But choosing which direction to travel and when is complicated

unless you were able to simplify it in some way by placing a constraint on the system (like for example, nodes will only be directly adjacent to each other in cardinal directions)

[swift falcon]

what couldve caused this distortion in cosine

[regal grove]

mhmhm yea I wanted to use raycasts to see which tiles the pawn can move to

[warm shadow]

So i have this code that is suppose give in index number out but it always gives 0. Here is the code:

private Color GetSkinColor()
    {
        int colorIndex;

        int numberOfUnlockedTools = toolManagers.Where(tool => tool.Value.isBought == true).Count();

        colorIndex = Mathf.FloorToInt((numberOfColors / numberOfTools) * numberOfUnlockedTools);
        print("colorIndex: " + colorIndex + " = (" + numberOfColors + " / " + numberOfTools + ") * " + numberOfUnlockedTools);

        return colorSpectrum[colorIndex];
    }

And here is the print:
does anybody know what it is I'm missing

[leaden ice]

Integer division

25/38 is 0

[warm shadow]

ohhh, i see, thanks

[twilit hamlet]

How do I assign a value to a variable only if its undeclared?

[leaden solstice]

What do you mean "undeclared"
You cannot assign to something that is undeclared

[twilit hamlet]

sorry, I mean not assigned a value.

It's declared just hasn't been assigned anything

[leaden ice]

For float you can't really tell that

You'd have to use a nullable

[neat lagoon]

value types are not null when unassigned, they are their default value

[twilit hamlet]

really? that seems weird

[leaden solstice]

That kind of condition is not supported as the compiler cannot know where it has been assigned

[neat lagoon]

for example, by default, floats are 0

[leaden ice]

Why is it weird

They're basically primitives they can't be null

You could use a nullable if you want

[twilit hamlet]

ah ok, but theres no way to tell if it is default 0 vs set to 0?

[swift falcon]

Anyone know what couldve caused it?
transform.position += transform.right * Mathf.Cos((Time.time - startTime) * projectileFrequency) * projectileAltitude;
is what i have
should be fine but for some reason there is some weird offset

[leaden ice]

float? myNullableFloat;

[leaden ice]

Shouldn't do this additive thing

[leaden solstice]

Nullable or use flag like bool isMyFloatSet

[neat lagoon]

no

[swift falcon]

oh

hmmm

[leaden solstice]

Can you show more context

[twilit hamlet]

what is the default value of that then?

[leaden solstice]

null

[swift falcon]

oh right. start time is simply time.time in Awake function

[twilit hamlet]

null? and does it act like a float other wise

[swift falcon]

so the bullet always starts moving from the same start

lemme make a gif

[leaden ice]

more or less...
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/nullable-value-types

[twilit hamlet]

That's so cool! I always wondered what nullable ment

[twilit hamlet]

Ah shoot, so its not that easy. ofc it isn't lol.

[leaden ice]

You shouldn't do it like this.
You should do:

Vector3 startPos;
float time = 0;

void Start() {
  startPos = transform.position;
}

void Update() {
  time += Time.deltaTime;
  Vector3 currentPos = transform.position;
  currentPos.x += Time.deltaTime;
  currentPos.y = startPos.y + (Mathf.Cos(time * projectileFrequency) * projectileAltitude);
  transform.position = currentPos;
}```

trying to additively do this won't be consistent

[leaden solstice]

Yeah you should make it relative to initial position

[twilit hamlet]

I can cast it, but its a little annoying

[leaden solstice]

Not accumulation

[leaden ice]

just need a .Value

[swift falcon]

oh, that makes a lot of sense actually

thank you so much, ima take my time and try to understand it

[twilit hamlet]

What would .Value return if it was null though?

[leaden solstice]

NullReferenceException

[simple egret]

Note that this, or accessing .Value if the nullable is null will throw an exception. If you need to pass in a default value if the nullable is null, you can use this handy syntax: nullable ?? defaultValueHere

[leaden ice]

Straight from the docs

[simple egret]

?? returns the thing on the right, if what's on the left is null.

[leaden solstice]

Ah it's InvalidOpertionException 😄

[twilit hamlet]

Jesus, I thought this was a quick and easy question, why do floats gotta be so weird with nulls

[twilit hamlet]

ok thats really handy to know tho

[leaden ice]

it's a very quick and easy question

you're overcomplicating it tbh

[dusk rain]

I have a problem, I'm getting a null reference on this line https://i.imgur.com/JQO4ZsX.png, and its the Gamecontrols part of the code, that gives a null reference, but its not doing that for a different script with he same line of code.

[twilit hamlet]

are you kidding me

[leaden solstice]

Remove .Value there

[simple egret]

Well don't access .Value in this case

[leaden ice]

Which line

[dusk rain]

the start of the If statement

[twilit hamlet]

what is the .Value returning then if not a float?

[simple egret]

Nothing, you get an error: InvalidOperationException

[leaden ice]

Gamecontrols is null most likely

you'd have to show where you assigned it

[dusk rain]

https://i.imgur.com/hccB0iJ.png

[twilit hamlet]

Ok thanks, I don't even need null safety here cuz it will be set in Awake() but that's super useful to know thanks.

[leaden ice]

that's not assigning it

that's just declaring it

[dusk rain]

The code that isnt working in this script, is working in other scripts though, so i'm not sure why this script cant find my inputsystem

[leaden ice]

you aren't assigning it in this script

you are in the others

[dusk rain]

oh ok

[leaden ice]

Assignment needs the = operator.

[dusk rain]

This error only happens, in my build, not in the editor.

[leaden ice]

Why don't you just show where you're assigning it

so we can rule that out as the problem. So far I can only assume you just never assigned it.

[dusk rain]

https://i.imgur.com/W1mzg5h.png

[leaden ice]

What is InputManager.inputActions and where is that assigned

[swift falcon]

oh right, i remember the issue i ran into about when using relative to initial position, like X and Y is fixed in the world, but is there some method i dont know about that could kinda make it relative to a certain vector

something along these lines

dont know how to formulate the question to google it haha

[dusk rain]

input actions, is the name of my asset

[leaden ice]

ok but

that field

it's a static field?

How and when is it assigned?

How do you know that assignment is happening before this code runs?

proobably just a script execution order issue

[dusk rain]

https://i.imgur.com/BDwOpVn.png

[leaden ice]

Go to the InputManager script

[leaden solstice]

You can still use transform.right and transform.up to represent local XY axis in world space

[leaden ice]

show how and where inputActions is assigned

[swift falcon]

oh alright thank you

[dusk rain]

https://hastebin.com/gokufufula.csharp

[leaden ice]

rigth so

as I said

it's just a script execution order issue

   private void Awake()
    {
        if (inputActions == null)
            inputActions = new GameControls();
    }```

This is running after your other code

so it's still null when the other code runs

[dusk rain]

oh ok

[leaden ice]

Recommend just getting rid of is code entirely. Just use a lazy property e.g. private GameControls Gamecontrols => InputManager.inputActions; delete the rest

[dusk rain]

So delete the Onenable and Ondisable code and just put ^ this code?

[dusk rain]

I think its working

[swift falcon]

o almost got it

just projectile stands in place now lol, but at least the sine is right

[dusk rain]

Yes it's working thank you.

[swift falcon]

oh right, because i used rigidbody force as forward movement

when changing transform.position directly it doesnt quite work now

[trim spoke]

hey guys , i can use some help breaking my head over this for hours. my raycast drops my game from 60 to 30fps or worse. what could be the cause if anyone stumbled upon something similar?

[warm shadow]

I have a problem, so I have some things you can unlock, and some of them makes a popup show. The current way I'm doing it is every unlock have a variable that is isBought which become true when you buy it, the the popup system runs every frame and looks if the specific unlock is unlocked, and if it is it shows the popup.
The issue is now it of course keep showing even after I close it, as it is still bought. How do I fix this?
I cant change isBought because I use it in other places…

[trim spoke]

link the closing button of the popup to a function that sets the popup inactive and sets the isbought false

[proper oyster]

how many ms does that take up?
have you tested that in a build?

[trim spoke]

if(item is bought) => popup.setactive

than make the button linked to a function in the same screen that has a function like
popup.setactive(false)

you dont even need the variable for that

[trim spoke]

about 3.4ms

[warm shadow]

ahh, ill try that

[trim spoke]

mind you im running the profiler on a pc for a game meant for android. on the phone this raycast is so bad it makes it go BURRR

[proper oyster]

for 60 fps each frame is 16.7 ms
and for 30 its 33.3
so your 3.4 ms is probably not the cause to drop from 60 to 30

[trim spoke]

its exponential. the game allows for creating a bigger level. the bigger it is the harder this ray sunks the performance

[past pier]

Hey Guys,

I'm desperate for anwsers and apparently equally incompetent.
What on earth is causing GC allocation in this code:

public static bool IsConstructionPiece(this Piece piece) => IsType(piece, snapNodes => snapNodes.Count != 0, Type.CONSTRUCTION);

Calling:

        private static bool IsType(this Piece piece, Func<List<Vector3>, bool> isType, Enum type)
        {
            if (isType.Invoke(primarySNs))
            {
                //Debug.Log($"Piece '{piece.m_name}' { piece.transform.position} IS a {type} piece");
                return true;
            }
            else
            {
                //Debug.Log($"Piece '{piece.m_name}' { piece.transform.position} IS NOT a {type} piece");
                return false;
            }
        }

(yes - you are correct - the commented out sections cause the Enum type parameter not do do anything)
while primarySNs refers to a simple collection variable, and Type.CONSTRUCTION is an enum value

I have a lot of these "IsSomethingPiece" calls -> calling IsType under the hood. And all of them allocate quite a bit of trash.
But more importantly than improving the performance I would like to simply understand... why does this allocate?

Is this some wierd-ass clojure magic due to me dragging in a constant enum value? Is this due to extension methods... somehow? Is it the work of the devil?

[proper oyster]

Graphics raycaster should only care about the UI

so very complex ui you have?

[trim spoke]

do you have experience with maxSDK? could the banner cause something like that?

[twilit hamlet]

I don't understand, the first one works fine but the second one tells me that using new on a MonoBehaviour class is not allowed. What's the Difference here? I just want to store data but im not allowed to make a new object to hold it?

[trim spoke]

there is alot of UI but they all are inactive during play

[proper oyster]

i have not
but if that a possible cause that should be easy to test

[proper oyster]

inactive as in the Canvas is not active?

[trim spoke]

yes. during play all canvases are set inactive. only simple 2D sprite objects are rendered

[simple egret]

You cannot use new on MonoBehaviours because that would mean creating one that isn't attached to a Game Object.
You can use new on PopList because it's not a MonoBehaviour

[proper oyster]

so no graphics raycaster should be active at that time

[trim spoke]

thank you for clarifying only UI can cause it. it might be the ad banner causing it

[twilit hamlet]

PopList is a MonoBehaviour and so is Bubble but making a new Bubble doesn't error

[simple egret]

Then Unity isn't picking it up

Either way you should never use new on anything that derives from MonoBehaviour

[twilit hamlet]

oh shot really? thats like all my code

[simple egret]

If it's not meant to be attached to a Game Object directly, don't inherit from MB

[twilit hamlet]

then it tells me this

[simple egret]

Yeah that's a result of using new on MBs

Or trying to attach a script that isn't a MB, onto a Game Object

[twilit hamlet]

No that only happens when I remove the : MonoBehaviour

[simple egret]

Yeah because now it cannot be on a game object anymore

If it just stores data, make a plain class

[twilit hamlet]

Then how would it execute if its not on an object?

Oh cuz its not mono

[simple egret]

It wouldn't execute yeah

You would do stuff with it, from other scripts that are MBs

[twilit hamlet]

Erg so I have to decide between a data structure and a Unity Runtime structure

I want an encompassing objects to store all its children in a list to save

omgosh, this linking between class objects and monobehavior objects is making my head hurt

[swift falcon]

@leaden solstice @leaden ice just wanted to thank you! managed to figure out how it works and make it work as well

[split furnace]

Hi. I'm trying to make a zip line the player and the AI can go in and out of. problem I run into is that the AI can go in but they can't get out. I tried measuring vector3.distance for the line to let go once the AI reaches point but no go.

any suggestions?

[timber snow]

hi guyzzz!!! how do i read how deep i am i to a collider O_O

[coral hornet]

how should i logically handle a character system

i want 4 different chooseable characters or classes, each with heavily varied gameplay

and im not sure how i should handle everything from the playermodels to the code that controls them

should i try to set up a base character controller that can use a public variable to determine what class it is controlling? should i store each playermodel indevidually or use a base playermodel and try to tweak it to fit the appearance i want for each class? should i have an items system to determine which item each character will start with or should i hard code it into the character controller considering that you wont be aquiring any more items?

[loud portal]

why doesnt the Mathf.Clamp do anything

[somber nacelle]

clamping the value doesn't mean anything if you aren't using that value to assign a specific rotation. all you are doing with that value is putting it in a Vector3 then using that vector's magnitude to rotate the object.
you should search "clamp camera" in this discord to find examples of how to correctly clamp the rotation

and don't crosspost

[loud portal]

when i search clamp camera it just comes up with people having hte same issue

[somber nacelle]

yes well you need to go back further and click examples

[indigo drift]

I'm currently using JSON.net but when i use jsonconvert.serializeObject I get a self-referencing loop error. Strangley this only happens when the class contains a vector2 variable... how do I fix it?

[leaden solstice]

https://docs.unity3d.com/ScriptReference/Physics.ComputePenetration.html

[twilit hamlet]

Hey quick question, is JsonUtility.ToJson() recursive? meaning if i have a gameobject with a list of gameobjects with lists, will this turn all of that into one json or do I need to manually pass up json data?

[zinc parrot]

why are index buffers not available in builds for meshes that dont have read/write enabled?

[polar marten]

like in a speculative sense or how can this be worked around?

[zinc parrot]

yes

[polar marten]

i think it has something to do with the graphics apis

and read/write really means whether or not a unity object is given to you representing the graphics resource

because in order to make that work, it has to do some kind of synchronization step that is potentially slow

[zinc parrot]

so wait why are they available in editor but not in builds?

[river lynx]

i have a script called score on 2 game objects how can i do that a variable has the same values?

[twilit hamlet]

I'm not 100% sure what you're asking but from what I guess I think you need static variables

[dusk rain]

Do you mean, making two floats match?

[river lynx]

i have a score display that shows my score. when i die i have another score display but it says 0

[twilit hamlet]

Just get the score from whatever is storing it, or am I not understanding

[twilit hamlet]

Are you saying you have 2 prefabs that need to share the same float, if so then make it a static float that gets updated

[river lynx]

yes that probably i just didnt want to make a new script for only one purpuse

[polar marten]

it would be a bug when those are different. however not necessarily a unity bug

it may appear to be the same mesh in editor

not 100% sure

[river lynx]

how

[polar marten]

when i run into issues like these it's never "because the editor is using the single threaded graphics device and player builds are multi-threaded / native jobs"

it's very very rarely "because the editor is dx11 and the device is opengles 3"

[twilit hamlet]

public class PlayerHealth : MonoBehaviour
{
    public static float health=100;
}

[polar marten]

index buffers sound too normal for that to be the issue

[zinc parrot]

hmmmm

[polar marten]

you can make sure your device and editor graphics apis are exactly th esame

[twilit hamlet]

a static variable is one that is shared among the class. So its like a globaly shared value, exectly for what you are trying to do

[polar marten]

including unchecking multithreading

which will worsen performance possibly significantly

[zinc parrot]

again, if I make the mesh read/writeable in editor and build, the index buffer is available
if I dont make it read/writeable its not available
im running dx12

[zinc parrot]

how?

[valid minnow]

why am i getting an error here?

above the else

[polar marten]

what device is it? i suppose just eyeball it

you'll bea blet o see

the windows editor supports opengles3

[valid minnow]

oh i fixed it, it was the semi colon on the if statement

[zinc parrot]

device?
3080 mobile?

[polar marten]

hmm

[river lynx]

now it messed up this csharp scoremanager.GetComponent<score>().score_count++

[polar marten]

no meant GraphicsDevice as in the graphics api

which yes it sounds like it's the same

[zinc parrot]

ahhh

[polar marten]

i think its' some other bug and this is a red herring

[zinc parrot]

unity thing or is it something in windows

[twilit hamlet]

if you just use a static variable then all you have to do is score_count++; Are they the same class? if so because the variable is static, they are linked. So when you update it on one, it gets updated universally

[river lynx]

different class

Static member 'member' cannot be accessed with an instance reference; qualify it with a type name instead

[twilit hamlet]

ah, then you might want to make the score manager a static class so that you can just do scoremanager.scorecount

[zinc parrot]

Graphic api is dx12

[twilit hamlet]

if you're not familiar with static classes/variables then I would recommend you read up on that. They are useful

[river lynx]

also do you mean static score class? thats the class name with the variable. score_manager is just a "container"so im told

[polar marten]

are you on 2022.2?

if not switch to dx11

[twilit hamlet]

sorry yes, you can just do score_manager.score or whatever because the class is available and you are accessing the class variable. Here's unity's guide, but they're pretty simple: https://learn.unity.com/tutorial/statics-l#5c8920e7edbc2a0d28f4833c

[twilit hamlet]

They give you an example on that first slide there

[river lynx]

oh no i have a ton of errors

its ok ill try the non static method first

[zinc parrot]

2021
I need the UAV count of dx12 for other shaders

but the error is on the CPU side

saying that the index buffer is null

[polar marten]

try dx11

dx12 is pretty buggy until 2022.2

[zinc parrot]

I... cant run my project on dx11

[mossy oriole]

Quick question, is it better to use a timer variable and subtract from it time.deltaTime to wait for a certain amount of time or is it more performant/simple to use corroutines?

[leaden ice]

It depends

[polar marten]

have you tried upgrading

[zinc parrot]

I have not, the thing I am making is for others to use

[leaden ice]

If this timer is not going all the time, a coroutine might be better to avoid having an Update.
But coroutines have their own costs - like garbage collection etc.
If the timer is going all the time Update is both simpler and cheaper

[mossy oriole]

Hmmm ok could you give an example

Like for a jump pressed buffer it would be best to use update rigth?

[leaden ice]

probably

[mossy oriole]

And couroutines for something like a loading screen that works similarly to the time-line package and that needs to be called just once?

[river lynx]

if this is my movement code
GetComponent<Rigidbody2D>().AddForce(transform.up * jumpForce);
why do i get a boost if i colide with 2 things it jumps higher (edited)

when colliding with platform

[versed marsh]

you die

[swift falcon]

Because it adds a force twice

[river lynx]

How can i fix? Should i always set force to 0 before applying the new one?

[swift falcon]

You can try

I dont really know how to check if its colliding with 2 objs

[river lynx]

Okay

And also how can I duplicate a game object through code? (A different game object not the one with the script) I’m trying to make a self generating level

My idea was to duplicate a platform every few meters and have a random X level in a range idk if it would work

[frosty moon]

GameObject newObj = Instaniate(oldObj, newPos, Quaternion.identity)

[river lynx]

Thanks now can you please explain what each word is? I’m a beginner sorry

[quartz folio]

Probably should have asked this in #💻┃code-beginner then

But you can use the docs to look up what Instantiate does, or what Quaternion.identity is

[river lynx]

Okay my bad

[upper adder]

I have a strange issue with the vertical rotation of my 2D character. I am using Unity's new Network for GameObject system. For example, when I flip my character on the X axis in my client, look how it acts on the host's screen. It flips like a sheet of paper, a bit like Paper Mario. It only does this when the Interpolate option is checked. I am having a bit of trouble understanding what to do to fix the problem. I have made a little video for better understanding: https://www.youtube.com/watch?v=xZeNciB7zfo

[neat lagoon]

This is a limitation of the interpolation. You are better off syncing a bool for "isFlipped" and applying it to the spriterenderer in your own code

Opposed to syncing the scale automatically

[upper adder]

@neat lagoon, so it's better to turn off synching of ScaleX ?

[neat lagoon]

Yes

[upper adder]

Okay I understand, thanks for the fast reply, I'll try that! 🙂

[gusty willow]

Anyone know what would be the preferred way to make a combat log/chat would be?
I'm wanting to use TextMeshPro so I can include symbols, and would ideally like it in a standard scrollable log
But as more text gets added it causes framerate spikes (my actual framerate is ~800, but adding text can take it down to ~8 for a few milliseconds). This is definitely noticable as it freezes the whole game (I can't thread off TMP)

I have seen some mention of this being down to TMP resizing and that it should be fixed (back in 2018), but other than that I can't see what a likely cause may be. Does anyone know of a good TMP chat/log tutorial? It feels like it would be a pretty common thing for a game

[cosmic rain]

Did you try profiling? I assume you instantiate a new TMP for each line? Try using one component for the whole log.

[gusty willow]

I'm using one component. I have turned on profiling, but honestly I am not familiar enough with it to know how to track anything specific

like, it happens for roughly half a second every 10 seconds

(Half a second is generous, more like 100ms)

I was going to try multiple components, but the replies on stackoverly make me hesitant to try otherwise, though I can't imagine a text variable gaining more and more lines would do well long term?

(speaking on the current one-component setup)

[cosmic rain]

See the frame graph. Identify spikes. Select a frame with a spike. Check the hierarchy view sorted by CPU time. Expand the most time consuming branch.

[cosmic rain]

I'd suggest to use the profiler to figure out the cause first before attempting any fixes

[gusty willow]

Apologies, as I said, I'm not familiar with this at all really. DO you mean the frame debugger, or the CPU usage frame-by-frame in the profiler itself?

[cosmic rain]

The CPU profiler.
If you're not familiar with it, now is a good opportunity to get familiar.

[gusty willow]

Yeah, I was trying, I feel like I do get stuck on the simplest points tho. Like, how to go back frames
It says I captured 20k frames, but I can only see the latest ~300

[cosmic rain]

Yeah, you can only see the data for the last several hundred frames. Captured frames is simply to get an idea on how long the profiler was on.

You can increase the max kept frames in the editor preferences.

[gusty willow]

I went with just spurting a lot more logs to make it easier to capture

[cosmic rain]

Garbage collection.

[gusty willow]

And one with actual column names... 😛

[cosmic rain]

You allocate 2.7 mb every frame😱

That's crazy kinda

[gusty willow]

Yeah, it kinda is. I have no idea where it comes from though

[twilit hamlet]

Hey just want to check, is the GetComponent<T>() a read only? or can I use a JsonOverride to set all values at once.

[gusty willow]

the scene has.. like, 3 spheres in it and the chat

[cosmic rain]

Wdym by read only? It returns a reference to the actual component, so you can access it's field, properties and methods and write to them if they allow it.

[cosmic rain]

Well it's coming from the TMP. Can you take a screenshot of the TMP text inspector?

[twilit hamlet]

So are you able to do thing.GetComponent<thing>() = newComponentThing

[cosmic rain]

No. That you can't do. Not just with component, but in C# in general.

[twilit hamlet]

wait, i just realized how stupid that is since its a function

my b

[cosmic rain]

Or any language that I know...

[twilit hamlet]

idk why I was thinking about it like a clas

[gusty willow]

I mean, the obvious answer is... it's a good chunk of text and most of it gets masked off, but.. it's one component getting assigned all the logs

[cosmic rain]

Aah. I bet it's the hypertext tags. Tmp is parsing the whole string and processing them, creating a lot of garbage in the process.

In this case splitting it into several components is probably the best option.

[gusty willow]

Ohh, not what I was considering at all then xD

[cosmic rain]

One for each line. And you can use a pool of text objects.

[gusty willow]

So have a list of text and push them into a limited set of components?

[cosmic rain]

Correction: when I said "split into several components" I actually mean "split into several objects". I think that was obvious, but just in case.

[cosmic rain]

Yep.

[gusty willow]

like a list of 20k lines, but only 20 actual components being assigned the text?

based on scroll*

[cosmic rain]

Yep.

[gusty willow]

I'll give it a go, thanks a lot for that

Any advice for a more.. customised scroll bar?

[cosmic rain]

Customized in what way?

[gusty willow]

In that if I have a fixed 20 components, it won't have an actual relative scroll, right?

I'll just be cycling 20 objects

[cosmic rain]

Aah

[gusty willow]

Or am I getting this wrong?

[cosmic rain]

Indeed. That would be a problem.

You'll need to customize the scroll bar for that, you're right.
I'd start with researching how the normal scrollbars works and figuring out if you can actually adjust it to your needs via code or you'll need to code it from scratch.

[gusty willow]

Cheers for that. Also, is there a way to run the profiler on a build game? I'll look it up if it's not a simple answer

but I figure I may as well check what it does with an actual build for GC

[twilit hamlet]

oh hey @cosmic rain , by the way remember when we couldn't get Unity to work? well I submitted a ticket and after 2 weeks of them not replying I opened unity to keep troubleshooting and it just worked. not a single error. not a single project that wouldn't run. I thought they put out a patch or something but then they got back to me and offered a new binary to try but I told them that it magically fixed itself.

[cosmic rain]

It's possible. The simplest way would be to build a development build and connect your editor profiler to the build.

[gusty willow]

Thank you again, Really appreciate your time on this. It might seem simple to you, but I was banging my head over it 😛

[cosmic rain]

Hmm... Then it was probably something with your environment. Maybe a sneaky windows update fixed it or something.

[twilit hamlet]

yah idk cuz i didn't touch my pc for 2 weeks

[orchid bane]

If I try to stop my coroutine does the parameter matter? Does it have to be the same as it was when I started it?

[cosmic rain]

You don't need parameters to stop a coroutine. If you do, then you're doing it wrong.

[orchid bane]

Thanks

[cosmic rain]

Just to clarify: you don't stop it the same way you start it. You need a reference to your coroutine instance to stop it.

[orchid bane]

You helped me to remember, yeah

So if I stop my coroutine, at what point will it stop? At random point in the coroutine or at the yield?

[cosmic rain]

At the yield. Coroutines run on the main thread, and there's only one line of code executed on the thread at every given moment. Unless you call stop coroutine from within a coroutine.

In the latter case it would still probably get to the yield.

[pale stream]

I have a quick question. When we try to run the game in the unity engine it runs fine, but when we build and run it, the triggers don't work. We have been trying to figure it out for hours now... Any Ideas?

[dusk apex]

Are there any other differences (platform etc)? Also not a code question, try #💻┃unity-talk

[pale stream]

No other differences we could find, and we aren't sure if its unity or if its code :/ i'll ask there tho

[untold stream]

I have text that is supposed to be shown on a screen. the only issue is I was hoping I could apply a fisheye filter to the test to simulate the rounded screen. how could I do this??

[potent sleet]

not a code question #💥┃post-processing

[digital meadow]

I have some annoying stutter on my player when he moves. I think it is caused by my movement script but I cant figure it out could someone have a look? And I know the script is a complete mess.. https://paste.ofcode.org/ZgWYrtq6qXscp2J6WNE4as

[leaden ice]

make sure interpolation is enabled on the Rigidbody2D

[digital meadow]

the settings I use

[leaden ice]

how are you handling camera follow?

[digital meadow]

I currently use my own script but I also tried Cinemachine and had the same Problem

[leaden ice]

Can you show your script?

[digital meadow]

yeah wait

[leaden ice]

(I do recommend Cinemachine 😉 )

[undone plaza]

Hi guys
Wanted to ask
Is it correct to use UnityEvent to handle input?

[orchid bane]

As you wish

[undone plaza]

Thanks mate

[leaden ice]

in what way? What do you mean by "correct"?

[undone plaza]

I mean if I should do it

[cosmic rain]

What kind of input? How exactly is unity event related to it?

[leaden ice]

the question is too vague ¯_(ツ)_/¯

Can UnityEvent somehow be involved in input handling? Sure.

depends on how you're using it

what you're doing

etc

[undone plaza]

Keyboard and mouse (not mouse movement) input

Is it responsive enough?

[leaden ice]

wdym by responsive?

again what are you trying to do - how is UnityEvent involved?

[undone plaza]

If i detect some input I call some action

[leaden ice]

Ok what would be a problem with that?

[undone plaza]

Idk, is there any problem with that?

That's my question

[leaden ice]

Like what?

[elfin vessel]

hey, what does this error mean?

[undone plaza]

Like it don't being as fast as I need

[leaden ice]

wdym by "fast"? It's fine

[undone plaza]

It is a fps test, so it shouldn't feel laggy or something like that

It should feel instantaneous

[leaden ice]

why wouldn't it?

You think invoking one UnityEvent is going to have impact on your framerate??

if you're really concerned, do it and check the profiler

you probably won't even be able to find it

[undone plaza]

Wellp, that's enough for me

[leaden ice]

If invoking a single UnityEvent in a frame was a problem they wouldn't even be in the engine

[undone plaza]

Thank you mate!

And have a good night

hey guys, since TriggerEnter and Exit are more expensive than using raycasts, I changed my code to help with that. But the problem is that the ray doesn't move from place while in play mode, although in debug it moves correctly like I want to (maybe Update updates differently from DrawGizmos?). Can someone help me fix this problem, which I think is due to the parent of the camera - because when I move it the raycast also moves but I don't understand why and how can I fix it. Thanks!

yellow represents the debug.drawray and the green the current state in update

also hierarchy

[leaden ice]

since TriggerEnter and Exit are more expensive than using raycasts
That's usually not the concern when deciding which of those two to use but ok...
Ray ray = new Ray(playerCam.position, playerCam.forward);
Your ray is explicitly being drawn from the camera's position in the direction the camera is facing so of course it depends on the camera position.

[cyan kernel]

I don't understand the second point, it works while debugging why not in play mode?

[leaden ice]

wdym by "while debugging"?

how is that different from play mode

[cyan kernel]

That's why I made this post. As you can see in the code I posted, I created a ray that should update based on the playerCamera. I tried debugging using Debug.DrawRay on the Update function (the green ray on the video) and also in OnDrawGizmos (the yellow ray) and you can see that they display different results although I'm using the same code

[leaden ice]

show the code for OnDrawGizmos

show the whole script

[cyan kernel]

word limit

[leaden ice]

#854851968446365696

use a paste site

[cyan kernel]

it only has this more

    {
        Debug.DrawRay(playerCam.position, playerCam.forward * pickRange, Color.yellow);
    }```

its just this

[leaden ice]

I mean pretty sure those are equivalent but why didn't you just literally write the equivalent code

ALso you don't need to use OnDrawGizmos for Debug.DrawRay - it's only for Gizmos.DrawXXX stuff

[cyan kernel]

I had it the same before changing to what it is now, I tried to do several things

[leaden ice]

it's unclear to me why in your video it doesn't look like the camera is moving around

it looks like a light is moving around

I'm guessing you have just mixed up an object reference somewhere

[cyan kernel]

it's a flashlight, the camera moves on play mode

[leaden ice]

and seeing the rest of the code may help

Also knowing which object in the hierachy is assigned to playerCam

[cyan kernel]

the main camera

That's all the code for that script

I wish I could explain it better to you but I don't know what else to say lol

[leaden ice]

^

Also making sure you've assigned the camera correctly

and knowing for sure there isn't another copy of this script in the scene

etc

[cyan kernel]

What code do you want? Do you want a specific script? The script is all there

[cyan kernel]

I checked everything

[leaden ice]

You missed something, that's why you're here

[cyan kernel]

It's all right

[leaden ice]

Do you want help or not

[cyan kernel]

But it has nothing to do with the hierarchy or not assigning correctly, I'm sure of it

[leaden ice]

People have been sure of things before and been wrong

Do you have any other copies of this script in scene?

How have you confirmed not?

[cyan kernel]

Of course I want help, that's why I came here, I'm not trying to be rude

[leaden ice]

I'm also not trying to be rude, just asking for more information so I can help

[cyan kernel]

Because I checked all the objects and none of them have this script except the player

[leaden ice]

how did you check

just manually?

[cyan kernel]

yeah

[leaden ice]

Have you done a t:MyScript search in the hierarchy?

Have you done this search at runtime?

[cyan kernel]

Yes

no runtime, how do I do it?

okay I checked it, only on the player

[leaden ice]

just do it while the game is running

And you're sure there's only one copy on the player?

[cyan kernel]

I'm pretty sure it has something to do with the parent of the camera

[cyan kernel]

yes

i'm going to send a video and try to explain

[leaden ice]

I mean one possibility is your camera in Update is being reset to the identity rotation and then some other script such as CM points it at the target

any scripts which deal with camera rotation might be helpful to see

[cyan kernel]

Ok, so as you can see when i change the rotation and position of the CamHolder that is the parent of the Main Camera playerCam it also moves the raycast

[leaden ice]

right so... what scripts/components are involved with the camera?

[cyan kernel]

I have a pretty simple MouseLook script that is on the MainCamera:

{
    [SerializeField] private float sensX;
    [SerializeField] private float sensY;

    [SerializeField] private Transform playerDir;

    private float xRotation = 0f;
    private float yRotation = 0f;

    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }

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

        yRotation += mouseX;
        xRotation -= mouseY;

        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.rotation = Quaternion.Euler(xRotation, yRotation, 0f);
        playerDir.rotation = Quaternion.Euler(0f, yRotation, 0f);
    }

}```

[leaden ice]

you shouldn't multiply mouse input by deltaTime btw

[cyan kernel]

The CamHolder that is the parent

[leaden ice]

it's going to make things stuttery

[cyan kernel]

thanks, going to change it now

[leaden ice]

what is playerDir

[leaden ice]

you'll need to reduce the sensitivity variable to compensate, but it will become smoother overall

[cyan kernel]

It's a invisible game object that points in the direction of the player

it's a child of the player

[leaden ice]

Orientation?

[cyan kernel]

yeah

[leaden ice]

CamHolder has no components on it (other than Transform)?

[cyan kernel]

that's what i was going to say now lol

it has a move camera script that makes the camera follow around the player, it basically just changes the position of the camholder to be the same as the camposition (child of player)

    
    void Update()
    {
        transform.position = cameraPosition.position;
    }```

I did this so the Player and Camera stayed separated

[leaden ice]

There's a component called PositionConstraint that will do this btw

[cyan kernel]

Really? didn't know about it

I place it in the camholder or the camposition?

[leaden ice]

it replaces your small script here

[cyan kernel]

how does it work

what do i change?

[leaden ice]

you give it a target

and it will follow that target

[cyan kernel]

and put the weight to right

[leaden ice]

it also handles offsets, weighted following of multiple targets etc...

anyway...

as for your actually original question, I'm still not sure 🤣

you're sure that green gizmo isn't drawn by a different script?

[swift falcon]

how to stop texture bleeding from an atlas in a minecraft game?

[cyan kernel]

yeah im absolutely sure, it's my only debug.drawray that im using

[west sparrow]

Make sure mipmaps are disabled on the texture and point as a filter mode. If the bleed still happens, look at adding padding to the atlas

[swift falcon]

mipmaps on and off do nothing. turning it off seems to do the trick in the scene view

[cinder kindle]

        if (Input.GetMouseButtonDown(0))
        {
            while (Input.GetMouseButtonDown(0))
            {
            GunInfo gunInfo = new GunInfo();
            float fireRate = gunInfo.fireRate;

            StartCoroutine(waiter(fireRate));
            items[itemIndex].Use();
            }
        }

Does anyone know how I can get the info of the current gun?

[leaden ice]

Certainly not like this. This is an infinite loop

[clever spade]

also creating new GunInfo every single time

[leaden ice]

Wdym by "info"

[cinder kindle]

ik

[clever spade]

if you want information from something then it needs to be referenced

[cinder kindle]

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

[CreateAssetMenu(menuName = "FPS/New Gun")]
public class GunInfo : ItemInfo
{
    public float damage;

    public float fireRate;
}

[leaden ice]

Ok but.mm Are you storing these in a collection somehow?

How are you associating these with different guns

And why are you writing a while loop

And why are you creating a new one

[cinder kindle]

thats place holder

https://pastebin.com/cxDJ3SJX

[cinder kindle]

thats the whole script of this

[leaden ice]

I would expect a collection of GunInfo somewhere

Or at the very least a single reference to the current gun

[cinder kindle]

wait

I can move it out of the player controller

into another script

that has the reference

the main script

that fires the gun

    void Shoot()
    {
        Ray ray = cam.ViewportPointToRay(new Vector3(0.5f, 0.5f));
        ray.origin = cam.transform.position;
        if(Physics.Raycast(ray, out RaycastHit hit))
        {
            hit.collider.gameObject.GetComponent<IDamagable>()?.TakeDamage(((GunInfo)itemInfo).damage);
            PV.RPC("RPC_Shoot", RpcTarget.All, hit.point, hit.normal);
        }
    }

Would this work?

If I put it somewhere in there *

I am having trouble figuring out how to implement the network variable so that it is applied to all clients and the host. I want my 2D character to flip horizontally on all clients, as well as on the host. Currently, the host can move and the clients can see the host move, and the host can see the clients move. However, I am experiencing difficulty syncing the flipX for the sprite renderer across all clients and the host.

I'm pretty sure I have to do something in OnValueChanged but damn I can't find out...

If someone can help me, full code is here: https://forum.unity.com/threads/i-am-having-difficulty-understanding-networkvariable.1386966/

[trim spoke]

Hi guys , please help. have a raycast performance issue. but i dont even use it. how can you find the source object the uses it? profiler doesnt mention any script/object

[west lotus]

Enable deep profiling

[trim spoke]

enabled , one sec sending shot

[west lotus]

Thats the ui raycaster...interesting why its taking 3 ms

It would seem that the raycaster is being called for every object in the canvas when you move the mouse for example. So I guess you have 179 ui objects. My solution. Split your ui into multiple canvases each with its own graphics raycaster and remove the one from the root canvas

That way it wont iterate over disabled objects

[mossy snow]

how many GraphicRaycasters are in your scene?

[trim spoke]

Problem found. I had many text prefabs instantiate with raycast component attached to them

[scarlet bane]

Im making a game, and the main damage is throwing explosive projectiles at enemies

But as the game progresses, as i shoot multiple projectiles and hit multiple enemies

It get laggy

[woeful leaf]

Do the projectiles despawn?

[scarlet bane]

What in my code / project should i look at to reduce lag?

[scarlet bane]

Yeah

[woeful leaf]

In what way

[scarlet bane]

Destroy

[woeful leaf]

Hm

[scarlet bane]

I have reference images

ive given to them

[woeful leaf]

Maybe consider implementing pooling

[scarlet bane]

should i remove those

What that revolve around?

[woeful leaf]

I don't know the context of that reference

[woeful leaf]

What?

[scarlet bane]

What would that involve*?

[thin aurora]

Try adding pooling https://docs.unity3d.com/ScriptReference/Pool.ObjectPool_1.html

[main shuttle]

Profile the problem first. Currently your just guessing what the problem is.

[woeful leaf]

Making it so that you don't Destroy objects, but set them inactive to reuse them first

[scarlet bane]

My enemies are 2d animation based, but i use an image to check sizing

[woeful leaf]

That's what I said but thanks for providing the docs

[thin aurora]

This is most likely not too related to pooling but it's a good idea to start with this

[woeful leaf]

Yup

[thin aurora]

Oh right, didn't see lol

[woeful leaf]

It could maybe be this but we'd require more context

If you could share code that'd help

[scarlet bane]

Yeah im ok to share code

Its just that idk where to start

I could break down how i go about things

[woeful leaf]

I don't know how large it is, but I'd just share the relevant code

Probably in paste sites by the sound of it

#854851968446365696 for that

[scarlet bane]

Yeah ill do it after but ill tell u the gist of it first

[woeful leaf]

Sure

[scarlet bane]

So first I suck up a bunch of enemies, they are stored into a list.

I intend this to be a wave ebased game

Then shoot them out

But as a seperate projectile object

[hexed pecan]

Are you using some physics query like Physics.OverlapSphere?

[scarlet bane]

E.g. i suck up 6 enemies (set them inactive) then instantiate 6 projectile gameobjects

After the projectile game objects collide, they destroy itself, then instantiate the sucked enemy

[woeful leaf]

Why are you pink now reee

[scarlet bane]

Then instantiate an a explosion for each projectile collision that does damaage to each enemy hit

[woeful leaf]

Roughly, how many objects are you creating at once?

[scarlet bane]

So e.g. the 6 projectiles collide with a wall then 6 enemies are spawned in the collision place and then 6 explosions are

instantiated then destory + damage calculation

[main shuttle]

It's purple though

[woeful leaf]

So 18 objects

[scarlet bane]

yuh

but the thing i think lags it

[woeful leaf]

But it doesn’t lag at the start?

[scarlet bane]

is that each explosion can hit each of the one enemy

so there will be 36 collisions

with explosion and enemies

[hexed pecan]

Start with sharing the code?

[scarlet bane]

Sure

Uh is there a format i have to share it in

Im new to this

[main shuttle]

#854851968446365696 at the bottom

[woeful leaf]

^

[woeful leaf]

^

[scarlet bane]

Alright one moment

https://paste.ofcode.org/6MLuJzq8bK3rZA7WBZNNuY

[main shuttle]

Still, if you would profile it, you would know if the instantiation is the problem, the explosions effects, or the physics checks are the problem. Maybe a combination.

[scarlet bane]

Im not quite sure

I think its the fact that this collision i sent

can happen alot of times

[hexed pecan]

name.Contains doesnt look very good

[scarlet bane]

Yuh, its my first time using unity lmao

[hexed pecan]

(Regardless of any of this speculation, profile it)

[scarlet bane]

I know my design and style is bad

Not sure what that even means 😭

I should be in beginner chat

[thin aurora]

Code for damagePopup?

[lyric moon]

if i reference something in a scene (in a script that is not in that scene) and then unload and reload that scene, will that reference still work?

[thin aurora]

Pretty sure the reference will turn "missing"

[scarlet bane]

https://paste.ofcode.org/yMGHm7PYmGgB4M5ug8yirh

I already know there will be alot of problems

[thin aurora]

Hmm, maybe just use the profiler

[hexed pecan]

Would add an Enemy tag to the enemies and then use .CompareTag("Enemy") instead of the whole name contains check

[thin aurora]

Nothing weird in these scripts

Pooling will definitely help if you have this instantiate often

[scarlet bane]

Do u think it would lag

[thin aurora]

But it should not lag

[scarlet bane]

if that code that to run in one instant like 40 ish times?

[main shuttle]

Also, instantiating world UI objects without a pool seems inefficient to me, afaik they are quite expensive.

[scarlet bane]

So maybe pooling?

[woeful leaf]

100% pooling

Like the best it can do is improve your performance

The worst it can do is still just have a better system kek

[scarlet bane]

Yeah fair

[woeful leaf]

So it’s a win win

[scarlet bane]

How taxing is having to instantiate an extra image

[woeful leaf]

You’d have to profile that

Just go apply pooling and see what that does

[scarlet bane]

Alright, i should do some more testing to delve into what lags

ill try taking out the damage canvas

also

and the hp canvas

to see if that changes anything

[woeful leaf]

Profiler

[scarlet bane]

O

Sorry I thought u guys were talking about note taking or something

Didnt profile was for checking performance

Apologies

[woeful leaf]

Also do the compare thing Osmal said

[main shuttle]

Ah, that explains it 😅

Was wondering why you just wouldn't open the profiler

[scarlet bane]

Also i was making a mobile app

And the thing is about the lag, is that u dont usually lag until late into the game

And u cant get late into the game without playing on the mobile

LOL

I havent been doing much testing till recently

So i should just make some testing scripts

[woeful leaf]

You should look into how you use the profiler

[scarlet bane]

Yeah definitely

[woeful leaf]

Maybe something is somehow hogging a bunch of memory

Since it is something long-term

[scarlet bane]

I have one more main problem

So i had my designer design a start menu screen

And i was gonna add buttons overtop the menu screen he drew

[woeful leaf]

Is it a coding problem

[scarlet bane]

Yeah

[woeful leaf]

Okay, fair, continue

[cosmic rain]

Mobile are susceptible to overheating. When they do, they throttle down performance.

[scarlet bane]

But Im not sure

[cosmic rain]

High and often resources usage can make mobile devices heat up faster.

[scarlet bane]

How to make the buttons stay consistent with the location of the menu screen background

Instead of relative to resolution

of the mobile screen

Im not sure if u guys get what i mean

[scarlet bane]

Yeah, i think ive lagged testing on Unity before lao

[cosmic rain]

Use anchors.

[scarlet bane]

Yeah so i tried using anchors

[woeful leaf]

Try harder lol

[real anvil]

Does Unity have a way to calculate GPU VRAM usage at runtime?

Im running out of VRAM and need to cap it before the app just kills itself

[woeful leaf]

Profiler?

[scarlet bane]

But i doesnt make the button stay same position relative to the background image

[real anvil]

It's all done at runtime

Can't profile it

[woeful leaf]

What

[real anvil]

Runtime on iOS I should say sorry

And it's user generated

So I can't predict how much will be used

[scarlet bane]

NVM I see gotta anchor to the image

[woeful leaf]

I told you

[slender nacelle]

hi guys, im trying to user the profiler to identify an issue in my code, but im not sure how to use it to drill further down into the issue, atm it just says this one script is consuming all the resources, but the update functional does a few things, is it possible for this profiler tool in unity to help me narrow it down further?

[cosmic rain]

You can place profiler markers to profile specific piece of code. Check the Profiler page in the API docs.

But from the look of it, the issue seems to be with memory allocations, so it shouldn't be hard to identify the culprit.🤔

[slender nacelle]

yeah like creating something over and over again, i reckon.. but i dont think i am..

[outer radish]

Hello, i am trying to get the height and width of a texture2D but unity always limits the texture to 2048x1024 although I changed the MaxSize in the settings of the Texture to 4096. Does anyone know why?

[outer radish]

I wanna get the real resolution of the Texture

[woeful leaf]

I don't think this is code releated

I've got a question about inheritence, I don't quite understand how to work with constructors in combination with inheritence. I'm trying to run the inherited constructor, if even properly possible
This is currently my code

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Events;

public class MainMenuButton : MonoBehaviour
{
    public Button button;
    public UnityAction onClick;

    public MainMenuButton(UnityAction onClick) 
    {
        button = GetComponent<Button>();
        this.onClick = onClick;
        button.onClick.AddListener(onClick);
    }

    private void OnDisable()
    {
        button.onClick.RemoveListener(onClick);
    }
}

using UnityEngine;
using UnityEngine.Events;

public class Quit : MainMenuButton
{
    public Quit(UnityAction onClick) : base(onClick)
    {
        onClick = Die;
    }

    private void Die() 
    {
#if UNITY_EDITOR
        UnityEditor.EditorApplication.isPlaying = false;
        print("I quite the damn game");
#else
    Application.Quit();
#endif
    }
}

I'm trying to run the base in in the latter

But not sure how to

[slender nacelle]

you cant use a constructor with monobehaviours its done automatically by unity im pretty sure

you can only instantiate a monobehaviour

[woeful leaf]

So what I'm trying to do isn't possible?

[slender nacelle]

i dunno what youre trying to do sorry

[late lion]

But if this wasn't a MonoBehaviour, it still probably wouldn't work because it looks like you're trying to set onClick = Die before the base constructor is called. : base(args) will run the base constructor first. There's no way to run the base constructor after the derived one.

[woeful leaf]

Ah so it's an order of execution issue

That is unsolvable

[late lion]

But Sirix's point also stands. You cannot use constructors with MonoBehaviours.

[woeful leaf]

Righty, thanks for the info

I suppose it's time for me to figure out a different approach then heh

[late lion]

If you instead have an Initialization method, then you can more finely control the order of things

Make it virtual in the base class and override it in the derived class. Then you can choose when to call base.Initialize(args) in the derived override

[woeful leaf]

Yeah I suppose I could replace the constructor with a method like that

[woeful leaf]

Yeah that was what I was thinking, thanks

[slender nacelle]

    private void Update()
    {
        Profiler.BeginSample("Unit Update");
        GridPosition newGridPosition = LevelGrid.Instance.GetGridPosition(transform.position);
        if ( newGridPosition != _gridPosition )
        {
            GridPosition oldGridPosition = _gridPosition;
            _gridPosition = newGridPosition;
            
            LevelGrid.Instance.UnitMovedGridPosition(this, oldGridPosition, newGridPosition);
        }
        Profiler.EndSample();
    }

this code was fine previously and i dont think anythings changed but this is like 99.5% of the GC calls

    public GridPosition GetGridPosition(Vector3 worldPosition)
    {
        return new GridPosition(
                Mathf.RoundToInt(worldPosition.x / CELL_SIZE),
                Mathf.RoundToInt(worldPosition.z / CELL_SIZE),
                Mathf.RoundToInt(worldPosition.y / CELL_SIZE)
            );
    }

dunno how else to do this but i dont think this should be that bad?

[late lion]

Is GridPosition a class?

[slender nacelle]

yes

am i reading this right?

[late lion]

If you change it to a struct, like Vector3, then there will be no GC.Alloc from creating thhem.

[slender nacelle]

like no jk though, a week ago these calls had no issue, what the heck did i change

its all the same

i switched from an array to a list... but... this code doesn't interact with that

[late lion]

Are there more of them?

[slender nacelle]

yeah, im aware of structs etc , didnt think i needed to use them for this

more what sorry

[late lion]

More units

[slender nacelle]

just 1 unit in the game with this test

[clever spade]

@woeful leaf just skimmin a bit through here but Start was ment to be used in place of constructors. You can override the start method

[late lion]

Then there must be an error because it looks like you're creating 29000 objects.

[slender nacelle]

yeah!! thats what i thought haha

the heck

[woeful leaf]

Oh yeah I should probably just use the Start or OnEnable

[slender nacelle]

would they show up in the scene hierachy **

[late lion]

These are just C# objects, so no

[slender nacelle]

ah makes sense, what on earth have i done...

so somewhere im saying 'new' in updates or something?

[late lion]

What does LevelGrid.Instance.UnitMovedGridPosition do, since that's also within the profiler sample?

[slender nacelle]

    {
        RemoveUnitAtGridPosition(fromGridPosition, unit);
        
        AddUnitAtGridPosition(toGridPosition, unit);
        
        OnAnyUnitMoveGridPosition?.Invoke(this,EventArgs.Empty);
    }```

hmmm

[crimson crow]

GridPosition newGridPosition = LevelGrid.Instance.GetGridPosition(transform.position) this will make a new GridPosition every frame

[cosmic rain]

What do these remove and add methods do?

Also, what's subscribed to the event?

[slender nacelle]

    public void AddUnitAtGridPosition(GridPosition gridPosition, Unit unit)
    {
        GridObject gridObject = gridObjects.FirstOrDefault(g => g.gridPosition == gridPosition);
        if (gridObject != null) 
        {
            gridObject.AddUnit(unit);
        } 
        else
        {
            //throw excpetion? 
            Debug.LogError($"No GridObject at position {gridPosition}");
        }
    }

i think this is it... right

[cosmic rain]

And remove?

[slender nacelle]

    public void RemoveUnitAtGridPosition(GridPosition gridPosition, Unit unit)
    {
        GridObject gridObject = gridObjects.FirstOrDefault(g => g.gridPosition == gridPosition);
        if (gridObject != null)
        {
            gridObject.RemoveUnit(unit);
        }
        else
        {
            //throw excpetion? 
            Debug.LogError($"No GridObject at position {gridPosition}");
        }
    }

same thing basically

nah that can't be it these aren't called often

[cosmic rain]

What are grid objects? Where do you populate the collection?

Or, I guess it's not.

[late lion]

With this many allocations with only 1 unit, there must a loop somewhere. Does gridObjects only contain one object?

[slender nacelle]

gridobject has a list of units

    public GridObject(GridPosition gridPosition)
    {
        this.gridPosition = gridPosition;
        _unitList = new List<Unit>();
    }

[cosmic rain]

Where do you construct it?

[slender nacelle]

        foreach (Cell cell in world.Cells)
        {
            GridPosition gridPositionOfCell = new GridPosition(cell.X, cell.Y, cell.Size.Z);
            GridObject gridObject = new GridObject(gridPositionOfCell);
            gridObjects.Add(gridObject);
        }

in awake of levelgrid

[mental rover]

why include Profiler.BeginSample here? Unity will sample Update on MonoBehaviours for you

[slender nacelle]

i dunno, was trying to figure it out, havent used the profiler before haha

[cosmic rain]

And how many cells are there?

[slender nacelle]

checkin

[cosmic rain]

Actually nvm. That doesn't matter much.

[slender nacelle]

400.. not that many i think?

which is right for my map anyway

[cosmic rain]

I'd use the memory profiler to see what takes the memory.

[slender nacelle]

whats the memory profiler called?

dw ill google it, thanks for the help

[cosmic rain]

Can you share the whole code of GridPosition

[slender nacelle]

using System;
using UnityEngine;

public struct GridPosition : IEquatable<GridPosition>
{
    public bool Equals(GridPosition other)
    {
        return this == other;
    }

    public override bool Equals(object obj)
    {
        return obj is GridPosition other && Equals(other);
    }

    public override int GetHashCode()
    {
        return HashCode.Combine(x, z);
    }

    public int x;
    public int z;
    public int yLevel;

    public GridPosition(int x, int z, int yLevel)
    {
        this.x = x;
        this.z = z;
        this.yLevel = yLevel;
    }

    public override string ToString()
    {
        return $"x: {x}; z: {z} lv: {yLevel}";
    }

    //BUG: this isn't checking yLevel
    public static bool operator ==(GridPosition a, GridPosition b)
    {
        return a.x == b.x && a.z == b.z;
    }
    
    public static bool operator !=(GridPosition a, GridPosition b)
    {
        return !(a==b);
    }
    
    public static GridPosition operator +(GridPosition a, GridPosition b)
    {
        return new GridPosition(a.x + b.x, a.z + b.z, a.yLevel + b.yLevel);
    }
    
    public static GridPosition operator -(GridPosition a, GridPosition b)
    {
        return new GridPosition(a.x - b.x, a.z - b.z, a.yLevel - b.yLevel);
    }
}

[cosmic rain]

Oh, so you changed it to struct?

[slender nacelle]

oh.. lol i must have...

sorry i forgot

ages ago

[cosmic rain]

So is it any different now? The profiler data.

[slender nacelle]

no sorry, i did this change months ago when it was working fine

trying to figure out how to install this memory analysis - got it

[cosmic rain]

Well, since it's not GridPosition, it must be one of the methods here or the event(something subscribed to it to be precise).

[slender nacelle]

is it possible the event is sub'd to something that doesn't show in the code?> i think ive had something like that before

[cosmic rain]

Although... It's weird that the profiler is not being precise about it.

[slender nacelle]

like its an old thing

[cosmic rain]

No.

You can find all references in the ide.

[mental rover]

you can use the profiling markers around specific blocks to narrow it down further

can you also remove the Profiling.BeginSample lines and check again (it's likely irrelevant, but you're actually profiling the profiling at the moment as well)

[slender nacelle]

it says this block is also really bad but like...

    private void HandleSelectedAction()
    {
        Profiler.BeginSample("HandleSelectedAction Update");
        if (Input.GetMouseButton(0))
        {
            GridPosition mouseGridPosition = LevelGrid.Instance.GetGridPosition(MouseWorld.GetPosition());

            if (selectedAction == null)
            {
                return;
            }

            if (!selectedAction.IsValidActionGridPosition(mouseGridPosition))
            {
                return;
            }
            
            if (!selectedUnit.TrySpendActionPointsToTakeAction(selectedAction))
            {
                return;
            }
            
            SetBusy();
            selectedAction.TakeAction(mouseGridPosition,ClearBusy);
            OnActionStarted?.Invoke(this, EventArgs.Empty);
        }
        Profiler.EndSample();
    }

its only running when the mouse is down

the heck

invoking some event on update? i must be

[mental rover]

BehaviourUpdate captures all classes that are using Update()

[slender nacelle]

or is that when i press mouse down? and it runs that event

[mental rover]

you've linked 3 images with different classes using Update

[slender nacelle]

sorry 😦

[mental rover]

just trying to help you identify the issue - your first post was in the update call of UnitActionSystem, but then you linked another in Unit, and this one is in EventSystem

I'm not sure if you're shifting code around/renaming it

[slender nacelle]

yeah there is a few going on 😅

im not there are just a few GC allocs in a few functions

[cosmic rain]

This is not Update though

[slender nacelle]

    private void Update()
    {
        if (isBusy)
        {
            return;
        }

        if (!GameManager.Instance.HasBattleStarted())
        {
            return;
        }

        if (TurnSystem.Instance.IsEnemiesTurn())
        {
            return;
        }

        if (EventSystem.current.IsPointerOverGameObject())
        {
            return;
        }

        if (TryHandleUnitSelection())
        {
            return;
        }

        HandleSelectedAction();
    }

[cosmic rain]

Can you remove the useless profiler samplers and enable deep profiling?

[mental rover]

in the profiler Update() calls will show under BehaviourUpdate as {ClassName}.Update() [Invoke]

[slender nacelle]

yep will do now

omg deep is working wonders

ok i know where to start looking

    private PathNode GetNode(int x, int z, int yLevel)
    {
        GridPosition gridPosition = new GridPosition(x, z, yLevel);
        return _pathNodes.FirstOrDefault(pn => pn.GetGridPosition().x == gridPosition.x &&
            pn.GetGridPosition().yLevel == gridPosition.yLevel &&
            pn.GetGridPosition().z == gridPosition.z);
    }

[clever spade]

That's being called every update?

[slender nacelle]

no

wait what

it should run this once when i move then thats it

not continously

[clever spade]

how many tiles do you have exactly?

[slender nacelle]

~400

turn based game though

[clever spade]

im going to assume the best and say that is 20x20

[slender nacelle]

yep

[cobalt wraith]

HEya!
What would be a good way to approach IK for legs?
My goal is to let the feet/legs/knees bend naturally, depending where the character stands.

I currently have a ray shooting down from the characters feet, and changing the collider accordingly so the feet match

If that made any sense x)

[slender nacelle]

yep ive fucking found it..

[cosmic rain]

Seems like it's your pathfinding system.
The allocation is probably from Linq.

[slender nacelle]

im pretty sure

yeah

while the unit is moving around im constantly checking for a path

[clever spade]

that and you should cache "GridPosition(x, z, yLevel);"

[slender nacelle]

it should just it once

yeah 100% ive recently refactored a bunch and havent finished it cause i ran into this issue

           var pathFound = Pathfinding.Instance.FindPath(unitGridPosition, gridObject.gridPosition, out int pathLength);
            if (pathFound == null)
            {
                continue;
            }

its this code im certain

[mental rover]

you just linked the call stack here

[woeful leaf]

https://paste.myst.rs/9lx69tzp
I ended up with this a solution by the way, I think it's decent

[thin aurora]

I did not read anything about this but if you want to create a proper system for this, you might want to create a general "initialization" method that is virtual. You can then call this method and override if needed. You can also go one step further and create your own Instantiate method that will invoke this method using reflection, but this will have a hit on performance. You can look into adding source generation for this if you know how to do it.

[thin aurora]

Works too. Basically what I said, but with a method and abstract

[late lion]

Looks like a more complicated version of:

public abstract class MainMenuButton : MonoBehaviour
{
    private Button button;

    private void OnEnable()
    {
        button = GetComponent<Button>();
        button.onClick.AddListener(OnClick);
    }

    private void OnDisable()
    {
        button.onClick.RemoveListener(OnClick);
    }

    protected abstract void OnClick();
}

And then the derived class just overrides OnClick

public class Quit : MainMenuButton
{
    protected override void OnClick()
    {
        #if UNITY_EDITOR
        UnityEditor.EditorApplication.isPlaying = false;
        #else
        Application.Quit();
        #endif
    }
}

[woeful leaf]

Oh yeah you're totally right, I needlessly over-complicated it 😅
Thanks for the tip!

[slow crag]

What is the best way to get correct world-space coordinates regardless of my camera angle? In this video, you can see that when the camera is top-down, it correctly displays coordinates of tiles in the tilemap. However, when I change perspective, it gets screwed up.

[mossy snow]

project ray onto plane of tilemap, use GridLayout's WorldToCell to get tile coordinates. Hard to provide any other information when you don't say how you're doing it now

[lament bear]

Hello,
I have a 2D grid-based game with some randomly generated levels. I can spawn objects on the grid, but I want to randomly instantiate several 2x2 (grid cell) prefab objects as well, which should fit into valid patches of the cell grid (i.e. playable space, and not cut into walls).

Is there a best practice for evaluating available spaces that the object can go? I can think of many approaches to this, but my ideas all have either flaws or generate more overhead than I'd like.

For example, if I loop through the available cells, I can easily check if there's space, but then I am severely weighting the chance of instantiation towards the earlier coordinates. I want a roughly equal chance to appear at all possible positions. I could loop through and log all possible positions into a list, but that seems extremely cumbersome. I feel like there's a method I'm overlooking.

[slow crag]

Thanks EvilReeper, that worked.

[autumn cipher]

how do you find the point of where the raycastall gets out of the collider?

when you shoot a ray through a box, I'm trying to find the end point of the raycast

[autumn cipher]

I guess I can't find it since ray getting out of the collider not considered a collision?

[past pier]

Brain twister: how the hell does this method allocate?
private static List<Box> FindBox(Piece piece) => FindSidesOfBoxOrCube(piece, FormValidTwoDimensionalBoxSide, OneSideAllowed);
Not the method it calls. THIS method.

However just in case, for completeness sake:

        private static List<Box> FindSidesOfBoxOrCube(Piece piece, Func<Vector3, Vector3, Vector3, Vector3, bool> isValidSide, int numberOfSides)
        {
            boxes.Clear();
            var boxName = 'A';
            var snapNodes = piece.PrimarySnapNodes();
            for (var i = 0; i < snapNodes.Count; i++)
            {
                for (var j = i + 1; j < snapNodes.Count; j++)
                {
                    for (var k = j + 1; k < snapNodes.Count; k++)
                    {
                        for (var l = k + 1; l < snapNodes.Count; l++)
                        {
                            if (isValidSide.Invoke(snapNodes[i], snapNodes[j], snapNodes[k], snapNodes[l]))
                            {
                                boxes.Add(new Box(boxName++, snapNodes[i], snapNodes[j], snapNodes[k], snapNodes[l]));
                            }
                        }
                    }
                }
            }

            return boxes;
        }

(the boxes list as you see is not initialized but reused from the static context of the struct)

And:
private static bool FormValidTwoDimensionalBoxSide(Vector3 snapNodeA, Vector3 snapNodeB, Vector3 snapNodeC, Vector3 snapNodeD) => snapNodeA != snapNodeB && snapNodeA != snapNodeC && snapNodeB + snapNodeC - snapNodeA == snapNodeD;

[woeful leaf]

That's not normal

[scarlet bane]

Im also getting random spikes in physics

[woeful leaf]

Animation is actually a huge part of it, what are you doing with that?

[woeful leaf]

So your game basically just implodes after a while

Curious

[scarlet bane]

Yeah

LOL

I have a frenzy spawn mode

where an enemy spawns every 0.5 seconds

and the game just dies

that big chunk was from the explosion i told ytou about

I have like simple

few frame animations

for the enemies, explosions

[vagrant blade]

Having that many physics objects is going to kill your performance pretty fast.

[scarlet bane]

What does it mean by physics objects

[vagrant blade]

Objects with rigidbodies

[scarlet bane]

o

Just my player and enemies

How do games manage large waves of enemies usually then?

[frigid anvil]

Most of them aren't physics objects; they have simplified physics, if any... At least for large swarm games.

[cosmic rain]

👆 That or they have special architecture, like ECS

Sometimes both

[woeful leaf]

What does ECS stand for again?

[cosmic rain]

Entity Component System

[scarlet bane]

For example survivor.io

[woeful leaf]

Ah righty

[scarlet bane]

they have a bunch of abilities

and huge waves of enemies

are spawned

[cosmic rain]

Doesn't seem too much from the gameplay videos I found online.

Should be possible with the regular workflow.

[trim rivet]

I am trying to change my post process volume values via c#, but they bounce back to the preset values...
Anyone know what I might be missing?

[scarlet bane]

Yuh i think the main problem, is my explosions

[cosmic rain]

If you look closely, you'll see that "other" is taking most of the time. It's probably the editor loop. Try profiling a build.

[scarlet bane]

Sorry, to sound clueless

But how would i go about doing that

[frigid anvil]

So I've never heard of that game, and they don't have their own domain which is...weird, but looking at a quick gameplay video, I'm quite confident those aren't physics objects. Imagine Robotron 2084, which ran on hardware several exponentiations worse than the dumbest smartphone, and it handled that many onscreen easily. You just simplify the AI significantly.

[scarlet bane]

I know how to make an apk

[cosmic rain]

Google that. It's very simple: "unity profile android build"

[woeful leaf]

I'm confused as to why it doesn't exist

[scarlet bane]

Its too confusing

So many steps

[quaint rock]

gamedev has many many steps

once you follow through and profile something a few times the workflow will seem easy for it

[scarlet bane]

NVM

figured it out

[scarlet bane]

This is is what it looks like normally

[knotty sun]

because you have defined UIElement as a varaible so it stops being a type in that script

[woeful leaf]

Oh wait I'm stupid it just has to be of type GameObject ofc, my bad

Yeah no it makes sense now, my bad

[scarlet bane]

This is what i looks like when i do the large explosion

It alot of script lag

[cosmic rain]

Okay, well, select a frame and look at the profiler hierarchy view for what's causing it.

[cosmic rain]

How did it go back to profiling the editor..?😞

But either way, seems like it's something with physics.

What exactly is happening during your "explosion"?

[scarlet bane]

ya u told me afte rso i unplugged me phone sry

I was moving it around

and i found this

So it might be the damage canvas

[cosmic rain]

460 calls to DamagePopup.Update.

Are you sure you need 460 popups?

[scarlet bane]

Yeah thats what i was talking about before

Say i have 20 enemies

each enemy generates a explosion

[woeful leaf]

What kind of exponential function are you using?

[scarlet bane]

which will hit each other enemy

so there are like 400 collision 🤣

[cosmic rain]

What do they have to do with popups though?

[scarlet bane]

Each collision

causes damage

which creates a damage popup

[cosmic rain]

Then how about pooling them??

[scarlet bane]

Maybe i need to fix my game logic

[cosmic rain]

It seems like Destruction of objects is the main issue

[scarlet bane]

Ill try taking out

[violet wing]

Does anyone who knows about Growtopia know how their world saving system works and how hard it would be to make something like that?

[scarlet bane]

the damage canvas and see if it still lags

then if it still does

ill check out poolijng

[scarlet bane]

So i took out the damage canvas

ANd now its just purely the physics thing

[cosmic rain]

Well, why not expand it..?

[scarlet bane]

Sorry im not the brightest

Ok I get it now

I need to use pooling 😹

[woeful leaf]

You're only now going to implement that?

[scarlet bane]

I was at soccer until i started debugging like 30 minutes ago

[woeful leaf]

Oh okay, I was about to say that I suggested it <t:1673857620:R>

[scarlet bane]

Ya, i got home started investigating this mysterious profiler relic u told me about

[woeful leaf]

Yeah that's fair

[scarlet bane]

Then used it find out the optimal solution to my conundrum

[dapper schooner]

Is it possible to read the contents of a prefab? Like check how many buttons are contained inside a prefab?

[leaden ice]

prefabs are GameObjects like any other

they're just not active and in the scene

You can freely use the whole of the API with them

[silk horizon]

Anyone else have the same mistake

[dapper schooner]

Good to know. Im making an editor script and wanted to populate a list with just the buttons of the selected prefab

Thx

Hello, im having a strange issue where if i am rotating an object and using transform.Translate() in the same frame the object starts to fly in circles sometimes.

public void Move()
{
  Vector3 lookPos = anotherPos - transform.position;       
  Quaternion rotation = Quaternion.LookRotation(lookPos);
  transform.rotation = rotation;

  transform.Translate(Vector3.forward * Time.deltaTime);
}

I dont understand whats going wrong here.

[leaden ice]

Translate is relative to the object's local space, so rotating it changes the direction you translate

if you want to Translate in world space do transform.Translate(Vector3.forward * Time.deltaTime, Space.World);

[candid trench]

well, yea, i wanna translate it forward in whatever direction i have rotated it to tho

so should i not translate in localspace?

[leaden ice]

then that's exactly what's happening

you are rotating it in a circle

so it's moving in a circle

Also lookPos is a confusingly named variable. It's not a position vector, it's a direction. Would be more clear as lookDir for example

[candid trench]

fair enough.

But i still dont understand whats going wrong

Like, i feel like im rotating the object, thereby moving its forward vector. So then when i want to move it i should move it just forward in local space using the forward vector.

What im expecting then is for the object to just rotate towards whatever point i chose and then have it move towards that point.
No moving in circles or whatever.

[leaden ice]

Is the point you're moving towards itself moving??

[candid trench]

no, thats a static point

[leaden ice]

Is the object you're moving towards, for example, a child of the object that this script is on?

can you show how you have set things up

[candid trench]

i can try record a small demo, hang on

[leaden ice]

basically you have one of a couple issues most likely:

• the point you're moving towards is itself moving, resulting in constantly changing directions (e.g. if the target is a child of this object)
• You're overshooting the point and your object is then having to turn around and double back, ad nausuem

[candid trench]

- You're overshooting the point and your object is then having to turn around and double back, ad nausuem
This could actually be it, currently my margins are 0.1f but im normalizing a vector so i should maybe simply just use 1 insted

or i mean, i was using a normalized vector, before i changed to vector3.forward but seeing as both should have a magnitude of 1 maybe my implemented guard clause to see how far i have left to the target should also have < 1 rather than < 0.1f

[leaden ice]

You could simplify this whole thing by just using MoveTowards and LookAt

[devout silo]

I have a script for swimming, and there is a variable that changes between swimming mode and normal mode. Now, I have a if statement that says if the variable is on swim mode, the walk code is disabled.
Until now it was working fine, but suddenly it doesn't listen to the statement and swimming mode runs concurrently with normal mode. I do not know what to do. help?

[candid trench]

ill take a look at using those insted

[leaden ice]

public void Move()
{
  transform.LookAt(anotherPos);
  transform.position = Vector3.MoveTowards(transform.position, anotherPos, Time.deltaTime);
}``` @candid trench

[woeful leaf]

Is it possible make custom error mesages have bold text?

Or something that gives it more of an emphasis

[scarlet bane]

I just realised

Using a pool would be very difficult

because i would need to pool like 500 objects...

Would it be ok to have an object pool of like 1k?

[candid trench]

hang on, why am i not allowed to declare 2 variables with the same name here??

    public void Move()
    {
        if (tilePath.Count() > 0)
        {
            transform.LookAt(tilePath[tilePath.Count() - 1].position);

            if (tilePath[tilePath.Count() - 1].isOccupiedBy == null)
            {
                transform.position = Vector3.MoveTowards(transform.position, tilePath[tilePath.Count() - 1].position, Time.deltaTime * moveSpeed);

                float distanceToNextTile = (tilePath[tilePath.Count() - 1].position - transform.position).magnitude;
                float distanceToCurrentTile = (currentTile.position - transform.position).magnitude; 
                // Why am i not allowed to declare this twice?
                // shouldnt this be going out of scope before i try to declare it again?

                if (distanceToNextTile < distanceToCurrentTile)
                {
                    currentTile.isObsticle = false;
                    currentTile.isOccupiedBy = null;

                    currentTile = tilePath[tilePath.Count() - 1];
                    currentTile.isObsticle = true;
                    currentTile.isOccupiedBy = this.gameObject;

                    tilePath.Remove(tilePath[tilePath.Count() - 1]);
                }
                return;
            }
            else
            {
                FindNewPath(tilePath[0]);
            }
        }

        float distanceToCurrentTile = (currentTile.position - transform.position).magnitude;
        //Same variable name as above. 

        if(distanceToCurrentTile < 1)
        {
            transform.position = Vector3.MoveTowards(transform.position, currentTile.position, Time.deltaTime * moveSpeed);
        }
    }

[knotty sun]

because a variable in an inner scope cannot have the same name as that declared in an outer scope

[candid trench]

wut, is that a C# specific thing?

[knotty sun]

no it is a C language specific thing

[candid trench]

really? I felt pretty confident that it's allowed in C++

hm. strange. i must be remembering it wrong then.

[teal shard]

hello, good day to all of you. I have a problem. Its with Unity Package Manager. Whenever I start a new project there is ALWAYS A error: One or more packages could not be added to the local file system I am desperate. I reinstaled Unity 2x time but nothing. Please help

[candid trench]

worked like a charm btw, thanks

[plush grove]

Hello, I wrote a mod for a Unity game that has basic level of mod support ( they provide the injection for my DLL etc). Currently I have a IMGUI ui that I am looking to move to Unity's UI system. I made an Asset Bundle that has prefabs for a Canvas/buttons etc for my new UI and can load that bundle in without issue. I have also setup the scripts for the button/canvas to create the proper game objects, that I add to a root GameObject in my mod. What I'm failing to understand is how would I attach my GameObject/Canvas to the actual UI within the game so it will appear on screen? Right now setting Active "works" in that my debug log will show everything being setup as I'd expect but it isn't visible on screen

[karmic stratus]

Anyone know what this error means? I looked it up on google but still have no idea what it means. I think it's probably an error in my serialization which is here:

[System.Serializable]

    public string phonetic;
    public string[] phonetics;
    public string origin;

    public string partOfSpeech;
}

Also, here is the API text:

[scarlet bane]

Does this mean checking collisions?

[knotty sun]

phonetics is obviously not a string array

[karmic stratus]

Well there is phonetic and phonetics

"phonetics":[{"text":"/əˈmɒŋ/","audio":"https://api.dictionaryapi.dev/media/pronunciations/en/among-us.mp3","sourceUrl":"https://commons.wikimedia.org/w/index.php?curid=718864","license":{"name":"BY-SA 3.0","url":"https://creativecommons.org/licenses/by-sa/3.0"}}]

[late lion]

I would recommend testing your approach in Unity. Create a scene that has a similar UI setup as the game you're modding (to the best of your knowledge) and use that to figure out what steps you need to take to get your Canvas to be visible

[knotty sun]

phonetics":[{"text"
phonetics is an array of objects not strings

[late lion]

Yes.
https://forum.unity.com/threads/profiler-physics2d-findnewcontacts.611584/

[karmic stratus]

oh ok, so should I write it as

public object[] phonetics;```
or just remove it entirely?

[knotty sun]

what you do is to learn how to define json.

[scarlet bane]

Is their anything i can do to stop large amounts of collision from lagging

[plush grove]

When running in the editor my Canvas is visible, as are the form elements. I suspect I need to set its parent within the mod? I was under the impression just activating an Instantiated canvas would trigger it to show up based on position etc

[late lion]

What Render Mode are you using?

[plush grove]

ScreenSpaceOverlay

[knotty sun]

there are lots of websites where you can paste in a json string and they will generate C# classes for you. maybe you should google for one of them

[late lion]

Have you tested what happens if you have two Canvases active at the same time? Does it work as you expect?

[plush grove]

You mean within the Editor?

[late lion]

Yes.

[scarlet bane]

Is their anyway to make a large amount of collisions around 500ish not laggy?

[leaden ice]

1. If this is the entirety of your JSON then it is not actually a valid JSON file. JSON must start and end with { ... }
2. You need to create a class structure that matches the structure of the JSON if you want to deserialize it.

[karmic stratus]

Thanks, does this seem more reasonable?

using System.Collections.Generic;

[System.Serializable]

public class Definition
{
    public string definition { get; set; }
    public List<object> synonyms { get; set; }
    public List<object> antonyms { get; set; }
    public string example { get; set; }
}

public class License
{
    public string name { get; set; }
    public string url { get; set; }
}

public class Meaning
{
    public string partOfSpeech { get; set; }
    public List<Definition> definitions { get; set; }
    public List<string> synonyms { get; set; }
    public List<object> antonyms { get; set; }
}

public class Phonetic
{
    public string text { get; set; }
    public string audio { get; set; }
    public string sourceUrl { get; set; }
    public License license { get; set; }
}

public class Root
{
    public string word { get; set; }
    public string phonetic { get; set; }
    public List<Phonetic> phonetics { get; set; }
    public List<Meaning> meanings { get; set; }
    public License license { get; set; }
    public List<string> sourceUrls { get; set; }
}```

same error though so probably not

[leaden solstice]

Unity JsonUtility cannot deserialize root array

Use actual Json serializer like Json.NET

I have the ads mediation package installed, but I can't see the settings for it

I don't think I understand what you are trying to accomplish with the test? I'm not bringing the entire video game elements into Unity editor... I'm just trying to launch my custom UI at runtime from my mod's dll - it's very easy with IMGUI, but I'm not understanding the complexity of the newer UI elements

The #1062393052863414313 won't let me post my question for some reason. Can someone help me here?
There is no support for Animation in Entities 1.0.0 yet? Current latest install via PM is 0.9.0. Are there patches/workarounds out there for this time being? I just need to import a rigged model into ECS so I can attach PhysicsJoints to its bones so I can get some physics-based animations going.

[lucid valley]

There is no support for Animation in Entities 1.0.0

I think the current way is to use companion gameobjects for animations

[verbal grail]

Ooof, any news on an ETA? Seems they went quiet again.

[lucid valley]

Pretty sure they said they'll start work after 1.0.0

So could be a year away

we just dont know

[verbal grail]

alright. thx

In DOTS/ECS, when adding a skinned mesh from a rig setup, it creates SkinMatrix buffer to the holding entity. Any way to tap into that and manipulate it's "bones" to get the mesh to deform at runtime? I'm on Entities 1.0.0 atm.

hey guys, can someone help-me?
I'm building an application in unity, and I need to get a 3d object from a website.

    private IEnumerator AddObjectById(int id, string name) {
        string url = GlobalStateData.getInstance().ServerAdress + "bundle/ObjectBundleController/" + id;
        
        UnityWebRequest get = UnityWebRequest.Get(url);
        yield return get.SendWebRequest();
        if (get.result != UnityWebRequest.Result.Success) {
            Debug.Log(get.error);
            yield return false;
        }
        else {
            AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(get);
            GameObject obj = (GameObject)bundle.LoadAsset(name);
            _place3DObjectRef.ArPrefabs.Add(obj);   
            yield return true;
        }
    }

the function always stopping in return get.SendWebRequest(), do someone know why?

[regal heron]

horizontal = Input.GetAxis("Horizontal") * turningSpeed * Time.deltaTime;
transform.Rotate(0, horizontal, 0);
vertical = Input.GetAxis("Vertical") * Speed * Time.deltaTime;
transform.Translate(0, 0, vertical);

I have a code like this, how to limit the rotation of the cube when moving?

[leaden ice]

don't use transform.Rotate, it's additive

you'd have to track and drive the rotation yourself in a float and clamp that

[knotty flower]

I dont know what to do guys, I have read the documentation, watched videos but all this research has made me confused. My weapon snaps to the points, it doesnt move smooth to the points.

        Vector3 localPos = new Vector3(0, 0, 0);

        if (Input.GetKeyDown(KeyCode.Mouse1) && isEquipped == true)
        {
            // Move to aiming Position
            transform.localPosition = Vector3.Lerp(localPos, aimPos, 1);

            Camera.main.fieldOfView = 55;
            aiming = true;
            indicatorIcon.SetActive(false);
        }
        if (Input.GetKeyUp(KeyCode.Mouse1) && isEquipped == true && aiming == true)
        {
            //Move Back to Hold Position
            transform.localPosition = Vector3.Lerp(localPos, aimPos, 0);

            Camera.main.fieldOfView = 60;
            aiming = false;
            indicatorIcon.SetActive(true);
        } ```

[leaden solstice]

Do you know what Lerp does

[clever spade]

@knotty flower Vector3.Lerp(localPos, aimPos, 1); you are lerping to the value of 1 it will always be point b in terms of from point a to point b
