because it's trying to do 50 fixed updates per in-game second

[dusty silo]

I am using this https://gdl.space/wuvufeliqo.cs triangulator that I found online and edited slightly. When I run the code, I get the following error:
"Failed setting triangles. Some indices are referencing out of bounds vertices. IndexCount: 24, VertexCount: 0"
There isn't a code problem with the triangulator, but it seems to be doing something wrong. The problem is that it is completely opaque to me. Can anyone here see if & where something is going wrong?

[swift crag]

Scaling fixedDeltaTime based on the timescale means that it's always doing the same number of fixed updates per real world second

[brazen canyon]

Hey guys, I need a little help
Here I have this method
This method spawns an item in a position that's empty, but I want it to spawn item a few second after that position is emptied.
So I use Coroutine
But it doesn't work, the new items kept being spawned immediately
Please help, where do I have to put the yield return ?

[swift crag]

Show the entire script.

    }
}

[swift crag]

The code you showed looks fine -- it waits for either 3 or 4 seconds, then calls SpawnBricks

You're starting a coroutine every single frame

So there are tons and tons of coroutines running all at once

Perhaps you wanted to start it once when the brick was destroyed

(note that if you want a range of 3 to 5 seconds, you should do Random.Range(3f, 5f))

if you give it two integers, you get an integer in the range [low, high)

excluding the high value

[swift crag]

Where exactly does the error come from?

You should be getting a line number.

[dusty silo]

It's coming from UnityEngine. There is no error in the triangulator, just in the array that it spits out

[dusty silo]

public void render() {
        Mesh mesh = new Mesh();
        mesh.triangles = new Triangulator(_points).Triangulate();
        mesh.vertices = _points.ConvertAll(p => new Vector3(p.x, p.y, 0)).ToArray();
        mesh.uv = _points.ConvertAll(p => new Vector2(p.x / (MAX[0] - MIN[0]), p.y /(MAX[1] - MIN[1]))).ToArray();

        GetComponent<MeshFilter>().mesh = mesh;
    }

It is being called line 3 of render()

[native seal]

right now im creating all my data in a static class with static readonly dictionaries, is this a fine way to do it?

for example, all the tiers for each stat along with its weight, etc that can roll on an item

[swift crag]

Ah, wrong order

You need to assign vertices first

[swift crag]

You don't have any vertices yet, so Unity throws an error when you assign the triangles array

It immediately tries to validate the mesh when you do that.

[rocky canyon]

i'll have to find out where..

[swift crag]

right there #💻┃code-beginner message

[rocky canyon]

i'd rather pitch the volume up and down... than scale the timescale.. not sure whats going on

[swift crag]

it's two differeent things

[rocky canyon]

ya, sadly i dont understand what thats doing..

[swift crag]

It's setting a mixer parameter based on the time scale

I presume audio sources are reading that parameter to set their speed parameter

Completely separately, it's computing a fixedDeltaTime value based on the current timescale

[rocky canyon]

        void FixedUpdate() {
            // Set the fixed update rate based on time scale
            Time.fixedDeltaTime = Time.timeScale * initialFixedTime;
            fixedTimeFactor = 0.01f / initialFixedTime;
            inverseFixedTimeFactor = 1.0f / fixedTimeFactor;
        }```

this part eh?

lol. math

[swift crag]

Yes. I dunno what fixedTimeFactor and inverseFixedTimeFactor are used for

But that's what the first line is doing.

[rocky canyon]

time.. and math..

codes trying to softlock me

[dusty silo]

That fixed it, thanks

[brazen canyon]

Yes it worked
Thank you so much
Even though my code is an absolute mess right now :)))))

[swift crag]

Each time you call StartCoroutine, you're giving your MonoBehaviour an enumerator

By default, the enumerator gets resumed once every frame

so you had like 100 RespawnBrick enumerators all running

when an enumerator being run as as coroutine yields WaitForSeconds, Unity..waits for that many seconds!

then it resumes the enumerator again

and in this case, it calls SpawnBricks

[rocky canyon]

In simpler terms, this script ensures that when you want time to go faster or slower in your game, it doesn't just affect how things look or sound but also how the physics and other calculations happen. It keeps everything in sync, making sure that when time speeds up, everything speeds up, and when time slows down, everything slows down. This can be useful for creating slow-motion or fast-motion effects in your game. I had chatgpt ELI5 lol..

that might actually be fine to mesh w/ my prototype i already have..

the only thing i do is pause Time w/ time Time.timeScale

currently thats the only thing i do

[swift crag]

well, it's not that it makes physics run slower or faster as the timescale changes

that already happens

it keeps the number of physics updates per real-world second constant

[rocky canyon]

okay. i think i understand it now.

i usually stay away from time.. but this seems to be a dependency

[swift crag]

an enumerator being the thing that RespawnBricks returns! An enumerator "pauses" each time it hits a yield until someone resumes it

that's how coroutines work: your method does some work, then hits a yield and takes a break until Unity resumes it later

[rocky canyon]

okay I did a sample run.. the TimeMaster script doesn't negatively affect my existing code 👍 thats a good thing.

soo from what ive gathered from you and other research this basically is just a supplementary system.. that basically does what unity already does..

just a bit more

[swift crag]

This is all that it does.

By default, the number of physics updates is consistent per in-game second

[devout flower]

Hi, i don't have a particular problem but i'm just curious

I notice that you're emphasizing "in-game"

Is there a difference between ingame second and real-life second?

[swift crag]

Right.

Time.time measures how much time has passed when you take the timescale into account

[devout flower]

Ohhh

Interesting

[swift crag]

Time.unscaledTime ignores that.

It, along with Time.unscaledDeltaTime, are useful for things like UI that shouldn't depend on the timescale

(well, in-world UI should probably care about the timescale!)

[devout flower]

So when you change the time scale, let's just say from 1 to 0.5, then the number of physics update will be halved?

[swift crag]

The number that happen per real-world second, yeah

[devout flower]

Ah okok

That's useful to know for future projects

[swift crag]

Assuming the player isn't providing any inputs, this means that changing the timescale shouldn't change the outcome of physics

[devout flower]

Ah i see

[swift crag]

It won't run more simulation steps with a smaller timestep for each one

And, conversely, if you crank up the timescale, you don't get fewer, longer physics timesteps

[devout flower]

Before, I thought it would just magically know to make the physics simulation run at the same speed, but do less things

[swift crag]

when I set my game's time scale to like 50, I get dozens of FixedUpdate calls per second

[devout flower]

Wow

[swift crag]

yeah -- the important thing is that Time.fixedDeltaTime does not change as the timescale changes

[devout flower]

Dang

[swift crag]

so, by definition, we must run fewer physics updates per real-world second when the timescale is less than 1

[devout flower]

I see i see

[devout flower]

Does Time.deltaTime?

Wait imma be back in 3 min

[swift crag]

It does, yes. Hence Time.unscaledDeltaTime for when you don't want to factor in the timescale

[devout flower]

Oh i see

So if I was moving an object by adding to its position (times Time.deltaTime), I shouldn't multiply by Time.timeScale as well?

[swift crag]

Yeah, don't factor in Time.timescale

I guess you could do Time.unscaledDeltaTime * Time.timescale, but that'd be a bit silly :p

[charred heart]

Hi, I'm trying to run a coroutine from a non-monobehavior class. The problem is that coroutine only triggers once, no matter how many times I call it. This line yield return StartCoroutine(_currentAction); only run once.

private Action _callback;
public void SetGameEvent(IEnumerator currentAction, Action callback)
{
    _currentAction = currentAction;
    _callback = callback;
}

public void StartEvent()
{
    if (_currentAction != null)
    {
        StartCoroutine(StartEventCoroutine());
    }
}

private IEnumerator StartEventCoroutine()
{
    yield return StartCoroutine(_currentAction);  /// this 
    _callback?.Invoke();
}```

[swift crag]

_currentAction is an enumerator

once it's done, it's done

[polar acorn]

You'd need to make a new IEnumerator each time

[swift crag]

StartCoroutine(_currentAction) will see that you gave it a coroutine that's exhausted and immediately throw it out

[polar acorn]

It's a bit complicated, but you could take in a function that returns IEnumerator and then invoke it

[swift crag]

indeed -- maybe you can store a System.Func<IEnumreator>, which is a function that takes no arguments and returns an IEnumerator

StartCoroutine(enumeratorSource());

[polar acorn]

Yep, that's the one. I always have to look up between Action and Func which is the one that has parameters and which is the one with return values

So, instead of taking IEnumerator and passing it SomeFunction(), you take a Func<IEnumerator> and pass it SomeFunction

[swift crag]

I wish it was System.Proc (for Procedure)

in Ye Olde Lingo, a procedure doesn't return something, and a function does

public void Whatever() {
  IEnumerator coroutineInstance = CoroutineMethod();
  System.Func<IEnumerator> coroutineMaker = CoroutineMethod;
  IEnumerator anotherInstance = coroutineMaker();
}

public IEnumerator CoroutineMethod() {
  ...
}

there's the distinction

[novel void]

Unity won't open/go to Vs Code when clicking console log messages or errors, but it DOES when clicking warnings only. I checked the external tools path and reinstalled Vs Code. What am I doing wrong?

[charred heart]

Sorry, it seems I lack knowledge about IEnumerator. Let me look at it for a moment. Thanks 😄

[olive lintel]

hey guys, is there an easy way to expose all of these variables in a collapsable panel in the editor for my monobehaviour? this just looks absolutely awful and is a constant headache

[summer stump]

1. Do they need to all be exposed? If some are on the same object, just make them private and use getcomponent

2. you can make a custom inspector, or use something like naughty attribute or odin serializer

[slender nymph]

there are a few ways, either using a custom editor for that class, shoving all of that into a serialized class and have a variable of that class on the MB instead, or use a 3rd party asset like Odin or Naughty Attributes that include Foldout attributes

[olive lintel]

wouldn't getcomponent be kinda inefficient espescially if I was doing it at runtime tho

[summer stump]

No

[olive lintel]

ok I think I'll try make a custom inspector then

[summer stump]

Serialized references (like drag and drop) also take time when runtime begins. GetComponent is extremely fast (especially when you know it won't fail), almost as fast as that time taken by serialized references
To worry about that as being "inefficient" is an extreme micro-optimization AT BEST, and a waste of time normally

[olive lintel]

oh ok

thank you

[swift crag]

Worry about stuff that you do many times

GetComponent in Start on something that there's only one copy of is completely fine

GetComponent in Update in something you've got 500 copies of is...less so

[lost anvil]

would a simple distance check be good enough to check whether an AI Agent has reached its destination?

only asking because ive seen people say you need to do some random complicated stuff to be accurate

[swift crag]

well, that's pretty vague

what would this "complicated stuff" be?

[lost anvil]

its probably not complicated but its this,

its not complicated now i look at it properly haha

[swift crag]

you know, this is something I've needed to figure out myself. i have really inconsistent logic for "are we there yet?" in my game

I just call it once I'm within the stopping distance

[lost anvil]

lol fair enough, thats what i was planning

[charred heart]

Ah, it finally works now. Thanks guys!

[lost anvil]

not particularly sure whats going on here hes just spazzing out everytime he finds himself a new patrol point to go to

code - https://gdl.space/xebirimeca.cs

maybe hes still in that 1 unit range of the distance check and its spamming? idk

[swift crag]

Log each time that you set a new destination

[hidden sleet]

If I have a component on a game object that implements an interface, can I use getComponent with that interface passed in to get it? Or does it have to reference the actual class name?

[swift crag]

or maybe just use Debug.DrawLine to draw a line to the destination

[swift crag]

Yep!

[hidden sleet]

Ah!

[swift crag]

Any type that the component can be assigned to will work

[hidden sleet]

that could be huge for what I'm facing right now

basically rewriting everything I've done from the ground up it's such a mess

[swift crag]

(well, except for System.Object, maybe...)

[buoyant rune]

I want to set the startgame function to this button but it aint appearing

[swift crag]

You've dragged the script asset in

You need to drag in an actual object in the scene

[buoyant rune]

wdym

[swift crag]

MonoScript is how Unity represents the actual script asset -- the .cs file

Have you added the mainmenu component to an object in your scene?

[buoyant rune]

yes to the main camera

[swift crag]

Drag the main camera object in, then

[buoyant rune]

bruh , thanks 😂

[hexed dune]

Hey I'm having some trouble with a script I wrote to slowly pan the character from any y rotation to a certain one. I set up some Debug.Log statements and the console says that it called the function without error, yet the function did not print that it executed. Any advice would be great. Thanks!

viewControls.SlowTurn();
Debug.Log("Called slow turn");

public IEnumerator SlowTurn()
    {
        Debug.Log("Slow turn executing...");
        Quaternion targetRotation = Quaternion.Euler(0, 308.55f, 0);

        Debug.Log("Target rotation: " + targetRotation);
        while (Quaternion.Angle(transform.rotation, targetRotation) > 0.01f)
        {
            float step = turnSpeed * Time.deltaTime;
            transform.rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, step);

            yield return null;
        }

        Debug.Log("Slow turn completed.");
    }```

[slender nymph]

you aren't starting the coroutine correctly, use StartCoroutine to start it, calling the method normally just makes it run to the first yield

[charred heart]

StartCoroutine(viewControls.SlowTurn())

[hexed dune]

Thank you. I will try that

[swift crag]

actually, it doesn't run at all! I thought that was the case at first

StartCoroutine does immediately call MoveNext on it

so it looks like it runs to the first yield

[hexed dune]

that worked perfectly. thank you for your help

[slender nymph]

it should run to the first yield when called as a regular method, but since nothing would call MoveNext on it then it doesn't get past that first yield. if it didn't run to the first yield then their logs wouldn't have worked at all

[swift crag]

they log "Called slow turn" after calling SlowTurn()

[slender nymph]

huh, TIL. seems it's a common misconception about how methods that return IEnumerator work, but you're absolutely right it won't actually do anything until MoveNext is called
https://dotnetfiddle.net/ZS2dYB

[rocky canyon]

you wont regret it

[swift crag]

I swear I tested this once and had the enumerator hit two yield statements in one frame (once when the method ran and once when Unity called MoveNext on its coroutines)

but, no, that wasn't the case

[tender stag]

im turning off gravity on my player

and how do i make him not be affected by other objects falling

like the y position

without freezing the y position

[tender stag]

if an object falls on his head for example

pretty much i dont want other forces of other objects acting on my player

without making it kinematic

[eternal needle]

You could try assigning to the velocity every fixed update to keep the value what you want it to be, except I believe objects will still move you slightly due to depenetration

[slender nymph]

why? this would do exactly what you want it to do, you just wouldn't be able to move it along the Y axis using physics

[cosmic dagger]

Overriding the velocity is the only other way, but that may be difficult . . .

Some irregular movement will occur if multiple objects keep hitting it . . .

[tender stag]

i spent the last 7 hours trying to figure out swimming

like just the bit of getting into it

and out

[slender nymph]

that isn't really an explanation of why you want to not freeze the Y axis

[honest vault]

whys the walking animation not playing

heres the code for the playermovement https://hastebin.com/share/ayevidebuc.csharp

[feral oar]

i feel like making it kinematic would be a good solution. any reason why you are avoiding that?

[queen adder]

This is a really simple shader question, though technically not a programming issue the other channels have not been helpful. So, this is textmeshpro appearance after changing the stencil settings to

Ref 1
Comp Greater
Pass Replace

then i added (second picture) if (c.a == 0) discard; in the pixel shader, however its pretty choppy, i think due to the anti aliasing being applied on per character basis? i dont know how to get good blending here. i've been trying for weeks but i think it's a simple solution.

[slender nymph]

you don't have a paramter called walk. remember spelling matters, including capitalization

[queen adder]

I think the problem is the stencil settings skipping any pixel which has already been set, but i think i have to have some sort of alpha threshold:(

[slender nymph]

shader questions should go in #archived-shaders

[thorn holly]

how do I check what the current scene is?

[cosmic dagger]

What have you tried? That is answered from a search . . .

[honest vault]

bro thanks it did work

[thorn holly]

oop im dumb, forgot to do that

sorry

[cosmic dagger]

Searching is always the first thing to do . . .

[honest vault]

just a question its a bit delayed when it finishes walking

even tho i have got exit time off

[cosmic dagger]

It's probably based on the animation transition settings . . .

[honest vault]

ill take a look thank you

[lusty flax]

will this have any effect on my game

[slender nymph]

you may end up with some issues where you think you are using one when you're really using the other in the code. so it's usually best to use a different name

[cosmic dagger]

No, it's a warning (yellow), stating your custom class has the same name as a Unity class . . .

[lusty flax]

will i be able to build the game with this warning

(right now I am only using my charactercontroller)

[cosmic dagger]

Only one way to find out. Give it a try . . .

A warning and an error are not the same thing . . .

[lusty flax]

because I'm getting this weird error and I don't know why (when trying to build)

[honest vault]

here i have a new player movement script is there anyway i can make it so the player move not whatever im moving with rn?

https://hastebin.com/share/wevepupivo.java

[teal viper]

This is a warning. Not an error.

[lusty flax]

yeah but it doesn't build anything

the build fails

[teal viper]

Are there actual errors when it fails?

[lusty flax]

but i dont know what these are

and before i ignored them because they did not affect the game

i fixed it

[radiant frigate]

okay so i have two enemies each one with a different movement script since i want to change it a bit, my problem is that if i write a public gameobject called player (so they know which element to move towards) on both of them it gives me an error, i´ve tried to do both of the gameobjects private but it still gives me the error

what am i missing?

okay i solutioned it

since i was literally doing copy paste for the base of the script i also replaced this so it had the same name as the other one

what a smart fella that i am (im not)

[covert sinew]

    public void MoveListEntry(List<Type> _list, Type _type, int _oldIndex, int _newIndex)
    {
        Type _listEntry = _list[_oldIndex];

        _list.RemoveAt(_oldIndex);

        _list.Insert(_newIndex, _listEntry);
    }

Will this work for what I'm trying to use it for? (Moving an entry from a list provided from one index to another)

[queen adder]

below is a regular TMP text added to the scene on a screen space canvas, above is the same exact tmp text but rendered to render texture and shown in a raw image, why so different?

why is there a saturated blue on the text in the render texture, when its supposed to be plain white

[radiant frigate]

can i use floats and ints to validate a while loop?

[summer stump]

== not =

[radiant frigate]

true

[summer stump]

And remove the float

[radiant frigate]

i wrote float cuz "patata" doesnt exist

i just was testing if i could use it

[summer stump]

Then declare it somewhere

Not inside the while condition

But yeah, of course you can use floats and ints for conditions

Same as an if statement or any conditional

[radiant frigate]

okay and this is more a math question than coding i think but i have a form of calculating the angle towards the game object that i want it to follow

and i want to make the enemy stop once it reaches x amount of distance

since im not calculating the distance but rather the angle i need to calculate the distance

but i forgot how to do that :/

[summer stump]

Vector2.Distance

This is 2d I guess, right?

[radiant frigate]

yep

so vector2.Distance and then i write this: (player.transform.position.x - transform.position.x, player.transform.position.y - transform.position.y)

[summer stump]

Or just player.transform.position - transform.position

[radiant frigate]

makes sense

distance is a 1 variable thing right?

not x and y

only the distance

as for example
distance = p
p = 15.6

[summer stump]

Distance returns a single float

[radiant frigate]

exactly what i needed

noice

ty!

[covert sinew]

I don't mean to pester, but I'm still lookinng into documentation, trying to figure out if I'm using all these bits correctly.

[native seal]

right now im creating all my data in a static class with static readonly dictionaries, is this a fine way to do it?
for example, all the tiers for each stat along with its weight, etc that can roll on an item

[native seal]

not new

Vector2.Distance is a function that returns a float

[summer stump]

Remove new- ah as umbra said

[radiant frigate]

and then i write again player.transform.position - transform.position right?

[native seal]

just remove "new"

[summer stump]

Exactly the same, without the new, as long as distance is a float

[covert sinew]

I'm not sure what I'm doing wrong here. it's asking for a List and a Type, and I tried two different ways to provide it, but it's throwing errors for both. I'm not sure what it wants here.

[wide vault]

How do I improve my code architecture

[summer stump]

typeof()

[radiant frigate]

if i write it afterwards again it works

if not it gives me an error

[native seal]

you trying to make it so you can swap between two different inventories?

Distance takes 2 params. Check the docs.

yes

[summer stump]

Oh, missed that minus sign

[covert sinew]

All I want to do is take an item in an inventory, and move it to a new location within the same inventory.

okay so then what do you think you should do?

[radiant frigate]

OH

[radiant frigate]

yeah this gives me all of it

[native seal]

then just swap the indicies?

kewk

no i just need to remove the minus sign

Why

[radiant frigate]

and then it compares the distance between transform.position and player.transform.position

if you hover over the function it tells you the parameters it needs

yep

thats why i wrote it again

Sure, that is kinda not a great one though. The bot showed 5 sites that are better

[radiant frigate]

since i just copy and pasted what i had before i had to write it again (i didnt have to i had to remove the minus) so that it has 2 Vector2

i like being able to select the language

[summer stump]

Pretty sure ALL the ones the bot listed can do that

[feral oar]

oh word? i think i just started with gdl.space and then did paste.ofcode. i must have missed it on the first one

i think i also favored the second because i could edit it after creating a link. i remember being unable (or just missing how) with the first one

[wide vault]

Isn't it easier to see all code while you on your phone with a screenshot

[feral oar]

its not the practice here even if it were

[native seal]

anyone have any suggestions? or is this fine

[feral oar]

its disruptive just sending screenies

[summer stump]

I'm on my phone. And no, not even a little lmfao
It is SOOOO much worse

Can barely read any of it

[wide vault]

👍

I'll send what bot said

[feral oar]

i love the three people reacting no that haven’t even mentioned anything

[radiant frigate]

i have no clue if its better but lets make it 4

xD

[feral oar]

i’ll make it five

[radiant frigate]

idk what i did but my game explodes whenever i start it

i think i messed up big time

kewk

[feral oar]

do it return any error messages?

[radiant frigate]

no it just freezes

whenever i enter play mode it freezes

[slender nymph]

i'd guess infinite loop

[feral oar]

i agree. i’ve only ran into that issue when i messed up a loop somewhere

[slender nymph]

yep, infinite loop because you never change the value of distance

but also why is that a loop

[radiant frigate]

oh so i have to write the formula inside the loop

[feral oar]

you need to update distance for it to stop looping. but also why have it as a loop? would an if statement not suffice?

[radiant frigate]

i guess so

[frosty hound]

Just put it in your update function, there's rarely a usecase for while loops during runtime.

[summer stump]

Make while an if
Esit: ah, lag, that was suggested

[frosty hound]

Unless you're generating something. But for gameplay logic like this, your update function is yourloop.

[feral oar]

thats a good way of explaining that

[radiant frigate]

i just learnt about while like 3 hours ago so i wanted to try but yeah totally right

an if works

[summer stump]

Any bit of code needs to finish before any other bit can. So the ENTIRE while loop needs to complete before anything can move, and if nothing can move, the while loop can never continue

[radiant frigate]

ohi wanted to paste a gif :((

[summer stump]

Please do not do that

[radiant frigate]

alrighty!

srry

[feral oar]

maybe you could try looking up when a while loop would be a good tool. then you’ll have an idea of how to experiment with it

[radiant frigate]

so whenever i use it i should make the variable that validates the loop change inside the while

[radiant frigate]

sure will do!

tyall!

[summer stump]

Basically yeah. You can use coroutines to yield the main thread too though

[radiant frigate]

yeah i have one

for instantiating enemies

[honest vault]

whys the car pink lol

[frosty hound]

Beacuse you're using a shader that isn't compatible with your chosen pipeline.

Or you're using a shader that has an error in it.

[honest vault]

how do i change that shader

[frosty hound]

Also, not a coding question.

[honest vault]

i didnt know where else to put it lol

[frosty hound]

You can ask basic Unity questions in #💻┃unity-talk , or in this particular case #🔀┃art-asset-workflow , pick one.

But you'd do well watching a basic tutorial on how materials in Unity work.

[honest vault]

done

[honest vault]

is there a yt video for that?

[frosty hound]

I can't imagine a world where something basic like that isn't covered in some video, yeah

Given that beginner tutorial series are the majority of what make up Youtube/Unity videos

[wide vault]

I feel like most of coding is functions, variables and class, if Statements and loops. I feel like I can create my entire program with these but I see people using events, lambda, return keyword, switch Statements functions and a couple of other concepts. When do you need these other concepts?

[carmine turret]

So, Im using a distance joint for my grappling hook, whats the best way to figure out what direction the player is traveling in for when I break the grapple? (2d btw)

[teal viper]

When you want a higher level of abstraction.

Which is programming all about.

[swift crag]

i mean, the return keyword is pretty fundamental...

I guess you could completely replace it with the out keyword

[teal viper]

You could write a game by just typing 1 and 0 in a text file and saving it as an exe if you really wanted, but no one does that for some reason.

[swift crag]

C# allows you to treat functions like any other object (hence delegate types)

this enables higher-order programming, where you compose functions together to get more complex behavior

[wide vault]

That's a bit extreme example

[wide vault]

Thanks

[teal viper]

Yeah, but it conveys the point: the things that you mentioned are there to help you write better projects more efficiently, not to impede your progress.

[swift crag]

by "switch statement functions" do you mean something like this?

public float GetSomething => mode switch {
  Mode.Off => 0f,
  Mode.On => 1f,
  Mode.Broken => -1f
};

because that's a switch expression

[wide vault]

When I see => it hurts my brain

[summer stump]

I mean, events are super powerful and important. They can be used all the time

[wide vault]

Yes

[swift crag]

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

[slender nymph]

in this case, it's just expression body syntax and isn't really anything super complicated

[swift crag]

public float Constant => 1f;

a get-only property that returns 1

[swift crag]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/lambda-operator#expression-body-definition in particular

oh, huh, that's new...

[wide vault]

If you look at most beginner stuff. You never see that

[slender nymph]

only the low quality beginner stuff

[summer stump]

Most beginner stuff is written poorly 🤷‍♂️
Writing like that makes things tough when you want more complex systems

[swift crag]

it's a nice way to write methods and properties that fit into a single expresison

public override bool CanEnterState => base.CanEnterState && CanEnterWithTarget(candidateTarget);

public override bool CanEnterState => base.CanEnterState && Vector3.Distance(interactor.InteractPoint.position, interactable.TargetTransform.position) <= range;

on the ragged edge of "line too long"

[wide vault]

Jumping from that beginner level to more advanced I find difficult

i cant 😦

[bitter bramble]

make a top down view game where you are a shark and you have to eat people to gain points

[radiant frigate]

good starter idea imo

[covert sinew]

https://pastebin.com/kDgNhNZv

Here's what I've finally come up with, after working on it for a long while. Thoughts on this?

My inventory system doesn't have set slots, but creates and destroys them as needed, so it needed something more complex than what you provided.

[queen adder]

where is the navigation tab in unity so i can bake like the walkable areas?

[teal viper]

You can add it via the windows menu. If you're on a recent version, it moved to the navmesh surface component though

[small mantle]

Why can't you just add a variable? This doesn't work: cs void Update() { cooldownClock + Time.deltaTime; }
But this works? cs void Update() { cooldownClock = cooldownClock + Time.deltaTime; }
Can someone explain why this is the case, please?

[summer stump]

What happens to the result of just adding it?

[small mantle]

Are you talking about this situation? cs void Update() { cooldownClock + Time.deltaTime; }

[summer stump]

Yes

[small mantle]

It gives an error.

[summer stump]

I know

[covert sinew]

Also, if anyone has the time, It'd be helpful if someone with experience could review this, and tell me if my code here is adequate or psychotic, I'd be in your eternal debt.

(18 to 327 are the areas in question where I worked on today)

[summer stump]

I am asking what SHOULD happen in that case

[small mantle]

The variable will have Time.deltaTime added to it.

[summer stump]

Then use +=

But just adding them, the compiler wouldn't know what to set the result to.
Assignments use =

Think it through, and that will explain why you can't

void Update() {
        cooldownClock += Time.deltaTime;
    }

[small mantle]

Can you explain the differences between += and =+? I think this is what I am not getting

[summer stump]

One is valid code and the other is not?

[small mantle]

Both work, but are they different?

[summer stump]

Oh suprising. Well, then no, I would assume they are not different

I thought =+ was a syntax error. Interesting

All I was saying is that THIS makes no sense, because there is no = sign

void Update() {
        cooldownClock + Time.deltaTime;
    }

So the parser isn't trying to assign something

[small mantle]

Okay, thank you for the help!

[summer stump]

You COULD make a language that does it, or perhaps overload the + operator, but it is just not default in c#
That is just an arbtrary choice by microsoft

[radiant frigate]

the way of calling another script was creating a public class inside the script i wanted to call the other with right?

[summer stump]

Not sure what you mean

[radiant frigate]

lemme try to show it

[summer stump]

You do NOT need to have the classes in the same file to call them

In fact, they should NOT be in the same file

[faint osprey]

Im making the camera shake on my virtual camera when the player moves right or left for a bit with this coroutine ```private IEnumerator CameraShake(string direction)
{
if(direction == "Right")
{
while(true)
{
Debug.Log("woking");
VC.m_Lens.Dutch += 1;
yield return new WaitForSeconds(0.01f);

            if(VC.m_Lens.Dutch == 10)
            {
                break;
            }
        }

        while(true)
        {
            VC.m_Lens.Dutch -= 1;
            yield return new WaitForSeconds(0.01f);

            if (VC.m_Lens.Dutch == 0)
            {
                break;
            }
        }
    }

    if(direction == "Left")
    {
        while (true)
        {
            VC.m_Lens.Dutch -= 1;
            yield return new WaitForSeconds(0.01f);

            if (VC.m_Lens.Dutch == -10)
            {
                break;
            }
        }

        while (true)
        {
            VC.m_Lens.Dutch += 1;
            yield return new WaitForSeconds(0.01f);

            if (VC.m_Lens.Dutch == 0)
            {
                break;
            }
        }
    }
}```

the problem is because its a coroutine if i move right or left too quickly the while loops dont run properly because the "dutch value" is reaching the set point for it to break. how would i go about fixing this

[radiant frigate]

okay wait lemme reword it

[covert sinew]

@teal viper

In the code, I actually explain what everything in it does in excruciating detail through comments.

[radiant frigate]

how can i call a function inside script b while im inside script a

[covert sinew]

It's my personal preference to overexplain my code in comments, since I have a habit of forgetting how programming works, and how I did things, and what the hell my code is doing.

[teal viper]

I don't need excruciating details. Just an overview to know what I'm gonna read about.

[summer stump]

public MyClassName scriptA

scriptA.MyFunction()

[radiant frigate]

my brother is just another me fr

[summer stump]

https://unity.huh.how/references

[radiant frigate]

ty ill check that out

[covert sinew]

It's an Inventory System which uses Lists of Inventory Objects, spawning and deleting inventory slots as needed to hold everything in it, rather than having discrete slots

Today, I completed the following functions:

Add Items
Add Items to Specific Slots
Remove Items (of type)
Remove Items from specific Slots (of optional required type)
Move Items (the most complex piece, which can handle stack splitting and merging and all that jazz)

[teal viper]

Waiting for a specific value like .01 is probably not gonna work well, depending on the framerate, there might be +-0.01 difference or even more.

[teal viper]

Okay. Sharing the code would also be useful.

[faint osprey]

but im using that wait for seconds to make my while loop go slower so it looks smoother in the transition for the camera shake

[covert sinew]

I did

It's up above there.

[teal viper]

Ah, you shared it previously. Didn't notice.

[teal viper]

I'd suggest waiting for the next frame and then do logic according to the time passed.

[faint osprey]

I dont know how that would fix it tho because if the player is pressing move faster than the camera is completing its shake cycle it will just break every time

[teal viper]

It looks fine aside from maybe I wouldn't make it an SO. Also, what you call an override is actually an overload. Method override is when you override a method from a base class.

[covert sinew]

I mostly made it a Scriptable Object so I can easily use a unity plugin that allows me to save scriptable objects without converting to structs, since I'm going to need massively complex save files, and I would get lost in the weeds if I had to manually set all of that up myself, and also so I can have multiple inventories easily and handle them all.

[native seal]

whats the purpose of doing it this way?

also SO's work well for an inventory, im doing the same thing

[covert sinew]

I have a scrolling inventory, so it can't have finite slots, and I think it looks sexy to have items "loose" in your inventory.

[teal viper]

You can save plain classes as easily. You don't need structs.
And you can have as many inventories as you want. I don't see how SO is helping with that.

[native seal]

so an infinite inventory?

you still need to define specific slots, I don't understand how that works out

[teal viper]

Might be helpful if you provide a video showing the issue, as it's not entirely clear what it is.

[covert sinew]

It's been over a year since I last worked on my save and load system, but it nearly broke me, man. Saving and loading an inventory, from everything I researched on the matter, was a terrifying tarpit of insanely complex data structures, that had to be convverted to and from one another in ways I simply am not a good enough coder to understand.

Using SO's is absolutely easier than trying to save and load Classes directly. Like, I'd say at least 50% easier.

[covert sinew]

A save and load inventory system is what very nearly made me quit game development, and was so frustrating that upon finishing it, I had a 9 month hiatus, just in sheer catharsis.

[teal viper]

Using an SO changes absolutely nothing about how it's saved. You're still limited to serializable data.

[covert sinew]

It's easier to add items to it, since Lists are more friendly than arrays.

[covert sinew]

I have a plugin that makes SO's serializable, is the thing.

I just directly serialize/deserialize the SO

[teal viper]

They are serializable by default though

[covert sinew]

No they aren't.

[teal viper]

You don't need a plugin for it.

Yes they are

[native seal]

dlich hes talking about directly saving the SO to json

it wont work

[teal viper]

If they weren't, you wouldn't be able to create instances of it in the editor.

[covert sinew]

Last time I worked on it, SO's were explicitlly not fully compatable with saving to JSON, yeah

[native seal]

I believe im making a game very similar to him and have solved this issue myself

[teal viper]

They are.

[native seal]

the only reason I use SO's for inventories is to be able to easily plug it in to anything

instead of holding a reference singleton or whatever

[covert sinew]

When did this change?

[teal viper]

Never.

You probably misunderstood something about serialization.

[native seal]

dlich you are misunderstanding him i believe, you cannot directly serialize an SO to Json

[covert sinew]

nine months ago, I had to install a specific plugin to Serialize SO to JsON

[native seal]

you would have to serialize the data in it and then rebuild it

[covert sinew]

They were NOT serializable to JSON.

[teal viper]

Of course you can.

[radiant frigate]

what does an instance of an object mean?

[native seal]

i've tried, you can't

[covert sinew]

Not without a plugin, last time I was working on gamedev.

[native seal]

thats why I made my own save system

[covert sinew]

Yeah. I took the other angle, and just used a plugin that MAKES them serializable to json

[teal viper]

@covert sinew you two should check JsonUtility documentation. It plainly states that SOs can be serialized

[strong moth]

Is this an excessive amount of assembly definintions or nah

[teal viper]

It means that your reference doesn't point to anything. Do you understand the concept of objects and instances in C#?

[teal viper]

Not unless there is a problem with it?

[strong moth]

no problems

but some of these asmdefs are for a single script

[teal viper]

It does sounds unnecessary and clunky, but nothing beyond that.

[native seal]

this is what happens when I try to serialize an SO using JsonConvert

nothing was saved

[radiant frigate]

i think i am refering to something

or am i doing it the other way

[teal viper]

What's JsonConvert?

[radiant frigate]

and i should reference from the other script around?

[native seal]

the newtonsoft json utility

[teal viper]

You should use JsonUtility which is the native unity way to convert an object to a json.

[teal viper]

You should first find out what throws the error. For that you need to read it.

[radiant frigate]

the line 40 (the first image)

[teal viper]

What line throws?

[native seal]

doesn't work, also newtonsoft is now built into unity

[teal viper]

Okay, what are the references on that line?

[native seal]

https://github.com/applejag/Newtonsoft.Json-for-Unity it is this btw

[teal viper]

It does lol

[rich adder]

this isn't even the unity one is it

[radiant frigate]

thats all it does

[native seal]

its in unity's package manager

[radiant frigate]

i want to check if the bool shooting in the other script is false or true

[teal viper]

That doesn't answer my question. What are the reference type object on that line?

[rich adder]

yes ik

why are you serializing the SO anyway ?

[radiant frigate]

srry im not english native so i dont know exactly what you mean by reference type

[teal viper]

Please read the documentation that I mentioned.

[rich adder]

generally they are not meant for mutable data so not sure why you'd serialize that instead of a mutable poco on the SO itself @native seal

[teal viper]

Google C# reference types vs value types. And come back when you can answer my question

[radiant frigate]

alright

[cosmic dagger]

If it works for you, it's fine. Just make sure the asmdefs have the correct assembly references . . .

[native seal]

that's what I do

the reason I use an SO for the inventory is just ease of use

being able to plug it into anything

[rich adder]

Imo You should not be using it for mutable data

[native seal]

it works very well

ive heard that many times and I don't really see why it matters

[teal viper]

You usually want to be able to create new inventories at runtime and pass them around. Having them as SO brings a lot of garbage that you don't need with it.

[glossy compass]

does anyone have a good free tutorial series or course on learning C# for unity?

[rich adder]

!learn

[eternal falcon]

:teacher: Unity Learn ↗

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

[glossy compass]

yeah but that focuses on overall? is there one that focuses primarly on just programming?

[native seal]

yes I agree that would be the one limitation

[radiant frigate]

a value type is stored in a stack* while a reference type stores the direction of other stack?

[rich adder]

heap vs stack

[cosmic dagger]

Did you look on the site for the programming tutorials?

[glossy compass]

oh does it have some?

[rich adder]

yes the c# one pinned in this channel

[radiant frigate]

okay so now i should look what a heap is

[teal viper]

The second part of that sentence doesn't make sense. You don't have to understand about the stack and the heap for now. Just learn what types are reference types and what value types and how to differentiate them.

[glossy compass]

ah okay sorry thanks

[cosmic dagger]

Yes, that's why they sent you the link. Click on it and search for the tutorials you want . . .

[glossy compass]

ok cool thanks

[radiant frigate]

basically what i understood is that whatever is a int, bool, float etc is a value type and class string arrays are reference

so answering your question im not doing any reference

right?

and thats the problem

[teal viper]

Then you wouldn't get the error.
Go through all the identifiers(variables) on that line write down their types.

[radiant frigate]

identifiers ?

ohh

its just a bool

[teal viper]

Names of variables

[radiant frigate]

and its value type

[teal viper]

No. It's not just a bool

Look again.

[rich adder]

value types cannot be null by default

[cosmic dagger]

Also, a value type in not stored on a stack. That's a misleading conception . . .

[teal viper]

Break down all the keywords and write down what they are.

[radiant frigate]

im also refering to the class multiShootEnemyShooting

[cosmic dagger]

Bingo . . .

[radiant frigate]

and a class is a reference type?

[native seal]

c# generally abstracts all the stack/heap stuff

[teal viper]

Yes

[radiant frigate]

it was what the guy in the video explained

okay let me read the error now

[teal viper]

It's a reference to an object.

[radiant frigate]

object reference not set to an instance of an object

im kinda clueless now

[rich adder]

you don't have an instance in your declared variabe

[teal viper]

Do you know what a null is?

[radiant frigate]

nope

[rich adder]

so you cannot use something thats missing/doesnt exist

[teal viper]

Do you know what a reference is?

[native seal]

imagine your program recieving a blank blueprint with nothing built yet

making an instance of an object "builds" that blueprint

a class definition is just a blueprint

[radiant frigate]

the name of the variables?

[teal viper]

No. Did you learn anything about object oriented programming yet?

[radiant frigate]

nope

[teal viper]

Well, then you probably should go over it first. It's crucial to understand to be able to work with C# and many other languages.

[radiant frigate]

i know so little (type of variables, how to mess a bit with objects components, loops, switch and i think if counts as a loop but basically thats all)

[native seal]

digital post your full code in gdl.space

[radiant frigate]

omw

[rich adder]

you need to expand on your fundamentals

[teal viper]

I'd recommend learning the mentioned things before proceeding.

[teal viper]

Spoon-feeding them isn't a great idea.

[radiant frigate]

https://gdl.space/ujenabuqus.cpp

[native seal]

why? it's one way to learn

[radiant frigate]

thats what im going for

[native seal]

then they can reference the solution and figure out what went wrong

[teal viper]

It's one way to learn one specific thing and have a broken understanding of the whole thing.

[radiant frigate]

b4 yesterday i had no clue how to use loops or switchs

[rich adder]

the microsoft docs has everything you need

[native seal]

digital do you understand the concept of classes

also im not "spoon-feeding" the answer, I want to see what was going wrong

[radiant frigate]

a class is like the script?

[native seal]

class in a general sense

a script can have multiple classes in it

[rich adder]

here
https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/types/

[cosmic dagger]

A class is a Type . . .

[radiant frigate]

a reference type ?

[teal viper]

It happens to be a reference type, yes.

[native seal]

for example, a Vector3 is a type

[rich adder]

its all explained in the link I've sent

[native seal]

i doubt he's going to understand that if he doesn't understand basic loops

[radiant frigate]

i dont know how to read all that

[rich adder]

its all very much in english words.

[cosmic dagger]

Value types are only stored on the stack when declared as a local variable or a method parameter . . .

[radiant frigate]

i understand that i can somewhat ignore all the system. and whatever remains takes part of either reference/value type

[radiant frigate]

i dont know what a stack is ( i have the thought that it is like a place where it holds information about something)

[rich adder]

dont worry about that now

[native seal]

imagine that value types typically hold very basic data (including primitive types such as character, int, etc), reference types typically hold more complex data such as your class

[cosmic dagger]

Somewhat. You can worry about that later . . .

[rich adder]

Ehh You could say Quaternion is quite Complex and is a struct

[native seal]

"typically"

but yes

[radiant frigate]

i saw a video and i understood something like (numbers and bool is value type) and (fancy things with strange words are reference (arrays, class, strings))

[karmic escarp]

is there a way to reference objects without having them be included as a reference in a script or be part of a trigger? trying to put together a sort of tile lighting system

[native seal]

in c#, when you pass a "value" type into a function, anything done to it will not change the variable outside the scope of that function, this is not true for reference types since you are passing the same "pointer" that points to the reference type

[cosmic dagger]

That's a "special" case . . .

[rich adder]

tile lighting ?

[rich adder]

in fancy Unity fashion

[karmic escarp]

pretty much something like this https://static.wikia.nocookie.net/baldis-basics-in-education-and-learning/images/8/85/Custom_lighting_teaser.gif

[radiant frigate]

okay give me like 5 minutes to understand this because it has a lot of words that arent popular in my mind

[rich adder]

why would you not store the references ?

[radiant frigate]

what do you mean with passing a value type into a function? using a value type inside a function?

[karmic escarp]

i was thinking about making a tile lighting object that would affect objects around it in a certain range as opposed to giving each individual tile the same script

[native seal]

to simplify it, just remember that when you pass a value type, you are copying it into the function and the function has no knowledge about it outside of that function. A reference is like giving the function an "address" of your type that it can go to and modify

[rich adder]

just put the tiles in a List/Array. then iterate through them

[native seal]

like myFunction(int num), the parameter num which is an int is passed into the function

[teal viper]

They still don't understand the concept of types and instances I think. They won't be able to understand that explanation.

[cosmic dagger]

You must have a reference to the objects in order to act on them. Assign the references on the current script, a different script, or find/search for them during runtime (slow) . . .

[native seal]

compared to myFunction(myClass class)

the "address" of your class is passed into the function

the function can then go and modify it directly

while an int, a value type, is just copied over

[radiant frigate]

but i dont want to modify something from outside the function i just want to check if the bool is true or not

maybe im mixing things up

[native seal]

im explaining the general difference between value types and reference types

[radiant frigate]

yeah true

kewk

[native seal]

when your program asks for "multiShotEnemyShooting.shooting" it looks for the address and cant find anything

[cosmic dagger]

You're going off-topic about what they need to learn/figure out. The goal was understanding a reference type so they can find the reference variable to understand a null reference error . . .

[teal viper]

You want to access the bool that is on some specific object. To be able to do that, you need a reference to that object. You can't access something in something that doesn't exist.

[native seal]

im explaining the fundamental difference between value types and reference types

[radiant frigate]

so i need to create a var gameobject with the item that holds the script inside on it?

[native seal]

a value type can never have a null refereence because the value is the thing itself

not a pointer to something

since your script is a monobehavior, you need to populate "public MultiShotEnemyShootingScript multiShotEnemyShooting;" on your gameobject

[teal viper]

No. You already have a reference, but it's not pointing to anything.

[radiant frigate]

populate?

[teal viper]

I'd suggest googling Object oriented programming and understand that concept first.

[native seal]

when you declare public MultiShotEnemyShootingScript multiShotEnemyShooting at the top of your script, you are promising to give it a built "object" that follows the blueprint of your type MultiShotEnemyShootingScript

[cosmic dagger]

You have a reference variable but it is not assigned a value . . .

[native seal]

if you don't fulfill that promise, you will get that error

either drag that script into that slot in the inspector, or get the component in void Start

by using GetComponent

assuming your other script is also a monobehavior

[radiant frigate]

oh so i need to write GetComponent(and then localize the script)?

[native seal]

what do you mean localize?

[radiant frigate]

lemme show you (my keyboard doenst have the > and the other way around symbols so i cant write the exact thing here)

rb2dEnemy = GetComponent<Rigidbody2D>();

smth like this

[native seal]

yes

[radiant frigate]

but instead of rigidbody

script

[native seal]

yes, assuming your script is a monobehavior that is also on the same gameobject

[radiant frigate]

yep

[native seal]

you did the same thing when getting the player

player = GameObject.FindGameObjectWithTag("Player");

it also gets a reference to the player gameobject

[radiant frigate]

if it werent i would have to create a gameobject , and then search inside the gameobject components for the script?

[native seal]

no, not necessarily, it depends on how you made your class

[radiant frigate]

more than create a gameobject creating a variable that is a gameobject

[native seal]

and what functions it serves

[radiant frigate]

what is the difference between monobehaviour and whatever else types there are?

[native seal]

monobehavior is a class that unity has made that your class can inherit from

research more into object oriented programming to understand inheritance

[teal viper]

If you answer the next question, you would be able to solve your issue easily:
What is multiShotEnemyShooting and does it exist on line 40?

[native seal]

in simple terms, inheriting monohevaior allows you to place the script onto a gameobject and use the premade functions Start and Update

[radiant frigate]

multiShotEnemyShooting should be the script that i need and it doesnt exist since i didnt reference it (either by GetComponent or dragging it around)

i think

[teal viper]

That's correct. So do you understand how to solve it now?

[radiant frigate]

yep

i could have done it earlier

[teal viper]

Check the tutorial again and see where they assign it.

[radiant frigate]

i just forgot completely

kewk

[native seal]

if multiShotEnemyShooting wasn't a monobehavior, you would create a new one by using the "new" keyword

[radiant frigate]

what tutorial?

[radiant frigate]

okay

[teal viper]

Was it not a tutorial code?

[radiant frigate]

nope im writting on my own

[native seal]

however, your class needs a constructor so that the program knows how to fill in the variables in your class

if you were to use "new"

[radiant frigate]

messing with things here and there and trying to get problems so i can learn

[rich adder]

make a game inside C# console application, You'll be a c# chad in no time

[radiant frigate]

not the best way of learning but each day i assign myself something new to learn and to try and give an use to it

[teal viper]

Ok well, I really suggest you go and learn the basics, starting with OOP. Because you're risking being ignored by people here in the future. At least by people that support proper learning methods.

[native seal]

appreciate it

[radiant frigate]

OOP?

[radiant frigate]

KEWK

[native seal]

i dont believe telling a beginner read the documentation is the best solution

[teal viper]

Object oriented programming. Something I mentioned numerous times in the last hour

[rich adder]

learning how to read documentation should be one of the first things to learn as beginner..

[native seal]

yes, but when he doesn't understand loops, i don't think it would help

[teal viper]

It depends. There are appropriate materials. If you don't understand OOP, it's too early to read the documentation too.

[rich adder]

who carees about loops, they barely know what an object is

[radiant frigate]

docs are straight up confusing since sometimes you get no context of things and use fancy words that with my current level i cant understand

[native seal]

sure

[rich adder]

lookup words you don't understand

[native seal]

be VERY warey of unity tutorials please

[rich adder]

the docs has a list of all the keywords used in c#

[radiant frigate]

its not just the words

[radiant frigate]

what is warey?

[native seal]

cautious

[radiant frigate]

i dont watch them

[cosmic dagger]

Where did anyone say to read the documentation? They mentioned learning c# basics as that is necessary to start with the Unity basics of programming . . .

[radiant frigate]

i watch tutorials of c#

[native seal]

someone else linked the documentation

[rich adder]

The microsoft site isn't just "docs"

[radiant frigate]

its like the docs but explained by someone

[rich adder]

they are learning lessons

[native seal]

ah i see, my bad

i didnt realize what you linked

[rich adder]

this

it explains everything

[native seal]

yes very good

[rich adder]

they have videos too

[radiant frigate]

its in spanish but basically this is what i watch https://youtu.be/BFJU--8yqT8?si=JLUxPAf19eCt4-ub

those types of videos

i dont like unity tutorials

since they just give you the solution and usually dont explain anything at all

[rich adder]

learning c# through unity is more diffcult

[native seal]

that isn't even the problem

unity tutorials give very bad architecture advice, such as making every field public

i recommend not doing that

a field should default to private and only be public if theres a very specific reason for it to be public

[radiant frigate]

i tend to write public if i want it to be changeable from other places or private if i only want to mess up with it from inside the script

[cosmic dagger]

Oh, you meant the c# docs, not the Unity one. That's different. They provide definitions and (sometimes) examples of the term in use. They have to figure out what it means from somewhere . . .

[native seal]

yes i realized that like i said

[native seal]

it is generally better to make it private and only allow changes through a public function

since you will be able to put restrictions on it and whatever other logic you want associated with changing that variable

[radiant frigate]

so making everything private and whenever i want to change a variable make a public function that manipulates it specifically?

[native seal]

yes

if your class is a monobehavior, you can add [SerializeField] before your variable to allow it to still be changed in the inspector

it is very useful

[radiant frigate]

yeah i have that on all

even tho they are public

[native seal]

they should be [SerializeField] private instead

[radiant frigate]

i usually write public and once i know i dont want to use them in other place change it to private

[native seal]

do it the other way around

private and only public for a specific reason

[radiant frigate]

always private unless i want it to be public

aight

[native seal]

90% of my variables are private

[radiant frigate]

that will take out possible problems from the equation right?

[cosmic dagger]

This is what most beginners do until you learn about properties, methods, and encapsulation. You'll begin to use the correct access modifier and decide whether a field should be a property or variable . . .

[native seal]

yes ^

if your project is small you wont have many problems

[radiant frigate]

i had a deja vu of this

[native seal]

but when you scale things, you will have problems

[radiant frigate]

havent you told me this b4?

[native seal]

if 20 things are changing your public variable

[radiant frigate]

yeah instead of 20 things changing a variable its better to have 20 things call a function that changes that variable

didnt think about it but it makes sense

[native seal]

yes, since you can add whatever other logic in that function to restrict those other 20 things trying to change it

for example, not allowing it to go below 0

or something like that

[radiant frigate]

yeah

the same thing happend 3 days ago

i spend like 2 hours trying to understand something that i already knew

but since im a dumb ahh i forgot smth and just messed up

[native seal]

we all start somewhere

[radiant frigate]

this should be it right?

[native seal]

yes, make sure that class is added as a component on your gameobject

[radiant frigate]

it is

[native seal]

similar to rigidbody, which is just another class that unity has already made

[radiant frigate]

i thought that was the issue b4

because i forgot to add it

[rich adder]

yu should always opt in for a serialized field and drag n drop reference inside inspector instead

[radiant frigate]

but i added it and it kept displaying so i came here asking if someone knew what was happening

[native seal]

either one is fine really, but since unity gives you the ability to drag and drop it cleans up code

[radiant frigate]

i dont like that method since instantiating prefabs usually doesnt let you do that

[native seal]

prefabs are completely different

[radiant frigate]

yep they are

[native seal]

nothing to do with that

[rich adder]

Well you have GetComponent its better to do it since the components are already on the object

and yes Prefabs cannot reference scene objects

[radiant frigate]

yep

had that problem with the "bullets"

since they were a prefab

[rich adder]

Why do your buellts have a reference to scene objects..

thats poor design

[radiant frigate]

the enemies*

[rich adder]

why ?

[radiant frigate]

for following the player

[native seal]

for prefabs you generally get the references at start

[static cedar]

Real.

[native seal]

if its a gameobject in your scene

[rich adder]

no for prefabs you pass the dependency via whoever instantiates it

[native seal]

that works too

[radiant frigate]

i have this written in the enemy prefab

[rich adder]

Everytime you spawn an enemy you're doing a Find

instead of getting the same reference from the thing that spawns it

[radiant frigate]

hmmm i get what you are saying but idk how to execute that

[cosmic dagger]

Having [SerializeField] on a public variable is redundant. [SerializeField] allows a private field to appear in the inspector. If your field is public, by default, it'll appear from the inspector . . .

[radiant frigate]

didnt know you could do that

[radiant frigate]

yes i know but once im finished coding i replace everything with private

so im just left with the fields and messing around to find the number i want

[cosmic dagger]

Yep . . .

[rich adder]

the object in the scene that spawns holds the reference to say the player, then once its stored on awake once every time you Instantiate you can pass player via a Method like "Init()" inside enemy that gets that reference

this has good example
https://unity.huh.how/references/prefabs-referencing-components

[radiant frigate]

i didnt understand that i will check for some explanation in some c# video tho

[radiant frigate]

oh

i guess i wont be needing a video

[rich adder]

passing objects/data through methods should be one of the first basic concepts you should learn

you'll probably be doing it A LOT

[radiant frigate]

yeah not just probably but nearly 90 % of my scripts have the walmart version of that

kewk

[rich adder]

it looks intimidating at first but it gets simpler with time , just keep doing it and eventually "it sticks"

[radiant frigate]

sure will

[cosmic dagger]

At least upgrade to the Target version . . .

[radiant frigate]

how is that?

XD

no need to explain

i will learn it myself

but first i wanna finish with the new type of enemy

[rich adder]

you know they meant Target the store not an actual method or function lol

[radiant frigate]

AINT NO WAY

BHAHHAAHHAHAHAAHAHAH

srry im from spain

we dont have target nor walmart

[rich adder]

You guys have walmart but not target?

oh

[radiant frigate]

nope but walmart is famous asf

and also a lot of memes happen inside there

[rich adder]

amazing lol

[radiant frigate]

omg im dumb

BHHAHAHAHAHAHA

target version

makes complete sense

since my problem has to do with targetting a gameobject i got confused asf

KEWK

this made my day

anyway imma go eat havent eaten in like 30 hours or so

ty for the help!

[cosmic dagger]

Oh, I figured you knew about Target since you mentioned Walmart . . . 😄 🤣

[radiant frigate]

i know about target but my mind just ignored it 🤣

[timid badger]

Hello! I'm remaking breakout in unity and I needed to save my highscore so when I restart the game, it saves the highscore. With what I have currently, the score and highscore count up at the same rate but I'm not really able to get it to save.

this is what I have and I know it's wrong but I'm not quite sure how to make it work either because I've tried all kinds of youtube tutorials

but my score is counting up in another script which is throwing me off

[teal viper]

Pay close attention to the strings that you're using.

It would be better to assign the string in the field initializer or serialized field and use that variable everywhere else.

In order to avoid human errors.

[timid badger]

Yeah.. what I'm doing is for an assignment and my teacher isn't expecting a serialized field. I just wanted for the highscore to save when I exit playmode. I reset my scorecount when i run out of lives so that I do manage to keep my highscore when I restart in the same play session

I just don't quite understand how I can save my highscore using the playerPrefs because that is what I saw in a lot of youtube vids about how to save highscores

[teal viper]

Again, pay attention to the string that you use in start and in update.

And my suggestion is:

private string highscoreKey = "HighScore";
//When using player prefs:
PlayerPrefs.GetInt(highscoreKey);

[teal viper]

What string are you using when getting and setting the value in player prefs? Is it the same string..?

[timid badger]

it probably was, i just removed the strings and it works the same as it did before. i think i was referencing from another project but I ended up changing my values to static ints so that means I don't need the strings right?

[teal viper]

What? No. I think you're misunderstanding

Share the script properly, so that I can copy paste it.

[timid badger]

oh crap sorry! give me a sec.. thx for helping me

[teal viper]

Nevermind, I did myself.

Does the string parameter here:

PlayerPrefs.HasKey("HighScore")

Equal to the string parameter here?

PlayerPrefs.SetInt("Highscore", highScoreCount);
```@timid badger

[radiant sail]

anybody know how i can get similar gun interpolation to this when looking around
ive searched up what type of easing it is (Elastic out ease)
but i cant figure out how to implement it into my code and everthing i try dosent work so i end up just resetting it back to this

public GameObject gunPos;
public Vector3 TargetRot;
TargetRot.x = Mathf.Lerp(TargetRot.x, gunPos.transform.localRotation.x -Input.GetAxis("Mouse Y"), 5 * Time.deltaTime);
TargetRot.y = Mathf.Lerp(TargetRot.y, gunPos.transform.localRotation.y + Input.GetAxis("Mouse X"), 5 * Time.deltaTime);
gunPos.transform.localRotation = Quaternion.Euler(TargetRot);```

i remember in my old game i accidentaly recreated it by like doubling the rotation on a second object but i dont remember how i did it

[timid badger]

I am not quite sure how to check that but I'm guessing it doesn't or else the high score count would actually be holding that value after i start another play session. Sorry, I'm trying to figure that out but I'm still very new to unity and coding just in general

[desert flume]

I wanna spawn a prefab in a random place (ive alr done that)

but i want to make it so if the random place is already occupied by a certain object with a certain tag

then it would choose another random place

how would I get a BoxCollider2D for the random place

[timid badger]

oh they are equal to each other i think that is the problem, i went back to the video I was using and I think i'm seeing what to do

[desert flume]

i mean, it really isnt possible since that place is a coordinate

not an area

overlap point nvm

[keen dew]

You can check it by looking with your eyes

Do you see any difference between "HighScore" and "Highscore"?

[timid badger]

there's a difference now but it's still not saving my score

[keen dew]

wtf

[timid badger]

   public void Start()
   {
       if (PlayerPrefs.HasKey("HighScore"))
       {
          
           highScoreCount = PlayerPrefs.GetInt("HiScore");
       }
   }

[keen dew]

No, the problem is that they're different. They must be the same obviously.

[ivory bobcat]

I only see Get and not SetInt https://docs.unity3d.com/ScriptReference/PlayerPrefs.SetInt.html

[timid badger]

in my first block of code they are the same

[keen dew]

Yes, but not when you save the value

[gaunt ice]

consider using private static readonly string as your key not some string hardcoded into

[timid badger]

this comment is the one that helped me

love you all

i can sleep tonight now

[teal viper]

They are not the same. One had capital S in score, the other had lower case s.
Just in case it is not obvious yet: S and s are 2 completely different characters and are not equal to each other, thus HighScore is not equal to Highscore

[timid badger]

yeah true my eyes are failing me, thank you for the help though

[teal viper]

That's why you should save the string in a variable and use it everywhere instead of typing it manually.

[radiant frigate]

i cant convert a Vector3 into a quaternion, how can i make it rotate ? here is my aproach and it didnt work

[eternal needle]

by using quaternion.euler to convert it, but your initial vector is wrong from the start. you are using quaternion values, these are not what u think they are. use the eulerAngles

[radiant frigate]

what is an eulerAngles?

nvm imma check a video explaining it since it seems a dense topic

[radiant frigate]

im not learning allat

xD

i´ve seen 3 videos of euler angles and one on quaternions and i dont understand a thing

[teal viper]

You don't need to learn quaternions. You just need to know that they're different and shouldn't be messed with manually.

[radiant frigate]

oh the guy said later that normally all that is made with a computer

[visual hedge]

Okay onay

Not sure what was wrong with that though

[timber tide]

usually you can just use lookat with projectiles because you're probably aiming at some target anyway

[radiant frigate]

nope im making it spread in a clocksystem

each "2 hours direction " i want to shoot a bullet

[teal viper]

Depends on what you tried to do. It could've been correct if you tried to rotate on the z axis.

[radiant frigate]

i just want to rotate the z axis

[timber tide]

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

try that one

[radiant frigate]

but i want to rotate the z axis

[timber tide]

https://docs.unity3d.com/Manual/QuaternionAndEulerRotationsInUnity.html
Also worth reading

[teal viper]

"Rotate z axis" doesn't make any sense.

[radiant frigate]

yeah srry

[teal viper]

What are you trying to do actually?

[radiant frigate]

i want to rotate him based on the z axis

[teal viper]

We say "rotate around a x/y/z" axis"

[timber tide]

AngleAxis rotates it around the axis you provide it so experiment with it

[teal viper]

Imagine an axis as a line going through your object. You rotate it around that line

[radiant frigate]

yes i know that

thats why i want to rotate around the z axis

[teal viper]

Now the question is, is it the local z or the world z?

[radiant frigate]

so each bullet has his own direction

world z

oh no

the local z

[teal viper]

There's a Transform.RotateAround method that can rotate the object around any point/axis.

[radiant frigate]

im going to investigate about that then

ty!

[radiant frigate]

srry for the ping but in my case i dont care that a gimbal lock may occur right?

since the only axis that im using is the z

[visual hedge]

I think I did? Not like 'rotate', but assign an euler angle to z

[radiant frigate]

it says i cant use "eulerAngles" for that

then i get the problem i had at the start

that was my first approach

but it tells me that i cant transform a vector3 into a quaternion

[visual hedge]

Should the bullet rotate or just spawn at desired angle?

[radiant frigate]

spawn at a desired angle

[teal viper]

Right.

[visual hedge]

Then what's the problem with (bullet, transform.position, Quaternion.Euler(0, 0, zRotation); ?

[teal viper]

That's totally not what I mentioned

[teal viper]

Yeah, in this context it could be correct.

[radiant frigate]

that it wont let me use it

it gives me an error but its traduced poorly to spanish

Non-invocable member 'name' cannot be used like a method.

[visual hedge]

Is zRotation variable a float?

[radiant frigate]

yep

[teal viper]

It should be fine. We didn't know the desired rotation axis back then. At least I didn't see any mentions.

[radiant frigate]

yeah but i checked the doc and it says that i can use eulerAngles too

[visual hedge]

Euler needs some using unity.System; ?

[radiant frigate]

i dont think so

[teal viper]

What exactly did it say?

[visual hedge]

Can you please show the code abd the error?

[teal viper]

No. Euler is not even a type.

[radiant frigate]

https://learn.microsoft.com/en-us/dotnet/csharp/misc/cs1955?f1url=%3FappId%3Droslyn%26k%3Dk(CS1955)

[visual hedge]

Nah, not error. The code

[teal viper]

What they mean here is that you can assign a value to transform.eulerAngles.

[radiant frigate]

so i should think of transform.eulerAngles as another variable?

and modify it outside ?

[teal viper]

Variable or property, yes.

You can check the documentation for it and see that it's not a method.

[visual hedge]

Cause pretty sure
'''cs
Instantiate(bullet, transform.position, Quaternion.Euler(0, 0, zRotation);
'''
should work

Damn

[radiant frigate]

if i remove the parentheses it tells me that i cant convert a vector3 into a quaternion

i readed the compile error

[visual hedge]

Ofc you cant.
Your zRotation should be
private float zRotation = 45f;

[teal viper]

Can't read your thoughts... We do t know what you have...

[radiant frigate]

its 60 but ig its the same

[visual hedge]

Then do it. I don't believe it gives error

[teal viper]

Check the Instantiate docs. The third parameter should be a quaternion
