[frozen badger]

I understand, but in my case this deck is my attempt at the game manager type class

having it in "the game manager" is not fitting because how small a part of the game it is

and so instead, perhaps consider what I call the "ItemDeck" to be the "ItemManager"

Like, imagine a linked list. Removing an item from the center causes multiple elements to be altered, but I wouldn't put the remove functionality outside the linked list

And the linked list does not emit events when an element is removed or the Next pointer is altered, right?

[tender light]

Exactly. And again your game might want those events

[frozen badger]

That's what I'm saying, that can't happen

It's like saying I want random.range to emit events when it rolls a 7

The assumption that events are desired upon objects being chosen is incorrect, and stems from the belief that they are actual cards, right?

[tender light]

Not at all

[frozen badger]

Or maybe "discovery" means something else that I am unaware of?

In card game language it's also called a tutor, right?

Or is it more like scrying?

[tender light]

Yeah. I think MTG calls it that. Does not matter what the mechanic is. I will re-iterate the point one last time and then I give up.
Sooner or later you might want to put additional functionality on top of the players actions. The corruptor example earlier was great.
Its an encounter that is forced upon you. This logic should NOT be part of the data structure. It should instead live outside of it. That's all.
The class of Deck should JUST store data. Nothing more.

[frozen badger]

Sure, but if it just stores data then it's just a list

And if something says "the next encounter will be a corruptor" then that will be outside of the data structure

However, how to access the data structure, to me, makes sense inside the data structure

I.e "roll one random" or "get by tag"

[obsidian glade]

these functions are almost written already in the form of linq queries, e.g myList.Where(card => card is HealthType).Shuffle().Take(n);

[tender light]

That's exactly what the doctor guy was trying to explain is a bad idea. Because then overriding that behaviour becomes problematic. Its not something easily extensible. Its also something that is offten affacted by other game systems. Therefore a bad idea to couple it together.

[frozen badger]

Right because he envisioned stuff like "every time you pull a card, gain one health"

Or "if this card is drawn, lose one health"

[frozen badger]

Sure, I'll be doing stuff like this, I just need to keep track of the results as well

[regal olive]

I'm using the NugetForUnity package to import the ML.NET and supported packages into the project, but I am having trouble trying to get the System.Collections.Immutable package in the same way. The UI doesn't really do anything in that case. The other packages need this one, but somehow this dependency does not get installed with the others. What can I do to fix this?

[flint sage]

Ask the developers?

[regal olive]

I guess I can log an issue and wait.

[undone coral]

hmm nugetforunity doesn't really work

what is your goal?

like what kind of application are you making

[undone coral]

in @obsidian glade 's example, you get those linq functions and more for free by declaring an IReadOnlyList<T> implementation 🙂

[undone coral]

yeah in my experience the seemingly most elementary thing winds up interacting with other stuff in your game

there's an effect in spellsource that's like, "Your Draw effects become Discards instead"

and because the invocation of a spell function itself is data, and all the spell functions have the same signature - even though they are all different spells! - this turned out pretty easy to implement robustly

[undone coral]

honestly you have one of the more interesting problems that goes into this chat so apologies for all the attention it gets. get cracking!

i can keep thinking of real examples

Discovering from an opponent's hand - now you're not using the deck anymore

[frozen badger]

Yeah but a significant of them would be from card games, right?

[undone coral]

yeah just because that's what i'm familiar with

[frozen badger]

Like, there's no "Hand" to discover from as there are no actual cards

[undone coral]

here's a good one: "The next monster you would have encountered is put into your inventory as an item instead. You can face it at any time by using it"

😵‍💫

[frozen badger]

Right, that's like 4 layers down though

[undone coral]

Potion of Theft: "Discover an item from an enemy's inventory."

[frozen badger]

wouldn't it be easier to just pull a monster at that point and put it in an inventory

as opposed to waiting until the next fight

[undone coral]

yeah it would be a pretty complicated thing to do

these games are fun to make lol

[frozen badger]

I am having a time disjointing the effects as far as possible from the items, etc

[undone coral]

Lucky Armor: "Whenever you would roll dice, your unlucky 1s become natural 6s (or 20s)"

[frozen badger]

Like, pulling the effect "TeleportPlayer" out of the item and instead making it a generic effect

and then items are collections of effects

[undone coral]

yeah

[frozen badger]

Different effects are active/usable at different moments

[undone coral]

you can look more into the spellsource architecture - the caveat is spellsource content is authored by nonprogrammers but who can think procedurally - in short it kind of looks like this

// teleport anywhere within 5 units of the player
public class TeleportationPotion : BasePotion {
  public float radius = 5f;
  public float castingTimeSeconds = 0.8f;
  public override async
 UniTask<CastResult> Use(GameContext gameContext) {
   var target = await gameContext.SelectTargetCoordinate(
    new RadiusSelector(
      center: gameContext.player.transform.position,
      radius: radius));
   var teleportationSpell = new TeleportationEffect();

   teleportationSpell.castingTimeSeconds = castingTimeSeconds;
   return await teleportationSpell.Cast(gameContext);
  }
}

public class TeleportationEffect : BaseEffect {
 // this would be pulled up into base effect since
 // lots of stuff will have cancellable casting time
 public float castingTimeSeconds;
 public override async
 UniTask<CastResult> Cast(GameContext gameContext, Target target) {
  // throws operation cancelled and propagates up
  // if the user clicks the X button in the UI
  
  // time spent casting
  // if the target (the player) is damaged while casting,
  // cancel everything
  await gameContext.DamageCancels(
   target: gameContext.player,
   effect: async () => { 
    await UniTask.Delay(TimeSpan.FromSeconds(castingTime));
   }
  );
  
  // this will eventually be gameContext.Teleport() when you
  // want more advanced teleportation rules
  gameContext.player.transform.position = target.position;
  return CastResult.SUCCEEDED;
 }
}

[frozen badger]

Yeah, but that is still an item in that sense right

I want my non-programmer compatriots to be able to set up items themselves

[undone coral]

almost ready

[frozen badger]

so I'm working towards getting the effects into dropdownlists they can pick in the editor

on the scriptableobject for the item

[undone coral]

i think it's better to create Bolt objects

because lots of games try to have you program in the inspector

and it's painful

anyway i hope that is illuminating

this stuff is easy enough to program

that usually getting the text is more valuable than your colleagues being able to program it themselves

does that make sense?

you should ask them to write text

until your game is more mature it's hard to do the thing where you program using data

there's a lot you would have to know intellectually - if you want it to be useful, the data representing the effects has to be context-free, non-polymorphic and homoiconic - that is just

a huge leap

@frozen badger a lot of stuff is too hard to program as data - https://github.com/hiddenswitch/Spellsource/tree/master/spellsource-game/src/main/java/net/demilich/metastone/game/spells/custom or see the equivalent in XMage

https://github.com/hiddenswitch/Spellsource/blob/master/spellsource-game/src/main/java/net/demilich/metastone/game/spells/custom/BaulPocuseSpell.java

in that second link @frozen badger you can actually see a concrete example of exactly what @obsidian glade was talking about

java streams == C# linq

https://github.com/hiddenswitch/Spellsource/blob/master/spellsource-game/src/main/java/net/demilich/metastone/game/spells/custom/CelestialConduitSpell.java < this is a tough one

[frozen badger]

Sure, but this also is a card game right? And so there is a lot of "Card interaction" so to speak

same as like, slay the spire

[undone coral]

well

yeah but same in any RPG

[frozen badger]

Not really, like the fireball spell rarely changes the ice bolt spell

[undone coral]

have you used the starcraft 2 editor at all?

[frozen badger]

Like, in this case the only thing that is similar to a card game is how stuff is handed out

no, I used the wc3 one a lot

[undone coral]

okay

so you would know how it's like, a tree of random crap

to implement spells right

this is very similar

[frozen badger]

Sure

[undone coral]

this is what the implementation to the WC3 spell system looks like... sort of.

the differences are academic

like they have an explicit, poorly implemented copy of half of basic LISP AND the virtual machine used to run it. i just do the first half

the examples i wrote for you in c# are nice because your game stack looks like your c# stack. in WC3, it is not

so like if you threw an error in the example i showed, using async, it will correctly show in the stack like, what UI button press was associated with casting the spell

[short fog]

Hi, how can i make a dribble system for a football game like this?

[wet burrow]

Because I get errors saying my struct doesn't support the equals operator

[pliant crest]

huh TIL to compare structs you need to override the equality

never needed to do that apparently

[candid lodge]

which is less expensive way to find closest gameobject unity ? looking to make shoter game

[jolly token]

ValueType.Equals automatically call Equals for each members, but causes boxing
And no default == operator for structs

[pliant crest]

did you still need help with the overrides?

    public static bool operator ==(Test lhs, Test rhs) => lhs.Equals(rhs);
    
    public static bool operator !=(Test lhs, Test rhs) => !(lhs == rhs);
    
    public override int GetHashCode() => (Id, Name).GetHashCode();

    public override bool Equals(object? obj) => obj is Test other && this.Equals(other);
    
    public bool Equals(Test p) => this.Id == p.Id && this.Name == p.Name;

[jolly token]

Also implement IEquatable<T> when using the code ^

[pliant crest]

ahh yes

afaik i've avoided boxing in this as well

(obviously replace Test with your type)

[jolly token]

Yeah if it implements IEquatable<T> then EqualityComparer<T>.Default would not do boxing

[wet burrow]

I posted in several places and got a bunch of different responses, I'm reading through all of them now.

It's great to get a lot of them so I can figure out the common rules, in case there are multiple ways to do it, so I can figure out what's best for me

[pliant crest]

this is the eh

standard way

[pliant crest]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/statements-expressions-operators/how-to-define-value-equality-for-a-type

[jolly token]

Wait for C# 10 then we can use record struct 😄

[wet burrow]

So obj is Test b simultaneously checks if it's that type, and declares it as a variable referenced by b, at the same time?

[pliant crest]

pretty much

b becomes the type Test as well

so its like testing and casting at the sametime

[wet burrow]

public override bool Equals(object obj)
{
    if (ReferenceEquals(null, obj)) return false; // Checks that it's not null
    if (ReferenceEquals(this, obj)) return true; // Checks if it's the same
    if (obj is CategoryTag b == false) return false; // Checks that the object is the correct type
    return id == b.id && name == b.name; // Checks the values
}
public override int GetHashCode()
{
    return id.GetHashCode() ^ name.GetHashCode();
}

I made these, they don't show any errors so I'll need to see how they turn out

[pliant crest]

you shouldn't do that

you should have one source of truth

not multiple @wet burrow

unless for some reason you don't have Equals that takes in your type

[wet burrow]

so I should have either the equals or the gethashcode but not both?

[pliant crest]

na

your equals is doing the comparison

but its the object version

return id == b.id && name == b.name; // Checks the values

that should be in the typed version

its also a struct

so i have no idea why you are doing reference checks

[wet burrow]

I saw it in a forum post and realised the guy in it was making a class and not a struct

[pliant crest]

well you can zombie together a solution if you want

but make sure you understand what you are doing

don't just copy paste

[wet burrow]

I guess that's one disadvantage of getting a bunch of answers from different places

[pliant crest]

i've given you a complete solution

just remember to implement what cathei said

or make your own based on the microsoft article i've sent you

all roads should lead to the same answer thou

[wet burrow]

As in any gameobject? How often are you calling this function, and for what purpose?
An easy solution would be to simply use FindObjectsOfType using the GameObject type, then iterate through a for loop getting the Vector3.Distance values between their transform's position and the specified position you're checking against. Then get whichever object has the shortest distance

A more performant solution would depend on what you're trying to do

Or you could use SceneManager.GetActiveScene() to get the current scene data, then get its GetRootGameObjects() function, and iterate through those and their children

[wet burrow]

thanks for the info @pliant crest

[lyric dragon]

Hello guys,
I am currently working on animating the eye movement. I want the eyes of one of my models to follow the camera.

I watched some youtube and made something that satisfies my needs, but there are few problems.

I did something like leftEye.transform.LookAt(camera.transform), but the orientation of the eye doesn't really match the iris position, so instead of following the camera with the iris, it follows it with eye's white.
My workaround was to find an appropriate rotation such that it makes iris follow the camera.

leftEye.transform.LookAt(camera.transform); 

leftEye.transform.Rotate(new Vector3(10, 90, -13));

This is the approximate code which is put into the void LateUpdate()

I figured out those 10, 90, -13 values by hand, by constantly tweaking a little bit and running over and over again in the editor.

It works fine, but as soon as I move camera to the sides, the eyes do not follow the camera, but somewhere ahead of the camera, this results in model's eyes looking ahead of camera position.

How do I dix that?

Hi, I have a shadergraph that has 6 possible textures and I wanna be able to expose UV channel selection for each texture, but I've ended up with over 1200+ shader variants being created

is there a better way to not end up with 1200+ variants

[compact ingot]

Depends on what exactly you mean by that. Do you want to subdivide a polygon shape into a regular square grid?

maybe draw a picture of what you want

[compact ingot]

avoid branches or combine them into variations that you actually need

[crimson ruin]

RectTransformUtility.ScreenPointToLocalPointInRectangle looks bugged, it doesn't account for scale even though it has all the context to do so. If change scale of the target RectTransform between two calls I get identical value even though this should ever be the case if the point happens to be straight on the pivot, which it isn't

[compact ingot]

you should never scale rect transforms

[crimson ruin]

How so? Seems to work as expected

[compact ingot]

it just makes it all weird, the math behind it is very lossy

you can use scale to do local effects, but you should not use it for layouts

[crimson ruin]

Ah, I guess there could be rounding issues since I guess it's in pixel space really

I need to for a world map type of deal where you can pan & zoom

[compact ingot]

afaik the whole ugui system basically ignores scale

[crimson ruin]

So it seemed kind of intuitive to just scale & translate

[undone coral]

why would the two be related?

[undone coral]

do you have any screenshots of your game?

[devout hare]

Need a bit more details than "does not quite work"

[sly grove]

Because both are basically outside assemblies dealing with your game assemblies from the outside

[regal olive]

I'm trying to use ML.NET in Unity for a classification task. I will script and train the model externally, but I will use the trained model inside the game.

There are some restrictions (based on the 4 year old sample ML.NET has for Unity). It's problematic to find the DLLs necessary to make it all work.

[undone coral]

are you familiar with unity barracuda and onnx

[regal olive]

I have heard of Barracuda. Will it be suitable for developing a C#-only model?

[undone coral]

what is a C#-only model?

what are you trying to do?

[regal olive]

Well one I could script only using C#. I am doing this for an assignment so I can't use anything apart from C#.

[undone coral]

okay

so it sounds like you are new to all of this

[regal olive]

The next thing is I don't have a lot of data, so I have been advised to generate synthetic data by taking the only sample I will create manually and adding noise to it to generate more data.

I have very brief experience working in Python and Java for sentiment analysis tasks but this is not my primary field!

[undone coral]

is your model a neural network?

[regal olive]

It could be a Recurrent NN but that's not a strict requirement. I could basically use a stochastic model as well in my case.

[undone coral]

okay

personally i would suggest to not use Unity at all

it's way beyond your abilities

it sounds like you are very new to this

[regal olive]

I am literally making a game in Unity.

I have to do this, new or not.

[undone coral]

what is your goal?

what are you trying to do?

like big picture

[regal olive]

To train a model to classify different types of "standard" (not mathematical) knots.

[undone coral]

no i'm saying

what is the game, what are you classifying

what is the idea

[regal olive]

The game itself is a simulator of sorts where the player gets to toe knots in different scenarios.

[undone coral]

were you trying to create a rope in VR earlier?

you were

[regal olive]

The model should just be able to classify what knot it is based on data taken from the rope. In this case I am generating a Centripetal Catmull-Rom spline from the rope segment centres, taking a pairwise difference of the coordinates, and passing them off as a long vector of floats (split into x, y, and z values).

[undone coral]

so now you want to classify the knot some how?

okay

to use an ML model in unity, the best workflow is to export it and its trained weights in the ONNX format, which ml.net supports, and load it with barracuda.

[regal olive]

Exactly. I have been able to make a sort-of VR simulation of a rope. Now I need to tell knots apart.

In that case, I'd have to make the NN in something like Tensorflow, which may not be suitable, I am guessing. But I like the idea of using Barracuda to load the model.

[undone coral]

i don't know if it makes sense to do this generally, you will be able to figure out what knot is tied analytically

[undone coral]

huh?

you can make the neural network in ml.net

you can do whatever you want in ml.net, and export the model to the onnx format

that said, nobody does this, so it's going to be full of bugs

[regal olive]

Yes! That's what I was thinking as well.

[undone coral]

nobody uses ml.net 👀 and nobody uses barracuda

these things have 0 adoption

you should probably determine the knots analytically. i'm sure if you punch it into google you'll find something

gotta go

[regal olive]

Do people use ML Agents for classification tasks, because from my experience we were basically doing RL there.

[undone coral]

nobody sophisticated uses ML Agents

all of this stuff has a rounding error of adoption, so it has a lot of bugs

[regal olive]

I searched far and wide but I got nothing. I'm running out of time as well tbh.

I'll take a look at the other approaches and see if I don't spring a trap full of bugs.

[regal olive]

Me too. Can I ping you later?

[undone coral]

okay based on some light googling

my suggestion is, don't do this lol

is it essential to identify the knots? what about making some funny gameplay instead

[opaque cape]

Hello, i got a 2d grid array how do i target the outline of the grid to spawn stuff like resources.

[undone coral]

like tying the rope around a bunch of different funny objects as levels, and they are your qwop game

[undone coral]

the algorithm you are looking for is for "edge finding"

when you say outline of the grid, you mean the "walls" in this cave right?

[opaque cape]

Yes

[undone coral]

praetor also gave you

a way to look for adjacent nodes

you can visit every grid point and check

[opaque cape]

I see, thanks for the help.

[weak prawn]

Hi, I just found out that most of my methods under Update() is being called every frame which is really not ideal, can you please share your ways on how you deal with Update()? For example, when my Character is wall running, I want the Raycast to stop being called. But when I jump or switch to another Wall, I want it to be called.

[tribal pivot]

#854851968446365696 dont crosspost

[regal olive]

My mate, IDing knots is the main function of my project!

[undone coral]

lol

okay well

[undone coral]

since you know a lot more about this than i do - if i showed you a picture of a knot, which is a rope and clearly you can see at every intersection with itself (or another rope), which rope is "under" versus "over" - would you be able to identify the knot?

i think i could identify most knots, analytically, if they were "drawn" in 2d (which is really three dimensions, x z and "over" versus "under")

of the form intersections of rope (t1, t2, over or under) maybe?

if it were a single rope

[regal olive]

The data is directly the coordinates of a spline representing the rope, and not some image.

[undone coral]

where t is the distance laong the rope

yeah but

listen it's not going to just, work

you're not going to be able to do program finding with ML.net

[regal olive]

I get what you're saying. There are existing projects doing knot image recognition.

[undone coral]

if your project is all about IDing knots

surely you've made an attempt at doing this analytically

where did that go?

[random dust]

Does anybody know if there is a way to check if a string can be deserialized into a json object or array without throwing unnecessary exceptions? Right now I check if an exception throws when I try to deserialize the string, because I could not find an alternative. Relying on exceptions is a bad practice so I want to avoid it.

// Try to deserialize the string into an object or array if possible.
            try
            {
                responseObject = JObject.Parse(responseBodyUnparsed);
            }
            catch (JsonReaderException)
            {
                try
                {
                    responseObject = JArray.Parse(responseBodyUnparsed);
                }
                catch (JsonReaderException)
                {
                    responseObject = responseBodyUnparsed;
                }
            }

[undone coral]

are you asking if there's an IsValidJson method?

[random dust]

Pretty much

Is valid json object or is valid json array basically

I could check if the string starts with { or [{ I suppose, but I was hoping for a more reliable solution

[undone coral]

lol

https://grep.app/search?q=isvalidjson&filter[lang][0]=C%23

it's pretty grim out there

[regal olive]

Not yet! I'll explore that option too.

[undone coral]

i think you do try to parse it and see what happens

[undone coral]

well if this is all your project is about then you should be spending 110% of your time doing this

a neural network isn't going to be able to do the dimensionality reduction into whatever form really simplifies a 3d knot, not without colossal amounts of data

you will have to figure this out!

[regal olive]

Which I can't because there's more work on total, but this is a start.

[random dust]

First link I check lol

Oh well, thanks 😛

[regal olive]

I'm afk actually, will elaborate further soon.

[floral notch]

Hey everyone, I've been very confused about this for several hours now(first time using raycast in code), I have this script attached to my main camera and I get the error "null reference exception object reference not set to an instance of an object" in line 31, I have no idea whats wrong, some help would be appreciated, thanks in advance

[autumn topaz]

how do you make a jagged nativearray that refrences a struct?

@undone coral there's a way to simplify the process a model will take to identify a knot.

We take a given set of spline coordinates and first take their pairwise differences into some buffer. This allows us to immediately remove any dependence on the transform or other positional property of the spline. It can also be normalised since the distance between each spline point is always the same.

We can easily generate synthetic data from these differences by adding some noise to each point in this new buffer, and then perform some manner of dimensionality reduction using PCA or similar as a preprocessing step.

Of course, the main pain point is how I would consume the model, but I guess the first two steps are within my reach.

[signal reef]

Does someone know how do I make some code in FixedUpdate() occurs before other script that also uses FixedUpdate() in it's logic?

[severe topaz]

there was something in project settings iirc @signal reef

[regal olive]

Change that script's Execution Order.

[severe topaz]

i didn't know that mouse has z @_@ or does it just set 0?
either way it should've been fine, but from the colors it looks like VS isn't set up properly

[signal reef]

Oh I googled it here, gonna try it, thx man 🥹

[floral notch]

This is supposed to detect depth for thr raycast, but im not sure, thats what im having trouble with, and the error it displays confuses me too

[severe topaz]

i see the problem on 32 but not 31, so again it's more likely that VS not being set up for unity might be causing it

honestly just remove that line

[floral notch]

How would I set it up correctly I thought I did everything right.

[severe topaz]

i checked docs and Z isn't used for screenpoint to ray

depth of ray is what you have set to 100

[floral notch]

huh, weird, you mentioned an error in Line 32

[severe topaz]

yeah, that was it and i double-checked it, i still have no clue why it'd bother reporting 31

you don't have to assign anything either if you're not reusing it, it'd condense into
if(Physics.Raycast(camera.ScreenPointToRay(Input.mousePosition), RaycastHit hit, 100f))

if it says null then it's probably camera not being assigned properly

[floral notch]

oh interesting, ill give it a go

[severe topaz]

wait, is there a camera in the scene?

[floral notch]

yes

[severe topaz]

then yeah check how to configure VS for unity if it still complains

[floral notch]

alright, Ill need to check

[hushed plume]

given the wall's normal and the objects velocity, what should the resulting object's velocity be after a collision?

right now i've got
(velocity+Vector3.Reflect(velocity,hitnormal))*velocity.magnitude;

but that doesn't seem to be working

[jolly token]

If it's completely bouncy then just Vector3.Reflect should be enough

[hushed plume]

it's not bouncy

[obsidian glade]

what are you actually aiming for, and what's the reasoning behind adding the velocity and then multiplying by magnitude again?

[hushed plume]

I'm aiming for a velocity that doesn't go into the wall but still goes along the direction it was going in. adding the reflected velocity should cancel out the movment towards the wall

[obsidian glade]

and what isn't working about it?

[hushed plume]

going through the ground

also bouncing sometimes

[undone coral]

We take a given set of spline coordinates and first take their pairwise differences into some buffer. This allows us to immediately remove any dependence on the transform or other positional property of the spline.
the knot could start earlier or later in the spline
the first bend could be in any direction...
sounds like there are a lot of things you would have to do to reduce dimensionality

which is sort of something neural networks are good at, but on the other hand, you will have to generate thousands to tens of thousands of examples

possibly per class

which is way out of scope for you

you should really try to do this analytically first

when is your deadline?

[analog verge]

After starting my game on Nintendo Switch, the application get freeze if I touch fast the screen immediately after starting. I think the application was loading Resources folder contents at that time. Does anybody know about this issue?

My bad

[dusky kettle]

hey guys, so say I want to write a script that scrolls a material offset at a constant rate
what is the most inexpensive way to go about this?
my thought is to utilise the jobs system, but it feels like all that would do is make another thread add a number to another number and that it would be more computational power initialising the job than it would be actually doing the math
I just wanted to know the absolute best way to do this so I can do it at scale and not have to worry about performance being left on the table
and sorry if this doesn't count as code-advanced, I just wanted to cover all grounds in case the method turns out to be super complicated

ill try and find where I wrote to do it earlier

[undone coral]

you can set the material offset to Time.time. why would this be expensive?

[dusky kettle]

thats a good point lmao

im not sure i just thought maybe there might be a very technical better solution that might bypass some unity processing on top since the way unity scripts work seem to be kinda higher level

i dont fully understand how unity works yet, still learning

[vast shale]

if it's the same for all objects you could also just use a shader global. slightly more control than time.time inside the shader

hello how can I compare "Module" arrays' "moduleId" attribute with each other to see if it is repitetive?

That is soo easy I know but could not do it.

if two objects have moduleId 1, for example, it will return false

[regal olive]

I was thinking about this earlier! The data could be shifted on its axis by some set of indices. Half of the data could also simply be flipped about the central index.

[regal olive]

I need to get this up by Dec 19, along with some other stuff like some basic scenarios demonstrating certain knot types.

[regal olive]

For now I won't be doing more than 3 types, so just one overhand knot, and a few other hitches and bends should be enough.

[crystal galleon]

I want to make a class serializable, but on Deep Copy (via JSONUtility.ToJson/FromJson), I want it to ignore a specific field, which stores a Scriptable Object, which are NonSerializable. How could I do this? I do need to make a custom serializer, but I'm clueless

[regal olive]

Simple overhand knots are easy to make, and the weird spikey gizmo is essentially a representation of the normalised coordinate displacements.

I can record a number of different configurations like this and then proceed to synthesise more data from these original recordings.

[vocal dagger]

Not sure where this belongs, im playing around with unitys IK.
However, i want that the whole upper body of my player moves to reach the target with his hand.

How do i do this via code ?

[vocal dagger]

Anyone ?

[severe topaz]

probably the exact same way as when you tell character to walk up to the object before picking it up

[sly grove]

That's the whole point of IK

every bone along the tree will move somewhat to get the end effector to touch the target

you don't need to do anything in code

[vocal dagger]

Weird, in the case of unitys inbuild IK it did not. It only moved the arm, not the upper body

Another topic, how could i ensure that a rigidbody only moves within a certain area ?
I did some clamping and check of the z/x position... however this stops working as soon as i rotate my game... which is quite common in my case.

Glad for any help, have no idea how to solve this

[sly grove]

You have to configure it properly to include all the joints you want to move

[sly grove]

Use colliders to confine your objects in a physical space

[vocal dagger]

Thats not the problem... clamping is the problem... imagine a AI which only moves a pug within a certain space like this to defend its goal :

        // Pug is in the players half, return ai back to its starting position for defending. 
        if (_pugTransform.position.z < _remoteBoundary.Up)
        {
            movementSpeed = MaxMovementSpeed * Random.Range(0.1f, 0.3f);
            _targetPosition = new Vector3(
                Mathf.Clamp(_pugTransform.position.x, _remoteBoundary.Left, _remoteBoundary.Right), 
                _startPosition.y,
                _startPosition.z
            );
        }

For this colliders can not be used

And it works, but only for a fixed rotation of the game table... once the game table is rotated it messes up

I basically need some vector3.clamp to keep a vector3 between two other vector3's which act as some sort of line/border

[sly grove]

I'm not sure why colliders can't be used, but you can also just put this bounds stuff on a GameObject and rotate that. Then use transform.TransformPoint to transform your boundary "corners" to the appropriate places.

Your code clamping on individual world axes will have to change though

you'll need to just do some simple vector / Plane stuff to confine the points

[vocal dagger]

Thats the problem the code clamping, i just have no idea how i should to that. Rigidbodys move within world space... and the code also needs to "rotate" or change axis or whatever... how do you do this normally ? Any code samples ? I cant find anything about this :/

[sly grove]

You can use Planes with stuff like:
https://docs.unity3d.com/ScriptReference/Plane.GetSide.html
https://docs.unity3d.com/ScriptReference/Plane.SameSide.html
https://docs.unity3d.com/ScriptReference/Plane.ClosestPointOnPlane.html

[autumn topaz]

I'm trying to turn a jagged array of a simple struct 'face' (public Face[][,] topFaces, sideFaces, frontFaces;) in my 3d block game a job, but I dont know how to convert this to a native array. Does anyone here know what I should do here?

[undone coral]

one consideration is to not use jagged arrays, since you don't have to

[sly grove]

Multidimensional arrays can always be flattened into 1D arrays

you can also use a NativeHashMap to map coordinates to the faces

[autumn topaz]

hmm interesting

I have done some searching and it seems like structs of nativearrays isnt possible either so I will look into it

[tough plank]

You can use Quaternions for rotating your boundaries vectors or whatever.

[autumn topaz]

Another question, I have started converting the 3d array into a 1d one but lambda functions such as this
Face GetFace(NativeArray<Face> inputArray, int sizeX,int sizeY, int layerIndex, int arraySize) => inputArray[(layerIndex * arraySize * arraySize) + (sizeY * arraySize) + sizeX];
do not work even though just accessing the array on its own works fine. why does this throw an error when called?

[sly grove]

This is the job system yes?

[autumn topaz]

yes

[sly grove]

SO I wouldn't expect to be able to use any lambdas really in the job system

lambdas are managed objects

allocating and working with managed objects in the job system is a no-no

[autumn topaz]

what about regular functions? do they not work as well

[sly grove]

static functions work

[autumn topaz]

ok will try that

I mean i could go without a function but you can imagine how much of a pain it would be in a script that calls this function 100+ times lmao

[undone coral]

this isn't a lambda, this is an expression bodied method

this needs to be declared static

how can i make basic character customization with photon

i can pay for help

I want to download a nugget package
IotaWallet.Net.Domain
and the error above occurs.
I am on a mac.
I did not find any .net framework 4.7.1 for mac to download an install nor can I change to .net 4x in the player settings

could someone please give me a hint how to get this package into my project?

[serene grove]

i just want basic customization like shoes and some other things

i have the models

anybody has photon example for help me

[kindred crane]

So its a multiplayer game?

Or are u using photon to... save data to cloud?

[serene grove]

basicallay

just a basic world

player just log in

after making basic edits

change hair

skin color

shirt top bottom

[kindred crane]

So ur using photon to store data onto a cload server?

[serene grove]

i using cloud

can we save

prefab data

and load them?

cloth1 activated after cloth2 deactivated

[undone coral]

this sounds like #💻┃code-beginner

[serene grove]

i think so

[kindred crane]

Beginners know how to save data to cloud?

[serene grove]

i researched but i cant find any doc

[kindred crane]

Ive never used photon but cant u just use whatever code is used to send data to the server to send data to the server

Also

It is less performant to save all the prefab data just save like a string for whatever the customised look of the plr was and then u can load that data onto the client side

[undone coral]

they don't but it's a good place to ask and get some guidance

[serene grove]

hmm

i checked assetstore

why we dont have any

multiplayer supported character creator

[kindred crane]

Cuz nobody made it

[serene grove]

;.;

if you could share a screenshot of what you have

maybe i can give a specific recommendation

[serene grove]

currently

i have 2 assets

can i post them?

here

@undone coral

[kindred crane]

Post ss of them not the actual models

@serene grove

oh

you didn't make the models?

i'm asking a screenshot of your game

Looking for feedback on how structure this. I have a technical artist who is creating many dozens of prefab one shot particle effects. I've got a number of gameobjects in a scene that I want to basically staple these effects to when they're relevant. Unfortunately, the type of objects isn't consistent. Some are icons, some are buttons, some are in-game objects, etc.

What I'd like to basically be able to do is instantiate one of these VFX prefabs at a time and point and scale in space, without tying the prefab to the object...

Maybe a scriptable object with a list of VFX and a getter that takes an enum to give me a prefab that I can instantiate and destroy from the object in question?

[rare sage]

Hi all, I've got two problems:

I'm working on a game where the game slows down when the camera is rotated by the player, otherwise it runs at 60fps with no problems. I've run it with MSI Afterburner and that confirms that the framerate drops down to 20-30fps whenever the camera is rotated, though it feels like less when you're actually playing the game.
I'm using the new input system to track the mouse delta, and the camera logic is just for a simple FPS camera. Here's the code for camera rotation:

float mouseDeltaX = _playerInput.actions["LookX"].ReadValue<float>();
float mouseDeltaY = _playerInput.actions["LookY"].ReadValue<float>();

Vector2 mouseDelta = new Vector2(mouseDeltaX, mouseDeltaY);
Vector2 currentRotation = mainCam.transform.rotation.eulerAngles;

currentRotation.x -= mouseDelta.y;
currentRotation.y += mouseDelta.x;

mainCam.transform.rotation = Quaternion.Euler(currentRotation);```

Can anyone see something that could be causing the slowdown, or know about other issues that can cause it?

I've tried connecting the profiler to the built version of the game, but whenever I use it it reports the game as running at 60fps, all the time.  Using MSI Afterburner at the same time as the profiler shows that the game isn't running at 60, which is fun.  It's probably connected to the first issue, but does anyone know why that might be happening?

[compact ingot]

Happy Turkey Day! 🦃

Looking for tips on how to debug a photon connection to master! (Specifically for WebGL using websockets)

Been at this for hours, connecting locally in the unity ide build works... the windows build works... (all call OnConnectedToMaster() and creates/joins a room)

but not in the WebGL build....

In the browser console with my debug lines I see that neither the OnConnectedToMaster() or the OnDisconnected() callbacks being called. Therefore, my cry for help to debug what is going on here. bool connected = PhotonNetwork.ConnectUsingSettings("1"); is true, so I read there should be at least some kind of callback...

Code in this thread. Thank you so much in advance!

[analog verge]

Does anybody know or suffered with similar issues?

[severe topaz]

that code is so cursed you could as well ask that in #💻┃code-beginner
but the fps drop isn't related to it

[rare sage]

Nope, URP for this project

[rare sage]

Any clue what the FPS drop could be caused by then? It only occurs when the mouse is moved to rotate the camera during gameplay, and that’s it. No clue if there’s some setting which causes this behaviour and has accidentally been enabled or something

[severe topaz]

https://youtu.be/5JN9n1Lsp8g could be this

[pliant crest]

why not just profile it

asking us isn't gonna help that much

[severe topaz]

but yeah ^

[rare sage]

I did, the profiler doesn’t report any frame drops

[flint sage]

That rendering graph looks like it's just more complicated and expensive rendering

Go disable vsync and see then

[pliant crest]

looks like most of their wait time is from vysnc

[rare sage]

Waiting on vsync isn't the issue, because that's expected if the game is actually running at 60 like the profiler says. If you read the original message I posted you'll see that the problem is that the game drops to 20-30fps when I rotate the camera and the profiler doesn't pick up on that, meaning it's not all that useful for finding out where the problem area lies right now.
I've tried disabling vsync and got the same frame drop behaviour, only with an unlocked framerate.
That video from Code Monkey seemed promising, but the game already has the input system to update on update() rather than fixedUpdate()

[pliant crest]

does this not happen in the editor?

[rare sage]

Yeah it does, when you run it in the editor you can actually see the big performance spikes in the profiler and inspect them, but the cause of the drop in performance just falls under "EditorLoop" which is supposed to disappear when you build the game and run it, but the same issue happens on built versions on the game which has stumped me

[pliant crest]

mind sending a screenshot of that?

[rare sage]

Sure, gimme a second

Big performance spikes caused by moving the mouse a little at a time, at the bottom you can see EditorLoop took 300+ms on this frame in particular

[pliant crest]

is this true throughout the spike?

[flint sage]

Enable deep profiling and see what is in there

[plush hare]

So I'm trying to write a component that attaches a unique ID to a gameobject in a scene for network synchronization purposes. All of the solutions online generate a GUID and then get the hash. This generates a very large number. Is there a way to do this starting from 0?

preferably assigning it only in the editor when the game isn't being played

[winter yacht]

I think this will depend on your networking solution.

[plush hare]

custom

[winter yacht]

I just increment a static integer every time a mob is spawned. This id won't be unique outside the mob type.

[plush hare]

It needs to be attached to scene objects when the game isn't running

a unique, persistent ID

I might go the GUID route, and then create network IDs starting from 0. When the client joins, just have the server send both GUID and network ID to map them together

that seems like the least frustrating route

[winter yacht]

Sounds like a plan.

[wispy lion]

I have done this for ScriptableObject

public class NetworkScriptableObject : ScriptableObject {
    [SerializeField] [ReadOnly] protected int networkID;

    public int NetworkID => networkID;

#if UNITY_EDITOR
    [MenuItem("Data/Regenerate NetworkScriptableObject IDs")]
    private static void RegenerateIDs() {
        List<NetworkScriptableObject> data = AssetHelper.GetAllAssetsOfType<NetworkScriptableObject>();
        for(int i = 0; i < data.Count; i++) {
            data[i].networkID = i + 1;
            EditorUtility.SetDirty(data[i]);
            AssetDatabase.SaveAssetIfDirty(data[i]);
        }
        AssetDatabase.Refresh();
    }
#endif
}

It requires regenerating when creating new objects, but you can use IPreprocessBuildWithReport to make sure they get regenerated when building. I feel like it should work the same with gameobjects.

(btw, I'm starting the NetworkIDs at 1, because the default for int is 0, so you can immediately know something is wrong if your id ends up being 0)

[regal glade]

I know there's some methods not entirely explained in this code, and it's a bit long so if nobody feels like it that's fine. But if anyone has the time I would really appreciate some input on how to speed this up. Basically I am doing some checks on tiles in a 3D array to determine whether they should be opaque, invisible, or semi-transparent based on character position and which room/building we're in currently, then I write this information to a 2D texture with SetPixels32 every frame.

The whole thing takes like 6 ms to execute and I kinda need to get it down, but other than re-designing it from the ground up I'm not sure if there's something else I can do, like change what kind of variables I access etc. I read something about structs above 16 bytes would be slower so maybe Color32's aren't great to iterate for example. Maybe I'm doing some slow things unnecessarily.

After line 262 the code kind of just repeats itself 5 times for different branchings

https://pastebin.com/enkXcJQF

[flint sage]

Have you considered doing this on the GPU instead?

(I'm not going to try to decode 600 lines of code tbh)

[regal glade]

Yeah that's fine I get that.
Do you think that could be beneficial? I am already doing some rather heavy raymarching with a compute shader.

[flint sage]

Sure, parallel execution is great

You can also just do threading on the CPU as well using Parallel.For for example

(Not for every tile but for sets of tiles)

[regal glade]

I did try Parallel.For but it slowed to a crawl. But I need to try it again as I think I wasn't doing it properly

[flint sage]

Of course depends on what exactly you're doing

[regal glade]

It was pretty difficult to figure it out with all the variables

[flint sage]

If you need to lock then it's slow af

[regal glade]

yeah do you need to lock for reading as well or just for writing?

[flint sage]

Depends

If you want to ensure that the data doesn't change until your calculation is done you need to lock from the read

But if you don't and you can guarantee that you won't write to the same indexes then you don't really have to lock in general

[regal glade]

mm right. i'm only reading and then writing information to a color array based on the information we're reading, so maybe if i can properly write to a buffer at the end or something. didn't quite get that part which is where i think the issue was.

[flint sage]

This all is assuming that your calculations are the heavy part and not the apply

also aplpy(false) is probably faster if you don't need mipmaps

[regal glade]

it's not the apply yeah i've tried that

oh ill try that right away

nah didn't make much of a diference

[regal glade]

Yeah Parallel.For with a thread limit of 4-8 seems to boost the frame rate a bit, from 120 to 180 or so. 12+ makes it slower again.

wouldnt mind getting it down more but it's a good start

[regal glade]

Paralleling the bottom most Y loop instead of the X loop popped it up to 300+ so I guess that's that 😂 Thanks for the pointers.

I have a tool class that i assign as a field in a controller script, by making a new Tool(), and it works fine, but if I change any unrelated variable in that script it's like all the tools get cleared and I get reference not set errors everywhere. Is there any obvious explanation for this?

I could do this before but I have no real clue what might have caused this sudden issue. The only thing I could think of was that I enabled unsafe code execution but I already disabled that.

[sly grove]

You'd have to show some code and the exact errors etc

[solar anchor]

this is not the solution as it works in vs without unity....

[rare sage]

Managed to find a solution to this, turns out a package I added to the project was taking up a bunch of frametime but it was only visible in EditorLoop, which is why the performance spikes weren't visible when profiling the built version of the game
Thanks to everyone who tried to help out though!

[solar anchor]

i installed nugget in unity and were able to get the nuggets. but I think the problem still stays. I cant access the commands

[regal glade]

@sly grove Don't really know what to show you. This is a bit of a mess but this is really pretty much all there is to it. I don't see how anything would cause changing a variable in the inspector at run time would cause such a wipe of the tools. If I debug.log the class itself I get (null) when it works, but once I change a variable it just spits out an empty space, while trying to print the .toolName it throws an error obviously.

Top script assignment is where it drops the tool

[sly grove]

wdym by "once I change a variable"?

can you show that in action

just seems like currentTool is null

I'd start by putting Debug.Log everywhere you're assigning that reference

If I debug.log the class itself I get (null) when it works,
Wdym by logging the "class itself"?

I don't see how anything would cause changing a variable in the inspector at run time would cause such a wipe of the tools
changing variables in the inspector will cause OnValidate() to run, for one thing.

[regal glade]

with the class i mean just Debug.Log("currentTool: " + currentTool); where currentTool is an EditorTool class

Yeah I don't do OnValidate either, only start and update and lateupdate

the variable (poop) i changed is not used for anything i just added it

[sly grove]

Is the EditorTool serializable/serialized?

[regal glade]

it's a normal monobehavior

i haven't set anything special for it when it comes to serialization

and this did work fine before so

[sly grove]

It's a MonoBehaviour that you created with new()?

[regal glade]

i have no clue what i might have done

[sly grove]

That would be your issue

[regal glade]

oh?

[sly grove]

You absolutely cannot create MonoBehaviours with new

[regal glade]

hmm alright let me try that

[sly grove]

they can't exist without being attached to a GameObject

Is there a reason it needs to be a MonoBehaviour?

[regal glade]

i was running Instantiate in another tool that inherits from the base EditorTool, to place gameobjects at runtime

but otherwise no if i can solve that some better way which i think i can

[sly grove]

You don't need to have it derive from MonoBehaviour to call Instantiate

Instantiate is a static method on the UnityEngine.Object class

You can just do using UnityEngine; and Object.Instantiate(...)

[regal glade]

yes! that solves it. thank you so much i would never have figured that out on my own, saved my day. 🙏

[solar anchor]

help please

[sly grove]

hav eyou tried regenerating project files?

[solar anchor]

I could reference the unity project to the other?

[solar anchor]

what do you mean? replacing them?

[sly grove]

no i mean going into unity external tools preferences and pressing the regenerate project files button

[solar anchor]

yes

[solar anchor]

You mean to get access to the commands?

[sly grove]

Can you clarify exactly what you mean by "get access to the commands"?

[solar anchor]

I need to use the librarx

[young wraith]

Hi is there a collider.bounds.min equivalent in texture

[sly grove]

Collider is a component

Texture is just an asset

[young wraith]

makes sense

[undone coral]

you can load a texture from bytes in the Texture apis

[potent shoal]

I've been looking all over for an answer to this issue, but I'm kind of lost. Does anyone know why this is happening?

how to change the targered .net framework to . net framework 6

it's always targeting 4.7.1

[sage radish]

.NET Framework 6 doesn't exist. You're probably thinking of .NET 6, which isn't supported by Unity.

[solar anchor]

ohh 😦 is there a way I could use this library anyway? https://github.com/IOTA-NET/IotaWallet.NET

i tried directly referencing the dependencies. that didn't work as one project still does target .NET 4.7.1

[solar anchor]

but is something like that possible? having 2 projects and calling from the unity project the pure vs project with .NET 6?

and is that even recommendable?

[violet valve]

.NET 6 is a buzzword that has nothing to do with Unity. I haven't read anything above this comment, but I can tell that someone is using words where they don't belong.

[violet valve]

Ah. So, .NET framework is a platform that targets features for windows. .NET 5 and beyond are actually extensions of .NET Core, which is a totally separate product from "framework". You're comparing Android to iOS here.

".NET 6" and Unity are beams that do not cross, despite similar naming conventions and the fact that both relate to C#. @sage radish EDIT: Sorry, I was pinging the wrong OP

[solar anchor]

ok sorry for mixing things

what do I have to do now to make it working?

[violet valve]

No problem, it was a confusing nomenclature before. .NET 5 was the first version of Core to basically make "framework" obsolete, but again this doesn't have anything to do with Unity in particular. It's more about web and form applications. I haven't read your initial query - I just wanted to chime in on this versioning issue.

[solar anchor]

here

[violet valve]

@solar anchor A complete answer might require some investigation; I'm sorry I don't have time to try to replicate the issue and provide first-hand feedback.

[solar anchor]

Could not install package 'IotaWallet.Net 0.2.8-alpha'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.7.1', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

[solar anchor]

ok

what would you recommend? or someone else? When I open a new vs project I can add the library without any problems. but if I make the project in unity and then open the project in vs...i get that error

[violet valve]

If you're using NuGeT, you might be able to to target a lower version. I don't really know the product so I am just spitballing here.

Generally speaking, Unity is best guaranteed to be compatible with .unitypackage files. If you're trying to hook into external dependencies, you might be on your own. One reason for this is that Visual Studio doesn't compile your C# code when working in Unity... the Unity Editor notices when the file system changes and uses it's own compiler to produce CIL. Have you noticed that you never build in VS? @solar anchor

[solar anchor]

hmm ok I see. could I build in vs the working lib and move the new .dll to the unity porject?

will the .dll contain the .net 6 or will it be needed again?

[violet valve]

Possibly - I don't want to promise anything. I would have to experiment a bit, which is probably your job at this point. IIRC, Unity is locked at C# version 10, despite the current modern version being 12 or higher, so it's possible that the resource isn't using the same language.

[violet valve]

Your video game is neither a website, nor a windows presentation application, so .NET 6 has literally absolutely no connection to what you are doing.

[solar anchor]

i could pay for the solution to use this lib in unity

I want to use it for webgl

[solar anchor]

not sure about that

[violet valve]

If you're offering to pay for someone to figure out if this is possible, I might be interested but am not immediately available to take a look... though I could try to give you a timeframe. Being for webgl or not isn't relevant. "Unity" disqualified this use case against anything that I mentioned, because the creators don't base their product off .NET 6 or anything that it is used for.

[solar anchor]

i dont understand 😄

"Unity" disqualified this use case against anything that I mentioned, because the creators don't base their product off .NET 6 or anything that it is used for.

[violet valve]

.NET 6 is a totally different product. Unity's C# backing isn't related at all. .NET and C# version are not the same thing.

[solar anchor]

ok I probably can't just build the vs project and put into the unity project?

[violet valve]

Unity uses a locked version of C# and provides it's own compiler, so it's on a different release schedule than most of what you can find on NuGeT.

[solar anchor]

hmm

[violet valve]

So in other words, other libraries might be compatible, but Unity has it's own microcosm so it's not guaranteed.

[limpid prairie]

Hey guys, how do I access the "Navigation" tab at the top via scripting?

It's a tab from Window > AI Navigation

[violet valve]

@solar anchor .NET "framework" is officially discontinued since Microsoft has adopted targeting multiple operating systems with the same C# code. Any reference to that in Unity is kinda outdated, but I understand where the confusion comes from. You might think that framework 3.5 and .NET 6 are the same product, but they aren't.

@solar anchor For a general idea, search up .net core vs .net framework and just assume that .net 5+ is "core". That should give you a good overview of what these branches mean.

[surreal vessel]

do you keep your settings centralized or not?

curious

could do a static Settings class or just use playerprefs everywhere directly

[violet valve]

I personally avoid saving stuff to registry if I can help it, which is what playerPrefs does. My minimum is to encode to json and store in a flat file.

[surreal vessel]

i see

[violet valve]

The issue is, it might not take up a lot of data, but I don't trust Unity to uninstall anything in registry. It kind of leaves a mark on any computer where someone runs your game, whereby saving JSON to a flat file leaves something that they can delete. It's also pretty easy to do in C#.

[surreal vessel]

yeah but a lot of apps do it and its not an issue imo

[violet valve]

You can absolutely be as shitty as the rest; I won't criticize that. You do you.

[jolly token]

There is no downside of abstracting playerprefs with your own setting class

[surreal vessel]

i was going to use PlayerPrefs everywhere where somethings influenced by a setting, but it doesnt have an onchanged event which is such a big flaw imo

[jolly token]

You can always swap implementation if you abstract settings.
If you use PlayerPrefs everywhere then you will pay technical debt when you have to modify or refactor them.

[surreal vessel]

yeah and also generally its probably a better idea to have actual variables instead of accessing things with string keys

[violet valve]

PlayerPrefs is intended as a storage destination, not a mechanism. It works well and is resistant to install/reinstall, but works via resources that the average PC user doesn't understand. It's not egregious if you use it, but if you're asking about reason for/against, you'll find plenty.

[solar anchor]

ok so can I make it work in unity or not??

😄

[violet valve]

Give it a shot and let us know. Without spending time investigating myself, I can't tell you any more.

You might be able to jerry-rig it, but that's an investigation task that takes time.

@solar anchor I hope I explained some of the concerns and potential difficulties clearly enough so you understand the scope of the question.

[solar anchor]

just creating a .dll from a vs lib projectis not the solution

[violet valve]

You have to consider C# version and a great deal of dependencies. I don't mean to stonewall you, but it's potentially complicated and you wouldn't know to what degree until you try.

[solar anchor]

hmm no it seems to difficult for me

maybe better to make the web app without unity 😄

[violet valve]

It could be difficult for me too, which is my point. I can't guarantee anything without trying for myself, but I know I might be in for a doozy if I did. That's the bottom line: the research isn't obvious, so whoever explores this is guaranteed dedicating time to research with no certain end.

@solar anchor In other words, I don't know and if you want me to try to figure it out, I have to do real work. That's my warning and honest take on this.

[solar anchor]

sounds good

[violet valve]

I wish I could connect the dots a bit more directly, but a solution isn't obvious. :_

[solar anchor]

hmm. I'm thinking about letting this wallet working over a server and let call the functions over unity api connection

and people identify/ login by metamask and then interact with the wallet functions on the server

but then the question: what is the best server config to have it secure and maybe decentralized

[violet valve]

I would implement this and then come back here with your configuration in tow. Information security is a trade and the interpretations are distinct and wide.

[solar anchor]

Implement what?

[violet valve]

Implement "the wallet server", then report here with your settings and we can maybe offer advice.

[solar anchor]

Ok thx.

[violet valve]

Context is a big help in determining the best approach to things. We don't necessarily know what you are using or what the best practices are, but we can assess and give impressions.

[candid shore]

Hey guys, My problem is im trying to spawn points in my game randomly at random postion but i dont want them to spawn to close to each other so im doing a do-while loop to check if these points are close to each other but i think i unintentially amde an infinite loop and idk how or why its happning.
Heres code:https://hatebin.com/onwhutoojq
(Just look at the Toclose Bool)

[sly grove]

kind of a #archived-code-general question, but it seems very possible/likely for your code to get into a state where it is not possible to generate a point that has not been chosen already or is not too close to another chosen point already. You don't have any guard against that or escape hatch for too many iterations

so you just end up in an infinite loop

[candid shore]

So what do i do?

[sly grove]

Add an escape hatch to your loops to prevent an infinite loop and attach the debugger to figure out how you're ending up in a loop and adjust your code to fix it.

[candid shore]

See

[candid shore]

what do you mean exactly?

like theres no points

bc the issue only happens when i want togenerate more than 1 point

[sly grove]

I'm not going to handhold you through debugging your code in #archived-code-advanced

[candid shore]

ok

sorry

cyalater

[kindred tusk]

Instead of doing a check, you could divide the world into squares and then place the points inside each square with a minimum space from the edge

That will guarantee that they're no closer than two of the edge paddings

But will give you a more uniform distribution

[raven raptor]

Yeah, it looks like the distribution process is somehow breaking the "worlds" rules. Then it never completes a success check & death spirals.

[regal olive]

hey

how do i deal with ramps when using rigidbody based movement

because my movement treats ramps like stairs

[compact fulcrum]

Been working on my own kinematic car collisions but I'm stuck; I've two methods to test collisions: Physics.CapsuleCheck (can take rotations into account but doesn't return the Collision info, only the Collider you collided with), the other is Physics.CapsuleCast, that returns the Collision but won't allow me to test a specific rotation. I need the normal of the collision to make object slide, but if I rotate it, it will eventually get inside the other object's collider and stop finding a collision. Any other alternative (SweepTest won't let me set the rotation either)?

[sly grove]

You can cast a capsule with any rotation with CapsuleCast

(the rotation of the capsule is defined by the two sphere centerpoints)

Also note that OverlapCapsule works just like CheckCapsule but returns more information about what you overlapped with

though it won't give you collision normals, only CapsuleCast will do that

[undone coral]

this looks nice

[compact fulcrum]

thanks! the rotation bug is the only thing I need to fix so I can move on; still can't get it right, but there must be an issue in my code (yet to give OverlapCapsule a try)

[undone coral]

what do you mean test a specific rotation

did praetor not address your question?

[compact fulcrum]

I'm still trying the alternatives, there may be issues with the values I pass; I want to make sure before I ask for help again 😄

[dapper nest]

Hey! I'm trying to switch from using LINQ orderby to using a SortedSet with a IComparer implementation, but even though in theory it should be the same, the results vary widely, so was hoping someone could maybe shed some light on it.

// First implementation of sorting by lowest value. This is for pathfinding
// and works exactly as expected.
HashSet<Vector2Int> pool = new HashSet<Vector2Int>();
var bestCell = pool
                .OrderBy(c => (c - start).sqrMagnitude + (end - c).sqrMagnitude)
                .First();

// Second implementation, which produces wildly different results, even though in my mind, the result should be the same. 
class CellComparer : IComparer<Vector2Int>
{
    public int Compare(Vector2Int x, Vector2Int y)
    {
        int first = (x - _start).sqrMagnitude + (_end - x).sqrMagnitude;
        int second = (y - _start).sqrMagnitude + (_end - y).sqrMagnitude;
        return first.CompareTo(second);
    }
}

SortedSet<Vector2Int> pool = new SortedSet<Vector2Int>(new CellComparer());
var bestCell = openList.First();

[jolly token]

Is it only typo that last line uses openList not pool?

Also can't tell how is _start and _end are assigned

[dapper nest]

both good questions!

using pool istead of openList because it is an assignment to optimize the script, so I am trying to stick to the original naming, which is pool. Though I agree it should be called openList.

As for the second one, both _start and _end is both private class variables that is set when the method for finding path is called.

The first implementation is using method parameters start and end directly, while I cache them in a private variable in order to access them through CellComparer

[jolly token]

The thing is the code you posted seems to be modified from the code that is running, so it is hard to tell if there is any bug or not

It'd be better if you post original code with paste site?

[dapper nest]

Not really. Outside of changing how to store the Cells, the actual code does not change at all. What is posted above is the only change, as the code for adding and removing from the set is the exact same. And like mentioned, the issue only arises with the second example

But I'll post the whole thing

https://gdl.space/hajesororo.cpp

The only changes is commented out.

[jolly token]

Thanks, maybe it's tiebreaker issue? How different the result is?

[dapper nest]

The thing is that I am not sure it boils down to something like that either, as it really just breaks the entire system. Consider the example here, where green is the current position, blue is the position to pathfind towards. It will then follow the red path drawn

Even if it came down to tiebreakers, there is no way this would be the result

And like mentioned, using the original LINQ works perfectly as expected

[jolly token]

Thing is SortedSet does not allow element with same priority
So if your Compare methods returns 0 for two different tiles, one will not be added

[dapper nest]

Ah. That might explain it.

[jolly token]

So you could try adding tiebreaker with tile position

[dapper nest]

When you say using tile position as tiebreaker, how would you go about that?

[abstract folio]

https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.sort?view=net-7.0#system-collections-generic-list-1-sort(system-comparison((-0))) If you can use a plain ol' List<T>... I like this first method.

[dapper nest]

Yes I could use a list, but the whole point is to optimise it, which a list would really not

[jolly token]

public int Compare(Vector2Int x, Vector2Int y)
{
    int first = (x - _start).sqrMagnitude + (_end - x).sqrMagnitude;
    int second = (y - _start).sqrMagnitude + (_end - y).sqrMagnitude;

    int comparison = first.CompareTo(second);
    if (comparison != 0)
        return comparison;

    comparison = x.x - y.x;
    if (comparison != 0)
        return comparison;

    return x.y - y.y;
}

Something like this for example.

[dapper nest]

Ahh I see what you mean. That might be exactly what i'm looking for!

[jolly token]

Also I would pass start and end to constructor of CellComparer than using static variables 😄

[dapper nest]

I was under the impression that the comparison had to be either -1, 0 or 1

[dapper nest]

Fair point. This was kind of just thrown together quickly for the sake of getting help. But thank you for the great assistance

[jolly token]

As long as the sign is consistent it will be fine, try and let us know how it went

[dapper nest]

I moved the changes into the already optimised version of the project, which seems to have completely fixed the problem. Thank you a lot for your time and expertise @jolly token !

[jolly token]

Nice, good luck with your project 😄

[dapper nest]

        material.renderQueue = -1;
    }```

I am trying to use this code I found to change the rendering mode of a material to fade and to opaque but I get this error:
> Render queue value outside of the allowed range (-1 - 2449) for selected Blend mode, resetting render queue to default
This is where the code is from: https://forum.unity.com/threads/change-rendering-mode-via-script.476437/
I have tried changing the renderQueue to a range of things but I don't really understand it.
PS: I am trying to fade out a model and fade it back in again, it fades out okay but doesn't fade back.

[undone coral]

hmm. why are you doing this

if you want to fade something out, you can
(1) tween its materials' alpha
that's it

you can't use C# overrides to turn any material, in a general way, into something that fades

[compact ingot]

seems like there is an issue with z-sorting and the object is supposed to render opaque while not fading

[undone coral]

hmm

[compact ingot]

i'd suggest alpha clip dithering

[undone coral]

is this Built In Render Pipeline Problems

Built-In / URP* problems

[compact ingot]

transparents don't sort right (by vertex) in any pipe

[undone coral]

i have had a good experience in hdrp dealing with alpha

in urp and built in, it seems like a colossal number of 3rd party materials have weird z write settings

which interact with each other, and then it's bandaid after bandaid

hdrp 3rd party materials are all really the same material in disguise

[compact ingot]

good to know, i've only ever had those z sorting issues 😄

[undone coral]

i'm not really sure though

lol

certainly when i'm working on other people's code

this is what i see. i select all the materials, the third party ones, i reset all these z write and blend mode and other settings to defaults, and the image doesn't change except all the alpha and sorting glitches go away

[compact ingot]

best way is the AAA way: just say no to (intersecting) transparency

[undone coral]

yes the code snippet shared above does make it seem like people have trauma related to URP and Built in materials' alpha

[cerulean scaffold]

Hi everyone, can the serializedVersion field in .meta files be set to anything, or could that lead to some problems?

I'm asking because I would like to not worry about that field when making changes to .meta files manually

[sage radish]

I think it's safe to assume it's used for something

[sly grove]

I actually don't see such a field in my meta files so 🤔

I see it only in prefab and scene files

[cerulean scaffold]

I see it in texture files aswell. Maybe it depends on the Unity version. I'm on 2022.2.

[cerulean scaffold]

I wonder what it's used for 🤔

[sly grove]

probably for when the serialization format of the class changes

[sage radish]

Yeah, for backwards compatibility

[leaden sandal]

You can, I am switching a mesh between rendering modes in order to remove the weird effects that appear when using fade on my model. But sometimes it needs to be on fade.

[undone coral]

well you can, but it won't work 100% of the time

[leaden sandal]

I know, but it's the only way.

[undone coral]

yeah if you imported asset store assets from an earlier version it would need to migrate somehow.

[undone coral]

i don't understand the issue yet

what are you trying to do?

[leaden sandal]

Change rendering mode of an object via script

[undone coral]

i mean what it eh big picture thing you are tryihng to do

[leaden sandal]

Tardis

[undone coral]

fade a 3d object in and out?

[leaden sandal]

Yes

[undone coral]

and what do you obsreve that goes wrong?

[leaden sandal]

But it must return to opaque

[undone coral]

what does that mean?

like what is the issue

[leaden sandal]

Rendering queue is not right

[undone coral]

i know, but what do you see that is wrong?

like what do you observe that goes wrong?

i'm not trying to be annoying

[leaden sandal]

It's completely invisible when running the code

[undone coral]

there's going to be a straightforward approach to this

i just have to understand what you are trying to do

fade an object in and out?

is that all?

surely you see people do that all the time

[leaden sandal]

Yeah then return it to opaque mode

My mesh's aren't basic boxes so when left on fade mode with no transparency it looks weird

[undone coral]

what materials are you using?

[leaden sandal]

Standard materials with smoothness off, specular highlights off and it's blue.

[undone coral]

okay

[leaden sandal]

And I'm doing it to multiple textures

[undone coral]

so you have a few options

i don't totally understand why you need to manipulate the material at all. you can make this material transparent, then tween the alpha when you need

using DOTween

and not do anytning else, and if it's really as standard as you say, everything will work

and you won't have to worry about anything

you haven't really said what the real issue is, like what hte visual gltich is or whatever you SEE or OBSERVE that is the problem

so don't get mad at me if i "don't understand"

because i've asked like 4 different ways

you don't ever have to switch it back to opaque

[leaden sandal]

I'm not mad at you at all I'm grateful that your trying to help

[undone coral]

okay okay

if you DO need to switch the material back to opaque, which again i don't 100% understand why you'd have to do that but i am so much more familiar with HDRP and URP and not built in which have fewer bugs overall with rendering

make two copies of the material

instead of modifying these settings

and don't touch z testing or blend modes or anything there

click reset, then set back up the color and textures, and change nothing else. and have two materials - one "transparent" and one "opaque" and reference it in your effect

it sounds like you observe a visual glitch when you leave your geometry at 1.0 alpha in transaprent material. is that correct?

[leaden sandal]

Yeah

[undone coral]

like another user said you can use dithered alpha cutout. but i think that's really a problem with all the other things you are changing

like just duplicaet this opaque material, click reset

then manipulate the alpha in the editor

with your object in the scene with the new, clean material assigned. do you see any glitches?

[leaden sandal]

No, when it's in opaque it looks normal.

[undone coral]

you just shouldn't be doing any of this enable and disable keyword stuff

okay

can you show me

can you create a new gray material

change it to transparent

put your model in your scene, and in the scene view, show it to me glitched

using a new material

then we can see what the underlying problem is

[leaden sandal]

I'm not at my PC right now. but I think just swapping between textures would work.

Materials*

[undone coral]

well don't say you did stuff that you didn't do

because i am telling you, you are doing something super screwy

your materials are messed up, and the C# code you posted is really messed up

it's a bunch of mistakes interacting with each other in a bad way

[leaden sandal]

There's nothing sepcial in the materials so I can just delete and restart them

And use alternating materials

[undone coral]

okay

that's good

[opaque cape]

I made a 2d grid array how do i remove the small ones?

[compact ingot]

Walk each pixel, if you find a white one, start a red flood fill and count the pixels it fills, if the flood fill count is < nSmall, do another flood fill from the end pixel, this time black, continue until done

[opaque cape]

Make sense, thank you.

[jade grotto]

Any way to limit an ICanvasRaycastFilter to just operate on the Graphic it's on, not children?

[jade grotto]

Looks like Image.alphaThreshold also affects it's children, doesn't seem right

[muted crane]

Use GetComponent<>()

So it will get the component only in the parent

[jade grotto]

This isn't something I'm fully in control of, in Graphic.Raycast it does 'graphic.GetComponents<ICanvasRaycastFilter>();' then in a while loop goes up the hierarchy doing the same, which is how RectMask2D is able to filter clicks on it's clipped children

Hello im having problems figuring out how to add a feature where if you press on a npc, the npc walks to the designated point

Like in a video, you can see when you press on an npc it walks to the stairs and some even go there them selfs

How do i do that is im using SpawnObject() and every npc has the same script so if in code it to travel to specific coordintes all npc clones go there

I need only the clone that i pressed to do that

What script do i need to use?

It was set to .NET Standard 2.1... Pretty sure .NET Framework is more up-to-date?

[jolly token]

No standard is more up to date

So your library should target .netstandard2.1

[warm forge]

This isnt the same script

[jolly token]

Yeah that’s not PauseManager

[undone coral]

this looks nice, did you draw it?

you are showing us a #archived-code-advanced game with #💻┃code-beginner programming skills

can you share a snippet of what you already have?

[clever urchin]

So I have a question to do with compute shaders and collision meshes.

I'm currently using the GPU to draw my map for performance reasons, this map is destructable. It's a 2D grid of tiles essentially however i'm having trouble generating a collision mesh for this

What is the best way for me to generate a collider from a 2D grid of points, could I do a bounding box search in the grid to get the perimeter of each collider and generate it that way some how?

[harsh matrix]

are you familiar with distance fields

[clever urchin]

No but they look very similar to what I want ha

[harsh matrix]

https://prideout.net/blog/distance_fields/

you can basically sample your space and give it a value, say <0 = ouside and > 0 inside

then jsut build a mesh connecting the sample points where it's 0

[clever urchin]

Oh neat, it looks like it can be parallelized too?

So I could just compute buffer calculate it, generate the points and make a mesh collider from connecting those points together?

[harsh matrix]

if you can be sure all 0 points have 0 neightbours, you can build a compute shader that checks its 8 neigbours

basically, your sample space needs to be somewhat continuous,

[clever urchin]

Ok I might be able to work around that

Since the terrain is destructible, i'm not sure how that would affect sampling. But I know the original setup will be fairly simple and can just modify the collision mesh on destruction or something

But yeah thanks so much for that, I appreciate it

[harsh matrix]

i think that deep rock galactic does somethign similar to this but 3d

[clever urchin]

That looks complicated asf lmaoo

[harsh matrix]

being destructible shouoldn't matter, as long as the system you use to generate the original map works, you just need to run the same code when you change the map right

[clever urchin]

Yeah, the map just might change a lot so I wonder if chunking it would be better performance

Guess I just need to play around

[harsh matrix]

yeah

worry about chunking later, get this system working on one chunk

don't preoptimize, you're working on a tricky problem

[clever urchin]

Yeah cheers

[harsh matrix]

hack the hell out of it until it works

have fun haha

[clever urchin]

Think like Terraria, except everything I can put on the GPU is going to be on the GPU

[harsh matrix]

i expect every pixel to be a voxel

[clever urchin]

Legit what it is lmao

Except 2D because 3D sucks :^)

[harsh matrix]

if you're working on computer shaders already, you can definitely do what your'e doing with 3d voxels too

[clever urchin]

Yeah, I think the jump isn't as big as I think it is. I just want to see how I go with 2D for the moment

Im a big fan of 2D games like terraria :)

[harsh matrix]

me too, lmao

i'm working on a 2d tile based rpg jsut to see how much tech i try to put into a low tech game

[clever urchin]

That sounds sick

[harsh matrix]

i am sick

i can't jsut

[clever urchin]

Lol

[harsh matrix]

not try something stupid complicated

i have a problem

it's ruining my life

[torpid plaza]

can someone help me with mathlerp

[clever urchin]

Yeah thats me with shaders, ever since discovering compute buffers and stuff like a year ago i've been trying to do everything in a shader

[harsh matrix]

hi

[torpid plaza]

when i crouch the player goes to 0.5 and then when i let go of control it goes back to 1

so i figure i can use mathlerp right

[harsh matrix]

you need to give more details

this is not really the chat for that kind of problem though

check out general or beginner

@torpid plaza where are you trying to use mathf.lerp

[torpid plaza]

if(Input.GetKeyDown(crouchKey))
{
transform.localScale = new Vector3(transform.localScale.x, crouchYScale, transform.localScale.z);
rb.AddForce(Vector3.down * 2f, ForceMode.Impulse);
}

    //stop crouch
    if(Input.GetKeyUp(crouchKey))
    {
        transform.localScale = new Vector3(transform.localScale.x, startYScale, transform.localScale.z);
    }

@harsh matrix

i figure i was going to add it on the if statement for stopping the crouch

but i probabaly need to do it on both

[harsh matrix]

where would you use the lerp?

[torpid plaza]

on both if statements?

[harsh matrix]

can you show me how you would want to use it

liek show an example

[torpid plaza]

if(Input.GetKeyDown(crouchKey))
{
transform.localScale = new Vector3(transform.localScale.x, crouchYScale, transform.localScale.z);
rb.AddForce(Vector3.down * 2f, ForceMode.Impulse); ???????????= Mathf.Lerp(startYscale, 2, crouchYScale);
}

    //stop crouch
    if(Input.GetKeyUp(crouchKey))
    {
        transform.localScale = new Vector3(transform.localScale.x, startYScale, transform.localScale.z);          = Mathf.Lerp(startYscale, 2, crouchYScale);
    }

hold on

@harsh matrix something like that i guess but i don't know what variable to use to set it to

im not even sure if mathlerp would work someone suggested it

[harsh matrix]

why do you want to use lerp here?? the code ytou have looks fine

[torpid plaza]

because when i crouch it just snaps back to 1 in a instant

itt's too snappy

[harsh matrix]

oh you wantlike a smooth change?

[torpid plaza]

yeah

[harsh matrix]

ok you need to use a coroutine

are you familiar with those

[torpid plaza]

no

[harsh matrix]

ok can I DM you

[torpid plaza]

yeah

[quiet bolt]

You could also use DoTween

So you can just make a one-liner that will smoothly transition over time

[real blaze]

or AnimFlex :p (just transform.AnimPositionTo(end, duration) or use Tweener.Tween(getter, setter, endValue, duration, delay, ease) if you feel like u wanna go deeper! )
https://github.com/somedeveloper00/animflex
free and open source. and you'll get 40% performance boost too 😁

anyways

I have a problem with a manual physics scene having to iterate a dozen times per fixed update. issue is that the onCollisionEnter doesn't work as expected

I'm doing custom bounce mechanics in the onCollisionEnter, and when I do the physicsScene.Simulate() a dozen times in fixed update, the results will actually be different. I assume it's because some transformation resolving phase is being ignored when we do the Simulate more than once in a row, right?
this seems like a common problem but I couldn't find anywhere for a solution. does anyone have any suggestion?

[lament salmon]

I used to deal with a similiar issue... This might help:
https://docs.unity3d.com/ScriptReference/Physics.SyncTransforms.html

[real blaze]

hmm, when I'm calling ps.Simulate() , I was actually very worried about these probs, so only modified physics stuff in physic events, and transform stuff in , well, other events. so the sync function wouldn't really help me.

• but I totally didn't know it even existed! thanks. seems pretty useful

I solved it by calling FixedUpdates manually before doing ps.Simulate(), like Unity's own physics event timeline

to get all the required FixedUpdates, I created a global SO that holds a list of delegate void FixedUpdate()s and then each script will subscribe and unsubscribe to/from it themselves

and that fixed my problem.

tldr: make sure to manually call all necessary FixedUpdates before each call to physicsScene.Simulate()

[tiny ocean]

How would I specify a ToString formatter in a com.unity.localization Smart String?
I'd like to use the N0 specifier to emulate a ceil()
My smart string looks like this
{Cookies:plural:1 Cookie|{} Cookies}

[hybrid prism]

Hi
How can I debug ILPostProcessor inherited class (codegen after compilation)?

[muted widget]

https://gdl.space/nujatufago.cs

Any ways to speed this up a bit? I removed Recalculating Tangents because I am not using normal maps here. I don't typically work with meshes, so the more I can learn the better. Sorry, code was too large to send here 😛

[flint oxide]

I'm trying to burst some code via jobs and is unable to use System.Guid.ToString() in debug messages... any ideas?

[sly grove]

I think string itself is a managed reference type and can't be used in jobs right?

[flint oxide]

yeah so it seems like I need an alternative way to see the bytes in the Guid to print it out, mmm

[sly grove]

Can you just run the code without burst/jobs to debug?

I think that's usually how I did it

[flint oxide]

yeah but then it's hard to debug parallel problems 😦

[sly grove]

It's always hard to debug parallel problems 😉

[misty glade]

I ended up going to SO & prefab route and it's not bad. The end consumption is two lines of code (get a prefab by enum, then awake it - it'll destroy itself with a coroutine that sniffs the particle system duration).

Getting the actual effects to show up in the UI is no problem. 🙂 FWIW I'm using the mob-sakai particle effect library since it's.. really nice to use with UGUI based applications without fiddling with cameras and z-ordering endlessly

[lunar jackal]

any idea how I can change the background image of an IMGUIContainer in my programming? The docs stated nothing usefull, and in the forum I found no such topics

[compact fulcrum]

@undone coral @sly grove just a little update on the issue I had: gave up on checking collisions on my own when I found out about ForceMode.VelocityChange. Managed to make it quick, responsive and still collides properly 👍

[sly grove]

ah - yeah working within the system is good

[undone coral]

that looks nice

how is it controlled? joysticks?

[compact fulcrum]

atm I'm using the keyboard keys, but I lerp the rotation of the wheels

[undone coral]

how do you feel about making it work with touch?

or a single mouse

also, did you make the vehicle model?

[compact fulcrum]

nope, I got it on from some asset I was testing; ended up not using the code but kept the model so I can test it w/ it

[compact fulcrum]

It should work, I use a simple -1 to 1 range and I should be able to replicate what I had in other engine

And in my tests there, it worked nicely with touch controls

[undone coral]

when i say with touch, i mean not with virtual joysticks

it would be an interesting problem to solve: how do you do drifting with touch, and no virtual joystick

in my experience people try to draw a doughnut with their finger and they expect the car to do a doughnut

which is very very interesting and sort of hard to do

[compact fulcrum]

oh that I haven't tried, would have to take a look at the games that do it

[potent shoal]

I'm really struggling with this. I have no clue how to get System.Security.Cryptography.Cng working in unity.

I have added System.Security.Cryptography.Cng, as well as System.Security.Cryptography to my assets folder.

[sly grove]

Does Unity not include System.Security automatically?

[potent shoal]

Apparently not.

[undone coral]

do you have a backbone / razer kishi for your phone?

[potent shoal]

What version of the .net framework does unity use?

[undone coral]

it uses netstandard 2.1 and supports many net framework 4.7.x apis

however its implementation of netstandard 2.1 is incomplete

what is your goal?

[potent shoal]

I have a library using ECDiffieHellmanCng, which is a member of System.Security.Cryptography. I'm finding the versions are inconstant.

[undone coral]

okay. first step is to disable version verification in player settings, if that is all the issue is

that's what i assume you mean by "versions are inconstant [inconsistent]"

[potent shoal]

yes

[undone coral]

okay

so you'll wanna start by checking that box off

here's the big obstacle with what you want to do: if there isn't a managed implementation of the cryptography api you want to use, and it's not specifically supported by unity, you should only expect copying and pasting DLLs from nuget or wherever with the cryptography implementation to work on windows

there don't exist managed implementations of everything and there never will. what library are you trying to use? have you been trying to get iota to work?

is that what you were doing earlier?

[potent shoal]

I'm just trying to setup encryption for my game client and game server.

[undone coral]

or why is this cropping up? like what library are you trying to use

okay

you're trying to encrypt a TCP connection?

[potent shoal]

Yes, and it works fine outside of unity, which is where my master server resides.

My class is this

https://hastebin.com/heherozupo.csharp

[undone coral]

okay, lemme ask you this first. do you think there is a standard way to encrypt a TCP connection?

[potent shoal]

I am not trying to encrypt the connection, but rather certain data going across the connection.

[undone coral]

hmm

what is the idea?

for anticheat?

what is the threat you are trying to prevent

[potent shoal]

It handles authentication for players, authentication for game servers, server spawners and also token authentication.

[undone coral]

your approach is dead in the water because a bunch of this stuff won't work, ever, in unity's .net environment, so let's at least talk about what makes sense

without getting mad or telling me this "already works"

which you haven't done yet and i appreciate

so what is the threat

i'm going to show you that there's no difference between encrypting the connection and encrypting the data going across the connection, for all your threats

so we can save the time

[potent shoal]

I see

[undone coral]

you should be using an SSL stream with tcp client, i.e., using TLS, if you want to make an encrypted TCP connection. you can also use http/2 or http/3, which supports bidirectional streams and will give you enterprise-grade security out of the box

https://stackoverflow.com/questions/39304612/c-sharp-ssl-tls-with-socket-tcp

sslstream is supported by unity and you should choose tls3 or whatever is the latest version when you choose a protocol

[undone coral]

for this stuff you probably want to use http...

if you have a realtime game, you can use websockets, which are very low overhead compared to raw tcp. if you need UDP connections, there is a ton of work if you ever want to have more than 1 server

[potent shoal]

I see

[undone coral]

i mean if you are trying to do this yourself

if you use a vendor it's way easier

like photon or whatever

[potent shoal]

My master server is setup in the way that makes the most sense to me. I built an entire framework to spawn and manage my game servers. I found that I preferred to use a TCP based connection, rather than HTTP for my master server.

[undone coral]

https://forum.unity.com/threads/what-are-the-pros-and-cons-of-available-network-solutions-assets.609088/#post-4251394

here's one perspective

yeah really hard to say without knowing what game you're making

which i would be happy to talk about

i personally use grpc, but it is extremely arcane to get that to work in unity

and it's low yield for anything but the most complex games

[potent shoal]

To elaborate a little. I have a game server which uses FishNet framework. However, I still need to interface the client and game server to a master server, and for this I've chosen to take my own approach and built my own network transport.

My game is fast paced, and uses client server prediction, something that took me years to understand, and my solution requires that I use UDP for that purpose.

As far as my master server connections, these all use TCP.

[undone coral]

okay

well

i don't doubt you can write all this stuff

you should use TLS

if you want to encrypt a TCP connection

on your backend server, you can similarly use TLS as a standard

alternatively, you can use a TLS proxy (an SSL terminator feature in something like nginx or traefik) on the backend

so that your server does not have to be aware of certificates or anything like that

you can use a self issued certificate, naturally, it's not a website
