh every third word. Learn some control over your words.

[@zeez7777]

I agree it can be improved but damn we're all humans, its certainly not unwatchable and i doubt you would appreciate the same level of scrutiny if you were to ever present something to alot of people yourself...

[@SneakyKittyGameDev]

I'm watching just fine, completely understanding whats being said

[@Bleeperish]

Just set the Playback Speed to 1.5

[@PolMarinMartin]

I agree that it's pretty much unwatchable. Some people like us can't stand the constant "ummm","uhhhh", it distracts us to a point were we litteraly can't watch the video. The same happened to me when trying to watch the latest Motion Matching talk (link: kzbin.info/www/bejne/qn_aap96Z7WKabc), the guy went "EEEEEEH" every 2 words, it was so frustrating I couldn't watch past the 4 minute mark. This said, you don't have to be that rude. Maybe instead of them learning "some control over their words", it's us who should learn to control our irritability and be more patient

[@Biru_to]

​@@PolMarinMartin haha, you ruined that video for me EEEEH 😂

[@alparlehelgergely1535]

uhm uhm uh uhm uh uh uhm

[@JackSparrow-xv7yk]

Focus on neural network which simulates game like doom not these minor updations see google deepmind recent research work upon that guys thats ready player one type of stuff fucking monopoly if made possible which inturn helps indie developer also

[@Biru_to]

Who cares about neural nonsense when your character doesn't move properly and networked physics aren't deterministic. Maybe you should go watch another video from the AI bros.

[@coldtech06]

Barely coherent

[@JackSparrow-xv7yk]

Im just warning these people to use its r&d coffers in right gamble Not every game has to be deterministic for eg human life is probabilistic there some undefined perfection in it

[@emrice6485]

Is this good for vehicle systems too? I am not that experianced but i will eventually need some vehicle coding so i might aswell start with this one.
