fixed it by changing the raycast origin point

[nocturne kayak]

Hey, back with the same old problem, cutting straight to the point- i'm trying to achieve a transform similar to the transform you get in the editor, but in-game

so far i managed to cook it up, the cube's moving on xy based on the mouse position

i also made some basic scripts for the handle which basically tell me if someone clicked on the axis handler or not

but i can't for the love of me figure out how to implement drag axis to drag cube

[wet bobcat]

Im setting up a VR-project with ambisonic sound (360 surround) and want to know...

where objects are in relation to where the player faces...

...so I can pan the sound of the objects in external software.

How can I go about to get a value that represent this, that I can convert to degrees, what solution/technique shall I use? Dont know where to look atm.

[nocturne kayak]

dot product will help you see how close to the sound source the player's looking at

Quick vector subtraction will tell you the distance

correction: dot product will tell you if the source's behind or in front of the player, 1 is directly in front, -1 is directly behind

[rocky canyon]

once u click on handle you could use the mouse position + raycast and project on plane to the plane parallel to the handle and then just use the delta to move the object around

[nocturne kayak]

That makes sense, how would i set up a virtual plane at the handle position?

also, wouldn't defining a plane make it so i can move it on both x and y axis of that plane?

nvm,you're talking about a plane parallel to the cam?

[wet bobcat]

How can I see left or right panning placement? Can you please point me to a script or tutorial that shows this. I am installing the project on saturday.... I really want this to be a part of it.

[rocky canyon]

https://paste.myst.rs/v39ev94z this is for a camera scrolling system

for a top down map style cam controller.. but ```cs
if (Input.GetMouseButtonDown(0)) {
Plane plane = new Plane(Vector3.up, Vector3.zero);

        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

        float entry;

        if (plane.Raycast(ray, out entry)) {
            dragStartPosition = ray.GetPoint(entry);
        }
    }```

im guessing its similar to that

[nocturne kayak]

I wouldn't know of a tutorial\script to point you to, sorry

but it'd involve a bit of vector maths, which i'm rusty on, unfortunately

basically subtract playerpos fom soundsourcepos relative to the playerpos

[willow scroll]

Not sure what this means, could you elaborate, please?

[nocturne kayak]

if the result's positive, it's on the player's left, negative means player's right

[rocky canyon]

i guess ud just use the cubes forward, right, or up and then the cubes position

[wet bobcat]

I have several obects in a scene that the player (with VR-headset) can interact with. When the player turns around, or move the objects, I want the objects sound sources move accordingly. So I can pan this around in a 7 speaker circular setup. I use external software for synthesis (PureData). I just want a value for each object in the scene that represents its position (in relation to the player) in something similar to degrees. Then I send this out over UDP/open sound control. Everyhing is working OK, except panning. Please tell me if I should clarify.

[willow scroll]

Thanks for the explanation. I am sorry, I am not familiar with VR

[wet bobcat]

It should be the same, its just compared to the player camera position

[nocturne kayak]

I'm trying to wrap my head around it

[willow scroll]

How would you represent the position in degrees?
If you try to think of it as a degree distance from the direction of the camera to the player, there will be a possibility of the objects in the same "line" having the same value

[nocturne kayak]

Jeus christ this is so frustrating

i just want to manipulate objects ingame like you would on the editor

[jolly urchin]

What's causing this 😭

I'm losing my mind I can't figure it out

[willow scroll]

First of all, they are supposed to be paths, not pixels

[rocky canyon]

ya, tbh not a straight answer comes to mind..
thats the kind of thing i'd just have to tinker w/ to figure out

[willow scroll]

Doesn't it literally tell you?

[jolly urchin]

I don't know how to do what its telling me

[wet bobcat]

If I get a value that is 0 if it is in front of the player, 1 if it is on the right, 2 behind, and 3 if it is to the left then I am set. The distance does not matter

[rocky canyon]

thats when you break it into pieces.. and figure out how to do the thing u dont know how to do

[edgy prism]

Hello this might be some sort of quirk of unity but in case its not I would like to understand whats causing it. Im checking positions on my grid in 2D and when I change the float in my IsPositionOccupied function to 2.5 and get to a gamestate where the code is being run Unity consistently freezes

Vector2 spawnPosition = Vector2.zero;
        bool validPosition = false;

        while (!validPosition)
        {
            spawnPosition = new Vector2(Random.Range(-3, 3) + 0.5f, Random.Range(-8, 7) + 0.5f);
            validPosition = !IsPositionOccupied(spawnPosition, 2f);
        }

        // Add position to reserved list
        reservedPositions.Add(spawnPosition);

bool IsPositionOccupied(Vector2 spawnPosition, float radius)
    {
        foreach (Vector2 reservedPos in reservedPositions)
        {
            if (Vector2.Distance(spawnPosition, reservedPos) < radius)
            {
                return true;
            }
        }

        Collider2D overlap = Physics2D.OverlapCircle(spawnPosition, radius);
        return overlap != null; // If there's a collider, the position is occupied
    }

Do you know where the variable sound of Ladder is?

[jolly urchin]

I don't

[willow scroll]

Got it. How do we consider the degree angle range of what's included in each direction?

[willow scroll]

This is your script, right?

[steep rose]

it is telling you to assign sound of ladder

[jolly urchin]

No, I was following a tutorial because I wanted to throw a simple walking sim thing together for friends

[steep rose]

you then must know where the variable sound of ladder is

[willow scroll]

Does this mean you cannot code at all?

[jolly urchin]

I do not

[jolly urchin]

Yes.

[steep rose]

show me your ladder script, please use one of the paste sites in the link

[wet bobcat]

I would like this to be a float, so 0.5 is forward-right, 0.75 is forward-right-right. Each scene has between 1-10 objects and they should have their own panning data. Does this make sense?

[jolly urchin]

I sent it

It's in the thing I sent

I put it on the paste site I usually use

[slender nymph]

that site appears to be absolute garbage for sending code. there's no line numbers or syntax highlighting

[steep rose]

ah I see, did you assign the sound variable in the inspector?

[jolly urchin]

I was trying to, but it... won't let me?

I figured that's what the problem was, but it doesn't allow me to alter it

[steep rose]

it is expecting an AudioSource

are you trying to give it an AudioSource?

[jolly urchin]

I've tried clicking and dragging both the audio file and the one assigned to the player, neither are accepted

[slender nymph]

audio files are not AudioSources. those are AudioClips

an AudioSource is the component that plays an AudioClip

[jolly urchin]

I have an audio source

It won't let me assign it to the script

[slender nymph]

what object is the AudioSource on

[jolly urchin]

LadderClimbSoundEffect is the audio source

I click it and drag to assign and it doesn't accept

[slender nymph]

do not assign it on the script asset, do it on the actual Ladder object in the scene

[jolly urchin]

Alright

Even though I've deleted that object though it won't compile

[slender nymph]

what compilation errors do you have

[jolly urchin]

Lemme try it again, one moment

[willow scroll]

Do we do this in 2D, neglecting the objects, which are on top of the camera?

[wet bobcat]

we do it in 2d, neither height or distance will be considered

[jolly urchin]

still just this one

[slender nymph]

this is a runtime exception, and has absolutely nothing to do with compilation. it tells you exactly what you need to do. you have an instance of the Ladder component in the scene where the sound variable has not been assigned

[jolly urchin]

How would I easily locate that instance? i've not been able to find it

[slender nymph]

you can use the search bar in the hierarchy, search t:Ladder to find all instances of the Ladder component

[jolly urchin]

Works now, thanks!

[nocturne kayak]

This is proving way too troublesome so i'm gonna be straighter here

Is there an easy way to replicate transform gizmo behavior without implementing the built-in gizmo system?

[sage peak]

Hey everyone! I dont know if this is anything to do with the code, but im facing an issue.
In my runner game for some reason after I added a road model and the obstacles, it doesnt let me jump as I want to, but if I keep pressing the arrow key it works eventually, maybe its the collider or something I dont know

Heres the script

using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    private CharacterController controller;
    private Vector3 direction;
    public float forwardSpeed;

    private int desiredLane = 1;
    public float laneDistance = 4;

    public float jumpForce;
    public float Gravity = -20;

    void Start()
    {
        controller = GetComponent<CharacterController>();
    }

    // Update is called once per frame
    void Update()
    {
        direction.z = forwardSpeed;

        if (controller.isGrounded)
        {
            // Reset vertical speed
            direction.y = 0;

            if (Input.GetKeyDown(KeyCode.UpArrow))
            {
                Jump();
            }
        }
        else
        {
            // Apply gravity when in the air
            direction.y += Gravity * Time.deltaTime;
        }

        // Lane switching logic
        if (Input.GetKeyDown(KeyCode.RightArrow))
        {
            desiredLane++;
            if (desiredLane == 3)
                desiredLane = 2;
        }

        if (Input.GetKeyDown(KeyCode.LeftArrow))
        {
            desiredLane--;
            if (desiredLane == -1)
                desiredLane = 0;
        }

        // Calculate target position based on lanes
        Vector3 targetPosition = transform.position.z * transform.forward + transform.position.y * transform.up;
        if (desiredLane == 0)
        {
            targetPosition += Vector3.left * laneDistance;
        }
        else if (desiredLane == 2)
        {
            targetPosition += Vector3.right * laneDistance;
        }

        // Smooth lane movement
        transform.position = Vector3.Lerp(transform.position, targetPosition, 80 * Time.fixedDeltaTime);
    }

    private void FixedUpdate()
    {
        controller.Move(direction * Time.fixedDeltaTime);
    }

    private void Jump()
    {
        direction.y = jumpForce;
    }
}```

[short hazel]

The last line of Update breaks the whole thing. You cannot directly assign to transform.position when using a CharacterController

[rich adder]

transform gizmos behavior ?

[wintry quarry]

An easier way than what?

[nocturne kayak]

than what i'm trying, i've been around for a few hours

hopefully this will get across what i'm trying to achieve, i managed to get a simple when mouse move cube move type of setup

but i'm trying to do that on the cube's local axis, and move along it when i drag one of those axis handles

[sage peak]

So then what do I do to fix it

[rich adder]

are you using Vector3.forward for example instead of transform.forward ?

[ruby python]

'ello again all. So, I've figured out the whole rotating a skybox using a custom skybox shader. I'm struggling a little with the Maths involved in getting the directional light that I'm using as my sun to rotate in sync with the skybox though.

Here's The Code

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

And here's the 'layout' of the Skybox Material. I figured grabbing the vectors and using those to control the sun direction would be the way to go, but the sun, while rotating, barely moves and I'm not really sure what kind of multiplier I should be using (I've tried a bunch of values in increments of 10 so far).

I will say that it's late and I'm very tired, so could be something ridiculously simple and obvious. Just want to get this bit done and then go to bed. lol.

[nocturne kayak]

Yup

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

[rich adder]

you probably want transform for local

[nocturne kayak]

this is the code in the cube right now

[ruby python]

Dangit, forgot the image. lol.

[rich adder]

also you're multiplying moveSensitivity twice

[nocturne kayak]

Ah, yeah, i just realized

sorry, my brain's fried at this point

[short hazel]

Do not use transform.position, use controller.Move() to adjust your lane position.

[nocturne kayak]

i just can't figure out what feels like the simplest of things

[lethal meadow]

if someone could help with this

#💻┃unity-talk message

I'd appreciate it

[nocturne kayak]

which is

when drag blue pill

cube move along blue pill axis

it feels so stupid

[rich adder]

oh transform.Translate is local so vector3 shouldbe local

[rich adder]

why is that

[nocturne kayak]

it feels like it should be simple

but apparently it isn't

[short hazel]

It's very much not simple to replicate this as close as Unity does it

[rocky canyon]

ya, i was gonna say.. to me it feels deceptively easy

[short hazel]

You'll need planes, raycasts, vector projections in order to adjust the object's local axis being moved to the mouse

[nocturne kayak]

i'm not trying to do the fullfeatureset of gizmos

[rocky canyon]

theres assets on the store that do this.. runtime transform gizmo or w/e but they pricey for what they are

[nocturne kayak]

just move it around , and rotate it in a single axis

[rocky canyon]

i think imma give it a try later on today

already have a pickup and carry script + top down isometric camera controller

sooo thats both pieces i need.. i could combine them probably and get something working.. i'll give u a ping if i do caecpr

[sage peak]

transform.controller.Move()????

Do I use it like this? If not then Im getting errors

[rich adder]

transform does not have such a property

[rocky canyon]

characterController.Move(finalVector * Time.deltaTime);

[nocturne kayak]

i had that in mind

i knew that'd take a lot of moving pieces, but still

i can get this working

[nocturne kayak]

and i can get this working

but the middle term is [??????]

[short hazel]

Not sure from where you'd even begin to implement it, but it would be something like below (taken from your image). This would "track" your mouse cursor perfectly from screen space to world space:

Red mouse position is the resulting world position of raycasting the plane

[nocturne kayak]

so, first things first

i gotta dynamically create a plane when an axis is clicked

[rocky canyon]

^ thats what i was trying to get out earlier

[nocturne kayak]

and then raycast to it?

[rocky canyon]

that diagram is 🔥

[nocturne kayak]

Agreed

thanks for the diagram btw

so if i have a plane and a line on that plane

i can just get the closest point on plane to line

[short hazel]

Yep, building the plane requires a point and a normal. That could be the center of your object (for the point), and for the normal a few if statements could solve it:
Clicked gizmo is Z => normal is transform.up
X => same
Y => any of transform.forward or transform.right

Then you feed your ray from Camera:ScreenPointToRay() into thePlane.Raycast() and get the position on the plane
And for projecting there's a few options available

[nocturne kayak]

oK

Let me try building it so far beforehand

feels like i'm calling it wrong, also that

that is what visual studio's telling me

[short hazel]

Plane is a type, so you need to make a variable and put a new instance of it into it

Plane p = new Plane(normal, point);

[rocky canyon]

lol he explained it sooo much better than i tried to

[bold saffron]

Ok, I understand this may be the most uneffective and badly written code EVER, but for some reason my game crashed when the roundtype is one and the "laser round" starts. I have no clue why.
https://pastebin.com/PFS5DDYR

[polar acorn]

How do you expect that while(true) loop to ever end

[bold saffron]

OH SHIT I FORGOT THE BREAK

😭

[keen dew]

There shouldn't be a while loop there at all

[bold saffron]

oh

wait

how

[polar acorn]

what is this loop supposed to be doing?

[bold saffron]

so that it can run even if roundtype changes

[polar acorn]

Well, you set all of those booleans to true, then start your loop that's going to run a number of times based on your framerate then always go into the complete3 condition since that one has the lowest timer

So, if roundType is 1, it's going to freeze for about a second then do that one always

[bold saffron]

oh

[polar acorn]

Loops run to completion

Until the loop is exited, literally nothing else can happen

So, every frame, you're going to loop that while loop until it runs the condition for complete3, then next frame it'll do it again

[bold saffron]

thank you! I rewrote the code so the while loop isn't needed

[dense pike]

Hii could I use some advice on my game

[deft grail]

you would need to say what advice you need

The goddamn plane probably needs to be centered on the object, not the screen space mouse position.

[gloomy marsh]

when i create action unity add using System; namespace and cant use Random.Range because UnityEngine.Random and System.Random have same class name Random. is there way to fix it

[nocturne kayak]

i forgot i named the variable that so when i read your notification i thought you were giving very agressive advice

[wintry quarry]

Two ways to fix this

Either type UnityEngine.Random.Range every time you use it

Or put this at the top:

using Random = UnityEngine.Random;```

[gloomy marsh]

really?

[wintry quarry]

Really

[gloomy marsh]

alright

thanks

[wintry quarry]

You understand why this is a problem right? The System namespace also has a class named Random

So it doesn't know if you want System.Random or UnityEngine.Random

The solutions I showed you above remove the ambiguity.

[gloomy marsh]

yeah yeah i already know the solution but it seems unprofessional

[steep rose]

whats not profesional about using system.random or unityengine.random?

[wintry quarry]

You could also do something like:

using UnityRandom = UnityEngine.Random;
using SystemRandom = System.Random;``` and then use ```cs
float result = UnityRandom.Range(a, b);
int anotherResult = new SystemRandom().Next();```

if you want to use them both for some reason

¯_(ツ)_/¯

[gloomy marsh]

i am professional beginner developer so that it

[steep rose]

beginner and professional should not be in the same sentence

[gloomy marsh]

i m kidding

[steep rose]

well still #💻┃code-beginner message

im not sure why you would need to rename and assign them differently

[vestal isle]

in unit test runner, how the heck do I reference a class in scripts folder?

Obviously using this suggestion won't work because the csproj is stupidly enough auto-generated.

[wintry quarry]

You need to put all your code that you want to test into an assembly

then you can have your test assembly reference the main code assembly

[vestal isle]

my lord

[wintry quarry]

To make assemblies in Unity you use Assembly Definition files

It's really not as scary as it sounds

Here's a good guide on how to set it up: https://www.kodeco.com/38240193-introduction-to-unity-unit-testing/page/2?page=1#toc-anchor-005

[vestal isle]

Thank you!

Gee, and now I get like 50 errors of missing references 🤔
I thought it'd be easy to set up, turns out it wasn't.

[wintry quarry]

1. The TMPRo ones are because you didn't reference the TextMeshPro package in your game assembly. Fix that by adding a reference to TextMeshPro

2. The Drawing one - not sure - it depends what this "Drawing" class is and where it lives. Most likely the fix is adding another reference, or moving that script into the assembly if it lives outside.

But even though there are "50" errors it looks like really it's only two

[vestal isle]

UnityEngine.Rendering doesn't even exist in the assembly definitions

[wintry quarry]

Are you using URP?

[vestal isle]

Not sure why it referenced that though .. So I can just delete it

I should be good, just needs refactoring

Okay, I'm good. I was just referencing pointless things.
Thank you 😛

[ivory jasper]

how can i have a repeating texture for the background of my camera?

[rich adder]

sprite renderer

[dusky sentinel]

hi! The facial expressions on the triangle represent the trust level between the characters. I want to update them when the trust level goes up. Right now im testing that by increasing the trust level of each relationship when I press numbers on the keypad.

The saddest face represents trust = 0 and the happiest face represents trust = 3. There are a total of 4 facial expressions. By default, all the faces are set to the saddest face and each face is named after a pair of characters(ex) annie-edward). However, when I press the number keypad, I see the trust levels increase but the facial expression sprites don't get updated. For instance, when I press one, the relationship at index=0 should increase in trust level and the face should be changing to a less sad one. I'm not sure why these changes in sprites aren't appearing when I press the keypad.

[ivory jasper]

how do it repeat infinitely

[rich adder]

there is an option on the texture to be tiled and set it repeating on sprite renderer

[ivory jasper]

oh okay

[nocturne kayak]

Is anyone here particularly knoweldgable on the MetaXR toolkit?

[crisp token]

ive got this basic playerRotationScript running on the root gameobject; https://hastebin.com/share/ujacizoqem.csharp

this is where im debugging from : https://hastebin.com/share/bajamubaki.csharp this script is also running on root object

[teal viper]

You are debugging many different things. Keep the transform.forward log only.

Or add more info to your logs, so that we can understand what variable it is.

[crisp token]

the other ones were just me trying to see if im dumb

ive done rotation before its the first thing most people do idk why this is giving me so much issue now

like the prefab rotates and the transform.forward should change idgi

[teal viper]

Well, I told earlier. .forward can't be 0,0,0 so I don't know what variable it is that we see in the log.

[crisp token]

oh

[teal viper]

Don't ever debug the values alone. It's a very bad practice.

[crisp token]

what should I debug instead?

[teal viper]

Something meaningful, so that we understand the context of the log

For example "transform forward: {value}"

[crisp token]

so transform.forward is actually stuck at (0,0,1) (my b)

[teal viper]

Great, that's progress.

My guess is that the transform that you debug doesn't belong to the object that you rotate in the scene.

Debug the name of the object

[crisp token]

hmm, I thought the transform keyword automatically would, but let me use GetComponent to make sure and debug the object

[teal viper]

No need to use GetComponent. It would result in the same thing.

[crisp token]

object seems to be correct

[teal viper]

You can also pass the object itself as the second parameter of the Log. That would allow you to click the log message to select the object in the hierarchy.

[crisp token]

doing that now

[crisp token]

yeah its the root object, as expected (i opened the hierarchy and clicked to confirm)

this is strange

[teal viper]

Okay. And the one you're rotating is the root object as well?

[crisp token]

yeah the PlayerRotation is running directly on the root

and in the inspector its y rotation is changing

maybe since its rotation is always (0, x, 0) . transform.forward will actually always return the same thing? (idts)

cause the blue arrow in the scene is changing

[teal viper]

I see that there's networking involved. I wonder if it is related.

[crisp token]

yeah but rn the networking stuff isnt doing anything, it could be some of the overhead

like Network Object for ex

[teal viper]

How are you rotating the object?

[crisp token]

i was tersting different methods of setting rotation to see if that would fix it

[teal viper]

Log the transform.forward tight after rotating it.

[crisp token]

you're on to something

its updating properly

[teal viper]

So, it's something resetting the property afterwards.

[crisp token]

is it a read only variable, could i be resetting it"?

well i cant set .forw but ig i can reset rotation

ill look into it, i might have a bigger issue here. Thanks for your help

[teal viper]

It's not. You can set it.

[crisp token]

you can set transform.forward?

[teal viper]

Yes

[crisp token]

oh, ill look out for that then. Im going through my whole tick cycle rn

[teal viper]

That would rotate the object such that it faces the direction.

[crisp token]

@teal viper I fixed the error by swapping the exectution order of PlayerRotation and some other script. The playerrotation was applying the rotation after the Transform.forward. I am still a little confused, however, because I do not think that transform.forward would be resetting on its own. There may still be another error with my code

[teal viper]

Transform forward represents the forward direction of the object, which depends on the object rotation. So when you rotate the object, it's forward changes. Same is true the other way around. When you change the forward dir, unity rotates the object.

[crisp token]

I see, not trying to be rude but I dont understand your point

[teal viper]

I was trying to clarify your confusion.

Ah, maybe I misread.

[topaz mortar]

I'm making a 3d tower defense game, currently adding exploding missiles that need to hit multiple enemies when they explode.
I saw a Brackeys tutorial where he uses Physics.OverlapSphere to get all colliders within range.
On the docs of Physics.OverlapSphere is says consider using: Physics.OverlapSphereNonAlloc, when should I use which? Is this a good way to make exploding missiles in a TD?

[teal viper]

Transform forward does not reset on it's own. It must be either your code or potentially other components(like the networking related stuff).@crisp token

[crisp token]

ugh i hate not knowing why a fix works but it works perfectly lmao.

if there was some reset, its not like this would fix it anyway

im wondering if it has to do with the fact that there is a rigidbody on the object and I manually call the physics simulation

[teal viper]

Well, think. You changed the order of execution and it fixed it. That would imply that something in the script that was executing earlier before was modifying/resetting the rotation(or forward/right/up) of the object.

[teal viper]

Very much possible. Assuming you sync the rb to the transform in update.

[crisp token]

Just tested it by reversing the order of execution and using Rigidbody.Rotation (which apparently is proper way) and it works fine. So yeah, that was the issue, glad we figured it out

thank you again @teal viper

[crisp hamlet]

https://discussions.unity.com/t/explosion-raycast/706738
Try this maybe

[topaz mortar]

ah raycasts again 🙂 definitely an option

[eternal needle]

Physics.OverlapSphereNonAlloc is always better, it doesnt allocate.

though similar to the discussion yesterday, raycasts alone dont work here either

the post they linked you doesnt even have a solution.. its just someone saying it doesnt work and there not being a real answer

they don't?

Physics.OverlapSphereNonAlloc does seem a lot simpler

[eternal needle]

a raycast gets you information in a straight line, you arent gonna reasonably use it to get you everything in a sphere. the only use for raycast here would be checking line of sight

[topaz mortar]

but you can just fire raycasts all around not?

[keen dew]

Do you have a reason to check the line of sight? For example are there obstacles that would prevent explosion damage even if the target is inside the blast radius?

[topaz mortar]

it's an option, but I don't think it's necessary, I don't mind my explosions going through the walls

[keen dew]

Then I don't see why you wouldn't use OverlapSphere as it's literally one line and the simplest way to do it

[elfin hatch]

I'm currently trying to make a hinge-joint onto a gameobject that needs a non-kinematic rigidbody, but was concave....
So I cut the object into 6 convex pieces as child objects, each with their own piece of meshrenderer/meshcollider, and connected them together with fixed-joints.

I'm having issues though using that parent gameobject to hinge-joint onto something... the item just starts floating away.
Is this a problem because the colliders aren't on this object, and are instead child-objects? or how do i solve this

nvm just ignored the parent, and did it on the 1 child thats closest.
this whole joint stuff is still "wobbly" though... time to tinker

[topaz mortar]

the amount of code doesn't matter, it's about optimizing performance

[keen dew]

I don't see how firing dozens of raycasts and pruning the hits for duplicates could be faster than one overlapsphere

[teal viper]

Premature optimizations: make it more code and less performant

[topaz mortar]

I have no idea about the performance of physics, but you're probably right

[eternal needle]

i wasnt even really referring to the performance. raycasts and overlap spheres solve entirely different problems.
raycasts cant solve the problem of finding every object in a sphere.
First issue is raycasts in 3d by default dont hit the object they start inside of. Theres workarounds to this but its not the main point
2nd issue is just math. As the sphere grows larger, you arent gonna add more raycasts to cover the range of the sphere. Refer to the image i made. Even if you say you can add more raycasts to check, i could always just make the sphere larger in the example and draw a box between the raycasts near the edge of the sphere. Even if this is an extreme case, it still shows cases where raycasts will fail

[fluid lagoon]

i cant name my parameters please help it ruind all my code and i am really stuck please help me

[slender nymph]

don't crosspost. this is not a code issue. have you tried restarting the editor

[fluid lagoon]

so where should i post this and do you mean restarting unity?

[slender nymph]

you've already asked the question in the correct place #💻┃unity-talk
this is why you shouldn't post questions all across the server. and yes, typically when people refer to "the editor" they mean the Unity Editor, which is the application you use to actually edit your project

[topaz mortar]

what would I use to draw lines across my grid in 3d to show the path monsters will take
I want to draw this in code since the path is dynamic

[slender nymph]

just for debugging purposes? because you can use Gizmos for that

[topaz mortar]

no to show in the actual game

been searching for it for a bit, but can't find exactly what I need

[teal viper]

Line renderer

[slender nymph]

LineRenderer or you can draw the lines manually with GL.LINES

[topaz mortar]

so I add a linerenderer component on my current grid node?

[slender nymph]

what you attach the linerenderer(s) to entirely depends on your setup so we can't really answer that 🤷‍♂️

[teal viper]

Presumably it's a game wide mechanic, so you probably should implement it as a singleton or a manager. Basically, one GameObject that draws all your desired lines.

At least that's what I'd do probably.

[topaz mortar]

cool thx, seems to work, now just need to finetune a bit (or a lot)

[tulip nimbus]

ok why wont this work? Should i use OnColliderStay?

[slender nymph]

GetKeyDown is only true for the first frame that the key is pressed and OnTriggerStay (as well as all of the physics messages) is only ever called on FixedUpdate frames so you are likely just missing the input

[topaz mortar]

Which part is not working? If you don't see OnEnemy in the console then you have an issue with your trigger, not sure what that even is OnTriggerStay?

[tulip nimbus]

i believe it triggers as long as you come into contact with the other game object

[topaz mortar]

yeah seems right, so do you see the OnEnemy text? there's several potential issues if you don't

[tulip nimbus]

nah i dont see anything, not a single message unfortunately

the tags are assigned

ill try to figure something out with what boxfriend said and ill see

[topaz mortar]

show us your objects in the Inspector

boxfriend's message only applies if you see the OnEnemy in console

[slender nymph]

if you are not seeing the OnEnemy log then go through this: https://unity.huh.how/physics-messages

[tulip nimbus]

This is the enemy that the player is supposed to collide with as a trigger

i might have to check Is trigger one sec

[keen dew]

no collider

[tulip nimbus]

i just added one, compleately my bad, but it still wont work ):

[keen dew]

Go through the steps in that link, one by one

[tulip nimbus]

👍

[topaz mortar]

Gonna bookmark this too 🙂

[tulip nimbus]

ill go trough the site thank you all for your time

[topaz mortar]

Unity should hire boxfriend as a Discord helper 🙂

[slender nymph]

lol as much as getting paid for this sounds nice, i definitely don't want to be required to help people lmao

[silk night]

can confirm, went from moderating a big discord voluntarily to getting paid to do it part time, leeched all the fun out of it 😄

[brittle pond]

I'm not sure if this is a beginner question. But i'm having trouble with referencing a script. I've never used any type of help from chatting before so bare with me.

[teal viper]

Maybe explain better what you're trying to do and what the script is depicting?

[brittle pond]

Okay. So i created a gameobject that has an exp bar (ui) which has a script attached to it to update the current xp value which changes the fill amount of the exp bar. Now i cloned that exp bar (because i need the player to be able to instantiate multiple exp bars) the issue is just, when i update the amount of exp (by the press of a button) it only updates the value on the original exp bar and not the one cloned one

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

I hope that kind of captures what i'm trying to do

i'm not the best at coding but i'm trying to learn

trying to reference to this

[languid spire]

public class progresbar : MonoBehaviour
C# is case sensitive

[brittle pond]

Thank you

[willow scroll]

Represent the object's position relatively to the camera's direction

[willow scroll]

The classes in C# are called with PascalCase, so YourMethodIsSupposedToLookLikeThis.
Also this.gameObject can be removed, since the GameObject.GetComponent method can be used without the GameObject reference because of your MonoBehaviour already deriving from it

Do you not see the bot message above?

[topaz mortar]

Is it bad to first do transform.Translate(newPosition) and then after that clamp the x, y, z values and set transform.position = clampedPosition?
Or would it be better to just set the transform.position to the clamped values? Not sure if .Translate does anything special

Why would you even use transform.Translate? why not just transform.position = newposition?

There will be a save button usually at the top right or left. The URL should have changed now. Copy the changed URL and paste it here.

[teal viper]

Because they do different things.

Translate moves the object by the movement vector that you pass into it. Setting position sets the object position to the specified position.

[topaz mortar]

{
    if (relativeTo == Space.World)
    {
        position += translation;
    }
    else
    {
        position += TransformDirection(translation);
    }
}```
Seems pretty similar?
So it's just transform.position += amountToMove then? Not sure why there's a function for this? Am I missing something?

[teal viper]

Yes, it is.

+= is not the same as =

[topaz mortar]

why is there a function for that? why don't ppl just += instead?

[teal viper]

There are many functions that don't have much use.🤷‍♂️

[topaz mortar]

cool thx 🙂

[teal viper]

Also, if you note, it can be convenient if used to move in local space.

[ivory bobcat]

The difficulty would be subjective to the individual. A person could also potentially argue against CC and RB suggesting Physics casts and manually implementing gravity etc

[topaz mortar]

so back to my original question
is it ok to set the position, clamp it and then set it again?
or would it be (noticably) better to only set the position once? so calculate the new position first, clamp it and then just set it once

[teal viper]

There's isn't much difference imho.

[ivory bobcat]

Doubtful that it would make much of a difference but you ought to determine the final output before actually applying it to the Transform if possible.

[burnt vapor]

Negligible difference, don't worry about "optimizing" stuff like this because you're unlikely to improve anything

We're talking about a mere nanosecond difference here for setting a value

[ivory bobcat]

Unless you've got physics sync with the Transform enabled or something.

[topaz mortar]

yeah mostly asking so I get a better understanding of how things work 🙂

[languid spire]

noticable, probably not, totally illogical, most definitely

If you stumble upon needing to improve your performance this would be one of the last things you improve on

[burnt vapor]

What is your issue? I have no idea what you are talking about

[topaz mortar]

well I'm just prototyping atm, but still better to learn things the right way not?

[burnt vapor]

Also, six files of code is not something anybody is going to debug

[burnt vapor]

Sure, but one person would say to avoid code duplication or excessive calls, and the other would tell you to keep it simple

I tell you to keep it simple and worry about optimization later.

[teal viper]

You just need to avoid setting the rotation in your FirstPerLook, when a menu is open.

[ivory bobcat]

Probably not as well. Just plan the basics, implement what you can with your current skills and research the necessary. If you're just experimenting to learn then trying to find the absolute best way to do something could be a rabbit hole worth investigating.

        newPosition.y = Mathf.Clamp(newPosition.y, 3, 15);
        newPosition.x = Mathf.Clamp(newPosition.x, 1, 18);
        newPosition.z = Mathf.Clamp(newPosition.z, -2, 7);

        transform.position = newPosition;
    }```
simple enough not? sure it took a few minutes, mostly just asking here, but at least now I understand what is happening 🙂

[burnt vapor]

I would split the logic that checks the keys from the logic that actually updates the position.

Like, you currently have a bunch of if statements that are long because you check for input

I'd put that separately

[topaz mortar]

what happened to keeping it simple? 😦

[burnt vapor]

Either by having the method return what to add to newPosition, or even by returning the Vector3/direction as an enum

[burnt vapor]

How is it not simple?

[teal viper]

Readability is part of "simpler"

[burnt vapor]

Sure, putting it all in your update method is simple, but this turns unreadable quick

[willow scroll]

What happened to keeping it readable?

[topaz mortar]

well I don't know how to do it so lol

[burnt vapor]

Considering there are two different logical steps in the code, you could separate the two

[willow scroll]

You should create a Vector2 out of the keys and apply the movement once

[topaz mortar]

this structure makes a lot of sense to me, not sure why it's not good

[burnt vapor]

I already explained

[willow scroll]

Because it looks bad

[burnt vapor]

This

Or an enum

[ivory bobcat]

I'd is the individuals personal take on it.
If it works, it works.. but others can still criticize it.

[burnt vapor]

Regardless, it should be clear that keys return a direction

[willow scroll]

You may create a list, which contains the keys

Well, it would be a readonly Dictionary<enum, List<KeyCode>>

[topaz mortar]

not sure if you're trolling me or not lol

[willow scroll]

Why would I?

Although, in your case, there is an additional condition, so Func<bool> is required

But, honestly, using the new input system is the best variant here

[burnt vapor]

I don't think I would put in a dictionary myself

The if-statements are long and complex

[topaz mortar]

lol I literally have no idea what you're talking about so I'm just gonna leave it like this

[willow scroll]

Well, do you know what a dictionary is in C#?

[topaz mortar]

yes

[burnt vapor]

I would just separate it from the newPosition and into a new method that returns the Vector3 direction

[topaz mortar]

yeah that part I get

[burnt vapor]

So what's the issue?

You asked for improvements, I'm not sure how else I could explain

[topaz mortar]

I think it's overcomplicated and makes it less readable tbh

[burnt vapor]

Then I see no point in discussing it

[topaz mortar]

agree 🙂

[burnt vapor]

You'll see why this matters once your project grows, probably

I didn't understand how to keep things simple until I made a massive project

[willow scroll]

Yeah, just keep your code filthy 🙂

[burnt vapor]

This mostly only matters if your script grows into different parts which makes it unclear when the next thing happens. In your case it's two parts, which is still readable to an extend

[steep rose]

A ton of if statements is not preferable either way

[topaz mortar]

how else would I detect which key is pressed?

[night valve]

Dictionary :p

[steep rose]

Do exactly what sashok said lmao

[topaz mortar]

lol

at least now I know what sashok was saying 🤣

[burnt vapor]

A dictionary will just be unreadable in this case

Getting rid of the if-statements only make sense if they are not this complex

Alternatively use a switch statement

[burnt vapor]

To comment on this, this is part of a map editor I am writing https://gdl.space/zisanutefu.cs

This is the splitting I am talking about

Two different groups of input, and then other logic

[topaz mortar]

probably wrong channel, but since we're on the topic, is it me or is my line moving as I zoom in & out?

must be lagging from the complex if statements

[burnt vapor]

You got your priorities wrong if you still think a few if statements are going to lag your game

Especially the ones you shared

I don't see lag, I just see a camera that isn't smooth

[willow scroll]

This is how I would implement it. Make sure the names are changed, since they are bad.

private readonly Dictionary<Vector2, (List<KeyCode> keys, Func<bool> condition)> 
    _directionKeys = new() { ... };

private Vector2 GetDirection()
{
    Vector2 direction = default;

    for (int i = 0; i < _directionKeys.Count; i++)
    {
        var directionKey = _directionKeys[i];
        var directionValue = _directionKeys[i].value;
      
        if (directionValue.keys.Any(k => Input.GetKey(k)) || directionValue.condition)
        {
            direction += directionKey.key;
            
            if (i % 2 == 0)
                i++;
        }
    }
    return direction;
}

[topaz mortar]

I'm joking 😉

[topaz mortar]

any tips on that? or should I google unity smooth camera?

[topaz mortar]

try to narrow down your problem
tell us what you tried and what exactly is not working
you should at least be able to identify in which part of your code it's going wrong

[willow scroll]

You have to lerp it with a coroutine

The line looks like it's moving because of how rough the camera movement is

[topaz mortar]

ok so this definitely does not do what I want it to do:
transform.position = Vector3.SmoothDamp(transform.position, newPosition, ref velocity, 0.1f);.

camera movement becomes extremely slow and zooming is jittery

[burnt vapor]

Camera uses an actual position. Add a "target position" that the camera constantly lerps to based on its current position. When you update the camera, instead update the target position and have the camera move itself.

[topaz mortar]

and if I lower the 0.1f it's back to rough movement

[summer hound]

If i have, say a Cube, with a NavMeshAgent and a Rigidbody and SphereCollider, and i want the cube to move to a specific point, and "jump up on a chair", to sit on the chair, im using a "sittingPoint2 on the chair. But, when my cube comes to the chair and i call the change for my "sittingPoints" transform, the cube ain't lifting from the ground. How come?

private void RotateTowards(Transform workPoint)
{
    Rigidbody rb = GetComponent<Rigidbody>();

    if (rb != null)
    {
        Vector3 newPosition = new Vector3(workPoint.position.x, transform.position.y, workPoint.position.z);
        rb.MovePosition(newPosition);
    }

}

[burnt vapor]

First of all, check if rb.MovePosition is called at all

Is it? You can use logging for example

Secondly, log the value of workPoint.position.z when rb.MovePosition is called and verify it changes

[summer hound]

Ooooh, so i have to make the change in the rb.MovePosition... Got it, ill try!

I mean, having it called 🙂

[ivory bobcat]

        if (rb != null)
        {
            Debug.Log($"Position Before: {transform.position}");
            Vector3 newPosition = new Vector3(workPoint.position.x, transform.position.y, workPoint.position.z);
            Debug.Log($"Position Expected: {newPosition}");
            rb.MovePosition(newPosition);
            Debug.Log($"Position After: {transform.position}");
        }```

[topaz mortar]

oh cool, that looks nice!!
line still moves though

[wanton canyon]

Hello, trying to find a tutorial on how to program a creature that is swimming in the water but everything coming up is about the player swimming. Can someone point me in the right direction for how to have, say, a shark patrol the waters?

[hexed terrace]

what you want to do is look for two separate tutorials.
1- swimming -> the player swimming tutorials will give you the swimming bit.
2- "shark" patrol -> find tutorials about general AI/ NPC patrolling

You are unlikely to find a tutorial about swimming sharks patrolling

[wanton canyon]

Yeah it doesn't have to be that specific, Im just confused on how to make the model "float" in the water while patrolling

[burnt vapor]

Don't see anything from a simple video

Perhaps it's just adjusting based on how close the camera is, idk

[topaz mortar]

I think it's a camera issue, it's breaking my hexes as well

I know there's a pixel perfect camera for 2d projects, but that won't work for 3d will it?

[steep rose]

turn on anti ailiasing for the hex breakup

whatever type is totally up to you

[topaz mortar]

I think I'll just switch to an orthographic camera, makes more sense for my game anyway

I tried SMAA but didn't help

[steep rose]

try TAA if unity has it

Disabling TAA because MSAA is on.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

spammed in console

[steep rose]

but anti ailiasing only does so much, it entirely depends on how many pixels you have on your monitor

[steep rose]

look at logs in the unity folder

i dont know what would be causing that

[topaz mortar]

ah there's another dropdown in the camera settings to turn off MSAA
TAA fixes my hex graphics, but my entire game is flickery now

[steep rose]

show me what you mean

[topaz mortar]

not sure if u can see it, the line makes it a bit more obvious

ah yeah it shows pretty clearly

ok, so I made my camera Size scrollable and now the jitter on the tiles is gone somehow 🤯
the red line is still flickering though

ok it seems to be only at certain camera positions, not everywhere

[steep rose]

if that solution works, i believe you are good

you can turn the quality setting up more or try FXAA (if needed)

[timid ember]

whats the error here?

In VSC, the error is shown as a red underline on ContextMenu

im currently learning enums

[cosmic dagger]

the error is pretty clear, no?

[timid ember]

please tell me

[cosmic dagger]

did you read the error message?

[timid ember]

yes but i cant understand it

[timid ember]

what does it mean by method delcaration

[cosmic dagger]

it is only valid on methods. did you place it on a method?

okay, do you know what a method is?

[timid ember]

no

[cosmic dagger]

well, that's a problem as it's a basic concept and very important . . .

you have a method in the image you posted. not sure how you don't know that . . .

[timid ember]

oh

public class isnt a method?

[cosmic dagger]

public class <InsertClassName> is a class, not a method . . .

i recommend following a beginner C# tutorial to learn the basics. these are concepts you really have to understand . . .

[timid ember]

does this hav anything to do with it?

[cosmic dagger]

no. you placed [ContextMenu] above a type declaration—which is not allowed, hence, the error. i posted what and where the type declaration is. the error states it is only valid for method declarations (which i also posted what and where that is) . . .

[timid ember]

what should be the correction then?

I am using contextmenu to show my enums

wait

[cosmic dagger]

[ContextMenu] is used to add a menu item in the inspector. you place it on methods to call them from the inspector . . .

[timid ember]

why does this work

[cosmic dagger]

• remove it from the type declaration because it cannot go there
• move it to the method declaration because it goes there . . .

[cosmic dagger]

by default, your enums will display from the inspector . . .

    }
}

[cosmic dagger]

those 3 marks at the beginning are backticks . . .

[timid ember]

ok

why does this work

[cosmic dagger]

specifically, which part? where do you expect an error?

[timid ember]

contextmenu

i am gonna watch a tut

[cosmic dagger]

uhh, i'm not sure how else to explain it. as the error states, [ContextMenu] is only valid on method declarations. in this snippet, you correctly have it placed on top of a method declaration. That is why it works . . .

[cobalt sentinel]

Hello, have this code, And when the enemy gets hit, he sometimes get hit and sometimes he dont, does someone know why?

[rich adder]

depends how you move the sword

also [SerializeField] is to expose private variables, public are already exposed

hence the 3 dots telling you so

[cobalt sentinel]

it says comparing tags with == is inefficient

what can i do?

[cobalt sentinel]

oh, okay

[rich adder]

use CompareTag. I also was specifically talking about the 3 dots on the serializefield attribute.
anyway show how you move the sword / enemy

[cosmic dagger]

earlier, a provided an image to show where the [method](#💻┃code-beginner message) declaration is . . .

[timid ember]

serialize field is a method?

[cosmic dagger]

no, that is an attribute . . .

[cobalt sentinel]

The sword (the yellow thing is the radius of the attack but its the same) is that, and when i click it activates and then disactivates

and the red thing is the enemy

@rich adder

[rich adder]

so it doesnt move?

also Idk if OnTriggerEnter gets called when collider is already inside does it ?

[cosmic dagger]

@timid ember a method is a block of code containing a group of statements. they can only be defined in a type . . .

[cobalt sentinel]

idk let me see

[cosmic dagger]

the object must exit the collider and re-enter to trigger the collision again . . .

[cobalt sentinel]

so, if i stay still, it dont gets hit, but if i move it gets hit

[cobalt sentinel]

how can i do that?

[rich adder]

just use an overlap if you need to activate a hurt

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircle.html

[cosmic dagger]

if an attack was executed and the sword is still inside the collider, you can register that as a hit. you'd have to create the logic for this, though, it's much easier to use an OverlapXXX or CheckXXX method instead . . .

[cobalt sentinel]

wait

i did something more simple

i enabled and disabled the box collider

and it works

Thanks!

@steep rose after a lil searching and understanding stuff I think I choose cc and also the learn.unity Which one. Should I choose

alrighty did you follow the course i provided? just remember a CC is hard to implement for beginners so it might take some time

also wdym which one should you choose?

Hi all,

Would anyone be able to take a quick look at my code and see if they can see where I'm going wrong and what is causing my wheels to do this please? Been staring at it a while and it' baffling the crap out me 😕

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

[steep rose]

try using local position

and local rotation

wait wait wait, why not just make them a child of the wheel colliders in scene view?

[ruby python]

I did, and it did the same thing. 😕

Really weird thing though is that it's putting the 'root' object (empty) of the wheels, which are the objects that I'm referencing in the code, in the correct positions/rotations, but it's offsetting the actual visual mesh (which is a child of the root object), which I don't reference anywhere.

And making them a child doesn't work because the collider moves independently of the GameObject it's attached to.

Just tried assigning the wheel meshed directly and that works fine. Something a bit screwy going on when the meshes are children of something else. 😕

[hallow acorn]

why does it give me a NullReferenceException? if (playerControls.Interacting.Interact.WasPressedThisFrame())

Log and see which variable is throwing the nre

[nocturne kayak]

Quick question

How would i go about moving a parent through a child?

[rich adder]

reference the parent?

[cosmic dagger]

through? in what sense?

[rich adder]

@nocturne kayak if you mean how parent moves the child transform , you can't

[lofty sequoia]

I'm doing a sprite swap Toggle (UI Element) and modifying the isOn on one of the Toggles, but the sprite swap doesn't change to display the right image unless I click on it

[nocturne kayak]

using a child to move a parent

some people that have been putting up with my BS might have read what i'm trying to do, but basically, i want to use the blue and red axis as transform handles

[cosmic dagger]

by default, the parent moves the child. if you want the child to move the parent, then move the parent instead . . .

[rich adder]

move them through physics and you can push anything

just make sure child has bigger mass when you do
ohh you're not trying to make them collide? this is a grab tool ?
You need to script it then.

[cyan token]

damn bro you a baddie fr

[nocturne kayak]

That's more or less what i meant to say, sorry, i'm getting kinda tunnel visioned, but there's a long way to go in this project and i need it done by january, so thought process isn't really it's best right now

[nocturne kayak]

thanks boo

[eternal needle]

Instead of moving the child, just move the parent

Oops someone else said that

[nocturne kayak]

Problem with that approach is

the movement constraint is tied to the handle

So how would i go about moving a parent based on a child's movement constraint?

Is the best way to just take how much the child has moved, subtract that movement to the child and apply it to the parent? or is there a better way?

[eternal needle]

The better way is just directly moving the parent. Im not sure what movement constraint you're talking about but I dont see why you cant just replace the reference for what's being moved in the code on the child object

[lofty sequoia]

I think I may just end up implementing my own toggle system as Unity's doesn't work

[rich adder]

wdym it works just fine

[nocturne kayak]

right now i'm using meta's XR sdk

So i achieved that movement through meta's components alone

[rich adder]

just reference the parent transform and move that lol

[lofty sequoia]

setting the isOn on the toggle via script does not update the Toggle's sprite when using a sprite swap. It only changes when pressing it (must be in the onpointer down that changes the graphic)

[rich adder]

are you talking about the Ui.Toggle or the UIElements.Toggle

[lofty sequoia]

UI.Toggle

[rich adder]

ohh so you mean the checkmark doesn't come up when you do change value via code?

[lofty sequoia]

not the checkmark, but the sprite transition doesn't occur

[rich adder]

ohh those like the "hovering"

those are coming from EventSystem

[lofty sequoia]

ah and it looks like the eventsystem interacts with Selectable. Using Select() on the toggle does what I want

[rich adder]

oh nicee.yup was gonna send the docs link but wanted to link the new one

[kindred marsh]

When called through CollideMeleeHitbox() CheckCollisions() gives "Object reference is not set to an instance of an object" because the collisionManagement is null, even though it is defined in Start(). CheckCollisions() works perfectly in other situations. Summon melee hitbox is called through a timer that takes in an int and an Action as arguments.

[eternal needle]

!code and you should show the error since itll include the line number. If its telling you something is null, then it is.

You can directly assign the velocity from the transform.forward of the player. You can also set the transform.forward of the bullet to be that same vector or create a rotation with LookRotation

move is basically being called in FixedUpdate every frame when I'm pressing the button

[steep rose]

are you pressing the button the unpressing it?

[frank flare]

no, while that strange effect happens the button is pressed

[eternal needle]

That is a massive overuse of regions..
Also your debug doesnt show anything for collisionManagement. Debug collisionManagement == null

[kindred marsh]

It does show in the lower log which is sent by line 37

[steep rose]

show me where move and rotate are in your code

[kindred marsh]

But not in the top one which is sent by line 43

[frank flare]

@steep rose here

[steep rose]

i dont see move or rotate being called

show me where it is being called

[kindred marsh]

Regions let me collapse code and makes everything easier to read and work with

[frank flare]

they're called from event

[eternal needle]

You can already collapse methods. And yes you say it shows in the log which happens after the error. Before the error its clearly null. Im not really sure what the confusion is. Its null, the console isnt lying to you.

[kindred marsh]

Yes but they dont stay collapsed when you reopen a file

Ohh right

So for some reason CheckCollisions() is called before Start()?

Even though the hitbox is Instantiated before the collisions are checked

[steep rose]

try debugging your input to see if it deactivates or not

sorry for the late response I was building a flight stick

[rich adder]

lmao you still kept the example names I gave you ?

[frank flare]

yes

[frank flare]

what do you mean deactivaatees

I think it's problem with that force thing

[steep rose]

if the input stops or not

[rich adder]

did you debug other movement
pretty sure this looks wrong
-transform.up is probably changing as you rotate

since its the local direction according to the transform

[frank flare]

yeah Vector3 way seems to be working better

public void move(float speed)
{
otherPlayer_rb.AddRelativeForce(Vector3.forward * speed * 600f);
}

public void rotate(float speed)
{
    otherPlayer_rb.AddRelativeTorque(-Vector3.up * speed * 600f);
}

[steep rose]

actually you are suppose to do that since you are already using local space

i totally forgot about that

and i even looked at documentation

[frank flare]

how can I make the cube rotation not accelerate?

[willow scroll]

I got a headache from watching this.

You have to use the Rigidbody.MoveRotatation method, which smoothly changes the direction, checking for any Colliders on the way

[wintry quarry]

1. Only apply the force once
2. Set the angular velocity directly
3. rotate it manually

[frank flare]

it doesn't have noclip problems, right?

[willow scroll]

"noclip problems"?

[wintry quarry]

MoveRotation does not respect collisions

[frank flare]

yeah, when you rotate on a high speed and it noclips

[wintry quarry]

Set the angularVelocity - or only add a force once

[willow scroll]

It does respect collisions.

[willow scroll]

Not sure what "noclips" mean

[frank flare]

noclip means some object is going through the other object

[willow scroll]

No, MoveRotation checks for collisions

If required, use transform.rotation to teleport the Rigidbody

[night raptor]

mmh, not really. Only for kinematic rigidbodies it does have any difference compared to simply modifying the rotation

[rich adder]

isn't MoveRotation like Moveposition, it makes other RBs respect its physics movement but itself doesn't collide with anything properly like AddTorque ?

[night raptor]

That's what I thought, only when it's kinematic though

[rich adder]

Moveposition doc says its mainly for Kinematics, but doesn't mention anything on MoveRotation page , the name makes me assume its similiar? not sure 😅

[autumn pine]

how can I disable a main class script and all subclass scripts in one call

all on same object

[rich adder]

a loop probably

[eternal needle]

Call GetComponents<BaseClass> then just disable them all

[wintry quarry]

Why would a single object have a "main class" and "subclass" scripts on it?

That seems like a weird setup

wouldn't it only have one?

[night raptor]

I'd assume it is the same. If I had to guess, .velocity and .angularVelocity fields could be used to indicate the movement of the object only if it was kinematic

Haven't tried whether they change when calling MovePosition/Rotation though

[kindred marsh]

Yeah this seems to be the problem, but why does it happen?

[rich adder]

from my understanding the 3D engine kinematics don't have either one of those velocities, so I assume those are why those methods are the alternative to velocity

[night raptor]

What I meant is that those fields could be used to hold the velocity of a kinematic body when calling a Move... method since they are not used otherwise

[rich adder]

OH I see yeah , I assume they are not overwritten in the next physics frame right?

[frank flare]

what's the purpose of fixed update fixed delta time? isn't fixed update already fixed by itself?

[rich adder]

https://docs.unity3d.com/Manual/TimeFrameManagement.html

[autumn pine]

I can't figure out how to address all subclasses just by the main class

like calling a method on a subclass just by doing main.method()

instead ends up with a missed reference

[kindred marsh]

Ok fixed my problem by moving everything from Start() to Awake() in the script

[frank flare]

the MoveRotation way works but can I make acceleration and deacceleration there?

public void move(float speed)
{
otherPlayer_rb.AddRelativeForce(Vector3.forward * speed * 100f);
}

public void rotate(float speed)
{
    // otherPlayer_rb.AddRelativeTorque(-Vector3.up * speed * 100f);
    Quaternion deltaRotation = Quaternion.Euler(new Vector3(0, -speed * 10f, 0) * Time.fixedDeltaTime);
    Debug.Log($"Adding rotation to an object: {deltaRotation}");
    otherPlayer_rb.MoveRotation(otherPlayer_rb.rotation * deltaRotation);
}

[rich adder]

if you want acceleration use the AddTorque then clamp the AngularVelocity / stop adding torque if threshold reach, depending on behavior you want.

MoveRotation will not care about mass or any of that acceleration, you would need to write your own (could potentially just use a animation curve / lerp)

[night raptor]

Just tried with a simple test script just to make sure my assumption was correct and indeed both .velocity and .eulerAngles do change when MovePosition and MoveRotation was called and only happens when the body is set to kinematic. Non-kinematic body just gets teleported and doesn't behave well at all with other bodies when moved or rotated with Move... methods (just tried and confirmed it happens with the rotation as well). Interestingly enough if I call the Move... methods only for a one frame (for a kinematic body), the velocity fields will not change immediately but can only be detected the next FixedUpdate and then the next FixedUpdate they will reset to all zeros

[rich adder]

Ahh that's very good to know, I have only used those methods when its kinematic, yeah dynamic were giving me other issues (and the whole not stopped by other dynamic bodies/colliders)

I wonder if its the same on Box2D.. iirc that has velocity for kinematic? that always throws me off lol

[night raptor]

As far as I know, the 2D engine works pretty much the opposite and non kinematic bodies actually do work well together with the Move... methods. Don't know how it works with kinematic ones but the way I understand it, calling Move... on a non kinematic one will just change the velocity fields so the given position will be reached during the next physics step (assuming nothing is blocking the object)

[rich adder]

Interesting, I'm gonna test some stuff out. Very informative btw , thanks

[night raptor]

np, bit confusing how the 2D and 3D engines work differently but I guess it's just a consequence of Unity using third party physics solutions which are not meant to have the same functionality

[frank flare]

there's angularVelocity for AddRelativeTorue but is there a similar property for AddRelativeForce?

[frank flare]

nvm I found it

[rich adder]

literally velocity lol

it was renamed in 6 though to linearVelocity

[wintry quarry]

what do you mean by "missed reference"?

And what do you mean by "addressing all subclasses"?

[signal trail]

Hello, is adding an event to an animation in the animator the best way to assign hitboxes to a move?

I want to add hitboxes to specific frames and this has been the only solution I have found

[cosmic dagger]

animation events are a good way to call methods when something within that animation occurs. there is no best solution, but this sounds like a good one to use and test if it works for you . . .

[autumn pine]

Like missing reference error

[autumn pine]

Like put a different subclass script on different objects, but a main controller script with 1 reference to the main class

[steep rose]

NullReferenceExeption or NRE?

[wintry quarry]

Missing Reference means the object was destroyed

Are you sure it's that error?

You should share the actual code and the exact error message you are seeing

[steep rose]

how much of a performance drop if any would using rigidbody bullets from 5 to 10 people or ai and the bullets are shooting at a rate of a quarter of a second compared to translated bullets of the same size of people and rate?

just wondering since i will have to implement a bullet system soon

[rocky canyon]

physics on 20 - 40 objects per second as opposed to physics on 0 objects per second?

is that what ur asking? lol

[steep rose]

technically yes 😅

well

i would still be translating the same amount of bullets at the same size of people and rate of fire

[signal trail]

Thanks, im used to working by frames and the only way I can do it seems to be this way. I think I have a way to make it work with animation events.

[steep rose]

but instead i would have to check collisions with OverlapSphere and just delete the bullet on impact for the translated bullets

[iron wind]

rigidbody gonna be better, no need to reinvent the wheel

[autumn pine]

I should I'm just not at my PC at the moment

[wintry quarry]

There's no way to answer this, you have to test it

Most likely it would be faster than using scripts to manually move the objects though

[steep rose]

alrighty thanks for the input 👍

[leaden crow]

Is this a bug? I'm running into a minor issue where scripts attached to a deactivated parent object are still being called, giving me some weird errors
I can bypass this by running a manual check that the parent is deactivated, but shouldn't Unity do that by default?

[cosmic dagger]

what exactly is being called?

[leaden crow]

A function that shoots a bullet when the left mouse click is pressed

it was getting to this part and stopping since it couldnt access the prefab due to the object being disabled

[cosmic dagger]

you can manually call public methods from deactivated scripts. only certain unity update methods won't run . . .

[leaden crow]

I don't recall this bug happening before I updated to 2022 LTS though

[cosmic dagger]

did you debug to ensure it's being called? did the debug to ensure the script from the deactivated GameObject is calling a method?

[leaden crow]

The only major trouble it caused was reducing the bullets in the magazine of the reserve weapon but I can block access to it by manually checking if the parent is active

Ye

I put a Debug.Log that returned the name of the weapon the script was being called from

I could also tell the script was being accessed since ammo--; was being called in every left click

Even when the gun wasnt actually firing

[wintry quarry]

It's a bug - in your code, not in Unity's code

Look at the stack trace in your Debug.Log to see where it's being called from

Likely an input handler of some kind

[cosmic dagger]

to check if an object is deactivated is if (gameObject.activeInHierachy) . . .

[wintry quarry]

My guess is you are perhaps using the new input system and you subscribed to an input action via someAction.performed += SomeFunction;

and you never unsubscribed

[leaden crow]

Yes I am using the new input system

[cosmic dagger]

side note: you should format your code an can probably condense that if statement check . . .

[leaden crow]

But as I previously said it also didn't happen in previous versions I had the project on

And I was using the new input system aswell

[cosmic dagger]

are you subscribing to an event in Start?

[leaden crow]

yes

[ivory bobcat]

Any function can be called as long as it's accessible. The disabled script would just stop the Unity callback methods from occurring each frame - for the most part. The caller would need to evaluate if it's supposed to be called or not instead.

[wintry quarry]

So it's exactly as I said

Trust me - this has nothing to do with Unity versions

you are simply not unsubscribing your input listener appropriately

[leaden crow]

I get that
But then why did this bug not happen in 2019 LTS

I dont get that

[wintry quarry]

It either:

• did and you didn't notice
• You never disabled that object
• you never pressed the button after doing it
• your code didn't access anything destroyed or disabled before

[ivory bobcat]

You would not be able to convince folks of this. Likely the difference in behavior lies with the change of something other. Subscribing and unsubscribing to events isn't a pattern specific to Unity.

[leaden crow]

Havent touched the code that handles the firing since I wrote it in 2019 LTS

[wintry quarry]

Typical approach:

void OnEnable() {
  myAction.performed += MyListener;
}

void OnDisable() {
  myAction.performed -= MyListener;
}```
I do _not_ recommend using Start

[wintry quarry]

Look - the most likely thing here is you're simply misremembering some detail.

you're not going to convince us with this anecdote

[leaden crow]

Perhaps

[wintry quarry]

because everything you're saying is pointing towards an obvious error in your code.

[cosmic dagger]

please do not use Start to subscribe to events. you want to be able to subscribe and unsubscribe in—your—case you need to deactivate or stop a script or system from running. as Praetor mentioned, use OnEnable and OnDisable . . .

[leaden crow]

I'm switching to that as we speak

I didn't know those methods were a thing

[steep rose]

!code for whoever sent that

[ebon mist]

Does anyone know how i can fix my combo script from constantly triggering Attack1

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

[wintry quarry]

What do you mean by "constantly triggering" it?

[ebon mist]

Like when i spam click Attack1 Triggers over and over

I tried adding a timer but it did not help

[wintry quarry]

Ok that's not "constant" that's whenever you click

so what you are asking is how to add a cooldown

[ebon mist]

yes i guess so

but only for the 1st attack the other 2 are good

[wintry quarry]

Well first you should add some Debug.Log statements in here to see what's actually going on.

because as far as I can see - this comboStep variable and the correlated if statements should prevent Attack1 from triggering more than once

[ebon mist]

ok ill add some

Is there a specific spot i should put them?

[wintry quarry]

I would put them in each of those combo step if statements

[ebon mist]

ok

[wintry quarry]

inside PerformCombo

[steep rose]

quick question how would i be able to get the specific transform of a point in my array

    public Transform[] WPTransforms;

    [SerializeField] private int RandomPoint;

    private void Start()
    {
        RandomPoint = Random.Range(0, 4);
    }

    void Update()
    {
        WPTransforms[RandomPoint] = //something
    }

i am just now learning arrays

[wintry quarry]

WPTransforms[RandomPoint] is the specific transform

Transform example = WPTransforms[RandomPoint];```

[ebon mist]

All the combo steps are in the log i think im just clicking so fast its resetting to Attack1 before the animation finishes

[steep rose]

oh, alright

[cosmic dagger]

you already have it. the line in Update accesses the specific element in the array . . .

[steep rose]

yeah im not the best at arrays as you see 😅

i put them off for a while

thank you though

[wintry quarry]

well you need to decide how you want it to work. Do you want it to jump straight to the next animation without waiting, or do you want the user to have to wait for the animation to complete? Or what?

[ebon mist]

Yeah i want to keep exit time so the full attack plays

[wintry quarry]

then you should prevent the player from being able to attack again until the animation is finished

you can do this with an animation event for example.

[ebon mist]

Thats the part i dont understand because i Have a animation event that sets canAttack to true but it dosent work

[wintry quarry]

Well, canAttack is ALWAYS true

because your code never sets it to false anywhere

[ebon mist]

ooooh ok you think i should set it to false untill the animation event triggers it back on?

[wintry quarry]

yes

[ebon mist]

Ok i shall try thank you so much

[sour fulcrum]

Honestly no clue where this question should go since I guess it's editor related but kinda not,

What's the vibe on running IEnumators without a monobehaviour?

I've seen some examples online on how you can kinda run through them yourself but my initial testing of them seemed to produce results that ignored yields?

[eternal needle]

IEnumerator is a thing outside unity. unity uses them for coroutines. yields arent ignored, but they likely dont do what you think they do

[sour fulcrum]

Ah ok, probabably a good time for me to learn how they actually work 😄

For context im trying to do some webrequest/downloadhandler stuff for editor related things but was curious outside of that usecase aswell

[steep rose]

am i on the right track here to finding the transforms of the overlapsphere colliders?

    [SerializeField] private Collider[] overlapcolliders;

    Transform overlaptransforms;

    void Update()
    {
        overlapcolliders = Physics.OverlapSphere(transform.position, 50f, WPtransformmask);

        foreach (var hitCollider in overlapcolliders)
        {
            overlaptransforms = hitCollider.transform;
        }

        currentpointtransform = overlaptransforms[RandomPoint];

       distfrompoint = Vector3.Distance(currentpointtransform.position, transform.position);
    }

[frosty hound]

overlaptransforms is not an array or a list, so no, this won't work.

It should also be giving you an error.

[steep rose]

it is giving me an error, im currently trying to get it to work

would i make it an array then get the hitcollider array of transforms or just the transform

[frosty hound]

I don't know why you need to store all the transforms into another collection, you have them all in overlapcolliders

[steep rose]

i thought that gave me a list of colliders

oh, nevermind i think i figured it out

[steep rose]

thanks Osteel, you're a lifesaver!

arrays are tough, at least for me

[upper forge]

How do get a parent gameobject and find the child of that gameobject parent and then disable it ?

[cosmic dagger]

you get a GameObject by referencing it from the inspector, using Find methods, searching for its tag, or a component attached to it. once you have the GameObject, you can search through its children to find the specific child transform and access its gameObject property to disable it . . .

[upper forge]

i got it !

Is there anyways to set the transform of an animations that plays?
I have one playing on the main character but the position is way off

[near wadi]

again, !code

[cyan crag]

https://hatebin.com/cgghykmunu so this is my code and when i try to test my game it just goes on forever and ever

[swift elbow]

Using find methods are very inefficient and slow. you should reference your gameobject in the editor instead by making a public variable and dragging in the reference

[swift elbow]

i dont see how your code has anything to do with it. i think your editor is just bugger or slow

[cyan crag]

ok

[swift elbow]

try disabling domain reload in project settings, if its on

[cyan crag]

its off

[near wadi]

would the possibility of clearing Library help them at all, since they say they have restarted the editor several times to no avail

[swift elbow]

this happens to me sometimes whenever i have a large project that im working on, but it never takes more than 10 or 20 seconds

[swift elbow]

ive tried that but its never helped me so probably not

[near wadi]

ok, i leave it to you guys

[cyan crag]

same it normally takes 5 seconds to do that part of the compiling

[swift elbow]

what version are you using?

[swift elbow]

yeah this happens to me on a similar version

i dont think this will help, but you should try closing your project and deleting your library folder, like Hunanbean mentioned

[cyan crag]

where is the library folder im quite new to unity

found it

will this make me restart my project?

[swift elbow]

make sure you only delete that, and make sure your project is closed.

[cyan crag]

so i delete the library folder

[swift elbow]

after you delete it simply reopen your project and the files will regenerate on its own

[swift elbow]

yes, just that

[cyan crag]

i delete this

ok

ok so i reopen

hopefully this works

[swift elbow]

it'll take a few mins for the project to reopen
