[frank peak]

basically you gotta find the ultimate meta

[soft hawk]

Oh I've watched all the stuff with SC2, was very revealing about how these NNs are working

[frank peak]

that the bot can exploit lmao

[soft hawk]

and training

[undone coral]

yeah it's scientifically very interesting

but there's a really good reason it's starcraft and not hearthstone

[soft hawk]

But I think they've got a pretty robust SC2 ai at that point?

[undone coral]

same with DOTA 2

[soft hawk]

it just takes like milliions of training hours

[undone coral]

i think they ran a trial of the bot playing against real humans in SC2 matchmaking

on the public matchmaking

but there were too many flaws with that? i don't remember what happened

DOTA 2 they let people play against the bot and normals defeated it in like 30m

[soft hawk]

Last I heard it was pretty successful at a fairly high ELO

above 2k

[undone coral]

yeah well there's a reason people kind of stopped playing starcraft

as a competitive experience

[soft hawk]

Dota is actually much more complex

[undone coral]

DOTA has the same mechanics where a little bit of excess dexterity at the right time wins the whole game

like i said, why not a hearthstone bot?

[soft hawk]

the path to victory in a MOBA is much more complicated than the path to victory in Starcraft

[undone coral]

dexterity has no role in the game, is the answer

[soft hawk]

Vastly different hehe

[undone coral]

even the poker bot that the CMU team made... the experts felt the bot fatigued them out

[soft hawk]

because it played cautious? I haven't seen anything about that one

[undone coral]

you can read about the circumstances of that experiment, and the bot started to rack up its biggest wins after an unrealistically long amount of multiple-hands play

it doesn't get tired

[soft hawk]

12ms to go 4 deep on a 5x5

5x5 is too short though, way to easy to lose with an unlucky run of blocks

even w/ a very short queue

[undone coral]

maybe make a lucky run of blocks

all the time

[soft hawk]

well the idea is that a queue of x length must contain a breaker-block of each color

so a shorter queue is a "lucky"er queue

[undone coral]

the essential ingredient of alphago/alphazero is that a chain of many transitions in go corresponded to something that could be learned by a deep network

because Go looks like convolutions on matrices

https://www.deepmind.com/blog/alphago-zero-starting-from-scratch this also reduced its resource usage, according to them

how true that is i don't know

[unkempt nova]

It decimated almost everyone and they had to nerf it

Even after the nerf it could go toe to toe with the best players

[undone coral]

but also that game had fewer than 30k online players, even then

[soft hawk]

Well they say it plays on bnet at grandmaster level in open play

[unkempt nova]

Don't understand what that has to do with anything, but I only skimmed the convo

[undone coral]

i suppose an FPS bot that aimed perrectly would also destroy players

ol

i'm trying to emphasize that the starcraft bot had a dexterity problem hidden inside of it

i mean, i don't know how it was so hidden, it is obvious to everyone

[unkempt nova]

What kind of dexterity problem?

It had unlimited actions per minute, inhuman, you mean that? They nerfed that to be more human

[undone coral]

and they managed to convince the public that limiting APM was sufficient to limit the impact of the dexterity problem, and i'm saying it did not at all

the apm doesn't matter

it just needed excess dexterity compared to its opponent for a very short period of time

you're part of that public

[unkempt nova]

Oh you mean like, individual unit selection and stuff?

Yeah that was way over the top

[undone coral]

if you watch the real games, it only needed to portal 1 extra stalker

which a human could certainly do too, but the computer always correctly portals the stalkers

starcraft is, a big battle that determines who won

which is cool, that's a good setup for a game

the dexterity in that battle plays the biggest role in determining the winner

[unkempt nova]

One thing it used to be able to do, still can to an extent, is superhuman micro. It doesn't make mistakes like you mentioned, so selecting a single zergling in a swarm is no big deal. It can micro a swarm of them to have single zerglings take tank hits

[undone coral]

since the units with the greatest value have that value tied up in dexterity

right

exactly

[soft hawk]

The difference being that no only does the AI execute dexterous tasks to perfection, but it ALSO doesn't waste any actions

[frank peak]

is # of lines of code a useful metric in any sense?

[unkempt nova]

Not usually

[frank peak]

like saying "game X is Y amount of lines of code yada yada"

[soft hawk]

Only as a sort of general approximation of the time commitment, maybe

[undone coral]

i don't play competitive starcraft though, i will say stuff that doesn't make sense to a competitive player

[gentle topaz]

I definitely don't think dexterity plays the largest role in Starcraft

[undone coral]

but because of different language, not because we disagree

[unkempt nova]

Depends on who wrote those lines. A noob can make something 10k lines easily. Someone who knows what they're doing can reduce that massively

[gentle topaz]

A dumb AI with crazy micro will not win. It actually executes proper scouting, builds, and timings in addition to the good micro

[undone coral]

it is the proximate reason games are won or lost at the highest level

[frank peak]

thats fair. my comparison was hearing that dwarf fortress was 700 000 lines of code (as of a few years ago, maybe its diff now) and that seemed like... alot lol

[unkempt nova]

Largest, no. But it's a part of micro, so I get that it's kinda big

[unkempt nova]

It is and DF is kinda huge, Toady knows what he's doing I figure

[undone coral]

which if you think about what a deep neural network does, it's going to find the shortest path to the biggest reward and optimize the shit out of it

[frank peak]

agreed, hes harvard trained to which is pretty intense. not that their particularly known for CS but still.

[soft hawk]

It's a lot but like i said, that represents a HUGE, MASSIVE, almost INHUMAN amount of time on the dev's parts. They've been working on it for decades(?) at this point

[undone coral]

the APM constraint was window dressing to sell the project

[unkempt nova]

I've been playing it since like 2006 and it had been around a while before

[soft hawk]

Ya I remember reading about it in the early aughts

[frank peak]

i've been playing it since 2013 or 2012, its crazy how much has changed since then even

boat murdered lol (early community fort)

[soft hawk]

They haven't posted anything new on alphastar since 2019 😦

I guess if its beating everyone what's left to say

[frank peak]

i wish toady would go into more depth on his algorithms and stuff like how he implemented a* with mulitple z levels.

but he does his best in the future of the fortress posts

[gentle topaz]

Depends. I have watched many, many professional games of Starcraft and I feel like it is smaller trends unrelated to micro. You hardly ever see the top players mess up their micro. It's more like, a Zerg player made the decision to spend tons of resources on repeatedly attacking, but they keep attacking into an entrenched position, and now they are down many thousands of minerals in gas on their side of the map. The game gets long, and they run out of resources. Or, a Terran might choose to take air superiority but then get overrun by repeated Zergling runbys and have a difficult time tech switching with the constant harass. A protoss might fail a cheese because they got randomly scouted and eventually lose the game because they are behind

I don't think their AI could actually beat the TOP top players

It's less about the micro, and more about mindgames and army composition at the highest level

[soft hawk]

I think I will give unity ml-agents a crack and if it proves deficient I could rewrite things in pure c#.

[undone coral]

if the human player had excess dexterity at the right time, they'd win regardless of the strategic mistakes

this is true in DOTA and League of Legends too

i personally don't like these games

i find them stressful and not fun, and everyone i know who plays league is permanently soured against all other PvP games

[gentle topaz]

I don't think this is true of either of the other two games you mentioned either

A functional team aiming to win would beat dexterous players

[undone coral]

there are hardly any bots of strategy games.

the best evidence for how important dexterity is in starcraft is the fact that some people somewhere figured out how to get a spam* detection technology to play it well

[soft hawk]

Yea I think it's very deceptive to think that human dexterity is in any way similar to AI dexterity

[undone coral]

this is coming from the perspective of someone who has written these bots

[soft hawk]

There is a gulf between human dexterity and perfect execution

[undone coral]

and @soft hawk now has the perspective of having written a heuristic bot - what is the "game" hiding inside there, so to speak

it sounds like in puzzle fighter it's about setting yourself up to use the queue best

which maybe cheating (knowing the queue) has an outsize impact on that

it's not impossible to write a heuristic bot that handles not knowing the queue

[soft hawk]

Setting up combos is the key to high level play, yes. That's why my bot has to cheat. I didn't really see another way to do it

[undone coral]

it's hard though

[soft hawk]

Yea and I'm not sure how good it could be. It's very good right now even limited to 100ms, it can play indefinitely

But 100ms on this pc and 100ms on my phone are very different things 🙂

[unkempt nova]

Serral ended up winning I think after a few attempts

https://www.reddit.com/r/starcraft/comments/dqtpyf/serial_played_5_games_vs_alphastar_at_blizzcon/

Considered the GOAT, except maybe Maru

[gentle topaz]

Serral has improved quite a bit in the last 2 years, I didn't know they had actually done runs of these matchups though. I'm late to the party

[soft hawk]

Yea I think the last iteration of AlphaStar was very capable

[unkempt nova]

He went 0-3 against the toss agent lol

[frank peak]

if im spending full time developing something should i care about optimization off the bat, and if i don't, am i just adding technical debt (ie more time down the line fixing quick n dirty code) lol?

[gray pulsar]

you're probably going to rewrite large portions of your code multiple times as you figure out how it should be structured. And you don't know what parts of your code are going to be important to optimize from the beginning. Focus on optimization once stuff has settled into place, otherwise you'll just be wasting your time.

Some people make prototypes in a totally different language/engine than their final game will be to force themselves to throw everything away at some point once they have the design figured out.

[soft hawk]

I've rewritten this puzzle fighter clone 3 times at this point, the first iteration was a mess

[gray pulsar]

But also, don't do stupid things. If you can choose an approach that is more optimized for 10% more effort, go for that. But don't do 100% more effort to optimize it until you're confident that effort will pay off.

[sly grove]

resizing the game window in WebGL is something that needs to be done on the Javascript/HTML/website side, it's not really under Unity's control.

[inland delta]

https://docs.unity3d.com/2021.2/Documentation/Manual/webgl-canvas-size.html

[undone coral]

does the bot mass stalkers?

[stuck onyx]

Regardig the docs:
https://docs.unity3d.com/ScriptReference/Physics.BoxCast.html
the parameter halfExtents is a vector3 with HALF the size of the boxcast in each dimension...
And the example says:

 m_HitDetect = Physics.BoxCast(center, transform.localScale, transform.forward, out m_Hit, transform.rotation, m_MaxDistance);```

But in the draw gizmo example we see in the same page they do:
```c     
Gizmos.DrawWireCube(transform.position + transform.forward * dist, transform.localScale);```

So my question...  isn't the boxCast or the Gizmo draw missing a division by 2?

the boxcast expects half of the size... but then the Gizmo is drawing the full size

does it make sense?

is the example not accurate?

to my understanding the Gizmo would be drawing a box twice as big as the BoxCast actually is casting

[unkempt nova]

I don't think it massed them, but its stalker micro was insane

[undone coral]

what would a more strategic starcraft look like? Civ V is probably a good candidate

it's not balanced for multiplayer though

really hard to say what turn based games people play besides CCGs

with interesting multiplayer

[frank peak]

what about crusader kings 3?

that game is hella strategic in terms of political decisions

theres gotta be a bot meta

and its current AI sucks ass ngl, could use work (its a terrible ally in wars, for instance)

[undone coral]

that's a good one

[fallen halo]

My enemy game object has a child game object which is a trigger collider for an attackbox. This child game object also has a script that propagates the OnTriggerEnter2d call to the parent object. I want my enemy to have two kinds of attacks, a light attack and a heavy attack.
I am currently using the trigger attackbox for the light attack. In the light attack animation i am turning the trigger collider on and off.

Now for the second attack i can easily create another child object with another trigger collider and script.

But let's say i want to use the same child object for the two kinds of attack. Even though the two kinds of attack has different animation and different attackbox sizes, i can easily use the animation record option to change the attackbox size and position.

But inside the code where i call the TakeDamage(parameters) function of the player game object, how do the enemy know whether it should send the light attack parameter or the heavy attack parameter

[half palm]

Even a "simple" game like civ has terrible bots

It would take A LOT of processor time to train a decent bot on 4X games

[soft hawk]

So if my GameState is this:

public struct BlockParams
{
    public BlockType BlockType;
    public int ColorIndex;
}

public enum BlockType
{
    Empty,
    Basic,
    Execute,
    MegaBlock
}``` Can I just pass GameState directly to ml-agents CollectObservations() or is there an additional step I need to do for the BlockType enum?

hmm it doesn't like multidimensional array

[fresh salmon]

Don't cross post

[quasi granite]

Okay, so i am importing a more efficient matric multiplication library and it gave me a Unity Error as soon as I imported to library. It told me to turn off 'Use Deterministic Compilation' in Player settings
I did, and everything works fine, but I dont even know what deterministic compilation is, much less know if its bad or not for this to run.

[unkempt nova]

https://unity.com/releases/2020-2/programmer-tools#:~:text=Unity 2020.2 offers a “-deterministic,compiling scripts for the Editor.

Unity 2020.2 offers a “-deterministic” compilation option when compiling C# scripts. This option lets you avoid unnecessary recompiling of assembly definition (.asmdef) references if the public metadata for the assembly does not change when compiling scripts for the Editor.

I think basically it only recompiles assemblies that actually changed. Not sure why that'd cause an error

[quasi granite]

This is the matrix library https://www.codeproject.com/Articles/5835/DotNetMatrix-Simple-Matrix-Library-for-NET
and the error code it gave is attached, here is the code that is erroring.
https://hastepaste.com/view/SsKgl7
As well, The files have csProj files. Attached is a screenshot.

Ahh, this project uses another assembly file inside of it. Will that cause issues?

Ima just try it, lmao

[undone coral]

remove assemblyinfo.cs

and create an asmdef file

change the framework to netstandard2.0 and retrieve the project's referenced DLLs using dotnet publish

i should write a tutorial on this

[thin merlin]

So, I'm using the new input system, and storing the left stick's x and y position to variables:

        currentUp = gamepad.leftStick.ReadValue().y;
        currentRight = gamepad.leftStick.ReadValue().x;

And when I push the stick up, not to either side ...

What's going on here?

I'd think Current Right should be 0 or at least close.

[hollow garden]

probably floating point imprecision or smtn

cause that's like 0.00001525879

[thin merlin]

guess I'll make a check that if it's under, maybe 0.001 or something, it'll go to 0. My game doesn't need that precise analog input anyway.

[unkempt nova]

That might be the deadzone or something?

Joysticks often don't output zero, so there's a deadzone, or a "close enough" value that it sets it to zero when it gets there iirc

Might be able to change/increase that in input settings

[thin merlin]

yeah, cuz right now down is being treated as also holding right, and that's not what we want XP

this is what I see

[unkempt nova]

Deadzone seems ok to me, not sure

[sly grove]

When are you running this

[thin merlin]

basically at the beginning of Update.

[thin mesa]

that is close to 0

[thin merlin]

Fixed it by adding additional code that functions as a pseudo-deadzone, avoiding floats in a range of (currently) 0.00002, changeable if needed

[thin merlin]

the code considered anything above 0 for that axis to be "holding right". Like I said tho, I added my own deadzone code to fix that.

        if (currentUp < deadzone && currentUp > 0 || currentUp > -deadzone && currentUp < 0)
        {
            currentUp = 0f;
        }
        if (currentRight < deadzone && currentRight > 0 || currentRight > -deadzone && currentRight < 0)
        {
            currentRight = 0f;
        }```

tho if there's a way to shorten the lines I'd like to know

[thin mesa]

i would change the other code so that it works in a way that effectively 0 doesn't break everything

[thin merlin]

it's technically not needed with this fix, but I might end up reworking it anyway if I decide to make variable movement speeds based on stick tilt

which I'm honestly tempted to do.

[thin mesa]

it sounds like you have shit movement code tbh. you haven't actually shown it, but it sounds like you are changing bools which determine what direction you are moving rather than something sane like normalizing the input vector and just using that directly

[thin merlin]

I don't know about "normalizing the input vector" (or if I do then I don't realize that's the term for it), but the reason I save it to a variable is because that code is in an input script, and passes the input variables to the controller script. I do it this way to account for stick taps and macros, like Tap Jump, without needing to clutter up the controller script.

that, and the input script is so the player can control the character, and would be replaced with an AI that uses the same inputs when the character is controlled by a CPU. (yes this is a fighting game)

[thin mesa]

sounds like #archived-code-advanced may not be the place for you then. But you have a vector returned by gamepad.leftStick.ReadValue() you can store that, normalize it so that it has a length of 1 and it will be a direction which you can use to determine the direction of movement

[thin merlin]

ahhhh

well, I already do use a current speed that is always positive relative to the direction the player is facing (left or right) and negative in the opposite direction. So I did account for that already. This isn't my first rodeo with 2D, after all.

[thin mesa]

you will only need a single speed variable that you multiply your direction by, the direction handles positive/negative so you don't have to

[thin merlin]

@thin mesa Here's a very stripped-down version of my movement code in the controller:

... let me get pastebin up

https://pastebin.com/YundyFYc

That code only focuses on the horizontal movement, not the vertical or anything else

[thin mesa]

that's horrifying

[thin merlin]

It works, but if it can be shortened that would help

[thin mesa]

you're not even moving it in a physics friendly way either so if you expect colliders to work correctly you're gonna have to change how you move anyway

[thin merlin]

I'm not using Unity's physics for this project

[thin mesa]

okay then how are you restricting movement so that the object does not pass through objects it shouldn't? there doesn't seem to be any indication you are doing so in the code you showed

[thin merlin]

ground doesn't need collision for my purposes since there's no other level geometry, so I just have a value for what y float should be considered "ground"

and since it's a fighting game, I just set a hard limit on how far the players can move from the center of the arena. That's done with a Mathf.clamp that was removed in the pastebin for length's sake

the only thing I'll really need to figure out in terms of "solid" collisions is pushing players away from each other if they're too close, but that can be done with raycasts apparently.

Since I don't need to worry about level geometry for this game, I can just hard clamp the player's position so they don't go under the ground or outside the "walls".

[misty crescent]

private IEnumerator MyCoroutine()
{
    yield return new WaitForSeconds(300);
    
    // do something

    StartCoroutine(MyCoroutine());
}

private IEnumerator MyLoop()
{
   while(true)
   {
      yield return new WaitForSeconds(300);

      // do something
   }
}

What's a better solution?

[frank peak]

rather then waiting for 5 minutes with a coroutine? hmm one coroutine over 5 mins isn't so bad tbh

or two or w/e

[misty crescent]

What?

@frank peak no no, I just want a piece of code to run every once every 5 minutes. Is it better to have the co-routine run in a while loop for that or start another coroutine after the first 5 mins are up?

[frank peak]

oh derp

maybe start another couroutine, cuz the while loop is gonna call continously

as fast as possible basically lol

[misty crescent]

Yes but I read somewhere that's not how it works

[frank peak]

huh interesting

[misty crescent]

because WaitForSeconds() doesn't let anything happen for that period of time, even if in a while loop

[frank peak]

oo

well then i don't really see a difference then

[pale wave]

Can anyone help the badguys in my game attack me. (Im not good at coding so Ill need alot of help)

[sly grove]

The bottom one

[undone coral]

if you want to run something every five minutes, start a coroutine of the form

IEnumerator MyRepeatingAction() {
 while (true) {
  yield return new WaitForSeconds(5 * 60f);
  // do actions
 }
}

note you can cancel a coroutine gracefully using StopCoroutine() but disabling the script it is declared in does not stop it

if the coroutine is cancelled (by using StopCoroutine or destroying/deactivating the game object containing the coroutine) while waiting, it will not perform the action. if the coroutine is cancelled at any other time, it will have finished executing the action that frame or nothing will happen.

i do not believe it is possible to cancel a coroutine using StopCoroutine and then still observe it execute code after a yield

[carmine ermine]

i would add an extra if check after the yield return

what you would check depends on your game, but generally only if that condition is met, then you actually do the actions

although i might not be understanding exactly what you are trying to achieve

[green river]

Comparing against System.DateTime.UtcNow is how I go about it. I have enough times things tho that I have a scheduler and it knows the “next timer” to care about. Polling for one time is no big deal. Polling for 100 is.

Personally I’ve been burned too many times by coroutines

[final kindle]

I have a weird setup where my unity project is a little widget that sits on my computer, and I tab in and out of it with hotkeys to send it inputs. This all works fine, except I have to stay tabbed into it for a little bit to make sure it registers the sent inputs properly. This becomes a problem if I need to send inputs repeatidly, since I can't just repeat the press without it overlapping the last one and going funny. How can I make it poll inputs quicker? I've seen mentioned that you could use DLL's to check the input buffer but I have no idea how you'd go about that.

[raw schooner]

Is it possible to build Unity from source at all?

[hallow cove]

ok so I have a problem where I need to dynamically downcast an object variable-

it returns an error

[raw schooner]

Man that's unlucky

[hallow cove]

I could use a switch statement but that would mean having to do it for the hundreds of nodes I will create

[tribal pivot]

Care to mention what error?

[hallow cove]

I fixed it it's fine

I had to convet object to a variant of another abstract script

I just saved the type as a string and then got it that way

[undone coral]

it sounds like your FPS is low, or you're checking inputs in a fixed update

[final kindle]

Neither of them. Unity just does not play nice with tabbing out so I have to really make sure to give it it's time first.

[undone coral]

hmm

there is a checkbox for Input System that allows you to listen to all events even when backgrounded

maybe you need that

it's in the project settings

it's something about focus, and something about background

it's two dropdowns

in my experience applications configured this way respond to events correctly with the most generous settings in those dropdowns

[final kindle]

I do have it set to run in background, but not listening to input. I could maybe do that, if I put the keys used to something I'd never press otherwise like F13 through to F24. Not ideal though.

[undone coral]

you can always check if the application is focused

it's really odd you should "lose" some events in the beginning

something else is going on

[final kindle]

This is the kind of thing I have absolutey no idea how to debug, if I can at all. It'd be great if I could so I didn't have to do things like wait for the splash screen to finish before tabbing out to not break all callbacks (awake, update, etc).

[undone coral]

splash screen?

[final kindle]

The Made with Unity thing before everything runs.

[undone coral]

so wait what is your exact issue

you alt tab into something

and it doesn't respond to events

have it respond while in the background

change that and just see what happens

[final kindle]

I alt tab in, press a key, alt tab out, and it doesn't register the key press unless I wait to tab out. I'm doing this via autohotkey so this happens very quickly.

[undone coral]

autohotkey...

what is this application?

what is the idea

[final kindle]

It's software to make your own hotkeys to do extra things with your keyboard and PC applications. So for example, I've bound Alt + Ctrl + Shift + J to directly activate the unity window (what alt tabbing does but directly telling windows the one to activate), send it the Delete key, then tab back out to whatever the last active window was.

[undone coral]

what does your* application do?

what is its idea?

[final kindle]

Oh. It's a productivity clock. So it tracks my time utilised and wasted, averages them, and shows me if I've been getting better or worse at utilising time for work.

[undone coral]

got it

i think you should listen for all events

even in the background

for debugging purposes, draw a rectangle every frame if and only if the game is in focus

and see what that is telling you

also, if this is windows, try switching your graphics engine between opengl core, directx11, directx12 and vulkan...

there is sometimes a subtle thing going on with rendering the thumbnail in the alt tab window

directx has a dedicated approach to doing that

disabling it by switching away from (or enabling it by switching to) directx as your graphics may resolve it

[final kindle]

I wouldn't have thought of that. I'll try that when I get the chance, thanks. If not, I might do the background keypresses with some obscure keys so there's no conflicts.

[undone coral]

you can check if ithe application is in focus in an input processor

or whatever

start just for the diagnoses

[final kindle]

Oh ye, right. Also worth mentioning, I'm currently just using the old input system. Since this was meant to be a simple prototype thing I didn't bother and I didn't think these bugs were related, but that's something I could try too.

[undone coral]

hmm... use input system

Input is

Input is #archived-code-general or lower

Not really unity specific, but does anyone know how to make the nuget package manager in Visual Studio run faster? Using nuget packages with unity is awful because of how slow the manager is.

[undone coral]

use the dotnet cli for package management

[quartz stratus]

Is it possible to move a package (TextMesh Pro, in this case) out of the Packages folder into the Assets folder so I can directly modify the scripts? For context, I'm not trying to get clever and mod any packages, just want to add some log messages to debug an issue.

[undone coral]

copy the package's directory from Library/PackageCache to your Packages/ directory

[quartz stratus]

Thanks, that worked great

[quartz stratus]

A TextMeshPro NullReferenceException is freezing my game on multiple Android devices. Naturally, it runs fine in the Editor. I'm not doing anything particularly unique with TMP, just using it in my UI.

Here's the error log: https://pastebin.com/zDqCELuS

The line it's failing on is a method inside a C++ file: TMPro.TMP_Settings.get_defaultStyleSheet

I've double checked my TMP_Settings asset -- a valid TMP_StyleSheet asset is assigned to the Default Style Sheet field.

I've tested this in TextMeshPro v3.0.6 as well as the preview versions available.

Has anyone run into this before?

[undone coral]

can you reproduce this

my instinct is that this is a red herring

[quartz stratus]

I wish it was a fluke, but I'm able to reproduce across multiple devices on BrowserStack. Other folks on my team are able to reproduce on their physical devices as well. Oddly enough, my one physical testing device doesn't experience the error, a moto g power.

The same project built to iOS and WebGL doesn't experience this error.

If I can't figure out a solution, I'm hoping I can recreate this in a small project to submit to Unity QA.

[tribal pivot]

That asset comes from Resources right?

The stylesheet, i think by default tmpro makes it in a Resources folder

[quartz stratus]

I believe you are correct. I realized there were other folders in our Asset directory also named Resources, so I renamed them, leaving Assets/TextMesh Pro/Resources as the sole folder with that name. Sadly, this did not alleviate the problem.

[tribal pivot]

I for unrelated reasons copied over the tmpro package into our project, to use it and modify the source. Perhaps that could help you

[quartz stratus]

When I imported TextMeshPro into a brand new project for reference, the TMP_Settings asset is created with some interesting values. For instance, the asset path fields. Default Font Asset Path is set to Fonts & Materials/, Default Sprite Asset Path is set to Sprite Assets/ and Color Gradient Presets Path is set to Color Gradient Presets/. This seems to indicate a pattern -- those are all sub-folders of Resources. However Default Stye Sheet Path is set to an empty string. I tried setting it to a path like the others (Style Sheets/), but to no avail.

[quartz stratus]

I should definitely try this -- thank you.

[quartz stratus]

Just as a follow-up in case anyone comes across this and is looking for a solution -- I'm almost certain this error wasn't responsible for the freeze. I moved the TextMeshPro folder from Library/PackageCache/com.unity.textmeshpro@3.0.6 to Packages/com.unity.textmeshpro@3.0.6 so I could edit the scripts. I then modified the TMP_Text.GetStyle method so it immediately returns TMP_Style.NormalStyle, a static style with default values, since I don't currently use style sheets in our project anyways. That stopped the error from happening, but the freeze still occurs.

[undone coral]

yeah it's a red herring

try modifying your texture compression settings

especially the font atlas texture

[quartz stratus]

Oh good idea.

[undone coral]

can you target android vulkan?

or vice versa - try to targe openglcore?

[rugged ether]

So, when you create and open a script in Unity with Visual Studio, you get auto-complete suggestions for "Awake", "Start", etc.
However I'm using Visual Studio outside of Unity and essentially only supply Unity with the built DLLs.

Can I somehow replicate that auto-complete behaviour in a detached Visual Studio instance?
I know how to get general auto-complete and have that going, I just want to have the auto-suggestions for the Unity Messages as well.
I figured I might have to enable Visual Studio Tools for Unity seperately somewhere, but I can't seem to find where

[gray pulsar]

There's a section on this page about debugging DLLs on this page: https://docs.microsoft.com/en-us/visualstudio/gamedev/unity/get-started/using-visual-studio-tools-for-unity?pivots=windows

Maybe setting the target framework for the DLL to Unity?

[rugged ether]

Those Unity frameworks apparently only exist for legacy editions, I'm using 2021.2 "unfortunately"

[undone coral]

huh?

it should just work

if it doesn't try reinstalling things

in Rider it Just Works

[rugged ether]

Everything works fine if I open VS through Unity, but I don't want that for... reasons.

(edit) I figured it out.
If anyone is interested, i had to add the generated Assembly-CSharp.csproj from Unity to my custom solution and set that as the startup project. That's it.

[foggy sonnet]

I guess this code didn't belong in #💻┃code-beginner but does anyone know what is wrong here?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Platform : MonoBehaviour {

float dirX, moveSpeed = 3f;
bool moveRight = true;


void Update () {
if (transform.position.x > 4f)
moveRight = false;
if (transform.position.x < -4f)
moveRight = true;

if (moveRight)
transform.position = new Vector2(transform.position.x + moveSpeed * Time.deltaTime, transform.position.y);
else
transform.position = new Vector2(transform.position.x - moveSpeed * Time.deltaTime, transform.position.y);
}
}

I got this error message

[frank peak]

go to the Platform game object in the scene hierarchy, double click it, find the script thats missing, right click, remove component and re-add it if it was needed

[foggy sonnet]

Thank you!

[gilded wing]

seeing some performance spikes with Mono.JIT in the profiler, is there anything i can do to make sure these happen e.g. during the loading screen? like other than just calling whatever's causing them also during loading even if there's no actual reason to

like some explicit call i can make

[quartz stratus]

I removed the vulkan api in player settings a while ago -- doing so stopped it from crashing immediately on my test device. But I'll play around with adding it back in.

Right now we only have OpenGLES3 under graphics APIs

[fervent cave]

I'm using vs code with omnisharp, however omnisharp takes up approx. 800MB of RAM, which seems excessive to me and bloats my RAM thus making reloading script assemblies slow. Is there some better setup?

[sage radish]

You will have to run through the relevant code at least once. Note that Mono.JIT will not appear in IL2CPP builds.

[regal olive]

Hi, do you guys know if it is possible to have a SerializedField that wants a ScriptableObject but Automaticly creates a new instance of it an exposes the parameters of the Scriptable Object to the inspector? (Maybe with editor scripting?)

[fervent cave]

pretty sure thats possible

[tribal pivot]

Yes thats possible.

[gilded wing]

ok thanks, i'd like to stay on mono if possible so is there any info or rule of thumb for what exactly gets postponed for JIT? knowing what's gonna cause it would help a lot, rather than having to look for every instance of it in the profiler ...

[regal olive]

Any examples on that our resources to look at? Especially the new Instance creation part. I want it to be very easy to use, and same as if I would use a normal ScriptableObject Reference

[sage radish]

You'll get a Mono.JIT whenever a method is run for the first time or a type is used for the first time.

[gilded wing]

oh duh that makes sense, i guess i was only noticing the ones causing notable spikes and GC

[regal olive]

How do I code something that will trigger a crash plus error message

I saw something on the site with the Abort() function but it doesn't actually show the code

[gilded wing]

i've tried looking this up a few times but i keep getting massive Physics.Processing spikes for no reason, the profiler on deep mode says it's all self time and they happen when running the game on "idle", i.e. they aren't correlated with anything specific in the game

oh wait argh i did "solve" this before, it was having my web browser running (not running the game or anything, just in the background completely unrelated)

just the profiler getting confused i guess as the browser ... hogs some gpu resources or something??

it showing up in Physics.Processing is pretty confusing, lol

it does make me worry about users running into the same thing, though hopefully it's just some kind of rare interaction with specific browsers/sites/whatever

[sage radish]

If there is ever a lag spike for whatever reason, there will be more physics updates next frame to compensate for the lost time.

[gilded wing]

oh right the whole fixed time thing, makes sense though i wish the method was more descriptively named

[gilded wing]

like i guess you can't just change something this fundamental easily but it'd help if it was somehow readable in the profiler that "oh that was actually like 20 fixedupdates all at once" or something

[hollow cedar]

WTF

i've never seen my scene view being on an angle

how do i even begin to fix

[rotund dagger]

Seems like rotating around x

[hollow cedar]

there is no rotation issues in the scene

it'S literally just the scene view

that is on an angle

most of my items have no rotation applied to them

(same with the parents)

if there was a ingame rotation my character's gravity would react to it

[fresh salmon]

If you don't have editor scripts that modify the scene view active, ask in #💻┃unity-talk instead

[hollow cedar]

SAME ON OTHER SCENES

caps

[fresh salmon]

.

[sly grove]

just press on the scene view rotation gizmo

[hollow cedar]

yeah that fixed it ty

didn't think of that

[bitter zephyr]

i dont know if this is an advanced thing, does someone know how to make one way 3d platforms? for the 2d side there is a component but for the 3d there is nothing

[ancient talon]

What exactly happen in the process of Graphics.Blit() call?

or better yet, when I call RenderTexture.GetTemporary, does it ever recycle any old RenderTexture? Or does it get override on the next Graphics.Blit call?

Apparently GetTemporary keeps recycling old materials and mix in with some other materials I didn't want to mix with...

[sage radish]

Blit is drawing a full-screen quad to the dest texture with a material where src is set as _MainTex.

The default material when none is specified just outputs the src texture directly, so it's like copying src to dst

[sage radish]

You have to call RenderTexture.ReleaseTemporary when you're done with it

[ancient talon]

Right, I had problem when loading rendertexture from temporary. It had garbage data in it, mix with new opacity texture on top of it.

I did that

[sage radish]

It will auto release after like 4 frames, but you shouldn't rely on that.

[ancient talon]

the problem is, next call stack recycle that.

I had to call GL.Clear() before calling Graphic.Blit to remove the "dirty" texture I got from the temp.

[urban warren]

I have a design problem that I am going to try to explain.
I am making a system for having a hierarchy of tags.

Animal
 > Mammal
   > Dog
 > Reptile
Building
 > House

(each one is their own tag, but with relations to their children and parent tags)

Tags have an ID and a string name and are stored in a central 'database' file.

Tags can be compared either by checking if they are exactly the same, or if one is an ancestor of another.

Now to actually use the tags, you reference their ID. There is also a collection class that holds references to tags for doing more advanced comparisons/group comparisons.

This is where things get complicated and I have my question. If I want to check if one tag is the parent of another I would need to use the ID of the tag and do a dictionary lookup every time. Which of course doesn't make sense to do, so it seems caching the parents would be the way to go.
The problem here though is that if the hierarchy changes, the cache becomes out of date.

My only two thoughts are either to simply do a dictionary lookup every time, or to use ScriptableObjects for the tags, so they could be referenced that way and the parents could be checked directly without the need for a lookup

[broken socket]

Just a thought before going to bed, don't know if that'll give you ideas: did you consider hashing the whole hierarchy in the ID. Something like Animal/Mammal/Dog. Checking relationship is then a matter of String parsing, dunno if that's more suitable for your case (could easily make things worse).

Also,

if the hierarchy changes, the cache becomes out of date.
I don't see dogs becoming buildings all of a sudden, but maybe that was just a dummy example ^^ Anyway you can still rebuild your cache everytime your relations become dirty

That was my 2 cents, going to bed now, have fun

[north parcel]

Is there a way to check if Visual Scripting is installed in Unity Project? Using scripting?

[shadow seal]

https://docs.unity3d.com/ScriptReference/PackageManager.Client.Search.html A quick search found this

[compact ingot]

you need to use a tree data structure

[urban warren]

Right, but I guess the struggle is referencing the nodes of the tree

[compact ingot]

depends on how you implement the datastructure

i'd say its an ideal problem for to be solved by a custom datastructure

[urban warren]

The references need to be serializable, so that makes me think an GUID. Then have a dictionary with a GUID as the key and a node as the value.

[compact ingot]

you dont need to serialize references in any complicated way if its a properly designed structure

the backing data could be a flat array

containing structs, with a parent field that points to another index in the array

[urban warren]

Oh, then references could just be the index of the tag

[compact ingot]

yes

for efficient traversal you may want to keep a list of child indexes aswell

but you can always generate that from the parent-data, no need to serialize

[urban warren]

Hmm, that would make it very cheap to get tags, no need for caching the parents per-reference I would think as it would be cheep enough to traverse

Something like tags[tags[tagIndex].parentIndex] to get the parent of a tag

Unless I am wrong I would also need to keep a list of 'empty' indices, for indices of tags that were removed.

[compact ingot]

your datastrcture should perform compacting when you remove items

it should always be sparse (no null)

[urban warren]

That would mess up all current references though

[compact ingot]

you would have to update them all

thats the price you pay if you dont use a linked approach

linked = each node is an object somewhere on the heap

[urban warren]

Hmmm... I'm not sure if that would be possible....

[compact ingot]

ofc it is

its a classic coding interview problem 😄

[urban warren]

Not in Unity 😛

My thinking is that you would have a public TagReference _someTag; field. And assign it to a tag in editor

public struct TagReference { public int tagIndex; }

So, it wouldn't really be feasible to edit the index of every TagReference in the project

[undone coral]

when you say tags, do you mean unity Tags?

[urban warren]

I do not. I mean my own tag

[undone coral]

what is your objective?

[undone coral]

what problem is this trying to solve

i see.

[urban warren]

I guess it would be efficiently reference a node in a tree, and efficiently check what it's parents are.

[undone coral]

i meant the real problem lol

like what is the gameplay or

application thing going on here

[urban warren]

Oh oh, I am making a tag system for my game so that I can more easily check data and status in a generic way. I can check if a GO has a Status/Fire tag instead of having to check if it has a Status component and if that component has the enum Effect.Fire

[undone coral]

you can make a tree with nodes of the form

class Node {
  string name;
  Node parent;
  Node[] children;
}

and you can test if name IsAnAncestorOf node using

boolean NodeIsOrIsAnAncestorOfName(Node node, string name) {
  while (node != null) {
    if (node.name == name) {
      return true;
    }
    node = node.parent;
  }
  return false;
}

[undone coral]

okay... i wouldn't say what you are going for helps you solve that

if you want to check if a game object is on fire... get the component, etc. etc.

[urban warren]

Right but the issue is referencing a node in a serializable and efficient way

[undone coral]

referencing what though?

the right way to do this is

if (gameObject.GetComponent<Status>()?.IsOnFire) {
 ...
}

that's fine

you could do a million of these statements

[urban warren]

The node

public class SomeComponent : MonoBehaviour {
  public SomeNodeReference _node;
}

[undone coral]

nah

why not just add a reference to Status at that point?

doesn't make sense

i don't know what is inefficient here

there's no nodes

nodes and trees have nothing to do with your problem

your problem is reading a variable, for which there are many facilities

don't create a new way to read and store variables

it will be inferior to reading a variable

[humble onyx]

you could have a component with a list of all stati that the object has

[urban warren]

What I gave was a simple example, there are many other scenarios where it would be helpful. One would be using it as a param for an event for triggering particles. Or checking as a way to group ScriptableObjects, like if you have an Item SO with a tag field. You could have a slot that only accepts items with a certain tag.

It also acts as a way to abstract the systems from each other.

[undone coral]

if you want to make a group of scriptable objects

MyScriptableObject[] group;

// check group membership
group.Contains(target);

if you want to trigger particles...

...

i think you get it

[urban warren]

I know there are other ways to do this. It isn't like using tags like these are the only way by any means

[undone coral]

there is one best way to do "variables" 🙂

just... do the thing

i cannot wrap my mind around

public class SomeComponent : MonoBehaviour {
  public SomeNodeReference _node;
}

being superior in any example

just being real

[urban warren]

That was just an example of what I meant when I said reference a node.

[compact ingot]

maybe specify the problem again, with all its requirements, maybe this discussion has gone off the rails

[undone coral]

focus on the

concrete problem

not the subproblem of the nonproblem of creating a new way of storing variables in tree form

[compact ingot]

the concrete problem is to make a generic thing

[undone coral]

well

i've done my best

i think you'll figure it out 🙂

[undone coral]

nah...

you are misinterpreting what the profiler is telling you

[urban warren]

I am trying to find a way to serialize and keep a reference to a node in a tree that is stored in a central database(SO, jsons file, whatever).
And then at any point efficiently check the ancestors of the referenced node.

[undone coral]

this is a red herring.

the profiler is telling you what is slow

[compact ingot]

seems like all you need for that has already been discussed

[undone coral]

you can use my predecessor check code to "efficiently" check the ancestors of a tree

[smoky maple]

just based on what I've read I can't see why you need tags like this at all

[undone coral]

you can use a custom property drawer to interact with an "x" in a datastructure "y"

it can be as simple as

[Serializable]
public class InspectableNode {
  public int nodeId;
}
[CustomPropertyDrawer(typeof(InspectableNode))] {
  // logic which interacts with whatever to populate your editor
}

[urban warren]

Yeah, I was going to ask you is it really that bad to not compact the list and instead keep a second list of 'empty' indices? (genuinely asking as I don't have much experience in this area. Is it considered pretty ugly?)

The only other option I can think of is using an SO for each tag as those keep references across scenes.

[undone coral]

none of what you discussed resulted in efficiency gains

i will guarantee you my while loop will outperform 100% of alternatives to "efficiently" encode ancestors

[urban warren]

Maybe a more concrete example would be I have a area in my game where you can place things. Anything from plants to lights to decorations. If they each have tags, I can easily keep track of the different types of objects that are in that area.

[undone coral]

it introduced a lot of potential bugs on top of making things slower

[undone coral]

if you want to see what objects are in an area... enumerate them

if you want to see where you can place things... create a list (or if it's large, a set) that says what you can place, and check membership in it

[urban warren]

Yes, but again I need to serialize a reference to the node so I can get its parents.

(gtg for a bit, feel free to continue as I will come back and read up on what I miss)

[undone coral]

for small groups, an array will outperform a hashset

[undone coral]

you don't need to serialize a reference to the node

you need something that is weird that you happen to want to use the unity editor's inspector to interact with

which will be impossible to do without a custom property drawer

that should be signaling to you that what you want is a bad idea

or can already be achieved by something else

[smoky maple]

impossible? people use ScriptableObjects as tags all the time which already has pog editor support

[undone coral]

the user doesn't want a tag

i don't really know what the user wants

it sounds like a reinvention of "variables"

the idea of having "variables"

you already have variables

variables, but also, classes..

it's tough to say!

sometimes classes, but also sometimes, just group membership

[gray pulsar]

I might be making connections that aren't there, but it sounds like they're trying to do ECS, or at least part of it

The way they talk about tags sounds a lot like ECS components to me

[smoky maple]

based on this it just sounds like they want tags, so you can just create a "Tag" SO and name it whatever your tag is

I think you're over complicating it

[languid isle]

anyone familiar with game objects being stored in lists?

[smoky maple]

yeah actually I agree with this

Unity ECS would automagically give you a "tag hierarchy" thing where you can get every object with House + Fire or Plant

and do it in a super performant way with archetypes and chunk management

[smoky maple]

https://dontasktoask.com/

[languid isle]

Ok so I am storing a game object with a script in a list. The Game Object is called TTScore. The Script is called DefaultScores.cs, and it has variables in it "Initials, Score, Deaths and Level.

What is the proper syntax to get the variables for the objects in the list?

is this the proper syntax:

Debug.Log("This is for index 10.  Initials: " + theDirtyDozen[10].GetComponent<DefaultScores>().initials```

?

[sly grove]

this is #💻┃code-beginner stuff

but yes, that's pretty much the correct syntax

[languid isle]

ok ty

^_^

[sly grove]

assuming you spelled everything right

[languid isle]

yes

Ok so the NAME of the Object doesn't matter at all then

ok

😄

I was trying to call the object by name.

[urban warren]

That comparison is not entry inaccurate. I guess I would put it like this, it is just like how you would use Unity's Tag system, but with a hierarchy and more data oriented (at least in my use)

But @smoky maple is right, it is basically just SO tags. I have several reason why I don't want to just use SOs though, they feel more cumbersome than what is needed., the API is messy(for this use case) and they clutter the project browser.

I might still end up using them though as they allow for being referenced across scenes and assets easily. And I can have them as sub-assets of a main one.

[urban warren]

I do want tags. Perhaps some of the examples muddied the waters so I apologize. Its just a unique identifier which can be used for comparisons.

(And has hierarchical information)

Ok, no one can help me in #💻┃code-beginner so I hope someone here can.
My atrocious code: http://pastie.org/p/5AhlwthDvcxC38FsXBdy76

So, what I'm doing at the moment is my 2d gameobject table occupies a 4x4 tile when I place this table on my tilemap during runtime I keep track of all 4 sprite because my table gameobject is split into 4 different sprites so each sprite will occupy a tile and not only that I place them manully on the tilemap as you can see in the code. What I want to do is keep my table gameobject into a single gameobject and tell my tilemap to treat it as a 4x4. This will make it easier for me as a implement more gameobjects and bigger objects in the future and as well adding new features such as highlighing the gameobject when selected by the player.

[compact ingot]

Is there a question?

[rustic scroll]

Hey folks, im tinkering on a solution to share parts of a game with a server. I can isolate that part into a .net standard library and import in the project as a plugin but that's not really handy for development.

Was wondering if there's a way to either compile the unity game as a .dll that can be imported into other projects or any ideas on what be a good practice to do this.

[compact ingot]

Sharing a library dll is the way to do it (you can use a build script to automatically copy it to the client/server projects or publish it as a package they both depend on), if that’s inconvenient make the server and client the same app/project

[rustic scroll]

The inconvenience of having to copy the dll is mainly for debugging and cross team development - its still something doable. Using the same app/project would mean i gotta run a unity game as a server right ? ( Like Mirror )

[gleaming dagger]

nvm someone was able to help me on #💻┃code-beginner but thanks

Yes

Hello everyone, I play the game VRchat, Recroom and I thought how did they make it possible to load so many rooms within the game for download? Do they use addressables/asset bundles?

[undone coral]

lol

is this on a 5x5 board?

[soft hawk]

7x12

5x5 is too short

[undone coral]

have you run the profiler

to see where the time is lost

[soft hawk]

Oh no I mean physically too short, like not tall enough

pieces are 1x2 and spawn vertically

[undone coral]

i meant have you generally looked at the profiler

[soft hawk]

oh, ya

The best solution I could come up with for rewards was to rank the next valid moves

so thats the step thats taking the most time, for sure

[pastel wagon]

Is there a way to spawn a new OS window (possibly using mono winforms maybe?) and then draw a Unity RenderTexture to it? I’m trying to make a separate window that can be captured as an overlay for streaming

[sly grove]

https://docs.unity3d.com/Manual/MultiDisplay.html

[pastel wagon]

Hmm, specifically this is for a mod, so I don’t have direct control over setting up displays..think that still might work?

[sly grove]

no idea

[pastel wagon]

Harmony might be an option though..

[sly grove]

It's pretty much either using Unity multi display or using a native windows plugin

[pastel wagon]

Native is also an option - just not sure how to draw the texture to it

GetNativeTexturePtr?

[sage radish]

You could also send the texture pointer directly to an OBS plugin, if it's going to end up in OBS

That's what this plugin does, though not related to Unity
https://obsproject.com/forum/resources/openvr-input-plugin.534/

[pastel wagon]

That’s an interesting idea..I have a couple other use cases in mind that aren’t specifically for streaming though too (like hooking up small dedicated screens)

Seemed like making a new window would solve both

[sage radish]

Then I think your best bet is to just send the texture pointer from Unity to another process. It's probably not going to be fun to try to manage a separate window from within a mod within a Unity game.

Hey everyone, I have a UnityEngine.UI.Toggle, and I want to intercept the event when it's clicked/submitted to do some validation and potentially stop it from being toggled on if the validation fails. I can hook into the onValueChanged event, but this is too late as the toggle will already happen and trigger callbacks/events (like untoggling others in the Toggle group). I'm not really seeing or at least understanding a way to do this, does anyone have a direction that would make this doable?

[compact ingot]

Put a proxy handler between the toggle and any other subscribers by having them subscribe to a similar event on the proxy that gets invoked only when your validation succeeds

[marble cloak]

I'd like to, but what I'm struggling with is how to avoid the built-in subscription of the click/enter event that toggles the toggle state and switches off other toggles in the group

[sly grove]

turn off raycast target on your toggle and put a proxy invisible button in front of it instead that runs the validation check and then toggles the toggle if it succeeds

[marble cloak]

Yeah I thought about replacing it with a button then swapping to the toggle or something similar. I don't think an invisible one on top would work because I still need the navigation animation (selection, hover, etc.) so I'd need the button to completely replace the toggle for navigation purposes (otherwise like with keyboard you'd still select the toggle and press submit on it). I was hoping I could just intercept the event instead but doesn't seem possible.

Oh maybe I can extend the Toggle class and override the OnSubmit and OnPointerClick methods

[sly grove]

you can get all of the navigation animation stuff by setting the transition target on the invisible button to be the toggle's graphic

basically set its transitions up exactly as the toggle's transitions are set by default

[compact ingot]

a button with custom handler is often the easiest way to make a ‚fancy‘ toggle instead of hacking a builtin toggle into submission. You can also make a fully custom widget by inheriting Selectable and implementing IPointer.

[marble cloak]

Yeah extending the Toggle class with my own and overriding OnSubmit and OnPointerDown is exactly what I was after, something like:

        if (Validate()) {
            base.OnSubmit(data);
        }
    }```

I think I'd rather make a custom fancy toggle from a Button instead of trying to have an invisible button and make sure the navigation and animations make sense between both of them. And yeah, agreed, toggle are surprisingly not helpful, like you can't even easily get the currently selected toggle from a group???

Hey guys! I have several Head meshes containing 3 submeshes ( skin, eyes, teeth ). The problem is that the submeshes are not in the same order for all the Heads, which is a requirement for a task I'm working on. Is there a way to permanently modify the submesh order? I've tried swapping the submeshes of the sharedMesh and it works until I restart the editor or reimport the mesh. Is there any way to do this permanent?

The code that I'm using for the submesh swap is:
var swappingSubmesh = meshToUpdate.GetSubMesh(swapIndex1); meshToUpdate.SetSubMesh(swapIndex1, meshToUpdate.GetSubMesh(swapIndex2)); meshToUpdate.SetSubMesh(swapIndex2, swappingSubmesh);

where meshToUpdate is the sharedMesh

[granite viper]

you need to save the change back to the asset

if it's getting imported from an external file then you can't permanently modify it bc it'll be overridden by the import

but you can create an external clone in import and modify that

[azure hinge]

hey @granite viper thanks for answering! I appreciate it! Do you have any suggestions on how to save the change back to the asset? Are there any links that I can follow? I've read the Unity documentation and they said that modifying the sharedMesh is permanent, so I thought that should take care of it

[granite viper]

I don't have enough context

where is the sharedMesh coming from

an external mesh file?

[azure hinge]

The code from the submesh swap belongs to an editor tool I created that modifies an imported mesh in Unity. Modifying that imported fbx and making sure it's permanent would suffice.

I'm assigning the mesh as a reference to the asset in editor mode

[tribal pivot]

Check out AssetDatabase.CreateAsset to save to disk

[granite viper]

something you can also register an asset preprocessor

[azure hinge]

I've tried doing that, but it failed stating that the mesh was already an asset

[granite viper]

you'd need to save it to a separate location

you can't save it back to the original file

try this: https://docs.unity3d.com/ScriptReference/AssetPostprocessor.html

actually you'd want the postprocessor

https://docs.unity3d.com/ScriptReference/AssetPostprocessor.OnPostprocessModel.html

[azure hinge]

will take a look! Thanks! I appreciate the help!

[undone coral]

modify the FBX file to have the correct order. you can convert it from binary to text format to do this

FBX binary -> FBX text -> modify order -> FBX text -> FBX binary

don't try to modify this in a post processor

too many pitfalls

[tacit axle]

helllo any way to create a quaternion from scratch in unity ?

like with control over all parameter

[sly grove]

I already mentioned yo you above...

or rather in the other channel

[tacit axle]

yes but its not what i need

[sly grove]

what do you need

[undone coral]

ah, the ol' Homemade Quaternion

[tacit axle]

yes

this look up

[undone coral]

six pages of personal story about grandma's quaternions

[tacit axle]

ill wait for the end

[shadow seal]

I mean you can make a new Quaternion(0, 0, 0, 0) but why on Earth would anyone do that

[sly grove]

Dunno what you're asking but all the ways to create a Quaternion are listed here https://docs.unity3d.com/ScriptReference/Quaternion.html

as I said before

[tacit axle]

to leeeeeeearn

[sly grove]

except I guess...

Quaternion q = default;
q.x = ...
q.y = ...
etc...```

[undone coral]

first, your ingredients: start with 1 w

bring your w to a boil, lightly salted

[tacit axle]

furiously take not

[sweet summit]

Are there any good utilities for compressing byte[] audio data thats being sent over a network rapidly?
DeflateStream seems to work so far but i'm looking to compress the data more heavily

[undone coral]

if you want to "make quaternions" you'll have to learn the math straight from a text book

there are many insights before you can understand what they are

[tacit axle]

so this

[undone coral]

it's very mathy

[tacit axle]

i know ...... i know

too much

[sly grove]

yes that, but if you don't know what those x, y, z ,w are (I certainly don't, not without a refresher) then it's not useful

[tacit axle]

dont hurt yourself in the refresher

[sly grove]

Much more useful in day to day life are these:
https://docs.unity3d.com/ScriptReference/Quaternion.AngleAxis.html
https://docs.unity3d.com/ScriptReference/Quaternion.Euler.html
https://docs.unity3d.com/ScriptReference/Quaternion.FromToRotation.html
etc...

[undone coral]

they are basically a thing that, when using multiplication alone, gives you numbers that are periodic

and they're way more complicated because it expresses the periodic properties of 3d rotations

whereas 2d rotations are pretty basic

[tacit axle]

this one is very good to start https://www.youtube.com/watch?v=d4EgbgTm0Bg

[undone coral]

well.. unless you do the textbook problems

you're not going to get this insight

what's your objective?

[tacit axle]

learn to use quaternion and get a feel for them

[undone coral]

you definitely want to use Quaternion.AngleAxis and Quaternion.FromToRotation

[undone coral]

that is a math class problem not a unity problem

[tacit axle]

because i don't know how thos function work internaly

[undone coral]

hmm.. the way to express rotation sin quaternions is 1 piece of a 10 piece puzzle

[azure hinge]

thanks for your suggestion! How do I convert the FBX to text? Is there any built-in option in Unity? I haven't found any

[tacit axle]

easy puzzle then

[undone coral]

if you are exporting from a 3d graphics program that's the easiest way

otherwise use a utility on github / autodesk

[tacit axle]

thx all

[azure hinge]

got it, thanks! 👍

[sly grove]

You don't need to learn how they work internally to get this feel and knowledge of how to use them. Remember I wrote that rotation/normal sticking code for you with Quaternions. And I have very little idea of how they work internally. I just know how to use them, compose them, create them, and work with them.

[undone coral]

based on my research online

[tacit axle]

yes but im still confused about it so i want to learn about them intimately and also i didnt find a way to smooth the rotation + i had a gimble lock problem so i want to start over

[tacit axle]

its a 10^100 piece puzzle is it ?

luckily

i got cookies

[undone coral]

you could try to do #4 from https://people.math.harvard.edu/~elkies/M55a.02/pdflatex/pp.pdf and you will understand quaternions

at a deep level

for me to answer these would take like 100 hours

[sly grove]

you don't need that knowledge to solve either of those problems. I don't want to discourage you from learning, but I'm telling you it's not necessary.

The best thing to learn is just what Quaternions are and how they interact when you combine them, e.g. by composing them with *

[tacit axle]

i know thats why im doing it

[undone coral]

if you've never written proofs at a university mathematics level then you should start with that

honestly i'm not sure i'd get it even after 100h

i didn't do well in 23a

[tacit axle]

i hate proof i prefer proof by "good enough"

if it work it work

it is what it is

those 3 are good

[undone coral]

hmm

[tacit axle]

btw can i get a stack overflow if i let the debug.log every frame for too long ?

or is there a safety ?

[undone coral]

you won't get a stack overflow

[tacit axle]

thx

make sense

what does it mean here ?

[soft hawk]

I'm training a neural net to play my game

cumulative reward going up means that it's getting better at playing

if the number is positive (in my specific case) it means that the ai is making good moves more often than bad moves

How do I load an audio file from out of unity?

[grim oxide]

I have a single component that is getting rather large in size. I could divide it into multiple components, but that would be purely for organizational purposes, because none of those components would ever be reused separately. They would literally all just Require each other.

Are there any performance concerns with doing so? Splitting functionality across multiple components?

And is it worth the grief with sorting out script execution order

[unkempt nova]

Not really. Unity was made to be used like that. You might notice faster compile times splitting it up, if you edit one

[grim oxide]

Oh really? 🤔

[unkempt nova]

Depends how big it is

When I was first starting out, I had a massive 6k line God component on my players. Would take ~30s to compile each change. Splitting it up was a huge difference

[grim oxide]

Oh wow lol. Mine is nowhere near that ,compile times haven't even been an issue yet, it's just an organizational concern

I've been itching to bust it up but felt like more components might be a hit on performance

It's getting to be a bit of a mess lol

[unkempt nova]

I personally feel like if they all require eachother and will never be reused, not a whole lot of point in separating them out

But you could likely get them to not require eachother, but that sounds like pain

[grim oxide]

not a whole lot of point in separating them out
Like I said just working on the file is starting to be a mess, organizational schemes coming apart at the seams trying to keep relevant things somewhat together lmao

It's 'only' 1k lines

[unkempt nova]

Yeah that's a bit big

[grim oxide]

Here's another question for you anyone

From what I can find properties are wonky with Unity, correct? Tricky with serialization or something?

Actually, better way to put it, do you use public fields, private with [SerializeField] or properties (somehow?) 😛

[granite viper]

wut

oh I had to reread that a couple times

what I use entirely depends on the situation

since I don't use custom serialization I don't use properties

[grim oxide]

A lot of unity stuff seems to just make literally everything public fields and say F it

Which goes against my usual programming instincts lol

But without properties you have to do getters and setters which is 🤮

[smoky maple]

Fun tip you can do
[field: SerializeField] on an auto property to serialize the backing field, and it'll work just like normal

[austere jewel]

If by normal you also mean the name that is serialized is <PropertyName>k__BackingField, sure 😄

[smoky maple]

That's not an issue anymore right? xD

[austere jewel]

It won't appear like that in the inspector, but it will serialize as that

which makes it difficult to work with when refactoring (using FormerlySerializedAs), or making editors or property drawers (using FindProperty).

[smoky maple]

Woah I guess I've just never run into an issue with it

[hoary mango]

If I use different layers, will masks in different layers not interact with each others?

[tribal pivot]

What mask are you talking about? Culling mask, ui mask, physics layers?

[hoary mango]

I want to make several culling masks on different sprites and I don't want them to interfere with each other

[frank moat]

Hi, i'm trying to make an external C# program press virtual keys in a unity project. So far I've got something to the effect of ```cs
[DllImport("user32.dll")]
private static extern bool PostMessage(IntPtr hWnd, UInt32 Msg, int wParam, int lParam);

private static void PressKey(Process proc, int aKeyCode) {
const UInt32 WM_KEYDOWN = 0x0100;
PostMessage(proc.MainWindowHandle, WM_KEYDOWN, aKeyCode, 0);
}
```in the external project. This works perfectly when the process i'm calling PostMessage with is a text editor of some sort(vscode, notepad, discord, and so on...) but when i try it with Unity it seems to not receive or at least react to the key presses being sent. Does anyone know if you need to do something special with Unity to make it accept the inputs? or am i perhaps using PostMessage incorrectly? Thanks for any help 🙂

[final steeple]

1. That P/Invoke isn't correct (you have some pointer-sized values passed as int, among other things), it should be:

[DllImport("user32", SetLastError = true, CharSet = CharSet.Unicode)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool PostMessage(nint hWnd, uint Msg, nuint wParam, nint lParam);

(Replace nint with IntPtr and nuint with UIntPtr if nint and nuint aren't available in the C# version you have)

2. You should call Process.Refresh before retrieving MainWindowHandle, because the Process object may be outdated. That said, I don't believe MainWindowHandle works properly in Unity (iirc), you instead need to query for all window handles in the process and call PostMessage on those.

[frank moat]

thanks! I greatly appreciate the help. I think i've managed an implementation of your suggestions now. however, it still refuses to get any keystrokes to unity

[final steeple]

What value are you getting from MainWindowHandle? It might be IntPtr.Zero, which would just send the messages to the current process

[hexed quest]

Hello everyone. My event triggers do not work with my instantiated prefabs. The units I instantiate onto the board do not respond to the event triggers. Static objects that I created in the hierarchy, however, do. Does anyone have a solution? Let me know if more info is needed!

https://forum.unity.com/threads/event-trigger-doesnt-work-on-instantiated-prefabs.427481/ this person I think had a very similar problem to me, I wasn't able to apply the solution though

[frank moat]

the process id is a non-zero value and the 3 window handles i got under the process seem fine aswell

[final steeple]

Unity might ignore inputs received through window events in favor of using its own input system

[frank moat]

forgive me if i'm uninformed, but i don't see how unity would read keyboard events without getting them from a windows message loop?

and should not a PostMessage to such a loop be indistinguishable from a hardware device as far as the process is aware?

[final steeple]

DirectInput is one option

or the Windows raw input API

(Which can still receive input through the message loop, but not through the older WM_KEYDOWN-like messages)

Okay yeah, looking at disassembly of a function inside the editor (GetMessageEventName)

It only cares about WM_INPUT

Which is translated to Unity's own Application.Message.Input

[frank moat]

alright, i'll give WM_INPUT a shot then...

[final steeple]

Ok yeah, looking further, it listens to the mouse-related WM_ events, but for anything else it only cares about WM_INPUT

[frank moat]

interesting

[final steeple]

I mean, it's totally possible I'm reading this wrong, but that's what it looks like so far

[frank moat]

i'm currently trying to whip something up capable of sending a WM_INPUT event but it seems more involved than the WM_KEYDOWN event

[final steeple]

Yeah it's quite a bit more complicated

As a test you could try sending WM_MBUTTONDOWN and see if Unity reacts to it, just to make sure I'm not misreading how it responds to messages

That's one it doesn't ignore, as far as I can tell

Looks like you'll need to P/Invoke GlobalAlloc, GlobalLock, GlobalUnlock etc to create a WM_INPUT event manually, since it requires handles

[frank moat]

yeah, from what i'm reading it seems like if it needs a lParam pointing to memory alloacted with Marshal.AllocHGlobal and written into with some arcane magic. the API only seems to document how to receive it and nothing about how to generate one 😖

[final steeple]

Specifically it needs a handle to that memory, not an address to the memory itself

Which isn't something you can get with AllocHGlobal

You'll need to P/Invoke the actual GlobalAlloc etc functions

[frank moat]

great... more fun...

but yeah i'll give WM_MBUTTONDOWN a shot aswell and see if it likes that atleast...

[final steeple]

Since this is an external application and not something in Unity, you can add the TerraFX.Interop.Windows NuGet package

It has all of the proper P/Invokes and stuff for this already

You'll need these imports:

using TerraFX.Interop.Windows;
using static TerraFX.Interop.Windows.Windows;

And then you can use the APIs as if you were writing C

var hInput = GlobalAlloc(GHND, (uint)sizeof(RAWINPUT));
*(RAWINPUT*)GlobalLock(hInput) = new RAWINPUT
{
    // ...
};
GlobalUnlock(hInput);
// send event with hInput as your lParam

(you need to enable unsafe code in your project though, of course)

[frank moat]

i seem unable to install the package? i'll try with a fresh one, hang on...

[final steeple]

Which .NET version is the program using?

Ideally .NET 6

[frank moat]

currently net5.0

[final steeple]

.NET 5 is going out of support soon, I'd recommend moving to net6.0 yeah

In fact I think the latest version of the package requires .NET 6

[frank moat]

ah, i see

i'll jump ship then...

[frank moat]

sorry to ask a more basic question but i seem unable to install .Net 6 from the Visual Studio Installer. i can't see the SDK for it in the component list

[final steeple]

You can install it from the .NET website https://dot.net/

[frank moat]

yeah, i tried that aswell but it doesn't come up as an option for new project

[final steeple]

Yeah you'll need to edit the csproj file to target net6.0

Are you using VS 2019?

[frank moat]

yes

[final steeple]

Only VS 2022 "officially" supports .NET 6

So for 2019 you need to edit the csproj, yeah

You can also use the dotnet command-line tool

[frank moat]

i tried editing it aswell but it only complained at me

[final steeple]

dotnet new console -n ProjectName
cd ProjectName
dotnet add package TerraFX.Interop.Windows
dotnet build -c release

I haven't used VS 2019 for quite some time, so I'm not sure of the specifics of what you need to do to target .NET 6 beyond editing the csproj though

[frank moat]

oh wait, i got it to compile

seems it sorted it self out after a sdk repair and a restart

haha! slowly climbing back out of the rabbit hole 😉

[final steeple]

Now comes the hard part lol

[frank moat]

yeah. boggles the mind that this is supposed to be the easy bit

ok, next problem. how do you init the structure? ```cs
unsafe {
HGLOBAL hRaw = GlobalAlloc(GHND, (nuint)sizeof(RAWINPUT));
RAWINPUT* pRaw = (RAWINPUT*)GlobalLock(hRaw);
// init pRaw here?
GlobalUnlock(hRaw);

External.PostMessage(hWnd, WM_INPUT, 0, hRaw);

}

[final steeple]

As in, how do you assign to it, or do you mean what do you even put in there?

[frank moat]

what to put

[final steeple]

That much I don't know

[frank moat]

setting should only need a dereference yea?

[final steeple]

yeah

https://docs.microsoft.com/en-us/windows/win32/api/winuser/ns-winuser-rawinput

Looks like RAWINPUT is basically a union of input structures, with a header describing which one it actually contains

[frank moat]

ah, so basic tagged union

[final steeple]

yeah

*pRaw = new RAWINPUT
{
    header =
    {
        dwType = RIM_TYPEKEYBOARD,
        dwSize = (uint)sizeof(RAWKEYBOARD)
    }
};

I was typing this out, but I'm not actually sure how you're meant to get a device pointer

I assume you just enumerate keyboard devices using raw input and pass one of those in

https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getrawinputdevicelist yeah

[final steeple]

btw TerraFX exposes PostMessage so you can just do PostMessageW(hWnd, WM_INPUT, 0, hRaw) https://source.terrafx.dev/#TerraFX.Interop.Windows/Windows/um/WinUser/Windows.cs,450
Though you'll need using static TerraFX.Interop.Windows.WM; too

or rather PostMessageW((HWND)hWnd, WM_INPUT, 0, (LPARAM)hRaw); probably

[frank moat]

ye, PostMessageW((HWND)hWnd, WM_INPUT, (WPARAM)0, (LPARAM)hRaw) even

[final steeple]

0u might work instead of (WPARAM)0, I think it has an implicit cast from an unsigned int

[drifting galleon]

this is an option, but i recommend a newer approach, in case you didn't know about it yet. there's the CSWin32 project, that uses source generators to give you up to date, project specific code without unneeded api's. https://github.com/microsoft/CsWin32 especially for non-unity projects, i highly recommend it. @frank moat

[final steeple]

TerraFX.Interop.Windows is also generated

CsWin32 and TerraFX.Interop.Windows actually share a bit of architecture

Personally I don't like CsWin32 for a number of reasons, but they both get the job done

[drifting galleon]

oh? like what? i'm curious.

[final steeple]

I'm not a fan of the generator approach, at least how it's done currently. Editing a text file feels super clunky, and I don't like the way it deals with marshaling

TerraFX is basically the one to use if you want 1:1 signatures

It also provides a lot of niceties for COM interop

[drifting galleon]

the 1:1 signatures approach is exactly why i do not like TerraFX, without the marshalling handling of the generator you lose a lot of safety

[warm adder]

Hya. I'm instantiating folders full with prefabs in editor mode, using Resources.LoadAll and looking up typeof(GameObject). They spawn, but the prefabs are all completely unpacked. Any suggestions for instantiating prefabs in editor mode?

[final steeple]

Marshaling can have a significant performance cost, and arguably marshaling can be more unsafe depending on how the function works

I understand the argument for either, and personally my stance is "pick your preference"

I just don't like CsWin32 myself

[drifting galleon]

recommendation: do not use the resources folder. it'll mess with the maintainability of the project immensely

[final steeple]

Addressables are usually the better option, though the Resources folder still has its uses

Just be aware that anything in the Resources folder will never be trimmed from a build if it isn't referenced

[drifting galleon]

that is true. but i was under the impression that CsWin32 was also explicitly striving for providing the best marshalling option. so....
but yeah. i guess 'pick your preference'

[warm adder]

whats the better way of doing it? I have no commitment to the recourses folder

[final steeple]

Addressables

You basically get the IResourceLocations of each asset, and then you can load those

[warm adder]

checking it out now, thanks

[drifting galleon]

i do understand the text file feeling clunky, but, it's not all that bad. what i might see as a better alternative is putting the api's in property groups like for implicit usings

[final steeple]

The approach you generally take with TerraFX to remove unused stuff is to publish a trimmed build

eg -p:PublishTrimmed=true

The generator approach CsWin32 takes is an interesting idea, but I feel it's unnecessary and makes it harder to make reproducible builds

[drifting galleon]

yeah, but i don't really like trimming. takes more time to build and might not trim all

[final steeple]

The trimming infrastructure in .NET 6+ is really good

It doesn't really take that long to trim

[drifting galleon]

um, 'harder to make reproducible builds' exactly how?

[drifting galleon]

yeah, but still not finalized and i've experienced a few issues

[final steeple]

You don't have a versioned library to depend on, if the data the generator uses to produce signatures changes, then so does your output

[drifting galleon]

but that's actually a problem imo. if you build for a different windows where the api you're using isn't available, you won't get errors with a versioned library. you'll immediately get compile errors with the generator

[final steeple]

That's what the OSPlatform analyzer is for

If you try to call an API that isn't supported on the current platform, you'll get a build warning

There's OperatingSystem.IsWindowsVersionAtLeast etc

all of the TerraFX APIs are annotated with the SupportedOSPlatform attribute to work with that

It's a much better approach because it also allows you to produce a single dll for all platforms if you desire to

[drifting galleon]

:/// i guess it's really a preference. i'll like to keep it slim and down to the metal

[drifting galleon]

SupportedOsPlatform is not from TerraFX though. the generator also has this

I know, it's part of .NET itself

I'm just saying it's an overall better approach because it lets you publish an "all platforms" build, but also a trimmed per-platform build

you get the best of both worlds, basically

[drifting galleon]

hm, idk.

anyway i wanted to ask, do you have a bit experience with asp web api? or anyone here currently?

[final steeple]

I don't have much experience with web-related stuff in general, I consider myself lucky lmao

[drifting galleon]

true. unfortunately i am now stuck with my project

anyway, if anyone has an idea of how i can add a custom json converter for the web api json deserializer to work with on parameters / or how i can change the schema of a parameter, that would be massively appreciated

How do I sort an array of gameobjects alphabetically by name, in an editor script? Ive been trying to use OrderBy and iComparable etc but I cant seem to wrap my head around it

I keep getting ArgumentException: At least one object must implement IComparable.. errors

and I cant seem to find another way to sort an array alphabetically, lacking some serious Google-Fu today

[drifting galleon]

.OrderBy(static gameObject => gameObject.Name); should work

[warm adder]

Doesnt seem to work im afraid. No errors, but the list remains unsorted

I'm just using it like convertedObjs.OrderBy(static gameObject => gameObject.name); that's correct right?

[fresh salmon]

It returns a new list

Doesn't sort in place

[warm adder]

hmm I can't assign it to a List<GameObject> . Types mismatch?

[fresh salmon]

Yeah, you need to call .ToList

[drifting galleon]

if you have a list and want to sort it, use .Sort() instead, otherwise reassign it

[warm adder]

yeah the .Sort gave me the ArgumentsExceptions

[hollow garden]

just smtn like ```cs
list.Sort((a, b) => a.name.CompareTo(b.name));

[warm adder]

I got it to work. convertedObjs = convertedObjs.OrderBy(static gameObject => gameObject.name).ToList();

[drifting galleon]

👍 yeah

[warm adder]

So, just so I understand, instead of implementing iComparable, we're giving the OrderBy function the parameters of the ordering

[drifting galleon]

correct. if you had something like cost then .OrderBy(static object => object.Cost);

[warm adder]

And, the implementing of the iComparable meant a function in the class that's using the OrderBy / Sort, correct?

[hollow garden]

IComparable is just a CompareTo function

[drifting galleon]

IComparable you only need when you use .CompareTo() to compare something

[hollow garden]

like here

String implements IComparable so this works

[warm adder]

Ahh I see, I see

thanks guys!

always good to learn something on a saturday 🙂

[frank peak]

So i have three classes, Character Data, Character Save Data, and Game Data. Character Data is a container for data attached to a NPC and before save is transferred to Character Save Data, added to a Game Data class (basically a wrapper) and then saved in XML.

this is following a shitty implementation of the Memento pattern

[median cosmos]

hey there I'm having a really long issue

so this is a lot of code, I know

I want to create a 2D endless runner game with a tilemap-system for the ground

and it should sometimes spawn a 1-block higher platform consisting out of a random length of blocks

and based on what neighbour the tile has it should change to a different version, meaning it should turn into a different tile for example that connects to the left or right

however it always spawns the same tiles and I have no idea why

I figured out it had to do something with the SpawnSpecificTile-function that is called in SpawnTiles() where the green comment is

[gray pulsar]

you might have to call RefreshTile on the tile after you set it

[median cosmos]

oh thank you

though I thought it changes the graphics automatically

even when I refresh all the tiles it doesn't change anything @gray pulsar

[tender badger]

How do I set class variables in scripts without having them attached to a gameobject?

Basically, I have spaceships that can be customized with different modules. The modules obviously have differing textures.

I want to make it so that the texture is attached to the module, and whatever I'm using to render it can just call module.texture to get the texture.

[noble granite]

anyone have the source code for Random.GetInsideUnitCircle(out Vector2) or how the method works?

[compact ingot]

Modding discussion is not allowed in this discord.

[noble granite]

i'm not discussing modding tho, just asking if anybody knows how i can get the same effect as GetInsideUnitCircle

[drifting galleon]

wtf why?

[noble granite]

i can rephrase the question if its an issue

[compact ingot]

Because it is generally indistinguishable from a license breach of the target software

[noble granite]

i'm not seeing anything

[noble granite]

the devs' of the game are cool with it

and its not illicit modding

[drifting galleon]

RISE UP for mainstream modding

[noble granite]

i don't see why its an issue

[compact ingot]

That is not relevant

[noble granite]

it's their software...

[drifting galleon]

any game can be modded

[shadow seal]

I think it is well known that this server does not allow the discussion of modding

[drifting galleon]

and devs should never oppose it. boycott all devs that do that

[tender badger]

Then it should be added to the rules, because I checked the channel too and didn't see it there.

[drifting galleon]

rise up for freedom of creativity

[tender badger]

^

[shadow seal]

How about intellectual property rights

Or do we not enjoy private ownership

[tender badger]

.

[drifting galleon]

you don't own the software after you mod it, but you own your parts

[noble granite]

again, it's their software, they're perfectly in their right to disallow modding

[tender badger]

Also, even if they didn't allow it, it would be fine as long as you didn't publish or share it and solely did it for personal use.

[compact ingot]

That is not relevant as nobody here wants to verify that

[noble granite]

depends what the mod does

[frozen imp]

As long as it doesn't touch ripping the assets and decompiling the code it is fine.

@noble granite You are looking for https://docs.unity3d.com/ScriptReference/Random-insideUnitCircle.html

[drifting galleon]

private ownership is bullshit anyway. it's only there to strip money from people

[shadow seal]

That's laughable

[tender badger]

I'm definitely in support of modding, but that argument is shitty, people gotta pay their bills somehow.

[drifting galleon]

you cannot even patent software

[noble granite]

i am, but that has been stripped by IL2CPP, i'm wondering if there's another way to calculate it

[compact ingot]

Most idiotic statements since the invention of civilization

[shadow seal]

Have you heard of copyright

[tender badger]

Fogsight, if you're still here, is it fine if I repost my question in #archived-code-general, as it was buried here by this conversation.

[shadow seal]

Patents protect inventions

[noble granite]

otherwise known as 'illicit modding'

[frozen imp]

sure

[drifting galleon]

you mean the thing that prevents creative people from improving existing products?

[shadow seal]

I think we're a bit off topic, but I think you're a joke

[frozen imp]

Not sure what you are talking about. Make sure you're not mixing it with System.Random

[drifting galleon]

thanks. 👍 enjoy capitalism

[compact ingot]

Here is how to implement a decent function yourself https://stackoverflow.com/questions/5837572/generate-a-random-point-within-a-circle-uniformly

[noble granite]

okay so, i'm modding a game where UnityEngine.Random.insideUnitCircle has been stripped by IL2CPP since it is not used. Thus i can't use it. So i need to calculate a random point in said circle myself, since i cannot access the property getter.

anyway thanks Anikki

[compact ingot]

Basically get a random number between 0 and 1 multiply by 2 * PI, generate a random radius, convert that point defined by the arc and radius to Cartesian coordinates

[drifting galleon]

why is there a strive for this in the hardware sector https://repair.eu/, but not in the software sector?

[compact ingot]

It’s called open source software and is abundant

[tender badger]

Be sure to take the square root of your radius normalized to 1 if you want an even distribution within a circle, or else points in the middle will be denser.

[hollow garden]

it's very easy ```cs
while (true) {
var x = (Random.value * 2f - 1f) * r;
var y = (Random.value * 2f - 1f) * r;

if (x * x + y * y < r * r) {
return new Vector2(x, y);
}
}
``` pop that in a method with r as a parameter

[hollow garden]

or just use rejection sampling, as i show

[tender badger]

Dude, stop bringing politics into a Unity programming support channel, everything has a place and time but that's not here and now.

[hollow garden]

although if Random.value has also been stripped then just use some System.Random bullshit if you can

[compact ingot]

This will not be uniform and inefficient

[drifting galleon]

that is distinctly different. RTR does not depend on open-spec-hardware. it specifically targets company hardware that is not open

[hollow garden]

it is uniform and more efficient than sin and cos

as long as Random.value is uniform which it is afaik

[compact ingot]

Still wouldn’t use it since it’s not guaranteed to terminate

[hollow garden]

it is tho

[tender badger]

Yeah, just do the square root thing.

[hollow garden]

on average it only needs like 1.2 tries

ye

4 / pi is roughly 1.273

[compact ingot]

That doesn’t guarantee it terminates in all cases

[hollow garden]

why not

[compact ingot]

the rng could always produce points outside the circle

[hollow garden]

yes

[tender badger]

Technically there is an infinitessimally small chance that it will just continue indefintiely.

[hollow garden]

true but that's not realistic

[small latch]

public static float PI_2 = 2 * Mathf.PI;

public static Vector2 GetRandomPointInsideUnitCircle() {
    float radiansCos = UnityEngine.Random.Range(0f, PI_2);
    float radiansSin = UnityEngine.Random.Range(0f, PI_2);
    return new Vector2(Mathf.Cos(radiansCos), Mathf.Sin(radiansSin));
}

public static Vector2 GetRandomPointOnUnitCircle() {
    float radians = UnityEngine.Random.Range(0f, PI_2);
    return new Vector2(Mathf.Cos(radians), Mathf.Sin(radians)).normalized;
}

Why not just this

[compact ingot]

Those have a tendency of happening though

[compact ingot]

That was my original suggestion

[hollow garden]

i mean, be my guest if you wanna use the sqrt or whatever, it works, the difference in performance isn't that large

[small latch]

didn't even see your original post oops

[hollow garden]

but just sayin my way is more efficient (although it's not that big of a difference), since it doesn't use Sin or Cos, and while it is technically not guaranteed to terminate it is just so unrealistic that it would never get a value within 2-4 tries

[small latch]

I'd personally rather take the hit with a sqrt than a while loop with a possibility of non-termination. Just doesn't make sense to me tbh.

[hollow garden]

i do get the point and it is valid technically but imo since the chance to fail n tries in a row gets very small very fast it's worth it
and also because i like how an infinite while loop with a return looks

[compact ingot]

Could guard the random sampling with an iteration limit that returns vector2.zero if it ever triggers

would be valid and equally uniform if the limit produces an expected value for a trigger > the error for uniformity

Could also use a fast sqrt and accept the error

[hollow garden]

i guess

[compact ingot]

or use an approximation function derived with some machine learning

[hollow garden]

i mean this is getting a bit ridiculous

[compact ingot]

But fun

[hollow garden]
