I wouldn't be surprised if you couldn't reliably determine how to color those without parsing the entire script from start to end

#

for example, you couldn't tell Vector2.down (Vector2 is a type) apart from Vector2.down (Vector2 is a local variable)

languid spire
tulip stream
#

ok, i have another question

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

this time you can see i used a new vector for the direction, in this case i guess:

  • The box travels in the direction of whatever the transform.localScale.x is
  • And doesn't travel at all on the y axis because it's 0.
#

Correct me if i'm wrong.

slender nymph
#

yes, it will cast right or left depending on whether the x scale is positive or negative

tulip stream
#

and for the y axis?

#

i have it set to 0, but i believe it won't travel right?

swift crag
#

yes, because the Y component of the direction is zero.

ashen ferry
#

u can google a class.method and unity docs will be first result with good explanation ur current direction is pure left or right if u add some y then it will go up or down as well

tulip stream

thank you guys a lot

i'm just trying to acquire good fundamentals from the start of my journey in game dev

How do i fix this, i'm trying to make to set up sprinting in my game, but the "isSprinting" bool just flickers while "IsWalking" stays on even when Sprint is being pressed. ( I know how to fix the IsWalking problem). https://i.imgur.com/TzpwVlD.png

swift crag
#

why are you checking if the input was pressed on this frame?

#

don't you want to check if it's being pressed at all?

twin bolt
#

Isn't that how the new input system works, or am i missing something?

swift crag
#

it's how WasPressedThisFrame works, for sure..

#

you want IsPressed

twin bolt
#

oh wow, i didnt even know that was a thing

#

Wow that works, i previously used waspressedthisframe, in my old script, but i ended up having to recreate everything from scratch. Thanks

#

How do i fix a issue with my player controller, where when i crouch the player scales from the middle instead of bottom. I know i can just create a pivot, but that would completely mess up my player object. How can i scale from the bottom of the player using script?

You need to set up your Visual studios correctly, it will show you this

swift crag
#

Is your code editor highlighting errors right now?

twin bolt
#

!ide

royal linden
#

it says no errors

💡 IDE Configuration

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

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

• VS Code*
• JetBrains Rider
• Other/None

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

swift crag
#

then your code editor is not configured correctly

#

What code editor are you using?

royal linden
#

v studio

swift crag
#

Visual Studio, not Visual Studio Code?

swift crag
twin bolt
swift crag
#

although, you say "the player scales"

#

do you mean the CharacterController capsule?

twin bolt
#

Yea

royal linden
swift crag
#

Ah, then you just need to set its position correctly

swift crag
#

Show me a screenshot of your code editor.

swift crag
#

The controller is usually on the character root for me, so I can't exactly parent it to something else

royal linden
swift crag
#

That is Visual Studio Code.

swift crag
#

Do not skip any steps.

#

note that you will not be using the "Visual Studio Code Editor" package. You will be using the "Visual Studio Editor" package.

royal linden
#

breh

swift crag
#

If you can't update the "Visual Studio Editor" package to 2.0.20 or later, that's an easy fix. Ask me about if you can't.

royal linden
#

but it says this

image.png
swift crag
#

Yes. You are using Visual Studio Code.

swift crag
#

Both editors now use the same package: "Visual Studio Editor"

#

Follow the instructions to the letter.

royal linden
#

kk

#

where is Workloads tab

twin bolt
swift crag
#

if your only problem was that the character controller is in the wrong position, then you just need to set its offset...

swift crag
#

You have clicked a completely unrelated link.

#

Click the "VS Code" link. Follow the instructions.

#

You need to pay attention to what you're doing.

twin bolt
#

I'm using rigidbody, character controller was extremely janky for me when i used it.

swift crag
#

I'd move the colliders to child objects, then

twin bolt
#

No, sorry, i though your were referring my player controller

swift crag
#

the rigidbody can remain on the character root

#

(if this is not the setup, then I'll need to see what you're doing)

royal linden
swift crag
#

the "VS Code" link has zero mentions of "Workloads"

#

because "Workloads" are a Visual Studio concept

#

you are not using Visual Studio. you are using Visual Studio Code.

# royal linden im lost

this is complete nonsense. you have somehow installed and opened Visual Studio while allegedly following the instructions for setting up Visual Studio Code.

royal linden
#

but i installed from what it told me

swift crag
#

I told you repeatedly to click the "VS Code" link.

#

You have clicked something else and followed those instructions instead.

#

This is the link I've asked you to follow several times now.

#

Click it. Follow those instructions.

royal linden
swift crag
#

This has absolutely nothing to do with the instructions for VS Code.

royal linden
#

that was in the link

swift crag
#

What link?

royal linden
#

the bot link u put

swift crag
#

I told you to click the "VS Code" link in that message.

#

Four or five times now.

#

You are completely ignoring me. This is ridiculous.

royal linden
#

i did

twin bolt
#

This might actually be the longest it has taken someone to get the ide configured. I thought i was bad

swift crag
#

No, you clicked one of the two "Visual Studio" links.

i thought that was it

Why did you think the link that said "Visual Studio" was the link you should click when you were repeatedly told to click on the "VS Code" link

Is there a good way to tell what game object I'm hovering the mouse over? I'm debugging some drag-drop problems and I think there's an element on blocking my mouse but I don't know where to begin to get what game object it is

I'm also a beginner but I think I can help you out with this one.

The package manager can be found within the Unity Editor - the Unity Editor is what pops up after you've opened your project in the Unity Hub. After you've opened your project, you may need to open the "Project Manager" window from the "Window" tab in the menu toolbar at the top of your screen.

Hello guys,

Can someone help me understand Pixels Per Unit and Orthographic Size and Aspect Ratio?

  • I have an orthographic camera of size 6 at world origin
  • I have a gameobject with Sprite Renderer at world origin with scale (1,1,1)
  • I have a 1920x1080 .png file attached to this object
  • My aspect ratio is set to 16:9

I want my .png to fill the screen. How do I calculate the Pixels Per Unit when importing the Texture 2D asset?

1- Calculate the width of the camera view in world units:
Camera Width = Camera Size * Aspect Ratio = 6 * (16 / 9) = 10.67 units

2- Image width in world units should be equal to the camera width. So, PPU is:
PPU = Image Width / Camera Width = 1920 / 10.67 ≈ 180 PPU

But this is wrong. The answer is 90 PPU. But I don't understand why. Any help?

#

It perfectly fits if I set my PPU to 90 when importing... But I can't quite understand why

wintry quarry
#

Not the full height

#

So with size 6 it sees 12 units high

ashen ferry
#

I think u can just image Y pixels count / ortho size * 2 to get ur ppu? with same aspect ratio it will scale in automatically lol

wintry quarry
#

And 21.whatever wide

chilly jetty
#

so I have a problem with my game, so I Am making a character selector for my game which is like dani's game which is named off the balls but thats not important, anyways so when you choose a character and press spawn its fine since there is already a script to spawn the player/ball but on the GameManager it can only have one reference but i would have multiple characters so i use this approach
FindAndAssignBall();

private void FindAndAssignBall()
{
// Find the Ball component in the scene
ball = FindObjectOfType<Ball>();

    // Check if the Ball component was found
    if (ball == null)
    {
        Debug.LogError("Ball component not found in the scene.");
    }
}

but even tho there is a Ball component as i said the ball is spawned in im not sure if its because its happening in the same frame or not tho well anyways it won't get the component help!

north kiln
#

You should definitely not be using any Find method for this (or generally, ever, if you can avoid it).
When you spawn the ball, Instantiate returns a reference to it. So add that reference to a collection that associates it to a player. That list can be on GameManager if you want it to be

crisp radish
#

Thanks for the answers guys. PPU = Y pixels count / (ortho size * 2) it seems. Makes sense.

#

So, in my case PPU = 1080 / (6 * 2) = 90

chilly jetty
north kiln
#

That is not a helpful sentence. I cannot elaborate on a complete lack of understanding

chilly jetty
#

so this is the line of code i use to instantiate the player

#

Instantiate(GameManagers.instance.currentCharacter.prefab, transform.position, Quaternion.identity);

chilly jetty
north kiln
#

and Instantiate returns a reference to the spawned ball, so cache it in a collection like a list

chilly jetty
#

hello?

chilly jetty
north kiln
#

What part do you not understand? If I send you some code, I have no idea whether you'll even be able to understand it, or whether I'll just be thrown into elaborating something else

chilly jetty
north kiln
#

You Instantiate it when you need it, and you add the newly created instance to a collection like a list

#

then, you can easily find the object again by looking at the collection

analog lark
#

is Start() supposed to be called when an object just becomes active?

summer stump
#

So yeah, after the FIRST time it is active

#

And never again

#

If you're looking for something called whenever the object is activated, you want OnEnable

analog lark
#

no like i thought start() was called on all objects when the scene was loaded

#

not when something was enabled

#

(for the first time)

summer stump

If not active, it won't be called.

Does anyone know the website for learning the basics of programming?

Hey guys I have sort of a simple question

#

I have this script where I need to access a variable called "score" on another script

#

but the other script has several variables and I want to be able to set them on the inspector, what is the best way to do it?

#

for example, one of this script has scorer.score to take the value of the score variable, I want to have a field in the inspector to change this "score" to any variable I want to retrieve

summer stump
uncut pawn
#

yes, I want a inspector field where the string of the variable will replace the score variable in the code based on what the input is

#

Should I be using reflection or something?

summer stump
#

Yeah, it looks like you are wanting reflection

I would instead recommend that you simply call a method, and pass in a parameter to decide what to return. Maybe the parameter is an enum?

#

Reflection is costly and usually not the best solution, but that IS what you are asking for

uncut pawn
#

considering I have like one of this for each object on an inventory in the game, doesn't seems like the most optimized solution

summer stump
ivory bobcat
#

Why doesn't the other type expose it's members to the inspector?

uncut pawn
#

Integration between two assets that handle variables

ivory bobcat
#

Is this an Editor tool?

uncut pawn
#

I am tempted on doing it on an OnUpdate method or simply putting everything on the same script 😬

ivory bobcat
#

Else you can just reference the instances and assign it a value whenever - not specific to the Editor inspector.

uncut pawn
#

I probably can do it without reflection if I simply do it on a single script atwhatcost

#

probably is that the tool gave me an example on how to sync one variable when i will need to sync dozens

#

im making character selection stuff, but i have problem, when im creating object from prefab i cant save health bar value in prefab cuz its not character child object, then, is there any way to call object from hierarchy?

ivory bobcat
analog lark
#

should i call getcomponent in awake or start

ivory bobcat
uncut pawn
#

aaand. I did it with reflection

#

hope I doesn't tanks my performance when I have more than 100 variables to sync

ivory bobcat
#

I'd just reference the instances and modify the values where the instances are.

analog lark
#

is using rigidbody for platformer movement bad?

summer stump

summer stump
young warren
#

are you actually using TextMeshPro?

#

most likely you're using the UGUI version

#

never mind. show the component please

#

the one you're trying to get

#

yes, show the component

summer stump
#

if you have backgroundFrame, and title is the child, why use find?

young warren
#

please, show the component

#

the component that is attached to the Title object

#

the one you're trying to access with GetComponent

summer stump
#

In the inspector, which is by default on the right

young warren
#

yes

#

so, that TextMeshPro - Text

#

so the type isn't actually TextMeshPro, it's TextMeshProUGUI, but you can just use the parent class which is easier to type TMP_Text

#

so you want GetComponent<TMP_Text>

#

and if you havent learned what a component is, the beginner courses on Unity Learn will be beneficial

#

like the beginner scripting course perhaps

#

i hope you understand why it works

eternal needle
#

you should also 100% ditch this name based approach while you're at it, Intro can just have a script which holds these references then anything that wants to can interact with that object instead

#

its fragile when everything is supposed to be named a certain way or a random unrelated script breaks

final trellis

how would I specifically "target" the invItem that was found in the tempInvList List

I had a collision problem while using translate for movement because with translate I just phase through solid gameObjects so a member told me to switch to .velocity or .addforce or something so I want to know how i can edit my movement scripts to .velocity

eternal needle
#

if your character doesnt need to be tossed around, its probably better to use some custom character controller (like with kinematic rb)

polar comet
#

Well I think i should do that anyway because I think that would solve my collision problems

polar comet
keen dew
#

There are about a million tutorials for physics-based movement so maybe better to follow one of those

eternal needle
# polar comet I'm a bit lost can you explain that

theres just some annoyances with using physics to move, even though it solves the immediate collision issue. You should consider what your game is gonna be and how you're gonna let the character move. its hard to get right like how much to accelerate/decelerate by, friction is annoying, and collisions can result in unexpected movement

polar comet
#

Well I mean I think it might be the only thing I can do because collisions are worth the sacrifice

Howdy, I'm working on a Drag and Drop system. It works mostly as it should but the problem I have is when moving Items from slot to slot, specific positions with specific Items don't snap into the correct position. I'll showcase them starting in the Inventory, then moving them.

timber tide
#

Looks like you've a rogue slot there

#

have you debugged the positioning of where it's supposed to be socketed

dire ivy
#

I havent but I can give that a try

timber tide
#

Is there some invisible slots there

#

Can't tell the UI composition

dire ivy
#

I can tell you that the slots are a template made from a script that makes a grid. Its possible that what is the error is the actual slots themselves because you can pull the "slot" from the slot. I dont exactly know how to say it but these items are just changing the sprite

timber tide
#

yeah but like

#

is it a single layout element

dire ivy
#

oh yes

timber tide
#

vertical layout

#

Alright, so technically that whole layout there consists of slots but you've only got a portrait on some

#

sooo few things you can try to debug, assuming you're using Ipointer events. Name each slot and use IPointerEnter to debug.log the exact slot and see if the coordinates match

dire ivy
#

yes, i'm using the Ipointer events. I'll attempt to debug and get back to you

dire ivy
#

so with the provided image, interestingly enough the itemSlot position never changes with the 3 Items regardless of the position of the Item

image.png
#

I believe this has something to do with the original positioning of items vs the template being at 0, 0.

timber tide
#

What exactly is the full behavior of an item when you drop it into a slot? Is it being set to an index minus 1?

#

and have you confirmed that the slot your cursor goes over is the one displayed on the UI

If you mean method, say method. But yes, that's the one

queen adder
#

Make a text field where the user can enter a password.
User can access it? it's an editor script...

languid spire
#

you wanted to use it in the Inspector, no? That is the Editor

queen adder
#

yea the docs is quite confusing with the term user

#

since it's an editor, only use can see it, right?

#

actually imma just try to use it

swift crag
#

it's similar to GUILayout.PasswordField

#

EditorGUILayout methods include IMGUI logic that specifically works in the editor

#

This works just like GUILayout.PasswordField, but correctly responds to select all, etc. in the editor, and it can have an optional label in front.

#

I presume it's used by the VRChat SDK's login screen

for example

I'll just get to the point, im making a card game and when i draw a card i dont literally take the card i just recreate the card from the info that is in the deck abut some cards have different scripts and i dont know how to keep that info the same, can someone help?
here is the code

    {
        if(deck.Count >= 1)
        {

            card.GetComponent<Card>().handIndex = cardsInHand;
            card.GetComponent<Card>().suit = topCard.suit;
            card.GetComponent<Card>().rank = topCard.rank;
            card.GetComponent<Card>().faceCard = topCard.faceCard;

swift crag
#

you can just Instantiate an object to copy it

#

instead of instantiating newCard and then copying everything over

vocal marlin
#

this is because of pure laziness (because my dumbass made all the card scripts attached to a game object attached to a sprite renderer and normal transform instead of just an image and a rect transform which is what they need to be because they're in a grid layout group) but is there another way. its fine if not

cosmic dagger
vocal marlin
#

ill just be not lazy

#

and do it

#

ty for the help guys

cosmic dagger
#

and you can avoid the same GetComponent over and over . . .

swift crag
# 
Card cloned = Instantiate(topCard, cardHandArea);
cloned.handIndex = cardInHand;
#

you will probably need to fix its position and rotation afterwards

How to find B Vector, if i know only A Vector?

fossil drum
queen adder
#

Ok, so middle will be 0,0

#

can I make A * distance or something?

fossil drum
#

Well, then its quite easy, you can just normalize the A position, and multiply it with how far you want B to be.

#

Or don't normalize at all, and just multiply by something you want. But I guess the problem is bigger then this.

#

You could also use LerpUnclamped, from the origin and A, and then put in a value that's higher, depending on how far you want B to be from A. So lots of options UnityChanClever

Ok, for me first will be great 🙂

hey all, working on a topdown 2d TD concept to learn unity.
i've settled on making my player kinnematic type rb2d
while having enemies implemented as dynamic type rb2d
and mapobjects (trees/stones/etc) static type rb2d
does this seem like a right and/or typical approach?
making my player dynamic type rb2d produced frictions (when moving up against other mapobjects) that were not desirable for smooth movement, so for the player exclusively, I've opted for the kinematic movement.

verbal dome
#

Enemy as dynamic and map objects as static seems fine to me

queen adder
verbal dome
#

Yeah. Triggers are basically colliders that dont actually affect physics but can still detect hits

swift crag
#

object is keyword.

languid spire
#

no, for 2 reasons
Transform
object is a reservered word

swift crag
#

you will see an error like this if you try to use a keyword as a name

keywords have special meaning, so they are not valid names

Hey is there any issue with making a property that has a private getter and public setter

swift crag

It's weird, but as long as the compiler lets you do it...

queen adder
#

why its doesnt work

image.png
swift crag
#

I'd just copy the camera's Z-coordinate into the position

#

so

# 
Vector3 target = focus.position;
target.z = camera.position.z;
camera.position = target;
queen adder
#

about crosshair pos

swift crag
#

yeah, same difference

zenith cypress
# queen adder why its doesnt work

Well main thing I see is normalizedCrosshairPos seems unneeded, and it is getting a direction between a position, and a normalized direction. Wouldn't that just need to be

// get direction to new mouse position and scale it
var dragDirection = (dragPos - startDragPos).normalized * 5f;
// offset crosshair from player by scaled direction
crosshair.transform.position = (Vector2)player.transform.position + dragDirection;
queen adder
zenith cypress
#

Clarify? As I am not sure why you need that.

queen adder
#

With your solution works great, but Your solution make always like red cricle, but i need more distance like B circle

# 
void Drag()
    {
        dragPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        Vector2 dragDirection = (startDragPos - dragPos).normalized;
        crosshair.transform.position = (Vector2)player.transform.position + dragDirection;
    }
zenith cypress
#

If you want a bigger radius, multiply by a bigger value Hmmm

queen adder
#

and there is problem, because i dont know where put multiply

zenith cypress
#

.normalized gives a 1 radius circle. Multiply to make that circle whatever you want. *5f makes it 5 radius

queen adder
#

ok, everthing good

tender stag
#

i have to check here if the amount of the item you are trying to quick stack can fit into the cells

image.png
#

if it can fit, just Add to the cells

timber tide
#

if not do nothing

tender stag
#

and if it cant, make the cells item amount its max stack size

#

and subctract from the item you are quick stacking

timber tide
#

why does it fly out of your inventory

tender stag
#

because the Drop gets called

#

because the inventory cannot fit any more of the item

#

inside of it

#

so it drops the rest

timber tide
#

honestly you got a lot of the code going already and no one knows it better than you

#

if anything, yeah, you'll need a few more statements here so it stacks to the amount and after that do nothing

tender stag
timber tide
#

use as many statements as you want, nothing is intensive here

tender stag
#

i made comments if it makes it easier to understand

timber tide
#

you seem to have the idea there

tender stag
#

but im not sure how i can make it happen

timber tide
#

no item should be deleted or made, you're only distributing a number from one object to another

tender stag
#

what do you mean

timber tide
#

if the object can't fully fit, you're only adding onto an object until it's full. If you can't fully stack it then the original object stays too

tender stag
#

yeah

#

but if the item you are stacking can fully fit into cells

#

then you need to destroy it

timber tide
#

Yep

tender stag
#

and just add the whole amount of the item

#

i got the idea is im just confused

#

i dont want to make new functions for this

#

i want to keep the whole logic inside of HandleControlClick()

#

but i dont think thats possible

queen adder
#

hey all, in my topdown 2d concept, i have tree and stone prefabs, each with a animation controller.
when the player hits these objects with a pickaxe, the animation is triggered.
this works, but now I'm trying to enhance it so that the animation doesn't just always play the brief "up/down" bounce, rather bounces according to the direction of the hit. (which could be from any 360 position around the object). For example, if the player hits it from the left, instead of bouncing "up/down" it could bounce "left/right". how is this handled? i've tried a couple of things on the tree/map transform, the spriterenderer's transform, and the animator transform, but I'm not achieving the desired behavior.

swift crag
#

I see two options

#

One: Create animations for the four cardinal directions, then use a 2D blendtree to mix them.

#

Two: Do the movement entirely in code.

cinder shoal
#

Hey I've an issue with OverlapBox2D (collisions)

swift crag
#

If you did option one, you'd need to set two float parameters on the animator based on the direction of the hit

queen adder
# swift crag I see two options

thanks @swift crag , the animation is very simple, so I could see option 2 actually being a good possible fit. do you know which of the 2 is better for overall performance?

swift crag
#

If I did it in code, I'd probably do something like this

# 
private Vector2 basePosition;

private Vector2 offset;
private Vector2 offsetTarget;
private Vector2 offsetVelocity;

public void Hit(Vector2 dir) {
  offsetTarget += dir.normalized;
}

void Awake() {
  basePosition = transform.position;
}

void Update() {
  offsetTarget = Vector2.MoveTowards(offsetTarget, Vector2.zero, Time.deltaTime);
  offset = Vector2.SmoothDamp(offset, offsetTarget, ref offsetVelocity, 0.3f);

  transform.position = basePosition + offset;
}
#

It will be harder to get the exact style of movement you want.

cosmic dagger
swift crag
#

The blend tree approach would look more like

# 
public void Hit(Vector2 dir) {
  animator.SetFloat("hitX", dir.x);
  animator.SetFloat("hitY", dir.y);
  
  animator.SetTrigger("hit");
}
#

The animator would have a 2D blendtree state that's entered when the hit trigger is set. It would blend based on hitX and hitY

Hi, I have this struct:

[System.Serializable]
public struct PlaceableItem<T> where T : ItemSO
{
    public T ItemSO;
    public int MaxItems;
    [Tooltip("Amount the item should move for when switching planets")]
    public float HideOffset;
    [HideInInspector] public HashSet<GameObject> PlacedItems;
}

private void LoadPlanetItems()
{
    _loadedPlanet = GameManager.Instance.PlanetManagerScript.CurrentPlanet;
    foreach (var plant in _loadedPlanet.PlaceablePlants)
    {
        var np = Instantiate(_plantItemPrefab, _plantsMenu);
        np.Init(plant);
    }
}

public void Init(PlanetScript.PlaceableItem<ItemSO> plant)
{
    
}

I would like to pass a PlaceableItem<ItemSO> that was originally PlaceableItem<PlantSO>(which does derive from ItemSO) but I don't seem to be able to cast it or directly pass it to a function that accepts a PlaceableItem<ItemSO>.
The reason I am using generics in the first place is to make working with the inspector easier so I'd prefer to keep it that way.
Thanks in advance!

ty guys, works perfect now

umbral bough
# short hazel You would need to use *generic variance* to convert a generic type argument to a...

I see, gpt actually recommended the same/similar approach.
It however recommended an odd approach of casting which I haven't tested yet:

private PlanetScript.PlaceableItem<ItemSO> ConvertToItemSO(PlanetScript.PlaceableItem<ItemSO> input)
{
    return input; // This is essentially a no-op, but it satisfies the type system.
}

Is that a bad way of doing things because it seems like way less code tbh?

why doesnt it give me an error when checking for other layers im not touching like enemy or collider

slender nymph

because you didn't hit anything on that layer

raw valley
#

im probably missing something but i dont hit the item and it gives me an error but when i dont hit something else i dont get an error

slender nymph
#

your issue is literally that you are doing .gameObject on a null object. remove that part of the line and it will work just fine because collider can be implicitly cast to bool so the if statement will be checking if the collider is null. as it is now, you're trying to check if the gameObject is null but since the collider is null you are getting an exception

raw valley

oh i copied and pasted from the enemy collider and then changed it but forgot to change item collider im so stupid

mouseX = Input.GetAxis("Mouse X") * sensativity; mouseY = Input.GetAxis("Mouse Y") * -1 * sensativity; transform.localEulerAngles = new Vector3(mouseX, mouseY, 0);

#

the camera rotates for a frame then goes back to 0,0,0 instantly

swift crag
#

well, sure, you're setting the camera's rotation based on the mouse input from that frame

#

rather than adding to the camera's rotation based on the mouse input

#

I would suggest storing two floats for the X and Y rotations

#

add mouseX and mouseY to them each frame

#

then use them to compute the new local euler angles

#

(note that you'll probably want to switch mouseX and mouseY when setting the local euler angles)

#

moving the mouse horizontally should make you rotate around the Y axis

wooden minnow
swift crag
#

Quaternion.x is not the X-axis rotation

#

It is the X component of the quaternion.

#

You should generally never directly manipulate the quaternion's four values (x, y, z, w)

acoustic arch
#

i had to add it up

#

mouseX += Input.GetAxis("Mouse X") * sensativity;

swift crag
#

Also, manipulating the eulerAngles of a rotation is unreliable. For an example, try using the local rotation gizmos to rotate an object around one axis, then another

#

all three euler angle values can wind up changing

Hey, does anyone know how to make an object eraser/regulator? eg: there can't be more than 20 toilets, if that happens the toilets will be erased in the order of which one was generated first (I already asked this before but I can't figure it out and it wasn't so clear, sorry 😦 )

timber tide
#

that's a lot of toilets

ashen ferry
#

maybe make a queue where your toilets will be added when spawning them and if count is more than x dequeue one and destroy it

unreal imp
#

what the queue will do is that if the toilet number 1 that has place 0 in the array is destroyed, it assigns the second toilet to place 0 of the array, then with the third, fourth,etc to be the cuantity equal to the limit?

ashen ferry
#

its like a supermarket queue when one customer leaves everyone behind it takes step forward lol

short hazel
#

It's literally like a queue of people waiting to do something. The people arrive at the end of the queue always, and the first one are picked out always
FIFO collection: first in, first out

#

Queue<T> type, in System.Collections.Generic

swift crag
#

Yeah, a queue is precisely what you want.

#

One thing to note. If you destroy an object, it will not leave the queue.

#

So you might erroneously think you're out of space

#

Queue<T> does not allow you to access random items

#

So, even though it's probably slower, it might make more sense to just use a List<T>

#

you'd then need to make sure you clean the list frequently enough

#

maybe every time the list is full and you're thinking of destroying an old item?

timber tide
#

Honestly, just do an array if you know the exact indices that you want ;)

swift crag
#

then you'd have to move items around manually when removing them

ashen ferry
#

Gameobject oldToilet = toiletsQueue.Dequeue(); it will dequeue and u got ref bro wont even stumble upon Peek(); at first to leave it in queue kekW

timber tide
#

Guess it depends on usecase, since having an empty index in between may be wanted?

wouldnt you do a stack now for that haha

actually even typed out list doesnt create new entries with elements already created lol

its scriptable object I want it to be like an asset to look at for values for that planet I cant loop through in declaration

actually I think it aint even possible im gonna make it from scratch in editor for each planet M_deadinside

timber tide
#

If you just want to see the values you could just do like some readonly list perhaps?

#

and populate it within onvalidate

#

otherwise to make a new enum type I'd assume some parsing

ashen ferry

yea that woulda worked prolly but already made the lists by hand so no going back sadok

analog lark
#

is it fine to use playerprefs to store which levels a player has completed?

summer stump
#

Something like gameplay data, I wouldn't use player prefs

analog lark
#

what should i use instead?

#

a static class or smth?
or a singleton gamemanager

ashen ferry
#

just do json prolly

summer stump
#

But you should have an object to hold the data when you retrieve it, like a singleton, as you said.

But that alone won't do the job, because when yoy close the game, the data the gamemanager holds will be lost unless writing to a file

swift crag
#

You might hold the data in a singleton

So I'm trying to create a bullet that homes towards the player, but, I don't want it to excede a maximum turn angle. I think I'm doing something wrong here, and, I'm not 100% sure what I'm doing wrong...

void FixedUpdate() {
        if (!hasStartedMoving) return;
        if (Mathf.Abs(currentMax) >= maxTurnAngle) return;
        Vector3 directionToPlayer = (player.position - transform.position).normalized;
        Quaternion rotationToPlayer = Quaternion.LookRotation(directionToPlayer, Vector3.up);

        Quaternion newRotation = Quaternion.Slerp(transform.localRotation, rotationToPlayer, homingSpeed * Time.fixedDeltaTime);

        float angleDiff = Mathf.DeltaAngle(transform.localRotation.eulerAngles.y, newRotation.eulerAngles.y);
        if (Mathf.Abs(currentMax + angleDiff) <= maxTurnAngle) {
            currentMax += angleDiff;
            bgBullet.SetRotation(newRotation.eulerAngles.y);
        }
    }

#

if I want to generate random int never repeated prior I suppose theres only way about it have a list of generated ints and check if new one isnt in that list?

slender nymph
#

yeah pretty much, though i'd recommend a hashset instead of a list. unless you have a predefined range that isn't large in which case an array would be pretty simple to use

#

HashSet will be easiest to use and one of the quicker options since it has an O(1) lookup time

ashen ferry
#

cool thx

lone sable
#

It almost sounds like you might be trying to do a GrabBag style randomization? If thats the case, I'd copy one list to a new list, then whenever you randomly pull from the "GrabBag", remove it from the list. Once the count reaches zero, re-add and repeat.

ashen ferry
#

nah its identifier thing huge random int would pass its function more clearly since its created together with planet and never edited or looked at by human again but im just obsessed with random stuff and prolly gonna do same like before, start at 0 and go up by one after each planet lol way easier to store/use

slender nymph
#

if you don't mind the identifier being 128bit instead of 32bit you could use a Guid instead. then you won't have to worry so much about tracking what has been used since it is very unlikely to get collisions

hidden citrus
#

is it possible to execute code on an entire list all at once, or is an iterator like for/foreach required? I want to execute minions[i].Kill() on every single minion, problem is each minion has an Ondeath event which auto removes it from the list, so the code breaks because the list shrinks dynamically, and it'd be iterating over nulls/missing/shrunken count which results in everything falling apart. It'll iterate 1-2 entries then break because the total count is reduced each kill() thats executed

modest dust
#

Or iterate starting from the last one

#

Then the decreasing list length won't matter

hidden citrus
#

ah good point, like a secondary list/array. that would solve it id imagine. thanks

It might be easiest to implement an attack as a coroutine

Has anyone ever seen this? The enemy is showing a super small X velocity but when I log it to the console, it shows 3. I have no idea what is causing this or how I would fix it.

# swift crag It might look like this 

// this would get called by an animation event
void PromptReady() {
  ready = true;
}

IEnumerator Attack() {
  animator.Play("Run");
  
  while (!reachedTarget) {
    // some logic to move the player goes here.
    // reachedTarget becomes true when you get close enough.
    yield return null;
  }

  ShowButtonPrompt();

  ready = false;
  hit = false;
  bonusDamage = false;
  animator.Play("Jump");
  
  // hit gets set to true when you actually hit the enemy.
  // this could be an animation event, or it could be distance based. whatever works.
  while (!hit) {
    // some logic to make the player move through the air
    if (Input.GetKeyDown(KeyCode.Space) && ready)
      bonusDamage = true;
  }
  
  if (bonusDamage)
     enemy.TakeDamage(3);
  else
     enemy.TakeDamage(2);

super rough idea

#

The jump animation would trigger the PromptReady animation event

Where do you actually call HandleAllMovement. Also, slerp is used incorrectly there. It needs to increase from 0 to 1, but you are doing a set value multiplied by deltaTime (which is a value that goes up and down or stays the same).

hallo, Im working on an inventory system, and Ive come to the point where I need to decide on a more "formal" structure. I've heard a lot of good reasons to use item ID's, but I'm not sure how I would integrate that while having items with "dynamic properties". Would it make sense to create a whole system for creating item ID's or would just adding their classes to a list be just as effective?

queen adder

# queen adder ill just remove the line of slerp?

For now, I would comment it out. We want to reduce factors in the issue. Set the rotation directly to targetRotation to see what that changes.

Slerp will need to be fixed to use it. It isn't smoothly increasing from 0 to 1, it is jiggling around some value based on your framerate

                transform.rotation = Quaternion.Slerp(currentRotation, targetRotation, rotationFactorPerFrame * Time.deltaTime);

why does it not work correctly in isometry?
if I press W then the character goes to the left
I have to press W+D to make it go up
currentMovement.x = currentMovementInput.y; work W and S

@weak talon you should store the coroutine in a variable and check if that variable is null before starting the coroutine, then we can see if it works. you may have overlap from calling the same coroutine multiple times when the mouse button is let go . . .
