[wooden cove]

quite randomly I might add

or at least it feels as such

[quartz folio]

is it based on where you look

[fluid lily]

That sounds like some scripting thing, unless you are saying just visually disappearing. Try changing the shader on the object, other wise there are a few tools you can use to find all references to the object being used.

[wooden cove]

it might be, its hard to say what the exact cause is because we have very little info to go on

[quartz folio]

Have you checked the bounding box of your object?

If you're positioning it via shaders for example, then the bounding box isn't where the mesh is

[wooden cove]

you think the object might be considered outside the frustum?

[quartz folio]

so it'll disappear when you stop looking where the mesh is actually positioned

[wooden cove]

we are not using shaders to manipulate the geometry in any way

[quartz folio]

this can also happen with animated objects, sometimes you have to set them to not be culled or recalculate their bounds

[wooden cove]

the objects are also not animated

they are static meshes that are placed on an AR plane

each only has a few materials, with a default lit shader

[quartz folio]

No idea then, I can only imagine it's an AR-specific issue

[fluid lily]

culling could be an issue, why I was thinking if it is some custom shader on the object, though would seem like it would be consistent unless something is really going wronge with it.

[wooden cove]

it's very likely that it is, as it never happens in the editor no matter how much we move around and try to make it happen

[fluid lily]

Another aproach would be make a empty scene with that object and a camera. At this point you will probably just have to track down one thing at a time.

[wooden cove]

I figured as much. We are looking at the code to see if some event is firing without our knowledge.

[fluid lily]

Is there like a big game jam or something going on, begginer is exploding?

[wraith knot]

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

public class dapipe_script : MonoBehaviour
{
    public float movespeed=5;
    public float deadzone = -30;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.position += (Vector3.left * movespeed) * Time.deltaTime; 

        if (transfrom.position.x < deadzone)
        {
            Destroy(gameObject);
        }
    }
}

i need help with this

the if statement is not working

[wooden cove]

I don't know about any big jam going on. This is my actual work project

[fleet furnace]

#💻┃code-beginner
Maybe try attaching a debugger and try fixing it on your own.

[wraith knot]

how can i

im new here

[wraith knot]

?

[fleet furnace]

I hope your Visual Studio is setup properly. You can find more information there: #854851968446365696

[unreal temple]

If an artist has set a serialized color field to a color, and we want to convert that value to HDR, how can I do this?

I'm assuming that adding the ColorUsageAttribute will not reserialize the value.

(I'm assuming the data is interpreted differently for HDR, I don't know much abou this, just that the colors are rendering wrong)

[quartz folio]

It's fine, LDR and HDR values overlap the same

At least, I thought they did

[unreal temple]

Right, so HDR just extends beyond 1 for RBB?

Our issue is that when I set the colors in a VFX graph they're wrong.

https://cdn.discordapp.com/attachments/1047651896980152450/1082541613034786836/image.png

So the lines of color overlayed (red+blue, yellow+red) are fromt he inspector

They're setting the colors in the bullets, which are much paler than in the inspector.

But when we set those colors in the VFX graph inspector they are true to the serialized value.

[quartz folio]

It could be a blending issue, post processing, or... a linear vs gamma problem

[unreal temple]

Maybe linear vs gamma

woudl be my guess

But they're just Color values right?

Or maybe the fields in the VFX graph are special in some way

[quartz folio]

It's all affected by that nonsense, and there has been issues in the past https://issuetracker.unity3d.com/issues/color-color-fields-except-gradients-in-the-vfx-graph-are-in-gamma-color-space

[unreal temple]

Hm. we're on version 13.1.8

But that does seem like the problem.

Okay, I'll try converting the value to linear space?

or... gamma space

lol I'm in over my head

I'll try both ways and see which works

[quartz folio]

That's what I try

Every time there's a colour issue I'm there with the conversions just to check

[unreal temple]

haha, yeah when we changed the project to linear space everything became pastel

So I'm guessing it's gamma being read as linear

Thanks @quartz folio ❤️

[violet cipher]

I keep having an error with a ?: operator

`public class Movement : MonoBehaviour
{
private Rigidbody2D rb;
public float moveSpeed;
public float rbacceleration = 7;
public float rbdecceleration = 7;
private bool facingRight = true;
public float velPower;
public int moveInput = 0;

// Start is called before the first frame update
void Start()
{
    rb = GetComponent<Rigidbody2D>();
}

// Update is called once per frame
void Update()
{
    if (Input.GetKey(KeyCode.D))
    {
        moveInput = 1;
    }
    else if (Input.GetKey(KeyCode.A))
    {
        moveInput = -1;
    }

    if (Input.GetKeyUp(KeyCode.D))
    {
        moveInput = 0;
    }
    else if (Input.GetKeyUp(KeyCode.A))
    {
        moveInput = 0;
    }

    //calculate the direction we want to move in and our desired velocity
    float targetSpeed = moveInput * moveSpeed;
    //calculate difference between current velocity and desired velocity
    float speedDif = targetSpeed - rb.velocity.x;
    //Calculate if our moveInput is 0 it will de accelerate, anything higher than 00.1 will make us accelerate
    float accelRate = (Mathf.Abs(targetSpeed) > 0,01f) ? rbacceleration : rbdecceleration;`

I get the error: Cannot implicitly convert type '(bool, float)' to 'bool'

but im not converting a bool to a float as far as i checked

rbacceleration & rbdecceleration both have a float value of 7

so accelrate should be 7 then

it's very confusing to me

[knotty sun]

Mathf.Abs(targetSpeed) > 0,01f

should be 0.01f

[violet cipher]

wow...

i feel so dumb rn

Thank you so much btw

[unreal temple]

boom

[orchid bane]

Is there a collection like Dictionary but which allows to get values the other way around too?

collection[a] //returns b
collection[b] //returns a```

Something like this

[unreal temple]

No, if you need that you'll need to keep two dictionaries in sync

Although... there may be another solution

What is the type of the dictionary?

[orchid bane]

I don't really need multiple values to the same key, only 1

A reference type

[unreal temple]

?

I mean what types are key + value

Both the same type?

[orchid bane]

Yeah

[cosmic rain]

I don't think there's an existing solution for that, but you could implement it yourself.🤷‍♂️

[unreal temple]

Then just enter everything twice.

[cosmic rain]

That could work👆

[unreal temple]

Potenitally you could do this too

HashSet<(MyType, MyType)> _set;

But that's only if you want to check if the connection exists

If you want to actually retrieve the other value just enter everything twice.

So like:

void LinkTheseThings(Foo a, Foo b) {
  collection[a] = b;
  collection[b] = a;
}

void RemoveThisThing(Foo a) {
  if (collection.TryGetValue(a, out var b)) {
    collection.Remove(b);
  }
  collection.Remove(a);
}

[orchid bane]

HashSet will do, thank you

[summer nebula]

what.. is a hashset

[unreal temple]

The problem is you need some way of sorting them

It's easy with integers etc

But the hashset needs to have the keys in a predictable order

For example:

bool LinkExists(int a, int b) {
  (int, int) key = Sort(a, b);
  return _hashSet.Contains(key);
}

It's a bit harder with references

[orchid bane]

Then will have to think about something else

[unreal temple]

I might have an idea if you have the use case

and you want it

[orchid bane]

Well

I have nodes

Like these ones

[unreal temple]

Ah cool, so these are the eges?

[orchid bane]

And I'm trying to create the trails properly

[cosmic rain]

Oh I almost got that job on upwork😭

Well, it wasn't that great to be honest.

[unreal temple]

Hey don't shit on telov

[orchid bane]

So I thought of starting with a random node and then going all over its connections creating trails

Meanwhile storing the created pairs so that I do not create duplicates

That's what I'm trying to do

[cosmic rain]

Just create a Node class with a list of Nodes

[unreal temple]

Yeah, I'd probably do that too.

Easiest for recursion

class Node {
  List<Node> _edges;
}

[orchid bane]

I have this for now

public class Node : MonoBehaviour
{
    [SerializeField] public List<Node> connections;

    private void OnValidate()
    {
        foreach (var node in connections)
        {
            if (!node.connections.Contains(this))
            {
                node.connections.Add(this);
            }
        }
    }
}```

[unreal temple]

well then you don't need a dictionary

You can just do:

if (node.Connections.Contains(otherNode)) {

[orchid bane]

But they both have each other

[cosmic rain]

So what?

[unreal temple]

yeah, that's right.

A graph is like a doubly linked list

If A -> B but B is not connected to A then it means you can move from a to B, but not from B to A

In this example everything is doubly linked

Alternatively you can give each node an ID and then use the HashSet example from above

I would consider that option

Just make sure that all the nodes are created with a unique ID

If you have an array of nodes it can be their index

But there's nothing wrong with this:

static void Link(Node a, Node b) {
  if (!a._connections.Contains(b)) a._connections.Add(b);
  if (!b._connections.Contains(a)) b._connections.Add(a);
}

[orchid bane]

I'll just create a recursion I guess

[solemn prism]

Hello guys Iam making a vr project for school and iam trying to make objects have an outline when you touch them but I can't find anything on it online is there anyone here that could help me?

[orchid bane]

search for outline shader

[solemn prism]

I have and everything I'm finding on it is either for mouse and keyboard not vr or has the object highlight always not only on hover enter

[thin aurora]

Ask in #archived-shaders

[fiery oracle]

This article mentions that you shouldn't use occlusion culling for outdoors, is that correct? https://thegamedev.guru/unity-performance/occlusion-culling-tutorial/?utm_source=youtube&utm_medium=video&utm_campaign=occlusion_culling

[cosmic rain]

Depends on the outdoors, but generally, yes

[fiery oracle]

What do they mean by "(occlusion areas) These areas are typically where the camera can go through."

[craggy veldt]

each node should have two ports, e.g: output and input, this way it would be very easy to sort things out
and those ports can accept multiple inputs/outputs from multiple nodes. Similar to GraphView api

[fiery oracle]

More specifically, how do you decide where to set the occlusion area?

[cosmic rain]

You need to bake the occlusion data.

[fiery oracle]

I mean manually setting the box area. How do you decide the bounds of each occlussion area box?

[cosmic rain]

An occlusion area is an area of interest where we want to bake occlusion culling at a higher precision:

Areas closest to the player

https://docs.unity3d.com/Manual/class-OcclusionArea.html

unity docs do a better job at explaining

[rustic ember]

I want GridPos2D to be like the Vector2, just with integers. How can I make x and y show in the inspector?

[somber nacelle]

you know Vector2Int exists already, right?

[rustic ember]

Ummmm, no?

You are a literal life saver. For years I had no idea 🙃

[somber nacelle]

Well now you do!
Also in regards to the issue you presented, as long as you have a serialized field of type GridPos2D it will show in the inspector

[rustic ember]

Great. Thank you

[snow moat]

Hello,
I used the localization package
But when I have a "\n" in my localized string, we see these on the screens.
How can I add newline in my localization ?
Thx in advance

[lost wave]

when switching from level two to level three, an animator controller for the transition fade, deletes from the inspector. it works fine from level 1 to 2.

[crude mortar]

it turns it into a toggle button where the float will be 1 or 0 depending on the toggle state

[placid summit]

Anyone use git source control and how do you manage large binary files (LFS support)?

is it fine 'out of the box'?

[celest moss]

Hey is there a best practice for handling the communication between multiple Managers?

[cosmic rain]

One manager to rule them all🤔

[molten sandal]

Question:

Given this piece of code:

RaycastHit hit;

trackDetected = Physics.SphereCast(transform.position, sphereRadius, transform.TransformDirection(-Vector3.up), out hit, rayDistance, layerMask);

Vector3 normal = hit.normal;

Is hit.normal in world space or in local space?

[crude mortar]

it is always the world space normal

[molten sandal]

kk, thanks

and hit.point? also world space?

[crude mortar]

yes

[thick socket]

how does the 2nd shorter version of this error but not the first 2 liner?

[leaden ice]

because it's a property

colorOverLifetime is a property and it's a struct

so you'd only be modifying a copy

strangely enough, the way Unity implemented the particle system modules this wouldn't actually be an issue - but C# doesn't allow it to prevent potential bugs

[thick socket]

gotcha

the piece I don't follow is how setting it to a variable then setting color works

yet making it all in 1 line doesnt

[leaden ice]

because C# doesn't want to let you do it if you don't have the ColorOverLifetimeMpodule saved in a variable

because it doesn't want you to lose the changes

[thick socket]

gotcha thanks

[leaden ice]

but again, since Unity implemented these structs in a weird way, it wouldn't actually be an issue like it normally would

[thin aurora]

Considering it's a struct, hence value type, the first two lines won't work either

[leaden ice]

for example for a Vector3 this would be an issue

[leaden ice]

They will actually.

[thick socket]

https://docs.unity3d.com/ScriptReference/ParticleSystem-colorOverLifetime.html

its what the unity doc says to do

¯_(ツ)_/¯

[leaden ice]

Unity implemented the structs this way

[thin aurora]

Unity changed the way structs work?

[leaden ice]

color is a property that actually sets the native data properly

[thin aurora]

Lol this engine

[leaden ice]

it's not a change in how structs work

it's a property, not a field

[thin aurora]

They made it so complicated

[leaden ice]

yes

they should have just done it normally, but Unity is Unity 😆

I think they thought they were simplifying it

[late lion]

What would have been the normal way?

[leaden ice]

requiring you to write the struct back to the particle system

item.colorOverLifetime = col; (after making your changes)

[thick socket]

that would have made more sense in my mind lol

NullReferenceException: Do not create your own module instances, get them from a ParticleSystem instance

void SetParticleColors(bool isDefault)
    {
        Gradient grad = new();
        RarityColors rColors = new();
        //item
        if (isDefault)
        {
            grad.SetKeys(
            new GradientColorKey[] { new GradientColorKey(Color.white, 0.0f), new GradientColorKey(new Color(0.00392f, 0.20784f, 0.30980f), 0.6f) },
            new GradientAlphaKey[] { new GradientAlphaKey(0.0f, 0.0f), new GradientAlphaKey(0.6f, 0.13f),
                new GradientAlphaKey(0.6f, 0.83f), new GradientAlphaKey(0.0f, 1.0f) });
        }

        foreach (var item in allParticles)
        {
            var col = item.colorOverLifetime;
            col.color = grad;
        }
    }```

its getting mad at me for the col.color = grad;

Im not sure why...I followed the unity documentation for it

[leaden ice]

what is allParticles?

[thick socket]

allParticles = new List<ParticleSystem> { particles, particlec1, particlec2, particlec3, particlec4 };

ah dang, looks like I missed serializing one in editor

[late lion]

Oops, that would be because Unity's fake null object in the editor. Instead of assigning null, Unity will assign an object that is supposed to throw a "MissingReferenceException" if any of its properties or methods are accessed, but I guess they forgot to do that for ParticleSystem modules.

[pure flint]

Hi im new here so I dont know if this is the right channel to ask how to code specific thing but here goes.
So I made a List/Array. And I want to Instantiate those game objects and I did it. It worked BUT I want it to instantiate limitly for example
Gameobject A, B, C, D
so I want to instantiate gameobject A and B from the array/list without game obeject C and D being instantiated.

[marble cove]

Hello idk if this is to place to ask, but idk what to do, i have a script called item, whenever a gameobject with this script becames a child its stops updating, the script remains enabled but it stops updating(the gameobject is active too), what is this? how can i fix it?

[leaden ice]

So only instantiate the first two.

[leaden ice]

As long as it's enabled and active, it will continue to update. Did you make a child of a deactivated object perhaps?

[pure flint]

yes. cause Im making like random spawner. I just want it to spawn 3 things out of the array/list

[leaden ice]

Use a for loop with a limit of 3

[marble cove]

nooo i checked, its still active when it becomes a child

[leaden ice]

for (int i = 0; i < 3; i++) {
  ...
}```

[leaden ice]

then it will update

Share details if you're still confused

[marble cove]

but it doesnt

okay

[leaden ice]

prove it

[pure flint]

will try that

It works thank you. I dont know why I didn't think of it

[marble cove]

i have this script as you see there is a print that should be alway print "!" but when i make the object a child it stops

and you can see it here that its enabled

and nothing happens it just stops updating

[leaden ice]

show what you made it a dchild of

show the hierarchy when it stops

etc

also you really should not be doing FindObjectOfType in Update - let alone multiple times. But that's a separate discussion

[marble cove]

the player is the root

[leaden ice]

and show the inspector for Crucifix, as well as the console window

[marble cove]

i know its just some test code i was tryna do to solve this bug

it stopeed after 4

because thats when i picked it up

[leaden ice]

The script in question is Item?

[marble cove]

yes

[leaden ice]

Based on what you showed - it shouldn't stop updating. What happens if you restart Unity?

[marble cove]

let me try it, but in my understanding that shouldnt change anything cuz unity compiles the game every time i hit play and that should fix an error like this

[leaden ice]

Nothing should stop Update as long as the GameObject is active and the component is enabled

[marble cove]

it stops after restart too 🥲

[marble cove]

i know thats why i asked you guys here on dc

i work in unity for a good time now and i never see something like this

[leaden ice]

Nor have I 🤔

[marble cove]

and the funnier that this is an lts version of unity so it should popped up before

and the even funnier bit that when i unchild the item object it continues updating

[leaden ice]

silly question but can I see the pickup or waepon slot code or whatever

maybe it's deactivating and reactivating the item every frame or something

that could interrupt Update

[marble cove]

it just one call when the player pressed pickup

[leaden ice]

how do you handle activating and deactivating the hands_n objects?

[marble cove]

this code runs when something happens that sould change the hand sprite, then it stores the current index of that sprite in the "righthand" variable

[leaden ice]

there we go

exactly what I was thinking

you're deactivating them all in that loop

for (int i = 0; i < Hands.GetChild(0).childCount; i++) {
  Hands.GetChild(0).GetChild(i).gameObject.SetActive(i == r);
  Hands.GetChild(1).GetChild(i).gameObject.SetActive(i == l);
}```
Try replacing the loop and the two lines after it with this ^

Right now you're deactivating then reactivating each frame probably. So it appears always active in the inspector/hierarchy, but you're not letting Update run.

[marble cove]

i fooouuund the problem thanks to your idea of something disrupting the update, it was an else if, that should be just an if

thank you very much!

[coral kettle]

does anyone know if a quick way exists to make the values of 1 script match another of do I need to 1 by 1 copy them over?

2 difference instances of the same script

[knotty sun]

copy/paste values in inspector

[coral kettle]

I mean in code

at runtime

[pearl swallow]

if (plantIndex == 0)
        {
            transform.position = new Vector3 (tunnelArray[0].transform.position.x, tunnelArray[0].transform.position.y-10, tunnelArray[0].transform.position.z);
        }

So I'm trying to have a GameObject move down in y value by a certain value. I've tried other versions of it, to no success. I've had done it before, but now I'm not sure why it is no longer working.

Wait-

[knotty sun]

simple way is to serialize/deserialize, not that I would recommend this, you could also use Reflection

[pearl swallow]

Would I just subtract it by not including the tunnel array part?

[ocean quail]

If you aren't updating tunnelArray, whatever that is, then yeah, you're just setting it to the same value-10 over and over again

[pearl swallow]

The array has a certain number of empty GameObjects that do not change actively, it's a list of transform values.

[ocean quail]

Is each element supposed to represent an offset?

[pearl swallow]

It is supposed to represent a new position that the GameObject moves to when the PlantIndex, which is a random), adjusts accordingly.

It's just in a certain instance of the code, it is supposed to move down by 10 until I can get an animation done for the object.

It's meant to be a placeholder code to represent what the animation is supposed to do.

It moves to the positions just fine.

I just can't subtract the Y value.

From the y value*

[ocean quail]

There's nothing wrong with that code, assuming index is 0 it should be set to Tunnel0-10. I would make sure 100% that that code is running, and furthermore that something else isn't resetting the position back to something else.

[pearl swallow]

transform.position = tunnelArray[0].transform.position;

This is in the start method but that shouldn't do anything but set up the initial.

Another section has it move back into the regular position (no subtraction to Y), but that wouldn't be called unless the other if statement in the update method had the parameters set.

[leaden ice]

you need to show the (full) code and explain the desired behavior. Right now we just have little bits and pieces and not the whole picture of what you're doing

[pearl swallow]

   public void PlantTunnel()
    {
        plantIndex = Random.Range(0, 3);
        plantStatus = 1;

        if (plantIndex == 0)
        {
            transform.position = new Vector3 (tunnelArray[0].transform.position.x, tunnelArray[0].transform.position.y-10, tunnelArray[0].transform.position.z);
        }

        else if(plantIndex == 1)
        {
            transform.position = new Vector3(tunnelArray[1].transform.position.x, tunnelArray[1].transform.position.y - 10, tunnelArray[1].transform.position.z);
        }
        else if (plantIndex == 2)
        {
            transform.position = new Vector3(tunnelArray[2].transform.position.x, tunnelArray[2].transform.position.y - 10, tunnelArray[2].transform.position.z);
        }

        else
        {
            transform.position = new Vector3(tunnelArray[3].transform.position.x, tunnelArray[3].transform.position.y - 10, tunnelArray[3].transform.position.z); ;
        }

    }

[leaden ice]

why would you write it this way 😱

transform.position = new Vector3 (tunnelArray[plantIndex].transform.position.x, tunnelArray[plantIndex].transform.position.y-10, tunnelArray[plantIndex].transform.position.z);```

this replaces ALL of those if/else blocks

[crude mortar]

also Random.Range is exclusive, so it will never choose the final array element

[pearl swallow]

I was following stuff from google and etc.

I try to use that before going to here.

Which I should stop doing since this is a valuable resource.

[crude mortar]

arrays exist to avoid this exact kind of repeated code, for future reference

[pearl swallow]

Huh

Thanks

[leaden ice]

If you ever find yourself explicitly writing a number in like someArray[1] you should stop and think - you're probably doing something wrong

it should almost always be a variable

likewise if you're repeating the same code for different indices

[pearl swallow]

I don't really mess around with arrays too often, so I'm not knowledgable in them.

[leaden ice]

Also a somewhat less verbose (and more performant) way to do this:

transform.position = tunnelArray[plantIndex].position + new Vector3(0, -10, 0);```

[pearl swallow]

Thanks

public void PlantUntunnel()
    {
        transform.position = tunnelArray[plantIndex].transform.position;
    }

So for this method, it should just move it to the original position of whatever tunnel has been selected?

I adjusted it to match what you gave me.

[crude mortar]

assuming the position of whatever is in the tunnelArray isn't changing, then that sounds correct

[pearl swallow]

Well, it didn't...

Lemme copy the rest.

    void Start()
    {
        transform.position = tunnelArray[0].transform.position;
        plantStatus = 0;

        navMeshAgent = GetComponent<NavMeshAgent>();
    }

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

        //Creates a tunneling system for the Plant based on time.
        plantTime += Time.deltaTime * plantInSeconds;

        if (plantStatus == 0 && plantTime >= 10)
        {
            PlantTunnel();
            plantTime = 0;
        }

        if (plantStatus == 1 && plantTime >= 5)
        {
            PlantUntunnel();
            plantTime = 0;
        }

        if (plantStatus == 2 && plantTime >= 2)
        {
            plantStatus = 0;
            plantTime = 0;
        }

        //Sets distance from player for shooting or biting.
        playerDistance = Vector3.Distance(player.position, transform.position);

        if(playerDistance <= plantRange && plantStatus == 0)
        {
            transform.LookAt(new Vector3(player.position.x, transform.position.y, player.position.z));

            if (fireCountdown <= 0f)
            {
                GameObject poison = Instantiate(poisonProj, poisonSpot.position, transform.rotation);
                poison.GetComponent<Rigidbody>().AddRelativeForce(Vector3.forward*500);

                fireCountdown = 10f / fireRate;
            }
            fireCountdown -= Time.deltaTime;
        }
        
    }

This is the rest minus anything above start.

[crude mortar]

where are you changing plantStatus now?

[leaden ice]

Use a paste site and share the whole script 🙏

[crude mortar]

when preator said that his code replaced all the if statements, I think you accidentally removed that as well

[pearl swallow]

https://pastebin.com/LuebWMR1

[chrome thistle]

When I transition to another camera, there is a little delay where do I remove that? Timeline with cinemachine!

[pearl swallow]

Second index was removed because it was causing conflicts, basically my attempt to do a non-repeating random (which I quickly realized does nothing.)

It should work, I don't see anything that is overriding it... unless I need parenthesis-

Hold on.

No, okay, didn't do anything.

[pearl swallow]

I’ll keep looking around in a bit, I gotta eat.

[slim adder]

How do I get all objects which lay in the game on top of the object?

I am trying to use Physics.Boxcast but it doesn't work

Is boxcast the right thing to use in Unity3d?

Or how should I do it?

[rustic rain]

This code is not working

i am using the new input system

and clicking on the gun doesnt have any effect

[leaden ice]

do you have an event system in the scene?

Any errors in console?

[rustic rain]

there is one, but it doesnt seem to be responding to other unity events either

is there a way to regenerate the eventsystem?

[buoyant crane]

Use boxcastAll to get an array of colliders https://docs.unity3d.com/ScriptReference/Physics.BoxCastAll.html

[leaden ice]

does your canvas have a Graphic Raycaster?
And lastly - do you have any other canvases in the scene?

[slim adder]

Okay great thank you!

[thick socket]

 public event Action<Items> addItem;
    public void AddItem(ItemReqs itemReq)
    {
        //addItem?.Invoke();
        Items item = new(itemReq);
        addItem?.Invoke(item);
        List<Items> tmpList = FindList(item);
        tmpList.Add(item);
    }
    public void AddItem(Items item)
    {
        addItem?.Invoke(item);
        List<Items> tmpList = FindList(item);
        tmpList.Add(item);
    }

first try using events...thought I had this setup right from the example Im following so not sure what is wrong

[leaden ice]

you need an object reference for the PlayerInventory instance you want

you can't just use the class name

[thick socket]

awesome thanks!

[rustic rain]

i have like 6 other canvases in the scene, and yes it does have a graphic raycaster. these are are all canavases

[leaden ice]

I would also recommend renaming your event to something like OnItemAdded which is more descriptive of what the event is.

[thick socket]

gotcha thanks...thought you were able to do it without needing reference to PlayerInventory?

[leaden ice]

the way you have it now seems confusing because it seems like it is actually adding the item rather than a reaction to adding the item

[leaden ice]

You always need object references to access non-static members of a class

[thick socket]

(following some tutorial that had things with collectable class that other subscribed to)

[leaden ice]

the event is a non-static member, so you need an object reference

If you use a static event you don't need an object reference.

of course that has other pitfalls 😉

[thick socket]

"me about to just make it static"

[rustic rain]

is it bad that i have different canvases for different things?

[leaden ice]

no

[rustic rain]

so what could be causing my issue then? im slightly confused

[leaden ice]

Your other canvases may have things that are blocking this one

For example a fullscreen image on one of the canvases that's in front of this one

[rustic rain]

theyre all inactive tthough i believe, i'll have a double check though

[leaden ice]

just for testing - disable you other canvases

and see if it works

[pearl swallow]

Back from eating, any advice for the code I have?

[rustic rain]

what does it mean if my cursor has a little lock on it?

[leaden ice]

not sure what you mean by that

[rustic rain]

still nothing, could it be to do with the fact im using the new input system? im using both for active input handling

[leaden ice]

no, you have the correct input module

so it's fine

[rustic rain]

to be clear, im currently trying to click on this gun image, which has the drag drop script, and it has thiis script

oh wait

[vagrant agate]

Is there a way to get the height of an canvas image in world units without me doing my own screen calculation.

[rustic rain]

i think the debug for comments was disabled 💀 @leaden ice

it was working this whole time

i didnt see that LMAO sorry

thanks for your help though

[pearl swallow]

Would anything in my physics do something with it?

[neon plank]

How can I request to not Burst compile some methods in a job?

[BurstCompile]
private struct MyJob : IJob
{
     // Not Burst this
     public void Execute()
     {
          ManagedCode();
          UnamangedCode();
     }

     // Not Burst this
     void ManagedCode() {}

     [BurstCompile]
     void UnamangedCode() {}
}

[lucid valley]

I think that should work

On IJob and IJobParallel you have to put [BurstCompile] on Execute as well for it to be burst compiled

[somber nacelle]

https://docs.unity3d.com/Packages/com.unity.burst@1.8/manual/compilation-burstdiscard.html

[lucid valley]

nope

nope

nope

do not fall for that trap

it doesnt work like that

[leaden ice]

Lol

[lucid valley]

[BurstDiscard] literally means the code wont be compiled when burst is on

[leaden ice]

Oof

Not sure you can get method level granularity with it

It's at the job level right?

[wintry crescent]

Hi, should I grab input always in Update, or is FixedUpdate fine? Assuming I'm using Input.GetAxis (no GetKeyDown etc.)

[somber nacelle]

damn the docs really do not make that clear

[lucid valley]

dw, i fell for it too. The paragraph in the example explains it properly

[leaden ice]

Always Update is best practice but if it's continuous input it will technically work ok in FixedUpdate

The idea is that Update is the exact cadence that input data updates so you will be reading it exactly when it may change. No more no less.

[neon plank]

It doesn't work. I already tried and got surprised to discover that it "deletes" the method

[leaden ice]

What's your goal? Why do you want to disable burst for the method

Are you trying to access managed objects or something?

[neon plank]

Half the job uses managed code, half the job doesn't, my goal was:

void Execute(int index, TransformAccess transform)
{
    Managed1(...);
    Unmanaged1(...);
    Managed2(...);
    Unamanaged2(...);
    Managed3(...);
}

And apply BurstCompile to the unmanaged ones.

[lament mural]

I'm using a character controller for my player. I noticed that when platforms collide with the player, they don't always push it. If the player is standing completely still, the platforms will pass right through it. Does anyone know how to fix this?

[neon plank]

Yes

[leaden ice]

you can't use managed objects in a job no matter what

[neon plank]

I can

[lucid valley]

you technically can through statics (not that doing that is recommended as it avoids the safety system)

[neon plank]

It works, but the Burst fail

[lucid valley]

you just can't pass them into the struct

[neon plank]

Exactly, or by pinning objects

In my code, since this is a global manager, I just used static to get the managed data

[lucid valley]

what you put above should work (as the execute isnt [BurstCompile])

whats the error?

[leaden ice]

I have no idea then

guess I was mistaken

[leaden ice]

maybe you need to separate this into two jobs one that uses managed objects and one that doesn't.

[neon plank]

No, the compiler tries to Burst the Execute, which fails:

Burst error BC1042: The managed class type `NavigationAgent[]` is not supported. Loading from a non-readonly static field `NavigationAgentManager.agents` is not supported

[neon plank]

It would be 5, and I was using that before... but I noticed that scheduling 5 jobs per frame was quite expensive... so I wanted to reduce it to 1

[lucid valley]

The job start at lines 286

[modern creek]

I can't brain this morning. I want this gel ball to bounce around at a constant speed, but ... it's not. Any ideas?

        private IEnumerator GelFloatCoroutine()
        {
            Vector2 endPos = GetNextGelLocation();
            float _duration = Mathf.Abs(((Vector2)transform.position - endPos).magnitude / 800f);
            _currentTween = transform.DOLocalMove(endPos, _duration).SetEase(Ease.Linear);
            yield return _currentTween.Play().WaitForCompletion();
            transform.localPosition = endPos;
            DoNextAnimation();
        }

GetNextGelLocation() gets a Vector2 along the edge of the screen

oh!

.position and not .localPosition

🤦‍♂️

[lucid valley]

huh sorry, i think i might be just misremembering it

I guess Execute is always burst compiled with that attribute

I guess the way to get around it is to have the logic in a separate class

[wintry crescent]

I am heartbroken to discover that those are worldPosition. Is there an easy way to make a rigidbody be constrained in localPosition?

[neon plank]

Why they made that??

[neon plank]

Yep, sadly

[leaden ice]

not built in, no

[wintry crescent]

:c thanks

[lucid valley]

thats the work around

[neon plank]

Ok, thanks

BTW, it's me or if I apply BurstCompile to a method, it will "propagate" that attribute to any method that it calls (i.e: it will also Burst compile them)?

[lucid valley]

yup, thats how it works

[neon plank]

Interesting

[lucid valley]

so if you have any downstream managed stuff then you can't use burst

[neon plank]

Ok

[abstract cypress]

The line 108 throws a StackOverflowException. _replayBuffer is a Queue and this method is called up to 60 times a second. How do I avoid the StackOverflowException and why does it happen?

[neon plank]

Is there any reverse P/invoke or stuff that I can use to call managed code from Burst?

Just wondering

[lucid valley]

gotta admit i've never tried

[leaden ice]

A StackOverflowException usually indicates unbounded recursion. A good first step to investiaget would be to look at the full reported stack trace in the error message

[thick socket]

public void SetPlayerStats()
    {
        int hp = 500;
        int atk = 100;

            }
        }
        GameManager.instance.player.SetStats(hp, atk);
    }```
Having this called in constructor of class throws errors...however having it set in another class like this doesnt...any ideas why?

 playerInventory = new();
        ExampleInvAdd();
        playerInventory.SetPlayerStats();

[silk horizon]

Hello

[lucid valley]

well there's obviously some race condition then

which part in this is null GameManager.instance.player?

[thick socket]

nope

[leaden ice]

is this object a MonoBehaviour? You cannot create MonoBehaviours with new().

[lucid valley]

something hasnt been set up in time

[leaden ice]

Also share the error(s)

[thick socket]

neither is GameManager.instance.player.stats

[thick socket]

¯_(ツ)_/¯

playerstats are setup in awake

[lucid valley]

well is the GameManager instance also set in awake?

[thick socket]

yes

[lucid valley]

...

can you see the issue

[thick socket]

player is set publicly

[leaden ice]

So then which awake is running first?

[thick socket]

aka drag in

[thick socket]

inventory isn't created until start

[leaden ice]

Awake is before Start

[thick socket]

public class GameManager : MonoBehaviour
{
    public static GameManager instance;
    public void Awake()
    {
        instance = this;
    }
    public void Start()

        //could try 60 also for ex)
        Application.targetFrameRate = Screen.currentResolution.refreshRate;
        Scene a = new Scene();
        LoadSceneMode b = new LoadSceneMode();

        SceneManager.sceneLoaded += LoadState;
        SceneManager.sceneLoaded += FindPlayer;
        SceneManager.sceneLoaded += FindEnemies;
        LoadState(a, b);
        FindPlayer(a, b);
        FindEnemies(a, b);
        playerInventory = new();
        ExampleInvAdd();
        playerInventory.SetPlayerStats();
    }```

[leaden ice]

Where does BootStrapper:Execute() run

[thick socket]

public class Player : Fighter
{
    float movement;
    bool jump;
    bool down;
    protected TextMeshProUGUI hpText;
    [SerializeField] Joystick joystick;

    [SerializeField] int atk = 3;
    [SerializeField] float atkspd = 1f;
    [SerializeField] int multishot = 1;
    [SerializeField] Transform head;

    bool isMobile = false;
    protected override void Awake()
    {
        base.Awake();
        myJumps.maxJumps = 2;
        stats.attackDmg = atk;
        stats.attackSpeed = atkspd;
        stats.multiShot = multishot;
    }```

[leaden ice]

^?

[thick socket]

using UnityEngine;

public static class BootStrapper
{
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
    public static void Execute() => Object.DontDestroyOnLoad(Object.Instantiate(Resources.Load("Systems")));
}

[leaden ice]

Ok that's going to be before any of your Awakes

[thick socket]

not quite sure how it would cause the issue still

[leaden ice]

What script(s) are on the Systems object

PlayerInventory?

Show this line? PlayerInventory.SetPlayerStats () (at Assets/Scripts/Inventory/PlayerInventory.cs:212)

[thick socket]

kinda...playerinventory is created inside the gamemanager

oooh

I have it created in another spot also

[thick socket]

GameManager.instance.player.SetStats(hp, atk);

what Im finding says GameManager is null

[leaden ice]

yeah looks like PlayerInventory.Awake is running before GameManager.Awake

[thick socket]

how could that happen if the only instance its created is inside GameManager?

[leaden ice]

I don't see any instance being created in GameManager. Are you talking about this?
playerInventory = new();

that's a giant red flag anyway

you cannot create MonoBehaviours with new

[thick socket]

it isn't a monobehavior

just a regular ol class

public class PlayerInventory
{
    public List<Items> ArmorList { get; private set; }
    public List<Items> WeaponList { get; private set; }
    public List<Items> JewelryList { get; private set; }
    //Helmet, Armor, Weapon, Jewelry
    public Dictionary<ItemType, Items> EquippedList { get; private set; }
    int gold;
    int gems;
    int xp;
    public PlayerInventory()
    {
        ArmorList = new();
        WeaponList = new();
        JewelryList = new();
        EquippedList = new()
        {
            { ItemType.Armor, null },
            { ItemType.Weapon, null },
            { ItemType.Jewelry, null },
            { ItemType.Undefined, null }
        };
        SetPlayerStats();
    }

[leaden ice]

gotcha. Looks like there's one being created in GameHandler too?

[thick socket]

commented it all out

using UnityEngine;
using System.IO;
using Assets.HeroEditor.Common.Scripts.CharacterScripts;
using Newtonsoft.Json;

public class GameHandler : MonoBehaviour
{
    string path;
    string json;
    public Character character;

    void Start()
    {
        //path = UnityEngine.Application.persistentDataPath + "/Inventory.json";
        //SaveInv();
        //LoadInv();
    }
    public void SaveInv()
    {
        PlayerInventory test = new();
        //json = JsonUtility.ToJson(test);
        json = JsonConvert.SerializeObject(test);
        Debug.Log(json);
        //Debug.Log(test.bag.Count);
        //Debug.Log(test.equipped.Count);
        File.WriteAllText(path, json);
    }
    public void LoadInv()
    {
        json = File.ReadAllText(path);
        //Debug.Log(json);
        PlayerInventory test = JsonUtility.FromJson<PlayerInventory>(json);
        test.EquipOnLoad();
    }
}

so it should only be created/happening inside gamemanager

(and shopEquipment which is in the scene)

[leaden ice]

where do you assign GameManager.player?

[thick socket]

public void SetPlayerStats()
    {
        int hp = 500;
        int atk = 100;
        foreach (var item in EquippedList.Values)
        {
            if(item !=null)
            {
                hp += item.hp;
                atk += item.atk;
            }
        }
        if (GameManager.instance == null)
            Debug.Log("GameManager is null");
        if (GameManager.instance.player == null)
            Debug.Log("player is null");
        if (GameManager.instance.player.stats == null)
            Debug.Log("stats is null");
        GameManager.instance.player.SetStats(hp, atk);
    }

it throws error saying the GameManager.instance ==null

[leaden ice]

ok good

[thick socket]

public class GameManager : MonoBehaviour
{
    public static GameManager instance;
    public void Awake()
    {
        instance = this;
    }
    public void Start()
    {
        //could try 60 also for ex)
        Application.targetFrameRate = Screen.currentResolution.refreshRate;
        Scene a = new Scene();
        LoadSceneMode b = new LoadSceneMode();

        SceneManager.sceneLoaded += LoadState;
        SceneManager.sceneLoaded += FindPlayer;
        SceneManager.sceneLoaded += FindEnemies;
        LoadState(a, b);
        FindPlayer(a, b);
        FindEnemies(a, b);
        playerInventory = new();
        ExampleInvAdd();
        playerInventory.SetPlayerStats();
    }

if I have it called SetPlayerStats() here it works...if I have the SetPlayerStats() inside constructor it breaks

¯_(ツ)_/¯

disabled ExampleInvAdd() and it still works...thus nothing inside that should be helping "fix" it

[leaden ice]

the thing is

look at this stack trace

GameManager.Start is not involved

Did PlayerInventory used to be a MonoBehaviour at some point in the past or something?

Somehow Resources.Load is directly calling the constructor 🤔

[thick socket]

not sure, it may have been at some point

GameManager has a public PlayerInventory playerInventory;

[leaden ice]

I wonder if your prefab doesn't have an orphan copy of the script on it still or something

[leaden ice]

oh right

this will do it

if its serialized

[thick socket]

but I don't have a =new() on it?

[leaden ice]

can you try making that [NonSerialized] for a minute

[NonSerialized] public PlayerInventory playerInventory;```

see if that changes anything

[thick socket]

that indeed does fix it thanks!

didn't realize if I just had it public it would auto-create a new()

[leaden ice]

Unity's serialization creates "empty" objects for all serialized fields

[thick socket]

good to know that [NonSerialized] is a thing to thanks!

[wintry crescent]

Hi, when I set rigidbody.centerOfMass=Vector3.zero, all child gameobjects with rigidbodies stop moving when the parent object moves - can this be remedied somehow? I need the centerOfMass to be zero, because otherwise when I rotate the parent object, the child objects are involved in calculating the center of rotation, which is not something I want

[leaden ice]

Are the child Rigidbodies dynamic?

Why do you have child rigidbodies?

Typically you have one Rigidbody parent and then just colliders as the children

[wintry crescent]

I have a big object, and small objects moving around on its surface
big object moves, small objects also move, but I don't want the big object to leave them behind

[leaden ice]

I would use two physics scenes for this

assuming you want the small objects on the surface to treat the big object as their entire world

[wintry crescent]

not exactly - the small objects need to interact with objects outside of the big object, random completely unrelated ones

[leaden ice]

Sounds pretty complex 😵‍💫 that could be done with proxy objects in the "internal" physics scene though

[wintry crescent]

your solution sounds complex 😵‍💫
but well, alright, I'll check out the physics scenes, never heard about them

[leaden ice]

Your game sounds complex 😜

I think you're going to end up with complexity either way here

[distant owl]

Hello, was wondering if anyone knew how to stop colliders from going through walls? Maybe cutting them off if that's even possible or somehow making sure if a player is directly in front of the collider but behind the wall anyone know any good tutorials for this or know how I would go about approaching this??

[wintry crescent]

you could use raycasts?

or boxcasts

[simple egret]

(non-trigger) colliders won't go through walls as long as you move the object in a physics-friendly way

ie. using a Rigidbody

[leaden ice]

Use a raycast as a secondary check when you detect a trigger to make sure it's in line of sight too

I assume this is for some kind of cone of vision kind of thing?

[distant owl]

actually yeah a raycast is something i didnt think about that

[distant owl]

and yes this is for a cone of vision

[distant owl]

oh okay however i need it to not collide with other objects

[simple egret]

So they'll go through walls

[somber nacelle]

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

[simple egret]

Can't have both at the same time

[distant owl]

oh yeah layering that also sounds like it

[molten sandal]

Question

RigidBody.velocity is in world space?

[somber nacelle]

yes

[molten sandal]

How to get the forward vector of object in local space?

[tidal shadow]

transform.forward

[leaden ice]

In local space?

Forward is always Vector3.forward in local space

in world space it's transform.forward

[molten sandal]

and in local space?

[leaden ice]

^

that's pretty much the definition of forward

[molten sandal]

what about?

[somber nacelle]

Vector3.forward

[leaden ice]

this will always give you Vector3.forward back

aka (0, 0, 1)

ummm how to fix this?
I'm using a rb.velocity to change player's positon

• This script to move on slopes

[static dew]

Anyone know how to return if a section of a texture is masked or not? I'm using a raycast & renderer.material.GetTexture("_MaskTexture"), but I'm not sure how to differentiate if the raycast is hitting the masked area or not.

[leaden ice]

what kind of mask are we talking about?>

[static dew]

It's a texture 2D asset input into my material shader, it adapts based on gameplay to create "painted" floors similar to splatoon.

[leaden ice]

So it's just one of the textures in your material? You'd have to read the texture at the UV where your ray hit and check what color the mask texture is at that point

[leaden ice]

See the code example here it's kind of close to what you want
https://docs.unity3d.com/ScriptReference/RaycastHit-textureCoord.html

This one writes to the texture, you just want to read.

In fact if you're doing a Splatoon thing you should be somewhat familiar with these techniques already

[fluid lily]

What would you call stats more generically? Like math wise even. Like I am thinking something like compoundable or something. You have your base value, and then modifier values on that(like adding specific value, multiplying by specific values).

[latent latch]

stats

[fluid lily]

I find it is a pattern I use other places more generically, but I can't think of something to call it more generically then stats.

[warm wren]

Statistics

[latent latch]

EntityStatistics

[leaden ice]

AugmentableValue
ModifiableValue
ModifiableStat

[fluid lily]

I always think of Statistics as more finding logic/patterns in math, not the modification of numbers/values.

AugmentableValue like that one

[fluid lily]

Someone understood the assignment 😂

[leaden ice]

ModifiableValue is what I use in my current project for a thing that has:

• base value
• additive modifiers
• multiplicative modifiers
• replacement modifiers

[static dew]

Much appreciated, this is a great reference for getting the UV position! For next steps I'll try to focus this specifically to the mask, and see what values I can get back with GetPixel

[latent latch]

I just have a class called BaseStat

[fluid lily]

I guess stats comes from dice times, where the outcome of actions is based on the likelyhood and combined values. Where in games it has more a meaning of just combined values.

Example: Your character has a statistically low chance of making that move work.

your stat, as it were, is too low

[latent latch]

DnD was always presented as ability scores, but lately people refer them as character stats

[fluid lily]

https://en.wikipedia.org/wiki/Statistic_(role-playing_games)

"There is no standard nomenclature for statistics; for example, both GURPS and the Storytelling System refer to their statistics as "traits", even though they are treated as attributes and skills."

I guess over all it is like the meaning for numbers in relation to an rpg, which does align with what I think of for statistics, but specifically what games call a stat would be attributes with modifiers mathmatically speaking.

"Bonus or base value"

Modifier makes more sense then Bonus, as I wouldn't consider a negative increase a bonus logically.

[thin frigate]

I'm trying to make a particle system (2d) that will generate particles from a point (bottom center) and have them fill the attached sprite. How should I go about doing this? Shape (Sprite) or ParticleForceFields seem like they could somehow be involved in this, but I don't know how

[neon plank]

Question, when using the NavMeshSurface, is possible possible to choose some layers to carve the nav mesh but not add? I.e: I want obstacles and walls to carve the nav mesh, but I don't want to have a nav mesh on top of a large box.

[swift falcon]

Using RealtimeCSG, I created a massive bounding box about 1 cubic kilometer in volume, with walls about 1m thick, to act as an "out of bounds" area, which would cause projectiles to disappear and players to die/teleport upon touching it, so that nothing deviates infinitely from the level.

However it seems many of my projectiles phase through this box, meaning they won't disappear at all. Is there anything I can do to improve this collision system?

[leaden ice]

1. Make the walls thicker
2. reduce your fixed timestep
3. reduce your projectile speed
4. increase your projectile collider size
5. Use a simple BoxCollider instead and use OnTriggerExit to destroy the bullets

[swift falcon]

1. Make the walls thicker
   Alright, good... that was an idea I had... 🤔

2. reduce your fixed timestep
   What do you mean?

3. reduce your projectile speed
   No can do.

4. increase your projectile collider size
   I may consider this. 🤔

5. Use a simple BoxCollider instead and use OnTriggerExit to destroy the bullets
   A BoxCollider for what, exactly? The projectiles?

Also, I've been using OnTriggerEnter, so I'll try that. 🤔

[leaden ice]

5. A BoxCollider for the 1KM box

[swift falcon]

It will accommodate for the massive void in the middle, right?

[leaden ice]

there is no void

the idea with a box collider is they will always be overlapping until they are NOT

[swift falcon]

There is in my box.

[leaden ice]

at which point OnTriggerExit will be called

Then you know they are out of bounds

[swift falcon]

...

🤔

Huh.

So what you mean is have 'em always detect being within a big box, and when they're not in that box, they get despawned. 🤔

[leaden ice]

As for fixed timestep I mean this:

reducing it will mean physics simulation runs more frequently at smaller intervals of time

[leaden ice]

yes

[swift falcon]

Interesting... 🤔

Is there a way I can check for layers akin to CompareTag?

[leaden ice]

in what context

[swift falcon]

Because it seems some of the generated meshes do adopt the necessary layer, but not the necessary tag.

Which means CompareTag may not be useful. 🤔

[leaden ice]

I'm not sure I follow this conversation anymore

[swift falcon]

🤔

[leaden ice]

If you're trying to limit the OnTriggerExit to certain layers, you should use the layer based collision matrix in physics settings

[swift falcon]

Ok, so what I attempted to do with OnTrigger[Enter/Exit] was to see if it was in contact (or not) with a GameObject with the "Out Of Bounds" tag.

[polar marten]

you're overthinking this. also, this is buggy

[leaden ice]

you can do this still - or use layer based collisions to prevent other interactions

[polar marten]

if you need a bounding box, create a game object with 6 box colliders

do not try to use a mesh with a void in the middle as a physics mesh

it is physically invalid

does that make sense @swift falcon ?

you cannot use a mesh generated this way with realtimecsg (which i am familiar with) for the purpose you want

period full stop

[swift falcon]

So, bounding box ought to be a simple set of box colliders.

[polar marten]

that's correct

[swift falcon]

Ok.

[polar marten]

you can emit particles from a texture

[mystic ferry]

I love you guys

[polar marten]

use a pyramidal shape

[neon plank]

What you mean?

[thin frigate]

I don't want to create the particles in the shape of the texture, I want the particles to move so they fill the texture.

[polar marten]

it sounds like you are seeing this:

https://docs.unity3d.com/uploads/Main/NavMeshMinRegion.svg

[thin frigate]

There may be a way to use emission from texture to work, but it creates a weird effect I'm not a fan of right now

[polar marten]

well that's tricky now isn't it

maybe ask vfx and particles

[neon plank]

We don't want to alter the shape of our obstacles and stuff

[polar marten]

tough cookie. try to be creative with the differences between what is marked navigation static and what is not

you can use different geometry for navigation than for rendering

you can also specify navigation area as non-navigable i believe

lots of easy fixes

read the docs

https://docs.unity3d.com/Manual/nav-BuildingNavMesh.html

[neon plank]

But then how can I specify an entire layer to be of an specific area?

[polar marten]

the general technique to get particles to move in a certain designed path is called... something about vector flow that i am still looking up

don't remember exactly

[polar marten]

you can't. you can mark the objects as the docs show you

use the docs

[neon plank]

That doc is about the old workflow.
I'm using the component based workflow...
I know I could add NavMeshModifier to each obstacle. But I wanted to know if there was a simple solution layer-wide.

[polar marten]

i think you add navmeshmodifier to each obstacle

[neon plank]

Ok

[polar marten]

[faint brook]

any ideas on how to increase randomness i have the following ```c
agent.transform.localPosition = new Vector3(Random.Range(-2f, 2f), 4f, Random.Range(-2f, 2f));
Random.InitState((int)System.DateTime.Now.Ticks * 123);
block.transform.localPosition = new Vector3(Random.Range(-2f, 2f), 4f, Random.Range(-2f, 2f));
Random.InitState((int)System.DateTime.Now.Ticks * 321);
goal.transform.localPosition = new Vector3(Random.Range(-2f, 2f), 3, Random.Range(-2f, 2f));

but this seams to keep them relativly together

also only spawns in the top half of the parent

[leaden ice]

Why are you setting the state of Random manually?

There's no need for that

Unless you're doing some kind of seeded deterministic thing

[faint brook]

no I am not I just read that that can help

[leaden ice]

Also casting Ticks to an int is going to end up truncating probably

So you're likely setting the seed identically in both those calls

Hence non randomness

They're spawning at the top because you're using constant y positions, no?

[faint brook]

by top half I mean from a birds eye sorry for the confusion

as you can see the objects spawn close to each other especially the blue and the green(in this case)

[leaden ice]

well you're only spawning within this -2, 2 range

that's not very far

And depending on the scale of the parent object it may be even smaller

[faint brook]

I was under the impression that -2f , 2f was the range of the parent?

[leaden ice]

huh?

wdym by that

[faint brook]

when I set it to -10f 10f (the size of the parent) it always spawns out side

[leaden ice]

I don't know what to say

it's just a random position between -2 and 2

it has nothing inherently to do with the size of the parent

(other than being affected by its scale, since it's local position)

[faint brook]

oh 🤦‍♂️

[leaden ice]

if the parent is 10x10 then you'd do -5 to 5

[uncut tundra]

[faint brook]

I set it to -5,5 and the objects spawn outside pretty often

[leaden ice]

because you're trying to read input in FIxedUpdate. You should only read input in Update

[uncut tundra]

Ok, thanks

[mystic ferry]

man I feel like I could spend a lifetime learning this engine and still barely understand it

I've been studying it like CRAZY for over 3 years and I still see shit I've NEVER seen before to this day

[leaden ice]

any sufficiently complex piece of software is like this

[mystic ferry]

I guess, but you'd figure it'd slow down eventually

I haven't even touched any of the DOTS stuff yet. And that's probably a huge rabbit hole

[swift falcon]

Does scaling a game object also scale any colliders attach to it and its children?

[leaden ice]

yes

[swift falcon]

Interesting.

Cool. 😄

[leaden ice]

Note there are some caveats to that when it comes to colliders. SphereCollider is always a sphere, even if you try to "skew" it with a weird scale. Similar restriction on CapsuleCollider

[swift falcon]

Does it expand to the largest of the coordinates?

[leaden ice]

something like that. I don't remember exactly

[swift falcon]

k

[leaden ice]

maybe the smallest, maybe the largest 😉

[swift falcon]

lol

[thin frigate]

Realistically, how much of an impact of performance do public references have? I've always been taught that avoiding unnecessary public references is good practice, but if my game is having performance issues how likely is it that they're the cause?

[leaden ice]

approximately 0%

Use the profiler to diagnose your performance issues

[thin frigate]

What's that?

[leaden ice]

the tool designed to diagnose performance issues

[thin frigate]

Alright better question, where's that

[mystic ferry]

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

google is a thing you will need to use a lot if you have any hope of creating a game

[cosmic rain]

Avoiding public references is good practice, but not for performance reasons.

[thin frigate]

What reasons, then?

[cosmic rain]

Good code.

[mystic ferry]

classes that interact with a bunch of other classes is a mess to code, debug, everything

[cosmic rain]

Readability, extendability, debuggability.

[mystic ferry]

but you'll write trash code in the beginning no matter what which is to be expected

you have to understand what's wrong with bad code by writing some before you can understand how to avoid/fix it

people can tell you it's bad all they want but until you understand it from personal experience I doubt it'll really do anything

just my two cents

[swift falcon]

Hmm, looking for some help if anyone can provide a bit of feedback! Context: moving rigidbodies while simultaneously applying velocity (moving platforms, but learning what's wrong will help me with a lot I'm sure)

Currently my character controller is a rigidbody2d controller that adds force to the player in fixedupdate depending on inputs.
The platform script is detecting rigidbodies on collision and then using transform.translate to move them (in lateupdate). It uses the platform's stored last position and current position to figure out what to do.

The problem currently is the platform causes visual jitter to everything riding on top of it, and there's definitely something wrong.
I mostly understand what's going on, but the specific details of the issue feel like I'm not quite grasping ahold of enough info to figure out what I need to change. If I had to take an educated guess I'd probably think it was related to a number of things including when I'm calculating/moving the RB, as well as potentially needing to lerp the values or something... A bit clueless though.

If anyone has resources to guides on the topic that are better than the random youtube info I keep stumbling into, and can point me in the right direction (or can tell me straight up what the problem is) I'd be grateful

[swift falcon]

this is a different approach I tried, using parenting the object (player in this case) to the platform on collision

it works a lot better, and seems to be fine, save for the issue of some persistent jitter I can't get rid of

[potent sleet]

why are u even doing this

dont use translations for rigidbodies

[swift falcon]

see I'd heard not to before, and then every tutorial or post on a forum goes "translate it lol"

I feel insane

[potent sleet]

if you want your props to move with the platform you could potentially use joints or make it kinematic with parenting

[mystic ferry]

translations completely avoid the physics engine so no collisions, shit can warp through walls etc

[swift falcon]

right,

so what would a best practice be for moving platforms carrying rigidbodies/the player

exerting additional forces?

[potent sleet]

I told you a few options

[swift falcon]

I'll need to look into joints. Making it kinematic doesn't sound like it will work for me though, since I'd want it to continue to function as a dynamic object

I'm not really sure though. I'm reaching a point where I wonder "Should I just code everything as kinematic?"

[potent sleet]

kinematic can be toggled on and off

such as OnCollision with player or something

[swift falcon]

I'm trying to imagine what I'd need to change in the controller to accommodate a shift to kinematic

there

may not be issues, now that I think about it

thanks, it's something to think about for the moment

[potent sleet]

also are those meshes ? or are you just using 2D colliders

[swift falcon]

2d colliders, I'm rendering 3d meshes but the game is using 2d for everything

this way I can do funny things with lighting and animation

[potent sleet]

did you try only moving platform with Add.Force ?

[swift falcon]

like, a platform with it's own rigidbody and force to move location?

no I have not

[potent sleet]

ohh so the platform isn't rigidbody ?

[swift falcon]

correct

[potent sleet]

thats what I meant when i said kinematic

but that would require diff movement than addforce

[swift falcon]

I'm just generally confused now. So, did you mean change the player to kinematic to match the platform? Or did you originally mean make the platform kinematic

if I make the player kinematic at any point I've got to use some different method to move them, since force can't be applied to kinematic objects, correct?

[potent sleet]

is the player also a rigidbody ?

[swift falcon]

the player is an RB2D

dynamic objects for physics based interactions I wanted to be rigidbodies

[potent sleet]

oh ok , try only having platform move with addforce

[swift falcon]

alright

[tawny mountain]

Not sure where to post this
But
What is the easiest way to set up player data recovery when using firebase firestore?

[leaden ice]

"player data recovery" is a vague and probably complicated subject

you'd have to explain exactly what that means in the context of your game

[mystic ferry]

does anyone know what retail disks and gold master disks are? this is the steamworks sdk docs

it just kinda uses the terms like everyone knows what they mean, and I can't find anything about it anywhere

[potent sleet]

disks ? what is this 2007

[mystic ferry]

I'm pretty confident they don't mean physical disks? but I don't know

not sure what else they would mean

nevermind. Maybe that's exactly what that means

"A final version of software ready for release to manufacturing"

[potent sleet]

some form of protection?

i think has to do with DRM stuff

[mystic ferry]

https://partner.steamgames.com/doc/sdk/goldmaster

this is the docs if you're curious

maybe I'm just stupid lol. Can't really figure it out

[potent sleet]

I think it's literally what I said lol

has to do with putting your game on disk and auto install from steam or something

i think

[thin frigate]

Is checking if( GameObject.GetComponent<T>() != null ) significantly more performance intensive than implementing a Tag system for type T and using that?

[potent sleet]

so like people with shite internet can still install your game without steam download

[mystic ferry]

interesting

[potent sleet]

just a disk?

[mystic ferry]

I didn't even know that was a thing

[potent sleet]

The Steamworks SDK includes a customizable installer that you can include on your gold master. The installer is designed to help users install Steam and begin loading your game as quickly as possible. The installer has also been designed to ensure compatibility with the installation portion of the Games for Windows certification.

like if you create special edition probably with art and shit

[mystic ferry]

steamworks docs try not to be impenetrable challenge difficulty impossible

thanks king @potent sleet

[cosmic rain]

Not sure what you mean by a tag system for type T

But get component is not that heavy.

[thin frigate]

I just mean using tags instead of GetComponent

[potent sleet]

it's always better to use types than strings imo

[potent sleet]

strings aren't type safe and very brittle @thin frigate

[swift falcon]

yeah it literally just works this way and idk why anyone ever was telling me to do it differently

[mystic ferry]

if you're caching component references it shouldn't even matter

[potent sleet]

which way?

[swift falcon]

kinematic platform moved with force

[potent sleet]

noice

[cosmic rain]

Get component might be slightly slower, as it probably needs to loop the list of components on the GO.

But the difference is probably negligible

[thin frigate]

Alright

I'm trying to optimize my code to deal with having even a handful of projectiles in the scene at once, and it's being difficult.

[mystic ferry]

I always say bro optimize geometry and draw calls

ain't no way the fraction of a millisecond you save avoiding the lightning fast GetComponent calls are going to put a noticeable dent in anything

plus use the profiler anyway

[thin frigate]

This is a 2d Asteroids clone, I'm not sure how applicable that is here

[mystic ferry]

then performance is a nonissue

[thin frigate]

also I don't want to be assed to wait 20 minutes for a build

It IS an issue, though, that's the issue.

[mystic ferry]

what does the profiler say

[thin frigate]

Like I said, I don't want to wait for a build

I probably should, but

[mystic ferry]

what does that even mean

the profiler doesn't need a build

[thin frigate]

It doesn't?

[polar marten]

this call is unlikely to appear in your profiler

[mystic ferry]

I don't even know if you CAN use the profiler in a build, it's in the engine

[polar marten]

have you looked at corgi engine 2.5d?

[swift falcon]

I have not

I'll give that a look

[mystic ferry]

Window -> Analysis -> Profiler

[thin frigate]

The implementation is inside of my collision checks, so this is being called for every single object in the scope.

[polar marten]

what does the profiler say

[thin frigate]

This I guess

[mystic ferry]

spend some time learning how to read the profiler

it's going to be much more useful figuring out where you're writing inefficient code that way then just guessing at optimizations that might not even do anything

it'll even show you how much memory different things are using. It's extremely useful

[potent sleet]

you probably want hierarchy view not timeline

look up tutorials

[thin frigate]

already on it

[swift falcon]

Looks neat, but most things I can implement seem easy enough to tackle myself. I've already solved slope movement, etc. My plans are pretty extensive, so it's probably best I handle it all myself.

[thin frigate]

Alright apparently around 85% of the performance was being taken up by drawing gizmos. not very cool.

[mystic ferry]

there you go

[tawny mountain]

I currently have players anonymously authenticating with firebase , then they can choose to link with facebook.. I save the players data on firestore naming the doc the players uid.. now if my player clears local data and gets back in to the game a new anonymous auth is created and when logging in to Facebook again it tries to re-link to the new account , I'm unable recall the players originally assigned uid.. I'm currently working on a solution by trying to save email and uid on realtime Database

[swift falcon]

Hrmm, if addforce works on kinematic objects.. addtorque should as well, right? in order to rotate it.
I just wanted to test rotating a kinematic platform in place.

given it's a 2d rigidbody, this should be all it takes, I believe

[dusk apex]

Forces shouldn't work on kinematic objects. Guessing you meant non-kinematic objects.

[swift falcon]

Oh sorry, I see

I'm confusing velocity and force

[leaden ice]

Yes you need to associate the email or Facebook account with your user account that's all

[swift falcon]

what's the term for the velocity equivalent for rotation? is there one?

[leaden ice]

Velocity doesn't work on kinematic objects either, unless you're in 2D

[swift falcon]

I am in 2d

[tawny mountain]

I got it somewhat working but it seemes I have messed up something.. One minute I'll show what I've got vs what i want and show the script

[leaden ice]

[leaden ice]

It's pausing because you have an error and you have error pause on. Fix your error

[sterile zealot]

Thanks for that. Now I know

[pure flint]

I made a List/Array and I wanted to reference all child gameObject in parent into the List/Array automatically by script I couldnt figure out how. Anyone got ideas?

without find tag if possible

[leaden ice]

What's a List/Array? It's either one or the other

[pure flint]

Well its more to List

[sterile zealot]

@dusk apex Would my code update the text, if it wasn't assigned under Inspector?

[pure flint]

like List<GameObject> those stuff

[tawny mountain]

An array would be like
GameObject[]

[sterile zealot]

I've seen where this might be related to not have an instance, but it's a single player game and only one Money UI text field. Do I really need to do a search/find on the name of my TMP_Text?

[pure flint]

uh yea I know cause they're almost the same thing except List is more flexible

[pure flint]

so Im trying to figure this out

with list

[tawny mountain]

You mean to make a variable reference

Make it public and drag and drop it in the inspector

[sterile zealot]

Yes, It's like the game's score. My code works but is giving me NullReferenceException: Object reference not set to an instance of an object
GameManager.Start ()

[dusk apex]

Show the inspector.

[tawny mountain]

Yeah the reference isn't comeplete

[dusk apex]

If it's not assigned, accessing the text property of the tmp component will throw an NRE.

[leaden ice]

You have a copy of the script in the scene with the reference left unassigned.

[tawny mountain]

Make the variable public and drop the game object in to the slot

[sterile zealot]

This is what is throwing me off because I have it assigned here underlined in red

[leaden ice]

#archived-code-general message

[leaden ice]

Cool now show all the other copies in the scene

[sterile zealot]

Do you mean all the TMP_Text?

[leaden ice]

No

All of the GameManagers

[tawny mountain]

Is it a child object? Does the parent get disabled on start?

[celest pendant]

hello

[dusk apex]

Debug.Log($"{name} has this script", gameObject);

[celest pendant]

I am newbie, which projects do you suggest me to learn unity? I can use c# and unity well.

[leaden ice]

!learn

[tawny elk]

🧑‍🏫 Unity Learn can offer you over 750 hours of free live and on-demand learning content for all levels of experience! Make sure to check it out at https://learn.unity.com/

[sterile zealot]

My TMP_Text is a chid of Canvas->UI

[leaden ice]

Stop worrying about the text

[celest pendant]

@leaden ice I have completed unity learn 2d ruby game doc. It was awesome and I have learnt awesome things. Yet, I like to build something from scratch by my own self. What do you suggest me to build ?

[sterile zealot]

Canvas and Canvas->UI->MoneyText are the only two things in my scene that call to GameManager at the moment

[leaden ice]

Find all the GameManagers in the scene

Delete the extra copy you forgot about

[tawny mountain]

Make data recovery

[leaden ice]

Wdym "call to GameManager"?

[sterile zealot]

That has the Script GameManager in it

Under Inspector

[leaden ice]

Find all of them

You really should only have one

Fix any without a reference set

Or delete it if not needed

[sterile zealot]

Sorry PreatorBlue but I'm not sure what you mean by having multiples

[leaden ice]

You have that script attached to multiple objects in the scene

Find them and fix it

[dusk apex]

Did you try placing this log in your code?

In start preferably

[sterile zealot]

@dusk apex Yes. I got just this

MoneyText has this script
UnityEngine.Debug:Log (object,UnityEngine.Object)
GameManager:Start () (at Assets/Scripts/GameManager.cs:26)

[dusk apex]

Did it print once only?

[sterile zealot]

Correct

[leaden ice]

Are you sure it didn't print twice? Do you have Collapse enabled on your console window?

[sterile zealot]

I'm sure, I just doubled checked for you

[leaden ice]

Maybe you have the script on that one object twice

[sterile zealot]

Okay.. Take made me think of something. I did have it also listed under the parent Canvas object

I unticked it and error goes away

[leaden ice]

...

[dusk apex]

Try logging the value of the money text component cs Debug.Log($"{name}'s component for money text was : {(moneyText != null ? "Not Null" : "Null")}");

[sterile zealot]

I'm still getting use to Unity, so it one script per object?

[leaden ice]

It's as many as you want but it needs to make sense

Anyway the log wasn't printing because you put it after the code with the error

[dusk apex]

Ah, so there were two.

[leaden ice]

Yes

[sterile zealot]

Okay, so if I have more than two references to the same script in a scene I need to do the search/find?

[leaden ice]

He even said as much here

[leaden ice]

No

Irrelevant

The number doesn't matter

You have to assign your references that's all

[deep willow]

im looking into doing pathfinding on a grid, but i need to find the nearest enemy on the grid while moving around allied units. can i use pathfinding to find the nearest enemy then actually follow that path?

[sterile zealot]

Well my code hasn't change just the references

[rigid island]

A*

[leaden ice]

Of course, why not?

[deep willow]

i cant just find the nearest enemy in a range

[leaden ice]

Yes.

[rigid island]

why not?

[sterile zealot]

So what would be the Correct way if I had it with two references?

[leaden ice]

Use Breadth First Search to find the nearest enemy in range

[deep willow]

i need to find the nearest enemy that is the fastest to get to

[leaden ice]

IDK what you mean. You just have to assign all your inspector references

You didn't assign one of them

[sterile zealot]

Ah... that's making more sense now

[dusk apex]

Maybe you're mistaking the word references for instances

[sterile zealot]

Yeah that second one is showing up but nothing is assigned so it's showing NULL

Ugh.. so dumb when you know what's going on

[dusk apex]

If you've got two instances in the scene, each instance must have their fields properly set before using their fields else you'll get NREs

[sterile zealot]

I just updated this code to get it working tonight, so left out something PraetorBlue was right

[rigid island]

does A* not work ?

[leaden ice]

A* is for pathfinding

[sterile zealot]

Yep.. Thanks for that.. I thought I only had one until I went looking and saw what PraetorBlue was talking about.

[leaden ice]

To find the nearest enemy you would use Dijkstra's

[dusk apex]

When you drag something into the field, that field now references what's been dragged in via inspector.

[deep willow]

can i ask A* to find the nearest enemy taking into account allies? then move to that enemy?

[leaden ice]

Or just depth first search

A* is for navigation to a known destination

[dusk apex]

Sure

[deep willow]

yeah thats what i thought

[sterile zealot]

Now that I'm on this side of understanding the problem, it's a really basic and dumb mistake..

[deep willow]

i need to search for the destination then pathfind to it

[leaden ice]

Dijkstra's algorithm will give you both the nearest enemy and the shortest path to that enemy

[deep willow]

ah okay

Breadth First Search will find the fastest distance to any enemy?

[leaden ice]

Breadth first search is basically Dijkstra's with the assumption that all edges in the graph are equally weighted, which is likely the case for a basic grid.

[rigid island]

I see you took some inspiration from my code ? @long totem

[long totem]

I think I copy & past somewhere else months ago XD

Last time it worked fine

I just dont know how it stop working suddenly

[rigid island]

what "stopped working"

[long totem]

the capture screenshot button here

Normally It wont be grey right?

[rigid island]

it's always gray

[leaden ice]

That's not a button. Just a reference to the script asset

[long totem]

Oh

So, uh the problem is I couldnt capture the rendered screenshot

[rigid island]

in what sense ?

code errors or what

[long totem]

And I just noticed the classes are not green

[rigid island]

you might need to configure your VS then

[long totem]

those under public class

[rigid island]

we don't have much to go by here, show some code or anything relevant

so what happens when you run the code

It wont capture the the screenshot when I click "camerainfo"
