[languid spire]

wait. it's a public array. So the inspector value will be leading

is there a reason it's public ?

[faint topaz]

Uh, not really

[languid spire]

then make it private

[faint topaz]

Alr

@languid spire

It needed to be public

[languid spire]

The TMP_Text needs to be public, frases does not

[faint topaz]

Aaaaand now it directly doesn't work

Alr i'll try that

[languid spire]

you'll need to reassign the TMP_Text in the inspector

[rich adder]

did you actually assign it

[faint topaz]

I think I didn't

I made this with a friend that understands more of Unity than me during night

Im getting started into unity

[fluid kiln]

why is it not letting me click a button from the ui? it worked on the scene i created it, but not now in a completely new scene

[rich adder]

you need Event System in new scene

[languid spire]

EventSystem missing?

[main anchor]

for some reason, when i rotate my camera, only the camera rotates, how can i make it so the player rotates along with the camera aswell?

https://hastebin.com/share/ovehumuxer.csharp - My player movement script if you wanted to take a look at it :)

[fluid kiln]

tysm worked

[rich adder]

your player should be rotating and the camera with it, not the otherway around

[main anchor]

how could i fix this?

[rich adder]

do the thing I just said

[lethal bolt]

Sometimes i dont even know where to start. It dosent set IsGrounded to true

[rich adder]

have you tried starting by debugging ?

also why are you doing a FindByType then a GetComponent on the same component

[lethal bolt]

Because

it looks more clean

[rich adder]

what?

how exactly does Getting component on an already grabbed component of the same type "looks clean"

[lethal bolt]

I dont know

im trying

[rich adder]

I mean don't just randomly put stuff there 🤷‍♂️

[lethal bolt]

I made sense while making the script

[rich adder]

well the GetComponent isn't needed if you already find by Type

[gloomy jacinth]

I am trying to add post proccesing effects to my game but they do not show up on screen. what do i do to fix it?

[rich adder]

@lethal bolt anyway have you check if this script/function is even running ?

[rich adder]

this is a coding channel, what question do you have about coding?

[robust kelp]

can someone explain to me why is drag like that? https://gdl.space/hajijorodi.cs

mb

[rich adder]

no worrries

just looks weird on mobile

[rich adder]

did you check the grounded var

if you are using Unity 2022 you can use the Analysis window for Physics Debug, find the Spherecast and enable Casts

[lethal bolt]

Yes and i found out the problem 👍

[rich adder]

what was the problem?

[lethal bolt]

Or i dont really know what the problem was but i simplified the script

[rich adder]

oh so the thing I told you was unnecessary turned out to cause a problem, what a coincidence

that or you forgot to use a Rigidbody lol

[robust kelp]

holy shit this helps a lot ❤️

[lethal bolt]

Lol, no.

It was the "Unnecessary" part lol

[rich adder]

so glad unity has added it 😅 took so many versions to get something out the box

[robust kelp]

yea

[rocky canyon]

whata.whata coincidence 🫣

[rich adder]

waddayakno

[robust kelp]

thats a sphere btw

[rocky canyon]

gotta fix this door script now :D, use interfaces and enums

[rich adder]

hah yeah its in hell

[rocky canyon]

no sir.. that is a line segment.. and some other ray chilling in there i think

[rich adder]

wait checked off spherecast and it shows a line ?

that don't look right

[rocky canyon]

or the ray's handle broke off and ended up there

did u write GUI code for tha?

[rich adder]

I'm surprised you didn't make a door asset for assetstore yet

[rocky canyon]

speedTutor has1

Mute

[rich adder]

spammy

[rocky canyon]

wanna see something ugly?

[rich adder]

sure, is it my code from years ago

[rocky canyon]

probably ¯_(ツ)_/¯

[rich adder]

something I would've done for sure ain't gonna lie

[rocky canyon]

atleast once

[rich adder]

at least

[rocky canyon]

i got this, i can make this 10 lines long, max

[rich adder]

Hey at least you had an inventory, i just crammed it all my monolith player class

[rocky canyon]

i didnt wanna screw guy over like that

he'd definitely woulda came bcak w/ problems

atleast my snippet can atleast be scaled a little bit 🤏

[rich adder]

you ever get paralysis by analysis cause so many ways to do something 😛

[rocky canyon]

i got all this stuff already actually

just gotta add an enum for the door colors

[rich adder]

You could make it without enum tbh

[rocky canyon]

ints and index

[rich adder]

just match Scriptable Objects

[rocky canyon]

oh no.. im avoiding those

[rich adder]

😮

[rocky canyon]

structs and classes r fine by me

i have 1* for my player settings

[rich adder]

but a key can be an asset you drag n drop into the door slot

so you wont have to create a new enum for new key type / door type

some can have 3 keys

[rocky canyon]

its pretty chunky

[rich adder]

you missing out Scriptable Objects are goated for this

[rich adder]

well yeah you need to split those into structs, at least I would

[lime pewter]

Hey all! I am currently working on a cellular automata liquid script and am trying to create a "new liquid" on the tilemap grid, so essentially trying to align a gameobject to a tilemap using the "WorldToCell" parameter on the vector3. However it seems to be 0.5 off on both axis from the tilemap it is referencing, if anyone has any idea as to why the debug rays are showing as they should be however both the collider attached and the sprite are off-centered while the "offset" of the box collider says (0, 0) any help would be amazing! Below is the example of the gameobject offcentered.

[rocky canyon]

u think?

i dont see how structs would be helpful for all the playercontroller code

[lime pewter]

newWater.transform.position = blockTilemap.WorldToCell(new Vector3(transform.position.x + direction.x, transform.position.y + direction.y, transform.position.z));
        

[rich adder]

but still I think a SO key door system can be pretty cool, I might just make it a free asset rq 😛

you can have like doors that have specific "Recipe" of "keys"

[rich adder]

looks correct to me

cell positions are at the corners

unless i misunderstood what you're asking

you prob want to CellCenter

or w/e is called

[lime pewter]

well the collider highlighted in the image is supposed to be aligned with the red lines.

Oh that might be why, I'll try that, thanks!

[rich adder]

https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.GetCellCenterWorld.html I think this

[rocky canyon]

unity pestering me

no way i know of to stop it besides commenting it out

[night owl]

@/navarone all errors are gone!

[rich adder]

well why aren't you using the value 😛

[night owl]

thanks :)))

[rich adder]

nicee. you fixed the code editor though ?

[rocky canyon]

its a WIP and that variable is nested quite happily in the rest of that script

[night owl]

yup downloaded the community one ahahah much better

i was missing out damn

[rocky canyon]

i guess its a good thing,, its like a todo notification

[lime pewter]

worked perfectly, thanks!

[rich adder]

indeed its a more mature application, plus its a real IDE

[opaque bough]

this code just says if the player is in trigger and you click E, then set gotGas to true, the player is in trigger because the bool says so, but when i click E it dosent set gotGas to true

[fervent abyss]

what will take more processing power?

1. bool test = BoolReturnMethod() in Awake()
then 
void Update(){ 
    if(test{
        Debug.Log("Bool");
    }
}

or

2. void Update(){ 
    if(BoolReturnMethod(){
        Debug.Log("Bool");
    }
}

[languid spire]

obviously 2.

[fervent abyss]

i just realized

[summer stump]

You should look up the docs for the other OnTrigger methods
Enter is only true for a single frame, and never again until after Exit is called and the collider reenters the trigger

[languid spire]

that is because that is not what that code says or does

[opaque bough]

wdym

what dont it say

oh nvrm the ontriggerstay thing worked

[languid spire]

it does not say 'this code just says if the player is in trigger and you click E'

[astral falcon]

you are mixing up one time event methods with update(). Your Input... line is being checked in the frame of your trigger has been entered. if you are as fast as the physics engine and hit the button within that frame, it will work, but thats not what you want. Obviously you should look into the basic tutorials on learn.unity.com for example to get, what the engine is actually doing, when and how often its executing its builtin methods etc etc

[summer grail]

How would set up an object to have a trigger and still be solid?

And how would I have the trigger only detect specific objects (like a bullet for example)

[polar acorn]

Those are contradictory goals

Triggers, by definition, are not solid

[summer stump]

Have a non-trigger collider as well.

Validate which object in OnTriggerEnter before doing anything. Using tags, layers, or component checks

[summer grail]

Alr thank you

[ruby ember]

hi everyone so i have a problem that i don't know how can i do

is about saving the selected button

like when you select monochrome and you leave the game
and when you open the game monochrome button is still selected

https://hastebin.com/share/jewaqenuno.csharp

[swift crag]

this isn't really saving a selected button

you just need to save a value, like a number or a string

you can use PlayerPrefs to store small amounts of data

[swift crag]

What does clicking these buttons do in your code?

[ruby ember]

i tried that but it didn't work for me or maybe i didn't do it right

[ruby ember]

for example

it comes with default

when you click monochrome it changes color to blue and default changes to white

https://cdn.discordapp.com/attachments/1218990324039553175/1249245880154853468/Security_Night_-_Menu_-_Windows_Mac_Linux_-_Unity_2023.2.3f1___DX11__2024-06-09_00-15-36.mp4?ex=66674323&is=6665f1a3&hm=2f4b9c9df9ba4cfd89e44641ff83f4108a4016487040bea66551a701005ace3c&

i made it work

[swift crag]

that's which UI button is currently selected -- but that doesn't really correspond to which option is picked

[ruby ember]

but the problem is that idk how to make saving

[swift crag]

it's just which button will be pressed if you hit enter

You should use the Toggle component

You can put all of them into a Toggle Group

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/script-ToggleGroup.html

[ruby ember]

watch the video to understand what im talking about

[swift crag]

The only annoying thing is that you'll need to add a separate graphic for when the toggle is checked

[untold raptor]

ArgumentException: Input Button No Control is not setup.
To change the input settings use: Edit -> Settings -> Input

can anyone help with this please.

[ruby ember]

also im using buttons

not a toggle

[swift crag]

Yes. That's why I suggested switching to using toggles.

the "selected" color is just telling you that you've got that Selectable object selected

like, for keyboard navigation

You could just change the actual color of the text, I suppose

When you click a button, reset all of their colors to white, then color the one you clicked blue

When you start the game, look at the saved setting and use that to decide which button to color

[ruby ember]

i used the same text to change color

[swift crag]

show me your code; i need to see what you're actually doing here

[ruby ember]

https://hastebin.com/share/jewaqenuno.csharp

[swift crag]

ah, okay, so you are already changing the actual text color

I thought that was just the color of a selected button; my bad

Anyway, I would suggest rearranging your code

Create a function that reads the player pref string and sets the button colors

Make DefaultButton/etc. do two things:

• set the playerpref string
• call the new function

When the game starts, call that new function

the new function can also set DefaultMode/MonochromeMode/etc. based on the string

[ruby ember]

https://hastebin.com/share/yuzoqizano.csharp

i used this to make the save

but idk if i did it wrong

[ivory bobcat]

Maybe describe how, why and when the error is generated.

[untold raptor]

its on startup but ive just figured it out, the controls are missing from the input manager

[young fossil]

Hi, would like some advice for starting a project that is very UI heavy. 2D puzzle

[teal viper]

The advice is: don't make it ui heavy.

[young fossil]

Seems more like a statement without any point than advice

[summer stump]

Nope

Why does it have to be ui heavy?

[teal viper]

Well, your question didn't provide any context either

[night owl]

hi the death animation endlessly repeats in my game and im following a tutorial that has a box that is can/cant transition to self but i dont see the box on my end. I was wondering how i could get it or if someone could help me correct a destroy command?

[worn garnet]

I need some help with a system in my game:

oops

[teal viper]

Well, why does it transition into self in the first place? That doesn't seem correct.

[young fossil]

Plenty of context while staying open-ended. Remember we are in #💻┃code-beginner too, this is adds to the context as well. I don't see the advantage of writing advice that doesn't serve to help, either that or you maybe you don't know how to. Leaning on the former. Wastes both of our times

[summer stump]

Please don't

Just provide the context

[night owl]

well i tried setting it as a trigger but that didnt work so it is currently a bool which i think is the reason it keeps repeating?

[summer stump]

Why is it ui heavy. If you don't want to answer, then you should not waste the time of others.
It is unanswerable until we know the extent of the ui, the answers will be different in different circumstances

But you could google the canvas optimization guide from unity yourself if you want generics

[teal viper]

Can you explain why it needs to be ui heavy? Are you planning to make the main gameplay elements with ui?

[worn garnet]

I have a raycast system where if the raycast is hitting a certain tagged object, it set a boolean to true of false depending on if its hitting it or not, but no matter if the raycast is hitting the enemy or not, the boolian will stay at false

[teal viper]

A trigger should work exactly like a bool, just one time. If that didn't work, you should debug it instead of changing to an incorrect solution. But also maybe consider why it can transition into itself. Are you using "from any state" or something?

[young fossil]

Didn't come here to argue, came here to get advice. It would be UI heavy since I wanted it to be a puzzle game which is all themed inside a computer (OS). There are no planned interactions outside of the computer. I guess a good example would be something like Home Safety Hotline or Space Warlord Organ Trading Simulator.

[summer stump]

It doesn't NEED to be ui though. Most puzzle games would not be.

The best way to deal with this would be to NOT make it ui, so that it is more performant

[swift crag]

If you're pointing and clicking around a computer then UI components make sense

[summer stump]

But as I said, unity has a canvas optimization guide

[swift crag]

in that case I'm not sure there's any specific advice, really

[young fossil]

Yep, the whole thing is UI. I wanted to go for Unity since I have experience in this engine and I would like to play with the shaders (Like an old CRT filter and such)

[swift crag]

beyond deactivating things you aren't using or splitting into multiple canvases

[teal viper]

Right. Well, that's the kind of context that you should have provided at the beginning. This kinds of game are perhaps worth building entirely with ui.

[swift crag]

I guess I'm not sure what kind of advice you're looking for

[young fossil]

Weirdly people were very quick to say not to do it. Considering other engines actually

[swift crag]

you've got a very broad subject

[summer stump]

https://unity.com/how-to/unity-ui-optimization-tips

This is the guide I was talking about

[night owl]

ohh ok so it goes entry-> idle->death and the idle is not animated. i didnt use the any state block though.

[teal viper]

Does the death state have any transitions out of it?

[night owl]

no it does not

is that the issue LMAOO

thats my bad then thanks

[teal viper]

Then it shouldn't be transitioning into itself? Is it looping perhaps?

Make sure the animation is not set to looping.

[young fossil]

Well, if other engines deal with UI centric games better, then I could go and use those. Also considering the architecture and how UI is based around Unity events, maybe it would be best to use Unity events other the kinds to compliment it

Also if the engine comes packed with things, such as physics, will it affect file size or performance even if I don't use that feature?

[swift crag]

file size, yes, but it's not a massive baseline

you're not spending 3GB on engine code

[night owl]

omg yes that was it thank you! "loop time" was selected, i left it checked bc i thought thats what the guy had in the video but i must have missed it :)

[swift crag]

and physics updates with no physics objects are going to be extremely cheap

[young fossil]

Thanks very useful

Is there a way to strip it down?

I know there is an extesnions feature

And some stuff is packed into there

[swift crag]

no, and I would focus more on making your game than trying to slice off every last kilobyte of engine code

[young fossil]

Yea true, but hopefully you understand why I ask these questions

[worn garnet]

I have a piece of code in my game thats not working, it supposed to set a boolian active when a ray is hitting a enemy, but the boolian constantly stays deactivated, no matter if im looking at the enemy or not, heres my code for it: if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out RaycastHit hitinfo, 20f))
{
if (hitinfo.transform.CompareTag("Enemy")) {
IfLookingAtEnemy = true;
} else {IfLookingAtEnemy = false;}

[young fossil]

So UI affects performance more than physical gameobjects?

[swift crag]

UI is game objects -- it's just that you're using UI renderers instead of, say, MeshRenderer

The cost of re-drawing the UI grows with the amount of UI renderers you have

which is true for basically everything, really

[young fossil]

Okay, correction then, UI over sprites

[summer stump]

Not necessarily. I imagined something like portal or myst immediately

[swift crag]

I was thinking of a sliding tile puzzle game lol

[young fossil]

Why can't I put a thumbs up? Weird lol

[swift crag]

You should use the profiler to analyze how long it takes to re-draw your UI. If it starts becoming an issue, you can look at splitting into smaller canvases

I use one huge-ass canvas for my game's entire menu

[young fossil]

Yea, sorry, I should make it clearer next time

[swift crag]

But I also deactivate menu screens that aren't currently in use

there are 291 game objects in my main menu, and that's before I instantiate any sub-menus (like individual settings screens)

[summer stump]

I think what dlich and I were thinking at first was the common trap people fall into, thinking ALL 2d games make sense as ui

Like a 2d platformer as entirely canvas based

It comes up more often than I would have thought before helping here

[young fossil]

I have always done this too, seems the best way. I can imagine a HUD and Menu canvas being separate, but not sure what else can be separated after that?

[young fossil]

Oh lol... I admit I did not think of that

[swift crag]

I'm not sure there's a big difference between:

• Canvas
  • Huge blob of UI elements (activated)
  • Huge blob of UI elements (deactivated)
  • Huge blob of UI elements (deactivated)
  • Huge blob of UI elements (deactivated)

and

• Canvas
• Canvas (deactivated)
• Canvas (deactivated)
• Canvas (deactivated)

Multiple canvases will be relevant if you have several distinct UI areas

obviously "HUD" and "Menu" is a common split

but think about an RTS

[rocky gale]

Is 2d not already just on a canvas

The characters are spritrs

[swift crag]

no, you're using sprite renderers

those aren't UI renderers

[rocky gale]

Oh

[swift crag]

UI is a separate system

[rocky gale]

Oh

[swift crag]

you can have the minimap, the unit info panel, the top bar

[rocky gale]

Didn’t know that

[shy ruin]

I have a car with wheel colliders, the car's mass is 2500 and the wheels have a mass of 20. The trunk is supposed to hold the wood that the player collects which are rigidbodies weighing up to 500 mass EACH. For some reason the heavy rigidbodys cause the car to start floating and the suspension to up to max, how do I fix this?

[young fossil]

Hmm, well Fen, for my case I'm imagining each "window" inside this computer's fictional OS to be a canvas... maybe a bad idea, idk

Since you can "minimise" them

[swift crag]

that sounds reasonable

windows don't really interact with each other

especially once you get into automatic layout

each window is totally independent

putting a huge text component in one window won't make another window grow or rearrange itself

[teal viper]

Try debugging things. Add a debug inside the raycast if block and see if it prints.

[rocky gale]

Debug = GOAT

When in doubt debug as they say

[midnight maple]

Hi all. I am more of an XR designer than a developer, so working with code is not my strong suit. Sorry if this isn't the right channel for Unity error troubleshooting, but does anyone know what this error means and how to fix it? Originally, I thought it was because I forgot to switch the build settings back to "windows, mac, linux". It seemed to have solved the problem the first time, but it's back to causing problems on play mode and showing the same error message.

[rocky gale]

An index in one of your scripts is greater than the size of the array

Can we see the code

[midnight maple]

When I click on the error, this is the line of code it takes me to.

[young fossil]

Off topic to programming but just wanna say, I tried reacting to your messages a second ago and it wasn't working, it kept shaking and removing it. So I looked it up and just realised that it means the person blocks you. That is so funny and stupid that Discord has such an anti-feature, that allows you to test if someone "privately" and "anonymously" blocks someone. Terrible breach of privacy, could've been fixed by not showing the reaction to the user and but still to others instead.

Anyway, thanks to those you helped, also sorry for not being clearer before, I didnt think of people using Canvas like Sprites and other crazy things. Sorry to @teal viper @summer stump and still appreciate the efforts to help

[summer stump]

Debug the lenth of the list (array?) and index

[rocky gale]

What’s m_views

[summer stump]

I'm not sure if you mean me. But I have not blocked you

But either way, no worries

[rocky gale]

Look at aethenosity man, so inspirational

[teal viper]

I'm not blocking you, so no clue why you can't react.

[young fossil]

Before, I tried reacting and it wasn't letting me. I looked it up and it says that. Could've been glitched but I just assumed I pissed you off (I literally block people like that so understandable if so). But yea, maybe a glitch or whatever, still what a grand discovery, makes me think how many people realised I blocked them

[summer stump]

I have had that happen before. Very odd

[midnight maple]

When I look it up, it says materialized view? idk

[midnight maple]

And I tried that, but I don't see anything that sticks out. Maybe I'm not debugging correctly. I'm guessing it has to do with one of the materials maybe?

[summer stump]

Well what values did the log say?

projectileGun is null

[gloomy jacinth]

How do i set it?

[ivory bobcat]

Preferably in the inspector

[gloomy jacinth]

Does the instance need to be a prefab?

Or the gameobject with the script in it

Oh i got it!

It needed to be the instance with the script i was referencing

Is this possible to do in a reference?

Is that possible or do i have to divide it into one?

Or 3 parts

[main anchor]

sorry to ask, but do you know what i could do to make the player rotate and the camera with it?

[gloomy jacinth]

@ivory bobcat How can i get the true or false statement of the other script to bring it into this reference?

I want it to change the statement to tell if i can shoot or not. How do i get it from my weapon script and store it here?

Can someone help me with my script?

Im trying to get a true or false input from another script using references.

[summer stump]

https://unity.huh.how/references

Drag and drop (serialized references) if you can

You really should just stop and do the learn.unity.com site I keep linking though. It goes over all the basics like this. You would be up to speed in a few days and have a broad foundation to build from

[plain mortar]

this is for a 2d game

[midnight maple]

I wasn't sure how to look that up, but after doing some more digging, I discovered that others were having a similar issue! I found a workaround on this page. https://forum.unity.com/threads/xrpass-getviewport-exceptions-in-editor.1577916/

[rich adder]

did you parent the camera to the player?

[night owl]

hello i was wondering if someone could help, the enemy death animation is played and then i want the enemy to go away so i used a destroy(obj) but now when i attack the enemy nothing happens (neither death animation or destroy(obj)

this is the block of code

    void Update()
    {
        if (health <= 0)
        {
            anim.SetBool("isDead", true);
            Debug.Log("Enemy is dead");
            Destroy(anim);
        }
        
    }

With the Destroy(anim); line commented out the script works and upon attack the animation goes off

[main anchor]

no, the camera is parented to an empty game object called "orientation", i tried parenting it to the player object and still no result

[rich adder]

and is orientation child of player ?

[main anchor]

yes, this is what my player hierarchy looks like

[rich adder]

so are you rotating Player/Player Controller?

[rich adder]

btw this only destroys the animator component

[night owl]

oh ok so what is the word i would use for the whole object?

[rich adder]

every script on a gameobject is a Component
https://docs.unity3d.com/ScriptReference/Component-gameObject.html

[night owl]

ohhh so game object ok ty

[night owl]

i have another question

i have an attack point which currently uses overlap circle to show when the weapon has hit the enemy. The weapon is kind of like a rope, like wonderwoman lasso, so it shoots out. is there a way i could have the circle made into a polygon that can be shaped around it or move with the rope?
i was looking into this https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCollider.html as well

or is there a way to make a polygon collider 2d that then is used as the attack point but it doesnt react to physics so it can pass into/thru the enemy

[indigo schooner]

can anyone help me with something quick

I am very new to unity and my elephant is floating and i dont know why

there is a sphere mesh collider that is nowhere to be found in the inspector but it's there

i used the instructions from this video https://www.youtube.com/watch?v=1uW-GbHrtQc

[graceful lintel]

weird, cant tell much from your picture but I think the sphere collider might be in the camera? if its not check all the childs

[indigo schooner]

its not in the camera and the elephant is the only child

[graceful lintel]

if it appears only when PLayer is selected check PLayer, playyyy and Main Camera

[indigo schooner]

Ive checked everything

I'm not exactly sure what I'm looking for though

[graceful lintel]

Sphere collider

[indigo schooner]

But when I disable all of the components it's still there

[graceful lintel]

huh I guess try restarting Unity?

its impossible for a sphere collider to be visible if there isnt a component of it in there

[indigo schooner]

think again

ill try restarting

still there

Could it be in the script somehow? i just copied and pasted it

and it's not in PLayer

[graceful lintel]

oh hey

try removing Character controller

even if its disabled its collider is still visible

[indigo schooner]

"Can't remove CharacterController because PlayerMovement (Script) depends on it"

[wintry quarry]

The CharacterController will look like a sphere if you set the height to 0

Also yeah looks like your script has [RequireComponent(typeof(CharacterController))]

[graceful lintel]

Ye, that's my best bet.

[indigo schooner]

what should i do

I GOT IT NEVERMIND

THANK YOU SO MUCH

[graceful lintel]

[night owl]

hi does anyone know why i cant resize this overlap circle?

code:

    {
        Collider2D[] enemy = Physics2D.OverlapCircleAll(attackPoint.transform.position, radius, enemies);
        
        foreach (Collider2D enemyGameobject in enemy)
        {
            Debug.Log("Hit enemy");
            enemyGameobject.GetComponent<EnemyHealth>().health -= damage;
        }
    }

im able to move it around on x/y but the scaling doesn't seem to do anything?

[wintry quarry]

wdym by "scaling"?

OverlapCircle uses whatever radius you give it

in this case, the radius variable

[night owl]

oh hmm the radius is what im trying to modify

[wintry quarry]

well how are you modifying it

[night owl]

unity transform under inspector

[wintry quarry]

Transform doesn't have a radius field

so idk what you're talking about

[wintry quarry]

scaling the transform is not going to affect this radius variable.

only changing that variable will change it

[night owl]

https://gdl.space/bujusopaci.cs

[wintry quarry]

If you want to change radius, change radius

[polar acorn]

So, radius does not change in code, so changing it in the inspector will change the value of it.

[night owl]

oh interesting i swear it used to work tho and in the tutorial i used it worked there as well

[wintry quarry]

The Transform scale is completely unrelated

[wintry quarry]

what you are decribing makes no sense whatsoever

[night owl]

sorry

[wintry quarry]

something was different when it worked

maybe code that actually multiplied the Transform scale by the radius

There's nothing to apologize for

[summer stump]

I promise it did not work like that in the tutorial unless it READ from the transform and used that in the radius

Ah, basically what praetor said.
And yeah, nothing wrong with learning

[gray gorge]

completely unrelated seeing as you resolved your issue but helpful to know regardless; do you know about [SerializeField]?

[night owl]

okok this was totally my mistake then i was trying to adjust the x and y values seperately but the radius control is within the actual attack script

[night owl]

no i dont know at all

I was hoping i could just change it to this (and added width and height float var)

Collider2D[] enemy = Physics2D.OverlapBoxAll(attackPoint.transform.position, width, height, enemies);

but it gave the error that "cannot convert from float to unity engine vector2

[wintry quarry]

make a Vector2

it wanbts a Vector2

e.g. new Vector2(width, height)

[gray gorge]

so I assume the reason that you set things like attackTime public is so that you can change them in the editor easily, right? super convenient. But public is actually problematic because that variable can be modified by other code when you just want that code "encapsulated" so to speak. If, rather than public float attackTime you replace it with [SerializeField] float attackTime that code can't be modified anywhere else by any other scripts (e.g. private) AND you still get to mess with it in the editor like you're used to

[gray gorge]

or i could just be completely wrong and spreading misinformation so someone else feel free to correct me

[night owl]

thanks that actually makes sense to me

so why wouldnt u use the [serializefield] always

just bc it's not needed?

[wintry quarry]

Best practice is to do that

public fields are bad form

sometimes you do need to modify things from outside though, and that's where public methods and public properties come into play

[gray gorge]

did you resolve this?

[night owl]

i wasnt exactly sure where to put it but i am testing it rn

even though i made it a box overlap only the radius control seems to work? and like change the size

but its also still a circle which im also confused about

oh wait

the gizmo is still saying sphere i think

[wintry quarry]

there won't be a gizmo for your code

the gizmo, if there is one, will be from some component on the object

maybe a CircleCollider for example

[night owl]

i tried putting a polygon collider on the attack point but i couldnt figure out how to make it not solid

[wintry quarry]

what ar eyou trying to do

back up and start with that

[night owl]

yeah this is what i had put a bit earlier

its honestly poorly explained now that im looking at it

ill try and rephrase with a tldr

[keen pecan]

Does anyone know a good way to have unity rotation work in WebGL?

[wintry quarry]

yes you could use a trigger collider

[keen pecan]

(right now when i reach the bounds it just leaves the game screen)

[wintry quarry]

but it honestly is worse to use colliders for this than to use queries like OverlapXXX

[keen pecan]

(and when I set it I cant fully rotate)

[wintry quarry]

This is an extremely vague question. Can you elaborate on what you mean?

What does rotation have to do with "bounds"?

rotation of what

[keen pecan]

So my rotation is based on my mouse and when i have the game on itch the mouse leaves the game and I cant rotate anymore

[wintry quarry]

lock your cursor

[keen pecan]

Should that work on WebGL too?

[wintry quarry]

Of course

https://docs.unity3d.com/ScriptReference/CursorLockMode.html

[keen pecan]

Oh lets go it worked

Thanks

I was setting screen bounds but not locking the cursor

[silent vault]

Good idea. Thanks!

[night owl]

this is the line i have currently worked out

        Collider2D[] enemy = Physics2D.OverlapCollider(attackPoint, enemies);

but it returns with the error of no overload for method overlapcollider takes 2 arguements. so i tried having radius there and the position transform as before as well as width/height. I also found on a forum someone using filter and results but that did not help the 2 arguments thing

[zenith cypress]

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCollider.html

[wintry quarry]

Why are you guessing

[night owl]

ive already read this page over and over but i just dont understand :(

[wintry quarry]

instead of checking what the parameters actually are

[wintry quarry]

Look at the parameter list

and provide what it actually needs

public static int OverlapCollider(Collider2D collider, ContactFilter2D contactFilter, Collider2D[] results);```

^ They write this so you know what parameters go into it and what it returns

[night owl]

ok ok thank you i will try again

but not just guessing oops

[night owl]

based on this,

public static int Physics2D.OverlapCollider(PolygonCollider2D coll, Physics2D physics2D, Collider2D[] enemies);

still returns with errors for Physics2D.OverlapCollider

is enemies at the end just supposed to be a number?

[summer stump]

No, it is a Collider2D array

You create the array and pass it in

[night owl]

so the "Collider2D[]" generates the array?

[summer stump]

It is the type for an array

GameObject[] is an array of gameobjects

[] is the syntax for array

You have to create the array

[wintry quarry]

what errors?

[wintry quarry]

No it says the type : Collider2D[]

that's just telling you waht type to use

you have to provide an array there

[summer stump]

You might wanna show the code you actually wrote instead of the method signature

[night owl]

okay

Ok, that is not at all what you should do

You are declaring a method for some reason there
Just completely delete line 47

If the docs say the signature is OverlapCollider(Collider2D collider, ContactFilter2D contactFilter, Collider2D[] results);
Then you write Physics2D.OverlapCollider(myCollider, myContactFilter, myArray);

You do not include types. You do not have public static int

You just call the method with the right parameters

no ones responded to me all day...

I even asked twice

I see this

And no other messages

[plain mortar]

I deleted all of them at this point, thought my format was wrong

[summer stump]

Ah, gotcha.
Well I did not see them, and you have not re-asked it. So nothing anyone can really do 🤷‍♂️

[plain mortar]

I was gonna reread the rules and post again

[plain mortar]

Gotcha.

I'm having trouble with creating an arc for the bunny (user controlled). All the code and more detailed explanation is posted here: https://forum.unity.com/threads/arc-jump-not-working.1602186/

unity forum

[summer stump]

People generally don't want to go to links, so maybe that was why it was skipped over.

But in your link you say:

but the bunny doesnt move horizontally left or right, only horizontally

Is there a mistake there? I am confused

Do you mean only vertically?

[plain mortar]

yeah, only vertically

I edited it

[summer stump]

Well, I am about to go to bed, someone will hopefully help.
I suggest adding a log after each operation and see if each step is what you expect.
I would need to test the code to actually see what is going on myself. Can't do it in my head

[eternal needle]

you should add debugs or attach the debugger to see what these values are. You can even visualize the direction with Debug.DrawRay. Though really i bet the issue is with that first line
Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
This is probably just giving you the camera position

[plain mortar]

I did add debugs and the angle was given properly, straight up was 90, far left was 180 and far right was 0. Its not applying horizontal force for some reason, just vertical

[eternal needle]

Show the debugs you've added, I highly doubt you are getting anything other than a fixed number for this angle if the character is staying still

another thing, this clamping probably isnt desirable because you are clamping all negative angles to 45. Going from -179 to 179 degrees is a very very small difference but your code will clamp it to 45 or 135 respectively. Which is basically the opposite direction

[eternal needle]

the docs for ScreenToWorldPoint also show how to use it https://docs.unity3d.com/ScriptReference/Camera.ScreenToWorldPoint.html. There is something very important you are missing

[zinc shuttle]

how to build the game? i am getting errors, building android game.
and error are What went wrong:

what component do i install and how?

[plain mortar]

I already told you the angles are good

dont know why my mouse cursor isnt there, but at 180 my mouse is to the left of the chracter, at 0 its to the right, at 90 its directly top

this wasnt even the issue i described

did you even test it, genunely curious...

[eternal needle]

i meant show the actual code for the debugs. Also use Debug.DrawRay to visualize the direction you're getting.

[plain mortar]

the angles arent a problem dude

when I'm running and jumping it works perfectly fine, the problem i'm having is the force not applying horizontally

[eternal needle]

🤷‍♂️ how much do you expect me to test, when the only thing i see from the code is math. Ive pointed out possible issues, i dont know why its a struggle for you to just show me the updated code.
If you're sure the direction is correct, then this is probably an issue with the rigidbody settings. Like friction that might be stopping it from moving

[plain mortar]

within that link is the entire code im using for the script

literally all of it

[eternal needle]

"literally" yet there is a debug in your screenshots, and no debug in your code.

if you want to be a pain to help, then ill simply step out. Ive pointed out 3 possible issues already yet i dont see you addressing any of it

[plain mortar]

do you really need to see what that is? Debug.Log("Angle: " + angle); how is that gonna change anything? cant you just infer based on the debug.log syntax?

you pointed out nothing to me

you told me it might be the problem with the mouse position, I told you the angles are correct from where the mouse is and the character position

I also told you it works fine when running, its an issue of force not being applied horizontally

you haven't tested out the code yet even thought I gave you all the code

[eternal needle]

Believe what you want then, when you feel like reading go back and re-read what i said. I pointed out different issues but you're fixated on one thing and clearly ignoring everything else. I cant be bothered to deal with sass. This is just a public place for help, so goodluck getting help in the future if you're an ass to everyone

[plain mortar]

If you cant be bothered to actually test the code I've given you I dont want your help. I help people with java stuff and since I'm pretty familar with it, the first thing I do is test the code...

if you tested the code you would've noticed that it has nothing to do with the angle, debug arc Im working on adding that, as far as the rigidbody issues I dont know what you want me to do with, I have not changed any settings for the RB, how would I act on you just telling me its an "rigid body issue"

YIKES

[eternal needle]

I did test, if you cant be bothered to get off your high horse then really no ones gonna help you 🙂. Infact i only noticed this from testing #💻┃code-beginner message

[plain mortar]

you clearly didn't test lol

[plain mortar]

"how much do you expect me to test, when the only thing i see from the code is math"

also if you did test, you would know its not an issue with the angles...

if you actually put Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition); in visual studio you would know there is no problem with it

dont tell me you've tested...

[eternal needle]

alright then, goodluck with your issue. Im out and thats a block cause you clearly cant get past your frustrations to even properly read what i wrote. Literally the 2nd word after "rigidbody settings" suggests a possible cause

[plain mortar]

again, how am i supposed to act on that?

thats like saying "theres an issue with your code"

[plain mortar]

if you tested you maybe would've saw a specific example and I could've done more research on that

I've shared ALL information I have

there is nothing more that I have

[eternal falcon]

lutaic was banned.

[real rock]

Pretty sure it was because of some fucky implicit conversion stuff at a glance anyways

For all they went on about how they tested and debugged it they converted something to a vector3 and then immediately implicitly to vector2

[languid spire]

All I see is a complete failure to debug the only 3 values that actually matter. But, hey, what do I know?

[burnt vapor]

Guess we will never know considering they would rather bash the help they retrieve 🤷‍♂️

[fickle plume]

It is usually something omitted overlooked. If someone wants to do a sanity check and go over the exact testing method, it is with the good reason.

Debugging remotely is hard

They’re not going places in real life if that’s how they treat an IT tech

Sometimes you just gotta ask questions because usually the real answer is no

[languid spire]

It's the same old, making assumptions and refusing to be shifted off them

[eternal needle]

im mostly sure it was friction, but there were other issues that i pointed out too

[languid spire]

yep, debugging the normalized vector, the force applied and the resulting velocity would have cleared up the problem in 5 seconds

[storm dove]

what does Vector2/3 do?

[languid spire]

it doesn't 'do' anything. It's how you use them that 'does' things

[storm dove]

what are they then?

[languid spire]

fundamentally they are structures which contain 2 or 3 float values

[vast vessel]

Hey guys!
Is there a reason why im getting null refrance eceptions in my build from my AI Locomotion script, but everything is fine inside of the editor?

[burnt vapor]

Maybe because an editor script modifies a state that is no longer modified in builds since these type of scripts are not included

[languid spire]

Script Execution Order. Check which scripts your AI Locomotion script relies on to run first

[vast vessel]

How is the execution order diffrent from in editor?
Does Awake run before Start or something like that?

I meant after

[languid spire]

Not that, but the sequences of Awake and Start amongst the scripts can/will change. So Awake and Start in one script should not depend on Awake or Start in another

you are ok to rely on Awake in one script/Start in another but not Awake in one script and Awake in another unless you specifically set the execution order

[vast vessel]

Aleight thanks!

[astral falcon]

You can still introduce your own methods and add them to the executionorder and change it to your needs, if you really need

https://docs.unity3d.com/Manual/class-MonoManager.html

[main anchor]

no i don't think so, but i dont really know how i can swap the rotation to the player model from the camera

[valid stone]

this is probably a stupid question but how do I create a square in code (unity c#)?

[wintry quarry]

Depends what you mean by a square

[valid stone]

a game object with the sprite of a square

[wintry quarry]

Make a prefab and Instantiate it

[tepid horizon]

im having a dumb nooby problem where i character cant rotate with my camera

[languid spire]

your null ref exception might have something to do with that. Fix it

[tepid horizon]

the problem is i cant diagnose it. you can see the script is definetly PlayerController and you can see that script and nothing is not filled.

[languid spire]

So what is line `161 of FirstPersonController?

[tepid horizon]

ohh didnt see in the error it reference the line

crosshairObject.gameObject.SetActive(false);

[languid spire]

so crosshairObject is null

[tepid horizon]

oml thanks that was a silly mistake that was meant to be // for later

[languid spire]

the error messages do not lie. Learn to actually read them

[tepid horizon]

ok another problem i double slashed everything to do with my crosshair and sprint bar. basically everything that was the problem that i would use later, but unity isnt reading the double slash and its acting as if it want double slashes. and i definetly did save the script so it wasnt that

[burnt vapor]

If it's commented out and you saved the file, it will be used as a comment. If this is not the case then you either commented out the wrong thing, have related code uncommented or you simply didn't save the file

[valid stone]

this has nothing to do with prefab but why does this not work?

[slate haven]

I want to spawn my cars faster but I can't somehow. The spawn rate (TimeTillNextSpawn) is already 0f. Also I have this function bool CheckForValidPosition() which makes a good amount of space between cars so they don't spawn on each other. Maybe this is the cause I can't spawn cars more faster as it rejects the position for spawning. Please do help me!!

CarSpawner script: https://pastecode.io/s/s8tkvn16

[burnt vapor]

What is the problem exactly? Cars do not spawn in general or after a certain amount of time passes?

I don't see an Instantiate method in this code, so how are they spawned to begin with? This is quite a bit of code

[slate haven]

They do spawn, but I can't make them spawn faster

[astral falcon]

Check your inspector for timeTillNextSpawn

[slate haven]

object pooling

[burnt vapor]

Ahh, I see

Did you verify op.SpawnFromPool is being called in general? Does this method even get reached?

[slate haven]

also the thing which is making them not spawn faster is most probably my function which makes a good amount of gap between them

[slate haven]

yes

[burnt vapor]

Oh, sorry. I misread, it does spawn

[keen dew]

timeTillNextSpawn = 1f;
yield return new WaitForSeconds(timeTillNextSpawn);

🤔

[slate haven]

cars do spawn

[burnt vapor]

Well, yes. That what Nitku mentions is the thing that stands out

You spawn the car and then hardcode wait a second

[slate haven]

i did it to 0 as well, but it doesnt spawn much faster

like yes it does

but not significantly

[burnt vapor]

You don't want the speed to increase, just spawn faster?

[slate haven]

like i have this traffic increase pickup, so I want whenever player picks that, cars shall spawn much faster every time

[slate haven]

yes

shall I share a gameplay video as well?

[astral falcon]

What happens if you move the coroutine content into the update methodfor now?

[burnt vapor]

I'm not sure how WaitForSeconds works but considering it is for seconds I would assume that 1 is the minimum

If you want to it be faster, perhaps use a different yield method

[slate haven]

like how

[burnt vapor]

For example, get the current time with Time.time, and then wait until a certain amount of time passed

Using yield null; skips a frame

Alternatively, use an actual Timer

[slate haven]

what happens when it skips a frame

[burnt vapor]

It will run the next frame

[slate haven]

and how do i use that timer to make the cars spawn faster, like very quickly

[astral falcon]

I still would try update() first to see, if your code can run faster at all

[keen dew]

WaitForSeconds does wait for fractional seconds and waiting for 0 seconds waits one frame. I'm assuming the problem is with CheckForValidPosition, you'll have to do some debugging

[slate haven]

as I told, that wont change anything as the thing which is causing my cars to spawn slow is the CHeckForValidPosition()

[slate haven]

yes thats what i was saying, what do i do with that

[astral falcon]

Ah, missed that part, sorry

[keen dew]

Increase the minSpawnDistance and see what happens

[slate haven]

u mean decrease right?

because when I decrease it, all the cars spawn on top of each other lol

[astral falcon]

I would use async calls and let each object create itself while starting the next one

[slate haven]

sorry, what is that?

[wintry quarry]

Explain what you mean by "doesn't work"?

[keen dew]

You'll have to tweak the values like spawn distance and radius and find the combination that works the way you want

[valid stone]

the gameobjects aren't squares

[wintry quarry]

What are they

[wintry quarry]

Looks like the sprite doesn't exist

sounds like you never made a sprite called "Square" in a resources folder

[slate haven]

so like trial and error?

[wintry quarry]

I really really strongly recommend just using a prefab instead of this

[keen dew]

That's how it goes

[astral falcon]

Look up https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task?view=net-8.0

[astral falcon]

Thats bad habit actually 😉

[slate haven]

[SerializeField] public float minSpawnDistance = 2f;
[SerializeField] public float radius = 1f;
[SerializeField] public float timeTillNextSpawn = 0f;

These are the default values, in which it doesnt even look as if the cars are spawning faster, so like how do i even tweak them to make spawn rate faster? like these are the lowest

[valid stone]

how do i use prefab for squares?

[keen dew]

This is essentially a game design issue, not a problem with syntax or logic

[astral falcon]

Dont tweak around until it might work. YOU should know, what your code is doing, not fortune or luck 😄

[wintry quarry]

Squares are not special.

Make a prefab that is how you want it to be

And Instantiate it

[slate haven]

i mean yes, but i know whats my code doing. I just dont know how do i make it better to achieve my goal

[keen dew]

but the radius is how far apart the cars spawn, if you increase that they'll (theoretically) spawn faster

[slate haven]

okay that sounds cool, let me tweak and try

[wintry quarry]

Read these links:

https://docs.unity3d.com/Manual/CreatingPrefabs.html
https://docs.unity3d.com/Manual/InstantiatingPrefabs.html

[valid stone]

where is this prefabs folder

[slate haven]

Lol i just realized that my code isnt changing theses values on the inspector, thats why it might not be changing

[valid stone]

I have "all prefabs" under favorites but I don't know where this prefabs folder is

[astral falcon]

... seriously?

[valid stone]

or is this a folder you have to create yourself?

gives false all the time

where i can be wrong

[wintry quarry]

There are no colliders in the path of the capsule cast

One note- You're using a 3D capsulecast. Make sure your game is not using 2D physics for example.

[sleek sage]

i fixed it but got another thing

where i am wrong at this code lines

im trying to make a simple jump

[slate haven]

what was the website where I can embed videos and share here?

[wintry quarry]

Wdym by "another thing"? You have to share what the problem is with the rest of us if you want help

[wintry quarry]

You can directly share MP4 videos here

[slender bridge]

he says he is trying to jump but that code is far off from anything relevant

[sleek sage]

my object just falls

[wintry quarry]

Well yeah this doesn't look like code that would jump at all

It slightly moves the position up for a single frame, that's it

[rare basin]

public List<UnityEvent<T>> unityEvents;

is there any way to serialize this prettier in Unity?

[wintry quarry]

You should be jumping via your Rigidbody, if you have one

[sleek sage]

isnt this how jumping works in games

[wintry quarry]

Turn your inspector off of debug mode

[wintry quarry]

No

[rare basin]

it's not in debug mode

[sleek sage]

i dont have rb

[wintry quarry]

Then you need to simulate velocity etc in your code

[rare basin]

List<UnityEvent<T>> the generic type is not good i guess

for serialization

[wintry quarry]

Hmm maybe

[astral falcon]

Custom editor?

[rare basin]

    public class ObjectEventActionSubscriber<T> : SerializedMonoBehaviour
    {
        public List<UnityEvent<T>> unityEvents;

        public EventActionObject eventAction;

        private void Awake()
        {
            eventAction.OnEventObj += InvokeAllEvents;
        }

        private void OnDestroy()
        {
            eventAction.OnEventObj -= InvokeAllEvents;
        }

        public void InvokeAllEvents(UnityEngine.Object value)
        {
            foreach (UnityEvent<T> unityEvent in unityEvents)
            {
                var converted = (T)Convert.ChangeType(value, typeof(T));
                unityEvent.Invoke(converted);
;            }
        }
    }

that's the whole class

maybe I could add where T : Object

would that help

[astral falcon]

why not go with object already then?

[rare basin]

because i want a reference directly

to what im passing via the event bus

[astral falcon]

Ah, got it

[rare basin]

public EventActionRaiserObject<MapSector> raiser;

can i write property drawer somehow

for the List of unity events<t>

[slate haven]

I try to change the values of spawnRate, but then the whole game lags and the existing cars just disappear after spawning which is kinda weird. Please help me this is happening when I decrease the minSpawnDistance or the radius.

CarSpawner Script: https://pastecode.io/s/f1u7up3j
Object Pooler: https://pastecode.io/s/66wq79uu

[astral falcon]

Looks like its pooling current ones to new positions?

[slate haven]

why would it?

[astral falcon]

You only have a x amount of pooled objects, right? when do you label them "free" to be used by your pooling system?

[slate haven]

yes

100 amount

so if i increase spawn rate

it has to reuse

oh man

what do i do now? Increase amount of pooled objects?

[astral falcon]

Remember when you said, you know what your code is doing? 😉 You yourself gotta keep track of what is active and what can be reused and so on. Either calculate a fixed number you can guarantee to not reach and use that as minimum objects or let it dnymically decide and wait for the next free object. really depends on your game design and how you determine the amount of cars being spawned, probably with a difficulty increase or what not

[rocky canyon]

i do the former

cuz laziness an' all

[slate haven]

at a time 14k cars are spawning lol

[rocky canyon]

what in the world are u doing where 100 is not enough?

[slate haven]

i mean i set it to 10

[astral falcon]

So still some code issues you gotta check against to avoid this spawning endlessly

[slate haven]

i fixed the lag and sudden disappearing of cars by setting the fixed amount from 10 to 100. Now I gotta tweak with the spawn rate so cars just dont appear on top of each other if i increase spawn rate

[astral falcon]

You could check for an amount of time if a new car is available, if not, fallback of creating one to keep your spawnrate constant. But there are many ways to achieve your game design

[slate haven]

yeah, understood, THanks!

[slate haven]

also, my game lags like hell when The cars are increased, what to do to optimize it? (I already have object pooling)

[astral falcon]

are you back to 100 cars or still 15k?

[slate haven]

3k cars spawning

i mean not spawning

but its using cars from 100 amount. I have 3 different car prefabs, i have set 100 to all 3 of them

[astral falcon]

that would be 300, not 3k

[slate haven]

yeah im sorry, thats 300 cars, but why is it lagging?

[astral falcon]

You are doing everyting on the mainthread right now. So could be your calculation, some checks on your positions. I would check the profiler what script takes the most time

[slate haven]

i have used profiler but How do i check what thing is causing the lag?

[rocky canyon]

u click on a spike..

scroll down, in the hierarchy

and see what methods are taking the longest

[ivory bobcat]

Maybe show where you're calling jump as well

[slate haven]

can u explain?

[astral falcon]

You click on cpu usage and down in details, set hierarchy and go through with the most ms time of your scripts appearing for example

[slate haven]

oh, okay i will do that now

[rocky canyon]

expand this..

and ur code will be shown inside it

[slate haven]

ah

[rocky canyon]

Editor loop is stuf Unity is doing for the Editor

PlayerLoop is whats going on in teh game (your code)

[slate haven]

got it

[swift crag]

all of the time is being spent in EditorLoop in this screenshot

[rocky canyon]

facts.. thats twentacles screenshot

[swift crag]

you pointed to PlayerLoop, but that's only spending 1.64ms

[rocky canyon]

ya im showing guy how to check his profiler..

he hasnt posted yet

[astral falcon]

It was just my project for explanation of the profiler 🙂

[swift crag]

oh!

[rocky canyon]

he's pooling soo its bound to be a little heavier on his

[swift crag]

🤦‍♀️

I misunderstood and thought you were helping twentacle

"well, duh, that's twentacle's screenshot..."

[rocky canyon]

twentacle doesnt need help 😄

[swift crag]

except with excessive garbage collection times, maybe 😛

[rocky canyon]

i do wonder what my player loops looks like

[swift crag]

you should add profiler markers!

[rocky canyon]

not too shabby 🙂

[swift crag]

they let you measure how much time is spent in specific regions

[astral falcon]

Blame it on polyspatialcore 😄

[swift crag]

(without slamming the Deep Profile button)

[swift crag]

900 bytes of garbage?!?

[rocky canyon]

is that alot?

[swift crag]

no

[rocky canyon]

oh ok 😅

i scared for a minute

[swift crag]

but you should make it zero anyway 😁

[rocky canyon]

impossible

im not that smart

[astral falcon]

Its not in your hands sometimes 😄

[swift crag]

my AI code currently generates hundreds of KB of garbage per planning cycle (every 0.25 seconds by default). i need to start memoizing some of these objects..

[rocky canyon]

how do u deal with the garbage?

[swift crag]

lots of objects that get re-created every time they're used and that don't actually store any mutable data

[rocky canyon]

do u manually flush it?

[swift crag]

you re-use objects instead of throwing them out, basically

pooling!

[rocky canyon]

yea, i get that.. but im askin for your setup..

[swift crag]

For example, I have an "Activity" class that represents an action you can perform

[rocky canyon]

are u intervening somehow

or just letting Unity take care of it

[slate haven]

wheres the player loop?

[swift crag]

for each possible action (say, the player opening the door), I can just create one Activity and re-use it

[rocky canyon]

change the dropdown to Hiearchy

[swift crag]

right now i don't

click on CPU Usage first

[swift crag]

you're focused on the Rendering row

[rocky canyon]

its my GUI redraw 👀

w/o that im netting 0

lmao

[swift crag]

oh yeah, and that's a fair place to create garbage

I don't think you can avoid it with IMGUI

[rocky canyon]

im using GUI stuff for debugging purposes

i like to have my debugs on screen

[swift crag]

and I don't try to optimize allocations for debug code anyway

My planning system uses pooling to minimize allocations, but the code that dumps the plans out to a file is allocation city

since that's not actually part of normal gamepaly

[rocky canyon]

do u have custom pooling or do u use unity's system?

[swift crag]

I'm using Unity's Pool classes

[rocky canyon]

ohh bad-ass

[swift crag]

Although this is just going to be a dictionary

you'd call that "memoization"

basically, before you compute f(a,b,c), you see if you've already computed f(a,b,c)

if you have, you return the value it produced last time

It's a bit scary to do it with reference types, since you have to make sure you aren't creating a weird conflict

[swift crag]

like, if I stored mutable data in Activity, I'd have to make sure that I didn't have two references to it that don't expect to be sharing the same object

[rocky canyon]

i got a question:

say, I want to spawn an object in a radius.. but i don't want to spawn in x distance from another spawned object..
i can say, if the number isn't valid reproduce another value... and that could happen indefinitely if im unlucky like that..
now i could say, if u dont find a valid number by z amount of loops then give up..

[swift crag]

that's called "rejection sampling"

[rocky canyon]

but.. giving up kinda lame.. is this the only way to deal with taht?

[swift crag]

note that for this situation, you can use Poisson disc sampling

[rocky canyon]

yea ive heard of this..

[swift crag]

it's designed to produce roughly uniform looking points where no two points are closed than a certain distance

[languid spire]

there is another option. fill an array with possible valid options and select from that array

[rocky canyon]

i mean, yea that could work..

[swift crag]

You could fill a space with Poisson disc sampling and then randomly choose points

[rocky canyon]

but the array would end up being huge.. if i really wanted a random feel to it

[swift crag]

(the sampling gradually fills in the space from a starting point, rather than placing down points in random positions)

[rocky canyon]

u saying if u spawn something on Index[p] then don't use p anymore?

[swift crag]

If you have a huge space, then you can just do rejection sampling

[languid spire]

np, as long as you can build it once and reuse it, memory is cheap

[swift crag]

It's very unlikely you'll actually have a problem if the density is low enough

randomized algorithms are remarkably predictable (:

[rocky canyon]

well some of my play areas are pretty small

and im still trying to achieve a random feel

but not much space to work w/ and unity random sucks

[swift crag]

you can also pick random points and then relax them

[rocky canyon]

whats relax them mean?

[swift crag]

unity's random number generator is fine; it generates random numbers

[swift crag]

If points are too close, you push them apart.

[rocky canyon]

ohhh ive never heard of that one

[slate haven]

i checked in playerloop, now?

[rocky canyon]

and unity random sucks*

*in my situation, working in small area's i get repeats often

nothing against it.. i'm not gonna write my own RNG for sure

[swift crag]

any random number generator that didn't cause overlaps would be a bad RNG

https://en.wikipedia.org/wiki/Clustering_illusion

[rocky canyon]

i'll look

[swift crag]

These dots have uniformly random positions

[swift crag]

are you getting a single laggy frame?

if so, you need to select it in the graph view

this looks fine: the playerloop is taking under 2ms

[slate haven]

not right now

[languid spire]

human brain doing what it does best, pattern matching

[slate haven]

yeah

[swift crag]

Poisson disk (not disc, oops) sampling produces distributions like this

[rocky canyon]

OHH

i know exactly what that is now

[swift crag]

You might also see it called "blue noise"

[rocky canyon]

yea yea..

ive seen someone do a study on it

i jsut didnt know what it was called

[swift crag]

See if you can catch the game being laggy

you can hit ctrl-shift-p to pause

[rocky canyon]

pro-tip ^

i still cant remember that dang hotkey 🤣

[swift crag]

i keep forgetting the "step one frame" shortcut

[rocky canyon]

isnt it >?

[swift crag]

ah, it's cmd-option-p on my mac

so probably ctrl-alt-p

[swift crag]

not in Unity, at least

[rocky canyon]

this is exactly what i need to learn

[swift crag]

I use something I copied from a blog post. The finest source.

[neat scarab]

hey everyone! currenlty trying my best to code a simple fishing game :) just wanted to know if anyone knows how to make the rotated fish dissapear once he hits the max he can go (the bottom of the boat)

and the score must go to 1, which i think its fairly easy to code...

[burnt vapor]

Easiest way is to determine the y value of the bottom of the screen and check if the fish doesn't exceed that

[rocky canyon]

http://gregschlom.com/devlog/2014/06/29/Poisson-disc-sampling-Unity.html
this it?

[lethal bolt]

Do something like if transform.position.y > 100 I think

[rocky canyon]

since its 2d u can easily check if its position.y is > than ur boats bottom

[swift crag]

You can compare the position of the fish to the position of the boat

[swift crag]

so this, but with the boat's position on the right side

[rocky canyon]

3-piece

[neat scarab]

can you explain a lil better? sorry if its asking too much

im really new at this

[rocky canyon]

track ur fish's y property of its transform... fish.transform.y

[burnt vapor]

Do you know how to check the fish position using logging?

Try finding out what its y value is when it's low enough

https://unity.huh.how/debugging/logging/how-to

[rocky canyon]

just drag an empty gameobject to the bottom of ur boat.. and check the y position

that y position will be useful to test if ur fish is above it

soo if its y position is > than the y position u desire

[neat scarab]

the empty gameobject will make him disappear?

[rocky canyon]

noo.. lol i meant to use it to find out what the bottom y position of ur boat is

[swift crag]

No. An empty game object is a game object with nothing attached to it.

[rocky canyon]

and then delete it cuz its just a tool

[swift crag]

They can be useful for creating a "reference point"

if (fish.transform.y > catchPoint.transform.y) {
  // catch the fish
}

instead of having to do something like this

if (fish.transform.y > boat.transform.y - 0.5f) {

}

where you figure out that value through trial and error

[burnt vapor]

Not really

You should probably just specify a base y value and store that in a serialized value, then you can just modify it in the inspector

Both work

[rocky canyon]

i was meaning this.. like if i wanted to find out what the bottom of my potion was..

i can use an empty gameobject to position right below it.. and know what the Y is.

[swift crag]

yes, a field would be smarter :p

you'd still have to trial-and-error it if you don't directly measure the distance, though

[burnt vapor]

But we currently have three answers concurrently happening here, I suppose we should stick to one since it's already confusing enough

[rocky canyon]

we all agree on this ^

[neat scarab]

okay I already know the position of the y axis... how can i make the fish dissapear when he colides with the boat? thats what im having problems atttt

bc he already has a limit

[burnt vapor]

Your messages suggested the object was merely to check the y value through the inspector, so it can be added to the code and then removed. I agree the object is best to use as reference though

[burnt vapor]

Easiest way is to call Destroy on it.

The gameobject will be removed altogether

[neat scarab]

ooooo okay going to look into it!

[neat scarab]

and when he collides with the limit, he will be gone and the counter will be up one, so, its gonna be a if variable right

[rocky canyon]

public class IsAboveY : MonoBehaviour
{
    public float YLimit;
    void Update()
    {
        if(transform.position.y > YLimit)
        {
            Destroy(gameObject);
        }
    }
}```

[final kestrel]

does newtonsoft serializer serialize dictionaries?

[burnt vapor]

Yes.

[final kestrel]

Thank you

[burnt vapor]

It serialized basically anything. Only crappy JsonUtility has trouble with everything

[neat scarab]

will update you soon

!!

tyy

[final kestrel]

oh I have trouble serializing vectors. Is it on my end?

Like I read that I have to break it down to pieces

[burnt vapor]

Newtonsoft has trouble with them because the implementation of Unity types are very poorly done

It basically serializes irrelevant data

[final kestrel]

it still is the preferred way to use newtonsoft's right?

[burnt vapor]

Yes, you can work around it

[final kestrel]

All right thanks a lot.

[burnt vapor]

I think this repo has good information about it https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters

[swift crag]

One catch: JSON object names are strings.

They can't be arbitrary json values

[burnt vapor]

If Unity added a simple ignore attribute to some of its properties then these things would not have been needed, but alas

[swift crag]

So if you have a Dictionary<SomeClass, AnotherClass>, then SomeClass gets turned into a string

you can't have something wild like

{
  [1, 2, 3]: "wow!"
}

in my case, my dictionary keys could be looked up via a GUID, so I made Json.NET write out the key's GUID when serializing

i think i wound up not serializing dictionaries at all, though, and just writing out lists of keys and values

[final kestrel]

Where can I learn more about guids?

[swift crag]

a GUID is just a 128-bit identifier, a lot like an int (32 bits) or a long (64 bits)

[final kestrel]

the stuff im watching is using ints instead of guids I believe

[swift crag]

I'm using GUIDs because these are all assets, so I just copy unity's asset GUID over!

https://bronsonzgeb.com/index.php/2021/09/11/the-scriptable-object-asset-registry-pattern/

[final kestrel]

Ah so all assets have their own guids all right

[final kestrel]

wohh thanks!

[swift crag]

this is the pattern i'm using

along with a JsonConverter https://gdl.space/wesojoyedi.cpp

IdentifiableRegistry gives you an object when you give it a GUID. You'd have to implement that yourself (e.g. by loading a bunch of assets from a Resources folder during startup)

[final kestrel]

Nice I'll study the links you sent! Thanks again.

[rocky canyon]

hey fen,

[swift crag]

my boolean settings are serialized like this

i should at least use base64...

6 bits per character instead of 4!

[rocky canyon]

fancy

[swift crag]

neat (:

is it trying to spawn once per frame? i see that it slows down as it goes on

(or maybe a fixed number of times per frame)

[rocky canyon]

oof, idk i found the best repo i could find

there a few assets on the store but their paid

[lethal bolt]

if i animate an model with only the basic like Head, torso, stomache, etc and put on an animation that moves the jaw, and finger. Will it still work?

[swift crag]

if all of these are Humanoid animations, then Unity will just ignore the parts of the animation that your model's avatar doesn't support

[lethal bolt]

Okay

[rocky canyon]

Every Frame yes

[rich adder]

wdym. how did you even put this together then?
rotate the player objct, you have a reference to player don't you?

[main anchor]

yea im pretty sure i have a reference to player, the rotation seemed to work fine just a few days ago and the player was rotating too, i don’t really know what broke it though

[summer shard]

the rotation is "stuttering", how can i fix that

private void HandleMouse()
{
    float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
    float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

    transform.Rotate(Vector3.up * mouseX);

    turn -= mouseY;
    turn = Mathf.Clamp(turn, -85, 85);
    cameraHolder.eulerAngles = new Vector3(turn, cameraHolder.eulerAngles.y, cameraHolder.eulerAngles.z);
}

private void Update()
{
    HandleMouse();
}

[rich adder]

* Time.deltaTime you should not multiply Mouse inputs by deltaTime. Ever. it already is timeframe independent

[summer shard]

without it, it's still stuttering

[rich adder]

regardless you should not have it

[swift crag]

did you actually make the change and test it again?

[summer shard]

i've tested it before

[swift crag]

fix it and make sure you're still having the issue

[summer shard]

i do

[swift crag]

if it persists: is it always stuttering, or is it only doing that while you're also moving around?

[summer shard]

always

[swift crag]

Is there a rigidbody on your player object?

[summer shard]

yea

[swift crag]

you should not be directly modifying the transform, then

especially if Interpolate is enabled on the rigidbody

the rigidbody will overwrite the position and rotation every frame

[wintry quarry]

Shouldn't be. Remove it, save it, test again, and make sure you reduce sensitivity

[rich adder]

You're rotating in Update while rigidbody processes movement in FixeUpdate

[wintry quarry]

ah yeah that's your problem too

rotate the Rigidbody instead

rb.rotation *= Quaternion.Euler(0, mouseX, 0);

[swift crag]

note that this means that the camera will only yaw 50 times per second

if you have Interpolate enabled, this will get smoothed out, but it'll also get a tiny bit of delay

[wintry quarry]

nah this one can be done in Update

[swift crag]

Setting the position or rotation of a rigidbody does nothing until the next physics update.

Changing the rotation of a Rigidbody using Rigidbody.rotation updates the Transform after the next physics simulation step.

[wintry quarry]

right but - believe it or not this works

don't ask me why

[swift crag]

well, sure, it works
