Can you explain how pirates get the benefit. I am providing subscription for ad free experience. in game I am calling the getting products from play store var subscriptionProduct = m_StoreController.products.WithID(subscriptionProductId); it will called on everytime app opens. cant we use that data to validate it?

[languid spire]

because someone pays for it, gets the invoice id, publishes it on social media and then everyone else can mod your game to use the same id

[runic lance]

usually the easiest option is to use Firebase Functions or similar service to provide server-side validation

you don't need user login for that

        }
    }

what im i doing wrong?

[burnt vapor]

Hi, If you want help then please explain the issue you're helping instead of "What is wrong?" because I have no idea what you're referring to

[humble forum]

like the hearts don t display on the screen

when start is called

[burnt vapor]

This code looks wrong. Do you have errors in the console at all?

[humble forum]

noop

[burnt vapor]

Also please screenshot your editor with the code in it if possible

I just want to verify your editor is configured

[sand moss]

ok. I will look into it. thanks @runic lance @languid spire @burnt vapor for your time.

[burnt vapor]

Ah, okay, nevermind. LGTM

What do you want exactly? Do you want the hearts to show up in the game or in the inspector?

Because the former needs actual UI components to appear, or sprites to draw

The latter is because your array is private, and it must be public

[humble forum]

to show the hearts in game and be empty when the player looses a level

[humble forum]

done

[burnt vapor]

This is more a #📲┃ui-ux thing then. Your code already exists, you just have to attach heart prefabs on the gameobjects

[humble forum]

yeah that is why i sent this pic too

fixed it

[burnt finch]

i made a script the deletes an object when it gets touched by the pointerobject. however, if i time it correctly i can stop the objects from falling without deleting it. its like the code didnt reacted to the quick collision. how can i fix that?

void OnCollisionStay2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag("EnemyObj"))
    {
        Destroy(collision.gameObject);
        timeManager.time_left += 5;
        scoreManager.score += 10;
    }
    
}

[burnt vapor]

I believe there's an interval how often collission checks are actually invoked. Maybe you need to reduce that

Can't say where that's done, though

I assume your solution is to reduce it at least

[verbal dome]

How are you moving things?

[burnt vapor]

BTW you could also make this a trigger. Then it does invoke the method but it doesn't stop the object

You'd still have the issue where you could touch it but not trigger the method, though

[burnt finch]

nvm i fixed it by using OnCollisionEnter2D instead

[obsidian plaza]

use on collision enter

oh you got it alredy

[burnt finch]

the red cubes are falling due to gravity and the pointerobj by lerping (idk how its called) the position to the mouse position

[obsidian plaza]

yeah oncollisionstay executes every frame where oncollisionenter actually executes as soon as there is a collision

and physics happens before oncollision stay

[burnt finch]

oh okay

that makes sense

thank you 🙏

[burnt vapor]

Oh, I didn't even realise you used Stay rather than Enter

I assumed it was on a similar cycle

[echo copper]

well, to find this parameter (angle) i use this code:

ANGLE = Vector3.Angle(rotator1.GetComponent<rotator>().collisionpoint - rotator2.GetComponent<rotator>().collisionpoint, Vector3.right);

how to find this parameter?

i tried:

ANGLE = Vector3.Angle(rotator2.GetComponent<rotator>().collisionpoint - rotator1.GetComponent<rotator>().collisionpoint, Vector3.left);

but it returns me the same

rotator1 is this gold point in front of sonic, rotator2 is a white point behind sonic

anyone?

[fickle plume]

Did you check the manual what you should put into a to direction vector? https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Vector3.Angle.html

See example

[echo copper]

do i have mistakes in last code?

[verbal dome]

What does it return, like what is wrong about the output you are getting

[fickle plume]

Resulting angle is the difference, and it seems you are feeding it the same difference just inverted.

resulting in the same difference angle rather

[verbal dome]

Maybe you need Vector2.SignedAngle or Vector3.SignedAngle

[echo copper]

like, he returns me 45 here

and here he returns he 45 too, but he must return me -45

[fickle plume]

Note: The angle returned will always be between 0 and 180 degrees, because the method returns the smallest angle between the vectors. That is, it will never return a reflex angle

Always check manual

[echo copper]

ow... okay... maybe, i should read manual and thinking about the question before asking... my apologies

[verbal dome]

Even if you used Vector2.SignedAngle, both of these images would result in the same angle - see the red arrow. It's the same, just rotated 180 degrees

It's more obvious when you flip the other side

You can use Vector2.SignedAngle and invert the resulting angle when you are facing left

[robust kelp]

guys how can you visualise physics2d.boxcast with physics debugger

[verbal dome]

Or use Vector3.SignedAngle and use a different axis parameter (forward/back) depending on if you face left or right @echo copper

[robust kelp]

should it work fine on default or should i change some settings

[verbal dome]

I think it only supports 3D physics

[robust kelp]

nice

[verbal dome]

You can use Gizmos.DrawWireCube/DrawCube to draw a box anywhere you want

You have to mess with Gizmos.matrix to make it rotated tho

[robust kelp]

chatgpt hallucinated that i had to change 3d to 2d debugger

[robust kelp]

aight thanks

[verbal dome]

It tells you the things you want to hear

Not necessarily things that exist

[robust kelp]

ye i can see it now

[verbal dome]

Lemme know if you have problems rotating the gizmo

Can someone help? Loading files from Application.streamingAssetsPath doesnt work properly on android

[verbal dome]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Application-streamingAssetsPath.html
The doc has some info about android specifically

[fringe plover]

i make call trough WebRequest and it doesnt make the request (download handler is null)
it also uses link that starts with file:///

But when i manualy input "jar:file://" + Application.dataPath + "!/assets" it gives me 404 error

When using Application.streamingAssetsPath

okay...

[snow abyss]

Updated unity and realised that the input manager became a legacy feat
I'm still learning the new input system, just asking how is it compared to the old one?

Does it really provide more flexibility? Since I prefer to implement it through code

[languid spire]

New one allows you to do both, tbh, using it via code is so much easier than the crappy UI-UX unity offers

[swift elbow]

yeah i agree, i never understood why so many people were fond of it

[languid spire]

I don't think anyone is fond of it, they just dont have the skill to do it themselves

[snow abyss]

I just skimmed through some bits of the input system and my head hurts
It looks so convoluted

[languid spire]

it's actually not if you ignore most of it and only look at InputActions

[azure otter]

Hi guys!
Is there any way to have a UI above any GameObject visible in the scene? I want text on a Canvas to always be visible, even if an object is in front of it.

UI Layout:

• Canvas:
• • Panel:
• • • TMP_Text

Thanks!

[snow abyss]

Hmm let me take a look at this, thanks

[astral falcon]

Do not use world canvas but screen space

And not really a coding question

[grand snow]

I think the new input system is good. It lets you configure differnet controls for say gameplay and your UI. How actions work are nice too as you can easily setup say keyboard and controller inputs to go into the action (e.g. WASD or L stick for a Vector2).

[snow abyss]

It looks intimidating at first glance but I'm currently reading lots of good things about it

[grand snow]

You can also get a certain device in code (e.g. get the keyboard and listen for key inputs this way)

[astral falcon]

100% supporting using the "new" input system entirely and do not look back into the old one. The only reason, a lot of people still use it is because of older tutorials.

Its also quite nice to learn about event callbacks and listening for them and so on. Win win 🙂

[snow abyss]

I recently updated my 2021 unity to the latest ver, and there's a lot of things that are already in legacy

I didn't know that TextMeshPro was also gone

[astral falcon]

Its not gone, but its part of unity now

[snow abyss]

oh whoops yep, misremembered

[languid spire]

This is my Gamepad controller set up, used in the editor and at runtime. Code based on new Input system InputActions and ignores the rest of the Unity set up system

[snow abyss]

oo that looks neat, guess there's something new for me to do this week

[final kestrel]

What is the best way to show and hide ui elements? I am using canvas group and just change its visibility via code.

[swift crag]

You can completely disable the graphic components or deactivate the entire game object.

This would be appropriate if you wanted them to stop taking up space in an automatic layout

[final kestrel]

all right. Thanks.

[cosmic dagger]

looks like you already have it working. there are always multiple approaches, so it depends on your needs. as Fen mentioned, you disable the visual component that displays the UI, deactivate the entire GameObject, or change the alpha of the canvas group . . .

[final kestrel]

Ah yeah playing with the canvas group's alpha works fine. I just wanted to know if there are better approaches. I found it myself messing with the UI's so yeah. Thanks.

[tiny wind]

My raycaster wont work properly on my animation object, but it does on my movement object.
The animation when im on the wall wont play when I climb a wall from on its right side

[tiny wind]

 private bool OnWall()
 {
     RaycastHit2D raycastHit = Physics2D.BoxCast(boxCollider.bounds.center, boxCollider.bounds.size, 0, new Vector2(transform.localScale.x, 0), 0.1f, wallLayer);
     return raycastHit.collider != null;
 }

this is the code I used, I have tried to fix it by changing the size of it to be the same size as the object or larger than it, but it didnt work

[wintry quarry]

Are you not using the same BoxCast for both?

I would think this is a problem with whatever code is supposed to set that "CLIMB" parameter, not the boxcast itself (which theoretically is the same for both)

[tiny wind]

im using the same

[tiny wind]

that is the code that sets the CLIMB parameter

        anim.SetBool("CLIMB", OnWall());

[wintry quarry]

You need to show it in context lol

can't do anything with this

show the full script ideally

where's the wall climbing logic

thats just for the animation,

wait, I think i see the problem? idk how to describe it

[cosmic dagger]

check here for how to post code properly . . .

[verbal dome]

FYI, Rigidbody2D.linearVelocityY/X exists now if you want to just change one axis of your velocity

[burnt vapor]

Seems like an honest mistake if you read up

[north scroll]

where is the freezing xyz positions? Im pretty sure ive used this option before but I cant find it in the rigidbody or box collider, and online sources have it through code instead of inspector

[verbal dome]

Your inspector is in debug mode

[north scroll]

my hero

no clue how I got that going though lol, whats the difference

[rich adder]

Debug mode will show all the private fields among other things

[obsidian plaza]

its helpful for certain things like in a scrollbar when choosing how many steps you want

its capped at 11 outside debug mode

thats what i use it for mainly off my head

[swift crag]

the debug mode skips all of the normal editor and property drawer code

it just kinda...shows every serialized field, in order

They're completely transparent

The scene view is drawing an outline around the particles

what does it look like if you turn off outlines?

They won't run outside of Play Mode when not selected

hm, so they appear in the game view, but not in the scene view?

[fervent abyss]

yeah ive been told just now and its real

i can see in main camera

awesome unity features

[swift crag]

I haven't observed that before. I wonder if it's a rendering-order problem

[twin bolt]

Yesterday, i was getting help from some people here, and i was told to change my method of closing the doors in my game. So far, there is no more "Shaking", BUT now the door is rotating like this, and i stopped getting help. Here is the code: https://hastebin.com/share/rigapegomi.csharp

[languid spire]

As far as I can remember that code is nothing like that which you were advised to use

[twin bolt]

Praetorblue helped me alot with the code: Most of the code is for my scene, but the stuff i was told to change is here: ``` CurrentRotation = Mathf.MoveTowardsAngle(CurrentRotation, newYRotation, 1 * Time.deltaTime);

        Door.transform.rotation = StartRotation * Quaternion.Euler(0, CurrentRotation, 0);```

This is the code after i fixed it how praetor told me.

[verbal dome]

I think StartRotation should be cached in awake/start instead of ontriggerenter

[languid spire]

I'm pretty sure there was a lot more to it than that, I suggest you revist the conversation

[twin bolt]

The reason it isn't is because the player is meant to hit a trigger, so it would be stored then.

[swift crag]

I don't like how you're trying to remember a starting rotation at all, really

[wintry quarry]

1. The object you have selected doesn't seem to be the one rotating
2. Your inspector is in debug mode which makes it hard to understand the data

[swift crag]

Just operate in local space. The door should only care about changing its local rotation.

That makes it trivial.

[verbal dome]

I had the same thoughts

[swift crag]

You're piling on a bunch of complexity by trying to use a world-space rotation

Dead-simple.

https://paste.myst.rs/2s0aiy8m

Set up the door so that it is closed when its local rotation is [0,0,0]

(or, heck, any other y-axis rotation -- just plug that value into closedAngle)

and then put angle = closedAngle into the Start method in that case

[twin bolt]

I'm not sure whats happening for me:

[wintry quarry]

How are you doing the "open door" part

you never showed that

and that's working fine

[swift crag]

It does seem odd that the door's opening has nothing to do with the door's closing, yes

That implies you have multiple components all trying to spin the door in various ways

which sounds nightmarish

[wintry quarry]

indeeed

[swift crag]

the door should have one component whose sole job is to rotate the door based on its current state.

Other components can tell the door to change it state.

But they shouldn't be trying to fuss with its rotation

[languid spire]

pretty sure you pointed him in the right direction for doing this

[verbal dome]

Why does it have a hinge joint

You can't mix both physics and transform

[swift crag]

Uh Oh

💥

[twin bolt]

I have a door dragging mechanic in my game, that does that, but I'm trying to create a mechanic that closes the door back.

[twin bolt]

Oh well that explains it.

[swift crag]

You can ask the hinge joint to move to a certain angle using its Motor setting

[verbal dome]

If you need it to be physical then yeah that^

[swift crag]

er

[verbal dome]

Or limits
Nvm yeah just use the motor

[swift crag]

its spring position property

Joints are a whole bundle of joy

[twin bolt]

Could i add force to the door?

[swift crag]

Fun fact: if you have Scene Reload disabled, then joints will remember things from prior play sessions

You'd want to add a torque!

But yes, you can do that

In that case, you'd write a function whose job is to apply torque until the door is in the right orientation

[twin bolt]

OKay, well that explains why i have this issue. That makes sense.

[swift crag]

(it should also give up after a period of time)

[swift crag]

eh, your problem is that you're rotating a thing that is also being controlled by a Rigidbody

[twin bolt]

Yeah, i completely forgot about that, that would have saved alot of time yesterday.

[verbal dome]

Always good to show the components when debugging

I just happened to see it flash in the beginning of the video

[twin bolt]

Thank you.

[feral moon]

How can I prevent the player from getting stuck in the air while jumping and activating a dialogue?

[cosmic quail]

dont turn off gravity for the player when dialogue gets activated

[verbal dome]

Are you setting timescale to 0?

[feral moon]

I'm just freezing the character...

[cosmic quail]

you can just disable input instead

then gravity will still work

[feral moon]

😉

[verbal dome]

You need to set your movement input to zero obviously

[gloomy cosmos]

Hello, are there any cool tips on how to make functions with loads of parameters more readable? (this is me with having definined a bunch of stuff in vars before hand to shorten it)

I wish I could make radius and center have default values, but since Vector2.zero is not compile time constant you can't

[cosmic dagger]

the parameters should describe what it's used for in the method . . .

[slender nymph]

you can easily do this with an overload that doesn't have those parameters but just calls the overload that does and passes your preferred defaults

[gloomy cosmos]

oh parameters is a dictionary, its used to pass extra data to the bullet scripts (dw about it)

[gloomy cosmos]

wait thats such genius, although kind of annoying to make a bunch of variations

but I'll do it, thanks

[cosmic quail]

cant you do this? public void SpawnCircle(Vector3 radius = default(Vector3))

[cosmic dagger]

yeah, overloads with default (optional) values are pretty common . . .

[gloomy cosmos]

oh apparently I can, had no idea that was a thing

[gloomy cosmos]

yay thanks, its a bit more readable now

[cosmic dagger]

just remember that optional parameters must be at the end . . .

[gloomy cosmos]

Doesn't localization package handle that automatically? Anyway if you're going custom I think there's a setting for that on TMP Text (I could be wrong)

(btw localization package is the best thing ever, like the only thing I import everytime)

[cosmic dagger]

if you're passing in this many arguments, it's best to use a struct or a class . . .

[languid spire]

do you not have a programmer on your team, this is pretty trivial

[gloomy cosmos]

would it really be better though? Just more overhead, and you'd be creating the wall of parameters in a struct and then immediately passing it anyway. It'd be more code overall to do the same thing

[languid spire]

if this is modding or decompiling you are in the wrong server

[gloomy cosmos]

ok buddy use pastebin atleast, i cant even look at all that in discord (without downloading file)

also what is Token? I've legit never seen it

anyway you should probably learn unity or get a friend to help, its kind of hard for anyone here to help with such a specific issue if you dont know what you're doing

[cosmic dagger]

it's just an idea. definitely more readable and you can set default values as needed. that was your original question, no? you can also re-use the data, if needed . . .

[feral moon]

It's working! Thank you for your helping!

[crimson pike]

any concerns about using UnityEvents from a singleton?

[cosmic dagger]

unity events are only used if you need to hook up events from the inspector. if not, use a regular event (action) instead . . .

[crimson pike]

Action<object[]> but yeah ok

ah wait, actually i kinda might want that too

this one is programmatic but you're saying i can configure them in the editor this way? like if i made a public or serialized field list for them on my GameData?

mainly want a way to allow entities to call out to other entities. in this case it's setting the background terrain scroll speed (nested in a TerrainManager) from an actor in a cinematic sequence

[cosmic dagger]

the UnityEvent will appear in the inspector, then you would drag a GameObject with a MonoBehaviour script attached to it that has the method you want to invoke. using the drop-down, you select the method from the script

if you're not going to do that then there isn't a reason to have/use a UnityEvent instead of an Action . . .

[crimson pike]

Yeah that sounds perfect actually. Thanks

[lapis veldt]

Hello. This is my first time when I want to put some scripts to an downloaded asset (character, animal etc.). I have a small problem. I made an HP script where the character will take damage when hit (in this case, the tiger is hit by a projectile), but it's HP isn't dropping or dissappearing. Where should I put the HP script?

[glossy turtle]

What is the git URL for socket.io package do you know any.

[cosmic dagger]

how do you determine if the tiger is hit by the projectile?

[lapis veldt]

using a collider (I had a capsule with it and it does work)

[cosmic dagger]

make sure the collider is setup correctly to collide with the projectile. besides that, we don't know what method you use to damage the tiger or how the collision interactions works. you have to provide that information to us . . .

[lapis veldt]

yeah, it was because of the collider

idk why, but I though when I download a character asset, it would come with a collider in it

[glossy turtle]

Anyone know git URL for socket.io package?..

[slender nymph]

have you bothered googling it?

[glossy turtle]

I tried but not finding.

I installed one but it has errors.

Rochet

[obsidian plaza]

the script could go anywhere, it depends on what the script is doing and how you want to organize it. Maybe its a bug in your code instead of where the script is placed, in that case do some debugging

or did u figure it out

[gleaming turtle]

i've got a question i know for a fact has been asked a million times & i bet is simple but i can't find anything simple online to fix

i am trying to throw projectiles in my game, specifically spears & i need the flight path of the spear to follow the head, image in case i'm not explaining myself very well. it's all physics based & there is no script on each object that gets launched

[lapis veldt]

I did figure it out

[glossy turtle]

There are only two persons who are offering socket.io package on GitHub but they are full of errors. The other one is nan but i didn't tried it.

[obsidian plaza]

a lot of the times, the best way to do something is by doing it how it works in real life

and in this case that means making the spearhead the heaviest part

which would make it do this naturally

[glossy turtle]

Few sites are showing to install it through git URL so are there any git urls for socket.io or socket.io client package.

[slender nymph]

seems like you've already found the available ones. i don't know what else you are expecting to hear

[woeful bridge]

I'm really confused

    private void DefaultListener(String string)
    {
        Debug.Log("Default listener triggered!");
    }

    // Update is called once per frame
    void Update()
    {
        onCustomEvent?.Invoke("Rats");
    }```
How can I do something like this

[slender nymph]

what about that is not doing what you want?

[woeful bridge]

I can't pass parameters to my listener

how do I do that

[slender nymph]

use a delegate that has parameters

[cosmic dagger]

does your listener have parameters?

you do that part yourself . . .

[woeful bridge]

I gotta type the fucking listener??

oh brother

[obsidian plaza]

what

[slender nymph]

how about you show where you've declared the onCustomEvent so someone can point out what you've done wrong since you clearly don't understand the information that was provided to you

[woeful bridge]

public UnityEvent onCustomEvent;

onCustomEvent.AddListener(DefaultListener);

[obsidian plaza]

lol

[languid spire]

this 'String string' wont work either

[cosmic dagger]

how does it know you have a parameter if you don't tell it, it has a parameter. it's the same way you create a list. you tell it what type of list it is . . .

[glossy turtle]

They are full of errors box. I am not finding without errors. Did you worked on socket.io.

[woeful bridge]

I miss non typed languages

ok I'll type it

[obsidian plaza]

lol i think ur missing something

[slender nymph]

okay so now look at the documentation and you'll see that there are generic versions of UnityEvent that look like UnityEvent<T>, use that but use string for the generic type parameter

[slender nymph]

how about instead of bitching that c# isn't a shitty dynamic language, you maybe try and bother learning how it actually works?

[woeful bridge]

Do be what I'm doing

[slender nymph]

no i haven't. but you've found the available resources. if they do not work then either fix them yourself or do everything manually

[woeful bridge]

Using C# is learning it lol

[cosmic dagger]

i think if they did, they would've mentioned it by now (at the very beginning) . . .

[languid spire]

it's exactly because of lazy programmers who wrote shitty code that type safe languages were invented

[slender nymph]

seems more like you're skipping the "learning how c# works" and going straight for "brute forcing your way through c# and expecting everything to work like lua"

[woeful bridge]

Wtf more am I suppose to do? Learn C?

Like I learned C#

[slender nymph]

did you though

[woeful bridge]

I can take a college class I guess

[naive pawn]

or like, free online guides

[woeful bridge]

I did

[cosmic dagger]

that'll enable god mode, if you can beat it . . .

[glossy turtle]

Learn c first.

[slender nymph]

copy/pasting what you see in tutorials is not the same as actually learning and understanding

[gleaming turtle]

i tried this & it didn't work but let me try again a little bit harder

[woeful bridge]

I'm looking at docs not tutorials

[cosmic dagger]

sure, YouTube University . . .

[woeful bridge]

True!!

[slender nymph]

great! so instead of reading documentation you clearly don't understand, start by learning how the language works

[untold shore]

Okay, having some difficulty just…thinking through a plan. I want to remove all children of an object in one frame, then in the next, have two objects added as children to that original object. This would be in a method whenever a button is pressed. What would y’all’s process be? Don’t want yall to code for me (I need to learn), but would you start with a method? Coroutine? How would yall think through it?

[naive pawn]

if you don't have enough background knowledge/experience to understand them, they're not gonna be as useful as they could be

[naive pawn]

why the 1-frame difference?

[slender nymph]

so you remember that information about coroutines i provided to you yesterday? read through it

[obsidian plaza]

yeah i would do the 1st thing then yield return null in a coroutine then do the next

[untold shore]

So the Destroy() can fully work, as there would be an issue as all the objects have a max amount

[cosmic dagger]

does it have to be the next frame? why not remove all children, then add the two children afterwards?

[languid spire]

Coroutine is the obvious choice if you want a frame pause

[cosmic dagger]

if so, use a coroutine . . .

ahh, too slow . . .

[untold shore]

I do, so would I just do a coroutine?

[obsidian plaza]

be careful with unity’s destroy command, the objects destroy on the next frame, not the current btw

[slender nymph]

yes, a coroutine would be the easiest option here. or you can always go and refactor your code so that it isn't relying on the number of children an object has and instead is using some collection to track the number of objects

[languid spire]

they destroy at the end of the current frame

[cosmic dagger]

its at the end of the frame . . .

[mighty compass]

Just go to W3 schools and study its lessons on any language, pretty much explains the concepts in itself.

[swift crag]

yes

[obsidian plaza]

or nvm lol its probably end of frame as they said

[untold shore]

Alright, thank yall. Going to look at the docs boxfriend sent me yesterday on coroutines, still getting used to them. Thank yall!

[swift crag]

it would be complete insanity for C# to grab random methods by name and subscribe them to the event

[obsidian plaza]

i just know it was annoying to check if something existed when it wasnt actually destroyed yet

[mighty compass]

I was pretty lost in Unity until til I started college tbh lol

[slender nymph]

yeah that was their issue two days ago

[untold shore]

It DEFINITELY is 😭

[swift crag]

oh, you mean "give it the correct type", not "type it with your keyboard"

[obsidian plaza]

lol

[rich ice]

transform.forwards = rb.velocity.normalized

[untold shore]

Surprised yall remember this. It’s very sweet tbh

[swift crag]

my response remains roughly the same. static typing keeps me sane.

[woeful bridge]

LMAO

[mighty compass]

No way to really know shit about what’s going on unless you do some learning about the language and concepts of programming

[swift crag]

I've worked on game written in javascript before, and it's hideous

It's so nebulous and ill-defined

[woeful bridge]

I got the brain chip to type my listeners

[swift crag]

Does it work? I don't know!

Runtime error!

💥

Being able to do static analysis beyond "I think this variable probably exists" is so, so helpful

[slender nymph]

i'm going through information about js now for some web dev stuff and this language is horrifying

[swift crag]

Typescript is a huge improvement

[mighty compass]

Yeah I made a simple rogue like in html,css,JavaScript, it’s unnecessarily unorganized

[swift crag]

The TS type system is really cool

[woeful bridge]

I'm so sorry for you js was rough for me lol

typescript was nice tho

[mighty compass]

I think js can be nice if you include a database

[glossy turtle]

I liked js.

[slender nymph]

one thing about js that is absolutely baffling, is that when calling a function with a string literal you apparently can just leave out the parentheses

[naive pawn]

you can't

[mighty compass]

Yeah i dont know about that lol

[naive pawn]

do you mean a tagged template? that's a bit more involved than "pass a string without parens"

[mighty compass]

Js doesn’t specify type so technically you can pass any type to a function, doesn’t mean it will work though lol

[glossy turtle]

There is one bit annoying about js is you have figure out runtime time errors.

[slender nymph]

i mean, this is valid: console.log`hello world`

[naive pawn]

yeah that's this
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#tagged_templates

[mighty compass]

Oh I see

[naive pawn]

but it's specfically for template literals, not string literals

and it does more work when you actually use templates

console.log isn't written to use them, it's just allowed and happens to work

split and join also work like this, handy tips for golfing

[mighty compass]

One thing I always wondered is what is the point of arrow functions in js

[swift crag]

i remember using this in a CTF

[swift crag]

you mean anonymous functions?

they're wildly useful

[mighty compass]

Yeah

[swift crag]

just as they are in C#

() => Debug.Log("Hiiiii");

[naive pawn]

@slender nymph

[mighty compass]

Can’t u just do the same thing by leaving the function parameters empty

[swift crag]

are you comparing it to a named function?

[naive pawn]

it's syntactic sugar

[swift crag]

the point of an anonymous function is that it has no name -- it's just an object

[mighty compass]

But what’s the point of it lol

You can just write its contents on its own to execute

[naive pawn]

a => b is syntactic sugar for function(a) { return b; } in js

[swift crag]

you often want to run something later

[naive pawn]

technically no, non-arrow anonymous functions also exist in js

[mighty compass]

I fail to see its benefits

[naive pawn]

not when you need a callback

[swift crag]

oh, by writing it like this? #💻┃code-beginner message

been a hot minute

[mighty compass]

What does it look like in c#?

I’m a Java/python andy atm

[verbal dome]

void a() => b();

[naive pawn]

if you want to add 1 to each element of an array, you can't just map(+1), you have to do write a function for it, like one of these

function increment(x) {
  return x + 1;
}
map(increment)
// or write a function directly
map(function(x) { return x + 1; })
map((x) => { return x + 1; })
map((x) => x + 1)

[swift crag]

ah, i see

[slender nymph]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/lambda-expressions

[swift crag]

interesting

[naive pawn]

yes, but with arrow functions it's not very common anymore, unless you need a new this for some reason

[mighty compass]

That looks wild

[slender nymph]

this isn't even an anonymous method, this is just expression body syntax for a regular method

[swift crag]

yes

[naive pawn]

they're all basically the same
c#, java use syntax (arrow) while python uses a keyword (lambda)
while js has both

[gleaming turtle]

how would you suggest to do this? i've tried adding in a secondary, heavier, rigidbody but this doesn't affect it. I've seen that you can edit the rigidbody centre of mass in code but i don't have scripts on these objects

[mighty compass]

I haven’t used the arrow in Java

[naive pawn]

have you done streams in java

[mighty compass]

I’ve done things like generic, making interfaces, abstract classes

I never learned about the arrow

Streams???

[naive pawn]

streams are where you utilize lambdas the most so if you never touched on streams then you probably wouldnt have had to use them

https://dev.java/learn/api/streams/

[mighty compass]

By streams are you talking about cryptography? Lol

[naive pawn]

no

[slender nymph]

bascially java's equivalent of linq

[naive pawn]

yeah, fp-style manipulation of collections

(in comparison, js has this built into Array, python has map/filter, and also comprehension)

[mighty compass]

I dont know what linq or fp is

[naive pawn]

have you ever used Array.map in js or comprehension in python

[mighty compass]

No

[obsidian plaza]

i dont do a lot of physics stuff like this honestly so i would have figured that a second rigidbody would work. Have you confirmed that separately, the 2nd rigidbody falls faster?

[mighty compass]

Does that have to do with dictionaries?

[naive pawn]

😭 bro i can't even give you equivalents in those languages

[naive pawn]

not really, more about data structures in general

[slender nymph]

linq: https://learn.microsoft.com/en-us/dotnet/csharp/linq/
and fp is just functional programming

[gleaming turtle]

i've found that you can manually edit the centre of mass so i'm playing with this now, i haven't confirmed that first though

[mighty compass]

Ohhhh

Just queries

[naive pawn]

map/Select, filter/Where/select, reduce/fold, flat, etc are operations on collections

[mighty compass]

That’s basically what the arrow is?

[slender nymph]

well no, but it's used frequently with those

[naive pawn]

no, that's just where arrows are utilized a lot

lambdas are functions as objects

[mighty compass]

What is the arrow doing syntactically

[naive pawn]

it creates a function

[mighty compass]

Like if you could write it in code

[obsidian plaza]

think its just { }

[mighty compass]

What would the arrow look like

[slender nymph]

#💻┃code-beginner message

[mighty compass]

Thx I’ll check that out haha

[naive pawn]

params -> body or params -> value

[obsidian plaza]

i use it a lot in something like a list of a script where i need to find the first thing in a list where x is true, i can do it in one line

[mighty compass]

I kinda get it

What is with the <> in

Func<int, int> square = x => x * x;

[slender nymph]

generic type parameters

[mighty compass]

In Java that specifies generic

But this is specifying such a primitive data type for a generic

[naive pawn]

fyi: these are broadly called anonymous functions or lambdas/lambda functions/lambda expressions, for example python has the keyword lambda which does the same thing but it doesn't use an arrow

[naive pawn]

it's also a generic

[mighty compass]

It’s just weird haven’t seen that much lol

[naive pawn]

c# just doesn't restrict generics to reference types

[swift crag]

You want weird?

[mighty compass]

I would always see a generic with a class name not a primitive

[swift crag]

C++ templates let you do crazy stuff like Foo<3>

[swift crag]

They're both types.

[mighty compass]

That is true

[swift crag]

Nothing weird about a List<int>

[naive pawn]

java has a different generic system to c# but they're still generics, the core logic holds

[mighty compass]

Man there’s a lot more to c# than I thought, I thought it was basically the same as Java lol

But there’s namespaces that apparently act a lot different than packages

And some other stuff

[naive pawn]

java doesn't let you use primitives with generics and instead provides wrapper reference types
c# doesn't separate primitives in this way, users can define value types themselves (struct) so it wouldn't make sense to restrict value types, so c# doesn't have wrapper types

[swift crag]

Ah, that is an important thing

Java doesn't let you do that, yeah

[mighty compass]

Right, that’s where I was confused

[naive pawn]

java doesn't have structs or this concept of value types

[slender nymph]

they are both syntactically similar, but there are some surprising differences, like in java you can't define your own value types. everything you create is a reference, the only value types in java are the primitives

[swift crag]

I believe that's because each instasntiation of a generic type with value-type parameters winds up affecting how much memory the type requires

public class Holder<T> {
  T item;
}

[naive pawn]

not to be confused with value-based types

[swift crag]

The size of a Holder<MassiveStruct> is larger than a Holder<int>

Bit of a headache.

[naive pawn]

java's type erasure kinda breaks that i guess

[swift crag]

it's different in a way that's entirely unlike Holder<Foo> vs Holder<Bar>, where both of those are reference types

[naive pawn]

templates feel so cursed to compare with generics lmao

[swift crag]

The C++ template section opens up with talking about how you can't use floats

[naive pawn]

array<int, 5> moment

[swift crag]

like, it's the first thing it talks about

as if this were normal

and that we all wanted to do that

[naive pawn]

and anything else is fair game? 😰

[swift crag]

That was the only section of the C++ standard that I could not understand by reading it

[mighty compass]

How do you define your own type in c#??

[naive pawn]

struct/class/interface/enum

[mighty compass]

Java just has references to objects yeah

[slender nymph]

every class, struct, enum, interface, etc is a type definition

damn too slow again lol

[mighty compass]

Lol

[naive pawn]

same as you would in java/js/python

[mighty compass]

Wait so it’s basically the same in Java

[naive pawn]

you define a class, or similar constructs

yeah

[mighty compass]

You have to make a class and reference it

Or any of those other obects

[naive pawn]

you, or someone else, has to make everything you want to reference

no language will automatically know what you mean by some given name unless it's defined

[mighty compass]

Is Unitys source code in c++ or c#?

[slender nymph]

yes

and by that i mean, it's both

[mighty compass]

Hahaha

Howcome they chose to abstract to c#

[naive pawn]

why did you choose unity?

[mighty compass]

Someone told me it’s better for solo devs lol

[naive pawn]

damn, wasn't what i was expecting

[mighty compass]

And apparently offers more freedom

[naive pawn]

ok that's more like it

[mighty compass]

You can do more custom things with it

Which doesn’t make sense

[naive pawn]

so a variety of reasons, yeah?

[mighty compass]

Because it’s abstracted to a higher level language

[naive pawn]

same thing for any other decision

[mighty compass]

Unity seems somewhat user friendly though

[naive pawn]

i mean, so are all the other engines, they gotta be to be usable

[mighty compass]

And I was told that Unreal offers a ton of prewritten templates which I didn’t like

I like doing everything from the lowest level, and from scratch

Because I’m still learning programming, and I need to learn that way

[cosmic dagger]

you can write your own stuff in Unreal if you want . . .

[mighty compass]

Probably lol

[slender nymph]

and you can use templated stuff in unity too (hence the entire asset store)

[mighty compass]

I opened unreal and had no idea how to access anything, like scripts or anything

[burnt vapor]

Isn't an Engine by itself technically a prewritten thing?

[mighty compass]

When I opened Unity I saw the scripts at the bottom of the screen

Yeah, I’ll probably attempt making my own engine at some point 😂

[burnt vapor]

Like, if you truly want to do things yourself use a C# base and write an engine yourself

[naive pawn]

doesn't unreal have the same basic interface as unity

[mighty compass]

I know in one of my classes they make you write a basic 2d engine in c++

[burnt vapor]

Assuming you have the time and patience, it's a hell of a thing to do and a great learning opportunity

[mighty compass]

I dont know I spent 30 minutes on it, and figured I should go back to Unity because I didn’t know how to do anything

[naive pawn]

project - content browser
inspector - details
hierarchy - outliner

[mighty compass]

I just want to make a working 3d multiplayer fps in unity before I do anything else

[naive pawn]

that's why guides exist lol, noone's expecting you to spontaneously understand it

[gloomy cosmos]

Hello, I'm currently baffled at C#, and would very much appreciate help.

This is the print:

Processing task at index 0```

Error cause by RemoveAT:
```ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index```

How? The list is private, nothing outside can access it, I do reverse indexing to ensure no problems when removing elements while iterating, yet it breaks. How is this possible?

This is the code:

[mighty compass]

I know haha, I just looked at it and figured I barely know Unity, and this looks more complicated so I went back to learning Unity

[gloomy cosmos]

also before anyone mentions using fixedTime in Update, this is not a monobehaviour, be sure that this function gets called externally in FixedUpdate

[burnt vapor]

What type is your collection? List?

[gloomy cosmos]

Yes

[burnt vapor]

Can't you just reverse the list, do a normal foreach, then remove all?

[naive pawn]

or use a queue to let the removal of items be managed

[gloomy cosmos]

I mean yes, but thats technically slower and I can't think of any actual reason for this to not work

[burnt vapor]

A queue is even better here, yes

Removes basically any trivial operations apart from just iterating

[untold shore]

Hey, quick question. Currently attempting to call a coroutine in another script, but it won't "call" it. Still new to all this, so if this is idiotic I understand, but when you call a coroutine, does it have to be inside another coroutine? Here's the code calling the coroutine:

public void ResetCurrentHand()
    {
        PlayerDeckManager.GetComponent<DeckManager>().ResetPlayerHand();
        DealerDeckManager.GetComponent<DealerDeckManager>().ResetDealerHand();
    }
``` and the coroutine itself:
```cs
  public IEnumerable ResetPlayerHand()
    {
      Debug.Log("Reseting Player Hand");
      foreach (Transform child in transform)
      {
        Destroy(child.gameObject);
        Debug.Log("Destroyed an object");
      }
      yield return null;
      Debug.Log("Coroutine ended");
      handManager.cardsInHand.Clear();
      Debug.Log("Cleared cardsInHandPlayer");
      StartCoroutine("DestroyPlayerHandObjects()");
      hand.GetComponent<CardValuesScript>().handValue = 0;
      Debug.Log("Number of children in handtransform before waiting: " + hand.transform.childCount);
      DrawCard(handManager);
      DrawCard(handManager);
    }
``` Thanks

[gloomy cosmos]

Sure I can make a queue instead, but like why does this cause an error? I can't think of any reasons

[burnt vapor]

Alternatively if you need a LIFO collection, use Stack

[gloomy cosmos]

you have to use StartCoroutine

[naive pawn]

try debugging the count and index right before you remove

[slender nymph]

https://unity.huh.how/coroutines/startcoroutine

[gloomy cosmos]

but I do, look in the code

[naive pawn]

right before you remove

[gloomy cosmos]

alr

[untold shore]

That's the thing, whenever I try to, it won't call it. I've done StartCoroutine(ResetPlayerHand()), in which it will say it is not a string or inside the script currently opened, and when I do the string (StartCoroutine("ResetPlayerHand") or ("ResetPlayerHand()"), neither will work

[gloomy cosmos]

I just realized what's going on, when my object is destroyed it clears the list (to ensure no schedules run after), but it happens before the update... Fixed and very stupid of me

[obsidian plaza]

you are changing the count of the list while it needs that information inside the for loop? not entirely sure but i dont think u should be removing in here

[naive pawn]

you still need to reference the function correctly, StartCoroutine(PlayerDeckManager.GetComponent<DeckManager>().ResetPlayerHand());

[gloomy cosmos]

it normally wont matter due to the reverse indexing

[slender nymph]

don't use strings. and you call StartCoroutine and pass in DealerDeckManager.GetComponent<DealerDeckManager>().ResetDealerHand() or give the deck manager components a method that starts the coroutines internally

[rich adder]

public void ResetPlayerHand() {
  StartCoroutine(ResetPlayerHandRoutine());
}
private IEnumerator ResetPlayerHandRoutine(){ 
  ..etc
}```

[obsidian plaza]

ah i getchu

[burnt vapor]

Doesn't matter considering this is in reversed order and the total length isn't used

[untold shore]

That makes... a lot more sense. Thank you.

Real quick though, it still says I need a string when using StartCoroutine?

[naive pawn]

it needs to be IEnumerator, not IEnumerable

[burnt vapor]

Your Coroutine needs to be an IEnumerator

IEnumerable is for collections

[untold shore]

Yeah, that checks. 😅

[burnt vapor]

It's just that a Coroutine using a string is probably the first signature defined to it errors mentioning that one

[woeful bridge]

I did research on get and setters since I made it to the part I needed them and there kinda awesome so thanks theres way different than I thought so very cool

[verbal dome]

Oh I know, I thought we were talking about this #💻┃code-beginner message

[slender nymph]

yeah but that was javascript syntax which are anonymous methods

[slender nymph]

yeah properties are super nice

[verbal dome]

Ah okay, got it

Haven't really touched JS and from everything i've seen/hear I hope I never will

[slender nymph]

it's a crazy language that i wish i didn't need to know about

[burnt vapor]

I feel like you guys have had a bad experience with an actually interesting language

[gloomy cosmos]

Hello, apparently my problem was not fixed. I removed the clear code, it was not the issue. The only thing which affects the problem is whether I call Invoke or not. I commented out ALL the code in the function getting invoked, it still causes the error only if invoke is called. Even if it's called AFTER I call RemoveAt

[burnt vapor]

It's just that everything around the language is trying to be the best

[gloomy cosmos]

Take a look at this:
it prints "a 1", then immediately throws error at RemoveAt. If I comment out the task.Task(), then no error occurs. The task getting called is literally empty.

[naive pawn]

"interesting"

[burnt vapor]

Things you will never experience if you just use the language like a normal person

C# also has these

[naive pawn]

(yes, but it's funny)

[burnt vapor]

Yes, it's very weird

[naive pawn]

i do use quite a few languages and passively hate all of them 🙂

[gloomy cosmos]

This is so bizarre, I can confirm that in this code the Task never gets called. However if I comment out the third line, it works perfectly fine with no errors at RemoveAt. Like what the actual hell??

[naive pawn]

this feels like a race condition

i had that vibe from the original code but i can't pinpoint it

[gloomy cosmos]

but the task does NOTHING but Debug.Log

i have no idea what kind of c# illuminati bs is going on, Im gonna make it store things to remove in a list each frame and remove that stuff at the end of the frame

[naive pawn]

wait what's task there

[cosmic dagger]

don't use Task, use coroutines instead . . .

[gloomy cosmos]

Task is just a name, its a System.Action<float>

[cosmic dagger]

wha? confusing AF . . .

[gloomy cosmos]

yeah sorry, not the best naming scheme

Hope this clears it up

[naive pawn]

so how's task defined here?

[gloomy cosmos]

this

literally thats all it is

[cosmic dagger]

wait, are these anonymous delegates?

[naive pawn]

how is task, the variable, defined

[slender nymph]

that's object initializer syntax for some ScheduledTask object they've created

[gloomy cosmos]

Bullet.Schedule is the schedule function from above, RunSpawner is task, 1f is delay

[gloomy cosmos]

im not 100% sure what this means, but you can see in the ss how I use .Schedule()

[cosmic dagger]

i was referring to task, like Chris was asking since we had no idea how the Action was defined . . .

[naive pawn]

[gloomy cosmos]

sure, Ill put on pastebin in a sec

https://pastebin.com/xwvKdwfQ

[slender nymph]

and just to confirm, the exception is being thrown on line 40 and not line 41 now?

[gloomy cosmos]

Yes

the print in the task never runs at all

[naive pawn]

yeah that seems like it'd break on line 41

have you tried adding a Debug.Log between the remove and the call

[gloomy cosmos]

as I said, I'm baffled. SOmehow commenting out code that hasn't yet ran fixes it

[naive pawn]

you're referencing tasks[i] there

after it's removed

[slender nymph]

this really points to the exception being thrown on line 41 then

[gloomy cosmos]

Ill add

[gloomy cosmos]

I double checked, its not

[slender nymph]

make sure you've saved

[gloomy cosmos]

I will run with print in between

[rich ice]

i haven't chat. so, im not sure if this is what you guys are currently talking about. but, does anyone know of a shorter way of doing this?

    public float time;
    
    float t;

    private void Update()
    {
        t += Time.deltaTime;
        if(t >= time)
        {
            //code here
        }
    }

[swift crag]

note that this this script doesn't include the using directives, so the line numbers will not match

[gloomy cosmos]

Very strange, I added the inbetween print now unity repots the print line causes the error. I guess you guys were right, no clue why its showing wrong line

[naive pawn]

shorter way of.. doing what exactly?
if the goal is just to compare 2 numbers you can't get much shorter than that

[slender nymph]

again, make sure you've actually saved and recompiled. and if you have any assets that fuck with compilation like hot reload, then disable them or restart the editor

[gloomy cosmos]

yes I know, the file contains several classes so it was mismatched anyway

[rich ice]

my bad, just fixed it

a timer

[naive pawn]

generally "shorter" is not the right direction to go it

[gloomy cosmos]

I thought that using var element = List[i]; would cache it, but I guess not. Thanks for the help, I think it's fixed now

[naive pawn]

you should go for stuff like more readable, more generalizable, more elegant, more flexible, etc
you could use coroutines for example

[swift crag]

well, hang on a minute

[naive pawn]

with this approach, you could set t as some time in the future and check that against deltaTime instead of adding to it, for example

[slender nymph]

that would, but on line 41 of what you showed you were still accessing by index. what did you actually change to fix it?

[gloomy cosmos]

I guess technically if you wanted to you can steal the schedule code that I posted, it does pretty much that

[cosmic dagger]

not really a shorter way but using a coroutine or a Timer class is more readable and reuseable . . .

[verbal dome]

{
        if((t += Time.deltaTime) >= time)
        {
            //code here
        }
}```
Okay thats ridiculous

[swift crag]

The object isn't getting magically destroyed

it's just being removed from the list

element remains exactly as valid as it was before removing something from the list

[gloomy cosmos]

well the error implies that it does not, somehow

[naive pawn]

@rich ice

[naive pawn]

the error doesn't imply that at all

[slender nymph]

#💻┃code-beginner message

[swift crag]

I can assure you that you're not correct!

[gloomy cosmos]

swapping the two in order (removing and calling) fixes the problem

[swift crag]

Yes, because you're accessing List[i]

[naive pawn]

of course it does, but task isn't relevant, tasks[i] is

[rich ice]

i am aware, i just have to right it out a lot

[gloomy cosmos]

wait

[rich ice]

yoink

[gloomy cosmos]

I just realizes List[i] was used in there, I am so silly for noticing earlier

[naive pawn]

...we told you bruh

[slender nymph]

which is precisely why i asked you to confirm which line the exception was thrown on

[gloomy cosmos]

I swear it said the line before the actual one

[cosmic dagger]

this is the culprit: tasks[i].TimeToRun); . . .

[rich ice]

*i actually didn't know you could do that *

[gloomy cosmos]

anyway now its fixed, thanks a lot people, (I really do feel stupid tho lol)

[naive pawn]

(please don't, assignment expressions are such a pain to read)

[verbal dome]

Yeah don't

[swift crag]

t += t += t += t += Time.deltaTime;

let's goooo

[rich ice]

g u h

[swift crag]

this code is bad because it is framerate dependent! ✨

nothing else wrong here, no sir

[rich ice]

i didn't know you could do that either

[swift crag]

there's a line from Jurassic Park that comes to mind

and it's not the one about how smart the dinosaur is

[rich ice]

i've never watched jurrasic park

[naive pawn]

so... this adds dT and then octuples the result

[swift crag]

yeah

for MAXIMUM time

[naive pawn]

i hate you so much right now

[swift crag]

t = t++;

[naive pawn]

noop in plain sight

[swift crag]

your IDE will probably correctly determine that this doesn't do anything

[naive pawn]

may your ide forgive you because i sure won't [racks shotgun]

[rich ice]

        t += t *= t -= t += - Time.deltaTime;

finally, readable code

[untold shore]

Hey boxfriend, don't know if you're still in the chat, but wanted to thank you for the help for the past couple of days. Helped so much, and finally got it to work out!

[frigid sapphire]

Hey, I'm making a clicker at the moment and I am trying to make some sort of golden waffle flying aroudn that you have to click for some extra cash, when it was forced to spawn in 1 place it would work but when i added that it spawns in a random spot on the canvas it stopped spawning at all (can't even see it on the list of objects), debug log still says spawned but its nowhere to be found https://paste.ofcode.org/nFTZq92TJGHhPsQqCN5X9U

[naive pawn]

wow why is it not formatted at all

[slender nymph]

tab key machine broke

[frigid sapphire]

Who needs that anyway

[naive pawn]

you don't even need to tab to format stuff

it just happens

[frigid sapphire]

And I remove it:)

[naive pawn]

why are you starting Chance every physics tick

[naive pawn]

why do you hate yourself and everyone here

[frigid sapphire]

While loop caused some problems earlier so I changed it

[slender nymph]

your while loop should just be in the coroutine which could then just be started in Start instead of every 0.02 seconds

your yield break and yield return null are also pointless because they don't do anything after they yield

as for why it doesn't show up, instead of spawning the object up to 900 units away from the origin in world space then setting it's parent to the canvas, spawn it as a child of the canvas immediately

[frigid sapphire]

Oh god I thought I have to use either for the enumerator to end

[naive pawn]

you aren't yielding the WaitForSeconds so you're spawning it and immediately destroying it

[stable shoal]

Can someone please help me?
For some reason my player doesn't jump, even though in the debug, I added debug.log to show when the space button is being pressed, and it shows it but I don't know why it doesn't jump.

I can provide my code, a screenshot of the interface.
also I'm using a camera holder which maybe is the problem

[slender nymph]

just noticed that too lol. so there's literally no waiting happening

[frigid sapphire]

Oh I didin't notice that

[naive pawn]

you're leaving out a lot of information here

[naive pawn]

format your code

[slender nymph]

you will need to provide the code. #854851968446365696 has guidelines on what to include when asking for help. don't force everyone else to ask you to provide the information you intentionally withheld

[stable shoal]

Ok. thank you

how can I paste it in a way that it will not look like a lot of text, but rather as a formated code

[charred heart]

I'm facing an issue where an anonymous function passed as a parameter become null, but the value 5 (another parameter) works as expected.

private void Update() 
{
    if (Input.GetKeyDown(KeyCode.F))
    {
        _objectDetected.Interact(() => {
            _isInteracting = false;
        }, 5);
    }
}

// objectDetected
public override void Interact(Action action, int a)
{
    Debug.Log(action);   // this become null
    Debug.Log(a);        // and this still 5
}

you didn't save the paste

[slender nymph]

unless you are calling that method elsewhere and passing null explicitly to that parameter there is no reason it should be null. what does the log actually print

[verbal dome]

What exactly does the first log show? Just empty?

[stable shoal]

oops

[stable shoal]

Yea, sorry

https://paste.mod.gg/sdpadgnczxob/0

Does it work now?

[slender nymph]

wait nvm i read it wrong

[naive pawn]

so you're getting the Jump Key Pressed log, but not the Jump Triggered log?

[stable shoal]

Ohh wait, It shows me the cooldown and the state of "Grounded"
I dont think it's working

[frigid sapphire]

Got the waffle to spawn now (thanks Chris) but after a few times it just spawns outside the canvas even tho the Vector3 is set to the corners of it

[naive pawn]

you never reduce the cooldown or reset readyToJump

[naive pawn]

see boxfriend's message

[charred heart]

Here are the references, i call it twice with (null,1) and (anonymous function,5) and last one is the base class definition

[stable shoal]

do you think that is the problem?
I can try that out!!

[slender nymph]

i call it twice with (null,1)
so you explicitly pass null and it prints that it's null? so what's the problem?

[naive pawn]

ah wait i see you're setting the cooldown, nvm on that

[charred heart]

the (null,1) works as intended but the (action,5) become (null,5)

[naive pawn]

but you never reset readyToJump, still

[slender nymph]

show what it actually prints.

[stable shoal]

can I do this?

private void reset_jump()
{
readyToJump = true;
}

[naive pawn]

what does readyToJump even mean
you already have cooldown and grounded checks

[stable shoal]

It's for checking the state of the jump and if the "Player" can jump or not

[naive pawn]

what defines if a player can jump or not

[stable shoal]

I dont think that even If I will delete that, then it will work

[stable shoal]

if he is on the ground and the cooldown has passed

[naive pawn]

ok, so that's handled by grounded and jumpCooldownTimer

what does readyToJump do then

[stable shoal]

So it doesn't do anything

[naive pawn]

exactly

[cosmic dagger]

in what order do these calls happen?

[stable shoal]

I removed it

I have no Idea why it's not jumping

[naive pawn]

well look at your logs

are the 3 conditions met?

[stable shoal]

It did show the player velocity this time, but it showed this

[naive pawn]

and your player is on the ground?

[stable shoal]

what all the 0 means?
that It's probably a problem in the jumping function?

[naive pawn]

player velocity isn't relevant here

that's a postcondition, what comes after the action

what you need to focus on are the preconditions

Input.GetKeyDown(jumpKey), grounded, jumpCooldownTimer <= 0f

so the input and cooldown work

is your player on the ground in that screenshot?

[stable shoal]

no, but when starting the game he is falling down

[charred heart]

I ran the game again and encountered another bug. I will fix this first. The print result here

[naive pawn]

....ok, so you have other issues

[cosmic dagger]

those look like the two null calls you mentioned . . .

[naive pawn]

where's the 5 from the call with a non-null action

[stable shoal]

not falling through the ground

falling from the air to the ground

[naive pawn]

ah ok

so have you set playerHeight and whatIsGround appropriately

[charred heart]

I checked before coming here, and there was a 5, but now it's gone. Let me check again. Thanks everyone for the help 🤯

[stable shoal]

yep
player height is 2 in capsule collision, 3 in general and in the code it's 3 as well

[frigid sapphire]

I have tried a lot of things but the y pos of the waffle says -717 and the random is capped at -350

[naive pawn]

what's your current code

[naive pawn]

ok and have you set the other thing i mentioned

[stable shoal]

yes

[frigid sapphire]

not formatted yet but https://paste.ofcode.org/Sziap9dVuNfP996FtqphFw

[naive pawn]

there's probably a button in your ide to autoformat your code

[naive pawn]

have you set it correctly to whatever layer the ground is

[stable shoal]

yes, the ground layer is
whatIsGround

[frigid sapphire]

Oh yeah it was shift alt f

Shouldn't hurt as much now

[naive pawn]

thank you

[naive pawn]

where are you looking? the inspector?

[frigid sapphire]

yep

[stable shoal]

Chris what do you think I should do?

[naive pawn]

that's gonna be the relative position, but transform.position is the worldspace position

[frigid sapphire]

So how could I get the worldspace pos of the canvas edges?

[naive pawn]

it'd just be the position of the canvas

but you can just assign to localPosition instead

[frigid sapphire]

Alr i will try that

[naive pawn]

could try debugging the raycast to see if it's actually long enough

[frigid sapphire]

Tysm that worked

[stable shoal]

I dont know what to do anymore

It doesn't even show that it went to the jump method

[naive pawn]

right, because the conditions aren't fulfilled

you need to debug why grounded is false right now

[stable shoal]

sure

I will try to figure out why

this is to check the grounded

grounded = Physics.Raycast(transform.position, Vector3.down, playerHeight * 0.5f + 0.3f, whatIsGround);
Is this good?

[frigid sapphire]

me again, I'm getting the error "The name 'ggg' does not exist in the current context" it's an Instantiated game object and I'm trying to Destroy it when pressing the button using a function https://paste.ofcode.org/H55FhtnnpyY85N9TFbFkWR

[polar acorn]

There is nothing called ggg in the MoneyGoBig function

[frigid sapphire]

Is it possible to pass it from the enumerator to the function?

[modest dust]

Yes, make it a class-level field

Not a local variable

[polar acorn]

If you store it in a field variable, whenever you call MoneyGoBig, that would destroy the most recent object that ggg refers to

There's a missing piece here: What calls MoneyGoBig and when

[frigid sapphire]

The prefab button

When clicked it's supposed to destroy itself

But the script is on another game object

[frigid sapphire]

Wouldn't I have to drag and drop then?

[modest dust]

Why not just Destroy(gameObject) then

[polar acorn]

So if it's supposed to destroy itself, you should have a script on that object

Why is an object sending a message to a different object to destroy itself?

That'd be like me writing a letter to someone in another town to come and bring me a coke from my own fridge

[frigid sapphire]

To be fair I forgot I could even do that since I don't really understand prefabs

I will try that

[polar acorn]

A prefab is just an object that exists as a file instead of in a scene

[modest dust]

A prefab is the same thing you have in your scene, just existing as a file instead, to be instantiated in any scene

[gleaming turtle]

Is there inherently anything wrong with this code?
It's causing seriously glitchy behaviour with my projectiles but i haven't the slightest on how to fix it

    void FixedUpdate()
    {
        if (rb.linearVelocity.magnitude > 1.1f)
        {
            transform.forward = rb.linearVelocity;
        }

    ```}

[polar acorn]

What is the "glitchy behavior" it is having?

[gleaming turtle]

whenever i throw my projectile spear, it will orientate itself correctly to follow the head however whenever it lands & begins colliding with the floor, it then spazms out & teleports all over the floor, i have a clip but it's too big to post, i can share a google drive link.

[swift crag]

This might wind up causing the spear to clip into the floor

which will then make it go flying

[gleaming turtle]

hmm so it might be just because the spear is glitching in the floor?

https://drive.google.com/file/d/1N4cQVfAUL7piq8M7ifQczg_XiG6Bdgkj/view?usp=sharing

Here is a clip of the issue

[verbal dome]

Don't use transform when dealing with rigidbody objects.
Either try setting the rigidbody's centerOfMass to the tip (or even a bit futher) or use torque to rotate it

The center of mass solution should be "realistic"

If you manually rotate it, I'd also add a speed limit below which it will not rotate

[gleaming turtle]

i have tried this, nothing worked for me. I've managed to get it sorted now with one line of code & suddenly it works perfectly

transform.forward = Vector3.Lerp(transform.forward, rb.linearVelocity, Time.deltaTime * 0.25f);```

[swift crag]

I guess that'll prevent it from very rapidly turning

[gleaming turtle]

it seems to have done the trick, been playing around with it for a while now & hasn't broken at all yet

[tiny wind]

how do I fix this? Im trying to access CanAtk from another script, but it wont let me

[wintry quarry]

It says because of the protection level

You made it private

[tiny wind]

oh, I did not follow the tutorial correctly

ight thanks

[slate haven]

I want to make a game like this, if you can notice the blocks above look 3D, so like shall i make a 2D project or a 3D project?

[crimson pike]

2d

[teal viper]

Or 3d

[crimson pike]

you can pull it off either way really

[frosty hound]

The fact there are real time shadows in this, use 3D.

[scenic saffron]

how do I get the ground that a wheel Collider is colliding with

[slate haven]

Also, the clickable/interactable elemts look 2D, so I can use them in UI, and create a 3D project as well, right?

[scenic saffron]

yes

[slate haven]

Basically you have to select slots and the slots can shoot the front row blocks if they match the same color

[scenic saffron]

yeah you can do that with UI

[slate haven]

yeah

[teal viper]

These can be world space ui, sprite renders or even just mesh renderers. Just because it looks like ui or 2d, doesn't mean that you need a 2d template for it.

[slate haven]

yeah true, so its safe to start with 3D

[teal viper]

Yes. And you can always configure it to the same state as a 2d template.
The templates are just starting config/settings. Nothing that you can't change later on

[slate haven]

okay, thanks!

so how do I start? like a grid system is needed for this game?

[teal viper]

That could be one way, yeah.

[slate haven]

I mean im approaching a game like this the first time

[teal viper]

Maybe look up tutorials on similar games/mechanics

[slate haven]

Yeah

[scenic saffron]

so how do I do that?

[teal viper]

But basically break it down. The top grid could be just an empty game ojbect with a script that instantiates the blocks in ordered fashion and controls them if needed.

[teal viper]

Did you look at the docs?

[slate haven]

yeah, thanks

[tiny wind]

how do I make this a chain(sorry if its not the right term, if there is one)? like if I press left click, it will trigger Attack, and if I press right click within a certain timeframe after I trigger attack, its triggers Attack2

    private void Update()
    {
        if (Input.GetMouseButton(0) && cooldownTimer > attackCooldown && playerMovement.CanAtk())
        {
            Attack();
        }
        if (Input.GetMouseButton(3) && cooldownTimer > attackCooldown && playerMovement.CanAtk())
        {
            Attack2();
        }
        if (Input.GetMouseButton(2) && cooldownTimer > attackCooldown && playerMovement.CanAtk())
        {
            Attack3();
        }
        cooldownTimer += Time.deltaTime;
    }

    private void Attack()
    {
        anim.SetTrigger("attack");
        cooldownTimer = 0;
    }
    private void Attack2()
    {
        anim.SetTrigger("attack2");
        cooldownTimer = 0;
    }
    private void Attack3()
    {
        anim.SetTrigger("attack3");
        cooldownTimer = 0;
    }
}

[rich adder]

use some type of integer track which attack you're in, not even needed to have so many seperate methods

[slate haven]

how do i manage the background (being 2D) and putting 3D blocks in the same 3D scene? Please someone explain I am new to this type of style

[languid spire]

not a code question - #🔎┃find-a-channel

[untold shore]

Weird issue I'm having. Currently, I call on a button and it does what its supposed to do, but after I press another button, the first button acts like the 2nd? It's weird, and I can't figure out the function thats causing it when I press the button, since it works before I press the 2nd button. If it helps, here is the code that acts on the 2nd button press and repeats on 1st:
https://paste.ofcode.org/YFvpGrFgxKUvScSdnGNxYn . Any ideas of what's causing it? I've never had this problem before, and absolutely can't figure out WHY it's changing the first button function. (Please @ me if you respond)

Crap that code is probably a little long, moving it to a pasteofcode...

[spring coral]

so the intended behaviour is that you want to:
deal card
stand
deal card

but whats happening is
deal card
stand
stand

is that whats happening?

[untold shore]

Yep, and I don't know why it's switching over since I'm clicking the original button

[spring coral]

how are you assigning the function call to the button?

are you doing it via unity events in inspector or manually assigned in code via button.onclick.AddListener?

[untold shore]

Unity events in inspector

[spring coral]

do they both call separate functions?

or is it the same one with a different param or something

[untold shore]

They do, they're entirely separate. Most I can think of is they are on the same script, but I don't get why it would call a different function. I'll show you a quick photo of both button function calls:

[spring coral]

send me the full script for deckmanager and dealerdeckmanager

throw it in a pasteofcode or something

[untold shore]

Gotta:
Deckmanager: https://paste.ofcode.org/34N6sMtLaLTaKHtUJuwUVCc
DealerDeckManager: https://paste.ofcode.org/cUH4ECsFZ8YgYT9F9qsuNP

[spring coral]

nothing suspicious here?

when the issue happenns, click on the "resetting player hand" log under ResetPlayerHand and send then stacktrace screenshot here

specifically this after clicking on the log

[untold shore]

I don't know why it would do MoveNext()

[spring coral]

is that the full stacktrace or is there more if you scroll down

[untold shore]

Thats it

[spring coral]

also MoveNext is just because fo the coroutine

better yet, throw a debug.log under ResetPlayerHandVoid

something is calling that coroutine and because its under a coroutine its not sending the source call

so just throw a log in there and try again

[untold shore]

Yeah, it's not even calling ResetPlayerHandVoid, it's just moving straight to the ienumator, which is really weird

[spring coral]

the yield return null means that something at least a frame before is calling the method

what are all of the things that can cal ResetPlayerHandVoid?

is it just the buttons?

[untold shore]

It's only these two, which are only called when the deckmanager or dealerdeckmanager call for them. the buttons just start the things that call these two methods

[spring coral]

and youre saying that even when you put a log in ResetPlayerHandVoid nothing comes up when you click on deal?

[untold shore]

Yeah, Here Ill get a quick video to show you the entire logs

[spring coral]

sure

[untold shore]

Alright, finally got it to show up the ResetPlayerHandVoid comment, maybe it was just slow. I think it's something with DealerDeckManager. Currently gonna try it out...

it was the stupid variable. playerstands, I never turned it back to 0. Ugh! So happy you helped me with that though, I NEVER would've figured that out. Finally going to go get some rest. Again, thank you!

[spring coral]

nice, and np!

[regal kettle]

Why is this code uncreachable?

[rich adder]

because you are returning

[regal kettle]

ima ctually so stupid

[rich adder]

code runs each line top to bottom

[regal kettle]

I'm sorry the easiest things always miss me

[rich adder]

also is there a reason you're doing this instead of just using Keycode ?

[regal kettle]

not in particular

but I'll try thgat

wait yeah I want to get the input not just a keycode

[rich adder]

wdym the input ? GetKey gets inputs

[regal kettle]

doesnt getkey return a bool

[rich adder]

yeah checks if ur holding the button

[regal kettle]

im trying to make sure that the button that is pressed is the same as the letter

does input.inputstring not suffice?

[rich adder]

which letter?

on the keyboard?

[regal kettle]

I currently have one M key

and im trying to make it so that only when I press m it changes sprite

is released is supposed to chjange sprite of the key to fgray

this is where I use checkkey

[rich adder]

are you pressing these on the keyboard or the mouse ?

[regal kettle]

keyboiard

[rich adder]

Input.GetKeyUp gives you when certain key was released

[regal kettle]

I have a quick nonrelated question

in a case like this m is a child of keys and keys is a child of keyboard correct?

[rich adder]

yes

[regal kettle]

is this the wrong approach?

[rich adder]

looks overconvoluted, I still don't know what you want you're going for tbh

[regal kettle]

Ok so

[rich adder]

you just want to change sprite according to keypress?

[regal kettle]

Im trying to make an on screen keyboard

with all keys of course

then when I press it

it turns to another sprite

[rich adder]

so not when you use keyboard like you said before

they are UI buttons ?

[regal kettle]

sprry i meant when I press the corresponding key

it changes sprite to a pressed down one

[rich adder]

is Key a custom class?

[regal kettle]

yes

So in this i made checkkey ourput hello in the debug log and made ispressed output lol in the debug log

but there is hello in the debug log but not a bye

[rich adder]

I would do it a bit different

[regal kettle]

how?

[rich adder]

Make it clear if Key is the UI button / key. if it is store the char in there

[regal kettle]

Key is the highlighted gameobject and it is the M key on screen

[rich adder]

are you going to manually create these? that painful lol

[regal kettle]

well how else would I do it lolo

[rich adder]

store the chars in an array , iterate through array instantiate a UI button and assign it the char

[regal kettle]

Im not good enough for that lol

[rich adder]

you should probably be starting with a simpler project

[regal kettle]

Yeah I should ahve

but its scdhool so what can I do

[rich adder]

make it simpler?

[regal kettle]

I dont know how

also complexity is a part of the rubric as well

[rich adder]

so you're telling me your school just throws you this project without any basic understanding of the thing you're supposed to do?

[regal kettle]

no I chose unity like an idiot

[rich adder]

so what is the assignment and why did you make it this complicated ?

[regal kettle]

IB computer science internal assessment

[rich adder]

how is that a specific project?

[regal kettle]

its not you make one up

look I made some mistakes but theyre not something I can fix now

[rich adder]

yeah so pick something simplified

like pong ?

[regal kettle]

Complexity is a criteria

i cant make pong and get a good score

[rich adder]

pong is still complex

trig math / physics / number tracking

[regal kettle]

Maybe thats true but I'd have to do all my previous work again for that

that'd be harder

[rich adder]

do as you wish, better than being stuck on a much more complex system / problem imo

I dont have the guarantee of my previous parts all being perfect scores

The code is only half of my grade and my teacher of course wont grade it again

What is it called when you use a single int to represent multiple pieces of information? For example a three digit int where the first two digits convey thing A and the last digit conveys thing B. I thought 'bitcode' but idk if that's right

or for example a hexcode where each int represents the state of a surrounding tile

And then what's the best practice for 'cutting out' certain digits (the part of the bitmask that's needed)? Have to convert to string?
