It's triggering a cast filter that should be ignoring the layer that the other object is on. The cast filter in question focuses on the Collision layer, but it's triggering when colliding with the player layer.

[rancid sable]

I remember getting this error in my project randomly without using any of those methods when I was working on using the gui system, try restarting the editor

[marble swift]

im not using the find statement. im kinda new. is there something else i have to watch out for.

[dusk apex]

That should be the case unless he's really working with Editor scripts

[pure cliff]

do all three of em have the same issue?

[marble swift]

will try thanks

[river sentinel]

dunno. Only the players have rigidbody2ds.

[pure cliff]

all 3 of the casts I mean

[river sentinel]

and this is the physics2D settings:

[dusk apex]

If you aren't writing Editor scripts, it may be a false positive. A restart of Unity would fix the issue.

[hard viper]

I want an interface to force anything that implements it to have a specific static method. is there a way to do that?

[pure cliff]

lets start with the individual casts, which one is failing? all of em? ground? wall?

[marble swift]

thanks what do you mean with false positive?

[pure cliff]

you cant have an instance of a static method

[dusk apex]

Something went wrong

[somber nacelle]

not until c#11

[pure cliff]

wait what

[somber nacelle]

https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/tutorials/static-virtual-interface-members

[pure cliff]

holy shit brb I gotta go read about that one, thats zany

[somber nacelle]

it's how they implemented generic math. you can even overload operators with interfaces

[river sentinel]

just tested by removing gravity from the players and moving them over each other: both checks are triggering when colliding with a player layer object, without other collisions happening

so "all of them"

[pure cliff]

ahhhh, interesting

[hard viper]

I know. I want the class that implements it to have to have a static method that I can call without an instance

[pure cliff]

what I really want them to add at some point is a Self constraint one day

[hard viper]

and yes, it does make sense for it to be static.

[pure cliff]

like

public interface ISomething
{
   public TSelf DoAThing<TSelf>()
       where TSelf : Self;
}

and literally all the Self constraint is, is that the generic is literally the thing itself

[river sentinel]

@pure cliff I've been called for dinner, can we continue this after in DMs? Sorry about this. ^^'

[pure cliff]

I prefer not to do DMs, in case other folks have a similiar issue its good to be able to link em to it, and other people can chime in if they know an answer

thread might be more appropriate

[river sentinel]

ah okay. I'll make one real quick

[hard viper]

not really. more like
public static int DoSomeMathSpecificToYourImplementation(int x, int y);

[pure cliff]

to build on above: then if you implement:

public class Something: ISomething
{
   public Something DoAThing() {
       
   }
}

would vaguely satisfy the conditions. Something roughly like that I hope exists one day

[hard viper]

can I use public static virtual? and override?

[pure cliff]

whats the method you are trying to make

[hard viper]

I have an electrical grid. Certain types of course parts will take in input for a direction they are getting electrified, and output a new set of directions to electrify, which will have ints for intensity assigned to it (like a big Vector4Int).

shit needs a static method. do not need an instance

[river sentinel]

CastFilter incorrectly triggering

@pure cliff made the thread #1138613253971398666

[pure cliff]

whats your reasoning for that, so Im on the same page

[hard viper]

because it is going to be on a monobehaviour that does not need to be instantiated

if I have like a diode, I don't need an instance of a diode for the diode to tell me : if left, output right. If not left, ignore

that is tied to the definition of the class

[somber nacelle]

MonoBehaviour that does not need to be instantiated
well that can't possibly be correct

[hard viper]

and it should be

if I can make it static virtual, maybe that could work

[somber nacelle]

not possible. static methods cannot be overridden

[pure cliff]

strategy pattern

as it often always is XD

You're issue is you are trying to put this method on your class itself, but it has no need to be there

[hard viper]

well I have no need for it to be in an instance

[pure cliff]

You just need a single Dictionary<Thingy, ConductivityBehavior>

[hard viper]

you know, some of these functions are going to get big

[pure cliff]

A way to map between the two

[hard viper]

and each of these classes that implements this interface will need to be implementing other interfaces with more behaviours

[pure cliff]

what got you tripped up was that you wanted to put this static function on the class itself, but thats not necessary at all

[hard viper]

sir, if I make a capacitor script, I do not want definitions for what my capacitor does in 4 different files

[pure cliff]

just so I use the right lexicon, whats the class of your block thingies called

[hard viper]

TileMonobehaviour

[solid quarry]

bro nothing makes sense, I have a game object tagged, and yet there is no collision. My head hurts man

[somber nacelle]

https://unity.huh.how/programming/physics-messages

[solid quarry]

thanks

[pure cliff]

aight, so you basically want this:

public class ConductivityManager
{
    // Fill this however you need to
    private Dictionary<Type, ConductivityBehavior> BehaviorMappings { get; }

    public ConductivityBehavior For<TTile>() 
        where TTile: TileMonoBehavior
    {
        return BehaviorMappings[typeof(TTile)];
    }
}

@hard viper

And then ConductivityBehavior is just a readonly struct, and the really slick part is you can re-use em with params

Or even just have 1 single struct and its purely paramaterized

[solid quarry]

im fairly new to this so, as a student I want to be able to fully understand these code chunks before I absorb them into my games

[pure cliff]

And you just go

var behavior = ConductivityManager.For<MyConcreteTile>();

[solid quarry]

as of now this is what I have,

{
    public Rigidbody2D rb;
    public float jumpAmount = 10;
    public int jumpCounter = 2;

    public void Start()
    {
        jumpCounter = 2;
    }

    void OnCollisionEnter2D(Collision2D collision)
    {

        if (collision.gameObject.tag == "JB1")
        {
            Debug.Log("Jump Boost Obtained!");

            Destroy(collision.gameObject);

            jumpCounter++;


        }
    }

I have my item tagged aswell which is what confuses me

[lean sail]

#854851968446365696 so you know what to include when asking a question, and #💻┃code-beginner for this type of question. The link boxfriend gave you goes into MANY reasons why your code may not work

[somber nacelle]

1. use the CompareTag method to compare tags rather than string equality
2. go through the link i sent, it takes you through everything you need to check to make sure that collision messages will be sent

[solid quarry]

I just checked it out, ill take a look

[pure cliff]

@somber nacelle I am also now realizing those static methods on interfaces mean that implementing strategy pattern will now be a little bit easier, as you can map the relation between Strategy <-> Consumer without needing instances of the Strategies up front, and can instead build the map first and then load the strategies on demand lazily, thats slick

[hard viper]

so abstract/virtual static members of interfaces were introduced in C#11

so they are supported. but not for us

I figured out a workaround. I can just give the base class TileMonobehaviour the static virtual method.

I could try the strategy pattern, which is what I originally wanted, but some of this stuff is going to grow really wild, so I need to keep each part more centralized. I will keep that in mind tho

[pure cliff]

what do you mean by "grow really wild"?

[hard viper]

that class can have multiple methods in it

and I do not want the definitions to get very separated

[pure cliff]

You can put more than 1 method on your strategy

[hard viper]

again: I do not want to go to 4 different files to see the definitions of what a tile is supposed to do

[steady moat]

You can more than 1 strategy also

[pure cliff]

you... wouldnt

like for your FooTile, youd have a FooStrategy, and it would have 4 methods on that one FooStrategy class

[steady moat]

If you ever needs to have that much strategy, you might have over generalize your object.

Also, you can create a custom editor if you want to centralize the serialization of different parameters.

[hard viper]

I have a tile SO with a bunch of flags for a tile. It can have a prefab associated with it, it can have a monobehaviour tied to it. and several situations need all 3

which is why I want to keep actual script tied to one tile to one class

[steady moat]

I do not see the issue there. Flags are flags. It can be a list.

[hard viper]

I'll need to think this over for a bit

[steady moat]

If you have shared behavior, how would you "keep it together" ? You cannot define things in multiple class.

[pure cliff]

Are we talking about more behaviors in general and not purely just this conductivity problem now?

[hard viper]

the way he described it earlier was that I’d have a conductivity controller class which contains all definitions for all tile, which I am not doing

it could take references to functions. Having that map is ok.

[pure cliff]

Cuz I would say based on how complex your tiles are, I think you need to just get used to the practice of encapsulation and abstraction, it is not a bad thing at all for your 1 "thing" to be spread over multiple files, because that way usually leads to being able to re-use stuff and it means your principle "concepts" have been decoupled and encapsulated

[hard viper]

but I won’t make one mega file with all the functions for every tile in one scenario.

[pure cliff]

Im not sure what you mean here

[steady moat]

Maybe you are generalizing before needing it ?

[hard viper]

i’ll need to read more on the strategy pattern

my game requires a lot of generalization

[steady moat]

If you do no need multiple strategy, you do not implement the strategy pattern

Otherwise, you spread over multiple files

[steady moat]

Yes, however you should not feel like things are too spread out.

If so, you probably have overgeneralize.

It is like doing an interface for every interaction between classes

        } ```

[steady moat]

Also, ask your question

[stone scaffold]

i see

yh so im not sure why this code doesnt work, when i run it, the jumping animations dont trigger

[steady moat]

Probably because you set the bool to false the next frame

Use https://docs.unity3d.com/ScriptReference/Animator.SetTrigger.html

[pure cliff]

I would start by attaching the debugger and putting a breakpoint just inside the if (isGrounded) check, to verify you are at least passing that part

basically, putting the breakpoint on this line:

if (Input.GetButtonDown("Jump"))

[stone scaffold]

i was hoping that by pressing the spacebar, it would trigger the animator to set the "isJumping" bool

but it doesnt

im not sure why

[pure cliff]

if you never hit the breakpoint, then you know isGrounded is always false for some reason and your logic is off there

[stone scaffold]

i see

[toxic notch]

I'm using the XR interaction toolkit and I'm trying to get the interactor that is grabbing the grabbable object. I have it wired to an interactable event on the grabbable but when I look at ActivateEvents args, I see I have a args.interactorObject but that's of type Interface IXRActivateInteractor. How do I just get the gameobject?

[stone scaffold]

the only difference between the actual working code and this code however, is the fact that animator.SetBool("isJumping", true); is outside the second if statement

[pure cliff]

is your breakpoint getting hit?

[stone scaffold]

ohhhh my god

i see now

i see the problem

yes my problem was the logic on that line

Recreating chess.

I have a class ExplorationResult that has two public fields,
public List<Vector2Int> ExploredGridPositionList;
public List<Piece> HitPieceList;

• ExploreDirections() creates an ExplorationResult object and returns it.
  The ExploreDirections()is a general method and is potentially used for different usecases.

• Each chess piece needs to know where it can move, and where it can attack. Piece internally uses ExploreDirections() to determine this information.

Now,
I need to store this information, If i store it in an ExplorationResult variable inside Piece, I can simply look at ExploredGridPositionList to know where it can move, and look at HitPieceList to know where it can attack.

My question is,
Does it make sense to use the same type for both usecases? I feel like it is not very readable when using it for the second case, but also does not make sense (For example, class MoveSet) to create the same exact class with a different name to hold the same data.
What do i do?

[leaden ice]

I think this is a little over complicated. You probably just want a List<Vector2Int> legalMoves;

attacking and moving aren't really different things in chess

(yes pieces like Pawn can only move diagonally when attacking but that's ok)

basically - for each piece, calculate all the valid moves.

And if you're making an AI, then for all the valid moves for all the pieces, evaluate the board that would result, and pick the best position from those boards

that's the basic idea

[languid crane]

I've thought of only using the gridPosList, but im using the Explore method to just look for pieces too, so tried to make it generalized

Although, you're probably right, i can still use that class for the explore method but store the legal moves in a simple list i suppose

[leaden ice]

you don't really need to "look for pieces"

as long as you recognize that a board location with an enemy piece on it is a valid place to move.

[languid crane]

no no, thats for a different usecase of that method

in another usecase, i just needed to get a list of all the pieces hit by the exploration

[steady moat]

I fail to notice what are the two distinct use case.

A piece have a list of valid move. Those moves are either landing on an other piece or an empty space.

You want to know what pieces could be possibly be captured ?
You want to know what are the legal move of the current piece ?

[untold shard]

hello I'm something new, is there a way to imitate the grab, drop and throw objects from half life 2?

[steady moat]

#archived-networking

[nocturne sedge]

ah

[languid crane]

So what im doing is, each turn, instead of calculating every single piece's possible moves, i only do it for pieces that are relevant.

• To do this, I ExploreDirections() (all directions) from the piece that just moved (Both from it's old pos and new pos) and calculate the moves for the pieces returned by this method. First usecase.

• But to calculate the actual moves, for each of the the pieces hit above, each piece explores appropriate directions (Eg. Bishop - diagonals) using the same method ExploreDirections() to find where it can move/attack. Second usecase.

[steady moat]

Why would you want to know the legal move of the piece that are being hit ?

[languid crane]

because those piece's moveset could have been changed from the previous move

For example, consider this board

The bishop cannot move towards the bottom left direction because the pawn blocks

[steady moat]

To be honest, I would recalculate the whole board to reduce the possibility of error.

Each time it is needed

[languid crane]

But once the pawn moves, it can now move in that direction too, so its moves need to be recalculated

[leaden ice]

I don't see how it matters which piece most recently moved?

[steady moat]

Event base approach are risky

[languid crane]

@leaden ice This

[steady moat]

In other words, I wouldnt cache the result. It does not seem to be that expensive to calculate.

[languid crane]

My thought process is, at the start of the game, all piece moves are precalculated and stored.
Whenever a piece moves, a few pieces now have new moves available, so only those pieces are recalculated and stored, and the rest already know their precalculated moveset

[steady moat]

You are trying to hard to optimize a game that does not need to be.

Start by recalculating everything.

When it is needed

It will reduce the probably of incorporating bugs.

[quartz folio]

Chess programming is extremely well described, there is no need to innovate

[languid crane]

Thats fair, I will be trying to make this game multiplayer, so i'd like to have it optimized as much as i can, but not just that, i also see it as a personal exercise to try to write optimized code

If i ever encounter bugs with incorrect calculations, i can always switch to recalculating every piece's moves each turn or calculating when clicked on the piece or something, since i will only have to change when the calculation happens

[steady moat]

1. Make code that works
2. Make code that is clean
3. Make code that is optimize

(Keep those iteration relatively short)

Also, preemptively optimizing is most of the time a bad idea.

You want to be able to mesure the impact of your change.

That being, said, there is also a minimum to do.

By minimum, I mean, do not allocate 3G of data on the ram without having any other alternative.

In that case, we can even say that it does not work.

[hard mountain]

Yes don't disregard performance completely

Stuff like proper data structures should be taken into consideration at all times imo

[languid crane]

I understand, i did start out with those three steps and ended up here. The only reason i optimized this is to challenge myself, with the assurance that if something goes wrong, reverting is extremely simple since only the when code needs to be changed, but all the calculation logic still remains the same

[steady moat]

To some degree.

[steady moat]

If you want to challenge yourself, you gotta first measure how well things are running.

Then, see how you can optimize it.

This way, you are "data oriented"

[languid crane]

I completely understand your point, but i'd still like to have my original question answered incase i run into it under completely different circumstances,

In the case where a data structure with the same data needs to be used for multiple different purposes, what do you do?

[steady moat]

As per https://resources.unity.com/games/unity-e-book-optimize-your-mobile-game-performance

[steady moat]

You are asking if it is ok to use a function in two context. Yes, function are made for that.

[languid crane]

I am asking about the ExplorationResult class, not the ExploreDirections() method

[warm aspen]

do you mean like have a game manager object that stores data that can be accessed by any other object in the game?

[steady moat]

ExplorationResult is the result of ExploreDirections isnt ?

[languid crane]

yes

[steady moat]

Then, yes, it makes sense to use ExplorationResult in two context where you want to know about the result of the exploration.

[languid crane]

@warm aspen Here is my initial question

[hard mountain]

I'd make a separate class that stores the state in a static variable

There's also the scriptableobject route

[steady moat]

ScriptableObject wouldnt really fit here. We are talking about runtime data.

[hard mountain]

I use scriptableobject as data channel between classes a lot

[steady moat]

Also, the result is per piece I imagine, not really something you keep in static.

[hard mountain]

Hm

[steady moat]

That is different.

We are talking about stocking the result of the research of a piece after ExploreDirections

[hard mountain]

Okay i misunderstood then

[warm aspen]

I'm struggling to understand the issue

[hard mountain]

Whatever you proposed makes perfect sense to me, i don't know why you're considering making a new class

[warm aspen]

in the original question you ask if it makes sense to use the same method "in both cases". What both cases? In the question I only understand one case: the piece trying to determine which spaces it can move to and which pieces it can attack

[hard mountain]

Even if the cases are different i see no issue with reusing the same class

It still represents the same data. So maybe just name your class better to reflect what it is (though this is obviously hard to do)

[languid crane]

Not using the method, using the same Class: I clarify the cases question here

[languid crane]

So at the moment, each piece stores its moveset as an ExplorationResult variable, this is fine yes?

[warm aspen]

but wouldn't there be cases where the movement of a piece A affects the possible moves of a piece B even though B isn't hit by the exploration done by piece A?

[languid crane]

I couldnt think of a situation where that's the case. The only possibility of that happening is knights, to counter that i'm just recalculating all knights every single move

[warm aspen]

I agree with @steady moat that I would just recalculate everything for every piece after every single move

[warm aspen]

but what if the knight is the one that moved last?

[languid crane]

Yes, i will switch to that approach if i run into any bugs or incorrect calculations, it is a single method change.

[languid crane]

then that wouldnt be different from any other piece moving

[warm aspen]

his exploration might not hit some pieces that would be affected by his new position

[languid crane]

how?

Other pieces can only have new moves if

• The old position was blocking moves
• The new position now blocks moves

[warm aspen]

so if the piece that last moved frees a space for the other piece to move, how does the other piece know this unless it's hit by the first piece's exploration?

why try to optimize so much? A simple platforming game does more calculations than that every single frame, you would just do it once after every move

[languid crane]

because im exploring from the old position in all directions

[warm aspen]

oh, you explore from the old position and then again from the new position?

[languid crane]

yes, all the pieces hit from both those explorations are recalculated

[warm aspen]

Ok. Yeah, I see it. I still think it's overcomplicating something for almost no gain, but I understand now

[west sparrow]

I'm unsure why you are needing to calculate that. It would seem to me the only time a movement set matters, is when a piece is selected. So I'm unsure what the intent is myself...

[languid crane]

I've already explained above, just as a personal exercise to see how well i can do, and if something goes wrong, it is a simple change to recalculate after every move

[west sparrow]

Unless it's for the AI maybe. Not judging just curious.

[warm aspen]

I was assuming it was for the AI

[languid crane]

Agreed, Its just that when i started out i didnt know how expensive exploring everytime was, so simply cacheing the moves and referring to the cached value made 'logical' sense. (Not talking about if it makes practical sense)

[west sparrow]

It is always good to challenge yourself, and definitely learning about pathing systems and methods can be valuable

[languid crane]

I probably wont be working on the ai, but since i already have all this optimized work done, i dont see how reverting would be better (unless there is a flaw in my design ofcourse), reverting to calculate ever time is simply just making it less optimized (however tiny the diffence is) for practically no benifit, i feel

[west sparrow]

I do agree it's over complicating it, however, you likely would cache all the available moves in a turn and then assess the best path for a possible strategy (for an AI). I'd probably recalculate every turn, but if you did only calculate the differences, it could be used to assess a risk to the AI strategy.

I.e. an AI could tell easier from incremental movements if a strategy is at risk. But if going down that path, I'd strongly recommend reading up on any existing methods for chess AI

For PvP, I'd only calculate available positions once a piece is selected, and maybe everyone once a piece is moved (although you probably dont need that data). And probably use Events and Delegates to create a message if a global refresh is needed. So it only runs the calculation when absolutely required.

But off the hop, I'd only calculate the movement options for a selected piece on selection, and leave it at that. You usually don't need to know any other pieces moves. Unless it is AI, I think.

[warm aspen]

You could even just calculate if the move is valid once the player selects a target space

or when he hovers over the space with the piece selected

[west sparrow]

Yeah absolutely. I'd only precalculate it for highlighting

[warm aspen]

although you could give some visual feedback to show which spaces are free to move or to attack

[warm aspen]

yeah

[west sparrow]

Yeah exactly

Great 🧠 think alike:D

[crude mortar]

side note, it being multiplayer doesn't really have anything to do with the performance. The clients would be simulating the game entirely on their own, and only syncing simple commands like "opponent moved thing on a5 to b5" and they would do that move on their local machine to "sync"

but maybe you were referring to accessibility

[torn eagle]

Bit of a funky one but has anyone ever had issues with code running on a mac version of the editor but not windows?

When I made apk for android, I set the aspect to 16:9, but my phone runs it at 20:9 since thats my aspect ratio.
But when testing with Unity Remote it uses 16:9 but the UI is squished.

My question is, how can I fix the issue so its not squished when resized to 16:9 and how can I force it to use 16:9 even if my phone is 20:9(like adding black bars maybe if needed or perhaps resize UI somehow to match.

Canvas scaler:
https://i.gyazo.com/2ac58139b85a437de04fc3239f02774f.png

[hard mountain]

you can test out how it looks in 20:9 in the editor

right here

[upper pilot]

yeah but I dont want apk to work only for 20:9

nor do I want to test it on all possible aspect ratios

is there a way to make it scale automatically without stretching

[hard mountain]

maybe aspect ratio fitter and parent all elements to that?

[upper pilot]

Tbh I assumed my phone is 16:9, not 20:9 😄

[hard mountain]

you can also experiement with the Match slider, i use 0 most often

[upper pilot]

Yes it was at 0 before.

canvas scaler is the issue I think

cuz it uses 1920x1080 which is 16:9

[hard mountain]

you do need the scaler though, otherwise your UI straight up won't work for different scren sizes

[upper pilot]

ah ok found it

Match Scale : 1

[hard mountain]

nice

[upper pilot]

Because I am running it in landscape mode

Not perfect, but it looks better

[tired elk]

Hi ! Since you can't directly put a ternary in a interpolated string ($"{condition ? resultA : resultB}") since : ends the interpolation, would having a first string that stores the ternary result then interpolate be lighter/better than having a string.Format ? Purely informational, I currently have a string.Format.

[lean sail]

$"{(condition ? resultA : resultB)}
should work

[tired elk]

It does, thanks.

Hi!
I'm trying to control the animation controller via script with a single blend tree that has all of the poses. Since I do everything via script, I'm using a direct blend tree with no transitions.
I noticed that values seem locked from 0 to 1 (both in the inspector and using animator.SetFloat()). Is there a way to set a negative value with direct blending (I'm using a generic rig, not a humanoid either)? The docs doesn't say anything about a limitation like this.

[arctic tartan]

moving this to the animation thread*

[foggy pasture]

yo, is anyone aware of why i'd be getting this error

[tired elk]

What is the definition of Varyings ? Is it internal stuff ? It looks like it doesn't contain any uv field

[foggy pasture]

that's what i've been trying to figure out actually, it's a package so i'm trying to hunt it down

i don't know much about hlsl so i wasn't sure if it was a language thing

[lean sail]

#archived-shaders maybe..

Hi, I'm using Invoke to call a function. It works on the Start void but not when it's inside my custom functions, is there any way to fix this?

[hidden parrot]

Code? That's not really very much to go off.

[rich elbow]

void HitPrefect()
{
scoreManager.noteScore = "Perfect!";
Invoke("setNoteHitToZero", 1.0f);
}

void setNoteHitToZero()
{
scoreManager.noteScore = " ";
}
(HitPerfect is called when a key is pressed)

[vagrant blade]

You need to show how you're calling HitPefect

[hidden parrot]

Yeah, that and please use nameof

[vagrant blade]

Also they're called functions, not voids

[hidden parrot]

Are you actually sure HitPrefect is called?
Put a debug log in.

[rich elbow]

i did and it is being called

[hidden parrot]

Can you use nameof, might fix it, might not

The other thing I can think of is the invoke is being interrupted somehow, like the script being disabled, gameobject being disabled, something stopping all invokes, etc.

[rich elbow]

Thank you!

[topaz ocean]

is there an effective way to prevent elements of a vector3 from growing to a NAN

[fervent furnace]

why it will become Nan?

[topaz ocean]

im manually computing collision forces and im facing an issue where an object forced into collision accumulates infinite velocity

[fervent furnace]

by sum(mv) before=sum(mv) after?

[topaz ocean]

I used to use a float velocity, I just checked "IsNan" but now its a vector3

[knotty sun]

so do the same on each component of the vector3

[topaz ocean]

Ah, okay, I was just wondering if there was a better way

[knotty sun]

clamp the x,y and z values to float.MaxValue

[topaz ocean]

nah that doesnt work if the value going in is a Nan

AKA exceeding infinity

I presume because by definition of Nan it doesnt know whether its past positive infinity, negative infinity, or whatever

[fervent furnace]

i just wonder why the velocity will becomes infinity, the mass is zero?

[topaz ocean]

no, its because I base the depenetration force on a factor of the velocity, so it scales exponentially

[fervent furnace]

(*((int*)&some float)&0x7f800000)==0x7f800000

[knotty sun]

Vector3 v3;
if (v3.x + someFloat == Single.Nan) v3.x = float.MaxValue;

[fervent furnace]

or float.isnan

[topaz ocean]

I did it a bit differently, I just used a temp variable and based the axis assignment on whether the result is an NaN

so if nan then keep the previous velocity on that axis

[flat prawn]

I need to deserialize json into a Dictionary<string, object>.
Googles MiniJSON can do this, but contains native code and can't be used in WebGL builds.
Unity.JSonUtility and Newtonsoft does not seem to be able to this.
Anyone know of a solution?

[knotty sun]

How did you serialize the json in the first place?

[flat prawn]

Using MiniJSON on a Desktop build. So yes I would like to solve the inverse case also, serialize a Dictionary. But is not as important

[oblique spoke]

Pretty sure Newtonsoft can

[flat prawn]

I think I could use Newtonsoft JsonConvert.DeserializeObject<Dictionary<string, object>>(json); and the recursively go through the result and convert any JObjects and JArrays I find....

[knotty sun]

It's really just a question of looking at the json produced by miniJson and emulating it for another library

i mean json is json but you do need to understand it

[flat prawn]

I would prefer not to write my own json parser 🙂

[knotty sun]

no need to write you own parser. but you do need to understand the json strings produced

[flat prawn]

Nothing strange about the json. The problem is that the working deserializers are tailored towards targeting objects with fields directly, and not create a Dictionary

[knotty sun]

so you make it a 2 stage operation

[jade phoenix]

    public IEnumerator FadeOut()
    {
        var timer = 0f;
        while (timer < 1f)

            timer += Time.deltaTime;
            yield return null;
        }
    }```would anyone know why whenever i run this coroutine in one place, it works fine, but when i run it somewhere else it doesnt appear at all? the debug statements are being logged.

[void remnant]

What should I do when my vector is "too small" to be normalized. Is there a mathematical formula to normalize it by myself? I'm asking because .normalize returns zero

[rocky helm]

How do I correctly get all the vertices of triangles in a mesh (for simplicity lets say a cube) that look in the same direction as transform.forward? Right now, I have this code:```cs
public void CalculateFrontBounds(){
Mesh mesh = GetComponent<MeshFilter>().mesh;
int[] triangles = mesh.triangles;
Vector3[] vertices = mesh.vertices;
for(int i = 0; i < triangles.Length/3; i++){ //Loop through every triangle
int triangleStart = i*3;
Vector3 p0 = vertices[triangles[triangleStart]];
Vector3 p1 = vertices[triangles[triangleStart+1]];
Vector3 p2 = vertices[triangles[triangleStart+2]];
Vector3 triangleNorm = (Vector3.Cross(p1-p0, p2-p0)).normalized; //Get the normal of the triangle
if(triangleNorm == transform.forward){ //If the triangle is on the same plane as the forward facing face(s) is
AddNewPoint(p0); //Adds a new point if another point doesnt exist with the same position
AddNewPoint(p1);
AddNewPoint(p2);
}
}
}

Which, to me seems like it should work, but the problem is that ``if(triangleNorm == transform.forward)`` seems give me wrong results, but instead  ``if(triangleNorm == transform.up)`` gives me the vertices of triangles that look in the same direction as transform.forward, but even doing that doesn't work at all when I rotate the transform on the y or z axis.

Also, I noticed that mesh.vertices and mesh.triangles is 3x what they are supposed to be

Probably for like saving the uvs n stuff tho

[rocky helm]

I think you could multiply the vector by 1000 and then normalize it because that, I believe at least, should give the same answer

[hard viper]

I looked into the strategy pattern, and I’m already using it. TileMonobehaviours are classes tied to my TileObjectBase SOs, which are listed in a big dictionary class which just holds a bunch of dictionaries to tie the different TileObjectBases to tiles. Once it gets to my ElectricalGridManager, it already has a reference to the TileObjectBase, which has a field corresponding to its TileMonobehaviour type. I just needed to make sure that the TileMonobehaviour implemented a function for the conductivity behaviour strategy IF the TileObject has a flag saying to expect it to have that function implemented.

This is why I was confused with your suggestion

[void remnant]

thanks

[steady moat]

Comparing float is never a good idea.

[rocky helm]

good point

I'll try to round it up here float point problems shouldn't happen

[steady moat]

You should just use the sqr magnitude

with an epsilon

[rocky helm]

what? How could I use that to get the front face's vertices?

[steady moat]

if((triangleNorm - transform.forward).sqrMagintude < 0.01f))

[rocky helm]

oh like that, k I'll try it

[rocky helm]

that unfortunately still didnt change the outcome

[steady moat]

Not exactly sure what is the idea of the function

However, you are correctly itering the vertices

[proven path]

When I have a class or component which only needs one implementation, is it still a good idea to derive this class from an interface for the sake of programming to an interface instead of an implementation?

[rocky helm]

Actually, I think I have an idea how to solve my problem, but if I just compare which point is closer to another point, then couldn't I do ```cs
Vector3 posOffset1 = targetPoint - point1;
Vector3 posOffset2 = targetPoint - point2;
float distance1 = Mathf.abs(posOffset1.x)+Mathf.abs(posOffset1.y)+Mathf.abs(posOffset1.z);
float distance2 = Mathf.abs(posOffset2.x)+Mathf.abs(posOffset2.y)+Mathf.abs(posOffset2.z);
if(distance1 < distance2){
blah blah blah
}

instead of comparing the sqrMagnitudes in terms of speed?

Like would this work, or is there a problem with this?

And if it would work, then would it be faster than sqrMagnitude?

[steady moat]

SqrMagnitude is the Sqr of the Distance

There is no need to actually do the sqrt here.

Also, your distance calculation is wrong.

distance = sqrt(posOffset1.xposOffset1.x + posOffset1.yposOffset1.y + posOffset1.z * posOffset1.z)

Also, there is no need for 3 points. Only 2

Is it not possible for VSC colors and highlight to work properly when editing files from inside Packages folder ?

nvm i think i need to add assembly

[steel finch]

so I basically want to create a dungeon system for my 2d game with handcrafted rooms , can I use tilemaps to create each room prefab or would that be too inefficient

I'm asking this in the wrong chat aren't I 💀

[primal wind]

Tilemaps are for tiles

[steel finch]

interesting

So what is a good alternative then

[primal wind]

You could use it if your rooms are static but i guess they aren't so you'll have to make your own system

[manic gulch]

Hey there, I'm having an issue with animations right now
I've tried to add a new property to my animation clip, which is the sprite renderer of the "sprite" child object.

I've used EditorCurveBinding.PPtrCurve() to bind the property to the animation clip, more specifically this was the line of code that was being run

EditorCurveBinding.PPtrCurve("neph/sprite", typeof(SpriteRenderer), "m_Sprite")```

And yet it marks it as missing! Should I change `"m_Sprite"` or something?

[steel finch]

alr

ty

[manic gulch]

Welp, fixed this; the issue was that "neph/sprite" should be turned into just "sprite" only, because the path specified for the property starts from the first layer of children gameObjects. If it's left empty then you are referring to the parent object. Nvm

[pure cliff]

You use Strategy Pattern multiple times, its not a "one and done" sorta deal.

This is just another behavior/strategy if you will, "In what way does this electrify things" is yet another strategy to select.

Its quite common/normal to nest strategies in a tree, it forms a varient of a Behavior Tree effectively speaking.

Each time you hit a fork in the tree, that is strategy pattern, one is a subset of the other.

[pure cliff]

Its a good habit to be in professionally, I dont bother with interfaces on my data classes ("is a" models), but I always try and interface my services.

Makes mocking em up easier (btw, RIP moq D:)

Thanks, that sounds reasonable!

Wth does UnityEngine.SceneManagement.Scene.GetRootGameObjects() want me to give it as input? (https://docs.unity3d.com/2021.3/Documentation/ScriptReference/SceneManagement.Scene.GetRootGameObjects.html)

[leaden ice]

nothing

for the first version

but everything is pretty well described there

[rocky helm]

Then hy do I get this error? error CS0120: An object reference is required for the non-static field, method, or property 'Scene.GetRootGameObjects()'

[leaden ice]

because you are trying to call it statically

when it is not a static function

you need a Scene instance to call it on

"An object reference is required"...

You're probably looking for https://docs.unity3d.com/2021.3/Documentation/ScriptReference/SceneManagement.SceneManager.GetActiveScene.html

[rocky helm]

Like the current scene I am in?

[leaden ice]

if that's what you want

whatever scene you want to get the root objects for

[rocky helm]

oh, I though that SceneManagement.Scene did that for me, but I guess not

[leaden ice]

SceneManagement.Scene is just the name of the type

you need an instance of that type

[floral coral]

• what are the things you include at the start of a C# script called? (the using blablah.blah;)
• how can I make custom ones that work like a C++ library (as in, any script in the unity project can have using custom.name; and use functions from that like a C++ library)

[bleak thorn]

Why rectmask doesnt work properly on dark blocks?

[worldly hull]

C# will not include all libraries for a single script, cuz u wont have few hundreds line of code that will use all the C# function possible

[leaden ice]

1. using directives
2. using directives only are for namespaces. They are not the same as libraries

[worldly hull]

by default, only minimal libraries are included

[leaden ice]

If you want a "library" you make a .NET assembly or a Unity UPM package

[floral coral]

are there some tutorials for how to use them?

[leaden ice]

the only thing that using SomeNameSpace does is just let you write SomeNameSpace.SomeClass as SomeClass without the namespace

[floral coral]

no, I just want it to act like one

[worldly hull]

normally i will just have few static classes to hold some custom extension functions for me to use lol

thats it, enough

[leaden ice]

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

it's very simple

they're more or less just part of the class name

[floral coral]

I'm overthinking it

I want something like the raycast function, where you write physics.raycast(...) and the raycast does something in the scene, but something custom for my game like output.send(...) which a circuit in the game would use to output data.

[leaden ice]

I don't really understand this question but it sounds like you just want a static function

[floral coral]

and every circuit component would have a using GameNamespace.Output in order to access the function

[stark sinew]

Sounds like you want some kind of messaging layer between different objects?
When object x does something, you want to inform object y without directly talking to it?
Idk if that's the proper name, but I think it's called something like Event Bus (Pattern) or just a simple Observer, depends on what exactly you're trying to do

[floral coral]

no, no, the code for communication is in the function, what I want to do is have an arbitrary script (like an extra one from a mod for the game) to have access to that function

[ashen yoke]

so the question is modding?

[stark sinew]

Ok, the things (arbitrary scripts) that want to access that function could subscribe to the output.send thing which will then inform them when it's called?

[floral coral]

yes

[ashen yoke]

in most cases where you want code mods support you use Harmony and expose some base class/interface for mods to extend from

modders will reference your game dlls in their project, access whatever they need, use harmony patches to modify code when needed

the only thing from you that is needed is some entry point, mod handling, and certain code style that simplifies modding

[floral coral]

I don't know how to explain well what I want to do, and I don't know if what you're suggesting is what I want to do.

[stark sinew]

If you want (code) modding support for your game, that's probably the fastest way

[floral coral]

I think what my ideal for this game would be is to have all of the circuits in the game be made the same way a modder would make them (like a json for definitions and a c# script for the functionality)

[stark sinew]

What do you consider to be a circuit, could you give a small example with pseudo code?

[floral coral]

and then what the compiled game does is construct the parts at startup for example

[floral coral]

example for a "rotation reader":
json:

• model
• rotation axis, attachment point
• output rotation and location
  c#:
• read axis angle
• sent that value to output

[stark sinew]

Ok, I begin to understand.

Why would you want to separate data and logic into separate file(format)s?
That's just making it harder I guess, most mods or add-ons may have a json or xml file coming with it, but those are mainly informational, things like the version and name.

Also, there are some different approaches to do this on your own, but I'd say they are not easy to execute

[floral coral]

a json is easier to read/write, and expandable

[stark sinew]

But then, strip the C# File completely and have the C# logic live in your Game

And make the Json file store a function name and an execution Style

So your game reads those form the json and knows "ok, I should call X function with Y parameters in Z style"

Execution Style being for example Update, OneShot etc

[floral coral]

I'm inspired by scrap mechanic, where the json file is used to define static "values" for a part (name, color, placement type, and script location), and a ||(lua)|| script that adds the functionality for a complex part in the game

and the lua script can use the scram mechanic api to interact with the game world

[stark sinew]

That's probably because Scrap Mechanic has a LUA Interpreter included in it's Runtime, but not sure, never played.

I once tried to create generic modding support and ended up tinkering with my own ScriptingLanguage for months, that's another possibility.

[hybrid goblet]

You could read into melon loader to make your game available for modding.
If you want to do it from scratch, this is gonna be hard

[floral coral]

it uses a custom engine that isn't written in Lua, but that's off-topic

[stark sinew]

That Custom Engine could still include a LUA Interpreter/Compiler in it's Runtime, else it wouldn't understand LUA

[floral coral]

still off topic for what I want to do
I think*

[stark sinew]

It's not off-topic, you could do the same, include some kind of LUA Interpreter/Compiler in your game.

I think you're underestimating the work you need to do for modding support 😄

Options so far:

• Use Harmony
• Use MoonSharp
• Create a SL from Scratch
• Use a JSON that holds data about which function to execute with which arguments which would be handled by your Game

The last one would be the easiest as of now, if you understand the concept, but also the most limited.

Example of how Cities: Skylines did it
https://skylines.paradoxwikis.com/Modding_API
The game ships with a C# compiler which allows for automatic script compiling at game start.

Including a Interpreter or Compiler is the way, if you use a pre-existing one or create your own is up to you.

Even the JSON Approach would basically need some kind of Interpreter

[fluid tapir]

Hey there, does anyone know which IK solver does the Unity Two Bone IK use?

[floral coral]

on that note, Logic World (also made in unity) uses C# scripts for modded parts.
I know some sort of interpreter or compiler is needed.
I've observed that I pretty much always get stuck at how "things" communicate with each other (script with script, json to script, ...lua interpreter with script)

[stark sinew]

For a simple scenario, they wouldn't communicate with each other, your game would read the mod and understand what it says.

The mods could be limited to using only the pre-existing building blocks that your game provides.

Each building block would just be an ID and a function call that takes a variable count of parameters.

I'd love to give you a concrete example, but I'm on my phone and typing code on it s.... hard.

I'd advise you to fiddle around with writing a simple interpreter and VM from scratch, that'll deeply improve your understanding of the process that happens behind the scenes when you write and compile a script, it'll definitely help with understanding how Code Mods work.
It's not too hard, don't become intimidated!

[floral coral]

that's like writing visual scripting

Each building block would just be an ID and a function call that takes a variable count of parameters.

[stark sinew]

And? 1st, it's not, it's less flexible then Visual Scripting, but 2nd there are full blown good games out there that solely rely on Visual Scripting, so it's definitely good enough for modding..

Eventually you could start a thread to further talk about the modding "issue"

I'll give you an example for a pseudo JSON file

FunctionID: ModifyPlayerHealth
Parameters: 1
Execution: Update

or

FunctionID: 
CreateEnemy

Parameters:
GetRandomEnemy
GetRandomPosition

Execution: WorldLoad

of course 90% would be strings, it's JSON, you gotta interpret those strings and find out if they are meant to be functions or whatever else, basically you need to Tokenize the JSON into your own format before Interpreting it

FunctionID: AddCustomEnemy

Parameters:
myEnemySpritePath
someAttackValue
someSpeedValue
etc...

Execution: GameInit

[floral coral]

yeah, but then you have to add every function, and probably use all of them in the game.

In order to make something other people can use to create new stuff, you need to have some way to do extra computation, like math and control flow, so you would make a function for those, and then boom, you have a stupid json interpreter

[stark sinew]

Yeah, that's why it's called Modding SUPPORT, you gotta support it.. 😄
It's up to you what the user can and cannot do with their Mods, it's tedious but you have maximum control, also it's easy

If you don't want a stupid JSON interpreter, then utilize, as already stated, an existing solution like MoonSharp or Harmony, or create one from scratch.

I'm out, sorry, I've given enough information on the topic, not much more to say.

You'll get it done if you try, definitely, would be happy to see the results!

[floral coral]

Yes, I know, I already stated I know that.
I'm gonna dig further into moonsharp

[pure cliff]

@floral coral Lua is popular for C++ games, I know that, as there's a lot of solid "ready to use" libraries out there that effectively let you define a C++ function but then expose it as callable from a Lua wrapper.

Another option you can do for C# are plugins dlls, where the user must create a .dll of their own that meets specific criteria (has a specific method exposed on a specific class or etc), and then they drag and drop it into a specific folder and your game scans there looking for "recognized" .dlls that match the requirements.

[gray mural]

I have a game that allows player to create a levels and give them names. I save those levels into json file. What is the best way to call those json files? Just the name of the level that has to be unique, the name that is generated by custom ToJsonName method that deletes all spaces or int id?

[swift falcon]

Hello. I am using Addressables and it returns Asset as an "Object". Does boxing happens there since its a base class of Y?

public virtual Object Asset;
x.Asset as Y;

[leaden ice]

I would probably name the files with the name the player gave the level.
Another option is to just use a UUID as the filename and put the level name in the json itself, but it would make it harder for users to copy level files around manually if they wanted to

[gray mural]

Do I have to parse those names?

[leaden ice]

anything that is an asset you can get with Addressables is going to be a reference type. There won't be any boxing, they're already reference types

[leaden ice]

parse what names

[gray mural]

My nice level blabla => Mynicelevelblabla.json?

[leaden ice]

you would have to parse the json to get the level name in the scenario when the level name is part of the json.

if it's the filename then you just grab the filename

[gray mural]

no, json will contain actual level name

[leaden ice]

I would probably also give them a .mygamelevel file extension for example too

[gray mural]

why..?

[leaden ice]

for fun?

to identify them as level files for your game?

[gray mural]

well, they will be in specific folder

[swift falcon]

Oh! I read something like "Boxing is exists for only value types" i understand now that well. Thank you.

[gray mural]

Assets/#Levels/MyLevel.json

[simple egret]

Helps the user in avoiding drag-dropping completely random json files, if their extension is the same

[gray mural]

when you download a game, do you have an access to all scripts??

[leaden ice]

alternatively when theyre sitting on some website or distributed through discord wouldn't it be nice if they have a custom file extension so you can identify them?

[leaden ice]

no

[gray mural]

well, probably..

wait, no

it doesn't matter

they won't have an access to file itself

they will be able just to view a level in the game

with already instantiated items

so it doesn't really matter

[leaden ice]

you don't want your players to be able to share level files with each other? You know they'll go looking for them

if you're saving them as json files they will be able to do this

[simple egret]

Yeah what's the point of a level editor and storing these in files if it's not possible to distribute them?

[gray mural]

probably though the game?

like "share my level with foobar123"

[leaden ice]

sounds like a lot of work for you

you'll need a whole friend system, user login, authentication, etc

[gray mural]

well, I have done the basics already

[leaden ice]

and then users will still complain "Why can't I just give a level file to someone"

[gray mural]

yes, I have done authentication already, it is stored on another branch of my git

[gray mural]

well, I think I will make them able to download levels from the link?

also I have created level system for the host for now

so no authentication rn

just levels that are created by host

But does it make sense to generate an id in format AvJ12SPfa3AN139SaP13Hy98 ?

[quaint rock]

well how do you want to generate the ID

it really should be some sort of checksum of the contnet

[gray mural]

well, a for loop with e.g. 20 iterations first

and generate A-Z, a-z or 0-9

quite easy, right?

so it will be AvJ12SPfa3AN139SaP13Hy98.json

[quaint rock]

but why that instead of it being based on the real content

or using a established method of getting a globally unique id

[gray mural]

for example?

[quaint rock]

like a SHA256 checksum or a GUID

depending on if you want it based on the content or just want a ID that will not clash with a other generated id

[gray mural]

well, there can be several names with My nice level name probably

[gray mural]

an id

[quaint rock]

i am talking about all the content

like the checksum would be for the entire contents of the file

[gray mural]

I will probably just create a method that creates a unique id

[quaint rock]

then would use the built in GUID then

[gray mural]

and the level should be found by its it..

[gray mural]

but can I control what it generates?

if I want just A-Z, 0-9

[quaint rock]

why do you need to control that, dont you just need a ID that never clashes

[gray mural]

if the players will find levels by id, then I want to control that

[quaint rock]

ok and what happens when the same ID is generated twice

[gray mural]

new id is generated?

[quaint rock]

ok so your intent is to check the database every time a ID is generated

[gray mural]

while (listOfAllIds.Contains(id))
    GenerateSmth();

[quaint rock]

and hope its never done concurrently

[gray mural]

it won't be done concurrectly I guess

also the chance for it to generate the same id among billions of combinations at the same second isn't that high

[quaint rock]

i am likly just thinking at the wrong scale, am used to dealing with databases that can get rather large

and where i would want to ensure the same thing is never stored more then needed

[gray mural]

well, I will do that without a database first

also thank you all for your help 😄

also 10 letters (A-Z or 0-9) is 3,656,158,440,062,976 combinations

pretty reliable

[quaint rock]

it might end up with things ids larger then you want, but this would be a nice way to always get the same ID from the same input file

public string CheckSum(string filePath) {
    using var sha256 = SHA256Managed.Create();
    using var fileStream = File.OpenRead(filePath);
    return Convert.ToBase64String(sha256.ComputeHash(fileStream));
}

[gray mural]

so if 8 billion people play this game, the limit of levels each person can create is 457,019

[quaint rock]

obviosuly could format in otherways that are not base64

[gray mural]

can I control string's length?

[quaint rock]

why i mentioned it might get longer then you want

[gray mural]

yes, I see no problem in creating my own one then 😄

[quaint rock]

its main advtange is, its gives the same ouput for the same input file

and can be used after the download to verify the contents are what was infact requested

[gray mural]

yes, but there can be a few levels with the same names

[quaint rock]

it would not compare the name, but the whole level

[gray mural]

there can be 2 absolute identical levels

[pure cliff]

thats what GUID does :p

if you are storing in a DB though, with a server, your database should handle what ID is assigned

when a player saves the level, the server will tell them what ID they were assigned by the database after it has been saved

[wintry crescent]

Hi, I have an object that has a script, and a trigger collider - and the script does not register callbacks. This is solved, when I add a kinematic rigidbody to the script. This is caused by the fact, that a parent object has a rigidbody, so all callbacks go to that object. Is there a way I can override this behaviour on a case-by-case basis without adding kinematic rigidbodies?

This is a work thing, and I'm forced to use a framework, and one of its features is that it turns all rigidbodies on certain objects into non-kinematic ones under certain conditions... it's more stupid than I can express with words, but I can't do much. It's how the system was made, it wasn't prepared for my usecase.

which is why I don't want to use rigidbodies

[river sentinel]

Trying this again, this time with a minimized project with only the integral details pertaining to my issue: I have a script which is triggering a cast filter on the incorrect object.

Player objects have a component called "TouchingDirections" which has three bools: IsGrounded, IsOnWall, and IsOnCeiling.
IsGrounded should be true when the player is touching the FloorColl layer.
IsOnWall and IsOnCeiling should only be when the player is touching the Collision layer.
Players touching other players should not be making any of the casts.

All objects colliding with the player are triggering all casts anyways.

[wintry crescent]

what's your script?

and, assuming you're using unity collider collisions what's your layer collision matrix?

[river sentinel]

oh whoops didn't mean to send that yet. I'm prepping a small project to show off the problem, one sec.

Scene: CollisionDebug (if the player objects are invisible just pop the Square sprite onto their child sprite renderers)

The physics2D settings should only allow collisions between Players and FloorColl, and Players and Collision. Not Players and Players. Yet for some reason, it is.

the weird part is I have another project where a similar script is used but this problem isn't a thing. And I don't know why that is.

You'll need to move the "players" via the editor btw

[wintry crescent]

I'm installing this unity version, but I read up on some documentation already
do you have proper layermask set up in your ContactFilter2D?

[river sentinel]

there's two contactfilter2ds. groundFilter should only be checking the FloorColl layer and wallFilter should only be checking the Collision layer

if it's not then something went wrong when zipping but that's how it's set up on my end, so that's not the issue.

[dark sparrow]

Is there a way to blend the animations in a blendtree?
As you can see, its just changing direction instantly without smoothly transistioning

[main shuttle]

Yeah, they are called BlendTrees https://docs.unity3d.com/Manual/class-BlendTree.html just like you said.

[dark sparrow]

That is also what I am using

[wintry crescent]

I got the issue! Spot the difference:

[main shuttle]

So what is the question then?

[wintry crescent]

it works with that change

[dark sparrow]

@main shuttle It does not look smooth, it just cuts to the new direction

[river sentinel]

Of course it was something ridiculously simple as a checkbox flattens

thank you

[wintry crescent]

no problem! Happens constantly to the best of us

[topaz ocean]

is there a way to have a script-sided gameobejct? something that doesnt actually exist in the scene but I can assign components to?
I need to preserve transform axes of the object I have this script assigned to, so it would be helpful to be able to handle transforms in a nested object. I would prefer not to require an actual child gameobject for this script to function.

[oblique narwhal]

Don't think so - but many of the constituent members of a GameObject can be ... so if your just looking to deal with its Transforms you could have a private Transform as a member of a class that is not related to an instantiated game object

[topaz ocean]

if I also have a private collider can I assign that collider the private transform?

[oblique narwhal]

Well you can certainly have a private Collider or Collider2d as a member of a class.

Having both private Transform and a private Collider would not be the same relationship as if they were attached to a gameobject though.

Usually you would do something like:

`
public class MyGreatClass : MonoBehavior
{

private Transform myTransform;
private Collider myCollider;

public GameObject myPrefab;

private void Start()

{
var go = Instantiate(myPrefab);
myTransform = go.GetComponent<Transform>();
myCollider = go.GetComponent<Collider>();

}

}

`

[topaz ocean]

well I would like to orient a script collider with a script transform to use computePenetration on, I would have to add together the transform position and script transform though

[willow minnow]

i have few issues with my code, that i just dont understand how to fix. so one, the object that is tracing towards me needs to stop like 10 feet behind me, and im not sure how to do that, two, the object needs to start moving immediately, ive noticed it only starts moving whenever i stop moving, and three, i need a better way for the object to know im not looking at it. i was thinkin raycast but i havent seen any good way to do it online

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

public class CatController : MonoBehaviour
{
    public Transform target;

        [Range(0, 1f)]
        
        public float Range = 0.5f;
        [Range(0, 5f)]

        public float Speed = 5f;
  
        void Update()

        {

        transform.LookAt(new Vector3(target.position.x, transform.position.y, target.position.z));

        float viewGap = Vector3.Dot(transform.forward, target.forward);

        if (viewGap > Range)
            {
                transform.position = Vector3.MoveTowards(transform.position, target.position, Speed * Time.deltaTime);
            };
        }

}

[oblique narwhal]

Yeah .. sorry not really fully understanding your use case - but given best answers I can.

Its possible that Unity's way for you to do this is to really use the real gameobject in question - and you are going to be homebrewing something very custom.

[oblique narwhal]

Maybe change:

`
float viewGap = Vector3.Dot(transform.forward, target.forward);

`

to

`
float viewGap = Vector3.Distance(transform.positon, target.transform.position);

`

[willow minnow]

doing that makes him move when im looking at him, instead of the opposite

[oblique narwhal]

Sorry had to adjust my code sample, I didnt adjust the variables inside the Distance check at first

[willow minnow]

now he moves the entire time

[oblique narwhal]

Well your default value for the movegap is very small ... .5f

Depending on the size of the following object and the object that you are comparing it it might be that any movement at all easily falls in to your .5f range?

[willow minnow]

well, the object is a cat, and ill up the range, see what happens

so nothing happened, i up-ed the range, and the cat kept moving the whole time, and then i went back to the original script, and nothing changed

[oblique narwhal]

So reading your code .. the pseudo code I would write for it (exposing the intent) is:

1: Look at the target
2: Calculate a "viewgap" which is the distance between the object and the target
3: if the distance between the target and object is greater than the specifie drange then move forward.

With that being said it seems to make sense (if the above check outs)

The only other thing I'm seeing as note is you might be mis-using Vector3.MoveTowards.

https://docs.unity3d.com/ScriptReference/Mathf.MoveTowards.html

The docs here are very weird - they are assigning the output to a currentStrength float, whereas you are assigning it directly to a transform.position . I'm not sure what the intended behavior here really is.

I'm not by any means sure that is your issue - but call it out because I don't understand what it should really be doing - so its at least worth looking at a bit?

I say this is weird because a transform.position is a Vector3 - but this function outputs a float.

So your assigning a float to a vector3 somehow - not sure what that does for movement - but maybe it does weird things and keeps moving?? 😄

[simple egret]

(you picked the wrong link - Mathf.MoveTowards does operate on floats, Vector3.MoveTowards on vectors, but they essentially do the same thing)

[oblique narwhal]

Thanks for catching that didnt see theres more than one type for that function.

Then I retract my statement 😄 not sure what is going on - possibly some other behavior affecting whats going on??

[willow minnow]

for the little nudge, i think it might be something to do with the model and physic stuff

but it should be fixed if i can get the follow to stop a bit behind me, but i got 0 clue on how to get it to stop at a certain distance behind the player model

[oblique narwhal]

Well theres manual control and physics systems.

It looks like you are manually controlling it otherwise you'd be doing something like rigidbody.AddForce or such.

So in the manually controlling area .. I would think just stop telling it to move and it stops

[willow minnow]

i know, i can set it to stop. i just dont know how to set it to stop when it gets to a certain distance, but at the same time, i dont want it to stop behind a wall im next to just because its close to me actually

[umbral agate]

Respected, is it possible to stop the particle system immediately when user don't touch the screen..

Is there a way to display an array of strings as an enum-like dropdown selection list in the editor window?
To be exact, I need a single string variable, that is displayed as a selection of a few specific options from an array of strings.
I have a list of item names that I want to choose from in the editor (Specifically in a node in a dialogue system(the image), that redirects the conversation flow depending on if player has or doesn't a certain item in their inventory).

Normally I'd just make a simple enum and be done with it, however, my list of items is being loaded from a file, and it is, naturally, expected to change during the game's development. Keeping enum in sync with it would be a pain, and leaving the parameter in the node be a string field (as it is now currently) opens possibility of bugs and errors due to typos.

[leaden ice]

Write a custom inspector or use NaughtyAttributes or Odin

[swift falcon]

Is there a way in unity for me to add to what happens when prefabs are made?

Like if I create a prefab could I have it create an SO in the same place and populate it with the data of the prefab?

Not been able to find anything but I think I found a way to add my own "Create Item from prefab" button in the context menu, so I can right click the prefab and then make the SO from it.

I will work on this for now but if anyone knows of a way to automate this on prefab creation, please let me know! Thanks

[lunar kestrel]

Does anyone know why when I put [SerializeField] and [Range()] on my privat variable, it doesn't keep the values after entering play mode? It seems like SerializeField doesn't work

[somber nacelle]

are you sure you aren't reassigning the values in Start or Awake?

[unreal valley]

What's the code look like?

[lunar kestrel]

[SerializeField] [Range(3,6)] private float number

[lunar kestrel]

.

[unreal valley]

Bunch them together with a Comma

[SerializeField, Range(3, 6)] private float number;

[warm aspen]

Are you sure you're not assigning another value to this variable somewhere else in the code?

[light rock]

this is unecessary FWIW and wouldn't cause any bugs one way or the other

[agile night]

I was making some custom gravity modifiers to make the jump of my character feel nice. It works, however there is some funky stuff going on...

There are two gravity modifiers, one when the character is going up (jumpGravity) and another when the character is going down (fallGravity) If the character is standing still, there should be no gravity modifier (it would be set to 0)

But then, even when the character is not moving, the gravity modifier is set to fall gravity instead of 0 for some reason.

And then some funky stuff goes down when dragging the character while in play mode...

[lean sail]

are you sure the debugs line up with what you labelled them to be? Id add some text to ensure this like $"Gravity modifier: {gravityModifier}"

[agile night]

(Although i shouldn't be doing this to begin with i guess)

[agile night]

Yes, but i'll do that just for sharing reasons.

[lean sail]

your character is likely just adding a ton of speed over and over, since your velocity would rarely hit exactly 0

think about the case where you are falling. your speed is negative, and in SetPhysics you are constantly adding gravityModifier * Time.fixedDeltaTIme
Regardless if its not moving because its stuck against an object, its still gonna add

[agile night]

aight, thankyu brother!

[agile night]

It's calculated automatically based on the desired height of the jump, and the time it should take to reach that height.

I should put a vertical speed limit tho

[mossy valley]

How do I make an animation for a UI element that can be used by any other UI element irrespective of their position. Cuz right now, whenever I try to make an animation, it uses their global position so all of the elements with that animation get thrown to the same position

Or is it better to just code the animations?

[prime sinew]

I would suggest you use DOTween instead for UI animating, if possible. Sorry I don't know the answer for your direct question

Ah, yes. Code the animation!!

[mossy valley]

Ahh okayy thank youu, will try DOTween

[prime sinew]

The documentation has examples too, so it's pretty easy to pick up

I suggest you get the hang of DoTween sequences. Very useful

i literally tried this

[tired elk]

Your code works fine. Where are you calling BuildMesh ?

[void remnant]

What is better/More performant?

[proper flume]

go to mesh generation thread

[lean sail]

maybe delete that and write that R properly for ontrigger.
I also dont know what "where--" is but the one on the left only stores 1 list but accesses it through a reference (i assume). The one on the right stores a list per other class, and presumably uses an event to send that collider. If you're checking for performance in time, this is something you'll have to profile yourself or benchmark.
In terms of memory, its kinda obvious

oh those are brackets

[void remnant]

Sorry. So, on the left you have a manager class that stores every collider it interacts with and the dependent classes each filter the colliders they need. On the right you have a manager class that just fires an event, and the dependent classes each have a list where they can add the colliders they need through if statements. I'm more so asking what is better to use in the situation where there are a few tens of "other class" objects and one manager class. I don't know how Linq .Where() works. Maybe it's fast enough to call it on every onTrigger event. Because without .Where(), I will have to handle the storage and removal of colliders in each dependend class, which is annoying

[lean sail]

it'd be worth profiling still if thats a concern. 10s of classes really isnt much.
You are looking at a time-memory tradeoff basically, do you want 50 classes each storing a list, or 50 classes to filter through a list.
If accessing the list a LOT, I would go with the one on the right, where you filter if you should add a collider as you get them. If rarely accessing the list, id go with the one on the left

[void remnant]

alright thanks. Imma do the left implementation because I'm lazy. If my potato laptop will lag, then I will have to do the right one

[upper pilot]

[unreal valley]

So i have a dilema where I want to be able to call this only 1 time but be able to "refresh" i guess would be a lack of a better word, the PASSIVE Abilities Buffs if say the level got changed.

I've been trying to think of how to not put it in Update, cause that will just call the passive buff to be added over and over again. Not really sure how to implement this without someone basically looking at all my code?? I would assume.

TLDR: I want to "use" the passive ability ONCE but keep the Buff rolling infinitely.

Snippit of what I was calling in update to test VVVVVVV

GetAbilitiesFromCurrentJob().Find(x => x is PassiveAbility && !x.BuffsBuffsCanStack).Buffs.ForEach(x => x.ApplyBuff(Character as Player));

What im currently also trying in Start to test VVVVVVVVV

private void Start()
        {
            foreach (var ability in GetAbilitiesFromCurrentJob().Where(ability => ability is PassiveAbility && !ability.BuffsBuffsCanStack))

Why does ur vector3 only have 2 coordinates

[proper flume]

Because this is not Roblox

Well

Idk bro but a vector 3 seems to have 3 coordinates to me

A vector2 has 2 coordinates

[fiery hill]

A Vector3 with 2 coordinates sets Z to 0 as default...

[rocky helm]

Does InverseTransformPoint also take into consideration the transforms rotation?

[late lion]

Yes.

Position, rotation and scale.

[visual basin]

Ight

[thin aurora]

If you use a Vector3 without explicitly defining a Z axis, you might aswell use a Vector2

I think that was the point being made

[proper flume]

But this is not roblox

I dont want to

[thin aurora]

What does Roblox have to do with any of this

[proper flume]

In roblox you have to set all 3 numbers

But roblox is trash

Roblox is trash because they force you to set all three parameters?

Hi there. Let's say I have an Abstract Class Ennemy that inherits from monobehvior. I have several different script that inherits from Ennemy. How can I store the reference of an Ennemy Script on an object.

GetComponent<Ennemy>() does not work (because Ennemy is an abstract class) so what is the solution ?

[scarlet viper]

        foreach (Transform folder in folders)

is this as fast as array?

[leaden ice]

GetComponent<Ennemy>() will indeed work

[leaden ice]

not quite but almost

[fervent furnace]

get abstarct class will work

[scarlet viper]

is it possible to see the mechanism that makes it work? maybe in Tranform.cs ?

then your object doesn't have any Ennemy scripts on it

[scarlet viper]

thank u

I knew exactly where to look and what to look for

[karmic rose]

So I have this class:

public abstract class BehaviorTree : MonoBehaviour

And some class inheriting from it including this class:

public class SpikeBoiBT : BehaviorTree

I attach SpikeBoiBT to the root parent of the ennemy object.

On one of the child object of the ennemy object, i have another script with :

    BehaviorTree BT;
    
    private void Start()
    {
        if(!transform.root.gameObject.CompareTag("Player")) BT = transform.root.gameObject.GetComponent<BehaviorTree>();
        Debug.Log(BT.name);
    }

The Debug.Log return a NRE.

Is there something I missed ?

Oh nvm I am a idiot --'

thanks for the help though 🙂

[fervent furnace]

the debug.log will always run

public void Categorize(int index)

when u press a button u can make it pass integer or string or something to an OnClick public method
is there a way to make it include itself ?

I don't know if this was the right channel to do this in, but I have this wierd issue with robot kyle where he is just not rendering any of his textures in. How do I fix this?
Image

[leaden ice]

looks like you're using a material that isn't supported by your render pipeline

e.g. you're using a BIRP material for URP or vice versa

(or perhaps no material at all)

[muted cave]

I use android based type build. Also: it does have a texture on it. It has robot kyle's.

[leaden ice]

textures are not the problem

^reread this

android is also not relevant

[leaden ice]

you need to answer calrifying questions

what render pipeline are you using

what RP are those materials from

Use a shader on the material that is supported by your selected renderer pipeline. To get further help take it out of this channel.

I agree with ClampMagnitude, its better for when you have analog input

[leaden ice]

doesn't matter

[proper flume]

mesh.vertices = new Vector3[]
{
    vec1,
    vec2,
    vec3,
    vec4,
};```
Can someone explain this? This Vector3 somehow accepts 4 vector 3's

[leaden ice]

this is an array

Vector3[] means "array of vector3s"

[proper flume]

ohhh okay

[leaden ice]

arrays are basically a fixed-length list of things

[proper flume]

How do i add something to an array

[leaden ice]

arrays cannot be added to - they are fixed in length. You must create a new, larger array, with the new elements in place as you wish

[proper flume]

what i googled it it says .append

[leaden ice]

that's python

this is C#

[proper flume]

Add To Array Using Array. Append() Method C#

??

[leaden ice]

doesn't exist afaik

[proper flume]

what

[leaden ice]

and if it did it would create a new array

[proper flume]

it was literally aut orecommended

[leaden ice]

by who

[proper flume]

vsc2022

wait just vs 2022

[leaden ice]

Are you talking about https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.append?view=net-7.0 ?

This is a Linq method

it's not part of the array type

[leaden ice]

and it will not return an array, it will return a new IEnumerable

returns a new sequence that ends with element

not an array

[proper flume]

what

[leaden ice]

try it and see

[proper flume]

then is there something i can store variables in and add things to it

[leaden ice]

A List

[proper flume]

Ok i changed it thanks

vertices.Add(vec1);

vec1 is Vector3(0,0) by the way

help pls

[main shuttle]

Initialize the List

[leaden ice]

looks like you never created your list

[proper flume]

List<Vector3> vertices;

I did

[leaden ice]

this is not creating a list

this is a variable that can reference a list

[proper flume]

what how do i make it then

[leaden ice]

but it is not pointing at any actual list

List<Vector3> vertices = new List<Vector3>();

or the shorthand version:
List<Vector3> vertices = new();

[proper flume]

Thanks

What does collection is of a fixed size mean

[west sparrow]

Thats an array. It has a specific size by design, to change it would mean creating a new array.

Hence why it was said you can't append to the same array, as it is a fixed size.

[lunar kestrel]

still sometimes variables reset to their previous state

[whole gull]

can someone help?

[rigid island]

what is SceneView ?

[whole gull]

I want to have sprites that act as billboards but only in sceneview

https://docs.unity3d.com/ScriptReference/SceneView.html
https://docs.unity3d.com/ScriptReference/SceneView-camera.html

[rigid island]

this is a editor only function

[whole gull]

i want to use it only in the editor

do i have to declare my script somehow that its editor only?

[rigid island]

this wont work in game export you know this yes?

[whole gull]

yes

[fervent furnace]

#if UNITY_EDITOR

[lunar kestrel]

and when i add the range it disables somehow serializefield

[leaden ice]

yes indeed. - #archived-code-general message

[whole gull]

@rigid island I'm using this for invisible objects that have logic, for example an object that acts as a spawn position. Instead of using the unity label gizmo thing (which I find very ugly), I want to give these things Icons which I can see in the scene view, but ingame its not relevant

[wintry crescent]

You're trying to access a non-static thing in a static context
You need to first get a reference to the current scene view like that
SceneView.currentDrawingSceneView
And then that will have a camera for you

But yes you need to wrap it in #if UNITY_EDITOR or your build will crap out

[whole gull]

thanks guys

[rigid island]

alrighty

you can assign custom icons to gizmos too iirc

[whole gull]

LOL

you are right! 😄

omg

[whole gull]

I will do that instead 😅

[whole gull]

I have a really stupid problem, I have a shotgun which fires multiple pellets. When the pellets hit an enemy, they call the "TakeDamage" function. Inside that function I checked if Health is below 0 and call the "Die" function. When the enemy has low hp, all pellets cause the if to be true and "Die" gets called multiple times, which is a problem... I can't think of a cool solution other than having a flag if "Die" was called already and just dont do anything if a "hasDied" flag is true... (does this even work?)

When all pellets call this function, do these run concurrently? Or does Unity have a call order internally?

[somber nacelle]

only one line of code will be running at a time. using a bool to flag whether it has died or not is sufficient

[whole gull]

in that case, how is this possible? I destroy the gameobject in the die funciton

i guess destroying happens on the next frame?

[somber nacelle]

correct, calling Destroy just queues it up to be destroyed. it won't actually be destroyed until the end of the frame

[whole gull]

why is a flag not sufficient?

I mean i dont like the solution anyway but i thought it would

oh

sorry

I misread your comment

alright, I guess I jsut do that for, maybe im stupid and thats the completely right solution anyway 🙂

[fervent furnace]

i have met some simliar problem finally i realize thare maybe multipe callback from physics engine

so you need a flag to lock it

in your case i think you can lock it by if(hp<=0)early return;

[whole gull]

true!

[plucky knoll]

The code is meant to set a create a network object and set it as a child of the clients, but it only works on hosts, it spawns the object in fine for all clients but when it comes to making it a child the clients get an error of “only the server can reparent network objects” I’ve tried everything go get this working with rpcs to get the host to do this on clients behalf but all it does it make that client parented on the hosts side too(what I wanted but I also need it parented for the client) I’m completely out of ideas to fix this please help

It’s literally killing me, 3 days trying to fix it now and nowhere I look online I can find an answer that works anything I try makes it more broken than this ^

[leaden ice]

#archived-networking and mention which network framework you're working with

[plucky knoll]

Sorry

[merry sierra]

hi so currently i have a car with wheel collider, whenever i try to change the cars location like reseting cars locations then it goes to the resetted location and comes back to the original location in a split second do anyone know why its happening

[leaden ice]

what other components are on it

[merry sierra]

rigidbody is there

[leaden ice]

what if you make the RB kinematic, then teleport it, then make it not kinematic again

[merry sierra]

that thing is also not working

input.gameObject.GetComponent<Rigidbody>().isKinematic = true;
        yield return new WaitForSeconds(1);
        input.gameObject.transform.position = spawnPoints[input.playerIndex].position;
        input.gameObject.transform.rotation = spawnPoints[input.playerIndex].rotation;
        input.gameObject.GetComponent<Rigidbody>().isKinematic = false;

this is what i am doing in courotine

it works in editor but not in build

[hidden gulch]

i was searching how to simulate AI FOV and i found someone using these lines of code:

        var toPlayer = (player.transform.position-transform.position);
        var angle = Vector3.Angle(transform.forward.normalized, toPlayer);
        if(angle<FOV/2)
        {
            //raycast to see the player, but thats irrelevant to my question
        }
```could anyone explain to me why is the fov divided by 2 in this code?

[burnt crypt]

how do you deal with the fact that people can load your game in dnspy and edit the sources

if its online

[leaden ice]

you ignore it because who cares

[burnt crypt]

you get cheaters otherwise

if you ignore it

[leaden ice]

if you have an online competitive multiplayer game you use a combination of server-side validation of player actions and ever-more invasive client side anticheat software

[burnt crypt]

people can fly just under any serverside anticheat while still gaining an advantage

[merry sierra]

i think when you divide the fov by 2 u basically get the ray in center of the current view

[burnt crypt]

ive seen a unity plugin for an anticheat. it was really bad, i could just disable it lol

[leaden ice]

Cheating and cheat detection is a never ending arms race. What do you want to hear?

that's the reality

[hidden gulch]

what

[burnt crypt]

i want to see how you guys deal with it. i reversed a game recently where the guy paid for an anticheat plugin but the fact that c# compiles to bytecode ruins all security

[merry sierra]

find the mistake i tried this

        cars[input.playerIndex].GetComponent<Rigidbody>().isKinematic = true;
        cars[input.playerIndex].transform.position = spawnPoints[input.playerIndex].position;
        cars[input.playerIndex].transform.rotation = spawnPoints[input.playerIndex].rotation;
        yield return new WaitForSeconds(1);
        cars[input.playerIndex].GetComponent<Rigidbody>().isKinematic = false;

and it worked

[leaden ice]

he is using a pathetic anticheat if it can't detect a simple attack like that.

[earnest gazelle]

I have a problem with addressable assets when building the project. It is completely OK in the editor.
There is a collection list with 90 elements. They are SOs. It is OK in the editor as I mentioned but in runtime, it logs 360!!! and then I get an exception exist same key because they are populated into a dictionary

[burnt crypt]

let me see if i can find it

https://codestage.net/uas/actk/

[leaden ice]

if it worked wdym about finding a mistake

[burnt crypt]

i guess a lot of it falls to proper integration of the anticheat plugin

[proper flume]

does Collection is not fixed meaning it has to be a list?

[burnt crypt]

it would be good if you guys could write all core anticheat stuff in c++ and properly compile it

[leaden ice]

what? Maybe share the code and the full error message you're seeing

[burnt crypt]

cause in c# i can just modify event handlers for when a cheat is detected

[merry sierra]

basically the center of the screen so that you can measure the side angle and do stuff according to it
like if your fov is 120, half is 60 and then you can do like if angle < 60 do something and andle > 60 do something this is what i think not sure

[burnt crypt]

clientside at least

[proper flume]

    }
}

wait why is it addrange lol

[merry sierra]

basically switching the position and undo the kinemetic directly after changing the position is making my car to go back to the original position but adding the small delay after undoing the kinematic part gives it some time to reset the position that i think what is happening right now

[leaden ice]

why are you doing triangles.AddRange(triangles)?

[proper flume]

i guess it was aut orecommended and i didnt notice it

[leaden ice]

int[] triangles < triangles is an array

as we told you before, arrays are fixed length

[proper flume]

no

[leaden ice]

they cannot be added to

[somber nacelle]

you have a local variable with the same name as your list field

[proper flume]

triangles is a list

[leaden ice]

no

it's not. You have another variable that is a list

[proper flume]

List<Vector3> triangles = new List<Vector3>();

[leaden ice]

with the same name

[proper flume]

oh yea

wait

[leaden ice]

int[] triangles) this takes precedence

in the method

[proper flume]

when i use vertices to make triangles

am i supposed to make the list a vector3 or int

[leaden ice]

triangles is an array of integers

they are indices into the vertex array

[proper flume]

can i add arrays to lists?

[leaden ice]

AddRange will let you add all the elements of any IEnumerable to a list

[proper flume]

no i changed it to add

[leaden ice]

if that's what you mean

[proper flume]

it was a accident

[leaden ice]

if it's still an array you can't use Add OR AddRange

if it's a list you can use either

[proper flume]

no its a list

[proper flume]

why when i try to add it like this

its saying that its a int[][]

when its supposed to be int[]

[somber nacelle]

seems like triangles is now a List<int[]> considering you're adding an entire array to it

make sure it is a List<int> and use AddRange rather than Add to add all of the elements of the array to the list

[proper flume]

it literally

doesnt let me to

[somber nacelle]

prove it

[proper flume]

oh it just did

yet my code

still doesnt work

[somber nacelle]

exactly. the reason it didn't work before was because you were calling AddRange on the local variable that just happened to have the same name as your field

[proper flume]

using System.Collections;
using System.Collections.Generic;
using System.Linq;
using Unity.VisualScripting;

    void CreateShape(Vector3 vec1, Vector3 vec2, Vector3 vec3, Vector4 vec4, int[] trs)
    {
        Mesh mesh = new Mesh();

        mesh.vertices = new Vector3[]
        {
            vec1,
            vec2,
            vec3,

        vertices.Add(vec1);
        vertices.Add(vec2);

    }
}

so im trying to make it so i can make 2 of these triangles

and so it saves both of them

because right now one of them dissapears

like its overriding the whole mesh

oh wait

i forgot to call the function

lmao

[mystic imp]

Why is Health false?

[somber nacelle]

do you have a component called Health

[proper flume]

i got a error

[somber nacelle]

what is line 49

[proper flume]

mesh.Clear();

this is line 49

[somber nacelle]

then mesh is null

[mystic imp]

How I can fix it

[proper flume]

what how

[somber nacelle]

do you have a component called Health

[proper flume]

how is it null

[somber nacelle]

where do you assign it? hint: you don't

[proper flume]

void CreateShape(Vector3 vec1, Vector3 vec2, Vector3 vec3, Vector4 vec4, int[] trs)

[somber nacelle]

again, local variable with the same name as your field

please learn about variable scope

[mystic imp]

No

[proper flume]

public class TestGenerator : MonoBehaviour

Mesh mesh;

its not local

[somber nacelle]

it is because you redeclared it on the line you call new on

Mesh mesh = new Mesh(); has nothing to do with your field of the same name

Why does this not work

Its supposed to do the exact same thing as before

Make triangles then save it and make it 1 mesh

[gray mural]

well, what if mesh is null?

[proper flume]

it makes a new one

[gray mural]

does it throw you the same error?

[proper flume]

theres no errors

the script simply not working

[gray mural]

I see, it calls UpdateMesh in Start

but what is not working?

[proper flume]

its suppose dto make triangles

as you can see in create shape function

then the vertices and triangles are stored in a list

then the mesh is created in the update mesh function

but the mesh is not visible

i dont even know if it exists

but all I know is that all the settings are correct cause the earlier code worked

[gray mural]

what was the earlier code?

[proper flume]

this

but this didnt update the mesh

so it only allowed for 1 shape creation

i need multiple of it

[somber nacelle]

and how are you rendering this mesh?

[proper flume]

what

mesh renderer

and filter
