[sinful fossil]

Oh interesting, is that free?

[floral flume]

No, both are paid programs

[sinful fossil]

Oh ok, would you happen to know any free ones?

[floral flume]

althoughhh... there may be an alt to spine2d

dragonbones

[sinful fossil]

Oh wait are these separate programs? I was looking for something that runs in my code

[floral flume]

correct, they are separate programs

[sinful fossil]

Oh ok I see, thank you for the help but I will try to make it myself then!

[floral flume]

I suppose runtime atlasing would be useful for programs like Scribblenauts

or a program where you draw the sprites and operate on them live

[sinful fossil]

I am just doing the atlasing once at the start of the game, this is for modding purposes

So people can just drag and drop textures and the program will register them

[floral flume]

yeah that's quite a significant task -- good luck

meanwhile, trying to make this render feature use the new RThandles for blitting is crashing my editor because I'm not cleaning up somewhere even though they say "oh it doesn't need to be cleaned up!" and running out of memory

[sinful fossil]

rip

what is RThandles

and blitting? I have heard of blitting but not really sure what it is

[floral flume]

RTHandles are an abstraction of render textures

blitting is a GPU operation to "process" a source texture to a destination texture

the "process" can be as simple as a straight copy from one image buffer to another, or it could render the source image buffer through a material/shader onto the destination buffer

often used for post processing effects

I use it to emulate crappy television signals

[sinful fossil]

ohhh i see, that makes perfect sense

[floral flume]

an image effect works by "grabbing the viewport image from the GPU into a buffer" and then the buffer can be assigned as a texture to a shader/material which is then re-rendered over a full-screen rectangle using that material

[sinful fossil]

@floral flume do you think that making a texture atlas that is just a long rectangle of textures is bad?

I can do it a better way but that would be way easier

[floral flume]

I think it's probably OK, and if it gets too long you could possibly segment it into multiple files

so have multiple atlases if you have a lot of them

do this for now, at least you get off the ground and have something usable until you get something nicer later

[sinful fossil]

It will have to be the same file since this is being used as the albedo on a material

[floral flume]

heck go with it anyways

maybe it's not even a problem

[sinful fossil]

ok cool, yeah I will definity look into making it more efficient

[floral flume]

follow the golden rule of optimization: "don't"

[sinful fossil]

LMAO I believe in that rule whole heartly

[floral flume]

Quite often the optimizations we struggle to create don't even help, which is why profilers are a thing

the profiler will say: "80% of your CPU is being spent on 20% of your code"

[sinful fossil]

oh, does the free version of unity have that?

oh it does nvm

[floral flume]

uuuu I dunno if I should have some sort of static directory of RTHandles that I want to pass between multiple render features in an effects chain in a render pipelineeeeee

this sounds very hacky and bad

[sinful fossil]

i got no clue

[sinful fossil]

so hey I am going to now "paste" the textures onto the atlas, do you know the best method I can use to make this work simply?

[floral flume]

heh, you asked "best" method. But in the end it comes down to costs and benefits.

Like, the GPU could probably be tasked to do it really quickly but then it is a lot to deal with

[sinful fossil]

best and simple is what I said, I dont need the MOST OPTIMAL

[thick cipher]

what AI framework would be best suited for a simulation in which npcs start building houses and fulfill their needs like sleeping eating etc. I thought about mixing GOAP and Utility AI

[floral flume]

well... I'm guessing that the atlas will be immutable once it is loaded and stitched together

[sinful fossil]

indeed

[floral flume]

and you're gonna need some way of storing the rect coords as well as unique identifiers

like a dictionary

[sinful fossil]

I recommend asking that question again in a few minutes cause our convo might drown it out

[thick cipher]

will do haha

[sinful fossil]

I have that covered

[sinful fossil]

sorry, actually I might be able to make it a thread let me try

[floral flume]

hmmm... skyrim, or dwarf fortress?

[sinful fossil]

Texture Bliting

[thick cipher]

more like skyrim 🤓

[sinful fossil]

are you trying to have parameters that all come together to determine what your AI will do or do you have a single action for each condition like: if tired then sleep, if hungry then eat...etc

[thick cipher]

different parameters that come together

maybe I need to do some more research myself on these topics I never dabbled in AI much and I am pretty much a beginner

[sinful fossil]

and are you wanting these ai to learn or to have a preset of behavior?

[thick cipher]

preset

[sinful fossil]

Well then I think you should try simply making a list of tasks that can be queued up when ever and run through over time. And make priories like death actions and sleep (passing out) so that they overtake the other queued tasks.

Then you can make another list of conditionals where when things happen to the ai, they run through their conditions and check if they are true or not, each condition will either lead to queueing up a task or adding to a variable that needs to pass a certain threshold and if so then queing up a task

[sinful fossil]

if you wait a sec, I can set up a tiny framework for you

[thick cipher]

you're a saint

[sinful fossil]

something that will get you started but you will do the heavvy lifting

i will make it intuitive

[thick cipher]

I just need a direction and I am thankful for every input

AI research is fun but its a topic i just started learning looking forward to it haha

[sinful fossil]

the world of ai is so AMAZING

[floral flume]

I think that people are odd creatures in that they are actually multiple competing systems, some driven by thoughts, some more driven by urges

[sinful fossil]

profound and so random lol

[floral flume]

so if I were to make a system of people I would have them possess multiple systems that track things like bodily needs and urges such as hunger/toilet/fatigue, and other systems that track things like "progress on job/need for money/need for entertainment and socialization"

and these systems would have to compete against each other to determine what needs to be done first

now this would result in people that don't plan for anything -- they would be rather childlike

[thick cipher]

its wether to unga or to bunga in the end

[sinful fossil]

just out of curiosity, do you know how virtual and override methods work?

[floral flume]

but there would be systems that govern fulfillment of purpose(unga), and then systems that govern needs of the body(bunga)

[thick cipher]

I mean there is a pyramid of needs that exists at least as a model

and the top of it is self fullfilment

[floral flume]

virtual methods exist in the parent class and may be overridden by child classes

[sinful fossil]

yes, but I was asking Michael lol

[thick cipher]

you can stop right there, I might have given a wrong impression but I know too little about a lot of things. need to learn a bit more to unterstand some fundamentals

[sinful fossil]

oh well, they are very simple and fun, do you want me to stop the framework?

[sinful fossil]

no worries if so since I am going to use this framework myself also

[thick cipher]

you can stop it ❤️

no need to do work for me which I wont even properly understand yet

[sinful fossil]

ok sure thing. I was going to give you a very brief and understandable rundown of it but I am not gonna force you. Anyway I am still gonna continue since I want this thing finished for myself

in fact, this is actually going to be something I need to do for the game I am currently working on

[thick cipher]

ill get back to you and thanks for being so helpful to strangers on the internet

[sinful fossil]

My pleasure, plus your not necessarily a stranger since you somewhat demonstrated you mentality and personality and also use the advance section on the unity discord about AI frameworks so either you are a normal programming person that's curious and wants to learn a bit or you found the most specific way of cyber manipulation and/or kidnap

[wispy epoch]

Making a panel that comes up when you press a button that shows a weapon's stats depending on which weapon's button you pressed. I need to change the weapon sprite that pops up in the panel to whatever sprite is linked to the weapon. Problem i have is there are 20 weapons. Is there a better way to do this than declaring 20 public sprite variables and inputting each sprite? Maybe there is a way to get the sprite from the image of the child and just change the sprite to equal that? Not sure how to implement that but it might be cleaner, looking for good performance out of it since it needs to do a lot of operations fast when bringing up the panel for the weapon

[floral flume]

mecanim is able to record the sprite index of a sprite renderer, I think.. or you could use a List<Sprite> instead of separate vars

[sly grove]

Learn to use arrays/lists

[coral echo]

Is anyone familiar with the PID Controller being used in the Unity hover racer project? How do I expose the public properties of that script so I can fine tune it in the inspector? It doesn't inherit from Monobehavior

[wispy epoch]

SOrry i didnt explain properly but thats currenty what Im using. I was wondering if there was a more advanced way that was cleaner than having to drag and drop 20 weapon prefabs or sprites into an array in the editor

[sinful fossil]

Hey does anyone know how to turn off repeating texture using graphics.blit()? The image wrap mode is where the problem is but there is no option for no wraping.... How do I do that?

[sly grove]

Resources.LoadAll?

[queen gulch]

Doesn't that work in the runtime?

[queen gulch]

I think there's an option to create a sprite altas with sprites in a fold, but I'm still dragging eveything

[native beacon]

Why not save a reference to the correct sprite wherever you're saving the stats for each image?

[midnight violet]

What does it inherit from?

[wispy epoch]

im not saving the stats for each weapon anywhere. Trying to figure out scriptable objects for that rn

[jovial totem]

ok this is a weird problem. I have a float[,], and I need to downsample it to a smaller array, as if it is an image

what is the easiest way to do that

should I like, take every other point and average it with its neighbors

it's for an LOD map so it's fine if it looks lumpy

[native beacon]

Well, when you make your SOs you can stick the image reference there too.

[regal olive]

is there an implementation for trng? or is Math.Random() true Random

i found RNGCryptoServiceProvider. i am not able to test it rn but is it fast?

[coral echo]

It didn't inherit from anything. But I got it expose as a scriptable object now, works just fine. Just need to figure out how to tune it for best results

[devout hare]

You can't generate true randomness without specialized hardware

Why do you need it?

[regal olive]

signature algorithms and encryption

[midnight violet]

Not sure if this is advanced, but lets try it here. I am loading a chat collection from a backend and then getting parts out of it to not overload unity UI, basically lazy loading. Attached is my approach, which is 'working' besides the positioning, just ignore the sibling part. But do you have any suggestion or maybe idea, how to make it more dynamic? Not sure if this is the best approach so far: https://pastebin.com/B7evNzCz

[winter yacht]

Sounds a bit like The Sims

[midnight vale]

Hi there. Just a quick question. If I wanted to add a pre-build process to my project how would I do that? For example if I have a separate command-line based exe file (stored outside the unity project) that builds and adds some important data files into my Unity project's resource folder, is there a way for me to automatically run that as a pre-process when I press play or build the Unity project? Any help would be appreciated. Thanks.

Sorry if I've posted in the wrong section but I didn't know where else to ask this

[regal olive]

my friend copied code from the internet and it comes up and he has a compiler error how to help him?

or he will give up and not submit anything and fail

[flat marsh]

we can read multiple channels you know

stop posting everywhere

[stone yarrow]

(Moved to General)

[regal olive]

its legit he is in my situation

if we dont submit tomorrow we get 50 percent off

he has copied code but it comes up with compiler error

[flat marsh]

he got muted, dont expect a response

[sly grove]

BTW you can just select them all and drop them all at once. You don't have to do them one by one.

[devout orbit]

Does anyone know how to resolve this issue?
Using .net core and unity webrequest can't find a good answer on google

[midnight violet]

well your SSL certificate is either wrong, or not correctly configured or you ar eusing https:// where no ssl is present at all

[devout orbit]

I'm just running it local and It tell me I already have a developer certificate.
The API is using Https, found a work around tho.

    public class AcceptAllCertificates : CertificateHandler
    {
        protected override bool ValidateCertificate(byte[] certificateData)
        {
            return true; 
        }
    }```

When using a real server you it shouldn't be the case anyone more

[woven kettle]

hey

how to deal with this issue?

is it safe to turn it off ?

[flint sage]

Get the right version is better

Validation is there for a reason, you might get runtime/compilation errors otherwise

[woven kettle]

how do i get the right version?
that is a package that I've installed from github

not what I should be looking for

[flint sage]

Idk, download it from nuget or something

[woven kettle]

well it's not there, but if it's saying that a higher version is already running , maybe I could just exclude that folder from the package ?

[flint sage]

Sure you can override assembly references if you change the package

Still, it'll complain about conflicts

So you need to decide which version to use

[woven kettle]

I can use the higher version ( version 5.0.0.0 ) but how do I override the version ?, i have never modified anything in the package folder before

[flint sage]

Either recompile the DLL to depend on that new version (or remove version dependency all together) or disable validation for that dll (or project)

[regal flax]

I'm trying to make a car accelerate using an animation curve how can I do that. This is the current script

[midnight violet]

Animation curve uses the evaluate function to get the value at a specific time point

https://docs.unity3d.com/ScriptReference/AnimationCurve.Evaluate.html

[regal flax]

and the time point how can I find that cause that's what I'm trying to find cause that doesn't give me a code example to understand

[midnight violet]

Depends on your curve, did you play around with it? the time is basically the length of the curve. So whatever value you put in as time will return the value at that timespot

[regal flax]

I put it till 5 end

[midnight violet]

so your time is from 0-5. Thats your timespan you can work with

[regal flax]

ok so I do animation.lenght?

[midnight violet]

I think that returns your key count, so yes, get the latest key, get its time, then you know your timespan

[regal flax]

animationcurve

[midnight violet]

https://answers.unity.com/questions/326824/animationcurve-how-can-i-know-when-the-end-of-the.html

thats an example

[regal flax]

ok so now do I do anything else

[midnight violet]

Depends on what you want to do with that curve 😄

[regal flax]

to accelerate the car

[formal anchor]

Hi, I'm having a logical problem. I'm thinking about implementing a placement system in my 2d game, basically a grid for all placed objects on the map. The problem is combining this with procedural generation: Using start for an object to place itself on the grid wouldn't work due to the procedural generation all being in one frame, but awake comes in handy I guess (?), but how should I go about the destroy function? Because OnDestroy() is getting called too late, so clearing the object from the grid happens too slow for a switch of objects for an example, the old object tries to get cleared, but the new object is already trying to write over the grid, but the old one is still in the way.
I hope you get what I mean, I really don't know how I should be implementing it, I got a few different options, but I'd like to hear your ideas :)

[midnight violet]

thats not a good description. I mean you head something in mind using the curve, so what was it

[regal flax]

I want the curve for the speed of the car to speed up

[midnight violet]

So you want to accelerate the faster it goes the faster it will accelerate or what exactly?

[regal flax]

yes I want the car to go faster

[cloud crag]

Build failed. It works in gamemode. Help please?

[regal flax]

just like you said

[regal flax]

you have input problems

[midnight violet]

Well than accelerate it from 0 - 5 with the value of your animationcurve. So the first value should not be 0

[cloud crag]

I think Assembly references are the problem

[regal flax]

ok so I make the power being the number * the motor power

[midnight violet]

To be honest thats something you should prototype on your own now. Theorising everything wont work hear. Try out and see what the result is 🙂

[regal flax]

ok so it works but now I need to find a way to make it that when your not giving inputs it brakes

[flat marsh]

editor scripts need to be in a folder called Editor

[cloud crag]

Thank you!

[regal flax]

ok so it worked but then when I let go it wouldn't start slowing down

[midnight violet]

Go find out yourself 😄 I can't do the thinking for you

If you tried something, com eback, but first, this is not advanced, so lets head to #archived-code-general and second fiddle around a bit so we have a base to talk about

[wispy epoch]

For a series of scriptable objects im using, does it make more sense to store the level the player has upgraded their item to inside the scriptable object and edit the contents of the scriptable object when leveling up? Or does it make more sense to leave that data in Playfab API and make api calls to it when the user views the data or changes it?

Currently rocking it with Json files uploaded in Playfab but this seems inefficient and potentially costly and buggy if players spam between inspecting different weapons. I just want to make sure the player upgrades are safe though, and tied to an account so if something happens or they uninstall, they dont lose all the levels they dumped into each weapon. Would data changing for a scriptable object even work for this and would it save the data to the account somehow if the user changes devices or uninstalls?

[flat marsh]

You can not use script able objects for save data in a build

[regal olive]

"can't build when scripts are compiling" what is this?

[fresh salmon]

Wait for the compiler to finish working before making a build

Usually a spinner bottom-right indicates a compilation is in progress.

[regal olive]

ok thanks

"'texture 2D' does not contain a a definition for alphaIsTransparency"

does anyone know a way to export a unity game or something like that without doing the build thing?

[thin mesa]

you have to build your game for it to be playable. like that's literally the entire point of building it.

[regal olive]

then why It aint building then

[fleet lion]

It's like asking how you can run code without compiling, you need to do it

[regal olive]

why It works perfectly fine when I play it normally on the thing

but now when I export it it says there are errors?

[fleet lion]

What error are you getting, ill take a look

[sly grove]

this isn't really the right channel for it

[fleet lion]

Was thinking about that, where could he best post this if i may ask?

[sly grove]

#💻┃unity-talk probably

[regal olive]

"texture 2d does not contain a definition for alphaIsTransparency"

[grave sandal]

hi, how are you guys ? .. i have a short one .. it's more an opinion thing .. what is the most common thing u guys use interfaces for?

[fleet lion]

adhering to unity's constraints on components and making them compatible with the engine. For making own interfaces generally things I know I want to reuse later in several scripts or objects, etc.

[floral flume]

Is it a bad thing that I routinely find it faster to solve problems caused by a lack of documentation or Unity bugs by hacking together my own solutions and workarounds rather than going through the official routes?

[fleet lion]

yes and no. Unity changes a lot and isn't always up to date with documentation, but this can bite you later on, especially if things end up updating or if it's a long term project. Best be careful with hacking things together

With that said, sometimes you just need something to work and can look into fixing it properly later 🙂

[floral flume]

yeah, my problem is it is a long term project but the problems i run into leave me dead in the water until a fix is made (either by me or Unity pesonnel)

and I kind of don't feel like sharing around my hacky crap, especially since most of the time it is odd edge-case scenario stuff

[fleet lion]

Make sure not to go against Engine constraints, OOP constraints and generally you should be okido

And don't build on hacky implementations or spaghetti because you will probably need to do it properly at some point!

[floral flume]

uh, last time I went up against an engine constraint it was back when Apple killed off OpenGL for its metal graphics, essentially killing compute shaders on their platforms (at the time)

[fleet lion]

that's my rule at least. Quick hack to test things out, or leave it as-is for a bit to improve later. = okay,
hack something together, pretend it's fine and expand on it = please no

[floral flume]

uh, my problem is that I hack together things that are needed at the fundamental (fun and mental) level

[fleet lion]

haha orriight, well i mean if you dont want to share it here you can dm me a bit about your problem and i could take a look (can't guarantee im any help with it though, ill probably reply tomorrow as it's nighttime for me)

[floral flume]

thank you for your offer - I'll take it up some time in the future

[fleet lion]

sure thing, best of luck with this!

[floral flume]

well if someone needs to know how to make RTHandles shareable between postprocessing Renderer Features in a URP pipeline hit me up because I don't wanna write a long forum post documenting the solution to a niche issue

idk why my tilemap is getting ignored by the raycast

any help is greatly appreciated

I've read that Raycasts only look for gameObjects in specific LayerMasks

Has anyone had trouble with deriving from HashSet<> and implementing ISerializeCallbackReciver?
For me, when I try to Add in OnAfterDeserialize() I get a DivideByZeroException...

I thought to take a peek at the HashSet code to see what might be up, but I am not seeing any divides at all in AddIfNotPresent which is where the exception comes from according to the log

[hot geyser]

Hello everyone, I am wondering if any person has an idea of how to arrange a number of objects in a straight line, but from the transform origin must be the center of the objects? Such as below. The number of game objects can range from 3 to 5, to 10. Many thanks for your help and sorry for my english, I hope I have explained clearly.

[urban warren]

You just take the space you want between the center of each object then multiply by the number of objects, then divide by two. Then you simply subtract the result from the axis of the start position

Then of course iterate over the objects setting there position to be the start position + the offset per object

[wooden cedar]

Sounds like someone's course work assignment :P

[maiden frost]

Is there a way to use math formula to generate animation curves. I want to enter a formula and it will generate animation curve that I can reference in script.

I am making a theremin and synthesizing audio. I want to exponentially increase frequency, I can do it in code but I was wondering if I can use Animation Curves. Like insert a math formula and whenever I wanted a value using evaluate().

The main reason I want to do this is because someone told me this is a faster way rather than calculating frequency along with soundwave in update.

[regal olive]

y=x^3

or

y=x^2

[maiden frost]

Yeah, but how do I make that into AnimationCurve?

[novel wing]

evaluate it at some range of x

oh wait now i see what you mean

No I still don't get it actually

If you wish to evaluate a formula for some value then insert that value in the formula and calculate it

If you're looking for some formula parser then it will be a lot more complicated

[maiden frost]

How/where do I enter a formula to get an equivalent curve in anim curve?

[novel wing]

An animation curve isn't a formula. It's a series of points that are evaluated in succession

Look up Bézier curves

It sounds like you could get away with making a cubic one in your case.

[maiden frost]

I am doing that in code but someone told me it would be easier if you saved that formula as a curve and use evaluate to simply look up the value

[novel wing]

Well in this case you don't. You can't construct an animation curve out of some formula simply because the animation curve is based on the Bézier Curve formula.

If you wish to make a graph of your formula on the other hand, you would have to sample for some range of X and draw it on a texture

[lavish plinth]

I have no idea how to make a payload kart that turns on ramps. i tried multiple solutions with no results. is there any who can help me out?
https://pastebin.com/miWH8yDY

[maiden frost]

That's kinda bummer. Thanks for the help.

[novel wing]

If you're performance aware you could make a lookup table from your AnimationCurve. So you won't have to constantly evalute it.

But yeah, not sure what you need exactly

It's kinda a complex problem and I'm not too familiar with sound processing

[maiden frost]

That's exactly what I wanted to do. Enter a formula to make a curve and use the curve as look up table. But I guess that's not possible.
Anyway, thanks for the help

This is the formula and y_lin is float value between 0 and 1. I wanted to reduce calculation every frame

[novel wing]

In this case can't you just make a function in code to calculate this for you? Or are you also looking for something like a string input field in the editor where you can input any formula and see what it spits out?

[maiden frost]

I guess that's me only plan now

[novel wing]

Isn't it just cs private double GetThatValue(float x) { return 440.0 * System.Math.Pow(2, 120.0 * x - 53.0 / 12.0); }?

[maiden frost]

Yup

[novel wing]

Then I don't think you should worry about performance, this will most likely be very fast

[maiden turtle]

Has anyone done portable float binary serialization?

I'm confused as to how to handle endianness

or should I just handle it manually, by float definition

[junior lynx]

anyone familiar with json api in unity

using web request

[midnight violet]

Whats your issue

[tough tulip]

you can do it manually too by float definition.
or you could use a struct with same field offset for float and int, then use bitshifting 4 times on int to get the binary data. dw about performance. structs are very fast and better than using BitConverter

[maiden turtle]

so are you saying that float always has the same endianness as int?

but yeah, the definition is like my only idea

it's kind of annoying, but I can't think of anything else

[humble pasture]

Since 3 Days i try to use sql on android but why is this shit not working?

on pc its working perfect but on android it says "DLL sqlite3 not found" WHYYYY

[tough tulip]

float stores data as
sign-exponent-mantissa
1-8-23 bits respectively

each of them follows big endian where the most significant bit is placed at lower memory address

but in practice it might also change based on the hardware. normally you should code based on the endianess of the hardware architecture, which you can determine at runtime using BitConverter class, theres a property to determine it.
BitConverter.IsBigEndian or something like that

[tough tulip]

this approach is independent of the Endianess

[humble pasture]

WHY i cannot fix that T.T

[junior lynx]

Hello @midnight violet i did a for loop on objects in the api i got 20 outputs in the console but how do I get them shown in text game objects inside the game

[flat marsh]

the dll is properly setup to work with android?

[humble pasture]

but it doesnt work on andoird

ys

it

is

i have 3 types x64 x86 and ARm

but it doesnt work :c

[humble pasture]

are you gone? :/

[flat marsh]

its been like 3 minutes...

they have the proper checkboxes set?

[tough tulip]

show your code

also whats the file extension of the plugin? android expects .so instead of dll

[midnight violet]

Okay, i revert my dont mention me, I see I answered you. But still, this is not advanced code question. #💻┃code-beginner or #archived-code-general is your place

[humble pasture]

yeah it is .so

code is coming

this is the problem method

and this is the newest error

[fresh salmon]

Note that the error message mentions libsqlite.so while you have libsqliteX.so, this might be an issue?

[humble pasture]

i had downloaded witheout the x but nothing changed

[junior lynx]

Chill ok I'll ask there if you know please help me with that

[humble pasture]

i downloaded the normal one again but error is still there

@fresh salmon

[fresh salmon]

I'm not experienced with mobile, that was a guess

[humble pasture]

oh

Seems like it can't find a lib named sqlite3, can you download something like that?

[humble pasture]

it is in the folder

[fresh salmon]

Or maybe it's bundled within libsqlite idk

[tough tulip]

did you by any chance rename the so file? you shouldn't rename the so files normally after its compiled. how are you loading the so file. show the code which does dllimport.

your dll import name shouldn't include .so aswell. just the file name without extension

[humble pasture]

ist just downloaded sgliter from the assets store lol

WAIT

i tested it in another program and there its running :o

nervermind

the problem is not the importing the problem is soemwhere in the code ```cs
List<Device> devices = new List<Device>();

    IDbConnection connection = new SqliteConnection(dbName);
    connection.Open();

    string where = "";
    if (id != null) where = " WHERE `Geraete_UD`= '" + id + "'";
    string sql = "SELECT Geraete_ID, Geraete_Typ, Geraete_Hersteller, Geraete_Bezeichnung FROM `Geraete`" + where + ";";

    IDbCommand command = connection.CreateCommand();
    command.CommandText = sql;
    IDataReader reader = command.ExecuteReader();


    while (reader.Read())
    {
        string ID = reader.GetValue(0).ToString();
        var type_ = reader.GetValue(1);
        string producer = reader.GetValue(2).ToString();
        string name = reader.GetValue(3).ToString();

        string type;
        if (type_ == null) type = "";
        else type = type_.ToString();

        Device device = new Device(ID, type, producer, name);
        devices.Add(device);
    }

This Error comes from this line of code but whyYY????

Can I ask for people's opinion on the age-old LINQ debate? Take this use-case, for example: https://pastebin.com/s1JfHgXq

Assume that allContainers has been populated with entries and their MyConfig properties have been assigned valid values.

Which is "better": BuildListWithLinq() or BuildListWithoutLinq()?

[fossil bloom]

Hello, I have a recurring problem when writing code which needs to assign slightly different values to some variables based on some input. I usually do it via switches/if statements.

Often, I need to write functions in which a translation of some kind needs to be mapped to offsets for some coordinates. E.G. if translation == (1, 1), then offset1 = (-1, -1), offset2 (-1, 0).

I always know the amount of different combinations the translation can have as well as the offset values for each combination. The translation and offset values, however, change based on the context they need to be implemented for.
The problem I have is expressing this logic cleanly via code for all combinations. Ideally I would map all translation values to a switch with constant struct values and set offset values per case. Clean and simple. However, switches don't support const structs outside primitives like int, float, string, etc.

For some functions I have mapped the struct values to a single integer since a const int can be used in switches. E.G translation = (1, 1), (1, 0), (0, 1), (0, 0), then state_value = 0, 1, 2, 3 for each accordingly.
With this solution I can then declare an enum or many named const integers for each case to make the code more readable by making the translation mapping to an integer which regulates the switch state easier to understand. Though this solution still feels hacky and dirty.

Worst case I had done to express this type of logic was to do it with if statements. It leads to a lot of nesting and a mountain of code if doing ifs per single field value. E.G if (translation.x == -1) {if (translation.y == -1)}.
Specially when the data combinations increase in amount as well as field count for a struct.

Lastly, a chain of if else statements for testing every combination remains.

My question is, is there another way which is cleaner that I may have overlooked?

[regal olive]

Hey there. I'm having a problem where I'm using a shader to simulate a black hole distortion and rendering the image from a camera to a render texture. I'm instantiating various black holes during the game but the distorted image is updating to the most recent black hole placed instead of each of them render to it's own texture

is there a way to solve this?

if you need more insight, I can try to explain better

[maiden turtle]

I had a similar problem with a button on the experimental SVG image on a world space canvas. I think it's multiple layers of logic incompatible with each other, perhaps lazily programmed

[hardy sentinel]

what code are you using? you should pass the already distorted texture to the next BlackHoleSimulation shader

so, something like:

var texture = GetRawTextureFromSceneAsCameraWouldRenderIt(); // should return a copy
foreach (var blackHole in blackHoles) { Graphics.Blit(texture, blackHole.material); }
texture.Apply();

[hardy sentinel]

you can use switch (asdf) { case MyStruct m when m.x == 1 : { break; }
Still, some better implementation would be to math the shit out of it 😄

[fossil bloom]

@hardy sentinel thanks, wasn't aware of pattern matching before.

[sly grove]

The best way to do this is:

static readonly Vector2Int[] directions = new Vector2Int[] { Vector2Int.one, Vector2Int.right, Vector2Int.up, Vector2Int.zero}

Vector2Int GetDirection(int state) {
  return directions[state];
}```

switch statement is way too much code and less performant too

i need help someone
any one have idea how to read keys if game window is out of focus i was taring this Keyboard.IsKeyDown(Key.Down) but error CS0103: The name 'Key' does not exist in the current context

[spare pond]

Zenject question. How to inject class but keep the same reference across gameobject?

For example:

Hierarchy:

goA
childA

goA(1)
childA

That's two identical gameobjects (duplicates). Root and child obejcts has same inject reference. How to make 1 inject class for each gameobejct and let reference it to root and child?

[sage radish]

You need a GameObjectContext on those root game objects. Then you can put an installer on each root game object that binds a shared instance for that context.

[spare pond]

Hm, let met try. Saw about gameobjectContext but thought i can do this without somehow

[sage radish]

If these are spawned at runtime, you can spawn them with an argument to be injected

[spare pond]

this GO's placed manually

Yea, thats what i wanted, thanks. Feels like ScriptableInstaller will be good for this task (for example if i have integer that will be different on each object)

[tough tulip]

this will not even work if window is focused.
Keyboard.current[Key.Down].wasPressedThisFrame is the correct syntax.
check for the property name in your IDE once, might be slightly diff than what I typed but you get the idea

[scenic marlin]

Hey does any of you know if you can get the velocity of a gameobject in a direction that is not x,y,z ?? but between them?

[sly grove]

huh?

Can you elaborate on what you mean

[thin mesa]

i'm curious how you expect direction to be expressed without a Vector3

[eternal frigate]

a rigidbody component gives you the velocity on y axis, but what I need is the velocity in transform.up when the object is rotated xD

[sly grove]

wat

What does "the velocity in transform.up" mean?

[thin mesa]

this sounds like a whole lotta XY Problem since none of it really makes any sense https://xyproblem.info/

[sly grove]

Are you asking for how to get the velocity expressed in the object's local space instead of world space?

that would be cs transform.InverseTransformDirection(worldSpaceVelocity)

[eternal frigate]

Thank you ❤️ sorry that I was so unclear, I'm too tired xD

[undone coral]

haven't we discussed this?

or was that someone else?

use input system, which can listen to events while in the background

[scenic marlin]

@undone coral i can t find it so probably not

im trying now to get image from copy buffer to unity and i cant get it to work and find something usefull
probably i will end up with opentk and writing some sketchy rendering engine

[undone coral]

what is your objective?

what is the game/app

[scenic marlin]

just a tool for a game im playing auto copy

something line 3d map

[undone coral]

Keyboard.current... in Input System can directly replace your Input calls and supports background listening provided you check the right box

okay

[scenic marlin]

where

[undone coral]

you can read through the input system "how to migrate from Input" documentation

then search "input system background" in google and it will show you the checkbox

however, i don't know if specifically the keyboard is supported

because it would be a security issue if any app in windows could read your keyboard

[undone coral]

try this approach - https://www.youtube.com/watch?v=FpvJAG6R99k

[undone coral]

use tuples of the form

[scenic marlin]

now only getting image from clipboard

[undone coral]

foreach (var (transformCompare, offset) in new[] {
  // transformCompare, offset
  ( -1               , new Vector3(-1,1,0)),
  ( 0                , new Vector3(0,0,0)),
  ( 1,               , new Vector3(0,5,0))
}) {
 if (myValue.x < transformCompare) {
  myOffset = offset;
  break;
 }

@fossil bloom does this make sense?

[wispy epoch]

Hey im working on equipping weapons in my game. The functionality is there but I'd like the player to be able to see what weapons are equipped when viewing the panel of guns with a little check mark or something. The only way i can think of to do this would be to have a game object in each weapon's child panel called "GunNameHereEquipIndicator" and say find object in hierarchy with name = gunName + "EquipIndicator"; Which is inefficient on its own, but worse, Id have to deactivate all the rest of the object check marks too. Is there a much better way to do this that doesnt seem so cluttered and inefficient.

I just want the gun that i have equipped to have some indication of it and remove that indication otherwise. For clarification i have one panel with all the weapons on it and you can click on each one to bring up an inspection screen where u can upgrade and equip it. Id like the equipped gun to indicate its equipped on the panel with all the weapons on it

[whole badge]

if im understanding correctly it sounds like the checkmark should be a feature of whatever component you're using to render the weapon icon

which is to say that your weapon thumbnail, icon, name, etc, should all be under the control of some component you write / have written

that's how i would do it

that way the component can have a reference to the checkmark set outside of runtime

[wispy epoch]

Sorry not sure I follow. So like i could have an image component with the checkmark as a child of each of the gun panels in the first pic, but I dont know a more efficient solution of checking which is the equipped one than looping through each, checking if it is equipped, and if it is set the checkmark active. (and if not set inactive)

[whole badge]

that's fine

[wispy epoch]

It seems very inefficient and id have to keep an array of all the panel checkboxes in my editor/code which is already bulky enough

[whole badge]

the slow part is the Find()

the rest is just necessary, you can't know what's equipped without going to the player and asking

but you can remove the Find by storing the reference to the checkmark outside of runtime

[lone raptor]

How hard would it be to make a rending thing where I could have an object moving around the map and working like a lidar, creating a dot cloud like real life lidars do? I am thinking of a script that uses raycasts in specific FOV, for each point it hits it creates a vertex which in shader can be enlarged and rendered as a dot, additionally that list of vertices could be stored in a ring buffer. Though firing hundreds of raycasts per frame could be kind of expensive, not including the vertex creation part. I want a result just like in the image I attached

[wispy epoch]

Did u mean checkmarks plural because I can't figure out how to have one checkmark that just places itself on whichever ibject in hierarchy i want

[sly grove]

Ideally you'd do it in a compute shader (which runs on the GPU). It's basically raytracing, just with a smaller number of rays and different ray sources.

[whole badge]

are u using like a bespoke ui for all the weapons?

[lone raptor]

I don't have much experience with shading, especially compute shaders, any guide where I could start with that?

[sly grove]

each one of these "slots" should have a copy of a "WeaponSlot" script on it. And that script should handle everything within that slot: the name shown, the gun model shown, and anything else like checkmarks etc..

[lone raptor]

Actually nvm, I forgot I have google

[whole badge]

if this is the case i'd recommend changing to use like a reusable ui component

that's the way i do things with much of my UI

and then i'll write my UI component

you'll throw the references to your desired name, icon, and checkmark into there

and that lets you use tthem all in a generic way

[wispy epoch]

Currently its all just buttons with a sprite for each weapon and then the button calls the function to bring up the panel with the stats of the weapon with an index supplied to it

[sly grove]

time to refactor everything!

[whole badge]

you can half-ass it though

if you don't feel like refactoring

write a component that stores the checkmark reference

attach it to each instance of your weapon button

and have it control the checkmark for that weapon index

it's not like nice but it'll work just fine

[wispy epoch]

if i am understanding correctly i feel like redoing it all into what @sly grove recommended of each button getting its own script would be just as involved as this writing a component solution. Only thing stopping me from that idea is i still cant conceptualize how to update each equip "checkmark" other than in an update function which i haven't really used at all in my game yet. If i change it on start and on equipment change would that work even though the game objects are inactive at the time of setting?

[whole badge]

so uhhh

firstly

you wanna be conceptualizing the ui here as like

individual instances of a prefab

like any kind of prefab object you expose references through the inspector like the image you want to use and the name of the weapon

and then u can drag and drop them into an objeect to set that all up by hand whhich is similar to what you've already done anyway

those objects are going to run Start() when they get instantiated into the world and that's where you'd do your checking and updating of the check mark

that will be enough i think

and then taking that further would be removing the manual set-up entirely and just instantiating the whole objectset through code but hey that's not strictly necessary here

@sly grove i'm not sure if im explaining this effectively

[wispy epoch]

I see how that would be more effective but this took me a good 3 days to build out and my brain is starting to get fried so i dont know how much im willing to rework here for the equipped indicator. My question would be, if i make the checkmark on each of the buttons and then make a new script that i make as a component for each button, is there a way to call a function in each of them at the same time to do a simple check if (primaryWeapon.gunName + "indicator" == checkmark.gameObject.name) { checkmark.setactive(true) }

[gray pulsar]

You should have some kind of event system with an event like OnEquippedWeaponChanged. When that event triggers, each WeaponSlot will receive a callback and run a method to update its own checkmark. The OnEquippedWeaponChanged event can pass in the newly equipped weapon to that method, so the WeaponSlot can just check whether the new weapon is the same as its weapon. If it is, it sets its checkmark active. If not, it sets its checkmark inactive.

(This is in response to "updating everything in Update()")

[whole badge]

ultimately your solution with Find() will work, it just won't be efficient, as you said

you can still do it if you like, and you can probably minimize the impact if you're only calling the find one time for each object (8 objects -> 8 calls)

and like, setting it up so it only calls once can be done a number of ways and is really up to you

you can leverage start()

or you can write a component that does it

or you can make methods and have something call them

[wispy epoch]

Im thinking i may just bite the bullet with another big array of 20 game objects each being the Text field for equip indicator on each weapon in the panel. Then on start and on equip change i call a function that loops through each one and if the name of the text field equals what i want i set it to say "1" or "2" for either slot, and blank if not equipped in either slot. This seems much more efficient that find, simple enough that i know what im doing, and just unfortunately not very cleanm especially for adding new weapons

[whole badge]

hmm

i think that if you were to bite a bullet you'd want to be biting the one that's all about making the UI generic

it'll save you time

[wispy epoch]

which solution are u referring to lol. sorry there were a lot of options

[whole badge]

essentially this:

• make your UI into prefabs that serve one purpose
• write small controllers for each UI prefab
• expose any references that change things

instantiate those prefabs at runtime and they kinda do their thing in a way where noone else needs to be concerned with their internal structure

[wispy epoch]

by instantiate them though, do you mean i have to set them via code on start, rather than have the prefabs lined up how i want in the hierarchy previously

[whole badge]

yes

actually you can have them lined up by hand too,

they'll still run Start() and do their thing at the moment they get loaded into the world

working example:

these are all the same object

[wispy epoch]

so do i still need some kind of event handler to check them again each time equipment is changed? Im not really sure how to make an event with event system. Ive been mostly using input system

[whole badge]

only i'm exposing a property here

[whole badge]

when i use this pattern i often find it advantageous to destroy ui elements when i no longer need to show them on the screen.

and if you do the same thinng then you can create them each time you need them, which means they'll run start() at that moment and you put your stuff in there.

[wispy epoch]

ah so destroy them all and when reinstantiated they run a start function

[whole badge]

that's one way, yea

alternatively, if you have them always present you can i guess try to keep references to them all so that you can run some kind of checking method but that's more complex i think

this is kinda all structural and it's really up to how you wanna do it but the important part is you have some specific moment where you make them check

[wispy epoch]

makes sense but idk if its feasible to line them all up in the horizontal layout groups i have them in through code. it was very complicated with the settings since im doing some weird stuff for phones with a notch

[whole badge]

well you could also put all those thumbnails inside another prefab and then instantiate that prefab

they will all run start() just the same

[wispy epoch]

I see. Thank u for the pointers. I wrote a couple options down to look at later and see which i will go with. I need to get a break for now. Thank u tho

When using ASMDEFs, if I just leave Any Platform checked for all of them, that shouldn't affect the compilation time right? Or will narrowing down the Platforms section actually decrease compilation time?

Hi,
I was looking at the newer mesh apis, and I want to set the vertex colors with https://docs.unity3d.com/ScriptReference/Mesh.SetVertexBufferData.html
I don't want to adjust any of the other properties of the mesh.
In the example in the docs, it only shows how to set full descriptors and full data for the mesh.

Am I right with the assumption that if I only set the data for the specified stream, it should work? because every Descriptor in the VertexAttributeDescriptors array seems to have a dedicated stream index?

also do I need to check for the VertexAttributeFormat of the colors attribute separately (which I assume is the .dimension property) and take some conversion steps when it is not VertexAttributeFormat.Float32 or is that automatically handled? In the example, the format for the tangent is UNorm8 but a regular Color32 value is used in the struct so I guess it should be fine?

here is the code I have, haven't run tests yets:

private void UploadColorsToMesh(Mesh mesh, Color[] vertexColors, bool skipIndicesValidation = true)
        {
            int stream = 0;
            MeshUpdateFlags updateFlags = MeshUpdateFlags.DontResetBoneBounds | MeshUpdateFlags.DontRecalculateBounds;
            if (skipIndicesValidation)
            {
                updateFlags |= MeshUpdateFlags.DontValidateIndices;
            }
            int numberOfAttributes = mesh.GetVertexAttributes(attributeDescriptorsTemp);
            for (int i = 0; i < numberOfAttributes; i++)
            {
                var attribute = attributeDescriptorsTemp[i];
                if (attribute.attribute == VertexAttribute.Color)
                {
                    stream = attribute.stream;
                    break;
                }
            }
            mesh.SetVertexBufferData(vertexColors, 0, 0, vertexColors.Length, stream, updateFlags);
        }

there is an extra folder for android so i think so

[timber flame]

There are some voxels, they are combined into one mesh. I would like to remove repeated vertices in that mesh.
The common and efficient way is to define a 3d array and keep indices of vertices inside? or define a dictionary but accessing is not optimal in a dictionary

[umbral trail]

Some kind of spatial hash like quantising or an octree, and better to not add vertices than to add them then remove later

How to change the max size of a downloaded image?

[hardy sentinel]

as in, resize it? or expanding it with more whitespace? there's Texture.Resize(..) if that's what you're after: https://docs.unity3d.com/ScriptReference/Texture2D.Resize.html

[ancient sparrow]

i mean this setting here

[hardy sentinel]

ah.. that should be in the import settings if available.. let me take a look

[ancient sparrow]

thanks

[hardy sentinel]

that should only be available in editor actually. Doable with something in this context:

class ImageImp : MonoBehaviour {
    public Sprite spr;
    public int maxSize;
    [ContextMenu("ChangeSize")]
    void ChangeSize() {
        var spritePath = AssetDatabase.GetAssetPath(spr);
        var importer = (TextureImporter) AssetImporter.GetAtPath(spritePath);
        importer.maxTextureSize = maxSize;
        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();
    }
}

probably no options to change max size of asset downloaded at runtime

but you CAN have a template texture for each max size and render a custom texture to it with a shader or Graphics.Blit

I have seen this ability but forgot. How can I add an offset to all vertices when creating a mesh?

[viral pilot]

Might require more details … otherwise I would just answer just add an offset on your vertices. Maybe you can look at procedural meshes to understand how it works

[floral flume]

PSA: Do not use BufferedRTHandleSystem in Core RP Library 13.1.
Although the documentation is there, it is merely autogenerated from their comments and there are 0 references to it in Unity's source (meaning that THEY haven't even used it themselves!)
I don't think they tested it, and its own AllocBuffer function is incapable of referencing its own m_RTHandleSystem, which breaks it.
There is also ZERO talk about it on their own site so don't get roped in by the docs.
I wasted a day implementing it.

[timber flame]

So, I have to add that offset to each vertex in a loop. I do not want it.
Suppose there is a vertex array and I would like to add an offset to each vertex without any loop over the entire vertices.
I think there is a method (a method of mesh class) to add an offset to all vertices

Also, I have removed repeated vertices and use shared vertices, it is OK but normal maps are not calculated correctly. How can I figure it out? I should use shared vertices, it reduces vertex count.
What does mesh.Optimize() do? If it removes repeated vertices itself, I can utilize it

[hollow garden]

mesh.Optimize() simply optimizes the mesh for rendering purposes

doesn't really do anything to the mesh itself

iirc

[timber flame]

The only way is to calculate normals for shared vertices manually?

[long ivy]

? Mesh.RecalculateNormals(). What are you trying to do exactly?

[quasi granite]

hey, ive been looking for a good math library for matrix math, cuz im a math guy and i like to reduce things to matrix math or regular math whenever i can cuz i can really really remember and conceptualize information and mechanics when part of it involves math
the problem is I cant find a matrix library that actually can function in unity. they all throw runtime errors everywhere and have alot of code marked as unsafe.

does anybody know of one that functions in unity?

cuz the internet has been no help to me thus far. maybe im just bad at googling

[umbral trail]

what is wrong with unity's math library?

[tribal pivot]

And whats wrong with unsafe code?

[somber swift]

There doesn’t seem to be method like that as you may see https://docs.unity3d.com/ScriptReference/Mesh.html. And even if there was, that would obviously just loop over the vertex array under the hood. And what comes to normals, you could elaborate in what way they doesn’t work correctly. In case you want to make flat shaded mesh, you can’t share vertices because you can have only one normal saved per vertex. For both flat shaded (shared vertices) and smooth shaded (individual vertices) RecalculateNormals does pretty good job.

[ancient sparrow]

why does changing the texture format of my sprite renderer turns it into blank?

[flint geyser]

Why do protected interface members can be used only in inheriting interfaces. Why not also in inheriting classes? What is its use?

[fleet lion]

can you send an example, im not entirely sure what you mean?

[flint geyser]

interface IInterface
{
  protected void a();
}
interface ICar : IInterface
{
  void b(){ a(); } //valid
}
class MyClass : IInterface
{
  void MyMethod()
  {
    a(); //invalid
  }
}```

[flint geyser]

.

[flat marsh]

that example is flawed in one way or another, MyClass doesnt implement any interface

[flint geyser]

Edited

[fleet lion]

an interface is a contract, you only specify the method, not the implementation itself. It makes no sense to want this, the interface methods are public by design

otherwise you couldnt expose your interface methods

[flat marsh]

there are defualt implementations in newer c# versions

[fleet lion]

If you want to specify specifics in an interface you should just be using an abstract class or polymorphism to extend a base class

I genuinely have no idea why you would ever want to have a default implementation of an interface like this, (as a fallback when editing things???)

[flint geyser]

For example to add some method to all derived classes

Without creating extra interface

[fleet lion]

That is the entire point of an interface, i mean the protected property

[flint geyser]

Also I code with newer C# version which permits default implementation for methods in interfaces so your note is unreliable

[fleet lion]

aah just googled it, im still not sure what your question is. A protected property by definition is only accessible to the class around it. I see no reason why it should be different here

[novel plinth]

you're confused between interface vs abstract, I think

[fleet lion]

why not just make it public if you want to expose it to the instances that implement it?

[flint geyser]

Protected property is accessible to the class and its inheritors

[flint geyser]

Not sure

My question is the reason why I can't use protected method in a derived class but can in a derived interface

[flat marsh]

not sure if c# differentiates that but maybe because IA : IB is actual inheritance and SomeClass : IA is "implements"

[flint geyser]

Any better ideas?

[fleet lion]

this seems to be a new feature that really hasn't been fully realised or thought out yet

It almost seems to me they are working on a track to merge interfaces and abstract classes

Note the part I marked red; they don't have a clear use case described here at all imo

[novel plinth]

the virtual in interface been a while added, since 8 if I'm not mistaken

very useful

[fleet lion]

Im not sure why you would want a protected member in an interface though? Just for the default implementation?

[livid kraken]

There is no point imho

[fleet lion]

i see zero use case for this

[flint geyser]

I guess the reason is that interface members are supposed to be used by external forces (classes, etc) so it would be stupid to add protected modificator to let member be used in a derived class, so it is used to prevent external forces from using the member (as with private) and also to let derived interfaces to use the member. What do you guys think about this theory?

[livid kraken]

For me it even fundamentally goes against the idea of interfaces

[flat marsh]

the use case would be to have common functionality that can be used in derived interface default implementations

[fleet lion]

the entire concept of a default implementation in an interface is flying right past me if im honoust, I would think it's not the responsibility of an interface to have a default implementation at all, so this seems kinda weird to me.

[fleet lion]

100%

i feel the same way

[flint geyser]

Read it guys

[livid kraken]

We have abstract clases that do it we dont need interfaces to take on roles from that

[flat marsh]

well you can implement a multitude of interfaces

without any inheritance chains

[livid kraken]

All a interface shoul do is guarantee me that a given class has a implementation of a given set of methods

Nothing else

[flat marsh]

why not?

[flint geyser]

It is how you use them, not all their capabilities

[fleet lion]

I feel like i would only use a specific interface if it is generic enough, if i wanted to hide certain parts of an interface to a class i would say the class should not be inheriting from the interface

since we can already use multiple interfaces i would make a second interface for the more specific scenarios, and use that for the classes that are more specific

[flat marsh]

it would be used when you have an ICar and an IPlane interface which both inherit from IVehicle.
there is probably some functionality both ICar and IPlane could use in some default implementation but noone should be able to call the base functionality directly on the class that implememnts the interface

[flint geyser]

Then what about making APIs? Hm?

[flat marsh]

so i would say protected stuff in interfaces isnt hidden from implementing classes because it doesnt relate to that class but simply because it shouldnt be used on its own

[flint geyser]

Nice vision

It has almost the same meaning as my theory

[flat marsh]

which would also explain Telovs initial question about why it works the way it does

[flint geyser]

So I think I can write this theory down for myself and use it in future

[fleet lion]

could you give an example method or property? Im still not entirely sure tbh

I think it depends a lot on a fundamental discussion about how interfaces are used if im honoust, it seems that Uri and me have a bit of a different view than you guys (which is fine of course)

[flat marsh]

sure give me a sec

just as a disclaimer i have never used that functionality, its just after googling what i think is the intended use case

[fleet lion]

im not entirely sure what you mean by this, it wouldn't influence APIs right? (as in you can still achieve the same things without that access modifier)

[flint geyser]

Rephrasing Sejadis' words: interface members marked as protected are supposed to be used not by classes but by interfaces.

Gonna give you an example wait

[flat marsh]

https://www.toptal.com/developers/hastebin/idoxewafes.csharp

[flint geyser]

Yeah, nice example

@fleet lion

You are not going to let your API's users to DoLowLevelStuff by extending ICar, right?

[flat marsh]

another disclaimer the runtime version im targeting doesnt support default implementations so there might be syntax errors

[flint geyser]

Saw somewhere that C#8.0 is supprted since unity 2020.2 or a bit later one

[flat marsh]

(not sure if AnActualCar is how you would write classes with default implementations)

[fleet lion]

This is a great example, I see what you guys are saying

With your use case I 100% understand and this makes perfect sense, a fair question for sure!

[flat marsh]

so instead of inheritance chains you can build functionality by implementing multiple interfaces

[flint geyser]

I feel like an elder explaining something in this channel

[fleet lion]

The thing is, i would choose to use an abstract class for this myself as I dont define functionality in an interface

[flat marsh]

yeah it would be useful if you want to mix and match functionality

and not create a subclass for every specific thing

[fleet lion]

I may be a bit more of a purist in that sense, I think an interface is a contract, and should not contain any functionality in any way, just specify what an inheriting class can or cannot do

[flat marsh]

like add IBoat and IBike but stuff can be a boat and a bike and maybe a plane too

[fleet lion]

yeah that is a fair point for sure

[flat marsh]

no need to create a shit ton of classes for every possible combination

just implement whatever interfaces you want

and honestly i wasnt to sure what default implementations would be used for either but this discussions was also useful for me 😄

[flint geyser]

I think your understanding is a bit limited, to contracts, but it is up to you

You can inherit from only 1 class, so making such interfaces is nice to me, I have the problem with it right now

So need interfaces

[flat marsh]

given that you work in a unity version where this is supported, can you copy paste my code for a sec and see if it is syntactically correct?

[flint geyser]

Ah, it is a big hierarchy actually

Wanna see?

[fleet lion]

that's fine. Can't agree on everything haha.

It's a frustrating issue if you want to tackle that SO thing like this for sure, best of luck. Feel free to ping me if you have a solution. I'd be interested in seeing it 🙂

[flint geyser]

Unless we work on the same project haha

[fleet lion]

Guess one of us will have to be lead 😉

[flat marsh]

nah the boss is a third person who has no idea and everything will be different 😉

[flint geyser]

The problem is not with protected modifier but with inability to inherit more than one class. Read to the end if interested.
Generally, I have interface IUsable which has methods void Use() and bool Usable(). Usable is supposed to be recursive so that you check all conditions needed to use something. So instead of returning true in every base class which inherits from IUsable I want to somehow return true by default but I think it is impossible

[flat marsh]

oh no, what i meant is copy my example into your project and see if/what errors there are. as my unity version doesnt support it i cant control if that would be correct

[flint geyser]

Do you have any solution for my problem btw?

[flat marsh]

hmm whats the problem there? any error messages? logically that should be doable with default implementaitons?

[flint geyser]

1 issue: someCar var should be of type ICar, everything else is fine (I mean works as we think)

[flint geyser]

Default implementations are a bit complicated, generally you don't inherit anything from interface, including methods with default implementation, so you can't access default implementation from a derived class itself

[flat marsh]

hmm sry, as i havent used default implementations i dont think i can really help there

[flint geyser]

Ok bye

[slender tusk]

Hi everyone, is there a way to modify scenes before building ? (But modify them just for the build, and don't change them completely?)
I would like to modify them only for the build and do not change them in the editor ^^

[tribal pivot]

https://docs.unity3d.com/ScriptReference/Build.IProcessSceneWithReport.OnProcessScene.html

Or make a copy, call them _baked scenes

[timber flame]

I did not get it. When should I use it? I create a procedural meshes, voxel based meshes

[hollow garden]

idk

never done procedural mesh stuff

[timber flame]

Yes, exactly, for voxels, games usually use flat shaders, right? so, I do not need several vertices in one point, keeping one vertex for each point is enough.

[plucky laurel]

is there a way to do ref return with "try get" pattern?

for value type

[somber swift]

afaik splitting the vertices is still the default way to do it. you could use partial derivatives to reconstruct the flat shaded normals from smooth shaded mesh but i'm not sure how performant that is. usually for low poly meshes, the vertice count is so low anyways few vertices here and there doesn't make much difference

[sage radish]

Not really. I use this pattern, but I don't particularly like it:

public ref T TryGet<T>(out bool isValid);

ref var matrix = TryGet<Matrix4x4>(out var isValid);
if (isValid) { ... }

Annoying thing with this pattern is you will always need to return something, so when it's not valid, I return some private static field.

[plucky laurel]

yeah figured

was worth a try anyway

[proud field]

hey, i saw that you can run a script at the startup, you can add something on the player loop, but, is that possible but is it possible to do something after "start" (and also awake)

[plucky laurel]

you can look at for reference https://github.com/Cysharp/UniTask/blob/03097f08e2d66520f2513a1e245b1904f4ba87a4/src/UniTask/Assets/Plugins/UniTask/Runtime/PlayerLoopHelper.cs

i havent seen the actual playerloop dump in a long time so cant say if awake/start are separated but you certainly can inject your init before first update, which will be after start

[proud field]

hmm

but none of the things in playerloop are done once

[plucky laurel]

yes approach it as ECS

[proud field]

as what ?

[plucky laurel]

just flag your object as "processed"

[proud field]

ah yes, a bit brutal but yes

sad that we can't edit the scene initialisation thing

[plucky laurel]

or remove it from initialization list

or whatever there are many approaches to this

[proud field]

yep ahah, i'm just falling deeply in unity and the doc is not everytime clear as i expect 😂

[maiden turtle]

Hi. I need to get the bytes associated with a SerializedProperty, it can be of any unmanaged value type

// This one I have created myself, it keeps the new value.
SerializedProperty localProp;

// This one I have got as a parameter in my property drawer,
// it has a _bytes fixed size byte array.
SerializedProperty byteBufferProp;

// I just want to copy the value of localProp into byteBufferProp.
// localProp.CopyTo(byteBufferProp);

// My only idea is like this currently:
object localPropValue = typeof(LocalPropWrapperType)
    .GetField(selectedPropName)
    .GetValue(localPropAsObject);

var bytesProp = elementProperty.FindPropertyRelative("_bytes");
int length = bytesProp.fixedBufferSize;

// Reuse a single buffer to generate less garbage.
_cannotUseStackallocWorkaroundBuffer ??= new byte[length];

// Binary serialize the object into this buffer.
// ?? How to keep this behavior in sync with SerializedProperty?
// What about the struct alignment? Does everything have to be custom??
// I'd like to reuse their system, manual things like this feel more like a burden.
// localPropValue.WriteBytes(_cannotUseStackallocWorkaroundBuffer);

for (int j = 0; j < length; j++)
    byteBufferProp.GetArrayElementAtIndex(j).intValue = _cannotUseStackallocWorkaroundBuffer[j];

// Maybe like is there some function that does the following:
// That would be perfect for my usecase (as long as there is a way to cast it back).
BlockCopy(localProp.bytePointer[0 .. localProp.byteLength], _cannotUseStackallocWorkaroundBuffer);

My code so far

https://github.com/AntonC9018/PropertyDrawerBytesTest/blob/7b32025c35f1c7fe599220f198f3e84fb8498547/Assets/Source/BytesVersatilePropertyDrawer.cs

[maiden turtle]

Has anyone tried making unity think a byte buffer is of some particular type?

It feels to me that is impossible

(in context of a serialized property)

is there a way to get the move direction to be 0 or 1 and nothing in between?

atm i'm getting my move direction by

rigidbody.velocity.normalized

is there a way to only allow 0's and 1's?
so I know clearly where it's moving

[tribal pivot]

Do you know what normalized is?

[unique ermine]

not really tbh

[tribal pivot]

https://docs.unity3d.com/ScriptReference/Vector3-normalized.html

It makes it 1.

So you are asking, im doing this which makes it 1, how can i make it 0?

What you want is, check if 'rigidbody.velocity.magnitude > 0'

If there is some velocity. Probably you want > 0.1 for some wiggle room

(note this is code-advanced, normalizing vectors is a bit more basic)

[unique ermine]

eyyy >:(( but true from a mathical perspectiv I guess

I want to draw the predicted path of a Rigidbody2D object, is there some way to get the position of it x frames in the future?

[unkempt nova]

In general or for trajectory prediction?

In general, I think you can simulate it. Sounds like pain, never done it. This looks like the way I've heard it can be done: https://austin-mackrell.medium.com/unity-trajectory-prediction-simulation-method-5b441ee1604
For trajectory, there are many tutorials on doing it in Unity. Just google "Unity trajectory prediction"

[soft hollow]

Hey, would really appreciate the help here:
Any idea on why the camera drifts upwards or towards the left or right depending on where you're moving?
https://codeshare.io/4em9qj
Willing to pay for this

[raw lily]

Hey! What's an optimal way to sort a list by property in csharp/unity?

[humble onyx]

LINQ is one nice way to do it

[granite viper]

@soft hollow can you post a video of it happening?

is your camera parented to anything else

and this is the only place your camera is referenced?

[soft hollow]

Sure thing, give me a second

[soft hollow]

Yes, the camera is inside the head bone

[soft hollow]

Yes

@granite viper

[granite viper]

@soft hollow you're rotating your camera using a LookAt -- I don't know how m_headTarget is set, but I'm guessing it's probably a word position

so as you move your body the camera is continuing to LookAt m_headTarget

oh nevermind, it's a Transform

so yah, if headTarget is a transform in the world it'll just keep looking at it

you're also moving the camera before updating the headTarget position

[soft hollow]

What can I do to fix the drifting then? @granite viper

[granite viper]

don't do what you're doing lol

try moving the LookAt after you update the headTarget position

but that's not how I'd do a first person camera

[soft hollow]

Yes, sorry, I mean what are my options for fixing it

[granite viper]

I'd just set the camera rotation directly

[soft hollow]

What would happen with the IK then?

[granite viper]

I haven't worked with IK before -- is that why you have a headTarget transform?

for the IK?

[soft hollow]

Yes

[granite viper]

if headTarget is used for IK, then you should set the camera rotation and then set the headTarget from the rotation

rather than the other way around

[soft hollow]

That would still make the headtarget drift wouldn't it?

[granite viper]

no?

the issue you're having isn't drift

it's the fact that the camera is looking at a fixed point in space

[soft hollow]

It's not tho

It's looking at the headtarget

Which is drifting

[granite viper]

yeah -- the headtarget is a fixed point in space

[soft hollow]

Gotcha

[granite viper]

I mean I could be interpreting your code somewhat incorrectly but I think my point still stands

having two things relying on each other for state is a bad idea

have your dependency hierarchy be camera -> headTarget -> head IK

rather than camera <-> headTarget -> head IK

[soft hollow]

Yeah, you're right

Could you help me fix it?

[granite viper]

first try moving the LookAt under the headTarget update function

[soft hollow]

++

[soft hollow]

Now it just spins around like crazy lol

[golden saddle]

question about dealing with generic types. I've got a class Conditional<T> where T is whatever value type of I pass into it that return a bool. I have a single list of these of various Conditional types (via a common interface, IConditional); I also have a list of another interface, ICriteria, which can be of any implementing type. What I want to do is take the list of ICriteria for loop through it, submitting each one to any IConditional of the matching type. The attached code breaks because "Conditional<criterion.GetType()>" doesn't seem to evaluate properly.

[tribal pivot]

Conditional<criterion.GetType()>
This is indeed not possible, because generics are checked at compile time. They are constant, this is a variable.

What you pass in there cannot change

The only way you can do this if you add the T in Value.

Value<T>(List<ICriteria> criteria)
You'll notice that then you could also pass in a Value<T>(List<Conditional<T> crit)

https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/generics/generics-in-the-run-time

[granite viper]

you need a non-generic base interface for Conditional that has a method or property that returns a Type

then implement that interface and property in your generic class and return typeof( T )

oh you already have an interface

so add it to IConditional

then you can do something like

foreach( IConditional condition in conditionals ) {
  if( condition.type == criterion.GetType() ) {
    // do your thing
  }
}

[tribal pivot]

Whats the thing then? You cant easily cast the IConditional to a Conditional<T> in that case.

[granite viper]

you're not casting it to anything

you're just dealing with the interface

[tribal pivot]

Thats what he's trying to do, and thats impossible. You'd modify your interface to accept an object parameter?

[granite viper]

you'd make a non-generic overload that takes the interface and cast it in the generic

I misunderstood your initial question, you are correct

he's already doing that since he's passing in ICriterion into Test in his snippet rather than the actual type

not the most efficient for hot code to have the boxing/unboxing but w/e

[tribal pivot]

Hence, if its possible, make the Value<T>

[granite viper]

yes that would be ideal

[golden saddle]

running into the casting issue now. Not sure I follow w/r/t Value<T>

[tribal pivot]

This

[golden saddle]

thanks. Gimme a minute to try to decipher it 😛

[granite viper]

for ex.

public int Value<T>( List<T> criteria) where T : ICreteria {
  // etc.
  foreach( T criterion in criteria ) {
    foreach( var condition in conditionals ) {
      if( condition.GetType() == typeof(Conditional<T>) ) {
        pass &= condition.Test( criterion );
      }
    }
  } 
}

if you don't know what value T should be at your calling site then you're out of luck

and you'll need to do my version

[tribal pivot]

There's a newer syntax which is kinda nice

if(condition is Conditional<T> conditionalT)

makes a new variable immediately for it

[granite viper]

yeah good tip, I missed the cast in my snippet

[golden saddle]

I feel like it would almost be saner to just test for the specific Types that might otherwise implement ICriteria

[knotty sable]

Is there a way to scope VS to include the packages folder in unity so I can get better syntax highlighting/error checking?

[granite viper]

I think it should already do that

[proud field]

            {

                {
                    loop.subSystemList[i].updateDelegate += LoadScene;
                    break;
                }
            } 
            PlayerLoop.SetPlayerLoop(loop);```

hey i noticed that i can make script-changes in runtime without restarting the scene, which i usually cant do without errors because of object pooling or something. if im debugging externally and the debugger is set to pause and i edited the script, the debugger continues when i hit play, but the compiling of the script edits/changes happen after i stop the debugger and return to unity right?

Any one knows the difference between GL.IssuePluginEvent and CommandBuffer.IssuePluginEvent ?

Under my testing, both of them can trigger native rendering event, but it seems the native event are triggered in different time. I could not find any documentation describe the difference...

// Option 1:
                GL.IssuePluginEvent(getRenderEventFunc(), 0);

                // Option 2
                CommandBuffer cmd = new CommandBuffer();
                cmd.IssuePluginEvent(getRenderEventFunc(), 0);
                UnityEngine.Graphics.ExecuteCommandBuffer(cmd);

It's supposed that Option 1 is equals to Option 2, but actually is not. I want to figure out why...

[tribal pivot]

Commandbuffers usually are scheduled to the camera using cam.AddCommandBuffer

[timber flame]

what is the benefit of IJobParallelFor with respect to standard Parallel.For?

[sly grove]

IJobParallelFor is how you define a parallel job in UNity's job system

Parallel.For is a C# thing

that has nothing to do with Unity

[timber flame]

I know. I mean both have similar approaches to execute independent procedures parallel

I have multi dim array with some calculation. Which one do you choose to handle it?

[sage radish]

Jobs can be scheduled with other jobs as dependencies that are resolved efficiently. Also, jobs can be compiled with Burst.

[sly grove]

IJobParallelFor uses Unity's job system. Parallel.For uses some internal C# thread pool. It won't take advantage of Unity's burst compilation or integrate with Unity's job system at all

[timber flame]

with Burst, OK thanks

I would like to use it minimally without Burst. As I mentioned, there is a multi dim array, inside it, calculate some addition, multiplication, there are some if/conditions and finally store them in an array/list.
Is it suitable to use IJobParallelFor for this scenario?

Parallel.For(0,length,(i)=>{
   //...
})

[drifting galleon]

yeah that is likely burstable

[timber flame]

Let me say, I have tested Parallel.For, it is disappointing in my scenario. I mean the execution time is worse
Array size 32*32*32
Parallel length 32
Maybe because the size is small.
Even with Partitioner

[mighty cipher]

Hi ! I'm having a little problem, with some math on the calculation of a specific angle and would need some help on that if anyone around is Good with this.

Here is some code

private Vector2 mousePosition;
        private Vector2 fromVector2M = new Vector2(0.5f, 1f);
        private Vector2 centercircle = new Vector2(0.5f, 0.5f);
        private Vector2 toVector2M;


And then in Update run this part :

            mousePosition = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
            toVector2M = new Vector2(mousePosition.x / Screen.width, mousePosition.y / Screen.height);
            float angle =
                (Mathf.Atan2(fromVector2M.y - centercircle.y, fromVector2M.x - centercircle.x) -
                 Mathf.Atan2(toVector2M.y - centercircle.y, toVector2M.x - centercircle.x)) * Mathf.Rad2Deg;
            if (angle < 0)
            {
                angle += 360;
            }

            CurentMenuItem = (int) Mathf.RoundToInt(angle / (360f / menuItems));

The issue is, it's not targetting well on X elements

[sage radish]

Why would you want to avoid using Burst? It's literally just adding a [BurstCompile] attribute on the job struct.

[timber flame]

OK, I test it, hopefully get better result.
I would like to know if it is useful for small 3d array size.
32 length array of (32*32)

[drifting galleon]

it's useful for any array size

[sage radish]

That depends on how much work you're doing for each element. There is some small overhead with both scheduling jobs and using Parallel.For.

[timber flame]

Also, there are 3*3*3 chunks for example. I run them using Task.Run for each.
Maybe, I should get rid of it too and use Job for it as well.
My game is voxel based.
Each chunk has size 32*32*32

[drifting galleon]

true, but you can easily just manually 'batch' it

[sage radish]

For Jobs especially, you may need to convert the data to a NativeArray if it isn't already prepared that way.

But you'll definitely get better performance with Jobs and Burst than manual threading or Parallel.For.

Assuming you adapt your data structures to it

[timber flame]

So, it is weird why my code with Parallel.For was worse or at least the same result

[tough tulip]

before going with Jobs or Parallel, you need to decide first on what youre going to do. both do the job, but which is efficient can be done by only testing it.
Jobs might be faster to process, but might also be slow on allocation. because it depends on where you get your array from. if youre using Parallel, you have the freedom to continue using the managed array which is already allocated. so just profile them both if your code has a tight budget

[timber flame]

@sage radish So worth to test, thanks.
@drifting galleon thanks
@tough tulip thanks
@sly grove thanks

[drifting galleon]

you don't necessarily have to reallocate anything for jobs. often you can just take the managed array and reinterpret the memory

[tough tulip]

depends on the use case yes.
NativeArray constructor takes a managed array. allocates native buffer, and copies the managed array to native array

[timber flame]

Main problem.
Generate mesh for voxels 🙂

[drifting galleon]

easily doable with jobs

[undone coral]

is this for big macroscopic voxels minecraft style?

have you been implementing something from the literature? i forget, you've been asking about this for a while right

[undone coral]

what is your objective?

[undone coral]

it really depends what's in the //... part

[undone coral]

take a look at UniTask, it has a way to do this

[undone coral]

ExecuteCommandBuffer is synchronous with camera rendering and supports batching

[undone coral]

huh?

[undone coral]

don't use Conditional<T>, use

interface ICondition {
  bool Evaluate(IContext context);
}

class ComparisonCondition : ICondition {
  ArithmeticOperator operator;
  IValue leftOperand;
  IValue rightOperand;
  bool Evaluate(IContext context) {
    var left = leftOperand?.GetFloatValue(context) ?? context.leftOperand.GetFloatValue(context);
    var right = rightOperand?.GetFloatValue(context) ?? context.rightOperand.GetFloatValue(context);
    switch (operator) {
      case ArithmeticOperator.GreaterThan:
        return left > right;
      ...
    }
  }
}

does this make sense?

context can be "current value" instead of left and right operand

don't use generics

class ComparisonCondition : ICondition {
  ArithmeticOperator operator;
  IValue leftOperand;
  IValue rightOperand;
  bool Evaluate(IContext context) {
    var left = leftOperand?.GetFloatValue(context)
     ?? context.currentValue.GetFloatValue(context);
    var right = rightOperand?.GetFloatValue(context)
     ?? context.currentValue.GetFloatValue(context);
    switch (operator) {
      case ArithmeticOperator.GreaterThan:
        return left > right;
      ...
    }
  }
}

another way of thinking about it

do not write a signature into Evaluate

add fields to a "context" that can be interpreted however you need by conditions

or whatever little meta-programming thing you're trying to do

if i were you i would avoid metaprogramming at all and directly script

[golden saddle]

So - the background here is that I want to award the player "Action Points" that can be used in specific circumstance: IE, 1 Action Point to use in North America only; or 1 Action Point to use on a Diplomatic Action; or 1 Point to use on a Territory where the opponent has at least 1 point. I want to do this generally rather than code up each card. So the question is, how can I submit the context of some spending of those action points to evaluate if this point is eligible for that purpose.

[undone coral]

var greaterThanFive = new ComparisonCondition() {
   rightOperand = new ConstValue(5),
   operator = ArithemticOperator.GreaterThan
};

...

[undone coral]

i get what you are going for and you're modeling it poorly 😦

[golden saddle]

OK. I don't think I have an intuitive high-level understanding of the initial code you posted, could you kind of describe what's going on there?

[soft hollow]

Hey @granite viper

[undone coral]

you can use

class CustomIsPlayable : ICondition {
 bool Evaluate(IContext context) {
  var currentAction = context.currentAction;
  if (currentAction == null) {
   return false;
  }
  return currentAction.target.region == Regions.NORTH_AMERICA
     || currentAction.type == ActionTypes.DIPLOMATIC
     || context.GetScoreFor(Players.OPPONENT, currentAction.target.territory) >= 1;
 }
}

[glacial geode]

im asking what would be the best way to get started with converting a sequenced code into a parallel one

but i am having some trouble to see if there is a better way to do so

like per example, atm i used ValueTask to try and leave the main thread free

[golden saddle]

OK. What this seems to be getting at is that instead of submitting Type <T> into the Evaluate() function as I did with test, but to instead pass in an IContext; this gets away from the generic typing altogether.

[undone coral]

part 2:

bool CanPlay(IContext context, Action action) {
 var toEval = context.Clone();
 toEval.currentAction = action;
 return toEval.GetAllApplicableConditions(action)
    .All(condition => condition.Evaluate(toEval))
    && action.cost > context.currentActionPoints;
}

[undone coral]

you don't need generics because you don't need to express any comparisons except between floats

a float is a superset of everything you would want to compare

so no point in making it generic

part 2 could be made simpler if you put the code where you need it to be so to speak

it's easier to enumerate through lists of enums in the right places

than to have a general crappy-version-of-LISP thing going on

does that make sense?

[golden saddle]

Uhh I wish I could say it did. Not sure how a list of enums enters into play here?

[undone coral]

suppose this card was titled "The Imperialist: Gain a free action in North America; or a free diplomatic action; or in any territory where your opponent has at least 1 point"

bool CanPlay(IContext context, Action currentAction) {
 EnchantmentEnum[] enchantments = context.GetAllActionEnchantments();
 // check cost, do a bunch of stuff
 return enchantments.All(e => {
  switch (e) {
   case EnchantmentEnum.THE_IMPERIALIST:
    return !context.GetPlayerHasEnchantment(Players.FRIENDLY, EnchantmentEnum.SPENT_THE_IMPERALIST) && 
     (currentAction.target.region == Regions.NORTH_AMERICA
     || currentAction.type == ActionTypes.DIPLOMATIC
     || context.GetScoreFor(Players.OPPONENT, currentAction.target.territory)) >= 1
   ...
  }
 });
}

then the code for The Imperialist would be

var theImperalist = new Card() {
 title = "The Imperalist",
 description = "At the start of every turn, gain a free action in North America; or a free diplomatic action; or in any territory where your opponent has at least 1 point",
 cost = 1,
 friendlyActionEnchantments = new [] {EnchantmentEnum.THE_IMPERALIST}
};

which can be encoded directly in a scriptable object

so when something is complicated, don't make a metaprogramming thing. just declare an enum, and check for it in the right places @golden saddle

in this implementation The Imperialist would need to put another enchantment into play indicating it was spent this turn

alternatively you can create an enchantment token tracker if this is a common thing you do in your game

[golden saddle]

I think I can un-genericize the code and move on from that approach, but shifting everything into scriptable objects with enums is probably too big of an overhaul for the scope of the project right now.

[undone coral]

it can be whatever you need it to be

not a scriptable object

but more like, don't inject code

coordinate around an enum

that corresponds to the effect

this thing that you are doing, this particular card, it's really hard to do

there's a lot that would go into its implementation and you are not going to make something bug free via meta programming

it's a really complicated card lol

[golden saddle]

I'm doing implementations of the board games Twilight Struggle and Imperial Struggle, just FYI. Picking them because they are hard 😛

[undone coral]

you are F'd

hopefully not for the board game's creators right?

[golden saddle]

hobby projects. but hopefully one day soon.

[undone coral]

is this the first time you've tried to make this kind of game?

[golden saddle]

sort of. Each time I start I run into some basic architecture problem, then I restart using the lessons from the last attempt. So this is maybe evolution #5.

[undone coral]

lol

good good

you are on a good journey

have you looked at the source to XMage?

[golden saddle]

Finger's X'd. Those games have a reputation for being "difficult" so I figured if I can figure those out, I can figure out any type of turn-based game.

I have not seen or heard of Xmage

[undone coral]

okay

https://github.com/magefree/mage/blob/master/Mage.Sets/src/mage/cards/u/UktabiKong.java @golden saddle here's an example

this is really complicated

Need some help with importing a native unity plugin

I get this error

the .dll is only targeting the editor

also, I have to use unity 5.6.3 unfortunatly

thank you!

[drifting galleon]

you forgot to add .dll to the dllimport,
why do you HAVE to use 5.6.3???

[placid violet]

Making a mod for a game

Game in unity 5.6.3

[drifting galleon]

oof

[placid violet]

Adding the .dll produces the same results unfortunately

[placid violet]

It’s worse than “oof”

[drifting galleon]

....not modding the game is always an option XD

[placid violet]

“Just don’t do it”

Bruh

[drifting galleon]

XD

[drifting galleon]

oh, uhm, you have not added the absolute path to your file

you have to specify the search directory

[placid violet]

I do?

Damn

[placid violet]

tried that

        private const string DownloadFileLibrary = "Assets/Plugins/Native/Utilities/libdownloadfile.dll";
        
        [DllImport(DownloadFileLibrary, EntryPoint = "download_file")]

didnt work

[drifting galleon]

you need to specify an ABSOLUTE path

[placid violet]

oh wow

ok

is there like a variable I can use?

because i plan to redistributew

[drifting galleon]

Application.dataPath might be the correct one, but i'm not entirely certain. would have to look it up to be certain

[placid violet]

aaaa

[drifting galleon]

there's also this if you have a lot of DllImports: https://docs.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.defaultdllimportsearchpathsattribute?view=net-6.0

[placid violet]

cant use it cause it aint const 😦

MSDN is always based

i think this is impossible then

I moved the dll to a path which is relitive to the script

would that work?

[stray plinth]

Hey, did anyone ever work with GoogleSheetsAPI on Android?

[placid violet]

is this Unity's fault?

[undone coral]

you're going to spend a lot of time wheedling on authorization to do that

[undone coral]

it's telling you what the error is

[placid violet]

but the dll is right there

[undone coral]

the paths are not the same

maybe start with a unity tutorial

[placid violet]

bruh

[placid violet]

they are tho

i literally copied and pasted

[undone coral]

have you tried closing and reopening the editor?

[placid violet]

yes

[undone coral]

then the architectures are wrong

you'll have to rebuild the .dll

[placid violet]

it isnt though

i have

its building for w64 mingw

[undone coral]

okay well

i think you'll figure it out

[placid violet]

?

[placid violet]

I can't figure it out, thats why im asking lol

[stray plinth]

Yeah thats my issue just getting through the credential process with GoogleCertificate.

[placid violet]

removing the .dll and the path gives me 2 new errrs

[stray plinth]

The problem is that I cant find any working examples of reading the credentials.json on Android, no matter its location

[undone coral]

why do you need to access a google sheet from a game?

[wispy epoch]

I'm using Playfab to store the upgrade levels for each gun in my arsenal to a player's cloud account. The player can select 2 weapons, a primary and secondary to take into a battle. When they enter the battle i need to know how much damage the weapons should do and how much fire rate, etc, based on the upgraded amount for each stat of both guns.

What is the most efficient way to do this. Obviously im not going to make an api call every time the player switches weapons to grab the levels for each stat of the selected gun, but what is better than that. All i can think of is setting 8 variables on awake in my game manager script that correlate to the 4 stats of each weapon, and then every time i switch guns i have to have a flag that says whether the player is switching to primary or secondary gun and set the new stats based on that. But this seems super inefficient as far as clean code.

Is there a way to make like 3 objects or something with 4 stats that return the damage, fire rate, reload speed, and mag size and i can set 2 objects to be primary stats and secondary stats, and just switch either object in for the 3rd object that would be current gun stats? I think this would be cleaner but not sure how to implement that. I was told its a bad idea to store data in a scriptable objects but that might have just been for long term data storage

Okay so if its okay to manipulate data in a scriptable object, what if i simply add 4 variables to my scriptable object for each gun which hold the 4 stats to use and dont touch them outside of the Game Scene, but on start of a new game, i set the 4 variables equal to the base stats plus whatever level the stat has been upgraded to? Would that work or is this bad practice and i shouldnt be manipulating scriptable objects on start of every new game

[placid violet]

yeah that would work fine

if its just readonly

it wouldnt be too slow

[wispy epoch]

Awesome I'll try that out. If im just setting them via code and not in the editor, should i make them private variables?

[placid violet]

absolutley

alwyas prefer private over publicx

its one of the principles of OOP

[wispy epoch]

been a while since i took a class in college on OOP. oops

[placid violet]

OOPs

[placid violet]

figured out the issue

my libnrary was linking with libcurl

but i was dynamically linking

not static

[undone coral]

create a single object that describes the entire User data that should be stored / fetched from the server

retrieve it when your user has logged in. keep it updated whenever your client changes it

@wispy epoch use UniRx to make this easier on yourself

ReactiveProperty<User> m_User = new ReactiveProperty<User>();
IReadOnlyReactiveProperty<User> user { get; }
void SetUser(User user) { m_User.SetValueAndForceNotify(user); }


// whenever you need to keep the UI updated
user.SelectMany(u => u.weapons)
    .Subscribe(weapons => {
      // update the weapons UI here
    })
    .AddTo(this);

// whenever you need to change something
var userDoc = user.Value;
userDoc.weapons[2].level = 3;
SetUser(userDoc);

// to set up saving automatically to play fab whenever you modify data
user.Subscribe(async u => {
   await playFabApi.SaveDocument( u /** or whatever .... **/);
  })
  .AddTo(this);

// get the initial data
var userDoc = await playFabApi.GetUserDocumentOrWhateverTheApiIs();
m_User.SetValueAndForceNotify(userDoc);

does this make sense?

no scriptable objects

they don't make sense

just have one object represent the entire thing you need

if you need to scriptable object that garbage do

class MyScriptableObject : ScriptableObject {
  public User user;
}

and declare User [Serializable]

[wispy epoch]

this is what my playfab data currently looks like and im just grabbing the levels when the player opens the inspect window for that gun, and changing the levels for that gun if the user completes an upgrade purchase. You're saying i should have all the data present in the playfab data but isnt this inefficient because the base damage and damage increment and icon and so on all are specific to each gun but unchanging

[undone coral]

it'll be way too clunky to do this

your player data should just be 1 key and the value should be the entire user document

[wispy epoch]

that seems more clunky and hard to read to me than what im currently doing

[undone coral]

you're already experiencing the clunk

there's no value in optimizing 50 bytes versus 5,000 or whatever

it will never matter

if that stuff mattered to you you wouldn't use JSON

you are getting a huge amount of clunk from having all these keys

and then you will eventually have a different type in there

and you'll have to keep track of the type

it's meaningless

this is coming from someone who's written multiplayer games

the pattern i showed is bulletproof - you'll always have the latest values locally and saved on the server in all but the buggiest cases

you already made a big mistake by using scriptable objects as something you also change in the game

if i understood correctly

you need 1 object (or a collection of them) representing your game state when you make networked games

[wispy epoch]

well no i havent been manipulating the data in my scriptable objects up until this point. Thats my question is im trying to figure out the easiest way to get the levels from playfab when you start up a game, for the 2 guns equipped, and it all seems very clunky bo matter what method i go with

[undone coral]

so it goes. model your game as 1 object (or a collection of identically typed objects)

[wispy epoch]

the data in my scriptable objects is constant but there's s a lot of it for each weapon. about 12 variables

[wispy epoch]

Hey ive seen this problem before and not sure what i did to fix it, i think switching to URP, but when the player moves quickly and enemies are following also going at decent rate of speed, when the camera is following the player, the enemies become blurry. The blur goes away when the player stops moving.

Now this is the same game i had the original problem with but URP made it go away in the editor as well as on my 4 test devices, (3 models of iphones and 1 android). I thought the problem was fixed but now im getting reports from one of my beta testers that the issue is happening for them as well. This is 1 user out of 20 and they are using a 22. Why could this be? I asked if this was an issue broadly for the model of phone they are using (brand new) and they said this is the only game they see it happening for but maybe other games aren't using the same visuals where enemies chase after the player? I doubt it but it seems like a rendering issue in game, just dont know why it would only be happening for this user.

For extra context this user is the only android user ive sent the build too. Ive tested it personally on my android test device but this is the only tester its gone out to on the platform

[stray plinth]

We are doing levelTesting and we want to stream data from it at runtime with this for further adjustments.

[flint sage]

Can't you just put it in resources?

Also, why not use the oauth api instead and let the user sign in with their own id that has access to the file

ServiceAccount auth isn't really for apps, it's for headless services that run on e.g. your build machine

[stray plinth]

I've tried putting it in resources, but a new error arises where the constructor for the GoogleCertificate is not found. We don't want to use OAUTH api, since we are developing mobile and we don't want testers to deal with that.

[flint sage]

That sounds like you didn't include all dependencies

[stray plinth]

https://answers.unity.com/questions/1778812/googleapiexception-parameter-spreadsheetid-is-miss.html
This was the error iirc, I didn't want to go as far as link.xml since then I need a seperate system to strip it from release builds, etc.
I was actually hoping that this would work out of the box. Supposedly this person: https://github.com/UnityAdventureES/GoogleSheets-For-Unity/blob/main/GoogleSheetsForUnity.cs made it work

[flint sage]

Idk, sounds like they would still need a link.xml or something basd on that repo

[stray plinth]

To be honest I could just do it via GET/POST requests, but I really wanted to use the api for this. Makes it a whole lot less clunky...

How could DateTime.Now.ToLocalTime().ToString() become 4/3/2022 8:31:39 a. m. ? I've never seen a space in-between a. and m. like this before and I can't parse the the string back into a DateTime correctly because of this

DateTime.Now.ToLocalTime().ToString("dddd, dd MMMM yyyy")

Did you try with any of these https://www.c-sharpcorner.com/blogs/date-and-time-format-in-c-sharp-programming1?

Yeah, in retrospect, I should've specified the format >< Thanks

Hello,
I am setting up a CI/CD pipeline with TeamCity for a unity project to automating build.
When I make a build, it fails with an error that UnityShaderCompiler could not connect ipc like below.

"Shader compiler initialization error: Failed to get ipc connection from UnityShaderCompiler.exe shader compiler! C:/Program Files/Unity/Hub/Editor/2021.1.7f1/Editor/Data/Tools/UnityShaderCompiler.exe"

could somebody please tell, what can be a solution for this ?

[sage radish]

Could be a firewall problem. Have you see any administrator popup appear on the build server?

[sage radish]

Actually, it seems this error occurs when the build agent is run as a service.

Hi guys! Anyone knows how to run pod install in a c# script?

[forest nymph]

maybe this is more of a question for here: #archived-code-general message

[flint sage]

Just destroy your player and recreate it based on the latest save data?

[forest nymph]

ah interesting idea, I don't use any saves (apart from a leaderboard) but I could reinstantiate a prefab

thanks

Thank you @sage radish . I increased the windows desktop heap size limit for the pc. and after restart it was able to make a successful build. For now this seems to be working well.
I will keep this link saved for future in case it happens again.

Anyone used to work with Wwise ?

On a project, i can't get the sounds to play with Wwise on Unity, note that the integration has been made by a sound designer, so it should be fine.... but sadly when i play the event it's saying that the sound doesn't exist, and that i should check my settings, thing i have done already 10 times but still no clue about how to make it work on my end without downloading Wwise

[wooden cedar]

I'd probably just open it in Wwise, if unity says the sound doesn't exist, it's the only way to be sure

Either an implementation step was missed, the Wwise export was broken, or the integration between the two is broken
