If you're using the default Button, when you click it, in the Inspector there should be a field On Click().

[cobalt flare]

yup

[slender nymph]

so do you plan to provide any information or are we just supposed to guess at what your issue is?

[cobalt flare]

i need help with buttons i cant click them therefore cant test;

when i click

it doesnt work

[slender nymph]

and, again, this is a code channel.

[cobalt flare]

and

[slender nymph]

and if the issue is not code related, why are you posting it in a code channel

[lean pelican]

If you're gonna be so insistent about it, you could at least point them to the correct channel.

[slender nymph]

#🔎┃find-a-channel exists, they can find the relevant channel theirself

they should also maybe bother reading #854851968446365696 to see what they should include when asking for help instead of dropping some vague issue and expecting people to know what they need to do

[golden kelp]

Should I use VS code or visual studio 2022

[slender nymph]

visual studio is far better than vs code, but ultimately it's up to you which you choose to use

[golden kelp]

Ok

Thx

[fast fern]

https://paste.mod.gg/wzcbhxldqklt/0

I added comments to explain what did and did not work

[slender nymph]

if the second didn't work then you simply aren't calling the RollCredits method

[fast fern]

isn't it supposed to call it when the if statement condition is fulfilled?

[slender nymph]

The if statement is never even evaluated if you don't call the RollCredits method

[fast fern]

I'm new to this, sorry if I ask a lot of questions reeeee

[fast fern]

how did the other function get ecaluated then?

[slender nymph]

You're calling that method somewhere

[fast fern]

and why does this failed one not?

[slender nymph]

If you don't understand how methods work then start with the beginner c# courses pinned in this channel

[fast fern]

oki, I do feel like my fundamentals are cooked

thanks for your time tho, I appreciate it

[chrome apex]

I know how to do this in multiple ways but I just wanna get an opinion on the optimal way cause I wanna learn good practices

so after a special hit, an object should play its particle system and then get deactivated

the issue being that the particles will stop after deactivation

so, do I just disable its sprite renderer and collider while particles are playing?

do I put the particle system as a parent and leave it running?

do I have an unrelated particle system object not as a child and play that?

what do you think would be a good way to achieve this?

nvm, I decided to go the disable, then enable sprite renderer and collider route

[thick bronze]

Can someone explain to me the difference and relationship between GameObjects, MonoBehaviours and the new stuff in DOTS. What I’m confused over mostly (especially when reading or watching tutorials) is what is part of the recent transition and what came before.

[bitter apex]

my gameobject isn't experiencing gravity, what can I look at to troubleshoot? I've used scripts to make sure that the freezex and freezey constraints are off now, but they still aren't experiencing gravity

[bitter apex]

must just be a problem with what I'm doing elsewhere. it works fine if i disable it manually in the first scene, but in the second scene that I've been having issues with it doesn't experience gravity no matter what.

It's incredibly bizarre, every now and again when I run it my objects will fall and experience gravity, and other times they just will not experience anything lmfao

[verbal dome]

Does it have an animator or a script that could be modifying its RB or transform?

[bitter apex]

when the scene is loaded a grid is created, and then that gameobject is moved directly to a position within that grid. then it is unfrozen. that's about all that happens (and can happen) to its transform

i think it might be an issue with me moving it directly to a position or something, because if i move it myself it then starts experiencing gravity again

i've got an idea for a temporary fix anyways, i'll just use that for now.

[runic lance]

you can think of them as two independent systems, MonoBehaviours are the standard way of working with Unity and DOTS is the new way (ECS way) — not necessarily the new standard.
DOTS was made with high performance in mind and it was built upon the existing infra structure, so you'll find a few shortcoming with the editor integration and ease of use, like having to bake components and sometimes interact with the MonoBehaviour landscape. But it should provide great performance, especially when working with lots of entities, compared to MonoBehaviours.

DOTS adds a lot of complexity and uses some advanced C# features, so I wouldn't recommend it for starting with Unity. Most people won't need it anyway.

[verbal dome]

Wdym with the first part?

Prefabs can't reference scene objects, is that what you meant

An object always knows about its parent no matter what it is

[mossy depot]

How do i fix this?

[robust harness]

It should be move.y instead of playerVelocity.y (is it supposed to be a reference to a script or something???)

[verbal dome]

What is "private playervelocity move" supposed to be?

[wintry quarry]

can anyone help me on this issue

the setbool command is not working

[cosmic dagger]

The error says it does not exist . . .

You are trying to access the method from the class itself, instead of an instance of the class . . .

Only static methods are accessed from the class (like in your code). An instance method must be accessed from an instance of that class . . .

hey guys, trying to do this unity.learn challenge but the text never changes nor the particles play, what can I do to fix this?

[wintry quarry]

Double check your logic around line 40

Walk through it in your head

What you have doesn't make sense

[compact stag]

i might re-do it since this code isnt mine, you're supposed to just debug it-

[wintry quarry]

Yes debug it

Use debug.log

[compact stag]

on line 40? alright

[red igloo]

I'm having trouble learning C# I don't want to have a habit watching too many tutorials all the time. If you guys were in my boat what would you do? Im mostly interested in making 3D fps games

[verbal dome]

Every now and then try to make something without watching tutorials

This forces you to think and solve problems by yourself instead of following a 1-on-1 guide

My main tip is don't use code that you don't understand

[red igloo]

How tho?? I am a noobie at coding and if I want to make something I have no idea how to

[verbal dome]

By using the skills that you learned from the tutorials!

Did you try the Unity Learn pathways or have you just done youtube tutorials?

[burnt vapor]

Animation animation = new Animation();
This line is created locally in Awake and will no longer exist as soon as the method is exited. If you want to use it you will have to assign it to a field in the class, much like speed and body.
The error is because Animation is a class whereas you want to use animation after you properly assigned it.
That said, you generally don't make a new instance of the animation like this.

[red igloo]

I tried doing unity learn and I will say that aint for me. I know how to use unity editor itself. I tried watching youtube tutorials and some of them are just confusing and they dont explain in detail what this does and how to use it correctly etc.

[verbal dome]

I believe that is the legacy Animation component, and yeah you should never create components with the new keyword, use AddComponent instead @lament marsh

[burnt vapor]

I never really used these things so it's hard to comment on if it's still relevant 😄

[verbal dome]

This code really looks like you want to use Animator instead, though

Yeah you are definitely confusing Animator with Animation here

[lean pelican]

The single best advice I got from a youtube video is to take some (not overly ambitious) idea and proceed to break it down in ever smaller and more primitive tasks until it either becomes a thing you know, or a single method/concept you can look into.

Like, say, I want my a character to move in a sidescroller. That breaks down into
How do I make my character into a GameObject and give it collision/gravity so it can stand on the floor.
How do I make a floor with collision.
How do I make a GameObject move. (For starters just by primitively setting the velocity, acceleration is its own thing)
How do I take inputs from the player.
Put all that together and you have a character that can run, jump and land on the ground when the player presses keys.

And once you figure out all the parts, you figured out 'How do I make a moving character', which is a new moving part you can use from then on. And if you understood every individual part instead of copy-pasting, you should understand the whole result too.

https://www.youtube.com/watch?v=h1o5UzKfZcQ

He's not actually using Unity, but the concept is universal enough.

[lament marsh]

@verbal dome@burnt vapor@cosmic dagger thank you guys for your comments i'll try to apply your advices when i'll come back home

[thick bronze]

Does anyone have a starter template for making it work with DOTS, Netcode and 2d (tilemaps, sprites, etc)

[red igloo]

Hey man this was really good advice, I decided to just take baby steps and just made something simple, With no help at all and only using unity documentation I made a cube move by pressing W.

[lean pelican]

Happy to help^^

[fleet venture]

Should i be using Math or Mathf?

[brave compass]

Both work and in most cases Mathf just calls Math, but it uses float instead of double, so Mathf is more convenient to use when you are using float.

[thick bronze]

Can someone please point me to an entrypoint on how to launch a 2d project using dots?

[fleet venture]

ah okay ye i use float

[golden kelp]

Should I use jetbrains rider or visual studio 2022

Or vs code

[red igloo]

I want my cube to move when holding down W but when I hold down W the cube moves forward once then stops.

[golden kelp]

Idk man

There are too many

Can someone please help 🙏 🙏 🙏

Please tell me what is good for unity Should I use jetbrains rider or visual studio 2022

[visual linden]

GetKeyDown if only True for the frame during which the key was pressed (down).
You can use GetKey instead, which returns true every frame the key is pressed (continuously).

[iron wind]

I'd recommend Rider

[golden kelp]

Can u explain all the good things rider has

[timber tide]

pretty IDE, more hints than the VS-Unity plugin. It also provides some neat attributes for the IDE itself to throw warnings such as requiring to use return values of the methods, and stuff like that.

Macro stuff seems easy to setup too, but I didn't touch that much.

[swift crag]

I switched from VSCode to Rider a half-year ago or so

[timber tide]

Also you've got vs code which is just a lighter weight VS and I've been using it since 6 release.

[swift crag]

Rider is a lot more comparable to Visual Studio, since it's a purpose-built IDE

it offers way more code inspections and transformations

it also understands ShaderLab, which is a godsend

[timber tide]

there was some shaderlab plugin for vs I saw on reddit a few weeks ago, claiming to have some built-in documentation and things like that:
https://old.reddit.com/r/Unity3D/comments/1ianimq/first_complete_unity_shader_tool_vscode
Looks promising

[golden kelp]

So as a begginer I need to download rider

[timber tide]

VS, VScode, Rider. I wouldn't worry too much right now, but these all have some support with Unity

[verbal dome]

There is also System.MathF for floats btw

Doesnt really matter which one you use though

[bright zodiac]

No, dont use the System.MathF in Unity, they're not hardware accellerated by IL2CPP... unless you want a really terrible perf

[swift crag]

It's my recommendation, at least, especially now that it has a free personal license

[bright zodiac]

not until CoreCLR is official in Unity

[swift crag]

that makes sense -- the IL2CPP compiler recognizes uses of UnityEngine.Mathf and replaces them with intrinsics

https://discussions.unity.com/t/unityengine-mathf-should-use-system-mathf/858423

neat

[bright zodiac]

yeah

[swift crag]

IL2CPP is kind of bonkers

to use the technical term

[bright zodiac]

when CoreCLR finally official, none of us unity peasants would use Vector3/4/2
Vector<T> all the way! the simd way!

[tiny rock]

Hello, what could be possibly wrong?

[ripe shard]

you could provide more context on when it happens

[tiny rock]

thats when i build the scripts, not even starting the game

[lean pelican]

If I have a method that takes multiple parameters with default values.

PlaySFXClip(AudioClip clip, Vector3 pos =new Vector3(), float volume = 1f, bool persist = false)

If I try to call PlaySFXClip(myClip, true) the compiler (somewhat understandably) complains about being unable to convert bool to Vector3.

I figured out to solve it by just changing the order in the signature, putting 'persist' as the second argument (or obviously I could just put in the default value when calling the function, but that seems a little counterproductive), But I'd like to know if there's a way to call a function like this while 'leaving out' some arguments with default values but passing others?

[ripe shard]

Foo(argName: value)
Details:
https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/named-and-optional-arguments

[lean pelican]

So it would be PlaySFXClip(myClip, persist:true) ?

[ripe shard]

yes

[feral moon]

Why my camera doesn't it go down with the character?

Code of character: https://hastebin.com/share/ebuleyizuz.csharp
Code of camera: https://hastebin.com/share/zepehayamo.java

[lean pelican]

I see, thanks^^

[hexed swallow]

Looks like the camera is atached to the player. When the player jumps it's object actually jumps, however when it crouches the object does not move down, it just shrinks the capusle.
My recomendation in this current setup is to programatically move the camera down when crouched

[feral moon]

What I should be do?

[hexed swallow]

I'm not familiarized with your current setup, but you could create a function on your camera script to "crouch", basically just move the camera down, and another to reverse it. Then in your player controller, call the camera "crouch" and "uncrouch" functions when the character does these actions

[fleet venture]

I have a MouseUp event but it also seems to fire if the mouse isnt actually on the object, how can i fix this?

i thought maybe somthign with the collider

[hexed swallow]

I don't think English is their main language so I would not be surprised if programatically move the camera down when crouched did not get my point across.

[hexed swallow]

Could you share a code snippet?

[fleet venture]

sure

private void MouseUp()
{
    //if (GetComponent<Collider2D>())
    _dragging = false;
    if (Input.mousePosition.x < ScrollWidth)
    {
        Destroy(gameObject);
        return;
    }
    transform.position = new Vector3(transform.position.x, transform.position.y, 100);
}```

though

i am honestly not sure where thats getting called from

if (Input.GetMouseButtonUp(0)) MouseUp();

ye thats the issue

im not using the event

because that didnt work

i remember now

[hexed swallow]

I mean if this is in an update void this should work, but It also has 0 detection over what object the mouse is pointed at. If any object with that code is on your sceene it will fire when the mouse button is released, regardless of mouse position

[fleet venture]

ye im asking how do i check what object it points at

i need it to only fire if the mouse is over the object the script is attached too

[hexed swallow]

You could check it with a Camera.ScreenToPointRay (If i'm not wrong)

[fleet venture]

but idk how to do that

okay ill try that

[hexed swallow]

If I was to do this, I'd probably have the following setup:
Have a single emptry object in the sceene fire a Camera.ScreenToPointRay on update. That will give you the mouse hovered object without every single object checking for itself. Then check if that object is of your "hoverable" type (by tag or by checking if it has a certain script attached) and set a bool like isBeingHovered true in the hovered object. In the hovered object script add a isBeingHovered check inside the same if:

if (Input.GetMouseButtonUp(0) && isBeingHovered) MouseUp();

If you are not concerned about optimization you can have the screen check on every individual object, but I think this is a cleener way to do it

Also, add a currentHoveredObject varaible to your hovering detection script to make sure you can set isBeingHovered to false when unhovering an object

[fleet venture]

So should that be done in like my GameManagwr?

[hexed swallow]

For example. I usually like to create separate scripts to make each one more readable, but whether you add it to an existing script or object is your choice. Adding it to a gameManager object does seem like a good idea tho. TL,DR: So yeah xdd

[fleet venture]

I don’t quite get how it would work

Because it should do that check in update right?

Only when the mouse button is released

But then how do I make sure it first does that check in GameManager before it does them in the objects

[wide fable]

not sure if this is the channel i use to ask for what would be smarter to do but i want to make a party system but im not sure if i should have like prefabs for each character or use a script that determines multiple characters that gets applied to gameobjects that get made on runtime

[rich adder]

depends on many aspects, how complex its going to be, how many different components will be applied

prefab is always a good choice either way, they can be a good "template" to work with , combine that with data from maybe an SO and you have pretty modular setup

[wide fable]

alright thanks

[feral moon]

Maybe you can help me or somebody? I need to make sure that the camera is the same as when moving...

It's just that when I'm standing, for some reason - the camera moves away somewhere.

Here code of movement: https://hastebin.com/share/yiteresuxi.csharp
Code of camera: https://hastebin.com/share/yorebimiqo.java

[hexed swallow]

Might have to do with the shakeoffset, I'm not sure

[feral moon]

Maybe...

[timber tide]

Put the player model on its own layer and cull that from the camera

oh wait yeah I see what you mean

freaking KCC script so large lol

But it should work out of the box, so it must be something you've touched

[void dawn]

i dont know what im doing

[polar acorn]

What is the specific problem, I just kind of see you clicking on prefabs

[void dawn]

can you hear my voice in the video ?

[polar acorn]

No, I'm at work, my discord is muted

[void dawn]

oh sorry , i didnt know that

let me tell you then, i have this universal script for my weapons right, and i need to put 3 main things in the fields , where the cross hair will be , the ammo counter, and the player camera , but when i drag these things into said fields , it just wont work

thats when i add something from the scene

[hexed swallow]

It looks like maybe you have the wrong fields in your script, are you sure that the "camera" field is a camera field of the same type thatr your player camera has? same for the text

[polar acorn]

What does "won't work" mean

[rich adder]

you cannot add scene components to prefabs

[void dawn]

i will check that

[void dawn]

i didnt know that

[hexed swallow]

this aswell, but it does look like the prefabs are in the scene

[rich adder]

but looks like they edited the original not the instance in the hierarchy

[void dawn]

well , what exactly should i do then ?

[rich adder]

https://unity.huh.how/references/prefabs-referencing-components
ideally you pass that when you have the actual instance in the scene

[hexed swallow]

Oh yeah mb, the camera was in the scene, idk why I confused that xdd

[rich adder]

is the player supposed to hold those weapons?
you can also consider just having them all on the player ready and just enable/disable them as needed, this way you could link already in scene components

otherwise when you create the weapon/grab it you need to pass it the required references being held by whatever is already in-scene

[silk frigate]

Hello, can you tell me how to get around this error? Without renaming, deleting, or moving them. I have a conflict between two identical ".dll" libraries. And I definitely need them in both "Assets/Plugins" and "Library/PackageCache".

How do I understand this can be done through ".asmdef"?

Eliminate the conflict of two identical libraries.

[lofty sequoia]

what are the dll's called?

[wintry quarry]

show the actual error

[silk frigate]

Unity.RenderPipelines.Universal.Runtime

[rich adder]

thats a namespace, not an error..

[lofty sequoia]

Why do you need the URP dll in Assets/Plugins and the package cache?

I would delete the one in Assets/Plugins as that's for custom plugins. If you are a beginner I doubt that's what you're trying to accomplish

[severe onyx]

does Unity support giving one component of text in the UI different colours per line? or do I need to have each line be a different text component if I want that?

[rich adder]

you can

[rocky canyon]

tmpro is a mesh.. so im sure its possible

[edgy tangle]

You can use rich text tags

[rich adder]

you need rich text

[rocky canyon]

or simply that yes ^

[severe onyx]

oh yeah I just googled this question wrong

[rocky canyon]

it wouldn't be gradient or anything..

[severe onyx]

immediately found the answer after posting here

I need to stop doing that

lol

thank you though!

[rocky canyon]

you get google answers here too as responses..
usually they come with pre-packed opinions tho..

straight is less bias'd

@rich adder does that vscode feature u show come packed into one of the dependencies of it?

i have to re-install code and i removed alot but im not sure what plug-ins are left hanging around..

and would it conflict w/ other plugins?

[rich adder]

i believe its just part of the new dotnet tools update ?

[rocky canyon]

the tools or the actual sdk?

[rich adder]

https://github.com/microsoft/vscode-dotnettools/issues/370#issuecomment-2648653306 Message says 1.1.0 idk what that is lol

[rocky canyon]

ohh okay 🙏

[rich adder]

Im checking the extensions and some of them are higher than that version so I'm gonna double check by removing the third party one

[rocky canyon]

gotcha.. i couldn't find the cache folder for vscode.. soo i didnt check if the extensions were gone..

im assuming when i sign in they'll still be selected tho or w/e

[golden oxide]

hello i have a question of dotween. it doesn't seem to the RB.DoJump function seem to move not using the velocity. I'm wondering if their a way to get the increasing velocity so that i can properly animate the enemy jumping up and falling down (or a different tween library , even lerp if theirs a way )

[rocky canyon]

what does the documentation say about rb tweens?

[rich adder]

oh shit... it working
and its not even part of the snippets, an actual method as MB shows up

[rocky canyon]

interesting

byebye 👋

[rich adder]

this gets ride of weird issues when you accidentally tab and have it twice

[rocky canyon]

yea. that was soo annoying..

if u typed void to get to OnTrigger instead of OnTrig..

ud get void void OnTrig..

[rich adder]

I still need that beast for MAUI cause its still sketchy on vsc sadly

[rocky canyon]

lol.. i see that ur conditioned

[rocky canyon]

oh it'll be in teh shadows

def not me default anymore

i had to reinstall for reasons..
i uninstalled both vscode and vsstudio and rider
and all the distrubutables and
cleared as much cache as i could

[rich adder]

yeah it barely sweats 200mb ram for me

[rocky canyon]

i've reinstalled vsstudio just for the hub's sake.. now im on to greener pastures

[golden oxide]

here the link to it i can't send a direct link to RB one but it boldly labeled https://dotween.demigiant.com/documentation.php

[rocky canyon]

no worries

and ur code?

show as much thats relevant w/ the rigidbody

[rocky canyon]

tbh, vsstudio isn't all that bad

[slender nymph]

but did you read it to see how it moves the rigidbody?

[rocky canyon]

i am confidently assuming they did

waiting on code to confirm

[golden oxide]

it just does this at the start method: Context.RB.DOJump(Context.Player.transform.position,1,1,05f,true) and i check the velocity in the update: if(Context.RB.velocity.y == 0 )
{
jumpDone = true;
}
if(Context.RB.velocity.y > .1f)
{
Debug.Log("jumping");
}
if (Context.RB.velocity.y < -.1f)
{
Debug.Log("falling");
}

[silk frigate]

This option doesn't suit me. There would be a way to isolate them. So that they don't interfere with each other. Because in my MonoScript in Assembly this is the .dll library specified

[rich adder]

yeah the newer updates are more stable, having more than 2 VS open it would crash for me, what made me give up on it though was namespaces/references breaking for no reason

[rocky canyon]

use ` to send little codeblocks like that

[slender nymph]

Rigidbody

These shortcuts use rigidbody's MovePosition/MoveRotation methods in the background, to correctly animate things related to physics objects.

they do not change the velocity

[golden oxide]

ok thank ill use that

[golden oxide]

ok thanks ill try a different way for calculating enemy jumps

[rocky canyon]

you could probably use the D0Tween.To() and tween the currentVelocity

[golden oxide]

ill try that thanks

[summer thorn]

Is there a way to cross-reference code within scripts? I want a container for utility methods

[rocky canyon]

simply..

if u want utility methods u can just make a static class of them

YourNameSpace.Utils.DoFunction();

or using YourNameSpace;
Utils.DoFunction();

[wintry quarry]

Be more specific about what "cross reference" means?

[rocky canyon]

but yea i brushed off the beginning of that question lol ❓

[summer thorn]

So variables declared are shared across scripts already?

[wintry quarry]

A variable declared in a class belongs to an individual instance of that class.
Unless it's static

Static variables belong to the class itself

[summer thorn]

In script A I want a function that uses upvalues within that script, and in script B I want to call script A's function

Are you implying I can achieve what I want by declaring outside of class?

[wintry quarry]

What's an "upvalue"?

[summer thorn]

A variable only script A has access to

[wintry quarry]

This is all very vague and you're using nonstandard terminology. Maybe show a code example of what you want?

[rocky canyon]

i was mentioning static classes

[summer thorn]

I want something like javascript's exporting module feature

[polar acorn]

A private variable?

If you want it accessed elsewhere, you'll need to make it public

[fallow socket]

does anyone have any good guides to doing things strictly through code?

[summer thorn]

I just want a function in one script that can be accessed in another

[wintry quarry]

That's just a public function

[polar acorn]

public and reference the object that has it

Because bossHp never changes?

[fallow socket]

i think the biggest thing im lost on, is how do you draw menus?

[wintry quarry]

How should we know? Debug the code. Add better log statements than that which tell you what's actually being printed

[fallow socket]

do you create them as assets first?

or is there a drawing library

Depends on which UI framework you're using. #🧰┃ui-toolkit is much better about code-only UI though

[fallow socket]

this is helpful thanks

[rocky canyon]

https://unity.huh.how/references/serializing-component-references

this is the simplest way ^

[polar acorn]

Are you calling SetBossInfo every time the bossHp changes?

[wintry quarry]

Maybe you're referencing the wrong Image, or looking at the wrong image's inspector

[summer thorn]

Do I just use the "public" keyword to declare my function/dictionary, and make sure I do it outside a class?

[polar acorn]

You can't declare anything outside a class

[rocky canyon]

to reference it outside the script it needs to be public yes

[wintry quarry]

You cannot declare things outside of classes it's not clear where you got that idea from

[polar acorn]

So, after bossHp changes, where do you change hpFill.fillAmount?

[summer thorn]

But how do I achieve what I want?

[wintry quarry]

Make a public variable or function

And call it

[rocky canyon]

and as long as its public and u have a reference to the script instance u can just do
thescriptImReferencing.YourPublicFunction();

[polar acorn]

By referencing the object you want and getting the variable from that

[summer thorn]

How do i declare the function though

[wintry quarry]

Same as any other

But with the word public

[polar acorn]

with public

[summer thorn]

I dont get ittttt

[wintry quarry]

Looks like you're also using DOTween here

[summer thorn]

Someone said I can't declare anything outside class, but if I declare inside class with public keyword won't it confine the var to scope of class?

[wintry quarry]

You might be launching a bunch of overlapping tweens

[wintry quarry]

No

It becomes accessible outside

That's what public means

[polar acorn]

Is there anything else changing hpFill?

[summer thorn]

Oh that was easy

[polar acorn]

I mean, it is, that's why you need a reference to the object that has the variable or function

Where do you assign hpFill?

[summer thorn]

And do folders exist that I can group gameobjects with?

[wintry quarry]

Folders for GameObjects? No.

Just empty GameObjects

Are you confusing GameObjects with classes though?

[summer thorn]

So theres no other way to group multiple gameobjects

[polar acorn]

Depends what you mean by "Group"

Okay, so, is your bossHP ever less than 1?

[wintry quarry]

Are we still talking about code or are we now talking about GameObjects in the scene hierarchy?

[polar acorn]

Yes, the maximum fill amount is 1. 10000 is indeed larger than 1

[summer thorn]

The latter, if my understanding that gameobjects are physical instances in the hierachy and scripts are part of a different hierachy is correct

[polar acorn]

so when you set the fill amount to 10000, it becomes 1

[polar acorn]

Scripts are not part of a hierarchy.

[wintry quarry]

No. Scripts are just code. A class that derives from MonoBehaviour is the code to define a custom Component.

GameObjects are holders for Components

[summer thorn]

But scripts can be rearranged into folders, at least visually

I just wanna know if there's the same thing but for gameobjects

[wintry quarry]

Just the scene hierarchy

[summer thorn]

So the answer is "no"

[wintry quarry]

And using empty objects as "folders"

[rocky canyon]

using UnityEngine;
public class ScriptA : MonoBehaviour
{
    [SerializeField] private ScriptB scriptB; // assign in inspector
    private void Start()
    {
        scriptB.RollCall();
    }
}```
```cs
using UnityEngine;
public class ScriptB : MonoBehaviour
{
    public void RollCall()
    {
        Debug.Log("Here!");
    }
}```
> When Script A's Start() runs, Script B will log : "Here!"
> GameObject w/ ScriptA Attached, References GameObject w/ ScriptB Attached
> Each GameObject has it's *own* instance of `ScriptA` and `ScriptB`

u could therefor assign yet another gameobject w/ ScriptB to the gameobject w/ ScriptA

as it would have its own instance of B.. had u attached it to that gameobject ofc

The Hierarchy only organizes GameObjects

[summer thorn]

If instead of .RollCall it were .SomeDictionary,RollCall, and the .RollCall entry were removed from the dictionary in one instance of the script, but not removed from the other instance, would the change propagate over and end up removing the entry in both instances resulting in neither script being able to call the function?

[rocky canyon]

each instance would have its own dictionary

[polar acorn]

Each instance of ScriptA, specifically

[rocky canyon]

soo i don't think the elements within that dictionary would matter at all to the other collection

[polar acorn]

Hang on I think this is confusing the matter more

[rocky canyon]

yea, lol dictionarys changed the vibe

im too newb to know if you can remove a Function from an instance of a script..

that part confuses me yea

[summer thorn]

Mmmm, in that case how would I store data to be accessed from multiple scripts?

[summer thorn]

I didn't mean removing a function, just removing a key-value pair from a dictionary

[polar acorn]

public class DataHolder : MonoBehaviour {
    public Dictionary<int, String> someDict;
}

You would attach DataHolder to a GameObject. Every DataHolder has a different dictionary.

public class DataManipulator : MonoBehaviour {
  public DataHolder holder;
  
  void Start(){
    holder.someDict[42] = "The Answer";
  }
}

This would go onto any other GameObject (or the same one), and you would drag in a DataHolder. The Start function would then manipulate that object's dictionary by setting the value for the key 42 to "The Answer".

[rocky canyon]

say if an enemy had a list of potential targets
a different enemy would have its own different list
you'd be changing each instance's list differently..

yea.. in that case removing a key-value pair from one instance wouldn't affect the other.. (unless its like a static class)

where theres only one instance.. unless im misunderstanding

[polar acorn]

You could have any number of DataHolders and DataManipulators. The Dictionary belongs to a DataHolder. The DataManipulator changes that one, so if a different DataManipulator referenced the same DataHolder, they'd all be modifying the same dict

[rocky canyon]

its up to u to correctly access which instance whose instance etc

whats ur intention btw?

what does this even pertain to

[summer thorn]

So it seems I'd attach manipulator to holder, then attach holder to any script I want to read the data stored in dictionary from, correct?

[polar acorn]

You'd attach DataHolder and DataManipulator to whichever game objects you want, then you'd tell each DataManipulator which DataHolders you want them to reference

You don't attach scripts to scripts

You attach scripts to GameObjects

[summer thorn]

I want a dict to store data and two functions to read/write from that dict, ensuring multiple scripts can access that dict consistently.

[summer thorn]

Does this achieve the desired effect, or will a modification made to the dict by one script not propagate when a second script reads from the dict?

[polar acorn]

The dict belongs specifically to the DataHolder. If something references the DataHolder and manipulates the dictionary, it would affect that dictionary

If you made a third script:

public class DataReader : MonoBehaviour {
  public DataHolder holder;

  void Start(){
    Debug.Log(holder.someDict[42]);
  }
}

It would print "The Answer" as long as another DataManipulator has already run

[summer thorn]

Someone said earlier that there are multiple instances of a script, a separate instance every time it's attached to a separate gameobject

Is that true?

[polar acorn]

Yes. If you had multiple DataHolders, they would each have their own dictionary

[summer thorn]

So I'd need to pass a script, which interacts with the script containing the dictionary, around my separate gameobjects, that way mutations will propagate across separate instances of scripts

[slender nymph]

if something does not need to be associated with a specific instance, it likely needs to be static

[wintry quarry]

Sounds like you want a singleton

[summer thorn]

What about a concrete example, a script attached to a cube will continuously increment a value within a dictionary, another script attached to a sphere will continuously log that same value. How do I structure my scripts?

[wintry quarry]

(Singleton is just a fancy word for "script of which only one copy exists)

[wintry quarry]

The thing that holds the score would be a singleton

[rocky canyon]

and since only (1) copy exists its easily accessible all thruout the scene

[wintry quarry]

ScoreManager or something

[rocky canyon]

u can only be referencing 1 instance no matter wat.

https://unity.huh.how/references/singletons

[fleet venture]

can i make unity objects nullable?

because unity doesnt rly like null right?

[timber tide]

yes but dont

[fleet venture]

but i need to

[summer thorn]

Oh I see, we got here in the end

[rocky canyon]

lol

[fleet venture]

like logically

[slender nymph]

why

[fleet venture]

or is there like an optional i can use?

[wintry quarry]

They are nullable.

What isn't nullable are serializable pocos

[slender nymph]

technically they already are because they are reference types, but what exactly do you need?

[wintry quarry]

Unity objects can be null

[fleet venture]

a value thats only used if some boolean is set to true otherwise its unused

aka otherwise its null

[rocky canyon]

i feel this in my debugging nightmares

[fleet venture]

and then later i want to check it null

i dont get whats wrong with null T-T

[slender nymph]

this is not an answer
https://xyproblem.info

[wintry quarry]

You can use nullable types they're just not serializable

[fleet venture]

i mean thats pretty clear

[slender nymph]

reference types are already nullable

[wintry quarry]

But yeah explain what you're trying to actually do

[fleet venture]

this is really hard to explain

illt ry

[slender nymph]

no it's not because you aren't actually providing any useful information. reference types can already be null, there is no point in making unity objects "nullable" because they already are and you aren't actually describing what exactly you are trying to achieve

[fleet venture]

void UpdateOutline(bool outline)
{
    if (isTile)
    {
        GameObject tile = Instantiate(gameObject, transform.position, transform.rotation);
        tile.transform.localScale = new Vector3(1.1f, 1.1f, 1.1f);
        SpriteRenderer renderer = tile.GetComponent<SpriteRenderer>();
        renderer.color = color;
        tile.transform.SetParent(transform);
    }
    else
    {
        MaterialPropertyBlock mpb = new();
        spriteRenderer.GetPropertyBlock(mpb);
        mpb.SetFloat("_Outline", outline ? 1f : 0);
        mpb.SetColor("_OutlineColor", color);
        spriteRenderer.SetPropertyBlock(mpb);
    }
}```i have this but i want to make the tile variable into a field, but itll be null if isTile is false

[slender nymph]

so null check it?

[fleet venture]

but its not nullable

im rly confused aobut them already being null

it doesnt have the ?

[slender nymph]

it's a fucking reference type, it's default value is null

[summer thorn]

It looks like we have to write the code which makes the singleton a singleton..

[timber tide]

tile is just a reference. Unless you instantiate, it'll be null

[fleet venture]

since when does C# work liek that

[slender nymph]

since c# 1

[fleet venture]

i thought c# had null safety

i swear this is diff than normal

or im going crazy

[slender nymph]

nullable reference types (which is just a compiler hint and doesn't actually prevent null if not on the variable) only became default in c# 10

[fleet venture]

oh

[slender nymph]

and unity doesn't even support c# 10 yet

[fleet venture]

see thats whats diff probably

normally the IDE would scream at you

thats probably the thing im missing here

[grand snow]

option<> in rust or std::optional ❤️

[rocky canyon]

thats to set up the reference and basically error check for you

[summer thorn]

I don't think that's the singleton I want though, wouldn't it be this

[rocky canyon]

u can create one w/o any of that but its better to have it.. he even has a generic one

[rocky canyon]

thats basically the same thing// but without the error checking in Awake()

[summer thorn]

When would that error arise

[slender nymph]

that's the same thing, but without the stuff that ensures that there is only a single instance

[rocky canyon]

^ stuff happens

[summer thorn]

Hm, what's the purpose of unity api including singleton keyword if it doesn't behave as expected?

[slender nymph]

it doesn't include the singleton keyword

[rich adder]

singleton is a pattern

not a keyword

[slender nymph]

there is no Singleton keyword

[grand snow]

singleton is a vibe

[rocky canyon]

lol

[grand snow]

FUCK

[rich adder]

relate

[grand snow]

i do not 😎

[summer thorn]

is there a well documented api i can refer to that's better than unity's official one?

[slender nymph]

huh?

[rocky canyon]

i think unity would know its api better than anyone

[slender nymph]

are you asking if there is a package that includes a singleton type? because that is almost entirely unnecessary where you can just declare it yourself

[grand snow]

a static property + setting/checking in Awake() should be sufficient

[wanton epoch]

Im so confused, I continously get this error yet im sure that ive solved the issue:

Error: "Assets\Scripts\PlayerAttack.cs(36,62): error CS1061: 'Enemy' does not contain a definition for 'TakeDamage' and no accessible extension method 'TakeDamage' accepting a first argument of type 'Enemy' could be found (are you missing a using directive or an assembly reference?)"

Scripts (first is attack, second is enemy):
https://paste.mod.gg/lrzhxzcocdho/0

[summer thorn]

I'm asking if there are clearly defined definitions for public, private, static, and so on. Maybe that's c# and not specific to unity, but the apis I've found assume prior knowledge

[grand snow]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/

[summer thorn]

I've just migrated to unity and the official api page is illegible

[grand snow]

Unity docs is for the unity specific api, its not going to cover the spec for the C# language

[slender nymph]

you should perhaps start by learning the basics of c#, there are beginner courses pinned in this channel

[rich adder]

did you save all your scripts changes?

[wanton epoch]

yea

[rich adder]

the line doesnt even match

enemy.TakeDamage is on 35 here

[wanton epoch]

ikr, but for some reason, my unity wont update

[summer thorn]

Ohh I see thanks

[slender nymph]

did you do something silly like disable the automatic asset refresh?

[wanton epoch]

idek what that is or how to do that

[rich adder]

yeah would check there

[wanton epoch]

welp just refreshed manually and yea that fixed the issue. Ong idek how i did that

didnt even know that was a thing

how do i renable it?

[rich adder]

somewhere in preferences i think

they changed it so forgot new location

[wanton epoch]

nope its enabled

[slender nymph]

it's in asset pipeline settings or something like that

[wanton epoch]

so idk y it didnt refresh

[polar acorn]

Honestly Unity's API page is among the best out there, other than having some odd choices for the order they put the overloads in

[wanton epoch]

genuinely confused af

[rich adder]

sometime it would happen to me to when adding new script through Add Component on a prefab
had to manually refresh it , it was fixed in later patches

[slender nymph]

then either you didn't actually save or you've got something else that prevented it from recompiling like some hot reload asset

[wanton epoch]

welp either way its fixed and hope it doesnt happen again

[grand snow]

are you on linux by any chance?

[wanton epoch]

nope windows

[grand snow]

hm no idea then 😆

[summer thorn]

Btw, is unity supposed to freeze and reload many things whenever I switch back to it from VSCode after making a single-character change?

[wanton epoch]

yes

just accept it

[slender nymph]

it is supposed to recompile the code and reload the domain, yes

[summer thorn]

Is there a way to manually compile or even do so at runtime?

[rich adder]

thats one thing holding back unity until core clr is out

[rich adder]

you can switch to manual compile

[summer thorn]

Yes please where

[rich adder]

#💻┃code-beginner message

Edit -> Preferences

i think after you press ctrl + r ?

[slender nymph]

note: that affects all assets, not just compiling. so any time you want to add a new asset or update an existing one you need to refresh

[summer thorn]

That turns me off

You mean this?

[rocky canyon]

disable directory monitoring should be enuff

[summer thorn]

All that'll do is prevent code recompiling until runtime right?

[grand snow]

i dont really have this issue i edit what i need, save and go back and wait 10s~

[summer thorn]

If that's the case is there a button to manually recompile before runtime

[rocky canyon]

when u update a script afterwards u Ctrl+R to refresh the project

[summer thorn]

To manually recompile?

[rocky canyon]

then thats when the new changes become compiled

[summer thorn]

Oh alr

[rocky canyon]

mmhmm

[slender nymph]

if by "runtime" you mean "until i either refresh or build the project because entering play mode does not trigger a compile" then yes

[rocky canyon]

you'll have to press it in unity ofc.. wont work in the ide 😄

[rich adder]

do you really need to alt + tab after every little change?

[polar acorn]

I'm wondering what the use case is for changing something and then not wanting to see that change when you go back into Unity

[rocky canyon]

its not so bad if ur navigating around ur codebase in the ide

but if ur a dweeb like me and want to make multiple changes at once.. it requires going back thru the project directory to open that 2nd script.. (in those cases its useful not to have it compile inbetween)

[summer thorn]

You really don't? I tabbed back into unity to check the name of a gameobject a couple times, wasted 30 seconds waiting for the loading bar

[rocky canyon]

but thats skilll issue.. i gotta get better at navigating around via the IDE

[slender nymph]

use the solution explorer rather than the project window in unity to navigate through your project's cs files

[polar acorn]

You can edit in the IDE while it's compiling

[rocky canyon]

i 100 agree box

just gotta make habit of it

[grand snow]

Type search is easy to do in VS and VS code! use that and avoid going to unity when not required ✨

[polar acorn]

If you tab back you can view something and then go back into the IDE while it's compiling

[summer thorn]

Can't view no nothing if a loading bar is in my way

Why they don't just recompile in the background and not allow you to run or view scripts until compilation is finished is confusing

[rocky canyon]

imo that'd be cool to have it recompile in the background after i save a script in the ide

[grand snow]

old ass engine 😆

[rocky canyon]

but knowing me.. i'd find something wrong about the way that works

or something that hinders my workflow in some other way lol

[slender nymph]

rider triggers the asset refresh (and thus recompile) without needing to tab back into unity

[rocky canyon]

lol.. flex

[grand snow]

vs can do this too btw

no idea about vs code

[coral crater]

I'm trying to figure out a maths formula for calculating how far between two times the current time is. the NPCs in my game have "schedules" (like harvest moon/stardew), so I need to figure out a formula that tells me how much through the current schedule we are in a 0-100% system

eg. how can I write a formula for saying that the number 350 is 50% between the numbers 100 and 600

[rich adder]

lerp or inverse lerp mayb?

[polar acorn]

InverseLerp

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Mathf.InverseLerp.html

[timber tide]

Normalizing formula is something like (current / max) * 100

oh but you want to start at 100 uh

[polar acorn]

If it starts at 0

[coral crater]

this worked perfectly. thanks so much! (also @rich adder)

[timber tide]

I think it would be:
((current - min) / (max - min)) * 100 then

[coral crater]

also works incredibly. cheers

[swift crag]

inverse-lerp is great

i use it all the time, even for things that seem trivial

like Mathf.InverseLerp(0, limit, loopVariable);

[wanton canyon]

I am having an issue trying to change an image, and I think I am overlooking something simple. I have a gameobject in the center that I want to change the image when I click a button on the left. on the button, I have the script. During initialization: [SerializeField] private Sprite girlIMG; //set the img I want to change to
[SerializeField] private GameObject ClickerIMG; //set the game object in the middle
private Sprite clickerIMG;

in start: clickerIMG = ClickerIMG.GetComponent<Image>().sprite;

on click: clickerIMG = girlIMG;

I also have animations on the image in the center, so Im not sure if that is messing with anything

[polar acorn]

I'm a big fan of Lerp(a, b, InverseLerp(c, d, x))

[swift crag]

aka, a remap!

[polar acorn]

Yep

A one-line change-of-basis

[orchid flare]

asking here because #🤖┃ai-navigation is dead. Does anyone know where I could get regularly-available expertise or just resources for ML-Agents? Or would I need to hire them

[modest dust]

clickerIMG is of type Image and you're trying to set it to girlIMG which is of type Sprite.
You should instead do clickerIMG.sprite = girlIMG

[swift crag]

#🤖┃ai-navigation is for navmeshes and traditional game AI

#1202574086115557446 will be more on-topic, at least

[modest dust]

Also why serialize the GameObject when you can serialize the Image component directly, getting rid of the GetComponent call

And yes, a running animation on the image will immediately override whatever sprite change you make.

Either disable it or make a new non-looping animation state for that sprite and trigger it

[wanton canyon]

yeah I am kind of confused how best to go about this. I want one animation to be the same for each sprite, but the other one to be different

[coral cape]

I have a prefab set up with this in my script, then I have a pointer down even trigger to which I dragged itself into the object space on the bottom left, and I referenced the explosiveClicked script which Ill paste below:

"using UnityEngine;

public class popObject : MonoBehaviour
{
public int testInt = 0;
public void explosiveClicked()
{
Destroy(this.gameObject);
testInt = 1;
}
} "

but they dont register any clicks when these prefabs are spawned throughout the world. I do have these prefabs being randomly instantiated in the default layer in the world while I have a convas overlayed ontop of them

[modest dust]

Describe your issue in more detail then

Maybe some screenshots for more context, etc

[wanton canyon]

clickerIMG is initialized as a sprite, doing clickerIMG.sprite = girlIMG gives error "sprite does not contain definition for "sprit""

[polar acorn]

Well, it's true. Sprite does not contain a definition for .sprite

[modest dust]

Oh, I didn't notice the type, only the GetComponent call.

[polar acorn]

You want to change which sprite your actual renderer is using, which would be either a SpriteRenderer for a world-space object or Image for UI

[modest dust]

Dang, alright, I didn't notice some more things

You're doing clickerIMG = ClickerIMG.GetComponent<Image>().sprite which only takes the reference to the sprite asset currently in use by the Image component attached to the ClickerIMG GameObject

You want to modify the sprite in use via imageComponentRef.sprite = yourSprite

So it would be ClickerIMG.GetComponent<Image>().sprite = girlIMG

Best if you reference Image instead of GameObject in ClickerIMG to not get the component each time

[polar acorn]

But also ClickerIMG should just be of type Image so you don't have to GetComponent it a bunch

[wanton canyon]

Alright I must still not be understanding something. So far I have changed it:
(Initialization)
[SerializeField] private Sprite girlIMG;
[SerializeField] private Image ClickerIMG;
(OnClick)
ClickerIMG.sprite = girlIMG;

and it's still not working

[swift crag]

and what does "not working" mean?

compile error? runtime error? no error, but no change?

[wanton canyon]

it's not chaning ClickerIMG

no errors as of now

[modest dust]

There's still the animation part you mentioned.

[swift crag]

You said that you have an animator that controls the image.

The animator will clobber whatever you do every single frame.

[wanton canyon]

oh yeah maybe I should disable that one sec

^same result

[polar acorn]

What calls OnClick

[wanton canyon]

the button, the script is attached to the button and the OnClick is on the button as well

[swift crag]

Verify that the function is actually running.

You can do so with Debug.Log. It's a method that writes a message to the console.

[wanton canyon]

yes

[polar acorn]

Just to make sure, the sprite you dragged in for girlIMG is different than the one that ClickerIMG already starts with, right?

[wanton canyon]

yes

[polar acorn]

And ClickerIMG is an object in the scene, not a prefab?

[wanton canyon]

yes, not a prefab

[polar acorn]

Can you show the full !code for your OnClick method

But do make sure that you click the button after you disable the Animator

[wild island]

I'm confused about Awake() and script reloading
The docs say to "use Awake to initialize variables" but when scripts are recompied during run mode the objects are seemingly recreated, and then Awake is not called, how does this make sense?

[polar acorn]

Disable the entire animator for now

[polar acorn]

Awake is called when you hit play

[wanton canyon]

IT WAS THIS AKFNBJKSANBHFJKSANBJGABS JK

i knew it was s mmthing stupid thank you

[polar acorn]

Yes, that's why we said to disable it. If it's changing the sprite, it's going to always be doing that

[wanton canyon]

alright alright, now I gotta figure out how to do the animations I want, but I'll go try to figure that out on my own

[wild island]

I'm confused about Awake() and script

[lean pelican]

How do I elegantly generate a list of random numbers so that any number is at least a certain value apart from every other number.?
As in for every combination of elements x, y in myList, Difference(x,y) > myThreshold.

My attempt was to randomly generate a number, compare it against every existing number in my Array, and if it's too close to an existing number, reroll it, then start the comparison from the top, and if it passes every comparison, add it to the array.

However in code it ended up a right mess of a nested for, while and foreach loop with an intentional break; in there. ...And it doesn't even work because the numbers can just randomly be too close to another, and even with logging every single comparison, I can't figure out the pattern to that.
So I'm wondering if there's a more sensible method/implementation of going about it.

[swift crag]

break only exits the closest while/for/foreach loop

Consider a "success" variable that you set to false if you find a conflict

[lean pelican]

That's what I tried.

[swift crag]

I presume you have three loops here:

• For loop -- Generate 100 numbers
  • While loop -- Try forever until we get a number
    • Foreach loop -- check if any conflicts exist

share your code.

[modest dust]

Why not just a single loop

Provide some more constraints besides the threshold

[swift crag]

you could fold the first two together

while we have less than 100 numbers...

try to generate a new number

[modest dust]

Is there any range the numbers must be in or completely random?

A set amount of numbers or also random?

[lean pelican]

It's supposed to be coordinates for objects spread around the screen without getting too close too each other, so for my screen the range is like +/- 8. The amount of numbers (strictly Vector2, but those are just pairs of numbers) is a parameter.

https://hastebin.com/share/venoyohiro.csharp

https://hastebin.com/share/ugajuzotid.csharp

[lean pelican]

Actually it should be this one. I did figure out I had to break out of two loops at once.

[modest dust]

Alright, so it's not just single numbers but rather coordinates in 2D space.

[modest dust]

One way is to just transform the 2D space into a grid where each node is threshold away from each other, put the node coordinates into a list and randomly choose clouds amount of them.

List<Vector2> remainingNodes = // All nodes
List<Vector2> chosenNodes = new(); // Empty list
while (clouds-- > 0) {
  int random = Random.Range(0, remainingNodes.Length);
  chosenNodes.Add(remainingNodes[random]);
  remainingNodes.RemoveAt(random);
}```

Then, if you don't want them to be snapped to the grid, you can offset them up to `threshold / 2` distance towards some neighboring nodes which were not chosen.

[lean pelican]

That's pretty clever. ...How do transform the space, though?

For reference I'm in a main menu scene that otherwise only has UI objects, and the field of view is like 20 by 16 or so Unity units.

[modest dust]

You've got a certain area where you want to spawn the objects, bottom right corner being at (-8f, -5f), top right being at (8f, 5f). At least that's how it is in the code.

Your total width is 16f, height 10f

[lean pelican]

The area is a bit bigger, but that's about where the centre of the sprites can be without them going too far offscreen.

[modest dust]

(int)(axis_size / threshold) would be the nodes count on a certain axis

axis_size - axis_nodes * threshold would be the remaining space on that axis

offset the grid by remaining_space / 2 to center it

Then simply iterate... axis_start_pos + axis_offset + (node_num_starting_from_0 + 0.5f) * threshold in a double loop for each axis to get the center position of each node.. if my math is correct here of course.

[lean pelican]

'nodes' are also Vector2, right?

[modest dust]

Could be (int, int) coordinates which are later translated to world position via the thing I wrote above

Which would be also easier to use when searching for neighbors to offset the chosen node

ie. if (remainingNodes.Contains((x - 1, y)) // Space to the left is empty, can offset in that direction

[lean pelican]

Interesting. This is really helpful, thanks a ton^^. I understand the idea, so I can definitely do something with this ...tomorrow; it's like 2AM for me.

[modest dust]

Good luck with it

[lean pelican]

Thanks^^

Hi all. I test my game in Unity Remove and All Work, but i build and test my phone, gyroscope and Input.Touch() don't work, why? Unity 6.0.31f1

[wintry quarry]

Get.Touch()
What's that? 🤔

Anyway - Unity Remote is not a replacement for actually making a build. THinks like gryo and touch support will be limited

You should test with a real mobile development build.

[white glade]

i test my phone, not work

[hearty glade]

Hi, if I didn't reference a prefab, is there a way to get them from their parent and delete them all?

[wintry quarry]

Can you be more specific here?
You are using "them" "their" and "them" and I have no idea what these pronouns are referring to.

[hearty glade]

like this. but it doesn't seem to delete the prefabs.

[wintry quarry]

wdym by "ddelete the prefabs"

can you be specific about what you mean by the prefabs here?

Show me the objects we're talking about?

Which objects are you expected to be deleted

Prefabs live in the project/assets folder

you never want to delete them

[hearty glade]

I mean instantiated prefabs

[wintry quarry]

Destroy will destroy whatever you call it on

if specific objectgs are not being destroyed then you are calling Destroy on the wrong objects

or your code is not actually running

Have you taken any debugging steps here?

also .gameObject is never going to return null

so that null check is unecessary

if the object had already been destroyed, you would have gotten a MissingReferenceException when you called .gameObject

[hearty glade]

Current hand object is referrenced to the currentHand variable and I try to delete the clones by Destroy(currentHand.GetChild(i).gameObject); but it doesn't seem to work.

The clones are still there

[wintry quarry]

Again, what debugging steps have you taken here?

You should be adding Debug.Log to your code and seeing which parts run, and what the childcount is, etc

This part of the code may simply not be running at all.

[hearty glade]

Thank you so much! turns out I was callign a different method 🤦‍♂️

[wintry quarry]

yep - that's why we debug

[wet bay]

hiya, trying to make a very basic Snake to get a feel for some of the available stuff, and it seems like the LineRenderer component is just very janky? I can't seem to get it to turn sharply without having the line be distorted, and most of what I've found online about this boils down to either no answer, 'line renderer is bad', or 'yeah, it's annoying, right?'
Is there a way to fix this or some alternate method I should be taking to render this?
(For a bit more context, I am simply adding a new point to the line renderer every second based on my current direction, so basically there's one point at the center of each grid tile)

[drifting cosmos]

dont use line renderer

or spawn a new line every time

[wet bay]

how helpful

[drifting cosmos]

yes

[wintry quarry]

Is this a screenshot of your linerenderer?

[wet bay]

yeah

[wintry quarry]

That looks hand drawn...

That's not normal for linerenderer

[wet bay]

yeah I wish lmao

[wintry quarry]

You're doing something weird

How big is this grid

[wet bay]

I did end up ""fixing"" it, I had the width non-uniform

but it doesn't have the effect I wanted of having it get thinner

[wet bay]

1x1 per tile

[wintry quarry]

Wdym by getting thinner

[wet bay]

this fixed it

this was it getting thinner

[faint osprey]

im making a behvaiour tree and in one of my check nodes i want to check for when the health pick up spawns now at the moment i have my health pickups fire an Action when they spawn so should i make my check listen to that and then return successful or shod i do it somewhere else

Hey ppl unity newbie here im having trouble setting up VSCode with unity correctly (windows 11 WSL2), here are my main issues:

1. intellisense doesnt seem to work when i open my unity project using visual studio code on wsl2 (i.e. code path-to-unity-project)

Cannot find .NET SDK installation from PATH environment. C# DevKit extension would not work without a proper installation of the .NET SDK accessible through PATH environment. Rebooting might be necessary in some cases. Check the PATH environment logged in the C# DevKit logging window. In some cases, it could be affected how VS code was started.

2. im not sure how to set the unity preferences to open visual studio code in wsl2 instead of windows

Here's what ive done:

• I installed .NET on WSL2 using the install script (in WSL2, dotnet --version gives 8.0.405):

wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh
chmod +x ./dotnet-install.sh
./dotnet-install.sh --version latest

• added .NET on my ~/.bashrc (and closed and opened the WSL terminal)

export DOTNET_ROOT=$HOME/.dotnet
export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools

• On my WSL VSCode ive installed the following extensions: C# Dev Kit, Unity
• My Unity Hub + Unity Editor install was done on windows
• Unity > Edit > Preferences > External Script Editor > Visual Studio Code [1.97.0] (windows install)

does anyone know the right way to do this? do i also have to install .NET SDK for windows even though ill mainly be using WSL? thanks

[grand snow]

well i should point out that you installing the .net sdk for windows will do nothing for WSL, install what you need in WSL too.
I should also question why you are trying to mix wsl + windows unity editor? what are you trying to do even

[finite pendant]

actually thats a good point tbh, do i need to use dotnet at all on the terminal for unity?

[grand snow]

the unity editor on windows doesnt need .net at all. You only need to install the sdk for vs code and/or visual studio to work correctly.

unity uses its own mono compiler

[finite pendant]

ooo okok

im making a behaviour tree and my HealthExists check wont bound to the events because its a standard c# class and not a mono behaviour so how would i make it listen to events

[slender nymph]

only UnityEngine.Objects have Awake called. if this does not derive from a class that has Awake called on it, and is just a plain c# class then either subscribe to the events in its constructor or give it some method you call immediately after instantiating it and subscribe in that method. you're going to want to unsubscribe somewhere too unless you just want these objects hanging around in memory after you are done with them

[blissful yew]

I want a unique ID for each of these scriptableobjects (which are read-only information about levels). I'd like to have it generate one time on creation and have it never change thereafter, same ID for all players. I tried to use Guids but their behaviour is bizarre... they keep regenerating for no discernable reason... should I just generate my own random ID string OnValidate and plug that in and not bother about Guids?

[slender nymph]

they keep regenerating for no discernable reason...
likely your code is wrong somehow. show what you tried

[blissful yew]

they'll be used for saving/loading basically. Referringg to a dictionary of IDs

[slender nymph]

unity does not serialize properties

i'm assuming you're using odin to display the property in the inspector but that does not mean its backing field is being serialized by unity

[blissful yew]

What does that mean it doesn't serialize properties? And yes without ShowInInspector you can't see the ID even in debug for some reason. And without ReadOnly it lets your press the 'New GUID' button

[slender nymph]

i mean the property is not serialized which means its value is not being saved.

[blissful yew]

My other properties don't reset like that though

[slender nymph]

if you open up the asset file with a text editor you'll see that the yaml does not include anything regarding that guid because it isn't being serialized

[blissful yew]

Yes so I see now the 'serializable' note at the end... why is only Guid not serialized...? These are all properties

[slender nymph]

notice how literally all of the other properties have a SerializeField attribute targeting their backing field

[blissful yew]

omfg did I really...

[slender nymph]

although fwiw i don't think jsonutility can serialize GUID anyway so you'd probably want to serialize it as a string or uint or whatever

[blissful yew]

No but it doesn't like that. Won't serialize it.

[blissful yew]

Oh okay, I'll just do my own little random string generator

[slender nymph]

or just ToString the guid?

[blissful yew]

Yup, works fine. Thanks. So what is even the point of Guid then? Besides NewGuid().ToString() being a good way to make random strings

[slender nymph]

just because unity doesn't serialize the GUID type doesn't mean there is no/little point to it. it's still useful as a unique identifier

[blissful yew]

Is there a reason it doesn't/can't serialize that?

[slender nymph]

jsonutility is very limited and that's what unity uses to serialize fields

[blissful yew]

ah, yeah. I finally had to give up on jsonutility and just use newtonsoft

Which is really not any harder. Not even sure why jsonutility is a thing

[visual linden]

JsonUtility is a lot smaller - Useful if size is an issue

[blissful yew]

Thanks again. I swear I've struggled with Guid like 3 separate times in the past year or two... now I finally know to just sidestep it haha

Also, do you guys use OdinInspector a lot? It's good but I heard some people saying it makes porting harder, or something like that. Some kind of scalability issue

(classic small game dev thinking about scalability for no reason)

[slender nymph]

if you're using Odin you can probably use its SeralizedScriptableObject to serialize things like GUID properly. i haven't used odin in ages though so i'm not actually 100% certain if it supports GUID (though if it can show it in the inspector then it probably does)

[blissful yew]

Any advantage to doing so over this simpler string ID method?

[slender nymph]

no workarounds needed 🤷‍♂️

[blissful yew]

true but then it's Odin reliant. Any reason you haven't used Odin? Don't like it or just haven't needed?

[slender nymph]

last time i used it i had performance issues in the editor that were related to it so i stopped using it then i just haven't had a need for it since

[visual linden]

Only drawback to Odin is that you're creating a dependency in all your code, which can be a bit of a shame if you want to carry systems over to other non-Odin projects.

[blissful yew]

Hmm, I'm only using it on this kind of behemoth read only class that basically encodes all the information about a level. It's rather unwieldy without Odin.

So I guess just don't use it on parts of the code you expect to want to reuse in the future for other projects

[zinc lintel]

Hey, is there an easy way to sort a list of integers ?

[slender nymph]

is List.Sort not sufficient?

[zinc lintel]

I'm not sure how to use it

[slender nymph]

have you tried googling it?

[zinc lintel]

Yes but everyone seems to be using loops, and going through the whole list, i thougt there would be a simpler way like for Array.Sort

[slender nymph]

i mean googling the list.sort method

but also c# sort list the first result is the List.Sort method

i thougt there would be a simpler way like for Array.Sort
yes, it is List.Sort as i've pointed out, you're just using it incorrectly because you didn't bother looking at its documentation

[zinc lintel]

Okay i might be stupid, i thought i tried that as the first thing but i might have just forgotten to do it 😭

Thank you for the help, i was somehow sure that i had already tried that but i guess i didn't

[void dawn]

Ok so I tried making a script that the gun in my fps game always shoots in the center of what the camera is Facing , the problem ? I can't put the players camera in because it's in a scene not in the assets , so all the guns just shoot what in the direction of the main camera in the scene , so all the bullets always follow the same direction, what would you suggest to fix this error

[eternal needle]

the gun shouldnt care about the camera in the first place. it just needs a direction to fire at, some other code should provide this value. if you're trying to make npcs shoot as well, you could probably base it off the forward vector of the transform or the direction to the target

[void dawn]

That's a good idea

[void dawn]

So I should make some other way to make them fire at the center of the screen in the direction of the cross hair right ?

[eternal needle]

the gun script should have no concept of what the center of a screen is even. it just needs the direction to go. id say whatever script is specific to your player (like input) can provide the direction and hold a reference to the camera

[void dawn]

Got it so I should just make something like a line so the bullet can follow ?

[oblique iris]

hi. im making a ball rolling game (or at least i have been extremely on and off about it for the past 2 years). it serves as an exercise for me to actually learn c#.

the ball rolls around with rigidbody. i am trying to make a focus mechanic where holding down the spacebar will override those physics and make it slide around at a set speed (hard start and stop, no rolling) for more precise movement. after some research i suppose i should do destroy rigidbody and add it back when spacebar is released.

there is another script that is a double jump and it depends on the rigidbody. because of this, i cant destroy the rigidbody. so i thought "okay ill just disable that script while spacebar is pressed" but im unsure if that is actually a thing. regardless, i tried. im getting errors so i decided to ask what the problem could possibly be

admittedly i need to look at beginner tutorials for the 99th time because the time that passes in between attempts is too great to remember some things. im sure im missing something pretty basic here, but maybe this will point me in the right direction of what to research first

[wintry quarry]

don't destroy it - make it kinematic.

anyway you can't just say "I'm getting errors" and expect us to be able to help you

you would have to say what errors you are getting.

[oblique iris]

i researched this too and i was unsure if that was the way to go, i guess it was

[oblique iris]

yes

well my bad lol the only error is "cant destroy because double jump depends" like i was saying

[wintry quarry]

no you didn't say anything about that

[oblique iris]

did i not?

[wintry quarry]

show the full error message, though it sounds like it's pretty straightforward and self explanatory

You said:
"there is another script that is a double jump and it depends on the rigidbody. because of this, i cant destroy the rigidbody."
Which is vague

It's important to share the actual full error message

But - that also sounds self explanatory - you're destroying something that another script is depending on

[oblique iris]

its all null and void now because i was going for the wrong thing, but this is quite literally it

so i should ask for future reference, say i actually "need" to destroy it for whatever reason. would disabling the other script work or would it not because it still "exists"?

[wintry quarry]

That is popping up because your other script likely has:
[RequireComponent(typeof(Rigidbody))] on it

[oblique iris]

it does. its not my code, followed a tutorial and paid the price

[sharp sigil]

i got my base game and i wanna make it a multiplayer game now but i cant find any packages to do it with i tried netcode but that i cant make it work and im looking for another one anybody have any recommendations?

[wintry quarry]

wdym by "it's a sprite"?

sprites are not things in the game world

It owuld either be a SpriteRenderer or a UI Image

(also this is not a code question at all, wrong channel)

[honest iron]

oh sry

my bad i'll change it to the right channel

sry which channel my question belong to?

[wintry quarry]

idk

is it #📲┃ui-ux or #💻┃unity-talk ?

[honest iron]

is it considred to be graphic or ui

[wintry quarry]

IDK you tell me

is it suppsoed to be UI?

[honest iron]

i'll try uiux

[burnt vapor]

The point of GUIDs is having unique ids without having to manage a state like with incremental ids. It's nearly impossible for a Guid to generate overlapping ids

Still possible, but unlikely.

[wintry quarry]

The error is in PlayerBlock.cs on line 37

[wanton epoch]

i am blind and cant read

thank you very much

[wintry quarry]

And it's because void UpdateStaminaUI() in the PlayerMovement script is private. You need to make it public @wanton epoch

[grand snow]

Don't know if you realised but your if statement is missing {} so it only applies to the first statement after it

[wanton epoch]

thank you a lot kind stranger

[wintry quarry]

ALthough I think it's probably an antipattern to be calling UpdateStaminaUI directly from another script like that.

You should probably instead make a function or property to modify the stamina that also automatically updates the stamina UI

otherwise you can forget to do both

[cosmic dagger]

It is best to manually put public, private, or protected for each of your class members: variables, properties, events, and methods. This increases readability as it allows you to see what is acessible from a glance (and at all times) . . .

[oblique iris]

i did not. thank you. even having correct bracket placement is iffy for me right now

[cosmic dagger]

Every open brace must have a closing brace; that's it . . .

[grand snow]

Your visual studio doesn't seem to be setup fully either but yea it's something to be aware of!

[oblique iris]

i understand that. sometimes i just... miss that. my eyes are still getting used to looking at this kind of stuff

[oblique iris]

thank you. is there a place to read/see where i can fully set it up?

[unborn bronze]

me and a friend just started a project now we want to sync using git/github it works for the files but not for the things in the hieracrhy? so the files are shared but not the position of a square for example anyone know how to fix?

[rich adder]

what things in the heirarchy ?

did you save the actual scene changes and push?

hierarchy is just scene in a YAML file

[unborn bronze]

but where is the yaml file located in the folder structure

[rich adder]

where did you put it?
also in unity it doesnt have .yaml but .asset

[unborn bronze]

nowhere? it just a blank project with a 2d floor in it

[rich adder]

wdym nowhere? you certainly have a scene open no?

[unborn bronze]

yes the default one

the samplescene

[rich adder]

so then you have the scene in the default folder

if it has * you have unsaved changes

git only listenes for file changes when its saved

[tulip stag]

Why use this structure instead of List<myEnum>?

        [Flags]
        public enum SourceTags
        {
            None = 0,
            Official = 1 << 0,        // 00001
            Partnered = 1 << 1,       // 00010
            Homebrew = 1 << 2,        // 00100
            UnearthedArcana = 1 << 3, // 01000
            SRD = 1 << 4,             // 10000
            ThirdParty = 1 << 5,      // 100000
        }```

[polar acorn]

The scene file

[rich adder]

perhaps because enums are more efficient than reference type allocation

you can store multiple values in a single integer

[tulip stag]

I see.
So if I ever need to make a list of items in an enum it's best practice to do it like this, then?

[rich adder]

not always, it really depends on the usecase

List has its benefits too

[unborn bronze]

ah we got it but the scene file is just 1 file right, so we can never work on the same scene? because if he places the character somewhere else and me place the floor somewhere else for example it just 1 file so either a merge conflict or 1 change does not work right?

[rich adder]

correct

[unborn bronze]

so how would we do it then?

[rich adder]

you can lookup the different solutions people do.
usually working on prefabs then join them together
or
seperate scenes as pieces too and also join them

i'd say scene conflicts are the number one issue in unity and vc

[unborn bronze]

that kinda ruins it

[red igloo]

When my player collides with something the player dies and I have a particle system and I want it so when the player gets destroyed this particle system should play. How can I do it?

[polar acorn]

Spawn an object that plays the particles, and removes itself upon completion

[red igloo]

I will try this thanks

[rich adder]

people misunderstand git for live collaboration and it isn't for that

[unborn bronze]

so what is best practise for working together on a game? like how do bigger game companies do it

[rich adder]

bigger companies have people working on different things

[polar acorn]

By separating scenes into either prefabs or multiple scenes, rather than editing the same one

[rich adder]

there is a GDC Talk about this for Firewatch and how they made it a "big map" just by slicing it into different scenes

scenes can be additively loaded so the experience can be seamless

[unborn bronze]

so you should have 1 main scene and then for each contributor a differen scene so they can work on there part and then when you finish your parth you place it in the main?

[rich adder]

https://youtu.be/WMN710Ttg2A?t=394

this explains One way to do this

merge talks begins t 7:50

[unborn bronze]

yes so bassicly this but instead of for each contributor every "part" of your game has a different scene

[rich adder]

thats the idea of multi scene yes

[red igloo]

Instead of doing it the way you said I made the particle system a prefab and assigned it in the inspector. Did i do it correctly?

[polar acorn]

So instead of spawning an object that plays the particles, you spawned an object that plays the particles?

[ivory bobcat]

I think you just did it the way he said to

[red igloo]

I read what he said wrong, Just forget what I said

[rich adder]

did the "AI" generate correctly **

[red igloo]

wdym lol I didn't use ai I'm stopping myself from watching any tutorials or "AI" I just google or go on unity documentation.

[ivory bobcat]

I'm unable to differentiate but those comment lines are pretty strange (unnecessary as it's implied through code).

But maybe experience or different practices are at play

[rich adder]

its just strange because , well you wrote it.. you would know what those methods do no?

[red igloo]

Im still learning XD

[rich adder]

its fine lol just make sure you're actually learning and not copying n paste

[swift crag]

A "flags" enum makes sense when you have a small number of enum values and you care a lot about storing them efficiently.

Notably, you get to use a fixed amount of space (one integer's worth) no matter how many enums are enabled.

However, this limits how many enum values you can represent -- you only get 32 of them. A non-flags enum can have a ridiculous number of values.

[tulip stag]

oh ok ok I'll keep this in mind too!

[dusty geode]

It's not just about storing them efficiently, they also allow the ability for more than one value to be represented at once.

[swift crag]

those go together

it's efficient because you can represent more than one enum value at once

rather than needing a list of enum values

[cosmic dagger]

the efficiency is storing (representing) more than one value . . .

[raw jacinth]

I don't understand

i am a begginer and i work on visul studio

[slender nymph]

you're more likely to get help if you post the error message in english. but i'd bet you need to install the .net sdk or something

[rich adder]

me neither, i don't speak whatever that is

[cosmic dagger]

I don't understand either. What does it say?

[void dawn]

what are some things i should know before i start making enemy ai for my fps game in unity ?

[dusty geode]

Yeah idk what my brain was thinking lol, I guess it's already fried today

[rich adder]

start simple

[raw jacinth]

One or more errors were encountered while creating the project Bases.

It is possible that the generated project content is incomplete.

The specified SDK Microsoft.NET.Sdk could not be found.
C:\Users\Utilisateur\Desktop\visual studio\dyma tuto C#\Cours\Bases\Bases.csproj

[tall sparrow]

you neet to download a .net sdk

[raw jacinth]

it is all?

[rich adder]

maybe. Could also be a corrupt install

visual studio generally installs everything for you

make sure you follow the proper steps !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
• :question: Other/None

[tall sparrow]

same thing happened to me when i got visual studio

i had to manually get the .net sdk

[rich adder]

yeah idk ig..usually its VSC that gives problems

[rich adder]

so you can try install .net sdk, you restart pc just incase also

but still configure according to steps above after

[verbal dome]

Tbh most of the issues I have seen here in the last year were from VS not VSC

[rich adder]

yeah i started having issues with VS the last 3 months of updates, went full VSC

unity plugin for vsc is getting better with each update

[tall sparrow]

im doing c# as my main programming language in college and have decided to make games to practise, could anyone suggest me anything to make that would vastly improve my comfort with the language

[rich adder]

repetition

[cosmic dagger]

It doesn't matter what you make. What matters is what you design or create. Keep doing project after project as you learn new concepts and architecture patters . . .

[tall sparrow]

alright thanks

[raw jacinth]

i restart my pc and install .net sdk

and i have again the same problem

[rich adder]

ok then its probably corrupt?

can you show what the unity external tools window looks like

[slender nymph]

just to confirm you installed the .net sdk then restarted, and not the other way around, right?

[raw jacinth]

yes

[raw jacinth]

i just use visual studio for learn C# beacause i see in tuto that i need C# for Unity

[rich adder]

yes you need c# for unity. You can use any IDE (code editor) you want.
The top dogs are VS, VSC & Rider

[raw jacinth]

for learn C# i use dyma

[rich adder]

dotnet --list-sdks

[raw jacinth]

and the teacher use visual studio

[rich adder]

why's that

[raw jacinth]

so i do same

[raw jacinth]

because it is in french

and i am bad in english

[rich adder]

I mean... you can set any IDE in french

[raw jacinth]

no tuto in french

[rich adder]

its just easier to set your IDE in english to get help on errors + issues

plus you learn the common used words

if you're only learning you can use Rider for free btw

since thats non-commercial

[rich adder]

you copied my typo

congrats

sdks not skds 😛

[red igloo]

Hey so im making a simple ball game where you can move around with wasd and I don't really like how when you move around and try to move the opposite direction its very slow and I want it to be instant.

https://paste.ofcode.org/RAyQpX3V6y2PrFHSvsDebT

https://streamable.com/m6kqva

[polar acorn]

Instead of adding force, try setting velocity

[timber tide]

I actually dig the force

for those marble type games

[red igloo]

I hate it

feels slopply lol

[rocky canyon]

it feels "physicsy"

which marble games are.. ur marble game isn't snappy like arcade

lol but i guess it could be

[rich adder]

blame mass

and friction

velocity just says "fuck that we going all in"

[red igloo]

lol

[red igloo]

First of all thanks for that the movement is instant but how can I fix this? it sort of slides and doesn't look good when the ball is rolling.

https://paste.ofcode.org/JbzgEJ6dZuS9ME2DXSqJdC

https://streamable.com/zqopz5

[rich adder]

btw you should not need to use Time.deltaTime on dynamic rigidbody thats why your force are cranked so high

[red igloo]

you sure? I watched brackeys video about it and he said you should get use to adding Time.deltaTime and I think he said it messes with the fps or the monitors refresh rate or something I might be wrong.

[rich adder]

pretty sure

brackys has made everyone make this horrid mistake for years

[red igloo]

thanks for that

[tall lava]

Is there a difference from defining an on-click listener in the inspector Vs in the code? When would you want to use one over the other or is it just a design choice?

Thanks!

[rich adder]

the sliding is probably rb trying to catchup rotation with sudden switch in velocity

[rich adder]

imo the ones in the inspector are mostly useful for
designers or assets to be distribuited keep things simpler modular

they are not very good for programmers, having to look at the code gives much clearer picture of what is subscribed to what instead of peeking each time in the inspector trying to find this mystery box of events/methods

[rocky canyon]

time.deltTime is usually used for mathmatics in update

say u have
myVariable += 1;
it'll accumalte faster with a faster frame rate..

so myVariable += 1 * time.DeltaTime; evens it out..

[tall lava]

Ohhh that makes a lot of sense!

Thank you!

[rocky canyon]

but shouldnt be used with Rigidbody functions or Mouse Deltas

[red igloo]

Noted thanks

[rocky canyon]

ppl confuse time.delta time as some sort of sensitivity multiplier..

[rich adder]

also MovePosition needs Time.fixedDeltaTime (Time.deltaTime in FIxedUpdate)
cause it generally not used with dynamic but with kinematic so it needs that added consistency between frames

[rocky canyon]

changeInMouseDelta *= multiplier; would be ur sensitivity

[rich adder]

yup especially mouse. You already have the distance since last frame

but with controller iirc you need Time.deltaTime for look inputs

new input system has also extra features like custom scaling modes

[frigid sapphire]

Hi im making a game where you open crates, I had everything working untill I wanted to make the dropped item appear after opening the crate. I changed my inventory list and item array to Images so I can display them and now the timer is going down but nothing else happens https://paste.ofcode.org/XZAPuSaCh5PJmUPXtjg9pv

[rich adder]

did you start by checking console ?

[red igloo]

Why can't I move diagonally? When I press W & D wont go in that direction its as if im being blocked by a wall

[rocky canyon]

public class PlayerMovement : MonoBehaviour
{
    [SerializeField] private Rigidbody rb;
    [SerializeField] private float moveSpeed = 100f;
    
    private Vector2 moveInput;
    private Vector3 horizontalMovement;
    private Vector3 verticalMovement;

    private void Update()
    {
        moveInput.x = Input.GetAxisRaw("Horizontal");
        moveInput.y = Input.GetAxisRaw("Vertical");
       
        if (moveInput.magnitude > 1)
            moveInput.Normalize();

        horizontalMovement = new Vector3(moveInput.x * moveSpeed, 0, 0);
        verticalMovement = new Vector3(0, 0, moveInput.y * moveSpeed);
    
    private void FixedUpdate()
    {
        rb.velocity = horizontalMovement + verticalMovement;
    }
}``` should do that for ya

b/c of ur weird if statements

u should keep it simple

[red igloo]

Sheeesh THANKS XD ❤❤

[rocky canyon]

--missing--

[frigid sapphire]

Yeah I'm not getting the "Opened" log but timer is going down

[rich adder]

well yeah

you're checking ==0 on a float

the odds of that happening are pretty darn slim

floats are...tricky..

[frigid sapphire]

So would <= 0 work?

[rich adder]

0 can be 0.0000000001 and not be 0

[rich adder]

yea pretty much

[rocky canyon]

< 0 is more concrete

<= still gonna have that approximation

[rich adder]

there is also Mathf.Approximately but thats not necessary here
