[potent sleet]

not sure how this related to the previous code 😅

[pearl swallow]

It's just if its within a certain range, it can shoot the player.

[hexed pecan]

Side note, use ForceMode.Impulse instead of multiplying with some crazy number like 100

[potent sleet]

what is inRangeFire how's it related to movement though

[pearl swallow]

It isn't I'm just posting more bits of code, I'm just throwing things that could possibly cause weird stuff in the moving code.

[potent sleet]

you'd have to debug your if conditions make sure none of them are running together

[pearl swallow]

They aren't, I did that.

I did the debug.log and made different ones to make sure it wouldn't trigger. It just constantly moves regardless of state.

Would ResetPath() possibly work to stop it?

[potent sleet]

show code with the debugs

[pearl swallow]

        if (distanceFromPlayer >= 35)
        {
            spiderMesh.SetDestination(spiderMesh.transform.position);
            inRangeFire = false;
            Debug.Log("working");
        }

        else if(distanceFromPlayer<35 && distanceFromPlayer >= 20)
        {
            spiderMesh.SetDestination(player.position);
            inRangeFire = false;
            Debug.Log("Called");
        }

        else if(distanceFromPlayer <20 && distanceFromPlayer >= 15)
        {
            spiderMesh.SetDestination(player.position);
            transform.LookAt(new Vector3(player.position.x, transform.position.y, player.position.z));
            inRangeFire = true;
            Debug.Log("initiated");

        }

        else
        {
            spiderMesh.SetDestination(spiderMesh.transform.position);
            transform.LookAt(new Vector3(player.position.x, transform.position.y, player.position.z));
            inRangeFire = true;
            Debug.Log("Last");
        }

[vale karma]

Because no one saw my message on the the other channel so I waited a bit and posted it here

[pearl swallow]

I'm 70/30 that there's a rule against doing that.

[potent sleet]

ok well crossposting isn't allowed

#854851968446365696

[potent sleet]

which Debug is being called when is suposed to stop

[pearl swallow]

"Working" when it is outside the 35 unit radius and "Last" when it is too close.

So effectively the spider needs to be stopped when x>=35 or... when x<15

[potent sleet]

so it does run but does not stop even with Setting destination to itself ?

[pearl swallow]

Correct.

Well

It doesn't move the player

It kind of just... zigzags a bit on the ground

[potent sleet]

a dirty fix but you can try set agent speed to 0 when in those if conditions

normally setting destination to itself works for me .

[pearl swallow]

Okay... could using ResetPath() also be an option for stopping it?

[potent sleet]

you can try
isStopped = true
resetpath()

I never used it

[vale karma]

So when dose it not count as cross posting

[knotty sun]

when you remove your post from the original channel

[pearl swallow]

I'll try doing the speed thing.

Oh... I wonder if SetPath might work...

[potent sleet]

ok cool lmk if u fix it

[proud wedge]

Hey ya'll can I ask a question

[pearl swallow]

That's why this is here.

[proud wedge]

Aha, cool

So I have a script that controls the rotation of a turret

and I'm trying to get the state of the rotation from the turret, but whenever I use Transform.Rotation, it throws an error saying its not defined for Transform

How do I get that rotation?

[potent sleet]

transform.rotation

it's not captial R

[proud wedge]

ah

[potent sleet]

neither is Transform unless you're making a separate reference other than itself

[proud wedge]

Gotcha

So are lower cases typically only to refer to self?

[potent sleet]

nah it's just a special propriety unity made for certain classes

any monobehavior has transform prop because it always belongs on a gameObject

every gameObject has transform and vice versa

[pearl swallow]

Figured it out.

Well, I did a really stupid way of it, at least I think.

[south ferry]

Hey all ... I am trying to remember what is the name of this pattern:
Example: if (_lastDeviceUsed.displayName is "Mouse" or "Keyboard" or "")
Does anyone know? 🙂

[pearl swallow]

navmesh.isEnabled = true (or false).

[potent sleet]

you're disabling the whole navmesh just to stopp 1 agent

[pearl swallow]

Stopping the one agent.

[potent sleet]

I know but still seems overkill

something else is wrong

you shouldn't have to do that

[pearl swallow]

I renable it afterward.

It works fine.

if (distanceFromPlayer >= 35)
        {
            spiderMesh.enabled =false;
            inRangeFire = false;
            Debug.Log("working");
        }

        else if(distanceFromPlayer<35 && distanceFromPlayer >= 20)
        {
            spiderMesh.enabled =true;
            spiderMesh.SetDestination(player.position);
            inRangeFire = false;
            Debug.Log("Called");
        }

        else if(distanceFromPlayer <20 && distanceFromPlayer >= 15)
        {
            spiderMesh.enabled = true;
            spiderMesh.SetDestination(player.position);
            transform.LookAt(new Vector3(player.position.x, transform.position.y, player.position.z));
            inRangeFire = true;
            Debug.Log("initiated");

        }

        else
        {
            spiderMesh.enabled = false;
            transform.LookAt(new Vector3(player.position.x, transform.position.y, player.position.z));
            inRangeFire = true;
            Debug.Log("Last");
        }

[potent sleet]

Hey if it works, that's all it matters, But I would still look into why it had to be done

[pearl swallow]

I will.

[potent sleet]

did agent.Speed = 0 not work tho @pearl swallow

[pearl swallow]

No

It still moved.

[potent sleet]

yeah it's odd then something is overriding it

[pearl swallow]

Though I'm wondering if it may be because of the terrain not being flat?

But Navmesh isn't a collider.

[dusty hare]

Hey ... anyone know how to read vertex color in a C# script? I need to know the color of a specific vertex.

I already have a handle on the vert

as Vector3

[potent sleet]

nah , really this shouldn't be an issue . Something else is going on tbh

[pearl swallow]

Most likely

Idk, half the time I use Unity something is getting haunted.

[potent sleet]

you can debug things like NavMeshAgent.destination

to check were they were actually going

https://docs.unity3d.com/ScriptReference/AI.NavMeshAgent-destination.html

also things like hasPath etc.

[pearl swallow]

I'll tweak it later. I'm just happy it functions.

[limber fog]

ok so I have this code

    {
        Window.SetActive(false);
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    public void OnPointerClick(PointerEventData eventData)
    {
        if (Opener == true && Window.active == false)
        {
            Debug.Log("frund");
            compinfo.HowManyScreensUp++;
            Window.SetActive(true);
            Window.SendMessage("Loading");
        }
        else if (Opener == false && Window.active == true)
        {
            compinfo.HowManyScreensUp--;
            Window.SetActive(false);
        }

    }
}```

i put it on an object and duplicated the object three times.
it works for the first two objects, and yet...

[pearl swallow]

How do you have it be organized in opening up?

Is it an array or something?

[limber fog]

err, i just put the script on each rawimage and pluged whatever game object i want opened into window in the inspector

[pearl swallow]

Is the last one a button or something?

[limber fog]

nope, all three of them are rawimages

[pearl swallow]

And the 3rd one is connected properly?

[limber fog]

yup, in fact can switch out the game object I have in window and the first and second one will still activate whatever is in the window varible but the third still doesn't

[regal epoch]

when running my game, it suddenly freezes and i have to force close unity. I debugged myself into knowing where it freezes. There is this function i call on button click. The first time i call it, everything is fine and it does what its supposed to do. The second time tho it freezes the whole thing. In the script there are a few debug points. when it freezes, it doesn't even print the first one. so im guessing something is going wrong when i call the method?

    {
        Debug.Log("0");
        objectsToHide.SetActive(false);
        objectsToHideButtons.SetActive(true);

        Debug.Log("1");
        do
        {
            int rndNameIndex = Random.Range(0, names.Length);
        } while (rndNameIndex == previousRandomName);
        previousRandomName = rndNameIndex;
        Debug.Log("2");

        textDisplayName.GetComponent<Text>().text = names[rndNameIndex];
        Debug.Log("3");
    }```

[main token]

Hi, I have an assortment of points on the XY plane, and I would like to be able to draw a web between the points. Does anyone have any idea how to do this properly?

currently my code looks like this:

private void OnDrawGizmos() {
            List<GameObject> drawn = new List<GameObject>();
            
            for (int i = 0; i < _points.Count; i++) {
                for (int j = i + 1; j < _points.Count && !drawn.Contains(_points[j]); ++j) {
                    
                    Gizmos.DrawLine(_points[j].transform.position, _points[i].transform.position) ;
                    drawn.Add(_points[j]);
                }
                
            }
            
        }```

[heady iris]

So you want to connect nearby points together?

sounds like you need to make a maximally connected planar graph

to use a bunch of big words

i.e. you have as many connections as possible, but no two connections cross

[main token]

sounds like its gonna take more time than I'm willing to spend rn lol

[heady iris]

It's non-trivial

It's easy if you have a graph library. I did find one of those for a game jam a few months ago

it wasn't the worst to set up

[steady moat]

What look you are looking for ? Can you choose the position of the point ? Do you really need that no line cross ? What are you trying to represent ? Is it a 3D viewer ?

[main token]

It's mostly to visualize an algorithm I wrote which uses Divide and Conquer to find the pair of points with the smallest distance between them. Ideally I would want something like this:

I only want them to connect to reasonably adjacent points

[plush hedge]

@main token For each node, do a raycast within a limited distance towards each other node.

[heady iris]

you could approximate this by adding colliders each time you link up two nodes 🤔

[main token]

wdym, like checking intersecting colliders?

[heady iris]

yeah, you'd shoot a raycast to see if the path is clear

it'd be an approximation of an algorithm to generate a planar graph

[main token]

how would that be done in practice? Like raycasting towards a certain object, then comparing the object hit to the target?

[heady iris]

something like that

it would be very funky

[main token]

hey if it works, it works

[heady iris]

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

relevant concept

I remember seeing someone post a library for this on the unity forums a few years ago

a Delaunay triangulation avoids thin triangles

[plush hedge]

I would just do a POV graph (each node raycasts towards each other node), keeping track of all connections for each node. Then discarding all but the shortest connections and drawing them. It's naive and inefficient, but super simple to implement.

(POV: points of visibility)

Actually you don't need to raycast even

[solemn rune]

small question: How do you deal with properties in a Editor / Inspector script? How would I trigger certain functions after manually changing a public variable in the inspector?

[leaden ice]

The simplest way is OnValidate

the fancy way is a custom editor or a 3rd party plugin like this:
https://dbrizov.github.io/na-docs/attributes/meta_attributes/on_value_changed.html

[solemn rune]

Thanks. OnValidate() runs everytime any public property changed? Would there then be a way of knowing what value changed? Trying to wrap my head around how to implement it; Im not used to making extensive editor scripts 🙂

The NaughtyAttributes plugin seems more handy prob

[regal epoch]

anyone?

[solemn rune]

Thanks @leaden ice always on poin!!

[simple egret]

Your loop is infinite. The rndNameIndex you create inside the loop isn't the same as the rndNameIndex you check in the condition. Thus, the condition result will never change

Your code editor probably tells you that the variable inside the loop is unused, its name will have a faded color, compared to other variable names, as well as a suggestion to remove it

[regal epoch]

oh yea youre right. it doesnt say remove, but it is grayed out. Thanks

[hexed pecan]

Late reply but I have used this one, its decent

[solemn rune]

Question: I'm trying to make a custom editor where I can manipulate a (cubic) bezier curve

so far so good:

For the next step I'd like to add Nodes for P1 and P2 (the two tangents), so I can drag and drop them with the mouse.. Anybody any idea on how I'd go about that? Some terms to steer me in the right direction?

[steady moat]

This can come handy https://docs.unity3d.com/ScriptReference/Handles.PositionHandle.html

[solemn rune]

rotate the 3D handle so that it seems 2d, and draw it on the inspector rather then in the scene view?

[wintry crescent]

Hi, I'm working with configurable joints, and I'm trying to get the local position of an anchor through code. .targetPosition doesn't seem to do the trick, what can I use instead?

.anchor returns the local position unscaled and unrotated, it seems

[solemn rune]

How do I paste code here?

[steady moat]

Why are you doing a bezier ?

Is it for a spline editor ?

[solemn rune]

[CustomEditor(typeof(T_Bezier2))]
public class T_Bezier : Editor
{
    public override void OnInspectorGUI()
    {
        DrawDefaultInspector();
        Rect rect = GUILayoutUtility.GetRect(10, 1000, 200, 200);
        T_Bezier2 bez = (T_Bezier2)target;

        GUI.BeginClip(rect);

        Vector3 positionHandlesPosition = Handles.PositionHandle(new Vector3(200,200,0), Quaternion.Euler(new Vector3(0,0,0)) );
        Handles.DrawAAPolyLine(Texture2D.whiteTexture, 5, bez.points); 

        GUI.EndClip();

    }
}

this gives me null errors when I try to create a position handle in the Inspector, anyone any idea?

[steady moat]

You are not suppose to use it in an inspector

But in the scene.

[solemn rune]

I'm using calculated bezier curves in my code, and I'd like a visual way of editing them, rather then just using the numbers

[wintry crescent]

try OnDrawGizmos maybe

OnDrawGizmosSelected maybe

[steady moat]

OnSceneGUI

[solemn rune]

yeah i need it in the inspector. Looking into OnDrawGizmos!

[wintry crescent]

someone pls help. There must be a way to get the local/world position of the anchor. right?

[steady moat]

On draw gizmo is on the scene

[wintry crescent]

ondrawgizmos is scene, not inspector

sry

[solemn rune]

ahh okok. Yeah I need to be able to move nodes by dragging them with the mouse. I suspect I just draw tiny cubes in OnInspectorGUI, but I need to register the mouse clicks and movements

[steady moat]

What are you trying to do ? Doing this in the inspector seem unwell.

[solemn rune]

So P1 and P2 are the tangents, I would like to drag them in the visualization part, rather then having to set the numbers

[wintry crescent]

parentTransform.TransformPoint(joint.anchor) worked

[solemn rune]

and btw the bezier curve drawn there is done in OnInspectorGUI with Handles.DrawAAPolyLine, it's not just Windows' paint 😄

[steady moat]

What are you doing with your Bezier curve ?

[solemn rune]

I was actually looking into that. But you beat me to it 😄

[steady moat]

Like, what is your purpose.

[solemn rune]

I use it to calculate some specific physics / velocity calculations for my own physics engine

[steady moat]

Since when you need bezier curve for that ?

[solemn rune]

well, lets say Simulation of a physics engine lol.. Its neither here nor there, im really just trying to fix a inspector script 😛

[steady moat]

Is there any reason why you would not use the scene view ?

Like what are you doing with it.

Is it interpolation ?

[wintry crescent]

@solemn rune why don't you just use AnimationCurve? It's a cool 2D bezier curve editor, built in

[steady moat]

Kinda what I was going to suggest.

If you use it for interpolation at least.

[wintry crescent]

But it'll be slow for a physics engine
use trigonometry if u can

[solemn rune]

can i use that as part of a custom editor script?

[wintry crescent]

why not?

just put an animationcurve in your script

and it's there

[solemn rune]

Oh I am, this part is just the visualization of the formulas

[wintry crescent]

no custom editor required, even

[solemn rune]

Ahh ok, yeah I need the tangent positions etc for my formulas, cant use keys

[wintry crescent]

how about curve.Evaluate()?

[heady iris]

that just gives you the value at a specific point on the curve

iirc, animation curves store the tangents as slopes

[wintry crescent]

can't you calculate it though, from that

[steady moat]

You first need to have the curve

[solemn rune]

Yeah you prob could. But, I'm using quadratic and cubic beziers etc, already doing it in code etc

Plus, I like this part, learning about editor scripts and visualisation, it's a nice change of pace

[steady moat]

I still do not know why you are trying to make a bezier in the inspector. It is not really made for that.

[solemn rune]

Well, in essence, using bezier calculations is a more flexible way of Lerping or Slerping something

the bezier in the editor is just the visualization of the bezier calculations used

[steady moat]

Then you should try to convert your bezier curve into the animation curve editor

If you do not want to manipulate the point

But bezier curve are never used for Lerping

There are way to complex for that.

[solemn rune]

I use the bezier formulas to interpolate stuff.. and so far so good, especially since I do the calculations myself in script.. All I need is 3 or 4 Vec2s

the math is not That complex

[steady moat]

It is not complex as the math, but as the performance.

[solemn rune]

but it would be really heavy if I did that multiple times per frame, and then having to look that up in an animation curve yeah

[steady moat]

And unrequired flexibility

[heady iris]

i mean, not for lerping, sure

but it's very common to do transitions with cubic bezier curves in, say, web browsers

[steady moat]

It is like doing 3-4 lerp betwen 3-4 points

Pretty sure animator does not use bezier curve.

[solemn rune]

a simple quadratic bezier: position = (1.0f - t) * (1.0f - t) * p0 + 2.0f * (1.0f - t) * t * p1 + t * t * p2; It's not that heavy...

Granted I prob wouldnt use it in a shader or something, but in my use case it isnt impacting any performance at all. And, it gives me way more flexibility in interpolating

[wintry crescent]

How can I create a field, to which I will be able to attach either a rigidbody or a articulation body?
Both inherit from Component
I don't want anything else to be attachable

[potent sleet]

custom editor script ?

[wintry crescent]

I'd rather to avoid that. It's too much work for a simple task

[potent sleet]

it's not that much work really, you could just make a bool control which one can be inserted

hide the field depending on bool

[wintry crescent]

yea, but that's a whole other class
I guess I'll just make 2 fields, like the people who made the spring joints that I'm using did...
IDK why I was trying to be smart

[potent sleet]

eh it's more to do with if you can find a simpler way to a problem why not take it

[swift falcon]

can please anyone send me a video that has script for 2d health and attack i couldn't find any that actualy works ?

[potent sleet]

where did you look ?

I seriously doubt there is one that doesn't work especially in tutorials on youtube

[swift falcon]

no it just that it isn't what i want like if they show what i need there is no link to code and if there is a link to code it isn't what i want

[heady iris]

it's not going to be EXACTLY what you want

if it was, there would be no point in making a game, because it would already exist

[swift falcon]

not even close

[swift falcon]

just health and damage

[heady iris]

i seriously doubt that you're doing something so incredibly unique that all existing reference material is useless

health and damage is basically just making a number go up and down

[potent sleet]

agree this is also incredibly basic for this channel and should be in #💻┃code-beginner

[icy gate]

if we compare a value assign to a variable and instantiating an object, how many times more heavy is instantiating an object?

[potent sleet]

give an example .
wdym heavy ?

[wintry crescent]

comparing and assigning local variables is basically free
instantinating is very very heavy
it's not a competition
that said, depends what you're comparing, if you're doing something like transform.position then that's an internal call and can be slow at times

when you do it a lot

Camera.main is another thing like that

[icy gate]

I see

I was making a pool manager and thought, that's a lot of code to grab an object and store it, I started wondering if it's starting to be more slower than instantiating an object

[wintry crescent]

depends how you grab it

singleton? basically free
GameObject.Find? probably better instantiate

but if you're running it once (or rarely), it doesn't matter anyway

unless you're doing it at least every frame you're good with whatever solution you come up with

[wintry crescent]

so probably not worth it to worry about it much

[icy gate]

yup, thanks I'm using singleton for the manager and not using slow methods like get components, or find, so yeah, it's decently optimized

[wintry crescent]

singletons can be a bit much code, yes, but they are fast and very very cool
just remember that you should initialize it in Awake and call it in Start
and despite what documentation would lead you to believe, you can't actually initialize singletons in Awake, and call them from somewhere else in OnEnable, which, according to this
https://docs.unity3d.com/Manual/ExecutionOrder.html
should be possible.
In truth, OnEnable and Awake are called in order only on one object
Like
foreach (obj in objects)
{
obj.Awake();
obj.OnEnable();
}
or something like that
I'm saying it cuz it bit me in the ass once, and I didn't find the issue for a couple of hours...

[fathom pewter]

Hi there. Im trying to pause my game using a gamepad as our only way of controlling the game. Ive been trying to set time.timeScale = 0 to pause our game but i realize that this makes it impossible to use the pause menu. Is there a way to circumvent this?

[icy gate]

will keep it in mind, cause I feel it will happen to me too in the future, thanks for the infoo

[wintry crescent]

This is an extremely annoying issue
what I did, is I had a PauseManager with a static bool isPaused, and all objects checked it
or all objects derived from PausableObject, registered themselves on the PauseManager, and PauseManager called Pause and Unpause on those objects
but that's a ton of effort
I think there is a way to keep UI going despite timescale being 0, but I don't remember how it went

I am not sure if there is a way to do it
I think there could be

I'm not sure if fixedTimeStep won't keep going, meaning FixedUpdate will keep getting called though

[fathom pewter]

hmm okay. i appreciate your help

[wintry crescent]

Does anyone know, why, if I do something like this

joint.connectedArticulationBody = default;

or

joint.connectedArticulationBody = null;

I get an error "A joint can't connect the body to itself." but when I do the same with joint.connectedBody, there is no error?
the articulation body does not turn to null when I check in the inspector after it was called

[visual fractal]

The way unity handles code is rather confusing. How do I get collisions to disable if I press a key?

[heady iris]

that's a very vague statement

"the way unity handles code"

so you want to make an object stop colliding with anything when you push a key

[visual fractal]

Yes.

[visual fractal]

I say that because the errors are sometimes weird.

[heady iris]

yes, errors are sometimes weird

[heady iris]

you just need to disable its colliders, then

If you aren't using the new input system, then you'll just do something like this to get input

if (Input.GetKeyDown(KeyCode.F))
{
  // ...
}

[visual fractal]

OK... I'll try that.

[heady iris]

disabling colliders is like disabling any other behaviour: set the .enabled field of the behaviour to false

you can stick a list of colliders on a component with

public List<Collider> colliders;

and then iterate over all of them to turn them on and off

foreach (var collider in colliders)
  collider.enabled = false;

[visual fractal]

Ah. That's what I was struggling with. Thanks.

[junior pollen]

hello, i have a problem with my 2d rigidbody jumping, tried separating the input and physics into Update and Fixedupdate but my jump height is still determined by the player's velocity, what i need is consistent jumps whenever i try to double jump https://gdl.space/zabobeqofe.cs

[visual fractal]

Try using ForceMode. Then you can choose whether or not to use velocity, mass, air friction, ect.

[junior pollen]

i tried using addforce

tried both with impulse and force but it doesn't work for some reason

[visual fractal]

Are there no more options?

[junior pollen]

not sure

[visual fractal]

Which part of the code is this? I'm on the link you sent.

[heady iris]

so the double jump is the inconsistent one?

or is the first jump the problem

[junior pollen]

yep

double jump depends on the player velocity

[earnest gazelle]

Is there any way to rename a word in all places, classes, properties, methods, etc.? jetbrains rider
For example StuffManager class, StuffType enum, _stuff field, stuff variable, DoStuff() method.
Replace Stuff/stuff with a new word

[junior pollen]

so the sooner you press the higher you go

[heady iris]

rb.velocity = new Vector3(rb.velocity.x, doublejumpForce - rb.velocity.y);

why doesn't this just set the y velocity?

[junior pollen]

?

i feel like this line was useless

[heady iris]

it sets your y velocity to doubleJumpForce minus your current y velocity

[junior pollen]

i tried to do something like rb.velocity -= rb.velocity.y

but ig that doesn't work?

[heady iris]

what do you want to do?

you can't just do random math

[junior pollen]

realised that

basically consistent double jumps

[heady iris]

then just set the y velocity

like you do for the single jump

[visual fractal]

Maybe try doubleJumpForce + rb.velocity.y.

[heady iris]

yes, this would also be reasonable

it would make the second jump make you move faster than you were

[junior pollen]

hm

[visual fractal]

Or just add the force of a single jump to your y velocity.

[junior pollen]

but rb.velocity.y is a vector2 and JumpForce is a float

would that still work?

[visual fractal]

Convert the Jumpforce into a vector.

You can do that with C#, right?

[junior pollen]

ah like new Vector2(rb.velocity.x, jumpForce)

?

[junior pollen]

wdym

[heady iris]

rb.velocity = new Vector2(rb.velocity.x, jumpForce);

you already do this

just...do it again

[junior pollen]

that'll make both jumps equal

[visual fractal]

I haven't had to do it yet.

[heady iris]

then do the double jump differently!

rb.velocity = new Vector2(rb.velocity.x, jumpForce + rb.velocity.y);

[junior pollen]

ah

why not just use doublejumpForce instead of jumpForce?

[visual fractal]

Try that.

It'll probably work.

[junior pollen]

like if i want the doubleJump to be consistent but different height value than the jumpForce

[heady iris]

sure

[junior pollen]

yep

[heady iris]

use a different number

[junior pollen]

:/

double jump still the same

i feel like i need a way to completely reset the y velocity to 0 and then double jump

[visual fractal]

You could write the code like I did. It's not the right way of doing it, but its allows double jumps.

And triple, quadruple, and any other jumps that you might need.

[junior pollen]

hm

i'll try finding a fix, if that doesn't work then sure

[visual fractal]

And if you hold the jump button you continuously go upwards...

[junior pollen]

uhhhh

that is flying...

[visual fractal]

It's buggy, but it works.

[junior pollen]

well it can probably be fixed

[visual fractal]

Yes, I coded it like this for a deliberate glitch in the game I'm making.

[junior pollen]

ah nice

[visual fractal]

The referenced script (Unknown) on this Behaviour is missing!

What is this?

[junior pollen]

tried doing this in the double jump couroutine but it also didn't work :/
rb.velocity = new Vector2(rb.velocity.x, 0);
rb.velocity = new Vector2(rb.velocity.x, doublejumpForce);

[junior pollen]

?

[visual fractal]

This.

[junior pollen]

yes where did you see/get that error

[visual fractal]

The debug log.

[junior pollen]

uhh

[visual fractal]

?

[junior pollen]

im confused, you talking about my code or yours?

[visual fractal]

Mine.

I accidentally replied to your message.

[junior pollen]

yep

[visual fractal]

Everything in my code is working, it's just displaying the warning.

[junior pollen]

you probably deleted a script that you had assigned on a prefab or something

basically nothing

[junior pollen]

(i think that's what it is)

[visual fractal]

Probably correct, but how do I stop it?

[junior pollen]

check the prefabs that you made to try and find a missing script on the script component

[random oak]

how would I count these squares on tilemap by a certain amount ? the white dots

[visual fractal]

As far as I know, all the prefabs are assigned.

[junior pollen]

wait

check your c# script

it should say public class (the c# script name)

or else the script won't work

the class definition of a script needs to be the same as it's name

[wintry crescent]

How can I easily do an OnComponentAdd and OnComponentRemove inside a component?
I want to set the layer of the object to something when a component is added, and changed to default when it is removed

[leaden ice]

OnDisable/ OnEnable

[hollow hound]

How can I get the contact position for the collider (onTrigger)?

[woeful furnace]

Doesnt the collider passed in contain the transform which has the position so like other.transform.posistion I dont know for sure.

[hollow hound]

I want the exact spot/spots of a collision(trigger), not the position of the other collider.

[leaden ice]

OnTriggerEnter doesn't provide contact points, because there is no contact

Just an overlap

[hollow hound]

Can I somehow get the overlap area and/or position?

I think I can get bounds of two colliders and find an overlap myself, but is there a more efficient way?

[somber nacelle]

What is the purpose for this?

[void basalt]

Are you trying to depenetrate two colliders?

https://docs.unity3d.com/ScriptReference/Physics.ComputePenetration.html

Regardless of the purpose, this should give you exactly what you need

[rugged storm]

hay is this a good way to iterate through a list of targets to find which is the closest?

[glossy basin]

Hello there, has somebody used UniTask before? I am having some issues with it

[rugged storm]

I feel like what I did works but could be improved so I wanted to ask here

[glossy basin]

My uni task state is always pending, so whenever a new task is added, it stays there

[cosmic rain]

Gotta share some code.

[glossy basin]

So, here is my infinite generator code

https://hastebin.com/share/ipowihuwot.java

I have literally 0 knowledge on both task and UniTask, I just followed some guides, so any help would be appreciated 😄

here is the async function that waits for generating the chunks

and here is the function that generates the actual chunk

[cosmic rain]

What's dataJobHandle here?

I'd also be extra careful with calling async methods from update.

[glossy basin]

data job handle is a JobHandle I use for generating world data, here is the code of that

[cosmic rain]

And where is that called?

Or rather, why is your task waiting for it to finish?

[glossy basin]

On the first line of this code, on the ternary condition

[cosmic rain]

Wait. It's waiting while it is finished. Is that waht you want?

The task would only complete when this job is runing.

[glossy basin]

I assumed I had to put the job handle status on the wait while in order to run the task, is it wrong?

[cosmic rain]

Wait while implies that when the condition is true, you wait.

[clever pier]

do you guys know any thing about lag compensation?

[glossy basin]

How would I aproach this instead of using Update?

[cosmic rain]

#archived-networking

[clever pier]

thanks

[cosmic rain]

I'm not sure update is the issue here. I just mentioned that you should be careful to make sure that your tasks don't snowball over several frames.

[glossy basin]

I actually thing this may be the case

the profiler shows me an INSANE amount of calls to the async

[cosmic rain]

Okay, well, you could make clear logic that would track if a task is currently running, and avoid starting a new one.

[glossy basin]

I guess this is also the reason I get some garbage from time to time

[glossy basin]

I guess this can be held using a simple boolean, right?

[cosmic rain]

Yes. You could set refreshing bool to true when you start refreshing and set it to false when it's done.

[distant venture]

Question: In a script, I'm unable to reference one type of interface, and yet I'm able to reference another type of interface defined under the same conditions and namespace. Does anyone have any idea why?

[cosmic rain]

Not without seeing your code/errors

[distant venture]

I'm getting this error: The type or namespace name 'IInteractable' could not be found (are you missing a using directive or an assembly reference?)

[cosmic rain]

Just to be clear, you get this error in the ide?

[distant venture]

Yes, correct, Visual Studio Code.

[glossy basin]

This looks like your class name is not the same as the inteface name

[cosmic rain]

Ok, share the code where you define the interface and where you try to access it.

[distant venture]

I'm able to reference this interface in question in another script, just not in this script for some reason.

[glossy basin]

Hmm, maybe you set a namespace for the interface and you are not using it in the other script?

[cosmic rain]

It will make it so much easier for everyone if you just shared the relevant code

[distant venture]

`using System.Collections;
using System.Collections.Generic;
using UnityEngine;

namespace Cleverous.VaultInventory
{
public interface IInteractable
{
Transform transform { get; }

    void Interact();
}

}`

[cosmic rain]

And the script where you try to access it?

[distant venture]

`namespace Cleverous.VaultInventory
{
[RequireComponent(typeof(Collider))]
public class RuntimeItemProxy : NetworkBehaviour
{

...

    public virtual void TryPickup(IUseInventory requestor)
    {
        IUseInventory inventory = null;
        IInteractable interactable = null;

...`

I'm sorry, the script is quite long, so I've tried to abbreviate it.

[dense stream]

hi is there anyone here?

can i get some help with a code problem i have

[cosmic rain]

Ok, seems okay I guess. Unless IInteractable is in a different assembly, it should work.

[cosmic rain]

Don't ask to ask...

[dense stream]

hi

@cosmic rain hi nice to meet u

[cosmic rain]

This is not the #🤝┃introductions chanel. If you have a question, ask right away.

Also, I see that you're getting help in the other channel. Please don't cross post

[dense stream]

sorry duley noted thank u @cosmic rain

[distant venture]

I don't think it's in a different assembly, I'm not sure what I should even try to do ...

[cosmic rain]

First of all,comment out everything causing a compile error, make sure your code is recompiled and try to reference the interface again.

Also, if the error only happens in VS code and not in unity, there's probably something wrong with your code editor.

[distant venture]

OK, I appreciate the help, I'll look into that.

[cosmic rain]

Also it goes without saying, but your code files all need to be in the Assets folder of your project.

[distant venture]

I'm getting the error in Unity as well.

[distant venture]

Yes, they're all in the Assets folder.

[cosmic rain]

Ok, can you take take a screenshot of where the 2 files are located physically?

[cosmic rain]

Are you making use of assembly definitions in your project perhaps?

[distant venture]

https://www.youtube.com/watch?v=HYqOSkHI674
I'm watching this video, because I don't know what that is, lol.

[distant venture]

I'm making use of someone else's inventory project, so perhaps this is a question for them, I'll ask on their Discord.

@cosmic rain I appreciate your time and help so far. Thank you.

[cosmic rain]

If they're using assembly definitions and one of the files in question enter that assembly, while the other one doesn't, it could be the cause of the issue.

[distant venture]

@cosmic rain The answer is yes.

[cosmic rain]

Well, then that's probably the problem.

[distant venture]

@cosmic rain As a workaround, I guess I'll try to move this function over to another script, or something like that. Thank you for your help, you saved me a lot of headache.

[cosmic rain]

I'd advice learning about assembly definitions properly instead. If you're gonna include them in your project, there might be other issues I'm the future.

[distant venture]

OK, I really have no concept of what they are, so you're absolutely right.

[smoky pike]

I have two vectors - v1 and v2 and need to find the angle theta relative to the x-axis. How would I go about doing so? I current am just doing atan(v2.y-v1.y/v2.x-v1.x), but the angle is computed incorrectly when I'm in any quadrant other than the first one.

[void basalt]

@smoky pikeatan2?

[smoky pike]

ooh thank you didn't know about that one

[shell scarab]

not being able to use the ?? operator on unity objects is a travesty

[swift falcon]

use ternary

[shell scarab]

yes ik. I'm just sad I have to do

get => _instance != null ? _instance : new();
```rather than
```cs
get => _instance ?? (_instance = new());

[swift falcon]

get => !_instance ? _instance : new ();

pretty much same length

[smoky pike]

How would I integrate this with a Quaternion? I have the angle and am instantiating a line with that angle at a certain point: Quaternion.Euler(0f,0f,angle); but the angle of the lines seem to be instantiated in the 2nd quadrant

[shell scarab]

I find comparing game objects to bools gross

[void basalt]

No clue. Someone else is gonna have to answer that

[shell scarab]

there's nothing different than comparing to null as far as i know

[swift falcon]

the bool is just doing the != null behind the scenes:3

[shell scarab]

are you trying to rotate a vector with a quaternion?

[shell scarab]

yes but gross (this is my opinion, I think it's too unclear, it's a totally valid way to do it)

[smoky pike]

I am instantiating a gameobject with the angle I just computed: Instantiate(gameObject, new Vector2(pos.x,pos.y), Quaternion.Euler(0f,0f,angle );

[plucky karma]

Why not ```cs
get => _instance ??= new();

[shell scarab]

try doing

GameObject o = Instantiate(gameObject, new Vector2(pos.x,pos.y), Quaternion.Identity;
o.transform.forward = Quaternion.Euler(0f, 0f, angle) * Vector3.forward;

[shell scarab]

because unity can't override the ?? operator

[plucky karma]

Don't use Monobehaviour objects?

[shell scarab]

also cool, I honestly didn't know you can do ??=

[shell scarab]

No i have to

[swift falcon]

this works for uity objects?

[shell scarab]

way easier access for peeps to modify the values of the singleton

[shell scarab]

no

[plucky karma]

No this does not.

[swift falcon]

I thought it does

[plucky karma]

??= only works if left hand is "true" null.

Not boolean value that unity overrode.

[shell scarab]

https://github.com/microsoft/Microsoft.Unity.Analyzers/blob/main/doc/USP0001.md

If you use the == operator to compare a UnityEngine.Object to null, it will return true if the UnityEngine.Object is destroyed, even if the object itself isn't actually null. The ?? operator cannot be overridden in this way, and therefore behaves inconsistently with the == operator, because it checks for null in a different way.

[plucky karma]

Plus, I think internally, you can't access the constructor? It's also marked private?

[shell scarab]

I've never had a problem doing new GameObject()

also I realize what I told you to do would do nothing, I was assuming you had the quaternion you wanted @smoky pike

you need help getting the quaternion, right?

[smoky pike]

yes

[shell scarab]

and you're on a 2D plane, and want to make the object face that angle?

[smoky pike]

yep

[shell scarab]

did you get it working with atan2?

[smoky pike]

i got the angles which seem to be correct

[shell scarab]

try doing

transform.right = (Vector2)(Quaternion.Euler(0,0,angle) * Vector2.right)

off the top of my head I think that'll rotate the right vector to the correct angle

[smoky pike]

the transform for the instantiated gameobject correct?

[smoky pike]

yeah that works tysm for the help

[shell scarab]

This isn't really a coding question, but yayyy I have a null pointer to a gameobject, what do i do? I can't delete it. (the script error is because it's supposed to have a reference to that object)

[void basalt]

Press clear in console

oh you mean it comes up when you press play

[shell scarab]

yes it does

it's not gonna fix a null pointer to this broken game object lol

[void basalt]

Pretty odd error. GameObjects on the backend are native C++ objects I'm pretty sure

are you using unsafe code?

[shell scarab]

nope!

[void basalt]

In the editor

the gameobject is greyed out

so that likely has something to do with it

[shell scarab]

parts of unity have c# pointers, so maybe it's not in the c++ part lol

[dusk apex]

https://stackoverflow.com/a/68557338

Probably the error is due to the fact that you are destroying some prefab that is not unpacked, so not destroyable by the runtime GameObject.Destroy that is to destroy a cloned copy from the scene.

[visual fractal]

'PlayerMotor' does not contain a definition for 'Move' and no accessible extension method 'Move' accepting a first argument of type 'PlayerMotor' could be found. Please help. I don't understand a majority of these error messages.

[void basalt]

Then you should be in beginner

nobody can help you without posting code either

[visual fractal]

Good point.

[shell scarab]

#💻┃code-beginner

ok I fixed it.

I edited the scene file in notepad++ and found the broken gameObject (not that hard considering there's not many lol) and just deleted the text for it and now it's fine!

[amber haven]

When finding the distance between a client and an enemy, I run the command every frame to detect distance, all that is changing is the enemies and clients position by very small increments, yet I get random extreme outliers like this (see distance from target). Any ideas on how I can fix this. Btw both the client and host are run from the same pc so I don't think its a lag problem. Help with this would be greatly appreciated.

[cosmic rain]

For starters, looking at the code could be helpful

[amber haven]

if(!IsHost){return;}

HostDistance = Vector3.Distance(NetworkManager.Singleton.ConnectedClients[0].PlayerObject.transform.position, Dalek.transform.position);
ClientDistance = Vector3.Distance(NetworkManager.Singleton.ConnectedClients[1].PlayerObject.transform.position, Dalek.transform.position);

if(HostDistance < ClientDistance)
{
    Target = NetworkManager.Singleton.ConnectedClients[0].PlayerObject;
    print("Distance from Target: " + HostDistance + "\n" + "Distance from Non-Target: " + ClientDistance + "\n" + "Target: " + "Host");
}
if(HostDistance > ClientDistance)
{
    Target = NetworkManager.Singleton.ConnectedClients[1].PlayerObject;
    print("Distance from Target: " + ClientDistance + "\n" + "Distance from Non-Target: " + HostDistance + "\n" + "Target: " + "Client");
}
```Run in update

[cosmic rain]

I'd check if Dalek, ConnectedClients[0] and ConnectedClients[1] always refer to the same objects.

[amber haven]

Yeah they are always referring to the same object

The only time they wouldnt be is if I was hosting the game via the build instead of through the editor.

[cosmic rain]

Are you sure? Maybe print their names along the debug log?

If they are, then something's moving them to weird positions for a frame

According to your logs.

[amber haven]

Yeah

[amber haven]

I'll do that

rn the naming system is just auto assigned, 0 is always the host and 1,2,3 etc are always clients.

[orchid bane]

Does Transform.InverseTransformVector only change the representation of the vector or the vector gets changed instead?

[amber haven]

Target: [Host] Name: 0
Distance from Target: 67.07581
Distance from Non-Target: 77.5272

Target: [Host] Name: 0
Distance from Target: 27.38524
Distance from Non-Target: 67.06821

Target: [Client] Name: 1
Distance from Target: 67.05099
Distance from Non-Target: 77.54034

Its still happening randomly, here is a new log that also shows names

[cosmic rain]

What about Dalek?

[amber haven]

Like the daleks distance from the players?

[cosmic rain]

No. The object's name

[amber haven]

Ah no, I am measuring the distance between the players and the dalek.

[cosmic rain]

Yes, that why I'm asking

Here's how you log needs to look like to provide good debug info:

Distance from player0 to Dalek0: 3637
Distance from player1 to Dalek0: 3648

[amber haven]

Okay I'll rewrite them in that format

[amber haven]

Distance from player0(Host) to Dalek0: 8.965793
Distance from player1(Client) to Dalek0: 7.23741
Closest player is player1

Distance from player0(Host) to Dalek0: 8.914283
Distance from player1(Client) to Dalek0: 14.93916
Closest player is player0

Distance from player0(Host) to Dalek0: 9.003682
Distance from player1(Client) to Dalek0: 7.063987
Closest player is player1

Okay here is another extract from the logs using your formatting showing the randomly changing positions.

The dalek is a nav mesh agent so could it be that randomly tping it somewhere for a frame?

[cosmic rain]

Okay. So at least it's clear that it's player1 position that jumps.

[amber haven]

Yeah

I have noticed its only on the client

the client is run on a built version whereas the host is run through editor

thats the only difference I can think of

[cosmic rain]

Did you try logging the same stuff on the actual client?

Or is on the client?

Or the host?

[amber haven]

The host

I will also run it on the client if that helps

[cosmic rain]

Ok, and is it a host authoritative game?

Where is the player1 moved?

[amber haven]

No its player authoritative

[amber haven]

Idk I am not changing its position only it is through keyboard controls.

[cosmic rain]

Ok, so outputting same logs on the client could help.

[amber haven]

i cant see any visual change in the players position for a frame if thats what you mean.

Its only in the logs

[cosmic rain]

1 frame could easily be missed by a human eye.

[amber haven]

true

if I record it at 60fps and have the application set to 60fps it should capture every frame right?

then run through in a video editing software frame by frame

[cosmic rain]

If you confirm via the log that the issue doesn't happen on the client, then it must be something about syncing positions between the client and the host.

[amber haven]

yeah

[cosmic rain]

Why go so far when you can just print logs on the client? Lol

[amber haven]

I could have the player send their position to the host via an rpc rather than by the dalek checking the players position through its object on host side?

[cosmic rain]

You're thinking about walk-arounds before you even understand the issue. That's not how debugging works.

[amber haven]

Okay

I'll set up the client side logger

[amber haven]

I'm just getting a "NotServerException: ConnectedClients should only be accessed on server." error, which is understandable, can I give clients access?

[cosmic rain]

What exactly throws that error?

[amber haven]

I'm pretty sure its

HostDistance = Vector3.Distance(NetworkManager.Singleton.ConnectedClients[0].PlayerObject.transform.position, Dalek.transform.position);

ClientDistance = Vector3.Distance(NetworkManager.Singleton.ConnectedClients[1].PlayerObject.transform.position, Dalek.transform.position);

[cosmic rain]

On the local client you should have an access to the player character directly. You don't need to reference it via the Network manager.

[amber haven]

have found the fix, It works but only if nobody is in the pause menu.

I have it so that when you press tab the player movement script is temporarily disabled

and you mouse is unlocked from the screen

The pause menu has no connection to the dalek code

so idk why this is happening

[cosmic rain]

Why would Dalek code matter at all? The issue was with the player position.

[amber haven]

I agree

[cosmic rain]

When you disable the movement controller, it either does something with the position itself or with what/how it syncs with the host.

That's what I can guess from the limited information available at least.

[amber haven]

I'll send the code

[amber haven]

    void Update()
    {
        if(Input.GetKeyDown(KeyCode.Tab))
        {
            if(MouseStatus == "Enabled")
            {
                Cursor.lockState = CursorLockMode.None;
                MouseStatus = "Disabled";
                GetComponent<InputManager>().enabled = false;
            }else if(MouseStatus == "Disabled" || MouseStatus == "GameOpenState" )
            {
                Cursor.lockState = CursorLockMode.Locked;
                MouseStatus = "Enabled";
                GetComponent<InputManager>().enabled = true;
            }
        }
    }

[ashen yoke]

you know how ref counting is done?

or any similar application

[cosmic rain]

Ok, and what does the InputManager do?

[ashen yoke]

please replace string literals with consts

[amber haven]

    private PlayerInput playerInput;
    private PlayerInput.OnFootActions onFoot;

    private PlayerMotor motor;
    private PlayerLook look;

    void Awake()
    {
        playerInput = new PlayerInput();
        onFoot = playerInput.OnFoot;
        motor = GetComponent<PlayerMotor>();
        look = GetComponent<PlayerLook>();
        onFoot.Jump.performed += ctx => motor.Jump();
        onFoot.Crouch.performed += ctx => motor.Crouch();

        onFoot.Sprint.performed += ctx => motor.startSprint();
        onFoot.Sprint.canceled += ctx => motor.endSprint();
    }
    void FixedUpdate()
    {
        motor.ProcessMove(onFoot.Movement.ReadValue<Vector2>());
    }
    private void LateUpdate()
    {
        look.ProcessLook(onFoot.Look.ReadValue<Vector2>());
    }
    private void OnEnable()
    {
        onFoot.Enable();
    }
    private void OnDisable()
    {
        onFoot.Disable();
    }

[cosmic rain]

Yeah, an enum would be suitable there.

[ashen yoke]

one easy approach to solving similar situation is to keep a stack

or a counter

if its empty the thing is allowed to happen

every time some menu opens it either adds to counter or gets a "token" that it holds

other systems react to the stack being empty or having something, disabling themselves

solves a lot of issues like ui panel hirarchies, stacked input maps etc

[cosmic rain]

It's kinda hard to figure out just from looking at the code, but there's probably something going on with your input(or how you consume it) when you enable/disable this script. I'd check the values passed into ProcessMove around the time the issue happens.

[amber haven]

Incase it was using values from before it was disabled?

[cosmic rain]

Something like that

[amber haven]

I'll try disabling the input script instead of disabling the movement script itself

It'll do the same thing without halting calculations done by the movement system, which fixes another bug of how the player doesnt fall when in menu

[orchid bane]

I have a Vector3 in world space. And I have a Transform which I want to use for this Vector3 as world space meaning I want the vector to have the same rotation as the transform. How do I do it?

[ashen yoke]

you have a direction vector?

transform already comes with transform.forward which is z+ in world space direction

[orchid bane]

The vector isn't a Vector3.forward but another vector like (-10f, 5f, 3,4f)

[ashen yoke]

i never said Vector3.forward

[orchid bane]

Why did you mention transform.forward then

[ashen yoke]

those are completely different things

thats why i mentioned it

[orchid bane]

[shell scarab]

so your picture doesn't match your original description:

I have a Vector3 in world space. And I have a Transform which I want to use for this Vector3 as world space meaning I want the vector to have the same rotation as the transform. How do I do it?
That vector doesn't have the same rotation as the transform nor is it the same vector but in local space. But perhaps Transform.InverseTransformDirection will help you? https://docs.unity3d.com/ScriptReference/Transform.InverseTransformDirection.html
Transforms a direction from world space to local space.

[hollow hound]

I'm want to get the position/positions of the penetration.
Ideally some coordinates of the yellow area and/or green point.

[void basalt]

you're likely going to have to rig something up with computepenetration

[hollow hound]

What do you mean by "rig up"?

[shell scarab]

they mean code something using CompuitePenetration.
https://docs.unity3d.com/ScriptReference/Physics.ComputePenetration.html

[hollow hound]

I did check the docs, but I don't completely understand how it can solve the problem besides trying to check every point (with some spaces i guess) of the first collider. As far as I understand, ComputePenetration takes two colliders and a point, returns if colliders overlaps at this point.

[shell scarab]

just get a collision point and use that method to check if they're overlapping on the collision point?

[hollow hound]

just get a collision point
How?
Actually, my initial question was "how to get collision point(s) if the two colliders".
And as far as I understand, there are no build in method for it.

[ashen yoke]

it returns you a vector

[shell scarab]

with the OnCollision method you can use collision.contacts

[ashen yoke]

by which you offset the object so they dont overlap anymore

[shell scarab]

https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html
https://docs.unity3d.com/ScriptReference/Collision.html

The contact points generated by the physics engine. You should avoid using this as it produces memory garbage. Use GetContact or GetContacts instead.

https://docs.unity3d.com/ScriptReference/Collision.GetContacts.html

Retrieves all contact points for this collision.

[ashen yoke]

what should the green point represent?

[hollow hound]

I have colliders in the onTrigger. There are no contacts calculated for this type of overlaping.

[ashen yoke]

is the trigger axis aligned?

if it is you do something like https://docs.unity3d.com/ScriptReference/Bounds.ClosestPoint.html on the centroid

can do something like it

[shell scarab]

couldn't you do OnTriggerEnter() then use other.ClosestPoint(transform.position)?

https://docs.unity3d.com/ScriptReference/Collider.ClosestPoint.html

[ashen yoke]

woo nice one

[shell scarab]

you gave bounds and they might not think there's an equivalent for a collider, which includes rotation.

wait @hollow hound is this 2D?

[hollow hound]

Point on the surface of the second collider that are in the overlap and is

1. nearest to the origin
2. or center of the overlapped surface line

[hollow hound]

Yes

[shell scarab]

https://docs.unity3d.com/ScriptReference/Collider2D.OverlapPoint.html & https://docs.unity3d.com/ScriptReference/Collider2D.OverlapCollider.html won't work?

[hollow hound]

It will give point outside the overlap. I need basically the same, but inside overlapped area

[shell scarab]

what? That doesn't give a point. Wait, that reply is weird.

[hollow hound]

So the OverlapPoint again brings us to the solution if the checking all points (with some spaces) of the collier, which is kinda working but seems way too inefficient and not precise.
OverlapCollider just gives the colliders that are overlapping with this collider, right?

[leaden ice]

What's the use case for this?

[hollow hound]

No, they can be with different angle, if I understand correctly what you are asking about.

[leaden ice]

Like are you:

• trying to draw something
• trying to calculate volume of overlapping area?
• trying to spawn something at contact points?

Etc

[ashen yoke]

can you raycast from the centroid towards movement vector

i dont know if you can hit trigger, you should right?

[hollow hound]

Find a point of the hit of the hitbox to spawn there another entity.
General question would be: How to find point that is on the surface of area of the overlapping / of two colliders and nearest to the another given point. Preferably without iterating through points in the collider.

[leaden ice]

I would track the previous position of my object in FixedUpdate, then when the collision happens do a BoxCast for example from previous position to current

That will get you "contact points"

[hollow hound]

The thing is, there are no movement, trigger collision just spawns in place (but there can be in a general case)

[ashen yoke]

if all fails my sleep deprived mind just came up with an idea to keep parallel physics world with kinematic/non kinematic colliders mirroring objects and triggers to get collision points

[hollow hound]

The trigger is being spawn, there is no previous position of it.

[ashen yoke]

or alternatively turn trigger into kinematic and write your own trigger

[hollow hound]

So will try to formulate my question one more time in case it was too abstract.
I want to find a point (green) on the surface (blue) of the area (yellow) of the two overlapping trigger colliders (grey), that is nearest to the another given point (red).
Preferably without iterating through points in the collider. There are can be some movement, but it's not always the case (so I can't rely on previous position and need to work with static colliders). The shape of the colliders can be more complex than boxes and circles. All this in 2d.

[leaden ice]

If you have the given red point you can use https://docs.unity3d.com/ScriptReference/Collider2D.ClosestPoint.html

[hollow hound]

If I understand correctly, this will give the point on the surface of the collider, not on the surface of the overlapping area.
It will give me the blue pint, right? But I need the green one.

[leaden ice]

https://docs.unity3d.com/ScriptReference/Collider2D.Cast.html might work.

See what happens if you use Vector2.zero as the cast direction

[void remnant]

hello! is it possible to make a shader that does the effect shown in my scuffed image? Basically, you add the material to the mesh and it generates a water effect above it: waves on a set height and underwater effect in between the ocean floor and water waves level (less light, everything is blue etc).

[swift falcon]

I'm having an issue where my game character just floats randomly

Code: https://gdl.space/oqeyanehuh.cs

[thin aurora]

You definitely need to provide some more context instead of slapping the code in here and expecting an answer

[swift falcon]

hmm

you want the player inspector?

[thin aurora]

A video, specific instructions on how the code works, or stuff like that

Try loggin the values you use and see what goes wrong

[swift falcon]

this is the inspector

[swift falcon]

I tried that

it stays the same

I'll record a video

hold on

[leaden ice]

What debugging steps have you taken so far?
What does "just floats randomly" actually mean?

Also looks like networking is involved which complicates things a lot

[swift falcon]

at first when I create a world everything is fine and I can jump and stuff

I fall down onto the ground slowly

what's confusing is

everything is only fine

when the caves are still generating

when they stop

I start to float

[leaden ice]

What debugging steps have you taken

[swift falcon]

but ik it has nothing to do with caves

[swift falcon]

well I've pretty much just searched through the code and tried to change some inspector values

nothing happened

[wooden jewel]

I have this block of code that reads asset from a folder. It works fine in Unity Editor, but in standalone build, it cannot find the folder. How can I fix this ?

[leaden ice]

You should start adding log statements and questioning your assumptions about the code

[leaden ice]

The assets folder and .asset files don't exist anymore in a build

[wooden jewel]

So how should I handle this approach ?

[leaden ice]

https://docs.unity3d.com/ScriptReference/Resources.LoadAll.html

[wooden jewel]

Thank you very much!

[fallen epoch]

I have a couple of problems currently.

1. I have a shader that (should) apply bloom and can apply a dissolve effect. The bloom isn't showing, I have a PP volume with bloom active so I don't know why it isn't working.

2. I don't know how to go about making that dissolve effect happen while keeping the rest of the game paused. I've looked a bit into changing the time scale to 0 and coroutine looping a lerp for it but I can't quite get the logic working out so it doesn't stop entirely or runs the entire lerp during a single frame.

Help please ❤️

[sleek bough]

1 - #archived-shaders
2 - https://docs.unity3d.com/ScriptReference/WaitForSecondsRealtime.html

[fallen epoch]

Yeah, I found WaitForSecondsRealtime but couldn't mentally figure out how to use it for what I want 😅
Being sick doesn't help my brain function though, and thanks for the shaders channel reminder!!

[sleek bough]

#archived-shaders that is if you are using custom shader for post processing, otherwise it's #💥┃post-processing

[sleek bough]

Coroutine time await function will use scaled deltaTime. For things like animating UI you want to use realtime one so they won't be affected

[fallen epoch]

I'll fiddle with it and come back if I'm somehow working myself into a mental dead end. Helps to have some code to reference too 😅

[ember ore]

How do you usually avoid that something spawns inside another Object?
Or for example that something is perfectly placed?

E.g. Imagine you highlight some part of a Gameobject or whatever. You want to spawn in an Arrow pointing on that highlighted part.
So how do you programatically place that arrow that it does not spawn in the gameobject itself? This is more theoretically...
In the attached image it should spawn perfectly in the space outside the gameobject itself.

Are there some algorithms for this? How would you do that?

[hollow hound]

It draws the point outside overlap and not on the surface 😦
I'm trying Collider.Cast(Vector2.zero, results); and then using the first point in the results array.
Honestly I don't completely understand what is "cast shape into the Scene".
Am I using this function correctly?

[quartz folio]

No, because Vector2.zero is not a valid direction.
A cast moves an object through the scene, not moving it at all is not a cast, it would be an overlap

I see that was recommended to you... in that case the docs say what it returns

Additionally, this will also detect other Collider(s) at the collider start position if they are overlapping. In this case the cast shape will be starting inside the Collider and may not intersect the Collider surface. This means that the collision normal cannot be calculated in which case the collision normal returned is set to the inverse of the direction vector being tested.

[fallen epoch]

Vector2.zero is (0,0), points nowhere and provides no direction - makes sense you would get nothing from trying it. I'd expect some warning or debug log though

[ember ore]

Anyone?

[hollow hound]

I understand that, just tried what was said. I don't think it doing what I need anyway.

[hollow hound]

If I'm trying the yellow point as a direction the result looks like this.

So there no mechanism to get the overlapping area and working with it (find a point inside it, for example)?

[heady iris]

I'm having trouble understanding what you want.

do you want to get a position that's in the overlap between the rectangle and the line?

[hollow hound]

I want to find a point (green) on the surface (blue) of the area (yellow) of the two overlapping trigger colliders (grey), that is nearest to the another given point (red).
Preferably without iterating through points in the collider. The shape of the colliders can be more complex than boxes and circles. All this in 2d.

[heady iris]

hmmmm, that could get tricky fast

i'm reminded of stuff like https://en.wikipedia.org/wiki/Gilbert–Johnson–Keerthi_distance_algorithm

..which is basically collision detection itself!

I wonder if you could use non-triggers. You get a set of contact points.

not sure how usable that data would be

[plain coyote]

I am using 2022 unity, is there a place where I know which version of dotnet unity supports?

[quartz folio]

https://docs.unity3d.com/2022.2/Documentation/Manual/dotnetProfileSupport.html

[heady iris]

tbh, the most obvious solution to me is to do a batch of raycasts

[hollow hound]

I wanted, but the problem is that collision pushes objects away and I don't want to move them.

[plain coyote]

I am not sure about how you define the green dot?
is it like the closest point in the overlapped area to the red point?

[heady iris]

yeah

so:

• intersect two colliders
• find the closest point

here's one thought

the green dot will be located at one of two places

[hollow hound]

Ideally to the surface of the overlapped area because red point can be inside of it, but yeah

[heady iris]

it could be on one of the corners of the intersection area

or it could be the closest point to the original collider

but I don't see any obvious way to get those corners from triggers overlapping

[heady iris]

I vaguely remember seeing a way to do this..

i feel like i'm back in my 4000-level algorithms class, haha

will this be on the exam

[mental rover]

this is the type of thing that's extremely tricky to do in the analytically correct & general case - if you can make any assumptions or approximations anywhere it will help a lot

[heady iris]

yeah

[mental rover]

but if you want to do what you're describing, it's almost certainly going to mean iterating over collider points in some way - either to check, or to construct a new one from the intersection

[cosmic rain]

I'd generate a density field(or whatever it's called) for each shape, intersect them and then do some vector math.🤔

[plain coyote]

well yeah, this is a common case, it can be easy or tricky depending on the shape.

Not sure if the unity standard colliders provide help or more complexity here

but basically , an Idea is to find the edges of intersection
I guess (not a proof but my mind is kinda telling me this could be correct)
one of the two vertices that define the edge is the closest point.
(this will fail if the point is within the radius of the circle that bounds the overlapped edge)

so your time required is 2 * number of edges * time_required_to_constructed an overlapped edge to find the point.

[heady iris]

What's the gameplay goal here?

[plain coyote]

is there a way to make a nuget package that only has
.net 6 version
to work with unity?
I am seeing only 4.8 being supported

[quartz folio]

No

[plain coyote]

🙃 there must be a workaround or something no?

[hollow hound]

I think can't rely on vertices not only if the point inside this radius, but if it's generally located between vertices on one axis

[hollow hound]

A weapon hitbox (can be static or moving) should be able to spawn entity (another hit box, for example) in the place of a hit.

[vagrant blade]

Find the nearest vertice, and determine the nearest adjacent. Then use math to find the intersection point between two lines

[late lion]

Since we're talking about geometry math...
I have a capsule (in 3D) that is intersecting with an infinite plane. How can I calculate the area of the intersection, as an axis aligned quad? Here's what it would look like, taken from the side and from the top. The red rectangle is what I want to calculate. The orange egg looking thing is the actual intersection shape, that I don't care about. I just need the bounding box around it.

I would also be satisfied with just the 2D version as a starting point. That would be the red line in the first picture.

[heady iris]

annoyingly, you can't get collision events between two kinematic rigidbody colliders

[swift falcon]

what could possibly be causing this jerking movement on the camera? if it's static or attached to the player directly everything works just fine

public class CameraController : MonoBehaviour
{
    public Camera mainCamera;
    public float lerpSpeed;

    private Vector3 position = new Vector3();

    void Update()
    {
        position.x = Mathf.Lerp(mainCamera.transform.position.x, transform.position.x, lerpSpeed);
        position.y = Mathf.Lerp(mainCamera.transform.position.y, transform.position.y, lerpSpeed);
        position.z = mainCamera.transform.position.z;
        mainCamera.transform.position = position;
    }
}

[heady iris]

fixedupdate vs update, I'm guessing

[swift falcon]

neither the player nor the camera have this snapping

hmm

[hollow hound]

I am very interested in this red line case too 😁

[heady iris]

is the player a rigidbody? if so, try putting Interpolate on

[swift falcon]

yeah I'm moving player in fixedupdate

thanks

that fixed it

[heady iris]

Interpolate does wind up making the object appear one frame behind where it should be, iirc

[swift falcon]

should've probably looked into the docs more

[heady iris]

https://docs.unity3d.com/ScriptReference/Rigidbody-interpolation.html

[swift falcon]

yeah I know what it does

[heady iris]

oh yeah, this actually explicitly talks about camera problems :p

also, cinemachine tends to Do The Right Thing

[swift falcon]

it just forcefully recalculated the graphic on every fixedupdate iirc

well, the graphic's position

[plain coyote]

good catch, I missed the simplest case,
but yeah then I think the only way if you want to measure the distances is to loop all edges
and find the standard
closest point on a line segment

if you have too many edges, group then into rects or circles and only choose the closest group (more like space partitioning)

[hollow hound]

The problem is, I need the point to be on the overlapped area perimeter. If I'll check every vertice, I'll get the blue point, not the green.

And even if only "affected" by collision lines would be checked, the nearest point on this line can be outside overlapping area : (

Oh, your proposal about grouping can solve this

[plain coyote]

I am not sure what you mean by perimeter?
how is the perimeter defined here? +
in linear algebra, you just clamp t of your direction vector to something between 0,1
so you get a point on the line segment

[hollow hound]

I mean surface of the overlapped area (blue here), don't know how to call it right 🙂

[regal epoch]

i have this txt file i want to use for my game. I want to import it into an array to be able to read every line individually. how would i do this. I had something working but found out this wasn't going to work on phones. right now i have
var txtFile = Resources.Load<TextAsset>("textfile");
this does read the file, but is not making it an array. how would i turn this into an array

[knotty sun]

split the text on newline

[regal epoch]

this seems to be working. thanks

[fallen epoch]

Hmmm... still struggling to get the game paused while I'm running a coroutine for some shader lerping.

Currently, I've got the coroutine which loops until the elapsed time is past my animation duration (the actual lerping only works because I'm yield returning some fraction of a real second at the end of every loop). I'm trying to "pause" the game by just making it run in a while loop for the same duration in real time (using unscaledDeltaTime).
I even tried setting a variable at the start of my coroutine and after the internal loop to try to handle "coroutine is currently running" but when I made a while loop based on that, it made an infinite loop. Frustrating.

Just found something that might help.
Storing the coroutine function as an IEnumerator and checking if .MoveNext() is true - if so it is running?

Nope, doesn't work so good for me :\

[placid mantle]

Why would I need to create an instance of a scriptable object, if scriptable objects aren't living things in the hierarchy?

Is that like instantiating a prefab?

[hexed pecan]

You can still create a new instance in the memory

It just depends on how you use your SO

Might not need it

[hollow hound]

I think more simple problem would be to find vertices of the overlap of two rectangles.
So only rectangles and just to find resulting shape.

Seems like this kind of problems more suitable for math.exchange, not for unity code-general. 😁

[placid mantle]

Ok thanks. I was watching a Unity video about them and saw the function and wondered why it would be used, I'll leave it for now. Thanks

[mental rover]

maybe, but in reality if this is a game mechanic you're trying to implement you can get something approximately good enough with a lot less effort - there were a few suggestions already that would do it

if you can say that the overlapping colliders will always be two rectangles it's immediately easier to solve

[strange jacinth]

Hey, can i get somehow list of collisions with points and normals from rigidbody? I tried using OnCollision events but I'm getting only last ContactPoint that it made.

[placid mantle]

I don't think I'm going to do anything super fancy with them. I've been exploring how to use them passing data across between scenes using delegates too.

I'm struggling a bit now because I dont want to use a singleton as I've heard they're not best practice but I can't seem to get my static class to subscribe to the delegates since they have no Awake or OnEnable function

How do you get static classes subscribed to delegates and events?

[latent latch]

singletons are fine

not likely to dig yourself a hole with them, unless you're using them across, say different characters. But for creating single type systems of management, such as object pools, they are fine.

[heady iris]

i don't like the phrase "not best practice"

it implies there is a Right Thing to do, and that everything else is a Wrong Thing

[placid mantle]

I need it to manage character data between scenes, and that data may change so will have a few functions on it too.

[placid mantle]

I've seen lots of videos where people talk them down so I assumed it was a beginner-friendly way of coding and there was better ways

As you can probably tell I'm very new to it all

[hollow hound]

Oh, I missed suggestions for alternative implementations? Or you mean not in this chat?

[heady iris]

Singletons can be a headache if you realize they're not so single after all

for example: in one game of mine (a ripoff of Alien: Isolation, more or less), I started with the assumption that there would be one enemy

and one player, too

so I had lots of code that just reference the single static monster and the single static player

then I realized that I want to have multiple players (mostly controlled by AI; it's not actually a multiplayer game)

so I had to rewrite a fair bit

now I'm thinking I want to have multiple enemies, too, and that's gonna be...a fair bit of rewriting

Although, that's not exactly the problem I was originally envisioning: that's a change from "one" to "many"

that's always going to be a some work

The big problem I can foresee with singletons is realizing that some actors need to refer to one thing, whilst others need to refer to another

you need to go from "they just read the singleton" to "someone hands them a reference"

[mental rover]

[12:08 PM]chemicalcrux: tbh, the most obvious solution to me is to do a batch of raycasts

[subtle herald]

Well... It implies there's a best thing to do and everything else is just not as good in some aspect, not that everything else is wrong entirely.

[heady iris]

they're bad practice (tm)

[mental rover]

I'd also have a read of this: https://xyproblem.info/
and think about whether this overlapping trigger thing you're trying to do is actually relevant to the problem you're trying to solve at all

[placid mantle]

Thanks @heady iris . Makes sense, for things that could grow I should look at alternative systems. But for something simple like a game-manager like I'm trying to create, its fine?

[subtle herald]

Again, not necessarily a wrong thing entirely though. But think what ya want. Time for work.

[heady iris]

Something with the "game manager" role makes sense as a singleton

there is a single manager for the game

[heady iris]

i am being sardonic here -- I agree that such things are not the "Wrong Thing"

some people get very dogmatic about this stuff

probably after overdosing on Clean Code

[hollow hound]

Well, the problem is "weapon hitboxes should spawn another entities in the position of the hit". If there a better approach I would be thankful for the advice.
Raycast thing can work, but seems a bit inefficient and it seems that there should be a better solution considering there are only rectanges

[placid mantle]

Thanks for the input guys. I'm gonna crack on and use a singleton, but I've learnt a bit more about static classes and scriptable objects in the process so thats a plus too.

[subtle herald]

Very, very true. Lol
This is also why I love programming. There's ALWAYS more than one way to do something.

[mental rover]

does it make sense that you need the point closest on the overlap, or should it just be whatever the centre of the weapon hits?

[plain coyote]

just to be sure are you looking for polygon-clipping?
have a look at the examples here:
https://www.tutorialandexample.com/polygon-clipping

if this is what you are looking for, then I am not sure if you unity does provide such support for those things, but in general you can google convex (hopefully your shapes are not concave) polygon clipping algorithm, they are a bit tough if you have not implemented one before.
Sad to say I don't think there is a simple way to do it, unless unity has an out of the box support using its built-in colliders (I think it is doable because the colliders are fixed in shape).

[hollow hound]

Weapons can be long,
With raycast there are still the problem that I need to know that point on cast overlap is in jitbox overlap.

[hollow hound]

Yeah, seems like I need to implement some of these algorithms.

[plain coyote]

before you do so

there is a possibility, this might help !

Thanks! I'll check it

[lone cape]

Hey, i created game, there is login where you put key and login to get access but question is can anyone read memory and hack it that we will pass that screen and play ?

And how i can project game

[potent sleet]

you use external server validations and use something like a bearer token

[lone cape]

I mean this screen sends req to my server and checks

But idk if they can just disable that screen and go on

[hexed pecan]

100% agree with this. Its a sign of closed-mindedness (is that a word?)

[potent sleet]

idk that depends on your implementation upon received data

you need to make a validation

[heady iris]

It's really wishy-washy

that's the part I don't like

it's vague Badness

[gray mural]

hey guys, how to reset all rigidbody factors in script?

I reset player's position and rotation when the game is over (when enemy hits player). Then I change timeScale for a while and player is still moving, because of the previous Ridigbody.AddForce

[heady iris]

You can also set the velocity to zero.

[gray mural]

just velocity?

[heady iris]

That’s the problem, isn’t it? :p

AddForce doesn’t “stick around”

[gray mural]

oh, sure, it works now, thank you

[hexed pecan]

Might wanna reset angularVelocity too

[hot torrent]

If i have multiple triggers on a gameobject and one of the attached script calls OnTriggerStay() wich of the colliders does it pick to check for collision?

[heady iris]

It's the other way around: one of the colliders caused OnTriggerStay to be called

I don't believe you can check which one it was.

[trim schooner]

If they're on the same GameObject or a child.. all of them

[heady iris]

If you have two different kinds of colliders, you should put them on two separate objects, and have scripts on each one to handle those colliders

[dull yarrow]

Is possible to create a scriptable object with another script in it?
For example i am creating a scriptable object called item with itemType, itemImage, etc
And i want that object to have another script in it, for exemple itemStats, with another set of variables

Then i have a problem where only one of em calls the method!

[hot torrent]

I think you have to do Public <Class> Name;

[astral edge]

is it possible to create a script that automatically resizes imported imaages of a specific extension, they are auto resized? Would this work?

`using UnityEngine;
using UnityEditor;

public class ImageResizer : AssetPostprocessor {

void OnPostprocessTexture(Texture2D texture) {
    // Check if the imported asset is a texture
    if (assetPath.EndsWith(".png") || assetPath.EndsWith(".jpg") || assetPath.EndsWith(".jpeg")) {
        // Resize the texture to 1024x1024 pixels
        TextureScale.Bilinear(texture, 1024, 1024);
        // Save the resized texture to a new file
        byte[] bytes = texture.EncodeToPNG();
        File.WriteAllBytes(assetPath, bytes);
        AssetDatabase.ImportAsset(assetPath);
    }
}

}`

I'm not super savvy with coding

[heady iris]

do you want to change the maximum size of the image asset?

[astral edge]

Yeah, I'd like to set that so they all import at 1024 by default, and I can adjust some accordingly.

[trim schooner]

physics events will also only be picked up by 1 component on a gameobject/ children

[hot torrent]

Does a the OnTriggerStay method count as physics?

[trim schooner]

of course

[hot torrent]

hm

[dull yarrow]

And that object will get the script inside of it?

[hot torrent]

how do i decide wich of the colliders gets used for that?

[hot torrent]

i think you drag and drop it onto the scriptable object or select it inside the Editor

[trim schooner]

You can't via code afaik. You have to setup your hierarchy how you want.

OR

You make your own physics events, so you only have 1 component listening to the physics events.. and then everything else listens to your custom physics events

[hot torrent]

i imagine it like this!

this is inside the scriptable object's code

[heady iris]

note that I would not say it "gets the script"

if you have a serializable type called Foo, you can make a field of type Foo

public class Bar : ScriptableObject {
  public Foo foo;
}

you can assign an instance of Foo to that field

if Foo is also a ScriptableObject, then you can create an asset that holds a Foo and assign it to the field on a Bar

[hot torrent]

eh?... i have no idea how to do that...
What if i place the other collider in the parent? would the collider call the OnTriggerStay method from the parent aswell?

[heady iris]

the collider sends the message to components on its own game object

also, if you have a Rigidbody on a parent object, it will receive collision events for its child colliders

[hot torrent]

isn`t a rigidbody necesary if i want trigger collision checks?

[trim schooner]

only on one of the colliding objects

[hot torrent]

so i don't have to put it on the trigger object?

[trim schooner]

If the object(s) you expect to hit the trigger has a rigidbody.. then no, the trigger doesn't need it

[hot torrent]

but the object that is the trigger is actively moving...

[trim schooner]

There could be a case where the objects hitting the trigger don't have rigidbodies, so you would put the rigidbody on the trigger

sigh

Only ONE of the colliding objects REQUIRES a rigidbody for the collisions to work, more than one rigidbody is fine, in the cases that they're required

[hot torrent]

i get that!

ok i think i have an idea for a solution brb

[gray mural]

is the any way to do lambda "equals" in C#?
like that:

int num = (condition) ? 1 : 2; // that's default one

int num = 
{
  if (condition) return 1;
  return 2;
};

[leaden ice]

not sure I understand the question

Do you mean a switch expression?

[solemn rune]

Hya. I'm trying to drag and drop drawn rects in the inspector (custom editor script). I have a (background) rect (rect0) made with GUILayoutUtility, and used with GUI.BeginClip, within which all the dragging action should take place. Then I draw a tiny rect with EditorGUI.Drawrect (rect1). I am able to detect clicks in rect0 ( with if rect0.Contains(currentmousePosition), but I cant use the same on my tiny, draggable rect1. if (rect1.Contains(current.mousePosition) never fires.. Anyone any idea?

[steady moat]

https://docs.unity3d.com/ScriptReference/AssetPostprocessor.html
https://docs.unity3d.com/ScriptReference/AssetPostprocessor.OnPostprocessTexture.html

[solemn rune]

public override void OnInspectorGUI()
{
    DrawDefaultInspector();

    Rect rect = GUILayoutUtility.GetRect(0, 1000, 200, 200);

    GUI.BeginClip(rect);

    Rect rectP1 = new Rect(bez.p1.x, bez.p1.y, 10, 10);


    EditorGUI.DrawRect(rectP1, Color.red);


    GUI.EndClip();

   
    Event current = Event.current;
    bool wasMouseDown = false;

    if (rect.Contains(current.mousePosition))
    {
        if (Event.current.type == EventType.MouseDown && Event.current.button == 0)
        {
            Debug.Log("Left-Mouse Down");

            if (rectP1GUI.Contains(current.mousePosition))
            {
                Debug.Log("clicked in rectangle 1");
            }
    }

}

[gray mural]

like that one:

int[] nums = new[] { 1, 2, 3, 4, 5 };

nums.Select(n => n % 2 == 0 ? n : n + 1); non-lambda

// lambda
nums.Select(n =>
{
// do smth

if (n % 2 == 0) return n;
return n + 1;
});

[leaden ice]

nums.Select(n => n % 2 == 0 ? n : n + 1); non-lambda
This is a lambda

why are you saying it's non-lambda

[gray mural]

not mean not "big lambda"

[steady moat]

This is a ternary operation. https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/conditional-operator

[leaden ice]

I don't understand the question.

Are you asking how to write a lambda with multiple lines?

instead of a lmabda expression?

[gray mural]

I am asking if there is a way to "equal" a variable to the lambda

[leaden ice]

Yes that's called a delegate

Func<bool> myDel = () => true;```

[gray mural]

we can do this:

bla = (bla % 2 == 0) ? bla : bla + 1;

but cannot do this:

bla =
{
  if (bla % 2 == 0) return bla;
  return bla + 1;
};

[leaden ice]

Func<int> myLambda = n => n % 2 == 0 ? n : n + 1;
var result = nums.Select(myLambda);```

[gray mural]

without additional function?🤔

[leaden ice]

there is no additional function

Func<int> is just a delegate type

Func<int, int> myLambda = n => {
    return n % 2 == 0 ? n : n + 1;
};```
Here it is again without compile errors

Func<int, int> means "a function that accepts an int parameter and returns an int"

[gray mural]

ok, thank you, I guess it's impossible to do what I wanted in C#

[leaden ice]

No I think it's totally possible

[heady iris]

I still have no idea what you're asking about

[leaden ice]

aand I've showed you how to do it

and you don't like it

🤣

[heady iris]

you can literally just Do It

[gray mural]

I do like it

[leaden ice]

Maybe you don't like the word "Func"

We can do it without the word Func

public delegate int MyCustomDelegate(int param);

void Example() {
  MyCustomDelegate ex = n => {
    return n % 2 == 0 ? n : n + 1;
  };
  var results = myArray.Select(ex);
}```

[heady iris]

this appears to be entirely a matter of syntax

you can't write it that way, because that's not how the C# syntax works

[heady iris]

but you can write it this way

[gray mural]

I have understood that now

[gray mural]

ok, thx

the next question then: Is it nice to do smth like that in Unity?

private readonly (((float min, float max) neg, (float min, float max) pos) x, float y, ((float min, float max) neg, (float min, float max) pos) z) spawnPos = (((-13, -6), (6, 13)), .09263992f, ((-11, -6), (6, 11)));

[heady iris]

i'm scared

[leaden ice]

this isn't a unity question

it's a C# question

and C# does have tuples

[gray mural]

Unity

[leaden ice]

if you are feeling Masochistic, you can certainly use tuples

[heady iris]

is that tuple syntax?

i haven't actually tried doing that before

[leaden ice]

but I recommend just making an actual struct

[heady iris]

yeah

[leaden ice]

no this is not valid syntax

[gray mural]

I know, but it is spawn for Unity

[gray mural]

yes

[heady iris]

everything would be a Unity question by that criteria

how do I install Windows (so that i can run unity)

[gray mural]

nop, that one was certainly unity question

[steady moat]

No, this is what we call Primitive Obsession.

[gray mural]

it hurts

[gray mural]

doesn't this tuple looks quite nice?

[heady iris]

it looks like a struct that got run over by a train

[steady moat]

No. This is unreadable and unmaintainable.

[gray mural]

should I really do it in struct then?

[leaden ice]

just make structured/named structs and do it that way so you don't want to kill yourself to read the code

[steady moat]

Yes

[heady iris]

it's all basically the same thing to the computer

[gray mural]

that's the answer!

[steady moat]

Programmer are not computer unfortunately.

[plain coyote]

so , I decided to take a leap of faith and try my luck at compiling a .net6 library to 4.8 framework, to use it inside unity.

Any general tips so I can ensure my compatibility with unity?
or is it generally speaking, if it runs under 4.8 framework, it will run in unity?

Why I can't store AttractorData[] AttractorStructs; I try NativeArray but there's error : BallData used in NativeArray<BallData> must be unmanaged (contain no managed types) and cannot itself be a native container type.

    public int Identifier;

[rain coral]

Hello I’m trying to make a mechanic in the game where I can command troops from 1-20 with formations but I don’t know where to start

[warm stratus]

hey, i have a problem to get the audio sources on a gameObject (it is a prefab maybe it is the problem)
AudioSource[] audioSources = GetComponents<AudioSource>();

[fallen epoch]

I assume that script's on the same game object as the AudioSources?
Did you try replacing AudioSource[] with var? 😛

[knotty sun]

what is the problem? Show the inspector of the gameObject

[warm stratus]

there is an inspector for each game object ???

[knotty sun]

of course there is Unity 101 basics, you should know this

[warm stratus]

a...

[fallen epoch]

In the default UI layout, when you have a game object selected, it's on the right hand side of the screen

[warm stratus]

somewhere here?

[fallen epoch]

That entire window is the inspector 😅

[knotty sun]

no, the whole inspector for the complete game0bject

[fallen epoch]

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

[knotty sun]

how can you not know this, you added AudioSources to an object did you not

[warm stratus]

the script add audio Source

[knotty sun]

well if the script added them why do you need GetComponents?

[late lion]

You cannot use managed arrays in jobs, you have to use NativeArray. But also, you can't have nested NativeArrays, which it looks like you're trying to do.

[plain moon]

Yes. In each ballData contains Attractor info and count of it can be greater than 1. And I want to know how I can store it

[warm stratus]

i use GetComponents to add them into a list which each frame low the volume of each element to smoothly stop the sounds between scenes

@knotty sun

[rugged storm]

Hay im making a turn based game and the enemy turns are not very computationally heavy so they end up happening almost instantly and all the enemies move at basically the same time, how would I go about slowing this down so it looks a little nicer and stuff?

[late lion]

You could store all the attractors in one combined array and store a index range in BallData so you know where to read from the combined array. You could also use NativeMultiHashMap to create a hashmap of BallData to multiple attractors.

[knotty sun]

you are missing my point. If you add the AudioSource components in script you alreasy have a reference to add to your list, you dont need to use GetComponents

[warm stratus]

ok i will try

thanks

[plain moon]

I love first option 😄

[warm stratus]

but i still don t understand why it don t work

[rugged storm]

in my script I basically go through enemy.TurnLogic(); for each enemy during thier turn is there a way i could wait until say the movement animation of one enemy is done before the next one's turn

[knotty sun]

you still have not explained what you mean by 'don't work'

[warm stratus]

there is 1 audioSource on the gameObject, and when i use GetComponents i get 0 audioSources

[knotty sun]

ok. So show the inspector of this gameobject in play mode once the audiosource has been added

[violet mesa]

Does anybody know how to get a bullet list in textmeshpro?

[gray mural]

what?

[wide terrace]

I would think to create a queue of movement coroutines, then maybe use a second coroutine which would pop a movement off the stack, execute it and wait for it to finish, and repeat until the queue is empty. That way you could calculate all of your movements ahead of time and easily determine when all are complete.

[swift falcon]

Plz could anyone tell me if there is an error unity keep saying that "skull" could not be found

public class Area : MonoBehaviour
{
public skull[] enemyArray;

private void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.CompareTag("Player"))
    {
        foreach (skull enemy in enemyArray)
        {
            enemy.chase = true;
        }
    }
}

[violet mesa]

something like this

[gray mural]

you mean the array of TextMeshPro?
[SerializeField] private TextMeshPro[] texts;

[knotty sun]

do you have a script and class called skull?

[hexed pecan]

Bullet list is those dots on the left

[swift falcon]

no

[knotty sun]

well what do you expect then? Magic?

[violet mesa]

i basically want a dot (bullet) before every new line
