a maker style game

#

i’d call it a chemistry platformer

#

right now, I see the responsibilities, and I’m trying to untangle this mess that I made when I first started following a tutorial last June

#

i don’t have need for any state machines, as this should be doable with very pure functional programming. but I had originally followed a very OOP-heavy tutorial when constructing that, which has a fuckload of variables and mutation, to keep function signatures with 0-1 arguments

it doesn't seem to log anything besides the BeforeSplashScreen callback. would it help to paste the logcat-logs here?
most relevant warning to my eyes is this one;

ah, that is alarming...

This is kinda dumb right? I was thinking to use this as an abstract class then certain behaviors would be able to add or remove themselves.

Hi I'm working on the grounding for a rolling ball game where gravity can dynamically shift to any direction:

Untitled.png
#

This is the best implementation I've been able to think of but don't know how to go about generating the conical cast/collider

#
  1. The cone will always follow the gravity vector
  2. I'd like the cones height and radius to be adjustable but this isn't a must have feature

Is there any way to make maybe a circular Frustum or to separate a part of a sphere collider? If all else fails I'll look into generating a mesh but would like to find a Spherecast equivalent if one exists

glacial linden
leaden ice
#

that's not really a cone btw, more of an arc

reef garnet
#

it's a 2d representation of a 3d game

#

but thanks for the suggestion

leaden ice
#

Spherecast then - but it's a spherical segment still. A cone wojuld have a flat base

hello guys, im using the unity free assets third person controller on android. but the ui controllelr camera movement is way too fast. how can i slow it down ?

leaden ice
#

do you understand the difference between a cast and an OverlapSphere?

reef garnet
#

ah right I was confusing the two

leaden ice
#

and not Dot product - Vector3.Angle

(which does use dot product internally)

#

Well tbh I'm not sure what you're trying to find out with this

#

but I think it follows what you were asking above

reef garnet
#

basically cuz gravity can change I need a dynamic way to detect ground for when I want to jump
This is the method I came up with and was doing research on it, I was hoping for a solution that would stick to the sphere segment but spherecast works perfecly fine

image.png
leaden ice
#

So this is just a grounded check?

reef garnet
#

pretty much but I will also be using the vectors to calculate jump direction

leaden ice
#

Do you want the jump direction to be based on the surface normal? I don't think you even need any of the angle stuff

#

just a spherecast in the gravity direction and use the normal of the RaycastHit as the jump direction

reef garnet
#

it depends on the slope and the gravity direction

#

if Gravity is straight down and the player is on a 70 degree incline you shouldn't be able to jump

leaden ice
#

got it, so yeah then you can do the angle thing

reef garnet
#

thanks for the help

# glacial linden I understand. I'm not sure when this would even happen, but what if the thing I ...

Then you might wanna reconsider your structure. I cant really imagine a scenario where you NEED an object to not be a monobehaviour, have access to the update loop, and also subscribe itself to a monobehaviours update loop. This doesnt even really make sense. How would you invoke these events if it wasnt a mono? You can manually call your update method from a different monobehaviour script, but what you're currently doing is just not needed.
It doesnt make sense for a poco to subscribe itself to a mono anyways, because 1 how will you find the component and subscribe, 2 the poco is gonna have to live as a field on a mono or else it wont exist. The mono has access to the poco, so just manually call the methods

hey guys i have this code for changing characters in relay, but i cant seem to make it change the character in everyones screen. like for example if there are 2 clients they see eachother as the base character and dont change but the clients see the change in the server, and the server sees the change in the cllients.
how can i fix it ?

whats the difference and general usecase of using a class or a struct to make nested dicts

#

what are the pros & cons

tawny elkBOT

#

tell me if i missunderstood your message

#

after some readin i understand more their difference.
i guess i'll use class and see if i dont run into an issue

lean sail
#

Should be pretty rare to actually need one

round violet
#

im using a csv to read it and building a dict

i finished everything, but default unity dicts arent serializable, so i got to change that

image.png
#

my goal is to get the % (int) from two params (same enum)

#

also why are nested dict bad ?
i used tons of time nested list and/or dict, very usefull (in c# and other languages)

lean sail
leaden ice
#

But yeah why do you need a nested dictionary?

#

nested dictionary is very wasteful when you can just use a single Dictionary.

#

If you want a dictionary for this table that's just a single dict. You can just use a tuple (or custom struct) of the pair of those enums as the key type

round violet

e.g.

Dictionary<(LootType, LootType), float>```

i forgot tuple exists

It doesnt even have to be a tuple, could be class or struct but all of them work

Can you add methods with parameters to Unity Events? I have one that takes a string I want to add

if anyone knows some perf testing, please tell me

leaden ice

make it a UnityEvent<string>

indigo drift
#

Gotcha thanks

:)

lean sail
#

The performance really shouldnt be considered even, use what is easiest. I would do what praetor suggested, as with the 2d array I stated a downside of needing some way to look it up

indigo drift
#

There’s something that I wanna know because when I add a method in the inspector before playing— like an OnClick event, it doesn’t go away when I use the RemoveAllListeners function. It will only remove methods I add to it during runtime. Is it a different thing or are the inspector added methods just kind of stuck there?

Event actions added in the Inspector are considered PermanentListeners and can only be removed in the Inspector

I don't really see a use case for removing persistent listeners at runtime

hello guys, im using the unity free assets third person controller on android. but the ui controller camera movement is way too fast. how can i slow it down ?

leaden ice
#

either on the controller script or on the cinemachine virtual camera

deft dagger
#

it becomes like this when i move the joystick to maxright

leaden ice
#

look on the vCam

#

is it a FreeLook?

#

CinemachineFreeLook has sensitivity

deft dagger

this is the virtual camera i use

leaden ice

deft dagger
leaden ice
# deft dagger

ok you'd need to add a look sensitivity to the script then

deft dagger
#

but what would the value even be ? the camera thing is way too fast.
would it be something like 0.1 or something ?

leaden ice
#

you'd have to show the code

deft dagger
#

i think i just need to add a *value that is smaller than 1 here

yes, in other words - a look sensitivity

#

would anyone like to review my code? I'd love tips on how to improve as I've only been coding C# about 6 months now (though I come from other languages like Java)

https://pastecode.io/s/3a4dkz3i

#

In case it wasn't obvious, that's the script for movement of the player character, including activating animations such as sitting, and actions such as going to sleep

leaden ice
hybrid orchid
#

Yeah you've got a point

#

is there anything else besides that?

leaden ice
#

Some questionable formatting, e.g.

if (state == 0) {_dayCycleManager.StartCycle();}```
Some wasteful calculations such as:
```cs
_animator.SetBool("isSleeping", (state == 1) ? false : true);```
Which could be:
```cs
_animator.SetBool("isSleeping", state != 1);```
or
```cs
isLocked = (state == 1) ? false : true; ```
Which could be:
```cs
isLocked = state != 1;```
#

Questionable whether you need both of these parameters if they're just opposites:

        _animator.SetBool("isRunning", _isRunning);
        _animator.SetBool("isWalking", !_isRunning);```
#

You also seem to be using int in a lot of places where you should just be using bool?

heady iris
#

so I have a bit of a nuisance here:

I have a few singletons that live in DontDestroyOnLoad. They are supposed to live forever -- created on game start or when first needed, and never destroyed until the game quits.

I just fixed a bug where I forgot to unsubscribe from an event on such a singleton. However, this is now causing a new problem: when the game quits, a component tries to unsubscribe. But the singleton is already destroyed, so the singleton class tries to create a new instance of the singleton.

This makes Unity complain that I created a game object during OnDestroy.

I'm thinking of a few solutions here:

  • Have the singleton GameController detect when the game starts quitting and set a static field. When this field is set, the singleton's Instance property always returns null. This causes a big pile of errors, but the game is quitting, so who cares?
  • Same as above, but return the reference to the now-destroyed singleton. This is fine as long as I don't need to touch any Unity properties.
  • Have individual listeners detect when the game is quitting and decide not to try to unsubscribe when they get destroyed
#

to be honest, these singletons could just be plain old C# classes if I didn't need to assign some references to assets

#

dammit, one uses Update

leaden ice
heady iris
#

I guess that works. I do something similar in other situations

#

like stopping an object from unsubscribing if it was never initialized and subscribed in the first place

Thanks. I changed the calculations, as for the formatting, i just like to do that to keep it simple so I guess it's just a personal preference, unless you recommend keeping it spaced out.

I do need two parameters though. if i dont have it, it ends in an infinite loop bc there is a difference between walking and running and it needs to know when to idle and when to not idle animation

and im gonna look into state bc i remember there was a reason I made it an int but i cant remember, but now im definitely going to start adding comments everywhere in my code lmao

#

nvm i remember now, it's because unity's animation events don't support boolean as a function

heady iris
#

so I have Domain Reload disabled for MAXIMUM SPEED

#

which means all of these static fields are sticking around

#

if I only create a new instance if the instance field contains a genuine null, and not a destroyed object, then it breaks the second time I play the game

#

I think I can work around this by recording when the game quits on each singleton and refusing to create a new instance once the game starts ending

#

I remember Loup talking about this recently

I came across these two errors while making a custom EditorWindow. I am not sure if they are connected but they seem like they could be related and I can not figure out either of them. The errors are always thrown together and they only get thrown the first time the Window is opened after launching unity or recompiling the code. I have tried the solution provided by this thread (https://forum.unity.com/threads/avoiding-you-getting-insane-because-of-invalid-guilayout-state-errors.1429669/) but the errors still happen (I think its because it is happening on GUILayout.BeginVertical(), not GUILayout.EndVertical() so it is still getting run even with the try{}finally{}). Everything still works properly even when the errors get thrown but I would still like to fix them.

#

This is only a problem in the editor

#

blarg. i will think about this when i DON'T have a cold

#

I'll just make the single offending component not try to unsubscribe if the game is already quitting and come back to this one ltaer

somber nacelle
#

i recently had similar issues with a lazy loading singleton and ended up just not making it lazy loading. though you can do something like give the singleton implementation some method or property that checks if it is null and check that before attempting to unsubscribe

heady iris
#

ah, that's an idea

#

I was trying to check if (MySingleton.Instance) was null-y

#

but that winds up creating an instance!

#

a separate method would do the trick

#

perfect, thanks 👍

somber nacelle
#

another alternative would be to make the event static. of course depending on what the event is used for that may not be ideal, but at least then it wouldn't be tied to the singleton instance

When a breakpoint is hit, it naturally freezes the program execution.

#

Does it not resume, when you press the "resume" button?

modern creek
#

VS freezes - can't step/break/anything

cosmic rain
#

aah

modern creek
#

So.. I start the game (in unity), tab to VS, set a breakpoint, start the debugger process, tab back to unity and do the thing, hear the breakpoint sound (I have my own sound set in the OS) but VS is non-responsive.. and then unity becomes nonresponsive shortly after

#

It's not even an interesting breakpoint - just a logging call at the beginning of a method I wanted to step through

cosmic rain
#

Did you try connecting the debugger first, making sure that it's connected correctly and then setting the breakpoint?

modern creek
#

Yeah

#

For another client and project, they're on 2021.3 and I have occasional issues connecting (apparently a known-ish? issue) but 2022 and 2023 both seem to connect without any issues, even with multiple instances of unity running

#

Not the sitch here though, one instance of unity running, one instance of VS running.. pretty vanilla workflow to be honest

#

I don't even see any stack traces in this from my codebase.. a bunch of IO stuff, perhaps?

#

But I can't tell if that's a visual studio thing, a mono thing, or a me thing. For what it's worth, the area of code I'm breaking in/around is some file reading stuff, but the breakpoint is way before any file ops, and this works just fine when I'm not in debug mdoe and breaking

im having trouble with this new feature im trying to add to my game, I decided to learn game dev by trial and error, while it's not hte best approach it's what I enjoy doing. But I'm attempting to have this health bar spawn above the rocks in my game. Every time I click a rock it's supposed to shorten the health bar, and when the rock is destroyed so is the health bar. Everything actually functions great, other than the fact that the health bar spawns in the middle of the screen no matter what, and follows me around, I'm assuming it's because it's a UI element, but I don't know how to fix i

If it’s following you, you likely need to make it a world space canvas so you can position it. If it’s in screen space, setting the position won’t do anything, and it will always be fixed on your screen.

i did try that, i assumed that was the problem, but i couldn’t get it to show up anymore when i did that, im sure i’m just totally missing something in there

teal parrot
# peak pond i did try that, i assumed that was the problem, but i couldn’t get it to show up...

Did you remember to scale it down? Screen space canvases are set to be very large so when converting to world space you might need to scale it down. Are your sprites on game objects or in a screen space canvas? If they are in a canvas it might be overlayed on top, in which case you will need to somehow layer them (not sure how to do that), or you could put them in the same canvas and just update the position of the bar directly with transform.position or some other means. If it’s not in a canvas, you might need to move it along the z axis to be in front as well.

peak pond
#

i think you’re onto the right track with that, it’s definitely something with the layering or the order of everything, i probably didn’t layout everything right

#

i’ve been just kind of adding new things as i go learning how to do stuff

#

my hierarchy is likely in shambles

#

but nothing is in a canvas i can say that much

teal parrot
#

If nothing is in a canvas, then positioning and optionally parenting them to the rock, ensuring the scale is normal, and ensuring it is in front of the rock should work as a solution.

#

I’m sure your hierarchy isn’t that bad :)

#

I have to go now so if you need help I probably won’t be able to respond.

Hey Guys 👋
im trying to make a pickup system but am having some difficulty
here is what i have so far
the current issue im having is i can pickup and drop items just fine
i just cant use them
basically i want to pick them up and for example for grapple assign a camera and player transform so that grapple can be used by the player who picked it up
and so that when they drop it, these got assigned to null so that when another player picks it up they can use it
much appreciated guys

#

Basically the inventory script handles weapon switching and all of that, equipable is assigned to the item that wants to be picked up and interaction manager handles the input

west lotus
#

So what trouble are you having ?

white crater
#

there are scripts on the items being picked, for example weapon or grapple, and those require camera or player transforms to be assigned through the editor

#

but like im tryna make it for multitplayer so that when a player picks up the item, it assigns their camera or whatever is needed to the item

#

and then when you drop, it removes it

west lotus
#

So Get a reference to the weapon script and a reference to the player doing the pick up an assign what ever you want

#

Have you tried that ?

latent latch
#

The camera is client side

#

and you should have that information all available anyway for local player

west lotus
white crater
#

ill try it out, maybe im just overthinking it

latent latch
#

im not seeing any networking code here

#

or wait you mean local?

white crater
#

no its not networked yet

latent latch
#

Well, usually networking libraries have a implied service locator pattern (client key) which is something to read into. Consider netcode for gameobjects before designing too much of the project without understanding what needs to be adjusted for.

white crater
#

im using photon pun2

#

ill do some research into that service locator pattern

latent latch
#

Photon has their own discord too which you'd probably get more help out of honestly, otherwise can always ask in #archived-networking

#

I've not used it but my mate made some quake shooter in it which turned out pretty good

white crater
#

is netcode easy? havent looked into it much

#

just got recommended to use photon

latent latch
#

netcode is easy to jump into, but there's reason to go with photon if you were making something fast paced like a shooter

#

at least that's what I've been told haha

#

something along the lines of how interpolating is implemented currently with netcode as it is* still being developed

white crater
#

interpolating is super smooth in multiplayer, atleast from what ive tested with my movement

Hello all! I have a scroll rect that contains credits text inside. I want it to onenable start from the top and starting scrolling down. However, if the user scrolls up or down or grabs the scroll bar performing the same action, it stops the scrolling from happening.

My code should work, however, the listener is detecting when the scrolling is occuring, however, its detecting its own scrolling resulting in it not to scroll at all because it stops as soon as it starts.

I need to change the way the event is triggered or add some sort of if statement inside of the StopAutoScroll() function that checks if its user input or computer input. I just don't know what to do for that! Let me know!

    private void OnEnable() {
        scrollRect.verticalNormalizedPosition = 1;
        shouldAutoScroll = true;
        StartCoroutine(AutoScrollCredits());
        scrollRect.onValueChanged.AddListener(StopAutoScroll);
    }

    private IEnumerator AutoScrollCredits() {
        float targetPosition = 0;
        while(shouldAutoScroll) {
            scrollRect.verticalNormalizedPosition = Mathf.MoveTowards(scrollRect.verticalNormalizedPosition, targetPosition, Time.deltaTime * creditsScrollSpeed);
            yield return null;
        }
    }

    private void StopAutoScroll(Vector2 position) {
        shouldAutoScroll = false;
        scrollRect.onValueChanged.RemoveListener(StopAutoScroll);
    }
latent latch
#

so the problem is you dont want the user to interact with the scroll?

#

you can disable the raycast on the scrollrect probably

fallen lotus
#

i want it to scroll until the user scrolls and then i want it to stop

#

think of it as the credits are scrolling but then you want to look at a specific credit so you scroll back up to it. right now, it keeps scrolling after you scroll up but i just want it to bassically turn back into a normal scroll rect

latent latch
#

has a bunch of interfaces you could probably look into

fallen lotus
#

yeah i just couldnt find anything when i looked

#

thats why i came here

latent latch
#

Maybe thinking of maybe adding checking for input in OnDrag() perhaps for user input

#

maybe implement ISelectable or IPointerHandler some other ideas

fallen lotus
#

if you have any more dont hesitate to let me know

latent latch
#

kinda tricky cause using the scroll methods wouldnt work too well if you are already moving them

#

so my idea is detect a raycast from the user

fallen lotus
west lotus
fallen lotus
#

ill proboally do it just like this

somber nacelle
#

i'm surprised that scrollrect doesn't have a setwithoutnotify method like a lot of the other ui objects do

west lotus
#

Or you know…a autoscroll api

fallen lotus
west lotus
#

Its like Unity don’t have a coherent and comprehensive UI solution that fits modern design needs or something. But hey at least the abandon it and are working on a mew UI solution haha haha. Making UI in Unity is such a joy haha

fallen lotus
#

haha

#

i wish there were ways to better create symmetry

#

like if i select a group of buttons, i wanna space them evenly without using an auto sizer

#

or if i wanna place that group in the exact middle, the snap just doesnt happen

#

even to get rounded edges i had to install a package that does that lmao

hey I have a quick question I hope someone could help me with

#

is there a way to detect if a mouse is present

#

that works on both pc and mobile

#

fyi : you can use a mouse on ur mobile with a micro c to usb converter or a bluetooth mouse in general

#

so i wonder if theres actually a way to detect if a mouse is present

i really hope someone is awake at this hour, im quite new to game dev and am trying to implement an inventory, I'm stumped right off the start for a reason I cant seem to understand. I made a class for my items, and when I try to use it in my other Inventory script I keep getting an error saying that the Item class doesn't contain a constructor that takes 2 arguements, im sure the answer is simple, please help me understand

# 
{
    public enum ItemType
    {
        Rock
    }

    public ItemType itemType;
    public int amount;
    
}```
#

thats my class

# 

    private List<Item> itemList;

    public Inventory()
    {
        itemList = new List<Item>();
        AddItem(new Item (Item.ItemType.Rock, amount = 1) );
        Debug.Log(itemList.Count);
    }

    public void AddItem(Item item)
    {
        itemList.Add(item); 
    }

}```
#

and my inventory

#

it wont even take one though, I tried that

lean sail
#

I wouldnt though, because you (probably) want to enforce how an Item is constructed, you dont want to have it be done with just
= new Item()
and all the values are uninitialized or left to its default value

peak pond
#

honestly my whole problem was that I wasn't using the "{}" and was instead using "()" i feel dumb

lean sail
#

in this case, you do want to just pass in the values through the (). you wont have to write itemType = and amount =
Plus what i said above about enforcing how an item is constructed

#

it would just be new Item (Item.ItemType.Rock, 1)
Not really sure what the enum is gonna be used for tbh, it looks somewhat questionable to have

peak pond
#

honestly I've been watching a video helping with adding an inventory, this is really just a passion at the moment, so I'm learning as I go kind of hands on, leading to obvious holes in my knowledge

#

the person in the video used enum, i'm not too sure why

#

I usually go back after making something work and try and understand it all

#

I'm still getting an error with the constructor not having two arguments

#

after using the code you reccomended, it feels like there is something wrong with the item class

west lotus
#

Show your new code

peak pond
# 

    private List<Item> itemList;

    public Inventory()
    {
        itemList = new List<Item>();
        AddItem(new Item(Item.ItemType.Rock, 1));
        Debug.Log(itemList.Count);
    }

    public void AddItem(Item item, int amount)
    {
        itemList.Add(item); 
    }

}
lean sail
# peak pond the person in the video used enum, i'm not too sure why

beginner tutorials are often shit and not code you would want in a final game. Its more for the purpose of showing you. The enum sounds questionable because i doubt you want to be handling specific logic based on it, but we dont really need to change it if itll just cause more confusion

#

AddItem should still just take 1 parameter, that isnt the constructor. Look at the w3 link i sent, the ctor should go inside Item

west lotus
#

But just go and define a constructor in the item class

peak pond
west lotus
#

I would not use chatgpt to learn

peak pond
# 
{
    public string name;
    public int amount;

    public Item()
    {
        name = "Rock";
        amount = 1;
    }
    
}```
west lotus
#

Its a language model it spwes out what it thinks you WANT to hear

peak pond
#

would that constitute a constructor

west lotus
#

You want to put two parameters in the construcot and assign them to the members of the class

peak pond
#

i agree, i take it all with a grain of salt with beginner resources and definitely chat GPT, game dev is a big passion for me, so I find it hard going through courses, I just want to create

lean sail
#

You'll take longer to learn c# and unity at the same time, compared to just learning c# and coding basics then doing unity. Itll be harder to understand why things dont work, like if it's a unity issue or your own logic issue for example

peak pond
#

I've definitely been doing the experimenting route, probably a bit too hard, but I understand that, I just seen a lot of people saying you dont need "that much" coding experiance to make things work

#

so I kind of just jumped into it and thought I could learn as I go

#

and I've definitely learned quite a bit, but I run into very hard walls sometimes

#

like this wall, and I'm sorry guys, but I'm still a bit confused

#

how should I have made the constructor differently. not given it direct values

west lotus
#

The constructor is just like any other method

lean sail
west lotus
#

It can have paramaters

peak pond
#

i do understand that

lean sail
peak pond
#

i have this now

# 
{
    
}
lean sail
#

You got your types messed up there, you want to use the same type as the fields

#

Amount is a number

peak pond
#

i didn't mean to reply to that

lean sail
#

The link I sent before also has an example with parameters in the constructor, it should show you what you need to do with those values now

peak pond
#

i got it working now, thank you very much, I think i'll maybe do some code only learning, it's just too fun seeing things actually work in a game lol

Not sure where to post this so I may paste this in other channels, but in unity, is it possible to have "plane shifting" as a mechanic? In other words, the player is able to switch between two states of the same level, with there being differences of geometry

dusk apex
static horizon
#

i.e being able to jump between two variations of the same level

#

for a puzzle game

dusk apex
#

So break the problem down.

  • Load two levels
  • Jump between two levels
west lotus
#

To the levels share the same space?

#

I.e multiple realities type of deal?

#

Or are we thinking with portals here?

static horizon
#

I was going to bind it to a button press w/ cooldown

#

The idea is that its similar to a top down dungeon crawler, but youre able to jump between two variations of the room to complete puzzles

west lotus
#

Thats not answering my question, maybe try to provide some references to the desired effect

static horizon
#

got it

#

ahh ok

#

a good example would be void jumping within titan fall 2s campaign

#

in this case, the player is able to jump to a variation of the level where theres no fire covering the floor, allowing them to pass

dusk apex
#

You'd just load two worlds (or one with both) and have some objects active and inactive relative to whichever world you're in.

static horizon
#

kk

#

thank you!

white crater
#

anyone know how to add good camera effects say when you land from jumping like cluster truck

#

(idk how to do the camera offset? or shake?)

so that paired with a slight offset to the camera to make it go down and up gives it that good feedback?

some features etc that work in the editor. It doesn't work after build. What could be the reason for this? Or is there a way to debug the built game?

unreal temple
peak raptor
#

My problem is that the buttons or canvases shown in this editor do not work when built.

unreal temple
#

The buttons do not respond to clicks?

peak raptor
#

Some buttons do not appear in the canvas, but there is actually no reason why they should not appear. It should appear at startup. It appears at startup in the editor. Some of them don't work

dusk apex
#

Are your gui anchored properly?

#

That would normally be the difference between Editor play Window and standalone Window - size.

Or Editor zoom etc

Do files within the source need to be moved manually after creation? Could it be because of this?

Hello! Could anyone give me some ideas to make to 1. Learn C# and 2. Learn the ropes of Unity. FYI, I have a strong knowledge of C++, if that changes anything. Thanks!

dusk apex
lime niche
#

🤔 , What would you recommend a beginner to C# but has knowledge of C++?

#

Something that's probably exclusive to C#.

dusk apex
#

Depends what you're needing to integrate.

lime niche
#

Not sure haha.

dusk apex
#

Most who have learned academic C++ are not too strong working with libraries/frameworks/engines. If this applies for you, you'd probably want to get to know more about the Unity callbacks and the execution order of certain methods https://docs.unity3d.com/Manual/ExecutionOrder.html specifically when they occur.

#

Other than that, Unity doesn't really follow the normal standard c# workflow.

lime niche
#

Ah.

#

I'm very familiar with raw C++ but I have used libs and frameworks such as Raylib.

dusk apex
lime niche
#

Ah./

#

So what's the first thing. 😅

loud wharf
lime niche
#

Ah.

loud wharf
#

I think a plenty of people know ref structs and ref parameters, but idk about ref variables.

#

ref variables can only be set with any getters or functions with ref returns.
They also have to be set immediately upon declaration.

#

Array indexer returns a ref.

#

And also Span indexer.

dusk apex
#

Something to be wary of is properties. You'll see a lot of variable-like fields but they may actually be properties (functions under the hood) and getting value type data from the member may have you bewildered.

loud wharf
#

Microsoft name properties and methods the same.

dusk apex
#

transform.position.x = 5 will not work.

loud wharf
#

But unity throws .Net syntax rules out the window.

Does Unity have anything similar to the subsystems of Unreal Engine or Godot's autorun function? Basically a way to run a script without placing it into the world like MonoBehavior? And if no, what's the go-to method for implementing something similar?

hey guys is this the right channel for questions about coding?

#

need help with a script if it is

#

Basically right now I have a very basic bones for a rhythm slasher type game. Right now my script spawns cubes that come at the player. The player must destroy the cubes with a sword. The cubes spawn once every second, and move at a speed of 10. Basically, I want to have it so that every time the player destroys a cube, the spawn timer decreases (i.e the cubes spawn faster). How would I go about doing this?

rigid island
heady iris
#

and then using that to calculate the new spawn rate

(rather than just modifying the spawn rate each time)

Is there an easy way to decide which animation from a sprite sheet to use? Or do I need 1 animation per spritesheet?

latent latch
#

it's just an array of sprites

#

ah, right actually I know what you mean

#

more specifically to using the animator

#

I think there's a way to choose what sprites you want from the atlas and make a whole new asset from it but keeping the reference

#

Try like selecting a bunch and dragging them into the asset window

if you're familiar with the basics, perhaps it's time to jump in and try to make a game - a good idea is to start with a fairly simple one you know and like, and try to recreate it or part of it

rigid island
#

everyone says they know the basics but turns out they don't

oak panther
#

move, collide with object, spawn objects, and game over

rigid island

those are unity specific not C#

#

do you know basics of c# ?
example an Array ? a List?

#

loops

#

without knowing thse you won't get very far

oak panther
rigid island
#

knowing loops is essential when dealing with collections such as arrays

#

if you want to learn Unity better I suggest you dive more into traditional c# and then go back n forth between unity API and c#

leaden ice
#

Yep loops and collections go hand in hand. You can't really know collections without knowing loops

#

Almost anything interesting you can do with a collection involves a loop

(or Linq which is a fancy wrapper around a loop)

but it taught fundamentals

#

Well, get rid of one problem, onto the next; I'm trying to make a Pokémon esque encounter system, you run into grass, or a cave, or into the Pokémon itself and a battle starts, but this isn't gonna be a turn based battle, and controls inside and outside of battle would be different, such as x in battle might a spell, but outside of battle it might be a climb. That sort of stuff. Does anyone know how i could achieve this?

#

I know i'd have to make use of scenes and such, but not exactly how

rigid island
normal arch
#

How would i detect whether it's the battle scene or not, and obviously it would be one scene and not multiple, how would i change the scene based on like what area the player is in, or what enemy they're fighting?

rigid island
normal arch
#

i feel like there's a lot of stuff to do with this

#

so also where would i start?

rigid island
#

eg trigger inside grass would yield a grassy type map/scene

normal arch
#

If i wanted to do that

#

would i need like a save system

rigid island
#

You could but no necessary

normal arch
#

how would i make the variables transfer between scenes

rigid island
#

DDOL can be used for example and make singletons
(ideally you want to inject your references on scene changed)

heady iris
#

Determine if the "overworld" and "battle" scenes are similar enough for it to be worth using the same code and components for both kinds of scenes

#

and controls inside and outside of battle would be different, such as x in battle might a spell, but outside of battle it might be a climb.

So if moving around the overworld contorls and plays way differently, you might just need two different sets of components and prefabs

normal arch
#

ok

#

I'm probably just gonna start by making the scene

rigid island
#

new input system also allows you to easily switch control schema

latent latch
#

multiple scenes for a battle area seems like a pain

#

it's like either deload your whole previous scene, or stick DDOL on every asset so you dont have to reload it again

normal arch
normal arch
heady iris
#

You can break your inputs into separate action maps.

image.png
#

I enable and disable individual action maps based on the current game state

normal arch
#

I'm not even sure where the new input system is

rigid island
#

its a package

normal arch
#

ok

heady iris
#

I can think of a few ways to handle entering a "battle" scene

#

One would be to load the battle scene in Single mode (the default). This would unload the overworld scene entirely.

#

So when you return to the overworld, you would need to restore everything back to how it was before entering the battle

#

This sounds unreasonably difficult. You'd basically need to write a save system that remembers everything about the overworld's state

#

Another option would be to additively load the battle scene, and to just deactivate objects in the overworld until you're done

#

And the last one would be to additively load the battle scene -- but to still stick around in the overworld scene

#

Have you ever played a Yakuza game? When you get into a random encounter, you stay exactly where you were in the overworld

normal arch
heady iris
#

it just spawns in enemies, moves civilians out, and creates some barriers to keep you in the fight area

#

I think that's how newer Pokemon games do it too

#

the problem is that you can get into a fight next to a cliff

#

and go off the cliff

normal arch
heady iris
#

That would be a better fit for a game where you can share some logic between the "overworld" and "battle" situations

normal arch
#

But i'm not sure if it entirely fits what i want with the game

heady iris
#

So it would not make sense for an old Pokemon game where the battles occur in a completely isolated world

#

(and where none of the mechanics overlap)

#

you walk around the overworld and go through menus in battles

normal arch
#

yeah my game isn't turn based, it would be more like a game called crosscode

#

if you've heard of it

heady iris
#

Haven't played that one

normal arch
#

Their combat is like the one where it's additive

#

but there are no barriers

#

if you escape the battle it just ends basically

#

But i feel like this wouldn't fit as some battles could have some obstacles

#

that woudln't be in the overworld

hoary mason
#

how do you turn off a button's ability to be clicked

#

as in, I only want it to be pressed by keys

not the mouse

rigid island
hoary mason
#

so like

rigid island
hoary mason
#

I take out mouse from fire in input settings?

#

aah

rigid island
#

DisableDevice (Mouse.current) should work

hoary mason
#

what if I want to use the mouse in other buttons but specifically not on that button

rigid island
#

make custom button probably with diff conditions

heady iris
hoary mason
#

yeah

heady iris
#

The first thing that comes to mind is just extending Button and overriding OnPointerDown

#

the UI classes are very open to extension!

hoary mason
#

wait

#

would disabling interactable in the button work?

heady iris
#

That would block all interactions

#

Adding a component that implements IPointerDownHandler and uses the event might work

#

But I don't know which order things would go in

#

button first or button second

rigid island
#

yeah you cannot use Button component for that no ? wouldn't it trigger hover events for button?

heady iris
#

the last thing that comes to mind: just put something in the way of the button..

#

a child element that stretches to perfectly cover it

#

and that has an image on it to eat the raycast

#

I'm less confident about that one

#

also, gotta scram in a minute

hoary mason
#

I think for now disabling all the interactions works for me, since the way I want to use it it doesn't need to be selected, so i'll add a component that sends the button's pressed signal when I hit a key (basically I have a very specific use case where I want to call the button's pressed signal but don't want to be able to do it by mouse)

root.AddTorque(Mathf.Clamp(90f - root.rotation, -uprightStrengthClamp, uprightStrengthClamp) * (90f - root.rotation));

Is anybody able to help here? I have no idea why but it'll rotate fine at first and then go mega slow for the rest of the rotation

#

root is a Rigidbody2D and uprightStrengthClamp is to stop the adjusting value from being too high and overshooting

#

At around 45 degrees it seems to want to go mega slow for no reason. This only happens when I multiply it by (90f - root.rotation)

clever lagoon
languid hound
#

I did actually look at this I tried using transform.rotation.z as root.rotation is in the thousands for some reason but they both give the same results

heady iris
#

transform.rotation.z is especially wrong

languid hound
#

Which I find shocking since they're marginally different numbers

heady iris
#

that's the Z part of a quaternion

#

which is not an angle

#

it sounds like a bad idea to try to subtract an angle from a constant like that -- you'll get very different results depending on whether that angle is negative or positive

#

You can use Mathf.DeltaAngle to measure the distance between two angles

#

Mathf.DeltaAngle(-45, 90) would be 135, for example

languid hound
#

Holy shit thank you for sharing DeltaAngle

heady iris
#

there are several "angle-aware" methods in Mathf

languid hound
#

I'm not kidding I was looking for something

#

Exactly like that

heady iris
#

LerpAngle, SmoothDampAngle, etc.

#

no prob (:

#

you can also compare transform.rotation to another Quaternion with things like Quaternion.Angle

#

so, for example...

# 
Quaternion.Angle(transform.rotation, Quaternion.LookRotation(Vector3.right))
limber wharf
heady iris
#

this would measure how many degrees you're off from a rotation that looks to the right

languid hound
#

DeltaAngle fixed it

#

Fucking finally you don't know how overjoyed I am to find out that exists

#

I saw a shortest angle method being used in quite a few things

#

I thought it was some math bs

#

Sorry I'm not well versed in all the really specific functions for quaternions and vectors or mathf etc,

Landing on the ground isn't resetting hasJumped

clever lagoon
#

I've got this code in a loop...
if(displayElement is ITriggerOnClick clicker) { clicker.onClickEvent.AddListener(() => { onClickEvent.Invoke(i); }); }

The value i MAY be different from the last time the loop was run. So, I need to "RemoveListener" - specifically the one I preiously set (if any). I assume I'll need to store/cashe the "last listener" for each of the clicker objects- so I can pass it to RemoveListener- Question: Is there a better/simpler way to do this?

heady iris
#

so if you jump, land, and then fall off a platform, hasJumped will remain true

#

you'll correctly decide that you should be allowing a jump with coyote time, but since hasJumped remains true, the jump fails

#

you will need to constantly check for ground and reset hasJumped proactively

swift falcon
#

Otherwise i will be = end of loop val

heady iris
#

languid hound
# languid hound DeltaAngle fixed it

I was wrong forgot to apply the other math.. it still randomly goes at awfully slow speed for no reason at times.. still greatly appreciate DeltaAngle though

oak panther
#

so with the arrays with we have like

string[] cars = {"bmw", "ford",}

is the curly brackets refering to the array and adding?

heady iris
#

This is not valid syntax.

oak panther
#

its a examply

swift falcon
#

I dont think theres a better way other than being outside the loop context @clever lagoon .e.g.

for(int i = 0; i < 10; i++) {
    DoSomething(i);
}
heady iris
swift falcon
#

Then you have everything in DoSomething

#

Instead of using i directly

oak panther
#

im refering to the c# class im reading

clever lagoon
heady iris
# 
List<int> numbers = new List<int> { 1, 2, 3 };

The collection initializer tells C# what things you want to insert into the collection when it's created

oak panther
heady iris
#

It's equivalent to adding the items after constructing an empty list

oak panther
heady iris
#

and they contain items that need to go in the collection

mental rover
heady iris
#

My example used a list.

oak panther
oak panther
#

you can do it in order or pick something or do something in random order

#

or even refer to something

mental rover
#

it's literally just syntax to initialise the array

oak panther
swift falcon
heady iris
#

I think it is true that arrays use an object initializer, rather than a collection initializer, though

#

The distinction isn't very important here, but it is there.

#

Either way, you specify the items you want in the curly braces.

oak panther
#

to referred later on right

dusk apex
#

To be specific, that's an assignment operator

#

You wouldn't be able to modify the size of an array after declaration - not able to add to an array

heady iris
# 
int[] arr = new int[] { 1, 2, 3, 4, 5 };
#

this winds up creating an array that can hold five ints

swift falcon
#

yes

dusk apex
#

And the values are 1, 2, 3, 4, and 5

But when i try to apply the var's value to the right boxhelp it doesn't work... What could happen? The right boxhelp changes it's vertical size to a really small one and it doesn't do nothing with that code```csharp
boxHelpHeight = GUILayoutUtility.GetLastRect().height;
Debug.Log("BoxHelp Height: " + boxHelpHeight);

// RIGHT BOXHELP
EditorGUILayout.BeginVertical(EditorStyles.helpBox, GUILayout.Height(boxHelpHeight), GUILayout.Width(EditorGUIUtility.currentViewWidth * 0.25f));

so then it's doing integer division

okay correct me if I'm wrong when I create a new custom class-

that string variable doesn't exist yet until i define in a main class and give it a object name so i can refer it to a Consol.WriteLine()

class CustomCar
{
  string carName;

  static Void Main (string[] args)
{
    CustomCar Car = new CoustomCar();
  car.carName = "Ford"
}
}

right?

sacred sinew
oak panther
#

i've probably spent 30 minute trying to figure out what it trying to tell me even looking on a different website

leaden ice
oak panther
leaden ice
#

that's just the name of your variable

#

it's not a name of the object

#

it's the name of a reference variable pointing to the object

#

the new bit is creating an object

#

Car Ford = is making a variable of type Car with the name Ford. This variable is simply a reference to the object you created with new

#

If you did Car x = Ford; layer you would have two references ("x" and "Ford") pointing at the same object.

oak panther
#

so the object is already created I just need a new referencing point so it can access it

leaden ice
#

new creates the object

#

Ford is a reference to the object

#

you need to save the reference in a variable so you can do things with it later, yes

#

otherwise you won't have any way to retrieve it.

oak panther
#

so when I create a new class and start putting empty variables in it I wont be able to access it until I reference the class somewhere else and give it a name and a new object

the car simply needs to exist and you need a reference to it

a variable is a way to hold a reference to it

but not the only way

oak panther

it can be accessed by other classes

hello I am a beginner
I am making a cheap knock off of angry birds and I would want the bird to follow the mouse when I hold left mouse button

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class FireInTheHole : MonoBehaviour
{
    // Start is called before the first frame update

    public Rigidbody2D rb;
    public Transform trans;
    private Vector3 mousePosition;
    private Vector3 mouseWorldPosition;

    private bool isOverlaped = false;
    private bool isHeldAndOverlaped = false;
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButtonDown(0) && isOverlaped)
        {
            isHeldAndOverlaped = true;
        }
        else
        {
            isHeldAndOverlaped=false;
        }

        mousePosition = Input.mousePosition;
        mouseWorldPosition = Camera.main.ScreenToWorldPoint(mousePosition);

        if (isHeldAndOverlaped)
        {
            trans.position = new Vector3(mouseWorldPosition.y, mouseWorldPosition.x, 0);
        }
    }

    void OnMouseOver()
    {
        isOverlaped = true;
    }
    void OnMouseExit()
    {
        isOverlaped = false;
    }
}

this is my code and for now when I hold the button the bird teleports a few pixels to the left of the mouse

quartz folio
#

why do you flip the x and y positions?

hybrid jungle
#

anyway the teleporting is fixed the problem now is that it only does it once it will snap to the mouse for only one frame

quartz folio

you only use GetMouseButtonDown

#

which is a single frame when you click

#

how to make it continuous ?

I have a super silly, general question

I typically have methods named SetFoo(some parameter), and by my own convention, when I have "Set" in the method name, it implies that some value can be passed to the method and that value will be used to "set" whatever foo is.

I'm looking for a name when there is no parameter; when the method is responsible for handling the assignment logic based on class level members value.

e.g. some custom level editor where a tool is stored at class level. The method can infer the "editing mode" from the tool selected, so there is no point in passing a parameter. By my own convention, "SetFoo" would be misleading since there is no parameter being passed and the method actually figures everything out by itself.

I'm hoping one of you has a similar naming conventions and has handled this before.

Does anyone have the opus decoder script i accidentally deleted it on my game

untold siren
#

if I'm trying to implement a reference to whether my character is carrying any weapons, would it best to do it via a dictionary?
I'd need the following things referenced:

  • bool to show if they have the weapon
  • two floats, one for primary ammo, one for secondary ammo
  • component ref to the weapon script of said weapon
#

sounds a bit easier than having to create a lot more individual variables

#

well ^ I'd need multiple structs for each

west lotus
#

Why does the player care about ammo? The weapon should store its ammo

#

Also the bool seems redundant. If you have a List<Weapon> you already know what weapons you have

#

And you have a reference to their exact script

untold siren
# west lotus Also the bool seems redundant. If you have a List<Weapon> you already know what ...

for ex I'd like the player to be able to collect ammo whilst not having a certain weapon picked up

i.e. collect shotgun ammo but not having shotgun equipped so that they can pickup a shotgun later and manage to have reserve ammo

this is on the player shooting script, which handles weapon cooldowns, reloading and weapon firing - I could offload this onto a script for the weapons themselves but still TE_Shrug if the player doesn't have a weapon collected then said weapon script wouldn't be active

#

unless I keep ammo stored on the player themselves and then have each weapon script directly reference the players ammo

west lotus
#

Ok so now we have some context

untold siren
#

and also interacting is done on PlayerController.cs for example:

        private void Interact()
        {
            var rayOrigin = activeCinemachineBrain.gameObject.GetComponent<UnityEngine.Camera>()
                .ScreenPointToRay(Mouse.current.position.ReadValue());
            if (!Physics.Raycast(rayOrigin, out var hit, maxInteractDistance)) return;
            switch (hit.transform.root.tag)
            {
                case "Weapon":
                    var collidedWeapon = hit.transform.gameObject;
                    var collidedWeaponScript = collidedWeapon.GetComponent<WeaponScript>();
                    var collidedWeaponObj = collidedWeaponScript.Weapon;
                    playerShooting.Equip(collidedWeaponObj, collidedWeaponScript);
                    Destroy(collidedWeapon);
                    break;                                              
                
            }
        }

and then my script PlayerShooting.cs handles equipping of said weapon:

        public void Equip(BaseWeapon weaponToEquip, WeaponScript weaponScriptToEquip)
        {
            activeWeaponScript = weaponScriptToEquip;
            activeWeapon = weaponToEquip;

            _activeWeaponPrimaryAmmo = activeWeapon.WeaponPrimaryAmmo;
            _activeWeaponSecondaryAmmo = activeWeapon.WeaponSecondaryAmmo;
            
            switch (activeWeapon.WeaponVariant)
            {
                case BaseWeapon.WeaponType.Hands:
                    break;
                case BaseWeapon.WeaponType.Pistol:
                    pistolObject.SetActive(true);
                    break;
                case BaseWeapon.WeaponType.Rifle:
                    break;
                case BaseWeapon.WeaponType.Shotgun:
                    break;
                default:
                    throw new ArgumentOutOfRangeException();
            }
        }

Im going to suggest that you re-do your design. Storing the weapon type in a enum in a SO just seems bad to me. Try to have a abstract Weapon class and then Pistol: Weapon Rifle:Weapon etc where you override with the specifics for that weapon. As for your question I would still delegate all that to the Weapon class. You can have a iscollected bool that lets the player actually equip it and I would then start the player off with a ready List of all weapons

untold siren
# west lotus Im going to suggest that you re-do your design. Storing the weapon type in a enu...

Makes sense, seems a lot easier to re-approach my implementation than to begin messing around with dicts and structs - good thing I asked this now and not even further into development.

I'm assuming to set a certain weapons type I'd then follow up with an enum within a monobehaviour class to indicate which weapon type is being used and then handle the values etc through the subclasses?

west lotus
#

No need for enums

latent latch
west lotus
#

Each weapon type is its own class inheriting the base abstract Weapon class

untold siren
west lotus
#

For example you have Weapon and you have Shotgun. What happens if you now want a sawed off shotgun? Case 1 you change the enum and now you go everywhere where you do a switch or check of that enum and its horrible. Case 2 you simply create a new class SawedShotgun:Shotgun code the specific implementation in that class and you are pretty much done.

let's try something a little different. instead of passing your json to the SetString method, pass literally any other string and see what it prints in the log.
I have a feeling that it's just not writing to playerprefs so you're getting an older string

most likely your editor does not have write permission for your registry anymore for whatever reason. (assuming you are on windows)
i've mostly only ever seen this happen when someone changes an editor setting like their external script editor, i've never actually seen it happen with playerprefs though.

If you want to test my theory then close unity and relaunch as admin

It seems like it was overwritten somewhere, when I deleted the data field it still wrote an empty one.

Thank you very much for your help, I'm debugging to see what happened.

somber nacelle
#

ah, you have an asset fucking with it. lovely

flint gull
#

One surprising thing is that there is only 1 location that calls for writing this string :))

somber nacelle
#

yeah the issue isn't where you are calling it. the issue is that the editor simply cannot write to playerprefs

#

well, either that or your asset is overwriting the values

flint gull
somber nacelle
#

i have no idea what that is supposed to mean

flint gull
somber nacelle
#

then it's probably that asset you're using that does whatever with playerprefs

flint gull
#

assetstore: advanced playerpref

lean sail
#

doesnt sound very advanced if you cant edit data

somber nacelle
# flint gull its just editor code

well i don't have access to that asset, i'm not going to buy it, so i cannot verify whether it is actually affecting it or not. you can check through the code for it or ask in whatever support space it has 🤷‍♂️

#

you can also try removing the asset from your project and see if playerprefs suddenly start working again

flint gull
#

I can delete it and test again.

lean sail
#

if it ends up being the issue, contact the dev

#

they should have some chat or way of communication on their asset store page

flint gull
flint gull
somber nacelle
#

well we don't know if that is the reason or if it is just some editor bug

flint gull
#

maybe it bug now

#

unlockBikeData 6.34545 {"data":["motorbike_07","motorbike_05"]} {"data":[]}
not by asset

#

lol, still stuck now :))

#

Do I need any permissions to override playerPref?

somber nacelle
#

did you test unity with admin privs like i suggested before?

flint gull
#

cant overide old data

somber nacelle
#

but if you don't want to test it then good luck figuring out what the issue is 🤷‍♂️

flint gull
flint gull
somber nacelle
#

well then the asset wasn't fully deleted, you have something else overwriting your playerprefs somewhere, or you have stumbled into an editor bug 🤷‍♂️
check the !logs and see if there's anything useful there (that does not mean ping me with your logs)

in what way does it "cause a bug"

flint gull
#

I'm looking into the reason behind, but just commenting that line of code, everything works normally.

#

its bullshit bug

somber nacelle
#

and you have confirmed it is caused by that by uncommenting it again and confirming that the issue happens again, right?

flint gull
#

only that line cause the bug ??

I would suggest that you debug your key values

round violet
#

is saving each animation parameter into a variable by hashing them (i dont remember if this is the correct term) really better in performance ? or just a bit ?

knotty sun
#

just a bit, it's turning a string into an int, so it will be faster but depending on usage, not a great deal

round violet
#

so it can only be better right ?

knotty sun
#

yes

#

micro optimisation

round violet
#

ok, the end of your message made me doubt

#

ty

#

also, is there any resources, website or whatever that you guys could recommend to learn "tips & tricks" in c#/unity ? (so i dont have to read the whole Unity & microsoft c#/dotnet documentation)
sometimes i do something, the randomly come across something else, making me realize that what i did was not "the best/easiest way". Practice makes you better at organizing your code, and optimizing your code, etc. But if I can save some time by knowing it before i rather take that.

There is no shortcut to experience

round violet
#

to experience no, knowledge, yes

knotty sun
#

but knowledge comes with experience, anything else is just hearsay

round violet
#

i know there is no magical book, but in other languages i came across some interesting websites or personal blog talking about interesting stuff, sometimes just curiosity and sometimes really useful to know

knotty sun
#

in my experience 90% of these kinds of sites are either out of date or just plain wrong

round violet
#

lucky that code doesnt change that much

knotty sun
#

the code may not, but the environment within which it runs changes on a second by second basis

round violet
#

but nw i see your point, i just wanted to ask anyways

#

myself when I have friends starting something in coding and they ask me some "cheat codes", usually they are asking for magical stuff

#

the famous "optimization" button for e.i.

I thought as much, not that you were an idiot but that you had duplicated keys

somber nacelle
#

so when you tested by making a new playerprefs key entry, you just used the same key you were already using instead of actually testing with a new key?

flint gull
#

Well, there were 2 duplicate keys, and I was quick to blame it on other things. What a shame.

If only you did not use playerprefs to store complex data structures all of this could be avoided 🤡
