[clear oriole]

The goto statement can lead to code that is difficult to read, understand, and maintain

[calm talon]

I am such an idiot

that's why the code no work lol

[shell scarab]

I'm writing a light level gen script for a prototype. In the first part of the while loop I basically set up some variables I need. In the second half I use a random instance to get up down left or right, but up down left or right may be taken, so I basically just say if right is already generated but I know that some combination of up, down, left or right is open for the current cell, goto the line where a random direction is gotten instead of restarting the loop and regenerating all the variables I need (which were already generated and would generate to the same value if restarted).

[clear oriole]

also the goto can introduce potential bugs and errors as it allows for non linear program flow which can make it difficult to reason about the state of the program at different points its just not great to use "All the time" but i mean once or twice i dont see why not

[shell scarab]

idk, goto seems stigmatized. It's still pretty linear unless you have gotos stringed together.

[clear oriole]

Well sure the goto is linear but it makes other code not linear

[calm talon]

I've literally only used it for breaking out of multiple loops at once tbh

[shell scarab]

i mean, only if you use it like that. I've only really seen cases to use it when you absolutely need to break out of multiple loops with it, or when you want to repeat only part of a method but it would be unreasonable to move that part into its own method or local method.

[clear oriole]

it just makes the code less structered really and when you start getting lots of scripts it can build up really fast and it can just cause a lot of issues down the road but its not a terrible thing to use, just has to be controlled

[shell scarab]

well I get what you're trying to say I think, but what issues?

I mean anything can cause issues down the road.

[clear oriole]

well it creates spaghetti code which makes readability pretty hard which is where the control part has to come in, and the go to statement can cause many unintended bugs and debugging go to statements can present more of a challenge especially without proper commentation and jumping to different parts of code like that might cause values to not be correct depending in the circumstance, and the go to statement may not be supported on other platforms.

But to be fair everything comes with its list of issues

Im only fimiliar with windows and mac so i couldn't tell you what platforms but there are things like that, that wont work on mobile devices

Idk if possible i would find a better alternative to your problem if possible if all else fails screw it

[somber nacelle]

#archived-networking
also the only answer worth anything is "do your own research and determine which networking solution best fits the needs of your project"

also DOTS is not networking

[nimble cairn]

Is GameObject.CompareTag("x") == "x" still better to use than gameObject.tag == "x" in 2024?

[somber nacelle]

the CompareTag method is always going to be better than string equality. also it's just gameObject.CompareTag("x") not gameObject.CompareTag("x") == "x"

[nimble cairn]

Yep!

Thanks

@somber nacelle What about in this instance.

Do you see any room for improvement?

Surely this is better, having a bit of GC once than all the overhead of compare tag multiple times

[quartz folio]

1. local variables should not be prefixed with underscores
2. why's the highlighting so bad? Is VS Code actually configured?
3. you can get transforms directly from components, you don't need to go through the gameObject
4. bridgeParent should just be a Transform if that's what you care about, unless you use it for GameObject-specific things, just use the type you care about

[somber nacelle]

the main benefit of using CompareTag is that it provides relevant errors when you have misspelled a tag instead of just failing silently. the slight performance benefit is really just a bonus

[quartz folio]

But yes, that is probably on par with CompareTag, but it avoids any warnings CompareTag gives when you're missing a tag

[nimble cairn]

@quartz folio

1. I know, however in this instance I prefer the underscore.
2. My configuration is fine -- omnisharp is not running so I could take a quick screenshot.
3. Can you elaborate?
4. I've experimented with both Transform and GameObject and GO is just easier for this method.

[quartz folio]

- col.collider.gameObject.transform;
+ col.collider.transform;

Ah I was wrong on 4, you declare it right there. I thought it was a serialized reference for a moment there

[nimble cairn]

Oh, that's a neat little hack

[rigid island]

2. your config doesn't look fine

[nimble cairn]

I need it to be like that :p

[quartz folio]

If they're aware omnisharp is not running, it's fine

[nimble cairn]

Please refer to my second point -- omnisharp is not running I just opened VSCode for a quick screenshot!

Point 4 is how it is because sometimes the class is within a parent that has a rigidbody, and referencing the transform like that ensures there is no missing reference 🙂

[rigid island]

I see, hmm c# DevKit should still recognize the solution 🤷‍♂️

[nimble cairn]

I don't have the dev kit installed

I don't need it

[rigid island]

then you don't have intellisense + unity 🤷‍♂️

[nimble cairn]

I sure do 🙂

@quartz folio @rigid island @somber nacelle Thank you for your assistance and queries!

[rigid island]

you do ? bcuz devkit is part of the Unity extension

[nimble cairn]

You don't need it!

[quartz folio]

Unless you're on an old Unity version or something, pretty sure you do

[nimble cairn]

.NET Install Tool and the C# extension are all you need

[rigid island]

say what now

[naive heron]

how do i instantiate an object under a parent so it follows them when its spawned

[quartz folio]

https://code.visualstudio.com/docs/other/unity

[somber nacelle]

pass the desired parent as the last parameter for Instantiate

[nimble cairn]

@naive heron

GameObject parent = new GameObject("Bridge");
child.transform.SetParent(parent.transform);

@quartz folio I don't know what to tell you, it works perfectly fine and I have minimal bloat packages.

[quartz folio]

If you have the Unity extension installed—which you should, then it'll have added it as a dependency

[nimble cairn]

No unity related extensions

On VSC

[rigid island]

curious to see how it is "working perfectly"

[nimble cairn]

I'm starting her up now, I'll prove this

[quartz folio]

the ol' no access to a debugger, and no refactorings or analysers

[nimble cairn]

I can debug just fine 🙂

[quartz folio]

That's not a debugger, that's just autocomplete

[rigid island]

also missing some other stuff

[nimble cairn]

I know, you were initially asking about the intellisense

[fervent furnace]

if CompareTag("XXXXX") is faster than "XXXXX", then you run =="XXXXX" for n times means it is n times slower than running CompareTag("XXXXX") for n times............

[quartz folio]

CompareTag is faster only because the managed string needs to be allocated with tag, which they only do once

[fervent furnace]

just depend on how comparetag implemented, i think they use unordered_map internally

not char by char matching

oh wait it still needed to get the hash code for two string then do one comparsion

[naive heron]

how do i get the desired parent because nothing im trying is working

[somber nacelle]

wdym how do you get it? do you not know what object you want the parent to be?

[nimble cairn]

@naive heron I already told you

[rigid island]

do you have a reference to the parent?

[nimble cairn]

public GameObject cykaBlyatParent;

[naive heron]

i tried to implement that and couldnt figure it out

[naive heron]

yes as fpsCam

[nimble cairn]

There's nothing to figure out

Send your code

[somber nacelle]

you don't need what they suggested. there is an overload for Instantiate that accepts a parent transform

just pass the object's transform for that parameter

[nimble cairn]

@somber nacelle I think that might be a bit complicated for their skill cap

[naive heron]

how 😭

[somber nacelle]

what you suggested is going to confuse them even more considering they probably have a prefab that they are trying to instantiate and don't just want a blank object

[somber nacelle]

have you looked at the docs for the Instantiate method?

[naive heron]

yes

[somber nacelle]

okay so show what you tried

[naive heron]

private void Update()
{
playerpos = playerModel.transform.position;
}
Instantiate(reloadPlayer, playerpos);

[naive heron]

its in a function but ye thats basically it

[somber nacelle]

well for one, you have to pass a transform as the parent. two, if you want to pass a position, you also must pass a rotation, then the parent transform will be the last parameter

[nimble cairn]

If you're struggling to parent a transform..

No offense! Just want to help of course 🙂

[nimble cairn]

You need to reference the Instantiate

GameObject GO = Instantiate(reloadPlayer, playerpos);
playerpos.SetParent(GO);

[rigid island]

this is wrong

[naive heron]

thank you

this is what i did to fix it|
Instantiate(reloadPlayer, playerModel.transform.position, Quaternion.identity);

[somber nacelle]

well that just sets its position, it does not set its parent

[fervent furnace]

https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

[naive heron]

its working anyway so idc

ty

[somber nacelle]

you need to pass the playerMode.transform as the last parameter as i've said before

[somber nacelle]

you explicitly stated you wanted it to follow the desired parent object. this will not do that

[fervent furnace]

you probably want this

public static Object Instantiate(Object original, Transform parent);
```or this
```cs
public static Object Instantiate(Object original, Vector3 position, Quaternion rotation, Transform parent);

[naive heron]

i wanted to make the instantiated object follow a different game object and i assumed that parenting was the only way

[leaden ice]

so... parent it

[naive heron]

sorry but thx

[rigid island]

if you move you lose position unless parented

[naive heron]

its working already tho

[somber nacelle]

well unless you have some other code somewhere that makes it follow it, then parenting it is the only way

[nimble cairn]

How?

[leaden ice]

doubt

[rigid island]

because the way boxfriend suggested does it in one line ?

also ur parenting it twice

[leaden ice]

this would be a compile error. It also makes no sense. playerpos is a Vector3

[rigid island]

and this^

[nimble cairn]

Fair enough

[fervent furnace]

there is no overloaded version of instantiate takes only the object and one vector3...

[dark kindle]

does anyone have a workaround for windows' X509 api? I have code to get a list of all certificates in a store: ```

    X509Store s = new X509Store(StoreLocation.LocalMachine);
    s.Open(OpenFlags.ReadOnly);
    foreach (X509Certificate2 c in s.Certificates)
    {
        UnityEngine.Debug.Log("cert: "+c);
    }

but it doesnt work

essentially it supposed to go to the local machine certificate directory on Windows and prints all the certificates

[leaden ice]

Elaborate on this? What happens?

[dark kindle]

I dont see anything printed

that

s the issue

thats the issue

I checked certmgr and im sure I have certificates on my system

The code isnt picking them up.

[frail nest]

Hi, I wonder if should I destroy any created sprite? Or the GC will take care of it automatically?
Like

Sprite sprite = Sprite.Create(texture2D, new Rect(0,0,200,200), Vector2.zero):

[leaden ice]

How do you know the code is even running? Print the length of the collection

[leaden ice]

You must Destroy any UnityEngine.Object you create, aside from GameObjects in a scene which will be destroyed with the scene unloading

[frail nest]

alrighty thanks

[frail estuary]

How to freeze Spring Joint movement from side to side only to leave up and down ?

[frozen fjord]

I need help I'm having wayyy too much trouble placing blocks in a minecraft clone

My placeblocks method looks like

    private void PlaceBlocks()
    {
        if (Physics.Raycast(Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f)), out var hitInfo, reach, blocksMask))
        {
            Vector3 vector = new Vector3((int)hitInfo.point.x, (int)hitInfo.point.y, (int)hitInfo.point.z);
            vector -= playerTransform.forward * 0.001f;

            worldManager.GetChunkByBlock(vector).SetBlockAt(vector, BlockData.GlassBlock, transparent: true);
        }
    }

i put line 6 to sorta move outside the block

    private Vector2 RoundToChunkPos(Vector2 pos)
    {
        return new Vector2(Mathf.FloorToInt(pos.x / 16f) * 16, Mathf.FloorToInt(pos.y / 16f) * 16);
    }

    public Chunk GetChunkByBlock(Vector3 blockPosition)
    {
        return chunks[RoundToChunkPos(new Vector2(blockPosition.x, blockPosition.z))];
    }

[leaden ice]

1. Raycast
2. Calculate the grid coordinate of the block you hit
3. Calculate the new grid coordinate by adding one to the existing block grid coordinate in the direction of the Raycast hit normal
4. Place block at that calculated grid coordinate

[frozen fjord]

i wanted to see if you guys saw anything wrong

[leaden ice]

You're doing really fuzzy stuff with the player look direction etc. that's going to be janky

[knotty sun]

use Vector3Int to make sure no fp errors creep in

[frozen fjord]

public void SetBlockAt(Vector3 pos, int blockType, bool transparent)
    {
        int blockIndexX = (int) (Mathf.FloorToInt(pos.x) - transform.position.x);
        int blockIndexY = (int) Mathf.FloorToInt(pos.y);
        int blockIndexZ = (int) (Mathf.FloorToInt(pos.z) - transform.position.z);
        Block block = blocks[blockIndexX, blockIndexY, blockIndexZ];
        block.type = blockType;
        block.transparent = transparent;
        BuildChunkMesh();
    }

[leaden ice]

If you're not working in the realm of discrete grid coordinates you need to throw all your code away and start doing so

[leaden ice]

Should just straight up be using Vector3Int

[frozen fjord]

oh yeah, i meant everything is in integers anyway but yeah

[frozen fjord]

now it's trying to die 😭

idek what's happening

the y coordinate is right

everything else is wrong

my game

is trying

[leaden ice]

My recommendation remains this: #archived-code-general message

[frozen fjord]

to die

[frozen fjord]

i guess i'm too dumb rn to know how to do step 2-

what am i doing 😭

[leaden ice]

The stuff you're doing isn't even taking the Raycast hit normal into account, no idea how it can work without that

[leaden ice]

That's like the most fundamental function you should have in a Minecraft game

[frozen fjord]

Vector3Int vector = new Vector3Int((int)hitInfo.point.x, (int)hitInfo.point.y, (int)hitInfo.point.z);

is this proper for now

i mean

[leaden ice]

You need to lay a solid ground work of helper functions before you start adding features

[frozen fjord]

do you know how i should do this-

[quartz folio]

extension methods out the wazoo

[frozen fjord]

i'm trying to figure out where the issue is

i'm guessing it's in the calculation

i mean

[leaden ice]

Well the Raycast hit will be at the edge of the block

[quartz folio]

Draw some things in the scene using Debug.DrawRay/DrawLine

[frozen fjord]

does this look okay (Chunk class)

[leaden ice]

Usually you'd offset that by half a unit inward before converting to get the coordinate

[frozen fjord]

move it inside the block?

so like negative the surface normal

[leaden ice]

Yes

Or half a unit outside

To get where the new block should be

[frozen fjord]

because i'm placing a block :D

Vector3 vector = new Vector3((int)hitInfo.point.x, (int)hitInfo.point.y, (int)hitInfo.point.z);

should i

do that to this

[leaden ice]

Add half the surface normal

Then convert to frid coordinate

[leaden ice]

For God's sake use Vector3Int

[frozen fjord]

i thought i was moving it half a unit out

so i thought float yay

[leaden ice]

I'm saying offset before you convert to int

When you convert to int, then use Vector3Int

[frozen fjord]

oh

this is the vector I would be affecting

[leaden ice]

E.g. Vector3Int newGridCoord = hitInfo.point + (hitInfo.normal / 2);

[frozen fjord]

Cannot implicitly convert type 'UnityEngine.Vector3' to 'UnityEngine.Vector3Int'

[leaden ice]

I think there's an explicit conversion

[rigid island]

Vector3Int.RoundToInt

[leaden ice]

E.g. ```cs
Vector3 offsetPos = hitInfo.point + (hitInfo.normal / 2);
Vector3Int newGridPos = (Vector3Int)offsetPos;

[frozen fjord]

private void PlaceBlocks()
    {
        if (Physics.Raycast(Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f)), out var hitInfo, reach, blocksMask))
        {
            Vector3Int blockPos = Vector3Int.RoundToInt(hitInfo.point + (hitInfo.normal / 2));
    
            worldManager.GetChunkByBlock(blockPos).SetBlockAt(blockPos, BlockData.GlassBlock, transparent: true);
        }
    }

is that good

now I don't even know what's going on, it works sometimes but then it doesn't?

usually it works but then sometimes it'll decide to place blocks in the air

oh what is happening

[frozen fjord]

is it sorta possible to draw a box around the block it would be targeting

like in minecraft

[quartz folio]

You can draw anything using a number of lines

[frozen fjord]

More math lesgo

[quartz folio]

(They are editor-only lines) and I have a package that can draw more advanced shapes https://github.com/vertxxyz/Vertx.Debugging

[frozen fjord]

I wonder what I could print to check if it's working

[quartz folio]

You could use the debugger and just go over everything

there's rarely a reason to print when you can just look at variables and execution directly

[frozen fjord]

this is so dumb I'm printing values and I can't see a noticable difference between the times it placed it correct and wrong

wait

...it works now?

@quartz folio @leaden ice is this code good or stupid (it works)

      private void PlaceBlocks()
    {
        if (Physics.Raycast(Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f)), out var hitInfo, reach, blocksMask))
        {
            Vector3 vector = hitInfo.point + (hitInfo.normal / 2);
            Vector3Int blockPos = new Vector3Int(Mathf.FloorToInt(vector.x), Mathf.FloorToInt(vector.y), Mathf.FloorToInt(vector.z));
            Debug.Log("Point: " + hitInfo.point);
            Debug.Log("Half Normal: " + hitInfo.normal/2);
            Debug.Log("Sum: " + (hitInfo.point + hitInfo.normal/2));
            Debug.Log("Block Position: " + blockPos);
            Debug.Log("---------------------------");
    
            worldManager.GetChunkByBlock(blockPos).SetBlockAt(blockPos, BlockData.GlassBlock, transparent: true);
        }
    }

[sour atlas]

Not sure where the best place to ask this is - it's a Unity Native splines question. I would like to efficiently look up a point on the spline at a set distance away. GetPointAtLinearDistance returns the linear distance so is not what I need. I can walk the spline manually until I reach the distance I want, but this is super inefficient for lots of points... Am I missing a method somewhere? I need a parameterized version of the spline basically.

[knotty sun]

is the spline deforming after creation?

[sour atlas]

It can be yeah

[knotty sun]

so cacheing cumulative distances wont work?

[sour atlas]

Yeah that's my fallback - I can cache once and then use that cache for all the points. I'm just wondering whether that's being done internally somewhere

[quartz folio]

You can access ConvertIndexUnit from a SplinePath to convert between distances and normalized values

[sour atlas]

oooh ok, I'll check that out, thanks!

[sour atlas]

Ah wait no, the value I have is a distance, the value I want returned is t. ConvertIndexUnit will do the opposite?

[quartz folio]

It should, you pass the units from and to

just use the right overload

[sour atlas]

Ahh yes sorry missed the second method in the docs

[quartz folio]

I haven't used it that much, I just have a memory of using some jank conversion function in the past 😄

I looked at SpriteAnimate and noticed that's what it uses

[south cobalt]

Guys, first line of code is obsolete now, and i am not sure how to edit 2nd one properly so it works, can u help?

[sour atlas]

Yeah that's awesome, works fine. Thanks!

[rain lava]

Guys how can I be master at using events and delegates? They are core of game dev, i believe.

[knotty sun]

[cosmic rain]

You need to defeat the previous master in a fair combat.

I want a way to make all type of NPCs to look at the player when approached and salute them (salute code is in second pic). How do I do this?

Is there a way to make the NPBCrain abstract class already have the function in the second pic in it?

[fervent furnace]

abstract class can have non abstract methods

[twilit scaffold]

So i should learn DOTS and ECS, or have the changed the paradigm?

[long plover]

Would something like this work? I still have to fix in the errors, I was using a navmeshagent for the random wanderer NPC who stops when player gets close.
How can I achieve same condition about distance from this NPC to the player in the if statement?

[fervent furnace]

pass the parameters this method needs

and your method can return something

[long plover]

@fervent furnaceCan I add a start function to the abstract class?

I need to add the animator and transform

[fervent furnace]

your abstract class is ScriptableObject......
you can add what even you like

[long plover]

ohhhh, sorry for the stupid questions, I have not worked with abstracts much😅

[fervent furnace]

wait, your npc brain is scriptable object then you cant access the methods from monobehaviour

or inherit from it

[long plover]

oh

So what do I do? 🥲

I remember Fen sent me this code, does this help in any way?

[fervent furnace]

make your monobehaviour base class of other specific npc script eg

public class Letter:Monobahaviour
public class A:Letter

yes, put the common methods in the "top" most class

[long plover]

I will try that, 1 sec

[long plover]

Something like this? If so, where do I put ScriptableObject tag?

[fervent furnace]

npc inherits from npcbrain and npcbrain inherits from monobehaviour
i dk what you mean by ScriptableObject tag, ScriptableObject is a class

think in this way: inheritance usually means "is" (or are)
you are citizen and citizens are human

so
citizen:human
you:citizen

[autumn magnet]

GameObject gun = Instantiate(g);
DontDestroyOnLoad(gun);
gun.GetComponent<NetworkObject>().Spawn(false);
ConstraintSource src = new ConstraintSource();
src.sourceTransform = weaponHolder;
gun.GetComponent<ParentConstraint>().AddSource(src);

I am trying to spawn the gun prefab with this code that works fine but the issue comes with the ParentConstraint cause for some it does not follow the transform of WeaponHolder but whenever I change the index of it to 1 in runtime it does work -_-

[fervent furnace]

i realize that npc is not npcbrain, you can use composition instead (let npc stores one npcbrain)

[twilit tree]

Make sure the ParentConstraint is active, enabled and has weight at 1.

[autumn magnet]

is this correct ?

[twilit tree]

Make sure lock is enabled in Constraint Settings

[autumn magnet]

it is

[twilit tree]

src.weight = 1;

[autumn magnet]

lemme try

[autumn magnet]

oh that was it works now!
thanks

[long plover]

I am still a bit confused sorry. I need to make scriptableobject so I can create NPC SO for the different type of NPCs, also So I can add name, NPC type, etc

@fervent furnace I was watching this guide and was trying to follow it. https://youtu.be/0VV24g1SxGU?si=H0qMGDNselBu7E6b

[fervent furnace]

yes your npcbrain (or other class that stores data) is scriptable object
while the enemy in world store the reference to its scriptable object

[long plover]

So is my current NPCbrain a scriptable object?

[fervent furnace]

no, it inherit from npc and npc is monobehaviour

[long plover]

Now I am confused 🥲

So I dont have any SO?

I am trying to achieve something like this. Where I can make an SO of the desired NPC type (wanderer, teleporter, weaponsmith) and then the person adding these to the scene just need to give them a name, and maybe some other perimiter like teleport location, etc

@fervent furnaceI hope it makes sense what I want to achieve

I just dont know how to achieve it

[sonic notch]

I currently have a Crowd Simulator using RVO2 for Collision Avoidance and A* for Pathfinding. I'm in school and for my course I need to evaluate something so I need another simple collision avoidance algo to compare with the one I have. I want something as simple as possible because I just want to be done with this course and im stressed. What is something I can use for collision avoidance and use A* for pathfinding as well on it (not a must but probably easiest)?

Originally I was thinking Boids but Boids and pathfinding is basically mutually exclusive

Don't really have the time to deep dive and learn to how to implement something difficult and complex..

[foggy plaza]

I was using ScriptableObjects to hold and update stats of certain characters. Everything works okay.
But when I load those stats from a json file it works in the Editor, but not in the Build. Am I doing this wrong?

Even though debug messages show the correct values, in other areas of the game, the values are not correct in the Build.

[long plover]

How do I do this?

[fervent furnace]

use composition

[cosmic rain]

Any form of avoidance is mutually exclusive with pathfinding. You need to blend between the two.

[fervent furnace]

you can have enemy (monobehaviour) and data (scriptable object), enemy can store the data

[cosmic rain]

Hard to say anything without seeing your implementation.

[fervent furnace]

public abstract class Enemy:MonoXX{
  public data theData;
}
public class Enemy0:Enemy;
public class Enemy1:Enemy;

public abstract class data:ScriptableObject;
public class data0:data;
public class data1:data;
```then enemy0 and enemy1 can reference data0 or data1 (or not having data as abstract class if no more variations)

[sonic notch]

True, just feels quite inherently hard with boids since the whole point of boids are to just flock and follow average alignment etc. I guess you can override it with goals and obstacles changing the alignment

And if two groups meet i want them to avoid eachother but not merge

pass through basically

Im gonna try and just use the RVO I have but without A* and then just use rudimentary collision avoidance with like a raycast and then just rotate to the side if it hits an obstacle or something

[fervent furnace]

multi agent path-planning

then you dont need collision avoidance anymore

[long plover]

I hope you can bear with me, If we take it step by step. Is the following correct in the pic?

oh np-hard.....

do you know what is inheritance first? i think you dont understand it at all....

[long plover]

I understand the concept of it, but I am getting very confused while trying to apply it together with scriptable objects. I have used inheritence multiple times in previous java projects

For example I want to have this abstract NPCBrain class, where NPCWandererBrain and NPCTeleporterBrain inherites the Think and Salute methods from it. Inside the Think method each of those will use it differently

[fervent furnace]

think scriptable object not scriptable object, it is just some base class
then you can reference it without care what it exactly is

public class NPCBrain:magicalclass{
  public abstract returntype think(parameters);
}
public class ActualNPC:monobehaviour{
  public data theData;
}

[sonic notch]

If you are using raycasts for collision detection, do you create a new one every update? I assume so, just wanna check so Im not "Ray ray = new Ray(transform.position, transform.forward);" every single update unnecessarily.

[fervent furnace]

public class NPCWandererBrain:NPCBrain;
public class NPCTeleporterBrain:NPCBrain;
```assume they both implement think(), then in ActualNPC:
```cs
var result=theData.think(parameters);

[long plover]

@fervent furnace I kinda understand what you are getting at, for me the class names are a bit confusing. Is it possible for you to use my class names in instead of those? I think it will greatly help me understand

[leaden ice]

If you want to get the current position/direction of the object, you will need to do this every frame yes

note that Ray is a struct. Structs are stack allocated and will not create garbage for the GC

[fervent furnace]

scriptable object has nothing to do with how you organize the inheritance tree of different object btw

[long plover]

What is magicalclass here?

[long plover]

ohhhh

[fervent furnace]

scriptable object

it just add an additional root to your tree for unity to use your objects

[long plover]

Is this better?

Another Splines question ( @quartz folio ?) - I can get callbacks from EditorSplineUtility.afterSplineWasModified when the spline container is on the same gameobject as the script with the custom editor... However what I want is callbacks from a spline that is referenced by the script, and I can't see a way to pass the target spline to EditorSplineUtility.afterSplineWasModified?

[fervent furnace]

yes, something likes that

btw i think it is better to let the NPC having variation not the data, but idk what your game design is

[long plover]

I just want it to be simple. So I have this soldier NPC that I want him to have a couple of different types, like Wanderer (who move randomly, like this guy in the pic) then a teleporter guy (you interact with him and he will teleport you to a location)

Im trying to evalute two different crowd simulators for school. One I'm using is much more complex and the other is simple. The complex one seems to move slower and slow down as it gets further along (seems to still be smooth but the agents move slower) I'm assuming this is due to it being more complicated so lower fps. I'm thinking of just counting FPS instead and using that as the metric for how long it takes agents to get from A to B with the two different algorithms. Since one will in real time be much slower but will actually probably be better in terms of how efficiently the agents move, does this seem reasonable?

For the informed im using A Star with RVO2 in one, and just A Star in the other. Obviously the one using RVO2 is the slower one in realtime.

But yeah, assuming FPS is good metric that connects them

[leaden ice]

FPS would be a measure of how quickly your computer can run the algorithm

It doesn't say anything about how good the pathfinding is

which I imagine is what you're actually trying to measure?

It's unclear what you're comparing

computational performance, or the quality of the paths generated

A* is a general purpose pathfinding algorithm which will always find the shortest possible path (guaranteed unless your heuristic function doesn't conform to the requirements)

RVO2 is more of a navigation algorithm with collision avoidance iirc

[hard viper]

Stopwatch class is a good tool to measure how long a given evaluation takes, and is a better measure for just one specific thing.
But praetor is right that it’s not clear what you are looking for.

Stopwatch just requires you to be able to clearly define a line of code when you start and another line when done.

[unique delta]

When i start the game prefabs are invisible on the ingame camera but i can see them in scene. Can somone help me ?

[leaden ice]

sounds like they're not actually in view of the game camera

perhaps they're behind it for example

[normal quest]

assuming you are on 2D, check their z position

[unique delta]

thanks

[sonic notch]

Yeah I'm having a hard time finding a way to measure in time how good a crowd sim is since the computer plays a part. I have two, and I want to measure in time efficiency how long it takes for one to get to its goal, so lets say two groups of 5 passing eachother to get the other side.

A crowd sim using only A star will deadlock a lot and take longer since it won't avoid other agents/characters. But the one using RVO on top of A star will be faster. But my computer however will take longer to simulate the RVO one, since its more complex. So in Real time it will appear slower, even though it isn't. Basically the agents move much slower in the RVO one because its slower to calculate each timestep.

[leaden ice]

So again you need to decide if you're comparing computational efficiency or navigation quality or something else

[sonic notch]

Navigation quality

[leaden ice]

What you can do is just use an in game timer e.g. in FixedUpdate

float timer;

void FixedUpdate() {
  timer += Time.deltaTIme;
}```

[hard viper]

you need a metric for navigation quality then, friendo

[leaden ice]

use this in game time to measure how fast the things navigate

if you don't care about actual real time running speed this is ideal

[sonic notch]

Yeah but the further along the sim it goes, the slower the agents move because more calculations need to be made. Thats just because of my computer

not the algorithms theoretical movement

[leaden ice]

this will account for that

that's why we are using an ingame timer

not a real world timer

[hard viper]

i would use Stopwatch for that tbh

[sonic notch]

Oh it will? But not if its in Update right?

[leaden ice]

stopwatch uses system time

[leaden ice]

update should actually work as well

but generally simulation style things should be using FixedUpdate or an equivalent anyway

otherwise they may be inconsistent

[hard viper]

Time.time will use ingame time, and inlcude time spent on other tasks, like overhead and rendering, and managing scripts etc.

i think you would need
System.Diagnostics.Stopwatch sw = new();
sw.Start();
CallMyExpensiveMethod();
Debug.Log(sw.Elapsed….formatting);

to isolate just the CPU cost of the one expensive method that doesn’t take a whole frame’s computational time.

[sonic notch]

Hm I'm a little confused between the two approaches. Im not trying to evaluate how fast a certain method is, I'm trying to evaluate in a consistent way, how long it takes for my simulation to finish its goal, from A to B, even though how fast the agents move varies depending on where it is in the simulation. Since in the beginning its pretty fast, and the further it gets they move slower, and then start moving faster at the end when some agents finish up. But the time should be consistent through all of these, i dont want it to count as if its taking longer just because the agents are slowing down.

[tawdry jasper]

I'm using this code to read the ground color to determine footstep sound

            Texture2D texture = renderer.material.mainTexture as Texture2D;
            Vector2 pixelUV = _pushing.groundHit.textureCoord;
            Color pixelColor = texture.GetPixelBilinear(pixelUV.x, pixelUV.y);

this works fine in editor, but I just tried building an executable (on osx) and I see in the logs that the color I'm getting back is just "(0, 0, 0, 1)" is there anything special I need to do with materials / textures to do this in the executable? I had to mark the texture as readable in import settings to make this work in the editor, but unity gave me an error suggesting that, in the executable it just gives the wrong value

[sonic notch]

Since they are only slowing down due to the complexity of the code getting more and more demanding in the middle of the simulation.

[hard viper]

both are just ways of measuring time

Stopwatch measures system time between two points of code.
Time.time will get you ingame time for a frame

so if one frame takes 12 ms and another takes 130 ms, Time.time will tell you that

if you want to isolate just the amount of system time it takes to execute a block of code, you start a stopwatch, run the code, and then see what is on the stopwatch

does this make sense?

Time.time is slightly decoupled from realworld time. System time is basically looking at how many clock cycles your processor took between lines A and B

[round violet]

what should be added ?
com.unity.cinemachine only shows certain methods, but will still recognize the missing ones like CinemachineVirtualCamera

[leaden ice]

But I thought we were interested in the actual simulation-time navigation speed/duration of the characters, not the execution time of the algoriuthm

[hard viper]

i thought he wanted to know about how fast his algorithm executes to compare two algorithms

[long plover]

Trying to give my Teleport Location as a Transform parameter in my SO. It doesnt work?

[fervent furnace]

you cant reference anything on screen in asset

[hard viper]

SO always exists. Transform is a component on a gameobject that only gets instantiated during runtime

[long plover]

Wait, so how do I achieve this? 🥲

[fervent furnace]

so pass it as parameter, as what i told you

[round violet]

sorry if not, but are you talking to me ?

[hard viper]

SO cannot hold a transform well because the SO can exist when the transform does not yet

[leaden ice]

Assets can't reference objects from the scene

[hard viper]

you need a different way to reference that position

[long plover]

Not sure how to 🥲

[hard viper]

there are many ways

[long plover]

Where would I do that?

[hard viper]

bottom line is: SO should only reference something that always exists

eg int teleporter ID. Then have a monobehaviour that searches for the gameobject/transform that matches that ID

that isn’t the only way, but there are many ways

[long plover]

Can you explain more about this? I am really not sure how to do that

[hard viper]

i gave my SO a field for something that only exists at runtime. I made it work through lots of patching, but it was a really incredibly stupid idea

[hard viper]

make a singleton that manages all teleporters, and puts them into an array by ID. And let every teleporter have an ID. Write the ID into your SO.

singleton can connect teleporter to SO now

[icy herald]

Can someone help me with a button? I used this code before adding the ability for the box to press the button. But now, every time my player moves away, the button deactivates, even if the box is still there.

[long plover]

1 sec, I will look up how to do that

[tawdry jasper]

Since I'm using flat shaded assets and the color / uvs aren't interpolated I though I'd getaway without calling getpixel. So now I just examine the uv coords to determine the color, and again this works in the editor, but in the build executable RaycastHit.textureCoord comes back as 0,0???

[tawdry jasper]

ah now that the problem is reading uv's and not the texture I could find an answer: https://forum.unity.com/threads/raycasthit-texturecoord-working-perfect-in-editor-defaulting-to-0-0-in-build.1140568/

[long plover]

This stuff looks too advanced for me 🥲

[soft chasm]

General Question: What would be the best way to handle Pokemon style gameplay? Not the turn based stuff, I'm more meaning the way they handle movement and gameplay. As in, they move around in a 2D top-down world and then enter battles which takes them to an entirely different screen dedicated to the battles.

If I was to recreate that idea of gameplay (switch between movement and battle), what would be the best way to do this? To have the 'battle' screen be GameObject overlaying the main scene and just SetActive(true/false) a parent to enable/disable the battle screen - or have the battle happen in a different scene altogether. Would there be any advantages/drawbacks to either?

I understand I'm asking a rather vague question of a rather in depth mechanic, a generally vague answer will also do just fine 👍

[long plover]

Is there a way without singleton to just hardcode 1-3 teleport locations and then in the SO you select one of them in a drop down menu like:

TeleportLocation: {Homebase, Firing Range, Arena}

If so, what class do I put it in?

[leaden ice]

you'd use an enum for this.

// Define the enum
public enum TeleportLocation {
  Homebase,
  FiringRange,
  Arena
}

// make a field of that type
public TeleportLocation location;```

[long plover]

How/Do I give the coordinates of those locations in the Start()?

[leaden ice]

why in Start?

why not something like:

Vector3 GetPosition(TeleportLocation location) {
  switch (location) {
    case TeleportLocation.Homebase:
      return new Vector3(0, 5, 10);
    case TeleportLocation.Arena:
      return new Vector3(5, 1, 6);
    // etc...
  }
}```

[long plover]

ohhhh, that looks very good

[long plover]

I wasn't sure, my brain is melting and I have my exam tomorrow 🥲

[long plover]

Not sure how to fix these mistakes

[vagrant blade]

transform is a property of a game object, your location is an Enum type

And your GetPosition function doesn't return in all cases, you need to include a default: to your switch statement.

[leaden ice]

the errors are pretty clear I feel 🤔

why are you tryin gto do location.transform.positon (which makes no sense??) instead of calling the function we just wrote?

[long plover]

Like this?

[long plover]

Yeah sorry, my mind cant focus much at the moment haha

[fervent furnace]

do you know what is enum

[dark kindle]

I did, but it printed out nothing

I tested in another engine, and without printing length I was able to get output

[leaden ice]

https://issuetracker.unity3d.com/issues/x509store-is-empty-in-unity-but-has-certificates-in-pure-c-number-console-application

looks like you'd have to use a native plugin if you want this information

[dark kindle]

thank you for the reference. yes, in my case i have to use Unity so that is a good suggestion

it's a big component of my project so it kinda sucks

[round violet]

So i used this Unity docs example so I could "make" a dict in my inspector, all worked fine until i tried to edit the list after i compile after correcting an error.
now i cannot add items, but i cant still remove

here is my code and inspector:

[mellow sigil]

What happens when you try?

[round violet]

nothing

just me pressing the "+" icon

[leaden ice]

your code won't let one of the lists be longer than the other

it will only iterate up to the min of the two

I wouldn't use two separate lists here

I would use one list containing a struct with both the key and value data in it

[hard viper]

I would like to request feedback still, on the topic of: does this sound like a good system to use for collectibles?

[round violet]

its weird Untiy showcase a code snippet with this limit

[mellow sigil]

The docs example isn't complete. It just shows the gist of it.

[round violet]

i'll try ty

[long plover]

I do know what it is and have used it before, doesn't mean I can focus well with a strong migraine, I just need to finish this code ASAP so I am ready for my exam tomorrow

[long plover]

@leaden ice@vagrant blade I am a bit lost with trying to make my enum list showup in the inspector for the SO

https://youtu.be/ErJgQY5smnw?si=kkKniCSOwqiw7Ml-

you should use this singleton implementation

very simple way to implement singletons in unity

[heady iris]

I have multiple kinds of singletons (how ironic)

using UnityEngine;

public abstract class SingletonPrefab<T> : MonoBehaviour where T : SingletonPrefab<T>
{
    private static T _instance;
    public static T Instance 
    {
        get
        {
            if (_instance == null)
            {
                _instance = Instantiate(Resources.Load<T>("SingletonPrefab/" + typeof(T).Name));
            }

            return _instance;
        }
    }
}

my fave

this is used to set up some DontDestroyOnLoad objects

[hard viper]

the singleton class I linked derived from monobehaviour

it's got everything you need for singletons in unity

its GetInstance() is thread-safe, can check scene for already-existing monobehaviours in the scene, and allows DontDestroyOnLoad optionally

it's just a lot better

[heady iris]

this singleton yoinks itself from the Resources folder

[hard viper]

https://bitbucket.org/EngiGamesBitbucket/howtomakethatgame/src/master/Canvas Manager/Singleton.cs

check it out. it's a very good implementation.

[heady iris]

returning null when the game is quitting is a decent idea

i ran into a similar problem when unloading a scene

the singleton object could get destroyed before something else tried to use it (to unsubscribe from events)

[hard viper]

i think I added in an oprional protected field to avoid DontDestroyOnLoad

[heady iris]

using UnityEngine;

public abstract class SingletonSO<T> : ScriptableObject where T : SingletonSO<T>
{
    private static T _instance;
    public static T Instance 
    {
        get
        {
            if (_instance == null)
            {
                _instance = Resources.Load<T>("SingletonSO" + "/" + typeof(T).Name);
            }

            return _instance;
        }
    }
}

extremely similar idea to the first one

[hard viper]

hold up something is wrong with the implementation I linked. The implementation I know has a lock for threads

[heady iris]

is accessing a unity object from anything but the main thrad ever legal

i haven't really wanted to do that before

I know that the video said that implementation wouldn't handle multithreading correctly.

[hard viper]

yeah. I'm pretty sure you need a lock

[rustic arch]

Hello everyone! Did anyone experience any issue with the camera movement after switching to new player input system? When I'm just moving with A/D around an object or corner or anything looks smooth but if a move the camera and press A/D it's becomes really jittery. I'll attach a video below if anyone had this problem. I've been spinning around it all day long 😭

[long plover]

I will get to that if I have time

[heady iris]

Are you using deltaTime to scale your mouse input, by any chance

That can cause gnarly jittering (because it's wrong)

[rustic arch]

Could the mouse_x / mouse_y cause the problem since I'm using deltaTime there?

https://pastie.io/mcyzbk.cpp

[heady iris]

Yes, that's wrong

Mouse input is an absolute amount. It's not a rate of change, like a joystick would be

Don't scale it by deltaTime.

[rustic arch]

I'll try it and get back to you, thank you!

[long plover]

I cant seem to get the player to teleport when they get close/touch the soldier. What am I missing here?

[heady iris]

You'll need to adjust your mouse sensitivity to compensate for this (cut it by a factor of 60 or something)

[rustic arch]

'right

[heady iris]

If you multiply deltaTime in, you'll wind up making small movements really small, and large movements...less small

since longer frame times mean the mouse moves further

[long plover]

@leaden ice@hard viper@fervent furnace (sorry for mass ping, just need this quickly solved 🥲 )

If unity gets stuck for that long, just kill the process and reopen it

[unborn flame]

will it damage my project?

[long plover]

@fervent furnaceIt does print out this

Seems like the player teleport line is not working correctly

[heady iris]

Nope. It could mess up the Library, but that can be completely deleted and recreated without issue

the library is full of cached files, basically

[fervent furnace]

log the return of GetPosition not the enum value

[rustic arch]

Somehow it's still not working. I've also adjusted the sensitivity

But it still does the same

[long plover]

alright, 1 sec

[heady iris]

Does it still happen if you maximize the game view?

[rustic arch]

I was thinking that the problem might be cuz i have the movement inside fixedupdate and the cam movement inside update, maybe?

[heady iris]

Ah

Yeah

[long plover]

So its correct location

    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        //Ground check
        isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
        //Reset velocity if grounded
        if (isGrounded && velocity.y < 0)
        {
            velocity.y = -2f;
        }

        // Getting the input
        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");

        // Creating the moving vector
        Vector3 move = transform.right * x + transform.forward * z; //(right - red axis, forward - blue axis)

        // Actually moving the player
        controller.Move(move * speed * Time.deltaTime);

        // check if the player can jump
        if (Input.GetButtonDown("Jump") && isGrounded)
        {
            // Going up
            velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }

        //Falling down
        velocity.y += gravity * Time.deltaTime;

        //Executing the jump
        controller.Move(velocity * Time.deltaTime);

        //Check if the player is moving
        if (LastPosition != gameObject.transform.position && isGrounded == true)
        {
            isMoving = true;
            // for later use
        }
        else
        {
            isMoving = false;
            // for later use
        }

        LastPosition = gameObject.transform.position;
    }
}

My groupmate made that

[rustic arch]

I've changed from interpolate to extrapolate, it's still jittering but not as fast as before, but still visible

[fervent furnace]

ohhh, I will try that, 1 sec

[rigid island]

https://unity.huh.how/character-controller/teleportation @long plover

[heady iris]

It's very easy to get jitter if your camera's movement and rotation happen at different intervals

I'm not sure I'd want to use a rigidbody for a first-person camera like that

[rustic arch]

is it possible to swap it to a cc and still use the new player imput system?

Absolutely.

But since you are getting the debug.log it means you are getting a response different than 0 from your php script

[upbeat raven]

btw

[rigid island]

also should not use WWW class

its deprecated

use UnityWebRequests

[upbeat raven]

i was trying but nothing changed

[knotty sun]

this has nothing to do with SQL, it's a php problem I guess

so you should be looking at the server log

[harsh coyote]

Hey, just curious if you were able to solve the issue?

[rustic arch]

I found out I'm rotating the camera and I should rotate the rigidbody instead. Idk how to do this but trying now

[harsh coyote]

Ok thanks, I'll try that too.

[harsh coyote]

I tried using Cinemachine, set Update Method to Fixed Update and it seems to be better.

[hexed pecan]

What is your rigidbody's interpolation setting?

[true blade]

would anybody be able to tell me why my script isnt detecting any collisions

using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting.Dependencies.NCalc;
using UnityEngine;

public class ScoreTrigger : MonoBehaviour
{
private ScoreCounterBlue counter;
private float Score = 0;
//public Collider colliderZone;
// Start is called before the first frame update
void Start()
{
counter = GameObject.FindGameObjectWithTag("MainCamera").GetComponent<ScoreCounterBlue>();
}

// Update is called once per frame
void Update()
{
    //counter.countScore(Score);
}

private void OnCollisionEnter(Collision Col)
{
    if (Col.gameObject.layer == 3) {
        Score++;
        Debug.Log("BoxEntered");
        counter.countScore(Score);

    }
}

private void OnCollisionExit(Collision Col)
{
    if (Col.gameObject.layer == 3)
    {
        Score--;
        Debug.Log("BoxExited");
        counter.countScore(Score);
    }
}

}

Does the other collider well have a collider?

I believe one of the Gameobjects should also have Rigidbody

[true blade]

well im trying to have a certain spot on the ground be the trigger so that has a collider ith the box set as a trigger

no rigidbody

but the gameobject im trying to detect has a rigidbody and a collider

[somber nacelle]

click the link i sent

[true blade]

im not sure what type of collision i have

its a box collider in one object with a box collider set to trigger on another

ive tried detecting with layers with tags and with my objects name that im trying to detect

nothing works so far

[somber nacelle]

have you gone through the link i shared that takes you through all of the troubleshooting steps you need to check? i'll give you a hint, it will show you what you've done wrong

[true blade]

i did and i got to the collision matrix chart but im a bit confused as to what im looking at

[somber nacelle]

scroll down to see what each thing means

[true blade]

im still a bit confused

i tried checking the kinematic box on my gameobjects im trying to detect but that just freezes them in place unless im actively moving them

[somber nacelle]

your issue isn't whether they are kinematic. you are using a trigger collider and expecting to get a collision message.

[true blade]

but when i try to use ontigger its telling me i have an incorrect signature

[somber nacelle]

because you do. again, see the link i shared

[true blade]

alright

[delicate flax]

yes, because OnTriggerEnter takes a Collider not a Collision

[true blade]

ah i see

[delicate flax]

ez to miss since they look so simmilar 😄

[true blade]

sorry im pretty new to these things and its all the little stuff that i tend to miss

[delicate flax]

and OnCollisionEnter takes a Collision

[true blade]

yeah

its all working the way i want now

thank you simex and boxfriend, probably wouldve been banging my head against a wall for a few more hours without your guys help

[dusty hedge]

I am having a bit of trouble compling for linux;

cannot execute binary file: Exec format error unity

I get that when I run the complied file. After some research I have seen it is because my unity project is suported for 64bit only, and my OS is 32bit. Is there a solution for this? I am using unity 2022.3.16f1

[heady iris]

I don't think you can make 32-bit linux builds.

[verbal gate]

Hi, is anyone free to help me go through some issues im having. I am using the new input system and using the rebindUI sample from it but the keybinds aren't being preserved across scenes

does anyone know how i can fix this or help debug it?

Hello, i have ScriptableObject X. I used to Instantiate X for creating instance of class. Now i added List<ScriptableObject> Y to X. After that in editor, i add ScriptableObjects to Y.

So if i instantiate X, do i get instances of Y objects too? or Is there any way to get instances of Y?

[heady iris]

No. The original object and the new object's lists will refer to the same objects.

You know, I'm not as confident as I thought I was 30 seconds ago. Let me go look.

[dusky pelican]

Then I need to instantiate the objects in the list separately

[heady iris]

What are you trying to accomplish here?

[dusky pelican]

I have Gun SO and GunSkin SO, so list will be List<GunSkin>.

I need to add GunSkins to Gun

Also i am trying to get instances because i use SO as pre defined datas

So i can save and load easily

Long story short, i just need to get instances of every object in list.

[heady iris]

okay, yes, it's as I expected

instantiating an object just copies over the references it has

that makes sense; otherwise instantiating an object would give it copies of things like materials

[heady iris]

are you mutating these GunSkin objects?

[dusky pelican]

Actually, i don't know really meaning of mutating but in GunSkin SO, i have fields like CurrentAmount, LevelOfSkin etc.

[heady iris]

"mutating" means to change data

so yes, you're modifying the objects

[dusky pelican]

Yes.

[heady iris]

I would suggest storing the data that changes somewhere else

GunSkin is a definition of a gun skin

something else should keep track of which gun skins you have

that completely avoids the issue

[dusky pelican]

Okay, i will try to do that way. Thank you so much!

[fallow sail]

hello, i have a basic game on google play. For production release i need to complete closed test. For closed test i need 20 volunteers. Can anybody help me to download my game to their device?

[simple egret]

This is a code channel, you may try your luck in #1180170818983051344, or on the Forums. In either case, read the posting rules as you'll need to include more information about your game than this

[tacit swan]

when im playing a timeline using PlayableDirection.Play() it seems like the music starts playing before the entire project gets compiled resulting in the timeline signals being off. Is this a problem that will be resolved if i just compile and build the game?

Whats the best (working) way to use google apis in unity. I looked at the .net client but it says unity isnt supported. for context I am trying to acsess google sheets api through http requests but oauth is needed and to my knowledge that requires google apis. let me know if this is inncorect

[hard viper]

how do I define a generic with the constraint that < is defined?

[simple egret]

Operators overloads are static, and interfaces forcing static members to be implemented is not supported by Unity

[hard viper]

unfortunate

well, is there a catch-all for T being a numeric type?

like int, float, uint, long, etc... which would have those defined?

[simple egret]

Not that I know of. Generic math and stuff like INumber<T> was added in .NET 7 or so

[hard viper]

hmmm, maybe I'll try IComparable

[simple egret]

Ah yeah there's that one, should work for most of these types

[hard viper]

yeah. i just wanted to constrain more, so I don’t think in the future to put random Icomparables into this generic

future stupid proofing

[rocky basalt]

Is there an easy way to draw a few lines between vertices without applying a bunch of LineRenderer components in the editor?

I have a few quads and I just want to be able to draw an "outline" between the four corners of each quad on demand

[twilit scaffold]

So to get the full performance out of Unity, i should learn/use DOTS and ECS? Or have they changed to some other paradigm already?

[rigid island]

whats wrong with line renderer?

[hard viper]

it’s a different workflow

[spring creek]

If you want, you can use ECS, otherwise you use MonoBehaviours (and OOP).
Data Oriented Design like ECS is more performant in many cases yes

[hard viper]

DOTS/ECS is more efficient because it is a different representation

[rocky basalt]

Would I need 4 LineRenderers for each quad though, or can I draw 4 lines using just the one?

[twilit scaffold]

Ok, thank you both

[rigid island]

ofc.. you only need 1

line renderer takes an array of points, you can make as many as you need

[hard viper]

it’s like how you can represent everything with Matrices or gameobjects. Obviously matrices will make everything fast af, but that requires you to create matrix representations. Similar thing

[twilit scaffold]

i see. Ok, i will have to see if i can even comprehend the different way of thinking then

[hard viper]

note that computational time you save may come at the cost of more time programming

you could code a game in assembly, and it would be fast as shit. but that involves coding in assembly

[twilit scaffold]

an important consideration as a single person 'team' :/ not counting my extended team (you's guys)

[hard viper]

the whole point of unity is to use the engine to save time coding

[latent latch]

ECS is worth it if you're building some large unit game like an RTS

[twilit scaffold]

I am working on a RPG, with a limited number of units on screen at the same time. Complex customizable character though, so i have to figure out how to handle the 650+ morph targets/baking

[hard viper]

then don’t fuck with ecs

you won’t need it

[twilit scaffold]

cool deal. so no benefit trying to'ECS' a bunch of trees or the like.. that is a different system entirely? (Just today starting to look at ECS)

[hard viper]

it’s a very different way of programming a game

[spring creek]

You would most likely see some benefits, but the drawbacks are going to make it not worth it for your game I believe. You can't use most components directly (like, notably, the animator) without creating a workaround or buying an asset

[twilit scaffold]

I am coming from the Unreal way of doing things, so a lot of this optimization was automatic there. completely different here

[hard viper]

ECS excels at processing a huge number of separate things at once

[twilit scaffold]

Ah. Ok. That definitely tips the scales

[hard viper]

imagine trying to process a simulation for a real gas, for example

where you have 10 million particles, all colliding with each other

you will not make it with 10 million dynamic rigid bodies

[twilit scaffold]

i see. that makes sense. So i should just depend on the Unity 'standard' way for the usual things like Instancing multiple trees/meshes and not even bother considering it for that then

[hard viper]

that is how I would start

or start with godot if you know nothing about unity

godot is growing, while unity is shrinking

[twilit scaffold]

Nah, godot cannot even handle my Character due to the massive initial size because of the Shape Keys

Ya think? hmm. i was hoping Unity was about to do a big push forward

[hard viper]

last year’s big announcement screwed up unity’s upward trajectory. lots of people jumping ship to godot

[worthy tinsel]

Familiarize yourself with basic building blocks of ECS: Burst compiler and Job system. Those can be used independently and can provide substantial benefits without switching to full DOTS

[twilit scaffold]

sounds good, thanks

[hard viper]

that said, Godot isn’t fully ready, but being a part of the community as it grows will give you a big advantage if you stay with them

whereas Unity is very established

and most new features are experimental and half-baked

[rigid island]

its making good progress but will actually catchup to unity any time soon. don't think so

[twilit scaffold]

coming from Unreal, i am used to half baked, and flat out broken in some cases😄

[rigid island]

I hate that part of unity
puts an amazing feature and then just kinda abandons it

[hard viper]

it will take time for godot to catch up. but they will steadily grow

and being open source will lead to far fewer “sealed class fuck you lmao” moments

[twilit scaffold]

indeed

[hard viper]

and no “i have no idea what this does because this code injects proprietary C++ code” moments

[rigid island]

the terrain tools looks better than the unity one somehow 😮

[latent latch]

unity terrain tools haven't been updated since 2012

[hard viper]

unity terrain tools are ass

[rigid island]

exactly

[latent latch]

roblox has a better terrain editor

and no one uses that

[hard viper]

what has driven me nuts is the whole physics2D being injected

[twilit scaffold]

That does bother me, but after working with Unreal for years, i realized that while it can do 'everything', the amount of time it takes to do basic things is not feasible for an individual. On the other side, Unity seems to have a faster development cycle for individuals. and Godot, while deserving of a big thumbs up, is just not technologically on par, yet

[latent latch]

with that being said, terrain editor is still pretty good at optimization and culling

[hard viper]

want to see what effectors do? gfy
want to know how joints work? gfy
want to modify physics simulation? gfy
want to actually make custom parametrized colliders? gfy, and CustomCollider2D wasn’t even properly tested lol

[quartz folio]

Things will change a lot in the coming years; it's been a while coming. When they transition to modern .NET it will take huge leaps

[twilit scaffold]

Awesome! looking forward to it

[hard viper]

i’m still holding my breath for full C# v9 support

[quartz folio]

it'll come with the transition

and then you'll have C# 13 by that point 😄

[hard viper]

yeah… given godot is building their C# compatibility now, I expect the first version they support to be C#13+

anyway, point being, it’s worth checking out godot as it grows if you have no experience with unity

[latent latch]

think of how many lines of code ill be saving with struct initializers

[hard viper]

and records

[quartz folio]

primary constructors, namespaces without scopes

regex and json source generation

nuget...

raw string literals 🤤

string interpolation that doesn't allocate at the point it's declared

a non-shit GC

[rigid island]

doesnt box2D have documentation or you mean specifically unity components and how they're implemeneted

[hard viper]

unity interfaces into box2D. You can see how box2D works. You can see how unity works within C#. But you can’t see the critical junction in C++ where unity actually works with box2D

[rigid island]

ah yeah 😢

[hard viper]

as in, the actually important part is invisible and non-editable

which is part of why i built my own physics engine from scratch

i needed to modify some critical things where Unity did not allow me

[covert shard]

hey there, i am having a weird issue that i hope someone here has been through before. for some reason just moving the unity scene is causing my high end computer to reach 95 cpu and high gpu usage and as soon as i stop everything comes back to normal. is there a setting that i need to turn on or off that i should know about?

[spring creek]

Profile it and see what is happening

[covert shard]

how do i profile the scene? i though i could only profile the game running

[calm talon]

I have a Light 2D component on a tiled sprite and I'm wondering how I can find the corners of said sprite to align the light's shape to so I don't have to manually resize it

[covert shard]

nvm found it

[hard viper]

i don't think sprites really have corners, unless you read the pixels in it

and then actually search for specific patterns etc

[calm talon]

well I do have a collider on it

[hard viper]

then use the collider shape

call GetShapes on the collider, and sift through the shapes.

[calm talon]

alright

[hard viper]

also, graphics and hitboxes don't mix well

[calm talon]

I tried using a polygon collider's path but that didn't work out lol

[calm talon]

it's lava

[hard viper]

is it a big complex shape?

[calm talon]

nope

s q u a r e

[hard viper]

bruh, just calculate it

[covert shard]

welp windows shift s isnt working

but is turns out that the main thing that has spiked

[spring creek]

Open snip and sketch once
Should work after that

[covert shard]

i did that that didnt help but that should be a big problem just a restart from my computer, but the main thing that spiked in the unity editor is just application.idle

what does that mean?

ama restart until i get a response ill be back shortly

im back

damn, after i restarted the performance only is affecting the gpu now the cpu only increases by like 5%

[foggy sentinel]

does someone know how I would fix this. I dont want the player to be able to float like this on the edge but If I shrink the width of the collider it will be smaller then the body.

[rigid island]

this is a tricky problem to solve

a raycast can help you check if you're not grounded then push the player slightly off

[foggy sentinel]

Ok Il try that thank you

[cosmic rain]

Maybe use a capsule collider instead?

Then you'd naturally slide off if the center is out the edge.

[foggy plaza]

It's too much code, but I changed it and put the management of the values in a component in the gamemanager. It seems that ScriptableObjects are "baked" in the build so the values are not really editable on runtime, it's just confusing the Editor has a completely different behaviour.

[cosmic rain]

They are editable as any other object. They just don't save between the sessions like they do in the editor.

That's why if you save them to a file as json to load later it should be working.

If it doesn't there's something wrong with your code, which is why I mentioned that we need more details.

[foggy plaza]

I did that, and I debugged the messages, the values were saving and loading correctly in the json. The code worked in the Editor but not in the Build. I am using 2022.1.18f1

But I like what I did now, so I think I am just gonna refrain from saving data to ScriptableObjects

[indigo hound]

Hey there, so I've been making a game with powerups, and for each 'powerup state' I've made a scriptable object. In it, I have a 'HandleMovement' method, where the necessary stuff is done to make him move. This method is then called in FixedUpdate in my PlayerController script. Sadly, the velocity value doesnt add up like it should, so my player just stands still and cant move around. When I set the HandleMovement method directly (without using SO's) in the PlayerController script, it does work. Through the Scriptable object though, it doesnt.

Below you can find the (simplified) HandleMovement method, and the place where it's called in my PlayerController script. Could anyone help me with this, or explain why it doesn't work?

HandleMovement():
velocity.x += inputDir * physicsConstants.walkAccel;

PlayerController, FixedUpdate();
playerPowerupStateController.GetActivePlayerPowerupState().HandleMovement(controller, directionalInput, velocity, this, isDucking, isSkidding, isRunning);
controller.Move(velocity * Time.fixedDeltaTime);

[hard viper]

how does your SO encode the information for which function to use

[indigo hound]

Sorry I dont understand I think, what do you mean?

[hard viper]

if I understand, you have one SO for normal mario, and one SO for frog mario which would have different controls in water, or something like that

[indigo hound]

Yeah

[hard viper]

and each SO is a different asset of the same type?

[indigo hound]

No, so let's say we have FrogMario, he would have a different script which derives from a general PowerUpState SO, which can then override the HandleMovement() method so it fits the frog behaviour

[hard viper]

ok, so this sounds like a case to use an interface or abstract class, potentially

eg IPlayerMovement

then your powerup SO (eg an SO with info about a mushroom, with sprite and state etc) can take a TypeReference to a type that implements IPlayerMovement

class typereferences in a plugin that lets you serialize a reference to a specific type, btw

then I would define methods:
public interface IPlayerMovement {
public bool AllowJump {get;}
public void HandleJump();
public void HandleMove();
}
etc.

it’s what you’re doing now, but with an interface (or abstract class) instead of SOs

[indigo hound]

Hmm I see yeah, I might have to try it. And is there any reason why the HandleMovement() method doesnt work through the SO? While it does work if I place it directly into my PlayerController script?

[hard viper]

you could probably use SOs, but it is a weird use case because you might want to instance to hold variables in future, and SOs are weirdly persistent

like if my SO has bool isGrounded, which it uses to figure out what to do in HandleMovement(), you’re going to see some weird stuff happening with respect to starting with old values

which you can totally overcome, but is an additional pain point which is avoided with non-SO solutions

if I had to guess, you are storing fields in your SO which are used for calculation?

or a reference to the rigidbody, or other things which only exist in the scene?

[indigo hound]

Alright thx! My SO has data for the Animator it has to play, base -and crouchsize, ... so i can set it whenever a new powerup is picked up. It doesnt store the rigidbody though or speedvalues, those are stored in a seperate class PhysicsConstants

[hard viper]

I see. Also, I believe what you are doing is called the Strategy Pattern. That might help you find resources on different ways to implement it.

[indigo hound]

Alright that could be helpful thx

[hard viper]

good luck

[indigo hound]

Thanks!

[hard viper]

btw: https://openupm.com/packages/com.solidalloy.type-references/?subPage=readme
This plugin is very useful if you need to serialize a reference to a class.

in your case, it would be something like:

public class FrogMovement : PlayerMovementStrategy {…}

public class Powerup : ScriptableObject {
[field: TypeExtends(typeof(PlayerMovementStrategy)), SerializeField] public TypeReference playerMovementType;
// Animator settings…
}```

this defines the powerup’s SO as having whatever settings are completely immutable and locked in. Then TypeReference lets you instantiate whatever powerup movement behaviour you need based on the SO. Since the PlayerMovementStrategy isn’t an SO, you can create, nuke, reset etc it at will, without worrying about old values.

[swift falcon]

Hey guys

I have a problem

Where my damage prefab is not showing at the objcet being damaged

Here is how i instantiate:

[indigo hound]

Thanks a lot!

[swift falcon]

The prefab is not spawning at the damaged object

I don't even use localPosition

What's the error here

[rigid island]

where is it spawning

[swift falcon]

I'll show you a screen recording

Cause it's kinda hard lol to just show it

[swift falcon]

Navarone

It's a little laggy, I apologise

But here you go

[rigid island]

all good

[swift falcon]

I don't know how to fix this

OBS bro

[rigid island]

so its not appearing at all ?

[swift falcon]

No

It is

Let me tell you the timestamp sorry

At around 0:18

It's the yellow "1"

[rigid island]

oh ok and which object has the script you posted

[swift falcon]

Here

Butter guy

[rigid island]

and the prefab for text

also maybe try transform.localPosition for Instantiate param

Im thinking it might be spawning behind the sprite as well , so maybe an offset would help. along with rotation

ie make the rotation look at camera

[swift falcon]

oh?

hang on

Popup text

[rigid island]

im thinking rotation / position

[swift falcon]

how do i fix that

lol

[rigid island]

hmm first add localPosition and add offset, because position spawns it at center of npc since thats where ur pivot is

rotation wise you could do LookRotation from camera

[swift falcon]

why local position?

wont that mess it up

[rigid island]

when you have a child object, localPosition will give you the position relative to parent

[swift falcon]

exactly

let's see

[swift falcon]

the term for this is sprite billboarding right?

or is it different

[rigid island]

yeah sort of

[swift falcon]

alright

[rigid island]

you could also put Debug.Break after Instantiate, and it will pause the simulation so you can see where its spawning exactly

[swift falcon]

yeah navarone

it's not working

because i dont move the sprite

i move the parent

which means localPosition can't change

it'll stay in the same place

let me make it debug.log transform.rotation

[rigid island]

try this one first
#archived-code-general message

[swift falcon]

alright

[rigid island]

you will see it inside the hierarchy and press F to focus on it

[swift falcon]

aight

thanks for telling me it exists

it's helpful

AIght

@rigid island

[rigid island]

this one doesnt help much, show the one in the scene while game is paused

like where is it inside the scene view

[swift falcon]

this is the butter parent

sure

OH

Do you reckon its the width of the text box?!

Oops

💀

It is

[rigid island]

lol

[swift falcon]

lol

thank u

at this point you belong in the game credits 💀

[rigid island]

you're welcome! glad its sorted

[swift falcon]

:)

lol 1 more thing @rigid island concerning this game if you could help

i might as well as right now

[rigid island]

sure

[swift falcon]

when my player rigidbody hits one of the butter guys, he goes flying

same with when i make the terrain a little bit elevated

increasing mass doesn't just help

because theni n eed to increasethe speed a ton

[rigid island]

are you using physics to move?

[naive heron]

anyone know how i can get the rotation to look more natural and less forced?
code:
rayHit.rigidbody.AddForceAtPosition(direction * 10, rayHit.point, ForceMode.Impulse);
rayHit.rigidbody.AddTorque(Vector3.Cross(Vector3.up, direction) * 10, ForceMode.Impulse);

[swift falcon]

yeah

[rigid island]

you could potentially Lock all constraints on rigidbody

[swift falcon]

huh?

really?

[rigid island]

also inputs should be grabbed in Update. rigidbody in FixedUpdate

[swift falcon]

ah

sure let me try

freeze position?

[rigid island]

yeah

[swift falcon]

sure

[rigid island]

anything you dont want moved by other colliders

[swift falcon]

oh

[rigid island]

since you're moving it with code constraints will have no effect on your code but help lock in rigidbody

[swift falcon]

i didn't know that

oops

it's not letting me move

💀

[rigid island]

oh right maybe only kinematics it works

maybe try to unlock X and Z only

[swift falcon]

but then how do i make him jump in the future

[rigid island]

maybe just use a character controller so your player dont go flying on collisions?

[swift falcon]

sure

[rigid island]

change rb.velocity to character Controller.Move(moveDir * Time.deltaTime * speed)

[swift falcon]

Aight

Thanks man!

If I have any more problems I'll write them down here

But you helped a lot

🫡

[rigid island]

good luck!

[swift falcon]

thanks!

this game is gonna look goooood

[keen imp]

hi is there someone here who would like to help me on the Generics or do i need to go in the beginner channel ?

[spring creek]

You mean generics the code term with a specific meaning? Or generic like the english word?

[keen imp]

no generic like the code term

[spring creek]

Ok, then just ask.

[keen imp]

might be abit long i will write it in a txt and write here in one blow (sorry again 😭 i'm new)

So I'm trying to implement a A* pathfinding algorithm.
I have created a grid class where i can put a generics in the constructor to put a custom type for example a PathNode class that i made.
So when i try to create my object in my script here is my A* script,my grid script and my nodes script

public class Astar
{
    private Grid<Node> grid;

    public Astar(int width, int height)
    {
        grid = new Grid<Node>(width, height, 5f, Vector3.zero, (Grid<Node> g, int x, int y) => new Node(g, x, y));
    }

    public class Node
    {
        private float Gcost,Hcost,Fcost;

i get an error, that say incompatible anonymous function signature (i'm on RiderIDE )

i don't really understand what is an anonymous function beside my research

[heady iris]

An anonymous function is a function that has no name.

You declare an anonymous function by using the => operator

The only anonymous function I see in your code is this

(Grid<Node> g, int x, int y) => new Node(g, x, y)

This is a three-argument function.

Grid's constructor takes a Func<TGridObject> as the last parameter.

That's the type for a function that takes 0 arguments and returns a TGridObject

These are incompatible.

[keen imp]

oh okay so if i make a function that create 1 node with 3 args it won't work then but it will not be anonymous at least ?

[heady iris]

I think you need to rewrite the Grid constructor.

It sounds to me like you want to be able to pass the x/y coordinates to the "create grid object" method

as well as the grid itself

But Func<TGridObject> doesn't allow for any arguments.

What does allow for arguments is Func<Grid<TGridObject>, int, int, TGridObject>

This is a three-argument function that returns a TGridObject

If you switched the constructor to take that, and then passed those arguments on this line...

gridArray[x, y] = creategridobject();

...it would work

[keen imp]

okay i need to work back on my grid then thank you 👍 back to work

[untold quail]

So my terrain is made of closed spirte shapes. Using that with Unity's 2d lighting system though causes the shadows to cast incorrectly around a rectangle outlining the terrain shape. Is there anyway I can fix the shadows without manually setting each point of the shape of the shadow myself? Or, an alternative to using sprite shapes for my terrain in general that still gives me the freedom to create levels not on a grid

[crude mortar]

You could probably make your own script to set the shadow points to the vertices of the sprite shape in edit mode, probably via some button in the inspector or something.

I believe that all the necessary API exists to do so

[untold quail]

Sounds like a fun challenge, I'll try my best!

thank you! :0

[indigo hound]

Hey, I tried this out but get an error when using the 'TypeExtends' as it says it doesnt exist. Any idea what I did wrong here?

[indigo hound]

I changed it to 'Inherits', but afterwards when I try to call the methods from the PlayerMovementStrategy class, it can't find the method due to this error:
Any idea how to fix this? 🙂

[quartz folio]

Doesn't this thing serialize types, not instances of types?

[indigo hound]

Not sure I'm not too familiar with it yet

[eternal tusk]

how to shorten the stretching distance when using the "Configurable Joint"?

[frosty snow]

void Awake() {
    Collider[] colliders = GetComponentsInChildren<Collider>();

i think i got my ragdoll to work o.o

[eager steppe]

How do I make numbers line up in my leaderboards?

It took me a bit of reading to see this isn't a bug, but rather my score simply just has less numbers that require a lot of space

[somber nacelle]

#📲┃ui-ux
but also using a monospace font

[eager steppe]

oh mb

ty

[upper pilot]

CombatActions = CombatActions.OrderByDescending(i => i.Move.MoveSO.Priority).ThenBy(i => i.Character.Attributes.Speed).ToList();

Doess the .ThenBy sort in descending order or ascending in the above example?

[somber nacelle]

considering there is a separate ThenByDescending, i'd assume it sorts in ascending order

[upper pilot]

makes sense

[karmic brook]

Yeah it sorts in ascending order on default

[upper pilot]

Ah there is ThenByDescending 😄

[upper pilot]

Error:

NullReferenceException: Object reference not set to an instance of an object

When debugging the above line everything seems fine, until `.ToList) I think

So I am getting Speed of character

This line:

        CombatActions = CombatActions.OrderByDescending(i => i.Move.MoveSO.Priority).ThenByDescending(i => i.Character.Attributes.Speed).ToList();

[fervent furnace]

dont use (one line) lambda expression and debug inside?

[upper pilot]

How can I change this to multi line?

The idea is to sort moves by their priority, but if the priority is same then by character speed

[fervent furnace]

()=>{statements; return value;}

[upper pilot]

i.e. Move priority -1 and -1 would be sorted by character.speed

[fervent furnace]

btw you can have a custom comparator then just inplace sort

[upper pilot]

I dont know how to make it work with what I need other than making a list for each priority then combine those sorted lists.

FireBall: Priority 1, CharacterSpeed: 10
IceBall: Priority 1, CharacterSpeed: 5
MetalBall: Priority 2, CharacterSpeed: 1

Priority: MetalBall, FireBall, IceBall

[latent latch]

just gotta code your whole project on one lambda line

[fervent furnace]

i know, Icomparator can sort the list in any order you like, since you have full control on the return value

public int cmp(type a,type b){
  if(a.priority==b.priority){
    return a.speed-b.speed;
  }
  return a.priority-b.priority;
}

[upper pilot]

Does it work with negative values?

Because Priority can be between -3 and 3

[fervent furnace]

-3-3 is -6

usually cmps return negative if the first one "less" than second one

[upper pilot]

Found the error with my code, for w/e reason it was setting Character to null.
If the previous solution works then I'd keep it

[swift falcon]

For some reason, my sprite is not showing on the screen in unity 2d. Any ideas?

im talking about "player"

[somber nacelle]

Not a code issue. It's too close to the camera.

[swift falcon]

thought about that

how could I fix

[somber nacelle]

Put your camera at -10 on the z axis and everything else at or above 0

[swift falcon]

all axis?

[somber nacelle]

Oh actually it's not too close to the camera, it's nowhere near it

It looks like it's on your canvas for whatever reason

[knotty sun]

Why do you have non UI objects as children of the canvas?

[swift falcon]

got it out of the canvas

still nothing

oh got it

[somber nacelle]

Did you also move it to where the camera is actually at?

[swift falcon]

camera is that small rectangle at bottom-left

imma just make my sprite an image

[somber nacelle]

Yes. Notice how you've made the player's scale 50x50. It's huge

Your ground shouldn't be on the canvas either and if you go trying to use UI objects for this you're gonna have a bad time

[swift falcon]

alright

[upper pilot]

    public int Defense
    {
        get { return (int)(((float)CharacterSO.BaseDefense + (float)_Defense) * (Character.HasStatus(StatusEffect.Restrained) ? 0.5f : 1f)); }
        internal set { _Defense = value; }
    }

Looking for recommendations.
Should I store defense/base defense as floats to make the above cleaner or is there a better way?
