[rich adder]

then why are you checking tag on nothing

[thin sedge]

I said before I haven't been in this sort of area much 😅

[rich adder]

this method OnTriggerEnter is giving you a Collider2D of whatever was hit

[polar acorn]

So what object do you want to check the tag of

[thin sedge]

The player

[polar acorn]

And how do you intend to reference the player

[thin sedge]

With it's collider?

[polar acorn]

Where are you getting the collider from

[thin sedge]

The player Gameobject?

[polar acorn]

So you want to directly reference it? Drag in an object from the inspector?

[thin sedge]

Seems like it

So I need to serialize it?

[polar acorn]

So, if you have a direct reference to the player, what is the purpose of checking the tag

You would know it's the player then

[thin sedge]

If there's more players?

[polar acorn]

So then how do you intend to identify the player

[thin sedge]

With a tag

[polar acorn]

A tag of what

What object are you checking the tag of

[thin sedge]

The playermodel(s)?

[polar acorn]

I'm not asking what you're hoping to find. I'm asking what object you're checking

[thin sedge]

I feel so stupid in this conversation right now

[cosmic quail]

why is there a multiple page long conversation on something that can be solved by saying four words

[polar acorn]

What is the thing you're trying to check the tag of to see if it's player

[thin sedge]

The collider?

[polar acorn]

Correct. And what is the name of the variable that holds the collider

[thin sedge]

Collider2D?

[polar acorn]

No, that's a type

What is the name of the variable

[thin sedge]

OnCollisionEnter or OnTriggerEnter?

[polar acorn]

Do you know what a variable is

https://www.w3schools.com/cs/cs_variables.php

[thin sedge]

Isn't that something that holds a value? If so ignore the last message

[polar acorn]

So what is the name of the variable that holds the collider

[thin sedge]

It's either a string or a float

I think

[rich adder]

its a Collider2D why would be a string or float

[polar acorn]

What

[thin sedge]

I said that earlier!!

[rich adder]

so whats the name of it?

in the code you're looking at

[polar acorn]

At no point have you said the name of the variable

I'm not asking for the type

[thin sedge]

I thought you meant the variable itself

[polar acorn]

I do mean the variable itself

What is it called

The name of the variable

Not the type

Not what function it's in

The name

[thin sedge]

This white text?

[rich adder]

thats a variable name, but not one in the function is it

[polar acorn]

Where is this

This isn't in the code you've sent

Where are you looking

[thin sedge]

I never gave it a name 😅

[polar acorn]

Why did you make a new variable

Use the one you already have

That comes from the function

The parameter to the function is the collider you have collided with

[rich adder]

@thin sedge variables in a function( ) work exactly the same naming them outside of a function

Type name

[thin sedge]

So I need to compare the Collider2D "collision" thing?

instead of the "other" thing?

[rich adder]

🎊

[dense root]

How do I get the reference from my Ball.cs script?

[Header("Timer UI")]
public GameObject timerText;

private float TimedText;

public void TimerText()
{
    timerText.GetComponent<TextMeshProUGUI>().text = TimedText.ToString();
}

[thin sedge]

Like this:

Thank you for the help then!!

[rich adder]

is working now?

[rich adder]

you mean get reference to your ball script from here ?

[dense root]

Yeah

[thin sedge]

Yes but it doesn't reset the bool after the animation is played

[rich adder]

you need a way to reset it

code doesn't do things magically by itself lol

only when it gos awry 👿

[rich adder]

same way you made the other references before [SerializeField] private Ball ball

[thin sedge]

Thread takes up less space :)

[dense root]

Okay I've serialized the field how do I call it on my TImerText()?

[digital lynx]

i do not know why my character is not jumping. No matter what i do. I already checked my input settings. It just doesn't work. Anybody got an idea?

[rich adder]

serializefield is only for private fields btw

public fields are already serialized in inspector

[dense root]

Oh right

So how do I take that value from the inspector and dispaly it to the text field I created?

[rich adder]

you have to expose the current timer if you want to display that

not the TargetTime

since thats the starttime

[rich adder]

did u not debug what I asked earlier..

[rich adder]

ok so what is the result

[digital lynx]

it didn't show anything in my end.

i already tried everything.

[rich adder]

screenshot the whole console window in playmode

[rich adder]

well then there you go

answer shall always be revealed to you debugging

look at your jump condition again

if (Input.GetButtonDown("Jump") && isGrounded)

do you see whats wrong?

[digital lynx]

alright

[hollow dawn]

should i use visual studio code for coding c# in unity? im a beginner which one is the best to use?

[rich adder]

use whatever you want

best tool for the job is always

is catching up though, maybe in a few years

[frosty lantern]

i like the colored brackets in vscode tho

[rich adder]

VS has that too

since last year

or more

[frosty lantern]

how do i turn it on?

[rich adder]

It made my rainbow brackets useless

[rich adder]

pretty sure its defaulted on no?

VS 2022

[frosty lantern]

i don't see it

it highlights bot doesn

color on mine

[digital lynx]

i tried assigning it to spacebar, it didn't work. i really do not know.

i tried searching for any possible solutions.

[frosty lantern]

i see the setting i think but it's not doing it

[rich adder]

bro what

what part of it didn't you notice the bool

isGrounded is never tru myguy

you can't jump

[digital lynx]

sorry i really do not know.

[rich adder]

well try to understand what you're copying lol

[rich adder]

that aint it

forgot how to enable it tbh

mine was just on

see if Viasfora still works

[buoyant knot]

the debug log is telling you that isGrounded is false. Meaning you need to go find out why it is false if you actually are grounded

[desert elm]

How could I write a command that would raycast between two objects and report if it intersects with any collider other than the target object?

[queen adder]

yo Im having some issues with the new input system where i will look around for a while then suddenly it feels like i miss a frame and my character is looking way further thant it should be or just straight up looking upwards for some reason```private void Update()
{
//looking (camera rotation)
float mouseX = playerInputActions.CameraLook.MouseX.ReadValue<float>() * rotateSpeed * Time.deltaTime;
float mouseY = playerInputActions.CameraLook.MouseY.ReadValue<float>() * rotateSpeed * Time.deltaTime;

    xRotation -= mouseY;
    xRotation = Mathf.Clamp(xRotation, -90f, 90f);

    cameraHolder.transform.localRotation = Quaternion.Euler(xRotation, 0, 0);
    transform.Rotate(Vector3.up * mouseX);
}```

[buoyant knot]

Call Physics2D.Raycast, cast from point A to point B. This gives you a list/array of RaycastHit2D. Go through the list and ignore anything that is one of the two objects

[desert elm]

oh okay thanks

[wintry quarry]

Multiplying mouse input by DeltaTime is incorrect

[buoyant knot]

https://docs.unity3d.com/ScriptReference/Physics2D.RaycastAll.html

there is Raycast, RaycastAll, and RaycastAllNonAlloc

pick the one that is best for you

Raycast just gives one hit, but is simple if you can filter out the two objects by layer in a contact filter.

RaycastAll gives you a whole array to sift through.
RaycastAllNonAlloc gives you a whole list/array, but you can keep the list/array as a variable to avoid repeatedly allocating/deallocating. If you are going to call this a lot.

[buoyant knot]

I think it is a bit confusing.
+= implies he wants to parse mouse position as angular velocity, so * deltaTime is correct.
But the parsing mouse position as velocity is wacky.

i think the math here is just not correct. He would need to figure out his units

[desert elm]

thanks

shouldnt I use a layer mask though?

[buoyant knot]

you didn’t mention if the two objects have a different/same layer to what you are trying to detect, so I gave you all the options

[desert elm]

oh okay

[buoyant knot]

if A, B and C all have the same layer, then you can’t call Raycast from A to B without hitting A and B by default.

[buoyant knot]

I believe mouse position has units of pixels (it is in screen space).

RotationSpeed i assume has units of degrees per pixel (which would be wrong. rotation would change based on screen resolution).

[desert elm]

can you invert layermask?

[wintry quarry]

It's definitely incorrect here. Mouse delta should never be multiplied by DeltaTime. it's not a velocity it's being used directly to rotate a transform

[buoyant knot]

try ~. This does a bitwise inversion

this guy needs to convert from mouse space to something normalized/dimensionless. Probably needs to divide mouse pos by screen size or something first. Just get that in a 0-1 or -1-1 range

then he can multiply by his rotation speed, which would have units of degrees/second, I assume

I’d first get mouse position into a -1 to 1 scale. Then multiply it by rotationSpeed (angular velocity in degrees per second) times deltaTime. This would output a value in degrees, which is what he wants to make a quaternion based on euler angles.

his main mistake here is not converting Mouse position from screen space.

[frosty lantern]

i found it

[buoyant knot]

does that help?

[desert elm]

whats the problem here now?

[rich adder]

ah nice..of course it would be there lol

[rich adder]

read the error

most likely targets is not the same type as your script

you probably need to add the hit.whatever instead of this

what is the type for targets ?

[desert elm]

I do not want to add the thing the collider hits too the list

[unreal imp]

Guys, sorry for asking for the 99th time but I want the definitive answer on how to make an object carrying system like half life 2? (They had already told me this before but I lost the message)

[rich adder]

so what do you want to do with this script

[unreal imp]

this is the last time I will ask that

[desert elm]

I want add the current entry in the foreach loop to the list

[desert elm]

transform

[rich adder]

alright, so do you know which one is the individual transform

from the loop

[desert elm]

a.position

[eager elm]

an invisible gameobject in front of the player that is parented to the player. Any object that gets picked up will be parented to that invisible object and put to the same position.

[rich adder]

why would it be .position

you said targets is Transform

[unreal imp]

oh,thanks

[desert elm]

oh I
somehow didn't realize that- I assume just having it be a will be okay?

[unreal imp]

or empty gameobject

[rich adder]

yea

[desert elm]

thanks

[rich adder]

although name it something better than a

lol

enemy would've made more sense in this context

[amber spruce]

anyone know why that happens

[polar acorn]

Make sure that there are no compile errors and that the file name and class name match.

[amber spruce]

they all match and i dont see any compile errors

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Photon.Pun;

public class CreateAndJoinRooms : MonoBehaviourPunCallbacks
{
    public InputField createInput;
    public InputField joinInput;

    public void CreateRoom()
    {
        PhotonNetwork.CreateRoom(createInput.text);
    }
    public void JoinRoom()
    {
        PhotonNetwork.JoinRoom(joinInput.text);
    }

    public override void OnJoinedRoom()
    {
        PhotonNetwork.LoadLevel("MultiPlayer");
    }
}

thats my code

[polar acorn]

Show your console first

[polar acorn]

Clear errors first, then see what's still around

[amber spruce]

when i clear them nothing new shows up do i gotta run the game first?

[polar acorn]

What is the file name of this script

[amber spruce]

CreateAndJoinRooms

[polar acorn]

Show a screenshot of the file in your project window

[polar acorn]

Try restarting the editor

[amber spruce]

works now thanks

why cant i drag my input field into the input field thing

public InputField createInput;

i have 2 of them

[polar acorn]

Is it an input field or a TMP InputField

[amber spruce]

TMP

i always forget that

thanks

[dense root]

Any idea how come my pen isn't logging to the console?

[slender nymph]

is the component attached to an active object in the scene?

[dense root]

Oh weird I thought you needed to do that but in the tutorial he doesn't do that

It's logging an unusual name though, this is fairly common wacom

[lone sable]

I got two code related questions to some UI elements.

1: I'm running into an issue where if I mouse over a button inside of a ScrollRect, then, I can no longer use the mousewheel to scroll through the scrollrect is there a code related fix for this? Or is it a Unity Bug? It seems really strange.
2: Does anyone have anything that would support controllers inside of a ScrollRect? It seems very strange of Unity to not support Controller for this...

[north walrus]

Can something like this be simplified?

[short hazel]

public CharacterController CharacterController { get; private set; }

[steep crown]

is this comment precise enough?

i feel like it wasnt clear what it meant

[rare basin]

yikes

[rare basin]

2. just modify the scrollValue when moving the controller stick

[lone sable]

That doesn't handle selections though. Just scrolling.

[rare basin]

but wdym supporting controllers in scroll rects

[slender nymph]

dunno about point number 1, but for point number 2 if you are using the InputSystem then it's just a matter of you setting up your actions the way you want

[lone sable]

• Select an object in the scroll rect.
• Move it down
• As you move it down it will select objects out of view of the scroll rect.

[rare basin]

about no.1 scroll rect won't be detected if you have mouse over different UI element

[fierce shuttle]

1. likely it could be a default feature that you may not want to scroll when your interacting with Selectables like buttons, sliders, dropdowns, etc, you could probably toggle the "raycastTarget" value of the button so the event system ignores it, I think there may be another way but cant think of what it may be atm

[rare basin]

you won't be able to click the button if you do so

[lone sable]

Yeah, both options aren't "Normal" behaviour for a Scroll Rect in the real world.

[rare basin]

seems pretty normal to me

all scroll rects i know behave exactly like that

[fierce shuttle]

True, but if the goal is to not have scrolling stopped by hovering over the button, it coul work, when scrolling stops enable it again

[edgy prism]

Working on UI sliders that I want to stop moving when the total value is 508 or greater and Im having an absolute nightmare when I set the value to say 507 and click the far right of the slider to give it a value much higher than 508 any help is greatly appreciated

https://gdl.space/recevuhihi.cs

[lone sable]

What????

Mouse over the channels on the left and use your mouse wheel. If you're over a channel, it doesn't stop you from Scrolling. Lol

[rare basin]

just clamp it?

            if(sliderValues >= 508)
            {
                sliderValues = 508;
                return;
            }

[edgy prism]

Clamp how exactly?

[rare basin]

Mathf.Clamp the sliderValues

[edgy prism]

Sorry im not sure I follow

[rare basin]

if you don't want your sliderValues to be greater than 508

just clamp it

https://docs.unity3d.com/ScriptReference/Mathf.Clamp.html

[edgy prism]

sliderValues is just a tally of the sliders

[rare basin]

    if (sliderValues >= 508)
    {
        // If total value is 508 or greater, set all sliders to their maximum allowed values
        foreach (Slider slider in evSliders)
        {
            slider.value = Mathf.Round(slider.value / 4.0f) * 4.0f;
        }
        return;
    }

or just add this

[edgy prism]

The total value of each slider is 252 you have to achieve 508 across multiple sliders

[short hazel]

So the sum of all slider values must not exceed 508 is what you're asking?

[edgy prism]

Yes

[rare basin]

so if you have 2 sliders, one is at 500 let's say

[edgy prism]

Sorry my brain is a bit fried I think what Xaxup just said might work let me test it

[rare basin]

the second one can't exceed 8?

[edgy prism]

Exactly

[blissful trail]

having a problem where my jump function is not doing anyting despite it being called, and also my player falls super slow for some reason i canot figure out why. here is the code https://pastebin.com/dGDNMF2c

[edgy prism]

In the code I linked that works fine the problem is that if I set one slider to say 507 I can still increase the next slider to say 507 too the first time I move it

[rare basin]

where do you call the Jump function

[edgy prism]

Im checking its below 508 but I think I need to track the increase im just not sure how

[wet heath]

Creating particles on a specific surface when a raycast passes through

[blissful trail]

jump is being called from a seperate script managing my input system stuff but its not the problem, if i add a debug.log it tells me its being called but the code just isnt doing anything

[fierce shuttle]

Huh... I just tried to reproduce your scenario with a default scroll view and some buttons in the "content" and it seems scrolling while hovering (or selecting/having a button "focused") is default functionality, does the scroll stopping behavior happen for you in a blank scene with just a Canvas (and its accompanying EventSystem)?

[polar acorn]

Every time you call SetMovement you overwrite the velocity

[blissful trail]

oh so its overwriting not just the x and z velocity but y too?

[short hazel]

As long as you both check that the sum doesn't exceed 508 and correct the slider in the same frame, you won't see the difference.
You'd need a way to know which slider was just interacted with, so you can "clamp" it. Sum all the sliders except the one you just touched. If sum + sliderYouTouched.value > 508 then set value to 508 - sum. There might need to do a - 1 or + 1 somewhere to land on the 508 after the subtraction

[lone sable]

Yup. I'm also on a older version of Unity, so, it could possibly be related to that.

[fierce shuttle]

Strange, which version? I have an old project in 2018.3 I tested and seems mostly the same as newer versions

[blissful trail]

how would i make it so that i overwrite just the x and z velocity?

[edgy prism]

Ahhh yeah that makes a lot of sense, can I use pointer.EventData to get the slider I just touched? Not sure what the best way to do that would be

[short hazel]

Yeah that would be a way to do it

[lone sable]

Holdup. Just figured it out. When you said blank scene I just copied over to a blank scene and used the same buttons I already had. However, they have a Event Trigger on them. Having that Event Trigger on them, is what causes it to stop.

[blissful trail]

nevermind i figured it out thank you for your help digiholic!

❤️

[fierce shuttle]

Oh, interesting, glad you found the cause of the problem at least

[lone sable]

Yeah I'm just not sure how to fix that though...

I was using that to trigger mouse over/selection popups.

[short hazel]

Shame the OnValueChanged event of the slider (whatever it's named now) doesn't include which slider sent the event, just the new value.
or you can bind it from the code and do an ugly slider.OnValueChanged += (val) => SomeFunction(slider, val); and repeat that for each slider but it's dirty

[fierce shuttle]

Well a Button already inherits from Selectable which allows that functionality, you could either make a script that inherits from Button to access that functionality too, or maybe try using IPointerHandlers like IPointerEnterHandler, there is one for Exit, Click, Drag, etc as well

[edgy prism]

That would save me a headache if it was the case if you recommend getting the eventData that's the way ill do it. Thanks so much for your help!

[short hazel]

I guess that's the easiest solution, and if it works it works

[edgy prism]

Haha I haven't a clue how else id do it anyway so heres to hoping it works

[dense root]

How do you get over the fear of breaking things in code?

[polar acorn]

By getting good at fixing them

[dense root]

lol

[languid spire]

you cannot break things in code, there is always Ctrl+Z

[eternal needle]

version control and commiting often

using git is super easy to pickup these days now that all the good GUI's that exist, i use github desktop. Take a day to just experiment with it and how it works, and save yourself the fear of breaking things. If you arent using version control then you are always running the risk that something corrupts and you lose months of work

[dense root]

right

thanks

[vast vessel]

Also apparently unity has its own free version control thing now

You can enable it with a "link" button in the unity hub

On the left side of your project name

[eternal needle]

unity has had some version control things for awhile from what ive seen online, but really you're better off just using git

[vast vessel]

Yea ig so. It dosnt have alot of things that git has. For eg it dosnt have anything like gitignore. It saves every single .meta file in your project

[rich adder]

pretty sure it has some similiar thing

meta files are important

[eternal needle]

Git is pretty much the only tool you'll see used in every other aspect of CS

[languid spire]

if you are not commiting .metas to git you are in trouble

[vast vessel]

Why?

[rich adder]

because all your scripts would be unkown or missing

[languid spire]

where do you think references between objects are held?

[vast vessel]

Wont unity just auto generate them if any files are imported into a project?

[rich adder]

hence why if you move files in project from outside unity without moving the meta that goes with it unity takes a shit

[languid spire]

ha, ha, you wish

[vast vessel]

I thought they were only useful when you moved a file and so they wont be importent when uploading to git

[languid spire]

don't think, know

[eternal needle]

i mean unity will autogenerate them if they arent there, but you're gonna have a bad time if u delete them all

[polar acorn]

Well yeah, because it's supposed to

[polar acorn]

It'll auto-generate them... with no data, meaning all your references are now gone

[lone spear]

I have a player that is using the new Input System (not new now but hey) and all I want is the player to move left and right and up and down from a top/down view. Code here:

    Vector3 playerPosition = Vector3.zero;
    Vector2 _move;
    public float speed = 2;

    private void OnEnable()
    {
        controls.Enable();
    }

    private void OnDisable()
    {
        controls.Disable();
    }

    void Awake()
    {
        controls = new PlayerControls();
        controls.Player.Move.performed += ctx => _move = ctx.ReadValue<Vector2>();

    }

    void Update()
    {
        Debug.Log(_move.x + ", " + _move.y);
        transform.Translate(speed * Time.deltaTime * new Vector3(_move.y, this.transform.position.x, _move.x), Space.Self );
    }```

Produces this movement...

Which is plain wierd. Left/Right on keyboard is -1,0/1,0 in _move and Up/Down produces 0,-1/0,1 in _move...

Can anyone explain why it goes crazy like this?

[polar acorn]

It seems strange to use your x position as the Y value of your movement speed

[lone spear]

Turns out transform.Translate(speed * Time.deltaTime * new Vector3(_move.y, _move.x, 0.0f), Space.Self ); works nicely!

@polar acorn that's what I thought, and it turns out we're both right

[verbal dome]

Yeah, seems like your player's forward direction is actually its right direction

[lone spear]

@verbal dome perculiar- something from blender maybe?

[verbal dome]

You would need to fix it in blender, yes

The model's forward direction should be Y forward in blender

And you need to look up the correct settings when exporting from blender to unity, they use different coordinate systems

[spiral narwhal]

Is it possible to create presets that are saved for multiple projects? Because I almost never find myself in the need of creating animations with loop time set to true, always to false.

Kind of like overriding Unity settings

[ripe shard]

everything in project settings and preferences is saved to a file that you can copy to new projects but unity in general is not a tool where you have default settings for every toggle and value on each component, its more like a framework on top of which you build your own tools that would then optionally give you this kind of preset. Nevertheless in some areas, like say asset import, you get the option to save presets. but nothing like you describe there.

[spiral narwhal]

Ok

Thanks

[warped pendant]

does anyone know how to address the diagonal idle direction problem in top down 8 way movement?

basically, the player would have to simultaneously let go of the 2 cardinal directions making up the diagonal direction to get a diagonal idle direction, so what's the simplest logical answer to this problem?

[dense root]

what is the difference between the physics material being in the rigidbody or the box collider? it appears to have the same affect in my PONG game

[slender nymph]

not a code question, but i'm pretty sure that the difference is that on the collider it only affects that one collider but on the RB it affects all of the RB's colliders

[dense root]

Not sure what you mean by that

WDYM by affects all of the RB's colliders?

I know best practice is to put it in the Rigidbody2D since that's where physics are generally being applied but like I said in this simple case if I put it in BoxCollider2D it produces the same effect

[slender nymph]

every collider that is part of the rigidbody. in your case that is just the one on the same gameobject

child colliders of a rigidbody become part of the rigidbody's compound collider

[dense root]

Could you put it in simpler terms? I'm not quite comprehending

I guess the question is related to PONG how are they producing the same desired effect?

[slender nymph]

since you only have a single collider that is part of your rigidbody's compound collider it shouldn't make a difference which you apply it to

[dense root]

Huh? Player paddles have Box Colliders too

[slender nymph]

that's a separate collider obviously

[polar acorn]

Are they part of the same rigidbody

[dense root]

@polar acorn wdym

[polar acorn]

I mean what I said

Multiple colliders can be part of the same rigidbody

Are yours

[dense root]

Not that I'm aware of

[polar acorn]

Then there's no difference between setting the material on the collider or rigidbody

[slender nymph]

the obvious answer is no, they are not part of the same rigidbody because they are on completely separate objects

[dense root]

What's an instance of PONG where I would want to specifically set it to RigidBody2D and not BoxCollider2D?

And the other way around

[slender nymph]

why are you so hung up on pong having any relation to the question you've asked?

[polar acorn]

As stated, unless you have multiple colliders on the same rigidbody, there is no difference

[dense root]

@slender nymph it makes it easier to understand

[slender nymph]

the physics material will apply to either the single collider it is assigned to or every collider that is part of the rigidbody if it was assigned to a rigidbody instead of a specific collider

[dense root]

@polar acorn when would you have multiple colliders on the same rigidbody?

[polar acorn]

When you want a rigidbody to have multiple colliders

[slender nymph]

then the answer is it makes no fucking difference for the reasons already provided

[dense root]

Alright I think I'm getting it

Basically unless you have an instance where there are multiple colliders on the same rigidbody you can apply your physics material to either/or BoxCollider or RigidBody

[slender nymph]

it also helps reading the docs
https://docs.unity3d.com/ScriptReference/Rigidbody2D-sharedMaterial.html

The PhysicsMaterial2D that is applied to all Collider2D attached to this Rigidbody2D.

The PhysicsMaterial2D specified here is applied to all attached Collider2D unless the Collider2D specify their own PhysicsMaterial2D in Collider2D.sharedMaterial. If no Collider2D.sharedMaterial or Rigidbody2D.sharedMaterial is specified then the global PhysicsMaterial2D is used.

[dense root]

I'll give it a read, thank you

[nimble sorrel]

when working with coroutines can you put something after the while loop to have that thing happen when the while loop is over?

like so

[cosmic dagger]

yes, you can put what ever you want/need to. just try it out and check . . .

[summer stump]

Unless you yield break, destroy the object running the coroutine, StopAllCoroutines(), or StopCoroutine(cachedCoroutine), it will run all code just like normal

[weary moss]

FixedUpdate will run at the same speed doesn't matter if a person has 2 or 200fps right?

[ivory bobcat]

Fixed Update will occur the correct amount of time per second regardless of how many seconds have passed

https://docs.unity3d.com/Manual/ExecutionOrder.html

[weary moss]

so, framerate doesn't affect it?

[ivory bobcat]

What do you mean by frame rate doesn't affect it? Can you give an example?

[weary moss]

Update is linked to framerate, FixedUpdate just happens every couple of milliseconds

doesn't it?

[ivory bobcat]

If you acquired some delay of say ten seconds.. The Fixed Update loop will forcefully interpolate all of the lost frames.

[weary moss]

so it runs on it's own time?

[summer stump]

If the main thread is occupied, it can't do the FixedUpdate.
It will run as CLOSE to the physics rate as possible (50 times per second by default). This means it could even run twice per Update if needed, or once every other
It may not be spot on, but as Dalphat said, it will interpolate it

[ivory bobcat]

They are both dependent on frame but fixed update will interpolate lost frames

[weary moss]

so it's affected, but it has measures to make up for it?

[ivory bobcat]

The life cycle link I sent should have shown fixed update looping in the physics section until it has met it's accountable frames. It basically plays catch-up.

[weary moss]

so if the framerate is lower it will happen like 2 or three times in between frames

[ivory bobcat]

It can also not have occurred at all per frame if you've got more frames than what the physics frames were set to

[weary moss]

so it's independent of framerate

but is it affected by Time.timeScaled?

[ivory bobcat]

If you're getting less than 50 frames per second, it'll buffer extra calls to fixed update. If you're making more than 50 frames per second, there may be no physics call on certain frames.

[weary moss]

alright i finally got that

thx dude

[ivory bobcat]

https://docs.unity3d.com/ScriptReference/Time-timeScale.html

Note that changing the timeScale only takes effect on the following frames. How often MonoBehaviour.FixedUpdate is executed per frame depends on the timeScale.

Hey guys,

I am trying to understand and follow some stuff I found to save and load the game in a simple way, as for what I need is just a few information. When I have the button save or load to appear, the game is under cs Time.timeScale = 0;
Here I have 3 classes.
SaveSystem: https://paste.ofcode.org/NJJgpWpb7g9dxf5wMWQKFR
PlayerData: https://paste.ofcode.org/UvGhGSreUqLfATYqAbCpQ
Player: https://paste.ofcode.org/qcqkvy9JJkAkrvmpeRREZ8

It is not working and seems to be all good. any insights? Thank you!

[teal viper]

What exactly is not working and what steps did you take to debug it?

[solemn fractal]

I put some debug logs to see if the i was getting into the SaveGame and LoadGame methods inside the SaveSystem, and also to see if the data was being fetched etc.. all looks fine.. when I start the game, there is a intro screen where I have load.. and inside the game while it is running when I use ESC the game pause with Time.timeScale = 0; and I click the button save. Stop to play the game.. play again hit loading and thigs doesnt change

[teal viper]

I don't see any logs in the code you provided(aside from one when file is not found).

[solemn fractal]

True, because after I tested I deleted it

What I do to test is lose some HP

and save

close the game, open again, hit LOAD and nothing happens my hp should be instead of 30 should be 28

[teal viper]

You should keep the debugs when you ask for help. It makes it easier to see what you have attempted.

[solemn fractal]

No problem: https://paste.ofcode.org/xSja8GVKGTtLGF57X3mUNk

[teal viper]

There is a slight chance the issue is due to the binary formatter being obsolete.

Did you check the file that is getting saved? Does it have any contents?

Are there any errors in the console during saving/loading?

[solemn fractal]

Not sure where is this saving, I will look for it: cs string path = Application.persistentDataPath + "/player.save";

[solemn fractal]

no

[teal viper]

You can print it.

[solemn fractal]

Oh

I got a IOException Sharing violation on Path

[teal viper]

Open the console and take a proper screenshot. Do you always check for errors like that?

[solemn fractal]

Oh yes sorry how is the correct way?

You mean like that?

I used like that: cs string fileContents = File.ReadAllText(path); Debug.Log("Path: " + fileContents);

[rich adder]

unrelated , but do avoid BinaryFormatter btw

BinaryFormatter serialization is obsolete and should not be used. See https://aka.ms/binaryformatter for more information.
https://learn.microsoft.com/en-us/dotnet/api/system.runtime.serialization.formatters.binary.binaryformatter?view=net-8.0

[solemn fractal]

ok so which other method you advice me to use as a save?

[rich adder]

just json is fine

[solemn fractal]

Ohh ok, got it, thank you

[teal viper]

That's not what I recommend but ok.

For binary there is a binary writer.
Though, I feel like the issue is unrelated to it being obsolete(I don't think it is in the dot net version that unity uses).

[rich adder]

yeah def unrelated was just saying prob not even needed

[rich adder]

https://youtu.be/Q0_xreJMldM?si=ijvNzPufNrkcr7TY
Maybe you can peep this, there is no explanation but I go through it very quickly

[solemn fractal]

hmm ok, will try the json method. Thank u guys

[rich adder]

you're already saving json format no need to just use formatter

[rich adder]

btw what was the result of this log ? the path was prob wrong?

[solemn fractal]

same error as the one before, some violation stuff

[teal viper]

Sharing violation implies that something else is opening the file.

Or writing to it.

[rich adder]

this is how you died

interesting name

[solemn fractal]

hahaha

[teal viper]

I wonder if you put that line inside the stream block...

[rich adder]

You tried writealltext already ?

        PlayerData playerData = new PlayerData(player);

        var stringData = JsonUtility.ToJson(playerData);

        File.WriteAllText(path, stringData);```
@solemn fractal

[unreal imp]

Guys, how can I generate a raycast in front of an object and have the line also point in front as if it were the player's camera? here part of the specified code:

[solemn fractal]

WIll try, thank you!

[unreal imp]

            raycastOrigin = objectHolder.transform.position;
        raycastDirection = objectHolder.transform.forward;
        raycastLength = 3f;
        Debug.DrawRay(raycastOrigin, raycastDirection, Color.green, 3);
}

[wintry quarry]

looks fine

do note that a ray coming directly from the camera in the direction the camera is facing is not going to be visible from that camera

it will be a dimensionless point from the camera's perspective

[unreal imp]

Yes but I want to see it from the perspective of the scene when I pause the game

[wintry quarry]

to make it the correct length it should be Debug.DrawRay(raycastOrigin, raycastDirection * raycastLength, Color.green, 3); though

[wintry quarry]

what you have will work fine, what's wrong with it?

[unreal imp]

ahh duration xd

[wintry quarry]

Did you turn gizmos on?

[unreal imp]

im going to check,maybe is this

[wintry quarry]

Do note you're only drawing this once in Start

if the object moves after the start of the game, this won't be that helpful

[unreal imp]

ahhhh ahahaha

zhank you

nahhhhh (the green line is my raycast)

And if you're wondering, the object holder is in front of the player's camera as if it were a raycast

[rich adder]

Oh!! I know exactly why you were getting this

i just looked at your code again lol idk how i missed this

[weary moss]

is there a way to reliably sync a texture's offset speed with an object's transform speed?

[solemn fractal]

What?

[rich adder]

pretty sure that error is because you're trying to access the same file twice at same time

[solemn fractal]

why if i click one time in the btton?

[rich adder]

might be stream never cleaned properly

[teal viper]

They added that line later for debugging. While it most likely is the cause of the error, it's probably unrelated to the initial issue.

[solemn fractal]

But I am closing it

[rich adder]

ohh

[teal viper]

They're talking about the read all text line

[rich adder]

ops spoiled myself with using statements now 😅

you got it working now though right ? @solemn fractal

[solemn fractal]

Unfortunatelly not yet, i will need to sleep now, working from the office next 2 weeks, having few time during night to continue my mini game. Took some notes and will try more tomorrow and will let u guys know. thank you !!

[rich adder]

np! gl. if you need it , your entire method can just be this and should work 🙂

public static void SavePlayer(Player player)
    {
        string path = Application.persistentDataPath + "/player.save";
        Debug.Log(path);
        PlayerData playerData = new(player);
        var stringData = JsonUtility.ToJson(playerData);
        File.WriteAllText(path, stringData);
        Debug.Log("saved file to: " + path);
    }```

[short grove]

Is there a better way to detect multiple collision without using tag?

https://hatebin.com/rsqygolcjw

[queen adder]

I have a list of sounds, like 1 heal folder have 40 heal soundeffects, what's the best way to get a random healing sound? I was thinking of resources, or AudioClip[] HealingSounds, dunno what is better and may there be any better way?

[queen adder]

Use Physics.Overlaps

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircleAll.html

[short grove]

I'm not a professional but you can put it in a list and make a random function that selects number between 1 and the amount in the list

[queen adder]

if your game is 3d, use overlapsphere

[short grove]

Is 2d

[queen adder]

yea, i can make that implementation, i was asking for a better way since im always scred of making bigg collection of arrays

since it can lag the editor while open

[short grove]

Oh ok

[slender nymph]

too bad you aren't on 2023 since it has the convenient Random Audio Container

but just a scriptable object that has the array and a method to pick a random one would be fine. then anything that needs to play one of the sounds can reference the SO

[queen adder]

that's probably better yes, I dont even have to make a global library that grabs an audio

[halcyon osprey]

I wanna be able to make triggers-to-spawnpoints like in here, but I cannot find the right guide for it

[rich adder]

wdym like a scene swtich? what exactly you're struggling with ?

[amber spruce]

so im making my game have multiplayer and this is my script that does the players animations and the animation is messed up for multiplayer it doesnt sync and when one person does it both do

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.Netcode;

public class PlayerMovement : NetworkBehaviour

    public CharacterController2D controller;
    public Animator animator;

    public float runSpeed = 40f;

    // Update is called once per frame

        horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;

        animator.SetFloat("Speed", Mathf.Abs(horizontalMove));

[halcyon osprey]

Yeye like a scene switch, specifically having trouble with connecting it to a spawn, I'd like to not have the player just spawn in the middle of the scene

[cosmic dagger]

you need a script that starts when the scene is loaded with a reference to the spawn point. spawn your player at that spawn position . . .

[rich adder]

well if you have a certain Spawn point to go to give it a tag / script to look for ?

[timber tide]

Should make an effort to read the documentation for netcode because you're not going to get far without it

[rich adder]

you wanted pain.. welcome to pain

[queen adder]

Why do we have to type the parameter names of CreateAssetMenu btw? The suggestions doesnt even show after typing ,

For SO's

[rich adder]

you mean this?

[queen adder]

yea

[rich adder]

wdym doesn't show ? what code editor ur using?

should work like any other method

[fickle stump]

I'm having a tunnel vision right now... Why is my function not working when I'm ticking "is clicked" on runtime

[slender nymph]

where are you calling collectPlans

[wintry quarry]

because you're specifically checking that it's false (i.e. NOT ticked)

if (!isClicked)

[fickle stump]

basically what I'm trying to do is to follow this: https://youtu.be/cLzG1HDcM4s?si=iXZL7hf_fXq2DEQE&t=63 while making subtile changes like instead of doing an animation i want to unload my object

[wintry quarry]

well - it doesn't matter much what you're doing - the answer is you're checking if that variable is false before executing any of that code.

[static cedar]

From my understanding, it's because those are setters. Not optional constructor parameters.

[queen adder]

yea someone explained they're attribute thingies and not named params

[static cedar]

Not sure if it's possible in C# 9. But it's pretty similar to constructing new objects.

new MyObject() //these parenthesis is optional if you don't use a paramed constructor.
{
   ThisGetter = my_value,
   TTheOtherGetter = my_otherValue
};

The compiler will also recommend doing this by default. And if the setter is an init, you can only set it under those curly brackets.

[amber spruce]

where in there talks about animation because i have the rest setup thats really all i need to know

[rich adder]

https://docs-multiplayer.unity3d.com/netcode/current/components/networkanimator/

[timber tide]

you can search in the documents

[amber spruce]

so if im reading this right all i ahev to do for animations to sync is do instead of animator.SetTrigger("Jump"); i do networkAnimator.SetTrigger("Jump");

[copper perch]

I am about to release my game for internal testing.
With these 3 error messages is it just saying now that I just need to upload my game to the Play Store Console for Internal Testing and this is all I have left to do, and for the warnings, in my game there is no ads so the ads message does not apply to me right?
Also my game is 99cents to play for all 68 zombie bosses

[wintry quarry]

The ads message applies to you. The advertising id declaration has to be filled out for all apps.

#📱┃mobile would be the place for this BTW

[copper perch]

ahh thank you

🍻

[unreal imp]

@wintry quarry do you know about this? (srry for late response and reply you)

[tawdry mirage]

how do you name methods that do a lot at once? do you split them for clarity? i only need it to be done all at once. Maybe DoXDoYDoZ or DoX(bool doY, bool doZ) ?

[summer stump]

You want to reduce the reposibility of any method. If it's doing so much you aren't even sure what to name it, it may be a sign the method needs to be split

[wintry quarry]

Make methods that do only one thing

But conceptually, let's say x y and z are "put clothes in washer" "put clothes in dryer" "fold clothes" then a method that does all 3 would be called "do the laundry".

And conceptually it should call those 3 other methods to do the individual tasks

[tawdry mirage]

so you would make public method DoTheLaundry and three private methods?

[wintry quarry]

Maybe? Access modifiers aren't really part of the discussion at hand.

That's basically a whole separate topic

Called encapsulation

Basically the idea with both naming and encapsulation is that someone who wants the laundry to be done shouldn't necessarily care about the details of how it gets done

So it's much better to name it "DoLaundry" than "WashDryAndFoldClothes"

[tawdry mirage]

i have Ship that can contain ShipPart, ShipPart can be isAdded true or false, and before i add ShipPart to Ship i snap ShipPart to local grid, update it's XY, update it's internals XY, then i use it's internals XY to check if this position is already occupied inside Ship. Then add or not add. So, i name it PrepareForAddingToShip?

[summer stump]

What about TryAddPart

And make it check things first, if it can, do it

[tawdry mirage]

i already have TryAddPart

I have written it wrong. I snap, update xy in PrepareForAdding and i check XY in TryAddToShip

[summer stump]

Well, as they say, the two hardest parts in computer science are cache invalidation and naming things

I'm not sure why you don't check the position BEFORE snapping it and setting its local positions. Like just using a spatial query like checkbox or raycasting

[tawdry mirage]

i snap with step of 20m, 20m means 1 in XY

[polar acorn]

I've always heard it as "There are only two really difficult problems in computer science: Cache invalidation, naming things, and off-by-one errors"

[summer stump]

That is so much better

[digital lynx]

Hello, my game refuses to have my character jump for some reason. Does anyone know how to fix it?

[teal viper]

Might want to share some info on the issue(a video?) and relevant code instead of sharing a unity package.

ol

ok

note: I'm literally hammering the spacebar while i was walking

according to the console, the Isgrounded was always false. I don't know how to fix it.

Okay. So start from inspecting where Isgrounded is supposed to be set to true.

Then share the code properly:

How do I get my ball component and set the color via code?

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.CompareTag("Ball"))
        {
            if (!isPlayer1Goal)
            {
                Debug.Log("Player 1 Scored...");
                
                // TODO Create a serialized field
                GameObject.Find("Game Manager").GetComponent<GameManager>().Player1Scored();
            }
            else
            {
                Debug.Log("Player 2 Scored...");
                GameObject.Find("Game Manager").GetComponent<GameManager>().Player2Scored();
            }

            GameObject ball = GameObject.Find("Ball").GetComponent<Ball>();
            var ballRenderer = Ball.GetComponent<Renderer>();

            cubeRenderer.material.SetColor("Color", Color.red);
        }
    }

[teal viper]

Well, you're doing it with the cube renderer. Just do the same with the ball renderer.

[dense root]

Like this? I'm getting reference errors

var ballRenderer = Ball.GetComponent<Renderer>();

ballRenderer.material.SetColor("Color", Color.red);

How do I reference the ball component in code?

[teal viper]

What happened to the code that you shared previously with the Find method?

Also, if the colliding object is the ball, you can get the Ball component from it.

[teal viper]

Don't you see that it's a different variable?

Or rather a type name

[dense root]

I do now lol

[teal viper]

Case matters in programming

Usually

[dense root]

Hmm no compilation errors but it won't change the color

GameObject ball = GameObject.FindWithTag("Ball");

var ballRenderer = ball.GetComponent<Renderer>();

ballRenderer.material.SetColor("Color", Color.red);

Maybe it has to do with material being set instead of something else?

Something like .color

[teal viper]

Make sure the material/shader had a property with that name.

[dense root]

I'm just using the simple sprite renderer

[teal viper]

That's a sprite renderer. You should not modify the material then.

Instead of getting the base class, get the SpriteRenderer. It has a color property.

[dense root]

okay let me see what I can do

Got it thank you! @teal viper

How do I set it to a random color?

[teal viper]

Try googling first. It should find a docs page among the first results.

[dense root]

It points me to Random.ColorHSV which doesn't seem work with it

[slender sinew]

you aren't calling the function properly

it's a function call

read the error message thoroughly

you are trying to do color = Method; instead of color = Method();

[dense root]

Yeah I figured that out

Thanks all

[tawdry mirage]

isn't it too painful to look at?

if (shipPartTiles[forX, forY] != null) shipTiles[shipPartTiles[forX, forY].x + 50, shipPartTiles[forX, forY].y + 50] = shipPartTiles[forX, forY];

[sharp wyvern]

just a matter of opinion, but yes, hard to read

(IMO)

Tile part = shipPartTiles[forX, forY]; I'd make that, then use it in the if and following

[static cedar]

Yes.

[tawdry mirage]

better?

shipTileToAdd = shipPartTiles[forX, forY];
shipTileToAddX = shipTileToAdd.x + 50;
shipTileToAddY = shipTileToAdd.y + 50;
if (shipTileToAdd != null) shipTiles[shipTileToAddX, shipTileToAddY] = shipTileToAdd;

ahh null reference

When attempting to access an animation clip using AssetDatabase I get Failed to load "path" File may be corrupted or was serialized with a newer version of Unity. Our project has stayed on the same version and these animations can be handled and used in editor without issue...

Have no clue what could be going wrong

[sharp wyvern]

this way will handle the ifnull part, AND is still easy to read if (shipTileToAdd != null) shipTiles[shipTileToAdd.x+50, shipTileToAdd.y+50] = shipTileToAdd;

[tawdry mirage]

yeah, i did exactly this)

shipTileToAdd = shipPartTiles[forX, forY];
if (shipTileToAdd != null) shipTiles[shipTileToAdd.x + 50, shipTileToAdd.y + 50] = shipTileToAdd;

[sharp wyvern]

not sure if it will help with this issue, but deleting the library folder seems to clear up stuff that looks like some kinda corruption issue for me, fairly often.

[wary sable]

ill give that a try

[sharp wyvern]

warning- may take a longtime to rebuild

[sullen rock]

is it possible to somehow serialize this?
public int teleportIndex { get; set; }

[gaunt ice]

field:serializefield

[wary sable]

unfortunately getting the same issue

figured out the issue

when testing I was using an animation clip I had made in editor (meaning it was an actual .anim asset) whereas the files I was actually running the script on were .fbx despite them both being 'clips'.

so changing .anim to .fbx in the script solved it

[velvet herald]

Im trying to make a game where u can upgrade ur attack

And upgrading it would provide different properties

Like maybe a swing will add a spawn small projectiles to shoot

Or maybe it can reflect enemy bullets

If thats the case, should I use scriptable objects?

[wary sable]

that really depends on a lot of different things, but its good to note that you can't serialize SO's, so if and when you modify data like weapon level that will have to be stored elsewhere. With that said SO's are great for static properties / methods... So if you have an upgrade path that you want pre-defined you can have that all pre set in the SO.

[sullen rock]

serializefield does nothing

[velvet herald]

So lets say its more roguelike so ir can be random

Does that mean SOs arent odeal

[gaunt ice]

**field:**serializefield

https://danielilett.com/2021-08-16-bytesize-5-serialize-field/

[wary sable]

Sorry I completely skipped over that part my bad. Then yes scriptable objects would be great! Just keep in mind that if you want multiple instances of the same item with different levels you may still run into a bit of trouble.

[velvet herald]

So how should I approach it

Make multiple variations of th weapon with different properties?

[wary sable]

Depends… especially with inventory type stuff there isn’t really a great one size fits all answer. But generally in this case, if you are only going to have one of each weapon then SO’s will be great. If there is duplicates but only a set number of them, so long as that number is reasonable then SO’s would still be great. If you are planning on having the same weapon drop multiple times and you want the player to be able to have multiple of the same weapon with different levels you can still use SO’s but you may have to store the weapon level elsewhere like a POCO (plain old C sharp script)

[velvet herald]

I was planning to do smth like Hades

But instead of a selection to choose from we only have one

And as u progress in stages, you can choose upgrades that adds new properties to the weapon

Aside from that are boosts like movement speed and health

I think solid stats arent too dofficult to adjust

But the weapon additions are what im struggling with

[wary sable]

From the sounds of it Scriptable Objects for each of the weapons will be a solid system. As for upgrades that one can be tricky depending on how scalable and or universal you want things to be. I don’t know if I can give you any good answer for adding them to attacks as combat is a whole other ordeal that I’m just beginning to learn as well. But I would recommend starting by handling attacks from each SO where the attack code includes all of the effects / upgrades to the attacks locked behind if statements… that may not be the best system in the world but starting on something simple like that will get you moving in the right direction.

Unfortunately running into problems is really the only way to learn if something works or not. You just kinda have to go for it and throw stuff at the wall as sucky as it is

[blazing relic]

Can someone explain why this code doesn't print SUCCESS ?

{
    int seed = UnityEngine.Random.Range(1, int.MaxValue);
    System.Random oneInSix = new System.Random(seed);
    System.Random fiftyOneinSixtyTwo = new System.Random(seed);
    int roll1_6 = oneInSix.Next(0, 6);
    if (roll1_6 == 5)
    {
        int roll51_62_fourTimes = fiftyOneinSixtyTwo.Next(1, 63);
        if (roll51_62_fourTimes < 52)
        {
            roll51_62_fourTimes = fiftyOneinSixtyTwo.Next(1, 63);
            if (roll51_62_fourTimes < 52)
            {
                roll51_62_fourTimes = fiftyOneinSixtyTwo.Next(1, 63);
                if (roll51_62_fourTimes < 52)
                {
                    roll51_62_fourTimes = fiftyOneinSixtyTwo.Next(1, 63);
                    if (roll51_62_fourTimes < 52)
                    {
                        Debug.Log("SUCCESS!");
                    }
                }
            }
        }
    }
}```
Is my brain completely failing to grasp something or is this an issue with pseudo-random generation? I am trying to complete a 1/6 trial followed by 4 consecutive 50/62 trials. If my math is correct, which it may not be, I would expect about a 6% success rate, yet in 10,000 trials, Success is never printed. I feel i am definitely missing something regarding the way Random works...

[languid spire]

move your seeds outside of the for loop

[blazing relic]

My goal is to find a seed which will grant a success on its first attempt, so i need to check a new seed every-time... shouldnt this still have about the same chance of success? or does it somehow change the probability?

[languid spire]

if course it changes. what you are now trying to do is hit success on the very first go of a seed, the chances of this happening are virtually zero

to try what you want you need to change

int seed = UnityEngine.Random.Range(1, int.MaxValue);

to

int seed = i;

and it's all well and good just printing out SUCCESS!. You still have no idea how it got there so the whole exercise is pointless

[blazing relic]

It’s a simplification of a larger process

[blazing relic]

I don’t conceptually grasp how this is different but I’ll give it a go!

[blazing relic]

Yeah still no success

[languid spire]

the difference is it gives you control over what happens after. At the moment you have no clue as to what is being fed into the algorithm. So Garbage in, Garbage out

[languid spire]

And you still have no idea why it is not working

[blazing relic]

No

[languid spire]

Then ask yourself, how far down my logic do I get?

[blazing relic]

It shouldn’t matter if you stay with the same seed or change the seed every trial… if the Next() number is always random, then it should be just as likely to hit the success on the first trial as the next… no?

[languid spire]

yes, and the chances of that happening 5 times in succession are virtually zero

[blazing relic]

but im not trying to find a suitable seed 5 times in succession, just one suitable seed that works on 5 consecutive trials (6%)

[languid spire]

but that is not what your code is doing

[blazing relic]

well what would the code look like if thats what it was doing lol

[languid spire]

for (int i = 0; i < int.MaxValue; i++)
{
    int seed = i;

[blazing relic]

thats gonna run 2 billion times...

[gaunt ice]

2 billion iterations...
probably multithread it

[languid spire]

yep

[eternal needle]

you're trying to find a seed which does something very very very specific, this is gonna take time no matter what you do

[languid spire]

well, you return i if you hit Success

[blazing relic]

why do i need to run 2 billion times if my expected success is 6%?

[gaunt ice]

or looking at the algorithm on how the .Next output the int and try to find out the bit patterns

[languid spire]

you need to find which one of the 2 billion is the right one beacause you do not know

[craggy lava]

How do i make a firework and tool system like firework mainia

[gaunt ice]

what is firework mainia

[craggy lava]

A game on steam

[blazing relic]

its not that specific, its above 50% in 4 of the 5 trials

[eternal needle]

i dont think this will be feasible, random algorithms are designed against this kind of attack. would be analyzing a ton of numbers

[modest dust]

"Here, lemme give you a 10-page answer to that question real quick"

[blazing relic]

is my calculation of 6% wrong?

[modest dust]

How about something more specific, what exactly are you having a problem with?

[eternal needle]

🤷‍♂️ i dont know where u got 6% from in the first place tbh, what part is 6%

[gaunt ice]

it is not cryptosecurity random number generator so it should be possible? though it is still quite hard to reverse engineering

[eternal needle]

true but still would require some decent beginner knowledge to even know where to begin

[blazing relic]

closer to 7%

[gaunt ice]

is 51/62 indeed, so a bit higher

the range is [1,52) so 51 possible number, the min should be inclusive

[languid spire]

Also this is based on one seed. You need to know the seed value first

[blazing relic]

ok so i have a 7% chance based on one random seed?

if i repeat for a ton of different seed shouldnt i get a success after 100000 seeds?

[languid spire]

so stop changing the seed every loop, do what I first said and move that out of the loop

[blazing relic]

i did....

it didnt work

[languid spire]

right which means that your 7% is wrong

[blazing relic]

yes but why

[languid spire]

no idea, I'm not a mathematician

[eternal needle]

are u sure u saved your script or something after moving the code?

i tested this on a online compiler and i get success printed

[blazing relic]

whats your code?

[eternal needle]

quite literally the same thing you posted, with moving the seed part outside the loop

only changed debug.log and the unity random because im using an online compiler

[blazing relic]

yeah but that doesnt solve my problem

My goal is to find a seed which will grant a success on its first attempt, so i need to check a new seed every-time...

[languid spire]

which your code does not do but my amended for loop does

[blazing relic]

I tried what you suggested idk what you want me to say

sorry im getting sassy lol

yall just trying to help

but it doesnt make sense

[languid spire]

what you tried this? #💻┃code-beginner message

[blazing relic]

Not that one. 2 billion is gonna freeze up my machine

[languid spire]

coz thats the only way to find the seed you want

[blazing relic]

but why.... the success rate should be so high

need a math person to explain it to me

i need to go back to stats class

[languid spire]

logically.
If the success rate is 7%
and you want to hit it on the first go then...
the correct seed should be 7% of all possible seeds so...
you need to find that 7% within the int.MaxValue range
so how much of int.MaxValue is 7%?

[blazing relic]

about 140mill

lightbulb

[languid spire]

right so logically if you loop for 140m you should find 1 which works

[blazing relic]

it finally makes sense

lol

[languid spire]

assuming non random spread

[blazing relic]

ok im running it now 🤞

[keen dew]

Sorry but that makes no sense at all. If there's a 7% chance then running it 100 times gets you through on average 7 times, regardless of how many possible seeds there are. By the same logic if there's 100% chance to succeed on first try you'd need to loop through all int values to find one.

I think this is the problem:

    System.Random oneInSix = new System.Random(seed);
    System.Random fiftyOneinSixtyTwo = new System.Random(seed);

You're using the same seed twice. If oneInSix rolls high then fiftyOneinSixtyTwo also rolls high on the first go

[languid spire]

I'm not sure why he has 2 different randoms either

his probability calculation is surely based on using the same random seed for all throws

[eternal needle]

From experimenting actually, this seems like the perfect number choice to be impossible with what Nitku said. If the first number rolls 5, the second number is always 52 or higher..

[eternal needle]

just curious where have u come up with this problem that needs solving? Is this like some question you were given as a challenge online

[blazing relic]

this is it

[blazing relic]

this is the info i was missing

[blazing relic]

i have a game which uses seeded runs. I need a seed for the tutorial that meets certain criteria

[eternal needle]

Very unlucky that you needed the exact numbers that weren't possible with your code

[blazing relic]

lol yeah but i shouldve figured it out sooner

when i was first running it i was like why is the first number (after 1/6 trial) always high? but then i kinda got rabbitholed

[blazing relic]

big oof

[eternal needle]

I assume random.next uses decimals then and multiplies to get within the range specified, rolling a 5 from 0-6 would be 0.833 and above. 0.833*62 is just 52 if rounded up

[blazing relic]

damn thats brutal

woulda saved myself so much time if the numbers were just slightly different

it has to do with item droprates

but i wouldnt have learned 🤓

[eternal needle]

Guess it's good to know for my game too which relies on rng heavily

[vale blade]

how do I handle coroutines in non-monobehaviour classes?

i.e.
I have a GptApiClient class that I use to post a message and receive a response from the OpenAI API

what I did before was make GptApiClient : MonoBeheaviour and then access it through a singleton. that allowed me to start a coroutine for the PostMessage function.

Trying to refactor my code now so that GptApiClient is just a public static class that doesn't extend from MonoBehaviour, but now I'm confused as to how I would handle the coroutine?

[eternal needle]

you can run coroutines on another monobehaviour, but if that other object gets destroyed then itll also stop the coroutine I believe.

[blazing relic]

oml so many successful seeds 😭

[burnt vapor]

If you really don't want to use a MonoBehaviour, you could make an asynchronous Task

Though this does need to call back to the main thread

But you're better off having a Monobehaviour do it

But you can totally iterate the IEnumerator from a Coroutine yourself in a way, it just takes time to implement and I doubt it's any better

[eternal needle]

Are u just reusing the same one random instance now? I assume that's the easier fix for this. I was reading before 1 in 140m seeds and was thinking this makes no sense but had no other explanation why it didnt work lol

[burnt vapor]

Needing a Coroutine for a PostMessage is weird though. Can't you do this asynchronously rather than polling for a result?

[blazing relic]

no I just skip the first Random.Next() for the second random instance

The instances must stay separate cause they control different aspects of the game

so random instance 1 checks the first value and random instance 2 checks 2-5 values

[eternal needle]

I see, I guess that can be useful to get the same generation each time with a certain starting seed

[languid spire]

we use this kind of thing a lot in Casino games because it allows us to exactly tailor the win/lose chance of the game

[blazing relic]

my tutorial finally has the perfect seed for the start of the game :)

thanks all

[naive pumice]

Hi guys, i am building a linux build using IL2CPP on my Mac (intel chip) for a dedicated server, and it's taking forever on the Linking GameAssembly.so (x64). Is it normal ?

[rare basin]

is this a code related question?

[naive pumice]

not really but i could not find where else to post it, can you tell me please ?

[tawdry mirage]

cannot do that?

[static cedar]

No way around it.

Set it on Awake.

[tawdry mirage]

oh okay. That could be 150% quality of life

[static cedar]

Just replace it with { get; private set; } of course.

[burnt vapor]

Field initializers run before the class constructors so technically this does not exist yet

Not sure why you would need to do this since it looks like a bad dependency loop, but maybe you want to use a generic type instead?

[tawdry mirage]

i'm not sure, i'm just refactoring my code to make it look more clear and with less lines

[burnt vapor]

I see, why do you need this in this case?

[tawdry mirage]

ActorLogic will use this Actor later. ActorLogic had SetActor method and i wanted to remove it

yesterday it all was in Actor class, today i wanted to split my giant wall of text into several classes

ActorLogic will only exist inside Actor

[burnt vapor]

Right, usually something depends on another thing but it would not go into a loop like this

Because this is a way to get stuck with dependencies

So if both things depend on eachother maybe it should just be one class

Or maybe Actor should inherit from ActorLogic

[teal viper]

If you want to separate logic from data, it's usually the other way around: MonoBehaviour contains the logic, while a plain class is used for data.

[tawdry mirage]

Actor has logic related to basic things like moving, turning, shooting while ActorLogic has logic related to it's AI

i'm bad at organizing it)

[teal viper]

Might be better to name it appropriately then. Maybe even make it a separate MonoBehaviour.

[burnt vapor]

Then just make it an abstract class you can inherit from

And the logic class inherits itself from MonoBehaviour

[tawdry mirage]

do people usually spilt their big classes with inheritance?

[burnt vapor]

Well your class is a base class that contains movement and all that

You can also just keep it a separate class and emit events from it depending on how you move

Whatever you do, you should not have to make a looping dependency like this

[tawdry mirage]

if i call some method inherited from parent class, is it faster than calling some method from other class?

[burnt vapor]

Don't worry about performance

It's not something you should think of, especially not here

There are some specific rules but those are not related

[tawdry mirage]

what exactly is looping dependency? like if two classes depend on each other's methods?

[burnt vapor]

Yes

You should not need that because then it should just be a single class

Usually A depends on B, and B will emit events that A should then subscribe to

[vale blade]

the coroutine includes an Action<GptResponse> onResponseReceived as a parameter,
so it's basically

yield return request.SendWebRequest()
var response = JsonUtility.FromJson<GptResponse>(request.downloadHandler.text);
onResponseReceived.Invoke(response);```
does that make sense?

[burnt vapor]

JsonUtility 🤮

Right makes sense I guess, you're using the Unity web request system

[vale blade]

yeah

[vale blade]

I think that's more or less how you're supposed to do it according to
https://docs.unity3d.com/Manual/UnityWebRequest-SendingForm.html

[burnt vapor]

Eh I'm usually against these things, especially now that Unity has better support for Tasks so you could just use HttpClient

[rare basin]

that is deprecated iirc

the old web request system

Sometimes logs have added context to them. If you click on such a log, the context will be highlighted in your scene/project. Dunno if this particular log has it though.

[queen adder]

i want to make a game where a storm is created every 1/10000th frame. i have 2 scripts at the moment. 1 where i want to start the storm itself based on what type it is. but in my 2nd script i have the type of the storm that i want to give to the first script.

my question is, is it easier to just combine this into 1 script or is there a way for me to easily link these 2 scripts?

[timber tide]

I think you should revaluate how much you want to get done in a single frame

[queen adder]

quite new to unity and dont know how everything completely works. seems to be working fine atm. just want a way to link 2 scripts between one another or if i should do it in one script.

[rich adder]

up to you really how you do it, both are valid

[timber tide]

Oh, you want to spawn one for every 10000 or so frames that have passed, is that what you're doing.

[swift crag]

do you really care about frames, though

[timber tide]

or 10000 objects per frame, maybe I should make myself a coffee

[swift crag]

or do you care about time

You almost never measure durations in frames, since the player's framerate will be varying (and different players will experience different average framerates)

[queen adder]

yes it is

i have a 1 in 10.000 randomizer that gets pulled every update()

;-;

[wintry quarry]

it's very easy to have two scripts communicate with each other once you understand the basics of C# and Unity.

[queen adder]

maybe doesnt work that i usually work on arduino and other embedded systems that use a "loop()" function

[queen adder]

i understand c#, just not unity that well if im honest

[rich adder]

communicating between scripts isn't that much different in unity than standard c#

[gaunt ice]

unity update is running inside a loop

while(1){
  update() and other monobehaviour messages
}

[rich adder]

the only differences is monobehaviors + inspector

[queen adder]

yea this throws me off a little ngl

[rich adder]

basically any public/private serialized references of scripts/components can be linked in inspector

since monobehavior can't be created with new()

[queen adder]

so if i want to refer to another script, i can drag it into my other script using the inspector or what?

[rich adder]

unity does that when its on an object

[queen adder]

ahhh

[rich adder]

yea pretty much, you make the reference/field for it first then link it thru inspector 🙂

[queen adder]

ahh gotcha, thanks alot. ill go try that now

[wintry quarry]

Just be sure you understand the difference between a script (the script .cs file itself) and an instance of a script attached to a GameObject. It's the latter you will be dragging around into inspectors.

[queen adder]

yea no i got that. to me that translates over p well from c# itself

[swift crag]

you just need to reframe this in terms of a probability per second

If you want an event to happen once every 1000 seconds, I'm pretty sure that's just:

oh wait, it's not just that

if (Random.value < 0.001f * Time.deltaTime))

This is wrong. If Time.deltaTime was 1000, you'd have a 100% chance to trigger the event

(well, unless Random.value returned 1, which it can do: it's inclusive)

it's been a few years since i took that randomized algorithms class. i am bad at this

oh god i'm getting nerd sniped here

the objective is to, for a time interval, calculate how many events have occurred

it's easy to calculate the expectation (the average value), but I'm not so sure about randomly drawing

[swift crag]

this is probably irrelevant, though, since your game will be running at way more than... 0.001 FPS (:

it's a decent enough approximation

[cosmic quail]

isnt it better to use coroutine for this?

[swift crag]

That would be a reasonable choice! you'd just randomly pick a delay.

That sounds more consistent. The player wouldn't expect two rare events to occur back-to-back

what is this component?

[autumn tusk]

how would i make a prefab have a sprite then switch to an animation after colliding with an object in unity 2d

[rich adder]

animator

[autumn tusk]

please elaborate

[rich adder]

Animator controls what happens to sprite renderer

switching to animation would be as simple as switching state

[novel shoal]

public class airplanemovement : MonoBehaviour
{
public float speed;
public float turnspeed;
public float axisx;
public float axisy;
void Start()
{

}
void Update()
{
    axisx = Input.GetAxis("Horizontal");
    axisy = Input.GetAxis("Vertical");
    transform.Translate(Vector3.forward*speed*Time.deltaTime);
    transform.Rotate(0,axisy * Time.deltaTime * turnspeed,0);
    transform.Rotate(axisx * Time.deltaTime * turnspeed, 0, 0);
}

}
this script should change the direction of the plane:
with the horizontal axis it should change between left and right, with the vertical it should change the height, but it inverts them: with the vertical left and right and with the horizontal the height

[novel shoal]

i should remove void start btw

So, just started working with unity like a week ago. I already got experience in GameMaker, but i wanted to do more "professional" games.

Im doing a mobile game that everytime you click on the screen, you spawn a new unity thats called "ally". It'll already have enemys in the scene, and both allies and enemys will have an AI, so they will run to eachother and attack when they have range. The enemy will be stronger than the ally, so you will need to create a strategy to win (for example, click faster to spawn a lot of allies, or flank the enemys clicking on different locations of the screen).
Ok, the "gamedesign" is basically that. The playerr only job going to be click on the screen, and watch the war happens.

But im having an issue. Since in new to this, im having MAJOR issues at programming the attack damage, and the hp.

heres the code for both EnemyController and AllyController: https://paste.ofcode.org/wjd7SkmhDtTfuUYMfj2QZu

So i guess the problem is there im calling the damage a lot of times and its not proper working, the ally is not killing the enemy while the enemy can kill the ally without problem. PLEASE can someone help me?

Oh, and another thing, ignore the // comments, im Brazilian and I wrote the // comments on portuguese, my language. Just ignore.
And also ignore the animations code, i used a transition.

Please help me to get my game going correct ❤️

Sorry for the huge text wall guys

[rich adder]

lol we didn't need the whole backstory 😆

[blissful heart]

hahahahaha its better with the backstory so u guys can feel my pain

[rich adder]

nah im just jk but yeah its hard to read what the problem actually is

so the ally can't kill enemy right ?

[blissful heart]

i havent send the code for GameController, but is basically just instantiate when u click

[rich adder]

all the attacks and debugs are working ?

[blissful heart]

yeah thats right

[rich adder]

printing

ok

[blissful heart]

i cant send u a video of the game if u want

Hi, is there a way to retrieve the current focused go from the standalone input module component?

[timber tide]

currentSelectedGameobject?

or is focus a different attribute

[umbral bough]

currentSelectedGameobject from the EventSystem doesn't appear to be working on UI elements

[timber tide]

Ah, UI specifically I think I recall a method for that, but usually the event system has that info too.

maybe I could find it if unity decides to be nice and open one of my projects

https://docs.unity3d.com/ScriptReference/UIElements.Focusable.html

Ah, this maybe what I'm thinking of. Was using it for a hybrid keyboard w/ onscreen

[abstract finch]

I want to spawn some orbs after an enemy dies in a parabola arc until they hit the floor. Is it more performant to use code driven arcs rather than rigidbodies w/ gravity?

[timber tide]

if you're not using colliders for your first method than it would probably be more performative otherwise probably not too different.

actually non-kinematic rigidbodies would still have a lot more overhead so if you are spawning hundred of orbs then it's best to avoid it

[umbral bough]

I am not sure how I'd get the hovered object from that tbh

[timber tide]

Are you using a pointer

[abstract finch]

I see I could use colliders but also have them do overlap sphere even?
Heres what im trying to replicate

[umbral bough]

yes

[timber tide]

There's IPointerHandler for when you want to specifically call an event when you're over that specific UI element

[umbral bough]

yeah, wish I could use that

[timber tide]

oh, there's also probably a buffer you can read from for current hovered gameobject

[umbral bough]

I'd just use a regular unity event and then pass that object in the inspector

but our uni forces us to use visual scripting and I don't feel like living :/

ik that this isn't the visual scripting channel, that's why I asked a specific question about the thing that held data that I needed and it's fine if it's not possible to retrieve it, will find another way ig

[timber tide]

Hmm, there is IsPointerOverGameObject, but you may need to raycast yourself onto the UI and grab the element to compare or however you want to use it

[rare basin]

why can't you use IPointerEnter, IPointerExit?

and cache the last hovered UI object

oh okay didin't read the visual scripting part

[umbral bough]

I am using the event tirgger on pointer enter

[rare basin]

yea that's pretty much the same

[timber tide]

Right, you can actually ignore colliders on the orbs if you wanted to and just check collision with overlap if you want to. More control too like disabling checking when the object is set, ect.

[rare basin]

just cache the game object you've hovered

the do whatever you want with it

[umbral bough]

yeah, I was looking for a way to do that, how

[abstract finch]

sounds good thanks!

[umbral bough]

mao recommended rc which seems reasonable but I was hoping that it's possible to retrieve it from the standalone input cuz it has a focused object var but it is prob private

[rare basin]

implement the interfaces

make a "SelectionManager" singleton or something

and cache it there

whenever OnPointerEnter triggers

[timber tide]

yeah ive no clue about visual scripting beyond the vfx / shader graph haha

[rare basin]

for sure you can do this

can't do it from EvenSystem.current iirc

you either need, as Mao said, make a custom raycast (graphic raycast, not phyiscs raycast)

i think you can also do EventSystem.current.RaycastAll()

EventSystem.current.RaycastAll(new PointerEventData(EventSystem.current) { pointerId = -1 }, results);

        if (results.Length > 0)
        {
            GameObject hoveredObject = results[0].gameObject;
            Debug.Log("Hovered object: " + hoveredObject.name);
        }

[timber tide]

I would expect currentgameobject from the event system to work if you're hovering over buttons and stuff, or any UI element with selection interface implementation

[rare basin]

sth like that

[rare basin]

yea im surprised it doesnt, if we have "IsPointerOverGameObject()", why can't we cache that object we are "over"

[umbral bough]

well I attached the EventTrigger component to my texts but they don't get selected in the event system

and I do have my event system properly set up in the scene

[rare basin]

text components are not Selectable

so they cannot be selected

[umbral bough]

i see

[rare basin]

You need a Selectable inheriting component

such as Button, Slider, Dropdown, Input fields, toggle etc

[timber tide]

So in this case you'd raycast and compare against if it's selectable

oh wait, you're looking for a transform here. You'd want a rect transform.

better to grab by the type than transform values anyway

Get Current Selected GameObject -> Get ISelectable, or button if you only need that specific type.

[umbral bough]

well the issue is that even tho the element has a button component attached, es doesn't recognize it as a selected object :/

[modest barn]

Hi. What is the name of the library that fills the blank for using ___ for the TextMeshPro (TMP) library?

[SerializeField] TMP_DropDown dropDownObject;

I'm trying to do this but Unity says that it can't find the type TMP_DropDown so I suspect my library name is wrong. I've tried a few, like TMP, TMPro, TMPPro, etc. but none work.

Also struggling to find this information online (probably looking in the wrong places).

[polar acorn]

https://docs.unity3d.com/Packages/com.unity.textmeshpro@1.3/api/TMPro.html

[rich adder]

when you type TMP_ you get all the suggestions like namespace too

are you not?

[modest barn]

I tried that because I sw it at the link @polar acorn sent, but it still doesn't work?

[polar acorn]

Do you have it installed

[modest barn]

Oh 🤦

[rich adder]

[modest barn]

DropDown vs Dropdown. Sorry guys

[polar acorn]

.value

[modest barn]

Never mind, still getting the same error.

[rich adder]

what error

[modest barn]

About to send 🙂

[polar acorn]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/script-Slider.html

[modest barn]

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

public class DropDown
{
    public DropDown()
    {

    }

    [SerializeField] TMP_Dropown dropDownObject;

My code ^^. The error:

CS0246: The type or namespace name 'TMP_Dropown' could not be found (are you missing a using directive or an assembly reference?)

Line 13 is the line where I serialize and define dropDownObject.

[polar acorn]

What's a Dropown

[modest barn]

Oh ffs

Can't believe myself sometimes. Thanks

[rich adder]

what "doesn't work" mean

[polar acorn]

Neither of those are .value

If you need the value from a slider, .value is how you get the value of a slider

[modest barn]

'Dropdown' is missing the class attribute 'ExtensionOfNativeClass'!

What's this?

https://docs.unity3d.com/Packages/com.unity.textmeshpro@2.0/api/TMPro.TMP_Dropdown.html
Can't find it here

[wintry quarry]

You probably wrote your own class called Dropdown, attached it to a GameObject, and then later removed the MonoBehaviour part from it?

[wintry quarry]

This is TMP_Dropdown, not related to your error

[modest barn]

I renamed the script and changed the class name and constructor name to match the renamed script

And it did that

But I've done that a bunch of times before, and it always work.

[wintry quarry]

There should NOT be any constructors on a MonoBehaviour

show what you're trying to do

[polar acorn]

If it has a constructor then that means it's not a monobehaviour, your error shows you've tried to add it as a component to something anyway

[modest barn]

It's not a MonoBehaviour

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

public class Dropdown
{
    public Dropdown()
    {

    }

    [SerializeField] TMP_Dropdown dropDownObject;
    TMP_Text dropDownValue;
    
    void OnValueChanged()
    {
        dropDownValue = dropDownObject.captionText;
    }
}

[polar acorn]

So, this is not a component. You cannot add this to any GameObjects

[modest barn]

Ahh that'll be the issue then. Can I still use it in a TMP_Dropdown gameobject's OnValueChanged() function, for example? Where I drag the script in and select a method to be ran.

[polar acorn]

No

How would you reference an instance of it?

Also probably not a good idea to name a class the same thing as a Unity component

[modest barn]

y x = new y();, right? Removing MonoBehaviour allows that I thought

[polar acorn]

How would you expect to use that in the inspector though

[modest barn]

I just want the script's OnValueChanged() method to be run whenever the TMP_Dropdown object has its value changed. Then I would need to access the text of the selection made, which is within the captionText attribute. I would need the class to be instantiated for that, right?

[rich adder]

desnt dropdown already have its own ValueChanged you can sub to another MB?

whats the point of this class being a poco

[modest barn]

Poco? Sorry, new to Unity 🙂

[rich adder]

plain old c# object

[modest barn]

Haha

[polar acorn]

"Plain ol' C# Object" as in, not a monobehaviour or component or anything

[modest barn]

And what do you mean 'sub'?

[rich adder]

https://docs.unity3d.com/Packages/com.unity.textmeshpro@2.0/api/TMPro.TMP_Dropdown.html
this already has event

[rich adder]

subscribe to an event

ie run this method when value changes on dropdown

there are multiple events too

[modest barn]

So I've created a method in a script and I've added that as a component to the TMP_Dropdown GameObject. Is that what you mean by subscribing to an event?

[modest barn]

I only need that one for now, so it hopefully won't be that difficult.

[polar acorn]

Subscribing to an event would be adding the function you want to call to the OnValueChanged callback on the TMP Dropdown itself

[modest barn]

Yes I believe I did that. Let me send you a screenshot.
