Did you assign sword in inspector?

[sacred egret]

do isend the log

yes

[rocky canyon]

do u get a debug.log???

in teh console?

[sacred egret]

no

[rocky canyon]

cuz if not ur question should be "Why doesn't my if() conditional even run

did you set up the "e" button in ur input settings?

b/c if not it wont work..

KeyCode.E would be an alternative

that would work regardless b/c its a generic Input

[sacred egret]

ill try it thx

[rocky canyon]

      if (Input.GetKey(KeyCode.E))
        {
            Debug.Log("e pressed");
            sword.SetActive(true);
        }```

when you just use something like "e" it would need to be set up in the Input's so Unity knows what "e" even is

KeyCodes are easy to use when prototyping

[sacred egret]

it worked thx

[amber spruce]

how do i make a dash that has the player like flicker in and out

[rocky canyon]

probably a shader or visual effect of some sort

u could just enable and disable the Renderer component..

[amber spruce]

im also struggaling with the actual dash part to

[timber tide]

could make that in the animator

[rocky canyon]

to fake it

[ornate patrol]

hello! i just started learning unity and ran into this problem, where only the idle animation is visible and others are not (only the outline in preview is visible). how can i turn them on?

[timber tide]

do a animation clip that changes the alpha of your character and move it some units forward

[rocky canyon]

make sure the graphic is IN FRONT of the background

ur Z position is 0.. probably the same as ur background

u should move it a little forward towards the camera..

so it stays on top

[amber spruce]

well my 2 problems is 1 how do i figure out what direction to move them in and i have tried this to move them and it doesnt work

rb.AddForce(new Vector2(dashDirection.x * dashSpeed, 0f), ForceMode2D.Impulse);

dashDirection is just equal to transform.right

just to test it

[timber tide]

well, you can do it by transform position if you use the animator

but you may want to also do an additional raycast check so you dont teleport into walls

[rocky canyon]

u can animate the graphics only.. then still use ur physics to move it

[amber spruce]

well my physics isnt working

[rocky canyon]

graphics would control the flicker.. the movement code, the movement

ahh, gotcha

[amber spruce]

weird thing is if i switch it around to apply the force to the y axis the player moves up properly just doesnt work on the x axis

[rocky canyon]

well.. if u move it upwards u lose contact with the ground..

if u moving laterally u would remain in contact with the ground..

could the ground and the drag/friction/ stuff have anything to do with that?

try changing values... give it a BIG force and see what happens

[amber spruce]

i did i gave it like 1000

what is the default layermask that doesnt filter anything?```cs

[rotund hull]

https://gdl.space/ecasemivap.cs i am trying to print the int the is Amount in this code but it logs "Script or property 'Amount' not found" and i know that it is not finding the Amount int, can someone help

[rocky canyon]

Default is the "Default" Layer

[slender nymph]

https://docs.unity3d.com/ScriptReference/Physics2D.DefaultRaycastLayers.html

[queen adder]

ohh so -5

[soft steppe]

check if player is grounded without using raycasts and ground layers (2d)

[gilded ibex]

when smoothly changing things in unity, is something like DOTween the standard, or is there something I'm missing?

[timber tide]

very interesting code, but you should be specifically targeting the type of your script and not mono

[rocky canyon]

ya that code is confusing..

[rotund hull]

but i am trying to make it so that it can get any script and i dont have to change anything

trying to make an item pickup

[slender nymph]

why would you need to get any component?

use an interface if you want a specific group of separate components

[rotund hull]

Amount is a int in another scripts

[timber tide]

target by interface or abstraction class

[rotund hull]

what is interface

[timber tide]

good time to learn them

[rocky canyon]

in Unity you can Lerp, and Slerp, etc
DoTween is basically a library that does the same type of thing but with many more features..

[rotund hull]

alrighty

thanks

[gilded ibex]

so do you use DOTween (or something similar)? or are you writing your own coroutine every time you wanna animate something

[true pasture]

would it be okay to just continually set the text value in update referencing my stats. That way I don't have to update this manually each time a stat changes?

[rocky canyon]

yup, u can use interfaces. they're basically contracts.. meaning if you make an interface that has a Amount variable then all the scripts that use that interface MUST have an Amount variable. same for functions..

this way when you try to get something thru an interface you know that it MUST have the things ur searching for..

thus making it much easier to access stuff like that

[rocky canyon]

i use DoTween

[slender nymph]

i would personally recommend using an event and just invoking the event when a stat changes. then the objects can react and update the text themselves

[rocky canyon]

^ yea, the common consensus is the opposite of what u just said.

u want to try to update things like UI as little as possible..

[true pasture]

oh like check if the stats changed on a frame then update if true?

[rocky canyon]

if it doesn't change you shouldnt need / want to update it

[rocky canyon]

like if you attack something and it damages your stats. u can Tell the UI to update itself.. b/c u know u just got damaged..

[queen adder]

updating perframe is the lazy version, best to just cahnge it when some value change

[slender nymph]

no, use an event. that is a specific thing. you won't need to do anything in update if you just use an event

[rocky canyon]

isntead of checking every frame.. to see if it changed

[queen adder]

id use a prop instead of events though

simpler

actually that's quite the same

[rocky canyon]

    void DamagePlayer(int damageTaken)
    {
        // the player just got damaged..
        PlayerHealth.value -= damageTaken;

        // then the UI should Update
        MyUIManager.UpdateHealth(PlayerHealth.value);
    }```

just an example snip

[queen adder]

.UpdateAllStat()

[slender nymph]

also PrimeTween is the sexy new tweening library on the block. allocation free, allegedly better performance, and still fairly easy to use

[upbeat stirrup]

would a private serialized variable be named _myVariable or myVariable?

[rocky canyon]

up to you..

myVariable is what i use..

becaues my local variables use the underscore

[slender nymph]

either one. c# conventions state _ prefix for non-public members. whether it is serialized or not has nothing to do with the naming convention

[upbeat stirrup]

alr, just getting caught up in microsoft docs lol

[rocky canyon]

but consistency is the key

just stick to 1 convention and you'll be alright

[queen adder]

Me who is sticking to freestyle convention:

[rocky canyon]

lol..

[queen adder]

freestyle whooooh

[timber tide]

underline is one too many extra keys to press

[queen adder]

yea i only mostly use underscore as variableseparator

    public static IEnumerable<T> Circle_GetAllComponent<T>(Vector3 position, float Radius, int layermask = -5)
        => Physics2D.OverlapCircleAll(position, Radius, layermask)
        .Select(x => x.GetComponent<T>());```

[timber tide]

makes more sense in python since it's more concept than actually enforced

and javascript, but javascript is bad

[little oak]

how can i add a child of a prefab into a transform variable in a game object?

[amber spruce]

how do i get the direction to dash my player in

[little oak]

ping me if u can pls

[timber tide]

same way you move in a direction

[sacred egret]

how to refrence a variable from another script and do the scripts have to be attached to a same object

[slender nymph]

https://unity.huh.how/references

[sacred egret]

so like this?

[teal viper]

What's the value thing for?

[polar acorn]

Is NailController.EnemyLife a Type?

If not, then this should be a compile error and underlined in red

[sacred egret]

nope its supposed to be an integer

[slender nymph]

you may want to visit the beginner c# courses pinned in this channel to learn wtf you are doing

[polar acorn]

Then step 0 is to configure your !ide

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[polar acorn]

So stuff like this shows up as errors

[amber spruce]

how can i tell when the dash stops?? so i can enable the sprite renderer again

[polar acorn]

How long is a dash

[little oak]

i got it

transform.getchild(index).gameObject

[amber spruce]

idk i just do rb.AddForceX(100 * dashForce);

[sterile hull]

is coding usually for writing plugings?

[polar acorn]

Then I'd say the first step towards finding out when a dash is over is to decide what that even means

[polar acorn]

I have no idea what you mean by this question

[eternal needle]

This is less of a dash and more of just moving really fast temporarily. Your only option here would be impose your own time limit, or check the velocity (which will be inconsistent times)

[amber spruce]

what should i do to make it more of a dash

[eternal needle]

Hard to say, given I have no clue how your game is supposed to function. What's the use case, what do you need to know the end for?

[amber spruce]

im trying to make a cool dash effect and thought a cool effect would be have the person basically flicker in and out

[polar acorn]

That's really up to you. "Dash" isn't really a concrete thing you can just slap into whatever you're going to have to decide how it functions in your specific project

[amber spruce]

kinda like the effect given when goku uses instant transmission

[sterile hull]

like do you need to code to actually make something decent? or is it just to advance and cultivate the experience? like plugings

[polar acorn]

You will not be making anything with zero programming

[eternal needle]

This has no relation to what I asked, making it cool doesnt help me know what you need the end of the dash for. You probably want to just use a timer

[amber spruce]

i need to reenable the sprite renderer at the end of the dash

[sterile hull]

im used to making games in rpg maker with limited javascript knowledge to write some plugings i have no idea also-

[sterile hull]

not-nothing is not someting im aiming for, off to learn code thanks

[amber spruce]

how do i fix this so it moves the same distance but slower

[teal viper]

Apply less force for longer.

[amber spruce]

wont the decrese the distance though

[teal viper]

If you apply it for long enough, no.

[amber spruce]

so what just like have a coroutine apply the force multiple times?

[teal viper]

Are you applying it once currently?

[amber spruce]

yeah

[teal viper]

Preferably fixed update if you want it to be precise. But a coroutine might work as well.

[queen adder]

any experts in character movement know a good tutorial?

[frosty hound]

Experts presumably wouldn't be using tutorials. You should be asking the beginners. 😌

[queen adder]

any beginners have a tutorial for good 3rd person movement?

[teal viper]

As an "expert" I can say: google!😬

[stuck palm]

how can i fix this?>

[slender nymph]

https://docs.unity3d.com/ScriptReference/ParticleSystem-main.html

[stuck palm]

this is still causing the issue

[wintry quarry]

startRotationY is a struct too

[stuck palm]

do i have to make a var for that too then

[wintry quarry]

It needs to be copied, modified, then copied back

[stuck palm]

how do i copy it bback? theres no setter

[slender nymph]

for startRotation there is

just not main

[stuck palm]

am i doing this wrong 😭

[slender nymph]

assign to main.startRotationY not throwPuffs.main.startRotationY

[stuck palm]

like this?

[slender nymph]

yes

[stuck palm]

Okay tha k you !

[potent nymph]

playing with procedural mesh generation, and I was able to make a grid with some perlin noise for hills. The vertices that are in water are not displaced at all

I'm thinking about "hiding" the faces that are in the water, and I could do this by skipping creating a triangle when I loop over the grid

if I do that however, would that be a bad practice since I'll have a lot of extra vertices that are not assigned to any triangles?

[wintry quarry]

It would be best to not include the vertices that aren't included in any triangles, yes

[potent nymph]

okay, that makes things really tricky then, since with a grid the vertex indices are ordered and predictable, which makes assigning triangles as simple as having two for loops, one for columns and rows

but if I remove vertices, the indices get messed up :(

[wintry quarry]

Shouldn't be too hard if you do it in a second pass

[potent nymph]

there's a way to do that? I thought I had to assign the length of the vertex array from the beginning

[wintry quarry]

Run your current code. Put every vertex that's in a triangle in a HashSet. Afterwards you make a new array from those vertices

You'll have to just map the old indices to the new ones for the triangles

[potent nymph]

interesting. I don't know what a HashSet is so I'll have to look that up, but thanks for the tip 👍

[pearl lodge]

hey guys its been a while. I want to get back to game development. I want to take the snake game that I made and make it ONLINE multiplayer (currently I have local multiplayer). What is the best library/package to do this?

I've heard of NetCode. Is this the best one? or do you guys suggest anything else?

Thanks in advance.

[wintry quarry]

There's no "best" one. There are many frameworks all with their own capabilities, benefits, and drawbacks

[pearl lodge]

Do you have a short list (maybe top 3) so I can look into them?

[frosty hound]

Unity's netcode, photon and mirror

[wintry quarry]

Photon is a company that makes several frameworks btw

[meager gust]

check the origin of your model

if it's skewed off to the side, you'll need to fix that in blender or something

assuming that's what you mean

post a video of what's happening

when you click on your model, the box thing should be in the center of the model

for you, it looks like it's near the right arm. you'll have to fix that

[slender nymph]

your object is not centered on the parent that is being rotated

[meager gust]

or that

also if you're running this code in update, you don't need Time.fixedDeltaTime

change it to time.deltaTime

[sour fulcrum]

Is there a built in way to compare components and/or gameobjects from a prefab with the same one from a instance of that prefab?

eg.

    -GameObject Apple
        -MeshCollider

i wanna compare the meshcolliders and get a correct result

[inland canopy]

hello can anyone help me solve this error:
NullReferenceException: Object reference not set to an instance of an object
MouseDrag.OnMouseDrag () (at Assets/Scripts/MouseDrag.cs:24

[slender nymph]

how to debug a NullReferenceException for future use: https://unity.huh.how/runtime-exceptions/nullreferenceexception
your issue is that your camera is not tagged as MainCamera

[calm coral]

Do you have a camera in your game objects list?

[calm coral]

Oh, does it have to be tagged as MainCamera? Otherwise Camera.main doesn't work?

[slender nymph]

yes

[calm coral]

Aight, didn't know that, thanks!

[slender nymph]

https://docs.unity3d.com/ScriptReference/Camera-main.html

The first enabled Camera component that is tagged "MainCamera" (Read Only).

If there is no enabled Camera component with the "MainCamera" tag, this property is null.

[inland canopy]

Thanks mate for the help it worked

[calm coral]

Got it, thanks!

[nimble apex]

my task is to generate server log files for last three game session if any error occured
1 game session : start the game (run) to closing the game

the file generate will be like

• error1.txt
• error2.txt
• error3.txt sorta like this

i know how to obtain data and write files already, my worries are how to know this is the x times u opened the game

because how many time u opened the game, or nth game session is not recorded at all

[teal viper]

Then you'll need to record it. By game session you mean players joining the server or server starting and shutting down?

[nimble apex]

the definition of a game session in my case is when the run initiated , started , all the way to app termination

[teal viper]

For the client?

Or the server?

[nimble apex]

client app

[teal viper]

Ok, it would need to send some log in/out request and the server can keep track of each user session count.

[nimble apex]

i did come up with a solution, when the client started, i will do

int counter = PlayerPrefs.GetInt("nthsession");
    PlayerPrefs.SetInt("nthsession",counter++);```

maybe in game manager

public int nthsessionbase3 = counter/3 +1;```

[teal viper]

Storing it on the client side wouldn't be very reliable.

[nimble apex]

it is for debug only, for the whole dev team, so i was told to generate file locally

and using local data

[teal viper]

Okay

[queen adder]

Can we like grab the current active scene's yaml file to save the whole scene?

have anyone ever done a whole scene save system before?

[rocky canyon]

    private void HandleOrderRX(OrderRX orderRx)
    {
        float pitch = 1.0f;

        // Check if the orderRX is in our list
        if(order_rxs.Contains(orderRx))
        {
            orderRx.SetListeningForOrders(false);
            order_rxs.Remove(orderRx);
            pitch = .9f;
        }
        else
        {
            order_rxs.Add(orderRx);
            orderRx.SetListeningForOrders(true);
            pitch = 1.0f;
        }

        clickSounds.pitch = pitch;
        clickSounds.PlayOneShot(clickUnit);
    }```
not sure why this would error.

lol, hmmm nvm seems to have fixed itself.. i closed down my code editor and was gonna get 1 more screenshot of the error and I can't reproduce it again

[gray gorge]

Very noob question (smh my head):
I want to create a custom class MyButton that contains a string, KeyCode, Sprite, etc.
Next, in Unity, I want to assign all of these values in a [SerializeField] so that I can create an array of MyButton[].
Essentially, I’m getting

When what I want instead are empty boxes for me to fill in each instance variable for each button.

How do I do this? Or should I even do this at all (is this bad practice)?

    public string buttonName;
    public KeyCode keyCode;
    public Sprite buttonSprite;
    public Sprite buttonHeldSprite;```

[rocky canyon]

nope. its back.. it seems that If I have this script's inspector open it crashes when selecting and deslecting the unit..
but if i don't it wont.. 🤔

[slender nymph]

does your class need to inherit from MonoBehaviour? if not, then remove that inheritance, mark the class as serializable then you don't need to do anything else to make it work

[gray gorge]

oh yeah that makes sense thanks

[nimble apex]

Directory.CreateDirectory($"{Application.persistentDataPath}/ErrorLogs");```

this will not give me an error if the folder is created right?

[rocky canyon]

yup, thats it! when the inspector is open it causes the error.. along with a few other ones

[nimble apex]

its just do nothing?

[slender nymph]

correct
https://learn.microsoft.com/en-us/dotnet/api/system.io.directory.createdirectory?view=netstandard-2.1

Creates all directories and subdirectories in the specified path unless they already exist.

[nimble apex]

nice

[gray gorge]

fix works, thank you!

[round scaffold]

ive always wondered

if i make a class that inherits an interface

then i make another class that inherits from the first class

would the interface also be inherited?

[nimble apex]

  private void GenerateServerErrorLog(DateTime time, string code)
  {
    Directory.CreateDirectory($"{Application.persistentDataPath}/ErrorLogs");

    string path = $"{Application.persistentDataPath}/ErrorLogs/ServerLogs_{GameManager.Instance.nthErrorSession}.txt";

    //clear previous n-3th error logs 
    if (firstWrite)
    {
      File.WriteAllText(path,"");
      firstWrite = false;
    }

    //append all errors found in this game session
    using (StreamWriter sw = File.AppendText(path))
    {
      sw.WriteLine($"client server error found ! (code: {code}) >>> time : {time}");
    }
  }```

[slender nymph]

yes

[nimble apex]

finally got it done

[round scaffold]

hot

[slender nymph]

also this is a bit pedantic, but you don't inherit from an interface, you implement it

[round scaffold]

aighty

[nimble apex]

it doesnt add up the text tho

[plush chasm]

In C# is there a performance impact calling a method nested in another method? I used to use another language that had a pretty large performance impact to run a nested method so I've always been hesitant to nest methods in C#.

[teal viper]

Not enough to make difference in most cases.

Obviously, it's jumping pointers, so there is some overhead. But it's also possibly inlined by the compiler.

[slender nymph]

compiler turns local methods into internal/private static methods right in the class
https://sharplab.io/#v2:CYLg1APgAgTAjAWAFBQMwAJboMLoN7LpGYZQAs6AsgBQCU+hxTAcnQNyNNHnqu2dcCSLsQC+A8cOIC0mCnwFCRRAG4BDAE7oAHugC86AAwcpIvieXcKNfqZFLLTbWDAXLkppNFA=

[icy sluice]

Whats going on in here

[teal viper]

I wouldn't bother worrying about it, especially if it means sacrificing readability or modularity.

[north kiln]

StartCoroutine("<M>g__N|0_0")

telling people you can start local coroutines lol

[slender nymph]

oh no

[teal viper]

Oh, I though they were talking about nesting calls, not definitions(local methods)

[slender nymph]

it is also possible i misinterpreted their question. but one of us is probably right

[icy sluice]

Whats problem with that?

[plush chasm]

I didn't explain completely clear my question was more about referencing stuff in a method from a method nested inside

I felt there was probably some crazy stuff going on to pull that off

[icy sluice]

You dont know how methods work?

[gaunt ice]

local method i think, not calling other methods from method

[slender nymph]

that's demonstrated in the link i shared, actually.
the compiler generated a ref struct and the static method for that

[plush chasm]

I mean like what boxfriend linked

yeah I know

[gaunt ice]

just push/pop stack and change the pc in low level

[icy sluice]

Its not local, it needs to be static float/int/double...

[plush chasm]

still messing around with that to get a more realistic example but so far seems like it isn't a big deal

[slender nymph]

i also just realized i called the wrong method in the original link inside the N method. here is the fixed link that shows what is happening when you call that local method that accesses a variable inside the containing method
https://sharplab.io/#v2:CYLg1APgAgTAjAWAFBQMwAJboMLoN7LpGYZQAs6AsgBQCU+hxTAcnQNyNNHnqu2dcCSLsQC+A8cOIC0mCnwFCRRAG4BDAE7oAHugC86AAwcpImrRPLuFcwMF2r2sGEtXJTSaKA==

[icy sluice]

Ofc it isnt, depends on user how they want their code to look

I mostly put methods when i need to do some large calculus constantly

[plush chasm]

I renamed the stuff already since it was a bit confusing lol

[slender nymph]

yeah it's really not something worth worrying about tbh. any performance impact would be so small as to not actually matter for the most part. and if you have to micro optimize your code that much, you probably have other problems that you should be worrying about instead

[plush chasm]

yeah, thanks everyone

[slender nymph]

I was curious if this would actually work if you actually got the name of the compiler generated method. thankfully it does not so nobody has to try it ever again
https://paste.ofcode.org/ZnUguqYXnamz4FRMHQDufL

[north kiln]

lol, did you check if it was actually named that using reflection/decompilation?

[slender nymph]

got the name through reflection

[north kiln]

I presume Unity's reflection caching stuff doesn't capture compiler-generated methods like those

I would say that's good to know, but the only reason to know is curiosity 😄

[twin bison]

Should a player health script call the game manager when its 0 or should it call the player controller and the player calls the game manager?

[slender nymph]

weren't you going to use an event for that? what happened to that?

[shrewd swift]

Hi, what good methods would you recommend to read a .csv file ?
For now i thought about using StreamReader

also, my goal is to read this csv to make a jagged array. But I dont need to read & make this array each time I play. I just want to "convert" the csv to an array once in a while when I update the csv.
What would be a good "script writer" so i could "write" the array in my code or in another script, to avoid read & make this array each time I play ?

[twin bison]

Hi 😄 Yes you are correct but I think I overengineered it a bit with Hurtboxes and Hitbox etc now I want to refactor it. Im not sure if it makes sense if health script emits event and the player listens to it and then emits another event for the game manager. This thing gives me ptsd or something 😄

[shrewd swift]

i would go through player if player does stuff that gamemanager doesnt

[twin bison]

What about the health script calls the player controllers "Die" method and the player then invokes his "Died" event + additional stuff (eventually)? So only one event?

ah na then i have the problem that its not really reusable for enemy again, sorry I don't know which rabbit hole im going down there

[slender nymph]

unfortunately unity can't serialize a jagged array so you won't be able to just read the file and write its contents to a serialized field which would have been the most convenient option.
if you really wanted to avoid reading it at runtime (which if you just do once at startup really won't impact performance all that much) you could do something silly like use some editor code to read the file, then write some c# code to another file that includes creating the jagged array using the data from the file as hardcoded values.

there's probably some other ways you could do this at edit time but i can't think of any off the top of my head

[slender nymph]

just make the player invoke an event when the OnDead event is invoked from the Health component

you could have some method on your player controller that handles its death animation (if applicable), starts any other death effects, and then invokes its death event that your GameManager is subscribed to

[shrewd swift]

i was afraid of that, ty for the detailed response.
maybe i can do a in-between step ?
create my jagged array, make it to another format like json, serialize the json in a file (or field).
then at startup read this json (to avoid the writing of the array each time)

[slender nymph]

why. your data is already serialized as csv, right? so if your plan is to just deserialize it anyway just do it directly from that

[twin bison]

Ok what about this:

Enemy and Player and whow knows who else, in the future have this interface:

public interface IImmortal
{
    void Die();
}

The health script then has a reference to it:

public IImmortal body;

And the health script has this code:

if (amount <= 0)
            body.Die();

The Die method on my Immortals look something like that:

public void Die()
    {
        // other stuff
        Died?.Invoke(this);
    }

[shrewd swift]

i have to deserialize AND loop inside to CONSTRUCT the jagged array

so the csv is just the inputs to build the array

i can you give you an example if you want

[twin bison]

Oh *** my english - it sthould be "Mortal" not immortal 😄

[slender nymph]

one sec, i know of a free asset that should be able to handle the csv. just gotta find it again real quick

[shrewd swift]

my man

[slender nymph]

https://github.com/cathei/BakingSheet

[slender nymph]

i still think you should use an event on your Health component. a UnityEvent can just be hooked up in the inspector. that way your health component won't have to worry about whether your object is mortal or not, it just cares about the current value of the health

[shrewd swift]

ty

after some testing i realised that array can only have int as key, so i'll probably go with dictionnaries

[twin bison]

Oh UnityEvent ok, I used normal events aka event Action.. - I'll look into Unity Event

[twin bison]

this?

[slender nymph]

yep, or you could have kept using System.Action instead. this just allows you to subscribe to the event in the inspector

[twin bison]

yeah i like that more that i can just subscribe from the inspector and dont have to create an instance in the PlayerController

When to choose one over the other?

[slender nymph]

just depends on your needs for the event. i'd give something like this a read to better understand how to use events https://gamedevbeginner.com/events-and-delegates-in-unity/

Hello, i tried making 3D controlle, and it seem to work, but it always move at same axis..
I multiply input with Vector3.forwatd but still doesnt help..
https://gdl.space/funitehoyo.cs

[shrewd swift]

the answer is probably yes but do you already know if this library works well if double entries ?

[slender nymph]

1. don't multiply velocity by deltaTime, you're just making it unreasonably small for no reason and requiring you to increase your speed variable a hundred fold
2. use transform.TransformDirection to convert your input direction from local space to world space

[fringe plover]

okay, thanks

[bright zodiac]

local methods are nice, as long as you're not passing it around it won't create new object

[slender nymph]

no idea

[bright zodiac]

I wonder if local methods actually do calvirt under the hood or just the regular call 🤔

[slender nymph]

oh and you weren't even using your input variable which is where you were actually multiplying your input by transform.forward and transform.right

[fringe plover]

UHH, i didnt saw that._. thanks

[twin bison]

That was such a good read thank you very much, i think that answers all of my questions and thoughts

[pearl lodge]

@slender nymph could I possibly get your input on this?

[slender nymph]

please don't ping people into your questions. also my answer is the same as this #💻┃code-beginner message

[shrewd swift]

lets says i got a list of elements with a % chance

how would I do a random, and select the element ?

[wintry quarry]

weighted random selection algorithm

[teal viper]

Depends on how you want it to work. Do you want one item from this list to be selected, or roll for every on of them?

[shrewd swift]

my goal is to retreive one, but i dont understand what you mean with or roll for every on of them

[teal viper]

Since you have more that 100% total there, I thought there is a chance to get all the items at the same time.

[shrewd swift]

i will change that, it will be a total of 100%

i forgot to say that the number were used as an example

[languid spire]

real easy solution
make an array of 100 elements
add your different choices to the array the number of times the % should occur
random select from the array

[shrewd swift]

making multiple array of 100 elements is maybe to necessary ?

this would mean thousands of elements later on for me

[languid spire]

why would you need multiple arrays?

[shrewd swift]

because i am doing selection using probabilities and previous results
idk how to explain, but, here is a example of a table, there will be maybe 1 or 2 sub(and sub sub) tables for each cells

with this screen only, this gives me 100 * 5 elements in 6 arrays

[languid spire]

trivial if this is Enums of type byte its a miniscule memory usage

[shrewd swift]

i didnt decide yet if im doing enums or string, prob enum

[languid spire]

definitely enums, strings would be silly

[shrewd swift]

yes

[languid spire]

byte[100] * 6. Insignificant

[shrewd swift]

so byte[100] here is a list of 100 enum ?

[languid spire]

yep, if you declare your Enum as type byte

[shrewd swift]

what is the meaning of byte[x]

curious

[languid spire]

it's an array of bytes being indexed by x

[shrewd swift]

ah okay, thought it was something else

[shrewd swift]

how do I do that ?

[languid spire]

public enum MyEnum : byte

[shrewd swift]

if an enum is type of byte, what does it change compared to regular enum ?

[languid spire]

a byte takes up 8 bits, if you do not declare a type the default is int which is 32 bits

so the array will take 25% of the memory

[shrewd swift]

okay, but for basic stuff nothing change with the synthax of use of MyEnum ?

because i suppose there are cases where using int is usefull

[languid spire]

of course not, the only difference is the number of entries the enum can have, if you use byte then that is 255

[shrewd swift]

oh

then its great for my case

ty for answering my questions

[languid spire]

the only time I use anything other than bytes for enums is if I want flags, then I use ulong to give me 64 of them

[livid tundra]

I have these three Polygon Collider 2D components representing weapons being swung at an enemy.
I want to detect when the capsule collider on the enemy intersects this.

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

public class PlayerAnimationTriggers : MonoBehaviour
{
    private Player player => GetComponentInParent<Player>();
    private ContactFilter2D filter = new ContactFilter2D().NoFilter();
    private PolygonCollider2D[] attackColliders => GetComponents<PolygonCollider2D>();

    private void AttackTrigger()
    {
        List<Collider2D> colliders = new List<Collider2D>();
        if (player.primaryAttackState.comboCounter == 0)
            Physics2D.OverlapCollider(attackColliders[0], filter, colliders);
        else if (player.primaryAttackState.comboCounter == 1)
            Physics2D.OverlapCollider(attackColliders[1], filter, colliders);
        else if (player.primaryAttackState.comboCounter == 2)
            Physics2D.OverlapCollider(attackColliders[2], filter, colliders);
        
        foreach (var hit in colliders)
        {
            if (hit.GetComponent<Enemy>() != null)
                hit.GetComponent<Enemy>().Damage();
        }
    }
}

OMG, THIS WORKS 😳

however...

I am concerned that Unity might be computing intersections of all 3 colliders with each other when an animation event triggers.
All colliders are set to "triggers", btw

maybe there's no reason to worry about that 🤔

[languid spire]

why did you revert to your original structure?
think about what
Physics2D.OverlapCollider(attackColliders
does every time you call it

[livid tundra]

the charater has a 3-hit combo and each sword swing leaves a different silhouette, hence a different collider

[livid tundra]

As I understand it, this will be called on exactly one frame and will check if the indexed attack collider intersects with an enemy collider?

(with no incidence filter)

[languid spire]

it will execute the GetComponents every time, this only needs to be done once, in Awake

[livid tundra]

what? Why would it do that? I did that in line 8, I'm just trying to access the indexed element

[languid spire]

because that is the way you have coded it, it does what you tell it to do

[livid tundra]

I apologize for misunderstanding your earlier solution

[livid tundra]

"GetComponents" is in line 8

Physics2D.OverlapCollider(attackColliders[0], filter, colliders); is below

you're telling me that just checking overlaps gets components from the GameObject?

[obtuse cargo]

Hey im an roblox studio dev and now im trying unity useing c# i feel like im the must dumbass ever i worked on sum for an hour then i didn t save it ;((

[languid spire]

and is executed every time you reference attackColliders

[obtuse cargo]

any tips?

[livid tundra]

ok I do need to avoid that

what can I change to only do that once?

[languid spire]

exactly what I said before, move the lambda to Awake

[livid tundra]

I will try again, but the syntax was wrong earlier

[languid spire]

also as I said before, it should not be a lambda

[livid tundra]

I am still unclear, you are saying I should move the lambda to the Awake method, or that I should forego lambdas completely?

I should do straight assignment in Awake?

[languid spire]

void Awake() { attackColliders = GetComponents<PolygonCollider2D>(); }

job done

[livid tundra]

ok

it's not mad at me for this

let's see how this runs

[north kiln]

(that's not a lambda, that's an expression-bodied property)

[livid tundra]

wow, this is running like greased-lightning!

[livid tundra]

thank you so much!

[arctic harbor]

i'm trying to make some angled springs for a platformer. for some reason if the player jumps into the spring without any initial horizontal velocity, the spring won't apply any horizontal velocity either. ie i have a spring pointing up-right. if i just straight up into it, only my vertical velocity is changed. if i have a tiny amount of left/right velocity, then the spring will apply the right directed part of the velocity as well. i'm using Vector2 testVelocity = (Vector2)(transform.up * springPower); and other.GetComponent<Rigidbody2D>().velocity = testVelocity; where other is the player from OnTriggerEnter2D(Collider2D other). why might this be?

[livid tundra]

I am so surprised about two things still (and it's alright if you have better things to investigate)

1. why the lambda expression is causing the variable to redefine itself every time (fundamentals failure on my part)
2. why I can define an array without specifying its size and do assignment to it in Awake(). Is this because I don't know how many elements there are during definition or assignment?

[north kiln]

It's not a lambda expression

It's a property

[livid tundra]

oh

well is it pulling from the components list every time?

re-executing its definition?

[north kiln]

Properties are just methods, so you're just calling a method and doing the work repeatedly

[livid tundra]

ah

this makes sense actually

the array question is dumber ._.

...er.

[languid spire]

the array question is simple, you declare the array, GetComponents defines it and returns the result

[livid tundra]

got it

thank you

wow, I thought for sure I broke my tutorial

but I actually improved it

(with your help)

[languid spire]

lol

unfortunately, as with many tutorials, that is not difficult

[livid tundra]

trickiest part is anticipating what I should wait to see if he fixes later or what I should immediately improve myself

before it gets too coupled to other systems

(despite their best efforts not to)

this is a better-than-most tutorial imo

[languid spire]

remember the old saying
'In the land of the blind the one-eyed man is king'

[arctic harbor]

this is what it looks like. you can see it only boosts me horizontally if i already had horizontal velocity to begin with

[teal viper]

Can you share more of the coffee?

    }```

[teal viper]

And are you modifying the character velocity anywhere else?

Ah, you're only setting the vertical velocity here

[arctic harbor]

well, no. the spring is angled

it's facing up and right

[teal viper]

Ah ok.

Then what I said earlier

[arctic harbor]

and that doesn't explain why it applies the horizontal velocity only if the player already had an initial horizontal velocity

[arctic harbor]

the only things that affect the player velocity are user input (wasd/arrow keys) and the springs

[teal viper]

It probably does.

[teal viper]

Can you share that code?

[wintry quarry]

Probably your player movement code overwriting it

[languid spire]

really you should not be doing this

other.GetComponent<Rigidbody2D>().velocity = testVelocity;

you should pass testVelocity to a component on the player and let that deal with it correctly

[arctic harbor]

how does one do that

[teal viper]

playerReference.DealWithIt(yeetVelocity)

[languid spire]

well if you have a playerMovement class, use that, add a method that will take the velocity as a parameter and integrate it with you current player velocity

[arctic harbor]

this was it i had something that would set player velocity to zero after damping caused it to drop below a very small threshold

[languid spire]

single responsibility principle, break it and it will bite you in the arse every time

[arctic harbor]

by single responsibility here, do you mean that if i want to change the player's velocity, it should have a method to do it so anything else that wants to change the player's velocity will call that?

[languid spire]

yes, playermovement should only be changed by playermovement

[arctic harbor]

i'll keep that in mind, thanks. not sure if that particular bit would have mattered in this issue here. i had

        {
            rb.velocity = new Vector2(0, rb.velocity.y);
        }```
in PlayerController in FixedUpdate. my spring logic is in an OnTriggerEnter2D.

[languid spire]

it would have done because you could have seen in one class that different things were affecting eachother

[arctic harbor]

...it just dawned on me that if i wanted to set the velocity to zero after i was sufficiently slow enough i could have just checked the velocity itself rather than using an extra variable to check the previous position...whatever that's old code idk what i was thinking at the time. unless i actually did try that at the time and fsr it didn't work how i wanted

[autumn plover]

My bad, i didnt know that i have to do this

[languid spire]

yours clasifies as large

[autumn plover]

Hi Guys,
I needed some help with my AR project. In my project I have a Sling Arm and a Ball, one button when pressed destroys the hinge joint between the Sling Arm and the Ball, and there is another Reset Button when pressed I want it to put the arms back in original position along with the ball and the hinge joint between the sling arm and the ball should be reset. Unfortunately if I destroy the hinge joint, I cannot create another hinge joint between the two objects. Does anyone have any way to overcome this issue?
I have provided my code below, if anyone finds a solution to this, could you ping me or DM me as I really need help and am stuck solving this issue since some time!
Thanks!

Code: https://gdl.space/xocoborasu.cs

[languid spire]

why are you adding llsteners in Update?

[autumn plover]

When I add the listeners to the start function and run the project, the buttons don't work for some reason.... I do not know why this happens

[languid spire]

well doing it in Update is a very bad idea so I guess you start with figuring that out

[autumn plover]

Okay, ill try to figure that out, but is there any way to solve the hinge joints issue?

[languid spire]

yep,

        HingeJoint hingeToDestroy = Ball.GetComponent<HingeJoint>();
        if (hingeToDestroy != null)
        {
            Destroy(hingeToDestroy);
        }

        HingeJoint newHingeJoint = Ball.gameObject.AddComponent<HingeJoint>();

aint gonna work, you will need to wait 1 frame before creating a new joint because Destroy takes that long to run

[autumn plover]

Thanks, I'll try to fix this.

[livid tundra]

I'm struggling to set the sprite renderer color parameter via ternary operator

sr.color = white ? sr.red : Sr.white;

When I try this, I get an error that says can't implicitly convert bool to color

[frosty hound]

What type is white?

[languid spire]

Color.white

Color.red

all the info you need https://docs.unity3d.com/ScriptReference/Color.html

also sr and Sr ?

[livid tundra]

sorry, I was uh...elsewhere when I typed that. This first line is what causes an error:

private void RedColorBlink()
{
    sr.color = Color.white ? Color.red : Color.white;
    if (sr.color != Color.white)
        sr.color = Color.white;
    else
        sr.color = Color.red;
}

the if/else worked fine

I thought a ternary operator would be nifty

sr := SpriteRenderer

[languid spire]

sr.color = (sr.color == Color.white) ?

it needs to evaluate to bool

[livid tundra]

oh, no kidding

I see thank you

@languid spire private void RedColorBlink() => sr.color = (sr.color == Color.white) ? Color.red : Color.white;
😄

or 😱 ?

[languid spire]

fine, not the way I would do it but, fine

im doing this to get a folder but when i build my project it gives me this error: DirectoryNotFoundException: Could not find a part of the path 'C:\Users\patbr\Downloads\testingGame_Data\Resources\Worlds'. How can i fix this?

[languid spire]

Missing Assets\ ???

[cerulean quest]

when i input something onto a function does it make a copy of the the thing, or does it take the orignal? cuz i am used to c++ where you put an & to indicate that you want to put the orignal copy into the functions

[shrewd swift]

~~i cant fix this issue, screen is located in a function

i dont even see how there is an issue, the var is delcared in same scope~~

forgot that i have to init with values

[timber tide]

well, similar concept applies but you should research passing by reference and value types

[cerulean quest]

ok but how do i control if its a reference or a copy

adding & gives me an error

[timber tide]

you don't use &

[cerulean quest]

yeah what do i use?

[fossil drum]

By default it's a copy, and if you want to reference it just use ref in the signature afaik.

[cerulean quest]

ok thx

[fossil drum]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/ref

In a method signature and in a method call, to pass an argument to a method by reference.

[zinc warren]

How come it works in dev environment

[fossil drum]

But afaik this doesn't change anything when you pass it to a method?
Both reference and value types are copies by default to a function right?

[timber tide]

right default behaviour is just passing the object without & as it's implied in c# if not value types

[cerulean quest]

i need to edit an array inside a function

[fossil drum]

Knowing the difference is indeed a good idea for C#, I agree with that.

[timber tide]

ref is useful when you do want to pass the value type in but not make a copy of it such that editing it inside of the method does not need to be passed back

[cerulean quest]

yeah thats what i need, to edit the args inside the func

[languid spire]

that path will not work anywhere, presuming your Resources folder is within the Assets folder

[charred spoke]

Arrays in c# are reference types you just need to pass them to the method and inside the method you will modify the original array

[cerulean quest]

oh yeah true i forgot arrays are just addressess

[zinc warren]

It does work when testing but once I build it stops works

[languid spire]

show the code where this is being used

[slate gale]

I'm trying to rotate my player towards a target in the Y-axis using lerping. This pretty much works, but sometimes it rotates the 'wrong' way, as in, it takes the longer rotation over the shortest rotation. E.g: if clockwise would be faster to rotate, sometimes it still picks counter-clockwise. Anyone got any hints for me to fix it?

player.localEulerAngles = new Vector3(0, Mathf.Lerp(player.localEulerAngles.y, playerTargetY, cameraTargetRotationSpeed * Time.deltaTime), 0);

[zinc warren]

https://pastebin.com/vzkkcpka

public static string WorldDirectory = Directory.GetCurrentDirectory() + "\\Assets\\Resources\\Worlds\\";

[languid spire]

don't rely on eulerAngles from the transform, 99% of the time they are not what you think they are

[slate gale]

so you recommend just using transform.rotation with new Quaternion()?

Quaternion.LookRotation doesn't rly work for me so I decided against that btw

[languid spire]

ok, so this

public static string WorldDirectory = Directory.GetCurrentDirectory() + "\\Assets\\Resources\\Worlds\\";

is not this

C:\Users\patbr\Downloads\testingGame_Data\Resources\Worlds

is it?

[zinc warren]

it is for the build version
i also tried doing this and it still didnt work

public static string WorldDirectory = Application.dataPath + "/Resources/Worlds/";

[languid spire]

what? it just randomly decides to drop the Assets/ part?

[fringe plover]

Hi, I’m making 2D platofrmer, and I need help._.
To make movement I’m using this:
rb.velocity = new Vector2(move*speed, rb.velocity.y)
But when I tried to make dash mechanic or smth like this by adding X force it just ignored it, so, what should I do?

[languid spire]

Anyway you should be using persistentDataPath for runtime

or streamingAssets Path

[zinc warren]

well when i build it into my downloads folder it works and then when i create a folder in the downloads folder and move the files into there then it gives me the error DirectoryNotFoundException: Could not find a part of the path 'C:\Users\patbr\Downloads\New folder\Assets\Resources\Worlds'.

[languid spire]

dont use Directory.GetCurrentDirectory() use https://docs.unity3d.com/ScriptReference/Application-dataPath.html

[zinc warren]

so

public static string WorldDirectory = Application.dataPath + "/Resources/Worlds/";
```?

[languid spire]

use Path.Combine

[slender cargo]

Quick question really.... This is on a pre-fab which has a different name, how can I find the text UI which is within the pre-fab?

This is throwing an error

Or would an easier way be to find a game object with the name "PlayerIndicator"?

Although I will have 2 of them in the scene at the same time, so that Won't work

[languid spire]

GetComponentInChildren ?

are you sure you need Text not TMP_Text ?

[slender cargo]

Yeah, I use legacy text componenets, I prefer them ahaha

[slender cargo]

ah I'll try this out

This didn't work either

[slender cargo]

Awesome, that worked well!

I was unaware that this existed.

[zinc warren]

    public static string WorldDirectory = Path.Combine(Application.dataPath, "Resources", "Worlds");

i still get this error DirectoryNotFoundException: Could not find a part of the path 'C:\Users\patbr\Downloads\New folder\testingGame_Data\Resources\Worlds'.

[stuck palm]

How come if I use get component and an object doesn't have that component an error doesn't happen until I try to use that component

[timber tide]

because it returns null

[charred spoke]

Because thats just how it works

[timber tide]

I suggest just use TryGetComponent and check if it's null right then

[charred spoke]

TryGet returns a bool if the component is found so no need for a null check

[timber tide]

right right

[slate gale]

nvm i got a fix

float lerpedY = Mathf.LerpAngle(player.localEulerAngles.y, playerTargetY, cameraTargetRotationSpeed * Time.deltaTime);
player.localEulerAngles = new Vector3(0, lerpedY, 0);

[polar acorn]

So you can check if an object has a component

[languid spire]

So if you navigate to
C:\Users\patbr\Downloads\New folder\testingGame_Data\Resources
in File Explorer do you see a Worlds folder there?

[zinc warren]

no

[languid spire]

do you ever create one?

[zinc warren]

well its in my resources folder

[languid spire]

The Worlds folder in the project is only accessible using the Unity Resources API, not the .Net File Api

[dim halo]

I added a collider to my object, but the bird still gets through it, I would appreciate any kind of help>>

[polar acorn]

https://docs.unity3d.com/ScriptReference/Resources.Load.html

[languid spire]

he's writing as well at runtime, that's a no-no

[polar acorn]

How are you moving the object

[dim halo]

ok so basically I was watching a tutorial, however, because of Im stupidity I forgot to add the part where he adds collision to the object

later on, I wanted to add by myself

I did add collusion2d

But the bird still gets throuh

gh

[dim halo]

wdym

[polar acorn]

I mean how are you moving the object

[dim halo]

in the scene, I dont have it

[polar acorn]

Don't have what

[dim halo]

as you can see, in the seen I dont have the pipe image

[polar acorn]

So if your problem is that you aren't colliding with the pipe the answer is probably because you don't have a pipe

[dim halo]

I do have it in the gameplay

Can I call?

to be more specific

it spawns

like in the game of flappy bird

[polar acorn]

No

Okay so then how are you moving the object you've still never said

[dim halo]

i just wrote the stuff in the script

it spawns

also gets deleted

[cosmic quail]

if u dont want the bird going through the pipes, then you need a collider on both of them and a rigidbody on the bird, and you have to move the bird in the code with the rigidbody (not transform.position or translate)

[dim halo]

after it crosses the deadzone

[dim halo]

I did just add the collider to the pipe

nonetheless, the bird still gets through it

[cosmic quail]

what about the other things i said

[polar acorn]

How are you moving it

[dim halo]

for the bird rigid body

it says none (rigidbody 2D)

[polar acorn]

[polar acorn]

Are both objects at the same Z position

[dim halo]

I can see the z position of the pipe

However I cant see it for the bird

Furthermore, i cant add a component to it

usually in the bottom of the inspector scene

There is a box where I can add component

now there is none

[cosmic quail]

ur just clicking on the image and seeing the image data for your bird. you gotta click on the bird inside the scene

[wintry quarry]

Do you have your hierarchy window open? You should open it

[dim halo]

No, I clicked on the bird image next to the birdscript

[polar acorn]

Show the inspector of the bird object

[dim halo]

okay

[fringe plover]

i tried porting code from 3D, whats wrong?

[dim halo]

the inspector of the bird object

[polar acorn]

2D raycast has different parameters than 3d, check the documentation for it

[cosmic quail]

no. thats just your bird image

[polar acorn]

I said the object

[dim halo]

yes, the one next to the birdscript is the object

I clicked on that one

[cosmic quail]

https://docs.unity3d.com/Manual/Hierarchy.html you need this. did you delete this window

[lunar grove]

Anyone why my serializable field is not outputting the Product from my script code

[polar acorn]

None of these are objects

[dim halo]

Should I click on the birdscript?

[polar acorn]

These are assets

[dim halo]

wait

my bad

sorry

[polar acorn]

Open the object

[dim halo]

ok sorry

the left window

[gusty sorrel]

i have a vertical fuel tank, and an engine at the bottom connected by a fixed joint and an upward force is applied to the engine. for some reason the thing starts tilting to one side after lifting off and after a few seconds it flips over. anyone know why could this be?

[languid spire]

It was built by SpaceX ?

[rocky canyon]

is the Center Of Gravity in the middle?

[lunar grove]

public float characterGravity = 9.81f * 2f;

However serializable field shows 9.81 still

[rocky canyon]

Center of Gravity is calculated by the colliders

[dim halo]

bird object

[rocky canyon]

if they are offset to one side it will tilt

[gusty sorrel]

its a simple cylinder and cube at the bottom and they are perfectly aligned

[languid spire]

did you change the code after creating the script?

[lunar grove]

I have saved the code and Unity should have applied the changes

[rocky canyon]

are you sure they perfectly aligned? select both of em and check ur center pivot

[rich adder]

wrong

[polar acorn]

Okay so it's at Z=0, and from your previous screenshots your pipes are not. Put the pipes at Z=0 as well

[languid spire]

does not work like that, once a script has been serialized, the Inspector values take precedence over the code values

[dim halo]

okay

[polar acorn]

The entire point of the inspector is for you to provide values that override the defaults from the code

[lunar grove]

I mean that was the default code

from when I first put it into a serializable field

[polar acorn]

If the code overwrite the inspector every time the code changed the inspector would be worthless for assigning values

[dim halo]

okay

[polar acorn]

Yes and any new instances you add will have that as the default

[polar acorn]

This has nothing to do with you

[dim halo]

ah ok

Ok I did change the z

[polar acorn]

It was literally a reply to someone else

[dim halo]

sorry

it is now identical with the birds (0)

[gusty sorrel]

im a complete beginner so i dont understand what those options do

[lunar grove]

Fixed it I removed and readded the component back to the Player GameObject, the 9.81 of default wasn't my original intention soo

thanks for the replies and help though!

Oh wait this si what you literally said lmao

[gusty sorrel]

increasing drag somehow fixed this

[dim halo]

the bird stills gets through it

[cosmic quail]

show what u got inside birdscript

[dim halo]

okay

Im so confused

I did add the collusion

to the pipes

the bird still gets throuh

gh

[cosmic quail]

maybe your collider is offset or something and its not actually on the pipe. if u click on ur pipe it should show a green outline for where the collider is. is it in the right place? and can you check the bird's collider as well?

[dim halo]

okay

[cosmic quail]

if u dont see it then u gotta click on "edit collider" maybe to see it

[polar acorn]

How are you moving the pipes

[dim halo]

i can move them

from the scene

FINALLY

YEEEEES

IT WORKS

thx @polar acorn @cosmic quail

appreciate the help

[cosmic quail]

how did u fix it? was it the colliders being wrong or what?

[slate gale]

Oncollisionstay is a unity method you can’t just call it

[dim halo]

I was trying to add colider to the pipe spawner

I had to add it to the pipe clone

to both of them

the upper and bottom one

[slate gale]

Similar like void start update awake ontriggerenter etc

[dim halo]

nope

not the clone

[cosmic quail]

oh ok. glad you solved the problem!

[slate gale]

Ait cool

[dim halo]

sorry i mean the top pipe and the bottom pipe

[cosmic quail]

ok

[rocky canyon]

yup yup, makes sense

[novel dagger]

first game

not done tho

[frail star]

I'm sure it's something simple I'm missing , I have a float value that stays between 0 and 1. I try to add to the value while it's decrementing in a coroutine and It doesn't increase the value while it's decrementing

public void ModifyHappiness(float amount)
{
    currentHappiness = Mathf.Clamp(currentHappiness + amount, 0f, maxHappiness);

    OnHappinessChanged?.Invoke(currentHappiness);
}

private IEnumerator DecreaseHappinessOverTime(float durationInSeconds)
{
    float startTime = Time.time;
    float initialHappiness = currentHappiness;

    while (Time.time - startTime < durationInSeconds)
    {
        float elapsedTime = Time.time - startTime;
        float progress = elapsedTime / durationInSeconds;

        currentHappiness = Mathf.Lerp(initialHappiness, 0f, progress);

        yield return null;
    }

    // Ensure the final happiness rate is exactly 0
    currentHappiness = 0f;
}

// Used with ui Button Like this --> happinessButton.onClick.AddListener(() => ConsumeHappiness(.05f));
public void ConsumeHappiness(float happinessAmount)
{
    ModifyHappiness(happinessAmount);
}

[polar acorn]

I don't fully follow your question, but the coroutine is going to overwrite whatever value you get from ModifyHappiness if those happen during the decrease

[frail star]

Yes I'm trying to modifyHappiness during the decrement

I'm trying to add to it

[polar acorn]

The coroutine sets currentHappiness to a function that is dependent only on the starting value and the time elapsed

[frail star]

So this line is the culprit

currentHappiness = Mathf.Lerp(initialHappiness, 0f, progress);

[polar acorn]

Actually it seems more like the design is the culprit. You've created a system that decreases the happiness to zero in some specified amount of time, then you expect to add happiness after the fact. This is a contradiction - one of them assumes the drain happens in constant time, the other assumes it's at a constant rate, and they cannot both be true

You would need to either have the coroutine subtract an amount over however long it takes to reach 0, or you'd modify the time to reduce the drain rate

[frail star]

I was decrementing with a rate , like here
#💻┃code-beginner message

[fringe kindle]

How do I disable a collider for a few seconds after exiting it?

[rich adder]

make a reference to it , then a timer

coroutine is easiest

[fringe kindle]

It's so I don't go back into it after jumping off the vine

[frail star]

Looks like this answer is what I would want
https://gamedev.stackexchange.com/questions/121749/how-do-i-change-a-value-gradually-over-time

[fringe kindle]

what's that? never heard of it before

[frail star]

https://gamedevbeginner.com/coroutines-in-unity-when-and-how-to-use-them/

[rich adder]

its just a way to make timed events
https://docs.unity3d.com/ScriptReference/Coroutine.html

[swift crag]

A coroutine lets you run code that "waits"

[rich adder]

Indeed.

eg

public Collider colider;
public float waitTime = 3f;
IEnumerator TimedEvent()
{
    colider.enabled = false;
    yield return new WaitForSeconds(waitTime);//wait 3 sec
    colider.enabled = true;//enable it
}```

[fringe kindle]

ahh

Cheers

[rich adder]

Note you need StartCoroutine to call it 🙂

[fringe kindle]

Where abouts would I need to put it?

[rich adder]

whenever you want timed event?

[frozen stream]

so im making a auto scrolling platformer and I want the player to die if it gets to far to the left off screen, how would I get the camera's edges to place triggers right off screen?

[polar acorn]

Put a trigger area that moves with the camera and kills the player if they enter it

[frozen stream]

yes, but how do I get the camera's view's edges (the edges of the screen) and make that into world coordinates for the colliders?

[wintry quarry]

I'd do it the other way around. Zoom the camera such that it fits the colliders.
Otherwise people with different aspect ratio screens are playing a different game

[frozen stream]

but if i knew the cameras edges, then the aspect wouldn't matter, because the colliders would always be at the edge?

[desert elm]

2D Raycasts should interact with this edge collider, right?

[ripe shard]

You can get the frustum planes of a camera. https://docs.unity3d.com/ScriptReference/GeometryUtility.CalculateFrustumPlanes.html

[wintry quarry]

yes, if your raycast actually hits it

[frozen stream]

@ripe shard I don't think I understand this documentation

[desert elm]

Right- and the DrawRay should also stop at the edge collider, right?

[wintry quarry]

There's 3 raycasts in this screenshot, and one of them isn't visible. It's unclear which one you're talking about. and no, there's nothing in there stopping the DrawRay at the hit points, they seem to be drawn to viewRange always

this looks like it should all be in a loop

instead of 3 separate nested raycasts

[desert elm]

it is

[wintry quarry]

I mean a loop instead of repeating code 3 times

[desert elm]

well, I need to measure the distance and multiply said distance
if the raycast is going through a specific area in the game

right- is there a way to make a tag selectable from the inspector?

[swift crag]

What are you trying to accomplish?

Not "shoot three raycasts"

[wintry quarry]

A custom inspector/property drawer with https://docs.unity3d.com/ScriptReference/EditorGUI.TagField.html

[swift crag]

what is this, logically, supposed to be doing?

[wintry quarry]

Or using NaughtyAttributes: https://dbrizov.github.io/na-docs/attributes/drawer_attributes/tag.html

[sleek notch]

I would like to stop at 15 degrees but it won't stop anyway and also if elevation is 0??

[wintry quarry]

rotation.x is not what you think it is

Debug.Log

[polar acorn]

Well, since rotation is a normalized Quaternion, and elevation is presumably something higher than 1, it is impossible for this condition to ever be false

[sleek notch]

It is. Because if I go up the number raise up

[wintry quarry]

it isn;t

Debug.Log(cann.transform.rotation.x);```

you will see

[sleek notch]

I did this to see it

[polar acorn]

https://docs.unity3d.com/ScriptReference/Quaternion.html

[sleek notch]

I'm saying it raising up

[eternal needle]

What you see in inspector isnt what that value is

The inspector shows you euler angles

[sleek notch]

0.15

oh inspector

[polar acorn]

That is not fifteen degrees

That's one component of the four-dimensional vector expressing a specific orientation

[sleek notch]

I know but for example

This is inspector somehow Y raising up and X is still

Wait sorry

Cannon. My bad the X is raising with cannon

[wintry quarry]

your whole approach to this is faulty.
do this:

if (Input.GetKey(KeyCode.W)) {
  Quaternion target = Quaternion.Euler(elevation, 0, 0);
  cann.transform.localRotation = Quaternion.RotateTowards(cann.transform.localRotation, target, cannonSpeed * Time.deltaTime);
}```

[desert elm]

I want there to be a specific area in the game that is "harder" to see through, and I want to simulate this by measuring the distance between the target and whatever it wants to look at with a raycast
if the raycast enters/hits the collider of the specific field, then I want it to stop, and send out another raycast.
If it hits/reaches the target, then the distance will be tallied up, and the distance inside the area of the edge collider ( with the tag forest ) will be multiplied

if it instead hit the edge of the collider again, then I want it too tally up the distance with the multiplication, and repeat the function, now starting from where the second hit occured

[sleek notch]

Ok thanks it's working. I'll see tutorial about it

[desert elm]

changed the code

my main problem is that the first raycast doesn't appear to interact with the edge collider, even if I have this enabled

or hell, the raycast doesn't appear to interact with anything for that matter

can't even hit normal colliders

[wintry quarry]

If you have startPosition and endPosition then Raycast is overcomplicating things. You should use LineCast. It was made for that

Also you're drawing the ray with viewRange here but not considering viewRange in the raycast itself

[desert elm]

because the raycast will only fire if the target we want to see is withing viewrange already

but I draw it with view range to reduce visual clutter

[wintry quarry]

but you would want to actually limit the raycast to that distance then

otherwise the default raycast distance is infinite

[desert elm]

okay sure-
but is there an error with the code that stops the raycasts from interacting with any collider?

[wintry quarry]

presumably your ray is simply not intersecting the collider.

[desert elm]

it clearly is

[wintry quarry]

your code is checking for a specific tag

does that object have that tag?

[wintry quarry]

if (hit) {
  Debug.Log($"Hit an object with tag {hit.collider.tag}");
}
else {
  Debug.Log("Hit nothing");
}```

[desert elm]

yes

[wintry quarry]

Try this quickly and see what it says if anything

[novel hemlock]

where is my canvas going?

[wintry quarry]

double click the canvas object in hierarchy

[desert elm]

thanks

[novel hemlock]

oh sorry i fixed it, turns out the canvas was a child of the camera

[desert elm]

huh

I found the problem, the raycast was starting inside the collider

I assume that this shouldn't be happening

[buoyant knot]

physics queries can be weird right at the boundary of the collider if you need high precision because then the little parameters make a difference

[earnest tendon]

im atempting to create a script that can access another script to give a knife object some stats but im running into this issue and i got no idea how to solve it

[polar acorn]

Save your script

[earnest tendon]

oh

[sage mirage]

Hey, guys! I want to set a particle effect to my player, so whenever player transform changes to have the particle effect to the changed player position. How to do that?

[wintry quarry]

make it a child of the player

[sage mirage]

Yes but where to put my Instantiate() because I am using instantiation for that.

[wintry quarry]

It doesn't matter where you put Instantiate, but you should use a version of it that takes a Transform parent paremeter:
https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

[sage mirage]

Yeah I know that! I was using Object, Vector3, Quaternion I was wrong? I have to use that one you say?

[wintry quarry]

This one has all that plus the parent param

[sage mirage]

Ok!

[noble garnet]

I do have a issue with my 3d game. when ever I turn left or right it will form a circle instead of going straight to left or right. Is there any solution?

[timber tide]

yes, don't rotate

[desert elm]

so I have a memory leak- any ideas on why?
I know its because of recursion/repeating the method inside itself, but I see no reason why it would repeat itself so much that there would be a memory leak
in this case, it should only repeat 1.5 times

[halcyon summit]

Is there a best practise for where to store the level at which an item becomes unlocked? Does it belong in a Scriptable Object, in a dictionary, or maybe as a variable on the prefab of the item? Or just done to preference?

[timber tide]

Dictionary with the item/type reference and bool should be fine

[swift crag]

I would store unlocks as data separately from the item

[shrewd swift]

Hello guys, i got some questions regarding declaring and initializing lists.

When declaring the variable

List<float> somelist;

we can initialize its content :

List<float> somelist = new List<float>();
// (1) i suppose this creates an empty list

List<float> somelist = new List<float>(){
        10f,
        4.5f
    };
// (2) sets some values when init

but if i dont want to add some values right at the beginning, does doing some methods like varname.Add(item) error ? or will c# automatically construct a empty list then do the method ?

why would i do new List<float>() if i dont prefill ?

[swift crag]

how I'd do that is up in the air

it could just be a single list of item-level pairs, or a list of "UnlockInfo" scriptable objects

[swift crag]

Lists resize themselves.

They aren't fixed-size like an array is

[shrewd swift]

yes, they double each time we go above its limit right ?

[swift crag]

You need to construct the list so that it exists, though

[rich adder]

you do new() so its not null

[swift crag]

List<float> x;
x.Add(3);

This is bogus. x doesn't refer to a list.

it will be null

[stuck palm]

why isnt my particle system playing? its printing the print to the console, but i cant see any particles being played

[swift crag]

An empty list is very different from a list that doesn't exist

[shrewd swift]

ah okay, because sometimes i got no object references, i wondered why

so except if i SET the list, i have to construct it so its an actual list ?

[swift crag]

note that this use of rotation is wrong

you should be doing transform.eulerAngles.x, etc.

[swift crag]

If you want to use the list, you must ensure that you actually have a list

you could construct it in the field initializer, or construct it right before you use it

(and if it's serialized by unity, it'll be initialized to be an empty list, too)

[shrewd swift]

ok ty guys

[swift crag]

[SerializeField] List<int> foo;
List<int> bar = new();
List<int> baz;

void Start() {
  baz = new();
  foo.Add(1);
  bar.Add(2);
  baz.Add(3);
}

All three of these will behave correctly.

[shrewd swift]

i see

[swift crag]

It's possible that the system is getting stopped soon after it plays. Make sure that isn't happening

[shrewd swift]

so [SerializeField] was the reason why sometimes it was throwing an error and sometimes no

[swift crag]

(log when you call Stop, basically)

[swift crag]

Yeah.

[shrewd swift]

ty

[swift crag]

Sometimes I initialize the list myself anyway

It looks a bit weird to see a list that I appear to never construct

that's just personal preference, though

[stuck palm]

thanks! in regard to the euler angles, i tried applying it to these circles, for some reason no matter what it just faces z

[swift crag]

(in that case, C# will construct an empty list as the object comes into existence, and then Unity will overwrite it)

[swift crag]

That could be an issue with how the particles are being rendered

I don't remember the specifics off the top of my head, but I know there are different ways to draw them

Also, make sure you have 3D rotation enabled

[stuck palm]

it wasnt turned on....

[swift crag]

That'll do it -- the system was using the "Start Rotation" float field instead

[shrewd swift]

can I ask here a question regarding the usage of a unity package ? (not built in)

or should i go in #↕️┃editor-extensions

because its a code usage problem

[stuck palm]

i added a print to the stop function and it never got called so

idk whats happening here

[wintry quarry]

#↕️┃editor-extensions is for when you're making editor tools usually

[shrewd swift]

ah okay

well i found out my issue

[deft monolith]

Hi! Having trouble wrapping my head around quaternions. I'm just trying to rotate my cube either 90+- degrees in the X or Z world axis. But when i first rotate X, and then rotate Z, its being rotated in the local Z axis instead of world Z axis. I dont know how to get it to use the world axis here. I know the issue but not the solution.

The GetRollRotationX/Z just returns -90 or +90 depending on direction.

[wintry quarry]

trying to use euler angles in isolation like that is a bad idea

you can't take 1/3 or 2/3 of the euler angles and reuse them with some other angle. They come as a set of 3 or not at all

due to gimbal lock

You'd probably be better off not using them at all

[deft monolith]

Yeah.. Been trying to solve this for three hours now lol. Im aware of the transform.rotate method but giving it the correct data on how much to rotate per iteration is difficult

Yep im aware of gimbal lock, thats almost whats happening,

[wintry quarry]

the simplest option is usually:

Quaternion targetRotation = /* calculate target rotation as a quaternion here */
while (...) {
  // blah blah
  RotationObject.transform.rotation = Quaternion.RotateTowards(RotationObject.transform.rotation, targetRotation, Time.deltaTime * speedInAnglesPerSecond);
}```

e.g.
Quaternion targetRotation = RotationObject.transform.rotation * Quaternion.Euler(90, 0, 0); to do a rotation of 90 degrees on the x axis

[deft monolith]

Ah okay! I'll give that a shot, thanks 🙂 I'll need to think about how to use my RotationCurve (animation curve) instead of the angles per second.

[wintry quarry]

you would use Quaternion.Slerp in that case

instead of RotateTowards

if you know how to use it

[stuck palm]

@swift crag think i discovered the issue, put it in update and this is happening

[polar acorn]

Turn off collapse so you can see the order

[stuck palm]

its in this sort of pattern

[polar acorn]

So then yes it is stopped

[buoyant knot]

what will help is to understand that you have to actually apply rotation operators

[stuck palm]

i dont understand why tthis happens, this is on a moving object that is travelling through the air

[buoyant knot]

quaternion multiplication is equivalent to applying one quaternion’s rotation operator to another

[polar acorn]

It's happening because rb.velocity.magnitude is less than or equal to 10

[stuck palm]

but it shouldnt be, i dont understand why cus when i look at the inspector, it shows up as like 30 or 50

[buoyant knot]

eg if you want to rotate by +90 in x, and then +90 in y, you cannot set new rotation to (90,90,0). It’s just incorrect, and the order of rotations matters

[polar acorn]

Log the value

[buoyant knot]

you’d want to take (+90 y rotation) * (+90 x rotation)

[polar acorn]

So you know what it is at that precise moment

[stuck palm]

just realised that it might be saying stopping because there are like 6 other items of the same type in the scene... now its constantly saying playing

[stable ore]

how to get rid of dis?

[timber tide]

speaking of gimble lock and quaternions, spent like a few hours debugging because I had to flip some quaternions from lefthand to right of my operator

and I still have no clue why

[wintry quarry]

it's called "CodeLens" in the settings

[stable ore]

is it in vs or unity?

[wintry quarry]

VS...

[stable ore]

alr

[polar acorn]

Well which program do you see it in

[stable ore]

unity

[wintry quarry]

Quaternion composition is not commutative!

[polar acorn]

Really? Show a screenshot of your unity window with that line visible

[timber tide]

[stable ore]

im being sarcastic...

[stuck palm]

i dont know why this particle system isnt playing, its filling all the requirements to start playing

[polar acorn]

Where do you set fast

[desert elm]

right so-

i assume that the memory leak is occuring due to the recursion- but I have no idea why that would happen. Is it possible that the second raycast is spawning inside an edge collider?

[stuck palm]

im not getting any errors, heres the system if thats any help

[wintry quarry]

this has nothing to do with your code. Those warnings are related to the job system/unmanaged C++ side of things

just restart the editor

[desert elm]

oh okay-

good to know, thanks

[polar acorn]

Okay, so each instance of this script has its own particle system as well on the same object

[stuck palm]

correct, this is the prefab

[polar acorn]

And the particles are set to play on Awake, so what happens if you just disable this script entirely? Are the particles constantly playing?

[stuck palm]

doesnt seem like it actually, thats weird

[polar acorn]

So then it seems like either:
A) Your particles are playing and you don't realize it
B) Some other script is stopping them

If you select the particle system there should be a little preview window. Do you see them in that

[stuck palm]

its selected, cant see anything

[polar acorn]

Click that play button in the corner

[stuck palm]

it starts playing

[polar acorn]

Okay, so it is visible in the scene when playing

Here's an idea, comment out the line that stops the particles, and add this in update:

if (!fast.isPlaying){
  Debug.Log($"{gameObject.name}'s particles are stopped!", this);
}

If this logs, then a different script is stopping the particles.

[polar acorn]

Well, it's not stopping but isn't that white swoosh the particle you're looking for?

[stuck palm]

no its meant to be these cascading circles

thats just a trail

[polar acorn]

Okay, so, since that debug isn't firing, then the particle system is playing. Select it in the hierarchy and see where the object actually is

[polar acorn]

I don't see the transform gizmo for this, is it where you expect it should be?

[stuck palm]

its because the particles are emitting from a single point, it is where its meant to be

[polar acorn]

That's what I'm trying to see. Is the Transform gizmo at the point you expect it to be

[stuck palm]

if i increase edge size it is there

[polar acorn]

Well, it seems to be playing constantly, nothing is stopping it, so my guess is it's just not visible from wherever you are looking at it

[stuck palm]

its just so weird because it does start playing and you can see it when there isnt any logic, i dont know what the hell is is happening 😭

[polar acorn]

So you can see it with the script disabled?

[stuck palm]

yeah like it is emitting

[polar acorn]

Then it's probably the changes you've made to the particle behavior in code

The angles and whatnot

[stuck palm]

lemme comment those out one sec

[polar acorn]

Try commenting those out for now and just play/pause based on velocity

[stuck palm]

it only seems to start playing once it reaches around 10 for some reason

[polar acorn]

Well, that's the speed you told it to play at, right?

[stuck palm]

i wanted it to play when it was greater than 10

[desert elm]

how do I make the scene show all layers?

[polar acorn]

Scenes don't "show" anything

They're collections of objects

[desert elm]

well, this part of the UI
I can only see the gameobjects with the default layer

[polar acorn]

Is that object on a canvas

Also, if you can only see things on default that's a camera issue

The camera has a culling mask

[desert elm]

in the game window its fine

[polar acorn]

So, I'm going to guess this is a misunderstanding of how canvases work. Are any of these objects UI objects?

Which ones are UI and which ones are non-UI?

[desert elm]

None of them are UI
I just want to utilize layermasks for raycasts

[sage mirage]

Hey, guys! I have a question. Where we use BoxCollider2D and where the BoxCollider?

[polar acorn]

Show a full Unity window screenshot, with one of those white circles selected and its inspector visible

[polar acorn]

Are you using 2D or 3D physics

[sage mirage]

Why I am asking that because something happening when I am using BoxCollider2D on my 2D game and the player just falling down???

[desert elm]

disable gravity

[sage mirage]

Oh, ok!

Thanks!

[polar acorn]

Hover over that box and double-press "F" on the keyboard

[desert elm]

in the rigid body

[sage mirage]

@polar acorn There is no problem to use BoxCollider on my 2D game right if I dont want to use the BoxCollider2D right?

[desert elm]

I've heard that 3D and 2D physics, which includes colliders, don't mix well

[polar acorn]

Are you using 2D or 3D physics

That is the only question

[sage mirage]

I don't know XD

[polar acorn]

if you're using 2D physics, BoxCollider2D

Otherwise, BoxCollider

You will never use both

[sage mirage]

How to understand which physics I am using ?

[polar acorn]

Is your game 2D or 3D

[sage mirage]

It is a 2D then I am using 2D right?

[polar acorn]

That would indeed make the most sense

[stuck palm]

i think im just gonna forget about this stupid particle thing

[polar acorn]

Can you show the inspector of this object's parent?

[sage mirage]

Yes, I just got confused when you said which I am using you know.

[polar acorn]

So, both of these have sprite renderers. A square and a circle. Did you want there to be two sprites?

[desert elm]

yes

this is how I want it to look, but I need to change the layers of all the gameobjects to default

[sage mirage]

@polar acorn Hey! The same happening with Rigidbody?

Rigidbody2D doesn't have gravity option btw

[polar acorn]

Ah, okay, I had to poke around the editor a bit to find it, click this box in the top right

[sage mirage]

Like to enable and disable

[polar acorn]

Again, are you using 2D or 3D

that is the only question

[desert elm]

oh yeah I see it

[polar acorn]

use the one for whichever one your project is

[desert elm]

its the eyes

thanks

[sage mirage]

@polar acorn You said before to enable and disable gravity. In 2D environment a Rigidbody2D doesn't have that option to enable and disable that's what I mean. So, how can I enable and disable any gravity? Do I have to use maybe the Rigidbody itself and not the 2D one?

[polar acorn]

I didn't say to enable or disable gravity

[queen adder]

You would just set gravity scale to 0

[polar acorn]

If you want your guy not to fall over, lock the rotation

[sage mirage]

HERE

Oh it was the other guy

[polar acorn]

Yeah that wasn't me

[sage mirage]

Sorry XD

@desert elm Why you said to disable gravity if there is no option for that in Rigidbody2D? Maybe you meant to use Rigidbody and not the 2D one like I said?

[desert elm]

there is?
just set gravity scale to 0

[sage mirage]

Oh, you meant in code alright

[sage mirage]

Thanks!

hello guys, im using the unity free assets third person controller on android. but the ui controllelr camera movement is way too fast. how can i slow it down ?

[tacit birch]

This is driving me crazy and I don't know how to fix this.
I have my Player set up using Spine and I've set up the SortingLayers correctly and everything. For some reason though when I MOVE the character slightly, the Children GameObjects that have SkeletonData seemingly duplicates the Player's Head sprite, causing it to overlap the eyes/hair/hat

It only seems to be happening whenever the animation is set, which is why i crossed out the line for the Start method (I accidentally had Head Untoggled in the video but you get the idea)
What am I doing wrong here?
