Not sure what you're actually asking

[real thunder]

aside of that chunks are used for many other things but I only curious about it

I am asking if anything in world record mob farms related to chunks being meshes

[sour fulcrum]

at a certain level (eg. mc) it's not necessarily easy to separate the rendering discussion from the logic discussion

[sour fulcrum]

not in itself no

[real thunder]

if each chunk is a mesh, well... it explains why half the server were crashing on my base
I got so annoyed that some things were not working evenly ect inbetween chunks that made whole ass huge modpack base in one chunk from the bottom to the top

[sour fulcrum]

semi unrelated if you wanna read into more minecraft related stuff someone who works on Sodium (big minecraft optimisation mod) did their thesis on transparency related tech https://douira.dev/assets/document/douira-master-thesis.pdf

you know game is good when someone from Uni making an analysis

Guys i have a 2d platformer game. Can anyone explain me why when I use imput system to move the chatacter (cube) with arrows, the cube trembles against a wall when I keep pressing the button? And i also made a checkground system to control the jump but why when my cube collides with the bottom/side of platform it can still jump? I want the cube to be able to jump when on top of platforms. Last thing, im not good at creating sprites so I ask chatgbt to do this, but I would like to use the tiled function on sprites (basically when you scroll with ur mouse or change the sprite size it repeat infinitely) but chat gbt sprites does not support this. What sprites i should use in order to use tiled function?

[slender nymph]

that first part sounds entirely unrelated to the input system and sounds more like you're moving it via the transform but it has a rigidbody that is causing it to depenetrate each physics update

[open crater]

How to fix that

[slender nymph]

move using the rigidbody. of course that is simply a guess since you didn't provide any actual details

[open crater]

Hm ok i'll do that

[pliant bridge]

what is it, I just new about using noise , and then zoomed in to make a chunk in that noise
I used perlin-noise to make it btw. And then it will generate the terrain with the noise

mesh generation

[open crater]

What about the other two issues?

[pliant bridge]

i'm searching it up rn

thanks alot

[slender nymph]

how can anyone provide any answers to any of that without any actual details

[open crater]

For the other two things i dont think i need to be more precise

[slender nymph]

you need to provide details about your current implementation that isn't working

but i'm not going to attempt to help you now since you don't want to do that so maybe someone else will come along and help with that 🤷‍♂️

[polar acorn]

The solution to one of them is "actually put effort into something instead of expecting the slop machine to provide useful output" so there's one

[errant breach]

Hello ! I have a small question
playerInAttackRange = Physics.CheckSphere(transform.position, attackRange, whatIsPlayer);

My game is a 3D game, i don't want the sphere to be on the enemy, but rather in front of the ennemy, so that if the player is behing the enemy, he's not detected.

• After looking on the documentation, there is not exemple on how to achieve that goal. I could add a value to the enemy's X position, but it would always make the sphere advance in the same direction...

If anyone know how to make it, i would be very thankful ! Thanks

[wintry quarry]

Make an empty child object of the enemy

Position it where you want

[slender nymph]

create a child gameobject that is positioned where you would like the check to be in relation to the parent, then use that object's position

[wintry quarry]

Use that object's position

[errant breach]

that's a really smart way to fix this issue, thanks ! ill make that :) !

[polar acorn]

There's also the option of adding transform.forward times some distance to the position, which will get you a position that distance away from the front of the object

[oak marlin]

how can I access a script and its public variables between different scenes

[polar acorn]

But, having a bespoke game object for positioning it lets you actually see the origin, so that's probably better

[slender nymph]

https://unity.huh.how/references/cross-scene-references

[errant breach]

Noted, ill check on that, thanks :) !

[pliant bridge]

ohhhhhh mesh generator

it was mentioned in minecraft wiki [https://minecraft.wiki/w/World_generation]

thanks alot @wintry quarry

[pliant bridge]

insane...

i got alot of information

insane

[orchid wolf]

Hey everyone, again. So I have this problem with sprite. Inside this black box I use "Grid Layout Group". When I add items in HUD manually it looks fine, but when it comes to play test, something wrong happens. Any ideas?

[frail hawk]

that happens because you did not use anchored positions for your ui elements

you probably just positioned them on your screen

[errant breach]

Hello, i am trying to use the SetParent

Here's the code :

var projectile = Instantiate(attackGameObjectParticle, BeakMuzzle.transform.position, BeakMuzzle.transform.rotation); projectile.transform.SetParent(BeakMuzzle);

The BeakMuzzle is a Transform well defined. But when the attackGameObjectParticle is called... It still has no parent !

Would someone be able to help me ? If you need the code, please let me know !

Have a great day :)

[swift crag]

hmm, you'd get an error if BeakMuzzle were somehow getting set to null

When I see no obvious problem, I will start checking my assumptions

such as "is this code even running?"

(it sounds unlikely, but what if you had two places that could shoot projectiles?)

I'd log the projectile's transform's parent before and after calling SetParent

[queen vale]

For setparent, you need to refer to the object's transform. BeakMuzzle.transform

[swift crag]

BeakMuzzle is a transform

(so, notably, BeakMuzzle.transform.position is redundant; BeakMuzzle.position is sufficient)

[naive pawn]

have you tried setting the parent in the Instantiate call directly

[queen vale]

transform.position != transform

[naive pawn]

(but yeah verify this code is actually being reached as fen said)

[naive pawn]

transform.transform == transform

[errant breach]

I see, i like your way of approaching issue and i will think of it next time, thank you ! :D
But @queen vale got the last word ahah thank you, it was the .transform issue, it's now fixed !

[queen vale]

Agreed, maybe im coming in late but they just mentioned
"(so, notably, BeakMuzzle.transform.position is redundant; BeakMuzzle.position is sufficient)"

[naive pawn]

i guarantee you it was not that, if it was you'd be getting a compiler error

[naive pawn]

they said that because it's true

[swift crag]

i don't understand what you'd have changed to fix your problem

[queen vale]

It's true but referring to setparent, it needs a transform not a position

[swift crag]

yes, and BeakMuzzle is a Transform, not a Vector3

[naive pawn]

you must not be reading something correctly here

you're arguing against a point nobody made

[swift crag]

I was referring to the prior Instantiate line here

[errant breach]

Oh really, oh, uh.. Weird..
Do you guys want extra information to be sure about that ?

[swift crag]

what did you change?

show us the new code

[naive pawn]

sure. as a sanity check, what's the type of BeakMuzzle

also another thing could just be that you changed the code and triggered a recompile when it hadn't before

[queen vale]

I don't mean to argue. I just want to answer the persons question regarding setparent

[errant breach]

public Transform BeakMuzzle;

var projectile = Instantiate(attackGameObjectParticle, BeakMuzzle.transform.position, BeakMuzzle.transform.rotation);
projectile.transform_SetParent(BeakMuzzle.transform);

[naive pawn]

yes, and you ended up trying to argue against a tangential point

[queen vale]

B ) and I was right

[naive pawn]

yeah all of the BeakMuzzle.transform here are all equivalent to BeakMuzzle

[swift crag]

it has exactly the same meaning, yes

[unborn basin]

hello I'm trying to get started with unity I already know c# I've already done winform ect someone has good tutorials or can even teach me a little

[naive pawn]

on what? that transforms and vectors aren't the same? noone was claiming that

[queen vale]

... yet i lacked context.. darn

[naive pawn]

!learn

[radiant void]

:teacher: Unity Learn ↗

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

[errant breach]

That's so weird because now it does work..

[swift crag]

if BeakMuzzle was a GameObject, SetParent(BeakMuzzle) would be a compile error

[unborn basin]

ty

[naive pawn]

probably this then #💻┃code-beginner message

[swift crag]

same guess here

you may not have saved your script

[naive pawn]

or it couldve been edited then tested in playmode by accident before

[swift crag]

unity can be set to not reload until you leave playmode, yeah

[errant breach]

Ah, maybe... That would be very unfortunate of my 😅

because i was in playmode

yes, i think unity just never took time to reload / i did not save. Sorry for your sanity guys 😅

[naive pawn]

iirc, unity kinda supports hot reloading in playmode but it's kinda wonky

i disabled that a long time ago

[swift crag]

it works if and only if all of your state is serializable

I don't try to use it

[naive pawn]

i guess that kinda makes sense

[sage mirage]

I did it at the beginning of the setup. I think it was AI that write it down by mistake XD

I don't have to use AI at all like even for any code help explanation or an example on how to fix something?

[naive pawn]

yes

[sage mirage]

I mean sometimes I stuck very hard on problems

I can't even think myself

[naive pawn]

imma be real i don't care

[sage mirage]

I have to get explanation from AI

[naive pawn]

so you let the AI think for you, and never actually learn to solve problems?

[polar acorn]

If you knew enough to be able to fact check the AI's hallucinations then you wouldn't need it.

[sage mirage]

jn order to actually get my brain to work

[naive pawn]

you aren't actually using your brain there 😂

learn to problem solve for yourself

you don't have enough problem solving skills to fix all the problems AI is giving you lmfao

[polar acorn]

It's a pointless tool because by the time you can actually make use of it without completely ruining your project you no longer need it.

[frosty hound]

People really out there thinking AI has always been the solution lol

[sage mirage]

Maybe you are rightI dont copy paste thats for sure I dont do it what I do is I see examples, explanations and also do all the research for the specific problem like tutorials, docs and other resources and then write the code.

[naive pawn]

ok, then keep doing that and leave the bs machine out of the equation

[sage mirage]

But I cant think how you seniors solve problems without the use of AI. Could you please help me understand? I know about divide and conquer or decomposition breaking problem into smaller parts but what if you stuck completely on a problem what are you doing to solve these problems? Maybe I need some more practice in algorithmic thinking like taking challenges on CodeWars or on any coding platform. I really want to improve problem solving skills.

[sour fulcrum]

research

[sage mirage]

Are you creating flowcharts

[queen vale]

slam your head into a wall till it works

[sage mirage]

class diagrams etc?

[sour fulcrum]

sometimes flowcharts are helpful yeah

[polar acorn]

Instead of reading hallucinated nonsense from the plagiarism machine, you can just... read the data it's stealing from

[sour fulcrum]

far from perfect but just an example of something i've made in the past incase it helps with inspo

just ways to visualise thoughts

[sage mirage]

Its called System Design or Technical Design right?

[naive pawn]

you know how once you get proficient with math, you can do additions and multiplications and stuff in your head without needing scratch paper?

that happens with problem solving too. you might see people just thinking for a bit and giving a solution, they can do that in their head because they've practiced a lot, enough to be able to do that. start with writing your thoughts out, see what gaps are there, research

[naive pawn]

drop the buzzwords

just start doing

[sage mirage]

I have made flowcharts and technical design diagrams

[naive pawn]

those formalized systems help make it more efficient or effective, but they're not going to help much without just the base experience of problem solving

[sage mirage]

the problem is you know I dont do the right think when it comes to decomposition

I think I am not taking the right steps in breaking the problem into smaller parts

[sour fulcrum]

most first time solutions are "wrong think" tbh

oh you meant right thing lol

[naive pawn]

that's normal

[sage mirage]

I am not doing it the professional way instead of typing immediately I think I have to write first the logic etc on a pseudocode and then actually apply after yeah writing all my thoguths

thoughts

[naive pawn]

go back and identify them, and see where you can improve

[naive pawn]

the professional way doesn't matter at this stage

[sage mirage]

Maybe I need more math knowlege?

Because I wasn't good in maths

in school to tell you

[naive pawn]

you need more practice

[sage mirage]

XD

[queen vale]

You only know what all you can do the more that you understand the tools that you have. Once you know what is available you can combine different things to find a solution.

[sour fulcrum]

is what your doing involving math?

[sage mirage]

Game Math is something relevant in our industry

[naive pawn]

you don't need more knowledge

[sage mirage]

I assume I need Linear Algebra, Boolean Algebra, Calculus, Discrete Math

[sour fulcrum]

if what your doing doesn't involve math, then not knowing math is not your problem

i barely know any math lmao

[naive pawn]

you need those to make stuff. you don't need those to do the actual problem solving

[sage mirage]

Math actually help you think as a programmer

if you are good in maths then I think it will boost you up

[naive pawn]

if you know 0% of those, but you can break down the actual problem into needing those, you will have smaller pieces that are easier to research

[sage mirage]

in problem solving anything

[naive pawn]

yes, that's with experience, not raw knowledge

just reading 50 wikipedia articles is not going to do anything

doing math problems is a form of practicing problem solving, just as doing phyics problems or what have you

[sage mirage]

One of my professors told me if you dont study maths in computer science you will be just good in programming not professionals.

[naive pawn]

and if you refuse to actually go do anything you won't be good at all

i've told you several times

you're in decision paralysis

go actually do stuff

discussing is not going to help

[sour fulcrum]

I hope your professors aren't as bad as you describe

[sage mirage]

I have some projects bro XD

I am working on projects wdym ?

[naive pawn]

you're currently debating how to learn problem solving

[queen vale]

rather than solving problems

[sage mirage]

How to practice Problem Solving and DSA the right way? That's the question.

Algorithmic thinking

[sour fulcrum]

by solving problems

[sage mirage]

Yes but what problems?

[sour fulcrum]

problems found in what your making

[sage mirage]

not random?

[queen vale]

What does your game need? What isn't working? why isn't it working?

[sour fulcrum]

work on a project and you'll find some

[naive pawn]

dude does not read

dude is treating this as a writeonly channel goddamn

[sage mirage]

I am not treating anything as a write only. I just want some guidance because I think I am confused. Are there any resources you could provide maybe?

[sour fulcrum]

you just gotta work on stuff

[naive pawn]

bro ive said so many things and you keep asking the same thing lmfao

[queen vale]

The tower of Hanoi

[naive pawn]

i would not recommend that tbh

[queen vale]

It's a problem. It needs solved

[naive pawn]

it's a very specific instance of "problem solving" with a specific solution

[sage mirage]

That will help me to improve problem solving XD

Its not even a coding issue

[naive pawn]

it's going to give practice for that one specific use

[queen vale]

It's an example moreso than practice. You've all already mentioned practice by doing

[eternal needle]

Youre asking a question so vague, the only answer you could get is vague. No one knows what problems you struggle with, nor what would be beneficial for you specifically.

[queen vale]

so I figured, give an example.

[naive pawn]

i don't think there are reasonable examples to give here ngl 🤔

[queen vale]

🤷‍♂️

[eternal needle]

There are many websites that have problems on them, like leetcode or whatever else is popular these days. If you want to learn common algorithms/graph theory/math problems you'll find all you want there.
You will rarely ever actually use these algorithms

[sage mirage]

I mean some people are really genius in programming and problem solving I mean I think they have a talent by the nature. I dont believe a lot in talent but it exists, and its actually genetics given by nature.

[naive pawn]

ive gone through that. it's 40% interest and 60% practice.

[sage mirage]

leetcode or neetcode maybe or codewars for example?

anything right doesn't matter ?

[naive pawn]

at this stage, most likely not

[polar acorn]

If you keep thinking you can't learn, then you never will

[naive pawn]

you don't have enough experience for it to matter

you just need to start

[sage mirage]

I am not a beginner.

[naive pawn]

i'm... aware.

[eternal needle]

I used a site thats basically local to my area. Just find something you can reliably use and learn from. I didnt like leetcode cause the paid stuff got intrusive at a certain point

[sage mirage]

I have coding experience and with Unity as well the problem is that I want to improve more my problem solving skills and DSA basically how to use Data Structures properly with Algorithms and actually improve.

[sour fulcrum]

you improve by "using data structures with algorithms"

[naive pawn]

"problem solving skills" and "DSA" are not that closely related

[queen vale]

I've been a hobbyist for a decade and still think of myself as a beginner lol.
You learn to solve problems by encountering a problem, and researching the solution.

[sage mirage]

But is it worth it because you waste your time and actually you dont build something valuable?

[naive pawn]

i think you need to focus way more on just the "problem solving skills" tbh

[sage mirage]

You don't build portfolio

[eternal needle]

Do you want to learn or not

[naive pawn]

is school a waste of time

is uni a waste of time

[sage mirage]

Yes.

[naive pawn]

is pregnancy a waste of time (for the child)

[queen vale]

yes

[eternal needle]

First you say your goal is to learn. Now youre asking about a portfolio. We're in a unity server too.
If you dont know what you want, go figure it out

[sour fulcrum]

give that fetus an ipad

[naive pawn]

maybe for you, since pregnancy is when the brain develops a lot

-# i intend that as a joke, just saw the opportunity...

[naive pawn]

you keep tacking on random shit that's completely irrevelant to the actual topic at hand here, which is practicing problem solving.
the specific problem you solve isn't going to matter that much at the stage of just decomposing issues

solve math problems if you want, 3b1b has a ton. the focus will not be on specific topics, but the actual problem solving

problem solving is an experience skill. all those others you're worried about, dsa, math topics, are knowledge skills

[queen vale]

i lack in the knowledge dept.

[naive pawn]

don't we all..

(hence the importance of research as an experience skill)

[sage mirage]

Iam aware that I have to practice my problem solving skills, but my point is to practice them by building portfolio instead of just taking random problems on leetcode or whatever platform there is because at the end of the day you will have to land a job maybe on an indie game dev studio or even on AAA studios when the time comes of course with the use of Design Patterns and all the solid principles which are really helpful.

[naive pawn]

you are worrying about distant, barely-existant problems

it's like you're trying to make an art portfolio and worrying about Official Color Theory™ with perfectly curved lines and professional techniques despite barely drawing. that's what it sounds like to me

ah to hell with this. it's not like you're going to actually read any of this

[sage mirage]

I read everything bro all the time, I don't know what you mean

When you see I ask the same question or maybe don't reply on any of your messages doesn't mean I dont read them. I just have my own concerns and keep repeating. Anyway, thanks for the advice I'll see what I can do.

[edgy tangle]

@sage mirage I know others have reiterated on this point but if your current problem is you don’t have a set of problems to solve in order to practice problem-solving with code as a skill, then just try to make something small yourself. Problems will arise. You will need to either solve them or give up. If you choose the former it’s how you practice and learn. But endlessly debating and talking about it won’t get you there

[woven thistle]

When I double click a script in Unity it automatically opens to the purple Visual Code Studio. However, I only have the blue Visual Code Studio set up for Unity coding. How do I get it so it automatically opens to the blue Visual Code Studio?

[naive pawn]

the purple one is called visual studio, the blue one is called visual studio code

you can change the selected external editor in project settings or preferences, one of the two. i forget

[queen vale]

(preferences > external tools)

[woven thistle]

[fallen forge]

Hey everyone, I am currently trying to set up a basic enemy AI that has two modes:

Wander (goes around the map randomly trying to find the player)
Chase (chases the player while they are in sight, if losing sight it does smart checking to figure out player location).

Does anyone have any good resources I can start with or advice where to learn mroe?

[grand snow]

Id go about it by having it have two modes:

• try to find player in some radius and check line of sight. If hit go to:
• follow player and try to attack them. If player leaves some radius, go back to searching.

[fallen forge]

For the player chasing, are there any built in algorithms such as A*? Will the AI by default detect objects in the way?

Thank you for the recommendation by the way

[grand snow]

AI is vague and means many things

Unity offers the nav mesh system which can be used to route to some goal with ease

Learn more with this course: https://learn.unity.com/course/unity-for-artists-curricular-framework-resources/tutorial/unity-navmesh

[solar hill]

A* (THE ASSET) is really good but the free version is kinda pointless imo

so stick with what unity gives you for now

[grand snow]

lets not suggest that to start

That is more applicable for non beginners

[solar hill]

what?

im telling them to use unity's default navmesh

[grand snow]

(also A* is an algorithm anyone can re implement for free)

[fallen forge]

I do have a lot of programming experience, it is just my experience with Unity development that is lacking

[solar hill]

im aware, i was refering to the popular third party asset that integrates it

[grand snow]

Ah then disregard that. If you are aware of A* or other similar DFS/BFS algos then you can also implement these but thats extra effort but may fit your use case better.

[grand snow]

I know ive heard of it but A* is not that

[fallen forge]

Yes, the coding is not the issue, I am just looking for Unity methods. I will look into NavMesh more.

Thank you both!

[spring root]

https://youtu.be/l8ADGZTwhmk?si=Y4NTMzjkZT893YGi
fairly comprehensive tutorial using navmesh

[timber tide]

a* project has 2D pathfinding tho unlike unity's

pretty sure that's included in the FREE version

[grand snow]

there are packages that make navmesh work in 2d too but yea its a dumb limitation

[timber tide]

also includes more baking options besides a poly-navmesh such as a grid mesh

which is better for games like tower defenses since easier to add restrictions to the indicies that occupy square units

[grand snow]

Thats cool but ive always done A* myself for node based systems

[queen vale]

I'd say something.. but idk the A* algorithm, aside from it finding the shortest path

[timber tide]

Yeah nodes are fine, and you can get a lot of precision at the cost of more mem, but still a little screwy when you do want to create precise zones to prevent walking.

[grand snow]

Oh yea they only work well in some situations

[woven thistle]

how do you make it so that the camera follows the character as he moves around on the map?

[queen vale]

multiple ways, most tutorials use cinemachine (for 3D)

Depends on 2D / 3D but brackeys got some tutorials on it.

[orchid wolf]

can anyone look at it?

[queen vale]

Can you expand on "when it comes to play test"?
Why is there a second knife?

[orchid wolf]

First one is to show how it's intended. They share same parent.
By playtest I mean picking up item in the game.

Grid Layout Group supposed to make them all same size

but for some reason it does something to sprite

That's what concerns me

Oh wait, I found the problem, for some reason it changes "InventorySlot" scale to 1.666

I guess, that's because my "Stack" is outside it's parent's bounds and when I create a new copy of this prefab, Unity tries to fit in all item by scaling up parent. But my number is anchored to the right corner so that does not help

testing it rn

[orchid wolf]

nope, it's position doesn't matter

Then, I have no idea

It's easy to fix, and I already did that, but just wonder what's nature of it.

[queen vale]

The prefab is the inventorySlot, and the slot is what's being scaled by the grid (iirc)

[orchid wolf]

but grid does not change scale

[queen vale]

grid doesn't no, but it shouldn't care about the slots children, just the scale of the inventorySlot itself

[orchid wolf]

yeah

Anyway, I don't really wanna figure out what's the problem rn, gotta get some rest

ty anyway

[queen vale]

Sorry : / , sleep well

[errant breach]

Hello guys

Im sorry if its not the right channel but it's kind of an emergency

I was testing my game and all of the sudden, it broke. It can happen but here, it's like if everything rollbacked to like 8 hours ago

i lost a lot of progression, some bugs that i fixed came back, some part of my model that i deleted / added got reverted to this morning...
It's like if i opened an auto save... Without really wanting it.

I just pressed "F9" while playtesting my game to record, and went into override > apply all before starting the game because i never did it with my playerCharacter

everything just... Vanished...

Like if i restored the player's prefab from 8 hours ago

Script got removed, everything is glitchy, the error "Unnassigned reference" is spammed...

[polar acorn]

This will take whatever fields you have set on the current instance and saves them to the prefab

Was the prefab the only thing that was changed? Because it seems either you overwrote something or just never saved it in the first place. Unity doesn't do auto-saves.

[errant breach]

I think that i've made a lot of changes to the player without applying them to the prefab and when i finally did.. It, like... Broke everything

[slow blaze]

Hey
I'm trying to implement a simple dialogue screen with a png as the char,
Currently I'm just using a canvas and an array of objects that has 1: the png, 2: the text
is there a more suitable way to do this?

[rich adder]

depends how complex you want to get...
also there are more out-the-box solutions that might do already everything to add manually. One good one is Ink(free), or yarnspinner (paid)

[errant breach]

So it also broke my AI's that were perfectly fine and always saved...

It reverted their particles and sound to null like hours ago

words cannot describe my confusion

And now, m afraid it will happen again

[slender nymph]

did you perhaps check out a previous commit in the version control you are surely using?
or are you perhaps storing your project in some cloud sync path like one drive?

[errant breach]

Well, i actually used to use VersionControl, but i no longer do it since yesterday, i deleted it..
And i dont, i installed an autosaver now but im so sad

[slow blaze]

what has encouraged you to not only stop using version control but delete your previous commits lmao

[slender nymph]

i no longer do
congrats, you've just learned a valuable lesson on why you should always use version control

[errant breach]

The infamous infinite domain (busy for 8:12) glitch

[slender nymph]

that's not related to using version control . . .

[errant breach]

I think it is, a saw it on forum and when i removed version control it finally removed this bug !

[sour fulcrum]

everyone should be using version control

[polar acorn]

And not necessarily UVCS

[slender nymph]

always use version control. whether it's git or unity version control, or some other actual version control software, you should always use version control
or else you end up with situations similar to this where something has broken irreversably in your project and you cannot revert back

[polar acorn]

But some sort of version control

[swift crag]

if nothing else, just use a local Git repository to checkpoint your work

[errant breach]

I trust you guys on the importance of using version control.. The only reason i removed it was because it almost added 8 minutes of booting everytime i started a playtest...
I added this plugin : https://assetstore.unity.com/packages/package/43605
If you guys have any suggestion of great plugins / version control i can use without this glitch, i would gladly take it :')...

This is my Unity version, btw..

[sour fulcrum]

github desktop

[swift crag]

i have no idea how having Unity Version Control present would slow down entering play mode that much

[polar acorn]

Personally I would just remember to save, rather than getting an asset for it.

I save so often I'll Ctrl+S periodically on discord

[swift crag]

note that remembering to save and using version control are two completely unrelated things

pressing ctrl+S regularly doesn't stop you from deleting something important

[errant breach]

I have no idea too, got UVC during one month, got that glitch for one month. Removed UVC, got the glitch removed

But i mean... Ill try to add UVC back then !

I just uuh i-

oh alr

[solar hill]

You could also just use git instead

As a suggestion, a lot of people prefer it over uvc

And issues like this dont really happen

[errant breach]

Alright, i will configure git with a tutorial then, thank you very much !

[errant breach]

Well i also putted UVC and i already have the glitch

It sometime take 8 minutes just to compile when there's UVC, definitly a weird glitch. But i did put Git

I think i understood what happened

i put "ctrl" in my game to run and i think i did things like "ctrl + s" or "ctrl + z" while in game and it broke something

I just got the exact same error after playtesting : got hit by a rollbacl

[muted sand]

How would I implement currency into my game? Would I just have one big script to handle it all? And how do I know what is on the client or the server?

[rich adder]

implement currency
this is vague as hell

[teal viper]

Generally, you probably don't want to handle the logic on the client at all. It shouldn't do anything beyond displaying the data from the server and making usage requests to the server.
And honestly, if you're struggling with such questions, perhaps it's to early to do multiplayer..?

[muted sand]

I meant what logic runs on the client vs server
e.g. If I put a script that does x, would it be running internally on client or server?

I haven't implemented multiplayer at all but I'm assuming you store each player's stats in a table

[teal viper]

It depends on what networking framework you use and how you implement the script. Normally everything runs in any build - both the client and the server. You should probably go over these before even starting to plan your multiplayer game.

[pliant bridge]

I wonder about multi level world generation, is it based on how many tilemap layers(with different Z level & sorting order) you have?
I made multi layer noise with perlin noise, heightmap texture, perlin worm, spline shaping, using mesh world generator method (similar minecraft).

But the world generation seems cooked, no multi level like 2nd, 3nd picture

[muted sand]

I don't have any network framework

[teal viper]

Well, then there's not gonna be any multiplayer. No need to worry about that part then.

[muted sand]

How would I implement it?

[rich adder]

perhaps it's to early to do multiplayer..?
💯

[teal viper]

Do you really expect a reasonable answer to that question? It's basically the same as asking "how do I make a game".

[polar acorn]

Implement what

[teal viper]

The obvious answer is "you learn it, plan your game with multiplayer in mind, select the right framework, integrate it based on what you learned, docs and tutorials".

[muted sand]

What's a framework to start off with?

[teal viper]

Probably the solution that unity provides - net code.

But again, I think this is too early for you.
Even this question kinda reveals it. You need to start looking up/researching stuff on your own. You could easily Google for what frameworks there are, read about their pros and cons, but you didn't do it and just chose the lazy way. That means you're not ready for networking as a developer yet.

[muted sand]

I'm asking a reasonable question in a discord server about the literal engine itself
How am I supposed to know without any experience?
You can't expect every developer to know what to ask like they are Linus

[teal viper]

You're expected to be able to do minimum Google search. You were already provided with the right keywords many times over.

[muted sand]

I'd expect a half helpful answer in a server about it

[ivory bobcat]

Most of this can be Googled as suggested.

[teal viper]

We're not here to spoonfeed you or provide you a ready solution. We're here to help you grow as a dev. If you expect someone to do everything for you, perhaps this is the wrong server.

Neither are we a replacement for Google.

[teal viper]

And also, no. Networking is not "about the engine itself" it's a general gamedev(or even software engineering) concept. And a pretty advanced concept too. Unity does provides tools to implement it in your project(which I already mentioned), but there are many other solutions. And regardless of the tools you use you need to learn the general concepts first.

[muted sand]

I was asking what the scripts run on behind the scenes

[teal viper]

And I answered it, didn't I? They run on the machine that runs the executable.

There's no separation between a client and server by default, unless you explicitly implement it.

[muted sand]

That's assuming I don't run multiplayer

[teal viper]

Indeed.

But you don't. Because there's no simple "turn multiplayer on" button.

[muted sand]

There's no custom script type you use for this? Or do you need to use a networking framework for that?

[teal viper]

There's no script for that by default outside of what the dedicated frameworks provide.

[muted sand]

Ok

[woven thistle]

for some reason when I add an image to a sprite renderer only part of the image appears, what causes this. also the image is not fully connected, although all the components save as one. Could this cause it for only one individual component to appear on screen?

[marble hemlock]

collider.bounds.center
is there like a way i could have another version that goes for the top of the collider?

my options really only seem to be like max, min, center, and thats about it

[eternal needle]

get the y value of the extents then add that to your center

[pliant bridge]

Do you guys have any ideas that use mesh generator, perlin noise, perlin worm, and heightmap texture to make world generator in isometric 2.5d ?

i was only use perlin noise to make world generation but it was... flat

yesterday i knew about mesh generator and about minecraft world generator was using it with multi noise layer

to make world generator

so i try to make it

but now it only generate mesh terrain instead of tiles

[teal viper]

There are various procedural mesh generation algorithms. Some generate smooth geometry, some voxel based, some cube based, etc...

[pliant bridge]

god...

i am so cooked

[pliant bridge]

i wish i have a ram in my head so i can store those shit maths to develop a game

[marble hemlock]

thank ye
never used collider.bounds before so it was a lot of experimenting and failing\

[orchid wolf]

Is it possible to display something like that in inspector?

[undone rampart]

Yeah, just make it serializable

[orchid wolf]

Stats1?

ok, let me just ask straight, how?

Tested, that worked

thanks

[sage mirage]

You better use System.Serializable to be sure that you are using the namespace.

[naive pawn]

the monobehavior there doesn't need to be marked serializable for this btw (unless you need it for something else)

[sage mirage]

Hey, guys! What is the best way to actually assign game objects and componets etc at runtime? Is there a Design Pattern that is really useful in this case? Let's say we have two scenes title and main and you have to do dont destroy on load and then at runtime assign game objects or components? Personnaly, what I do is to create bridges between the Manager class that lives on the first scene loaded and bridge this class with a class that lives on my other scene and attaching the components or game objects at runtime like this
For example

I was wondering if there is more efficient and probably reliable way to handle assignments at runtime when persistence is needed thats the question. Thanks!

[undone rampart]

I would just avoid persistence between scenes completely

what do you need persistence for?

[sage mirage]

So, if you were in my place you would just use duplicate Managers in all scenes you have?

[undone rampart]

thats actually exactly what I do

[sage mirage]

That's not efficient at all personnaly thats horrible

No you dont have to

Having two game maangers, two ui managers

two audio managers

[distant orchid]

Hey guys any YouTuber who makes good tutorials for beginners? For c#

[sage mirage]

thats duplication it break single responsibility principle

[undone rampart]

I have a prefab called game manager and on that I put the main game manager and other submanagers, that prefab is present in every main gameplay scene. And to avoid repetition I use scene templates.

[timber tide]

Why would you need a secondary audio manager

[sage mirage]

You create an Audio Manager, Game Manager and UI Manager and you are persisting them across scenes thats the efficient way I think

[timber tide]

just make a script that works for all cases. Shouldnt be too many

[undone rampart]

Who said anything about two?

You just have one per scene

During that scene lifetime

[sage mirage]

Bro when you change scene everything in the previous scene get destroyed

[timber tide]

DDOL

[sage mirage]

DDOl?

Yes thats what I am saying

[timber tide]

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[sage mirage]

The other guy says he is going to create more than one of the same managers

Managers should be 1 and only one in the game

[undone rampart]

You missunderstood me

I said I duplicate them in every scene, like copy from one scene, paste in another

not that I have multiple in a single scene

well, I don't actually have to manually duplicate anything since I use templates and prefabs

[timber tide]

I assume the problem is switching scene and some variables become unassigned, destroyed with previous scene, and now you're assigning newer values that are scene dependent

which in that case you choose not to use DDOL, and just recreate that manager in each scene, but the static accessor stays the same, or just search the scene for the require components (or via another manager), or have those scene dependent options assign themselves to the manager via static call.

like you can recreate the singleton in each scene which is fine. This allows you to go on the editor and do direct assignment

audiomanager though may not be ideal as you do usually want some cross-fade music, and similar type of managers that do fade between

[sage mirage]

Yes thats what I mean you are copying them thats also bad practice

Managers must be its a "MUST" only 1 of the same type in the game.

[naive pawn]

singletons can destroy duplicates

that's the entire point of that Destroy in the singleton pattern

[sage mirage]

Thats what I am telling him DDOL

is the solution in this case

[naive pawn]

you don't really need that tbh

it is a solution

[sage mirage]

you mean DDDOL?

[naive pawn]

it's not the only solution

[sage mirage]

yes but my question was and how this conversation started

[undone rampart]

yeah, thats still the case

[sage mirage]

the question was

@undone rampart said I copy managers across scenes

[sour fulcrum]

(Most people probably wouldn’t recommend this)

[sage mirage]

Bro that's super inefficient and doesn't cover my question

There is a thing OnSceneLoaded

So whenever you change a scene you can also assigne references at runtime

I did it with scripts called bridges

[naive pawn]

why does the UI manager have specific types for every scene

seems unnecessary

[undone rampart]

My final point was if you don't use DDOL, then the managers get destroyed and initialized within the scene's lifetime, that way you don't have to worry about cross scene initialization and references breaking

[undone rampart]

I feel like yall are ignoring most of the things I am saying

[sage mirage]

You mean MainSceneUIRefs and TitleSceneUIRefs?

[naive pawn]

yes

[sage mirage]

I mean I was thinking of another more efficient way

there is OnSceneLoaded

[naive pawn]

it's structured like you're trying to use this as an abstraction, but you still have that tight coupling there

[sage mirage]

but i was wondering maygbe there is a design pattern that is really useful

or anything

a structural design pattern

I think

[naive pawn]

stop worrying about design patterns tbh

they'll pop up if they're useful

not everything needs a fancy name

[sage mirage]

That's just a way to communicate with programmers

Design Patterns are common solutions to many software design problems and thats why I am asking if there is anything to this one I am dealing with which in fact is a structural issue.

[undone rampart]

You can try the Core Manager Hierarchy I came up with that I mentioned in this thread #1488843522747531326

This graph shows the structure of it

[strong wren]

Starting with every scene containing everything they need to run as a baseline to then add complexity to if needed is not the worst thing you can do.

[sage mirage]

I dont think thats a good architecture diagram. Game manager doesn't have to manage other managers. Each manager is responsible to manage specific tasks and not only Game Manager should be a singleton I assume.

Player Manager is actually player controller or something?

its not a manager

[undone rampart]

The arrows point down not up

Why are you taking everything I say backwards 😂

The arrows represent a direct reference

The GameManager is the root

[swift crag]

it's perfectly fine for some systems to be repsonsible for others

[undone rampart]

Each node is responsible for its own logic

[sage mirage]

Audio Manager handles audio everything related to it, UI Manager handles the whole UI, Settings Manager handles settings of the game, Game Manager handles states like game over, ennd state. I mean the duplication thing you said with managers bro thats horrible and my quesdtion was about efficient ways to handle assignments at runtime and that wasn't really helpful, but anyway it is what it is.

[undone rampart]

Bro...I just said I am not duplicating anything in the scene

[fickle plume]

You don't want any rigid game design diagrams or patters in game dev. Each project requirements can be drastically different. You should only go by general philosophy to break down complicated pieces and responsibilities.
It's mostly trying things and refactoring, actual structure can drastically change depending on changing features etc.

[sage mirage]

Yes it is but not when it comes to managers I think because a manager is on its own responsible for himself and for other classes maybe there are dependencies on managers as well like you can think lets say a Controller Manager that handles Player Controller and AI Controller maybe yes.

[timber tide]

efficient ways to handle assignment is just do it on the editor if you can

[swift crag]

all of the design patterns in the world won't do much if you do not actually make a game

to quote Joel On Software from back in 2001...

When you go too far up, abstraction-wise, you run out of oxygen. Sometimes smart thinkers just don’t know when to stop, and they create these absurd, all-encompassing, high-level pictures of the universe that are all good and fine, but don’t actually mean anything at all.

[fickle plume]

And it's much more important to know with what purpose certain design pattern was created to solve what problem, than to know how to rigidly implement it. Because you often need some elements of it and not others.

[swift crag]

in my own game, I have a structure like this:

• GameController is the god-object. It is a singleton. It bootstraps itself on game start and is responsible for switching modes (e.g. from the main menu into a gameplay scene).
• Each scene contains a bunch of *Manager components. These are singletons as well, as you can only be in one gameplay scene at a time. They are thrown out when you switch scenes, since none of their state is allowed to survive from scene to scene.

[timber tide]

1# ControllerManager is created each scene and PlayerController is referenced directly referenced from the editor in each scene
2# SceneManager (unique per scene) has reference to PlayerController and assigns it to ControllerManager on Awake, or through GameManager entry point call.
3# PlayerController on Awake assigns itself such that ControllerManager.Instance.SetPlayer(this)

[swift crag]

You should implement code that does what your game needs.

I didn't create VisionManager because of some kind of design philosophy or grand plan. I made it because I needed a way to gather a bunch of visibility checks together so I could run a single giant RaycastCommand and return the results on the next frame.

er, well, that's not quite right; that's VisionSystem 😉

[timber tide]

I like doing GameManager entry point assignment where on sceneload the GameManager fetches all static scene accessors and does assignment.

[sage mirage]

I don't know how some people don't have an idea of Design patterns they actually write implementation of a pattern but they dont even know what is this implementation XD

[undone rampart]

I do this ^^^

It's very common to have multiple managers in a scene, so this tree makes it easy to reference those managers without having to manage and remember multiple singletons.

[sage mirage]

I have a friend that is a programmer I told him about Design Patterns and he said what are these stuff that are you talking about

[undone rampart]

It happened to me, I learned events and started figuring out that I can decouple a lot of stuff by using them, so I did the observer pattern without even knowing about it

[swift crag]

i don't think about "design patterns" consciously, but I certainly design my software

I don't think "time to use the observer pattern!"

[timber tide]

I think in terms of what will not cause race conditions

and most proof concept is just have a manager entry point

[verbal dome]

A lot of us use "design patterns" without even knowing they exist

[sage mirage]

There are in total 23 Design Patterns all of them categorized in 3 types Creational, Structural and Behavioral of course with their pros and cons as well and they are used in different scenarios. PErsoannaly, I do think about design patterns I want to implement because I dont know a lot for now only State, Observer, Singleton and object pooling

[undone rampart]

I think we need a special "architecture & design patterns" thread

[sage mirage]

That would be cool if there was a channel specifically for game architecture and design patterns and these stuff.

[undone rampart]

I think you can just create a thread in #1390346827005431951

[timber tide]

24/7 chat of debating what dependency injection really means

[swift crag]

it sounds like you just read a blog post about design patterns and now think everything is a nail that this hammer needs to be used on 😉

there are absolutely not a specific number of "design patterns"

[swift crag]

DI is when you get things

float Add(float a, float b) => a + b;

            JumpHeld = _jumpInput.IsPressed(),
            Move = _moveInput.ReadValue<float>() * Vector2.right
        };

        if (_stats.SnapInput)
        {
            _frameInput.Move.x = Mathf.Abs(_frameInput.Move.x) < _stats.HorizontalDeadZoneThreshold ? 0 : Mathf.Sign(_frameInput.Move.x);
            _frameInput.Move.y = Mathf.Abs(_frameInput.Move.y) < _stats.VerticalDeadZoneThreshold ? 0 : Mathf.Sign(_frameInput.Move.y);

[night raptor]

If you get an error when creating the frame input it means something inside the object initalizer is null

so either jumpInput or moveInput is null

[swift crag]

(pedantry time: that's the object initializer, not the constructor!)

but yep, that's spot on

importantly, this kind of thing would not cause an error

var foo = new Bar() {
  thingy = thisIsNull
};

(assuming thingy is a simple field, of course)

the mere presence of null is fine; trying to access a member of null is what causes problems

[elfin pike]

1 frame before my character spawn something in object is null?

[polar acorn]

Whenever that line of code is executed, either _jumpInput or _moveInput is null

[small gyro]

Quick question is this the "proper" order of things:

// 1. Enums / Nested types
// 2. Constants / Static fields
// 3. Serialized fields ([SerializeField])
// 4. Private fields
// 5. Properties
// 6. Events / Delegates
// 7. Unity lifecycle (Awake → OnEnable → Start → Update → FixedUpdate → LateUpdate → OnDisable → OnDestroy)
// 8. Public methods
// 9. Event callbacks (OnCollision, OnTrigger, UI handlers, etc.)
// 10. Private / Helper methods```

[polar acorn]

Order for what

[naive pawn]

no, because there is no "proper" order

as with all things related to code style, if you're consistent with it then it's fine

[small gyro]

Oh awesome. Thanks!

I noticed that when I am more consistent with how I order stuff, it makes it easier to learn and debug.

So, if there was a recommended one or something I'd just follow that. But seems like I am fine with what I have 🙂

[naive pawn]

there are several recommended* ones as set by like, companies for internal consistency, and you could use those

-# * recommended as in, within the company. outside it's just a set that definitely works that you could use so you don't have to figure it out yourself

[timber tide]

lot of languages usually want some type of method declaration at the top however

c# dont care tho

[swift crag]

I do sometimes interleave fields and methods, but only really for "debug" stuff

so that it stays out of the way of the normal fields

[naive pawn]

a lot? i know of only c and c++ that would do that, though i'm not very familiar with lower level languages

wait no, c/c++ also don't care in a class

[swift crag]

this only matters in languages that require you to declare a symbol before you use it

e.g. HLSL or C

[timber tide]

well, header files help prevent the compiler complain about those issues

[naive pawn]

hmm i kinda have conflicting thoughts on this comparison

[timber tide]

but yeah, 'most' languages could be reduced to mostly lower level languages today

[naive pawn]

this is within a class, and afaik, no language has this kind of requirement for classes? only some for free functions in eg c, c++, python
and the free functions one i feel is a different situation

i guess c# does indeed also not care for local functions, but i feel like that's not relevant to the specific topic at hand

[edgy tangle]

The general pattern I see and use most often is loosely:

1. private/protected fields (serialized or not)
2. public fields (if any) and properties
3. Events/delegates
4. Common Unity lifecycle/event methods/ “callbacks” (Awake, Start, OnEnable, OnDisable, Update, OnTriggerEnter, etc.)
5. Class-specific methods, loosely in descending order by how common or core they are to the script.
6. Less-common/core methods and helper/utility methods.

But this isn’t some “correct” order. Just what has seemed to work for me and most of the people I work with.

But most important is just to try to follow some general format across your scripts so you don’t need to recalibrate your thinking every time you look at a different script.

I forgot to put const/statics in the list there, but usually those will go near the top as well. Don’t have any hard rule there though.

[naive pawn]

eh while we're sharing, i had this mess for one of my projects lmao

[polar acorn]

My code order:

Wherever it goes, it goes

(You shouldn't be writing code so long you need a style like this, IMO)

[naive pawn]

you do have a style, maybe you just haven't written it down :P

[swift crag]

that's the punchline

if you start having to think really hard about order, something has gone wrong!

not that I'd ever write a monstrous 1000 line long class

no sir-ee

[naive pawn]

oh i didn't have to think of it for myself, but i realized it was kinda convoluted so i formalized it for someone else who was offering help

[edgy tangle]

Still having some sort of consistency is helpful even for short scripts. It’s really irritating to find a critical field randomly among method definitions even in a script that’s <100 lines.

Like Fen mentioned earlier it’s fine if that field is just used for debugging or something so you don’t really want to pollute the “header” area of the script with it, but if it’s a field that’s critical to the class it’s annoying to find that whoever made it just placed its declaration in some random line in the body of everything else.

[swift crag]

I do try to put all the fields at the top

roughly grouped by meaning

(since that order affects what you see in the inspector!)

[sour fulcrum]

thats a new one

Idk why but when I reload the scene its not initialized properly. I tried debugging for persistent objects but nothing came up

[slender nymph]

save the scene before entering play mode. when you load it via code again it loads whatever was actually saved to disk

[earnest raven]

I'm guessing I can ask this here. (I hope)
I have a Stack Camera, but I haven't prepared for it in-code. I have a Dynamic FOV thing and the stack camera doesn't inherit the FOV of the Main Camera -- Can I make it so the stack camera inherits the FOV automatically or do I need extra code?

[opaque shell]

huh?

[slender nymph]

what about that is not clear? your scene is not saved, you need to save it

[opaque shell]

I do save it, like hitting file and save I do that

[slender nymph]

it was clearly not saved in the video you showed

[naive pawn]

having an asterisk or a dot beside a filename is an indicator that it's unsaved

make sure that asterisk disappears when you try to save

if it doesn't disappear, you didn't save

[opaque shell]

oh I see, sorry. The issue still persist tho

[slender nymph]

you should describe exactly what the issue is, because if you've saved then it is loading the scene as it was set up. so if something is going wrong then something else is the issue

restart the editor, just looks like an editor bug

[swift crag]

yeah -- if you see "UnityEditor" in the error, it's probably not your code

and most of these UI bugs are fixed by either:

• restarting the editor
• resetting your layout to one of the presets (there's a dropdown in the top right)

the latter will help if there's a window that has somehow wound up with invalid data stored in it

[dry tundra]

Thanks you
I fixed the problem by updating the unity version Control in the package manger

hello everyone. I've got a little problem. I have this app imp building in unity where I generate some trinkets and they're supposed to fall on a littl platform. works perfectly fine locally, but they fall through that floor on a web build on Play. is there a common issue I need to be aware of when deploying to Play?

[wintry quarry]

You migjht have framerate dependent code, or you might not be moving your objects properly via the physics engine, or you might not be using the appropriate collision detection mode.

[vapid egret]

Okay. I'll look into those possibilities

[orchid wolf]

ik, was testing usage of this tag

[wintry quarry]

if you share your code and how your objects are set up here, we could potentially help you identify such issues

Hi guys.

[pliant bridge]

Im currently remaking my isometric world generation so i have a question, so when i make multi level terrain, i set base tilemap layer height is 10 (in the image) , and make a world generation, it will generate a flat world

but when i use perlin-noise to make world generation , it will generate to this image
so the question:

Do i need to make a function that auto generate multiple tilemap layers to make it like 3d terrain? or just use 1 tilemap , and then change the height of the tiles

this stuck in my head for days

[frosty hound]

Changing the height of the tiles seems like the obvious solution to me. 100 layers = 100 tilemaps is crazy, not to mention having to then communicate between them if you're moving along the surface of the terrain.

[swift crag]

The only headache I can foresee is that it'll be hard to actually figure out which tile you're clicking on

You can't just map a screen position to a grid cell anymore

since the cell you hit depends on the height of the tile

this also means that you can't change elevation by more than 1 unit at a time

[pliant bridge]

"100 layers = 100 tilemaps" , yea i was thinking about this , that why i have to remake my world generation.
i was thinking about change the height of the tile solution too, but thinking about the logic is easy but do it in 3d isometric is

kinda tough 🙁

thank you two for giving some solutions

[bitter pine]

is there a way to make an animator have an event from a script that isnt on the same as the animator component?

[bitter pine]

im trying to crunch down memory usage as much as possible and i cant have mutliple of the same script on different objects, its inneficent

[frosty hound]

No, animation events have to call a function on the object that animation is playing. Having a small component that just fields the event functions is fine?

[bitter pine]

mk, if i have to then ig i have too

[swift crag]

Why do you think you need to do this?

[bitter pine]

im using an OLD version of unity 5.6.6f2, because im using unityfor3ds to well, make games for the 3ds. and the 3ds is very limited with memory. so im trying to limit the amount of scripts i use a scene

[naive pawn]

seems like the memory of the animator itself would overshadow anything like that

[bitter pine]

hm probably, i should also look into that

[naive pawn]

do some profiling, see where the memory loads actually are, rather than going after small details

an animation component would probably use less memory given that it doesn't have to keep track of layers/states/transitions/parameters 🤔

though also the assets themselves would likely be significant memory

you pointed me in the proper direction. it was the framerate. Now I need to try to get this thing to work in unity play on phones.

Here comes a new question! I'd like to send a family friend a little project on Unity Play. It currently works just fine on desktop browsers, but I have to switch to desktop mode on the phone because Unity play says the game is not supported on mobile. Are there build settings that I can change to get it to work in chrome/safari mobile?

[wintry quarry]

[lethal grove]

question, I tried 2 layers on an animator but they aren't let's say "fusing", both layers each have their own mask, one is upper body and lower body. The animations on each layer only handle the parts of the body they should be managing.

I tried watching tutorials but they always use imported animations, I'm using .anims in my case so I can't convert my anim into a humanoid as they do in the tutorials

I'm kinda lost

[slender nymph]

[glass summit]

I'm making a Parkour game in Unity, and I want to make a simple Jump feature where the character jumps when the player presses the spacebar. The Jump button won't work normally, because when I click the spacebar, the ParkourController is looking for an obstacle in front of the player so I wanna make it so that the Player should jump when click the spacebar, but if they are facing an obstacle, they perform a Parkour Action like usual

[Header("Jump Settings")]
[SerializeField] float jumpHeight = 2f;
[SerializeField] float gravityMultiplier = 2f;

bool jumpRequested;


if (!hasControl)
    return;

// Jump input
if (Input.GetButtonDown("Jump"))
{
    jumpRequested = true;
}
if (isGrounded)
{
    ySpeed = -0.5f;

    if (jumpRequested)
    {
        ySpeed = Mathf.Sqrt(jumpHeight * -2f * Physics.gravity.y);
        jumpRequested = false;
    }
}
else
{
    ySpeed += Physics.gravity.y * gravityMultiplier * Time.deltaTime;
}


public void CancelJump()
{
    jumpRequested = false;
    ySpeed = 0f;
}```


``` ParkourController.cs

private void Update()
{
    if (Input.GetButtonDown("Jump") && !inAction)
    {
        var hitData = environmentScanner.ObstacleCheck();
        if (hitData.forwardHitFound)
        {
            foreach (var action in parkourActions)
            {
                if (action.CheckIfPossible(hitData, transform))
                {
                    playerController.CancelJump(); // stop jump

                    StartCoroutine(DoParkourAction(action));
                    return;
                }
            }
        }
    }
}```

[meager gust]

I don't know if you've given enough information on what this is doing or why its not doing what you're expecting

if parkour action is found... then cancel jump

where problem?

you might want to invoke ParkourController from inside your PlayerController.cs. Or at least the part that checks for the jump input

the way you have it right now: if the parkour controller is running first before playercontroller, its going to cancel a non existent jump

and then the jump gets created when the playercontroller runs after it

I dont have enough info but thats where I would start

[median hatch]

you can just have a raycast

check if there's any layer mask in front, if not then just jump normally

[orchid wolf]

Hello, am I doing something wrong or it's justi mpossible to serialize generic type?

[naive pawn]

you're expecting to serialize just original, or...?

[orchid wolf]

yeah

[naive pawn]

the serialization rules manual doesn't mention anything about generics, so i don't think there's anything special there

[naive pawn]

wait are you expecting those maxHealth etc props to be serialized

[orchid wolf]

Somewhat, I was thinking about unity displaying original

so I could easily change that

[naive pawn]

props aren't serialized

fields are

[orchid wolf]

original isn't prop...?

[naive pawn]

if you want an autoprop there, serialize the backing field, [field: SerializeField]

[orchid wolf]

or wait

Imy dumb ass

[naive pawn]

but maxHealth etc are

[orchid wolf]

ye

I didn't notice that

thanks

gotta check that I guess

but I already to implement different solution lol

[cosmic dagger]

you need to serialize the property with [field: SerializeField] . . .

[chilly barn]

im trying to have a minimap in the upper corner that will follow the ship, since most of this is text panels except the map you click to move your ship, but right now the minimap isn't loading but the ship is confined to the box, but the camera doesn't follow it so it just drags across the screen

[naive pawn]

wouldn't the minimap be UI, unrelated to the actual ship

[chilly barn]

wdym?

[orchid wolf]

that worked, in a wacky way, but worked

[naive pawn]

i mean what i said. i don't know anything about the context you're working in, other than what you gave, which is.. not much

[naive pawn]

well, that is how you structured it

if you want it to serialize just that 1 field, you would probably need something like a custom inspector/drawer/serializer.. not sure how those would work though

[orchid wolf]

Maybe there is way to play around with serialization to display this Original as Max Health. Maybe operator =?

[orchid wolf]

ye

[chilly barn]

So pretty much the goal is to have a map on the upper right that acts as your way to control your ship, so you press somewhere on it and your ship turns and moves there and the map follows. The rest of the screen has text panels and stuff. Right now the ship just moves around in its little confined square but there’s no map and the camera doesn’t follow it. I guess the final goal is for it to look like the ship isn’t moving because the camera follows it yk?

Does that make sense

[orchid wolf]

I mean, it's kinda fine

[naive pawn]

operators have nothing to do with this

unity introspects the structure, not the interfaces

[orchid wolf]

mk

[naive pawn]

and what is that map? a canvas, or what exactly?

or do you intend for that "minimap" to be a window into the gameworld

[chilly barn]

Right now I have it set up on a canvas as a UI element that you click to make the ship move

If you click anywhere on it the ship moves there

[chilly barn]

Maybe more similar to that

The actual movement and world map and everything is in that upper right window

The rest of the screen is UIs for text and information and terminals and stuff

[naive pawn]

how are you actually representing your world

it's starting to sound like it's not actually a minimap, but the only spot where it's not UI

[chilly barn]

Yeah more that tbh

I’m just not sure how to apply it

The whole screen is UIs and then the upper right is the actual “gameplay” for the most part

So I guess minimap is the wrong word

It’s just the map

But small and in the corner

[naive pawn]

i'm not sure what the ideal fix for this would be, but i have a few ideas

• static camera, ship doesn't move, world moves around the ship
• moving camera, moves along with ship
• static main camera, ship moves in some other place, there's another camera that follows it and that's used in the main ui

[orchid wolf]

A little bit of AI help and we have a good solution.

not sure if I need to override GetPropertyHeight, but I don't think it's crucial

[chilly barn]

I sort of like the ship moves somewhere else and there’s just a camera showing it I think that would work best

How would I set that up tho where I can click for the ship to move still?

[naive pawn]

the camera would follow the ship

[chilly barn]

I see..

your ide appears to not be configured properly

!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
• JetBrains Rider
• :question: Other/None

[naive pawn]

the issue is likely that your class isn't being picked up because there are compile errors. configuring your ide will highlight said compile errors for you

[sleek prairie]

this one doesnt work sorry mate but thank you thou

[sleek prairie]

should i install a different visual studio instead?

[naive pawn]

vscode can work fine

you just need to configure it

it seems like you were midway through configuring it but it's not done

[sleek prairie]

aight lemme try

[naive pawn]

if you've configured it fully, the using UnityEngine; should not be grayed out, and you should see some errors highlighted.

[sleek prairie]

aight, also is this correct?

[naive pawn]

looks about right

have you installed .net using that .net install tool?

[sleek prairie]

i just installed this, idk if this is the one you were talking about

[naive pawn]

it is not

i specifically said "using that .net install tool"

the one you installed in vscode

with this one you have to restart your pc or something. i don't remember, i haven't used this

if you install it with the extension, you just have to restart vscode

[sleek prairie]

oh i have

i havent restart my pc yet thou

lemme restart then

[naive pawn]

you've installed the extension. my question was have you used the extension to install .net

[sleek prairie]

oh you were right i havent

do i have to checkmark all of this?

[naive pawn]

those are settings

you do not have to change any of those

open the command palette (ctrl+shift+p) and search for install .net or something along those lines

[sleek prairie]

i got these

[spice burrow]

is it possible to change gravity scale in the script??

nvm figured it out

[night raptor]

The Scripting API page has all the available properties and functions for a given component https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Rigidbody2D.html. Usually everything that can be changed in the inspector can also be in script, the other way around may not be true as often

[naive pawn]

iirc the first, i don't recall seeing that 4th one

[sleek prairie]

it's okay mate i already solved it, thank you for the time thou

[torpid kettle]

does anyone know of a way to benchmark all thread groups of a compute shader? waiting for readback gives unusable results as it's impossible to tell how much time was spent on the compute shader, and how much was spent in reading the data from the buffer. any hint would be really appreciated, it's difficult to decide what optimizations to make without knowing for sure how code performs

[spice burrow]

https://paste.myst.rs/74ubmr3c

Anyone know how I could clamp the speed or like, set it to the max speed automatically after it reaches it?
This is for a simple missile.

[torpid kettle]

@spice burrow you can use the Lerp function, so you can kinda have a smooth clamping. or else you can use
Vector2.ClampMagnitude(vector, maxSpeed);

[spice burrow]

hmm alright

I'll take a look

[naive pawn]

yeah seems like you'd just clamp the velocity

Is there any Mouse.current.middleButton scrolling function? I want to check if the scroll wheel is being scrolled down or up to change between two settings/modes.

[swift crag]

there are bindings for the scroll wheel, yes

[summer bear]

If I want to implement short hopping for jumping (ie. if the player releases the jump button early), what typically is the best feeling approach? Adjusting the rigidbodies gravity? Or adjusting the velocity over time?

[silk night]

an impulse to the rigidbody

[summer bear]

And what if the player releases their button halfway through the jump? they should start to fall

the apex of the jump should essentially be dictated by how long the jump button is held, with a minimum and maximum

[silk night]

you can apply a continous force as long as the button is held

up to a certain amount of time per jump

[verbal dome]

When releasing early, you could limit the Y velocity or even set it to a negative value depending on how snappy you want it to feel

[summer bear]

Have you ever tried the gravity approach?

[wintry quarry]

Yeah that's what the link I gave you explains

The first thing you need to do is figure out the relationship between the two instances of the two scripts in the game are.

[dusk rapids]

hello guy I am new to unity and I was thinking about making a vr game do you think as a new unity user that doesn’t know how to script or design would be a good idea

[wintry quarry]

Start with something simpler

At least noe or two basic practice projects

[hybrid gust]

So, I'm using AsyncOperationHandle from the Addressable package to get references to items I want my game's containers to spawn I now feel like that was a bad idea? Once the asnyc operation has been completed, if I wanted to store the results of the operation in a seperate collection, IE, the player inventory I wouldn't be able to Release the operation handle right? Or am I understanding that incorrectly?

[idle saffron]

both objects are in the same scene. ive used references before to find values such as the x position of another object but never to find a variable from a script. as i have just started using c# yesterday my knowledge is almost nothing so i cant really understand either of the links too much despite how simple they probably are. i do not care about efficiency of the script, just need it to work. i know im not being very helpful. would i use get component? im just not sure at all ngl

[wintry quarry]

you can release the handle whenever you're done with it

[dusk rapids]

So do you think I should start with the unity tutorials

[wintry quarry]

ive used references before to find values such as the x position of another object but never to find a variable from a scrip
That is exactly the same thing. You use the same exact technique

The only difference is you are using your own custom component instead of a Transform.

[tepid portal]

uh u never followed any tutorial projects like the one brackeys have?

or unitys official tutorials?

unity have a pretty insane roadmap with step-by-steps and levels that i wish i knew about when starting out

[wintry quarry]

public Transform xform;
public MyScript myScript;

void Example() {
  float pos = xform.position.x;
  float whatever = myScript.whatever;
}```
Nothing is different except the names/types etc, depending on exactly what data you want.

[crisp halo]

Bro you are very good man

[idle saffron]

i still dont understand whta i would write tho. im in void update. when i do gameobject. it doesnt come up with any game objects so i know that is not what i am meant to do. sorry im being so useless

i know im meant to drag a reference into something under the script in unity, but i dunno

[wintry quarry]

when i do gameobject
Don't do that

use that variable

under LogicScript, i have defines the variable (public int playerScore;), in a seperate script i need to access this variable for a calculation. i just cant understand how i would make a refence in this context. if imake a variable it wont let me drag and drop likely because i define it as int. i just dont know. i am the most beginner of beginner. thx for helping so much

[wintry quarry]

In thje separate script you do:

public LogicScript myLogic;

Then assign it in the inspector

Then you can do myLogicScript.playerScore when you need the score

[wintry quarry]

is it playerscore or playerScore

pay careful attention

[naive pawn]

you used LogicScript.playerScore, meaning "the playerScore of the class LogicScript", but that doesn't exist

playerScore exists as a non-static field, meaning it exists for individual instances, not the class as a whole

[wintry quarry]

show us the actual code you wrote

[naive pawn]

you.. didn't do what praetor told you to do

[wintry quarry]

I can't guess at errors without seeing what you tried

[wintry quarry]

yeah that's not right

look at my example again

[naive pawn]

consider the difference between

Vector3 someVector = new Vector3(4, 1, -2);
Debug.Log(someVector.magnitude);
```and```cs
Debug.Log(Vector3.magnitude);

[idle saffron]

im sorry for being so confused. here is all of my relevant code. im sure it isnt to do with incorrect capitalization.

[naive pawn]

the second LogicScript in the second image is incorrect

[naive pawn]

read again what praetor wrote

[naive pawn]

(also consider this)

[wintry quarry]

Look at my example where I use the variable. Notice I do not write LogicScript there, I wrote myLogicScript which is the name of the variable.

In your case you named the variable Logic

@solar hill transform.RotateAround(Center.transform.position, OrbitVector, Time.deltaTime * OrbitSpeed);

Orbit vector is currently 0, 0, 1

I should mention it's a 2d game

[solar hill]

you need to cache the tangential velocity

[delicate ferry]

How

[solar hill]

gimme a sec

// get the center of rotation what wre oribiting around
Vector2 center = Center.transform.position;
// get current object position
Vector2 pos = transform.position;
// this is  the radius of your rotation circle.
Vector2 radius = pos - center;
// then we find the perpenducilar direction or rather the "tangent"
// this is basically the direction of the object while its rotating.
Vector2 tangent = new Vector2(-radius.y, radius.x).normalized;
// RotateAround according to the API uses degrees, but for the math you need radians so just convert it
float angularSpeed = OrbitSpeed * Mathf.Deg2Rad;
//simple enough formula, you multiple the angular speed with the radius
float speed = angularSpeed * radius.magnitude;
// this is then the exact velocity your object has while rotating 
Vector2 velocity = tangent * speed;

then when you need it to no longer orbit

transform.position += (Vector3)(velocity * Time.deltaTime);

[delicate ferry]

Thx

[solar hill]

actually woops that needs to be a vector3

[delicate ferry]

Is this the way to find the closest object?

        foreach (var Orbitable in GameObject.FindGameObjectsWithTag("Orbitable") {
            if ((Orbitable.transform.position - transform.position).sqrMagnitude < (ToOrbit.transform.position - transform.position).sqrMagnitude)
            {
               ToOrbit = Orbitable;
            }
        }

[grand snow]

Yes but ToOrbit is probably null before the first run right? (if so it needs to handle this case too)

[delicate ferry]

Yeah

[swift crag]

I was going to say that this would be a fine place to use LINQ (especially if you aren't that worried about performance)

but I forgot that MinBy is an extension method I wrote and not something built in

it'd look like this

var targets = GameObject.FindGameObjectsWithTag("Orbitable");
var closest = targets.MinBy(target => Vector3.Distance(target.transform.position, transform.position);

alas

[delicate ferry]

Oh thanks

[swift crag]

(this won't work without some extra code :p)

it's just the idea that came to mind

It does the same thing you're doing here – find whichever one has the smallest distance

[delicate ferry]

I have no idea why it orbits in an ellipse shape

[idle saffron]

hello, i am a beginner, how would i access the value of a variable in the logic script from a script in a prefab of the same scene? i know very little

[swift crag]

You'll need to get a reference to the component whose data you want to access.

(each thing in the inspector, like "Transform" or "Box Collider", is a component)

[swift crag]

Do both things exist in the scene when the game starts, or does one of them get spawned?

[idle saffron]

thanks for helping, one of them is spawned but due to it being a prefab, i cant drag and drop so i dont know how i would make a reference

[idle saffron]

would using a tag work?

[swift crag]

ah, then read this!

https://unity.huh.how/references/prefabs-referencing-components

[grand snow]

tags are good as a beginner i guess

[swift crag]

Whoever spawns the prefab should tell it about the other object

[grand snow]

MyCoolThing thing = Instantiate(thingPrefab);
thing.Init(this, otherThingy); //Call function on spawned instance component

this can be used to refer to yourself in code (learn more)

[chilly barn]

hey! how do i make the text and circle sharper? theyre getting softened rn and its supposed to be more pixel perfect instead of smoothed, going for that retro terminal type vibe

[grand snow]

TMP? Change the shader from sdf to a pixel one (there are a few tmp shaders to pick from)

circle is however its rendered and not relevent to this channel

#1391720450752516147 <-

[chilly barn]

ur right, my bad

[idle saffron]

thanks for helping but i still cant understand after looking on the website sent by Fen, here is my code for the instatiate, ive tried to get it into the format of having an = but i cant get it to work

[grand snow]

If pipe is GameObject then you can get a component after spawning it

[idle saffron]

it is a prefab

[grand snow]

Yes but if the variable is of type GameObject (as you can actually use a script type too)

@idle saffron

GameObject newPipe = Instantiate(pipe, somePos, someRotation);
MyComponent c = newPipe.GetComponent<MyComponent>();
c.DoCoolShit();

Spawn, keep reference, get some component, call function or assign to some variable

[idle saffron]

sorry for being useless as i have only just began using unity but i understand that the Pipe has to get told the reference by its spawner and store it as a variable (correct me if wrong), but i do not understand how it would transfer that to the Pipe or what c means in the code u hav provided (is it a placeholder?)

[grand snow]

Yea its a placeholder for whatever your component type is

the thing to understand is you can get the script/component instance from the new object and interact with it

c.coolVar = 15; or something

if that still confuses you then you need to learn more c# basics

[idle saffron]

ok

[eternal vale]

Unity is kinda hard for me to learn

Im switching to godot

🙁

[solar hill]

what do you expect us to tell you?

thats its going to be easier elsewhere?

because its not, youre free to use what you want, but if youre switching just because of the learning curve you are in for a rude awakening

[eternal vale]

I actually learned godot forst than unity

For me godot is much more easier than unity

[ivory bobcat]

Game development is difficult overall. Not sure how changing interfaces will make it any easier.

[smoky breach]

Is there a way to check with the new input system if any key or control is moved to get out of an idle anymation?

or to do press any key to start

[slender nymph]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/api/UnityEngine.InputSystem.Keyboard.html#UnityEngine_InputSystem_Keyboard_anyKey
also #🖱️┃input-system

[thin lotus]

I have this loop with a delay of 0.05, but when i test it, it appears much slower
public class Click : MonoBehaviour { float sizeincrease = 0.1f; int iterationCount = 3; public float delayBetweenSteps = 0.05f; void OnMouseOver() { if (Input.GetMouseButtonDown(0)) { StartCoroutine(ScaleOverTime()); } } IEnumerator ScaleOverTime() { for(int i = 0; i < iterationCount; i++) { transform.localScale += new Vector3(sizeincrease,sizeincrease,0); sizeincrease += 0.1f; yield return new WaitForSeconds(delayBetweenSteps); } } }

[barren tangle]

How can you even tell?

[thin lotus]

I figured it out

nvm

[meager gust]

you're going to have a much easier time with unity in the long run

you also just joined 3 days ago

[orchid wolf]

Isn't that too complicated?

[naive pawn]

not really, everyone has their own styles

[orchid wolf]

I mean, I would use Update() or FixedUpdate() and count deltaTime for my timer

[naive pawn]

WaitForSeconds(x) will wait for ≥x seconds, just according to how the frames line up. if you need to loop like this, you might not want to use WaitForSeconds at all

[meager gust]

yes really. unity is more developed and has more documentation and community archived posts than godot does

[orchid wolf]

python is the reason not to use godot

[meager gust]

godot has several languages one of them being C#

godot is open source and wonderful, but unity is the more mature engine

[naive pawn]

and godot supports another language that might make more sense to someone who has more experience with similar languages
and godot has a different node architecture that just might click easier instead of unity's model

[orchid wolf]

oh wow, I was teached to use python

[naive pawn]

i'm not saying godot is better or unity is worse, but everyone has their own pre-made preferences

sometimes those align better with something else

[naive pawn]

the common pattern for this goes something like this @thin lotus

float elapsedTime = 0;
while (/* some condition */) {
  while (elapsedTime >= /* time per iteration */) {
    /* do thing */
    elapsedTime -= /* time per iteration */;
  }
  elapsedTime += Time.deltaTime;
}

[viral bobcat]

I am working on player physics of a FPS and I check cc.isGrounded before allowing a jump. For some reason I cannot jump at all whilst standing still (even after moving) and my jumps are far flatter than they should be when input whilst moving. Removing the cc.isGrounded == true condition allows a regular jump which moves much higher. Does cc.isGrounded just suck or is there something else I need to adjust?

[frail hawk]

post some code

[eternal vale]

hehe im back , and i enjoyed unity for time being :3

How do I complicately design this ui with custom stuff

it looks plain

and pain

[naive pawn]

design how you want it to look first, then implement it

also, this is a code channel

once you figure out what you want, if you're having issues, ask in #📲┃ui-ux

[naive pawn]

make sure you only have one Move per update

[viral bobcat]

thanks I did and now i can at least jump even whilst standing still

[austere kraken]

how you are too much active here bro

[solar hill]

People who are active here are typically also working on their own projects at the same time

[ionic zealot]

Helloo, laddies! Im having some trouble using the animator. I have a few transitions but the main problem is that they queue. For example, if im reloading and am spamming the shoot button, itll wait for the reload to happen, then shoot as many times as i pressed, yk? how can i fix that?

[frail hawk]

if you have hasExitTime checked, the animation will play until the end

[naive pawn]

this is #💻┃code-beginner

go ask in #🏃┃animation

[ionic zealot]

My bad, thanks

[delicate ferry]

What are the conditions for onCollisionEnter2D to get called? I have two box collider2d's, one of them has a script with that method yet it isn't called

[frosty hound]

A rigidbody on one of them

Or specifically a rigidbody2D

using UnityEngine;

[RequireComponent(typeof(CharacterController))]
public class PlayerMovement : MonoBehaviour

    // References
    private CharacterController cc;

    private Vector3 velocity;
    private float currentHeight;


    private void Awake()
    {
        cc = GetComponent<CharacterController>();
        inputHandler = GetComponentInParent<InputHandler>();
        cameraTransform = GetComponentInChildren<Camera>().transform;
    }

    private void Update()

        if (inputHandler == null) return;

        velocity.x = 0f;
        velocity.z = 0f;
        HandleJump();
        ApplyGravity();
        Debug.Log(velocity.y + "|" + cc.isGrounded);
        cc.Move(new Vector3(velocity.x, velocity.y, velocity.z) * Time.deltaTime);
    }



    private void HandleJump()
    {

        if (inputHandler.JumpPressed && cc.isGrounded) // && cc.isGrounded (makes jump flatter but prevents air jumps)
        {
            velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
    }

    private void ApplyGravity()
    {
        if (cc.isGrounded && velocity.y <= 0)
        {
            velocity.y = -2f;
        }
        else
        {
            velocity.y += gravity * Time.deltaTime;
        }
    }
}

Removing cc.isGrounded in HandleJump() makes the jump higher but I do not understand why

Can somebody please explain why?

[delicate ferry]

So I'll create a rigid body with zero gravity

Though why does it neeed a rigidbody?

[frosty hound]

Because physics?

[delicate ferry]

What if you wanna just invoke a function when 2 things start overlapping?

[frosty hound]

Use the OnTriggerEnter version instead, if you don't things to physically collide. You also have to set the IsTrigger flag on the collider.

[delicate ferry]

thx

[delicate ferry]

On both colliders?

[naive pawn]

https://unity.huh.how/physics-messages/collision-matrix-2d

[naive pawn]

on at least one of them

you still need an rb
