And no longer anonymous

#

Same as storing an anonymous object in a variable, then it's just an object because it will need a type to be stored 😄

leaden ice
#

right the OP in the first example is not using the same delegate. They subscribed with an anonymous delegate and then stored a second anonymous delegate in a variable

heady iris
#

Ah! I misread it.

#

that makes more sense now

thin aurora
#

References can be very confusing to understand, but it's used more often than you might realise

heady iris
#

oh yeah, it makes perfect sense now that I'm done misreading it :p

#

if a type has no definition for equality, then you just get reference equality: are they literally the same object

#

and, thus, in this case, that didn't happen

thin aurora
#

And sadly there's not much you can compare delegates with

#

ᵘⁿˡᵉˢˢ ʸᵒᵘ ᵐᵃᵏᵉ ᵃⁿ ᵉˣᵖʳᵉˢˢⁱᵒⁿ ᵒᵘᵗ ᵒᶠ ᵗʰᵉᵐ

#

If I subcribe like this, Unity raises this error: Argument 2: cannot convert from 'VisualScripting.EventReceiver.OnEventRecivedDelegate' to 'System.Action<string>'... @thin aurora

leaden ice
thin aurora
#

I guess the compiler is not smart enough for it

leaden ice
#

sadly

thin aurora
#

So what PraetorBlue mentioned is the best solution

leaden ice
#

OCD moment - The correct spelling of the word is "received" 😆

thin aurora
#

Then you don't even need a seperate delegate declaration

This works. Thank you so much to both of you

what is the best way to check for an item besides tags?

#

To check if an item is an apple or a banana without using a tag for each fruit, for example

maybe a script with public enum type

how can i resize the grey box on the outside? or at least move the pivot point since its messing up my raycasts

#

if you are using a SpriteRenderer, the size of the grey box is the size of your sprite => it shows the transparent part of your png file

hey, what s the best way to do a player movement like this
rb.velocity = new Vector3(movement.x* speed, rb.velocity.y, movement.z* speed);

but make that it can bounce on bounciness Collider?

I'm trying to call a function on Click on a ui image, I have a public Action triggered on click via a EventTrigger.
My problem is that I register to the event in a for loop which loops through my clickable images (0-3) but when I click the value passed to my function is 4

    private void SetupRemoteButtons()
    {
        ScientistRemoteButton[] remoteButtons = remote.data.GetButtons();
        //buttonUIs = new ScientistRemoteButtonUI[remoteButtons.Length];
        for (int i = 0; i < remoteButtons.Length; i++)
        {
            //buttonUIs[i] = Instantiate(buttonPrefab, buttonsParent);
            buttonUIs[i].Setup(remoteButtons[i]);
            buttonUIs[i].OnButtonClicked += () => UseRemoteButton(i);
        }
    }
    private void UseRemoteButton(int buttonIndex)
    {
        if (FightScenesTimeManagement.IsPaused || FightSceneState.FightState != FightState.Fight) return;
        if (buttonIndex >= buttonUIs.Length || !buttonUIs[buttonIndex].IsSet) return;

        buttonUIs[buttonIndex].UseButton(allies.units);
    }

Changing the array size still sends the last value of i in this for loop (array length)

ayo does anyone know a fix for this, im new to unity and this seems like something pretty basic that should have an easy fix for it. I am essentially trying to create mutliple hitboxes for a unity game object and have one hitbox for physics and another acting as a hurt box that is larger and in a different shape that the original physics hitbox. I just cant find any way to declare another hitbox that doesnt mess up the other hitbox and I think that I am just missing some fundamental thing bc it seems like there should definitely be something basic for this

use layer
attach the collider(s) in child gameObject and assign it different layer

Does anyone know how I would get the asset name from a Serialized Property?

Hello guys, I would like to use Rider as a code editor but I have an issue:
My game is divided in 3 parts, a game "engine", a server, and the graphical part (with unity). The server and the game engine are in pure C# without unity. Both the server and unity part both need the game engine to function.

So I wanted to create a rider solution that contains the 3 projects, with the correct dependencies between them. The problem is that when I try to add projects to the generated .sln file, they disappear after some time, probably because this file is 100% handled by unity and shouldn't be modified.

What would be the best way to do that?

leaden ice
lean sail
#

The server could be split I guess

leaden ice
lean sail
#

Only the server could reliably be split up if it is just used to relay information. And even then if you try to add verification for anything, itll just be harder not having UnityEngine on top of it

#

I question if this is even a game

cursive talon
leaden ice
lean sail
#

I mean even then... unity doesnt force u to use physics

#

I think I saw something about stripping physics out if u dont need it entirely

cursive talon
#

I run the server without unity, and the server needs my game engine to run, so that's why my game engine must not be with unity

#

and that's why I dont write the engine in another language because I still want the graphics part to be in unity, and I want to use the same game engine library in the graphics part than in the server

lean sail
#

That's not a reason for why your game engine has to be outside unity.. what does unity even affect in that case?

#

Didnt u say its in c#?

#

Unity is not "another language"

cursive talon
#

no I mean the server runs without unity, so I kinda don't want it to use a library that requires unity

#

but are you saying it's a bad idea to have my server run outside of unity?

leaden ice
lean sail
#

A server is kinda vague, it can be used to just store information or actually connect players in a fps. If it's just to store information, then yea it doesnt really matter where you put it. If you're trying to connect players, theres gonna be challenges syncing UI without UnityEngine

cursive talon
#

no no lol I talked about another language because @leaden ice said it's probably better to create a game server in C++/Rust. My server runs in C# because it's using the same game engine than the unity game

lean sail
#

Ah my misunderstanding

cursive talon
#

basically it's a 1v1 game with a server handling everything

#

I kinda thought having the server without unityengine would make things easier, but maybe I'm wrong on that

heady iris
#

i don't see how that could possibly make it easier

lean sail
#

Well if you arent gonna sync any of the graphics, maybe it will work just the same..

#

Im kinda confused how you even have a game engine and server but no graphics at all, like how did this code come to be?

cursive talon
#

well the server only needs to synchronise the actions every player do, and in my game the actions are pretty simple, move a unit here, place a building there...

#

I only need graphics for the player, so I don't push anything graphic to the server

simple egret
#

So the server can be a plain old C# app, it has types that will pretty much map Unity types 1:1, like the stuff in System.Numerics

cursive talon
#

yea that's pretty much what it is

#

Only I can't add it to my rider's solution :S

simple egret
#

Yeah you'll have to separate it as Unity has full control over the whole solution

#

If you need to put both in version control, then pull the git root one folder up, and leave the Unity gitignore at the root of the unity project (now one folder down compared to the git root)

cursive talon
#

ah that's a good idea, I'll try that thank you

steady moat
cursive talon
#

well, hm.. that's a bit too late now 😅

#

at least I have a light weight server :D

cobalt gyro
#

how do i disable an input

cursive talon
simple egret
#

No because there will be two separate solution files *.sln, one for Unity to fully handle (your game), and another for your C# app (the server)

#

Pulling the git folder up just makes it so both solutions are included in the repository

#

There shouldn't be any sln file at the git root though

# 
.git/
game/
  game.sln
server/
  server.sln
cursive talon
#

and what if I wanted to do something like

.git/
main.sln
game/
  game.csproj
  game.sln
server/
  server.csproj

and add to main.sln all csproj I need?

#

is this possible?

simple egret
#

No, you can't make a solution include another solution that's nested

cursive talon
#

even if I just include the csproj?

simple egret
#

Yes because that will break Unity. Not sure if you can have a "shared project" between two solutions either, and even if you can, the Unity one requires references to Unity libs, including it into another solution may or may not cause serious referencing issues

#

I see nothing wrong with keeping two separate solutions within two separate folders

cursive talon
#

I would just be pretty convenient to have everything in one solution so I can see where everything is used, but I guess I'm too greedy

#

thanks for your help anyway

halcyon kayak
#

well its reasonable to split the game server in another project, maybe you want to dockerize it or something

..if you want something to compile in a different assembly you can use assembly definitions.. is this what you're trying to do?

i dont really understand what your goal is. if you want to split your business logic to make it look something like clean architecture, of course you could.. what is your goal?

cursive talon
simple egret
#

Assembly definitions is the Unity way of "creating a project in the solution". Outside of Unity you'd do that in VS, which allows you to control what references what.
But since Unity takes up a full solution by itself, you use asmdefs which are folder-based

fast aurora
#

Is it bad practice to do this?
public static AssetRegistry Instance;

#

In Java it's bad as it should be replaced with Dependency Injection

#

But i'm not completely sure about Unity/C#

simple egret
#

Outside of Unity you'd most likely use DI, like for ASP.NET websites where the DI framework is pre-installed. For Unity you'd have to install one

#

But having those things are pretty common yep, singleton pattern

halcyon kayak
soft shard
#

Another approach, if you dont want it to be static, could be to use a ScriptableObject to hold the data, and then the few classes that need access to that data can use a [SerializedField] so nothing outside can access it, or maybe a getter-only property, I guess it depends on your goals and design

lean sail
#

If it's a singleton, your actual instance probably shouldnt just be public

#

In reality, you would have to try to mess it up for something to go wrong. But better practice would be return the instance

Someone know why if I have this code attached to a weapon when I hit one enemy it does what is supposed but if I hit other different that is a copy it says that there is no skinnedmeshrenderer attached?

GameObject target = hit.transform.gameObject;
                    if (target.GetComponentInParent<EnemyTakeDamage>().hitPoints >= 1)
                    {
                        target.GetComponentInParent<EnemyTakeDamage>().Damage(1);

                    }
                    else if(target.GetComponentInParent<EnemyTakeDamage>().hitPoints <= 0)
                    {
                        smr = target.GetComponent<SkinnedMeshRenderer>();
                        Mesh bakedMesh = new Mesh();
                        smr.BakeMesh(bakedMesh);
                        Destroy(target.GetComponent<SkinnedMeshRenderer>());
                        target.AddComponent<MeshFilter>();
                        target.GetComponent<MeshFilter>().mesh = bakedMesh;
                        target.AddComponent<MeshRenderer>().material = Blanco;    
                        Slice(target);
                    }
#

Its like is Destroying before baking but only for the other enemy

#

and the skinnedmesh is their own so idk

How do you favor to keep your runtime objects?
Separate manager/controller classes or not?
For example items, buildings, plants, npcs, characters, enemies, etc. in a city building game
A manager class which contains some general methods like Add, Remove, GetAll, GetById

Theres this script on the Weapon, the enemies have a script EnemyManager each one but nothing related

Hello,
I'm trying to use the new Input System (Device -> ActionsAsset->PlayerInput Component->Script).

I use it like:

public void OnJump(InputAction.CallbackContext context)
{
    float inputJump = context.ReadValue<float>();
    if(context.performed) 
    {
        Vector2 inputVektor = new Vector2(0,0);
        inputVektor.y += inputJump;
        Vector3 movementVektor = new Vector3(inputVektor.x,inputVektor.y,0);
        transform.position = movementVektor * jumpSpeed * Time.deltaTime;
    }
}

My problem is, if I'm creating a Vector2 and Vector3 inside the function for jumping, it always resets the player to position 0,0 and then it adds the jump.

Sorry if its hard to read, I'm writing this on a smartphone but I can fix the text formatting later.

How can I create the vectors and create normal actions like jumping, moving etc. without always resetting the player to 0?
Thank you in advance!:)

If you need more information beyond if and what object is being dragged, then it will probably be in the OnDrag event

I have a bunch of characters that do an idle animation. I would like to use cycle offset to make the animation start at a different point in time. I created a parameter called "idleOffset" on the animator and set it to a random value between 0 & 1 in the Awake function. I can see that the parameter is indeed set to a random value for each character but still the idle animations all play at the same time. Anyone knows what I am doing wrong?
Idle is the default state, I don't know if that has anything to do with it

I'm not seeing where you're actually changing the position of any element when you're dragging

#

Generally, anything visual with dragging is just fluff. As soon as you're dragging something, the eventdata is populated with the object that's being 'dragged', which is then coupled with the OnDrop event

#

Should really read up on the IDragHandler docs and see how it's being done there

soft shard
#

I think im failing to understand something here... Why does this code log "90" then "270" back and forth, instead of "90" and "-90" back and forth? Is it just something with how rotation.eulerAngles is stored or am I just doing something dumb with the sign?

var r = transform.rotation.eulerAngles.y;
            if (someVec2.x < 0) { Debug.Log(r + " | " + Mathf.Abs(r)); r = -Mathf.Abs(r); }

I would imagine Mathf.Abs is always supposed to drop the sign, so even if I passed -90, it should return 90, but why is the log for both "r" and the math operation returning just 90 and 270 specifically?

eager yacht
#

-90 is 270. eulerAngles gives you values from 0 to 360

lean sail
#

You also likely shouldnt use Mathf.Abs because of that reason

soft shard
#

Is there another way to always flip the sign so -90 just becomes 90, and then -90 again instead of 270? Aside from maybe * -1 on the value, or would that produce the same problem? Do I have to do some kind of eulerAngles conversion or division on the 270 before applying it?

lean sail
#

If its negative just add 360

#

assuming its not below -360, itll work

soft shard
#

Hmm, alright ill play around with that, thanks btw

lean sail
#

If the value is way below -360, u can also do value % 360 then add 360 once if its still negative.
dont know if theres a function that already does this but i havent seen it yet..

#

you could also just do value % 360 regardless if its negative or not, then add 360 if its negative. Thatll ensure a value between 0 and 360 with the same correct angle everytime

I want to be able to access singletons in my code (managers/repositories etc) but I want to keep things ready for dependency injection, but not use it yet. I'm trying out creating a static class that stores a list of interface types and the object that derived from it. The singletons register adding their interfaces and themselves as the object to the list. Then other scripts can then use a Get to get a ref to the obect as the interface. So in the awake functions i can get the singleton by ServiceClass.Get<ITimeEvents>() to get the timecontroller singleton but with only access to the need events that are needed by the requesting class rather than the whole TimeController. Does this seem like a reasonable implementation?

What is a default material?

latent latch
#

If you don't select a material to add to an object you're rendering, it will use that instead

#

or it will instead apply that magenta (w/e color that is) error texture

raven basalt
#

Oh I see. How do I convert this default material into a materail that uses unity's shader instead, or do I have to remake the material from sratch?4

latent latch
#

right click into the asset menu and create a new material, then should should be able to change what shader to use on it and its settings

#

unity supplies a bunch of shaders already like you see there

heady iris
#

The problem is that the materials come from an asset.

#

You can't edit the material, because then you'd need to edit the original asset, or something

#

You can, however, duplicate the material

#

this'll give you an identical copy that is not part of an imported asset

#

all of the stuff in that fold-out menu were produced from that imported model

I use Rider for breakpoint debugging, and I'm noticing that if I disconnect the debugger (pressing the "stop" button), Rider won't be able to re-connect to Unity again. Any future connection attempt will show a "Waiting for target to get ready" message that never goes away.

My only surefire fix so far is to close both Unity and Rider. It's as if a resource (like a port) on one or both ends gets consumed by opening a debugging connection, and it never gets cleaned up.

Anyone else run into this and have any tips for a faster workaround? I'd be curious to understand what's going on under the hood here.

For context: I'm on MacOS 13.4, Rider 2023.1.2, Unity 2022.2.21f1

Not really sure where to put this, but I was wanting to have a ragdoll be dragged around like in the gif link. But I just want to be able to have the ragdoll be dragged around and still have it be a body, rather than it doing what it's doing now.
I've been trying to understand the documentation, looking up forums and tutorials but nothing I can find seems to be a solution.

I don't understand what "Still have it be a body" means

#

It looks like a body to me!

fierce orchid
#

I mean a body as in one that doesn't look spaghettified, like what its arm's doing

heady iris
#

sounds like the joints are stretching too far

#

what kinds of joints are you using here?

fierce orchid
#

Using CharacterJoints, the default when you use Unity's ragdoll creator. The "springs" are set to 0, so I'm not sure if that's the maximum (it says 0 means infinite but idk)

heady iris
#

you also have to set limits for how far they're allowed to move

fierce orchid
#

I've tried setting the limits to 0, 1, 1000 etc but doesn't seem to work

#

I've never done ragdoll physics before and the documentation and tutorials on it seem very limited. Whether or not I'm searching with the right keywords, not sure

cosmic rain
fierce orchid
#

Yeah I see that. What would I need to do to keep them locked together? I saw something about spring joints but I don't know if they'd provide a better alternative or not

cosmic rain
#

No clue. If anything, character joints should be more suitable imho. Never messed with them though.

lean sail
#

Regardless of what you do, the joints will try to snap back to its connected body if it goes too far past the limit

heady iris
#

did you use the Ragdoll Wizard?

fierce orchid
fierce orchid
lean sail
#

I dont believe character joints have a limit for how far they can move, although not too sure

lean sail
#

its quite a pain, im still fine tuning to see if i can fix it for my character

#

the problem is the linear limit spring has no max force, so im unsure if it really can be fixed

fierce orchid
#

I’m tempted to possibly try having a parent object and having that be dragged around instead, but I want to avoid that if I can

#

But yeah I’ll have a look into those joints and see if I can get them to lock in

lean sail
#

oh the video loaded, u were dragging it around

heady iris
#

I've gotten pretty good ragdolls with fast movements

#

in my case, I used a FixedJoint (or was it a ConfigurableJoint with everything set to a strict limit? gotta look) to attach the ragdoll to another character

lean sail
heady iris
#

it goes crazy if the enemy shoves the ragdoll into the wall

#

i need to turn off wall collisions while in that state..

lean sail
#

fixed joint works, i use it for grabbing although im also trying to do climbing which is become a problem

heady iris
#

i had a REAL fun time figuring out how to correctly align the ragdoll for the grab

lean sail
#

did you use a separate body? thats what i do

#

my character itself has no animations, it just copies them

heady iris
#

i'm using the PuppetMaster asset to manage enabling and disabling ragdolling

#

it creates a simplified copy of the armature

#

then it either drives the copy with the original (non-ragdolled) or the original with the copy (ragdolled)

fierce orchid
#

I’m guessing applying a rb.applyforce (or whatever it is) to the joint would be the solution?

lean sail
#

ah my character is perma ragdoll, an "active ragdoll" apparently is what its called

granite nimbus
#

will it cause any problems if I have a script who deletes itself?

heady iris

Destroy just signals to Unity that the Object should be destroyed

@lean sail @heady iris thanks for the help 🙂 I’ll see how I go with it

heady iris
granite nimbus
#

well, in fact I want to delete whole directory with scripts, metas and so on

heady iris
#

should still be ok, I guess

#

it'll kill the directory

#

unity will then recompile

lean sail
#

it should be fine but once its compiled i dont know how you'll do that

#

i mean once built

heady iris
#

well, yes, I am assuming it recompiles here :p

granite nimbus
#

it's just an editor script who is meant to be run exactly once and then get deleted. and I didn't want to bother user with it

lean sail
#

just curious what you're even doing? seems like everytime u are up to something very niche lol

#

if its a 1 time script that u dont want after it runs, why not just run it and delete it yourself

granite nimbus
#

it has config SO, and you click one button and it converts everything automatically - renames folders, removes unneeded stuff, renames asmdefs, etc

cosmic rain
#

What if the user might need to run it again?

lean sail
#

forget the user, what if you want to run it again lol

granite nimbus
#

🤔 🙃

lean sail
#

the only time ive heard of or even thought of self deleting scripts was in malicious programs

granite nimbus
#

I'm not really sure if I need that, but I just want to

#

or actually maybe you're right, I just won't delete it

#

user will delete it if they don't need it anymore

cosmic rain
#

Your code gets compiled into an assembly and run from it. The script is just a text file.

granite nimbus
heady iris
#

critically, the script file on your computer doesn't really matter

#

it's been compiled already

#

and everything goes away when you recompile

granite nimbus
heady iris
#

yes, because otherwise, you could discover that your code is actually invalid

cosmic rain
#

Yes. But I don't think there's any framework/engine or compiler that executes the code directly from the code file.

granite nimbus
#

alright, sorry for confusion then

heady iris
#

it would be very weird if you got a compile error only when you tried to run the code

granite nimbus

That doesn't prevent you from running the compiler.🤷‍♂️

And what if you didn't use an ide?

heady iris
granite nimbus
heady iris
#

you couldn't compile your project in the first place

#

it simply Would Not Run

#

JITing does not mean you lex and parse your code at runtime

#

it's just the just-in-time generation of machine code

cosmic rain
# granite nimbus ❓

You could write your code in notepad and launch the compiler from a command prompt 🤷‍♂️

heady iris
#

you may be mixing that up with dynamically parsing and executing C#

#

which you can do (scary)

heady iris
granite nimbus
#

interesting

heady iris
#

i forget what the namespace/class is

#

someone brought it up a few days ago (scary)

granite nimbus
#

where the IL actually lives in project?

cosmic rain
#

You can do it in VS without anything extra

#

It's the C# interactive window

granite nimbus
#

nvm it's Library/ScriptAssemblies it seems

#

curious what will happen if I delete Library at runtime awkwardsweat

cosmic rain
#

At best it would not need to load a library(since they're loaded into RAM), so nothing would happen.

#

But I think the OS might block the loaded files from being deleted.

granite nimbus
#

anyway I will never need to do that xD

#

was just curious

heady iris
#

Windows loves doing that

#

On Linux, deleting the files would do nothing if there was still an open handle

Heya, bit curious about something, I wanted to test that new Netcode for GameObjects thingie for a WebGL game, but I remember hearing that it wasn't supported, but on the documentation i can find nothing about that. I also heard though that there are alternatives? Do any of you know about any of this?

leaden ice
granite nimbus
#

what is the difference between doing

#if MY_CONDITION
// stuff
#endif

and

[Conditional("MY_CONDITION")]
// stuff

other than Conditional is way less universal? am I missing something?

fervent furnace
#

can the attribute use inside a method? i think it cannot since it doesnt specific where to end

granite nimbus
#

and why would one use this attribute when you have #if

lean sail
#

[Conditional] doesnt not compile the method if its not needed

#

i think..

fervent furnace
quartz folio
#

and not all things can have Conditional applied to them

#

Only the calls are stripped

granite nimbus
#

🤔

granite nimbus
#

as far as I understood it

quartz folio
#

Yes

granite nimbus
#

makes sense

quartz folio
#

I even have a library that uses both, Conditional to strip the calls to the methods, and #if to strip the methods completely

granite nimbus
knotty venture
#

how can i make a level

#

like a new level i already have one how do i make another

lean sail
#

not really a code question, but right click in your project files. Create > Scene

knotty venture
#

so i have to redo everything again

gray thunder
#

well u want it to be a different level no?

thin aurora
#

Did you expect anything in particular to be in the scene?

open shard
#

I have a bunch of characters that do an idle animation. I would like to use cycle offset to make the animation start at a different point in time. I created a parameter called "idleOffset" on the animator and set it to a random value between 0 & 1 in the Awake function. I can see that the parameter is indeed set to a random value for each character but still the idle animations all play at the same time. Anyone knows what I am doing wrong?
Idle is the default state, I don't know if that has anything to do with it

deft timber
#

or you are just setting it to a random value but that's it

open shard
knotty venture
#

how do i make it go

#

it keeps getting stuck

#

in 1 place

prime sinew
knotty venture
#

i have code that it shoots

prime sinew
#

okay, what about making it go

#

i'm assuming by go you mean move

knotty venture
#

yea that the bullet goes forward

#

and not staying in place

prime sinew
#

okay, how about showing any code where you tried to make the bullet move

knotty venture

can you show the inspector of the object with this script

#

and are there any errors in the console?

knotty venture
#

there are no errors

#

at least no red errors

prime sinew
knotty venture
prime sinew
#

try increasing the bulletForce to like.. 200

knotty venture
#

that did nothing

#

xd

prime sinew
#

the bullet is spawning, right?

knotty venture
#

yea

#

it is

prime sinew
#

can you try changing this
bulletRb.AddForce(firePoint.forward * bulletForce, ForceMode.Impulse);
to
bulletRb.AddForce(Vector3.forward * bulletForce, ForceMode.Impulse);

#

just temporarily. testing

knotty venture
#

sure sur

#

that also did not move it

prime sinew
#

are you able to record a video of what happens?

#

also select the bullet in the hierarchy once it spawns so I can see the inspector

knotty venture
#

im not that good at english xd

prime sinew

show the bullet inspector please

knotty venture
prime sinew

the full thing

knotty venture

this also makes it crash my game

you.. destroy bullet or bulletPrefab anywhere?

knotty venture

uhm no i don't know how that works

im a bit new xd

#

is it just Gameobject.Bullet.DestroyObject

knotty venture
knotty venture
prime sinew
#

i dont see Destroy anywhere

knotty venture
#

yea true

#

i dont know how to xd

#

i tried before but it doesnt work

#

so i have to do

#

Destroy(gameObject);

#

or that with the bullet name

prime sinew
#

you don't

#

never mind. i dont know why you have that error, and not sure if it's got anything to do with your bullet not moving

knotty venture
#

same i legit don't know haha

prime sinew
#

show me your Bullet script?

knotty venture

oki

prime sinew
knotty venture
#

uhm

#

the what xd

prime sinew
#

the bullet prefab

prime sinew
#

did you drag something from the scene, or from the project window

knotty venture
#

you mean this

prime sinew
#

is that the one you drag into the bulletPrefab variable

#

you could be making it a Prefab. It shouldn't be in your scene

knotty venture
#

idk what prefab is man

prime sinew
#

otherwise it's going to call Destroy(gameObject, lifetime); from Start

#

then you should have started with some unity basics

#

https://learn.unity.com/tutorial/prefabs-e

Unity Learn
Prefabs - Unity Learn

Prefabs are a special type of component that allows fully configured GameObjects to be saved in the Project for reuse. These assets can then be shared between scenes, or even other projects without having to be configured again. In this tutorial, you will learn about Prefabs and how to create and use them.

knotty venture
#

true but i came this far without knowing what it is xd

prime sinew
#

go through that first

#

you need to learn it. that's basic stuff

#

that's why you're getting the error

#

once you've made a bullet prefab, you set the speed in its inspector to 200, then you see if it makes a difference

#

funny how you call it bulletPrefab, but it's not a prefab

knotty venture
#

sure

#

thnxx

prime sinew
#

maybe this will make it clearer

#

since the text one might be hard for you to understand

I know how to achieve blending two textures using shaders, but does anyone have a link to a tutorial that explains how to blend two textures using some sort of input? Like say I want to paint a dirt path on the ground, how would I achieve that(assuming I'm not using terrain)

heady iris
#

Note that I'm not sure how you'd do the painting part -- I've done similar things before, but not actually implemented a painting tool

#

(it was automated as part of level generation)

#

I'd make a shader graph with three Texture2D properties.

#

Two would be the input textures, and the third would be the mask.

#

Sample the two textures normally, then mix them with a Lerp node. The t input on that node would come from the mask texture

radiant marten
#

mmm

#

yeah that makes sense, but I guess I'd have to find some way to paint onto the mask

#

and it'd have to translate onto the uv properly

static matrix
#

is it possible to regulate an object to a prefab? Like just tell it "Hey, from now on, follow all the rules of this prefab"

#

Like if you make multiple objects, then do the prefab

heady iris
#

no, you can't retroactively make something a prefab instance

#

other than by making the prefab from it

static matrix
#

Tragic

#

I'll have to remember to do that in the future

#

time for my file system to become even more unavigable

heady iris
static matrix
#

you dont want to know

heady iris
#

shame, shame

static matrix
#

my Documents folder could kill someone with OCD

#

its on par with terraria chests

radiant marten
#

could you not make a one-time editor script that scans through all the game objects and instantiates prefabs and deletes the game object?

static matrix
#

you can make editor scripts????

radiant marten
static matrix
#

I will have to employ these

#

thank you

heady iris
#

yeah, i had that thought

static matrix
#

I could make an entire game in just the editor then

#

although that would be lame

radiant marten
#

can also do

#

since I think it'd a feature more fitting for the menu

im making a card game and obviously want each card to function differently but I dont know if I should make a script for each card or use scriptable objects somehow

#

does anyone have any tips

trim rivet
#

Anyone good at math? I'm trying to fill a three dimensional matrix evenly with nodes... so I iterate through say 16 positions that I try to get via this script... but the Z value I cannot figure out how to retrieve, based on the input parameters...

image.png
heady iris
kind wolf
#

yea thats the problem

heady iris
#

4096 = 16*16*16-1

kind wolf
#

if i use scriptable objects i cant really write specific code

cold egret
kind wolf
#

but wouldnt having a lot of card scripts stored in memory be bad for performance?

trim rivet
heady iris
#

no

kind wolf
#

im planning on having a lot of cards

heady iris
heady iris
#

you have roughly the right idea here

trim rivet
#

I believe so... it seems to be working fine for the x and y values I believe 🤔

heady iris
#

you don't have a Floor on the calculation for Z

#

sounds odd

tawny mountain
fervent furnace
#

for access 1d flatten array with index i1,i2,i3.....
(i1*size(i2*i3*i4*...)+i2*size(i3*i4*...)*i3*sizeof(i4*...)*....)

kind wolf
#

like art and stuff

#

i cant just insert them in the inspector

trim rivet
#

I feel like I have tried every possible operation

heady iris
#

maybe you should stop and think about how the math works...

#

suppose we're doing a 10x10x10 cube

#

i is the index

#

when i=1, you get [1,0,0]

#

Y and Z are both at zero right now

#

Oh, nodesPerSide is an int, so you were already getting a floored result

#

i see

#

but let's go through the example anyway

#

when i=10, you get [0, 0, 1]

X = i % 10
Y = i / 100
Z = i / 10

#

that sounds reasonable

#

What is the problem?

tawny mountain
heady iris
#

I guess you also need to take Z modulo 10

#

so that when you hit i=100, you get [0, 1, 0]

#

rather than [0, 1, 10]

fervent furnace
#

(i1*size(i2*i3*i4*...)+i2*size(i3*i4*...)*i3*sizeof(i4*...)*....)
i1=index/size(i2*i3*i4*...)
i2=index/size(i3*i4*...)-i1*size(i2)
i3=index/sizeof(i4*...)-i1*sizeof(i2*i3)-i2*sizeof(i3)
how you get back all the indice from a flattened index

yo!
How do I use initiated objects on another if statement?

image.png
#

where the else is I want to destroy the instantiated object

potent sleet
#

its local to that if statement

vestal summit
#

yeah

#

ik

#

is there any way to destroy the instantiated object on the else statement??

grim maple
#

its instantiated in the if statement, how could you expect to destroy it in the else, if it hasn't been created yet

potent sleet
potent sleet
vestal summit
#

var

#

ok

#

I'll do that

#

well I knew that it wasn't making any sence

#

please don't tell me the obvious

potent sleet
vestal summit
#

oh wait

#

not like private var name?

potent sleet
#

you can't do private var

#

you need to specifiy a type

vestal summit
potent sleet
#

var is for local memember

fervent furnace
#

you can try goto and go into the else statement but the normal contrl flow is execute either one of these two group of statements.....

vestal summit
#

I haven't used var that much before so I'll go look it up a little

potent sleet
#

but the object wouldn't exits in the else statement anyway so why bother

thin aurora
#

Considering I don't see it being defined anywhere, I assume it's class-scoped

vestal summit
#

sorry I forgot about that

#

I used GameObject on that

thin aurora
#

Yes so you can just use it anywhere in the class

#

The question is if you assigned it at that point

#

Otherwise it will be null

#

So you need to make sure of that

tawny mountain
vestal summit
potent sleet
#

if it's null you cant destroy it

grim maple
#

you can't call Destroy() on a null object

vestal summit
#

the weaponBelt thing is a gameobject

#

a prefab

potent sleet
#

yes we see that

#

if you dont assign it prior to the else you're just gonna get a NRE

vestal summit
vestal summit
#

so how do I do that

#

var?

potent sleet
#

we don't know why you are wanting to destroy this in the first place

#

that's more important

#

as this smells like XY issue

vestal summit
#

ok I'll explain the code a little

#

this code is part of an inventory I made. So the if (slot.ItemData != null) is the slot it self and checks if it's not a null

#

on the else statement

#

it is null

#

so if there's no item in the slot. It should delete the belt instantiated object

#

that's what I want

#

idk if that helped

fervent furnace
#

but you instantiate it if itemdata is not null
so if it is null then nothing will be created

tawny mountain
#

I must be asking in the wrong thread I guess

vestal summit
#

I need to get deleted

#

did you read? :P

#

the object gets added

fervent furnace
#

@tawny mountain i see your code since i havent use ondrag before but your code seem works

vestal summit
#

what I'm asking is I want to somehow use the instanted object in the else statement

#

idk why]

#

which is why I'm asking

fervent furnace
#

you may need to think a new and clear control flow of your program....

vestal summit
#

someone said to use var with MyType. I don't really understand what that means. And unity doesn't have a post anything about var

potent sleet
fervent furnace
#

if nothing is created then nothing needed to be destroyed...

vestal summit
#

I'll give the full code

potent sleet
#

if you want... just add a check

#

if(belt != null) Destroy(belt)

vestal summit
#

where can I post it?

fervent furnace

I mean I did try

potent sleet
vestal summit
#

is using Gameobject belt correct?

potent sleet
#

it's fine, but you need to check it's not null first before attempt to destroy

vestal summit
potent sleet
#

not really

vestal summit
#

and it does check if it's null or not null

#

just tested it with print

potent sleet
#

it checks for ItemData in slot

#

not belt

vestal summit
vestal summit
potent sleet
#

you kinda do

vestal summit
#

why?

potent sleet

cause if belt is null then you cannot destroy it

#

and get error

if I've done something like this it would work

of course I don't want it to be on a timer

if nothing is printed on console, that means nothing call it back

but it's called multiple time. you can only remove once

vestal summit

kinda makes sence why you said to check in the else statement if the belt is not null. There could be an error in the instantiation

potent sleet

that happens only once

I want to implement a stat tracker into my game. I'm not sure if I should make this a singleton MonoBehaviour (maybe I DDOL it), or if it should just be a lazily-initialized POCO

#

Any opinions?

#

It will be tracking some stuff that changes very infrequently (e.g. number of times you've started a game)

potent sleet
heady iris
#

and also some very frequent stuff (footsteps taken)

gray mural
heady iris
#

I'll probably write the data out to a JSON file on quit and on a regular basis

vestal summit

ah yeah, maybe

potent sleet
#

POCO
no need for mono tbh

tawny mountain
potent sleet
tawny mountain
#

Neither the remove nor the debug

twin hull
#

@gray mural you don't have an option of setting it through script instead of rich text?

heady iris
#

just the runtime object

fervent furnace
#

try debug if the method is called

heady iris
#

actually, can I just register a method to run on application start? I remember seeing that...

I just need to make sure I load the saved data before trying to use it

ha

potent sleet

ah fuck

heady iris
#

jinx

twin hull
potent sleet
#

lol

heady iris
#

yeah, this is what I was remembering

#

so I'll deserialize the data at launch, then periodically serialize it

#

so that if you get mad at my game and shoot your computer, you won't lose too much data

twin hull
#

imagine having the ability to read documentation instead of trusting google and chatGPT

gray mural
#

but finding documentations is quite difficult

gray mural

in this case it did though

swift comet
#

Thats why a unity page exists with a search function xD

heady iris
knotty sun
#

and you didn't even use the unity keyword which I do not understand

heady iris
#

rather than asking a spam machine to hallucinate an answer

gray mural
knotty sun
#

impossible

gray mural
#

though it should be nice to combine chat gpt with documentations

heady iris
#

this is very different from it knowing things

#

I can convince you that I know how to draw, but I cannot draw

potent sleet
gray mural
knotty sun
#

in which case it is worse than useless

heady iris
#

i really cannot understand the appeal here

#

i would simply not use the Spam Machine

fervent furnace
#

if the method not being called then you may missing some important setups probably a eventsystem on scene, and you need to ask others for more further helps, i didnt use it @tawny mountain

tawny mountain
#

I have an event system in the hierarchy

swift comet
#

I think GPT is quite useful, I see a lot of appeal for it writting code when it involves small snippets, it atleast gets you on the right track really fast. But only is good if you already know what you kinda want.

vestal summit
#

fixed the problem some how @potent sleet

image.png
heady iris
#

I figure out what I want, and then I write it

swift comet
#

Thats naive way of thinking but ok

heady iris
#

🤔

potent sleet
#

yes let's not argue over a hammer/ screwdriver again xD

potent sleet
vestal summit
#

I just figured out another way to Destroy an object

#

I did realise that it was instantiating a lot of objects for some reason so I just did childCount which gave me an idea to just delete all children in the parent

#

idk why I didn't come up with that

Chaning Alpha Parameter in TMP_InputField

wintry crescent
#

is rigidbody.angularVelocity local rotation, or world rotation?

heady iris
#

velocity is world-space, so I'd expect the same for angularVelocity!

wintry crescent
#

ah, damn
then I have a problem
I'm adding torque to a weirdly rotated object. Is there a way to get how much angular velocity the object already has, in the same "direction" that the torque would increase? I'm looking for a float.

I hope it's not too confusing

# potent sleet what isn't working about it?

Ok , I figured something out , maybe you can help get me to the finish line now... The methods are called when I try dragging the item slot , not when I try dragging the item from the item slot.. so I'll need to remove it from the item class instead of the slot class

One last question , what if I wanted items to start in the item slot? I can put them there by default , in the editor , but can I do that through code?

Yes

put the anchordposition to be item slot location

    }

this feels like it should work, but it doesn't

#

nothing is triggered

#

let me try something else maybe

#

its probably a parenting issue

lean sail
#

Parenting shouldnt effect collision

well if the collider is in the child, but the script is in the parent

from a script attached to a ParticleSystem
How do I attatch a script to the system istelf, or do they just mean the same object

dreamy dawn
#

when I copy paste my prefab only the last pasted prefab uses the script attached to it

#

Im using GameObject.Find(), is that the issue?

leaden ice
#

what does it mean for the prefab to "use" a script?

wintry crescent
#

Does field:SerializeField only work in some unity versions? I swear it worked at some point

leaden ice

    [field:SerializeField]
    private float maxWheelTurns

        get
        {
            return ((_rotationRangeDeg / 2f) / 360f);
        }
        set
        {
            _rotationRangeDeg = value * 2f * 360f;
        }
    }

my code, for reference

#

I tried both with property and with field

leaden ice
#

it only works for auto properties

wintry crescent
twin hull
#

yep.

leaden ice
#

if you are providing a custom implementation for the property, it won't work, because there is nothing for the attribute to target

#

with auto properties the attribute targets the auto generated backing field for the property

#

with a custom implemented property, there is no such thing

leaden ice
#

since that's your backing field

twin hull
#

tl;dr: get;set; is exact same as get { return hiddenField; } set { hiddenField = value; } private var hiddenField;

wintry crescent
leaden ice
# 
[field: SerializeField]
public int X { get; set; }```
is like:
```cs
[SerializeField]
int _x;

public int X {
  get => _x;
  set => _x = value;
}```

ShowNativeProperty doesn't seem to work

dreamy dawn

Idk how to explain it

leaden ice
dreamy dawn
#

But the other prefabs dont run the script

leaden ice
#

and how you are verifying that it only runs on one of them

#

also please note the difference between a prefab and a prefab instance in a scene

dreamy dawn
#

Alright

#

I verify that when the code starts nothing happens. No movement. No nothing

lean sail
#

Thanks for verifying

leaden ice
#

it may be running and simply having an unexpected effect, or some other code is reversing its effect or whatever

#

Also please show the code

dreamy dawn
#

Impossible but lets take a look

leaden ice
#

impossible
bold claim

dreamy dawn
#

impossible

wintry crescent
dreamy dawn
#

Okay it might be possible

#

it printed the started

leaden ice
#

So your assertion that only one is running is false

dreamy dawn
#

2 copies

#

2 started

leaden ice
#

So the problem is not that it's not running.

You need to investigatet further

Heyy, looking to create an object generator in a most performance effective way
Is there any way i can improve this code?

    GameObject stone = Instantiate(stoneObj, transform.position, Random.rotation);
    cooldown = false;
}

either get rid of update or get rid of the coroutine

you only need one or the other

      yield return new WaitForSeconds(5);

      // spawning
      GameObject stone = Instantiate(stoneObj, transform.position, Random.rotation);

When you want to repeat code, that's what loops are for. You only need the one coroutine

if I create a script to store data and place that on prefabs. Is referencing that script from the prefab mechanically similar to using scriptable objects?

heady iris
#

scriptable objects do not have to exist on an object

#

your MonoBehaviour does

topaz ocean
#

I mean in terms of memory efficiency

lean sail
#

spawning a bunch of those prefabs would make more data than all of them referencing 1 SO

topaz ocean
#

The idea is that I wouldnt be spawning the prefab

#

but using this script as an accessor for data related to the prefab

lean sail
#

in terms of memory, it really wont matter. I guess the prefabs themselves might be more than an SO asset

#

itll be like trying to save less than a mb of memory

topaz ocean
#

I guess im more concerned about whats more professional. Since I am about to make a LOT of object types. And the possibility of needing to redo it later on is a bit intimidating.

lean sail
#

id definitely just go with SO rather than try and recreate data containers

#

because all those data containers u will be setting up manually as prefabs. If you have to go back and change something thats a ton of manual work

#

with an SO at least u can mass create them

topaz ocean
#

Part of whats making the decision so difficult is that there are advantages provided by the prefab editor which could be beneficial in the long run. Like having to set up the dimensional parameters for an object can be a bit iffy, but I could make an editor to have that process be a lot more intuitive.

#

would it be hard to access the script on the prefab if I wanted a certain type to be selectable from within the game?

lean sail
#

i dont really know what your intending to use these prefabs for, it sounds like you want more than just data to be contained in them

#

i just assumed u had an empty game object with a script on it

Hi yall I've got some unusual problem with Sprite Shapes. So basically i try to spawn bunch of collectible items using RaycastHit2D, but they end up being on wrong positions. It happens because Sprite Shapes for some reason don't update their colliders when they are off camera. When im observing gameplay through scene mode all Sprite Shapes update their colliders corectly because i see them. The problem Is that i have to spawn them ahead of camera because that would be weird for collectibles to pop into existence in front of player right 😛 ?

spawnProblem.png
topaz ocean
# lean sail i just assumed u had an empty game object with a script on it

Well, for an example in my context I want to be able to have a configurable vehicle. Where I have a script that defines the parameters for the chassis, like the wheel size, wheel base, track width, etc. So that that data is tied to the prefab that houses the resources for the object. That way if you swap from a car chassis to a truck chassis, it will already know how to rearrange the parts to accommodate it.

lean sail
#

still sounds like SO would just be better in that case

wispy wolf
swift falcon
#

@wispy wolf mmmm im not sure, but its weird that it adjusts only when its seen

topaz ocean
wispy wolf
swift falcon
#

@wispy wolf wouldn't have bothered any of y'all guys 😛 if i hadn't tried lots of stuff

#

@wispy wolf I have thought about manually adjusting collider to sprite shape but there's also a problem... Sprite Shape uses splines and polygon collider2d uses list of x,y Vector2s. Have you got any experience with splines?

lean sail
# topaz ocean What are the advantages?

really just try it, you're recreating an SO by using these prefabs with a script on it purely for containing data. Editing these scripts are going to be way harder

swift falcon
#

Or maybe should i ask this way. Does anybody know how to get [x,y] points from splines in a manner that for eg. polygon collider 2d has them stored? If i could only figure that out i would be able to copy these points and manually update collider. I'd be VERY thankful.

Yo. I've got a problem with projecting a webcam stream onto a texture. I can see video input projected onto a plane, but it stutters every 1-1.5 seconds. Everytime it stutters it seems like the light gets readjusted so I suspect its autofocus. I used webCamTexture.autoFocusPoint = null; but it didnt change anything. Its a shitty old tracer webcam, but when I tested it in discord and the windwos camera app, the stuttering didnt appear. Has anyone encountered this problem?

@swift falcon there was a method to rebuild collider at runtime, they were even showing it in their demo video

swift falcon

@twin hull where?

twin hull
#

fuck if i know ahaha, i'll try to find it i guess

steady moat
#

Both, I doubt that you will have a stateless car.

topaz ocean
#

what do you mean by stateless

steady moat
#

There is no value that change

topaz ocean
#

The way Im approaching vehicle simulation is to write scripts that build physics systems from rigidbodies and joints. These scripts are that which handle the state of the object.

#

I just need a definition for the vehicle's values that I can slot in the "customization menu"

steady moat
lean sail
swift falcon
#

@twin hull ohhhh i think u just helped me i found something on Google thx 😄

steady moat
#

An SO should be stateless.

topaz ocean
#

I feel like you misunderstood. I have an object that handles the state already, it is the same object which builds the part. What that needs is a definition to be fed, which is planned to be done so through whatever means of definition I choose. Currently prefabs seem appealing since they make it easy to assign components from a variant of the FBX prefab, I could even add an editor with gizmos to better visualize the properties. My primary concern is how easily accessible these prefab scripts would be from within the game.

lean sail
#

I dont see how assigning components from a variant is any easier than just having an SO for the tire

#

That SO can store a reference for what object to spawn. Not the object in the world

topaz ocean
#

huh? the SO wouldnt have a specific object to spawn, it has the instructions for how to build something.

lean sail
#

Accessibility shouldnt be an issue regardless of how u code it, the issue comes when you want to make a change and you have to edit a bunch of prefabs rather than an SO

topaz ocean
#

I would only need to edit the prefab relevant to the part. I dont se how having a "heavy strut" and "light strut" scriptable object is significantly different from having them as prefabs that I enter to edit the scripts of.

lean sail
#

What do you mean instructions to build something

topaz ocean
#

Currently, I am trying to work with scriptable objects. I store the skinned mesh renderer that comes with my FBX prefab so I can assign it to one of the objects that my system generates.

steady moat
steady moat
#

Definition is most of the time responsable to construct its world representation.

topaz ocean
#

Im not storing the prefab

#

im storing the renderer on it.

#

if I stored a prefab with multiple renders I would have no way to access them correctly.

steady moat
#

An FBX is a prefab

topaz ocean
#

yes

steady moat
#

So you are storing a prefab

topaz ocean
#

no

#

I am storing the skinned mesh renderer component, that is on the prefab

steady moat
#

Bad idea.

lean sail
#

are u not trying to spawn the whole object? can you describe what you're this is actually for in the game because i still dont know what "instructions to build something" means in your game

steady moat
#

Store the prefab and get the renderer.

#

But you should spawn the whole object

#

Ideally, divide your object in multiple part.

#

Maybe you exported one FBX with everything.

#

But divide everything in multiple GameObject.

topaz ocean
#

my parts often need substantial modification before they can be represented properly, if I simply instantiated my prefabs im risking a frame where everything looks wrong.

steady moat
#

Find an alternate solution.

topaz ocean
#

I need to break up their construction into the creation of objects on which to place components. There are serious physics issues with scaling physics components.

#

I am animating my parts via physics, so I cant simply put a rigidbody on a bone. I need that bone to be a child object of the rigidbody.

#

thus I need to assemble the whole part manually.

steady moat
#

I do the samething. I have weapon which need to be link with SkinnedMesh of the player.

#

I still use prefab.

topaz ocean
#

does your weapon function physically with numerous joints

steady moat
#

it cahnge nothing, it could as well be.

#

You can do complex setup ame with using prefab.

#

Anyway, you want SO for your orginal issue.

#

For sure.

topaz ocean
#

how do you propose I properly scale the strength of a spring if its just a prefab I instantiate...

lean sail
#

what do you mean scale the strength of the spring?

#

you havent really described much of what your game is actually doing, so we dont know what effect this is supposed to have

topaz ocean
#

this is a part of one of the scripts in charge of "Generating" my part, its dependent on variables that come from the vehicle data. The idea is that it handles the building, rebuilding, and state of the part it represents.

I feel like it would be painfully more difficult to manually make prefabs for every part where I assign the rigidbodies, colliders, renderers, etc, one by one.
Such probably would be the case if dealing with components post-creation wasnt so finnicky.

What I am curious about is whether it would be practical to make scripts that I can assign to a variant of the imported FBX prefab, where I can define which properties to use in order to guide generation.

example.png
#

If I instantiate a strut with rigid bodies already on it, that isnt going to behave as I expect if I try to set its transform properties.

lean sail
#

im asking about what this effect is in your game. What is the goal in your game itself that the user will see happen?

topaz ocean
#

Well, ideally each vehicle is defined by some collection of data which says which parts it is made of. Those parts are read as instructions when the game is tasked with building the user's vehicle.

#

The parts the user selects will be the SOs or prefab scripts.

#

as the developer, I feel that I could make the process of setting up this data easier by doing it from inside of the prefab of the part, where I can have easy access to the prefab's components for assignment.

lean sail
#

You can get the same result by doing it as you are, but whatever component you store on that prefab, you can store that in an SO

#

if you feel its more accessible by making it a prefab then go for it. It will just be way more annoying when you want to change something

topaz ocean
#

what would be difficult to change though

lean sail
#

that depends on your design and how you choose to implement things. Kinda hard to make an example thats related to what your system is. I imagine if you want the user to select between different materials though, you'll have to make a new prefab for every single tire variation of materials

#

you could code it in a way where u dont do that, but with SO you can just store the list of materials already

finite coral
lean sail
topaz ocean
#

Yeah, I have thought about the varying materials possibility, I just thought I would do that similarly to tuning, where paint jobs arent vehicle-specific, and would likely be applied after the base material.

lean sail
#

yea so you could code it where it isnt an issue, but that list of materials is going to have to be stored somewhere else then. Where? well either another prefab, or another script

#

I cant really say itll be bad because you could design it really nicely, but at the end of the day scriptable objects could just store it by itself

topaz ocean
#

Plus, when I set the wheelbase and track width, I really have no idea what thats going to look like when it generates, so I thought I could make an editor with handles that render to assist.

#

that way it renders inside of the prefab n stuff.

leaden ice
#

It would seem to indicate your JSON payload is not correct somehow

#

You sure JsonUtility can handle the type you gave it? Check the actual JSON string it produced vs the API spec.

steady moat
# topaz ocean But I am in the same boat, the only thing stopping me from powering forward with...

You do not need to use a prefab, it just that if you want to use a prefab, you should not reference a component inside it. You could easly, just make a function on your SO that edit your car. Adjusting whatever setting it needs.

public class MyPiece : ScriptableObject {
  [SerializeField]
  private GameObject tire;

  [SerializeField]
  private float friction;

  public void Assign(Car car) {
     car.SetTire(tire)
     car.SetFriction(friction)
  }
}
#

Also, you can make an Editor for a SO.

twin hull
topaz ocean
steady moat
topaz ocean
#

what location

steady moat
#

visualize where parts would be compared to the vehicle's body

topaz ocean
#

ah

steady moat
#

You will need an object in this instance, that would be the actual part. (Prefab)
The SO would be the concept of the part.

Think of this as a class versus an instance of a class.

#

You can also see this as the following:
You want to buy a fish in the market. In this sentence, the fish is a SO. It is stateless. (Price, Name, Description)
You have a fish in your hand. In this sentence, the fish a prefab. It has a state. (Size, Smell)

The SO is something that every fish share while the prefab is something that is unique for each fish.

#

In your case, that could be something like:

(SO)
Name: Golden Tire
Requires: Golden Engine

(Prefab)
Position: (0,0,0)
RemainingDurability: 0.25f

Is there a way I could just have a small window in the inspector for the scripableobject which renders the vehicle's mesh, even if just in wireframe, and any handles I want?

steady moat
#

That would be a lot of effort.

#

But not impossible.

#

The best would be to use the scene.

#

Or a temporary scene.

topaz ocean
#

like a prefab ._.

steady moat
#

No, that would need to be your whole car.

topaz ocean
#

why

#

I would never be instantiating it

steady moat
#

If you want to see how your piece looks in relation to your car you will need to construct your whole car.

#

Otherwise, how would you know what it looks like on your car if you have no car ?

topaz ocean
#

The radius of a wheel is not a property of the wheel, its a property of the chassis. So I only need to draw a circle to represent that value where it would be on the car.

steady moat
#

You could also have an editor on the car instead.

#

That would renderer every piece it can have.

topaz ocean
#

I already have that, the point would be for it to be visible as you update the SO

void basalt
#

@topaz oceanEveryone that makes vehicles just draws the wireframe using Gizmos in the scene view in the editor

#

Is there any reason this isn't good enough?

topaz ocean
#

because I will have to ping pong between editing the SO and previewing the change.

#

I dont see how thats much different from not seeing it at all and just waiting for it to generate

#

because technecally thats what I already have

image.png
steady moat
#

Is it not enough ?

void basalt
#

that's the standard. Everyone does it that way

topaz ocean
void basalt
#

But you can already preview the change

steady moat
#

You can also have multiple inspector if this is an issue.

topaz ocean
#

when I select the scripableobject the gizmos dont render

steady moat
#

And lock one of them.

steady moat
topaz ocean
#

that hijacks other gizmos

steady moat
#

You can also control the visibility of a gizmo.

#

You can also have an other inspector and lock it.

#

You could also have a custom editor on the car that can edit a scriptable object directly from it. (If they are proprities of the car)

topaz ocean
#

Im going to attempt to just add an inspector window which draws the mesh and params.

#

it will give my scriptableobjects some heft and make setup more intuitive

steady moat
#

Good luck.

Sorry to jump out of the topic, but I wonder, is there anyway to access the list of sprites, from a Texture set as multiple, without using Resource or Asset Database ? (In code I mean).
Right now, I don't see any other way of doing it, and I find it strange that's its not accessible !

Thank yooou !

potent sleet

#

The wording was a bit clumsy, I meant the property of the Texture2D which is "SpriteMode : Multiple".

Basically, doing so

Sprite[] sprites = Resources.LoadAll<Sprite>(texture.name);

Without using Resources.LoadAll which is not optimal at all.
