or used enums instead of const strings

#

what has the data got to do with it, if he had used those strings as file names he would have had the exact same problem

west lotus
#

That is true, then I would be asking him why are they different files

#

The point is that storing json in pp is bad

knotty sun
#

storing anything in pp is far from optimal

west lotus
#

Agreed

I actually prefer ini

I'm struggling to find a way to contain my camera within the game bounds.
If the player gets really high up in a corner of a room or crouches under something small the camera will clip!

Any thoughts on how I can overcome this?

I've tried a collider to no avail!

Fixed the issue!

white crater
#

maybe have a CanStand bool which raycasts above your head to see if the player can stand up again

#

and if the player cant they stay crouched

#

hoiw are speed lines like this (where instead of following where the camera is looking its angled n the direction of momentum)

hey guys, rn i have a script to destroy cubes when hit by tag "weapon", however i want them to destroy after a 5 second delay. i have destroy(gameObject, 5f) in my script on the collisionenter method but the delay does not work

knotty sun
tawny elkBOT
marble venture
knotty sun
#

right so how do you know that the Destroy is even being called? I see no attempt at debugging in your code

marble venture
#

well then i guess i dont.

#

upon adding the debug, it is being called however

knotty sun
#

where did you add the debug?

marble venture
#

under the destroy(gameobject, 10f) line

knotty sun
#

ok, so that would suggest that one of the other Destroy calls is taking precedence

Hey, how does onCollisionEnter work with Character Controllers? I tried it and it didnt detect the collision, so now i tried OnControllerColliderHit which too, had no result. Do you guys know what im doing wrong?

image.png image.png
heady iris
#

You'll receive that message on both sides of the collision

#

OnCharacterColliderHit fires when a character collider tries to move into a non-trigger collider

#

That only fires on the character controller side.

heady iris
#

If you try to move into a solid object, your motion stops short of the object

#

and so you never get a collider overlap

#

I would suggest using a trigger collider here

#

you will want to put a kinematic rigidbody on the item

#

Without a rigidbody, the trigger still works...eventually. It's a bit flaky

unreal sonnet
#

Would you say using character Controller is worth it at all in that case?

#

It just feels so weirdly thought out

heady iris
#

it's very useful for first person movement, yes

#

it's just important to understand that it's not a physics object like a rigidbody is

#

it's just scooting around every time you ask it to Move()

unreal sonnet
#

I see i see

#

Because i am trying to make a physics based game

heady iris
#

If you want the player to be affected by physics, then you'll probably want to use a rigidbody.

unreal sonnet
#

ouch

#

welp, time to rewrite all the code

#

if i load a scene additivley, is there a way to also take that scenes environment and fog settings and applying them to the main scene ?

heady iris
#

You'd need to get the environment settings for a non-active scene. I can't find an example of how to do that.

rocky jackal
#

me neither, a scene aperently doesnt have a refrence for its render settings thats why im asking for help

round violet
#

it might be a weird question but, can I add/remove attributes at runtime ?

#

like an "#if" but for using or not code at runtime

heady iris
#

an "attribute" is something like [SerializeField]

round violet
#

yes

heady iris
#

These are compiled into your program.

#

what are you actually trying to accomplish here?

round violet
#

i found the solution
just for explaining why i asked this question : i was using a cool plugin that helps me adding custom stuff to the inspector, there was a sort of "alert box", that i wanted to show only if i meet some conditions.

but i just remembered that the same plugin gives a option to show/hide its custom attributes using a function

Hey so I been reading and doing some of the c# on a website but I want to know what should i be learning so I'm now wasting my time. I'm right now learn about classes but it's hard to wrap my head around the more complicate ways to have classes from polymorphism, abstraction, and interfaces

Are you looking at the official documentation?

no on a w3school website

hey guys, I've looked up a few methods on YouTube for saving data when creating a new save, but they didn't quite meet my needs.
I have a question:

when saving data in JSON text format, how does the Unity hierarchy work? Is it saved? If not, is there any way to save it?

I've got some interesting implementation such as moving my gameobject instantiation onto my SOs so I only need to serialize the data object

#

basically if it's unique custom data then you serialize it raw via structs, otherwise you should have an ID to them so you can just look it up in your load manager

i have a class which stores a bunch of stats in the form of a Stat class, but i'm running into a problem in the form of the save getting bigger and bigger the more i add
i don't save the values if a stat doesn't have any values, but it still saves the name

i use json, here's an example of a stat that's saved even though it's blank

          "statModifiers": []
        },```
what would be a good way to get around this?
heady iris

If you're using Json.NET, you can configure it to not write empty collections

i use Newtonsoft with the following settings ```JsonSerializerSettings settings = new JsonSerializerSettings();
settings.NullValueHandling = NullValueHandling.Ignore;
settings.DefaultValueHandling = DefaultValueHandling.Ignore;

I've made an animation for the laser but the size of the sprite changes each frame so I'm trying to adjust the collider size per frame, but it's not working too well.

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

public class AdjustColliderSize : MonoBehaviour
{
    public SpriteRenderer spriteRenderer;
    public BoxCollider2D laserCollider;
    public Bounds oldSpriteBounds;
    public Sprite oldSprite;
    public Vector2 originalPosition;
    // Start is called before the first frame update
    void Start()
    {
        oldSprite = spriteRenderer.sprite;
        oldSpriteBounds = spriteRenderer.sprite.bounds;
        originalPosition = laserCollider.gameObject.transform.localPosition;
    }

    // Update is called once per frame
    void Update()
    {
        //Checks for the new frame
        Bounds newSpriteBounds = spriteRenderer.sprite.bounds;
        Sprite newSprite = spriteRenderer.sprite;
        //Determines if the sprite has changed and changes the collider size based on the new sprite
        if (newSprite != oldSprite)
        {
            laserCollider.size = new Vector2(newSpriteBounds.size.x, newSpriteBounds.size.y);
        }
        //I hoped to move the sprite back to its original position to account for the size change DOESNT WORK
        laserCollider.transform.localPosition = new Vector2(originalPosition.x, (originalPosition.y - newSpriteBounds.size.y));        
        
        //Sets the sprite in this frame as the old Sprite
        oldSprite = newSprite;
        oldSpriteBounds = newSpriteBounds;
    }
}

making geometry dash prototype. I'm using the component Constant Force 2D. force X = 4 the rest is set to 0. I have a VelocityClamp script on it which works. The problem I am having is in my playerController script if got a private void OnJump Method() { rigidbodyPlayer.AddForce(jumpHeight * speed); } so i got the 2d square to jump but it resets its velocity. Should I be using somthing other than AddForce? I'm sure there is a way but how would I store the current velocity of x and just add force to y.

Seems like just an animation issue. It's stuck in one state (jumping/falling?) because it's not detecting the ground

you arent supposed to be able to move

its doing it on its own

You aren't supposed to move in what cases?

Essential info missing here

after being knocked back theres something like 3 seconds of waiting before you can move

#

probably something with hitting the spike search after the funcition or in it

#

There might just be remnant velocity from the last rigidbody.velocity change.

You need to debug if you're still entering the if statement on PlayerMovement, line 48 after hitting a spike

#

The core C# side of Unity is open-source, as well as some packages, so yes. Everything that uses the C++ side is not, you need to pay a license for that

#

But consider using the easiest way of inheriting and overriding the class you need, to provide your own behavior

#

It may not be possible (compiler errors, technical restrictions), but worth a try

#

Like class MyCustomInputField : InputField then see if there are methods you can override

atomic cliff
#

ok I'll try

heady iris
#

A lot of the UI classes are very extensible

brittle oyster
#

Bump

heady iris
#

this sounds problematic because it's a variable amount of data

brittle oyster
#

The length of the array will be identical for each chunk

#

The full stride of the entire buffer won't be variable

heady iris
#

ah, okay

#

I'm not experienced enough to know how to implement that, alas. It sounds like something you'd use a constant buffer for.

brittle oyster
#

Gotcha, if anyone know an answer to this, it'd be a big help

hoary mason
#

would this cause a behavior like Input.GetKey or Input.GetKeyDown

vagrant blade
#

GetKeyDown

hoary mason
#

aah ok thanks!

#

yeah that was what I was looking for

#

though if it was for GetKey I'm guessing it'd be Value?

heady iris
#

It depends on how you're actually receiving input

heady iris
#

If you want GetKey-ish behavior, you will want to get a reference to the input action and then constantly check if IsPressed() returns true

#

If you want GetKeyDown behavior, there are many ways to get a function called when the action fires (PlayerInput component, subscribing to the performed event on the input action, checking if WasPressedThisFrame() is true on the input action...)

#

The Button action type is mostly there to let you have different "press" and "release" thresholds

#

So you can have a button with a controller trigger binding

#

That button can go to "pressed" when you pull the trigger all the way

#

but then only "release" when you release the trigger almost all the way

#

It also means that performed only fires once, when the trigger pull exceeds the threshold

#

a Value type action fires the performed event every time the value changes, if I recall correctly

#

i need to go catch a hisuian typhlosion (very important) so I'll be out for a bit

#

UnityWebRequest i think

#

I think that if you setup a server with an asset on it you could download it to unity if that's what you want you could Ask chatgpt for the details and Google the rest

near wagon
#

hey how can i fix this, if the player takes damage then stays on the spike it doesnt damage him again

image.png
vagrant blade
near wagon
#

like invincibility

#

so it doesnt work

vagrant blade
#

Sounds like a design timing issue.

#

If you want the invincibility to be longer, then just keep bouncing them every time they hit the spikes, even when invincible?

near wagon
#

ohh

#

good idea

#

thanks

atomic cliff
#

You can probably setup a free server on github or something else you could pay like 10$ for server on cloud

How do you make it so that the unity console always scroll to the very bottom, the latest message, as they are logged? Where's the checkbox for that?

}```
I'm trying to figure out how to keep this immutable and unfortunately I don't believe NaughtyAttributes is enough here.  Are there any interfaces which I can utilize here or am I looking at reflection if not a custom editor script?
quartz folio
latent latch
#

Another idea is using this method at nested level:

public void SetMovementType(MovementType movementType)
 {
  #if UNITY_EDITOR
  MovementType = movementType;
  #else
  Debug.LogWarning("SetMovementType called at runtime. This method should only be used in the Editor.");
  #endif
}```
But does that seem a little crusty?
latent latch
#

I guess a few questions on this would be what's the idea around using interfaces when a lot of the implementations are generally the same? In this example I'd just be copy pasting a lot of the code which feels wrong, but the idea of having multiple classes would be ideal too over checking an enum for its implementation.

  1. I have a pop-up window.
  2. the Pop-up window has two panels Step1 and Step2.

it renders ok in game, but editing in editor is clunky due to panels being side by side, is there any solution to it?

I have a stencil shader to apply to my sprite renderer (enemy) and another one for my mesh renderer (fov cone)

I want to make it so the enemy's sprite is only visible in the cone shader stencil, but the sprite doesnt display no matter what.

first image is the stencil mask first pass second is the shader attached to the sprite renderer's material. Third image is what happens in game if I turn the first stencil's ZWrite on, yellow boxes are the enemies. You can see the FOV mesh is correctly blocking part of the enemy but the enemy sprite is no matter what, unblocked by fov cone or not, not displaying the sprite.

I think my question is "how do I make a stencil shader that displays the object's sprite if Comp is true"

# cosmic rain Wdym by "get the canvas to life"?

Sorry for my English, I'm Spanish, I have an instance of my player at startup, and I need to get the player's life to be able to put it on the canvas. I'm using GameObject.Find("").GetComponentInChildren<>() but it doesn't work for me

latent latch
#

dont find it

#

make a variable on your player to take in HealthHud if you need it on them

#

and just stick the UI on the scene

cosmic rain
heavy totem
cosmic rain
#

Or it's not active. Check the docs for the GameObject.Find method.

#

Actually nevermind that. It doesn't care about object being active it seems.

#

Assuming the error points to that exact line, the object probably doesn't exist when it's called

heavy totem
#

If it exists when I click start everything is still there, but I don't know why it doesn't get the reference

cosmic rain
heavy totem
#

The error is that it does not get the reference when the player is instantiated is a prefab

cosmic rain
# heavy totem

I don't see the object with that name on your screenshot.

heavy totem
cosmic rain
heavy totem
#

yes

cosmic rain
#

I see that you're doing networking which might be making things even more complicated. You probably want to inject the references from your player instance to anything that might need a reference to it, instead of using find.

cosmic rain
# heavy totem yes

Then it probably happens within one frame, but your Find call is executed before the object is spawned.

heavy totem
#

Ok, I'm going to try to see if it works from OnStartServer.

cosmic rain
#

Honestly, sounds like it's too early for networking if you can't debug that issue on your own.🤷‍♂️

untold siren
#

having an odd issue with coroutines...

coroutine is defined in my base weapon script, baseweapon.cs:

        public IEnumerator WeaponCooldown()
        {
            weaponAction = WeaponState.Firing;
            var cooldown = weaponFireRate / 10;
            yield return new WaitForSeconds(cooldown);
            weaponAction = WeaponState.Idle;
        }

I then have sub-scripts that inherit from this base class - however if the player has one of these inherited classes active as their current weapon, the coroutines don't seem to be waitingforseconds / they appear to be stuck in an infinite state, however I can break this state even though the checks to not do this already exist in the base class..

for example:
in baseweapon.cs I have defined my firing here:

        public virtual void Fire()
        {
            if (weaponAction != WeaponState.Idle) return;
            if (currentPrimaryAmmo <= 0)
            {
                needsToReload = true;
                return;
            }
            currentPrimaryAmmo--;
        }

and overriding this in my script, pistol.cs:

    public class Pistol : BaseWeapon
    {
        public override void Fire()
        {
            if (weaponAction != WeaponState.Idle) return;
            Debug.Log("pistol firing");
            base.Fire();
        }
    }

however, it always bypasses the check to see what state the weapon is currently in

is there something obvious I'm missing here or?

#

I'm assuming its either where I'm calling the coroutine from

#

or just some weird thing I'm missing

#

coroutines are being called from PlayerShooting.cs, attatched to the player:

        public void Reload()
        {
            StartCoroutine(currentWeapon.Reload());
        }

        public void Fire()
        {
            if (currentWeapon == null) return;
            currentWeapon.Fire();
            StartCoroutine(currentWeapon.WeaponCooldown());
        }
latent latch
#

why do you have two fire methods here

untold siren
#

each current weapon will have its own firing override, i.e. a pistol firing vs a shotgun firing will have their own definitions on the subclasses

the one in playershooting.cs is the function that gets called when mouse1 is clicked

#

via input system

latent latch
#

ah, ok I see it

untold siren
#

yeah salute

latent latch
#

but your player has no cooldown on firing the weapon

#

rather, you start a coroutine everytime you fire

#

there's no checking if you're in a cooldown or maybe im sleepin

untold siren
# 
            StartCoroutine(currentWeapon.WeaponCooldown());

calling this from the player, I'm assuming it'd be best to call it from the actual weapon script?

latent latch
#

uh, it's up to your design, but usually you have the attack speed/cooldown on the weapon itself so the player isnt stuck cooldown down when swapping weapons

untold siren
#

gotcha, that makes sense to me

#

I'llsee if its that causing the issue

latent latch
#

but as I said before, you start a coroutine everytime you fire it seems

#

you should be checking if you're in cooldown on the player itself in this scenario before calling weapon firing

untold siren
#

that's done by this check here:

            if (weaponAction != WeaponState.Idle) return;

unless I'm mixing it up - the weapon states are:

  • reloading
  • idle
  • firing
  • noammo
#

so it would require the weapon state to be idle for it to be able to fire in the first place

latent latch
#

if you do this:
currentWeapon.Fire();
then even if you return from this:
if (weaponAction != WeaponState.Idle) return;
you're still executing this:
StartCoroutine(currentWeapon.WeaponCooldown());

untold siren
#

gotcha

#

so if I change the fire function on the player to just:

        public void Fire()
        {
            if (currentWeapon == null) return;
            currentWeapon.Fire();
        }

and then proceed to update the fire function on baseweapon.cs to:

        public virtual void Fire()
        {
            if (weaponAction != WeaponState.Idle) return;
            if (currentPrimaryAmmo <= 0)
            {
                needsToReload = true;
                return;
            }
            currentPrimaryAmmo--;
            StartCoroutine(WeaponCooldown());
        }

I'm assuming that would circumvent the issue?

latent latch
# 
if(currentWeapon.Fire())
{
  StartCoroutine(currentWeapon.WeaponCooldown());
}```
untold siren
#

looks like my method also works

#

hell yeah

#

thank you for the input!

What shader are you using for it?
Also, it's not a coding question.

how can i make it not change the scale of the bullethole prefab when its parented to an object?

// Graphics
    if (Physics.Raycast(fpsCam.transform.position, direction, out rayHit, range))
    {
        // Executes if hits a collider
        Rigidbody rayHitRigidbody = rayHit.collider.GetComponent<Rigidbody>();
        if (rayHitRigidbody != null)
        {
            Instantiate(bulletHoleGraphic, rayHit.point + rayHit.normal * 0.01f, Quaternion.LookRotation(rayHit.normal, Vector3.up) * Quaternion.Euler(90, 0, 0), rayHit.transform);
        }
        else
        {
            Instantiate(bulletHoleGraphic, rayHit.point + rayHit.normal * 0.01f, Quaternion.LookRotation(rayHit.normal, Vector3.up) * Quaternion.Euler(90, 0, 0));
        }

ok ty

such a simple fix and its fixed an issue that i didnt want to solve :3 thank you tons!!!

Ok so i created an empty monobehaviour script, and didnt attach it to anything, and it got included in assembly(in the build) regardless
Is there an option for this? I thought it shouldnt be included if its not in scene

no (im testing on a new project too, same result)

#

Unity strips most unused Assets during the build, so you don’t gain anything by manually removing Assets from the Project. The only Assets that are not removed are scripts (which are generally very small anyway) and Assets in the Resources folder (because Unity can’t determine which of these are needed and which are not).
also found this

#

Yes, "assets" as used here in the docs unfortunately only refers to non-script assets. For scripts, we have no way of tracking dependencies like for other assets. Some platforms have dead code stripping so unused code is removed but the webplayer and standalones don't do that.

One reason for this is that it is a non-trivial problem. If you are using reflection, for example, it is often quite impossible to tell which scripts you are actually using and which you are not.

And in a sense, since the compiled DLLs will actually include all scripts, the scripts are not actually unused.

spring flame
#

How to model this in code:

  • I have a "root" game object with a script that generates some asset (in my case shader and updates material, but that's irrelevant for now)
  • children of this "root" can be added, removed and their script values modified — the root should react in that case. (In the edit mode, it should update generated shader code, in the runtime it should only update uniforms)

Can someone give me an example code how to do that? I was thinking using OnEnable to find ancestor root and attach to the roots events, and a bunch of events in the root like childChanged which in turn root component listens on and reacts accordingly (update uniforms / regenerate shader if needed)

#

others seem to report similar issues. anyway ill try with #if UNITY_SERVER but would be nice if didnt have to

#

using platform define or however its called worked for me

knotty sun
quartz folio
#

Whatever that's quoting from is probably just using the term script to refer to a MonoBehaviour or ScriptableObject

#

Also, seems nonsense when it talks about reflection. That's not guarded against when stripping, it's part of the reason reflection is a poor choice at times, because you have to mark the things you care about as preserved

knotty sun
#

I wonder if there is a difference between Mono backend and IL2CPP because IL2CPP stripping seems to be much more aggressive

quartz folio
#

There definitely is

heady iris
#

Yeah. IL2CPP won't even permit you to disable stripping entirely

#

Although I wonder if "minimal" stripping just winds up being whatever the AOT compiler decides to remove

knotty sun
#

It plays merry bloody hell with generic types, I can tell you that

How can I implement camera boundary detection when my camera is tilted 45 degrees on the x-axis? I have tried a couple of methods, but they don’t seem to work. The closest thing I can get is using GeometryUtility.TestPlanesAABB to detect whether or not the player is inside the camera view, but I’m not able to go further.

Hi does anyone use Guids to id things in their game and use a helper class to serialize and handle empty value?

heady iris
#

I use GUIDs to identify some categories of objects.

#

They're all assets, so I just copy unity's GUID over in OnValidate

#

(not a huge fan of doing all that work every single time validation happens. I might just write an editor tool to copy them over on command instead)

placid summit
#

ok this is for like saved data, not assets

#

but I see some other people have wrapped system guid now. wrapped for serialization

heady iris
#

I reference these assets in saved data

#

(by serializing the GUID as a hex string)

#

maybe I should switch to writing base64..

placid summit
#

what I see people doing is just using a string (System.Guid) guid.ToString() on serialize/deserialize via a wrapper class. In order to use System guid and the fast comparison of that compared to just using strings

heady iris
#

I use a custom Guid class that Unity can serialize.

#

(since System.Guid is not Unity-serializable, for some reason)

placid summit
heady iris
placid summit
#

yeah that seems to save the guid as four values rather than just convert guid to 1 string and save that

obsidian zinc
#

i am sorry to interrupt your conversation... what's the matter? i can help you?

heady iris
#

I still serialize it as a string when it gets put into a JSON file

placid summit
#

ok

#

yes I will ultimately be using JSON so may skip Unity's serialize pain

heady iris
#

I still needed it to be unity-serializable so that I could actually store the value in the asset

wary coyote
#

as a developer how would you make sure that anyone who edits one of these methods also makes the same edit in the other method?
The problem I'm trying to solve is that while editing a material or material property block produce functionally the same result, they are technically completely different so I haven't been able to write one single unified method

image.png
placid summit
#

DRY - don't repeat yourself. Is One call simpler than the other? Can one call just call the other?

wary coyote
placid summit
#

yes I see, not sure of why it must be so, but you could make 1 call that takes a material or a property block and applys to 1 OR the other. Then at least all Set calls are in one place/function

heady iris
#

You could make an "adapter" class that accepts either a property block or a material

#

and presents a consistent interface

#

then you can hide the ugly repetition in there

#

I'm doing something like this for my game's "choice" settings. I have many different kinds of choices -- a list of literal Choice assets for my settings system, a list of entities to spawn, a list of maps to load

#

They all get wrapped up in an IChoiceItem interface that has methods for switching to the next/previous choice, describing the current choice, etc.

#

...IChoiceItem is a really bad name for something that's multiple items, on second thought

#

i should fix that

placid summit
#

yes Fen's is the pro way! But for speed just have the 2 current calls call 1 function which accepts either material or property block and then do each set call on whichever is not null!!

wary coyote
#

That makes sense, Ill make a higher level routing class with nulled parameters UnityChanThink

how to stop rigid body player from bouncing when moving on slopes?

heady iris
wary coyote
#

Yeah that was my issue, they aren't technically the same thing and are not interchangable, even if the result more or less is

heady iris
#

You could subclass both Material and MaterialPropertyBlock and implement an interface with the SetColor/etc. methods in it, then accept an argument of that interface type. But that wouldn't really make any sense, since you'd have to use MyMaterial and MyMaterialPropertyBlock

Hey. I am having a spaceship, which shoots bullets with rb.Addforce(). I want the velocity of the spaceship to be taken into account when shooting the bullet. How do I do that?

Code:

fire.transform.parent = null;

fire.GetComponent<Rigidbody2D>().AddForce(this.transform.up * force);```
fleet furnace
humble pumice
#

Didn't work.

#

The bullets didn't move at all then

rigid island
heady iris
#

Yeah.

#

The default force mode -- ForceMode.Force -- is for continuously applying a force.

#

ForceMode.Impulse is for an instant "kick"

#

One second of ForceMode.Force calls is equal to a single ForceMode.Impulse call

humble pumice
#

Ah, I completely forgot this was a thing!

#

Thanks!

heady iris
#

I forget if the Force and Acceleration modes misbehave when used in Update

hard viper
#

at least in 2D, ForceMode.Impulse directly adds deltaT * force / mass directly to the velocity. Immediately in that line

heady iris
#

3D physics delays it until the physics update

#

didn't know about that distinction!

hard viper
#

2D does not delay. It is instant, one line to the next. And no, that is not better.

#

It SHOULD get delayed so you can read it in different scripts, and see what velocity came in as velocity vs some impulse-added force in the middle.

#

assuming 3D has a way to read the total impulse force, that is the better way imo

heady iris
#

I don't think you can ask for the "pending" force

#

but yeah, it's generally more annoying when changes apply immediately

hard viper
heady iris
#

copy the game's memory to a file, run until the next physics update, measure the velocity, and restore the game's memory. ezpz

hard viper
#

in my custom physics engine, key things you can read include also the next MovePosition, if applicable, for a kinematic RB

#

my PhysicsMover API just logs shit when it gets external requests

#

then it combines everything right before physics solve

#

it is extremely annoying to not be able to read MovePosition, or if there is a current MovePosition at all

#

it’s okay though. I assume all of Unity’s new staff will fix it. And by new, I mean the ghosts taking over the workstations of all the laid off workers

Howdy folks! I'm watching through a tutorial on using Lobby for multiplayer, and the tutorial creator keeps surrounding everything relating to connecting in joining in try/catch like this:

    // Stuff relating to creating or joining lobbies in here
} catch (LobbyServiceException e)
{
    Debug.Log(e);
}```
I'm not entirely sure what this is meant to do, as all it does is log the error. Also, is this something I should just keep when testing and remove after, or I leave this in after creating my lobby system?

Hey everyone, I have a bit of a head scratcher. I have a function that updates a little minimap with a color sampled from the terrain as the player crosses it. It works just fine aside from the texture I'm creating having this weird artifacting. The black cross in the middle should not be there, the other two black dots should be. I tried changing the filter mode but no go. Anyone have any ideas? Below is what I'm seeing an the associated code. All outputs are working correctly as far as I can see. It is trying to assign the correct pixel the correct color.

        mapTexture = new Texture2D(rs.wc.worldWidth, rs.wc.worldHeight);
        // mapTexture.filterMode = FilterMode.Point;
        for(var i = 0; i < mapTexture.height; i++){
            for(var j = 0; j < mapTexture.width; j++){
                mapTexture.SetPixel(i,j, Color.black);
            }
        }

       ApplyTextureChange();

    }```
```    public void UpdateMap(Vector2 coords, Color color){
        int convertedX = (int)coords.x;
        int convertedY = (int)coords.y;

        if(coords.x <= 0){
            convertedX += rs.wc.worldWidth/2;
        } else {
            convertedX -= rs.wc.worldWidth/2;
        }

        if(coords.y <= 0){
            convertedY += rs.wc.worldHeight/2;
        } else {
            convertedY -= rs.wc.worldHeight/2;
        }

        Debug.Log($"{convertedX} - {convertedY}");

        mapTexture.SetPixel(convertedX, convertedY, color);
        ApplyTextureChange();
        
    }```
```    void ApplyTextureChange(){
        mat.mainTexture = mapTexture;
        mapTexture.Apply();
        gameObject.SetActive(false);
        gameObject.SetActive(true);
    }```

I understand what try catch does, I'm just confused on what its purpose is in this situation where it only logs the error.

knotty sun
#

it stops your program blowing up

tiny delta
#

Right, but theoretically if things are functioning I shouldn't be getting any errors in my scripts, no? And if it does blow up then the error is still logged and so I go to the error

knotty sun
#

this is network code, it will always go wrong so you have to deal with it

tiny delta

Gotcha, so should I keep it in my finished product then just to be sure so that if a connection goes wrong or somebody's wifi goes down or anything that the entire game doesn't go up in flames?

Hey, I'm trying to figure out how to get a "audio to fire ONCE when passing over the threshold, then RESET if not in threshold". Problem is, sometimes the range is a mixture of positive and negative. The else if seems to work sometimes, but because it randomizes into the negative range or positive range, a >/< doesn't always work. Any ideas on how to capture the range, then do a != against it?

 // Pick can only rotate when not rotating keyhole (keypress)
 if (canMoveLockPick)
 {
     Vector3 dir = Input.mousePosition - cam.WorldToScreenPoint(lockpickTransform.position);

     eulerAngle = Vector3.Angle(dir, Vector3.up);

     Vector3 cross = Vector3.Cross(Vector3.up, dir);
     if (cross.z < 0)
         eulerAngle = -eulerAngle;

     eulerAngle = Mathf.Clamp(eulerAngle, -maxAngle, maxAngle);

     Quaternion rotateTo = Quaternion.AngleAxis(eulerAngle, Vector3.forward);
     lockpickTransform.rotation = rotateTo;

     // If you pass over pin, then play audio
     if (eulerAngle < unlockRange.y && eulerAngle > unlockRange.x)
     {
         if (!firePinAudio)
         {
             firePinAudio = true;

             // pin audio is quiet
             audioSource.volume = tumblerVolume;
             audioSource.PlayOneShot(inRangeAudio);
         }
     }

     // If not within range, then reset audio so it can be fired again! 
     else if (eulerAngle > unlockRange.y && eulerAngle < unlockRange.x)
     {
         firePinAudio = false;
     }
 }
image.png image.png image.png
#

Like for example range is 30 - 90; then its -25 to 50, or -25 and -13. I'm not sure how to get the min max threshold range as a variable then invert it as the "reset area"

heady iris
#

You can use Mathf.DeltaAngle to ask how far apart two angles are (measured in degrees)

#

If you specify the unlock range as an angle and an angular width, you can then just check if the angle delta is less than the width

#

this will let you add an unlock angle that straddles the 180 -> -180 transition

hey guys, I am still stucked on my Coyote Time, when I jump the first time, the hasJumped is not true, it's true after the second jump
https://paste.ofcode.org/38Gj9dNhwfva7gcFjwmPyQX

Here's one for y'all: When the player is holding an item, I project a ghost (Instantiated copy with new material) of the item to show where they will place it when they use the Drop action. What would be the cleanest way to have that ghost copy the state of the original object? Say it was a small lockbox and the player opened it - I would want the ghost to also appear opened.

I could brute force this by passing a reference to the original and when I run a method, I check for a ghost and run it on there as well, but I'm not sure how to best make it more systematic so I can easy apply it to all possible types of pickups with different and potentially multiple manipulations possible (an apple with X number of bites out of it / a puzzle box with 3 specific panels opened / etc.)

Been scratching my chin over how best to approach this.

vagrant blade
#

I feel like most games wouldn't go to this level of detail, and unless it's mandatory for gameplay, the player won't even notice that it's the "default state" of the object they're holding.

crystal star
#

Oh, I agree. Definitely not neccessary. I'm just a glutton for dumb polish and was curious.

heady iris
#

I'd expect it to be similar to however you restore the state after you place the object.

vagrant blade
#

But if it's mandatory, the only way would either be to brute force it as you said, or somehow create a state system for all objects to have? And you drag/drop variations of models to represent a "used" state, "damaged" state, "eaten" state (and leave them blank for things that don't make sense), which in turn would be a list of substates so you can have multiple versions (ie, multiple bites of an apple) with some property value representing which index you're at. Then you iterate and match.

heady iris
#

Especially now that you have working 'coyote time'

crystal star
heady iris
#

ah, I see

limber wharf
vagrant blade
#

Actually, you may get away with instantiating the literal version that the player has in their hand rather than a prefab. Depends on how you've modified the object at runtime to be in its current state.

You could also make IsGrounded() return false briefly as long as your vertical velocity is positive

Hey all, any idea as to why my character suddendly stops moving every now and then? The velocity keeps going up and back to 0 when this happens.

rigid island
#

also should move using FixedUpdate

lavish frigate
#

rigid island
#

no they already move with fixed time step

lavish frigate
#

damn okay have been doing that wrong all these years

#

still having my issue

#

movement code is now this

limber wharf
#

hey @heady iris sorry for pinging, just wanted to let you know that I solved the issue by changing the (groundCheck != null) to (rb.velocity.y == 0)

rigid island
#

also why Sign

lavish frigate
#

okay so

#

i can move around, but every now and then, even though input is registered, it stays at vel 0

#

in the video i hover around the values in the editor even though the player is not moving

Ohh

lavish frigate
#

i had this issue also before clamping velocity

rigid island
#

how do you get HorizontalInput

lavish frigate
#

Throught the new inputactions system

hard viper
#

that is dangerous

hard viper
# lavish frigate

you are subscribing an anonymous function to a delegate that exists for the entirety of your game.

#

meaning you cannot -= it

lavish frigate
#

what is the anonymous function here?

#

not really well read up on delegates

rigid island
#

ctx =>

hard viper
#

ctx => Horizont….

#

do you know about pointers?

lavish frigate
#

kind of in C haha but not in C#

hard viper
#

a delegate is like a pointer to functions

fervent furnace
#

anonymous function is function with no name
ask yourself what the name of ctx=>some codes is

heady iris
#

the problem is that two identical-looking anonymous functions are still going to be two unrelated objects

#

so you can't unsubscribe from that event later

#

[...].canceled -= ctx => HorizontalInput = 0f; will do nothing

lavish frigate
#

So if that is bad practice, why is the new input system praised?

heady iris
#

well, don't do the wrong thing

#

this has nothing to do with the new input system in particular

hard viper
#

a delegate is kind like a collection (list) of functions to call when invoked. But it is not actuallt a collection. You can’t .Count, access by index, and there isn’t actually an order

hard viper
lavish frigate
#

So i would use this for a jump for example?

heady iris
# 
    void OnEnable()
    {
        upAction.action.Enable();
        upAction.action.performed += TryPop;
    }

    void OnDisable()
    {
        upAction.action.performed -= TryPop;
    }

a little example of subscribing and unsubscribing

hard viper
#

old input system requires any anything that checks input to basically check in Update() every single frame, every possible input. And if that method is not in a monobehaviour, you can’t just do it.

heady iris
#

when this component is disabled, it removes its TryPop method from the performed delegate

#

so it's not called at all

lavish frigate
#

ahh okay

hard viper
heady iris
#

This is particularly important if you've turned off Domain Reload and are using things like InputActionReference

#

otherwise you'll have stale delegates left over from the last play session

hard viper
#

but EventSystem also can interface with playerInput components to rewire it anyway

lavish frigate
#

i see

#

ill have to look a tutorial as well then i guess

#

dont wanna start off wrong

#

thanksd guys!

hard viper
#

InputSystem also makes it easy to rebind, especially for different control schemes or platforms

heady iris
#

There are lots of ways to get input with the new system, which can be a little overwhelming to try and learn all at once

hard viper
#

the two main patterns are:

  1. .ReadValue<>() to get the current value of an input. This is for something like reading the Vector2 for a control stick, or if a button is down vs up.
  2. Make a method that takes as an argument InputAction.CallbackContext, and subscribe/unsubscribe this method to the delegates for your player input. So whenever invoked, that method gets called.
heady iris
#

I use InputActionReference for most of my code. So things can look like this

# 
moveActionReference.action.ReadValue<Vector2>();

Can Radio Direction Finding be replicated in Unity?

I was wondering if radio waves can be replicated or simulated in Unity somehow.

I want to make a simulator simulating Radio Direction Finding and was wondering if Unity can replicate radio signals and translate it to UI element based on strength from the 4 antennas

lean sail
#

Not sure what translate it to UI elements means though

somber nacelle
#

probably an overlapcircle and a raycast. overlap to check if it is in range, then raycast to attenuate based on distance, penetration through other objects

tidal pumice
lean sail
#

You would just use the direction from the radio source and compare it to like up left down right to see what to light up

tidal pumice
#

Ok, I'll start reading up.
Thanks for the insight

heady iris
#

If you want more complex radio behavior, like lobes on directional radio sources, that should still be reasonably easy to implement

#

I am trying to draw all edges using Gizmos, but the count is incorrect.

#

Does the triangle array not match per 3 index positions?

#

If I modify the triangle loop to be positive numbers it works for cubes, but still not on planes:

image.png image.png
clever lagoon
leaden ice
granite crown
#

Yeah, I understand its pretty bad, was going to get it working and then improve, it shouldn't be constantly drawing all of these

knotty sun
#

and all those float equality checks, a recipe for disaster

clever lagoon
#

for (int i = 2; i < mf.triangles.Length; i += 3) why start at 2?

leaden ice
#

one big hint:
Every time you do mf.vertices or mf.triangles it creates an entirely new copy of the entire vertex or triangle array from the mesh.

clever lagoon
#

starting at 2. (not a multiple of 3) is gonna give you the wrong points for a given triangle

granite crown
#

When creating the edges I used -1 and -2, but if you switch it, it works better.

for (int i = 0; i < mf.triangles.Length; i += 3)
clever lagoon
granite crown
#

index is 2 and the array is zero based, so 0,1,2 makes 2 the 3rd.

#

@leaden ice is that true even if I use

mf = GetComponent<MeshFilter>().sharedMesh;
#

the shared mesh?

leaden ice
#

it doesn't matter which mesh it is

clever lagoon
granite crown
#

@clever lagoon Yeah so the logic was poorly made in the first edge and second edge:

Edges newEdge = new(mf.vertices[mf.triangles[i]], mf.vertices[mf.triangles[i - 1]]);

I did switch it to not use negatives and start at 0. This works correctly for cubes, but not planes

clever lagoon
#

ah! your using i-1 and i-2 not i+1 and i+2.. ok starting at 2 works or tat I guess.. jus a bit confuing

granite crown
#

I am unsure why all edges are not being drawn in the plane

#

yeah I agree glurth haha, I swapped it back to normal.

leaden ice
#

Wouldn't you just do this?

int[] triangles = mesh.triangles;
Vector3[] vertices = mesh.vertices;

for (int i = 0; i < triangles.Length; i += 3) {
    Vector3 a = vertices[triangles[i]];
    Vector3 b = vertices[triangles[i + 1]];
    Vector3 c = vertices[triangles[i + 2]];

    Debug.DrawLine(a, b);
    Debug.DrawLine(b, c);
    Debug.DrawLine(c, a);
}```
#

not sure why you need more than this

clever lagoon
#

btw, when you say all edges- do you mean the edges of all the triangle, or the "final" edges of the whole plane itself?

#

for ALL tri's I like Preaetor's answer

granite crown
#

So as I understand it the triangle includes duplicate edgeswhere they match the other tris, I was trying to get rid of duplicates.

leaden ice
#

It's possible depending on the mesh but

#

if you're just trying to get it to work right now why are you worried about culling duplicates?

clever lagoon
#

got it. thats what the Same() function is for (usually we go with "Equals", but thats just a convention.

leaden ice
#

that would only be a performance concern basically

clever lagoon
#

hmm... newEdge , newEdge2 .. what about #3?

granite crown
#

So like on a quad, there are 2 tris, 4 verts and 6 edges. when I run I want it to show only the 5 edges that you can actually see.

leaden ice
#

If you want to cull edges make an Edge class and implement Equals and HashCode (not Same) and just throw them in a hashset then draw them all in a simple for loop

leaden ice
#

How would you even be able to tell

#

Start simple

#

then get complicated

#

this is C++ 😮

latent latch
#

Actually little big let me pastebin it

#

yeeeah well same logic applies

granite crown
#

I am attempting to visualize WFC edges.

clever lagoon
granite crown
#

Ah so you think like instead of going +3, +2 might generate those missing edges?

#

Let me check

clever lagoon
#

no.. I mean you have newEdge and Edge2 but a trinagle has 3

#

[i, i-1], [i-1.i-2] but no [i,i-2[

granite crown
#

The start of the next edge in the array should be the third edge.

#

That change made interesting results haha:

image.png
leaden ice
#

Then you can improve on it if you really want to worry about culling duplicates

clever lagoon
granite crown
#

@leaden ice There is where I started and it works as intended, but it does not have world space only local.

image.png
leaden ice
#

you've overcomplicated this

granite crown
#

@clever lagoon So you are saying the need for the last index per loop needs to attach to the first:

            Edges newEdge3 = new(mf.vertices[mf.triangles[i + 2]], mf.vertices[mf.triangles[i]]);

            foreach (Edges e in edges)
            {
                if (e.Same(newEdge3))
                {
                    found = true;
                }
            }
            if (found == false)
            {
                edges.Add(newEdge3);
            }
leaden ice
granite crown
#

@clever lagoon This is why they pay you the big bucks:

But now it broke the cube.

image.png
leaden ice
#

duplicate edge culling

#

world space

#

etc

#

and much more performant

granite crown
#

Nice, let me take a look at HashSets as I am really new to this, but it looks a lot more straight foward.

leaden ice
#

the hashset is just a collection that doesn't allow duplicates

granite crown
#

Oh really, can the hash itself be referenced?

leaden ice
#

wdym by "the hash itself"?

granite crown
#

I am assuming when an object is added and it creates a hash for the object, then when another is attempted to be added it references the tables hash before allowing it. So I was wondering about how it checks.

leaden ice
#

It uses the Equals and HashCode methods from the Edge struct

granite crown
#

ok, that makes more sense haha

clever lagoon
#

It check by using the .Equals() function. you can override this in your own class to compare member values.

swift falcon
#

Can anyone help, when I play with one player it works perfectly, it spawns one zombie and waits until it's dead. But When I play with two or more , the wave system just skips and doesn't check if the zombies are dead. Also instead of only spawning one zombie, it spawns one zombie per player. I'm not sure if the RPC's are done correctly

hey! been using unity for about 3 weeks now, and I've completed ~12 courses. I'm starting to notice that the courses I'm doing seems to have a lot of variability in the quality of the C# scripts they write, and I'm getting pretty confused about best practices. Is there a wiki or something for this community where I can see a recommended list of courses that teach the correct way to design the gameobjects and scripts? I'm just apprehensive to keep investing 5-10 hours into some more courses that are doing it wrong.

rigid island
spiral geode
#

I was looking at the unity.learn stuff, but that seems to be more geared toward complete beginners learning their first software language

#

i'm more interested in the correct way to go about separation-of-concerns, when to use events vs functions, what to break out into controller/manager, etc.

rigid island
latent latch
#

Yeah I'd start with manager patterns

#

You got your singletons, your observers, servicelocators

spiral geode
#

Model View Presenter (MVP)

interesting, I've seen quite a lot of criticism for MVC/MVCS

#

so this book is the best resource? does the comminity have a wiki/FAQ or something with courses? I'm more of a learn-by-building kinda person

latent latch
#

object pooling is more specific to game design and usually mandatory so understand that

rigid island
spiral geode
#

it's just not very clear when i should look to using events/subscription stuff, vs when to just pass arguments to a function, etc

spiral geode
rigid island
#

yeah I know

rigid island
spiral geode
#

a lot of the udemy-style courses are from people that don't come from a software engineering background, and are pretty much beginners

#

no offense to them

rigid island
#

imagine having ScoreManager call each method in each script when adding a point

#

that would be hell

spiral geode
#

yeah im aware of how the mechanics of these work, but i was hoping to see a complete example showing when to use a specific pattern, and justification for why that design is preferred

latent latch
#

Subscription stuff has been helpful for my items system for when I equip some upgrade. For example I have +% to fire damage, so I'd only want my items listening on modifiers of that specific type instead of iterating through all my items and such.

spiral geode
#

i appreciate all the advice, but I'm specifically looking for resources/courses

rigid island
spiral geode
#

yes i want to find someone with experience explaining the concepts in some formal way (course/book/etc)

#

so i can learn this from them

rigid island
#

there are general practices all over the web , but everything is up to you

rigid island
spiral geode
#

for instance, in web development you could find a course or blog that talks about why you would use an event broker vs http for a microservices architecture. And they explain why its appropriate and under what circumstances to consider each

#

im trying to find something from someone reputable in unity

rigid island
#

then u cannot look into "Unity"

#

its all kiddies

#

you need traditional C#

spiral geode
#

the official unity.learn seems to be more fundamental, like "what is a monobehavior" or "here is what an array is"

#

ahh

latent latch
#

At most learn the singleton pattern and how you'd load and deload from these pattern types, as well as pooling objects and requesting from them

#

if you want to start somewhere

spiral geode
#

yeah this ebook seems to be officially from unity

#

so i'm kinda leaning toward this being the best there is

#

unless for some reason they would release a junk ebook

#

but that seems unlikely

#

am i making a mistake by reading a 2021 LTS book? (new to the whole unity thing)

rigid island
#

Unity and Microsoft, those are literally the sources of everything involved here

spiral geode
#

ahh

rigid island
#

so yeah their stuff is legit lol

spiral geode
#

honestly i wanted to just start with ECS, since that seems like where the engine is going, but they removed all their official courses on DOTS/ECS from the website

#

like you cannot access them

#

not sure why

latent latch
#

ECS does seem fun, I was doing a little bit of it but yeah that's a whole different basket of concepts

rigid island
#

yeah mainly docs for ECS rn not many resources on it

spiral geode
#

well the nice part for beginner is that is makes all your decisions for you (or that's my ignorant undestanding)

#

it looks like it forces you to separate your behaviors in some standard way

latent latch
#

can't say that's beginner but more preventing you from digging yourself a *hole with oop

spiral geode
#

maybe they did all the official courses in pre-1.1 and it isn't compatible 🤷🏻‍♂️

spiral geode
rigid island
spiral geode
rigid island
#

yeah samples are pretty good

spiral geode
#

do you have resources on an appropriate use of events?

#

like a good example of using them correctly

rigid island
spiral geode
#

lol all these videos are watched on my youtube

#

or the top dozen or so

rigid island
#

have you actually started using them at all?

#

cause thats the only way it starts to make sense

spiral geode
#

yeah but it's always in the context of UI

#

like player health/etc

knotty sun
#

Do you not understand the concepts of Events?

spiral geode
#

yes

knotty sun
#

then the context is irrelevant

spiral geode
#

not to me

knotty sun
#

if you understand the concepts why is context relevant?

#

it's like saying I can implement events in JS but I cannot do the same thing in C#, that's just nonesense

spiral geode
#

that's like asking if you understand databases, then telling a developer that it's not necessary to understand what data to persist in a database, and when.

#

knowing how to use a tool is different than knowing when to use it.

knotty sun
#

not at all

spiral geode
#

maybe that's not the way you learn

#

i'm not asking what's best for you.

#

i'm asking a directed question about resources

#

it's fine if you don't think that's something you would personally benefit from

#

everyone is different

knotty sun
#

what I'm trying to get across to you is you seem to be holding yourself back unnecessarily

spiral geode
#

ok well i'm possibly not explaining myself well

#

i'm coming from the software world, but not the game dev world. I've gone through the process of learning from a bunch of courses, and I understand the concepts they are using. However, the people who are teaching these courses are kind of YOLOing the whol design, which isn't something I'm interested in doing. There are people and companies out there that have standards and reasoning behind how to design things properly. I am seeking this information.

somber nacelle
#

don't crosspost

spiral geode
#

@rigid island this unity resources page is nice. It's got all kinds of stuff.

rigid island
#

they got lots pdfs yea

spiral geode
#

i see, all the MVP/MVC stuff is specifically for the 2D UI (in the book)

#

the udemy course I took was trying to kind of jam MVC into everything through some framework in the asset store

#

wtf you can open PDF ebooks in MS Edge and it copilot can read the ebook and you can ask it questions.

#

this is new to me, pretty neat.

#

it understands the book and is responding to questions about it

quartz folio
#

why would you want to do that

spiral geode
quartz folio
#

So can reading

#

If I find an AI has written something I immediately doubt its credibility and go look for other sources. It's a mystery to me why people would go directly to it

spiral geode
#

everyone learns differently.

#

if you know enough to not get fooled by hallucinations, it's great

#

i use it at work and it's improved some of my stuff before

#

sometimes it just lies though

#

@rigid island turns out that guy that wrote the official unity ebook you linked has a course on udemy. Nice! thanks for the link.

quartz folio
#

but if you knew enough to not get fooled by hallucinations you wouldn't need to be asking it anything

spiral geode
#

it's given me refactoring ideas that are seriously impressive on occasion

#

like it understands advanced concepts like monad transformers

latent latch
spiral geode
#

lol hatebin

#

that's new to me

#

can you explain a bit what I'm looking at?

latent latch
#

well, it's an ability and mod system. Mods affect abilities, and to do that usually you need to update every ability when you acquire a new mod.

#

The vanilla way is just iterate through all your abilities which is fine, but when it comes to cases where you should already know that some abilities can't use certain features, then there's no reason to iterate over them.

spiral geode
#

so you have a class nested in a class, that subscribed to this event at the top-level (not in a Start function or anything)?

modHandler.UpdateAbilitiesStatsEvent += UpdateAbilityStats;

latent latch
#

These are just c# classes, so I can use the constructor here for that.

#

otherwise for monos, yeah either Start() or an Init() method you call yourself

spiral geode
#

small typo on :61

latent latch
#

lol, well it was chopped up from a bunch of more code

#

but otherwise looks fine for the basic idea of it all

spiral geode
#

yeah so this is a good example here where i would have a question in the courses I'm taking. Specifically look at line :67

#

in the courses, they will have a class param, declared at the top, and then "abuse" functions that take no arguments. They just pull from the params.

latent latch
#

so, you get a new mod, all items with stats (which is all of them here) will update themselves accordingly, but if the mod is a trigger mod, only those with trigger capabilities will update.

spiral geode
#

whereas I'm much more used to line :67, where it just takes the value as a parameter to the function

#

and they never explain why they chose one or the other

latent latch
#

can probably cut down on the stats idea too and only have some items subscribe to specific stats. Just some ideas

spiral geode
#

i don't understand why you'd ever not do what you're doing here on 67

#

it's way less brittle

latent latch
#

oh yeah always use bitwise enums if possible

spiral geode
#

no i mean just a function with an input

#

as opposed to declaring mods top-level and referencing it on 87

latent latch
#

ah, yeah I see what you mean

spiral geode
#

i just keep seeing that pattern all over the place, even in paid courses

latent latch
#

honestly I havent read crap, I just been playing with ideas

spiral geode
#

that was kind of the root of my original question in here. Nobody in these tutorials or courses seems to explain why they choose to write things the way they do

latent latch
#

there's actually a few problems with c# events too and that they do create garbage

spiral geode
#

for instance, you can now unit test your protected bool CheckAbilityRequirements(AbilityFlags modAbilityFlags) if you choose

heady iris
spiral geode
#

because you can pass it test values

heady iris
#

it's much more common to see that

spiral geode
#

whereas the class-level implementation of this would be a PITA

latent latch
#

I've been advised to try to stick to unity events for heavier subscription systems

#

such as enemy targeting systems

#

where you're constantly subscribing on and off

spiral geode
#

yeah the only downside of events (in my naive understanding) is the same downside as actor-systems in languages like Scala. They are harder to ctrl+click and debug in your IDE

heady iris
#

yes (precisely because they let you decouple things)

spiral geode
#

you cant really follow their use-path without using the find-all

heady iris
spiral geode
#

it's like they are unaware that you can use them

spiral geode
heady iris
spiral geode
#

no i was saying that @latent latch implementation makes more sense to me

#

he has a function that only cares about the AbilityFlags , it literally nows nothing about what else is on mod

latent latch
#

it's a pretty clean idea. The goal here overall is to reduce as much iterating as possible

spiral geode
#

so it's appropriate IMO that this should take only what it needs and should do so via an input param

latent latch
#

Both events and bitwise operations do remove a lot of it

spiral geode
#

whereas i'm commonly seeming people just reference mod inside a function that takes no inputs

#

it prevents you from encountering a bug, then saying to yourself "okay who is using mod 🤔 " and then getting annoyed tracking down all of its mutators

heady iris
#

that would make sense if there was a single mod field in your class

#

rather than grabbing the flags from the mod field and passing them to the method

#

one would wonder why that method is even attached to your class if it's not going to use the data from the class

spiral geode
#

ok well a good example is 95

# 
    protected AddAbilityStatMod(AbilityStatMod mod)
    {
        AbilityStatMod.Add(mod);
    }
#

this function cares about mod, and i know this by looking at the function signature

#

as opposed to just abusing () all over and tracking down all of your references inside the body of those functions

heady iris
#

i'm not sure how you could coherently write a function that adds a stat mod without a stat mod parameter

#

I would be annoyed if I had a method that took a bunch of parameters that turned out to just be fields from my class

spiral geode
#

where does mod come from on line 45?

heady iris
# 
public class Foo {
  private int bar;
  private GameObject baz;
  private Transform buz;

  public void Something() {
    DoThings(bar, baz, buz);
  }

  private void DoThings(int bar, GameObject baz, Transform buz) {
    // ...
  }
}
#

this would not make any sense to me

#

unless, of course, DoThings could be meaningfully called with different values

spiral geode
#

i dont see the original reference to mod, maybe im blind?

heady iris
#

seems like a typo from line 43, since mods is the wrong word for a single AbilityStatMod

latent latch
#

im typing this all in notepad++

spiral geode
#

so 45 is supposed to be mods?

latent latch
#

lol

#

the actual class is full of generic constraints so had to chop up a bit

spiral geode
#

ah i see

#

are you using notepadd++ instead of visual studio?

latent latch
#

yeah I see some typos

spiral geode
#

like for the actual game

#

when you open script from unity

latent latch
#

oh, I'm just using notepad++ just to ignore the ide warnings of simplifying names and such

heady iris
#

trying to simplify code to show it to someone usually just makes it harder to understand :p

#

code usually exists for a reason..

latent latch
# 
    public abstract class BaseAbility<SO> : Storable<SO>, IBaseAbility<SO> where SO : IBaseAbilitySO

Well, that's the prototype of the class

#

along with some covariance interface

    public interface IBaseAbility<out SO> : IStorable<SO> where SO : IBaseAbilitySO```
#

I should start commenting more cause im looking at this like where the heck did I leave off

im not familiar with the type parameterization. what does <out SO> do here?

heady iris
spiral geode
#

oh so C# has a kind system?

latent latch
#

I gotta run into the problem why I use it again to explain it

spiral geode
#

that looks like a higher kinded type

latent latch
#

but coupling classes by a data class constraint creates problems for me

heady iris
#

Covariance and contravariance allow you to use more or less derived types

#

Covariance means that you can return something more specific than your generic type requires

#

And contravariance means that you can accept something less specific

latent latch
#

what it allows me to do is keep the scriptable object variable declaration as the exact type that it's coupling with instead of a upcasted version

heady iris
#

So your interface that demands you to return Parent can be satisfied by a class that actually returns Child

#

after all, you can freely reinterpret Child as Parent to satisfy the interface

spiral geode
#

i just learned about this from that book

[RequireComponent(typeof(PlayerAudio), typeof(PlayerInput), 
typeof(PlayerMovement))]
heady iris
#

but then, if you use the type directly, you can get a more specific type returned

spiral geode
#

(this being unrelated to variance, just thought it was neat)

latent latch
#

You'd probably run into a similar problem if you designed a hotbar that can include multiple different types.

spiral geode
#

ok here (from book) is another example of a scenario where i am a little confused

[RequireComponent(typeof(PlayerAudio), typeof(PlayerInput), 
typeof(PlayerMovement))]
public class Player : MonoBehaviour
{
 [SerializeField] private PlayerAudio playerAudio;
 [SerializeField] private PlayerInput playerInput;
 [SerializeField] private PlayerMovement playerMovement;
 private void Start()
 {
 playerAudio = GetComponent<PlayerAudio>();
 playerInput = GetComponent<PlayerInput>();
 playerMovement = GetComponent<PlayerMovement>();
 }
}
public class PlayerAudio : MonoBehaviour
{
 …
}
public class PlayerInput : MonoBehaviour
{
 …
}
public class PlayerMovement : MonoBehaviour
{
 …
}

he expresses movement, input, and audio as classes. Why not using separate scripts called PlayerAudio, PlayerController, etc?

#

why one over the other?

#

this is the kind of stuff that (at my beginner level) is confusing to me

#

or maybe that's what's being represented with this single file

leaden ice
spiral geode
#

yeah you're right

leaden ice
#

And under no circumstances would you put all those in one file

#

that's probably just shown that way for convenience

#

they'd each have their own file

spiral geode
#

they are just jamming shit all over

leaden ice
#

this is why I avoid "courses"

#

they're generally shit

spiral geode
#

leaden ice

learning from experience is better

rigid island

it wouldnt even compile properly

#

the guy that wrote this "official" unity ebook that was recommended on here has a course

#

that @rigid island linked

#

it hasnt been updated in 4 years, though

rigid island
#

just cause they wrote a unity pdf doesn't mean their courses are any good 🤷‍♂️

spiral geode
#

i'm assuming that unity vetted this ebook before they put their golden stamp on it

#

if not, then i'm wasting my time reading it

rigid island
#

just saying the ebook isnt a voucher for the course quality 🤷‍♂️

spiral geode
#

right, makes sense

rigid island
spiral geode
#

he made some courses and he's got some instructional business called GameAcademy I guess

#

then he got consulted to write that book apparently

unity is looking for a single class in each script asset

latent latch
glossy wave
#

Hello! How would i instantiate a gameobject at the location where a SphereCast hit a collider?

jagged snow
#

What does this part mean or do? where T : BTNodeBase, new()

heady iris
#

Unity doesn't actually care about exactly what class a component is made from. It just cares about the script asset.

#

So you can rename a script asset and change the class name, and all of your components still work.

heady iris
#

It's listing things that must be true about the type

leaden ice
heady iris
#

new() is useful if you want to be able to construct instances of T

jagged snow
#

ahhh ok

heady iris
#

without that, there's no way you could prove to the compiler that T can always be constructed

jagged snow
#

T : BTNodeBase, new()
so everything after T is the conditions required. What if the conditions are not met? Will it throw and error in unity or just return and do nothing?

Without new(), it would be impossible to ever write a class that constructs an instance of T

unborn flame

because the compiler could not be convinced that you can do that

leaden ice

#

ill probably want to look into that since first time seeing it

heady iris
#

I wonder if you have three clones right now.

#

(one would then be stuck under the player, moving at incredible speed)

unborn flame
heady iris
#

Check that the instances actually have the correct speed value

#

if they exist in the scene, they could have had an override set for that field

leaden ice
#

Yep - show the inspector of one of the instances at runtime

unborn flame
leaden ice
#

it's also unclear how targetposition is being set

unborn flame
unborn flame
leaden ice
#

show them in edit mode

#

if they're not there in edit mode then you have some other code setting it

heady iris
#

you can't see overrides in play mode

#

because the prefabs have been unpacked

I'd like to use a line renderer to write the title of my game in cursive on my game's title screen. Is there a way to do this without having to input every position manually?

lean sail

You'll need a line renderer per letter though or itll be one continuous line

Doesnt really matter since you're just gonna do it a few times and be done forever

My project uses some google apis that use Newtonsoft.Json There isnt any problem with this in the editor or when compiled for pc. However I get console errors when I use WebGL. to get around this I have turned code striping to minimum in the player settings. now I don't get console errors but the code does not run as intended> When I run a function that uses newtonsoft.json the webpage freezes. Any suggestions?

somber nacelle
#

you check the dev console to see if it spits out any errors?

faint brook
#

Yeah. right before I make the api call I print out a "here" and that is the last thing that happens before the freeze

somber nacelle

well then you probably need to provide more context 🤷‍♂️

As well as the Get method.

#

What does request.Execute do?

faint brook
#

I believe the get method forms a http request that includes some authorization info and the request.Execute preforms this

cosmic rain
#

I'd imagine that it uses threads, which is why it fails.

faint brook
#

ugh why must so many data base options not work with webGl

cosmic rain
#

Because it's literally running in the browser, that imposes many restrictions on the app.
Your best bet would be using web API for the google spreadsheets and not the dot net client.

#

I tried that but couldnt figure out how to incorprate the authentication

#

I might just make a seperate database and host it locally

yo
say i have a List of lists with [ [1,2,3,4,],[7,8,9] ]
and i want to add a list [1,2,3,4,5] to it but i want to detect overlaps and add to it so that the resulting list of lists will be:
[ [1,2,3,4,5],[7,8,9] ] (as apposed to [ [1,2,3,4,],[7,8,9],[1,2,3,4,5] ])
more directly what I'm trying to do is... I'm making a match 3 game where you can move pieces after youve already made a match but whenever i add a new element to a existing set of matched elements, it basically resubmits the whole group of matched elements to the list of existing matches leading to duplicates and trouble finding out how many separate matches were actually made... and I'm trying to fix that

cosmic rain
latent latch
#

knowing c#, there's probably a single method made for this lol

#

but I'd just keep everything sorted, then forloop after finding the first element in each list

cosmic rain
latent latch
#

oh yeah, I guess another requirement is where that 5 should go, but it seems that we'd just add it to the first list it can be inserted into

            overlappingResult.vertMatches = overlappingResult.vertMatches.Union(newResult.vertMatches).ToList();

#

If duplicate values not allowed then why not just store them on single list and have an additional int for the actual list they are

cosmic rain
#

I really can't imagine a situation in a game where you would need to find overlapping number sequences in a raw fashion like that. I'm sure there must be some more context that you could use. For example, give your match results an id and update them by id.

#

You're not writing an accountant software. You don't need to make your life harder on purpose.

#

I wanted to make the system modular and usable for basically whatever I need to, so I have a system where I have a List of all existing matches on the board each match being stored as a "match result" which contains a 2 lists of its horizontal and vertical matches each which are stored as a references to each one of the elements in that match

cosmic rain
#

I don't see how adding a generic identifier makes it less generic/modular.

#

Also, making modular systems is great, but don't make it the sole purpose sacrificing everything else(performance, readability, development time)

If lists could only be a certain size I would personally make specialized structs to compare without allocating all these lists and stuff; but it's very specific to the game and familiarity with the type of approach. I personally find the idea of having so many hashsets and lists a bit of a nightmare idea

Can anyone help me with this? I want to wrap my player character around the screen edges. When he hits the left side of the screen, I want him to appear on the right side in the same vertical position. My scene is set up so that the player only moves in the x and z planes, and the camera is tilted 45 degrees on the x-axis. But my code can only transfer player character to the center of the screen.

before that would of been considered 2 matches becuase the first match of the 4 orange elements and then it subjects a second containing all 5

There are more and better ways to optimize it if you really need to. For starters implement it as simple as you can.

If you have pattern eg AAABBCCBD

Rigidbody player controllers are just bad. People use them because for some reason tutorials are almost always with them. But always at some point you hit a case where you want your player to move in a non physics correct way and that is hard to achieve with a rigidbody.

#

Most games out there use some form of a kinematic character controller

cosmic rain
#

I don't see a problem with using an rb. You can do all the same + rely on unity physics when needed.

cosmic rain
#

I've had to deal with a few kinematic controller assets, and I must say they have their own problems, so it's not as simple as just not using an rb.

Hiii is there an easy way to remove all delegate listeners or do I have to manually remove them all? ^^

#

Or can I at least just set the delegate thing to like null or something

somber nacelle

If it is a normal delegate then just assign null. If it is a UnityEvent then call RemoveAllListeners on it

thanks!

In Unity what is the name of a function/method/event that can be triggered and you can subscribe to

In UE its called Event Dispatchers if this can help

Maybe UnityEvent?

hey guys! To the peeps who've used timelines before, how performance friendly is it? I'm halfway into making a custom track for it that takes in dialogue so I can give story segments in game some life-- but it just dawned on me that maybe having all these clips might have us run into performance issues. For context, we're hoping to have this run on mobile/school laptops.

I'm not pressed if I have to rethink how I'm handling this, but I'd like to at least know if it's worth it continuing with the timeline idea ^^,

latent latch
#

timeline itself is just a bunch of keyframes that are lerped over curve values

#

so that's probably very miniscule, so if there are performance problems then it would be more related to the assets that you may be using such as audio

round violet
latent latch
#

what im saying is you'd run quicker into having too many assets loaded in than a bunch of keyframes from your timelines
