I had a lot of messy scattered functions that I felt bad about and then just randomly realised hey all of this could be in the data class im constantly using

I think I just forgot non monobehaviour classes can still have custom functions 😭

btw personal shoutout to all the help you keep giving me @pure cliff, Really appreciate it

[worn stirrup]

this positive space issue with rigidbodies is driving me nuts

how the heck do I convert half a set of negative converting rotations to work with a postiive-only 360 area

[worldly hull]

Math.Abs?

let me see if i can work it out

[vivid raven]

alr ty

[cosmic rain]

You can represent any negative angle as positive🤷‍♂️

[worn stirrup]

I nabbed a positive clamper to help with this, but I'm still not understanding how to get what I'm looking for...

[worldly hull]

u have a spawner A that spawn coin spawner B , and then coin spawner B spawns coinA

why dont u let coin spawner B spawns the coin instead

why add a step on top of this?

[vivid raven]

the randomized spawner make 1000 instanses in a random patern in my world

[pure cliff]

btw @night harness I have a write up here you can check out that walks you through my architecture I like to use for setting up a decoupled GameState "single source of truth" system for Unity, its a quick small tutorial that demos how you can use Zenject + PropertyWatcherBase to make life easy
https://blog.technically.fun/post/unity/building-a-gamestate-with-zenject-in-unity/

[warm geyser]

Hey if anyone knows, I am trying to lerp the Color32 property of a material on a particle system and it's just seemingly doing nothing.
Code is relatively straight forward:

[pure cliff]

I think my next blog post I gotta sit down and do is a write up on how to smoothly integrate Zenject with the "new" InputSystem, including if you wanna support using multiple players

[night harness]

yooooo

good looks on the blog!

[worldly hull]

either way u dont need a second layer spawner either

[vivid raven]

why not?

[worldly hull]

if randomized spawner make 1000 random objects spawned,

just spawn the coin instead

[vivid raven]

well i want when the coin is collecnted it to respawn after a certian amt of time

[worldly hull]

1. make an array of gameobject prefab

2. use random.range to pick random object from the array

3. spawn out the object

one spawner is enough

[cosmic rain]

You're doing lerping wrong. Check the documentation on the third parameter.

[vivid raven]

im thinking since the randomized spawner works by if amt of spawned object is less then 1000 it keeps spawning, to theoretically if i delete one coin it will spawn another somewere else

[cosmic rain]

Sounds like a question for #💻┃code-beginner

[warm geyser]

I'm not lerping wrong at all, that's a technique to create a gradual interpolation using Lerp

[worldly hull]

it will work, i just think adding up a second layer of spawner with no specific reason is quite pointless

[warm geyser]

I figured out the issue, it's actually just to do with Unity's particle renderer. Even without code influencing it, I cannot change a material property on a particle system during runtime.

[leaden solstice]

• You are using Lerp wrong
• Modifying sharedMaterial wouldn't do anything when there is material or overriden with particle's property

[worldly hull]

i will work on it lol

[vivid raven]

well idk if what i just came up with will work, and i added the second layer cuz i already created the first coin spawner so i just added on to that

[warm geyser]

I've tried both, and I also don't see how I am using Lerp wrong.

[cosmic rain]

There's smoothdamp and other methods for gradual interpolation. You are using lerp wrong. It's never gonna reach the target value.

[night harness]

Speaking of lerping, what's the ideal method of using a lerp to make a number transition from a to b at a consistent rate

[worldly hull]

1. a spawner that spawns coins in RANDOM places
2. this spawner will spawn another coin once the coin is collected

right?

[cosmic rain]

Lerping is.

[pure cliff]

Lerp(a, b, deltaTime) :p

[cosmic rain]

No

don't use delta time as the third param

[vivid raven]

ye something like that. now i just gota imploment it

[pure cliff]

or wait no derp

[leaden solstice]

Your lerp is not framerate independent, and not predictable

[pure cliff]

you want uh, += delta time on some var you track

Im thinking of that other method which takes in the old val and new val out var and delta time, I forget what that one is

[warm geyser]

Lerp aside, it's not the root of my problem

[leaden solstice]

Generally you'd use particle system's option (color over time)
Or modify particle itself (via GetParticles/SetParticles)

[worldly hull]

tell me more of the respawn mechanics

1. spawner spawns x coins at first (like 10)
2. if one of the 10 coins get collected , spawn more, keep the amount at 10```
```markup
1. spawner spawns x coins at first (like 10)
2. spawns a new wave of 10 coins once all collected```

```markup
1. spawner only spawn 1 coin
2. coin is respawned once collected```

which one u want?

[warm geyser]

I'm basically trying to fade out a group of existing particles before I disable the parent game object

[vivid raven]

first one seems like what i have rn. but its a bit diffrent, when a coin gets collected it calls a function. i can make it call the function that spawns a randomized coin

[worn stirrup]

Okay so I've got it to work (will gif once I get the other arm to work and maybe fix the dang controls), but also this issue is making me clamp my angles so much, AND I had to modify it to clamp 1-360 instead of 0-359, and since this is ALL due to the fact that I'm rotating back and forth from 0, I might just make some parenting edits later to make it wiggle around 180 or something

[leaden solstice]

Or don't use _Color and use own property, that's likely the property the particle system is overriding for tinting.

[worldly hull]

ok so its first one then

[worn stirrup]

clawLeft.AddTorque(clawArmSpeed * (1 - Mathf.InverseLerp(ClampAngle(-clawLimit), ClampAngle(clawLeftGhostRot), clawLeftRot)));

Legit clamping two of the three inputs to make it all work with RB physics

[warm geyser]

I don't use SmoothDamp that often but does it work the way that Lerp technique works where it's almost a logarithmic apporach to the destination?

[leaden solstice]

I'd just use easing formula or define animation curve

[pure cliff]

If I were to tackle it in an async way Id prolly do something akin to

private async void LerpAsync(float a, float b, float duration, Action<float> callback) {
    var time = 0.0f;
    while (time < duration) {
        var lerp = Mathf.Lerp(a, b, time / duration);
        callback(lerp);
        await Awaitable.NextFrameAsync();
        time += Time.deltaTime;
    }
}

And then invoke it along the lines of:

private float SomeTrackedValue;

private void OnSomeEventOrWhatever() {
    LerpAsync(1.0f, 5.0f, 3.0f, v => SomeTrackedValue = v);
}

Can do the same thing with IEnumerator and StartCoroutine, it pretty much works the same way

[leaden solstice]

That's the point that you'd just use tween library

[pure cliff]

yeah its my understanding that lib basically has methods much akin to what I just wrote

I typically spin my stuff up myself on the fly as needed, because its usually faster than fussing with libraries if its a pretty simple implementation

[worn stirrup]

I hope wytea's still awake cuz it took forever but his idea worked lol

[prime sinew]

i dont know how to work with angles much, sorry

oh it worked?

[lean sail]

Kinda just trying to get some opinions here:
I have different scenes with some UI that can be toggled on/off, like a main menu, settings, etc. I initially wrote some basic code, script takes a button, on click set everything to inactive then set relevant ones to true but this obviously cant be reused.

Started writing some code to handle this, now my code holds a list of UIStates which is intended to be set in inspector. Each UI state has a "state" and a list of stuff it wants active but now im not sure the best way to declare what a state is, since its no longer just a premade enum. I initially stored these states as a string, but that just doesnt feel right. Should I just use scriptable objects instead of a string, so anything wanting to modify the state can just have an SO plugged in?

[worn stirrup]

So far so good! the biggest annoyance for you to keep in mind is if you're working with RigidBodies, going past 0 auto-loops to 360, so you have to have a method to clamp too big/small values into that range

And for that reason, I'd rather put a parent on the object that rotates it 180 degrees, then locally re-rotate it back up, so can use local rotation to workwithin the 180 degree 50 degree area instead of flipping between signs at 0

I'll show that when I fix it, but I'm stubborn and want this bad physics code to work first

Then I'll fix it 😛

[cosmic rain]

Yeah, sounds like SO is the way. The approach does sound a bit weird to me.
Why not just handle it on the level of UIWindows and UIManager? The UIManager would hold references to all the windows and when one window is opened, others should close or something like that?

[worn stirrup]

nvm this clamp code officially don't work for the other arm

[lean sail]

the naive approach i wrote before is like basically hardcode
https://gdl.space/yubapuboni.cs
Its not much UI really that im toggling because Im just setting a parent active/inactive. but i still need some way to indicate which one to set active if im trying to create a script I can reuse

[worn stirrup]

ugh uguu errored so here goes gfycat

10 years later....

[vivid raven]

oh i already figured it out, i just need to switch what object the randomizer spawns, sorry for making u do all this work

[cosmic rain]

Do you plan to have so many different menues that hardcoding them is not an option?

[worldly hull]

randomrange handles all the work

[lean sail]

not really, i think right now its like 5. I am also really considering leave it as the hardcode option because I dont want to overengineer. I was just considering this too incase I want to reuse this script in future games

[vivid raven]

reading over what u made that 100 times more complicated then what i can come up with, but ty for helping with the idea of respawning the coins, i even think its more intresting cuz you cant afk in that one spot waiting for a coin to respawn

[worn stirrup]

good god

direct link isn't good for streamable

let's try once more lmao

[cosmic rain]

I think the issue is probably with you mixing up UI windows and game screens. For example, a lobby menu should be a separate screen with it's own unique ui windows and ui management. While friendsListUI should probably be a window that can exist in a certain(or several) screen. When switching between screens, you would disable other screens and consequently the ui windows that belong to it, while enabling the new screen with it's windows. While in a certain screen, different windows belonging to it, can be toggled on and off.

[worn stirrup]

@prime sinew finally, inverselerp in action! https://streamable.com/62puia

The right one doesn't work, time for an hour of fixing

[cosmic rain]

And then you can expand on it by nesting windows in windows to make sort of an hierarchy. So when you disable a parent window, everything below it would disable as well.

[prime sinew]

is there a reason for it to be physics based?

and can the claw be asked to close midway of closing

or is it always the full range of motion

it looks cool btw

[worn stirrup]

I am obsessed with physics games, I'm making a space game about pulling objects out of orbit, with different weights, sizes, so hooking an only-so-heavy crane around and yanking them out of orbit is kinda the idea

[prime sinew]

sounds fun

[worn stirrup]

making/doing the trash was the fun part, if I started with the crane I would've given up xD

https://streamable.com/evc1ul

none of these textures are mine, but this is a prototype

[lean sail]

im unsure what you mean with different screens, right now this script is just in its own scene and theres only really 4 objects that im toggling on/off. The objects are also parents of some UI, so InLobbyMenu is a parent object that contains children of a button, labels, and will contain the list of current players.
I realize I also dont even need to include the friendsListUI since its toggled in both states

I feel thats somewhat similar to what youve described, but if i treat being in a lobby and outside a lobby as different windows entirely, wouldnt that just mean I need to duplicate things that exist on both

[cosmic rain]

Okay. I guess I made some assumptions that were not actually true.
By different screens, I assumed that you have like a log in screen, in game ui screen, shop ui screen, etc. Kind of separate ui spaces if that makes sense.

As of now I don't see much point in a complex system. Just hardcoding stuff is good enough. Later, when if you feel like you're starting to write repetitive code, you might want to consider refactoring things - pulling members from your existing ui script into a base class and extending it for different screens.

[cosmic rain]

You can keep several "root" ui objects that exist(or a re persisted between) in several screens/situations so that you don't need to duplicate them.

[lean sail]

Yea ill just stick to this easy method then, i was kinda reluctant with SO as states because it also just feels weird

[lean sail]

i probably could have described this better to avoid that confusion, thanks still

[night harness]

@lean sail I think last time I wanted to do this but not spend too much time on it I did something super yucky like this

dunno if it helps at all, just a psycho take

[lean sail]

I personally wouldnt go with a disableList, I just disable everything. If its not in the enable list, its not enabled

[night harness]

Fair, depending on some situations you might want the ability to specify but def. not necessary

[lean sail]

well im no longer going with this solution but what I did was this on start

        // Get all unique elements to avoid setActive repetition
        foreach (var uiElement in uiStates)
        {
            foreach (var element in uiElement.activeUIElements)
            {
                if (!allUIObjects.Contains(element))
                {
                    allUIObjects.Add(element);
                }
            }
        }

so it only disables things already "registered" in a UI state. Not like everything on the canvas

[worn stirrup]

bruh why it takin 20 sec to complete domain with 4 scripts

is it the mobile SKDs e.e

the 180 thing was easier than I thought, now it's just on to arm 2 again

[night harness]

make sure your unity projects are ignored by windows defender and look into disabling domain and scene reloading and see if your able to use it

[worn stirrup]

wait you can disable domain reloading

thank you

[night harness]

In Project Settings -> Editor.

Read up on the settings though because they do cause problems with certain things

Enter Play Mode Settings needs to be ticked for the other two to have control, so having the latter two be false disables the reloading

[valid raven]

Asking for help from an amateur dev here-

I just started learning how to code and bought few templates to help me get jumpstart with prefabs and all. Been learning how to set up PlayerMovement since last couple of days. My issue since lately is the code I am following and learning
from had vanish or disappear for "death" while I had body dies lie there and set as static, but it can still flip x going left or right while lying there static. Kept getting error message which is because of the dead body moving left and right, assuming. If anyone knows what's the code to add or suggest would be greatly appreciated.

Oh to clarify, I am doing 2d platform game

[prime sinew]

Hey, before going further, you should configure your IDE

!vs

[tawny elk]

Visual Studio guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

[prime sinew]

You set your rigidbody to static when it dies, but you still are setting it's velocity which you shouldnt because static rigidbodies don't move. That's what the error is complaining about

[valid raven]

Yeah

and I have visual studio no?

[prime sinew]

The issue is, in your Update where you set the velocity, you don't have a check to see if you're dead

[night harness]

the cool stuff isn't working as it should

[prime sinew]

I didn't ask you to install visual studio, the message asks you to configure it

It doesn't recognize Unity properties

[night harness]

Also worth dropping the bot message about sharing code too (i dont know the command)

[valid raven]

oh ok so i need to download it on unity to have it connected simultaneously?

[prime sinew]

It's almost Microsoft word at the moment

No

[valid raven]

I thought they were already, ok

[prime sinew]

Please

Click the link

It'll walk you through how to configure

Either way I've pointed out your possible issue

Probably need a boolean that is set when you die

Then your Update can check that boolean before attempting to set the velocity

[valid raven]

ok thank u

[prime sinew]

I just stress that having a configured IDE is a requirement to get help here, simply for the sheer amount of silly mistakes it prevents

[valid raven]

sounds good

[night harness]

Your question was well typed btw, good amount of information. a lot of people struggle with that

[prime sinew]

yep, supplying the error message and the code is appreciated. in the future, do follow this guide on how to share code though

[mighty yew]

I'm not really sure if this is possible or not, but I want to "replace" certain animations with other animations in my animator through code. Like normally its animation one, but when an event happens it becomes animation two? both animations will function nearly identically and will just look different. Is there any way to do this?

[night harness]

Nah your doing fine homie. Just once you get your visual studio hooked up nice and know how to share code nicely it's like 100x easier for people to help you out

[prime sinew]

It's alright. Feel free to check the pins in #💻┃code-beginner for some useful resources too

[worn stirrup]

Try looking into replacing the animationClip within the animator, maybe?

[valid raven]

I mean I already had visual studio and unity on and all.

[mighty yew]

which component is animationClip?

the actual animation gotcha

[worn stirrup]

My bad, it's something you can program with

[mighty yew]

no you're fine it was my misunderstanding

[prime sinew]

awesome!

[prime sinew]

the point i was making is configuring your visual studio to work with Unity

if done correctly, it'll be underlining errors and autosuggesting properties

@valid raven

best of luck

[valid raven]

ok so i checked, I already had it installed in unity and all

[prime sinew]

can you show a screenshot of your IDE then?

the point wasn't to have it installed in Unity. it's not even installed in unity. it's a separate program that can be configured to work with Unity

[valid raven]

where do I find IDE?

[prime sinew]

your IDE is your visual studio

IDE is the program you use to write code in

[valid raven]

ok it's in 2nd image that I posted earlier?

[prime sinew]

i want to see the current state

to see if it's configured

which is the entire point of this convo

[valid raven]

is this ide?

[prime sinew]

yep

looks good. it's configured now

now when you type, you'll see the red underlines if there are errors

and it'll suggest unity stuff for you

[valid raven]

ok i tested again, still have an issue, it's the velocity that says i m not supposed to be flipping when i m in static phase (dead)

so i m trying to figure out if it's a new code to add in playerlife script or fix somewhere in movement like disable movement while dead?

[prime sinew]

i already told you

[valid raven]

like die = movementstate = false?

[prime sinew]

#archived-code-general message
#archived-code-general message

you need to set a isDead boolean to true when it dies, and only set the velocity if the boolean is false

[valid raven]

thank you

[valid raven]

https://gdl.space/raw/pudayefedo

does that work better? still cannot figure out the correct code to it @prime sinew

I added "bool _active = true" then last 3 with this-

private void Die()
{
rb.bodyType = RigidbodyType2D.Static;
anim.SetTrigger("death");
_active = false;

thoughts?

no errors in visual but still same issue in unity

regarding static body that is

trying to figure out how to make _active works itself without rigidbody to static

[prime sinew]

Okay. So you set a bool to false

Where did you use it to make sure velocity is only set when it's true

[ebon panther]

hi so I've been using this basic coding site called "scratch" for a while, any good ways to transition from scratch to unity?

[prime sinew]

You just need an if statement around the code that sets velocity in Update

If you don't understand that, please, you would benefit from the beginner stuff in Unity Learn

And an introduction to c# tutorial

find the line that sets velocity

then wrap that in an if statement that makes it so that it'll only run the velocity setting line if your _active is not false

since you set it to false when it's dead, and you don't want it to set velocity when it's dead

[unique robin]

There is something wrong with my Input detection. I have done lots of debugging and the input is the direct problem. I am aware FixedUpdate can't detect GetKeyDown and GetKeyUp however if i call for GetKeyUp in an update method, set a variable for true if so, and then set that variable to false after uisng it in FixedUpdate, the input should register. However litterily a basic GetKeyUp or even GetAxis doesn't work in the update method

[elfin quest]

I gues, can we see code?

[unique robin]

Wait I wills et up example script and see what happens

[warm night]

Hey, I'm a beginner at Unity Netcode (btw i didn't see any channels for that so thats why i'm posting this right there), I want to have a GameObject (or a transform, or even a script, idc) to pass a gameobject through a clientRpc method, is that possible? because i got some errors that gameobject cannot be passed through clientRpc methods :/

[unique robin]

using System.Collections;

using UnityEngine;

public class Script : MonoBehaviour {

}

I will spam w or up arrow and nothing is in concole

[elfin quest]

I've invited u to the netcode server but no, you can not pass gameObjects. What you can do is get the NetworkObjectId from the NetworkObject component and pass that (it's a ulong) through an RPC. Then on the reciving RPC you can grab the gameObject with:

GameObject object = NetworkManager.Singleton.SpawnManager.SpawnedObjects[NetweorkObjectId].gameObject;

[warm night]

oh, okk, i saw the invite, but ok thanks i'll search with this

[prime sinew]

[prime sinew]

is this attached to an object

[elfin quest]

It's working for me. Mayb check the inputs in the projects settings. If not I don't think it's a code problem. Maybe someone at #🖱️┃input-system can help you out.

[unique robin]

Yes

[prime sinew]

are there compiler errors @unique robin

[warm night]

maybe in player prefs ?

[unique robin]

No, I would think It is in ainput error

[warm night]

like the basic input

or the qwerty keyboard, i already had this problem

[unique robin]

This is kind of related to #🖱️┃input-system but if I have a verticle axis does that get rid of all kets attatched tot hat axis for GetKey

[prime sinew]

are you using the new input system, or the old input manager

you should clarify that

@unique robin

[unique robin]

I am not sure haven't uopdated in a while

[prime sinew]

find out

google how to find out what you're using in your project

[unique robin]

I am pretty sure I am using new input system

[prime sinew]

did you check?

[unique robin]

using unity 2021.3.5f

[prime sinew]

that does not matter

your unity version does not matter. it's what your project is set up to use

if you are using the new input system,
https://www.youtube.com/watch?v=0z-6lxL_sS4

[unique robin]

I often use the old input system so potentially I'm not using the new input system and trying to use the old

[prime sinew]

Check what you're using now

Is the object this script is on active

If you debug log in the update, outside the if statement, does it print

https://gamedevbeginner.com/input-in-unity-made-easy-complete-guide-to-the-new-system/#:~:text=If you want to be sure of which input system you’re using%2C go to Edit > Project Settings then Player > Other Settings and look for the ‘Active Input Handling’ setting.

[unique robin]

yes

[scarlet viper]

ComputePenetratoin - if the output distance variable is above 0.0f then there was no penetration ?

[late lion]

The distance is always positive. It's the distance the first collider must travel along the direction to separate from the second collider.

The method returns a bool for whether there is any penetration. If it's false, then direction and distance are not defined, but probably both zero.

[scarlet viper]

it works now thanks

[keen solstice]

So I made a sprite library. Why am I unable to add it to the gameobject Sprite renderer and the animation timeline?

Following this portion of the manual BTW.

https://docs.unity.cn/Packages/com.unity.2d.animation@6.0/manual/FFanimation.html

[hexed geode]

what i want to do is to instantiate a series of gameobjects which have buttons in their children objects, and then make them call a function on click which will have a parameter based on their order:

private void Start()
    {
        for (int i = 0; i < SkinInfoHolder.instance.skins.Length; i++)
        {
            GameObject createdSkin = Instantiate(skinPrefab, grid);
            createdSkin.GetComponent<Image>().sprite = SkinInfoHolder.instance.skins[i];
            createdSkin.GetComponentInChildren<Button>().onClick.AddListener(delegate { PickSkin(i); });
            buttons.Add(createdSkin.GetComponentInChildren<Button>());
        }
        UpdateButtons();
    }

what happens, is that the gameobjects and the buttons do get created and added to the list, but they don't do anything on click. i tried doing createdSkin.GetComponentInChildren<Button>().onClick.AddListener(() => PickSkin(i)); as well, but that didn't work either. am i doing something wrong?

[leaden ice]

well I do see one bug here

which is the classic lambda variable capture bug in a loop

you need to do this:

int localI = i;
createdSkin.GetComponentInChildren<Button>().onClick.AddListener(() => PickSkin(localI));```

otherwise all of the buttons will reference the actual i variable which by the end of the loop will == SkinInfoHolder.instance.skins.Length

[hexed geode]

ok damn that is very weird, it doesn't show anything in the inspector, but it works as perfectly as it can???
thank you very much either way, but that confuses me

[leaden ice]

This is expected

listeners added with AddListener don't show in the inspector

[hexed geode]

oh, i see

havent worked with listeners basically ever, never knew that, thank you!

[leaden ice]

The only way to add the inspector ones is with this: https://docs.unity3d.com/ScriptReference/Events.UnityEventTools.AddPersistentListener.html

I was making a character creation screen, I can chose between female/male at the moment but in a later fase I want to add stuff like races, hairstyles, haircolour, skincolour. Someone told me to put them in variables and use playerpref to save those variables. For example, male and female would be at the top. if you press male, you get for example "int gender = 1", then you could go to races and click the race "human" you'll get a male human, if you click elf, you'll get a male elf and so on. For hairstyles then for example, if you picked male gender (1) and human race (1) you'll only get the hairstyles for that specific number (1,1). let's say you picked male gender but for example demon race (int 4 as example so you'll get, 1,4) you'll get hairstyles for that specific gender and race like horns, and so on

Another guy told me to make classes in unity for each variable. but I guess all classes also use an numeric index so it works the same but different?

Is there anyone who's willing to put me in the right direction, maybe with an example script or something? I think I can script the first way myself, with a bit of thinking, I just don't know if its the right way to do it. I don't know much about the classes system tho.

[west sparrow]

I'd probably use an Enum for the types, I.e. character classes.

public enum CharClass {
  None,
  Warrior,
  Archer
};

Then a base data type, could be an SO.

public class CharClassElement {
  public CharClass = CharClass.None;
  public int Power = 10;
  ...
}

Then from there, either use the generic as a base data type or use inheritance for class specific code. You shouldn't really need to do that for base stats or base character design though.

[mellow vapor]

what .net sdk should I download?

[west sparrow]

But an enum is essentially an int with a human readable name.

[austere oriole]

https://hatebin.com/jmjyqdlbpt

Something like this by any chance?

[west sparrow]

That would work!

[austere oriole]

I have a second script for customizing the character, but it also needs to be saved when everything is picked

https://hatebin.com/omsjrhyqwy

But I don't really get the classes, how do I save the different hairstyle assets to it for example :c

How do I even get the hairstyles to fit on the head where they are supposed to be and how do I save everything so that the player go's into the game with the customised character and keeps it when loading the save file again

:p scripting is hard

[rancid jolt]

I want the cursor to be invisible on a particular scene. But it is getting invisible only if I lock the cursor state which I can't do because of the nature of the gameplay. Is there a way to do it without locking the cursor?

how come is it not assigned after i log its item count?

[late lion]

You might have two instances of GameManager, one with it assigned and logging correctly, and the other with it unassigned and failing to log the count.

[candid kiln]

no more logs, i'm pretty sure there is only one instance

[late lion]

Which line are you getting the exception? And why does it appear as a regular log message in your console and not an error?

[candid kiln]

264

[leaden ice]

that says 624

not 264

and it's likely the line of the Debug.Log in your catch block

[candid kiln]

what

[leaden ice]

anyway - it's pretty clear blockSprites is not assigned

[devout harness]

I noticed accessing the rotation.eulerAngles.x of a transform returns strange results. I'm getting something like:

[candid kiln]

it logs the item count in list

not the line of error

[leaden ice]

you cannot read a single euler angle in isolation and expect sane results. Euler angles are intricately tied to the other angles in the set due to gimbal lock

[leaden ice]

where are you getting the line number of the error from then

[leaden ice]

that says 265 now

[candid kiln]

because i've added a line to log something else

it's the same line

[leaden ice]

one issue here is your use of the ?? operator

that doesn't work properly with Unity objects like Texture2D

[candid kiln]

hold up

lemme try something

[rancid jolt]

It is already in the code snippet I provided.

[devout harness]

Hmmmm, how can I go about reading the rotation for a transform then? I'm trying to make a camera look script, in which I want to check the current rotation to avoid looking beyond straight up/below straight down (to stop the user from snapping their neck to look behind themselves)

[knotty sun]

yes, but did you notice in their example they do not lock the cursor?

[leaden ice]

you should track the pitch of the camera in your own float variable and clamp that

or use Vector3.SignedAngle to get the proper angle

[candid kiln]

this got it fixed, thank you @leaden ice

[devout harness]

Ahhh okay, then just assign the camera to a new rotation each time (based off the current up/down look angle float)

[rancid jolt]

Yes, I am also not locking the cursor, It works when I am locking it but I don't want to. I have just confined it for game reasons, now I remove the confinement as well.

[devout harness]

That worked beautifully, thank you!

[rocky helm]

How should one approach making an NPC script which, in a nutshell just wanders around and runs from the player when the player is holding a gun? I've tried making something like this that I could build up on two times now, but both have come out pretty ugly and hard to use.

[dawn mauve]

Finite state machines are worth looking into. They’re relatively easy to implement.

If you wanted something more complex look into behavior trees

[dawn mauve]

https://github.com/ashblue/fluid-state-machine

Here is a library if you just want to get started. Ashblue is amazing. He also has a behavior tree library in case you wanted to go that route.

Though for your simple AI I’d stick with FSMs

[hard viper]

I have a SO for entityData that tells a given gameobject what sorts of things it should be vulnerable to (ie fire, spikes, stomp, etc).
I want to be able to keep something mutable during runtime so that the vulnerability of an individual gameobject might change during runtime (eg Koopa shell does dmg to player when in a moving state, and not when stationary).

Differences during runtime might be very small. Does anyone have a suggestion for how to handle this with minimal code repetition?

i feel like there is going to be a good design pattern for this.

[knotty sun]

https://assetstore.unity.com/packages/tools/utilities/scriptableobject-pro-218340

Mutable ScriptableObjects at runtime

[leaden ice]

one option is:

public MyScriptableObject mySo;

void Awake() {
  mySo = Instantiate(mySo); // now it's a runtime local copy that you can freely modify
}```

[hard viper]

i see. and I would need to use reflection to make a deep copy? which I assume is what steve’s package does automatically?

[heady iris]

I prefer to just keep the SO immutable

and to track any modifications to that base state separately

[leaden ice]

How deep of a copy do you need?

[heady iris]

Alternatively, the SO is just used to construct the runtime data

I would do the former if I was clearly just making additions to the base state

and the latter if the fundamental properties were changing

[hard viper]

i do not know yet. I would start by assuming a complete deep copy. everything in it should be value type. ints, bools, enums, and a couple of strings

[heady iris]

"Deep copy" means that references are also recursively copied

[hard viper]

changes are only applied to an instance, so I want to keep the original under lock and key

[heady iris]

from my experience, when you ask about how to do a "deep copy", you're doing something the hard way

[hard viper]

there are no references in this SO

only value types

[leaden ice]

if this is already the case then Instantiate is a "deep copy"

[hard viper]

i see. would it automatically get destroyed/garbagecollected when done?

[heady iris]

as always

[leaden ice]

No, you will need to call Destroy on it

[heady iris]

oh right, yes

[leaden ice]

in OnDestroy

[heady iris]

after you destroy it

i forgor

[leaden ice]

Since it's a UnityEngine.Object

[heady iris]

It wouldn't die during a scene switch, right?

[hard viper]

this feels a bit dangerous, but I can handle that. I mostly want there to be zero chance of ever modifying the original

[heady iris]

since it's not part of a scene

[hard viper]

maybe I should make a childclass of my SO to avoid getting tripped up?

[heady iris]

that is one option

Copy<T> where T : ScriptableObject

[hard viper]

like EntityData: SO, RuntimeEntityData : EntityData.
RuntimeEntity data is mostly an empty class

[heady iris]

it'd have a constructor that takes a T and instantiates it

[hard viper]

hmm, maybe I should look into stevie’s package.

[knotty sun]

May I DM you

[hard viper]

ok

i gtg in 3 min tho

[primal wind]

Can you not cast an UnityEngine.Object to Sprite?

I'm doing that but it just fails

[knotty sun]

Object as Unity.Object or System.object?

[primal wind]

Corrected

Unity ones

[knotty sun]

No, Sprite is not a UnityEngine.Object

[primal wind]

Oh

Well back to the drawing board

[knotty sun]

use System.object, will work

object o;
Sprite sprite;
if (o is Sprite) sprite = (Sprite)o;

[leaden ice]

Should be able to. Not sure what Steve is talking about:
https://docs.unity3d.com/ScriptReference/Sprite.html

Can you explain what you mean by "it just fails"?

[primal wind]

I think it actually is a Texture2D

i'm gonna test that

[leaden ice]

If your object is not actually a Sprite then it will fail

[leaden ice]

you can just do print(myObject.GetType().Name)

[primal wind]

yup it was a Texture2D

Now it works

[knotty sun]

which you are trying to make a Sprite from?

[leaden ice]

if you need a sprite from a Texture2D you would use https://docs.unity3d.com/ScriptReference/Sprite.Create.html

[primal wind]

I did

I was trying to assign it to an Image directly out of the method that casted it

Now it works

[leaden ice]

not sure I totally follow but, glad it's working 👍

[knotty sun]

if it's similar to the problem I recently encountered, Sprites are not included in the AssetDataBase but the Textures they are created from are

[primal wind]

I guess it would work if i make a Sprite field and put it there but that would make my thing a bit less unified

I don't even know if what i did is useful

[sudden meadow]

Any idea why this is all of a sudden causing Unity to take 5 minutes to reload script assemblies?? I haven't even changed this today and it was working up until now when it started acting up out of the blue.

I tried changing only LoT_Animation to Serializable but it still happens.

Do I have to switch to serializefield or something

[late lion]

Can you check what is getting serialized in the yaml? It seems like it's serializing the sprite in place, like it doesn't have an asset it can reference by GUID.

[sudden meadow]

@late lion sorry I dont know what the yaml means or how to check this

[knotty sun]

To start with Lot_AnimationFrame does not have a parameterless constructor, that is going to upset serialization/deserialization

[hard viper]

I’m thinking more about this. My SO has every field with public get, private set (so it doesn’t accidentally get altered), but I then want my copy to be mutable.
Would it be best to make them protected setters, and use a child class where everything is public?
And child class uses reflection to make a copy of the original fields into itself. I think this is right, but I want to ask before granting write access when readonly files are involved.

[sudden meadow]

@knotty sun oh ok I see. I'll try that.

Doesn't seem to make much of a difference. Actually hold on

[late lion]

If this is getting saved as part of a scene, you can open the .unity scene file in Notepad to inspect the yaml and find your variables, like "animationSequence". Or if it's saved in a prefab, you can open the .prefab file instead.

[sudden meadow]

Wait on the AnimationFrame? But it's a struct and can't have a parameterless constructor. Maybe I should just make it a class

It's saved in a scriptableobject

perhaps i can open that like a prefab

[late lion]

Yes, you can open the .asset as a text file through any text editor, like Notepad.

Assuming you have text serialization enabled instead of binary.

[leaden ice]

there's no need to use any reflection in such a setup

you can mark the fields as protected

[hard viper]

but then how would I allow other classes to modify the child

but not the original

[leaden ice]

through public properties on the child

[hard viper]

in that case, I need to maintain it so whenever I add fields to the original, I also need to add fields to the child

[leaden ice]

you can also turn this whole thing around - you can make an interface like ReadOnlyThing which only exposes getters and not setters

then you don't need a child class

pass the SO around as that interface in places where it shouldn't be mutable

[dire crown]

That's what I do as well

Interfaces 👍

[sudden meadow]

I don't really know what to make of this, nor do I understand why it's talking about Seralization depth just because I have a sprite field tbh.

I am simply storing sprite references in scriptableobjects

[hard viper]

if the original is in a class with public setters, then I am at risk of forgetting, accessing it through not the interface, and changing the original

[sudden meadow]

if i don't serialize i can't see it in the inspector

[late lion]

And they are definitely assets and not runtime generated sprites?

[sudden meadow]

yeah

[knotty sun]

Maybe silly question but have you defined your own Sprite class?

[sudden meadow]

I haven't no

[late lion]

I don't recognize this "length: n" under each sprite. I don't have that in my own scriptable objects that are serializing sprites.

[knotty sun]

its part of his struct

[late lion]

Oh, my bad

[sudden meadow]

yeah it's just an int in the struct

[knotty sun]

can you screenshot the inspector for the SO

[sudden meadow]

yes just give me 5 minutes for the rebuild to finish timing out

[knotty sun]

lol

in the meantime, which Unity version?

[sudden meadow]

2021.3.24f1

and as I said it was working fine until just now, and I haven't changed this class today. So I might go back and try reverting some stuff I guess if all else fails.

[lone dawn]

So I made a moving platform script that uses transform.SetParent on the character controller.
It works but only manually? Like when I change the position of the platform with code it slides below the player, but when I manually change the location in the editor it works? Any help?

[late lion]

I don't see any problems with the code. This might be some weird Unity bug that will require nuking the Library folder to fix.

[heady iris]

character controllers get mad when parented, don't they

[sudden meadow]

I could try nuking the library folder

[heady iris]

I would do that

especially if you've ever force-closed the editor

you can get some Weird Cruft in there that makes the editor misbehave

[heady iris]

random errors that make no sense

[sudden meadow]

this is the SO

[knotty sun]

nothing wrong with that or the YAML file as far as I can see

[lone dawn]

Character controllers get mad period lol

[heady iris]

i suspect that unity is unable to update the .asset file because of the serialization depth limit

so we aren't seeing the actual problem

I see no reason for this to happen, so i'm blaming library demons

[knotty sun]

but why, this is the kind of stupidity I would expect from 2022 not 2021

[heady iris]

we're brushing up against one of the two hard problems of computer science: cache invalidation

[sudden meadow]

https://gdl.space/divihuseba.cs idk if this works. you are missing the scriptableobject tho so idk if you can make much use of this.

rebuilding the library now i'll get back to you

[knotty sun]

Thats perfect, I can make my own SO

[sudden meadow]

It seems to work fine now

Not complaining about the serialization depth either

so I guess it was a library quirk

[late lion]

Maybe you accidentally made a circular reference in LoT_Animation for long enough to cause a recompile and mess up the cache.

I would have expected that Unity can recover from that, but 🤷‍♂️

[sudden meadow]

Well, it seems fine now so thanks for the help 😄 Ping me if you want any follow up info, otherwise I guess I'll be back of it comes back soon lol.

[knotty sun]

@sudden meadow Works for me so i guess it was just a wierd bug

[sudden meadow]

Yeah seems like

[heady iris]

I need to dig into how that kind of corruption actually works at some point

but at a high level, the Library is just a gigantic cache

all kinds of stuff generated from your Assets (and from packages)

i suspect that crashes or freezes that end with a SIGKILL can leave it in an inconsistent state

unity doesn't understand that it needs to regenerate that data, but the data is bogus

also, augh

Message: Build asset version error: assets/scripts/monobehaviours/debug.cs in SourceAssetDB has modification time of '2023-08-15T16:07:46Z' while content on disk has modification time of '2023-08-15T16:08:15Z'

go away

[indigo arrow]

I'm having a weird issue where my bullet prefab is colliding with the environment, but these collisions aren't being detected by its script:

using System.Collections.Generic;
using UnityEngine;

public class EnemyBullet : MonoBehaviour
{
    float bulletForce = 12f;
    float bulletLife = 2f;
    AudioSource source;
    public AudioClip bulletCastSound;
    public AudioClip bulletImpactSound; 
    public int bulletDamage = 1;
    public float bulletKnockback = 7;
    float currentBulletLife;
    Rigidbody2D bulletRb;
    void Start()
    {
        bulletRb = GetComponent<Rigidbody2D>();
        source = GameObject.FindWithTag("GameManager").GetComponent<AudioSource>();
        source.PlayOneShot(bulletCastSound);
        currentBulletLife = bulletLife;

        bulletRb.AddForce(transform.up * bulletForce, ForceMode2D.Impulse);
    }

    void Update()
    {
        if(currentBulletLife <= 0)
            Destroy(gameObject);
        else
            currentBulletLife -= Time.deltaTime;
    }

    void OnColliderEnter2D(Collision2D other)
    {
        print("Enemy bullet hit");
        source.PlayOneShot(bulletImpactSound);

        bulletRb.velocity = Vector2.zero;
        LeanTween.scale(gameObject, new Vector3(0.001f, 0.001f, 0.001f), .5f)
        .setEase(LeanTweenType.easeOutExpo)
        .setOnComplete(() => {
            Destroy(gameObject);
        });
    }
}```

am i missing something obvious

[robust dome]

@indigo arrow probably the collision is taking place and it is too short to be detected means the bullet might be traveling too fast

i also see an error in your code

[indigo arrow]

but its not phasing through objects like it would if it were travelling too fast

[robust dome]

void OnCollisionEnter2D(Collision2D col)
{
Debug.Log("OnCollisionEnter2D");
}

it should look like this

you should always let intellisense do the work for you to prevent such mistakes, it seems like you typed it manually

[indigo arrow]

but i have this on my player script:

    {
        if(col.gameObject.CompareTag("Enemy") && currentISecs <= 0)
            TakeDamage(col.gameObject.GetComponent<Enemy>().enemyDamage, col.gameObject.GetComponent<Enemy>().enemyKnockback, col.transform, false);
        else if(col.gameObject.CompareTag("EnemyBullet") && currentISecs <= 0)
            TakeDamage(col.gameObject.GetComponent<EnemyBullet>().bulletDamage, col.gameObject.GetComponent<EnemyBullet>().bulletKnockback, col.transform, true);
    }```

and that works fine

[robust dome]

yeah but look at the difference

you have OnColliderEnter not OnCollisionEnter

[indigo arrow]

ooh

my bad

[robust dome]

intellisense use it ;D

[indigo arrow]

i misread yours as (Collider2D) rather than (Collision2D)

thought that was the difference

[indigo arrow]

thank you

works now

[topaz ocean]

how do I access the colors in project preferences from script

[leaden ice]

which colors specifically?

like the editor theme colors?

[topaz ocean]

Im specifically going for axis colors

these

[leaden ice]

This perhaps? https://docs.unity3d.com/ScriptReference/Handles-xAxisColor.html

I've never tested if that actually changes with the editor settings

but I imagine it does?

[topaz ocean]

seems to work, im not trying to change them, just use them for drawing debug stuff

[muted vigil]

How do people structure flexible power ups?
My approach was for each thing to have a list of power ups where they can "hook" into points where systems interact. Below I have a couple spots set up so for when anything would take damage or deal damage it would loop over its power ups and pass the data for each one. Is this how people normally handle it?

public class Powerup: ScriptableObject
{
    protected PowerupAble PowerupAble;
    public Powerup(PowerupAble powerupAble)
    {
        PowerupAble = powerupAble;
    }
    
    public virtual  void Setup()
    {
        
    }

    // Update is called once per frame
    public virtual void Tick(float timestep)
    {
                
    }

    public virtual void OnDamageTaken(Damage damage)
    {

    }

    public virtual void OnDamageDealt(Damage damage) { 
    
    }

    public virtual void OnMovement(float speed)
    {

    }
}

[rigid island]

I would use scriptable objects

[muted vigil]

updated above. so that would be a scriptable object where each power up would inherit from, so would the solution of providing a bunch of "hooks" where the power up can listen for when it is applicable seem reasonable?

[west lotus]

This is a pretty decent implementation that I have used before https://www.jonathanyu.xyz/2016/12/30/buff-system-with-scriptable-objects-for-unity/

[pure cliff]

it would loop over its power ups and pass the data for each one
What do you mean here, on this part?

[muted vigil]

so say the player has a damage power up to do 15% more damage. When the player's weapon hits before the damage gets applied, that damage would be passed to each function in a list and the final damage returned would actually be used and then that damage would be ran through the powerups OnDamageTaken for what is being damaged.

[pure cliff]

1. Do these powerups need to "Stack" with themselves, IE can you have for some buffs 3 copies ("Stacks") of the same buff?
2. Do they have expirations, and do you want/need to track the expirations individually
3. If you answered yes to both above, do you also need to track the expirations individually for each individual stack of the same buff?

[leaden ice]

I usually make a class like "ModifiableQuantity" which can take additive and multiplicative modifiers. I use that as the "damage" variable on my abilities. The powerups then just act as a modifier on that ModifiableQuantity. In general the value is mostly cached and only computed when adding/removing modifiers

[heady iris]

yep, that's the deal

[muted vigil]

Not originally planned. The idea was random where they could "stack" and I was just going to treat it as having 3 instance say of the same power up. Yeah my idea for anything expiration based would be on the Tick function would let it do its countdown there and self remove.

How would you handle more complex scenarios? Say Like on successive hits you get a stacking modifier for that buff but if you miss it drops off or say you get a power up that has a modifier for how far you are from the target you hit?

[muted vigil]

I do like this for like an RPG style game with more static modifiers but these are meant to have high impact and I also plan on them being able to interact further out. say spawn a gameobject on the player for a visual buff and let the Powerup handle when it shows/what it shows.

[pure cliff]

each of your "types" of distinct buffs needs to have its own unique identifier, Guid or whatever.

I would likely have a some form of "subscribe" and "unsubscribe" method on something I would call a BuffContext or... something like that. When the player's stats change so that they gain or lose the capability of a buff, I would call up that respective Buffcontext and fire off its subscribe or unsubscribe.

So for example lets say you can get FooStacks from the FooAbility. When the player equips the item that grants them the FooAbility, it would have a list of associated BuffContexts that need to fire off their Subscribe methods, because they now have stuff they need to watch for.

So your FooStackContext would add a subscription to listen for, specifically, the "Attacked" event, and it would get the attack data, and it would then decide if it adds new FooStacks, or remove em all based on your example.

When you equip the item you fire off FooStackContext.Subscribe method, and when you unequip you fire off the FooStackContext.Unsubscribe

The buffs themselves would likely just be a Dictionary<Guid, PriorityQueue<float>> sorted such that the "first" item to be dequeued is the one with the lowest duration.

And on your "ticks" you just decrement all the values in the queue, and if they are still a positive value you re-add em to the queue for next tick.

[muted vigil]

ah I see so youre saying change it from the Powerup having all of these virtual functions and just slim it down so that the Powerup gets a context of all the things it can interact with weapons,health, movement etc and then subscribe to events and do something like this https://stackoverflow.com/questions/1446256/pass-a-return-value-back-through-an-eventhandler to let whatever emitted the event get the final result of modifers and then do whatever. Yeah that definitely seems more flexible.

[swift falcon]

I'm trying to modify a Texture2D's Multi-Sprites to contain all the sprites parsed by an Adobe Animate XML parser also written by me, however I'm currently experiencing the issue that my code places the SpriteRects inverted vertically (as can be seen in the attached photo).

I have tried different versions of subtractions and additions to attempt to fix it, but the issue still persists, all other combinations making it worse.

This is my current code that causes the attached issue: https://hastebin.com/share/sonokalubi.cs, any help is appreciated!

[mighty yew]

Creating a combat system, and a big part of it is the modularity of actions in the game. For example you can replace your attack 1 with a different attack2 in order to adapt to the situation. To code attacks I have an "attack" class that i plan on being the parent to all the other attacks. Issue is, in the child attacks I cant declare values to variables that have changed. Ie:

public class Attack{
  public int damage:
}
public class DiffAttack : Attack{
  damage = 3 //doesnt work
}

not sure how to fix this

But also, is this even the way i should be going at it? Is there a better way to do this?

[knotty sun]

public class DiffAttack : Attack{
public DiffAttack() {
  damage = 3; // will work
}
}

will work

[mighty yew]

cool! thanks! (how did you color the code in c#)

I'm trying to get a UI (using canvas) to draw on the screen where the mouse is. Does anyone happen to have a link to something that explains how to do this? Google doesn't seem to understand what I'm trying to search for (keeps giving me tuts on moving things with UI not moving the UI itself)

[leaden ice]

Are you trying to make a custom mouse cursor?

[runic cave]

no, trying to make a popup menu that appears at the mouse position when I click on an object

I'm making some progress but this UI stuff is so confusing

[leaden ice]

Simplest way is basically to set your canvas to Screen Space - Camera.

Then you can project your mouse position to world space and position the ui element there

basically:

Vector3 mousePos = myCam.ScreenToWorldPoint(Input.mousePosition);
tooltip.transform.position = mousePos;```

and again - this only works in Screen Space - Camera

Im attempting to get the colors in a sprite to check if the image is completly transparent. Though every single image is returning the colors as full black and reading as transparent. Ive read the documents and since my texture is created at runtime is should automatically be readable, why are all the pixels returning as black?

//CREATE SPRITE
  Sprite slicedSprite = Sprite.Create(texture, new Rect(xPos, yPos, 16, 16), new Vector2(0.5f, 0.5f), 100.0f);

//RETURNS TRUE ALWAYS?
if(!IsTransparent(slicedSprite.texture)) { }

//BOOLEAN, EVERYTHING IN INSPECTOR IS BLACK
public List<Color> loadedColors = new List<Color>();
bool IsTransparent(Texture2D tex)
{
    Color[] pixels = tex.GetPixels(0);
    foreach(Color co in pixels)
    {
        loadedColors.Add(co);
        if (co.a == 0)
        {
            print("isAlpha");
            return true;
        }
    }

    return false;
}

[leaden ice]

you're doing !IsTransparent so you;re actually checking if it isn't transparent

you're also adding every pixel to that list which is going to grow quite large 😮

[sterile gate]

Yes, I dont want any transparent sprites, but even the sprites that should not return transparent are returning alpha true. Actually it only loads 210 into the list, which is it look like it actually stops reading pixels after 210. There is no error or clear list called, why is it just stopping? o_O

[leaden ice]

your code is only checking if there are any transparent pixels in it

is that what you want?

It will stop when it gets to return true; ofc

[sterile gate]

Yes im iterating through a list. So it seems like its only checking one tile then stopping.. and not running the isTransparent function anymore

  for (int i = 0; i <= 69; i++)
        {
            if (curColumn >= 5)
            {
                xPos = 64;
                yPos -= 16;
                curColumn = 0;
            }

            //CREATE SPRITE
            Sprite slicedSprite = Sprite.Create(texture, new Rect(xPos, yPos, 16, 16), new Vector2(0.5f, 0.5f), 100.0f);

            if (isAnimated && !IsTransparent(slicedSprite.texture) || isVariant && !IsTransparent(slicedSprite.texture) || !isAnimated && !isVariant)
            {
                //ADD TO LIST (WE SAVE AND LOAD DATA BASED ON THIS LIST)
                gameMaster.mapSprites.Add(slicedSprite);
                textureSprites.Add(slicedSprite);

                //SPAWN THE BUTTON
                //IF WE ARE ANIMATED OR VARIANT, ONLY SPAWN THE BUTTON ON THE FIRST SPRITE, SAVE THE REST TO THE LIST
                if (isAnimated && totalpos == 0 || isVariant && totalpos == 0 || !isAnimated && !isVariant)
                {
                    baseSprite = slicedSprite;
                    GameObject spriteButton = Instantiate(buttonPrefab, containerPrefab);
                    spriteButton.transform.GetChild(0).GetComponent<Image>().sprite = slicedSprite;
                    spriteButton.gameObject.SetActive(true);
                    spriteButton.gameObject.name = xPos + "," + yPos;
                }
            }
            //MOVE TO THE NEXT TILE BUTTON
            xPos -= 16;
            ++curColumn;
            ++totalpos;
        }

This is slicing a texture, iterating through the tiles. and im checking if any are transparent, not to add them to a list Im using

[leaden ice]

I don't see how that part is really relevant

also

you are anaylizing the entire texture every time

not just the individual sprite

And of course: #archived-code-general message

[sterile gate]

ah. does "sprite.texture" reference the entire original texture, and not make a texture reference based on the sprite size..?

I think that makes sense as to whats going on if thats whats happening. Im not sure how to grab the colors inside of my sliced sprite so I can check if its just transparent or not

[leaden ice]

It's the entire texture

[leaden ice]

using the sprite of course

I mean you even calculated the pixel range already: Sprite slicedSprite = Sprite.Create(texture, new Rect(xPos, yPos, 16, 16), new Vector2(0.5f, 0.5f), 100.0f);

Honestly the most efficient thing though will be to get the color array outside this whole loop one time and just reuse it over and over

checking the section you want each time

and, don't forget the most important thing here that I keep mentioning:
#archived-code-general message

which is not the same as all transparent

[sterile gate]

Oh wow that makes much more sense. Thank you!

[blissful dust]

My game is meant to have a pilotable airship with physics (I dont want it clipping through the ground) that the player can walk around on but also control. My current solution is to have a CharacterController on my player handling movement, and a Rigidbody on my airship that I add forces and torque to in order to control it. I also set up a trigger box collider to detect if the player is on top of the ship, in which case it makes the player a child of the ship to maintain it's speed. However, because the player and the ship both technically use a rigidbody, the ship (which ignores gravity) is pushed down by the player (who is being forced down by gravity). Is there a good way of making the ship ignore the player's effect on it? I thought about increasing the mass of the ship to an incredibly high number so the player doesn't affect it, but this sames janky, and I saw something about using a physics scene to calculate the player position, but I've never done that and I'm hesitant to implement a complex solution when it might not be needed.

Also, I've found it's not a great idea to ask for a solution for something when there could be an entirely different approach that works better, so if anything I said above could be changed to simplify the entire process, that would be great

[spring creek]

You could disable gravity on the player when it's a child of the airship

Or set a negating velocity of y +9.8

[blissful dust]

It's not "gravity" as in like I have gravity enabled on a rigidbody, I'm just moving the charactercontroller down to simulate gravity, but if I were to stop doing this then the player wouldn't be able to jump

[nocturne grove]

You could also set the ship to kinematic

While not moving*

[blissful dust]

then it won't respond to collisions right?

[spring creek]

Kinematic rigidbodies respond to collisions

[blissful dust]

once it starts moving if I set it to non-kinematic (enabling physics) it'll immediately start to drop again tho right?

[nocturne grove]

It won't respond like it's being pushed

[spring creek]

The ship? I thought you said it ignored gravity?

[blissful dust]

I had to double check the unity docs there but from the docs:

If isKinematic is enabled, Forces, collisions or joints will not affect the rigidbody anymore.

[blissful dust]

yeah I just disabled gravity on the ship's rigidbody, but it's the player pushing down on it that's forcing it downwards

[nocturne grove]

The issue is the player character pushing the ship. The ship is in zero gravity, but the player pushes the ship

The issue here is the player pushing the ship

[spring creek]

It means being pushed, but collision EVENTS still happen. That's what I thought you meant, sorry

[blissful dust]

ahhhh gotcha

[spring creek]

So the PUSHING is the collision that wouldn't happen

[nocturne grove]

The ship won't be pushed around while Kinematic

Which could be an issue if you want asteroids to do that

[blissful dust]

it gets kinda paradoxical though, if I were to slam the ship into a wall and it is kinematic, would the ship just go straight through the wall?

[nocturne grove]

However, if you want to do kinematic, you can make special collision events for this cae

[blissful dust]

but if I make it non-kinematic it'll respond to my player

[spring creek]

No. It would stop, but not bounce
Depending on the wall rigidbody/collider settings of course

[blissful dust]

gotcha

well yeah my wall would probably just be another kinematic rigidbody, its not gonna move or anything

[spring creek]

So it would stop and throw an OnCollisionEnter event that you could handle manually I guess

[blissful dust]

gotcha, so I guess I could just like calculate how hard it should bounce off the wall myself and apply that to the rigidbody

[nocturne grove]

Exactly

[blissful dust]

okay cool, I'll try that out and see if I still need any help, really appreciate it guys

[nocturne grove]

np

[spring creek]

You could do like a trigger collider and when it gets close to walls and things it turns into a non Kinematic rb, so that it bounces correctly, then on exit set it back. It would be pushed down a bit but it miiight work.
You could even remove the player as a child so they go flying haha

I dunno if that would be worthwhile at all lol

[blissful dust]

lmao I mean it's worth looking at, maybe I could disable the character controller for like a couple hundred milliseconds so the rigidbody's velocity sticks once i turn it back to kinematic

seems janky though, I'll try manually calculating it first

[wintry crescent]

Why does this line
if (!gameObject)
throws an error

Your script should either check if it is null or you should not destroy the object.```
isn't this line supposed to check if it's null or not?

[leaden ice]

you need if (!this)

but really you should just - not call whatever function this is if this thing is destroyed

[wintry crescent]

I'm just fixing a package I imported

it removes the call from the event that called it inside that if

[silk niche]

i know i can just make it move along the spline, but don't know how to access to other stuff

[wintry crescent]

it did work, thank you

[foggy pasture]

is anyone experienced with parrelsync? i'm encountering an issue where scriptableobjects don't match the parent project, often in strange and random ways

[leaden ice]

Is the data that doesn't match serialized?

[foggy pasture]

one sec, let me find an example and check

it's happening primarily with a field that i have an attribute attached to

[leaden ice]

what attribute?

[foggy pasture]

[CustomPropertyDrawer(typeof(ScriptableObjectIdAttribute))]
public class ScriptableObjectIdDrawer : PropertyDrawer {
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label) {
        GUI.enabled = false;
        if (!ClonesManager.IsClone() && (string.IsNullOrEmpty(property.stringValue) || int.TryParse(property.stringValue, out int number))) {
            property.stringValue = Guid.NewGuid().ToString();
        }
        EditorGUI.PropertyField(position, property, label, true);
        GUI.enabled = true;
    }
}

it's just to generate unique guids for scriptableobjects

i assume i need to serialize this field somehow?

[leaden ice]

is the id field not serialized?

I can't imagine it's much use without being serialized

[foggy pasture]

it should be, it's visible in the inspector

[leaden ice]

It's visible in the inspector because you literally have a property drawer drawing it
EditorGUI.PropertyField(position, property, label, true);

is it serialized?

[foggy pasture]

i'm unsure of how to check outside of inspector visibility

[leaden ice]

it needs to either be public or marked with [SerializeField]

[foggy pasture]

i assumed it was because of the propertyfield docs describing what it creates as a serialized property

[leaden ice]

and it needs to be of a serializable type

[foggy pasture]

it is public, but let me try it w/ serializefield

[leaden ice]

it will make no difference

public is fine

[foggy pasture]

ah ok

so it probably isn't serialization causing the issue in that case

[manic maple]

controller.Move(move * speed * Time.deltaTime);

    if(Input.GetButtonDown("Jump") && isGrounded)
    {
        velocity.y = Mathf.Sqrt(jump * -2f * gravity);
    }

    velocity.y += gravity * Time.deltaTime;

    controller.Move(velocity * Time.deltaTime);

can you reference a charactercontroller.move twice? how does that work?

[somber nacelle]

it moves the CharacterController twice in that frame

[leaden ice]

YOu can but you should really only do it once per frame or it will be buggy

[lean sail]

.move is a function also, you can call a function however many times u want

[somber nacelle]

it's pretty typical to see this in tutorials, and even on the unity docs. it's technically better to do your move all in one call though

[manic maple]

yeah i'm following a tutoriel and they used it twice without explaining. didn't know they added up. Thanks!

[leaden ice]

You can and should combine them. For example:

Vector3 horizontalMovement = move * speed * Time.deltaTime;
Vector3 verticalMovement = velocity * Time.deltaTime;
controller.Move(horizontalMovement + verticalMovement);```

[astral sky]

Are there any special or unique rules for instancing gameobjects in DoTS? Not sure If I should ask it here or make a thread in the dots forum, but I thought it was simple enough to be posted here
Is it just the usual Object.Instance(prefab)?

[leaden ice]

Everything in DOTS doesn't touch GameObjects, so I imagine all the normal stuff is how to do it.
The main thing though is you're not allowed to do any GameObject related things on any thread except the main thread

[astral sky]

Well, yeah but since I have authoring components, I dunno how that's handled if instanced right there at runtime, considering that has the baker... steps
Baking only happens in the Editor and never in-game

I'm used to having Scriptable Objects (as spawncards) which hold prefabs, I started with dots past week and I'm pretty much rethinking how I gotta do stuff and the rules (like can I mix a gameobject that has a authoring component (ECS) and usual monobehaviors? that's what cameras are right now, as there's no ECS version of cameras?)

So I don't know how much can it be dots, how much it has to be dots, if I can mix and match

etc

[leaden ice]

I think you should definitely ask in #1062393052863414313 because I've never used it

[foggy pasture]

re: my earlier issue

you just need to add ```

        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();

after the guid changes

to sync the change to parrelsync

[sonic vault]

how do I get a true or false if a button is being held or pressed with the new input sytem and invoke unity events?

[leaden ice]

void MyFunction(InputAction.CallbackContext ctx) {
  bool isPressedCurrently = ctx.ReadValueAsButton();
  bool wasPressedThisFrame = ctx.started;
  bool wasReleasedThisFrame = ctx.canceled;
}```

[sonic vault]

lemme try that real quick

ok that did not really work, can you tell me how I send my code to you?

[leaden ice]

show your code and also very importantly show how you set up the input action

and explain in what way it didn't work

[sonic vault]

I have a bool called is firingcontisully but the bool does not change

[leaden ice]

what do you mean by "change"?

[sonic vault]

It set it as false in the start and it remains as false even when im touching the the button

[leaden ice]

how arew you checking what it is

Also you never shared:

show how you set up the input action

[sonic vault]

isFiringContinusly is a public

[leaden ice]

so you mean you're looking in the inspector

[sonic vault]

yep

[leaden ice]

so is the code actually running?

Is your thing printing?

[leaden ice]

And please show this

[sonic vault]

I have it set up as an event (the onFire is the is the one where focusing on)

[leaden ice]

yeah but i want to see the configuration of the action itself

The "Fire" action

[leaden ice]

Also this^

[sonic vault]

the input dected is printing

[sonic vault]

is this what you mean

[leaden ice]

get rid of the tap interaction

[sonic vault]

ok on it

[leaden ice]

also it's not going to "continuously" do anything really

this will only be called when you actually press or release the button

[sonic vault]

by golly gosh that worked

but why though?

[leaden ice]

you probably want something like:

void Update() {
  if (isFiring) DoSOmething();
}

void OnFire(InputAction.CallbackContext ctx) {
  if (ctx.started) isFiring = true;
  else if (ctx.canceled) isFiring = false;
}```

[leaden ice]

The tap interaction changes how everything works

don't do it if you don't know what you're doing

[sonic vault]

thank you so much man you are a real one

[blissful dust]

yeah it seems like this isn't true, or at least I can't figure out how to get the OnCollisionEnter event to fire. I have a cube with a kinematic rigidbody and a box collider (I also checked provides contacts) that my ship is trying to collide with, and then my ship is a rigidbody with a collider on one of it's children.

[spring creek]

The rigidbody and collider are on different objects though (for the ship)?

[blissful dust]

yeah, I just tried putting a box collider on the ship though and it didn't seem to make a difference

[copper yew]

Heyyy

[spring creek]

Does the OTHER thing its colliding with have a collider? Both need a collider and one needs a rigidbody. Pretty sure it has to be the same object with rb and collider too, but not sure

[copper yew]

Holy moly i can ask my questions after long time

[blissful dust]

yeah, the thing it's colliding with actually has a kinematic rigidbody and a collider on it

[spring creek]

Hmm, not sure. It SHOULD work. Did you touch the collision matrix?

[blissful dust]

nope, haven't messed with it at all

lemme send a screenshot or two just to make sure im not completely overlooking something

[spring creek]

I would put a debug in the oncollisionenter, not behind an if or anything

Just to help with checking

[spring creek]

Hmm ok, and the debug never fires... weird

[blissful dust]

yup, not really sure why it wouldn't

[spring creek]

Ah dang
https://docs.unity3d.com/Manual/CollidersOverview.html

Looks like one has to be non kinematic

[blissful dust]

I just created a cube with only a box collider and rigidbody and if its non kinematic it works

[blissful dust]

yup, sounds about right

guess im back to square one

[spring creek]

Yeah sorry!

[blissful dust]

nah its all good, it was a step in the right direction I think

[quartz folio]

Note I host a much more readable version (imo) of that graph here fyi

[wispy raptor]

which unity version should i use if i wanna use .net 7 in unity?

currently i am using unity 2022.3.3f1, it uses .net 6, i wanna use .net7

because .net7 has a lot of new features

that are very useful

also some performance improvements

[late lion]

Unity does not use .NET 6. It uses a modified version of Mono, that's based on .NET Framework 4.7, but with modifications to allow a subset of C# 9 and .NET Standard 2.1 features.

They are in the progress of switching over from Mono to CoreCLR, which is what .NET 6 and 7 are based on. That will take a while.

[wispy raptor]

aaa okz

thank you

@wispy raptor https://forum.unity.com/threads/unity-future-net-development-status.1092205/

Yeah I was being dumb and thinking c# version lol. But this is the status for .net

[brave cove]

Hello :>

I'm encountering a rather problematic issue and I wonder if I could get some help in here ^^' I couldn't find anything relevant on internet
So I have this Coroutine which I use to transition between multiple user-selected background music themes (see first attachment)
I call it once upon starting the game, and then transition smoothly when switching themes like so (see second attachment)

The problem is the following: I can only select each theme once, after which it doesn't switch anymore. I think it has to do with how coroutines can only run once (or something), and I've been stuck on this issue :>

[brave cove]

second attachment is called upon switching dropdown options, btw

[leaden ice]

coroutines can only run once (or something)
Coroutines can run as many times as you want. You just have to call StartCoroutine each time you want it to run

[leaden ice]

In your second screenshot it looks like you're trying to fade your sound in AND out at the same time

[brave cove]

so it's supposed to work then

it's called once at the start and the SetThemeis called everytime I switch

[brave cove]

yeah, and it works fine

problem is I can only select each theme once

[leaden ice]

Probably because your audio sources are not set to loop

so once they play, they've played

[brave cove]

they are TwT

[leaden ice]

time to start adding logs

[brave cove]

I'll do so then

oh also

last time I checked the audiosource volume while switching

it was like, going back and forth

so I think it calls both FadeSound in and out, or something

[leaden ice]

sounds like yhou have multiple coroutines competing with each other

[brave cove]

there's only one tho

[leaden ice]

you wrote one coroutine method, but you are starting it many times in many places

[brave cove]

wait, is it maybe that you can't start the same coroutine simultaneously with different parameters?

[leaden ice]

you can

there's no limits on calling the coroutine

[brave cove]

ah

[brave cove]

SetTheme calls both only once tho

[leaden ice]

and how many times are you calling SetTheme?

[brave cove]

once everytime I switch dropdown otpion

[leaden ice]

how are you calling it

can you show that code

[brave cove]

here

[leaden ice]

Maybe add a log to it and make sure it's not being called more often than expected

[brave cove]

aight

so I:

• started the game (Starglitter Sky was preselected)
• switched to Wings from Beyond
• switch to Ode to Spring
• switch back to Wings from Beyond

it seems the FadeSound in isn't called

here are the logds

• 1 when calling SetTheme

[dusk apex]

Un-collapse it please so we can understand the sequence in which events are occurring.

Relative to the logs.

[brave cove]

nvm, so it does call it x) I didn't see it cuz of the collapse

when I look at the volumes of each audiosource, whenever I go back to Wings from Beyond, it's volume isn't actually going up

idk what causes this

I know what the problem is, it's this line

is there a way to save the volume outside the coroutine? because sound is a parameter of that coroutine so idk if that's possible

[leaden ice]

save it in a separate member variable

but yeah this makes sense, once it goes to 0 it will never come back up

because 0 * anything is 0

[brave cove]

it's what i noticed x)

[leaden ice]

you'll want to save the "max volume" variable somewhere

and never change that

so sound.voume = maxVolume * i; should be in the loop

[brave cove]

hmm I dunno how it couold be done tho

[leaden ice]

?

[brave cove]

I stuck to this for now, cuz of all em have 0.5 volume

[leaden ice]

but why is that so hard?

also volume is almost definitely not 0.5

nvm audiosource volume is 0-1

so that's probably ok

[brave cove]

well, how can you set maxVolume once as a variable outside the coroutine?

[leaden ice]

float maxVolume = 1;```

or even const float maxVolume = 1;

[brave cove]

yeah, but shouldn't it depend on the sound.volume in some way?

[leaden ice]

why so?

[brave cove]

well what if one theme is slightly louder than the other, meaning i'd have to set it to 0.4, for instance

[leaden ice]

then you could do something like:

Dictionary<AudioSource, float> maxVolumes = new();

void Awake() {
  foreach (AudioSource source in themes.Keys) {
    maxVolumes[source] = source.volume;
  }
}```

and then in the coroutine:

float maxVolume = maxVolumes[sound];```

[brave cove]

oh wow

I didn't think of that actually

I'll try it, thanks! :>

[green radish]

how might someone create an array of variables, if that makes sense? for instance having each member of the array contain one int and one string variable

[unreal sparrow]

Can someone help me with this code? Basicly I am trying to get my eyelid blendshape value to reach 100 as my eye y rotation looks up and also for the value to decrease as it start to rotate down. I got the blendshape to be affected as the eye looks up but the value instantly shoots up to 100. I've been trying to smooth it out with lerp. Also I need it to decrease as starts to make it way down the y rotation value.

[wispy raptor]

when you code a customeditor, is there a method to show the default inspector for an specific type? for example if i have a generic type, i would like to show a text field if it is a string, a numeric field if it is a int or float, etc... or must i use just a kind of switch?

[leaden ice]

PropertyField

[wispy raptor]

thanks

[lean sail]

You would create some class or struct to hold these variables then have an array of that class or struct. Could also do with tuples but you really shouldnt need to do this often

[green radish]

I intend to use this for storing the name and number of frames for animation cycles

I would get the name and number from the variable and feed it into the custom animator I'm building

[brave cove]

ig a Dictionary<string, int> would do

dunno much tho

[night harness]

Hey friends. Not a super specific question but more of a general coding practice vibe check. Theres been once or twice where I have a state machine that I want to fire off events based on when the state changes, It feels messy to have a delegate or unityevent per enum state but is that just my head being silly or is there an actual better way to do this

I thought about a UnityEvent that passes through the new state but i figure having a bunch of events is better than calling a bunch of irrelevent functions just to fail a comparison with that state

[mighty yew]

I have a class called Attack, and I want to have a bunch of objects (lets say 20) that all inherit from this class. The class contains 2 ints, and an "animationClip". Is there a way to effeciently create these "attacks" and be able to reference them?

[night harness]

Kinda sounds like you might want to look into scriptableobjects?

Depends on your usecase

I'm guessing those 2 ints are attack stats open for designers to tweak?

[mighty yew]

Yeah they are, ill look into scriptableobjects

not really sure if this is the best way to do it ngl

[spring creek]

You could have a field for an attack scriptable object and just have different SOs added in and out to the ONE attack class, like Batby was saying

Or similarly, use a serializable struct and have prefabs with the different values

is there any way to stop this weird Editor UI behavior? This is an array of my custom class that stores cycleName(string) and cycleLength(int) variables, this overlapping only happens on Element 0, on every other Element the array UI expands to make room

[sonic oyster]

You seem to want me to explain my question in a detailed manner, as far as I understand.

[spring creek]

Well, just in any manner. You have an issue RELATED to Json, that's all we know as of now

[spring creek]

Ah, that's annoying. I dunno. It might have to be a custom editor script unfortunately. Check here

[green radish]

it means dont say "I have a question", just say the question

saves chat space and people can get straight to answering

[sonic oyster]

I've written a login code and I'm accessing this code from PHP. However, whenever I try to execute the login process when status = true, JsonUtility.from doesn't allow it and gives an error. I've also included its screenshot.

[sonic oyster]

I understand, sorry

[pure cliff]

Breakpoint it, debugger attach, see what the actual raw string value is

[night harness]

ScriptableObjects for stuff like this can feel abit redundant and bloaty but it's really nice to have them as disconnected files like that. What you can do is have your Attack SO's store those three values and then when whatever ends up using them, they grab those values off the scriptableobjects (on update, on a custom loading function etc.)

[green radish]

I just discovered that this exact issue has been a known bug for over a year now, its specifically an issue with the modern editor UI for arrays

the old UI doesnt have it

[spring creek]

Oh really? 😂 sad but also a tiny bit funny.

Sometimes when we move forward we stumble I guess

[green radish]

probably something to do with the elements being reorderable being broken, since turning that off is what fixes it

[prime sinew]

it was fixed in a later Unity version, but i forget which

[green radish]

I'm a bit afraid to update my project to a new version since that has an alarmingly consistent pattern of breaking my projects beyond repair

[prime sinew]

you can try making a backup first 🤞

i think it was fixed in 2021.3.5
https://unity.com/releases/editor/whats-new/2021.3.5#:~:text=Editor%3A Fixed ReorderableList first element height when the element uses PropertyDrawer. (1409773)

[night harness]

Hey friends. Not a super specific question but more of a general coding practice vibe check. Theres been once or twice where I have a state machine that I want to fire off events based on when the state changes, It feels messy to have a delegate or unityevent per enum state but is that just my head being silly or is there an actual better way to do this
I thought about a UnityEvent that passes through the new state but i figure having a bunch of events is better than calling a bunch of irrelevent functions just to fail a comparison with that state

lmao ty for that

[green radish]

the irony, as I just now learned, is that it was fixed the very next year from the version I'm currently using(2021)

[prime sinew]

dear god, it was around for that long

2020 to 2021 might be a big jump. all the best if you decide to upgrade your project

[green radish]

it was fixed in 2022

[prime sinew]

oh

oops, i forget editor versions dont reflect year of release always

[green radish]

I started my project in 2021 and out of fear of file corruption chose not to update to the next version

[prime sinew]

well, can always make a backup and experiment on upgrading that. that's all

[green radish]

true

[hidden flicker]

Currently having Schrodinger's bug

[pure cliff]

Race condition calling it now

[hidden flicker]

...ok let me finish lmao

When my player is selected in the inspector, they move normally. But when they aren't, they move much faster than they should

[pure cliff]

Oh fascinating

What's your code for player movement look like?

[hidden flicker]

Before you see it

I know it's messy

Please forgive me

[pure cliff]

I'd maybe think it's perhaps your inputs are doubled somehow or something

[devout solstice]

So i forgot to write my script using fixed update right, and it’s already basically finished, so i switched the update to fixed update and when i press tab to open the gui, i have to push tab multiple times to get it to open i don’t have any clue why that would be

[leaden ice]

You can't process input in FixedUpdate

Or that happens

[devout solstice]

oh shit

ok

[leaden ice]

Input processing goes in update

[devout solstice]

gotcha thank you

[hidden flicker]

Anyone got help for the... confusion

[devout solstice]

this will work fine right?

[prime sinew]

Try and see

[blissful dune]

hello to all, anyone know how can read a json and convert into a object list?

[leaden ice]

Unity's JsonUtility or Newtonsoft JSON for example

Basically any json parsing library

[blissful dune]

i try to use newtonsoft but cant add into my proyect

[leaden ice]

https://github.com/jilleJr/Newtonsoft.Json-for-Unity/wiki/Install-official-via-UPM

[blissful dune]

ty

lovely

JsonUtility only parse a single object...

[devout solstice]

ive forgotten how while loops work

i know youve gotta return or else itll crash unity

but thats not working right

[leaden ice]

No you need to just not make the loop infinite

[devout solstice]

oh

[leaden ice]

It will run untill the condition is false

[devout solstice]

i want it to run as long as a certain button is pressed

[leaden ice]

You don't want a loop

[devout solstice]

i had it like that without return but it crashed unity

[leaden ice]

You want Update

Not a loop

[devout solstice]

oh

[leaden ice]

Then your condition never became false

[devout solstice]

it would when i let go of the key

[leaden ice]

Doesn't matter because the next frame will never run

Input is only processed once per frame

At the begining of the frame

[devout solstice]

if i use a if statement it still only runs once on each key press

[leaden ice]

if statement with what condition

[devout solstice]

maybe i was using the wrong input thing

[leaden ice]

Yes

You were

[devout solstice]

ah now it works

[nova magnet]

the gun is not using the correct ammo type

This is frustrating and I hope someone is able to help you but you have to admit that's at least a little funny

[nova magnet]

[edgy ether]

So i have a texuture that i'm trying to change the settings to while in editor. just some basic settings like , disabling mipmaps, changing mesh type and making it readable.

problem is, i can't simply change it through the inspector because the duplicate texture gets created in ram (i believe) leaving me unable to change the settings.
so i want to change these settings using code while in the editor. how would ii do this?

[worn stirrup]

Uuuu what's the best way to measure the physical length of a sprite I have in-scene

wait that sounds googleable

oh prolly rect

[thorny spindle]

Are there any good Unity Open Source game/projects out there?

[worn stirrup]

This has somehow been such a long rabbit hole of such bad code 😅 I'm trying to set up a 2D chain-link spawning system, but trying to figure out how tall a link is to precisely offset the new one is proving wildly difficult

aaand I just got it lol

time to fis physics for 2 hours

[spark flower]

can someone help me out

why am i getting this error

[prime sinew]

Either _items or items[j] is null

[spark flower]

from the print it seems _items is not null

like it is length of 1

[prime sinew]

Since you initialized _items in line 43, it should be items[j] that's null

Yeah

Check _items[j] then

[spark flower]

and j is 0 basicly

[prime sinew]

Oh _item might be null

I forgot to see the right side of =

[spark flower]

from the print its seen that its not

[prime sinew]

Is the error message recent

[spark flower]

thius is Item

what do you mean recent

[prime sinew]

Like the line number hasn't changed by you changing the code

[spark flower]

nothing has changed

it is as i have it rn

[prime sinew]

Try debugging items[j] and _item

Then show the log

Just to confirm

[spark flower]

if i just print _item, it just shows Item, so i print item.name and it shows correctly

[quartz folio]

🌈 use the debugger

[spark flower]

ok

it seems its null

which doesnt make sense to me

any ideas?

[quartz folio]

Use the debugger and you'll see exactly what's null and how you might not be assigning it

because you can just step over the code and see it execute, seeing the values it contains, etc

[spark flower]

where is this debugger

[quartz folio]

https://unity.huh.how/programming/debugging/debugger
-> https://www.youtube.com/playlist?list=PLReL099Y5nRdW8KEd59B5KkGeqWFao34n

[spark flower]

and really thats the whole code

dont you have an idea why its null

[lean sail]

no one wants to 🥣, learn how to debug 😊

[spark flower]

its just an array extending function, a simple answer wuld be best

[quartz folio]

You never assign it a value, so it is null.

You could see this if you learnt to use the debugger, and then because you knew how to use it you would never have any more questions

[spark flower]

well how do i assign it a value

[quartz folio]

new

[spark flower]

Item[] _items = new Item[assets.Length + 1];

and what does this do then

doesnt it give it default values

[quartz folio]

No

Classes are null by default.

[spark flower]

i see

[quartz folio]

Again, please learn the debugger, it takes 1/2hr and then you're set for life

[spark flower]

well the problem was i didnt know i have to give new to every single entry,

the debugger wuld tell me its null and ill still be confused as to why

the debugger is not the right option in this case

[lean sail]

Sounds like someone whos never used the debugger

[quartz folio]

You would have seen that it was null in the array without every having to put down a single print statement, you would have seen you writing your new values into the array, and then you would have inferred you needed to assign something to that index

If you are using print statements for debugging you should be using the debugger instead

[spark flower]

i wuldnt have guessed that i have to make a new class() for every entry

[quartz folio]

You don't, you only have to make it for the one that is null

[spring patio]

Anyone have an idea how to disable Button GameObject in Script? SetActive(false) doesn't seem to work.

[spark flower]

well theyr all null since its a new array

[quartz folio]

but you're writing elements into it, so those will not be null

[prime sinew]

Show your code and what you're trying to disable

[quartz folio]

Do you want the button disabled, or set uninteractable, or the gameobject it's on deactivated?

[spark flower]

if your refering to the ones in the loop, that loop doesnt run when i extend it the first time, since its a length of 0

and id bet ill get an error for the loop if i dont put new class() for every iteration

[quartz folio]

With the way you're doing it, yes, you have to new each one

[spark flower]

is there another way of doing it?

[quartz folio]

Depends whether you want the arrays referencing the same objects or not

[spring patio]

the entire button, as in the gameObject checkbox

[quartz folio]

Also, why not just use a List?

[quartz folio]

Then button.gameObject.SetActive(false) would do it

[spring patio]

ooooo

tysm 😄

[spark flower]

im just extending an array, theres no other objects

[spring patio]

forgot about the gameObject part :/

[spark flower]

becouse im an array andy

[quartz folio]

You're creating a whole new array every time you call this method, you are not extending anything

[spark flower]

i know

[quartz folio]

So, do you want the new array to reference the same objects as the original one?

[spark flower]

yes

[quartz folio]

Then assign them directly instead of assigning each member one by one

Or use Array.Copy or something

[spark flower]

well how do i resize it after that

[quartz folio]

Don't do this inner member assignment stuff, instead do _items[i] = assets[i];, or use Array.Copy to replace the whole loop

Or just use a list and don't do any of this

[spark flower]

im alredy doing that

just copying the array wont make it a new size

and i need it a new size

like i sayd the function is just an array resizing function

i dont think theres a way without iterating thru everything

[quartz folio]

I can't get through to you, so I'm out, someone else can help, but I'd advise not bothering as this is absurd

[spark flower]

well your not making much sense to me

[quartz folio]

I've spent far too long talking to you, after you refused to use the debugger and have shown no indication you ever plan to I should have stopped

[spark flower]

the debugger is not nececery here, the whole code in question is in one function, and is basic

[swift falcon]

    [SerializeField]Vector2 HullDimensions
    {
        set
        {
            GetComponent<BoxCollider2D>().size = value;
            GetComponent<SpriteRenderer>().size = value;
        }
    }

is there any way to do something like this so that i can change both of these values through the inspector ?

[limber herald]

You can do Array.Resize(ref _items, _items.Length + 1), then set the last value of the array using _items[_items.Length - 1] = newValue, though if you'll be resizing the array a lot, I suggest you replace the array with a List, since it gives you access to the Add(), and Remove() functions

[quartz folio]

No

[green radish]

is there any way to modify Unity's Tilemap system to allow per-tile data storage?

[swift falcon]

mega unfort 😔 ✊

[green radish]

like storing a health value that can be accessed and decremented, but only effect the one tile

[spark flower]

what do i need to use for Array?

[quartz folio]

You would have to make a custom editor or drawer that found those properties and drew them using PropertyFields, but there's no straight forward way

[limber herald]

The Array class is a static class from the System namespace, so you don't have to replace it with anything really. And if you get an error saying "Array" not found, just make sure you have using System; at the top of your code

[spark flower]

        Array.Resize(ref assets, assets.Length + 1);
        assets[assets.Length - 1] = _item;```

so this basicly

[quartz folio]

and with _items[^1] = newValue we can further reduce the hellcode to nothing and it will disappear from existence

[spark flower]

assets[^1] = _item; so just this?

[spark flower]

this doesnt work

[dusk apex]

What's the error?

Unary expression should work unless length is zero or something.
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/proposals/csharp-8.0/ranges#systemindexcs var array = new int[] { 1, 2, 3, 4, 5 }; var thirdItem = array[2]; // array[2] var lastItem = array[^1]; // array[new Index(1, fromEnd: true)]

[simple egret]

Maybe they're on an older version where indices aren't supported

But who knows, without the error message

[lean sail]

my moneys on they didnt assign _item to be a thing

[green radish]

is this a question better suited to #archived-code-advanced ?

[scarlet viper]

Changing Transform on a Prefab instance (Placeholder for referenced MonoBehaviour in Prefab instance (1)) is not allowed.

cant compile i have this error

its something with TEXTmeshpro

[winged mortar]

I don't think it's possible tilemaps are just for displaying and creating a collider, if you need any custom scripts on a specific tile you are going to have to use prefabs i think

[dusk apex]

Doesn't sound like a code question but a feature or some other request. Maybe #💻┃unity-talk or the non discord server if you're okay with non immediate but more thorough responses.

[quartz folio]

my money's on them removing the other line of code and expecting it to work. Hence why they said "so just this?"

[edgy pumice]

Hello, everyone.
I was wondering, whether I am on the right track with this one or whether there are better ways to do it.

I'd like to instantiate a prefab of certain dimensions at distance, corrected by raycast hit on specified layers and collision of said prefab.

My thought is to check for raycasthit2d . point - ( bounds.size.y / 2 corrected by direction of the prefab ) and... decrease the checks by increments until I can fit the bounds without colliding with anything.
But this seems tedious and unintuitive. Any thoughts?

[spark flower]

out of range

[dusk apex]

So a length of zero
