What Starcraft 2 AI does afaik is check whether or not it goes closer to the target or not over 1 second.
So if you grab a bunch of marines, and all double click them on the same spot they fight for that place like your skelly for 1 second, and then it force stops all of them. There is a GDC talk about Starcraft 2's pathfinding/navmesh, imho it has the best fast and responsive movement for strategy games currently, suggest you look at that talk.

[west lotus]

Well another idea is to calculate formation possitions based off the player pos. We do this in one game but for enemies attacking the player

[cyan vector]

This is what I had in the beginning. The Formation would rotate and move whenever the player rotates and moves - that was incredibly annoying, so I added the margin, so Agents don't move, as long as the player is within a certain range of the formation, meaning, he can walk through the whole formation. Causing these problems.

[cyan vector]

I will have a look at their talk and maybe implement the solution as it seems to solve all problems.

But I won't fully stop them, as I also have destructible Buildings and enemies / allies could die, allowing other allies take their place, I will just slow them down a lot until they start getting closer to their target again and then reset their speed. Something like that maybe.

[west lotus]

You would need to recalc the formation based on player pos, not just have a bunch of transforms parented to the player. If player moves check distance to each point, if its bellow min distance shift point away from player.

[cyan vector]

That's a solution I haven't thought about yet but actually possible. Hmmm, maybe I'll implement both to solve all cases.

Thanks @west lotus & @main shuttle, after being stuck on this problem, I finally have some solutions. 😄

[west lotus]

Good luck

[west lotus]

Btw are you making a Overlord ispired game? I loved those games.

[cyan vector]

Yes, working towards a playtest, hopefully somewhere at the end of this month - PM me if you want to test it. ^^

[west lotus]

Im afraid I wont have time to playtest it, but I wish you all the best

[cyan vector]

Np ^^ And thanks 😄

[blazing trail]

Anyone know how to solve this problem?
This happened when I finished moving the unity editors folder from C drive to E drive
This is the first time I have a problem like this, and I don't know how to solve it, I'm a beginner 🙂

[plucky inlet]

Whenever you move a project, be sure to remove library folder. Unity will rebuild everything for you, cause paths to temporary files are now messed up as you changed the path with moving the files

[blazing trail]

okay, I'll try to delete my library folder

[urban owl]

if a gameobject is created from prefab, the component property value modified by [ContextMenu] , is not able to serialized !!!!!

[plucky inlet]

What are you trying to do?

[urban owl]

place a prefab to the scene, the prefab has a Mono script.
use [ContextMenu] to modify this component value.
but it's not saved, after switch scene

[plucky inlet]

Saved to the prefab or the scenes instance of the prefab?

[urban owl]

the instances

[plucky inlet]

so you save the scene after editing values? What is your code actually?

I use gameObject to FindObjectWWithType first,

because I have so many these instances

I’m making a flash baton. How do I give it a trigger kinda like a gun that the player presses and it causes damage

[woeful leaf]

What have you tried

[barren kelp]

Okay so I learnt I can use the activate in event thing and that’s the trigger on the XR controller but in order to toggle that off I need code?

[woeful leaf]

What now

[wild vigil]

I have a good idea of what I want to do, just missing a bit of knowledge on the coding side. Would appreciate if I could talk with a skilled coder. Looking at Scriptable Objects and EditorWindow.

[main shuttle]

That one doesn't exist, it's just something that vertx would want 😛

[woeful leaf]

yeaaaaaaaaah

Just realised that

[plucky inlet]

If you got a question about something you tried, feel free. But if you got no code, you at least should come up with a code structure or something, cause noones gonna conceptualise your idea here. especially not in general

Oh yeah that's quite funny actually

[wild vigil]

I have 500+ lines of code

[woeful leaf]

Then follow this

Even if you weren't to have code, still follow that

[wild vigil]

TBH I'm a bit depressed and this project is helping me take my mind off things.

[woeful leaf]

That's still not helpful

[plucky inlet]

Post your code on a paste website, best part only the code part that is necessary for your issue, then people can look at it. You barely will find someone here making a free coding lesson 1:1

I mean it would help if he'd first actually describe his problem

But yes, having the relevant code will also help

Sanity Check:
I need a backend for my game to retrieve and store some data and do some matchmaking, but I do not need any live multiplayer functionality
Surely I can just do this with a plain ol rest api that I host on some azure server, right? Or do we do something completely different in Unity

[woeful leaf]

No, you should be able to do stuff with API's and databases and such

[keen siren]

Just started working on a card game with my brother who's new to Unity and doesn't have any coding experience.

Want to create a smooth workflow where he can create new cards, enemies etc. in the editor.

Currently effects are MonoBehaviors that you add to card prefabs. When a card is played all effects are executed. The most basic effect is a DealDamageEffect that has a "Value" field where you enter the amount.

I'd rather have them be ScriptableObject assets (this would for instance allow me to also have the cards themselves be scriptable objects instead of prefab variants) but this comes with the problem that I would have to create one asset for every value, e.g. "Deal5Damage", "Deal7Damage" etc. (I don't want damage to be entirely based on a character strength or similar).

What's the smoothest way around this problem?

[woeful leaf]

Just a quick question, are you using git?

[modest furnace]

Can someone please help me? I'm getting this error and I can't open my unity project (except in safe mode)
Library\PackageCache\com.unity.test-framework@1.1.31\UnityEngine.TestRunner\NUnitExtensions\Runner\UnityTestExecutionContext.cs(110,16): error CS0246: The type or namespace name 'EnumerableTestState' could not be found (are you missing a using directive or an assembly reference?)

[swift falcon]

Hey does anybody know how I can generate a convex mesh using code in unity?

[woeful leaf]

Don't cross post. #📖┃code-of-conduct

[swift falcon]

When people answer then sure, hard to get help in a constantly moving chat

[woeful leaf]

It's still not allowed

Also it's not even constantly moving, you posted them with a 3 minute gap

Furthermore, it's even still visible on screen

[swift falcon]

Okay

There you go are you happy

It's a question more fit for code general than code begginer anyways

[quaint rock]

also have you googled for it or looked at the asset store

[swift falcon]

I have googled it

Mostly stuff on convex colliders

Google is always where I go first

[quaint rock]

writing a convex hull generator on your own is a non trivial issue, but its also a solved issue

so there will be many libraries and assets for creating convex meshes

[swift falcon]

I may be getting confused with concave geometry

[woeful leaf]

Isn't ProBuilder a decent one? Or am I misunderstanding the context

[swift falcon]

Well I'm trying to build a quake/half-life map loader

I tried generating tris and figured out quickly that the files don't store tri data but apparently data for convex or concave geometry

[quaint rock]

no clue with out little context is given, i normally think have convex hulls being generated for non convex geo for collsions or render purposes

what does a half-life map loader even mean

[swift falcon]

Well

[quaint rock]

half-life just did map loading based on triggers nothing complex

[swift falcon]

It loads a map

From the game half life

[swift falcon]

The actual map files

.map

[quaint rock]

yeah good luck with that

also you mean .bsp

not .map

[swift falcon]

No I mean .map

Jackhammer and trenchbroom and other tools export .map files that I can load in half life

I'm using those files

[quaint rock]

assuming you meant compiled maps

[swift falcon]

Compiled would likely be .bsp yeah but I'm going for .map

Like qodot for godot

[quaint rock]

also just loading a half-life map in unity is not going to be trivial

you will be recreating a lot of wheels

[swift falcon]

Yeah I know

It's something I'm doing for fun lol

And to maybe use in small retro projects

[quaint rock]

not even sure why you would need convex hull generators for that, but you will need to be doing a lot meshes setup in code

[swift falcon]

So I can use hl1 map editors

[swift falcon]

It seems to store convex mesh data, not polygons

[quaint rock]

yeah but you can make polygons from that definition

[modest furnace]

do `` infront and after your code

[woeful leaf]

Just listen to the !code

[main shuttle]

Just follow the thing I posted...

[woeful leaf]

Don't "try to do something else", just adhere to that

[mellow sigil]

and explain more clearly what the issue is, "I've messed up" doesn't tell us anything

[woeful leaf]

It's 3 backticks by the way

```

Well that works too I suppose

Also if you're using VS slap CTRL+K+D on that code

Also you didn't exactly define what the issue is with the sound

[main shuttle]

Why would this even play sound?

[woeful leaf]

Wait it's not even playing sound? (I didn't really look at the code)

[main shuttle]

Why not just add an event to your animation where it calls the step effect function when the animation is putting the foot down?

[woeful leaf]

Did you ?

[main shuttle]

You don't use animations?

Okay, so no 3D model that moves then?

[quaint rock]

just do it based on the velocity of it

play sound every x seconds while velocity in a direction is greater then some threshold

[main shuttle]

Sure, but what Passerby said is a valid solution. Just check the velocity in Update, and check if the last step sound was x milliseconds ago.

[quaint rock]

with that you could even shorten the time as velocity goes up too

each time can cast downwards to get the physics material you are standing over and use that to modify the sound to play and make sure you are infact on the ground

so many ways to do it, just break the problem down into how do you play a sound at a set time interval and how do you detect player movement

I have a cube and I want to Instantiate objects within the bounds of that cube without manually hardcoding the bounds. Is there an easy way to do it?

[calm delta]

how do i put a line renderer between 2 ui objects on the same canvas?

[woeful leaf]

Solution?

[main shuttle]

We gave ideas? You want free handouts from us?

[cyan vector]

Use a UI Line Renderer

https://bitbucket.org/UnityUIExtensions/unity-ui-extensions/wiki/Controls/UILineRenderer

[calm delta]

oh thank you!

[cyan vector]

Create a cube, scale it, then use
Random.Range(-cubeTransform.localScale.x,cubeTransform.localScale.x);
Same for Y and Z.

[calm delta]

@cyan vector how do i get access to the UI Line Renderer?

[buoyant crane]

float someX = Mathf.Clamp(someX, -cubeXScale * .5f, cubeXScale * .5f);

Instantiate(prefab, cubePos + new Vector3(someX, 0, 0), Quaternion.Identity);```
this constrains the x axis of the cube. it won’t take the size of the object you are instantiating though

[cyan vector]

Clone the repo ^^

[calm delta]

got it, never downloaded an extension like this before :P

[jade heart]

Hey everone, I have some problems with an equation calculator that I want to use for creating volumetric clouds. I'm getting 8 compiling errors, all of which correspond to error CS0149. What part did I screw up on coding and how do I fix it?

https://gdl.space/qihaneqoru.cpp

[leaden ice]

nobody memorizes error codes

share your error messages, the full ones

you can start with just the first message.

I will say one thing you've done wrong here is your variable names are completely inscrutable.

[jade heart]

This error repeats but with different lines

[leaden ice]

and the code as you presented it is exactly hwo it was when that error opped up?

[jade heart]

Yes

No changes

[sinful scroll]

is it possible to list the amount of tris being rendered in a scene as a float, if so how can I do it?

[leaden ice]

oh wait I see the problem

You've defined this variable R:
float R = Mathf.Log(l) + ((v - lo) * (hn - l)) / (ho - lo);
But you also have this method above:
float R(float a, float b, float c, float d, float e)

you are trying to then call the method

but you can't, because you've already used that name R for the local variable

the way to fix this is not to reuse the name R for your local variable @jade heart

local variables should not start with uppercase letters by convention anyway

and this is also an opportunity to improve your variable and method names overall, because these single letter ones are very hard to work with.

[main shuttle]

    UnityEditor.UnityStats.triangles
    UnityEditor.UnityStats.vertices

This seems like what you are looking for, that's the same as the stats window.

[sinful scroll]

will these still work when the project is built?

[main shuttle]

No, it's only in the editor.

[jade heart]

Thank you, it works wonders now!

[sinful scroll]

Do you happen to know an alternative which works when the project is built?

[dapper flower]

When should I use static blackboard class to store variables and when should I use a ScriptableObject for the same effect?
Using static blackboard class I need to repopulate on each recompile. In ScriptableObject it seems that it keeps the data, but does it stay the original or it's a copy (after the recompile)?

[main shuttle]

Well you would need to code it yourself then, and that wont be an easy task I think. I would expect some assets on the store to do this for you.

[sinful scroll]

oh alright then, thanks anyways

[leaden ice]

Can you elaborate on what a "static blackboard class" is?

and when you say "store variables" what kind of data are we talking about? What's the intended use and lifecycle for this data?

[dapper flower]

Something I use to, for example, store preferences and, on change, save them to UnityEditor.EditorPrefs class.

[leaden ice]

what kind of preferences?

[dapper flower]

ShowLogs
SaveDuringPlayMode
SaveFolder
...
It's an editor tool

[leaden ice]

and again can you explain what "static blackboard class" means?

[eager pier]

Can someone help me which this if statement. I need to grow a small square. 2D collider logic

[leaden ice]

This is usually stuff you'd store in a ScriptableObject

and use a SettingsProvider

so you'd get a section in Project Settings

[leaden ice]

what kind of help do you need with it

what does "grow a square" mean exactly?

what is this supposed to be doing or checking?

[eager pier]

I have a point ( Vector2 location)

It's returning an array

I can show in-game problem

Right now, it's drawing lines. I need sqaures

Problem is if statement

[dapper flower]

It's a globally accessible class that has some useful value types and reference types. For example, I create the EditorPreferences' class instance that will be stored in UnityEditor.EditorPrefs class. I also have a few constants like DefaultSavePath for a Reset method to use. Classes don't need to know what Blackboard class is, they just need to get the data from it. Its usually what a blackboard class is.

[dapper flower]

Well, for reference types, does it keep the original reference or copies it on a recompile?

[leaden ice]

no

nothing is kept

except for things that are serialized to assets

or something like EditorPrefs

[dapper flower]

So using a static POCO or SO, I'll always need to repopulate?

[leaden ice]

is this writing heightMap data for a Terrain?

[leaden ice]

SOs are serialized/saved as assets in the project

[eager pier]

yes problem is I need to project the players on the chunk

[leaden ice]

wouldn't you want to compaire ranges of values here, instead of exact values?

E.g. instead of u == location.x || u == location.x + 10 shouldn't it be u >= location.x && u < location.x + 10?

Does anyone know a bit about android studio? Is it possible to put an APK or AAB that I get from unity inside of a view in android studio an put buttons etc over that view with android studio? I wanna use AR functionality from Unity but the rest from android studio

[eager pier]

Yes, this is it

[leaden ice]

yes

not quite as an APK/AAB but you can embed a Unity game as a view in an Android app

lemme dig up the docs

Man this shit is buggy

[thin aurora]

I got this basic command class that takes a command with a handler to invoke, but for some reason my handler is not allowed. I expect the Delegate type to allow my method, but I end up with the given error. I can't find anything about Delegate types not being allowed in constructors. What am I doing wrong?

public struct PillowCommand
{
    public PillowCommand(
        string name,
        string description,
        Delegate handler,
        PillowCommandArgument[] arguments,
        PillowCommandParameter[] parameters)
    {
        this.Name = name;
        this.Description = description;
        this.Handler = handler;
        this.Arguments = arguments;
        this.Parameters = parameters;
    }

    public string Name { get; }
    public string Description { get; }
    public Delegate Handler { get; }
    public PillowCommandArgument[] Arguments { get; }
    public PillowCommandParameter[] Parameters { get; }
}

[leaden ice]

You can't use Delegate like that

you should define an actual delegate type

and use that

public delegate void LogHandler(string message, string? prefix);```

[thin aurora]

I don't have a specific type though. I'm not restricting what can be used

The list of parameters can vary

[leaden ice]

how do you know how to call/invoke it then?

Oh I see

you have a list of parameters

[thin aurora]

It's a command system, it's reflection to an extend

[leaden ice]

(what's the difference between Arguments and Parameters?)

[thin aurora]

Parameters are optional, maybe I should rephrase them

I could swear this would work

But apparently not because I can't get it to work on methods now

[leaden ice]

I've never tried to do things this way 🤔

[thin aurora]

I swear this worked before, I have no idea how lol

https://learn.microsoft.com/en-us/dotnet/api/system.commandline.rootcommand .NET seems to just add a million overloads (SetHandler)

[leaden ice]

Should you not just do this the old fashioned way, with an interface or something?

public interface MyDelegate{
  void Run(PillowCommandArgument[] Arguments, PillowCommandParameter[] Parameters);
}```?

[thin aurora]

I suppose

Would love a solution to this though

[late lion]

DynamicInvoke should only be used when absolutely necessary. You have better options, you should those.

[thin aurora]

Which is?

[safe knoll]

it's not too pretty but you can cast it to it's delegate type which will allow it to get through.

    void TakeAFunc(System.Delegate dele)
    {
        dele.DynamicInvoke( ... );
    }

    void AnotherFunc()
    {

    }
    
    void FuncWithInt(int i)
    {

    }

        TakeAFunc((System.Action)AnotherFunc);
        TakeAFunc((System.Action<int>)FuncWithInt);

Also not pretty: Just straight up use reflection. pass the object and function name. Not that a command system cares too much, but one benefit is MethodInfo.Invoke performs better than Delegate.DyanmicInvoke.

[swift falcon]

Singletons work for a single instance. Is there a way to do something similar when multiple objects (so multiple instances) share the same script? I'd want my checkpoint objects to survive the scene reload

[quaint rock]

Singleton is not what makes it survive the scene reload

[potent sleet]

parent checkpoints to the manager and add DDOL

[quaint rock]

you can just DontDestroyOnLoad them or you can just make sure they are memebers of a scene that does not unload

[swift falcon]

Singletons prevent them duplicating on scene reload right?

[swift falcon]

I'll look into what DDOL is thanks

[quaint rock]

depends on the implementation

really what you want is what Null described

hi, i have a player controller script, when player touches the ball; ball position is setting to players forward position.

but i dont have a dribble system. When i run/walk, ball doesnt move and its awful.

how can i make a dribble system like this? "https://youtu.be/-47ak3wYHZs?t=510"

⚠️: if ball is far from player, player shouldnt move

[cedar pivot]

i need really help, im trying to do this over 2 days..

[potent sleet]

ye goodluck with that

pretty complex system like that cant be done in 2 days

unless ur a coding god

[quaint rock]

really would fake it and do it all as a animation

otherwise maybe attack the ball to a target joint on the player

and add force to it once and a while

[swift falcon]

Declare a variable of class CheckPoint (my c# script) in PlayerManager (which handles the scene reload) and add a DDOL(CheckPoint.gameObject)?

I'm asking but I assume it's not that as it broke my scene reload

[quaint rock]

but yeah it will take day or 2 work to make dribbling the ball like that look good and work

[potent sleet]

no

[cedar pivot]

I'll try the animation idea.

but how do I make the player to not be able to rotate before the ball touches the player's foot?

[swift falcon]

I fail to understand what "parent checkpoints to the manager" means

[quaint rock]

checkpoints all have 1 common parent object

[swift falcon]

Oh in the hierarchy

[potent sleet]

in the hierarchy make them all children of 1 checkpoint manager thingy

ddol on the manager

[quaint rock]

that way they can all be managed by it, and that can be set to not be destroyed when a scene loads

[swift falcon]

I'll try that thanks

ok i am playing a game now i will throw the system i tried after the match is over

[wild vigil]

I mean I don't know where I would put a constructor for this Dictionary in a scriptable object...

[hexed pecan]

You would just add the = new(); to your current line static Dictionary<string, List> propertyLists

Hi! I'd like to use mesh.CombineMeshes method to do some batching. But I can't seem to retain any other uvs other than the regular uvs (I need lightmapping uvs as well as uv set 4 but they turn up blank) 😿
Anyone got any ideas?

[proper oyster]

the hasLightmapData option seem to indicate that they do some stuff with the uvs as well....

[worthy scaffold]

yeah I have that active on meshes I combine that use lightmap. And I can see in my shader that its flagged as having lightmaps but the uv data is blank 😦

[proper oyster]

you may have to find a way to do it without unitys help

[worthy scaffold]

do you mean not using the combinemeshes method?

[proper oyster]

yes

[worthy scaffold]

aah I see

Yeah that seems like an option

thanks!

[wild vigil]

How would I link my asset file to my editorwindow?

[barren kelp]

Hi. If I want to change component in script by referencing the “XR Grab Intractable” component and then if I wanted to do something with the interactble event more specifically the activate feature. What would I need to reference in my script would it be interatble events or ActivateEventArgs

[wild vigil]

I mean, I have a ScriptableObject asset file that is working like a permanent database and I would like my EditorWindow to see it and use it.

In the case of a monobehaviour I believe I can just link it directly, but not sure how to go about this with EditroWindow.

[proper oyster]

if you know where it is you could just load it with this
https://docs.unity3d.com/ScriptReference/AssetDatabase.LoadAssetAtPath.html

[wild vigil]

I'll give that a try.

[regal marsh]

So does controller vibration work on a ps5 controller?

in unity i mean

[proper oyster]

i assume you mean the
DualSenseGamepad / controller ?

there is the SetMotorSpeeds function in the input systems code
https://docs.unity.cn/Packages/com.unity.inputsystem@1.2/api/UnityEngine.InputSystem.DualShock.DualSenseGamepadHID.html

[ebon steeple]

I want to create a premade script when clicking an option, sort of like how I can create a new scene when clicking "Scene", but It'd be my own name with my own script. Thanks in advance!

[wary ferry]

Does unity have some system from drawing components created via script to the scene before running? Like if I add a box collider to a sprite programatically at awake can I get it to draw the box collider's gizmo?

[leaden ice]

it will draw the gizmo once the collider exists

if you want it to draw a particular gizmo in scene view you can use OnDrawGizmos() or OnDrawGizmosSelected() and draw whatever you wish

[wary ferry]

anyway to access the box colliders gizmo draw function from the script?

so i dont have to build something manually

[leaden ice]

the box collider doesn't exist yet so that doesn't make sense

There's this https://docs.unity3d.com/ScriptReference/Gizmos.DrawWireCube.html

[wary ferry]

you're right that makes sense

will check it out

[swift falcon]

After trying quite a few things with this, I've not managed to make it work. So far I've declared a Component[] type variable which I plugged in with each checkpoint in the inspector.
In Awake() I have a DDOL for CheckPointManager and I loop through Component[] to DDOL each children gameObject. This still isn't it 😦

[quaint rock]

you do not need to DDOL the childern

only the parent

only mentioned GetComponentsInChildren so you have a easy way to access all of your checkpoints from the manager object

var checkpoints = GetComponentsInChildren<Checkpoint>(); in the checkpoint manager script for example would get you all checkpoint components that are on child objects

[soft shard]

Sounds like your looking for a MenuItem or CreateAssetMenu attribute, depending on what your trying to do:

[eager aspen]

Hi all, I need to implement a star pathfinding in my project. I've never done this before. I've started looking into it and I think I mostly understand it but there's one thing I'm not getting

In my project I'm using it to determine if block A is connected to block b via a chain of other blocks

These blocks can be destroyed in the middle of a chain and I see a potential issue where when I'm walking the grid that when it hits the blank space it's just not going to clear the open list

So how does one go about determining that there is no path when some of the nodes are completely cut off

[leaden ice]

that's exactly the point. If you do the graph traversal and never reach the destination, there is no path

you should also clarify if you're just implementing A* yourself or using the "A* pathfinding project" asset.

[eager aspen]

But how do I determine that I have traversed all of the nodes that I'm capable of if I'm just going off of an open list?

I'm implementing it myself

[leaden ice]

you keep going until your fringe/queue is empty

once it's empty you've traversed everything

[eager aspen]

Right, but if I just pull in all of the blocks and add it to a list then that would contain all of the blocks that I can traverse and all of the ones that are separated

[leaden ice]

why would you do that

[eager aspen]

How else would I do it?

[leaden ice]

that's not how the algorithm works

you put your starting node in the queue

that's it

to start with

then you are only ever adding the neighbors of the current node to the queue

anything that is not reachable from the starting node will naturally never get added.

[eager aspen]

Oh!!

Got it now that makes sense

Thanks so much! I would have been circling that all day

[coral hornet]

how should i go about making a Z axis curve in a 2.5D game? basically i want the player to turn around a curve and have the camera continuously follow them on their path, where the light blue is the cameras position, the blue is the cameras direction its facing, and the black is the players path from a top down perspective

[leaden ice]

use splines

[coral hornet]

ill look it up

[leaden ice]

as for the camera, use Cinemachine

[coral hornet]

wait so can you explain to me how splines work? from what i can tell they are just a 3D representation of Bezier curves, right?

[leaden ice]

have you gotten your IDE configured yet?

[leaden ice]

more or less, sure. They're like a path you can create and then your code can sample the path to get a position and orientation at any point along the curve

you had errors which were not showing before

meaning it was not configured

[somber nacelle]

have you actually started using the Vector3 you assign in OnTriggerStay

sorry to bug you but, is there any article you know of that documents splines for use in monobehavior scripts? im seeing alot of doccumentation for how to use splines in the viewport to make things like curved meshes, but im not seeing alot on how to access their data at runtime.

[somber nacelle]

actually, post the current code in #💻┃code-beginner because you shouldn't have crossposted in the first place since you were already receiving help in that other channel

just because you didn't receive a spoon-fed answer doesn't mean you weren't receiving help

[leaden ice]

Using the SplineAnimate comnponent makes it somewhat easy

hold on

[somber nacelle]

you know it was me that you were interacting with in that channel right? i was the one pointing out your issue
#💻┃code-beginner message

so then what part of that interaction was not receiving any answer or help on the topic you had a question for?

[swift falcon]

I need the objects more than anything. When a checkpoint is hit I destroy its collider so that the play can't "rewind" the level by hitting already-obtained checkpoints. That's why I want all of my checkpoint gameObjects to survive a player death. It saves me a massive headache. It still causes one tho

[somber nacelle]

and we clearly moved past that and i was providing information about your issue. if you wanna just cry about not getting spoon fed help then i'm just going to block you. good luck getting help when you refuse to even cooperate with those actively trying to help you 🤷‍♂️
also nice job editing your message after the fact when you said "i don't know what that means" instead of "it is already configured" 😉

[thick socket]

      tmp.Q<Button>("HeroButtonRenderer").clicked += () => HeroButtonClicked(hero);

    }
    static event HeroButtonClicked(HeroInfo hero)
    {

    }

I know this is very wrong...how would I setup this to be an event?

[somber nacelle]

is HeroButtonClicked supposed to be an event that other objects are subscribing to? or is it just supposed to be a method?

[thick socket]

was hoping it could be both?

[somber nacelle]

that doesn't make sense

[thick socket]

🤔

[somber nacelle]

you can subscribe a method to your event and invoke that event, but the event itself cannot be defined like a method

[thick socket]

hmm ok thanks

I got to go watch a video again

was wanting everytime that function to be called

and event triggered and everyone that subscribed to the event did a different function

[somber nacelle]

i think you should for sure go find a tutorial about events because you appear to have some major misconceptions about what they are and/or how they are defined

[desert shard]

events are epico

[thick socket]

is there a way to attach an event to like a VisualElement (UI Toolkit) the same way I do like Button.clicked?

[somber nacelle]

i haven't used UIToolkit so i have no idea. i imagine that it probably has button-related events though 🤷‍♂️

[thick socket]

basically when 1 button is clicked I want the background of others to turn back to off

figured easiest way was using an event

[somber nacelle]

okay and again, i have not used UIToolkit so consult the docs. i'm sure they are pinned in #🧰┃ui-toolkit

[teal delta]

Hi there, I made an cube and i want it to stay in place and rotate around player (so that It looks at him) could anyone help me get into the right direction?

[leaden ice]

"stay in place" and "rotate around the player" seem like they are at odds with one another

what behavior do you want? You want it to orbit the player?

[teal delta]

Well idk how to say it so that it makes sense

[leaden ice]

draw a picture?

show a video example?

[teal delta]

Yeah will do that

Wait a sex

Sec*

Does this make any sense?

[leaden ice]

so you just want it to look at the player

is this 2D or 3D?

[teal delta]

Yes

2d

[leaden ice]

which one lol

ok so

[rich sleet]

"is this 2D or 3D"
"yes"

[teal delta]

Thats what i meant, rotate in place

[leaden ice]

it's basically just:

void LateUpdate() {
  transform.right = player.position - transform.position;
}```

[teal delta]

I was responding to "so you want it to look at the player" but he typed too fast

[teal delta]

Wait thats it?

[rich sleet]

i know, it was just funny lol

[leaden ice]

that's it

[teal delta]

Thank you : D

[leaden ice]

it might be transform.up instead of right, it kinda depends how your sprite is drawn

[teal delta]

Well, i can always play around it

[tough osprey]

If you were going to have a large area on a 2d grid game that grows trees and then when they get big enough an NPC comes over and chops it down to get wood, would you have the trees and their sprites be Tiles on a Tilemap where you manipulate the tree by modifying Tiles on the Tilemap based on state? Or would you just use a GameObject for each individual tree? Let's say the area may contain 100-200 trees. As I write this out, I'm leaning towards one option, but curious for input anyway.

[leaden ice]

it depends on how the interactions work. Ideally you would not have to use a GameObject

if you can handle all the stuff by inspecting the grid data and doing grid-based pathfinding and grid-based logic, then it can all be in tilemaps

[thick socket]

renderTexture.style.backgroundImage = new StyleBackground(hero.renderTexture);
(throws erros)

Are you able to set RenderTexture in code in UI Toolkit? I'm able to find setting all other types of background except this

[tough osprey]

Thanks, it's a roller coaster in my mind. I was originally thinking that I can do it with Tilemaps, but then I thought that calling an instanced object to keep track of the chopping state and handle dropping the wood and despawning the tree would be nice to have incapsulated in a Tree object, so I was thinking GameObject. But now I'm thinking a Scriptable Object per tree that works with a Tilemap. Partly because I'm going to want to do the same thing for other types like rocks, and those would benefit from RuleTiles for rendering larger structures (and the performance benefit of Tilemap for rendering many instances of these things)

[leaden ice]

I don't think ScriptableObject would be that helpful

but just having basic POCO objects in your own data model in a grid structure would probably work quite well

With the TIlemap as the presentation layer, so to speak

[tough osprey]

haha thanks, I was just realizing ScriptableObject isn't what I want. I misunderstood their purpose, I thought they were a sort of POCO. I read the docs for ScriptableObject and they're very cool (I'm using them for their intended purpose elsewhere without even realizing it). I'm also working with PhotonFusion so I need some NetworkObject with a NetworkBehavior to act as the controller with an internal structure of items for the trees and their state.

[crystal kite]

tyty ill try that out

[vestal crest]

have you ever made UI sytem with state pattern?

i wanna know whats the logic behind handling ui with state pattern

[wild vigil]

How do I link a scriptableobject to a prefab, in a way that when the prefab changes the scriptable object will respond?

[jaunty needle]

Hello guys, so I have planets in a solar system that I can instantiate and they get added to a list but I want them to be destroyed on impact with another planet and remove themselves from the lest. How can I use events to do that or some other method without directly referencing the list?

[whole olive]

why wont this work

[somber nacelle]

too lazy to type all this out again but here: #💻┃code-beginner message

[proper oyster]

https://help.vertx.xyz/programming/common-errors/compiler-errors/cs1612

[jaunty needle]

I'll rephrase this cuz it's not very clear

Basically I have multiple planets that each need to declare an event whenever they die but I don't think I should loop through every single one of them just to listen out

So I was thinking maybe there is a different solution

[proper oyster]

i probably would make the script that hold the list a singelton
then you can call a function on that scrip from the dying planet to let the system know its dying

[jaunty needle]

ooh alrighty

wait how do I make a singleton again

do I have to make the class static for that?

[proper oyster]

you dont
you just have to make sure that a variable that is static is filld with the reference to the object that reperesents the class

[jaunty needle]

alrighty thank you

[jaunty needle]

    {
        bodies.Remove(celBody);
    }

However this is the function

And I can't really make this static

[naive swallow]

Is there any way to define an interface to only apply to MonoBehaviours? So that you can use properties like .transform on the Interface.

[proper oyster]

you might want to look up how singletons work in unity

[jaunty needle]

i do...

[naive swallow]

I can define properties like public Transform transform {get} and it works, but is there a way I can just say "This interface extends from MonoBehaviour so the only things that implement it are also MonoBehaviours"

[jaunty needle]

The problem is the bodies list is always changing

[proper oyster]

as long as you have just object handeling it thats fine

[jaunty needle]

ok

wait so I can make the list static too right?

[proper oyster]

no
again look how singletons work with Monobehaviours in unity

[jaunty needle]

i'm reading an article alright 👍

[swift python]

Hey can anyone help me why i cant build and run my game? i get burst compiler errors. If you know how to export the log of the console maybe its easier for you to check. I tried to google it and they suggest I need a special module for the Universal Windows Platform in my visual studio. I have tried to install said modules repeatedly and also checked and renamed the file so that the editor can find it. but the errors remain unsolved

[jaunty needle]

Ok I'm sorry but I'm sort of confused because here you said "to let the system know its dying" the problem is I need to pass that this specific planet is dead and to remove it from the list

But I just don't know how I can do that...

[leaden ice]

Are you building for UWP?

[swift python]

yea

[leaden ice]

IDK, share your specific errors etc.

[proper oyster]

you could use this to start the code that notyfys the list script on destruction
https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnDestroy.html

[swift python]

is there an easy way to share them? or do i just snippet the console log out of unity

[jaunty needle]

    {
        if(collision.collider.CompareTag("CelestialBody"))
        {
            //BlowUp();
        }
    }

    void BlowUp()
    {
        NBodySimulator.RemoveBody(this);
        Destroy(gameObject);
    }

I already have this so it's fine

[swift python]

this was after i tried to rename a folder that was named "arm64" into "arm" because he kept complaining he couldnt find the link.exe

[jaunty needle]

It's mainly the list doing its job that I'm worried about

Acc it's fine

[naive swallow]

Don't go changing folder names. Other things probably depend on those

[jaunty needle]

I'll just directly reference it

[swift python]

well tbh i just copied it and renamed it so i have two of the same but with different names

[past pier]

Is there any way to achieve a reverse-sphere-cast in Unity? Meaning that the sphere (or any of the geometric casts) needs to completely overlap an collider (not just "nudge" it for example) for it to count as a "hit"?

[naive swallow]

So now you have two identical copies of the same stuff trying to load at once

[swift python]

@naive swallow i mean i was just trying to fix my problem, because he kept saying he cant find it. so i tested that option out. i guess its a bit iffy yea

[leaden ice]

simplest way I can think of is to check if a few key points on the object are all within the sphere

[swift python]

anyone who can help me? 😦 I have the URP

[naive swallow]

Don't copy the folder

[swift python]

i deleted it.

its not helping what you are saying because im back where i was. 0

do i just go ahead and install them all ? i spent last two hours trying to install all of the latest versions

[indigo hound]

Hey there! Is there a way to check if a sprite is currently behind a sprite mask (so when it's being hidden) via code?

[leaden ice]

Maybe a dumb answer but... use Collider2Ds and normal collision detection stuff

[indigo hound]

That actually might work

Thx

[swift python]

to anyone interested. I had to uncheck and check this, to make it work:

thank you anyway!

[wild vigil]

I am editing a dictionary inside a scriptable object from a EditorWindow. When I leave edit mode and enter play mode my dictionary is reset. Why is the scriptable Object not maintaining the changes to its data...

[cosmic rain]

Yep, for burst and il2cpp stuff you need the C++ compiler.

[swift python]

i know and it was there to begin with

but apparently it wasnt enough. had to uncheck it and then check it again

then for some reason he found some other missing components

[steady moat]

How are you serialising your dictionary ? Dictionary is not serialisable by default isnt it ?

[cosmic rain]

Maybe VS installer bug.🤷‍♂️

[quaint rock]

Dictionary is not supported by regular unity serialization

[swift python]

yea probably. i am about to cry honestly. Errors such as that which defies all logic and problem seeking is so frustrating

[cosmic rain]

But you got it solves in the end, right?

[swift python]

yea but now i got the next slap in the face:

[quaint rock]

a work around i sometimes do, is store things in a list of structs where the struct contains my key and value. then later on reconstruct a proper dictionary from that list

[swift python]

Why cant things just work 🌝

[wild vigil]

Thanks. I should have thought of that...

[quaint rock]

https://docs.unity3d.com/ScriptReference/ISerializationCallbackReceiver.html
this provides a good place to do the conversion

[steady moat]

Personally, I do the conversion with Linq (.ToDictionary()) in the Awake

[quaint rock]

awake is not always a option for all types the callback can be nice since it will get recalled if someone edits the list in the inspector

[dusky quest]

i have this class and i want the second constructor to call the code in the first constructor when its done, is that possible?

[quaint rock]

jsut call it by name

oh nvm you need to constructor chain it

[steady moat]

You can do it in OnValidate, if it is something you wish to control. That being said, the ISerializationCallbackReceiver is a more complicated way to do it.

[dusky quest]

doesnt work

[quaint rock]

public Foo(int id) : this(id, "")

[dusky quest]

how do i apply that to my code?

[quaint rock]

public Country(string name, Color color) : this() {

[somber nacelle]

#archived-code-general message

[honest yarrow]

Which one?

Manual or Unity

[somber nacelle]

well did you install visual studio via the unity hub when you installed the unity editor or manually?

[honest yarrow]

Manually

[somber nacelle]

then take a guess at which you should click

[honest yarrow]

Ok

Thanks

[somber nacelle]

once you've got that configured you need to figure out why one (or more) of the objects hit by the overlapcircle do not have a Monsters component

[honest yarrow]

Wait, where do I find this modify option?

[somber nacelle]

in the visual studio installer like the instructions said

[honest yarrow]

But I already have it installed

[somber nacelle]

great! then open the visual studio installer and select the modify option

[honest yarrow]

The monsters component is a script and all the other objects have the script

[somber nacelle]

you wouldn't be getting a NullReferenceException on the line you highlighted if all of the objects on that layer had it 😉

[quaint rock]

arcorrding to your error that is not true

the overlap or what ever you used, captured something that does not have the Monsters component

[honest yarrow]

Ohhh

That makes sense

[somber nacelle]

you should use TryGetComponent, but you'll also want to figure out why something is being detected by that query that shouldn't be

[quaint rock]

you can either make sure with your layermask it only hits things with the component, or you can simple check for null and return early or use TryGetComponent

[broken light]

is there a way to convert a string input to a type ?

so say the field has "int" then i can convert this to a type so i can make say an array int[]

i need this for an editor tool where it can generate an array of a custom type the user decides

[quaint rock]

got a example of the string

got stuff like int.Parse that can take a string and make it a single int

[broken light]

its a field in the inspector of type string so the user could put MyCustomClass

or any other type

then i would want MyCustomClass[]

[quaint rock]

this is very much sounding like a xy problem

[broken light]

a what

which part are you confused by ?

[somber nacelle]

https://xyproblem.info/

[broken light]

ok ill explain the scenario

i have a map editor tool and users can create their own custom tile class

the editor then needs to be able generate array data of their custom class

so right now my idea to solve this is to use a string input of the name of their class

and the editor tool will use that to create the array of the type

they arent GOs or prefabs so i can't reference it

[quaint rock]

so approaching this with strings is asking for trouble

[broken light]

so how do i approach it

[quaint rock]

why cant the user custom tiles just be extending a existing type and override methods of it

[honest yarrow]

would I use
if (attackPoint == null)
return;

[quaint rock]

or just be types implementing a interface

[broken light]

because it might need to set data in the derived type

which isnt part of the interface

[quaint rock]

if its a user type, how do you expect to access data on it, of types and names you do not know about

[broken light]

also intefaces dont show in inspector

which is a pain

[broken light]

because once you convert the string to the actual type it'll have access to its methods

[quaint rock]

making the user extend a existing type you control lets you still be able to store it in a knowen type, and still be able to know about and call methods on it while letting the user override parts of it

[broken light]

hmm i guess but then i either have to force the data to be an array of monobehaviour derived classes , or non monobehaviour dervied classes or structs and the user has no choice in the matter

i can see a situation where i dont want monobehaviour but also scenarios where i do for other setups

[quaint rock]

if you really want to push forward you can just use reflection to do it. but i highly would discourage it

since it makes using it on the other end so much harder, since you would know nothing about the type the user is providing

[honest yarrow]

could you help me out again?

[somber nacelle]

https://dontasktoask.com/

[honest yarrow]

would I use this to only hit the objects with Monsters components
if (attackPoint == null)
return;

[somber nacelle]

well ideally your layermask should be set up to only detect objects with that component, otherwise use TryGetComponent to determine if an object has that component on it

[honest yarrow]

How would I use TryGetComponent, I've only used getcomponent so far

[somber nacelle]

https://docs.unity3d.com/ScriptReference/Component.TryGetComponent.html

[honest yarrow]

I still need help, would this be the code I would use?
if (TryGetComponent(out Collider2D Monsters))
{
TakeDamage(attackDamage) = true;
}

[quaint rock]

if (TryGetComponent(out Monsters monsters)

[somber nacelle]

TakeDamage(attackDamage) = true; also makes no sense

[quaint rock]

then the component it got would be in the monsters variable so you can
monsters.TakeDamage(attackDamage)

[honest yarrow]

It still doesn't work, I get the same error and I'm using the code same code

Same error message

[somber nacelle]

Show the full error message including stack trace as well as the relevant code

[honest yarrow]

That's the error messa

Message

That shows up in console

[somber nacelle]

And the code?

[honest yarrow]

if (TryGetComponent(out Monsters monsters))
{
monsters.TakeDamage(attackDamage);
}

[somber nacelle]

Well none of that could give a NRE, but you're also calling TryGetComponent on this object instead of the object from the array

Make sure to call it on the correct object then save the code and try it again

If it still errors post the full class using a bit site from #854851968446365696

[honest yarrow]

So where would I add the name of object in this code?

[somber nacelle]

call TryGetComponent on the object from your foreach which i believe was called enemy

[honest yarrow]

It still doesn't work

Same error

[somber nacelle]

show the full class using a bin site

[honest yarrow]

There is also an underline under the enemy part

[somber nacelle]

well then your code didn't compile and you shouldn't even be able to enter play mode

if it's a red underline, that is

in fact, if that is the case and you've actually saved your code then you should have a whole new error in the console

[honest yarrow]

I can't enter play mode now

When I used enemy

[somber nacelle]

well since i'm not psychic why don't you share the code like i've asked and also the error message

[honest yarrow]

if (TryGetComponent(out enemy Monsters))
{
Monsters.TakeDamage(attackDamage);
}

[somber nacelle]

why did you swap out the component type for enemy?

you should be calling TryGetComponent on enemy using the . operator

[honest yarrow]

How do I change that, sorry I'm really confused now

[somber nacelle]

do you know how to call a method on an object?

if you are not sure, take a look at this code where you were calling GetComponent on enemy
#archived-code-general message

[honest yarrow]

so should my code be like this?
if (enemy.TryGetComponent(out Monsters monsters))
{
monsters.TakeDamage(attackDamage);
}

[somber nacelle]

yes

When im buildin the game i get this error
“Create visual studio code”
But i have legit no clue what to do about it 🤭

Then i create it with that visual studio code and tadaa even more confusion 😂

[somber nacelle]

make sure you're looking at the first error in the console. you're also not really providing enough information to know wtf you are talking about

[dapper vigil]

I will share tomorrow, time to head to bed for now

[somber nacelle]

make sure you actually save the code. you don't even have an Update method in this class

[quaint rock]

the stack is not from the code you posted

[honest yarrow]

I have saved the code and I changed the fixed update to update, nothing happens

Same error

[somber nacelle]

then you're looking at the completely wrong file

double click the error in the console and it will take you to the correct code

[quaint rock]

the error you gave us is saying there is a NRE on a line with no code, and references a method that does not exist

[honest yarrow]

Oh

I fixed it

It works now

Thank you so much guys

[somber nacelle]

by the way, i did a bit of googling and it turns out you need to read your error messages better. your error is because you are trying to build directly into the project folder. you need to build to an empty folder

[velvet elk]

public class Billboard : MonoBehaviour
{
    [SerializeField] Camera cam;

    void Update()
    {
        if(cam == null)
            cam = GameObject.Find("PlayerCamera").GetComponent<Camera>();

        if(cam == null)
            return;
        
        transform.LookAt(cam.transform);
        transform.Rotate(Vector3.up * 180);
    }
}

im following a tutorial for a multiplayer game and this script that finds a player's camera and looks at it returns the NullReferenceException error on the GameObject.Find line

how can i fix this?

[somber nacelle]

that means there was no object found with the name "PlayerCamera"

also you know you can use Camera.main to get the camera tagged with the MainCamera tag without needing to use any of the Find methods, right?

[sharp oracle]

"This function only returns active GameObjects. If no GameObject with name can be found, null is returned"

[somber nacelle]

to add onto this: whenever you spawn a networked player, you should destroy or disable any components/objects that are not needed by the local player so that you don't have to worry about accidentally referencing the wrong player's object

[wispy grail]

how could i send i close request? there really isnt any clear definition

i think i found it thanks for the help

[wispy wolf]

I've been trying to wrangle the UI system for a bit and I thought I had it figured out. I have a segmented meter and I'm creating the segment nodes in Awake() like this:

nodes = new Image[max];
for (int i = 0; i < max; i++)
{
    GameObject node = new GameObject($"BarNode.{i}", typeof(Image));
    node.transform.SetParent(transform);

    Vector3 offsetPosition = Vector3.zero;
    offsetPosition.x += anchorSprite.rect.x + ((i + 1) * nodeSpacing) + (i * nodeSpriteWidth);

    node.GetComponent<RectTransform>().anchoredPosition = offsetPosition;

    nodes[i] = node.GetComponent<Image>();
    nodes[i].sprite = onSprite;
}

The problem is that the node ends up with an arbitrary Z position, some arbitrary scale, -10 rotation on the X (wtf?).

[wispy grail]

try setting the parent when you create the node and not after

[wispy wolf]

That works if I make a prefab to instantiate. I was kind of hoping to avoid that, but so it goes.

[wispy grail]

i found that if you create a ui element and parent after it causes a bunch of positional errors. weird bug

[deep willow]

why whenever i open visual studio, i have to go into preferences and set it as the IDE i want to use as a default ?

how do i keep it as default

[wanton obsidian]

So, Im making a multiplayer game and trying to get an interaction script to sync door opening and closing however when the Client interacts it works and does the correct opening and closing animations but when a client opens the door the Host sees the opposite animation.
When the client opens/closes the door, the host will see the opposite animation. If the door is open for the host and the client interacts the door will jerk closed then play the open animation and reverse if the host sees it closed

[potent sleet]

Select it inside unity

i did but everytime i try opening it when i reopen unity, it switches back

I was using a dictionary in a Scriptable Object, only to find that dictionaries are not serializable. How would I achieve the same key value setup using lists?

[rain minnow]

there are free resources online to serialize a dictionary to view and use from the inspector, but you can have two lists: one for the keys, and the other for the values. when you add an item to the 'key' list, add the value to the 'value' list . . .

[round creek]

hello, i would like to create a leaderboard for a small game i have; how should i go about doing this?

[rain minnow]

tons of tutorials to start from on google and youtube . . .

[wild vigil]

If my key was a name, and my value was an address, how would I use the key in this case to retrieve the address?

[rain minnow]

since it's a list, you need to get the index of the key (from the 'key' list), then use the returned index to access the value (from the 'value' list) . . .

[wild vigil]

Great, I'll have a look. Thanks.

[rain minnow]

using the serializable dictionary seems like the easier route though . . .

[wild vigil]

My initial idea was to place the Key and Value into a struct. Would this work?

I would prefer to work within standard libraries

[rain minnow]

you can have a list of structs with a key/value, but then you have to use Find with a predicate to search and retrieve the struct based on its key field . . .

[rain minnow]

it's just one or two scripts that are easy to use, that's up to you though . . .

[wild vigil]

how would I run that search on the key field?

int index = listAddresses.FindIndex(x => x.key == prefab.name);

[rain minnow]

no reason to use FindIndex if you have a struct (with key/value), just return the element . . .

[wild vigil]

int index = listAddresses.FindIndex(x => x.key == prefab.name);
AssetDatabase.DeleteAsset(listAddresses[index].address);
propertyLists.Remove(propertyLists[index]); 
listAddresses.Remove(listAddresses[index]);

I'm using the prefab name as the key

[rain minnow]

problem is, you need to manually search for duplicate keys. if you have any, it'll return the first one found . . .

[wild vigil]

would someone have 2 prefabs with identical names in a project?

[full scaffold]

what are you trying to do

[wild vigil]

I'll leave it broken for now.

I was trying to store a dictionary in a scriptableobject...

[rain minnow]

i dunno, it's your project. you need to check for all cases . . .

[uncut mason]

Hey! I'm trying to display debuff sprites in my project but im running into an issue. I need the debuff sprites to move based on the number of them, so if there's one debuff it should be at local 0,0 but if there's 2 they need to both move to the cumulative position is centered as well, and 3 be centered etc etc.. How would I do that?

[wild vigil]

I think I'll check when someone adds to the list - and only allow a new entry if it does not match an existing.

[rain minnow]

place them in a horizontal layout group with the a center alignment . . .

[uncut mason]

oh my god why was i adding them as Gameobjects with spriterenders. i might be mentally deficient

thanks

[wild vigil]

Are lists serializable in ScriptableObjects?

I've switched to lists and they still not being stored.

So you cant serialize structs. Good to know

[gritty birch]

Is there a downside to using a public variable with a private setter, beyond not being able to use the [Range(0,1)] etc things?

[field: SerializeField]
public float someValue {get; private set;}

[SerializeField]
private float someOtherValue;

It seems to work, but I don't know if it comes with downsides I don't know of, or is against a recommended standard, or something of that sort.

[pine spire]

@bitter hound what’s the purpose of float being public? Inheritance?

[bitter hound]

Other scripts can read the value but not change it

[pine spire]

Have public getter and private settet

[bitter hound]

That's what it does, yes

I assume it's mostly identical to

[SerializeField]
float _someValue;
public someValue {
  get { return _somevalue;  }
}

[pine spire]

@bitter hound I assume this pattern is totally fine, though I would doublecheck if changing it is actually outside scope of other classes

[bitter hound]

I've checked and it seems to work so far, but I've been an artist that sometimes codes before, and now I'm looking to transition into being a programmer, so I want to make fewer guesses based on "it seems to work" now. 😄

[pine spire]

I have personally only used private setter and public getter similar to this way

[thin aurora]

Range should also work if you specify field: before it. Right now the behaviour of your field and property are basically the same, other than that the property can be read by others outside the class.

If you have no need to read it outside the class, you might aswell make it a private field

[bitter hound]

Alright, I hadn't noticed that `field:`` makes the other... uh, property modifiers work

[thin aurora]

Your property is just a wrapper for a backing field right now, same as any other field, so there is not much use to it if you don't actually make use of the features of the property

[bitter hound]

and a private field would be private float someValue {get; set;} right?

[thin aurora]

That's a private property

private float _someValue; is a private field

[bitter hound]

In that case I don't know the difference between a field and a property

[thin aurora]

{ get; set; } indicates the getter and setter of a property

You can modify the way you get / set its backing field

[bitter hound]

Previously I've just called all of these 'variables', it seems like I have some reading to do

[thin aurora]

So in your case here, only the setter is private, and the getter is public

[bitter hound]

Yeah, I get that part

[thin aurora]

A property is not a variable

A variable can be many things

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/language-specification/variables

I suppose this is a nice read too: https://learn.microsoft.com/en-us/dotnet/visual-basic/programming-guide/language-features/procedures/differences-between-properties-and-variables

[bitter hound]

I found this:

Avoiding Overuse of Property Getters and Setters

Most people don't realize that property getters and setters are similar to methods when it comes to overhead; it's mainly syntax that differentiates them. A non-virtual property getter or setter that contains no instructions other than the field access will be inlined by the compiler, but in many other cases, this isn't possible. You should carefully consider your use of properties; from inside a class, access fields directly (if possible), and never blindly call properties repeatedly without storing the value in a variable. All that said, this doesn't mean that you should use public fields!

Source: http://dotnet.sys-con.com/node/46342

https://stackoverflow.com/questions/2166433/why-ever-use-fields-instead-of-properties

It seems to imply that in some cases properties can be a bit slower?

[tough aurora]

hello, i am trying to call a: yield return StartCoroutine(exampleCoroutine()); (inside a coroutine)
but the problem is that the coroutine has a for loop and is not looping correctly

i am not sure what the problem is, but i suspect it may have something to do with the code being paused per frame

[thin aurora]

Little to no change performance wise, really. If you only use a class privately, use a private field. Otherwise consider using a property in some way.

It is actually a violation to use public fields

[pine spire]

Properties are basically a conventional format for get and set functions. In C# it is generally considered good practice to use them instead of public fields. Real differences start when you use them to verify if input and output are correct. And nothing stops getter from being more complex than just return value.

[tough aurora]

this is the code

[thin aurora]

I like to reference Stylecop on coding styles: https://github.com/DotNetAnalyzers/StyleCopAnalyzers/blob/master/documentation/SA1401.md

[thin aurora]

IMO properties should only be used to specify how to set a value, be it private, init, or by constructor. Any complex behaviour to set the property should be done in a seperate method altogether, no matter how small

[mental rover]

looks like you're starting multiple coroutines

[tough aurora]

yeah, im trying to code a little cutscene

[mental rover]

so where are you starting them

[tough aurora]

in a coroutine which calls a coroutine after the next

public IEnumerator cutscene(){
yield return new WaitForSeconds(3f);
yield return StartCoroutine(FadeTo(1, 3.5f, sprite1));
StartCoroutine(runText("presents", presentsText, .2f));
yield return StartCoroutine(FadeTo(1, 5, sprite2));
yield return new WaitForSeconds(5f);
}

[pine spire]

@thin aurora yeah I don’t personally use them for anything beyond checking if it’s suitable value, but for example microsoft’s own documentation has some examples I would consider ”complex behavior” https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[mental rover]

and where do you call cutscene?

[tough aurora]

on a trigger enter

[mellow sigil]

Don't use StartCoroutine if you want to wait for the other coroutines to finish. Just yield return FadeTo()

[mental rover]

you can add a debug log for when the cutscene is called - you will likely find it's being called twice

[tough aurora]

ok

[tough aurora]

is there any way to solve it being called twice?, i've also changed the code to what @mellow sigil told me

i've tested it and the same thing happens

[mellow sigil]

Don't call it twice

you have to find where you do that

[mental rover]

verify that is happening first, don't just assume

[tough aurora]

right

[mental rover]

if that is the case though, an easy way is to add a bool, e.g isPlaying, that is set to true when it starts, and false when it ends - then only start the coroutine if isPlaying is false

[wild bane]

guys, if we plan to make some online multiplayer
do we still need the playerprefs ?

for each client

[tough aurora]

ok, u were right, gonna do as u say

[mellow sigil]

Question makes no sense, why would you need playerprefs for anything?

although if it's being called twice when it should only be called once it's better to fix the root cause instead of patching it

[tough aurora]

what do you mean by fixing the root? also, i did what deynai suggested

should i disable the collider component?

[mental rover]

yeah, though since it's calling twice in OnTriggerEnter that's a can of worms to consider, and the fix is likely similar

[tough aurora]

also it works now btw

[mellow sigil]

I mean if it's being called more than you expect then there's a problem that you're just covering up

[tough aurora]

hmm, so is this to do with the collider trigger component or something else? the only elements in this situation that i can think of are just the trigger collider and the player going into it

[mental rover]

debug logs are your friend

[tough aurora]

ok

maybe its because i have multiple colliders on my player

but i think your fix should be ok

[thin aurora]

Yeah I would not even do that in properties. I expect a method for these things. A property just makes a mess, especially when you introduce any complexity in the form of asynchronous code or setting multiple properties in one transaction

I'm not sure if I ever want to introduce any sort of guard clause to them. I can understand if you add those, but right now I would rather put those in a method too.

ComputeBuffer.SetData requires a non nullable data type. I was using a struct. Struct can not be serialized in a scriptable object. What is the correct way to proceed?

[neat lagoon]

what do you mean struct can not be serialized in scriptable object?

are you using the [Serializable] attribute on the struct and making sure the field itself is serializable? for example with [SerializeField]

[wild vigil]

is a 4x4matrix serializable?

[neat lagoon]

yes actually

[wild vigil]

    public struct MeshProperties
    {
        public Matrix4x4 mat;
        public Vector4 color;

    }

[neat lagoon]

yes mark your MeshProperties struct with the [Serializable] attribute

[wild vigil]

will [SerializeField] work?

[neat lagoon]

that is for the field, let me show

[Serializable]
public struct MeshProperties
{
  public Matrix4x4 mat;
  public Vector4 color;
}

public sealed class MyScriptableObject : ScriptableObject
{
  [SerializeField] private MeshProperties m_meshProperties;
}

if you make the field in the scriptableobject public, you don't need SerializeField

[wild vigil]

why is Serializable not available for me...

[neat lagoon]

requires System namespace

using System;

do you know how to include namespaces?

[wild vigil]

I could literally kiss you right now

Thank you. Thank you. Thank you.

Anybody know how to fix this prefab being all jumbled when i try to edit it?

it aligns perfectly when i instantiate it, but not when im editing it

might be because it doesn't know how to align until it becomes a child of a grid layout?

i aligned it to the grid layout then made it into a prefab

[narrow summit]

I think the automated canvas is the problem

And it defaults to the resolution of the game view

@deep willow ^

[deep willow]

how do i solve it? lol

[narrow summit]

Change the resolution of your game view

Or usually, I just edit in the scene honestly, and then apply it back to prefab

not sure what you mean

edit the scene?

Guys how do I change a variable of a prefab as soon as it's instantiated because there is this flickering when I instantiate this planet

    {
        Vector2 spawnPos = cam.ScreenToWorldPoint(Input.mousePosition);
        GameObject planet = Instantiate(planetPrefab, spawnPos, Quaternion.identity);
        planet.GetComponent<CelestialBody>().radius = 0.1f;
        CelestialBody celBod = planet.GetComponent<CelestialBody>();
        AddBody?.Invoke(celBod);
    }

It starts out as radius = 1 but then flicks back to 0.1f

ok i fixed it

[atomic wasp]

Hi, I'm working on a script that changes vertex colors on a skinned mesh instance. It works, but for some reason when I copy from SkinnedMeshRenderer.sharedMesh to an instanced mesh it replaces the source sharedMesh in project assets as well. This is documented in the API reference, though it doesn't say why it is so or how to work around it. Is there a way of working only on an instance of a skinned mesh and not the source asset? Short of constructing a new mesh piece by piece in code.

[teal delta]

hi there, why doesn't this add force to my 2d object? (i checked with console.WriteLine and it finds gameobject with tag and also the object has rigidbody)

[main shuttle]

Is the rigidbody kinematic? If so, it doesn't simulate physics then.

[teal delta]

its not, i just set the gravity scale to 0

but i have the same on player and i can add force to it just fine

[main shuttle]

That doesn't matter. You are sure that the AddForce gets called?
If so, show a screenshot of your RigidBody2D component.

[teal delta]

i dont think thats its added because the ball doesnt move, thats what im trying to figure out. Why doesn't it add

thats my setup for ball

[main shuttle]

Do you have multiple ball objects perhaps?

[teal delta]

nope, just one with tag ball

[main shuttle]

Then add a debug.log in your update, and in your if.

[teal delta]

will do

[hasty canopy]

Transform.forward will send it to z axis

There's your culprit

[teal delta]

ohh

didnt think of that becasue i ususally do 3d games

[hasty canopy]

Happens lol, but do optimize your code tho

[teal delta]

yeah it works now

[hasty canopy]

Doing findobject in update is very performance extensive

[teal delta]

will do, its a mess for testing

[hasty canopy]

Cool

[teal delta]

yteah i know its better to do it in update

[hasty canopy]

I believe you meant to say Awake?

[teal delta]

whats the diffrence?

[main shuttle]

Just serialize it...

[hasty canopy]

Very big

[teal delta]

i think both do something once on start

[hasty canopy]

Update does it continuously every single frame

[main shuttle]

Finding at all is bad practice.

[teal delta]

i meant diffrence between start and update

[hasty canopy]

So if your computer has 120 fps, it will find an object 120 times from your heirarchy

[hasty canopy]

Still very big

Start is called only once

[teal delta]

and awake?

[hasty canopy]

Also once but before start

[teal delta]

so its just a little bit faster

and thats the main diffrence?

[hasty canopy]

Between start and awake, yeah, but start won't be called if the script is disabled while awake will (if the gameobject is enabled)

There's an entire execution order

[teal delta]

ohh, i didnt know that

the more you know i guess

tmp.Q<Button>("ItemButton").style.backgroundColor;```

that background color

hmm

might just be easier to have everything in a dictionary

[plucky inlet]

colorList.Sort((col1,col2)=>col1.AllColorValuesAdded().CompareTo(col2.AllColorValuesAdded()));

Something like that?

[thick socket]

probably? not entirely sure and Im terrible at sorts...at this point its probably easiest if I change make another class to store a few things in to make it easier to sort

[plucky inlet]

You can just test it 😄

[cinder ether]

Hello, how can I separate game input from UI input ? For example, when I click on a button, my script from a totally different game object also recognizes the click

[thick socket]

would require quite a few tweaks to work with ui toolkit since I don't have a reference to the item I want to sort at the time I try to sort lol

[plucky inlet]

😄 So you gotta grab the reference before doing so

[thick socket]

much too complex for my smol brain 😄

List<StoreItemsVE> SortedList = itemsList.OrderByDescending(o => o.itemRarity).ToList();

how could I add in like a secondary sort? (this "should" work for sorting by rarity)

ex) I want them to sort by ItemType, then secondary sort by ItemRarity

[thin aurora]

Orderby().ThenBy()

[thick socket]

fantastic thanks!

[thin aurora]

Tip: googling a specific question about something most likely gives you the answer, since many people before you probably wondered this

Source: My answer was a 5 second google search

[thick socket]

fair enough thanks, I was struggling getting search results for sorts that was helpful earlier so assumed wrong

alright here is an actual one I can't figure out from google

[thin aurora]

First link worked for me 🙃

Not to bash of course, googling is a very good skill to have

[thick socket]

inside of a sort, I have an enum I want to sort by...how can I chose the "order" of high to low items?
alright here is an actual one I can't figure out from google

public enum ItemType
    {
    Undefined,
    Currency,
    Loot,
    Material,
    Supply,
        Recipe,
    Weapon,
    Armor,
    Helmet,
    Shield,
    Jewelry,
        Backpack,
        Coupon
    }

if I wanted a different way to sort this enum how could I do that?

aka I want recipe, then weapon, then supply as the sort order for example

[plucky inlet]

you can assign an int to enums so Undefined = 0

[thin aurora]

You manually specify it? I'm not sure what you mean

It sounds very specific

[mental rover]

enums are just ints

[thick socket]

like chose the order in which it sorts by

[thin aurora]

An enum is just a list of numbers so if you use Enum.GetValues you get a list of them

[thick socket]

makes sense...assume I can't change the enum itself

(enum is from an asset and could really mess up asset code if I change values)

[plucky inlet]

As soon as you change the enum and did not specify a position in the enum, it will mess up all your inspector values

[mental rover]

what you could do is create a wrapper that associates a secondary sorting priority value for each, then sort by that value - though that will be something extra you'll need to maintain

just a static dict that maps enum to another value, say

[plucky inlet]

Or just use the NAME plus an INT to be able to sort the enum by name but still got its correct int to call on

[thick socket]

sweet thanks guys 🙂

last question...hopefully

why can't I set my itemsList to the new SortedList?

[plucky inlet]

cause you assign a type to a List

[mental rover]

it is outside of the scope

[plucky inlet]

itemList is a list of whatever type and SortedList is a type of the namespace Collections

And that 😄 outside of scope too, I would not call it uppercase sortedList tho, cause it seems to be already a thing in collections

[thick socket]

ah gotcha...renamed SortedList to sortedList

and now its fixed 😭

didn't know SortedList was a keyword(also just stole the code from stackOverflow)

[plucky inlet]

yeah, bad habit, abandon this! 😄 copy paste without thought will get you 0 knowledge

[thick socket]

I mean, I understood the code, just didnt realize the variable name they chose was bad lol

anyway, thanks everyone!

sorts was my most hated things from my coding classes like 4y ago lol

[reef peak]

i just shoot it towards the ball

[warped condor]

If anyone has time to help could you please DM me so I can send you the details of my problem since my issue seems to be a bit complex to post here. Put simply though I'm having trouble updating a object to match a target position exactly each frame using unity's physics, without causing jitter and also any objects that have a hinge joint component freak out and jitter a lot when interacted with even though I'm using methods such as Rigidbody.MovePosition and MoveRotation

[plucky inlet]

Feel free to open up a thread and explain to everyone here, so we can look into this.

[leaden ice]

(and pick one channel, you xposted to physics)

[warped condor]

Ok thanks, will do. How can I open up a thread and is it expectable to show multiple sections of code as I don't want to flood the thread?

[leaden ice]

It'll be your thread

you can flood it all you want

Post code as per

[fiery oracle]

does anyone have experience with building large open world games? wondering how do i manage terrain chunks for performance

i am considering activating terrains around the player on a 3 x 3 grid:

with each terrain tile being 512 x 512, will this be too large for optimization purposes?

(i am also using culling)

[leaden ice]

you can only find this out by testing/profiling it on your target hardware

every game is different

[fiery oracle]

right, are there other approaches I can explore?

[leaden ice]

approaches to what?

Profiling?

Or what?

[fiery oracle]

terrain streaming

[leaden ice]

Other approaches besides terrain streaming?

Not sure I understand

[fiery oracle]

approach to terrain streaming

[leaden ice]

you haven't really described any approach

you just said you'd keep 3x3 loaded

[fiery oracle]

right, that's one approach

tiles are activated as the player moves around

would love to hear how someone who built an open world game handled this

[leaden ice]

that approach is what terrain streaming is

[fiery oracle]

okay, thank you

I’m working on Lag Compensation and I ran into a problem. On the server I instantiate a “RewindHitbox” game object and then immediately shoot a Raycast. But the problem is apparently at least one FixedUpdate needs to run for a raycast to hit a newly moved object.

[potent sleet]

They do "portals" when to activate terrain relevant to player @fiery oracle

[fiery oracle]

i actually am watching that talk now! i've seen that talk years ago too

Hello, trying to make a camera for my character. Work well in first person , but in third person the camera does not orbitate or stays in the back of my player. Not sure how to do it.

    public void Look(Vector2 lookDirection)
    {
        // Convert mouse input to rotation
        float mouseX = lookDirection.x * Time.deltaTime * sensX;
        float mouseY = lookDirection.y * Time.deltaTime * sensY;
        yRotation += mouseX;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -45, 45f);

        // Rotate camera
        transform.rotation = Quaternion.Euler(xRotation, yRotation, 0f);

        // Rotate Player
        playerOrientation.rotation = Quaternion.Euler(0, yRotation, 0);
    }
