[polar acorn]

If you can find em, they're yours

[inland latch]

this is literally the object the debug log sent me to

[naive pawn]

hey do you by any chance have multiple rbs on that object

[swift crag]

that is impossible

[inland latch]

nope

[naive pawn]

oh yeah.

[polar acorn]

What about child objects?

[naive pawn]

GetComponent wouldn't get those

[inland latch]

also nope, but i have a collider on a child

set to trigger

[polar acorn]

Okay, so, we know at the time of the log, this object's rigidbody is not kinematic, but at the time it's drawn in the inspector, it is. Something is setting it back to kinematic. Possibly something in Update?

[wintry quarry]

What's teh movement type on the XRGrabInteractable?

[polar acorn]

Or possibly something in the XR Toolkit

[wintry quarry]

The XRGrabInteractable can and does change the kinematic state of the RB if you're in particular movement type modes

[swift crag]

That does sound plausible

[wintry quarry]

(I think)

i.e.

[inland latch]

i ctrl f and iskinematic is only referenced in xr script and the script i've showed

[wintry quarry]

I'm asking about your settings on the XRGrabInteractable component in the inspector

not your code

[inland latch]

someone else asked about my code

[inland latch]

im not saying things randomly

[polar acorn]

To be fair, I asked about the code. Since it's not set anywhere else it's probably the XR toolkit somewhere

Just wanted to make sure

[wintry quarry]

what other components are on the object, if any?

[polar acorn]

Just reiterating where we're at in the investigation. Logs cannot lie. At the time that line runs, it is properly non-kinematic. So we need to find where it's changing

[inland latch]

everything here

[polar acorn]

I think there's a setting on the "Hand" object for how it handles grabbables?

[inland latch]

uhh what script am i looking for?

and or setting

i did change some of these settings

[polar acorn]

I can't remember what it's called and I don't have any VR projects on this machine to look up, but it's in the game objects that define the "hand", where you'd specify things like what button grabs things. At least in SteamVR, I don't think I've ever used XR Toolkit without it

[polar acorn]

Man this is just different enough from SteamVR that I don't know where to look specifically.

[inland latch]

wait

that's the code that's modifying it so it seems it's setting it back to the settings when dropped

[polar acorn]

That looks promising

[inland latch]

but the setting changed after it was picked up

[polar acorn]

It could have cached the wrong value for m_WasKinematic

[inland latch]

hang on

[inland latch]

ok, fixed it, set it to false on drop not on grab

that was the solution

[burnt vapor]

Didn't expect them to even copy the comments tbh

[languid spire]

that's why I said Copy/Paste rather than AI

[burnt vapor]

Understandable yeah

[languid spire]

no way they retyped all of those comments

[echo copper]

How to add object to prefab but don't make him a child of it prefab?

or how to make child object not to following the parent object

[swift crag]

you can unparent it as you instantiate the prefab

[polar acorn]

I'm not sure what you mean by "adding" to a prefab other than making it a child

[swift crag]

I do this in my game

[polar acorn]

Ah, that, yeah

[swift crag]

I have a ragdoll system that must not be parented to the actual character (or it'd start moving itself around!)

[polar acorn]

that's basically the only way to do it

[swift crag]

During spawn, I create a new root object, reparent my entity to it, and then reparent the ragdoll system to it

(that way, I don't have a bunch of loose objects floating around in the hierarchy)

[echo copper]

okay, just unparent objects while spawning them in scene, right?

[swift crag]

indeed. you can do it in Awake so that it happens immediately

[swift crag]

I didn't want to create the new "empty root" in the prefab, since that would stop me from referencing the Entity component (which would no longer be on the root object!)

[echo copper]

wow, Fen, you're really helpful, thanks!

[crimson pike]

when it comes time to reach out to these lists for entries by name, is using a linq search going to be less than performant long term?

or should i roll everything up into a dictionary at awake

[polar acorn]

Dictionary would be faster, but Linq queries wouldn't be too bad aslong as you're not doing it like, every frame

[crimson pike]

aim is to make the SOs drag and drop via the editor but at runtime do i need the added speed via dictionary?

(cuz i'm getting non programmer on board to help)

ok, i'm just not sure how far i have to go with unity to be scalable, if its overkill is all i'm asking

yeah i dont think i'm going to be accessing this info that frequently, if anything the scripts that need their references will pull them at awake i think

[polar acorn]

It's not too far to roll them into a dictionary at the start, that seems like a reasonable optimization if you're going to regularly access them by name

[swift crag]

Dictionaries also make it more clear what's going on

I'd value that over the (marginal) performance gain

[crimson pike]

yeah its more for readability

like cinematics just represent scripted non player controlled movements and stuff, it's basically just a stage based script sequence

[snow warren]

hi

anyone needs my help

I am actually sad today and alone so i thought i could help someone with his problems

(code related only)

[woeful bridge]

another thing cuz I don't know C# very well
If I remove index 0 of a list and have a index of 1 2 3 does it automatically shift or is it just
Null, "something", "Something", "Something"

I got a weird feeling the answer is gonna annoy me cuz everything with C# seems to annoy me so far lmao

[slender nymph]

when you call Remove on a list all of the subsequent indices shift down

[woeful bridge]

Is there a way to prevent that

or should I just use a dictionary instead

[snow warren]

how can you remove index 0
as far as i know list.Length is readonly

[woeful bridge]

Can you not remove values from a list????

[slender nymph]

if you want null entries then assign null. removing an object from the list literally removes it

[snow warren]

you can but it doesnt mean it removes an entire stack from memory and marks it null
its C# you are dealing with

[woeful bridge]

I don't know C# lol I know lua I started C# 2 days ago lol

Thats why I asked

[swift crag]

that is what you are currently describing

removing values from a list

[woeful bridge]

yeah the guy above said- nvm

Ok I'll set it to null thanks

[crimson pike]

yes 1 becomes 0 automatically

[slender nymph]

also if you have no need to add or remove entries and you just want a fixed size, then just use an array

[crimson pike]

lists are basically better arrays

"managed" arrays

[swift crag]

what's the use-case here?

[woeful bridge]

well I need specifically Null, "Value", NULL, "Value"

hotbar

[slender nymph]

yeah just use an array. no need for Add/Remove methods on that

[woeful bridge]

kk

[polar acorn]

If the size is fixed, use an array. If it's variable, use a list

[crimson pike]

wait do you WANT the entries to be null?

[woeful bridge]

yes

[crimson pike]

then yeah array.

[polar acorn]

And if you want the list to contain the value null, you would need to set it specifically to null

[crimson pike]

use appropriate data structures for the job

[woeful bridge]

oh right I gotta type things

I hate types lol

ok I'll use an array thanks

[crimson pike]

lists are good when you want the collection to have convenient functionality without having to manage references/pointers

[slender nymph]

although rather than having an array of just random items that can be null, it may be better to just have an array of objects that control each specific hotbar slot and let them have a property that describes what that slot contains and let that be null

(let the property be null, not the array entry)

[woeful bridge]

[snow warren]

you can do it like this

Ints[0] = null;

foreach(int Number in Ints)
{
    if(Number != null)
    {
        //Your code comes here
    }
}```

[woeful bridge]

I'm gonna do it my way then make it better after lol

[snow warren]

this way you can set one value null

as in your case 0

and it will continue to work from 1 2 3 and so on as index

[woeful bridge]

kk

[slender nymph]

i just want to point out that value types like int cannot be null

[polar acorn]

int is not nullable. You can't set a value in that list to null

[snow warren]

is there no way to set it null

[polar acorn]

Not if it's an int

If it's an int? then yes

[woeful bridge]

I miss lua sometimes

not type checking was so nice

[snow warren]

didnt know that before

[slender nymph]

even then it's still not truly null. it's still an instance of a value type with a bool property that describes whether it is equivalent to null

[polar acorn]

As someone who regularly programs in Python and C#, no, it isn't. It's incredibly painful and if you're doing anything more complex than like, a script to compute how much of a tip to leave, you're going to do whatever it takes to enforce type checking

[snow warren]

lua is expensive for game development but for inner game functions like debug functions and other developer features in games
many people support lua
like frostbite uses lua to set directory infos of their game files and hashing tables

[woeful bridge]

As someone who has been coding in lua for 3 years I prefer it lol

[slender nymph]

once you get used to a language that has actual types you'll find it is far better.

[crimson pike]

you can also use linq to filter out the nulls

[snow warren]

yep

[polar acorn]

You'll get sent a variable as a parameter and have to spend three hours tracking down the chain of references to find the thing that created it just to know what object it even is

[woeful bridge]

I've never had that issue before

[polar acorn]

As opposed to C# where it's just like "Oh this variable is of type GameObject, you can use all the GameObject properties on it"

[crimson pike]

List<int?> Ints = new List<int?>{ 1, 13, 98, 2};

Ints[0] = null;

foreach(var Number in Ints.Where(i.HasValue))
{
        //Your code comes here
  
}

[woeful bridge]

But yeah I know why type checking is important I just don't like it

[polar acorn]

Again, can't set an int to null

[crimson pike]

fixed

[woeful bridge]

In 3 years of lua development I've never ran into the issue of tracking down a chain on refrences lol

[snow warren]

well isnt int? used to know whether a pointer is null or not?

[crimson pike]

yes

forgot the nullable

[rocky canyon]

whats the ? mean in the list type <Type>?

[slender nymph]

it's not a pointer

shorthand for Nullable<int>

[snow warren]

ok

[rocky canyon]

ahh okay.. thnky 👍

[polar acorn]

The list of type int?

As in, nullable int

[crimson pike]

all the primitives can be nullable (bool? float? int? etc)

[rocky canyon]

ya, i was thinking that was ??

[swift crag]

That's an unrelated operator

[crimson pike]

?? is just an inline null check

[swift crag]

as are ?. and !

[rocky canyon]

ya, i was getting the two confused

thats y i asked 👍 thanks guys

[polar acorn]

Other than that they involve null

[crimson pike]

! is usually just "NOT(whatever)"

[snow warren]

hey i wanted to know how these binary operators work

and <<

[crimson pike]

you can use ? a few ways, depending on if its a ternary operator or you're breaking out inline on a null

[rocky canyon]

they're bitshift operators i believe

[swift crag]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/bitwise-and-shift-operators#left-shift-operator-

[snow warren]

yea

what do they do

[crimson pike]

ok uh

[swift crag]

they shift bits

😉

[rocky canyon]

check out fen's link

[crimson pike]

its for bitwise math

[slender nymph]

until it's used as the null forgiving operator

[swift crag]

this can produce really funny code

[crimson pike]

so like, take a 4 bit int for the sake of keeping simple

[swift crag]

bool x = !true!;

[snow warren]

i saw it once in the compiler
i used many multiplication and division in my code
and then compiled it

[crimson pike]

0000 = 0
0001 = 1
0010 = 2
0011 = 3

[woeful bridge]

I can be evil and use lua unity....

[swift crag]

or maybe bool x = !!!!!!!!!!!!!!!!!!!!!!true!;

[crimson pike]

bit shifting 0010 << would make it 0100

[snow warren]

i then disassembled it and it was using bitwise operators

[crimson pike]

bitshifting it >> would make it 0001

[snow warren]

how could it be related to math

[hardy sigil]

Would that compute to true?

[swift crag]

that's a common optimization for powers of two

[crimson pike]

you probably dont need to do anything with that in unity... unless you're using bitflags

[polar acorn]

Shifts the bits of the value to the left or to the right, disregarding any values that shift "off" the number

[crimson pike]

i can't remember the last time i did bitwise operations

[swift crag]

No, false.

A prefix ! is a boolean not operator, which gives you false
A postfix ! is the null-forgiving operator, which only matters if you've configured your compiler to be strict about null-checking

[snow warren]

well for heavy binary data that can sometimes come in handy

[crimson pike]

but it involved writing drivers for a circuit board tests

[swift crag]

Shifting left by 1 doubles a number.

(an integer, that is)

[rocky canyon]

int x = 2;      // Binary: 10
int result = x << 1; // Binary: 100 (2 * 2 = 4)
Debug.Log(result); // Output: 4```
```cs
int x = 4;      // Binary: 100
int result = x >> 1; // Binary: 10 (4 / 2 = 2)
Debug.Log(result); // Output: 2```

[swift crag]

shifting a float left does funny stuff

[woeful bridge]

I had an idea then I could use a list for my hotbar slots and a array for whats in my inventory :D boom fucking big brain

[crimson pike]

theres good uses for it, usually like i said bitflag operations

[snow warren]

brain.exe not working

[crimson pike]

bitflags are like fancy optimized ways to use enum values

[rocky canyon]

i see them most commonly used w/ layers

layermasks and whatnot

[crimson pike]

you can use it for option sets for instance

[slender nymph]

if(someValue !< 69) //more code here

[polar acorn]

I like to think of them as a compressed bool[]

[crimson pike]

yeah essentially

the behavior is like that

like say you want to have a checkbox list of options for something in your UI

[rocky canyon]

knowing Binary is a really useful skill when learning about bitshifting

[swift crag]

Oh hell yeah

Bringing back the secret <-- operator

[crimson pike]

"Show Players" = 0001
"Show Terrain" = 0010
"Show Enemies" = 0100
"Show Projectiles" = 1000

[snow warren]

what does it do?

[crimson pike]

then you can use bitwise math to determine from a single integer value which of those are to be applied

its a very optimized way of handling things like that

[swift crag]

whoops, other way around

it's a trick

https://stackoverflow.com/questions/1642028/what-is-the-operator-in-c-c

[rocky canyon]

<!-- No Clue.. But this is a comment in HTML /-->

[crimson pike]

1111 would mean all of them are checked, 0000 would mean none are

[swift crag]

it's a good demonstration of how the compiler does not care about spaces, though!

God

[rocky canyon]

👀 huuh

[crimson pike]

you can use AND masking to determine if the option is selected or not like:

if (0010 & myOptionValue == 0010) //Show Terrain is selected if this is true

(and 0010 would usually be represented as an enum like MyEnum.ShowTerrain = Flags.Bit2 or whatever

or you can manually type it in as 0x01 or whatever

some of that may be slightly inaccurate i'm being hasty

[swift crag]

you'll see bitmasks when dealing with layer masks

[crimson pike]

yeah probably.

the include/exclude layers is bit masking i think (?)

[swift crag]

https://unity.huh.how/bitmasks#bitmasks-and-layermasks

check this out

[crimson pike]

at a very low level the code is all bitwise arithmetic. lots of it. if you ever study assembly have FUN

NOOP

[rocky canyon]

i'd like my language to be already constructed..
no. "Some assembly required" crap 🤪 🫠

[crimson pike]

get it? it was a comedic pause

[rocky canyon]

i did hear a rimshot in the distance..

[crimson pike]

aight, so this is the play then?

(i'm an obsessive readability nazi)

[rich ice]

i can already see the 99+ messages in the error list

[crimson pike]

0 errors 😐

[swift crag]

and why is that?

[woeful bridge]

Is there like a :GetChildren() kinda function that returns a array or list of all the children of a object?

[swift crag]

You can iterate over a transform

[crimson pike]

you can extend it yourself @woeful bridge

[swift crag]

foreach (Transform child in transform) {
  // ...
}

[woeful bridge]

I know was just curious if there was a built in way

kk

will do that I'll just make my own version

[rich ice]

(update, i just double checked, this doesn't cause a message in the error list )

[crimson pike]

i made my own convenience methods

why would it?

[woeful bridge]

womp

holy shit I just realize I can actually OOP in C#

I don't gotta do fake OOP anymore

its a Christmas miracle

[crimson pike]

my work wants "this" used anytime you're referencing a property or anything in itself, the habit stuck after 10 years

if you get errors its because of your linter settings or something

[rich ice]

to me it just seems unnecessary in most cases. from the thousands of messages i get in my error list, about names and readonly fields, i kind of assumed that would be included

[crimson pike]

thats a you problem

[rich ice]

real

[crimson pike]

the two warnings coming from some assets i downloaded are driving me nuts tho

[crimson pike]

wdym

you come from python/javascript?

[woeful bridge]

Lua doesn't have a way to OOP so you gotta fake it

[crimson pike]

lua i dont think was ever intended to be OOP

isnt it just for simple event scripting?

[woeful bridge]

luau is for game deving so

[crimson pike]

yeah i started implementing it on an old project, but it amounted to just telling sprites where to walk

[swift crag]

it's very popular as an embedded scripting system

[deft harness]

not hardly...

[crimson pike]

that was like 15 years ago tho

[woeful bridge]

yeah it doesn't support OOP but I basically just cloned refrences to kinda make my own objects

[crimson pike]

the OOP oriented stuff just used those script commands to do things in the engine

anyone remember ogre 3d?

[woeful bridge]

[crimson pike]

before we had these insanely easy to use tools like unity

[polar acorn]

Why would it? That's perfectly cromulent code

[swift crag]

hang on a second...

ah, no, wrong engine

[crimson pike]

it was purely a graphics engine

[swift crag]

I was thinking of Torque

for some reason (Marble Blast moment)

[crimson pike]

though you could find libraries to handle things like input and physics

torque sounds familiar wasn't that physics?

oh yeah i do vaguely remember looking at this a long time ago

i think ogre 3d had recently started supporting c# environments w hen i got into it. c# was still relatively young then

[rich ice]

considering the usual random stuff the messages tend to complain about. i assumed non-strictly required code would be included

which is also why i have messages disabled most of the time

[twin bolt]

I'm trying to close a door from script, using MovetowardsAngle, which works, but the door glitches when the doors rotation = 0, and the player has to push the door off of a 0 y rotation, for it to work again. How do i fix this? https://hastebin.com/share/amuboyojam.cpp

[slender nymph]

what do you mean when you say it "glitches"

[crimson pike]

That’s just code style whining at you. You can customize all of that

[wintry quarry]

You're trying to read euler angles from a Transform and do logic based on it. It's a mistake every single time. Never do this.

[twin bolt]

When the "Close Door" bool is enabled, but the door is at 0, the door jitters between 0 and 1, almost as if it is shaking, and the player has to apply force to fix it.

[twin bolt]

What would i do then?

[swift crag]

you should keep track of the angle you want and use that to compute a rotation

[wintry quarry]

keep track of the angle yourself in a float

[swift crag]

Euler angles can exhibit interesting behaviors, like suddenly changing by 90 or 180 degrees

[rich ice]

wait you can? i haven't really messed with visual studios. im still using the default settings ._.

[polar acorn]

Because the values 30, -330, and 390 are all the same angle

[twin bolt]

so read the euler angles from a transform, and set it to a float first?

[polar acorn]

and you have no idea what the inspector is going to decide to use

[swift crag]

Do not read them.

If you must recover an angle from the existing transform, consider using Vector3.SignedAngle

That lets you reliably compute an angle between two vectors, given a third reference vector

[crimson pike]

Yeah it’s either linter or code style rules or something like that

[swift crag]

Euler angles are not what Unity tracks internally

it works with Quaternions

[crimson pike]

It’s just what you set up to keep code standards consistent over a team

[swift crag]

the Euler angles it computes can abruptly change

[twin bolt]

I'm not following, so i should use Quaternion instead? If not how would i set a float, without reading the objects rotation?

[swift crag]

Store the angle that you want the door to have.

[rich ice]

i'll give it a search now and see if i can mess with it a bit. thanks for letting me know

[swift crag]

Change that angle to make the door open or close

Use the angle to compute a rotation for the door.

[twin bolt]

I am storing a float, of the Closed Rotation, which is being used in this float newYRotation = Mathf.MoveTowardsAngle(Door.transform.eulerAngles.y, ClosedRotation, 100 * Time.deltaTime);

So i shouldnt be reading euler angles

[swift crag]

Okay, so store another float for the current angle

[twin bolt]

And How would i get the current angle if this code is being executed every frame?

[swift crag]

The script decides the current angle

[wintry quarry]

Door.transform.eulerAngles.y

You need to use your own variable instead of this

[wintry quarry]

store it in a variable every time you calculate it

[swift crag]

private float angle;

public void Open() {
  angle = 90f;
}

something like that

[wintry quarry]

In fact you literally are already storing it

[swift crag]

(I presume you'd set a target angle and then move towards it)

[wintry quarry]

in a variable called newYRotation

[swift crag]

well, it's not being persisted

[wintry quarry]

just make sure to keep that around between frames - by storing it in a member/instance variable on your class.

[swift crag]

that's the thing that needs to be done

What you're doing will also break if the door isn't perfectly vertical, mind you. It'll spin on the wrong axis.

[twin bolt]

So for instance if i created a variable named "CurrentROT", would i use CurrentROT = Door.transform.euler angles.Y, every frame?

[swift crag]

No.

Again: you must not try to read transform.eulerAngles

[polar acorn]

You would never read the object's eulerAngles

[swift crag]

That's the problem. That's why your door is breaking.

Stop doing it.

[polar acorn]

You would keep track of the variable yourself

and then change the euler angles to the value you're keeping track of in code

[swift crag]

void Update() {
  currentAngle = Mathf.MoveTowardsAngle(currentAngle, targetAngle, Time.deltaTime * 90f);
}

that's it

[wintry quarry]

never no

never read the euler angles from the Transform

that's the point

[twin bolt]

So i should create the float, set the float to 90 for instance, then at the end of it being processed, feed it back into this code? ``` Door.transform.eulerAngles = new Vector3(Door.transform.eulerAngles.x, newYRotation, Door.transform.eulerAngles.z);

[wintry quarry]

you're still reading the euler angles from the transform

I would do something like this

[swift crag]

Pretend that Door.transform.eulerAngles is set-only

Do not attempt to read it.

Ever.

[polar acorn]

Do not read from Door.transform.eulerAngles

Ever.

[swift crag]

Stop trying to get it! That's why it's breaking!

[twin bolt]

Oh, you cant read eulerangles, only set?

[polar acorn]

Even when setting it, don't use its existing values

[swift crag]

You can, but you shouldn't.

[polar acorn]

You should not

[swift crag]

I don't think we're on the same page here.

We're telling you to stop trying to read the value of transform.eulerAngles because it can abruptly change in surprising ways

[twin bolt]

Okay.

[swift crag]

personally, I would prefer to do this:

door.localRotation = Quaternion.AngleAxis(angle, Vector3.up);

as the most clear way of describing what I'm doing

this also fixes several other problems, such as the door breaking when tilted

[wintry quarry]

Quaternion originalRotation;
float currentRotation = 0;
float targetRotation;

void Start() {
  originalRotation = Door.transform.rotation;
}

void OpenDoor() {
  targetRotation = 90;
}

void CloseDoor() {
  targetRotation = 0;
}

void Update() {
  currentRotation = Mathf.MoveTowards(currentRotation, targetRotation, rotationSpeed * Time.deltaTime);
  Door.transform.rotation = originalRotation * Quaternion.Euler(0, currentRotation, 0);
}```
I would do something like this @twin bolt ^

[woeful bridge]

Is the hierarchy in the same order still even when I press play?

[wintry quarry]

as long as your code doesn't rearrange it

[swift crag]

my rule of thumb is that anything that involves manipulating individual components of a vector is wrong

[woeful bridge]

holy shit thats amazing

kk

[swift crag]

such as trying to put euler angles back together component-by-component

[woeful bridge]

I think I'm gonna finish coding a hotbar and picking up stuff today then I'll probably show my code for advice since I'm doing whats easy for me rn

[twin bolt]

Okay, i'll try it.

[plucky kernel]

hope I can get some help with this. I had this question stored somewhere else on my computer

I can't figure out how and where to use LookRotation, in order to get my car to look like it's attached to the terrain (basically like Big Rigs). This is for a school project and my professor had us copy paste like 90% of the code I linked. My professor told me that I should try to use LookRotation. I looked at the documentation for it and I think I understand how to use it? I used the car's velocity vector as the Forwards parameter and the terrain normal from a Raycast as the Upwards parameter. However, I'm really lost on where and what this LookRotation should be added to. The car moves and rotates with the rBody.Move method at the bottom of the FixedUpdate method, so I decided that it should happen before that's called. I set the vehicle's transform.rotation to the LookRotation and it doesn't fully work as intended.

The car rotates with the terrain in the Y and Z axis, but no rotation ever happens in the X axis. When you turn, the car completely stops and turns in place and once let go, it continues in its new direction with the same velocity. It sometimes gets stuck on terrain, which only happens when I use LookRotation (like everything else I'm listing). Letting go of the gas decelerates the car drastically. When it comes to a complete stop, the LookRotation viewing vector returns zero and the rotation resets completely to 0. Lastly, the car doesn't move smoothly, but the frames aren't dropping. If I were to multiply transform.rotation by the LookRotation, then the car rotates super fast, in place, in the direction of player input (going forward, turning, and going backwards). Also, in the rBody.Move method, removing " * turning" in the last parameter doesn't change anything. I don't know how many of those issues are ones that I should've shared, but I'm just, very lost on how I should use LookRotation. Does anyone know what I'm doing wrong or any logic I'm not understanding? Here's the code: https://hastebin.com/share/ukejobujiv.csharp

[woeful bridge]

Is there like a .changed event for lists/arrays?

I tried googling but nothing was super helpful

[polar acorn]

Not unless you make one

[wintry quarry]

I used the car's velocity vector as the Forwards parameter and the terrain normal from a Raycast as the Upwards parameter.
Sounds about right
No - you could make wrappers for it

[woeful bridge]

womp

for now for simplicity sake even if its not performant I'm just gonna check every frame then make it better after

[crimson pike]

Events not hard to make just make your own

[plucky kernel]

so maybe I'm just using it in the wrong spot?

[wintry quarry]

if (Vector3.Dot(transform.forward, velocity) < 0 && movementDirection.x > 0)
{
    turning.y = -turning.y;
}
// Left reverse turning
else if (Vector3.Dot(transform.forward, velocity) < 0 && movementDirection.x < 0)
{
    turning.y *= -1;
}```

uhhh this is bad

[slender nymph]

your code is what changes the collection, so instead of just checking each frame if it is different (which is likely not going to work the way you think it is), just do what you wanted to do on change when you change it

[plucky kernel]

oh I know, but it works somehow

[wintry quarry]

you shouldn't be touching .y of a quaternion

[woeful bridge]

I guess

[plucky kernel]

unless it's interfering with the LookRotation

[woeful bridge]

I haven't figured out cross script communication yet so I rather just get something functional rn then work on learning more

I wanna get the bare bone basics down checking every frame will do what I want tho all be it horribly not optimal

[slender nymph]

https://unity.huh.how/references

[slender nymph]

how do you plan to check this though

[woeful bridge]

..looping through an array all its doing is updating a UI

[crimson pike]

Yeah don’t do that

[wintry quarry]

You're also double-factoring in the turning quaternion
Once here:

velocity = turning * velocity;```
And again here:
```cs
rBody.Move(position + velocity * Time.fixedDeltaTime, transform.rotation * turning);

you're also modifying the Transform of a Rigidbody directly, which isn't good

[twin bolt]

Okay I intergrated what you gave into my script, and although it works, it just snaps there, it doesnt rotate over frames: ``` if (CloseDoor)
{
CurrentRotation = Mathf.MoveTowards(CurrentRotation, newYRotation, 1 * Time.deltaTime);

        Door.transform.rotation = StartRotation * Quaternion.Euler(0, CurrentRotation, 0);
    }```

[woeful bridge]

yall I'm just learning the engine I don't need optimized code just yet lemme make my own mistakes I just asked if there was a .changed lol

[slender nymph]

we're trying to help you learn, but you're literally refusing to listen to the advice that will make things easier for you

[wintry quarry]

look at my code example. The rotation stuff is not inside an if statement and shouldn't be

[plucky kernel]

wait nvm, I just tested reversing with the LookRotation and yeah it's really not good

[crimson pike]

It’s not even really about optimization what you’re doing is called polling

[woeful bridge]

I learn better just logicing stuff out on my own

[crimson pike]

It’s got a lot of drawbacks to it especially with a black box engine

[woeful bridge]

I know lol thats why I'm gonna code it to functioning then change it

[plucky kernel]

for some reason removing that "* turning" in the Move method doesn't change anything

[woeful bridge]

Its like 10 lines of code lol I'll be ok

[crimson pike]

Aight good luck 👍

[woeful bridge]

I'll work on events after tho to make it better

[twin bolt]

I know, thats for my script, its just a bool that closes the door when triggered: private void OnTriggerEnter(Collider other) { if (other.tag == "Player") { CloseDoor = true; Debug.Log("Closing"); GetComponent<BoxCollider>().enabled = false; } }

[crimson pike]

It’s probably easier to just use events right out the box tbh than what you’re looking to do

Events just take one event declaration and something to subscribe to it with its callback. It’s native c# stuff

[plucky kernel]

okay, what should I do instead? The only code I've added is the Reverse Turning logic and the LookRotation statement that I'm unsure of

the rest of the code is from my professor

which he had us use

[wintry quarry]

Hard to say without seeing the rest of the code then like where is newYRotation written

[twin bolt]

newYRotation is a public float variable i made, which i'm going to set (in the inspector), for every door. In this case its set to 90 in the inspector.

[slender nymph]

you should take another look at my suggestion from earlier where your store an array of objects that directly control each hotbar element where those contain the information about what is stored in each element rather than having an array that directly stores what is contained in each hotbar element.
basically this:

class Hotbar
{
  Item item {get; set;}
}

Hotbar[] hotbarElements;

your hotbar class could then have an event that is fired when its item property is modified, then you won't need to loop through the array each frame, you will be able to hook up the UI objects directly to the Hotbar objects so that only the relevant objects are modified each frame instead of all of them

[wintry quarry]

So it's like "closedAngle" or something?

[twin bolt]

Yes, these doors are only meant to go 1 way, back to being closed.

[woeful bridge]

So a getter and setter basically?

[slender nymph]

that's what a property is, yes

[crimson pike]

@woeful bridge

private int?[] list;

public event EventHandler ArrayChanged;

public void DoSomething() {
    list[0] = null;
    this.ArrayChanged?.Invoke(this, null);
}

thats on the event source

[wintry quarry]

This code is in Update? Where is it?

Maybe show the full script

[crimson pike]

public void Awake() {
    theObjectWithTheEventOnIt.ArrayChanged += this.OnArrayChange;
}

private void OnArrayChanged(object sender, EventArgs args) 
{
    // respond to event here
}

just examples

how to define and trigger event with no special pattern, and how to subscribe (respectively)

[twin bolt]

https://www.toptal.com/developers/hastebin

[wintry quarry]

That's the blank hastebin link 😛

[crimson pike]

also null check this.ArrayChanged first too, in case no subscriptions have been made

[twin bolt]

Oh Sorry

[swift crag]

That's a nice place to use ?.

[crimson pike]

yeah

[swift crag]

ArrayChanged?.Invoke

also, I generally don't bother using EventHandler

[crimson pike]

yeah either way works

[twin bolt]

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

[crimson pike]

i'm just keeping it simple

[swift crag]

most of my events are just System.Actions

zero arguments, no return value, no brakes

yeehaw

[woeful bridge]

Honestly my biggest issue rn is UI is like 100x's harder on unity than my old engine I'm trying to figure that out I might just stop coding for a little and look at a tutrorial for an hour

[crimson pike]

not trying to confuse him with lambda stuff

[slender nymph]

you don't need any lambdas with System.Action, it's just another delegate like EventHandler

[crimson pike]

but yeah i love me lambdas

[swift crag]

neither of these involve anonymous functions

ye

[crimson pike]

true

[swift crag]

I found EventHandler to be extremely confusing, actually

I thought it was somehow "special"

as in, it was necessary to use event

[crimson pike]

its kind of outdated yeah since they introduced Func/Action

[swift crag]

event is literally just a way to stop other types from invoking or setting your delegate type

[wintry quarry]

CurrentRotation should be private and it should start at 0

[crimson pike]

theres a few ways to go about it, thats one

[woeful bridge]

If i'm gonna be honest my major struggle in C# which is why I'm avoiding doing anything I consider advance rn is I'm having a really hard type getting my python/lua habits to go away

[twin bolt]

Fixed that, but it still snaps there.

[woeful bridge]

I'm hardly able to even use camel case rn without fucking up 300 times lmao

[crimson pike]

        private int?[] list;

        public event Action ArrayChanged;

        public void Awake() {
            list[0] = null;
            this.ArrayChanged();
        }

also fine

[woeful bridge]

I might just learn C# first then go back into unity

I know basic C# cuz of java and shit

[slender nymph]

this is 100% the way to do it if you want to fully understand what's going on in your code

[crimson pike]

if you dont already know c# pretty well unity is just a buttload of extra academics to confuse yourself with

[woeful bridge]

I mean I understand C# just not on the level I do lua

[crimson pike]

although i did learn c# pretty well by using Ogre3d

[woeful bridge]

Which is the issue cuz I keep mixing them up

[wintry quarry]

you sure there's no other components or anything? I'm not sure how that would happen 🤔
Can you Debug.Log currentRotation over time?

[woeful bridge]

I've done like a java and basic C# from college class but I learn better going into it and learning it myself through doing things which is why I'm doing unity rn

[crimson pike]

if anything use the unity project as the goal and anytime you dont know how to accomplish something natively in c# just study it and make a small project to get used to it

although unity does introduce some quirky rules to it all too, so maybe create a side console project for experimentation

[woeful bridge]

yeah a lot of engines do that lmao

godot make python but... quirky roblox made luau

[swift crag]

note that you should use MoveTowardsAngle here, not MoveTowards, but that wouldn't cause it to instantly close

[crimson pike]

you already got some foundation, thats all you need to learn

[mystic lark]

is it better if i dont have many if statements cuz i finished a simple game with like only 5-6 ifs

[crimson pike]

this UI part seems like a good introduction to events and Action/Func pipeline

if you want to make listeners and stuff

[woeful bridge]

ye though UI itself on unity is driving me fucking insane

roblox all I had to do to scale UI was just type in 0, .5, 0, .5 and boom shit scales on every reso unity ui has so much extra shit that its huring my brain lmao

[twin bolt]

The debug, says 0, until the "closeDoor" bool is enabled, then it starts saying -0.0197337

[swift crag]

You should have a look at https://docs.unity3d.com/Packages/com.unity.ugui@2.0/manual/UIBasicLayout.html

I struggled with UI for a while until I read how this works (along with Auto Layout)

[woeful bridge]

Is auto layout the grid layout stuff

[swift crag]

this implies that CurrentRotation is getting set to 0 every frame

[swift crag]

more generally, it's all of the Layout Group components

[woeful bridge]

Yeah funny enough roblox taught me that and I was in a vc with another unity dev and he went woah wtf

lmfao

[swift crag]

It allows for your UI to grow and shrink based on the space requested by child objects

[crimson pike]

i haven't messed with the UI tools yet

[woeful bridge]

the stuff in that link is the stuff I need to learn so thats awesome thanks

[swift crag]

The problem is that the default UI objects (created in the GameObject menu) are not auto layout friendly

[woeful bridge]

Though does it matter i'm using that one pro ui thingy

[swift crag]

They all collapse into 0x0 points when put under a layout group that controls child size

[woeful bridge]

this shit

TMP

that stuff

Yeah I figured out layouts like instantly its just.. scaling that doesn't function lmao

[slender nymph]

the layout of your objects like the TMP_Text object will be controlled by the layout group objects

[woeful bridge]

Though my biggest issue rn is just time
I'm trying to juggle doing two engines at the same time and its really hard to do that lmao

I might hire some devs to work on my roblox side of things so I can focus more on unity

I didn't think it be this hard to juggle engines

[wintry quarry]

the same number over and over?

[twin bolt]

When i set the NewYRotation to 90, then the debug gives -90, at the beginning, and in half of a seconf it changes to -89

[wintry quarry]

My thinking is this stuff:

       if (CloseDoor == true && !Door.GetComponent<DoorStats>().open)
        {
            CloseDoor = false;

            if (LockDoor)
            {
                Door.GetComponent<DoorStats>().locked = true;
            }
        }``` is making it stop after one frame

can you comment that out for the moment

[twin bolt]

I'll comment it out

[wintry quarry]

it should start at 0

why isn't it starting at 0?

Are you sure you made CurrentRotation private?

[twin bolt]

It is at 0, i just changed it for testing

[twin bolt]

Okay after deleting that stuff, i got something new, the door snaps to the closed rotation, but now slowly rotates the x to -90

[wintry quarry]

Are you changing its rotation after Start?

Maybe in the DoorStats script?

[twin bolt]

Well the player opens the door first, to get it to the 0 rotation, then walking into the trigger, starts this function.

[wintry quarry]

I see so that's the problem

[twin bolt]

Let me check

[wintry quarry]

you need to record the rotation after it opens

My original code example assumed it starts closed

And your code kind of assumes it starts out open now

[twin bolt]

Sorry, this code is meant to close the door once its open.

So i'll fetch the doors rotation at ontriggerenter

[wintry quarry]

Basically the only thing that needs to change is instead of doing StartRotation = Door.transform.rotation; in Start(), that code needs to happen as soon as the door finishes opening

[wintry quarry]

ah yeah that could work too actually

moving that to OnTriggerEnter

[twin bolt]

Okay, no more glitching, but now for some reason the doors x is rotating 🤣

[crimson pike]

real briefly, what are Playables for?

[wintry quarry]

maybe some kind of scaling issue?

[wintry quarry]

They're for Timeline

https://docs.unity3d.com/Packages/com.unity.timeline@1.8/manual/index.html\

If you're talking about what I think you're talking about

[twin bolt]

I dont think its scaling, the y isn't rotating at all, only the x, almost as if thats what i'm setting it to rotate.

[crimson pike]

broken link.

[wintry quarry]

https://docs.unity3d.com/Packages/com.unity.timeline@1.8/manual/playable-director.html

this work?

[crimson pike]

yea thanks

so its like cutscenes? or can it do game-time events too?

[wintry quarry]

Either one

[twin bolt]

Here is the new script: https://hastebin.com/share/naqoliyoqa.csharp

[wintry quarry]

mainly intended for cutscenes I think? Anything where you want to set up a scripted sequence of events involving a bunch of different stuff like audio, camera movements, animations, etc.

[crimson pike]

oh cool. i guess my approach is redundant then

i was gonna use SOs to create pre-scripted sequence pieces

[wintry quarry]

I've never actually used Timeline so I have no idea how good or useful it is

[crimson pike]

checking a tutorial to see if its overkill for what i want to do with it

[polar acorn]

If you've ever made an animation solely for the purposes of calling Animation Events at specific times - it's that, but not ass to actually work with

[wintry quarry]

What's the starting rotation of the door

[crimson pike]

so long term i needed a way to expose cinematic sequence construction to non programmers for short "cutscenes" during gameplay

i was just gonna make SO pieces for like (MoveToDestination) or (PlayAnimState), preconstructed actions and stuff

[polar acorn]

Timeline and cinemachine are a perfect fit for that

[crimson pike]

and the non dev would just drag and drop those sub-units into a list

and configure them

[polar acorn]

You can create cameras for specific compositions and plan out cuts and whatnot just like you were editing video

[crimson pike]

yeah i just need them to be able to script short cinematic interactions after enemy waves or between map nodes* without breaking the game flow or needing to know unity too deeply

its just a simple shmup format

[twin bolt]

-90

[humble forum]

have the script player wich has money how can i easily show this as ui on the screen?

[polar acorn]

Put a script on your UI element that reads that value and updates the text

[humble forum]

for now it is just a variable int that gets read

[sweet mica]

I can't get the GameOver to appear once the bird hits a pipe :(

[wintry quarry]

on which axis?

and does it have a paernt?

[wintry quarry]

Is the code running? Check with Debug.Log
Also check the console for errors

[sweet mica]

No console errors, what do you mean by Dubug.Log?

[wintry quarry]

I mean add Debug.Log to your code so you can tell that it's actually running

e.g. put this inside OnCollisionEnter2D:

Debug.Log("Collision detected!");```

[sweet mica]

Does that go in pipescript or birdscript?

[crimson pike]

ok so maybe advanced question?

[sweet mica]

Yeah i have that on both

[wintry quarry]

THe only one you showed

[crimson pike]

is that possible to pull off in the editor?

[sweet mica]

I showed both lol

[wintry quarry]

What do you mean exactly

showing the destination when Move is selected?

[crimson pike]

i have a concept in mind

[wintry quarry]

No you showed BirdScript and LogicScript

not pipe

[crimson pike]

basically i can create sub classes of the CinematicAction with different parameters available

[polar acorn]

You showed two scripts. One of which has OnCollisionEnter2D

[sweet mica]

Oh right

[crimson pike]

like Move would just be to a hard set vector, MoveToObject would allow a game object transform

all contained in a scriptable object that the user can pick a set of predefined cinematic action scripts to run in sequence

[wintry quarry]

I would just put all the fields on the struct or class and conditionally render them with NaughtyAttributes

[crimson pike]

yeah that sounds like what im looking for

google time

[twin bolt]

The Door is on 0, -90, 90. It has a parent, but the parent hasn't been scaled, so there is no warping.

[wintry quarry]

https://dbrizov.github.io/na-docs/attributes/meta_attributes/show_hide_if.html

[wintry quarry]

That's why - it's starting out rotated weirdly

so due to gimbal lock you will get weird euler values in the rotation

[sweet mica]

So its detecting the collision

[wintry quarry]

is it visually rotating incorrectly?

[wintry quarry]

Ok then the code is presumably working fine

[crimson pike]

[wintry quarry]

Did you install the NaughtyAttributes package?

[crimson pike]

oh its a library?

[wintry quarry]

yes

[twin bolt]

YEs, and in the inspector, it shows the x value is gradually rotating instead of the y.

[crimson pike]

kk

[wintry quarry]

You'd have to show how it's oriented and everything

and which way the model is oriented

[crimson pike]

bloody sweet thx m8

[ocean loom]

I am working on a portal for a project, and i would like to add a system where it takes the velocity at which u enter a portal, and exits u out the other side with the same velocity. However i am to get the rigidbody component. Any ideas on how i could implement this?

[rich ice]

what order of operations do math functions follow? they dont seem to follow the usual BODMAS order (or whatever shorthand you have in your country)

[polar acorn]

You should be writing math in such a way that the order doesn't matter

5 * 5 + 5 is bad math. Use (5 * 5) + 5 or 5 * (5 + 5) instead

[rich ice]

i am, visual studios just keeps reminding me that some brackets are useless. usually i just remove themm but it'd be nice to know why

[humble forum]

why does the size change when going full screen?

[polar acorn]

If you need to get a component, GetComponent is usually your go-to

ive tried that, but it seems to not like it For some reason. Maybe because its a hashset 🤔 .

[ocean loom]

is there an alternative?

[polar acorn]

What are you calling GetComponent on

[ocean loom]

portalObjects

[polar acorn]

Yes that's a hash set. Hash sets do not have components

You are going to have to tell it which object you want to get the rigidbody from

[sweet mica]

So do I take my issue to unity talk? Since it's not a code issue?

[humble forum]

digiholic?

[ocean loom]

how do i get component from any rigid body which collides?

[polar acorn]

Call GetComponent on it

[ocean loom]

ahhh okay okay, i think i understand now. Thanks alot!

[cosmic dagger]

The size of what exactly: the screen, the sprites?

[rich ice]

update: just searched to double check. turns out that visual studios was complaining about the brackets for a completely different reason

[humble forum]

the text on the screen

like it doesn t adjust

[crimson pike]

huh, ok so... it only works as a script component/monobehavior. as a plain old custom class it doesn't seem to know how to evaluate it

[wintry quarry]

It's basically just something like:

Quaternion diff = exitPortalTransform.rotation * Quaternion.Inverse(originPortalTransform.rotation);
Vector3 newVelocity = diff * oldVelocity;```

[cosmic dagger]

What text, I don't see any. How were we supposed to know you meant that?

[wintry quarry]

It should work on any serializable class

[humble forum]

cuz i talked with him aboutit before

here it is smaller

[crimson pike]

it works on an independent game object as a monobehavior component though

[cosmic dagger]

Probably because the screen size is different (changes). It depends how your canvas is setup for scaling . . .

[wintry quarry]

hmm maybe I'm wrong

[humble forum]

but why doesn t it adjust automatically unity is weird compared to ue5

[wintry quarry]

But yeah it's possible to do with a custom editor

[crimson pike]

yeah found a 2019 thread saying it can't nest

[wintry quarry]

was just hoping naughty would work because it's easier

[crimson pike]

wonder if therse an alternative

[polar acorn]

Did you tell it to scale up for different screen sizes

[wintry quarry]

THere's Odin which is paid, or writing your own which is annoying

[twin bolt]

Here is the video of whats happening @wintry quarry

[wintry quarry]

I always use ChatGPT to help write custom editors

[wintry quarry]

Yeah I saw - can you show it in scene view with global and local rotations showing?
Your game isn't using a nontraditional world axis or something is it?

[humble forum]

no but why can t it adjust by default?

[polar acorn]

Because what if you don't want it to scale up with screen size

Then you'd be asking why it did that by default instead

One of the options has to be default

[humble forum]

then you change it why not just keep that at default would make sense imo

[polar acorn]

Scale with Screen Size just happens to not be the one they picked

[humble forum]

yeah but why unlogical

[polar acorn]

Just because it's the one you want doesn't mean it's the correct option

They have not yet invented mind-reading, so it doesn't do things unless you actually tell it to

[humble forum]

but why n=wouldn t you wanna scale the size with the screen seems like the normal option ue 5 handles this better im sure

[crimson pike]

oh yeah found it. i can make my own hide/show attribute https://www.brechtos.com/hiding-or-disabling-inspector-properties-using-propertydrawers-within-unity-5/

[humble forum]

anyway guess i will know know unity is the neighbour kid you don t wanna play with ig

[polar acorn]

Because it is exactly as logical to have "Constant Pixel Size" as the default

There isn't a "right" answer

[humble forum]

why not if people download it they will have different screen sizes?

[polar acorn]

Because you could very well be designing your UI around specific pixel counts and not screen percentages

Bigger screens might want to just have more space between elements, not bigger elements

[humble forum]

what i can t post a gif fine lol yeah get the point a bit not agreeing with their idea tho thank you for the explanation 🙂 ❤️

Hi can anyone help me? I have input system on player but for no reason it was working until I deleted files in project due to the conflict in uvsc and then I dowloaded from repository. When I Debug.Log() it will show the right reference but the input actions still not working at all

any idea?

[snow warren]

See if your input system is in the scene

[sleek notch]

wdym? I have linked in my player

[snow warren]

As an input system script in some gameobject right?

[sleek notch]

yes

It worked well

[snow warren]

It should work then

[sleek notch]

until now. I have the latest save in my project but for no reason when I downloaded back again it just doesn't work

[snow warren]

Reopen unity

[sleek notch]

I have deleted and downloaded it again

wait

nope

nothing

[snow warren]

Ok

How about using the new input system

Open package manager and download the new input system by unity

It should fix the problem

[sleek notch]

how

I have got the latest version

[snow warren]

I am going out of idea

[sleek notch]

I'm too. Idk when I Debug.Log the input action in script it shows Player/Move

[snow warren]

The input is always ok

[sleek notch]

But the ReadValue reads 0, 0

[snow warren]

Show me your input system in inspector

[sleek notch]

this?

Probably I will try to create new Input System Actions an link as it was

[snow warren]

Let's see

What files did you delete to have such an impact

Name?

[sleek notch]

I havent deleted anything? I don't fully understand you

[snow warren]

Here

You said it yourself

[sleek notch]

I deleted whole project to just link new one from unity repository

because there were some conflicts

[snow warren]

I can't help with this one
Try to port over because unity uses a lot of player settings
Any of them could impact your input system

Create a new unity project and simply copy your assets folder to the new project

[sleek notch]

I had same issue on school pc. Same unity editor version. It wasn't working until my teacher downloaded on visual studio the unity extention

idk what it would cause

I have deleted joystick input in input action because I just want keyboard only

[snow warren]

[sleek notch]

Oh well. I have created new Input system and created new move action and it works. Probably someting went wrong with the auto created when you create new project on unity 6

idk

[snow warren]

Idk

Happens sometimes

Happened to me once but not with input system

But with ui scroll scripts

[sleek notch]

yeah. Unity went wrong second time for me. It happens sometimes

So im looking to make a card game I already have the ful layout of the game even a prototype in person that i made. Im wanting to make this on unity to post in the google play store once finished, but im stuck on the coding....

What would be the best way to make a card class that has different types of cards

Trick Cards- do nothing except when played the next player has to play the same trick card or they lose a health letter

Obstacle Card- this card skips the next player.

Recovery Cards - this card recovers health if they have the certain cards to throw in the discard pile.

Special cards - these cards are handed out at the beginning and don't go in the normal deck they draw from can only be played once

[teal viper]

Inheritance. Or maybe just separate classes, possibly implementing the same interface.

[floral wren]

Composition.

Something like that

public class Card : Monobehaviour 
{
  [SerializeReference] private List<CardEffect> effects;

  public void Play()
  {
    foreach(CardEffect effect in effects.OfType<IPlayableCardEffect>())
      effect.Play();
  }

  public bool TryGetEffect<T>(out T effect) {...}
}

public abstract class CardEffect 
{
}

public interface IPlayableCardEffect 
{
  public void Play();
}

public class TrickCards : CardEffect, PlayableCardEffect
{
  public void Play() { ... }
}

public class SpecialCardEffect : CardEffect
{

}

[upper forge]

so if i did seperate classes i would just add the different scripts to the corrosponding card so each card would have different scripts on them?

[upper forge]

this is a little confusing to me lol.... :/

[teal viper]

Yes.

[upper forge]

okay and each card class have the functions for what the card does and then in the game manager class I would call the functions in there according to the rules of the game

[teal viper]

Yes

[upper forge]

once i do that how would i go about creating the deck with the different cards?

[teal viper]

If your cards are prefabs, just instantiate them and to a list or something 🤷‍♂️

[crimson pike]

Definitely break the different classes into their own files

[verbal dome]

It's in one snippet obviously for demo purposes

[teal viper]

Most performance costs/optimizations come from the code logic, not language features. Though, some features might be more expensive.
Keeping the code as simple as possible is usually a good approach

[barren wing]

Yeah. I hear don't use LINQ for performance, just keep it to for loops etc.

[slender nymph]

theoretically you already have a good understanding of how the language itself works and would just need to know about what has been added to the language rather than needing to learn from the beginning. you can check out this page to see what has been added to the language. keep in mind that unity also only uses c# 9 at the moment (and some features aren't supported)

[barren wing]

Oh, good. I thought it was C# 8 earlier. Good to know.

[slender nymph]

well 2020 is c# 8 i believe, but 2021+ uses c# 9

[cosmic dagger]

i feel like anything added after C# 5.0 or so is just syntatic sugar. if you use anything that's verbose or old, anyone hear will point out a better or newer way to do it . . .

[crimson pike]

Wait what

[slender nymph]

that's a common suggestion, though LINQ has really gotten quite performant in recent years and really shouldn't impact performance much compared to looping yourself

[barren wing]

LINQ is expensive, I've read. I've never used it.

[cosmic dagger]

typically, using LINQ adds garbage, so most devs avoid it, unless necessary . . .

[barren wing]

Yeah, and PLINQ helped, I'm sure.

[crimson pike]

I can understand in update

[cosmic dagger]

true, it depends where and how often the method using it is called . . .

[crimson pike]

the nice thing about linq was always the fact it didn’t resolve the enumerators until they were actually utilized

It’s super nice for readability anyway. I made a whole bunch of extension methods using linq to organize gameObject collections

But mostly in start/awake never in updates

[cosmic dagger]

most people forget that about enumerables. creating or using a list computes it upfront, even when not needed . . .

[crimson pike]

you can always resolve with ToList or any other To

Force resolve* definitely ran that gauntlet enough times

It’s really more useful for web applications. But yeah in a game environment I’d keep it out of the render loop

[barren wing]

Yeah, I agree.

[gentle stratus]

running into a real weird bug where whenever an enemy moves backward when i shoot at them, what kind of interaction could cause this

[crimson pike]

We’re at a point where platforms really aren’t sweating a little code bloat anymore.

[slender nymph]

see #854851968446365696 for what to include when asking for help

[gentle stratus]

ok ill edit it with code

[crimson pike]

These things might’ve been concerning in like early 2000s but your average home pc and modern consoles have a lot more ram and processing power now

[gentle bone]

i think linq is in some cases even more efficent than some beginners workaround coding

[gentle stratus]

https://paste.mod.gg/jecqwmpqcpte/0 the move script of the projectile fired at the enemy

https://paste.mod.gg/qvzzsyeljfhj/0 the move script of the enemy

[crimson pike]

I wouldn’t sweat it unless you’re observing some real performance problems and need every optimization you can scrounge. Keep expensive calls out of frequent calls and pre initialize everything that might be expensive to retrieve in an update call

[slender nymph]

fun fact, but you could have added both of those files in one link with that site. that's what the [+] button is for next to the file name tab

[gentle stratus]

oh i didnt know that

[nimble apex]

will nullable UnityAction gives error when u invoke it ?

onInputValidated?.Invoke(...);```

if its null

or it will ignore and bypass

cuz i dont want the error

[slender nymph]

1. it's aleady nullable because delegates are reference types
2. why would it throw when you're explicitly null checking here?

[nimble apex]

make sense

ty👍

[slender nymph]

so i don't see anything specific that would cause the object to move backwards, are you certain it isn't like an animation causing it or some other code?

[gentle stratus]

uhhh the animation should make it run in place

thinking of any other movement script but idt theres any

[slender nymph]

also there are a few things in there i would really recommend changing, like the fact that you are relying on specific child objects
also this transform.TransformDirection(Vector3.forward) is just silly, just use transform.forward

[crimson pike]

It will pass

[gentle stratus]

theres the patrol movement script that the enemies have but it shouldnt run that if its chasing the player

[slender nymph]

have you actually confirmed it isn't still in that state or that it isn't still running at the time this happens? because the state you've shown should animate it, right? but it was very clearly not in the animation until way after it had moved backwards

[crimson pike]

A ? Next to a nullable entry is literally telling the compiler to put an if (thisthing != null) continue

[cosmic dagger]

have you checked and tested this?

[gentle stratus]

yeah i have it debug log what state its in and it always prints 2 (chasing) instead of 1 (patrolling)

[crimson pike]

You can also trail any inline declaration using ? With ?? At the end to default to that result instead too

[gentle stratus]

yeah thats true the animations are kinda screwed up i have to fix that

[crimson pike]

I.e onInputValidated?.invoke(..) ?? OrAnotherMethod()

Iirc?

[cosmic dagger]

i just started looking at this and you're using AddForce in Update which is incorrect. this should be in FixedUpdate since you're using the default force mode . . .

[gentle stratus]

whats the diff between update and fixedupdate

[crimson pike]

Fixedupdate is per physics calculation frame

[slender nymph]

update runs each frame, fixedupdate runs at a fixed timestep that is in time with the physics updating

[crimson pike]

Update is per frame as fast as your pc can render or at the target max frame rate

[gentle stratus]

also i noticed that the enemy only moves weirdly when the projectile is not homing on an enemy

[cosmic dagger]

FixedUpdate is used for physics calculations and interactions . . .

[gentle stratus]

also wdym by default force mode

[slender nymph]

also this is not valid, can't use ?? with methods that return void (like a delegate's Invoke method)

[gentle stratus]

do you mean the parameters of the addforce line

[crimson pike]

Yeah I’m not as my desk to validate that but I remember you can use return value methods in that way.

[slender nymph]

yes, it can be used with objects that could be null

[crimson pike]

I could’ve sworn you could break out any inline references to a void method too but meh

Oh wait yeah ?? Is more like (if the prior result is null, do the trailing result)

[cosmic dagger]

AddForce has an optional ForceMode as the second parameter. if not assigned, it uses the default ForceMode.Force . . .

[crimson pike]

And ? Returns null by default if it can’t dereference

[gentle stratus]

ic

[crimson pike]

It’s just shorthand (x != null) ? LeadingThing() : trailingThing()

[gentle stratus]

ok after a bunch of testing ive found that somehow the enemy is just repelled by the projectile in general

i stopped the projectile from moving on its own and when its between me and the enemy the enemy doesnt move or moves backward

but when i get in front of it the enemy chases me again

[slender nymph]

the enemy checks if it has line of sight with the player in order to move while in that chase state you showed earlier. but that wouldn't allow it to move backwards

[gentle stratus]

yeah thats what i was confused by

[cosmic dagger]

@gentle stratus there is no need for GameObject enemy = collider.gameObject;. you only do this to call GetComponentInParent or GetComponentInChildren which you can do from collider.GetComponentInXXX

Pro-Tip: there is never a need to have a GameObject variable . . .

[gentle stratus]

it would make sense for the first part bc the projectile spawns near my head so ig its blocking a raycast

oh ok

[gentle stratus]

so presumably id have to use a mask to discount the projectile for the enemy

[slender nymph]

yes

[gentle stratus]

ok ty

[cosmic dagger]

also, you discard to returned bool value from Physics.Raycast. you don't check if the raycast hits something (a collider) or if hit.collider is true (an object was hit) before comparing the collider's tag . . .

[gentle stratus]

thats true but when i print out the results of the raycast it returns true whether or not there is a projectile between me and the enemy

and yet the enemy is still stuck

so maybe its not the raycast

[slender nymph]

like i pointed out before, if the raycast does not hit the player the enemy will not move toward it. so you need to make sure to filter out the projectiles using a layermask if you do not want the projectiles to affect it.
the raycast will likely always return true because it is infinitely long so it's likely going to hit your scene boundaries (like walls and stuff) if it doesn't hit the player, but it is still good practice to actually verify it hit something because what if you decide to add a hole in the wall or something that can be seen through but has no collider? your enemy may shoot its raycast out that hole and end up with NREs spamming the console

[cosmic dagger]

if you want the direction to be the forward-facing direction of the enemy, you can just use transform.forward instead of having to convert the world forward direction to the transform's . . .

i don't think you created a LayerMask and added the projectile to the layermask to filter it out, like boxfriend suggested . . .

[gentle stratus]

i added the layermask but i did forget that raycasts go forever

[cosmic dagger]

the default is 100 units. that's pretty big . . .

[slender nymph]

there is a parameter to set a limited range if you don't want an infinitely long

[cosmic dagger]

sorry, it's infinity ♾️, not 100 . . .

[gentle stratus]

alright so as long as i set it to the radius of the player detection sphere i should be good in theory

[stuck field]

Quite a few times you would need a gameobject variable, like enabling/disabling an object directly, using another objects name, so on, in these scenarios, a variable would prevent calling GameObject.Find() every frame/whatever you need, but in the case you stated, there is no need, but there are cases you would need one (This is assuming you aren't just going to use Transform variables or something then use .gameObject, if you need a gameobject and only a gameobject, it would be best to just use a gameobject variable rather than something like transform.gameobject)

[cosmic dagger]

yes, there are a few instances like (de)activating an object, or using it for a prefab variable (use the class type instead) but you can access the gameObject property from any MonoBehaviour instance. there is no need to create a field itself to store the GameObject . . .

[stuck field]

Yeah, that's why I specified "another object", no need to store itself, but others, there is a need

[gentle stratus]

ok now the enemies just never move towards me

bool lineOfSight = Physics.Raycast(eyeLine.transform.position, transform.forward, out RaycastHit hit, enemyStats.stats[StatNames.SightRadius], 1 << 7);
Debug.Log(transform.name + ": " + lineOfSight);
if (hit.collider != null && (hit.collider.CompareTag("Player") || (hit.collider.transform.parent != null && hit.collider.transform.parent.CompareTag("Player")))) {
    if (!dying) controller.SimpleMove(enemyStats.stats[StatNames.Speed] * transform.forward);
}```
does this look right or did i do something wrong

[ivory bobcat]

You're only moving if the if-statement is true so perhaps consider logging what you hit.

[gentle stratus]

it logs null bc the raycast is always false

even when i make the raycast 10x as long it doesnt hit anything

which is weird bc sightradius should set the radius of the sphere it detects the player in

[cosmic dagger]

are you using the correct layer? i'm not sure why you didn't just create a LayerMask variable and select the layers from the inspector . . .

[gentle stratus]

maybe i should try that

if i read correctly the layermask is supposed to have the layers you want to exclude right

[cosmic dagger]

no . . .

use a LayerMask to select which layers a ray should collide with . . .

[gentle stratus]

i might be stupid

ok that is fixed now thanks for the help

[lethal owl]

im learning how to code wtf is wrong with this script

using UnityEngine;
using TMPro;

public class HelloWorld : MonoBehaviour
{
public string firstName;
private TextMeshProUGUI textMeshPro;

void Start()
{
    textMeshPro = GetComponent<TextMeshProUGUI>();
    textMeshPro.text = $"Hello {firstName}!";
}


void Update()
{
    
}

}

NullReferenceException: Object reference not set to an instance of an object
HelloWorld.Start () (at Assets/Scripts/HelloWorld.cs:15)

[rich adder]

Your gameobject doesnt seem to have TextMeshProUGUI on it

just make the field SerializeField and assign it through inspector, much better anyway

[lethal owl]

its on a TextMeshPro object

[rich adder]

screenshot it

[rich adder]

yeah TextMeshPro is not TextMeshProUGUI

[lethal owl]

maybe I should stick to the rectangle screenshotting

[lethal owl]

whats the difference and why did it work

[slender nymph]

TextMeshPro is the world space text object, TextMeshProUGUI is the UI text object, but they both inherit from TMP_Text so just use that as the data type instead

[untold shore]

Hey, currently having a ton of issues with these card resets. Currently, I just want all the previous card objects (the children of hand transform) destroyed, but yet it's doing wacky things like copying them, drawing 4 cards, etc. What can I do to fix this? I've never used an Ienumerator method before, so I'm certain something is wrong with that, but I don't know what it would be. I know this is probably really basic, I apologize, still really new to coding these kind of projects. Thanks.
Code attempting to use:

  public void ResetPlayerHand()
    {
      handManager.cardsInHand.Clear();
      Debug.Log("Cleared cardsInHandPlayer");
      DestroyPlayerHandObjects();
      hand.GetComponent<CardValuesScript>().handValue = 0;
      Debug.Log("Number of children in handtransform before waiting: " + hand.transform.childCount);
      DrawCard(handManager);
      DrawCard(handManager);
    }
  public IEnumerable DestroyPlayerHandObjects()
  {
    for (int i = hand.transform.childCount - 1; i > 0; i--)
      {
        Destroy(hand.transform.GetChild(i).gameObject);
      }
      yield return new WaitForEndOfFrame();
  }

[lethal owl]

so thats why it worked for the tutorial man

but not me he was using a ui object

[cosmic dagger]

it didn't work because they are two different components. You have one component in code and a different component on the GameObject, hence, they do not match . . .

[untold shore]

Alongside:

[cosmic dagger]

wait, you're following a tutorial? i would look at what component they added and how they attempted to access it . . .

[slender nymph]

you aren't starting the coroutine correctly, and not only that but the coroutine will not delay the code in the method it was started from unless that method is also a coroutine that is yielding the start coroutine call

[lethal owl]

https://www.youtube.com/watch?v=lgUIx75fJ_E&list=PLFgjYYTq6xyhtVK6VzLiFe3pmBu-XSNlX

[untold shore]

Coroutine? I apologize, what's that?

[lethal owl]

I can see now they are using a UI component

[lethal owl]

time I think

[slender nymph]

what do you think that second method in the code block you posted is supposed to be?

[rich adder]

no

[lethal owl]

then don't listen to me

[cosmic dagger]

i wouldn't randomly post a response if you're unsure about the correct answer . . .

[cosmic dagger]

you called DestroyPlayerHandObjects in your method. do you know what that method is (a coroutine) and how it's supposed to work?

[untold shore]

To destroy the children of one of the objects, but i have to delay a frame after so the next code can load in without it resulting with the same # of game objects. Sorry, again, very very new to this kind of thing.

[slender nymph]

it's a coroutine

[rich adder]

they're using UI you put a mesh world object, not the same thing

[lethal owl]

I realize that now thanks

[untold shore]

Thank you. Helps a ton

[slender nymph]

also give this a read: https://unity.huh.how/coroutines/waiting

[untold shore]

Y'all are amazing for this stuff! Again, thank you.

[lethal owl]

will I ever need to use const int's in my code?

[cosmic dagger]

that depends on you and what you need in your code . . .

[lethal owl]

im just asking in general

will I ever need to use them for anything useful

[slender nymph]

it still entirely depends on your code and needs. constants are just that, constants. there's nothing else special about them

[cosmic dagger]

they are constant values that cannot be changed. if you ever need that in your code, then yes. it's entirely up to you. we have no way to determine that . . .

[lethal owl]

so if I want to edit my code at all don't add them

[cosmic dagger]

which part about them confuses you?

[slender nymph]

i feel like there might be a huge disconnect between what you understand and what a constant actually is

[lethal owl]

its unchangable code

[slender nymph]

i mean the code itself can be changed, it's a variable that cannot be assigned to at runtime at all

[cosmic dagger]

it's a variable with a set value that cannot be assigned during runtime . . .

[slender nymph]

constants are useful for defining a value you plan to reuse multiple times in the code that should never ever change.

for example, the value of pi is a constant because pi cannot change. it will always be 3.14... so it is something that is typically declared as a constant (and in fact is a constant in both unity's Mathf struct and c#'s System.Math class)

[tough plinth]

Hey guys!
Having troubles with accessing another value from GetComponent:

So I want to get the value from different object, and then assign that value to another variable (or just store it)

But that script changes value from already set one, to 0 for some reason.

Any thoughts?

Full code: https://hastebin.skyra.pw/oqihunofec.pgsql

[keen dew]

If those logs are from the commented out lines, you're logging two different variables

also this scipt does the opposite of getting a value and assigning it to a variable (it assigns a value from this script to the other component)

[tough plinth]

Oh...

Any way of turning that process backwards?

So there is a plane model, which is player, and it has its speed (horizontalInput), and I want propeller to change its rotation speed based on horizontalInput of the player, so in need to get player speed somehow

[keen dew]

The left side of the = is what stores the value and the right side is the value that is stored

[gentle stratus]

getting a weird error here where it both prints out the value of the variable but also throws an error on the same line https://paste.mod.gg/xoanidideyej/0

[keen dew]

so if you want to store a value to currentThrottle then currentThrottle = player.GetComponent....

[tough plinth]

Oh, that's how it works... Let me test it out

[burnt vapor]

What about logging every variable of playerStats.stats[StatNames.Health]?

playerStats and playerStats.stats specifically

[cosmic dagger]

i would check out a beginner C# tutorial first as assigning a variable is one of the first things you learn. it's pretty important . . .

[gentle stratus]

thats a looot of variables but ig i could

[burnt vapor]

Two variables is a lot?

[gentle stratus]

you said every variable

[cosmic dagger]

do you have a duplicate script of PlayerUpdate on a GameObject?

[gentle stratus]

i have like 20 variables in stats

[burnt vapor]

I'm just suggesting you figure out the actual null value here

These two are the first two instances you access

Instead of doing it all at once, start there

[gentle stratus]

that looks like the problem yeah

[burnt vapor]

This is probably the issue

And in that case health is null

Log that too

[cosmic dagger]

yeah, i'd log health and see what value you get . . .

[burnt vapor]

Even better would be to do Debug.Log(health, gameObject); because you can click the log message and get to the gameobject that's at faulth

[tough plinth]

That's what I'm doing now actually, there is a plane course which doesn't require that programming as assigning variables is in a different topic.
I just wanted to do something out of the tutorial course lol

[burnt vapor]

@gentle stratus ☝️

[gentle stratus]

yeah i fixed it thanks

[tough plinth]

Oh.. It was so simple actually.. Thanks for the help guys! @keen dew @cosmic dagger

[keen dew]

You should probably go through a basic C# tutorial at this point

[glossy turtle]

Are there any best tutorials on socket.io

I don't see any best tutorial on internet which explain socket.io for beginners.

[astral falcon]

Define "best". Id say, the most recent ones are the best ones covering latest updates. The rest is the same google as we all use

[deft harness]

GetComponent<Animator>().SetTrigger("GrabLedge"); I'm a pretty advanced Python hobbyist and I'm learning C#. Is this line of code calling a method(SetTrigger) from a Class(GetComponent<Animator>) that hasn't been instantiated? (GetComponent<Animator>()...) Also what is the <Animator> <foo> part exactly?

[burnt vapor]

GetComponent can return null when it's not able to find the component

I assume that's your question?

[languid spire]

no
GetComponent is a method which is being called to retrieve a reference to a Class of Type Animator (hence the <>)
The SetTrigger method is then being called on that class.
Note if the Animator class cannot be found this will thow a null ref exception

[burnt vapor]

<Animator> refers to a generic type. These are used in favour of using the base object type since you are able to use the actual type as a parameter or in this case return type

Before generics you'd have to return an object and pass the type as a Type type parameter, and it was just messy all around because you had to cast it and all that

Maybe look up these keywords because casting and generic types are very useful to know

Also, generic types can have rules to them. If you go to the definition of GetComponent is probably has a rule that the type must refer to a class

[deft harness]

I should of known that I had been cast into generics and type-wrangling lol 🙂

[languid spire]

there is nothing complicated about generics, in fact c# would be a very poor language without them

[rigid tiger]

Generics are pretty weird at first. Imagine something's notation being just T
Yeah.

The T symbol goes against every single standard modern programmers have when it comes to naming conventions

[languid spire]

but it doesn't have to be T, that is just a convention, it can be AbraCadabra if you want

[rigid tiger]

Can you show me that?

[languid spire]

    public class MyClass<Abrabadabra> where Abrabadabra : struct
    {

    }

[rigid tiger]

I will mess around a bit when I get home, I did not know that T was not mandatory

I have never seen anything other than T so far

[runic lance]

you can even have multiple generic parameters and they need to have different names MyClass<Foo, Bar>

[languid spire]

look at Dictionary - T1 and T2

[rigid tiger]

That seems like the natural progression in explanations, I was just about to mention dictionaries. I was googling things and that example came up.

[languid spire]

Had it been me I would have made it Dictionary<KEY, VALUE>

[rigid tiger]

How'd this get past me for so long

Thanks for the information and help guys

[deft harness]

public class Box<T>
{
    private T contents;

    public void Add(T item)
    {
        contents = item;
    }

    public T GetContents()
    {
        return contents;
    }
}

is that a valid generic type?

[languid spire]

yes, perfect

so a declaration could be

Box<int> myBox = new Box<int>()

and contents will be of Type int

[deft harness]

cool

[rigid tiger]

It all comes down to type handling, generics can be dangerous

[languid spire]

dangerous? How? The strict typing of C# will stop that

[deft harness]

I prefer the term type-wrangling. Just as when wrestling a bull, wrestling with types is just as stressful! 🙂

[rigid tiger]

Add in complex polymorphism into generics and it only takes 1 runtime to bring everything down

[languid spire]

do you have any idea how many zero day exploits in C++ are caused because it is not a type safe language?

[rigid tiger]

Javascript, king of unsafe typing :D

[languid spire]

but thats an interpreter not a compiled language

[burnt vapor]

(I wanted to send this message a while ago but I got occupied lol)
So all in all, the following two lines are the same:

var @component = GetComponent<Animator>();
var @component = (Animator)GetComponent(typeof(Animator));

Maybe that makes it more clear

[rigid tiger]

🤔 are there any interpreted languages that are type safe? Now im curious.

[languid spire]

C#

[deft harness]

Oh I love that C# is a type-safe language!

[rigid tiger]

C# is compiled though...
I prefer type safe languages that don't rely on indentation tbh, C# is perfect for me

[burnt vapor]

Don't you mean managed language? I see so many instances of vulnerabilities due to poor memory management and leaks

Shit where unmanaged memory is accessed due to a pointer

[languid spire]

no, source is transformed into IL which is interpreted at runtime

[languid spire]

As well, that is the other drawback of not being type safe

[burnt vapor]

yeah

[languid spire]

this is why I hate when people go UnSafe in C# (yes I am looking at you Unity). It totally fucks up the whole point of the language

[deft harness]

is there any type of repl tool for c#? I know it's compiled but.....

[burnt vapor]

The C# discord has one

[eternal falcon]

Join the C# Discord server, a programming server aimed at coders discussing everything related to C# (CSharp) and .NET. https://discord.com/invite/csharp

[burnt vapor]

They also have a bot spam channel where you can use it freely

Pretty sure the command is !eval

[deft harness]

neat!

[languid spire]

there is this https://dotnet.microsoft.com/en-us/platform/try-dotnet

[deft harness]

actually it wouldn't be too hard to set something like that up that can be used from the terminal....

[runic lance]

there's the csharp command, I think from mono? https://www.mono-project.com/docs/tools+libraries/tools/repl/

I've always used it and never bothered to check where did it came from 😆 on MacOS though, not sure about Windows

[sand moss]

Hi, I am implementing in app purchases. I want to ask if there is a better way to validate receipt without using backend. currently I am validating receipt after the purchase. backend implementation is tricky as the game is small and we are not using any backend for it so no usr login. so I am open to ideas

[rigid tiger]

If you do not use a backend your app will not stand a chance against pirates

[languid spire]

you must use a backend or not do it

[burnt vapor]

Piracy has a lot more to it than just having a backend

Pirated applications are not suddenly safe with a backend
