OpenWorldMovementLogic update for SaccFlight 1.6 has been released.

Basically an origin point shifting system tailored for SaccFlight. Player synchronization is also included.

This system basically allows you to go further the usual 40km x 40km limit when it comes to standard unity stuff before it starts going into a jittering mess. (Floating point errors)

Who knows, maybe you can make space travel with it as well.

Requires SaccFlight 1.6.
https://zzhako.booth.pm/items/3814760

[warped dune]

@pastel moon The way how player sync works is each player has their own attached stations.

Only the local player doesn't look like they have their own station; But everyone else is in a station, and is synchronized according to where they are at locally; And is synchronized accordingly based off their offset in the map position.

[pastel moon]

Thanks for the answer, I just saw the introduction in your booth, so withdrew the question

[warped dune]

Thanks~

Also, very interesting work you got there.

[quartz torrent]

I've been using UdonXML created by @west barn but found I was going to need to work with very large data sets for some of my upcoming projects that would halt VRChat if I tried to load them in one go. I've created a fork of the project and added an Async loading system now. https://github.com/Nidonocu/UdonXML
It includes a demo scene as well showing how to use it, I've published a live version here: https://vrchat.com/home/launch?worldId=wrld_d08332cb-09d6-4952-8081-ed9b8b90b32f
Let me know Foorack if you'd like me to do a pull request or some such to merge back to the main branch or such!

[coral sun]

thats pretty neat!

[coral sun]

I feel stuff like this may be useful for when we get world persistence / saves down the line, depending on the implementation we have to work with

[quartz torrent]

In my case, I'm going to be dealing with sets of questions and answers for trivia game shows that the VRC Gameshow communities do. Those are going to be prepared offline using a tool to create the formatted XML file, and then loaded in to the world by the quiz hosts before the show starts. :)

Previous solutions required updating the world every time, this means we won't have to any more!

[coral sun]

Sounds pretty convenient and a great way to maintain questions/answers long term!

how are they imported? is there like an ingame textbox that you paste into somewhere that this script then processes?

[quartz torrent]

Initial plan is a textbox to paste into. There's also ideas I'm investigating around encoding them in to image data in a video stream generated directly from the quiz database. But that's... a much deeper dive and something to look at down the line. But would be very cool if I can pull it off.

I've seen some other libraries by others though that show proof of concepts on how to do that.

[coral sun]

last one can be tricky. things like video compression could easily mess with things. Keep in mind VRC generally do not like video players used in this way (particularly in the sense of using them as "get" request mechanisms, which tbf you arent doing here)

remember that VRC does not allow editing of URLs within udon at runtime

you can can take a look later as this gets more polished, but tbh that may be more work than its worth

conversely, there are also limits to how fast you can transfer data between clients. An absolutely massive string like an xml with tons of questions and answers probably cannot be transferred in one go, and instead should be broken into chunks

its nothing insurmountable, but keep them in mind as you work on this

[quartz torrent]

The way this works is that only one person, the host of the show, loads the full dataset. Once the game starts, only the current question and answer data is selected and sync'd and displayed like normal. I was chatting with others and there's ways to make sure the video is 'clear' enough to not have ambiguous data, using checksums to validate as well. And yes. I think the idea would be, for safety, I'd point it at a locked URL for the quiz data and my quiz server would provide it an actual video that would be played and consumed by a video player. It just wouldn't be viewed by anyone and the hosting player's client would scan the video frames to turn it in to text, which in turn would be fed in to this.
That said, this would save like... one copy paste. Which given they are adding a Paste button soon. Well.... I might just keep it easy. XD

This would be one of those 'creative legal work arounds' that people love to make in Udon, but for all I know, VRC might suddenly surprise us with a websockets API of some kind and I would be both over joyed... and annoyed at all the work wasted. XD

[coral sun]

The current question/answer being synced only is so obvious its funny I didnt realize it lol. Yeah I think thats the best.
Ives been doing funky stuff with udon scanning textures/shaders, and while it is possible, it can be... funky

I think keeping this simple is the key, I wish you the best of luck!

[west barn]

Sure! Please do a PR if you want! Alternatively if you want to continue maintain your fork and I can simply link to yours.

[pastel moon]

Thanks, I will try to perfect it

[atomic crane]

Do you have to do the 3D portal effect using shaders?

[tidal orchid]

Messing around with some clocks that display the time in hexadecimal glowing in the colour the current time represents!~ always been fascinated with hex clocks

[pastel moon]

yes

[quartz torrent]

Sure thing, might tweak the text a bit more first on the Readme first then send one as I wrote it from a PoV of it being a separate module and I moved the folder in to a root folder rather than under your username. But that would break people upgrading so I'll pop it back in there. I'd rather it be merged in though as your repo has all the links to it! ^^
It also has the fixes for the bug report I sent in so that'll get taken care of too.

[blissful ocean]

may i ask, is this world public and if not are there any other world with decent drifting

[hazy trout]

You could try searching "drift" or "drifting" for worlds. For this one specifically a user named uoppoH has some public worlds.

Let me know what level of physics you're after and I could point out some worlds

[blissful ocean]

im pretty sure arcade, im just looking for something similar to Car-X

[hazy trout]

You could try this one. It allows rebinding, not sure if you can grab the steering wheel https://vrchat.com/home/world/wrld_56b44888-ca6f-40aa-95c3-7be9e8d6393f

[blissful ocean]

thanks, ill make sure to try it out when vrchat us working again

[hazy trout]

While we're on the topic of cars here is a later iteration of some sound processing for the cars. E.g. being more muffled behind buildings

[blissful ocean]

ok, thats cool

[celest burrow]

udon Noods 😮

[coral sun]

I wonder how the steam audio update will affect this, if it will do this effect for you already

Still cool that you did it by hand tho!

[hazy trout]

fingers crossed that will be performant. And if so I can probably remove the udon implementation I did for performance gains

[neat fern]

yeah XD
i have really bad humor

[ivory sorrel]

That's amazing 👏

Curious though, do your cars' sounds work off of pre-recorded audio, or is it synthesized? 🤔

[sinful hearth]

starting work on IL2UAsm, a better version of UdonSharp

[hazy trout]

Pre-recorded. I don't have much wiggle room for more CPU intensive stuff since udon runs much slower

[raven slate]

Does this mean I could code in C? Admittedly with probably slightly weird syntax?

[sinful hearth]

no, this is different than C

[raven slate]

I mean if you're using IL, can't you compile C to IL?

[grizzled nexus]

now this is epic

[midnight pike]

Is there a way to test it?

[dawn sky]

How is it different from https://github.com/Xytabich/Katsudon?

[lone gust]

yo, is there anything new with this? 👀

[copper cedar]

Have you an example with C code for unity? I mean the compiled dll, it would be interesting to see what operations are generated

[tacit prawn]

but do the cars actually have grip or is it like most that are drifty like?

[hazy trout]

I have chosen to go the simulation route. AKA I am using what is called a tire model that isn't Unity's godawful poorly implemented WheelCollider. The one I am using in particular is Pacejka 96', this sets the basis for having realistic enough tire physics so that one tire can do both grip and drift (if the car has enough speed or power).

[tacit prawn]

sick

[hazy trout]

Here is where a 1500 bhp car is used on the track. We can balance our input so that we minimize wheel spin

and another car where you can have more confidence with speeding through a corner due to downforce and a grippier tire compound

[sinful hearth]

👀

[tacit prawn]

i love formula 1 dude

I almost creamed my pants

[warped dune]

Any ummm... available git for this? (If it's available)

[sinful hearth]

not yet as it's still in early development

[sinful hearth]

only some of these methods can work 100% guaranteed. Like Name, Namespace, and FullName will work on any type you pass it, but IsInterface (for example) will only work on user types. For VRChat types, it returns false always

[proven totem]

https://vrchat.com/home/launch?worldId=wrld_a638f650-c82a-45e3-b119-17709b3ab1ac

[meager lodge]

I've not done any work on VRC content in a while! I've been busy working on a game built in unity honestly, I may come back to this at a later date 🙂

[raven slate]

Oh, no, that's not what I meant. I meant if using IL, I can compile C code into IL. I'm not referring to the normal Unity C plugin interface (though that is extremely convenient, not applicable). I would expect the syntax to be mangled, but I am just eagerly hoping that you make more progress on your IL port.

[copper cedar]

Sorry maybe i explained it wrong. I mean C code compiled to IL and packed into .net dll. I'm not very familiar with C and it would be interesting to see how it is commonly used in Unity.

[raven slate]

It's usually only used as a plugin, instead of as game code. Though, I have seen it marshaled the other way around. Do I misunderstanding what your project is? That you can take IL code generated with clang and go to Udon from it? If so what does that workflow look like?

[frank lily]

https://github.com/Xytabich/Katsudon

[copper cedar]

I am somewhat confused 😅
Yes, my project is converting IL to Udon. But not everything in IL can be converted. For example, it seems to me that C often uses so-called "unmanaged" approaches, such as pointers. They can be emulated in some way, but limited. For this reason i was trying to find out how C code would eventually compile to IL. I took Unity as an example, as it's interesting how exactly a plugin is created for this environment. It seemed to me that you are writing a similar code, and for this i was interested in you examples of such code, sorry for the trouble.

[coral sun]

This looks cool! Will certainly check it out!

[raven slate]

Hmm, I hadn't really thought about that. I was intending to write C using only handles and numbers, no pointers to make it compatible. But I don't know what landmines there could be where something I would do would implicitly create a pointer.

[violet karma]

Here's a tutorial on respawning a bunch of synced objects in your world, as well as an over-engineered chess set.
https://youtu.be/cAQWVq7o5x0

[smoky bay]

Lol, we both released a video on how to respawn an object
https://youtu.be/VTQgI5WwH6s

[violet karma]

Phenomenal

Literally would have had this up the same day as you if YouTube was faster at processing 4k lol

[smoky bay]

Lol, I feel YOU. it can be so slow sometimes, but then fast other XD

[violet karma]

OnTriggerEnter actually works perfectly fine if they're both triggers, you'll just need to have kinematic rigidbodies on anything you want to guarantee physics interactions with.

[smoky bay]

Really? Everyone online said otherwise... I'll have to double check then. This isn't a vrchat specific thing is it?

[violet karma]

I also recommend doing the GetComponent for the object sync then checking if it's not null, then respawning. That way you don't have to worry about managing naming correctly.
And nope, it works perfectly fine in Unity. OnCollisionEnter requires at least one non-trigger collider, while OnTriggerEnter can be between trigger and non or two triggers.

[smoky bay]

Hmm, you might have pointed out an oversite. What exactly do you mean about managing naming?

And yea, that probably where the confusing came from. I'll have to make a tweek to one of my upcoming videos...

[violet karma]

You're checking for "Item" to exist in an objects name, and while this works perfectly fine, it's something that you have to take into consideration and not accidentally change the name outside of that check. Again, your version works 100%, it just means other features need to be designed with that in mind.

[smoky bay]

Ah, there is an isValid check, but then I expanded the script to use the naming to specify if you instead only wanted it to respawn some objects, and not others (aka, the bush and not a pen). Figured using the name would be the easiest method for people to understand

[violet karma]

Ye no worries, definitely good to have ways to filter it.

[smoky bay]

Btw, thanks for looking over the video. Glad to have gotten a second opinion on it ^^

That looks amazing! Is an early version live yet?

[weary kelp]

nope, I only release worlds once they're 100% done instead of releasing wip ones

but there will be a demo out soon as part of an event

(keep any eye out for raindance immersive festival in october)

[slim peak]

oh cool, I'll give you a follow

Will do!

Could I ask where you get your materials from?

Or do you make them yourself?

[weary kelp]

a lot of them are by myself using substance painter

but the ones that are premade you can find on sites like artstation or substance share

artstation ones will be paid ones, depending on the license you pick

(the premade ones are used within substance though)

[slim peak]

Thank you! I've got 4 websites I go to for pbrs however I noticed for a lot of stuff you can't just put a single material on it to look good

[weary kelp]

oh yeah for sure, my environments are all atlased and textured in groups

substance is great at baking things and autogenerating stuff on edges + ao built on which is nice

[slim peak]

oh sweet

[weary kelp]

and then painting in normals using height map + masking

trimsheets also help a lot too so its useful to build those in aswell

and you can reuse those for different meshes

[slim peak]

Every time I think I know a lot I'm suddenly reminded how deep the iceberg goes lol

[weary kelp]

yeah I have so much to learn still too

an example of trim sheet object

built a bench out of one 😄

[slim peak]

Oh cool

Closest thing I've done is having 4 pixels, rgb and black for volume knobs to use the same material and have different colours but never anything with textures

[weary kelp]

its worth looking into, it'll open so many doors for you 🙂

[slim peak]

Thanks for the advice!

[violet karma]

Yo, here's an updated tutorial on how to handle syncing simple toggles inside of VRChat using Udon.
https://youtu.be/K3kAGQvrH9A

[smoky bay]

You used 'event, onDeserialization' in this video, but I honestly find using 'event, onVariableChanged' to be much more intuitive for graph. If you don't mind sharing, why did you opt for 'onDeserilization instead? Was it to simplify the udon# section?

Loved the video btw ^^

[violet karma]

One of the main things I try to do is keep the setup as similar as possible between Graph and U#. I graph the OnVariableChanged is pretty basic and easy to understand. But in U# the feature is much less obvious and takes quite a bit explaining, though the end result is about the same speed, it's much less intuitive and more difficult to explain. I actually went back and forth on which I'd use for this, and I might do a short video in the future where I show using OnVariableChanged as well.

[smoky bay]

So it was sharp after all.. Yea, the differences between the two can be pain. I shied away from doing both in my own videos for this very reason, but I definitely see the value in showing more udon# content, as it's definitely needed.
Thanks for sharing ^^

[dawn sky]

I made a Udon world which exports your avatar pose into a Unity animation YAML asset. The output is readily usable in Unity, and no conversion tool is needed.
https://vrchat.com/home/launch?worldId=wrld_f7999dd7-bd84-40df-bbe6-be822bfae2f7

[bitter atlas]

That's amazing

[coral sun]

I have been playing with this concept but never had the time to figure out the animation yaml. do you have the source code for this available? This is really cool!

[dawn sky]

Thank you. I've been trying to understand mecanim for more than a year.
The source code isn't available yet, but the animation YAML format can be easily learned from the output of my world. The difficulty doesn't lie in the format. The hard part is producing these numbers in the animation file using Udon, because VRC doesn't expose some low level mecanim APIs.

[vale fox]

Youve just had to rewrite that stuff?

F

[coral sun]

let us know when you manage to open source it. Yeah the animation yaml is "right there" but it seriously must have taken a ton of work to make a proper parser within udon. nice job

[smoky bay]

Glad you found this useful ^^
That being said, since releasing the video I found out that, due to a bug with object pools, the summoning script can cause the vrchat client to crash. There is a canny for it, so check it out for more details (https://feedback.vrchat.com/vrchat-udon-closed-alpha-bugs/p/vrcobjectpooltrytospawn-causes-client-crash-in-certain-uses)

As for how to get around it; as it's to do with becoming the owner of an empty object pool, you can simply replace the 'networking, set owner' node with a networked event. This will unfortunately make the spawning of the object a little laggy, and you won't be the owner of the spawned object:

Or alternatively, you could check the pool yourself to see if there are any objects that are inactive that can be spawned. A word of caution though, is that inactive objects != objects available to spawn. If you have a way of deactivating an object without returning it to the pool in your scene, this method won't work. If however you don't, then this method should work fine, and you would script it like so:

With all that said, if there is no way for the object pool to run out, then these checks won't be needed ^^

i do have a question for you on how to add an animation to the same trigger script. i have a screenshot in the questions section if your willing to assist.

Love your videos thanks for all the work 🙂

[hazy trout]

Soft body tires for ISO 8855:2011

[coral sun]

Random ballpark guess, but is this using some sort of depth camera and a custom vertex shader?

[hazy trout]

I have not even considered writing a shader for it. There is only physics calculation for it at the moment

just think of it as a spring for that calculation

The cleanest most relevant diagram I can find is for motorcycle dynamics where they have to calculate the cambered tire when the rider turns a corner. My application is to have the tire pressure affect the ride quality and handling

[glossy ice]

i want to make a personalized roulette , someone have one?

[rotund maple]

I love that you're looking to technical papers for inspiration and guidance.

[vale fox]

Technical papers are the source we can steal learn from

They did all the math for us, may as well use it!

[hazy trout]

Kinda have to if I don't want to spend years or months coming up with my own formulas just to be able to have measurements up to ISO/SAE standards

[hazy trout]

also been working on different drivetrain setups such as all wheel drive, and implementing ways to fine tune more of the sounds I put onto the cars

[vale fox]

[coral sun]

you are putting more effort into a vrchat asset than some indie teams put into their entire racing / driving simulator games. respect

[vale fox]

Can someone who knows blender really well, help me with something later today?

I need to make this into a 3d mesh

[timber lily]

Now implement midi so we can actually use our driving wheels and pedals to drive it

[rich mountain]

can anyone who knows how to use blender well help me with something

im trying to get a specific curve but cant get it right

trying to get this curve on the 2 beams

[hazy trout]

Any tips and metrics? Like rate of messages

More than 12 hz would be nice which is what I estimated for OSC when it comes out for worlds

Ideally more than 30hz

Also pay me

[timber lily]

I was working on steering wheel app that would convert the analog inputs to midi so it could be used in vrchat because i wanted to make something like you're doing but yours seems way better so i might give you the app instead for you to implement it

[hazy trout]

I would see a generic udon class being the outcome for this, and anyone who wishes to use it will have to write an adapter for their udon car system

[hazy trout]

I see that you haven't tried asking #3d-modeling, I looked in there and saw that they do use Blender. This channel is for showing Udon creations

[hard axle]

Do you like revolver?

[tall terrace]

playerPool.GetObjectByOwner(Networking.LocalPlayer).gameObject.transform.Find("PhoenixPlayerManager").GetComponent<PH_PlayerManager>().SetProgramVariable("teamID", id);

https://tenor.com/view/kill-myself-seatbelt-gif-13298646

please show me your udon gore, im sure theres worse

[hard axle]

That's a very special way to mark player a teamID, have you thought about keeping the references so we don't have to access other scripts with Find functions?

[tall terrace]

I keep references where I can, but some things need to lookup your local player's assigned controller at some point. I could get rid of Find by just having my controller script on the same object ig. If we had static variable support I could make a dummy singleton object that at the very start cached your local controller and always go through that to grab the reference.

For everything thats getting your local controller I'm sure I could store it at the very top in like the gamemode manager and always pass it down, or instead of making a static singleton literally manually reference an object that stored a local reference every time I make a new random piece of game logic. but usually using this functionality to find someone else's assigned controller.

Mostly its just because I try to avoid having rpcs and operating on all the information each player has locally to deterministically come to the same result, but a lot of that requires up to date knowledge of which controller is assigned to who. Incase people leave or rejoin and controllers get swapped around from the pool.

[hard axle]

I just keep a reference when I assign the character binding to the player, so I can reference and checking this player's character data just by accessing to this localCharacter variable. And unbind the character from the player if they leave. But I'm not sure how you structured your player pool network system. This may not fit in your case.

[tall terrace]

yeah I could cache the local player, but if a trigger needs to lookup the assigned player controller based on just the vrchat player that walked into it still need to lookup which one that player owns right? Unless theres a better way to handle individual player data.

[coral sun]

now put this in Update()

Have you seeen that horror game. in silence- where the predator is blind but can hear the other players?

havent seen it done in vrc yet, but that thing you got there would be so cool if you or someone wanted to make a vrc game like that

[bitter atlas]

Yeah, the little mockup above was inspired by dark echo which is that exact thing lksdfj

I'm not good enough at horror or level design to fully get something like that done though

Last time I tried making a horror map it got pretty popular and then people ended up threatening me over it being a tech demo more than anything (which it was). Not going to make that mistake twice

[vale fox]

People getting angry at maps confuses me so much

[pallid smelt]

It's the same kinds of people that get angry in youtube comments over someone not being 100% historically correct about something irrelevant (bonus, those comments are usually wrong)

armchair devs, armchair engineers, etc

wheeeee

[vale fox]

Some people have way too much free time ig

[pallid smelt]

Am curious though. Screen-space on the depth buffer, or world-space as a material shader?
And if material shader, I'm curious how you're transmitting across surfaces. (I'm still new-ish to shaders so there are probably features I don't know, though I know enough to make a very basic raymarcher so consider that my level of knowledge)

... oh wait.
is it a sphere expanding out with distance to surface stuff (whether virtual via shader math or an actual sphere idk) and using that distance to actually shade the pixel?
No I'm seeing reflections, that doesn't make sense... h m

I'm curious how you did it.

[bitter atlas]

world space, made with quest in mind ^^'

[pallid smelt]

How are you feeding the pings into the shader? I assume it's a separate object, so I'm guessing global tex with some stuff reinterpreted as floats for pos, or something else?

(I only know a small handful of techniques :P)

[bitter atlas]

just 2 little arrays, one float for time and one vector for positions. always overwrites oldest one if amount exceeds

it's super lazy but hey it works

[pallid smelt]

Ay, if it works, it works~

[bitter atlas]

the low framerate is my pc, not the world ^^'

quest compatible funny paint shenanigans

[bitter atlas]

this is what motivated me to write my own system for this skjdf

[stable phoenix]

how's the performance for it on Quest

[bitter atlas]

Right now a stable 70+ fps, can't say if it'll be the same with many projectiles at once ^^' shouldn't be bad though

[tribal egret]

that's great, how well does it work with different uv mapping? For me it was kinda weird on more complex models because it used a distance function in uv space, which looks weird on models that have uv unwrapping that's a bit streched/doesn't have the different uv faces next to eachother

how did you do it btw? I did some weird workaround where it got the contact point from a collision and then used the inverted normal vector to cast a raycast to get uv space coordinates

[bitter atlas]

I just used a seperate camera that renders the mesh using a distance function (in world space!) to the UV coordinates on-screen, then blit that to a seperate render texture

And just update the camera each time something needs to be added

There's some very subtle gaps inbetween UV islands that don't touch but it's not too noticable if you don't pay attention to it

[tribal egret]

oh interesting, would you mind sharing the code?

[dawn oxide]

that's nuts. Can't wait to see what you make with it

[hazy trout]

I have some PVE stuff in mind after I do a big chunk of work for my udon car physics

[valid shoal]

If you make some kinda coop tank crew simulator, that would be hella fun with some friends!

[hazy trout]

Yeah, there is one blocker. VRChat's interaction system and my own implemented system has the same issue in-game, where even using LateUpdate or PostLateUpdate would still have us observe the interaction flickering in and out while the vehicle is moving.
A possible workaround is to keep the player static and move the world, however, that has performance drawbacks such as not having static batching.

[dawn oxide]

I got to use a system like that like a week ago (stationary vehicle movement logic) and it was very cool, but the performance impact was high as you said.

[long mauve]

could instead move a camera located elsewhere in the world, and display it through the tank's periscopes? o:

[hallow pumice]

That works for having a flat texture, but you don't get any parallax/VR effect with it. Depends on how far you want to take it.

[solid elbow]

since the user would be stuck inside a vehicle, what you could do is just like a periscope and not expose the user to the outside world and it can just be the tank's POV, but not be the actual tank so the user is somewhere else

[smoky bay]

you could also just activate a camera that doesn't have a target render texture on it to temporarily change a player's perspective to that camera. Then would then just need to put a shield around the camera to limit their view, and just that should be enough to sell the effect

[coral sun]

this wont end well in vr

[hazy trout]

Hi all, part of a great tank experience is to be able to "turn out" and in. Where the person would open the top hatch to expose their head and survey the area without the confines of the interior. Therefore, I will be implementing a control scheme suitable for this experience that does not require the local player to be in a stationary interior of the vehicle.

Periscopes are 100% possible, I will post a video demonstrating a camera that moves independently of the turret that shows the gunner's aiming

[hazy trout]

This setup applies to a modern fighting vehicle.

1. Camera that moves independently of the turret.
2. The main gun that tries to match the elevation towards the camera's view, and is restricted by it's rotation speed.
3. Gunner's view of that camera
4. Turret base that tries to match the elevation towards the camera's view, and is restricted by it's rotation speed.

For older tanks such as WW2, you would have the camera move with the turret instead.

[hazy trout]

A concept that I made a year ago, I'll get back to this once I do a bunch of car stuff.

[coral sun]

Damn, nice

[novel oar]

Just as a quick note on this - I've had success with making a 3D camera... using two cameras for left and right eyes, and rendering them to a material using a shader that can display one render texture to the left eye, and the other one to the right. So long as you're a fixed distance from the "screen", the effect works well. XD

[hallow pumice]

Very cool! That's an effect I'm also interested in. Is that a custom shader you made? Any unexpected challenges/wrinkles?

[novel oar]

Oh, there was a video player prefab that had a 3D movie toggle. It switched to a shader that could take over-under movies and play them in proper 3D. I just repurposed that, but I can't think for the life of me where it came from now!
If you know anyone who does shader stuff though, it shouldn't be too difficult to make one with two texture inputs and just send them to different eyes~ ¦3

The only challenges was really just trying to figure out the distance apart the cameras should be. That depends on where the viewer would normally be sitting... when you're closer to the screen, the 3D effect is flattened. Further away, and it's exaggerated. So it's just a case of deciding where the moajority of people will be viewing from, and then tweaking the space between the cameras to give a decent 3D effect.

[bitter atlas]

multiple points on a rigidbody that when below the water surface just add upwards velocity

having the center of mass be below those points make sure the ducky is always up straight

[bright locust]

Not udon, but I made a tiny script that sends dad jokes to your chatbox.
https://github.com/JonShard/JokerOSC

[dawn oxide]

VRCObjectSync (red) vs UdonSynced (blue)

[frigid bronze]

Nice! Are you just sending any changed transform values to UdonSynced variables each frame?

[dawn oxide]

it's a little bit smarter, there is a threshold value for position and rotation and it only sending data when the cube has moved/rotated

there are 3 UdonSynced variables (Vector3, Quaternion, isKinematic) and a tickRate so it's only sending 33 time per second and only if the object has moved.

[boreal nest]

that looks really good! Do you have any way to sync it up with the player while they are moving? It looks like you might have lower latency than the player so it would drift ahead of them

also, vrchat network sync only comes around 10 times per second, so even if you requestserialization more often it won't do any faster than 10

[dawn oxide]

yes the cube sync faster than the player but idk how I could fix that. it's good to know for the limit.

[boreal nest]

there's a few ways to handle it. VRC objectsync handles it by having a "simtime" that all synced objects have which represents how far back in time you are seeing that object, and when holding a pickup it will use the player's simtime.

I have some udon synced objects and I handle the problem by syncing an integer which indicates which bone it's attached to, then the position and rotation are just in local space relative to that bone. though it significantly increases the complexity of the interpolation math because you need to smoothly transfer between different spaces

another solution I've heard somebody do is have a synced object for each player, and then while holding something, it just subtracts the difference between the player and their object

[dawn oxide]

that's a very nice idea ! so you don't even need a VRCObjectSync at all, all we need is just attach the object to the hand

but that wouldn't work for other moving objects that are independent

[frigid bronze]

So how's the smooth motion happening? you using lerp like phasedragon mentioned?

[boreal nest]

well, if it's not attached to a player's hand then it just syncs normally

[dawn oxide]

t.SetPositionAndRotation(Vector3.Lerp(t.position, position, Time.deltaTime * lerpRate), Quaternion.Lerp(t.rotation, rotation, Time.deltaTime * lerpRate));

[frigid bronze]

niiice im taking some notes hahaha

[dawn oxide]

but with many objects, it becomes very laggy, much more than vrcobjectsync ;/

[boreal nest]

yeah, manual sync is not very consistent in when it arrives. You'll receive bunches of data all at once and then nothing for a while

that's one of the advantages of continuous sync - it spreads those out over time. That's why even without interpolation, it has added latency

To solve that in manual sync, I had to build a circular buffer of positions/rotations and then "replay" the data as it arrives. The most difficult secret sauce part of that is figuring out how far back in time you should replay the data. If you go too far, it'll have too much latency. If you go too close, it'll freeze when it runs out of buffer

[dawn oxide]

hmm I see, is it possible to increase the amount of data that can be sent with UdonSynced as a possible solution?

[boreal nest]

sure! You could send an array of positions/rotations instead

you could sample positions at whatever high rate you want and then send it at the lower udonsync rate

[dawn oxide]

hmm, I am currently working on a pinball, and I would like the ball to do exactly the same for each clients. I am thinking if I can just sync the initial velocity of the ball and hope that the physic on each client will do the same thing with just 1 information ?

VRCobjectsync is really too slow for a pinball

[boreal nest]

ah, yeah, extrapolation is another approach. You can definitely do that, but the problem is if it changes in-flight, you need to smoothly correct it back to the source

you can do extrapolation either with physics or with raw math

the planes in test pilots use extrapolation because formation flying wing to wing is very important

https://twitter.com/Sacchan_VRC/status/1577045550293082112

Sacchan (@Sacchan_VRC)

Here's what my test setup for netcode stuff looks like, the red plane is the 'raw' data with some best guess extrapolation, the green plane is the smoothed plane that other people would see. I want to see if I can get the green plane to stick a bit closer in a sustained turn.

[dawn oxide]

they are actually pretty close

considering the speed

[boreal nest]

if you're doing pinball, then I think fidelity matters more than latency. If that's the case, sending a packet of positions that were sampled from a higher update rate is the way to go

[dawn oxide]

ok ill take note, thank you for all your advises, its much appreciated

So that OpenAI ChatGPT knows about vrchat, it also knows about udon and can also code in udon. So have fun

BUT beware it can also be very confidently wrong like this example.

So try it out and test the code.

[coral sun]

wouldnt this not work as well?

it would just rotate to whatever your time is currently

[coral sun]

this assumes your skybox has some sort of mesh, which generally most people do not do this

[hasty oar]

@coral sun The first two code should work its the last one that should not as you can not scale the player like that but the AI was confident it would work because it assumed it would it can be very confident wrong. Btw I showed this to a friend and he said that the skybox rotate code is nearly identical to one he already has. This chatGPT does not have that code stored in its data base it used what it knew of vrchat udon to make it from the request I typed thats whats so spiecal about this. It can make you code it does not know by figuring it out.

I've been trying to find an inventory solution for a while. It's cool that they're a thing now. I'd made a similar system to hold one object and was struggling with getting the sync right. Glad i found something better lol. All we need now is item stacking and we'll have udoncraft!

[vague coral]

[bitter atlas]

[wicked rivet]

What shader are you using to make the ocean waves in the background?

[bitter atlas]

unlit :)

It's just a subdivided plane that has its vertexes displaced and centered on the camera's X and Z, has normal displacement with more iterations in the fragment shader (using DDX and DDY to make it run very fast on quest), and samples the skybox (as in using the same function the skybox uses)

[wicked rivet]

Again with the vertex displacement thing. I can't find a VRChat compatible shader anywhere that does waves like that, I tried making one myself but I didn't really know what I was doing and it came out super jank lol

[bitter atlas]

I'm pretty sure I based it off of https://www.shadertoy.com/view/Wl2Gzc

The actual vertex displacement is just so it gives it more depth for stereo purposes, it's only general shape not the smaller ridges

like, the vertex only has like 3-4 iterations compared to the fragment's 10-12 or so

this is also to get away with a very low poly plane ^^'

[dawn oxide]

i know poiyomi supports vertex displacement with a heightmap that supports scrolling @wicked rivet

there's also this https://booth.pm/ja/items/1224312

i think s-ilent also has shaders for water and general purpose ones with scrolling vertex displacement

[wicked rivet]

Oooh this is awesome! Thanks! :)

Where do I go to get to the ducky's

[bitter atlas]

https://sketchfab.com/3d-models/rubber-duck-f1de4fc390db4266a509b9739350512a

development has been cancelled, for some reason generating 1d perlin noise in udon is super intensive (which I used for the 'bobbing' physics)

but thats the base ducky model - same one used in placid plastic duck simulator too

[covert flame]

ty so much am gonne keep the ducky's

[gaunt night]

Generate it in a shader and then use Graphics.Blit ;)

[ancient briar]

https://www.youtube.com/watch?v=v4aidrut2mU
In the middle of making a live preview teleporter you can walk through and doesnt feel like you teleport. Udon is pretty cool

[bitter atlas]

Wouldn't looking up rgb values from a texture be more intensive ?

[coral sun]

Does this work in vr? Thats where the coding becomes super fun

[gaunt night]

not sure, would have to test it out

[ancient briar]

I have not tried in vr yet. Is there an issue where render textures don't work with vr?

[gaunt night]

Yes plenty.

[bitter atlas]

Because I remember that specifically being very slow on mobile devices based on the engine I used to work in)

Thats all

[coral sun]

Vr is 2 cameras, you need to do both

Also you can do more complex rotations

[ancient briar]

Im aware of rotations being an issue

[coral sun]

So the math becomes more triky

Its possible, I know of someone who did it

[ancient briar]

But more concerned about rendertextures being an issue

[coral sun]

Getting ipd is also a pain

Render textures work in vr? I have used them

Well, it depends what you mean

[bitter atlas]

I recommend looking at the mirror.shader shader if you need to basically display a texture seperately on each eye

[coral sun]

They work, but not necessarily how you'd expect in certain use cases

[ancient briar]

sorry multitasking at work. 1 sec

[ancient briar]

by ipd do you mean the aspect ratio of the players camera? Got that sorted probably. Found a way around vrc not allowing ScalableBufferManager

[ancient briar]

I will have to look into this

[coral sun]

From what I heard from my discussions you'd have to get the camera scale in the world

Not sure if there better ways cause thats super jank lol

And by IPD i mean the distance between the eyes

Thats not constant

Its been a while lol, its fuzzy in my head now

[ancient briar]

Yeah that might be a rabbit hole I have to go down yet. Im guessing issues with perspective per eye would have to be something sorted at the shader level, but Im still very much a novice in that sort of thing

[coral sun]

I haven't worked on it myself, but I know some people who have. Pattern is basically "making the desktop portal is easy, but the vr one becomes a pita"

Pretty much they all gave up and dissected a paid unitypackage from booth or one person did make something but took certain shortcuts leaving it super unoptimized

Brush up on 3d vector math is my biggest general hint I can give lol

[ancient briar]

Ive already had to figure out some angle stuff to determine the near clipping plane of the follower camera. Quartinions are evil

else you would see what is between the other portal and the camera... say a wall

[coral sun]

If you are doing math with simple angles, you can probably get away with it in desktop mode, but doing this in VR will be next to impossible

[ancient briar]

Im using vector maths

[coral sun]

Well thats good

[bitter atlas]

Well, the main issue is finding out the eye distance or exact eye position to place the camera, and repeating/seperating it for each eye. Everything else can more or less be converted directly

As far as I recall when I tried this myself at least

[ancient briar]

Im guessing the placement of the camera at the head of the player puts it somewhere between the eyes... or the center of the head bone?

[coral sun]

Head bone varies per model

Use the tracked

[ancient briar]

sorry thats the one Im using

[bitter atlas]

There's no way to track eye position at all using udon if I recall correctly, which is what makes this so hard

There's no single number either as eye distances and positions are variable per avatar

Only inside of shader code, where you can enable stereo rendering and just use the world space camera position

[ancient briar]

thats weird... I would expect the shader to know where its drawing to

[bitter atlas]

Yeah it's just not exposed to udon I believe

I could very much be wrong about this but this is where I personally hit a brick wall

[ancient briar]

Thank you very much for the info. I feel like Ive fallen into a trap. At the very least you've saved me time hitting my head against a wall knowing that there is probably not a solution

[slow dove]

Why not like handle it all on the GPU? How expensive would that be to just use two depth cameras for collisions on Quest?

[bitter atlas]

I have no idea what you mean with this but depth textures aren't supported on quest iirc

[slow dove]

It totally is

I've used it for my texture painting world to have brush occlusion

[bitter atlas]

I guess it's just not for the main player's camera then ?

Weird

[slow dove]

You talking about the _CameraDepthTexture?

[bitter atlas]

But what do you mean with using depth cameras for collision kjsdf

And yeah

[slow dove]

Turning the pool into a cell-based system where each duck is simulated as a particle, and using 2 RTs set to be depth to determine if something's in the way of the duck or not

Similarly how to Cnlohr's or D4rk's ballpits work

[bitter atlas]

That would be neat if that worked with the world's concept

And also enjoy syncing that skdfj

Appreciate the ideas though 👍

[slow dove]

Oh yeah, big pain xxxx

[coral sun]

It is possible to get the eye position

Its just a pita

From what I understand its not even a vrc issue, but rather a unity/steamvr thing

If I had more details I'd put in a canny myself to have a nice method to get the info directly lol

[hallow pumice]

Closest intended way you can get to eye position is the headset position
#udon-general message

Note that eye position will be slightly off from headset position as in VR you have two eyes that are slightly offset left and right.

And the offset will vary depending on avatar size.

IIRC if you must have eye position there's some hacky ways you can get it. I can point you at them but I don't understand them myself.

i was going to adda screen freeze as well like the black mesa transport system avatar, but friend said its not a good idea cause motion sickness, I did however fix the position of the "node graph"

[coral sun]

I mean you even added the old water splashing bug

[ocean saffron]

cause one of my friends was like "ooUGH NoDe GrAPH is Not In ThE rIghtSSpot"

[ocean saffron]

thats a bug, i thought thats just a thing when you load in xd

so i added it

i also added cars

[coral sun]

its technically a bug in source

[ocean saffron]

ah fair enough

i also got the lightmaps looking proper now

had to do some linear to gamma conversion

and i baked all the static props

[coral sun]

are things like welding and ropes network synced?

[ocean saffron]

...

i never added those

[coral sun]

I mean I would impressed if you found out how

ah

[ocean saffron]

nor will i

idk how

also the world struggles as it is

with only the prop system

i have a weird issue

[coral sun]

tbh. stuff like that would be a pain until they finally support syncing methods with inputs over the udon network

[ocean saffron]

i cant show u rn cause im banned

but past testing showed the following

so i join in vr and im getting like 60fps for like the first 5 mins

i do ABsollutley nothing and then they start climbing down

eventually i am at 30fps

then its starts

[coral sun]

in your map?

[ocean saffron]

30fps for 5 seconds, then 10fps for a split second

over and over again

yes in my vrchat world

i have no idea what is causing it

[coral sun]

I would check logs to see whats going on

[ocean saffron]

its never happned in the editor

the logs show nothing

ive checked

ive used the profiler, ive used the frame debugger

but nothing shows anything bad

[coral sun]

well, if its your map specifically that does it, then something is responsible there. Most likely some script. Does ram / vram usage increase till it hits some point?

[ocean saffron]

i never checked since i cant use task manager in vr

cause fucking elevation

but i used the timing info

and there were spikes

when i got the werid lagspike pattern

i have 7 udon cars always active, if they are just sitting there they shouldent lag

and it would lag as soon as you join so idk how it could be the cars

if it happens like 5 mins in

[coral sun]

I imagine some script continuously allocating something

[ocean saffron]

could you vc and i can show you the editor, maybe you can spot something i cant

[coral sun]

cant rn, but honestly I would remove segments and see what causes the issue that way

[ocean saffron]

i cant really test tho since im banned, and it doesnt happen in the editor via clientsim for some reason

it only happens in game

idk if its only vr cause i rarely use desktop anymore

[coral sun]

some networking calls work differently in client sim vs in game, but its only a guess

[ocean saffron]

i tried to debug this in the past via unityexplorer

but look where that got me

XD

[coral sun]

F

[ocean saffron]

should i enable deep profiling in the profiler

it says it will reload all script but i think it will show me what is happening

[ocean saffron]

That’s nothing

[hot dove]

i built a game boy emulator in udonsharp, but WOW it is slow

[hot dove]

are there any basic tips on getting Udon's VM to run faster?

[boreal nest]

yes, the main thing is try to use functions that move the work outside of udon. It very much depends on the work you're trying to do, but even if it's a roundabout method that needs multiple different functions to go in one direction and then come back, it can be more efficient than just doing raw for loops or while loops.

[dawn oxide]

my code is a mess all it does is open and close a book and sets varibles

[dawn oxide]

thats awesome

[hot dove]

it's all mostly math, moving bytes around and such

[dawn oxide]

how many lines is it if it is one script

[hot dove]

it's eight scripts, about 3,000 lines

[dawn oxide]

damn

[boreal nest]

here's an example: outside udon, it's pretty quick to just do something like this, just raw loops that get it done asap without any allocating private static void SkipToCharacter(string source, ref int index, char character) { while (index < source.Length) { if (source[index] != character) index++; else return; } }

but in udon, it's faster to make use of built-in functions. In this example, these functions allocate new strings which can be relatively expensive, but because it avoids loops inside udon, it ends up being faster. private static void SkipToCharacter(string source, ref int index, char character) { if (index >= source.Length) return; if (source[index] == character) return; int originalLength = source.Length; source = source.Remove(0, index); int newIndex = source.IndexOf(character); index = newIndex + originalLength - source.Length; }

[hot dove]

Huh, okay, that makes a lot of sense

I'll see what I can apply to my code - thanks!

[dawn oxide]

i made a peer to peer remote access program for windows in c# only about 1000 lines before

simple north pointing compass

[simple berry]

This looks cool. Do you know if it has the same issue that other teleports have where avatars of other users briefly go sideways before teleporting if going long distances?

[glad barn]

ive not tried with long distances, but it shouldnt matter with it, as the rotation position and momentum is conserved so you shouldnt notice that weird sideways movement

i think that movement is actually caused from the conserved momentum but not your rotation

which is why it seems weird

[simple berry]

Interesting. I'll see about picking it up. After seeing this, I want to see if I could recreate some of the mechanics from one of my favorite games, Antichamber

[glad barn]

that wouldt be greatly appreciated, if you find any issues with it ping me a message and ill see what broke xd, but i look forward to seeing what you could come up with!

[hazy trout]

Updated my sound controller to conform to the new forced induction simulation.
The sound of forced induction has two major components.

1. The rush of air from the forced induction system (this may not be heard if you are far away from the components)
2. The system's turbine, usually high pitched and can be heard over longer distances
   Optionally, there is a way to bleed excess pressure from the system and this can be heard after decreasing the throttle

[lilac obsidian]

Wow, that's awesome. I would love to know how you did this. I"m trying to figure out how to get stereo sound into my world from a github playlist, and I can't figure out a way to do it. I could do it in another platform that shall remain nameless, but not in VRChat. I can't get sound of SoundCloud into my worlds either even though it should be possible.

Thanks! Several of the Unity audio components are exposed to Udon. I get the player's hand position on x, make the slider follow the hand within a set range, and then remap that range to whatever the audio component uses (so between 0 and 1 for volume). For your github playlist, maybe you will be able to use the new feature in the latest developer update, getting string variables from an online source 🤔 though I only skimmed over it

[icy sluice]

this might be a dumb question but how does this differ from just calling teleport on a player

[glad barn]

so when you teleport a player to a transform its setting the player position and rotation to that transform, so for the cases where you don't want to make it obvious that your teleporting a player, for example between two identical elevators in different rooms you will notice straight away that you've been teleported as you most likely are not standing in the exact position and orientation as the teleport position. with this script it calculates the offset from that position and applies it, so the player will teleport to the exact position and rotation of where they were in the previous elevator in the new one, all assuming that the positions and scripts were setup correctly to start with. hope this helps

[gaunt night]

Im not sure if you did, so Im gonna ask:
Did you make sure to also correct the velocity when the two targets have different orientations(rotations)?

[glad barn]

not implicitly yet, but ill have to test that out, but im not sure it will matter as the exit transform would be orientated the same as the enterance in local space to their own rooms, i can draw something rq that might make this make sense xd

is this what you mean, the player moving throught the red room teleporting to the blue room which is at a different orientation in world space to the red room?

the blue arrow is the z(forward) direction of that respective room

[gaunt night]

I dont think you fully understood what the problem is. Here is a demonstration:
The red and blue surfaces are the relative targets, with the arrows indicating their normals/orientation.

On the left we have the initial player position and their current/initial velocity.
When teleported the velocity needs to be adjusted, since the velocity is in world space, not in object space.

The velocity essentially needs to be "rotated" around the Cross product of the target normals/forwards by the angle between them.

This is a classical problem when attempting to make portals, which I ran into as well when I tried it.
And its easy to overlook. It depends on the desired effect you want to have, but generally its better to correct the velocity, instead of leaving it as is.

[glad barn]

yeah i understand what you mean, just got a clip of trying it out with your setup above and i didnt find any issues strangly, but its something ill keep in mind i just might be doing it already accidently xd

[gaunt night]

In the clip you show the initial and end orientation are the same, so the problem doesnt show.

[glad barn]

did i just prove your point correct xd

[gaunt night]

Probably

[glad barn]

the blue corridor is 180 degrees rotated of the red

[gaunt night]

If it was meant to turn you around then yes.

[glad barn]

omg now watching it back, your totally right

i even setup the 1/2 balls to help notice that

[gaunt night]

As I said: Its easy to overlook 😛

[glad barn]

it feels correct and clean

you totally dont notice it xd

yet if there was a wall in the way you definatly would

[gaunt night]

Intuition is a bad measure for correctness.

[glad barn]

yeah honestly is, sometimes it gets the better of you

[slow dove]

Not anything a little quaternion math cant solve :3

[glad barn]

a hah, actually the setup was wrong for the example xd, but the issue is still there anyways lmao

will work on a fix for that shortly

[gaunt night]

Yeah this one should actually be quite simple (A * Quaternion.Inverse(B)) * initialVelocity if Im not mistaken

[glad barn]

has been litterally the only thing ive been working on for the last few days, i feel im turning into one tbh xd

[glad barn]

yeah looks like what i was about to do

[lilac obsidian]

Where would I find this resource. I'm very new to the platform and I'm not a coder, so I'm pretty reliant on prefabs. I tried a audio player kit where you can put links, but it didn't work. I got tons of compiler errors, and had to delete it.

[grim stag]

I don't know where to post this but I apparently sleep texted in discord and of course it was about unity lol. who else has dreamt/had nightmares in unity before? 😹

[slim peak]

Basic Udon but satisfying to see it working well

[dawn oxide]

Phat

[teal cypress]

What I like the most there is how the shades fold nicely.
The ones I have at home are a mess xD (not pretty and waving like they haha)

[slim peak]

I wish I could say I did more than just squish them xd

[teal cypress]

Hahaha was it really that simple!

damn, I thought it was super complex and not just scaling

[slim peak]

yeah, used a blend shape but could've easily done it in unity by using the scale

Would've got the same effect

[tight inlet]

https://fxtwitter.com/SLKinix/status/1618383213826564096 I guess I cant really put just a clip of udon and all the technical stuff, but I updated this world with a TON of things from the latest update of U# (1.2.1?) and my god, do I love the inheritance of classes being used to the maximum for this world. Cannot wait for Lists and other goodies to upgrade my game :>

[vital zephyr]

Working on a quick security module to get acquainted with networking in Udon#. The system uses role-based user access levels (can tp user to location on role set and de/activates objects based on user's access level, ex: enable specific doors for VIP), automatically updates display as users join/leave, contains view filters (per set role), and a robust command structure (tp to/from user, activate fly, remote call with video and audio, etc). System has been optimized for multiple instances/any number of objects can exist in-scene with different forms (stationary control desk to mobile tablet). The standard system object is networked using the current operator as the scene authority, but the object can be broken down to a purely local object (each scene admin can summon their local object and use it to send networked commands). Starting to round off and polish the code, but do you guys thing I missed any possible features?

[zenith imp]

Uuugghhaaaa....

[stable phoenix]

at that point you might want to be writing in udon Sharp?

[coral sun]

so has your udongraph achieved self awareness yet?

[zenith imp]

That would make sense if I could read code blocks.

But I have no idea how text code translates into stuff code.

[zenith imp]

Soon. The npcs are aware of some things.

[spark arch]

It wouldn't be that hard. There is even a server called 'UdonVR'. That helps with coding.

[zenith imp]

I would literally would need hand holding and someone to sit down with me until it clicks and writing in text and seeing the flow of data becomes easier than seeing on a node graph. I've never taken a computer class.

[coral sun]

its best to start slowly with simple projects. there are quite a few udon sharp tutorials on youtube. Eventually you will start getting the hang of it.

Node graph is cool for making small things, but once you reach a certain point it becomes infeasible for large projects

[zenith imp]

People tell me this yet I'm making a complex networked synced NPC AI system.

[teal cypress]

Using node graphs is a perfectly acceptable way of coding

In some cases, it is actually a lot easier to understand node graphs than lines of code.

@zenith imp keep up the hard work! I am looking forward to see how it turns out!

[teal cypress]

Does Udon support making custom nodes?
It would be really cool to write some U# to be reused on node graphs

[coral sun]

in udonsharp you can make custom functions and all just like c#. From what I understand, udongraph (the node based method) does not, but I may be wrong here

I believe you can create custom events but they aren't "nodes"

pretty sure they were on the unofficial roadmap tho

[teal cypress]

Gotcha

We will get there 🙌

[coral sun]

from what I saw in examples, custom methods could be defined that you can call within the graph elsewhere, but they weren't custom nodes you could copy and paste

[zenith imp]

You can copy and paste entire node graphs. But there is a hard heap limit of 512 variables per graph node.

Gameobject --> get.transform --> get.position --> navmesh Set.destination. will spin up 3 additional variables and allocate storage for them in assembly.

To get around thus you want to get and save all variables you make in the graph.

Also if graph starts lugging it's best to turn off auto compile.

[vale fox]

or not use graph and learn c#

[coral sun]

I mean if graph works for you, go nuts

[zenith imp]

Text based coding would work for me if I've spent the last 10 years thinking and solving about abstract problems instead of visual thinking. But alas my brain gets all jumbled when looking at a wall of text.

I can follow and trace paths on a node graph.

[vale fox]

I learned coding in like a year, it may be a lot more within your reach than you may think

[hardy robin]

I havent understood udonsharp either. When it comes to it, Udongraphs and cyantrigger are where i excel at.

[vale fox]

To each their own, but the traditional programming medium is the way it is for a reason, and theres a lot of potential to be tapped by being willing to learn a new skill

But! Of course! A good workman can make beautiful things even with crude tools, and i am always impressed by the stuff i see people do in graph

I just am scared for the sake of their sanity

[hardy robin]

It can sometimes get tedious when its gets so huge. Honestly, UdonSharp is one of my next goals. Im not sure if its faster or not but I bet when i eventually hop on it, I can learn some new things that i can utilize.

[vale fox]

Learn c# instead of udon#

Its literally the same thing but you arent restricted to unity and can just run everytjing from vscode

[zenith imp]

I'm using udon graph to learn the basics of programing and how to think. It allows me to see the connections.

Otherwise it's nothing but. "Hey whats ! Do? Why is < here? What's $ do? Why? What? I don't understand. Wait... holdup... }{? Hvgi53?"

Seriously I've tried for years. I have programing books. None of it clicks.

[vale fox]

Haha its hard to find the learning method that works for you, but i seriously think anyone can learn coding

Its about finding the right way for you

[zenith imp]

Problem I find is the language barrier.
Every Unity docs assume you know the entirety of C#.
C# docs assume you have 4 years studying computer science.

Most tutorials I've found on programing jump from basic concepts to SUPER ADVANCED.

It's like that meme. How to draw an owl:
Step 1: draw a few circles
Step2: draw the rest of the owl.

[vale fox]

Might be a little off topic atm lets swap channels

[bitter atlas]

I like whatever Gamemaker uses for its language, it has been very approachable for me before I knew anything about programming xd

you can use keywords like if a is true or b is true {} and you can use = and == interchangeably and all ; are more or less optional

looking back on it it hurts a little but its room for mistakes is probably what made me not quit xd

[quartz torrent]

One thing you could try is get the package 'UdonFlat'. This automatically creates a U# version of any graph. You can then compare them side by side with code you're familiar with.

[bitter lintel]

Udon2 will do that too right? (convert graph into readable c#)

[quartz torrent]

2 isn't going to be out for a while

[stable phoenix]

https://gitlab.com/lox9973/UdonFlat/-/tree/master

[coral sun]

From what I understand it is essentially a more feature complete backend, but there will still be a division for c# style udon and udongraph

[dawn oxide]

Health/Stamina and food/water in development for my RP project

Hunger and thirst system, working right now on the prefabs for eating and drinking

[dawn oxide]

[bitter atlas]

[dawn oxide]

Yes

[zenith imp]

My "NPC Identifies the other copies of it'self finds the nearest one and send that one a message to wait a reply" code.

The "time out module" it sends a different reply if it does recieve a ping back from the other NPC

This is an action script. It can only work in conjunction with the dispatcher script.

Dispatcher script: Recives inputs from various sorces. Mostly pays attention to the Brain Script. It takes the update loop and plugs it into the other scrips powering them when needed. So it kinda works like a switchboard operator.

My planed sensory script will be plugged into the Dispatcher script as a form of an interprupt variable. If something is important, the dispatcher script will alert the brain script. Brain script will determine if the interuption is worthy of switching action states.

[simple berry]

You should maybe look into making a blackboard architecture for your ai to communicate w/ each other/remember information if you haven't already.

[zenith imp]

Blackboard is coming later. That's the long term memory module

Currently my NPC only remember their current decisions, that information gets networked. Then all code is executed locally

@simple berry

I'm currently building out the animation state sync. And the dynamic ownership transfer at a individual NPC level.

[simple berry]

Noice. I really should mess around with ai in udon. Made some stuff for some hobby unity projects before but handling the networking side of things'll be fun.

[zenith imp]

I'm not a programer, but I'm learning programing through udon. What I do bring to the table is 20 years of character animation and art. So I'm really excited when I start getting into udon fine tuning the character animation. (Npcs looking directly at specific players, adjusting timing to be more dramatic)

I want to entire a realm of fidelity that not many programers approach with their project.

[low meteor]

that look actually insanely interesting :o

[zenith imp]

They actually work right now at a very basic level. They have about 7 behaviors.
Walk
Walkshort
Walk far
Run
Idle
Proximitycheck
Wave (this is two npc syncing up and swapping info. This allows for actions that would require more than 1 npc action. [Like kissing, or getting into a fight])
And BONK! (when the navigation fails)

But the foundation is being laid down for an infinite behavior tree

[low meteor]

Wish you the best :D

[frank lily]

This is extremely amazing

But I think getting it into code form would be way easier to maintain in the future

It might be worth the effort to learn textual representation

especially as udon nodes are basically functions, but instead of putting stuff in parenthesis, or in appropriate method (update, oncollider enter etc) you connect stuff with a spaghetti

Initial hurdle might be high, but you'll see how some of your big chunks can be written in one line

[dawn oxide]

Each player have own life parameters, dynamic and all synced, monitors reacting for the change like irl, late joiners also get the correct parameters, each player life parameters are local until player closed enough or monitor is connected

Thank you ^_^

now I'm curious to find out what happens on a star citizen one XD
Also thank you 🙂

[quartz torrent]

That looks super cool, curious if you're doing the trick of moving the world rather than the elevator? X3

[weary kelp]

Thanks and no, world isn't moving. its the elevator moving up and down 🙂 Using Superbstingray's platform hook so I can have players stick to colliders without floating away if a platform is moving down or sideways.

[tribal egret]

Udon data persistence using log parsing plus a local webserver and string loading!

It allows you to save & load data from udon, as long as the player is running the program in the background

Might release the program and udon devkit for world developers if people like the idea!

requires very little code for the developer too

[coral sun]

Looking at the log, im guessing you are abusing debug.log here a bit? Looks fun lol

[tribal egret]

yup

[coral sun]

yup, I have seen a couple of people doing this stuff, but afaik there is no easy to use package others to use yet

[frozen summit]

So you can actually read the game's logs from inside udon?

[dawn oxide]

That's sounds great. Would love to play around with it if you do release it.

[coral sun]

Debug.log is a unity function that spits out given strings to a debug log that vrchat stores to disk

you can abuse it to send out arbritary data

and then you can have a program read it to do stuff

I am using this for some stuff as well actually

but you cannot read it from udon (or unity) afaik

the log file is only persistent per game launch, it gets moved aside and eventually deleted after every game launch

so if you want to do persistance, you probably have to import the logs elsewhere

[tribal egret]

no it's an external program that reads the vrchat log, the udon side logs instructions to the vrchat log which the program executes. (atm only instruction is to save data) The program also has a local web server which the udonsaves script will send a request to and get a string response with all the data, which is then processed to be able to easily access it

[coral sun]

yup, that sounds about right

I know actual official data persistence is a considered thing... eventually, but stuff like this are great stop gaps to at least experiment with the concept until then

[spark arch]

Can this send data to the string?

[tribal egret]

wdym?

[zenith veldt]

This is something I have been wanting to do for a long time. Kudos! I am interested to add/implement Microsoft SQL support for database management since I am working on a "VRChat" world manager solution one can configure user "Roles/Ranks", track scores, join count, show saved Rules/MOD, etc. Just be careful, VRChat might claim this is against their terms since they're picky about exfiltrating data but I hope to see a solution supported like this. If VRChat is a sandbox for creators, there should be options to collect/save data as long as it respects privacy. I've done similar stuff with Garry's mod management scripts and other games that are open to modding and have HTTP Clients one can use to make calls.

[tribal egret]

it's not modifying the client in any way, and you pretty much can't get any sensitive data from worlds aside from usernames I guess, so should be fine?

[spark arch]

Yeah, it should be fine. They might say something to you if you plan to release it publicly.

[tribal egret]

if they actually don't like it hopefully they'll just let me know so I can take it down before they outright ban me or something lol

[spark arch]

AvatarImageReader was warned by vrchat. Is what I heard so possibility.

[tribal egret]

really? that literally has the same capabilities as image loading

or string loading

[zenith veldt]

Should be absolutely fine, I know you're tailing the log file. Even without Udon people can still pull data. The problem is that if I am regurgitating data back into the map from my DB/Data collected, they might make the connection and it's a user/creator problem, not with your solution.

[spark arch]

Yeah. But there are certain things you can to abuse these systems.

[hard sphinx]

It is the method that makes it bad, changing the image for an avatar costs VRChat in server usage, image and string loading does not, or at least that is how I imagine they would argue.

[tribal egret]

ah ok so then this should be fine as it doesn't use their servers at all?

[hard sphinx]

It falls into the grey zone, they could warn you, they could also not, doubt they would warn you unless this starts becoming a common way to do persistence.

[coral sun]

Honestly I dont think this will become a defacto standard cause most people wont run applications on their pc for the use on a handful of worlds. This could be an interesting thing to experiment with persistence until it becomes an official feature

[gaunt night]

The "problem" here is that End-Users have to install unknown software from a third-party and run it.
VRChat may or may not be concerned about that, but ultimately there is nothing they can do legally to "prevent people from installing software on their own computer" or "prevent people from making software that reads VRChats log files"
So you're fine.

However it is generally a bad idea to download and run software from an unknown/untrusted third party. So this method is inherently "dangerous" for the user if they do not trust the author (you).
Its a risk-over-benefit thing (as with all software you download and run that hasnt been certified by an authority that is generally seen as trustworthy (e.g. Steam))

[tribal egret]

same goes for OSC programs, plus if I do release it it'll be open source

VRCX reads log files too

[hard sphinx]

Worlds requiring third party software is different though.

[tribal egret]

not require, though of it more as a quality of life thing, like saving settings or highscores

though that depends on the world dev of course

[gaunt night]

Yeah the other "problem" is that the software (even if you trust it) needs to run either constantly, or you have to manually start it before "using" it.
The first case is rather invasive and some antivirus programs might falsely flag your program, while the other case is rather unconvenient.

I guess an alternative way would be to have a modified VRChat.exe which first starts the program then the actual VRChat.exe

That would work and is not against ToS

[tribal egret]

yeah think the best solution for that is an optional setting to start when steamvr starts

[gaunt night]

Hmm well that would only work "well" if the only SteamVR game you play is VRChat :P

[tribal egret]

yeah true but it's not very resource intensive since all it is is a really simple local web server an a log scanner, plus it's written in rust

but yeah that's why it'd be optional

[coral sun]

Think steam overlay. Starts with steam vr and you could even have a ui there for configuration. It could remain inactive unless vrc is running

[tribal egret]

yeah

[gaunt night]

You still dont want to have a program thats always running. That is generally considered bad practice.

[coral sun]

Again, I do want to be clear that only a subset of people would use this. Imo I see this as a great ways for devs to practice and experiment with persistence until something official comes along

[tribal egret]

yeah I know I'm not expecting any worlds to rely on it, but would be cool if some worlds would allow you to save settings or high scores or stuff like that

[coral sun]

Tbh I can see RPG style or story games using this as a save system, especially with that new json handler

[tribal egret]

yeah but when it's required a better solution would probably be https://github.com/Nestorboy/NUSaveState which stores data in avatar parameters, with the limitation being that you're required to change the player's avatar to read/write data and the storage space is very limited, so not very practical for saving settings & such

[gaunt night]

This was conceptualized long ago, however the argument was always that forcing users to install unknown software (even if its open-source) was A. too much of a liability and B. too much of an inconvenience
But good luck trying to get people to do that :>

[royal coyote]

It's rough right now, but I've made a menu script where you can set some world properties based on your location! Menu buttons are dynamically generated based on the search criteria. It currently only sets the sun rotation and has some display info from the weather API. It's my first project, but has been very helpful to learn Udon's abilities and limitations, the string loading has been something I've been looking forward to

[zealous ridge]

Here's my graph for seamless teleportation, feel free to replicate! Just change the X Y Z values of the Vector3 Addition node to the relative location of where you want the player to teleport to seamlessly.
