[slate haven]

are u guys using Untiy 6?

[iron blade]

i am

[slate haven]

How is it?

[iron blade]

really good for 2D, but i dont really understand the 3d

[slate haven]

I am still using 2022.3.11f1

[languid spire]

Unity 6 should only be used by those who really, really know Unity

[slate haven]

Isee, its just beta right now?

[iron blade]

i think preview

[slate haven]

I see

[iron blade]

Ooh i fixed my problem

but now it moves so slow that it just falls

thanks for the help guys

[slate haven]

Decrease the mass

or increase the velocity speed

[iron blade]

oh gosh i made a worm

[slate haven]

ur good

[iron blade]

🤣

[slate haven]

haha

[iron blade]

look ima send u a video

[slate haven]

Alr

[languid spire]

you probably want to freeze the x and z rotation on your rigidbody

[iron blade]

oo yeah that makes sense

[slate haven]

Yes

[iron blade]

thanks

[slate haven]

also do freeze position on Z if you don't wanna make it go in unwanted axis

if its just x movement

[iron blade]

nicee it works now

[iron blade]

nope, im just trying to apply what i learned in 2d to 3d

with the z axis

[slate haven]

What game are you making

[slate haven]

I see

[iron blade]

i dont really know, in 2d i bought a course for unity 6 (platformer) and i was curious about 3d

so maybe a 3d platformer

[slate haven]

Thats nice

Just clear the fundamentals of local space and world space

if your using rigidbodies, thats gonna be really helpful

[iron blade]

How can i make the player no longer move if i stop pressing the key?

[slate haven]

Just add a condition

If (input > 0.1f)
{then move}

else dont

And You have to verify if thats just the input movement or the Physics affecting your object

[languid spire]

set velocity to zero on GetKeyUp

[iron blade]

oh and every project now seems to come with one of those new input systems

by default

[slate haven]

Damn thats great

[iron blade]

i think ill learn that one since its more default now

[slate haven]

Yes, the new input system little hard on the brain but

its worth it

[iron blade]

oh and also

you now have to manually install the Built in render pipeline templates

now the standard is those universal 2d and 3d ones

[slate haven]

urp as well?

[iron blade]

i installed the one on the bottom manually

[slate haven]

Ohh yeah its the same on every unity hub

not just unity 6

[iron blade]

ooh

alr

[slate haven]

I use the universal 3d rn

it has the urp template

[iron blade]

same

[slate haven]

does it happen to you that you understand the whole input system concept, or the movement logic. But when u type the code you just forget that what was it

[charred pilot]

is looking at learning plugin dev got some ideas is it c plus plus and .net

[iron blade]

i forget what it is before i even start typing

before opening unity

[copper python]

It's called being human :P

[iron blade]

before waking up

🤣

[languid spire]

plugin dev for unity can be done with C# and .Net. generally C++ does not use .Net

[charred pilot]

so .net is a good option

[languid spire]

for Unity dev? Of course

[charred pilot]

cool thanks

is the internal editor ok for a start

[languid spire]

you mean the IDE?

[charred pilot]

yeah as a newb

[languid spire]

yes, but when you develop plugins you do so external to Unity

[charred pilot]

ok

[slate haven]

I used
rb.MoveRotation(Quaternion.Euler(25,12,135) in FixedUpdate()

Surprisingly it makes the object fly away. This only happened when I kept the 'Z' Axis value little high. Otherwise this didn't happen in smaller values.

Can anyone explain what's happening??

[languid spire]

Why would it fly away, there is no movement in that code only rotation

[storm pine]

How can I do that a button could only be clicked once?
I have a button that decrease lives and after one click it changes, but if you click two times fast it just decrease 2 lives instead of 1, this is the click listener of the button:

optionButtons[index].onClick.AddListener(() =>
                    {
                        optionButtons[index].interactable = false;      
                        OnOptionSelected(isCorrect);
                        optionButtons[index].interactable = true;
                    });

[slate haven]

Exactly my question. When I put small values it didnt fly

[languid spire]

I suspect you are looking at the wrong thing, this code alone will never cause 'flying away'

[slate haven]

So what would?

[languid spire]

anything which affects velocity

[languid spire]

can you share the complete method !code

RigidBody rb;

Void Start()
{

rb = GetComponent<Rigidbody>();
}

void FixedUpdate()
{
rb.MoveRotation(Quaternion.Euler(25,12,145));

}

}

[languid spire]

your changing of interactable there is complete useless

[storm pine]

It's a long class so I will only be sharing the related methods, is fine?
https://hatebin.com/hbnnwgtqrz
It's for a level that it's like a trivia, so when a option is selected the content of the buttons with the answers and the question changed

[languid spire]

line 14 was what I was looking for, so thars's fine. the usage of interactable still makes no sense

[iron blade]

Yoo @slate haven

[slate haven]

This is the whole code I used

[slate haven]

Yes?

[iron blade]

I implemented the new input system into the movement, now it works great

[storm pine]

Yeah, this was just a way of trying to stop this, just testing. I aslo try with a corroutine to wait

[languid spire]

yes, setting interactable to false and then a cooldown to set it back to true in a coroutine should do the trick

[slate haven]

Thats good bro

Once u get a hang of it, its better than the legacy

[iron blade]

yeah, but i still have some problems with gravity doe

Maybe u know how to fix it?

its at the end

[storm pine]

I tried this way, but still not working, idk what could be wrong or either how to debug this. Maybe because I reference the button using button[index] when maybe index is a different value? I don't know if unity set the listener when is declared or when is executed
https://hatebin.com/wyuwlckeyd

[slate haven]

Did u tick the gravity checkbox in the inspector?

[cinder crag]

you gotta check if the player is onGround , if he is then enable gravity , if he aint then disable gravity

or i think its reverse

[iron blade]

yup

[iron blade]

alright thanks

[languid spire]

that is not how you Start a Coroutine

[slate haven]

I see your player is getting affected by gravity, but its way too slow

[storm pine]

My bad, I'm stupid, long time without using Unity

[iron blade]

ill try what hellio said

[cinder crag]

cant remember on how i did it but i remember something with checking if ur onground

[storm pine]

Is working, thank you so much for your patience

[iron blade]

hm alr

[languid spire]

np. you were damn close, I just gave you a nudge

[slate haven]

Check if any objects in the hierarchy has conflicting rigid bodies with player

[slate haven]

on the child objects of player dont put any rigidbody

always put Rigidbody on parent

maybe try this

[iron blade]

im just gonna continue on my 2d game

[slate haven]

or create a new game Object

[iron blade]

done that already

[slate haven]

and try checking on that

do other gameobjects behave the same way?

to gravity

[iron blade]

nope

[slate haven]

Try creating a new Game Object, put the scipt

script

[iron blade]

i think its cuz of this in the movement

[slate haven]

and Rigidbody to it

[slate haven]

Yeah try that in a new game Object

[iron blade]

cuz the y is always changing to 0f

[slate haven]

and see if its the same

[iron blade]

ima continue on my 2d game

[slate haven]

ohhhhh

[iron blade]

wanna see some of it?

[slate haven]

sure

[iron blade]

working on damaging the player with the spike right now

@slate haven

[hexed terrace]

perhaps make a thread if you want to just talk about your game without help

or DM eachother

[iron blade]

How could I upload stuff to the asset store?

[languid spire]

become an asset store publisher

[hexed terrace]

This is a code channel, ask code related questions. To find out how to become an asset store publisher, I'd suggest googling and read the info Unity provide

[iron blade]

[slate haven]

Thats good

[idle ginkgo]

so how do use the randomValue variable in update

[languid spire]

why do you have randomVal and randomValue ?

[idle ginkgo]

sorry that was so dumb

thanks for helping

[still pond]

ObjectDisposedException: SerializedProperty questions.Array.data[4] has disappeared!
UnityEditor.SerializedProperty.get_propertyPath () (at <fe7039efe678478d9c83e73bc6a6566d>:0)

Does this mean that im trying to acces an object that was deleted?

[slender nymph]

have you written any editor code? because that error is related to editor code

[still pond]

Im at very begging, i dont even know what editor code is. You mean c# scripts?

[slender nymph]

then the answer is likely: "that is an editor error. clear the console and move on"

[still pond]

ok thanks, so nothing to worry about

[eternal needle]

the size of the values mean nothing here, this is just a rotation. The issue is likely in your setup, maybe you have other code affecting this or there are overlapping colliders

also please dont record with your phone, record on your computer. there are many apps to do this, OBS is free and pretty widely used

[slate haven]

Nope, only 1 script, Collider is only on the Plane

Oh yes, I had 2 colliders on the player as well

[eternal needle]

I can see colliders on the object in the video. Try recreating this in a new scene, a basic cube and only attach this script.

[slate haven]

So yeah they interacted with each other

Solved it

[upper tide]

Is it correct to say that the behavior of method hiding is that whe you cast the derived class into the base class, the original base class method is called instead of the "new" keyword defined method;

whereas method overriding will call the derived "override" keyword defined method regardless of what class it's being cast to

[slender nymph]

yes

[upper tide]

Thank you

[slender nymph]

Quick demonstration of that behavior: https://dotnetfiddle.net/fX1Kjo

[upper tide]

Very comprehensive and quick demo

[queen adder]

Question: So I have this Recoil function, it get called once per click, no update

//Unrelated logic removed && names shortened
    public void DoRecoil()
    {
        recoiledRot += new Vector3(x, randY, randZ);
        transform.localRotation = Quaternion.Euler(transform.localRotation.eulerAngles + recoiledRot);
        recoiledRot = Vector3.zero;
    }

This script lerps all the stuff back to its original place

    void Update()
    {
        lerpedRot = Vector3.Lerp(lerpedRot, desiredRot, rotLerpSpeed * Time.fixedDeltaTime);
        transform.localRotation = Quaternion.Euler(lerpedRot);
    }

but it is failing to do that with the rotation, probably because I dont know how to properly lerp rotation, any help?

Im trying out other stuff rn, its the issue with me lerping euler angles directly prob

[slender nymph]

the lerp you've shown appears to have nothing at all to do with the DoRecoil method you've shown as none of the values used in either method are used in the other. Not only that, but you are using fixedDeltaTime in Update for some reason, that is going to make it go faster on higher framerates because fixedDeltaTime does not change as the framerate changes like deltaTime does. also that's a "wrong lerp" and ideally when dealing with rotations you'd use Slerp not Lerp

[mint lodge]

Hey guys

How do I enable Magnet/Snapping tools here?

[slender nymph]

this is a code channel. but if the tools aren't showing up there, then select the 3 dot button in the upper right of the scene view window to open them again

[mint lodge]

I'm sorry, I don't know the right channel

3 dots don't show any snapping options though

[queen adder]

Yeah, well they are related indirectly, the second script is only supposed to lerp the gun back into its position, its easier because I can just add a recoil to the gun, and it will get moved back by the other script, I need it to be like that because of unrelated reasons

Im aware im doing wrong Lerp for now, might not even change it because I dont need it to be accurate

It works as I want it with positions, but I didnt show that in the samples I gave

Give me some time, I messed up big time on the lerp again

[atomic holly]

Hi,
For search a gameObject in a scene with 50 others gameobject in it, is it more optimised to use GameObject.Find() orGameObject.FindWithTag()

[frosty hound]

Well, searching with tags means only searching objects with tags vs every object by its name.

[ivory bobcat]

What exactly are you trying to do?

[atomic holly]

When I switch between my scenes, I want to take 2 gameobjets in the scene to take their transform position

[ivory bobcat]

Hmmm, maybe have a Singleton manager and have the new instances register themselves as references with the manager on Start or something. You would be able to access the two instances directly instead of having to search. For instance, player one and two would just tell the manager which objects in the scene they are and every other object within this scene thereon could access them directly using the manager.

[verbal dome]

Unity keeps an internal list of objects with any tag so FindWithTag would only have to search those

[atomic holly]

Okay I see. So in a script, I put the instance of the 2 gameobjects and take it in the other script by their instance ?

[primal trench]

i think this is where to put this but I'm trying to push my unity project to github
I have git lfs installed and registered to recognize .dylib files
every time i try to push i get this error:

remote: error: See https://gh.io/lfs for more information.
remote: error: File Library/PackageCache/com.unity.burst@1.8.16/.Runtime/libburst-llvm-16.dylib is 124.60 MB; this exceeds GitHub's file size limit of 100.00 MB
remote: error: GH001: Large files detected. You may want to try Git Large File Storage - https://git-lfs.github.com.
To https://github.com/Myusername/myproject
 ! [remote rejected]   master -> master (pre-receive hook declined)```

I've been hitting my head at this for an hour now and idk why it's not working

i also have the gitignore recommended for unity

[ivory bobcat]

private void Start()
{
    PlayerManager.Instance.PlayerOne = this;//Set this object as player one with regards to the manager
}```

[atomic holly]

So don't need to attach a script to the gameobjects right ?

[ivory bobcat]

this exceeds GitHub's file size limit of 100.00 MB

[atomic holly]

Just do a SIngletonManager and take their instance

[primal trench]

yeah
i have git lfs installed

and it has the file recognized

[ivory bobcat]

The script would be on the players in the new scene. They would tell the player manager (a Singleton object - ddol) who they are.

[atomic holly]

Oh okay I see

So I was wrong

And so, PlayerOne is a gameobject stock in the Playermanager script right ?

[ivory bobcat]

It would be an accessible member of an instance of the PlayerManager script - a field or anything (my naming convention implies it's a property).

You can lookup Singleton patterns with Unity on Google - pretty sure vertx has got a generic example somewhere as well. Assuming the Singleton registers itself as the unique instance in Awake and prohibits other managers from existing (as intended with the Singleton pattern), you'd just tell the manager who you are per scene in Start (assuming every scene would attempt to create a manager if one doesn't already exist).

[strong wren]

This isn't really a code question. You shouldn't be pushing these folders. Use a gitignore template for Unity.

[stone saddle]

Could anyone please help with detecting collisions with touch screen actions? Ive been able to get tapping to work but I need to be able to swipe through the object as well. https://pastebin.com/Wj4skwPr

[ivory bobcat]

The Singleton pattern: https://unity.huh.how/references/singletons

[primal trench]

oh alright. sorry. didn't know where to put it really

[rich egret]

hi

All my scripts are not working, what to do?

[wintry quarry]

Follow what it says

First check your console window for any compile errors

[rich egret]

It says "This is not allowed", they worked before

[wintry quarry]

What? Wdym

Show your errors

[rich egret]

And this is not a problem with one script, it is about all scripts

[polar acorn]

What is not allowed

[wintry quarry]

Show your errors

Show the first error.

[polar acorn]

if literally any script has a compile error, then nothing can compile

[wintry quarry]

Once you fix the compile errors it will work

[rich egret]

It just says "This is not allowed" every time I try to open a script

[polar acorn]

Clear the console, show whatever is left, starting at the top

[wintry quarry]

Clear the console and show the first error

[polar acorn]

That is your actual error

[rich egret]

Just one problem with a script I'm programming now

[polar acorn]

You need to fix that before anything can compile

[wintry quarry]

Yep, gotta fix this

[rich egret]

ok its working

@polar acorn @wintry quarry TYSM

[copper matrix]

so i put it at the dge of the map and i still cant put it over the map. I tried it over transform position and Layer Selection but it still doesnt work. the Problem is im working with a duo who designed the Tiles for the map so idk what he did

[idle ginkgo]

my player gets stuck on the edges sometimes

[pliant sleet]

When using Physics.Raycast and you want the distance between the player and the object, what does the "out hit" do in that case ?

[pearl temple]

new to c# and unity.
Are strings compared by reference before being compared by value?
So comparing two strings is actually fast?

[wintry quarry]

It's a RaycastHit struct which contains lots of information about the hit.

https://docs.unity3d.com/ScriptReference/RaycastHit.html

[steep rose]

this

[steep rose]

could you explain furthur?

[wintry quarry]

First by reference:
https://github.com/microsoft/referencesource/blob/51cf7850defa8a17d815b4700b67116e3fa283c2/mscorlib/system/string.cs#L558

[pearl temple]

alright sweet, then they should work fine as dict keys

[wintry quarry]

I mean that doesn't mean it's "fast"

there's no guarantee the two strings are the same instance

unless you're using a const field or something

in which case you might as well just use an enum

it's still likely fast enough, it depends on your use case

[pearl temple]

well I am just porting code now, ported my plugin from unreal to godot, now from godot to unity.
Unreal had FName which are basically hashed so comparing two of them is just comparing an integer.
Godot has StringName which as far as I understand are just immutable string, also compared by ref.

I couldn't find a unity equivalent to either, but I figured if the strings are compared by reference that is close-ish

problem with an enum is that I don't know all possible values at compile time, since users can add more

[wintry quarry]

C# has enums

[pearl temple]

Yes..., I meant that the reason I am not using enums is that I don't know the values beforehand

[wintry quarry]

Just FYI if you're hashing the string that a user inputs, you're still having to iterate over the whole string once to create the hash

I think you're probably prematurely optimizing worrying about this though

[pearl temple]

sure, but that is a one time thing

[wintry quarry]

it's not a one time thing unless you explicitly are saving the hash int somewhere and using that as the dictionary key

[pearl temple]

Ehh, I am hitting a hashmap with hundreds of elements on update for hundreds of objects

[wintry quarry]

have you profiled it

on the target hardware

[pearl temple]

not yet in unity. since I just started porting it

[wintry quarry]

Do it the most straightforward way first, and profile it

if you have a performance issue, then worry about optimizing it

[hollow vortex]

@steep rose for some reason im not allowed to send a pic or sum

maybe bad internet, idk

but I have three parameters, and 6 transitions, 2 between every animation

[steep rose]

what do you mean by "it was not being animated at first (cuz its js some few blinks)"?

[hollow vortex]

im triggering it when the MouseButtonDown, so idk if its related but its not long

making it with no exit time fixed it, but I mean it aint exiting

my code made it not work both ways lol

[steep rose]

you mean the bool is not turning false and stopping the animation?

or the animation stops to quickly

[hollow vortex]

at first or now?

at first it didnt even play I think

[steep rose]

now what does it do

[hollow vortex]

well, the animation just sometimes play

and sometimes not

and it never plays while idle

[steep rose]

yeah im gonna need to see that animator, the code looks fine. its probably something with the animator

[hollow vortex]

its giving me upload fail

oh nvm lemme use a vpn

ight should be sent now

still slow af

[steep rose]

if my memory serves me correct I believe there is a duration float in the parameters on the animations

i would have to check for myself

[hollow vortex]

on the animation or transition?

[steep rose]

check on both

[hollow vortex]

ight the shooting animation

the is shooting boolean is def becoming true

[signal mango]

The Unity equivalent to FName is https://docs.unity3d.com/ScriptReference/PropertyName.html

But it's worth noting you can only turn it back into a string in the editor

[pearl temple]

thank you!

[steep rose]

you may need someone else for this, I was familiar with the animator but i havent used it in a while. From what im seeing it might be something with exit time, im gonna have to reintroduce myself to this to be able to help fully.
I know there are people that can help that have way better knowledge than I do

[signal mango]

Also worth noting that while FName is (iirc?) case-insensitive, PropertyName is case-sensitive

[steep rose]

Im still gonna try to help but it might take me a minute

[hollow vortex]

np ty

[tropic rose]

In my unity project I want my character to turn (rotate) and move towards the closest enemy when the attack button is pressed, but at the moment these movements happen instantly and I have no idea how I can lerp them.
I use the following code:
transform.LookAt(targetLocation);
characterController.Move(targetDirection * speed * Time.deltaTime);
Originally I thought multiplying with Time.deltaTime would do the trick, but it doesn't. Anyone know how to do it properly?

[wintry quarry]

You would interpolate the direction vector/rotation you're looking at

something like:

Vector3 direction = targetLocation - transform.position;
Quaternion targetRotation = Quaternion.LookRotation(direction);
transform.rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);```

[vital vale]

Does someone have an example parallax horizontal scrolling for 2d background

[upper tide]

Is it better to write code with properties instead of fields? Read online that it was better practice because you get proper encapsulation, but I find the unnecessary get/set to be a bit frustrating

[upper tide]

itch.io has a bunch of those free assets

[rich adder]

this isn't really a code question. Also did you look it up.. they have so many guides on this

[wintry quarry]

Best practices are to make all fields private and provide public accessors if and when needed.

[upper tide]

aye aye, so basically to never use public?

[polar acorn]

In general, yes. It makes it really easy to add a listener pattern to send a message whenever the data changes, or to put debug breakpoints on getters/setters to know when something's being modified

[wintry quarry]

never public fields. You can have public properties and methods

[upper tide]

Also was wondering, what exactly is the difference between Delegates and Action? The way you set them up seem identical

[rich adder]

Action is a del

[wintry quarry]

Action is a delegate type

[polar acorn]

Delegates let you specify an entire function signature. Action (and other similar things like Func or Predicate) are specific signatures that you can use

[wintry quarry]

Sort of like how an Apple is a fruit. So you kind of asked "What's the difference between Apples and Fruits?"

[upper tide]

I see

And in this cse delegate is fruit and apple is the type

[wintry quarry]

Apple is Action

Fruit is delegates

[upper tide]

Ah I see, would it be right to say Actions are delegates with void return type

[zenith cypress]

https://github.com/microsoft/referencesource/blob/51cf7850defa8a17d815b4700b67116e3fa283c2/mscorlib/system/action.cs#L12 yep

[quasi veldt]

Alright, math time because I'm messing up worldspace conversion, and I'm not sure where I'm going wrong.

I need to do three things. Listed in order of least likely to have messed up to most.

1: get what the position and rotation of object A would B in A's localspace (which I need for later)
this is done via:

localPosOffset = referenceObject.transform.InverseTransformPoint(this.transform.position); //if we were a child of ReferenceObject, this is what our local position would be.

        Vector3 tempRightForward = this.transform.InverseTransformDirection(referenceObject.transform.forward);
        Vector3 tempRightUp = this.transform.InverseTransformDirection(referenceObject.transform.up);

        localRotOffset= Quaternion.LookRotation(tempRightForward, tempRightUp); //if we were a child object of ReferenceObject, this is what our local rotation would be

From what I can tell, this works perfectly.

I apply it, which also works perfectly, by:

            thing.localPosition = localPosOffset;
            thing.localRotation = thingsparenttransform.localRotation * (localRotOffset);

Where I'm stuck is inverting this w/ the offset I have, so that instead of the values being used to create a child object under the parent, it makes an instance of the parent in the same relative rotation around it (without rotating the object itself), so i can configure it. Works one way atm, but not the other.

my current "stab" at it is dumb, and doesn't properly consider rotation or anything, so I'm kinda fishing here.:

        wouldBeParentObject.transform.position = this.transform.TransformPoint(-localPosOffset); //also dumb.
        
        wouldBeParentObject.transform.rotation = Quaternion.Inverse(localRotOffset); //dumb

basically I get the local offsets of B, which when applied to a child of A result in it being in the same spot as B.

With these same offsets, is it possible to get the inverse, so I can spawn an object & have it be where A would be, if B were the child of A (but it's not, it's just worldspace so I can config an object)

[river quiver]

int randomSoundNum = Mathf.RoundToInt(Random.Range(1.0f, 2.0f));

if (randomSoundNum == 1)
{

}
else
{
    bagietaDyingClip = Resources.Load<AudioClip>("AudioClips/Bagieta-dying-2.mp3");
}

playerAudioSource.clip = bagietaDyingClip;
playerAudioSource.Play();```
why is this not working

i have the bagietaDyingClip variable assigned earlier not in the function itself

[polar acorn]

what isn't working about it

[river quiver]

its not playing, atleast i dont hear it

[wintry quarry]

is the code running? When is it running?

[river quiver]

could it be something in the unitys settings?

its running when the player dies in the gameover function

[wintry quarry]

which runs when?
Also if the player is "dying" are you destroying it?

[polar acorn]

Is the object with the AudioSource on it getting destroyed or deactivated

[wintry quarry]

In which case, are you destroying the audio source?

[river quiver]

no

im not nothing is getting destroyed

it runs when a player collides with a wall or goes out of bounds

[wintry quarry]

well again, you should start with checking if the code actually runs

[wintry quarry]

so OnCollisionEnter or something?

[river quiver]

        {
            endTime = Time.time;
            gameManager.GameOver(startTime, endTime);
        }```
and 

private void OnCollisionEnter2D(Collision2D collision)
{
    endTime = Time.time;
    gameManager.GameOver(startTime, endTime);
}

[wintry quarry]

that top one

is in Update?

[river quiver]

yh

[wintry quarry]

if so it's going to run every frame

and restart the sound every frame

but - again you need to check that your code is actually running

[polar acorn]

Okay, so, in this diagram, A is not a child object of B, but you want it to behave as if it were as B rotates?

[river quiver]

it does cause the menu pops up etc.

[wintry quarry]

ok but which one is running

really you should use Debug.Log to check this

[quasi veldt]

I record the offsets of A to B, so that when applied to a child of A, they match B.

To configure this, I wanna spawn objects in worldspace that'd match up with where A is as B's parent, without moving B basically.

[polar acorn]

Okay, so you want a sort of snapshot of the local transform values of A as if it were a child of B, and then you want to apply those to a different object, after B has moved into a new position?

[quasi veldt]

Yeah, basically. Let's use hands as an example because I'm gonna keep mixing up A/B

Ae, I record the local position of a ball where it'd be in a hand relative to the hand, so I can just move the ball (or Ig attachment point if we're doing hand stuff) to the offset (in local space) to have it match.

to configure the hands, I wanna spawn them in so the offset between them (ae, hand to object) is equal to what I have recorded, but without rotating the base object. So if the hand was configured to be on top of the ball, and I tipped it back 90 degrees or whatever, it'd be on top (but with the same end result if I recorded the offsets again)

[river quiver]

@wintry quarry it was becase i added the format at the end .mp3 lol

[polar acorn]

Okay, so, if you had a ball in the palm of your hand while your hand is held straight out, you'd want to be able to spawn a ball in the palm of your hand while it's upright like a waiter holding a tray. The hand moves and rotates, and you need to keep the relative position.

Just want to make sure we've got the right idea of what the intention is so we don't get too into the weeds of trying to make a specific solution work, in case there's a different way to solve it that might be better

[quasi veldt]

In this case the hand stuff is handled. I can apply the offset to the attachment point on the hand and it'll match up perfectly fine

I'm trying to do the inverse of it. everything would still be the same distance/orientation/etc, but with the ball as the parent instead of the hand. basically applying the offset I recorded (from hand to ideal ball position) backwards, to get where the hand would be if in worldspace the ball was both it's child & in the same position/rotation it currently is

[polar acorn]

Ah, okay, that is a much more complicated problem. What I was reading it as was something actually pretty easy to do with parent constraints but this is a bit more difficult. Gimme a second to think about it

[quasi veldt]

Yeah, no problem. it stumped me too.
Idk if this diagram helps but here;

[polar acorn]

Okay, so, the local position and rotation are basically the difference between the parent and the child, right?
That would mean the hand's transform should be at the ball's world position minus the offset, and the rotation be the world rotation of the ball minus the offset rotation.

I have no idea how to do the quaternion math on that, but let's try it with the position first and see if this idea is sound at least?

wouldBeParentObject.transform.position = transform.position - localPosOffset;

If this puts it where we want the parent object to be, I can figure out the math

[quasi veldt]

wouldn't work. first thing I tried unfortunately, it doesn't account for rotation (ae, if you have the hand pointing @ the bottom left corner of a box, and rotate it 90 degrees, it won't change spot)

...lemmie try etcetc position = this.transform.TransformPoint(-localPosOffset); though. if that works rotation's probably a similar deal

[polar acorn]

Ah, right. Dang

[quasi veldt]

yeah, .TransformPoint also doesn't work, presumably because the offset only works in localposition if the rotation's right. hm

Unfortunately I can't just record the offset both ways, as it's open to direct user (or configurator ig) editing, I've gotta work backwards here.

this double sucks as the unity discussions pages keep giving me 403s (probably because the migration, which I'm sure will go well )

[polar acorn]

Yeah, I'm trying to fiddle with it on my end and am also coming up with bupkis. I'm gonna have to ponder this for a while, this is actually starting to eat into my actual job time. If I come up with something and no one else has come up with anything I'll ping you

[quasi veldt]

Gotcha. I'll ping you if I figure it out lol

[stuck palm]

is there a gizmos.drawcapsule?

[rocky canyon]

https://medium.com/@davidzulic/unity-drawing-custom-debug-shapes-part-9-a4d5283ee6ad

[stuck palm]

appreciate you 😄

[timber tide]

can always just instantiate meshes with wireframe shaders

or transparency

[stuck palm]

i have this really long annoying if statement for different types of collisions. I feel like its really inefficient and was wondering how i could make it better? I have 4 different shapes so i'd have to make 16 versions of this to keep this up 😭

https://gdl.space/epenagewit.cs

[rocky canyon]

re-use an enum and switch statement

[stuck palm]

yeah, i decided to give each class an enum instead of directly checking the class type itself

[stray thorn]

is there sideways movement on a rigidbody? im trying to my character left and right without looking in that direction but i only know Rigidbody.forward()

to move**

[polar acorn]

Well, there's no such thing as Rigidbody.forward()

So if you're looking for something like that for sideways, that also doesn't exist

[stray thorn]

i meant transform.forward

mb

[summer stump]

There is transform.forward
And transform.right

Etc

You can easily look up the docs for the transform component and see it all. That should always be your first stop

[stray thorn]

so can i do transform.right * input.GetrawAxis(Horizontal) and itll work?

[stuck palm]

is directly checking class type expensive in the context of a physics simulation?

[summer stump]

That is not how I would write it, but sure

[stray thorn]

i just summarized

thx

[void raptor]

https://paste.ofcode.org/yYiuUYTrhLKCYVz5gD3FDU i made this simple code that should made the enemy follow me when i am too close but it doesnt work and the enemy stands still even if i am too close

Can someone help me with this bug?

[polar acorn]

Try logging Vector3.Distance(transform.position, player.position) and see what the value is

[void raptor]

lemme try

@polar acorn it gives me the same value when game starts even if i am too close

[polar acorn]

So, the value doesn't change?

[void raptor]

ye

[hollow vortex]

my entry state dissapeard lol

[polar acorn]

And it's always that distance, even when moving the player around?

[hollow vortex]

it also giving me errors with nothing relateed to my code

nvm reset and everythin worked (and gone as well)

[steep rose]

float dist = Vector3.Distance(other.position, transform.position);

[void raptor]

Yes

[steep rose]

dist < 5

thats on the documentation

[void raptor]

ive tried that same problem

[polar acorn]

Then the distance between this object and whatever object you've assigned to player is 12.48762

And that object is not the one that moves around

[steep rose]

other.position first then transform.position

brb

[summer stump]

That shouldn't really make a difference. Since it is just a float telling the distance between two points. Not a vector or anything

[void raptor]

yes

[steep rose]

[summer stump]

Try typing Player into the hierarchy search

[stray thorn]

does anyone know how to check if my character is grounded? is there a isgrounded function in rigidbody?

[summer stump]

I am at work. But I guarantee you it will not change anything
Just think about it for a few seconds and you will see why

[summer stump]

There is not.
Do a raycast (or other spatial query) down to test the ground

[steep rose]

[stray thorn]

alr ty

[void raptor]

it doesnt work

[polar acorn]

It's a displacement, there's no sign on it. It's the same either way

[hollow vortex]

can someone help me fix something in my code

for some reason it's not affecting animtor's variable

it was working a bit ago but I had to reset my animator

[steep rose]

I just posted what it said on the documentation

[hollow vortex]

where?

[steep rose]

not that

[hollow vortex]

oh mb

[eternal needle]

Funny you write this but you clearly didnt try it

[steep rose]

I dont have unity open

[summer stump]

"How far is that rock from me" and "how far am I from that rock" would clearly have the same answer, right?

[void raptor]

is it a navmesh problem? becouse not even chat gpt managed to fix me this bug

[summer stump]

Gpt will likely just make things far worse

You say "not even" as if gpt was capable of fixing it

[polar acorn]

is the same as (a-b).magnitude

Magnitude is an unsigned value. The documentation says it's the same

[eternal needle]

That's irrelevant. I'm just pointing out you really shouldnt just be guessing at issues if you arent confident in what the problem is. Most of us stay out of problems we arent knowledgeable about

[void raptor]

Rip for me

[polar acorn]

I've told you what the problem is. The object you're checking distance to isn't moving

Whatever object player is set to is not the one that's moving around

[summer stump]

Try typing Player into the hierarchy search

#💻┃code-beginner message

[void raptor]

Yeah but the player is moving shouldnt still tell me the distance?

[polar acorn]

Only if that object is the one you dragged in for the player variable

[void raptor]

Yes it is

[summer stump]

Prove it

[summer stump]

Ok, and you did not drag in a prefab?

[polar acorn]

If it were, then the distance would be changing. Since the distance is not changing, the only conclusion is that the object your player variable holds is not moving.

[summer stump]

Drag that in one more time. Just to be sure

[polar acorn]

If you're certain the assignment is correct, then Player does not move.

[void raptor]

Ok

[polar acorn]

Check the inspector for Player as you move around. Does the position change?

[void raptor]

No

[polar acorn]

Then your Player object is not moving

[summer stump]

In ter es ting

What have you been moving then?

[spiral glen]

anyone have any unity functions that may help me create a draggable screen because I can't think of anywhere to start

[void raptor]

I managed to fix it

i forgor that player was an empty object

so i put player body and it works

[summer stump]

Wait. So you are moving the child and not the parent?

Generally you move the parent, and have the model and animations on the child

[summer pilot]

not exactly a direct coding question, this is more vscode related:

does anyone know what extension provides this "tab to complete" option?

[rich adder]

Intellicode

[summer pilot]

thank you 🙏

[rich adder]

also thats Visual Studio not vscode

[summer pilot]

oh, there's a difference???

[rich adder]

yes very much lol

[summer pilot]

i've always called my visual studio vs

LMFAO

WHOOPS

i thought vs was short for visual studio

[polar acorn]

It is

VSCode is not VS

[rich adder]

Visual Studio is a true IDE,
Visual Studio Code is a text editor that can become somewhat of IDE with extensions

[summer pilot]

ahhhhh

[mint lodge]

Hey guys

So I'm trying to create this obstacle (orange rect) that is activated by a Trigger

and moves ping pong between two points

but even though my code works in a similar object that isn't activated by a trigger

it refuses to work for this triggered obstacle

It moves to the first point and pauses

I tried diffferent approaches and it either jitters after reaching the first point or pauses

[rich adder]

thats why the bot has a section marked large code blocks

[mint lodge]

No sorry

[signal mango]

I'm surprised it doesn't suggest GitHub Gist

I guess since you need an account

[rich adder]

why ? thats more work. more friction..

[signal mango]

What do you mean?

putting Logs inside these functions to see what what the current values are vs what you expect, and if they print in the first place

[signal mango]

(I mean https://gist.github.com/ for reference, not a repository)

[rich adder]

we know

like you said you need to be logged in the first place

[mint lodge]

They are printing correctly

and also alternating

[rich adder]

how did you verify

[mint lodge]

    private Vector2 GetCorrectNextPosition()
    {
        nextPointPos = points[pointIndex].transform.position;
        print(nextPointPos);
        print(string.Format("The point index is {0}", pointIndex));
        return nextPointPos;
    }```

Called on Update

The block reaches the first Point and then prints the position of the other point and the correct index

Then the position of the point the block is jittering at and its index

[rich adder]

where is that here, i dont see it

[mint lodge]

old version with same problem

It's only this function called at the start of Update

[mint lodge]

Instead of moving, it keeps jittering

[rich adder]

is the trigger a rigidbody?

[void raptor]

i'll fix that, thanks

[summer pilot]

this is not working for me

[rich adder]

works for me on both, which editor are you using?

[summer pilot]

Visual Studio Code

[mint lodge]

No BoxColl2D

[rich adder]

do you have the Unity plugin and the c# Devkit ?

[summer pilot]

these are ALL of my extensions

[rich adder]

alr maybe a quick vid of whats happening

[stray thorn]

anyone know how i can limit the range to 90, -90?

[mint lodge]

Okay

[rich adder]

clamp

[stray thorn]

wdym?

is there a unity doc on things like this?

[summer stump]

If you google "unity clamp" you will see many examples

[rich adder]

are you moving the whole object with the points?

[summer pilot]

clamp the maximum distance with a max and min value
https://docs.unity3d.com/ScriptReference/Mathf.Clamp.html

[summer stump]

Of course. There are docs on all of it
You have google at your fingertips right now to find it

[mint lodge]

No, the code gets the Child(0) which is the Rhino

but now that you say it, maybe it weirdly changes into the parent object when the Rhino reaches the first point??

I'll try using a SerializeField private var for the Rhino

[rich adder]

where are the Rhino points at

[rich adder]

the hirerchy would nt randomly switch

[mint lodge]

They are empty Game Objects with a transform

not visible in the Scene

[rich adder]

thats why i said put logs in the code and see if the function is still running

[rich adder]

yes im aware

[rich adder]

put Gizmos on them

[mint lodge]

Good idea

and increase render layer order

[stuck palm]

public abstract class FixedCollider : MonoBehaviour
{
    
    public Entity _entity;
    
    public ColliderShape colliderShape;
    
    public Fix64 radius;
    
    public Fix64 height;
    
    public fv2 center;
   
    public fv2 size;

is there a way to hide some of these fields for sub classes that wont use them? like a box or polygon collider wont use radius

[rich adder]

you dont need render order for that

click the Dropdown next to the name and assign an icon u can see in the scene

i usually pick the diamond one

[mint lodge]

You mean this right

It already has the orange one, I thought they don't show up in the Scene

that's why I'm adding sprite with high render order

[rich adder]

they do if gizmos is on

[stray thorn]

its not working but its not showing any error

[rich adder]

sprite renderer has no differences on gizmos, they are completely different

[rich adder]

did you not read the docs?

Clamp is a function that returns a result..

[stray thorn]

there was no example of scenario

[rich adder]

what

[stray thorn]

it just showed a block of code abt animation or smth

[steep rose]

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

bor

[rich adder]

its called an example

[stray thorn]

it didnt match my situation

[rich adder]

do you know how examples work?

you look at them to figure out how its being used..

[steep rose]

am i having a stroke or something 😅

i think so

[rich adder]

this is basic c# reading documentation is essential..

eg what return type the function has etc..

[stray thorn]

i started 4 days ago gng i dont get why ur being harsh

thx tho

[rich adder]

I'm not lol Just saying look at the exmaple , you said it "doesnt fit your usecase "

[mint lodge]

Not reading Documentation is like trying to use a device without reading the instruction manual

[steep rose]

hes not being harsh

[rich adder]

could you show where both points are placed

[mint lodge]

one sec compiling

caught the bug red handed

Thanks for telling me to debug again, I still have to think about how to fix this though lol

So it's not actually changing the Point

[steep rose]

could I see some code?

[mint lodge]

Yes one sec pls

[rich adder]

presumably the index part

but yeah debugging is the best way to find these little things

[mint lodge]

The immortal print statement

[summer pilot]

how do i find my debug log, im logging information to it but it's nowhere to be found

[summer stump]

In the console

Make sure the toggle is not deselected on the top right

And if it is not toggled off, and you do not see the log, then that code is not executing

[summer pilot]

and i find the console where?

[steep rose]

it should be open at the bottom of your screen

[summer pilot]

thats my problem

its not there

[summer stump]

Go into windows at the top, go into panels, and click console

[rich adder]

you can add as many as you want too

[rich adder]

right click the bar where it says Scene

you can probably do Via Add Tab

3 dots button

[summer stump]

@summer pilot Or you can click the blank space at the very bottom (which may or may not have words)

Maybe it is under analysis? Can't remember where exactly in the windows menu. Just look around if you go that route

[summer pilot]

does nothing

[rich adder]

sorry the 3 dots, on the rightside

[mint lodge]

IT'S WORKING

[summer stump]

If you google "unity console" it will of course tell you exactly how to get there

[polar acorn]

Check the other foldouts. Pretty sure console is under "General"

[polar acorn]

But there's not many to look through

[mint lodge]

Thank you @rich adder

[rich adder]

aw fawkkk

thats the ONE they dont have wtf lol

[summer stump]

Stop sending pictures. Just look through all the windows menus

[summer pilot]

it was there, than k you

UX failure

[summer pilot]

i was already in this chat where people were willing to help me, why are you being so adamant about being a dick to me

[summer stump]

Wow, rude. I was not. I pointed you where to go. Please do not call people names

Sending all the pictures floods the chat and makes it hard for others to get help

See #854851968446365696 and #📖┃code-of-conduct
Especially the part about trying to find the info yourself before asking here. It is a quick google

[summer pilot]

when there are others who are walking me through where to look, i don't need you sitting there telling me to stop what im doing and making me feel like im doing something wrong. 2 people were telling me exactly where to look as I am still new to unity in general, let alone their super confusing window UI

[steep rose]

woah now, lets cool it

[summer pilot]

i was also already in this chat asking this question when people were telling me to access the console

[summer stump]

Sending pictures over and over IS doing something wrong.
And I told you exactly where to look

I was the one who told you it was in the console, and to look in the windows menus.
But whatever, if you wanna be rude, just gonna block you.

Best of luck with everything. Please be nicer to others and grow up in the future, because this is not it

You are welcome for being the first person to help you and tell you everything you need.

[summer pilot]

whatever man

[mint lodge]

Stop fighting

It's called Unity

[steep rose]

now that is true

[stone saddle]

is anyone able to tell me if this is correct? no debug messages are being printed when the objects interact and i dont see any issues with tags or colliders.

[polar acorn]

Put a log outside the if and log the tag of other

See if that prints

[stone saddle]

nope, still nothing

i cant find the issue

The Three Commandments of OnTriggerEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt tick isTrigger on at least one of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

[half egret]

The 3rd commandment is one I always forget

[stone saddle]

would the game being 2d perchance make a difference

did i forget a 2d somewhere

[polar acorn]

Yes

Because this is the 3D OnTriggerEnter function

[stone saddle]

ahh

[polar acorn]

You should probably be using OnTriggerEnter2D

[mint lodge]

How did IntelliSense not correct you

[polar acorn]

Because OnTriggerEnter is a perfectly cromulent function

It just isn't called by a 2D Rigidbody

[mint lodge]

Mine turns to 2D automatically

I'm working in a 2D project

[stone saddle]

works fine now, stupid mistake, thanks

Thou is right, I forgot to check isTrigger

[summer stump]

Keep in mind, this has no validation and will destroy themselves when hitting ANYTHING.
Figure it's a test, but just worth mentioning

[mint lodge]

I have a question

[steep rose]

shoot

[mint lodge]

I want to create an Obstacle that moves this way

[polar acorn]

Sine

Well, specifically, absolute value of sine

[mint lodge]

on Y axis I presume?

[half egret]

DOTWeen has the jump ease

[mint lodge]

no, X

[polar acorn]

If that's the axis you want it to move on

[half egret]

That sees this exactly

[mint lodge]

Thank you, I'll check out both ways

[quasi veldt]

I took the coward's way out. a false victory. a weakling's approach

but it works lol, just juggled parents & used the offset the same way I normally do, then put the object as a parent of what used to be it's child & restore it's old worldposition

[polar acorn]

I was so deep in the weeds trying to figure out the math I legitimately did not consider that as an option

[quasi veldt]

it's a shitty option but it's better than it not working. Ideally I'd understand the math but ig my brain isn't big enough for that yet

[ashen trail]

How can I make a bullet shoot from a players position but not destroy the player? Is the solution to spawn the bullet just a bit in front of the player or is there another way?

[summer stump]

I just mentioned that above
#💻┃code-beginner message

Validate the collision

[polar acorn]

Instead of just destroying literally everything it touches, maybe check to see what object you hit first

[summer stump]

if (thing I want to destroy)

[ashen trail]

Thank you I saw your comment earlier but I just wasn't sure how to validate the collision

[eternal needle]

I also really wouldnt have objects just destroying other objects like this

[ashen trail]

Do I hake different bullet prefabs for the enemy because if I tell the bullet to not destroy the player than the people firing at the player can't do anything.

[ashen trail]

This is the only way I know how to as of right now but I'm working on getting better with the code.

[summer stump]

Call TryGetComponent in OnTriggerEnter on a damageable script and say bullet hit, pass it some value, and that script will decide whether or not to destroy itself

Or have a bool on your script that tells it whether it is the player or not.

If not, damage player
If it is, don't

There are many ways to do it

[ashen trail]

Okay, the bool makes sense to me, I will try coding that and see how it goes.

[eternal needle]

Depending on the use case you could keep it as is, but it's usually better if you call a function on the object the bullet is hitting. Then the object can destroy itself if it's dead and also choose to play animations/sounds before being destroyed

[stray thorn]

i have a capsule as my player and it keeps tipping over since i have a rigidbody, how do i freeze the y and z coordinates of the rotation and keep the x availible

[mint remnant]

there's constraints on the rigifbody for rotation and position you can toggle

[steep rose]

make sure you are not in debug mode, ive made that mistake 1 to many times 😅

[stray thorn]

i already have those on and it still tips over

[half egret]

Show your constraints

[eternal needle]

You probably want to freeze x and z

[stone saddle]

I researched the issue and it said this could be code related? Not sure what it means by type mismatch.

what type does it want its just an object with a script

[stray thorn]

ohh yeah i confused x with y

tysm

[polar acorn]

What type is the Money Manager variable

[stone saddle]

im trying to reference another script named money manager

[rocky canyon]

type mismatch.. for example.. you reference a Coin.cs but instead u try to drag in a SodaPop.cs

[polar acorn]

Okay, and what object did you try to drag in? Show the inspector of it

[polar acorn]

Okay, and are either of the objects involved in this prefabs?

[stone saddle]

ah yeah

the one with ball controller is a prefab

a ball

[polar acorn]

Prefabs cannot reference objects in the scene

[rocky canyon]

so, unless ur MoneyManager is inside that prefab u can't drag a reference in like that

[polar acorn]

you need to set the reference on the instance in the scene after creating it

[rocky canyon]

you need to assign it during runtime via some assignment in Awake() or Start()

[stone saddle]

ohhh

thank you

[rocky canyon]

or some other type of interaction between the 2

[stone saddle]

Its hard to remember all of these seemingly small things

[rocky canyon]

mmhmm, it becomes muscle-memory-esque

the longer u do it

[devout flower]

Is Task.Delay the only thing for tasks that doesn’t work in webGl

[ashen trail]

Am I calling for the player position wrong?

[frosty hound]

No, that is how you get the position of an object.

But you're assigning the position to a Transform type, they're not the same.

Hello everybody, i have one question: Why I can`t see objects that are floating in Play Mode? I have position.z -10 and order in layers 1.

https://github.com/SpawnCampGames/Resources/blob/main/101/WebGL.md just a list i was putting together of WebGL limitations and whatnot..

i dont build in webGL very often.. but its something i been meaning to educate myself about

[ashen trail]

How do I fix it?

[polar acorn]

@topaz niche Go into 3D mode, show where the objects are in relation to the camera frustum

[rocky canyon]

Transform and transform are different things

[loud mango]

why does rb2d.AddForce not work on android build? It works in the editor

[jaunty wedge]

make it Vector3 instead of Transform I suppose

[polar acorn]

Don't try to store a square peg in a round hole

[rocky canyon]

Transform is the <Type>
transform is the specific Transform the script is attached to

[polar acorn]

your FirePoint variable is a Transform. Player.transform.position is a Vector3. These are different types

[rocky canyon]

transform.position <-- "this transforms position"

[loud mango]

i am trying to make a jetpack kind of thing, it tried it with transform.position += ( code )

[polar acorn]

What is .Transform?

[topaz niche]

Thank you very much)

[loud mango]

help me with this please 🙏

[rocky canyon]

Firepoint = Player.transform ❔ ❓

[loud mango]

why does rb2d.AddForce not work on android build? It works in the editor
i am trying to make a jetpack kind of thing, it tried it with transform.position += ( code )
HELP PLEASE 🙏

[steep rose]

dude

[ashen trail]

omg that worked, sorry I couldn't understand a lot of stuff you guys were saying I'm not too good at coding.

[steep rose]

i was just getting to you, chill

[rocky canyon]

Firepoint is a Transform...
Player.transform.position is a Vector3..
Player.transform is a Transform..

[polar acorn]

You're going to need to explain what "not work" means

[loud mango]

it just doesnt jump or fly

[polar acorn]

And what you're actually doing with it

[steep rose]

show us code

[languid spire]

have you tried to debug your build using LogCat

[loud mango]

it clicks the button but it just doesnt fly

https://gdl.space/xejevaheso.cpp main movement

https://gdl.space/osalohatin.cpp detect button

[rocky canyon]

so you've debugged the method and confirmed that the code is indeed running

[loud mango]

the code is correct

cuz i tried flying with a different method, it works

just the AddForce doesnt work

[polar acorn]

You shouldn't mix force-based and teleportation-based movement

They'll fight with each other. You should use entirely teleportation or entirely physics

[loud mango]

using force based in left/right isnt what i want

but using teleportation based on jumping is fighting with the gravity

[languid spire]

#🏃┃animation would be a good choice, not a code question

[grand cosmos]

alright thanks

[jaunty wedge]

Hey, I'm making a rhythm 2d game and I want to add telegraphs to the attacks, but the issue I've ran into is that I need to spawn the attacks on beat, rather than the telegraphs. Does anybody know whether async is better than using coroutines?

I've done it so that the telegraph spawns exactly 1 beat before the following attack does, and it fades in and out before being destroyed. The attack should spawn right when the telegraph is completely visible, and the only way I could figure out was using async or coroutines, but I'm not sure if that's the best solution

[thorny basalt]

Personally, I would implement a data structure that holds information about when the note plays in the song, and using multithreading.

[jaunty wedge]

oh well I'm using Unity Events with double floats (x & y) to call the needed spawning functions, and I call the events when the note I need hits

[crystal chasm]

What's the issue?

[jaunty wedge]

I'm not sure if using async is optimized well enough, and I'm also getting a bunch of errors when I stop the game before an attack is spawned

the errors itself don't really do much as when they appear the game is already ended but they still are a sign that I might be doing something wrong

Your script should either check if it is null or you should not destroy the object.```

[crystal chasm]

Why are you using an int for the timer?

[jaunty wedge]

because that's what the Task.Delay() function takes in

[crystal chasm]

Oh. Lol

[jaunty wedge]

that's actually the reason why I started doubting using async, as the resulted time in milliseconds comes out to be not as precise

for example: with a bpm of 128 each beat takes 0,46875 seconds to play, but the same value in milliseconds can only be represented as 468/469.

[crystal chasm]

Yeah. That doesn't sound very precise

[jaunty wedge]

I'm just curious whether using coroutines would be a better solution to this

or if there's any other viable solution

[crystal chasm]

Coroutines you can at least use a float

[jaunty wedge]

true

but then I need to start the coroutine in a separated function

and use that one instead

so it is quite odd to use as well

there's actually a bunch more issues I've had with the way I implemented telegraphs, but it would be too complicated to put in a single message or a screenshot

so I'm just searching for solutions from the rock bottom lol

[crystal chasm]

That's all you can do sometimes.

[frank zodiac]

not really a coding concept but i just want to ask; what is multithreading and why do we use it

[rich adder]

to run multiple threads /s

[polar acorn]

CPU cores can only do one thing at a time, ever. Your computer seems like it is doing a bunch at once but it's actually just changing between them very fast.

Modern CPUs actually have more than one core, so each core can do a different thing. Multithreading is writing code that can run on multiple cores at once, letting you actually do more than one thing at once. This is generally not actually used in Unity, because UnityEngine functions only work on the main thread.

[frank zodiac]

how do i use this or enable this?

outside of unity

i mean anywhere whatever game engine

[polar acorn]

Depends on the language

[frank zodiac]

what about c++

[rich adder]

https://learn.microsoft.com/en-us/dotnet/standard/threading/using-threads-and-threading

[frank zodiac]

thanks

[rich adder]

btw Unity works with c# not c++

[frank zodiac]

im aware, i dont use unity that often and im transitioning to c++ for gamedev so thats why i was asking

about things other than unity

the only reason i asked in this server was because quite frankly all the other servers are dead

[stuck palm]

why do some of the scripts not have an option to be disabled?

[polar acorn]

If the script has nothing that would be affected by being disabled, it doesn't have a checkbox

[rocky canyon]

no code is dependent on it

[polar acorn]

So, if there's no Start or Update or anything, it doesn't give you a checkmark

[stuck palm]

right

[spiral glen]

is it possible to fill an entire array (hypothetically of a size of 3 values) without doing:

array[0] = blah
array[1] = blah2
array[2] = blah3

[rich adder]

use a loop

[spiral glen]

the values of blah are gonna be different, that'll only help with the placement part of it

[rich adder]

what are you trying to do exactly

[spiral glen]

I have 3 arrays that'll be chosen if an int is equal to a certain value (e.g. 1, 2 or 3)

I don't know if I can instantiate an array with built in values

[slender nymph]

use collection initializer syntax

[spiral glen]

what is that?

[slender nymph]

google it

[spiral glen]

that might work

[spiral glen]

arrayPlacement(1,2,1,comboChoice[]);
if I make a function that requires the input of an array would I implement it like this?

(comboChoice[]) being the array

[polar acorn]

I have no idea what this is asking

[raw token]

Coroutine iteration will be the same as your framerate, so it may be better or worse than Task.Delay() depending on the platform and framerate...

But since you can't really change your visuals faster than the framerate anyway, I would think to decouple the telegraph and the attack, and spawn each as close to their respective beats as possible. If you modify them such that you can set their states to specific times, you could immediately update each right after they're spawned in order to compensate for the delay between the frame and the beat - this way the animations and such should still be dead-on with the beat, and in the very worst case the player will miss out on one frame's worth of animation/effects

[verbal dome]

What are 1, 2, 1 here?

[spiral glen]

        ar[0] = a;
        ar[1] = aa;
        ar[2] = aaa;
    }```

mb should of included this

I'm having an error when inserting the array into the function

where it says I need to add a ;

[verbal dome]

You dont add [] when calling the function

[polar acorn]

Okay, so pass it three ints and an array of int

[spiral glen]

oh ok

thanks

[jaunty wedge]

Thankssss

I'll try that

[wanton kraken]

hey fellas. i've recently added some code to my game that runs upon firing a bullet. it's meant to pull the correct variable from the bullet prefab, and then add that force as relative force on the player. everything is set correctly in the inspector, debugging shows me that it's pulling the correct variable from the bullet, the code is definitley running, and no matter what number i use, no force is being placed onto the player. any ideas?

        if (hit.collider == null)
        {
            Vector3 spawnPosition = transform.position + transform.up * 0.5f;
            GameObject bullet = Instantiate(CurrentBullet, spawnPosition, transform.rotation);
            Vector3 knockbackDirection = -transform.forward;
            PlayerRB.AddRelativeForce(knockbackDirection * CurrentBullet.GetComponent<Bullet>().BulletKnockback, ForceMode2D.Impulse);
        } else {
            deny.Play();
        }

[verbal dome]

Are you overwriting the player rigidbody's velocity in a movement script or something like that?

[wanton kraken]

nope, player movement works by adding relative force as well

that was my first thought lol

damn. got no idea!

[raw token]

What object is this script on, out of curiosity?

[wanton kraken]

it's on the BulletSpawn object, a child of Player which acts as an invisible point to fire bullets from

everything works fine, and i can't see why the knockback portion isn't working. quite odd

anyone have an idea?

[stuck palm]

how can i make my own version of ontriggerenter and oncollisionenter that would work the same way? like i just put it on anything with my own custom collider and it will send the message accordingly?

public void FixedTriggerEnter(FixedCollider other)
    {
        
    }
    
    public void FixedCollisionEnter(FixedCollider other)
    {
        
    }

[polar acorn]

When do you want it to be called?

[raw token]

It looks like you're working in 2D... is transform.forward the correct direction? Wouldn't that move them on the Z axis?

[stuck palm]

When a collision / trigger is detected in my custom simulation manager.

can i send out a message or something?

[polar acorn]

Yes, actually.
https://docs.unity3d.com/ScriptReference/GameObject.SendMessage.html

[wanton kraken]

oh shit, maybe it should be transform.up. ill try that.

[polar acorn]

But it's fairly slow, since it attempts to call that function on every behaviour on the object

[wanton kraken]

you're the best dude, that was it. i really had no clue, thanks a bunch

[polar acorn]

If you could do a TryGetComponent and call it directly it'd be better

[stuck palm]

will do this. thanks!

[slender nymph]

use an interface rather than a specific component and you'll be able to implement it on any component

[stuck palm]

what so like ICollisionReciever or something

[slender nymph]

yep

[stuck palm]

okay, will try this

so like

TryGetComponent Icollisionreciever . OnTrigger

[stuck palm]

within my simulation manager?

[rocky canyon]

not sure exactly how to do it w/ triggers i use a raycast but thats the TryGet w/ an interface

[stuck palm]

okay

thank you!

[slender nymph]

just note that unlike using SendMessage which attempts to call the method on every monobehaviour on the object, TryGetComponent will only get the first component with that interface that it finds

[stuck palm]

ah that could be a problem

cus some things would have multiple colliders

[polar acorn]

This might be the one use case where SendMessage is actually preferred over manually getting the component

[stuck palm]

probs

i'll do that then

how does it work for ontrigger again?

only one has to be a trigger for it to be a trigger collision

[polar acorn]

You'd just call SendMessage on an object and it'll call the function with that name on every behaviour on the object

[ivory bobcat]

https://docs.unity3d.com/ScriptReference/GameObject.SendMessage.html

[slender nymph]

i'm curious what the purpose of all of this is. if you're just replicating how unity's physics already works, why not just use that? 🤔

[stuck palm]

because i need to do it with a fixed point number system to ensure determinism for my game

[wanton kraken]

my code for knockback should be applying force correctly. it's -transform.up, so it should be in the direction opposite to what the player is facing, instead, when the player is facing downwards, this pushes the player downwards as well. any ideas?

[raw token]

I was kind of wondering about applying a relative force relatively... but I didn't quite think through it all. You might try swapping to AddForce though

[wanton kraken]

you've done it yet again, dapper racoon. you are truly a light in the deep darkness of C#

thanks a bunch 🙏

[ember tangle]

are there any negative consequence from making a vector 3 nullable? Vector3? foo

[polar acorn]

Other than all of the annoyances that come from dealing with nullable types in general, probably not

[summer stump]

Try using a Vector3? somewhere expecting a Vector3 and let us know if that is a negative consequence

[ember tangle]

I cant use Vector3.zero and the easiest solution I can think of uses a null value

[ember tangle]

can you give some examples of why it would be annoying?

[slender nymph]

can you describe your actual usecase

[stuck palm]

if i make something readonly how am i ever meant to set the value?

[eternal needle]

In the ctor

[slender nymph]

you would create a parameterized constructor to assign the values

[stuck palm]

right, thanks

[polar acorn]

When passing it to a function that expects a Vector3

and you need to check and unpack the value

[ember tangle]

a Vector3? click is assigned hit.point from ray cast against a terrain so long as the player clicks within the 'map bounds.' If the player clicks the terrain outside of the map bounds, a null value is set and a null check stops the command from being issued. Its the only Vector3 that needs to be nullable.

[steep rose]

also bawsi im sorry if i was being a dingus earlier

[eternal needle]

Raycast returns a bool if it hit or not. You dont need to null check something here. Nullable is totally something you can do, but im not a fan. It's something you need to design around using

[eternal needle]

Honestly I dont even remember what happened, if anything happened.

[slender nymph]

i don't understand the need for that to be nullable. if you're going to be checking whether the hit point is valid or not, just don't issue the command if it isn't a valid point? why do you need a nullable Vector3 to not issue the command?

[steep rose]

i was being a dingus,

[rich adder]

yea nullable overkill here

[eternal needle]

I could see it being useful if you're making some public vector3 and someone else was using this code. But in my own code I've never felt like I needed or wanted nullable

[ember tangle]

the terrain is much larger than the 'play area.' I'm checking the hit.point with bounds.Contains(hit.point) You guys would just recommend using bool isValidClick or something?

{
    click = hit.point;
    Debug.Log($"click = {click}");
}
else
{
    click = null;
    Debug.Log($"click = {click}");
}```

[slender nymph]

you're not really providing enough information about why that bool or the nullable Vector3 are even necessary

[slender nymph]

why are you not just doing whatever checks and stuff you need inside the if statement here?

what is the point of assigning a variable and doing the checks elsewhere?

[ember tangle]

hmm... when you put it that way

[slender nymph]

remember the KISS principle. don't overcomplicate things

[ember tangle]

yeah lol why would I ever not just check BattleMapManager.Instance.battleBounds.GetComponent<BoxCollider>().bounds.Contains(hit.point) instead of changing all these classes to accomodate a nullable Vector3. Damn.

[slender nymph]

or if the point is for other objects to be notified when a valid click happens, just invoke an event in that if statement intead of polling the check variable

[summer stump]

accommodate a nullable

That right there was my biggest annoyance when trying them. It is essentially a completely different type. You start down the road of changing all your internal api, then hit the unity api which you can't change and need to make workarounds or conversions and it is just... so much more work than most other methods

[primal trench]

how do i make an array?

a variable which is an array

[teal viper]

This kind of things you learn by going over C# basics.

[teal viper]

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

[mint remnant]

int[] a;

[primal trench]

ik i already know other programming languages and didn't realize it was different in c#

[teal viper]

Well, that doesn't change the fact that you don't know C#. If you know other languages, learning C# basics would be a breeze. Do it now before it's too late.

[primal trench]

ik i learned a lot of it just skipped over arrays because i assumed they where the same

also my problme is i have an array
Perk[] PerkArray = {};
but i cant refrence "PerkArray" later on in the script

[primal trench]

Yeah ik i was dumb T-T

i was getting impatient and bored

[teal viper]

This is also probably due to missing the C# basics

[mint remnant]

try a List instead, probably simpler to understand

[teal viper]

You'll need to share more of the code

[primal trench]

just looked at that, that's closer to what im looking for

[mint remnant]

but don't forego what dilch said, learn the basics primarily

[vapid yew]

My character controller is Jesus. It defies the laws of Move() and gravity despite being !isGrounded.

Annoying problems:

• The radius is set perfectly for my game world. Can not make smaller.
• I can not change the skin width otherwise the controller susceptible to friction slow falling when hugging a wall.
• I do not want the player to be able to traverse > 60 deg angled slopes.

[teal viper]

You'll need to share some code as well

[primal trench]

i checked microsofts documentation and in theory i should be able to do

PerkArray.Add(Whatever);

but if i try and do that it shows Perk array being non-existent
this is within a public class serializable class, which is in a public static class
I can show full script if needed
i checked the docs and that should work

[vapid yew]

You can see in the camera mini-view the player is visually well overextended.
I believe the Capsule collider is getting stuck on the curved edge as seen in the wireframe view.

@teal viper What part?

[teal viper]

An array doesn't have an Add method and can't be resized.

[primal trench]

this is a list

not an array

woops

the first peice of code is

List<Perk> PerkList = new List<Perk>();

this is the same as shown on microsoft's docs except instead of string im using my class, Perk

[teal viper]

Share the exact error and the whole !code

}

there's also some other errors but they are related to perklist not existing

[teal viper]

That's another part of missing the C# basics. You can't call methods in the global scope.

And you can't add types to a list

[primal trench]

ohhhhh

[teal viper]

Unless it's a list of types.

[primal trench]

yeah

I'm coming from godot so I'm used to you being able to make that kinda thing

[vapid yew]

void Update() {

    // Check if player is grounded
    groundCollisions = Physics.OverlapSphere(groundCheck.position, .4f, groundMasks);
    if (groundCollisions.Length > 0 && velocity.y < 0) velocity.y = -2;
    
    // Movement controls
    Vector2 movement = playerInput.Movement.Movement.ReadValue<Vector2>();

    Vector3 move = transform.right * movement.x + transform.forward * movement.y;
    controller.Move(move * movementSpeed * Time.deltaTime);

    // Landing
    if (!isGrounded && !isPlayingSFX && Physics.CheckSphere(groundCheck.position, .4f, groundMasks)) {
        // Land shit
    }
    
    if (groundCollisions.Length > 0) {
            isGrounded = true;

            // Dynamic movement speed
            movementSpeed =  isCrouching ? 2.5f : isSphereGrounded ? 5 : 6;

            // Jump
            if (playerInput.Movement.Jump.IsPressed() && !isJumping) {
                isJumping = true;

                velocity.y = Mathf.Sqrt(jumpHeight * -2 * -19.62f);
            }
        }

    // Apply gravity and move player with bridge 
    velocity.y += -19.62f * Time.deltaTime;
    controller.Move((velocity + externalVelocity) * Time.deltaTime);
    externalVelocity = Vector3.zero;
}

@teal viper Here's the abridged version

[teal viper]

In C#? I don't think so.

[primal trench]

nooo
godot uses gdscript

and in gdscript u can make a list equivelant

and im used to u being able to add methods (or functions) to them

[teal viper]

Ok, well I said multiple times, but C# is a different language. Go learn the C# basics.

[primal trench]

ok ill read through some of that

[teal viper]

On the first glance there doesn't seem to be a problem, so you'd need to debug it. Place logs or use visual debugging to see where and how much movement is applied to the character and where it comes from.

[vapid yew]

I'm telling you it is the character controller capsule collider itself getting stuck on the ground whenever the collider begins to curve.

If I disable my PlayerControls class the fucking wise guy just hovers there

[slender nymph]

well yeah, the CharacterController does not have built in gravity

[long vortex]

sup

[vapid yew]

@slender nymph Wait a second you're right

[slender nymph]

i usually am

[zenith cypress]

You only get gravity with a CC by default if you use .SimpleMove(speed)

[vapid yew]

Well hang on then

[mint remnant]

@primal trench also think about what you're attempting to do there, a container of Perks inside hte Perk class, you add a perk and it too has a container of PErks too now. Typically a container goes outside of the class that it wants to contain

[long vortex]

`void Update()
{
touchin = Cd.touchin;
if (touchin == true)
{
questbeing.SetActive(false);
fatbeing.SetActive(true);
fatsurround.SetActive(true);
fattext.text = "isudfhisuf";

    }
    if (Input.GetKeyDown("q"))
    {
        Debug.Log("q was pressed");
    }
    
}`

[slender nymph]

three back ticks, not just one

[vapid yew]

Regardless of your point @slender nymph The guy's still hovering.

The PlayerControls and gravity are enabled

Yet that small enough lip is enough to carry his entire weight

[devout flower]

is there a way to reset gizmo settings?
i'm drawing a sphere but it's turning out as an oval

[slender nymph]

let me guess, it's hovering about the CC.skinWidth above the ground?

[long vortex]

so basically my problem is when the first if statement is done even once, the second just doesnt work almost like its stuck in the first if statement, even if its condition isnt met anymore

[vapid yew]

He's not hovering "above" he's hovering over the edge. He should be falling.

Yet that tiny contact point on the edge of the capsule collider is enough to hold the entire player up

[slender nymph]

the CC's capsule collider has absolutely nothing at all to do with your ground check since you do that manually with the OverlapSphere

use the physics debugger to visualize your overlap sphere so you can see how large it actually is

[vapid yew]

The player is NOT grounded when this issue occurs

If I position the player any further over the edge the built up velocity from "free-falling" shoots me down

[slender nymph]

then your capsule is too wide or your ground check sphere is too small. they should have the same radius considering the CC's collider coming into contact with any object during its downward motion will stop that motion. just like any collider that is large enough (in any way) to be in front of it at all when you move forward would stop it

and of course you have to consider the skin width of the CC for collisions

[vapid yew]

I can not change the skin width or the player radius for the reasons outlined in this post.

[slender nymph]

the only reason you gave for the skin width was related to how you do your ground check and apply gravity

[vapid yew]

Changing the skin width does not effect the results of the issue. I have tested with above, below and equal to 10% of the radius.

[slender nymph]

okay well at this point i've explained why your issue happens. so you can either correct it or not 🤷‍♂️

[vapid yew]

My capsule and ground check radius are not incorrect. I have tested this.

And yes I consider skin width in the positioning of the ground check

[slender nymph]

well then i'm happy to hear you don't have an issue

[primal trench]

ok after reading and watching some videos i think i understand better now
thx for the advice!

[teal viper]

Maybe a bit too fast to get ahold of the basics, but glad you got it.

[primal trench]

i already knew some of the basics, just never got to arrays because i got bored and overconfident

sorry for being stupid to u :p

[slender nymph]

sure, but again if there is any collider that the CC can collide with below the CC when it moves downward and its collider would collide with that (taking into account its skin width as well, meaning your CC is effectively 0.58 units wide, not 0.5) that will stop it from moving downward

i genuinely do not know how i can be more clear about that, colliders in its way stop the CC from moving because that is what the CC is meant for

[round plover]

having trouble dragging my text script into my score text so it would show me the position of my cube the further it goes but it wont let me drag it and put it in there

[rich adder]

what type is the field. I cant see shit from these cropped photos..

[round plover]

what do you mean

yeah server wouldnt allow me to send bigger photos

[rich adder]

if you are gonna crop at least make it make some sense.

[upper tide]

If Action is the void return type of delegate, do event delegates exist since event actions exist?

[round plover]

yess
