if that keeps happening the loop will run forever

I see thx

@deep fable
I think that in a lot of games with big stadiums they render the closest people as 3D and the further away ones are just 2D textures.
I think they use Blender (or w/e 3D program) and made an animated render of the 3D people so that the textures look like the 3D models from a distance.

This is just something that I've read and I don't have experience with it myself.

Bumping: So I have the following problem: I'm using a rigidbody for my character. It has a physics material of friction 0 and bounce 0 (uses min value for both). Friction is 0 because I'm calculating and applying friction manually when the character is grounded.
When my character lands on a slope from a long fall, it slides a little before it stops.
Any ideas on how to prevent it from sliding on landing? I tried canceling velocity on OnCollisionEnter and also on FixedUpdate but nothing seems to work. I'd rather avoid Update because I want to keep the movement as frame-independent as possible.

coarse gull
#

Can someone help me? My character is rotating and moving nicely taking in consideration the cinemachine direction, but when I release any input key it keeps the movement infinitely in the last direction calculated.

    void Update()
    {
        ApplyRotation();
        ApplyGravity();
        ApplyMovement();
    }

    private void ApplyGravity()
    {
        if (IsGrounded() && _velocity <= 0.0f)
        {
            _velocity = -1.0f;
        }
        else 
        {
            _velocity += _gravity * _gravityMultiplier * Time.deltaTime;
        }
        
        _moveDirection.y = _velocity;
    }

    private void ApplyRotation()
    {
        if (_input.sqrMagnitude == 0)
        {
            return; // No input == keep current direction
        }

        var targetAngle = 
            Mathf.Atan2(_direction.x, _direction.z) * Mathf.Rad2Deg + _cam.eulerAngles.y;
        var angle = 
            Mathf.SmoothDampAngle(
                transform.eulerAngles.y,
                targetAngle, 
                ref turnSmoothVelocity, 
                _turnSmoothTime
                );
        transform.rotation = Quaternion.Euler(0.0f, angle, 0.0f);

        _moveDirection = Quaternion.Euler(0.0f, targetAngle, 0.0f) * Vector3.forward;
    }

    private void ApplyMovement()
    {
        _characterController.Move(_moveDirection.normalized * _moveSpeed * Time.deltaTime);
    }

    public void Move(InputAction.CallbackContext context)
    {
        _input = context.ReadValue<Vector2>();
        _direction = new Vector3(_input.x, 0.0f, _input.y);
    }

I believe it has something to do with not reseting the _moveDirection variable every frame. But I've been trying to fix this for the past few days and for some reason I can't really figure it out.
Any help is appreciated! :)

2 things.

  1. _input.sqrMagnitude == 0 is a float. you should never test floats for equality
  2. _moveDirection is a Quaternion. You should never alter idividual components of a Quaternion
hexed pecan
#

Isn't it a Vector3 not a Quaternion?

knotty sun
hexed pecan
coarse gull
#

Alright. Let me try

coarse gull
hexed pecan
#

Or your _input.y instead of _direction.magnitude, whatever you like

coarse gull
#

I appreciate the help but I think it is more messy right now.

#

I'm considering remaking the whole code. It's already been a few days of trying new things and asking for help online sadok

#

But thank you very much for your time!

hexed pecan
#

I don't see how changing a couple of words is messy

#

You can always use Vector3.forward * _direction.magnitude instead of new Vector3(0, 0, _direction.magnitude); if that helps keep it less "messy"

#

But you do you 😄

coarse gull
#

Messy in terms of gameplay. I've changed a few things and it is a little bit better now

#

But it still keeps on moving forever if I release all keys

hexed pecan
coarse gull
#

and gravity is only being applied when no key is pressed.

hexed pecan
coarse gull
#

Hmm, tried it and still the same.

leaden solstice
#

Literally

#

Lol

coarse gull
#

How can I fix it?

hexed pecan
#

You probably want the latter option

#

If you don't want your rotation to update when not moving

coarse gull
#

It is now looking very good.

#

Gravity is not being applied tho.

hexed pecan
hexed pecan
#

Do you see why it matters? ApplyRotation is setting moveDirection's Y value to zero

hexed pecan
#

So you want the gravity to happen after that

Can't thank you enough

coarse gull
cobalt wave
coarse gull
#

Thank you very much for the help @hexed pecan

acoustic dagger
cobalt wave
#

well

#

find a game object with the tag you want (not in the update method, since finding is costly)
and make the camera follow it

# 
void Update()
    {
        Vector3 relativeOffsetPos = target.TransformPoint(positionOffset);
        transform.position = Vector3.SmoothDamp(transform.position, relativeOffsetPos, ref velocity, smoothAmount, followSpeed);
    }

this is how I do it

#

this always looks relative to the player

acoustic dagger
#

o shi you fast

#

tysm

cobalt wave
#

welcome and good luck

coarse gull
#

BTW, currently everything about my movement is tied to the _moveSpeed because of this line

_characterController.Move(_moveDirection * _moveSpeed * Time.deltaTime);

How could I untie the falling movement/speed from the _moveSpeed variable?

hi,
does anyone knows how to draw 1/4 of a circle ?

vec3 rgb(float r, float g, float b) {
    return vec3(r / 255.0, g / 255.0, b / 255.0);
}

/**
 * Draw a circle at vec2 `pos` with radius `rad` and
 * color `color`.
 */
vec4 colorAndBlur(vec2 uv, vec2 pos, float rad, vec3 color) {
    float d = length(pos - uv) - rad; // blur edge
    float t = clamp(d, 0.0, 1.0); // color
    return vec4(color, 1.0 - t); // color
}

void mainImage( out vec4 fragColor, in vec2 fragCoord ) {

    vec2 uv = fragCoord.xy;
    vec2 center = iResolution.xy * 0.5; // position
    float radius = 0.25 * iResolution.y;

    // Background layer
    vec4 layer1 = vec4(rgb(210.0, 222.0, 228.0), 1.0);
    
    // Circle
    vec3 red = rgb(225.0, 95.0, 60.0);
    vec4 layer2 = colorAndBlur(uv, center, radius, red);
    
    // Blend the two
    fragColor = mix(layer1, layer2, layer2.a);

}
#

like top right corner of a circle, top left , bottom right , bottom left ?

hexed pecan
#

By calculating a distance from the pixel to some corner

coarse gull
solemn raven
#

it will always be the same = radius

heady iris
#

although, it is nice to see an example of Move being called twice -- I had a superstition about not doing that for a while

#

(something about messing up isGrounded -- I guess that could be an issue if you did gravity first)

hexed pecan
#

I lived under the impression that the doc is wrong

#

But I dont really use CC

heady iris
#

i should really just test it

#

it's not that much

hexed pecan
#

Like I've just heard that youre supposed to combine your Move calls into one per frame, not sure what was the reason, maybe the isGrounded stuff you mentioned

Hello there , may I ask, what is Graphtools? I was looking for some way to mess with UI toolikt and make graphs into it, but I found this package which doesnt seem to be what I was looking for, but confuses me about its functionality, what is it supposed to do?

for example Shader Graph, VFX Graph, and Visual Scripting are graph-based editors

can It work with jobs ?

#

or its just for visualiation

Hey, are my inputs frame dependent if I use events with the new input system? If I make a jump with a height proportional to the time the button was pressed, and I press it 2.1 frames, will it behave as if it was pressed 3 frames?

quaint escarp
#

I've been building an "unique id system"; using Type and ulong; I've been very careful so that I can release an unused id and reuse it to another entity, when there are spawns and despawns; I was using Dictionary<Type,List<ulong>> but I recently moved to Dictionary<Type,HashSet<ulong>>; this prevents the id to be repeated, but I'm using this just to be sure I won't use a released id twice; I tried very hard to keep track of my code so I actually don't release the id twice or more, using other variables to check, so that I didn't even need to use HashSet in the first place; I just changed it to HashSet as a "safety measure" because I'm really afraid of doing a mistake in the code and cause a bug to release the id twice; does anyone have a method or has knowledge on how we can be more trustful about our own code? I've been reading and rereading my code and it's working as expected but I'm really scared of causing a corrupt game file with repeated ids. I don't know what to do to be sure it's going to keep working as expected.

leaden solstice
quaint escarp
# leaden solstice What are you using this 'unique id system' for?

I'm using it for identifying an object as "spawned" so it can be saved in the game files with its own properties; whenever I despawn an object and it no longer exists in the game, I release its id for a next object of same Type to use it and pool the GameObject without properties for a new spawn

leaden ice
#

Note that "frames" are not generally a meaningful measure of time because framerate will always vary.

golden vessel
leaden ice
#

Yes of course

#

everything in Unity is based on frames

golden vessel
#

They're checked every frame

leaden ice
#

yes

golden vessel
#

Right ok, thanks

#

Can be weird in low fps

leaden ice
#

potentially sure

lots of weird things can happen at low framerates

Anyone ever implement the IPointerClickHandler interface for tmppro dropdown items? Currently there is only an onvaluechanged interface but I want to get events sent to me when an item is clicked even if it was selected before and the value did not change

leaden solstice
void basalt
#

Said this before and I'll say it again. Avoid GUID for tagging objects with an ID.

leaden solstice
#

Context?

void basalt
#

There's just no reason. Use uint and just reuse IDs.

#

I can name many things wrong with GUIDs if thats what you're asking

heady iris
#

can you name them, then?

leaden solstice
#

He is worried about 'releasing same id multiple times' for some reason, then simplest answer : use GUID and don't worry about releasing anything 😄

heady iris
#

i can certainly gripe about the lack of serialization support

cosmic rain
void basalt
#

It's just an awful habit

#

you also aren't going to be mapping the ID to an array index with GUIDs

heady iris
void basalt
#

small integers compress fine

heady iris
#

this is nonsense

leaden solstice
#

Awful habit that is widely used and battle tested? Sure 😄

void basalt
#

widely used by who?

heady iris
#

you do not know what you are talking about

#

at all

leaden solstice
#

Literally everyone include Unity itself

void basalt
cosmic rain
#

I kinda agree with Burt. Depending on the use case it might be different, but I think in most cases using GUID is an overkill. It's like using nuclear missile launch protocols to open your fridge.

heady iris
void basalt
#

That's pretty much what I'm talking about, chief

heady iris
#

then you should say so.

void basalt
#

or you could stop embarrasing yourself

heady iris
#

particularly small, sequential integers

void basalt
#

either way works

#

I'm done with this conversation

heady iris
#

anyway, back to productive conversation...

heady iris
#

it also prevents stale IDs from suddenly becoming "valid" again

#

which is a nice simplification

#

however, if you would like to hold all of your entities in an array, then it is very natural to use array indices as IDs

#

and this, of course, makes it very efficient to store and retrieve your entities

leaden solstice
#

I mean there won't be anything that'd make your code perfectly trustable, even if you use Rust 😄
Best practice, add enough assertion and make test cases

quaint escarp
# leaden solstice You could use `GUID` or similar stuff and forget about releasing it 😄

I'm using ulong because of GUID can be unpredictable sometimes; I'm using a list of ids of unlong and reusing them whenever they are not used anymore; the code is working fine, I'm just afraid of making mistakes in the code from now on. The problem with GUIDs might be using the game save between computers. Wouldn't there sometime a possibility of a repeated GUID?

"Best practice, add enough assertion and make test cases"
I think that's the point I'm looking for; but even doing that there's no way to create a "perfect", no mistakes code, is there? I'm testing now, and rereading but I'm so afraid of causing a "collision" in the ids that I froze in place in front of my computer and I can't add more stuff; if a collision happens; I believe, in the way I coded, the worst that can happen is that the old real id owner object will vanish so the new id one will spawn, or the save file will be left with some strings of the old object, but with no usage in the next load.

void basalt
#

but there's nothing checking for it.

#

that will be the least of your problems when using GUID.

#

Also extremely unlikely that you'll exceed the uint range. Ulong is unnecessary for this.

void basalt
#

@quaint escarpOverall, you should make sort of a mini "library" for managing IDs, so that you don't have to worry about shit breaking randomly.

heady iris
#

If these are sequential values that you re-use after freeing them, then you can absolutely get away with a uint

leaden ice
heady iris
#

maybe even an unsigned short, but that's starting to wander into the realm of "maybe I will have a few tens of thousands of objects"

this is my variables definition, my code is spread in three files, the sim object manager, the sim object spawner and the persistent sim object data saving

When you're doing stuff like this, you can always inherit from monobehaviour and create your own entity class

it should behave pretty nicely on average

with an attached ID

and just instantiate those rather than default monos

much easier to keep track of things

"despawning" and "despawning and releasing ID"

quaint escarp
#

If I could share my screen I could explain better, but I'll try to do it through text:
my game code is here, anyway, if it helps: https://github.com/Arthur-Kenichi-Condino/AbSolitude

  • the game is open world with editable terrain (marching cubes), and biomes can be created with LibNoise for Unity library
  • object despawning is because objects can be off screen and then saved to the files in that state, and they disappear
  • object deswpawning with id release is for when trees are for example broken and they no longer exist; but a new tree can be placed so the id can be used again
  • active is an object that has the function ManualUpdate() called
  • spawned is an object that may not be active anymore but is marked to be pooled (it still exists in the game)
  • the trees in the picture are 7 meters tall
  • the weapons floating are the inventory system that I am implementing. (the bug is fixed already, no new weapons are left floating after new saves)
SPOILER_image.png
void basalt
#

Just prevent your entity from moving backwards

vast pumice
#

how should i do this

void basalt
#

Is this like chess or?

vast pumice
#

ye very similar to chess

#

but with diffrent pieces

void basalt
#

So why are you putting board game slots in a list?

#

Valid move positions?

quaint escarp
# quaint escarp If I could share my screen I could explain better, but I'll try to do it through...

So this is what was bugging me:

  • the inventory system also has an unique id system: an inventory is attached to a sim object (like a tree or the character), has its id and is saved to the files
  • an object added to the inventory has its slot id inside the inventory
  • inventories also have the reusable id system:
     internal readonly Dictionary<Type,HashSet<ulong>>releasedIds=new Dictionary<Type,HashSet<ulong>>();
     internal readonly Dictionary<Type,LinkedList<SimInventory>>pool=new Dictionary<Type,LinkedList<SimInventory>>();
     internal readonly Dictionary<(Type simInventoryType,ulong idNumber),SimInventory>assigned                 =new Dictionary<(Type,ulong),SimInventory>();
     internal readonly Dictionary<(Type simInventoryType,ulong idNumber),SimInventory>active                   =new Dictionary<(Type,ulong),SimInventory>();
     internal readonly Dictionary<(Type simInventoryType,ulong idNumber),SimInventory>unassigningAndReleasingId=new Dictionary<(Type,ulong),SimInventory>();```
- unassigning and releasing id is an inventory that is being released because its owner was removed from the game (like a despawned tree that may have its fruits removed)
- active is an inventory that is fully functional
- assigned is an inventory that may not be active but is going to be added to the pool
- when there's an inventory release, all sim objects inside of it also are despawned
vast pumice
void basalt
#

@quaint escarpThis definitely isn't how I would do it

vast pumice
#

if its avaible its green

void basalt
#

@vast pumiceI've never played chess in my life, so I can't help you much more, but you should simply move pieces based on their characteristics

#

you'll end up with different class types for each chess piece

#

@quaint escarpYou should never need to "release" an ID.

#

if that makes sense

heady iris
# vast pumice

rather than deleting options from a list, it seems more reasonable to add valid moves to a list

#

if a piece is allowed to move diagonally once, followed by a forwards rook move, then you can just walk those two possible paths

#

and halt once you run into an obstacle

void basalt
#

@quaint escarpYour inventory should be as simple as possible. It should simply just be an array/list

#

then you can index into it

quaint escarp
#

I'm working this way because it's a game like Ragnarök Online where a lot of monsters spawn and die, through the map, repeatedly, and they have their inventory data, and lose it when they die

void basalt
#

That's not a problem

#

You need a proper entity system first

#

you need a function that can call like "myInstantiate" and it automatically instantiates a new entity for your game

#

automatically tagged with an ID

heady iris
vast pumice
void basalt
#

then have a function on it called "Delete" that automatically goes through and wipes everything

heady iris
#

(possibly including a move capturing that piece if it's a legal move)

heady iris
vast pumice
#

okey thank you very much both of you guys

tropic quartz
#

An another option for a grid based game is to have a 2D array and just use the grid to make checks.
Though I'll admit that after making a Tetris attack style game using a 2D array in the past... they can be a huge pain to get used to tbh.

you just need some way to query "is this space occupied (and by whom?)"

#

a 2D array certainly makes that easy

vast pumice
#

I already have that

#

Every square in game have tile script which has IsFull bool

chess piece checking if its empty before moving but the other tiles behinde is remaining Isfull = false

#

so checking one by one then stopping is what i will try i think

thank you; I'm doing a process that follows this idea; the variables are a little confusing maybe because they keep the objects' references for easy access in the functions, so for example, the "instantiate" you mention, in my game, it saves the variables in ids and active and spawned, but when I "delete", they are placed in despawning because they'll be saved and them removed from the other variables and added to the pool. I reuse objects so I don't need to Destroy and Instantiate all the time.

void basalt
#

Your IDs can be mapped 1:1 to their reference in a simple array

#

no need for dictionaries

#

avoid dictionaries if there's a better way to lookup in a list/array

quaint escarp
void basalt
#

alright I guess thats fine

#

for example, before my game gets built, it goes through each type and assigns a custom "asset ID" to it

#

so that other computers understand what type of object they need to spawn in, based on a small integer

#

there's many ways to accomplish this

quaint escarp
#

thank you for all the help.

Maybe I overcomplicated but I can't change all of it now, because it's how the saving and loading system also works (in background); maybe when I have more time to polish the game, but now I need to add the other features.

The main point of not having a way to predict and avoid all bugs even if adding lots of asserts all they way and doing many play tests is what I wanted to understand: I think it's pointless to stay still in front of the computer reading and rereading for so long; there's always the risk to create new bugs when adding new features, like the floating weapons when I added the inventory system.

I'm using GitHub to check changes and sometimes "go back in time", but even with that sometimes I can't delete other stuff I already added; I was looking for the best practices to keep the code clean and organized, because it's too much from my lifetime (approximately 10 years of learning C# and Unity and coding this project) to restart from zero now.

When I was younger, I had a lot of GitHub repositories of this same project, I don't want that to happen again.

void basalt
#

"like the floating weapons when I added the inventory system. "

#

This is what the entity system is for

#

creating/cleaning up everything so you don't have to

#

You definitely want this solid before you start working on gameplay.

quaint escarp
#

I'm not sure how to implement this ECS now, but I'll study it; I think it didn't exist yet when I started my project.

void basalt
#

each "entity" already has an integer ID attached to it.

I've got a class called Agent, it handles conversations. Being able to input and output words is pretty much what it does.
In this class I have two events:

public event Action<string> OnHear = delegate { };
public event Action<string> OnSay = delegate { };

I want other scripts attached to the Agent GameObject to be able to read when these are invoked.

Another class that inherits from Agent is AIAgent, this class uses AI to create responses.

When trying to invoke the events in AIAgent however, I can't. Is there a fundamental feature with inheritance that I'm missing here?

somber nacelle
#

events can only be invoked from the type they are declared in. and yes this means inheriting classes cannot directly invoke a base class's event. You could instead use a protected method on the base class that your inheriting classes call to invoke the event

okay, will do. Thank you!

Well, to start off, start throwing some debugging before, inside, and after your statements which you're trying to grab a reference,

grave nebula
latent latch
#

Right, so it seems this method isn't finding any game objects with your preferred tag, and as a result it returns a null.

grave nebula
#

so this thing

#

I have playercontroller inside player and Game inside MainGame

image.png
quartz folio
#

where?

grave nebula
#

?

quartz folio
#

Are you saying MainGame is tagged with "Game"?

grave nebula
#

yes, though I just renamed it to MainGame (the script)

quartz folio
#

can you screenshot that object in the inspector?

grave nebula
#

lemme assign those things too

image.png
quartz folio
#

It is untagged

#

and I do not see the Game script

grave nebula
#

oh you wanted the playercontroller script? for some reason those objects don't appear

image.png
quartz folio
#

I want to see how this works

image.png
#

Ie. the object tagged as "Game" with the Game component on it

#

because if gameScript is null as you say, well, the thing that is assigning it must not be working

grave nebula
#

I took that off of a forum

ruby fulcrum
grave nebula
#

I wasn't sure if I had to specify they != null part in csharp so I just did

quartz folio
ruby fulcrum
#

ohh

grave nebula
#

in this case I don't think it would've mattered

quartz folio
grave nebula
#

I did understand somewhat

grave nebula
quartz folio
#

Perhaps start at step 1 and say what you're trying to do, because I don't really know what you're asking

grave nebula
#

ok

#

I have a function in my MainGame script called getLevel and updateLevel which are both exposed. I want to call these functions from my PlayerController script. That's it.

quartz folio
grave nebula
#

is there a difference between these two

image.png
quartz folio
#

private things are not visible from other scripts. So if you don't intend to ask the PlayerController for the reference to MainGame, then it should be private

grave nebula
#

no i meant the serialize field

quartz folio
#

SerializeField is required to serialize private variables

grave nebula
#

from what I'm seeing on the docs, I don't need to set the script reference. All I need to do is drag the object into the reference box in inspector and then call functions via mainGameObject.getLevel()... correct?

ruby fulcrum
#

i might be wrong but serializefield basically means whether its displayed in inspector

#

if you dont want a public variable to be displayed in inspector use [NonSerialized]

I am having a problem I tried EVERYTHING i could think of for. I spent the last 3 days stuck on this and I have zero idea what to do. Basically my game has a swap from a car controller -> an fps controller. For some reasons when I press my key F to make the swap the object spawns in like 30 billion miles away (video attached).

Here is my switch script

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

public class enableStuff : MonoBehaviour
{
    public GameObject player;
    public GameObject car;
    public GameObject sphere;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.F))
        {
            Debug.Log(car.activeSelf);
            
            if (car.activeSelf == true)
            {
                player.transform.position = car.transform.position;
                Debug.Log("EE");
            } else {
                car.transform.position = player.transform.position;
            }

            player.SetActive(!player.activeSelf);
            car.SetActive(!car.activeSelf);
            sphere.SetActive(!sphere.activeSelf);

        }
    }
}

Anyone know what I should do?

The error in your console is also probably not a coincidence

gameScript is still null.
I've looked up it several times and everyone says that doing it like this should've worked

All you did by adding SerializeField is expose it in the inspector. If it's still empty, you defeated the purpose

Why, you can only assign components. Scripts files are irrelevant

so that I can get the script file to not be null

Assign a component instance of it.

Not the script itself

The MainGame gameobject? or is this something different

quartz folio

Does MainGame have that script on it? Then yes

how do I get the script from MainGame

Presumably the player controller is on the player

grave nebula

correct

Why are you not dragging that into the slot?

you're assuming I have any experience with this

Invoke("ChessBoardPlacementHandler.Instance.ClearHighlights()", 2.0f);
#

Is there anything im missing?

dusk apex
#

Maybe show the console tab with all errors.

#

Usually you'd just provide it the name of the function as a string and some delay value.

#

If anything, you might be able to forward call a method from a different scopecs void A() => B.Instance.C();

# 
Invoke(nameof(A), 5f);```

So I’m working on a dungeon generator for a game and it works on a very small scale like with one room in a 40x40 grid but if I want to add more than one room I need to make it bigger. Since some of the code loops through all the points on the array that causes an issue cause there are multiple for loops that loop through 400^2 different items. Is there a better way to do this

If you mean nested loops, then it's a good practice to move the heavily nested code to a new method. It would make the code more readable.
In terms of optimization, sometimes putting everything inside of a single loop can change the way code works, so often it's better to leave it as it is. Usually, you shouldn't care about micro-optimization unless you observer some severe spikes in the profiler.

tropic quartz
#

I made a small random dungeon game once. I just used a 2D array, called them x and y.
Iterated through it with nested loops.
Put them inside a function I called "SpawnDungeon()" or whatever.

I don't think generators need to be super optimized (on PC at least) since you aren't running them that often.

Hello, I have this code to click on a specific GameObject collider and show its UI to upgrade it, but when an enemy approaches its colliders this code stops working, there is some order of priority that is preventing the raycast from reaching to the collider that I want ?

firing a raycast with a zero-vector for the direction seems very weird...

but yes, a Raycast will only hit one object

Thanks to both of you, I'll try it, I'm new and I don't know much about raycasts, what documentation/source do you recommend to learn?

heady iris

the unity documentation!

#

note that if you're just trying to click on something, I'd...you know, what would I reach for?

in 3D, it'd be a raycast

but that's not really practical in 2D

Hello. I have a question regarding design philosophy in unity. I am trying to make a 2D monster collection game with pretty much turn based combat and pretty standard jrpg mechanics.

My question is: How do you decide when to make a new scene/what to split in multiple scenes? I heard the approach to do it ala Zelda (each cave and dungeon is its own scene), or doing it just all on one scene.

What philosophy do you follow?

heady iris
#

a scene should have very narrow connections to other scenes

#

so, a dungeon makes sense as a scene

gloomy mortar
# heady iris so, a dungeon makes sense as a scene

hm ok. I thought about splitting certain GUI areas into scenes.

Like inventory, combat screen and stuff like generically repeating shops. But you would make a lot of scenes, from what I understand? Wouldnt that be a lot of duplicate code? Copying all the stuff for gameplay into each scene?

#

I pretty much plan to make this my first project in this environment and I want to do it correctly so I don't get bad practices ingrained in me 😄 thats why I ask

lean sail
#

sorry if i misunderstand what u are asking, but a new scene is not a copy of your project. Your scripts still exist under assets and can just be applied to things in a scene

How can I find the force to add to a rigidbody in order for it to keep its altitude?

leaden ice

well actually that won't preserve the altitude it will preserve vertical velocity. If you are at 0 vertical velocity it will preserve the altitude

If you want to preserve the altitude you'll need a PID controller basically, if you want it to be realistic

A PID controller?

leaden ice

heady iris
#

yeah, it's very easy to get mixed up

#

can I get a sanity-check on this saving and loading strategy? An "uplink" is basically a save point. UplinkSpec is a scriptable object containing a name and other data, plus a GUID to identify it. It's a custom (and serializable) GUID type, so that's not an issue.

I'm recording a list of save points the player has reached.

https://gdl.space/omisigumot.cs

#

It kind of feels like I should be defining how to serialize an UplinkSpec and then just serializing the entire Progression class

#

but I dunno what's "normal" here

leaden ice
#

checkpoints you've reached/unlocked?

heady iris
#

all of the uplinks you've reached

#

yeah

leaden ice
#

Seems like you'd just have a list or set of Uplink IDs for that

#

not the whole UplinkSpec

heady iris
#

the game manager has a Progression field on it, and I'll have things tell the game manager about progress

heady iris
leaden ice
#

Does that need to go in the save file?

#

Or is that data part of the game build

heady iris
#

Only the GUID is being serialized

#

Resources.LoadAll<UplinkSpec>("Uplinks").ToDictionary(x => x.Guid);

this is fetching all of the UplinkSpec assets and making a dictionary to look them up by their guid

#

so here's an example json blob

leaden ice
#

I'm not sure I'm convinced the deserialization will work.?

heady iris
# 
{
    "uplinks": [
        {
            "m_Value0": 853682203,
            "m_Value1": 1180124283,
            "m_Value2": 3413183312,
            "m_Value3": 3594981305
        }
    ]
}
leaden ice
#

data.uplinks.Select(x => uplinkMap[x]).ToList();
if uplinks is List<UplinkSpec> how are you using x which is an UplinkSpec as a key in that dictionary?

heady iris
heady iris
# 
[Serializable]
public struct ProgressionData
{
    public List<Guid> uplinks;
}
#

this is one issue: there's the "progression" class and the "progression data" struct

leaden ice
#

Ohhh

#

I was confusing Progression and ProgressionData

heady iris
#

yeah, that isn't clear at first glance

#

That might be why I think I have a problem 😛

leaden ice
#

yeah it's kind of onfusing

heady iris
#

It'd be nice if I could just have Progression, and not need to hand-build anything

leaden ice
#

So basically - if you want this to be clean you would fully embrace the "memento" pattern

#

I think you kind of have a mixed model here

heady iris
#

that's a new one

leaden ice
#

Progression is partially serving as a runtime data structure and partially as a storage/serialization data structure

heady iris
#

yeah

#

(to the point that it actually just updates itself when deserializing, rather than there being some static "deserialize" method that returns a new Progression)

leaden ice
#

https://en.wikipedia.org/wiki/Memento_pattern
This pattern is basically just making sure you have a clear separation between the two. You have a runtime Progression object and a ProgressionMemento object which is for serialization

#

IDK if this is the "best" approach but I think it would alleviate the confusion aspect a bit

heady iris
#

although, I think the Progression object does stick entirely to runtime data -- it's just that it has the serialize/deserialize methods stapled onto it

#

it's strictly a list of uplinks (so far)

heady iris
#

i need to think about that some more, too

#

back when i was doing extremely janky javascript-based browser stuff, I just slapped a version number on the save, and then ran it through a series of "migration" functions to get it up to the latest version if needed

#

It was a pretty convenient strategy. If version 5 of the save format added a new list of florps, I could just add an empty list to the save object to migrate from 4 to 5

#

i have no idea what yDiff is

lament bloom
#

I'm using an animation from a unity store anim pack that comes with a lot of extra stuff i don't necessarily need. I created a state in my player's animation controller and added an animation from the pack as the motion for this state, but I'm finding that upon entering it, some code in a StateMachineBehavior defined by the anim pack asset is throwing NREs. The problem is, I never attached this behavior to my animator state, and I can't find out how to make this code stop running

it isn't changing halfway through the loop

i thought you were doing something in side the loop that was throwing an exception and bailing out

it does, indeed, feel like two different components

If this is a component on an object, put , this); in the log so you can click the log and see what object it originates from. If yDiff is a constant, like you say, then this is two different objects.

heady iris

it's throwing an exception and bailing out

#

either:

  • yDiff is somehow changing
  • you have two copies of the component, as Nomnom is saying

It depends what u mean call it in a function, u can spawn one in yes

gloomy mortar
#

pokemon just as an example. My game is not really pokemon, just in the same genre of gameplay

lean sail
#

it wouldnt even really be a huge game object but generally yes u would want to bring the whole gui as one object rather than trying to load like player health, enemy health, player combat bar, etc etc

#

assuming you always want to load every element in that prefab

gloomy mortar
#

in terms of GUI

lean sail
gloomy mortar

#

what i said might not relate depending on how you want your game. Like lets say before the fight you have health or some information displayed on screen. The prefab you have for initiating a fight shouldnt have that health or extra info inside it as well

honestly u can just ignore that last part if it doesnt relate and experiment with it in your game

Hi all, I'm currently working on a 2D project where I have 3 character types: Human, Goblin & Skeleton. Each character type has it's own animations, which in turn limits the actions they can take e.g. mining, attacking, walking, fishing, etc, but they all share common logic such as health, taking damage, movement, etc.

I also have 2 ways of controlling these characters, either directly by a player, or by an AI. The goal here is to allow a player to inhabit any of the characters in the world.

What would be the best way to design the code here?

#

I'm relatively new to unity so I'm still wrapping my head a bit around the script vs game object thing

so a interface for handleEvent function in the sublcasses that the parent can call?

gloomy mortar
# woeful slate so a interface for handleEvent function in the sublcasses that the parent can ca...

possible. But I would just make all of it in the class definition:

Base Class would contain stuff like general definitions for animation names and stuff that is identical.

Base Class also contains a rudimentary string event system that corresponds to animation names you select, but what the string calls will be assigned in the super class (human, goblin etc)

Then create a Human class, which inherits from base class.

#

with this, you can use stuff like "Attack", but have it correspond to different animations based on super class. But you can handle the super classes like Base because they inherited from Base. This enables you to use them in a generic way, but you have to cast them properly if you need animations and such.

woeful slate
#

I'm not sure I fully follow, animations are defined in an animation controller right?

#

or is that not required

gloomy mortar
woeful slate
#

one thing that might help clear this is up is I think you mean to subclass rather than super class

gloomy mortar
#

and would probably be done through a dictionary that contains animation strings (Attack, Walk etc) and would be filled in the super class

woeful slate
#

because Base is the parent (super) class and Human is the subclass

gloomy mortar
#

I meant subclass if you see it like that

woeful slate
#

how would the child subclass define the animations to be played via this string system

gloomy mortar
#

for example

gloomy mortar
# woeful slate how would the child subclass define the animations to be played via this string ...

Dictionary contains:

Attack, 1
Walk, 2
Death, 3

And is located in base class (super class)

Then you inherit from it and create the human class.

Which contains a animation call interface that takes a string.

It uses the base dictionary to translate string to key.

THen you have a dictionary in the subclass (human), which assigns

1, [Animation Handler for Attack, for human]
2, [Animation Handler for Walk, for human]
3, [Animation Handler for Death, for human]

If you do it like this, you can add any number of unique animations depending on the race.

What are the advantages in using singletons\scriptable objects compared to static classes? Right now I'm coding an Audio Manager and it works just fine with a static class. Just wondering whether there are some consequences to that I'm not aware of.

late lion
#

But if you're marking your singletons as DontDestroyOnLoad, then you have the same problem anyway.

fast belfry
heady iris
#

i'm not sure that random singletons would be super relevant when it comes to memory consumption

#

the big question here is whether the singleton is a unity object or not

#

if it's a gameobject, then it needs to exist somewhere in the scene (so you need to DDOL it to keep it around between scene changes)

#

if it's a scriptable object, then it doesn't need to exist in a scene

#

and you get the...extremely confusing behavior of SOs in editor vs. in builds

fast belfry
#

And I guess dependencies are a bit clearer with SO

#

But if I don't really care about injecting into unity lifecycle using a static class should be ok?

heady iris
#

here's the thread i was struggling to find

late lion
heady iris
#

i was only thinking of the singletons themselves

#

that's a good point

late lion
#

I'm saying this from experience; I had a crash happening between scene loads on low memory mobile devices and it was because of this.

heady iris
#

i can believe it

#

i'm curious, how would you profile that?

fast belfry
late lion
fast belfry
#

So basically don't store references to assets or clear them (we're already doing that actually in lots of other places) and I should be fine with a static class

heady iris
#

Oh, neat. I haven't done too much with the profiler yet

#

other than just squinting at it and going "yeah that's my game's memory usage"

hello there , Im curious, what is the lightest data I can use on my voxel project for creating chunks? I am currently storing blocks as an Enum on a array (i.e BlockType.Stone)

#

Also, how do I know whats the size in kb or mb of my procedurally generated chunks?

heady iris
#

for an enum, it'll depend on the size of the datatype used to store it

#

iirc they're normally ints

glossy basin
glossy basin
heady iris
#

indeed, but i'm not sure if you can change the underlying type for an enum..

#

ah, you can

#

public enum Whatever : byte

glossy basin
#

interesting

somber nacelle
#

just be aware that unity probably won't be able to serialize enums that are not int-backed

#

but if you don't plan to have more than 256 different block types then byte will be the way to go. otherwise you'll need to use a larger type like int

glossy basin
#

this will probably stay below 255

#

and how do I measure how big my procedural mesh is in size?

#

Ah yes, ofc it was going to be as easy as just defining my enum with bytes

image.png
#

I think I already know where the issue is

heady iris
glossy basin
#

Im gonna need some help here

#

So apparently what causes that weird behaviour of deforming meshes so bad is the UV part of my mesh

#

I assume this is happening because the UV uses Int on its process

heady iris
#

wouldn't bad UVs just give you weird texture mapping

glossy basin
#

this is the code I use for assigning UVS

image.png
heady iris
#

perhaps it's mangling the mesh data

glossy basin
#

I essentially need to change int to byte right?

#

this is a Job

heady iris
#

where is the enum involved here?

glossy basin
#

this is before schedulling the job

heady iris
#

it shouldn't matter if it's a byte or an int; it'll get casted to an int if needed

#

and every byte value is representable as an int value

glossy basin
#

Hmmm, very weird

#

maybe the float2 causes a problem?

#

I am confused though, the code should work fine with this, weird thing is that it generates the data correctly if I decide to not use the uvs

near cave
#

are there any good alternative tutorials/videos for creating grid systems in unity that isnt code monkey? i find his videos very hard to follow

heady iris
glossy basin

#

that's even more mysterious

#

since that means it's not that the uv process is somehow mangling the mesh

glossy basin
#

yeah, I just comment this line mesh.SetUVs(0, UVmap); and it works

glossy basin
heady iris
#

wait, the UV order?

glossy basin

it should only distort the UV rather than modifiying the mesh itself

I have some textures with different discretized colors, for example the only red pixels will be (1,0,0,1) fully red, IE its easy to tell what color a pixel falls under. I want to count the number of pixels of each color in the texture and sum them in buckets, so i can tell if for example 50% of my texture is red, 20% yellow, 10% blue etc. Exact accuracy is not important, I just need generally which colors are there more of than other colors, and approximately how much more. Does anyone have suggestions on how to do this?

would it be easier to code a system where instead of having the player pickup items and store them in the inventory have them instead pickup items and bring them to the npc to complete a quest?

#

for example the code would be something like "if item is in hands while talking with npc then complete quest"

lean sail
#

Depends how advanced u want the inventory or the pickup to be

unborn flame
#

very simple

latent latch

if you dont want any inventory management then sure why not

just pickup and give

#

Then both are gonna be the same difficulty, and its just a matter of what u want in ur game

latent latch
#

if(condition == true)

unborn flame

lean sail

just a note, u dont need to check if a condition is true. the condition is a true or false statement

lean sail
unborn flame
#

currently i do but is really diffcult to manage

#

its a mess

lean sail
#

like interact with object -> object destroyed, bool on script set to true, then npc checks if bool

#

well an inventory system then would be way harder compared to just picking up an object and having it follow u, until reaching a trigger on the npc

lean sail
#

The 2 things you are comparing though really cannot be compared. If you have an inventory system, thats gonna be for multiple items (i hope). Then you go to the npc and turn it in.
Comparing that to just picking up an item, which only allows you to pickup one or two at a time is drastically different and heavily affects your gameplay even. Whether its a positive or negative effect depends on the game

How would you guys do an item system.

I mean let's say I have a 20 different swords that have different stats. 20 shields, 20 armors etc.

What is the most efficient way to manage this data and use it for my game?

I thought about making a json file where there would be all the items separated by category where all the stats are written. I can then just ask my game to parse the json for the stat I want.

Is it a good idea or is there better?

glossy basin
#

is this a good size for a procedural mesh considering how many vertices it has?

ah, well the inspector does not set it through the field and only the value, but what you can do is add some logic with OnValidate

That's what I've concluded on in the past. There's methods of using custom inspector drawers and attributes, but that's usually more effort than I'd usually want to put in.

You do call the base constructor first though and then the derived constructor in this case

Hello there, I was thinking about optimizing my game further, so , it runs at 390+ fps when idle, and goes down to a minimum of 170 fps when generating chunks while moving (this is barely noticeable, it goes down very slowly), so I am generating my chunks using job system and every time I create a chunk, my code creates multiple native arrays necesary for data, it looks like this

#

way too many arrays

image.png
#

so I was thinking of having this array on a separate scripts to instead of creating them every time, just resuse them from that script, clearing them before using them

#

So, is there a way to clear a native array without disposing it? does my thinking make any sense?

solemn raven
#

hi ,
is it possible to dynamically set the range value ?
for example :

[range(0,70)]

can i somehow when a bool foo is true , raise the max range to 100?

cosmic rain
#

No. At least not without some reflection trickery

#

Or a custom inspector/property drawer.

#

Could try this method, but you'll have two different values in your script which you need to check which you are reading from

#

You serialize a field to show in the inspector, not a property

#

[field: SerializeField] informs Unity to serialize the backing field of a property. If you write it as public float foo { get; private set; }, there will be a backing field created by the compiler, which is serialized. You never use the property.

thin aurora
#

I assume you want to trigger property code? There is no build in way to trigger a property instead, but you could add custom editor stuff to simulate it.

#

For example, I made this property drawer that triggers a method when the value was changed in the inspector:

[CustomPropertyDrawer(typeof(ObserveChangeAttribute))]
public class ObserveChangeAttributePropertyDrawer : PropertyDrawer
{
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        EditorGUI.BeginChangeCheck();
        EditorGUI.PropertyField(position, property, new GUIContent(property.displayName));
        if (!EditorGUI.EndChangeCheck() || !Application.isPlaying)
        {
            return;
        }

        var observeChangeAttribute = (base.attribute as ObserveChangeAttribute)!;
        var method = property
            .serializedObject
            .targetObject
            .GetType()
            .GetMethods(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
            .Where(x =>
                x.Name.ToLower() == observeChangeAttribute.Method.ToLower() &&
                x.GetParameters().Count() == 0)
                .FirstOrDefault();

        if (method == null)
        {
            var fieldName = base.fieldInfo.Name;
            throw new Exception($"Method \"{observeChangeAttribute.Method}\" not found whilst invoking change on \"{fieldName}\".");
        }

        method.Invoke(property.serializedObject.targetObject, null);
    }
}

Which could be called like this:

[SerializeField] [ObserveChange(nameof(OnFontSizeSettingsChange))] private int _fontSize = 12;
#

Note it's not very performant, but it's a way to validate settings, if you want.

#

how does bool check with Camera work? I've noticed it in a tutorial, they do

Camera myCamera
if (!myCamera) // ...

I can't find any info on that. Does it return false when myCamera is null or what?

dusk apex
granite nimbus
#

so it's just null check, alright

dusk apex
#

Well, there's not much to say.. it returns false when your variable is null.

granite nimbus
#

does it work on any class? I never knew it

#

any nullable type*

dusk apex
#

Depends if that class has got an overloaded operator for bool check

Not often used in c# since we only have null

#

So I just prefer to do if (myCamera == null) to differentiate with booleans, not that that ever matters.

granite nimbus
#

I guess I'll just stick to explicit == null for readability

thin aurora
#

Fun fact: Javascript ended up with the === to check if something is truly the value compared with, which == might not catch, because of this falsy stuff

Pretty sure nearly all components inherit Mono so it would be the same.

In the Editor, it could be not null but still throw an NRE - fake Unity null (I believe only if it's exposed to the editor, not sure)

granite nimbus
#

does it have to do with the weird overload of == operator, where basically the variable isn't null, but object doesn't exist

My interpretation of it - don't take it word for word

Hiya, stumbled onto a bit of an annoying issues. I use GUIDs on Scriptable Objects to find references for persistence. Like this:

        private void OnValidate()
        {
            if(string.IsNullOrEmpty(_guid))
                _guid = Guid.NewGuid().ToString();
            UnityEditor.EditorUtility.SetDirty(this);
        }

Problem occurs when I duplicate a scriptable object, then I have a duplicate GUID. How would I go around this issue?

dusk apex
#

It should be an Unique Identifier?

#

Meaning they would not be the same? (relative to assets)

heady iris
#

yes, the problem is that the serialized field is preserved when duplicating the asset

rain minnow
#

can't you create a new SO instead of duplicating it, or clear the string so it creates a new one?

alternative strategy: just use the asset's GUID! I'm trialing that for a save system for a solo project right now

#

i am a little concerned that I could shoot myself in the foot if I remove content and then decide to put it back later

#

but I guess I can just pluck the old assets (and corresponding metadata) from VCS

late bloom
#

Oh, why didnt I think of using that

heady iris
#

a compromise would be to just use the asset's GUID as the default

#

and then let the user override it

#

...but then you'd be back in the same boat: duplication would give a duplicate GUID

late bloom
#

I'm not super concerned about deletion here

#

Because it's an avatar for the player

heady iris
#

I was going to go grab an example

late bloom
#

And we have a fallback if none is found

heady iris
#

but i left my laptop in the car, oops

late bloom
#

So worst case, someone loses their selected avatar, but nothing game breaking

heady iris
#

i'm considering this for my save system, anywhere I need to serialize a reference to a SO
