[naive summit]

My bad, accidently put an . there

[somber nacelle]

yes

[naive summit]

Thank you :))

[exotic reef]

raycasting wont work , as some portoin of cuboid can possible still go inside terrain , bcz it only ensures hit.point be above terrain not the whole cuboid , and about boxcast i dont know what that is , i will see how to use it, thxx

[somber nacelle]

i guess you don't know about the existence of math to determine where in relation to that hit.point you would put the object?

[exotic reef]

as far as i know , hit.point gives a vector of position x y z of the point of intersection of ray and the collider

[somber nacelle]

yes

[exotic reef]

but that wont work , bcz only the transform.position = hit.point , not ensuring if the whole bounds of cuboid are above terrain , bcz terrain is not flat

[somber nacelle]

again, do you not know that math exists? you know you can use the bounds of the collider to determine how far you need to offset the position from the hit point, right?

[dusk apex]

Don't directly set the object's position to the hit point but rather set it to that with some offset.

[exotic reef]

ok , how to calculate the offset tho?

is it something like , the bounds of overlapping collider - hit.point for X and Z axis?

[fossil temple]

yo someone tryna help me

😊

[somber nacelle]

Don't Ask To Ask

[somber nacelle]

the distance from the pivot point of the object to the point on the bounds where you want the object to rest is the offset

[somber nacelle]

yes, you can ask for help in here like literally everyone else

[somber nacelle]

the thing is though, is that you have to ask a question if you want help

[somber nacelle]

it's a link. click it and read it

[fossil temple]

ip grabber

phisher

stay away pal..

ight na seriously tho @somber nacelle U tryna help me with sum

[somber nacelle]

it's not even my website, genius. and it is a permitted link

[somber nacelle]

no

[fossil temple]

why :/

:(

[somber nacelle]

you haven't even bothered asking a fucking question

[fossil temple]

ight my bad

[dusk apex]

Basically instead of asking if someone's available to help, just ask your question. If someone who is on the server feels like they want to answer/help you, they will.

[fossil temple]

how do i make my player die after contact with object

[dusk apex]

Break the problem down.
Define contact. Define die.

[fossil temple]

ight so

[somber nacelle]

or just like google the question

[dusk apex]

For example: On collision enter and Destroy

[fossil temple]

when red touches white

i want white to

die

and game over screen happens

also sub question: do i make game over screen first then add the contact on death thing

[dusk apex]

Without knowing anything about your setup (physics or no physics), there isn't much that folks can suggest without fishing for more information or simply designing your game.

[fossil temple]

i dont really get it

what more information do i provide

[dusk apex]

Are you using physics?

How are you evaluating contact?

[fossil temple]

im ngl what is physics

ohh

i searched

ye i am

and i am evaluating contact by when on screen red touches white

[dusk apex]

Alright, so you need to break the problem down and consider how you're going to be actually evaluating "contact" between objects.

[fossil temple]

alr just lmk this

since I want to make it so that when red comes in contact with white a game over screen shows up and users get option to restart or exit, do i make the game over screen first

[dusk apex]

Your eyes can perceive it but how is your application going to be evaluating contact?

[fossil temple]

when like two coordinates are in the same place

[dusk apex]

So.. with rigid body physics, character controller, collider cast, other physics casts or ?

[fossil temple]

rigid body

[dusk apex]

Google Unity Rigidbody collision
There ought to be plenty of tutorials on this. After acquiring this feature, determine how or what you'd define as "die".

[fossil temple]

bro i aint gon lie

u the most useless person i met in my entire life

i deadass just had a conversation w a brick wall

[night storm]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html this works maybe

[fossil temple]

thx

[lean sail]

You're expected to know the basics in the general channel. If you cant google, well the problem lies between the screen and the chair.

[fossil temple]

u think i would come here to ask before i googled 😭

[lean sail]

Yes, many beginners do.

[night storm]

surely if u googled u would have found something..

[fossil temple]

nah not anything that works

[lusty zephyr]

😀 idk if you know a lot about tech, but IP grabbing is basicly useless. The only thing what's dangerous about it is that they know your location.

[spring creek]

That seems to be the standard, yes

[fossil temple]

i was joking bro 😭

[lusty zephyr]

I know you were

I'm not living under a rock

[spring creek]

Hopefully this was a joke too

One thing is when jm moving from top of ladder to bottom its not going on the launder(ladder is slanted so i want it to roll it over it). Its kinda launching itself and landjng luckily

Also the turn its making from red platform to ladder is instant, I want it to be seemless

[green wharf]

i have a tps character and im using a state machine, should i create a state for my character's aim state or should i check if im aiming in other states (if anyone can help i can send you the project, because something feels wrong)

the character's movement system changes while aiming

[naive summit]

Hi, im working on a door raycast script and im pretty new to this raycast stuff so i may not understand completly but logically why isnt this working.

public class DoorRaycast : MonoBehaviour
{
    MyDoorController mydoorcontroller;

    public void Awake()
    {
       mydoorcontroller = gameObject.GetComponent<MyDoorController>();
    }

    public void Update()
    {
        if(Input.GetKeyDown(KeyCode.E)) 
        {
            RaycastEvent();
        }

    }

    public void RaycastEvent() 
    {
        RaycastHit hit;
        if (Physics.Raycast(transform.position, transform.forward, out hit, 100f))
        {
            mydoorcontroller = hit.collider.gameObject.GetComponent<MyDoorController>();
            if (mydoorcontroller != null) 
            {
                mydoorcontroller.PlayAnimation();
            }
            else 
            {
                Debug.Log("NotFound!");
            }
        }
    }


}

When e is clicked it sends an raycast and if the object that was raycasted has MyDoorController script then the PlayAnimation() Inside it is called, or Debug.Log is called. However when i click E on the door nothing shows up in the console at all

[dusk apex]

Place a log and see if the method was called

[knotty sun]

to start with add a debug if the raycast fails

[naive summit]

I have debugs in both scripts and for some reason nothing shows up in the console

[knotty sun]

well it wont if the raycast fails

[dusk apex]

You need to debug at a higher scope

[naive summit]

I think i found the faulty one.

public void Update()
{
    if(Input.GetKeyDown(KeyCode.E)) 
    {
        RaycastEvent();
        Debug.Log("E was clicked!");
    }

}

It never debugs anything in the console

Bug the code looks correct so why is that

[knotty sun]

the object or sript is disabled

[dusk apex]

Is the object inactive? Is the component disabled? Did you save?

Are logs enabled in the console window?

Have you tried turning Unity off and on again?

[naive summit]

Alrighties i fixed the E problem, so now E is debugged, Raycast gets sent out successfully but the other script is not found

I have a GameObject called DoorPivot, and inside it a GameObject called Door. Now the DoorPivot has the script but it doesnt have a box collider, while the Door itself has the Box Collider but not the script, could that be whats causing this?

Since i thought because that Door is a child of DoorPivot it automaticly is detected too

[spring creek]

Please don't be a bully to people that are actually helping people

[dusk apex]

Consider logging or drawing the ray to verify if it should indeed be hitting

[naive summit]

I found it, it was just that i had to give the pivot itself an Box Collider and it cant have an box collider because the pivot doesnt move, only the door does. So istead im just making a third door controller script which will be in the door itself then call the Pivot to play animation

[exotic reef]

there is a reason why windows and Browser bring updates every now and then , Grabbing IP is a stepping stone for an attack , I use Google Chrome , and it has some network vulnerabilities now also , I got a browser hijacker with a keylogger too , by just opening a fishy redirected ad link , not even downloaded anything .
I talked to 3-4 more people who opened that website , they got it too . The best guess is , the hackers have used my IP adress to connect to my network and find network vulnerabilities in chrome , and installed a malicious plugin in chrome and other browsers , after that my browser had this " Managed by your Organisation" , with 2 russian malware pugins installed in my edge browser .
So never underestimate hackers and always use an adblocker .
Although rare , but u can be a victim of an exploited vulnerability of a browser ( altho they are patched quickly in most cases)

[lusty zephyr]

You clicked on a link which gave more than your IP.

[exotic reef]

what do you mean ? i didnt understood?

[lusty zephyr]

I'm just saying that an IP grabber can't do stuff like that. It just gets your IP adress. Nothing more. You clicked on a malicious link which had way more stuff added

[exotic reef]

i am just saying grabbing your IP can have implications like these, if you are really unlucky .

[spring creek]

What implications?
Because the stuff you listed above is not because of your ip

[exotic reef]

a hacker who has your IP can use various techniques to compromise your network and gain unauthorized access , If they manage to connect to your device,
altho to my knowledge its only limited till browsers hijacking, they cant install an exe file tho

[exotic reef]

the hacker must have grabbed my ip adress first and then tried to connect to my network to exploit any existing chrome vulnerability or maybe any general network vulnerability . Altho its all a guess noone knows how he did it .

[spring creek]

It was certainly not from your ip

[lusty zephyr]

You can't do that with an ip

It's like your local address. if we have it, then we can't teleport to you

[dusk apex]

Even if you had the IP address of some random individual, you'll likely not be able to exploit them unless you're aware of some application that they're using and if you're given consent to launch the application without constraint.

[exotic reef]

thats what i said , it cant launch any application , but it can still affect browsers , because browsers are connected to network .
Everything connected to your network is still vulnerable , your data , your online games and all

[knotty sun]

sorry, no. you are wrong

[spring creek]

No offense, but you have a profound misunderstanding about what an IP address is and what it can do

[static matrix]

do static attributes persist between scenes, assuming they aren't tied to an object

[dusk apex]

If you've got active x and java script enabled with no constraints and whatnot, then perhaps your computer could be compromised if you accepted and launched whatever web app embedded in the site requested you to.

[knotty sun]

even if they are tied to an object, static variables always survive until the end of the application domain

[dusk apex]

More than likely though, you've contracted a virus or malware through installing some component/app or have given permission you weren't aware you were giving.

[rigid island]

static attributes?

[static matrix]

public static int, so on and so forth

[rigid island]

ohh a field, yeah as SteveSmith mentioned they will

[simple egret]

In C# an attribute is something else, eg. [SerializeField] is one

(these cannot be marked as static)

[exotic reef]

I am certainly not a cyber security expert , but i know that grabbing IP address is the first step to any cyber attack , it can tell a hacker which system to attack ,
I have experienced it myself so i believe it in it , and i have read some blogs from Microsft , nordVPN and This forbes blog also i am attaching , i am not trying to convince u or so , but i believe in this, bcz i suffered a whole day bcz of it and always now use an adblocker

[spring creek]

Your issue... had nothing to do with the ip. Simply having the ip will not allow what happened to you

It is also NOT necessary for what happened to you. You likely downloaded a virus

Lastly, someone can get your ip in many ways

[static matrix]

if I assign a field to a prefab (like the value is a script attached to a prefab) can I change that? like is it an instance I can alter

[latent latch]

discord has your ip address

watch out

[static matrix]

every website does

thats how websites work

[exotic reef]

Okay lets close this convo . was just trying to tell my experience , i certainly dont have sufficient knowledge to justify myself more than this

[static matrix]

unless you use a vpn

is this in any way related to unity btw?

[exotic reef]

no

[dusk apex]

So you'd reference some class with your field and you'd be able to create/modify an instance. What's the concern?

[spring creek]

You are spreading harmful misinformation.
I definitely would appreciate it if you stopped

[static matrix]

ah, so I have to rewrite it then?

ah whatever
ill figure it out

[exotic reef]

this is not misinformation , its true and happened to me , and as far as i know my explanation is correct , u are not counterattcking me with points . thats why i am not contnuing this convo anymore , again no offense to this . please lets believe what we believe .

[lean sail]

Believe what you want, that doesnt change how attacks work

[night moss]

If I have two empty gameobjects in the same position acting as "connecters" how could i find other connecters starting from a connecter? Hope I made myself clear

[exotic reef]

ok

[knotty sun]

just so you know, for future reference, your public IP address has nothing to do with your computer. It is actually is linked to your router

[spring creek]

I believe the truth. You are objectively wrong. And that is ok, but please stop

What you are doing is akin to saying clouds are made of fish, and you have tons of people saying no they aren't, and your response is that "well I saw a fish"

It's hard to argue with something that obviously incorrect without just saying you are wrong

[rigid island]

you would need some type of query maybe physics or just position based

[lean sail]

Realistically you wouldnt want to do this. Youd be comparing positions, you should have a more defined system of what connected objects are

Cant use physics if they're empty

[vagrant blade]

Can we move on from this IP thing, it's not even Unity related

[static matrix]

lets say I have public Ammo myAmmo and I set that value to a prefab gameobject that has an Ammo attached
then, in some other script, I say player.myAmmo.damage += 1
when I fire the gun, hence instantiating myAmmo, is the damage increase there?

[night moss]

You just gave me an idea, thanks

[dusk apex]

Prefab would be an asset you'd want to reference to spawn. If you're needing to keep track of persistent data, perhaps consider a Singleton manager

[rigid island]

keep stored stats in a POCO

[fleet tide]

Sorry, can you explain me more ? I'm not sure to understand completly

[dusk brook]

var x = GameObject.Find("Hidden Layer Node 2/Input value");
Debug.Log(x);
var y = x.GetComponent<Text>();
Debug.Log(y);

Somehow y is null here?
x is logged as Input value (UnityEngine.GameObject) so I'm not sure what's going wrong here

I just want to grab the text elment

[dusk apex]

Was there an error?

[dusk brook]

This is the input value so it is a text element... Is the Text class referring to the legacy Text element?

[dusk brook]

No, just y being null

[fervent furnace]

dont use find/get component if possible ie you can reference it
use TMP_Text

[rigid island]

Text is old yes

[dusk apex]

That likely means x isn't what you think it is or that it really doesn't have said component

[rigid island]

Text is def not TMP_Text

also no reason this should be a find. As @fervent furnace mentioned use a serialized field

[dusk brook]

Ah TMP_Text does the trick. Should've just answered my own question :p

[dusk brook]

I'm building a graph (essentially) so have to dynamically grab many elements, hence the find

What is the time complexity of Find?

Should I store all the objects or is it fine to keep re-calling

[rigid island]

its extremely slow and makes decent amout of garbage, thats all i know

[fervent furnace]

O(number of gameobjects in hierarchy)

[dusk brook]

👍 Cheers guys

[rigid island]

oh god this site

Debug.DrawRay maybe ?

[somber nacelle]

if you're on 2022+ use the physics debugger

if you are on a version older than that, you'll need to draw the raycast with debug.drawray or something

[rigid island]

https://youtu.be/zzFv6kp-XHA 😮

[green wharf]

im using unity editor 2022.8.3f1 but cinemachine 3 is not available

[rigid island]

2022.8 ?

[green wharf]

2022.3.8f1

my bad

[rigid island]

did you check package manager?

[green wharf]

i did

[somber nacelle]

pretty sure you can manually install it by name in that version. but is there a particular reason you are using such an old patch of 2022.3?

[rigid island]

hmm maybe you could manually change manifest

[green wharf]

a friend suggested this ;-;

which is the best version other than unity 6?

[somber nacelle]

then just update to the latest patch if you don't have any real need to be on that specific patch version

[green wharf]

ok thanks

[somber nacelle]

2022.3. but you're just on a really old patch for it

the latest 2022.3 version is 2022.3.31. you are currently on a patch that came out in august of last year, which is also before cinemachine 3 was actually released from beta

[green wharf]

thank you 🙂

ty

[somber nacelle]

have you actually enabled the physics queries in the physics debugger?

[rigid island]

it looks like this for me 😦

nothing is changed in the code, if you're using physics queries the code is not important to draw debug them

#archived-code-general message

this video will show you how you can see them in the playmode with built in analyzer
(window -> analysis -> physics debugger)

[somber nacelle]

if you do not see any raycast after enabling the queries in the physics debugger then you need to check your conditions to make sure that they are actually allowing the raycast to be fired

[rigid island]

can you show it where you enabled

but yeah now im starting to lean towards your code being sus

if (isShot == true && ammoClipLeft > 0 && isReloading == false)

ook good. Just double checking

maybe throw some debug.logs in there and see if that section is even being hit

[somber nacelle]

do you see anything if you also enable Cast there?

[rigid island]

which part of the shooting?

Ohh

you know what you need that

thats your raycast

Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

[somber nacelle]

what do you mean by that

[rigid island]

the ray is working

[somber nacelle]

so you do see it then?

[rigid island]

don't

I think you're assuming its supposed to come out of the gun

if you want ray to come out of the gun, you need to set the ray start and direction from your shooting point

just an empty gameobject

call it (firePoint) or some shit

ideally its child of the gun and if its child of camera, they should have correct look direction

make sure (blue) arrow points forward in local mode (not global)

then you can just do
ray = new Ray(firePoint.position, firePoint.forward)

[heady iris]

it's very common to use empty game objects as reference points

game objects don't have to have any components on them (other than the Transform)

that's not jank at all

[gray mural]

I'm saying I would consider creating a specific class, which might store the essential data for the merged ScriptableObjects. This class can also have a static method, which takes a List of the ScriptableObject as its parameter, and updates the necessary variables

public class Spell
{
    public Spell(...) { ... }

    public static Spell Merge(List<SteamoxSO> steamoxSOs) => new(...);
}

//
public List<Spell> spells = new();

//
spells.Add(Spell.Merge(selectedItems));

[rigid island]

whats jank about it ? its pretty common

do note it also depends on the game, some games the ray does not come out of the gun just the visual FX

Counter-Strike is a good example of this

(the weapon ray always fire from center of screen)

[heady iris]

I need a heap with a decrease-key operation. Any suggestions for a library?

I'm looking at implementing a Fibonacci heap, and it's mildly scary looking

certainly compared to a binary heap

C#'s PriorityQueue does not have a decrease-key operation (and it's not available anyway)

I might just insert duplicates. This is for A*.

[leaden ice]

What is "decrease-key"?

[heady iris]

It lets you reduce the value of an existing item in the heap

so in A*, you might discover a cheaper path to a node that you haven't visited yet

you store all of the unvisited nodes in a heap

you can either push a duplicate element with a lower value or decrease the value of the item already in the heap

I'm...not using a heap at all right now, so maybe I should do that first 😅

[leaden ice]

Would a SortedList be good enough

Just remove and re-add an element when you find a cheaper cost

[heady iris]

adding items into a SortedList is O(n), which can be pretty punishing if you're adding and removing items at roughly the same rate

heap insertion (and removal) are both logn

[leaden ice]

Sorted dictionary?

[heady iris]

(and fibonacci heaps apparently get amortized O(1) for insertion too, scary)

a SortedDictionary is a binary search tree, which is also worse than a heap for this purpose

I completely forgot I wasn't actually using a heap yet, so I'm going to do that first lol

[viscid stump]

hey guys can i have some help? for some reason im putting a text on my screen in unity and its not showing up in game view

also in scene view its all blury so im not sure if im doing something wrong?

im a beginner by the way

[heady iris]

this is not a code problem

[viscid stump]

hm , can i show you a picture of show my screen over a muted call perhaps?

[fleet tide]

I see ! But create a JSON file for each spell created and in it write every stats and stanza used is a good thing ?

[leaden ice]

Share screenshots in #📲┃ui-ux

[viscid stump]

getting it handled in unity talk rn thank you tho!

[gray raft]

what will be the best method to make these lazers?

[rigid island]

Line Renderer maybe ?

they seem pretty simple

I used a similar approach drawing with a Raycast, you just need a good material

[fleet tide]

It's good !

I created sript for generate and use JSON (JSON contain the list of stanza)

Now i have a good thing for storage, initializing and use spell 🙂

[night moss]

Amazing, that idea you gave me works perfectly, thanks!

With that I solved a problem i was trying to fix for 3 days

[lean sail]

Glad it works, although what I said was barely an idea 😅 just told you to make a system for it

[night moss]

Guess your message made my last neuron work for a few seconds 🤣

[quaint crypt]

how do I rotate a rect transform around it's center? regardless of where the pivot / anchors are. I've tried iconRT.RotateAround(iconRT.TransformPoint(iconRT.rect.center), Vector3.forward, (rotated) ? 90 : 0); but it still rotates around the top left corner of the RT and not the middle.

edit: nvm im stupid

[vapid harbor]

Is it possible to fork unity and contribute to it/modify?

[somber nacelle]

the engine itself is closed source, except for the c# bindings. there are open source packages though. i'm not sure if they accept contributions though

[heady iris]

at least, packages whose source you can look at; they aren't FOSS-licensed

[hollow dust]

does anyone know any good melee combat tutorials? for punching?

[chrome trail]

So, as you can see from the GIF, I have a problem where the mesh renderer appears to be very selective when rendering the areas that have been dug out. What I've been able to deduce so far is that this is caused by the fact that, rather than the ground being a single 10x10 mesh it's 10 1x1 meshes linked together. However, I don't want to fix this by making a single 10x10 mesh since it's not going to scale well with the project. So how do I solve this problem without doing that?

[rancid frost]

is it normal for memory to not be released in editor?
ive destroyed game objects containing mesh data, but yet the amount of memory that belongs to mesh according to profiler does not decrease

Nothing is being shown but yet 1.8gb in meshes?

[cosmic rain]

1. Asset unloading happens on scene unload. You can force unity to unload unused assets manually by an API call.
2. If it's a generated mesh, you might want to destroy it as well, before destroying the object.
3. Editor might behave differently than a build.

To clarify point 2, assets are not unloaded or destroyed by the GC as objects do(when all references to it are lost).

And mesh data is considered an asset.

[rancid frost]

I see

I know GC would not be called on some unity objects, so i ttried clearing out mesh before deleting, but even that did nothing

Strangely enough, it seems the editor frees the memory if you need more

[cosmic rain]

How did you do it?

And is that during play mode?

[rancid frost]

negative, im in editor

[cosmic rain]

Maybe DestroyImmediate(sharedMesh) instead.

[rancid frost]

copy

let me see

sec, let me restart scene and test

picture 1) Empty scene
pci 2) scene after work
pic 3) scene after clear.

didnt work

[cosmic rain]

Using DestroyImmediate?

Maybe try this then
https://docs.unity3d.com/ScriptReference/EditorUtility.UnloadUnusedAssetsImmediate.html

There's also a possibility of you having a leak. If you generate several meshes during the session and reassign them where previous meshes were assigned without destroying the old ones.

[upbeat furnace]

hey so I am making a wave type system however for some reason when the next wave comes it refers to the previous wave sorta like this:
Wave 1 > Wave 1 > Wave 2

{
     //Calculates the number of enemies in a wave to spawn (this is set in the Wave scriptable object)
     for (int waveNumber = 0; waveNumber < currentWave.NumberToSpawn;)
     {
        int enemytoSpawn = Random.Range(0, currentWave.EnemiesInWave.Length);
        int enemySpawnPoint = Random.Range(0, spawnpoints.Length);

        Instantiate(currentWave.EnemiesInWave[enemytoSpawn], spawnpoints[enemySpawnPoint].position, spawnpoints[enemySpawnPoint].rotation);

        waveNumber++;
        enemiesAlive++;
     }
}```

[cosmic rain]

Wdym by "refers to the previous wave"? How do you know that?

[upbeat furnace]

so I use waves as scriptable objects so I can customise each wave and well when just having 1 of them in the waves stay at 0 for some reason but when I add Wave 2, it repeats Wave 1 then goes into wave 2... Sorry if that doesn't make sense xD

[cosmic rain]

How do you know that? How are you confirming that that's what happens. And what does it even mean "to go into wave x"? How is it expressed in code?

[upbeat furnace]

when I used
roundNum.text = "Round: " + currentWave.ToString();
instead of
roundNum.text = "Round: " + waveNumber.ToString();
I got the name of the scriptable object so when the 1st wave started I could see which wave was initiated, then once all the enemies are done it should have initiated the timer which it did then move on the the next wave but it seemed to have initiated Wave 1 instead of 2.

I used this code to increase the wave

{
    
    //increase wave
    if (waveNumber + 1 < waves.Length)
    {
        currentWave = waves[waveNumber];
        currentTime = 10f;
    }
    else if (enemiesAlive > 1)
    {
        //stop spawning once limit is reached for the wave.
        stopSpawning = true;
    }
}```

[cosmic rain]

So, to put it simply, waveNumber doesn't have the expected value?

[upbeat furnace]

pretty much yeah

[cosmic rain]

You should debug it then whenever you're modifying the value

[upbeat furnace]

thats pretty much what I'm doing though I will say it's weird when I take out waveNumber++; the engine crashes xD

[cosmic rain]

As well as when the it is used

[cosmic rain]

Must be resulting in an infinite loop

[cosmic rain]

I don't see any debugs in the code you dhared. Are you stepping through the code via the debugger?

[cosmic rain]

If you mean removing the ++ here, then yes, that results in an infinite loop

Use proper debugging methods and you'll figure it out in no time. You're supposed to be able to debug if you're asking in this channel

[upbeat furnace]

I usually take out the debug logs before posting xD

[cosmic rain]

Don't do that. That's the worst thing you can do to people you're asking help from

[upbeat furnace]

yeah thats my bad xD just picking up programming again

[cosmic rain]

Share the code with the debugs and the result in the console.

Since it might be a lot of code, share it all in one code paste link.

[sharp blaze]

Hey guys I'm having a little problem

So I have an overlay canvas and inside of it I have an Image of my character. The character in the UI is a parent of another Image component that is basically acting like an accessory, player can move it around. Later when player confirms the accessory on the character, local ui position of the hat/accessory image is saved and I want to apply that to my character in the world space.

Basically, original character is a SpriteRenderer in the world space and he also has the accessory spriterenderer transform as a child.

How would I convert the screen space local position to the world space local position?

Character sprite is the same in the image and the spriterenderer

[cosmic rain]

You should debug the waveNumber value. Logs that debug the same thing don't really help at all.

[static matrix]

this is really cool, how is this done

[chrome trail]

The mesh vertices are pushed down

That's basically it

[static matrix]

how does one do verticies editing?

[cosmic rain]

You need to know the relation between your screen space positions and world space positions. If you have 2 points of reference that are equivalent in screen space and world space you can do that. For example, if you know the vector from your character pivot to it's head both in world space and screen space.

[upbeat furnace]

this is after the

{
     //Calculates the number of enemies in a wave to spawn (this is set in the Wave scriptable object)
     for (int waveNumber = 0; waveNumber < currentWave.NumberToSpawn; waveNumber++)
     {
        int enemytoSpawn = Random.Range(0, currentWave.EnemiesInWave.Length);
        int enemySpawnPoint = Random.Range(0, spawnpoints.Length);

        Instantiate(currentWave.EnemiesInWave[enemytoSpawn], spawnpoints[enemySpawnPoint].position, spawnpoints[enemySpawnPoint].rotation);

        Debug.Log(waveNumber);

        enemiesAlive++;
     }```

[cosmic rain]

Where?

[cosmic rain]

Looking at this it's always a unique value.

Also, you should make your logs meaningful like that: "on wave incremented wave number: x" or "on waves reset wave number: x". Just numeric values can make it very confusing especially if you're debugging it in multiple places.

[upbeat furnace]

yeah I need to remember that my bad xD
But yeah I think I know what it's tied to since there are 5 unique values, I believe it is tied to the amount that is spawned which is kinda strange I think I need to untangle my code

[heady iris]

did you recalculate the bounds of the mesh?

I'm not sure if that happens by itself

[chrome trail]

Yeah, I was told in another server to try doing that

[heady iris]

it looks like the meshes are vanishing once the original bounds of the mesh (which is flat ground) go off screen

[chrome trail]

Haven't done it yet though

[heady iris]

Show the code that modifes the mesh

[upbeat furnace]

Okay I found the issue turns out if I have just Wave 1 this code won't initialise:

{

    if (waveNumber + 1 < waves.Length)
    {
        waveNumber ++;
        currentWave = waves[waveNumber];
        currentTime = 10f;
        SpawnWave();
        Debug.Log("Wave: " + waveNumber);
    }
    else if (enemiesAlive > 1)
    {
        //stop spawning once limit is reached for the wave.
        stopSpawning = true;
    }
}```

[latent latch]

Fellow SO enthusiast using them for waves

my mate is like "why" and I'm like "what if I want to reuse them later??"

[cosmic rain]

Makes sense. 0+1 is not smaller than 1.

Not quite sure what that condition is testing.

[vocal breach]

can someone help me i changed this little character i made from using character joints to configurable joints and the character fell through its self

[upbeat furnace]

so after doing this:

{

    
        waveNumber ++;
        currentWave = waves[waveNumber];
        currentTime = 10f;
        SpawnWave();
        Debug.Log("Wave: " + waveNumber);
    
    
}``` 

I get the following:

[vocal breach]

oh nvm i just had to turn xyz motoin to limited and turn collision on

[sharp blaze]

Thanks! I did it 😄

[cosmic rain]

Yes, because after reaching the last element and running this code, it would try to access an index that is out of bounds.

Make sure you don't run this code if you reached the last element

[upbeat furnace]

Well atm I am trying to do is start the wave then use the wave to begin the spawn i figure that way it's easier to debug

[cosmic rain]

It doesn't matter what you're trying to do. You should handle out of bounds correctly. Imagine you have 5 boxes with apples, them you try to take out an apple out of box 6(it doesn't exist). What would happen?

[hardy anvil]

Hey guys I'm trying to make a button object that has a cool down in between presses, but I am unsure on how to do so.

[cosmic rain]

yield keyword can only be used in coroutines(IEnumerators to be correct), not in regular methods.

[hardy anvil]

How can I use the coroutine and onMouseUpAsButton together?

[spring creek]

Also, it is yield return
Then you can pass a new WaitForSeconds (or cache one)

[spring creek]

StartCoroutine

[upbeat furnace]

It'd continuously run the code over and over? Ngl I feel dumb xD

[cosmic rain]

You'd crash the world. You can't access something that doesn't exist.

[upbeat furnace]

true xD well I guess I am sort of making progress now

[hardy anvil]

is this how it should be? And if so where do i put my WaitForSeconds() because its only waiting to run my code. Its not really a cooldown.

[cosmic rain]

Yes, that's a coroutine. Now a cool down would need some more logic.

[spring creek]

This would delay the Farm call by clickCountdown time

Cooldown could be handled with bools around a wait call. Check the bool before allowing the coroutine to start again (just one simple way to do it)

[hardy anvil]

Thanks I got it working with just a cooldown bool

[rigid island]

you're checking cooldown twice for the same thing ?

also coroutine would've been better than Invoke not sure why you changed it lol

 void OnMouseUpAsButton()
 {
     if (farming) return;
     StartCoroutine(Farm());
 }
 IEnumerator Farm()
 {
     farming = true;
     farmerManager.Farm(level, Color);
     yield return new WaitForSeconds(cooldownTime);
     farming = false;
 }```

[hardy anvil]

lmao thanks for the help. I am new and am still learning. Just to clarify, the "if (farming) return;" part makes it so the code under it ("StartCoroutine(Farm());") doesn't run when farming is true?

[rigid island]

exactly, it "returns" early out of the function

since the function is void (does not return anything) you can just return no value

[proper badger]

Is there like a list of good practices for making a game more moddable

[arctic steeple]

why doesn't the value out equals 6 but 5 ?static void Main(string[] args)

    {

        int value = 5;



        Console.WriteLine("Value before increase: {0}", value);



        IncreaseValue(value);



        Console.WriteLine("Value after increase: {0}", value);

       

        Console.ReadKey();

    }



    static void IncreaseValue(int value)

    {

        value++;

    }

[somber nacelle]

because of the difference between value types and reference types. also this is a unity server, not a general c# server

[arctic steeple]

I'm sorry but can you explain a bit more into that, I will send them to a c# server later

[somber nacelle]

there are beginner c# courses pinned in #💻┃code-beginner
you should probably start there

[indigo verge]

I'm pretty sure I could implement this one of two ways, but I wanted to ask you guys for advice and thoughts on this.

I want to use a State Machine to control combat in my Turn Based RPG, and my plan is that each action is its own series of States, OR its own state machine.

This means, for example, when you hit "Sword Swing", the game will load a state machine that asks for a target in one state, moves the player to that target, then performs the attack, making the character perform the state machine's states in sequence.

Would it be better to have Scriptable Objects that just hold a list of states, which are loaded into a State Machine attached to the character, or have a Scriptable Object that holds an entire State Machine, and the player merely switches between those?

[thin aurora]

All numeric types are value types. Classes for example are reference types.

When it comes to value types, the variable is passed by value and not by reference. This means you make a copy of the value and pass it over to the method. You will not edit the actual initial value because of this

Other instances of value types are structs, Vector2, Vector3 and Quaternion, for example. Your IDE usually differentiates value types from reference types when they implement a struct type rather like a class type (like the ones mentioned here)

You can fix your code to pass a reference type. Just change the method signature to this:

static void IncreaseValue(ref int value)

And the call to the method:

IncreaseValue(ref value);

For clarification, the reason why this difference exists is performance. Especially with vectors the difference is very big when computing values as the reference must be cleared otherwise. This is done with garbage collection and it can impact your game significantly if left done improperly.

[leaden solstice]

So.. your states are only sequential then what is the difference between list of states and state machine?

[indigo verge]

Honestly, not much, which is why I ultimately ended up just using a system to switch thhe states in the state machine.

[leaden solstice]

I assume your character can only have single state across all actions

[indigo verge]

Only one state at a time, yeah

[leaden solstice]

So character should be something that knows what state they are on

but if your action needs to override something about states

Action should have some way to hook it ig

I mean I wouldn't really think this as state machine tho

Just list of tasks maybe

[indigo verge]

Some of those tasks need their own logic and behaviors, though, and need to be able to backtrack, since combat actions need to be able to request UI input and wait for it, and be able to be backed out of with the cancel button and things like that.

[leaden solstice]

Sure, but those logics are defined in each states right?

What's actually running those state doesn't seem that important in this case

[fallow quartz]

I made an options menu so the player can change resolutions and quality, but when i start a game and then go back to the main menu this settings reset, any idea why?

Btw this reset is only at a visual level, but if the res is changed it stays, only happens with the HZ

[pastel patio]

I'm trying to use BatchRendererGroup to make my own "MeshRenderer" for most of the two most recurring meshes (Cubes & DoubleFacedQuads)

However what troubles me a lot is how I'm meant to sync the transformations of the Transform's transformations with the BGR instances

How am I meant to sync all the data? I could try SetData and calculate the offset for each individual movement however... Well, I can bet that the performance implications of SetData is nothing like that of just copying stuff into an array

I can't use GraphicsBuffer.LockBufferForWrite either cus Unity crashes if I create the buffer for BGC's instance data with that flag on

So the last resort in that case would be SetData once every frame, it would seem

Since there're prone to be many cubes moving... SetData once for each cube's movement is really bad, Setting once per frame for everything might be costly too but maybe it's not as bad

[pastel patio]

Nvm overlooked something- In one of the articles they recommend making one such buffer on the cpu

Still needs to perform SetData every frame... Hopefully it's for some reason extra performant copying the whole buffer over

Hi, I have a reasonably big unity project with around 30 scenes, and made a big refactoring process, the thing is, i have added a lot of serialize fields, i want to see for each game objects if he has some fields with none values inside in all scenes (or minimum one scene)

Hi, my plan in the function MoveChildToParent is to delete the desired item from the string, but for some reason it randomly deletes another item
https://gdl.space/enoyuqojeq.cs

[heady iris]

I don't understand what you're asking for

Are you looking for fields that have nothing assigned to them?

[slate imp]

I have added serialize fields to some scripts, and since they are used in a lot of scenes and objects i want to edit all of them and not forget any, also since i changed multiple script i could miss a script

the idea is to have some tools that will find each object that have empty fields

[slate imp]

yes

[heady iris]

I've written code to do this, actually

it's still very rough, but maybe you can use it

[slate imp]

i would love to have it

[heady iris]

https://gdl.space/idiyidabob.cpp

This is most of the code. You call ReferenceValidator.ValidateOneObject with any object, as well as an optional Unity object as a context for the log items

it also takes a visited hash set. you can use that to remember which fields you've already alerted as being null, so that if you validate many objects, you won't get duplicate warnings if they all reference the same object that has a missing field

Here's an example of how I used it in my code

[ContextMenu("Validate References")]
public void ValidateReferences()
{
    HashSet<object> visited = new();

    ReferenceValidator.ValidateOneObject(this, this, visited);
    ReferenceValidator.ValidateOneObject(defaultBrain, this, visited);
    ReferenceValidator.ValidateOneObject(defaultLocomotion, this, visited);

    foreach (var module in GetComponentsInChildren<Module>())
        ReferenceValidator.ValidateOneObject(module, this, visited);
}

notice how I'm passing the same visited hash set to everything

The validator will stop when it sees a class from a different namespace. I did that because third-party components had many fields that could safely be null, and I didn't want to have to go modify them and add my [MayBeNull] attribute

For each null field, it logs the path it took to get to the field. The log message's context is the closest unity object

If it went into a prefab, clicking the log will just highlight the prefab. Running the validator with the prefab open (sometimes) highlights the component properly

If you want to validate objects in scenes, you'll need to open the scene and then use FindObjectsByType or something similar to scan for the component you're interested in

Unity moment

[fallow quartz]

How unity handles toggles to make the image inside dissapear?

[gray mural]

Yeah, I suppose, this is what you'd usually do for this

[gray mural]

Great, make sure this all is managed by a Singleton. Also, make sure each Spell has its own unique name e.g. Spell 1, Spell 2 etc., which can also be adjusted by the player

[gray mural]

How does it make the Image disappear?

• Are you talking about how it makes its background a bit more transparent? It reduces the Color's alpha.
• Are you talking about it changing the sprites? It... changes the sprites.

[fallow quartz]

right now if i go to another scene and come back

the toggle is always activated (which is what i want if the screen is fullscreen)

but even if my screen is windowed

the toggle is activated

[gray mural]

Alright?

[fallow quartz]

wdym by alright hahaha

[gray mural]

I don't seem to get your question

[fallow quartz]

the toggle is used to change between windowed and fullscreen. When i click it the image inside dissapears so only the borders are left. I want the image inside to be on if the gameis fullscreen and to be off if its windowed

The problem comes when i activate windowed mode, which leaves the image inside off

but if i go to another scene and come back

even tho im still in windowed mode

the image is activated again

[fleet tide]

yes ! Thanks for the help ^^

about this sorry

Do u mean about mobile?

[gray mural]

Yes. The image inside you're talking about is a Checkmark. Simply reverting your condition fixes the issue.

[fallow quartz]

 {
     // Comprobar si los valores de la resolución están almacenados en PlayerPrefs
     if (PlayerPrefs.HasKey("ResolutionWidth") && PlayerPrefs.HasKey("ResolutionHeight") && PlayerPrefs.HasKey("RefreshRate"))

         int width = PlayerPrefs.GetInt("ResolutionWidth");
         int height = PlayerPrefs.GetInt("ResolutionHeight");
         int refreshRate = PlayerPrefs.GetInt("RefreshRate");

         // Establecer la resolución guardada
         Screen.SetResolution(width, height, Screen.fullScreenMode);
         Application.targetFrameRate = refreshRate;
     }
 }```
why my fps doesnt cap at my HZ chosen in the dropdown for the resolutions?

[leaden ice]

Time to use Debug.Log to check if this code is running and with what refresh rate

[fallow quartz]

yeah i already fixed it but i still have one last problem, sometimes (Random) when i go into a scene and i come back i get always 600x480 resolution

[leaden ice]

Again - Debug.Log is your friend

[rigid island]

so whats the problem exactly?

[gray mural]

Well, probably, because that's what your width and height are

Also I don't think there is a need to check for all 3 strings being in PlayerPrefs, as you shouldn't access one of them without having the other two. Am I right?

[fallow quartz]

im on 1920x1080, and sometimes i get reset to 600x480 and others to 1920x1080

[gray mural]

So that's your width and height, as I have previously assumed?

Why don't you consider printing it?

[fallow quartz]

i cant do that on a build

[gray mural]

If in the build, print the text directly on the screen

[fallow quartz]

i sent the build to a friend, when he opens it the new playerprefs i added to the code should be created on his computer?

cause they are not getting created

[gray mural]

Yes, the PlayerPrefs is created on the device the game is played on. You shouldn't expect the PlayerPrefs, which exist on your device, also exist on the device of the other person.

They should be created if you do this via code. The shouldn't if you don't.

[fallow quartz]

ok so the problem is that from time to time the bug occurs which after changing back to the scene of the main menu the screen gets automaticc biggest size

like it happens maybe 1/10 times

If i change res, execute level 1, go back to the main menu scene and check the res sometimes it gets automatic screen size

[rigid island]

time to learn json

[gray mural]

Do you understand hexadecimals?

[gray mural]

I don't think I can give you a solution without more information on setting and getting your PlayerPrefs provided. You gotta put some prints to see what's actually hapenning first

[gray mural]

Not entirely sure what you mean

[fleet tide]

In fact, they have unique name , its just to short for show it but i will work for have something else to show spell

[gray mural]

Then you should consider making the text smaller or the objects wider. You can also put ... at the end of the name if it's too long.

name:     The great spell of Water
display:  The great spell o...

I explained

I think i will remove the name and only display an image but if player place his mouse on it, he will see the name

For now, i just try to use and setup animation

Good luck!

[slim trail]

I want to stop bullets from bouncing enemies

[spring creek]

Bouncing OFF enemies, or making the enemies themselves bounce

Assuming the latter, it would depend on how movement occurs.
You could make the enemies kinematic,
or add a larger trigger area around the enemy and detect then destroy the bullets before they actually collide,
Or disable collisions between the enemy and bullet layers and use spatial queries instead

Just depends on what you want

[gray mural]

You want trigger Colliders. This way, the bullets are going to go thru the enemies, but it shouldn't matter, since in this case, I assume, they are meant to be destroyed immediately when the collision appears.

[slim trail]

Bouncing OFF enemies

[spring creek]

Ok, then destroy it when you collide

OnCollisionEnter

[slim trail]

I tried to do that, but it doesn't detect collisions

[spring creek]

Do one of the two objects have a dynamic rigidbody?
Do both have colliders, and NEITHER are a trigger?

[slim trail]

eee

but you said it SHOULD be trigger

[spring creek]

No, I did not

If you want to use OnCollisionEnter, then neither can be a trigger

If you want to use OnTriggerEnter then exactly one must be a trigger

[slim trail]

so @gray mural sayed that

[spring creek]

He said that as a suggestion for using OnTriggerEnter

Which would mean there are no physical collisions.
Is that what you want? Then go with OnTriggerEnter

If you want them to physically collide, and just not bounce, then OnCollisionEnter but destroy the bullet

It is entirely up to you

[gray mural]

For some reason I completely forgot that they should simply destroy them. In this case no trigger is needed, as there is no time for the bounce to happen

[gray mural]

So I don't think there are any other options you might require. Or do you, perhaps, want to not destroy, but simply stop your bullet and make it fall when the collision happens?

you are looking for something like this

[knotty sun]

presumeably you only checked the scene objects. You need to check any prefabs in your project that you instantiate as well

Okay thanks

[heady iris]

Clicking once on the message may highlight the source of the error in the hierarchy

[sly chasm]

links to a script

I go to the line [996]

[heady iris]

once, not twice

double clicking opens your code editor

(and you should do it while the game is running)

[sly chasm]

Ah, ok

i'll try that

[heady iris]

if that doesn't work, search for t:animator or t:mrider while the game is running

[sly chasm]

btw it highlights the player

[heady iris]

okay, so the player probably has an Animator or MRider component on it

[halcyon steppe]

Hi, I am currently writing a movement script and I am trying to implement movement on a slope. I got everythign working except for that I always get stuck on the transition from a flat piece of ground to a slope. How do I fix this?

If I sprint at the slope or jump on it it works fine but the transition while walking doesn't work.

In the screenshots you can see how I detect if I am on the ground and if I am on a slope as well as a Screenshot from inside the engine with my scene.

[spring creek]

Consider a spherecast instead of ray.
Everything should be the same except the method name
That will widen the area you query, letting you hit that leading edge of your player

Or do multiple rayasts

I will look into that, thank you very much

that doesn't really seem to address the main problem

I agree that you should use a spherecast rather than a raycast to determine if you contact the ground

but what do you mean by the transition while walking not working

[heady iris]

i presume OnSlope doesn't become true and they get stuck

[spring creek]

I assume the mean the common issue of when you start to go up the slope, the player lifts up, and you no longer register as grounded. (Or OnSlope in this case, as fen said)
But yes, that was an assumption

[halcyon steppe]

Fen is right, OnSlope doesnt change to true initially

Is there a way to display the sphereCast? Like Debug.DrawRay but for the sphere?

[spring creek]

Welll... there is Gizmos.DrawSphere

Or Debug.DrawLine and approximate what you need of the sphere

[halcyon steppe]

this is the situation at the bottom of the slope

[heady iris]

yes: the physics debugger!

[pastel patio]

Is it a good idea normally to use NativeArrays?

[heady iris]

I don't see any real reason to use them if I'm not passing them to Jobs

[pastel patio]

I'm using it in BatchRendererGroup

[heady iris]

window > analysis > physics debugger; you can turn on queries

note that only newer versions of unity have the query visualizer, iirc

[pastel patio]

More specifically, to keep a local copy of the instance data

I practically have to use the functionality to write a bigger type into a collection meant for a smaller type

[heady iris]

you'll have to show me what you're doing

[halcyon steppe]

I have it fortunately and boy is it helpful

Thank you so much

[spring creek]

Oh dang. That is awesome.

[pastel patio]

This is the place where it really clashes if I try to use a normal array

Span<PackedMatrix> objectToWorldMatrices = new Span<PackedMatrix>((byte*)localDataBuffer.GetUnsafePtr() + byteAddressObjectToWorld, maxInstances);
Span<PackedMatrix> worldToObjectMatrices = new Span<PackedMatrix>((byte*)localDataBuffer.GetUnsafePtr() + byteAddressWorldToObject, maxInstances);
Span<Color> colors = new Span<Color>((byte*)localDataBuffer.GetUnsafePtr() + byteAddressColors, maxInstances);

Uh, lemme just show the whole code

[heady iris]

oh, yes, you absolutely have to use a NativeArray when packing different kinds of data into a buffer

[pastel patio]

https://pastebin.com/JhzCemvf

This is my script

Uh, after I randomly swapped the native array for an array, just pretend localDataBuffer is still a NativeArray

[fallow quartz]

yeah the thing is ev en I print on screen i cant have a tracking history because the textmeshpro can only have 1 text

[halcyon steppe]

IT WORKS, you guys are legends! thank you again, Spherecast was the way to go and the physics debug is the best thing i have ever found!

[pastel patio]

Unity crashed with stack overflow errors tho

Although... To be fair pretty sure it's cus I forgot to dispose and ended up creating a memory leak... haha...

Still, would this NativeArray be eating up the stack?

[heady iris]

no, it's heap-allocated

a stack overflow is probably just infinite recursion

[pastel patio]

It wasn't recursion... Maybe it's when you start playmode they allocate a lot of stuff on the stack

[heady iris]

stack overflows are almost always caused by infinite recursion

show the stack trace

[pastel patio]

While the heap is kinda blown up thanks to the memory leak

[heady iris]

this is something in the UI breaking

[pastel patio]

Honestly... It was probably a side effect

Not the first time errors say this but it's that

The crashes stopped as soon I added localDataBuffer.Dispose() in OnDestroy

That's why I'm guessing that the heap was very much packed and then enter playmode made it crash

[gray mural]

• 1. What's the problem in testing it in the editor?
• 2. What's the problem in printing the full stack trace for the method on the screen?

[half saddle]

Does a visual effect clean up itself when all particles lifetime has passed or do I need to clean it up myself?

[fallow quartz]

you mean by adding a text mesh pro?

[gray mural]

What are you referring to?

[fallow quartz]

to print in the build

[gray mural]

I see, I'm sorry, I meant "in the editor"

[fallow quartz]

in the editor i cant test the resolutions bug cause it doesnt affect

in the editor theres no resolutions

[gray mural]

It still won't give you an error when trying to assign it

[pastel patio]

If you're talking about partical systems, there's a setting for that

If "CleanUp" means destroy

You can also set it to Callback, never used it but I think that it should allow you to make something execute when all particles expire

[fallow quartz]

i know but whats the point on doing that if i cant try if it works?

[gray mural]

You'll still be able to see the PlayerPrefs' values. It's just that the resolution set won't be visible

[fallow quartz]

i have a plugin to check in real time the player pref values

[gray mural]

So what's the problem then?

[fallow quartz]

resolution changing randomly to max or 640x480 for no reason when switching scenes, and is not even consitent

is just random

[half saddle]

VFX graph particles, not the particle system

I want to make sure compute shaders aren't still running in the background after all the particles have disappeared

[pastel patio]

Seems kinda absurd if they still do, it's a tool meant to be highly performant. Although I can't be sure about this one

Uh, although, in my case at least it ain't uncommon to still keep the memory to avoid re-allocating everytime

But that things are still running is another story

[half saddle]

I noticed in the scene if I play the visual effect without reinitializing it some attributes of the particles existed as if they had been going along this whole time, but that might just be a matter of the system knowing when they original were spawned and lerping the values from there, not updating while they had disappeared

[haughty ember]

I'm working on a game that involves both the player controlling a car as well as AI cars. I got a somewhat decent physics system working on my player car controller, but I know I'd like to make changes to the car physics in the future. AI cars should use the same physics. So naturally, I'd like the physics to be split into its own script rather than having a lot of duplicated code between the player controller and AI controller scripts. I'm struggling with 2 possible approaches. The first is making a base class "CarController" that the PlayerCarController and AICarController classes can inherit from. The other approach is to just make a separate CarPhysics script that can be called by the player car controller and AI car controller (for example, they could call "ApplyAcceleration", which would be movement input from the player and whatever input the AI decides for the AI). I tried the inheritance approach but it got kind of weird when considering the 2 separate inputs, does the CarPhysics separate script sound like it could possibly be better?

[pastel patio]

if you know all the things you would need to interact with and how, a separate script is cleaner imo

[somber nacelle]

separate components, where the input from the player and the input from the AI can be added along side the component that actually applies the input

[pastel patio]

Just wanna mention that a separate script can also cause you a bunch of hassle, if the two was meant to be more complexly coupled or stuff

I've had this struggle with my Health before- IHealth interface or Health component?

[haughty ember]

So you think the car physics separate script is cleaner then? For more context, yeah the current base car controller script is just applying a lot of forces (such as suspension, natural deceleration) each fixed update. The only 3 things it really needs input from an outside entity (player or AI) is acceleration, turning, and manual deceleration. So I'd imagine I can just call these from the controllers like "ApplyAcceleration, ApplyTurning, etc"

[pastel patio]

Yeah, if those are the only things you'd be good keeping them separate

I forgot what the deal was but it got pretty annoying when the health was a separate component from the creatures, so... Sometimes separate components ain't really optimal

[haughty ember]

Ok, thanks for the help that does seem better, was mostly finding inheritance examples online so just wasn't sure. I guess it does depend on the situation, I usually use health as a separate component but I also haven't made anything all that complicated yet to be fair

[pastel patio]

Inheritance gives a hell of a lot of control imo, drawback is how messy the inspector can become and if you don't watch out how messy the script can become too

[vagrant moon]

its always case by case, I usually go with separate script for reading inputs, and common scripts that could "handle" that input. than AI can have its scripts to provide its own input

[haughty ember]

Yeah I think inheritance would work here if there weren't so many implemented physics functions in the parent class. But there's just so much going on in the base script that the child classes never override that it seems like it should just be its own script

[pastel patio]

Yeah, good luck Fossil

Imma go back to my dungeon

[gray mural]

I won't be able to answer this without seeing your code. You should be able to solve this by printing the variables?

[fallow quartz]

cant send you the code right now, my partner is trying to figure it out and he has the script. Btw meanwhile, do you know how to work with tiles without getting lag? If i try to paint in the scene i have an insane amount of lag but if i use prefab i get this import load everytime i paint something

[gray mural]

No, no idea

Haven't used the tiles much

[neon harbor]

hello, im having an issue with accessing animation rigging components through scripts

i have the package installed in my editor

[somber nacelle]

try regenerating project files and restart visual studio

[neon harbor]

nope

doesnt work

[somber nacelle]

are you using asmdefs in your project

[neon harbor]

yep

oh

damn

you are right

it works now, thanks

[valid solar]

Okay so im super confused, if I can have a default virtual function in an interface, add it to a class, but not call the default implementation, what else would they be used for?

[vagrant moon]

you can cast your object to this interface type and call it than

[void void]

Hi, I'm currently trying to wrap my head around DOTS & ECS.
I'm prototyping a tower defense game so I've got lots of entities that will share the same data (waypoints along a path from their spawn point all the way to the "exit"). I've tried making use of ISharedComponentData to store the waypoint positions (as a list of float3) but I couldn't manage (having a float3[] inside a ISharedComponentData didn't sit right for some reasons). Many paths can exist so all entities might not follow the same path.
So I've just encountered BlobAsset and they seem to be one of the right tools to use in this case but I'm wondering about how to actually use them, should I:

• Store a BlobAssetReference (in a ISharedComponentData) that's created at bake time and Unity will figure that a lot of other entities share the same content hence use the same pointer thanks to some BlobAssetStore magic ?
• Store a BlobAssetReference (in a ISharedComponentData ) from a map of BlobAssetReference that's created at GameObjectConversion time ?
• Do something else that's more idiomatic of BlobAsset and DOTS ?

[rigid island]

#1062393052863414313

[void void]

Noted, thanks

[valid solar]

Thank you, feels ind of weird to do it this way.

[somber nacelle]

don't treat interfaces and default interface methods as inheritance and it won't feel weird to do that at all

[valid solar]

I mean why let me do it then real talk

[spring creek]

You can do a lot of terrible ideas

It is called flexibility

[fallow quartz]

this is the code:
https://hastebin.com/share/olupagaxop.csharp

only problem is when I close the game windowed

[somber nacelle]

just because you can treat it like that, doesn't mean you should. interfaces are not a substitute for multiple inheritance and should not be treated as such. interfaces are to provide a common interface to interacting with different objects

[fallow quartz]

Then, after opening again I only get 3 resolutions and without the HZ

[valid solar]

Okay let me propose a question then, If i want to have multiple objects to be buyable, but they can be different objects, and some require different implementations of the same method, whats the best way to implement them.

[somber nacelle]

there is no "best way", and what you've described can be achieved in a number of ways, none of which require you to try and use interfaces as a sort of multiple inheritance situation

[astral oriole]

For some reason this code doesn't return anything when on my mobile device, is there something I may be missing?

[heady iris]

are you sure it's being given valid data on your phone at all?

[astral oriole]

yeah the correct data gets passed

but nothing comes out for some reason

works perfectly fine on desktop though :/

[silent tapir]

Should I use scriptable objects or whats the best way for a modular gun system? with fireRate, damage, rounds, other characteristics, etc.

[heady iris]

scriptable objects are useful for storing data as an asset

useful for storing parts of a weapon, perhaps

but the actual definition of the weapon can be a plain old C# object

[fallow quartz]

Is there any way too do something in an audio so it sounds like if it was far far away?

or behind a door

[heady iris]

there are audio filter components you can add to the same object as an audio source

a reverb filter plus a low-pass filter can give you a "muffled" effect

[rigid island]

I make my SO hold my stats in a POCO for the base stats, this way i only copy the poco to add modifiers and stats to

[silent tapir]

whats SO and POCO

[somber nacelle]

ScriptableObject and Plain Old C# Object

[fallow quartz]

I got this but still not feeling completely nice

[quick token]

does anyone know why i cant change an objects parent and position/rotation on the same frame?

AnchorPoint.transform.up = plcCon.ConnectionPoint[1].TransformDirection(Vector3.up);
placing.transform.SetParent(AnchorPoint.transform);
AnchorPoint.transform.up = -conPoint.up;

this code works but it it doesnt rotate the child and parent. it only rotates the parent

same code but without the messy variable names:

A.up = B.TransformDirection(Vector3.up)
C.SetParent(A)
A.transform.up = -D.up

A's position/rotation is correct but C's is not

basically im just rotating it, adding a child and rotating it again

for some reason unity doesn't seem to rotate the child

nvm, I'm dumb

i forgot to delete a line i added like 3 days ago ._.

[heady iris]

You'll want to use a cusatom reverb preset and mess with the dry level

The dry level is how much of the un-processed audio is kept (measured in decibels, so 0 is 100% strength)

[silent tapir]

huh? wdym

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

public class Weapon : ScriptableObject
{
    
}

[heady iris]

a "POCO" being a "plain old C# object"

a class that isn't inheriting from MonoBehaviour, ScriptableObject, etc.

You store the weapon definition as a Weapon. If you want to make a weapon preset, you make a WeaponPreset scriptable object that stores a Weapon

[rigid island]

class WeaponData : ScriptableObject
class WeponStats etc.

[silent tapir]

all in one script?

[rigid island]

no just showing for brevity

[heady iris]

You can only define one MonoBehaviour or ScriptableObject per script file.

You can wedge other classes in, if you want

[silent tapir]

this work?

using UnityEngine;

[CreateAssetMenu(fileName = "NewWeapon", menuName = "Weapon")]
public class Weapon : ScriptableObject
{
    public string weaponName;
    public int maxAmmo;
    public float fireRate;
    public float reloadTime;
    public GameObject weaponPrefab;
    public AudioClip fireSound;
    public AudioClip reloadSound;
}```

[rigid island]

I would do it a bit different

[silent tapir]

How so?

[rigid island]

Seperation of concerns

public class Weapon : MonoBehaviour
{
    public WeaponData WeaponData;
}
public class WeaponData : ScriptableObject
{
    public WeaponStats Stats;

    //other sutff like
   //AudioClip FireSoundl;
    //etc

}
public struct WeaponStats
{
    public float FireRate;
    public int MaxAmmo;
    //etc.
}

[heady iris]

indeed

Weapon is the actual component in the game world

[silent tapir]

So, why would I separate the WeaponStats in two diferent categories?

[silent tapir]

makes senese

[heady iris]

I'd rearrange it a bit

[rigid island]

well no reason to mix Stats data , with AudioClips or other assets

just personal preference

[silent tapir]

using UnityEngine;

public class Weapon : MonoBehaviour
{
    public WeaponData WeaponData;
}

[CreateAssetMenu(fileName = "NewWeapon", menuName = "Weapon")]
public class WeaponData : ScriptableObject
{
    public string weaponName;
    public int maxAmmo;
    public float fireRate;
    public float reloadTime;
    public GameObject weaponPrefab;
    public AudioClip fireSound;
    public AudioClip reloadSound;
}```

[heady iris]

so that WeaponData is also a plain old C# object; you can create SOs to hold a WeaponData as a "preset", as well as other types to hold stuff like muzzle flash definitions

[rigid island]

easier to copy the whole WeaponStats to modify it on the instance

[heady iris]

public class MuzzleFlash : ScriptableObject {
  public ParticleSystem particleSystemPrefab;
}

(you might add more fields later)

[silent tapir]

hm interestin

[silent tapir]

so does this work?

[rigid island]

yeah it works fine

[heady iris]

not if you put both in the same file

but otherwise yes

[silent tapir]

yeah ik

[heady iris]

However, if you want to be able to modify the weapon as you play the game, you probably don't want to shove all of the stats into a scriptable object

if two places use the same scriptable object (e.g. you have two of the same weapon type), modifying one will wind up modifying the other

use ScriptableObjects to hold definitions of things, like a kind of muzzle flash

[dense surge]

Where’s the channel to get help

[rigid island]

indeed , thats why I made poco on it to copy basestats and then modify

[rigid island]

id:browse pick one

[silent tapir]

How could I go about doing this.

I don't use pocos much

[heady iris]

you just make a class

mark it [System.Serializable] so you can serialize it in the inspector

[dense surge]

Huh

[silent tapir]

should I just slap the weapon.cs on the gunHolder or the gun?

[heady iris]

i don't know what a "gun holder" is here

[rigid island]

do note I usually make the weaponStats struct so it can just be copied values

[heady iris]

Weapon represents the actual weapon in your game world.

[silent tapir]

ik, but I have a parent to the gun model called gun holder

but I can just put it on the gun GameObject

[rigid island]

well the model shouldn't be your root object anyway

[silent tapir]

why not

[rigid island]

because graphics should always be separated from logic

[silent tapir]

ok, it ain't just asking

[rigid island]

looks fine

[silent tapir]

yeah

now how should I access the weaponData properties properly in the weapon.cs script

[rigid island]

so yeah Lets say I made weaponstats a struct,
I can just do ```cs

public class Weapon : MonoBehaviour
{
public WeaponData WeaponData;
public WeaponStats currentStats;
private void OnEnable()
{
if (WeaponData != null)
{
currentStats = WeaponData.Stats;
}
}
public void IncreaseFireRate(float amount)
{
currentStats.FireRate += amount;
}
}```
on the weapon for example

[silent tapir]

wheres the struct

[rigid island]

on the SO

public struct WeaponStats
{
    public float FireRate;
    public int MaxAmmo;
    //etc.
}```

[silent tapir]

oh shit I see

mb lol

whats the weaponData do then

[rigid island]

but yeah you would make them System.Serialiazable so they can be modified in inspector

[silent tapir]

oh its the base model to be copied

i see okay

[rigid island]

hold stats, audioclip sounds, model, etc

[silent tapir]

where is the class WeaponStats supposed to be initialized?

[rigid island]

it makes it so you can just swap an SO and your weapon is now different

[silent tapir]

in WeaponData?

[rigid island]

you do it in the inspector

[silent tapir]

no i mean where is it defined

[rigid island]

put it in a different file, doesn't matter

like I said this is fine, is just more annoyance to copy individual fields than a whole struct

if you plan on modifying those stats that is

if not then yeah don't worry about it

[lusty gull]

hello everyone, i need some help building my unity project. I need to make a build with il2cpp for windows. Right now i only have access to a linux machine, and i can't find a way to build for windows using il2cpp backend. I already tried using a virtual machine but the build gets stuck. Does anybody know a way to build for windows from another platform?

[rigid island]

Unity Cloud offers a service like that
https://build.cloud.unity3d.com/landing/

[silent tapir]

using UnityEngine;

[CreateAssetMenu(fileName = "NewWeapon", menuName = "Weapon")]
public class WeaponData : ScriptableObject
{
    public string weaponName;
    public int maxAmmo;
    public float fireRate;
    public float reloadTime;
    public GameObject weaponPrefab;
    public AudioClip fireSound;
    public AudioClip reloadSound;
}

public struct WeaponStats
{
    public WeaponData weaponData;
}``` this look correct?

or do I have it backwards

I think I do

idek

[rigid island]

what did you do..

look at my examples from before lol

[silent tapir]

well its confusing because you have the same variables in each one

[lusty gull]

try putting maxAmmo fireRate and reloadTime in WeaponStats, then declare WeaponStats inside WeaponData

[silent tapir]

or they are both storing variables that are relevant to just the gun

[rigid island]

[CreateAssetMenu(fileName = "NewWeapon", menuName = "Weapon")]
public class WeaponData : ScriptableObject
{
 
    public WeaponStats WeaponStats;
    public GameObject weaponPrefab;
    public AudioClip fireSound;
    public AudioClip reloadSound;
}
[Serializable]
public struct WeaponStats
{
    public string weaponName;
    public int maxAmmo;
    public float fireRate;
    public float reloadTime;
}```

[silent tapir]

using UnityEngine;

[CreateAssetMenu(fileName = "NewWeapon", menuName = "Weapon")]
public class WeaponData : ScriptableObject
{
    public WeaponStats weaponStats;
}

public struct WeaponStats
{
    public string weaponName;
    public int maxAmmo;
    public float fireRate;
    public float reloadTime;
    public GameObject weaponPrefab;
    public AudioClip fireSound;
    public AudioClip reloadSound;
}```

[silent tapir]

oh

wait whats the point of separating them

[rigid island]

ideally you only want value types inside struct

[silent tapir]

they are both useful to the gun

[rigid island]

I would only seperate if you plan on modifying the stats

[silent tapir]

oh bc the fireSound doesn't change?

[somber nacelle]

the prefab and sounds are not "stats"

[silent tapir]

still going to modify them tho

[somber nacelle]

they can be considered part of the data for the weapon, but they are not the weapon's statistics

[silent tapir]

so idk what the point of separating them are

[lusty gull]

also is better to not put references inside structs because they get passed by value

[fallow quartz]

okay thx ❤️

[silent tapir]

but im modifying them both

[silent tapir]

so how does this not work?

[rigid island]

reloadSound sounds as stats makes no sense to me

stats are numbers

[silent tapir]

What if I am changing the gunModel because I am adding a silencer to it. but only for one person.

[rigid island]

thats not something you would ever change on a SO

if you change it on a SO it will change it for everyone who has that same SO

[silent tapir]

what if I am changing the sound for a silencer? @rigid island

[rigid island]

look for example, If i want to change fireRate Im only doing it on this weapon.

Im not changing it for everyone that has this weapon

[silent tapir]

exactly whats wrong with changing the audio due to a silencer then>?

[lusty gull]

it all depends on whether you want the change to persist on disk or not. if it has to persist in the same scene only, make a routine that changes the model on the MonoBehavior

[rigid island]

if you change it on the SO it will change it for everyone

[silent tapir]

not if you do it on the copy version tho

on the currentStats

[rigid island]

Reference types work differently

[lusty gull]

also, you can use Instantiate on scriptable objects to get a copy, and then reassign the new one

[rigid island]

thats why i dont mix them in struct as much

[silent tapir]

ah okay

[rigid island]

they cannot be copied, only bring the original with you

[heady iris]

getting a bit lost in the weeds here

[silent tapir]

using System;
using UnityEngine;

[CreateAssetMenu(fileName = "NewWeapon", menuName = "Weapon")]
public class WeaponData : ScriptableObject
{
 
    public WeaponStats WeaponStats;
    public GameObject weaponPrefab;
    public AudioClip fireSound;
    public AudioClip reloadSound;
}
[Serializable]
public struct WeaponStats
{
    public string weaponName;
    public int maxAmmo;
    public float fireRate;
    public float reloadTime;
}``` there

[rigid island]

yes tbh to me this makes more sense

[heady iris]

if you want to allow upgardes to have effects on the weapon's visuals and sounds, you need to make it so that each "modification" to a weapon gets a chance to modify the weapon's vfx/sfx

for example, each modification could be allowed to attach extra models to the weapon

[silent tapir]

ah alr

[heady iris]

a "silencer" modification would add models to each barrel on the weapon

[silent tapir]

can I just go ahead and put whatever for these?

[rigid island]

pretty much

[heady iris]

and, when you fire it, the silencer would override the audio clip that gets used

it's a non-trivial problem

I did something like this during a game jam once

[rigid island]

WeaponName might have to stay in WeaponData

since you're not gonna be changing that

[silent tapir]

could

Upgrade it to Legendary Glock

for e.g.

[heady iris]

modifiers could also prepend or append text, yes

[latent latch]

That would be another field

[heady iris]

"silenced armor-piercing glockinator"

[silent tapir]

lol

[latent latch]

make yourself defaults and only ever read from them

[rigid island]

yes, you would not modify anything on this one, only a copy of them

[silent tapir]

gothcu

so I could change these ones tho

[rigid island]

those can be mutable no problem

as they are a copy of the original

[silent tapir]

bruh wtf

[silent tapir]

alr

[rigid island]

yes that REGEX preventing spam

[silent tapir]

ah okay

[fallow quartz]

btw @heady iris do you know why in this code:
https://hastebin.com/share/olupagaxop.csharp

when i restart the game while being on windowed resolution changes for some reason

[dense surge]

Can you download unity on a school chromebook or chromeOS just wondering

[spring creek]

I do not believe so

I mean, you could probably download the file. But not install it

[dusk apex]

A concern might be the size/capacity of your hard drive - some chrome books have limited eMMC memory.

[full canopy]

I have several scripts that work in tandem to make a very good VR bolt-action handler. I updated some things and it no longer works, for some unseen reason

They are also executed in a specific order:
(1) GoTo: tracks one local rotation axis and any/all of the position axis to another object. In this case, rotates toward my hand along only the local z axis, and also moves only along the local z axis toward my hand.
(2) TransformLimiter: flag enum to allow limiting of x/y/z rotation and x/y/z position. clamps the local rotation/position for each enabled axis to a low & high number in the inspector
(3) BoltAction: dumbed down, changes the relevant (in this case onl z rot and z pos) low and high clamp ranges when the bolt is in a certain area.

when TransformLimiter is disabled, GoTo accurately follows my hand along the z rotational axis. no issues with tracking and there is no unaccounted for offset. Its local rotation in the inspector also falls within the range limited by TransformLimiter
when TransformLimiter is enabled, the object snaps to its high range value and no longer rotates at all.
the BoltAction script seems to have no effect at all.

below is relevant portions of code

GoTo

//rotation
. . . . .
if (transformConditions.HasFlag(toggles.RotZ))
{
    newAngle.z = Mathf.Rad2Deg * Mathf.Atan2(relative.x, relative.y) * -1;
    from.localEulerAngles = new Vector3(from.localEulerAngles.x, from.localEulerAngles.y, newAngle.z);
}```

TransformLimiter

//rot
. . . . .

limitedTransform.localEulerAngles = new Vector3(limitedTransform.localEulerAngles.x, limitedTransform.localEulerAngles.y, Mathf.Clamp(limitedTransform.localEulerAngles.z, zRotationLimit.x, zRotationLimit.y));
}```

oh btw originalReference has the exact same starting transform as the object with these scripts

I'm trying to change the color of my played particle system with a script to a green color. But when it plays, it's gray. If I change my particle system's color using the inspector, 51, 204, and 40 is the correct colors for green. What am I doing wrong?

    public void PlayParticle()
    {
        ParticleSystem currentParticle = Instantiate(gas, foo.transform);
        var main = currentParticle.main;
        Color color = new(51, 204, 40);
        main.startColor = color;
        currentParticle.Play();
    }

[dusk apex]

Color expect values between 0f and 1f https://docs.unity3d.com/ScriptReference/Color.html

[waxen blade]

Oh.. that's unexpected.

I was trying to set it to the RGB values that go up to 255. Is there a different method I can use?

[dusk apex]

The Color32 constructor would take values between 0 and 255

Color color = new Color32(...)

https://docs.unity3d.com/ScriptReference/Color32-operator_Color32.html

[waxen blade]

Hmmm maybe I won't be able to use Color32.

[dusk apex]

Lookup what a min max gradient is

https://docs.unity3d.com/ScriptReference/ParticleSystem.MinMaxGradient.html

[waxen blade]

It's basically a color range right?

[dusk apex]

Look through the docs. It returns a Color but it's something more. There are properties at the bottom of the page that you might be interested in.

This contains two Gradients, and returns a Color based on ParticleSystem.MinMaxGradient.mode. Depending on the mode, this may return the value randomized.

[waxen blade]

I decided to go back to Color and divide by 255 to get the same number, but one that Unity accepts, and it works.

Color newColor = new Color(51f/255f, 204f/255f, 40f/255f);
main.startColor = newColor;

I have a lot to learn about particle systems though, and colors are clearly a staple of them, so I'll look through the article you sent.

[dusk apex]

Pretty sure you could implicitly acquire a Color from a Color32

[waxen blade]

Thanks for helping me get to the solution Dalphat.

Hey guys I need some help, I have a 2D rigged character with an animation. I want to create a character editor at runtime, where I can swap out the sprites for the head, torso, legs etc. But when I change the sprite of the head it is no longer attached to the rig and the character becomes unusable. I do have 'Auto Rebind' checked as well. Is thre something specific that I am missing?

[leaden ice]

But when I change the sprite of the head it is no longer attached to the rig and the character becomes unusable
Why?

Are you using skeletal animation?

[dull cedar]

Yes

[leaden ice]

https://docs.unity3d.com/Packages/com.unity.2d.animation@10.1/manual/SpriteSwapLanding.html?q=sprite swap

https://docs.unity3d.com/Packages/com.unity.2d.animation@10.1/manual/SpriteSwapIntro.html#skeletal-animation-limitations

[dull cedar]

Thank you, this does help. But it requires me to copy the rig and have the other skin also be rigged. At runtime I want to download sprites and then swap them out in the skeletal character.

[leaden ice]

Download from where?

[dull cedar]

Cloud storage

[leaden ice]

But who is publishing the things to be downloaded?

You? Or users?

[dull cedar]

The users, the user could potentially upload their own sprites

[leaden ice]

If it's users, this doesn't seem possible because how do you expect the sprites to become rigged (weight painted etc)

Maybe if you have them author the sprites with Unity, rig them, and upload them as AssetBundles?

If it's just like, an image file, that doesn't contain enough info to do skeletal animation

[dull cedar]

I would have to do this at Run time I can't ask the users to get unity to edit and upload

[leaden ice]

Not sure where you expect to get the animation rigging data from then

The alternative here is to use spritesheets/multiple sprites without any deformation

[dull cedar]

I'm actually doing that right now. I wanted to see if there was a rigged character solution

[leaden ice]

Well someone has to rig it.
Either build a tool that lets your users do the rigging
Or build something with AI???

[dull cedar]

Is there a way to generate the geometry at runtime?

[leaden ice]

Maybe?

You'd have to dig through https://docs.unity3d.com/Packages/com.unity.2d.animation@10.1/api/UnityEngine.U2D.Animation.html

but again

I don't see how you could take an arbitrary user-provided image and know how to generate the geometry procedurally

The only feasible solution I can think of is training an AI to do it.

[dull cedar]

ok thank you I might have to try something else

[full canopy]

solved: apparently, it doesn't like negative numbers as the low and high values. adding 360 to both inputs made it work flawlessly

[tulip frigate]

I've some problem for a while now, maybe someone here can solve it:

I'm working on a simple input script using Input.GetAxis for horizontal and vertical movement in a 3D game. The player object moves with a Rigidbody based on this input.

Before actually moving the player object (using rb.velocity = ...), I'm saving the input vector to a list so I can "replay" the input later. This works fine: I can move normally and replay the input to replicate the same player movement.

The problem arises when the player object physically interacts with other Rigidbody objects in the scene (e.g., a new Cube object with a Rigidbody). Here's what happens:

When I push the cube around for a few seconds (like a soccer player dribbling a ball) and then replay the input, the playback behaves differently. The replayed player object ends up slightly off from the original position, losing the cube it was pushing, and finishes at a different location than expected.

Important to note that the playback itself does actually get the same result every time; I mean, I can replay it over and over and the results will be 100% consistent and identical, even with physics interaction.

Any ideas?

[full canopy]

it might just be unavoidable floating point error if the playback you made is, at the base level, doing the exact same thing you do when you use input. weird issue

it could also be the execution order being slightly off now that i think about it

some things execute instantly and some on fixed update

so depending on your implementation it might be fractions of a frame off, but enough to cause a difference

ive had that issue come up so so many times making my vr game, things happen in between frames but it still affects the physics output

[latent latch]

replay by exact coordinates, not by functionality of the physics system

could maybe record yourself a timeline and replay it as an animation clip

[full canopy]

its possible using physics is necessary for scarlet

there might be ways you can fake it though if you want the effects of physics on things

[latent latch]

just lerp it all, it'll probably be fine

[full canopy]

im saying the rigidbody might be necessary

like to push stuff around, bounce, slide, whatever

[tulip frigate]

Yes physics are crucial for my purpose, but how is the physics interactions are always the same when replaying the same playback over and over?

[full canopy]

unity's physics engine is pretty good, so most of the time if you have the exact same starting conditions, youll get close to the exact same ending conditions

[tulip frigate]

But If order of execution might be the problem, why doesnt it affects this case?

[full canopy]

well because the order would always be the same

[latent latch]

I'd try messing with the detection modes maybe

could be that messing with the second rigidbody then does a sweep for other rigidbodies

[full canopy]

quick question, are you recording the input on update or fixed update?

[tulip frigate]

Input recording on update and movement itself (changing the rigidbody) happens on fixedupadate

[full canopy]

ok try adding to the input recording list on fixed update instead

that way it is recorded at the same rate its later re-played

[tulip frigate]

Yea thats what happen atm

[full canopy]

unfortunately i told myself id go to bed almost an hour ago and here i am still so im heading out, hope you find the help u need

[tulip frigate]

Lol np , good night

[tulip frigate]

Yep i tried all the modes, no success

[latent latch]

My assumption is that moving the rigidbody probably takes in consideration of others once you move it. Perhaps something to do with interpolation settings and whatnot.

But I'm just kinda throwing out guesses here

I just know that rigidbody vs rigidbody calcs require a bit more setup, and it's not as deterministic as saying bouncing a ball across a static environment.

[tulip frigate]

Hm, but i dont think that it still explains why replaying the same record over and over is still deterministic

[latent latch]

True. I'm surprised you do get accurate results by replaying it with that single rigidbody.

[tulip frigate]

After all, the different only lays between whether the player object get the input directly from the input system or from the list

[obtuse surge]

hi guys, so basically im using Animation to move car, does anyone knows why when I play on editor suddenly the object attached got un-attached?

void Start()
{
    animator = GetComponent<Animator>();
}

public void Something()
{
    AnimatorStateInfo stateInfo = animator.GetCurrentAnimatorStateInfo(0);
    if (stateInfo.normalizedTime >= 1f)
    {
        gameplayTwo.SetActive(false);
        checkpointTele.SetActive(true);
    }
}```

[brave musk]

How accurate is timeline with playing audio clips? I have the playable director on DSP time and have been using the timeline to sequence a rhythm games interactions, but the timing feels slightly inconsistent across plays

I'm not sure if there's an issue with the playable director itself, or if it's something with my own code

[gusty aurora]

Post a clip

[tulip frigate]

I will get home later and I will post hete

[fallow quartz]

Is there anyway to check where a script is being used in unity?

[thin aurora]

Nothing in this code has anything to do with unattaching anything, please share a video and more context

[obtuse surge]

okay let me record it

[soft shard]

In Visual Studio, you should be able to see above the class name which assets are referencing that script, I believe you can also right-click the script in Unity and "Select Dependencies"

[thin aurora]

Their question was wether it was used in Unity. I assume this is related to if the script is being used as a component of a gameobject and not referenced by other scripts

[thin aurora]

You should be able to search for a component using the search feature, though I forgot the specific term to search for

Otherwise put a log in its awake method like this:

Debug.Log("Awake", gameObject);

You can then press it and navigate to the component

There are more ways but these are the easier ones from the top of my head

[fallow quartz]

And is there anyway to check if a method is being used in unity? Like by a keyframe event or in the inspector in a button with onClick

or something like that

[soft shard]

Ah, I thought the visual studio reference would tell you if its referenced on for example, a prefab, its likely a component of that prefab, though I guess it might not tell you which scriptable objects in your project use that script or more fine details

[thin aurora]

It doesn't do that, no

Maybe there are extensions like that though

[fallow quartz]

When using SHIFT + F12 on visual studio it doesnt detect StateBehaviourScripts?

[slender nymph]

do unity limit FPS on UI for android build, if yes how can i change the limit

[wooden pawn]

Hello. I am new to using the ScriptableObject behavior for my scripts, but I thought I'd try again by making a set of collectible objects in my game that would go to an inventory system. Right now it's in the early stages, but I ran into an error I'm not sure how to fix:

https://gdl.space/oqafuzamox.cs

When the object is collected, for now I just want it to say in the debug log what item was collected. However, it gives this error:
ArgumentException: GetComponent requires that the requested component 'Weapons' derives from MonoBehaviour or Component or is an interface.
UnityEngine.Component.GetComponent[T] () (at <55fbbbd17b724c15b6abe8c1a3e3289c>:0)
Player.CheckTile (UnityEngine.Vector3 target, UnityEngine.Vector3 raycastStart) (at Assets/Scripts/Player.cs:116)
Player.Update () (at Assets/Scripts/Player.cs:27)

I think I understand what its saying, that the Weapons SO component attached to the game object isnt derived from monobehavior or component, but I have no idea how to change the code or SO so that it works

[leaden ice]

ScriptableObjects are not components, and cannot be fetched with GetComponent

In your screenshot the component is called "Collectible" @wooden pawn

[wooden pawn]

Got it

That makes a lot of sense

Too many things I'm learning at once

My brain starts to combine everything

[wooden pawn]

public string collectedItemName { get; private set; }
collectedItem = hit.collider.GetComponent<Collectible>().Weapon.WeaponName;

is this the best way to do it?

then I can use Player.collectedItem in the debug log message

[wooden pawn]

public void GetItem()
{
Player p = GameObject.FindWithTag("Player").GetComponent<Player>();
Debug.Log("Attempted to grab item: " + p.collectedItemName + "\n" + "With attached value: " + p.collectedItemValue);

weapons.Add(p.collectedItemName, p.collectedItemValue);

}

Trying to add the key and value to a dictionary called "weapons", but it keeps giving a null reference exception.
The debug log works, saying the items name and value, but it gives an error on the dictionary add line

[mellow sigil]

weapons is null

[wooden pawn]

public Dictionary<string, float> weaponsDict;
this is at the top of the script(i changed the name to weaponsDict to be more precise)

[mellow sigil]

Yes, that's null. You haven't put anything in the variable

[wooden pawn]

Doesn't the .Add function do that?

i must have read the docs wrong

[mellow sigil]

No, that tries to add items into the dictionary but the dictionary itself doesn't exist

public Dictionary<string, float> weaponsDict = new();

[wooden pawn]

Oh right I forgot I had to do that

Does "new()" work with other things youre initializing, like Vector3s and stuff

I've always written it out as = new Dictionary<> etc

[mellow sigil]

You can omit the type in the latest Unity versions, yes

[wooden pawn]

Thank you

[harsh rapids]

Hi everyone, i was updating my project on two different devices, and my player moves at different speeds corresponding to devices, while the values are the same. got any ideas as to why?

would it be related to screen resolution?
