roblox is a pretty powerful engine imo its more of the recourses you have to use limit you a ton

[plucky kernel]

I remember seeing a 100 robux game would give me 10 robux in profits

[crimson pike]

That’s disgusting

Sheesh

[woeful bridge]

it use to be 0% of profits

lol

[plucky kernel]

WOW

[frosty hound]

This isn't a Roblox server, keep this channel on topic please.

[grand snow]

there is a great video series of the exploitive nature of roblox games

ops

[woeful bridge]

scary man appears D:

[plucky kernel]

I knew this would happen

[woeful bridge]

[crimson pike]

so how do I script the code to make an mmo

[woeful bridge]

you type things

and put some magic in your words

then boom mmo

[plucky kernel]

alright so my unity question that I had written somewhere else

[crimson pike]

(Something rest of the owl)

[plucky kernel]

omg it's too long

[woeful bridge]

HOLY SHIT DEACTIVATING A OBJECT MAKES THE SCRIPT NOT RUN ITS A FUCKING CHRISTMAS MIREACLE

Ok back to my slave shift on programming

[polar acorn]

That is literally the definition of deactivating yes

[woeful bridge]

you should tell roblox that then

anyways I'm gonna code

[ivory bobcat]

The callback methods are disabled, yes.

[woeful bridge]

for like an hour thanks for the yap and talk and help

[crimson pike]

Which script to deactivate to make an mmo

[woeful bridge]

system32

[polar acorn]

Another symptom of the object itself not actually running the code

[teal viper]

Just to make it clear, it only stops unity messages/callbacks. Code that you call manually on the script will still run(obviously).

[crimson pike]

Oh really?

[woeful bridge]

kk

[crimson pike]

Will a method finish executing if a script sets its game object to inactive in the middle of the method?

[woeful bridge]

woah thats insane it stops everything when you disable a object unity is so fucking cool

[ivory bobcat]

Reminder that setting an object inactive and disabling a component are two different things.

[teal viper]

Yes. You can't stop method execution from outside the method.

[woeful bridge]

I meant the entire object

[ivory bobcat]

Both which may share behaviors though

[crimson pike]

Huh. Good to know

[polar acorn]

Once a method is called, it will run to completion until it hits a return statement or an error. Nothing else in the entire project can happen until one of those things occurs

[woeful bridge]

You can’t kill a entire thread?

[crimson pike]

Unity’s got so many quirks to navigate

[polar acorn]

You can, but since Unity is single-threaded, killing the thread will kill the entire program

[woeful bridge]

Huh weird

That functionality was within my old engine and it was also single threaded

[teal viper]

I don't think there's such a thing as "kill a thread". You can join threads, but the thread needs to stop it's execution. You can kill a process, but that's a different thing entirely.

[crimson pike]

You can do thread pooling still tho right?

[woeful bridge]

Maybe I meant process

[crimson pike]

Like native c# multi threading tools work the way I’d expect?

[polar acorn]

Yes, but you can't run any UnityEngine functions outside the main thread

[crimson pike]

And that was my next question. Ic

So it’s only useful for background logic jobs or async asset loading?

[woeful bridge]

So I’m confused within my old engine I was able to create virtual threads then kill them is that not a thing for unity?

[polar acorn]

Basically.

[polar acorn]

As I said, you can still write multithreaded code, but UnityEngine functions are only available on the main thread

But Unity does provide Coroutines for psuedo-asynchronous code

It's not actually multithreaded, it just pretends to be

[teal viper]

What was the actual implementation? Share the code.

[woeful bridge]

Yields pretty much

I can show the docs ig

[crimson pike]

I could make a background data logger that sends http requests to a remote server tho yea?

[teal viper]

I mean of the "thread killing" functionality.

[crimson pike]

Like I guess you’d have to read all the game data in the engine and pass it off to the background remote logger job or something

[woeful bridge]

I FOUND THE WORD

coroutine

THAT

[grand snow]

Unity is not "single threaded" purely but the core update cycle logic is single threaded and ofc most user code will be too

[woeful bridge]

Is that a thing on unity

[wintry quarry]

yes

unity has coroutines

[woeful bridge]

Ok

[grand snow]

Coroutines 🙂
async 😎

[crimson pike]

What was their purpose in rbl

Oh

[woeful bridge]

Killing virtual threads

[crimson pike]

So what about InstantiateAsync is there a practical use for that?

[teal viper]

It might be a totally different thing if it's a different engine and even more so if it's different language. But it doesn't sound like a feature built in into the language, so the "thread killing" probably has some more complexity to it than you understand.

[grand snow]

last time i tried instantiate async it was half broken 😆

[woeful bridge]

Idk docs just says it suspends the thread I assume thats killing it no?

[crimson pike]

I couldn’t find any perceivable difference besides it taking like .01 Ms to finish

[wintry quarry]

That's actually not possible because no other code would be running during a method.

and you cannot disable a component outside the main thread

[teal viper]

It could. But that doesn't mean it would stop right in the middle of the method execution. It's likely gonna suspend when it returns to the thread root and would be joined with the main thread.

[crimson pike]

Ah I meant something else with that and mainly just a curiosity

You actually cannot just "kill" a thread in new .net anymore, now you need to use cancellaton tokens:
https://learn.microsoft.com/en-us/dotnet/standard/threading/destroying-threads

[woeful bridge]

It does if I have a yield in it but that could be because the yield is part of the dane library idk

Or I don’t understand that in-depth of code idfk

Was just curious tho thanks

[crimson pike]

public void DoSomething() {
     this.someComponent.DoAnotherThing();
this.gameObject.SetActive(false);
this.someComponent.DoYetAnotherThing();  //does this happen?
}

[grand snow]

yes

enable state controls if some functions like Update() are called and thats about it for monos

ofc for say a renderer, it wont render anymore

Up to you to check the enabled state if you want it to be used!

[teal viper]

There's probably some system moving behind the scenes that actually handles the thread correctly, but for a user of the API it just seems like the thread is "killed".

[polar acorn]

yes

[woeful bridge]

I’m sure lol theres no way to see behind the scenes on that platform so I have no idea

[wintry quarry]

Yep, absolutely. Code will always run to completion unless there's an exception

[crimson pike]

Yeah that’s what I was asking 🙂

[woeful bridge]

But yeah thanks!

[crimson pike]

Cool

[polar acorn]

Disabling an object only prevents Unity from calling a function. If you do it manually it works. Otherwise, you'd never be able to activate it

[crimson pike]

Though I don’t see a practical reason to structure code in a way it could step on its own toes but good to know

[wintry quarry]

Active/enabled is really about if Unity engine is going to run your code. It's basically meaningless outside of that from a code perspective

[grand snow]

Awake() is always called even if disabled and ofc user code can do whatever

[crimson pike]

Well, I mean it clearly is intended to be an easy way to strike objects from a scene without destroying them

[wintry quarry]

Awake doesn't run on disabled scripts actually until they get enabled for the first time

[grand snow]

that should be start no?

[wintry quarry]

Nope, both of them

[crimson pike]

What’s the Diff between awake and start?

[wintry quarry]

Ah active object vs disabled component yeah

[teal viper]

Script != Gameobject

[polar acorn]

A disabled component of an active game object

[teal viper]

Enabled != Acitve

[grand snow]

yea i mean the components disable state

[polar acorn]

If the object is disabled, the scripts don't run awake

[grand snow]

I kinda wish that wasnt the case myself but yes

[polar acorn]

I think we've been kind of loosey goosey with the words "enabled" and "active" this whole conversation

because there is a very important difference

[crimson pike]

Also I’m assuming trying to access components in a constructor is not gonna work right

[wintry quarry]

Weird question

[grand snow]

nah it moans at you usually for being too early

[wintry quarry]

Generally you shouldn't have a constructor if it's a MonoBehaviour at all

[polar acorn]

You shouldn't have a constructor for any sort of component at all

[wintry quarry]

You should use awake

If it's a regular C# class then you can do whatever you like in the constructor

[crimson pike]

I’ve only been using constructor to instantiate things like lists

With a : base() just in case

[wintry quarry]

Use awake or the field initializer

Not a constructor

[polar acorn]

if it's a monobehaviour, you should not use constructors. They won't run

[wintry quarry]

If this is a MonoBehaviour

[polar acorn]

Chances are you have serialized the lists so they're created by the inspector and you've never noticed those functions don't run at all

[crimson pike]

Yeah, I mean it does work but I was only making sure the list isn’t null at runtime

Nothing more complicated than that. But probably better get out of that habit for unity

Sorry for weird questions still getting my head around how unity thinks in general

[teal viper]

You should initialize your fields with field initializers or in awake in MonoBehaviours

[crimson pike]

So awake is like unity’s pipeline constructor? What differs between that and Start()?

[grand snow]

img i sent before, awake is called even if the component is not enabled

[crimson pike]

Oh thanks didn’t see it

[grand snow]

start gets called first time it is enabled (usually the case)

[teal viper]

You can see the whole lifecycle of a MonoBehaviour here:
https://docs.unity3d.com/6000.0/Documentation/Manual/execution-order.html

Constructor is reserved by unity and is called somewhere before this.

[crimson pike]

Neat

[grand snow]

i need that image as a poster

[polar acorn]

Awake runs immediately. Start runs before the first Update loop an object exists for

If you spawn an object in code, that object's Awake method will run before Instantiate returns. Start will run after the current Update frame is done

[grand snow]

Dunno if common but 99% of what I write has manual Init() functions that we use (usually also to pass some dependencies too)

[polar acorn]

That's not an uncommon pattern. Sometimes you need something that runs between Awake and Start (like if you're instantiating multiple things and need them to reference each other)

[swift crag]

I've moved more and more towards this

especially for objects with an obvious owner

[woeful bridge]

can you make custom properties in a object without like making a script?

Like I wanna some how just have a refrence to another object in the object

but do I really need a whole script to do that

[wintry quarry]

yes

you need a script for that

[woeful bridge]

☹️

kk

[wintry quarry]

You could also have another script that stores a dictionary that holds the data but... that's a script

[woeful bridge]

yeah just having a refrence is easier

[wintry quarry]

It's really not a big deal to have a script

[woeful bridge]

ik

[wintry quarry]

beginners often use way too few scripts

[polar acorn]

What would you even do with a reference without having a script to do anything with it?

[woeful bridge]

I just need to tell the game what item in my character thats inactive to activate when I pick up an item

so I legit just need to get that refrence and activate the object then destroy the object on the ground

[wintry quarry]

sounds like a perfect little single-purpose script

[woeful bridge]

Yeah! I was just being sure there wasn't a different way

[wintry quarry]

really this is one script on the player - the interaction script
and one script on the object - that has the info about which item to activate on the player.

Really it could be a prefab reference to instantiate too

there are many ways to do everything and anything

[woeful bridge]

I know I'm just coming from a different engine so I'm trying to figure out the traditional way to do things before I make my own ways

like the way I would do it in the other engine is the heiarchy is a big ass dictionary table so I'd just grab the name and get the child with the name lol but I think with unity its a big ass array

or list idk

[wintry quarry]

You could do the same in Unity but really that's a very inefficient way to do things

unity has much more efficient ways

[woeful bridge]

ye thats why I asked

[polar acorn]

And you should never tie functionality to names. If you decide later you wanna capitalize something suddenly all your inventory system stops working

[woeful bridge]

like I said I didn't have a choice in the previous engine so I kinda had too I'm mindsetted in one engine and now I'm trying to swap my mindset to a new engine

its why I'm asking questions that might sounds dumb lol

[hallow bough]

So I am working on exporting my project thorugh WebGL, but when I run the game outside of the editor, the screen zooms in a wierd manner, and the button for changing the scene does not work. Can anyone help?

{
    ClosePhidgets();
    SceneManager.LoadScene("Scene1");
    StartCoroutine(WaitForSceneLoad(SceneManager.GetSceneByName("Scene1")));
}

public IEnumerator WaitForSceneLoad(Scene scene)
{
while (!scene.isLoaded)
{
    yield return null;
}
Debug.Log("Setting active scene..");
SceneManager.SetActiveScene(scene);
}

private void ClosePhidgets()
{
    redButton.OnApplicationQuit();
    ui.OnApplicationQuit();
}```

ps. I know start is not capitalised, it is the name of a button

[wintry quarry]

As for the scene button not working - check the browser console window for errors

Also make sure the button is responding to mouseover.

[hallow bough]

there is a browser console? where is that?

[wintry quarry]

of course...

depends which browser you're using

[hallow bough]

sorry...

[wintry quarry]

For chrome

I take it you don't know anything about web development then

Thje size of the game window is determined by the HTML/CSS on the page

[hallow bough]

definetly not, this is my first ever coding project outside of block code

[wintry quarry]

specifically of the html canvas element the game is being drawn in

https://www.w3schools.com/html/html5_canvas.asp

this is strictly a web development concern

there's nothing Unity can do to control this

you control this with your HTML/CSS/Javascript on the web page

Note that by making a webgl game you are essentially committing to making a small, simple web page as well.

[hallow bough]

is there a better alternative? my goal is to get it to run on a raspberry pi

[wintry quarry]

the unity build will give you basically a barebones sample web page

but you can and should customize it

[wintry quarry]

Why build for webgl then and not as a linux desktop app?

If it's webgl, it runs in a web browser

[hallow bough]

how should I do that? I am running unity on a windows computer, so I assumed I would not be able to interact with unity

[wintry quarry]

How do you do what? Make a linux build?

[hallow bough]

yes

[wintry quarry]

https://docs.unity3d.com/6000.0/Documentation/Manual/build-for-linux.html

[hallow bough]

ty ❤️

[teal viper]

I wonder if raspberry pi is a compatible device at all.

[hallow bough]

what do you mean? for WebGL?

[teal viper]

Though I guess if it runs in the browser, it should be fine as a standalone build too.

[teal viper]

In general.

[hallow bough]

how big would a linux build be? I have 8 gb and I am curious if it takes more (it is a decently small project with 2 scenes)

[wintry quarry]

It depends heavily on the content of the game. The number of scenes is not that important. Usually the biggest driver of the build size is the multimedia assets like textures and sounds.

The minimum build size with a completely empty project and basically all assets and packages removed is probably around 5MB

[hallow bough]

which linux module should I use? I saw these three and I am not sure of the distance

[teal viper]

Mono or il2cpp

Or both just in case you want to test both builds

[hallow bough]

is one of them better than the other? I have limited storage and processing power, so I do not want to waste space

[wintry quarry]

the first one generally

[dense mica]

Hey folks, over the years I've periodically had issues with Unity Editor Run performance while running my games. This past month it has gotten really bad, where things will freeze up for seconds on a 7800X3D w/ 4080 super just running a simple 2D game. The profiler is showing long waits like this. I've been messing with Gsync and other settings to no avail. Compiling/running my game gets 200+ fps without any issues, so this all appears editor related. Any thoughts on what it might be?

[mighty compass]

Hey guys, I’m transforming a player model during update, rotating it during late update (because of animation priority), and setting a gun model’s transform and rotation to the player models hand during late update. I’m having an issue where the gun models position is not synced up with the player at all.

[sweet mica]

Why is it red?

[slender nymph]

you're missing the closing brace for the Update method

looks like maybe the one for the class as well

[sweet mica]

You are the goat, thank you

Does the moving code go in the blueprint or is it applied after it spawns?

[echo ruin]

What moving code?

Assuming you’re doing the flappy bird tutorial, moving code should go in the Pipe object

[sweet mica]

Do i have to make a new asset?

If i left it out

[echo ruin]

You already have the pipe object

Which I’m assuming you want to move?

[sweet mica]

Yeah, i made a sprite, then the tutorial said to make an asset with a top and bottom pipe, do i add the move script directly to the asset?

[echo ruin]

Wait okay. I think I know what you mean

You add it to the prefab

[rich adder]

if you're following a tutorial, follow the tutorial ?

[sweet mica]

I'm trying 😭

[echo ruin]

I.e. Blueprint. The thing you clicked and dragged into the folder

[sweet mica]

I forgot to drag and drop

Lol

[echo ruin]

If you put it on the prefab, it will be attached to all the objects that spawn. If you put it on an object in the hiearchy (the window where your objects are), it will only be attached to that one

[sweet mica]

Uh oh

Well at least they are moving

[echo ruin]

Does it work?

[sweet mica]

It's spawning 1, then a second later thousands

[echo ruin]

Did you put the spawner script on the pipe object?

[sweet mica]

Lemme check

[echo ruin]

Cause then each pipe will spawn more pipes lol

[sweet mica]

What do i need to screenshot?

[echo ruin]

The window you attached the script to

[sweet mica]

Tada

[echo ruin]

Okay all good

Now screenshot the hiearchy window.

[echo ruin]

Okay

Screenshot script again

Your updated script

[sweet mica]

You did mean the spawn script, right?

[echo ruin]

Yes

It looks right. Can you screenshot the pipe object window

Inspector window

[echo ruin]

That’s the spawner. Find the pipe prefab

Should be in a folder somewhere

[sweet mica]

Thats what i clicked on

The one with the blue cube

[echo ruin]

You’ve attached a Pipe object, but you’re looking at a PipeSpawn object

[sweet mica]

Oh i clicked and nothing happened mb

[echo ruin]

That looks like a prefab that contains more child objects

I want to see what components you have in the child objects (you should have an upper or lower pipe?)

[sweet mica]

The sprite itself? I just ctrl c > ctrl v'd and flipped it

That's what the tutorial said to do

[echo ruin]

But you should have an object containing the sprite renderer

[sweet mica]

This?

[echo ruin]

Oh wait

I see the error

In the spawner script, you’re not resetting the timer

[sweet mica]

Lemme check the video

[echo ruin]

You need to set the timer back to 0 in the spawnPipe method

Timer = 0;

Cause now, it will just keep spawning a pipe every frame once the timer is up

[ivory bobcat]

if(...)
{
    ...
}
else
{
    spawnPipe();
    Timer = 0f;
}```

[sweet mica]

Yeah I found it lol

Thanks

It's beautiful

[echo ruin]

Very nice!

[sweet mica]

I feel like a toddler learning the alphabet

[ivory bobcat]

I'm sure it was just as magnificent prior to fixing the cooldown timer 😏

[sweet mica]

Hardcore mode

Also, I noticed it takes a solid 10 seconds for the game to run, is there a way to make it go faster?

[swift elbow]

go to your project settings > editor and change the reload domain setting to reload scene only

[versed cove]

void Move()
    {
        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");

        Vector3 move = transform.right * x + transform.forward * z;
        controller.Move(move * speed * Time.deltaTime);

        isGrounded = controller.isGrounded;

        if (isGrounded && velocity.y < 0)
        {
            velocity.y = groundedGravity;
        }
        else
        {
            velocity.y += gravity * Time.deltaTime;
        }

        controller.Move(velocity * Time.deltaTime);
    }

    void Look()
    {
        float mouseX = Input.GetAxis("Mouse X") * lookSpeed;
        float mouseY = Input.GetAxis("Mouse Y") * lookSpeed;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        playerCamera.transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
        transform.Rotate(Vector3.up * mouseX);
    }```

Just need some advice on this, thoughts? Anything I can clean up or improve? Is this acceptable?

[sweet mica]

Thanks pookie

I added a box collider to the prefab and now the bird is flying backwards

[echo ruin]

When it flies into a pipe?

[sweet mica]

No it instantly goes offscreen to the left

[ivory bobcat]

Maybe the birdie is bumping into something in the scene.. for instance, the background

[echo ruin]

Sounds like the collider pushes the bird away

Did you attach the collider to the bird itself

[sweet mica]

I made the background through the main carmera though

Does it start with a collider?

[echo ruin]

I.e. The same object that has the rigidbody2D component?

[echo ruin]

It shouldn’t

[sweet mica]

The bird has a rigid body and a circle collider

[echo ruin]

Then what did you put the box collider on?

[sweet mica]

The pipe prefab

Is there a voice channel to share screens?

[echo ruin]

Colliders don’t automatically adjust their size and location to the object, so it might have spawned at the center of the screen

You have to adjust it manually

[sweet mica]

Oh, that makes sense

[echo ruin]

That would be best to do inside the prefab.. when you press the cube inside the asset folder

[teal viper]

No. But you can record a video instead.

[sweet mica]

True

[echo ruin]

Then on the box collider component, there should be a button with a bunch of lines and circles on it (i think). Click that so you can see the collider

Then you can easily adjust the borders of the collider by pressing and dragging on the x and y on the scale input

[sweet mica]

FOUND IT. FINALLY.

Thanks

It looks like this, right?

[echo ruin]

Yes

Then just fit the size to the pipe

You might need another box collider for the top pipe

[sweet mica]

The reason i couldn't find it is because i didn't have the actual pipe on the scene lmao

Can i delete it now?

I'm still flying backwards but faster now

[echo ruin]

Even when not near the pipe?

[sweet mica]

Why did it do that

Uh oh

[fickle plume]

@sweet mica Please create a thread.

[sweet mica]

Oops, sorry

The best flappybird game ever

[echo ruin]

I can’t watch that on my phone

[sweet mica]

I'll fix it, its going in the thread now

[slate haven]

How to jump with new input system but with using Transform.Translate and custom gravity? how do u do that

[hexed terrace]

Those are two separate unrelated things.
You just want to find out how to detect a key/button press with the new input system -> do basic tutorials (probably found in the pinned msg's on #🖱️┃input-system )
Once you've learnt that, all you do is call a method with it, in which you put whatever you need -> google unity how to jump

[slate haven]

i know how to use input system. What i was asking is how to implement custom gravity without using rigidbody

[burnt vapor]

You can create your own system which constantly adjusts assets based on gravity. You don't have to be tied to the build in system

With 2d games I generally just make it myself and a FixedUpdate method constantly pulls down objects based on the configured gravity

[slate haven]

got it

[dreamy gull]

Is there documentation for global-metadata.dat anywhere?

[fossil drum]

This smells like you want to reverse engineer someone else's game.
Why would you want documentation for something you can't change? Do you have a specific use case for this?

[dreamy gull]

It seems like a fun project to learn. That's all

[fossil drum]

Well the #📖┃code-of-conduct states that decompilation and modding is not a topic that's allowed on this server.

[dreamy gull]

Okay. What does that have to do with learning about file formats?

[burnt vapor]

Because why else would you want to learn about the file?

[dreamy gull]

Curiosity?

There's already tools to dump the data from the file.. I was just interested in the file format

[fossil drum]

So yeah, this is about decompilation.

[dreamy gull]

In what way?

[fossil drum]

I'm not going to argue semantics with you, good luck with it.

[dreamy gull]

I already found it. I was just looking for official documentation

[sharp sluice]

Doesn't unity generate that file

[keen owl]

A built project typically contains those, yes

[sharp sluice]

oh i'd reckon that this would be the place for asking about that stuff

[dreamy gull]

Wow. I was about to reply to the person asking why I would want to learn and they deleted their message v.v

ok

here is a code: https://paste.mod.gg/vifwubmpmdhd/0

so, why when i have Horizontal axis = -1, player rotates x rotation?

i didn't wanted to

[echo copper]

can describe a code: rotator1 is a rotator in front of player, rotator2 is a rotator behind player. They use rays for checking collision with ground and getting the collision point. I find an angle between these 2 points.

code should rotate only z and y rotation, but not x. it didn't suppose to do it.

is anyone here?

[grand snow]

do you have any other components that change the rotation? try debugging what the rotation is actually set to when going left

cus if thats all that sets rotation it must be it. working with eulers only can cause issues like this

no, i don't have other components that rotates player

log before/after to see what the rotation changes to or attach a debugger and see what happens @echo copper

[echo copper]

urm... i have never done this...

[grand snow]

time to learn! Debug.Log() is easy to start with and using a debugger is a powerful way to see what code is doing

[burnt vapor]

I decided I didn't care enough

[dreamy gull]

That's fair

I don't care anymore either

[burnt vapor]

🤝

[fossil drum]

Just FYI, you can get the same EulerAngle rotation by doing other rotations.
So your the value that you actually set with ANGLE on the Z axis and -180 on the Y is the same rotation as -180 0 -45.
So even if you don't set the X, Unity can simplify it to that itself.

[echo copper]

i don't know... should i use cos and sin?

anyone?

maaaaaan...

[languid spire]

that is not what @fossil drum said

[echo copper]

well, maybe i didn't understand him, sorry

[languid spire]

what is not to understand? -180 0 -45. is not 180 0 -45.

[echo copper]

for a debug...

[echo copper]

im a fool.

what should i do... i am really sorry if i am too annoying, but how to fix directions?

[tiny wind]

how do I put the scale of an object into the code?

[grand snow]

Id just rotate the main character parent for the slope angle and flip the model child separately via scale or rotation

or you do it in a different order.
Quaternion.Identity -> rotate y for left/right dir -> do slope x/z rotation

[rough lynx]

Change the localScale of a transform

[stray stump]

After destroying player just instantiate it and there is field for position, put vector3.zero into it. To instantiate you need player to be prefab. If you don't know what those things mean go to unity learn website do basic lessons.

[tiny wind]

how do I do this? im making it so that the if statement activates when the scale is that

this doesnt work, i just found out

[visual linden]

localScale is a Vector3, so you need to directly compare it as such, *
transform.localScale == new Vector3(1, 1, 1))

Alternatively, you can use Vector3.one, which is a shorthand

[tiny wind]

I get an error when I do that

[timber tide]

you're doing an inline assignment

[tiny wind]

what is that and what should I do?

[timber tide]

They gave you the hint already

[visual linden]

Comparison is ==

Single = is an assignment

[burnt vapor]

Assignments: =
Comparisons: ==

[timber tide]

I wonder why that is throwing an error anyway. Does that not work in c#

[tiny wind]

oh, did not notice, alr thanks

[visual linden]

It's in an if statement

[burnt vapor]

I believe inline assignments work as long as it returns the expected type

But that was not the intention here obviously

And if it did, it would have to return a boolean somehow

[rancid tinsel]

any idea why a script component might disable itself at runtime, despite there being no code telling it to?

https://paste.mod.gg/gboifliizloq/0 here is the code in question

[burnt vapor]

What about enabled?

[rancid tinsel]

is that in my script somewhere?

[burnt vapor]

No, I mean you look for the keyword enabled

Because setting this disables components

[rancid tinsel]

i get over 100 different results because of a package ive got

let me limit it

[astral falcon]

You rather should look into other scripts that probably do something GetComponentInChildren or so and enable/disable them

[rough lynx]

If your packages aren't in separate solutions you can also ctrl + shift + f and search your entire solution

[rancid tinsel]

the thing is i dont think ive added anything that enables/disables yet

those are the only instances of "enabled" in the entire solution

[teal viper]

Do you have errors in the console perhaps? When it disabled

[rancid tinsel]

yes i was about to ask if that could cause it

[teal viper]

It could be. Errors in Awake would disable the script for example.

[rancid tinsel]

ok seems that was it!

thank you

[teal viper]

Always pay attention to the errors in the console. They would often be the cause of whatever issues you might have or at least be related to them.

[echo copper]

can i... ask the same question again..? like... WHY IM TRYING TO ROTATE Y ROTATION, BUT IT ROTATES X ROTATION, IDK WHY

like. if i rotate: transform.rotation = Quaternion.Euler(new Vector3(0, 180, 0)); it rotates y rotation

if ANGLE = 0, he rotates x rotation, not y as it not supposed to be

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

but here, he rotates y rotation as it supposed to be

[teal viper]

You don't ever rotate around Y axis. Well aside from setting it to 180 degrees in the first snippet.

[echo copper]

ow... urm... and... how to rotate it right way?

[teal viper]

I suggest you check some tutorials and go over the beginner pathways on unity !learn:

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[teal viper]

Because it sounds like you're missing some basics.

[echo copper]

maybe, i am started to use unity clearly two month ago...

[teal viper]

Well, then you didn't learn properly. You should be able to rotate an object after a week or 2.

Assuming you learn properly

[willow shoal]

i have big problem because he everytime switch this to this after destroy : /

[rancid tinsel]

any idea why this never gets to the last line? no error, application still working I'm super confused

it does the if statement clearly because I get the "Number of words" debug

but then just ignores the last line

[burnt vapor]

Your question is very unclear so nobody is going to help you most likely. Please try to explain in better detail what the question is and make sure it's coding related.

[teal viper]

Which of the Number of words do you see in the console?

[rancid tinsel]

the "added to dictionary" one at the end

but both of them

[teal viper]

Okay, then what makes you think that it doesn't execute the last line?

[rancid tinsel]

i also added a debug after the last line and that didnt go through either

[burnt vapor]

Code doesn't just stop working for no reason. Your code most likely did reach the end, but you didn't notice it happening

I suggest you put a log above PopulateTrie to verify

[teal viper]

Are you sure you don't have errors? Take a screenshot of your whole console.

[willow shoal]

when my block spawn he change player form file to hierarchy

[teal viper]

Did you save and compile?

[willow shoal]

and i cant spawn 3rd time

[rancid tinsel]

yes

[burnt vapor]

What calls LoadWordList? Is it an asynchronous method?

[willow shoal]

my player stuck

[burnt vapor]

And also, share PopulateTrie please

[rancid tinsel]

they're just called like this based on what is needed, but those are then called like this

[teal viper]

Try restarting the IDE, or even the editor too. Sometimes code changes are not registered.

[rancid tinsel]

didnt work sadly

[rancid tinsel]

1 sec

[teal viper]

The editor doesn't freeze, right?

[rancid tinsel]

https://paste.mod.gg/atyuimxnxzex/0 thats the whole script with the PopulateTrie

[rancid tinsel]

no it just keeps working

[teal viper]

That's very weird. There should either be an error or a freeze(if it's stuck in that last line method).

It doesn't seem like threads are involved either

[teal viper]

Did you confirm that the code is up to date after restarting the ide/editor?

[rancid tinsel]

yes

[teal viper]

Namely, the last Debug.Log that you added.

[rancid tinsel]

i restarted both

and i can see changes in the asset previews

[teal viper]

Well, at these point use the debugger and step through the code.

[rancid tinsel]

also putting a debug before it doesnt work

[languid spire]

just out of interest, in which language is Tree spelt Trie ?

[rancid tinsel]

really weird

[rancid tinsel]

in the UK ig..?

[languid spire]

no it is not

[rancid tinsel]

pretty sure Trie is just another name for a Prefix Tree at least thats what we were taught

[teal viper]

Can you share this script as well?

[rancid tinsel]

https://paste.mod.gg/dwnrlqizjweu/2

there are different tabs on here, first one is the WordLoader

second WordSearchManager

and then the Trie

[teal viper]

You have several LoadWordList methods with mostly the same logs. Make sure you add different logs so that you know which one is being called.

[rancid tinsel]

im only using one at the moment

[swift elbow]

Out of curiosity, Where were you taught that? How do you even pronounce that

[rancid tinsel]

but good idea

[rancid tinsel]

idk like a french person saying tree

or eastern european actually not french

[teal viper]

Both of them could qualify for the call, as int can be converted implicitely to string.

[rancid tinsel]

actually i think its just pronounced Try

and i made it up

[swift elbow]

Make up your mind bro

[teal viper]

That's probably what's going on. And I recommend starting using the debugger, as that would make such issues solvable in a minute.

[rancid tinsel]

added it in, it does use the index one

[teal viper]

What did you add?

[rancid tinsel]

the debug statements

[teal viper]

Ah, well then the issue is solved I guess?

[rancid tinsel]

wdym

[teal viper]

It calls the index one.

And it doesn't have any extra lines at the bottom

[rancid tinsel]

oh my god

🤦

[teal viper]

My advice: learn to use the debugger.

[rancid tinsel]

yes that was the issue 😭

thanks for the help, I actually can't believe that's what it was

[burnt vapor]

Well, as long as you understand that code doesn't magically stop

Either it blocks, blocks in a multithreaded context, threw an exception or never compiled to begin with

Most can be spotted quite easily since something will visibly break

[languid spire]

please don't tell me you just copy/pasted the whole method instead of making the processing a seperate method called by both

[rancid tinsel]

is that not how you use method overloading?

[languid spire]

no

[visual linden]

Well, technically it is, it's just not a very good implementation.
DRY and all that

[hexed terrace]

well, yes, that is an overload.. the signatures are correct.
However, you shouldnt have duplicate code inside the methods

[jaunty bay]

guys my unity just crashed, and stupidly me, i forcely closed it, n i lost 24h+ of progress. anyone knows if theres anyway i can get a recovery from that?

[languid spire]

what is there to force close if the app crashed?

[visual linden]

They lost 24h+ of work, no need to interrogate them on the circumstances when it's irrelevant 😅

[teal viper]

What progress is it exactly? Scene changes?

[languid spire]

It's actually very relevant

[naive pawn]

how do you go 24hr on a single scene without ever saving

[visual linden]

Well, true in a sense. I've a hard time imagining someone not at least saving the scene

[naive pawn]

also how do you get unity to crash and then force close it

[burnt vapor]

24+ hours? Time to download Git

[jaunty bay]

well, more like not responding

[feral moon]

how do I achieve this effect of climbing stairs?

[burnt vapor]

Can we get a "Time to download Git" sticker in this server? Seems more and more relevant each day

[jaunty bay]

but ty anyway! i found 0.bak in temp folder

[languid spire]

so not a crash, a hang, quite different

[naive pawn]

right ok that's not a crash, that's typically called freezing or hanging

[jaunty bay]

yea it went like 20mins so i forced close it

[naive pawn]

[burnt vapor]

As your experience grows you'll learn to save every minute which will prevent these issues

And as you reach this point additional experience will teach you to save twice, three times in a row just in case the first one didn't work well enough

[jaunty bay]

my laptop is so slow tht it takes 5 sec to save my project

so yea, i should still do that tho 😅

[naive pawn]

the bottleneck would probably be with the disk specifically

[visual linden]

I highly recommend Fork, the fast and friendly git client
https://git-fork.com

[tiny wind]

help, my Jump animation wont transition into onwall when im on the right side of a wall

[languid spire]

someone who doesn' save their work for 24+ hours is hardly likely to do both saving and a git commit

[compact stag]

hey guys! i was looking to make a platformer, i was wondering how would i be able to tell in which ground my player would be stepping in? as i want to make a special effect depending on what the player is stepping on

should i make a script and apply to every ground, then use a onCollisionEnter to check if the ground's tag or name is something in specific? or is there a better way?

[visual linden]

You're not wrong, but doesn't hurt putting it out there 😅

[burnt vapor]

$59.99? Outrageous

And pointless. Github Desktop is free and works perfectly

[visual linden]

It's free ;_;

Like WinRAR free

[burnt vapor]

They should definitely clarify that then

This suggests free trial for me at best

[hexed terrace]

fork is available free.. it doesnt force you to pay, though you're supposed to after evaluating

[naive pawn]

i mean isn't that what winrar is

free trial for a period of 1 eternity

[burnt vapor]

Sure

[hexed terrace]

GHD is a v.basic client, the type youd give to artists/ beginners

fork is for devs who need to do more than push/ pull

[naive pawn]

i mean don't ides kinda have good integration already

[burnt vapor]

What exactly is there to Fork that would make Github Desktop the worse option then?

I also think calling it something for beginners is silly. I have been using it since it got released

[hexed terrace]

more advanced options for whatever you need to do with git

dont take offence at that.. it wasnt an insult to you personally

[burnt vapor]

No I get that. It's just that I am looking for actual differences but Google doesn't list that many

If Git-fork isn't paywalled then I obviously take it back. It just seemed to have that or a trial version

Deifnitely looks a lot better than Github Desktop

[hexed terrace]

they're not going to advertise on their site that you can use it indefinitely without paying

Ive used it for... 5 or 6 years without paying.. pops up occasionally to buy it

Learned about it because of vertx mentioning it - and tbh I should prob pay for it, used it for so long

[burnt vapor]

I'm definitely going to give it a look

[night raptor]

Do you really think 6 years is enough to evaluate a software? Give it 10 at least

[visual linden]

Same here, it's also well worth the price.

[languid spire]

Hey, I'm still evaluating Windows 3.1, you know it might take off

[bitter apex]

I'm instantiating a bunch of objects with

Vector3 position = new Vector3((x * gapSize) + 0.5f, (y * gapSize) + 0.5f, 0);
                GameObject tile = Instantiate(prefabTile, position, quaternion.identity);   
                tile.name = $"tile_{x}_{y}";
                tile.transform.parent = TileHolder.transform;```
and it only runs for the first tile, and not any following tiles, because of a nullreference exception

[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;
 }

my Raycaster wont activate when Im on the right side of the wall for my animation script, but does work for my movement script

[teal viper]

Fix the null reference exception then

[naive pawn]

would help if you could specivy where exactly that nullreference exception is

[languid spire]

care to give us a clue?

[naive pawn]

also, shouldn't it be Quaternion.identity

[languid spire]

thats Unity.Mathematics

[naive pawn]

also would help to show the looping part of the code so all the context is included

[bitter apex]

tile.transform.parent = TileHolder.transform;```
is the line with the issue

for (int x = 0; x < objectWidth; x++)
        {
            for (int y = 0; y < objectHeight; y++)
            {
                Vector3 position = new Vector3((x * gapSize) + 0.5f, (y * gapSize) + 0.5f, 0);
                GameObject tile = Instantiate(prefabTile, position, quaternion.identity);   
                tile.name = $"tile_{x}_{y}";
                tile.transform.parent = TileHolder.transform;
            }
        }```

[languid spire]

so, tile holder is null

[bitter apex]

TileHolder is a GameObject i have assigned in the inspector

[languid spire]

bet?

[naive pawn]

wouldn't Instantiate take a UnityEngine.Quaternion anyways?

[runic lance]

there's implicit conversion to Quaternion

[naive pawn]

ah ok

[hexed terrace]

according to the docs it's a capital Q

[night raptor]

That's what I thought, but UnityEngine.Quaterion should be still used if mathematics are not in use

[runic lance]

of course it would be better to use the Quaternion already, but at least there's nothing wrong there 🤷‍♂️

[naive pawn]

there's another one that's a lowercase q

[hexed terrace]

it wouldn't even be compiling if what's there now wasn't ok

[bitter apex]

okay nevermind my bad, thank you. It seemed to work for the first tile I was instantiating but not past that, I just changed it from assigning in the inspector to actually specifying the object in the script, works fine.

problem is sorted, and quaternion.identity works fine for the purpose i want it to

[night raptor]

It works but it should be Quaternion with capital Q

[naive pawn]

are you intentionally using Unity.Mathematics? if not, then you should use the UnityEngine one instead, Quaternion

[swift elbow]

Can anyone share some knowledge on how gameObj.find works and why it's so inefficient? I imagine that it doesn't use a simple for loop because I've never heard of for loops being inefficient but I can't think of what else it could do to achieve this result

[bitter apex]

I was intentionally using the Unity.Mathematics one but I'm not sure if that's a good thing lol. I'll just change it to the UnityEngine one instead then.

[feral moon]

Help please...

I've spent the whole day on this... 😦

[hexed terrace]

not a code question, this a code channel.

Just have colliders on each step, and a player that's smaller than the step so it hits each one

[naive pawn]

it's inefficient compared to other things
probably most notably, the string comparison

[swift elbow]

Can you explain this in a bit more detail? Why is string comparison so bad?

[night raptor]

The method expects UnityEngine.Quaternion so if you used the Mathematics one, it would get automatically converted to UnityEngine.Quaternion but you don't need that conversion if you use the right one to begin with. Afaik Mathematics is mostly used for ECS/DOTS/Burst whatever

[swift crag]

would you like to see an inefficient for loop?

[feral moon]

How to make this?

[swift crag]

for (int i = 0; i < 100000000; ++i) {
  Debug.Log("AAAAAAAAAAA");
}

[wintry quarry]

Linearly searching the entire scene instead of having a fast lookup structure like a dictionary is slow

[swift crag]

I would actually not worry much about the slowness of Find, tbh

[naive pawn]

it's not super bad, it's bad in comparison to other stuff

[wintry quarry]

For loops are slow when they go over a lot of items.

[swift crag]

It has much worse correctness problems

In fact, this is almost always true

GetComponentInChildren is really nasty because it's sensitive to adding and removing components in your hierarchy

[night raptor]

And when you use Find everywhere and your scene grows, you will quickly get to the N^2 territory which might start being a performance issue too

[swift crag]

It is also a bit slow, possibly

But the main problem is that it can wind up finding the completely wrong component

[naive pawn]

rename an object? you're fucked
typo the object name in the hierarchy/inspector? you're fucked
typo the object name in Find? you're fucked
the above, for any object in the hierarchy of the target? you're fucked

[swift crag]

(Clone) (Clone) (Clone) (Clone)

I die a bit when I see someone doing GameObject.Find("Foo (Clone)")

IMO, names should exist solely to make it easier for you, the human being, to identify things

Names (and, more generally, paths) can change

[naive pawn]

to summarize the performance concern; it's not egregious, computers are fast, but it could be so, so much faster with other methods
it searches and does string comparison, both relatively expensive steps for the given task
direct references remove both steps, and they're generally clearer and provide a direct semantic/mental link, so they're generally the much better option

[night raptor]

Yet the animation system relies on it, doesn't it?

[charred spoke]

If I ever see this code pushed to one of our repos Im getting the stick out

[swift crag]

Well, that's kind of unavoidable

[naive pawn]

AnimatorParameter references when 😔

i mean probably not too hard to do actually

[swift crag]

oh, I'm thinking about the paths in animation clips

[tiny wind]

how do I fix this code?

ive been trying for a while, nothings happening

[naive pawn]

oh hm yeah that too i guess

[swift crag]

Names are a very...flexible(?) option

[naive pawn]

though that's not really part of the interface is it

[charred spoke]

I prefer ot use this https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Animator.StringToHash.html

[naive pawn]

how's that different?

[swift crag]

oh yeah -- @swift elbow you were asking about string comparisons a bit earlier, right?

Several places in Unity let you turn a string into some other kind of identifier

[charred spoke]

By several places I think it's animators and shaders

[swift crag]

Animator.StringToHash, for example, or Shader.PropertyToID

[charred spoke]

gotta make that code GC free

[visual linden]

NameToLayer I believe is a thing to

[swift crag]

Unity doesn't tend to use the full names of things internally -- they get turned into some fixed-sized piece of data

[night raptor]

Are string comparisons really that bad in general though (for logic sure, but for performance)? Most strings will differ on the couple few characters anyways

[naive pawn]

yes, in comparison to other stuff

[swift crag]

Part of the problem is that the string has to be shipped off to Native Code Land

[ivory bobcat]

Heap allocation stuff iirc

[night raptor]

That is one problem with strings in general but I don't think comparisons have to allocate anything themself

[burnt vapor]

String comparisons are pretty performant to be honest

[swift crag]

Yeah, I would be less concerned if this was a simple string comparison in C#-land

[burnt vapor]

It also depends on your use case. Maybe you want to compare another way (i.e. hashcode)

[tiny wind]

anyone?

[swift elbow]

But don't for-loops linearly search in the specified bounds? I don't see how it's that different

[swift elbow]

Yeah but how does this relate to my original question? I'm a bit confused on the correlation

[naive pawn]

looping through a scene directly would be linear, indexing a dictionary is not

[compact stag]

hey guys! i was looking to make a platformer, i was wondering how would i be able to tell in which ground my player would be stepping in? as i want to make a special effect depending on what the player is stepping on

should i make a script and apply to every ground, then use a onCollisionEnter to check if the ground's tag or name is something in specific? or is there a better way?

[swift crag]

I was pointing out how you can sometimes avoid looking things up by name. It is a tangent,y es

[hexed terrace]

If your "raycaster won't activate" then onWall() isn't being called when you're in that pos

It also sounds like you've got this code in multiple places ?

[swift crag]

Yes, that's the point

Linear time can be awful

[timber tide]

singleton is the better solution to any find

[swift elbow]

I love singletons 😍 I use 20 at once if I need to

[swift crag]

But, again -- I have much bigger correctness problems with using Find

The performance is a secondary concern

[ivory bobcat]

I read this a long time ago so I'm not sure if it's still relevant
https://discussions.unity.com/t/is-comparetag-better-than-gameobject-tag-performance-wise/33954/5

The key difference between tag and compareTag is that compareTag does not result in a heap allocation. In Unity, retrieving strings from game Objects will create a duplicate of the string, which will need to be garbage collected.

The source I found reports a ~27% increase in performance of compareTag(aString) vs. using gameObject.tag == “aString”;

Source:
Unity 5 Game Optimization by Chris Dickinson

[swift elbow]

I was always told that it's too expensive so that's what I rolled with

[swift crag]

that's the easy explanation, I suppose

[naive pawn]

it's relatively expensive, i guess, but that's generally not the cinch

it's generally better to avoid strings if you can, they're kinda fragile

unless you're doing something where strings can be typed like an enum, like in ts

[swift crag]

Yeah, it's still relevant

[ivory bobcat]

Might be out of context as well. I was assuming they're attempting to access the tag property for comparison - I wasn't here for the whole discussion.

[naive pawn]

(the original question was about Find)

[swift crag]

But that's more of an issue with how most Unity properties result in a call into native code, which has to allocate memory to give you the result

[timber tide]

using literals is usually the best way about it but lot of features with unity still require that string comparison unfortunately

[naive pawn]

using literals? strings can also be literals wdym

[timber tide]

whoops I mean variables

[swift crag]

perhaps you mean using things like Animator.StringToHash

[timber tide]

godot people were saying that a lot of the string comparison is relatively fast

a lot of its features do use a lot of string comparisons

I generally just like the more type-safe nature and having the compiler know beforehand

[night raptor]

What the biggest issue is, is up to debate. The bottom line is that the Find methods are bad and there's always better ways to achieve what you were trying to achieve with it

[tiny wind]

yeah, but idk why it isnt being called

also I have that code on my animation and movement script file

[wintry quarry]

There are faster ways to look things up than a linear search. A dictionary/hashtable allows for O(1) lookups

[night raptor]

Often Find is even used for things that could be directly referenced otherwise (even drag and drop to a field in editor, singleton or something else)

[timber tide]

or instead of finding that object, let the object itself do some callback/subscribe when it is created

[night raptor]

Things like FindObjectsOfTypeAll in editor scripts I would say is totally acceptable but if the game logic relies on Finds, it is indicative of bad design choises

[grand snow]

If i load a scene that has a main manager class ill use FindObjectOfType() to get it initially but that's about it.
An alternative is to search the scene root objects for the component.

[night raptor]

Wouldn't even simple singleton do the same?

[visual linden]

If performance isn't an issue, such as in Awake etc, I think it's perfectly acceptable using FindObjectByType. We've all got games to make, after all.

[grand snow]

It could but we wouldnt access or use it via this singleton static ref anyway

For the games that do this its only 1 call when the scene is loaded in additively and thats it

[burnt vapor]

Why cant you just use a static reference if there's a single manager? I don't see the issue

There's very little reason to use Findtype methods, if at all

[grand snow]

When potentially many people can work on a game its better to avoid stuff that can be miss used down the road

[languid spire]

it might be more advisable not to work with people who are likely to miss use anything

[night raptor]

In this case I wouldn't really worry

[visual linden]

This is so true.

[grand snow]

its not my choice who works on a project i just work on what im told by the PM

[burnt vapor]

Miss stuff? Seems pretty clear that a single instance manager might have a singleton pattern applied to it. Using a Find method sounds like a solution for people that didn't even bother looking for the correct approach

[night raptor]

heck, I'm even miss using my own code

[visual linden]

Always assume someone is going to see your code, try to understand it, and build upon it, and then design it in a way that makes your intent abundantly clear and doesn't invite to misuse.

[grand snow]

😆 ha this chat

[burnt vapor]

If I want to use a manager, the first thing I'd probably do is check if there's an Instance property on it

Which is pretty common in .NET for default single instances btw

[grand snow]

ill end with this: i dont want the static field to exist so its not miss used when a pre existing system/design exists for other components to access said manager 🙏

[languid spire]

That is generally a sign that you are not actually designing anything, just making it up as you go along

[night raptor]

Fully agree 😂

[burnt vapor]

I have no idea what issue you're referring to here

[grand snow]

no need to worry

[burnt vapor]

Sounds easier to me that you can access a singleton instance through a static property instead of having a badly coupled system using smelly Find methods

[runic lance]

if you're using DI extensively there's no need for singletons basically

neither Find methods

[burnt vapor]

Also that, a proper DI system should essentially replace everything in the end, and it will be easier to replace a singleton than a Find method

I cant find any info on this, and I'm trying to make AI for my zombies. I want them to walk around obstacles using ray casting - how could i get something like the result in the video?
I do not wanna use the Unity AI system, because it seems like overkill, for just simple zombies in my case.

[burnt vapor]

Best case scenario there's a single provider providing registered instances based on the context. Either through a factory or as-is

[timber tide]

Singletons aren't truely static though which is why it's more preferable to use them if you're worried about misusing globals

[grand snow]

to be clear, 1 single find is used and all the rest is manually passed dependencies + inits without any finds.

its purely to "connect" the newly loaded scene to the loading service

[burnt vapor]

That's definitely a lot better than what I thought you had, yeah

[grand snow]

blah blah other stuff

I have refactored code by others in such games to remove Finds as i accept they are not reliable or good to use.

[echo copper]

i got it!

my mistake was in other thing

[timber tide]

Keeping the game manager as the only singleton and doing service locator pattern is also another great idea if you don't want to bloat up a project static types

[visual linden]

Reason you don’t make your classes accessible by default is so that junior programmers will come to you asking how they can access it, and you tell them “You don’t. What exactly is it you’re wanting to do?”

[burnt vapor]

So they resort to just using a Find method to access a random instance which might not even be a singleton?

[visual linden]

Heh, well ideally not. But that's part of this whole discussion right, of knowing when FindObjectOfType should be used and when it shouldn't.

If you're using it to access a class that you didn't write- you probably shouldn't be accessing it.

[echo copper]

Guys, how can I change object's position according to its parent's position?

[visual linden]

Whereas if it is a singleton or has a static reference, it invites you to access it

[timber tide]

transform has a localposition, but in general anything specified as local means it's relative to the parent

[echo copper]

Okay, i will try it

[wintry quarry]

There are faster ways to look things up than a linear search. A dictionary/hashtable allows for O(1) lookups

Binary search trees allow for O(logn) lookups

[swift elbow]

im kinda familiar with what O notation is and how it works but im having trouble visualizing how much of a difference this is. can you give a factor by how much slower O(logn) is to O(1)?

[naive pawn]

O(1) is 1 operation
O(logn) divides n until you're left with 1; however many times you divide is how many operations, what you divide by depends on the data type (but usually log_2 in the context of computing)
O(n) is n operations

[swift elbow]

that doesnt sound so bad...

[naive pawn]

this isn't how it plays out exactly, since big-O describes how fast it scales, so it leaves out constants and lesser-degree terms
iterating over a list once or twice are both O(n)

an example might make more sense actually

[burnt vapor]

In general it's not but you should try to get as cose to O(1) as possible

Especially when code performs often these things matter

[wintry quarry]

If the list is 1,000,000 elements long then:
O(n) is 1,000,000 operations
O(logn) is like 20 operations
O(1) is 1 operation

So with a list that long, O(1) is 1,000,000 times faster theoretically

it all depends on the list length

in practice you probably have 100 or 200 GameObjects in the scene

[timber tide]

I've like 100k trees in one of my scenes

[naive pawn]

suppose 2 lists, one with 8 elements, another with 64 elements
an O(1) algorithm will take the same time for both (getting the length)
an O(logn) algorithm will take twice as long to do 64 than 8 (n-element binary tree)
an O(n) algorithm will take 8 times as long to do 64 than 8 (n-element list)
an O(n^2) algorithm will take 64 times as long (nxn grid/combinations)
an O(2^n) algorithm will take 72057594037927936 times as long (0-1 knapsack)
an O(n!) algorithm will take 3146997326038793752565312235495076408801228079725823219216316824782110720000000000000 times as long (permutation)

[swift elbow]

brother where did that factorial come from

or is this just an example for example's sake?

[naive pawn]

it's an example

[runic lance]

you can do a factorial it if you set your mind to it

[naive pawn]

O(n!) algorithms do exist, like permutations

i can't think of anything that isn't just a permutation in more words

[wintry quarry]

Some naively written algorithms have factorial running time

[naive pawn]

oh yeah, there's an algorithm to find the determinant of a matrix that's in factorial time

[swift elbow]

you must have been looking at mine...

[silk meteor]

so im trying to make a pong copy, just to test my knowledge, and ive encountered one issue, im not changing the y axis, they are set through the rigid body, to give a more natural feeling, however, once it hits the ground, the y velocity is set to 0, is it possible to just invert it? so +8 becomes -8, and vice versa

[naive pawn]

uhh i don't think pong should have a "ground"

[silk meteor]

watch a pong video

[swift elbow]

thats entirely possible, yeah. depends on your setup

[wintry quarry]

im not changing the y axis
Of what?

however, once it hits the ground, the y velocity is set to 0
Once what hits the ground?

[naive pawn]

maybe set your physics materials to 1 bounce

[swift elbow]

i think they mean the walls

[silk meteor]

1. the ball

2. the ball

[silk meteor]

no, the walls don't have collision, once the player touches the wall, the game is over

the floor is a floor

and so is the ceiling

[swift elbow]

im confused now

[naive pawn]

there's like, 5 different y axes for a gameobject with a rigidbody

[wintry quarry]

In OnCollisionEnter use collision.relativeVelocity and Vector2.Reflect to calculate the new velocity

[naive pawn]

ok this is starting to not sound like pong

[silk meteor]

have you never seen pong

[naive pawn]

yes

[silk meteor]

you bounce off the floor and ceiling

[naive pawn]

no, the ball does that

[silk meteor]

ok im just gonna crash out

[naive pawn]

you control a paddle, not the ball

[silk meteor]

i never said you control the ball

[naive pawn]

the ball is supposed to touch the walls

that's like, how it bounces

[wintry quarry]

ok this is clearly just a case of you guys using different terminology for walls and floors

[swift elbow]

wait are we talking about table tennis or virtual pong?

like against an AI

[silk meteor]

when did we start talking about table tennis wtf

[naive pawn]

you said, once the player touches the wall, the game is over? so the player is the ball?

[swift elbow]

idk chris mentioned paddles

[naive pawn]

pong has paddles

[silk meteor]

oh my god its called common sense

[swift elbow]

table tennis has paddles

[silk meteor]

obviously when im talking about pong and something moving on the x and y axis, its referring to the ball

maybe i misspoke but its still common sense

[naive pawn]

ok no the problem is people come here way too often talking about stuff with the wrong words so im not automatically assuming you're referring to that lol

saying the ball is the player makes it really confusing what you're actually talking about

[silk meteor]

well now we know

[naive pawn]

are you saying the walls as in, the right/left edges of the screen, and floor/ceiling as the top/bottom edges of the screen

[silk meteor]

yes

in fairness it is a top down game not platformer

so thats mb

[naive pawn]

yeah so if you're doing physics i think you could just make everything bouncy without any friction or drag

[wintry quarry]

My recommendation: #💻┃code-beginner message

the physics engine is not designed to give perfect elastic collisions etc, and won't.

[obsidian plaza]

so this is my game im working on and i have a question on how i could improve the note hitting feedback in regards to the animations on the monster.

whenever i successfully attack, miss an attack, or dodge an attack, an animation is played corresponding to that on the monster. the issue is that it seems a bit jittery and doesnt always do the right animation when the gameplay starts to get faster.

ideally, attacking the enemy will cause it to scale down and being attacked will cause it to scale up but will always scale from its current scale so it doesnt look jittery. another thing is that once it is finished scaling, it needs to slowly return back to the original/normals scale. does this make sense and is there an easy way to do this?

[cerulean badger]

how do I make a 2d object clickable? I've searched in yt and most of the tutorials are for 3d and the 2d ones are just some mumbo jumbo or free assets that dont actually explain anything

[wintry quarry]

Basically the same as 3D just with 2D colliders instead of 3D colliders and PhysicsRaycaster2D instead of 3d

[gaunt sandal]

what kind of 2d object is it?

[obsidian plaza]

what i do personally is have a child with an image and turn down the opacity since an image has a raycast on it already

but maybe not the best way

[wintry quarry]

You need:

• Event System in the scene
• Physics Raycaster2D on your camera
• Collider2D on the object
• Script that implements IPointerDownHandler on the object (alternatively you could use the EventTrigger component, but I don't recommend that)

This is the best way

[cerulean badger]

i want something like a button but its part of the map instead of an ui button

[gaunt sandal]

by part of the map, do you mean like a minimap, a physical map in game, or something else?

[cerulean badger]

i mean part of the place where you walk in

[hexed terrace]

the environment

[cerulean badger]

yea

[hexed terrace]

Praetor has given you the answer

[gaunt sandal]

the one praetor is definitely an option, but i'm checking if there's a simpler method

[wintry quarry]

There are simpler ways, but the one I shared is the best because it will automatically give you appropriate interaction with UI elements and other objects that cover it

[cerulean badger]

ok then, ty

[wintry quarry]

As well as giving you the option to easily implement other interactions like OnPointerEnter, OnPointerExit, OnPointerUp, etc.

[languid spire]

IPointerClick handler

[grand snow]

• add a physics raycaster to the camera and an event system to the scene

[wintry quarry]

Yes those were mentioned #💻┃code-beginner message

[grand snow]

I just read the small reply bit 😂
We need more threads

[wintry quarry]

imo every question should be a thread

I guess that would be the forum style discord channel though.

[obsidian plaza]

another way to ask this is:

is there a way to increase scale to 2 over the course of 1 second no matter what the original scale was? and then after it reaches 2, bring it back to 1. I know this is possible with lerping in a script but setting up all the different interactions would be annoying so im hoping theres a more automatic way

[languid spire]

what different interactions? This is literally 1 coroutine for all cases

[gaunt sandal]

possibly silly question, but is it possible to just make this a ui canvas gameobject in the world instead of the screen space? then just utilize the button gameobject as that ui canvas' child?

[wintry quarry]

float targetScale = 2;
float animationDuration = 1;

float scaleDifference = targetScale - currentScale;
float speed = scaleDifference / animationDuration;

Then use Mathf.MoveTowards each frame with:

float currentScale = Mathf.MoveTowards(currentScale, targetScale, speed * Time.deltaTime);```

[wintry quarry]

There are no UI elements involved in what I'm talking about.

Is it possible to make world space UI elements? Yeah of course but it's not necessary here

and it means a whole separate set of objects.

[gaunt sandal]

ah right he asked for making any 2d object clickable

[smoky jungle]

I hope someone can help because I have absolutly no clue how to work on this problem.

[obsidian plaza]

i guess i can do something like this or the coroutine as steve said, thanks. Will just need to make sure to wait a second and bring the scale back to the original after each hit

i was gonna possible change the position as well as scale but its probably not needed anyway

could use the same logic

[queen adder]

Hello

[gaunt sandal]

hello

[languid spire]

I think you are asking in the wrong channel, remove from here and try #🔀┃art-asset-workflow

[smoky jungle]

Aight, thank you!

[placid ferry]

I got told to post this here, but can someone help me with this issue

[languid spire]

you were also told how to post code which you have conviently ignored

[hexed terrace]

you were also shown how to share code, that wasn't one of the ways

[placid ferry]

Dude Idk how to do this, Im illiterate

[languid spire]

tough

[hexed terrace]

That's ChatGPT code innit

[placid ferry]

Idk, I learned it from yt?

[hexed terrace]

surely you know whether you copied it from ChatGPT - all those comments scream "generated by AI"

[languid spire]

you mean copy/pasted, not learned

[placid ferry]

Learned tyvm

[languid spire]

ok so what does it do?

[visual linden]

What is the point of this arguing

[placid ferry]

It allows you to lean?

[placid ferry]

It all started because I didn't know what to do?

[echo copper]

how to make children object not to follow parent object?

[hexed terrace]

either move it in the opposite direction of the parents movement, or unparent it

[wintry quarry]

Don't make them parent/children if you want that.

[visual linden]

I agree with Steve's general sentiment, but I think we can probably try to help you First before going into why ChatGPT & Co are usually a waste of time 😅
Maybe you can describe what it is you're trying to accomplish?

Is it Mouse Look?

[placid ferry]

So with that code it allows me to lean left to right kinda like Rainbow 6, But I tried everything connected to that and it still does the jitter, but yes its something with the mouse look

[burnt vapor]

I don't see the point in helping somebody that didn't bother to make their own code. I suggest you take lessons in Unity to get familiar with how to write code yourself, and then come back with actual code so that we can help you solve any possible issues

[placid ferry]

its nothing with the code

[burnt vapor]

If it's not the code, then what is?

[placid ferry]

What do you think im trying to figure out

Like hello?

[burnt vapor]

Is it obvious why getting your code from AI gives you very little knowledge on what it actually does? And now you end up with a bug that you are unable to solve yourself

[placid ferry]

its not from ai, thats what im tryna say?

I don't even have an account for ChatGPT

[burnt vapor]

It's very clearly from AI

//(You don't have to use the mouse buttons if you don't want to, you can do "Input.GetKey(KeyCode.Q)" for example)
Who are you talking to here?

[crimson pike]

Is using fixedupdate for movement updates similar to multiplying motion by time.delta in regular update calls?

[naive pawn]

not really no

they both have their own deltaTime

[visual linden]

Maybe we can pretend @placid ferry came on here just asking a very broad question, how to.. "implement leaning like in Rainbow 6"?
And we workshop it from there?

[crimson pike]

But both methods would make consistent movement independent of frame rate?

[naive pawn]

fixedupdate and update don't run on second intervals, if you need to convert per-time stuff to be used per frame/physics tick, the deltaTime converts from the per-second value to the per-frame/tick value

[rich adder]

do be fair those don't look AI comments.
Typically you use
//Gets Input For X Input.GetKey

[visual linden]

I think they mentioned it was from a youtube tutorial. Linking to it might be a good start too.

[rich adder]

there is too much thought in the comments to be AI

[naive pawn]

you could, but there's more to it than just update vs fixedupdate

[burnt vapor]

Generally that's exactly what AI does

[crimson pike]

Well I’m not using physics too much in this game

[naive pawn]

update is a change per frame
fixedupdate is a change per physics tick

[naive pawn]

then there's not much use for fixedupdate

just use deltaTime

[crimson pike]

Icic thanks

[placid ferry]

It was yes and thats why there is comments In the video he coded the WHOLE thing right infront of me, but do you want me to link it or? mb I misunderstood

[rich adder]

AI comments are more like stating the obvious like
// Jumps the Character void Jump
also inconsistent capitalizing, AI Is more predictable

The best way to write comments for yourself is to write comments as if you had an audience

Because the you in a week is a different person from the you now

[visual linden]

So if I understand it correctly,
in the video, you're trying to lean by pressing the lean key, but after it finishes leaning, it snaps back to center?

[placid ferry]

Yes

[placid ferry]

and do I just link the code thing or is it a download

[rich adder]

paste the code on the website , save and send link. Its difficult to view code how you sent it on mobile

[visual linden]

Sounds like your animator might have a transition back to your idle state that doesn't have its transition rule properly configured (so any time the lean animation finishes it automatically goes back to idle, when it should be waiting for you to release the lean key).

[placid ferry]

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

[placid ferry]

the think is it does it either way.

when leaning and on idle

if ur free I can call and show you

wait no you were right

Im super sorry abt that

[visual linden]

Fantastic :D So you think you're able to figure it out?

[placid ferry]

I'll try anything and if I can't do you mind if I DM you if I can't figure it out?

[visual linden]

I'd rather you didn't 😅 But if it's animator setup stuff, we have #🏃┃animation and the people lurking there are probably a lot better at that stuff than I am.

[placid ferry]

Thank you sm

[naive pawn]

this server exists, utilize it

[placid ferry]

ok, mb

[visual linden]

To be fair, after the response they got initially I can see why they'd shy away 😅

Based on the error I'd guess you need to disable the Animator before trying to change the animator controller.

hi i've got these 2 lines

        unspawnedMatch.transform.SetParent(null);```
but neither do anything? unspawnedmatch has a rigid body, a parent, and a reference, the code is running, i've debugged all this already. but iskinematic is true, and the parent is not null after running this. how come?

[naive pawn]

how exactly did you debug them?

[obsidian plaza]

make sure that unspawnedMatch gameobject is the correct object?

[naive pawn]

are you looking at the right object?

[lucid quiver]

can u show the full script instead of just this snippet?

[wintry quarry]

make sure the code is actually running
make sure there are no errors (at runtime)
make sure there isn't other code undoing it

[inland latch]

yes, every match that spawns is kept as a parent, there is no other objects it could be with the name that's being debugged

it's false

in code and in editor

show us

ok then

it's working fine

so what's your question?

[inland latch]

wait not in editor

[wintry quarry]

99% chance you're simply looking at the wrong object

Which object are you looking at?

The prefab?

[lucid quiver]

is match grab getting detected?

like is OnMatchGrabbed getting called ?

have u checked?

[inland latch]

well yes cus all the debug logs are running

there is 0 other objects with the same name in the hiearchy

[wintry quarry]

time to start showing some screenshots

show - e.g. - the full unity editor with the object selected and the inspector with rigidbody showing kinematic true and the log in the console saying it is false

[inland latch]

what u wanna se?

[wintry quarry]

I think I made it very clear what I want to see

[inland latch]

this is literally gonna show what i told u mate

[wintry quarry]

Show it

[polar acorn]

One screenshot, full unity window. Object selected, console visible

[inland latch]

literally why, is this a "i dont trust you" thing?

[polar acorn]

Yes

[inland latch]

i don't think it's that unreasonable to not wanna show my entire project mate

[wintry quarry]

This isn't what I wnted to see

I wante4d to see the full unity editor window

[inland latch]

if you don't know how to help then don't act like you can no need to act like im just lying

[swift crag]

Then we will not be able to assist you.

[wintry quarry]

Because 99% of the time, things are not as people say they are, and simply showing the screenshot reveals that

[inland latch]

i have showed you what you asked to see

[wintry quarry]

WE're not accusing you of lying

just being mistaken

[wintry quarry]

No, we have no idea which object that is the inspector for

[polar acorn]

Also, combine the logs into one:

Debug.Log($"{unspawnedMatch.name}'s rigidbody is {unspawnedMatch.GetComponent<Rigidbody>()?.isKinematic}", unspawnedMatch);

[wintry quarry]

the whole point is I think you are looking at the inspector for the wrong object

[polar acorn]

It is

[naive pawn]

also, add the gameobject to the log so you can actually check the object directly

[polar acorn]

You have not

[inland latch]

not really? people making private games is very common

[naive pawn]

Debug.Log($"{unspawnedMatch.name}'s rigidbody is {unspawnedMatch.GetComponent<Rigidbody>()?.isKinematic}", unspawnedMatch);
