That feature is totally undocumented, so impossible to implement it without spending hundred of hours in the source code. No one seems to know how to use it properly while it would be really interesting.

I know this is a bit off topic but its still relevant to bring into the conversation. You are able to use Mover with characters and pawns right? But will it be able to process avoidance between characters or pawns like the CMC does in the future? Just asking this because Pawn avoidance still isnt a thing in UE5.

@@TheBlackGamerPT Epic are adding the AI support. you can checkout Github UE5-main repo to see latest updates. Technically this is not about mover. it's the pathfinding. once an AI has a path to follow, mover treats him just like a player but AI provides directional input based on his path.

@PenguinTD Ай бұрын

So, regarding the input also sent to the sim proxy, wouldn't that be necessary for you to do lag compensation? ie. say someone pressed jump on certain frame, server can play back the press and adjust for those, while clients gets the smooth interpolated result. BUT, for the cosmetic effects, like the jump puff particle effects, you would still need the input timing to arrive on sim proxy so you can play the particle effects but set the start time to whatever time is already past. (or for a ability casting montage where you can start play + starting offset and blend current animation to it if you know when the input started. ) If that's what are the remaining feature to target? would those filter need to be hard coded in? is there better way to decide which inputs to replicated but ignore the rest. (so ignore the stick/wsad movement, but keep jump/ultimate/dash for example. )

@SirKaizoku Ай бұрын

For player controlled simulated proxy with a kinemtic moving pawn , it is impossible to predict without bad visual pops and giving up on the 100% reliable world state. - Lag compensation refer to the server rewinding actor back in time where you as a local player saw them when you are targeting (for example shooting a gun). it requires a 100% reliable world state to get 100% reliable lag compensation. does not refer to making other player move forward in time in local player world. - you can control what gets sent to sim proxies and what doesn't, but this has to be manually coded in the NetSerialize function of the input /state struct. - it is not recommended at all to use 1 frame bools for now. example JustJumped bool that gets set to true on jump frame and false on next is not best to use with simulated proxies since they can miss an update and it can be the 1 frame with JustJumped is true. best to use states like IsJumping and check for the change in state between the sim output last frame and this frame. if IsJumping was false and now is true then it's first jump frame. - This is c++ only but there are things called NetCues in NPP that allow you to trigger events that get replicated. such as playing a sound , spawning VFX etc.. creating them is only possible in c++ for now but their purpuse is same as Cues in ability system.

Hey this is really cool thanks for sharing your work on this! I was actually looking at this exact thing a while ago for a game I'm working on and decided it would be more work than it's worth to finish it and went with a model instead where the server just streams state to clients and they basically just play it back like a video. This obviously adds input lag, which isn't a huge deal in my particular game but the plan was to switch to rollback in the future so thanks so much for this!

That looks awesome (and absolutely required) but I'm not quite sure yet about some things: - Why not offer it as a standalone plugin? Would be way easier to update. - This is a stupid one, but does this work for all movement or only with the default movement component? - What is exposed to BPs? - Any chance for continuous replays (deaths are sudden and unexpected) and on the same map (large-world problem)?

@SirKaizoku 4 ай бұрын

Hello, - it's not my plugin it's in the engine, i just did some updates to it. - you can create your own movement - almost everything can be done in BP for movement. except the structs that hold the state (EX: location ,rotation etc..) and input struct (EX:W,A,S,D , jump button etc). creating other simulation need c++. -Replay system in unreal does support different types of replay . including one that is suited for kill cams. they need c++ to setup and they are not directly connected to network prediction plugin . i just fixed a bug in it that prevented it from working with it.dev.epicgames.com/documentation/en-us/unreal-engine/using-the-replay-system-in-unreal-engine?application_version=5.3

@@amigoface i don't think an ability system made with NPP will use less network bandwidth if that's what you want to know. that is not its purpose. it would allow for many things GAS doesn't provide. fully predictive simulation(like over time effects etc..) easily works with mover out of the box.. but the bandwidth usage is easily controlled in NPP and might be possible to use less bandwidth than GAS with right optimizations.

@DarkSession6208 5 ай бұрын

What i don't get about Mover 2.0 is how Blueprinters are supposed to use it. I guess there will be zero documentation on release. Like someone said Epic should completely prioritize to get this working for both C++ Users and Blueprinters, but especially Blueprinters. Im 3 Weeks in into figuring out how to get Client Prediction on Blueprints when i have no joy in learning C++. I mean blueprinting itself is absolutely beautiful if it wasn't for networked movement. I tried everything except GMC. Smoothsync, SMN2, Boilerplating C++ code for sprint. Theres so many questions i have about this. 1) Will existing project be able to migrate to 5.4 because of this? I guess no because if you have a finished game everything will break 2) Will the Syntax stay the same, i guess there won't be the same "MaxWalkSpeed" function but a "MaxMoveSpeed" or something, which again breaks existing projects, so it will be probably only good for completely NEW projects that were not made in older versions. Which leads again to point 1 i have. 3) People using existing plugins won't also be able to migrate, and most plugins that involve even the smallest amount of CMC syntax will be legacy at this point, especially the good ones that don't get updated anymore 4) Is adding Lag Compensation and Client Prediction a manual process in BP? Or is it just Slap the Component on the Character and its done? Or do we actually need to add new network related functions before a event? Easiest example if we want to make a vaulting mechanic. Do we just do it as in CMC without Client Prediction and Smoothing and the Component handles the rest, or do we need to actively add nodes (example, dont know what they are called) like : "Net Predict Client" / "Wait for Server Response" etc, so in general does it add a lot more complexity like you need if networking currently in C++ or is it a fire and forget solution? 5) How are things such as linetraces/Animations handled? Because if i break a hit result the character will now have different components, so i guess older tutorials are obsolete. I mean its not that its a bad idea, its the biggest leap that epic did for me personally. But we needed this 5 years ago (at least for BPers). All that is important for me is Epic will actually provide a decent explanation. Not like they did with Lyra where they C++'d 80% and said figure out blueprinters...
