InventoryManager knows nothing about the two, UI slot only knows about UISlotsManager and registers itself with an event UISlotsManager listens to (mouseclicks, onDrop, the usual stuff)

UISlotsManager also gets info from events on InventoryManager

[wooden socket]

well im back

I followed what you guys said earlier and did some more looking into C#, and im slightly confused on a specific aspect

I want to pass a function from one script to another, and I even looked at my other UI script and im still a small bit stuck

in my screenShake code, its all the logic needed for the screen to shake, I just want to call the shake screen function when the bird object collides with this object

is there anything im doing wrong here?

[tawny thicket]

how do i switch a model

[dense plume]

Looks fine on this end, what is the shake camera function on the other side?

[wooden socket]

hey look, im getting better!

okay lemme send that

[dense plume]

More context please

[polar acorn]

[wooden socket]

i did

idk why u think I didnt try that lol

switch a model in what way ? also where is the coding question part

[wooden socket]

https://gdl.space/ronofokovu.cpp

here ya go

[polar acorn]

Because if you had tried it, you would know if it worked or not, and not have to ask if it worked or not

[wooden socket]

i did try it

i said that

is there anything im doing wrong

[tawny thicket]

i thought it would have something to do with coding

[dense plume]

Just show the camera shake method

[wooden socket]

ob mb lol

[wintry quarry]

Is there anything that leads you to believe you are? Is it working?

[wooden socket]

I LOVE UR PFP

[rich adder]

switching out a model can be done in code too sure. It all depends what you're doing

[dense plume]

It sure could, what are you trying to do

[polar acorn]

Is it working

if not, then probably

if yes, then no

[wooden socket]

when i tried it, the screen didnt shake

[rich adder]

we need a flow chart for this channel , of "have you tried debugging it first"

[quartz nimbus]

why isnt unity accessing my UI I have the using UnityEnging.UI; on but its not accessing my object resolutionDropdown

[wooden socket]

to be fair, I could make a new script for the shake

[polar acorn]

Okay, there we go, a statement of problem.

Log the tag of the object you're hitting in OnTriggerEnter2D before the if statement. See if you're ever actually colliding with something tagged "bird"

[wooden socket]

wait it would be easier if its jusyt one mb

[rich adder]

you didnt create it

[quartz nimbus]

wdym didnt create it

[polar acorn]

What is resolutionDropdown?

[rich adder]

what is reslutionDropdwon ?

[stuck palm]

@swift crag i dont think im doing this hash thing correctly. I'm getting replays that work, but the hashes are apparently mismatched.
https://gdl.space/iyidasejad.cs

[rocky canyon]

you dont have anything in ur script that defines what resolutionDropdown is

[hexed terrace]

You haven't declared anything called resolutionDropdown

[tawny thicket]

i'm trying to change the model of something to make it into this and i have no idea how, it's for a joke

[rocky canyon]

Quadrakill QuintupleKill!

[hexed terrace]

if you hover over the red error, it will tell you it doesn't exist

gotta learn how to use VS and read the info it gives you

[polar acorn]

Export it as an FBX, import it into your project, and change the .mesh field of a meshrenderer to this one

[swift crag]

I'd suggest adding a way to find exactly what differs

so, walk through both game states and log anything that mismatches

[quartz nimbus]

ohhh ok im following a brackeys tutorial and they got had no problems but i guess there was an update along the way ok thx for the help

[rich adder]

I dont have blender on my phone but you can use FBX then swap it out there

[polar acorn]

I can guarantee they didn't use a variable they never declared

[stuck palm]

isnt that what the hash thing is for, though?

[swift crag]

The hash makes it easy to check if two states are identical

You want to find out what isn't matching

[rich adder]

even if its brackys 🙄
dont think they would just have that undefined var there

you missed a step

[dense plume]

Declare this resolutionDropdown at the top as a Dropdown type object

[quartz nimbus]

ye I mightve be sleep deprived i missed that they made a variable already sorry

[tawny thicket]

ok, approximately how long would this take for me to do?

[rich adder]

follow the tutorial but better

[stuck palm]

im overlaying recorded videos of the original video and the replay and theyre literally frame perfect, could it possibly be that my hash implementation is wrong and im adding things in the wrong order?

[polar acorn]

probably like, a minute

[tawny thicket]

oh ok

cool

[swift crag]

that's why you need to compare individual parts of the game state

[polar acorn]

like, you could have just done that in the time it took to ask that question

[rich adder]

trial and error a dying breed or what..

[wooden socket]

added the debug log. its adding score but not shaking screen

[swift crag]

A hash is convenient to send over the network. But if you have two GameStates, why not compare them element by element?

[stuck palm]

i'll probably just do that, then. I'm not sure what else a hash takes into account when youre creating it but i feel like im writing the code wrong if the game is fine but the hash is telling me its wrong, or maybe its a floating point math thing

[polar acorn]

Can you show the inspectors of your CinemachineBasicMultiChannelPerlin component, and the screenShake?

[dense plume]

Ok so this is some issue with the shaker code. Is it actually retreiving the cinemachine component? Add some logging over there and make sure each step of that function is behaving as intended

[wooden socket]

i can definitely do that

heres my virtual camera object

I assume I should put the script on the object that actually is being collided with right?

[polar acorn]

Well, there appears to be a warning on your Noise profile, expand it

see what it has to say

[wooden socket]

oh shoot

[polar acorn]

Doesn't matter, as long as it's properly referenced. If it wasn't you'd be getting a null reference exception

[wooden socket]

well now the object shakes! but not when its being colldies with

just on its own

[polar acorn]

you probably need to start the AmplitudeGain at 0

[wooden socket]

okay i changed it

[polar acorn]

There should be a field in the inspector for it

[wooden socket]

lets see

okay so I made it 0, and when the objecy is collided with I get this error

[polar acorn]

All right, what's pipeCollide line 20?

[wintry quarry]

Doesn't seem like you assigned ShakeCamera

assuming it's the lightbulb line

[wooden socket]

i do that in the inspector right?

[wintry quarry]

yes

[wintry quarry]

However if I understand properly, this script is on the pipe

which is a prefab

so you can't

You would have to assign the reference at runtime (when spawning the pipe)
Or use the singleton pattern again like you did for the ScoreManager

[wooden socket]

well, it did work

the pipes shake lol

[wintry quarry]

then presumably your pipe is not a prefab

it's in the scene

[wooden socket]

mhm

now, im going to try and add sfx to when it collides. Im going to try and do it all on my own, and if there is a problem I will report back

thank you for the help so far. ur making a mans dream come true <3

[polar acorn]

See how much smoother this goes after a full night's sleep

[wooden socket]

true!

lol

[wooden socket]

okay im back BUT it should be easy and not a code thing

I added code so it plays a sound when it collides with the pipe, but it isnt playing the noise

the audio listener on the camera is on, the clip is even inside of the inspector slot

nvm it works, i had to add something small

lol

[queen adder]

Does anyone know what the issue may be here? Im trying to make it so if Box Collider Collides with another there should be a message in console 🤔

but for some reason cant get it working

The steps are clear ☝️

[swift crag]

Follow all of the steps. Do not skip any of the steps.

[queen adder]

If I have to use visual studio community instead of enterprise (what I have been using) will it still be the same? / will I run into errors with my code? 🤔

[polar acorn]

If you have enterprise, just use that

[queen adder]

it wouldnt let me modify to add the unity stuff 🤔

uhh nvm I think I got it

[stuck palm]

@swift crag after serialising both the recorded state and current state, i can see some non-negligible discrepancies. could that possibly be because of script order execution or?

[swift crag]

That is very possible. You need to ensure that everything happens in a very explicit order

[stuck palm]

everything related to characters and projectiles i hope you mean lol

[swift crag]

You could do this by setting script execution orders for everything, or you could explicitly run update methods on everything

[stuck palm]

cus i've got like 200 scripts 😭

[swift crag]

and, in fact -- if you want to be able to do rollback eventually, you'll want to do the latter

Although, actually, if everything is using FixedUpdate, you'd be calling Physics.Simulate() manually anyway

so FixedUpdate would be getting called

[stuck palm]

honestly for now, i'll just do script execution order stuff

[stuck palm]

does it matter if I dont set the order for things like UI and other things that arent integral for the game simuation?

[swift crag]

That stuff doesn't matter, no

although, you do probably want to update the UI after the game state is updated!

otherwise it'll be a FixedUpdate behind

[stuck palm]

that is true

okay, thanks for the insight

[swift crag]

(But you probably want to update the UI in Update anyway)

[swift crag]

You need to separate your game state from the presentation of the game state, basically

[stuck palm]

i'll do character simulation first, then projectile simulation, then whatever else i need to check what is important here

i guess i'd need to update the kinematic character controller after the character

because the character decides the velocity basically

[queen adder]

this aint working, Any Ideas? also the "Unity API Reference" doesn't show up under help 🤔

[swift crag]

Show your External Tools settings, as well as the Package Manager window.

[queen adder]

where I find those at

[swift crag]

I thought you followed the instructions you were linked to.

[queen adder]

yuh

[polar acorn]

So what did you open for the step that had you change the external tools settings

[swift crag]

The instructions very clearly instruct you to go to both of these places

[summer stump]

Then you would know where it is

[queen adder]

I see one sec

[swift crag]

I don't know how much more clearly I can state this #💻┃code-beginner message

[swift crag]

Okay, both look fine.

Close Visual Studio, click "Regenerate project files" in the External Tools window, and then double-click a script asset to re-open Visual Studio

[languid spire]

best to delete the .sln and .csproj files in the project

[swift crag]

yes -- those are the files that Unity generates

they shouldn't need to be deleted, but, you know,

I've seen it be a problem before.

[languid spire]

well the .sln is not always regenerated when switching from VS Code to VS

or vice versa

[rocky canyon]

i rename and move projects around a lot.. i always delete my .csproj inbetween

[oak tapir]

i need some help i put a code in unity or whatever and i tested it and i can walk but when i do when i stop pressing the w key to go forward it keeps going forward for like 1 second

[queen adder]

alright did that, I don't know if "Regenerate project files" worked or not as when I press the button nothing happens

but im back in visual studio and I dont think we working still

[polar acorn]

Now reopen visual studio, do you have errors underlined in red now

[queen adder]

umm, I dont think so??? 😭

[swift crag]

Do this, then regenerate the project files again #💻┃code-beginner message

If the issue persists after that, screenshot your entire Visual Studio window.

[queen adder]

alright

[swift crag]

That isn't your entire window.

When you don't know what you're looking for, you should err on the side of providing too much information

[queen adder]

my bad I was screenshotting the code because digiholic asked if my errors where underlined 😭 🙏

[swift crag]

ah, I see

[queen adder]

so delete the .sln here?

[languid spire]

yep and the .csproj

[swift crag]

Yes, along withg the "Assembly-CSharp" project file.

[queen adder]

[polar acorn]

Ignore

[languid spire]

Ignore

[polar acorn]

You already know there's compile errors

[queen adder]

aight this is my visual studio now 🤔

[languid spire]

Still not configured

[short hazel]

Select View > Solution Explorer and take a screenshot again

[swift crag]

you're looking for the "Miscellaneous Files" indicator here: that means Visual Studio doesn't think this file is part of a project

and yes, that's the next place to look

[short hazel]

Right-click the Assembly-CSharp project and select Reload With Dependencies

[queen adder]

Oh shit

wait I think we are working

theres color

[polar acorn]

Yes, there you go

At least... somewhat? The error still isn't underlined

But it's highlighting Unity stuff at least

[queen adder]

Uh I think we workin now

[polar acorn]

Ah there we go

Now, onto the second point:
You got a function in your function

[queen adder]

not gonna lie idk what this means 🔥 🗣️ 💯

[polar acorn]

It means you have put a function inside another function

[summer stump]

OnTriggerEnter COULD be in Update if you remove the word private. But Unity will not call it from there

So remove it from Update

[polar acorn]

unless you are absolutely certain you should be doing that, it's usually a mistake

[queen adder]

im just following a youtube video 😭 🙏

[summer stump]

This is not what they did

I guarantee you that

[polar acorn]

Then you should follow the video, because they certainly didn't put a function in a function

[queen adder]

uhh this is what they did

and it seems to work

I guess

[summer stump]

Zoom out, that is not the issue

[polar acorn]

Show their full script

[swift crag]

Can you quit spamming the emojis before I have an aneurysm

[summer stump]

The issue is that you put it INSIDE of Update

[queen adder]

[summer stump]

See how it is very different

[swift crag]

notice how this is not inside of an Update method

[summer stump]

Stop

[swift crag]

I can't wait for summer break to be over.

2022-07-19 to 2024-06-27

[queen adder]

Mine -

His -

[polar acorn]

Yes. Because you put it in a function

[queen adder]

am I just stupid??? 😭

[summer stump]

Again, you are looking at the wrong part

[polar acorn]

And they did not

[summer stump]

It is INSIDE OF UPDATE

[queen adder]

OH

I SEE

😭

[summer stump]

Fucking stop with the emojis

[queen adder]

my bad my bad

[polar acorn]

[summer stump]

I meant to ask, did you make a server to get your own emojis and use them everywhere?

[polar acorn]

I have a server for my randomizers, streams, and minecraft server

[summer stump]

Nice

[polar acorn]

but I have added emotes solely to use in this server

[summer stump]

I knew it

[queen adder]

Never been so happy to see some gray text

[oak tapir]

how do i make the green thing aline with the plane? cause when i press play and i walk on it i cant walk on the plane i just walk on the green thing

[swift crag]

Show me how the "Scene" object is scaled.

[oak tapir]

wdym like the whole thing?

[rocky canyon]

dont scale ur root objects

[swift crag]

No. I want to see the scale of the "Scene" object.

It's the object named Scene.

Show me its inspector.

[rocky canyon]

its probably whacky.. you heard it first here 📺

[oak tapir]

k hold up lemme screen shot

[rocky canyon]

booya

[swift crag]

There's the problem.

[oak tapir]

what i do?

[swift crag]

You have a non-uniform scale on a parent object.

When you do this, it causes skewing of child objects that are rotated.

[rocky canyon]

dont scale ur root objects...

scale children objects..

[swift crag]

As the child rotates, it lines up with the X/Y/Z axes of its parent differently

causing it to distort as it rotates

[rocky canyon]

[swift crag]

The Box Collider component cannot deal with this properly.

[rocky canyon]

if ur parent is 1:1:1 rotations and sizes will be fine for the children

[swift crag]

it winds up separating from the visible cube (which does skew "properly")

[rocky canyon]

if u scale the parent to something weird the children grow up to be something weird

[oak tapir]

so hoe do i fix?

how

[swift crag]

don't do that

make its scale uniform

e.g. [3,3,3]

[rocky canyon]

don't scale the root object ... if u need that collider thats on it to be scaled weird

[earnest shore]

I'm trying to use courtines to make the player only able to jump once every 10 seconds. Anyone know why this isn't working ?

    {
        StartCoroutine(JumpCooldown());
    }

    IEnumerator JumpCooldown() {
        // if jumped, wait for a second 
        if (Input.GetKey(KeyCode.Space) )
        {
            ball.AddForce(jumpForce * Vector3.up);
            yield return new WaitForSeconds(10);
        }
        // otherwise wait for a frame
        yield return null;
    }

[rocky canyon]

make it a child and scale that instead

[swift crag]

This starts a new coroutine every single FixedUpdate

[oak tapir]

how do i make it a child?

[swift crag]

These are child objects.

[rocky canyon]

u already have children.. u should know how..

[swift crag]

If you don't know what any of these words mean, you need to stop what you are doing right now and go use !learn

[eternal falcon]

:teacher: Unity Learn ↗

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

[rocky canyon]

• parent
• child
  • grandchild

[earnest shore]

oh i see. So I should start the courtine in start()? or is therre another way thats better practice

[swift crag]

Each coroutine individually checks if you hit space. If you did, it adds force, waits 10 seconds, and then ends

[swift crag]

That would not work either, since the coroutine would run once, then end.

Consider a coroutine that just resets a field back to true

bool canJump = true;

IEnumerator JumpDelay() {
  canJump = false;
  yield return new WaitForSeconds(3f);
  canJump = true;
}

[earnest shore]

i see

thanks!

[swift crag]

If you run this with StartCoroutine(JumpDelay()), it'll instantly set canJump to false, wait 3 seconds, then set it back to true.

[earnest shore]

yep

[gloomy nebula]

issue building? compiler is closed

[swift crag]

I don't know how you would "close" the compiler

are you talking about the console? your code editor?

[gloomy nebula]

yes thats what i meant sorry

[swift crag]

That doesn't do anything.

Look in the bottom right corner of your editor. There will probably be a blue bar with some text on it

e.g. "Compiling scripts"

[gloomy nebula]

lol, im just really tired sorry, brain isnt working and i just want to build this

[swift crag]

that means Unity is busy doing something

[gloomy nebula]

ive restarted unity

[swift crag]

well, you just interrupted it!

screenshot the entire editor window

[swift crag]

looks fine now

[gloomy nebula]

i press build, same error and this pops up for half a second

[swift crag]

Ah, then you're getting a compile error

Show the console.

[swift crag]

Always look at the first error

The other errors will just be "the build failed"

your code has a using directive for something in UnityEditor

None of that stuff exists in the built game

[rocky canyon]

red ❗ are a no-go

[swift crag]

It was probably added by mistake.

Try removing the using UnityEditor... line from the script.

[gloomy nebula]

vsc would usually tell me theres errors in the console with a big red notification, didnt realise i had errors since i didnt check, thats on me!

[rocky canyon]

yup, no worries

[swift crag]

The sneaky part is that this error only exists when the game is built (:

It's totally fine when working in the editor

It's (very very roughly) because of some code like this

#if UNITY_EDITOR
public class Oops { }
#endif

#if is used to conditionally include parts of a script

[gloomy nebula]

i havent got the using UnityEditor line

[swift crag]

this only includes the Oops class if UNITY_EDITOR is defined

[swift crag]

line 3

[gloomy nebula]

im so blind.

apologies haha

[elder raptor]

I don't understand why but my character randomly starts rotating around 360 degrees when I stop moving. Any idea why? Must be a simple issue but I've been coding for almost 20 hours now and I have burnt every brain cell 😔

https://hastebin.com/share/juticosaxu.csharp

[swift crag]

no prob (:

[gloomy nebula]

worked just fine, thank you so much

[remote osprey]

How can imake something like this work in unity?

List<GameEvent> events = data.BeginTurnCardEffects.Select(x =>
{
    ITarget target = null;
    if (x.needTarget) { target = GetTarget(); }
    return x.CreateEvent(data, target);
});

[elder raptor]

Nvm I figured it out, just added a rb.angularVelocity = Vector3.zero; in the else and it worked

[gloomy nebula]

why doesnt my icon change?

[verbal dome]

Did you build it again after changing it?

[languid spire]

Because that icon if used for the built game not the project

[gloomy nebula]

i deleted the old build and then built it again yes

[elder raptor]

Sometimes windows Caches the old Icon for some reason, happened to me once and a restart showed the new icon for me.

[languid spire]

did you not see the little check box?

[gloomy nebula]

the override one? i tried that

[gloomy nebula]

^ this, when i transferred to a usb it sorted it

[swift crag]

That's used to provide a specific icon on desktop platforms, so that would not be helpful here anyway

[stuck palm]

does changing base class script execution order change inherited clases script execution order?

[wintry quarry]

No idea but it would be good to know.

My guess is probably not.

[slender nymph]

if you use the DefaultExecutionOrder attribute, that should be inherited. i don't think that just changing the editor setting will do it though

[swift crag]

this reminds of a tangential thing: it'd be nice if there was a way to completely scramble all of your unity objects so that things with the same execution time now run in a different order

to help catch really weird execution order issues

[stuck palm]

are these just orders or like ticks or something

[eternal needle]

The numbering system? It's just arbitrary numbers used for order

[stuck palm]

ah i see

[wintry quarry]

I wonder which would catch more bugs more often:

• A random scramble
• Reversing the order

[swift crag]

Imagine someone randomly shuffling until the errors stop

Bogosort!

[stuck palm]

the discrepancy is getting shorter now

but its still there

not sure if this order is optimal

[eternal needle]

Or shuffle, see if theres still errors. If so, close the application. Quantum bogosort

[remote osprey]

What's the best way to enqueue events?

I feel like i'm reinventing the wheel a bit with my event classes

[eternal needle]

What do you mean best way? This sounds like you just want to store them whether that be in an array, list, queue, whatever, or even just all in one delegate.

[remote osprey]

Yes, but i'm implementing my own event classes

and it's been difficult

I'm watching a UnityEvent tutorial on youtube but i don't know if it has applications outside the inspector

[eternal needle]

Then share the difficulties. Queueing up events alone doesnt seem to be the problem

Unity events are pretty much just for inspector

Ok

i'm gonna take a dinner break then I'll come back with more questions 🙂

[queen thicket]

im have a button setup with a onclick but my function wont show up when i try to find it ik im prob jsut dumb but can someone help

[rocky canyon]

did u drag in a gameobject w/ the script or did u drag in the script itself?

[queen thicket]

wdy,

[rocky canyon]

did u drag in one of these

or one of these

[queen thicket]

yes i draggewd that one in

[olive osprey]

Drag the gameobject into the spot where it says none on the onclick function.

[rocky canyon]

thats wrong..

[rocky canyon]

u cant drag the script in there like that

u have to drag in a gameobject w/ the script attached to it

the script doesn't exist just because its in the project folder

[queen thicket]

thers no object to drag in another gameobject

[olive osprey]

@rocky canyon are you able to help me with my error im facing?

[rocky canyon]

the slot

[rich adder]

so put the script on a gameobject

[rocky canyon]

this one.. drag a gameobject in there

if u dont have a gameobject w/ the script make one

¯_(ツ)_/¯

[rich adder]

components need to be on a gameobject

[olive osprey]

youtube and google are great tools.

but they dont always work....

[rocky canyon]

yes they are, and no they dont

[olive osprey]

cause I cant find the fix to my issue lol

[rich adder]

you have to learn how to fix things yourself

isn't that the whole point?

[olive osprey]

sheesh

nice

[rocky canyon]

no, sorry i can't help you with this.. im not familiar with mobile or / ad type stuff sorry

[queen adder]

anyone know why this happens? was fine before but now its almost impossible to write code without writing over something else 😭

[rich adder]

press Insert on your keyboard

the game freezes up for a bit when i try to load from disk, is there a way to make this async or coroutine to let it load replays in the background?

https://gdl.space/eqatasopoz.cs

[rocky canyon]

amazing 🙂

[rich adder]

ReadAllTextAsync

ig

[verbal dome]

This? https://docs.unity3d.com/ScriptReference/Unity.IO.LowLevel.Unsafe.AsyncReadManager.html

[stuck palm]

unsafe? lol

why is it unsafe

[rich adder]

cause its lowlevel

[verbal dome]

Probably using unsafe code 🤷‍♂️

I just found it by googling "unity read file async"

[rich adder]

had no idea this existed

https://docs.unity3d.com/ScriptReference/Unity.IO.LowLevel.Unsafe.AsyncReadManager.OpenFileAsync.html

[stuck palm]

could i fuck something up with this method

public unsafe void

never seen that keyword before

[verbal dome]

This is worth trying too

[rich adder]

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

[stuck palm]

so it lets me use pointers

[queen thicket]

this is what imean @rocky canyon

[rocky canyon]

you need to restart ur editor / pc

somethings fkd up

[rich adder]

You cant put scene objects in a prefab

[queen thicket]

thats a script not a scene obkject'

[rocky canyon]

unless thats just bad screen recording im seeing

[rich adder]

you're not supposed to drag it from project folder..

[swift crag]

same; i haven't touched this before

[rich adder]

would love to test it with big file

[queen thicket]

and how do you mean that

[stuck palm]

does this i have to use async methods or can i put it in a coroutine or

[rich adder]

it needs to be on an Instance of a gameobject to run, thats how components work

no clue, my first time seeing this. the link i sent seems to be doing it inside Update so idk whats going on

[queen thicket]

What does that mean im very new

[rocky canyon]

https://user-images.githubusercontent.com/60554748/227689794-0f5b9380-7db1-4a99-91c5-0644e45e8cf3.gif

this is how u assign a script to an inspector slot

[stuck palm]

uncharted territory

interesting

[polar acorn]

https://unity.huh.how/unity-events/incorrect-assignment

[rocky canyon]

u dont drag in Apple.cs you drag in a GameObject w/ the Apple.cs script attached to it

as said 4 times already

[rich adder]

@queen thicket Scripts that are Monobehaviour are components. Components need to be on a gameobject to do anything.

[rocky canyon]

☝️ this

[queen thicket]

what i was poinng out was that it dosent show my function in the onclick thing id think thats what you guys are talking about it onbyl shows monoscript when i want it to show speedpotion functions to

[polar acorn]

#💻┃code-beginner message

[rocky canyon]

we know what we're talkin about..

[rich adder]

its because you're using the file from the project folder, and thats not correct

thats just a textfile by itself 🤷‍♂️

[polar acorn]

The text file containing the code does not have functions. An object with the script on it has the functions

[queen thicket]

ok well i was confused because before i had done it just like that and it worked perfectly

[rocky canyon]

Create a New GameObject

• Name it SpeedPotion or w/e
• Attach the speedPotion script to it
• Finally.. drag that gameobject you just created into the slot

[polar acorn]

No, you haven't

[swift crag]

press X to dougb

[rich adder]

wish had nitro still

[naive pawn]

dougbt

[polar acorn]

At no point could you ever drag a script object onto a UnityEvent to run a function defined by the script

[swift crag]

You've dragged in a reference to a script asset.

[naive pawn]

i gotchu

[swift crag]

This is like trying to drive the blueprint for a car

[queen thicket]

ok

[rocky canyon]

writing calligraphy w/ a squid

[rocky canyon]

you also can't reference scene objects w/ a prefab

unless that reference is Inside the prefab already

[queen thicket]

ok well then this tutorial im following is not doing a good job

[rocky canyon]

sooo.. you should put that gameobject u made inside the prefab.. and then try assigning it

[rocky canyon]

what tutorial are you following?

[queen thicket]

https://www.youtube.com/watch?v=OG7vHstkZqM

i did the first one aswell

[rich adder]

you probably followed it wrong

[stuck palm]

thank the lord for linq

.Last is easy

[polar acorn]

Where in this video did they drag in a script file to a UnityEvent?

[rocky canyon]

he made a prefab and dragged that into the slot

[queen thicket]

what did he make the prefab from?

[rocky canyon]

the gameobject w/ the script attached to it

[queen thicket]

ok ty for helping someone who has no brainpower what so ever

[rich adder]

careful how many times you run LINQ esp in unity

[rocky canyon]

https://youtu.be/OG7vHstkZqM?si=H9s7AR9KSOhi7F6n&t=336

watch from 5:36

[stuck palm]

why? im only running it like once a scene anyway so

[rocky canyon]

his script is ON the same gameobject

as said here

[rich adder]

ooh thats fine then. I mean things like Update or consant operation like that

for loops are always best in that case

[queen thicket]

wait nvm my code is (idk if i can swear but you know what i mean)

[verbal dome]

.Last is fine, it shouldn't generate garbage if that's what you mean

But yes one should be wary of Linq methods

[rich adder]

just mean LINQ in general but yeah .Last is not biggie

[rocky canyon]

||ur code is Fucked up eh? ||

trying backing up, and taking it a bit slower.. and pay attention to every move he makes

[queen thicket]

nah its just ||shity||

[rocky canyon]

it happens...

we all write shit code at first

it gets better the more you practice

[queen thicket]

this si my problem if you need the error its NullReferenceException: Object reference not set to an instance of an object

[final kestrel]

Working on inventory is fun til you try saving and loading

[rocky canyon]

ohh.. that IDE doesn't look too configured to me..

[queen thicket]

not at all lmao

not at my home pc

just decided to pull the repo

[rocky canyon]

eeeek

would help to have it configured !ide it doesn't take long

[eternal falcon]

💡 IDE Configuration

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

Select one:

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

[queen thicket]

ikr it sucks having no intelliscense

[rocky canyon]

line 15.. theres a Null Reference..

somethings not assigned correctly

[rich adder]

if you did things correctly your items would already be the proper formatted objects

[dusty shell]

pushing my entire project folder to git is normal right?

[rocky canyon]

saving and loading is the best thing i ever done

[swift crag]

Not everything in it

notably, the Library folder is excluded

[final kestrel]

I also followed a tutorial and dont have the slightest clue of what information to keep T-T

[swift crag]

!vc

[eternal falcon]

Using version control in Unity

Unity Version Control

• Getting started

Git

Get the latest .gitignore file from here. It should be placed at the root of your Unity project directory.

[queen thicket]

are you using the unity .gitignore template

[dusty shell]

sigh

[dusty shell]

nah i just commited the folder 😦

[rocky canyon]

if u push ur Library folder get ready to wait a few hours

[rich adder]

thats probably why. Once you build your own system by scratch by yourself, you will know exactly how to serialize it to a file

[dusty shell]

Lost all my old projects so it seemed logical at the time

[swift crag]

if that was your first commit, i'd just nuke the .git folder, re-init the repository, add the .gitignore file, and commit again

it's probably easier than rewriting the commit in that situation

[final kestrel]

Yep you're right

[queen thicket]

can you tell what it is from the video i dontknow how to do it

[dusty shell]

sure

[rocky canyon]

    public void Save()
    {   
        // ERROR CHECKING
        if(!Directory.Exists(Application.persistentDataPath))
            Directory.CreateDirectory(Application.persistentDataPath);

        // create json // pretty print cause line breaks for readibility
        string jsonObj = JsonUtility.ToJson(_saveData,true);

        // write data
        File.WriteAllText(saveFilePath,jsonObj);
        FlashSaveActivityIcon("Save System: JSON-W");
    }``` w/ JsonUtility ofc 😉

[rich adder]

JAYY SON

[naive pawn]

here, use this https://github.com/github/gitignore/blob/main/Unity.gitignore

(rename it to just .gitignore in the root of your project)

[queen thicket]

im good enught with file handeling and stuff and i could make some devius spegethi code but i jsut dont know the unity stuff

[dusty shell]

I remember the hassle of learning this for pygame ( I don't remember shit)

[swift crag]

Serialization requires you to turn your giant blob of C# objects and references into a neat little file

It is non-trivial.

[rich adder]

its all in one.

Null reference are not "unity stuff"

[rocky canyon]

i cant even find a speedPotion.cs in his tutorial

i skimmed the first one and the second one

[wooden socket]

hey guys! My game is pretty close to completion from what I can tell. I have a really dumb question and I know I asked it before kind of but im still confused a small bit

[queen thicket]

its not in his tutorial i made it myself 😢

[shell sorrel]

there is no magic bullet for good save systems, you really need to consider what data needs to be saved vs just reconstructed state

[wooden socket]

okay so, I want to take the value of lives from another script and put it into a different script in an if statement. do I use parenthesis and if so where.

[rocky canyon]

theres only two possibilities.. either you dont have a PlayerMovement assigned (which i don't see it getting assigned anywhere)

or theres no variable called runSpeed

[queen thicket]

wait what do i assighn it as

[rich adder]

if statements require parenthesis yes..

[rocky canyon]

make it [SerializedField] priivate PlayerMovement movement;

[rocky canyon]

and then you can drag in the component in the speed script

[queen thicket]

== 0

[rich adder]

= is for assigment

[wooden socket]

I also put public LivesManage lives; at the top

OH

[queen thicket]

lmao

[rocky canyon]

and u sure ur comparing the right thing?

shouldnt it be lives.lives == 0

rather than the Type

[eternal needle]

Please do some c# basics first. This isnt even the same thing

One is a variable of type LivesManage and the other is a number.

[wooden socket]

oh wait

i gotta make it an int

[rocky canyon]

my heads about to explode

[wooden socket]

im sorry 😭

[rocky canyon]

its not you in particular

[wooden socket]

okay good lol

[queen thicket]

i get errors cuz im stupid [SerializedField] private PlayerMovement movement; with this

[shell sorrel]

Also need to compare not assign, and is it static or a instance field

[rich adder]

you can't make everything static , you have to learn how to make references and connect them

[mild onyx]

ok this time i swear i followed the tutorial exactly and i have 6 problems from 3 lines of code

[wooden socket]

okay ill look into it rn

[rich adder]

https://unity.huh.how/references/serializing-component-references

[wooden socket]

I FORGOT ABOUT THIS SITE

THANK YOU

[rocky canyon]

can u screenshot the script

[queen adder]

Trying to add a score system to my game. Does anyone know what the errors mean? 😭

[rich adder]

also what is the error , screenshot

[polar acorn]

You can't have two things with the same name

[rich adder]

naming a method "Score" is strange..

[rocky canyon]

my bad.. its [SerializeField]

ur IDE woulda told u taht 😛

[summer stump]

Methods make more sense when named as actions. Maybe AddScore?

[rich adder]

method name should be similiar to an action or something

[rocky canyon]

no d on the end

[queen thicket]

it dosent 😢

[rocky canyon]

why don't u configure it real quick?

[queen thicket]

erm what the sigma its still giving me the error 💀

[rocky canyon]

look

[rich adder]

you need a configured IDE if you plan on getting help

[rocky canyon]

now u need to assign it man

see the None u need to put the gameobject in there that has the PlayerMovement script

and by now u should know how reference work (sorta)

[queen thicket]

ok my dumb ass frogot about that one cheif

[rocky canyon]

very important

you'll do it every single day of coding

[rich adder]

where did you see using () for attributes?

[naive pawn]

attributes use brackets, not parens

[rocky canyon]

( pretending to be [s

shameful

[mild onyx]

huh

[queen thicket]

im so done right now 😡

[mild onyx]

not a clue what that is

[dusty shell]

can you avoid this by setting requireded components?

[rocky canyon]

mine... correct

[rich adder]

the thing you're using..

[rich adder]

its an Attribute

[rocky canyon]

yours wrong

[rich adder]

Where did you see to use (

[mild onyx]

im using like 50 things

[rocky canyon]

absolutely.. he's struggling so i wanted to make it simple

but u should assign it internally in the script when u can

[rich adder]

I just told you what, its called an Attribute

[naive pawn]

maybe he's talking about the thing you're having problems with

[mild onyx]

I DONT KNOW WHAT THAT IS

[rich adder]

had you bothered googling it you would know what it is

[dusty shell]

Try watching someone build a project and following along

[rich adder]

https://docs.unity3d.com/Manual/Attributes.html

[mild onyx]

Thats exaclty what i did

[rocky canyon]

ohh you mean like @dusty shell

[naive pawn]

right, but you used parens () instead of square brackets []

[rich adder]

I dont thinkk they even understand why they need to use brackets..

[naive pawn]

you need [AttributeName], not (AttributeName)

[rocky canyon]

ya, if the script was meant to be on the same gameobjec thats fine @dusty shell

[naive pawn]

(that's a separate convo)

[rocky canyon]

but his script was on a different gameobject

[rich adder]

oh wops myb @rocky canyon

[mild onyx]

mf maybe a 30" monitor still wasnt big enough for a quartered screen

[dusty shell]

yes

[mild onyx]

thank you that guy

[queen thicket]

im 😭 rn

[polar acorn]

"Hey man what is this thing?"
"That's called an 'Attribute', here's a picture of it"
"I DON'T KNOW WHAT AN ATTRIBUTE IS SIR I AM NOT A COMPUTER PERSON"

[naive pawn]

christ, calm down lmao
google exists for a reason, there's a ton of info for you out there

[rocky canyon]

ya, but i dont think his Movement script should be on his speedPotion

[dusty shell]

don't just copy their code tho

[rocky canyon]

doesn't make much sense for this situation

[rich adder]

camelCase classes 😢

[queen thicket]

im setting the speed varibal

[rocky canyon]

i was talkin to JoJo

[queen thicket]

ive been coding for 12 hrs straight im a little bit tired rn

[rocky canyon]

you should rest

for real

[mild onyx]

the studio was saying tuple so i assumed thats what it was

[queen thicket]

na

[rich adder]

time to take a break then

[queen thicket]

i gotta get it done

[rocky canyon]

lol.. okay then

[naive pawn]

right, because you wrote that instead of an attribute, which is why it was wrong

[polar acorn]

Right, because what you wrote was a Tuple. With parenthesis. Which don't go there

[queen thicket]

otherwise my dad will go and get the milk

[rocky canyon]

is that some gen z cryptic lingo?

[rich adder]

I remember my first beer too

[eternal magnet]

guys is unity easy to code games in?

[rich adder]

only if you can learn C#

[remote osprey]

The main thing is, I'm using the Command pattern in order to make my card game events because I initially thought that C# events aren't synchronous and I also thought that it would make my code "cleaner" but it's been so difficult to implement that I've started looking to other resources and I also realized that using Command or not is just a design decision.

[naive pawn]

depends on what you consider "easy"

[rocky canyon]

if u have a moderate IQ level its prettty ez

[eternal magnet]

i can becouse why not

[queen thicket]

no my dad said he would leave if i dident finish this project today

[rocky canyon]

lmao.. craziness

[naive pawn]

it's a skill, you have to actually put effort into it

[rich adder]

then depends on how quick you learn and whatnot. there is no gauge for us to say

[eternal magnet]

i learned a bit of rust in week

[rocky canyon]

its all RELATIVE 😉

[eternal magnet]

ok so what unity version should i start coding at?

[remote osprey]

And I also realized that undoing commands isn't something common to the game that I want to make, so I'm not finding many reasons to keep developing my Command pattern.

@eternal needle

[rich adder]

2022

[eternal magnet]

60000.0.7f1 or 2022.3.34f1?

[rocky canyon]

the latest LTS version

[eternal magnet]

how can i change install loction, arch linux

[rocky canyon]

60000 could have issues u might not be able to deal w/ learning

[rich adder]

through the hub

[eternal magnet]

would hdd work?

[rocky canyon]

sure

[rich adder]

yeah but ill prob b slow

ssd always better

[rocky canyon]

not too bad @rich adder

[eternal magnet]

can i later move it to ssd?

[rich adder]

oh interesting

[olive osprey]

🖕 I figured it out thanks for the help.

[eternal magnet]

my dad said if i started learning programing that he will buy me better gpu and bigger ssd

[rocky canyon]

only when I load initially it may take longer than my SSD versions

but once its loaded up its not noticeable to me.. from my SSDs

[rich adder]

ookk lol No idea why you took that statement so personally

[remote osprey]

Although, at this point, I could keep at it just for the sake of finishing it.
@eternal needle

[rocky canyon]

daaamn, he went savage on u

[rich adder]

time to get going then

[eternal magnet]

do i need windows to test games in windows or testing linux version is enough?

[rocky canyon]

depends on who ur target platform is for

[eternal magnet]

pc in general

[rocky canyon]

then u probably want to test on windows from time to time

if u can

and Mac.. but i can't even do that

[eternal magnet]

i can if the games will work on 10 years old gpu

[rocky canyon]

my friends aint rich enuff

[rocky canyon]

im using a 5 year old GPU

no issues

[eternal magnet]

just buy rx 580 and hackintosh

[rocky canyon]

gross

[eternal magnet]

same the gpu i use in linux is 5 years old

[rocky canyon]

lol.. sorry im just not a Mac fan

[eternal magnet]

but my windows gpu is 10 years old i have gpu passthrough

[rocky canyon]

i don't care if my games work on mac

[eternal magnet]

its not about would they work on mac

its about arm

windows is moving to arm as well

and i only have x86 pcs and laptops

[rocky canyon]

not me im not

[eternal magnet]

i wish it was easy to run arm windows games on android

as how easy it is to run x86 windows games on android

[rocky canyon]

i dont understand really why you'd want to run any games other than mobile games on android

just get a Surface and be done with it

[eternal magnet]

how easy is it to port games to android?

it would be very intersting to make android game like the ads you get but at the same time have pc version and maybe steam version

[naive pawn]

😔

[eternal magnet]

technly i can run mac os but without gpu

[rocky canyon]

i might make an exception if someone paid me enough 😄

[rocky canyon]

relatively simple.. you'd just need to change the inputs.. and nerf the graphics a bit..

if u use the new input system u can probably make an input action map that would work for both PC and Mobile

[naive pawn]

i mean couldn't you just add web support lol

[rocky canyon]

id do that for ya guys 🙂

[eternal magnet]

flash player was good

[rocky canyon]

webGL builds are harder for me than regular builds

hard af to get them working as good as good as standalone build

compression issues, graphical glitches / artifacts / weird shader issues.. or just incompatible

[frank zodiac]

so is triggered when i press the key or is it started?

im confused abt this new input system

[rocky canyon]

performed i think

[frank zodiac]

isnt performed when you press and release?

[rocky canyon]

possibly.. im still learning too

[frank zodiac]

lol we all are

[rocky canyon]

i need to debug my test class and see for sure what happens

[frank zodiac]

thanks for the help

[rocky canyon]

i didn't really help but no problem 👍

lol

[wind raptor]

[Serializable]
public class SomeClass

    public SomeClass SomeClassInstance = new SomeClass();
}

[wooden socket]

okay so im still a bit confused. in a script that has the lives counter, I want it to play a transition that I made in a different script when lives == 0

[worn egret]

Hello i need help, I try to do that my player slide on the wall :
if (isSliding == true)
{
rb.velocity = new Vector2(rb.velocity.x, Mathf.Clamp(rb.velocity.y, -wallSlidingSpeed, float.MaxValue));
}

I know that isSliding is true but my player drop on the floor normaly, my rb.velocity is false ? (the if is on void update)

[swift crag]

For a Button-type action, it fires when you pass the acuation threshold (so, when the button is sufficiently pushed)

[frank zodiac]

ohhh i see

thanks

[swift crag]

For a Value-type action, it fires whenever the value changes. It might also fire when the input returns to zero (I don't use events for value type actions)

I just directly read the value as needed.

[wooden socket]

I know I can reference the transitionController script, but Im getting this error

[naive pawn]

when it's constructed

that's its constructor

new Classname() is the constructor call

[frank zodiac]

bool interactable;


public void OnInteract(InputAction.CallbackContext callbackContext)
{
    if (callbackContext.started && interactable)
    {
        Debug.Log("Interacting");
    }
}

private void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.CompareTag("Interactable"))
    {
        interactable = true;
    }
    else
    {
        interactable = false;
    }
}

theres nothing wrnog with this code but the interactable bool wont set to true

[swift crag]

well, if you enter another trigger, you'll get interactable set to false

[dense plume]

Make sure the tag exists

[swift crag]

even if you're still overlapping the interactable trigger

[dusty shell]

Does unity have like complex assets?

[swift crag]

that seems wrong

[swift crag]

I don't know what that would entail

[dusty shell]

Like movement script assets?

[rocky canyon]

yes

dozens

[frank zodiac]

it does

[dusty shell]

Complex ones?

[rocky canyon]

i recommend KCC

[swift crag]

Oh, like stuff from the asset store

[frank zodiac]

there are only 2 objects in my scene though

[naive pawn]

what do you mean by "complex" though

[rocky canyon]

https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131
i use a paid one.. but this one is almost as good

chcek it out

[dusty shell]

This is probably not a good example but it’s the only thing that comes to mind, apex for example

[naive pawn]

...the game?

[rocky canyon]

no.. u wont find those unless there are some paid ones

u have to take a base controller and build it up

[wooden socket]

wait

thats a bad ss

[dusty shell]

Yeah the movement in apex

[wooden socket]

lemme send my code

[rocky canyon]

https://assetstore.unity.com/packages/tools/animation/traversal-game-creator-1-179526 you'll find some that might have some of the features..

but no.. u wont find a 1:1 apex controller

[dusty shell]

Yeah I wasn’t expecting that but something similar is quite nice

[wooden socket]

what could I use instead of void?

[naive pawn]

WaitForSeconds needs to go in a coroutine

i don't think messages can be coroutines

[shell sorrel]

you can't the message must have a void return type

[wooden socket]

ah true

lemme make a coroutine

[rocky canyon]

nothing.. thats what OnTriggerEnter2D is

[shell sorrel]

best you can do is define a seperate coroutine and start it within that message

[polar acorn]

You can't put a yield return in a method that returns void

[shell sorrel]

would keep most of the code in the OnTriggerEnter and just move the SetTrigger, WaitForSEconds and load to a coroutine and start it from there

[rocky canyon]

OnTriggerEnter --> StartCoroutine(TriggeredCoroutine());

[wooden socket]

so I out the StartCorotine instead of Collider2D and other?

[rocky canyon]

u could pass those into the coroutine if u needed too.. but what passerby said is what i was thinking..

[wooden socket]

okay ill do thagt

[rocky canyon]

    void OnTriggerEnter2D(Collider2D other)
    {
        StartCoroutine(HandleTrigger(other));
    }

    IEnumerator HandleTrigger(Collider2D collider)
    {
        yield return new WaitForSeconds(1f);
        Debug.Log(collider.name);
    }```

[rocky canyon]

like

[wooden socket]

okay now do I type yield HandleTrigger?

[naive pawn]

wdym

you don't yield the coroutine

[wooden socket]

how would I call the HandleTrigger in the OnTriggerEnter function

[sage mirage]

Hey! Is that code you wrote because seems interesting for interacting with doors and items like I understand right because I never used that method

[naive pawn]

normally

and then start it as a coroutine

[frank zodiac]

its really basic interacting methods

[wooden socket]

wait lemme show u what I have

[naive pawn]

https://docs.unity3d.com/Manual/Coroutines.html

[frank zodiac]

and yeah i did right it

[naive pawn]

@wooden socket go check how coroutines work

[wooden socket]

ok

[sage mirage]

Is it for a horror game?

[frank zodiac]

nah

[sage mirage]

I am currently making a short psychological horror game, and I really have to watch tutorials on how to make interactable items and doors etc

[frank zodiac]

thats cool

good luck man

[stuck palm]

hoq can i make attributes?

like [Attribute]

i think thats what its called

[shell sorrel]

they are easy to make but using them requires using reflection

https://learn.microsoft.com/en-us/dotnet/standard/attributes/

for the most part its as simple as making a class that extends from System.Attribute

your constructor args become the args you can pass into the attribute on usage

[swift crag]

making them is trivial

but yeah, using them requires reflection

[shell sorrel]

using them requires more work

[swift crag]

accessing the constructor args is also mildly confusing

i thought you could just assign to fields on the class at first

[shell sorrel]

whats confusing, i always just have constructor args that have it to set a bunch of readonly fields

i use them in a few cases in my project, like register action types with the behaviour editor

and for stuff like building the debug/cheats menu

[swift crag]

I wonder if I'm just mis-remembering another error I made

because I'm looking at https://learn.microsoft.com/en-us/dotnet/standard/attributes/writing-custom-attributes and that looks normal

[shell sorrel]

can get the attribute info back easy with either .nets GetTypes GetMethods etc

or via unitys TypeCache if its for editor stuff

[stuck palm]

what is reflection

[shell sorrel]

a meta coding feature

[swift crag]

reflection lets you ask questions about types

like "what fields does this type have?"

It's how Unity calls things like Update

[shell sorrel]

lets you do stuff like see what fields a type has, or what methods it has and invoke one etc

[swift crag]

notice how it's not protected virtual void Update() or something

as long as you have a method named Update, it works

[shell sorrel]

reflection is not very performent

[swift crag]

I guess that's the simplest way to explain it: accessing things by name

[shell sorrel]

its best to avoid in alot of cases

[swift crag]

It also ruins static analysis

"who calls this method?"
"I DON'T KNOW"

speaking of, pro tip

if you do need to use a method name, do this:

[shell sorrel]

yeah my only case of invoking via it, is for cheat menu, but since i use rider i can use its attributes

[swift crag]

Invoke(nameof(Foo), 3f);

[shell sorrel]

    public class CheatAttribute : Attribute {

and tell the IDE this means implict use

[swift crag]

neat

[shell sorrel]

all of my other reflection usages are editor time only, and for tooling

[swift crag]

This is much better than Invoke("Foo", 3f)

My main use of reflection is a horrifying class that checks for missing references

            while (parentType != typeof(object) && parentType != typeof(MonoBehaviour) &&
                   parentType != typeof(ScriptableObject))
            {
                fieldInfos.AddRange(parentType.GetFields((BindingFlags)(-1)));
                parentType = parentType.BaseType;
            }

yum

[shell sorrel]

but yeah my cheat menu builder uses a ton of it and is complciated since it needs to build ways of setting up the proper UI per type, and for executing methods with args and passing stuff to properties

@stuck palm what is your usecase, and is it wanted on types, or fields or methods

[stuck palm]

oh i wa sjust curioous lol

dont actually plan on making any

[shell sorrel]

ah yeah then the article i posted should be good, but also look at the TypeCache in unity, it has some stuff realted to how unity does it in editor

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

also
https://docs.unity3d.com/ScriptReference/PropertyAttribute.html
for cases where you want it for custom property drawers based on attribute

think of things like the Range(0f, 1f) etc

[final kestrel]

If you could rate... How hard is integrating inventory system with save load system for beginners like me? I started to question if I have negative iq or something

[shell sorrel]

Without much experience programming hard. But things get easier at a fast rate as you gain experience

[swift crag]

inventory systems and serialization can be remarkably difficult

[eternal magnet]

why does default loction has to be in /

[swift crag]

it gets easier if you simplify your design, such as by...

• having a fixed set of items (more like "key items" in Pokemon, for example)
• having non-stacking items
• keeping the items simple (no upgrades and modifiers)

[eternal magnet]

i only have 120gb ssd it cant fit anything

it become 0bytes free from unity packages

[final kestrel]

Thank you for your responses. I was just curious how you guys see it.

[eternal magnet]

changing loction redownloads what it has downloaded

[swift crag]

i mean...everything has to be in /

did you mean to type something else

[final kestrel]

Yeah like things got real complicated when prefabs and scriptable objects got involved 😄

[swift crag]

I am exploring that kind of thing now

I have around three years of Unity experience and a decade+ of general programming experience

[final kestrel]

cos what I understand from serialization is that I have to use the most basic types to be able to serialize them.

[swift crag]

You have to be able to go from your game data (which is very very easy to make complicated) to something you can write to a file

That's why key items are relatively easy. You could even just write a list of item names.

[remote osprey]

nothing is too hard!

[eternal magnet]

i dont have space in / right now maybe later when i buy 1tb ssd

[remote osprey]

You only need consistency and patience.

[wooden socket]

collision count is in another script

[remote osprey]

Don't worry, I'm a total begginer at Unity and I've been feeling overwhelmed since I started it

You got it!

[wooden socket]

how can I solvle this error 😭

[swift crag]

/ is the root of your filesystem. everything is, by definition, inside of /

I see that you're trying to point the download cache to /mnt/hdd/...

[swift crag]

well...create the variable

[final kestrel]

Item names you mean for identification?

[swift crag]

Right.

[wooden socket]

does this look good>

WAIT

[final kestrel]

Why do people keep their keys and values in seperate lists instead of dictionaries btw?

[wooden socket]

i think I fiixed it

[naive pawn]

unity doesn't serialize dicts, that might be why

[remote osprey]

Not everyone does that, I don't at least.

[eternal magnet]

i really want to learn unity, its my dream to create game

[final kestrel]

but newtonsoft's json serializer does it right?

[wanton crow]

if you have the programming experience, i would go for a manual serialization strategy,

1. create a map somewhere of keys to prefabs
2. when saving, loop the items and write the keys to a file
3. when loading, loop the keys of the file and instantiate the prefabs by looking up the key in the prefab map
4. bonus: assume all the values not in the save file are "default" prefab values and save the "changed" values to the save file to apply them to the prefab after loading

[swift crag]

That's a separate thing.

[wanton crow]

thats how i do it anyway

[swift crag]

Unity serialization lets you store data in scenes and prefabs and assets

[naive pawn]

i wouldn't recommend it, but it's a workaround ive seen proposed
i'd recommend a list of structs instead

[final kestrel]

OO so thats a different thing okay

[swift crag]

Json.NET is used to turn C# objects into JSON, and then from JSON back into C# objects

They both do similar things -- turn objects into data and back

You need something to be Unity-serializable if you want it to appear in the inspector

[wooden socket]

i keep getting null reference exceptions

[swift crag]

well, fix them!

find out what is null, then figure out why it's null

[final kestrel]

Okay so that kind of explains why I got confused about ISerializationCallbackReceiver. Its for unity not c# serializer?

[wooden socket]

well, null is an object isnt referenced

but idk how thats possible

heres line 25 which is what its talking about

[final kestrel]

I think it would work after reading game data from json too though

the OnAfterDeserialize method I meant

[wanton crow]

if you are doing a load/save game system, just note that it is completely separate from the Unity scene editor serialization

[polar acorn]

borderController is null

[wanton crow]

the two are not related other than that it can both involve serialization

[final kestrel]

damn okay this makes things clearer now

[swift crag]

It's used to manually fix up an object after Unity deserializes it -- so, after it's loaded from data

The example in the documentation is for reconstructing a dictionary out of two lists

Unity can't directly create the dictionary for you

But, given the lists, you can figure out the rest

[final kestrel]

Ah okay. Thanks. I must do more research on this

Shit is hard when you dont even know what you dont understand hehe

[wanton crow]

True Knowledge 😁

[wooden socket]

well yea, but idk how to fix it

lemme look into it first

[polar acorn]

Set it to something, instead of having it be nothing

[wooden socket]

well hmm

i did this though

[polar acorn]

So you've declared a variable. Where do you put anything in it

[wooden socket]

would i put the value in it in the same line?

[polar acorn]

Which BorderController do you want this variable to hold?

[wooden socket]

a value called collision count

wairt

nvm

idk what to do

[polar acorn]

Well, which BorderController do you want this variable to hold?

You never answered that

[wooden socket]

BorderController is the other script

[polar acorn]

Okay but that script could be on thirty trillion objects for all this code knows

[wooden socket]

I want the value called collisionCount to be passed here

[polar acorn]

which one do you want

[wooden socket]

collisionCount

[polar acorn]

Which specific instance of the BorderController class do you want your variable borderController to hold

[queen adder]

yoo, My score text is below my road sprite for whatever reason. Im unsure on how to fix it. My Score canvas is higher on the hierarchy also.

^ when I drag the 0 down it goes under the road

[swift crag]

show the inspector for the canvas and for the road object

also, this is not a code problem

so show them in #📲┃ui-ux

[wooden socket]

there is no instance

its just a script

[swift crag]

Show us the BorderController script.

[wooden socket]

my bad ill ppost them theere now

[wooden socket]

https://gdl.space/oduhucujas.cpp

[polar acorn]

Then it does not exist

If there's no instance of BorderController then it is completely identical to if you had simply deleted the script

[eternal magnet]

hm i was going to do Godot

but unity seems easier

[polar acorn]

A script is merely a blueprint for an object. Until you actually make one, the script is worthless

[wooden socket]

OH i gotta make an object

mb

[swift crag]

If there are no instances of BorderContorller, then your field will, unsurprisingly, always contain null.

[wooden socket]

but its on a object

[polar acorn]

what is

[wooden socket]

the script

borderController
