huh

[polar acorn]

Make a vector that is your horizontal movement.
Make another vector that is your vertical movement.
Add them both together to make your final movement vector.
Pass that value, multiplied by deltaTime, to controller.Move

One of two things is happening then:
A) Something else is setting the values back to white
B) The objects you're looking at in the inspector and the ones getting logged are not the same object.

Are you maybe changing the color of a prefab rather than the ones in the scene?

[elfin isle]

your losing me

[honest haven]

that function changes the color of the icon(button) but wont for the child

[polar acorn]

1. Make a vector that is your horizontal movement multiplied by speed
2. Make a vector that is your vertical movement
3. Make a vector that is (1) + (2)
4. Call controller.Move with (3) times deltaTime

[polar acorn]

So is the text you're trying to change the color of the one in the scene, or is it on a prefab?

[honest haven]

it is a prefab ddol

but yes it changes to blue and so should the text

[polar acorn]

Easy way to test, put this line at the end of the coloring section:

Destroy(windowText.gameObject)

If the text still exists, then you're recoloring the wrong object

[elfin isle]

im still lost but is this what you wanted?

[polar acorn]

In this case, since it is a 3D project "Horizontal" meaning XZ, and "Vertical" meaning Y

[honest haven]

awesome i changed the text name then debug it it is indeed the wrong child

thanks

[elfin isle]

what??

"Vertical" = W + S
"Horizontal" = A + D
im so confused

[polar acorn]

Horizontal movement: On the ground
Vertical movement: Up and down

You know

like what you were already doing

Just all in one line so your math was a train wreck

[elfin isle]

im completely lost

what are you talking about

[polar acorn]

I am talking about basic addition

[elfin isle]

no not that

[polar acorn]

You have your horizontal movement (in two dimensions because you're on a plane) that is controlled by your horizontal and vertical inputs. You want this value, multiplied by speed.

You have your vertical movement, which is gravity and jumping. You do not want this multiplied by speed

So make two variables

[elfin isle]

what

[polar acorn]

I literally cannot explain this any simpler

You were literally already doing this

[elfin isle]

no your

omfg

vertical

here is a and d

[polar acorn]

Here, you're doing horizontal and vertical in the same line. Then multiplying it all by speed and deltaTime

[elfin isle]

Z = Vertical
X = Horizontal

[polar acorn]

Z and X = Horizontal
Y = Vertical

I'm not talking about inputs

I'm talking about world space movement

[elfin isle]

your not??

[polar acorn]

I've explained exactly what I mean by "Horizontal" like ten different ways

Please read them

Feel free to scroll up I'm not elaborating again

Get your sidey-widey movement in one vector.
Get your jumpy-fally movement in another vector.
Add them

is that better?

[elfin isle]

oh my god you dont have to be an asshole about it

i thought you were talking about inputs not world space

[polar acorn]

I explained exactly what I meant several times

[tacit vigil]

Hello, I currently have the following

if(Physics.Raycast(ray.transform.position,ray.transform.forward, out hit,Mathf.Infinity,layerMask)){
      hit.collider.gameObject.Face=1;
}

Face is defined in a script of the prefab numFace with a getter/setter

I can guarantee that the raycast will always hit a numFace object, how can I cast the collided gameObject to numFace so Face can be set

[polar acorn]

GetComponent

[eternal needle]

you dont cast, Face is not a GameObject. it's (hopefully) a monobehaviour, so you would GetComponent<Face>

and setting it equal to 1 would also make no sense

[polar acorn]

You can't cast GameObject to a component, components are not extensions of GameObject, just a type of class that goes on them

[elfin isle]

still no need to be an asshole

[polar acorn]

And no need for you to just ignore everything I was saying to answer your questions

[tacit vigil]

ah, ty! I'm so used to standard OOP, i thought monos just like. assimilated into the object or smth. ty for clearing that up

[elfin isle]

fym ignore i was reading it i just thought you meant something else by vertical and horizontal what??

[eternal needle]

this is still OOP, gameobjects just have a list of components. its composition

[polar acorn]

Basically, GameObject has a component. A cast would imply a GameObject is a component. In this case, no avoiding the GetComponent call, even if you're certain it's only the one kind of object that'll get hit, you'll need that extra step.

GetComponent calls should be avoided when possible, but situations like this fall into the "not possible" category

[elfin isle]

this sounds like exactly what i had before that wasn't working

[polar acorn]

1. Make a vector that is your horizontal movement multiplied by speed
2. Make a vector that is your vertical movement
3. Make a vector that is (1) + (2)
4. Call controller.Move with (3) times deltaTime

You're missing steps 3 and 4. this results in Time.deltaTime only multiplying with the vertical movement

You'll want to actually store the result of (1) plus (2), so you can multiply that result by deltaTime

Vector3 is a struct, it doesn't produce any more garbage making a variable of type Vector3 than it does doing the math all in place, so you don't need to cram it all into one line

[elfin isle]

like this?

[polar acorn]

Yes, that should fix your issues with the horizontal being too high (now it's getting scaled by deltaTime). You might also need to modify whatever value you have for y since it's smaller than it was before

[slender nymph]

you should also do the speed multiplication separately so that you can normalize horizontal before multiplying by speed (or at least clamp its magnitude) so you diagonal movement isn't faster than other horizontal movement

[elfin isle]

speed is still effecting my y value for some reason

[toxic frigate]

hello all, does anyone know why my reload code isnt working? it keeps on firing even when its supposedly reloading

void Update()
    {
        if (target != null)
        {
            // Calculate the predicted target position accounting for gravity.
            CalculatePredictedTargetPosition();

            // Rotate turret to aim at the predicted position.
            CalculateRotationToAimPosition();

            // Fire if turret is aimed and not reloading.
            if (!isReloading && Time.time >= nextFireTime && IsAimedAtTarget())
            {
                if (shellsFiredInCurrentMag >= magSize)
                {
                    StartCoroutine(Reload());
                }
                else
                {
                    Fire();
                    shellsFiredInCurrentMag++;
                    nextFireTime = Time.time + fireRate + UnityEngine.Random.Range(-0.1f, 0.5f);
                }
            }

            // If target is out of range, clear it.
            if (Vector3.Distance(transform.position, target.position) > maxRange)
            {
                target = null;
            }
        }
    }
IEnumerator Reload()
    {
        isReloading = true;
        yield return new WaitForSeconds(reloadTime);
        shellsFiredInCurrentMag = 0;
        currentFuzeTime = timeOfFlight + UnityEngine.Random.Range(0.25f, 0);
        nextFireTime = Time.time + fireRate;
        isReloading = false;
    }

[polar acorn]

What does the current form of the code look like

[polar acorn]

And where do you assign y

[elfin isle]

before update

[polar acorn]

Show where you set it

[polar acorn]

So, y is 0

meaning that absolutely no vertical movement is occurring

[elfin isle]

well yeah but then it changes later

[sour fulcrum]

also just mentioning that when you do wanna do GetComponent calls a nice safe clean way is to use the TryGetComponent function where instead of

MyMonoBehaviour inst = gameObject.GetComponent<MyMonoBehaviour>();
if (inst != null)
    //thing with inst

you can just do

if (gameObject.TryGetComponent(out MyMonoBehaviour inst))
    //thing with inst

[polar acorn]

So, you change y after you do the movement?

[honest haven]

https://paste.mod.gg/lxsopejqwxdh/0 so now the text will change but the icon color wont seems to have gone in reverse and the debug says its changed

i ran it through ai just incase but that cant work it out

[mystic ferry]

Should I
A) Have one script that a bunch of different objects refer to, to change X object in the UI
B) have every script reference the part of the UI they need to change themselves?

[elfin isle]

yuh

[sour fulcrum]

Have you used events / UnityEvents before?

[polar acorn]

If this is everywhere that y is modified, it is not affected by speed

[elfin isle]

well when i sprint it changes how fast i fall

should i like restart my unity or smth cause

[polar acorn]

What does "sprinting" entail

[elfin isle]

it is very messy

but all it does is change the speed

[slender nymph]

at this point you should share the entire class using a bin site so digi doesn't need to keep asking for more and more code as it is revealed that you are doing more and more that could be affecting your issue 👇 !code

Yes but nothing on my UI is necessarily ever going to be changed by more than one script so is it still worth it to still use it despite that?

[sour fulcrum]

i mean that's up to you but ideally imo UI stuff is the perfect use-case of events because in most cases your core logic shouldn't need to acknowledge any of the UI stuff exists

[elfin isle]

i restarted my u nity and it worked

what

[sour fulcrum]

your core logic stuff would just fire off relevant events when stuff changes and your UI Manager would listen and update based on those events

[polar acorn]

You probably didn't recompile after changing the file. It is usually automatic

But if it got stuck, it wouldn't recompile

[mystic ferry]

Ok thanks.

[sour fulcrum]

small example from a project to show what i mean but you probably get it
UIManager.cs

    private void Awake()
    {
        GameManager.OnActiveTurnMovementChanged.AddListener(RefreshMovementUI);
        GameManager.OnNewTurn.AddListener(RefreshTurnCount);
    }

    private void RefreshTurnCount()
    {
        turnCountText.SetText("TURN - #" + GameManager.Instance.TurnCount);

        if (newInput != GameInput.NONE)
            text = text.Colorize(Color.yellow);

        selectedInputText.SetText(text);
    }

[hidden fossil]

what happens after i installed .NET SDK?

[eternal needle]

Also this kinda depends on your use case. If you're talking about updating a health bar, only one script would be updating this UI health bar of course, but many other things might be interested in the health. In that case youd already probably have events setup.
In the case of pressing tab and opening up a menu, that would make sense if you wanna just do it directly

[slender nymph]

you need to restart your computer. then you have the .net sdk installed

also how are you still on this? it's been an entire day

[hidden fossil]

i think my vs code is now configured

[hidden fossil]

oh i went to sleep cuz it took too long to download

[slender nymph]

yes, now you can open up the other file you had and find all of the usages of that event you were having trouble with

[hidden fossil]

oh wait what the

now its fixed?

yea it fixed on its own

[slender nymph]

you likely changed something that you don't remember

[hidden fossil]

i just didnt save the work i did last night

[slender nymph]

right so you changed something, you forgot what it was that you changed, and now you've finally saved and compiled your code so that it updated in unity

[hidden fossil]

no i remembered i didnt save what i did last night

i did something last night that caused the issue so i just exited without saving and now its fixed

[slender nymph]

if what you had done that caused the issue wasn't saved, then the issue would not have appeared because that change would not have been compiled.

[tawny grove]

i feel like this is a really bad/inefficent way to detect the key being pressed and then detecting when it is released, but i couldnt find a way to do it with the input event systems. any suggestions?

[timber tide]

I wouldnt GetComponent like that and instead store the array/list by the type

[polar dust]

Getting inputs in FixedUpdate is a bad idea, there's a chance that when the user presses the key, that FixedUpdate won't actually call at that exact moment

[tawny grove]

oh thats a good idea

[tawny grove]

yeah that is what im thinking. My original plan was a input event that would detect when being pressed (works) and then sets it to false when stopped

but i couldnt figure out how to pass a bool through the event

[eternal needle]

That's only really for GetKeyDown or Up since those are for one frame.
Using fixed update here just makes no sense cause nothing physics related is happening here

[eternal needle]

You could use GetKeyDown and Up,which are only true for one frame

Which would have to be in update also

[polar dust]

Oh is that so? I assumed it was the case for all input methods

Makes sense though!

[tawny grove]

so like
update{
if(getKeyDown.S){do stuff}
else if (getKeyUp.S{do other stuff}
}?

[polar dust]

In my game, I do input in update to store a throttle/steer float, which then gets used in FixedUpdate to drive my vehicle

[eternal needle]

I mean it still kinda applies to GetKey but it's way more rare youd have an issue. Youd have to hold a key down for like 1 frame which isnt feasible without a tool like AHK

[eternal needle]

Yea pretty much
Excluding the obvious syntax errors

[polar dust]

It keeps a nice separation between what the player is doing and what the actual vehicle does

[tawny grove]

ty for the help

[timber tide]

One more thing. For the else statement, you could consider a flag to prevent each frame from iterating and setting everything to false, but this could be considered a micro-optimization if we're talking about a handful of iterations

if(Input.GetKey(KeyCode.S))
else if(!platformsAreFalse)```

I guess similarly for each frame for when you hold down the input assuming those platforms are only ever set true/false in these scripts. One benefit of the event driven input system is that you can just listen for the toggles.

[cosmic dagger]

Good call . . .

[patent hemlock]

My logic now works the way i want it to but is there any drawbacks to why I shouldn't use a IEnumerator Coroutine inside of another IEnumerator Coroutine?

[teal viper]

There aren't really any drawbacks, aside from maybe making the code less readable and more bug prone.

Depending on how you have it implemented

[tawny grove]

where should i ask questions about like scene vs play issues with lighting(?) maybe transparency?

[patent hemlock]

more or less I have it to keep track of a removed object that needs to be brought back during a while loop for tracking a durability counter. (Imagine Minecraft block break but the block comes back after X seconds)

[teal viper]

This is more about the purpose of the implementation, rather than implementation itself

[timber tide]

Coroutine sequencing is hard. Sometimes I do feel like I nest too much

[teal viper]

#archived-lighting #archived-urp #archived-hdrp #archived-shaders
If not sure which one, maybe start with providing some info in #💻┃unity-talk

[tawny grove]

ty

[timber tide]

Sometimes I feel like update would be better off as a coroutine by default ;p

[patent hemlock]

I for sure was confused when i put a while loop in update and my project broke XD

[teal viper]

Can't imagine how that would work 🤔

[timber tide]

Just being able to yield the update execution would be nice instead of creating the coroutine in start

not a big deal, but I don't see any disadvantages to giving more control of how you exit the update

[teal viper]

You can return from update if you need to exit it earlier.

[timber tide]

Yeah but for example you've some transitional controller where you're fading from one scene to another. You'll usually have the pause the execution of everything until it's complete, especially your primary event controller.

So I'll end up having this sequence of logic deeply nested on top of a single coroutine

[teal viper]

That's the way. State machines could help. Engines usually try to keep their default implementation as simple as possible. If every update on a MonoBehaviour was a coroutine, it would add a lot of overhead that is not even required in most cases.

Also by design an Update function/method is intended to be something that updates the object once per frame, ideally fast-fast. Making it a coroutine would basically break that assumption entirely.

[vague charm]

Good evening, I am trying to make the water tiles in the game speed up when the player touches them but they don't seem to be interacting with each other. I can make the player delete when the edges are touched but the water does not do a thing. When the player object speeds up thats me clicking the mouse. I added the composite collider 2d and the waterBoost script to it but nothing. What am I doing wrong? x_x

[north scroll]

Trying to reload a basic scene, how come the existing hierarchy components such as UI get deleted? The only thing that stays is the GameManager, which contains in its script DontDestroyOnLoad(), and I was trying to understand how scene transitioning works. Basically I have an int in my GameManager script that I wanted to see if I reload the scene, it would keep the number, but then everything gets deleted so the GameManager cant reference the UI text GO anymore

[vague charm]

Playercontroller script and waterboost script

[teal viper]

Scene reload means that the current scene is unloaded entirely(aside from ddol objects), then the target scene is loaded.

[north scroll]

ye my blind ass just noticed that the hierarchy after the reload gets a "Game" GO drop down that contains everything else. But then the GameManager loses the textmeshpro ref i dragged in its inspector. Im guessing im gonna have to dynamically assign these via script then ?

[teal viper]

Yes.
The game manager shouldn't hold and hard references to the scene objects that would be unloaded. It would make sense to have some non ddol managers that hold reference to objects in the scene. And the game manager can access them(for example via singletons or by having them register with the game manager).

[mystic ferry]

I just rewrote almost everything in my game to use scriptable objects for certain things and it's taken me all night so I hope it was worth it. 😭

[tawny grove]

why does unity hate it whenever i do anything with prefabs? i have to reload the project or itll just keep running the unity_self error whenever i make a new prefab(most the time)

[cosmic dagger]

That's great! They have their uses; they save on performance (memory) and are key for default data where multiple instances share the same . . .

I need help creating a EnemySpawner but this spawner is following the player with two points (minSpawn) (maxSpawn) that show the area around the player and it make a flat plane. But the issue I having right now is trying to figure out how to make that while also making sure they don't spawn to close to the player. So no matter where the player move it will spawn in this area

[timber tide]

Can make your life easier by just using a radius

[tawny grove]

is there a way i can find where this error is sourced to? it only happens sometimes, but happens immediately after running (the inconsistency is making it hard to find a source)

[timber tide]

Are you using any custom plugins

or making any editor tools

Try just giving Unity a reset, otherwise it's probably something related

[tawny grove]

uhh smooth pixel pixel is the only outside plugin

wdym editor tools?

ill give it a reset

[safe root]

Wasn't sure how that would work either

[timber tide]

the distance of an enemy to spawn would simply be the minRadius

well, between the min and max radius

[safe root]

But how would I make it inbetween?

[timber tide]

add the min and max to one of the random methods

along with a random direction

[safe root]

Could you give me a expample please?

[patent hemlock]

how many dumb questions are allowed in a day? I'm struggling to figure out a way to pass variables from an object to a main controller for all objects of that type. I don't know if i should do inheritance or polymorphism.
ex. Object Controller does thing based off of if it's interacting with Object1, Object2 or Object3.

[sour fulcrum]

Could you provide a bit more context? sounds abit more inheritence pilled but the passing of variables might need more elaboration

https://paste.ofcode.org/69RsHhy5Pw7YwK9TJbd9rQ Here is the controller script. What i want is to have the different trees have different treeDurability and treeRespawn based on which tree I am interacting with.

[sour fulcrum]

ah for this you would probably just have like a TreeBehaviour MonoBehaviour script that has those values

and have different prefabs for the different types

[graceful cradle]

following a flappy bird tut, but my "pipes" spawn too frequently or close together
is this a scaling issue? considering i stretched the image in unity to be more pipe-like... hlp..

[eternal needle]

A lot of this logic looks like it should be on the tree itself

[patent hemlock]

I have tried that but when the tree is not active the script stops and doesn't active it again (unless i'm doing something wrong.)

[keen dew]

Have you tried changing the "spawn rate" value in the pipe spawner?

[graceful cradle]

oh lol wait

[eternal needle]

That would be because you are disabling the whole object, coroutines wont run. You could just disable the visualizes and collider if you want, or run the coroutine on another object that doesnt get disabled

[graceful cradle]

How to Design a Flexible Skill System Like League of Legends or Turn-Based Gacha Games Without Thousands of Classes?

[patent hemlock]

I do appreciate your input. I'm just trying to decide what is best for the project as a whole. i know this is a simple one just for practicing some theories, but i also want to think about it if I did scale it up. I'm still very new to coding and making different scripts and objects not just work together but also efficiently.

[eternal needle]

scaling it up isnt really an issue here, but i get what you mean. there is just not that many solutions here without adding more complexity. I think the simplest solution would be disabling visuals and the collider. Another thing you could do is have some sort of respawn manager in each scene as its own object. instead of an object trying to reenable itself, you could tell the respawn manager "activate me in 5 seconds".

[eternal needle]

dont have thousands of skills then if you dont want thousands of classes. its pretty likely your skills will require unique functionality, there isnt a way around having to declare what that functionality is if you want it in your game

[patent hemlock]

So after messing around a bit I figured it out! 😄 Just needed a main tree class that the controller referenced and then each type of tree child class just input their variable into that main tree class.

[eternal needle]

well glad it works 👍

[ripe galleon]

hi, i´m trying since 1 hour+ to find how to add/activate/diasctivate force on collision with a specific object only with visual scripting, could someone help me?

[verbal dome]

We don't really do visual scripting here, these channels are for C#. See #763499475641172029 or learn C# from the pins of this channel

[ripe galleon]

i fixed it lol

why is it impulse tho

instead of force in the rigidbody 2d add force

[verbal dome]

Impulse is used for one-shot forces, Force is used for continuous forces that are applied every physics frame

For example impulse = jump, force = walking

[ripe galleon]

that´s what i actually wanted to do that it becomes faster and faster but it didn´t work

[verbal dome]

If adding force continuously doesn't accelerate you infinitely, you have drag (linear damping) or friction slowing it down

[naive pawn]

force is in mass * acceleration (aka mass * velocity / time)
impulse, aka momentum, is in mass * velocity

[ripe galleon]

thanks, i will see : )

okay great

.net isn't backwards compatible afaik, but unity has been using 2.1 for a while so there shouldn't be any problems

okay

                {

        }
    }
}

I've put the destination game object in the right spot in the editor, am I missing something stupid that's stopping this from working?

the console is showing both print statements properly, it's definitely seeing the player touch the portal object

[keen dew]

Does the player use the character controller?

[vestal bobcat]

Yeah I'm using Unity's starter third person character controller

[keen dew]

If that's the standard character controller then you have to disable it before teleporting the player and re-enable after because the CC tracks its own position separately

[vestal bobcat]

Interesting, so the character controller is already controlling the player location and is overriding the portal, if I understand you correctly?

[keen dew]

right

[naive pawn]

not exactly "override", more like "conflict"
it can lead to unexpected behavior, not just "no effect" if it were overriding

[vestal bobcat]

Okay cool, so can I just put in public gameobject for it and reference it, then disable>move player>enable?

I'm not at the computer now, walking the dog, didn't expect an answer so quick haha

[wintry quarry]

public CharacterController

Not GameObject

[vestal bobcat]

Gotcha, thank you

[polar acorn]

You can also call Physics.SyncTransforms() after doing the teleport instead of enabling/disabling the CC, but that'll recompute every rigidbody and CC in the scene and depending on how many you have and how often you teleport it, you might still want to do the enable/disable thing

[raw smelt]

if u use PhysicalVelocity
I should do it
physicsVelocity.Linear = moveData.speed * direction*deltaTime;
or
physicsVelocity.Linear = moveData.speed

[wintry quarry]

you don't multiply deltaTime into your velocity, no

that happens automatically inside the physics simulation when it decides how much to move the object each frame

[thorn holly]

Wait is the same true from AddForce?

[wintry quarry]

correct, never use deltaTime in AddForce

[thorn holly]

Whoops

I better fix that

[cosmic dagger]

Yes, if used in FixedUpdate, don't use deltaTime with AddForce . . .

[thorn holly]

It’s in update…should I be using it in fixed update?

[cosmic dagger]

Yes, remove it from Update . . .

It's a physics method; it should be applied in the physics update, which is FixedUpdate . . .

[thorn holly]

Alr

I assumed I'd need to use GetComponent to grab it but it won't even let me past creating the variable

[cosmic dagger]

Do you have a type — in this case, a class — called CharacterController?

[wintry quarry]

did you make a CharacterController namespace somewhere in your code or is there one somewhere inn this Unity Template code?

Why is your code in this Unity.Template.CompetitiveActionMultiplayer namespace?

[vestal bobcat]

¯_(ツ)_/¯

I imported the multiplayer stuff to play with it and even after removing it because it wouldn't let me start in my own scene it left its stink all over my project. I guess I have to start over

I have this

[vestal bobcat]

Creating a new project and copying my scene and scripts seems to have worked, the player is teleported when touching the portal surface. However, now the camera isn't following the player.

oh the joys of learning

Okay I just deleted that unit.template.competitiveactionmultiplayer shit after recreating the entire project and it works now. Thanks for your help.

    [SerializeField] private bool _isBig = false;

    public Button closeButton;

For some reason I can't drag/drop the close button in the field and clicking the search icon yields no results.

[verbal dome]

You can't drag a scene reference into default references

It needs to be a prefab

What are you trying to do?

[wintry quarry]

^ This.
In general assets (things in the project window) cannot reference things in scenes (things in the hierarchy window)

[crystal bridge]

Yeah, I saw online that the script needed to be added to the button, but I have to adjust script because the button in-game is doing things that the other object is doing. I think I might know how to fix though.

[timber tide]

I never insert anything into those default reference windows if that means anything to you :p

[crystal bridge]

Ok, so I correctly assigned things and now my intentions are being met. I have an object (Let's call it A) that, when clicked on, it grows big AND a Dialogue box appears that contains a Close Button. When the Close Button is clicked, the box is destroyed and Object A shrinks back down to original size. This is all good.

The issue is that the Close Button itself is also growing when object A grows. I thought the Listener method was supposed to make it so the Button wouldn't do what Object A does, but 'listen' to what it is doing so the button knows what to do when to do it.

[cloud walrus]

Is this a bug in unity? I can't even get near of my object without seeing it disappearing

[rich adder]

select it and press F. Your camera near/far clip is set to something else

btw not code related #💻┃unity-talk

[cloud walrus]

mb i just didn't know in which channel is should post it

[cloud walrus]

kk man thx i'll try this right away

[rich adder]

is close button child of the thing that expands ?

whats the purpose of the rectTransform thing in update?

btw you can just do rectTransform = (RectTransform) transform

no need for GetComponent

[wintry quarry]

Your code is doing transform.localScale = _bigScale; That means whatever object this script is attached to is going to be scaled.

[crystal bridge]

Object A and Button are not children of each other

[wintry quarry]

So if the script is on the button, it's the button that will scale

[rich adder]

^
if transform is the button then it will expand

[crystal bridge]

I get that, but how will I assign the button/script relation so that Object A shrink when button pressed? My original reference was when I tried to attached object to the script itself (which we covered you can't do). Currently it is attached to the field of script that is on Object A.

[rich adder]

the script is not in the scene?

why can't you do[SerializeField] private Transform objectA

[crystal bridge]

Well the script is assigned to Object A. I set up the script a bit ago to grow/shrink Object A and then been dealing with making the Dialogue box system. Today I'm trying to add this detail to the script.

Are you saying to create the field for objectA and attach it to the field while script is still on objectA?

[rich adder]

oh so this is on objectA?

[crystal bridge]

The script is. The Dialogue box hierarchy which contains the button is on the same canvas, but not a parent/child with object A

[rich adder]

so the close button a separate thing and NOT child of ObjectA that resizes?

[crystal bridge]

Correct

ObjectA has no children at all

[rich adder]

closeButton has any scripts on it ?

[crystal bridge]

no

[rich adder]

could you show the hierarchy for the ObjectA that has script

[crystal bridge]

Photo is objectA

The Dialogue script does have a field for the DialogueBox, but that shouldn't change parent/child relations, right?

[rich adder]

what does Dialogue script do

[crystal bridge]

It exchanges the respective objects/texts with the customized options set for each ```cs

object.using UnityEngine;
using UnityEngine.EventSystems;

public class Dialogue : MonoBehaviour, IPointerClickHandler, IBeginDragHandler
{
public GameObject dialogueBox;
public string dialogueText;
public Texture[] portraitTextures;

public void OnPointerClick(PointerEventData eventData)
{

    SwitchTextAndPics();
}

public void OnBeginDrag(PointerEventData eventData)
{
    SwitchTextAndPics();
}

public void SwitchTextAndPics()
{
    dialogueBox.SetActive(true);

    if (DialogueManager.Instance != null)
    {
        DialogueManager.Instance.DisplayDialogue(dialogueText, portraitTextures);
    }
    else
    {
        Debug.LogError("DialogueManager.Instance is null");
    }
}

}

[rich adder]

yeah doesn't seem to be touching the hierarchy but I have no clue what DisplayDialogue is doing

[crystal bridge]

Small note is that ObjectA's script (ClickToBig) does include SetAsLastSibling in the Update to ensure that when it grows, it covers all other objects

[rich adder]

yeah but is it putting it After RhiaDialougeBox or inside of it ?

[crystal bridge]

When playing the game, I confirm that the Photo moves at the very bottom after RhiaDialogueBox

[rich adder]

yeah that shouldn't affect Close Button scale then

btw colliders should not be used / needed on canvas objects

[crystal bridge]

I thought that was required for OnPointerClick and DragEvents

[rich adder]

OnPointerClick uses the Rect Transforms / event system raycast
(you can however use Physics Raycaster for colliders on non-ui objects, but thats another topic)

OnMouseDown is what uses colliders

[cerulean hamlet]

Hello! I'm wrangling unsuccessfully with Unity's runner template. Something in Spawnable is resetting the positions. I disabled snap to grid and added the m_InitialPosition vector, but no luck!

https://paste.ofcode.org/DLfbkzT7N8iW5Bd2BGzPBj

[slender nymph]

only for world space objects (also the camera would need a physics raycaster), UI doesn't use colliders for any of that

[crystal bridge]

Is there a way to lock a value of a specific object (closeButton) in public update?

Or maybe even in Awake\

[rich adder]

wdym "lock a value"

[crystal bridge]

Value of trans dimensions

[wintry quarry]

If you don't want the value to change, don't change it

if you want that to happen conditionally, that's what if statements are for

[rich adder]

if something is changing its size probably want to get to the bottom of it, instead of forcing size with update

[rugged beacon]

why are unity event avoided? or at least all the guides i have seen using event use c# action delegate instead

[crystal bridge]

I know that, but the issue here is that the Close button needs to tell the object to shrink when clicked. It is doing that, but the button grows with the object.

[rocky canyon]

bandaid fix's dont last forever

[rich adder]

UnityEvent is very good if you need modular/ inspector. No other real benefits over Action otherwise

[wintry quarry]

Who avoids UnityEvent? They are widely used.

if you want to set up the listener in the inspector, that's the way to do it

[wintry quarry]

that doesn't sound related to this "locking" question at all

[rocky canyon]

set a flag..

[rugged beacon]

i though the same, found it through the code auto completion, but have seen 0 guides using unity events

[wintry quarry]

you are simply growing/shrinking the wrong object

[wintry quarry]

They are used all over the place. They are different tools with different purposes than C# events though. ¯_(ツ)_/¯

[rocky canyon]

if u ever used the actions on a button in the inspector you've used unity events

[rich adder]

[SerializeField] UnityEvent somethingToDo// or make it public if you want other scripts to reference this

void Foo(){
somethingToDo?.Invoke()

[rocky canyon]

someone fact check me.. are those unity events or regular events?

[slender nymph]

those are unity events, UnityEvents are serializable unlike regular c# delegates

[rocky canyon]

ahh, thast a good way to tell

thanks 💪 🦅

[rich adder]

I think the more "useless" ones are UnityAction

[slender nymph]

one drawback of a UnityEvent though is that anything with a reference can invoke it unlike a delegate with the event modifier which prevents other objects from invoking it

[rocky canyon]

i have a shrink/grow menu system if it ever loads up

[slender nymph]

those aren't really useless, it's the delegate that UnityEvent uses

[rich adder]

Ohh okay makes sense.. so they are not just a Unity version of Action

[rocky canyon]

||redacted||

[slender nymph]

nah, they are just a delegate just like System.Action

[rich adder]

||CIA jfk files||

[slender nymph]

the name does kind of make it seem like something special though

[rich adder]

Unity prefix makes it sound important lol

[rocky canyon]

lol.. same w/ my project..

if u remove SPWN namespace nothings gonna work 😈

[rich adder]

assembly def is next

[cerulean hamlet]

Could someone take a quick look at this with me?

[rocky canyon]

👀

what we lookin for

[rich adder]

another overconvoluted Unity Template

[cerulean hamlet]

Mmmhm

[rocky canyon]

eww

[cerulean hamlet]

[ExecuteinEditMode] seems pretty risky just from the look of it

I don't know why they did that

[rich adder]

ikr ? my first learning experience in unity was the FPS-MicroGame

it was not good to learn on

[rocky canyon]

eww no kidden

beginners need bite-sized chunks

not the entire pizzeria

[rich adder]

fr

too many abstractions too

[cerulean hamlet]

My gamedev class tossed this into our laps :d

[rocky canyon]

teachers suck

"you try it"

[rich adder]

most teachers are failed in the industry for a reason

[rocky canyon]

teachers look for initiative or should...

i'd go off the beaten path myself

lol

[cerulean hamlet]

I'm on exchange in Ireland for the semester -- having a very different CS experience, course is entirely self-guided and has no AI restrictions. His premise is, just get it done, which doesn't feel conducive to learning imo

[rich adder]

not at all.

Unity has actual pathways that teach you from 0

these "templates" are meant to be "plug n play" if you feel like going through hours of someone elses thoughts and try to understand why certain things are coded a certain way

[rocky canyon]

unity killed my ram

[cerulean hamlet]

😭

[rich adder]

idk you'd have to check all the abstractions there, like m_LevelDefinition and other externally defined items

[frank flare]

is it possible to initialize it with a custom value?

[slender nymph]

just = desired value; after the }
https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties#automatically-implemented-properties

[frank flare]

ok

[sharp bloom]

Any ideas how should I point a projectile weapon directly to center of the screen/crosshairs?

Only things I found was for hitscan weapons

[verbal dome]

Well, you'd need to raycast from the center of the screen and make it look at that point

But that would be quite jarring

[sharp bloom]

For now I just simply give the arrow an impulse force forward

[verbal dome]

So you are talking about rotating the projectile, not the weapon?

A lot of games actually shoot the projectile from the center of the screen.
You can however have a fake visual object for the projectile that originates from the weapon instead

[sharp bloom]

The projectile is affected by gravity of course but I don't know how to make the aim satisfying

Like Hanzo from Overwatch

[verbal dome]

Do you mean, when hip firing/not aiming?

[polar acorn]

When it comes to replicating features, you need to really break down what makes up those things. You can't just say "Like hanzo", you need to actually assess what makes it "Hanzo-like"

That way you know what you actually want to achieve, and can explain it to people who have good taste in video games and therefore have no idea what that means

[verbal dome]

I really have a pet peeve for when people reference other games but don't even provide a link to said game feature

A video or something

Can't expect everyone to know every game

[sharp bloom]

I explained it badly

What I struggle with is finding the correct rotation for the bow such that the crosshair can be used to aim and lead properly

[verbal dome]

Since the projectile has gravity, the crosshair can't really tell exactly where it will land

[sharp bloom]

Because the arrow is actually physically fired from the bow's position

[verbal dome]

Unless you simulate its trajectory but that would be weird probably

[sharp bloom]

Eventually the player would of course figure out the correct way to aim with some trial and error

I have set the forces to be realistic for a crossbow bolt

[rare basin]

i guess everyone who atleast licked gamedev, or is playing games know who Hanzo is, from Overwatch

[verbal dome]

You guess wrong

Even if I know the character I don't know how the bow shooting looks in game

[polar acorn]

I think you overestimate how big of a property Overwatch is

[verbal dome]

So I'd have to go through the trouble of googling it/looking it up on youtube

[sharp bloom]

Yea I just said the first bow aiming game that came to mind, will need to research more of them

[frosty hound]

The issue with not firing directly from the center of the screen is that where the cursor is pointing doesn't let the player know where the projectile will hit, since the distance of the raycast will be different based on how far the thing that you're looking at it.

It's the reason why in games like Marvel Rivals, you have to always aim a little to the right to hit things, because the characters stand a little offset and "shoot" from their model positions.

[twin bolt]

Hello, i keep getting this error, from a custom render feature when i try to build my game that says

Did you #if UNITY_EDITOR a section of your serialized properties in any of your scripts?```
 It points towards this script https://hastebin.com/share/gajokizoqi.csharp , and i've tried alot to fix it and nothing works. Does anyone know anything about this?

[crystal bridge]

Looking for Recommendation:

I have a DragDrop script that works great for standard objects. I have other objects which will need to be Dragged&Dropped as well, but the image that you see before clicking will substitute the image.

Looking for insight if I should modify the script I have to apply to both or should I make a different DragDrop script (diff name of course) to use for the image switching methods?

[edgy prism]

Hello, Im trying to have a gameObject bounce off my SolidObjects tilemap I have some code that is somewhat working however I dont think it is detecting hits fast enough. I have tried using OnTriggerEnter2D and OnCollisionEnter2D but neither detect anything, there's gotta be a better way so any advice is appreciated.

void FixedUpdate()
    {
        RaycastHit2D hit = Physics2D.Raycast(transform.position, Vector2.down, 1f, tilemapLayer);
        if (hit.collider != null)
        {
            if (hit.collider.gameObject.name == "SolidObjects")
                ReverseVelocity();
        }
    }

[wintry quarry]

Wdym by "not detecting hits fast enough"?

[edgy prism]

So, It collides with my solid objects and actually reverses the velocity maybe half the time, I am assuming here that my raycast combined with the objects movement are causing it to miss hits

[wintry quarry]

well I wonder why you are doing the raycast in a fixed direciton (down) at a fixed distance (1)?

Shouldn't you use the object's actual velocity here?

[edgy prism]

Ahh yes I probably should be doing that, would that help with always detecting the solid objects tilemap?

[copper wind]

I don’t have a full picture of what you are trying to do, does it only collide on the bottom of the object? Or can it collide and reverse directions on like a wall or ceiling as well? Maybe try physics.OverlapSphere if you need to test all directions

[edgy prism]

Yeah so it’s pretty much just a projectile that’s supposed to collide with a big square and bounce around on the inside you’re probably right a sphere is better it was just something I threw together quickly cause I didn’t think I’d end up using raycasts

[copper wind]

Well so if it is always raycasting down, it’s not gonna work on the sides and ceiling right? So you could use overlap sphere, or like the other person said have the raycast be in the direction of current movement. But raycast based on velocity direction might not work if like the projectile makes contact on its side / edge. Why aren’t you just using like a standard collider detection?

[edgy prism]

I’m unsure what you mean by standard collider detection

[copper wind]

Put colliders on both the projectile and the (sides of) the square

Then use onCollision

[edgy prism]

I have a tilemap collider and a composite collider on the tilemap, and a collider on the projectile of course but when I was using onCollision it wouldn’t register collisions with my tilemap

[rocky canyon]

you can be cheeky and right after u launch the projectile it can look towards where a raycast would hit from the camera thru the crosshair

[copper wind]

Can you send screenshots of the colliders on both the projectile and what the tile map with so I can see the settings

And also the on collision enter code

[edgy prism]

Sure thing

void OnCollisionEnter2D(Collision2D collision)
    {

        if (((1 << collision.gameObject.layer) & tilemapLayer) != 0)
        {
            ReverseVelocity();
        }
    }

[white lagoon]

my character seemingly doesn't want to get down to the floor, how do i edit the sprite so that the hitbox matches up better

[rich adder]

not a code question.
Try putting Pixel Perfect / Pixel mode in sprite editor

#🖼️┃2d-tools

[white lagoon]

okay it kinda is though

because it's the box collider on his feet that stops it

okay maybe still not but it's not related to the sprite

[rich adder]

where is the code part?

[rich adder]

you're the only one who mentioned sprite lol

" how do i edit the sprite so that the hitbox matches up better"

[white lagoon]

so how do i make it so the extra box collider doesnt affect the height of the object

[rich adder]

make it a child(actually this one doesn't work if parent has rb) or trigger

[white lagoon]

okay thank you

[dense wind]

a box collider isn't code

[white lagoon]

one more issue, as u can see the collider is literally in the ground which has the "Ground" tag but the code doesn't activate (it's actiavted when i press w and it doesn't do anything)

[dense wind]

what the heck

[white lagoon]

yes that is a foot collider called groudon

[dense wind]

this code is so cursed im sorry

[white lagoon]

expected that

[rich adder]

what is calling groundCheck() and why did you nest function in there

[wintry quarry]

Why are you apparently manually calling a function called onCollisionEnter2D?

[rich adder]

and this ^

[white lagoon]

cuz i dont know how to do it correctly

[wintry quarry]

Also why is it a local function inside .. .yeah lmao

[copper wind]

sorry went afk. Which one is your projectile? it looks like you have a rigidbody on your tilemap gameobject? The projectile needs both a collider and a rigidbody, whereas the thing that is being hit (tilemap) does not need a rigidbody

[white lagoon]

this is code beginner isnt it

[wintry quarry]

Looking at the code examples in the docs would be a good start https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html

OnCollisionEnter2D should be its own separate function, not inside another one, and you don't call it yourself

[copper wind]

also add a Debug statement in the first line of the OnCollisionEnter2D just to see if it is colliding but the layer mask it setup wrong

[dense wind]

-OnCollisionEnter2D is a message sent to scripts, and it takes a Collision2D as an argument

• uppercase methods
• why are you nesting functions for no reason

[white lagoon]

well unity said that OnCollisionEnter2D isn't called

[rich adder]

would be best not to nest functions like that.
"Declaring a function body inside another function makes it a "localFunction"

[rich adder]

yes because you nested it inside another function therefore cannot be called by the normal Monobehavior way

[dense wind]

isn't called?

[wintry quarry]

Unity definitely didn't say that

Maybe your IDE said it

Unity didn't

and if your IDE said that it's most likely not set up properly

[white lagoon]

was as a warning in the console

[rich adder]

probably a UNITY IDE error

[wintry quarry]

you'd have to show the exact code and the warning that code created

but - basically you did something incorrectly

[dense wind]

I think some examples and tutorials would go a long way

it would be hard to explain everything you are doing wrong and why

[edgy prism]

Ah the second is my projectile which does have a rb but I forgot to include it and the rb on the tilemap is there because its required for a composite collider. Also tried adding a log to the collision enter and nothing at all

[dense wind]

you seem to just be winging it

[copper wind]

is the tilemap actually in the tilemap layer?

[white lagoon]

that was the idea indeed

[edgy prism]

Should be yeah

[copper wind]

double check lol
also if you set Collision Detection to continuous does that solve it? or is it already set

[dense wind]

when you're at this level you should be looking for "how to do X correctly" rather than "how to fix what I am doing wrong"

theres a million examples of how to do what you are doing out there

[edgy prism]

If by in the layer we're just talking about the layer set at the top of the inspector then it is just wasnt sure I fully understood. And yeah tried setting to continuous hasnt changed anything

[white lagoon]

tutorial hell

really quite contradictive the advice im getting everywhere

[dense wind]

whats the contradiction

[white lagoon]

people telling me to look at tutorials and other people telling me to not do that

[copper wind]

idk who is telling you not to look at tutorials that is just wrong

[dense wind]

idk whos telling you not to look at tutorials thats just dumb

no offense

[polar acorn]

The correct answer is look everywhere

[dense wind]

i dont really think anybody said that

[copper wind]

tutorials are great. relying on them later on isn't but in the beginning you should utilize them

[polar acorn]

You aren't going to find Tutorials that will do exactly what you want, and you should instead try to synthesize from multiple sources

[dense wind]

tutorials will teach you the intuition and skills for how stuff works

[polar acorn]

if it's a good one

Don't just look for "How to ___" and copy the code

[dense wind]

dont copy the code, look at the code and try to understand why it does what it says it does

[copper wind]

sorry without seeing the bigger picture im not able to be much help, this is a simple task so there is probably something glaring missing i can't see. The script that has the on collision code in it, it's attached to the projectile right lol?

[white lagoon]

what the fuckk

okay that is my fault nvm

[stiff mirage]

finally made it update a text ui when clicking a button, pretty sure im a pro developer now 😎

[dense wind]

dont use local functions

not until you know what you are doing

[polar acorn]

You got a function in your function

[rich adder]

note how it says "localFunction" because you nested it

[white lagoon]

note how i realised i did it wrong hence the text under...

[dense wind]

you probably didn't even realize you did use a local function becausr you haven't seen enough code examples to know how code usually works

which is why looking for snippets and tutorials online helps so much

it builds your intuition

[rich adder]

void Func1(){

//nested func
  void Func2(){

only Func1 would be able to call Func2

[white lagoon]

literally the snippet i was given by someone

okay nevermind im just tsupid

[edgy prism]

No worries, I've shown pretty much all the code related to it which is why I dont get whats not working here, yep the script is attached to the projectile itself

[dense wind]

but you haven't seen enough full scripts to know where that goes or what it does

[rich adder]

missing basics of c#

[edgy prism]

Do you have any idea what might be missing?

[white lagoon]

problem is im missing understanding of unity functions

[polar acorn]

No, this is a C# one, not a Unity one

[white lagoon]

collisions aren't native to C# afaik

[polar acorn]

But functions and where to put them are

Your issue here had absolutely nothing to do with collisions

[white lagoon]

ye im just misunderstanding if it's a function or not

[naive pawn]

unity functions are c# functions with specific signatures
you gotta understand c# functions before you can understand unity functions

[white lagoon]

like the problem here is why does the function call for 2 variables which arent separated by a comma ( i know it's a varaible being defined now)

[naive pawn]

[wintry quarry]

ok no

[rich adder]

those arent two

[wintry quarry]

go back to the very basics of C#

[slender nymph]

that's not two variables, that's a single parameter of type BoxCollider2D (which is wrong) and the parameter's name collision

[white lagoon]

did u read the whole sentence

[naive pawn]

i don't even understand your message

[rich adder]

thats the TYPE and its name, its 1 thing

[naive pawn]

if you know it's a variable being defined, then, why is that a problem
because.. that's not what's happening

[wintry quarry]

Variables in C# have a type and a name

[polar acorn]

Uh, it doesnt

[wintry quarry]

it's not Python

[polar acorn]

There's only one variable there

[naive pawn]

yes and it made me more confused

[eternal needle]

the sentence doesnt even make sense. you say in the same sentence that you understand its a variable being defined..

[white lagoon]

okay so i see 5 people in a row stop their brain functions the second they get to half of the sentence

[naive pawn]

because the 2 halves are directly conflicting

or do you mean the "problem" is in past tense

[white lagoon]

yes that is indeed what is implied by "now"

[eternal needle]

whats the point of even bringing up that example then lol

[polar acorn]

Or because they're different people typing at the same time and not a hive mind

[white lagoon]

because that was the reason for the problems before

[eternal needle]

thats not related to what your issue was above, which is a basics of c# issue

[naive pawn]

and nowhere is it implied in your first sentence. the entirety of your first sentence indicates that it's a current issue

so know that we have clarification of that non-issue, let's move on
do you have any other problems you were gonna ask about

[edgy prism]

Nothing summons people to the chat like a good old fashioned argument

[eternal needle]

avengers assembling everytime a beginner gets a little too confident

[naive pawn]

this would imply the opposite of what you assume it to mean

a hivemind would all reply the same... like yall did lmao

[polar acorn]

They ask a question, get one answer, edit the question saying solved and then yell at everyone for posting after they edited it

[naive pawn]

they didn't edit that message lmao

i don't see any of their messages edited

[white lagoon]

never have i clicked edit in this sever

[naive pawn]

im so confused by this entire interaction....

let's just start a new one

anyone got any questions to donate

[polar acorn]

Or adding a second message saying "solved" rather than an edit

[naive pawn]

ok, completely unrelated to the message actually in focus?

move on, buddy

[edgy prism]

If you're interested im still struggling with my problem

Im now trying to get the projectile to register a collision in OnCollisionEnter2D but for the life of me it would collide with my tilemap collider

[naive pawn]

detecting hits fast enough
can you elaborate on what you mean by this?
is it phasing through the tilemap or something?

for the collision message, do you have the requirements for that message to trigger?

oh wait there are messages after that, one sec

[edgy prism]

Theres kind of a lot haha I can try and summarise if its quicker, basically yeah half the time if im ray casting It phases through even when I changed the ray cast to use the rb physics

[naive pawn]

ok, so you don't seem to have a dynamic rigidbody on either object

[edgy prism]

Ah so, Dynamic on both and it registers it also just bounced my tilemap off into oblivion haha

[naive pawn]

you only need one dynamic rb
you can leave the one on the tilemap static if you want (not sure if you need it at all)

[slender nymph]

if they are using a composite collider for the tilemap (which ideally they would be) then they do need the rb for it, but yeah it should just be static. the actually moving object should have the dynamic rb

[edgy prism]

Ok so seems to actually be colliding now, I cant believe I missed that, I think I tried it by editing the prefab root in my scene then instnatiating a new one. im an idiot but thankyou so much

[naive pawn]

ah, composite collider requires it, right? i remember my own tilemap having that rb too, just don't remember why lol

for future reference @edgy prism https://unity.huh.how/physics-messages/collision-matrix-2d

[edgy prism]

Thanks this will come in so handy im sure of it

[naive pawn]

digiholic also has this version lol #💻┃code-beginner message
not sure if it's their own or from some other resource

[white lagoon]

why should isTrigger not be ticked

[polar acorn]

Because if it was you wouldn't get any OnCollision messages

You would get OnTrigger messages

[bold iron]

Hi, im having difficulties figuring interfaces. It seems like the 2 scripts wont link up

[wintry quarry]

1. Your IDE is not configured
2. The error is talking about a third script called Interactor which you haven't shown and which presumably doesn't exist

[polar acorn]

What is Interactor

[bold iron]

i was following a tutorial, ill try to rewrite some part thanks for the answer

[wintry quarry]

You skipped something

Presumably

Wherever they define Interactor

[bold iron]

ok ill rewatch the video

@wintry quarry @polar acorn thanks guys i was blindly following the tutorial and didnt realize it was referencing a script. I got it working

[torn night]

how to get good at coding

in unity

[rich adder]

learn, research, practice. repeat

[rich adder]

check pinned messgae for resources

[copper wind]

practice, but make sure what you are practicing is something you enjoy. If you are practicing boring things you will not only not have fun but not be motivated to learn as much as you would if you enjoyed it

[wintry quarry]

Go to school for it

[copper wind]

computer science =/= coding

if you want to code, you can learn that not with college. college cs is theory and math

[wintry quarry]

False

Source I got good at coding by going to school for computer science

[copper wind]

im literally doing my master's degree in CS right now

true

you learned to code while being at college for CS, separate things

[rich adder]

"AI" can code, learn to be a good engineer / programmer

[copper wind]

if you just want to code, not like advanced design, you can do that without college

[wintry quarry]

It's a good way, that's all I'm saying

[snow warren]

Hi

I have a question?

[rich adder]

there might be an answer

[teal viper]

Are you asking us whether you have a question?

[snow warren]

No lol

[teal viper]

punctuation

[snow warren]

I wanted to ask

Is there any server api that can be used to upload pictures on the server and can be downloaded as well
And do not charge that much

It is because i want my game players to upload pictures as pfps in game

[rich adder]

You can do this with many free tiers, including unity

[teal viper]

Google drive is free if that suits you😅

[snow warren]

lol
google drive is free i guess
But it is not a good solution

For a multiplayer game

[rich adder]

Unity has PlayerData storage you can store the binary data of image

or a blob bucket like AWS , Azure etc.

[teal viper]

Might want to research then. It's not like we have a text file with "the best free/cheap services for uploading pictures" on our desktop.

[snow warren]

the problem is charges

Plus unity api doesnt allow large file transfers more than few 100 kbs
Nor can we access large files from the server of another user

I tried Playfab but we cannot get the other player's pfp

I found Google Firebase as a good solution
But they charge a lot

[snow warren]

Both of them are hella expensive

[snow warren]

[rich adder]

all the ones mentioned have free tiers

if you're going over the limits you might want to better monetize your expenses if you plan such high traffic

[teal viper]

The cheapest would probably be to rent a server and host your own api

[sand mesa]

i accidentally created magnetism

[snow warren]

I plan nearly 10k traffic

[sand mesa]

and I dont know what to do

[rich adder]

Digital Ocean has very cheap VPS you can get as much storage you want and they start at 3$

those require you to setup your own APIs like ASP.net

[teal viper]

Congrats, you discovered Gravity!

[sand mesa]

thats the thing

gravity's at 0

[snow warren]

Hmmmm

I do not have a good spare pc that can handle requests remotely

Plus the country i live in is trash

i pay like 22$ for 15mbs internet speed

[teal viper]

Ah, right. Well, Is it your code then?

[sand mesa]

and it keeps gravitating to the colliders

[rich adder]

thats not what renting a server means

[snow warren]

that seems reasonable

let me google it up

[rich adder]

https://www.digitalocean.com/pricing/droplets#basic-droplets
Ionos is cheap too. These are cheap but come at the cost of having to setup your own APIs / infrastructures

[sand mesa]

heres a clearer example

this is within the same level as

a room where the rules are as follows

so wtf

oh

nvm

I found the rpbolem

there was a big ass box collider I forgot to reduce

[rich adder]

@snow warren If I were you I'd start with the smaller free tiers with already setup apis for this this way you can use their auth systems, then if you need to scale up go from there.
Its easy to overplan

[snow warren]

I will look up to it and see which one suits me best

[normal mango]

Hello! I've got a weird technical problem that I feel has a fairly simple solution that I'm just missing. I'm creating a system where players tab an object and the info of that object appears through the canvas, specifically the object's icon and the player's notes. However, I'm having issues where there are multiple objects on screen with the "infoTabActivate" script, and the inputted text isnt saving to the list. i have each object's method as an on-end-edit listener but the console always activates every script at once but still returns nothng. how can i fix this?
https://paste.mod.gg/egckemsxirdb/0

[slender nymph]

https://unity.huh.how/unity-events/dynamic-values

[normal mango]

ah that fixed it, tysm!

[normal mango]

i added text.text = playerNotes[index]; to the OnMouseDown() method to set the text to the pertaining object, but for some reason the text always stays the same regardless of the object

did i call it incorrectly?

each object has a specific index value set in inspector

[polar acorn]

Put a log in the function and see if it's ever getting called

[normal mango]

which function?

OnMouseDown? im certain it gets called cause the rest of the method works properly

[sour fulcrum]

I know without specifics a proper answer can’t be given but realistically is the cost of creating tuples something I’m ever going to be worried about? (In the context of scales not big enough to justify dots or anything).

Was playing around with how I want to implement certain things and was considering a dict with a tuple as a key. Probably not what i’ll end up doing but got me curious

[eternal needle]

if the tuple is the key, could you not just define a class representing everything you need? the only time ive seen tuples used and kinda justified is when you want to return multiple values that arent grouped together otherwise.

you could profile it but i have a feeling like you'll not see any difference, unless you get to a significant amount of elements, at which point any operation would be slow

[polar dust]

I like making tuples if I'm feeling lazy and want to group a few things together that will always need to be used at the same time later ln

[sour fulcrum]

Possibly but I’m trying to be super generic about it in hopes I can maybe integrate it into my little toolkit package that I use everywhere

[eternal needle]

how would using tuples there be more generic than a class?

you can accomplish the same things

[polar dust]

Any more than 3 values and it ends up being easier to make a struct instead, a tuple with 4+ items means theres room for improvement

[polar dust]

They're very quick to write in the moment

[eternal needle]

not necessarily a struct either

[polar dust]

If I need two values together, there's not much harm in putting them into a tuple

[eternal needle]

and that isnt more generic, nor is a 5 second difference in writing code a real consideration. the question was more of a hint to saying it being a tuple doesnt help

[polar dust]

They're pretty easy to improve later on, there isn't too much complication they bring that'd be difficult to refactor

[eternal needle]

if its written in thinking you'll refactor it later, just write it properly the first time! also this isnt really relevant to what they were actually asking

[sour fulcrum]

I might want a central static manager handling this rather than giving the relevant items all the sauce.

The tldr is I want basically a ScriptableStat’s system where eg. An Enemy has a list of ScriptableStat’s (lets say Health, Speed & Damage) and these scriptableobjects are used to retrieve the runtime editable value type value from this central manager by providing the scriptable stat and themselves.

I absolutely could store this kind of stuff on the scriptableobject but just considering potential routes to avoid storing runtime stuff on them if I can. And since I want this to be pretty generic and modular I don’t wanna burden the enemy class too much with all this

[polar dust]

I'm only saying that I like using them for an immediate result, the use case definitely favours a class or struct. Nothing wrong with a lazy solution!

I don't think that tuples have too much cost too them

[eternal needle]

and still, where does using a tuple make this more generic than just using a class?

[polar dust]

As far as I know, they're fairly light and cheap

[eternal needle]

also a note, ValueTuple is a struct. i honestly forget if ValueTuple or Tuple is used by default because I never use them. if you use value tuple, you should be aware of when to use structs as well because you really shouldnt need them often

https://learn.microsoft.com/en-us/dotnet/standard/design-guidelines/choosing-between-class-and-struct
given your use case, i assume itll be boxed often

[spiral dew]

I have a Unity project on GitHub using Git LFS.

After making some commits, I reached my storage quota.

What are my options to continue working on the project? Should I buy more storage, clean up old LFS files, or is there another solution?

Also, I'm working on this project with one other person—how does Git LFS work in a small team?

Do both of us need to set it up individually, and how does the storage limit apply to us?

[timber tide]

Can always just stick to placeholder assets then disperse the assets later to the one building the project in chunks

audio and textures usually the main culprit and easy enough to substitue till later

[umbral bough]

Hi, I am working on 2 projects that use the same asset that behaves differently(asset is made by me).
In both projects, I wanna extend the partial TrackAsset class.
I included the assemblyref and placed the thing in the correct namespace, however, in one project it works fine and in the other it doesn't.
I have very little experience w assembly def/ref so I would appreciate somebody helping me.

[umbral bough]

My advice, switch to gitlab if possible.
You get much more storage(10gb iirc) and a lot more bandwith.

[umbral bough]

please @ me if you are able to help

[umbral bough]

ok, asmref was working correctly but rider was dying and not getting updated or sm...

level manager script it handles the currency and lives https://paste.mod.gg/vjyaiytqzvxo/0

[slender nymph]

this object is DDOL which means it is going to stay alive when you switch scenes and keep its current values. Start is also only ever called once during an object's lifetime, so it will not be called on this object again after the first time

[hidden fossil]

oh who do i drag a ddol into a scene?

[slender nymph]

huh?

[hidden fossil]

how do make the levelmanager stay in the scene?

[neon forum]

I split an array and am iterating through it, but I cannot for the life of me figure out what this little trailing blank is at the end. Is it a whitespace? is it NULL? WHat is this?

[slender nymph]

don't make it DDOL if you don't want it in the DDOL scene. but it simply being in that scene isn't the issue, the issue is that you are expecting a new instance of that object or for it to call Start again, neither of which are possible due to your currnet code

[slender nymph]

are we supposed to just guess what the actual context is or . . .?

[hidden fossil]

oh is there like a duplicate of the levelmanager causing the levelmanager to stay in DDOL?

[slender nymph]

did you not read your own code or what?

[neon forum]

I used Json.Split('}') on a json string that I pulled from a json file that was created to hold an array of objects(the array was parsed through and each object serialized).
The Json split mostly worked, but to parse through the string[] created with Json.split I'm using a foreach loop, and I'm finding that there is just a blank(see image), and I don't know what character that is, if any.

[slender nymph]

are you printing an entire string? if so, maybe check if it is null and if not print its length. you haven't shown actual code so naturally i can only guess at what the issue is

[neon forum]

I'm printing each string in the string[] created from splitting one big string, but I'll go with your suggestion because I just want an easy fix

[slender nymph]

that's not going to "fix" whatever the issue is, it's just going to provide more context about what you are printing

[neon forum]

exactly, and then the easy fix will be checking if that string is that context, if so, continue;

[slender nymph]

why are you even parsing this json manually anyway? can you not create an object and just deserialize to that object

[neon forum]

Is that possible with a json list of the same object?

[outer coral]

Is there no way to pass bools by reference to a coroutine? or anything by reference for that matter

[neon forum]

What's really funny is that I finally got it to work, and now I'm most likely going to learn a more efficient, more reliable way to do this entire process

[slender nymph]

that depends, if the root of the json is the list then you need to make sure to use Json.NET or some other json library besides JsonUtility (which is the json serializer built right into unity)

[hidden fossil]

oh is causing the levelmanager to be on dont destroy on load?
private void Awake() {
if (main != null && main != this){
Destroy(gameObject);
}
else{
main = this;
DontDestroyOnLoad(gameObject);
}
}

[slender nymph]

coroutines cannot have ref parameters

[outer coral]

rats

[hidden fossil]

problem fixed 👍

levelmanager now in the scene no longer in DDOL

[slender nymph]

yes, but again, it simply being in that scene isn't the issue. it's the fact that you keep it alive and destroy any other instances then expect it to be a fresh instance.
so you probably don't want it to be DDOL, but you were focusing on the wrong aspect of it being DDOL

[neon forum]

I created the json by doing a foreach loop through a 2d array and serializing each object within. they are the same object. Would the 'root' of the json be a list of obejcts or is it different?

[slender nymph]

did you create the json manually too? why are you not just using a json library for this?

[slender nymph]

again, the issue is not that it wasn't in the scene, the issue is that you were keeping the same LevelManager around but expecting it to act like a new one when you restarted and also destroyed any new instances that were created by reloading that scene

[neon forum]

no I'm using json.serializeObject for the objects

and i couldnt' serialize an array of objects because it breaks

[slender nymph]

that is a limitation of JsonUtility, it does not support collections as the root object, but you can just put the array into some wrapper object and de/serialize that

[neon forum]

ah so that's what they meant, I put the basic object into a wrapper, not the array

woops.

Can we ask for help in here?

[cold mist]

[sullen dew]

I'm trying to make a score system and I'm not sure how to go about it.
(I am on Unity Editor with C#, and I'm basically a beginner)

More detail:
I'm making a game that has a similar foundation to Agario in the sense that you eat things and grow in score and size.

I need to make a score system where each food has its own different value, and when eaten, that value is added to a player's score.
What I would want to do is have each instantiated food prefab have a easily assignable score value, and this to be acessed in my food eat script.

I have this right now below where each food is automatically 1 and this is triggered on contact with the food. I want the "1" to be a variable that matches the collided food's value.
playerFoodScore = playerFoodScore + 1;

I want it to be
playerFoodScore = playerFoodScore + collidedFoodValue;

The "food" is 3 different prefabs that are randomly instantiated into the game.

I do not know how to assign this value to each different food prefab and have it detected when my player collides with it. If anyone is willing, could you help me walk me through figuring this out?

I can provide more detail or show more detail if needed. I don't think I'm allowed to ask people to join calls on this discord server is that correct? If we are allowed then I can do that gladly.

[eternal needle]

you should have a component on the food itself. this component will have a value saying its worth, when you collide with something, try getting the food component and then just read its value

[fading barn]

whats wrong with this code

[stiff ocean]

what are you trying to do

[fast relic]

is it not doing what you're intending it to

[fading barn]

no

[fast relic]

or are you just asking for tips on how to make it better

[fading barn]

i am trying to play walk animation while moving

it is not playing it

stuck on idle

so i asked whats wrong

[stiff ocean]

pretty sure PlayerBody.angularVelocity is the players rotational speed

and from the looks of it the player shouldn't be rotating

[sullen dew]

I got it working thank you

it was easier than I thought it would be I think I was just scratching my head too hard

[fading barn]

still, its an or so it should work

[fading barn]

what should i use for getting movement velocity

[stiff ocean]

Movement() is being called in Update() right

[fading barn]

yes

[stiff ocean]

linearVelocity i think but i use traditional character controllers

[stiff ocean]

i mean i'd just use Input.GetAxis("Vertical") instead of Input.GetAxis(InputAxis.Vertical) but if the character's moving that's not the problem

[fading barn]

the problem is with animations

here have a look

[rich adder]

InputAxis .Vertical is a const they've made

[stiff ocean]

i see

[fading barn]

its a var though

[stiff ocean]

i have never used that panel in my life 💀

[rich adder]

you mean a static variable ?

[fading barn]

i should change it to const cause it is constant

[fading barn]

you havent made a game with animations?

[rich adder]

so is that part of animator running

[fading barn]

am i doing something wrong

[fading barn]

it is stuck on idle man

[stiff ocean]

i've never reached the animation part

[rich adder]

stuck as in keeps playing or just doesn't go into other animation at all

[stiff ocean]

normally i save stuff like that for after the game's working

[fading barn]

doesnt go

idle has no animation btw

yet

[rich adder]

put debug.log first inside that if else statement

[fading barn]

ok

[rich adder]

what is the exit condition walk to idle

[fading barn]

shall i debug using visual studios debugger?

[rich adder]

if you want to put a breakpoint that works too

do you know how to set it up?

[stiff ocean]

btw nav do you know what's going on here?

mv is being set

[rich adder]

what is supposed to do ?

[fading barn]

its printing

on console

[rich adder]

which part of if statement

[stiff ocean]

you type your username into the text input field, then hit enter, and then it sets your username on the mv component and hides the UI element

which isn't happening at all

[fading barn]

have i set up animator the wrong way?

[rich adder]

submit button?

[fading barn]

its one giant if statement with bunch of conditions and an else so i dont know which part

[stiff ocean]

like have a UI element that submits instead of waiting for the submit key to be pressed?

[rich adder]

the part where you set animator bool to true

[rich adder]

GetButtonDown Submit ? are you pressing the keyboard button for "Submit"

[stiff ocean]

yes

[rich adder]

ok but please don't send ss of codes, use 👇

[stiff ocean]

(the chat script was firing)

[rich adder]

so text is not focus?

[stiff ocean]

text should be focussed (iirc IsFocused detects if im currently typing in it)

[rich adder]

breakpoint or Debug.Log(text.IsFocused). easy checks

[fading barn]

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    [SerializeField] private float speed = 100f;
    [SerializeField] Rigidbody PlayerBody;
    [SerializeField] Animator animator;

    void FixedUpdate()
    {
        Movement();
    }

    void Movement()
    {
        PlayerBody.AddForce(transform.up * -Input.GetAxis(InputAxis.Horizontal) * speed * Time.deltaTime);
        PlayerBody.AddForce(transform.right * -Input.GetAxis(InputAxis.Vertical) * speed * Time.deltaTime);

        if(Input.GetAxis(InputAxis.Vertical) < 0f || Input.GetAxis(InputAxis.Vertical) > 0f ||
            Input.GetAxis(InputAxis.Horizontal) < 0f || Input.GetAxis(InputAxis.Horizontal) > 0f ||
            PlayerBody.linearVelocity != Vector3.zero)
        {
            animator.SetBool("isWalking", true);
            Debug.Log("check animations");
        }

        else
        {
            animator.SetBool("isWalking", false);
        }
    }
}
class InputAxis

    public static string Horizontal = "Horizontal";
    public static string Vertical = "Vertical";
}

[rich adder]

so its printing yea?
are you holding down the keys the entire time?

[fading barn]

yes

[rich adder]

did you show the exit transition walk to idle

[stiff ocean]

yes it is, but it turns false the frame i hit enter

[fading barn]

wdym

maybe no\

[rich adder]

switch up the order of && condition or make a different one

[rich adder]

show that

[fading barn]

is it ok to set up animations in fixed update?

[rich adder]

I would use update but it should work

[rich adder]

this is idle to walk. what about other way

[stiff ocean]

invoking with 1s delay worked

[rich adder]

seem sketch

[stiff ocean]

ty

[rich adder]

btw you should remove * Time.deltaTime on rigidbody AddForce

thats not correct to do

[fading barn]

ok

[rich adder]

the animator instance has this controller and you referenced the correct one ?

[fading barn]

leme check

you know what

let me share the project with you

maybe you can see whats wrong

[rich adder]

screenshot should be fine if you show specific thing, there aren't many things that can be wrong

[fading barn]

should i add animator to armature(rig/bones) or mesh?

also my avatar field is empty

[rich adder]

if its humanoid and has an armature then it should probably have an avatar

without the animations, check if its actually going into the states which seems likely now and probably wrong setup of rig

[fading barn]

its a walking bulb

can you have a look at my project

i will share you

[rich adder]

I would check this first to eleminate the possbility that is code
#💻┃code-beginner message

have the object with that animator selected, drag the animator in a side by side tab game view

[fading barn]

my avatar is empty

[rich adder]

would still check the animator states

[fading barn]

its the animator controller

it is not playing animation even without conditions

why is this so confusing. isnt unity supposed to be easy

[naive pawn]

"easy" is relative. if it's hard with the given tools, imagine how hard it'd be without any help 🫠
if it's not a code issue, check out #🏃┃animation

[fading barn]

Unreal is easier to setup materials and lighting but runs crap on my laptop and Its way harder to learn

[fading barn]

It's an issue of setting up animations through code

[fading barn]

Internet is a blessing and curse.

[naive pawn]

do you mean like, animator parameters? or the actual animator states?

[fading barn]

Switching between animation states

Is what I meant

And it's done through code so I came here

[naive pawn]

directly or via parameters?

[hardy prairie]

Hi, anyone know to use visual script?

[fast relic]

probably people in the #763499475641172029 channel

[hardy prairie]

im getting lost every once

[west sonnet]

I'm following an FPS player controller tutorial using Unity's input system. In the tutorial, the person wrote 'e' in their code, but they don't really explain what it is. I've never seen it before. Does anyone know what it is?

I don't think 'e' is a reference to anything either

[fast relic]

it's called i think a lambda expression https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/lambda-expressions

You use a lambda expression to create an anonymous function. Use the lambda declaration operator => to separate the lambda's parameter list from its body.

[west sonnet]

Is that not the '=>' ?

[fast relic]

it is the =>

[west sonnet]

So that's the 'e'?

[fast relic]

and e is the parameter

[west sonnet]

Ooh okay

Man, Lambda is confusing

In the screenshot above, how does the 'e' know what it's referencing?

[fast relic]

because you're adding the method to the performed delegate (i think it's called delegate? not sure on that one) of the action, and it passes in only one argument

[west sonnet]

So would the 'e' reference any of these inputs (W,A,S,D)?

When any of them are pressed

[fast relic]

e references the CallbackContext, on which you can use the method ReadValue<Vector2>() to get a Vector2 containing the direction of the input

[west sonnet]

So when I press an input key, e read the Vector2 value which is applied to my input_movement value and then added onto the input character movement value?

[fast relic]

when you press an input key, it calls the lambda function which reads the value and sets input_Movement to it

[west sonnet]

Why is this += then? isn't that adding the input_Movement value back onto the defaultInput.Character.Movement.Performed value (if that's even possible?)?

[fast relic]

the performed value is a delegate, which is sort of like a set of methods that gets called whenever it's invoked, https://youtu.be/J01z1F-du-E?t=169 (timestamped)

[verbal dome]

+= means you subscribe to the action, so that every time the event on the left (...performed) is invoked, the lambda on the right will be invoked too

[fast relic]

it's not adding the value, it's adding the function

[brazen pagoda]

So the thing you most often see in C# is a method signature that helps describe the parameters tha a method will accept.

For delegates/events the signature is where the delegate is defined, not where you subscribe ( += ) or unsubscribe ( -= ) to it.

Here's the definition of the performed event:

Which shows that any callback that subscribes to this event will receive a CallbackContext. In this particular case a Lambda expression is used and the callback context received here is named e (left side of =>) by the lambda expression for the lambda expression to use in the code it executes (right side of =>)

[west sonnet]

Are lambda expressions used to avoid having to write out entire methods and to keep things compact?

[brazen pagoda]

Yes

In Java these constructs are known as "Anonymous functions" because they don't have a defined signature

The general idea is "this is the only place you will use this code, so let's skip the many lines of a method"

[west sonnet]

How are delegates/events different from methods?

[brazen pagoda]

Assuming you mean how are "Lambda Expressions" different from method:
Only syntactically, for all intents and purposes

There's probably more to it if you dig deep into it

[fast relic]

delegates/events are multiple methods that all get called when the delegate/event is invoked

[brazen pagoda]

^ Yeah delegates/events are just "a list of methods", but they are variable in the sense that you can add or remove methods from that list when the code/game/app is running without changing the code itself.

[scarlet aspen]

Why do I see complaints from people taking the course on unity learn about beginner scripting among the comments? Isn't that the right approach to learning coding?

[brazen pagoda]

So for example, you might have a system in your combat code that handles damage and health of a character in the game, but you might want to have your UI and Audio systems do things whenever damage is done to a Unity.

In this case I have simplified the delegate so it has no parameters/arguments because here I'm focusing on showing how a delegate/event changes how code is linked.

Imagine the following code:

public class UnitStats
{
    public int Health;

    public void TakeDamage( int damage )
    {
        Health -= damage; // Simplified code for example only

        UIManager.UpdateHealthbar();
        AudioManager.PlayOuch();
    }
}

This is what's referred to as "Hard coupling" with direct hard-coded links between two systems. There are many reasons why you might not want hard coupling. I'll explain that a bit after completing the example of what events are and how to use them:

Another way to "loose couple" the involved systems is by having the combat system post an event and for other systems subscribe to that even if they are interested in it:

public class UnitStats
{
    public event Action OnDamageTaken;

    public int Health;

    public void TakeDamage( int damage )
    {
        Health -= damage; // Simplified code for example only

        OnDamageTaken?.Invoke();
    }
}

For this to affect other systems they have to first subscribe to the event:

public class UIManager
{
    public void Start()
    {
        PlayerCharacter.UnitStats.OnDamageTaken += UpdateHealthBar;
    }

    public void UpdateHealthBar()
    {
        // Healthbar updating code here
    }
}

This essentially does the same thing - well only for the "PlayerCharacter" in this example. But it's more loosely coupled.

[west sonnet]

So e is like the name of a method that isn't being created in the moment that the defaultInput.Player.Movement.Performed is called?

[brazen pagoda]

e would be the name of the first argument that a method would have.
Lambda expressions don't have "names", those are kinda skipped.

[fast relic]

e is the name of the parameter

[west sonnet]

{
    public event Action OnDamageTaken;

    public int Health;

    public void TakeDamage( int damage )
    {
        Health -= damage; // Simplified code for example only

        OnDamageTaken?.Invoke();
    }
}```

[west sonnet]

What are you invoking here?

In the example above

[brazen pagoda]

Exactly! Great question!!

Events invoke any method that has been subscribed to it earlier

So any method that has been added like so: OnDamageTaken += ....

[fast relic]

-# just don't miss the plus

[brazen pagoda]

In this case that would be the UIManager's UpdateHealthbar since that would have been assigned during Start()

But assume there would also have been an AudioManager with a similar Start() method to the UIManager in which case both the UIManager and the AudioManager would have methods that would be invoked in that case.

[west sonnet]

To subscribe is += and unsubscribe is -= ?

[brazen pagoda]

Correct

[fast relic]

yea

[brazen pagoda]

And it's always a good habit to make sure "if you subscribe once, make sure to also unsubscribe later"

[west sonnet]

So when you invoke OnDamageTaken, it calls the UpdateHealthBar method. Do you have to put a ? when invoking?

[brazen pagoda]

^ So the ? during invoking is just a good habit because it's the same as doing if(OnDamageTaken != null) first. With events this translates to "check if anyone subscribed yet"

If you try invoke an event with no subscribers then you will get an error. The ? avoids that.

[west sonnet]

Lambda expressions only 'exist' when they're being called, right?

It's like a method that doesn't exist until it's called

[brazen pagoda]

^ You can think of it that way. It does exist in memory as long as the app is running I think, but for you, the user, you cannot re-use that expression elsewhere.

And when I mentioned earlier that these expressions are nameless, i.e. why Java calls them "Anonymous functions" is because without a name you cannot call them. So for that intent they do not exist outside of that delegate.

[west sonnet]

So in this example, the 'name' (or really delegate), is 'e'? and that's what's used to call the lambda expression

[brazen pagoda]

^ I'll convert this to a proper method for you so you can do a direct comparison:

defaultInput.Player.Movement.performed += SetInputMovement;

void SetInputMovement(CallbackContext e)
{
    inputMovement = e.ReadValue<Vectro2>();
}

This does the exact same thing as the code you have already

So this should answer what e is I hope

The main thing lambda expression does here is to skip the naming part SetInputMovement that I came up with for this example. Everything else is the same

[west sonnet]

How does inputMovement affect the value of SetInputMovement?

[brazen pagoda]

The above example is still using an event/delegate but is no longer using a LambdaExpression

inputMovement is just some variable in your class somewhere. The code that is executed in both cases is "assign the player's input to the inputMovement variable"

SetInputMovement is just a name I came up with for the method/function that I thought would accurately describe what the code inside attempts to do

[west sonnet]

Okay, I think I'm getting it

So if you did defaultInput.Player.Movement.performed -= SetInputMovement;

It would stop setting the value of inputMovement, because that method is no longer subscribed to that event

[brazen pagoda]

^ correct

[west sonnet]

I'm not sure I understand why you've put CallbackContext e

as an argument

[fast relic]

because that's what the lambda expression has

the e is the parameter, it just isn't typed because the compiler can infer the type for lambdas

[verbal dome]

Probably makes more sense if you take a closer look at performed

[west sonnet]

But that example isn't using a lambda expression

[fast relic]

it's the same as the lambda experssion but without using a lambda expression

[brazen pagoda]

That is the signature that the performed event is defined with and it's the type of the argument that all subscribers to that event must have to be valid subscribers. If you try to subscribe with a method that doesn't have a CallbackContext parameter you will get an error.

[brazen pagoda]

And in my earlier example with healthbars I didn't have to because I defined a simpler event. I used public event Action ... in my definition, but with Unity's performed event the type is public event Action<CallbackContext> ...

[west sonnet]

If you have a method, that you want to be potential subscribers to multiple events, would you have to put multiple signatures?

[brazen pagoda]

^ You would need multiple methods instead, unless all events use the same signature

There has to be a perfect match between the event's definition/signature and all methods that try to subscribe to it.

You can't have any extra parameters in the method, nor can you have fewer. And the type of the parameters has to match exactly.

[limber flower]

i changed my character model from a capsule to a proper model and now it can jump before it reaches the ground, any ideas?

[sour fulcrum]

(unless you compose your own wrapper class)

[west sonnet]

I think your collision mesh is probably misalligned with your new model

Okay, I think I'm getting it. it's super confusing

[limber flower]

i fixed that, the model touches the ground, but after the first jump i can jump again before it reaches the ground

nvm i figured it out

[west sonnet]

what was it?

[limber flower]

the script i use, uses half the playerheight to figure out when its touching the ground, and apparently i needed to keep the original, smaller playerheight, instead of the new taller one

[brazen pagoda]

So a good way to explain how "starting" and "stopping" subscriptions would be useful is by hypothetically extending my HealthBar idea:

Imagine that you only want your UI to show the health of a unit you have selected. If you deselect that unit, or select a different unit, you don't want the healthbar to keep updating when the old unit takes damage.

Example

Here's the old method:

public class UIManager
{
    public void Start()
    {
        PlayerCharacter.UnitStats.OnDamageTaken += UpdateHealthBar;
    }

    public void UpdateHealthBar()
    {
        // Healthbar updating code here
    }
}

Now imagine this instead:

public class UIManager
{
    public void OnUnitSelected( Unit unit )
    {
        unit.UnitStats.OnDamageTaken += UpdateHealthBar;
    }

    public void OnUnitDeSelected( Unit unit )
    {
        unit.UnitStats.OnDamageTaken -= UpdateHealthBar;
    }

    public void UpdateHealthBar()
    {
        // Healthbar updating code here
    }
}

So now instead of subscribing on Start, we subscribe "when the UI is interested in the Unit's damage taken"

This is one of the benefits of Delegates/Events (note that we're not talking about lambdas in this example, just delegates/events).
Delegates are variable - not hardcoded. You can add/remove systems that are "interested" only when that is relevant.

And we could make a hypothetical scenario for the AudioManager too - where the AudioManager is more concerned with whether a Unit is within the camera view or not. Perhaps it is subscribed to multiple units at once since there can be multiple units in the camera view. I won't make example code for this, I think you get the idea.

Another benefit - and this is why Unity makes you have to learn this now - is that a system using events only needs to be concerned with itself, and does not need to know about other systems that are interested in it.

So basically the UnitStats code does not need to be concerned with UI or Audio. And that is good code design. Similarily, Unity's code should not need to be concerned with your code. It's a one-way relationship. It's your code that is interested in what Unity is doing. It's the UI that is interested in the health change, not the other way around. Imagine if you had to dive into Unity's huge code libraries to add calls to your own methods inside there? That would be horrible. Instead you can just add this neat one-line subscription in your code.

Events allows an external system to get notified when an internal system does something. Another perspective is, you can make a system today that has the ability to communicate with a system made in two years without having to go back and update today's system.

[west sonnet]

Okay, I think I'm getting an idea of it

Thank you for all the help!

[limber flower]

im trying to make a script that locks the y rotation of my player model to the y rotation of an object in the scene, but im having trouble figuring out how to write it

this is what i have so far

[west sonnet]

Could do object.transform.rotation.y = player.transform.rotation.y ?

I think

You want to copy another object's y angle to this object?

[limber flower]

yes

[fast relic]

pretty sure you can do transform.eulerAngles.y = object.transform.eulerAngles.y

[brazen pagoda]

This sounds like something that perhaps the Contraint components can do

[verbal dome]

That^, except you need to make a separate variable instead of directly modifying it

[limber flower]

do i do public Transform orientation; at the beginning?

[verbal dome]

Vector3 euler = transform.eulerAngles.y;
euler.y = object.transform.eulerAngles.y;
transform.eulerAngles.y = euler;```

[fast relic]

yea that

[verbal dome]

Euler angles have some issues like gimbal lock but for most situations like this it shouldn't matter

Assuming you have a "traditional" game where world up is always the y axis
