it is for sure able to reference to that value I just dont know how to SetActive and GameObject.Find

#

or component find idk

spring creek
#

So a third object. Is the object in the scene before hitting play? Make a public field and drag and drop it. If not, I'll need more info. But once you HAVE the references:

if (thirdObject.valueICareAbout >= valueNeeded)
{
  childObject.SetActive(true);
}

Dumb problem/question... I attempted to migrate my project from 2022.3.9 to 2022.3.10 but there was some package dependency error so I had to revert back to 2022.3.9. Works fine, but in the package manager I'm now seeing all packages labeled as "Custom", and I'm not able to update any of them. Any idea how/why that happened, and how to fix?

I don't know though, just to be clear haha

jaunty sundial
#

im actually changing the prefab file

spring creek
#

I assume you mean changing it in code, right?

jaunty sundial
spring creek
#

Then yeah, that is expected behaviour

jaunty sundial
#

how would i stop it doing that then

spring creek
jaunty sundial
#

change it back when on start?

spring creek
#

Why are you modifying the prefab btw?

jaunty sundial
#

so it changes of all of the instatiated objects

spring creek
#

Hmm, ok. Well I guess that's one way to do it 😄

jaunty sundial
#

is there a better way

spring creek
#

Save the objects and change all the instances only. Or have them reference an object with the layer and subscribe to when it changes via an event invoked by the setter

jaunty sundial
#

how do u change all instaces

spring creek
# jaunty sundial how do u change all instaces

You save all of them when instantiating and iterate over the list you saved them in

Or

When instantiating, have them subscribe to an event evoked via a layer property setter, and when you change that property they will all set themselves

#

I would do the latter

jaunty sundial
#

Instantiate(genTube, cylinder.transform.position, cylinder.transform.rotation);

#

thats my code for instantiating them

spring creek
#

You can do:
GameObject go = Instantiate(...);
then you use receive a reference to the instance right there

#

then you just have that instance subscribe. Maybe to an event on the object instantiating it, maybe to a singleton

jaunty sundial
spring creek
#

Instantiate has a parent parameter if you want to set them as children though

jaunty sundial
#

that didnt work

spring creek
#

I should also say, if you instantiate a component from the prefab you can get the reference to that component. So, like:

MyScript clone;
clone = Instantiate(prefabScript, ...);

then you don't have to do a getcomponent or anything
This is generally preferred, because you rarely need directly reference gameobjects (all monobehaviours can just call .gameObject to get it when needed)

Im trying to add default methods to some unity events using the reset method, and it works fine for events that dont have any arguments, but I can't seem to figure out how to give them an argument using the AddVoidPersistentListener method from UnityEditor.Events

private void Reset()
    {
        UnityEventTools.AddVoidPersistentListener(unHoverEvent, ClearHoverPrompt);
        UnityEventTools.AddVoidPersistentListener(hoverEvent, SetHoverPrompt); //this method takes a string argument and gives me an error since there is none
    }

#

Do you mean a UnityAction? Im not sure how (or why) you would give an event a parameter

dawn belfry
#

Wondering if anyone could help me out with this. I have a Behavior tree and im trying to get the players location since I cant make a gameobject public and drag it in, in the inspector. Any way I can find the players location through regular code. I have tried getting the tag of the player on start within my attack node. But its just not working out. Im also using physics.checksphere for the transforms location from my ai.

#

what if the event is subscribed to a method without an argument? is it just ignored?

cosmic rain
calm talon
#

How do I get the normal of an OnTrigger event?

rain minnow
#

only with OnColliderXXX . . .

calm talon
#

Is there any mathematical trick or?

hard viper
#

what is the normal of an on trigger event even mean?

#

collisions with contact points have normals

#

what does it even mean for a trigger to have a normal? you have a shape inside another

calm talon
#

A line drawn perpendicular against the closest contact point I guess

hard viper
#

there are no contact points

#

because it is a trigger

#

fyi, you can have a non-trigger collider that doesn’t send/recieve forces

calm talon
#

how if I may ask?

#

cause that would fix my issue pretty easily

hard viper
#

colliders have force override settings

#

if you set the layer override to: Send Forces layer mask = 0 (ie nothing), it will send no forces to anything

#

you can do this both in inspector dropdown menu when looking at a collider, or set it via code

calm talon
#

I don't see any such option?

image.png
rain minnow
hard viper
#

weird. here’s what a box collider looks like

calm talon
#

when was the feature implemented?

hard viper
#

idk. it’s a pretty basic feature

#

circle colliders have them too

calm talon
#

for context I'm using 2021.3.28f1

spring creek
hard viper
#

kekw lmao xd

#

that is kind of embarassing, because it's a pretty basic feature lol

calm talon
#

having that rn would remove so much headache

hard viper
#

I'd back up your project, upgrade editor, and see if anything breaks

#

I fuck with layer overrides a lot

#

you can turn off certain layer collisions temporarily

rain minnow
spring creek
#

I have literally never used them haha.

spring creek
hard viper
#

they are useful when you want to give something a little bit different collision properties without defining a whole new layer

#

or when you want to temporarily make something intangible (to force) while still sending collision callbacks

#

for example, you might want a goomba that walks into another goomba, and it knows to turn around.

#

you don't want forces to get involved, because goombas actually can pass through each other (and don't usually make a janky stack without a special case)

#

but you do want the collision callback so they know they touched, to turn around

#

this is a great tsime to use a layer override, and it's a lot easier/simpler than other method

#

make sense?

hi, I need some help with ads mediation / iron source sdk.
has anyone encountered this issue where video and interstitial ads just popup up and close on their own without fully playing on an android build?

version info:

  • unity version: 2021.3.30f1
  • installed ads mediation package through package manager
  • used LevelPlay integration manager to:
  • update iron sdk to latest version (also had this same problem using the v7.2.x)
  • install unity ads adapter

(on Android, you didn't specify platform)

#

i haven't installed the logcat package. will do that and check for errors. thanks for the suggestions! i'm testing on android, will update the original message
update: checked my options, don't keep activities is off

#

For giggles, have you tried testing it in portrait mode?

#

Are you forcing the app to landscape?

sour plume
#

ahh it was because i have auto rotate off. i just tried turning auto rotate on and the ads play properly. yes i forced the app to landscape and haven't tried portrait mode. didn't notice any errors that looked like it was from playing the ad in logcat too. thanks!

I understand that I'm in the wrong channel for this, but is anyone able to help me with an input system issue, i havent gotten a reply in there for 2 days lol #🖱️┃input-system

whole portal
#

Perhaps you guys can help me debug this one. So the issue I have is I was generating my chunks vertically using local Y co-ordinate, which made the chunks disconnected vertically (as in they would look like slices):

float[] blendedNoise = new float[currentBufferSize];
int chunkHeight = GridMetrics.PointsPerChunk(lod);
for (int x = 0; x < chunkHeight; x++)
        {
            for (int y = 0; y < chunkHeight; y++)
            {
                for (int z = 0; z < chunkHeight; z++)
                {
             int index = x * chunkHeight * chunkHeight + y * chunkHeight + z;
                    float heightFactor = (float)y / (float)chunkHeight;
                    blendedNoise[index] = BlendNoise(terrainNoise[index], caveNoise[index], heightFactor);
                }
            }
        }```
And after updating the code to use a world Y co-ordinate, I no longer see the vertical chunks.
```csharp
float[] blendedNoise = new float[currentBufferSize];
int chunkHeight = GridMetrics.PointsPerChunk(lod);
float worldHeight = 256.0f;
for (int x = 0; x < chunkHeight; x++)
    {
        for (int y = 0; y < chunkHeight; y++)
        {
            for (int z = 0; z < chunkHeight; z++)
            {
             int index = x * chunkHeight * chunkHeight + y * chunkHeight + z;
                float globalY = (globalOffset.y * chunkHeight) + y;
                float heightFactor = globalY / worldHeight;  // Calculating heightFactor based on global position
                blendedNoise[index] = BlendNoise(terrainNoise[index], caveNoise[index], heightFactor);
            }
        }
    }```
This is what I was trying to debug, like why it doesn't work anymore ? I can see the vertical chunks being generated in the object hierarchy, but they are invisible in the scene, this sort of points out to an issue either with the noise generation (may not have Y ?) or with the chunk generation, but not sure.
#

Before: All the vertical chunks were disconnected, and I think the issue is because I was using local Y co-ordinates for the height factor.

After: I am now using global Y co-ordinates, which "should" solve that issue, but instead I can no longer see the vertical chunks being generated at all.

Note (the slices you see, are not 1 chunk, it's like 9 chunks or so per slice. So the horizontal chunks generate still fine in both scenarios. It's the vertical chunks that I have issues with.

  • I have a script that is using an audiosource component. They're both on the same object. When i quit, it triggers a sequence of calls starting from other objects' on destroy, which leads to a method that this script has. In there it refers to an uadiosource component, which appears to be destroyed at that point. Other than doing that wasteful null check which is going to occur only ever once during a session, how can i handle this?
lean sail
cold egret
# lean sail You've said 2 things A wasteful null check Itll only ever happen once Which one...

  • By "only happens once" i mean meeting the null check. In all other cases it's guaranteed to return false, and will only trigger during the application quit

  • The thing is not used every frame, but a dozen of times within a single one with large intervals between such "bursts"

  • Ig it's just my perfectionist speaking. I never liked these null checks of unity objects. Thank you regardless

lean sail
#

🤷‍♂️ the issue is that something is unexpectedly null, you need something that conditonally does your logic as long as the object exists. any work around would just be involving an if statement and some bool

I am using an enum with getter/setter. How can I make it show in the inspector?

molten venture
#

I actually want to have the enum in the inspector and call a function if the enum value is changed. Looks like I might need to create a custom inspector for that

cosmic rain
#

Ah, you want to call a function when you change the value in the inspector?

molten venture
#

Yes, I don't really need the get/set but I thought I could use the setter to do that

Custom inspector is one option. Another one is using OnValidate.

hi so im refrancing all my instatiated objects like this spawnedPipes = Instantiate(genTube, cylinder.transform.position, cylinder.transform.rotation);

#

then saying this spawnedPipes.layer = 6;

#

but its not changing any of them

#

where have i gone wrong

earnest snow
#

Hello, I have using the Application.persistanceDataPath to save my data. In the docs said the data will not be delete after an update but it does when I update my app

#

UtilityState.Instance.SavePath = Application.persistentDataPath + "/" + LessonData.lessonId;

#

the LessonData.lessonId will be a folder contains some others file

#

but after an update, the folder "LessonData.lessonId" is being delete

hard viper
#

given that code, it looks like you only keep one reference to a pipe, and it gets overwritten the moment another gets instanced

cosmic rain
jaunty sundial
earnest snow
hard viper
#

I would keep a List<GameObject>

#

when are you changing the layer? right after it is instanced?

#

i would go:


…
GameObject pipe = Instantiate(………);
pipe.layer =6;
pipeList.Add(pipe); ```
#

in general, whenever I instantiate something, I always try to log a reference to it in case I need to access it later

How do i tell what my raycast hit

leaden ice
#

check the Raycast docs for examples of this

jaunty sundial
leaden ice
#

make sure you are doing it the same way as the docs indicate

#

you likely have something out of order or in the wrong place

#

note that argument 5 is NOT where the raycast hit param should be

#

so it's definitely an issue of the wrong order

#

Your IDE should give you something like this too to help^

Hey, I have a question about Zenject.

So I have a class

public class Test
{
  public Something _Smth;
  public Foo _Foo;
  private int Id;

  public Test(Somethnig smth, Foo foo)
  {
    _Smth = smth;
    _Foo = foo;
  }
}

and I install it like this

 Container.RegisterNewInstance<Foo>();
 Container.RegisterNewInstance<Something>();

then I have a list List<Test> Tests

What I want to do is somehow make a for-loop that will create and add Test to Tests list. I want to make sure that _Smth and _Foo are installed using Zenject and I want to pass Id when I create this object. From my understanding of zenject if i do var test = new Test() it wont work cuz Something and Foo wont be installed right?

#

How can I do this?

scarlet viper
#

Is there no oneliner to create a list and add one element to it?

var somelist = new List<Part>(part);

#

You need to actually use one of the raycast overloads that provides the RaycastHit

#

this one isn't going to contain any information

#

you just made a blank one

#

So when you try to do hit.collider.tag it's an error, since your hit is empty, hit.collider is null

Short-lived allocations will get marked as leaked if they don't get freed soon enough

hollow jacinth

Wdym?

heady iris

URP has two different renderers.

I believe ShadowCaster2D (which is in your stack trace) is from the 2D renderer.

leaden ice
#

Oh god I had no idea about this. They've managed to make the render pipeline thing even more confusing 😵‍💫

heady iris
#

i mean, sort of

#

i find it straightforward enough

#

the render pipeline is all the machinery; the actual renderer slots into that

#

By default a 3D URP project will use the standard universal renderer

#

I believe the 2D renderer was experimental until recently

#

I need to try it. I've never actaully made a 2D game in Unity...

#

(i can't draw)

hollow jacinth
#

I am using with the 2D Renderer I think

#

And I am using ShadowCaster2D on some of the GameObjects

heady iris
#

What version of Unity are you using, and what verison of the URP package are you using?

#

(you can find the latter in Window > Package Manager)

hard viper
#

render pipeline is pretty confusing ngl. Just a few days ago, I couldn’t figure out why one thing wouldn’t render. Problem: Random checkbox

you also can't do something like

heady iris
#

Right.

hard viper
#

it’s like if pos was 4, and now you are trying 4 += 6. That doesn’t make sense

heady iris
#

It's like doing transform.position.x += 1;

heady iris
hard viper
#

my point is: you don’t have a reference to the vector. you have a vector

#

at least I think he does

static matrix
#

thats so wierd
maybe it just doesn't work with structs

heady iris
#

you can never assign to a foreach iteration variable, ever.

#

no type will permit this

static matrix
#

but I can assign to members?

heady iris
#

Sure.

#

That's not the variable.

hard viper
#

i assume if it is reference type, you could modify the underlying variable, but not assign to it

static matrix
#

but not if its a vector3 iterator

heady iris
#

You can't assign to a value type member because you can't assign to the variable.

heady iris
hollow jacinth

If you want to mutate the contents of the array, write a normal for loop

quick elbow

I have a gameobject (let’s call it A) that is a child of another object (called B). When A is moved around, the parent B stays in place. I want to periodically update B (the parent) to be at the position of the child. When this happens the child moves because it’s local transform is relative to the parent, so I essentially need to reset the child transform to zero it out. When I do this, I encounter a split second where the child A snaps to a new position relative to B, and then snaps back to be at the same spot as B. How do I update B’s position and A’s transform so that it happens seamlessly?

This is the tech stream version of unity, so it's more likely to have bugs than the LTS

#

It's probably not a big deal.

hollow jacinth

the LTS does not work properly for me

#

I started the project as legacy 2D

and then switched to urp

and from then weird things started to happen

like the memory leaks

#

Logging is very expensive

#

Unity has to generate a full stack trace and write a bunch of stuff into the console

quartz folio
#

Stack trace generation can be very expensive at times, the logging itself is cheap in comparison

thick socket
#

the error only happened once at the launch of the game

#

surprised that would drop from 200fps->120fps

If it happened once then the logging of the error itself is unrelated to the ongoing performance issue

at least in deep profile, Debug.Assert normally mostly costs the string.concat for the error messages I generate. Which need to be generated to call the function

colliders, also make sure you move with rigidbody and not translate

leaden ice
#

or generate it procedurally

give them colliders and dynamic rigidbodies

wouldn't that be the same ?

if you are making mazes, you want procedural generation

Is there a way to check if an object has already been released before trying to release it?

#

imo this error shouldnt be happening anyway

#

but it still annoys me

# 
void OnTriggerEnter2D(Collider2D collision)
    {
        var tag = collision.transform.tag;
        if ((tag == "Fighter" || tag == "Player") && tag != shooterTag)
        {
            Fighter colFighter = collision.GetComponent<Fighter>();
            colFighter.Damage(dmg);
            //Debug.Log("Pool Release called");
            fired = false;
            StopDestroyAfterDelay();
            pool.Release(this);
        }
        else if (tag == "Wall" || tag == "Floor")
        {
            fired = false;
            StopDestroyAfterDelay();
            pool.Release(this); **Line45**
        }
    }
leaden ice
#

before releasing

#

or add another bool

thick socket
#

once it "releases" it shouldnt be able to have collider interact with anything anymore?

# 
void ReturnBulletToPool(Bullet bullet)
    {
        //Do Particle Explosion
        EffectType effect = EffectPooling.instance.effectPools[bullet.effectType].Get();
        effect.transform.position= bullet.transform.position;
        bullet.gameObject.SetActive(false);
    }
#

should immediately be SetActive(false) once released

thick socket
#

I tried this and still getting the error...its a lot less

#

but still occasionally

# 
void OnTriggerEnter2D(Collider2D collision)
    {
        var tag = collision.transform.tag;
        if ((tag == "Fighter" || tag == "Player") && tag != shooterTag && fired)
        {
            Fighter colFighter = collision.GetComponent<Fighter>();
            colFighter.Damage(dmg);
            //Debug.Log("Pool Release called");
            fired = false;
            StopDestroyAfterDelay();
            pool.Release(this);
        }
        else if (tag == "Wall" || tag == "Floor")
        {
            fired = false;
            StopDestroyAfterDelay();
            pool.Release(this);
        }
    }

#

is it just the other code might be too slow

leaden ice
# 
        else if (tag == "Wall" || tag == "Floor")
        {
            fired = false;
            StopDestroyAfterDelay();
            pool.Release(this);
        }```
#

you had this
which is still potentially releasing it without checking if fired was false already.

scarlet viper
#

How to generate a random string that could work as an ID ?

thick socket
leaden ice
thick socket
#

still not sure why fired would need to be checked since it should only release

#

and the disable the object

leaden ice
#

this can happen if you have multiple colliders or are overlapping with multiple things simultaneously

thick socket
#

ah ok thanks, forgot that it could collide with 2 things same frame 😄

thick socket
#

so for having an object "redirect/richochete" when hitting a wall/floor its easy, you just multiply X by -1 for wall, Y for -1 for floor

#

issue Im having is how do you tell its a floor or wall on something that has a floor and wall side

#

ex) a square has a side that would be wall and top would be floor

leaden ice
#

the code is simpler, and the math will work for any surface orientation

#

not just straight vertical/horizontal surfaces

thick socket
#

that makes sense...I say while googling what a surface normal is and how its found 😄

leaden ice
#

you can get the normal vector from any Collision callback or from any raycast-like physics query

thick socket
#

thats really nice

#

I can just do like collision.normal to grab the normal

leaden ice
leaden ice
thick socket
#

so I would do

        Vector3 newmovement= Vector3.Reflect(movement, collision.normal);
leaden ice
#

yep

thick socket
#

assuming my walls aren't bumpy that will work much better thanks 🙂

#

might have some weird interactions if the walls are bumpy lol

leaden ice
#

definitely

#

as you might expect from bouncing off a bumpy wall

thick socket
#

oh darn

#

I can't use OnTriggerEnter2D for this type of thing

thick socket
#

or will I have to make it on a collider instead of a trigger

rigid island
#

you can still get a normal with a raycast

thick socket
#

raycasts and I dont get along very well 😄

rigid island
#

they're very powerful tool

thick socket
#

oh for sure

#

I just tend to spend a lot of time debugging them whenever I have to use one

rigid island
#

yeah gizmos are life saver for that

thick socket
#

at least it doesn't take my scripts 20s to save anymore

#

even with gizmos trying to bug fix like 5x takes a few minutes for a 2s code change

#

😦

rigid island
#

.collider

simple egret
#

You need to get a contact point

rigid island
#

i think

#

oh yea

thick socket
#

should I just grab the first one?

simple egret
#

collision.GetContact(0).normal - this cannot fail since there's always at least 1 contact point (at index 0) for a collision

thick socket
#

_enemy.detectorWallNormal = collision.contacts[0].normal;

simple egret
#

That creates an entire array to get the first element, don't

#

Use GetContact

#

There's both

#

GetContacts is useful if you want to get all of them

thick socket
#

lol

rigid island
#

walks away in shame

thick socket
#

bye navarone's messages 😄

simple egret
#

Now it looks like I'm talking to myself

rigid island
#

lol thought you were using Collider2D because triggers

thick socket
#

then I wasn't cause I was told I can't use triggers to get the normal

rigid island
#

yea true, what I mentioned you can raycast to the collider to get the normal

#

its how i fake my bullets sometimes

public class ColliderDetector : MonoBehaviour

            Physics2D.IgnoreCollision(myCollider, collision.gameObject.GetComponent<Collider2D>(), true);
        }
    }
#

why is this not disabling the collision between collider and platform at the end when they hit

#

The Debug.Log is firing

simple egret
#

Collision already happened at the time IgnoreCollision is called

thick socket
#

it might even leave, fly away, come back and collide again

rigid island
thick socket
#

the enemy thats moving around

rigid island
#

do you only have 1 collider / are you sure ur grabbing the correct collider?

thick socket
#

prety sure to both

#

however I just saw I can have the collider2d itself just ignore the layer in inspector so I'll probably do that instead 😄

#

I think this should work

rigid island
#

oh thats some new new

#

i never seen that

thick socket
#

same lol

heady iris
#

yeah, it's relatively new (in 2D physics)

thick socket
#

I didn't want to have to go into physics and mess with adding layers and disabling for everythign

rigid island
#

imso used to collision matrix, this looks handy

thick socket
#

on the downside

#

it doesn't appear to be working lol

rigid island
#

they still collide?

#

weird

thick socket
#

yep

#

very fun

#

not at all making me mad 😄

rigid island
#

time to debug..
maybe Print a little more info on what ur actually hitting / layer name n all that stuff at runtime

#

something must be off

I think is calledhttps://en.wikipedia.org/wiki/Bresenham%27s_line_algorithm
or would it be Digital Differential Algorithm? sorry If its not helpful

Bresenham's line algorithm

Bresenham's line algorithm is a line drawing algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points. It is commonly used to draw line primitives in a bitmap image (e.g. on a computer screen), as it uses only integer addition, subtraction...

I want to share some functionality between Mono and non-Mono scripts, how do I do it? I can only derive from one class...

If it's just a bunch of static methods you need, you could even make it a static class

orchid bane
# leaden ice If it's just a bunch of static methods you need, you could even make it a static...

How should I name a class which has methods like these?

        #if UNITY_EDITOR
        if(!Application.isPlaying) Undo.RegisterCreatedObjectUndo(gameObject, "create scene object");
        #endif

        else GameObject.Destroy(gameObject);
#else
        GameObject.Destroy(gameObject);
#endif
    }```
leaden ice
#

EditorObjectManager or something? Idk

leaden ice
#

they already take a parameter for the object they are intended to manipulate

orchid bane

I just can't choose a good name

leaden ice

Choose an ok name and you can change it later

UndoHelper

But the second method works without undo too

I am trying to change a URP RenderFeature settings through code. I have the RenderFeature referenced and when I do renderFeature.GetComponent<RenderObjects>() I get a NotSupportedException.

#

Should I reference the RenderObjects directly?

dusk apex

Maybe show the full error

molten venture
# 
NotSupportedException: Specified method is not supported.

#

Hmmm, I am not even using visual scripting at all

leaden ice
#

You might have accidentally imported the wrong type somewhere

#

I would:

  1. uninstall Visual Scripting if you're not using it
  2. double check your using directives in Chaos.cs
molten venture
# 
RenderObjects ro = renderFeature.GetComponent<RenderObjects>();```
leaden ice
molten venture
#

I tried referencing it directly and it is working

dusk apex
#

Apparently render feature doesn't support your specific method call which seems to be get component

leaden ice
#

we don't know what type renderFeature is though

#

which is very important

#

seems like it might be a ComponentHolderProtocol whatever that is

#

some Visual Scripting thing

rigid island
molten venture
#

It's ok. Referencing it through the inspector works but for some reason it doesn't update on the scene, only in the inspector. Is there some update call that should be done on the UniversalRendererData or ScriptableRendererFeature in order to have them update in game?

rigid island
dusk apex
#

You'd probably want to define work and doesn't work as well

#

Your prior stack trace suggests this is an on validate callback which wouldn't change unless the inspector value changes

molten venture
#

renderObjects.settings.overrideMaterial = someMaterial;
The material is being changed in the inspector on the RenderFeature, however it is not being changed in the scene. When I do the same thing manually, through the inspector, it does get updated in the scene.

#

(RenderObjects is a built-in RendererFeature in URP)

rigid island
#

it would help if you sent at least the full script so we get an idea where everything is called

molten venture
#

I will write the relevant parts as the script has lots of stuff in it.

[SerializeField] private ScriptableRendererFeature SSTextureFeature;
[SerializeField] private RenderObjects renderObjects;
[SerializeField] private List<Material> screenSpaceMaterials;

private void OnValidate(){
  if(/*a certain enum value has changed*/){
    UpdateScreenSpaceEffect();
}
}

private void UpdateScreenSpaceEffect()
    {
        //currentScreenSpaceEffect holds the current value of the enum mentioned above
        if(currentScreenSpaceEffect == ScreenSpaceEffect.None)
        {
            SSTextureFeature.SetActive(false);
            return;
        }
        SSTextureFeature.SetActive(true);
        //line 140
        renderObjects.settings.overrideMaterial = screenSpaceEffectMaterials[((int)currentScreenSpaceEffect) - 1];
    }

But I don't think it really matters as it does do what it is supposed to do and when it is supposed to do it, the issue is in the fact that the scene is not updating with the new settings.

#

It only updates with activating/deactivating the render feature but not with updating the material

swift falcon

Got it. I just need to set the ScriptableRendererData as dirty

It finds most of them but not all. It seems instead of choosing all the cubes it passes through, it ignores the cube where the intersecton was smaller

    void Draw3DGridLine()
    {
        Vector3 start = origin.position * 10f;
        Vector3 end = target.position * 10f;

        Vector3 delta = end - start;
        int steps = Mathf.Max(Mathf.RoundToInt(Mathf.Max(Mathf.Abs(delta.x), Mathf.Max(Mathf.Abs(delta.y), Mathf.Abs(delta.z)))), 1);

        Vector3 step = delta / steps;

        List<Vector3> points = new List<Vector3>();

        for (int i = 0; i <= steps; i++)
        {
            Vector3 point = start + i * step;
            points.Add(point);
        }
    }

Anyone knows?

I am casting a ray down to the floor to check what type of layer the floor has however the out hit returns null each time. SUper confused. The layer is set up and I can see the ray being cast and passing through the floor

leaden ice

#

It passsed the if statement

leaden ice
#

Looks like you're inspecting hit before the raycast ran

wicked river
#

that fialed

leaden ice
#

right if the raycast function returned false that means the raycast didn't hit anything

#

so hit will not be populated

#

There is no point for this

Screenshot_2023-09-28_at_6.46.08_PM.png
wicked river
#

I get that, but it should be hitting somethig

leaden ice
#

hit.collider will NEVER be null. The raycast can only hit objects with colliders

leaden ice
#

perhaps your raycast is in the wrong place, or the object you expect to hit has no collider

#

or the collider isn't where you think it is

#

Debug.DrawRay is a common tool to debug raycasts

wicked river
#

Well, The collider is a mesh collider . It's the floor. The ray passes through the floor

#

The debug.draw is in the images I sent

#

you can see the line

leaden ice
#

unclear if the raycast is starting above the floor or not

#

or if it's ending below the floor

#

it could be entirely above or below the ground

wicked river
#

I starts aboce the floor ends below

leaden ice
#

there's no perspective

leaden ice
#

Show where the collider is?

#

and what layer it's on

#

etc

Hello! Quick question: Is it bad practice to move a kinematic rigid body inside of update?

#

It's usually taken care of by the publishing platform. Steam would try to update the game automatically if you uploaded a new build for example.

If you don't use any publishing platform, you'll need to implement some kind of launcher that does it for you.

strong geyser
#

the "VRTopHat" and "VRSunglasses" are both example 3d models that don't exist in my project.

#

so maybe that's the problem?

#

im a dumbass soooo lol

It looks like the string uses the gameobject name:

"Every body part on the player has a child named something with "Cosmetics", under those you put the models of the cosmetics you want. You have to rename the object to the ID of the cosmetic, let's say you put on a hat with the ID "VRTopHat" then under the Cosmetics child of the head you put your model and name it "VRTopHat", like this:"

#

Theres a picture at the bottom of the repo you linked

#

Do you HAVE an object named "Left"? Is it a child of an object called "Cosmetics"?

I've been trying to understand how picking a random item from a list of weighted values work, because i think it'd be the best option for picking rooms in a dungeon generation algorithm.

If i have say, 3 items, call them A, B, C. and all of these items have a weighte value of 10.

I assume then each item has a... 33.3% chance of being picked?

heady iris
#

sum up the weights, then pick a random number between 0 and the sum

#

iterate over the list, subtracting each item's weight from the random number as you go

#

if the number reaches zero, return the item whose weight you just subtracted

delicate zinc
#

hmmm...

#

ok lemme see if i can implement this right

#

cuz i've been working on a custom collection for this kind of stuff

# 
float startWeight = _rng.RangeFloat(0, TotalWeight);
            
for(int i = 0; i < _items.Count; i++)
{
    startWeight -= _items[i].weight;
    if (startWeight <= 0)
        return i;
}```
#

methinks this should work then.

#

heck

#

i mean, that didnt really answer my question regarding the probability

#

because currently only one item is being picked constantly

#

i assume its because all three items have the same weight?

heady iris
#

how are you creating that _rng object?

delicate zinc
#

rng is a custom Random number algorithm i found on github, cant recall where

heady iris
#

why are you using a custom pseudorandom number generator

Xoroshiro128Plus i think is the algorithm it used?

delicate zinc
#

mainly because of that

heady iris
#

so is every other PRNG

delicate zinc
#

Unity's global

heady iris
#

System.Random can be constructed with a seed

#

You can also save and restore the state of UnityEngine.Random at will

#

by accessing Random.state

#

Show your code. If you're not getting random results, I suspect you're deterministically seeding your RNG

#

you can sanity check your RNG by logging a random integer

delicate zinc
#

will do

heady iris
#

I was doing that two days ago while tracking down an rng bug

delicate zinc
kindred vessel
#

Aight. I just need this: How do I authenticate as a service account via some Unity library?

heady iris
delicate zinc
#

my bad

#

worth mentioning that the seed i use for the WeightedCollection on my current attempt is basically taken from another instance of my RNG, which itself the seed is set to the current DateTime.Now.Ticks

#

converted to ulong

heady iris
#

i would suggest just using Random.Range to rule out a problem with your RNG

#

I see that you're logging startWeight already, though

#

if you have three items of weight 10, then you should see a total of 30

#

with random values between 0 and 30

#

here's how I did this, by the way

delicate zinc
#

yeah, 50 + 50 + 50, 150

#

so thats correct

#

lemme checkout something

#

well

#

the first line is just the start weight, and its always the same value

#

so... ugh

#

ok lemme see if removing that custom rng andd replacing it with System.Random works

#

yeah my RNG is just fucked

#

guess i'll just use System.Random

#

and subclass it if need be

heady iris
#

you won't need to subclass it

#

just construct an instance and you're good

Hello, why my v and p matrix are not zero but the inverse matrix of their multiplication are? Ah, nothing. It's because I set translation to 0

delicate zinc
# heady iris just construct an instance and you're good

letting you know (because i belive i should always say what my outcome was for future people's sake), turns out the custom rng class i have is fine, i just used a constructor that basically creates a copy with the same rng states

#

so... yeah, of course the same outcome was happening when all of them where on the same state instead of different ones

heady iris
#

Ah, that would do it

#

I noticed the copy constructor

delicate zinc
#

indeeed

#

that's the one i was using

#

now i'm just using the already existing rng class and generating a new seed from it, instead of using the copy constructor

I started a new project a week ago. I was able to build and run it without issues. But now, I Build and Run, it goes into script compilation, and shortly stops building, doens't output any logs at all. No build completed, or failed logs, nothing. Just stops. Doesn't write anything to the build folder either. I tried "Clean build", same thing. Anyone else had these issues? Why would it silently stop and not say anything.

I'm having a weird desync with connecting NavMesh to root-motion movement. If I plug the desired velocity parameter from the agent and convert it to local space into my animator paraneters, the agent starts acting weird. It doesn't path around objects, sometimes it moves away from its target, it may walk out of the NavMesh, or it simply stops as if it reached its destination. I've also tried getting the vector from nextPosition to the agent's position, normalizing it, applying my speed multiplier, and then plugging those values into my animator paraneters, it doesn't desync but the model vibrates due to nextPosition being enlarged so much after being so small. Has anyone done something like this able to help me?

potent sleet
wheat spade
#

I have two parameters in my animator, x and z, that control the blend of the animations. The navMesh coords are in world, so I have to convert it to local. Local vs world isn't the problem, I've tested them both.

I did use velocity, it's in world coords.

Yeah, give me a sec though.

{
    //Only redo the path sometimes (every 1/15 of a second default)
    if (updateClock <= 0)
    {
        agent.SetDestination(target);
        updateClock = 1 / navMeshFrames;
    }
    else
    {
        updateClock -= Time.deltaTime;
    }

    //Get the vector from the nextPosition property.
    //Doesn't work.
    /*
    Vector3 worldMovement = agent.nextPosition - owner.transform.position;
    worldMovement = worldMovement.normalized * speed;
    Vector3 localMovement = owner.transform.InverseTransformDirection(worldMovement);
    */

    //Smoothes the movement. Doesn't work either.
    //Code from https://docs.unity3d.com/2021.1/Documentation/Manual/nav-CouplingAnimationAndNavigation.html
    /*
    float smooth = Mathf.Min(1.0f, Time.deltaTime / 0.15f);
    smoothMovement = Vector3.Lerp(smoothMovement, localMovement, smooth);
    */

    //This doesn't work.
    agent.speed = speed; //Doesn't do anything for now since speed isn't changing.
    Vector3 localMovement = transform.InverseTransformDirection(agent.desiredVelocity);

    animator.SetFloat("MovementX", localMovement.x);
    animator.SetFloat("MovementZ", localMovement.z);

Hello guys I have a game that consists of a main game and a few mini games that are triggered from it in the same scene. Currently my games are badly coupled and require a lot of editor references. I want my mini games to basically be "plug and play". If I add a new one into the future I want it to be easy. Can you recommend a design pattern that I can look into and implement to solve this problem?

in my above script, i'm wondering if there is a better way to handle this part

    private void Update()
    {
        if (spinDuration > 0)
        {
            spinDuration -= Time.deltaTime;
            Spin();
        }
        else
        {
            UpdateLayout();
        }

    }

where its not always calling UpdateLayout every frame.. that's bad for performance right?

            spinDuration -= Time.deltaTime;
            Spin();
            layoutUpdated = false;
        }
        else if (!layoutUpdated)
        {
            Debug.Log("layout updated");
            UpdateLayout();
            layoutUpdated = true;

Hey all, I am instantiating an object at a target destination. Once instantiated, I am attempting to animate its position on the Y axis, however, it seems as though the animator is resetting the object's x and z positions also. How can I stop the animator from overriding the x and z positions?

cosmic rain
worn oasis
#

It's not

cosmic rain
#

If you only need to animate the visuals, have a separate object with the visuals animated.

worn oasis
#

If I try to remove them, all 3 positions are removed

#

hmm, I'll give that a try

cosmic rain

Game logic should be separated from visuals.

static matrix
#

ugh trying to set up pathfinding in a procedural world will be the death of me I swear

hexed pecan
static matrix
#

I just don't know how to do it thats all

hexed pecan
#

Use the navmeshcomponents package and bake the NavMeshSurface(s) from a script after your world is generated

#

Assuming it is 3D

static matrix
#

the problem is it keeps being generated
its infinite
I've tried having a surface on each chunk but then enemies can't cross chunks

hexed pecan
#

Not sure why it would generate infinitely 🤔

#

It generates when you call the bake function

static matrix
#

no the world does
it just has like 12 chunks around the player loaded at any given time

#

so I would need to bake again and again I would think

#

I had gotten it to work somewhat but it caused freezes every time it baked
which isn't good
before I had gotten it to work without freezing but then enemies couldnt cross chunks

hexed pecan
#

Ah I see. Didnt come across that issue since I gen my world on start

#

Generating them asynchronously would be good but I dont think that is possible at runtime

static matrix
hexed pecan
#

Not sure, maybe you need to generate navmesh links between them

static matrix
#

yes
I was trying to find a workaround

static matrix
hexed pecan
#

All I can think of right now is using a single large navmesh that you update when chunks are created. Maybe limit the area though

#

I'll tell you if I find some solutoon, I might need to solve it myself too

static matrix
#

yeah I couldn't figure out how to do that when async
that got the pathing working totally but caused a freezeframe every time a chunk spawned, which ofc I can't have

#

I've tried doing custom pathing scripts or having enems that don't really need pathing but those don't work for everything

I've tried using Application.targetFrameRate because I wanted to see how my game behaves at low framerates. Everything behaves well until I set the target framerate value to something lower than 60. If the framerate is below this value, the game starts to look jittery and rigid bodies become unstable both when moving and when colliding with other objects. All these changes have been observed while running the game inside the editor. I did not create a build of the game in order to see how the "final product" behaves. Is it normal for the game to behave this way when running at under 60fps?

hexed pecan
#

And/or abusing deltaTime

#

If you do things correctly, the framerate shouldnt affect physics, except when the physics loop struggles and reaches the max time step

#

Rb jitter can be caused by a few things so you should show some code, how you move things etc. And it could be a camera issue too

hexed pecan

#

Is there an event raised when a NavMeshAgent collides with another one?

vivid remnant
#

The scene includes a character that is controlled by the player. The character has a CharacterController component. There are also "interactable" objects such as boxes and barrels that have rigid bodies but I never add forces to them. The Rigidbody components are only there so the boxes will behave appropriately when they fall of something. Lastly, there are doors and elevators that have kinematic rigidbody components. Let's focus on the elevator for a moment. If a box is placed on that elevator, it goes up and down with the elevator as you would expect but if the framerate is under 60, the box starts jumping as the elevator goes up as if the colliders are going through each other. I tried moving the elevator both by using Transform.position as well as Rigidbody.MovePosition() and the behaviour remains the same at under 60fps.

potent sleet
leaden ice
neon plank
#

When a NavMeshAgent collides with another NavMeshAgent it doesn't produce a OnCollisionEnter AFAIK, after all, they aren't colliders

#

So I guess it may be another method, but don't know which one

potent sleet
neon plank
# potent sleet

(You didn't specify to add Colliders so I thought you mean Rigidbody + NavMeshAgent)

heady iris
#

The rigidbody might not behave correctly if the NavMeshAgent is directly moving the object around

#

Although, from my experience, it's fine

potent sleet
#

Never had major problems with constraints on, but don't quote me on it

#

its how I make my agents push physics doors too

heady iris
#

why do you freeze the position and rotation?

#

is it non-kinematic?

potent sleet
#

I prob should, but I didn't want to deal with the whole collision matrix not detected between certain types

#

dynamic has more choices

vivid remnant
# leaden ice This is the main drawback of a CharacterController based character. If you need ...

The character controller can wait. :)))
For now, I would like to understand why the elevator and the boxes start acting weird when the framerate drops below 60. They both have rigidbody components(kinematic for the elevator / non-kinematic for the boxes). I tried moving the elevator in FixedUpdate() using Rigidbody.MovePosition() and in Update() using Transform.position and the behaviour still occurs.

Just because you're using FixedUpdate doesn't mean you're doing things in the right order at the right time

I have an issue with my character controller which I don't know how to fix. If I stand still, the jumping animation plays normally, from start to end. However if I am walking and try to jump or running and try to jump, the jumping animation plays 2 times in a row but before the first time even finishes, like only a few frames then it stops.

Normally when waking or running, the jumping animation should only play once, from start to finish, just like it does when I am idling. I have checked my animator settings and they are set up correctly I think, also checked the animation transitions and they look normal, so the issue has to be with the code.

If someone can have a look and tell me how to fix it I'd appreciate, code is here: https://pastebin.com/0qtWKP0j

we would need to see your animator controller

leaden ice

heady iris
#

You must be going from Walking to Jumping to some other state and back to Jumping again

potent sleet
#

also you could kill some mess by using blend tree for idle/run/walk

#

using float for speed control

leaden ice
#

the radius number stays the same

#

but the effective radius will change

whole portal
#

And I only press spacebar once, as you can see it's jumping two times but only when walking or running.

#

And the jumping animation stops prematurely as well when walking or running.

heady iris
#

does your Jumping state have an exit time on its exit transitions

whole portal
#

No

dawn mauve
heady iris
#

all bools

#

are the blend times different between the different transitions that enter the Jumping state?

#

It seems like it's spending a long time blending between Running and Jumping

dawn mauve
#

It could also be that the jumping animation is looping.

whole portal
potent sleet
#

you have two bools together probably

#

oh you have no exit time for Jump, how do you set it back to false?

heady iris
#

This is wrong. You should only exit the "Jumping" state when isJumping is false.

image.png
#

isWalking and isRunning remain true even when you're jumping

potent sleet
#

I typically have a state for IsGrounded where my player is mid-air if not grounded

heady iris
#

So it's rapidly transitioning back and forth.

#

Keep your animator in the Jumping state until isJumping is false

#

isIdling gets set to false when isJumping is true

#

That's why that worked fine.

whole portal
heady iris
#

add another condition

#

you can have many conditions

#

they must all be true for the transition to occur

#

I looked through some forums in the meantime and discovered that If I want the coroutine to behave as it is was code running inside of FixedUpdate(), I should use WaitForFixedUpdate() instead of WaitForSeconds(Time.fixedDeltaTime).

#

I made the change and now the box has the desired behavior when on the elevator.

vivid remnant
potent sleet
#

the result will always be choppy/inaccurate collisions

heady iris
#

MovePosition does respect physics...

#

are you thinking of Transform.Translate ?

potent sleet
#

Yeah mybad I confused it with MoveTowards

#

i need my coffee

heady iris
#

that'd be Vector3.MoveTowards

#

i wish you could use the static methods like instance methods

#

foo.MoveTowards(bar, 1);

potent sleet
#

yeah apparently my brain this morning, thought MovePosition & MoveTowards were the same 👨‍🦯

#

hmm maybe the positions are off

#

As you can see, the method that moves the elevator is a coroutine. When the player activates the elevator, the coroutine starts. I don't want the player to be able to activate the elevator again until the coroutine that is already running has finished its job.

#

The InteractiveMove method simply checks if a coroutine is already active in order to prevent the player from starting another one.

hexed pecan
vivid remnant
leaden ice
vivid remnant
leaden ice
#

unless you are doing coroutineActive = null; at the end of the coroutine

hexed pecan
#

Yeah, coroutine reference will not nullify itself when it finishes

vivid remnant
#

I know.

#

InteractiveMove is called inside of the Interact method which makes a coroutine null in case the criteria are met.

#

But you are right, @hexed pecan, I was using WaitForSecond(Time.fixedDeltaTime) when I should've been using WaitForFixedUpdate().

potent sleet
#

nice

vivid remnant
#

I still have some work to do with the way the box behaves when it's carried around in order to make it look better but I'll figure something out.

# tranquil canopy this is the prefab

very simple:

  PipesMovement newPipe = Instantiate(pipePrefab);
  newPipe.pipesController = this.pipesController;

what?

leaden ice
#

= is used to assign values to variables in C#

tranquil canopy
#

yep

#

but, what does that "this" mean?

leaden ice
#

It means... this!

#

Because we're in the PipesController script, it means the PipesController

#

The one on which the code is running

#

it's like "me"

heady iris
#

this exists inside of any non-static method

#

because non-static methods, by definition, must be called on a specific object

#

and that object is this!

tranquil canopy
#

ohhh, much clear... and wich is the difference betwen [serializefield] and make the data type public?

leaden ice
#

serialization is just how data is copied around in Unity for the inspector and with Instantiate, etc.

heady iris
#

public and private are access modifiers. They determine who is allowed to see that member.

public means that any type can access the member. private means that only the declaring type can access it.

Unity automatically serializes public fields. You can use [SerializeField] to indicate that a field should be serialized (e.g. if it's private).

#

(a "member" is anything inside of a class or struct: fields, methods, properties, etc)

tranquil canopy
#

so, in a few words, its the same?

heady iris
#

They are not the same. They both happen to serialize the field.

#

A private field cannot be accessed by any other class.

I have a kinematic rigid body platform which moves using MovePosition. I have a dynamic rigidbody player that I want to parent to it, so player moves in the platform's reference frame.

I can make them move together if I use Translate or transform.position instead of MovePosition, but that doesn't seem right, because that would screw with other collisions, right?

I have tried fixed joint2D and some other joints to try to connect them, but the joints I tried that do make the two things move together ALSO block the player's movement (which is done by forces). Any advice?
