Probably because KeyValuePair can not be serialized

[tired drift]

hm

guess i'll have to transform it manually

[thin aurora]

Or make a custom editor for it

Or for a dictionary in general

[tired drift]

will do later on, just didn't want the hassle rn cuz i wanted to check it out really quick

but ty

[brave lintel]

Hello everyone, I have a quick question. In my scene, I have a public class called GameAdmin, which stores critical game data and variables. When I instantiate different players, I have to access the GameAdmin by using FindGameObject or FindObjectWithTag commands. It is getting heavier while having more objects trying to get data from GameAdmin. Is there anyway to achieve this by using something else like static methods?

[thin aurora]

Sounds like you might want to apply the singleton pattern to it.

https://gamedev.stackexchange.com/a/116010

Something like that

Then you can access it using GameAdmin.Instance

Note this only works if you are sure to only have a single GameAdmin

[brave lintel]

Yeah, I want only one of them

[thin aurora]

If you want to really make it look good, you should implement a sort of dependency collection where you get it from, instead of having each manager have their own Instance. Then you grab it from that collection, or allow it to make a new one if it does not exist. This is how Dependency Injection works in C#

But as a quick fix, having it implemented in the behaviour itself works

[brave lintel]

I have many dependencies and cached objects, variables in the GameAdmin. If I do it static, I would not be able to use its instance in the scene?

[thin aurora]

Yes

Just know that if your scene unloads, the singleton object no longer exists, but the reference does. So be careful with it

You could add an OnDestroy method and set Instance to null, but this gives edge cases where it might not exist so honestly you should just make it persist between scenes and clean it up properly when you need it to.

[brave lintel]

Thank you, I will check the link and try to implement

[olive shore]

anyone know how to fix this?

[Collab] Collab service is deprecated and has been replaced with PlasticSCM

[somber nacelle]

stop using collab and use unity Version Control (formerly called PlasticSCM)

or switch to git. either way, it's been more than a year since collab was shutdown

[olive shore]

my version control is 2.0.3 tho

[olive shore]

fixed it, just turned off collab 🤷‍♂️

[urban marsh]

Hello everyone !
I am currently working on a part of the UI for my game : displaying skill trees.
As these are randomly generated, I am currently creating a script that will draw the skill tree for the user when needed.
I have already done the part where I decide which skill goes where (pixel-wise), and I have created a list of "skills" (using an interface so I can easily grab their icons and names and stuff), and a list of coordinates (Vector2) where I want them in my tree.
now, on to the real "drawing" part :
I have my "container" where I want to create my prefabs.
should I just instantiate them inside it (with the container as parent transform) like I would to with units/enemies/projectiles in the game world, or is there a UI-specific way to do it ?

[latent latch]

You wouldnt instantiate the skill as a gameobject if that's what you're asking. Your container should have a script that contains a reference to the data of the skill, and information to display such as the sprite which you can put on the skill tree.

[urban marsh]

what do you mean ?

I should have "already created" empty skills in the container, ready to be filled and moved when changing the tree to display a new skill tree ?

[latent latch]

Your container, the visible part is displayed as a rect, right? You'd send a raycast or however you want to select to that gameobject which will contain some script such as a 'Slot'. This slot should contain the data (to instantiate into the scene) of your skill which you can then retrieve it from.

[urban marsh]

I didn't understand a thing you said :/

[latent latch]

Using the UI and canvas is usually the way to handle such things if you're interested in that method.

But since it looks like you're doing 2D I'm pretty sure you can handle it in a similar way.

[thick bough]

They're asking how to do it in UI though

Yes you would just instantiate an object like you do regular transforms @urban marsh, however an additional layer of complexity with UI is how RectTransformss are anchored to the screen, so it depends on canvas scale, aspect ratio and more

[urban marsh]

thanks for the help and the comment about using rectTransform and the anchors : I was wondering why my things where offset weirdly 😄

the docs do say that this stuff is advanced, so perhaps this question is better suited to #archived-code-advanced? (but if I move it there the mods might kill me for cross posting)

Not an error, but a warning

Click the message and it shows you the missing script. Replace it with the correct script

You probably renamed it so Unity has no reference to it anymore

[pseudo zodiac]

@potent sleetI have another question about my quest system if you don't mind.
Basically, I have implemented the system as you suggested but I have a problem: I have my Quest in a list in my QuestManager, however these can't be MonoBehavior and so I can't for example do my onLoadScene function(which is called by my QuestManager) with calls like FindObjectOfType<> or GetComponent<> inside. What am I doing wrong?

[rustic ember]

Is it faster to write cs myInt2 = myInt + myInt than cs myInt2 = myInt * 2 ? Or does the compiler fix it? Or does it just not make a difference?

[cosmic rain]

The compiler would probably optimize the multiplication to addition.

[simple egret]

Yep, exact same on output machine code

[cosmic rain]

Either way, it's not something you should even be bothered about.

[simple egret]

Indeed, there's no significant difference. Try catching bigger performance hogs like repeated uses of Find and GetComponent

[thin aurora]

No difference

[rustic ember]

Thank you. What is that? It looks cool

[thin aurora]

Sharplab

[potent sleet]

is there a reason you can't have QuestManager as Monobehavior ?

[gray thunder]

You're trying to access something you haven't assigned in the inspector

[pseudo zodiac]

Yes, it's because I cant make a list of Quest in my QuestManager. I need to instanciate them.

[gray thunder]

They can still be MonoBehavior?

[pseudo zodiac]

No they can't otherwise I cant make a list of all my Quest in my QuestManager.

[heady iris]

I don't understand.

[rain minnow]

huh? how is this not possible?

[odd pecan]

Is it possible to edit this in game ? or through script

[heady iris]

sure

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

AddKey, MoveKey, RemoveKey, SmoothTangents

[odd pecan]

oh thanks.

[lethal plank]

oh ok thanks

but i cant find any xd

[pseudo zodiac]

It's how it works, Unity wont let me create a list of class objects inheriting from monobehaviour at runtime

[rose token]

I'm trying to make a pickup script in unity. When I walk over a weapon I want it to be placed in the players hand. My current attempted solution was to parent the weapon to the lowerarm of the player. But the scale and rotation is all wrong when I do this. Also I seem unable to rotate my weapon to the right angle

This is my code

public void OnTriggerEnter2D(Collider2D col)
    {
        // Pickup gun
        if (col.gameObject.CompareTag("Player"))
        {
            Shooting shooting = col.gameObject.GetComponentInParent<Shooting>();
            if (shooting.holdingWeapon) return;
            

            this.transform.position = shooting.LowerArm.transform.position;
            this.transform.parent = shooting.LowerArm.transform;
}

result

[heady iris]

does your player have any non-uniform scaling?

i.e. scaling that isn't 2,2,2 or 0.5,0.5,0.5 or whatever

[static matrix]

RuntimeNavMeshBuilder: Source mesh Cylinder.001 does not allow read access. This will work in playmode in the editor but not in player

How can I fix this? I genuinely have no idea

[heady iris]

ah yeah, I ran into this recently

and it did, indeed, not work in the player!

so you're trying to generate a nav mesh at runtime

[static matrix]

yeah, because I have a procedurally generated level

[rose token]

yes, my lower arms scale properties are the following

[heady iris]

if you tell it to use render meshes, not colliders, the meshes will need to be marked read-write

I'm not sure if you can mark the built-in meshes as read-write..

[static matrix]

its not builtin

[heady iris]

o right

[static matrix]

where would I mark that?

[heady iris]

Cylinder.001

that's totally from Blender

anyway, go to the mesh asset

[static matrix]

yeah lol

k

go on

[heady iris]

you'll want to tick Read/Write

[static matrix]

I dont see that

[heady iris]

This will keep an extra copy of the mesh data in main memory, iirc

Show me the inspector.

[static matrix]

nothing to click here

[heady iris]

ah, I mean the asset itself

not the assets it contains

[static matrix]

ahhh

ok

[heady iris]

i think i need better names for those two concepts

[static matrix]

let me try and find that

ahaaaa

ok

thank you

[heady iris]

np

[static matrix]

lets see if not break

ok yeah, just need to do that for all imported models

then the thing should work

next step is solving the freezeframes whenever a new chunk is genned and generates the navmesh

[heady iris]

you can select many assets and check the box all at once

[static matrix]

yeah, I only have 2 rn so it isnt that bad

[static matrix]

I might try coroutines for this

[heady iris]

i don't know too much about runtime navmesh generation yet

[static matrix]

well I'm boiling it down to "Laggy thing happens and suspends running"

so if I try coroutines maybe it wont suspend

[heady iris]

if the function that builds a navmesh returns after the navmesh is built, coroutines will not help

you can still hang the game from a coroutine

coroutines are not magic; they're just capable of yielding to suspend execution

[static matrix]

ok mayb async then

[heady iris]

ah yes

https://docs.unity3d.com/Packages/com.unity.ai.navigation@1.1/api/Unity.AI.Navigation.NavMeshSurface.html

UpdateNavMesh(NavMeshData)

AsyncOperation is just a coroutine that peeks at an async operation to see if it's done

[static matrix]

time to learn ✨ Threading ✨

[rose token]

Can I get some help please?

[static matrix]

hmmm

idk

[rose token]

Been waiting for 10 minutes now

[static matrix]

not sure

[fiery shell]

if you parent something to another transform, that child will then use the parent scale as their reference, which means a non uniform scaled parent will cause weird scaling and rotation in their child. Usually, if it is absolutely essential to scale a rendered object via the transform, people tend to parent it put the renderer as a child to the uniformly scaled transform that is then used for logic animation etc.

So the first step to solve your warped gun issue is to make sure the transform you are trying to parent it to is uniformly scaled (as in all three numbers in the scaling vector have the same value)

[static matrix]

zyesss it worked

perfectly

the first time

[thick bough]

You can't parent it directly under the hierarchy when you have it scaled like you do. you have other options like using a script to copy position and rotation from another transform in Update

Alternatively reorder your hierarchy like Christopher is saying

[heady iris]

non-uniform scaling is, in general, The Devil

it's okay for "leaves" -- transforms that have no children

[buoyant crane]

@rose token in addition to this, there’s this component https://docs.unity3d.com/Manual/class-ParentConstraint.html

[thick bough]

Ah sure, nice!

[rose token]

Could I get an example of how to use the ParentConstraint

[rain minnow]

It's free help from others on their own time, doesn't matter how long you're waiting. People will respond if and when they know how, be patient . . .

[west lotus]

Everything you need is in the documentation

[heady iris]

i remember it being a little confusing to set up a constraint via script

here's how I configure a LookAtConstraint

void Awake()
    {
        target = GetComponentInParent<Entity>();
        health.target = target;
        lookAt.AddSource(new() {
            sourceTransform = Camera.main.transform,
            weight = 1f
        });
        
        lookAt.constraintActive = true;
    }

[rose token]

That works like a charm with the ParentConstraint

Thanks a lot guys

[heady iris]

i use ParentConstraint to get around how VRChat scales your head down really tiny

it's handy

[rustic ember]

Why can't I have two variables with the same name in different cases in a switch statement?

[heady iris]

oh lord, switch statements...

the tl;dr is that a switch statement is one big block

notice how it's all wrapped in a single pair of curly braces

However, there's nothing stopping you from doing this:

        switch(Time.frameCount) {
            case 1: {
                int x = 3;
                break;
            }
            case 3: {
                int x = 5;
                break;
            }
        }

in fact, you can slap down block statements wherever you want!

{ { { { { { { { { {
  print("hi :)");
} } } } } } } } } }

You usually use them after if because if only affects the next statement

A block statement is a single statement that contains several statements

thus letting you execute all of the statements in the block if the conditional is true

this is why they're optional for one-liners

if (foo)
  bar();

if (foo) {
  bar();
}

both of these have one statement after the if statement

[strong cloud]

I wonder what the performance impacts are of one versus the other, if any

[heady iris]

all of this gets chewed up by the compiler

it just needs to know, logically, what stuff should be skipped if the conditional fails

the IL (intermediate language) has no notion of "statements"

[lone zealot]

hey everyone. so I was wondering if I can have a child class not having to write a redundant line of constructor...
i.e. parent is

class P {
  public P(int a){}
}
``` and child is
```csharp
class C:P {
  public C(int a) : base(a){}
}```
is there a way to escape this insanity?

why can't the compiler just realize that when I don't write anything for the child, i want it to use the parent's constructor?

fyi this gives error

class C:P {}```

[heady iris]

them's the rules

[lone zealot]

it's very, very inconvinient for large objects...

three lines of redundant code.

[heady iris]

yeah...

look, at least we're not writing Java :p

[lone zealot]

yeah youre right. should be greatful

[heady iris]

i used to love Java, back in college

🫠

C# is just Cooler Java, when you think about it

[lone zealot]

if we factor this out, that is (the blue lines are redundant but forced)

we could use required and initializers in modern C# versions. but not in Unity's old C#

[lone zealot]

me too. What I loved about Java was... umm, there wasn't any reason other than I only knew Java back then

[heady iris]

I like ummm the uhhhhhhh

the uhhhhhhhhhhhhh

well it was a managed runtime

java was like sweatpants

i say, as i sit in my bedroom, wearing sweatpants

(i'm sick ok)

[lone zealot]

it's just the Java syndrome kicking in. you'll be alright after a few more lines of C#

[heady iris]

crux@Fens-MacBook-Pro Scripts % find . -name "*.cs" | xargs wc -l | tail -n1

Something really weird is happening. I add 7 elements to a list in the editor but when I debug the list it's got 0 elements in it

[heady iris]

is it getting reassigned somewhere?

e.g. set to new() in Awake or Start

[river wigeon]

I don't think so

I'll post

it's a private field too

[heady iris]

hmm, I wonder if it has something to do with multiplayer

[river wigeon]

how so?

[heady iris]

[hands waving around]

[dusk apex]

Show your console tab.

[heady iris]

but I wouldn't expect that, hmm

[river wigeon]

this class works everywhere else fine

and if I set this state to be the first state in the state machine it works fine

that's the console

so there are definitely 0 elements in the list

[dusk apex]

When do you call onEntry?

[river wigeon]

that's the state in the editor, with 7 transitions in the list

[river wigeon]

when the state is entered

[dusk apex]

The code shown won't help us. It'll only tell you/us where you've printed the value.

[river wigeon]

What code should I show?

[dusk apex]

Does the class have further code and any that changes the List?

Anything related to the List.

[river wigeon]

I'll send the full class, but it shouldn't change the list

[dusk apex]

Else it's an empty list if you've not added-to/modified the List

Which is important to be considered

[river wigeon]

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

[river wigeon]

I've added elements in the editor, no?

[dusk apex]

Maybe this is referring to a different object and not the one you've posted above.

Try printed the name of the object.

[river wigeon]

omfg

you're right

[dusk apex]

Debug.Log($"The object in question is {name}", gameObject);```

[river wigeon]

I accidently have 2 playPolicyState

and had the state transition going to the second one

omgg

thanks

I'm dumb

[dusk apex]

Well, you'll be able to move on now

[river wigeon]

yes, thank you. This has been a headache

it's always the little things huh

[heady iris]

aha, that'll do it :p

passing the object to the second arg of Debug.Log is super useful

How?

[heady iris]

What is the error

We can't tell you anything without seeing the error.

[heady iris]

and give us a paste with the code in it

I know that you can get some weird line numbers when dealing with coroutines

It has to generate a whole class to store the state of the coroutine

I just gave up lol

Not this time though

It happens before line 24

            manager.tiles[gridPositions[i].x, gridPositions[i].y].controller.EnableTileSelect(moveTypes[i]);
        }
        #endregion

        Debug.Log("Reached while true");``` It's in here somewhere

[mellow sigil]

either moveTypes is smaller than gridPositions or manager.tiles doesn't contains some of the positions

[rustic ember]

You are right

I fixed it. Thank you 🙏

[vast wyvern]

Good morning everyone 🙂

Wanted to inquire- has there been any changes or open issues regarding saving w/ persistantDataPath coming from Unity 2020 lts to 2021 lts? The plugin I am using stores assets onto the persistantDataPath, ex: AppData/LocalLow/CompanyName. In the new engine, some files can be written correctly to disk while others- such as a texture, model, and photo files- no longer write correctly. Previously on the older engine, all files would write to disk successfully from an API call and download. On the new engine, this process does not start, presumably because it is getting stuck? No errors are caught nor does it exit the program, it just loops forever. The API returns 201 so its making a connection, just not initiating the download process.

Nothing has changed between these projects besides their engine version. I am searching through the code to see if there is a particular place it could be getting stuck but I am not sure where to break - I have been going through the code line by line with the debugger and have not hit where its getting stuck. If anyone is familiar, I am using AvatarSDK Cloud UMA Plugin 2.4. Overall, I am mostly trying to see if there are possibly external changes to the engine that could have disrupted this process to reconcile with the code. If anyone has any advice on how to debug this, its all welcomed. I have researched this to the best of my ability and did not see any open issues or changes that could match these symptoms.

[tepid river]

Hi all, I've got a question regarding UnityEvents. Is there a way to pass in both a dynamic parameter and a static parameter that's been set in the inspector? I haven't been able to get that to work directly, and I've toyed around with setting up a custom struct to allow me to but I can't come up with anything solid so far. Does anyone have any ideas?

[jaunty sleet]

Could someone check my code here? I have an array I am trying to use that I have set to size 5 but it says index 0 is out of bounds??? I don't know what's going on in it. The array is declared on line 39, and I try to use it on line 300. https://codeshare.io/QnN03R

[heady iris]

you mean you use it on line 302?

[uneven dagger]

So im trying to make an andriod game and wanted to test out the InputSystem. What im trying to do is when the player touches the screen a joystick appears on their finger and if they move their finger the joystick will also move. Ive deleted my code multiple times because I couldnt get the joystick to move when the player moved their finger. Any advice or documentation anyone can link me too would be extremely helpful.

[leaden ice]

You can only pass one parameter through the inspector

[leaden ice]

A very simple workaround is this:

public int param1;
public bool param2;

public void DoButtonThing() {
  SomeOtherFunction(param1, param2);
}```

you can thus pass any number of parameters you want

Yeah 302, the if statement starts on 300. Can you see any reason index 0 would be out of bounds? I am so confused with this lol

[heady iris]

the array is non-serialized, right

yeah, it's private

if it was, then it could have some other random size

[jaunty sleet]

Yeah, it a private array I am using internally

U can see I declare it as string[] behaviorParameters = new string[5];

So how is it possible for index 0 to be out of bounds?

[heady iris]

behaviorParameters[1] = "1"; is line 302

that's index 1, not 0

can you show your error

[jaunty sleet]

Yeah, it's the same with index 1

1 sec

@leaden ice Could u look at this if u have time? I have no clue why I am having this issue with basic stuff like array size lol #archived-code-general message

[rain minnow]

i wouldn't ping specific people into your questions . . .

[ocean river]

hey. i need help, i cant find the "project settings" documented everywhere.
i only have these sorta settings

dammit messed up the screenshot

[leaden ice]

why are you using Unity 5.6?

[ocean river]

im using a version that supports new 3ds.

[leaden ice]

so what's the issue exactly

what are you expecting to see and what are you seeing instead

[ocean river]

i cant find these playmode editor things

[leaden ice]

it's all under the Player settings

[ocean river]

oh thanks

[leaden ice]

it's the same menu

just presented differently

[ocean river]

you sure i cen edit the playmode configurations or something there

i want that reload scenes option

[leaden ice]

what reload scenes option

[ocean river]

dis

[leaden ice]

That's clearly under the "Editor" section

[ocean river]

sure.

[leaden ice]

That being said it either:

• Might not exist at all
• Might be in a different place

since you're looking at a much older version of Unity

[ocean river]

then i would have another question...
can i detect scene change in a persistent object?

[leaden ice]

wdym by "persistent object"

[ocean river]

ah

its created in every scene, if it does alr exist, destroy recreated copy

its always there and doesnt get destroyed

[flat willow]

So i declared an action:

 public event Action OnJump;

and whenever i try to call the action (with OnJump()) it results in a NullReferenceException, how could I fix this?

[leaden ice]

OnJump?.Invoke();```

is the typical approach

You will typically get an NRE if you haven't assigned any subscribers to the delegate and you try to invoke it

note this is basically short for:

if (OnJump != null) OnJump();```

[flat willow]

Oh alright

[heady iris]

yep!

[somber ether]

This may be an odd question. How do I save multiple ints or some other save method to playerprefs that can be split up. I am making a shop, but need to toggle each button to unlocked or not, I dont want to have a spam of prefs since the shop sells like 50 things. This is local saved to reduce database calls

[heady iris]

There's nothing wrong with having many entries in PlayerPrefs

especially just 50 things

[somber ether]

That means my unity inspector will have 50 int variables, and 50 if else statements...

[heady iris]

well, you probably want to abstract that a bit...

you'll have a list of 50 item definitions somewhere

[somber ether]

I was hoping for some method like saving 10000100101 and then grab the 0 or 1

similar to an array

[heady iris]

you could pack it all into a bit field, sure

that's perfectly doable

[soft shard]

If you only need this data to persist for the run of the game (as in, closing the game will lose the data), you could store it in a static or serialized class instead, if it does need to save after closing/opening the game again, id suggest maybe using JSON, or possibly a scriptable object (although you cant make changes directly to SO's in builds)

[somber ether]

code tho?

[somber ether]

its a shop with unlockables, it would lose their progress if it deletes when the game closes

[cobalt elm]

So after a couple changes I made (pretty much unrelated to this). This method is being called twice really fast for no reason. I am only pressing the button once? it was working a minute ago. Any help is appreciated thank you!

         
        pauseAction = input.actions.FindActionMap("Player", true).FindAction("Pause", true);
        pauseAction.performed += context => CheckPause();
        
        ////////

        public void CheckPause()
        {
            if (!GameManager.Instance.matchPaused)
            {
                GameManager.Instance.PauseMatch();
                MenuManager.Instance.Load("Pause");
            }

            else
            {
                GameManager.Instance.ResumeMatch();
                MenuManager.Instance.UnloadAll();
            }
        }

[soft shard]

If you want to keep the progress, then you could save it with a JSON file, the data would have to exist somewhere for it to remain persistant, PlayerPrefs could work its just limiting, and for a shop, it sounds like it could be a growing headache parsing a string or something similar to get each shop item

[somber ether]

using json will still have the same problem of 50+ if else statements

[heady iris]

again, no, it will not

imagine you have a setup like this

[somber ether]

Code example?

[heady iris]

public class ItemDefinition {
  public string identifier;
  public float cost;
}

List<ItemDefinition> items;

you would save whether or not you have unlocked each of the items, using the identifier as the key

maybe you'd keep it in a Dictionary<string, bool> in-game or something

to save it, you'd iterate over that dictionary, and, for each key, write the corresponding bool into a playerpref (using 1 for true and 0 for false)

to load it, you'd go through all the item definitions and try to get an int based on its identifier

foreach (var key in itemStatus.Keys) {
  PlayerPrefs.SetInt("Unlocked-" + key, itemStatus[key] ? 1 : 0);
}

something like that for saving

[somber ether]

Checked a video and it requires creating a new public function for each 50 items

[heady iris]

what?

[somber ether]

for toggling the object on and off or something

[simple egret]

Not if you use a collection like the Dictionary here

[leaden ice]

Use a collection such as an array or a list

[heady iris]

you write the logic once

then you just apply it for every item

this is fundamental to...game programming in general, really!

[somber ether]

thats what I mean, you want me to create a function for each item

[heady iris]

no, I do not.

What did I say that made you believe that? maybe there is something unclear.

[somber ether]

apply it for every item

[simple egret]

As long as you manage to bind one item of the collection, to one item of your UI for example, it can be done all at once. Like with the foreach loop

[somber ether]

You are giving me a lot of terms, but not an example, I have to google each of these

[heady iris]

you have a list of items

[leaden ice]

one function, with a parameter specifying which object to modify, or using a loop and modifying all of them

[heady iris]

you do the same thing for every thing in the list

[somber ether]

you mentioned bit fields, so im watching a video on that but it doesnt seem to be the right thing

[somber ether]

yes that would be nice

[heady iris]

I mentioned it because that's what you were describing.

I do not think it is a good choice.

[simple egret]

Sample, assign a new value to a list item

void EnableItem(int index)
{
  list[index] = true;
}

[somber ether]

and it saves the list to local data how?

id prefer prefs

[molten crane]

Do you know where I can file request for In app purchases plugin to have assembly definition?

[simple egret]

By looping over it, and storing each value. Refer to <#archived-code-general message>

It's not really the use of PlayerPrefs though, as its name suggests it stores preferences, like resolution, graphics quality, etc. You're better off saving that to a file.

Reading is one line of code, same for writing

[somber ether]

its mobile

[simple egret]

No problem. That also has filesystem access

[somber ether]

they usually have permission issues

[cobalt elm]

nvm, im writing a bunch of spaghetti code and i just deleted some stuff 👍

[simple egret]

Each app has its dedicated storage location created, when it's installed

Under Application.persistentDataPath

[somber ether]

Maybe I can save a list to binary file

[simple egret]

Or JSON, whatever works for you. No BinaryFormatter though, it has security vulnerabilities and is unsafe to use on unverified serialized data

[somber ether]

json has too many lines, its odd

[versed marsh]

this is quite possibly the worst code i have ever written that actually functions

[heady iris]

what

i am genuinely confused by this statement

[simple egret]

Not if you don't tell it to display expanded. Most serializers will strip out the whitespace to achieve the smallest size possible.

[leaden ice]

just use .root you animal

[somber ether]

json uses too many brackets

[heady iris]

wait, .root exists??

[leaden ice]

https://docs.unity3d.com/ScriptReference/Transform-root.html

[heady iris]

the more you know

nice

[simple egret]

Yeah it's nice to check if you have a parent or not, transform == transform.root

[versed marsh]

then id have to do like root.child.child or something cuz it's inside a canvas which is inside another gameobj 😭

[pliant sapphire]

Hi everyone! I have my player to have a Shield in front of him with box collider and different layer and tag from player. when player click RMB. But when it collides with an enemy it still takes away my health and I dont really know why cause it shouldnt do that based on my scripts. This is my Health script: https://hastebin.com/share/humemiyixu.csharp This is Script to take damage from a player when collision happens:https://hastebin.com/share/aforebepag.csharp This is player attack script where shield using is:https://hastebin.com/share/uyelerajez.csharp

[leaden ice]

or just assign it in the inspector like a normal person

[versed marsh]

wont work since the item its checking for is constantly being added and removed

[leaden ice]

assign the thing that holds the added/removed thing

and/or make a variable for it.

Code like this that relies on the hierarchy being arranged in a certain way is begging for difficult-to-debug bugs later on

when you inevitably rearrange the hierarchy

[heady iris]

yes

you will experience immense pain

[versed marsh]

yeah i will likely change it but for now i am too lazy and stubborn

[heady iris]

I prefer to just do GetComponentInParent as long as I know that the thing will always be a child

[versed marsh]

thats a problem for future me

[heady iris]

the UI system in one of my games has lots of components that all look for the UI manager by getting a parent component

[pliant sapphire]

can someone pls try to help me with this

[wild hamlet]

Hi I'm working on a Multiplayer project with Netcode for GameObjects. I'm trying to make a rigidbody object but it moves laggy and unnatural in clients.

I added Network Object, Collider, Rigidbody, NetworkRigidbody and Network Transform to my gameobject

[heady iris]

the built-in components for this are going to be laggy looking

they don't do some of the more advanced stuff that makes modern multiplayer games smooth (like client-side prediction)

for example, NetworkRigidbody is only simulated by the owner of the object

for everyone else, it's kinematic

[leaden ice]

https://docs-multiplayer.unity3d.com/netcode/current/learn/clientside_interpolation/index.html

https://docs-multiplayer.unity3d.com/netcode/current/components/networktransform#interpolation

[wild hamlet]

interpolation in networktransform makes it too unnatural but when i disable it stops in air and teleports to next position

[polar marten]

there is unfortunately no generic solution that looks good for everyone in all situations

what is the game?

[wild hamlet]

It's just and picking up and dropping items

[polar marten]

and does this have to be over the internet or just the LAN?

for the sake of prototyping

[polar marten]

what is the game though?

[wild hamlet]

It's a coop fps game

[wild hamlet]

over the internet I'm going to use steam matchmaking

[polar marten]

do you have a screenshot

and how far along are you?

[wild hamlet]

I just started last weak not much

[polar marten]

okay well i guess you can fiddle with the interpolation settings

is that the only thing you want to know about?

yesterday someone asked about making a networked fps and it was really difficult to talk about so i am pretty spent on this issue. it is way harder to make internet networked FPS experiences in unity than it appears.

[wild hamlet]

yeah I don't have problems with other things for now

I was going well but then i noticed object was lagging/jittering

[leaden bluff]

if anyone has a moment i need help with smth

https://answers.unity.com/questions/1944975/issues-with-2d-knockback.html this

[polar marten]

based on this message, i don't think you're ready to do this either i'm sorry

[polar marten]

you are mutating your knockback force so this isn't surprising

you have a knockbackForce *= damping line

[polar marten]

you might get better help in #💻┃code-beginner

[leaden bluff]

sorry im not the best with understanding c# yet, how should i fix this?

[wild hamlet]

as i said i just started last week this was the first problem that i came up with

[polar marten]

it is way harder to make internet networked FPS experiences in unity than it appears.

like here is what you think the difficulty is:
1
and here is what the difficulty actually is:
1111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111

[polar marten]

take a look at that line and debug it 🙂

you can print it too

and see how knockback changes

[wild hamlet]

it may be but I'm trying to learn why would i just drop off the game because it has difficulties

[leaden bluff]

alr thanks

[polar marten]

sorry i can't be more help

[leaden bluff]

still not sure how to fix this

i want the speed that the player is being knocked back at to gradually decrease each time it gets knocked back, but i dont want seperate knockbacks to differ from each other if that makes sense

[cerulean oak]

is there any way to cheat the number that DateTime.Now returns, for debugging purposes?

other than changing the pc time

wich is I guess what i'll end up doing

[somber ether]

Whats the code to read json or loop through entries? I used entries.Add(new InputEntry(producttype.ToString(), 1)); on each item purchased, now what I need is all of them who have 1 or data entry at all will have a gameobject enabled

I assume I will have to add every button to a serialize field

Thats the file managing class (got it from tutorial) but they didnt show usage of it

[pseudo zodiac]

does anyone know why my Couroutine stop at the yield return and doesnt execute the StartCoroutine at the end ?

IEnumerator OnCompleteAttack(bool succeeded)
        {
                success = succeeded;
                if (success)
                {
                    Interface.SetDialogText("Attack succeeded !");
                    
                    DecreaseEnemyAppreciationBy(10);
                    yield return new WaitForSeconds(1);
                    Debug.Log("marche ta mere1");
                }
                else
                {
                    Interface.SetDialogText("Attack failed !");
                    Debug.Log("marche ta mere2");
                    yield return new WaitForSeconds(1);
                }
                Debug.Log("marche ta mere3");
                StartCoroutine(EnemyTurn());
                
                yield return null;
        }

[latent latch]

Put some debugs after you start the coroutine and inside of EnemyTurn

[pliant sapphire]

Does anyone know why my knockback doesnt work on my enemy, this is enemy take hit script: https://hastebin.com/share/pitabodosu.csharp

[pseudo zodiac]

So I put a Log at the beginning, it works. This is weird, it seems like yield return stop my Couroutine

[latent latch]

Instead of yield return null, try yield return StartCoroutine(EnemyTurn());

I expect it be a scoping issue, but I still think the coroutine would live on the mono somewhere. I forget exactly

[pseudo zodiac]

It doesnt work.

My IEnumerator is a local function is that a problem?

Like here is the full function

private IEnumerator PlayerAttack()
    {
        bool success = false;
        
        attackMenu.OpenMenu(Player, OnSelectAttack);

        void OnSelectAttack(AttackObject a)
        {
            if (a == null)
            {
                return;
            }
            Debug.Log("Selected attack");
            StartCoroutine(performAttack.StartAttack(a.input.sequence.ToList(), 15, OnCompleteAttack));
        }
        
        IEnumerator OnCompleteAttack(bool succeeded)
        {
            Debug.Log("123");
            success = succeeded;
            if (success)
            {
                Interface.SetDialogText("Attack succeeded !");
                
                DecreaseEnemyAppreciationBy(10);
                yield return new WaitForSeconds(1);
                Debug.Log("marche ta mere1");
            }
            else
            {
                Interface.SetDialogText("Attack failed !");
                Debug.Log("marche ta mere2");
                yield return new WaitForSeconds(1);
            }
            Debug.Log("marche ta mere3");
            
            yield return StartCoroutine(EnemyTurn());
        }

        yield return null;
    }

[latent latch]

remove the return null

[pseudo zodiac]

It makes an error if I return nothing

[latent latch]

oh yeah you got it nested uh

[pseudo zodiac]

yeah

is that a problem?

[latent latch]

I feel like it should be fine, but I'm rusty at them. I'd probably need to fool around with it for a bit to refresh myself.

Because even if the first coroutine returns, your other (inner) coroutine should still be running

[pseudo zodiac]

I dont know what to do

[leaden ice]

There's no reason for this outer function to be a coroutine at all

And typically if your coroutine is not resuming from a yield it's because the GameObject it's running on was destroyed or deactivated

[swift falcon]

I did something horribly wrong in my code didnt I

I dont even understand

[heady iris]

What are you trying to download?

[swift falcon]

My own game / app

lmfao

[heady iris]

virus detection is...messy

[swift falcon]

Yeah

[heady iris]

it's very likely that you just randomly wound up with something that looks vaguely like a bad thing

[swift falcon]

Does it scan what the application does? or something like that

[heady iris]

it's a real rat's nest of different techniques and signatures

one thing that comes to mind is flagging things that appear to be, say, starting other processes, or downloading files

oh hey (:

perhaps that's what is making it mad

[swift falcon]

Oh yeah, I didnt include that but I did include a File.Create

But that usually doesnt do anything for the virus detection, ive done it before

[leaden bluff]

can anyone help with this? sorry if im being annoying about it lmao

its just been on my to-do list for a while but i have no idea how to fix it

[swift falcon]

Okay buddy

Thats def not in my app 💀 @heady iris

[heady iris]

they're probably both seeing the same (wrong) signature

[swift falcon]

Damn

ill search about this thing

[ocean river]

this may be a basic question, but i want the spotlight to be NOT smooth
just a little, but it should clearly be a circle.

[heady iris]

i forget the name of the field you want

angle something

[ocean river]

i changed angle and stuff but it doesnt affect it...

[heady iris]

Inner Angle (%), at least in the HDRP

[ocean river]

using unity 5.6.5

[heady iris]

ah

[swift falcon]

@heady iris I found out the Issue
Windows really doesnt like "GetAsyncKeyState(Int32 i)"

I put it in there for testing and experiments, it seems to think the program is a virus if that function is used

Quite annoying

[heady iris]

Interesting.

Oh

It's probably a keylogger thing.

[leaden ice]

Probably because that function would be something a keylogger/screen recorder virus might use

[swift falcon]

Yeah I think so

Still sad if youre trying to use it for something not malicious

[pseudo zodiac]

Thanks

[uncut path]

Why am i getting an error, the audio is in it

[heady iris]

Something on line 44 is null.

Log the variables and find out.

[uncut path]

ill try that

[mossy snow]

likely func, AudioUtil doesn't seem to have a method called GetClipPosition in my version (2021.3.19f1)

[heady iris]

it doesn't actually matter if the clip is null

that won't cause an error on that line

the only thing that could be null (and problematic) is func

[uncut path]

I have a feeling its new System.Object

[heady iris]

i have a feeling it's not

log func

[uncut path]

k logging

it says null

i wonder why

[heady iris]

there ain't a function with that name.

there's a thing called GetPreviewClipPosition ...

[uncut path]

I tried

var func = type.GetMethod("GetPreviewClipPosition", new [] { typeof(AudioClip) });

[heady iris]

i'm going off of https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/Audio/Bindings/AudioUtil.bindings.cs

[uncut path]

Thanks for your help, sorry I'm kind of dumb

[fallen lotus]

this code is causing an error:

Invoke(JoinLobbyByCode(joinCode), 2f);

The error is Argument type 'void' is not assignable to parameter type 'string' and its under the method

anyone know why? can invokes not pass a value in as a parameter? the function im trying to call is also an async. could that be the issue?

[heady iris]

this is not how you use Invoke

Invoke takes the name of a function

[fallen lotus]

OHHH

[heady iris]

you are calling JoinLobbyByCode(joinCode) and then trying to give its return value to Invoke :p

[fallen lotus]

omg i forgot

so it cant pass parameters

ive made this exact mistake before i just forgot lmao

[heady iris]

use a coroutine, yeah

[slender basin]

Assets\Movement.cs(5,38): error CS1003: Syntax error, ',' expected

ik this belongs in beginner but no one was responding please help

[heady iris]

the syntax for a class declaration is

public class ClassName : ParentClass {
  // ...
}

compare this to your code.

[slender basin]

so

i changed to semi colon to the end brakced

public Rigidbody RB3D;
is in they way

[heady iris]

you should not "change" the semicolon to anything

remove it

[warm wren]

Dude just configure your !ide. It will make your coding life so much easier

[tawny elk]

💡 IDE Configuration

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

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

• VS Code*
• JetBrains Rider
• Other/None

*VS Code's debugger plugin is unsupported.
We recommend using VS or Rider instead.

[heady iris]

yes, you still need to do this

[slender basin]

i tried

my unity hub isnt the same

[simple egret]

The config is done from an open Unity project, and the Visual Studio Installer program, as VS is already installed

Skip the steps you already completed, like the part where they use the Hub to install VS

Configuring your IDE is required to get help here

[heady iris]

everything from this point on is in the unity editor

[slender basin]

i dont get it.

[heady iris]

What do you not get?

[slender basin]

i cant find

[slender basin]

this

[heady iris]

Can't find what?

The preferences menu?

[slender basin]

yes'

i have one

but it isnt the same

[heady iris]

are you still looking at the unity hub?

if not, are you looking at the Project Settings?

[slender basin]

not currently

[heady iris]

follow the instructions. Edit > Preferences

[slender basin]

im in my project

[heady iris]

not Edit > anything else

it's not "not working"; you have a compile error

what is the error?

ah, yes

it's because the method is a static method of GameObject

or Component

so, if your class derives from Component, you can just say FindObjectOfType directly

because it's implicitly like saying MonoBehaviour.FindObjectOfType

you just need to prepend GameObject. to that

[slender basin]

Common7/IDE

[heady iris]

np

[slender basin]

i just like wut

[heady iris]

what?

where is this from?

[slender basin]

i need to get to Common7/IDE

its

in the instruction

[heady iris]

no, you need to select a version of Visual Studio that you have installed

if your version of Visual Studio is not listed, you did not follow the instructions.

[slender basin]

i have one installed version from 2019

[weary depot]

peeps

[heady iris]

Did you just install it?

[slender basin]

no ive had it since i started

[heady iris]

Does it show up in that dropdown list?

[weary depot]

I have to deliver an essay in like a day and have one simple question, up until incremental GC did unity use generational GC?

[slender basin]

this and browse is all i have

[heady iris]

that looks fine, then

[slender basin]

what

[heady iris]

Yes, I think you should uninstall your copy of Visual Studio and install VS 2022

then follow the rest of the instructions

[heady iris]

.NET uses generational GC, so I would expect so, yes

although, a generational GC is incremental

https://stackoverflow.com/questions/5092134/whats-the-difference-between-generational-and-incremental-garbage-collection

[weary depot]

I had the same impression but I read some articles stating something about mono NOT having generational GC hence so did unity in turn. But this helped, thanks!

[fathom patrol]

how do I change a [SerializedField]'s value from in another file

its too late and my brain is dying

[heady iris]

That’s possible, yeah. I am not familiar with the internals of Mono

[fathom patrol]

[SerializeField] Vector2 maxPos;
    [SerializeField] Vector2 minPos;
    
    public Vector2 MaxPos 
    {
        get
        {
            return maxPos;
        }
        set
        {
            return;
        }
    }

    public Vector2 MinPos
    {
        get
        {
            return minPos;
        }
        set
        {
            return;
        }
    }

code rn

[heady iris]

Being serialized is irrelevant

It’s private.

(Since fields are private by default)

[fathom patrol]

but I public it in my code right

[heady iris]

You have properties.

Their set methods do nothing.

Both of them just instantly return.

[fathom patrol]

i should probably head to bed 😭

[heady iris]

you need to assign the value to something

(in a setter, the value you’re trying to store is called value)

[slender basin]

i dont get it i know i sound dumb bvut my unity hub install portion literally doesnthave an add button the onlyh option or upodate or any thing on my visual C is 2019

[fathom patrol]

would this work then

get
{
    return minPos;
}
set
{
    Vector2 maxPos = value;
}

[heady iris]

No, that is declaring a brand new variable.

Just set maxPos

[fathom patrol]

    public Vector2 MaxPos 
    {
        get { return maxPos; } set { maxPos = value; }
    }

    public Vector2 MinPos
    {
        get { return minPos; } set { minPos = value; }
    }

okay ill just head to bed and do this tomorrow since my brain cant even work out this simple stuff anymore

[uncut path]

i need some help wrapping my head around this. shold i take this to beginner?

[heady iris]

That looks correct

[heady iris]

Eh, reflection and editor stuff aren’t beginner

[uncut path]

is there documentation on Director Timeline/Animation programing?

https://github.com/keijiro/AudioPreviewTrack

this is the script that is giving me errors and im trying to fix it but it might be over my head and like @mossy snow mentioned AudioUtil might be depreciated

[uncut path]

if UnityEditor.AudioUtil was depreciated how do i look though the UnityEditor API, Library, or dll for an alternative?

I figured out how to poke at it.

[steel vortex]

Hey guys, have a problem, I put my player in a prefab folder because I have a dungeon generator and it spawns the player randomly and for that it has to be a prefab and the player needs in his script the camera but as a prefab I can't assign cameras, why? Or how do I fix this?

because This is a 2D roguelike game and he shoots in the direction where the mouse arrow is and for that he needs the camera.

okay

ah okay

https://sourceb.in/NTa26r3hJl my Player Script

[finite hollow]

Hey guys! I'm a little stuck with this thing I want to implement. I wanted a dynamic screen, wherein I push a button and the camera would pan to specific location. I was thinking of moving the camera with a lerp, where the startposition is where the camera is located and then the ending position is the targetposition, and I put it in a function that is then attached to the buttons onclick. ... Should I not have done that? Because it seems like every tutorial I've seen puts lerps in updates haha...

[steel vortex]

xD

[uncut path]

nope didn't do any poking just looked closer at AudioSource and AudioClip cant find audioutil

[steel vortex]

is that how it should be?

no I mean the punch animation

sorry i mean sword animation

ah okay, but looks nice

but even if I separate that, how do I do that with the camera?

nice

The lower camera should be assigned not the normal

Camera Movement works everything only the player does not turn to my mouse because it needs the camera

Followed some tutorial and then found this dungeon generator with the 2 cameras

both

good question

https://github.com/mihailt/LevelGeneration this is the generator which i use

https://www.youtube.com/watch?v=L_GPgTeTpZI&list=PLfX6C2dxVyLyBec8ibuPibcpTtoQRbo7n&index=8 and the tutorial

I did the tutorial and then found the generator and just copied it into my game

I have just tried to use one no matter which of the two, as soon as I remove one goes nothing more

[cosmic rain]

They're using Cinemachine. One is a virtual camera, the other one is an actual camera

That's how Cinemachine works.

It's a package for controlling the camera. You can google that.

[steel vortex]

In the "LevelGenerator" script I have to drag in the camera "CM vcam1" and in the cam is in there:

yea

And a tag then give the camera and assign that in the script and done?

google says that ```public Camera catchingCamera;

if (catchingCamera == null)
catchingCamera = GameObject.FindGameObjectWithTag("CatchingCamera").GetComponent<Camera>() as Camera;```

okay, i´ll try

[uncut path]

I'm trying to put AudioUtil back so i can use it but i cant find mono

i tried putting it in Assets but i got errors

"Put back"?🤔

[uncut path]

Where do i put this on my computer
https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/Audio/Bindings/AudioUtil.bindings.cs

[cosmic rain]

Why would you want to put it anywhere? It's just for reference. The actual code is in the unity dlls

[uncut path]

how do i look at what is in the dll?

[cosmic rain]

You don't... I mean, I guess you could try inspecting the correct dll in the ide, but what for..?

What the heck are you trying to do?

[uncut path]

im trying to use this to scrub through audio so i can do facial animation

var type = Type.GetType("UnityEditor.AudioUtil,UnityEditor");
var func = type.GetMethod("GetClipPosition", new [] { typeof(AudioClip) })

[leaden ice]

Don't you need binding flags for static methods?

[uncut path]

someone said AduioUtil is probably depreciated but i cant figure out how to take a closer look at AduioUtil or UnityEditor to find an alternative

[cosmic rain]

Try generating project files in unity - preferences - external tools with all the checkboxes above checked. Then you should be able to see the editor assembly in your ide. You can explore it to find the class you're looking for.

[mossy snow]

did you read the notice at that link? There's probably a reason it's 6 years since an update

"global variable?"

"static."

[mossy snow]

Your bug probably isn't in this snippet. Look inside InventoryObject and see what it has in Container. Setting a breakpoint on line 25 of InventoryReader and working thorugh what that loop is doing and why will show you whatever is causing this

[strange epoch]

I need help with a bug in my game. Whenever the scene is reset the values of some variables are set to 0 or null. for example, when the game is reset, the player's speed is set to 0 for some reason. This has never happened to me before. I'm using github, I don't know if that could have anything to do with it.

[cosmic rain]

Where is that variable that's resetting? On a scene GameObject component?

Did these variables have a different value prior to you pressing play?

[plucky karma]

Any chances you may have some static variables around?

[leaden ice]

GitHub is definitely 100% irrelevant 🤣

[olive shore]

bruh does anyone know why googles giving me this despite me already having the snippet: <uses-permission android:name="com.google.android.gms.permission.AD_ID"/> inside of my android manifest?

[undone remnant]

Hey guys

[potent sleet]

#📱┃mobile

[olive shore]

sorry, thanks

[potent sleet]

i mean if it works it works right ?

well you can firstly just probably do

        while (!loadingOperation.isDone)
        {
            yield return null;
        }```

 if (minLoadingTime > 0)
        {
            yield return new WaitForSeconds(minLoadingTime);
        }

        loadingOperation.allowSceneActivation = true;

the line yield return null after setting loadingOperation.allowSceneActivation = true is unnecessary

[cosmic rain]

I don't think there's a need for refactoring, but I think there's an issue with your waitTime and totalWaitTime.

[potent sleet]

at least you noticed it was kinda not needed tho
// should this even be here?? ??

Maybe what Null suggested though.

Is there a way to determine if a urp decal projector is rendering without constantly checking the distance the player is from the decal ‘bounds’?

[latent latch]

I would expect it to cull if the bounds are not* in camera view, or maybe I'm mistaken. Usually how it works with the vfx graph.

[lost dove]

Hi, I'm trying to use tweening (DotTween) to make my object move in a random direction on the screen, then come back and slam into a position quickly.
my code is as follows:

            if (targetPiece != null)
            {
                var captureDestination = pieceMoveDestination += new Vector2Int(UnityEngine.Random.Range(-1, 1) * 5, UnityEngine.Random.Range(-1, 1) * 5);
                var captureTween = DOTween.To(() => movingPiece.transform.position, x => movingPiece.transform.position = x, captureDestination, 1f);

                while (captureTween.IsActive())
                {
                    yield return null;
                }
            }

            // Standard movement
            var tweener = DOTween.To(() => movingPiece.transform.position, x => movingPiece.transform.position = x, pieceMoveDestination, 1f);

            while (tweener.IsActive())
            {
                yield return null;
            }```

my issue is that it goes out as expected, then teleports back to the original position and then slowly going to the final position.

Any ideas?

[latent latch]

There is a draw distance I know on the projector, but I'm not too sure if there's a sure way method to checking if it's being culled

[glossy basin]

Hello there, I would like to use the cellular noise from the unity mathematics package and preview it , however I dont know how to activate it; I want to preview this noise into a 2d texture but it uses a float2 instead of a float, so How do I render this ? standard noise is as easy as this

Nvm, it turns out it returns F1 and F2 from cellullar so you can use x or y value

[plucky karma]

Am I'm running into precision problems?

 private void OnDrawGizmos()
    {
        var pos = transform.position;
        var nearClip = _cam.nearClipPlane;
        var horzFrac= (Screen.width + 0f) / horizontalCount;
        var vertFrac = (Screen.height + 0f) / verticalCount;
        Vector3 screen;
        screen.z = nearClip;
        for (var x = 0; x <= horizontalCount; ++x)
        {
            for (var y = 0; y <= verticalCount; ++y)
            {
                screen.x = x * horzFrac;
                screen.y = y * vertFrac;
                pos = _cam.ScreenToWorldPoint(screen);
                Gizmos.DrawSphere(pos, size);
            }
        }
    }

revised for better naming convention.

[undone remnant]

hey can someone please help me with my code

[obtuse cedar]

i was told that I shouldn't rely on singleton too much
but I can't think of a better pattern to do this.

basically i want a pool of bullets

so i was thinking of making it signleton

so guns can quickly access that pool and recycle bullets

the only problem is if I want to access different types of bullets with different propperties i would have to make more pools
idk if this is a good approach

[plucky karma]

What you can do instead is create one Singleton to handle serving services.

E.g.

ServiceManager.Instance.Get<BulletPoolManager>();

You would then create a interface to justify which class can be treated as ServiceManager, only that it includes some sort of function to properly initialize/spawn if it doesn't exist initially.

Otherwise, consider looking into Dependency Injection.

[strange epoch]

The variables are on script on a game object. If I set the value of a variable and then hit play, it works fine, but when the scene is reloaded the variable’s value is set to 0

[cosmic rain]

And is it set to 0 before you hit play?

[strange epoch]

No

[latent latch]

Object pool is probably one of the better uses for a singleton

[cosmic rain]

What if you set it to some non 0 value, then close the project and open it again. Does it keep the value that you set?

[strange epoch]

It does, it only changes the value when the scene is reset during play

It doesn’t happen only with floats, if I assign a game object to a public variable, it is set to null when the scene is reset

[plucky karma]

Pretty sure Unity has implemented their own version of object pool in the recent version of Unity....

[strange epoch]

And if I stop the game the variables go back to normal

[latent latch]

I think I looked at that, and unless it does something under the hood that does anything fancy, it's very similar to that of a singleton design

[somber nacelle]

unity's object pool isn't a singleton at all. but you can use it in a singleton

[leaden ice]

What exactly does scene reset mean

[strange epoch]

Load the current scene

[leaden ice]

Ok and is this script on a DDOL object?

What is a DDOL?

DontDestroyOnLoad

[strange epoch]

I don’t think it is, but I’ve never used that I this is the first time I’m having any trouble with this

You're going to have to show more information

And code

[strange epoch]

Ok

Here is a screenshot before hitting play

Here's during play before resetting the scene, everything works fine here

I'd guess one or more of your other scripts are at fault

How's your slow time script work?
which script reloads the scene?

I'm not sure is a script, I just noticed now that a whole script disappears when the scene is reloaded

Here's is the script before hitting play

And here it is after reloading the scene

The WinState script disappeared

I think it might have something to do with the game object being a prefab

Its working, but its flickering between the sides of the point.

[urban marsh]

Hello everyone !
Is there a difference performance-wise between using fixedUpdate and Update in a script ?

[somber nacelle]

FixedUpdate does not run every frame. you should use it for physics related logic while using Update for most other stuff

[rain dove]

my probable guess u forgot to override changes to your prefab;

[strange epoch]

Yeah, that was it, but it still shouldn’t happen

And also when I assign a game object to a script it is set to null when the scene is loaded, is there a way to fix this?

Overriding the changes worked with variables like floats, but not game objects

[rain dove]

a prefab cannot hold another game object which is not part of the the prefab; u have to access that game object runtime;

u can assign it; but as soon as u will hit play it will loose its refrence;

@strange epoch

[strange epoch]

It works fine when I hit play, the problem only happens when I reset the scene

Would the same happen if the object wasn’t a prefab?

[urban marsh]

I understand that it "should" be like that, but : what is the reason ? 😄

[rain dove]

i dont think so; havent tried this; let me check this;

[somber nacelle]

because FixedUpdate runs in time with the physics engine updating

[urban marsh]

OK.

so it's more about doing "better movement" than "more optimized"

[latent latch]

It's useful to stick stuff like spherecasting and grabbing colliders in it since you don't want to be doing that every frame

[rain dove]

by reset scene u mean to reload the scece; or load scene from from one scene to another?

[strange epoch]

Reload scene

[rain dove]

okay it doesnt break; confirmed checking it; it keeps the refrence no matter what; im on 2019.4.20 lts

[fathom plaza]

Hi guys! Quick question, is it possible to have multiple instances of PointerEventData across different classes? Or would that produce conflicts?

[sage latch]

It's just a class so I don't see why not

[fathom plaza]

Oh okay. But for EventSystem, would there be conflicts should I plan on multiple instances of such across different classes?

[lone zealot]

hi, is it alright to use reflection when building with IL2CPP?

I could try, but if anyone has before, i'd be glad to let me know

[rain dove]

id rather suggest to create a common controller for handling pointerevent data; for optimization purpose; as if too many of those classes are active and loaded; would impact performance; nothing else is the issue; and if mulitple events are trying to modify the attributes of the same gameobject that can be a potential problem ;if u handle that with care no issues with having multiple pointerevent data

[lone zealot]

(finding a value by a dynamic string. so no AoT string magic)

[quartz folio]

as long as you're not using System.Reflection.Emit, it's fine.

if something isn't found via reflection it has been stripped, and you need to indicate to keep it

[fathom plaza]

yea this is what I thought of as well. Was just trying to confirm if what I observed is correct

Thanks for the help, everyone!

[lone zealot]

ah right makes sense. so anything else that's not stripped can be accessed via reflection? and I mean using a dynamic (unpredictable) string query

[quartz folio]

Yes. Everything works unless something was stripped because nothing referenced it explicitly

[lone zealot]

ah, thanks 🙏

[strange ferry]

Hello everyone, I was wondering if there's a way to add a dependency to a project to require a certain package, for example, I'm making a prefab that needs the 2D sprite package, do you guys know a way to tell the developer that it needs it to use the prefabs?

[wet pumice]

is System.Guid not serializable with JsonUtility?

[cold parrot]

It can only serialize what the unity serializer also can serialize (if it doesn’t show up in the inspector there is a good chance it can’t handle it)

[wet pumice]

Aye - have found a wrapper for it, good info though, thanks

[thin aurora]

Probably not. You're better off using a better serializer such as Newtonsoft or System.Text.Json, because JSONUtility is very bad at doing the thing it's made for. I believe Newtonsoft has a package for Unity. Alternatively you can put the DLL of it in a Plugins folder in your project to use it. System.Text.Json is much more work to get to work.

[strange ferry]

Guys do you know if you can do a coroutine to execute in edit mode?

[cosmic rain]

Yes. There's a package for editor coroutines.

[mellow seal]

Hey guys so i have a quick question

Should i define EnemyManager at start then use it on update

or use it in update like this?

EnemyManager.Instance.CanAttackPlayer();

[leaden ice]

It's not going to be a big deal either way

[heady iris]

There's basically zero difference as long as you aren't scanning the whole scene for the EnemyManager or something

[spiral ibex]

If it's a small game, it doesnt matter. If it's a big game, consider caching it during Awake which would allow for you to extend/change it more easily in the future.

[mellow seal]

oh okey thank you guys very much

[leaden ice]

Caching during awake is going to potentially introduce script execution order issues

[heady iris]

indeed.

[spiral ibex]

That doesn't seem likely...

[leaden ice]

It seems certain to me

Presumably Instance is assigned in Awake

[spiral ibex]

EnemyManager manager;
void Awake(){
  manager = EnemyManager.Instance;
}

We are thinking this right?

[leaden ice]

Yes and if that runs before the Awake that assigns it?

[heady iris]

It depends on how you implement EnemyManager.Instance, I guess

[spiral ibex]

I would assume that Instance is lazy initialized

[heady iris]

If it's assigned by the EnemyManager during its own Awake call, you're going to have ordering issues

If it's lazy-initialized, then it oughta be fine.

[leaden ice]

That's a dangerous assumption

And not very common

Relative to awake

[spiral ibex]

The other side of that coin is, imagine you have built a game where you have 50 psuedo singletons and want to migrate to a DI, now you have to fix hundreds, perhaps thousands of calls.

[leaden ice]

Such is the nature of refactoring code

[spiral ibex]

That's why I said If it's not a small game

[thin aurora]

You're not caching anything

The reference to EnemyManager.Instance already exists and you're "caching" the same reference

[thin aurora]

PraetorBlue is right. "Caching" the instance can be troublesome because Instance is most likely assigned in Awake of EnemyManager. This can cause a race condition.

[thin aurora]

So you're going to want to call it in update like that, or make a property to access it a bit easier:

private EnemyManager EnemyManager => EnemyManager.Instance;
void Update()
{
  this.EnemyManager.CanAttackPlayer();
}

I would argue that this is a good way to do this because you abstract the access to Instance. This might be nice for refactoring later if you decide not to make EnemyManager a singleton but instead get an instance of EnemyManager from a collection of dependencies, for example.

[heady iris]

properties are a nice way to abstract it, yes

[thin aurora]

Yup, and in this case it will only try to get EnemyManager.Instance when you call it.

If, for some reason, you do want to cache it, you can make the property store EnemyManager.Instance in a manually defined backing field, and retrieve it from there with later calls.

[coral kettle]

in unity2D. I want to make it so when you enter a specific area it changes the references to things to be things in that area. my first idea is a trigger box collider that covers the area and use OnTriggerEnter. is there a problem with everything always being in a trigger? can it screw with other triggers?

[gilded grove]

Is there any advantage on Invoking movement via InputAction like ctx.action.ReadValue<Vector2>() as a coroutine instead of reading the value on Update()?

[thin aurora]

Why not place boxes at certain entrances? I can imagine a massive square doesn't exactly cover the area that well.

Also, you need OnTriggerEnter2D, not OnTriggerEnter

[coral kettle]

hmm

[heady iris]

doing it in a coroutine feels weird

use a coroutine when you need to perform an action across several frames with state persisting from frame to frame

[whole steeple]

Wall-sliding for Unity 2D

[gilded grove]

Okay thank you

[leaden ice]

without any context whatsover on what you're doing, the advantage would be the normal advantages of using a coroutine

[heady iris]

more specifically, you should use a coroutine when:

• you're doing a one-off action
• the action needs to take place over several frames
• the action requires state to persist from frame to frame

the advantage is that you don't have to manually persist that state

you just let the coroutine hang on to it for you between yield statements

in case that's too abstract, by "state" I mean any data that's needed to do the Right Thing: a coroutine that shrinks an object over time needs to store the start and end sizes, and also remember how far along it is, for example

Movement doesn't really fit any of those criteria

you're always doing it (or, at least, you just toggle it on and off), and you're always doing the same thing every frame

[gilded grove]

The original question comes from whether or not it's cheaper to listen to an invocation (user pressed w to go forward) rather than calling update every frame.

[leaden ice]

It depends on the context

If you're getting an event pretty much every frame anyway

then it doesn't really make a difference

[gilded grove]

Thanks for the explanation, this seems what I'm curious about

[heady iris]

I prefer to just read values directly every frame

[leaden ice]

For something like movement I prefer polling

for pressing a button, events are good

[heady iris]

I found it awkward to do

OnMoveInput(InputAction.CallbackContext context) {
   lastMove = context.ReadValue<Vector2>();
}

[gilded grove]

I'll look into that as well, thank you

[leaden ice]

like joystick code especially

is super awkward as an event

[heady iris]

"polling" just means asking for the value yourself

[leaden ice]

much cleaner in Update

[heady iris]

versus "pushing" (?), where the input system tells YOU when something happens

(which is great for button inputs)

[gilded grove]

Great, this all adds clarity, thank you for the responses!

[heady iris]

np!

Pushing is often better because it means you aren't constantly spamming the input system / the server / etc.

[honest sky]

Just out of curiosity, if i have an Update, and i call a function twice within that update, does the function happen twice or only once?
i.e

void Update(){
  if(1 = 1) function1();
  if(2 = 2) function1();

i think its twice but since its per frame i dont know if it can be done twice per frame

[heady iris]

there is nothing special about Update

you'll get two function calls

(note that 1=1 is not valid syntax)

If that function MUST only run once per frame, I'd just move the logic to somewhere that only runs once

[honest sky]

ye i know i just put it as an example

also alright thanks

[thin aurora]

Why would it only invoke once? This is not how c# works 😄

[honest sky]

Ye im not sure why i thought that

[magic harness]

Hey boys. Need a quick fix for a problem im having right now.
I'm making a retro-style 2D RTS, and i have a map as an UI object, just an Image, sent on a world space canvas. On top of it i have some other screen-space ui objects.
I want to disable my mouse cursor clicking on the map when i interact with this other Ui objects. How would i approach this?

[heady iris]

how do you detect interactions with the map?

[magic harness]

Input.GetMouseButtoDown

[heady iris]

and then you read the current mouse position and do a raycast?

[dim hinge]

I Need someone that can help me making a unity battle system similar to undertale, there is someone? It will be very helpful, it's not that hard but i need help

[heady iris]

please don't repost the same question in several places

[magic harness]

no, i get currentMousePosition then proceed with the algorithm.

[heady iris]

The Algorithm? :p

[magic harness]

the program xD

[heady iris]

It sounds like you need to be able to detect when the mouse hits a UI element, and then bail out

[magic harness]

uhm... makes sense

[heady iris]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/script-GraphicRaycaster.html

this might be useful

a graphics raycaster can tell you what your pointer was over

[rustic ember]

I have this thing: cs [System.Serializable] public class Vector2IntEvent : UnityEvent<Vector2Int> { }
I use it in a script: cs [HideInInspector] public Vector2IntEvent onPositionChanged;
What is the correct way to add a listener to onPositionChanged? I get a red line under ChangeListeners when I put nothing in the parenthesis

positionHandler.onPositionChanged.AddListener(ChangeListeners("WHAT TO PUT IN HERE?"));```

[heady iris]

what is ChangeListeners?

[rustic ember]

A method

[heady iris]

is that the method that you want to call?

[rustic ember]

Yes

[heady iris]

then just pass it directly to AddListener

[magic harness]

i see. the problem is that i have these multiple canvas overplacing eachother

[rustic ember]

    public void ChangeListeners(Vector2Int _oldGridPos)
    {

    }``` It looks like this

[heady iris]

if you do this:

x.AddListener(MyFunction(/* ... */))

[magic harness]

so i have multiple graphics raycaster

[heady iris]

you're gonna try to call MyFunction, and then pass the return value from it to AddListener

which is void, in this case, which is impossible

[rustic ember]

onPositionChanged.AddListener(ChangeListeners());``` Is that not what I'm doing?

Oh

[heady iris]

Yes, you're trying to invoke ChangeListeners with 0 arguments

you will get an error

even if you gave it an argument, you'll still get an error, since AddListener wants a function that takes a Vector2Int

[rustic ember]

What argument do I put? I want the Vector2Int that is passed with the Vector2IntEvent

[heady iris]

(and you'd be giving it void)

[heady iris]

Nothing.

x.AddListener(MyFunction);

[rustic ember]

So I just delete the parenthesis?

[heady iris]

Right. You are not invoking ChangeListeners here

you are passing it as an argument to AddListener

if you hover your mouse over AddListener, your IDE should show you the type of that function

[rustic ember]

IIs that always the case with UnityEvents?

[heady iris]

This is how it works for anything that expects a function as an argument, yes

[rustic ember]

Alright

That makes sense. Thank you

[heady iris]

Functions can be treated like objects in C#

[muted sonnet]

for reference, a "frame" is not a thing in C#, it's just a basic loop that Unity runs

[heady iris]

we might say they're "first-class"

[muted sonnet]

there's nothing special about it

[heady iris]

meaning that they're treated just like any other types

in some languages, you can't just do something like

[honest sky]

Alright, thanks :)

[heady iris]

return SomeFunction;

functions are "special" in some way

[rustic ember]

Oh okay

Thank you for taking the time to explain

[heady iris]

in C, for example, you can't pass a function as an argument (you have to pass a pointer to a function instead)

[rustic ember]

What do you mean pointer?

[muted sonnet]

(well, in C# you do this too, function code isn't allowed to move for many reasons)

(you just don't hear about it)

[heady iris]

yeah

true
