You need to do yield return currentAnimation if you want to wait for it to finish

[woeful spire]

ah, should've clarified that the coroutine simply starts with teleporting the trail to the startpoint. It could just as well say trail.transform.position = Vector3.zero; or something like that.

I'd like to wait as little as possible, not even one frame if possible

[leaden ice]

Why don't you do that then.

stop emitting
Wait a frame
Teleport
Wait a frame
Start emitting
Start the animation```

[woeful spire]

that's what it's doing. The coroutine I'm referencing just teleports it to the start in the same frame it's called:

protected override IEnumerator AnimateFromTo(int index, Action<int> action)
    {
        Transform from = GetTransformFromIndex(index);
        Transform to = GetTransformFromIndex(index, 1);
        float distance = Vector3.Distance(from.position, to.position);
        float fullTime = distance / speed;
        float elapsedTime = 0;

        while (elapsedTime < fullTime)
        {
            float elapsed01 = elapsedTime / fullTime;

            trail.transform.position = Vector3.Lerp(from.position, to.position, elapsed01);

            yield return null;

            elapsedTime += Time.deltaTime;
        }

        trail.transform.position = to.position;

        action(1);
    }

[woeful spire]

private IEnumerator StupidOneFrameWaitCauseTrailRendererSucks()
    {
        trail.emitting = false;

        yield return null;

        trail.transform.position = GetTransformFromIndex(GetIndex()).position;

        yield return null;

        trail.emitting = true;

        currentAnimation = StartCoroutine(AnimateFromTo(GetIndex(), ContinueAnimation));
    }

Rewrote to this exact structure but the same thing occurs.

after some further experimenting, it seems that it's due to something else so I'm gonna keep at it for a while...

[dawn nebula]

I have this simple 2D projectile gameobject.

I want to rotate it based on the direction of a vector, aligned through the tail. How do?

My ability to harness the power of Quaternions has much to be desired.

[hexed pecan]

In 2D it can be as simple as assigning the direction to transform.up or transform.right

[golden vessel]

Will that condition sound.clip == musicAudioSource.clip be true if they come from different objects in different scenes, but they both come from the same asset?

Or should I compare some string related to the clip

[leaden ice]

That is a reference to the asset

As long as it's the same asset it's the same reference

[mighty granite]

I'm having a lot of trouble trying to draw a simple line between to canvas elements.. Does anyone know how I could make a line render between two UI elements like shown in this picture with the blue line?

I was able to use line renderer for 3d objects to create this in 3d very easily.. but there doesn't seem to be an equivalent to use for 2d canvas..

[golden vessel]

Alright, Thanks for theinfo

[cosmic rain]

Either don't use a canvas ui for it, or implement a custom canvas line renderer.

There's also a unity ui extensions package available on GitHub. I think it has a canvas line renderer component. Google it.

[mighty granite]

Just seems wild to me that it's not part of the standard library. I think there is another layer to my issue though and that is that I have these objects nested within 2 layers of panels. It seems like Unity only keeps track of a child UI objects relative position to their parent. I suppose all that I really need is the objects position on the screen translated to world coordinates but it seems this relative position is messing up that calculation with the built in Unity functions. Is there a way around this nested UI object issue?

[cosmic rain]

Not sure I understand what the issue is.

If you just need world position of an element, use transform.position🤷‍♂️

[verbal pebble]

Running into an issue with my grounded checks and jumping in my prototype.

I was originally using the controller.isGrounded() to determine grounding, which wasn't ideal due to its' unreliability, and 'work-arounds' meaning that the player would still slowly slip off sloped surfaces.

I'm now using Raycast.Hit in the isGrounded bool. Problem is that now, it seems to be interfering with jumping, it immediately still finding that the player is grounded and preventing the jump from taking place.

I looked around online for a bit, but couldn't quite find anything to solve the issue that I'm having here. Raycast itself is incredibly short (only takes place after the soles on the character's foot and lasts for 0.01f), but it still manages to prevent jumps from happening.

Is there any way to disable the raycast checks when jumping takes place to avoid this?

[mighty granite]

UI Elements don't seem to work like that... they don't have coordinates in world space, they are all positioned relative to their parent game object on the canvas. You can see that even those these two elements are in different X,Y coordinates on the screen, their X coordinates are the same because they have the exact same X offset inside their parent panels

[cosmic rain]

Of course they do. They have world space position corresponding to their position on screen.

What you see in the inspector is not world space position

It's the anchored position afaik.

Same as you don't see world position on normal transforms(you see local position)

[leaden ice]

It depends on the canvas render mode you're using. Screen space camera canvases are simpler

[mighty granite]

So these are the same two UI elements as in the previous images. You can see the two anchoredPositions here and their X coordinates are both 0 and only Y is set (I'm presuming this is the offset y-coordinate within it's parent).

[cosmic rain]

Expand the "base" transform class...

Rect transform extends the regular Transform.

[verbal pebble]

Any idea why my while loop would be freezing the editor?

[golden vessel]

Time.time < maxJumpTime I suppose

[verbal pebble]

Tried that, though the while loop doesn't seem to trigger

[golden vessel]

Cos Time.time is not 0

When you start

The value you want to check is Time.time-startTime

[verbal pebble]

oh yeah, originally it was time - startofjump

[golden vessel]

where startTime is Time.time at the frame you jumped

[mighty granite]

Time.time will always be iterating up. I think you want to capture an instant of time and compare it with the current time to see how much time has elapsed, if it that is greater than you maxJumpTime, then you could jump

[quartz folio]

you just want an if statement

Do not use a while loop unless you want the logic in it to run to completion in one frame, or are yielding inside of it somehow

[verbal pebble]

so the logic is meant to make it so the player will jump higher if space is held, but if i was to use an if loop, that immediately makes the player jump higher regardless if i just tap space or not

[leaden ice]

if is not a loop

[verbal pebble]

if statement, sorry

but yeah, in my case a while loop just doesn't trigger at all

[leaden ice]

You need to change how you think about this.. remember update is running once per frame

[quartz folio]

You have a fundamental misunderstanding of how this works

[leaden ice]

You need to think about how things progress and change over time.

[quartz folio]

A while loop will run to completion in one frame. The code inside of it will be looped over continuously until the condition is false. By looped over continuously I mean the code does nothing else until it is done.

[verbal pebble]

ah shit, that explains it then

[leaden ice]

Time does not advance.
Frames are not drawn
Other code does not run, etc.

[verbal pebble]

Could it be run separately, say in an ienumerator?

[leaden ice]

Yes

That's the point of a coroutine

[verbal pebble]

I already have one set up to disable ground checks on jump, so yeah

[quartz folio]

Update is already a loop through, a loop that is returned to each frame. So if you just use an if statement it will check that logic each frame and perform it if it's true

[verbal pebble]

oh, odd

It only ever triggers once, and that's even if the space bar is simply pressed as opposed to held over the duration of the jump (though that's likely because i haven't set up a minimum time elapsed in the conditions)

[quartz folio]

and presumably that's because Time.time becomes greater than maxJumpTime

which, if maxJumpTime is say, 2, then you have two seconds at the start of your game until you cannot jump again

[verbal pebble]

It might be because it's part of a contained Jump() void, which is then executed in update when the player jumps

[verbal pebble]

oh?

yeah, mine's already at a second and a half, so there's plenty of time for it to presumably run multiple times

[mighty granite]

I believe that the new Input System has a way of differentiating "Long Press" from "Short Press" and I think that is what you would want in this scenario

[verbal pebble]

I haven't actually given the new input system much of a shot yet, though I could take a look at it

IIRC the old and new input systems can be used interchangably, right?

[leaden ice]

All of this can be solved with a few if statements, bools, and floats in Update

[mighty granite]

Just checked looks like they don't have a good way of handling this out of the box so you would need to do some of your own logic anyways :/ https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/Interactions.html

[verbal pebble]

Ah damn, all good

Hello, is there a way not to implement every override method in the child a class, since the child only uses some of them ?

[tired forum]

So I have an airship that I am using physics to move (so that I can have a little more of a floaty feeling). What is the best practice for handling the fact that I can't have a mesh collider w/ a rigidbody and Kinematics ?

Should I do it using a second physics scene .. do all the forces over there then translate position movements to the first scene? Or should I go with a compound mesh?

[leaden ice]

Look up abstract vs virtual methods

[trim heart]

Helloop
Some one know why my game editor is being activated when I'm supposed to be on the game scene?

It makes the testing really difficult
And not only happens with the pause scene button

[leaden ice]

you have "Error Pause" enabled in the console window and you have errors occurring

therefore the game is pausing

Also you have disabled errors in your console log so you're not seeing them. Notice how errors are toggled off here (you have 4 errors in console in this screenshot)

[chilly prawn]

Hey, so i am working on a 2d game where i've inserted different animations for different combos. I want to change the hitbox for every animation. Is there any other way to do it without having to change it frame by frame?

Note: The attack animations look similar to hollow knight's animations. It's just a white slash animation and that is the hitbox that i want to change.

(edit: Do kindly ping me when replying.)

[mellow sage]

Hello !
For my last year in my school, I've got a project to do, and I wanted to recreate the Solar system with forces on Unity.

My forces are Speed and Acceleration

public double Vitesse(GameObject planet)
    {
        return Math.Sqrt(Constants.G * Constants.SolarMass / (Vector3.Distance(planet.transform.position, Soleil.transform.position)*10000000));
    }

    public  double Acceleration(GameObject planet, GameObject B)
    {
        return Constants.G * B.GetComponent<Data>().mass / (Vector3.Distance(planet.transform.position, B.transform.position) * Vector3.Distance(planet.transform.position, B.transform.position) * 10000000);
    }

and they are called in a FixedUpdate

Vector3 v = Vector3.Cross(Soleil.transform.position - transform.position, Vector3.up).normalized;

gameObject.GetComponent<Rigidbody>().velocity = (float)Vitesse(gameObject) * Speed * v;

GameObject[] items = GameObject.FindGameObjectsWithTag("SpaceItems");
foreach (GameObject item in items)
{
  if (gameObject != item)
  {

    gameObject.GetComponent<Rigidbody>().velocity += (float)Acceleration(gameObject, item) * Speed * VectorAToB(gameObject, item);
                
  }
}

[plucky inlet]

you want the solar system, then you have to think about angular velocities

[mellow sage]

It seems to work for all my planets, they are rotating around the Sun, and seems also attracted to all planets at the same time (all the solar system is moving in my scene), but now I try to add the Moon to rotate around the Earth, and it seems that it doesn't work

[plucky inlet]

Oh you are working with mass and gravity for each planet if I get this correctly?

[mellow sage]

oh really ? i've did something like that

[mellow sage]

yup exactly

with white it's better x)

[plucky inlet]

than you have to alter your Vitesse function to not only take in account of your soleil origin but also the earth being its main attractor

your Soleil.transform.position is S, the sun right? but the moon does not rotate around the Sun but the Earth, right?

[mellow sage]

ohh

yeah thanks i'll try that !

[plucky inlet]

Physically correct the sun will still attract the moon "at some point", but for the sake of simulation, I do not think you want to calculate that too 😉

[mellow sage]

mmmh because Sun mass is >>> at Earth mass, it makes the moon goes really slow 🤔

[plucky inlet]

But the moon is not big enough to be affected the same way as earth is, so the mass is a big factor of how much the moon is affected by the sun

I mean looking at it over millions of years, the moon will crash into earth probably one day 😄 but nothing you want to simulate I guess 😉

[mellow sage]

ok ok so I've maybe have a problem somewhere else in my code, because with something that makes the moon's speed affected by the Earth's mass and not the Sun as other planets, the Moon is almost motionless

[plucky inlet]

Well the moon is basically travelling at the same orbit as earth does, cause the sun is of course affecting the moon. but the escape velocity is just too high to like let the moon leave earth. It eventually will one day or the "wobble" will flatten and we meet the moon here 😄 but for now you would have to guarantee, that the moon is copying the earths orbit + the earths attraction

[mellow sage]

ohhhhhhhh you gave me an idea ! I could maybe calculate the escape velocity to make that !

I'm gonna look for that, thanks a lot ! :)

[plucky inlet]

Let us know how it worked out, super interesting topic 🙂

[hard tapir]

Why this works in editor, but in game it has no effect
if (Input.GetKey(KeyCode.Alpha4))
{
_input.cursorLocked = false;
_input.cursorInputForLook = false;
Debug.Log("Cursor unlocked and input for look disabled");
}
else
{
Move();
_input.cursorLocked = true;
_input.cursorInputForLook = true;
Debug.Log("Cursor locked and input for look enabled");
}

_input is script in first person asset from Unity technologies

[cosmic rain]

Are you building the right scene?

[plain coyote]

not sure which channel is the best for my question:
but I am having a lot of clipping when I am using my FBX model, it is a 3D model for a real-building, so it is a bit complex, but when I navigate around it, a lot of clipping happens and it is very annoying, any ideas how to stop this?

should mention in the editor

[cosmic rain]

What do you mean by "clipping"? Your character is clipping into walls or something?

[plain coyote]

no, when I navigate in the (scene) editor, around the 3D model.

[cosmic rain]

You could adjust the scene camera settings.

[hard tapir]

Yes?

[plain coyote]

I tried that, but there is only the main camera, which happens when the game run, not while in editor mode.

[cosmic rain]

Aight. Do you see the debugs in the console?

[cosmic rain]

First, try pressing F to focus on a selected object. If that doesn't help, you can adjust the scene view camera at the top right of the scene view toolbar.

[thick plume]

I have 2 GameObjects on the same layer. Both have a Mesh Collider but when they are on top of each other my code doesn't run.

    void OnTriggerEnter(Collider col)
    {
        Debug.Log("it works!");
    }

    void OnCollisionEnter(Collision col)
    {
        Debug.Log("it works!");
    }

currently the Is Trigger options are turned off on both mesh colliders, but if I turn them both on it still doesn't trigger the code.

[mellow sage]

@thick plume do your GameObjects have a rigidbody ?

[thick plume]

yes

[mellow sage]

and, just to know, if you use a OnCollisionStay ?

[thick plume]

i don't, is it a method?

[mellow sage]

same as OnCollisionEnter

[thick plume]

i see, i don't

[mellow sage]

yeah but, idk if it's possible, but maybe when you start your scene, the GO are already in collision 🤔

[thick plume]

shouldn't it trigger the method when i load the scene then

[hard tapir]

Yes!

[mellow sage]

idk at all :/

[thick plume]

i see

[cosmic rain]

In a build I mean.

[plain coyote]

thank you ^^

[hard tapir]

What is build?

When alpha 4 presses then those two bolean become false

[cosmic rain]

You said the movement doesn't work in a build..?🤨

Or I assumed that you said that...

[hard tapir]

No, movement works but mouse cursor doesn't

[cosmic rain]

In the build?

[hard tapir]

Yes

Simply

It works when at the begining I set up cursor lock true and cursor locked to true

And in opposite way

But when I want to handle that in script then 💥

Not working

[cosmic rain]

I really don't understand what the issue is.
I'm also confused if we're talking about play mode or build...

[hard tapir]

Im gonna create video ok?

[cosmic rain]

Ok

[rugged plume]

hello fellow unity users, ive become aware of a few different ways to do car physics, and im not sure which one to pursue, there is the sphere method, and the wheel colliders, and im sure there are many other methods.

im trying to recreate the kind of physics from Sega Rally Championship or other Rally type racing game, which one would be better for this?

https://youtu.be/_x_E1wUvzb4?t=95

here is a reference for what im talking about

theres pretty much no drifting, just angling

[potent sleet]

man this takes me back..

[potent sleet]

Yeah i think NFS did the whole "drifting" thing

Another option is to also use Raycasts to kinda create suspensions

[rugged plume]

yeah, that and a few like, arcadey games

[potent sleet]

the Unity Car in standard Assets is a good starter imo

you can play and tweak

[cosmic rain]

Damn, I remember that game. And some chopper rescue missions kind of game... What was it called..?🤔

[rugged plume]

unity car?

is that like

wheel colliders?

[potent sleet]

Indeed

[potent sleet]

you can get some decent results with some tweaks, also asset store has a few good Free ones

[rugged plume]

thanks!!

im gonna go check that out

[potent sleet]

here
https://github.com/jamschutz/Unity-Standard-Assets/tree/master/Standard Assets

they took it down from asset store for this one

just open the project and it's the Vehicles scene

[neon yarrow]

Anyone know why Unity is throwing issues related to not finding Editor assemblies during builds, despite the file being clearly located in an Editor subfolder?

Assets\3rd Party Assets\DreamOS - Complete OS UI\Editor\Scripts\InitDreamOS.cs(3,19): error CS0234: The type or namespace name 'Presets' does not exist in the namespace 'UnityEditor' (are you missing an assembly reference?)

[hard tapir]

I hate this error

First you can try using namewhereitis;

Or you add assembly

[neon yarrow]

Can you elaborate on this?

[hard tapir]

Script which is referenced, where it is

[deft timber]

hey, im having a sequence container with enemies that im instantiating via addressables, the enemies are also marked as addressables, altought they aren't loaded, they just sit in that Sequence Container which is being loaded asynchronuesly. How can i release the memory that the enemy takes when the enemies dies? I guess enemy.ReleaseInstance() when he dies won't work, since I didint load him by addressables?

[neon yarrow]

So the directory of the file causing the issue is Assets\3rd Party Assets\DreamOS - Complete OS UI\Editor\Scripts\. The missing namespace is Presets which is from the UnityEditor namespace.

But the point is that scripts under Assets\3rd Party Assets\DreamOS - Complete OS UI\Editor\Scripts\ aren't supposed to be compiled during builds.

Because it's inside the Editor subfolder.

Which is a special subfolder https://docs.unity3d.com/Manual/SpecialFolders.html

[hard tapir]

Idk how to solve this

[weary sapphire]

You don't have any pauses inside the while loop so it just runs to completion in a single frame. The yield return null line should be inside the loop.

Hi guys, I'm trying to change item scale to fit bigger character. Item has skinned mesh renderer on it. As of my understanding I need change skinned mesh renderer scale, but it doesn't work. Anybody know how to achieve that? maybe I taking wrong approach?

[potent sleet]

do you mean with code?

[thorn ravine]

Yes

[weary sapphire]

its always got to be the easy things that confuse me aint it? lol, cheers man

[thorn ravine]

Yes

[potent sleet]

I don't understand why you need to change the skinned mesh renderer instead of just scaling transforms ?

[thorn ravine]

Well to be honest, I tried scaling transform as well, but it doesn't work

[potent sleet]

can you explain maybe the setup ?

what do you mean "doesn't work"

[thorn ravine]

Well I have a character, which has script which allow to equip items on it. So script works fine, but now I have another character which is bigger. So I want to be able use same items , but scale them before equipping on bigger avatar.

[thorn ravine]

It doesn't scale to the values, which was set in the Transform

[potent sleet]

quick dirty way you could maybe pass the scaling to the object once you pick it up , each char sets a diff scaling ratio mayb

[thorn ravine]

What do you mean by passing scaling to the object?

[maiden breach]

how are you setting the scale in the transform?

[thorn ravine]

In Edit Prefab mode just changed values

afterwards i tried to set transform on skinned mesh renderer

like this

                    var addedItemSkinnedMesh = partsInstance.GetComponent<SkinnedMeshRenderer>();

                    addedItemSkinnedMesh.transform.localScale = new Vector3(5, 5, 5);

[maiden breach]

so you have a separate prefab for large character? If not, you probably just want to leave this at one character's scale and scale it dynamically through code based on who picks it up

[steady thicket]

I'm working on a 3D pathfinding system that uses a modified version of the A* algorithm. I'm currently using a custom implementation of a Skip List for the "Open Set". Does anyone have any suggestions or resources about possible better data structures? I've tried a Priority Queue, Sorted List and Sorted Dictionary and they are all varying degrees of slower so I made this skip list but I'm not sure that it is the best option for this sort of thing.

[maiden breach]

as for your code, it looks like it should work. Maybe use a paste site to paste the whole script for context?

[thorn ravine]

Yes I have another character on another prefab. Problem is with scaling, it just doesn't apply to the items

[maiden breach]

I meant item prefab.

[potent sleet]

isn't that kinda what I said earlier :p

[maiden breach]

For sure. I'm just doing a cover song lol

[thorn ravine]

Yes, Item is in separate Prefab, which I assign/equip on character during runtime

[maiden breach]

Still not what I meant, but let's look at the code

[potent sleet]

You can have a separate script that only deals with scaling just on pickup methods

[thorn ravine]

https://pastebin.com/HT4bd0c2

[maiden breach]

ok, first off you don't need to scale each child individually

scale is inherited through the hierarchy

also, you don't need to access transform through skinnedmeshrenderer. It exists on GameObject as well

[swift falcon]

Hi, Im looking into using unity for an emulation front end, but theres a couple things that Im not really able to get a clear answer for.
Is it possible to:

• Open a new window like you can with javafx or similar and send data to and from?
• Display items in a grid or list based on info pulled from a database (Title, image location, that sort of thing)
• Create drag and drop behavior and/or a file selection window for files and read those files in runtime?

[maiden breach]

@thorn ravine this isn't enough information. Idk where _addedPartsInstances is being set. Could be an empty array in which case no scaling would happen.

should just scale the root item object anyway

[thorn ravine]

It is in the ReassignMesh method. It is in the Pstebin

[thorn ravine]

That's the thing that it doesn't work that way

All addedPartsInstances are Initialiazed into avatar object

[maiden breach]

ah ok, yeah I see where you're adding them

[thorn ravine]

That's how it looks like in the hierarchy in Play mode

So item equipping script works fine, it just the scaling doesn't work

[maiden breach]

really, this should all be as simple as:

Transform anchor;
float scale;

public void OnPickedUp(Transform itemTransform){
  itemTransform.localScale = Vector3.one * scale;
  itemTransform.SetParent(anchor);
  itemTransform.SetLocalPositionAndRotation(Vector3.zero,Quaternion.identity);
}

[nova python]

Why is the max x value 1.23 and min value -0.16 at the edge of the screen where my mouse cursor is

Is it due to my screen size?

I thought Max would be 1 and min 0 no matter the screen size

[humble thistle]

I could be wrong but maybe try using .Magnitude

[rugged plume]

https://youtu.be/AnrzExvmTgI

does anyone know how they pulled off this camera effect?

im not sure what they are actually doing

[humble thistle]

I would assume cinemachine with a spline

[rugged plume]

maybe, it doesnt seem to be running along a path

[humble thistle]

I personally don't have the experience of doing that however I know it's something that it can do

[rugged plume]

also seems to keep a consistent distance from the centre

[humble thistle]

It looks like it'd just be a circular spine around the car to me tbh. Splines can do some wild stuff

[rugged plume]

ohhh! misunderstood

well i mean, like how does it know when to rotate where? thats where im lost

[humble thistle]

You do mean the intro at the start of the race right?
Just making sure I'm on the same page as ya

[rugged plume]

nah just like in general

he has a "slide" mechanic present in sega rally

and like,

it rotates the whole vehicle

but like, it doesn't rotate the camera

until the turning has adjusted properly

watch the gameplay, itll show

[humble thistle]

OH

In cinemachine you can have your camera follow and object, you want it to follow a child object and not the parent then change the transforms of the parent when you want the camera to rotate

I had to figure this out for myself in my project I'm working on

So when he's doing the drifting he is only changing the transform on the mesh of the object, not the parent and probably has a separate invisible child object on the parent the camera follows

[rugged plume]

well its not really drifting but yeh i get what you mean

[humble thistle]

It's the biggest part of it really, so once you're able to get the mesh rotation separated from the camera rotation you have the freedom to rotate the car however you want with the parent object doing the real turning

It's kinda hard to explain but it's two parts, the drifting does slightly rotate the whole object but the mesh needs to turn wayyyyy more

So like, I think the best example I can come up with with drifting is
Let's say when your turning your car your mesh is also turned but with a "Drift Multiplier" to it so it turns that much more than when the camera turns

It'd be your offset between the rotation of the car and the rotation of the camera

[rugged plume]

wait so id like maybe lerp between the current camera rotation and the rotation of the car more or less

that actually

makes a lot of sense

[humble thistle]

So you'd have the rotation of your whole game object (rotate the parent) with your input method, then call a function that rotates the child mesh as well with an offset multiplier

It probably wouldn't be anything close to perfect but it's a good start

[rugged plume]

okay yeah thats a good solution

[humble thistle]

just make sure you make a separate game object for the mesh that is a child under the parent.
I can't over state how long it took me to understand this

[rugged plume]

ill make sure, ive had that happen before

[hard tapir]

@cosmic rain

[humble thistle]

👌 Gl on your project

[hard tapir]

error, can you help me? as you can see when I hold alpha key then cursor locked and input is false, however in game it has no effect. Mouse is still in the middle of the screen(it is its behaviour if cursor locked and iput is true)

[cosmic rain]

Put a debug in the if and else blocks.

[hard tapir]

here

[humble thistle]

Also one other thing I thought of, multiply the whole car thing by a magnitude of the car's velocity so when your car doesn't look like it's drifting at low speed

[rugged plume]

Oh dw, I'm not do8ng drifting

[humble thistle]

Ah gotcha

[rugged plume]

Thank you btw!!

[cosmic rain]

So the issue is that the cursor is visible?

[humble thistle]

Try clicking when it's supposed to be hidden.
In the editor the cursor acts a little different so you can still use it

[hard tapir]

no, that cursor cannot click button

[cosmic rain]

Wat...

[hard tapir]

it is wierd right

[humble thistle]

I'm confused I'll let you guys figure it out, I don't wanna cause too many cooks

[hard tapir]

here

[cosmic rain]

No it's not. I thought you had a more serious problem...

[hard tapir]

manually

[cosmic rain]

What part is supposed to lock the cursor? Do you understand?

[hard tapir]

it works, you can click on button when you disable those variables

[cosmic rain]

What line in your code is responsible for locking/unlocking the cursor?

Honestly, this should be in #💻┃code-beginner

[hard tapir]

wait

those two booleans

            {
                _input.cursorLocked = false;
                _input.cursorInputForLook = false;
                Cursor.visible = true;

            }
            else
            {
                _input.cursorLocked = true;
                _input.cursorInputForLook = true;
                Cursor.visible = true;
            }```

[cosmic rain]

Wrong.

[hard tapir]

_input is btw where those booleans are

[cosmic rain]

Why would setting some random bools affect the cursor?

What is the unity API for un/locking the cursor?

[thin aurora]

You know Cursor.visible is true for both of those?

[humble thistle]

Yeah I was gonna say

[hard tapir]

yes, so I can see where it is bruh

[thin aurora]

Right

So the issue is that the mouse is not properly locked?

Pretty sure this is how it works in the editor. You should test it in an actual build

[hard tapir]

{
    public class StarterAssetsInputs : MonoBehaviour
    {
        [Header("Character Input Values")]
        public Vector2 move;
        public Vector2 look;
        public bool jump;
        public bool sprint;

        [Header("Movement Settings")]
        public bool analogMovement;

        [Header("Mouse Cursor Settings")]
        public bool cursorLocked;
        public bool cursorInputForLook;

#if ENABLE_INPUT_SYSTEM && STARTER_ASSETS_PACKAGES_CHECKED
        public void OnMove(InputValue value)
        {
            MoveInput(value.Get<Vector2>());
        }

        public void OnLook(InputValue value)
        {
            if(cursorInputForLook)
            {
                LookInput(value.Get<Vector2>());
            }
        }

#endif


        public void LookInput(Vector2 newLookDirection)
        {
            look = newLookDirection;
        }


        private void OnApplicationFocus(bool hasFocus)
        {
            SetCursorState(cursorLocked);
        }

        private void SetCursorState(bool newState)
        {
            Cursor.lockState = newState ? CursorLockMode.Locked : CursorLockMode.None;
        }
    }

}```

this is where those 2 booleans are

[cosmic rain]

What makes you think they affect anything?

I'll ask again, what is the unity api for unlocking the cursor?

[hard tapir]

api?

[cosmic rain]

API. Methods and properties that unity provides for you to use.

[hard tapir]

in that script?

[cosmic rain]

In general

[hard tapir]

SetCursorState()

[cosmic rain]

That's "in this script", not "in general"

[deft timber]

that's your function

[humble thistle]

The api is Cursor.lockState and it looks like he is probably just never actually calling that function from the code he's sent

He's just setting a bool

[hard tapir]

wait that the issue

[cosmic rain]

I hoped for them to get there on their own though

[hard tapir]

I wonder where is that function called /..

So I have to call that function?

[humble thistle]

Yep..
I'd highly recommend reading some resources about C# so you can get a better understanding of how the language works instead of copy and pasting some code.
Unity Learn is a wonderful place for it: https://learn.unity.com/

No he never called the function that he has to set the lockstate

[hard tapir]

ah

im stupid

[humble thistle]

There is code there, it was just never being ran

[rustic ember]

How can I have a script as a variable? It needs to be able to have any script as value not just one class

Wait can I just use cs MonoBehavior myScript?

[maiden breach]

Ah I see

[humble thistle]

You should just be able to create a variable by typing the name of the script.
Or are you trying to have one that global one that can referenced in the whole scene

[rustic ember]

I want to specify what script from the inspector

[humble thistle]

Oh just make it a public variable

It will show up in the inspector then once it's compiled

[leaden ice]

What are you trying to accomplish here? Sounds like an XY problem right now.

[rustic ember]

I think I might have explained it badly. It needs to be able to hold any script (not just a type of PlayerController fx.)

[leaden ice]

What will you do with the information of which script is assigned?

[thin aurora]

All your scripts derive from MonoBehaviour, so that works

[leaden ice]

It's not the same

[thin aurora]

You can go one lower and check for Component, or even Object

[leaden ice]

That's a reference to a particular instance of a script

not to the script itself

[rustic ember]

I could write cs PlayerController controller But I need something like this:

AnyScript script``` I need to store a list of monobehavior scripts to add to another object when the scene loads

[hard tapir]

Im learning unity 3 years

As a hobby

Im still student

So school is priority

[leaden ice]

Why don't you just do cs public GameObject example; which would be a prefab containing all the scripts you want. Then just instantiate that prefab.

instantiate it as a child of the other object

[rustic ember]

Thanks for the suggestion. I'm afraid it won't work in my case though. I have scripts that add different behavior to the object. The player chooses what scripts should be put on the object

[hard tapir]

Thanks you so much!!!!

[leaden ice]

The simplest approach here would probably be an enum then

[thin aurora]

But why?

What is the point

[rustic ember]

Does it matter?

[thin aurora]

Yes

Can't you make a generic method?

[humble thistle]

It feels really overly complicated so we're trying to figure out if there is a better solution

[thin aurora]

You know context goes a long way

Right now allowing the user to input any script is very confusing

[rustic ember]

What do you mean? I have one object. It can have 50 different behaviours depending on what script is attached to it. I need a way for the player to choose

[leaden ice]

public enum MyEnum {
  A, B, C
}

Dictionary<MyEnum, Type> dict = new() {
  { A, typeof(AClass) },
  { B, typeof(BClass) },
  ... etc.
}

public MyEnum[] componentsToAdd;

void AddStuff() {
  foreach (MyEnum e in componentsToAdd) {
    someObject.AddComponent(dict[e]);
  }
}```
@rustic ember

something like this

[humble thistle]

Your best bet would to have a manager script and have all the children scripts active or deactivated from the parent

[thin aurora]

So how are these behaviour defined? Do you have interfaces for them? Abstraction?

[rustic ember]

Truth to be told, I've never used dictionaries before so I'll definitely have a look at how they work. Thank you, I really appreciate it 🙏 🙏

[cosmic rain]

What you refer to as "script" is either a text file containing your code or a C# type. Neither of which can be serialized and then used easily the way you expect.

[stable rivet]

people are trying to get to the root of your problem because it's possible to yield a better implementation than the road you're currently going down.

see: https://xyproblem.info/

[rustic ember]

No clue what you mean. I have one called HealthSystem, one called Movement, etc.

[maiden breach]

I'd just use an interface like IRunBehaviour

[thin aurora]

I don't think you're going to have a good experience creating such a decoupled system if you have no idea what an interface is 🙃

[leaden ice]

In simple terms this just lets you quickly get the correspondoing type for an enum with dict[e]. THink of a Dictionary as an array that uses any type you want as the "index" instead of an int

[rustic ember]

Probably true. But there is no way to get good at something without first learning it. No one knows everything from the start, right?

[thin aurora]

True, but we'd love to give a better solution if there was more context to work with

[rustic ember]

Awesome!

[rustic ember]

The solution provided by PraetorBlue was just what I was looking for

[cosmic rain]

What I'd do is use an SO to define the behaviors(some people might be mad about it) and reference them in a list on your object.

[rustic ember]

Actually that is not a bad idea. I kind of like being able to turn on and off each script during runtime tho

[cosmic rain]

Well, you'll just need to implement that part in your code.

[maiden breach]

Add/Remove item from list is analogous to enable/disable monobehavior in the scene

[rustic ember]

I guess you're right. I hoped that there was a super simple solution I didn't know about

[hexed pecan]

Yeah apparently for some people it's blasphemy to have any logic in your SO 😅
I think its valid

[cosmic rain]

The way you imagined it at first is kind of metaprogramming. It's not a simple concept.

[thin aurora]

Isn't the whole reason of a SO to have preset data and logic in it? Why would it be wrong?

I assume it's not as organised?

[maiden breach]

Some people believe it should only and ever be immutable data.

[stable rivet]

i try not to do this with SO's purely because my web dev background makes me feel super dirty to mix data with logic. I end up usually making a plain C# class that can take the SO and do whatever it needs to to it

[thin aurora]

I would argue that you should use it for that, and then put any actual logic in a Monobehaviour. That way all actual logic remains in Monobehaviours

Then again, who cares

[potent sleet]

isn't SO just a fancy POCO, I just treat it kinda like a regular class already

[hexed pecan]

My SO-based AI graph begs to differ (you can instantiate SO's just like monobehaviours)

@thin aurora

[thin aurora]

Never said it not to work 😛

[rustic ember]

What do I do here?

[leaden ice]

read your error

and probably add using System;

[late lion]

I think the best way to think of SOs is this:
MonoBehaviour is how we create our own custom component types,
ScriptableObject is how we create our own custom asset types.

There are lots of asset types with logic, like AudioClip, Material, etc...

[rustic ember]

Yep. Thanks again

[stable rivet]

could be, whatever you want. i prefer to keep my SOs as models for immutable data and have separate entities that are exposed to the rest of the app. for instance, i'm currently working on a deckbuilder whereby the SOs are the card as they would be stored using a regular old db. the separate entity can then be manipulated into whatever the user does during the run (i.e upgrades). feels a lot cleaner that way. again that works for this project, but im not terribly opposed to logic creeping into SOs as and when it feels appropriate

again though, whatever way works for whatever

[thin aurora]

And as with all c# related things: there are dozens of ways to tackle a problem, and it really does not matter what you do. Just stick to it. This includes ScriptableObjects, however you use them.

[hexed pecan]

All of these use cases make sense 👍 I just don't like the "youre using SO wrong" that I occasionally see

[left sable]

hey, a question here about good practice for code order of execution.

I'm creating a script that executes an attack. When the hitbox gameobject connects with an enemy, it sends that information back to the player. The player then activates its own hitstop function to make the attack connect look dynamic, with slowdown etc.

Currently attack executes through a switch function that checks the current attack state: windup, active frames, recovery.

Is it okay to just have that hitstop/attackconnect function take place in the same switch function as the above? Or should I create a separate "attack connect" function that executes?

Reason is that it's simpler and more readable to keep all the attack logic in the same switch function. But I'm worried that because it's receiving data from a different script (the hitbox gameobject) there might be a delay in execution between the main script and the hitbox object.

[steady thicket]

Just going to bump this once since no one responded and there are some more people around now in case anyone has any advice. I know it is a very specific question and I'm probably just going to have to experiment more, but I thought it's worth a shot lol.

[buoyant crane]

What’s a skip list? If you’re just looking for a data structure that’s the most optimal for a* then it’s a min-heap. more info: https://youtu.be/3Dw5d7PlcTM?list=PLFt_AvWsXl0cq5Umv3pMC9SPnKjfp9eGW

[idle flax]

Hey, I have an issue. My particle collision system only uses callbacks when it collides with itself. The particles collide with objects in the world just fine, but it doesn't send any messages to my script except for when it collides with itself. Here's my collision setup:

When I set it to not collide with itself, no collision messages get sent.

[steady thicket]

I think that is what my Priority Queue implementation uses (this is what it looks like: https://paste.ofcode.org/sJp3qM3KKHv7igk3cPShkr) but I'll take a look, maybe mine is just a bad implementation. A Skip List is a neat data structure that does weird probabilistic stuff I'm not 100% sure I understand (wikipedia page: https://en.wikipedia.org/wiki/Skip_list my current implementation of it: https://paste.ofcode.org/mTvbZHAikkVbKDiGrN4Xyf). In my testing my pathfinding is about three times as fast using this implementation of a skip list vs. this implementation of a Priority Queue. I'm hoping maybe there is an even better data structure I could use that is perhaps as much faster than the Skip List as it the Priority Queue.

[buoyant crane]

i’ve got to go for now, i’ll take a look at it later

[sturdy venture]

Hey Guys, I've got an issue which has me lost (Pretty sure i'm actually just being blind). I'm raycasting from mouse through camera to hit a Texture3D which i'm then stepping at the hit direction through until it hits a specific value, the latter works perfectly however the raycast direction is completely wrong when the object is not in (0,0,0), It's rotation and camera position dont matter and seem to work flawlessly, heres the important code for it and a little gif too! Like I said i'm pretty sure i'm being a bit of a muppet and missing something!
https://pastebin.com/Y79UeHu6

[trim heart]

It can't be that, it's happening when I press the jump button, and is happening on the second frame of the jump animation

[leaden ice]

it's absolutely that

it's abundantly clear from your video

You have an error happening when you press the jump button

[trim heart]

So how could I fix it?

[leaden ice]

read the error

fix the error

[trim heart]

let me check

What does "receiver" means?

[leaden ice]

a receiver is a script or object that will execute the animation event

basically it's just saying you have an animation event set up, but no script or function to run the event

you either need to:

• delete the animation event if you don't need it
• create a receiver script and/or method for it

[trim heart]

I'm using visual scripting

[leaden ice]

irrelevant

you still need receivers for your animation events

Did you create the animation event on purpose?

[trim heart]

This is the jump animation:

[leaden ice]

that's not an animation

that's code that triggers an animation

[trim heart]

That's the code

[leaden ice]

and it's not relevant

[leaden ice]

^^

https://docs.unity3d.com/Manual/script-AnimationWindowEvent.html

Do you know what an animation event is? If not, read this^

You probably created an animation event by accident if you aren't sure what they are

[trim heart]

I know them, but why I need one? It was working fine until yesterday

[leaden ice]

in which case you can safely just delete it

[leaden ice]

You tell me, why did you create an animation event if you don't need it?

[trim heart]

Let me se if there is one

[leaden ice]

there is one

[trim heart]

Well, weird, there was an empty one

[leaden ice]

YEp you probably created it by accident

[high violet]

is there someone who have implemented self play using mlagent toolkit of unity?

[leaden ice]

#🤖┃ai-navigation would be the best place to ask

[trim heart]

Thanks

There's another thing, now when the attack animation ends, the jump animation is being set because the grounded variable is being activated, but I don't know why

[polar marten]

this looks nice

[stuck glacier]

Sort of a general question rather than a specific one, but, is VR game development really that much harder than normal game dev? Like if you're competent making flatscreen games, would starting a VR project be VERY difficult, or would it not be that much harder?

[polar marten]

what are you trying to do?

[mighty ivy]

Hi, I created a script that uses a NavMeshSurface. It's exposed in the inspector. After updating unity, it seems like I can't reference anymore a NavMeshSurface component to the NavMeshSurface public object in the script! Any clue why?

[leaden ice]

VR isn't any harder afaik, other than just dealing with the XR APIs and having to make your canvases in world space, and having tighter framerate requirements

[mighty ivy]

That's my script

[leaden ice]

I can't reference anymore a NavMeshSurface component to the NavMeshSurface public object in the script
Wdym by this?

[mighty ivy]

That's the navmeshsurface (above) and below there's the empty reference to a NavMeshSurface script

I can't drag-n-drop the NavMeshSurface into that

and I have absolutely no clue why

[sturdy venture]

I've actually just managed to fix it, I getting my maths bacwards. Basically im recreating RaycastHit.textureCoord but for a texture 3D instead of 2D

[mighty ivy]

it's like they are two different scripts

[hexed pecan]

Did you get the navmesh related errors to go away?

I think you have two navmesh packages conflicting

[stuck glacier]

Aight that's a relief lol

[leaden ice]

Should be able to. To be clear you're doing this with your mouse, yes?

assuming you have no compile errors etc

[mighty ivy]

y-yeah ahahaha

as everything

it's not a new project, it's been months since I'm working into this, and unless I'm being as stupid as I know I am that's not a beginner problem

[polar marten]

the things you think are decoupled are actually strongly coupled. everything should take place in the same function.

there might be a delay in execution between the main script and the hitbox object.
this is a nuanced concern, because there are only very specific circumstances where moving something in frame t can possibly result in a collision / trigger callback executing in frame t. the callback almost always gets called in frame t+1. this is the origin of many people using raycasts to do physics in the same frame, although if they mastered playerloops they wouldn't have to do that

[mighty ivy]

I also get that, and it doesn't give a NullReferenceException when it gets there, so I don't get how that's not working

[polar marten]

okay, usually you use an SDF for this

[leaden ice]

do you have OnValidate code?

What happens when you drag and drop do you get a red X? Or it drops but then still says None

[polar marten]

i assume that's what you mean by a texture3d

[sturdy venture]

https://docs.unity3d.com/ScriptReference/Texture3D.html with a raymarching shader to display them in camera, I did look at SDF approach too however I couldn't find much material on a way to possibly do it

[mighty ivy]

that's what happens

[leaden ice]

this is a hint

basically it seems like you have more than one definition of NavMeshSurface in your project somehow

Do you have a NavMesh package in your assets folder or something

Also check your package manager - make sure all packages are up to date etc, then delete your library folder and let it get regenerated.

[mighty ivy]

In the same gameobject?

[mighty ivy]

yes

in the assets

I uninstalled it fromt he package manager and manually installed it drag and dropping the directory into my asset folder

that's because it was giving me some errors when I upgraded unity

so... I need to reinstall it via package manager because it is conflicting?

[leaden ice]

remove the assets one

install from package manager

[polar marten]

you can look at how clayxels / mudbun does it

[mighty ivy]

I can't find anymore the link and I have no clue why

https://github.com/Unity-Technologies/NavMeshComponents/tree/master

also the official github page says "drop the files in the assets folder"

[leaden ice]

don't use the github thing

install it from the package manager

[trim heart]

I have a question, does the navmesh works in 2D?

[sturdy venture]

I'll check them out, I think i remember looking at mudbun as it meshes where as we keep everything in camera no meshes generated!

[leaden ice]

no

[mighty ivy]

use A*path

[leaden ice]

There's this though
https://github.com/h8man/NavMeshPlus

[polar marten]

hmm...

what is your objective? what is this application?

it meshes where as we keep everything in camera no meshes generated!
there is a lot to unpack here which concerns me

[sturdy venture]

Just some messing around in freetime with some very large geological data sets and visualising them, its basically all finished now though!

[trim heart]

I saw that it handle 2D, it's good on it?

[polar marten]

its basically all finished now though!
hmm...

you're near the beginning or middle of this long journey

[mighty ivy]

yeah, I used that ages ago and it worked well, but it's not super easy

[polar marten]

it meshes where as we keep everything in camera no meshes generated!
@sturdy venture for example. the only thing the GPU draws is meshes. so there's no such thing as "in camera no meshes generated." and maybe you mean Mesh, but that still doesn't make sense. you can, or cannot have, a Mesh, and some Meshes are "free" and some are costly. in the micro sense, i think you might misunderstand a lot about mudbun. in the macro sense, it performs extremely well, and isn't that what you care about?

but what is your objective? the texture3d, what is it?

the video you showed looks like you're clicking at a point cloud of an egg

lol

[trim heart]

Thanks

[sturdy venture]

Lol happy to message privately so not to clutter up here, the egg was just a very small sample data as it loads up instantly

[polar marten]

VFX graph also accepts a texture3d directly

[mighty ivy]

seems like it worked, thanks

[polar marten]

and can render SDFs for you

mudbun has an SDF based picker

in later versions of unity, you can directly render volumes

[polar marten]

loads up instantly
hmm

so it sounds like by " its basically all finished now though!" you mean "i am only just getting started"

what is the objective? to render tomographic SAR?

or some part of a photogrammetry pipeline?

anyway if you can express what it is, succinctly, for real, then maybe i can suggest the existing unity features that do this stuff

based on the code you are pretty new to unity and C#

@sturdy venture

we keep everything in camera
this concerns me specifically because it means you might be trying to author a shader

or maybe you wrote some kind of graphics code to render this volume, maybe in plain C# or something

and all this stuff already exists

[sturdy venture]

It's a volume renderer written in HLSL not C# don't worry 😅 The question I posted was me quickly prototyping a feature I had in mind to add, the egg is just an array generated in code to act as random sample data for me to use too vs importing a 15gb+ point cloud file for the system to render

[polar marten]

but why write a volume renderer

they already exist, lots of them

what is the idea?

there are at least 2 inside unity

[sturdy venture]

Because none of them did what I needed to do exactly and are limited to Texture3D's 2048 x 2048 x 2048 limit

[polar marten]

why do you think it's limited?

they definitely do what you need to do

you don't know 100% what you need to do yet

and there are already tools that do things like picking

the bigger picture question is why do this in unity? what is the goal?

what is this?

[sturdy venture]

Unity has a fair bit of the foundational work required and like I said its just a personal project to extend my own knowledge, I explored existing tools and use some but also wanted to develop some myself to understand the mechanics behind it

[polar marten]

then who's we? what 16GB data file is this?

it's not sensitive

in a micro sense, it sounds like you are at the beginning of understanding how to do this. in a macro sense, surely people have tried rendering large volumes, even in real time

the limit you are talking about isn't meaningful is the punchline, at a micro sense

and besides, why wouldn't it be preprocessed?

that's why i am asking what the application is

you will not need to modify this volume data in real time

and if you do, well, you gotta say what the application is

if you look into vdb, you'd see that there's mipmapping as a preprocessing step, and also volume aggregation as a strategy that pre-existing things use

[left sable]

re: everything should take place in the same function. How would you do that when using a separate hitbox gameobject? Currently the hitbox collider is a child gameobject of the primary gameobject which is made active when the entity attacks, and fed data for that specific attack to determine damage etc. OnTriggerEnter is used in the script attached to the hitbox. AFAIK there's no way to use OnTriggerEnter from a different gameobject but I may be wrong.

There's a lot packed into your statement so I'm interested in what a better way would be that would be more strongly decoupled.

I like to have custom shaped hitboxes over raycasts, similar to fighting games where large or small hitboxes are part of the advantages or disadvantages of certain attacks

[polar marten]

to extend my own knowledge
anyway, this is the knowledge.

right now it sounds like you are doing something for an architectural firm

or in an academic context

very very hard to say

[late lion]

While doctor finishes his rant, I spotted your issue:

Vector3 rayDirection = transform.InverseTransformPoint(camToVert);

That should be InverseTransformDirection.

[polar marten]

would be that would be more strongly decoupled.
you can't do this decoupled

[sturdy venture]

Haha Thankyou, I've actually just rewritten it to remove to remove the needless conversions all together: ``` //Camera to Box ray direction
Vector3 rayDirection = ( hit.point - Camera.main.transform.position).normalized;
Vector3 samplePosition = hit.point;

            var depth = tex.data.depth;
            var width = tex.data.width;
            var height = tex.data.height;
            var stp = 1.0f / depth;
            
            //raycasting till the depth
            for (var i = 0; i < depth; i++)
            {
            //making sample position range from 0 to 1
            var finalPos = transform.InverseTransformPoint(samplePosition) + offset;
            
            //changing coordinate based on resolution of 3D texture
            var scaledCoordinate = new Vector3(finalPos.x * width, finalPos.y * height, finalPos.z * depth);
            
            //Retriving pixel color based on current coordinate
            var c = tex.data.GetPixel((int)scaledCoordinate.x, (int)scaledCoordinate.y, (int)scaledCoordinate.z);
            
                    //if mouse hits certain valid surface inside volume(expect 0 alpha and certain color provided by user)
                    if ( c.r > Math.Max(tex.valueRangeMin, tex.cutValueRangeMin) && c.r < Math.Min(tex.valueRangeMax, tex.cutValueRangeMax))
                    {
                        var worldHitPosition = samplePosition;
                        break;
                      
                    }
                    //Next step,we movin
                    samplePosition += rayDirection * stp;
                    
            }```

[polar marten]

How would you do that when using a separate hitbox gameobject?
there are lots of ways to do this.
AFAIK there's no way to use OnTriggerEnter from a different gameobject but I may be wrong.
sure, not literally that way

it's tough. there is a lot between here and there. you are limited by how expressive you can be in terms of the rules you are trying to do

you also have to look carefully at the unity execution order documentation page

to help you understand what is going on

in terms of timing

[reef compass]

Hello, I need help,

I exported my 2D game and there is very bad Quality, How can I fix it?

Text is Too bad

[weak flame]

set number under 0 to -1 and above 0 to 1. How to do?

[west lotus]

if(num < 0) { num= -1} else{ num = 1}

[weak flame]

isn't there a function in mathf for that, I remember there is but I dont remember the name

[sturdy venture]

Could be thinking of Mathf.Sign ?https://docs.unity3d.com/ScriptReference/Mathf.Sign.html

[weak flame]

yes

thank you

how can I detect if a button is not pressed using unity new input system?

[west lotus]

If its not pressed ?

[weak flame]

yes

?

[granite nimbus]

https://hatebin.com/opkfmmvzqk
how do I define NativeArray like this? can't figure out. Do I really have to just loop through each index?

[sturdy venture]

IIRC you can use the NativeArrayUnsafeUtility to copy a buffer over: https://docs.unity3d.com/ScriptReference/Unity.Collections.LowLevel.Unsafe.NativeArrayUnsafeUtility.html

[west lotus]

Should be able to get it to work with this https://docs.unity3d.com/Packages/com.unity.inputsystem@1.5/api/UnityEngine.InputSystem.Controls.ButtonControl.html#UnityEngine_InputSystem_Controls_ButtonControl_wasPressedThisFrame

I think havent touched the input system in a while

[weak flame]

but I want to check if it is not pressed, not just this frame

[soft shard]

What exactly are you building where you need to know if a key is not pressed at all?

[granite nimbus]

doesn't it do same thing as this https://docs.unity3d.com/ScriptReference/Unity.Collections.NativeArray_1-ctor.html#:~:text=public NativeArray<T0>(T[] array%2C Unity.Collections.Allocator allocator)%3B
? anyway I'd like to predefine it, without doing any crap runtime

[west lotus]

Yes Im pretty sure you can feed a regular array into the constructor of a native one

[weak flame]

I want to make a deceleration system for the player

[granite nimbus]

which, again, isn't same as just hardcoding an array like I showed. I wan't to be able to hardcode it

[weak flame]

and for that, I need to check that the player isn't clicking any of the movement buttons(which I read the value from using InputValue)

[west lotus]

Hardcode your byte array feed it into a native one

[granite nimbus]

I just wanted to know if there is a way to hardcode NativeArray itself

but it seems like no

[soft shard]

So you could check if the value your reading is 0, or there is also .IsPressed which is similar to a continuous GetKey check, though the "new" input system is best used as events rather than used in Update, so it may make more sense to use .started and .cancelled or as Uri suggested, WasPressedThisFrame and WasReleasedThisFrame, since if it was pressed, you know the key is still down, and if it was released, you know it no longer is

[hexed pecan]

Can't you just check isPressed?

Or if you already have cached values, use those

[weak flame]

its gives me an error...

[hexed pecan]

What's your code and what's the error

[weak flame]

void OnMove(InputValue input){
pressed = input.isPressed;
}

[solemn raven]

hi,
is it possible to call "add Open Scenes" from a script?

[west lotus]

Not that I know of. Why do you need it ?

[leaden ice]

https://docs.unity3d.com/ScriptReference/Unity.Collections.NativeArray_1.CopyFrom.html

[hexed pecan]

And whats the error?

[weak flame]

void OnMove(InputValue input)
{
  pressed = input.isPressed;
  //get the the x axis for the vector2.
  movX = input.Get<Vector2>().x;
  //turn the movX variable into int and then assign that into the variable facing.
  facing = (int) movX;
}

InvalidOperationException: Cannot read value of type 'Single' from composite 'UnityEngine.InputSystem.Composites.Vector2Composite' bound to action 'Player/Move[/Keyboard/a,/Keyboard/d]' (composite is a 'Int32' with value type 'Vector2')

[hexed pecan]

Not sure how that error is related to the code you showed... But you should ask in #🖱️┃input-system Unless if someone here knows

[leaden ice]

You can't directly use a collection initializer because NativeArray doesn't satisfy the the requirements for a collection initializer.

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/object-and-collection-initializers#collection-initializers

[weak flame]

I added the reset of the code in that function if that helps...

[leaden ice]

Look at GoUp

One of these things is not like the others

[hexed pecan]

Yeah, you added the line that actually causes the error as far as I can tell:cs movX = input.Get<Vector2>().x;

[weak flame]

can you tell why?

because before I added the

  pressed = input.isPressed;
``` it all worked

[hexed pecan]

Looks like your axis is not the type you are trying to read it as

[weak flame]

.

it did work before

[leaden ice]

You can't do isPressed on a vector2 action

Doesn't make sense

[weak flame]

why?

[leaden ice]

How do you press a joystick

[weak flame]

ha

so on vector3 you can...

?

[leaden ice]

No...

What are you trying to do with isPressed?

What are you trying to detect with that

[weak flame]

try to check if the player is not pressing a button and run a function if it is true.

[leaden ice]

What button

If it's a separate button you need a separate input action

[weak flame]

its like a group of buttons

[leaden ice]

Read the vector2

Check if its magnitude is 0

[leaden ice]

Vector2 vec = input.Get<Vector2>();
pressed= vec.magnitude < 0.1f;``` for example

Is this a 2D composite or just a regular axis

If 2D then this^.

If regular axis then float

[hexed pecan]

Composite according to the error here^ right?

[leaden ice]

From the screenshot seems it's a 1D axis

[weak flame]

yea

but I still need the second axis (for jump)

[leaden ice]

That should be a separate action

Show your action configuration for Move

[weak flame]

just realized that jump is in another action

[leaden ice]

it shouldn't be a 2D vectotr

[weak flame]

so what should it be?

[leaden ice]

The action should be Action Type: Axis

then a 1D axis composite binding

You only use Vector2 and 2D composites for two dimensional inputs

[weak flame]

ho didn't know about this, I'm gonna try that

[leaden ice]

and then the code should just be:

movX = input.Get<float>();
pressed = movX != 0;```

[tired forum]

So I have an airship that I am using physics to move (so that I can have a little more of a floaty feeling). What is the best practice for handling the fact that I can't have a mesh collider w/ a rigidbody and Kinematics ?

Should I do it using a second physics scene .. do all the forces over there then translate position movements to the first scene? Or should I go with a compound mesh?

[heavy hornet]

I already have some movement in my 3d game, but I want to make it multiplayer... should I just start with a new Project or is there some "easy" way to make it multiplayer? (I tried making it multiplayer, but it didn't really work properly)

Could also look into Asset Pipeline topics to speed up workflows if you're interested in that kind of stuff. Custom asset importers, asset types, post processing, etc. https://docs.unity3d.com/Manual/AssetWorkflow.html

[light wraith]

is there a difference between rigidbody.moveRotation() and transform.Rotate()?

[leaden ice]

yes

[light wraith]

ohhh moveRotation rotates to a rotation and Rotate() rotates the entire object?

[leaden ice]

well yes

but

that's only oone part of it

MoveRotation cues up for the Rigidbody to be rotated in the physics engine during the next physics simulation step. If it's kinematic it will realistically push objects out of the way.

transform.Rotate() immediately rotates the object directly, without any regard for the physics simulation

[light wraith]

Interesting, is there any MoveRotation alternative to characterController or transform?

kind of a dumb questions since it depends on the physics, I can probably just rotate on fixedUpdate

[swift falcon]

Does anyone have any experience using a neo4j database with unity?

[zinc merlin]

guys what's the current best dependency injection library for Unity? I've heard of Zenject/Extenject but it's no longer maintained so I'm not comfortable to start a new project with it.

[cold parrot]

whats best depends on your needs, also extenject is not abandoned its just complete/finished. If you want something thats a bit more opinionated than zenject and allows you to do fewer stupid things, try VContainer

[zinc merlin]

I'll take a look at it, thank you

[urban gust]

Hey guys im starting to look at Architecture for Unity and trying to make the code clean, i'm searching for Interfaces, Inheritance and Script Composition, and i'm seeing that for example : Damageable(Composition) would be better than the IDamageable(Interface), because of not repeating code with interfaces. So basically want to know if i'm going the right way (?)

[violet field]

Hi, does anyone has the script to a 2D press jump (press longer for a longer jump) like Super Mario

[leaden ice]

Composition > interfaces/inheritance in Unity.

But your example is not composition

it's inheritance

I recommend making Damageable a completely separate component

[solemn raven]

hi ,
does anyone knows how LoadSceneAsync works ?? how does it use the "scene Name" to get the scene and load it ?

[leaden ice]

It picks a scene registered in build settings with that name

[solemn raven]

that is what I thought but looks like the scene in build settings doesnt have property name

EditorBuildSettings.scenes is an array of EditorBuildSettingsScene which u can get something called "guid" and "path" from

path is the file path

not sure what GUID is

[leaden ice]

this is not related to LoadScene though

this is editor stuff

what are you trying to do

[solemn raven]

im trying to add/modify scenes in EditorBuildSettings.scenes and also load them on the same script.

[leaden ice]

If you want to load scenes in the editor you should be using https://docs.unity3d.com/ScriptReference/SceneManagement.EditorSceneManager.OpenScene.html

[solemn raven]

is the scene's file name is exactly the "scene name" ?

[solemn raven]

thanks but not quite, i need to load scene on monobehaviour script , but add scenes on the editor

what is the scene name ?
example if we have " Assets/Scene2.unity " does that mean the scene name ="Scene2" ?

[leaden ice]

yes

[solemn raven]

I could cut that from the path if that is the only way around

[solemn raven]

Thanks 🙂

hey,
what do i need to include to use "Path"(using ....) ?
https://docs.unity3d.com/ScriptReference/Path.html

[stable rivet]

This is the standard library System.IO.Path class
that

[solemn raven]

Thanks 🙂

how did i miss that 😄 , thanks

[stable rivet]

I mean, it's alright - but the docs you yourself posted are literally 2 sentences long, and contain the answer 😄

[solemn raven]

it wasnt bold or anything , not my fault 😛

[jade nexus]

how do game developers make a game use a Newtonian physics system

[supple canopy]

I'm looking for a script that automatically creates an animation clip that swaps the material of an object's Skinned Mesh Renderer slot to a selected material.

Does anyone know how to do this, I'm new to c# coding, but kinda know how to read the code & have done a bit in python & java

[jaunty needle]

How would I go about creating an infinitely scalable grid like the one desmos has? I'm trying to recreate it but I'm stuck on that part.

[tawny mesa]

Hey, according to unity profiler "Destroy cull results" takes a lot of time in my game, what it is related to? And how to optimilize it?

[neon plank]

Why point is (0, 0, 0) but there is a collider (i.e: there was a hit)? 🤔
I'm using Physics.CapsuleCastNonAlloc and it returned an integer greater than 0, so the first hit should have some point.

[zinc parrot]

If I have a script that has "using UnityEngine.Rendering.HighDefinition;"
how do I make it so that this doesnt cause errors if im not in HDRP without commenting it out or anything manually?

[neon plank]

Maybe using a preprocessor directive? Not sure if there is one for HDRP

[late lion]

Check if HDRP has a define symbol it adds. If it doesn't, you will have to create an editor script that detects HDRP and adds your own define symbol.

[zinc parrot]

it would need to be like a #define kind of thing yeah...
I just want to be able to include this file in my project, but not have it throw errors if its not in HDRP

[leaden ice]

0,0,0 is where the hit happened perhaps

[somber nacelle]

https://forum.unity.com/threads/hdrp-lwrp-detection-from-editor-script.540642/

[zinc parrot]

lookin at that right now but it needse to stop the entire file from compiling

[neon plank]

The collider is very far away from that point and is not so large, so this is unlikely

[somber nacelle]

wrap anything in that file that depends on HDRP in a preprocessor directive. then use the suggestions in that thread i linked to define the symbol if hdrp is present

[zinc parrot]

alright! thanks! I will try that!

[uncut tundra]

Why is unity giving this error Assets\Scripts\Weapon.cs(98,3): error CS0246: The type or namespace name 'IEnumerator' could not be found (are you missing a using directive or an assembly reference?)

are you missing a using directive

[faint scroll]

how do i translate a vector relative to another vector like this? (increasing the distance, but not the angle)

[stable rivet]

Did you copy this script from somewhere?

It's not a bad thing if you did. I'm just always curious as to how people get these errors. As soon as I start typing "IE", if it's not autofilling, I already know something's wrong.

[leaden ice]

Ray r = new Ray(A, B - A);
Vector3 result = r.GetPoint(someDistance);```

[faint scroll]

is the order of points essential?

[leaden ice]

yes

[faint scroll]

so the location of these points matter?

i dont know how to explain

like in a 2-1 != 1-2 kind of matter

ok i solved it

thx

[leaden ice]

no the order of the points in the code matters

the location doesn't matter

[solemn raven]

Hey,
if I want to attach a reference to a Scene file in a class "scene.unity" how do i do that ?
like for example string type references can be stored by something like this public string txt

GameObject ?

Scene?

[leaden ice]

you can't really do it

it's been discussed to death

the best ways are all hacks around basically just storing a string

there's no drag and drop scene references

[solemn raven]

ok but how do build settings does it ?

[leaden ice]

I don't have access to Unity's source code

[solemn raven]

is there is a way around through the editor maybe , that is what iam thinking

[faint scroll]

how do i randomize the location of C to the left/right from B where the location should lay on the perpendicular line of AB?

[leaden ice]

Vector3 aToB = (B - A).normalized;
Vector3 offsetDir = Quaternion.Euler(0, 0, 90) * aToB;
Vector3 result = B = (offsetDir * Random.Range(-maxDistance, maxDistance));```

something like this

assuming we're looking at the x/y plane in the image

[faint scroll]

hm i have another problem

i suck at maths lol D:

i get B by getting Camera.main.ScreenToWorldPoint(Input.mousePosition)
but it should always be the same distance from A, because i use a line renderer to connect them, but i dont get it to work

i tried (Camera.main.ScreenToWorldPoint(Input.mousePosition) - A).normalized; but it didnt work

[leaden ice]

define "didn't work"

show your code

explain what you expect to happen

and show what is happening instead

[faint scroll]

it gave wrong results, wait

[leaden ice]

Camera.main.ScreenToWorldPoint(Input.mousePosition) is going to give a point with the wrong z coordinate usually btw

you need to either give it a depth or set the Z of the result

[faint scroll]

yes i handled that

BlaBla-new Vector3(0, 0, Camera.main.ScreenToWorldPoint(Input.mousePosition).z)

[grizzled needle]

Is there any way that I can shorten this?

    _level.time = parameters.levelTime;
else
    Debug.LogError("RunParameters.levelTime is null, cannot set parameter");```

[leaden ice]

it's pretty short already...

[grizzled needle]

I have 8 other variables and counting that I need to set like this, so I'm looking to see if there's a better way already

if not, then 🤷‍♀️ i'll just go ahead and copy and paste lol

[leaden ice]

parameters.Set(ref _level, ref .... etc)```

or put them in a collection

and use a loop

[grizzled needle]

great idea, i didnt think of using the ref keyword!

[faint scroll]

so point A is transform.position
B is Camera.main.Screen....

i want to draw a line from A going to B with a fixed length.

because as of right now, it draws from A to B, which later outputs wrong results when messing with the line

[leaden ice]

A to B is B - A

[leaden ice]

also I don't understand what this is supposed to do

What do you do with BlaBla

[faint scroll]

eliminate z issue

[leaden ice]

but you're now using a position with x and y as 0?

[faint scroll]

(Camera.main.ScreenToWorldPoint(Input.mousePosition) + new Vector3(0,0, Camera.main.ScreenToWorldPoint(Input.mousePosition).z * -1)

[leaden ice]

🤔

[faint scroll]

oh wait

[leaden ice]

why not just:

Vector3 point = Camera.main.ScreenToWorldPoint(Input.mousePosition);
point.z = 0;```

faster, clearer, definitely correct.

[faint scroll]

i just realised this too xD

[faint scroll]

so what should i do?

[leaden ice]

#archived-code-general message

[faint scroll]

Vector3 Cam = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Cam.z = 0;
Vector3 end = (Cam - transform.position);
CreateLine(/*color*/Color.red, /*width*/0.05f, /*start*/transform.position, /*end*/end, /*lifetime*/20);

[leaden ice]

what does CreateLine do

[faint scroll]

set up a lineRenderer

that code works fine

[leaden ice]

Vector3 end = (Cam - transform.position); is getting the direction from A to B

not the position of B

If you want start and end that's just transform.position and Cam

[faint scroll]

yes, thats why i asked what i should do

[leaden ice]

wdym

CreateLine(/*color*/Color.red, /*width*/0.05f, /*start*/transform.position, /*end*/Cam, /*lifetime*/20);```

Pass in start and end, as your comments imply^

[faint scroll]

i want to return a point with a fixed distance to a, no matter where ypo click but still on the line between A and the Clicked Coordinates

[tepid river]

normalize and multiply with distance

[faint scroll]

and add A?

[surreal garden]

For some reason my game screen is not visible and my scale is unknown

[faint scroll]

saw this on SO:

var distance = dist;
var direction = (hit.point - startPos).normalized;
endPos = startPos + direction * distance;

[surreal garden]

This suddenly happened

[faint scroll]

well it does work now, but only if the initial distance is above the wanted distance.

[leaden ice]

The code I shared you way back when you assked the question will do that

[faint scroll]

read message above yours

[leaden ice]

you'd have to show your code

#archived-code-general message this is what I suggest

[faint scroll]

same issue like i said

works only if the initial distance is above the wanted distance

[leaden ice]

it should work no matter what

[surreal garden]

anyone?

[leaden ice]

https://dotnetfiddle.net/CPIvqk

It works for any distance

[leaden ice]

what am I looking at here?

[leaden ice]

this looks like you're not properly zeroing out the z axis

so it's going into or out of the screen

or your origin point is not at z = 0

[faint scroll]

A is the red square (start)
B is the end of the line (mouse position)
If i draw the lines, it works fine as long as my mouse position doesnt go below a certain value

[leaden ice]

show the object positions

[faint scroll]

ooo

z position seems to be off w8

approved

it works finally

thank you very much

if(string.IsNullOrEmpty(txt)) return "someResponse";
else return null;

correct ?

[leaden ice]

you have the if and else backwards

it's truevalue : falsevalue

[solemn raven]

ohh, thanks a lot ❤️

[faint brook]

what would be the most efficient way of getting all the game objects with a tag under a certain parent?

so far i just check every object with the tag and then see if its parent is the watned one but i fear down the line this will cuase preformance issues

[leaden ice]

Why not just create them under the desired parent in the first place

Hey, is anyone else having errors happen when the inspector is in Debug mode? I am using unity 2022.2.0b16 and trying to debug a UI button not being able to be hovered over(aka background image not changing color) after being clicked once, but the inspector is freaking out, and tons of InvalidOperationException: The operation is not possible when moved past all properties (Next returned false) errors.

[leaden ice]

This person maybe?
#💻┃unity-talk message

[leaden ice]

you should update unity btw

you're on an old beta version

there's 2022.2.10 (non beta)

[fluid lily]

Yeah gonna try that first

It has been solid so far so haven't needed to update

At least it definitely seems to be an editor error and not my code, so will do a bug report if this doesn't fix it. Though those take months in my experience to go anywhere 😭

Those this button bug is driving me crazy. If I select out of the player and back in the button works fine again.

[tall lagoon]

hey guys Im trying to make 2D Building system for my game and im trying to make it grid based so things snapso should i use the grid that unity uses like a gameobject with a grid compoenent or should i code the grid fromscratch??
Also how would i get things to snap to the grid?

[copper shoal]

nvm, misunderstood the question

[tall lagoon]

ok

ill be here for your suggestions

[copper shoal]

maybe something like this, but in 2D?

[tall lagoon]

ok thanks

ima check it out

[copper shoal]

I'm trying to make a script that gives my player some velocity in the opposite direction of the spikes he touches ( so they bounce off the spikes). My spikes are on a tilemap and use tilemap collider + composite collider. When I try to use Collider.GetContact(0).point, Unity doesn't really likes that and for some reason it places the point of connection somewhere in the space. How else can I make a script like this?

This was supposed to be a Debug.DrawLine between the player collider and the spike collider.

[leaden ice]

You'd have to show your code

[copper shoal]

        {
            Vector2 direction = (new Vector2 (transform.position.x, transform.position.y) - collision.Getcontact(0).point);
            Debug.DrawLine(transform.position, direction);
            rb.velocity = direction * TrapKnockback;
        }
```]

[leaden ice]

Also the spike collider is the overall Tilemap collider

[faint brook]

I do. I am trying to get a list of all enemies in a room (they are children of the room they are in)

[leaden ice]

You're passing a direction vector into draw line

Why?

It needs two positions

Not a position and a direction

[copper shoal]

I'll fix it

[leaden ice]

Also the contact has a normal

You don't need to calculate anything with positions

You should use the contact normal

[copper shoal]

Okay, it shows correctly now

[copper shoal]

wdym?

collision.contacts[0].normal?

[leaden ice]

Also it's more efficient to do collision.GetContact(0)

it doesn't have to copy the whole array that way

[copper shoal]

so should I use collision.contacts[0].normal or collision.GetContact(0)?

[leaden ice]

collision.GetContact(0) replaces collision.contacts[0]

[copper shoal]

👍 thanks, it's working now

[cerulean mist]

anyone know how I can align a particle sub emitter normal with the normal of a collided object

[steady thicket]

If anyone has any suggestions of data structures that could be good for the "Open Set" of an A* pathfinding algorithm I would really appreciate suggestions. I've been trying a lot of things and so far the best thing I have found is my implementation of a Skip List. Also, if anyone knows anything about Skip Lists I would love feedback about my implementation as I didn't know anything about them before today lol.

Here is my current Skip List implementation: https://paste.ofcode.org/wT3X8ykCDeHEFstP3cEyPW

What is better use a audio clip on audiosource component or use AudioSource.PlayClipAtPoint ?

[potent sleet]

In what context ?

Why not PlayOneShot

[hexed pecan]

Avoid PlayClipAtPoint when possible because it instantiates a temporary gameobject and destroys it after the clip is over

This is kinda expensive just for playing a sound

What are backquotes

[deft pike]

hey everyone, does anyone have an idea on how to check if the player is following us on social media ? (in order to give them an achievement for each social). Do I need the user to login to each social to check that ? is there a easier way of doing so ?

[dim spindle]

no\

[velvet quartz]

so what do

[velvet quartz]

bc i do 3D sounds

and PlayOneShot need audiosource component

[hexed pecan]

Hm? Use an existing audiosource if possible

[velvet quartz]

So i need to put a audio source on all character

[hexed pecan]

Why not?

You can also make your own audio manager that pools audiosources

Or use some audio middleware like FMOD/WWise but that's different

[solemn raven]

is it possible to serialize public data as readonly in the inspector only ?

like i wanna be able to modify a string from another script public string txt
but I dont want it to be available for me to modify the value of txt from the editor, just read it , is that possible ?

readonly blocks the other script from modifying the variable ... so it doesnt work in this case.

[serene lake]

I need to use 2d pathfinding in my game, is there any way to do it without the asset store or simulating it somewhere else?

[mystic ferry]

creating your own algorithm, although there’s no real point unless you want the practice

[serene lake]

I just didn't want to purchase a $30 package for something small

[mystic ferry]

iirc there are several A* packages for free

[serene lake]

Also I have more complex shapes than cubes and capsules for navmesh

How would I get those to work?

[mystic ferry]

depends on what package you’re using, tinker around with whatever you find, it’s likely quicker than writing one from scratch

thanks a lot 🙂
i moved on and now im in a bit bigger problem 😄

im trying to add items that i have on a list<> to an array

[dusk apex]

Maybe consider using Lists instead of arrays if the size of the collection needs to change often.

[solemn raven]

is it possible to add items on a list to an array ?
as far as i know array can only be defined in the following way

array = [list[0],list[1]....];

but I dont know how many items on the list

[solemn raven]

unfortunately, it has to be an array, it's a part of an api that i dont have opensource for

[dusk apex]

int[] iArray = new int[iList.Count];```

[dusk apex]

Pick a size large enough for all possibilities.

[quartz folio]

iList.ToArray() will create a new array from a list

but it will have to allocate it

[solemn raven]

remember i have to modify an api's array , so i could convert my own list however i like but i need to define the api's array to that value
can i just do that ?
iArray = iList.ToArray() ?

[quartz folio]

I have no idea what the API looks like

[solemn raven]

if that is all i need to do I love it 😄

[solemn raven]

just an array of a custom class but we could useint as an example

[dusk apex]

ToArray would return you a copy of the List. If you're wanting a copy of it, that'd be what ToArray does.

[carmine pine]

why cant i move the gameobject?

[quartz folio]

Because you've frozen the object.

[carmine pine]

im trying to fix it but this means not equal to right?

or is it -=

[quartz folio]

Sure, but that's not assignment if that's what you're trying to do

[carmine pine]

ik

[solemn raven]

Thanks ❤️

[solemn raven]

Thanks ❤️

[carmine pine]

is this correct?

[dusk apex]

If you just want to stop when you aren't pressing anything.. try: cs myRigidbody.velocity = Vector2.up * speed * Input.GetKey(KeyCode.W) ? 1f : 0f;

[quartz folio]

What you have added is pointless

[carmine pine]

why doesnt it work?

[quartz folio]

Because you never unfreeze the object.

[carmine pine]

oh you need to unfreeze it?

[quartz folio]

Of course

[carmine pine]

my b

how do i do that

[quartz folio]

Look through RigidbodyConstraints2D and apply the obvious one

[carmine pine]

how do i assign not equal?

[quartz folio]

You don't. You assign what you intend to assign

[carmine pine]

i did it

[mystic ferry]

oh my god

[carmine pine]

idk how to optimize it

and i dont care

also its not working how i wanted to and now im sad

[dusk apex]

What're you trying to do?

[boreal condor]

I have a question, I want to modify an Animator State Machine's motion, is there a way to do this? All the information i've found is outdated or the code doesn't work as it was found, there are new APIs it seems but documentation links are dead apparently...
This is the field I'm trying to modify

[leaden ice]

Like 40% of this code doesn't do anything

[quartz folio]

any time you set .constraints it sets the value completely.
If you want to combine two things use |
Like .constraints = RigidbodyConstraints2D.FreezePositionX | RigidbodyConstraints2D.FreezeRotation;

this is also completely redundant as it's covered by the fact it's an else to those two conditions

[wispy wolf]

I have a rigidbody that eventually collides with a simple sphere collider. If this hit normal points a certain direction I want this rigidbody to stop moving. This is easy enough. But if the normal is a different value I want to add an impulse to repel it while maintaining its momentum. The problem I have is that once the rigidbody's collider hits the sphere it stops, so in the case of the added impulse all the existing momentum is gone.

[leaden ice]

use a trigger collider instead and just use the opposite of the rigidbody's velocity instead of the hit normal to do your direction calculations

[solemn raven]

hey, Im facing an odd problem
I think list get corrupted after deleting an item of it on the editor (inspector)

I have a custom class the holds info of the scene objects , its NAME , COunt in the scene and GUID

once i delete one of the items from the list on the inspector and try to load it again the list get corrupted
i looped through it , the name is correct , the count is correct but the GUID of all item became " 0000000000000000000000000" what is going on ?

I think I ran into a bug this time...

unity 2021.3.5f1

i debuged the list before and after modifying the list guid certainly goes to zero and also some references became NULL! , it wasnt null before

[solemn raven]

hey,
How to assign List<customClass> without it being a reference to the original List<customClass>?

i wanna try making a temp list and use it for reference instead

[prime sinew]

List<MyClass> originalList;
List<MyClass> copiedList = new List<MyClass>(originalList);

Heyo, I want to keep adding torque to an object every .1 seconds while a key is held down. Would a coroutine be best for this purpose?

Hi, I'm using the unity starter asset first person controller. I'm trying to add my own input into the starterassetsinput script, but it doesn't work the way I'm intending. I'm trying to have events fire once, but when I press the key, it fires for every frame the key is pressed. How would I change this

I already know about buttons and events

like started

and cancelled

[static crown]

Where would I place the code?

[inner relic]

but the thing is the unity first person controller doesn't use that, and I don't want to refactor the code
