did you perhaps make the rigidbody Kinematic? or are there perhaps colliders or friction preventing the object from moving? and have you verified that Acceleration is not 0?

#

collection initializer syntax

rich adder
#

use the {}

rotund hull
#

where would i use {}

yo boxfriend, you want the smoke?

slender nymph
#

you can take your shitposting somewhere else. i told you what you need to use, so put literally any amount of effort in by googling it

The debug prints values but the car still wont move

rich adder
#

don't need to crop show it selected in the scene

zealous junco
rich adder
#

make sure forward is not like down or some shit lol

#

might be too much mass and too low acceleration / force

zealous junco
#

Forward stays ths same in local

slender nymph
#

also make sure that your acceleration is high enough to overcome friction

rich adder
#

ya crank that

// If the inventory this cell is has a weight limit and can still fit something in

{
    Debug.Log("Item Amount: " + item.amount);
    Debug.Log("Item Weight: " + item.itemData.weight * item.amount);
    Debug.Log("Max Inventory Weight: " + cell.inventory.maxWeight);
    Debug.Log("Inventory Weight After Adding: " + (cell.inventory.currentWeight + (item.itemData.weight * item.amount)));

    // The current weight is above the max weight or if this item was added it would exceed the limit
    if(cell.inventory.currentWeight > cell.inventory.maxWeight || (cell.inventory.currentWeight + (item.itemData.weight * item.amount)) > cell.inventory.maxWeight)
    {
        Debug.Log("No i don't feel like working today");

        return false;
    }
}```
#

this literally makes no sense

#

it literally checks if its above

#

and somehow its still false

#

even tho currentWeight isnt above maxWeight

slender nymph
#

you should format those numbers to include more digits because i bet it is above maxWeight due to floating point imprecision or something

tender stag
#

floating point imprecision?

#

looks fine to me

vestal wasp
#

Does anyone know a playlist that will help me make a gacha game

slender nymph
# tender stag looks fine to me

in that case format your code better so you don't have giant strings of calculations being repeated by utilizing local variables, it will also make debugging easier.

I saw one on it but I think the creator deleted it

#

if the item.amount is more than 1

#

if its 1 then it works fine

slender nymph
#

mate, your code is practically unreadable because of the amount of objects you are accessing per line. if you don't want to format your code to actually be readable then i won't help you

#

it's literally as simple as just using some local variables. var newTotal = cell.inventory.currentWeight + (item.itemData.weight * item.amount); then you just use newTotal in place of all of the instances where you are doing that calculation again

tender stag
#

i know but i only started working on this a few minutes ago

#

so i couldnt be asked

#

i do that at the end

#

i'll change it hold on

tender stag
# slender nymph mate, your code is practically unreadable because of the amount of objects you a... 
// If this cell uses a specific inventory and has a weight limit set
if(cell.inventory != null && cell.inventory.maxWeight != 0)
{
    var inventory = cell.inventory;
    var itemWeight = item.itemData.weight * item.amount;

    // The current weight is already above its max weight or if you added the item weight to the current weight and it would be bigger than the max weight
    if(inventory.currentWeight > inventory.maxWeight || (inventory.currentWeight + itemWeight) > inventory.maxWeight)
    {
        return false;
    }
}```
#

that should be more readable

#

the first if check isnt the issue

#

its the second one

#

i just added this debug

#

let me check

#

what

slender nymph
#

once again you are copy/pasting calculations because you didn't bother putting them into local variables. do that and then you can easily print all of the relevant values at the same time

sharp abyss
tender stag
#

my what

sharp abyss
#

maxweight

slender nymph
#

for example, if you stored inventory.currentWeight + itemWeight in a variable called newWeight you could print this: Debug.Log($"Current Weight: {inventory.currentWeight}, Max Weight {inventory.maxWeight}, add item with weight {itemWeight} would be {newWeight}.");

north kiln
#

If you're having this much trouble just logging out variables use the debugger and just inspect the variables and outcomes directly

sharp abyss
#

-9 isnt a strange outcome. I dont know how much you added but we checked if currentWeight is bigger than max so it should be in -'s

tender stag
#

alright

#

explain to me

#

difference between these two

#

because the top one works

#

even this works

#

its this bit (cell.inventory.currentWeight + itemWeight)

sharp abyss
# tender stag

why did you add item.itemData.Weight * itemAmount to current weight? doesnt it already have them

tender stag
#

for each item u add weight

tender stag
#

its the same thing, i wrapped it in the brackets

slender nymph
#

you have an error in the console that you are ignoring

sharp abyss
slender nymph
#

because i know how loops work lmao

tender stag
slender nymph
#

possibly 🤷‍♂️ inspect the actual values using the debugger to find out

tender stag
#

i mean it works

sharp abyss

tender stag
#

u can drag multiple items into cells

glad comet
#

why is this an infinite loop?

frosty hound
#

Beacuse you have no way for your while loop to end?

#

So it's infinitely running in a single frame, not allowing your game to progress.

#

Does your log actually print though?

glad comet
#

no

frosty hound
#

If you comment it out, does it still freeze?

glad comet
#

when i ran it the code just kept running without being able to stop it

glad comet
frosty hound
#

The loop, if you remove it, does your game still freeze?

glad comet
#

no it works fine if i remove it

#

i thought that the while loop would end after runningTotal got bigger than whatever maximum i put in the condition

frosty hound
#

Yes, in theory that should work

#

But also not needed. It'll run in a single frame, you could essentially set the value manually and it'll do the same thing.

glad comet
#

im looking to get a series of numbers using the calulation for runningTotal

#

now that im thinking about it a for loop would work better but I want to understand why this loop didnt work

#

why is it an infinate loop

#

just got it working

#

the problem was I was using '=' instead of "+="

#

thank you

frosty hound

Ah yes, sorry, I'm playing games so I was skimming the code

I've got a bunch of ui elements on my screenspace-camera canvas

Screenshot_642.png
#

and I want to connect all of them up with line renderers

#

but I'm getting stuck on how to turn their position into something usable for a line renderer

grand badger
grand badger
grave bluff
#

interesting

#

straight up UI_element.transform.position can be thrown into the line renderer and it just works? kinda crazy

grand badger
#

Or maybe you need to do Camera.main.ScreenToWorldPoint lol.

grave bluff
#

ok both transform.position and screentoworldpoint give me craaaazy numbers that don't match up with anything

#

ui position is tricky stuff

#

yeah doing transform.position on these things is not doing me so hot

deft grail
grave bluff
#

the issue I'm having is incredibly weird. after a lil investigation it kinda looks like the transform.position of the ui elements is incorrect for the first frame and then correct afterward

#

I have a debug.log in update() writing down the transform.position of one particular ui element.

for whatever reason, the first 2 frames has an incorrect position, but then the third frame and then on is correct

Screenshot_643.png
#

which is even weirder given that there is zero other code anywhere that moves the UI elements after start(), yet they're moving during update() before resting to their final position

Can anyone help me figure out why nothing is outputted to my Debug Log here:

thanks

deft grail
glad comet
#

thank you

#

i still cant get the middle chunk of errors though

#

all on that "randomPositon" line

deft grail
#

not when intializing the variable

#

make a new method SetRandomPosition() or something, or do it in Start if you do it just once

glad comet
#

I keep making that mistake. Let me see if I can solve the last few errors.

grave bluff
olive beacon
grave bluff
#

I think it's a little weird how offset the ui update is, to the point that it takes 2 whole frames of waiting to get the real new position

#

but whatever, I have a working thingy now.

#

I've spent 90 minutes on something I thought was gonna take 15

olive beacon
#

and a working thingy is all we need

grave bluff
#

it turns out transform.position on a ui element IS the correct world position

#

no rect handling needed

glad comet
#

how do I get my code to ask for a rigidbody2d that I can drag and drop into the script component in the editor?

deft grail
#

or you can do [SerializeField] private instead of public

glad comet
#

i think im doing this but its still not asking for the rigidbody

#

im sending the code

deft grail
glad comet
deft grail
glad comet
deft grail
#

do you have any errors in the console

glad comet
#

yes

deft grail
#

only one error that says that im not referencing rigidbody

deft grail
#

otherwise scripts cant compile

#

what error

glad comet
#

Assets\ballScript.cs(7,12): error CS0246: The type or namespace name 'RigidBody2D' could not be found (are you missing a using directive or an assembly reference?)

I keep getting the an error that says that "randomPosition" doesnt exist in the current context on line 23

how do i call the randomPosition variable correctly

cinder schooner
#

i think on line 14 you are caching a new local variable instead of assigning it to the defined field at the top line 11

#

if you remove Vector3 from line 14 and assign the random position directly, it should work.

thank you

i tried to make a 2d movement in right and left direction with the new unity input system. the keybind are wasd. i noticed that everytime i move and pressed w / d, my movement are slower because the value got split in half. ( example : normal value 1, becomes 0.71 ). it becomes slower because i multiply it by player speed. Can someone help me to make value doesnt get split in half?

Normal Vector2 value condition : Move Value = (0.00, 1.00)
Half Vector2 value condition : Move Value = (-0.71, 0.71)

public void OnMovementInput(InputAction.CallbackContext context){
        MoveValue = context.ReadValue<Vector2>();

        Debug.Log("Move Value = " + MoveValue);
    }

Don't normalize it.

i dont

ivory bobcat
#

What's the issue then?

#

I'm assuming you're working with the raw values now or something. Not a whole lot of info was shown.

solar arrow
# ivory bobcat What's the issue then?

i wanted to make the movement speed the same even when player pressed up / down keybind. and what's make my movement speed slower is because when ReadValue notice of 2 direction input. they will split half the value, idk why and thats what i want to fix

languid spire
#

the normalize was what was causing the 1 to become 0.71 so where is the problem now?

solar arrow
ivory bobcat
#

Half would be 0.5

#

If you want the values to be one or zero: divide by the value and multiply by one - cast to int if you aren't wanting floating point values ect or some math function (divide by zero warning)

solar arrow
#

so its the ReadValue that normalize it?

#

its a function inside of unity

ivory bobcat
#

Or round round up to one etc

#

Check the mathf class for Unity

that does not explain why there are 4 of them in Update

eager spindle
fading vigil
#

just character controller

languid spire
#

if you have CharacterController why use transform.position?

eager spindle
#

I'm pretty sure that there's code in PlayerCode that could be teleporting you back.

But more to the point, do cache the reference to PlayerCode rather than calling getcomponent so frequently.

#

It's possible that you teleported into a wall, and because charactercontroller doesn't know where to bring you to, so it teleports you back to your last position instead

fading vigil
eager spindle
#

Does PlayerCode inherit from CharacterController?

fading vigil
eager spindle
#

do you know what inheritance means

fading vigil
#

or am I wrong?

eager spindle
#

In your code you see something like public class PlayerRayCast : Monobehaviour, PlayerRayCast inherits from Monobehaviour

#

What does PlayerCode inherit from?

fading vigil
#

MonoBehaviour

#

In that case you should be disabling CharacterController

[RequireComponent(typeof(CharacterController))]
Also there's this

Not PlayerCode

#

it not really a lag freeze, just that I cant click anything/the UI doesn't update

you can't say "freeze" when you mean "everything still works except for UI"

Is anyone able to help me please. I have visual studio installed, I have the unity tools installed. I have created a script in unity, automatically opened it in Visual Studio. I don't get any syntax highlighting. I have gone to edit, preferences, external tools, regenerate project files, then reopened visual studio script, still no syntax highlighting. I am using unity 2022 v3.48f1 , and Visual Studio 2022

this shows that something you have selected is not installed, are you sure you've installed the game development with unity workload already?

mellow rose
#

I mean, I'm not sure I can make the tick next to the Game development with Unity any more... tickier :p

slender nymph
#

just ticking the box doesn't install it. you have to actually click the install button

mellow rose
#

Yes 😛

#

(I'm aware)

slender nymph

okay well again, something you have ticked is not installed which is why i brought this up

what version of the visual studio editor package do you have installed in unity

mellow rose
slender nymph
#

that does not answer the question i asked

mellow rose
slender nymph
#

and you have completely closed visual studio and restarted it after having regenerated project files?

mellow rose
#

I've closed visual studio, regenerated project files, reopened, deleted the scripts, closed visual studio and unity, reopened unity, regenerated the script again, reopened visual studio. closed it again, checked that the Unity workload is 'really' installed... 🥲

slender nymph
#

right click the project in visual studio and select Reload With Dependencies

that worked. 👍

thanks

toxic void
#

Hey, why does my array not have a sort method, is it because it's not an array of a primitive? If so how can I sort it manually?

image.png
#

I want to sort it by smallest sqrMagnitude to biggest sqrMagnitude

keen dew
#

Array sort is a static method for the Array object. Array.Sort(positionArray, ...)

toxic void
#

oh, thank you

keen dew
#

If you use LINQ it'll add methods to arrays

toxic void
#

Another question, is the Icomparer just the value which the method sorts by?

#

or does it do it automatically by the magnitude when taking a Vector3

keen dew
#

I don't know if Vector3 has a default comparer implemented. You probably need to pass in your own

Hey guys, I have a question, I'm trying to instance a sprite of a square in the start, but the editor freezes at the moment I start the game, i'm doing something wrong?

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

public class RenderBoard : MonoBehaviour
{

    private GameObject square;
    // Start is called before the first frame update
    void Awake(){
        square = GameObject.FindWithTag("Square");
        //for(int i = 0; i< 10; i++){
            for(int j = 0; j<20; j++){
                Instantiate(square, new Vector2(2f, (float)j), Quaternion.identity);
            }
        //}
    }
    void Start()
    {
        
    }
    // Update is called once per frame
    void Update()
    {
        
    }
}

(I only have the square in game)

ivory bobcat
wraith hill

#

Your component script

#

If square has a render board, the Unity Editor will crash on attempting to play

wraith hill
#

aaah

#

i get it

#

wait

wraith hill
ivory bobcat
#

Right, so you'll make infinitely many squares

#

Thus you'll freeze the editor

wraith hill
#

aaaah I get it, thanks, so maybe move the script to the game manager, right?

hello,
volume slider doesn't attach with this code. do I also have to connect it inside the engine?

   }

   public void changeVolume(float volume)

okay now show what i asked for

burnt skiff
#

which one is that

slender nymph
burnt skiff
#

ohhh alright

slender nymph
latent ore
slender nymph
#

assuming that you have actually called the method that adds the listener, and that the volumeSlider and musicBackground variables are assigned

latent ore
slender nymph
#

show it

latent ore
# 
   public void StartGame(int difficulty)
   {
       isGameActive = true;
       musicBackground = GetComponent<AudioSource>();
       Music();
       spawnRate /= difficulty;
       StartCoroutine("SpawnTarget");
       score = 0;
       currentLives = maxLives;
       LivesText.text = "Lives: " + currentLives;
       UpdateScore(0);
       titleScreen.gameObject.SetActive(false);



   }
slender nymph
#

and where do you call StartGame?

latent ore
#

somewhere close to the bottom

#

its organized alphabetically

slender nymph
#

wdym? i'm asking where it is called not where you've placed that method in the class. just show the full code

latent ore
#

im not calling it anywhere, its the same as start

#

should I call music() in update?

slender nymph
#

it's not the same as Start . . .

languid spire
#

why would you think Start() and StartGame() are the same thing?

latent ore
#

oh yes you're right sorry i mixed it up with update

#

startgame is called in start lol

ivory bobcat
slender nymph
#

and you have confirmed that is actually being called

latent ore
# 
public class Difficulty : MonoBehaviour

{
    private GameManager gameManager;
    public int difficulty;

    private Button button;
    // Start is called before the first frame update
    void Start()
    {
        gameManager = GameObject.Find("Game Manager").GetComponent<GameManager>();
        button = GetComponent<Button>();
        button.onClick.AddListener(SetDifficulty);
    }



    void SetDifficulty()
    {
        Debug.Log(gameObject.name + " was clicked");
        gameManager.StartGame(difficulty);
        gameManager.isDead = false;

        Debug.Log("is player dead?" + gameManager.isDead);

    }
}
#

i mean the game plays so....

#

theres no errors

verbal dome
latent ore
#

figured it out

#

had to call it in update

    }
}
deft grail
#

but thats how you would take damage yeah

pastel sleet
#

I have put them back

rocky canyon
#

checking tag first and then grabbing for DamageSystem is better. b/c the way u have it now it'd try to grab the component from everything

#

vs just the things u know will have that component

wraith hill
#

hey guys, any idea why this happen? I instantiated the square several times as a prefab to form the rows and columns, but some lines don't render coorectly

pastel sleet
pastel sleet
ivory bobcat
#

TryGetComponent and simply damage whatever's hit, unless there isn't friendly fire. Could probably filter relative to layer as well though using the physics matrix

rocky canyon
# pastel sleet Sorry what?

without the tag check
it will run GetComponent on everything it happens to Collide with (enter the trigger).. i was just simply saying its better to have that initial tag check first.. so u can limit what its being called on (by using a tag you can check the objects you already know will have the Component ur lookin for

Shouldn't Facing.Player bleed into Facing.Random when the if statement is false? case Facing.Player: if (Random.Range(0, 1f) < chanceOfFacingPlayer) { controller.FacePlayer(); return StatusMessage.Completed; } case Facing.Random:

wintry quarry
#

Yes

#

It will

blissful yew
#

It complains and says a break statement is missing

wintry quarry
wintry quarry
blissful yew
#

it's highlighting the }

short hazel
#

It will error as your case has stuff in it

You need a break on the final case

#

Oh yeah maybe you can't drop through with code in the case

tight cradle
#

could I dm you?

wintry quarry
#

No

blissful yew
wintry quarry
#

Explain your actual issue

#

Explain what particularly isn't working and how

#

"scripts don't work" is too vague

short hazel
#

Case fall-through will only happen if you have something like

case A:
case B:
  // stuff

It's in Java that fall-through is unresricted, IIRC

blissful yew

#

Add goto case Facing.Random; at the end to force fallthrough

#

Nice!!

#

I knew there was a way to do that

I got this error

bool a = true;

//B is now true IDK why but if a is and stays true, why does it still go into this if statement and turns b true?
tight cradle
short hazel
#

Assuming this is all in the same method

spring skiff
#

This here is a simple showoff but I can record a video in the VS Debug mode, how it jsut dont care and turn my variable still true

short hazel
#

The debugger lets you hover over the variables to check their values, try to use that.

spring skiff
short hazel
#

Make sure you saved the code and returned to Unity for it to recompile. Make sure you were not in play mode while doing all that

spring skiff
#

OK I guess I found it but it was something with colliders and NPC FOV. The Player closed the Locker and the NPC cant see him anymore because of the doors. I hope I can make the doors still somehow not seethrough, but seethrough for the NPC so that the player cant hide in this locker while he is in the FOV of the NPC. In my case, the doors closed and blocked the rays of the NPC eyes

why would anyone use GetButtonDown() over GetKeyDown()? I understand not using the new input system cause of its complexity, but GetButtonDown() uses strings as opposed to the much better keycodes of GetKeyDown(), no?

GetButtonDown is useful if you've set up a specific button configuration in the input manager settings

trying to make a bullet destroy an enemy and i made sure via tags the enemy will be destroyed but for some reason it just goes past

How can i Normalize this? When pressing W and D for example, the magnitude is 1.4, however i want the magnitude of the Vectors to always be 1

Construct one vector, normalise it at the end, then multiply by Delta time

#

Also, consider using input axes (or the new input system) instead of querying for individual keys

So i think the issue i am having is the bullet not spawning in properly and it leads to it spawning where the original object was

ok it says it could be due to corrupt file or anti virus
turn off your anti virus and re install Unity, or just re install Unity normally

did you reinstall editor through unity hub? you gotta do that

Offline installation? That could potentially be the cause of the issue.

in the hub to to installs, and click install editor

then click the version you want

# teal viper Misconfigured !ide

Just a quick followup, turns out the Visual Studio Editor package for this specific Unity project wasn't installed for some reason, assumed it just came with it so of course installing that did the trick

teal viper

Perhaps upgraded from an older editor version?

rancid tinsel
#

is there a way to check if a variable exists on a scriptable object?

#

before trying to do anything with a variable that might not exist i mean

cosmic dagger
arctic ridge
#

Using a script, im trying to rotate an empty parent object, so that the children rotate with it. However, the children do not seem to rotate with the parent. Is there any reason why? Let me know if the code is needed

teal viper
#

And how are you gonna do something with a variable that you don't know exists or not.

teal viper
arctic ridge
#

Ill check real quick, totally possible

#

Yup! I assume it should be static then?

teal viper
#

It should be kinematic.

#

Though, I'd assume there is a reason why it's dynamic, and making it kinematic would break something else in your setup.

arctic ridge
#

I dont think it will, i dont have any script moving the children specifically

#

It works now, thank you so much!

rancid tinsel
#

turns out i had to cast it i think it was called

#

like this

image.png
teal viper
rancid tinsel
#

im sure there is a better way of going about it but im just rushing through this task

teal viper
#

Just declare it as WeaponScriptableObject.

rancid tinsel
#

but what if i want to use a GenericScriptableObject later in the else statement

teal viper
rancid tinsel
#

and make the ....ScriptableObjects inherit from it?

teal viper
#

No. Make the base class inherit from ScriptableObject.

rancid tinsel
#

pickupscript?

teal viper
#

Item : ScriptableObject
WeaponItem : Item
Etc...

rancid tinsel
#

ah yeah i see what you mean

grand badger
#

if (heldItem is WeaponItem weapon) { sr.sprite = weapon.sprite; }

rancid tinsel
#

is this what you were talking about dlich or did i do it wrong?

image.png
#

im guessing ill have to change the script name too if im doing it like this

grand badger
#

It’s correct, but each SO type needs to be on its own script yes

rancid tinsel
teal viper
#

I think it's fine in the latest versions of the editor, but I'd still put them in separate files.

grand badger
#

Maybe that’s changed on recent unity versions. Try it

rancid tinsel
#

im probably wrong but does this then kind of work like polymorphism where if i try to access the weaponType, it will know which SO its meant to be?

#

not polymorphism

#

bruh, inheritance

grand badger
#

No, it’s polymorphism

#

Yes

rancid tinsel
#

im too tired lol

grand badger
#

Inheritance is a feature that allows devs to use polymorphism

rancid tinsel
#

im learning them both rn at uni and im getting the terms slightly jumbled together

#

do you mean that inheritance comes with a form of polymorphism built in?

grand badger
#

Which allows you to reference inheriting types as types of smaller depth

#

Polymorphism is when you assign apple to var of type fruit

#

Inheritance is when you inherit fruit from apple

teal viper
grand badger
#

Polymorphism wouldn’t work if inheritance didn’t exist

rancid tinsel
rancid tinsel
#

like Attack() and Attack(bool ranged)

grand badger
#

That’s not polymorphism lol, that’s called method overloading

rancid tinsel
#

is that not part of it?

grand badger
rancid tinsel
#

damn i need to reread the material 😭

teal viper
#

It would be polymorphism if you were to override the Attack() method in an inheriting class.

rancid tinsel
#

protected override thingies

grand badger
#

Or public

rancid tinsel
#

👮

grand badger
#

Friggin’ auto correct lol

rancid tinsel
#

how does public tie into polymorphism?

teal viper
#

It doesn't. It's just an accessor modifier.

rancid tinsel
#

oh wait you mean public override right?

#

iirc it has to be the same access modifier as the method in the base class right?

grand badger
rancid tinsel
#

i only started sleeping like 2 months ago tho so might as well be

Ohh. Then you’re getting to the good parts now 👍

exciting

#

i just hope by good parts you didnt mean unit testing

teal viper
#

The point is that almost any accessor modifier would do, aside from private, as it limits the method visibility to only inside the class itself.

grand badger
rancid tinsel

#

More like inheriting classes should be aware that the method exists, and it’d be confusing if they did even if we added “private” there, so Microsoft prevented that, and made private members only accessible on EXACTLY the same type — not derived ones

#

Then added the protected modifier to allow ONLY derived types to access members marked with it

Guys does static batching work for instantiated objects at all? Prefab is marked as static, but i also tried StaticBatchingUtility.Combine() it but the meshes are still drawing separately, despite material is the same :[
Also if I enable GPU instancing on the material they start drawing instanced despite dynamic batching is disabled in Player Settings.
Uh oh batching is so confusing

Sure? That’s not what I asked tho

Like why is it static in the first place?

#

the approach you described would work

lilac dawn
#

I thought Unity will combine them if I mark it as static

grand badger
#

Ahh.. no it does some optimizations for static objects but if you have specific optimization specs you might wanna handle them explicitly

rancid tinsel
#

is .Count the same as .Length but for lists?

aside from the logic part

teal viper
grand badger
rancid tinsel
#

Trap > FireTrap / WaterTrap / ElectricTrap etc

grand badger
#

Go ahead and do the base class and ask here for feedback if u want

#

The idea is to need to write as little code on derived classes later as needed

#

(While respecting the base type’s standalone-ness, that is)

rancid tinsel
#

I think what I'll do is track the player's position in game manager and then check it against the position of the trap, then the only thing we override will be the message in the debug

grand badger
#

Nice try, but google Unity OnTriggerEnter (or +2D)

rancid tinsel

Not obvious to me, still having a hard time understanding SOs

teal viper
#

Basically, you have MonoBehaviours that you can create instances of as components on gameobjects in prefabs or scenes. And then you have SOs that don't need to be attached to anything and can just exist as assets in the project.

Interesting, I'll look into SOs, they seem useful, I just use empty gameobjects for components 😭

I've got an issue where I have a singleton being assigned in awake and other scripts want to subscribe to events on the singleton during their onenable

#

but the singleton assignment happens after the onenable of the other scripts, which I didn't expect

#

so they try to subscribe to a null instance

#

I haven't changed script execution at all but would that solve this?

#

feels hacky to do so, though

rich adder

#

I changed script execution order and it fixed it

rich adder
#

sometimes its necessary but the design could be better

grave bluff
#

but I wish there was a more robust way to do it

#

proper dependency injecting

grave bluff
#

I looked it up and apparently the execution workslike:

obj1 Awake
obj1 OnEnable
obj2 Awake
obj2 OnEnable
#

which is inconvenient :)

who would do the dependency injecting?

One script controls the Rotation, the second script is suppossed to do Torque

The Rotation with Inertia works just fine, when you try to add Torque into the mix all hell breaks loose

The Inertia part btw is VERY Rudimentary, it just increases speed over time

this implies these values are changing, you shouldnt modify data of an SO. they work differently in a build compared to editor.
either dont use an SO or rethink the system so that you arent modifying the SO data.

#

in editor they "save" because you're directly modifying the asset, which doesnt work in a build in the same way

wooden sandal
#

hm... how do they work in build?
i have a scriptable object that saves a dictionary of a string and a dataobject. is that scriptableobject rebuild on every start? because i somehow need to save a reference of the dataobject at some point..... ||unless i get a complete new reference||

If you want to save something between sessions, you need to implement a saving system.

HI ! I'm working on unity 2022.3.37, i want a gameobject to rotate (only on the vertical axis) in the direction of my vector3.
Let's said you have a gun, you shoot on a wall, the shootPoint is a vector3 and there's a compass on the ground which rotate in the direction of the shootPoint.
How could i do that ?
I've tried something like that but it rotate on the Z axis

    Vector3 direction = shootPoint - compass.transform.position;

    // Ignore the Y component to rotate only on the vertical axis
    direction.y = 0;

    // Check if the direction is not zero to avoid errors
    if (direction != Vector3.zero)
    {
        // Calculate the target rotation to point towards the shootPoint
        Quaternion targetRotation = Quaternion.LookRotation(direction);

        // Apply the target rotation, keeping the rotation constrained to the Y-axis
        compass.transform.rotation = Quaternion.Euler(90, targetRotation.eulerAngles.y, 0);
    }```
ripe shard

but how do i say "look at that direction" ?

normal arrow
ripe shard
#

transform.rotation = lookat

ripe shard
rocky canyon
#

transform.forward would be forward (local space)

ripe shard
#

to look at a thing, forward = posOfThing - posOfObserver

normal arrow
#

So it's my variable direction right ?

ripe shard
#

I sus it might

languid spire

basically i have to replace "LookRotation" to "Lookat" ?

you should never use quaternion.eulerAngles as INPUT into any method

grand badger
rocky canyon
#

gives inconsistent results

#

different values can be the same rotation..

#

gets whacked out

#

but he can probably give u a more technical reason

grand badger
#

whereas stuff like this would be so much more intuitive but fail:

image.png
#

(note: the code is extra condensed for the practical purposes of linking to discord)

night valve
#

i dont get it why there is .eulerAngles getter in the quaternion

rocky canyon
#

u can use eulers..

#

just the right way

night valve
#

so provided the rotation is around a single axis? idk about other right ways

languid spire
#

It's really very simple
Vector3 A (euler angles) -> Quaternion -> Vector3 B (euler angles)
because a Quaternion can be represented by many euler angle combinations the chances of A == B is virtually none.
So when you put euler angles INTO a Quaternion and then get euler angles OUT what you are getting will almost certainly not be what you expect
Therefore: do NOT do it!

night valve
#

thats why i question the presence of said getter ;D

languid spire
#

indeed. getter for display purposes ONLY

night valve
#

display of... incorrect results? or am i missing something obvious

languid spire
#

yes, but they can be a useful visual aid as long as you realize what you are looking at

#

the point is the results are not 'incorrect' just not what you expect

grand badger
#

imo it's not the getter that's wrong architecturally.. it's how Unity handles rotation

queen adder
#

just learn some abstract algebra and use quaternions tbh

#

imo

languid spire
#

no, thats just the way Quaternions work, Unity has no control over that

night valve
rocky canyon
#

i use eulers all the time.. alot of the time they're fine..

night valve
#

(tried with constructing a rotation matrix manually then comparing to unity's rotation. Results were equal)

grand badger
#

I don't know.. they handle Quaternion operations correctly, but if u set eulerAngles instead it could use a random quaternion that's not related to your previous frame's data

#

I definitely see room for improvement there, but could also be brushed off as just QOL and nitpicking

#

(e.g. if you do Quaternion.MoveTowards it'll respect the current state)

timber tide
#

all you really need is quaternion.angleaxis and quaternion.lookat

languid spire
grand badger
#

Quaternion.LookAt is bleh 😛

night valve
#

AngleAxis is all you need tbh

grand badger
timber tide
#

Ah, yeah it's LookRotation

#

then slerp to it

night valve
#

a nice learning task would be re-creating LookAt behavior by using AngleAxis only. helped me to understand how to use quaternions

grand badger
#

yeah but honestly the only thing that's handled correctly is the multiply operation

#

someNewQuaternion * transform.rotation

#

-- if you care about the previous state, that is

night valve
#

in fact its just 3x3*1x3 matrix multiplication (correct me if im wrong)

rocky canyon
#

if u ever really wanna learn quaternions build a telescope, anti-aircraft gun, or anything like that that rotates on 1 axis and then on another.. (seperately but together to track a target in 3D space)

#

w/ limits and all that.. it'll test ur sanity as well

grand badger
#

rotation is just one line in that matrix -- that transform matrix

night valve
#

ok thx

eternal needle
night valve
#

really? i may messed something up, but was pretty sure that A rows and B collums have to be the same

eternal needle
#

The numbers are the other way around, should be 3x3 and 3x1

night valve
#

righht, thanks

eternal needle
#

Anyways yea most rotation problems can be solved using like 3 different quaternion functions, most dont really need to know the actual math

#

The actual math is quite complex to begin with

grand badger
#

or you could multiply a 1x3 with a 3x3 lol.. order matters here -- same with quaternions

Hey guys, Microsoft Visual studio or Visual studio code. Which one is better to use with Unity?

Visual Studio guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

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

q1 * q2 = (w1w2 - x1x2 - y1y2 - z1z2, 
           w1x2 + x1w2 + y1z2 - z1y2, 
           w1y2 - x1z2 + y1w2 + z1x2, 
           w1z2 + x1y2 - y1x2 + z1w2)

Ye I mean making tower defense turrets should be the most basic thing to do with quaternions

languid spire
# rocky canyon

that's cheating, a tank does not have a fixed position/rotation body

rocky canyon
#

but as far as i know its all local space

#

should work fine 👍 😝

languid spire
#

tell you what, and this applies to anyone, when you have successfully implemented a working tank controller you can consider yourself a 'Master of Rotation'

night valve
#

But there is no roll, only yaw an pitch. I'd say a working spaceship controller would make you a true master

languid spire
#

of course there is roll

bronze estuary
#

and I just downloaded Unity 6 preview for Junior programmer from Unity Learn.. is that okay?

languid spire
night valve
#

Oh, right. Roll of entire tank. Makes sense

rocky canyon
#

just an exercise.. was welll worth it.. b/c thats when it finally sank in about what steve had been saying about eulers

night valve
#

Predictive aiming ❤️ was it difficult to make it always hit the target?

rocky canyon
#

where does VSCode store it's global settings.json file?

#

i know each project has one inside the .vscode folder.. but i modified my line-numbers w/ a "workbench.colorCustomizations": { "editorLineNumber.foreground": "#ffff", } block like this.. and it applies to all my projects.. just can't remember how i found it

rocky canyon
#

sometimes it still misses b/c its using rigidbody projectiles

languid spire
rocky canyon
#

theres more code on the target than the bullets (it takes its velocity each frame and predicts where it'll be by the time the bullet would travel X distance

night valve
#

Was doing something similar in uefn TD game mode. Can confirm that it was difficult as well ;D for linear target movement it was always a hit, but if target suddenly turns, well... I'm not proud of it anyways lmao

``` well actually its simpler than i remember
rocky canyon
#

or else the turrets gonna just be wasting ammo

night valve
#

Yep

rocky canyon
#

but my system sucks.. b/c the bullet has to ask the turret each frame.. what the projectiles speed w/ be and then do its prediction

#

and then the turrets always searching for projectiles

#

not the best..

languid spire
rocky canyon
#

😅

night valve
#

Isn't that to keep things realistic, bullet should ask tower just once, right before a shot?

rocky canyon
#

bullet gets fired.. (and finds tower)
it asks the tower what the projectile speed will be..
then takes it's current velocity and projects where it will be when that speed will cover that distance.. then it just projectiles a invisible sphere collider out in front... the turret just constantly aims at it and sprays

B2F1FE22-7860-4C49-8A98-1D9420036483.png
#

my little hacky way... (so its not actually aiming in front.. its aiming directly at...) a projectile that isnt there

night valve
#

I guess it's sufficient for a game ;D

rocky canyon

#

just bad at words, yaknow

#

but when i seen bool? i just wanted ot figure out what it was exactly lol

burnt vapor
rocky canyon
#

its just a static utilities class..

burnt vapor
#

Because you can be sure the constructor is called, so this extra check is not required

rocky canyon
#

it doesnt need to be present.. but alot of errors in my codebase specifically if its missing

rocky canyon
#

just now getting comfortable w/ properies and getters and setters and whatnot

burnt vapor
#

That's fine, just interested in seeing the reason for it

rocky canyon
languid spire
burnt vapor
#

Often a lot of code is added that would make sure the logic is solid, but often it's not required

burnt vapor
# rocky canyon

But this constructor does nothing. I would assume it sets data somehow?

strong mica
burnt vapor
#

You mentioned that you want to make sure the static class is installed or something. Are you unsure if the static class exists when you try to use it?

rocky canyon
burnt vapor
#

Because it always exists. It has no instance so it can't be null

languid spire
rocky canyon
#

the code all functions w/o it.

#

its just little debugging and helper stuffs thats not vital to functionallity. but if its not present i'd like to display a console message or something saying to either add the static class.. or remove the logic that calls upon it

burnt vapor
#

But you don't add it, you literally can't

#

If you have a static class in your code like this, it will always exist

#

I'm sure there's some logic to it when it's properly constructed, but it will always be there when you use it

#

The only reason why you might want to do this is if your static class needs external data that must be initialized, which might be done through some separate "Initialize" method. But you don't have this, and even if you do this would be in the constructor most likely.

#

And if you had that I strongly suggested you got rid of it because that's bad atwhatcost

rocky canyon
#

@burnt vapor alrighty, i think i see where ur coming from. I'm doing some more research on it..

So, I have a codebase.
This Static Utils class just has some helper functions and whatnot..
It's would not change the over-all functionallity of the project.. but it would require a bit of refactoring just to remove some of those function calls.

If its not included then obviously they'd be some errors.. I was just trying to make a graceful attempt at allowing the rest of the code to function w/o it being present.. (maybe giving u some logs and stuff)..

and i'd be lying if i said i knew the appropriate way to handle that lol
(still learning)

burnt vapor
#

A utils class is a very good idea, that's not an issue

#

I often make a lot myself

rocky canyon
#

well, the project is made up of different pieces and stuff.. (theres a chance the static class doesn't make it into the project)

burnt vapor
#

If it didn't exist, then you would be not even be able to use it because the intellisense could not find it

rocky canyon
#

soo.. if i duplicate my project.. and delete the utils class.. ur telling me it still exists?

burnt vapor
#

For example, if it's in a different unreferenced assembly definition

burnt vapor
rocky canyon
burnt vapor
#

Also, your code would not compile

rocky canyon

#

(to be clear, static classes are initialized when they're first accessed)
