Not true! Spacing out code allows air to flow through far easier, dissipating more heat, and in terms making it run faster!
Jokes aside the more I look at it, the worse it gets, even logic-wise. The if statement on line 67 cannot be reached because it's not possible to have Spawn to false if dropSet == -1 (which sets Spawn to true on line 52). The block on lines 70-73 always runs (missing else)

[crimson plaza]

Is the pastebin mentioned above some sort of tutorial that everyone follows and encounters the exact same issues

[quaint rock]

someone else might have a guide, i don't really got anything on the top of the mind or if i did it would be like a decade outdated

[crimson plaza]

My current plan is to screw around and find out, I'd assume that's how majority learn as well right

[simple egret]

No I think it's pure lack of scripting knowledge, to be honest. It's roughly the same code they've posted for the past months

[quaint rock]

it depends on the person, though if brand new to things its prolly a good idea to follow some introductory learning content

[wicked scroll]

This is invaluable

[crimson plaza]

Roger that

[crimson plaza]

Oh the same person or something?

[crimson plaza]

Thanks! I'll take a look

[quaint rock]

found when you been doing something for a very long time, it can be easy to help with specific problems but hard with more generally how to approach learning it all since its been a long time since i had to do that

[pulsar holly]

Where did you change the code?

[simple egret]

Yep same user. At least the code style improved after mods told them to format before posting, or they would be muted lmao

[spring creek]

The only change was to formatting
A very needed change

[crimson plaza]

mhm. Thanks for the advice; you'll see me arounddd

[spring creek]

There is honestly SO MUCH that needs to change, it's hard to know where to start with the logic.
But this is a good start
#archived-code-general message

[lean sail]

Considering that you've pasted (almost) the same code every single time, all with this broken logic, you definitely need to change a lot.
Like what is this script even for? How come its moving with such hard coded if statements? You would benefit greatly by just following a basic tutorial for what you want

[naive swallow]

You also need to make sure there's enough space that the code gremlins can move around. How else are they going to access your variable if it's in a giant block of text they can't fit through? Are you trying to get a NullReferenceException?

Instantiate returns a reference to the instantiated object. so you use that reference to access any public members

Hey folks! I’m trying to make a class that inherits from Unity’s Toggle class, but any public properties I add to the class don’t appear in the inspector. No console errors or warnings or anything. Any ideas? Thanks in advance.

[cold parrot]

you need to override the custom editor too

just have it call the base.OnGUI() and append your custom properties after that.

[alpine harness]

oh gosh, that makes sense 🤦‍♂️ didn't realize there would be a custom editor associated with Toggle thanks!

[kind fog]

hey so i’m trying to get all my scriptable assets from a folder and make a list on it using AssetDatabase.Find Asset but i’m unsure of how to do it. i’ve search it up too but i don’t rlly get it lol

[quaint rock]

for what purpose

it matters alot since AssetDatabase is not something you can use in builds

[kind fog]

well so i have a player locker and i have a folder that has all the scriptable objects that have the cosmetic information, sprite, all that stuff

i just wanted all the cosmetics (the scriptable objects in the folder) to show up in a list on the player locker script so it can access it without me having to put each cosmetic in the list every time i make a new one

i know it’s a bit extra but yk 🤷

[quaint rock]

so you cant use the assetdatabase for that

i would use addressables so you can mark the whole folder with a addressable label and load them all at once

[cobalt gyro]

[tight ice]

hi guys, I'm using a hingejoint and having a problem where the player Capsule only wants to go up like 80% of the way (rather than spinning the whole way around it) of the hingejoint.
this happens regardless of how much force I add to rigidbody (via _movementMultiplier)

Interestingly, when _movementMultiplier value is high enough, using a single keyPress of WASD to move the rigidbody DOES allow it to spin the whole 360 around the hingejoint.
but holding down WASD always makes it stop spinning at the pictured angle. something about holding it down is telling rigidbody to stop spinning at that angle

Any ideas? code for the rigidbody-based capsule controller: https://hastebin.com/share/yefuzamika.csharp

[dense estuary]

I figured out how to fix the slope bounce, but now I gotta reprogram the sliding.

Nevermind. This logic makes my player move super slowly down slopes, but normal speed up them.

[somber nacelle]

project the velocity on a plane represented by the ground's normal. you'll probably want to normalize and multiply by the original magnitude again so it doesn't change the speed, but it will likely work better than whatever that is supposed to do

[hexed pecan]

Their current code does the same thing as projecting it on a plane

The FromToRotation part, I mean

[dense estuary]

So my issue is that it isnt normalized?

[dense estuary]

You mean like this?

[ruby nacelle]

PostBattleUI Suggestions

[cosmic rain]

Assuming vel is not just the input vector, that wouldn't work.

[dense estuary]

vel is the input vector for the function, I use it here. And you are right, it doesnt work.

I'm pretty sure the way I have it, its multiplying the velocity by the adjusted one every frame, so it just keeps multiplying forever.

or until I'm not on a plane, which is pretty fast.

[cosmic rain]

If input normalization is the problem, you need to normalize the actual input.

[dense estuary]

Input normalization isn't the problem

My issue is when rotating the velocity I lose speed, I'm trying to figure out how to prevent that, and I was told to normalize it and multiply it by the original magnitude.

[thorny osprey]

Could someone help me out... I'm trying to test if an object has component of MeshRenderer before I'm running my function, but the GetComponent<>() here just errors out with the "Object reference not set to an instance of an object" anyways

How am i able to check it without it just erroring? is there even a way to check

[quartz folio]

1. Don't use modern null-checking operations with Unity Objects https://unity.huh.how/unity-null
2. Use TryGetComponent instead of this

3. If you're getting an NRE when you call GetComponent, then it sounds like obj is null

[thorny osprey]

try

[loud wharf]

I personally think that the get component should just throw when null.

[thorny osprey]

everything online says its supposed to just return null

but thats not whats been the case for me

[loud wharf]

Huh?

[thorny osprey]

meant to be ty lol

[spring creek]

Why do you say that?

[thorny osprey]

it mightve just been an oversight and what vertx said, 3, could be happening

[cosmic rain]

It would return null if the method is valid to invoke

[spring creek]

3 is definitely what is happening
Otherwise the error would be in a different place

[thorny osprey]

but i wouldve thought that even if that was the case, trying getcomponent on a null obj would still return null

[cosmic rain]

You can't do null.GetComponent

That's invalid

[loud wharf]

That throws null reference exception.

[cosmic rain]

Because null doesn't exist.

[cosmic rain]

You can't take out items from a box that doesn't exist. It doesn't make sense.

[loud wharf]

(The box is your obj in this example)

[vocal bramble]

Has anyone done Sebastian Lague's procedural generation tutorial I'm having some questions about it

[spring creek]

Best to just ask the questions

[cosmic rain]

Many have, but you should still phrase your question such that it's not dependent on the tutorial.

[vocal bramble]

It kind of is but I'll try

[cosmic rain]

Because even if we did watch the tutorial, chances that it was in the last few days and we remember any of it are very slim.

[vocal bramble]

Fair point

If I had a mesh which has a seed that completely changes the mesh shape, how could I create a mesh collider that gives collisions to all the seeds that could be generated

[cosmic rain]

You would need to generate each mesh and assign it to the collider.

Or use an approximation, like a sphere collider

[vocal bramble]

I'll look for some other ways cuz there can be like 2 million seeds and I need a pretty exact collider

[cosmic rain]

Why do you need a collider for all of them at the same time? Is that a quantum object in superposition or something?😅

[vocal bramble]

Oh no I mean that when a play randomly gets a seed there is that one collider for that one mesh

[spring creek]

Then why not dlich's first option?

[vocal bramble]

But there can (randomly) be many different maps/meshes that need their own collider

[cosmic rain]

Then just assign the mesh to the collider at runtime🤷‍♂️

[vocal bramble]

Because there’s practically infinite (around 2 million or something)

[vocal bramble]

I’ll try that

[spring creek]

You're going in circles

[spring creek]

That was the original suggestion

[vocal bramble]

My bad

[cosmic rain]

I'm pretty sure Sebastian Lague handles colliders generation for his procedural terrain as well in the tutorial.

[ruby nacelle]

Hey! I opened a Thread so it's easier to find but if anyone gets a second I would greatly appreciate some advice

[simple ridge]

Hi everyone, this is a bit of a more information based question then one on implementation advice, but I've been using UGUI for a while now and I've always had the assumption that it is a bad idea to let images, buttons and so on off the canvas (specifcally rotating them, moving them on the z or putting them outside the canvas border). That said however, this has always been from a perspective of neatness. I have been working on several different projects where a button for example would be placed quite far off of the canvas it was attached too, is there actually a specific code / implementation based reason this would be a bad idea? For example, are their cases where rendering would fail, or the Raycast wouldn't hit?

[latent latch]

You could just disable the button

but otherwise I don't see a big deal

[fallow veldt]

Right now I have a line render that generates a random line and a border for that line (2D game), and I need to add a collider to the outside (there will be other rigid bodies inside of it that I don't want escaping). Because the lines are randomly generated, I cannot add a collider like normal, does anyone know how i could do this? I think it would look something like this (see attached image) when viewing the colliders

[leaden ice]

Use EdgeCollider2D

[craggy veldt]

is this how you'd you get the total time(duration) of an animationCurve?

var time = animationCurve.keys[animationCurve.length-1].time;

getting the last one would be correct or should I sum them all up from the very 1st index?

[latent latch]

the last key should indicate the total time

[craggy veldt]

oh ok, thanks 👍

[restive falcon]

hello does anybody here know how to calculate the angle between 2 forward directions in unity? im trying to get the angle made when my camera is currently looking at relative to the forward direction of another game object Im using as my world forward the two objects are roughly in the same position

[latent latch]

Mathf.DeltaAngle probably

[deft timber]

Vector3.Angle

any will work

it's simple vector math

[restive falcon]

I've Vector3.angle and it doesnt work

[deft timber]

Vector3 dir1 = obj1.forward;
Vector3 dir2 = obj2.forward;

float angle = Vector3.Angle(dir1, dir2);

[restive falcon]

also its limited to 180 degrees? Im looking for a solution that will give me 360 degrees

[deft timber]

https://docs.unity3d.com/ScriptReference/Vector3.Angle.html

yes, it's from 0 to 180

[restive falcon]

this is for a radar im implementing in my game and I wanted to make a cone to represent where im currently looking at

[latent latch]

if you need the inverse just subtract from 360

[deft timber]

if you want more than 180 degress

use Dot product of these vectors and then Mathf.Acos

Vector3 dir1 = obj1.forward;
Vector3 dir2 = obj2.forward;

float dotProduct = Vector3.Dot(dir1, dir2);
float angleRadians = Mathf.Acos(dotProduct);
float angleDegrees = angleRadians * Mathf.Rad2Deg;

something like that, might be spelling errors

[restive falcon]

the problem is that forward isnt world forward so I need it to use the forward of a transform im currently setting as the world forward

[restive falcon]

let me give that a try

[restive falcon]

does the order matter here? object1 = world forward and object 2 is camera forward?

[latent latch]

if it's a local forward there may be a method for it, but otherwise you can probably use transform point and derive a direction with that

[deft timber]

why would it matter

[restive falcon]

im asking if it does

[latent latch]

https://docs.unity3d.com/ScriptReference/Transform.TransformDirection.html

ah ok there is one

[deft timber]

[restive falcon]

didnt work the angles once it reaches 180 then starts to decrement

[deft timber]

worked always fine for me

to measure angles between 0-360

if you have a direction vector (1,0,0) and (0,1,0) it should return 90 degrees

dot product will be 0 between these vectors

how did you implement it

actually, wait i think that Mathf.Acos is also limited to 0-180

  Vector3 dir1 = direction1.forward;
  Vector3 dir2 = direction2.forward;

  float angleRadians = Mathf.Atan2(Vector3.Cross(dir1, dir2).magnitude, Vector3.Dot(dir1, dir2));
  float angleDegrees = angleRadians * Mathf.Rad2Deg;

that should work now

[fervent furnace]

offset the angle by 360 - the angle if < 0 or angle= (angle+ 360) % 360

[deft timber]

yea or this

althought atan2 with cross/dot should work just fine

[restive falcon]

still the same. . . doesnt go beyond 180

[deft timber]

🤔

show how did you implement it

[restive falcon]

I used your formula as sent here

[deft timber]

add this

to the end

angleDegrees = (angleDegrees + 360) % 360;

[restive falcon]

still the same even with this added. . .

[deft timber]

then your implementation is wrong

if angleDegrees is 210 for example

then 210+360 = 570

and 570 % 360 = 210

so it should be exactly 210

[restive falcon]

is there a voice chat we can use so that I can demonstrate this?

[deft timber]

no

just show the code

[restive falcon]

        Vector3 dir1 = worldForward.transform.forward;
        Vector3 dir2 = cameraGO.transform.forward; 
        float angleRadians = Mathf.Atan2(Vector3.Cross(dir1, dir2).magnitude, Vector3.Dot(dir1, dir2));
        float angleDegrees = angleRadians * Mathf.Rad2Deg;
        float angle = (angleDegrees + 360) % 360;

[deft timber]

the entire class

where do you use it

and the console debug log values

also transform.forward is a local vector

[lavish frigate]

Hey all, im trying to linearly interpolate between two points. These are 0.5 and -0.5 on the Y axis. The object is moving way beyond these points though. Am i missing something here? This script is attached to the object.

[deft timber]

if you need them in global vector, then use Transform.TransformDirection(Vector3 dir)

it transform local direction to world space

[fervent furnace]

tf.pos+=vec3?

[lavish frigate]

might i need to multiply that by deltatime?

[deft timber]

no, dont use +=

[restive falcon]

ok so world forward is a transform im using for my north and the camera moves around based on where im currently facing right. this is for a radar implementation so if the camera is facing the same direction as the world forward, the angle should be 0 and so on depending on where im facing

[deft timber]

read what i said

and adapt your code

[lavish frigate]

ah i realised now i shouldve kept track of original pos

is there a way to check if script is running in OnDrawGizmos?

[deft timber]

just do = instead of +=

[fervent furnace]

val+=lerp(100,1000,fraction);

just float case, not vec3

[lavish frigate]

my points are relative to the things world position so im now doing = with original pos

it works

[deft timber]

nice

[lean sail]

What do you mean if the script is running? What does running mean in this sense

[deft timber]

private bool hasStarted = false;

private void Start()
{
    hasStarted = true;
}

public void OnDrawGizmos()
{
    if(hasStarted)
    ////
}

i guess?

if that's what they meant

[lavish frigate]

In game, so i used Application.Isplaying

[urban lintel]

How do you architecture the following:

1. I have a circle spawner script, which handles spawning some circles and parameterising them
2. One of the parameters is something like an item, which on death of the circle, should appear in the UI

I'm roughly familiar with events/delegates/observer pattern, and have a brief idea of how one would go about it, but not entirely sure.

Would the circles invoke an onDeath event? If so, I'm assuming the circleSpawner can do something with that information, but what about the link between the circleSpawner and UIManager, how should those communicate

[deft timber]

fire OnDeath event

subscribe to that even with all dependant systems

and so your stuff

update ui etc

[urban lintel]

So if my circleSpawner has a reference to the created Circle, what am I doing to expose that circle's onDeath event to the UI manager. Should the CircleSpawner also throw an event that the UIManager accesses through a reference to CircleSpawner?

[thick terrace]

that should work fine, you could have an CircleDied event on the spawner, or an alternative would be have a CircleSpawned event where your UIManager could add its own listener to each circle when it spawns

[tardy crypt]

Use a free, already existing system from the asset store? No, I only need a very simple version of this thing, I’ll roll my own. <2 years later>. I just wasted a ton of effort rebuilding a crappy version of the free asset for no reason.

[humble pumice]

If I have a bunch of objects that represent chunks, with a script with no active code containing its data on all of them and all their contents as children. Will those alone still impact performance if there are too many of them? I am planning on leaving them active while keeping their contents disabled (if the player is far enough away).

[cosmic rain]

Probably not enough to tell the difference.

[fossil shadow]

Anybody know why WaitAsync is seemingly missing? It was added back in .net 6, so it should be available, right?

[chilly surge]

Unity doesn't use .NET 6 (or any .NET Core)

ah, right, I was mixing up .net version and c# version

hey everyoneee just wondering if its better to handle data on scene transition one way or another

say in my scene I have an array of bools "originalArray" that sits on a component (which will be destroyed during scene transition) and I want to keep that it, would it be better to have an array point to this array so that it stays in memory even during the scene load (by just doing keepArray = orignialArray) so that i can then continue to use it after loading the new scene by just "holding on" to the array, or would it be better to make a completely new array like basically clone the entire thing, hold onto the CLONE in a scriptable object and then repopulate the original array component when were in the new scene?

basically 1) would be just point to array using another array using a scriptable object or 2) would be clone array and then repopulate the array on the component in the new scene

basically asking if theres a massive difference between them because if i do this for large amounts of arrays and even dictionaries then it could maybe increase load time?

both methods would be using a scriptable object, the main difference is cloning vs pointing to and keeping it in memory

wont do disk saves because that is a bit unecessary for temp data

[deft timber]

unles you have A LOT of objects it doesnt make a difference

A LOT meaning milions iterations

[next seal]

okay i wont, good to know, but lets pretend it is a large amount of data which one would be more efficient just like time and resource wise?

thank you first of all but also i do also just wonder about that for curiosity sake

I would assume they dont really have a big difference even with large data?

[deft timber]

pointing to a existing address in RAM would be more efficient of course

instead of creating new array containing milions of elements

but the best approach with such big data woul be external saving to a file

or as a json

[next seal]

do you think I should repopulate the component in the new scene at all or is it fine for my data to just live its best life on the scriptable object since its temp data

disk writing is slowest no?

isnt memory keeping much much faster than disk I/O

[deft timber]

with SSD? its for sure much faster than creating a milion elements array in a for loop for example

what exactly are you trying to do

any tldr?

want to keep array between scenes?

[next seal]

right if we talk about millions of elements once again iguess so, but when we talk about a tiny amount of data again then memory should be faster again right?

[deft timber]

again as i said, it wont make any difference

maybe in miliseconds

not something you will notice

[next seal]

yea but not only between scenes, im wondering if i should just let my array live in the scriptable object permanently

[deft timber]

performance-wise

[next seal]

as this data needs to be accessed from all kinds of sources

[deft timber]

but what is that array containng

what type of data

is it persitant data or does it change runtime

[next seal]

and its such a neat approach with like nto a lot of components that then depend on one another when you have a universal data SO right?

[deft timber]

you have several approaches

1. singleton + DDOL
2. scriptable object

i'd avoid cloning the array

between each scene transition

bad idea

[next seal]

its game state bools basically

[deft timber]

then yea, make it a singleton and DDOL

[next seal]

I heard bad things about singletons

I am a new programmer and want to like adopt uhh healthy practices lol

[deft timber]

if used incorrectly they are "dangerous"

it is a helthy practice

[next seal]

is the danger that components rely on one another and if the system changes the entire code ahs to be changed?

or is there more danger?

[deft timber]

for example, this is my project

i have all the managers i want to access globally

as a singleton, DDOL

so i can access GameManager.Instance in any scene etc

[next seal]

yea i mean if its fine and save to just point to and keep in memory thats prolly what i will do

[deft timber]

just really, do the singleton+ddol

for global managers

cleanest and fastest way

[next seal]

but you cant access them from other scenes right?

[deft timber]

you can

that's the entire point

[next seal]

YOU CAN? I thought thats illegal in unity

[deft timber]

do you know what's DDOL?

[next seal]

no not really

[deft timber]

look on that screnshot again

do you see DontDestroyOnLoad?

[next seal]

I just have had that issue before where i had a "ESSENTIAL" scene but then my other objects were unable to refrence those components

and I really wanted to refrence sometimes.. like not all the time but there were instances where I wanted to do that

[deft timber]

basically it NEVER gets destroyed

    print("HingeJoint.spring: " + hinge.spring);
    print("HingeJoint.useMotor: " + hinge.useMotor);
    print("HingeJoint.motor: " + hinge.motor);
}```

```cs
HingeJoint hinge = part.gameObject.AddComponent<HingeJoint>();
hinge.anchor = Vector3.zero;
hinge.axis = Vector3.up;
hinge.connectedBody = gameObject.GetComponent<Rigidbody>();
hinge.connectedAnchor = new Vector3(2.12f, -0.06f, -1.94f);
hinge.autoConfigureConnectedAnchor = true;
hinge.useLimits = true;
JointLimits limits = hinge.limits;
limits.min = part.hidgeJoint.min;
limits.max = part.hidgeJoint.max;
hinge.limits = limits;
hinge.useSpring = false;
hinge.useMotor = false;

but it doesnt work at all, when hinge joint is added from editor window it works, but from script its buggy a lot

does anyone have any idea why it behaves different when created from script?

[deft timber]

it's like a additional scene

to your main scene

[next seal]

oh yea dont destroy on load ive heard of that

[deft timber]

so whenever you transition

your game manager and gold manager etc

will "follow"

[next seal]

but then how do your actual gamescenes access any of the universal systems? they cant refrence them right?

[deft timber]

they can

that's why they are a singleton + ddol

let's say you are in main menu

and you want to access your game manager

[next seal]

does unity then say ah nevermind thats allowed?

[deft timber]

then you do GameManager.Instace.

[next seal]

because when i had a essential scene with my systems all my cross scene refrences werent working

[deft timber]

if you are in game scene, you can also do GameManager.Instance

[deft timber]

beceause it wasn't ddol

[next seal]

ohhh with instance huh

i see

[deft timber]

and without a singleton

make your manager a singleton, and DDOL

[timid depot]

anybody?

[next seal]

yea no they were DDOL i just didnt know the shorting for it, i know dont destroy on load

[deft timber]

that's your job

[deft timber]

okay then they werent a singleton

so you couldnt access them from other scenes

make a GameManager, make it a singleton, make your array in that GameManager, mark it as dont destroy on load

boom, now you can access GameManager everywhere

in any scene

[next seal]

i probably did it wrong yea that was a long time ago

I am probably gonna stick with the nonsingleton approach for this project because i will need different kinds of like systems for different scenes as the mechanics will be nt the same

[chilly surge]

Explicitly making a copy of the data and then operating on it, is a fine solution too, it guarantees that you have full ownership and control of the data and not constrained by the original data (eg if the original data is meant to be immutable, now you have the freedom to mutate the copy as you see fit)
Any sort of global state like singletons or statics have their downsides, but I have a feeling that it might not be something you need to worry about just yet.

[next seal]

Right but Singletons are really useful for scenes where the mechanics and systems dont change mostly right

like the systems needed in the different scenes differ and I really only need to carry a small amount of data

but if I was making a mechanically not changing game like a platformer id prolly do that now :D

I was really mostly worried about cloning data vs just pointing to it in RAM

[chilly surge]

Yeah the singleton/static is mostly a tangent, for cloning refers to first half of my comment. It's a fine approach, but obviously not cloning is faster, so it's up to you to decide whether the pros outweighs the cons.

[next seal]

Yea my plan was just to keep it in memory because, I mean, performance but it really doesnt matter that much on small scale

[fervent furnace]

you should know what mmap is

[next seal]

havent profiled that much yet because to profile you need a game to profile and not just some basic systems :D

[chilly surge]

The singleton/static point, even for a system that never changes and has only one implementation, it still means that it becomes a hard dependency. Any system that relies on a singleton/static/any sort of global state, now cannot possible exist without it or change it.
Changing it is still useful for testing, and even if you don't care about testing your code, the fact that it being a hard dependency means that your system literally cannot run unless the hard dependency is initialized. This most commonly manifest as the problem of "I initialize my singletons/statics on a boot scene and make them DDOL, but now if I want to start from a particular scene I can't anymore, I have to find some way to still initialize them."

[next seal]

and i mean its better to ask first whats performant rather than just do trial and error with everything right?

at least with those things that wont be apperant until late in development i feel

[next seal]

Thats exactly why I havent touched singletons anymore since my like very firsts attempts in unity

I find the design idea around singletons like very understandable the wanting to have this overarching system but at the same time I love flexability to just completely scrap systems without having to redo other stuff

[chilly surge]

Well it's certainly not saying singleton/static/global state are true evils, everything has pros and cons, just like your original question of "should I make a copy or just reuse the data"

[next seal]

Right exactly singletons are useful

[chilly surge]

Understand the pros and cons, weigh them yourself to see if they are relevant to your particular use case, then decide from there.

[next seal]

Right, thank you

[fallow veldt]

Do you know how I can add the collider to the edges?

[leaden ice]

It's the opposite, you add the edges to the Collider

[cold egret]

• Hey. I'm constructing a render params instance and i need to set its rendering layer mask. The default layer mask can be casted to int; however, the parameter in the render params type is uint. Am i supposed to convert those using unsafe utility to reinterpret the type, or have i missed the actual way?

[hard viper]

Singletons are great when they apply.

I don’t really see any drawback in using Singletons in the scenarios where they should be used.

And if something shouldn’t be a singleton, it prompts the question of “why would you make X a singleton”

[meager pendant]

which is more readable:

before or after

[deft timber]

neither

why don't you keep the dialogues in scriptable objects for example

or fill them through inspector

[meager pendant]

no i think its better to store all the dialogues in one place and segment them into scenes

it will keep things all in 1 place

[hard viper]

to your question, if you have default arguments, you should use them.

But dialogue should be in scriptable objects, not code

[deft timber]

but why not in scriptable objects

imagine you wnat to add translation

to your game now

to other languages

[hard viper]

this violates the open closed principle

[deft timber]

that will become very unpleasant to work with

on larger projects

for sure not designer friendly

not translation friendly

and just not dev friendly at all 😄

[hard viper]

this should 100% be done on scriptable objects, or other sorts of files that can be parsed by your code

i think there is a plugin called yarn weaver or something for this

[meager pendant]

how so

[deft timber]

read again

what i wrote

and what @hard viper wrote

[hard viper]

we are literally explaining to you why it is a problem

[meager pendant]

right now all i have to do is copy the dialogue object from 1 npc to another and then change a value in the npc so i can fetch their dialogue from the manager

shouldnt be a problem at all lol

[hard viper]

🤦‍♂️

[deft timber]

do whatever suits you then

[hard viper]

and… how much dialogue is going to be in your game?

if you have actual decision trees here, it sounds like a fair bit

[meager pendant]

at most it will take up like 3mb of memory lol

[deft timber]

its not about the memory

its about work ethic

[hard viper]

this is not a memory issue

it’s an architecture issue

[deft timber]

im out of this convo, explaining things like that makes my energy drained 😄 good luck tho 😄

[chrome berry]

History Lesson:
Dialog in JRPGs back in the 8bit and 16bit days was done this way. Hence why translating the games for foreign markets always had a long delay of months or longer, because all the strings were in code rather than separate data.

[meager pendant]

now that is a good reason to do it separately

that makes sense

[hard viper]

xaxup literally said that earlier lmao

[chilly surge]

Tbf if you use the "a pattern should only be used when it applies" then there's no bad pattern in the world according to that definition 😄
Most "bad" patterns are bad in the sense that the cons are not immediately obvious especially to first time users of the pattern, and it only emerges later on. Singleton for example is very bad if later on "there's a new scenario where the system is different unlike before where the system was always the same hence I used singleton, now it's a giant refactoring effort to get rid of it." Yes you can say that "well if you knew this was coming, then you should've never used singleton" but the problem is that you don't always know what the future has in store for you. Requirements can always change on a whim.

[meager pendant]

true i didnt notice it

my bad

[hard viper]

the conditions for Singletons are usually relatively obvious

[hard viper]

and even without translation issues, you should understand the open closed principle to know why what you are doing has deep problems

[chilly surge]

Evidently not with how many people abuse it and regret it later on.

[meager pendant]

i dont know about the open closed principle

[hard viper]

pain is the only cure for foolishness

[hard viper]

look it up. learn

[chilly surge]

Well the point about singletons being hard to get rid of later on still stands, and like I said that point is not something you always have the fortunate foresight to decide because requirements can change in the future.

[deft timber]

that sounds literally like a sentence from Darkest Dungeon game

[hard viper]

that is true. but you need to be aware of what sort of committments you make with singletons

[latent latch]

this is why service locator pattern should be what's thrown around more and not singleton

[hard viper]

like, when I make a camera controller singleton, I commit to only having one camera. That is a committment that I make actively, and cannot take back

making things more generic than they need to be can cause issues. So i do not want to start making code to leave room for a second camera

if you are not ready for this committment, you cannot make a singleton

[latent latch]

You make a class as another abstract layer of a class which you access that has references to the cameras. This way you can add as many cameras as you want without having to make this camera class a singleton.

[chilly surge]

There are other patterns which can replace singleton (service locator being one example brought up) that doesn't incur much more cons yet give you the flexibility that singletons lack.

[hard viper]

yeah, but I know that my game will not ever support multiple cameras because of the nature of how the camera works in my game. I do not need to add layers that I know do not need to exist.

[hard viper]

in my eyes, if you cannot know with certainty that you always want a class to have a SINGLE instance, now and forever, you are not ready to make a singleton.

it is a committment

the lack of flexibility has pros and cons

[chilly surge]

And "now and forever" is an extremely harsh condition, you are essentially predicting the future, and that's what makes singleton bad.

[meager pendant]

so for dialogue i should have files with text stored and then have separate files for each language i want to translate to, then when language is changed / when the game starts i load/reload the dialogues by reading lines in the file

[hard viper]

there are some things where you do know that.

[knotty sun]

That is why we design software rather than just making it up as you go along

[hard viper]

if you don’t know or aren’t sure; then you can’t make a singleton

[chilly surge]

Exactly, and accepting that "we can't always predict the future" is part of the design process.

[hard viper]

it is. but you need to have a general idea of your needs to not make things way more generic than they need to be, which wastes time

[hard viper]

https://www.yarnspinner.dev

[chilly surge]

Vast majority of the usages of singletons are simply not fit, and again like I've already said, I'm not saying singletons are always bad, but it's commonly considered a bad pattern for very good reasons. "A pattern is not bad if you only use it in the situation it fits" is not exactly a good defense, because "the situation it fits" for singletons is very narrow.

[knotty sun]

Spoken like a student

[meager pendant]

like

Author|Index|Dialogue|ResponseNumber
Index|Response|DialogueIndex

System|0|Hello, World!|2

System|1|Nothing much.|1

[hard viper]

don’t be a dick, steve

ad hominem is not cool

[hard viper]

Look at this system: https://www.yarnspinner.dev/

[knotty sun]

but it's true. When you design software you analayse the requirements and you implement what best fits the need. Saying don't do this, don't do that is just plain nonsense

[hard viper]

then you should say that instead of name-calling

[knotty sun]

because it's always students that spout theoretical bullshit when they have no real experience

[meager pendant]

id rather make my own from scratch otherwise it wont be as fun

[hard viper]

the more you do not know the design parameters of what you are making, the less you can use singletons. This is more true in bigger projects where multiple people are working on something with different ideas. And then corporate changes their mind on feature set

[meager pendant]

in theory, if you took the stick out of your ass do you think you'd be more approachable?

[knotty sun]

not a chance

[hard viper]

you catch more flies with honey than vinegar

[deft timber]

it's very true

it's the same as when you are on your car driving lessons

you dont learn how to drive at all

[meager pendant]

you were once a student too steve

[chilly surge]

Welp, the conversation was back and forth in good spirit with everyone bringing up good points, now I see it just devolves into name calling and assuming about people's experience to discredit arguments, so I guess this is my cue to exit.

[deft timber]

you only learn how to pass the exam

and then you learn the learn driving skills later when you gain road experience

[meager pendant]

ive never been in a cs class so i wouldnt know

[knotty sun]

true, 50 years ago

[chrome berry]

No, you must pick a side, and then rabidly attack the ones waving the flag that has a different colour than the one you are waving 😄

[meager pendant]

i do have a friend who is taking one and the stuff she has to do for class is the most useless and stupid stuff

[hard viper]

i’m sad to see it devolve like this. we might have a better convo in the future

[meager pendant]

idk why they teach html in a cs class

[hard viper]

is html even turing complete?

[deft timber]

you picked the wrong school, fool ~Big Smoke

[knotty sun]

of course it's not, it's not even a programming language

[meager pendant]

its not

[meager pendant]

yeah html should be taught in web design or art classes

not cs classes

[hard viper]

i ask because why the hell would you teach a non turing complete system for introductory cs

[spring flame]

https://stackoverflow.com/questions/2497146/is-css-turing-complete

[cosmic rain]

computer science is a wide field.

[hard viper]

i would not call web design cs

web design is more like art generated by text interpretted by a computer, than a programming language

[deft timber]

it's a sign language

[knotty sun]

the name says it all
Hyper Text Markup Language. I.e. nothing whatsoever to do with programming

[meager pendant]

"so i just graduated college, finally got my cs degree after months of working with html. time to get into the workforce? oh whats this? c++? never heard of it."

[cosmic rain]

While writing html might not be part of cs, understanding how it works, might.

[hard viper]

an interpretter for html, yes

teaching html, no

[meager pendant]

i mean

the cs teacher at my school teaches it like that except instead of just using html they use python and a game engine

so they actually understand how its working because they have to do it themselves

[cosmic rain]

html and python aren't really interchangeble terms xD

[knotty sun]

And how many people (apart from me) actually write html rather than use a crappy framework to do it for them?

[meager pendant]

i mean the stuff they are doing is

[deft timber]

probably quite a lot

[meager pendant]

you can say it like this

if you learn html you will be good at making websites and thats pretty much it

but if you learn an actual language you can pretty much do anything you want

[knotty sun]

no you won't. making good websites needs much more than just html

[meager pendant]

ok let me rephrase

you will be good at making websites look good and be well formatted

[deft timber]

by learning html?

[knotty sun]

still wrong

[deft timber]

no

[meager pendant]

ok well i dont make websites so im just speaking from what i know

[deft timber]

typical then 😄

[meager pendant]

but if i paid for a cs course and i got taught html id be pretty pissed

is all im saying

[deft timber]

that doesnt make sense at all

it's like

you paid for a car and got a ps5 console

how did you connect c# course to html course

[meager pendant]

my friend has been in a college cs course for years and they just went from html to javascript like months ago

[deft timber]

then he picked weird fucking college lol

[meager pendant]

no thats like all colleges

from what ive herad

[deft timber]

then you've heard wrong

[cosmic rain]

I mean, if html is just one small part of a course that encompases a lot of other stuff, like C#, C++, OOP, etc... Then why not?

[knotty sun]

yep, dumbed down the complete learning of cs and yet students still have the chops to pontificate

[naive swallow]

Very incorrect

[meager pendant]

they teach it like its a web design course

atleast the school my friend is at

im not convinced she isnt going to the wrong classroom

[naive swallow]

Then your friend is at a shit school. Probably a diploma mill like university of Phoenix or DevVry

[deft timber]

then as i said multiple times, your friend picked some very special shit school

or you understood him wrong or he's lying

[hard viper]

or his friend doesn’t know that web design isn’t programming, which is the most likely

[meager pendant]

im pretty sure its the university of Sidney australia

[naive swallow]

There are web design courses at legitimate schools, but they're self contained and usually elective. My CS program didn't even offer any

The 100-level courses were taught in Java, after that it was either C or language-agnostic

[meager pendant]

ive gtg now

[hard viper]

i find it more likely to be a communication issue than the school being so bad as to have a CS program that starts with html

[deft timber]

yea there's no way

[knotty sun]

what? No ASM, that is so sad

[fervent furnace]

first language course is C

[hard viper]

every following teacher in the CS program would immediately realize their students didn’t know anything that they were expecting as prerequisite knowledge

[hard viper]

my condolences

[fervent furnace]

i heard the first course will switch to python

[naive swallow]

No, there's assembly. That's part of what I consider language-agnostic. All languages become assembly at some point

Teaching cs concepts unrelated to actually making a program in a language

[hard viper]

i started with python. learn with training wheels. Then learned C, to learn the low level shit at play. Then C++ to build up

[naive swallow]

Like algorithms, assembly, design, etc.

[hard viper]

then other classes were purely theoretical

[knotty sun]

good, I thought you were talking about logic and analysis as language agnostic

[slow shoal]

yo anyone is here?

[deft timber]

stop spamming and crossposting

[hasty canopy]

Wish I had dontasktoask copied on my clipboard

[deft timber]

not hard to remember

dontasktoask.com

https://dontasktoask.com/

[slow shoal]

me?

[deft timber]

yes

[slow shoal]

How so

[hasty canopy]

O nice

[deft timber]

crossposting is against the rules

[slow shoal]

I realized the problem i was facing wasn't beginner coding

[deft timber]

not related, don't need excuses, just saying ;p

[thin aurora]

I'd rather have a plain HTML website than some oversaturated mess implementing all current cool frameworks

[deft timber]

still, cannot make a good website just with HTML

that was the point

of entire conversation

atleast css+js

[surreal blaze]

depends what it's for

[thin aurora]

Sure, you need a bit of css sparkle if you want to do anything that looks good on the eyes

But this whole thing is incredibly opinionated and depends on context

[deft timber]

yup

[slow shoal]

Alright

[knotty sun]

agree absolutely, which is why I never use frameworks

[thin aurora]

That's not exactly my point though 🤔

I mean it's really not a problem if you use a framework. If you got time to do it yourself, by all means go ahead. But there are existing solutions that also work

[knotty sun]

there is no 'one size fits all' solution to any computer system implementation

[deft timber]

noone told there is

[knotty sun]

that's what frameworks profess to be

[fossil shadow]

wasn't the point that learning HTML (and CSS) is used almost exclusively for making websites and nothing else (except UI in a few games), so spending time on it is not useful for CS?

[fossil shadow]

never heard of a college teaching only HTML+CSS (assuming you misunderstood and it's CSS too) in a CS course, except maybe on design focused ones. But then it's not a CS course but a design course at a CS college.

[fervent furnace]

i think they will teach you full stack instead of just front end

[west lotus]

https://motherfuckingwebsite.com/ css was a mistake

[knotty sun]

that is putting it very, very politely

[dense estuary]

However, normalizing it and multiplying it be the input velocity causes it to multiply every frame, shooting me off the screen.

[icy rock]

hello my gamemanager script is for some reason running twice and i get twice the amount of "points" every second than i should be getting anyone know how to solve this?

[dense estuary]

You need to provide more information than that, like, for example; your script.

[icy rock]

ill send the script soon

does this work?

[spring creek]

Yep. Where do you call Increment?

[icy rock]

im pretty new to this so maybe i should ask these questions in code-beginner but i use the Increment function as when i press the button it increases (i feel like i dont understand your question completly)

[spring creek]

I'm asking WHERE you actually call the function. Somewhere you would have written Increment() to actually cause it to happen

It looks like it would be in a different script if that helps

[rigid island]

I think they mentioned UI butto's onclick

[spring creek]

Ahhh ok

Maybe show the inspector for that button

[rigid island]

what is Multiplier amount, and why are u not debug.logging these values to make sure they are correct

[icy rock]

it was in a different script but i moved it to the gamemanager (long story) and it works just that the money per sec is double of what it should be

[icy rock]

one

[rigid island]

are you sure you dont have the script twice or something?

[spring creek]

You're still talking about the declaration. I'm talking about the call

[icy rock]

that was what i was thinking but i checked it like 10 times and i dont run it twice

i am stupid you were right i do run it twice sorry

[rigid island]

thats good, at least its solved now yes

[icy rock]

i have coded the entire day so i guess my brain has just melted and my last braincells are gone

[rigid island]

haha yeah,good to give the brain time to breathe once in a while

[icy rock]

but i have one more problem in my script, i use playerpr

oops

when i press r all values should go back to their normal state but it doesnt work ever since i moved it from another script into the gamemanager script

this worked but isnt anymore

[rigid island]

what makes you say that

btw your variables are static , that might have to do with it

those need to be manually reset as wel

I personally would not use static for this

[heady iris]

how do you know it's not working?

if the problem is with anything other than the player pref values, then this code is the wrong place to look

[icy rock]

cause when i press "r" money and money per second should return to 0 but they dont

[heady iris]

this code resets your player prefs

it doesn't do anything else

[icy rock]

yes i know but playerprefs is my saving system i can try to take a bigger screenshot

[heady iris]

int x = 123;
PlayerPrefs.DeleteAll();
print(x); // logs 123

I know it's your saving system

[icy rock]

does this change anything

[rigid island]

why would money per second return to 0 if you're only changing playerprefs

[heady iris]

Why do you think resetting the playerprefs values is going to do anything to MoneyPerSec?

[heady iris]

this is an identical situation

[icy rock]

before just the money per sec was not resetting but after that line of code it did

[heady iris]

Your code does literally nothing to change MoneyPerSec after the game starts

Of course MoneyPerSec isn't changing

[icy rock]

this is my upgrade code when i buy shit and it updates after every purchase and sets the playerprefs to the desired value

[rigid island]

!screenshots

[tawny elk]

No

Be mindful, if someone requests your code as text, don't send a screenshot!

[heady iris]

Yes. It sets the player prefs values.

[rigid island]

here's their code
https://hastebin.com/share/openofiruv.csharp

[heady iris]

PlayerPrefs.SetInt("foo", 100);
int val = PlayerPrefs.GetInt("foo");
PlayerPrefs.SetInt("foo", 0);
print(val);

What value does this log?

[rigid island]

Im gonna go ahead and say cause they're static xD

[icy rock]

yes so by pressing r the values should go back to the start values which are 0

[heady iris]

What value does this log?

[icy rock]

100

[heady iris]

Correct.

That's exactly what your code is doing

You're never resetting MoneyPerSec. You're only resetting the PlayerPrefs value.

If you want to reset MoneyPerSec, then you need to..well, do that

[icy rock]

it was working before so thats confusing

but so it should just be if(Input.GetKeyDown(KeyCode.R))
{
MoneyPerSec = 0;
}

i thought that beacuse the playerprefs value of mps(money per sec) was changing with every purchase setting it back to 0 with the press of "r" would work, according to a tutorial i saw it does

[heady iris]

int x = 100;
PlayerPrefs.SetInt("foo", x);
PlayerPrefs.SetInt("foo", 0);
x += 5;
PlayerPrefs.SetInt("foo", x);

What value is written into the player preferences?

[icy rock]

five

[heady iris]

Why?

Where did I ever assign a 5 to x?

[icy rock]

+= 5

[heady iris]

And what was the value of x on that line?

before x += 5 was evaluated

[icy rock]

zero

[heady iris]

Why?

[rigid island]

basic math myg

[heady iris]

PlayerPrefs.SetInt("foo", 0);

How does this line of code set x to zero?

[icy rock]

oh

[rigid island]

100+5 is not 0

[heady iris]

the answer is that it does not

x is still 100

it doesn't matter that you happened to use x when setting the playerprefs value earlier

there's no "link" (that'd be extremely weird)

[rigid island]

yup, you only load it on Start

[heady iris]

Setting a PlayerPrefs value does nothing to any of your variables

It just changes what PlayerPrefs.GetInt will return later

That's it. Nothing else.

[heady iris]

You probably used to assign MoneyPerSec = 0 while resetting

or you then read a value from PlayerPrefs and wrote it into MoneyPerSec

or that variable didn't exist at all and you were always reading from PlayerPrefs

[icy rock]

can i send you a yt link

its baisically the code that i stole but its working

[heady iris]

then it does something different

[icy rock]

can you take a look since i have a slight feeling you understand c# better than me

[heady iris]

if you can point me to the specific part that shows the code, yes

[icy rock]

did you get the vid?

[heady iris]

just post it here.

[icy rock]

didnt know you could send yt links here

[heady iris]

pressing R doesn't instantly reset the values in the video

it just makes it so that, the next time you launch the game, the playerpref values have been reset

[icy rock]

yes but that is not working for me

its just a way for me to delete all of my progress before i release it

[heady iris]

okay, I thought you were asking why it wasn't immediately resetting the numbers

It's probably the same issue, though

• reset prefs to defaults
• something writes to prefs
• game quits

the old values are back in your prefs again

especially if you added code to write to PlayerPrefs when the game quits

[meager pendant]

yo

how do you use this

in a script

i have tried google

[steep herald]

was google graced with a better description

[heady iris]

this looks like Visual Scripting

[rigid island]

#763499475641172029

[earnest gazelle]

We have many items in our 2d game. We have used spine to animate their characters.
Can we have these items as attachments while they are not inside spine as sprite atlas and add them in runtime?
Also, if we use bones and add runtime items to specific bones, how can we specify order for them?
For example a mom hugs her baby. The baby has their own animation. Now, we want to render it between some mom sprites (hands, chest)

[meager pendant]

that doesnt help

[heady iris]

consider reading the visual scripting documentation

[rigid island]

how does it not, you're asking a VS question and thats where it goes

[heady iris]

assuming you're actually trying to use visual scripting

[rigid island]

https://docs.unity3d.com/Packages/com.unity.visualscripting@1.9/manual/vs-variables.html
RTFM - read the fucking manual next time

[spring creek]

What is "this" if not visual scripting? There is basically no information on what you're even trying to do

How could anyone help with that?

[topaz galleon]

anyone please help me, i am having an issue where the player manager spawns on scene 0 even before an scene has been loaded, like when i start laoding a scene the playermanager spawns already and then spawns the player

[upper pilot]

    [SerializeField] public Sprite CharacterSprite;
    [SerializeField] public RuntimeAnimatorController IdleAnimation;
    [SerializeField] public RuntimeAnimatorController AttackAnimation;

Is that a correct way of setting up CharacterSO animation/sprite?

[heady iris]

there's no need for [SerializeField] on a public field, mind you

[upper pilot]

doing it for consistency 😄

I will take that as a yes 😛

[rigid island]

why are they public in the first place

I generally avoid public

SerializeField if you need inspector and do a prop

[SerializeField] private Sprite characterSprite; public Sprite CharacterSprite => characterSprite;

[heady iris]

this looks like a data container

I often just use fields in that case

all those methods calls have to add up eventually

[timid depot]

hey, I want to create hinge joint on runtime, I even printed all values to 100% recreate it

void Start() {
    // print all HingeJoint properties
    HingeJoint hinge = GetComponent<HingeJoint>();
    print("HingeJoint: " + hinge);
    print("HingeJoint.anchor: " + hinge.anchor);
    print("HingeJoint.axis: " + hinge.axis);
    print("HingeJoint.connectedBody: " + hinge.connectedBody);
    print("HingeJoint.connectedAnchor: " + hinge.connectedAnchor);
    print("HingeJoint.autoConfigureConnectedAnchor: " + hinge.autoConfigureConnectedAnchor);
    print("HingeJoint.useLimits: " + hinge.useLimits);
    print("HingeJoint.limits: " + hinge.limits);
    print("HingeJoint.useSpring: " + hinge.useSpring);
    print("HingeJoint.spring: " + hinge.spring);
    print("HingeJoint.useMotor: " + hinge.useMotor);
    print("HingeJoint.motor: " + hinge.motor);
}```

```cs
HingeJoint hinge = part.gameObject.AddComponent<HingeJoint>();
hinge.anchor = Vector3.zero;
hinge.axis = Vector3.up;
hinge.connectedBody = gameObject.GetComponent<Rigidbody>();
hinge.connectedAnchor = new Vector3(2.12f, -0.06f, -1.94f);
hinge.autoConfigureConnectedAnchor = true;
hinge.useLimits = true;
JointLimits limits = hinge.limits;
limits.min = part.hidgeJoint.min;
limits.max = part.hidgeJoint.max;
hinge.limits = limits;
hinge.useSpring = false;
hinge.useMotor = false;

https://cdn.discordapp.com/attachments/763495187787677697/1206950800216301578/2024-02-08_18-33-12.mp4?ex=65dddf86&is=65cb6a86&hm=4228f2e7ab2119b39c62fd5de4a8c04d4d04780bb7c1d5124f0eddaf807e3061&
but it doesnt work at all, when hinge joint is added from editor window it works, but from script its buggy a lot

does anyone have any idea why it behaves different when created from script?

anyone? sorry for asking again and again but I really need that and can't fix that for 6 days

🙏🙏🙏

[steady moat]

Use a prefab ?

[topaz galleon]

what if the prefab for whatever reason get moved or deleted?

id take that as an inaficient way

[timid depot]

thats a good idea

can I somehow make prefab of component?

[steady moat]

That is not really an issue...

[steady moat]

No.

[timid depot]

or for example make door prefab and copy component from prefab

[steady moat]

Just make an a whole prefab

[timid depot]

it wont work for me

it would require rewriting whole car parts code

[steady moat]

If it is what it takes

[timid depot]

why cant I copy component from prefab

I dont get it

[upper pilot]

That wasnt my question, I was just asking if I used correct types for storing sprite animation or if there is a better way to do that.

[dense estuary]

Hi, currently I am struggling with my slopes, my character was bouncing and to fix that I rotated the movement to go along the normal of the slope. I think I may be applying the rotation wrong, because when logging the rotation value on slopes, it's always a decimal, so I am losing speed when going down slopes. Here is the function:

[rigid island]

I guess? there is no context here

[dense estuary]

I tried using ProjectOnPlane, but it does the exact same thing.

[hexed pecan]

Yeah as I said before, your FromToRotation does exactly what ProjectOnPlane would

While keeping the magnitude

[hexed pecan]

Why are you only returning the adjustedvel when Y is negative? Is it because you only had problems downhill?

And where does hit come from?

[rigid island]

negative implies going downslope instead of Up

[dense estuary]

Because I can go up slopes just fine

[hexed pecan]

Without this code, does it go down in a stair-like movement?

Forward, down, forward, down

[dense estuary]

Yes

He looks like he is hopping down the slope

[hexed pecan]

How are you checking ground?

That's probably relevant here

[dense estuary]

hit comes from the ground check, using a sphere cast

[hexed pecan]

Did you make sure that the spherecast hits downward slopes too?

Like does it extend downwards at all

[dense estuary]

Yes

[rigid island]

im actually doing the same in this vid
https://youtu.be/cEQdjYk51KQ?t=735

but yes Raycast for slope is diff from grounding ( this is important)

[dense estuary]

So I shouldnt use the ground check for slopes?

[rigid island]

nope

[dense estuary]

Okay, I'll be sure to change that once I get to my PC.

[hexed pecan]

I would use a spherecast that starts from the center of the player, casting downwards and maybe a bit forwards towards the movement direction

If a spherecast overlaps with the ground at its initial position, it will not detect it

So it's important to make sure it starts high enough

[tacit solar]

hi! im looking for a way to get the angle between objects velocity and a plane when they collide

[rigid island]

Vector2/3.Angle

or SignedAngle

[hexed pecan]

So the red here is the spherecast, yellow is the hit.normal that you want

Let's just pretend that the green is a capsule

Sphere doesn't have to start that high, I exaggerated a bit

[tacit solar]

but how do i get the vector of the plane?

[rigid island]

the normal

[hexed pecan]

collision.normal/hit.normal

[tacit solar]

alr ill try it out

am i missing something?

[spring creek]

That is a collider

Not a collision

OnCollisionEnter passes a collision

[rigid island]

https://docs.unity3d.com/Manual/class-PhysicsManager.html
You could potentially get
Contact Pairs Mode to Enable All Contact Pairs
nvm this is for 3D

triggers arent exactly the same as collisions

[timid depot]

ok thanks a lot!

[dense estuary]

Oh, the other issue is that the normal thst the ground check gets is at changed angle?

[hexed pecan]

Not sure what you mean

Is that a question?

[tacit solar]

so i need to use contact points, right?

[hexed pecan]

Yeah

[rigid island]

triggers dont have contact points

You can do GetClosestPoint iirc though

[hexed pecan]

I though you have a solid collider

[hexed pecan]

Does the other collider need to be a trigger?

[tacit solar]

im not sure tbh, i was getting some collision detection problems so i just changed it to a trigger

[dense estuary]

Sorry, I was asking if the other problem is that the hit.point is determined by where on the spherecast is hit. I thought the hit.normal was just the normal of the object hit.

[tacit solar]

im pretty sure its moving to fast to get detected

[rigid island]

switch rigidbody detection mode to Continuous

also put NeverSleep

[hexed pecan]

Yeah it's the normal direction at the hit point of the spherecast.
An object doesn't just have one normal

[hexed pecan]

Switch back to non trigger then

[dense estuary]

How can I get the direction down that I need to shoot the cast to get the correct normal

Cause I get shooting it slightly ahead of the player's feet, how do I know how far?

[hexed pecan]

Well, you could just use Vector3.down
But I like to add a bit of your current horizontal direction to that

[hexed pecan]

A bit further than the bottom of your character. Maybe 0.5

[tacit solar]

what if i dont have a rb on this object?

[hexed pecan]

But I can't give you any accurate numbers, you gotta try yourself

[tacit solar]

its attached to the parent

[hexed pecan]

@dense estuary So the distance from the sphere start to the bottom of the character, PLUS some value like 0.25 - 0.5

[rigid island]

wdym u dont have a rigidbody

you just said you had a rigidbody

[tacit solar]

rigidbody is on the parent object

[rigid island]

the parent of what?

[hexed pecan]

@dense estuary Just as an examplecs float sphereStartHeight = 0.5f; Vector3 sphereCastOrigin = transform.position + Vector3.up * sphereStartHeight; float sphereCastDistance = sphereStartHeight + 0.25f;
Does that make sense?

[rigid island]

how's that relevant to changing the collision detection mode

[tacit solar]

of object with a collider

[rigid island]

huh why is the collider on the child

[tacit solar]

because i have multiple colliders

ok give me a sec ill try to explain

[rigid island]

so did you change the rigidbody collision detection mode first?

to see if work

[dense estuary]

Yeah, I get it. I'll be sure to apply that as well.

[tacit solar]

basically im trying to make a spear that sticks into walls.
when the collider on the tip collides with a surface i simply freeze rb position.

but i ran into a problem: when spear was moving fast collision detection seemed to be kinda janky

like that

so i had to change the collider to a trigger box

hope that makes any sense

[tacit solar]

yeah ive tried setting it to continuous already

sooo i should put rb on my walls?

[spring creek]

The collision messages are sent to both objects involved. So if one senses it, both will trigger

[heady iris]

Simpler colliders tend to be more reliable, yeah

[tacit solar]

doesnt seem to fix it sadly :(

what about interpolate?

[heady iris]

Interpolation is a visual thing.

[tacit solar]

oh, ok

[heady iris]

that doesn't match my understanding. using sweep-based collision detection on an unmoving object is pointless

[hollow isle]

I have this textmesh text on my gun which uses a world space canvas and for some reason instead of staying in place, it moves up and down when I move the camera up and down. Any suggestions?

[heady iris]

I bet it's non-uniformly scaled

If a child's parent has a non uniform scale, like [1, 5, 1], then it'll get skewed as it rotates

Can you show me the hierarchy while the game is running?

Have the text selected.

[hollow isle]

like this?

[heady iris]

Precisely. Check each parent up to the root. Do any of them have a non-uniform scale?

[0.05, 0.05, 0.05] is fine

[hollow isle]

one moment

Everything uniformly scaled

in the scene view it's attatched to the gun properly

[timid depot]

how can I with script copy one component to another gameobject?

in runtime

[hexed pecan]

Components can't really be moved/copied to another object

You could instantiate a prefab that has that component, though

And add it as a child

[heady iris]

Ah, I see that you have two cameras

Do their settings match, and are they moving together?

[hexed pecan]

@timid depot Or you can add a fresh component with AddComponent and copy values to it manually

[heady iris]

they're having problems with hinge joints, apparently

[timid depot]

ill check that but im not sure if it work

beacuse objects like vector3 will just copy references

need to copy each value separately

[tacit solar]

could this be caused by some delay of OnCollissionEnter2D?

[hollow isle]

yeah I believe they're moving together and their settings match.

I think I know what the problem is though

[tacit solar]

like does it trigger the same frame as the collision happens?

[hollow isle]

the UI camera only sees ui, but the gun is parented to the other camera

[tacit solar]

cuz im pretty sure i can see it bounce off for a split second before freezing in place

[hexed pecan]

Yes, at the end of that physics frame

How exactly is it wrong currently?

Does it seem to stick too early?

[hexed pecan]

Because I see a gap here

[tacit solar]

yeah a gap like this

but again i can see it hitting the wall and then bouncing back

for a frame maybe

[hexed pecan]

Ah, seems like it does collision depenetration for one extra frame

I think a good workaround would be to store the spear's velocity in a variable each FixedUpdate

Then after freezing the rigidbody, move the spear by that velocity * Time.fixedDeltaTime

I think that's how I did it

[tacit solar]

sounds like it might work

ill make sure to try it

thank you!

[timid depot]

still same issue even when Im creating hinge joint same as from prefab

i have no idea at all how to do this

is this even possible to create hingejoint between 2 rigid bodies in runtime?

[tacit solar]

damn that might be too much 🫣

[hexed pecan]

Yeah, maybe move it forward only by the length of the tip?

velocity.normalized * tipLength

Or something

[timid depot]

I made it use prefab, same issue

Im losing all hopes im starting to think its not possible to create hidge joint between 2 rigidbodies in runtime

[hexed pecan]

Try disabling the collider(s) on the door when you attach it

To see if it's just colliding with near parts

[hexed pecan]

It is possible, just tricky

I usually use ConfigurableJoint though, as it gives full control

But Hinge might be sufficient here

[timid depot]

whats configurablejoint?

I can make door with it too?

[hexed pecan]

It's a joint that can do anything that the other joints can

It exposes all settings to you

[hexed pecan]

Try this though, as a debugging step ^

[timid depot]

yeah now car doesnt jitter

hmm interesting

[hexed pecan]

Okay, next you can try adding a test script with OnCollisionEnter on the door

And have it Debug.Log what it collides with

collider.name

[timid depot]

100% chassis thats sure

but whats the difference in collision when I attach it before game start and on runtime?

im making it child

[hexed pecan]

Oh. That's probably the issue

You shouldn't make a rigidbody a child of another rigidbody

[timid depot]

but when I do it before game starts, it works

[hexed pecan]

Yeah I don't know why that is.

[timid depot]

i will debug one thing wait

[hexed pecan]

Just dont ignore this ^

It can lead into unexpected behaviour

[timid depot]

im not ignoring just checking if its the case

[hexed pecan]

Hmm, I always wondered why creating a Ragdoll with the builtin tool works fine with child rigidbodies.
Maybe it's related to this, since the ragdoll is created before playing

There's some oddity in it for sure

[timid depot]

its not the reason

I moved it far away from chassis so it wont collide with anything

and its still broken

[chrome summit]

Hi, quick question. I am using TMP text MaxVisableCharacters to display a string like an old console, and am using linked overflow to split the string into 2 TMP text objects. Is there a way to get the string length of each individual part of the split string? When I do text.length, they both just display the length of the entire string.

[hexed pecan]

And is it still a child of the other rigidbody?

[timid depot]

no

wait ill record

take a look

god bot blocked video

stupid ai times

look now world is parent but its still buggy

i think that might be very hardcoded unity bug

[hexed pecan]

You should paste your code btw.

[timid depot]

only thing I can imagine now is create attached door with hinge joint and just hide/show it when needed

if (name == "LeftDoor")
{
    // set parent to parent of parent
    leftDoor.transform.parent = leftDoor.transform.parent.parent;
}```

I dont really know what to paste its like 500 lines of parts code

// if hinge joint attach to parent
if (part.hidgeJoint != null)
{
    HingeJoint hinge = part.gameObject.AddComponent<HingeJoint>();
    hinge.anchor = new Vector3(4.12f, -0.06f, -1.94f);
    hinge.axis = Vector3.up;
    hinge.connectedBody = gameObject.GetComponent<Rigidbody>();
    hinge.connectedAnchor = Vector3.zero;
    hinge.autoConfigureConnectedAnchor = true;
    hinge.useLimits = true;
    JointLimits limits = hinge.limits;
    limits.min = part.hidgeJoint.min;
    limits.max = part.hidgeJoint.max;
    hinge.limits = limits;
    hinge.useSpring = false;
    hinge.useMotor = false;

    // print all HingeJoint properties
}```

debug creating hinge joint

[timid depot]

did you try to make configurable joint in runtime between two rigid bodies before?

maybe I'll give it a try later

[hexed pecan]

Yeah, but you might run to the same issue

It's hard for me to figure out what is causing it currently

[timid depot]

i think one reason is collision with parent/other rigidbody

before game start it's getting disabled automatically

and second reason is weird positioning that makes it spin

[hexed pecan]

So if you disable the door's collider, it works fine?

[timid depot]

I can't disable doors colliderb

[hexed pecan]

What did you do here then?

[timid depot]

joint requires rigidbody and when I remove collision I can't use it at all

I mean I can but not really for game use

[hexed pecan]

I said "disable collider" not "remove collision"

[timid depot]

I need working physical door not ghost door

[hexed pecan]

Look I get that, but we are debugging here

[timid depot]

I don't have collision as component

children boxes

[hexed pecan]

So the door has children that have colliders?

[timid depot]

yes

[hexed pecan]

So disable those

[timid depot]

that's what I did herr

and it didn't spin car

[hexed pecan]

So what can we assume from that?

The child colliders are colliding with the chassis.

[timid depot]

no not really

I tried few days ago with mesh collider without children but it's the same

[hexed pecan]

Then the mesh collider was colliding with the chassis, lol

[timid depot]

so what can I do

I need collision

I don't need ghost door

[hexed pecan]

Again, stop saying that, I know that

You could call Physics.IgnoreCollision manually for each collider in the door and each collider in the chassis

[timid depot]

I have option for that in my parts system

I'll try tommorow and let you know if it worked

[hexed pecan]

Alright

[timid depot]

but wait

[timid depot]

what about this spinning problem

because collision is one problem

and this spinning thing is bigger problem

[dense estuary]

Um, by the way, I dont know if this would work, since I just debugged the angle or the normal and its perfectly perpendicular.

My issue is that the quaternion, which I am multiplying by, is a decimal in every place. This is the quaternion from the last screenshot

[hexed pecan]

That is how quaternions look

And the normal in your screenshot looks, well, normal

Multiplying a vector with a quaternion will rotate that vector

So I dont see any issues here

[dense estuary]

I still can't figure out why its slowing me down. I did what navarone said, and I'm not sure if I need to do what you said because the normal is correct.

[heady iris]

If you want something more intuitive, log the eulerAngles from the quaternion

[dense estuary]

Alright

[hexed pecan]

Honestly a video of the issue could help

[dense estuary]

One sec

Here is my whole script just incase: https://hastebin.com/share/icumebuyur.csharp. And here is the video: https://streamable.com/extgfb

I also noticed another bug while recording this. if I jump while on a slope and land back on it, it sends me flying in the direction that the slope is going down towards.

[hexed pecan]

You are still raycasting from transform.position instead of a bit above

[hexed pecan]

I can't see the problem in the first part. Are you moving slower downhill?

[dense estuary]

Yes

[rapid stump]

Sorry this isn't a coding question/problem, and I couldn't find a channel that matches what this problem is
I did 2 hours of work, forgot to save and when I tried entering play mode, it's loading indefinitely. If I Alt+F4/task manage kill task I'll lose all my progress. What do I do XD

[somber nacelle]

you probably have an infinite loop in your code so it probably is actually code related. but you'll have to force close unity

don't open it immediately after force closing it, you can recover the scene backup (which you can google how to do). but once unity opens that backup is gone

[lean sail]

Your code saves regardless because it is unrelated to unity. A temporary scene should be made when you run play mode, so you havent lost all your progress.

[rapid stump]

I thought that initially. But in the past I changed something small, had the same infinite loop and when I force closed, and reopened Unity the changes I made were undone.

[rapid stump]

Thank you

[lean sail]

As boxfriend said, the scene backup is gone when you open unity up. The code is 100% unrelated to unity though

[odd arrow]

is there any proper way to create a font or text renderer using just textures?

i have a bunch of textures for each character with their respective char code but there doesn't seem to be any nice way to create a font from them using tmp and default unity stuff

[quaint rock]

define proper, bitmap based text rendering has been a thing games have done for a long long time

[odd arrow]

proper as in not scuffed?

[quaint rock]

though you tend to be forced into mono spaced looking things and have no kerning

[odd arrow]

nah i have the data necessary for each character and their correct widths n all that

[quaint rock]

also scuffed is not much to go on

really you prolly just want to turn of compression and texture filtering

it can really only look good for blocky pixel art type characters

[ashen yoke]

is there any way to convert bitmap fonts to ttf ?

i would try to convert it in the os, then feed the result to tmp

[quaint rock]

since without the SDF based fonts tmp generates from regular fonts things do not remain crisp at all sizes

and you missing out on features like outline and shadows

[odd arrow]

for my case that's unnecessary tho, everything is already styled as needed in each glyph

[odd arrow]

tis worth a shot

[ashen yoke]

there are some tools like that https://github.com/benob/png_font_to_ttf

[quaint rock]

https://forum.unity.com/threads/creating-a-pixel-font-from-a-bitmap-image.1260656/

[ashen yoke]

seemingly they just api call fontforge

[odd arrow]

yeah was looking at this

unfortunately i dont have a spritesheet and there's like 1000+ characters for this font style so i dont know if combining it into one would be the best

im starting to think it might just be better to write my own text renderer to fit this case lol

[ashen yoke]

that may take a little while

[dense estuary]

Yes that is my problem. When aligning the movement to the slope, the velocity magnitude decreases.

[heady iris]

Remember the original velocity. Normalize the slope-corrected vector, then multiply it by the original velocity

This will malfunction if you're on a 90-degree slope

actually, will it? I guess you'll be falling at that point anyway..

[dense estuary]

Like this? ```cs
Vector3 SlopeVelocityChange(Vector3 vel)
{
if (Physics.Raycast(transform.position, Vector3.down, out slopeHit, 1.5f, ~LayerMask.GetMask("Player")))
{
var currentVel = vel;
var rotation = Quaternion.FromToRotation(Vector3.up, slopeHit.normal);
var rotatedVel = rotation * currentVel;
var adjustVel = rotatedVel.normalized * currentVel.magnitude;

    if (adjustVel.y < 0)
    {
        return adjustVel;
    }
}
return vel;

}```

[heady iris]

oh, you're rotating the vector, not projecting it onto a plane

I don't see any reason for the velocity to go down on slopes if you rotate the vector.

[dense estuary]

It essentially does the same thing as projecting on the slope

[heady iris]

Projecting onto a plane reduces the magnitude of the vector. Rotating it doesn't.

[dense estuary]

Um, but it still is, so I just kinda assumed that they are practically the same thing

[heady iris]

Log the magnitude of the rotated vector and see if it differs from the original magnitude.

It should not.

[dense estuary]

It does. When going up a slope the magnitude of the velocity sits around 10, while going down decreases more depending on how steep the slope is.

[heady iris]

I'm talking about the magnitude of rotatedVel, not whatever your velocity winds up being at the very end.
