Wouldn't it add torque every frame if I were to put it into update?

inner relic
#

should I just refactor the code, or is there something obvious that I'm missing.

dusk apex
static crown
#

That's probably a better way to do it than what I've been doing, thank you!

inner relic
#

someone else had the same problem and they never got it fixed notlikethis

fluid lily
#

This didn't work. If the Inspector is open in debug mode and I press the UI button it throws houndreds of the errors...

cosmic rain
#

What kind of events are you subscribing to? Are you sure they fire every frame?

inner relic
#

For example: I'm trying to implement an interaction interface

#

When I press the key for the door, it opens and closes like 20 times

cosmic rain
#

Well, we'll need to see the code. Otherwise it's just assumptions.

inner relic
#

Trying to press the key for only 1 frame is essentially impossible

inner relic
#

I'll just refactor it

#

cause although it won't be pretty

#

I can just use the method i've used for other first person controllers I've made

#

and just use that input handling

What do you need the inspector in debug mode for

fluid lily
# leaden ice What do you need the inspector in debug mode for

The button's background image only works once, and then once I click it the background stays on the default background. Also then once I click anywhere else the button background works again. I am not messing with the the button on script side either. I was trying to see if one of the private variable states was only switching back once I click again.

#

Like the hover over highlight stops and no press button, I can still press the button though.

Hey all! Trying to write code that adds all images (just jpgs and pngs) from the player's pc to a list that can then be drawn from in a random selection function. I know it needs to use stuff like Environment.GetFolderPath(Environment.SpecialFolder.Desktop) but don't know how to piece it all together

leaden ice
torn eagle
#

Oh no I meant more so just places where images commonly are

#

I'm only scanning desktop, downloads, documents, and the images folder

dim spindle
#

Uhm personally as a player i would find this kinda invasive

leaden ice
#

Even that can potentially take... well forever basically, depending on how many files they have, how slow their drives are etc.

You'll want to do the scanning in a background thread for it to be reasonable

#

Are you just making a virus???

#

Wdym

torn eagle
#

It's a file manipulation game

dim spindle
#

Use an in game file system

potent sleet
dim spindle
#

Inb4 "file manipulation game" just means manipulating the files so you can charge ransom for them

leaden ice
#

I'm just going to stay very far away from your game though

dim spindle
#

Yeah

#

Im gonna agree with that second point

torn eagle
#

Can't blame ya for not trusting me but I promise it's just a cute lil game about generating flowers out of player images

leaden ice
#

It always starts that way...

dim spindle
#

Also uh

#

It took you a bit to come up with that?

#

And reading the players every image isnt great anyways

#

Imagine you read the sussy folder on their desktop

leaden ice
#

It's going to be super slow and yes also this ^

#

Does anyone know what the non-"prefab edition" of navmesh is, and how I could use it?

image.png
#

I don't recall using any navmesh prefabs

dim spindle
#

Uh more context would be nice

#

Where is this menu showing up from

quartz folio
unreal temple
#

Maybe it's coming from that library.

#

My understanding was that this dialogue is from Unity core

quartz folio
#

Why are you not using the ai package?

unreal temple
#

The one you mentioned?

quartz folio
#

Yes

unreal temple
#

Because it doesn't support 2D colliders

#

Or, at least, it didn't when I first set up navigation.

#

But I'm still using NavMesh, which is (confusingly) not part of that package.

#

My best guess is that "prefab edition" means non-DOTS, and that there's a DOTS package that will allow you to use the same NavMesh object without GameObjects.

quartz folio
#

My guess would be it means you're in prefab mode or something

unreal temple
#

Ah, yes yes. I am editing a prefab hahaha

#

"prefab edition" wtf is that wording

#

Must be a typo on "prefab editor"

#

Oh, "edition" as in "the act of editing"?

quartz folio
#

🤷

#

No idea why they've called it edition, but I do imagine it's just a mistake

torn eagle
#

Can anybody help troubleshoot this for me? It seems to just set my texture to be black

            for (int i = 0; i < texture.width; i++)
            {
                for (int j = 0; j < texture.height; j++)
                {
                    float xPos = i / texture.width;
                    float yPos = j / texture.height;
                    float alpha = Random.Range(0f, 1f);

                    Color color = new Color(xPos, yPos, 0f, alpha);

                    texture.SetPixel(i, j, color);
                }
            }```
quartz folio
#

Also, you are doing integer division

#

you should be casting one side of the division (the denominator is most common) to a float

torn eagle
#

Ah I see thank you!!

haughty badger
#

is it possible to change the 'CurrentRunSaveData' class reference for a string that's being defined elsewhere in the code?

image.png
#

essentially I want to use the string to define a class reference

cosmic rain
#

That's metaprogramming. It's complicated and not recommended.

haughty badger
#

hm ok

haughty badger

which is probably better practice anyway

Imo, this constructor for this class is pretty unwieldly. Is there a better way to write this, or is this just the way it's supposed to be?

public class Tool : Item
{
    float rockStrength;
    float sedimentStrength;
    float organicsStrength;
    float entityStrength;

    public Tool(float rockStrength, float sedimentStrength, float organicsStrength, float entityStrength, int id, int amount, int maxAmount) : base(id, amount, maxAmount)
    {
        this.rockStrength = rockStrength;
        this.sedimentStrength = sedimentStrength;
        this.organicsStrength = organicsStrength;
        this.entityStrength = entityStrength;
    }
}```

quick question, How to run export unity's project on Mac M1 ? I've tried but Xcode return files .dylib and i didn't know how to run it on Mac.

remote wasp
#

Hey, so I'm working on a pet project which start to get relatively significant. Everything works well except one thing, I have a METRIC TON of spaghetti code right now. 🍝 for instance on my character, I have a character controller to handle its movement / rotation, an animator controller to handle animation changes, an AI script to handle a FSM for its AI. Pretty organized you'd say, but still, everything is interlaced, each script has references to the others, and they all call functions from one another. It gets more messy now that I integrated some controller and AI logic from animation events. And this is just for my character, my weapon system is also messy and others as well.
Do you guys have any good resources about how to organise the code, and how to architect the project well for it to be scalable without having too much pasta?

tepid river
#

if you already go the length to input a data object, i wouldnt use dictionary, to easy to mess up the initilaization. do a proper object with fields, that way the compiler will slap you if you mess it up

lethal rivet
#

Could you elaborate a bit on custom data object?

tepid river
#

basically a class that encapsulates the data you need.
class ToolProperties {
float rockStrength;
...
}

#

its essentially just a statically typed dictionary

real anvil
# lethal rivet Could you elaborate a bit on custom data object? 
struct ToolStrength
{
  public float RockStrength { get; set;}
  public float SedimentStrength { get; set; }
  public float OrganicsStrength { get; set; }
  public float EntityStrength { get; set; }
}

public class Tool : Item
{
  private ToolStrength _toolStrength;

  public Tool(ToolStrength strength)
  {
    _toolStrength = strength;
  }
  //...
}
tepid river
#

right, struct is even better 👍

real anvil
#

Record struct if you wanna get even fancier :^)

Though I think Unity doesn't support them (yet)

#

guys i created a camera script that moves the camera to the average position of the player and the mouse

#

to make the top down feel more active

#

but that made the player movement laggy

#

here is the function where i update the camera position

void UpdateCamera(){
        Vector2 myPos = (transform.position + c.ScreenToWorldPoint(Input.mousePosition)) / 2;
        //new Vector3(myPos.x, myPos.y, -10)
        c.transform.position = Vector3.Lerp(c.transform.position, new Vector3(myPos.x, myPos.y, -10), Time.deltaTime * 10);
        
}
# 
    void Move(){
        rb.velocity = dir.normalized * speed;
    }

i am trying to set a GO on 0,0,0 position, this should place it on top of the parent. but it gets placed on 0,0,0 in the scene. How can i make my GO get on 0,0,0 in its parents 'enviroment'

thin aurora
#

Because AFAIK setting it to 0 would put it at the center relative to the parent

thick plume
#

random number that is 0,0,0 in global

thick plume
thin aurora

As a child

thick plume
#

it is a child

#

its not a parent

#

and i am trying to modify the child position

thin aurora
#

Then you should modify transform.localPosition probably

#

ill try

thin aurora

(I honestly didn't even know there was a whole different method for that)

stoic dagger
#

General question: in a case like this one, if the duration variable is global and it never actually changed value, is there any point in feeding it to a function? (this case that coroutine)
As I said, its global, value set in start, and never changes value.

image.png
cosmic rain
thin aurora
#

But no, not much difference if you're confident you won't change it.

stoic dagger
#

I can see how that may be efficient, but with this one is a somewhat short Coroutine (13 lines) and it will be on maximum 2 instances simultaneously, still, for the sake of a good habit I think I will make a separate script with my function and place it on my objects.

#

Thanks u both

#

I also think this might solve a problem which i encounter sometimes, when i sometimes restart my project my scripts reset their variables to null values and I dont get why, so I started giving the values in the start function to be sure
Instead of having a separate script for the function which is called from the main script of my object I think I can also put everything in one script and have my variables set using a switch statement on the name of the object

hey,
is it possible to make a public list on the editor without the (+ and -) buttons ?

vagrant blade
#

For what purpose? So it cannot be modified? There is no built in way to do that.

You can download something like Odin inspector or Naughty Attributes which give you the option of a [ReadOnly] attribute.

quartz folio
#

Property drawers apply to collection elements, not the collection itself so that will not work

vagrant blade
#

Really huh. Well then 🏃💨

#

I found a bug yesterday

#

I think list get corrupted after deleting an item of it on the editor (inspector)

I have a custom class the holds info of the scene objects , its NAME , COunt in the scene and GUID

once i delete one of the items from the list on the inspector and try to load it again the list get corrupted
i looped through it , the name is correct , the count is correct but the GUID of all item became " 0000000000000000000000000" what is going on ?
I think I ran into a bug this time...

any ideas?

I dont think they care about those tickets at all 😄

but thanks for ur suggestion , i might report it anyway , I was just hoping that the problem is much simpler than that or i messed up or something.

is it like ReorderableList<T> ?

Bugs would only be relative to native implementations. Assuming you aren't modifying the collection and inspector serialization process, the elements should not change.

i have two buttons in the inspector , 1 collect the items with debug read the items that just added to the list to make sure that it was collected successfully , which it does.
and another just reads the list.

when I press the read list button before modifying the list .. everything is great and normal , i can read every item in the loop correctly.
but if I modified the list .... some references became NULL and values like GUID became "000000000000000000"

#

all this is happening in Editor mode ,not the play mode , so I dont think anything has changed because nothing is running

quartz folio
#

upload some code so we can see if something is wrong

dusk apex
#

Modifying the list will make the one your read button refers to not the same as what's modified - likely the issue.

#

Make certain to reacquire the list from the component on change/validation; basically, if there's a cache, it'll not represent the new list (assuming you've got a cache or internal reference to the collection rather than acquiring it every read)

solemn raven
stoic dagger
solemn raven
#

I think i found a way around it though
in the same function as im adding items to the list I've also added items to _tempList which is not being modifed
then when I modify the original list ... original list gets corrupted but _templist is not.
that is my current way around

the primary argument i get is when you have long names and stuff

@quartz folio that is exactly what is going on but ofc I had to havely simplify it

        org._tempList.Clear();

        foreach(GameObject GO in org.prefabs)
        {
                
        CustomClass C = default;
        c.guid = GetGUID(GO);
        org.prefabs.add(c);
        org._tempList.add(C);

         int index = org.prefabs.IndexOf(C);
                 CustomClass _SavedGUID = org.prefabs[index];
        Debug.Log($"GUID:{C.guid}");
    }
    
     }

    
 public void LoadGUID()

        {
        Debug.Log($"GUID:{C.guid}");
    }
}
quartz folio
solemn raven
#

the whole issue is when I remove one of the items on the list via inspector , then try to read it again , all GUID gets corrupted and I have some other refrences in the class turns into NULL

#

the way around is to have 2 lists

quartz folio
#

I don't see where you're informing the editor you've dirtied these objects, do you call Undo or use SerializedObjects anywhere?

solemn raven
quartz folio

Then you cannot expect any changes to persist

@quartz folio ugh, why doesSceneManager.LoadSceneAsync(...); take a scene of type string, whereas SceneManager.SetActiveScene(); takes a scene of type Scene

Mmm but you can get a type Scene by build index which isn't a loaded scene

It almost certainly is a loaded scene

Fair enough. I also just found SceneManager.GetSceneByName(string scene); which does the trick without fussing around

well what does the (-) do ? does it "dirtied." ? ... I think it does otherwise the changes shouldnt have been made at all.
but even if it does , why does it courropt some of the refrences and not all of them , i have a string variable in there that stays untouched even after everything is either null or curropted , I know that by looping through the whole list and print its properties ... the name is fine

#

but guid and other refs are nulled out

#

im gonna use the trick i figured out for now and hopfully someone would fix it in newer versions ?

quartz folio
#

Changes can be made, they are just transient, and if you pull from the serialized data you only get what was saved there previously

nimble kernel
#

AAAHH I should have been setting the active scene to the world scene this whole time. Now when I load into the game scene it uses the correct lighting settings from the game scene rather than continuing to use the lighting settings from the main menu

I need some assistance on my wall jump, I don't understand why it does, teleport me to somewhere else,

heres the code

private Vector2 wallJumpingPower = new Vector2(2f, 2f); 
    private void WallJump()
    {
        //Si on glisse sur le mur
        if (isWallSliding)
        {
            isWallJumping = false;
            //Méthode pour changer l'angle du Player (sprite.flipX)
            wallJumpingDirection = -transform.localScale.x;
            wallJumpingCounter = wallJumpingTime;

            CancelInvoke(nameof(StopWallJumping));
        }
        else
        {
            //si C'est false:Diminuer le compteur
            wallJumpingCounter -= Time.deltaTime;
        }
        //Si le compteur est actif 
        if (Input.GetButtonDown("Jump") && wallJumpingCounter > 0f)
        {
            isWallJumping = true;
            rb.velocity = new Vector2(wallJumpingDirection * wallJumpingPower.x, wallJumpingPower.y);
            //Empêcher de sauter plusieurs fois
            wallJumpingCounter = 0f;
            //Changer la direction du Player (Flip)
            if (transform.localScale.x != wallJumpingDirection)
            {
                isFacingRight = !isFacingRight;
                //Vector3 localScale = transform.localScale;
                //localScale.x *= -1f;
                //transform.localScale = localScale;
                transform.Rotate(0f, 180f, 0f);
            }
            //Appelé une fonction avec un délai
            Invoke(nameof(StopWallJumping), wallJumpingDuration);

            transform.Rotate(0f, 180f, 0f);
        }

Heya, I have been stuck on a weird way of movement for ship simulation game. Little bit of background information: this VR ship simulation has been a ongoing project that has been passed down between students. The last student that worked on it wanted to give the ship movement but the simulation is also multiplayer (the student before that implemented Mirror to achieve this). The student got the ship moving by moving the world instead of the ship (to not have to move players and the ship and avoiding major syncing problems). Only problem is that the world only moves correct when you do not “rotate the ship”. I got rotation working by rotation the world around the ship, but I have no idea how I can combine rotation with movement, to make the ship move in arches instead of spinning in a straight line. Does anyone have an idea how I can achieve this?

force is like 2f each, shouldnt be the problem

(my normal jump is like 20f)

You can always try changing it, or any value for that matter

Considering the velocity change is like the only relevant thing here

Hey,
is it possible to make Unity Reorderable List collapsable like any regular List<T> or Array in the inspector ?

why is everything in 1 file

i just want to know what isnt working

It's working

tribal plinth
#

well

golden vessel
#

I want to know what I'm hovering

tribal plinth
#

where you want to get the name

#

thats what i meant

golden vessel
#

I didn't implement the interfaces in the selectable class, but in each inheriting class

thin aurora
golden vessel
#

I mean if your answer is to debug.log(this) in OnPointerEnter, I could have guessed

solemn raven
#

because List<T> has it

thin aurora
#

But I mean if it ends up not actually being available, you can make it yourself.

#

And if you can't make it for that type because it already exists, you can also inherit a custom type from it

I'm running into issues when trying to make a network list of a class that includes nullable types. I get the error: The type 'Character' must be a non-nullable value type, along with all fields at any level of nesting, in order to use it as parameter 'T' in the generic type or method 'NetworkList<T>', which obviously means that I can't include nullable types in my list. So, what is the best workaround for this?

Thanks for the help

marble halo
#

I have this issue where my character controller kinda gets stuck on edges

Screenshot_365.png
#

I say kinda because if you move away you fall off

#

not sure how to fix this issue

ripe igloo
#

You're using gravity right?

marble halo
#

yes

ripe igloo
#

How did you implement it?

marble halo
#

In the air state player.velocity.y += player.gravity * Time.deltaTime; FinalVelocity += moveVec += player.velocity * Time.deltaTime; player.trueMomentum = FinalVelocity;

#

worth noting is that when this bug happens im in the ground state

ripe igloo
#

You're doing jump as well?

marble halo
#

in the ground state

# 
             {
                player.velocity.y = Mathf.Sqrt(player.jumpheight * -2f * player.gravity);
             }```
ripe igloo
#

You're not checking if the player is grounded?

marble halo
#

because the player is already in the ground state

ripe igloo
#

Kk, what triggers the air state?

marble halo
# 
        {
            player.SwitchState(player.AirState);
        }```
#

isGrounded = Controller.isGrounded;

ripe igloo
#

What triggers that? How do you change isGrounded? You're doing a spherecast I'm assuming?

marble halo
#

Im using the character controller

#

the character controller has a groundcheck implemented

#

so i figured a spherecast would be redundant

ripe igloo
#

Right, because that issue typically happens with spherecast, to be more specific when the radius of the sphere casted is less than the radius of the character controller then isGrounded can be set to false while the edges of the characters are still touching the ground

#

Just to double check, isGrounded is false when your character gets stuck right?

marble halo
#

is says that isGrounded is true when this happens

ripe igloo
#

Hmm 🧐🤔 So that's not the issue

#

Can you describe the issue more precisely?

marble halo
#

maybe step offset has something to do with it?

ripe igloo
#

Step offset is important when you climb up not down

marble halo
dapper pivot
#

please can someone help me, i want to make lonely mountains style bike movement but cant figure out how????

marble halo
ripe igloo
#

I can see that

#

You mean you want the player to fall, is that the issue?

marble halo
#

no, the issue was getting slightly stuck, i think raising the step offset fixed it

hexed pecan
dapper pivot
#

i have but i havent found any

hexed pecan
#

You can use a world space joint (like ConfigurableJoint) to stabilize and possibly rotate the bike

dapper pivot
#

right now the code looks like this

image.png
#

im thinking about just using rb.AddForce

hexed pecan
#

Bike/vehicle physics isnt an easy subject though

dapper pivot
#

yeah

hexed pecan
dapper pivot
#

i wont add suspension though

#

yeah

#

but then the turning must feel nice but a little bit slippery just like in lonely mountains downhill

#

ill propably add a empty gameobject for the orientation

ripe igloo
marble halo
#

the issue was i was stuck and couldnt go up

ripe igloo
#

I thought your issue was getting stuck climbing down

#

That's what it looked it in the picture lol

#

Yeah, increasing step offset would let you climb up bigger steps

dapper pivot
#

right now im adding drag to mkae it a little bit slippery

hexed pecan
#

Slippery? Sounds like low friction, not drag

ripe igloo
# dapper pivot right now the code looks like this

All what this does is register inputs, what you asked for would require mountains of lines of code lol, so just break is down and make one thing after the other until the entire behavior is complete. So you need something like:

  • Torque
  • Angular momentum (to avoid sharp turns)
  • Gravity
  • Suspension
    ....
dapper pivot
#

thanks

#

ill screenshot this to remember

ripe igloo
#

It was just a small todo list I came up with on the spot, you need to study the desired movement behavior and break it down and implement it step by step

dapper pivot
#

yeah

#

thanks for the help

marble halo
ripe igloo
# marble halo actually increasing the step offset created a new issue, when I jump against som...

So the way step offset work, when your character is walking on a plane and suddenly there's a step, the character stops, let's say the step height is 0.3m, so if you set the step offset to 0.4m you're basically telling the character to climb up any step that's less than or equal to 0.4m. Now if you are facing a 0.6m step you won't climb it since the height is bigger than the step offset, let's say your jump height is 0.5m, so when you jump and collide with the terrain, character controller would calculate the step and determine that it is only 0.1m (the total step height is 0.6m, but you jumped 0.5m), and since that's smaller than the step offset it'll climb it, that's where the stuttering comes from I think

yo i have a slight issue, my character goes on slopes and stuff, nvm 2 issues ig XD, 1st the movement is slowed down from going on slopes, 2nd when i stay in place the character starts to slide off, same goes for terrains and stuff, tho ig thats to be expected, lemme know if i should share the movement code

ripe igloo
#

You mean when you're climbing slopes the speed is slower than normal? And the you're static you still move a bit?

peak elk
#

yep sliding off of it(the slope)

ripe igloo
#

You're probably using rigidbody then

peak elk
#

yea i am

ripe igloo
#

Yep, that's why

peak elk
#

the drag is set to 6 and the physics material have 0 friction

ripe igloo
#

Freeze the movement and rotation in all axis if you don't need them

peak elk
#

i dont see a reason to be it, i also have slope detection and stuff for slopes soo i was thinkin that might be it

peak elk
ripe igloo
#

Yep

#

That'll fix it

#

Probably

peak elk
#

position cant be frozen since i cant move the player then

#

as for rotations everything is

ripe igloo
#

You're using .AddForce()?

peak elk
#

yea

#

as i said i can show you the code if u want

ripe igloo
#

There's no need, I understand the issue, lemme see the documentation real quick

if I want a spherecast without a range (in place) can I just set the distance to 0 ?

or should the direction be the zero vector

private void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.CompareTag("Enemy"))
{
Physics2D.IgnoreCollision(GetComponent<BoxCollider2D>(), collision.collider, true);
}
}

This code works expected however it still detects the initial collision; in which all subsequent collisons are ignored, i want the initial collision to be ignored

#

how can i go about this

potent sleet
ripe igloo
dusk geode
#

yes that is exactly what i want

#

i just do not want to move the spherecast along the direction

dapper pivot
#

i might even try to use a sphere to move around

ripe igloo
dusk geode
#

no that is a spherecast without a radius

heavy lynx
#

So they need to be on the same layer

ripe igloo
dusk geode
#

yes but that is not what i asked thank you

potent sleet
heavy lynx
#

Mb

ripe igloo
# dusk geode yes but that is not what i asked thank you

What I'm saying is, if you set the radius to zero thel it'll probably won't detect anything anymore, since it's not a sphere anymore, it can't report which object is inside it since it became a point because the radius is Zero

dusk geode
#

okay

#

not what im doing

peak elk
#

chat gpt suggested to counter the slope force, tho no clue

ripe igloo
peak elk
#

the stopping especially

ripe igloo
#

Try increasing the drag a bit while moving, rigidbody is quite trickier than character controller

heavy lynx
#

The enemy has 2 colliders one for it's "vision" (circle collider) and one for it's hotbox(poly collider)

#

Hitbox

potent sleet
# heavy lynx Hitbox

so make hitbox a trigger only use that for damage , put the other two colliders on a no-collision in layer based collision ignore ?

#

the hitbox layer doesn't need to be on the ignore layer for movement colliders

#

since it's separate

Is using scriptable objects a good way to make a stats system

clear umbra
#

For events in C# is it better to use static, or to create a singleton for my event? I'm leaning towards static rn since the singleton will just end up being static anyways

ripe igloo
stable rivet
clear umbra
ripe igloo
clear umbra
stable rivet
#

so i'm not sure what you meant by "is it better to use static". That's like saying "For integers in C# is it better to use static?"

#

is this what you wanted?

ripe igloo
#

I belive he wants his events accessible from everywhere in an easier manner than "public" that's why he said static or singleton

clear umbra
#

Yes, so I already have my EventHandler, but I need to register observers for my event from another script

#

and I dont really want to pass a reference of my EventManager to that said script

#

I could use dependency injection in the form of FindComponent or GetParentComponent but that also seems meh since its a runtime operation (granted it will only fire once in start)

ripe igloo
#

Yeah so if the event is something global and important then yes you can use static, just don't use it very often, singletons are designed for a different need (mainly persisting data across scenes) so in this case they would work as well but not the best tool for the job

#

It's best to avoid static as much as you can as well

clear umbra
#

I agree, C# is not my main language, but I come from java and static is definitely seen as "evil"

ripe igloo
clear umbra
#

Alright, well thanks for the insight, I'll probably just use static for now as its not a super large project. Should I find problems with static ill probably switch to dependency injection

ripe igloo
#

Any method of searching for components trashes performance in Update(), because it's cycling hundreds of components every frame, that's why it's best to use them in Start() and cache the returned value in a variable so you can use that variable instead of looking for the component all over again

does anyone know how to edge match with a cellular automata generation

void DrawTiles() {
        if (map != null) {
            for (int x = 0; x < width; x++) {
                for (int y = 0; y < height; y++) {
                    Vector3Int pos = new Vector3Int(-width / 2 + x, -height / 2 + y, 0);
                    tileMap.SetTile(pos, (map[x, y] == 0) ? grassPrefab : waterPrefab);
                }
            }
        }
    }

this is the method i use to draw the tiles
after the cellular auto procedural gen finishes
but how can i make the tiles edges also be pro gened like the rotation of the tiles i have a bunch of sprites have to
form the edges in a straight and corner form

    triangles[2] = 1;

    mesh.vertices = vertices;
    //mesh.normals = normals;
    mesh.triangles = triangles;
}

this works fine for me, i get a pink triangle, even without specifying normals. (specify your normals)

Needed tips to get this (sorry for the amazing art !!), just want to know ur thought on how u would do this.
The user throws a "Lego like" block, which on landing on the ground (lego blocks as ground) will be attached to the nearests (if only have one just one). Just the "attach" part is where i would appreciate some advice. Detecting which ones collided without adding for each "teeth" a collider, or a script making the level not optimised. Sorry if should put this on another channel!

ok so depending on the rest of the context, you might predetermine the angle right when the user 'throws' it, then make it smoothly go towards the exact point you want it to be to look 'attached'

Kinda cleaner too

And works with any amount of variables, as long as there's the same amount left & right

Sure, that would be (l[0], l[1]) = (l[1], l[0])

Hey guys im trying to make a grid system for my game from scrtach and i got this code here and i was wondering how can i spread the points out?

@narrow summit @simple egret
hey, unfortunately, both methods doesnt seem to be working.
I just want to point out that Im testing them via inspector button and not on run time

basically im running a function asking list to switch between item no. 4 and 3 then loop through all entries and tell me each order with its order.
nothing has changed based on what i read on the debug

narrow summit
#

Post code

simple egret
tall lagoon
#

oh thanks

narrow summit

#

Sure you can declare another Vector2, modify it from the Inspector, and add that to the other vector in the for loops

#

That will "offset" the grid by a specific amount

tall lagoon
#

Oh ok

#

like this?

simple egret
#

Or attach the script to an object that's aligned with the floor

#

And yeah, that works

#

new Vector2(...) + Offset; also works, and looks cleaner IMO

tall lagoon
#

thank you

tall lagoon
# simple egret `new Vector2(...) + Offset;` also works, and looks cleaner IMO

Oh 1 more thing but i dont need your help i just need to know if im on the right track.So this grid will be used for my building system right?So i have abutton to spawn a building sowhen i click that building a building will instiate and it will follow the mouse.So in order for this building to snap to the grid i round the posison to the nearest point on the grid correct + the mousepos right?

simple egret
#

Yep, you would take the world position of the object, subtract it from the grid's origin so the position is "relative to the grid", then divide that position by the SpaceBetween, and round down.

#

That way, it works even if you change the size of the grid

tall lagoon
#

ok so a gimme a sec

#

so

#

gimme a sec

tall lagoon
simple egret
#

Yeah, as you add an offset, you now need to subtract that offset so the position calculation is adjusted to the origin

tall lagoon
#

ok

tall lagoon
#

likewhere in the equation?

#

bc right now i have this

simple egret
#

Say your grid cell size is 10, with an offset of 20 on both axes.
You now place an object in world space at (42, 42), and want to adjust it for the grid.
Subtract the offset: (42 - 20, 42 - 20) = (22, 22)

These coordinates are now adjusted, relative to your grid.
Divide by cell size: (22, 22) / 10 = (2.2, 2.2)
Round the positions down: (2, 2)
Your object is to be placed inside cell (2, 2) of the grid.

Now, multiply that back by the cell size: (2, 2) * 10 = (20, 20)
And add the offset: (20 + 20, 20 + 20) = (40, 40)
The position snaps to (40, 40) which is the closest grid point to (42, 42)

#

(going offline for the night now)

tall lagoon
#

ok

tall lagoon
#

Like bc my grid dosent have a cell size

simple egret
#

SpaceBetween is the cell size

tall lagoon
#

oh okay

simple egret
#

Should probably rename that variable

tall lagoon
#

so we should put this equaion in var right?

#

yeah

#

ok

#

then we set the position to that

simple egret
#

Your equation is almost right, just got to put the offset subtraction in parentheses, as the division is done first here

#

Order of operations issue

#

Then, once it's adjusted, you multiply it again by the cell size, and add the offset

#

And done, it's now snapping to the grid cells

tall lagoon
#

Like this

#

oh ok

tall lagoon
#

That correct

simple egret
#

Nope

#

Parenthesize the whole subtraction, not just the variable

simple egret
tall lagoon
#

Thanks man

simple egret
#

Nope, still not

tall lagoon
#

But can you expalin the math

simple egret
#

Parenthesize the subtraction

tall lagoon
simple egret
#

(a - b) / c

tall lagoon
#

seems kinda slow comapred to before

simple egret
#

Still need to multiply and add the offset back

tall lagoon
simple egret
#

Yeah, after that. You don't want to put the result of the rounding into the position yet, because what the rounded vector returns are grid indices, like indices of an array in code

#

Say this returns (5, 1), that means "the 6th grid cell on X, the 2nd grid cell on Y"

tall lagoon
#

Oh

#

i see

simple egret
#

It's not world positions anymore

tall lagoon
#

so we minues 1?

simple egret
#

No, you keep it as is

tall lagoon
#

This is correct right?

image.png
simple egret
#

As if you put an object at (9, 8), it will get rounded down to (0, 0) which is the bottom-right cell

tall lagoon
#

so wait

tall lagoon
simple egret
#

Because with a cell size of say 10, it'll do
9 / 10 = 0.9
8 / 10 = 0.8
Rounded down
0, 0

#

First cell

#

Indices start from 0 just like everything in C#

Sorry to ask a question in the middle of actively trying to help someone, but am I right in concluding that the reason my character isn't responding properly to AddForce right now (trying to implement a knockback mechanic that pushes them backwards when colliding with enemies) is because the movement code is using MovePosition on the rigidbody and it's basically trying to move the same thing in two different ways at once?

#

Still missing the second half

tall lagoon
#

Gmm?

#

I added it

#

just like you said

simple egret
#

Well you're doing that in the middle of the first step

#

After dividing, but before rounding down

tall lagoon
#

ok

simple egret
#

So I really have to go to sleep now so just have some pseudo code

adjustedPosition = objectPosition - offset
indices = RoundDown(adjustedPosition / cellSize)

// the 2nd half, convert indices back to world positions
objectPosition = (indices * cellSize) + offset
#

Try to work with that alright? The first part of your code, where the division is, is not correct anymore

tall lagoon
#

ok

#

ill try

tall lagoon
simple egret
# tall lagoon

On this one, yeah. You don't want to use RoundToInt either because sometimes it rounds up. You absolutely need it to always round down

#

You can cast to int, for that.

(int)3.1 // 3
(int)4.9 // 4
#

It gets rid of the decimals, essentially rounding down

Whats the best way of organizing npc AI scripts? Id like the NPCs to change what theyre doing. For example daily tasks, go home to sleep at night, and hide/run away when attacked

Would it be best to write script for each state and then have the npcs use the scripts specific to circumstance?

Sending this problem here because #💻┃code-beginner is occupied right now, and this seems like a pretty complex problem too that I can't solve.

I'm making a first person character (classic way to start Unity 3D), and all is well. I learned the basics of the code very well and have a somewhat solid understanding of what I'm doing (except Quaternions, I can't stand Quaternions). The only issue I'm still facing is that when I run into an object at an angle, my camera will do a jitter of sorts as I keep walking. Once I leave the object, it is fine though.

This link is both the player movement script, and player camera script: https://hatebin.com/mkbqgierun

I narrowed down the issue quite a bit. The player capsule itself is not jittering, but rather the camera position holder that possesses the player camera script (the parent of which is the player capsule.

I have found that the issue is related to the RigidBody's Angular Velocity, which increases when this jitter also increases.

So my question is what in the world do I do?

hexed pecan
#

I would also try zeroing the rigidbody's angularVelocity continuously

#

Actually, try freezing your rigidbody's Y rotation completely in the constraint settings. You should still be able to rotate via MoveRotation, but collisions shouldn't affect your angularVelocity

red brook
# hexed pecan Actually, try freezing your rigidbody's Y rotation completely in the constraint ...

Third solution did it, thanks osmal (:

For future reference, I tried moving MoveRotation to FixedUpdate, and it made the camera rotation much more jittery whenever looking around, probably because it isn't linked to each frame.

Zeroing AngularVelocity is what I did in the beginning actually, and it helped end jittering once I stopped touching the object. I decided to delete it since it didn't work before I asked for help, yet its effects remained after I had removed the line of code, weird. Anyways I added it back but it didn't change much, it only helps end jittering when the collision ends.

Now, the jittering is over, but my character is very prone to sticking to the wall when walking at it, even if its not a direct angle at all. Is there a way to end wall stick?

hexed pecan
# red brook Third solution did it, thanks osmal (: For future reference, I tried moving Mov...

Nice to hear that it worked👍

probably because it isn't linked to each frame.
Yeah that's probably it, there's a disconnect between the camera and rb rotation.
my character is very prone to sticking to the wall when walking at it
Try adding a physics material with low friction to your capsule collider. I like to keep it at 0 or near 0 so I have more control over the movement

This is my method it is referencing
```private bool isMinimum(List<PrismEyeData> peData, float currentPrism, Vector3 eyePos) // Somehow needs to be called multiple times to double check it is the correct value?
    {
        PrismEyeData currentPEData = new PrismEyeData(currentPrism, eyePos);

        }

        else { Debug.Log("Is not bracketed // Error is logic."); return false; }
    }```
Here is how it is called `isMinimum(prismEyeDataList, prism, currentEyePosition)`
I only created the list like this `private List<PrismEyeData> prismEyeDataList = new List<PrismEyeData>();`
#

Here is the PrismEyeData Class incase it is needed.

{
    public float prismValue { get; set; }
    public Vector3 eyePosition { get; set; }

    public PrismEyeData(float newPrismValue, Vector3 newEyePosition)
    {
        prismValue = newPrismValue;
        eyePosition = newEyePosition;
    }

    public int CompareTo(PrismEyeData other)
    {
        if (other == null) { return 1; }
         
        if (prismValue < other.prismValue) { return -1; }
        else if (prismValue > other.prismValue) { return 1; }
        else { return 0; }
    }
}```

I am thinking maybe the issue is that the PrismEyeData Class doesnt have any MonoBehaviour, but I had an error for some reason having it on the class.

Lists confuse tf outta me, having a lotta trouble getting it to work lol.

Also, IndexOf will return -1 if the peData wasn't present in the list, and that would cause the index to be out of bounds

#

Arrays too lol, havent had to deal with one before. Let me try and remove the Monobehaviour and see if it works...

hexed pecan
#

For example, if currentPEData was the first in the list, then currentindex is 0. And currentIndex - 1 is -1. So you are trying to access the list with a negative index which wouldnt work

cosmic rain

#

Yah im sure its two different errors.

#

How would I catch that? make another if statement checking if it isn't first in the list? thats kinda the entire purpose of the if statement, to check if the currentindex is surrounded by one index above and one index below

cosmic rain
#

A list has a Count property telling you how many elements there are in the list. Check that you're resulting index is below that count and above or equal 0

I've been working on a 3D pathfinding system that uses a modified version of the A* algorithm. One of the challenges I've been having is finding the best data structure to use for the "Open Set" for the algorithm. I'm currently using a weird implementation of a Skip List that I wrote, as it is the fastest thing I have tried, but I don't think that it should be in this use case and am hoping I can still find something better to speed up the pathfinding a bit more.

Does anyone have any suggestions or resources on data structures that might be better than a Skip List for this type of application? The main bottleneck in my pathfinding is maintaining the sorting of the open set and I'm reaching a point where there aren't many place left I could speed up the pathfinding other than using a data structure that could do this faster.

cosmic rain
# wide ermine *float 💀

Ok. First make sure that it really is changing from 0 to 1. Then check your curve and make sure that it takes ranges 0-1.

#

it only is a problem when you aim down sights while an animation is playing

#

once you finished aim down sights its normal

steady thicket
# cosmic rain Something like a quad tree maybe? Aside from that, you could make it async(as in...

Right, I intend to work on multithreading the system down the road but right now I'm trying to reduce the total work necessary to calculate a path before doing that.

I guess what I mean in my question is that a lot of data structures that maintain an ordering allowing you to get a minimum element by some priority (generally called a "Priority Queue" I believe) will do their reordering when an object is inserted.

This generally isn't a problem for 2D pathfinding, as generally a node may only have up to 8 neighbors (accounting for diagonal movement). In 3D and using an irregular octree to create nodes, some of my nodes have many more than 8 neighbors, as there are more directions and in some cases many (some power of 4) neighbors in each direction.

This means I insert nodes to the open set exponentially more often than I remove them, compared to in 2D. I think some data structures (like a Fibonacci Heap) instead handle reordering when the minimum element is removed, rather than when they are added and/or take advantage of other properties of relations of their nodes to speed up the reordering. I'm just not sure exactly how everything works for each data structure and I'm not sure what would really be the best in this use case and am running out of ideas lol.

You need a reference to an instance of the object.
Then you need to use the dot operator: .
then then function name and the ()

what you have is:

  • A class name (not a reference)
  • no dot operator

Non-Monobehaviour scripts can't attach to objects though right?

How useful is it to learn that academically? I learnt everything on my own, so I don't have much perspective. I would argue that you don't need to know how to make a hammer to be a carpenter, although it could help. Thought?

Really just puts more money in my college's pockets. This professor of mine is...not organized or helpful much.

I feel like what I learned in college about programming and how computers and software work was invaluable but I'm sure it can be self-taught as well

I actually used Unity Learn to refresh on concepts and learn new ones because my professor doesn't make sense

#

We will struggle conceptually and he just insults us

🤷‍♀️

doesn't sound like a great teacher

SCAD Atlanta is sad

#

I'll just say that

#

Especially the game dev major

#

anyway I'm venting in a code channel lemme play with the instance thing, thank you

are these teachers getting degrees in cereal boxes?

is there a way that I can get my list of users in firebase and save their data in UGS Cloud Save?

maybe you'd have to write a custom script to migrate

# cosmic rain OOP you mean? I'd say it's one of the minimum requirements for a junior programm...

Not really about OOP, more about the exhaustive aspect of academic learning. For instance, I learned (kinda) late the difference between reference and value type. Is it useful? For sure. It really made me rethink conceptually my approach to coding (in the context of Unity at least).
Would I have been receptive to it in a class where the uses of that concept are described abstractly? I'm really not sure.
There's probably a LOT of subtleties that I neglect while coding. I'm just not sure how important it is to know them all

I tried watching tutorial on Youtube that do explain those concepts exhaustively, and I'm not sure how useful this has been for me.

If you're just letting that info go through your ears, there's definitely no much point in it. It is best to learn while actually doing something. For example, when you're implementing some code in your project, inspector every line carefully. Do you really understand the meaning of that syntax/function/type? Let's say you see a Vector3. Why is it colored differently than other types? What is it a struct? Why is it a struct and not a class? Once you start asking and researching these kind of questions, you'll really start learning. Then also try to experiment on your own given the acquired knowledge. Can you make a class vector? What does it imply? How is it different?
Stuff like that.

Makes a lot of sense. I started with the pragmatic approach "how do I code something that does this?", and lean more and more to an abstract one "how does it work?" "could it work differently?". I think it's the best approach, since I always felt at my level of understanding, which keeps it compelling.
That being said, I'm a bit envious of some of you guys that understand it more thoroughly because of the basic concepts taught in school, but that could be me being biased, and a simple lack of experience.

what does this mean:

#

im comparing two float2s

#

not had that error before 🤔

quartz folio
#

float2 == float2 produces a bool2, just use .Equals or similar

broken light
#

oh so i need to do:

        public bool Equals(in Edge edge)
        {
            bool2 flag = _a == edge._a;
            bool2 flag2 = _b == edge._b;
            return flag.x == flag.y == flag2.x == flag2.y;
        }
``` ?
#

not really sure i understand the syntax of their bool2 type kinda odd

quartz folio
#

no, that doesn't make sense I think

#

just use Equals

main shuttle
#

Declaration
public bool Equals(object other);
Description

Returns true if the given vector is exactly equal to this vector.

Due to floating point inaccuracies, this might return false for vectors which are essentially (but not exactly) equal. Use the == operator to test two vectors for approximate equality.

#

Docs suggest using == instead because of the approximate nature

broken light
#

where you get that quote from

main shuttle
#

The docs

broken light
#

for vectors?

#

yeah im not using vectors

main shuttle
#

Ahh float 2s

#

I thought vector2's

broken light
#

unity usually implements override for their comparisons anyway

#

so a==b for vectors should be fine

#

as would equals

why In?
