I did not know this!

For some reason, raycasts have been intimidating to me so I've sort of been avoiding them

[sour fulcrum]

raycasts are super simple and will be a very common tool in your toolkit

[wicked stratus]

All roads seem to be leading to them, so I think it's time to get over my hesitation 😅

[woeful coyote]

See video below
My camera is 'snapping' when I try to move it. Previously, when I referenced the camera, I used camera for the variable name. I changed it to cam due to console warnings, but now I get this issue. I have ruled out multi-script conflict. What is happening? I'm new to this.

Here's the script, it's kind of short

public Camera cam;
    private float xRotation = 0f;

    public float xSensitivity = 30f;
    public float ySensitivity = 30f;

    public void processLook(Vector2 input)
    {
        float mouseX = input.x;
        float mouseY = input.y;

        // Calculate UP and DOWN
        xRotation -= (mouseY * Time.deltaTime) * ySensitivity;
        xRotation = Mathf.Clamp(xRotation, -80f, 80f);

        // Apply to camera transform
        cam.transform.localRotation = Quaternion.Euler(xRotation, 0, 0);

        // Transform for LEFT and RIGHT
        transform.Rotate(Vector3.up * (mouseX * Time.deltaTime) * xSensitivity);
    }

I just realized it may not be noticeable, but the camera does not move smoothly, it snaps to places when looking around

[woeful coyote]

processLook() is called from another manager script:

private void LateUpdate()
    {
        look.processLook(onFoot.Look.ReadValue<Vector2>());
    }

Sorry for the code wall

[narrow idol]

hello which channel can i ask for general help in?

[woeful coyote]

#💻┃unity-talk for non-programming I think

[woeful coyote]

Best to use the given channels instead

[narrow idol]

oh okay, my problem is with installing unity so ill ask there.

[naive pawn]

assuming that look input is from mouse delta, don't use deltaTime for it

mouse delta is already a delta, already per frame

[woeful coyote]

So I just remove both instances of DeltaTime?

[naive pawn]

yeah

you'll have to reduce the sensitivity to compensate

not sure it's the issue here, but definitely an issue

[woeful coyote]

Works as expected, thanks!
Strangely the tutorial I was following used delta and it worked, but the look works for me now

Thanks again

[naive pawn]

yeah tutorials aren't always guaranteed to prescribe best practices

[prisma shard]

Sometimes I dump my entire game code into an AI to scan for any bugs I might have made. Am I wrong to be paranoid of doing this with Chinese models? Like I want to see how good they are at debugging in comparison to stuff like OpenAI and Claude but i have no idea what they might do with the code because they likely are much less afraid of being sued

[naive pawn]

paranoid for what?

[prisma shard]

Of them eventually stealing it and making a duplicate game if it got advanced far enough

[naive pawn]

i don't think business practices are much different for any of the genAI as a service companies

[naive pawn]

they're definitely not going to do that lmao

[sour fulcrum]

I don't think paranoia about a specific country potentially doing something with data your providing them is suitable for this server tbh

[naive pawn]

they aren't sifting through all the input for the 0.001% that happens to be game code

[prisma shard]

Idk I just know how good even an dated agency like the FBI is at keyword searching through the internet. Maybe they have a way to find coherent holistic codes from doing the same

[naive pawn]

they do

they just aren't

because that's not economically viable

if they want to make money doing shady things, there are more lucrative ways to use the data

[prisma shard]

Obviously no indie game would be cyberpunk but if someone dumped the entire code of cyberpunk 2077 into Qwen 6 months before the game released, u dont think there is any danger of doing that?

[naive pawn]

no

well there is danger of you getting sued because you broke NDA, probably

i don't know what qwen is, but assuming they're a typical chatbot company with a ton of traffic, they aren't sifting through the traffic for code to steal

especially given that a) they wouldn't know it's there to begin with, b) it wouldn't be contiguous, c) they wouldn't have the assets and infrastructure to build and publish the game anyways, d) they don't have the marketing to make it an attractive financial choice

[prisma shard]

Maybe im thinking of stealing code wrong when i heard it used. Because i always hear people saying google and openai is making money off of stolen code and im not entirely sure what that means

[naive pawn]

they aren't just republishing the code as-is

[sour fulcrum]

Imagine if one of your users dumped your games source code into Qwen 6 😛

[naive pawn]

machine learning training gets better when you give it more inputs and more time. the argument in that regard is that the genAI companies are effectively pirating to get more inputs/training data, and then benefitting economically from the higher-quality model

[brisk robin]

(Sorry, don't mean to interrupt the conversation, just want to get this question out.) When "leaningin" is false, I want the game to change the parent of "opptextbox" to be the new canvas and resize it. My understanding of my If statements here is that, if the parent ISN'T oppcanvas, then frame 1, the update function should run the stuff I commented "frame 1," then on the next update frame, it should run the "frame 2" section. Am I understanding the update function properly?

[prisma shard]

If you are implying someone is going to decompile it, i will assure that doesnt happen xd

[naive pawn]

you can't

the only 100% assurance is not publishing it to begin with

[prisma shard]

Ill be honest i really only ever hear of godot code being decompiled.

[sour fulcrum]

most unity codes are decompilable

anything compiled with mono

[sour fulcrum]

I have witnessed first hand multiple newbie modders for unity games dump a compiled game right into an ai assistant not knowing thats not ok

[naive pawn]

to publish the game, you need to publish the instructions for how the game works. the instructions can be extracted, and then reversed into what they couldve been in the source code

[prisma shard]

wait wtf, isnt hearthstone literally a unity game

and genshin

[naive pawn]

it's not 1:1, and it's made harder when there's more compilation or optimization or translation layers or obfuscation. but it's never impossible

[sour fulcrum]

In regards to if thats how update works, yes. In regards to help with some specific problem you might have with this, it's a little hard to get the gist of it just by reading it. you might need to do some troubleshooting (eg. some debug logging) to narrow down what's going on

also in the future post your code via

[prisma shard]

Oh so its not really decompiling its reverse engineering?

Ah, thanks, I'll format better next time

Does it count as decompiling if i am analyzing the behavior of a famous game and duplicating the behavior into my game

[brisk robin]

The issue I'm having is a flash of white due to the text staying really big relative to the new canvas. Like, the letters are taking up the whole screen. I don't see why they WOULD, if I'm disabling the textbox and making the text smaller on one frame, then turning the textbox back on on the next frame

[naive pawn]

(i see your question about the if's was already answered, so this is more probing into code quality)
why do you need them to be on separate frames?

[naive pawn]

no, that's reverse engineering and/or plagiarism and/or inspiration

depending on how charitable you want to be and how close you're going

[brisk robin]

having the two functions work on separate frames was just one of my attempts at fixing the flash of white. Originally it was just one frame, but I've tried a few solutions that don't seem to be working

[naive pawn]

ah ok

(if you want help with that you'll probably have to give some more context and show hierarchy setup, also see https://xyproblem.info )

[brisk robin]

Well, knowing that I understand the update function running those on two separate frames was a big help. I just wanted to make sure I'm not crazy. I have other ideas for potential solutions, just wanted to make sure I understood that part for troubleshooting

[sage mirage]

Hey, guys! There is a problem I have with references when changing scenes, basically I want to assign references at runtime when changing a scene and using DDOL for specific singletons I have. I have heard about Service Locator Pattern & Dependency Injection. Could you please help me understand what they do like the logic and also what are the pros and cons and whatever?

[ivory bobcat]

These patterns aren't unity specific

[obtuse hollow]

I mean, it depends on what you want to do. If I have singletons, then I just make a container class, with statics to those classes that are singletons, and just acess them whenever I need, without creating any references in non singleton classes.

But I dont have to care about any safety and "pretty" code since im solo so im doing whatever I want lol

[sage mirage]

I dont think you are experienced enough then

[sage mirage]

That goes for you

If you dont think about refactoring and better optimization techniques etc then you are not good at programming and not experienced

I always think about better architecture etc

[obtuse hollow]

Not really, my code is pretty performant and im quite good at programming, the thing is that if you are solo, you can do whatever you want, no reason to do boilerplate code, keeping things simple always beats complex solutions if they are not sucking up performance

[sage mirage]

Its not about writing code we can all write code the hardest part is how you connect everything and making a clean architecture. So, my point of view is recognizing which pattern is most effective on a specific software design issue you have as a programmer and actually understanding which Data Structure is better to use for a specific problem because this all has to do with Time & Space Complexity at the end of the day if you dont care about all of that then you dont care about your code and if you dont care about your code you will have many issues because when the project is getting bigger and bigger you wont be able to maintain XD

[sour fulcrum]

they didn't ask

[sage mirage]

Bro even as a solo doesn't matter if you do it solo now, you will be doing it with a team in the future

The point is you have to always apply best practices even as a solo because if you apply them as a solo dev you will be able to apply them with a team as well

I dont have to wait until I start my work at a company or a team in order to learn Github. I am learning Github even as a Solo Dev because I want to learn the Workflow and get more experience handling merge conflicts and versioning my code its the same thing on this one we are talking about.

[obtuse hollow]

Aside from the fact that I dont intend to bring any other programmer to the projects (so I might bring someone from graphics for example), ignoring stiff patterns doesnt mean forgetting about optimizations. It means doing stuff with common sense. Most of the time Im doing patterns without even knowing it, but I do not care if I do them or when I should apply them. Ease of use first if the code is not performance critical, performance over anything else otherwise.

[sage mirage]

Ok anyway my question was about DI and Service Locator Pattern

[obtuse hollow]

And I anwsered you how I do things, and you tried to do... I am not sure what exactly

[sage mirage]

But like the other guy said this is not Unity Specific maybe I have to ask it in programming server

[sage mirage]

What is this you mean?

I want to understand the DI and Service Locator so probably I am gonna ask and search for them

[twin cloak]

I think both of them are really good but from my experience different people handle better different solutions.

I am personally more of a DI guy,
So in my unity project I have one single entry point and that is giving control to everything, including every manager and systems that are relevant to the pillars of the game or whatever you wanna call it
so all my systems and different parts of the game already know each other from the very beginning.

in most multiplayer systems they use a service locator, which is quite a different pattern,
in my own systems I don't use a service locator because I already have one main entry point which tells everyone which reference to get,
but I can still work with reference locators of other systems.

The only way for you to know which one you like most is to just try each and eventually see which you like more

the general appraoch in unity is to expose references in each script where you need, and manually assign through the editor.
Only use these for stuff you know you can't get through the editor or have a good reason for

[sage mirage]

Currently, what I do is I have two bridge game objects like TitleSceneBridge and MainSceneBridge and I have a script for each of them a TitleSceneBridge script and MainSceneBridge script as well. So, when the player is changing a scene I am manually assigning the specific references I need on the other scene.

So I am assigning references I need at runtime

when the scene transition happens in awake if I am not wrong

[ionic zealot]

Hi yall, I dont know why, but the resolveshot func doesnt seem to be getting called, please help https://codeshare.io/GkYbkw

[sage mirage]

Hey, guys! If I want to stop a coroutine within a coroutine I have to do something like

{
    while (true)
    {
        if (GameManager.Instance.CurrentGameState != GameState.Playing) StopCoroutine(SpawnLivesDelay());

        yield return new WaitForSeconds(spawnLivesDelay);
        SpawnLivesAtRandomPoints();
        yield return new WaitForSeconds(spawnLivesDelay);
        ObjectPoolManager.Instance.ReturnObject(LIVE_TAG, SpawnLivesAtRandomPoints());
    }
}```

because it doesn't allow to use return within a coroutine

So, I can just use StopCoroutine right?

[ivory bobcat]

Why not just use the break statement to escape the while loop and exit properly?

[sage mirage]

oh yes

XD

[ivory bobcat]

And you'd want the coroutine instance, not the coroutine function (if you're really wanting to stop it)

[naive pawn]

you would use yield break to stop an IEnumerator, that's the analogue of return in this context

(but yeah you can just break the loop if it's on a loop)

[sage mirage]

oh yield break I will keep it in mind

[cosmic dagger]

yes, it is best to store the Coroutine in a variable, so you can use StopCoroutine(coroutineVariable) . . .

[sage mirage]

{
    int rand = Random.Range(0, 6);
    GameObject live = ObjectPoolManager.Instance.GetObject(LIVE_TAG);
    live.transform.position = spawnLivePoints[rand].transform.position;
    return live;
}

public void SpawnEnemiesAtRandomPoints()
{
    int rand = Random.Range(0, availablePoints.Count);
    GameObject enemy = ObjectPoolManager.Instance.GetObject(ENEMY_TAG);
    enemy.transform.position = availablePoints[rand].position;
    enemiesAlive++;
    availablePoints.RemoveAt(rand);
}

public int EnemiesToSpawn(int wave)
{
    int enemies = 1 + wave / 3;
    if (enemies > 4) enemies = 4;
    return enemies;
}

public IEnumerator SpawnLivesDelay()
{
    while (true)
    {
        if (GameManager.Instance.CurrentGameState != GameState.Playing) break;

        yield return new WaitForSeconds(spawnLivesDelay);
        SpawnLivesAtRandomPoints();
        yield return new WaitForSeconds(spawnLivesDelay);
        ObjectPoolManager.Instance.ReturnObject(LIVE_TAG, SpawnLivesAtRandomPoints());
        yield return new WaitForSeconds(spawnLivesDelay);
    }
}```
Now, I have another issue. If you can help me figure it out maybe. So, the problem is that my power up doesn't disappear after the X seconds so the power appears and then after X seconds doesn't disappear.

On my SpawnLivesDelay() coroutine there is a problem and I dont get any errors.

Oh

The problem probably is that I dont store the reference to a variable when returning the value from the method

@ivory bobcat Why you erased your reply message?

[naive pawn]

SpawnLivesAtRandomPoints gets a new GO from the pool.

you then immediately return it

if you want to return a GO that has previously been allocated, you need to have a variable for it, and then return that

[ivory bobcat]

I misread. I thought that the problem was solved..

• Verify the delay value
• Make sure that the despawn instruction is called
• Make sure that what's being despawned is the correct object

[sage mirage]

it was solved

The problem was that I didn't store the reference to a variable

[ivory bobcat]

You should cache the spawned object before the second wait statement and despawn that object instead some other new random object

[sage mirage]

This was the problem and I figure it out

{
    while (true)
    {
        if (GameManager.Instance.CurrentGameState != GameState.Playing) break;

        yield return new WaitForSeconds(spawnLivesDelay);
        GameObject live = SpawnLivesAtRandomPoints();
        yield return new WaitForSeconds(spawnLivesDelay);
        ObjectPoolManager.Instance.ReturnObject(LIVE_TAG, live);
    }```

Thanks for the help btw !

[twin cloak]

since you will probably be testing stuff from different scenes, I'd make a singleton where in the static getter you make a new gameobject if none already exists, and return that (or the existing one) + you can give it dontdestroyonload if it's important that whatever you need in the second scene be the same instance

[naive pawn]

if a function returns a reference type and is not idempotent, then X() is often not the same as X()

[sage mirage]

I do use DDOL and Singletons yes

The problem is I dont want to touch right now anything because I dont want to break my code

[twin cloak]

what do you mean

[sage mirage]

and my project basically because I have chosen to create bridges and actualyl assign references I need manually

[twin cloak]

I think I don't understand what is the issue that you are trying to solve with these patterns

[sage mirage]

I am sure you dont understand

It's dependency + references + scene transition issue

because I have managers on my first scene

an d I want to assign references I hve on my other scenes

and I use DDOL and bridges like I said to do so

its not an issue basically

its just about better maintainability and flexibility

Its not a problem I can continue working with this method

How I am supposed to help you understand?

Just guide me

Can I provide 3-4 important scripts I have there TitleSceneBridge, MaiNSceneBridge and 2 others maybe

I want you to see and unerstand

im having trouble with the xri button inputs, the grips, triggers, and joyssticks all have their own input action but the primary and secondary buttons do not. Is there something I am missing or do i have to manually assign these.

[grand snow]

I want to warn you that its not a good idea to use a scriptable object for more than data storage because unity may unload and make a new instance at some point

any old class can be used for this but if you are having issues with dependency management perhaps a DI framework or your own DI system may help

[misty sand]

    {
        if (ceilingLightMaterial != null)
        {
            ceilingLightMaterial.SetColor("_EmissiveColor",
                on ? emissionColor : Color.black);
        }

        if (corridorCeilingMaterial != null)
        {
            corridorCeilingMaterial.SetColor("_EmissiveColor",
                on ? corridorEmissionColor : Color.black);
        }
    }``` I cant figure out why my emission materials for the corridor wont change to black like the main ones do when they should

i cant put the full code in

[timber tide]

Is this a reference problem or more of a rendering problem

if reference problem, understand what the sharedmaterial property is on your renderers

https://docs.unity3d.com/ScriptReference/Renderer-material.html
And read the docs on that a bit more

[misty sand]

to be honest i couldnt tell you, im not too sure.

[wintry quarry]

Are you at any point using .material on the light renderers? How did you get the reference to the ceiling light material in this script?

[feral scaffold]

how i can verify the ration of white/black in a render texture?

[wintry quarry]

Can you give more context? The most straightforward way is to iterate over the pixels and do the math

Are you trying to figure out how "bright" the image is?

[feral scaffold]

no my render texture is used for a mask in a shader and i want to know how much of the render texture is erase

[rich adder]

on what?

i have visual studio and i alredy modified it to work with unity

[wintry quarry]

you shouldn't need to convert anything to anything - you can iterate directly over the pixels in the RT.

[feral scaffold]

but i don't find how

[rich adder]

what do you mean "modified it to work with unity"

if its not working like image 1 then its not

[feral scaffold]

desactive the game object if the render texture have like 70% of black

Does anyone know what happened? My Unity project just reverted its scenes back to a few weeks ago and all of my work in that scene got erased

[wintry quarry]

Are you using version control and/or onedrive or dropbox or something

[feral scaffold]

Color32 is the same as Color?

[wintry quarry]

[wintry quarry]

that was for Anacondra

[fading marten]

I do have oneDrive

[wintry quarry]

is your project inside OneDrive?

[feral scaffold]

mb

[fading marten]

yes

I made another scene today, then when I went back to the other one that one was reverted

[wintry quarry]

Well first off - this is a really bad idea

[wintry quarry]

Second - this sounds like you never saved your original scene OR OneDrive rewrote it from the cloud

Stop using OneDrive and switch to a proper version control system.

[fading marten]

ok hang on, I made a demo version of the game and that one is saved

am I able to edit that demo version?

[solar hill]

if you have the project itself and not just the game then yes

[fading marten]

I have the build

can I edit the build?

[sour fulcrum]

no

[wintry quarry]

This is kinda like asking "if I modify this cake will that modify the recipe?"

you mean asset rippers? Probably. It's against the rules of this server to really talk about them. But that's a really silly thing to even think about for your own project

[rich adder]

You can decompile a binary but it won't be the same or guaranteed to do so

[sour fulcrum]

in most cases it's more trouble than it's worth

[wintry quarry]

yeah you will spend more time trying to sort out the spaghetti mess it gives you than just redoing your scene.

[rich adder]

take it as a hard lesson into using a proper version control from now on and ditch that malware called microshit onedrive

[fading marten]

but how can it change just from going to a different scene?

[wintry quarry]

if the other scene isn't saved to the filesystem, then unloading it from memory means it goes poof.

[fading marten]

but I've closed this project hundreds of times and it hasn't gone poof

[wintry quarry]

OneDrive probably overwrote it

why don't you check the history of the file in OneDrive?

Doesn't OneDrive maintain file history?

[fading marten]

I didn't even know it was in OneDrive

it was apparently in my personal section

I don't know how to check fileHistory

Do whatever you want with it

call a function

like make a function that takes the percentage and decides whether to activate or deactivate the object

Architecture questions

[toxic spoke]

how to make cube explode into a million pieces

[rich adder]

find a mesh fracturing asset or build it yourself

or you need to make it pre-cut yourself and have 2 versions

[midnight tree]

||Create the million pieces that fly apart from the explosion||

[rich adder]

You can fake it also using things like VIsual Effects graph

it really depends on the usecase

[toxic spoke]

what if i make a million cubes and then make a rigid body explosion

[rich adder]

thats a way to do it sure

essentially 3 ways.. not including generative ones like voxel and mesh deforming algos
pre-fracture (most common)
fake it with many cubes
or simulate it with particles

[toxic spoke]

or put a boom texture on it and then seperate it to a million pieces

[midnight tree]

If you make a million cubes, there will be huge problems with optimization.

[toxic spoke]

then connect 200 playstation 3's together

[rich adder]

at the end of the day it comes down what performance cost you're willing to tolerate for the endgoal.
in most cases the player wont care (if doesnt affect performance)

let's say I want a learning hint to appear only once when player interact with a thing

making a bool check is easy but is there anything smarter than that?

I thought of making a delegate and assigning it depending on if bool is true or false on a Awake

so you don't waste performance for bool check

I mean in this context bool is either this thing have been shown or not

[cosmic dagger]

a delegate is more expensive than a bool . . .

[real thunder]

you do a bool check each time you do the interaction tho

while delegate assigned once

anyway is there a saner solution?

[cosmic dagger]

a simple bool check does not waste performance. it's literally a bit check . . .

[sour fulcrum]

delegate type stuff might make more sense from a code architecture point of view (maybe) but yeah not for performance

[cosmic dagger]

wouldn't you have to check if the delegate is assigned?

[real thunder]

I dunno how does it work under the hood

I am assuming if it's assigned it's called or u get an error in case it's not

which is not a check?

I actually saw a code doing a delegate thingie instead of, well, not bool but an enum check which is prolly more expensive than bool check but still

[cosmic dagger]

well, by default, most people would check the delegate before using it to avoid the error, no?

[real thunder]

why would I

if it's assigned once on Awake

and Update can't run before that

[sour fulcrum]

You would be unassigning from the delegate once the tip is shown?

So it’s only shown once?

[real thunder]

I d reassign it that moment yes

I d still save the bool about it and each game opening

choose a delegate with check or without check

[sour fulcrum]

no that’s psychotic

[real thunder]

laughs diabolically

but like seriously isn't it better

[fading marten]

I don't know what to do

[swift crag]

This will be strictly worse

Calling a method is significantly more expensive than branching

A delegate that’s null when you don’t need to show the tip is probably equivalent

[grand snow]

something something branch prediction

[ivory bobcat]

Not needing to poll the state would probably be what you'd want but depending on context, it may be more convoluted and better just to have a simple conditional branch. What exactly is this solving? Unnecessary complexity is generally not preferred.

[cunning bramble]

Hi guys,
Does a Website or what every exist where i can see c# or Unity related code that i need to fix because i wanna get better

[fickle plume]

You can make a post in #1390346827005431951 with a Code review tag and someone might take an interest to answer you. Should make sure your code is well commented and illustrated with relevant component screenshots probably as well.

[pearl isle]

hi guys ! I'm trying to follow a tutorial in which my sprite has to be a child of my text; unfortunatly in doing so, my text disappears (my sprite gets rendered before my text as following the hierarchy.). Unfortunately, the Canvas Renderer is useless because all I can do is click the Cull Transparent Mesh button. Is there any way to fix this issue ?

[fickle plume]

Canvas has Image component to render pictures.

[pearl isle]

Im afraid I cant edit the canvas seeing as im working within a prefab

[fickle plume]

You should ask a full question with all details in #📲┃ui-ux

Oh alright, thank you ! Sorry for the bother

[real thunder]

I meant using the whole interaction method as a delegate, not inserting a delegate into it
Is calling a delegate more expensive than calling a method?

[real thunder]

I just feel like there should be some way to remove useless bool checks since you know at the begninng bool will never change
buut I see, branch prediction makes it basically pointless

guys... is it a good idea to remake the whole nav mesh, and replace it with way point? Because of the player movement being so goddamn complex, the enemy appears to be extremely dumb, so i want them to be able to jump, wall run, wall jump, even ceilling running.

And the player movement is walking, running, jump, 2 air jumps, wall run, wall jump, while running on the wall we can go up or down, ground slam.

[real thunder]

it's "just make your own engine" category of a good idea

[elder hearth]

Hi! I was wondering if there's a way to make it so I don't have to set my bools back to false after an input toggles it to true?
So this is the code to read the input and set a bool to true

        void OnCrouch(InputValue value)
        {
            CrouchIsPressed = value.isPressed;
        }

and after this in the script(s) that read the bool I have to set it back to false!
So

            playerManager.CrouchIsPressed = false;

[gloomy vine]

Why I can't see the blue surface of the navmesh?
I have gizmos enabled, "show navmesh" set to true, baked the mesh

[stark helm]

How can make it so that I have a function that I can acces from any script?I dont need the function to be in a physical object tho

Interfaces dont seem to be it

so what can I use to achieve that?

[elder hearth]

Can't you just make it a public function and public class?

[stark helm]

yes but how do I reference it from a script?Because I need an object for that

[gloomy vine]

well there is like 100 ways to approach this depending on your needs

you can create a new instance of that class in ur script for example

[elder hearth]

That is also true

[gloomy vine]

or just use static

[elder hearth]

you can also make it static

[gloomy vine]

or dependency injection

[elder hearth]

a regular C# script

[gloomy vine]

and so on

[stark helm]

I will try those now

[elder hearth]

I'd recommend searching it up, these are some basic OOP principles

Especially in C#

[gloomy vine]

exactly

[elder hearth]

Honestly I can't beleive there are non OOP langs, it would be absolute HELL for me

I love my OOP langs

[gloomy vine]

bumping my question

[stark helm]

@elder hearth Would this cause lag?

[elder hearth]

Why would it?

[stark helm]

it creates another script no?

If I have 100 of those it would be laggy?

[gloomy vine]

it creates a new instance of a class

and no, this wont be laggy

u can spawn million of these

and it wont be laggy

[elder hearth]

Exactly

[stark helm]

how do I reference a GameObject in the Hitbox_Module? Grabbing and dragging won't work, do I use scriptable object?

[queen vale]

transform.Parent, GetComponent, etc.

[stark helm]

The Hitbox_Module isnt attached to anything

its just there

[elder hearth]

It will still work

[stark helm]

so I use scriptable object no?

[elder hearth]

No

[stark helm]

Ima try then

[elder hearth]

It calls a reference of it

[stark helm]

thanks it does work

That is all guys

thanks

[elder hearth]

No problem!

[thick garnet]

Does anyone know a platform for laypeople who want to learn coding to make games for beginners?

[night raptor]

Waht kind of platform are we searching for here? Game engines, learning platforms or something else?

[thick garnet]

Platform for learning to make games and a platform for making games

[night raptor]

There are a lot of game engines. Unity is among the better to get started given how much resources about it are freely available online. Unity Learn I have heard is a good way to get up to speed with Unity.

[sage mirage]

Greetings game developers 👋

So, I came up here with a problem in my shoulders/back. So, the problem is that I am trying to randomly choose 1 of 2 tags I have for 2 power ups and I want to store this random value on a variable.

There aren't string parameters for Random.Range() and I really would like to have some help 🙂

So, the problem is that I want to actually spawn a random power up at specific spawn points but I have to choose between those 2 power ups randomly

and now I am thinking how to make it work XD

[night raptor]

Generate a random number and compare

[sage mirage]

{
    int rand = Random.Range(0, 6);
    GameObject powerUp = ObjectPoolManager.Instance.GetObject(LIVE_TAG);
    powerUp.transform.position = spawnPowerUpPoints[rand].transform.position;
    return powerUp;
}```

This method was working when I had only 1 power up

now I have to do the above

[night raptor]

If you want equal chance, get a random int between 0 and 1 lets say and make 0 yield the first power up and 1 the second

[naive pawn]

array -> generate index -> index array -> random non-numeric value

a bit more complex if you want weights, but it's the same general idea - have a mapping between things you can randomize (numbers, discrete or continuous) and the outputs you want (arbitrary discrete values)

[sage mirage]

wait key value pair maybe?

HashMap

yes

[naive pawn]

no

[night raptor]

I wouldn’t do that. Array is already index to item mapping

[sage mirage]

oh shit I got confused with this a bit let me brainstorm a bit

[naive pawn]

mapping does not mean a Map structure

a mapping is just an onto function

i love how we give direct answers and then you extrapolate to make it both more confusing and complex

[night raptor]

I mean it would work but is just not required nor is it as efficient

[naive pawn]

would be more fragile and more work to add/remove elements

[sage mirage]

By the way, I did it like this too simple no hash maps or anything just an array.
```public GameObject SpawnPowerUpAtRandomPoints()
{
int randPoint = Random.Range(0, 6);
int randTag = Random.Range(0, powerUpTags.Length);

    powerUpTag = ChooseRandomPowerUps(randTag);

    GameObject powerUp = ObjectPoolManager.Instance.GetObject(powerUpTag);
    powerUp.transform.position = spawnPowerUpPoints[randPoint].transform.position;
    return powerUp;
}

public string ChooseRandomPowerUps(int randTag)
{
    string powerUpTag;

    if (powerUpTags[0] == powerUpTags[randTag])
    {
        powerUpTag = powerUpTags[0];
        Debug.Log("Power up is: " + powerUpTag);
    }
    else
    {
        powerUpTag = powerUpTags[1];
        Debug.Log("Power up is: " + powerUpTag);
    }
    return powerUpTag;
}```

and if I have more powers ups I wont make if else if all the time, probably I will have check each element in the array and compare it with the rand tag

using a for loop lets say

[broken nest]

kinda noob question but how do I rotate an UI element?

Through code obviously

[sage mirage]

You have to use its Rect Transform in order to rotate it there is Rect Struct in Unity you can use in this case

https://docs.unity3d.com/6000.4/Documentation/ScriptReference/Rect.html

[broken nest]

connexionImages[i].GetComponent<RectTransform>().Rotate(new Vector3(45f * connexionList[i].connexionDirection, 0,0)); Like that?

I want to apply an angle according to an int

around the z axis cos i'm in 2D obviously

[sage mirage]

I am not 100% sure but if you want Angles you have use Quaternions

Not a vector

[broken nest]

The Rotate function uses a 3 axes of rotation system called euler angles

[sage mirage]

yes it is quaternion.Euler

or euler angles specifically

[broken nest]

I'm not too familiar with how it works but yeah it takes a Vector3

Never used RectTransform.Rotate() we'll see if it works

[sage mirage]

I am not really familiar as well to tell you I am practicing a lot and Game Math is hard concept

[sharp bloom]

Isn't "game math" mostly just linear algebra?

I'm not the best at it but it's kind of fun when you start to "get" it

[sage mirage]

Linear Algebra yes and Boolean Algebra there is also statistics and more its not just linear algebra of course not.

statistics and probability are everywhere in AI like steering behaviours and more advanced systems I think

[woeful scroll]

hello can i send a vid to ask about some stuff and wanting some advices??

[sage mirage]

not here

if its unity specific yes

[muted sand]

it's mainly geometry & math functions as far as I know
And ofc there's physics

Mainly

[woeful scroll]

yes it is unity 2d

it is unity 2d but like ability system

[sage mirage]

go

what is it

[woeful scroll]

it is more like a show case but anyway. i have made this can anyone give any advice(except the asset, currently i have none, players are using lpc), and about the vid quality, had to compress it for <10mb limit.

[sharp bloom]

Fortunately Unity does lots of heavily lifting when it comes to physics. There are some strange behavior with it though, for example one time I was making a pendulum using real formulas, and for some reason the system kept gaining small amounts energy for some unknown reason

[muted sand]

I can't be bothered with allat
I'm figuring out input system right now and how to control it

[sharp bloom]

Yeah the answer I got was pretty much "Unity is not meant for perfectly real-world physics simulation"

[elder hearth]

Hi! So I have this if statement

  if (grabbed == true)
  {

      this.gameObject.transform.parent = grabber;
      this.gameObject.transform.position = grabber.position;
  }
``` and the line 

  this.gameObject.transform.position = grabber.position;

[solar hill]

how are you verifying that "grabber" isnt null, what even is grabber in this context?

[polar acorn]

If the error says grabber is null then it's null

[solar hill]

is it declared as a gameobject?

[elder hearth]

THe first line isn't returning null

[elder hearth]

But the first line isn't returning null

[solar hill]

can you answer all the questions, how is grabber declared?

is it "public GameObject grabber;"

[elder hearth]

its is Transform grabber;

[solar hill]

how did you assign the reference?

through the inspector or through code?

[polar acorn]

Which line? The if statement or the parent assignment? Neither of which confirm grabber is assigned

[elder hearth]

this.gameObject.transform.parent = grabber;

[polar acorn]

That line runs completely fine if grabber is null

[elder hearth]

Through code, an interface to be exacr

[polar acorn]

You can assign a parent to null, that's how you unassign a parent

[elder hearth]

exact *

[polar acorn]

Grabber is null

[elder hearth]

I can?

Oh

i did not know that tbf

[verbal dome]

It is just Transform.Rotate.
RectTransform inherits from transform. It's the same as adding that value to the euler angles of the transform, nothing fancy.

[verbal dome]

Thats likely a side effect of floating point imprecision. Small errors add up and some energy might be lost or created from nothing

Not sure if the other physics backends are better at that

But maybe

[sharp bloom]

async void SomeMethod()
{
  await SomeRecursiveMethod();
  print("recursive function is finished!");
}

async Awaitable SomeRecursiveMethod()
{
  if (some condition) { 
    await Awaitable.WaitForSeconds(1)
    "(do something...)"
    await SomeRecursiveMethod()
  }
  else ( "(somehow mark function as complete?)" )
}

Is it possible to achieve this type of behavior with async/await? (Calling a recursive function and somehow waiting till its done recursing?)

Or is this a bad idea?

Because I'm pretty sure the print would happen immediately after the first "WaitForSeconds"

[sharp bloom]

Oooh that would explain it

[verbal dome]

Mark function as complete, wouldnt that just mean returning?

await makes it wait for the method to finish until continuing to the next line

So you'd see the print only after everything in the recursive method finishes

[sharp bloom]

So it does work like I thought huh

I was afraid that this line would immediately make the function count as "complete"

[verbal dome]

Nope, it just pauses for that duration

[sharp bloom]

I see

[turbid jolt]

hello idk if this is the right channel but i am stuck for my assisgnment im supposd to make a tank game, im following this tutorial to make my tank shoot: https://www.youtube.com/watch?v=1rohOpl9Tq4 , it pops up with this error no matter what i do wether i have the bulletspawn and bullet attached to the tank turret or not, one difference i noticed between mine and the video is:

mine does not have this

i cant connect the bullet spawn to the bullet

[grand snow]

READ the error and observe whats missing

See how it even told you its on line 21?

[turbid jolt]

ah i completely missed that ty

let me retry

[grand snow]

Once fixed it should recompile and show changes you made

[broken nest]

I have this old piece of code and I can't remember how it works,

[System.Serializable]
public class UnityCustomEventIntBool : UnityEvent<int, bool> { }

public UnityCustomEvent customEventIntBool;
customEventIntBool.Invoke()

Will it call the method I put in editor with a bool and an int as parameter?

[turbid jolt]

i tried to change it from the rb thing i had before (as it said that was an issue) but now it pops up with this which idrk what it means 😭

[swift crag]

The first two lines are only necessary for older versions of Unity. It used to not be possible to serialize generic types (save for some exceptions, like List<T>) directly

You had to create a class that derives from the generic type, then serialize that class

Invoke is going to want two arguments (the int and bool values to pass to whoever has subscribed to the event)

so you'd do something like customEventIntBool.Invoke(100, true);

[grand snow]

First line is correct! Second line should use rb

You are trying to use the type name

[broken nest]

How do I pass a parameter from editor then?

[swift crag]

i'm not sure what you mean by "from editor" here

your example shows you invoking the event via a script

[turbid jolt]

OHH i get it now that you mentioned that ty!! it works perfectly now

[minor pawn]

first line (line 28) defines a new variable with the type RigidBody with the name rb, the second line (29) should then edit the linear velocity of that variable like this: rb.linearVelocity = velocity;

[turbid jolt]

fab ty!!

[grand snow]

If needed brush up on c# syntax

[swift crag]

Rigidbody is the concept of a physics object; rb is a variable containing a specific physics object

[turbid jolt]

yeah i definitely need to work on it more

[turbid jolt]

that makes sense

ty

[broken nest]

Bruh I've been coding for 3 days without touching editor and somehow the editor had warnings pop up at least 5 times what is wrong

[minor pawn]

do you mean just opening the c# scripts in vsc or smthin without unity open?

[broken nest]

I mean I'm coding on visual studio and Unity has bugs when i don't touch it

I have the recommended version is there that much bug? My project is almost empty

[swift crag]

what are these warnings?

[turbid jolt]

me again, after the scripts and stuff added although works wonderfully you can see the 1st bullet is kind of stuck in place, if i dont move the tank at the beginning and shoot it, it goes at a very high angle, but if i move it then it bugs like in this video and stays still, however the clone bullets that come afterwards when i press space shoot exactly how i wanted them to so idk why the first one is like that basically compared

[twin pivot]

sometimes the unity engine just sends random errors, if it compiles u can just ignore it

[broken nest]

Alright

[devout otter]

scripts are part of unity, if youre making changes to scripts - youre making changes to your unity project

[smoky breach]

How can i make an attribute sum 1 each time a condition its true? currently it just keeps adding 1 to the total per frame the button is pressed

[wintry quarry]

Update runs once per frame. If you don't want to do it once per frame, don't do it in Update

instead, do it whenever you actually want to be adding 1

"each time a condition its true" is really vague

[smoky breach]

example i have
if (isAttacking){combo +=1;}

[wintry quarry]

how often do you actually want that to happen?

You need to provide more context here

Maybe show your code

[smoky breach]

its in a function i call inside update, its a combo counter, so each time you press the button it adds one and then reset after a time

[wintry quarry]

So when do you want to add one?

When you press the button?

There still isn't enough information here for me to give you practical advice

[minor pawn]

is it possible that your cloning a bullet thats acctualy in your scene and not a prefab?

[smoky breach]

I had to change the combo count to just be equal instead of adding, but i realized i'm going to need to add to it instead of just hard coding the value for future use

[grand snow]

that single line if is a crime

auto format that shit

[wintry quarry]

There's a lot that's problematic here

and yeah the least of it is the formatting

is this code run unconditionally in Update? It's not clear what's going on here, and I think parts of this need to be separated out.

• Some of it should only be running when you press the button
• Some of it should be running in Update

[turbid jolt]

ohhh i think thats it yes

[wintry quarry]

What happens when you try? And where exactly are you dragging them?

[fading marten]

my cursor turns into a prohibition sign, and I'm dragging and dropping from file explore

[cosmic quail]

you cant drag from zip files

[wintry quarry]

Where are you trying to drag TO inside Unity?

[naive pawn]

does it happen with other files?

[fading marten]

its not in a zip file

[wintry quarry]

Are you dragging into the Project window, or elsewhere?

[fading marten]

yes

I'm trying to put it into a folder

[wintry quarry]

A folder inside Assets, right?

Not in Packages?

[fading marten]

yes

[fading marten]

yes

[naive pawn]

well people have gotten that before but i don't remember what it was or how to fix it

[wintry quarry]

What happens if you just move the file from windows explorer? Like instead of dragging it inside the unity window, just manually move it into the folder you want from windows file explorer

[broken nest]

Why does this monPark[monParkIndex].monsterName = ""; Doesn't work?

{
    public string monsterName;
    public string[] currentSpells;
    public int naturalHealth;
    public int naturalStrength;
    public int naturalMagic;
    public int naturalArmor;
    public int naturalResilience;
    public int naturalSpeed;
    public int currentStrength;
    public int currentMagic;
    public int currentArmor;
    public int currentResilience;
    public int currentSpeed;
}```

public List<MonStats> monPark = new List<MonStats>();```

[wintry quarry]

Can you explain what you mean by "doesn't work"?

[naive pawn]

can you be more specific about how it doesn't work

[fading marten]

that works

ty

[broken nest]

It says that the return value of List<MonStats>.this[int] because it's isn't a variable

I have no problem doing it when it's not in a list or array

[wintry quarry]

It's because it's not an array

You can only use this syntax for structs with arrays

You need this:

MonStats stats = monPark[monParkIndex];
stats.monsterName = "";
monPark[monParkIndex] = stats;```

[naive pawn]

when you're asking about errors don't rephrase/retype the message, copy and paste it directly. you can lose info retyping it

[wintry quarry]

It would also work with your current syntax if MonStats was a class instead of a struct

[broken nest]

My IDE is in french

[wintry quarry]

But the problem with trying to do this with a List is that the indexer returns a copy of the struct

[naive pawn]

https://unity.huh.how/compiler-errors/cs1612 further reading

[wintry quarry]

so modifying that copy would not do anything - and the compiler gives you an error instead of letting you footgun yourself.

[broken nest]

okok ty

ty

[broken nest]

So what do you recommend me do? I use a list cos I want the size to be basically infinite without having to rely on an array. Should i make a class?

[wintry quarry]

I showed you above how to do it

hello im trying use the key pressing system and this error appears

"if (Input.GetKeyDown(KeyCode.Space))" this is the problem line i guess

how can i fix it

[fair cedar]

i think you are doing it like the old input manager

i just swapped to the old input manager

idk if that is good but it was mostly for following tutorials

[placid solstice]

i change it in Player Settings

but, how is the new input manager?

like, the code

[fair cedar]

https://discussions.unity.com/t/help-me-how-to-fix-it/813420

you could use both

[fair cedar]

maybe this https://docs.unity3d.com/Packages/com.unity.inputsystem@1.19/api/UnityEngine.InputSystem.Controls.ButtonControl.html#UnityEngine_InputSystem_Controls_ButtonControl_wasPressedThisFrame

but i am still trying to learn so i am sticking to the old one for now

I am trying to make a smash attack for my game, and the way it works is = press key > jump > land and push nearby enemies away. First it kinda worked only, but the smash attack was doing when i was jumping up not when i was landing, but now when i use grounded bool, it still does the attack when jumping, because I guess the force hasnt really moved my player enough up to not be grounded anymore??? is there a way to delay something by one frame ? ```
if (Input.GetKeyDown(KeyCode.Space))
{
if (canSmash)
{
playerRb.AddForce(Vector3.up * jumpStrength, ForceMode.Impulse);
canSmash = false;
smashing = true;
}
if (smashing && grounded)
{
smashAttack();
smashing = false;
}
void smashAttack()
{

    for (int i=0; i < spawnManagerScript.enemies.Count; i++)
    {
        GameObject enemy = spawnManagerScript.enemies[i];
        Rigidbody enemyRb = enemy.GetComponent<Rigidbody>();
        Vector3 awayFromPlayer = (enemy.transform.position - transform.position);
        enemyRb.AddForce(awayFromPlayer * smashStrength, ForceMode.Impulse);
    }
}

the code is probably bad so any advice would be great

how do i make it so that the smash attack wont do when it has not jumped yet, but when it landed from it?

[next yarrow]

it runs when you jump up because you set smashing to true when space is pressed (which I presume is jump)
right after, in the same frame still, you call smashAttack()

[rich adder]

how you check the ground ?

[next yarrow]

you should keep track of "did the player jump already?"
If they did, only then, when grounded becomes true again, you smashAttack()

hey guys im really stuck on this issue im trying to make it so when the mouse is over a certain object it moves towards one side like left to right i know trasform position exists its more that getting the mouse over a game object or ui element to updates its position

[next yarrow]

what's the problem specifically?

[fresh wadi]

how mouse hovering works

i found a solution but it only worked for text which is a ui element

[next yarrow]

you're asking how to know if the mouse is hovering a gameObject?

[fresh wadi]

yes

[next yarrow]

IPointerEnterHandler should be your answer then

https://docs.unity3d.com/6000.4/Documentation/ScriptReference/MonoBehaviour.OnMouseEnter.html
there's this also, depending on what you're trying to do

[fresh wadi]

ive entered the code that unity has provided documentation for IPointerEnterHandler and attached to a simple 2d square nothing is happening

all i want it to do is when i hover over the mouse over a certain game object it change a variable to 1

[rich adder]

IPointerEnterHandler only works on UI / Canvas by default otherwise it needs a physics raycaster on camera

otherwise you can just use a regular 2D overlap point

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Physics2D.OverlapPoint.html

[fresh wadi]

any kind of collider would work

or is it a spefic component

[rich adder]

which one ?
for overlapoint Physics2D works for 2D collider
Physics class with 3D

hello,

I have currently making a unit movement script and I need to link a layer to the script, I have made a "layerMask" variable, but the "ground" variable is not appearing in the script. Would anybody be able to point out why this is?

Whys that? 👀

also,

I am following a guide on youtube, he is on an older version of unity by the looks of it, my animation screen looks nothing like what he has. Am I on the wrong tab, or has it just been overhalled alot?

[slender nymph]

the left is the animator window, while the right is the animation window. two completely different windows

[keen bridge]

oh i see, how do i open the animator window? i do not see that in the dropdown

[slender nymph]

use the Window menu at the top rather than that context menu

[broken nest]

I have this script database where I store all my scriptable objects. Can I change them at runtime? like sprites and all?

[keen bridge]

thanks, got it 🙂

[slender nymph]

this is really not enough info to go off of. but if you are referring to modifying the properties of a ScriptableObject at runtime, you should ideally avoid doing so because it behaves differently in the editor than it would in a build

[broken nest]

What do you mean by that? I have this script public class DataBase : MonoBehaviour { public static DataBase instance; public void Awake() { if(instance == null) { instance = this; } else { Debug.LogError("more than 1 DataBase"); } } public List<ScriptableObjectMonster> scriptableMonsterList = new List<ScriptableObjectMonster>(); public List<ScriptableObjectSpell> scriptableSpellList = new List<ScriptableObjectSpell>(); public List<ScriptableObjectLevel> scriptableLevelList = new List<ScriptableObjectLevel>(); public Sprite backgroundForest; public Sprite backgroundSavana; public Sprite backgroundIce; public Sprite backgroundTropical; public Sprite grassForest; public Sprite grassSavana; public Sprite grassIce; public Sprite grassTropical; }

[slender nymph]

which part of what i said are you not understanding?

[broken nest]

Can I modify the scriptableObject at runtime

Ah ok

[slender nymph]

if you are referring to modifying the properties of a ScriptableObject at runtime, you should ideally avoid doing so because it behaves differently in the editor than it would in a build

[broken nest]

Then Idk I'll figure something out then

[cosmic dagger]

They aren't meant to be changed during runtime. They are mainly used for immutable data that many objects reference to save on memory and avoid repeated data/values . . .

If you want to mutate or change the data, it's better to use a runtime class and copy the SO data to it, then you would use that—class—instead . . .

[lean sandal]

Hey Im looking for some good beginner courses to learn C# with unity for game design and development, and something that I can use to build some basic games and learn to add some new things to it? Can anyone recommend something please? Thank you so much.

[teal viper]

!learn

[radiant void]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[teal viper]

Also, literally, top 10 results in Google.

[lean sandal]

Thank you I will go do some more of those courses I have done alot of them before and they seemed outdated

they also didnt seem to go very far beyond certain things, or were very scattered idk

[teal viper]

Most of it still applies with minor changes. Mostly api renames or method signature changes.

[teal viper]

Depends on what topic exactly you're I terested in. They can't cover everything. That's impossible.

[lean sandal]

I want to learn all the basics right now of code, then just make some small games to practice, like 2d flappy bird etc

which Ive done those before already I just need something that goes a few steps further

[bold root]

Hi ive spent around 4 hours now in unity (so an extreme beginner) and I dont understand why the game view isnt scaling properly from the scene view. Any insight onto where the problem comes from?

[gusty anvil]

After you have a good understanding of C# I highly recommend checking out a youtube channel called "CodeMonkey" he has a 10 hour course that boosted my skill and confidence an insane amount

[naive pawn]

what do you mean by "from the scene view"? the game view isn't affected by the scene view

is your camera set up correctly?

[bold root]

What im seeing on the scene is not what im seeing in the game view

[bold root]

I dont know what camera means

[sour fulcrum]

theres a camera component on an object in your scene

that controls what your game view is like

the scene view is just for your ability to edit stuff

[naive pawn]

this is normal and supposed to happen

[bold root]

so where do I go to fix it

[naive pawn]

the Camera is the thing rendering the scene into the game view

[bold root]

theres this part saying main camera

[naive pawn]

that's an object and it has the Camera component

[bold root]

but i dont know what im supposed to tweak to change the view

[naive pawn]

if you select that object you can see a preview of what the camera is looking at

change the size of the camera

[bold root]

so theres no auto scale to the objects ive already set up?

[onyx ridge]

fischer random? 😄

[naive pawn]

not sure where you're getting that from

[bold root]

what do you mean i just asked a question

i didnt get anything from anywhere

[naive pawn]

auto scale isn't a thing

[sour fulcrum]

you'll understand when your a bit more comfortable with unity cameras but that would be super hyper specific so no

you could do that with code but

for this you probably just wanna adjust the position of the gameobject that has your camera component

and maybe the size and/or field of view on the camera component

[naive pawn]

(would not be fov)

[bold root]

No i have no idea why the queens and rooks swapped lol I just noticed when you said

[onyx ridge]

😄

[bold root]

how do I do this? i clicked run then i changed the size of the camera to 10, that worked great. Then i stopped it and changed the camera size back to 10 and then when i run, its ruined again

[naive pawn]

if you change it in playmode, it won't save

[bold root]

yes

I made the same change out of play mode and got different results

[naive pawn]

as in the size changes again when you enter playmode?

[bold root]

start with size 5 then change to 10 in play mode

[naive pawn]

not sure what you mean by that

[bold root]

start with size 10

[naive pawn]

ah

check the inspector, see if it's changed back to 5

[bold root]

it shows 10

[bold root]

If i change it to 20 now then it shows this

when I start with size 10

[naive pawn]

while in playmode with this issue, how does the camera look in scene view

[bold root]

this is what im changing on the camera is there another section im supposed to change

[naive pawn]

this should be it

[bold root]

scene view is fine

[naive pawn]

as in, the camera frame encompasses the entire board?

[bold root]

yes

actually it zooms in to the perfect spot on scene view with camera size 10, was a little small on 5

[naive pawn]

make sure you only have 1 camera in the scene, i guess?

[bold root]

but game view doesnt change based on the camera size setting

but when i change the size inside playmode it fixes the problem

[bold root]

this is all I have

[naive pawn]

so make sure those other objects don't have Camera components

[bold root]

which means?

[onyx ridge]

The king and queen are on the wrong colours

[bold root]

yes

[naive pawn]

which part of that are you asking about?

have you gone through unity essentials on unity learn

[bold root]

you said to make sure they dont have camera components

[naive pawn]

do you know what a component is

[bold root]

This is all thats there

the only thing i added was the chess board object with a script to make the board and add the pieces

no camera

[naive pawn]

so do you know what a component is

[bold root]

the parts on the right?

[naive pawn]

sure, i guess

try searching for t:Camera in the hierarchy, to confirm there's only one camera

[onyx ridge]

I think you need to do a tutorial on the unity editor itself 😄

Hiearachy, inspector, components, prefabs, instances, project window, scene view, game view, gizmos etc

[bold root]

thats it just the one

[naive pawn]

make sure the scene is saved i guess

[bold root]

Is there a way to resize the camera with sliders instead of just the size? the shape is all off

If i hover the main camera i can see what its looking at on the scene thats why its messed up, I suppose I could try to make all the objects smaller but id rather just make the camera fit it if possible

[bold root]

X and y numbers individualy would be fine too

[keen dew]

The shape is the shape of the game window or the player's monitor when played in fullscreen. You can't physically change the monitor size

[bold root]

ok so somehow when I change the camera size its changing the scale that my objects render. I will need to look into that

found it, thanks team

[onyx ridge]

Buy a new monitor for each scene in the game 😄

[bold root]

kind of makes it seem impossible to develop for different screen sizes if theres no auto scaling mechanic

[sour fulcrum]

there is but it gets a bit complicated 😅

[ionic zealot]

https://codeshare.io/5Dw7EW Hi yall, I know mixing ui positions and world positions isnt ideal, but i really like how it is right now, though I dont know why it always puts out a 200~ instead of actually varying output, please help

[bold root]

well it doesnt matter how complicated it is it needs to be done no?

[onyx ridge]

maybe one way around it could be to have a background instead of trying to trim the scene for the chessboard to perfectly fit the screen

[tender mirage]

Curious, is there a way to call a function parameter with multiple lines?

//Add keywords
keywords.Add(){ 

    new keyword(new string[] { "armored" }, "Armored", "<sprite name=\"Armored\">", true);

}
;

[stoic mural]

Go for making Chess game is insane👀 complexity systems is not beginner friendly

[stoic mural]

Now i wonder why you write {} instead of ()

[stoic mural]

I think your code in written wrong. And yes there function with multiple parameters and you can make the parameters in multiple lines

[naive pawn]

not like that, no. the {} to set members is for constructors

you can just put a newline after (

eg

keywords.Add(
  new Keyword(...),
  new Keyword(...)
  // etc
);
```if the function allows that
if `keywords` is a List or something like that doesn't allow that, you can just add them in separate function calls

there is also collection initialization syntax, though i don't remember if unity's version of c# allows it

[tender mirage]

I see. I'll definitely do that then.

Thanks for the help.

[naive pawn]

also just btw, types should be in PascalCase, so keyword there should be Keyword.

[tender mirage]

that was just a little typo, no worries there.

else it looked like this before

//Add keywords
keywords.Add(new keyword(new string[] { "amphibious" }, "Amphibious", "", false));
keywords.Add(new keyword(new string[] { "antihero", "anti hero", "Anti Hero", "Antihero", "AntiHero", "anti-hero", "Anti-hero", "anti-Hero" }, "Anti-Hero", "", true));
keywords.Add(new keyword(new string[] { "armored" }, "Armored", "<sprite name=\"Armored\">", true));
keywords.Add(new keyword(new string[] { "bullseye" }, "Bullseye", "", false));
keywords.Add(new keyword(new string[] { "deadly" }, "Deadly", "", false));
keywords.Add(new keyword(new string[] { "Doublestrike", "doublestrike", "doubleStrike", "double strike", "double Strike", "Double strike" }, "Double Strike", "", false));
keywords.Add(new keyword(new string[] { "frenzy" }, "Frenzy", "", false));
keywords.Add()

[naive pawn]

that seems normal

that was just a little typo, no worries there.
you still have keyword in this newer snippet

[tender mirage]

honestly i didn't even catch the lower case k. i was wondering why it was throwing an error

[sour fulcrum]

your not meant to, your IDE is

!ide

[radiant void]

💡 IDE Configuration

If your IDE is not autocompleting code or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code

• :question: Other/None

[tender mirage]

yeah visual studio like 50% of the time isn't throwing errors actively for some reason

ever since i started using the 2026 build

[sour fulcrum]

Also just a random observation take it or leave it but you could potentially automate those long lists of strings

[naive pawn]

regex time wooooo

[tender mirage]

Automation? are you thinking of like using string public methods?

[sour fulcrum]

I mean not specifically, I just mean your variations of those strings could be consistently made via code

[naive pawn]

could just be like /anti[- ]?hero/i

[bold root]

Yea I’m wondering now if I can just yoink the source code from Lichess, implement it somehow, and modify it

[sour fulcrum]

im not regex pilled but if you force lowercase whatever the input is there's only 3 variants right?

1. no space, no hyphen (antihero)
2. space, no hyphen (anti hero)
   3 hyphen (anti-hero)

[sour fulcrum]

probably not no

[bold root]

Why?

[sour fulcrum]

it would be heavily intertwined with lichess's code and also it's not made in c#

[naive pawn]

well, it is open source

[tender mirage]

That would be cleaner but sadly i have a boolean as well which is called isNumbered. Basically you add a number after the keyword and it can output even more possibilities.

[bold root]

It’s open source and free to use, the entire thing is on github

[tender mirage]

It's hard to briefly explain but it's already abit messy

[sour fulcrum]

my comment doesn't imply otherwise

[naive pawn]

the chess logic appears to be in its own repo in ts, which is close to c#

fwiw i'd still recommend making it yourself though, especially if you don't have much experience

it's pretty easy to get lost in a pre-existing codebase

[sour fulcrum]

if you don't have much experience making chess sounds like a nightmare

[naive pawn]

(at least the overall structure, not the specific logic for each piece)

[bold root]

Well I have a pretty complex game to make, implementing the rules of chess seems brutal

[naive pawn]

just so you know what's going on as a whole

[sour fulcrum]

Sebastian Lague has two videos on his adventure making chess in unity, you probably can't use it as a tutorial but he does provide source afaik
https://youtu.be/U4ogK0MIzqk?si=gKrEy24O6F38DMX0

[naive pawn]

as a beginner, understanding a whole foreign codebase to a degree you can integrate it with your own systems would probably be harder

[tender mirage]

Might as well code fishstock while you're at it. 😄

[bold root]

Ideally I would isolate the part about the game actually being played

[sour fulcrum]

that is still like

chess code is really complicated

because of the ai stuff

[bold root]

What ai stuff

I don’t need an engine to analyze games, but that’s not that hard anyways

[naive pawn]

a chess bot

[tender mirage]

Maybe some chess bots have parameters built into them for you to modify.

[bold root]

All you need is the fen for a given position

Which is easy to extract

Then plug the fen into the engine and it tells you the analysis

But I don’t really need that for my use case anyways

I just need a playable game board and to implement all the things you’re not allowed to do

Currently I can move any piece anywhere at any time

[naive pawn]

chatgpt chess

[boreal sonnet]

i give the camera the position of player to follow but it shows the background too how can i fix it?

can anyone tell me?

[naive pawn]

what do you mean by "it shows the background"

that's what a background is...?

or do you mean the background of the scene or something

[fair cedar]

i just use OnCollisionEnter and OnCollisionExit functions in PlayerController script with the collider of the player and ground with ground tag

[boreal sonnet]

see the border ... it show beyond the border and with ui also show outside the border

in scene the camera should only show the inside of the border but the outside of border is also shown

[fair cedar]

that is kind of what I tried to do with the bool smashing, but i am not sure how to keep track if the player has actually jumped up, is looking for a negative velocity a good solution to that?

[ionic zealot]

https://codeshare.io/5Dw7EW Laddy's can anyone help me figure out why screen positions break?

[naive pawn]

btw on line 122, mouse delta shouldn't be multipled by deltatime

anyways which line/method has the issue?

[ionic zealot]

Ohh, okay, Ill change that, ty

void ResolveShot(bool won) Distranced always calculates to about 200~

[boreal sonnet]

can anyone tell what is the issue?

[ionic zealot]

It used to work, but i changed the camera angle a bit and now it kinda all just goes to that

[naive pawn]

have you tried logging reticle.position and enemyScreenPos to see if they're the values you expect?

(also shouldn't this practically be in world units)

[ionic zealot]

What do you mean? Cause i aint sure how to really convert it, but i know checking 2 numbers being within a certain range shouldve worked preety well

[naive pawn]

screen units are in pixels, the same physical distance could have different screenspace distances for monitors of different resolutions

[naive pawn]

so are those the values you expect?

[ionic zealot]

Huh, so how would I do that right?

[ionic zealot]

90~ give or take 20

[naive pawn]

convert the reticle to worldspace and get the worldspace distance

[naive pawn]

you expect all 4 values to be 90?

also shouldn't you be using anchoredPosition for RectTransforms, rather than position

[ionic zealot]

No, just the difference

[naive pawn]

so what do you expect the enemy screenpos and reticle screenpos to be

and do they match what the logs say they are

[ionic zealot]

Well i tried, but that kept failing, not sure but i think its because of like moving of the reticle

[naive pawn]

are you moving the position or the anchoredPosition?

(when you tried anchoredPosition)

[ionic zealot]

Enemy is right, but the reticle isnt really its like 200 off

[naive pawn]

try using anchoredPosition i guess

and make sure you're also using anchoredPosition when moving it

[ionic zealot]

position i think, I dont remember completely, and i cant check cause i wasnt using git back then, only started 2 days ago

[real thunder]

you can try to read screen resolution and use it as coeffs

I was doing something like that successfully

no idea what is the best way

[ionic zealot]

I see

I dont really even need the best way, Im doing this for school and it's not really expected, I just rlly wanna make it nice cause it fun to work on

[boreal sonnet]

in scene the camera should only show the inside of the border but the outside of border is also shown?

[naive pawn]

the game view seems to be aligning with the camera edges just fine?

the scene view should not be affected by the camera setup

[boreal sonnet]

anything ?

i know i even tried cinemachine camera & cinemachine brain but after the game view disappears

[naive pawn]

the scene view is the stuff in the scene, the stuff that exists in the game world
the game view is what a player would see, as rendered from the cameras in the scene
you're free to move around in the scene view, it's unrelated from the cameras that exist in the scene

[boreal sonnet]

i know but the camera position is what is important i change it different aspect ratios . it only show the middle scene?

[naive pawn]

what middle scene

[real thunder]

float half_marker_x = main_rect.localScale.x * main_rect.sizeDelta.x / 2;
float offset_x = offset_sides;
float bulk_offset_x = half_marker_x + offset_x;
void case_right_side()
      {
        float enclosed_y = (Screen.width / 2 - bulk_offset_x) * tan;
        if (screen_location_from_center.y <= 0) enclosed_y = -enclosed_y;
        marker_position = new Vector3(Screen.width / 2 - bulk_offset_x, enclosed_y, 0);
      }

this is a piece of code I use to clamp UI element to the sides of the screen and I absolutely hate it and don't remember how it works

[boreal sonnet]

this ?

[naive pawn]

the middle of the scene?

[ionic zealot]

Thank you

[boreal sonnet]

when ratio is change .you see it in photo

[naive pawn]

what's the issue though

[boreal sonnet]

the camera range

[naive pawn]

this is how it's supposed to work

[boreal sonnet]

i know ..listen when i play the game the camera shows the outside part of the border and that's not how its suppose to work right?

[naive pawn]

the scene or the game view?

the scene has a separate "scene camera", it's not using the one that's in the scene

the one that's in the scene renders to the game view

[boreal sonnet]

the game view is the issue

wait

see the outside of the border the camera shows

[naive pawn]

where's the issue

[boreal sonnet]

thats the issue the position of the camera is concern as it also show it in different ratio

[naive pawn]

the position of the camera isn't changing when you change the ratio

just circle the part you're saying is an issue or something

are you referring to the letterboxing of the game view?

[boreal sonnet]

ok you player 2d game the camera only show the player and border behind it right ?

that i wish to do

[naive pawn]

that's.. not coherent

i have no idea what you're saying

borders typically aren't behind the player

if english isn't your first language, feel free to use machine translations

which border are you referring to

draw a circle around it or something

[boreal sonnet]

the border on playes's left side

[naive pawn]

the level border?

dude you gotta get better at communication

[sour fulcrum]

sorry to interject; i'm being a bit of a dingus tonight and can't figure out what i'm missing here in order to correctly get my voxel positions to be correctly in the bounds like it does when its set to 2

    private void MakeVoxels(Vector3 voxelCount, Vector3 voxelSize)
    {
        int count = 0;
        for (int y = 0; y < voxelCount.y; y++)
        {
            for (int x = 0; x < voxelCount.x; x++)
            {
                for (int z = 0; z < voxelCount.z; z++)
                {
                    Vector3 pos = new Vector3(x * voxelSize.x, y * voxelSize.y, z * voxelSize.z);
                    pos -= new Vector3(voxelSize.x / 2, voxelSize.y / 2, voxelSize.z / 2);
  
                    Gizmos.DrawWireCube(pos, voxelSize);
                    Handles.Label(pos, count.ToString());
                    count++;
                }
            }
        }
    }

if anyone can spot what im goofing on it would be kindly appreciated

[naive pawn]

is this about making the camera not show outside the level's border?

[naive pawn]

(btw you can drag on those int fields, that would probably be easier to test)

[sour fulcrum]

trueee ty

[naive pawn]

also fwiw mp4s would be better than gifs

i can't pause this

[sour fulcrum]

that is very fair, i gotta set that up

[naive pawn]

i assume voxelCount is Vector3(slice, slice, slice) and voxelSize is Vector3(bigCube/slice, bigCube/slice, bigCube/slice)?

[sour fulcrum]

correct, sorry for not sending that

[naive pawn]

where's the origin, relative to that big cube?

ah wait i think i see the issue

[sour fulcrum]

all of this is vector3.zero with no rotation or scale

[naive pawn]

hm wait no i'm not sure it's the cause here, but it could be contributing

you're starting at 0, and you're shifting the pos to account for the center by subtracting, so you'd get some negative results

either start at 1 (and use <=), or do pos += to shift the center instead

[naive pawn]

i see

[sour fulcrum]

ohhh hmm improvement ok

gimmie a sec

[naive pawn]

so i think what i described would make the position consistent, right?

but it'd be offset by half the big cube's size?

since what i described basically assumes it starts at the origin

[sour fulcrum]

on the money yeah

we have consistently offset now

[naive pawn]

yeah you'd shift everything by -bigCube/2 or -count*size/2to get it to be around the origin

[sour fulcrum]

🙏 bless you

[keen bridge]

how should one be commiting changes to github? is there some ui in unity to make commits, push and make branches etc?

or should i be opening a terminal in the projects root and using git cli?

[wintry quarry]

Any git interface you want

I personally use the CLI, or these days claude code.

a lot of people use plugins for their IDE (e.g. Visual Studio)

There's probably a Unity plugin somewhere that adds stuff to the editor, but I think a dedicated git client is usually best.

[swift crag]

i just use the CLI directly

[zenith cypress]

Fork is great (app)

[real thunder]

How would I rotate a transform into a random consistent direction indefinitely?

[frosty hound]

This is how you rotate something indefinitely:
https://docs.unity3d.com/560/Documentation/ScriptReference/Transform.Rotate.html

This is how you pick a random direction:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Random-onUnitSphere.html

[real thunder]

It want Euelers

oh wait I can just

yeah get random V3

why on unit sphere exactly
that will make rotation "even" along axises I guess?
if so, cool

[frosty hound]

Because it will give you normalized (length of 1) vector, which means you can multiply it by a speed value and it will be scaled corectly.

[real thunder]

won't I get valid consistent rotation if it was a non normalized vector anyway

[polar acorn]

You're gonna need to define what you mean by consistent

Consistent speed? Consistent direction? Consistent acceleration?

[real thunder]

won't it fit all those 3?

[frosty hound]

It would be consistent yes, as in, it won't change speed.

But the speed of the rotation is determine by the length of the vector. So if you want to have any kind of control over that, that's why you normalize and multiply it by a speed value.

[real thunder]

oh, that makes sense

I understand now, thanks

Guys I have a gameobject called "falling parts" and in this, i have 8 other gameobjects, everyone called platform. Lets suppose they have a rigidbody but they doesnt fall. When i press a button, they will return to the starter position, and for this reason i have to save their starter position. Can i save the gameobject position that has every object (In this case "falling parts") and set its position to the starter one by doing position = starterPosition? Or i have to use array to get every position of the gameobjects?

[naive pawn]

you don't have to use an array, there's several ways to store multiple values

[open crater]

How

[naive pawn]

if they have rbs you should use rb.position/rotation though, not transform.position/rotation

[open crater]

But can i save the starter global gameobject position in start() and then reuse it later for the respawn or i have to do it for every single item?

[naive pawn]

you could have each object have its own field, you could have an array, you could have a list, etc

[naive pawn]

well you want it to happen to every item, don't you

[open crater]

Yes

[sour fulcrum]

are stackoverflow errors always accurate? trying to do some flood filling type shit and i can't tell if im doing it poorly or wrong

[night raptor]

Don't know how that would be inaccurate by any means. If you are running out of space on the stack, you probably have too much recursive calls in it. Impossible to tell what exactly is wrong with your implementation without seeing the code. It could be something wrong with the termination condition or just the task requiring too much space to fit into the stack.

[sour fulcrum]

that probably answers my question yeah, i'd show code but like i haven't even tried to make it good lol

if it can fail because its filling up too much space and gives up then its probably that

i don't think ? i have like a outright recursion rn

[night raptor]

Stack overflow literally means that you are running out of stack space. Most of the times the reason that happens though is due to something wrong in the code that just fills up the stack indefinitely

So the code would be the first culprit I would look for. One common pitfall in flood filling is that you must keep track of the cells you have already visited (or some other solution to avoid duplicates). If you just blindly always explore in all directions, you will end up in an infinite recursive loop. A cell would explore the one to the right and the one to the right would explore the cell to the left and the cycle would continue until you have enough calls to fill the whole stack

[sour fulcrum]

heard chef ty

i think it wasn't infinite but its very unoptimised and like 216k voxels so

ill do some very basic optimisation and report back 😅

[night raptor]

If performance is the concern, I would recommend considering iterative solutions instead. Everything that can be done recursively can be done iteratively as well. Iterative solutions are many times if not always faster than recursion in C# like langauges. At the same time you get rid of possible stack overflows and makes it easier to debug the infinite loop issues

[verbal dome]

Use a stack or queue instead of recursion

[woven scaffold]

quick question, is there a known way to check if a string of text fits within a text mesh pro rect + margins?

a quick search doesnt show up much but maybe i justneed to look more

i feel like there is a built in way to check some variables but i cant remember what it is

[verbal dome]

Probably this?
https://docs.unity3d.com/ja/Packages/com.unity.textmeshpro@3.0/api/TMPro.TMP_Text.GetPreferredValues.html

Fwiw I googled

unity textmeshpro calculate text size

[woven scaffold]

does that take into account the margins as well?

[verbal dome]

No idea,

[woven scaffold]

welp i geuss we will see in a moment

[naive pawn]

doesn't need to be infinite to fill the stack, just needs to take up enough space on the stack

[sour fulcrum]

ill have to research abit into this since i dont know how iteration based stuff could work for like 3d flood fill stuff so i might be missing out on some sauce

thanks for advices

[night raptor]

That's exactly the reason recursion is often used, it may be easier to understand intuitively. For flood fill though it isn't particularly complicated to do iteratively. You just have to make a stack/queue where you put all the cells you would need to explore later. In a while loop you go through that stack/queue as long as there are something in there, take one cell at a time out of the stack/queue and add all the neighbours to the stack/queue to be explored by later iteration.

[naive pawn]

for depth-first stuff you need something FILO, that can be just a Stack object or the callstack - that's what the recursion achieves

[night raptor]

pseudocode:

stack = starting element
while elements in stack:
    element = get and remove from stack
    #do something with the element
    foreach neighbour of element:
        if neighbour not yet explored:
            add neighbour to stack
            mark neighbour as explored

[naive pawn]

i vaguely recall you have to check if element explored before looping?

gonna have to think about that for a bit

[night raptor]

Now it's inside the loop. Either one works I believe. I like this one better since it doesn't need to iterate over the elements that are already explored

[naive pawn]

yeah it'd reduce a lot of looping

Hi! It's me again lol, but my grab system clips objects into other GOs such as walls

    private void FixedUpdate()
    {
        if (grabbed == true)
        {
            if (this.gameObject.transform.parent != grabber.transform)
            {

                this.gameObject.transform.parent = grabber.transform;
                rb.useGravity = false;
                rb.freezeRotation = true;
                transform.localPosition = Vector3.zero;
            }
            else if ((this.gameObject.transform.localPosition).magnitude >= maxDistanceFromGrabber)
            {
                grabbed = false;
            }
        }
        else
        {
            rb.useGravity = true;
            rb.freezeRotation = false;
            this.gameObject.transform.parent = originalParent;
        }
    }
``` I have tried everything to fix it lol

[sour fulcrum]

Would it be common for not yet explored to just be some hashset that i chuck them into for comparison?

[naive pawn]

yeah

or a bitset, if you have sequential ids, for example

[sour fulcrum]

heard heard

its 1:30am so lemme finish my coffee and then i might mess with this, tyty

[elder hearth]

It works now?

odd

[night raptor]

Which would? Having the check before the foreach instead of within it or having a check to begin with?

[verbal dome]

I think this is better. You avoid adding elements to the stack if they are already visited

(If the other option was to add them always and then continue if the element we pulled from the stack was already visited)

[sour fulcrum]

thats not neccasarily viable though right? depending on the context?

[night raptor]

Yeah that's what I have thought. I have seen a lot of examples do it the other way like this:```py
stack = starting element
while elements in stack:
if neighbour explored:
continue
element = get and remove from stack
#do something with the element
mark element as explored
foreach neighbour of element:
add neighbour to stack

[sonic harbor]

Ello im new to coding guys I dont know where to start

[sour fulcrum]

eg. i want green to flood white, so i need to explore 0 more than once because i'll miss it on the first pass

[cosmic quail]

check the pins for beginner c# tutorials and once you've learned c# enough you can start learning unity at learn.unity.com

[naive pawn]

wdym first pass? as in breadth-first?

[sonic harbor]

aww thank you , btw is there any trading course offered here?

[cosmic quail]

wdym trading?

[night raptor]

I don't understand the example. Flood fill does do the if neighbour explored check multiple times for most cells no matter how you implement it (if that is what you mean?)

[sonic harbor]

trading...

[cosmic quail]

trading what?

you mean programming a trading system for your game?

there are probably tutorials for that on youtube

[sonic harbor]

no stock and forex market one

[polar acorn]

You're really going to have to define what you mean by that

[polar acorn]

This is a Unity server

[sonic harbor]

im new to that too

[sonic harbor]

and what's ut for

[polar acorn]

sir this is a wendys

[verbal dome]

New to defining things?

[sonic harbor]

what wendys

wdym

[polar acorn]

This is a Unity server

the hell you asking about finance for

[sonic harbor]

uhm isn't unity server's all abt learning new things together

[verbal dome]

Unity game engine, just to be clear

[polar acorn]

It's about Unity

[sonic harbor]

ohhhh game engine

[polar acorn]

The game engine

How the hell did you end up here

[sonic harbor]

got it

[polar acorn]

I guess I'm expecting way too much out of someone named "Elon"

[sonic harbor]

i was finding the server i sold in 2021 named unity

[sonic harbor]

uhm u can say that , i dont feel bad

[sour fulcrum]

like in this example, would my code ideally do

0: White Tile, just go to next
1: White Tile, just go to next
3 (i forgot 2): Green Tile, add 1 & 7 to stack (dont add 4 because we are about to go to it?)

[sonic harbor]

@polar acorn before i get started with coding and programming, is there any degree or qualification required or any subject req like physics,chem , maths? quantam physics?

[polar acorn]

A basic ability to read might be useful.

[sonic harbor]

read language like c++ and python am i right?

[polar acorn]

No, like, words

At least at a fifth-grade level

[verbal dome]

Wouldn't your flood fill start at tile 3, not tile 0?

[polar acorn]

So take some time, work your way up to that, then try programming

[sonic harbor]

okk , so what's needed to create ur own coding language and ai agents ?
physics? chem ? mayhs6?

[sour fulcrum]

a different server

we don't do that here

[elder hearth]

Different server, but maths is quite important
