What does Debug.Log(rootObjects[7].activeInHierarchy); log in that Start method

[rocky canyon]

ahh gotcha gotcha.. 👍

[delicate zinc]

its saying true

i just tried restarting unity to see if it was just being weird but its still doing it

[strong wren]

Double check with ``Debug.Log($"{rootObjects[7].name} {rootObjects[7].activeInHierarchy}");`

Though I suppose we should check the CamContainer too

[delicate zinc]

yea these are both true

[strong wren]

Debug.Log($"{rootObjects[7].transform.GetChild(0).name} {rootObjects[7].transform.GetChild(0).gameObject.activeInHierarchy}");

[delicate zinc]

still all true
sorry if this is annoying u btw

[strong wren]

Running out of ideas. You are running these from the Start method with the GameObject.Finds?

[delicate zinc]

yeah
at this point its probably just a bug or smt cos it should be working

ive tried tagging the objects to find them and using findgameobjectwithtag and it wasnt working either

It I need help wait one thing

[steep rose]

then ask your question in a correct channel, if it is about modding though, do not do it as we do not do that here

[stuck monolith]

It code

[stuck monolith]

And adding it to the model

[steep rose]

adding a script to a gameobject?

[stuck monolith]

I try 100 of times but still

[polar acorn]

Take a moment, formulate an entire coherent question in a single message, then ask it

[stuck monolith]

On ph

[steep rose]

I do not know what that means, are you getting an error?

[stuck monolith]

No I just need the players script and how to insert it

[steep rose]

drag it onto the gameobject

[stuck monolith]

I try taht and I not have a script

[steep rose]

do you have a script made?

[polar acorn]

You have to make the script first

[stuck monolith]

No

Taht waht I need

[polar acorn]

Then make one

[steep rose]

go into the project window and rightclick -> create and make a new script

or you could make one in the inspector, nobody does that though lets be real here

Does throwing your own exceptions break the program? I basically just a more attention grabbing Debug.Log

Or does it just continue along no problem

[slender nymph]

throwing an exception means that the method being executed halts there, which of course makes that continue; entirely pointless since it can't continue past that point

[blissful yew]

I like exceptions because they are easier to spott in the console. Is there a way to get that without halting anything?

[slender nymph]

Debug.LogError

[wintry quarry]

Debug.LogError

[slender nymph]

or just use rich text tags to make your logs standout more (or both)

[blissful yew]

So what's even the point of throwing your own exceptions?

[wintry quarry]

Throwing exceptions is definitely not something to just do casually. It stops the entire control flow of the program

[rocky canyon]

rich text + ur own static logging class ftw

[wintry quarry]

To handle exceptional circumstances. Usually around file processing or something where you can handle it e.g. by showing the user an error message. Like "your save file is corrupted"

[blissful yew]

What's the benefit of the custom logging class?

[wintry quarry]

Or "could not connect to the multiplayer server"

[rocky canyon]

for me its so they stand out..

i can call Dbug.Green("ForExample"); or Dbug.Yellow.. and then its just rich-text in a regular Debug.Log

[naive pawn]

when something happens where you can't continue in code, like praetor mentioned, exceptional circumstances that shouldn't be happening
exceptions are a way to escape the code entirely to ensure that it doesn't break more from what's already going on

[wintry quarry]

Continue is redundant if there's no code that will run after it in the loop.

[blissful yew]

How much do you guys use exceptions?

[wintry quarry]

Rarely in game dev

[naive pawn]

not typically in game dev

[wintry quarry]

Depends what you mean by "use" though

[blissful yew]

yeah it doesn't seem useful unless things get very complex maybe

[wintry quarry]

I handle existing exceptions like file reading exceptions all the time for saved game systems

[naive pawn]

i don't have a ton of experience to back this up, but from what i do have, they're more relevant for longer, contained processes, like data processing

[blissful yew]

With try catch?

[wintry quarry]

Yes

[naive pawn]

well, exceptions exist as part of the language, not part of unity

they have their use cases

[wintry quarry]

Some languages don't have exceptions BTW. C and Go for example use a different approach.

[naive pawn]

and some interfaces use a similar approach to that with signaling return codes
Int.TryParse, the return value indicates whether it was valid or not instead of an error

or Physics.Raycast

or having both a successful value and error value be possible, like NaN from invalid floating point operations

these all encode "error" states without using exceptions

exceptions are more to control flow than just representing states, they have specific behavior like bubbling up

[mild owl]

Whenever i change the jumpPower Float the jump hight doesnt change could somebody tell me why

[steep rose]

you are declaring it again under JumpKeyWasPressed, remove the float next to it

[languid spire]

because you declared it as a local variable

[polar acorn]

Why would it? You aren't using it anywhere

[mild owl]

Oh thanks

[queen adder]

hi, is there anyone who could answer this: is it possible to make 2 certain scripts that both disable a certain gameobject without overriding one another. Im currently making 2 hiding spots for my game: a table and a locker, the locker seems to work perfectly fine and disables the player within the scene but the table doesnt seem to do so?

im pretty new to C# and unity in general so please go easy on me

i dont think im the only newbie in the chat here

[polar acorn]

Put a third script on the object you want to disable that the first two reference, and have each one tell that script "Hey, you're supposed to be enabled/disabled" and have that third script keep track of how many things are telling it to be disabled. If any of them are still telling it to be disabled, it should disable the object

[queen adder]

i was recommended to do everything into one file because i was pretty much repeating myself in the second script

[queen adder]

like in a static way?

i actually havent come up with that 😭

i still need to learn a lot more about C#

[polar acorn]

Probably. You can put the same script on multiple objects

You'd need one script that handles the object turning on/off, then however many other scripts you'd need for the different ways that script can be told to turn on or off

[queen adder]

imma see how im going to do that

but ill definetly keep your suggestions in the back of my mind

thank you!

[queen adder]

yo dude, i just tried oyur suggestion and it worked! I had to ask chatgpt a couple of times but im learning from it

[nocturne parcel]

With the new input system, is it ok to verify player input in FixedUpdate?

I remember it wasn't ok with the old, but I guess this changed?

[naive pawn]

input is frame-based

the press and release will be true for 1 frame each

you can check if it's currently being held in FixedUpdate like you could before

[nocturne parcel]

What about read value?

[naive pawn]

ah well same as checking if it's held

the values get updated per frame

[cosmic dagger]

you're better off using an event to assign a variable the read input value when the button is performed . . .

[naive pawn]

(which will happen per frame)

[knotty arch]

Hello. I have a projectile that I move by using rb.AddForce() which ForceMode is an Impulse. When I it collides with a wall, there is a chance where the projectile can spawn an enemy when destroyed. The problem is that before the projectiles is destroyed it continues moving after it collides with the wall, so the enemy spawns outside the room (this happens sometimes). The Rigidbody has continuous collision detection.

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

public class CheeseProyectile : MonoBehaviour
{
    public float speed;
    private Rigidbody2D rb;
    public Vector3 angle;
    public GameObject cheeseEnemy;
    public BoxCollider2D rataCollider;
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        rb.AddForce(speed * angle, ForceMode2D.Impulse);
    }
    private void OnTriggerEnter2D(Collider2D col)
    {
        string colTag = col.gameObject.tag;
        if (colTag == "Player" || colTag == "Room")
        {
            if (colTag == "Player")
            {
                col.gameObject.GetComponent<NaachoHeartSystem>().Damage(1);
                Destroy(gameObject);
            }
            else if (Random.value < 0.2f)
            {
                GameObject queso = Instantiate(cheeseEnemy, transform.position, Quaternion.identity, transform.parent);
                EnemyEnabler enemyEnabler = queso.GetComponent<EnemyEnabler>();
                enemyEnabler.GetComponentsReferences();
                enemyEnabler.SetComponents(true);
                Physics2D.IgnoreCollision(queso.GetComponent<BoxCollider2D>(), rataCollider);
                Destroy(gameObject);
            }
            Destroy(gameObject);
        }
    }
}

[wintry quarry]

Since you're using a Trigger collider, it will have to partially pass through/overlap the wall before the collision is detected

to prevent this you would either:

• use a non-trigger and OnCollisionEnter2D
• do your own manual CircleCasting or RayCasting in FixedUpdate to detect the collision instead of using a callback

Also there is no reason to have Destroy(gameObject); three times in your code

once is sufficient

[knotty arch]

Ok, I will try that

[knotty arch]

That's true 😅

        //break sprite
        float percentageMined = (liveTileData.currentBreakTime / liveTileData.maxBreakTime) * 100;
        S_TileManager.SetBreakSprite(tileTargettedPos, percentageMined);
        liveTileData.TouchTile(); 

        yield return null;
    }

    if (CheckIfValidTile(tileTargettedPos))
    {
        StartCoroutine(UntouchedTileTimer(tileTargettedPos));
    }

    //nothing happened
    yield return null;
}```

Why is this Coroutine taking longer than 2 seconds? I've set liveTileData.maxBreakTime to be 2 seconds.

The code is a coroutine that happens when the player holds their mouse over a tile like in terraria and mines it. However, hovering and breaking the tile takes longer than expected.

Does this mean my code is making it slow?

Or have I got an error somewhere ?

[buoyant schooner]

Nvm! My Timing in real life is off lol

it just felt wayyy longer than 2 seconds

i want to use my method on the object

but it says this

[teal viper]

You're likely overriding the variable value on line 53. Possibly with a null. Log the value before and after that line.

Ah, nevermind that. It's a difference variable

[burnt skiff]

yea

[teal viper]

This looks weird. I've never seen a syntax like that. What are you trying to do here?
drone => drone.ID

[burnt skiff]

its a key selector used to specify that i want to create the binary tree by the drone's ID

my drone has many attributes and i want to create the binary tree based on its ID

[teal viper]

Is that a lambda expression?🤔

[burnt skiff]

yea

[teal viper]

Share the whole error details.

Select the error and take a screenshot of the whole console

[teal viper]

I see. So that's when the lambda is invoked. drone is likely being null there.

[burnt skiff]

oh alright maybe i need to change it to agent

still the same

[teal viper]

It's likely a value provided by the tree, so changing the name of the variable wouldn't really do anything

[burnt skiff]

https://paste.ofcode.org/mdzPsWfnriw7E5aNcDprky

this is the drone code

[teal viper]

The drone code is unrelated. The value is provided from DroneBTCommunication

[burnt skiff]

oh alright

[teal viper]

I feel like you don't understand how your own code works, do you?

[toxic yacht]

at line 32 in DroneBTCommunication what is the behavior you want if drone is null? or should drone ever be null?

int nodeKey = keySelector(node.drone); // node.drone is null
drone => drone.ID // results in null ref for drone passed to lambda at line 56 in Flock

just like dlich said

[burnt skiff]

some parts yea im actually new to this cause i have to this for a course and im referencing some seniors work

[burnt skiff]

but how could drone be null if i already gave it the arrays

oh wait

nvm

before i applied the method onto the object i partitioned the drones based on a pivot and stored them into arrays, this method works fine but how does it suddenly become null

once i remove line 56 the code works fine so the lessthanorequal array does exist and it contains my drone objects inside it

[teal viper]

It feels really weird to me that you're using pretty complex syntax(that a beginner wouldn't know how to use), yet have difficulties debugging a null reference error.

[toxic yacht]

i think I see what's happening

nevermind I was looking at the insertion and though the root assignment was messed up. one of the drones in the drone array must be null. I'd suggest moving the lessIndex++ out of the array access. ik in C that's supposed to happen after operations but that's making my spidey sense tingle.

my feeling is that the root node's drone is being assigned to null (a.k.a. drones[0] is null), so when the second node insertion is done, the KeySelector call on line 32 results in the null ref.

the call stack for the error always being at the root node despite drones being generated randomly makes me think this is a one off error, and the only place I think of a one off error happening is in partition drones.

[burnt skiff]

i printed all of the values inside the partition array and i cant find any drones that could be null

[wintry quarry]

But it's pretty clear you never assigned instance

your code makes no attempt to do so
so you're getting a very typical NRE

[toxic yacht]

actually is the stack trace for the error always the same? or was it just that one that happened to be at the root?

[radiant glen]

Okay, how do I assign an instance? and what is a NRE?

[wintry quarry]

You assign variables in C# with =
instance is just the name of the variable you are trying to access when you get that error.

[burnt skiff]

its always the same

[wintry quarry]

@radiant glen see you are trying to access this Health.instance variable. Since that variable is null, you get an error. You cannot access a null reference or you get a NullReferenceException.

It is null because you never assigned it. You assign variables in C# with =

[radiant glen]

Okay, I see, so what do I need to assign then?

[wintry quarry]

The variable

It seems like you're trying to do the singleton pattern

but you did not fully implement it

typically you would do something like this:

void Awake() {
  instance = this;
}``` in the `Health` script

See how you can assign a variable with =

[radiant glen]

Oh! Okay that makes sense I see

Perfect that worked thank you!

[teal viper]

Instead of logging, I'd try to step through the code with a debugger, when the drone is being null. It should be a matter of seconds/minutes to figure out where the null is coming from.

[burnt skiff]

how do i use the debugger in unity

[toxic yacht]

its a bit of a setup process https://docs.unity3d.com/6000.0/Documentation/Manual/managed-code-debugging.html

[burnt skiff]

it seems that the error is due to the root being null

because when i add a debug log to check if root is null before adding nodes it appears root is null and when i put it after the program just stops

so im guessing that's where the problem is

[toxic yacht]

the root starts off as null, but is assigned with line 29 in DroneBTCommunication. However, the root's drone is null, which causes the error. The only way I can see the root's drone being null is if the first drone in the drones array is null. but if everything in the drones array is assigned then that's a headscratcher.

[burnt skiff]

yea i figured out the error it was because when i was creating the node i didnt specify it to the drones inside the array it just used the local variable drones which is null, i fixed it by just adding this.drone

thank you guys for the help

[toxic yacht]

they fooled us all lol

Hi, I've been losing my mind with this one since yesterday 😭
So basically, C# implementation of a file watcher is awful(and that's an understatement), and for some reason, gets triggered mutliple times when a file changes, and even detects incorrect events.
None of that would matter to me, I just need it to trigger when the file is changed, renamed or deleted, which it sort of does, but multiple times.
Issue is, when it triggers multiple times, and I am guessing here, it cancels the execution of a method it previously called?????
Trust me, I am as confused as you are probably.
I used rider to try and debug, it basically kept jumping all over the place 🤦‍♂️
So finally, I decided to see if it's me being majorly incompetent, and to my surprise, I wasn't.
Calling the exact same function the file change event calls results in flawless behavior and the expected result.
And due to debug logs I placed all throughout code, I was able to determine that execution of functions literally gets cancelled by another event trigger or something, I am losing my mind at this point.
I would really appreciate someone helping me debug this one 🥺
Here's the script responsible for dealing with config logic.
Lines of significance are:
9 - Calling the function on a keypress that assured me my logic worked just fine
110 - FSW setup and the function I am calling
137 - Function that stops midway through when called by a fsw, but works fine otherwise

[burnt vapor]

if (bla is x or y)

}

Probably doesn't even work in current Unity

if (lastPositionPoint.transform.position is (Vector3.left * transform.position) or (-Vector3.left * transform.position))

gotta love c# 9

[eager spindle]

I always wondered why when a canvas GameObject is automatically created they don't put the event system onto the same GameObject

[astral falcon]

Imagine having more than one UI canvas

[eager spindle]

true but to be fair the engine already detects if a event system is in the scene so it wouldn't add the event system to the new GameObject

[burnt vapor]

Can't wait until they update their codebase so that I can suggest actual proper code

[astral falcon]

So you gonna disable the UI, cause its the main menu or whatever. what then?

[languid spire]

Because it aplies to All canvases and you may have many

[languid spire]

and what would happen when you disable the one canvas that happens to hold the event system?

[queen adder]

Has anyone knowledge about with DotTween. I look up Stack Overflow, but in my code is still a syntax error

 transform.DOScale(new Vector3(0,0,0) ,1f).onComplete(() => Destroy(gameObject,0.1f));

[naive pawn]

it's a field, don't you need to assign to that

[umbral bough]

just a wild guess, onComplete() is an action and you gotta do onComplete => Destroy(gameObject, 0.1f); instead

[naive pawn]

wdym wild guess it says so right there

[queen adder]

Still a syntax error

[umbral bough]

oh, I missed that completely 🤦‍♂️
I just saw a thing called onSomething and assumed it's an action.

[naive pawn]

but also that's not how you set an action

like i said, you need to assign to it

onComplete = () => Destroy(...);

[umbral bough]

my bad, I am tired, you should do what that guy suggested

[naive pawn]

this is invalid syntax; originally it was invalid semantically

[queen adder]

That worked

[hexed terrace]

You want to use .OnComplete() not .onComplete()

IIRC

[naive pawn]

a syntax error means c# can't read your code at all
what you had before was a semantic issue; it sees what you're trying to do but it's invalid

[naive pawn]

and yeah if this exists it would make more sense

actually seems like it just sets onComplete. so not sure what the benefit over the assignment is if it has the same behavior

[naive pawn]

OnComplete seems to be documented, at least..?

[hexed terrace]

DOTween lets you string a load of things together, so you want the () to be able to add another extension

[queen adder]

transform.DOScale(new Vector3(0,0,0) ,1f).OnComplete(() => Destroy(gameObject));
``` This works, thank you for your help

[naive pawn]

why's onComplete accessible though

[hexed terrace]

You can also just do

[umbral bough]

[kindred spade]

hey there! i'm following a tutorial on how to make a flappy bird game for my first project just i can't seem to figure out why the code doesn't work here is my code:
the problem is that for some reason when i touch the trigger it doesnt move my score up!

[hexed terrace]

do you get the 'addc' log in the console?

any errors?

what debugging have you done?

[burnt vapor]

100% this

Not just for readability

Stuff like events need a proper method reference and not a lambda if you want to unsubscribe, so get used to this instead

[kindred spade]

i've tried sending a msg to the debug when it touches but it doesnt work

im pretty sure that my addscore code works because i added score with a contextmenu

[hexed terrace]

so your physics isn't setup correctly (colliders/ rigidbody/ etc) - go back through the tutorial where it tells you about adding this stuff and see what you missed

[kindred spade]

ahhhh

[hexed terrace]

If 'addc' isn't being printed to console, OnTriggerEnter2D isn't being called.

[kindred spade]

ii have my sprite set to rigidbody 2d and my trigger to box collider

aha

[hexed terrace]

Your sprite isn't "set to rigidbody"

Your player GameObject has a rigidbody component added

[kindred spade]

my bad i don't know how to call everything yet xP

my sprite has a rigidbody 2d for gravity and box collider 2d to collide and my pipe has a box collider 2d i don't get what i've done wrong i already checked the tutorial a vew times because i thought i did this wrong

[languid spire]

show the inspectors of both objects

[kindred spade]

this one is for the trigger

this one is for the sprite

[languid spire]

this is not a BoxCollider2D

[kindred spade]

oh lord

im a dumdum

tank you

that explains it

it works thanks so much!

[languid spire]

fyi. If you want to do dev work you have to pay attention to every detail, no matter how small

[hexed terrace]

but also, don't get hung up when you do make small mistakes - we all do it

[kindred spade]

i don't know if i'll become a dev i'm far far away from that i'm just trying to learn something instead of scrolling youtube all day haha

[languid spire]

as soon as you touch a program like Unity what you are doing is dev work

[upbeat snow]

hi guys, I currently have a script in a GameManager gameobject that calls a function whenever a value is added to a score. How can i detect whenever the function is called so that my ScoreUI (which is another gameobject) could call an animation? tysm

[cosmic dagger]

you can use an event . . .

[upbeat snow]

alright will look into it im new in this lol

[cosmic dagger]

a script on your ScoreUI GameObject will subscribe to the event. this event is a field (class variable) created on the script attached to your GameManager. when the event is invoked, every method subscribed to it will execute . . .

[upbeat snow]

yup i kind of figured it out just now, i just added the function onto the dropdown menu of the script event tab :)

tyty

[twilit rivet]

nvm

[crimson widget]

Hey, how do I set a splines end point position through c#? I am trying to move and update how a spline is shaped at runtime, but I cant find the correct method or whatever

[astral falcon]

I guess you just have to add the position as last knot in the array of knots

[upbeat snow]

hi guys, here I have script "points" attached to an event in which triggers the "triggerAnimation" function when called; however the animation seem to only play the first time the event is called and it doesn't work afterwards. The console message does continue to show up tho, anyone know what the possible problem would be? animator also provided here if it helps tyty

[astral falcon]

can it loop and maybe you need to reset the clip to play from start

[upbeat snow]

if i enable loop time (as shown here) the animation would just keep repeating after the event was triggered once lol

and when i turn it off it's the situation i mentioned earlier :/

[astral falcon]

Again, did you revert it to start before playing?

[polar acorn]

It can't exit that state

If you don't loop it, it'll play once when you enter the state and then be there forever

[queen adder]

Sorry i have a very basic Question, how to accesse indivual Compontes in a good/professional way? Even then they don't have a Script attached. What i used to far ```cs

// Option 1
private TextMeshPro moneyText;

private void Awake() {
    moneyText = GameObject.FindGameObjectWithTag("MoneyText").GetComponent<TextMeshPro>();

}

//Option 2
public GameObject moneyTextObject; // Drag and drop Gameobject with editor
private TextMeshPro moneyText;

private void Awake() {
    moneyText = moneyTextObject.GetComponent<TextMeshPro>();

[polar acorn]

Basically any method containing the word Find should be avoided at any cost

[wintry quarry]

Option 3:

public TextMeshPro moneyText;``` drag and drop

and you're done

[polar acorn]

And the correct way is to just make moneyText public and drag it in and have no code at all

[wintry quarry]

And option 4, which is really the most "professional" way generally:

[SerializeField] private TextMeshPro _moneyText;```

[queen adder]

But i can't drag the Gameobject from the hierarchy into this public Field (i think i't because, the is a Componet of a GameObject)

[wintry quarry]

No you can't drag it because it's a TextMeshProUGUI

not a TextMeshPro

[polar acorn]

If you drag an object that has that component onto a variable that holds a component, it will use the component

[wintry quarry]

You should, in the future, just use TMP_Text instead of either of those

it works for both

[queen adder]

Oh there not the same

[wintry quarry]

no

[queen adder]

Okay Thanks that's a really good tip

[frank zodiac]

using UnityEngine;

public class World : MonoBehaviour
{
    [SerializeField] private int _width = 10;
    [SerializeField] private int _height = 10;

    private Tile[,] _tiles;

    private void Awake()
    {
        _tiles = new Tile[_width, _height];
    }

    private void Start()
    {
        for (int x = 0; x < _width; x++)
        {
            for (int y = 0; y < _height; y++)
            {
                GameObject tile = new GameObject();
                tile.name = $"Tile ({x}, {y})";
                tile.transform.position = new Vector2(x, y);
                tile.AddComponent<Tile>();
                tile.AddComponent<SpriteRenderer>();
            }
        }
    }
}

is there a less performance-intensive way to instantiate a large number of gameobjects?

[rich adder]

make them prefabs? so you already have the required components? shave off a few ms (if even that)

[frank zodiac]

Would that make a virtual difference?

Like in terms of performance

[rich adder]

try it and see, not likely anything substantial
Idk if Instantiate is better than New GameObject

cloning vs actual new() 🤷‍♂️

[timber tide]

wtf constructing a whole new gameobject

[obsidian mesa]

Hello, a question, if I pass my code here, could you tell me what the error is about my character not jumping?

[rich adder]

[cosmic dagger]

doing new GameObject() is worse because you have to manually add all the necessary components instead of using a prefab with everything all set up . . .

[night raptor]

You could also try to create one object and instantiate it again in the loop without creating a prefab, I would guess prefabs are somehow optimized for that though, but as far as I know, nothing prevents you from cloning existing object with Instantiate too

[obsidian mesa]

It tells me I can't upload the code

[ripe matrix]

Hey, i have this error where i cannot make a reference to the camera fro some reason. Does anyone know why?

[rich adder]

you mean drag n drop is not working?

[languid spire]

you have your own class called Camera

[ripe matrix]

yes

[rich adder]

one of the object is scene and other is prefab?

[ripe matrix]

yes

[verbal dome]

I doubt its their own class, it has camera icon

[rich adder]

thats probably why

you cannot drag Scene objects in the Prefab

[ripe matrix]

Is there another way to reference it?

[rich adder]

pass the reference on spawn

[ripe matrix]

How do i do that?

[rich adder]

https://unity.huh.how/references/prefabs-referencing-components

[ripe matrix]

Ok, thanks!

[rich adder]

with camera you probably get away with Camera.main property but this is probably better to learn properly from link above for other objects too

[frail hawk]

you can also keep the reference on the script that instantiates and after instatiating just add the reference to the prefab

[rich adder]

yes thats what the link i sent suggests you do

[frail hawk]

oh yeah, i see it now, it is the cleanient soloution

[rich adder]

yeah its a simple form of DI (dependency injection), very handy for other things too

[frail hawk]

direct injection

oh yeah

i think unity should provide an easier solution, people ask this thing alot.

in fact one of the most asked questions

mayn people start to do foolish things such as Find

[rich adder]

I rather like the DI that .net apps have, idk games are a bit different

they do have things like ZenJect (third party though)

[dry jungle]

Hi in my game i can't look up, does someone knows how to fix it?

[steep rose]

look at the clamp

also you should use the floats you made for the clamp

[rich adder]

you should not be using Time.deltaTime calculations on mouse Inputs

thats why you set the sensitivity so high

mouse inputs are already framerate - independent

also your clamp is wrong , doing 90 90 when it should be -90/90

if you have top and bottom clamp variables, but why aren't you using them

[rancid tinsel]

if I'm running an if (audioSource.isPlaying == false) every frame but the audio source is set to loop, would that ever go through? is there a frame or moment between the loops where that is set to false or is that not something i need to worry about

[rich adder]

wouldn't it just be easier to test this lol

[timber tide]

You only need to set it false once if that's what you're asking

[rancid tinsel]

idk how id go about testing it considering it could very well miss it depending on how it works

[rancid tinsel]

i meant without setting it to false, just with loop enabled and playing normally

[rich adder]

put a Debug.Log inside the if statement ?

if its just loop its probably still isPlaying until you call Stop() but dont take my word for it

[rancid tinsel]

thats what im assuming but wanted to make sure

[timber tide]

audio looping isn't something independent. If the streamer isn't playing then the audio cannot play thus cannot loop

[rancid tinsel]

is that because it can only update isPlaying once a frame due to how the engine works

or is there a different reason

[rich adder]

I would just test it and make sure it works how you expect in your specific use case

[dry jungle]

Does anyone know how do I fix this error?

[rich adder]

mate . Configure your IDE first

[polar acorn]

What error

[dry jungle]

At the bottom of the screenshot

[polar acorn]

I don't see an error

[slender nymph]

not only do you need to configure your IDE as you've been instructed before, but you also should learn the difference between an error and a warning

[dry jungle]

Ok

But It says Error

[slender nymph]

yes but the warning you are looking at is not the error. configure your IDE

[polar acorn]

Okay, so look at your compile errors

You haven't shown any

[steep rose]

open your console

Visual Studio 2019 is your IDE, please follow the bot very carefully

[dry jungle]

ok

[prisma thicket]

oh the error is gone from the screenshot, im just confused on why the debug keep saying Raycast did not hit anything.
UnityEngine.Debug:Log (object)

when i am right clicking on the tree and it should open the context menu

[slender nymph]

you raycast from the position of whatever object has this component in the direction that object is facing. it has nothing to do with where your mouse might be located

[prisma thicket]

omg pls dont tell me

[fickle plume]

@dry jungle Should install 2022 from the Hub as in instructions there. It's faster and it will be properly setup out of the box. Will just have to switch to it in preferences.

[slender nymph]

if you want to raycast from the mouse then you need to use the camera to create a ray from the mouse's position and use that

[prisma thicket]

pls dont tell me its just this.....

[slender nymph]

(it is)

[prisma thicket]

i hate myself

[dry jungle]

I did it

i've been trying to get a code up and running for a 3d platformer practice game, etc. But i'm having the worst kind of trouble with the rigidbody physics, and find my dude sliding all across the place on inclines, and i have no idea why it's happening. it's not even downslops, that could be debatably useful, but i'll slide horizontally off a ledge or something it's slightly inclined or enclosed by walls. i don't really understand why.

ok so i tried it and when i right click on tree nothing is happening

[dry jungle]

It's still there

[slender nymph]

what is the value of interactionRange and how far is the tree from your camera?

[fickle plume]

You will need to provide full information for that. Controlling script, character object inspector, and maybe a video of the behavior.

why isn't the particle playing when i jump i've been trying to figure it out for the last 30 minutes even asked chat gpt but i might just be stupid

oh the interact range i have set to 20 and the camera angle is like this

does the tree have a collider on it and is your ray long enough to reach that collider?

[steep rose]

read this and use the keycodes from it #💻┃code-beginner message

the correct keycodes

[dry jungle]

BYE

[prisma thicket]

it has a mesh collider and idk how far the raycast is

[slender nymph]

well you're drawing the raycast, does it appear to be long enough to reach the tree? also is the tree's collider convex?

[steep rose]

bye what? are you not going to fix the issue you had?

[slender nymph]

they came here for answers, not to read /s

[steep rose]

that is an answer 🤷‍♂️

[stuck palm]

How can i rotate this sphere along the local red line?

[prisma thicket]

yeah its convex is on but how can i check how far is the raycast? (btw im sorry im grabbing food from the kitchen)

[slender nymph]

rotate around its local y axis

[steep rose]

using its transform

[slender nymph]

so you have these neat things called eyes that can physically see the line that you are already drawing in the scene

[prisma thicket]

wait a minute that giant white line square box?

[slender nymph]

no, you are drawing a red line to represent the raycast. do you just not even know your own code?

[prisma thicket]

im only know half of it...

[slender nymph]

let me guess, it's AI generated and you felt that wasn't important to disclose?

[prisma thicket]

not that

[slender nymph]

well then if it isn't ai generated then you wrote the code and you wrote the comment that literally says "visualize the ray"

alr alr maybe i ask a little on how to create a contextmenu that all

That's everything. And I am learning through the tutorials, but I've come across through experimentation and wanted to know if it was salvageable.

[slender nymph]

cool so i don't help with ai generated code. good luck.
also give #📖┃code-of-conduct a read, particularly the part where it says not to post unverified ai responses in questions

[slender nymph]

you allocate an array every time you call this method. use the non allocating version of OverlapCircle

[hexed terrace]

Use the profiler to find out.

But in general, you should be caching things that you use multiple times - especially when you're doing a GetComponent

[gleaming kraken]

alright, i'll do that, thank you!

[gleaming kraken]

i'm assuming there's documentation for caching. I'll check it out, thanks!

[slender nymph]

it's literally just storing it in a variable

[timber tide]

usually the IDE asks if you want to use the nonalloc version

[gleaming kraken]

really? That's it?

[languid spire]

do your distance check before the GetComponents

[hexed terrace]

that's what caching is

[slender nymph]

yes, instead of calling GetComponent a bunch of times for the same component, call it once and store it in a variable and reuse that variable in each place you were initially calling GetComponent for that type

[fickle plume]

Physics objects use physics material that determines its behavior, like friction, there's also resting momentum as well. You should start with physics tutorials explaining those things.

[opaque cairn]

hmm. well i have it so that when airborn the physics material switches to a frictionless version.

i've attached a more grounded material as well for the isgrounded state, but that didn't make any changes so i didn't commit to it.

[gleaming kraken]

so rather than

bool targetted = collision.gameObject.GetComponent<Target>().isTarget;
if (!targetted)
{
   // Code
}

it would be more

bool targetted = collision.gameObject.GetComponent<Target>();
if (!targetted.isTarget)
{
   // Code
}

right?

[opaque cairn]

i'll give those tutorials a look t hough

[slender nymph]

well the variable type will need to change. but yes, then in the following lines where you call GetComponent<Target>() again, you would just use your targetted variable instead

[gleaming kraken]

yeah I see, thank you for all the help!

[fickle plume]

Debug that those states clear properly, otherwise it's a matter of configuring physics values like mass and friction to make sense for the current setup.

[opaque cairn]

mass might be one of those elements. I haven't really messed with anything mass i don't think.

[stuck palm]

public void Update()

        var quaternion = transform.localRotation;

    }
``` Like this?

doesn't seem to work for me. looks like it still rotates along its global axis

[slender nymph]

just use transform.Rotate

[stuck palm]

okay, thanks

[graceful walrus]

I am developing something very similar to this, https://pin.it/3kI90Vm07, but I have a concern. In my game the player can use multiple guns, all which could have different height size. When shooting, I want the bullets to move only in the y-plane towards the direction of the mouse. The problem is that the if the bullets come out of the muzzle of the gun, since the position of the muzzle of each gun can be in a different y-position, it makes the bullets not travel parallel to the shooting y-plane. This is because the gun is position so that its handle is set to an offset relative to the player's position. This makes the shooting in my game to not be consistent. How can I avoid this? Am I thinking in the wrong way?

[wintry quarry]

How can I avoid this
Most shooters simply fire the projectile from the center of the camera

to avoid such a problem

Sometimes there's a particle effect that happens at the same time that appears to come from the gun itself

but it's an illusion

Sorry i just looked at the link and saw it's a topdown lol.

Similar things apply though

Are they all raycasts? Or are there slow moving projectiles?

[graceful walrus]

They are raycasts

[rich adder]

You probably want to raycast on a plane unless you need the y to go up and down

even without one , if you're using mouse as target direction you can just keep the Y pos the same height as your weapon/player/firepoint

like mousePosTarget.y = firepont.y , or something. Then calculate the dir

[wintry quarry]

Then just do the raycast always from the same place. The visual projectiles (line renderers, particles, etc) can come from the gun muzzle to the place the raycast hit

[flat tide]

Hey! I have a quick question how can I make a patrolling NPC hold a spot for a few seconds maybe add a animation before moving to the next waypoint?

[rich adder]

@graceful walrus are you trying to do something like this?

[rich adder]

Timer/Coroutine

[flat tide]

could you give me a quick short example? of a timer / coroutine?

So i can base mine on that

[rich adder]

IEnumerator Patrolling(float timeBetweenPatrolPoints)
{
    while (true)
    {
        float t = 0;
        while (t < timeBetweenPatrolPoints)
        {
            t += Time.deltaTime;
            yield return null;
        }
        //go to next point
        yield return null;
    }
}```

ofc its an example, you can always make it randomize time and other stuff, a lot of Coroutine exmaples show the WaitForSeconds class but I personally don't like using it so i just manually do the timer as shown above
btw you can also use Update and use Time.time instead

[graceful walrus]

Yes, but I don't need the y component for the bullets. The shooting should parallel to the y-plane

[rich adder]

oh okay if you want specific height just assign the Y to whatever height you want

or don't rotate the X on the firepoint if you're doing that

you'd have to show more details of setup currently to have more specific

[graceful walrus]

What you have is what I have minus the y component. But my concern is what to do if the guns are of different heights and so the bullets would be traveling in different y-planes, which would mean that the shooting plane changes based on the height of the gun. But this would make the shooting in my game inconsistent

[rich adder]

so don't make the height based on the gun but a specific height you set

[graceful walrus]

I know I could, but then wouldn't this make the bullets travel diagonally towards the mouse instead of horizontally?

Assuming the bullets come from the muzzle of the gun?

[rich adder]

it depends how you are "pushing" the bullets, are they just raycasts? the mouse target y should be the same height as your origin Y pos

[graceful walrus]

If they were raycasts then it would be understandable, but if they were not raycast, how could this be handled?

[rich adder]

keep the two Ys consistent no ?
targetPos.y = firePointOrigin.y var dir = (targetPos - firePointOrigin).normalized

rb.velocity = dir * speed

[graceful walrus]

Hmm, I think I am thinking about it the wrong way. But thank you anyway

[rich adder]

sorry lol maybe show the current code and setup + whats happening right now, could probably be able to better understand the issue

[graceful walrus]

I don't have the code for it just yet, it is just my analysis of the example I showed initially. In that example, their is only one weapon that is aligned with the shooting plane, but if the player was able to use multiple gun's and some of this gun's are bigger(for example, a rifle compared to a pistol), it would mean that the muzzle of the gun is higher and so the player would be shooting at a height depending of the gun's size, which it's not what I want

Hi, you've all probably have heard this a lot, but I'm new to Unity and am just completely new to any kind of programming software. Do you guys have any suggestions as to how to get started in learning how to use Unity and learning how to program? I appreciate any kind of advice! I'm completely new, so I don't know anything. Even a video tutorial that you think is very helpful will be much appreciated.

hello every one i have an array of 6 buttons
and i want to change the position of each one
each time we press one of them but for some reason it show me that i didn't assigne any variables to my buttonsE array

the problem

[rich adder]

why would height change with weapon change? either way you can still make the height of origin a fixed one

They are the same version so sure

[rich adder]

should be seamless its the same editor

oh in that case 2021 should be just fine, depends what types of assets ofc but should be non-issue

[north kiln]

2021, what an edit

[queen adder]

actually we using 2022 lol

[rich adder]

2 year gap

[silk night]

Yeah, did that at work to test performance on the new version for an old project that bitterly needed an upgrade, no real breaking changes but urp custom shaders broke all over the place

[queen adder]

but I have different projects on different versions, soo-

[rich adder]

as long as you got VC test away!

[north kiln]

Yes, we upgraded, yes, there were numerous things that needed fixing

Our URP custom shaders broke too

Our custom shaders broke because the way keywords are resolved changed

We had to declare every keyword we were using in hlsl files at the root of every shader graph

[silk night]

i wish i could write non-shadergraph shaders 😐 another dev had to fix that stuff in the project

[queen adder]

hmm wont you have to redo the shadergraphs?

[silk night]

nah shadergraphs are mostly fine as the nodes update too

[queen adder]

or were you using hlsl? (I suck at both so probably not good idea to do all that myself)

How are you supposed to test a clean save on mobile? It always fetches the previous save data on the phone, and there's no way to clear it out as far as I can tell? My game doesn't have a save slot system or 'new game' option

I tried to use PlayerPref to detect if it's the first time the game has been launched, and clear save data if so, but that only works one time and then it doesn't even work for subsequent builds

[slender nymph]

if you're saving data using playerprefs and want to clear all of the saved data, just make a button that calls PlayerPrefs.DeleteAll

[blissful yew]

Sure but I only want to do that the first time the game is played, and I don't know how to do that

[slender nymph]

well if it's the first time the game is played, then there won't be any saved keys

[blissful yew]

Well I just deleted the game on my phone and rebuilt it and the added playerpref ('GamePlayedBefore') was found.

        {
            Debug.Log("First Time Opened");
            PlayerPrefs.SetInt("FirstTimeOpened", 1);
            PlayerPrefs.Save();
            
            if (Directory.Exists(_playerDataDirectory))
            {
                foreach (var file in Directory.GetFiles(_playerDataDirectory)) File.Delete(file);
                Directory.Delete(_playerDataDirectory);
            }
            FindObjectOfType<LevelManager>(true).ResetAllLevelData();
        }
        else Debug.Log("Has Been Opened Before");```

[slender nymph]

well that's because it's not the first time it's being played. you already saved data. if you want to clear it out for testing, then just make a button that does that

[blissful yew]

yeah that's annoying to have to shoehorn a button in but ok

[slender nymph]

it's either that or you have to do more work by saving the current version number and making sure to increment that version number each time you want to clear it, and also make sure that code is removed for release so you don't fuck over your players for each update. plus having a button would allow your players to delete their own data if they so desired

[blissful yew]

done lol

Hello,

I have a little problem with camera + rigidbody fluidity. I used to use a character controller, but I decided to change it to have a physical interaction with some objects.

However, I can't get the same fluidity I had with the character controller...
I've activated interpolation, set the time step to 0.01, tried to separate my camera from my player, but nothing works...

It's really a problem of fluidity when I move forward at the same time as I turn the camera.

using System;
using UnityEditor;
using UnityEngine;

public class PlayerMove : MonoBehaviour
{
    [SerializeField] private float sensitivity;
    [SerializeField] private GameObject playerCamera;

    private float _xRotation;
    private float _yRotation;

    private Vector3 PlayerMovementInput;
    public Rigidbody _rigidbody;
    public float speed;

    private Vector3 moveVector;
    private void Start()
    {
        _rigidbody.isKinematic = false;
        _rigidbody.freezeRotation = true;
        _rigidbody.interpolation = RigidbodyInterpolation.Interpolate;
    }

    private void Update()
    {
        var mouseY = Input.GetAxis("Mouse Y") * sensitivity;
        var mouseX = Input.GetAxis("Mouse X") * sensitivity;
        
        _xRotation -= mouseY;
        _yRotation += mouseX;

        _xRotation = Mathf.Clamp(_xRotation, -90f, 90f);
        PlayerMovementInput = new Vector3(Input.GetAxis("Horizontal"), 0f, Input.GetAxis("Vertical"));
    }

    private void FixedUpdate()
    {
        MovePlayer();
        RotateCamera();
    }

    private void RotateCamera()
    {
        transform.rotation = Quaternion.Euler(0, _yRotation, 0);
        playerCamera.transform.localRotation = Quaternion.Euler(_xRotation, 0, 0);
    }
    
    private void MovePlayer()
    {
        moveVector = transform.TransformDirection(PlayerMovementInput) * speed;
        _rigidbody.MovePosition(_rigidbody.position + moveVector * Time.fixedDeltaTime);
    }
}

[slender nymph]

you're breaking interpolation by assigning the transform.rotation

[woven otter]

hum

ok, so, i need to use MoveRotation ?

[hexed dove]

hello i am making a finite state machine which depends on a tickManager. I want my states to change every tick. But currently, it doesn't work because it doesn't detect the boolean to true.

thank you for taking some of your time...

[polar acorn]

What do you mean by "Doesn't detect the boolean to true"

This is a lot of code to comb through for a "doesn't work" check, what's the specific problem? Which code is doing something you don't expect? What should it be doing instead?

[slender nymph]

MoveRotation may not be what you want, it likely won't feel very satisfying for players since it moves it to the desired rotation over time to the next physics update. you could probably get away with assigning the rigidbody.rotation, but i also recommend switching to cinemachine for the camera logic

[hexed dove]

So, I have a condition in my idle and move state wich make the state transition. I would like the state machine to change state every tick of my tickManager which speed can change

But currently it just doens’t detect the OnTick bool in the tickManager because it changes too fast from true to false

    // Combine both controller inputs to create movement direction
    Vector3 movement = new Vector3(leftInput.x + rightInput.x, 0, leftInput.y + rightInput.y) * movementSpeed * Time.deltaTime;

    // Move the player in the direction of the joystick input
    transform.Translate(movement);

    // Optionally, rotate the player body based on input
    if (leftInput.x != 0 || rightInput.x != 0)
    {
        // Rotate based on joystick movement (left or right)
        float turnAmount = (leftInput.x + rightInput.x) * movementSpeed * Time.deltaTime;
        playerBody.Rotate(0, turnAmount, 0);
    }
}

It does on VR

And developing a gorilla tag fan game

That is the player movement

Well, I'd wrap it in an if and then go from there

Hi, I am making a top down table tennis game and I use animationCurves to simulate the bouncing of the ball on the table. Everything was working fine until I added the check if the ball executed keyframe 3 of its animationCurve within the trigger area of the table, to credit points differently to each player. Now it doesn't work anymore, the animationCurve is not executed, the ServeMode is not activated either, the only thing that works are the physics between the players and the ball. script: https://hatebin.com/bkhoqnwfgc

Sorry I'm not sure which channel to ask this in but the localization package is making my project stuck on importing assets when playtesting

I'm trying to use Localized Sprite Event

it just doesnt work

[ember tangle]

I'm trying to pass a function as an argument but I cant get it to work, I tried using System.Action and using System.Action<>; like stack overflow said but it didn't work.

here is the function:

    {
        pointer = new PointerEventData(eventSystem);
        pointer.position = Input.mousePosition;

        //Create a list of Raycast Results
        List<RaycastResult> results = new List<RaycastResult>();

        //Raycast using the Graphics Raycaster and mouse click position
        raycaster.Raycast(pointer, results);

        //For every result returned, output the name of the GameObject on the Canvas hit by the Ray
        foreach (var result in results)
        {
            if (result.gameObject.CompareTag("ItemPane"))
            {
                function(result.gameObject);
            }
        }
    }```

[rich adder]

what are you trying to do with the function? there are multiple syntax errors here

[ember tangle]

This code gets repeated across 5 functions in almost the same manner and I though that instead I just call the InteractWithItemPane() and pass the relevant function in.

[cosmic dagger]

Func<> returns a value . . .

[ember tangle]

ie ```public void UIOnMouseDoubleClick()
{
pointer = new PointerEventData(eventSystem);
pointer.position = Input.mousePosition;

//Create a list of Raycast Results
List<RaycastResult> results = new List<RaycastResult>();

//Raycast using the Graphics Raycaster and mouse click position
raycaster.Raycast(pointer, results);

//For every result returned, output the name of the GameObject on the Canvas hit by the Ray
foreach (var result in results)
{
    if (result.gameObject.CompareTag("ItemPane"))
    {
        inventory.UseItemPane(result.gameObject);
    }
}

}```

[rich adder]

but you're not passing the function anywhere

oh I see what you want to do..

[ember tangle]

My end goal is to have something like InteractWithItemPane(SingleClick()) InteractWithItemPane(DoubleClick()) InteractWithItemPane(MouseUp()) etc

[rich adder]

when you pass function you don't add the ()

() is for calling

[cosmic dagger]

it's prolly just a syntax issue . . .

[ember tangle]

its a delegate right?

[cosmic dagger]

() is the invocation . . .

[obtuse quarry]

I'm wondering if this pathfinding algorithm is good

So theres obviously a cell grid, theres a moving node (you) and the target node (destination)

You check all open nodes in each cardinal direction from the moving node whos closest to the target node, and move the moving node there

And continue until you reach the target node

Is this a good pathfinding algorithm? and is there already a name for this? Its the simplest (i think) so I'm assuming its known

[rich adder]

they have so many

Dijkstra, A* etc.

[obtuse quarry]

Is the one im describing still good even if its simple?

Or should I like... not use this one

Hey all, I'm trying to get my cinemachine virtual camera to rotate the character body but it doesn't seem to work as simply as I thought it'd be. What's the alternative method to this?

[ivory bobcat]

Place a log before and after the rotation to see if the values are what you think they are.

[bold thicket]

They're pretty random values, I don't know how to make sense of it.

However, it seems the values change significantly when I move around rather than when I turn the camera which is weird?

[queen adder]

Idk but maybe the cause is world coordination. Try making body child of camera.

And change localRotation

[bold thicket]

like this?

still doesn't want to rotate 😦

[queen adder]

Have you changed rotation to localRotation of body?

[bold thicket]

    public void cameraMovement()
    {
        
        target.localRotation = vcam.transform.localRotation;
        
    }

should it be like that or target.rotation = vcam.transform.localrotation?

sorry i haven't quite got a handle on local vs global yet

[queen adder]

Me too. Target.localRotation = vcam.transform.rotation

Im not advanced btw

[bold thicket]

doesn't want to rotate 😦

wait i don't think Cinemachines input provider when used for camera movement actually rotates the camera

because as i move it in game scene, the inspector rotation values stay 0

@astral falcon

Sorry for the ping

[astral falcon]

yeh, please dont do that

[astral falcon]

So, when is the code happening, thats not working as intended? whats the trace and how does it behave

[buoyant finch]

Like when an attack is performed the health ui should update with the filled image function

[astral falcon]

Whats the function that should do this?

[umbral bough]

Hi, not sure if this is a right channel to post this q, but yeah, let me know if I should move it.
Would it be possible to get a system font, say by a name(should be possible w c# if I am not mistaken), somehow feed it to the tmp font asset creator, and spit out a usable font at runtime?
I don't need any code examples or anything, just your opinions on if it's is possible or not.

[buoyant finch]

SetHp

[umbral bough]

Also twentacle, I said that I was gonna let you know if I fixed the issue, I have thanks to this server: #1306527853982253079
Thanks again for your previous help!

[languid spire]

Apparently you can

[queen wren]

For some reason VS didn't know that Unity's method like Awake, Update, OnCollider and so on will gets called by Unity, and mark them as Unused.

I've regenerate the project files a couple of times but it's useless.
Any advice to fix it?

[queen adder]

Unity pcg

[queen wren]

Wut?

[languid spire]

screenshot your whole ide window

[teal viper]

I think it's an issue with the latest VS patch.
Might be that the unity vs support package needs updating.

[queen wren]

it's not "that big" issue just a little bit annoying. 😁

[queen wren]

Yeah probably it's about Unity 6 and the lastest VS update.

[teal viper]

I'd check the package manager for updates to the related package.

[queen wren]

under "Get Tools and Features" there's no updates also in Package Manager, but It's a matter of time I guess.

[teal viper]

In unity package manager...

[queen wren]

Yea, nope 😁👍
I'll try to delete all the useless Unity's file, and reimport the project from scratch

[teal viper]

What version is the package?

[obtuse quarry]

is coding your own pathfinding system considered "beginner"?

im having a hard time with doing it

[teal viper]

No, I wouldn't say it is.

It can get pretty advanced depending on what you're trying to do.

[obtuse quarry]

i thought it was gonna be easier than this

but i might be close to finishing it

im not sure yet

[teal viper]

Sounds contradictory

[obtuse quarry]

im still not sure how "good" the way im doing pathfinding is

its simple, i just set the position of the pathfinder to the neighbour who has the cheapest fcost

it sorta works

i mean it works amazing when there are no obstacles

goes to show that "simple" doesnt mean "good"

okay i think this part of my code is failing:

public List<Cell> GetNeighbouringCells() {
        List<Cell> ret = new List<Cell>();
        foreach (Cell cell in cells) {
            if (cell.transform.position == transform.position) continue;
            if (!cell.blocked) continue;
            if (Vector3.Distance(cell.transform.position, transform.position) > 1.5f) continue;
            cell.G = (int)(Vector3.Distance(cell.transform.position, transform.position) * 10);
            cell.H = (int)(Vector3.Distance(cell.transform.position, destination.position) * 10);
            cell.transform.name = $"{cell.F}";
            ret.Add(cell);
        }
        return ret;
    }```

oh i think i found the issue

yay i found the issue, and have successfully moved back to my original code

i just have to fix when it doesnt work around obstacles

[weak cedar]

Yes it is

The c# extension is broken, I reverted to the last update because of that

[hexed terrace]

There's a workaround posted here:
https://developercommunity.visualstudio.com/t/Private-Unity-messages-incorrectly-marke/10779025

[bright siren]

noticed this - at least it is a recognised bug, but seems MS often miss things with the plugin

[hexed terrace]

It's a VS update issue, not so much the VS Unity package... they probably don't test VS updates with Unity things?

[vague adder]

whats wrong? the instructor in the course wrote the same thing with no trouble

[hexed terrace]

maybe finish typing the method and see?

[vague adder]

doesnt log

[devout flume]

Never look at errors while in the process of writing code. Your code was parsed and it just found an unfinished method because you didn't finish writing it

[vague adder]

i usually mind the errors while writing but the tooltip for OnTriggerEnter didnt pop up while writing (even though it popped up in the course) so i got suspicious

[languid spire]

Course probably not using VS Code so dont expect exactly the same behaviour

[burnt vapor]

I suggest you switch to VS or Rider if VSCode can't autocomplete methods

[vague adder]

oh i didnt realise that

[burnt vapor]

This method should just have to be manually typed out

Especially since it's very specific

[vague adder]

i feel like it would take a lot of effort to switch apps

i was told that vs code is like the best

[burnt vapor]

You were probably told by somebody who has literally only used VSCode

Try VS or Rider and you will quickly figure out that this is likely the case

VSCode is the worst one. It's a nice general text editor but not a proper IDE for C# or Unity

[vague adder]

alright ill switch to VS

thanks

https://pastebin.com/ELLASPuY : Cube Code.
https://pastebin.com/xFWkmjmz : TickManager Code.

Hello, i am trying to make a cube rolling game. For that, i made a tickmanager that sends an event each tick to the cube. On each tick, the cube changes state. I have an issue when the cube goes on a conveyor, i would like it to stop after hitting the ground again. i can't manage to do it. With all of what i tried, the cube just bugs out...

If you need more information just ask !
thank you for taking some of your time

[rocky canyon]

what do you mean by "bugs out"
whats happening as opposed to whats supposed to happen?
can u clarify a bit

[hexed dove]

either the cube teleports to the next conveyor destination, either he just teleports back to the acutal conveyor

i tried casting a raycast inside of the DoActionConveyorMove() to see if it hits any conveyor but it doesn't seem to work

[solar torrent]

UnityException: Transform child out of bounds
UnitSelectionManager.TriggerSelectionIndicator (UnityEngine.GameObject unit, System.Boolean isVisible) (at Assets/UnitSelectionManager.cs:128)
UnitSelectionManager.SelectByClicking (UnityEngine.GameObject unit) (at Assets/UnitSelectionManager.cs:117)
UnitSelectionManager.Update () (at Assets/UnitSelectionManager.cs:53)

idk what i did wrong

[gleaming kraken]

the code behind my game is so messy but it works. I need to fix that mentality and actually refactor it but refactoring is incredibly boring. Any tips on making refactoring a little more entertaining, or do I just have to bite the bullet here?

[burnt vapor]

The transform child out of bounds

The stacktrace has been so nice as to tell you where it happened. If you want help here I suggest you share the relevant !code inside UnitSelectionManager.cs.

yea homie imma honest idk what that means i assigend the child to the index of 1

ne of 0

[burnt vapor]

Can't say much without your code

Apart from the obvious

[hexed dove]

can anyone help with my issue pls ?

[solar torrent]

https://hatebin.com/ogmntahjtw

i think it works

[solar torrent]

did it works

[burnt vapor]

Yes, thank you

[solar torrent]

ok

[burnt vapor]

So, do you understand the concept of stacktraces?

[solar torrent]

erm no like a stack as in a paramater

[burnt vapor]

From the bottom up it explains how it took the steps until the exception

So the last call before it broke was in Assets/UnitSelectionManager.cs:128

[solar torrent]

exception as in error?

[burnt vapor]

Yes

[solar torrent]

erm so i clicked than it like broke

[burnt vapor]

In your case this line is unit.transform.GetChild(0).gameObject.SetActive(isVisible);

[solar torrent]

after like a few clicks

[burnt vapor]

Okay, so now you see the docs https://docs.unity3d.com/ScriptReference/Transform.GetChild.html

If the transform has no child, or the index argument has a value greater than the number of children then an error will be generated. In this case "Transform child out of bounds" error will be given. The number of children can be provided by childCount.

So one thing you can do is check if there's at least 1 child with childCount

But in your case there should always be a child I assume?

[solar torrent]

but there is only 1

so i said 0

[burnt vapor]

That's correct

But somehow the gameobject ends up with no child

If I were you, I would start logging the gameobject that comes in.

    private void TriggerSelectionIndicator(GameObject unit, bool isVisible)
    {
        Debug.Log($"TriggerSelectionIndicator: {unit.childCount}", unit);
        unit.transform.GetChild(0).gameObject.SetActive(isVisible);
    }

Then, when the exception is thrown you press the log message that is logged in the console

When pressed, it navigates to the gameobject that was passed

Take a look and you will see it has no children inside

[solar torrent]

wait so

wait wait wait i looked but the child nevers goes away when i press play

[burnt vapor]

It's not supposed to go away, is it?

Don't debug by looking, debug with proof

Your proof is that log message that validates that it's actually using your gameobject

I updated the log message, use that instead

[solar torrent]

the child should uncheck after i unselect and that works but it just randomly bearks

breaks

[vague adder]

thank you 🙏

its so good

it took me just 10 seconds to realise how good the tooltip is

[solar torrent]

do you understand

[silk night]

Wait until you dipped your toes into what rider assistant / github copilot offers you 😄 sometimes i feel like copilot is the only one that really understands me 😭 (/jk)

[vague adder]

is github copilot free

the ''copilot'' word is enough for me to fall inlove with it

[rocky canyon]

theres free ones out there. not sure about copilot.. i would assume its a free feature.. i use vscode and codeium..

theres something so helpful about being about to type out my variables and method names and have my assistant be like:
"oh, i see what ur trying to do here, let me save u some trouble and type out the basic boilerplate for ya"

[silk night]

copilot has a 30day free demo

[rocky canyon]

there ya are ^

[vague adder]

30d aint enough allat

[vague adder]

🤤

[silk night]

its $10 per month after

[rocky canyon]

it defaults everything to debug.log as of now. b/c thats what ive been doing lately..
but back when i was dealing w/ rigidbodies it was completing that.. and same w/ others

in love ❤️ lol

[silk night]

sometimes it does really neat things (only typed the function name here)

[rocky canyon]

exactly!

[silk night]

other times... it does this

[rocky canyon]

sooo good

[rocky canyon]

rofl!! i never had it do that to me yet

pretty good about making lists and arrays

[timber tide]

I don't mind hint/suggestions but auto complete will usually add exactly what I didnt want then proceed to add the namespace I have to clean up later

[naive pawn]

give me a sec while i wallrunjumpclimbsprint

[rocky canyon]

tbh i havent had the best of luck using context..

like supposedly i can ask it a question and add my line number..

but most times it gets all generic on me..

[silk night]

oh copilots context chat is really good

[rocky canyon]

i bet.. 😭 lol. that pay to win

[silk night]

found some really nasty to debug bugs by just asking copilot what it thinks could be an error source

company pays 😄

[timber tide]

most useful thing that I found using it is formatting enums into bit flags

[minor hull]

Just starting out on Unity, I added controller movement to my player character script, but it seems to have disabled my normal keyboard movement. What can I do to fix it?

[silk night]

how did you add it?

[rocky canyon]

imo, this is the best feature AI has to offer.. Formatting and Refactoring

[minor hull]

InputAction and then bound it to the left stick

[steep rose]

it writing code for you though is horrid

maybe for refactoring

[silk night]

Well, thats what it should do, take tedious tasks from us, sometimes that is writing simple functions tho 😄

[rocky canyon]

do you have the new input system set as the default input method?

[minor hull]

There's a default input method?

[steep rose]

Old input system

for unity 6 it might be the new one

[silk night]

nah, id say copilot does some really neat stuff if it has enough context, ofcourse it cant write the base logic 😄

[minor hull]

It's worth noting that I'm following one of the unity tutorials for a 2D adventure game

[steep rose]

use google

[steep rose]

yes use gogle, as gogle is the best search engine

[rocky canyon]

Active Input Handling

[timber tide]

stackoverflow about to become deprecated with the partnership with openAI. Is true through. Why would you want to continue using it nowadays if they're just going to sell your data haha

[silk night]

oh i wont let it write stuff that i dont understand, but ill gladly accept if it saves me 30s to type out a function 😄

[minor hull]

I'm pretty sure I'm using the new input system

[rocky canyon]

you mentioned the action map.. thast what that is .. hte new one

[steep rose]

yeah for just writing functions and refactoring its neat

[rocky canyon]

if its set to "Old" it wont work.. so use the new one or both

[minor hull]

This is what I have atm

[silk night]

thats why i see it as 2edged sword for beginners, if you dont know if the AI is doing good or bad stuff things go sideways rather quick 😄

[rocky canyon]

gotta give it the stank eye when you see it start to wander off the beaten path 😄

[silk night]

did you add another layout for the controller or did you add the controller input to your existing actions?

[minor hull]

Existing actions... I think

[silk night]

uhh what the hell is that 😄 can you show us your inputactions? should be in the project settings

[silk night]

you are settings the new position of the keys and then immediately override it with the controller value (which is 0 at that time)

check if the move vector is != zero

or add the move values together (+ normalize them so you are not double as fast if both go right for example)

[minor hull]

I'm looking for these, but I can't find them in the project settings

[silk night]

mhh then first you should solve what i wrote above 😄

[steep rose]

you would only use AI if at all (which I do not) as another hand to write simple things, nothing else as it is horrible with writing functioning code

I mean it can do it but 😬

[rocky canyon]

did you generate a c# class?

[naive pawn]

it can write functioning code.. just that you don't know what function it'll have

[rocky canyon]

should create a class you can use for ur inputs

[silk night]

If i see it right from his screenshot he is not even using an input asset, just straight up actions on his script 😄

[rocky canyon]

i seen that.. i've never seen it slapped into a class like that..

[steep rose]

yeah that's why its terrible, it also teaches you very bad habits like using find a thousand times 🥲

[silk night]

me neither, but seems to work somehow 😄 ¯_(ツ)_/¯

[rocky canyon]

i thought there was two ways to do it..

1. you generate the c# class and use that
2. you use the player input component

[steep rose]

it hurts seeing it happen

[minor hull]

This is basically day 2 of gamedev with no coding experience, so I don't really know what the best methods are

I'm following a tutorial by unity right now, and these were the steps it gave me

[rocky canyon]

well props to you for starting w/ the new input system

[minor hull]

I'm sure I'll figure out more efficient methods as I keep learning

[minor hull]

I think I did this?
Whatever I did it worked so thanks

[steep rose]

if he is using unity 6 it should be the default selected

[vague adder]

damn

[silk night]

i dont recommend learning the old input system when starting out with unity, it has gotten easier and its way more flexible

the only other package that they should finally include by default is Cinemachine

[vague adder]

Damn

[rocky canyon]

theres also a input debugger in the Window > Analysis menu

might be helpful when learning/ playing around w/ the new input system

[minor hull]

Great, thanks!

where are you homie

[burnt vapor]

You were talking to me

I told you to debug the issue. Did you debug it?

[strong wren]

Ask a question if you have one

[solar torrent]

yea

i did

[burnt vapor]

Show me the console when the exception happens

[solar torrent]

it does not tell anything

[burnt vapor]

Except it will

[solar torrent]

ok should i cann you then bc i cant send the video

[burnt vapor]

Share a screenshot

Full console, with the exception and the last log message
