#

I'm not going to prescribe this for you. Put it on a script somewhere that makes sense

#

I assume since you are making a networked multiplayer game, you must have some basic programming sense.

#

if not, you are in way over your head

main coral
#

Multiplayer not

#

I never heard about !IsMine

leaden ice
#

you just said here you're making a multiplayer game

main coral
#

Yes

#

I rebuilding my game

#

as muiltiplayer

leaden ice
#

networked multiplayer, or local multiplayer?

spring creek
main coral
#

First local

#

And then trying for networked

#

But I start with Local

past wasp
#

I always had one question to netcode, the peer to peer has cost ?

leaden ice
main coral
#

Whats easier ?

leaden ice
#

in local multiplayer you need to have multiple actual unity cameras

#

a FreeLook is NOT a Unity camera

#

it's a thing that controls a unity camera

main coral
#

Can I show u my screen one time ?

leaden ice
#

you can freely post screenshots and videos here to explain your problem

#

or in a thread

main coral
#

Ok

#

What GUIStyle is GUI.Button() using by default?

#

Hello everybody, i don't know if it's right channel but: on runtime some objects are creating on the screen. I do not have a code to create them, could they be some kind of warning for something?

image.png
leaden ice
#

presumably on a script in the scene somewhere

toxic lodge
leaden ice
#

so I assume something in your game has changed

#

or you didn't notice them there yesterday

#

things can also change that are not code

simple egret
#

Do a solution-wide search for "floating text", that name seems like something a human would write

toxic lodge
#

Unity crashed like 5 mins ago, i hope it didn't break anyting

#

My bad, I found that i was added "Text Mesh Spawner" script by accident to an object in the scene

#

Thanks for warning

Guys anyone know "How can i use javascript function on Unity?" I used them but it gaves my error when i'm building it.

cc0821bb-5961-4e44-9392-ac76ffe7a1fc.png
#

Application dev's gave me JS file to put WebGL's html file for API. I'm using them but when i want to build game it gives error like that. Anyone can help, please. Thanks.

#

Here is my code to call function from Javascript.

image.png
lime patrol
#

Not anyone can help?

mossy snow
#

did you look at the Unity docs for how to do this?

knotty sun
lime patrol
hybrid turtle
#

is there a way to detect whether you are outside the boundary of a mesh skinned renderer

lime patrol
#

Also i have .jslib file on Plugins folder.

image.png
mossy snow
#

your casing is wrong

#

also I don't know much js but those functions are very suspicious looking to me

lime patrol
#

I double checked them they not okay.

latent latch
#

where your intellisense at

lime patrol
#

This is my JS script.

image.png
latent latch
#

not that I've had much help from any ide with javascript

lime patrol
#

Well actually they gave me that js file to put into the html.

knotty sun
lime patrol
#

I just want to reach js functions.

#

I'm exporting game as WebGL.

knotty sun
#

because that is what unity uses to talk to js

lime patrol
# knotty sun because that is what unity uses to talk to js

What about that? ExternalEval method.

public void CallJavaScriptFunction(string jsCode)
    {
        Application.ExternalEval(jsCode);
    }

public void OnButtonClick()
{
    JavaScriptCaller caller = GetComponent<JavaScriptCaller>();
    string jsCode = "trackEventEndGame('game_id');";
    caller.CallJavaScriptFunction(jsCode);
}
knotty sun
#

that is C#

lime patrol
#

Yes it is.

knotty sun
#

yes, so C# calls Emscripten methods which call JS functions, it's not rocket science

lime patrol
#

I mean can't use ExternalEval method to call it?

#

To call JS functions.

#

Or i must use Emscripten?

#

Please forgive me for being confused as this is a topic I haven't dealt with before.

knotty sun
#

iirc ExternalEval died many years ago when Unity dropped JS support

lime patrol
#

and after that they used emscripten for communication?

knotty sun
#

yes, as I have said several times already

lime patrol
#

So what is wrong about here? Documents says put .jslib file into the Plugins folder. I did it.

knotty sun
#

which is correct except your emscripten is malformed

lime patrol
#

I used converter for Emscipten to convert that JS file. As applications dev's send me.

hybrid turtle
#

ok sorry to refine my question how do you find out whether the mouse position has gone beyond the bounds of a MeshRenderer

lime patrol
knotty sun
hybrid turtle
lime patrol
knotty sun
#

no

simple egret
#

Never used that but I assume you need to put your function names in that autoAddDeps call

lime patrol
#

Oh because i didn't put function names to 'autoAddDeps' ?

knotty sun
# 
MyFunction : function() { },
autoAddDeps(MyLibrary, 'MyFunction');
simple egret
#

And yeah I guess you'd need to name them the same as on the C# side, with the uppercase first letter (PascalCase)

knotty sun
#

exactly, this is what exposes the Emscripten functions to C#

lime patrol
#

Got it. Okay right.

image.png
knotty sun
#

one autoAddDeps line per function

lime patrol
#

I hope it's correct now.

image.png
#

After that i'm gonna read emscipten documents to learn what that is..

knotty sun
#

it might help if you did that before trying to use it

lime patrol
#

I change it C# script too.

image.png
knotty sun
#

you are going to have a problem with your id, you cannot use it as you are doing in the js function

lime patrol
knotty sun
#

It's the way C# passes strings, wait one

#

you need to use this in the emscripten function

myId = Pointer_stringify(id);

then pass myId to the js function.
iirc this has been updated in later versions of Emscripten but this still works

lime patrol
#

Like that?

image.png
knotty sun
#

yes, exactly

lime patrol
#

Let me try to get webgl export now. i hope not getting any errors anymore.

lime patrol
knotty sun
#

show the inspector of your jslib

lime patrol
hybrid turtle
#

so i wrote this basic function to detect whether something is in the bounds of my model

# 
        var worldMousePos = Camera.main.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, 10));
        return !flipRend.bounds.Contains(worldMousePos); 
    }```
#

*correction not in the bounds

knotty sun
lime patrol
#

Lastly i need to put that javascript file into the html file?

knotty sun
#

no, that is included in the unity build

lime patrol
#

in application side dev's can access it right?

#

we are iframe webgl game on application.

knotty sun
#

and do yourself a favour, next time someone asks you to do something you know nothing about, tell them to piss off

lime patrol
#

they just told me put that script to html and call it like that...

knotty sun
#

this is not trivial shit, tell your devs they have no idea what they are talking about

lime patrol
#

in application side dev's can access it right?

knotty sun
#

yes

lime patrol

#

i tried to detect mesh collider if it was hit with raycasts but did not work

spring creek
hybrid turtle
#

ok ok sure let me get it

#

here is my method

# 
    {
        RaycastHit hit; 
        Vector3 mousePos = Input.mousePosition; 
        Ray ray = Camera.main.ScreenPointToRay(mousePos); 
        return !(Physics.Raycast(ray, out hit) && hit.collider == foldCollider) || !(Physics.Raycast(ray, out hit) && hit.collider == flipCollider); 
    }```
#

i think this is pretty standard idk what other way to do it

#

excuse the formatting

spring creek
# hybrid turtle ``` private bool CheckInBounds() { RaycastHit hit; Vecto...

So, to break down this return logic. You are checking:
if it did NOT hit something and hit.collider is NOT foldCollider
OR
if it did NOT hit something and hit.collider is NOT flipCollider

Is that what you wanted?
Seems like you would want the opposite

Also, I don't really like doing equality between objects. I try to do tag/layer/trygetcomponent or something like that

hybrid turtle
#

ok thank you ill change the not and use a layer

#

ok even removing the the nots it still doesnt respond

#

I'll use a tag or something then

spring creek
#

@hybrid turtle I would try breaking it up a bit, so you can do debugs in various parts to see which part is working and which isn't

private bool CheckInBounds()
{
    Vector3 mousePos = Input.mousePosition; 
    Ray ray = Camera.main.ScreenPointToRay(mousePos); 
    if !(Physics.Raycast(ray, out RaycastHit hit) 
    {
        return false;  // Hit nothing
    }
    if (hit.collider.CompareTag("Fold") || hit.collider.CompareTag("Flip"))
    {
        return true;  // Hit colliders tagged as Fold or Flip
    }
    return false;  // Hit colliders tagged anything else
}

Not sure which you wanted to be true or false though

No idea, but you are doing a lot of things that arent use. The only thing that is used is moveDir. Also, I really do not thing using a coroutine for the movement of a character is a good idea.

Is it ok?

#

to be on console

cosmic rain
#

It means that you don't catch it. And it would cause undefined behaviour or crash your game

lucid matrix
#

O_o so I just manually check if string is not null or empty and next create new MailAddress()

cosmic rain
#

You should catch/handle it unless you want an emty string to be treated as an unhandled exception

lucid matrix
#

I thought I could some how catch Debug.LogError()

cosmic rain
lucid matrix
#

does Debug.LogError() Throws an exception and can it be catchable? OR is it just printing in console in red text

#

and does not crash script

Hey, I was wondering if it possible to somehow AssetDatabase.AssetPathToGUID() get an asset not by its name, but the value in a variable?

#

the asset is a scriptable object

cosmic rain
#

You need to load it probably@eager fulcrum

What then?

i have a bunch of scriptable objects UnitData, each of them has a variable id

i need to find the UnitData with given id

You nead to load the data from your disk to access it.

#

and then iterate thru them?

cosmic rain
#

If you need to. The method only loads one asset at a time

#

In the example they load a texture, but you can do the same with your SO type

it won't affect performance so much, will it?

Hi All, im doing an assignment where im creating a recreation of pinball in 2022.3 2D, but i am not allowed to use the rigidbody. Im running all of my collisions through colliders and raycasts. Ive currently got nearly everything working, but the piston is running into an issue that when it shoots upwards, the ball sometimes falls into the piston. Does anyone have any good ideas as to how i can keep the ball on top of the piston as it moves upwards?

The ball does all of the raycasts

shy basin
#

ah ok i can definitely do that! do i still need to use time.deltatime in there? i dont usually work in fixed update

leaden ice
#

especially of note is that unless you're doing Physics.SyncTransforms(), none of your raycasts will be in sync in Update

leaden ice
#

so you would continue to use it inside FixedUpdate whenever you need to do that, yes.

shy basin
#

can do! ty

latent latch
#

Why fixedupdate with custom physics though? Is it because of the frame catch-up or however it works when you'd come upon some frame dips?

#

debug the hit

rancid pond
#

hit is working properly

#

I am updating the maintexture using a rendertexture.. is that the reason

leaden ice
#

RenderTexture is NOT a Texture2D

#

You could use Texture instead of Texture2D yes? In which case you don't need as at all

#

just Texture tex = rend.material.mainTexture;

#

also note that rend.material will create a new material

#

if you don't intend that, use rend.sharedMaterial

#

I’m slowly getting there with my physics engine, but the last few decimals are making things not quite work right

#

the issue is iterations and trying to stop on the right position between steps. if anyone has advice

#

what I do now is: I give everything an extra skin (ie + edge radius). Then I take it away when I try to calculate different movements, so when I expand it again, the physics system registers contact

#

the challenge is depenetration and contact, because if I cast when at <= 0 distance to another collider, it frequently registers a hit with wrong normals etc.

#

for depenetration, if I move things to be 0 distance, it immediately registers an overlap for next iteration.

#

but if I do depenetration and casting with some buffer distance, then I get ejected from slopes, then fall down to the side, which causes me to naturally slide down slopes

#

any general advice?

hybrid turtle
#

is it possible to laod two scenes additively and have one scene access the gameobjects of the other?

#

I thought I could just use serializableField but it doesn't allow me to do this exactly

leaden ice
#

the only thing you can't do is direct inspector references

hybrid turtle
#

but i cant the inspector won't allow me

#

to drag and drop from another scene

leaden ice
hybrid turtle
#

ok gotchu

#

is there a work around?

leaden ice
#

many

hybrid turtle
#

idk i went online and it said to use a scriptable object

leaden ice
#

sure that's one option.

hybrid turtle
#

or addressables

leaden ice
#

Addressables are for referencing assets

#

It really depends on exactly what you're trying to do

#

there are many many ways to pass references around

hybrid turtle
#

ok ok like all i need is acess to 3 gameobjects which I want to disable after a timer goes off

leaden ice
#

for a timer, an event is probably the way to go

#

you could even use a static event if it's a one-in-the-whole-game kind of thing

hybrid turtle
#

yeah it is one in the whole game type of thing

leaden ice
#

I would probably also make a single script that is responsible for managing these three objects

hybrid turtle
#

so I could make another class holding the event objects

leaden ice
#

have it listen for the event

#

and disable as needed

hybrid turtle
#

ok ok like an event script?

leaden ice
#

no like a "TheThreeObjectsManager" script

#

dumb name because I only know what you've told me

#

the timer itself would be a separate script

#

and the timer would be the one invoking the event

hybrid turtle
#

yeah ofc

# 
        {
            if (Input.GetKey(KeyCode.Alpha2) && _timerVariable > 0)
            {
                _timerVariable -= Time.deltaTime; // decrement the timer here 
            }
            else if (_timerVariable <= 0)
            {
                EnablePhoneObjects(false); 
                StartCoroutine(FadeVideoCanvas(fadeDuration)); 

            }
            else if (!Input.GetKey(KeyCode.Alpha2) && videoFaderCanvas.GetComponent<CanvasGroup>().alpha == 1)
            {
                EnablePhoneObjects(true); 
                StartCoroutine(FadeVideoCanvas(fadeDuration)); 
            }
            yield return null; 
        }
    }```
leaden ice
#

the manager object would be listening to the event

hybrid turtle
#

like this is all its got to do

#

like not very diffcult but i need access to those objects

leaden ice
#

so instead of EnablePhoneObjects(false); it should be firing events like OnTimerStarted OnTimerEnded

#

it doesn't need to care about the phone objects directly

#

the other script that listens to the events can do that

hybrid turtle
#

ok ok

#

how would i create a custom script editor

#

like event script then?

#

like observer patten?

#

idk

leaden ice
#

you just make an event

# 
public static event Action OnTimerStarted;```
#

To listen to the event you do WhateverClass.OnTimerStarted += MyEventListener;

#

to invoke it you do OnTimerStart?.Invoke();

hybrid turtle
#

ok ok ill write a separate script then to manage those

#

thank you @leaden ice

I'm currently working on a RTS-like building system using a grid. It's a 3D game and the player looks at the world as seen in Picture 1.

This is my code showing a placeholder building. I want it to be right on the grid (local y = 0) and not above or below as seen in Picture 2.

Right now, it sometimes jiggles and behaves like in Picture 3 and like in Picture 2 again.

private void Update()
        {
            Ray ray = Camera.main.ScreenPointToRay(_currentMousePos);
            Debug.DrawRay(ray.origin, ray.direction * 100, Color.yellow);

            RaycastHit raycastHit;

            Physics.Raycast(ray, out raycastHit, Mathf.Infinity, _worldData.BuildingLayerMask);

            Vector3Int gridCoords = _buildGrid.WorldToCell(raycastHit.point);

            Vector3 gridCellCenter = _buildGrid.GetCellCenterWorld(gridCoords);

            debugDisplay.transform.position = gridCellCenter;
        }

Does anyone know a solution to this?

@leaden ice a problem i have with the design of making a object manager script is that there ar eobjects from both scenes that I would need to manage

#

so how would I get all the objects within that script

#

because then it would require two instances to get all references

leaden ice
#

it's unclear to me what's going on. Why there are two scenes in the first place. What these objects are, what the lifecycles of everything are, etc..

like basically I have a scene with a video and another scene loaded additively. And When the timer reaches zero I want to fade the scene in with the video on the canvas in. So basically id need reference to the canvas in the video scene as well as reference to the canvas of the other scene to disable those throughout the transition

leaden ice
#

the only difference is adding the event for the other scene to do its thing

#

you don't need to get all the objects within one script

hybrid turtle
#

yes exactly but i cant get reference to the canvas in the other scene to disable it

leaden ice
#

you don't need to

#

that's what the event is for

hybrid turtle
#

ok ok got you

leaden ice
#

if you really wanted to though you could get direct references to everything using e.g. FindWithTag or the singleton pattern. Or through some mediator object like a ScriptableObject

hybrid turtle
#

ok ok but I'll try an event instead

#

seems like a better design decision tbh

hybrid turtle
#

thank you again @leaden ice got it working the way I wanted

#

hi so I made this function to fade the video in and out of the scene

# 
    {
        print("HAS BEEN CALLED"); 
        var alphaVal = videoFaderCanvas.GetComponent<CanvasGroup>().alpha; 
        float elapsedTime = 0f; 
        while(elapsedTime < fadeDuration)
        {
            videoFaderCanvas.GetComponent<CanvasGroup>().alpha = Mathf.Lerp(alphaVal, 1 - finalAlpha,
            fadeCurve.Evaluate(elapsedTime/fadeDuration));   
            elapsedTime += Time.deltaTime; 
            yield return null; 
        }
        scenePlayer.Play(); 
        finalAlpha = videoFaderCanvas.GetComponent<CanvasGroup>().alpha; 
    }```
#

pretty standard but for some reason it not doing it correctly when I run 1 - finalAlpha

#

i made finalAlpha a global var and initialized it to 0 to begin with

soft shard
# hybrid turtle i made ```finalAlpha``` a global var and initialized it to 0 to begin with

If I understand you correctly, and if your finalAlpha starts at 0, and assuming .GetComponent<CanvasGroup>().alpha starts at 1, your lerp would basically be doing 1 - 0 which is 1, so it wouldnt have any different value to lerp to in that case, then after your while loop your setting finalAlpha to the current alpha value of your CanvasGroup, which I would imagine youd want the other way around

Hey so when i try to make a choice i cant, the game does not detecit my touch. Yet I know I am touching the button because the button changes color when I touch it. How can I fix this? Here is my code, I also put a screenshot of my ink file. https://paste.ofcode.org/6JCVgNEirqSWpGRWRfD5SE

        {
            videoFaderCanvas.GetComponent<CanvasGroup>().alpha = Mathf.Lerp(alphaVal, 1 - alphaVal,
            fadeCurve.Evaluate(elapsedTime/fadeDuration));   
            elapsedTime += Time.deltaTime; 
            yield return null; 
        }
        scenePlayer.Play(); 
    }```
#

to get the same result

leaden ice
hybrid turtle
#

yes that is my bad

leaden ice
#

Also not sure why 1 - alphaVal is being used as the end point

hybrid turtle
#

because basically if 2 is being held down then it should start the timer and fade in but if 2 is not being held down it should not

#

I also have this other coroutine

# 
    {
        while(true)
        {
            if (Input.GetKey(KeyCode.Alpha2) && _timerVariable > 0 && Mathf.Approximately (videoFaderCanvas.GetComponent<CanvasGroup>().alpha, 0))  
            {
                _timerVariable -= Time.deltaTime; // decrement the timer here 
            }
            else if (_timerVariable <= 0)
            {
                EnablePhoneObjects(false); 
                videoFaderCanvas.gameObject.SetActive(true); // need to fade it here careful
                StartCoroutine(FadeVideoCanvas(fadeDuration));      

            }

Normally it is like this! I see the Rect Transform when I work in the Childrens of the Overlay-Canvas

But now, when I work in Editor, i dont see it anymore.

#

ok i got it

south lake
#

So right now I have a script that can pick up objects and set their position in front of the player as if I have "picked up" the object, however this means that you can move objects through walls while holding them. I'm struggling to find a solution where I can 'Pick up' an object and not allow the player to move it through walls (e.g it gets dropped automatically if the player were to try and move it through a wall) I can send a video if that helps explain the issue

void basalt
#

you could do something similar

south lake
#

Yeah that's sort of what I'm looking to do

#

Will give that a go

void basalt
#

The only problem is that it might lag behind the player while you're running

#

and it wont look like it's grabbed

#

when you drop the item, you could always just have it respawn at the player's origin, then add force infront of the player, so he's like throwing it

#

then do some camera stuff so that the grabbed object always renders first before any walls or obstacles, so that the visual appearance doesn't clip through

south lake
#

To be fair I don't mind if the object lags behind a little, I tried some stuff with spring joints but they seemed to be a little too chaotic for what I was aiming for

#

Same thing with configurable joints, it stopped the object going through walls but if I forced it too hard the object seemed to get stuck until I touched it

void basalt
#

is your player a rigidbody?

south lake
#

The player uses rb movement ye

void basalt
#

good

south lake
#

I prefer rb over character controllers

void basalt
#

you'll want to scale the velocity based on the difference of the actual hold item's position vs where it needs to be

#

so if it's right infront of the player, you want less velocity. If it's further away, more velocity so it moves where it needs to be

south lake
#

I mean that's sort of what a spring joint does, but that didn't seem to be quite right

void basalt
#

I can't speak for physx joints. You'll pretty much always get a better result by doing your own hand-tuned method

soft shard
# hybrid turtle nothing in update just this other coroutine

Assuming your hold logic isnt causing weird issues of possibly calling your coroutine more than you intend, and if your fade coroutine is the same, try logging the params of your lerp, and moving the elapsedTime change to happen before your alpha change

lean sail
south lake
#

I did a little bit of adjusting with it but most of what I did was either not enough force (dragging across the ground too slow) or too much force (literally orbiting my player lol)

#

I can't seem to find the right spring/dampen ratio

void basalt
#

springs really aren't going to give you the desired result.

south lake
#

Yeah it's close but not quite it

lean sail
#

Dragging across the floor is more of a friction issue than it is a joint one. If you do this manually through script, you can just assign the velocity directly to get around that

void basalt
# 
float multiplier = 1;
vector3 desiredVelocity = (grabbedObject.position - targetHands.position) * multiplier
#

I imagine it would be as something as simple as this

#

you'll have to mess around with the multiplier value

#

disabling gravity on the target object would also help. you might not even need a multiplier

south lake
#

disabling gravity is probably a good idea for while I'm holding it, I have no idea why I didn't think of that

void basalt
#

you'll probably also want to lock the rotation

#

otherwise it's gonna spin like it's levitating. could be cool though

lean sail
#

You could set some angular drag on it too, which would slow rotations down

south lake
#

Thank you both! This is much more what I was looking for, it no longer clips walls and looks smooth when moving the object! UnityChanThumbsUp

Im just starting out and this might be an obvious thing im missing but my movement works, but the issue is the up and down arrow keys litteraly move the cube up and down and the physics also seem iffy, anyone got any suggestion?

With big I mean big relative to the default gravity scale

fleet carbon
#

Ahhhh that makes sense, thank you!

dusky lake
#

If you see a big tower fall in real life its also "slow" compared to a tiny wood brick you push over, imagine it the same way

#

stay in the 1x1x1 scale for objects as a reference, and it wont feel slowmotion 😄

fleet carbon
#

Hm it seems to not make a difference lol im genuinely stumped

dusky lake
#

is your cube now 1x1x1?

fleet carbon
#

Yea

dusky lake
#

Can you show us a video?

fleet carbon
#

Yea one sec

dusky lake
#

oh, you are setting its vertical velocity to 0 every frame 😄

#

instead of 0 set it to playerbody.velocity.y

fleet carbon
#

Thanks ill try that now

#

It fixed it but somehow got a whole other issue now, the cube just flies away as it hits the ground lmao

dusky lake
#

Time for the next video i guess 😄

fleet carbon
#

Yeap lol thanks for the help

#

Idk how this even happened haha

#

WAIT

#

Nah ik

#

Made a dumb mistake

#

I think atleast

dusky lake
#

Your plane lost its collider? 😄

fleet carbon
#

Nah apparently not I thought it might be that haha

#

Its not that so who knows now lol

dusky lake
#

nvm, forget what i wrote before, would have a different controll feeling

fleet carbon
#

That actually fixed it tbf lol

dusky lake
#

yeah, but now you add the velocity instead of setting it

fleet carbon
#

Yeah

dusky lake
#

now your cube will behave like a boat on water that you try to steer into another direction

#

instead of taking that new direction instantly

fleet carbon
#

Yeah

#

I just got a warning

dusky lake
#

Ok following:

Make the hmove and vmove modifiers class properties and set the velocity in FixedUpdate instead of update

#

oh they actually already are, you just shadow them locally 😄

# 
public class Playercontrol : MonoBehaviour
{
    public float speed = 10f;
    public Rigidbody playerbody;
    private float hmove;
    private float vmove;

    // Update is called once per frame
    void Update()
    {
        hmove = Input.GetAxisRaw("Horizontal");
        vmove = Input.GetAxisRaw("Vertical");
    }

    private void FixedUpdate()
    {
        playerbody.velocity = new Vector3(hmove, playerbody.velocity.y, vmove) * speed;
    }
}```
fleet carbon
#

Im confused now there is no movement at all lmao

dusky lake
#

did you replace the update function in your code?

#

like remove the var infront of hmove and vmove

fleet carbon
#

Wait its working now lol think I forgot to save the code

#

Okay it just jolts off the plane now and out of camera veiw

dusky lake
#

without you pressing anything?

fleet carbon
#

Nah thats with pressing

dusky lake
#

reduce speed 😄

fleet carbon
#

By even more? damn 😆

dusky lake
#

i mean you are setting the velocity to 10units/s

#

if you have a 1x1x1 cube thats out of screen pretty fast 😄

fleet carbon
#

Yeah thats fair haha

#

Doesnt seem to fix it damn

#

It just shoots upwards

#

Like it moves for a second then shoots lol

dusky lake
#

I am not sure if reapplying the velocity every frame might create problems, ill test a bit

fleet carbon
#

Oh wait angular drag at 0.5 seems to fix it lol

#

Well kinda

dusky lake
#

nah thats just how much rotation slows down by "air drag"

fleet carbon
#

Ohh

#

The way it shoots up is actually kinda funny, but yeah this is me increasing the speed

#

Even then it moves strangely haha

dusky lake
#

ok i can recreate the problem for sure 😄

#

OHH

# 
        playerbody.velocity = new Vector3(hmove * speed, playerbody.velocity.y, vmove * speed);
#

we were multiplying the whole vector by speed

#

meaning also the updward velocity the cube had. every. frame.

#

that line above should fix it

fleet carbon
#

Ohhhh

#

Thanks so much haha

dusky lake
#

thats why you couldnt force the bug on 1 speed

fleet carbon
#

AHH

#

Yeah thats fixed it

dusky lake
fleet carbon
#

Oh yeah taht looks spiffy

dusky lake
#

also add this to the first line of FixedUpdate:
if (Mathf.Abs(hmove) < 0.001f && Mathf.Abs(vmove) < 0.001f) return;

#

so the cube can move on its own while you dont move it via keyboard

fleet carbon
#

Ahh thanks man

Hello everyone. I am making something like a 3D RTS and I need to create a Fog of War. As I understand the best way for me is to use some shader for this purpose. But I do not fully understand how to create it... The additional problem is that the game is in 3D with free camera, so Fog of War should work for different angles of camera
Any ideas or advices on that problem?

So, I "updated" the navmesh from the "NavMesh Updater" and it put these NavMeshModifiers everywhere, and I want to get rid of those that are in unneccesary places, but whenever I try to get the component NavMeshModifier in a script, it says no such type or namespace exists and the latest docs are from 2020.3 for "NavMesh Modifier"

#

So I don't quite know what namespace I'm supposed to use or what I'm supposed to do to remove them

I'm making a grid based puzzle game and I'm trying to scale it for every device by using Aspect Ratio Fitter and "Scale With Screen Size" on the canvas but sadly when I use the game on a phone the game objects get put outside of the grid and I'm not sure why. The grid is based on every cell being a prefab with a set cell size.
Does anyone know why this happens?

The height of your screen will always be twice the size of your camera. That means that the height is fixed and extra space is added or removed on the left and right.

But I assume that's not what you want for your game. It would be better if it were reversed.
So you need to change the orthographicSize of your camera depending on the phones apect ratio:

Hey, how's it going? Could someone help me out? I'm working on a college assignment, and I need to create a multiplayer game using the proxy design pattern in Unity. Does anyone know how I can do this or have any ideas?

# loud wolf Hey, how's it going? Could someone help me out? I'm working on a college assignm...

I unfortunately haven't begun to learn about the multiplayer APIs you can use with Unity yet. If you are new to Unity I'm not sure mastering the appropriate skills will be doable for most folks within a semester. BOSS ROOM was a Unity-made example of a small coop type game. I haven't personally attempted to use it in the newer Unity versions yet, but with the appropriate version installed it may be a good starting point to learn and understand the basics.

No, it isn't something I'd heard of before. Googling it made it sounds like just classes with interfaces.

loud wolf
exotic aspen
#

Yeah sorry I don't have more info here. My approach might be to take the coop sample and replace the assets/mechanics a bit. Maybe implement Tic-Tac-Toe with your avatars in there or something unique. Then wrap all the calls to make it Proxy-like. I'm guessing you had some instruction on what that methodology is...? so you'd be further along on that angle.

How would I check whether two convex polygons are connected? By connected I mean that at least one edge on one polygon is touching another edge on the other polygon. I've tried many things and gotten something almost working, but it seems to often still be really inaccurate. The current almost working code is the following:

    private bool IsConnected(Vector3[] verticesA, Vector3[] verticesB){
        for(int A1 = 0, A2 = 1; A1 < verticesA.Length; A1++, A2 = (A1 + 1 == verticesA.Length) ? 0 : A1 + 1){
            for(int B1 = 0, B2 = 1; B1 < verticesB.Length; B1++, B2 = (B1 + 1 == verticesB.Length) ? 0 : B1 + 1){
                if(PointOnLine(verticesA[A1], verticesA[A2], verticesB[B1]) &&
                   PointOnLine(verticesA[A1], verticesA[A2], verticesB[B2])){
                    return true;
                }
            }
        }
        return false;
    }
    private bool PointOnLine(Vector3 pointA, Vector3 pointB, Vector3 checkPoint){
        Vector3 direction = pointB - pointA;
        Vector3 check = checkPoint - pointA;
        float dotProduct = Vector3.Dot(direction, check)/direction.magnitude/check.magnitude;
        if(AprxEqual(dotProduct, 1f)) return true;
        /*direction /= Mathf.Max(direction.x, direction.y, direction.z);
        check /= Mathf.Max(check.x, check.y, check.z);
        if(AprxEqual(check.x, direction.x) && AprxEqual(check.y, direction.y) && AprxEqual(check.z, direction.z)){
            return true;
        }*/
        return false;
    }

The problem however is that it gives a ton of false positives, no false negatives as long as the AprxEqual tolerance isn't very very small tho.
And yes, this is in 3D, but the vertices have already been converted to world space and all of them are on the same plane.

try remove the () first

#

since it is function call and testaction returns void

hoary sparrow
#

I sadly get the same error

#

just "cannot convert from method group to object"

fervent furnace
#

use overload methods (parameter type action or ienumerator), i havent tried convert something to c# object before

hoary sparrow
#

alright, will test that out

fervent furnace
#

and create a struct

struct whatever{
Action action;
IEnumerator enumerator;
}
```instead of just using object and cast it to see what the object actually is
hoary sparrow
#

basically, for this system I am creating a queue of actions and enumerators that then gets fired sequentially, so the overload solution you mentioned should be fine
thank you for the help!

Is there a way to see what is being used the hood for things like Stack and Queue class in C#?
Like for example, are they just arrays, or LLs?

fervent furnace

read the source code

Yeah, trying to find that. I see on MS docs that Stack is an array.

But trying to locate more info.

what is your guys opinion on using gameobject names for information, for example, I want a specific animation to be used for diferent objects, and I didn't want to make a script for each object to identify it or using tags, so I was thinking of using the gameobject name to define the name of the animation trigger?

#

but this is a bit sketched right?

dusky lake
#

thats 100% sketch

woven matrix
#

fuck it I am gona do it anyway, the gameobjects are blank gamepbjects that are called "leftLeanSpot" and "RightLeanSpot"

#

and they are part of a parent that is called resting spots

#

so I guess it wont fuck my mind that much

dusky lake
#

Just attach a script that has a property "name"

woven matrix
#

but wont that give more load to the program?

#

having a script for each spot?

#

thats my question, because I am gona have allot of "Spots"

dusky lake
#

unless you are handling thousands its no problem

woven matrix
#

yeah, there is gona be kinda a few, I am trying to do a small city

#

and npcs will interact with the spots

dusky lake
#

just accessing a property of a script is basically no load

#

might be the same as accessing the name of the gameobject

For the most part yeah, though just now z is just hitting 0.01

then add logs along the way, check if the input actually gives you what you want, if that does check the next step and so on, or even better use the IDE debugger for that if you know how to

You could start from placing the cars randomly but in a solved state. Then just move them backwards in random order to get an unsolved puzzle. I guess.🤔

I have a class that inherits from Abstract class (Let's call this class X, let's call the base class Y). I call OnProductFinished in the update function in the base class. My question is; Now I override OnProductFinished in the same way in my class that inherits from Abstract class. Which OnProductFinished works logically? The base one (OnProductFinished in Y?) or the one in the inherited class (OnProductFinish in X)?

I do not understand your question, however note that when you call a function, the most specific one will be called.

When a virtual method is invoked, the run-time type of the object is checked for an overriding member. The overriding member in the most derived class is called, which might be the original member, if no derived class has overridden the member.

If I don't do the procedural generation do you think it would be viable to make 500ish prefabs and then have a script call each one in order to a scene and then once they are solved just destroy the prefab and then call the next one. I want to make it seamless, I wouldn't be opposed to generating a level online and then just recreating it myself after having all the systems set up. I'd say 500 would be good amount of levels to start but what do you think. The procedural generation would be way more chill but i just have no idea how to implement this

steady moat
#

Oh, you mean 500 levels.

#

There is no reason to use prefabs per level. I think you should use a script to generate your level. I would create a ScriptableObject that defines how the level should be constructed. (You could even create an importer base on the data you are going to generate from the site)

#

This way, you are going to be more flexible. By example, you could easily swap the assets (Board, Car, etc.) to tune your game.

generation gets me excited sooner i can master it sooner i can use it to generate infinite levels of any type of game

hello I want to make a 2d pixel art top down game and I want to make a big but not infinite procedural world, I want main landmarks on the map to be spawned in random locations and the rest of the world will be roads and forest areas

#

should i use a mix of tiles and prefabs or prefabs alone or tiles alone

steady moat
craggy oyster
#

i havent made any assets or worlds thats why im asking to know how to start making the procedural worlds

steady moat
craggy oyster
#

yes

steady moat
#

then use tilemap

craggy oyster
#

can tilemaps have functionality?

steady moat

like per say a tile that can randomly spawn a grass pedal that moves or a tree that can be chopped down

craggy oyster
#

ok ok so gobjects can be placed on tiles

yes

#

alr what about landmarks like if I wanted to make a big mall in the game

can I make a tile that spawns the object of the mall and fits correctly

steady moat
#

That is, if you want your world to be grid base and use the functionnality of tilemaps. (I would copy the data from one tilemap (mall) to the other (world))

well I think you dont get my question

#

Im placing all these tiles through code

#

basically using the grid system of tilemaps to spawn these tiles

#

and I want to know how a tile i place can have for example children objects on it that are gameobjects

steady moat
#

It is not part of the tilemap

craggy oyster
#

aha see

steady moat
#

See what ?

craggy oyster
#

thats my question so the procedural world Im making isnt fully using the tile system

#

I will have to place objects through code irrelevant to the tile grid

steady moat
#

probably

#

You could always make a tile that represent the object

#

However, the object will need to fit a tile exactly

#

You could have two tilemaps layer

#

One with the ground/wall, and one with the dynamic object such as chest or tree

#

There is multiple way of doing, depending on what you want and what you do those come with restriction and ease of use.

craggy oyster
#

im starting to understand

#

I just have to see how object tiles work

#

and then I think i can make a plan

Interface Segregation Principle

https://en.wikipedia.org/wiki/Interface_segregation_principle

Interface segregation principle

In the field of software engineering, the interface segregation principle (ISP) states that no code should be forced to depend on methods it does not use. ISP splits interfaces that are very large into smaller and more specific ones so that clients will only have to know about the methods that are of interest to them. Such shrunken interfaces ar...

hard viper
#

I don't understand

#

I get it, but not how it applies here

#

Class1 and Class2 both make heavy use of the getters and setters of a large fraction of fields

steady moat
#

In other words, all other object shouldnt contains a direct reference to Class2. Instead, they should use interface that Class 2 implements

hard viper
#

I would say something like, Class2 has like half of its fields that should only be accessible to Class1 and 2

steady moat
#

Also, this is really a small that you have such a high coupling with a single class

#

Your cohesion must be really low in this given class

hard viper
#

correct, so I want to break it up now before it gets worse

steady moat
#

I guess, you could try to read on Single Responsibility Principle

hard viper
#

I'm thinking about breaking up all the shared fields into a single intermediate class, and composing it into class2. My concern is that we still have access

#

I want to do that, honestly. I just don't know how to get the final product to be encapsulated like how I want

#

I don't want to half-ass the encapsulation, basically

#

If there were access modifiers that only allowed access to specific classes (like the friend keyword), then I think this would be trivial

#

this might be hackey, but could I define Class3 with a bunch of internal methods, and make it a partial class, partially defined in Class1 and in 2?

steady moat
#

Personnaly, I refactor this way:

  • Divide the code in #region / #endregion blocks
  • Extract the actual code in an other class (Class2A) and rewire every function call to this new class. (You would have a bridge between Class2 and Class2A)
  • Remove any call to the given function of the original class to use the new class (The call would looks like Class2.Class2A.MyFunction)
  • (Optional) Move the given class to a more appropriate place such as a ServiceRegistry or a higher(concept wise) class
hard viper
#

I can do that without issue tbh. but wouldn't other classes still be getting access?

assume I can actally extract exactly like you described

Hi, I'm building a house building game and I'm trying to figure out the position to place a wall so it aligns with another wall even if one of the walls are rotated. I was able to do this without rotation. But now that I'm trying it with rotated walls, I'm not sure how to calculate the position of the wall I'm looking to place. If the wall already on the ground has a rotation than the default, then I have to change the position of the wall I'm placing than using the default

hexed pecan
#

You can rotate the offset from the first wall too by multiplying it with the first wall's rotation

vernal wharf
#

This is my object placement code

dusky lake
vernal wharf
dusky lake
#

Ohh so now you want the new placed wall to have the same rotation as your pre-placed wall, when snapping to it?

vernal wharf
#

I'm able to get the same rotation. It's the position of the new wall I'm not sure how to calculate if the position of the wall already on the ground is rotated

rocky helm
vernal wharf
#

I've never heard of that

rocky helm
#

So like ```cs
toPlaceWall.position = toSnapWall.position + toSnapWall.right * wallWidth

toPlaceWall.rotation = toSnapWall.rotation

vernal wharf
#

But that's only for the x axis?

rocky helm
#

On the local x axis of the wall that we want to snap to

#

Not the global x axis

dreamy elm
#

Is there a way to get the picture that shows the prefab in the project menu?

rocky helm
vernal wharf
#

@rocky helm I'm trying that my friend

#

That works better than what I had @rocky helm 🙂

#

But if the wall is rotated, the new wall jumps multiple positions but is pretty cool when I apply it

#

I don't know if that's a range issue

#

For example, my players placement rangement or the snap points

#

Works fine if the wall already placed isn't rotated

# 
parentTopLeft.transform.position = parentOtherObject.transform.position - parentOtherObject.transform.right * size.x;
# 
                if (otherObject.tag == "TopRightSnapPoint")
                {
                    Debug.Log("hello1");
                    renderer = GetComponent<MeshRenderer>();
                    size = renderer.bounds.size;
                    size = new Vector3(size.x, 0, 0);
                    Debug.Log(size);
                    Debug.Log(topLeft);

                    GameObject parentTopLeft = topLeft.transform.root.gameObject;
                    parentTopLeft.transform.position = parentOtherObject.transform.position - parentOtherObject.transform.right * size.x;
                    parentTopLeft.transform.rotation = parentOtherObject.transform.rotation;
                }

Actually when I put the radius very high, the wall gets placed in the same position as the first wall

Alright so I just finished adding reverse shadowmapping to my 2D RTS for line-of-sight fog of war removal. And as expected, its consuming a lot of CPU cycles. I've already optimized the routine itself rather heavily. And NPCs only perform the check if, on an AI tick, they are no longer on the same tilemap tile they used to be. But when moving a lot of NPCs at once everything spikes. I'm curious what optimization techniques might be possible here. I couldn't think of an efficient way to notice nearby NPCs had already done the LOS check and to ignore doing it again, for example.

Trying to use root motion atm on my character. Noticing a weird thing where my values (Lateral, forward) seem to constantly be changing in the animator and causing the character's animations to kick in some times. Like walking forward without any input from me.

Anyone have any ideas where I'm going wrong?

Code is too big for discord limit apparently so I just paste linked it

@rocky helm Is that what you need?

WallConnect has the snapping code

Do you want to voice chat or is text better?

rocky helm
#

So, I might have found something, although if that is true then I don't even get why it works in the other cases.

#

Every update, you either instantiate a new object or make the current object snap, correct?

vernal wharf
#

I only instantiate when the player presses the left mouse button

#

and I only snap if 2 sphere colliders are touching

# 
        void Update()
        {
            // TOP LEFT 
            Collider[] topLeftColliders = Physics.OverlapSphere(topLeft.position, radius);

            // Loop through the colliders to perform actions with them
            foreach (Collider collider in topLeftColliders)
#

Oh

#

There's another radius there

#

Interesting..

Oh no, same problem after changing it

Well then this code part has me really confused

                if (CurrentObject && playerController.isPickingUp == true)
                {
                    CurrentObject.useGravity = true;
                    CurrentObject.transform.gameObject.GetComponent<WallConnect>().enabled = false;
                    Rigidbody CORB = CurrentObject.GetComponent<Rigidbody>();
                    CORB.constraints = RigidbodyConstraints.FreezePosition;
                    CORB.constraints = RigidbodyConstraints.FreezeRotation;
                    CORB.isKinematic = true;
 
                    CurrentObject = null;
                    playerController.isPickingUp = false;
                    return;
                }
                else if (playerController.isPickingUp == false)
                {
                    // Instantiate the object at the hit point. 
                    GameObject newObject = Instantiate(objectPrefab, PickupTarget.transform.position, Quaternion.identity);
                    CurrentObject = newObject.GetComponent<Rigidbody>();
                    CurrentObject.useGravity = false;
                    Rigidbody CORB = CurrentObject.GetComponent<Rigidbody>();
                    playerController.isPickingUp = true;
                    newObject.GetComponent<WallConnect>().enabled = true;
                    //CORB.constraints = RigidbodyConstraints.FreezePosition;
                }

This is running in Update, and every update, if the player is holding down the left mouse button and isPickingUp is false then it creates a new object and sets isPickingUp to true, but the next time Update fires it sets CurrentObject as null and sets isPickingUp to false, which would trigger a new object being made no?

vernal wharf
#

Only sets CurrentObject to null if the player press the left mouse button again

#

One click for spawn, another click to drop

rocky helm
#

Oh shit mb. I forgot how the input system worked for a moment

#

Yeah that makes a lot more sense

vernal wharf
#

Hehe, I'm still learning myself 😛

rocky helm
vernal wharf
#

Yeah, only if the first wall is rotated about 90 degrees

#

if it starts at another angles, usually works fine

#

And if it's at 90 degrees, the wall sometimes gets placed into the same position

#

Putting 2 walls in 1 position

#

It's almost good except for that edge case

Does using a struct for existing GameObjects/ Unity Components make sense? Does it copy the object and make it redundant?

Oh

@rocky helm It works now

river shale

Idk what level of code this is lol, but I want to know if theres a way I can use a character controller to manage player movement while still using the rigidbody to apply forces to the character.
This is the code im using to move the player

playerController = this.GetComponent<CharacterController>();
playerController.Move(moveDirection * Time.deltaTime * moveSpeed);

But I want to be able to apply forces to the players rigidbody and have it move the player. This dosent work at the moment because I think every time you call the character controllers Move() function it sets the velocity to 0 (or something along those lines)
Any ideas?

I did what you did was increase the radius after placing the object. But then I had to update this radius to the new radius:

If I want the player to move in the direction the camera is facing what should I do to achieve that, i've tried a few things but haven't been able to figure it out or have gotten close

I know im probably doing it all wrong or missing a vital thing

How do I get this simlpe code to work on my Android build?
It works perfectly fine in the editor, but not after being built.

string path = Application.dataPath + "/" + "Resources/example_mesh_0.ply";
var stream = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.Read);
var header = ReadDataHeader(new StreamReader(stream));
var body = ReadDataBody(header, new BinaryReader(stream));
rigid island

#

And use some using statement for those streams, to make sure they're closed properly whatever happens!

dusky lake
#

using is the automatic version of calling Close on them after the code block right?

rigid island
#

yup

#

you dont even need encapsule in code block with using

simple egret
#

Yep it calls Dispose which internally closes the stream

#

Available to use on anything that implements the IDisposable interface

# fast hound Ah, Application.persistentDataPath didnt work 2023/11/05 15:16:19.747 28162 281...

you need to:

  1. move the file from Resources folder into a StreamingAssets folder, since Resources gets baked into asset files and won't be available
  2. use the streamingAssetsPath as source dir
  3. Open the file using UnityWebRequest, since it's actually packed into the jar and isn't inthe file system still
    see https://docs.unity3d.com/Manual/StreamingAssets.html and https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequest.html

so i have made this code for the player movement but the player keeps falling on to no where even though ive added rigidbody and enabled gravity

{


    public CharacterController controller;
    public float speed = 12f;
    public float Gravity = -9.81f;
    public Transform GroundCheck;
    public float GroundDistance = 0.4f;
    public LayerMask GroundMask;
    public float JumpHeight = 3f;

    Vector3 velocity;
    bool isGrounded;

    // Update is called once per frame
    void Update()
    {
        isGrounded = Physics.CheckSphere(GroundCheck.position, GroundDistance, GroundMask);
        if (isGrounded && velocity.y < 0)
        {
            velocity.y = -2f;
        }


        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");


        Vector3 move = transform.right * x + transform.forward * z;

        controller.Move(move * speed * Time.deltaTime);

        if (Input.GetButtonDown("Jump") && isGrounded)
        {
            velocity.y = Mathf.Sqrt(JumpHeight * -2 * Gravity);
        }

        velocity.y += Gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);

    }
}```

is it the code problem or i missed to do smth

dusky lake
#

Yeah so gravity is active, shouldnt the player fall?

dusk wolf
#

but not more than the plane

dusky lake
#

Also if you have a rigidbody with gravity, you dont need to manually set the y velocity

#

does your player + the plane have colliders?

dusk wolf
#

no

dusky lake
#

then read about colliders 😄

What do you mean by this?, not sure if I worded the question right tbf haha. What I am looking for is a way to make it so the player moves in the direction that the camera is looking like in may first person games. I had this working before but cant seem to figure how to do it again

#

Im not sure if Im misunderstanding your message

Ohhhh right thanks!

I apologise for these questions btw haha, I'm really new to unity atm and I realise I should have posted in the beginner code channel 😁

    return ret;
}```

Hello, this is a simplified version of my tooltip code, why does this not work on different aspect ratios? recT is the RectTransform component of the tooltip. All this is executed on a Canvas. This only works correctly on 1920x1080.

is there any way to use an Event Trigger component on a 3d object?

somber nacelle
#

yes, it needs a collider and your camera needs a physics raycaster

tawny elm
#

i could use the collder's OnMouseEnter thing but id have to make a new script just for detecting that object and i dont really want to

tawny elm
#

i saw tutorials doing the same sort of thing but they did way more complicated things

#

thats poggers

I'm seeing inconsistency in my cast methods. Can someone explain to me: if I Cast colliderA (Collider2D), I hit colliderB with hit distance = 0.0055 (positive). Then if I immediately call colliderA.Distance(colliderB), the distance is -0.00999 (negative). That means colliderA and B are already overlapping and 0.00999 units deep in each other. Can someone explain how these two things can make sense?

#

how can both be happenning at once?

dusk apex
#

Maybe show your implementation for "I hit collider B with hit distance".

hard viper
# 
                    Debug.Log($"When casting {mover.name} farther, we hit {x.collider.name} at {x.distance} hit raw (distance = " +
$"{x.collider.Distance(mover.mainCollider).distance}).");}```
#

this formats so poorly on discord. hold up

dusk apex
#

So x is the raycasthit info

hard viper
#

the RaycastHit2D is generated by this line:
colliderToCast.Cast(castVector, receiveForceFilter, raycastResults, distance);

#

yeah, I only used a shitty variable name for quick testing purposes. to see why my other things were not working

dusk apex
#

Distance would return the distance of the two objects

hard viper
#

correct

#

so why is distance negative (=overlapping/penetrating), while the raycasthit2D gives a positive distance

dusk apex
#

Ones a raycast, the other is a difference of position

#

The raycast would be from origin to impact point

hard viper
#

yes, but if we're overlapping, shouldn't the hit have hit.distance = 0?

dusk apex
#

Distance would be between the two objects. The results shouldn't be the same unless both objects have no volume.

hard viper
#

I understand... but how can one be negative, and the other positive?

#

I would expect negative distance + zero hit distance, or both positive

#

because if the Distance is negative, and we cast the whole collider, then we're already on top of each other

dusk apex
#

0.0000000000001 and -0.00000000000000000000000000001 aren't too different

hard viper
#

I kind of need this to be exact for my purposes

#

exact to within 10^-6

dusk apex
#

But ignoring that, the raycast hit distance and difference in position (Distance) aren't measuring the same thing

#

Raycasthit evaluates relative to origin and impact point. Distance evaluates relative to origin and origin

hard viper
#

I understand they aren't measuring the same thing. But explain how you can have negative distance and positive hit distance

#

just HOW does that happen

#

do you understand what I'm getting at?

dusk apex
#

Are they exactly at the same position?

hard viper
#

by Distance, they should already be penetrating into each other

dusk apex
#

For example, at vector zero of the world in position.

dusk apex
#

And if not zero in distance, a raycast impact point will not simply yield the difference in position of the two objects.

hard viper
#

but I expect the raycast to have actually zero hit distance automatically if the shapes already overlap

dusk apex
#

Are they at the same position?

hard viper
#

that's kind of an abstract question, because they are different shapes

dusk apex
#

Trying to make you not use the overlap word here as it isn't remotely the close to being same thing

hard viper
#

I can't define an area by a single point

dusk apex
#

Area doesn't matter

#

Distance define the difference between the two origins

#

Raycast distance will yield the nearest impact point

hard viper
#

but for colliders, it should be the negative of the magnitude of the smallest vector to eject them out of each other (if distance is negative)

#

like, if I have two circles of radius 10 with their centers at 0 and 10, the distance should be -10

night harness
dusk apex
#

They're two different measurements that you're doing.
Origin to impact point and origin to origin. For them to be the same, the impact point needs to be the origin of the other object.

hard viper
#

but how do you even define impact point between two shapes that are already penetrating inside each other?

#

not even touching at a single point. there is a whole area of points overlapped by both shapes

dusk apex
night harness
#

Oh apologies, wasn't aware raycasthits had a built in distance value

#

my L

dusk apex
#

Yeah, I skipped over that as well UnityChanSorry

hard viper
#

when you use .Cast on a collider instead of an actual ray, the interpretation is a little bit different

hard viper
#

ok,when casting the collider, it's like the collider is just smaller?

night harness
#

could that just be floating point imprecision?

hard viper
#

absolutely not
