[lean sail]

Sure itd be ever so slightly more efficient, but it would be tedious as well. First it is unnecessary effort. Then you either need to store all the audio sources in a collection or use the Find function to get all of them. Either way, you are doing something I wouldnt consider cheap.

[long ridge]

Okay well is there a way to bake only certain parts or limit the range?

[rigid island]

probably yeah using volumes n whatot
check here too https://docs.unity3d.com/Packages/com.unity.ai.navigation@2.0/api/Unity.AI.Navigation.NavMeshSurface.html

[nimble cairn]

I thought this would have been most people's answers.

And you're right -- too much of a headache.

[mental rover]

you wouldn't be developing your game around hitting a framerate target without audio to begin with, even if it did help

[nimble cairn]

Of course not :p

[modern creek]

I'm having some issues with my content resizers. I have a method that attempts to iterate all the GOs in a transform and calculate the minimum size needed based on the max/min X/Y of everything contained. When I use a layout group, the layout group doesn't update their sizes until the end of the frame, so calculating the minimum size doesn't work until the next frame.

The advice I've seen indicates that I should use LayoutRebuilder.ForceRebuildLayoutImmediate(transform as RectTransform); but this isn't seeming to work in this one situation, and I've even double checked that the GO is activeInHierarchy.

I've tried a number of various "solutions" on the forums, including calling force rebuild twice, calling Canvas.ForceUpdateCanvases() before it, and enabling/disabling the GO in the lines immediately before this, none worked.

What else can I do, aside from using a coroutine to wait one frame to do this (which is going to lead to a one-frame flicker of these items.. not a huge deal but still annoying)

(code available upon request but it's a bit long)

[nimble cairn]

Is it possible to override the AudioSource volume limit of 1?

[rigid island]

prob not if the range is 0-1

[modern creek]

yes but it will have no effect. if you want something to be "louder than" 1 because you have some falloff or distance-to-the-listener things going on, you'll have to do that math yourself

[terse surge]

Why wont the spear script get the reference? (part show in vid, full script is spawner script)

Spawner script: https://gdl.space/ewoyoyijop.cpp
Warning script: https://gdl.space/emebefeluf.cs

[nimble cairn]

@rigid island @modern creek Could I use the AudioMixer component perhaps?

[rigid island]

if you're looking to make something louder why not boost the original audioclip ?

[modern creek]

I mean, you can use an audiomixer, sure? But I don't know what you're trying to achieve so I don't know if it's a good/bad idea. 🙂

If you have non-spatial sound then .. yes, what nava said. If you do have spatial sound then just place the audiosource closer to the audio listener

[rigid island]

indeed. if you need boost audio, Audacity has a neat Normalize feature to bring all clips to max loudness

[quaint rock]

think normalize only brings the peaks up to max

[nimble cairn]

I like the idea of giving the player the option to turn the sound effects up to 200%.

[quaint rock]

so how loud its perceived will depend on a lot of thigns

[long ridge]

Is there a way to get objects in a radius / is there a way to get navmesh sources by radius?

[nimble cairn]

100% just seems so, typical, lol.

[rigid island]

Oh maybe it was just Gain forgot which one hehe

[rigid island]

yes Overlapsphere

[long ridge]

uho

[rigid island]

but you need colliders

[quaint rock]

was just pointing out it does not limit or compress, so heavily compressed audio will sound louder then more dynamic audio even if both are normalized (sorry i am ultra picky about audio, was my past career)

[spring creek]

Gain on the mixer
Also #🔊┃audio

[modern creek]

This... doesn't look like it would compile? Why do you have internal as your access modifier on warning? You also don't (in general) check for == null in unity, since it doesn't work like you think it might (it checks if an item is null OR if it's been destroyed that frame)

[long ridge]

They do have colliders

[rigid island]

that makes sense

[modern creek]

What does this even mean, though? 100% is "full volume"

[nimble cairn]

Yeah

[spring creek]

Boosted above unity
It's not an abnormal concept in audio engineering
And VLC has it

[rigid island]

so overlap should get ur radius u want

[nimble cairn]

Don't think too deep into it I just want that number

[modern creek]

I guess I just don't really know what the OP is looking for aside from not liking 100% as the max volume. If you want it louder, the user needs to turn their physical volume up. If you want the audio clips themselves to be distorted, then you have to modify the clips in an external problem. If you want an awful audio experience just play two clips at the same time? shrug

[nimble cairn]

That's exactly the position I am in.

Is there an override for the default "100%"

[modern creek]

If you play two clips separated by a tiny amount you'll get the effect you might be looking for, but.. uh.. it's not really going to sound "good" i think?

[nimble cairn]

And I have found that in the Audio Mixer

[spring creek]

No

[modern creek]

yeah audiomixer is what you're looking for I guess.. although I still struggle to understand the use case aside from this ☝️

[nimble cairn]

It's just "nice" and I'm putting off more pressing work and this seems a reasonable distraction.

[terse surge]

I thought internal would work just as public, just that it doesnt show up in the inspector, since i wont use it in the inspector, i used internal.

the scrip can both compile and run, but yea spear i nthe Warning script is always null.

reason i checked for null is that.. well... i had an error with it not getting the reference, which i thought. Actually idk what i was thinking, i just had no clue how to solve this.

[vivid heart]

!code

[spring creek]

You can make your own value that goes from 0 to any number and sclae the 0 to 1 by that

And again, ask in #🔊┃audio

[modern creek]

If you want something to be private, make it private (and set it with a public facing method). If you want it to be private but want it in the inspector, use [SerializeField], that's what it's for.

You're also getting your warning component off of a prefab, it seems, instead of instantiating one? I'm not sure if that's what you're trying to do

Maybe it would be more helpful for you to describe what you're trying to do.. your code is a little.. broken? which is fine, but it's hard to understand what you're trying to do from the code alone

also @terse surge just fyi this is... never going to work:

    bool TrueFalseGenerator()
    {
        float randomFloat = Random.Range(1f, 3f);
        if (randomFloat == 1)
        {
            return true;
        } 
        else return false;
    }

You don't compare floats to integers, and also.. random.range with two parameters is going to generate a random float between 1.00000000 and 3.0000000000 (ie, maybe 2.583284834, 1.3472763472893, etc).. it's just never going to be even close to 1.0000000

if you really want a "true false generator" with this code:

private bool GetNextTrueFalse() => Random.value > 0.5f;

[terse surge]

my code is indeed broken.

What the spawner is supposed to do is spawn a warning symbol (gameobject looks like !! but with a gradient and all that fancy stuff) and a spear (well katana). the game object plays a sort of blinking animation, then sets the canMove in the spear script to true.

Basically what it would look like in game, is you get a warnign symbol o nthe side of ur screen, then a spear is launched towards the other side if the screen.

For this i have 2 prefabs, the warning prefab (again, looks like this: !!) and the spear prefab (which is a katana).

Spawner spawns them at the same time, passes some values on to em, and yea thats it.

When the warning sets canMove to true it destroys itself i nthe same method, and the spear destroys itself after 7 seconds.

this together should total a clean attack which the player has time to dodge.

currently, i have a problem with the referencing as you can see

and also... the spawn location in the else statement in the spawner script, but first id like to solve the reference thing

description of what im trying to achieve ^^

[modern creek]

k, that's helpful.. can there be more than one warning at a time? I suspect yes

[terse surge]

i did notice i got only the return from the if statement.... 3rd problem ig

[modern creek]

it's fine, you're here to learn 🙂 but it's important to understand the why

[terse surge]

when i got the reference error i believe it was only one error, i can try removing the if name != null and see if that helps

[modern creek]

a random float between 1.0 and 3.0 isn't "1 or 2", but rather it's a random float that could be 1.000000000 or 1.000000001 or 1.0000002 or 1.000000003 or 1.0000000004...... with a few million options up to 2.999999999999

[terse surge]

ohhh, yea i see it now, haha sloppy error on m yside, originally this method was used to generate a float in some other code of mine, but when i copied it over and changed the values i forgot it was for generating.. well a float

[modern creek]

I don't mean one warning in your compiler, I mean more than one warning monobehaviour

[terse surge]

i nthe script itself?

[modern creek]

in the game

SpawnAttack() - if this happens twice, does the user see two warnings on their screen?

ok, here, lemme try to sketch out some code and make this a bit easier for you.. you'll need to fill in the deets yourself:

[terse surge]

well after ti happens once, the game pauses as it usually does automatically when an error occurs so i never tested

also this should fix the 1 to 2 generator

[modern creek]

private void SpawnAttack()
{
  Vector2 warningLocation = ...; // calculate these like you did before
  Vector2 spearLocation = ...;
  Warning newWarning = Instantiate(warningPrefab, warningLocation); // you don't need the quat.identity parameter
  Spear newSpear = Instantiate(spearPrefab, spearLocation); // Just instantiate a "Spear", not a game object that you get the component of the spear from after.
  newWarning.Initialize(newSpear);
}

////// 

public class Warning : MonoBehaviour
{
  private Spear _spear;
  public void Initialize(Spear spear)
  {
    _spear = spear;
  }
}

[modern creek]

this "fixes it" but is still bad because it's like 10 lines where 1 would do and is also hard to mentally understand (it's hiding a cast from a float to an int, so it's not really clear). Just use my code above, it does the same thing and much simpler

[modern creek]

☝️

Also, just get into the habit of naming your methods with verbs - "TrueFalseGenerator()" is a thing, not a verb, so a reader would expect this to return a thing called "True False Generator"

[mighty flax]

btw I kept working on this - I got the terrain generating again and now can create a 32x32x32 chunk but the heightmap seems completely messed up - still getting the same leaks from the native arrays :/

[terse surge]

oh sorry, must have missed it. does it generate a new one every time the bool is used or..?

[modern creek]

yes, and really it could even be better as a property and not a method:

public bool NextBoolean => Random.value > 0.5f;

note the lack of () after the name.. so you'd just use it like this:

if (NextBoolean)
{
  // do something 50% of the time
}

[terse surge]

shouldnt andom.Range() be andom.Range(0, 1) ?

[modern creek]

changed to .value, sorry

[quaint rock]

why

[modern creek]

although I think range() with no parameters is 0,1, but as always, check the docs

[quaint rock]

range of 2 options and a Random.value > 0.5 are both 50 50 chance

[modern creek]

https://docs.unity3d.com/ScriptReference/Random.Range.html

So you're actually right with your above code - Random.Range(1, 3) == 1 will get you true 50% of the time.. but is.. kind of ugly for reasons that are hard to explain in a nutshell.. take my word for it now. 🙂

[quaint rock]

value is nice since you can do percentages of chance easily

[modern creek]

yes and if you really want to get fancy lemme sell you my optimal weighted list generator 😉

[quaint rock]

already got one, have it as a extension method on lists

[modern creek]

https://github.com/cdanek/KaimiraWeightedList

(I probably hawk this at least once a month lol)

(it's not really for sale, I was just teasing)

[terse surge]

ok so i think i get this, since i dont really need to access the gameobject itself there is no need to store it in a variable, rather id just store the script

[modern creek]

yes, and you can get the gameobject if you ever need it with newSpear.gameObject

(GetComponent() is slow and in general you don't want to use it)

[terse surge]

dam no gifs

[terse surge]

hmm i see

i kinda alr used it a bunch in my code 💀

[modern creek]

it's fine, it won't matter until later in your career.. but you may as well get in the habit of avoiding it

[terse surge]

but then... why did name != null not work? sure its slow but eventually it has to work, no? lols

[modern creek]

it's not really "slow" per se, but if you do something silly like have a GetComponent() in Update() for hundreds of game objects, your game is going to crawl and you're not gonna understand why

[terse surge]

i do indeed try to keep in mind all the tips i recieve here, but i plan on expanding my game jus ta wee bit so it might come back to bite me

[modern creek]

not really sure - but i only glanced at your code.. try to implement the code i gave you above and then see where you're at, maybe describe your problem again

[terse surge]

although originall the games intent was just so i learn how to make a game

[modern creek]

i do have to get back to work a bit so someone else might have to take your ball and run with it

[terse surge]

👍

[modern creek]

on one hand, don't use GetComponent() (or any of the find game object methods) because they're slow; on the other hand don't optimize your game prematurely (or probably ever) since YAGNI.. and if you do, you'll know

[long ridge]

Does it really matter if it only gets run once?

[modern creek]

no, that's fine

[long ridge]

I'm trying to figure out how to use NavMeshBuilder.BuildNavMeshData but I don't know what the position property should be

It says it's supposed to be the origin of my data but I don't know the origin

[rigid island]

why not just BuildNavMesh

[long ridge]

I get large lag spikes?

Is there a way to define an area?

Oh btw, I'm trying to update the navmesh when the user opens a door

[rigid island]

if ur doing this in the editor whynot use the Navmesh volumes

ohh this is runtime ?

[long ridge]

during runtime

[rigid island]

so use a volume and bake that if u want a particular area , no

[long ridge]

hmm I'll check

[terse surge]

anyone knows how to solve this error? how am i gonna give it transform if im still at the part were im instantiating it

[long ridge]

do volumes update dynamically?

[leaden ice]

You give it the Transform of the parent. If you're trying to give it a Position, you need to also provide rotation.

Look at the docs for the forms that take position/rotation https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

[rigid island]

Oh you mean like bake at runtime ?

[long ridge]

yes... I don't want to bake the entire map during runtime

Navmesh needs to update when a door gets opened/closed

[rigid island]

ohh maybe set navmesh surface on Volume mode instead?

I need to check again if it bakes for ALL

Ok it works

define your size here

this should only bake a certian area

[long ridge]

ooo

that helps a lot!

thanks

[rigid island]

proof 🙂

[long ridge]

[heady iris]

see also -- https://docs.unity3d.com/Packages/com.unity.ai.navigation@1.1/api/Unity.AI.Navigation.NavMeshSurface.UpdateNavMesh.html

[rigid island]

still mind boggling this function is async but not the BuildNav

[long ridge]

I tried implementing it but I get lagspikes with this and the navmesh isn't updating correct, I'm not sure if I missed something. Here's the code

 private NavMeshSurface surface;
    private NavMeshSurface GlobalSurface;
    void Start()
    {   
        GlobalSurface = GameObject.Find("NavMeshSurface").GetComponent<NavMeshSurface>();
        door = transform.parent.GetComponent<Door>();
        surface = door.GetComponent<NavMeshSurface>();



    }
    
    public void Animation()
    { 
        surface.BuildNavMesh();
        GlobalSurface.UpdateNavMesh(surface.navMeshData);
        door.IsPlaying = !door.IsPlaying;
    }
}

Is this correct?

Animation() gets called with an animation event

[rigid island]

basic stuff but did u make sure the function is running ?

put debug.log

[long ridge]

I know it is cause I get lagspikes when I open the door / close it, I've been using the script for a while

[rigid island]

the lag is normal from BuildNavMesh

its a synchronous function

why did unity did that, i have 0 idea

[long ridge]

I don't think I got lagspikes when I didn't include UpdateNavMesh

[rigid island]

use both in a coroutine should at least help with freezing

[knotty sun]

I have a mobile game that rebuilds the navmesh frequently, I have never noticed any lag in it

[rigid island]

same but also have another project where i needed Coroutine to mitigate the sync call

[heady iris]

I'm reasonably sure you just use UpdateNavMesh to make changes to an existing navmesh

also, I see you have a "surface" and a "global surface"

[long ridge]

I do..

[knotty sun]

I use Surface and Children btw

[heady iris]

I haven't done anything other than one large navmesh that gets updated, so I'm not familiar with how that'll behave

(since i haven't needed to do anything else yet)

[long ridge]

I might have misunderstood the concept, is the surface component only meant for baking the navmesh or does each surface hold it's own mesh?

[final sphinx]

How would I make it so the distance between the mouse and the player doesn't affect the projectile's speed? I've been trying to figure it out but can't. In the clip you can see that the bullet is a lot faster when your mouse is far away while you shoot and really slow when it's close
https://gyazo.com/9a5a15373234c6f4f58aed3925c7d2ee

private void shootBullet()
{
    if (onShootCooldown) return;
    onShootCooldown = true;
    Invoke(nameof(removeShootCooldown), shootCooldown);

    var currentPlayerPos = gameObject.transform.position;
    var newBullet = Instantiate(bulletPrefab, currentPlayerPos - Vector3.back, new Quaternion(0, 0, 0, 0), null);
    var bulletRigidBody = newBullet.GetComponent<Rigidbody2D>();

    var mousePosition = Input.mousePosition;
    mousePosition = mainCamera.ScreenToWorldPoint(mousePosition);

    var bulletDirection = mousePosition - currentPlayerPos;
    bulletDirection.Normalize();
    bulletRigidBody.AddForce(bulletDirection * 20, ForceMode2D.Impulse);
}

[long ridge]

I'm pretty sure UpdateNavMesh causes lag spikes since I don't get spikes when I comment it out

but I'll put it in a coroutine

[knotty sun]

lol bulletDirection.Normalize(); you are not actually normalizing

[rigid island]

its an async call it should be in coroutine anyway
eg

 IEnumerator Start()
    {
        var surfaceBaking = surface.UpdateNavMesh(data);

        yield return new WaitUntil (()=>surfaceBaking.isDone);
        Debug.Log("Done");
    }```

[final sphinx]

how else would i do it then?

bulletRigidBody.AddForce(bulletDirection.normalized * 20, ForceMode2D.Impulse);

causes the same problem

[hexed pecan]

How so?

[rigid island]

should work fine

[hexed pecan]

It modifies the struct in place

[knotty sun]

should not do, now you are normalizing which means distance is not a factor

[rigid island]

thats what they want though no?

longer distance = faster bullet

[hexed pecan]

Your mousePosition's Z value is probably at the camera

Make sure it's zero

[rigid island]

omg new Quaternion(0, 0, 0, 0), null); whyy

[knotty sun]

true, my bad

[rigid island]

you should not do this @final sphinx

use Quaternion.identity

[final sphinx]

i'm a beginneer and didnt know that existed

thanks though

[hexed pecan]

Yep, zero quaternion is not valid

[rigid island]

quaternion default is not 0,0,0,0

[final sphinx]

i tried doing that already but it didnt fix anything

[hexed pecan]

You sure? Can you show updated code?

[final sphinx]

ill redo what i did earlier gimme a sec

[hexed pecan]

Should set Z to zero after the ScreenToWorldPoint

Or you can just set bulletDirection's Z to zero before normalizing it

[final sphinx]

oh my god it's working now idk what i did differently from last time but who cares 🙏

thank you

nvm i normalized before setting z to 0 before

[forest ravine]

If a coroutine is awaiting another and externally that other gets stopped by StopCoroutine I believe the first never stops awaiting, can someone confirm?

[hexed pecan]

Good question, maybe test it?

Sounds unintuitive if so

[long ridge]

I still get lag spikes for some reason

 IEnumerator Bake()
    {
        var globalSurfaceBaking = GlobalSurface.UpdateNavMesh(surface.navMeshData);
        yield return new WaitUntil (()=>globalSurfaceBaking.isDone);
        Debug.Log("Baking Complete");
    }

    public void Animation()
    { 
        surface.BuildNavMesh();
        StartCoroutine(Bake());
    }

[forest ravine]

It's the conclusion I'm coming to seeing my "bug"

[long ridge]

and the navmesh doesn't update correctly...

it's not in the right place

or rather

the right place doesn't change

oh- hmm

actually

[rigid island]

surface.BuildNavMesh();
should also help if u put in coroutine

since its a synchronous call (it could freeze the code if takes long until done)

[lean sail]

Should be easy to test definitively with a new script. I do agree itd be unintuitive but at the same time, it sounds odd that you await a coroutine from a coroutine and pass that reference elsewhere so it can be stopped

[long ridge]

it seems to copy the current data, insert the new data and place it over the old which cause a lag spikes... like the nav mesh puts another surface ontop of the surface

[rigid island]

oh if you keep baking certainly

I think it does additive baking

how many navmesh surfaces did put ?

hopefully not 1 on each object..

[long ridge]

uh.. well, 1 surface on each door, 1 surface for the game

but I am only opening one door

[lean sail]

https://docs.unity3d.com/ScriptReference/AI.NavMesh.html
I didnt do too much with building navmesh at runtime but I believe you can just remove the old surface easily

[long ridge]

I know I can delete the data but the issue is that it tries to regenerate the map considering the lag

[lean sail]

I didnt see the original issue, but building a navmesh is not too cheap. Relatively speaking

Especially if it's a large surface

[long ridge]

Well that's why I want to bake smaller parts where needed

[lean sail]

What was the original issue? I dont really see why you would ever need a navmesh surface on a door

You could likely just throw a navmesh obstacle on it and call it a day.

[heady iris]

the nav mesh surface is used to define a region that gets a navmesh built for it

you don't put it on the door. you put it on a region of your level

just use a navmesh obstacle with Carve enabled and it'll work perfectly fine

Carve actually punches a hole in the navmesh.

[long ridge]

Isn't obstacle just for avoidance like something dangerous?

[heady iris]

no, it's for a thing that gets in your way

i.e. an obstacle

[hexed pecan]

Thats just one usecase for it

[heady iris]

you should read the documentation before you continue

[knotty sun]

gonna be damn difficult to walk through the door then

[heady iris]

Non-carving obstacles are avoided by agents, I suppose

they try to steer around the obstacle

[lean sail]

There is no sense of "dangerous" to your navmesh agents, although in real life itd be pretty dangerous to constantly walk straight into doors

[rigid island]

yes at most you have area cost but thats avoiding a certain area if lower costs are available

[hexed pecan]

Well using an obstacle for something like a temporary fire is ok

[heady iris]

https://docs.unity3d.com/ScriptReference/AI.NavMeshObstacle.html

I didn't know it could move around the navmesh

interesting

[hexed pecan]

Yeah Im thinking of experimenting with that to make bots avoid certain areas temporarily

And not getting in front of the main player when hes aiming his gun

Need to do some performance testing, though

[heady iris]

or to make them crowd in front of the player as much as possible

ruining their life

[hexed pecan]

Might get too expensive especially if I want different factions to avoid different areas, having to activate/deactivate and move them around all the time

[lean sail]

Interesting thought but also keep in mind if the gun moves onto the enemy, the enemy will instantly try to depentrate and it may look weird

[hexed pecan]

Yeah it needs to be different for enemies/friends

Not sure if it carves instantly or in the next frame or at the end of the frame

Gotta experiment

[lean sail]

I'm not entirely sure how the "areas" work but maybe you could define a danger zone

Like the walkable and jump default areas (or layers?)

[dense estuary]

I an experiencing a problem, it appears the gravity isn't the cause of the sliding up the slopes, it looks like that was already happening. When I remove the gravity from the movement code it just lowers in intensity. Here is my script: https://hastebin.com/share/wemekasewe.csharp. Here is a video of the issue: https://streamable.com/2m5w7u

[hexed pecan]

I think those are just for NavMeshModifier, which doesn't seem to update the navmesh in realtime unless you rebake it

But ideally yeah a zone with a high area cost would be better than just outright carving it out

[heady iris]

one possible issue is that you're using slopeHit.normal even when the raycast might've missed

I don't know what values get put in when that happens. Maybe just Vector3.zero

You should make sure you're actually hitting the slope here

[long ridge]

How do you exclude objects from the navmesh?

[heady iris]

Although, given that you're going downhill properly, you probably are!

[heady iris]

also, I can't really tell what the problem is by looking at that video

what is the unexpected behavior?

[dense estuary]

sliding up the slopes, that isnt my input.

[dense estuary]

Yeah, it doesnt miss the slope

[heady iris]

also, you still have gravity in your movement code

did you just set gravityMultiplier to zero?

ah, you don't use the gravity field, I see

I thought that was modifying velocity at first

One reason you could be going faster uphill would be if the controller was trying to move into the ground

it'd get pushed back out

I'd use Debug.DrawRay to visualize the velocity vectors.

but it still seems really weird for you to be forcibly moving uphill...

Does this go away if you set the acceleration to a huge value?

[dense estuary]

no

The acceleration also doesnt seem to be doing anything

[heady iris]

you're changing it in the inspector, right?

not in the script

[dense estuary]

Yes, I set it really high and the player still moves instantly.

[heady iris]

well, you do expect the player to accelerate really quickly when it's high :p

but I'd also expect this...

[hexed pecan]

I just implemented this and it's pretty dope

[heady iris]

planeVelocity = Vector3.MoveTowards(planeVelocity, desiredVelocity, acceleration * Time.deltaTime);

to completely kill your planeVelocity when you're not trying to move

so your velocity should be made up strictly of normalVelocity

and that shouldn't make you go up hill at all!

maybe unless normalVelocity is a huge vector pointing into the slope...

the character controller might depenetrate by moving up the slope

Debug or draw those vectors to see what's up

[dense estuary]

The yellow line is the velocity vector debugged: https://streamable.com/1liay8

[heady iris]

Oooh, yeah, I get it now

When you get onto the slope, some of your forward velocity is now perpendicular to the surface's normal vector

So now it's part of normalVelocity

And nothing ever reduces normalVelocity

[dense estuary]

Its going directly into the normal

[heady iris]

The CharacterController responds to that movement by sliding forward a bit

[dense estuary]

ah

that makes sense

so I need to set normalVelocity to zero?

[heady iris]

Try doing that first, yeah

You'd want to do that if you're grounded and the velocity points into the floor

[dense estuary]

How can I know if the velocity points into the floor?

[heady iris]

You could test if Vector3.Dot(normalVelocity, normalVector) is negative

I suppose that, if you're grounded, you should always kill the normal velocity

This will make you briefly lose speed when you hit a slope, though

you'll lose the part of your velocity that doesn't align with the floor

You could fix that by remembering the normal vector from last frame and rotating your velocity accordingly.

That'd be great for something like Tribes, where you slide around and conserve momentum

[rapid stump]

Hi! I need a bit of help lol
My goal with these functions is to spawn islands within the bounds of my mapPanel object, which is 10,000x10,000. Spaced apart, and far enough away from the objects edges to where the islands don't get cut off.
https://pastebin.com/zg0UsJnz
With my current variables (SpacingXOffset, SpacingYOffset, PaddingXOffset, etc) the maximum and min X and Y coordinates are
minXCoord: -4666.667
maxCoord: 4666.667
minYCoord: -4696.97
maxYCoord: 4696.97
Some islands STILL spawn outside of those bounds, although the position is calculated like this

float randomX = (Random.Range(-panelWidth / 2 + paddingX, panelWidth / 2 - paddingX));
float randomY = (Random.Range(-panelHeight / 2 + paddingY, panelHeight / 2 - paddingY));

I don't believe my collision detection function (IsPositionValid())would impact the positioning in this way, so I don't understand what the issue is.
Like right now, with this code I had 3 islands spawned at below X -4800 which is outside of the bounds I defined

[dense estuary]

The sliding is fixed now, thank you!

[heady iris]

nice (:

See if the velocity loss when you hit a slope is tolerable

[heady iris]

if not, this shouldn't be too hard

Quaternion.FromToRotation(oldNormal, newNormal)

basically

[dense estuary]

There isnt a velocity loss, I did this:

if (IsGrounded() && Vector3.Dot(normalVelocity, slopeHit.normal) < 0)
{
    normalVelocity = Vector3.zero;
}```

[rapid stump]

I think I found the problem

[dense estuary]

Although, I am experiencing a new problem when trying to apply gravity. Sometimes the gravity works, but other times it doesn't. I'm also not always sticking to platforms, instead I am flying off of them a bit. The code for the gravity is the same as in the script I sent, but in Update() I have velocity += gravity;. Here is a video: https://streamable.com/et4xl3

[heady iris]

You might need to "look ahead" a bit to get ready for a downward slope

Although, this looks more like gravity just isn't working at all (in some cases)

Maybe your grounding check is too eager, and you're killing your normal velocity when still a decent ways into the air

[dense estuary]

So I need to up the distance the groundcheck ray can shoot?

Yeah, um, increasing the distance of the groundcheck ray just makes the player float higher.

[heady iris]

Reduce, not increase!

too eager to say that you're grounded, I mean

One thing that might be useful to you is https://docs.unity3d.com/ScriptReference/Rigidbody.SweepTest.html

oh wait, this is a CharacterController. d'oh

I was going to say you could use this to test if you'd hit the ground by moving down a tiny bit

You could just use the controller's isGrounded, but if you completely remove your normal velocity, you might not actually hit the ground when you move

which would make isGrounded return false

I'd reduce the raycast's length and check if your velocity is pointing towards the surface you hit. Apply gravity before you do the grounding check

this way, IsGrounded() won't return true immediately after you jump

[hexed pecan]

CapsuleCast would be appropriate though, right?

SweepTest is useful if you have multiple colliders on the RB

[dense estuary]

Im using CharacterController

[hexed pecan]

I know

And it's capsule shaped

[heady iris]

Indeed; you'd just have to get the parameters right

it'll take a bit of fiddling

[hexed pecan]

True that. I make sure to always visualize this kind of things

Even made a gizmo function for drawing capsules

(Basically just three Gizmos.DrawMesh calls, 2 for the caps and one for the center)

Can be used to draw a spherecast too

[dense estuary]

I reduced the raycast length to 0.6 and started applying the gravity before the ground check, and now this is whats happening: https://streamable.com/qj0l9h

Btw, the randomly floating into the air while on the flat platform was me jumping.

[heady iris]

So you're popping a bit into the air when you come off a ramp

[dense estuary]

yeah

[heady iris]

it makes sense from a physics perspective (you suddenly went from a ramp to a flat plane, and you had a fair bit of upwards velocity!)

but it's not exactly what you want as a player

[heady iris]

This may help with that

You'd rotate the velocity vector to follow the ground

[dense estuary]

would I just get the oldNormal by logging the normal at the end of PlayerMove(), and the newNormal by logging the vector at the beginning?

[heady iris]

Yeah

This should only happen if you're actually on the ground, or your midair velocity will get messedu p

of course, deciding if you're on the ground will be a bit tricky...

This reminds me of the KinematicCharacterController package. It has a "force unground" method that explicitly sets your grounded status to false

it's important when jumping

If you were grounded on the last frame, and you haven't deliberately ungrounded (like by jumping), rotate your velocity to match the normal vector of the ground under your feet

[dense estuary]

Should I do this in its own function or no?

[heady iris]

It could be done separately, yeah

[dense estuary]

Something like this? ```cs
Vector3 RotateVel(Vector3 vel)
{

if (groundedLastFrame)
{
    var rotation = Quaternion.FromToRotation(oldNormal, newNormal);
    var rotatedVel = rotation * vel;
    return rotatedVel;
}
return vel;

}```

[heady iris]

Yeah.

That'll keep you from rocketing into the sky when a ramp ends

The other option would be to always remove your normal velocity as long as you're grounded

[dense estuary]

Yeah, always removing the normal velocity fixes it when going onto a downwards ramp, but not when leaving an upwards ramp.

Oh wait, RotateVel() is also doing nothing.

Here is my script rn: https://hastebin.com/share/otoyovanow.csharp

[heady iris]

Log to check when it's actually running.

[dense estuary]

What do you mean?

[heady iris]

stick a Debug.Log in the method to check when it's being executed

and also log the old and new normals

[dense estuary]

Here is what those log when changing between the platform and steep slope.

[dense estuary]

What do you mean? Isnt it executed every frame?

[heady iris]

only when groundedLastFrame is true

that could be messed up

er, I should say the actual rotation only happens if that variable is true!

the method is indeed called every frame; my bad

[dense estuary]

Okay, logging that, here is a video: https://streamable.com/hc75en

[dark kindle]

stack unity child game objec

[hexed pecan]

I personally have separate logic for sticking to the ground when walking over a ledge or entering a ramp

When the player becomes ungrounded, I use a physics cast to check if there's still ground a bit below me

If yes, snap to that hit position

[midnight skiff]

Hey y'all question about statemachines. In your opinions is component based or event based better to implement?

[quaint rock]

only things referenced in scenes in build get included in the build

so if a asset is not referenced by a scene but in a bundle it only ends up in the bundle

then make sure that scene is not in the build list

the scene ends up in the bundle then all assets that scene references end up in the bundle

you can end up with duplicated assets of some of those assets are also in scenes that are part of the build

[lean sail]

What would event based even consist of? A state machine usually directly calls the state's functions. You would need other code which listens to these events which is basically just a layer of abstraction.
I made my states inherit from mono for the ease of setting up in inspector

[quaint rock]

i would be making much smaller bundles

[upbeat hill]

Hey guys, quick question, how can I access the green axis shown here in code ?

[midnight skiff]

Component based the state machine stores every state like a game object and event based would process state changes through the state machine but store the states as classes like you said. I probably implemented the component style one indirectly idk lol I'll test them in a prototype project

[quaint rock]

its transform.up

that will get you a directinal vector pointing in that direction then you can add it to the world position of that object to put it in the same spot

[lean sail]

A component wouldnt be a gameobject, it is just a component, which is still a class. Im unsure how events would really help or be different here. It would just directly end up calling the enter, exit, update methods on the current state. It being a component has no affect on if you can do it, it just provides a much easier way to define what states are used

[midnight skiff]

Fair enough, thanks for the feedback!

[upbeat hill]

The behaviour I want is working with this :

arrowInstanceGOParam.transform.Translate(Vector3.up * arrowSpeed * Time.deltaTime, Space.Self);

Which is super weird I know

[leaden ice]

Why is that weird?

[quaint rock]

yes that works because its translate works in local space

so (0,1,0) is the direction of that green arrow

[upbeat hill]

ooooh

[quaint rock]

transform.Up gives that local direction in worldspace

[leaden ice]

Especially since you passed in Space.Self explicitly

(though that is the default)

[upbeat hill]

Yes but it is default

Still super confusing behaviour

[quaint rock]

like if instead of translate you just did
transform.position += Vector3.up * arrowSpeed * Time.deltaTime

it would be incorrect

since its world up, and transform.up was required

[upbeat hill]

Well not confusing, but I want to "store" this axis at a given frame

So the arrow in question will only follow the localspace green axis

why is that?

[quaint rock]

oh thought for a seceond you had it has a child of the character

its fine as long as its not a child of anything with rotation

[upbeat hill]

yes

It is as a child of another gameobject

This is my issue

I use the parent to place the arrow correctly

[quaint rock]

so make it not be a child of the game object when you fire it

un parent it, or instantiate a new arrow to fire and hide it

[upbeat hill]

can you get rid of all parents?

[quaint rock]

SetParent(null) will do t hat

[upbeat hill]

I'll investigate, thank you so much btw

Thank you for your patience

[quaint rock]

though the more common approach is to disable it and create a new arrow in its spot

and fire that

nah edit this, put links

read bot msg for links

[half vigil]

no errors

[rigid island]

does "links" not mean anything to you ?

[half vigil]

just not doing anything

[half vigil]

my b

thought u were talking to someone else

[rigid island]

ur the only one who posted question about code lol

last msg was 4 hours ago lol

[half vigil]

I be a bit acoustic fr

[rigid island]

yeah my acoustics act up too, too many concerts 😆

[half vigil]

https://paste.ofcode.org/mMWXyrR9uafeJFRhFwxz7L

[rigid island]

alr so what is supposed to happen and what is happening instead ?

[half vigil]

its supposed to grapple

but it doesnt do anything despite 0 errors

[rigid island]

well are you sure the code is even running?

[half vigil]

yeah

[rigid island]

how do you know?

[half vigil]

put in variables and stuff

[spring creek]

Often the reason something doesn't work has nothing to do with errors

have you written any Debug.Logs in the code?

[half vigil]

no

[rigid island]

wdym put in variables

[spring creek]

I would definitely start there. Write a debug log BEFORE the raycast, and after it

[half vigil]

filled them out in the inspector

[half vigil]

alr

[spring creek]

the one after should log the raycasthit

[half vigil]

will try

[rigid island]

that doesnt mean script is running lol

but yeah put some debug.logs and also would , screenshot and show inspector for what ur trying to Grapple on

[half vigil]

alr

inspector whie debug runs

[rigid island]

what

ur supposed to look at the logs in the console window

and show where you put the logs in code

[half vigil]

didnt you ask for inspector?

[rigid island]

Inpsector for the Object you want to grapple on

not the script

wht u tryina swing on?

screenshot its inspector

fully

[half vigil]

the only parameter needed is the layer

[spring creek]

Well, collider was important to see

[half vigil]

would debug.log(hit) show the name of the object the raycast hit?

[spring creek]

I think you would want hit.collider.name

[half vigil]

how it be feeling asking for advice on dsicord

[rigid island]

well wanted to make sure it had a collider and the layer yes

[half vigil]

alr thnx

alr so for some reason nothing shows uip in the console

when doing it on the swing points

[rigid island]

show where u put the debug.log in script

[rigid island]

so its not debugging when doing it on Cube(3) ?

[half vigil]

yeah

I renamed the ones in the grappleable layer to swingpoint but samething

nothing appearing in colsone

fuck

console

[rigid island]

is it logging for other colliders?

[spring creek]

You didn't do the debug BEFORE the raycast, just to verify it's actually doing it.
Also, do a Debug.DrawRay

https://docs.unity3d.com/ScriptReference/Debug.DrawRay.html

Just plug in everything from the raycast, and you will see exactly where the ray is going

[half vigil]

alr im just gonna scrrenshot your messages and do it tomorrow bc my mind is blacking out and I got class tmrw

thnx for thr help

[dense swan]

How do I modify object's RectTransform?

            RectTransform imageTransform = (RectTransform)image.transform;
            Rect imageRect = new() {
                width = tr.rect.width,
                height = tr.rect.width/image.sprite.rect.width*image.sprite.rect.height,
            };
            // below is compile error, said they are read only
            imageTransform.rect = imageRect;
            (image.transform as RectTransform).rect = imageRect;

[rigid island]

yes .rect is readonly

[dense swan]

how do I modify it's RectTransform.rect.width and RectTransform.rect.height?

[rigid island]

just use the sizeDelta

[dense swan]

sizeDelta is... using it's own anchor right and not parent's?
Do I also change the position using anchoredPosition?

[rigid island]

yes

[orchid abyss]

how to modify this so that i can use random.range?

[cosmic rain]

Like a random element from the array..?

[still depot]

does Unity not support prepaid subscription in-app-purchase?

[dusk apex]

What are you trying to randomize?

I could only possibly imagine you'd select a random string name before passing it to the function.

[cosmic rain]

Unity? Like subscribtion for the developers and purchases inside the editor??😅

[still depot]

ah nope, I mean for product store subscriptions in android and IOS

[cosmic rain]

Why would that depend on the engine?

It's all up to your app and the publishing platform.

And ads providers.

Google mobile ads for example has a plugin for unity. And even if the ads provider of your choice doesn't have explicit support, you could probably write a native plugin to support it yourself.

[orchid abyss]

i wanna be able to pass in 2 numbers as a range to play a random clip from the sfxsounds array in my audio manager

[cosmic rain]

Well, them do that.

Get a random number in range and use it as an index to get an element from the array.

[orchid abyss]

how to do that in this kind of array tho

[rigid island]

get the length as your max in Range

Random.Range can return you the int as a safe index

[orchid abyss]

how to return the index of an array element with its name

[still depot]

I use Unity engine and InAppPurchase package from Unity, but seems it's not support for prepaid subscription. I found some the same questions in unity forum and still got no clue

[rigid island]

wdym its name ?

[orchid abyss]

i wana do something like this

[rigid island]

pretty sure that error on Random is ambiguity between UnityEngine.Random and System.Random

range2 isn't a safe max index though, I would do int index = Random.Range(min, sfxsounds.Length)

should use the .length of array

what type is randomclip ?

[orchid abyss]

not gonna work cause its gonna select sounds you dont want

[rigid island]

wdym? so put only sounds you want in array?

or make another list , where are you getting that range2 int anyway

[orchid abyss]

its an audio manager it has all sounds

[rigid island]

so where is range2 come from as long as you're certain it wont ever be above your array size, you should be fine

btw cntrl + dot to fix the ambiguity for Random class

[cosmic rain]

Ok, so in this case unity is your provider of the ads. But prepaid subscription doesn't have anything to do with ads. It's a separate system. You can use unity in app purchasing package to implement the subscription purchasing and confirmation mechanism. Then you just use that data to decide wether a user should be shown ads or not.

[still depot]

actually I'm not asked about the ads. I just need to know Unity has support for prepaid subscription or not in their IAP package

[cosmic rain]

Well, did you check the iap package documentation yet?

I think prepaid subscription isn't any different from a regular purchase. What matters is how you treat it in the app.

[still depot]

yeah, Unity hasn't mentioned about it in their documentation or forum. so I'm confused about it because I have an error regarding it

[cosmic rain]

What error?

Also, there is a mention of subscription in the documentation

[still depot]

"product isn't found". I'm already have that subscription item in google play console, but the unity API give me that error

[still depot]

have you ever implemented IAP package from unity?

[cosmic rain]

I have a while ago.

[still depot]

especially for subscription product?

I have the same issue with this topic:
https://forum.unity.com/threads/are-prepaid-subscriptions-supported.1519978/#post-9570754

[cosmic rain]

What are you using code wise?

[orchid abyss]

🔥

[still depot]

yeah sure, we can also see similar problem in other threads. just type "prepaid subscriptions" in the search input, its flagged as a bug

[cosmic rain]

That doesn't answer my question.

[still depot]

what do you mean by "using code wise"?

[deep oyster]

Ok so, I've got a point, and I want to find the nearest location to that point that can fit a circle of size X

[cosmic rain]

I guess you're defining stuff in the inspector. That somewhat limits what you can do.
But here's a post about a similar issue and it seems to be resolved:
https://forum.unity.com/threads/unavailable-product-for-google-subscriptions.1298436/

[still depot]

please read it carefully

[mild coyote]

or maybe try going hardcore and call the billing 5.0 API in the google play sdk directly 😅
iirc, people used to use that way before unity's billing API exist

[still depot]

the solution on this thread is updated the plan to auto-renewing 😂

[still depot]

I'm not expert on writing a bridge plugin from Java to unity, so I avoid that 😄

[west lotus]

Iterate over a direction, using the radius as a fixed step size, fire a ray upwards with the length of the radius and if you dont hit anything you can fit.

[fervent furnace]

purple: known
blue:known

then you can form a right triangle with
width - r |\ r
|_
red line

[cosmic rain]

I see. They did mention that it's gonna be supported in v5.@still depot

Can't you handle it as a one time purchase though? It's basically the same.

[mild coyote]

this sounds like a hack but XD

• connect 1 to 2 with a spring joint
• disable 2's gravity
• simulate physics for a couple of seconds

[mild coyote]

me neither 😅
well, I think you'll need to wait until unity integrate billing 5.0 then, or there should be paid 3rd party iap plugin in asset store which updates their plugin faster

[deep oyster]

I didn't explain it well, what I meant was I have point 1 but I want to find the nearest point to it that fits a circle (which happens to be point 2)

[fervent furnace]

you just need to find the length of red line

[mild coyote]

connect 1 to 2 with a spring joint
this should be
connect 1 to a sphere or circle collider with a spring joint

[deep oyster]

I think I found something that works

[still depot]

yeah, I think we can use one time purchased and handle the duration manually by checking the buy date. but it looks like a cheating the way 😂

[still depot]

haha yeah, have you any recommendation for the 3rd party IAP? I will look forward for it

[cosmic rain]

What is it?

[deep oyster]

well, it's not actually what I was asking, just an alternative solution to the design problem I was trying to solve lol

[mild coyote]

I don't unfortunately
but the Simple IAP System seems to be still active, you can ask in the forum if it support prepaid subs

[deep oyster]

the player is a ball that can change sizes and I'm trying to see if they have room to grow to a bigger size. My solution is to cast up/down and take total distance, then repeat left/right

[cosmic rain]

Could also just do an overlap sphere at the predicted sphere center.

With the predicted scaled radius

[still depot]

alrighty, thanks

[split crest]

How do I get players to align on slopes as they run?

[orchid abyss]

how to make sure land sound effect only plays once i land on the ground

[lean sail]

Use the normal of the slope, which you probably already have from any grounded checks

[lean sail]

You could add a cooldown but I'd try to find out why its calling OnCollisionEnter so many times. At least it sounds like its playing some audio a lot. Do you have extra colliders?
Add debugs to see how many times it's even playing. Not really sure what that first code screenshot is for either tbh

[strange gate]

Hello guys, so I'm currently working on my new project. And I need some help with coding, so here is the thing. I need that when I throw a grenade and it explodes the monster turn In to a ragdoll, and not just keep running. But I tried many times and couldn't find any actual help. Any ideas how to fix that?

[deft timber]

how to fix what

are you trying to fix your existing code or implement it from scratch

[strange gate]

Thats the point, Im trying to figure it out whats wrong

I even wrote the Debug that whenever grenade explodes near the Monster ir will respond

But there it goes nothing

[deft timber]

then show the code

we are not wizards

how can we figure out what's wrong either

[orchid abyss]

[deft timber]

the code isn't from brackeys

[strange gate]

Grenade is, not code 😄

Code from chatgpt and the grenade is from brackeys

[deft timber]

then you are watching tutorial but you are ignroing the tutorial and doing codeo n your own

right

[strange gate]

no bro

[hard viper]

comments are good. those comments are useless

[deft timber]

yup never said comments arent good

[hard viper]

just clarifying

[deft timber]

int myInt = 0;

//increasing my int by 1
myInt++;

that is a terrible comment

for instance

[strange gate]

Grenade is from brackeys and the monster script is from chatgpt

Im just trying to combine these things in to a normal thing

[deft timber]

that code has nothing to do with explosion

you are detecting if the grenade touched the Rigibody

not if it exploded

you should do a Phsics.OverlapSphere for instance

[hard viper]

you can easily tell chatGPT code from human code because chatGPT regularly adds lots of useless comments.

[deft timber]

in Explode() method

[wide dock]

Combining anything with ChatGPT code will not produce a normal thing

[strange gate]

I see

[deft timber]

well even without the comments

4 foreach loops + non cached anything

anyway, that code has nothing to do with Explosion. It is triggered when grenade object entered the trigger

[hard viper]

but that could be incompetence. No human would go out of their way to type out a ton of comments which are useless

[deft timber]

yup

// Destroy the character GameObject
Destroy(gameObject);

so usefull

[strange gate]

Thanks for help

[fickle kettle]

so I've been needing some help getting down a loop point system for my game

I've got an audio manager alongside a class to play the music I want when the scene starts

here's the audiomanager

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

public class MusicSelecor : MonoBehaviour
{
    [SerializeField]
    private string TuneName;
    [SerializeField]
    private string IntroName;
    [SerializeField]
    private float IntroTime;

    private float MaxVolume = 0.4f;

    private bool IntroDone = false;

    private void Start()
    {

        AudioManager.instance.Play(IntroName);
        AudioManager.instance.SetVolume(IntroName, 0);
        StartCoroutine(AudioManager.instance.FadeAudio(IntroName, -1, MaxVolume));
        StartCoroutine(StartMainTheme());
    }

    private IEnumerator StartMainTheme()
    {
        yield return new WaitForSeconds(AudioManager.instance.GetTimeLeftInTrack(IntroName));
        AudioManager.instance.Play(TuneName);
        AudioManager.instance.SetVolume(TuneName, MaxVolume);
    }
}

the idea is we wait until the song intro clip has been played and then we play the lopped rest of the tune

[this is assuming that we can loop the song at the end of the audio file]

the issue is that my current method is inconsistent, and I am unsure as to why

using UnityEngine;
using UnityEngine.Audio;

[System.Serializable]

public class Sound
{

    public string name;

    public AudioClip clip;

    [Range(0f,1f)]
    public float volume;

    [Range(0.1f, 5f)]
    public float pitch;

    public bool loop;

    [HideInInspector]
    public AudioSource source;

}

this is the record base for every sound

[deft timber]

why not just make all the data as a scriptable object

[fickle kettle]

I intiially wrote the code as part of a tutorial

so this records the information for each sound and then the AudioManager generates the assosiated entries as audio clips

in any case that stuff works

but the audio intro to main tune does not

[static matrix]

what would be a good way to check if there is a position above or below that could be jumped to?

if(IsWalking){
            var EyeCheck = Physics2D.Raycast(transform.position + (transform.right*LookDirect)+(new Vector3(0,5)), -transform.up, Mathf.Infinity, 3);
            if(EyeCheck && !IsLeaping){
                if(Mathf.Abs(EyeCheck.point.y - transform.position.y) > 10){
                    LookDirect *=-1;
                }
                else{
                    
                    LeapPoint = EyeCheck.point;
                    IsLeaping = true;
                }
            }
            if(!IsLeaping){
                transform.position += (transform.right*LookDirect).normalized/40;
            }
            
            
        }

heres what I have now

does not seem to work

[cosmic rain]

What's 3 supposed to be? The layermask?

[static matrix]

yeah
has worked for me before but I can try an explicit one

[cosmic rain]

So you only one to hit the first 2 layers?

[static matrix]

?
no it hits the third layer (ground)

[cosmic rain]

No, it doesn't. 3 is 1 1 in binary.

So layer 0 and 1 are hit.

[static matrix]

it seems to have worked in the past but maybe i'm crazy

[cosmic rain]

Might want to double check it. Layermasks are bit masks, where each bit corresponds to a layer.

You probably had something on the default layer and it was hitting it.

Might want to debug what your rays hit.

[static matrix]

yeah that seemed to work
i think ill just use explicit layer from now on

[cosmic rain]

As for your initial question, maybe replace the magic numbers with an empty transform parented to the character.

[cosmic rain]

Wdym by "explicit layer"?

[static matrix]

like using a variable set to the layer mask instead of an int

[astral nexus]

can I somehow disable a scene with a SceneInstance type, but not unload it completely? I load scene with additive settings by addressables and all working good, but I can't figure it out how to just disable loaded scene for later use or something like this
I can enable, load, unload, but not just disable them after using

[cosmic rain]

Put all the scene objects under one parent and deactivate it🤷‍♂️

[heady iris]

Yeah, scenes don't have a "disabled" state

[hard viper]

a scene is just a mega prefab that tries to destroy everything that is not DontDestroyOnLoad when it loads in

and unity has a couple small tools to keep track of the current scene loaded, and loading them

[kind cipher]

Has anyone ever seen this issue? Trying to set some platform settings in a plugin, but it seems the settings don't realy stick. I click apply. Navigate to something else, come back, and the choices are gone.

[heady iris]

Anything showing up in the console?

[kind cipher]

nope. console empty

[static matrix]

everytime I use goto I feel like im channeling a dark art

[heady iris]

I'd look at the .meta file and see if anything changes when you hit apply

(and maybe changes back!)

I'd also peek at the "Asset Postprocessors" list to see what could be modifying the asset. I wonder if the ReactionMusic plugin is doing anything funny to it

and i'd also try duplicating a DLL (or creating a new one) and seeing if you can modify its import settings

[kind cipher]

thank you. I think that sent me on the right track. I ended up deleting the meta file, right clicking the plugin in the project folder and reimporting...and now it seems to be happy again.

[heady iris]

Funky

you can ask Git to diff the .meta file, assuming you're using that

[chilly surge]

Generally yeah goto is to be avoided, there are very specific situations it's good but most of the time you'd just be raising eyebrows.

[heady iris]

goto is great when you need it

[latent latch]

https://homepages.cwi.nl/~storm/teaching/reader/Dijkstra68.pdf

1968 trash talking goto

[knotty sun]

Dijkstra was an idiot

[heady iris]

djikstra considered harmful

[knotty sun]

Like so many academics with little or no practical experience, they only deal in theory and absolutes not in the real world and praticalities

love to see someone try to program in Cobol (which in '68 was probably the most used language) without using goto

[thin aurora]

If you need to use goto then it's time you refactor your code, because nobody needs that

[deft timber]

there ain't any

if you think about using goto then your code architecture is bad

no matter what edge case is it

[knotty sun]

sure you can better use goto, to break out of nested loops for example

[chilly surge]

It's literally used in C#'s source code.

[thick terrace]

goto was wildly dangerous at the time that was written, c# is a significantly safer language to do it in, if you are so inclined

[thin aurora]

The issue here is having nested loops

[deft timber]

so what

[chilly surge]

So I guess C# and Microsoft has bad code architecture then.

[deft timber]

how did you connect that

with what i said

in assembly for example of course you need to use goto

im talking about C# and Unity

[thick terrace]

the best use of goto is goto case in switch statements and i swear nobody knows you can even do that

[knotty sun]

never scanned a pixel image?

[deft timber]

the best use of goto in Unity is to never use them

period

[chilly surge]

Not assembly, literally the high level C# code of .NET's runtime and BCL.

[thin aurora]

Ever heard of having a positive flow in your code with no more than 3 nested braces? If you are an experienced programmer all your code would look like this

[deft timber]

and im talking about Unity

[heady iris]

this is ridiculous

[quaint rock]

in any modern langauge only thing i use labels for is labled breaks in loops

[heady iris]

Clean Code isn't a holy text

[thin aurora]

Lol

It's not hard to have consistency like that

Goto is a great way to ruin readability

[deft timber]

if you are using goto in Unity, i'd say you just aren't experienced enough or you lack knowledge about how to make proper code architecture

[latent latch]

goto when I can't be bothered to make methods for readability

[reef garnet]

Hi I'm working on a custom package for my essential starter tools, the sorts that I can use in every project, my problem is that one of these tools needs to be customized per project and that's not easy if it's sitting in the packages directory, is there a way I can have the package place a folder with these specific assets into the assets directory? Similar to installing an exported package maybe?

[chilly surge]

I don't have a single goto in any of my code, Unity or regular C# otherwise, and I can still see legitimate use cases of goto. I see people really think in absolutes.

[deft timber]

there is absolutely 0 usefull use cases for goto in Unity. If you are forced to do such thing then something went wrong

[heady iris]

actually, you're just not an Experienced Programmer

so you must be wrong!

[thin aurora]

There's 0 reason to use goto. Please share your examples and I will be sure to explain why it's a bad use case

[chilly surge]

Sorry, clearly my code architecture is wrong.

[deft timber]

show me 1 good use case of goto

in Unity

please

[quaint rock]

so why are you guys having a pointless nerd war over goto when literally 99% of you are on the same side of it

[heady iris]

goto is absolutely not something that I use frequently, but it can express some ideas in a way that's much easier to parse

I'm looking at code from Animancer right now

[spring creek]

They were joking, just to be clear

[heady iris]

it has a method that looks for an AnimancerState in a variety of different places

in each place that it succeeds, it uses goto to jump to the end, do a few things to the state, and return it

You could define a local function and then return the result of applying it, sure

[quaint rock]

sounds like where i would use a local function

[heady iris]

But I think it very clearly expresses the intent of the programmer.

[hexed pecan]

Breaking out of a nested loop without having additional bool checks

[deft timber]

i've shipped many titles with couple of game studios, never used and seen any goto from other programmers and probably will never see it

[heady iris]

"In this situation, go to here"

[latent latch]

I can see it useful for coroutines assuming you don't want to be making methods for them but otherwise eh

[quaint rock]

some langauges have that as a labeled break statement and only works in that context, go for exmaple can do a
break outerLoop where outer loop is a label above a loop

[deft timber]

if goto didn't exist in Unity, then I wouldn't even notice

[heady iris]

Great.

Glad to hear it.

Stop shitting on other people for thinking differently.

[hexed pecan]

And if you say nested loops are bad then you dont do game dev I suppose

[deft timber]

what are you like 10 😄

dont be mad

[fervent furnace]

java has this

L0:{
  your code, if fails then break L0;
}
```used this design in some of my java code

[hexed pecan]

Fen is a Ten

[deft timber]

i see

[heady iris]

This kind of "X considered harmful" argument makes you sounds like you've gotten all of your opinions from hot takes on Reddit

[reef garnet]

Hi I'm working on a custom package for my essential starter tools, the sorts that I can use in every project, my problem is that one of these tools needs to be customized per project and that's not easy if it's sitting in the packages directory, is there a way I can have the package place a folder with these specific assets into the assets directory?

[hexed pecan]

Hate this clean code propaganda

[heady iris]

i brought that tome up earlier (:

[thin aurora]

This is a help channel, I'm helping you trying to understand why goto is not good practice and you should not use it 🤷‍♂️

[deft timber]

they are just closed for wisdom

[thin aurora]

Also please share your examples of use cases because I still haven't seen one

[deft timber]

and passive-aggresive with cringe jokes

[knotty sun]

bool[][] grid

int x;
int y;
for (x=0;x<grid.GetLength(0);x++)
   for (y=0;y<grid.GetLength(1);y++)
      if (grid[x][y]) goto found
:found

[hexed pecan]

The label is right after the goto which is readable

[thin aurora]

If not, stop trying to defend it and maybe consider that it's in fact not a good idea rather than responding with "muh stop being so shitty"

[thin aurora]

Clear case of using a separate method to return the result

[heady iris]

https://github.com/asc-community/HonkPerf.NET/blob/eebb5af65101171fb625b13918500f3e04cdd926/Sources/HonkPerf.NET.RefLinq/Enumerators/Where.cs#L27

[MethodImpl(MethodImplOptions.AggressiveInlining)]
public bool MoveNext()
{
    tryAgain:
    if (!prev.MoveNext())
        return false;
    if (!map.Invoke(prev.Current))
        goto tryAgain;
    return true;
}

I consider this to be easier to read than a while (true) and a break

[fervent furnace]

making method is physical goto, make your eye and cursor goto line A to B

[knotty sun]

so you advocate introducing inefficiencies into the code to prove your point?

[latent latch]

This could pretty much be a method though which you can return from, but if you just wanted to do it all in update I can understand.

[thin aurora]

Ever heard of inlining?

[hard viper]

goto 🤮

[heady iris]

It is a niche feature that is not often needed or useful.

[thin aurora]

If you really care about those nanoseconds use that

[deft timber]

careful, some people love goto and you might get linched

[heady iris]

But banging this "goto considered harmful" drum isn't useful

[hard viper]

[heady iris]

You could do something like what TextMeshPro does.

[deft timber]

which one

[thin aurora]

But I don't really see how that is related to this. If I explain to you why I consider goto bad practice then game development is not really changing that

[heady iris]

It prompts you to import some assets into your Assets directory if it notices you don't have them installed already.

[deft timber]

it's like trying to convince anti-vaxxer that vaccines are actually good

pointless

Oh that's probably me, but consideirng I've been in this channel for four years there's no doubt people who block me because I argue very often

[deft timber]

wanted to have a friendly discusison about goto but some people got mad af

[heady iris]

Note that if these are scripts, then that's not going to work very well : if they aren't present, your code isn't gonna' compile

[deft timber]

turned out it was me 😄

[thin aurora]

No it is me, the post below was blocked 😎

[deft timber]

jelaous

[hard viper]

i hear righteous indignation being typed out

furious clickety clacks of keyboard keys

[reef garnet]

they are in fact scripts

[chilly surge]

334 instances of goto just in dotnet/runtime alone.
The most common use case if for final error handling/final returning logic, anything in the form of:

ReturnType DoStuff(Lots of, Arguments here)
{
    if (someCondition)
        goto Throw;

    DoSomeIntermediateLogic();

    if (someOtherCondition)
        goto Throw;

    DoSomeFinalLogic();
    return TheReturnValue;

    Throw:
        DoSomeCommon;
        ThrowingLogicHere;
}

Yes you can absolutely just rewrite it to remove all goto by abstracting away like:

bool TryDoStuff(Lots of, Arguments here, out ReturnType result)
{
    if (someCondition)
    {
        result = default;
        return false;
    }

    DoSomeIntermediateLogic();

    if (someOtherCondition)
    {
        result = default;
        return false;
    }

    DoSomeFinalLogic();
    result = TheReturnValue
    return true;
}

ReturnType DoStuff(Lots of, Arguments here)
{
    if (TryDoStuff(of, here, out var result)
        return result;

    DoSomeCommon;
    ThrowingLogicHere;
}

Yeah look, you got rid of goto cool, but now you have two versions of the same method, repeating the name and arguments and return value twice. Now you may argue "okay maybe just don't throw and always use try pattern" but that's not the point, this is evidently a use case enough that it has over 300 matches in dotnet/runtime alone.
Like I said I don't ever write goto myself, but failing to see the utility of goto and claiming it's always bad is quite the black and white world view you have.

[hard viper]

sometimes I regret being right

[reef garnet]

basically an Input solution that I've extended from a tutorial that depends on the InputSystem

[heady iris]

What stuff do you need to customize?

[knotty sun]

well said

[reef garnet]

If I need to add more inputs

[heady iris]

also, please continue this discussion in a thread if it must continue.

It is monopolizing the chat

(referring to the goto discussion, not you, Babbitt)

[reef garnet]

I'm well aware

[hard viper]

I see goto as inviting the vampire into your house. He can’t hurt you unless you invite him in. Even if he does know a thing or two about wine.

[thick terrace]

one way to do this, if this is the user experience you want, is to have some config asset which has a type field you can set a type in, then your actual code can get that type at runtime and instantiate it (and call some virtual methods or whatever, assuming you have a base type)

[reef garnet]

https://github.com/5Babbitt/Babbitts-Custom-Tools/tree/main/Runtime/Input here are the scripts in question that I'd like in the assets folder

[heady iris]

you might invoke the "open-closed" principle here

your code should be open for extension and closed for modification

So you shouldn't need to edit the existing scripts.

the user should be creating new code that interacts with your existing classes

[quaint rock]

yeah i would never expect someone to edit a library for regular use

[heady iris]

I only edit a library when there's something actually wrong

[hard viper]

yeah, this is a massive violation of the open closed principle

[quaint rock]

they can extend it, implement its interfaces or pass functions into it

[heady iris]

well, or when I really really really want a callback in a specific spot

It shouldn't be the standard way to add stuff to your input system!

[hard viper]

your point is made, but does not make me fear it any less

[heady iris]

You might look to the new input system for inspiration.

You can add new processors, input controls, etc.

[reef garnet]

I am using it

[heady iris]

As in, look at its code!

[hard viper]

we mean to look at how it works

[heady iris]

It's very open to extension.

[quaint rock]

could the user code not extend or implement interfaces you expose, then your system has a init step where there user can pass those implementations back in for it to use

[chilly surge]

I'm not encouraging anyone to write goto, I don't write any myself. My argument is merely that there is utility in goto which some people seem to fail to grasp.

[hard viper]

i am aware of the utility. It has a lot of utility. I fear its usage.

[heady iris]

This adds a new input processor, for example

[quaint rock]

we dropped the topic on the main thread

[heady iris]

(this is taken from Cinemachine)

[chilly surge]

My bad, I shall stop.

[reef garnet]

This is the main script, it gets a reference to the generated input class and uses interfaces to receive input callbacks from the action maps, when implemented the interface generates a method for each input and then I add logic to send whatever data I want out as an event

[hard viper]

current topic is open closed principle

i’m not sure I understand how this works in a way that provides value tbh

[reef garnet]

so if we're talking the open closed principle I'd essentially be making a class that inherits all the default logic that I can then add more methods to execute?

[hard viper]

you made a middleman, such that I need to go:
input system => my own class => your class => my class that wants to know about specific input events

because i need to feed your class inputs somehow to get it to trigger and interpret events

that’s right, right?

[thin aurora]

What's very interesting in these cases is that 99% of these aim at saving a few keypresses by merging a few statements into one, and I would really not consider those a good use case because you're going to end up spending more time reading the logic. Also, a lot of these methods use a goto as they return a value afterwards, like this one. However, I feel like splitting this method into a separate one is way better, as instead potentialHeader is returned and this would improve readability and also get rid of the goto spam the code currently has.

[heady iris]

Please make a thread.

[hard viper]

to whom do you speak

[reef garnet]

around there yeah, I uses scriptable objects as a sort of tangibly accessible event and pass the data to that, then on any objects that I need it I use an event listener class to pass that to the script that wants it, it's a little bloated but is still quite clean

[thin aurora]

Also, you could make a nested method instead in a lot of cases. I would advice against it still it still has the issue of requiring to jump around the code like goto does

[heady iris]

This topic has monopolized the chat. Please make a thread.

[hard viper]

idk i feel like this is a lot of hoops to jump through, when I could have just written my intermediate input parsing class, and left it at that

[thick terrace]

best to use the reply feature after an argument because various people have each other blocked and are confused now i think lol

[deft timber]

i mean in terms of making a middleman for input system, which I think does have value. But this package requires the user to also make a middleman. Which makes it less useful.

[reef garnet]

To clarify it's basically InputSystem => Input Reader => my class

[hard viper]

how does input reader know which inputs from inputsystem to listen to

[reef garnet]

Using the interfaces generated by the input class InputReader : ScriptableObject, GameInput.IGameplayActions, GameInput.IUIActions

**IGameplayActions **and **IUIActions **will implement an empty method for each input withing those respective action maps

[hard viper]

where is GameInput? is it one of your classes with a source generator?

[reef garnet]

then I add a variable for the event, and send the callbackcontext data using that event in the new methods

[reef garnet]

it's generated by the inputSystem

[hard viper]

i see. This is all kind of abstract at the moment, so you’d need to kind of show the “how you’d do it normally” vs “how you’d do it with this package” comparison

[reef garnet]

In regards to the package I actually copy the scripts into a folder in the Assets directory then delete the package ones to avoid conflict but that feels dirty

If I add a new input I create the binding in the inputactions asset, the go to my InputReader class and add simple logic on what I want from the input (Vector2, bool, trigger, etc...) then make an event object, connect that to the InputReader and raise the event using the data from the input

[hard viper]

I mean you should show what the package does in the specific use case

[reef garnet]

Just so that I can use it in multiple projects and it automatically updates as I import it from github

I'm new to creating packages so I don't know all the ins and outs yet

the inputreader is just helpful in that it controls which is the current action map, and receives all input callbacks in one place

back to my original question, is there a way to install a package from github and add some of the files to the assets directory instead of the packages directory

[knotty sun]

you can add all of it to assets, not sure how to go about some though

[reef garnet]

how would adding all to assets work

[knotty sun]

just move from the package cache to assets

[reef garnet]

what just drag and drop?

[knotty sun]

no, outside of unity

[reef garnet]

How could I achieve this?

[knotty sun]

do you know where the package cache is in your project?

[reef garnet]

not sure about the cache haven't played around with those

[knotty sun]

look in Library->PackageCache, there you will see all of the source for all of your installed packages

[reef garnet]

Ok I found it

[knotty sun]

ok, so move the folder for the package you want into the Assets folder and remove it from Packages->manifest.json

[reef garnet]

ah ok

that is an option, I was looking for a way to automate the process, though I suppose I could do that with FileUtils

[knotty sun]

simple .bat file will do

[reef garnet]

basically want this to happen when I import the asset or like an edit menuy action

[knotty sun]

doable but you would need to write an AssetPostProcessor

[reef garnet]

I wouldn't mind looking into it

thanks for that

I am currently building an AR application and I have the problem that my assembly prefab does not appear 0.2 meters to the right of my marker as specified in the code. The assembly prefab appears on the marker... Does anyone know what I can do to make the assembly appear 0.2 meters to the right of the marker? The "Place Prefab Near Marker" Script is giving the positioning of the Assembly prefab. The Code of the "Place Prefab Near Marker" Script is as follows: using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR.ARFoundation;
using UnityEngine.XR.ARSubsystems;

public class PlacePrefabNearMarker : MonoBehaviour
{
public ARTrackedImageManager trackedImageManager;
public GameObject prefabToPlace;
private const float offsetDistance = 0.2f;

private void OnEnable()
{
    if (trackedImageManager != null)
        trackedImageManager.trackedImagesChanged += OnImageChanged;
}

private void OnDisable()
{
    if (trackedImageManager != null)
        trackedImageManager.trackedImagesChanged -= OnImageChanged;
}

private void OnImageChanged(ARTrackedImagesChangedEventArgs eventArgs)
{
    foreach (var trackedImage in eventArgs.added)
    {
        if (trackedImage.referenceImage.name == "MarkerIcons01")
        {
            Vector3 positionOffset = Vector3.right * offsetDistance; // Offset um 0,2 Meter rechts vom Marker
            Quaternion rotation = Quaternion.identity;
            Instantiate(prefabToPlace, trackedImage.transform.position + positionOffset, rotation, trackedImage.transform);
        }
    }
}

}

I'm having some issues on how to best determine collisions when using a tilemap in regards to moving vertically (think jumping on platforms) when hitting the sides/underneath of them? I can't seem to wrap my head around on how to tell when I hit the sides of the tiles vs the underside/bottom of them. Any suggestions would be so helpful!

Sorry for the longer code, I edited to include the paste site instead - thanks for the info!

[rigid island]

what are you trying to do with tiles i dont understand

You want to detect the sides and bottom, are you trying to use Platform effector on tilemap or something?

[sudden bobcat]

In simplest terms yes I am trying to detect hitting side/bottoms of tiles.

I have two tilemaps, one for background and one for collisions. The one for collisions has a tilemap collider 2d and composite collider 2d. My character has a rigidbody to interact with the tilemap that has the colliders. When I press space, I move my player upwards. If my player is moving upwards and collides with a tile the only checking done is against the players y position. This causes issues when the player is moving upwards and collides with the left or right side of a tile. My code sometimes determines that collision on the side is like hitting the underneath of the tile, because it's based on the players y position.

[rigid island]

I would play around with Raycasts and overlaps

for example you can put a ray going up

overlap for checking the overall shape

[steady marsh]

I'm trying to animate the width of a VisualElement. I thought to just create a .hidden and .visible class, with 0% and 20% width respectively, and this works when I swap around using a Button, however I can't get it to animate on creation (I assume because the class swap happens before the first draw?)
Is there a neat way to get this to work?

I hope this ok. For some reason it doesnt work as I want it to work...

[leaden ice]

HOw about a screenshot of the spawned assembly object being in the wrong place...?

Also you should set your tool handle position to "Pivot" not "Center". It's the thing on the left here:

[leaden ice]

What on earth am I looking at here lol

[white coyote]

You asked me to send you a screenshot of the generated assembly object in the wrong place, didn't you? This is the screenshot; I made the other parts invisible. Only the plane and the start button are visible.

[thick terrace]

your position offset is in world space, it seems like you'd probably want it relative to the marker position or something like that?

[white coyote]

yes, exactly

[leaden ice]

this is not a screenshot this is a photograph of your laptop?

also I wanted to see you know... the editor ui

with the inspector

etc

[thick terrace]

it's AR haha, this is a screenshot

[leaden ice]

showing the position

[leaden ice]

I see, that explains my confusion

[thick terrace]

it is confusing to look at

[leaden ice]

Anyway it's probably offset just fine

easier to see by looking in the scene view

[thick terrace]

https://docs.unity3d.com/ScriptReference/Transform.TransformVector.html is this what you need?

[white coyote]

I have tried it but it doesnt resolve the problem..

[white coyote]

I have tried this one too but it but it doesnt resolve the problem..

[leaden ice]

You tried what? I didn't say anything to try here

[white coyote]

change the settings from center to pivot

[leaden ice]

that isn't going to fix anything, it's going to let you see what's actually going on in the scene window

You will be able to see the actual positions of your objects when they are selected

[white coyote]

Ahh, I see. Do you have any suggestions how to resolve the problem ?

[zinc forge]

is this a good place for ML agents help?

[leaden ice]

What problem? You still haven't shown a screenshot of the spawned object being in the wrong place.

1. Play the game
2. select the spawned object
3. take a screenshot with the spawned object selected

i can not get the deselect to work (if !parent transform)

[leaden ice]

Well OnPointerClick is only going to run if you click on this object

so it doesn't really make sense to detect you clicking outside of this object there...

[tender arch]

oh

so how do i fix that
