ah ty

[cobalt gyro]

is key remapping doable without the new input system

[lapis egret]

If I want to pre-calculate the effect that manipulation of a parent object will have upon its child object, how would I do so?

[rain minnow]

yes, should be a tutorial somewhere on it . . .

Is there a way to hook a debugger onto Unity so I can get a stack trace of my code executing when I hit generate for my procedural terrain? Every time I generate a 100x100 terrain, it takes 15-20 seconds just to execute, and I wanna see what's taking so long as when it comes to the final game the map is going to have a 1kx1k map, which when I tried generating took 30 mins.

I hooked VS into Unity using debugging and also using the Unity profiler, but can't see anywhere the info that I need to see how long each process is taking

[rain minnow]

turn on deep profile and sort by the cpu time . . .

[lean sail]

https://docs.unity3d.com/ScriptReference/Profiling.Profiler.BeginSample.html
you can measure with this too

[fleet shell]

I've had deep profile on, how do you sort though?

[lean sail]

just saying as well, 100 * 100 is 10,000. While 1k * 1k is 1 million. If you can notice lag when doing 10k, 1 million wont be feasible

[fleet shell]

Yeah, I think the issue is with my noise map generator, as it has a lto of calculatiobs it has to do, which means I am probably gonna have to chunk it up and hope that it works out. Though I am still curious as to what process is actually taking the longest

[lean sail]

with this u can probably get a good idea

[cosmic rain]

Share some profiler data with us.

[rain minnow]

https://docs.unity3d.com/Manual/ProfilerCPU.html#hierarchy

[fleet shell]

Well bugger, those 15000ms executions don't look fun

[rain minnow]

now switch the Timeline to Raw Hierarchy . . .

[cosmic rain]

That
Thought I can already see that CalculateNormals takes a lot of the CPU time.

[fleet shell]

Oh wow, that's surprisingly useful

That's my calculateNormals

[mossy snow]

I like the part where you copy the entire triangle buffer, get a single int out of it, and then throw it into the garbage ... 3 times, per triangle

[cosmic rain]

Getting triangles from the mesh buffer is pretty heavy. You might want to get and set them once instead of doing it separately for each triangle.

[leaden solstice]

I’d blame Unity for bad API

[fleet shell]

I'd assume just getting them, setting into an array and then referencing the array each time would work fine?

[cosmic rain]

Yes. Though remember that you need to set the whole array back to the mesh after all the changes.

[fleet shell]

Alright, here's to hoping that clears up some of it at least

[leaden solstice]

You can use GetTriangles with pre made List to avoid allocation

I'm trying to make an inventory, but I'm having a little trouble. I thought about making a parent class and having a bunch of children inherit from that parent, that way I can create a list of "items" but I'm not sure if thats the best way to go about it. Any tips?

[urban orbit]

Guys, please help. I've been stuck on this for days. How can I achieve the touch drag movement from this following video considering that when you drop a block between two nodes it snaps to the closest one? https://youtube.com/shorts/pWCITdNGxEs?feature=share

[mighty yew]

make the blocks always check to see if they're at a "good" location, and if not, move them towards the closest good location

[urban orbit]

but how do I make the touch drag movement?

[mighty yew]

what do you mean by touch drag movement?

[urban orbit]

individual drag movement with touch input for each block like in the game

[mighty yew]

Oh i'm not a mobile developer so i'm not really sure how the inputs for touch screens work, sorry.

[urban orbit]

it's okay

[unique cloak]

If a gameobject with a script attached is destroyed using Destroy(this.gameObject);, and the attached script has some code in the Monobehaviour Update() method, is there any chance that the script might run the update method after the gameobject is destroyed? Or more generally does the script keep executing after the gameobject it's attached to is destroyed?

[cosmic rain]

If it's already executing, it will keep on executing until it returns. Otherwise, update shouldn't be called on objects marked for destruction.

[unique cloak]

Can I return monobehaviour update i.e.

void Update() {
  if (condition_to_be_destroyed) {
    Destroy(this.gameObject);
    return;
  }
}

[light rock]

yes

[fathom geode]

I'm struggling with some seemingly simple math and was hoping someone could point me in the right direction
I've got values X and Y that always need to be 0.1 apart, relative to percent Z (from 0 to 1)

ie, if Z = 0, x = 0, Y = 0.1,
if Z = 1, X = 0.9, Y = 1.
Where I get confused is how to express this linearly, so Z can go from 0 to 1 without clamping on either end

[lean sail]

calculation:
X = Z, if z > 0.9, x = 0.9
y = x + 0.1

[cosmic rain]

Yes.

[unique cloak]

Cheers

[unique cloak]

This except it should be y = 1 - x

[lean sail]

???

[unique cloak]

Nevermind ignore me

Im just confused haha

@fathom geode you mind me asking what the math is for?

Seems like an odd calculation

[fathom geode]

Extruding a spline based on percent, length needs to stay constant

[lean sail]

i was imagining its some start/end point, like a scrollbar

[unique cloak]

oo cool

[lean sail]

just to add onto the calculation: ideally you would do this
if z > (1 - difference)
x = 1 - difference
so you can adjust the difference to be anything without having to recompile the code everytime

[fervent jacinth]

how do i make a cube go between theese two points like a line renderer?

i already have the two points as vectors

[west path]

idk if this is the right channel but does any knowif this package is broken https://github.com/Whinarn/UnityMeshSimplifier/wiki/Mesh-Simplifier-API#constructors

[ashen yoke]

(a + b) / 2

or * 0.5

[fervent jacinth]

how do i turn that into a rotation

quaternion euler?

[ashen yoke]

what you turn into rotation?

[fervent jacinth]

i already have the scale of the cube working using the distance between the points, but how do i angle it so its in between them

[ashen yoke]

i dont understand

you keep piling up more and more things in your question

scale, angle

draw another picture with what you actually want

[fervent jacinth]

heres a really bad drawing

like you would use a line renderer

so the front of the rectangle is on one point and the back is on the second point

[ashen yoke]

you want to stretch a box along a line?

transform.forward = B - A

[fervent jacinth]

thanks so much, i made that way more complex then it had to be 🤣

[cobalt gyro]

🗿 sans = transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform.gameObject.transform;

[ashen yoke]

try this

        new GameObject gameObject => gameObject;

        private void Start()
        {
            gameObject.transform.position = new Vector3();
        }

just save before it

or better dont do it

[dense estuary]

Did you ever find a solution?

because if not I might see if I can animate the camera my self, but I'm not sure if that'll work.

[ocean oasis]

I've got a weird one. I wanted to make some simple soft body stuff, so I followed a tutorial and it's perfect. But now I wanted a script to make it grow with time. For whatever reason, when growing, the soft body springs just totally let go and pretend like they dont exist. Video link for the soft bodies: https://www.youtube.com/watch?v=W3x143cYF88&start=197

[patent quiver]

Hello I'm currently working on a player selection system to allow players to view each other's names and stat values(HP/MP). I'm trying to use raycasting to detect player tag, but this only works properly for the client that is running the server.(which doesn't quite make sense to me..) For other clients, the detection field is way off the player model but is somewhat constant, it's as if there's an invisible box above the player model that can't be adjusted. I'm using Fishnet for networking.

Here's part of the relevant code.

    {
        if (Input.GetKeyDown(KeyCode.Tab))
        {
            DeselectPlayer();
        }
        
        Ray ray = cam.ScreenPointToRay(Input.mousePosition);
        if (Physics.Raycast(ray, out RaycastHit hit))
        {
            if (hit.transform.CompareTag("Player"))
            {
                NetworkBehaviour clickedPlayer = hit.transform.GetComponent<NetworkBehaviour>();
                isHover = true;
                if (clickedPlayer != null && clickedPlayer != this && Input.GetKey(KeyCode.Mouse0))
                {
                    SelectPlayer(clickedPlayer);
                }
            }
            else
                isHover = false;
        }


        if (selectedPlayer != null)
        {
            UpdatePlayerInfo();
        }
    }

    public void SelectPlayer(NetworkBehaviour player)
    {
        if (selectedPlayer == player)
            return;

        selectedPlayer = player;
        UpdatePlayerInfo();
    }```

[mossy valley]

Any idea or resource that could help me with making a Daily Quest system

[lean sail]

i dont see anything thats really networking related that would make this work differently between server/client, you might have better luck in #archived-networking or pinned channels in there. Also this code doesnt really show too much of how you define where the names/values show

[elder flax]

How would I use Astar pathfinding to kind of see if a cell is connected to another cell in a group of hexagon cells?

to clarify each 2d cell is a different object (with colliders and disabled rigidbody) and when a cell gets destroyed (killed) then i want to check all the cells and see if they are connected by another cell, if not the rigidbody should be enabled and it would float away

or is there some other algorithm/way to do it

[mellow sigil]

That's not really a job for A* (or any pathfinding algorithm.) You already need to know connections before you can do pathfinding. You just need to check all adjacent coordinates, if none of them has a cell in them then it's not connected to anything

[elder flax]

yeah but the issue there is that cells could be connected to more cells so like

if you break a support an entire section could disconnect right

[mellow sigil]

ok well a group of cells is different from "a cell"

[elder flax]

oh yeah i didnt really mention that did i oops

[mellow sigil]

You could try a flood fill algorithm, if it doesn't fill everything then there's a disconnected section

[elder flax]

good idea

[patent quiver]

Alright I will try. The issue doesn't seem to lie within the names/stats retrieval though. Since the object detection in the first place is working weird..

[ashen yoke]

you dont keep connections in the node?

as references

[elder flax]

no

the 'swarm' controller on the parent stores all of its cells

ive just implemented a flood fill algorithm to search for disconnected cells that I can just call whenever a cell is destroyed

So I've made a state machine to handle game logic. Currently I'm not using any inheritance, and I'm instead trying to handle state specific entry and exit behaviour by calling functions in other objects. The problem I've found however is that this doesn't offer enough control, and instead I'm basically having to write the same code I would have done if using inheritance but instead it's in scattered in different places which is definitely worse. Any advice? I'm currently planning on just switching to inheritance

[sturdy pagoda]

thank you for actually writing the code my guy

it works perfectly now

[steady moat]

I just copied Google -_-

[sturdy pagoda]

oh well in that case id actually want to redact my thank you

im jk

[sharp acorn]

How could i go about copying images from window's clipboard?

[steady moat]

You would need to search for windows specific feature/library

[sharp acorn]

I found that if I put the System.Windows.Forms.dll file in the project folder, Unity does the rest, but I cant find the .dll xD

[craggy veldt]

why you want winforms in Unity 😭

winapi is your best bet here

[night storm]

is it bad for performance to have a coroutine permanently running this?

IEnumerator MyCoroutine() {
while (true)
  if (myQueue.Count > 0) {
    // things here
  }
  yield return null;
}

it checks if a queue has items in it each frame and idk if that is bad

[wind palm]

Do you need it every frame, also, why bother with a coroutine?

[ashen yoke]

no

[livid sandal]

Hello i have several question regarding collider2d i'm not sure if this is the right place to ask but here it is

1.) I Have 2 boxCollider2D 1 in MidevalKnights and 1 in Weapon ( as in the image )
2.) however i only have rigidbody on the MedievalKnights

Expected:

• when collider in the Weapon is hitting an enemy "Weapon is hitting an enemy" i damage them

Problem:

• When my player boxCollider hit an enemy it is also count as weapon hit which is not expected, how do i differentiate between these 2 colliders? Thanks in advance

[night storm]

yeah i need it running every frame in the background so it can immediately detect when the queue gets something added to it

[ashen yoke]

coroutines that are suspended are cheaper than updates, coroutines that are executing each frame like yours, are just slightly cheaper than update

[wind palm]

But FixedUpdate (50 checks per second) vs Update (which could be 140+ time per second), not many things need to be that instant.

Networking I can perhaps understand why Update (every frame).

[ashen yoke]

you are trying to solve something that is typically solved with events/observer pattern

[livid sandal]

i am using delegate events on the WeaponHandler so the trigger is not actually in the MedievalKnights itself

[night storm]

i suppose i could make it in update now that i think about it but if its cheaper ill just keep it this way. i just wanted to know if it keeping it this way is bad for performance, apparently its not bad then, thanks!

[livid sandal]

so how do i properly handle these kinda thing?

[wind palm]

Have you tried using layers? Then it's a simple check what's colliding with what.

[ashen yoke]

what is processing collisions? enemy/player?

i guess player deals damage

then you need to relay events to the root for processing

[livid sandal]

ouwwh that make sense but i also wanted my player collider colide with the enemy

currently i dont set include layers to anything in both of the collider

[livid sandal]

the one that process -> trigger is from weapons the one who process the calculation is the player

[ashen yoke]

this is what i do

[livid sandal]

maybe i should make the trigger and the calculation in the enemy instead? :/

i have been stuck here since yesterday XD

[ashen yoke]

set of interfaces ICollisionEnterHandlerRelay etc
implemented on root

on the colliders are components CollisionRelay

they have field target, of type monobehaviour

when they receive a collision event from unity they cast the target to the interface, if cast is valid, the method is called

[livid sandal]

im really sorry i'm new to unity so i have might not understand what you are talking about XD

[ashen yoke]

ok, what should i explain

or i can simplify the approach

simply have public void OnCollisionFromRelay(Collision col) on your root player controller

[livid sandal]

private void OnTriggerEnter2D(Collider2D other)
{
if (onHittingTarget != null) onHittingTarget(other);
}

Basically i wanted to know what collider is hitting with the "other" collider

[ashen yoke]

so the code on your colliders/triggers becomes

private void OnTriggerEnter2D(Collider2D other)
    {
        _medievalKnight.OnTriggerEnter2DRelayed(this, other);
    }

[livid sandal]

ohhhhh rightttt we HAVE THISSS

this

right let me try

XD

oke this works

i dont know if this gonna be costly or not tho

[ashen yoke]

no

[pure cliff]

Layers.

You can specify layer masks for collision detection on colliders, so instead of hitting everything and then filtering off, you can just avoid generating unwanted events in the first place

You should have a "PlayerVulnerable" layer which contains hitboxes for stuff that hurts player (enemies, ebemy abilities, enviro), and the players "vulnerable" hitbox.

Then "EnemyVulnerable" layer which has the enemies body hitboxes, and the players attacks or whatever and any other stuff that can hurt enemies

Theoretically also a "neutral vulnerable" layer if needed, if you need effects that hurt both players and enemies (like bombs or whatever on your game)

This let's you have stuff like enemies that have "non vulnerable" portions of their hitbox.

[crystal dagger]

Heya

I have a body and head separated

But when i try to apply transform effects to it, nothing happens

Only general transforms applied to "kkkxd" work.

[sleek bough]

Is this a code question?

[crystal dagger]

well quite

I'd like to know if there is a way to move it still being a child

maybe an option that i can mark i don't know

I tried looking for this everywhere in the manuals and google and etc

[sleek bough]

Nothing related to code. It has to be attached to the armature I think. So ask in #🔀┃art-asset-workflow how it can be fixed

[crystal dagger]

sorry for continuing it here but

so you mean i can fix that through blender normally?

[sleek bough]

Probably. I'm not that familiar with modelling. You should ask in appropriate channel for that

[crystal dagger]

Well, it's working fine on blender and animations. The real problem is that the transform does not apply to it. I think it's working just fine as a model

[sleek bough]

[mighty yew]

I'm trying to make an inventory, but I'm having a little trouble. I thought about making a parent class and having a bunch of children inherit from that parent, that way I can create a list of "items" but I'm not sure if thats the best way to go about it, because ill have like 100 or so files at the end of development that are just items. Any tips?

[crude mortar]

Your only other option is making items get constructed completely via the inspector using a very data oriented approach (or in code as functions). It would be one item class that has all the necessary information to construct any item type you want. A health potion would be a Usable and it would perform a Health modification when used, for example.

I think this approach is hard to design for and you are probably better off having a different script for each item if you want specific functionality. It is easier to understand and refactor as long as you don't make huge hierachy chains (like Item -> Weapon -> RangedWeapon -> Bow -> MyBow)

[steady moat]

Keeping your hierachy depth low is the way to go as stated by @crude mortar.

[placid obsidian]

Hiya, probably a weird question -

I want to take a gameobject(green thing) and move it based on the hitpoint of a raycast towards the red square ive drawn, how would i go about getting the direction and coords to transform it?

[floral onyx]

Hello Sir, I'm trying to do a fuzzy sugeno method here, so I'm applying the method to the enemy, here is the link of the full code:

https://paste.ofcode.org/SfgSLQqLrMmBgqw3CD5A3b

The core code is in the function of EnemyAttack(). The output is NaN, what is seems to be the problem?

[mighty yew]

There likely won't be more than a layer of depth, but im curious about this inspector approach. While it does sound interesting, my main issue is that in my game every item will have a relatively unique function. ie: one item increases health, another increases damage, another causes your attacks to explode etc. etc.

[crude mortar]

yeah, so it may not be worth making it extremely modular if you know that most things will be very unique in function

[leaden ice]

Start debugging

find where the NaN starts
usually it'd be from divide by zero somewhere.

[crude mortar]

modularity is harder to setup and provides benefits later, but if you never get to that "later" (in terms of reusing stuff) then it's pointless

[mighty yew]

alright, so one parent class is the way to go? is there a way to have multiple children per file cause honestly im just dreading creating dozens of files with like 9 lines of code in them each lol

[crude mortar]

don't dread that

more code on the screen does not mean that the code is somehow better or more reusable

I usually try to go for exactly what you are dreading—many small files. If you don't need much code to make things work, you are probably doing something right

[spring creek]

Hitpoint has a vector3. Just move to the vector
https://docs.unity3d.com/ScriptReference/RaycastHit-point.html

[floral onyx]

The problem is from inference system, the third step of my method.

[crude mortar]

and yes you can have multiple children per file if you wanted

I think as long as they aren't a Unity object

[floral onyx]

https://paste.ofcode.org/3b73KHdJZVLb7ZFUdAycZGm

This is the code, If I change the number, it will work, but it's not inline with my research

[crude mortar]

I believe Unity checks the filename for serialization purposes and so multiple per file would break it

[leaden ice]

this is 131 lines of code

[floral onyx]

Yes

[leaden ice]

find where you're dividing by zero

and stop doing that

[crude mortar]

maybe one or two parent classes, depends on your needs

[mighty yew]

but there won't be like, an issue with making a hundred files from a storage/speed perspective? i feel like that many files might lag the project?

[crude mortar]

I mean it's really the amount of code that matters

which you can't get around

[mighty yew]

alright i guess, thats fair

[crude mortar]

just my generic library of stuff I like to have in every project is hundreds of files, and that's before I even start the project

it is not that much slower than having a blank project

[floral onyx]

So the cause it's number/0, right?

[leaden ice]

that is what dividing by zero is, yes

it's when you divide by zero

[simple egret]

Oh lord I just clicked the link to the script
What a terrible day to have eyes

[floral onyx]

Ok, thanks, but what if it's required you to divide it by zero? I mean, if the output is 0 and that output is to be divided by other output?

[crude mortar]

computer can't divide by 0, so you must not do it in your code

you can check for division by 0 and stop it before you tell the computer to do it

[leaden ice]

it is never required to divide by zero. It's a nonsensical operation

[simple egret]

Dividing by zero is not defined, even in real life math

We don't know what it does

[spring creek]

It's mathematically ambiguous what that even means. How many times can 0 go into, say, 2?

[floral onyx]

I tried to change this method to codes, I do exactly like the formula.

[leaden ice]

"How big will each slice of cake be if I divide it into 0 pieces?"
"How many pieces of cake will we get if we cut it into pieces of size 0"?
This is what divide by zero is asking, and it's meaningless^

[simple egret]

Seen Animation vs. Math by Alan Becker? At some point it tries it and you visually see why it fails

Subtract 0, infinitely

[crude mortar]

well formulas are not programming, so oftentimes they just tell people "by the way, 0 in this function is undefined"

there are no rules to say "do not do it" in real life with formulas, it will just give undefined result

but when translating it to code you need to do some extra precautions to stop division by 0

since computer is not a human who can recognize that dividing by 0 is bad and avoid it for you

[spring creek]

No, but I love things like that, i'll check it out, thanks!

[floral onyx]

So how do I take extra precautions to stop division by 0? Is there any example?

[leaden ice]

if (theDenominator != 0) {
  // do the division
  var x = theNumerator / theDenominator;
  // blahblah
}
else {
  // do something else
}```

[simple egret]

The formula paper you showed here has an issue, what if x = b in the 3rd example? Does it take the second or third case of the formula here? It's also why you can didvide by zero, the conditions should be "less than", and not "less than or equal to"

[leaden ice]

a good example is calculating averages:

int numberOfObjects = someArray.Length;
if (numberOfObjects == 0) {
  // we can't do the normal formula here since it would be dividing by zero
  average = 0; // some reasonable default?
}
else {
  float sum = 0;
  foreach (float x in someArray) {
    sum += x;
  }
  average = sum / numberOfObjects;
}```

[floral onyx]

So I should edit all the line in this https://paste.ofcode.org/3b73KHdJZVLb7ZFUdAycZGm, to decide not by "less than or equal to" but "less than" only?

[floral onyx]

Alright sir thanks

[simple egret]

It should be something like

x <  a
a <= x < b
x >= b

For the first example. So you have no ambiguity in case, say x = b, it goes in the last formula.

[floral onyx]

Ohh

So rather than this:

else if ((0.1 * maxNyawaPemain) <= nyawaPemain && nyawaPemain <= (0.4 * maxNyawaPemain))
{
// do something
}

I should do:

else if ((0.1 * maxNyawaPemain) <= nyawaPemain && nyawaPemain < (0.4 * maxNyawaPemain))
{
// do something
}

[simple egret]

Yeah that's one of the two ways. Just make sure the <= is always on the right here

[floral onyx]

Okay, I will think about it

[gray mural]

hello, do lot's of games use jwt in their games for authentication?

we have had this conversation earlier actually

[flat wing]

!learn

[tawny elk]

🧑‍🏫 Unity Learn can offer you over 750 hours of free live and on-demand learning content for all levels of experience! Make sure to check it out at https://learn.unity.com/

[gray mural]

are you reffering to me?

[flat wing]

Nop

[pure cliff]

Can you divide the items into "categories" or "strategies" that are similar in behavior?

Like SmallHealthPotion and LargeHealthPotion probably are the same thing with just the Potency or whatever parameter different right?

[pure cliff]

yeah thats pretty common for OAuth

[gray mural]

can I combine sqlite db with jwt?

[pure cliff]

different application layers, try and keep your DB layer seperate from your Authorization layer

you sound like what you want is an Asp.Net Web API, which has built in easy support for JWT authorization

[mighty yew]

maybe a little? but for the most part no. It's not a traditional invetory like minecraft or stardew, its a roguelike where every item affects a certain aspect of your playstyle, and as such has a different command to run whenever you attack or deal damage or dodge or whatever.

[pure cliff]

It sounds a lot like you can have a core PlayerStats or whatever as part of your GameState and each item modifies that, like "BootsOfQuickWalking" prolly adds a PlayerState.MovementSpeed modifier

[mighty yew]

probably something like that yeah, What i was planning on is having a parent class with functions like "onAttack" "onDodge" "onDamaged" etc, and every item overiding these functions or the players stats or something.

[pure cliff]

that sounds very difficult to maintain, I would invert that entirely

[gray mural]

don't know what it is, I just want to create normal unity online game

[mighty yew]

how so?

[pure cliff]

Your inventory items shouldnt be aware of the world outside of em, they just prolly have some kind of MutatePlayerstats function or whatever

Logic for what your Playerstats actually mean should exist in some kind of other place

Your inventory items should be "Is a" classes, not "does a" classes

Try and always seperate your classes into 2 bins:

1. "Is" something (I call these Models)
2. "Does" something (I call these Services)

Try not to overlap the two, Services can manage, CRUD, Read from, and Mutate models.

Models just sit and look pretty and hold your information, but they dont "do" things

I typically follow the paradigm that my MonoBehaviors are largely all my Models, and my Services are POCOs... mostly

[mighty yew]

While that's fair, i think you might misunderstand. almost every item will be unique and not every item just affects stats. For example, an item might spawn a gernade that drops on the floor every time the player makes a critical hit, or an item might regenerate the players health every time he dodges.

for every item i'll need a unique function that does something every time the player does something

[pure cliff]

yeah so, visually that can happen, but I would strongly encourage you to design your code so your GrenadeMakerModel doesnt actually make the grenade.

It can perhaps have the SpawnsProjectile strategy, and it can have SpawnedProjectile = GrenadeModel, and perhaps ProjectileCount = 1

But the logic of spawning the Grenade should prolly be on your ProjectileService which manages CRUD for all your Projectiles... etc etc

i have a ui rectTransform that i manually have to add to the clamped background size so that the camera moves to the edge and the player can walk to the edge of the background without blocking part of the background...when an aspect ratio is changed on a diferent monitor the background starts showing. how can i always add the size of the ui to the background so it is correct on any screen size? first image shows 1920x180, the second image is the other size 1280x720 and the ui is slightly a different size

float minX = mapMinX + camWidth;
float maxX = mapMaxX - camWidth + 5.07f;


        
float minY = mapMinY + camHeight;
float maxY = mapMaxY - camHeight;

float newX = Mathf.Clamp(targetPosition.x, minX, maxX);
float newY = Mathf.Clamp(targetPosition.y, minY, maxY);

the code clamps the camera to the background but then adds the x value of the ui manually. how can i make this work with every aspect ratio. the +5.07f is to make sure the ui is at the edge. but this number doesnt work for other sizes

[pure cliff]

is your UI on a canvas? You should be able to just get the Rect of the Canvas itself

[smoky basalt]

yes it is, i tried getting the rect of the ui element itself but its 500 width which is way too much

[pure cliff]

you can set the canvas to camera mode where you bind it to your scene's camera, and it will auto hug to the camera's viewport or whatever

[mighty yew]

I don't really know what you mean by ProjectileService, but I assume its a projectile manager for the whole game? don't really know why you would do that. I can see your point with the spawns projectile bit, that would work fine if I had a projectile manager, but that's just one of the many effects that can actually happen. If every item is going to be doing something unique, why not have unique functions for all of them? I can see how you would do something like this, but I don't really see why.

[pure cliff]

Render Mode

[pure cliff]

do you actually need unique functions for every single one.

I would put money down that chances are you absolutely can "group" them smartly into common behaviors and reduce your problem space tremendously

[smoky basalt]

that seems to work better but objects in my game are now ontop of the ui. how can i make the ui always be ontop?

[pure cliff]

by default your canvas should be on top, double check your layers and sprite rendering orders on the stuff in your UI, and same for all the other stuff in your scene that is showing up in front of the UI

[crude mortar]

I will warn that this approach has an upfront cost and can have high maintenance if your problem space changes at all throughout development.

[mighty yew]

Alright, i'll think about this and come back to you, but before that, is there an actual point to doing it your way? What's the benefit?

[pure cliff]

IIRC all UI elements you create default to being in the... I think its literally called the UI layer, which is by default the front-most rendering layer

[pure cliff]

reduce your problem space tremendously
👆

[smoky basalt]

they are all default layer and my ui is on a layer higher in the layers. do objects with sprites need to be under the ui in layers?

[pure cliff]

yeah they default are on the default layer IIRC

@mighty yew if you have like, lets say 200 unique items, but you can actually just categorize them into say, 10 unique "strategies" or "behaviors" if you will, now you have 10 functions to write instead of 200.

Im sure you can see the appeal of that ;P

[smoky basalt]

does this look right? they are still ontop of the ui

[pure cliff]

Lower = In front

the bottom in that list is the front-most, and the top layer is the backmost

[smoky basalt]

ahh okay ui is just hardcoded in unity so ill make my own ui option

[somber nacelle]

you can change the sorting layer on the canvas

[pure cliff]

you can just drag it down

or wait can you modify it

I thought you can, maybe you cant

[crude mortar]

You can't, they are editing the layer definitions

[pure cliff]

TIL

[crude mortar]

it is just a 32 bit mask for all layers, the ordering happens separately

[pure cliff]

@smoky basalt do yourself a favor and put UI layer at the very bottom XD

[pure cliff]

wait what? I thought the order mattered

in that editor

[smoky basalt]

i set the ui to pause like the pause menu but everything is still ontop

[pure cliff]

Im thinking of rendering order layers arent I

yeah thats the other layers isnt it lol

[smoky basalt]

i even moved the canvas to the bottom of hierarchy

[somber nacelle]

https://docs.unity3d.com/Manual/2DSorting.html

[pure cliff]

@smoky basalt sorry mate those layers are the physics one, for sprite rendering order stuff theres a totally seperate group of layers you gotta edit

[clever bluff]

hey Team, new to the server. Looking to post about inviting any interested Dev to join our** BlackThornProd team project: 7 Devs Build a Game WITH COMMUNICATION**.
Is there an appropriate channel where I can post it with all the details?

[pure cliff]

its in that same editor though IIRC, at the top theres uh... "Sorting Layers" Or whatever they are called

[smoky basalt]

ohh for sprites

if ui isnt a sprite its an image how do i add it to sorting layer

[somber nacelle]

#archived-code-general message

[smoky basalt]

thank you lmaooo

[pure cliff]

they really outta rename "Layers" to be like "Physics Layers" or whatever

I dunno if they get used for stuff other than that

[smoky basalt]

well now the ui isnt going to the edge of the screen..

[thorny onyx]

        var c1 = spectrum[3] + spectrum[5] + spectrum[4];
        if (c1 < 0.0002f)
        {
        //    player.GetComponent<playerMovement>().noise = false;

        }
        if (c1 > 0.0002f)
        {
            player.GetComponent<playerMovement>().canMove = true;
            Debug.Log(c1);

        }``` in this snippit, canMove is not being set to true, but the debug is showing

[smoky basalt]

this is when its 1920x1080 other ratios dont work

[somber nacelle]

#📲┃ui-ux

[smoky basalt]

im clamping the ui to add onto the background so the camera can go past, but adding the rectTransform didnt work because the image isnt a sprite

[mighty yew]

I'm honestly a little confused as to what your method is. What I understand is that theres a statsFile:

health = 3
damage = 4
void changeHealth(int x) {health +=x}
void changeDamage(int x) {health +=x}

and then every item file, for example a potion:

//InheritFromItem
overide void MutateStats(){
  statsFile.changeHealth(1);
}

Is this what you mean?

[somber nacelle]

are you sure it isn't being set to true? how can we tell from this snippet that something else isn't setting it back to false

[smoky basalt]

this was my original problem but it was almost solved with screen space- camera

[pure cliff]

sort of I suppose, theres many ways to implement it.

I would go with implementing interfaces on your items personally

[mighty yew]

Interfaces? the "changehealth" functions?

[pure cliff]

C# interfaces, which by implementing them also inherently implies what behaviors they adhere to (this lets you have items that can have more than 1 behavior too)

[mighty yew]

Alright, it's going to take me a minute to read up on those since I haven't heard of them before.

[pure cliff]

so something like

public interface IHealthBehavior {
   int HealthModifier { get; }
}
public class HealthPotion : MonoBehavior, IHealthBehavior {
    [SerializeField]
    private int healthModifer;
    public int HealthModifier => healthModifier;
}

Something like that

but then if you want to add the IThrowableBehavior to the HealthPotion, to enable it as a "throwable item" as an example:

public interface IHealthBehavior {
   int HealthModifier { get; }
}
public interface IThrowableBehavior{
   int MaxThrowDistance { get; }
}
public class HealthPotion : MonoBehavior, IHealthBehavior, IThrowableBehavior
{
    [SerializeField]
    private int healthModifer;
    public int HealthModifier => healthModifier;

    [SerializeField]
    private int maxThrowDistance ;
    public int MaxThrowDistance => maxThrowDistance ;
}

boom, now it "identifies" as both modifies health and is throwable

and you just sort of aim to break up your various "behaviors" into interfaces, and can apply any amount of em to any given item

[mighty yew]

Where is the actual "throwing" or "healing" code stored?

[pure cliff]

I would go with Strategy Pattern or maybe even Mediator Pattern, to create a Service that does the actual game state manipulation with the items

Honestly a lot of this though could be boiled down to just a Flagged enum which I think Unity can serialize? IIRC it serializes to like, a list of checkboxes?

you could then add a bunch of nullable properties for every behavior, and then your editor hides/shows the properties if you have a flag checked off or not

itll be a bit more cumbersome potentially but might be easier to work with in the consumer

[mighty yew]

I'm not really sure what either of those are sorry.

[latent latch]

What would be the benefit of this over a general inheritance approach and virtualization. I probably don't take advantage of interfaces that much beyond using them for type identity when using generics and stuff.

[pure cliff]

you cant inherit from multiple classes

you can, however, implement multiple interfaces

[latent latch]

Right, but say, Item -> HealthPotion

Actually, ok yeah I can see the usage of interfaces this way

Rather, it would probably make more sense to do some inheritence here, and tack on the throwable interface on the inherited class

[pure cliff]

Flagged Enum is also totally valid, but you'll wanna do some fancy work with the enabling show/hide of your various fields based on enum values selected

[jaunty sleet]

Has anyone ever had issues serializing an object with a Dictionary as a property using Newtonsoft Json Utility? I have an object with a Dictionary property that I know has items in it, but when I save it in a json file it is empty. I have no clue why 😭

[pure cliff]

yeah if you want all health potions to be throwable, you implement throwable behavior on say, HealthPotionBase

If you want them not throwable by default and then you make a special ThrowableHealthPotion, you put the interface on that child class

[latent latch]

Man, I really want to dive into ECS but too committed to my projects

[pure cliff]

I gotta jet in a sec, I got a technical interview for a new job but feel free to ping me with questions still, but prolly wont be back for an hour

[mighty yew]

It's alright, i'll try to make some sort of sense of this

[pure cliff]

god I hope its not just a bunch of "re-write quicksort from scratch, now write code to invert a binary tree" type of stuff, nngh

[jaunty sleet]

Do you know anything about the json dictionary thing before u go

[mighty yew]

im not really sure on the enum thing, and i'm almost certain that it would make this several times harder, but the interfaces are actually pretty helpful

[pure cliff]

Its a common issue IIRC, I believe that one should get results from googling

[jaunty sleet]

I have been trying but I haven't found the reason

[mighty yew]

im imagining I can have an item interface that every item inherits from, and then a "healthchange" or a "on-hit" interface that only certain items inherit from

[pure cliff]

interfaces mostly will involve you wanting to do some if (item is IThrowable throwable) .... casting "is a" checks

enums will maintain type safety and wont need casting, but your objects will all have a whole buncha null properties on em

[mighty yew]

and then I can just have a list of items? im hoping I understand this

[pure cliff]

you dont inherit from interfaces, they are more like a contractual obligation your class says it will adhere to.

You "implement" an interface, and "inherit" from a class

basically when you go

MyClass : IMyInterface

You are committing to MyClass implementing whatever IMyInterface said it has to implement

like a contract MyClass has signed and promised to adhere to, and if it doesnt, it throws a compile time exception and wont compile, and says "Yo, you said you'd do this thing but you didnt"

[mighty yew]

Ok, that makes sense

[latent latch]

An example of an interface I use is one I call IEntity, such that any script that implements it will be guaranteed to have a Stats object, an Ability class object, and an Equipment class object. This is helpful in unity because instead of checking for specific components of a gameobject, I can simply check if it includes this interface, making operations easier when doing sphere casts and such. Additionally, instead of exposing a script completely, this reference will only allow you to access what the interface implements.

[fervent jacinth]

how can i check if theres an object in this cone?

or put planes along the sides

[floral onyx]

@leaden ice @crude mortar @simple egret Sir, I found it, there's no more NaN, turned out the problem is in the last stage, it's 0:0. So I use this way to decide the output. I put "0" as defuzzy in else {}.

[latent latch]

You'd need to use some casting method, probably want to avoid raycasting directly. Some combination of spherecast/boxcasting with distance calculations is what you'll probably want to look into.

[fervent jacinth]

im using ezy slice, so i want to put planes along the sides and cut the things intersecting with the camera border

basically clearing the mesh in front of the cam

[trim ferry]

guys im having a problem here, i made a Player movement system, it works perfectly, but when i restart unity, the vision only moves in the X axis.. Here's the script btw: https://hatebin.com/rprqcbrcih

and if i dupllicate the player and delete the original one, it goes back to normal.

[latent latch]

https://www.youtube.com/watch?v=XrqesjfcitU
Zero actually has the idea about locating what's in vision of the camera, but even with that information, you'll have to figure out the bounds relative to the camera of the object you want to trim.

[fervent jacinth]

im trying to create something like this, so i dont know if thats what i need https://www.youtube.com/watch?v=8rr83zwzlOA&t=1s

[wooden cove]

is there a simple way I can get an x, y output from a bool[,] depending on whether or not a certain element is true or false? I wanna get the indices in the array that are true

preferably without a for loop

[leaden ice]

you will need a loop

but a better option may be to just use a HashSet<Vector2Int> in the first place, rather than a bool[,]

[wooden cove]

on the left, you can see a bool[4,4] and on the right a bool[3,3].
I want to check if the current location of the 3x3 is valid in the 4x4
(providing the full context for my question)

using a hashset would leave me without the data I need to verify if a field is taken

assuming I can make a class that holds a Vector2Int and bool and make a HashSet out of that is a better option, would that be the middle ground im looking for?

[leaden ice]

no it would not

HashSet<Vector2Int> whiteSpaces = new() // or blackSpaces?? IDK which is which
bool IsTaken(Vector2Int space) {
  return whiteSpaces.Contains(space);
}```

the HashSet<Vector2Int> gets you everything you have now PLUS an extremely easy list of "taken" spaces (just iterate over the set)

[wooden cove]

ah I see, it would make more sense to me to invert the whole thing since I only need to know the open spaces tho. but th e logic is sound

keeping all positions in a hashset, and removing them when the spot gets filled @leaden ice

[leaden ice]

yeah that works

[wooden cove]

are HashSets serializable to the editor?

[leaden ice]

not directly

you will have to serialize it as a list

and read it into the HashSet in Awake

[wooden cove]

in that case I might keep the 2D array for the initializing data and convert to a hashset to manipulate

[leaden ice]

yeah

or that

but 2D arrays aren't serializable either

only 1D arrays

you could use an array of Vector2Ints, or a list of them

[wooden cove]

I should note that I am using Odin Inspector, so a lot of the serialization limitations are not applicable here

[leaden ice]

oh

ok

if you're using Odin

then HashSet probably works directly

try it

[wooden cove]

I was also just thinking that

[lucid wigeon]

Do you use assertions (Assert.IsTrue()) in code or rather exceptions for cases which should not happen like "Trying to add vehicle to inventory" (what should be already disallowed somewhere else)?
Assertion seem to be convenient to spot invalid states or bugs in the code but after they are removed in build the game might end up in some weird state if that condition is met somehow...

[wooden cove]

https://odininspector.com/documentation/sirenix.serialization.hashsetformatter-1 if it isnt, it seems easy enough to implement

[leaden ice]

If that exists then it seems like it should work out of the box

[wooden cove]

altho im quite certain it will be serialized to JSON by default

same as with dictionaries

[leaden ice]

Odin is a thing that I own that I always forget about 😆

[wooden cove]

haha

we use the serializer and validator for our projects

validator is quite a powerful tool we have in the pipeline

serializer is nice, but most of the inspector stuff it provides can be done manually without relying on it.
It does really speed up my tool production tho

[smoky basalt]

does anyone know how to calculate the size of a ui element in the canvas. it says the width is 846.2356 but i need the actual sprite size which is 5.07f how is this conversion done?

[leaden ice]

what do you mean by "actual sprite size"?

[smoky basalt]

i know rectTransform is different from transform

i just dont know how to get the transform size of a rectTransform

[leaden ice]

what does "transform size" mean in your mind?

[smoky basalt]

this is 14.13 if its a rectTransform its based on width

[leaden ice]

that's a position

but

It's more complicated than you're thinking.
The coordinates of the RectTransform are in Canvas space, not world space. And the conversion between canvas space and world space depends on the canvas render mode

as well as the canvas scaler

so - maybe you could explain exactly what you're trying to accomplish here?

[wooden cove]

I was about to ask for clarification as well, its a bit unclear

[smoky basalt]

if you would please look in #📲┃ui-ux you would see my issue. im trying to clamp the camera to the background but the canvas overlays. i want to add the canvas to the x so that the clamp also shows the background+ the canvas

[pure cliff]

Write unit tests!

[steep scarab]

hey guys sorry for double question but I posted this in #💻┃code-beginner before a huge code block and it kinda got skipped, but I just need to know how would I go about getting the horizontal FOV of my camera in degrees? camera.FieldOfView returns the vertical fov in degrees, which as can be seen here works fine for moving the center of my vignette, however I need to find a separate value for the horizontal FOV for the scope thingy I'm doing so it scales correctly horizontally

[leaden ice]

probably this?
float horizontalFov = cam.aspect * cam.fieldOfView;

[vagrant oyster]

There's also a function in Camera

https://docs.unity3d.com/ScriptReference/Camera.VerticalToHorizontalFieldOfView.html

But they should work the same

Correction: The formula is far more complicated (https://en.m.wikipedia.org/wiki/Field_of_view_in_video_games#Field_of_view_calculations), and you should use the Unity function.

[steep scarab]

thanks man I'll try it!

[leaden ice]

Oh I would 100% absolutely use this @steep scarab

the formula might not be as simple as I said

it was just my first instinct

[steep scarab]

ah ok thanks man appreciate it!

[steep scarab]

this ended up being close enough if not just a tiny bit off. the function seemed to be having compile errors but I'm sure I can figure it out later

[somber nacelle]

that's a static method not an instance method

[steep scarab]

I need to take my ass back to #💻┃code-beginner

[somber nacelle]

call it directly on the class, not on an object reference. it's just Camera.HorizontalToVerticalFieldOfView(<parameters>)

[steep scarab]

oh my goodness I'm so dumb 💀

thanks lol

[somber nacelle]

also your local variable is misleadingly named, it should be verticalFov not horizontalFov since that method returns a vertical fov

ah wait, you're just using the wrong method actually. you want the VerticalToHorizontal one since mainCam.fieldOfView is the vertical fov

[steep scarab]

yeah lmao 😭

appreciate it tho man thanks I feel dumb asl now tho lol

[shadow hedge]

any help plz?
#💻┃code-beginner message

[jaunty sleet]

Hey @somber nacelle, do you know why an objects properties that have values would be empty upon the object being serialized into a json file? This problem is actually driving me insane

No matter what I do there are no values in the json file even though there are values there before it is converted

[somber nacelle]

don't ping people into your questions

[jaunty sleet]

ok

[lean sail]

Why: because a lot of reasons. Show your actual code so people can help

[jaunty sleet]

https://paste.ofcode.org/FMRQpxSwGr8XJxjff39FZk

It's kind of ugly rn because I have been trying a bunch of things to fix it. But the problem hasn't changed at all

The methods in this file are also called by my game manager script, but I have printed out the values to confirm that they are there, and it really isn't empty

[hidden parrot]

first guess, i dont think newtonsoft serializes auto properties

[somber nacelle]

this won't fix your issue, but lines 39 through 47 can be reduced to just

string[] enemyIDs = enemyStates.Keys.ToArray();
bool[] enemyStatuses = enemyStates.Values.ToArray();

[lean sail]

How come you are using json utility when you have Newtonsoft? Havent used json utility specifically but I dont think it can store that

[hidden parrot]

hes not

[jaunty sleet]

I was using newtonsoft, I tried json utility to see if it would work and it didnt either

[hidden parrot]

jsonconvert is the newtonsoft one

jsonutility is base

[somber nacelle]

they are serializing with JsonUtility though

[lean sail]

He is

[hidden parrot]

Ah.

[jaunty sleet]

That is good, if only I could get the other thing to work lol

[somber nacelle]

try with fields instead of properties

[jaunty sleet]

I have tried that. Aren't properties supposed to be serializable?

[somber nacelle]

not with JsonUtility 😉

[jaunty sleet]

I was using newtonsoft before and it didnt work

[hidden parrot]

nah, make backing fields with serializefield i reckon

[jaunty sleet]

I am just going to put it back to newtonsoft as well bc jsonutility isnt helping

I would make backing fields as a work around if having fields worked

Changed to fields and newtonsoft, this is the output in the file: {"EnemyIDs":[],"EnemyStatuses":[]}

Originally I wasn't converting my data into arrays and just leaving it in a dictionary, which is supposed to be supported by newtonsoft. I only chaanged it to this because it wasn't working

I am just completely lost here

Ok I think I figured it out. The method is being called twice which somehow results in the output being empty. Idk how that is happening though

[smoky basalt]

Hello im using rigidbody moveposition to move my enemy toward the player but for some reason they start slowing down as they reach the player. is there a way to keep the speed. i think they are faster the further away they are from the player as well which i dont like

            Vector3 dir = (player.position - rb.transform.position).normalized;
            //Check if we need to follow object then do so 
            if (Vector3.Distance(player.position, rb.transform.position) > minDistance) {
                rb.MovePosition(rb.transform.position + dir * speed * Time.fixedDeltaTime);
            }

[jaunty sleet]

Does anyone know why the buttons from this script are double triggering? I have no idea why this happens. ```using UnityEngine;
using UnityEditor;
using System;

public class TestingMenu : EditorWindow
{
public static Action saveEnemyState, loadEnemyState, addEnemy;

public static string EnemyID { get; private set; }
public static bool EnemyState { get; private set; }


[MenuItem("Window/Testing Menu")]
public static void showWindow()
{
    GetWindow<TestingMenu>("Testing Menu");
}

void OnGUI()
{
    GUILayout.BeginHorizontal();
    if (GUILayout.Button("Save Enemy States")) saveEnemyState();
    if (GUILayout.Button("Load Enemy States")) loadEnemyState();
    GUILayout.EndHorizontal();
    GUILayout.BeginHorizontal();
    if (GUILayout.Button("Add Enemy")) addEnemy();
    EnemyID = EditorGUILayout.TextField("Enemy ID:", EnemyID);
    EnemyState = EditorGUILayout.Toggle("Enemy Is Alive:", EnemyState);
    GUILayout.EndHorizontal();
}

} ```

This is the cause of my problem from earlier

[somber nacelle]

unless you are changing the value of speed or you've removed some code between the first line and the if statement then your movement speed isn't any slower. however if you only move it when the distance is greater than your "minDistance" but the player keeps moving even when this object reaches that minDistance it may appear to start and stop over and over

[smoky basalt]

it is in fixed update should i move to update so it calculates better?

[somber nacelle]

no

[smoky basalt]

awesome ill just try using addforce and see if that works better

[jaunty sleet]

Does anyone know if GUI layout buttons in Unity editor windows normally double trigger when clicked? Or am I doing something wrong here?

[lucid wigeon]

Lol, my brain is dead. Instantiating a plain class with [Serializable] should work like that or not? I cannot comprehend how is that possible: values chunkWidth and chunkHeight are serialized properly with 50. In debugger they are set to 50. But my array inside this object is instantiated using other values (12,10,12). But I create this array in the constructor. And the values which are used for this are serialized properly. I cannot comprehend this. When I call this ResetCubes() from outside script in Start() method then it works.

[somber nacelle]

unity cannot serialize multidimensional arrays

[jaunty sleet]

To serialize multimensional arrays, you can make a struct with an array as a field

make the struct system.serializable

then make an array of the struct

That will allow you to have a multidimensional array in the editor window

[lucid wigeon]

no, i don't want to serialize it, I'm creating a new one in the constructor

[lucid wigeon]

I can remove [SerializeField] for private Block[,,] cubeMap; because that doesn't work at all, you are right it is not serialized

[jaunty sleet]

You should upload the code, it would be easier to understand then screenshots

[lucid wigeon]

Right

[somber nacelle]

but you are not calling the constructor. your model field is serialized which means unity will assign the serialized instance. which of course means no multidimensional array because that cannot be serialized 😉

[lucid wigeon]

so serialized classes don't have their constructor called?

[somber nacelle]

why don't you do some debugging and find out

[jaunty sleet]

also boxfriend have you ever had an issue with GUILayout buttons triggering twice?

[somber nacelle]

i don't use it so i don't have info about it. if i knew the answer to your question i would have already provided it

[jaunty sleet]

Ok, thanks

That's so weird that it does that. So now I have to go set up some stupid boolean thing to make it not trigger the second time? It doesn't make sense lol

[lucid wigeon]

looks like the constructor is called

[jaunty sleet]

Yeah, I don't see why it being serialized would prevent the constructor from being called when using the new keyword

[somber nacelle]

did you remove the field initializer that creates an instance of the Chunk class to ensure that unity's deserialization is actually calling the constructor?

[leaden ice]

the constructor runs before the serialized values are copied over

so your width/height etc will not be set when the constructior runs

you can't really rely on the constructor in the context of serialization in Unity

[lucid wigeon]

ok, I suppose that's the problem

I suppose the instance is first created and then public vars are set by the serializer

I have assumed that the public vars will be already set to inspector values when the object is instantiated

[somber nacelle]

this is why using the debugger is important. so you can see what exactly is happening and when

[lucid wigeon]

so I suppose it's not worth doing anything meaningful in the constructor if using plain classes because that's bug prone

[somber nacelle]

don't do anything that relies on any of the serialized values in the constructor

[lucid wigeon]

ok, thanks for help

[sharp sky]

Quick question. A while ago I had been using visual studios and it had given me some useful help in coding. For example I would be typing "public Vect" and it would predict and give different options that I can finish it with such as "Vector3" and all these would be a light green/blue color. However, now my new version does not do that at all nor does it have the lettering green/blue making it blend in with a lot of other code. Is there an option somewhere to turn that on again?

im in one helluva delema. I want to make a progressive shotgun reload (reload shell by shell over time until full, but can be fired at anytime during reloading as long as there is one shell in the gun) I use a coroutine to time the reloads then call a function to manage the change in ammo and call the corutine again to prepare the next reload. I am indecisive on how to cancel out of reloading, do I just clear the coroutine and prevent reloading with a change in boolean?

[spring creek]

You could. Like have the "continueReloading" bool which is checked before reloading another round, and if the player tries to fire it is set to false and they fire when the current reload completes

[lean sail]

it really wouldnt matter much which one u choose, regardless the reloading is either gonna swap the value of the bool or start another coroutine to continue reloading. Id probably go with stopping the coroutine

[topaz sapphire]

ok thanks

[topaz sapphire]

both of you

Hi, im making a script to read text from a txt inside the resources folder. I just read that using resources folders is not recommended so Im asking if this is true

[leaden ice]

It certainly has drawbacks.

Basically everything in Resources will be loaded into memory immediately when the game starts

So it's bad for memory usage if you only need the data sometimes

[vocal root]

well i need the text to put it inside a list at the start so its just once

[leaden ice]

It stays in memory

Any reason you can't just drag and drop it into your list?

As a TextAsset

[vocal root]

I want to have a txt to add more words in time

and if i change something in the script the list just clear itself so i dont want to write that much

i mean if i change the name of the list and that kind of things

[ocean oasis]

I gotta reask this because I don't think anyone ever had any ideas on it, but I used this tutorial to make soft body objects; it worked perfectly:
https://www.youtube.com/watch?v=W3x143cYF88&start=197
But then I made a simple script to scale the localscale with time, and while growing, the objects' spring joint completely just let go and the thing collapses, while growing. It become's a rigid soft body again once it's done growing.

[wicked wagon]

Is there a difference between these?

  private void Update()
  {
      currentZoomState = inputManager.Zoom;
  }```
  ```private void Update()
  {
      bool currentZoomState = inputManager.Zoom;
  }```

[ocean oasis]

Yes, in the update function, there is a brand new variable being created each frame

in the first one, there is a single variable that is created, and then updated each frame

[somber nacelle]

yes, the first is a field whose scope is the entire class. the second is a local variable that can only be accessed within the Update method

[ocean oasis]

in the second one, the variable is deleted at the end of each frame and recreated

[somber nacelle]

i recommend looking up variable scope to understand how it works

[ocean oasis]

^^^

[leaden ice]

The second variable can only be used inside Update too

[pure cliff]

You can setup a script to run during edit time and auto populate your list, so its all preloaded at compile time

[wicked wagon]

alright guys thank you all

[topaz sapphire]

after messing arond with calls that prevented it from working correctly, shotgun reloads as intended

[pure cliff]

Can even do a custom importer for a type of file extension you specify for your text file, and then it imports it instead as your actual output object type you need it to end up as

[vocal root]

no way to dump a txt file into a list without reading it on resources then?

[pure cliff]

As I just said above, you can instead make it an asset and change file extension

And use custom importer to convert it to your actual object you need it to be

Thus you "preload" all that work and compile it in, so you aren't doing all that work on boot up

[slate trellis]

I have this code right here:

if (Physics.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition)/* start position */, Vector3.down /* direction */, out RaycastHit hitInfo /* hit location info */, maxDistance, layerMask))
        {
            transform.LookAt(hitInfo.point);
        }```
I have a sprite in a 3D world view and I want it to rotate to where my cursor is. I have tried countless methods found on forums, video tutorials and a suggestion by a partner of mine. nothing works. I cam up with this solution, but I found out about a bug(?).
`Camera.main.ScreenToWorldPoint(Input.mousePosition)` this returns a static value relative to the player's position and not where the mouse is. I tried applying it to different GameObjects, even an independent one, but this seems to be a reocurring issue. I am requesting for a solution to my problems.

verison is 2022.3.5f1 LTS

[slate trellis]

I can't seem to understand the point made

[quartz folio]

Input.mousePosition is (x, y, 0) which will always return the camera position

If you want to cast a ray out of the screen where the mouse is, use

Ray ray = camera.ScreenPointToRay(Input.mousePosition);
if (Physics.Raycast(ray, out RaycastHit hit))```

[vocal root]

sorry to bother again but the folder StreamingAssets have any disadvantage like Resources?

[slate trellis]

I made the code, but it seems to rotate the X and Y axis, but I want to rotate only the Y axis. how would I do that?

found the solution, thanks!

[opal bluff]

I have an issue, when i push S to turn the bool "isPogoing" on the input becomes true, and it triggers fine, but if i hold down S the bool stays true for a while an doesn't switch off even if i let go of the key, i've fixed the problem by removing verticalinput which gets the y axis, but i need it for controller support so im confused how to fix it, heres my code if (Input.GetKey(KeyCode.S)||verticalInput<0) { isPogoing = true; isAttacking = false; } else { isPogoing = false; isAttacking = true; }

[topaz sapphire]

it the one in the manual, is there a better one?

[somber nacelle]

are you using an ancient version of unity?

[topaz sapphire]

2021.2

[quartz folio]

Then it's not "the one in the manual"

it probably also tells you what to use if you hover over it, it's gotta be underlined for a reason

[topaz sapphire]

done

so how can I

[opal bluff]

its still delaying when the bool is false

like if i hold down the bool for too long it stays true for a long time

[cosmic rain]

Share the updated code.

[opal bluff]

        {
            isPogoing = true;
            isAttacking = false;
        }
        else
        {
            isPogoing = false;
            isAttacking = true;
        }

        if (verticalInput < 0)
        {
            isPogoing = true;
            isAttacking = false;
        }
        else
        {
            isPogoing = false;
            isAttacking = true;
        }```

[cosmic rain]

That's not what I suggested.

You still need to check wether the controller is used or not.

[opal bluff]

vertical input calls the y axis which basically uses the controller input tho?

is there another way?

[cosmic rain]

But you don't want that if statement to be evaluated when the controller is not used, do you?

[opal bluff]

no i mean like I dont want the bool to be true when the button isnt being pressed like immediately, my problem is everytime i press the button for a little too long it stays true even if i let go, i want it to immedately become false when the player lets go, if i only have the button be S its fine, but for some reason verticalInput is making it true for longer even if i let go of the buttton, i want the isPogoing bool to be false as soon as the player lets go of the button

[cosmic rain]

Well, that just means that your vertical input is being < 0 for a longer time.

[somber nacelle]

have you considered that your numbers being passed to Random.Range may be too large?

[opal bluff]

yea i dont know why tho

[cosmic rain]

Well, where do you set it? Debug it properly.

[opal bluff]

verticalInput = Input.GetAxis("Vertical"); i put it in the update function and the code above is in update as well

but thats how im calling the verticalinput

[topaz sapphire]

the values are literally 1 and negative 1

that cant be too large can it

[somber nacelle]

is that what they show they are in the inspector?

[cosmic rain]

Try GetAxisRaw instead.

[somber nacelle]

in that case i don't see why you need the three Random.Range calls when you could just use Random.insideUnitCircle and set z to 0 (unless you want it to potentially shoot backwards, in which case keep your z as it is i guess)

[topaz sapphire]

yeah the values just needed to be tightend im actually just a moron

[opal bluff]

oh my gosh okay ty getaxis smooths it from 0 to 1 while getaxisraw returns it exactly

[cosmic rain]

Yes

[peak musk]

might be worth it to just use getkeyup

[opal bluff]

hm how come

its snapping it on and off i had getkeydown and getkeyup before but it just seemed like too much writing

[peak musk]

Just seems like a good trouble shooting step. you're already writing all the code out twice, it shouldn't be much less efficient to ask the program to check for GetKeyUp instead of a blanket Else, which has been finnicky for me in the past

[opal bluff]

ah okay thats a good point

[pure cliff]

So I am having a strange problem where my .editorconfig file is simultaneously being detected by Visual Studio and Rider, and yet not actually being applied to my code editor, and its very annoying because its causing my personal code style to just... be ignored on unity projects, so lots of stuff gets highlighted as a problem that I dont want highlighted.

Anyone had this before?

Its error'ing it as missing braces, but preferences clearly have loaded that to be not an error

[hidden gulch]

ok so i want to make interactables in my game
basically click: call a function in a script
thing is: i need the script name to be able to call functions in it, but the script names will be different bc the scripts are different and need different names for better identifying.
my solution to this was to get all scripts in the object(the object will only have the interact script in that case) and get the 1st script and call the function in it, but i have no idea how to do that. tell me if this is an xy problem and if there is a better sollution

this is my current code:

public class InteractTest : MonoBehaviour
{
    public bool open;
    
    public void SetState(bool newState)
    {
        open = newState;
    }
}

public class PlayerInteract : MonoBehaviour
{
    private PlayerInventory PI;
    public const float intRange = 4f;
    void Start()
    {
        PI = GetComponent<PlayerInventory>();
    }
    void Update()
    {
        if(Input.GetMouseButtonDown(0))AttemptInteract();
    }
    void AttemptInteract()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit rayHit;
        if(Physics.Raycast(ray, out rayHit, intRange, LayerMask.GetMask("Interactable")))
        {
            GameObject other = rayHit.collider.gameObject;
            GameObject curItem = PI.HeldItem;
        }

    }
}

[leaden ice]

You can just use the EventTrigger component

and hook up the PointerClick event to your various script functions

(just make sure your camera has a PhysicsRaycaster on it, and your scene has an EventSystem in it)

[hidden gulch]

alr, ill try looking further into that

by eventsystem you mean something like this right?(i have absolutely no idea how this got into my scene but its here)

[leaden ice]

yes that

it gets added automatically whenever you add any UI element to the scene

you can also add one manually by GameObject -> UI -> EventSystem

[hidden gulch]

oh makes sense, i was trying to do some pixelization with a renderimage

[leaden ice]

don't worry it's for non-ui stuff too with the approach I described above

[hidden gulch]

is the standalone input module also nescessary?

[leaden ice]

yes

[hidden gulch]

alr

[hidden gulch]

wait is the standalone input module the new input system

[leaden ice]

no

it's the input module for the old input system

there's a different input module for the new input system

[hidden gulch]

oh alr

bc when i searched for the standalone input module i only found videos on the new input system

[pure cliff]

thing is: i need the script name to be able to call functions in it, but the script names will be different bc the scripts are different and need different names for better identifying.
A lot of what you just wrote there doesnt really mean anything in the context of C#. Id recommend getting more familiar with the lexicon of C# so you can better convey what you mean here.

"script name" isnt a thing in C#, Im not sure what you mean by "script name"

[hidden gulch]

file name

[pure cliff]

or at least typically "script name" would just be the file name

[pure cliff]

you shouldnt care about file names like that, you deal with "classes" in C#, which are declared in your files

[hidden gulch]

ok so to declare a variable to store a "script"(FileName VarName = new FileName;) i can just use the name of the class?

as filename

wait lemme reformulate the question

[pure cliff]

largely speaking... you shouldnt really be even discussing handling file names at all in this context

[hidden gulch]

is FileName VarName = new FileName; correct or is ClassName VarName = new ClassName; correct

[pure cliff]

the second one 🙂

[hidden gulch]

alr, thank you

[pure cliff]

pretty much always you keep your FileName.cs to be the same as the class you declare inside of it

and, furthermore, theres stuff other than classes in C# you can declare, like enums and interfaces

[hidden gulch]

but in that case id have to keep my different interact scripts in different folders right? bc the class name would just be "Interact"

[pure cliff]

Its typically a good idea to keep the names distinct so you dont mix them up

otherwise you will have a bunch of "Interact.cs" files in your tabs in your IDE and, how would you know which is which?

[hidden gulch]

yea thats what im trying to say, but then i wouldnt have a fixed name for the class inside of it.

wait can i just have a filename class and a interact class

and just leave the filename class empty?

[pure cliff]

lets start from the top

whats your actual goal, high level result in like, video game terms from someone playing your game

[hidden gulch]

alr

[hidden gulch]

i want someone to click and interact with something theyre pointing at that is in the interactable layer

[pure cliff]

sounds good so far

whats the technical challenge you forsee, without talking about code yet but like, describing the problem in plain english

imagine you are trying to describe the problem to someone who doesnt know anything about C# yet

[cosmic rain]

File and class names are decided at compile time. I don't understand what you mean by them not having "fixed name"?

[hidden gulch]

can i draw a board and send it here

not beeing ironic or sarcastic, just makes it easier to explain

[pure cliff]

Im sure I will understand but, just give it a shot first at describing the technical challenge

[cosmic rain]

Ok, that's easy. Just cast a ray at the scene, get a component that you want to interact with, and interact with it.

[pure cliff]

"I want to do x, but the challenge is y" etc etc

(I already have a pretty good guess as to your issue because its a very common one that gets asked in here multiple times per day, but its good to get into the zone/habit of articulating challenges this way)

[hidden gulch]

alr, i need to send a ray from the camera in the direction that the camera is facing, if that ray hits something that is in the "interactable" layer it will get the interact script inside it and execute its "Interact()" function. but to get the interact script inside it i need the file name of the interact script(because you need to specify the variable(that stores the script so you can call its functions) type), but if i name all files the same(so i always know the file name), ill get a bunch of "InteractScript.cs"'s in my editor and i dont want that, also i'd have to separate the files in different folders bc there cant be two same named files in the same folder.

[pure cliff]

but to get the interact script inside it i need the file name of the interact script
You typically use GetComponent<T>() where T is a Type, not a filename

[hidden gulch]

so i only need the name of the class(the class is a type)

[pure cliff]

The handy thing here is GetComponent works with Polymorphism and Encapsulation

[hidden gulch]

whats that

[pure cliff]

something very important to read up on when it comes to C# and all forms of OOP

[hidden gulch]

alr ig ill check it out

[hidden gulch]

ok so basically polymorphism means it can get a component by it's parent class(classes like Collider, MonoBehaviour, etc.) right?

[pure cliff]

but the long and short of it is, lets say you have:

abstract class FruitEntity : MonoBehavior { ... }

and then you implement some classes that inherit from it:

class AppleEntity : FruitEntity  { ... }
class BananaEntity : FruitEntity { ... }

If you put an Apple component on Object A, and Banana component on Object B, but if you use

otherObject.GetComponent<FruitEntity>();

It will work for both the Apple and Banana components, because they both are FruityEntitys

[pure cliff]

exactly yup

[hidden gulch]

and now i realised i could be using class parenting to solve this issue

[cosmic rain]

It's called inheritance

[hidden gulch]

so i need to create a parent class(lets call it interact) that will have basic interacting functions and subclasses that inherit from that class and those will be singular to objects

[hidden gulch]

ok

[spring creek]

But you can't access the child variables or methods through getting it that way, unless they override the same methods. Just as something to be aware of

[pure cliff]

Thats one approach, but there also can be even easier ways to consider

[hidden gulch]

yea thats what i was thinking

[hidden gulch]

like what?

[pure cliff]

The next thing to consider:

All of these objects, do they have common functionality? You can have many instances of the same class, but they behave differently simply by modifying properties/fields on them. The code can be the same, but just changing configuration of them changes how they act

Which means just 1 single file and then you make prefabs with that 1 component applied, and you just modify parameters on it to change its behavior

[cosmic rain]

You typically don't want to be dependent on specific behaviour of sub classes. You should be able to achieve specific behaviour by calling the base class methods/properties.

[hidden gulch]

no im making wildly different mechanics like cutscene interactables to doors, but i can also just make a "type" variable on the interact script and that'll change the functionality

[hidden gulch]

why tho? just good practice or performance issues?

[pure cliff]

thats valid, but perhaps you can still very much "categorize" them into a couple specific "types" or "behaviors"

[spring creek]

To get the most out of it

[pure cliff]

like you may perhaps have hundreds of interactables... but you can group em up into a small handful of types of interactables

[cosmic rain]

Good code structure. You want your code to be readable, extendable, debuggable.

Hardcoding complex systems makes them hard to maintain.

[hidden gulch]

you mean using the same script for two interactables that have the same functionality?

[hidden gulch]

makes sense

[pure cliff]

yeah like all pickups likely can have the same code with just params for what gets added to your inventory

and all your NPCs also likely can just use a single "NPC Interactable" class, and you just customize some properties on that to define the behavior, what they say, etc

[hidden gulch]

makes sense, although im not handling pickups as interactables.

alr, tysm for the help

ill go finish my code now

[pure cliff]

fair enough, point being is to start by thinking about if you can simplify your problem space down to be a lot smaller and easier to work with

[hidden gulch]

alr

i shouldve have thought of this solution earlier tho, as i was trying to identify all the colliders in an object by using GetComponent<Collider>(); which is basically the same thought process

also i couldve just used GetComponent<MonoBehaviour>() if i was trying to do 1st solution i suggested, but idk if the transform or other components are inheriting from monobehaviour as its a common class so its probably not a good idea to do that

[pure cliff]

Now in other news, Im trying to sit here and reason out a bit of a puzzle, and Im sort of unsure how to proceed.

I have a 8 way movement topdown tile turn based game where theres a few ways the player can interact with picking their next action to perform.

By default its just moving, and I highlight an A* path to where their mouse is hovering to show where the character will go if they click, if its a valid tile they can get to. Otherwise, no highlighting.

I also have the ability to click abilities with cooldowns, which will switch to instead highlighting "valid" tiles they can click to use the ability on (IE, they can use roll which rolls em 2 tiles in a direction they choose, or shoot a bow in 1 of 8 directions, etc etc)

So once ability is selected, its icon swaps to a cancel button to swap back to the default move mode.

And, while in ability mode if they hover over a valid tile it turns green of course.

I am trying to figure out a clean approach to sort of handling all these possibilities in 1 nice flow of logic for what tiles are highlighted vs not, and whether to swap to "okay stuff is happening now"

I have 2 methods on my UIService that already facilitate drawing tiles:

1. void ClearHighlights()
2. void RedrawHighlights(Vector2Int origin, (Vector2Int Offset, HighlightColor Color)[] tiles)

So that part is solved, the second method draws the array of tiles with respect to the origin passed in as the first param

[cobalt elm]

I am participating in sebastian lagues chess challenge, I am trying to implement move ordering with no success. The times for each move increase drastically when I have move ordering enabled.

Now in other news Im trying to sit here

[slate trellis]

I am having a problem with cameras. I want to use the player to get in a car and then disable the player, resulting in the camera having to change angles from the player to the car. It throws me this error NullReferenceException: Object reference not set to an instance of an object. I have assigned all the correct values and objects in their referring scripts but it keeps showing it.
Here is the relevant code for the camera:

public void CurrentCameraLocation(CameraLocation newLocation)
    {
        if (newLocation == CameraLocation.Player)
        {
            player.SetActive(true);
            transform.position = new Vector3(cameraPosPlayer.position.x, cameraPosPlayer.position.y, cameraPosPlayer.position.z); 
        }   
        else if (newLocation == CameraLocation.Car)  
        {
            player.SetActive(false);
            transform.position = new Vector3 (cameraPosCar.position.x, cameraPosCar.position.y, cameraPosCar.position.z);
        }

        cameraLocation = newLocation;
    }```
Here is the relevant code for the car:
```cs
void Update()
    {
        if (rotate)
        {
            rb.freezeRotation = false;
        }
        else
        {
            rb.freezeRotation = true;
            transform.position = startPosition;
        }
    }```
and here is the relevant code for the player:
```cs
void OnCollisionStay(Collision collision)
    {
        if (collision.collider.gameObject.TryGetComponent<GetInCar>(out GetInCar getInCar) && Input.GetKeyDown(KeyCode.E))
        {
            cameraScript.cameraPosCar = getInCar.cameraPos;
            getInCar.rotate = true;
            changeToCar = true;       
        }
    }```

[buoyant crane]

You should send it to the community discord doing the challenge(last link in the readme): https://github.com/SebLague/Chess-Challenge#faq-and-troubleshooting

Actually it looks like you already are in the server

You can go send the code there

[buoyant crane]

Which line is it throwing the null reference exception for?

[slate trellis]

void OnCollisionStay(Collision collision)
    {
        if (collision.collider.gameObject.TryGetComponent<GetInCar>(out GetInCar getInCar) && Input.GetKeyDown(KeyCode.E))
        {
//38        cameraScript.cameraPosCar = getInCar.cameraPos; // this line here
            getInCar.rotate = true;
            changeToCar = true;       
        }
    }```

[cobalt elm]

I’ve asked for help multiple times there and have gotten no reply.

I’ve also asked for working code to analyze

Haven’t gotten any

I’ve looked at Sebastian’s himself and still can’t find what I’m doing wrong 😭

[spring creek]

Which line is the error on though

[slate trellis]

I highlighted it with a comment

line 38

[buoyant crane]

cameraScript is null then

[slate trellis]

What would you suggest to fix it?

[spring creek]

What gameobject is cameraScript attached to?

[cobalt elm]

actually getting some help right now @buoyant crane thx tho

[slate trellis]

camera holder

it's an empty gameObj

[spring creek]

Ok... and what about the script you showed us?

[slate trellis]

The camera script is placed on the camera holder

[spring creek]

If you have a public field (or one with [SerializeField]) i would just drag it in throught the inspector.

[slate trellis]

the Car and Player script are placed on the parent of the objects (Both empty objects)

[spring creek]

Otherwise you have to find it in the scene

[slate trellis]

[SerializeField] GameObject player;
[SerializeField] PlayerMovement playerMove;
[SerializeField] Transform cameraPosPlayer;
public Transform cameraPosCar;
public CameraLocation cameraLocation;

those are the variables

all dragged in place

[buoyant crane]

Sorry got distracted, you have to debug why cameraScript is null

[slate trellis]

void OnCollisionStay(Collision collision)
    {
        if (collision.collider.gameObject.TryGetComponent<GetInCar>(out GetInCar getInCar) && Input.GetKeyDown(KeyCode.E))
        {
//38        cameraScript.cameraPosCar = getInCar.cameraPos; // this line here
            getInCar.rotate = true;
            changeToCar = true;       
        }
    }

I want to debug the highlited line

[spring creek]

Wait, where are you getting the cameraScript variable from then?

And he means YOU debug it, in your ide and unity. Talking to people isn't debugging it

[slate trellis]

I feel confused

[spring creek]

Use debug.log or even better, use breakpoints

[slate trellis]

why is one person helping me and one lecturing me?

[spring creek]

You mean me? I'm helping, but ok, I'll stop

[buoyant crane]

We’re both helping

[slate trellis]

ik, but it get's confusing when 2 people try to make differing points

[buoyant crane]

cameraScript is the only thing that can be null in that line

[slate trellis]

which makes the one look like a lecturer

[buoyant crane]

fair

[spring creek]

I'm confused because we're saying the same things... but I get it can be confusing with more than one person, so I will stop responding. Good luck, truly

[slate trellis]

ah yes, that went over my head

thanks a lot

[buoyant crane]

How do you initialize cameraScript in your code?

[slate trellis]

[SerializeField] CameraScript cameraScript;

[buoyant crane]

Are you dragging in a reference?

[slate trellis]

yes

I just did and it fixed it, thanks a lot

[analog aspen]

  Vector3 right = transform.TransformDirection(Vector3.right);
 
  // Press Left Shift to run
  bool isRunning = Input.GetKey(KeyCode.LeftShift);
  float curSpeedX = canMove ? (isRunning ? runSpeed : walkSpeed) * Input.GetAxis("Vertical") : 0;
  float curSpeedY = canMove ? (isRunning ? runSpeed : walkSpeed) * Input.GetAxis("Horizontal") : 0;
        
  float movementDirectionY = moveDirection.y;
  moveDirection = (forward * curSpeedX) + (right * curSpeedY);```
Hello, how do I fix an issue where the player moves faster diagonally? Above is my code attached to character controller

[cosmic rain]

You need to get the movement direction vector and normalize it before multiplying by speed.

[novel sundial]

Of course, but this code is wrapping Netcode RPC calls so I definitely don't want it running every frame.

[analog aspen]

Vector3 forward = transform.TransformDirection(Vector3.forward);
Vector3 right = transform.TransformDirection(Vector3.right);
 
// Press Left Shift to run
bool isRunning = Input.GetKey(KeyCode.LeftShift);
float curSpeedX = canMove ? (isRunning ? runSpeed : walkSpeed) * Input.GetAxis("Vertical") : 0;
float curSpeedY = canMove ? (isRunning ? runSpeed : walkSpeed) * Input.GetAxis("Horizontal") : 0;

float movementDirectionY = moveDirection.y;
Vector3 normalizedMovement = (forward * curSpeedX + right * curSpeedY).normalized;
moveDirection = normalizedMovement * Mathf.Max(Mathf.Abs(curSpeedX), Mathf.Abs(curSpeedY));

moveDirection.y = movementDirectionY;```
Is this alright?

[spring creek]

Is this all in update?

[analog aspen]

yup

[cosmic rain]

1. Instead of TransformDirection, you can use transform.forward/right directly.
2. Not sure what that weird math is. You should get the input direction first from your input. Normalize it and then multiply by speed. I don't understand why you calculate movement separately for each axis..?
   All you need is:

Vector2 input = new Vector2(xAxis, yAxis);
input.Normalize();
Vector3 movement = input * speed;

Ah, if you follow my example, you'll need to transform the vector into the object space in the end.

[latent latch]

Trying to figure out the best way to make a list of unique values (enums) that can be serialized on the inspector for asset creation, which will also be read multiple times during runtime. The obvious answer you'd think would be a bitwise enum, but depending on the size of the enum, I'd have to loop over every bit to find all set bits before seeing if those keys exists in the dictionary. Any other suggestions?

[analog aspen]

ah alright I get it now ty

[cosmic rain]

What's the problem of looping it?
Also, if you want to check a specific value, you can do bitwise & to see if it's included in the bitmask or not.

[latent latch]

Right, actually all keys do exists in the dictionary, but depending what's in the list will be what events I trigger

so if I had all entries of my flag enum filled up, that's quite a lot of looping each time I check it

[cosmic rain]

32 iterations at max. And you'd need to loop regardless. Even if it was an array or list of values.

[latent latch]

I guess I could just onvalidate and cache the exact keys

[cosmic rain]

Unless I'm misunderstanding your use case.

[latent latch]

right, i have to loop regardless if it's a bitwise enum, but if I just had a list of value I'd know for sure what those values are and the it would just be a O(n) operation

[cosmic rain]

I guess so. The tradeoff is between memory used and runtime complexity.🤷‍♂️

[latent latch]

I just hate using onvalidate honestly but that's usually the fix to the editor's shortcomings

[cosmic rain]

You can make a context menu function that you run manually.

Instead of OnValidate

[latent latch]

ah, hmm

[fast belfry]

Is there a way to do something when PlayableBehaviour starts? And I mean not when it's state becomes Playing, but when we reach it in the track. So basically do something on its first process frame.
Currently I check for whether the action has been taken. Is there anything built in for that? (OnGraphStart and OnBehaviourPlay don't work in that manner?)

[tender coral]

Start() Awake()? 😄

[dull yoke]

Hey guys! My friend @magic island has a problem with this camera jitter/jumping. They already tried capping the FPS to 140 and 60 and changing Update() to FixedUpdate() and Time.deltaTime() to Time.fixedDeltaTime(). Both approaches didn't really solve the issue.
See video for what I mean, you can clearly see the jumping of the camera, even though we have lots of FPS / I move the mouse slowely.

[fast belfry]

PlayableBehaviour doesn't receive those messages

[cosmic rain]

This kinda looks like performance spikes. Your friend needs to come here himself and share some profiling data.

[fast belfry]

And considering graph architecture it would trigger those the same time as GraphStart

[dull yoke]

Aight, they are looking at the profiler right now. Should they share a video or a picture?

[cosmic rain]

A screenshot should be fine.

[soft shard]

One note with the profiler, the "Deep Profiling" mode can help check where GC.Alloc calls may be coming from, which can often contribute to performance issues as well, but its not enabled by default

[magic island]

yeah there are some performance spikes

[dull yoke]

Yes, we have never used the profiler, so we don't really know how it works or what we have to look out for

granted, we've never encountered that camera issue

[magic island]

something certainly causes some performance spikes

[cosmic rain]

It's very hard to see the numbers on mobile, but it doesn't look like the culprit.

Either there's something very weird with your camera controller, or it's something with your machine.

[dull yoke]

Machine shouldn't be the issue, since we have tried it on 4 different devices, all of them using different hardware

Is it okay to share the camera script in here?

[cosmic rain]

That looks more like it.

Most of it seems to come from the editor loop.

[cosmic rain]

Yes, if you follow the code sharing guidelines. But before that switch the profiler to editor mode and take another screenshot of a spike.

[mossy snow]

and profile an actual build too, to confirm you aren't chasing ghosts based on that last screenshot

[cosmic rain]

If the render thread is any indication, it looks like you are playing some video in the scene?

[dull yoke]

Yes. there are some videos inside the building/scene, however, they only play once you get near them and the problem percists outside of the video zones.

[magic island]

it plays a lot of videos actually

[dull yoke]

ah right, you are right

[cosmic rain]

On this frame it seems like it's waiting for something on the GPU thread.

[cosmic rain]

That's the issue probably.

Playing videos is not a "child's play". It's a serious business. If you run several players at the same time, they're gonna do some awful stuff to you.

[magic island]

yeah i should implement some code to only play them when i am near them, hopefully that fixes the issue

[dull yoke]

Alright, so that works good enough. We only play and load one video at a time minus the preloading we do when the app starts up. The performance spikes are almost completely gone - they still happen when you go near a videoplayer, though. It's not noticable enough to consider it annoying now. Thanks @cosmic rain for the advice!

[distant barn]

okay np

[forest linden]

speed = Vector3.Distance(transform.position, lastpos) / Time.deltaTime;
lastpos = transform.position

this is giving me the result 0 every time
I've debugged it and for some stupid reason transform.position and lastpos returned the same value (i debugged it between the spieed calc and the last pos change)
Why?

There are no other instances where i change lastpos

[ashen yoke]

is it in fixed update?

[forest linden]

no

[ashen yoke]

whats the type of speed?

move the whole thing to LateUpdate see if it fixes it

[forest linden]

ok, it worked.

strange tho

that usually always works in a normal update for me

[ashen yoke]

not strange, the issue is execution order

you are testing for transform change before it occured

[forest linden]

ah

ok

[ashen yoke]

i assume some other script moves the object

[forest linden]

the same

[ashen yoke]

are you moving it with physics?

[forest linden]

no

charactercontroller

[ashen yoke]

that is physics

its part of it, even tho doesnt look like it

[forest linden]

I guess its because it calculates collisions

[ashen yoke]

you may look into sync transforms online

that may work, i dont know

[cosmic rain]

We need to see more of your code. It's totally not clear what you're doing from that snippet and where/what you debug.

[vocal root]

Anyone knows a way to write at the start of a string? I need to add text above text in a string but I can't find anything on Google.

[lean sail]

What did you google, because I find it very odd you cant find anything on google for this very common task

[vocal root]

add text to the start of a string unity
tmp text inverse order
invert string order unity

All ive found is to put Line Spacing -1 but only works with old text not tmpro

And I just did it right with something I figured but its weird to not have something to reverse order in strings or texts

[lean sail]

All you need to do is concat the string like
someVar.text = someString + someOtherString
Possibly with a \n in there

[vocal root]

yeah i just did that, but i wanted something to just inverse

[lean sail]

Although you should use stringbuilder instead of any string concat to avoid allocations

[crystal dagger]

Heya

[lean sail]

Inverse meaning reverse the string? Or something else

You could probably just get the char array and call Array.reverse in that case, not sure if theres a more optimal method

[vocal root]

Bread
Chocolate

to

Chocolate
Bread

invert order

[crystal dagger]

Maybe a for that goes on reverse

[lean sail]

Then just concat bread at the end instead of the start.. not entirely sure what you want otherwise

[vocal root]

or add the text to the start so it works the same for me

[crystal dagger]

for(int i = array.len, i < 1, i--)
array[i]

actually --

[lean sail]

Why add it to the start and then try to invert, instead of just adding to the end

[vocal root]

no no, its one thing or the other

i just needed one

im trying to make like a history of text written

and i want the newest at the start

but nvm i just did the concat of the previous history to the end so i add the new text at the beggining

[lean sail]

Definitely use stringbuilder then

[crystal dagger]

So i need help

        float distance = Vector3.Distance(character.position, zombie.position);
        if (distance < 10)
        {
            Vector3 direction = zombie.position - character.position;
            Quaternion rotation = Quaternion.LookRotation(direction);
            head.rotation = rotation;
            rotation = Quaternion.Euler(character.eulerAngles.x, Mathf.Clamp(head.eulerAngles.y, character.eulerAngles.y-90, character.eulerAngles.y+90), character.eulerAngles.z);
            head.rotation = rotation;
        }

This is my current code, the goal is to look at the enemy when they're nearby

Problem is, at some angles, the head flips suddenly to the wrong direction

[unborn pollen]

Hi is there a way to apply a shader to the Unity UI?

I have a canvas screen space, which I can't change to another space it has to stay in this one.

I can't find a way to get a colorblind shader applied to this UI in this space.

Because the canvas screen space UI looks like it's rendered outside of the unity pipeline.

I also try to create my own scriptable render pipeline, but even if you create a null one and all the render is black, the canvas screen space is render over all the previus render.

[sudden meadow]

If I have a database of scriptable objects that contain object data, can I copy that SO class into an object in a smart way so that it's not a direct reference making me able to alter the SO variables without it reflecting on all other objects that use the same SO data?

I'm looking at ICloneable (https://learn.microsoft.com/en-us/dotnet/api/system.icloneable?view=net-7.0), do you think this would be appropriate??

[unborn pollen]

Yeah i have use IClonable interface to do that, but some times i have problem with the child objetcs.

For example, it copy the data from a class, but if inside that class there is a member that have a direct reference, the direct reference will persist in your copy

[sudden meadow]

Yeah I saw that when it came to deep vs shallow copy but that should be okay. I only need a shallow copy so I can alter a few variables. Thanks.

[sudden meadow]

Seems doing Instantiate might be a better idea. Clone worked. I could alter the variables and read them separately on each object, but for some reason the original also got changed.

[steady moat]

You should consider other pattern then copying a ScriptableObject.

[sudden meadow]

why

[steady moat]

Usually, you have something that represent the instance and something that represent concept.

By example, If I say: Give me X weapon, I'm talking about the concept. If I say give me the weapon of the player, I'm talking about the instance of the weapon.

Variable are different on both object.

In one situation, the variable is the same for every weapon that is associated with the given SO.

You can see this as the FlyWeight pattern.

https://en.wikipedia.org/wiki/Flyweight_pattern

[sudden meadow]

nah the reason i want a shallow copy is because i am storing behavior scripts as SO's for plug and play behavior scripting, and I want the behavior itself to have local internal playtime and behavior stage tracking.

[steady moat]

This is exactly what I am doing currently and it does not work well. Instead, use something like what Unity has done with Visual Scripting.

huh

well I guess I figured it out??

[hidden gulch]

how do i calculate the amount of torque needed to reach a certain rotation?

p.s. using rigidbodies

[eager wagon]

hi
I want to access a script from a prefab (public cannon cannonScr;), but it doesn't appear when I want to integrate it in the Unity inspector. Do I need to do it differently with prefabs?

[fervent furnace]

is your prefab in scene?

[eager wagon]

no

i Instantiate it

[fervent furnace]

try getcomponent?

[eager wagon]

??

[fervent furnace]

object in scene cannot reference script of prefab in folder but you can use get component to get its script when instantiate
or you have tried but it doesnt work

[eager wagon]

idk who to do this

i mean with a script

the fact is that i Instantiate a prefab and i want get a var from anotehr script

[fervent furnace]

you mean the spawner want to access some scripts on prefab? or another script not on the prefabs (on other gameObject)?

[eager wagon]

the boject i spawn (the bullet) i want to get a var from the gun scr

[stark sinew]

@hidden gulch

I'm not exactly sure, but maybe Kinematic Equations can help you.

You could also divide the amount of rotation by the amount of time you want it to take to get the needed per-frame rotation value, but idk if that's working properly with Rigidbody

[hidden gulch]

alr, ill take a look at that.

[fervent furnace]

oh so the prefab wants to access the variables on spawner script
declare a property on bullet's script and the gun pass its script to it
instantiate().getcomponet<>().gun script=this

[eager wagon]

i see

i think it should work

thx

[eager wagon]

idk if im doing it bad but it doesnt work

[stark sinew]

@eager wagon
Could you show some code?

[eager wagon]

yep

GameObject cannonBallInstanciada = Instantiate(cannonBall, transform.position, Quaternion.identity).GetComponent<>()cannon.angles;

i trieed to replicate this
instantiate().getcomponet<>().gun script=this

[stark sinew]

Bro wtf is GetComponent<>()cannon 😄
That other person wrote some pseudo-code, you gotta make it fit for your project.
At this point, I think you're better off in the beginner channel!

someObject.GetComponent<SomeComponent>().someProperty = someValue;

Pseudo-Code, don't copy paste this, modify it accordingly!

https://m.youtube.com/watch?v=jGD0vn-QIkg&pp=ygUJQyMgYmFzaWNz

[eager wagon]

idk

just tried waht this guy said

[eager wagon]

yes but whats the way to get a variable when i Instantiate a object

[stark sinew]

var theObject = Instantiate(...)
theObject.theVariable = ...

Still, pseudo-code, don't copy paste.

But seriously, watch some Videos and move to Beginner

[fervent furnace]

you already referenced to the object have you spawned so you can getcomponent on it

[rigid island]

brackys c# tutorials are dumpster fire

[stark sinew]

@rigid island
Brackeys sucks.
But for someone who's mindlessly copying and pasting, it's enough to learn the basics!

[rigid island]

why link it lol

[stark sinew]

Why not give some useful advice to this person instead of questioning mine?
You shouldn't complain about answers while you're not giving any on yourself!!

It's not about the specific Content Creator, it's about the severe need of learning the very basics, if you write something like GetComponent<>()cannon.angle you can pretty much watch Brackeys to improve.

Just search for C# Basics and there are probably 20 more people teaching them, choose whom you like.

And still, #💻┃code-beginner

To be absolutely fair, if you're learning C#, do it outside of a Unity Context and come back to Unity once you grasped the fundamentals, it'll click much much faster for you this way, else you'll probably jump from one Tutorial to the next one, hoping that they'll complete the game on their own, which they won't.

will simplify the question cos i think u dont underestand me.
i have a gun. the gun can create bullets. the bullet spd is a var from the gun. i want get the scr of the gun like this: public cannon cannon;
teh problem is that when i try to put the script in the unity inspector i cant (cos teh bullet is a prefab i underestand). So now this guy told me that i can modify a variable when i Instantiate the object.
the way u told me aint working for me, since when i try to TheObject.var it doesnt works

[stark sinew]

my friend, please just watch some C# tutorials, you'll thank me in the long run 🙂

It's not my job to solve your problems, it's nobodies job, it's our job to guide you towards the correct direction and give you some advice, which I did in the best possible way.
If you're going to accept it or not, that's on your side.

One more pseudo for you:

void ShootBullet()
{
  var bullet = Instantiate(...)
  bullet.speed = this.bulletSpeed
}

Tbh, IMO, you shouldn't get any more responses in THIS channel, at least take it to Beginner and admit that this is what you are.
You seemingly don't want to learn, you want us to give you the solution.

@n.navarone just stop bothering, this person doesn't want to understand, and we're wasting time and energy here

[eager wagon]

i see

u wont solve my problem true

anyways

[rigid island]

you have to have some basic understanding about accessing variables in scripts

you can't just skip the basics

[eager wagon]

man pls i studied programming for 2 years dont disrespect me like this

[rigid island]

whatever it was, it was not C# so that knowledge is irrelevant

[eager wagon]

i wached a 127 vidios tutorial before this

[rigid island]

https://learn.unity.com/project/beginner-gameplay-scripting

you need a structure course,not random vids

[eager wagon]

no way

wont get teh solñution here

[rigid island]

the solution is you learning the basics

you were given a solution, because you don't understand the basics you don't understand the soltion..

[robust dome]

you just want to be spoonfed which is not ok.

you should learn some basic stuff first

[static matrix]

quick question:
BehindWoods = new List<GameObject>(AheadWoods);
this assigns BehindWoods to a new list and then fills the list with the contents of AheadWoods, correct?

[rigid island]

yes

[static matrix]

great

[stark sinew]

Yes, but I am not sure if it'll reference the original AheadWoods or if it's copying them (in case it's a reference type)

[fervent furnace]

it will not deep copy i think,
i have to check the source code

[static matrix]

ahead woods is another list

I think this will work

hopefully

[fervent furnace]

the source code....
there should be no generic solution to deep copy something

[static matrix]

what does deep copy mean?

[rigid island]

deep copy means it creates a new object based on the copy but it's entirely new object

shallow copy means it copies the object but still holds the same references

[static matrix]

which means if I change the original, I will change the copy?
Or no

[rigid island]

a shallow copy would

[static matrix]

unfortunate

[rigid island]

might be worth a read
https://code-maze.com/csharp-how-to-clone-a-list/

[static matrix]

I can use CopyTo it looks like

ill figure it out

[ashen yoke]

there is also AddRange

[static matrix]

maybe
basically what im trying to do is a staggered moving of a bunch of objects

 WaitToMoveTarg += Time.deltaTime;
            if (!IsVis)
            {
                awaitWoodMove += Time.deltaTime;
            }
            if(WaitToMoveTarg> 8)
            {
                if (BehindWoods.Count > 0 && awaitWoodMove > 0.8f)
                {
                    var moveWood = BehindWoods[Random.Range(0, BehindWoods.Count)];
                    BehindWoods.Remove(moveWood);
                    AheadWoods.Add(moveWood);
                    MoveWood(moveWood);
                }
                else
                {
                    BehindWoods = new List<GameObject>(AheadWoods);
                    AheadWoods = new List<GameObject>();
                    Orient.transform.position = Target;
                }
            }

this is the code rn

[pure cliff]

Still having this issue, anyone encountered this before and know how to fix it?
#archived-code-general message

[static matrix]

can one audiosource overlap with itself or does it start over if you play it again while its playing

[rigid island]

iirc Play() will reset / PlayOneShot overlaps

[static matrix]

woah
time to replace
all of play with playoneshot
no bad outcomes will come of this im sure

oh wait its funky and different
ill figure it out

[spark yew]

i don't really know the specific keywords/terms i have to search up to make this but how would i be able to create a circle of buttons that rotate when you cycle through them

like the mario and luigi system

[pure cliff]

pseudo 3d in 2d, or actually 3d?

[spark yew]

pseudo 3d if that works

[pure cliff]

prolly would be fine to slerp both its translation to the next spot, while also slerping its scale

[hasty haven]

Is there a way I can go without allocating garbage here
meshRenderer.materials = newMaterials.ToArray();
The new material list can vary in length and id prefer to use an array + count variable
Profiler shows .ToArray() is allocating garbage

[pure cliff]

Though you'll need the ones going "back" to slerp the opposite way to the ones going "forward"

[pure cliff]

that entirely depends on how you are building that list of new materials

[ashen yoke]

the only thing you can do is initially use an array

[pure cliff]

But effectively what you need is to just know how big the array is gonna be before you start filling it and you are golden

[hasty haven]

Makes sense, that was my original approach and I just made it 256 in length but that KILLED performance super badly

even though I only need 3 ish elements right now

[ashen yoke]

never tried something like that, interesting

[hasty haven]

it allocated 0 garbage but was bad lol

[ashen yoke]

guess it attempts to create new submesh groups for each index

anyway, just do ToArray() once

its not garbage if it doesnt get collected

[hasty haven]

Its the only part of my code which allocates garbage every time a chunk is modified
I could switch to advanced mesh api later on probably but its performant as is

[ashen yoke]

i guess you update materials based on what voxels chunk has?

[hasty haven]

Thats what I'm doing, ill just paste the method

[ashen yoke]

https://docs.unity3d.com/ScriptReference/Renderer.SetMaterials.html

[hasty haven]

List<Material> newMaterials = new List<Material>();
  private void UpdateMesh() {
      thisMesh.indexFormat = IndexFormat.UInt32;
      thisMesh.Clear();
      thisMesh.subMeshCount = 0;
      colliderMesh.Clear();

      // Apply vertices
      thisMesh.SetVertices(vertexArray, 0, vertexCount);
      colliderMesh.SetVertices(colliderVertices, 0, colliderVertexCount);
      colliderMesh.SetTriangles(colliderTriangles, 0, colliderTriangleCount, 0);
      
      // Grab appropriate materials for submeshes
      newMaterials.Clear();
      for(int i=0; i<trianglePartitions.Length; i++) {
          if(trianglePartitions[i].capacity > 0) {
              thisMesh.subMeshCount++;
              newMaterials.Add(BlockDataManager.Instance.blockMaterials[(BlockType)i]);
              thisMesh.SetTriangles(triangleArray, trianglePartitions[i].start, trianglePartitions[i].DataLength(), thisMesh.subMeshCount-1, false);
          }
      }
      
      meshRenderer.materials = newMaterials.ToArray();
      thisMesh.RecalculateNormals(UnityEngine.Rendering.MeshUpdateFlags.DontValidateIndices);
      meshCollider.sharedMesh = colliderMesh;
  }

I have a giant array for triangles that i split into partitions

so each material starts at its own index and has a capacity in the triangle array, thats what the for loop is for

It seems like the physX calculations with mesh collider is the biggest chunk of performance now but it works fine for now

[ashen yoke]

you can completely avoid using multiple materials

if you use a shader tilemap shader or texture3d

[hasty haven]

Ah as opposed to using one sprite sheet and splitting the UV up?

I'm not using any textures right now, deciding on how i want to do things

[ashen yoke]

all cube faces have same uv

you "paint" them with indexed color

each R value 0-255 represents an index in the atlas

shader selects that index with frac

you are offseting uvs on the shader

[hasty haven]

Oh i see, i could probably do some blending between types with that as well?

I remember the game cube world had some pretty gradients

[ashen yoke]

with this approach blending probably wont be possible, but i havent tried

what do you mean by blending?

alternative to a single atlas is using 3d texture

so you select the texture from the array instead of shifting uvs on the atlas

also on the shader

[hasty haven]

Ah thats cool, may look into that later

I spent this past week working on getting this to work with beveled edges
