[leaden ice]

Or whatever the variable is tracking

[jaunty sundial]

And then just divide by 100 when i need the value

[leaden ice]

You can consider each one as 1/100th of a unit. Just convert as needed when multiplying or displaying it. But store it in a long or int

[jaunty sundial]

Huh ok

[ancient sable]

THAT EXISTS? I was looking for something like this and never found it. Lmao, thanks. Just wondering, if I want to determine all of the triangle index would I still need to iterate through all of the collision points, or is there some mass version of that function since clearly I missed stuff in the documentation. And on that note, I really gotta get better at reading docs

[lean sail]

ive never really looked into doing a ton of raycasts at once, so im not sure about that part. i know theres something related to jobs about that.
and yea i assume you would iterate through the contacts and do a Collider.Raycast for each one.

[ancient sable]

Ok cool, thanks for the info.

position problem; I did the advancement process by adding the spline position to the vehicle position. but as I said before, I am chasing this vehicle. when I get in front of the vehicle. it should continue on a path that is not closed to the left and right. it should turn in reverse if necessary. it is quite suitable for predetermined fixed movement routes, but not a route system, but a system such as a rail is required for escape. it should only move on the rail. the escapes will change completely according to the scenario of the game.

the character stops even though the joystick does not return to its normal position, and also the character follows the mouse position/pull (the further the pull, the faster the movement) how to fix?

Does anyone know how to fill in a script with my 3D Graphic modeling, so I can play my character?

I know how to do 2D, but not 3D.

I make 3D Graphics.

[west bough]

you were right. I bought it now after that video

this is exactly what I want

[soft shard]

Im not sure your question makes sense, are you asking how to write a script that spawns a 3D model instead of a 2D sprite? What code do you have already?

[bold wraith]

I want to add my player models to an asset with stock player action scripts.

[amber lake]

I want to use the Rotate method to rotate around an object locally can anyone help?

[final fox]

Hello, I'm trying to make an aiming system where instead of the player just point and clicking where they shoot, they hold down click and this 'aiming cone' appears, and it sweeps from left to right at moderate speed, the player has to let go of the mouse button to take the shot when the aiming cone is lined up with whatever they want to shoot.

But I'm not sure how to go about it, because if I want to rotate the aiming cone it will do as shown in the video. I want the top to stay at the player's feet and just the bottom bit moving from left to right if that makes sense?

[knotty sun]

it helps if you refer to the docs
https://docs.unity3d.com/ScriptReference/Transform.RotateAround.html

[amber lake]

i cant use rotateAround and Space.self together

need to figure out how to use rotate method to make it work

[knotty sun]

https://docs.unity3d.com/ScriptReference/Transform.TransformPoint.html

[amber lake]

so dont use rotate use transformpoint instead

[knotty sun]

yes, use transformPoint and RotateAround

[main tree]

can you help me with my problem

[knotty sun]

do not ping people into your conversation

[main tree]

sorry

[amber lake]

how would i do it using Rotate and including Space.Self into it

[knotty sun]

you wouldn't. Rotate is not a movement method which you need to have to rotate around an object

[bold wraith]

Does anyone know how to solve this? So the robotic character works at a player character? Most poses created.

[amber lake]

i need to find a way to use Space.Self but that doesn't work with RotateAround

[soft shard]

If the rigs are the same, you should be able to set your Animator controller to the one in your screenshot, if you have variants of it you can use overrides, for example public Animator anim; anim.controller = ...;

[bold wraith]

Know any links I can look at to do this manually?

Or can someone school me share screen?

[knotty sun]

Ah, just read your assignment. I think you are misunderstanding it.
use RotateAround to rotate the camera around the planet and use Rotate (Space Self) to keep the camera facing the planet

[lean sail]

the part of the assignment where they say "it may go wonky after awhile" might refer to the distance slowly changing over time using RotateAround. I think i read about someone else having this issue, though dont really use that function myself and havent had it happen to me.
If that is the issue, you can fix it by getting the direction (Vector3) from planet to camera, normalizing the vector, then scaling it to be the length you want. Basically always controlling how far it is from the planet

[amber lake]

MainCamera.transform.RotateAround(mars.transform.position, Vector3.right, -30f * Time.deltaTime); MainCamera.transform.Rotate(Vector3.right * -50f * Time.deltaTime, Space.Self);

[unborn elm]

Is it possible to have a Action in an interface? Basicly I have a skillTrigger interface and would like to inject the Ui elements with an subscription to the timer. Kind of stuck on the idea to use a delegate or action

[amber lake]

i think that should be right

[unborn elm]

Guess there should be other smart solutions around the problem

[lean sail]

that transform.Rotate looks very wrong, and doesnt seem to actually consider looking at the object. Im not sure if you're restricted from using certain functions for your assignment, but this would solve looking at the object https://docs.unity3d.com/ScriptReference/Transform.LookAt.html

[amber lake]

Camera.main.transform.LookAt(mars.transform); i have this outside the if statement

it works alri just when it gets to the top it does like a 180 and then back to viewing it

[lean sail]

maybe you want to just use a base class instead? interfaces cant have instance fields

[placid summit]

Hi been using IDragHandler with UGUI until I realised it does not care which mouse button is used to drag!! This is not helpful, anyone made it limited to left mouse button?

[lean sail]

you shouldnt need both lines, just LookAt or Rotate. But your Rotate is wrong right now, you'd have to do some math to get the eulers you want to rotate it by. Or do quaternion math to set its rotation

[amber lake]

we haven't done quaternion but i think its ok now

[unborn elm]

Yeah thats the route im going for right now, it is a bit messy though. So right now im getting the interface with getcomponent and doing a seperate getcomponent for the base class

and they are both effectivly returing the same object

Can you do something similar to "where T is" in a interface to somehow force it to implement the base class

[lean sail]

im not sure why you have an interface and a base class, you just need one from what youve described above

[unborn elm]

I guess thats true, I do have more than one interface now but could probobly merge those

with the base class that is

[lean sail]

that would apply to generics, you cant limit what implements an interface

[unborn elm]

yeah thats what I thought

[placid summit]

you can use an abstract class or base class - only use an interface if you really need to

[unborn elm]

But i guess a abstract base class or something like that then

[unborn elm]

I tend to rather do interfaces than inheritance, feel that its easier to structure

but in this case I think that will be the only way

[lean sail]

yes that was my initial suggestion. base classes if you need to have some fields associated with it, and then you can still do that subscription you mentioned in the base class

[placid summit]

not sure why but whatever works best!

[unborn elm]

Thanks for help, always great to get input

[soft shard]

You can also set the controller from the inspector if you dont need to update it by code: https://docs.unity3d.com/Manual/class-Animator.html - assuming you have a prefab with an Animator component attached

[placid summit]

why are tags strings and not something more optimised and how can I have an inspector for one?! They seem problematic

[somber nacelle]

if you're on Unity 6 there's the TagHandle struct you could use instead. you do still need to use a string to get the right handle

[placid summit]

not yet - found Cinemachine has inspector handling for selecting a tag at least!

[ebon linden]

can anyone give a script which manages photon multiplayer system for reference? preferably with audio chat if possible
i need urgently 😭

[spare dome]

We dont do handouts here

Besides multiplayer is extremely hard to implement I dont think any of us just has that lying around

[soft shard]

Multiplayer is not just a single script, its a large and involved part of online games, and there isnt usually a "plug and play" solution you can just drop into a project and have it work, every project is different - however Photon does have documentation and tutorials, which may be a good place to start

[serene veldt]

Hello everyone I am currently making a game as a programmer and I wish to learn to make tools to make it easier for other people (non-Programmers) to work on the project, but I dont know where to start. If anyone has leads that would help me a lot.

[hexed pecan]

Editor scripting is something to look at:
https://learn.unity.com/tutorial/editor-scripting

https://docs.unity3d.com/ScriptReference/Editor.html

[vagrant spade]

I'm using SetPixels on a texture I'm generating on start, I animate the colors (every frame...) and it works fine in the editor, but when I build to android, I just get the pink no texture color. It seems it's not allowing me to set the texture? I went through the documentation but couldn't really find anything. An ideas what might be wrong and what to explore?

[thick terrace]

can you share the code that does this?

[vagrant spade]

Sure thing

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    int tsize = 128;
    Texture2D tex;
    Color[] colors;
    float elapsed;

    public void Start()
    {
        tex = new Texture2D(tsize, tsize, TextureFormat.RGBA32, false);
        
        tex.filterMode = FilterMode.Point;
        colors = tex.GetPixels(0);

        GetComponent<Renderer>().material.mainTexture = tex;
    }

    void Update()
    {
        elapsed += Time.deltaTime * 0.5f;
        if (elapsed > 1f) elapsed = 0.0f;
        for (int row = 0; row < tsize; row++)
        for (int col = 0; col < tsize; col++)
        {
            colors[row * tsize + col] = new Color(0, elapsed, 0);
        }

        tex.SetPixels(colors, 0); // mipmap level 0
        tex.Apply(updateMipmaps: false);
    }
}

It's the unity example with some modifications

I tried adb logcat but I don't see any errors

[thick terrace]

it might be a problem with the material or shader rather than the texture? that code looks OK, and the empty texture if it's not being set properly is grey not purple iirc

purple usually means no shader

[vagrant spade]

Yeah, I can take a look at that, need a specific shader for Android?

[thick terrace]

not usually, are you using URP?

[vagrant spade]

I believe so, yes

[thick terrace]

can you check if it's using a URP shader?

probably worth trying to assign a basic URP material instead of whatever's there and see if the problem persists

[vagrant spade]

Actually, it doesn't have a material assigned, I guess it just generates one from whatever I'm doing there in the code

[thick terrace]

well that code isn't doing that so i don't know 😛 if it works in editor, what material is visible on the renderer when you press play?

[vagrant spade]

I just assigned a random material, let me try building

[vagrant spade]

Yeah, that seems to have been it. The editor would generate the material to make it work but on android I have no clue what was being generated. Now that I assigned a random one, it's working

I'm getting 120 FPS on a really good android, calling set pixels every frame

I have to test on lower end devices but this might be viable. It's only 128x128 though, gotta see if I can bump it up

[placid edge]

Can I populate an array/list with empty?

like if I want to store a game object on the 6th place in an array and have the first 5 just be nothing, is that doable?

[swift aspen]

Sure, just Add(default(T))

where T is the type in your list

[placid edge]

oh cool, thanks :)

[swift aspen]

but sounds more like you just want an array at that point

[placid edge]

would an array make empties if i were to store an object on the 6th place?

[swift aspen]

An array sets all indices to their default for whatever you have

I.E int array would all be 0, array of some class (monobehaviour) would be all null

[placid edge]

so what youre saying is, if I were to add a gameobject to an array, in the 3rd place, the first 2 would just be null, and could be filled up later?

[swift aspen]

yes

[placid edge]

oh its that simple

and if i were to move the object to another position in the array, there would be no problem with that either?

[gray thunder]

correct

[placid edge]

nice

[gray thunder]

Fixed size = array
Dynamic size = list

[placid edge]

oh would i have to set the size beforehand?

[swift aspen]

Yeah you need to set the size

[placid edge]

ok, fair enough

[swift aspen]

But since the exact index is important I assume that you have some restrictions on that size

[placid edge]

thanks everybody :)

yeah its a set size

[swift aspen]

Just so you don't have a size 2000 but only one index is actually used

[cold seal]

Would those transformations be correct? cluster is the parent object (Im trying to make transforms based on rigidbody position and rotation rather than transform's)

    public Vector3 InverseTransformPoint(Vector3 point)
    {
        return Quaternion.Inverse(transform.localRotation) * cluster.InverseTransformPoint(point) - transform.localPosition;
    }

    public Vector3 TransformPoint(Vector3 point)
    {
        return cluster.TransformPoint(transform.localPosition + transform.localRotation * point);
    }

    public Vector3 InverseTransformDirection(Vector3 direction)
    {
        return Quaternion.Inverse(transform.localRotation) * cluster.InverseTransformDirection(direction);
    }

    public Vector3 TransformDirection(Vector3 direction)
    {
        return cluster.TransformDirection(transform.localRotation * direction);
    }

(cluster.TransformPoint etc are custom methods that work with rigidbody and are working correctly)

[steep saddle]

I have a selectable component, but I would like the transition for a right mouse button press to behave the same as a left. What's the quickest way to accomplish this?

[slim trail]

hello

i have a problem with move towards

it works one every mob in my game but not for one boss

i tested it

compiler goes to this line

and speed * delta time is greater than 0

i lso chcked player.position

and it works correctly

someone know where's the problem?

[ebon linden]

should probably check the variable speed especially if it's serialized

i want to buy an old account for playstore
it can be empty with no games
but i just want it to allow publishing games without the new policy of 2 week testing

if anyone is interested let me know
we can also trade i've a new account (i didn't know this 2 week testing policy came)

if this is not allowed in this channel or this server, i'm sorry can delete my post

if this is not allowed where should i go to do this?

[open plover]

So I was planning to use a tweening library to smoothly edit timeScale after exiting the main menu. However, the tweening library would stop working because I set the timeScale to 0 when entering the pause menu. Is there a specific timescale used only by phsyics or do I have to set every rigidbody on my scene to static? (Note: There aren't that much rigidbodies)

[somber nacelle]

does whatever tweening library you are using not support using unscaled time?

[open plover]

ok just found about .setIgnoreTimeScale(true); ty

[compact fog]

Question for yall, Did unity change something with how you can assign things in the inspector? I am fairly new to unity and only have real experience on the latest public release, but following older tutorials and looking at packages I see that a lot of them will use the component attached to a gameobject as a variable for prefabs, for example in this code:

[CreateAssetMenu(menuName = "Impact System/Play Audio Effect", fileName = "PlayAudioEffect")]
 public class PlayAudioEffect : ScriptableObject
 {
     public AudioSource AudioSourcePrefab;
     public List<AudioClip> AudioClips = new List<AudioClip>();
     [Tooltip("Values are clamped to 0-1")]
     public Vector2 VolumeRange = new Vector2(0, 1);
 }

With the use case being you create a prefab with a gameobject that has the AudioSource component. However you can't assign a prefab to this variable because it expects a AudioSource not prefab, but clearly in the tutorials and use case of this that shouldn't be the case. Generally want to know if this was something that has changed and I should be converting these to generic game objects to use them, or am I doing something incorrectly?

[somber nacelle]

This is how it has worked for a long time. when you drag a prefab (or any gameobject) into a slot that expects a component type, it will grab the correct component from that gameobject

[compact fog]

Thats whats I figured, so does that I mean I do need to be converting the scripts like this:
public AudioSource AudioSourcePrefab; To public GameObject AudioSourcePrefab;

Then be sure to pull the component out of the prefab when i need it?

[somber nacelle]

no, the first is the more correct option. it will get the correct component from the object you drag into the slot. You almost never need a variable of type GameObject unless you need something specifically on the GameObject class and don't need to use any of the components attached to the GO

[compact fog]

Oh so you can drag the prefab into it, you just can't select it via the variable selector thing (the bullseye part)

[somber nacelle]

yes, you can drag a prefab into the slot. if it isn't showing up in the selection window then make sure you have it set to the Assets tab rather than the Scene tab. if it still doesn't show up, it's likely a bug

[compact fog]

Yeah the selector for it is just empty:

Which lead to my confusion

[pure ore]

Does anyone know how I can disable this?

[somber nacelle]

disable what, the intellicode suggestions?

[noble tundra]

Hi guys! I was trying to optimise my enemy detection code. I'm developing an RTS type game with a multiple units across the map. Currently I'm doing detection by running a Physics.OverlapSphere on a large radius every 3 seconds for each unit but It seems like this is a bit taxing and I wanted to make the checks more frequent than every 3 seconds. Is there a better way of doing this?

[pure ore]

I figured out how to. But now whenever I try to make a new line and type, it puts the new line back on the other line

I don't know how to make it stop doing that

[somber nacelle]

i have no idea what you mean by that

[pure ore]

hold on

So like with this I tried putting the line below but as soon as I completed it with a semicolon, it put it back on the line above

[somber nacelle]

check your style settings

[lean sail]

Have you tried using the nonalloc version?

[noble tundra]

I haven't heard of this

[lean sail]

The docs for the OverlapSphere even suggest it because OverlapSphere will allocate
https://docs.unity3d.com/ScriptReference/Physics.OverlapSphereNonAlloc.html

[reef garnet]

busy struggling with how to go about this but how could I have an NPC with a navmeshAgent be hit by a vehicle with a rigidbody
Trying to get this working with ragdolls
Tried adding a rigidbody with isKinematic but that brings the vehicle to a halt when the collision takes place while setting isKinematic to false

[noble tundra]

Interesting! I'll give it a try thanks

[lean sail]

Kinematic bodies dont respond to forces. If you want a navmesh agent with unique movement, just take the path and apply that to a rigidbody

Dont actually use navmesh to control it

[reef garnet]

oh so have the navmesh calculate the path and move the rigidbody along the calculated path

[lean sail]

Yes, if you're relying on the actual physics collisions then AddForce towards the next position in the path should be fine

[reef garnet]

thanks for the advice

[serene veldt]

[sly gate]

so im making a moba-like item system in my game, where you have items you character can buy that change how your character works, like for example having a different attack range every 3 attacks, considering im going to have dozens of these items, is there a way to implement this without just making if statements for each relevant item in my combat script? i cant think of any

[lean sail]

What part of this would require a bunch of if statements in the first place? Your item implementations should handle this logic and call functions to adjust the player as needed

[sly gate]

Most items dont just increase stats and have special passives that generally add more complexity to your abilities, for example, one of the items I have increases all damage of physical abilities by 15. So I'd need to put an if statement if the item is bought or not, and then apply this buff

[stone pewter]

what's the relationship between MonoBehavior's OnGUI's repaint event, Update(), and camera.Render(), if any?

do some of them trigger each other, or are they all completely independent from one another?

for context, I'm setting up a camera to only repaint when necessary (pretty much exactly how unity's scene view works), so I've got a disabled camera where I'm manually calling Camera.Render() whenever it's needed

but I'm not 100% sure how these interrelate, if I should do
if(guievent == repaint && cameraDirty) cam.Render();
or if I should put this check in Update() instead, and how that affects the OnGUI calls/drawing

[lean sail]

I understood this already, but again the items should implement this functionality, maybe through a base class or interface. Your inventory shouldnt be checking what items it has in such a way

[sly gate]

I'm not sure on how to do that

[modern creek]

How do I control a cinemachine camera system where I want to be able to set the position of a camera (say, when the user scrolls up/down with their mousewheel)? Do I need to create a "to" camera anytime the user scrolls their wheel and then set that one active (so cinemachine does the blending)?

[leaden ice]

My understanding is that OnGUI happens whenever a UnityGUI event happens... which is any of these things: https://docs.unity3d.com/ScriptReference/EventType.html

As far as I know, that doesn't include Update
But I also haven't used IMGUI in a while.

Oh wait - this one says it happens each frame so there's that https://docs.unity3d.com/ScriptReference/EventType.Repaint.html

[stone pewter]

so, it says "One is sent every frame", I'm guessing frame here means Update() unrelated to rendered frames from cameras, right?

[leaden ice]

So each frame there will be 0-n "other events" followed by a repaint event

[leaden ice]

Yeah that sounds right to me

Does IMGui ever render to a camera? Or is it always in "overlay" mode?

[stone pewter]

the runtime OnGUI I'm pretty sure is always overlay mode yeah

the editor has a bunch of local OnGUIs

[modern creek]

[sour hinge]

Hi guys! anyone have experience with PID controllers? I created a physics based movement controller and I'm using them to modulate torque to achieve a target rotation.
The idea was if quadrotor drones can do it in real life, then I certainly can do it in unity. I've attached the important bits but I'm not looking for a bug fix, I'm thinking I'm missing something completely about my strategy and I'm hoping someone can point me to the right tree to bark at.

to summarize my current implementation (which works great actually, I just feel there MUST be a more elegant way)

• determine target rotation quaternion
  This is the easy part
• determine the angle, and axis around which you'd need to rotate, to reach the target rotation.
  again I think I have a pretty good handle on this, although I still struggle with gimbal lock with my specific code.
• determine desired angular acceleration
  This is where I need help. I think first I tried just one pid controller for torque around each axis. I also tried a single controller for torque from the angle difference between current and target. both of those resulted in oscillation around the target rotation. What I finally landed on was this:

        float angleCorrection = rotationPIDController.Update(0, angleInRadians, Time.fixedDeltaTime, true); // I had to alter the PID code for this case to make it work. This is because the error in this case will always be positive.
        Vector3 omega = rotationAxis * angleCorrection;
        Vector3 localAngularVelocity = transform.InverseTransformDirection(rb.angularVelocity);
        float accelX = AVPIDX.Update(omega.x, localAngularVelocity.x, Time.fixedDeltaTime);
        float accelY = AVPIDY.Update(omega.y, localAngularVelocity.y, Time.fixedDeltaTime);
        float accelZ = AVPIDZ.Update(omega.z, localAngularVelocity.z, Time.fixedDeltaTime);

so I'm basically modulating angular acceleration in each axis. I then take these values and convert them to torque given the gameobject's inertia tensor and current angular velocity using euler's equations. The rest is a 100% physics based movement controller, with all movement done using addforce() and no setting positions! I'm quite proud of it and it'd be awesome to refine this bit and understand it better.

I understand how niche this question is but if you know anyone who you think would have good experience here please let me know!

[modern creek]

Is there a way to do raycasts with [infinite] planes? without having a GO with a collider in the scene? I want to get the world position of a click from the user's mouse

[leaden ice]

Plane.Raycast

https://docs.unity3d.com/ScriptReference/Plane.Raycast.html

[modern creek]

perfect, thanks

was thinking I'd need to be making a box collider sufficiently large to cover the whole world :p

[leaden ice]

I've actually written custom Raycasters with this before and then you can integrate it with the event system easily too

[modern creek]

oh? that'd be interesting to me because I was just in the middle of rolling my own drag handler

got some code in git or otherwise public?

[leaden ice]

Basically just derive from this class:
https://docs.unity3d.com/Packages/com.unity.ugui@3.0/api/UnityEngine.EventSystems.BaseRaycaster.html

Implement the raycast function:
https://docs.unity3d.com/Packages/com.unity.ugui@3.0/api/UnityEngine.EventSystems.BaseRaycaster.html#UnityEngine_EventSystems_BaseRaycaster_Raycast_UnityEngine_EventSystems_PointerEventData_System_Collections_Generic_List_UnityEngine_EventSystems_RaycastResult__

And plop it in your scene somewhere

In your case you basically would just take the mouse pos from the PointerEventData, do the Plane.Raycast, and dump the result (if any) in the resultAppendList

[modern creek]

hm, ok.. will have to wrap my head around it some more, but this might be useful .. i think i want a simple plane raycast with some constraints (ie, don't click "off" the world map) but it would be nice to be able to just subscribe to my own events

[leaden ice]

Hmm weirdly enough I can't even find my project that usesd it right now... I think I forgot what it was called 😢

Oh wait I found it

[winter jacinth]

Do games generally run at lower fps in the scene view/game view in the engine? I got a RTX 2070S and Ryzen 7, and when playing a simple game moving a cube around, the max i get is around 75 fps. I already played with settings in the nvidia control panel. originally it was capped at 60 fps, but i uncapped it, and now it goes around 75 fps or so. Would expect max fps for a simple game with just a cube

[modern creek]

scene view probably lots slower because it's gonna render a buncha other stuff, depending on what gizmos/etc you have enabled

wireframes, selection outlines, etc

[leaden ice]

https://hatebin.com/yqeenadjta

Found it

[winter jacinth]

Well the project at this point is basically default 3d setup. Theres just a cube and a few cube walls, all gizmos are default

[leaden ice]

Oh right I forgot I have this whole Board class... Basically that does a bunch of Plane.Raycasts inside

[modern creek]

Cool, thanks PB. Just on my way out to dinner and probably done for the day but have it bookmarked. Expect questions tomorrow. 😉

It looks like you're doing what I'm doing basically already, aside from inheriting from BaseRaycaster

[leaden ice]

https://hatebin.com/ffvlknhtqb ultimately Board.Raycast does this inside

[modern creek]

where _terrainPlane is new(Vector3.up, Vector3.zero)

I'll probably also have to do some trig to get the world position from this float

[leaden ice]

In my case: public Plane Plane => new(transform.up, transform.position); because these things can rotate

[modern creek]

since I care about the position in the unit normal plane - so (x, 0, z)

(and .. maybe weirdly? the out from Plane.Raycast is a float of the distance along the ray.. which.. I'm not sure where it originates from.. the camera position, probably?)

[leaden ice]

Yeah you're meant to use var worldPos = ray.GetPoint(enter); to get the world position

[modern creek]

oh, awesome, saves me from having to write this:

[leaden ice]

Just note that the raycast will always return an enter value, and it may be negative if the intersection happens behind the camera

so it's often useful to check the result of the raycast

[modern creek]

yeah i'll add all that error checking later

should be fine since my camera will always be y>0 but for now i'm just proof of concepting it

kinda works but now I'm gonna have to account for cinemachine moving the camera, which moves the mouse, which moves the camera......

but it's on the right track, anyway

basically i'm tracking the start world position and current world position, and moving a tracking target in the opposite direction, which cinemachine blends to

hm... maybe I could do something wonky like parenting a gameobject with a plane to the cinemachine vcam.. I dunno, maybe I'm getting too fancy and should just do "normal" panning.. ie, drag left/right/up/down and I manually move the tracking target some amount of world units instead of trying to be "diagetically accurate" and letting the user grab the map with a god hand to move it around

I've never liked the feel of games where you click on a tree, drag to the left, and the tree pans further or less than your mouse has moved

[fringe sky]

Hello, can someone explain a small issue I just got? I have a crafting system that refreshes all crafting slots to check what info they have inside right after crafting something. So I put in a "wood" item, the system shows me recipes that use wood, I craft a table which destroys the wood gameobject and THEN calls the RefreshSlots() function, the code checks the slot in which I JUST DELETED EVERY CHILD OBJECT and says "yeah there's still wood in here". I think that somehow the slots are refreshing before the gameobject is considered deleted and I don't know what to do to stop it other than maybe waiting for a single frame. Does anyone know of a more "elegant" solution? If you need to see the code, do tell me.

Also, chatGPT doesn't see any mistakes with it, so I'm super confused because it works perfectly fine when I have more than 1 wood gameobject in the crafting slot.

[cosmic rain]

Debug first

[fringe sky]

Sorry, I did debug and it is most certainly telling me that the slot with 0 children has 1 child.

[cosmic rain]

Share code

[fringe sky]

https://pastebin.com/gk6A3DSK here, these are the two problematic classes

[cosmic rain]

I barely see any useful logs in the code. Debug log more info. For example, if there are children when you don't expect any,debug the names of the children.

[fringe sky]

sure, thank you

[fringe sky]

I've been doing some testing and I am more than sure that the slots are refreshing before the object is destroyed. I think it's a Unity thing because in the code, the deletion is supposed to come before the refresh.

I found this: Actual object destruction is always delayed until after the current Update loop, but will always be done before rendering.

[cosmic rain]

It is, but the hierarchy should be updating immediately iirc.

Anyways, I wouldn't use actual gameObjects for items if I were you.

A list of simple plain classes would do.

[fringe sky]

That was my original idea, but I screwed it up since I'm still new. I just used a tutorial and have been modifying it since.

[cosmic rain]

Does your item destruction code actually run before refreshing? Did you debug that?

[fringe sky]

It doesn't. I did debug it.

Thanks for the help, by the way.

I came up with a solution though, I just add a boolean to the InventoryItemScript that says if it should be destroyed or not. I can treat it as if it were destroyed just with the bool.

[cosmic rain]

If it doesn't, then that's the problem, is it not?

[fringe sky]

Yeah that's what I've been saying.

[cosmic rain]

Then it's a problem with your code. Just make sure that you destroy the items before refresh is called.

[spice hill]

For Character Controller, is there any built in or preferred method for having a "Step Offset" for downwards steps, so that the player snaps directly to each step while travelling on downwards stairs.

My solution is just shooting a raycast ray a tiny bit further than player height, if that hits the stairs and character controller reports as not grounded, add extra downwards gravity to make player appear snapping down to the step. Though I would like to know if there's a better solution for this or not.

[leaden ice]

Use ramp shaped colliders instead of stair-shaped colliders

[spice hill]

Right, but is what I'm doing to snap the player to the ground the best solution? A ramp will be the same that by default the player will slowly fall down onto the ramp, rather than being immediately grounded to the ramp (which is what I want).

I'm trying to make a custom button that holds some extra info. I made class derived from button and added a public variable. In the inspector, all the button content shows with no problem but anything other than that doesn't show

It would be easier to just attach a second/separate script, rather than deriving Button

The Button component has a custom inspector

[open plover]

I mean it was only for reference purposes, I believe I still could call adequate methods in start

[reef garnet]

private void OnCollisionEnter(Collision other)
{
    if (IsStunned)
    {
        return;
    }

    Debug.Log(LayerMask.LayerToName(other.gameObject.layer));
    
    // NOT WORKING!!!
    if (other.gameObject.layer == LayerMask.NameToLayer("Wall"))
    {
        Debug.Log("Hit Wall");
        Destroy(gameObject);
        return;
    }

    if (other.gameObject == Player.gameObject)
    {
        CollideWithPlayer();
    }
}

Can anyone tell me why this isn't working with the wall layer

[somber nacelle]

what does the log print?

[reef garnet]

Scratch that I'm a dumbass and left the rigidbody as kinematic, PROBLEM SOLVED

[reef garnet]

name of the layer it is colliding with but it just wasn't registering the walls

but got it now

[somber nacelle]

i was not asking what it would theoretically print. i was asking for what it is actually printing to the console

[reef garnet]

nothing

[somber nacelle]

right so then next time don't assume that your condition isn't working. that was misleading because the method wasn't being called at all due to it being kinematic

your comment in the code also implied that the log was in fact working

[reef garnet]

thanks for the advice, the confusion came from the collide with player actually working, it was just the layer related code that wasn't

[rustic summit]

how can i somehow test if two intersecting collision trigger lines are perpendicular between each other?

i was thinking of somehow getting the overlapped area and testing if the area is more than that square, and i think using a dot product would be too expensive for something simple like this

[coarse dragon]

Get the rotation of both objects and check if the difference is equal to 90?

Just an idea

[rigid island]

use the dot product

float min = 1e-6f;
float dot = Vector3.Dot(direction1, direction2);
bool arePerpendicular = Mathf.Abs(dot) < min ;```

[rustic summit]

okay.. and looking at the docs i would get the rotation direction with Quaternion.eulerAngles?

wait wtf am i saying

[rigid island]

Vector2 dir1 = b-a

[cosmic roost]

Looking for suggestions on how I might handle a "negative light-source". Not an immediate need, as I need to work out a few other mechanics, but I'm trying to model the powerset of a character who can enter and exit a ghost state when no one is watching them. I can do the mechanical part of the entering and exiting, but while in that state, time stops (not difficult in this case) and the world is uniformly lit except for cones of vision, which are opaque. I could just add solid cones, but I want them to be broken up by obstacles. Something like a "negative light" could work, like a spotlight that removed light in its radius and otherwise cast "shadows" by not reducing the light behind an obstacle, but I can't find a way to make Unity do that. Lastly, I'm debating some sort of raycasting and building of an object from quads based on obstruction, but that feels like it could get really complicated really quickly.

Worse comes to worse, I can work on refining the actual time-frozen ghost world, but it would be nice to have a solution to work towards implementing.

any suggestions for saving game progress?

[lean sail]

Did you google anything related to this? This is probably the 2nd most popular topic for tutorials

[rigid island]

make a POCO class and save that to text

[rigid island]

as one who made one of those a while back , this is too true

[mild holly]

using System.Collections.Generic;
using UnityEngine;

public class Fruit : MonoBehaviour, IGrabbable
{
    
    void OnCollisionEnter2D(Collision2D other)
    {
        if(other.collider.TryGetComponent(out Player player))
        {
            player.CollectGrabbable(ref this);
        }
    }
}```
 I want to ref this class to a method so I could do is casting for making it such that every IGrabbable can have different functionality, but as you may know we cannot ref this as it is readonly

[lean sail]

Why are you trying to ref in the first place? It seems you just need to pass it in as a parameter regularly

[mild holly]

    {
        if(grabbable is Fruit)
        {
            
        }
    }``` so that I could do this in Player class

[lean sail]

What part of that needs ref?

You can just delete the ref word and itll work

[mild holly]

ohh

Thanks

[lean sail]

Ref or out means you'd be assigning something to the class that calls this code

I'm trying to make a setup where an object has different gun objects (each gun inherits the gun abstract) and I can set them in the inspector. However I can't get it to be visible in the inspector... can anyone help? (I'm hoping for a dropdown under Pistol to let me fil in bulletTemplate delay and speed)

[lean sail]

!code and also does Gun inherit from monobehaviour? It looks like it from that inspector. Meaning youd have to make a pistol component and drag it into that slot

[opaque vortex]

Is it better to go for a good script that is well written but takes me a while for my game idea, or a rough script that runs but I can code faster?

[rigid island]

option 2

premature optimization kills creative flow

nothing wrong with preplanning though, but if you're going for a quick proto idea get something working the way you want first, worry about optimizations later.. if it needs a refactor at some point, not that bad to do

[cold parrot]

there are two important principles in gamedev, what navarone said is how you get to a point where you have a fun idea, but once you have that you MUST write everything in a competent and baseline efficient way (not optimized yet) otherwise you will drown in tech debt. You cannot ever afford to make something that is shit because it needs to be done quick. The common advice is to rewrite your game (or subsystem) from scratch after prototying is done, and this seems to be the approach that is eventually the fastest. Primarily because scrappy prototyping gives you information on what you actually need, it helps you understand the problem... and nothing is worse than overengineering a solution because you don't understand the problem.

[opaque vortex]

I was trying my best to follow the practices of good clean code, avoiding repetition, too many if statements or any at all, trying to create functions that were multi purpose with generics. All of that kept time consuming, and pulling away from writing the next script. Would it be best for a rough prototype to not write in such a way, or to keep doing it? I work alone, and I honestly just want to do the job once and good. I know it will all be refactored later for optimization and improving the code, but trying to decrease the amount of refactors is what I am aiming for partially.

[rigid island]

you also would be surprised how fast you can remake the project after a rough proto was done, because you already know whats needed and wat to avoid

[dawn nebula]

How do you get a gameobject local up axis?

Is it just transform.up * transform.localrotation?

[lean sail]

Transform.up is already local

[dawn nebula]

oh, kk

[cold parrot]

transform up is not local, that would be pointless

[lean sail]

Oops I got confused with the wording

[dawn nebula]

alright so is it just transform.up * transform.localRotation >_>

[lean sail]

What result are you trying to get with that? Because im not really sure what you mean by local up axis. Transform.up is in world space. In local space the up vector would just be (0,1,0) wouldnt it?

[cold parrot]

no, your question is wrong, you dont want local you want world space, and that is what .up is

local up is just (0, 1, 0)

[dawn nebula]

So I have a sphere. I have an object somewhere on the surface of that sphere, where it's up axis is aligned with the normal. I want this object to always be looking "up" along the sphere.

[dawn nebula]

This, basically, if it makes sense.

I have the position on the sphere, so I obviously have the normal. I just don't know how to rotate it to always face "north".

Any tips? @lean sail @cold parrot

[leaden ice]

it's literally just transform.up

[leaden ice]

ok so you what you want is your character to face north on the surface of a sphere?

[dawn nebula]

pretty much yep

[leaden ice]

Maybe this?

Vector3 northPole = theSphereTransform.TransformPoint(Vector3.up);
Vector3 dirToNorthPole = northPole - characterTransform.position;
Vector3 surfaceNormal = characterTransform.position - theSphereTransform.position;
Vector3 lookDirection = Vector3.ProjectOnPlane(dirToNorthPole, surfaceNormal);
characterTransform.rotation = Quaternion.LookRotation(lookDirection, surfaceNormal);```

this is not tested

but... I think it should work

It will freak out when you're directly on either pole, for obvious reasons

[dawn nebula]

I'll give it a try. What's the worst that can happen.

[leaden ice]

your guy looks the wrong way 😄

[astral nexus]

hi, I made some very very simple Dependency Injection framework with Attributes, reflection, etc., but I have very stupid problem with it - I don't know how to gather INSTANTIATED AND ALREADY EXISTING objects at runtime inside my scenes in not dirty way, so I can populate them with their dependencies at their creation/initialization, lol
like, all I need is just to make some kind of "scene observer" that could check if Game Object is created and provide it to my DI resolver, but I simply can't get the idea how to make it in simple and semi right way (without static events, polling, etc.), like SceneContext class in Zenject (if I recall class name correctly and what it does, hehe)
maybe someone can give hints on how to make this sort of "scene observation" logic in a robust way?

[dawn nebula]

doomed

[lean sail]

I was trying to think and got stuck trying to visualize how the projection would work 😅

[leaden ice]

Why do you need a "scene observer"?

You can just store the references as you Instantiate them

[dawn nebula]

It just works.

Thanks man.

[leaden ice]

nice, I was like 80% sure it would

[cold parrot]

iirc there is a projection matrix that converts the 2D surface of the sphere into 3D carthesian space, i forgot how to do that though, sorry, its probaly just what praetor said in 4x4 form

[lean sail]

You might also need to check if that lookDirection is the 0 vector, relating to what praetor said about directly being on the pole

[cold parrot]

there is no right way to add instances at runtime to a dependency injection container, the pattern is supposed to declare how objects are created and then never changed again. You do not add instances to a container, the container is supposed to create them.

[astral nexus]

ah, I see!

[cold parrot]

what you probably want is a service locator

[plain halo]

I tried to implement something like this some time ago, but it doesn't work. If you see in the video when the ball is hit fast on the mostly horizontal axis it is as if only the collision is registered (not the script) as neither the animation itself nor speed factors are implemented.

[dusk apex]

Maybe something like this...cs Vector2 direction = playerVelocity.normalized; Vector2 adjustedDirection = (direction + Vector2.up).normalized;//Down for the top player Vector2 adjustedPlayerVelocity = adjustedDirection * playerVelocity.magnitude; Vector2 finalVelocity = minSpeedVector + adjustedPlayerVelocity; rb.velocity = finalVelocity;where you'd adjust the initial direction by combining with an up or down direction and scaling by the player's speed to create an adjusted velocity. Up being the bottom player and down being the top player.

[potent sphinx]

Does unity have built in support for social sharing?

[hard estuary]

Like sharing on facebook?

[open plover]

phones have like a menu where you choose on which app to share

I mean that

[hard estuary]

Looks like there is some support for mobiles:
https://www.youtube.com/watch?v=vTIBel9X3mQ
I haven't tested it though.

[open plover]

Ye I saw this asset but its no longer supported

[boreal jewel]

a mechaninc in my game works in the editor, but when i build it sometimes works and sometimes doesnt??

[open plover]

I will have to manually create platform specific plugins and call them from c#

[hard estuary]

Sometimes things work differently depending on which platform you're using.

[hard estuary]

Sometimes no longer supported assets are good enough to be used. Testing it out would probably take less time than implementing things by yourself. But first I would suggest searching for some alternatives.

[boreal jewel]

it works perfectly fine in editor, but in build it sometimes doesnt throw it

[hard estuary]

I would suggest checking out the game logs. Logs will be more detailed if it's a developer build.

[boreal jewel]

the code for the sword:

using System.Collections.Generic;
using UnityEngine;

public class Sword : MonoBehaviour
{
   private Rigidbody2D rb;
   private GameObject player;
   private flip pFlip;
   [SerializeField] float throwForce;
   [SerializeField] float upforce;
   [SerializeField] GameObject sword;
   
   
   void Awake()
   {
       rb = GetComponent<Rigidbody2D>();
       player = GameObject.Find("player");
       pFlip = player.GetComponent<flip>();
       rb.AddForce(new Vector2(throwForce, 0), ForceMode2D.Impulse);
   }
   void OnCollisionEnter2D(Collision2D other)
   {
       if(other.gameObject.tag == "enemy"){
           rb.velocity = new Vector2(0, 0);
           rb.AddForce(new Vector2(0, upforce), ForceMode2D.Impulse);
       }
   }
   void Update()
   {
       if(rb.velocity.y == 0){
           rb.velocity = new Vector2(0, 0);
       }
   }
}  ```

fixed it by moving the throw to update

idk why it doesnt work in Awake(), i dont really care at this point

[simple egret]

If the player is not found, calling GetComponent will throw an exception, and execution will stop right before you add the force.
Execution order can be different between the Editor and a Build, so this script's Awake might run before whatever script is instantiating the player (if applicable)

Use Awake to initialize yourself, and Start to get references from others. If you follow this pattern, everything will be initialized by the time the very first Start executes

Any hidden strategies for aiming projectiles in 3D top down space? Currently using raycasts from camera to crosshair, but that inherently means most projectiles are being aimed downwards towards the ground. Adding a height offset/any sort of aim assist disrupts 1:1-ness of projectile path to the crosshair location, which I'd prefer to avoid. Is my current implementation just the least worst choice, or am I missing something?

Maybe getting rid of the crosshair for a world space laser sight sort ray?

[spare dome]

[rigid island]

depends on the gameplay you're after really. You could easily use the target X/Z but keep for example the y target the same height as player or targets center collider for example

[plain halo]

(I overexaggerated the scaling to make it look better when the code is applied and when it is not)

[indigo cove]

fair, but since these are projectiles rather than hitscan there may not be a target at the point of the crosshair (player leads projectiles). likewise, any sort of height offset makes the projectile go above or below the crosshair location which i'd like to avoid.

[rigid island]

what I usually do is , aiming mouseScreenPos to world pos, then do another raycast direction from player to target

[rigid island]

if there are none just use the direction but keep the height at player eye level ?

[indigo cove]

yeah, but that makes it such that the projectile no longer goes to where the player is aiming/the crosshair

[rigid island]

in what way ? the aim is the targetpos - playerPos

[indigo cove]

the crosshair exists in 2d space though... it can't account for the height offset. (well it can but you'd have perform some sort of projection to snap it and wrestle control away from the player)

maybe i don't understand what you're proposing.

[rigid island]

teh cursor yes but your raycast hit, is not in the 3D world?

[indigo cove]

it is, yes, but i'm trying to preserve cursor:aim parity

[rigid island]

huh what does that mean?

I use 2 rays for a topdown, as i mentioned, The aim direction and such is done via mousepointer then after spot is found, the player raycasts from weapon to the mouse world point but keeps the height the same as player most of the time

this way your ray is straight and not pointing down from camera to world

[indigo cove]

the projectile should go to where the crosshair is

but again, i don't think there's a way of doing this practically, so maybe i should just get rid of the crosshair in favor of a laser sight ray

[mellow sigil]

Instead of getting the position by raycasting to the ground there should be a plane at the correct level and raycasting to that plane

[rigid island]

idk if this helps give the idea

you see the yellow stays at certain height if its not valid to aim at (aiming at the floor in another room)

[swift pollen]

Any Math god here? Trying to move an object (object has a life time). If his velocity is 1, the distance traveled will be 1 over one second. Given a velocityLoss parameter, it should shouldnt reach a distance higher than the one in the graph while smoothly slowing down. I'm doing this in shader graph (vertex shader). So far the issue I have is that if I set the speed to 0, it will boomerang back to initial location because position is based on time and speed. Im thinking of applying negative speed over time

[warm sage]

Hey guys, if my player has two separate state machines (MovemementStateMachine, CombatStateMachine) and both of these need to affect my animations, do I pass them the same animation controller? Should the animation controller responsible for grounded and airborne states be dealing with combat states too? I'm guessing Layers make sense for overrides, but I've never worked with animations before so I'm unfamiliar with common practices

[swift pollen]

You can create an AnimatorState class, assign them to your animator states and check at the MovemementStateMachine and CombatStateMachine from within those states and update your animator variables accordingly. Class name is StateMachineBehaviour

hey there, can someone give me some ressources to look into for hashing and salting passwords? I have close to no clue about encryption and I don't know if the threads I find online are outdated..

[knotty sun]

this is a good place to start
https://learn.microsoft.com/en-us/dotnet/standard/security/encrypting-data

[chilly surge]

Do study and understand the theory behind it, but in terms of implementation, don't do it yourself and instead use some mature and well tested solutions.

Things like BCrypt has this all figured out for you, and you just call one function to do what you want and that's it.

(But also not sure why password handling is needed in Unity, since most Unity projects are client only)

[dense rock]

wanted to make a project using a RDBMS, as I said I'm still very inexperienced. Should I not connect to the database through the client directly? what's the usual procedure?

[chilly surge]

No client should have direct access to the database.

[knotty sun]

local or networked DB ?

[dense rock]

for now local, but I guess networked later? (not completely sure what that is)

[knotty sun]

local is fine to connect direct, networked is not, should go through a backend

[dense rock]

I suppose that sounds obvious when you say it like that

[dense rock]

I got a huge lack of knowledge in backend, API all that stuff. All tutorials ever teach me about front end stuff. Are there some good ressources to learn about that?

[knotty sun]

what you will need for that will depend on your backend platform and the RDBMS you want to use

[chilly surge]

Frontend communicates to the backend via some form of API, and backend then processes frontend's requests and modifies database. What technology you use for backend and the database doesn't really concern the frontend, the frontend only needs to know the API.

[dense rock]

want to use MySQL as I got most experience with that

[knotty sun]

on which OS?

[dense rock]

it needs to be a server not a client OS

[dense rock]

yes. (ASP .Net?)

[knotty sun]

https://dotnet.microsoft.com/en-us/apps/aspnet

[dense rock]

oof. as mentioned, huge lack of knowledge haha

[chilly surge]

Probably consider something else other than MySQL unless you are locked in with that option already. MySQL is held together by duct tapes, not really what people choose for modern projects nowadays.

[dense rock]

well lets rephrase my problem. I want to make an app that manages a lot of things (D&D stuff). users can create characters, stories, etc.. What DBMS should I use, what do i need other than the unity part of my app, where can I learn about how to get it to work together?

[chilly surge]

You just need a backend that actually handles all the logic, and your frontend communicates with the backend.

How your backend stores data is an implementation detail, it doesn't have to be a database (although you probably do want to use one)

[dense rock]

what defines a backend? is that one program? is it a webpage?

thought a backend consists of a multitude of things like react or smth

[chilly surge]

Nope, and React is frontend.

[dense rock]

yeah thats just one name I remembered from some videos

so if my backend would be a dbms like Postgres, wouldnt my frontend need to connect to it directly? or are there some other apps I need to put in between?

[chilly surge]

Frontend runs on client's machine, like your Unity game is a frontend because it runs on player's machine, while backend runs on server's machine where you have full control. That's about the only difference.

No your frontend should never have direct access to database, and database is an implementation detail of your backend.

Your backend can store data in a database, or in a plain .txt file, it doesn't matter to the frontend, the frontend shouldn't know and shouldn't care.

[dense rock]

okay thats good. But what exactly could I use for a backend?

[knotty sun]

that is what the asp.net system allows you to make

[chilly surge]

The technology doesn't matter, you can choose whatever you feel like. If you want to stay in the C#/.NET ecosystem, ASP.NET linked above is the gold standard.

Otherwise practically every language can do backend and has their own solutions in their own ecosystems. You can really just choose whatever you feel comfortable with.

[dense rock]

alright thats awesome. I'll go read about ASP.Net then.

[cold parrot]

whats the data storage problem you want to solve anyway?

[dense rock]

thanks for the tip!

[dense rock]

my brain

I just have no knowledge about backend.

[cold parrot]

what does that mean?

what do you understand backend to be?

[dense rock]

I know MySQL, but not about good practice in connecting it to frontend and how to encrypt passwords exactly

[dense rock]

the thing that works between external services and frontend?

[cold parrot]

technically backend is just "everything the user can't see"

it does not necessarily have anything to do with web, servers and databases.

[dense rock]

I thought it usually consists of multiple other applications or smth. Besides years of comp sci in school and now games programming in uni I only got taught about frontend at all

[cold parrot]

your frontend also has a backend

[dense rock]

what are some things the backend usually does for apps?

[cold parrot]

its a meaningless distrinction if you think too hard about it

[dense rock]

makes sense to me

[cold parrot]

people just usually mean "backend" is "cloud stuff"

but thats just a common type of backend, not the concept itself

[dense rock]

lets say I know to write scripts to move GameObjects, calculate stuff and make classes. However, I know pretty much nothing about external services that people use for apps or cloud stuff

and I want to learn what apps are commonly known/used

[cold parrot]

so in your case, i'd try to form an abstract model of what backend means (pure theory) and then figure out the technologies for how this theory is applied to various use cases.

[dense rock]

is apps even the right term?

[cold parrot]

apps are typically things the end-user audience uses

i.e. you build an app

[dense rock]

do videos about backend in terms of web development also help me? I would guess so

[cold parrot]

but if you are the developer of some service API, this is also your "app", and your end user is another developer

[chilly surge]

^ The distinction between frontend and backend is more about what actions you can trust.

[cold parrot]

these terms are overall not very well defined

[cold parrot]

backend isn't a concept exclusive to client/server stuff

[dense rock]

can you name some specific things one uses to manage a dbms/connect it to the frontend?

[chilly surge]

Neither am I claiming it to be.

[cold parrot]

but you're talking a lot about it, so to a beginner it clouds the term (pun intended)

[chilly surge]

You are still confusing backend with database.

Your frontend connects to backend, backend does its own thing and whether it uses database or not does not matter.

[dense rock]

i thought backend would be the service I use to connect the DB to the frontend?

[cold parrot]

the backend is everything that happens before the data appears on the screen

[chilly surge]

No, your frontend talks to the backend, that's end of the story.

Whether the backend uses database or not is completely irrelevant, your frontend shouldn't know and shouldn't care.

[dense rock]

yes i understand that. I want to use a RDBMS in my backend and I wonder what services I should know about to figure out how to connect that stuff. Is ASP.Net all I need for the first steps?

[cold parrot]

ASP.NET is a framework for building web apps. are you even building a web app?

[chilly surge]

I'm under the impression that they are building a live service game.

[cold parrot]

hmm... so the issue is really that "its complicated" and there is no simple answer.

[dense rock]

kind of. user can create characters, stories and store all that info across devices

[cold parrot]

why do you want to build that backend yourself?

[dense rock]

simplest way to say it

[dense rock]

whats the other option?

[cold parrot]

playfab

[dense rock]

does that do everything?

[chilly surge]

If it's run of the mill CRUD stuffs, you can expect there are lots of existing solutions that save you the trouble of writing code yourself.

Obviously, you will be paying for that convenience.

[dense rock]

yes probably

I guess I'll make it myself. for now my project is just for university and out of fun

[cold parrot]

it can technically do everything since its just a game-specific framework on top of microsoft azure (which is a generic cloud services provider)

it has APIs for storing any kind of user data. though no relational database (because thats generally not needed)

[chilly surge]

State of cloud services nowadays: reselling cloud services with some code slapped on, for convenience.

[dense rock]

hmm i dont know. I probably want to create the backend myself

[cold parrot]

well if you also want to make a game, then you dont

[dense rock]

its more like an app

[cold parrot]

whatever it is, you generally have to do stuff that 1000s of others have to do also, so someone has made a service to just do it that you can buy.

[dense rock]

so playfab is just the answer?

[cold parrot]

well, it solves most data/server needs for most non-mmo games.

[chilly surge]

If your goal is to learn, writing your own backend is pretty valuable. If your goal is to get your product to the market fast, then you probably want an existing solution.

[dense rock]

thats what I thought

[cold parrot]

making a backend for a game yourself isn't that difficult if you don't want it to scale

and if you don't care about security

[dense rock]

scale in what sense?

[cold parrot]

concurrent users

[dense rock]

and if i care about security theres no way around purchasing stuff?

[cold parrot]

if you build it as a single-server, non-distributed monolith, its fairly trivial to do

[dense rock]

guess it's all subscription based?

[cold parrot]

but with that architecture, you cannot scale beyond the capabilties of a single machine

and if you ever want to (not that you ever need to), you would have to rebuild it

[chilly surge]

Tbf, vast majority of the backends out in the world don't have enough users to even need horizontal scaling.

[cold parrot]

today people try to sell netflix/amazon scale solutions to people who need just 0.0000001% of that power

you can go very far with a single server

they make pretty big ones 😄

[chilly surge]

It's a plague when people reach for micro services and all the cloud stuffs when they serve like, 20 customers centralized in one geographic location.

[dense rock]

how do I find those cloud solutions?

[cold parrot]

https://aws.amazon.com/

^ most of the internet runs on that

the rest runs on https://azure.microsoft.com/

other people often just resell these baseline services with added convenience

[dense rock]

thanks much for all the help. I'll look into those :)

[cold parrot]

on both you can also scale all the way down to a single weak virtual server, for free, to get started

[dense rock]

thats perfect

[cold parrot]

and you can scale that weak server from like 2 core 4GB to 192 core an terabytes of memory

[dense rock]

hoooly cow

[cold parrot]

the only gotcha is that you need to be very very very very careful with autoscaling features

can get expensive quickly if your process boosts to 100% so it can satisfy your while(true) as fast as possible

if you dont want cloud, hate amazon and keep it old-school, i would direct you to here https://www.hetzner.com/

these are more low-level offerings, more based on setting up your own servers.

less service-y

[chilly surge]

You will be very surprised how far you can go with a 5 USD per month VPS. A side project of mine for the longest time ran on a 20 USD per month VPS, and it serves over 300 million requests per month with no issue.

Oracle Cloud has some very generous free tier offerings.

If you are cheap you can sign up for free tiers on all the major cloud platforms and you have a ton of forever free resources you can use for learning/side projects, without paying a penny.

[river kelp]

I need my collision triggers to be one-directional, so I tried using a platform effector, but when I do I get an angry warning. Should I just make my own direction check in the OnTriggerEnter?

Or are there other effectors intended to use on triggers?

[dense rock]

sorry for the ping, may I ask you which VPS you are using or what you would recommend?

[chilly surge]

Any provider is fine. If you are just learning and experimenting, use the free ones from cloud platforms.

[dense rock]

is cloud platforms one provider or wdym with 'from cloud platforms'?

[chilly surge]

AWS, Azure, GCP, Oracle Cloud, etc, are all cloud platforms offered by different people.

[rigid island]

[mossy snow]

is there a reason you can't use an assembly definition reference? That's the normal way to do what I assume you want, which is add scripts from a separate folder into another asmdef so they exist within the same assembly

Hey everyone. I've suddenly found out that Chronos package has been deprecated. Are there any alternatives to it? Or have Unity introduced any better ways to control time aside from basic UnityEngine.Time? I need a tool that allows me to control multiple different time scales like in Chronos.

looks like it's free and open source, why not just maintain it yourself? This looks super overengineered to me personally though

[wind frost]

hi, I hope this is the right channel for my question: i am trying to make a player movement controller for a 2d platformer. for some reason the player sometimes gets stuck when moving in one direction and can't continue moving in that direction unless i jump or move in the other direction. what could be causing this? here is the code: https://gdl.space/liridavola.cs

[knotty sun]

not sure why this is in FixedUpdate

if (Input.GetAxisRaw("Horizontal") == 0)
        {
            if (IsGrounded())
            {
                horizontal = Mathf.MoveTowards(horizontal, 0, drag * speed);
            }
            else
            {
                horizontal = Mathf.MoveTowards(horizontal, 0, drag * speed * airMultiplier);
            }
        }

Also never check a float for equality

And you really should add some Debug Logs to see what is happening

[wind frost]

is this better?

Input.GetAxisRaw("Horizontal") >= -deadzone && Input.GetAxisRaw("Horizontal") <= deadzone

it's in FixedUpdate() to make sure the player is slowed down no matter how fast the game is running

[knotty sun]

no, should not be checking Input in fixed update

[wind frost]

i should just use the input variable i set in update, right?

[knotty sun]

yes

but this code is identical to that in Update so I dont see the need for it at all

[wind frost]

what do you mean by identical? in update i add the velocity, in fixedupdate i slow the player down if there is no input

[urban lintel]

I've been adding my game elements (card game) to a scene normally so far without a canvas or anything, and now i'm trying to make the game have some drag and drop features. I'm seeing a couple different suggestions for how to add mouse events, namely: canvas, rayscanning and just using the unity events (which seem to require a collider). Given that this is a 2d card game, is any of these options the clear choice or is there a reason to go for one over the other?

I tried messing a bit with the canvas but it was confusing me a bit with how the scale worked inside it. Colliders seem to work easily but im not sure if that's overkill given i dont actually need any collider stuff for the rest of the game. Haven't tried rayscanning but saw a few people say that it can end up being a lot of manual work

[hard estuary]

If something benefits from existing in the world, then it usually should be kept as a non-GUI object or use world-space Canvas. Examples of benefits from existing in the world:

• physics system
• depth
• perspective
• lighting
  Non-world-space GUI objects are usually meant for things that are:
• flat (there is no depth)
• have no perspective
• positioned/stretched based on the screen resolution (e.g. put in the corner of the screen or be stretched on the bottom edge of the screen)
• have pixel-based size
• somehow sorted (I would say it gets rids of so-called z-fighting)
  Also, it's worth mentioning, that GUI have some neat features like masking, layout groups or canvas scaling.

If you try hard enough, you will be able to reproduce things usually used in one system in another one. Using world-space Canvas is a way of mixing perks of both systems.

[urban lintel]

I see I see. I don't have any physics, depth or lightning (though the latter could be nice to do later but maybe I can just fake it since it's 2d anyway). I found a similar open source example online that seemed to do pretty much all in canvas so I might just try that after all. If it doesn't work out for some reason, hopefully refactor doesn't end up being lethal

[stone pewter]

hmm is there a nice way to reference assets from a static context in unity, both in editor and at runtime, without relying on AssetDatabase in editor code, or Resources at runtime/editor?

[knotty sun]

explain static context

[stone pewter]

I'm making a custom Handles.PositionHandle() that's supposed to work at runtime (in my builds) as well as in the editor, and it has dependencies on a few shaders

(and might have some other dependencies down the line)

(I know there's Shader.Find for the specific case of shaders but I have other things I want to reference too)

[knotty sun]

well you could maybe use streaming assets and webrequest but asset bundles/addressables is made specifically for this

[stone pewter]

hmmm I've never used addressables, I'll look into it!

how does it handle build stripping?

do I need to explicitly tell unity "include all these addressables" or does it detect which ones are fetched from code from the string directly somehow?

oh boy this generated a gazillion SOs in AddressableAssetsData lol

so I have kind of a weird use case for how I'm building this project, would these file interfere with user's project if I use these in a unity plugin, and they install my plugin?

this seems wayyy to big of a system for what I'm doing I think

I thiiiink the easiest solution is for me to assign to a static field from a unity Object, where appropriate

and then just assume it's been assigned from my static functions

[upper pilot]

How do I pass Coroutine as a parameter while keeping its reference?
It seems to make a new reference, do I need ref keyword?

    private void ChangeVolume(AudioSource audioSource, Coroutine coroutine)
    {
        if(coroutine != null) StopCoroutine(coroutine);
        coroutine = StartCoroutine(ChangeVolumeOverTime(audioSource, audioSource.volume, volume, time));
    }

I want to stop previous corotutine and start a new one, coroutine is a variable in this class, but I have multiple(for each audio channel) so want to reuse this function and pass audioSoruce + coroutine.

[knotty sun]

no, Coroutine is a class

[upper pilot]

    Coroutine musicVolumeCoroutine;

I meant a reference to the instance of that class then

[knotty sun]

how do you set that variable

[upper pilot]

here

I am passing it to this function

[knotty sun]

well StartCoroutine will make a new instance

so pass it as an out variable

[chilly surge]

You can use ref yes, but I'm not sure that's a good idea.

[upper pilot]

yeah I needed to use ref

[knotty sun]

you cannot use out, because you are stopping first, wont work

[upper pilot]

it works

Yep it works exactly as I want it to work

I didnt know that I needed ref for Coroutine 😮

[knotty sun]

why pass it as a parameter at all?

[upper pilot]

so I can reuse that function

Since I have 3 separate coroutines and 3 audio channels

so I can control their volume over time separately

I could also pass enum and do it this way, but I prefer this way.
Unless there is a good reason to not use it

[chilly surge]

I don't have a strong opinion, but I can't recall a single case that I've used it despite knowing it.

[open plover]

I have two gameobjects with a float endTimer. There also is a barrier with a proper tag so that I can check*** if a gameobject stays there for long enough***. In CollisionStay, endTimer is += .TimedeltaTime'd. I also have a coroutine. A single gameobject correctly works. However, when two gameobjects stay in the barrier, the second gameobject's endTimer at some point stops increasing. This is very close to my coroutine's executing time and when waitforseconds ends the endTimer correctly works again. Other things are affected by this as well. I originally had a circle count down timer with its fill method set to radial 360. I noticed the circle's fill amount would freeze at a value then continue to increase as soon as the coroutine's waitforsecondsends. Why does this happen?

[open plover]

Update: It happens whenever there are multiple gameobjects in the scene, not just in the barrier. Is this something to do with oncollisionstay?

[steady moat]

As far as I know, collision stay work as intended. However, you could try to use Enter/Exit and see if it works. (Just be aware that spawning object or/and destroying might result in one of the two event not being called - I am not sure which one)

Also, if you have an issue, try to remove coroutine. It does not seem to be made for what you are doing. Coroutine are usually fire and forget, not made to track the state of an object.

[open plover]

The coroutine is on a seperate script, in fact I use it to spawn the gameobjects with a delay

[steady moat]

Then they seem to be unrelated ? I though you were using coroutine to keep track of the time.

Also, beware that coroutine are disabled when object are deactivated.

[open plover]

Like I said, the gameEndTimer that I += Time.deltaTime stays constant at some value at some point, then increases as intended after the waitforseconds in the coroutine ends

Anyone knows how to unlock tile color lock?

[jagged plume]

Anyone knows if this is wrong (initializing a dictionary of dictionaries)

[hard estuary]

I think it should work. I'm more of a fan of things that can be edited from the inspector, but doing it from code can be good enough for smaller projects. However, I wouldn't recommend using strings like that, because it's easy to make a typo, especially if someone means to use the same string multiple times. Declaring those as constants will make it less likely for typos (and bugs) to appear.

[jagged plume]

noted for the strings

but I get a Null Instance Error

so I think the initialization must be wrong somehow

[hard estuary]

Tested similar code:

var dictionary = new Dictionary<string, Dictionary<string, float>>()
{
 { "test", new Dictionary<string, float>() { { "test1", 1 }, { "test2", 2 } } },
 { "test2", new Dictionary<string, float>() { { "test3", 1 }, { "test4", 2 } } }
};

Seems to work fine. I suggest debugging if SetMineralSpawnProbas is invoked.

[jagged plume]

Added

[jagged plume]

Actually, the problem is that i had a method at start which called the dictionary and I think it didn't have enough time to initialize

causing the NullReference

[fringe ridge]

onClick.AddListener(() => GridManager.instance.StartPlacing(buildings.buildings[i])); Any idea why this throws Index out of bounds only when pressed? There is no way it is out of bounds, because im looping until i < buildings.count

Is ScriptableObject messaging as a core of a codebase aka "ScriptableObject architecture" worth it now for any degree?
I never tried it for a full project, but I see some very cool pros of using it, but painful cons too. Like without a lot of editor scripting it can be a huge pain to manage it and a lot of manual referencing these SO objects in Inspector
I'm very bad with editor scripting, so it's my main concern about it and the stopping factor (especially that tooling tutorials is quite rare/outdated or I'm bad at searching, lol)
But, I still wanna try it somehow for one or two projects, because I like ScriptableObjects and the idea of functional ScriptableObjects, not just data holders
It's sad that Unity's Chop Chop is gone into the void, heh

[jagged plume]

This works actually

the syntax was sound and it was really the concurrent Start() calls in which the 1st called the dict before initialization completion

thanks man for the tip on string constants

I had a typo somewhere I think also

The more repetitive and modular game mechanics are, the more convenient Scriptable Objects are. You don't need to know how to code editor to manage scriptable objects, default inspector is good enough. I suppose custom inspectors could do a good job if you need some extra validation.

Hello, I have this problem where when I want to activate my dash/dodge function, it instantly moves the player instead of smoothly moving it forward. Is it possible to fix this?

Here's my code

    {
        isDashing = true;
 
            // adjust this value to change the dodge speed
            float horizontal = Input.GetAxisRaw("Horizontal"); 
            float vertical = Input.GetAxisRaw("Vertical"); 
            direction = new Vector3(horizontal, 0f, vertical).normalized; 
            float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y; 
            float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime); 
            transform.rotation = Quaternion.Euler(0f, angle, 0f);  
                    
            Vector3 moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
            controller.Move(moveDir.normalized * Dodgespeed * Time.deltaTime);
            //dodgeDuration += Time.deltaTime;
           // yield return null;

  
        yield return new WaitForSeconds(dodgeDuration);
        isDashing = false;
    }
       ```

[leaden ice]

The code is only calling Move one time

If you want something to happen over time you would need to move over the course of multiple frames

[dusky tulip]

How would I go about that?

[leaden ice]

With a loop in your Coroutine with yield return null, or with Update

Anyone know why my UI sliders onValueChangeEvent, when calling a method, some of them require me to type a value and others don't? In my mind the value that gets sent should be the sliders value....

The one on the left works how I expect but then I set up another and it's expecting me to send a hard value

these are sliders for Hue, Saturation, and Value

[knotty sun]

you have selected the wrong one from the method dropdown

i want it to be like when you're talking to an npc in a game and the text comes up letter by letter almost like typing and you can skip this "typing" by pressing a certain button, idk if that makes sense but if anyone knows how to or has like a tutorial they can send me on how to that'd be awesome

if you have to call something so often would worry about your memory allocations and if you can do them upfront and reuse amung other things and just ensuring you are not doing more work then required

[paper tree]

for now im fine with memory just need to care about time that happens so looking for possible adjustments

[jagged plume]

Assets\Scripts\WagonManager.cs(49,10): error CS0305: Using the generic type 'IEnumerator<T>' requires 1 type arguments

I don't get the issue

[quaint rock]

what are you using statements

[jagged plume]

like when we start a coroutine we just use private IEnumerator functionName() no?

[paper tree]

(you could show which line is 49 :D)

[jagged plume]

oh it's the private IEnumerator line

[quaint rock]

yes i know what are your using statements at the top

[jagged plume]

using System.Collections.Generic;
using UnityEngine;

do I need something else?

[quaint rock]

add System.Collections

[jagged plume]

oh okok

I'm doing a game jam rn and they made me move to Unity 6000

it used to be automatically added before

[quaint rock]

this would have nothing to do with the unity version

but yeah because you only had System.Collections.Generic it was tryhing to use IEnumerator<T> instead of IEnumerator

[jagged plume]

I mean in 2021 when I create a MonoBehaviour Unity automatically adds those using statements:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[jagged plume]

Thank you for the info !

[quaint rock]

you can change what the defaults are

[jagged plume]

okok

[quaint rock]

also doubt it included generic

[jagged plume]

100% it does

the three statements

I have a few scripts in which I wrote only a few lines of code and would have never changed the using statements

E.g. this from another project

[quaint rock]

C:\Program Files\Unity\Hub\Editor\2020.3.44f1\Editor\Data\Resources\ScriptTemplates

in that location you can define the templates for the various new script types,

obvisuly adjust the path for your OS and unity version

Hello! I have a heavy lag spike for several seconds when I spawn 100 enemies at once. profiler says the physics 2d find new contacts is the problem. I don't get it, since I removed ALL possible collisions via collision matrix. What is the fix for this?

[hexed whale]

tried both kinematic and dynamic rb 2d setting. Same heavy lag spike.(Using Unity 6)

Randomly started getting these errors on VS2022. I am 100% sure the TMPro pacakge is installed on the project. It was working fine a couple of days ago but now VS intellisense doesn't pick up these packages. Anyone know why this could be? I'm not sure if its a VS issue only or a Unity issue.

[leaden ice]

1. Show the full error messages
2. Are these errors only in VS, or are they in the Unity console as well?

[torpid beacon]

VS only. The intellisense seems to be the one having the issues but other projects don't have the same issue.

[quaint rock]

any errors in unity?

[torpid beacon]

No Unity errors

[leaden ice]

Then you just need to regenerate your project files

Edit -> Preferences -> External Tools -> Regenerate Project Files

[torpid beacon]

I tried that already even with built-in packages. It doesn't help

[leaden ice]

Always works for me

¯_(ツ)_/¯

do you have the correct package isntalled for vs support

otherwise re-set up the VS integration

Hey yall, I have a menu scene. It can't be loaded at the same time as my main scene because they both have EventSystems and unity freaks out. I have a loading screen scene as well, but how can I tell my loading screen scene which scene to load?

I'm just confused about how I'm supposed to pass data between scenes

unless I'm going about this incorrectly

[quaint rock]

what most people do is just only have 1 EventSystem in there whole game

its part of the first scene to load, and has DontDestroyOnLoad on it, then never have a EventSystem in a other scene

[jolly kettle]

I'll try that out.

[quaint rock]

i tend to have a Init scene that loads first and contains all the stuff that lives for the whole duration of my game, like the event system

[jolly kettle]

what else would you put in there? I can think of much besides maybe the global postprocessing volume I have

because that'd be active on the menus and such

[rigid island]

for me, the usual ones are Game Managers and alike

gobal Post Process is good too

[jolly kettle]

would a loading screen be appropriate instead of making it a whole new scene?

my initial thought was having it be part of the menu scene, but I need to be able to use it even when the main menu isn't active

[rigid island]

no you don't have to make it a scene but its easier to carry over that way

a DDOL does on its own anyway. Any DDOL is part of the DDOL scene which is seprate anyway

[jolly kettle]

I use additive loading for my game

manually unloading and loading stuff

[rigid island]

I meant more for like data you dont want destroyed going into a new scene

[jolly kettle]

ah yea that tracks

I assume the gamemanager in the init scene would have a Start method that enables the main menu or something, then?

given that each time you load the game you'll probably want to load into the main menu

can't think of too many cases where that isn't true

[rigid island]

thats up to your design , you wouldn't necessarily do it in GameManager but you can.
My gamemanager doesnt deal with menus, thats what my MenuManager does 😏

[jolly kettle]

ah

same concept though

[rigid island]

yeah sure if you plan on having a boostrapping scene

some times its also easier to have a specific prefab that has everything you need and it just gets placed in whatever scene you just loaded and use singletons to destroy any copies

[jolly kettle]

I cant think of what else I would do

you have an init scene that loads first

how does it load other scenes

other than a script that loads another scene on start

[rigid island]

it usually automatically goes into the Menu

[jolly kettle]

yea that's what I'm imagining

[rigid island]

yeah through a script like you said

[jolly kettle]

if you couldn't tell I'm not a programmer 🥴

[rigid island]

hehe its no worries, the upside, there is not really a wrong way to do this. You can approach it however makes most sense to you

if right now your issue is having 2 event systems then you should only have 1 active UI Manager type or just dont carry the second scene w event system

or leaving 1 in each scene is fine, just carry other things in a DDOl scene but not event system

[nova raptor]

would anyone know why the audio isn't playing? from my logs, it looks like the dsp time isn't updating, but I have no clue why that could be. Even disregarding everything else, at the very least PlayScheduled() should work right?

for context, startBeat is 1, and firstBeatOffset is 0. I already know for certain that TimeInBeatsToTimeInSecs() works

    void Update()
    {
        // Update the DSP time
        dspTime = (float)AudioSettings.dspTime;
        print("dspTime: " + dspTime);

        if (_songPlaybackScheduled)
        {
            if (dspTime >= dspStart)

                isPlaying = true;
                _songPlaybackScheduled = false;
            }
        }

        if (isPlaying)
        {
            // How many seconds since the song started
            songPosSec = dspTime - dspStart - _firstBeatOffsetSec;

            // How many beats since the song started
            songPosBeat = songPosSec / secPerBeat;

            lastPosInBeat = posInBeat;
            posInBeat = songPosBeat % 1f;

            if (songPosBeat >= Math.Ceiling(startBeat) + _metronomeTally)
            {
                if (metronome)
                {
                    metronomePlayer.Play();
                }
                _metronomeTally++;
            }

            RhythmInputManager.instance.beatText.text = "Beat " + songPosBeat.ToString();

        }
    }

    public void StartPlayback(float startBeat)
    {
        // Get the audio source attached to the conductor
        audioSource = GetComponent<AudioSource>();

        // Calculate seconds per beat based on the current BPM
        secPerBeat = 60f / bpm;

        // Calculate offset
        _firstBeatOffsetSec = firstBeatOffset / 1000f;

        // Start music playback
        PlaySong(startBeat);
        print("playing audio");

        audioSource.clip = song;

        // Set the time where the music starts
        dspStart = (float)AudioSettings.dspTime + 2 * dspSizeInSeconds;

Im still a bit confused about how the main menu would operate. It needs to have a button that calls a script, but I need to disable the main menu before I can even load my first level. So it disables the script that it's calling and then breaks itself.

But I also can't have it refrence/call a script or gameobject in another scene

[rigid island]

I don't understand what you mean
" but I need to disable the main menu before I can even load my first level"

also why does it matter if its the script from menu scene gets disabled

[jolly kettle]

the main menu is a scene that loads in

it has a button that calls a function from a script

if I disable the main menu scene, it disables the gameobject that has the script on it and then breaks itself

[leaden ice]

why does it break?

there's no problem calling a function on a disabled object

[rigid island]

also by main menu do you mean like a pause screen or a level selection type deal?

[leaden ice]

also - you can and should separate the visual aspects of things from the other parts

[jolly kettle]

it's not disabled its entirely unloaded

because I unload the scene

[leaden ice]

so 0 you can disable the visuals and leave the rest alone

[leaden ice]

ok that's a different story,

So you need to rearrange some things there

Clearly you can't leave the button listener on an object that gets destroyed.

the listener can be on the same object as the button instead for example, or some other object entirely, that doesn't get unloaded

[jolly kettle]

the button gets unloaded

its part of the menu scene

[leaden ice]

then it's not a problem

if the button gets unloaded nobody can click it

[jolly kettle]

you are misunderstanding

the button unloads when the main menu is unloaded. If I attach the scene loading script to the button it'll unload itself as soon as I call the script to load the scenes

[leaden ice]

Im still a bit confused about how the main menu would operate. It needs to have a button that calls a script, but I need to disable the main menu before I can even load my first level. So it disables the script that it's calling and then breaks itself.
You said this - which implies that the button is the thing that causes the code to run

[jolly kettle]

it is

[leaden ice]

Why is that a problem?

You keep saying "it breaks" - which is very vague

be specific

[jolly kettle]

because that script has a coroutine in it that needs to keep running until the main scene is fully loaded, at which point it unloads the loading screen scene.

if I unload the main menu scene before that, then the loading screen never unloads and it's just stuck on the screen forever

[leaden ice]

Why don't you provide all these important details up front instead of making us guess lol

start the coroutine on a DDOL object

A DDOL singleton that handles scene loading etc is a good idea in general

such a thing wouldn't/shouldn't be directly part of a menu scene

except perhaps as a bootstrapping device

[jolly kettle]

how would I call it from the main menu then

[leaden ice]

By... calling it?

[jolly kettle]

I thought unity didn't support cross scene references

[leaden ice]

MyLoadingManager.Instance.DoSomething();```

[leaden ice]

of course it does

just not in the editor

you can do anything you like in code

[rigid island]

static instance will help with that

https://unity.huh.how/references/singletons

[leaden ice]

Have you never worked with the singleton pattern before?

[jolly kettle]

dawg I'm a 3D artist

idk what any of this shit is

[rigid island]

why are you in #archived-code-general not #💻┃code-beginner lol

[leaden ice]

Is there not a coder on your team?

[jolly kettle]

I am my team

[rigid island]

start simpler than what you're doing now then

[leaden ice]

yeah

making a loading screen is a somewhat intermediate task

[rigid island]

this^
n loading and unloading scene, I didn't even touch 1 year into unity as a beginner

[jolly kettle]

I'm more than a few years into Unity

It's only become an issue because I'm trying to do a bunch of additive scene loading

[rigid island]

yeah but coding

[jolly kettle]

instead of just having everything in a single scene

[rigid island]

yeah like mentioned async loading and unload scene is not exactly beginner stuff esp if you don't know any of these terms

learn for example singleton pattern and how it can be used. Better overused than trying to jump into overcomplex system

typically need manual loading/unloading scenes for specific use cases , you don't need that here

[quaint rock]

its just breaking the problem down into steps

i keep my loading screen as part of my init scene so i can display it when ever i want and have it cover teh screen while i unload and load stuff

[nova raptor]

Anyone?

[spare dome]

if someone knows they will get to you

[dusky tulip]

is there a way to change the Image fillAmount value range to 1 to 100 instead of 0 to 1?

[rigid island]

just divide the number you input in
image.fillAmount = yourValue / 100

[dusky tulip]

Lemme try this

[dusky tulip]

worked, tysm

[quaint rock]

when dealing with percentages in code its pretty common to always store them as 0 to 1 values

then simply multiply by 100 if you want to display it to the user as a 0 to 100 number

the math with 0 to 1 values is easier in most cases

[rigid island]

indeed prefer normalized values myself

[quaint rock]

yeah want to scale a value, its just a simple multiplication now

[elfin tree]

@leaden ice Hey I saw a forum post where you were talking about snapping objects together, which you seemingly had done a few times, do you think adding colliders for the snap zones on top of a snap point to make sense? Or did you usually use a different approach?

Also curious if anyone knows anything that exists that already does that before I start making my own

[leaden ice]

It really depends on the exact behavior you're going for

In my case I only had one collider per object

iirc

[elfin tree]

Yeah I guess it can go many ways, was hoping to have minimal tuning to do for each different object since they can be of different shape

I think I'll just go for it and we'll see, it might not be too hard

[upper pilot]

Hey, is it possible to change volume of audio clip(not audio source/channel) in a script?

I am using Quaternions for my mouse movement, how would I, through code, make it so the CharacterRotation quaternion faces a certain position? Say I had a gameObject and I want to set CharacterRotation to another variable to make it look in the direction of gameObject.localEulerAngles.x

 public void Rotation(Transform character, Transform camera)
 {
     CharacterRotation *= Quaternion.Euler(0f, MouseX, 0f);
     if (UseHorizontalClamp)
         CharacterRotation = ClampYAxis(CharacterRotation, -HorizontalClampValue, HorizontalClampValue);
     character.localRotation = CharacterRotation;

     if (camera)
     {
         CameraRotation *= Quaternion.Euler(MouseY, 0f, 0f);
         if (UseVerticalClamp)
             CameraRotation = ClampXAxis(CameraRotation, -VerticalClampValue, VerticalClampValue);
         camera.localRotation = CameraRotation;
         Vector3 localEulerAngles = camera.localEulerAngles;
         localEulerAngles.z = 0f;
         camera.localEulerAngles = localEulerAngles;
     }
 }

[rigid island]

I think you want ?https://docs.unity3d.com/ScriptReference/Quaternion.LookRotation.html

[lean sail]

yea LookRotation or transform.LookAt would solve that part of "faces a certain position"
though you should just use cinemachine. that whole part of reading the euler angles, setting Z to 0, and then assigning it back looks very questionable. im not really sure why you're using both quaternion and euler here

[pure ore]

I don't know why everyone keeps demanding I use cinemachine. I'm a coder, I want to make my own solutions, to learn

[rigid island]

just because you want to create your own car as a mechanic doesn't mean you have to learn how to make a tire from scratch etc.

[leaden ice]

As a learning experience is one thing. But if you want to make a game, Cinemachine is a huge time saver as it already accomplishes 85% of camera needs out of the box

If you want to make your own solutions to learn, why use a game engine at all? Why not write your whole game in assembly from scratch?

There's always some balance.

[lean sail]

🤷‍♂️ no ones demanding anything. im not your boss, doesnt affect me at the end of the day. Everyone talking in this channel is a coder
its a premade solution that works well and has MANY features. and its made better than what you or I will ever create

why not start learning soldering so you can make your own PC?

[pure ore]

I guess that's true. I mean I know about game developers who made their own functions for cutscenes before Timeline was a thing, but now after Timeline was released, they started using Timeline

[void basalt]

I've used unity for about 6 years now and I've never used cinemachine.
If you prefer to write your own tools, do that.

@leaden ice So I did most of it, only oversight right now is that my snapping colliders are all triggers so that does'nt work, should I just use normal colliders without rigidbodies?

[lyric parrot]

i need help inportng a map

[leaden ice]

my snapping colliders are all triggers so that does'nt work
I have no idea what a "snapping collider" is?

should I just use normal colliders without rigidbodies?
Almost certainly not

Sorry I don't know what the context of this is really

[elfin tree]

I made a thing that snaps objects together, each objects has colliders on snapping ends, and when two of those colliders collide the snapping logic happens, rn I'm just having issues with having the collision or the OnTriggerEnter register

[leaden ice]

OnTriggerEnter requires at least one of the objects to have a Rigidbody, and for the colliders in question to overlap

you definitely don't want to use a non-trigger collider here, since you want it to happen when they're close by, not touching

[elfin tree]

tyvm, all i needed was rigidbodies

[jolly kettle]

figured out singletons and async loading. Thanks for the help.

void Move()

    float verticalInput = Input.GetAxis("Vertical");

    // Get the player's forward and right direction
    Vector3 forwardDirection = transform.forward;
    Vector3 rightDirection = transform.right;

    // Calculate movement direction based on input
    Vector3 movement = (forwardDirection * verticalInput + rightDirection * horizontalInput).normalized;

    // Cap the movement speed
    float maxSpeed = moveSpeed; // You can change this to your desired max speed
    Vector3 desiredVelocity = movement * moveSpeed;

    // Apply speed cap
    if (desiredVelocity.magnitude > maxSpeed)
    {
        desiredVelocity = desiredVelocity.normalized * maxSpeed;
    }

    // Only move if not sticking to a wall
    if (!isStickingToWall())
    {
        // Apply movement
        playerRigidBody.MovePosition(transform.position + (desiredVelocity * Time.deltaTime));
    }

    // If no vertical input, clear the vertical velocity
    if (verticalInput == 0)
    {
        playerRigidBody.velocity = new Vector3(playerRigidBody.velocity.x, playerRigidBody.velocity.y, 0); // Stop vertical movement
    }
}

How do i get the player to stop moving when i let go of the movement keys?

[lean sail]

is this AI code?

if theres no input, then that desiredVelocity should be the 0 vector. you should use that desired velocity to set the velocity. Using both MovePosition and setting velocity isnt the best idea

Hello. I've recently (yesterday) started to learn reactive programming after watching git-amend video about R3. But I'm usually learn by performing certain practical tasks with GPT or Claude, and since R3 is so recent, Claude have no idea about it (it knows UniRx, but from what I get it's fairly different). I loaded documentation in the Claude project, and it is able to generate working code, but I have the feeling that many of its actions are suboptimal and I have no expertise to evaluate it myself. Reactive programming is absolutely freaking great, I love the paradigm, but it's no use for me since I have barely any idea how to learn it quickly and efficiently. Do someone have any relevant experience in overcoming similar issues?

[solid relic]

Maaayyybeee.. ahaha

I'll give that a go soon

Sorry, we don't help with AI code.

How can TMP_Inputfield treat multiple characters as one character, similar to in the Discord chat box with '@xxx', where it is considered as one character and can be modified as a whole?

[rigid island]

maybe links in rich text?
https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/manual/RichTextLink.html

[raven void]

However, it still cannot be handled as a whole. What I'm thinking is to generate sprites in real-time based on the text to handle it. But I'm not sure if it is an efficient way to do it.

[rigid island]

how do you want to separate the text? maybe regex or something

or separate the words by whitespace then process only the ones that begin with @.
no idea what you mean by "handle as a whole" though

[raven void]

For example, the "@lazyboy" in the image can be clicked with the mouse, formatted as bold as a whole, and when deleted, it will be deleted as a whole.

hi, i am using addressables to load and unload some prefabs, i expected it to unload with ReleaseInstance() method...Yeah it works, all the assets that was supposed to be unloaded are unloaded from memory, but something called "UNTRACKED" and "UNKNOWN in native section" is taking up almost same memory space as the unloaded asset...Ultimately the memory is not being freed up, what to do in this case?

[cosmic rain]

Are you testing in the editor?

[warm badger]

i built my test project for windows, and tested via memory profiler

[cosmic rain]

It could be that unity just reserves that memory for future use. it depends a lot on how their allocators are implemented. Does the consumed memory keep on growing over time?

[warm badger]

it grows a little bit over a period of time with a decreased rate

but my main focus was to free up memory whenever i wish to unload things, but it doesn;t seem to work as i expected

[cosmic rain]

It's fine if it reaches a peak point that it doesn't go over eventually. Otherwise you might have a memory leak.

[cosmic rain]

I see. Might want to post on the forums for a clarification. Unity should be more transparent on what that memory is used for.
Though, it could be some plugin or asset, that allocates memory sneakily.

Are you allocating native memory anywhere in your code?

[warm badger]

when i don't load anything, the unknown and untracked section remains low in size...whenever i load, both section grows and consumes memory nearly same as my loaded asset...although my main prefabs and things related to that loads and unloads correctly

[cosmic rain]

Then it could be some code on the loaded objects that allocates.

[warm badger]

using UnityEngine;
using UnityEngine.AddressableAssets;
using UnityEngine.ResourceManagement.AsyncOperations;

public class PerformanceOnSizeTest : MonoBehaviour
{
    AsyncOperationHandle<GameObject> handle;
    public string prefabToInstantiateAddressableKey;
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Q))
        {
            handle = Addressables.InstantiateAsync(prefabToInstantiateAddressableKey);
        }

        if (Input.GetKeyDown(KeyCode.A))
        {
            Addressables.ReleaseInstance(handle);
            Resources.UnloadUnusedAssets();
        }
    }
}

here it is, so simple, just to test, am i doing anything wrong here

[solid relic]

Alright, I'll remake the movement script myself. What do you think is the best way to move the player? E.g Addforce()

[cosmic rain]

Just as a test, try resetting the handle reference to null after unloading.

[warm badger]

like "handle = null" ?

[cosmic rain]

Also, what I meant is a code on the loaded object that could be running on awake, start or other unity callbacks could be allocating memory.

[cosmic rain]

That's comparison.

handle = null

[warm badger]

shouldn't i use ReleaseInstance() ?

[cosmic rain]

You should. But you should also reset the handle reference afterwards.

[warm badger]

it says it is a non-nullable value type

[cosmic rain]

Ah, is it a struct? In this case it might be fine.🤔

So, as I said, that memory is likely not related to addressables directly.

Might also want to read the manual page on memory management with addressables. There seems to be a few important points:
https://docs.unity3d.com/Packages/com.unity.addressables@2.2/manual/MemoryManagement.html

i will look into it, thanks...

but still, isn't there any solid solution to this minimal test scenerio

[cosmic rain]

What exactly does the prefab have attached to it?

[warm badger]

an environment package i download from asset store for test

https://assetstore.unity.com/packages/package/36897 this one

[cosmic rain]

And you're loading the whole asset?

[warm badger]

i opened its demo scene, turned everything from the scene to a prefab, then put that into the addressables group

[cosmic rain]

Hmm... I don't think that counts as a simple testing case. A simple testing case would be a one GameObject prefab with a sprite renderer or something.

[warm badger]

i should try that way then, i will let you know the result

[mellow sigil]

Completely off-topic but wow whoever made that boat model has apparently never seen one in real life

[warm badger]

this time i just used one modified plane with lot of vertex and one material...still no good

before loading the asset -> 169mb
after loading -> 207mb
after ReleaseInstance() -> 210mb

There's a channel for #📦┃addressables with pinned msgs, probably best to be in there, asking and reading the pinned

I am working on a package, is there way to reference actual project code? I know its kinda wrong way around but i kinda need access to "shared" code that is generated.
generator creates files i need to use in package but those files are generated based on Project files and they do reference them.

[leaden ice]

Put the code you want to access in a separate assembly.

Reference that assembly from your package

But yeah it's kinda backwards and rarely needed

[steady moat]

You cannot free a specific asset in Addressable.

If an asset is no longer referenced, indicated by the released status and disabled text in the Profiler module, this doesn't mean that Unity unloaded that asset. A common applicable scenario involves multiple assets in an AssetBundle. For example:

This is one of the reason why you need to make your addressable package correctly.

Question, I have a NavMeshLink with Auto Traverse Off Mesh Link = false (and updatePosition = false), but sometimes (not always) the navmeshagent position automatically teleports to the other extreme of the link.
Why that happens? How can I fix that?

Ok

What the best approach for object pooler class + pooled object and keep SoC?
What I did is:
BallManager holds the ObjectPool<Ball> and some utils method to handle and check all the balls.
Balls instead of destroying themselves invoke an event passing themselves, this event is listened by the manager, getting the ball and releasing it to the pool.
Is it the correct approach?

[leaden ice]

Sounds fine?

[stark plaza]

Good 👍

Injecting the pool or the ball manager to the ball to let the ball call the release method would not be good

Hi suppose you have a list of points (Vector2) and you want to get the nearest one to another point. So you iterate through the list recording the closest one. Is there a name for this pattern/algorithm? Also I never did points.OrderByDescending(v2 => GetDistance(v1,v2)).First(); as stackoverflow suggests because I figured it must be slow to sort when you just need to iterate through once - any one do that?

[hexed pecan]

I would just use the first option. I doubt that Linq can be any faster than that

[placid summit]

Yes I do, I was just thinking how often I repeat a similar pattern!

[hexed pecan]

Could make it into a helper function

[placid summit]

Ye swas thinking this - would be much cleaner

Any tips about how to attenuate sounds given obstacles? I'm not sure if I should throw raycasts from the sound source and calculate how the sound bounces from objects until reach the player. 🤔

[hexed pecan]

There are packages for this, such as Steam Audio

I think Oculus and other VR devs provide those too

If you wanna do it manually, portal-based occlusion could work

If you go with raycast route then its good to know that RaycastCommand exists. I profiled it a bit in my scene and I started getting performanve benefits at around 100 raycasts, while completing the command immediately. This would ofc be improved if you let it run for a frame before completing

Steam Audio went open source some time ago. Gotta examine it 👀

[neon plank]

I was thinking adding a bake process.
In the editor I would divide the world in a grid, and for each cell in the grid I would throw thousands (or millions, not sure) of raycasts towards all directions, and more raycasts from each hit as the sound bounces.
Then I would have a dictionary or something more optimized which maps each grid's slot with each other, and count the amount of rays (taking into account their intensities) that reach this slot.

Thought I would check the Steam Audio. I wonder if it works with FMod which we already use.

[hexed pecan]

Baking sounds interesting too

Similiar to what I did with AI shooting/cover positions

[hexed pecan]

It does have an FMOD integration yeah

[neon plank]

You bake AI stuff? Cool

[hexed pecan]

Yeah my maps are procedural so everything else has to be procedural too heh

Generated at the start of the game/scene load

I have also seen people use some sort of pathfinding, such as A*, for audio occlusion

[neon plank]

Ohh

Interesting

[placid kettle]

unity at home be like:

[hexed pecan]

What engine/framework is that?

[placid kettle]

its my own engine lol
im trying to make myself a private engine that mimics the syntax of unity

[hexed pecan]

Cool, so C++/glfw?

[placid kettle]

yea

funnily enough all i wanted to make in the beginning was Tertis lol

but the project kinda spiralled out of control and now im left with the beginning of a game engine

[slim trail]

someone have any idea why my object don't move ?

i don't freezed position

[hexed pecan]

What is supposed to make it move?

[slim trail]

transform vector changing

and move towards

also doesn't work

[hexed pecan]

First off, you should move it via the rigidbody instead of the transform
