wrong return type, it should return IEnumerator not IEnumerable

[summer pilot]

hey im having a problem:

1. my game loads
2. i press play
3. my game starts normal
4. i press e to open my menu temporary keybind
5. my game pauses and shows me the menu
6. i press the menu button to go BACK to my menu
7. i once again press the play button
8. my game starts, but is paused

• in order to unpause i need to press the e button again

im not sure what i need to provide to get help with this, please let me know

in the meantime I can provide a couple screenshots of the .cs files related to this

StartMenu.cs

PauseMenu.cs

[slender nymph]

sounds like you're setting the timescale to 0 when you open your pause menu, but aren't setting it back to 1 to close it

[summer pilot]

i might not be, but i really think i am setting it back

[dry spruce]

can u guide me more i am a newbie

[slender nymph]

read the page i linked

[slender nymph]

before you can get any help, you need to configure your !IDE

[eternal falcon]

💡 IDE Configuration

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

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[summer pilot]

i downloaded the .cs and the unity extensions

downloaded and installed*

[slender nymph]

you've missed a step since you do not appear to have syntax highlighting for unity types

[summer pilot]

idk man it seems fine??

im looking at the thing you send and everything is adding up

[slender nymph]

regenerate project files and restart vs code.

[summer pilot]

C# and Unity are installed

[summer pilot]

doing this rn

[slender nymph]

and if you've never installed the .net sdk (such as through the c# dev kit extension) then you need to do that. and restart your computer

[summer pilot]

where do i get that

is this it?

[slender nymph]

obviously yes, it's literally telling you what isn't installed and happens to be called exactly the same thing i said you need to have installed

[summer pilot]

don't need to get smart about it man, it wasn't showing this before i reloaded unity and vscode, i was just double checking man

[slender nymph]

i told you specifically you'd need the .net sdk. you now see vs code complaining that you need the .net sdk and giving you a link to download the .net sdk. please put some thought into this

[winter tinsel]

how can i hide the box collider in game mode?

nvm im stupid

[slender nymph]

depends on your definition of "hide" in this context

[winter tinsel]

i had the object selected thats why it showed its collider

[slender nymph]

ah, for the record gizmos are an editor-only thing. you wouldn't have seen that in a build regardless

[summer pilot]

its installed, no error
doesn't really look any different than before

[slender nymph]

did you restart your computer

[summer pilot]

ah, ill do that

[summer pilot]

restarted, still looks the same
not seeing any underlined issues

[slender nymph]

it obviously does not look the same because now you've got syntax highlighting for unity types

[slender nymph]

if a parent object has a rigidbody then this collider will be considered part of it, so you need to either mark the collider as Convex, make the rb kinematic, or disconnect this object from the rigidbody

[summer pilot]

the difference in these images (to me) is some color changes and the dimming of the top 2 lines since I did not use those systems in that script.

if i am missing something obvious please let me know

[slender nymph]

yes, the correct syntax highlighting is the difference.

[summer pilot]

alright then

[slender nymph]

nobody said that there would be any red underlines appearing in this code. it is just a requirement to have a configured IDE to get help with your code here
#854851968446365696

[summer pilot]

my bad, i read that in your message and thought that might've been something i was looking for

now that my IDE is setup do you need new screenshots of those two scripts?

[slender nymph]

no, you should share your !code correctly for help. but you also need to make sure you are actually calling that Resume method and not just disabling your menu or whatever

[summer pilot]

resume is being called @ line 18

[slender nymph]

now make sure it is actually being called

[timber comet]

Put some debug.log inside your if statement, and see if it is being called

[summer pilot]

thats what im doing rn

[slender nymph]

i'll give you a hint as to what is happening: Resume is not being called by the button you close your menu with

[summer pilot]

its also not doing it when pressing the keybind either :/

but i dont see how that can be

because the timescale and cursor part of resume is working

also the toggling of the canvas works

waiiiit

line 19 does NOT get called, but line 34 DOES

so it is being called

[slender nymph]

that would mean that something else is calling that method

[summer pilot]

something else?

[slender nymph]

yes, like a button. not code, otherwise you'd see more than just 1 reference for the method

but if you confirmed that Resume is being called then you need to be more descriptive about what exactly is happening when you resume from the menu. or show a video

[summer pilot]

no other button is using PauseMenu.Resume

[summer pilot]

ok i will give you a video

[slender nymph]

how have you confirmed this

[summer pilot]

i looked @ all my buttons?

i dont have that many

[slender nymph]

well something is calling it if you get that log but not the other one. it may not necessarily be a button, that was just a suggestion

[summer pilot]

here you go

[slender nymph]

so the issue has been happening when you go back to the StartScreen scene from the pause menu? please make that clearer next time. you're using two separate GameIsPaused bools that have nothing at all to do with each other

why are you setting the game as paused when you go to the StartScreen scene anyway?

[summer pilot]

i said this in my original message

[summer pilot]

im setting it as not paused when going to the start screen

the only time its pausing is when the pause menu is opened

wait

[slender nymph]

you said i press the menu button to go BACK to my menu which did not make it clear you were changing scenes

[summer pilot]

my bad then

[summer pilot]

i see the line, i meant for it to be false

wait no i didnt

i see why i did that

one sec

if i don't pause the game, my cursor is locked to the screen as if i am playing it. i don't have access so i can select an option

[slender nymph]

you know there's a simple line of code you can run to fix that, right? look very closely at how your Resume method works, then look at what you are doing differently in the LoadStartScreen method. also for the love of god stop showing off your code in video form

[summer pilot]

sorry abt the code thing, its a bad habit of mine from doing .js stuff

    public void LoadStartScreen()
    {
        Time.timeScale = 1f;
        GameIsPaused = false; //this is now false instead of true
        Cursor.visible = true;
        Cursor.lockState = CursorLockMode.Confined;
        SceneManager.LoadScene("StartScreen");
    }

is this what you're talking about with how it was different? this is what it looks like after i changed it

[slender nymph]

does it work now? also you could literally just call Resume from LoadStartScreen instead of copy/pasting all of that

[summer pilot]

no, it doesn't work now

the cursor doesnt even show still

[slender nymph]

you have saved the code, right?

[summer pilot]

yes i have

[slender nymph]

show the inspector for that menu button

[slender nymph]

ah wait, your resume hides the cursor. that's my bad, you'll need to make sure you're still manually releasing the cursor

[summer pilot]

that's not an issue here, i still didnt swap the resume over to the loadstartscreen

    public void LoadStartScreen()
    {
        Time.timeScale = 1f;
        GameIsPaused = false; //this is now false instead of true
        Cursor.visible = true;
        Cursor.lockState = CursorLockMode.Confined;
        SceneManager.LoadScene("StartScreen");
    }

this is still what is being loaded

[slender nymph]

then either you've got other code hiding the cursor or this method is not being executed. or it hasn't been saved.

[summer pilot]

this is the only other script i have

            {

                walkSpeed = crouchSpeed;
                runSpeed = crouchSpeed;

            }
            else
            {
                characterController.height = defaultHeight;
                walkSpeed = 6f;
                runSpeed = 12f;
            }

            characterController.Move(moveDirection * Time.deltaTime);

            if (canMove)
            {
                rotationX += -Input.GetAxis("Mouse Y") * lookSpeed;
                rotationX = Mathf.Clamp(rotationX, -lookXLimit, lookXLimit);
                playerCamera.transform.localRotation = Quaternion.Euler(rotationX, 0, 0);
                transform.rotation *= Quaternion.Euler(0, Input.GetAxis("Mouse X") * lookSpeed, 0);
            }
        }
    }
}

which hides the cursor when the game is not paused

he told me to use the blocks

[slender nymph]

no i didn't, i asked you to post your code correctly. which the bot shows you how to do

[summer pilot]

jesus my brain is fked

im so sorry

im gonna try something else

if i add another public bool named PlayingGame

i can set if the player is playing seperate to if the game is paused

so then in player movement i don't need to check if the game is paused, i just need to check if the player is moving

or is that stupid?

[sharp abyss]

How can I make my character walk like the games "daddy long legs" or "steppy pants" by pressing buttons and moving legs separately.I can lift the leg but cant make it go forward when I stop pressing button and should I use limits on hingejoints?

I added force when I getkeyup hope that works

[winter tinsel]

first if statement works, the debug tells me it reaches 50, but the second if statement never fires, even outside of the spawntime if

why??

its inside update()

[slender nymph]

you're checking if it is greater than 50. it can never be greater than 50 if you only increment it when it is less than 50

[dapper sparrow]

put >= in the second if statement i think

[winter tinsel]

yeah that was it

[slender nymph]

i do want to note that if this code is inside of Update then this will be faster with higher framerates

[frank zodiac]

is there an AND OR operator in c#?

[teal viper]

I want to see a programing language that doesn't 🤔

[slender nymph]

am i crazy or does AND OR just not make any sense? there's definitely the AND operator, and the OR operator, and XOR, but what the hell would an AND OR operator do? because if it requires both to be true, that's just the and operator, and if it only requires one of the two to be true, that's just the or operator

[honest salmon]

I think he means 1 and 2 are true or 3 is true, but idk 🤷‍♂️

[frank zodiac]

XOR??

is that the and or?

[slender nymph]

that's exclusive or. again, what the hell do you think AND OR is supposed to do?

[slender nymph]

that's just two separate checks though with two different operators

[frank zodiac]

Yeah now that I think about it, its pretty much the same as OR

Also how do I generate a random integer? it only gives me float values as parameters

[slender nymph]

did you look at the docs

[frank zodiac]

Nope

[slender nymph]

well it's no wonder you didn't find anything helpful

[honest salmon]

int randomInt = Random.Range(0, 100);

[frank zodiac]

thanks i found out now that it has an int overload

[summer shard]

How can i get the next value of a dictionary based on current key

[slender nymph]

dictionary keys are arbitrary, there is no "next" key. at best you can foreach over the dictionary but that doesn't sound like what you want

[summer shard]

hmm, this is what i have rn and i want to get the next "objective"

public void completeObjective(Objective objective)
{
    if (currentObjective != objective) return;

    Objective nextObjective; // ???
    currentObjective = objective;
}

private void Start()
{
    foreach (Objective objective in GameObject.FindObjectsByType<Objective>(FindObjectsSortMode.None))
    {
        objectives.Add(objective.id, objective);
    }

    if (objectives.Count <= 0) return;
    objectives = objectives.OrderBy(obj => obj.Key).ToDictionary(obj => obj.Key, obj => obj.Value);
}

[slender nymph]

dictionaries are not ordered and the keys are arbitrary. "next" in your mind might not be "next" in the dictionary

use a list or array and just keep the current index then you can just ++ that index to get the "next" one

[summer shard]

but can i sort them by objective.id ?

[slender nymph]

sure, why not?

[summer shard]

i thought you can't sort lists??

[slender nymph]

why would you think that? there's literally a List.Sort method

[summer shard]

OHHH, i didn't see that, thanks

[broken cargo]

Are ids consecutive? you might be able to just increment the id and find objective in dictionary

[vast vessel]

is this a good way to calculate falloff with a min and max distance? (im going to use this for my AI hearing sensors)

[summer shard]

i'm trying to make them but they're not always one after another

[broken cargo]

Then you'll need another list of Ids to keep track of the order

[summer shard]

wouldn't this just work??

private void Start()
{
    foreach (Objective objective in GameObject.FindObjectsByType<Objective>(FindObjectsSortMode.None))
    {
        objectives.Add(objective);
    }

    if (objectives.Count <= 0) return;
    objectives.Sort((o1,o2)=>o1.id.CompareTo(o2.id));
}

[broken cargo]

Yes, this will get you a list of objectives ordered by id

[summer shard]

okayy, thanks

[silk night]

I think sound sources have a falloff curve built in, or do you need the raw value for something else?

[vast vessel]

i wanted linear fall off and didnt want to have to set up curves for each sound, in the editor, so i ended up using mathf.lerp.

evaluating a curve would probably have a higher impact on the performance so i dont think its worth it

[queen adder]

I couldn't find an answer anywhere online but, Is it possible to use LUA in unity? Trying to transfer softwares but I only breifly understand other programming languages.

[slender nymph]

there are probably assets/packages that allow you to include lua scripting for within your game. but unity's scripting language is c# so you will need to learn c# if you want to make a game in unity

[queen adder]

Alright, I figured i probably would have to. Thank you.

[slender nymph]

there are beginner c# courses pinned in this channel to help you get started

[wintry quarry]

With MoonSharp https://www.moonsharp.org/

but no you're not going to be able to just dump Roblox code into Unity.

[naive locust]

damn

[slender nymph]

doesn't this still require using c# to interact with the LUA code?

[naive locust]

is there any issue with detecting inputs like this?
when i use just "Input" it comes up with an error

[slender nymph]

you probably have your own class called Input

[wintry quarry]

yes

[wintry quarry]

Comes up with what error?

Just saying "an error" isn't very specific

[naive locust]

oh mb lemme run it

[fierce geode]

Hey, Don't know if this is an important enough question.
But where should the responsibility lie in two objects when they interact to who executes the code. Like on a simple level, when an enemy damages the player; to which should the deal damage code be placed. Should the code for dealing damage be placed in the enemy's script or should the player script have the code for taking damage?

Does it matter? Is there some kind of design methodology to follow or is it just semantics?

[wintry quarry]

both usually

[wintry quarry]

get rid of using UnityEngine.Windows; at the top of your script

[slender nymph]

ah, you probably don't need that UnityEngine.Windows namespace imported
https://unity.huh.how/compiler-errors/cs0104

[naive locust]

ohhh ok

ty

[frosty hound]

The player ultimately handles its own HP, so it should have its own methods for adding/removing it.

The enemy decides on what it hits, and then notifies that thing that it hit it. It can be the player, or whatever else your game may allow enemies to hit.

[slender nymph]

separate dealing damage from taking damage. the responsibility of dealing the damage should be on whatever is actually causing the damage. then whatever is receiving the damage can have some specific component (or an interface) for receiving that damage. that way neither object needs to specifically know about the other, the damage dealer just looks for that damage taker component and applies the damage

[queen adder]

Didnt even know roblox used LUA lmao. Learn something new every day.

[fierce geode]

Thanks 👍

[wintry quarry]

Really if you want to learn Unity you should learn C#.

there's no replacement for that

[fierce geode]

UnityScript 😏

[eager spindle]

in 2024 😨

[atomic holly]

Hello !
I want to use an extern collider of my script and verify if this collider is touching and other collider wiht the tag "Enemy". Can I use a OnCollisionEnter2D or not ?

[slender nymph]

OnCollisionEnter2D would only be called on the object that has the collider or its rigidbody parent (if it has one). if your component is not attached to that same object then it will not receive the OnCollisionEnter2D message for that collider

if you explain your actual use case, a better solution can be suggested

[atomic holly]

I don't want to use a collider of the object himself but a collider of his children

[wintry quarry]

that will work fine as long as the parent has a Rigidbody2D

[atomic holly]

Yes the parent have a RigidBody2D but what function I use if I can't use OnColliisionEnter2D because it's not the collider of the gameobject himself ?

[slender nymph]

if the component is on the same object as the Rigidbody2D then it will receive the OnCollision message

[wintry quarry]

You can use OnCollisionEnter2D

[atomic holly]

Yes but I don't want the verification of the 2 collider but only the child

[slender nymph]

well you've still not bothered saying what any of this is for so 🤷‍♂️

[wintry quarry]

Note that Collision2D tells you which colliders were involved

So you can always check in your code if it's the appropriate collider

[atomic holly]

I have weapon that's a child of my player. This weapon have a collider and I want to verifiy if the collider of the weapon touch an enemy, it do a function.

But the script PlayerDamage is in the Player gameObject

So, I integrate the collider of the weapon in the script like this

[slender nymph]

well like Praetor pointed out, the Collision2D parameter of the OnCollisionEnter2D method will provide information about the colliders involved in the collision.
although i personally would either disconnect the weapon from the player entirely and give it its own component or use physics queries

[atomic holly]

Why u would disconnect the weapon of the player ?

[slender nymph]

is there a specific need for it to be a child? if the only need for being a child is following the player, there are plenty of options for doing so without being a child

[wintry quarry]

For detecting attacks, physics queries are usually the way to go

unless this is some kind of active ragoll QWOP style game

[atomic holly]

Okay. For me, if the weapon is a part of the player, it needs to be a child of the object

[atomic holly]

What is QWOP ?

[wintry quarry]

https://www.foddy.net/Athletics.html

[slender nymph]

okay, nobody said you had to remove it from the player. it was simply a suggestion of how i would handle it if i weren't using physics queries for its hit detection

[atomic holly]

Oh sorry, i don't want to be agressive at all; I just wanted to know why you think like this

I'm not very fluent in English it's maybe why you think i'm little agressive

But I just want to know your process of why you should take the weapon out of the player

[slender nymph]

i told you why . . .

if there is no specific need for it to be a child of the player then i wouldn't make it a child of the player. that's literally it

[atomic holly]

Okay, thanks a lot guys

[balmy grove]

hello

[winter tinsel]

as a prefab it wont let me drag the player into the "target"

what do i do

im guessing tags?

[wintry quarry]

assign the reference at runtime

FindWithTag is one option, sure

Or just having the spawner give the new instance the reference directly

[winter tinsel]

how do i use findwithtag

[wintry quarry]

There is an example in the docs https://docs.unity3d.com/ScriptReference/GameObject.FindWithTag.html

[winter tinsel]

found it

thanks

[atomic holly]

I write this and when I do a left click, the hello is send directly and not 10 seconds after. Did I do something wrong ?

    //Vérifie si le clic gauche est pressé
    if (Input.GetMouseButtonDown(0))
    {
        weaponCollider.enabled = true;
        StartCoroutine(WaitSeconds(2));
        weaponCollider.enabled = false;
        Debug.Log("Hello");
    }
}

private IEnumerator WaitSeconds(float seconds)
{
    yield return new WaitForSeconds(seconds);
}

[wintry quarry]

coroutines cannot delay other code

they only delay themselves

your coroutine here effectively does nothing

You would need to put the log INSIDE the coroutine for it to be delayed:

private IEnumerator WaitSeconds(float seconds)
{
    yield return new WaitForSeconds(seconds);
    Debug.Log("Done waiting");
}```

[atomic holly]

Oh okay, I see

Thanks 👍

[hearty anvil]

Hello everyone, I'm trying to make obstacles move faster as the score increases. After scoring 14/24/34/44/54... points, a larger gap appears between only one set of two obstacles. It wasn't doing this before I added the function to speed up the game.

[wintry quarry]

presumably a bug in your code, but hard to say much without seeing details

[hearty anvil]

would you mind looking it over

[cosmic quail]

you can just post it and someone might look

[summer stump]

Likely you are using time to spawn the obstacles. If they move faster, but only spawn after a set time the gap will increase.

As you increase the speed, decrease the time to spawn.

Just a guess

Ah, missed the part where you said only one set of the two obstacles.
My answer is likely wrong then

[icy grotto]

hi, is there something like this that would check for UI layer?

EventSystem.current.IsPointerOverGameObject

[wintry quarry]

can you explain what you mean by "check for UI layer"? In what context?

[azure hemlock]

why is the picture (heightmap) (dark as u can see) imported as white in unity? how do i turn off this shit?

[silk night]

can you show the result in unity?

[azure hemlock]

its on the right

even when i encode it to a file using c# it gets encoded as the white one unity made.

[silk night]

can you send the heightmap file here? ill try on my own unity

[wintry quarry]

The better approach is to switch to using the event system for your click interactions @icy grotto

[azure hemlock]

here is it

[silk night]

uhh look at the height map in browser like chrome, its white there too

wtf

[azure hemlock]

lol

wtf

makes no sense

[icy grotto]

for some reason this one works, I thought "GameObjects" would include 2D objects, turns out I could still move while pointing over one.

anyway thank you!

[silk night]

check "Ignore PNG gamma"

[naive locust]

what does void mean and what is it used for?

[silk night]

it means no return (or empty return) from that function

[polar acorn]

It means the function does not return a value

[naive locust]

so what would you do if you want a return?

[cosmic quail]

replace void with a type

[polar acorn]

Use the type you want to return

[cosmic quail]

and then at the end you gotta type "return <thing>;"

[azure hemlock]

i just resaved it in another tool and it worked. i guess it had some hidden info within it? gamma ?

[naive locust]

oh so for example

string WriteASentence(sentence)
{
  ...
  return sentence;
}

?

[polar acorn]

Yes, and then you need a return statement with what string you want to return

[frosty hound]

(Which does not have to be at the end, as incorrectly stated above)

You can return out of the function whenever you want. If it's a void return, then you can just return. Otherwise, you have to return something of that type: return "MySentence";

[polar acorn]

Right, it can be used to exit the function early, which can be used for example when you're looking for a specific element in a list. You can return the value before the loop finishes to prevent wasting time checking after it's found

[cosmic quail]

wherever you put it it becomes the end 😄

[frosty hound]

Yes, which is correct when stated correctly like that.

[naive locust]

is there a way to specifically break a loop such as a break function?

[languid spire]

break;

[naive locust]

ok

thx

[quick ruin]

is there a reference to the top face of the box collider?

[wintry quarry]

It only includes things the Event System is aware of which by default is only UI

[icy grotto]

exactly what I need. thanks!

[winter tinsel]

nullrefrenceexception

is it because im deleting it then calling more code from it?

[summer stump]

Gonna guess it is for shippy

Where do you assign shippy?shipping? And is it a child of the gameObject?

[rocky canyon]

u know gameObject is the script the collisionenter is on.. and not the other one right?

ur destroying that script instead of the other object

[wintry quarry]

no it's because you're accessing a null reference, particularly shippy

[winter tinsel]

how is shippy a null refrence tho

[wintry quarry]

you never assigned it

[winter tinsel]

shippy is a script

[wintry quarry]

or you assigned it to null

[rocky canyon]

idk.. why u not assigned it?

[winter tinsel]

im calling a script

[wintry quarry]

it's a variable, which is a reference to an instance of a script

[summer stump]

Where do you assign it?

[winter tinsel]

public shipscript shippy

[wintry quarry]

yes this is a reference variable

which are null by default until you assign them.

[summer stump]

That is a declaration, not assignment

[wintry quarry]

until you assign them.

[winter tinsel]

how do i assign them?

[wintry quarry]

with the = operator or in the inspector. Unity 101

[summer stump]

= sign
Or in the inspector

[winter tinsel]

what

[wintry quarry]

x = y; assigns the value of y into x

that's the assignment operator

or, you assign in the inspector

[summer stump]

shippy = [something]

Or drag and drop the object with the script via the inspector

[winter tinsel]

cant cause its a prefab

[wintry quarry]

Then you must assign it at runtime.

[summer stump]

This is a good resource for references
https://unity.huh.how/references

[winter tinsel]

can i tag a script?

[summer stump]

No

[wintry quarry]

I don't know what tagging a script means or how that's relevant

[winter tinsel]

how do i assign at runtime

[wintry quarry]

See here

[winter tinsel]

allright

thanks

[rough orbit]

I know I've missed something fundamental here, but the error message "'Collision2D' does not contain a definition for 'tag' and no accessible extension method 'tag' accepting a first argument of type 'Collision2D' could be found (are you missing a using directive or an assembly reference?)" tells me nothing.

It works fine for OnTriggerEnter2D. What am I not getting?

[wintry quarry]

Collision2D does NOT contain a definition for tag

[raw token]

Collision2D does not have a tag member. But it does have references to the incoming Game Object, and either collider

[rocky canyon]

collision.gameObject

[wintry quarry]

Note that the parameter for OnTriggerEnter2D is a Collider2D, which does has a tag property. Collision2D is a different beast

[cosmic quail]

collision.gameObject.CompareTag("Obstacle")

its not recommended to use == for tags

[rocky canyon]

why u have Trigger and Collision?

[cosmic quail]

why does ur code make it look like OnTriggerEnter is inside Start 😄

[rough orbit]

Oh ok! So changing to Collider2D gets rid of the error message, but my player isn't slowing down when hitting an object tagged Obstacle.

[rocky canyon]

weird braces

[wintry quarry]

You can't just change it to Collider2D

OnCollisionEnter2D only accepts a Collision2D parameter

[rough orbit]

One object is a trigger to speed up the player, other stuff are obstacles I'm not supposed to be able to pass through

[wintry quarry]

If you don't use Collision2D as the parameter it's not going to get run by Unity at all

[rough orbit]

Because Im learning this as Im going and I essentially have no idea what im doing

[burnt vapor]

That's not the issue, and the method doesn't accept this type of class in general. The answer was already given

Consider looking up the documentation of these collission methods

[rocky canyon]

ahh i see so ur detecting when it enters another trigger elsewhere.. but the script itself has a solid collider on it?

[rocky canyon]

it always good to experiment a little before u try to implement it into ur game..
like an empty scene.. just testing the colliders and triggers and how they work etc

[hallow acorn]

does somebody know what quaterion.w is?

[rocky canyon]

its the magic 4th dimension

[hallow acorn]

ok so what should i do if it says i have to put a 4th float??

[rocky canyon]

why u need to know? theres methods to convert Euler angles to Quaternions so u dont have to deal w/ that stuff

[polar acorn]

The fourth dimension of the 4D vector that makes up an orientation

[polar acorn]

99% certain you are not doing what you think you're doing by making a quaternion

[rocky canyon]

use Euler angles instead

[hallow acorn]

Instantiate(projectilePrefab, transform.position, new Quaternion(transform.rotation.x, Random.Range(FirePoint.transform.rotation.y - 3, FirePoint.transform.rotation.y +3), FirePoint.transform.rotation.z));

what should i do instead?

[polar acorn]

Yeah that's not how quaternions work

[rocky canyon]

https://docs.unity3d.com/ScriptReference/Quaternion.Euler.html @hallow acorn

[hallow acorn]

(and is there a way to make this shorter i just want to set the y rotation)

[polar acorn]

Get the object's euler angles, modify the y value of that, then use the method spawn just linked

[rocky canyon]

don't mess w/ quaternions directly..

unless ur a math major

[hallow acorn]

yeah im definitly not haha

but siriously wtf does the 4th dimension mean in that context???

[rocky canyon]

dont worry about it

[rough orbit]

Seems like I got it working, thanks. Collider2D accepts just the tag while Collision2D requires gameObject.tag

Gonna have to read up on why

[rocky canyon]

https://quaternions.online/ you can play with it here to help visualize what it does.. but it wont help

[hallow acorn]

but i wanna knoww xD

[hallow acorn]

my brain is exploding what in the world

[polar acorn]

Quaternions are not values in euclidian space. They're a mathematical operation that when applied to a 3D object produce a transformation of that object in 3D space

[rocky canyon]

riiiite

lmao

[polar acorn]

They're not related to the three spatial dimensions

They're not "X axis, Y axis, Z axis, and some fourth thing" none of the values have anything to do with any of the axes of 3D space

[hallow acorn]

bro is speaking like he invented math how can one understand this whatt

[polar acorn]

The 3D space comes from the interaction between those values

[polar acorn]

That's the neat part - you don't

Never make quaternions by hand

[rocky canyon]

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

like i said, its best to ignore them.. and just know they're magic

[hallow acorn]

bro i dont even understand normal wikipedia articles xD

[rocky canyon]

use helper functions to convert Eulers.. (what we're familiar with) to quaternions

[hallow acorn]

k ill remember

ok how does the index of the set eulerAngle work im stupid i guess

[rocky canyon]

index?

[hallow acorn]

i meant syntax im stupd af

[rocky canyon]

        // A rotation 30 degrees around the y-axis
        Vector3 rotationVector = new Vector3(0, 30, 0);
        Quaternion rotation = Quaternion.Euler(rotationVector);```

Quaternion.Euler (regular vector 3)

[hallow acorn]

tysm you carried my project bro xD. without you i would have done just a third of my game jam progress haha

[rocky canyon]

no worries 👍 just here to help when i can

[winter tinsel]

ok one last thing before the very prealphademowhateveryouwannacall it of my starter game is finished

how do i make a radius in which enemies spawn randomly?

random.insideunitcircle works but it spawns things inside the playarea

when i need them to spawn outside

can i just make the playarea somehow a place where they cant spawn? like form 9 to -9 and 5 to -5 and everywhere in between you cant spawn it so pick a different place

[broken cargo]

You can just randomize X, Y and Z components independently. But it will be a rectangle/box not a circle/sphere

[winter tinsel]

doesnt really matter what shape it is

just that the enemies spawn outside of a determined area

[broken cargo]

You will still need some min and max bounds

[winter tinsel]

how do i set those

Vector2 minbound = ??
Vector2 maxbound = ??

and then how do i make it spawn between those bounds

[broken cargo]

You can use Random.insideUnitCircle for direction and than randomize a float between min and max to get a point that is atleast min from the center

[winter tinsel]

direction??

[broken cargo]

vectors can be defined as direction * distance, so Random.insideUnitCircle.normalized can be your direction

[winter tinsel]

what does the normalized do ?

[rocky canyon]

makes it a 0 or 1 value

[broken cargo]

makes vector's magnitude == 1

[polar acorn]

Well, makes it exactly 0 or 1

[rocky canyon]

yea ^

[polar acorn]

not 0-1

[rocky canyon]

lol.. bad punctuation

u normalize ur direction.. and then multiply it by ur distance..

ensures consistency

[winter tinsel]

it can be -1 too right?

[broken cargo]

vector components will be -1 to 1, but the magnitude will be 1

[rocky canyon]

even unity docs has weird punctuation

1.0. eh? lol

[short hazel]

1 [decimal point] 0

[broken cargo]

It is not (1,0) but 1.0f

[winter tinsel]

ok so can i do something along the lines of

[rocky canyon]

ahh makes sense

[winter tinsel]

wait then how does it amount to a vector?

if its a float?

[short hazel]

It's the length of the vector

[winter tinsel]

on what axis

x or y

or whichever one we want?

[rocky canyon]

1 and 1.0f are practically the same distance.. they said f to clarify it was 1.0

[polar acorn]

Well, technically -1 is just 1 but in the other direction

[summer stump]

It is the magnitude (combined x and y)

[polar acorn]

It makes the magnitude of the vector 1, unless that magnitude is 0

in which case it remains 0

[broken cargo]

It is length 1 along vectors direction. This is why it defines this direction

[short hazel]

All of them. Magnitude is computed using square roots and the squares of each individual XYZ values

When you normalize a vector, it will scale the XYZ so the resulting magnitude is 1

[broken cargo]

Vector2.one.normilized points north-east but it's magnitude is 1.0f instead of 1.41f

[rocky canyon]

when u get the random points he's saying make it a direction..

normalizing just keeps em all ranged at 1

u still get a direction.. but it keeps it uniform when u go to multiply it by distance

so (1) direction * 10 is the same distance from u as (2) direction * 10

[short hazel]

Forgetting to normalize is a very common cause of the "why am I faster when going diagonally?" problem

[rocky canyon]

first problem i ever solved 🙂

[hallow acorn]

what exactly is the difference between referencing a component by hand using public and using getcomponent?

[polar acorn]

If you can reference a component in the inspector, you should

GetComponent is used for the times you can't

[hallow acorn]

oh im using it by myself ig

but i just followed the tutorial

[hallow acorn]

like if you want to acces a specific clone or sth?

[polar acorn]

If you are trying to reference a component from an object you get at runtime through various means

such as if it's spawned in, or you want a component from something like a raycast or OnCollision

[hallow acorn]

ok ty

[late burrow]

so primitives cant be null but entries inside array can

[willow scroll]

No, if the entry is primitive

[languid spire]

if it is an array of primitives, no. But the array itself can be null

[late burrow]

i legit have string array where some entries are null

[willow scroll]

Because string is not primitive

It's a class and a reference type

[languid spire]

string is not a primitive

[willow scroll]

public sealed class String { }

public readonly struct Int32 { }

public readonly struct Boolean { }

[summer stump]

Keep in mind, the true difference is between a value type and reference type. Value types cannot be null. Reference types can. String is a reference.

(Just mentioning this because this holds for things like Vector3 as well, which cannot be null)

[late burrow]

but if a string is reference would it mean copying its contents to another variable makes them both shared?

[slender nymph]

yes, but strings are also immutable so every time you modify a string it creates a new string object

considering how you are trying to make c# a stringly typed language, you should really consider learning how strings actually work

[rich adder]

Vector3? pos = null;

[polar acorn]

stringly typed

[slender nymph]

fun fact but it's not actually null. it's just weird and allows null to be assigned, but assigning null basically just sets its HasValue property to false

[rich adder]

ahh nicee TIL
makes sense , it already seems like some hacky way to make nullable values. Still amazing, I don't use them often though myself

 public struct Nullable<T> where T : struct
 {
     public Nullable(T value);

     public bool HasValue { get; }
     public T Value { get; }

     public override bool Equals(object other);
     public override int GetHashCode();
     public T GetValueOrDefault();
     public T GetValueOrDefault(T defaultValue);
     public override string ToString();

     public static implicit operator T?(T value);
     public static explicit operator T(T? value);
 }``` oh shiee

and also value gets null as yea

[eternal needle]

I dont think it's that popular of a design to begin with

[rich adder]

yeah feels a bit awkward

[summer stump]

Every time I begin implementing nullables, I end up tearing then out

[rich adder]

I wonder what the though was there for adding it. I've only had it a few bools before, forgot why I even had it though lol

[broken cargo]

Sometimes it's useful to just have an extra possible state for a variable. I use it often with Vectors

[languid spire]

say you have an int which may or may not contain a valid value and one of the valid values is zero. An int? solves the problem nicely

[eternal needle]

It's definitely a niche case to need one though, at least in unity imo

[languid spire]

not so sure, imagine Vector3? target. Allows you to know if a target exists without the usage of an extra bool

[rich adder]

funny enough I had this exact usecase last night

[queen adder]

I need some help Im trying to give this gameobject a TMP and it just wont format properly

[broken cargo]

Looks like you have a UI component outside of your Canvas

[rich adder]

#📲┃ui-ux

[short hazel]

Also UI elements are not anchored, they won't move if you change the resolution

[queen adder]

I moved the canvas into the base it seems to be working thank you and @rich adder navarone i wont do it again I had no idea lol

[rich adder]

no worries. glad its sorted

[queen adder]

yep thank you and another question ive got a SO and im wondering how I can turn a float into the SO's value

[rich adder]

wdym a float cannot be an SO. what are you trying to do exactly ?

[queen adder]

I got a float "currentHealth" I want it to equal the SO value

[rich adder]

whats inside the SO

SO is a class

classes contain floats or whatever type , how would assigning float to a class make sense

[queen adder]

Im now confused

The SO is being accessed from another script

[rich adder]

okay but why do you want to assign currenthealth to SO?

[queen adder]

Because I got a health bar I want the heathbar to equal the SO value so I want current health(Current heath is what makes the heathbar value) to equal the SO

[tawdry rock]

Can someone help me with scriptable objects? I made a base scriptable object class name ItemSO, then i made another one called FoodSO. this inherits from ItemSO then i made a Monobehaviour script called Items that holds a refference for ItemSO public ItemSO item; and i dragged the file to the refference slot thats is made with FoodSO. Now this Items class sit in a gameObject and i have a button has a method that requires a gameObject. UseBTN(GameObject itemToConsume); I get and pass the gameobject refference via mouse hoover and now if i try to set a UI element with descriptionText.SetText($"You restored {itemToConsume.GetComponent<Items>().item.hunger} amount of hunger."); this gets me a error and says ItemSO doesnt contain "hunger" (because FoodSO contains it.) Why can't i access it?

[rich adder]

you ideally don't want to change data on the SO. You probably want to copy the value from SO put it in a float then just change the float you copied. Healthbar should be linked to that float no SO

two SO questions back to back

[languid spire]

itemToConsume.GetComponent<Items>().((FoodSO)item).hunger

[eternal needle]

I mean I can definitely think of use cases myself, but I feel you have to design around using nullables at least if its commonly used. Dont wanna go too far into this hypothetical but at the same point, you're assigning null to this target Vector3 to use it as a nullable based on some condition already

[queen adder]

Wait so i shouldnt change the actual value of the SO? So how would I be able to get the value to save across scenes?

[rich adder]

use DDOL https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[queen adder]

holy moly that should fix everything

[rich adder]

can also make it a singleton(not the player)
for easy referencing across scenes
https://unity.huh.how/references/singletons

[young fossil]

Hello. I have a question: is it a fair assessment to say the games dev community have much less error handling than in other software dev?

[queen adder]

I dont know what that is will that explain it also why arent yo usuposed to change the values on SOs?

[languid spire]

absolutely, try none at all

[young fossil]

What do you mean? Sorry

You mean most community have no error handling at all

[rich adder]

I mean you can depending on usecase but imo better you learn the traditional way of things first .
if you have multiple objects with the same SO you change one it affects everyone else with that SO

[languid spire]

generally Game devs don't do any error handling, they expect everything to 'just work'

[queen adder]

Im using to store the value of coins and another scene is a shop to spend the coins is that good or bad

[young fossil]

Aha okay. So I guess to be a good games developer, or any form of C# programmer, I should start introducing software dev level error handling in my code?

[rich adder]

imo bad

[tawdry rock]

Can you explain this a bit? I tried itemToConsume.GetComponent<Items>().GetComponent<FoodSO>().hunger; bit it was not good. Your code gives me some error too.

[rich adder]

do you want the values to reset on each run ?

[languid spire]

not quite, you have to be selective. Use it when it is required and only then. App devs tend to expect everything to go wrong and code accordingly

[queen adder]

No i dont they need to stay the same

[rich adder]

if player crashes or leaves game they lose all their coins

[young fossil]

But shouldn't I incorporate the mentality anything can go wrong?

[queen adder]

That is not good

How should I be storing the values?

[languid spire]

no, because full error handling can and will impact FPS

[young fossil]

Since you are experienced in the industry, if you were looking through code with no error handling vs code filled with error handling, which coder would you prefer to work with off the bat?

Even simple null checks

and error logs for unexpected behaviour

[rich adder]

start simple use Playerprefs, later on use files.

[languid spire]

neither

[queen adder]

Okay I should be using playerprefs for these types of things

[languid spire]

perhaps you might like to tell me what error

[young fossil]

Does the performance loss come from the real-time nature of games dev, where as the event driven behaviour of app dev is more suitable for full error handling

[rich adder]

in the beginning is ok. Ideall you want to store a local file
maybe a slight encryption algo so its not easy to read/modify value by everyone
(this is never as safe as saving on server)

[young fossil]

Or is it a practise that has been pushed on to people without much use

[languid spire]

exactly, only in very special circumstances in app dev is millisecond performance important, in game dev it is vital

[queen adder]

That makes sense this is my first actual project im not worried about it this project is just to get my feet wet in programing and making and finishing a game

[polar acorn]

What is item

[languid spire]

I copied item from your code

[young fossil]

Does this apply for all code or just code inside Update.

For example, let's say I am making a survival game. Would it be acceptable to use app dev level error handling for the inventory UI/management, since it most likely is event driven.

Where as the movement, animations, etc of the character would be super light on error handling?

[rich adder]

yes not a problem. Its easy if you keep practicing and you have the mind for it/learning

[tawdry rock]

item is the name given to hold refference for the scriptable object public ItemSO item; and FoodSO inherit from ItemSO

[eternal needle]

In game dev at least, there also isnt that much to even error check. Your real errors isnt gonna come from cases you can think of in the first case, and at some point you have to trust what you're given. Example, you have to trust the vector passed from the new input system isnt infinity in magnitude

[polar acorn]

In the same script that's throwing the error?

[languid spire]

it should really apply to everything, bear in mind Unity is single threaded so any time taken to update the UI will impact your deltaTime

[queen adder]

Okay good alright PlayerPrefs to store things like coins and programming that is?

[rich adder]

store some basic data like coins yes

[young fossil]

Also why do I never see
throw new InvalidOperationException
and error handling syntax like this often in Unity dev?

[queen adder]

Coins okay would player stats like health and damage be used PlayerPrefs

[rich adder]

anything you plan on saving between scenes/runs

[languid spire]

because Exception handling is extremely expensive

[tawdry rock]

No, its a MonoBehaviour class called Items. Like i have scripts ItemSO for the base, FoodSO that inherit from ItemSO and Items that goes on gameobjects. Im trying to get into FoodSO from a 4th scripts via buttons.

[rich adder]

could help you out 😉 https://youtu.be/qKXnkgynYG0

[polar acorn]

Chances are you'd not ever actually be able to enter a state where this would throw. When you're making an API, errors like that are good for letting the users know they're interacting with it incorrectly. In a game, the players are not developers. Exposing an error like that is not helpful, instead you should just handle it

[young fossil]

Do you have any resources/example projects/anything to give me a good idea of error handling for Unity?

[queen adder]

Yep thats it and okay lol ill take a look

[polar acorn]

So, in the script that is throwing the error that item is undefined, what is item

[languid spire]

sorry not really. tbf it's not a problem to use app dev level error handling when your are doing the development and just remove it for a production build

[tawdry rock]

item is a refference that sits inside Items class. SteveSmith wrote to try this itemToConsume.GetComponent<Items>().((FoodSO)item).hunger and it doesnt recognized what is "item".

[young fossil]

Ah this could be implemented with complier code. IF UNITY_DEBUG etc

[languid spire]

indeed, in app dev we always say make sure to fail gracefully and under control. In game dev we say, let it crash, game testing will sort it out

[polar acorn]

Did you ever post !code to actually show what the context is

[eternal falcon]

Posting code

Good overview. When you say Game Testing, that means QA, playtesting, etc?

[languid spire]

yep, which is why we spend hours and hours play testing, it's not just to get the game balance right but also to iron out the bugs

[queen adder]

Are the unity docs the place to learn everything (like playerprefs)

[young fossil]

So for solo devs, who don't have the luxury of full QA teams and dedicated play testing groups, it is viable to go the app level route, but use complier code and a combination of self playtesting?

[languid spire]

yep, although if you live near a Uni that does game dev they love to have projects for play testing by the students

[languid spire]

you wrote
{itemToConsume.GetComponent<Items>().item.hunger}
if item does not exist in my code it didn't exist in your's either

[slender nymph]

i'm pretty sure the issue is because your cast and parentheses are fucked up. shouldn't it be (FoodSO)(itemToConsume.GetComponent<Items>().item).hunger

or maybe one extra set of parentheses

[languid spire]

distinctly possible, the problem of writing code without an IDE

[tawdry rock]

ItemSO: https://paste.ofcode.org/3imFdmqmaVzjWDxywiTGsJ
FoodSO: https://paste.ofcode.org/39zLVA4uM6F4SWVPSxK7GAD
Items: https://paste.ofcode.org/8CeSNW9ZCTSxMfchPeLTS4
ContextMenu: https://paste.ofcode.org/336emkfzVWuPs7SX43BQXhs

In the ContextMenu class where i try to access the FoodSO's hunger float value.

[languid spire]

the point is, casing item to FoodSO so the hunger property can be accessed

[slender nymph]

lol what ever happened to "I compile every line of code i write into IL in my head"

[languid spire]

but not when I'm typing into discord

[polar acorn]

Okay and what lines are showing the errors

[tawdry rock]

Context menu around line 53 where i commented everything out.

[polar acorn]

Okay, so, presumably, that isEdible is only true in FoodSO instances, right? That's how you're determining it's food?

[tawdry rock]

Yes, i know it's dumb because i could determine with the enums category but for the shake of practice i made it.

[queen adder]

Would playerpreffs go in start or update or their own thing

[polar acorn]

So, get rid of isEdible and replace this condition:

if (itemToConsume.GetComponent<Items>().item.isEdible)

with this one:

if (itemToConsume.GetComponent<Items>().item is FoodSO foodItem)

(also you should consider making itemToConsume of type Items to avoid the get component)

Then you can use the variable foodItem inside the if condition directly

[summer stump]

It depends on what you mean. Calls to it go in different places

Loading, then sure awake or start is good

[twin harness]

im facing a weird issue with the input system.

using UnityEngine.InputSystem.EnhancedTouch;
using Touch = UnityEngine.InputSystem.EnhancedTouch.Touch;

...

    private void Awake()
    {
        EnhancedTouchSupport.Enable();
    }
    void Update()
    {
        if (Touch.activeFingers.Count == 1)
        {
            Touch touch = Touch.activeFingers[0].currentTouch;
            Debug.Log("Touch phase: " + touch.phase);
        }
     }

But when I press once and hold, it keeps showing the phase Began again and again.

Any idea what might be the issue here?

[viral hatch]

Idk where to put this so this is probably wrong but

Im trying to make a VR Hand setup, but "XR Controller (Action-Based)" Is not appearing, How can I fix this or make a working hand?

[queen adder]

Im brand new to PlayerPrefs im just setting one up but to change it will it need to go into its own method

[summer stump]

#🥽┃virtual-reality

[olive galleon]

should i subscribe to events in awake or start

[summer stump]

Not enough information

Is the event in the same class? Or a different one?

[polar acorn]

General rule of thumb: Do stuff related to yourself in Awake, do stuff related to other objects in Start

[tawdry rock]

Thank you so much for your time (and yours too SteveSmith), it works now. I made isEdible bool as a precondition. For example if you have a "can of something" it considered as food but you need to open it to make it edible. You and a few others been a great help for very long time.

[summer stump]

Random.Range gives a float value. Plug those values into a Vector

[queen adder]

Vector2 name = new Vector2(Random.Range(number, number), Random.Range(number, number));

np

I got a question what the heck is wrong

{
public TMP_Text coinText;
public int Coins = 0;
// Start is called before the first frame update
void Start()
{

}


// Update is called once per frame
void Update()
{
    coinText.text = PlayerPrefs.GetInt("Coins", Coins);
}
public void SaveData()
{
    PlayerPrefs.SetInt("Coins", Coins);
    PlayerPrefs.GetInt("Coins", Coins);




}

}

This is what is not working void Update()
{
coinText.text = PlayerPrefs.GetInt("Coins", Coins);
}

says I cant turn int into string

[rich mountain]

turn the int into a string

[queen adder]

Will that change anything or will it still work the same as an int

[summer stump]

Coins.ToString()

Also load the data once. Not in update

[wanton pecan]

Guys what mobile apps do y'all suggest for Beginners

[queen adder]

Will it make it change at all times

[wanton pecan]

Or short vids

Teaching

That r actually fun

Not boring

[polar acorn]

...mobile apps?

for what

[summer stump]

You should not be changing it via playerprefs.
You just change the variable directly

void AddCoins(int amount) {
  Coins += amount;
  coinText.text = Coins;
}

There is no reason at all to do any of that in update

[warm raptor]

hello here is the part of the script of my serveur that send the infos of all the player of the game to each player of the game, but when someone disconect this part of the the script tell me that message can't be send to the player that has disconected. How can I make to remove the player from the dictionnary if the serveur can't send message to this player ?

public void SendToGamePlayers(string gameId, string message)
{
    if (GameDict.TryGetValue(gameId, out var game))
    {
        foreach (var playerId in game.Players.Keys)
        {
            Sessions.SendTo(message, playerId);
        }
    }
    else
    {
        Console.WriteLine($"Game with ID {gameId} not found.");
    }
}

[queen adder]

Okay thank you

[bold plover]

Man. Bit the bullet with learning a state machine I felt was jank but decent to start with but now I think I'd have to use a lot of double code to implement it in a manner appropriate for my purposes. Sheesh.

Lessons learned.

Like I'd have to pass the proper stats from one state to the current state script and the current state script back to what I'm using to control movement. damn

lmao

Feels like in the end that defeats the point of the state machine.

[wanton pecan]

Learning code

[raw token]

If it's actually throwing an exception, you can use try/catch blocks to capture the exception. Remove the player from the dictionary in the case of that specific exception, and throw it again otherwise so as to not suppress other, unrelated errors

[hallow acorn]

why does it say that? "UnityException: Invoke repeat rate has to be larger than 0.00001F)"
InvokeRepeating("LaunchPrefab",1 , Random.Range(spawnRate - 2, spawnRate + 2));

[cosmic dagger]

Because the value can be 0 (or close to 0) . . .

[hallow acorn]

but my spawnrate is 5

[warm raptor]

I already tried to do that, but It seam that it didn't work

public void SendToGamePlayers(string gameId, string message)
{
    if (GameDict.TryGetValue(gameId, out var game))
    {
        foreach (var playerId in game.Players.Keys)
        {
            try
            {
                Sessions.SendTo(message, playerId);
            }
            catch (Exception ex)
            {
                game.Players.Remove(playerId);
            }
        }
    }
    else
    {
        Console.WriteLine($"Game with ID {gameId} not found.");
    }
}

[eternal needle]

Add a debug, because you are assuming what it is while an error is clear in telling you what's happening.

[hallow acorn]

wdym how and where should i add a debug?

[polar acorn]

Why would a mobile app have anything to do with that?

[cosmic dagger]

Cache the result in a variable and log the variable before you use it . . .

[eternal needle]

If you arent aware of what a debug.log is, you should stop and learn it immediately . Look at the docs on how to use it. Print out what the number is

[hallow acorn]

ik what a debug log is i just didnt knwe where to put it bc im stupid lol

[cosmic dagger]

It's easier to read a website, watch video tutorial, or even do a course. Most coding apps teach the bare basics (minimum) of a language and leave the rest behind pay walls. There's no telling how in-depth they go into the language as well . . .

[raw token]

It may not be actually throwing an exception then. You may need to consult the #archived-networking channel, or the community for whatever networking library you're using. You might also check the documentation for that SendTo() method (or whatever it depends upon, if you wrote the method) to see if it returns anything useful

[eternal needle]

Well think logically, a value is causing an error. You would want to see the value before the line of the error, so as another said, cache it then print it out

[warm raptor]

ok thx (one of the major problem is that the library I use does'nt have a lot of documentation 😭 )

[hallow acorn]

but it still says five

[eternal needle]

Show the debug line and the console

[queen adder]

Hi everyone. I'm not understanding coroutines. If I put a coroutine in the Update, it just repeats infinitely without waiting. How can I make this code work? This coroutine gets executed only once.

[ivory bobcat]

Explain what you're trying to do

[eternal needle]

look at what you're doing logically, at when you are waiting. What code is supposed to happen after waiting

[queen adder]

Execute the coroutine infinitely and making the 5 seconds timer work at the same time. In the Update, the timer seems to be ignored.

[hallow acorn]

i changed it a bit to do the random range too why is it out of my range? Debug.Log("number " + spawnRate); Debug.Log("number random " + Random.Range(spawnRate - 2, spawnRate + 2));

[polar acorn]

You've got nothing after the wait. The coroutine waits 5 seconds, does nothing, then ends

[ivory bobcat]

Coroutine
    while true
        add force
        play 
        yield```

[polar acorn]

You might want to either put it in a loop, or call StartCoroutine after the wait

[eternal needle]

Looks like you have 2 instances of this object

[queen adder]

So, can a for cycle in the Update work?

[queen adder]

Oh thanks

[hallow acorn]

wdym?

[eternal needle]

What part isnt clear? I meant exactly what I said

[polar acorn]

Disable collapse

[queen adder]

So coroutines are just normal functions (?). Why do we call the "coroutines" if I can make my own function and repeat getting the same result? Does a coroutine has something more?

[eternal needle]

Actually, turn off collapse in your console and itll be more clear

[polar acorn]

So we can see them all in order

[eternal needle]

Damn digi too fast

[polar acorn]

A coroutine can wait

[queen adder]

So the only purpose of using a coroutine is because I want to use the WaitForSeconds?

[hallow acorn]

damn why is it sometimes zero this makes so not sense

[polar acorn]

Yes

[queen adder]

Ok thanks.

void Start()
{
LoadData();
instance = this;
coinText.text = "Coins: " + Coins.ToString();
Coins = PlayerPrefs.GetInt("amountCoins");
}

// Update is called once per frame

{
    if(Input.GetKeyUp(KeyCode.Escape)) 
    {
        AddCoins(1);
    }

    public void AddCoins(int amount)
{
    Coins += amount;
    coinText.text = "Coins: " + Coins.ToString();
}

}

I am confused this should be setting the playerPref to coins on start but when I play add coins then stop game then reboot it it resets the coins anybody know what ive done wrong?

[polar acorn]

you were supposed to read the bot not just call it again and repost the same unformatted code

[queen adder]

lol yea I figured that one out

[hallow acorn]

oh yeah bc i have 3 canons but why isnt it 5 on all objects?

[summer stump]

Why do you do PlayerPrefs.GetInt twice?

[polar acorn]

Every instance of this script is going to have its own spawnRate, and thus roll different values based on it

[queen adder]

To make coins = the playerprefs is that wrong?

[hallow acorn]

omfg im so stupid i should propably set it to 5 on every canon

thanks a lot you helped me out once again

[summer stump]

Well yeah, you do that in LoadData

Right now LoadData reads the file and throws away the value

[queen adder]

That did not make it save

public void LoadData()
{
PlayerPrefs.GetInt("amountCoins");
Coins = PlayerPrefs.GetInt("amountCoins");
}

I think I need to save it somewhere

Im very confused

Why would you be calling GetInt twice? Remove the first one

And that is loading, not saving, so I am not sure what you mean.

Ah, you mean to the variable

If there is an amountCoins in playerPrefs, that is how you would do it

[queen adder]

this is what i got now https://gdl.space/eticemuwaq.cpp

[sharp abyss]

I am trying to walk my character manually but I did it by adding force when getting key up(when I stop holding button , it gets leg to normal rotation).I dont think thats the proper way to do that.If you couldnt understand, games "daddy long legs" and "steppy pants" are some examples.

[queen adder]

Im not sure whats wrong I click esc to save it dbug says I am then i do it again but it isnt

[summer stump]

That is not the whole class

[queen adder]

https://gdl.space/jewerebita.cpp that should be

[wintry quarry]

QWOP was the original!!!
https://www.foddy.net/Athletics.html

[sharp abyss]

ohh I forgot about that it has been so long since it came out

[wintry quarry]

I would say - more like setting joint properties than adding forces manually.

[sharp abyss]

but mine is simpler only the yhighs

[summer stump]

https://gdl.space/kuwogiluyi.cpp
Look how I changed it (LoadData)

[queen adder]

Ok

[queen adder]

Wait but how is it getting it now?

ill run it and see

That did not work

[summer stump]

Look at the line right after. If you do not have an = sign before GetInt, it does NOTHING

[summer stump]

You are saving to amoutCoins, but loading from amountCoins

[queen adder]

Is that wrong? I figured it would use the same thing

[summer stump]

Those two are NOT the same thing

Look closely at the spelling

You made a spelling error

[queen adder]

holy moly...

It fixed well thats 30 mineuts wasted

hey at least I understand playerprefs now sweet

[tall nest]

Hello everyone, how's all going? I hope you're good
Please help me fixing these errors, I got 26 error

[short hazel]

Consider using a constant to avoid repeating (and misspelling) strings:

// In the class
private const string CoinsAmountKey = "amountCoins";

// In methods
PlayerPrefs.SetInt(CoinsAmountKey, Coins);
Coins = PlayerPrefs.GetInt(CoinsAmountKey);

[polar acorn]

Llooks like there's issues in your URP package, maybe you need to update it?

[tall nest]

is it because my disk is full?

[polar acorn]

Possible, if it was full when you tried to install it

things couldd be missing

[tall nest]

because when I launch the project it keep saying not enough space

[fickle plume]

@tall nest Remove hate speech from your pronouns or you will be removed from the server.

[queen adder]

I will def do that thanks

[tall nest]

My main disk keep refilling

why?

I can't free anything anymore

[polar acorn]

Have you cleared any space?

[tall nest]

I cleaned like 13gb and it got refilled again

I always delete and it fills again

[polar acorn]

If it's the same things coming back, then you should probably find whatevers generating them and fix that

[tall nest]

not the same things

it's some windows stuff

[polar acorn]

So then there's probably other things that are trying to go into your drive but can't because it's too full which means you're gonna probably need to aggressively clean up some space

[tall nest]

Can I just move my user into the other disk so the packages get installed in the temp folder or smth?

[polar acorn]

Moving files to another place on the hard drive does not make the hard drive less full

[tall nest]

I mean the other hard disk, my user is currently in the C:\ I thought I can move it to E:\

[lusty plover]

I am trying to use the Unity AI But i got these errors after installing the library. Any help?

[polar acorn]

I can't answer that without knowing everything installed on your machine and how you're configured. If there's literally nothing you can think of that can be deleted or moved your hard drive is probably just not big enough

[fickle plume]

This is a code channel. And check space, antivirus blocking packages etc. and post full information in #💻┃unity-talk

[tall nest]

Can I just install packages in another place?

[polar acorn]

they're in your project folder

[tall nest]

Then why does it say not enough space, I have placed my project in the disk that has around 70GB free

[fickle plume]

@tall nest Also has no relation to the code channel.

[tall nest]

So where I should talk?

"Fogsight"?

:/

[fickle plume]

@tall nest Try reading the channel

[calm forge]

done this

[polar acorn]

And is your error underlined in red?

[calm forge]

ya i was getting it before too

lemme check

[calm forge]

oop ye

i just deleted where thier was red line i dont think i did mistake in spelling but oh well i works now

[polar acorn]

Now you can look at the green underline

[ivory bobcat]

You see that green squiggly like?

[polar acorn]

and compare that word to the tutorial's

[ivory bobcat]

Human error is common and should be considered the first to be questioned when debugging code from tutorials - which thankfully an ide that's configured might be able to assist with (green squiggly line)

[calm forge]

Yup it was a capital U lol i corrected it tysm though 😄

[queen adder]

Is there a way to make a int from another script work for the one im on?

[sharp abyss]

I dont kow if its the proper way but first you can get the script by public *yourscriptsname *yourscriptname and I think you can access it like that

then you can create an int in the script you write this and equalize it to the other int if you need

[queen adder]

thank you lots

[ivory bobcat]

Assuming you've got an instance of that script (an object in the scene that has that script component attached) you'd reference that object as the component type (drag it into a field with that script component as the type) and be able to access that specific instance's integer membercs public MyScript myScript;//field that should have been assigned from the inspector private Start() { myScript.myInteger = 5; }

[radiant frigate]

even if i have the collisions matrix somehow the collision keeps happening

does someone know if this is a recurrent thing or am i just dumb?

[silk night]

Have you set the layers on both enemy and player?

[radiant frigate]

oh i discovered why, saw someone having the same problem, we basically used the wrong physics

yes

i was using physics when i should be using physics2D

my bad srry

ty tho!

[open vine]

Hey does anyone know how I would make an object change to the next color when I interact? I have an array of materials and a reference to the objects mesh renderer. I want to change it to the next material in the array everytime I interact. I know I have to meshRenderer.material = materials[0] to set it, but how do I make it iterate to the next one each time?

[sand heath]

if all of the materials look the same you could use a shader

if you want to change the material to a different one, just increment the index

materials[0], materials[1], materials[2] etc

[open vine]

Would I do this in a forloop? or should i write it manually

[sand heath]

can you send your !code

i need to know what you're doing before i can say what you should do

@open vine the way you have it looks perfect to me? does it not work?

ohh i see

[open vine]

Yeah it actually skips right to the last one

[sand heath]

well yeah cuz you have the for loop going through every material when interact with it

so instead, make an integer to store the index and then increment that index everytime you interact with it

then set the material to material[index]

private int materialIndex;

public void Interact()
{
  materialIndex++;
  screenRenderer.material = CCTV_Materials[materialIndex];
  if (materialIndex == CCTV_Materials.Length)
  {
    materialIndex = 0;
  }
}

oh oops forgot to increment

u get the point tho

[open vine]

Oooh thats really smart it works perfectly fine now thanks for explaining why I do this as well!

[sand heath]

and like i said if you just want to swap a color you could make a shader graph pretty easily to do that

though this way should work completely fine without touching any of that

[open vine]

gotcha, tbh I have no clue how shader graph works but if I ever need the color swapping ill look into it 👍

Are Rigidbody player controllers always messy looking? Mine works fine but I wanna organize it, but I cant really do it

[sand heath]

you might want to look at the player controller component

gives you better control (being able to code your own gravity, velocity, etc)

[queen adder]

Yes I know, I am making 3 player controllers

1. AddForce-Based Controller (Rigidbody)
2. Direct Velocity Manipulation Controller (Rigidbody)
3. CC Controller

CC is good for horror games and that sort of stuff

[sand heath]

there are pros and cons of using one, same as the other options

you sacrifice control for a physics-based solution that is easy to implement

[queen adder]

Yeah, number 2 is quite good for almost all cases though

But some physics games must have 1

[sand heath]

imo 1, 3, and 2 in order of difficulty - 1, 2, 3 for level of control

and i guess the 4th secret option of creating all your own collision and physics

[queen adder]

Difficulty of implementing? and what kind of control you mean?

[sand heath]

difficulty of implementing/writing the code for yeah, control meaning how customizable/flexible it is

(you can override/inherit from the charactercontroller to customize it further)

[queen adder]

Yeah, I would always use 2 if it wasn't for the fact that external physics forces barely affect it, since the velocity is set directly in the code

[sand heath]

you can also look at the asset 'kinematic character controller'

[queen adder]

Looks good

But im not good at player controllers whatsoever so not for me

Since you gotta write your own stuff it says

[sand heath]

it does have a pretty good walkthrough included in the files, it's pretty advanced though

it allows for a good amount of control for that cost

[queen adder]

Pretty much just better CC

[sand heath]

its more like a better rigidbody

its a lot more difficult to use than CC i think

[frosty hound]

It's a kinematic character controller, it's nothing like a rigidbody that uses physics.

It's closer to the built in CC, with more utility functionality

[digital cave]

How do I access Volume and it's settings, enable/ disable specific post processing effects in code? I can not find anything about it in unity scripting documents.

[summer stump]

Is this the URP?

[digital cave]

Yup, just found the solution (I have been trying for the last 20 minutes, and I found the it moment I asked in here)

        Volume volume = FindFirstObjectByType<Volume>();
        
        DepthOfField depthOfField;
        ColorAdjustments colorAdjustments;

        if (volume.profile.TryGet<DepthOfField>(out depthOfField) && volume.profile.TryGet<ColorAdjustments>(out colorAdjustments))
        {
            depthOfField.active = false;
            colorAdjustments.active = false;
        }

how to check if all gameobjects has the same value.
the gameojects has a script and the script has int value.
how to check if int value is same for all gameobjects.

[silver pier]

does anyone know how i can code a login? thnak you.

[eternal needle]

what part are you struggling with? have you coded anything to try doing this

[glossy turtle]

i am trying to check if the int value is same for all gameobjects so that i can show end screen;

[eternal needle]

🤔 repeating the same thing doesnt answer what i asked above. What part specifically do you not know how to do

[hallow acorn]

help me why is it doing that?? i use this line to repeat my function:
InvokeRepeating("LaunchPrefab",10 , Random.Range(spawnRate - 2, spawnRate + 2));

i think u can see in the video but spawnRate is set to 15

[eternal needle]

show the full !code

there is an array of gameobjects and i am checking if all int values are same like say 1 for all gameobjects.

[hallow acorn]

public class CanonMain : MonoBehaviour
{
    public GameObject projectilePrefab;
    public GameObject FirePoint;
    public float spawnRate;

    void Update()
    {
        InvokeRepeating("LaunchPrefab",10 , Random.Range(spawnRate - 2, spawnRate + 2));
    }

    void LaunchPrefab()
    {
        Instantiate(projectilePrefab, transform.position, FirePoint.transform.rotation);
    }
}```

[eternal needle]

add a debug in Update to see how many times you start this InvokeRepeating logic

it will become clear instantly

[hallow acorn]

oh

dont even need it

[eternal needle]

you probably want to only call this once, like in awake or start

[hallow acorn]

yeah

thanks a lot

it always takes a bit haha

You'll need to obtain references to your script components by using GetComponent<MyScript>() on each game object. From the component reference, you will be able to access whatever public members you have declared in your MonoBehaviour class.

Because GetComponent() has some overhead, it is generally a good idea to cache all of the references in another collection if this is something you will be doing often. Or just use a list or array of your MonoBehaviour type to begin with (e.g. public MyScript MyScripts[];), such that your code needn't call GetComponent() at all.

A simple means to test for equality would be to store the first value in a local variable, then loop over the subsequent items checking their value against the first.

[glossy turtle]

public class changedtop : MonoBehaviour
{

public int top;

}if (top[i].GetComponent<changedtop>().top==1)
{
countcanvas.count = changechars.Length;
}

i know but its not working.

this code is in other class.

if (top[i].GetComponent<changedtop>().top==1)
{
countcanvas.count = changechars.Length;
}

What does the loop containing this if block look like, and what indicates that it isn't working?

[glossy turtle]

thats a simple programming but i am confused here. let me say i am checking all elements in an array has same value. if they have its end or its not end.

[raw token]

Sure, I believe I understand your intention for the most part - though I'm not sure what you mean by "its end or its not end."

Is

countcanvas.count = changechars.Length;

only supposed to occur if all of them have the same value? If so, does "it's not working" mean that it's happening even when you don't want it to?

I won't code the solution for you, but if you show more of what you have done already we'll get you there. Namely, the loop. Words can be vague, but code is concise (or I guess we aspire to it being such :P).

[quartz nimbus]

Hi im just curious but what type of code would you generally use to make a player respawn after dying or getting destroyed. Essentially the player/object get destroyed to show that it has died but at the respawning phase I dont know what code to use and I have looked at forums but none have help thus far so just wondering if anyone new it here.

[eternal needle]

how do you spawn it in the first place? you should be able to just use Instantiate

[quartz nimbus]

The player is already pre-spawned in the world

the when i press player it just takes me to the camera view of the player

or am i being stupid

[glossy turtle]

its plenty of scripts dapper but finally i am checking an array if all the elements have 1 value. if they have then its like end screen. and if any one element has 0 value then its not end screen.

[eternal needle]

if you need to actually spawn the whole object again, Instantiate it then from like a prefab of the player. Though I do find it weird if you're destroying the whole object, cameras and whatever else included. Im not really sure what you mean by the lines below tbh

[raw token]

The same value, or specifically the value 1?

[quartz nimbus]

ye the whole player gets destroyed that includes that includes cam etc so i just create a prefab that instantiates it to "spawn back" essentially

[glossy turtle]

any same value.

[eternal needle]

Im not sure if destroying the whole camera is a good idea, because for a moment at least there wont be a camera in scene. Why do you need to destroy the object? You could also disable it instead and visually it'd look the same to the user

[quartz nimbus]

oh i watched a tutorial to do it and they said i to destroy the obj

so i can just disable the obj which would be much easier

[eternal needle]

many tutorials are complete shit

[quartz nimbus]

ye thats what i found out i useually rely on codemonkey or brakeys there the best they help me alot when i get stuck but none of them have done vids on charceter respawn so i got stuck

and alot dont help

ok thanks for the help so just disabling the obj is easier than destroying in reference to respawning

[eternal needle]

im not sure how your objects are parented, so just in case make sure you arent disabling the camera at least. you should be able to get away with just disabling the player model

[quartz nimbus]

there parented like this so would this be a problem

[eternal needle]

Your camera shouldnt really be a child of the player, is MechSuitTHIN the model itself? You might be able to just disable that only

[quartz nimbus]

ye the mechsuit is the model the player is just a empty obj so kust disable mechsuit ok. Thanks for the help man

[raw token]

Gotchya 👌

This is roughly the approach I was alluding to above

bool allMatch() {
  // Cache the first value for comparison to the others.
  int firstValue = gameObjects[0].GetComponent<MyScript>().someValue;

  // We already know the first value - start checking from the second.
  for (int i = 1; i < gameObjects.Length; i++) {
    // If this item's value doesn't match the first, they're not all equal - we can return here.
    if (gameObjects[i].GetComponent<MyScript>().someValue != firstValue)
      return false;
  }

  // If the loop completed successfully, all values match.
  return true;
}

But if you're doing this frequently, you really should store the component references somewhere so you're not constantly calling GetComponent()

[glossy turtle]

it worked thanks dapper.

[topaz mortar]

Why is my game not crashing when this goes over the max allowed int? It just returns 2147483641
int total = Mathf.FloorToInt(value * _multiplier + _offset);

is it because _multiplier is a float?

[north kiln]

integer operations are unchecked, so I don't know why you would expect it to crash

put it in a checked block if you want to get exceptions for it

floats also don't, and just go to infinity

[topaz mortar]

what does that mean? if I do int * int it can be higher than 2147483641? or it's just capped at 2147483641?
as long as I don't try to assign it to an int?

[north kiln]

It will loop back around

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/checked-and-unchecked

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/arithmetic-operators#arithmetic-overflow-and-division-by-zero

[topaz mortar]

"In an unchecked context, the operation result is truncated by discarding any high-order bits that don't fit in the destination type."
so it would be capped?

[north kiln]

There is no way to fit anything bigger than MaxInt into an int.

So, it follows the documented behaviour in those links

[eternal needle]

small nerd point, its not the number you wrote. its 2147483647, ends in 7

[topaz mortar]

well I just copied the value I was getting 😛 the docs do say it removes the bit, so that might cause the number to a bit different

[burnt vapor]

Pun intended?

[weak talon]

this is the material in inspector
then this is what it looks like in game

why is it so dark in game?

[slender nymph]

lighting presumably. but this is a code channel

[weak talon]

yeah idk where else to put this, but i didnt change anything to do with lighting or anything

[slender nymph]

yeah if you don't have lighting in the scene that would be why. that appears to be a lit material.
also #🔎┃find-a-channel

[weak talon]

oh, how can i make it not a lit material

[fierce geode]

Why are there two definitions of duration in the SplineContainer class

except ones deprecated and one isnt

[eager spindle]

unity things

[fierce geode]

and the only difference is that ones only a getter and the other one is a getter and setter

[eager spindle]

theres a whole layer of depercated things that can inconvenience you

[eager spindle]

the opposite of a Lit material is an Unlit material.
every material has a Shader assigned to it; the Shader decides what the object looks like. e.g. a Lit material makes it look like the objecth as lighting, and Unlit material doesnt take lighting into account.
to change a Lit material to an Unlit material, select the material. go to the Shader field below the name of the material. search for an Unlit material.

[weak talon]

yeah ok thank you

hey guys, I have a problem where UI closes itself when I click on specific point somewhere in the middle. What could cause it?

I'm out of ideas, im debugging it 2nd day now

Is it because you click the laptop again by accident?

It's not possible to be helped unless you share the relevant code for this

you should have the event system inspector open so you can see what is being clicked on

[fierce geode]

It feels a bit weird that you can access the NavMeshAgent class and reference in code; but you still have to install the package for Unity to actually use it.

[slender nymph]

NavMeshAgent is still part of the core engine, it's the NavMeshSurface and some other related components that are part of the AI Navigation package. of course that isn't really a code issue though so idk why you're bringing it up in here

[pastel idol]

about the code - I made it only possible to exit by clicking escape button

        if (isLaptopActive && Input.GetKeyDown(KeyCode.Escape))
        {
            ExitLaptopScreen();
        }

    void ExitLaptopScreen()
    {
        isLaptopActive = false;
        laptopUI.SetActive(false);
        mainCamera.gameObject.SetActive(true);
        laptopCamera.gameObject.SetActive(false);

        Cursor.lockState = CursorLockMode.Locked; // Lock the cursor
        Cursor.visible = false; // Hide the cursor
    }```

[fierce geode]

When I clicked Add Component in the editor, NavMeshAgent didnt show up until I installed the AI Navigation package. I just thought it was interesting that the editor couldn't or wouldn't detect it but the script was still available to be referenced in the code. Not really an issue, but just something I thought was interesting.

[burnt vapor]

Does it say that ExitLaptopScreen only has a single reference in the code?

Should be displayed on top of the method but this might vary per editor

[pastel idol]

thats the only reference

[languid spire]

if you debug.log in there you can see the stack trace of how it is being called

[burnt vapor]

I would assume it's somehow still called, yes

[pastel idol]

so it would be an issue with raycast or I messed up something within UI ?

[burnt vapor]

Seems unlikely it closes in a way where it also hides the cursos and all that without being a bug

Perhaps the background accidentally has an onclick listened to call the method?

[pastel idol]

nope

[pastel idol]

I added debug log there but it's not called

[languid spire]

where did you add it?

[pastel idol]

both in method and in if statement

[languid spire]

so, there must be other code also doing this

[pastel idol]

other part of code controlling cursor is this

  void ToggleLaptopScreen()
  {
      isLaptopActive = !isLaptopActive;
      laptopUI.SetActive(isLaptopActive);
      mainCamera.gameObject.SetActive(!isLaptopActive);
      laptopCamera.gameObject.SetActive(isLaptopActive);

      if (isLaptopActive)
      {
          Cursor.lockState = CursorLockMode.None; 
          Cursor.visible = true; 
      }
      else
      {
          Cursor.lockState = CursorLockMode.Locked; 
          Cursor.visible = false; 
      }
  }

and it's called after

 if (Input.GetMouseButtonDown(0))
 {
     Ray ray = mainCamera.ScreenPointToRay(Input.mousePosition);
     RaycastHit hit;

     if (Physics.Raycast(ray, out hit))
     {
         if (hit.transform == transform)
         {
             ToggleLaptopScreen();
         }
     }
 }

[languid spire]

that looks promising, put a debug in there

[languid spire]

it looks to me like this

if (Physics.Raycast(ray, out hit))
     {
         if (hit.transform == transform)

is the root of your problem
surely it should only do this if isLaptopActive == true ?

[pastel idol]

I think it's not it

void ToggleLaptopScreen()
 {
     Debug.Log("call ToggleLaptopScreen method");

     isLaptopActive = !isLaptopActive;
     laptopUI.SetActive(isLaptopActive);
     mainCamera.gameObject.SetActive(!isLaptopActive);
     laptopCamera.gameObject.SetActive(isLaptopActive);

     if (isLaptopActive)
     {
         Debug.Log("isLaptopActive true");
         Cursor.lockState = CursorLockMode.None;
         Cursor.visible = true; 
     }
     else
     {
         Debug.Log("isLaptopActive false");
         Cursor.lockState = CursorLockMode.Locked; 
         Cursor.visible = false; 
     }
 }

after UI closed it called "isLaptopActive false"

[languid spire]

yes, but should you be doing the raycast at all if isLaptopActive is true. It makes no sense to do that if the UI is displayed

[pastel idol]

you mean raycast can hit laptop when UI is open?

[languid spire]

yes

[pastel idol]

is that even possible?

[slender nymph]

why wouldn't it be

[languid spire]

of course, there are 2 kinds of raycasters, phisics for GO's and Graphics for UI

[pastel idol]

oh really

[pastel idol]

UI takes whole screen so I thought raycast can't hit whats behind it

[slender nymph]

Physics.Raycast can only detect (3d) colliders

nothing else blocks it

[quartz nimbus]

Hi so i just made this respawn script but now every time I spawn into the game It causes my cam to move towards the Respawn manager and I dont know why does anyone know how to fiix this issue

[pastel idol]

@languid spire I fixed it by adding if (Physics.Raycast(ray, out hit) && isLaptopActive == false) thank you vm you saved my game

[languid spire]

if (isLaptopActive == false && Physics.Raycast(ray, out hit))

would be better

[pastel idol]

alright, will do

[hallow acorn]

do i cause an infinite loop? my editor always gets stuck on application.enterplaymode and after 15 minutes i used my task manager and lost 2 hours progress. this time i saved before entering playmode and i still get stuck bc of this part: ``` time -= Time.deltaTime;
int totalTime = Mathf.RoundToInt(time);
while(totalTime > 0)
{
text.text = totalTime.ToString();
}

[slender nymph]

yes, that while loop is an infinite loop

[burnt vapor]

Your while loop must have a delay if it does not finish in the same frame

[slender nymph]

i'm assuming that should really just be an if statement rather than a loop

[burnt vapor]

Considering nothing in this while loop changes totalTime, it probably waits for that

[hallow acorn]

oh

yeah

makes sense

[burnt vapor]

So if this intentional, add a delay using a coroutine for example

Or make it async

[hallow acorn]

why is it so insanely hard to make a simple timer wtf

[burnt vapor]

Maybe you want to use a build in timer instead?

Depends on what you need of course

[hallow acorn]

how?

[burnt vapor]

C# supports timer classes

But I would guess you want to make a Coroutine instead

[slender nymph]

it's not, you just need an if statement rather than a while loop there (assuming this is in Update)

[hallow acorn]

i want a 5 sec countdown at the start of my game thats it lol

[burnt vapor]

Then just make a Coroutine

[hallow acorn]

ok ill try its in update yeah

[burnt vapor]

Have an integer that defaults to 5, then have a Coroutine decrement it

[hallow acorn]

i tried but it wont work idk why

[slender nymph]

you'll also want to change your condition since the display will never show 0

[hallow acorn]

the internet is complicated

[burnt vapor]

If you want it to be even better, save a timestamp that is 5 seconds in the future based on Time.time, and wait until Update passed this value

[hallow acorn]

oh so less then 1?

[slender nymph]

or just >=

[hallow acorn]

oh ok

[slender nymph]

this would also never show anything other than 0

[fierce geode]

Stupid question incoming.
I'm writing a script to hold NPC conversation Data; originally I just did one script that held the entire conversation including every route via recursion. But I'm currently testing out a new segmented approach where the script only contains one conversation and its responses; with it just pointing/referencing to the next route. Was just wondering if one approach is better than the other or its just really semantics at the end of the day.

I imagine that the segmented approach allows for stuff like looping dialogue, say if you wanted to go back to a previous conversation to repeat something much easier. But the recursive approach does make it easier to see where conversations lead; while the segmented option just points to the object where the script is located.

[eternal needle]

I wouldnt call this recursion, more like a directed graph or a tree with 4 child nodes (if you've learned the basics of graph theory). But the segmented approach imo is gonna be way better. You've already brought up the case about a looping cycle, which isnt possible in your first approach. If you need any looping dialogue then immediately you have to choose the 2nd approach.
You can easily make this 2nd approach more readable by using scriptable objects (SO). With SO you can name these assets too so it wouldnt just all be [Talk] (Dialogue Choice)

Depending on your coding abilities, you could also make your own visualization for the dialogue flow. Kinda like an animator looking tab which shows how dialogue (which would be an asset from an SO) flows from one to another

[fierce geode]

Thanks for the feedback! Yeah I'm probably going to be sticking to the segmented approach. I might look at visualization later in development. But I have used Scriptable Objects in the past, and plan to use them later in the project so I'll look into that!
