[cold parrot]

what you say there is the global access issue

[misty drift]

I mean that unity a bit fragile regarding configs in editor.

[cold parrot]

using a DI container to solve that is maybe a bit off the side.

it also doesn't solve it entirely, you loose all static code analysis regarding dependencies

[misty drift]

may be u right, I don't have much expirience with Unity. And generally guides/tutorials doesn't go too deep on design. So try and error is a way for me at the moment.

[misty drift]

There is a tool to check dependencies in Unity configured in editor?

[cold parrot]

what do you mean?

you can check for missing references.

[misty drift]

I mean i see if I run program and I can check manually. Is there way to do it automatically?

maybe I'm misunderstanding smth

[cold parrot]

personally i think many ideas from DI are very valuable, i just don't like to have a framework dictate which ones we use in a project 😉

[cold parrot]

you can make an editor tool that checks for missing references, or get Odin Validator

what i like to do is make static editor references for everything thats part of a scene and use a service locator (basically a container) to lookup the managers/systems that any dynamically spawned objects belong to, register themselves with that manager and have that manager manually inject the dependencies OnRegister.

i find the ceremony that creates strikes a balance that it makes people think of how they want to organize their systems and offers sufficient resistance to "just inejct one more thing" while also making it easier to setup, debug and robust.

if you pair that with asmdefs for all primary systems and design your systems in a layered way, the project can partially self-guide a developer to a correct solution by offering a path of least resistance that we actually want to take.

[misty drift]

yep, I tried to do it with asmdefs, but it's too much for me for now - i spent a lot of time on design, while not having enough expirience. as a result I had a lot of code to support design, but had very few fetaures) As of now I'm going with "go fo features" and "refactor when it's needed". Since I'm doing sorta pet project myself, it works for me. for bigger projects focourse it wont work)

But you right, I need to be more carefull with injections, since it becomes spagetti quite fast.

[low scaffold]

Is there a way to access the C# 10.0 file-scoped namespaces feature in Unity? Would like to make use of namespaces for my current project, but adding an extra layer of indentation is a bit aggravating.

[steady bobcat]

no because unity uses an old version of mono

[quaint rock]

unity 6 is on C#9 feature wise but also is missing a few features

also namespace per file is more namespaces then i would want, and would not worry about 1 extra indentation level

[night harness]

i dont know if "don't worry about it" is a valid response to someone's problem lol

[chilly surge]

IIRC file scoped namespace is a compiler feature not a runtime feature, so you could get it to work in Unity by patching the compiler binary to a higher version

But eh, I wouldn't recommend it.

[cold parrot]

yeah, it can be a mistake to design too much when you don't actually see the actual problems yet, you end up with lots of clean systems that do nothing, but conform to all the buzzwords. I certainly did that for years. Its a problem to solve all in itself.

[agile axle]

Hey folks! Have run into quite the doozy of a bug, and there's nothing online I can find to help.

We have one user who is experiencing a crash just after opening our program. The issue is a StackOverflow exception originating from the Cursor.SetCursor() function.
This works on thousands of other devices, so I assume it's something specific to the user's machine that's causing it. If anyone has any ideas on how to troubleshoot this one, it would be mighty appreciated.

Stack trace below:

[leaden ice]

Certainly looks like a bug in System.IO.FileSystem.UnityDeleteFile

Perhaps isolated to whatever hardware or operating system version the user is on

Do you happen to have those details?

[agile axle]

All I've got is that it's Windows 11. It's a very low-tech-skills user, so stepping them through the process of getting more detailed system specs will be a challenge

[hexed pecan]

Why does FileSystem have a unity-specific class/method 🤔 (I don't really know how these things work)

[leaden ice]

I think IL2CPP implements a whole bunch of low level C# stuff in its own way

[hexed pecan]

🧙‍♂️

[steady bobcat]

Im not sure how it would go from kernal 32 back to File.Delete() 🤔

well you can view the il2cpp generated src from a build so that may reveal some info

[agile axle]

It's a mighty weird one for sure.
It's a mono build. Would probably need to bust out a decompiler to view the source

[steady bobcat]

oh mb i presumed il2cpp. You can use something like ilspy to view a nice decomp of the source to see what this function does

managed mono only, if this is a call to native engine code it wont help much

[agile axle]

s'all good 🙂 Sounds like it may be the way to go.

[steady bobcat]

where I work moved to enterprise so soon i get to view the unity source which sounds useful for stuff like this 🧠

[agile axle]

It's been tempting to grab it. Worried about being locked to a specific version though. The ~20k price tag is a lot as well 😛

[steady bobcat]

yea i know it can be expensive. hopefully you can figure it out without

[agile axle]

Fingers crossed. Worst case, a refund for this extremely rare bug is cheaper

[dense pasture]

there a way to correct that tilt? thats the general camera perspective (static camera) and it's getting noticable tilting. Whats the correct math here? google-fu failing me. maybe its the shader i'm using (distance field)

(line 105 is where its facing the camera), dont think the rest is having any effect here but just in case

[leaden ice]

you want it to look not at the camera but at the nearest point on the camera's plane sounds like

So you could do this:

Transform camXform = Camera.main.transform;
Plane camPlane = new(camXform.forward, camXform.position);
Vector3 lookAtPosition = camPlane.ClosestPointOnPlane(tmp.transform.position);
Quaternion rotation = Quaternion.LookRotation(lookAtPosition - tmp.transform.position);
tmp.transform.rotation = rotation;```

[agile axle]

I think it's just a function of having a perspective camera. It looks tilted because of the angle it's on

[dense pasture]

The tmp is set to orthographic

[dense pasture]

Lemme try that

[agile axle]

Is it on a worldspace canvas?

[leaden ice]

but the camera is perspective

[agile axle]

What you'll likely need to do is figure out the apparent rotation of the text in the axis from the camera to the text, then rotate the text around that axis so that it appears straight.
I'm about to head to bed, so I definitely don't have the mental space to figure that code out

Since it's facing the camera already, you're basically just creating a W axis along that Vector and rotating the text around it

[dense pasture]

ah yeah that does it. although its backwards

easy fix

Quaternion rotation = Quaternion.LookRotation(tmp.transform.position - lookAtPosition);
just had to reverse that line

[leaden ice]

Yeah since it's really the back of the TMP you need to see

[blissful bay]

Anyone have much experience with Unity Terrain & Trees? I have an open world which contains a very large amount of trees.
I'm adding "destroying" to the trees. But currently I have to map every tree on game load into a spatial map, then when a player tries to break a tree, do a lookup find the tree index ect.
Then when they actually break it, I have to swap out the prefab index, to a "hidden" tree (blank prefab effectively)
Then I have to swap collision on and off for it to recalculate my new prefabs collision (if i don't do this the old trees collision remains)

Is this a poor design choice? Should I be using game objects for trees, not terrain data. Then despawn them far from the client? (I have a server that I've mapped all terrain trees so that I can send tree information to the clients given they are close enough)

The other solution I thought of was a hybrid approach where I keep the trees on the terrain but disable collision, and spawn box colliders over the trees.

I'm finding some conflicting information from what i've read. Curious if anyone has ever dealt with this. Thanks!

[agile axle]

IIRC Unity's terrain system is rather inefficient. Gameobjects with occlusion culling and LoD/fading out at distance with box colliders should be very performant

I'd probably go the gameobject route personally. Also gives the option for further functionality that the unity trees system can't provide

[blissful bay]

awesome, we will probably go that route then. And yeah that was kind of also what I was thinking, what if I wanted to add a tree falling animation. I'd have to like spawn a game object over the terrain data before i swap to the hidden prefab. Gets very messy

Thanks for the info!

[cold parrot]

It’s inefficient memory wise and has a weird API, the problem is not its rendering/auto-lod within the constraints of that.

[latent latch]

Oh uh. I thought it was the other way around. The terrain provides a brush to instance the trees while removing the overhead of using gameobjects

Makes sense to make them GOs if you are destroying them though, but then you need to compare batching all of them vs chunking

[mossy shard]

How can i stop a 2d object from rotating? When i change it's linear velocity it tends to rotate on the z axis, and when i set from code it's rotation to always be 0 it's twitching

[latent latch]

Rigid body? You can lock the axis

[mossy shard]

damn

i really am dumb

thank u

[sick hawk]

hey yall, I have this script

using EnemyNun;
using UnityEngine;


namespace EnemyDummy {
    public class DummyController : EnemyController<DummyController> {
        
        public GameObject prefab; //respawn yourself when you die
        public Idle idle;
        public Death death;

        private void Start() {
            SetState(idle);
        }

        public override void OnDeath(HitData data)
        {
            base.OnDeath(data);
            SetState(death);

            Invoke("SpawnNew",1);
        }

        void SpawnNew() {
            Instantiate(prefab);
        }
    }
}

and im having a weird issue. When a dummy dies I want it to respawn a new version of it. I have made a dummy prefab, set the prefab reference to that prefab, and placed one in the scene. However, when I run it, it immediately sets the prefab to itself, the scene instance, rather than the actual prefab. This is not what I want because then it spawns a glitched out dead prefab. Is this normal? is unity just being weird? Or is this some stupid thing where unity can't tell the difference between a prefab instance referencing the prefab and referencing itself

since the prefab DOES reference itself maybe its just like

assuming thats what the instance is doing

ive been directed to this https://discussions.unity.com/t/prefab-with-reference-to-itself/631334

[night harness]

Yeah Unity does like convert refs to self prefab assets to the instance of itself

unfortunately

the same way components on the prefab reference the instance

[lean sail]

Ah I was replying in #💻┃unity-talk about that. I completely forgot the reason that issue exists is because other components need to reference the spawned instance rather than the prefab's component

[night harness]

Makes sense but it's a real shame there isn't a solid, streamlined solution to it

[sick hawk]

I guess that makes sense, even if that behaviour on a gameobject is really pointless

idk how it would work but maybe a PrefabReference container or something would work

thats kinda hacky too idk

[night harness]

its not how it works but ideally would be great to just have some attribute we could use to mark stuff to not like transfer

[sick hawk]

oh an attribute would probably be best yeah

[lean sail]

in your case, i dont know if you'd have an external object that could store the reference to the prefab. Maybe doing it through a scriptable object is simplest

[sick hawk]

imma make a dummy spawner script and hope I never need to solve this issue again

[steady moat]

I usually use a "Definition"/ScriptableObject to spawn my objects.

[night harness]

I don't think it's a solution but in theory it is possible to iterate through the prefabs and compare object names but blahh

[steady moat]

Which does not have the issue, you might want to use the same strategy here.

[lean sail]

in the link that i sent (that willow resent in this channel), there are solutions that use like Resources to solve it. Its just definitely not what anyone would wanna do

[night harness]

I didn't mean resources

[steady moat]

It helps in the event that you need to reference the "meta" object. I.E. the name, description or other settings that should live without an instance of a prefab.

[night harness]

iirc you can iterate through the scene objects in the hideanddontsave scene which will be the currently loaded prefabs in memory

string comparison still yucky but a abit more controlled since both comparison points are established during runtime yknow

[lean sail]

🤷‍♂️ never really heard of that myself but either way that's still not what anyone would wanna do. just putting it in a scriptable object would be miles better

[night harness]

SO in a lot of cases is probably preferable yeah, But there's reasons I've found to at least be interest in that approach though

[lament wasp]

hi yall, I'm making a character controller but im having issues with the camera, this is what it looks like and this is the code, otherwise nothing really impacts the cam
https://cdn.discordapp.com/attachments/493511037421879316/1354981561967050896/2025-03-27_18-52-12.mp4?ex=67e7446a&is=67e5f2ea&hm=10776bccd5a522ad73258d787ed5e883e4a1d9e7e4a22f1b84a925de9cc8d4af&

The issue is NOT time.deltatime

[lean sail]

https://unity.huh.how/mouse-input-and-deltatime it most certainly is part of the issue at least

also, use cinemachine and you dont need to make your own camera controller

[lament wasp]

Just stumbled onto this outside of here and yeah it's probably the best option

[latent latch]

immma take a guess and say you've got it parented and you're trying to override the rotation but it's fighting

[lament wasp]

i've used cinemachine before idk why i didn't think of that

thanks

[lean sail]

yea that setup of setting the rotation of 3 things looks questionable

[shadow wagon]

I'd also suggest debug log the two xyrot values, but cinemachine is the better choice

Were you calling the function inside FixedUpdate?

[lament wasp]

no

[unkempt bloom]

Should I be learning Unity 6 or is 2022 still more stable?

[vestal arch]

they're overall pretty similar

2022 is probably slightly more stable? 🤷

[unkempt bloom]

I'm assumming there's more tutorials around the 2022 version? or are they similar enough to the point where those tutorials should still apply?

[quaint rock]

there is not that much different

mosty 20xx stuff will apply just fine to 6

[soft shard]

There might be a few parts of the API that have different naming for some things in 6 compared to 2022 (for example, rigidbody .velocity in 2022 is .linearVelocity in 6 for reasons), and there might be some visual changes but functionally 2022 tutorials should work fine in 6, even older 2018/early 2K tutorials should largely be fine too

[unkempt bloom]

Got it. Thanks! Would you say that most have switched to 6 by now or is it still fairly new?

[soft shard]

For some devs, its not uncommon to have multiple Unity versions installed for various projects, some ongoing projects might find it better to stick to a particular version instead of dealing with the possible issues that can happen with upgrading/downgrading a project, some devs use different versions to support older assets, some may even just want to try out the newest features, others may see no reason in using 6 for technical or other reasons, but unlike OS updates, Unity versions are one of those things you dont absolutely NEED the latest version, you can use any version for as long as you want (albeit, some versions may have LTS (Long-Term Support) updates and others are "as-is" so any issues with non-LTS versions will not get patched in the future)

[modern atlas]

I'm using 6 and it works just fine

[fierce cargo]

I have a question. Has anyone been able to integrate unity level play into their project without issue?

I would consider myself a competent fledgeling game developer. But, I have never encountered a more challenging task than this. I have endured four days of agonizing troubleshooting and I am still incapable of getting ads to run on my game

I tried rolling back to the legacy ad system and just kind of forgetting about using a mediation system

But, I am still getting these stupid windows32 errors where the android dependency resolver freezes. Then i put the gradlew.bat file into the temp folder like internet forums suggest. Then it starts resolving but then fails again. Im dealing with such significant frustration from this that I am starting to doubt myself and my skills even though I have been coding for well over three years now

Sorry. I'm aware it's inappropriate to vent my frustrations like this on here. Honestly, I am just looking for some help from a more experienced developer

Maybe this is a sign to shift my monetization strategy away from advertising lol

[shadow cradle]

has anyone used the firestore sdk? im having problem with the constructors. they are being called twice in deserialization and after Start()

[undone prism]

Could anyone help me with my problem? I am making a carcontroller and want to use my own system (so not using unity's wheel colliders). In the Wheel script it seems to go wrong but I cant find why. It starts wobbling side to side when on low speeds. I think it could maby have something to do with unity's way of calculating physics but im not sure, maby im just doing something fundementaly wrong.

Wheel script: https://paste.myst.rs/lz3oz71v
Suspension script: https://paste.myst.rs/osd53mbd
WeightDistribution script: https://paste.myst.rs/dklxwo3a

Here also a small video of the problem. The green lines are the velocity of the main rigidbody and the red stripes are the suspension force.

[wide totem]

How can i go about playing an animation in reverse from its current frame, as in, if its halfway through, it will start playing backwards from that halfway mark.

[vestal arch]

why not make it half as long and ping-pong it?

[wide totem]

i mean thats kinda what im trying to do, but from any frame

[hexed pecan]

Hmm you probably need to do it per-state with AnimationState.speed

Or use a float parameter and use it as a speed modifier for all the states you want to be able to reverse

[vestal arch]

ah, "half" was an example, mb.

[vestal arch]

use .mp4 so it's embedded in discord.

convert it online or something

[vestal arch]

(btw, why not unity's system? did you have issues with it, or do you just want to make your own for learning purposes?)

[hexed pecan]

I don't see anything wobbling except the green lines

They appear wobbly when the velocity is near zero and you are normalizing it

So I don't think it's an issue really?

If it actually has some physical issues you can try smoothing/damping the forces somehow so it's not as jittery

[undone prism]

thats exactly the problem. The velocity is inconsistent. the car doesnt stand still in the example so ill send another video but it really is a problem

[vestal arch]

it doesn't seem to actually be deviating from the path though. have you tried not normalizing the vector? do you still notice the wobble then?

[undone prism]

here you can see the problem better. i prefer not smoothening the grip since it isnt going to feel right but rather floaty and the requirements i got was explicitly not to make it floaty. any other sugestions on what could solve it?

[undone prism]

yes i tried not normalizing it and it didnt really make a difference.

[vestal arch]

ah i see.

what about just damping the speed?

[undone prism]

in what way would i be able to damp the speed?

you mean the velocity?

[vestal arch]

yeah

[hexed pecan]

Btw, I see you moving the wheel in Update.
Better keep its visual as a separate object and control its position in update, and control the physical wheel in FixedUpdate instead

[vestal arch]

if you have a dynamic rigidbody, you could apply damping/drag on that

[hexed pecan]

Otherwise you introduce framerate dependency here

I was thinking you can damp the individual forces of each suspension point over time, to avoid harsh movements

[undone prism]

so you are saying the clamping of the wheel should be done in the fixed update?

[hexed pecan]

Yeah. Pretty minor thing, but thought I'd point it out

[vestal arch]

physics should be done in fixedupdate in general

[hexed pecan]

You generally don't want anything in Update affecting stuff in FixedUpdate

Except for some inputs ofc

Not a minor thing now that I think about it

[undone prism]

i get what you mean, minor mistake. it didnt solve the problem tho. i also tried to do some things with the built in dampening of the rigidbody but it doesnt seem to make a difference

[vestal arch]

is it dynamic or kinematic?

[undone prism]

dynamic

[undone prism]

yeah when you mentioned it i was already thinking how stupid it was XD

[hexed pecan]

^Talking about Suspension.ApplyForce here

[undone prism]

i dont know if thats the problem tho since the suspension worked perfectly before the wheel script was made. i did add anti roll bars in after posting here that should effectively do a similar thing and i hoped that would maby solve the problem since it was another kind of dampening in the system but it didnt seem to help.

i have a feeling this problem might be a bit harder to solve than a dampening factor. i hoped i maby made a small mistake in coding it and somebody would maby find it here. i have already searched for hours on the internet and got experienced coworkers check it but nobody seems to find the problem

[hexed pecan]

Does it happen if you disable UpdateLateralGrip?

[undone prism]

if it helps to mention i am at unity version 6000.0.40f1

[hexed pecan]

You can also see physics settings like "default velocity iterations" or a smaller fixed timestep to see if it's just a physics instability issue. Doubt it tho

[undone prism]

no it doesnt. when i turn UpdateLateralGrip off it only slides off the ramp but all the suspension dampening is really smooth

[hexed pecan]

So your issue is somewhere in there

[undone prism]

yeah, i dont know where tho

[hexed pecan]

I'd try damping that but you seem really convinced that it's not a damping issue

So 🤷‍♂️

[undone prism]

i made a script in a 2022lts about a year ago doing the same thing but with a calculation in velocity instead of weight on the tyre to calculate it and that worked fine but the system used colliders which i cannot for this project. i also cannot change any physics settings because it has to go into a really big existing project.

[hexed pecan]

Yeah, using physical colliders for wheels sounds like a pain

[undone prism]

i dont know but i got the instructions to make it feel great and since i have made some similar stuff in the past i am relatively certain it wont feel like they expect it to

i was thinking it might have something to do with the way it is applied and stuff like that but i have already tried a lot of stuff that didnt work

[hexed pecan]

I feel like you should scale the slip force with your current speed

[undone prism]

chatgpt has told me it might be floating point errors but it seems so extreme for floating point problems. it already starts doing it at around 1.5 on the velocity.magnitude

[undone prism]

i could maby look into this. i have lunch break in 5 minutes but ill certainly check that option

[uneven mortar]

does anyone know how to fix this??

here's the code (ignore the croatian comments, this is for school)

i have more scripts but i believe this one's the one that needs tweaking

[hexed pecan]

This script spawns pipes on its own position (with a random Y offset).
So you should move the object that has this script, to the right

In the editor

[uneven mortar]

omg thank you!

[wide totem]

"this behavior" refers to the instance of the script right?

[rigid island]

the keyword this ?

[wide totem]

behaviour

like for stopAllCoruntines()

its all of them in that instance of the script yes?

[rigid island]

On the Monobehaviour script

yes

[wide totem]

thank you

[thorny rock]

Cool stuff! It looks like either floating precision error or because you are not using the physics system, the steps are calculated faster and thus the camera (Who's probably following it in the Update loop, called 100's of times) is getting a small reposition every frame, not physics frame: https://docs.unity3d.com/6000.0/Documentation/Manual/execution-order.html (scroll down for the Script lifecycle flowchart)

Every frame depends on your computer speed and physics frame is ~60 a second. You usually see this kind of behaviour in Unity too when you are following a Rigidbody object with the camera in an update loop (That's why we have LateUpdate, an update after game logic/physics calculations) . Just a thought 😄 .

[stuck dirge]

hello, I'm just getting started in Unity, I have an error or I don't know what it is going to, I want to create a GameManager but when I create the Scrip it does not adopt the nut icon and will not react as it should, I think it is due to an error of the Unity since the same thing happens when creating a new project, I'm on the latest version

[vestal arch]

ok, do you actually have an error? or just an issue in general

[stuck dirge]

It would be a general problem since the console does not show any error in the compilation, when creating the GameManager with Monobehaviur it does not adopt the nut icon, or well I don't know much about the subject

I want to upgrade to an LTS version to see if the error persists

[vestal arch]

i mean, what's the issue there?

GameManager is only special with the icon, it works the same as any other script

[vestal arch]

🤨 if you were on latest you should already be on an lts version

[stuck dirge]

I was not in an alpha. 😑

[vestal arch]

the latest version isn't on alpha

ah well.. the latest as in highest version number is alpha, i was looking at the wrong column

but you really don't need that

just use full releases

[pastel atlas]

Is there any easy way to track variable references when its being passed by reference between methods? As in if I have a variable _position...
A call is being made to MoveCharacter( _position, _velocity, etc... )
MoveCharacter method header is ( ref position, ref velocity, etc.... ) and inside the method it calls more methods which again have method headers where its inputs are being passed with ref keyword.

So a method 2-3 calls deep is making its way back to modifying the variable I really care about _position. I know visual studio has a way to check for references, but only 1 layer deep. It's not tracking if its being passed to more methods by reference. My code base isn't massive or anything so it's not like it would be very difficult to brute force it but I don't know if there's a tool that can do it for me so the human element is taken out of the equation

[soft shard]

Not 100% certain if this is the best way but it is one way you could try - you could make your variable a property and use an observer pattern (event in your property setter) then you can have some debugger script subscribe to that and print the stacktrace, or you could just log the Environment.Stacktrace from the functions your variable is passed, or you could try using breakpoints, I believe in VS you can "watch" variable changes this way

[late lion]

I don't know of a static analyzing tool that does this. It would be possible up to a point; there are also ref variables that can be dynamically set. ref is nothing more than a sugar coating on pointers, which are not trivial to keep track of statically.

[mossy shard]

What does it want from me?

haven't i setted the animator in code or sum

[somber nacelle]

https://unity.huh.how/animation/animation-event/functions

[naive swallow]

You have an animation event that doesn't call any functions. You might have added one by accident

[mossy shard]

so i added an animation by accident?

[naive swallow]

Animation Event

to an animation

[mossy shard]

how do i delete it

[shadow cradle]

is there a way to create curved ui lines?

[rigid island]

maybe the spline tool

to some extend line renderer can also do curved lines but more difficult

for spline you can use it to create a mesh , basically what a line renderer does anyway (its a mesh)

[shadow cradle]

i want to avoid rendering 3d on the ui, the only thing i could think of was connect str8 thin images but then i would get corners not curves

which isnt bad if done right

[rigid island]

what is the exact usecase?
technically the whole engine is 3D. The mesh would be very simple most 2D sprites are just a quad anyway

[shadow cradle]

u mean just put the quads very close to the camera? dont think it will look right. im making a runtime node editor and want curved lines to connect the nodes

[rigid island]

nah.. I was just saying most 2D stuff in unity is just quads.

wouldn't it be easier to make a node editor using something like the Visual Scripting API ?

or now I think unity also put the GraphAPI or whatever

[shadow cradle]

those dont work in runtime unfortunately

althought they may make the new graph tool work in runtime at some point

[rigid island]

hmm I think the new Graphics API did that but i can't find the exact link

[shadow cradle]

new graphics api?

dont think theres such thing

[rigid island]

yeah I'm trying to find it

its what the new Behavior graph uses

ugh

https://docs.unity3d.com/Packages/com.unity.graphtools.foundation@latest

seems down now?

[shadow cradle]

Yea we talk about the same thing

https://discussions.unity.com/t/unity-graph-toolkit-update-q1-2025/1614727/62

Unfortunately its editor only

[rigid island]

balls

could've sworne runtime was mentioned but ig it was another thread requesting it.. unfortunate

the only thing I can think is using Splines, the most straight forward way

there is GL but thats pretty advanced and probably overkill here

Line Renderer / Spline imo is the easiest way

[shadow cradle]

How can this be implemented?

[ionic grove]

Do you guys know how I can get this field's value through code?

[vestal arch]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Animations.AnimatorState-motion.html

[lean sail]

at runtime or for editor code? the above link is under UnityEditor

[ionic grove]

Yeah at runtime 🙂

[lean sail]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/AnimationState.html

its the same name just under unityengine

[vestal arch]

ah whoops

[rigid island]

for Splines you can set up the path / points then put a mesh between those points.
for line renderer you do the same but adding curves would involve some special technique forgot the name, I can find it rq
edit :
there is another one for line renderer but forgot the name
https://www.gamedeveloper.com/business/how-to-work-with-bezier-curve-in-games-with-unity

[vestal arch]

(it isn't)

[lean sail]

(i only read the first 4 letters, the rest is extrapolation)

lol it really looked the same at first

[ionic grove]

Ok I looked at that already but got caught up on how we only have an animation clip and not an animation

[vestal arch]

can you elaborate?

[lean sail]

im confused what you mean by this, the clip is the animation thats playing

[vestal arch]

animationclip -> actual animation data
animation -> component that run animationclips
animator -> component with a state tree to run animationclips

[ionic grove]

Right, the clip is the actual animation. The Animation state is what is holding the speed variable.

[shadow cradle]

Ty, and how can that be rendered in the ui? Hope render texture is not the only way

[ionic grove]

Animation clip

[rigid island]

Set the canvas to Screen - Camera

[ionic grove]

Animation state

Here is my code:

IEnumerator PlayAnimationAndAct(string animationToPlay)
{
    float animationTimeToComplete = 0f;
    float animationSpeed; // Default animation speed

    // Wait until animation done
    if (animationToPlay == "BackUp")
    {
        animator.Play(standUpAnimation_BackUp.name);
        animationTimeToComplete = standUpAnimation_BackUp.length;

        animationSpeed = animator.GetCurrentAnimatorStateInfo(0).speed; // Get current animation speed
        print("Animation Speed: " + animationSpeed);
    }
    else if(animationToPlay == "FaceUp")
    {
        animator.Play(standUpAnimation_FaceUp.name);
        animationTimeToComplete = standUpAnimation_FaceUp.length;

        animationSpeed = animator.GetCurrentAnimatorStateInfo(0).speed; // Get current animation speed
        print("Animation Speed: " + animationSpeed);
    }

    yield return new WaitForSeconds(animationTimeToComplete);

    // Set variables
    SetCanMoveAndLookToTrue();
}

[vestal arch]

@ionic grove what's your question and what are you trying to do?

[lean sail]

you should probably just use that parameter checkbox, then set that float param through code instead

using the multiplier

[ionic grove]

#archived-code-general message

[ionic grove]

Yeah that's an idea. I could just do that

I figured I wouldn't have to because there would be an easy way to get that value, but I guess not

[vestal arch]

ok, but, why exactly? sounds a bit like an https://xyproblem.info

[lean sail]

itll be a lot easier
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Animator.SetFloat.html
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Animator.GetFloat.html

[ionic grove]

Because the animation clip length is longer than how long it takes to complete because my animator changed the speed of the animation state

[vestal arch]

well, no, it's just that length but scaled, and how's that an issue?

[ionic grove]

It's not an issue.... It's just that I'm altering variable values when the animation is done. So the game thinks it's taking "X" seconds to complete when really it's taking "X/Y" seconds to complete

[vestal arch]

why not use animation events?

that way you don't have to deal with time at all, and you would just let the animator handle that

if animation events aren't what you're looking for, then

So the game thinks
🤨 can you be more specific here about "the game thinks"

[ionic grove]

Now that's a better idea

[vestal arch]

ah, so it was x/y problem, lol

[ionic grove]

I think an anim event would work fine here

It was an "Ugh" gif

[vestal arch]

wait were you pointing at motion or speed here lmao

[ionic grove]

Speeeeeeeeeeeeeeeeeeeeeed

[vestal arch]

that makes much more sense to the rest of your questions lol

[ionic grove]

Lol omg

When you linked that Motion doc, I was like.. Bro that's so unhelpful 😄

[vestal arch]

you didn't actually say what you wanted in the message, the arrow looked like it was pointing to motion to me lol

[lean sail]

Honestly not a huge fan of either approach (probably cause I dont fully understand animation transitions) but I do instead try to define stuff like this in code and inspector. The code dictates how long it should take, and tells the animation it, adjusting the speed multiplier

[ionic grove]

Yeah I don't understand how this isn't a simpler process. I don't like the whole set float thing either, but at least then my animator can set it in the inspector

[lean sail]

i do remember having cases where animation events didnt trigger as i wanted it to. also its just a huge pain in the ass to setup

[vestal arch]

since your case seems to be solvable with events, this is just out of curiosity; what did you mean by this?

oh also; timelines are also another option, but iirc that's a pain to make work with animators

[ionic grove]

It meant that the time to complete the animation is now length / speed. But my code just sees length right now, so it's taking too long when the speed is set to 1.75

[lean sail]

well your code example specifically is part of what i meant "huge fan of either approach". yours has hardcoded strings and is reading the value. What i setup in the past was specifically declaring (like on a component) how long it should take, and then adjusting the speed multiplier as needed

[naive swallow]

As someone who has tried to animate things using the legacy animation system - trust me, this is much better. The legacy system was such an absolute clusterfuck you basically couldn't do anything more complex than "Play this one animation straight through at this moment in time"

The current Animator workflow with transitions and parameters is capable of taking so much of the cognitive load off of you it's very much worth learning

You can look at VRChat avatars, every single bit of functionality those have is driven almost entirely by the animator and parameters

[ionic grove]

I believe it. However, I just develop and would like to stay as far away from animating as possible 😆

[sick hawk]

honestly, the animator is your best friend

its useful for sooooo much

it can do very simple functionality quite fast

[ionic grove]

But I'm scared 😆

[sick hawk]

its really not hard!

its basically just a timeline

also animation is fun! you can add a ton of juice just by messing around with animation scale, color, position, rotation

[ionic grove]

But I can't drive myself nuts trying to proceedurally animate things before my animator gets things done then lol

[sick hawk]

sounds like me ~3 years ago

[latent latch]

Animator is sweet but I never get the chance to use it

[naive swallow]

Make Avatars for VRChat, then it'll be literally your only tool and you'll wish you could actually code something in no time

[latent latch]

Really if I didnt have to bloat my project with controllers id use them more over tweens

Vrchat creation does sound like fun though. Need to really figure out bone and cloth physics more

[naive swallow]

It's definitely one of those "When all you have is a hammer" things. But it turns out most problems can be reduced to a series of nails

[vestal arch]

screws are just really detailed nails

tenons? wooden nails

[dense pasture]

Curious, is the visual scripting system possible to leverage in a similar way to scriptable objects?

Case in point: I’m building a suite of “codeless tools” so my team can contribute content without needing to follow c#. In this case I was thinking about a way to build something like a quest storyboard.

Could I leverage visual scripting engine to make that easy to put together or would I be better off making my own abstraction and making custom UXML editor?

I wanted to leverage the graph/node format similar to shader graph

[rigid island]

there's this..but.. https://discussions.unity.com/t/unity-graph-toolkit-update-q1-2025/1614727

third party option https://github.com/alelievr/NodeGraphProcessor

unsupported for non-internal use, untested. But looks cool af
https://docs.unity3d.com/Packages/com.unity.dt.app-ui@1.2/manual/index.html

been trying to do a few tools myself so I've been where you at lol

[onyx dirge]

how do i code a spinning text mesh

[rigid island]

spin in which way? thats pretty vague

[dense pasture]

Which have you settled on?

[onyx dirge]

spin on Z axis

[rigid island]

I haven't had time to try the others, I was going to wait for the new one but meantime use the Visual Scripting graph I think thats what shadergraph used before merge to Graph toolkit ?

[dense pasture]

I don’t need a whole lot of bells or whistles, just a way to use custom scripts for advanced purposes. Yeah I think VS looked close to viable for this

I got the custom scripts support into my cinematics framework but the whole thing is just a linear array editor

Being able to work it up to something like a graph/node based workflow would be ideal

[rigid island]

I think that the most mature of them all and probably easier to integrate as running code rn VS one

[dense pasture]

I’ll have time to explore it tomorrow I’m just not gonna be at my pc all night to see if my theory was right

Thanks for the info

[rigid island]

what have you tried so far ?

also this sounds like a question for #💻┃code-beginner

[wide totem]

do buttons need textMesh attached to work??

[rigid island]

the two aren't related , so no

[wide totem]

i swear my buttons only started working when i gave them a textmesh wth

[rigid island]

well you need some type of raycast target probably why

[wide totem]

oh

[rigid island]

if you put a blank Image component it would work too for example

[wide totem]

does the button shape itself not count?

[rigid island]

the button uses whatever shape the target is

keep in mind Button is just a component, what Unity does for the premade button is just combining the image component with that button component, then TMP Is just a child

[wide totem]

thank you

[wide totem]

why is it displaying white and not the selected color (was set that color in script)

as soon as i edit it at all it turns back to the purple

but like

why is it white 😭

[lean sail]

look at the docs for color. you're probably giving it values greater than 1

Hey everyone, I was just wondering if its a good idea to child the camera to a moving first person character with animations. It works well with 50+ fps but under that(or fluctuating fps) I could notice a lot of jitter and snappy movement of the camera. The only reason I am using this as a solution cuz I want the camera movement to be realistic. Is there any other way I could produce a similar effect. Thank you.

[kind willow]

anyone using the localization package? how can I force it to halt loading locale on game start?
I want to reproduce an error from a webgl build

I am trying to get a localized string somewhere before making sure the localization is loaded

alternatively since I am always seeing 2 errors I can just add debug logs to all my localized strings calls to see at first 2 but I have no idea how to

any visual studio code way to add a new string under all strings containing matching code?

[vestal arch]

find in project & replace?

ctrl+shift+f

[kind willow]

I have like 100 calls

[vestal arch]

im not sure i understand what you want

[vestal arch]

ah, this? yeah find in project & replace could do that

write a regex to match the call you're targetting to add debug.logs

[kind willow]

regex 😢

the issue is that I am using GetLocalizedString not on just it's own but also to build strings

if you say regex can help with inserting code, well, good to know, but I ain't going to this rabbithole yet

[vestal arch]

doesn't sound too hard in this case

if you could show a few examples of what you want to debug, i could write one for you

[kind willow]

I am having 2 use cases for GetLocalizedString(), I either assign text.text = something.GetLocalizedString(); or text.text = something.GetLocalizedString() + "something" + "optionally something else"; ect

either way it's not a huge deal for me to debug manually and those errors are not causing anything bad

I am mostly asking all that out of curiosity to learn how to be handling that properly

[vestal arch]

well this is kinda a bodge, but giving that it's for debugging, it's probably fine lol

[kind willow]

I would honestly don't mind being able to just redefine localization method for getting localized strings to insert a debug into it

this sounds more simple

or as I was saying at the start find a way to make getting localization very slow so errors pop up in the editor

[vestal arch]

what would you be debugging here?

as in, what to put in the debug.log

(also interpolated strings exist, might want to try those)

[kind willow]

well nothing since I just need to see the first 2 calls (hopefully they are the ones causing errors, if not, well, it sucks)

and logs have a bunch of info if you click on them in console

[vestal arch]

^(?=( +).+something\.GetLocalizedString\(\)) replace with $1Debug.Log("call"); //--\n

the //-- is just you can search to remove them later

[kind willow]

looks ominous

[vestal arch]

it really is just "find the thing and put a debug before it"

the $1 is to get proper indentation

this wouldn't work if the statement with the localization were a 1-statement if or something like that though

i wonder if c# has the comma operator one sec

[kind willow]

where do I even type in and execute the regex?

[vestal arch]

in search, ctrl+shift+f

[vestal arch]

so it does, this could be made working with single-statement ifs/whiles/fors if you want

but it'd be harder to remove

[vestal arch]

(this is for your entire project, use the normal find & replace for a single file)

(and you can filter by file extension/name with the 3 dots)

[kind willow]

what does "something" there

[vestal arch]

well that's what you gave as an example of the call to match lol

if "something" can be arbitrary, you can use \w+ for any identifier

[kind willow]

alr I will just give the actual code sample I use
string multiplierString = multiplierPreString.GetLocalizedString() + " x" + currentMultiplerString;

[vestal arch]

is it always multiplierPreString or can it be some other name?

[kind willow]

the point of GetLocalizedString is that you call it for different variables

aka localized strings

[vestal arch]

aight, so use \w+

[kind willow]

you are getting a string.... out of a string

[vestal arch]

right, but i don't know if you're using existing constants directly or if it's in a function where they all end up with the same parameter name

i don't know how specific you want to get lol

[kind willow]

right, was bold to assume everyone know the specifics of this package

anyway I have no idea what do you mean by use

[vestal arch]

ah sorry

^(?=( +).+\w+\.GetLocalizedString\(\)) replace with $1Debug.Log("call"); //--\n

[kind willow]

^(?=( +).+\w+.GetLocalizedString()) something like that not workign

[vestal arch]

make sure you've selected regex mode

[kind willow]

now it works ><

[hexed pecan]

Regex looks so insane to the untrained eye

[vestal arch]

true

if you want a different debug message, just change it in the replacement

it's pretty much plaintext except for escapes \x or replacements $x (for any x)

[kind willow]

well, it worked (also it did find my old code commented away but whatever I take this collateral)

I guess I will have to learn regex at some point

[vestal arch]

ah, forgot to check for that

[elfin walrus]

how can it not look insane
like.. just look at it

[kind willow]

for a moment I thought that the idea of finding and replacing code using vague word descriptions would be a perfect fit for a neural network but then I realized it would botch it harder than people

[vestal arch]

brief explanation:
^ is an anchor, it matches the beginning of a line
(?= ) is a lookahead, it checks the following text without matching it
( ) is a capture group, it captures whatever it matches to be used later (as \1 or $1, since this is the first capture group)
+ matches multiple spaces. ( +) is used to grab the indent depth (though should probably be ( *) to handle unindented code; + requires at least one)
. matches any character other than newlines, .+ matches a section of any character (this should probably also be .* to handle the general case)
\w is any word character, aka a-z, A-Z, 0-9, and underscores. \w+ is a section of any word character, to match an identifier.
the rest is literal matching, \., \(, and \) are escaped to avoid regex features
the entire regex matches a 0-character string that's followed by the call in question; specifically, it's at the beginning of the line
i'm using a lookahead here to not match the call in question, so we don't have to add it back in when doing the replace
since it's at the start of the line, and the replacement ends with \n, this basically adds another line before the targetted line
$1 in the replacement grabs the first capture group, the indentation depth, then the rest is literal

[kind willow]

I have already peeked regex symbols and get scared, you don't have to project my phobia here too

[vestal arch]

for a detailed explanation, copy the regex into https://regex101.com

[lean sail]

Quite literally half of it is to denote stuff like how many occurrences of a character you want, and backslash for special characters or predefined groups \w being for words
It's really not complicated to use. In most cases, if you're using it in a really complex way, it's the wrong way to be doing something

And yea regex101 is a must use tool. It describes it step by step

[vestal arch]

then you get to the weird stuff like matching emails 😆

or valid dates, accounting for leap years
or emojis, including combining emojis

[lean sail]

In the problem of matching emails, it's gotten more accepted to go with the naive approach

Because there are a lot of cases where a solution is proposed and whoops one user suddenly doesnt work

[vestal arch]

hey, i never said practical stuff lol. just weird 😆

ah man there's probably a regex for urls with punycode support lmao

[lean sail]

True, what I said above also kinda addresses the whole issue of regex. Like it's usually just a waste to validate everything with regex when its miles easier just directly in code. Leap year being just math

I've always found it weird when people who learned it claim regex is insanely hard. There is almost always an easier alternate solution

Not directly talking about the case above cause that actually requires regex for the built in search

[kind willow]

I only heard bad things about regex so I am withstanding to learn it so far

also this is like the first time I have encountered a need for it

[lean sail]

I've used it in the past in similar conditions, mass editing text in my ide. If you learn the absolute basics of it, you'll be able to play around in regex101 and get the result you want

[kind willow]

no wait ti's the second time... first time I just went for manual editing like 30 times

[lean sail]

I'd assume that's mostly comments from people studying it in uni, or people just repeating it cause haha funny. The basics of it is simple, and then complex regex is almost never needed. Even then a complex regex is just a combination of a bunch of simple regex

[kind willow]

complex code is just a combination of a bunch of simple code

[shadow wagon]

biggest downside to regex is it limits who can help troubleshoot it

I suppose thats the case for all programming languages

[vestal arch]

well, it's opaque. hard to debug if it doesn't work
unless you have a dedicated debugger like on regex101, but that doesn't always help. it's kind of an esoteric system

it is just a state machine, but damn is it a complicated state machine

[shadow wagon]

benefit of it being esoteric is you get bragging rights!

[naive swallow]

Once I tried writing a regex and I accidentally summoned a demon instead

[vestal arch]

normal occurance tbh

just make sure it's not the html demon

[chilly surge]

It is quite convenient for simple stuffs, but for complex stuffs regex code basically becomes read only.

[gray cloud]

Not sure if mentioned here, but Regex is one of those things that language model AIs are pretty good at. They can both break them down to explain them but also construct them. Something with how regex is a pattern system and AI excels at patterns. Might be a useful tool for debugging them too.

[chilly surge]

https://regex101.com better.

[gray cloud]

You would of course copy it to regex101 to test it, they aren't mutually exclusive tools, rather complimentary ones

[vestal arch]

regexes are more finite than code, probably just more examples to directly copy

but still, nowhere near a guarantee

besides, different flavors and newer features exist

[open plover]

Can you check if the phone is using dark mode

[rigid island]

there isn't any built in unity method afaik. you can probably easily call the native scripts though to do so

it will probably be wayyy wasier for android

[vestal arch]

https://stackoverflow.com/questions/75910873/how-can-i-detect-android-dark-mode-in-unity

[rigid island]

oh there ya go lol

[open plover]

Chatgpt says “If you’re using Unity UI Toolkit, you can detect dark mode in Application.theme”

I guess they implemented it in newer versions

[rigid island]

is not possible GPT invented something ? seems the usual for me

[dusk apex]

The newest api doc for application
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Application.html

[open plover]

Yea seems like chatgpt made it up

[rigid island]

not surprised

[steady moat]

regex is actually pretty simple when you understand the base.
There is mostly only 4 symbols, every other are a combination of them.
( ) (Grouping), * (Kleene Star) , ⋅ (Concatenation) and | (Union). The theory come principally from finite state machine.

[vestal arch]

what flavor of regex is this

this is definitely not typical regex

i don't know of any flavors that use the middle dot

i think you're talking about a different kind of regex? in cs?

[steady moat]

The middle dot is the formal notation of a concatenation in formal language which regex come mostly from.

[vestal arch]

yeah, in formal language. regex doesn't use it

[steady moat]

Obviously, that is beside my point.

[vestal arch]

it's not really obvious. it seems like you're talking about actual regex, especially when you say there's only 4 symbols

the perceived complexity in regex comes a lot from how many special symbols there are

[steady moat]

It would be more accurate to say that there is mostly 4 operator.

[vestal arch]

sure

[steady moat]

It is way simpler then it seem because most of the symbols are a quicker way to write the operation I just said.

[vestal arch]

tbh though, i think for learning just to use regex, using the regex terms would make more sense
sets, quantifiers, anchors, and groups

[empty elm]

does Physics2D.CircleCastAll find colliders that are inside (not intersecting) the initial circle? If so is it because it is able to detect points inside the circle, or it notices the collider intersection as the shape exits the circle that is being dragged

[leaden ice]

OverlapCircleAll is an instaneous circle-shaped check

ther eis no such thing as the "initial" circle

or things "entering" or "exiting"

[empty elm]

whoops I meant circleCastAll

[leaden ice]

Yes 2D raycast and raycast-like queries detect colliders that overlap the start of the cast

what in the name of all things magical causes unity to register clicks somewhere other than the button? 💀

I'm building a menu for my VR game

for reason's i can't begin to fathom, The click is not being triggered on the button, but below it.... it's as if the trigger area didn't resize/move with the Rect Transform 🤔

in the video is a bog-standard UI button, which is a child of a world canvas (sorry, I'm so new at game dev i don't even know what to offer in the way of context)

I could do with some help here This is a bug in Unity.... the issue is not there when you build and run the game

[rigid island]

#🥽┃virtual-reality

pretty sure world canvas is still not a thing for VR. isn't it ?

[next isle]

I meant world space

[rigid island]

oh okay

Im confusing it with something else lol I dont touch vr

[next isle]

understandable

bloody nightmare having to put on/take off/recharge my headset every 5 minutes

[rigid island]

yah for me its not having it a headset, maybe you need a special type of Input module, I have no idea

[next isle]

I'll forward this on to #🥽┃virtual-reality my bad for missing it in the list 😅

Using ScriptableObjects as a basis for an inventory/item system is common in Unity, but how do people deal with it when item state is mutable and needs to be persistent? For example if items have a bunch of stats on them that need to be saved.

[tired shore]

void Start() {
     MyItem = ScriptableObject.Instantiate(MyItem);
     MyItem.DamageStat += 10; // this only changes this local runtime SO, not the base on in your project
}```

Create a clone you can edit without affecting the original base stats.

That said, I've kinda fallen out of love with SOs when it comes to mutable stuff and mostly use plain c# classes with the serializereference attribute

[steady apex]

Is there any implementet function for finding (k) biggest elements ? k<< n

var closestGameObjects = gameObjects
            .OrderBy(go => (go.transform.position - origin).sqrMagnitude)
            .Take(5)
            .ToList();

that part of code have O(n) or O(nlogn ) ?

[hard estuary]

ScriptableObject asset should be treated as template. Depending on the game, you will want to either create an instance of a ScriptableObject, or create some sort of class that can wrap reference to the template and overridden stats. The second approach is more flexible, because you have an easy access to the template (which is useful if for some reason you want to restore the default state) and lets you easily swap templates without having to make a deep copy of it. But with enough effort, you will be able to achieve same goal with a single instance.

Wrapping it might be more performant in multiplayer games, because syncing whole object could take longer than syncing data about overridden fields. But it might be the opposite, if you're always overriding most of fields.

[night harness]

I'm still in my runtime SO usage arc so I haven't implemented anything like this before but is there a solid pattern to this kind of thing where your base is an Interface that both a base class and the scriptableobject inherit from that creates like a common and paired matching between them?

[hard estuary]

Sorting algorithms take nlog(n) operations.
When it comes to dynamically sorting elements, you can speed it up by preprocessing data into a self-balancing binary search tree. Modifying 1 element has O(log(n)) cost (where n is the number of elements in collection), but you would be able to retrieve k objects in time O(k), which works well for small k.
https://en.wikipedia.org/wiki/Self-balancing_binary_search_tree
But this solution wouldn't be efficient if you updated whole collection before accessing results (which is what will most likely happen, if you're comparing positions of objects that move every frame). Treat it as good solution for sorting,

If you're working with positions, then I would suggest trying a quad tree instead (or its 3D version). It's great for finding nearest elements.
https://en.wikipedia.org/wiki/Quadtree

[steady apex]

Move obiect (i detect object in range) i know that you can do it in O(n) if k is much smaller than n

I was not sure about that build in function (maybe it actually don"t make a sorting)

[lean sail]

how large is the list? id really just sort it and use the first X elements. the performance wont matter unless this list is like 1 million objects. In that case, you'd have that many objects in your scene and the game wouldnt run anyways

[hushed laurel]

Is there a reason to use a continuous extension of linear interpolation based on deltaTime instead of just calling it normally in a fixed update frame?

For anyone unaware, Lerp(a, b, f) called every second can be extrapolated into the equation
y=(a-b) (1-f)^x + b, where x is a float representing the number of seconds passed.

This would allow it to be called every Update() instead of every FixedUpdate(). Does anyone think this is useful?

[somber nacelle]

you already can call Lerp in Update provided you are actually using it correctly
https://unity.huh.how/lerp/overview

[lean sail]

a lot of what you're saying implies that you need to call Lerp in fixed update, you dont need to

[hushed laurel]

I know I can call it in Update, but then the amount of movement obviously depends on the framrate. My equation keeps the movement based on deltaTime.

[somber nacelle]

then the amount of movement obviously depends on the framrate
not if you use it correctly

[hushed laurel]

Alright then, how do you use it correctly?

[somber nacelle]

accumulate deltaTime in a variable, divide that by desired number of seconds the lerp should take and use that as the t value

[hushed laurel]

Oh, you're assuming that I want the lerped value to move the same amount every frame.

I don't.

[somber nacelle]

i am assuming you want to use lerp over a specific period of time which is what lerp is for

[hushed laurel]

I use Lerp to move something by a certain factor to a certain target every frame, so that it starts at a high velocity moving toward it and slows down as it nears the target.

[lean sail]

just saying, i dont think your equation makes sense either. it isnt the same as how you're supposed to use lerp, and suddenly you have 4 variables instead of 3

[somber nacelle]

starts at a high velocity moving toward it and slows down as it nears the target
this is not linear interpolation, this is just smoothing movement

also from that same page i linked before, here is how the link to how you can achieve what you want with lerp (even though you really shouldn't) https://unity.huh.how/lerp/wrong-lerp

[hushed laurel]

Why shouldn't I do that?

[lean sail]

also fixed update vs update shouldn't even be a choice here due to lerp. you use update if you want things to happen every frame. you use fixed update for physics stuff so it happens along side unitys physics loop

[somber nacelle]

because there are other methods for that

[hushed laurel]

What other methods?

[somber nacelle]

have you checked the docs?

[hushed laurel]

I've never considered that there could be other methods for what I want but Lerp, so no

[rough condor]

how to make a variable public and readonly but modifiable in inspector

[rigid island]

can't

readonly makes it not serializable
https://docs.unity3d.com/6000.0/Documentation/Manual/script-serialization-rules.html

[mossy snow]

public property with private getter + SerializeField attribute targeting the backing field. Doesn't make it read-only from the class but other scripts won't be able to modify it which is what I assume you want

alternatively, private serialized field + public getter which is less brittle but not as slick

[night harness]

its a shame unity doesn't have a nice working readonly attribute

[oblique spoke]

Don't crosspost.

my bad where should i post it then

Hello, does Unity provide any sort of info on whether the user is actively resizing the window? I would like to enforce the width and height to be an even number but not when the user is actively resizing the window.

I mostly need to know that the user is done with resizing

[cold parrot]

You need to make your own by polling screen resolution and potentially input state you want to use. Likely though a window being resized will mean the app may not receive input while doing so, or even update.

[fringe ridge]

If i have a BaseClass, and then ChildClass1 and ChildClass2, all are serializable. How can i have a list of BaseClass and create/edit instances of childClasses in editor?

really dont want to create a custom editor

[stone rock]

If it doesn’t update during that may actually already solve it then. I want to prevent the window adjusting when someone is resizing. I’ll go and test it and see what happens

[cold parrot]

#↕️┃editor-extensions

[fringe ridge]

so what you're saying is its not possible without a custom editor?

[quartz folio]

You need to use SerializeReference, it has no drawer for null by default

There are various packages out there that add a drop-down as a drawer

[lean sail]

I think it might still be able to if they stop actually dragging it, but I think youd just need to implement some delay like 0.1 seconds after the resolution last changed

[flint musk]

so how are hitboxes and hurtboxes supposed to work?

which one of them are supposed to be trigger, have rigidbody, or both?

i may be wrong, but neither of them is supposed to be a collider with the environment or characters , right? since they only serve to detect attacks and things of that nature

[elfin walrus]

yea

usually hurtboxes are the ones that scan for hitboxes and if they detect one, they deal damage to their owner

so hurtboxes are the things that take damage

and hitboxes deal damage

[flint musk]

right

[elfin walrus]

because usually there are more hitboxes than hurtboxes

[flint musk]

here´s my hitbox and my enemy´s hurtbox

the problem im having rn is that ontriggerenter is triggering multiple times

and the way that my hitbox works is that it gets enabled and disabled inside the attack animation

[elfin walrus]

usually the solution to that is having iframes, basically a fraction of a second of invincibility once something gets hit

[flint musk]

so what´s the point of OnTriggerEnter if it´s not gonna check only once?

[elfin walrus]

usually it only gets called once, not sure why it's getting called multiple times tbh

[flint musk]

i´ve seen around that if a trigger collides with another trigger it causes issues

and that at least one of the parties needs to be a collider or have a rigidbody

okay, i seem to have fixed the issue

it was the animation´s fault that seemed to be activating the hitbox multiple times

but thank you

[vestal arch]

wdym issues? they don't even interact

Hello does anyone Have good ressources for UI architecture ? I'm currently trying to do everything or most with UI toolkit

[mossy shard]

How can i call a functions after a few seconds in update (like looped) as in every 5 seconds an enemy spawns or smt

[shadow wagon]

the simplest way I'd do is have a float that I'd set to a value of 5, every update do timer -= Time.deltaTime. then when timer <= 0f, do whatever it is you want and then reset it back to 5

[night harness]

coroutine

[shadow wagon]

yeah, thats the other way

So, I'm trying to initiate a command for Yarnspinner where I enter a command named objectEnable, alongside the name of an object, into my Yarn file with the hopes of having the object be enabled when I do so and in the project itself, I'd have the objects disabled beforehand. The problem is, I keep getting a NullReferenceException: Object reference not set to an instance of an object error and I don't know why that is. Can anyone help me figure this out?

[ripe epoch]

Not sure if it counts as "good," but what I did for my project with UI elements is make my own "clickable" parent class that child classes can derive from. Whenever the player clicks, a manager on the player records all of the clickable scripts that were hit by the player, and calls functions like OnMouseDown, OnMouseUp, OnMouseEnter, OnMouseExit, OnHold, and updates a boolean that shows wether a player is hovering over something or not. I found that this approach let me make really robust systems easily, and I avoided a lot of the hassle that comes with UI toolkits by making my own barebones one. If you'd like, I can share the code.

[somber tapir]

I'm not sure if Yarnspinner can find inactive gameObjects. Try enabling the GO and see if you still get the error.

[fading epoch]

I still do!

[somber tapir]

which line is the error? Are you sure you have the dialogueRunner assigned in the inspector? Does the Debug fire in your method?

[fading epoch]

So, I get this big block of text
https://paste.ofcode.org/A3feE5nCugmzAJ4VebBGVC
It sounds like it's line 270, which is the objectName.SetActive(true);

[acoustic star]

This is essentially a copy paste I am making from the server whose tutorial I am watching so sorry for it being a little lengthy

Actually nvm

I'll explain it fresh

So I am watching a tutorial rn to make 3D chess

[vestal arch]

ok, start with the issue and immediate context

[acoustic star]

and it makes a 8x8 chessboard

[vestal arch]

we don't need the entire story

[acoustic star]

the problem is that when I hover it the tile changes layer

but the material doesn't change to the hover material

as you can see in the picture the layer is hover

[dire crown]

I've found a unity bug inside code, how do I report it efficiently?

[vestal arch]

the unity bug tracker

[acoustic star]

(usual layer is tile) but the material is still the same as all other tiles which aren't being hovered

[vestal arch]

(since you're here though, wanna run it past us in case it isn't?)

[gray cloud]

So presumably you have some code that changes the layer. Do you also have code that tries to switch material?
Are both of these pieces of code in the same location?

[vestal arch]

ok, where are you attempting to change the material?

[acoustic star]

So I am trying to change the material through the URP asset, with the changeObject feature

both of the materials are transparents

[gray cloud]

I've done hovering code dozens of times but never used that Renderer Feature I'm afraid

[acoustic star]

The raycasting code

[dire crown]

Sure, it's more of code missing a line. I'm making use of UnityEditor.Searcher package, and i was calling the method CustomSearchTreeUtility.CreateFromFlatList to ensure that, passed a set of elements like node/type/name they were properly sorted and organized.

However, I wanted to make use of the SearchItems property called Synonims, that basically allow you to add extra words that should return that item. But for some reason, they weren't working.

I checked the code of the package and found that on line 71 of that class there should be an additional
currentSearchNode.Synonyms = item.Synonyms;
to ensure that the synonims are transfered to the new SearchItems, otherwise they are lost

[tender willow]

RayCast on every single frame?

[dire crown]

they probably forgot to add that

[gray cloud]

Yep - that is completely fine if it's just like a "one time per frame" thing.
I know there's some controversy around it and bad practices, but that's how all hovering works afaik. And also, you won't see a single RayCast like that make a dent in the profiler.

What is a bad practice is to do that for a bunch of units, if you want something like an ant colony to use RayCasts to avoid bumping into walls, then that would be an issue.

But generally, things that are just for the player character you will have a lot more leeway for

One charater - fine. One frame - fine. Many characters every frame - double-check that.

[acoustic star]

Yeah this is just one player per frame

Board generation if you wanted to see that

[hybrid flower]

so i have this movement script that uses swipes on a mobile device to move, how would i translate this into a A & D keyboard movement

private void Update()
{

if (Controls.swiperight == true && Lane3 == false && Lane1 == true)
{
    Lane2 = true;
    Lane1 = false;
    Lane3 = false;
}
else if (Controls.swipeleft == true && Lane2 == true && Player.position.z <= 0.2f)
{
    Lane1 = true;
    Lane2 = false;
    Lane3 = false;
}
else if (Controls.swiperight == true && Lane2 == true && Player.position.z >= -0.2f)
{
    Lane3 = true;
    Lane1 = false;
    Lane2 = false;
}
else if (Controls.swipeleft == true && Lane1 == false && Lane3 == true)
{
    Lane2 = true;
    Lane1 = false;
    Lane3 = false;
}

}

[rigid island]

this is like an overconvoluted way of not using an array / index ?

if(input.getKeyDown(KeyCode.D)){ if(currentLane < maxLanes) currentLane ++;

lanes[currentLane]
etc.

Mr. Chexxor, you said you have done hovering a bunch of times, do you think you could help me implement a way to do it inside of my code 🙏

Or do you have any tutorial suggestions for doing it

[hybrid flower]

and this would be repeated 3 times ?

[rigid island]

why 3? you only need to check left bound and right bound

[hybrid flower]

so those 3 lines of could would be enough >?

i would need it for the A key aswell surely

[rigid island]

yes just A and D

all you're doing is ++ the index/int or --

[half venture]

Is this the right place to ask netcode and parenting questions?

[rigid island]

and declare currentLane and maxLanes

right

yes

as bools ?

[rigid island]

why bools?

you cant ++ / -- a bool

its an int

lane 1, 2, 3

[hybrid flower]

my Lanes are bools

[rigid island]

why are they bools

[gray cloud]

I'm about to grab some food but at least a couple pointers for now:

• In your Tile script, add a reference to the tile's Renderer (You will use this to switch materials manually)

• Add a material field for where to put the default material (so you can switch back when no longer hovering)

  • In Awake/Start or similar, set this ThisTilesMaterial = ThisTilesRenderer.SharedMaterial to save it for later (choose variable naming as you see fit)

• Add another material field for the HoverMaterial and assign this in the inspector for each of your tile prefabs if you have those

• Add a method on your tile class to enable/disable hovering

• In your current RayCast code where you switch layers, call this method as well

  • (You could move the layer switching code into this new hovering method)

• In the hovering method if setting to true then ThisTilesRenderer.SharedMaterial = HoverMaterial otherwise = ThisTilesMaterial

[mossy wedge]

Store the bools in an array and index them with an int, how about that?

[rigid island]

sure that could work but still no idea why they are bools in the first place

[mossy wedge]

Fair enough

[rigid island]

if you miss something bools can let you be in 2 different states/lanes at same time

[mossy wedge]

I'd prefer an enum for this tbh

[rigid island]

yes enums just numbers with labels

[mossy wedge]

They are one of my favourite language features, i just really like them

uhmm thats the problem idk where the mistake I made is basicly when I join with other player every single script is making errors xD

[rigid island]

well then you would start by sharing the errors

if you don't know how can a total stranger to the problem possibly know without any context

frankly if your first project is networking you will struggle more than need to

please don't use screenshots

so that GetComponent isn't finding a Rigidbody on this script

[tender willow]

yea but then why it is finding on the other zombie????

[vestal arch]

because that zombie has a rb?

[sonic portal]

yeah you use the RB variable but attached the Rigidbodfy to the Player Rb variable..

[vestal arch]

look at those 2 objects at runtime

[sonic portal]

you only need normaly only one Rigidbody for the object..

[vestal arch]

if you want to be sure, just add a [RequireComponent(typeof(Rigidbody))] to your parent script

[rigid island]

they are referencing the player probably to do stuff with it, that part is fine

[sonic portal]

you use 2 and attached it to the wrong ones

[vestal arch]

yeah looks like that's the case

and the "player rb" is not the rb of the zombie

[sonic portal]

in code he uses rb = GetComponent ...

[rigid island]

assuming they want to do maybe like a Hit react with AddForce to player or something

[sonic portal]

not PlayerRb thats the prob

[vestal arch]

but not playerRb = GetComponent

[rigid island]

Just assign rb through the inspector (no need for rb = GetComponent here)

[vestal arch]

that is not the prob

[tender willow]

gimme sec

[naive swallow]

They didn't mention any issues with playerRB

[sonic portal]

yeah cause it isnt even used

[rigid island]

how do you know?

we havent seen the entire script

[sonic portal]

in the code above he posted its not in

[rigid island]

I mean they showed us 2 functions not the entire script

[vestal arch]

@sonic portal how is any of that relevant
the problem is with rb, as evidenced by the error
and it's being assigned by GetComponent
that's all
playerRb is completely irrelevant

[tender willow]

https://paste.mod.gg/tpvvuwyikwsb/0

[sonic portal]

he just asigns the rb var

[tender willow]

whole codes

[rigid island]

its possibly playerRB is a hit react

[sonic portal]

thats what i said ..

[vestal arch]

yeah how is that relevant to the issue

[rigid island]

playerRb isnt even being accessed , so its irrelevant

[sonic portal]

he asigned the Rigidbody to the PlayerRb.. thats not used

[naive swallow]

...because it's not the issue? They showed the code for the one that is the issue

[vestal arch]

ok, that's not relevant though

[sonic portal]

need to asign it to the Rb

[vestal arch]

it's completely unrelated

[naive swallow]

They're different rigidbodies

[rigid island]

why would they assign the playerRB to the rb variable

[tender willow]

GUYS chill out here is the complete code

[naive swallow]

They're not related to the problem at all

[tender willow]

no need to speculate

[rigid island]

the solution is simple

put the rigidbody and assign it in the inspector..

[naive swallow]

Basically your issue was answered - this object has no rigidbody. P5YLO just keep insisting it was something else

And drowning out the solution

[rigid island]

rb = GetComponent<Rigidbody>(); is not needed anyway if you assign it through inspector which you should do for components on the same object

[mossy wedge]

The GetComponent does makes moving scripts around easier by not having to assign everything manually. I do prefer that

[rigid island]

I rather be assured everything is assigned then worrying if i ever move a component to a child everything breaks..

DI > runtime

also GetComponent can get unnecessary extra compute time..
Imagine you have thousands of gameobjects with GetComponents in Start /Awake.

You're gonna have a bad startup time

[naive swallow]

If you can drag it in, you should. It's faster that way, reduces scene load time

[vestal arch]

🤔 i tend to use RequireComponent+GetComponent for that
i guess "good DX" can be different for different people

[rigid island]

OnValidate I do use GetComponent some times
but thats editor only anyway and takes care of autoassign

[vestal arch]

but i haven't made scenes with a ton of objects, so maybe i'll encounter that load time issue later 😁

[naive swallow]

It's not a huge benefit, but when it's completely free, why not go for it?

[mossy wedge]

Ig I will continue on my getcomponent ways for now and really consider DI if I reach a scale where the performance impact is significant

[vestal arch]

dragging "this" object onto itself for multiple slots is worse DX for me

[mossy wedge]

It's just development time convenience in my case

[rigid island]

but usually its more handy with children objects

if you have like 10 fields for the same gameobject yeah its a pain lol

but yeah as you said Editor things like RequireComponent or GetComponent in things like OnValidate can mitigate that you get best of both worlds as long as it aint runtime

[vestal arch]

ah yeah i do use refs in that situation

[mossy wedge]

If you do then I have other questions to ask before that

[rigid island]

its not a huge deal esp if you dont have many objects but yeah its free optimizations so why not

[rigid island]

wdym?

oh nvm lol I get it

[mossy wedge]

I use a mix of refs and GetComponentInChildren in that case

[rigid island]

aside from OnValidate now I only use GetComponent if I need a runtime ref through collision or other queries

but TryGet ofc

we don't have built in TryGetInParent/Child but made extension method for it 🙄

[mossy wedge]

What would the use case of a get comp be in on validate? I'm curious

[rigid island]

as you said , if you dont want to manually assign all the fields to components and have them GetComponent before the game start

[mossy wedge]

Cool. I probably should settle with that then

[rigid island]

its the next best thing to SerializeField assignment imo

the problem only comes with the same issue at runtime, if you have multiple of the same component (two box colliders) but you want to only work with a specific one, you can't tell GetComponent which one you want as it grabs the first one

[tender willow]

if I have problem regarding multiplayer I should go to #archived-networking even tho the problem is somewhere within code?

[rigid island]

if its a networking question it goes there, so far you have not posted a networking question so it goes in #💻┃code-beginner

[somber nacelle]

SerializeField + RequireComponent + GetComponent in Reset is super nice. It sets itself up immediately when added to an object in the scene. And isn't running logic unnecessarily every time I make an edit like OnValidate would

[rigid island]

Ah Reset forgot about that lol

[mighty herald]

Can anyone help me, I'm trying to create a "Map" extension function which will map a value to another one as long as it's set.

// Given
int? i = null;
int j = 4;

AudioClip? c = null;
AudioClip d = /* a non-null audio clip */

i.Map(x => j);  // Should be an int? which equals to null
i.Map(x => d);  // Should be an AudioClip? which equals to null

c.Map(x => j);  // Should be an int? which equals to null
c.Map(x => d);  // Should be an AudioClip? which equals to null

I have this so far, but that won't work as it uses default, so when I map to a boolean it'll use false...

public static TResult? Map<TValue, TResult>(this TValue? value, Func<TValue, TResult> fn)
{
  return value == null ? default : fn(value);
}

[rigid island]

ohhh thought that was a Predicate<T>
nvm this goes beyond my monkee brain forget me.. lol

[mighty herald]

If I try to return null, it complains with this: Cannot convert expression type 'null' to return type 'TResult?'

[leaden ice]

Do you just want a Dictionary?

[mighty herald]

No, I'm just trying to map a value which may be null to another one, just when it isn't null

[leaden ice]

not sure i understand tbh

[mighty herald]

The code I'm using it for is this:

TaskResult? maybeResult = audioSource
  .Map(src => audioClip.Map(clip => PlayClip(src, clip)))
  .Map(x => TaskResult.Success);

The idea being I have an AudioClip? and an AudioSource? and I just want to play a sound if both are not null, then I want to get TaskResult.Success if that worked

Assuming PlayClip never fails of course (it always returns true for now)

[leaden ice]

wouldn't the code just be way clearer as:

if (audioSource.HasValue && audioClip.HasValue) {
  PlayClip(audioSource, audioClip);
  result = TaskResult.Success;
}```

[mighty herald]

Not in the way I'm used to code in 😅

[tender willow]

I guess I need to learn coding much better since I DONT UNDERSTAND THAT AT ALL

[fading quail]

using PrimeTween;
using Unity.Cinemachine;
using System;

public class CameraTransition : MonoBehaviour
{
    [Header("Cinemachine settings")]
    [SerializeField] private CinemachineCamera virtualCam;
    [SerializeField] private Transform followTarget;

    [Header("Initial values")]
    [SerializeField] private Vector3 startPosition = new Vector3(0, 0, -10);
    [SerializeField] private float startSize = 10.8f;
    [SerializeField] private float waitTime = 2f;

    [Header("End values")]
    [SerializeField] private float targetSize = 5f;
    [SerializeField] private float transitionDuration = 1f;


    private void Start()
    {
       
        transform.position = startPosition;
        virtualCam.Follow = null;
        virtualCam.Lens.OrthographicSize = startSize;
        Invoke("StartCameraFollow", waitTime);
    }

    public void StartCameraFollow()
    {
        // Tweenataan ortho-zoom
        Tween.Custom(virtualCam.Lens.OrthographicSize, targetSize, transitionDuration, onValueChange: value =>
        {
            virtualCam.Lens.OrthographicSize = value;
        });

        Vector3 destination = new Vector3(followTarget.position.x, followTarget.position.y, startPosition.z);
        Tween.Position(transform, destination, transitionDuration)
    .OnComplete(() =>
    {
        virtualCam.Follow = followTarget;
    });

    }

}```


Quite a long code but my cinemachine does a little down up when I set the followTarget. How can I avoid that?

[leaden ice]

That's like 6 lines of code, not long lol

as for the "updown" it's not clear just from the code what's causing it

[fading quail]

Well That is the only thing attached to the cinemachine

[leaden ice]

That might be the only piece of your code on the object but there are certainly at least 2 cinemachine components

What I mean is that your configuration of the camera along with the position and behavior of the objects in your scene is causing it most likely

[leaden ice]

what object are you having it follow

also it seems like your script is also manually moving the object

so it may be fighting with the CM stuff

[fading quail]

Its just this player. It doesn't have anything else than sprite now

[leaden ice]

is this 2d?

you should be using Framing Transposer not CInemachineFollow afaik

[fading quail]

Yeah 2d

Oh every Unity tutorial uses cinemachine 😄

[rigid island]

the new 3.0 changes are still a bit confusing 😅

[fading quail]

Framing Transposer is deprecated

I see that position composer is the new

[rigid island]

yeah they split some stuff up and confused me lol

worse case scenario i switch to 2.x

[proven thicket]

Ive been looking to create some voxel destruction similar to games like clone drone in the danger zone. Ive struggled to find any tutorials or templates for it

anyone have any recommendations?

[leaden ice]

mostly just seems to be a particle or VFX that spawns after the character dies

[proven thicket]

nah It usually removes cubes from the actual character thats hit

[leaden ice]

I think there's a combination of effects at play here

• a VFX for the little random cubes that break off
• Possibly replacing the character model with a set of individual MeshRenderers at the moment of death
• the particular renderers that god hit maybe using a "slice" style shader to simulate being sliced to pieces

Oh i see they also can have their legs broken off and stuff - probably just the characters are made of several pre-built pieces (individual MeshRenderers) rather than one SkinnedMeshRenderer

This doesn't scream to me full-fledged voxel engine destruction the way Teardown is for example

[hybrid flower]

So im making an endless runner that will spawn (for the time being) these 3 variations of Tiles that will continously spawn and move away from the camera,

here is my levelgeneration code: https://paste.mod.gg/wjsqnbmxuxzv/0

[vestal arch]

ok, what's the issue

[hybrid flower]

this is what happens when i run it.

[stone rock]

Is it required to use ComputeShader.FindKernel()?

If you have 2 kernels first CSMain for example and then below it CSSecond for example. Will the main one have index 1 and second index 2? Or is it a bit random?

[hybrid flower]

@vestal arch any clue why the tiles are spawning so weirdly

[leaden ice]

Problem 1 is you need to switch this to Pivot mode.

then look at your prefabs and make sure the root object pivot is correct

and that the prefab root is not offset weirdly

[hybrid flower]

root object being the player ?

[leaden ice]

no?

the root object is the "main" aka topmost object in the hierarchy of the prefab

talking about the tile prefabs

[vestal arch]

please don't ping specific people for help

[hybrid flower]

i mean you asked me about it and then didnt reply but all good

[hybrid flower]

root objects pivot is 0 0 0

[leaden ice]

and are all the children positioned reasonable?

Not hugely offset from the root or something?\

[hybrid flower]

negative

[leaden ice]

What's the issue exactly then> What are you expecting to happen that isn't happening

note that your code is repeatedly setting th eposition of StartPlane3

Also rather than going down the YandereDev path of "variables nam,ed with numbers after them" and "huge blocks of repeated code" I recommend to take a minute or so to learn to use arrays and lists in C#.

I'm guessing I'm doing it completely wrong

cause it just looks wrong

and there might be even more states let's say wall-running

it woudl probably add like 4 more if clauses

[rigid island]

not necessarily but do you need every state rn ? what do they do exactly when in that state?

[barren glade]

i mean yeah I kind of need these

cause i don;t want to slide mid air or crouch

[rigid island]

whats the point of JUMP if you have AIR

if you jump you're already in AIR no?

[barren glade]

cause when im in jump state

the jump() function executes

once

and switches to air

cause it would keep adding force

[rigid island]

but you can just check if you're AIR to prevent multiple jumps

[barren glade]

I guess

but the point still stands

[rigid island]

and your jump should probably use an Impulse rather than applying constant force

[barren glade]

if i need

a lot of states

like wall-running

or any others

if i want to extent

scale the system

it looks wrong idk

[rigid island]

you dont want to split into many states imo

some states can coexist

[barren glade]

okay but am i doing this wrong

[rigid island]

partially , I would clean it up a bit

starting with the suggestions i've made above

[elfin tree]

I'm trying to modify all my prefabs material, before a build, to be compatible with WebGL. My issue is that it modifies the actually prefab, not only it's instance in the build. How could I modify my code to only modify it within the build?

[shadow wagon]

you have to do cs instead of csharp with the backticks

[elfin tree]

the formatting is a bit off cause i ran out of characters

had to send as .txt

[shadow wagon]

mhmm

its interesting, ive seen a few people make the same mistake

[elfin tree]

csharp works btw

it does?!

[elfin tree]

example

[rigid island]

normally large code you send via links

[shadow wagon]

my bad then!

thinking back, i have only ever seen csharp when it comes to blocks of text sending as .txt

[rigid island]

both work fine

[elfin tree]

sure used to do that but we can .txt now?

ah kk

for my issue chatgpt suggests modifying the prefabs then reverting the changes after the build is complete, feels bad but would work most likely

and the prefabs would get corrupted if the build fails

ikr lol

[rigid island]

I still don't understand, what exactly needs to be modified here? and why

[elfin tree]

some of my materials are broken in WebGL

[rigid island]

oh like the shader?

[elfin tree]

yup

so i'm trying to replace some shaders during the build

if the build is webgl

[rigid island]

you have 2 different versions already yes ?

[elfin tree]

kinda

[lean sail]

Theres a reason the large code block paste exists

[rigid island]

Im oldschool..i would just make 2 copies instead of doing it by code

[elfin tree]

was doing this

    if (originalShader.name.Contains("poiyomi", System.StringComparison.OrdinalIgnoreCase)) {
                    var newMaterial = UnityUtility.CopyMaterial(renderer.sharedMaterial);
                    renderer.material = newMaterial;

                    newMaterial.shader = Shader.Find("Stamdard");
                    newMaterial.SetColor("_FirstOutlineColor", Color.black);
                    newMaterial.SetFloat("_FirstOutlineWidth", 0.025f);

[elfin tree]

and then how would you implement the fallback?

[shadow wagon]

discord puts massive walls of text into a .txt file

[elfin tree]

yeah it kinda sucks on mobile, on pc it shows the .txt

forgot about that

[rigid island]

fallback in what sense?

[shadow wagon]

what kind of message would you need to send thats 4000 characters long, to warrant nitro

[elfin tree]

if my build is webgl, how does it know to use the 2nd material?

[rigid island]

could just use seperate prefabs

you're in the editor so you already know you're doing webgl

[elfin tree]

then same question. how does it know which prefab to use?

i mean desktop builds can use any shaders, just not the webgl ones

[rigid island]

cause you're in the editor as WebGL build so you can make for example a WEBGL Boostrapper etc

[elfin tree]

it doesn't quite work like that, it will still work in play mode, but when you build it will break

(pink materials)

[rigid island]

I mean the object you need already has the shader with webgl compatible

all you need is a separate scene to initialize those instead of the "normal ones"

its probably more crude / less programmer friendly but it works, imo is most straight forward

they have all the same scripts anyway so the logic should still work the same

[elfin tree]

I feel like there has to be a way of doing this during the build instead

[rigid island]

sure there is, but more complicated

basically saying yes its a pain cause now you have copies of objects which can introduce annoyance at scale if you forget to change 1 but not the other.

[elfin tree]

well.. i guess i can just make a custom instantiate method that checks what material the prefab has (if in webgl) and modifies the material when needed

hopefully wont be too slow to do that in the browser

[rigid island]

do it during loading but if its a webgl not point to even put in the build the shaders/materials non-compatible

I would understand if you did automated CI/CD deploy but if you're in the editor mind as well do that before build

[elfin tree]

that's what i was doing IPreprocessBuildWithReport

but it modifies the prefabs

every item in the game pretty much needs that change so doing it by hand is not an option

[rigid island]

makes sense

mine had a few things so it was no biggie hmm

[twilit girder]

when i call
if (dataTotal.TryGetValue(kvp.Key, out uint currentValue1))
currentValue1 is always 0 instead of the actual value. Any ideas?

[leaden ice]

The key isn't present in the dictionary

[twilit girder]

Thanks! I was using currentValue1 instead of using kvp.Value in the else{}

[zinc flax]

I'm using cinemachine camera for 2D but whenever I increase the X and Y damping, when I move the player the camera follow but it's not smooth as if the camera act with low fps. I followed a tutorial on youtube and he doesn't experience this problem.

[leaden ice]

YOu'd have to share how you set everything up

as well as your cinemachine settings (including the brain update mode)

and how your player object is moving

[zinc flax]

Without camera damping, the player move is very smooth no problem here

This is the brain set on my camera

and this is on my cinemachine camera

[tardy tendon]

Can anyone spot what I'm missing here? No matter what I click, the ID is being set to 1.

[edgy ether]

this might be a bit of a strange question but is it possible to detect 3d colliders with a physics2d.linecast?

[elfin walrus]

why not a 3d linecast

[leaden ice]

lambda variable capture

[latent latch]

Two different physic APIs

[leaden ice]

you need to do cs int temp = i - 1; Button listButton = new Button() { portraitID = temp; }

[edgy ether]

well yeah that's the response i was expecting. but i was just curious if it was possible because i mostly didnt want to spend time rewriting all the 2d ray/line casts into 3d equivalent, so i was looking to see if there was any small workaround.

[elfin walrus]

doesn't look like you can tho

[edgy ether]

ah ok

well guess i'll just bite the bullet

[tardy tendon]

Thank you

[edgy ether]

was using 2d linecasts and raycasts to detect some collisions, but im in the middle of making some 3d sections and wanted a nice way to switch from 2d colliders and 2d rigid body to 3d without doing too much. but it's probably better i tackle this anyways for learning sake

[latent latch]

If you're going to use 3D, then just use the 3D API and forgo the 2D

lock axis if needed

[tardy tendon]

Just to check, did you mean to add the lamda to your example?

[leaden ice]

yeah

the point is

exactly what you have but with the temp variable

[tardy tendon]

I get it, but it's still not working. Using a temp variable now sets the ID to the array length...

[leaden ice]

show the new code

[leaden ice]

looks fine. What makes you say it's setting the ID to the array length?

[leaden ice]

what are we expecting to see here?
Also you have a lot of other errors 🤔

Where is that Debug.Log from?

[tardy tendon]

2 secs, gonna try something quick with some debug logs

I check what Portrait ID is set when the DrawActorWindow is called.

[leaden ice]

where is portaitID declared?

[tardy tendon]

The only other time I change this value is when I click on an actor to load up their details

This is the editor window

When you click an actor it resets the Portrait and Sprite IDs

[leaden ice]

this question is extremely important

[tardy tendon]

When the Window is created

[leaden ice]

well that's your problem

you have one portait id for the whole window

not one per button

er.. hmm I guess... this should actually work anyway?

Can you show that Debug.Log?

[tardy tendon]

Which one sorry?
