well, thanks a lot :3

btw this is a good way to reflect it, right?

    public void Parry()
    {
        Debug.Log("PARRY");
        rb.linearVelocity = -rb.linearVelocity;
        transform.right = rb.linearVelocity.normalized;
        parried = true;

    }```i know that "if it works, it works", but something feels...off

unless is ok, then im just paranoid

[rich adder]

its fine if all ur doing is reversing direction

mine is 3D and reflect in the direction you aim at

[sand mesa]

alright

[sand mesa]

i wanna do something stupid; i wanna control where it is in the scene the players spawn

[rich adder]

pretty vague

[rocky canyon]

use an empty gameobject

"SpawnPosition"

instantiate(prefab, SpawnPosition.position, Quaternion....)

public class Typewriter : MonoBehaviour
{
    public bool canmove;
    public string dia;
    [SerializeField] TMP_Text d;

    public IEnumerator Speak(string[] wsaid)
    {
        canmove = false;
        d.text = "";
        for (int e = 0; e < wsaid.Length + 1; e++)
        {
            d.text = "";
            for (int i = 0; i < wsaid[e].Length; i++)
            {
                d.text = d.text + wsaid[e][i];
                yield return new WaitForSeconds(0.05f);
            }
            yield return new WaitUntil(() => Input.GetKeyDown(KeyCode.Z));
            if(e == wsaid.Length)
            {
                yield return new WaitUntil(() => Input.GetKeyDown(KeyCode.Z));
                canmove = true;
            }
        }
    }
}
``` is this a good typewriter effect or should i make changes

[rich adder]

if its working how you want then its fine

would probably opt for not using magic numers

yield return new WaitForSeconds(0.05f);
yield return new WaitForSeconds(timeBetweenChar);

[slender nymph]

rather than allocating a new string each iteration of the loop, you should instead assign the entire string to the TMP_Text object then just modify the maxVisibleCharacters property

[nocturne hemlock]

Thank you

just want it to be optimized :)

[nocturne hemlock]

ty too didnt even notice

i was locked in for a sec lmao

[rich adder]

when TMP is not an option, can also use StringBuilder iirc much better than new string

[slender nymph]

string builder wouldn't really make much difference in this scenario because it would still need to allocate a new string to display for each iteration of the loop

[rich adder]

yea just meant in general

[slender nymph]

another optimization to think about would be to cache the WaitForSeconds and just reuse the same instance of that instead of creating a new instance each iteration

[rich adder]

oh yeah this def ^

if the number is not changing you just cache

var waitTime = new WaitForSeconds(timeBetweenChars); //before loop

yield return waitTime; //inside loop

[nocturne hemlock]

okay i see how it works ty so much

im learning

[rich adder]

[rocky canyon]

pro-gamer move

yield return oneSecondWait

[cosmic dagger]

Exactly; the only way to do it . . .

[rich adder]

nested while loops is the way XD

I hardly find myself using any Yield Instruction anymore

[sand mesa]

quesiton; how can I arrange it so
DontDestroyOnLoad();
refers to itself

[eternal star]

Hi, I think my Unity file is corrupted, and I'm getting a "BuildProfileContext" error. How can I create a new project and transfer my files?

[naive pawn]

what do you mean by "refers to itself"?

[sand mesa]

the gameobject holding the script itself won't be destroyed on load

[naive pawn]

DontDestroyOnLoad(this) or DontDestroyOnLoad(gameObject)

[rich adder]

gameObject

[sand mesa]

roger roger

[rich adder]

basically
gameObject is the entire object
this is the script/component

in DDOL that means the whole object anyway

[eternal star]

Can you also help with backups? How do you create backups?

[rich adder]

https://youtu.be/5IxUElilf2M?si=AhkBbEou3EebJJOY

[rocky canyon]

either use Version Control, or duplicate and zip for local backups

[ruby zephyr]

Do you guys think it's good to make small games like flappy bird with chat gpt and make them explain how the code worked code by code? I'll ask for very deep explanations then I'll also deeply comprehend it.

[rich adder]

no

[polar acorn]

You should instead use the wealth of actual knowledge on the subject from human beings with the ability to fact check, rather than the over-engineered markov chain that predicts the next word in the sentence really fast

[rich adder]

"deep explanations" is useless if its just telling you some hallucinated bullshit

and you as a beginner wont know when its hallucinating

its also not guarateed you get suggested the best method / less cumbersome or efficent way to do something

[ruby zephyr]

Okay, I'm afraid I don't have the developer mindset that every youtuber is talking about yet.

So.. Do you guys then know the most effective way of learning?

[rich adder]

!learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[rich adder]

what youtuber ? why are you listening to youtubers

[ruby zephyr]

As I think I am stuck in a tutorial trap where I have already watched a hundred tutorials about programming and unity yet I don't know what they are for.

[rich adder]

there is a difference between incrementing your knowledge step by step only moving onto the next thing when you actually know how to use what you learned, and just following / copying

[ruby zephyr]

Tutorials and tips Like

• Be motivated
• Don't Copy Codes
• Copy it your own way
• Make small games
• Participate Game Jams

And more

[rich adder]

sure. more or less.

motivation to me comes with pursuing new knowledge / learning new thing

you ideally copy code once you understand what each line does

even just learning small bits, you dont have to "make a small game" in the beginning.
even just doing simple C# learning through console apps will help you understand basic coding concepts

personally after a while it was easier to just learn C# without slapping all those unity APIs/concepts in

Unity is an API so once you learn C# on its own, you can read any APIs aside from unity.. the rest is just knowing the engine specific quirks like GameObject concepts etc

[ruby zephyr]

well I'm mostly familliar with unity's tools now since it is the first thing that I tried learning.

Should I then watch simple c# tutorials that focuses with unity?

[rich adder]

aside from Unity Learn most of the Unity C# tutorials are complete dumpster fires

In a regular .NET /C# enviroement you're more likely to get better material

(aside from learn) unity tutorials are made for content views not accuracy

[ruby zephyr]

May I only focus on Unity programming for now?

And not about web dev and more

[rich adder]

what exactly do you mean with "Unity programming"

[rich adder]

no. Im talking about the normal C# learning

creating objects, methods, properties, arrays

etc

You are less likely to learn all these in Unity tutorials

they assume you somewhat have that knowledge already

[ruby zephyr]

Do I do hands on learning?

[rich adder]

idk what u mean by"hands on learning"

https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/tutorials/
or
https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/tutorials/hello-world?source=recommendations

[ruby zephyr]

Oh okayy sorry, btw we had a long conversation already soo.. To summarize, What should I do?

[rich adder]

do a bit of both

learning regular c# on its own, apply those concepts in unity then slowly start using unity specific methods / components

https://learn.unity.com/project/beginner-gameplay-scripting
this is good too it hammers the point of C# in unity context

[ruby zephyr]

Alright thats nicee, thanks very muchhh 🤗

[pure drift]

https://paste.ofcode.org/bQLwbfjMzMy3UamuUYG38p does anybody know why my code doesnt detect the center of the screen i have a tag named center but it doesnt seem to detect from this script

[polar acorn]

Try putting a log before the if and log the tag of the object you hit

[pure drift]

ok i will try that rq

[hollow gyro]

Is there a "best" way to start? or at least a preferred route?

[rich adder]

previous convo starts here
#💻┃code-beginner message

mostly where the links are

in a nutshel Unity learn site and Microsoft's website

[pure drift]

so i put the name of the gameobject it hit and it shows enemies but never the target gameobject

[hollow gyro]

I see well thank you

[polar acorn]

The Three Commandments of OnCollisionEnter2D:

1. Thou Shalt have a 2D Collider on each object
2. Thou Shalt not tick isTrigger on either of them
3. Thou Shalt be moving via a 2D Rigidbody on at least one of them

[rich adder]

where and what did you even log?

show new code

[naive pawn]

dynamic 2d rigidbody

[pure drift]

yep i made sure to do that

[polar acorn]

If it's not dynamic you couldn't be moving via rigidbody

[rich adder]

kinematic can still call OnCollision if the other object has dynmaic rb

[polar acorn]

Right, hence the "At least one of them"

[rich adder]

oh was replying to original Chris message they edited

[naive pawn]

yeah, at least one has to be a dynamic rb

[pure drift]

so on the object that is moving i should have a dynamic rigid body?

[polar acorn]

You need to be moving it with a dynamic rigidbody. If you're moving it by changing it's transform position it won't work

[naive pawn]

i mean, MovePosition exists.

[polar acorn]

You have to actually be using the rigibody to handle the movement

[rich adder]

weird..fun fact Physics2D kinematic has velocity 🤔

[naive pawn]

why wouldn't it

it's the same component

[rich adder]

Rigidbody 3D doesnt have velocity once its kinematic

it just gets reset to 0

in 2D doesnt work like that, it screwed me over a couple of times

[naive pawn]

huh

[rich adder]

thats why they have the "Static" flag

[pure drift]

does that mean i cant move my character like this https://paste.ofcode.org/sDXqh9eVQXi8t46uSyyrsq

[rich adder]

not at all

this is essentially teleporting

the dynamic rigidbody has to play "Catch up" every physics tic.. not good

[polar acorn]

Correct. You'd need to actually move with the rigidbody

[rich adder]

Rigidbody is living inside a different scene, when you omit moving the rigidbody the regular scene moves the transform while the physics is ignored

when you move rigidbody, the opposite happens. The rigidbody moves the Transform

[pure drift]

any tips for applying seek using rigid body

[rich adder]

applying seek?

[pure drift]

seek steering behavior

[rich adder]

most of the time you can just replace it 1-1

transform.position += (Vector3)(velocity * Time.deltaTime);
with
rigidbody.velocity += velocity

[pure drift]

intresting thank you

[covert flower]

so I have an issue that i was trying to fix where I would ragdoll an enemy and they would then reset to the position the started the scene in. I attempted to fix it with the code at the bottom however this made it worse. any reccomended fixes

if health is 0 or less

what are you trying to Reset the positions/rotations of ragdoll you mean?

[covert flower]

nah it doesnt ik its not the best optimized

[covert flower]

basically just want them to get back up where the ragdoll finishes

[rich adder]

doesnt enabling Animator already do that?

[covert flower]

nah for some reason they spawn on the parent

or where the ragdoll started instead of ended

[rich adder]

can you make a quick video of issue? having a hard understanding whats what since Idk the hierarchy
this looks hella sketch
Transform parentTransform = GameObject.Find("EnemyVis").transform;
Transform specificChildTransform = parentTransform.Find("mixamorig:Hips");

[prime cobalt]

How can I find out which of these values is creating an index out of bounds? I can't debug.log any of the values besides the kernel ID because the error makes the script not work after this line and this script doesn't get the values until this line. And compute shaders can't use debug.log.

[rich adder]

breakpoints in debugger?

[wintry quarry]

the rest of the parameters are out params, so wouldn't the kernel ID be the only relevant one?

You probably don't h ave a kernel with that name?

Unless the index out of bounds is happening elsewhere

What's the actual error message say?

[prime cobalt]

I can print out that one by just debug.logging the find kernel function and its ID is zero.

[wintry quarry]

invalid kernel index seems pretty clear

[rich adder]

doesnt FindKerner return a string?

hows a string get in an index wanted in GetKernelThreadGroupSizes

[wintry quarry]

no it returns a kernel index

[prime cobalt]

It returns an int

[rich adder]

ahh yea myb my eyes are broken

[wintry quarry]

Can you show your shader?

[prime cobalt]

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

[rich adder]

make it mp4

[prime cobalt]

It returns a zero which is less than 3 and not negative so it shouldn't be the index's fault... I think...

[wintry quarry]

it's weird to me it's returning 0 if CSMain is not the first one defined. But maybe it uses the pragma order?

[prime cobalt]

I mixed around the pragma order and yeah it shows 1 in the console now.

[wintry quarry]

and still has the same error?

[prime cobalt]

Yes

[wintry quarry]

but with 1 this time?

[prime cobalt]

Yep

[rich adder]

have you seen this before
https://www.youtube.com/watch?v=KuMe6Iz8pFI&list=PLx7AKmQhxJFaZXE1c0wqc35l4kau-WCNA&ab_channel=KetraGames

[wintry quarry]

Ok from what I'm reading it means you have a syntax error in your shader somewhere

bascically it's not compiling properly

so there is no kernel

[prime cobalt]

Hmm ok, good to know. Thanks

[covert flower]

ty ill look at this

[wintry quarry]

I think if you look at the shader inspector you may see the compile error

[covert flower]

looks like itll fit perfectly

[rich adder]

yeah tbh what You got seems a bit more code than it normally is lol

for me once I disable animator the ragdoll falls, i just use a method to iterate through all rigidbodies limbs to set them back to active/gravity

[prime cobalt]

I can't believe I didn't think to look in the compute shader itself for compiler errors... I may be stupid.

[inland cobalt]

private void Rotate()
{
    Vector2 mouseDelta = _actions["LookDelta"].ReadValue<Vector2>();
    float rollDirection = 0f;
    if(_actions["Roll Left"].IsPressed()) rollDirection ++;
    if(_actions["Roll Right"].IsPressed()) rollDirection --;

    float multiplier = Time.deltaTime * _sensitivity * 5f;

    Quaternion yaw = Quaternion.AngleAxis(mouseDelta.x * multiplier, Vector3.up);
    Quaternion pitch = Quaternion.AngleAxis(-mouseDelta.y * multiplier, Vector3.right);    
    Quaternion roll = Quaternion.AngleAxis(rollDirection * Time.deltaTime * _sensitivity * 10f, Vector3.forward);      

    transform.localRotation *= yaw * pitch * roll;
}```

Anyone know why my looking around feels jittery with a mouse, and straight up doesn't work with trackpad? I can't seem to figure it out

(Rotate is called every update)

look delta is this

[rich adder]

not sure its related but you should never multiply mouse by Time.deltaTime

[swift crag]

That's causing it, yes

[rich adder]

delta already returns the distance between frames

[swift crag]

If a frame takes longer to render, you'll get more mouse movement

[inland cobalt]

ah i get what you mean, cheers

[swift crag]

and then you'll multiply that larger value by another larger value (since deltaTime is larger than usual)

thus, jitter

Also, rollDirection++ is going to be framerate dependent

You need to factor in deltaTime there

It doesn't matter that you multiply it with deltaTime when computing how much to roll by

You're going to change rollDirection at a framerate-dependent rate

[inland cobalt]

i get what you mean now, I overlooked the fact that delta is already framerate independent, thanks

yeah that's a whole lot smoother

[sand mesa]

alright

The best I can aritculate my pressing is "I wish to save the last position my player was in using a "DontDestroyOnLoad" object as that player leaves the scene, and then ensure that when I enter back into the scene, the player spawns at that position

[rich adder]

Vector3 myInitialPos
...
myInitialPos = transform.position

you probably use a dictionary too for each scene

either by name or index

Dictionary<string,Vector3> myPositions = new ();
string sceneName = SceneManager.GetActiveScene().name
myPositions.Add(sceneName, transform.position)
transform.position = myPositions[sceneName]

You can get the current scene name on scene switch event

[sand mesa]

working on it

[sand mesa]

alright

perfect

last thing; how do I see how many objects of the same type is in a scene?

i wanna prevent myself from making clones of instantating players

[rich adder]

int count = FindObjectsByType<T>(FindObjectsSortMode.None).Length;

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Object.FindObjectsByType.html

[sand mesa]

okay, sorry, ive just been using it to automatically assign references

[rich adder]

I think it searches all scenes open too so keep that in mind

[sand mesa]

well too damn bad

wait, HOLY THAT'S WHAT IM MISSING!

THANSK FOR THE INSPRIATION

[sand mesa]

right...

how do I make sure the code destroys the duplicates and not the original?

ive managed to save the original in its own little variable, but I am not sure how to format it

[frank rivet]

I have fixed smooth dampening but i still cannot figure out how to make the plane turn towards the direction the free cam is facing, any help or even sugguestions will be nice

[woeful carbon]

Has anyone here made the classic snake game but also tried incorporating rotation or curved sprites to show the snake turning cause I’m trying to do that and struggling to find a good way to go about it

[drifting cosmos]

just make a curved sprite

[rich adder]

duplicates of what? wdym?

[sand mesa]

of the player

[woeful carbon]

And it just generates the curved sprite instead of the square?

[rich adder]

you're not porting the same player?

DDOL ?

[sand mesa]

... no...

i just leave the player object open....

[drifting cosmos]

instead of the square?

[rich adder]

wdym leave the player object open?

[sand mesa]

i made a persistent variable within the scene that records the instance of the player pawn

then the "player" leaves for the next scene, and when I swing back, it spawns a new player instead of using the old one

[woeful carbon]

Well yeah rn every time you eat the food it places a square sprite behind the head, are you just saying to just use a circle instead

[sand mesa]

and it can keep going for as long as it takes

[drifting cosmos]

make 2 sides a circle and 2 sides a square

[rich adder]

whats the need to spawn a new player each time?

[sand mesa]

modularity...

[rich adder]

how?

[sand mesa]

I see now that it was HELLA dumb to constantly spawn the player object

... hm...

maybe I can just do without that code

one second

[rich adder]

there is no need anyway

spawning new one

[woeful carbon]

So like a half oval

[drifting cosmos]

like see the bottom left quad

[woeful carbon]

I’ll try it out tomorrow and get back to you

[drifting cosmos]

is making an object thats of a type of one of its inherited things for generics only or is there other reasons

[wintry quarry]

Can you be more specific about what you mean?

[sand mesa]

oh god

[drifting cosmos]

like you make an object of class Class_ and it inherits from interface interfac and then you make an object of Class - but with the type of interfac

[sand mesa]

the persistent level disappears as soon as I move to another level

I thought the point was it persists!

why does it go away?!

[drifting cosmos]

dont destroy on load?

[sand mesa]

an object in that scene is set to that

[wintry quarry]

Classes cannot inherit from interfaces, they can only implement interfaces.

As for assigning a value of a type to a variable of a broader type, that has nothing to do with generics

[wintry quarry]

Wdym by persistent level

[sand mesa]

this block of code is designed to ensure the level holding the instance doesnt go away

and is always lingering

except somehow it vanishes whenever I load a new level besides the one I start in

which kind of defeats the purpose of it being persisent

[drifting cosmos]

like whats the reason for making a class object of an interface it inherits is it only so you can have a class thats uses that interface like the generics <interface>

[wintry quarry]

You need to call DontDestroyOnLoad on the GameObject, not the script instance

[sand mesa]

no- right

[sand mesa]

look at the heirarchy for the level "DevRoom"

[wintry quarry]

You kinda have it backwards. You write code that can deal with the interface, and then you are able to reuse that code for any object that implements the interface

[sand mesa]

it is there once I start the game, and GONE the moment I change the level

[wintry quarry]

So you only need to write it once

[wintry quarry]

Only GameObjects in the DontDestroyOnLoad special scene will survive a non additive scene load

[sand mesa]

it is set to additive though

[wintry quarry]

Some other code is unloading the scenes then

[sand mesa]

I think I found the error

one second

[wintry quarry]

Or calling LoadScene without Additive

[sand mesa]

i kind of need it to be additive though

its got the canvas needed for fade to black and ui elements

[wintry quarry]

I didn't say not to make it additive

[sand mesa]

thats exactly what you said

[wintry quarry]

Never said that

[sand mesa]

calling Load Scene without Additive -> remove additive -> don't make it additive

[wintry quarry]

It was an extension of the thought above it:

Some other code is unloading the scenes then
Or calling LoadScene without Additive

[sour fulcrum]

from a beginner standpoint interfaces can be kinda hard to learn because a lot of their primary usecases exist in spaces outside of Unity where-as in Unity making a separate monobehaviour component usually fills those demands

[wintry quarry]

I'm listing things that could possibly be the problem

not solutions

[drifting cosmos]

im trying to figure out whats the point of making an object of like this interface class = new class

[wintry quarry]

Imagine this:

class Monster {
  int hp;

  public void TakeDamage(int dmg) {
    hp -= dmg;
  }
}

class Player {
  int hp;

  public void TakeDamage(int dmg) {
    hp -= dmg;
  }
}```
Now if I want to write code for an attack that can hit a player OR a Monster.,.. I have to do something like this:
```cs
void DamageTarget(object target) {
  if (target is Player p) p.TakeDamage(5);
  else if (target is Enemy e) e.TakeDamage(5);
}```

But with interfaces I can do this:
```cs
interface IDamageable {
  void TakeTamage(int dmg); // the interface only defines the "signature" of the method, not the actual implementation
}

class Monster : IDamageable {
  int hp;

  public void TakeDamage(int dmg) {
    hp -= dmg;
  }
}

class Player : IDamageable {
  int hp;

  public void TakeDamage(int dmg) {
    hp -= dmg;
  }
}```
And then I can write code like this:
```cs
void DamageTarget(IDamageable target) {
  target.TakeDamage(5);
}```

[wintry quarry]

There's very little point to doing precisely that and it's quite rare

[drifting cosmos]

void DamageTarget(IDamageable target) {
target.TakeDamage(5);
}
so when you write in a game object it will only work if it has Idamageable interface implemented would the takedamage have to be public if youre calling a damage target say from like a bullet object or something

[wintry quarry]

There are no GameObjects involved here

you cannot add interfaces or modify the GameObject class

only your own custom classes

it will only work if it has Idamageable interface implemented

Yes the parameter is of type IDamageable so it has to be a type that implements that interface

[sand mesa]

... right

[wintry quarry]

would the takedamage have to be public if youre calling a damage target say from like a bullet object or something
That's a totally different topic, but yes methods have to be public to be called from an outside class.

[sand mesa]

is there a way to store the last position of my player in another scene?

[wintry quarry]

Vector3 lastPlayerPosition;

scenes themselves don't store anything

you can store data on scripts that you put instances of in scenes

[sand mesa]

and that relies on the object holding the script to be constantly present, right

through instance

[wintry quarry]

If you want the data to stick around, the object holding the data has to stick around

[sand mesa]

the PROBLEM is that it constantly makes copies

whenever I load into the scene

[wintry quarry]

instance as you put it is just a convenient accessor variable.
The thing you're thinking of is DontDestroyOnLoad

[wintry quarry]

Well if you look up any Unity singleton implementation, it includes code for handling such copies.

[sand mesa]

thats not how you create instances?

[wintry quarry]

Everything in the scene is an instance

every actually instantiated object is an instance

[sand mesa]

right- instances carried over to another scene

that means "don't destroy on load" doesn't it?

[wintry quarry]

you are confusing the concept of an instance with that specific static variable we are calling instance which is part of a concept called "singletons". A singleton is a class for which we are guaranteeing there is only ONE instance in existence at a time. Therefore we can have a single static variable pointing to that instance

We typically call that variable instance because, well, it's a reference to the only instance of the class that exists.

[sand mesa]

right right right

so I have the variable created and it tracks where the player is

how, then, do I use it

[wintry quarry]

Presumably we're talking about some script that holds the player position data?

[sand mesa]

the script holding the variable gets destroyed when I load another level

[wintry quarry]

not if you use DDOL

you would have a DDOL singleton

that stores the position

then you access that singleton whenever you want the data on it

simple example:

public class MyDataHolder : MonoBehaviour {
  public static MyDataHolder Instance { get; private set; }

  public Vector3 LastPlayerPosition;

  void Awake() {
    if (Instance != null) {
      // This is a second copy. Destroy ourselves and stop the function here
      Destroy(gameObject);
      return;
    }

    // this is the first and only instance. Assign the Instance var and DDOL ourselves.
    Instance = this;
    DontDestroyOnLoad(gameObject);
  }
}

Then from any other code you can access the data with:

MyDataHolder.Instance.LastPlayerPosition```

[sand mesa]

fixed it

i goddamn hope

[final trellis]

https://pastebin.com/Fd18h2DM

the code thats causing the rror

oh wait

i just added

if (!audioSource.isPlaying)
    return;

nvm it diddnt fix it

unity error is gone, but now it still crashes

[final trellis]

same error and when same thing happens

[ivory bobcat]

Try commenting out sections to see if what's causing the crash is within this function

[final trellis]

eh i think im just gonna disable that part

its not a nessecary gamneplay feature

[sand mesa]

RIGHT

my "dont destroy on load" object is not registering in th egame itself

it appears to only work during editor playthrough

why is this the case?

[edgy tangle]

How do you mean?

How do you determine “object is not registering”?

There’s any number of problems that can come with Singletons if you’re not careful, so you need to be specific about what is going wrong and when. That said though usually the problem is a race condition of some kind.

[sand mesa]

In my editor there is an object that is persisting to carry variables across levels

But once I built the game, it's not carrying anymore

Oh for crying out loud

I have to pricking redo the - HHHHHHHHHHHAAAAAAA

[sand mesa]

Can singletons persist through scenes?

[sour fulcrum]

if the object isn't destroyed

[short gust]

I don't know to which channel this question goes, because it's about git lfs and googling doesn't help
I have Unity 6 with Adaptive light probes and their data is baked with *.bytes binary (and they grow quite huge)
Do I need to add them to lfs? And if so - with which attributes?
Sorry, if it's off-topic, but there literally no info about that I can find

[charred spoke]

If this is for github then if the file is above 100 mb you need to add it to lfs

[north kiln]

This sounds like nonsense. Prefabs don't exist outside of the editor. Are you having trouble persisting a root object in a scene? Or are you using DDOL on something else?

[edgy tangle]

I’ve never heard of this

[edgy tangle]

If they are set to DontDestroyOnLoad, then yeah they will persist across scene loads

[sand mesa]

Yeah I gave up

I just used player prefs

It's just positional data

[sour fulcrum]

I'm pretty sure your right in that the screenshot is wrong but prefabs exist in runtime in hideanddontsave no?

i guess not explicitly as prefabs but

[sour fulcrum]

pretty sure thats not intended for any actual game data, let alone data between scenes at the runtime

thats just for settings and such

[north kiln]

The runtime instance has no connection to the prefab instance, so the entire logic of making a prefab to fix a bug to do with the runtime instance is fraught

[livid grail]

Hey everyone! Ive stumbled into a very wierd bugg, it doesnt happen all the time so it is completley random...

Im using my mouse movement to open doors but somehow, sometimes my **rotation **values gets null, with is very wierd becuase it is float?

This is the error line, and the line that "rotates" the door
door.localEulerAngles = new Vector3(0, rotation, 0);

And this is how I set the rotation value

mouseValue = (Input.GetAxisRaw("Mouse X") * directionClamp ) / Time.deltaTime;
rotation = door.localEulerAngles.y;

float tempRotation = rotation + mouseValue;
rotation = Mathf.Lerp(rotation, tempRotation, Time.deltaTime);

My first guess was the mouse input value but it always returns a value, so Im currently lost

[silk night]

In which loop are you doing this?

also in this chain rotation does not seem to be the first value to be null, set a breakpoint and check up the chain what is actually null

[livid grail]

@silk night It isnt a loop, it is a regular method that only runs when the character is interacting with a door

the wierd thing is that I can play and stop the game 10 times without any error occurring, then on the 11th restart it can pop up, if I restart again it is just gone...

[silk night]

i mean update loop, fixedupdate loop? otherwise your lerp doesnt make sense

[livid grail]

Ah the method is being called from Update

[silk night]

well then its time to debug, do a null check and a log in there, then set a breakpoint on the log so you only break when its actually having an error

(or a conditional breakpoint if you IDE supports that)

[dusty geode]

door is null not the rotation

only thing that can be null on that line is door

[livid grail]

Door is not infact null, the rotation value in the inspector is set to NAN if I manually reset it to 0 it works again

it is the float value that returns NAN

debugging the rotation setup atm

[red brook]

@solar tusk

[dusty geode]

Sorry I assumed null ref exception my bad

Maybe post the error?

[solar tusk]

Yeah, so there is this other method. Like, 3D model it, animate it inside a modelling software. And then render the animations frame to PNG. Then make a sprite sheet for them, and use that sprite sheet animation in unity

@red brook

[red brook]

There are more than one way to do this

u can either do it 3D 2D or do 3D then bake it into 2D etc etc

[solar tusk]

I wanna do how Township did it. So what should I do

[red brook]

do you wana do exatly how they did it?

[solar tusk]

Yes. Or atleast want to know how did they do it exactly

[dusty geode]

Why are you dividing by delta time?

[red brook]

you will never know unless you contact them

so write an email perhaps

to them

[solar tusk]

How about that

Sure, thanks

[livid grail]

@dusty geode Before I added the delta time the mouse input value was different on every machine an not reliable, the door sensitivity was dependent on the games FPS

[dusty geode]

I'm pretty sure you should be multiplying by delta time not dividing by it if anything.

Also I don't think mouse input should be modified by delta time since it is already frame rate independent.

It comes in as the amount the mouse has moved since last frame.

Also why are you lerping at all. That lerp doesn't really make sense

You'll never reach the target

[livid grail]

Im sure there is much better ways than my lerp but before I added the lerp the door was too snappy and had no weight to it, now it "drags" like I intended it to, so for me it works fine as it is :3

I tried to remove the DeltaTime and multiple it, both methods broke the rotation and it didnt respond to any mouse movement at all

[dusty geode]

You should remove it from the line where you are multiplying mouse by it

Also I would just use Quaternion.RotateTowards or Vector3.RotateTowards

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Quaternion.RotateTowards.html

[livid grail]

Im certain this is a better way than my lerp but I dont think the lerp is what is causing the NAN error

ive placed a lot of debugg lines atm in the code but what sucks is that the error rarely occurs 🥲

[dusty geode]

From my experience reading euler angles directly from transform can lead to unexpected results

have a class member variable that represents your y and modify and read that instead

Or do what I said and don't use euler angles and use methods that don't use them. You can rotate in other ways. Like rotate around the Y axis

[livid grail]

Are you reffering to this line ?
door.localEulerAngles = new Vector3(0, rotation, 0);

[dusty geode]

No the line where you are reading the y euler angle component from the door

Just call door.Rotate with this overload
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Transform.Rotate.html#:~:text=public void Rotate(Vector3 axis%2C float angle%2C Space relativeTo %3D Space.Self)%3B

[dusty geode]

Let me know if you don't understand

@livid grail something like this

mouseValue = Input.GetAxisRaw("Mouse X");
door.Rotate(door.up, mouseValue);

Your problem really stems from reading directly from euler angles since multiple combinations of euler angles can represent the same rotation. Just because you set one combination does not mean you'll get the same combination back when reading from it. So either have a local Vector3 to represent euler angles that you have complete control over modifications or apply rotations without them

[livid grail]

Its wierd, Im not sure why but it only reacts whenever I stop dragging it however if I devided the mousevalue but delta time it worked whenever but the "smooth" movement wasnt present anymore

and yes the method is being called everyframe, I get debug logs all the time that it is being called

[dusty geode]

public float minYRotation = -45.0f;
public float maxYRotation = 45.0f;
private float currentYRotation = 0.0f;
private Quaternion initialRotation;

void Start()
{
    initialRotation = transform.localRotation;
}

void Update()
{
    float rotationSpeed = 45f;
    float rotationIncrement = rotationSpeed * Time.deltaTime;

    currentYRotation = Mathf.Clamp(currentYRotation + rotationIncrement, minYRotation, maxYRotation);

    Quaternion localRotation = Quaternion.AngleAxis(currentYRotation, Vector3.up);

    transform.localRotation = initialRotation * localRotation;
}

You should be able to adapt that code to your needs

Let me know if you have questions. You need to understand it

[dusty geode]

Dont really know what you mean here but stop applying Time.deltaTime as a factor to your mouse movement. It simply is just not correct

[livid grail]

Thanks! Yeah I can read that 🙂 Im just heading out tho but I rewrite it when I get back home, I really appreciate the help!

[dusty geode]

Also if you want to do smoothing in a more correct way look into Mathf.SmoothDamp

[livid grail]

this is where I got my old solution from
https://stackoverflow.com/questions/55963533/unity3d-input-getaxis-for-mouse-not-consistent
with solved my issue with the inconsistency

[queen adder]

        var randTrigger = Random.Range(0, triggersArray.Length);
        animator.SetTrigger(randTrigger.ToString());

So the trigger name is incorrect, its something like "Parameter 0", instead of the actual string of the trigger.
And yes I did put the correct names in the array.

So why doesnt it Trigger with the correct string?

[muted pawn]

try to use

triggersArray[randTrigger]

instead of randTrigger.ToString()

@queen adder

[queen adder]

Yeah I tried it and it works now, thanks

[muted pawn]

youre welcome :)

[dusty geode]

Yeah that is just blatantly incorrect, even the last comment on the answer mentions the incorrectness.

Mouse input is inherently framerate independent. You can easily test this with this script on any object.

public class TestMouseRotation : MonoBehaviour
{
    [Min(10)]
    public int targetFrameRate = 60;
    public float rotationSpeed = 10;
    public float minYRotation = -45.0f;
    public float maxYRotation = 45.0f;
    private float currentYRotation = 0.0f;
    private Quaternion initialRotation;

    void Start()
    {
        QualitySettings.vSyncCount = 0;
        initialRotation = transform.localRotation;
    }

    void Update()
    {
        Application.targetFrameRate = targetFrameRate;

        float rotationIncrement = Input.GetAxisRaw("Mouse Y") * rotationSpeed;

        currentYRotation = Mathf.Clamp(currentYRotation + rotationIncrement, minYRotation, maxYRotation);

        Quaternion localRotation = Quaternion.AngleAxis(currentYRotation, Vector3.up);

        transform.localRotation = initialRotation * localRotation;
    }
}

Is there a 2d equivalent of Gizmos.Draw or is using DrawGizmos fine

[hexed terrace]

a quick google doesn't bring anything up

[west radish]

https://github.com/miguel12345/UnityShapes I've use this, not the best thing but it works

https://openupm.com/packages/com.zchfvy.gizmosplus/ this one also seems interesting, but it's not something ive tried

I find in general that gizmos are perfectly find for 2D use, especially as all I really need them for are circles (ie a sphere), and lines

[hot harbor]

I just want to draw a physics2D.boxcast to help visualize boundaries

what do you think works best?

[slender nymph]

https://github.com/vertxxyz/Vertx.Debugging

[west radish]

just make a cube with the right size to show the rectangle boundary,

[hot harbor]

Thanks!

[west radish]

when viewed side on, a cube is exactly the same as a square

[hot harbor]

Problem was that i'm trying to do this in a statemachine that I wrote for movement, and it is not a monobehaviour so I'm currently scratching my head to figure out what to do; I came across the [DrawGizmo] attribute too

[hot harbor]

This looks really great

[slender nymph]

yeah it's a really useful debugging library and doesn't require changing or adding any logic, just a using alias and the existing physics queries JustWork™️

[west radish]

I forgot about this one!

[hot harbor]

Wow you wrote this!

[slender nymph]

nah, Vertx (one of the mods) did, i just had one PR lol

[hot harbor]

I will check this out!

[frank rivet]

I got like no help at all

[eternal needle]

If your intent is to complain about that, then ok? Not everything gets responded to here. You arent promised help
Otherwise you can actually ask a question for what you need help with.

[teal viper]

It's fine to repost your questions after a while if the original message got buried.

[burnt vapor]

You don't always get a direct answer. Bump your message so people can look at it.

[frank rivet]

ok, sorry that I said that without bumping my message

here

bump

[burnt vapor]

Did you check if Anikki was right with their response?

[frank rivet]

yes but it does not give me any idea on how to make the plane turn to where the free cam is facing

[eternal needle]

use a paste site for the 2nd script, and try to narrow down which part we are supposed to look at. ngl your code is very unreadable because you're combining a lot of logic on one line (like the ternary in the SmoothDamp parameters)
for the problem of turning something to a different rotation you can use built in methods
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Quaternion.RotateTowards.html

[celest shadow]

hey all, I havent worked in unity in a hot minute and I'm picking it back up now. Things feel good but im running into an issue with "completing domain"

if I do literally anything at all, I spend 2 minutes completing domain. remove a comment? complete domain. break point? domain!

is this jsut life in unity now or can I do something?

[naive pawn]

you could turn off automatic recompilation and manually press ctrl+r to recompile/reload assets

[runic lance]

adding a break point should not cause a domain reload though
domain reload is caused either by recompiling the code or entering play mode, the latter can be disabled in the project settings

2 minutes seem an awful lot though, unless your project is huge or your computer very slow

[celest shadow]

I've got a pretty recent cpu and plenty of ram, i dont think its that. Also my project is starting to grow but its no where near what real game devs would consider to be a "big project", like I've got 4 materals, 2 dozen scripts and all my graphics are default cubes and capsules

[runic lance]

it shouldn't take more than a few seconds then

[celest shadow]

is there any feature specifically that takes a lot of work in this process? is it the few shadergraphs I've built?

[shy orbit]

NullReferenceException: Object reference not set to an instance of an object

Why am i getting this when trying to instantiate bullets?

[inland cobalt]

private void Target()
{
    if(Physics.Raycast(_camTransform.position, _camTransform.forward, out RaycastHit hit, _maxDistance))

Hey all, im trying to get my gun model to aim at where my crosshair is pointing, so that it shoots where i expect, in my game my character is able to rotate in the y axis (roll). This code mostly works, however it also rotates the gun in this axis when i dont want it to, how can i cleanly prevent this from happening? Never really sure when dealing with quaternions

[faint osprey]

how do i reference the right value

    {
        while(progressBar.rect.xMax < 200)
        {
            progressBar.rect.x += 1;
            yield return null;
        }
    }```
i tried this but it says it cant be modified cause its not a variable

[celest shadow]

you probably havent set a bullet prefab object in the script

check the component on its game object and see if theres a blank space there for your prefab

[shy orbit]

no i have, its there

[celest shadow]

then you need to check the stack trace because something deeper down is null. your error doesnt tell much

[runic lance]

it's mostly related to scripts and serialization/deserialization
if you're on Windows, maybe your project is being synced with OneDrive constantly? or maybe Windows Defender is doing something weird with it?
I think you're able to open the profiler and inspect what's causing the long loading times, but looks like it's something external

[naive pawn]

you can't modify that rect, you have to replace it

[shy orbit]

well this is the code i have for it

using UnityEngine;

public class Weapon : MonoBehaviour
{
    public GameObject Bullet;
    public Transform firePoint;

    public void Fire()
    {
        Instantiate (Bullet, firePoint.position, firePoint.rotation);
    }
}

and

public Weapon Weapon;
if (Input.GetMouseButtonDown(0))
        {
            Weapon.Fire();
        }

[naive pawn]

    private IEnumerator DecreaseOxygen()
    {
        while(progressBar.rect.xMax < 200)
        {
+           Rect rect = progressBar.rect;
+           rect.x += 1;
+           progressBar.rect = rect;
-           progressBar.rect.x += 1;
            yield return null;
        }
    }
```something like this @faint osprey

[celest shadow]

id recommend a breakpoint and inspecting the values of these at runtime. if everything is set correctly at runtime then you shouldnt get a null ref

[shy orbit]

how do i do that?

[naive pawn]

where's ProcessInput?

[shy orbit]

the if statement is inside ProcessInput

[naive pawn]

is it that second codeblock?

ok

[celest shadow]

uhhh are you using visual studio?

[shy orbit]

yeah vsc

[faint osprey]

that still gives me an error on progressBar.rect = rect cause it says its read only

[naive pawn]

and line 37 is pointing to Weapon.Fire, right?

[shy orbit]

yeah

[naive pawn]

vsc is not visual studio, which one are you using

[naive pawn]

ok, so it's Weapon that's null

[shy orbit]

im using vsc

[naive pawn]

check your PlayerController, have you assigned Weapon correctly?

[celest shadow]

you can put a breakpoint on any line if you click the gray bar on the left side. using the green "play button" near the top will attach your visual studio to the unity process. When you call that method, you will hit the breakpoint. The editor will freeze and you can then go to vsc and inspect local values

[shy orbit]

its assigned as public Weapon Weapon;

[naive pawn]

(also btw, the variable should probably be weapon instead, so you can differentiate between the class and the variable

[naive pawn]

that's a declaration; you'll have to assign it somewhere in your script or within the editor

[celest shadow]

it will look like this

[naive pawn]

do you have any Weapon = ... in your script?

[shy orbit]

i dont no

[naive pawn]

shit, mb, nvm

im now noticing that you're calling this a progressBar, why not use a slider for that?

[inland cobalt]

anyone

[naive pawn]

read your script. do you have any Weapon = ... in PlayerController

[shy orbit]

no i dont, what would i put after the = tho?

just weapon = weapon?

[naive pawn]

in my game my character is able to rotate in the y axis (roll)
the y axis isn't roll

[naive pawn]

you don't need it

im just asking if you have it

[shy orbit]

oh nah i dont

[naive pawn]

have you set Weapon in the inspector, then?

[inland cobalt]

sorry i forget its the other way around in unity, regardless, i meant roll

[wintry quarry]

you sure you don't have it in Awake or Start or something?
like weapon = GetComponent<Weapon>() for example

[naive pawn]

wait this is meant to be "i don't, no" right? i misread it as "i don't know" lmao, sorry

[shy orbit]

here ill send my entire code one sec

    [SerializeField] private float playerSpeed;
    public Rigidbody2D rb;
    public Weapon weapon;

    private Vector2 moveDirection;
    private Vector2 mousePosition;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    

    // Update is called once per frame
    void Update()

       ProcessInput(); 
    }

    void FixedUpdate()

    {
        //Moving
        float moveX = Input.GetAxisRaw("Horizontal");
        float moveY = Input.GetAxisRaw("Vertical");
        moveDirection = new Vector2(moveX, moveY).normalized;
        //Aiming

@shy orbit

[shy orbit]

AH

found it

thank you

[wintry quarry]

No that's not it, unless you found something else

[shy orbit]

weapon wasnt set in the Player inspector

[wintry quarry]

Exactly

[shy orbit]

thank you guys

works now 🙂

[naive pawn]

@inland cobalt so your character is rolling in first person, the camera is also rolling, the gun is also rolling, but you want the gun to not roll?

[inland cobalt]

i want the gun to roll with my camera, but the issue is the script above that attempts to make the gun aim at the crosshair, which counteracts that rotation when looking at the raycast hit point, the weapon is a child of my camera offset

[naive pawn]

would rolling the gun along the axis it's pointing be viable? (as opposed to rolling the gun along the player forward axis)

i think that would be (more easily) achievable

[celest shadow]

hey, I've made a bunch of game objects, is there a way in the inspector to count how many of these have spawned?

[naive pawn]

select them all the hierarchy and see how many you've selected?

[celest shadow]

is there a number for that anywhere? I dont see it

[naive pawn]

it might show a number if you try to drag them?

im not sure unity has that

[celest shadow]

there is!

[naive pawn]

ah, nice

[celest shadow]

almost 900 and I'm starting to lag

[inland cobalt]

sorry mind clarifying what you mean? Im not sure i follow

[naive pawn]

your current player/camera rolling is around the player's forward axis, right?

[inland cobalt]

yes

its the player rolling, with the camera attached to them

[naive pawn]

but the gun is misaligned from that axis, right, since it's not pointing straight ahead, but towards the center of the screen

[inland cobalt]

yes

[naive pawn]

so would the rolling be done around the gun axis or the player axis? i think the former would be easier

[fleet venture]

Can i have like a global gameobject but still have public fields that have some references to a few different scenes?

it can just keep them like null when the object dont exist if the scene isnt loaded?

[inland cobalt]

But im rotating the gun with LookAt(), im not rolling relative to anythings axis surely, just pointing at a position in space

[wintry quarry]

you cannot reference objects in other scenes except at runtime when both scenes are loaded.
You cannot reference scenes themselves.

[polar acorn]

A singleton, but when you're writing the code for the instance to self-terminate, first have it beam its references to the existent singleton

[naive pawn]

right now you have that, i mean what do you want

[fleet venture]

oh

how do i work around it

ill give a bit more context

[inland cobalt]

i want it to do what its already doing, without affecting the roll axis at all

so that it remains rolling with the player

[fleet venture]

i have an ApiManager script/class that talks to my backend.
this will have methods like login and register which happen in the login scene.
i have that working.
This generates a token that i want to share between all scenes but it can remain privately inside the ApiManager (like i want it to be private in there preferably).

Then when you have logged in the scene should switch and you will be able to call some other Api methods, which take different input fields in the second scene. but the token of the first will be needed there

i hope thats a sort of good explanation of the issue

rn i just have it working in a single scene

[celest shadow]

why is the editor killing me?

[celest shadow]

you could mark the object as DontDestroyOnLoad and it will hang around between scenes. Just be careful if you load a scene that has the object in it, you could hit some conflicts. Best to instantiate it programmatically and use a singleton pattern to make sure it only happens once

[fleet venture]

what about ScriptableObject

i also found stuff on that

[crystal bridge]

Hello, very new to coding and here. I have an object that I want to increase in size to be view by the player (common troupe down by simply clicking on the object with mouse button). The code I have here accomplishes that.

My problem is that the image is rotated when small (deliberate). I want the mouse click to simultaneously rotate the image to a normal view and center the image on screen when it expands.

[celest shadow]

I dont know much about scriptable objects sorry

[fleet venture]

ok ill try to figure that out ig

[wintry quarry]

You can't have two methods with the same signature like that

If you want to do both things when clicking it, jsut put all of that code inside the one method

[crystal bridge]

Originally I did that, but while it doesn't give errors, it doesn't rotate.

[wintry quarry]

it rotates

just by a very small amount

OnMouseDown only runs exactly at the moment you click the mouse

you're doing ONE FRAME worth of rotation

if you want to do something over the course of many frames, you'll need to do it bit by bit in Update

or use a coroutine

[eternal needle]

you wouldnt really be using the SO for its purpose here. its more of a immutable data container for you to populate. it doesnt actually save the data if you're changing it in a build
An object in DDOL could be fine, but do you need this to be a unity object? You could just go ahead with the singleton and use a plain c# class

[crystal bridge]

Yeah, I want only one frame (no animation). I increases the rotation speed to higher values (50f) to see if there was a noticeable increase, but no change.

[wintry quarry]

just set the rotation to the desired rotation then

why are you using transform.Rotate and multiplying by deltaTime?

That would be something you do each frame to get a constatnt rotation over time

transform.rotation = whateverNewRotationYouWant;

[crystal bridge]

Tutorial that I tried to adjust 😶

[red igloo]

Im making a 3D platform game, this is my script how can I make it so when you press D the player will move forward A move backward W move away from the camera and S move close to the camera.

https://paste.ofcode.org/uRPTRiMeFkbMAQZ9AAqQ9D

[fleet venture]

Uh ye maybe idk

[wintry quarry]

Looks like you're currently trying to transform the input based on the direction the object the script is attached to (the player?) is facing:

Vector3 MoveVector = transform.TransformDirection(PlayerMovementInput) * speed;```

if you want to do it based on the camera, you would do something similar, but with the Camera's Transform

but you might also want to project those directions on the x/z plane to make it "flat" if the camera is tilted down

[fleet venture]

Im back in a bit

[eternal needle]

the only difference if its a monobehaviour is you'll need to use DDOL for your singleton too

well theres more differences ofc but you can still use it the same as a plain c# class

[fleet venture]

But ideally I would have a diff api script so it can have diff input fields in each scene so then I only need to share some variables and not keep the entire object

Otherwise I can’t have multiple input fields from diff scenes

[eternal needle]

this is really vague and honestly got no clue what this has to do in relation to your initial problem of a token that you can share between scenes

[fleet venture]

Like I login on scene one and I get a token that I need to pass to scene two to do more api stuff with

[crystal bridge]

Like this?

[wintry quarry]

no...?

Clearly that's not right, given the errors you're getting

can you explain what you want to do exactly?

[eternal needle]

yes that is the initial problem of "a token that you can share between scenes". The whole rest of the message was vague. It'd be a lot easier to understand if you could share the code that you're struggling with

[wintry quarry]

What's the new rotation you want to achieve here?

[crystal bridge]

While object is small, it is also crooked and a mouse click expands it for the player to view. This also means that it remains crooked, but I want the crooked object to become corrected while it is big. When player clicks on the object while big, it should return to being small and crooked.

[red igloo]

Like this?

Vector3 right = cameraTransform.right;
Vector3 forward = Vector3.Cross(right, Vector3.up).normalized;

[wintry quarry]

that's really vague

[fleet venture]

i dont have a github repo cuz i didnt know how to do that with unity

[crystal bridge]

I'd also like the object to be centered on screen while big, but return to origin when small

[polar acorn]

What value do you want to set the rotation to

[fleet venture]

i am first going to eat tho

ill be back in a bit

[wintry quarry]

so what rotation do you want

[wintry quarry]

Vector3.ProjectOnPlane

[crystal bridge]

I was planning on adjusting the value after coding was set correctly, but the object is a square shape that should be 90 degrees.

Well, turning counterclockwise

[wintry quarry]

counterclockwise around what axis

[crystal bridge]

Side Note, this is all 2D is that wasn't mentioned

[wintry quarry]

so you just want to rotate 90 degrees CCW from the curent rotation

[crystal bridge]

Probably less, but essentially yes

[wintry quarry]

transform.Rotate(0, 0, -90);

or transform.rotation *= Quaternion.Euler(0, 0, -90);

[crystal bridge]

Cool, these both worked in rotating. Can you explain the difference?

[wintry quarry]

there is no difference. They do the same thing

although Rotate rotates around its local axes, which are the same in this context

[crystal bridge]

So now each click rotates it by the specified amount which makes sense, but I want it to be locked after the first click while big and vice versa while small.

So end results would be while small, it is crooked in starting position.
While big, it is fixed upright (rotated as we just did).
No other positions/states would be allowed.

[wintry quarry]

You shouldn't be using Rotate really then

or additive rotation then

you shoiuld have two set rotations

and switch between them

[fleet venture]

ok im back what code do you need

public class ApiClient : MonoBehaviour
{
    private PostLoginResponseDto _postLoginResponseDto;
    
    public TMP_InputField email;
    public TMP_InputField password;
    
    
    
    public async void Register()
    {
        var dto = new PostRegisterRequestDto { email = email.text, password = password.text };
        await PerformApiCall("[redacted]", "Post", JsonUtility.ToJson(dto));
    }
    
    public async void Login()
    {
        var dto = new PostLoginRequestDto { email = email.text, password = password.text};
        var response = await PerformApiCall("[redacted]", "Post", JsonUtility.ToJson(dto));
        _postLoginResponseDto = JsonUtility.FromJson<PostLoginResponseDto>(response);
    }
}``` this is pretty much all that i have rn

and the postloginresponsedto contains the token

that i want to share between scenese

with other api clients

[crystal bridge]

As for a sorta 'glitch' (but not really), I notice that clicking once on object rotates it while small, click again makes it bigger. I'm trying to have both happen in one click.

I think I get what you're syaing. Like making a default position for the small size -> mouse click -> object changes to big and in different position.

[crystal bridge]

Not sure how I'd set that up while retaining size changes. Should the positions be a separate script?

[eternal needle]

🤷‍♂️ you said here something about a problem #💻┃code-beginner message
im not sure what code you have or still what the problem even meant.
as for the token, still just a singleton should be fine

[wintry quarry]

empty GameObjets would be easiest

[fleet venture]

i jsut dont rly know how to do the singleton thing

[fleet venture]

should i not put it on this class then?

[wintry quarry]

learn!

[fleet venture]

why would i even need a singleton at that point cant ijust make it static?

[eternal needle]

thats up to you, im not sure what the lifetime of that object is intended to be. from your initial messages it sounded like you had some ApiManager class which i assumed you would make a singleton and put the token on

[fleet venture]

wellit was but i need references to scene objects from multiple scenes

[wintry quarry]

make what static

[polar acorn]

https://gamedevbeginner.com/singletons-in-unity-the-right-way/

[fleet venture]

so that means i need multiple ApiManagers

like one for each scene

[eternal needle]

as it was written before, use DDOL (DontDestroyOnLoad) 🪄

you should really just look at what a singleton is before making these assumptions

[fleet venture]

i thought that did not work with object references accros multiple scenes

[fleet venture]

i know what the concept of a singleton is

so if i do use a singleton can i put referenes to objects on scene 1 AND scene 2 in it?

[eager elm]

You should never put scene references in a singleton since they won't exist / will be destroyed.

[fleet venture]

public class ApiTransferData : MonoBehaviour
{
    public static readonly ApiTransferData Instance = new();

    public string Token { get; set; }
        
    private ApiTransferData() { }

    private void Awake()
    {
        DontDestroyOnLoad(this);
    }
}``` so is this just what you mean?

like i put only the data in it?

[wintry quarry]

what exactly are these things you're referencing?
I think you kinda have it backwards. YOu don't need a singleton to hold references to stuff.

THe things you want to hold references to should just be singletons themselves

The point is you can access a singleton very easily from anywhere.

[fleet venture]

they are input fields in the scene

like you can type stuff in it

[wintry quarry]

that's very vague

[fleet venture]

how is that vague

[wintry quarry]

are these part of a menu

[fleet venture]

this

[wintry quarry]

because i don't know if it's like a thing there's 500 of or an entry form

[fleet venture]

text mesh pro input fields

[eager elm]

have a second class that handles the input fields and then writes to the singleton

[wintry quarry]

Ok cool - wrap this up in a script and make that script a singleton

then you can access it anywhere

[fleet venture]

ye okay

[wintry quarry]

like EntryForm.Instance.DoWhatever();

[fleet venture]

oh well i dont rly need that i only need the result of the operation to be a singleton

but i think i got it

[fleet venture]

this solves it i think

[eternal needle]

you cant new a MonoBehaviour and no this isnt a singleton pattern that'd work in unity. One was linked to you above

[fleet venture]

i copied it from the website

[naive pawn]

what website

[fleet venture]

i guess i mixed a few things

[naive pawn]

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

singletons have the same concept in unity as in normal OOP, but a different implementation

[fleet venture]

so this then

public class ApiTransferData : MonoBehaviour
{
    public static ApiTransferData Instance { get; private set; }
    
    public string Token { get; set; }

    private void Awake() 
    { 
        if (Instance != null && Instance != this) 
        { 
            Destroy(this); 
        } 
        else 
        { 
            Instance = this; 
        } 
    }
}```

[wintry quarry]

not quire

[fleet venture]

thats literally copied form that link

[wintry quarry]

close

no it isn't

[wintry quarry]

ah that link

that link is doing it wrong apaprently lol

[fleet venture]

oh

💀

[wintry quarry]

it should be Destroy(this.gameObject);

[fleet venture]

whatabout this

[naive pawn]

what website is this

[fleet venture]

public class ApiTransferData : MonoBehaviour
{
    public static ApiTransferData Instance { get; private set; }
    
    public string Token { get; set; }

    private void Awake()
    {
        // Destroy this object if we already have a singleton configured
        if (Instance != null)
        {
            Destroy(gameObject);
            return;
        }

        Instance = this;
    }
}```

[fleet venture]

its this one

[naive pawn]

use this @fleet venture

[fleet venture]

ye i did that now

[queen adder]

Just make a generic base class for singletons

Inherit from it when you want to expose a singleton instance for the class

[wintry quarry]

how about we crawl before we run

[fleet venture]

i only need one though

[queen adder]

Good point I'll just let you guys chill

[fleet venture]

do i just append DontDestroyOnLoad(this); in the Awake?

so how do i reference the singleton?

[polar acorn]

The static variable

[fleet venture]

oh

ye ofc

i thought cuz it was Monobehaviour that wouldnt work

so i do need to put this on a gameobjectright?

what happens if i load the scene for a second time with that object

[polar acorn]

What does your code say it does when there's already an instance

[fleet venture]

oh it destroys

okay

[eternal needle]

maybe it assumes the object could have other components on it

[wintry quarry]

Indeed but that's an unusual approach and you would also need some kind of manager keeping track of all the GameObjects then as well

Otherwise you'll end up piling up empties

[eternal needle]

Yea no doubt its better to destroy the GO. they probably just wrote it as a safety, or maybe im looking too deep and its just a mistake

[faint osprey]

tetherJoint.connectedAnchor = tetherAnchor.position;

im trying to assign the correct anchor position but because its a child of something its putting its local position in as the value how do i do it so its the world position instead

[wintry quarry]

the connected anchor position will be in the local space of the connected Rigidbody

so the proper answer to this would be:

Vector3 worldPosition = tetherAnchor.position;
Vector3 positionInLocalSpaceOfConnectedBody = myConnectedRigidbody.transform.InverseTransformPoint(worldPosition);
tetherJoint.connectedAnchor = positionInLocalSpaceOfConnectedBody;```

(this is a little verbose but I did that on purpose to explain each step thoroughly)

[faint osprey]

oh so because it is connected to the player that means its position is local to the players world pos

[wintry quarry]

if you have already assigned the connected body to the joint you can replace myConnectedRigidbody with tetherJoint.connectedBody

[wintry quarry]

The connected anchor position is relative to the player's local coordinate system

not just their position

[red igloo]

also how do I stop the player from climbing the box like that very annoying.

https://paste.ofcode.org/M9ULxsCVdaffePNYyuePmj

https://streamable.com/3tg9bb

[eternal needle]

which part of it are you trying to solve, that its pushing a box or that it's moving on such a steep angle? for the angle you'll have to cast down, likely using a capsule cast, and then check the normal of what you're standing on to see if you should be able to move or not

[crystal bridge]

Earlier issue resolved, thanks Community Members!

My next thing is I have a DragDrop function that is working. Objects grabbed by the cursor can be moved around the screen and 1 specific object (TrashSlot) cannot be dragged, but instead allows draggable objects to lock into it (typical inventory slot mechanic).

What I want to happen is as soon as object locks into the slow, it gets destroyed. The following code is accepted, but the objects are not disappearing.

I have tagged the objects and the slot with "TrashSlot"

[strange gate]

public void OnDamage(float dmg){
        if(invulnerable) return;
        invulnerable = true;
        TakeDamage(dmg);
        StartCoroutine(DamageDelay());
    }
    private IEnumerator DamageDelay(){
        Debug.Log("Entering DamageDelay coroutine.");
        yield return new WaitForSeconds(1.0f);
        invulnerable = false;
        Debug.Log("Vulnerable!");
    }

It never runs the DamageDelay() for some reason, how can I fix this?

[rich adder]

do you want the box to rotate like that at all ? You could also just lock box rb X/Z rotation ?

[vital nexus]

was wondering if anyone could share there thoughts on why the item doesnt respawn

[eternal needle]

have you debugged if the OnTriggerEnter2D function is being called? you have debugs in the other methods

Hi, I am making a music visualizer app in Unity and I'd like to launch it on startup.
I can't figure out how to access the windows registry because including Win32 is apparently not enough in unity.
What am I supposed to do?

[rich ice]

seems like you never call "DestroyItemAndRespawn"

[umbral bough]

Googling was useless btw because p much all the forums just tell you to use player prefs because nobody wants to answer the question but they do wanna play smart.

Sorry, what do you mean by that? Im pretty new to Unity so I dont understand these terms so much yet

😅

[rich adder]

hmm..first did you verify that OnDamage gets to start coroutine line at all? I don't see a log in that method

[red igloo]

if you watch the video when I am pushing the object the player climbs up which I dont want

[vital nexus]

this is within my player script, that destroys it

[umbral bough]

as I said, I don't have access to RegistryKey

[red igloo]

I need it to still rotate

[eternal needle]

yes i saw, the rest of my answer above addresses that

[rich adder]

it will still rotate just not angled

[strange gate]

I had a few extra logs before this, the OnDamage() gets executed, but it doesnt execute coroutine

[rich adder]

did you add the dll properly?

doesn't seem so

[umbral bough]

wym add the dll?

[rich adder]

unity doesn't include those assemblies because they are not crossplatform

you have to add any DLLs you want to get access to

[umbral bough]

ah, is there a way to include it only if it's a windows build?

I am building for both linux and windows so idk what to do tbh

[rich adder]

sure

in the plugin there is a platform tickbox

[umbral bough]

so do I just get the dll online or unity pm or what?
never added dlls before

[rich adder]

gotta find the path for linux. Thats tricky I suppose because so many different distros

[rich adder]

You just put it inside your Assets/Plugins

[umbral bough]

it's fine, linux users are usually capable of handling the startup themselves, making it launch on startup on windows is the priority, will take care of linux afterwards

[strange gate]

Just fixed the problem, i started to test each line and turns out it was TakeDamage that was the problem

Thank you for the help!

normally its already there in the .net framework folders unity downloaded, its jutst omitted or you can download nuget packages and extract them like a zip to take the DLL from lib folder with correct .net version.

i found this though . Doesn't use win32

string startupFolder = Environment.GetFolderPath(Environment.SpecialFolder.Startup);
        if (Directory.GetCurrentDirectory() != startupFolder)
        {
            string path = Path.Combine(startupFolder, "MyFile.exe");

will give it a try, thanks for doing the digging for me

[loud vault]

Something about my game's resolution is off. In windowed mode the game looks good, but in full screen the edges are jagged
Another thing is that to take a pic of the jagged graphics I had to take a pic with my phone, because if I take a screenshot it looks like in the windowed version
Maybe it has something to do with the monitor resolution settings?

[rose canopy]

i think my unity might be bugged?
On one project im able to multiply float by Vector3
float deez = deez * transform.right;

But on another project this gives me an error saying that you cannot convert vector3 to float. Am i missing something????

[rich adder]

this is a code channel

[rich adder]

deez * transform.right returns a vector3 not float

imagine Vector(1,1,1)
and float is 3

3 x 1 , 3 x 1 , 3 x 1
= Vector3(3,3,3)

[naive pawn]

On one project im able to multiply float by Vector3
But on another project this gives me an error saying that you cannot convert vector3 to float
these are not contradictory, these are simply different things (that are both true)

[rose canopy]

this same line of code in 2 different projects one returns an error

[loud vault]

Where am I supposed to ask? Under the art channels?

[rich adder]

what?

this is literally not a float

[naive pawn]

perhaps #🖼️┃2d-tools or just #💻┃unity-talk, but i think that's just a moire effect?

[crystal bridge]

Sorry, I had missed this, but upon reevalutaing I shortened the code and more importantly forgot to add rigidbody to one of the objects (I had thought I did this).

[loud vault]

The moire effect is because I can't show the low resolution without taking a picture with the phone, because any screen capture shows the correct resolution, but not the gameplay

I'll try in unity talk

[west radish]

there is no way that you could have written float deez = deez * transform.right; that line in itself it not valid C#

[eternal needle]

i dont think you need a rigidbody, id possibly not even use OnTriggerEnter2D here actually. If you drag it over the trash without letting go, wouldnt it delete the object in that case?
Maybe when the drag is finished, do like an overlap circle to get all the colliders around the area

[west radish]

even this shouldn't work float deez = 1f * transform.right

[rose canopy]

i figured out why i didnt get an error when i wrote that maybe? i didnt have the actual unity project open i just had the script cause i wanted to test if i would get an error writing it in a different project?

[grim eagle]

why is "playerscore + 1" red? (this is VERY basic mb 😭) (i'm following a pre unity 6.0 tutorial)

[polar acorn]

Because you have to put the result somewhere

You're just adding one and doing nothing with it

[polar acorn]

At no point in Unity history would this have worked. You cannot store a Vector3 in a float

[grim eagle]

this?

[polar acorn]

Yes, that would store the result in the playerScore variable

[umbral bough]

hmm, from what I can tell, this will just copy the exe to the startup dir on windows, no?

[grim eagle]

thanks!

do i need to add "class"?

[wintry quarry]

Looks like you're trying to use a script called "LogicScript" which you didn't create

Are you trying to follow a tutorial or something

[grim eagle]

ooh, could be

[grim eagle]

yes but my dumbass keeps renaming stuff 😭

[wintry quarry]

If you're following a tutorial, you missed a step

or

yes

you named it something else

I recommend if you're following a tutorial to do it verbatim

Tutorials are for learning

they're not for creating an end product. You watch the tutorial to learn how it works, then apply those learnings to create your own thing.

it doesn't work

[humble marsh]

Hello! how do you get a rotated transform localpoint to world position? transform.transformPoint() doesnt seem to work, as the selected cube is where it is in local spaces, but where the wood is, is where it goes to when made into world space.

[swift crag]

Perhaps you meant to use its parent transform

TransformPoint takes you from the local space of a Transform to world space

The position you see in the inspector is your local position, whose world-space meaning depends on the parent transform

[humble marsh]

yes, i want to make it into COMPLETELY world space. ie no parent

but when i use the function to transform it into world space it teleports the point to another location

[swift crag]

where is this local position coming from?

[humble marsh]

logcutting1 has a attached collider, the collider min and max is in local space compared to the logcutter

i use logcuttor to transform it into world space

[swift crag]

there is no "logcutting1" or "logcuttor" object in this screenshot

[humble marsh]

I mean to say Logcutting(Clone) mb

[swift crag]

okay, so you have a box collider attached to "Logcutting(Clone)"

show your code

[humble marsh]

yes, i have it attached, and i get the min / max by using center +- size/2

https://paste.ofcode.org/WeDDttsN9iie9ZkrHKfCuM

im trying to transform all points into world space, to use for calculations.

[rose canopy]

I have a top down game, im procedurally tilting the character model based on input. but when i rotate the character model to say look left, and then i start moving, it tilts based on its rotation so clicking W which moves you up it would Yaw left instead of pitching down, how do i make it tilt based on world XYZ or even based on the Character Controller rotation which doesnt rotate?

[swift crag]

what object is this component attached to?

you're using transform, so you're getting the Transform of that object

perhaps you meant to use collider.transform

[humble marsh]

the Birch_1 object, and yes i know, i tried that when collider.transform.transformpoint didnt work. as you can see in the comment

[swift crag]

well, collider.transform.TransformPoint is the correct thing to do

it will transform a point from the local space of the collider's Transform to world space

and you've calculated a point in the local space of the collider's Transform

[humble marsh]

yeah, which is pretty wierd, since in local space, the collider min/max are on the collider, but when transformed into world space they just, arent

[swift crag]

use Debug.DrawLine to draw a line from the origin to the calculated world positions

give it a long lifetime so it doesn't instantly vanish

[wintry quarry]

Hey are you sure your tool handle position in the scene view is set to Pivot and not Center?

[swift crag]

that would make things more confusing, yes

[humble marsh]

so, wierd problem. uh, drawline fixes the position.

but yes, the handle is pivot

[wintry quarry]

Did you check this @humble marsh

ok

[humble marsh]

I'm going to have to debug more, the issue is sometimes fixed. sorry to waste your guys time, and thank you.

https://docs.unity3d.com/6000.0/Documentation/Manual/ios-detect-game-controllers.html Hi im using this to detect if a controller is connected - if i disconnect my controller its still true

[rocky canyon]

it doesn't immediately update when the controller is disconnected

it can take some time b4 unity registers the disconnection

the new input system wil update instantly i think..

you could poll Input.GetJoystickNames(); every second or so..

[sour fulcrum]

All definitions of ScriptableObject and MonoBehaviour classes have to be in their own .cs file with 1:1 matching names for serialization purposes right?

[swift crag]

Names don't have to match in newer versions of Unity

but yes, you may only declare one such class per file

Unity only cares about the GUID of the ScriptAsset.

[sour fulcrum]

ah pain, ty

have a handful of classes i gotta define explicit generics for and it would be a lot cleaner to just knock them all out in 1 file aha

eg.

[CreateAssetMenu(fileName = "EnemyManifest", menuName = "GAME/ScriptableManifests/EnemyManifest", order = 1)]
public class EnemyManifest : ContentManifest<ScriptableEnemy> { }

[CreateAssetMenu(fileName = "ItemManifest", menuName = "GAME/ScriptableManifests/ItemManifest", order = 1)]
public class ItemManifest : ContentManifest<ScriptableItem> { }

[CreateAssetMenu(fileName = "InteriorManifest", menuName = "GAME/ScriptableManifests/InteriorManifest", order = 1)]
public class InteriorManifest : ContentManifest<ScriptableInterior> { }

oh well

[swift crag]

cool trick: you can use consts in attribute parameters

so you could write Menus.ManifestPrefix + "EnemyManifest"

as long as ManifestPrefix is a const string

[sour fulcrum]

oh fair, i could probably through in a nameof there too right

[swift crag]

that too

[sour fulcrum]

The documentation is also worth reading.

https://docs.unity3d.com/6000.0/Documentation/Manual/working-in-unity.html

I wouldn't just read the scripting documentation from start to end -- you want to look in the manual

It covers higher-level ideas, like game objects and components

How do I get the vectors perpendicular to the transforma.forward vector?

[polar acorn]

Cross Product gets a vector perpendicular to the two input vectors

[swift crag]

This is a bit tricky in general!

I mean, in this case, you can just use transform.up and transform.right

[scenic saffron]

Thx

[polar acorn]

There are an infinite number of perpendicular vectors for a given vector in 3D space

So you need another one to choose which of those you want

[swift crag]

But generally: consistently finding two tangent vectors is hard. There's no general way to pick them with no context.

You can start with world-up and then orthonormalize (make the two tangent vectors perpendicular to both each other and the original vector) -- but then it freaks out if the vector points straight up

It's an interesting problem. It comes up quite a bit in shaders..

this is the same problem that comes up for Quaternion.LookRotation

if you ask for a look rotation that's straight up, you'll get weird results, because LookRotation defaults to using Vector3.up for the "up" direction

ive recently been getting a lot of errors about "ambiguous references" that i never got before on my project, why is this happening cause everything seemed fine until this popped up, and i didnt even change anything

Is there a simple way to visualize a RaycastHit2D array?

[verbal dome]

Loop + Debug.DrawLine

[vagrant mist]

So inside of an update method or make a loop?

[frosty hound]

Wherever you made the raycast, just add the Debug draw after it.

[vagrant mist]

where I made it or where I'm casting it?

[frosty hound]

Casting

[vagrant mist]

Debug.DrawRay or DrawLine?

[frosty hound]

Either will work

Ray will take a point and direction, and line will take a point and destination.

[vagrant mist]

so I think I want to do Ray, now the arguments themselves confuse me a bit
I'm thinking Debug.DrawRay(Vector2.zero, Vector2.down, ---);
not sure about what to do where I put the dashes

hol up, intellisense mightve saved me

[frosty hound]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Debug.DrawRay.html

[vagrant mist]

I dont think either of those helped

so I recompiled it and everything runs fine, but there are no lines being drawn

  public ContactFilter2D castFilter;
  public float groundDistance = 0.05f;
  CapsuleCollider2D touchingCol;
  RaycastHit2D[] groundHits = new RaycastHit2D[5];

 public bool IsGrounded { get
     {
         return _isGrounded;
     }
     private set {
         _isGrounded=value;
         }
 }

  private void Awake()
{
   
    touchingCol = GetComponent<CapsuleCollider2D>();

}
  void FixedUpdate()
{
  IsGrounded = touchingCol.Cast(Vector2.down, castFilter, groundHits, groundDistance ) > 0;

   Debug.DrawRay(Vector2.zero, Vector2.down, Color.yellow, 10);
}

this is roughly what it looks like

[frosty hound]

Do you have gizmos turned off?

You're also using the world origin, so are you looking in the wrong place?

[vagrant mist]

i could be, gizmos all look good

how would I change it to target the player?

[frosty hound]

Give it the position of the player for the first argument.

This script is on your player, no? Use transform.position, then.

[vagrant mist]

yeah its on there, this is actually a separate script for this specifically

I'm trying to see why my isOnWall and isOnCeiling bools keep going on each time my player lands on the ground because I think its the reason my player stops for a split moment and loses all speed

[drifting cosmos]

is there a default scene that loads when you launch the game like how does it know which scene to load

[teal viper]

Depends on the scene ordering in the build settings

[sour fulcrum]

In THEORY setting RenderSettings.skybox to a instanced version of itself made at runtime should make it safe to mess with without messing up the editor one, right? Assuming the active scene has not changed between me applying my new material and me messing with it

I was under the impression RenderSettings.skybox directs to the active scene's skybox, no?

why are my logs saying otherwise 😭

can you really not access the rendersettings of additive scenes even if they are actively being used?

oh you can use resources.findobjectsoftypeall but that seems disgusting

[frigid sequoia]

If a script has Coroutine running, what would happen first, the Update method of that script or the Coroutine?

It's random by default?

[sour fulcrum]

https://docs.unity3d.com/6000.0/Documentation/Manual/execution-order.html

[frigid sequoia]

Mmmm, makes sense I guess

[sour fulcrum]

can i just not fuck with the skybox when using additive scenes without some hdrp nonsense?

the answers im finding online are insane

[chilly magnet]

Any beginners, DM me, I am working on a cool hobby project and I am looking for people to help me.

[teal viper]

If you mean the lighting settings, I think the lighting settings of the active scene are used normally. So you can manually set the scene as active to use it's lighting settings.

[sour fulcrum]

this is true

but you cannot modify them

from what i am reading and trying

[teal viper]

Not sure about that.

[chilly magnet]

thx man

[sour fulcrum]

as in your not sure about that or that doesn't sound right?

[teal viper]

Both

What setting exactly are you trying to change?

[sour fulcrum]

I've got a lobby scene and a level scene, the latter additively loads and unloads on request

I have a time of day system and wanted to manipulate the level skybox to reflect the time of day

I agree in that it doesn't sound right but honestly seems cooked

RenderSettings is exclusively static calls to c++

I was hoping they existed per scene and they do but there's nothing actually in each of them i can touch

[frigid sequoia]

Ok, this is kinda more of an organization thing, but I may ask anyways. When you have like something that can be either one thing or the other, do you guys use a bool or create an enumerator for it?

Like let's say u have physical damage and magic damage. Do you call it by bool isMagicDamage or do u specifcy it?

[eternal needle]

for damage types, id just make an enum incase i ever add more later. it also just makes more sense logically like it can be physical or magic. its not really a case of "is it magic or not"

[sour fulcrum]

Not to overengineer but scriptableobject might also be nice for damage type for other related data, even just visual stuff like icons

[frigid sequoia]

It does make more sense, but it's kinda inconvenient to set up when I know for sure there is only going to be 2 types

Also, probably slightly worse on performance??? Not sure

[eternal needle]

the inconvenience lasts 5 seconds and just makes more logical sense. logical code is good

and please dont bring up the performance of an enum with 2 values compared to a bool. we're talking nanoseconds differences here

[frigid sequoia]

Most things on your code amount to nanoseconds tbh, but on each script on each frame, it does add up

[wary sable]

Hello,

I am making a basic movement controller for a cube, and want to give it a jump function that allows it to keep its horizontal momentum after jumping. I have tried a few ways like directly changing the velocity but that doesn't seem to do it. My next assumption would be to somehow create a vector based off of the x and z velocities and multiply that with vector3.up in an Add force, but I'm a little lost. A hard shove in the right direction would be apprecitated!

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

[frigid sequoia]

Not much, but not sure if I would go through the slight hassle of making it an enum for readability when I am the only one that is gonna read it anyways if it's also gonna be worse in the end

[eternal needle]

i feel like you dont know the scale of a nano second if this is what you really believe. ive seen this repeated by others and really, just no.
stuff like this will NEVER add up to become a performance issue. performance issues in most cases will happen from simply doing too much logic (trying to update 5000 objects per frame)

[frigid sequoia]

I do know, but stuff like this are gonna happen like constantly on the game, so why make it more complex for no reason, even if only slightly?

[eternal needle]

you're combining transform and rigidbody movement, you should just choose one. i dont see anywhere here where you actually assign a horizontal velocity so the x and z value of your velocity are likely always 0

[frigid sequoia]

I don't think it's really that much easier to read, or is it?

[sour fulcrum]

not to nitpick but incoming with 1 m and not 2

[wary sable]

oh yeah that would do it lol

thanks

[eternal needle]

you wouldnt be making these claims if you knew more about performance and truthfully i dont think i can convince you otherwise. i do suggest though actually looking into this yourself with benchmarks instead of just repeating the silly statements others say of "it adds up"

[sour fulcrum]

Unity probably does one thing stupidly somewhere that costs more than hundreds of those kinda micro optimisations

[eternal needle]

honestly your code isnt readable at all given that you're forcing the entire if statement on 1 line. id definitely not accept this if i saw it in a pull request

i dont really understand why you wanted to ask on enum vs bool if you were gonna choose a bool for "performance" anyways
