# cosmic gorge yeah. but i personally enjoy it

always thought it was cool! i started a quote-unquote indie game studio with my friend when i was younger (we had no idea how to code and just wrote shit down in notepad thinking our game would magically spring to life)

#

so yeah i think its fun learning unity ngl

#

Is there a way to have the UI buttons from the UI Builder appear in the Gamescene?

#

Mainly to make sure that I can actually interact with the buttons in-game.

abstract copper
#

yes

astral falcon
#

And what does the error say?

abstract copper
#

The type or namespace name 'TMPro' could not be found (are you missing a using directive or an assembly reference?)

astral falcon
#

Oh wait, you want to change unity build in scripts?

abstract copper
#

yeah its from a sample

astral falcon
#

In that sample, there might be a assembly definition file, you have to link TMPro in there, so that package knows, what TMPro is

abstract copper
grand snow
#

edit it in unity...

#

If you are using a asm def you add the reference to TMPro on that

abstract copper
#

oh i see

#

thanks

grand snow
#

the "auto" Assembly-CSharp does this all automatically cus you cant edit it. Using asm defs is better in the long run so good to get used to it

#

Be warned that old code or libs that dont have asm defs added cannot be referenced so you have to add them yourself 😐

My editor completely freezes when I call this method across a few hundred objects, is this expected?

#

I thought it could handle those collisions

naive pawn
#

i mean yeah that is a significant amount of work

sharp bloom
#

Shit I'm running out of options to figure out neighbors for randomly generated cube objects (voxels)

#

Never did procedural generation before xd

#

I was mostly just wondering about the freezing and crash when using that OverlapBox

naive pawn
# 
// 3d adjacent neighbors
Vector3Int pos = ...;
for (int dx = -1; dx <= 1; dx++) {
  for (int dy = -1; dz <= 1; dy++) {
    for (int dz = -1; dy <= 1; dz++) {
      Vector3Int offset = new(dx, dy, dz);
      if (offset == Vector3Int.zero) continue;
      Vector3Int neighborPos = pos + offset;
      // ...
    }
  }
}
night raptor
sharp bloom
#

Yea for sure. I did the generation just purely with Random.Range values xd

night raptor
#

Some sort of (pseudo)random values are always required for random procedural generation

teal elk
#

How would I fix this? I'm using Sebastian Lague's Path Creator tool. I can use the path tool in the Unity editor, but I can't seem to get it to recognize the Path Creator namespace so I can use it in code.

that's what I thought

#

Worked yesterday atwhatcost

night raptor
#

OverlapBox is definitely not the best solution but it shouldn't be that bad

astral falcon
night raptor
#

yeah, while, for or infinite recursion

naive pawn
#

infinite recursion would probably break eventually with a stackoverflow

night raptor
#

although infinite recursion might actually cause an stackoverflow and not crash, i'm not sure

naive pawn
#

so probably not that

astral falcon
#

But without code, we wont know 😄

sharp bloom
#

Yes it was infinite loop, I had messed with my tags and that had broken one of my scripts 🫡

Quick question. Learning some new things with GameObjects and not using GetComponent() (instead just doing the Compoent component way), but having trouble changing the variable of another script this way. It did not work either when doing GetCompoent(), so I am unsure of why it is breaking. Where is the code to change the other scripts variable:

    public void Start()
    {
        
        AddCardImage();
        hand.handValue = hand.handValue + cardValue;
        Debug.Log($"CardValue " + cardValue);
        UISprite.sprite = cardSprite;
        
    }
``` I DO get a variable for cardvalue, just hand.handValue always stays 0. Is there something I am doing wrong with this code? Do I need to show more info? Generally just confused at the moment.
grand snow
#

put a break point before you set it and observe the before and after value

untold shore
#

Oh hey! thanks for the tips yesterday. Let me check rq...

grand snow
#

if its a property you can step into it if you are debugging to see what it actually does

#

and when i say "debugging" i mean attaching a debugger (https://unity.huh.how/debugging/debugger)

🤔 Unity, Huh, How?
The debugger

The debugger is a tool that halts code execution. Values can be inspected, lines of code can be stepped over, and sometimes even modified. This does not require recompiling your code, or exiting Play Mode.

untold shore
#

If it helps real quick, here is all the code related to handValue. Very small

{
    [SerializeField] public int handValue = 0;
    public TMP_Text handValueText;
    
    public void Update()
    {
        handValueText.SetText("HandValue: {0}", handValue);
    }

}
``` Doing debugging rq, here the weird part - it keeps saying 100+?
image.png
grand snow
#

plz use a debugger like i said. If the field is not the value you expect then it must be changed elsewhere or its not what you expect at the time of the addition

#

logs only get you soo far

wintry quarry
#

Also what's going on here? Are you spawning in a prefab or something?

#

print HandValue before and after updating it

untold shore
#

It should always start at 0. Yep, spawning in a prefab (card) that has a value, and it should add its value to handValue

#

Will do

wintry quarry
#

Methinks you are actually incrementing a variable on another prefab

#

not on the instance in the scene

untold shore
#

Hope this is what you asked for? It's the HandPosition one

image.png
wintry quarry
#

is this a screenshot of a prefab?

wintry quarry
#

If that's a screenshot of a prefab then it must be referencing another prefab

untold shore
#

It is, HandPosition is a prefab

wintry quarry
#

look at the prefab

#

not the one in the scene

#

that's the value you are incrementing - the one on the actual prefab in your assets folder

untold shore
#

So Im incrementing this one here?

image.png
wintry quarry
#

Maybe? YOu have to check what you're actually referncing

#

you can click on the referenced thing and it will take you to it

#

You're either referencing the prefab, or an instance of it in the scene

#

Note when I asked "is this a prefab?" I mean "is it a prefab in the assets folder?"

#

things in the scene are not prefabs

#

They can be instances of a prefab, but not prefabs themselves

grand snow
#

Yea easy for beginners to accidently modify the prefab asset and not an instance of the prefab.

faint osprey
#

im having some trouble with getting the mouse position as a vector3 im doing this atm

mousePos = mousePos - g.transform.position;```

to get the direction from my gameobject to the mouse but its not working as intended
wintry quarry
#

it's the position in pixels on your screen

#

you cannot directly do math with that and world space gameobject positions

#

They are in completely different coordinate spaces

faint osprey
#

so what should i do instead

wintry quarry
#

That depends on what you are actually trying to accomplish here

#

what's the goal?

faint osprey
#

when i instantiate my bullet so its transform.up to the vector between my player and mouse

wintry quarry
faint osprey
#

yes

untold shore
#

Yeah, its referencing the prefab in the prefab folder. What I want it to change is the HandPosition here, should I reference it differently?

grand snow
#

make it reference the instance of said prefab in your scene...

#

drag and drop!

wintry quarry
# faint osprey yes

You need to convert the mouse position into a world space position. E.g.:

Vector3 mousePos = Input.mousePosition;
Vector3 mousePosInWorld = Camera.main.ScreenToWorldPoint(mousePosInWorld);
mousePosInWorld.z = 0;

Vector3 direction = mousePosInWorld - g.transform.position;
g.transform.right = direction;```
wintry quarry
faint osprey
wintry quarry
# faint osprey thanks

Note this method will only work if you are using an Orthographic camera projection, which is the default in 2D.

untold shore
# grand snow drag and drop!

That's the thing though - cardPrefab isnt added into the screen until after Start(), so I have to go into the cardPrefab (I think) to change it. Do I need to change HandPosition's prefab?

grand snow
#

make sense?

#

Its not going to work if you dont reference the instance and modify values on that instance is it?

untold shore
#

Yep, that makes way more sense! Thanks. Yall are so helpful for my non coding brain 😭sadok

grand snow
#

Its important to understand instances. The prefab is the "template" that you make copies from.
Therefore you need to have a reference to the copy you want to change stuff on.

untold shore
#

Will do! I defiently need to watch a ton more videos on things like this, lol.

#

There we go, it immediately worked. Thank you so so much!!!

im making a small project so i think illt ry the scenes out

wintry quarry
#

Generally you use scenes when you need different baked lighting and static objects and occlusion culling

#

if not, just use prefabs

I would like for the ray to go toward the black triangle in the x axis and keep the y axis of the blue triangle. I have tried changing the second vector to a direction instead of a vector and i still got the same result. Also how does the distance work because if i make the distance 10f instead of 1f, a 10x increase, only doubles the length of the ray.

image.png
wintry quarry
#

DrawRay takes a position and a direction

#

You are passing in two positions

#

If you want to pass in two positions, use DrawLine

#

Your raycast, similarly, is borked

#

you are passing in two positions

#

If you wish to pass into two positions, use Physics2D.LineCast instead

#

otherwise you must pass in a position and a direction

stark hill
#

okay thank you i will try that

wintry quarry
#

if i make the distance 10f instead of 1f, a 10x increase, only doubles the length of the ray
This is not true and simply related to:

  • The hit point isn't always the full distance. The distance is just the max distance. It can hit objects before that
  • Your improper use of DrawRay means you're not drawing things properly anyway
wintry quarry
#

e.g.

if (hit.collider != null) {
  Debug.Log($"We hit {hit.collider}");
}
else {
  Debug.Log("Didn't hit anything");
}```
stark hill
#

i have the debug log hit or does it return something no matter what?

wintry quarry
#

if the raycast didn't hit anything, all the data in hit will be empty basically

wintry quarry
#

the data inside the hit struct is going to be nonsense/garbage if it didn't actually hit anything

#

so it can't be used for drawing anything in that case

stark hill
#

oh okay

#

I found some figure eight code on the internet that works perfectly but my problem is I only want to do a single figure eight.. how do I know at what time this will have gone through a full cycle based on its speed? I did a test and 1 speed = around 12.57 seconds if that helps.....

transform.position = startPos + (Vector3.right * Mathf.Sin(time / 2 * speed) * xScale - Vector3.up * Mathf.Sin(time * speed) * yScale);```
wintry quarry
#

since it's doing time / 2

#

this will be 4PI

#

i.e. ~12.56

#

so your estimate/test is roughly accurate

plush chasm
#

okay thanks, so then I just divide that by the speed and that should be the total duration for any speed

wintry quarry
#

I would get rid of the / 2 which is arbitrary

brave compass
#

It's necessary to make the figure eight. It needs to cycle twice as fast on one axis than the other.

wintry quarry
#

I would do this:

float desiredDuration = 5; // i.e. 5 seconds
time += Time.deltaTime;
float theta = time * ((Mathf.PI * 4) / desiredDuration);
transform.position = startPos + (Vector3.right * Mathf.Sin(theta / 2) * xScale - Vector3.up * Mathf.Sin(theta) * yScale);```
wintry quarry
#

then you need 4pi

#

I believe my code snippet above will work and you can plug your desired duration into that first variable

#

It's just off the top of my head though so it's possible I erred

#

(I just changed ((Mathf.PI * 4) * desiredDuration) to ((Mathf.PI * 4) / desiredDuration) which I believe is correct)

hard lodge
#

is this how you load a scene?

Screenshot_2025-01-17_161523.png
wintry quarry
#

SceneManager.LoadScene is a way to load a scene, sure.

hard lodge
#

it does not work for me tho :(

wintry quarry
#

It's probably not running

#

or you have errors

#

As suggested above you should add Debug.log to this code to make sure it's actually running

#

both before and after the if statement

hard lodge
#

Yeah

b/c the object becomes a child of an object.. the one that rotates..

#

if its scale isn't 1:1:1 when u do rotations its gonna skew and warp the child

wintry quarry
dawn hedge
wintry quarry
#

rule of thumb: any object that has one or more children should not be scaled.

#

or at least - only scaled uniformly (same on all axes)

rocky canyon
#

if u have objects that need scaling always keep them seperate..

  • Main Object <-- this object would remain scaled 1:1:1
    • Graphic <-- this object represents the actual object and would be the thing scaled
#

then if u grabbed "main object and rotated it around the graphic would follow along (w/o any weird skewing)

Hi Unity people, I am wondering something: Is it possible to display a wireframe cube that only contains 12 edges? There are cubes defined on Unity, but if you show them, there are more than 12 edges (there are bars in the diagonal of each side)

#

my intent is to display a 3D box around a person for AR applications. I can do that with the current cubes, though there are these annoying diagonal bars on all sides that make it hard to see through

are there some specially designed cube meshes that are already like this? I could use them from internet. Otherwise, with LineRenderer, how does it work? I can select the lines that I would render ?

wintry quarry
spark sinew
#

thanks

wintry quarry
#

are there some specially designed cube meshes that are already like this
I dunno, I was thinking you'd make one. Note that all meshes use triangles so this would be like a mesh that's actually the "framework" so to speak

spark sinew
#

I am a little bit confused on linerenderers, how do I modify this? I can see the meshrenderer

wintry quarry
spark sinew
#

ok

wintry quarry
#

In the LineRenderer you add the points you want and it draws a line between them.

spark sinew
#

Oh, I see, so you have to completely draw the cube with each vertex defined as a 3D vector and define lines between them ?

wintry quarry
#

It just takes a sequence of positions and connects the dots

#

A --- B
|
C

rocky canyon
#

u can have as many as them as u need

#

can add them in the inspector.. or anytime during runtime with a reference to the line renderer

spark sinew
#

I see, thanks. Too bad that there is not something built in. I will probably work on this later as it is less easy than working with 3D objects

"is just resetted"?

#

if the scene lighting looks wrong (notably, if surfaces facing away from the sun light are black), you probably need to generate lighting in the editor

Hey, having some issues with a new error message I haven't figured out how to fix. I keep trying to figure out WHY dealerDeckManager is null, because it is, but I don't know when it's becoming null.
Script referencing it:

    public GameObject dealerDeckManager;
    public GameObject dealerHandManager;
    public void Start()
    {
        dealerDeckManager = GameObject.FindWithTag("DealerDeckManager");
    }
```I don't know, Ive tried to figure out why DealerDeckManager has been null for the last 30 minutes. Any ideas of why?  (I do know that it is DealerDeckManager, not the script.)  Thinking it has something to do with it being a prefab, but everytime I click the reference it tells me its the DealerDeckManager in the scene. @ me if you respond, thanks.

rich adder
#

also yeah maybe it is because you linked a scene object from prefab, if you spawn more that same reference wont be in the new prefab

prefabs cannot reference sceneobjects (unless they are in the same scene therefore is an instance not prefab)

also you don't need isWalking == true

you can just write isWalking

ill do that now
wintry quarry

t: TraitorAI

faint osprey
#

definitly just one

wintry quarry
#

Add Debug.Log to OnTriggerEnter2D

#

because that sets it back to true

faint osprey
#

oh shit wait yeah

#

yeah its calling twice

#

once when it shod

#

and 2nd when the child collider hits it

wintry quarry
# 
Debug.Log($"Entered a trigger: {collision.name}");``` might be useful as the first line there
faint osprey
#

but surely it shouldnt be calling for a collider on a different gameobject even if it is a child

wintry quarry
#

you will get a call for every collider it touches

#

and yes all of your child colliders are part of you

#

if you have a rigidbody

faint osprey
#

so then how do i use more than one trigger

wintry quarry
#

Sorry misread this as OnCillisionEnter

#

what are you trying to do

faint osprey
#

cause i have a trigger collider on my main one for walking distance and a trigger on my child for attack distance

wintry quarry
faint osprey
#

ive done that yes for the attack one

wintry quarry
#

put the walking distance on a child too

#

and ptu a script there

Does anyone know how to set a sprite renderer to dynamically render a constantly shifting polygon collider? I know how to set a polygon collider to match a sprite but not the reverse, and google is only showing me sprite-to-collider answers because I dunno how to phrase it.

wintry quarry
glad quiver
#

Taking a look now, thanks!

wintry quarry

or - depending on exactly what you're doing - this might be doable with a relatively simple shader

glad quiver
#

@wintry quarry I dunno shaders yet. I’m trying to color a polygon collider 2d with a flat color that lerps.

#

Would learning a shader for that be easier than the spriteshape thing?

#

Btw I know how to do it if I use a mesh, I’m trying to somehow skip generating a mesh from my points, specifically. I don’t even know if that’s possible.

currently i'm trying to "clamp" my camera's movement if it goes to far away from it's origin, but because i'm working in a vr environment i can't just override the camera's position unless i'd like to rework unity's camera script for vr devices
would the best way to move an offset counter-acting the camera's movement if far away? or is there any better solution, been stuck on this for a couple hours so any help appreciated

barren prawn

I think I made a mistake

#

I'm trying to get them to spawn on the sides, with a specific height difference, but it ain't working

cosmic quail
barren prawn
wintry quarry
#

and this whole unit thing seems overcomplex - why not just set these parameters in the inspector instead:

                float lowestPoint = -1 * yOffset;
                float highestPoint = yOffset;
                float y = Random.Range(lowestPoint, highestPoint);
                float x = -12;
                summon(x, y);```
barren prawn
wintry quarry
#

and have the spawner spawn them at its own position

#

rather than trying to hardcode numbers in your code

barren prawn
#

Does that mean I have to make 4 of the unit wall?

wintry quarry
#

I don't know what "4 of the unit wall" means

#

You would make 4 spawners, sure

#

Or just one script that has references to a bunch of empty objects for the positions

barren prawn
#

A spawner is the prefab of the wall entity?

wintry quarry
#

The spawner is the thing that spawns things

#

the prefab would be the thing being spawned

barren prawn
#

Can you place the spawner somewhere?

wintry quarry
#

you can do whatever you want

barren prawn
#

So in the 4 areas, I'll just set the spawn location to different coordinates, then vary the height/width?

wintry quarry
#

I don't understand what you mean by that exactly, sorry

barren prawn
#

I don't exactly know what a spawner is

wintry quarry
#

spawn means to create

#

or instantiate

barren prawn
#

I did make a spawn script

wintry quarry
#

I would just do something like this:

public class Spawner: MonoBehaviour {
  // Assign all these fields in the inspector
  public Transform PointA;
  public Transform PointB;
  public GameObject prefab;

  void SpawnSomething() {
    float random = UnityEngine.Random.value; // random number 0 to 1

    Vector3 position = Vector3.Lerp(PointA.position, PointB.position, random);
    Quaternion rotation = Quaternion.Slerp(PointA.rotation, PointB.rotation, random);
    GameObject spawnedThing = Instantiate(prefab, position, rotation);
  }
}```
#

then you can make empty objects for points A and B

#

and position them wherever you'd like

#

and reference them

#

and it will just work

#

(you'd add the timer stuff in Update and call SpawnSomething() when the time is right)

wintry quarry
barren prawn
#

So in my case I would have 4 points?

rich adder
#

2 on each side

barren prawn
#

And those are just empty creates in Unity?

rich adder
#

you create empty gameobjects so you can position them in the scene then set the references (drag n drop in pointa, pointb)

barren prawn
rich adder
barren prawn
#

Ahh, so an empty create?

#

Or create empty*

rich adder
#

yeah they were empty

#

Oh the slots are buttons

        Button button = slots[i].GetComponent<Button>();

        if (button != null)
        {
            int index = i;
            button.onClick.AddListener(() => OnSlotClicked(index));
        }
    }

    Inventory.Instance.OnInventoryChanged += InventoryInstance_OnInventoryChanged;
    RefreshUI();
}

is the red part like a second object that you're activating?

Maybe it's just blocking the raycasts

Make sure raycast target is disabled on it if it's not supposed to block raycasts.

is there a global scale i can use? lossy scale is get only

swift crag
candid ivy

literally

swift crag

For example, if the prefab's root object has an Enemy component on it, you can reference the prefab as an Enemy, and instantiating the prefab will give you a reference to that Enemy component on the newly-created copy

swift crag
candid ivy
#

thanks for the help I love you

swift crag
#

lossyScale is named "lossy" for a reason -- your world scale depends on the rotation and scales of your parents

#

you've probably seen skewing when rotating an object whose parent is non-uniformly scaled before

stuck palm
#

i see

#

i ended up just changing the scales in the hierarchy

swift crag
#

If you know that your object's parents are all uniformly-scaled, you can calculate the appropriate local scale yourself

stuck palm

just easier

Always keep scale at 1

was reading that non-uniform stuff can create problems for colliders as well

hello i am doing some experiments trying to make my own movement system without a character controller or rigidbody so I've implemented a collision system (using built-in physics though), but I think there's a logical error:

  • It should "simulate" the player going to a position and check if theres a collision and if so, then do a binary search across the vector until there's no collision and calculate velocity from there
    The issue is that I think it's simulating the player in the opposite direction (ie player is going to positive Z, it'll simulate negative Z). It might just be a + and - issue but I can't spot it. Can someone help?

Hi!
Is there any room for improvement for the performance of SetTiles in 2D top-down tilemaps? I was planning to do my own using something like ECS but I still don't have a plan to render just one quad mesh per chunk (is it necessary for it to be per tile? I don't mind having a flat map if that allows me to see more of it at once) each with its own texture. Is that a possibility. I also plan to perform flood-fill algorithms frequently.

teal viper
ornate aurora
#

Yes I already did that and SetTilesBlock is the bottleneck

teal viper
ornate aurora
#

Yes hang on

#

There's also the get chunk thing but I do have a few ideas to fix that. Even if it was 0, the other calls are still too much

teal viper
ornate aurora
#

18% of the time was spent on EditorLoop at the bottom

teal viper
# ornate aurora

I mean expand the SetTilesBlock.
The fact that Self Ms is near 0, means that it's not the method itself, but something deeper the hierarchy.

ornate aurora
#

Ah sorry

#

I didn't expand it because that's just the method provided by unity

teal viper
#

Also, I have a feeling like it's the GC that is at fault here. You're allocating a lot of garbage.

teal viper
ornate aurora
ornate aurora
teal viper
teal viper
ornate aurora
#

No code for the tiles. I'm using the tilemap only as a renderer. The logic is run manually

teal viper
#

Hmm... Do you have gameObjects assigned to tiles?

#

Also, is that in deep profiling mode?

ornate aurora
ornate aurora
#

This is my hierarchy, and those overlays are just quads. NearbyOverlays just has a transform

image.png
ornate aurora
teal viper
teal viper
# ornate aurora Yes

First of all what I'd try is profile a build(with and without deep profiling enabled) and see if the time of that call changes drastically.

ornate aurora
#

Yes that is because the chunks are 16*16 so the GetTileData is called once per tile

teal viper
#

Regarding GC, you should be able to see it in the graph breakdown by color. If you don't see it, it should be fine I think.

#

Lastly, it would help to see your code as well.

ornate aurora
teal viper
#

I can't say for sure, but I think unity should be able to handle 1000 tiles assignment with this method relatively easy.

ornate aurora
ornate aurora
#

Without deep profiling it's not going to let me see the time of that particular call, right?

teal viper
#

Deep profiling can impact performance heavily as it injects timing queries into the code. Cases where there are hundreds of calls can have a huge impact.

whats the proper way of making variable affect another variable

#

i have ready list of 100 items, how should i make them bulk affect player stats

slender nymph
#

what does it mean for a variable to "affect another variable"

rocky canyon
late burrow
#

yeah but thats the thing i dont want to permanently overwrite them

#

just make use of all the items currently carried

rocky canyon
#

well don't.. store a default list and modify a different one

#

theres probably better ways to do that im not sure

late burrow
#

do i have to include every field in the item class and then make loop for each of them?

rocky canyon
#

ya, i looked at my stats stuff and i use structs w/ default values and then create new ones in code to be the modified versions

#

but i think u can use Scriptable objects too..

late burrow
#

like using ints on them would require huge block of data in them

item.add("katana", "20str");
item.add("glasses", "10int");
item.add("shield", "100hp/10def");```
#

or perhaps i could make interface for the stat which takes base stat + all the stats from present items

#

that will work for adding and substracting, what with multiplying and dividing though?

#

i cant store that in int

rocky canyon
#

oh true.. use a scaling system lol

late burrow
#

how do i enter parameters for functions in different order?

#

they have setup default parameters so they not requirement

verbal dome
#

Maybe with MyMethod(secondArg: 123, firstArg: 321)

#

Not sure if it lets you do that

slender nymph

ok i forgot i add through function not constructor so it didnt highlighted

does anyone know why im gettin this error with this part of my code??

cosmic gorge
#

im kinda stupid lol

slender nymph
#

you probably want to compare either the magnitude of the vector or only one axis of it to an int since you cannot compare the entire vector2 to an int

cosmic gorge
# cosmic gorge sorry im trying to put my code 
// void inputManagement()
    {
        float moveX = Input.GetAxisRaw("Horizontal");
        float moveY = Input.GetAxisRaw("Vertical");

        moveDir = new Vector2(moveX, moveY).normalized;

        if(moveDir != 0)
        {
            lastHorizontalVector = moveDir.x;
        }

        if(moveDir != 0)
        {
            lastVerticalVector = moveDir.y;
        }
    }
#

there we go

#

that took an unnecessary amount of time to figure out

north kiln
#

you're comparing a vector to an int, do you want to check if it's magnitude is/isn't approximately 0?

cosmic gorge
north kiln
#

if (!Mathf.Approximately(moveDir.sqrMagnitude, 0))

cosmic gorge
#

wait

#

what

#

sorry im really new to this

north kiln
#

you can use .magnitude if you'd like

#

I say approximately 0, because floating point equality is inherently a dangerous thing. 0.000001 is not 0, so using equality is generally something you should avoid with floats

cosmic gorge
#

just looked up what magnitude is, sorry i'm not tying to find that

#

my bad

#

i'm just trying to make it to where my player faces left and right when a/d + w is pressed

#

i think

#

im following a tutorial and im trying really hard to intake information but its kinda difficult lol

slender nymph
#

so you probably want to compare the individual axes of the vector2 rather than its magnitude. that would make more sense considering you have two separate if statements

#

look more closely at what the tutorial has

cosmic gorge
slender nymph
#

although using Mathf.Approximately would be better than !=

north kiln
#

In the screenshot you can see it used .x and .y in the two if statements, unlike your code above

cosmic gorge
#

ok i fixed it

#

tysm lol

#

so i think i just need to pay attention better

#

im gonna rewatch that part and try and understand what the tutorial is saying when im done writing this script

north kiln
#

Imo if you're not understanding something then you shouldn't be copying it. Obviously you don't need to deep dive and understand everything, but at the very least it the concept needs to make sense in relation to the code you write

cosmic gorge
#

i know that != means not equal to, i know how to make if statements, and i know how to make functions

#

im just trying to understand the littler parts

north kiln
#

your original code asked:
(x, y) != 0
Which is the part you had to understand to reason what it should be doing instead

yes

wait

oh shoot, I just found out whats wrong

tiny wind
#

i was getting the transform component of the child object, not the parent's

#

ok sso new questiion, how do I get a component of another object to put in the code?

scarlet shuttle
tiny wind
#

Its part of the same prefab, could you please explain how?

scarlet shuttle
#

Define a public variable in the relevant script, it then appears in the inspector when you click the object that has that script attached

#

You can then drag the object/component/whatever type you want as long as it matches the type you defined in the script into that slot in the inspector

Hey everyone, got a small problem with ParticleSystem, when I was writing scripts:

So it says 1st one is depricated, so it's not recommended to use. So I tried to use with main, but it keep asking me for variable.

Is it okay to stay with 1st option for now because adding stuff like var main and etc. Is kinda out of beginnerc course?

IMG_20250118_173849_161.jpg
#

And how can I change the second option?

north kiln
tiny wind
tough plinth
#

Looking on that screenshot,
using ParticleSystem ps means telling code that ps means ParticleSystem?

And we use var to identify that main is a variable?

IMG_20250118_175527_678.jpg
#

Thanks in advance

tough tartan
#

Can u guys help me make it so when the enemy touches u, player loses 20 hp

#

This breaks all

#

the code aint workin

timber tide
#

but I can understand where they're coming from since dealing with the particle system is arse

#

The type is ParticleSystem.MainModule that you're getting back from it, but the dev typing the tutorial didn't want to type out the type so var is a shortcut. Basically you're saying hey compiler figure out the type for me thanks

north kiln
#

The C# convention is to use var when the type can be inferred from what's being assigned, so even in that context it has a place

spiral glen
#

If I were to make an upgrade system for something like a rogue like after you beat a level, should I seperate the gameplay and upgrade scene into two different scenes in unity or would it be better to just keep it all on one scene?

north kiln
#

But here it's not inferred so specify away!

#

Scenes just act as quick ways to bulk unload/load content. You can do it by destroying and instancing objects plainly too

#

Whatever works for you, basically

spiral glen
#

Which would be more simple for a beginner?

north kiln
#

A persistent management scene would enforce certain things that would avoid basic referencing mistakes in the short term

#

Neither is easier ultimately

spiral glen
#

I'll just try to use a different scene then

timber tide
#

If you're doing a level by level design it probably be easier to do multiple scenes

#

just because of the ability to deload everything

#

Otherwise you're making some management system that's to handle destroying each and one of those objects

spiral glen
#

I'm planning on making generated levels

#

then just replaying it with different enemies

#

and backgrounds etc

#

when i get to the art side of it

#

currently I'm just trying to plan out the upgrade scene itself

sterile path

so for the code

i originally referenced the 2 game objects and tried to enable and disable them through the event system in the XR event thing but couldn’t get anything to work, this is what chatgpt gave me :

    grabInteractable = GetComponent<XRGrabInteractable>();

    // Ensure the models are set correctly at the start
    closedBook.SetActive(true);
    openBook.SetActive(false);

private void Update()
{
    // Check if the trigger is pressed (while holding the object)
    if (grabInteractable.isSelected)
    {
        if (Input.GetButtonDown("Fire1")) // Change "Fire1" to the relevant input for the trigger
        {
            // Toggle the models based on the trigger press
            isOpen = !isOpen;

            // Enable/Disable models based on the current state

i’m new to all this so don’t mind me i’m a bit slow

then you should be paying more attention not less

there is your problem.
I told you to use the following
Book
Book Closed
Book Open

burnt vapor
#

Then share what you tried. People are more likely to help somebody who actually put effort into it

sterile path
languid spire
#

yes

sterile path
#

thanks i’ll try that

#

the script should go onto the main parent too, lemme fix all this

#

should both books have their own hit boxes, XR grab scrips or should the open book only have that since it’ll be the base

languid spire
#

all the stuff you need should be on Book. Book Open and Book Closed should just be the models

#

just shows you how bad GPT is. This

public GameObject closedBook; // Closed book model
    public GameObject openBook;   // Open book model

    private XRGrabInteractable grabInteractable;

makes no sense. why are 2 public and 1 private?

sterile path
#

Yeah i think i’ll write the code myself from now on, chapgpt never really got me anywhere and i don’t think it’ll ever get my anywhere

languid spire
sterile path
#

just a quick question, when accessing the trigger buttons for my controller, should i use an Ontrigger function or should i rely on the XR interaction’s event system thing

#

cuz those r the 2 ways i see it working but idk which is more reliable

languid spire
sterile path
#

oh alright

#

wait so how i see this is if it weren’t in VR and if i wanted to press a specific key for this to happen, it’d work like:

OnMouseDown()
closedBook.gameObject.Setactive(false)
and i’d do the same for the open but but set it to true

#

in vr i have to specify when it’s being grabbed, and i have to access the controller’s trigger, so im assuming thats the “Activated” event

#

i’m slowly figuring this out hold up

Hi
I'm trying to make these specific tiles act both as a Ground and Wall because I have specific animations for each state

private bool IsGrounded()
{
    RaycastHit2D raycastHit = Physics2D.BoxCast(boxCollider.bounds.center, boxCollider.bounds.size, 0, Vector2.down, 0.1f, groundLayer);
    return raycastHit.collider != null;
}
private bool OnWall()
{
    RaycastHit2D raycastHit = Physics2D.BoxCast(boxCollider.bounds.center, boxCollider.bounds.size, 0, new Vector2(transform.localScale.x, 0), 0.1f, wallLayer);
    return raycastHit.collider != null;
}

these are the codes I use to determine if its Grounded or Wall

#

Anyone know how I might be able to ndo that?

solemn wraith
#

Hey, I have this code: ```cs
Vector3 pointA = transform.position + givenVelocity;

but the issue with it is that pointA is calculated w givenVelocity in global space, but I really want to get the same output as `transform.Translate(givenVelocity)`
without moving the transform. Anyone know how?

1 question, what is that error... so i can ask in a certain channel

#

is it Unity related? or URP and Post-processing

languid spire

Thsts an internal Unity error, difficult to say where from without a stack trace

select the error and show the stack trace here

that is not the stack trace

what is stack trace

languid spire
#

the bit that appears at the bottom of the console window when you select an error

thats it

ok, so it says PostFX so it's going to be PostProcessing releated

When I use the code, instead of setting the rotation to the set values, it changes the value of several axes which is not what I want

All I want to do is for it to set the X rotation to 0, 90 and 180 for each option

With localRotation = for example

#

yeah i think so too

#

i dont really know about .Rotate but i did some research and it seemed funky

crisp eagle
obsidian plaza
#

i think its doing world space maybe

crimson fern
#

Yeah exactly

cosmic dagger
crimson fern
crisp eagle
#

ok it may be doing global, but then why does it change 2 axes when I clearly only change one of the axes? it goes like 0 0 0 to 0 0 90 and then suddenly 180 0 180 or smth

crisp eagle
obsidian plaza
crimson fern
#

No idea, I've only ever done this by the Euler angles

obsidian plaza
#

same

cosmic dagger
# crisp eagle

This looks correct. For case 1, log the localRotation before and after calling Rotate to see if the value changed correctly . . .

#

Also, you don't need to call Rotate for case 0 since it's not rotating at all . . .

I think I found the issue

#

I may have an extra chromosome ngl

obsidian plaza
#

were u rotating wrong axis

had a 90 degree rotation on the z axis which I was setting to 0 every time

Because I wanted to rotate along the X axis

I forgot I am zero-ing the Z axis too

code

obsidian plaza
#

try: transform.position += (Vector3.left * moveSpeed) * Time.deltaTime;

#

maybe thats the same thing

#

but it helps me brain

red mason
#

im also kinda confused cause pipe move isnt a game object in unity and i cant find it in pipe spawner or anything

#

so idk what its actually doing rn

ivory bobcat
#

Make sure to change the inspector values as the code were only the default values. The speed for instances do not change if they're created as prefabs or added to the scene already.

obsidian plaza
red mason
#

oh yeahh

#

pipe move is on the pipe prefavv

#

yep ty theyre faster when i change in unity

obsidian plaza
#

just cause y have it in code if u want to change in unity u know

red mason
#

ok tyty

obsidian plaza
#

because that way you don't need to go through your math and make sure ur doing PEMDAS correctly

#

glad its working though

ivory bobcat
#

You should actually multiply the floats together rather than each with the vector 3

red mason
#

yeah also do you need to save the script every time for unity to recognise it because every time i save it takes like 10 seconds to get ready then another 10 to actually run the game when i press run

obsidian plaza
red mason
#

ahk

obsidian plaza
ivory bobcat
obsidian plaza
#

ah ok

#

is it just slow

ivory bobcat
obsidian plaza
#

yea i saw that

ivory bobcat
#

A vector has 3 floats so each would do three times as computation and probably take up a bit more memory on the stack temporarily

obsidian plaza
#

gotchu

abstract copper
ivory bobcat
abstract copper
#

Like if its the position on screen or what

ivory bobcat
#

Why would you feed it to the camera function for converting from screen to world point then? Log it if you aren't sure.

#

If it's some normalized value.. then it's definitely incorrect

#

It needs to be the pointer position from screen space if you're to use the camera conversion function

Make VehicleLobbyUI an array or list

#

I assume that's what you mean

normal valve
#

I can't - It's a class of different objects. I assume it can't show nested class 😦

oh wait right it's not being instantied

#

what

#

ohh

#

you have it as a nested monobehaviour

#

remove that

#

er, but you have mono components on it ah nm it's just assets

normal valve
#

Ah that was the issue

This has nothing to do with object oriented programming really, it's a Unity thing

That doesn't make sense

#

You need an object to call methods on

#

Does the dummy already have the Enemy component on it?

fossil tree
#

yes and i try to make an object called trainingDummy

is Enemy a MonoBehaviour?

time to learn coding using learn.unity

anything that's a MonoBehaviour is managed by unity, so you shouldn't use new with it
you should instead tell unity to make it for you, with Instantiate or AddComponent

fossil tree
#

so i need to instanciate my dummy but how i make it an object of enemy ?

naive pawn
#

what defines an enemy object?

#

is it just any gameobject with an Enemy component?

fossil tree
#

he has hp and method

naive pawn
#

you can't make Enemy on its own
it's a component, it needs to live on a gameobject

warm field

#

you might want to make a prefab (or multiple prefabs, for multiple kinds of enemies) that has Enemy and then Instantiate that prefab

Hi! I'm messing with the Vector methods. This is my script that is responsible for rotating both my player on (y) and my player camera child object on (x). The angle datas I get from here.
My player turns to lookTarget just fine but my camera is turning up and away from the target. What am I doing wrong here?

@fossil tree what exactly are you trying to do?
are you trying to create a new kind of enemy?

fossil tree

#

i honestly have no idea what you mean by that

#

what do you mean by "gameobject script", or "object of enemy"?

cosmic quail
naive pawn
#

seems like you're confusing quite a few ideas here

fossil tree
#

ok wait a sec

#

i finish my game and send that
