[static matrix]

wait I dont seem to have transformpoint

[leaden ice]

TransformPoint takes a local vector

[static matrix]

hmm

[leaden ice]

sorry Camera.main.transform.TransformPoint

[static matrix]

ok cool

hmmm I cant * to 2 vector3s

do I do + instead?

[leaden ice]

offset is a float

in my example

If you want a viewport point you can also do:

float distanceFromCamera = 5;
Vector3 viewportPos = new Vector3(0.5f, 0.5f, distance); // right in the middle of the viewport
Vector3 worldPos = Camera.main.ViewportToWorldPoint(viewportPos);

thank you, I might get it from here
Im reworking my entire inventory system because it was really really poorly done backend so I might have more questions

• worked

swell
ill model an arm later

[soft shard]

Are you making a Backrooms?

[static matrix]

i am making a backrooms

been going for a couple months now

have 2 levels done well with a third one on the way
although making a level doesnt take a month that also included setup and stuff

[soft shard]

Oh, neat, the beginning of a project building all the systems to automate development later, does take a lot of upfront time, good to hear your making progress

[static matrix]

thanks!
it was also just building the mechanics and such

many of which were very poorly done but functional

also like two weeks to realize how stupid I was on optimization

first commit was start of april

I made the very good and wise descision to not properly name things in blender and now have 30 materials called "Material.001"

[soft shard]

Functional is good, if it helps, you could look into inheritance, interfaces and "micro services" or "broadcasters/messages", they can essentially replace singletons and heavy dependencies, and both services and broadcasters dont require MonoBehaviour so they dont need to exist in any scene to work, interfaces could let you make shared functionality, like allowing anything with IDamagable to take damage or IInteractable to be picked up, etc - and inheritance would let you create base scripts, so you could have a Weapon : Mono and then a Axe : Weapon etc, might help organize your code, I found them a big help at least in my projects

[static matrix]

im using inheiritance
I use abstract a lot

I have that with Damagers, items, interactables

[soft shard]

Ah, abstract is good too, I use virtual more often personally, though either approach should help in less messy code, what do you think is "poor" about your approach?

[static matrix]

ehem

my code is pretty bad
its very messy

this is probably the worst offender tho, the script that stores all the player stats

(and manages)

[gray mural]

I think you should consider using headers and spaces

and serialize fields

[static matrix]

im getting better with Serialize
im using it more

[autumn scarab]

Hey guys posted previously on #💻┃code-beginner too so I'm sorry if this is not ok. I'm trying to use Quaternion.RotateTowards, but instead my object of pointing at the target, it I think tries to point to where the target is looking towards, resulting in my object literally pointing away from it.

thisT.rotation = Quaternion.RotateTowards(thisT.rotation, targetUnit.thisT.rotation, Time.deltaTime * trackingspeed);

[static matrix]

this script was written a while ago

[static matrix]

I mean, it does seem like you are telling it to point at the rotation

just tell it to point at targetUnit.transform.position

[autumn scarab]

Quaternion.RotateTowards doesn't allow using position unfortunately

It only allows quaternions

[pure cliff]

oh shoot wrong discord lol

[static matrix]

hmmm
theres a way to get the rotation towards something

you could also try Transform.LookAt()

[soft shard]

Some things that could help, if you want to "collapse" related data, you could put them in a serialized class

[System.Serializable]
public class WeaponData
{
//...
}

[System.Serializable]
public class WeaponDependencies
{
public SomeComponent example;
//...
}

public class Offender : Mono
{
[Header("Weapon Stuff")]
[SerializeField] WeaponData data;
[Header("References")]
[SerializeField] WeaponDependencies dependencies;
}

Or you could put it in a ScriptableObject instead, then you can create those SO files and even swap out data or have other systems share the same data if you wanted, I personally like combining the two approaches to also allow me to save that data to JSON if I wanted, but no reason the data couldnt just exist in the SO if you prefer

[CreateAssetMenu()]
public class WeaponSO : ScriptableObject
{
public WeaponData savableData;
}

[static matrix]

but that doesn't do it smoothly

[autumn scarab]

Yeah I need it to be smooth since it's a homing bullet. Thanks though!

[static matrix]

nono I gotchu

[autumn scarab]

It does rotate oh so very nicely away from it! :)

[static matrix]

 Vector3 targ = Player.transform.position;
          

            Vector3 objectPos = transform.position;
            targ.x = targ.x - objectPos.x;
            targ.y = targ.y - objectPos.y;
            targ.z = targ.z - objectPos.z;
transform.forward = Vector3.Slerp(transform.forward, targ, 0.1f);

here you are

(sorry about weird spacing, copying from visual studio sometimes does that)

[autumn scarab]

Thanks i'm going to try that.

[static matrix]

did it work out?

is it possible to have a mesh be always rendered on top of another one? I know in fps games they do a thing with a static image but that wont work here

[hard viper]

I have tilemaps with many different tiles with different types of logic. My issue is if I use a composite collider, I need to figure out the ID of the tile I hit. If I could find out what cell on the tilemap I made contact with, I could easily take it from there. Any suggestions?

[static matrix]

do particles stay if the spawning object is destroyed?

[shadow grove]

how do you scale ui equally across all resolutions?

[rain minnow]

Yes . . .

[shadow grove]

should i scale with screen size?

and for anchors do i set them all to zero

[somber nacelle]

Check the docs pinned in #📲┃ui-ux for info about scaling and anchoring your UI

[shadow grove]

will using scale with screen size give me problems though

[swift falcon]

can someone heelp with my error InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings.

[shadow grove]

is it not letting you run the game? I have gotten that error before

[somber nacelle]

Did you read what it is telling you?

[shadow grove]

I think if you go to your project settings(Edit/ProjectSetting/), check Input system package and input manage

you might find something there

[lean sail]

This error is quite specific, look at the file and line its telling you to look at

[shadow grove]

I dont even think it is a problem that stops anything as i have gotten it befor

[swift falcon]

uh

ok

[oak steppe]

Hey can anyone explain to me please how I can get this script running?

https://github.com/Straafe/unity-editor-tools/blob/master/ReverseAnimationContext.cs

[swift falcon]

wheres input manage

[oak steppe]

It adds a function to the unity editor which I havent done yet. it lets you reverse animations

[lean sail]

Well it is an error.

[swift falcon]

..

where

[shadow grove]

input manager

[swift falcon]

o

[shadow grove]

go to project settings

[swift falcon]

ill take a pick of my error

go to player settings, in the search bar type active input handling

set it to both

or project settings

[swift falcon]

what search bar

call me

[lean sail]

Just use the new input system if you're gonna use the new input system...

[swift falcon]

how

[trim ferry]

guys im making a script for my enemy to die, but i want the shatters Destroy after 3 seconds, but my original gameobject not shattered is already destroyed and replaced with the shattered one without any script, and i have an IEnumerator.. How do i make my shatters destroy after my gameobject with the script has been destroyed?? Here's the script: https://hatebin.com/plnsckrqfq

[swift falcon]

thank you logan👍

[shadow grove]

did it work?

[lean sail]

You really dont need to do that, you've been sent on a goose chase. You've enabled the new input system and arent using it, that is quite literally the entire error.

[swift falcon]

yea

[shadow grove]

what would be ur souluion bawsi

just curious

[flint dawn]

hello guys, I can't move my character, it's moving by itself right to left until it stops
is it because of this code?

[lean sail]

@shadow grove

[shadow grove]

yeah i guess

but he is probably following tutotrials that use a mixture of both the old input system and the new one

[lean sail]

So just use one

You dont need to follow a tutorial letter by letter

[shadow grove]

maybe because if you press it you are not checking to see if the key has been lifted, so nothing is stopping the force from continiung

[lean sail]

🤷‍♂️ no point adding the new input system if you are gonna checkmark to use both, then only read input from the legacy system

[shadow grove]

so check to see if one key is lifted then clear the force

[somber nacelle]

1. don't addforce in update except for one-off forces using ForceMode.Impulse, do physics in FixedUpdate
2. don't multiply your forces by deltaTime
3. reduce the amount of force you are applying
4. provide more actual information about the issue you are experience, see #854851968446365696 for what to include when asking for help

[flint dawn]

thank you

I will try to record the issue

[trim ferry]

Guys, is there anyway to start a coroutine after the gameobject is destroyed?

[somber nacelle]

not on that gameobject. you can start a coroutine on some other game object though, just fire an event in OnDestroy or whatever to notify subscribers that the object has been destroyed

[trim ferry]

do i need another script for tht?

[wary coyote]

data writing question - I have a script that encodes barycentric coordinate data into mesh vertex colors.
The data only needs to be encoded one single time. I am not versed in editor scripting however, is there some way I can write that data into the meshes, outside of the scene outside of at 'Start'?
because I dont want to be setting meshes to writable at runtime and calculating this at Start if it can all be pre-packaged

currently the method I use to write the data only works in editor and fails in build because its happening OnValidate, but the mesh isnt permanently gaining that data, it's local to the editor scene

[somber nacelle]

well you do need to write code to do it. whether you put that code into an existing scripts or some other scripts is up to you

[trim ferry]

what does this mean

is it dangerous or no

[somber nacelle]

seems like you're destroying a prefab rather than the instance of an object

[trim ferry]

bruh

[vestal summit]

Why is every script that contains an Awake function disables them selfs when the object instantiates? I didn't have this bug this morning but now all of the sudden I do. Anyway to fix this? Could this be the cause of netcode networking?

[trim ferry]

(other script)

[somber nacelle]

i don't know what you think this is supposed to prove considering it does not show that you are or are not passing a prefab

[leaden ice]

This happens if your code throws an exception in Awake

[somber nacelle]

if these are network objects you probably need to make sure they are spawned on the network and not just instantiated

[trim ferry]

that is a variable that contains the shattered version

[somber nacelle]

is the "shattered version" a prefab?

[trim ferry]

yeah

[somber nacelle]

so you're passing a prefab to Destroy instead of the instantiated instance

which is exactly what i told you already

[vestal summit]

as I said everything was ok before, I used the same things. But after some time I did some scripting on other scripts and it caused that issue to disable every single script that contains Awake. Plus most of those script doesn't even have a NetworkBehaviour nor networkObject

[trim ferry]

but i destroy the original not shattered version and instantiate the shattered version from the prefab folder man

[leaden ice]

not what your code says

either way you shouldn't be destroying "the original". You should only be destroying scene instances

[trim ferry]

not the original prefab in destroying, the instanced one

[vestal summit]

Fixing all bugs would fix it you say? Most of the bugs that I have makes no sense but I'll see what I can do.

[leaden ice]

I didn't say fixing all bugs would fix it

I said a very specific thing

if your Awake function throws an exception it will disable the script

[vestal summit]

the strange thing is that I don't even have any bugs I just realised. It's marking random lines and saying that that's the bug even thought it isn't cause it worked 2 hours ago and I didn't change anything in there

it's doing that on 10 different scripts

[somber nacelle]

but you literally just said that the destroyedVersion variable is a reference to a prefab

[vestal summit]

plus I'm not even sure if it's cause of Awake functions.

[leaden ice]

I don't even have any bugs I just realised
If your code is not working as you expect, that is the defnition of a bug. You are confusing errors with bugs.
It's marking random lines and saying that that's the bug even thought it isn't
I believe the compiler over you, sorry.

If you want further help, share your code and the error messages you're seeing

[trim ferry]

forget it

[vestal summit]

I thought it's cause of that cause only the scripts that contains an Awake function got disabled. But the null exception bug marks that it's somewhere else

[leaden ice]

Any time an exception is thrown from Awake, it will disable the script

that's it

[hasty haven]

Hey again, i'm working on making my voxel engine allow beveled edges.
I believe there will be 2^14 possible block combinations, so a dictionary of size 16384, that sound reasonable? LOL

[somber nacelle]

you need to pass the instantied "shattered version" to Destroy instead of the prefab. but if you are just going to give up because you don't like what i'm telling you, then good luck 🤷‍♂️ won't last long in the dev industry if you give up at the slightest inconvenience

[vestal summit]

quick example of one script that is throwing this error. And the line

[trim ferry]

its not because i dont like what you are saying, its because i am not understanding and i dont have much time to explain

[vestal summit]

not going to show more code cause it wouldn't help either way most likely

[dusk apex]

Key binds is null

[somber nacelle]

the destroyedVersion variable references a prefab. you instantiate that prefab somewhere. but instead of storing the instantiated object and passing that to Destroy, you pass destroyedVersion which as we have established is a prefab. hence the error about destroying assets because prefabs are assets

[dusk apex]

An NRE occurs when you attempt to access a member (field, function, property etc) of a variable while the variable is null.

[leaden ice]

looks like keyBinds is null. The error makes perfect sense.

[trim ferry]

this should work right?

[dusk apex]

No certainty

[vestal summit]

k that is the reason some how. Can you explain how is this not getting the keybinds script? :P

[leaden ice]

because there's no _Keybinds component attached to this GameObject (the one this script is on)

[somber nacelle]

i mean, i guess. but you should just store the reference when you instantiate it. you can even just call Destroy on literally the line right after instantiation because you can pass the delay to Destroy instead of using a coroutine

and for future reference, if you don't understand something then fucking ask. i have no way of knowing what you do or do not understand so you have to make it clear so it can be explained

[dusk apex]

It did not exist when you tried to find it - would be a possibility.

[vestal summit]

there is

[leaden ice]

this screenshot shows nothing

it shows that script is on some object

[dusk apex]

Stop it with the miniscule images please

[trim ferry]

wdym delay of destroy

[leaden ice]

this code also doesn't actually show where this line is

or prove that it's even running

Not enough info as is

We're just certain that it's null when it's executed - assuming that's the correct script/location

[trim ferry]

no way they had that and i didnt know

bruh cmon 😭

[somber nacelle]

pay attention to the docs and what intellisense shows, you should have seen the tooltip with the parameters in your IDE

[trim ferry]

i dont read that much docs

[leaden ice]

You only have ONE GpulseTurret in the scene, guaranteed?

[leaden ice]

fix that

you CAN'T make games or write any code without reading docs

constantly

[vestal summit]

ok wait give me a sec I'll figure out something. The issue is that it's not getting the components at all so I'll just add em manually. Still don't understand why is it like that

[trim ferry]

idk man its hard to interpret

[leaden ice]

It will be for standard/typical reasons. There's no mystery:

• The component isn't on the same object
• The code that sets it isn't running

[dusk apex]

Tbf, the simpler your game is the less reading you'll need but still.

[trim ferry]

im kind of lazy

[vestal summit]

the component is on the same object. The reason why is it not getting it is cause the component that should be getting it is getting disabled for who knows why

[trim ferry]

man why tf does it keep counting as a prefab

[vestal summit]

so if it's disabled it's not running the awake at all and not getting the component

I might be able to fix the issue by simply assigning the components instead

[leaden ice]

it's getting disabled because of an exception being thrown in Awake

You need to look at your console

find the exception

and fix it

there's no magic.

[somber nacelle]

show the code you have to destroy the object now

[trim ferry]

https://hatebin.com/oyrpmchdjl

[leaden ice]

you're literally just passing the prefab in to Destroy

not sure what you expect

it does exactly what you tell it to do

[somber nacelle]

assign the returned object from Instantiate to a local variable and pass that in, not the prefab

[trim ferry]

then how am i gonna spawn them by script in my terrain?

[somber nacelle]

huh?

[trim ferry]

these enemies will spawn randomly in my terrain

[leaden ice]

so?

[somber nacelle]

i'm guessing you haven't bothered looking at the docs or tooltip for the Instantiate method

it returns the instantiated object

[trim ferry]

oh wait

nvm

forget the spawn things i said

[trim ferry]

one minute, i will have to translate this

ok, im gonna try

nop

[somber nacelle]

show what you tried

[trim ferry]

i didnt change the script, i just spawned a shattered one in the world and used it in the variable

wait

one sec

[ionic grove]

How do you guys handle child and parent colliders that are triggers? I can't seem to separate them. In the screenshot, both of these have triggers on them and both trigger the OnTriggerStay function of the parent

[leaden ice]

You would have to put a kinematic rigidbody on the child if you want to separate the messages

[steady moat]

Side by Side or multiple kinematic rigidbody

[leaden ice]

all colliders under a Rigidbody are part of that body. So the Rigidbodies are the separation points

[ionic grove]

Ohhhh, ok I'll try putting a RB on the child GO. The parent is currently the only one with one on it

[trim ferry]

i didnt change the script, i just spawned a shattered one in the world and used it in the variable

and it doesnt work

[ionic grove]

That worked! Thanks a ton guys 🙂

[somber nacelle]

well obviously. that's not what i told you to do

this is literally as simple as doing var obj = Instantiate(destroyedVersion); Destroy(obj, whatevertime);

[leaden ice]

Why not just do what has been recommended to you?

Because what you just said makes no sense

[trim ferry]

idk wtf i have to do, i dont speak english man

[somber nacelle]

read the messages

[trim ferry]

im just translating things, and most of them doesnt make sense for me

[flint dawn]

that's what happens
the console doesn't says about any error, my character is a game object with both box collider 2d and rigidbody 2d, only with the script for the movement

[somber nacelle]

i gave you the answer #archived-code-general message

[dusk apex]

Doesn't look like he's got a box collider

[trim ferry]

like this?

[somber nacelle]

bro what

why are you instantiating it twice

[trim ferry]

wait

because its a var

a variable

[ashen yoke]

please take some time to understand what you wrote yourself

simulate that code in your head, taking into account what you learned about method returns

[trim ferry]

like this then

i think it is

[somber nacelle]

yes

[flint dawn]

it does

(sorry for the bad image quality)

[trim ferry]

can i put the destroyedVersion variable object from the prefab or no?

[somber nacelle]

yes, the destroyedVersion variable should be a reference to the prefab

[trim ferry]

ok

[dusk apex]

The video illustrates that it has somehow got colliders for arms and feet.

[trim ferry]

IT WORKED FINALLY

thank you

and im sorry too

[flint dawn]

the character is made of body parts (body, two eyes, two feet and two hands), all of them inside the GameObject
should I put a box collider only on the feet?

[dusk apex]

If they're all solid, they'll force one another to be displaced if intersecting. You can use the physics layer matrix to have certain colliders ignore each other.
https://docs.unity3d.com/Manual/LayerBasedCollision.html

[flint dawn]

I'll read it, thank you

[stone rock]

Hello, i am checking how the directions work on the built in wheel colliders and would like to replicate the same results with a raycast

anyone know the correct math functions to get this result?

it seems to stay flat to the surface but uses the steeringangle sort of to like follow the wheel

[stone rock]

I think i found it these 2 lines seem to reproduce the results exactly like the wheel colliders

forward = (-Vector3.Cross(rayHit.normal, wheel.transform.right)).normalized;
right = Vector3.Cross(rayHit.normal, wheel.transform.forward).normalized;

just need to make the transform.right and forward be adjusted with the steering angle

[topaz ocean]

I have a script that requires a couple of gameobjects with their own components, and I find myself making a lot of if(component!=null) statements for these references. Im setting these systems up in prefabs but dread the possibility of somehow running into a null pointer exception. Is there some way to make it impossible for instances of these prefabs to have their references emptied or something?

Ive considered making the references properties where each time I reference them I do a "GetComponentInChildren" but im not sure if this is even more wasteful than doing a null check in almost every function.

[lean sail]

You can just check if its null once and throw an error if it's supposed to be there. If the script is on the same object, then u can use [RequireComponent()], I forget the exact syntax

[somber nacelle]

make the variables private so other objects cannot access them. use the RequireComponent attribute to ensure your components are on objects that have the required components. serialize the references to the other components so you don't need to use GetComponent or whatever in Awake/Start. use TryGetComponent in methods where you are calling GetComponent and doing null checks since it combines both into one line

[topaz ocean]

What im doing right now is making a script for each child object which holds a "RequireComponent" and Property accessor to the component, then I slot references to those in the parent script.

I guess my explanation boils down to 2 questions.

1. Can I trust prefabs to not randomly lose data
2. Is it really okay to have a script that will trigger errors if one of its references is null.

[lean sail]

The error would be so you know that the reference has not been assigned. It shouldnt randomly lose its data, especially if you're just referencing stuff in the same prefab

[prime mica]

does anyone know why my projectile randomly just ignores all collisions/triggers? if I get a certain distance away from the firing object, it collides but too close and it just goes through it.

[somber nacelle]

how are you moving it?

[prime mica]

adding relative impulse to a rigidbody attached to the projectile

[somber nacelle]

make sure that the collision detection on the rigidbody is set to continuous. it's possible that it's moving too quickly for it to properly detect collisions

[upbeat hare]

you have to freeze the rotation of player's Movement

[upbeat hare]

hold on im gonna open unity to show you

here

[zealous hemlock]

Does anyone know where I can get code for a mobile game controller mechanics (just need for left and right movement - x axis)

[vestal anchor]

anyone know a good video? or have a good procedule map generation?

[flint dawn]

do you mean the "z"?
I did this and my character started trembling

like this

[quick elbow]

Is the built-in untiy character controller any good for controlling movement of vehicles such as a plane or helicopter? If not, what would you recommend? Should I write my own character controller from scratch?

Additionally, I was looking at the free Kinematic Character Controller on the Unity Asset Store which was built from scratch (specifically for character movement). The script is almost 2k lines long. Obviously it adds a lot of features that the built-in CharacterController doesn't offer out of the box. However, I noticed the asset doesn't even leverage the built-in controller and build on top of it. How come?

[cosmic rain]

Depends how realistic you need it to be. If not realistic at all, then it should be good enough. If somewhat resembling real plane or helicopter movement, then you'd need to implement your own or look for an asset.

[cosmic rain]

Simply because the built-in character controller is not very useful for anything slightly more complex than a very basic arcade game.

[ashen yoke]

how come? the asset is conceptually different to every other approach before it

those 2k lines achieve very barebones functionality, compared to other assets, that have ladders, wall climbing etc

however kcc has almost zero edge cases where it fails at whats advertised

[trim ferry]

what is hapenning here i just opened unity

[ashen yoke]

i assume its not zero, but i havent encountered a single case where it would get stuck or broke on any geometry

and the way its designed gives you full access to all transient data, and has several extension points during internal phases where you can extend to do whatever you want

as for planes nothing built in or kcc or cc will work

either DIY with forces, vector fields for surfaces or some asset that does the same

[leaden ice]

You see to have imported the "Standard Assets" package which is very outdated

[ashen yoke]

theres another one, starter assets or something

also by unity

[trim ferry]

yes i do but 2 minutes ago it was working

this is hapenning

[leaden ice]

you don't have a class called Waypoint

[trim ferry]

but how does it suddenly makes this error

[leaden ice]

how should I know

you don't have a class called Waypoint

so it doesn't work

prove me wrong

maybe you deleted the Waypoint class?

Or maybe Waypoint is in another Assembly?

[trim ferry]

so what do i do? i have to create a script or smt?

[leaden ice]

there is literally no way for me to answer that

are you following a tutorial or something?

Do what the tutorial says

[trim ferry]

nah man

[hidden compass]

u either have to re-create it orr.. u have to delete all teh scripts that try to reference it

[trim ferry]

last time i closed unity was when i finished a script

[leaden ice]

you couldn't have gotten to this point without knowing what to do unless you nabbed this code from a tutorial or something

[trim ferry]

and i tested it

[leaden ice]

or from a library

[trim ferry]

it was perfectly fine

[leaden ice]

in which case - install the library properly

[trim ferry]

well, i tried to import an asset

it said that it would mess with my scripts and blabla

but i clicked "No, Thanks"

[leaden ice]

what do you mean by "it sauid would mess with my scripts

[trim ferry]

let me screenshot it

i have a feeling

man

i think

waypoint circuit and waypoint progress tracker is from the asset

idk

how is this been created in 2016

i created this project 1 year ago

[leaden ice]

where is Waypoint defined?

[spring creek]

The RealisticDrone creator made it in 2016 is my guess

[hidden compass]

the waypoint error stuff is coming from Unity's Standard Assets

which i guess was used by the Realistic Drone asset

i downloaded the old assets

i have both waypoint scripts he has
altho straight from unity that script inherits from MonoBehaviour

not Waypoint

broken asset, there is no Waypoint

[somber nacelle]

why are you even using the Standard Assets anyway? they've been deprecated and replaced with the Starter Assets

oh i see, it was because of some other asset

[hidden compass]

#archived-code-general message

the Realistic Drone asset he imported uses it's Waypoint system.. and changed it to inherit a script its missing lol

ya.. and then the didnt even include the Waypoint script

so. solutions are.. delete the asset, or figure out what Waypoint was meant to do and rewrite it, or better yet just delete that out of the asset and re-do a waypoint system of ur own when it comes time

[silk cairn]

if I make a bunch of trees with terrain painting, is there a way I can make them all interactable? I want to be able to chop them down

or would I have to manually place all the trees lmao

[hidden compass]

https://forum.unity.com/threads/how-to-chop-tree-down-in-unity-terrain.202991/

may have some useful information in this thread

the one about terrainData a few posts down specifically

[silk cairn]

sounds complicated

[rose dragon]

Ive normalized each of my vectors but still am having an issue where the player moves faster when going diagnol. Anyone know what else I can do?

have we ever found out why everyone does this? :

private int placeHolder;

I know it's preference but where did it start?

[quartz folio]

Unity used some conventions from C++, some people use some mismatched conventions that are considered legacy, and others use the Microsoft .NET/C# conventions (+Unity uses them for new packages)

[swift falcon]

Oh right, wasn't unity built in C++ aswell??

[quartz folio]

Yes

[swift falcon]

Alright thanks for answering my 3AM questions

[pure cliff]

It's pretty normal to do private fields in camelCase, or _camelCase, for C# in general

[balmy gull]

Pythagorean theorem

[somber nacelle]

normalizing a vector solves the issue you are alluding to. when you normalize a vector it's length becomes one, so a vector2 (1,1) becomes )0.7071, 0.7071) when normalized

Hi! I have a problem with limiting drag distance in my darg and snap script. The script is not limiting the drag distance but placeing the object to the player with the distance of maxDistance also it's made to work for multiplayer. here is the script:https://hastebin.com/share/tefulilutu.csharp

Can anyone help i have been stuck on this problem for over 2 weeks

[gentle relic]

Hello Friends, this is Otz, I am having some programming difficulties, it's terminal, and I would like some assistance. I'm attempting to rotate some platforms, but I'm having a few different issues. This problem has been very complicated and unnecessarily difficult for me to solve. Here are all the details, code examples, and demonstrations, as well as everything I've tried to come to a solutiojn -> https://stackoverflow.com/questions/76735104/unity-how-can-i-rotate-multiple-objects-in-a-constant-matter-without-using-par

[gentle relic]

Hello! I appreciate the quick response, but I actually did try that, as mentioned in the post. The issue is that the panels rotate around a parent object, which is also rotating, meaning the the objects move around in a circular pattern. This causes an issue where the location of the panels during their rotation is not consistent, demonstrated in this video, linked on the stack overflow post -> https://youtu.be/aa82rNaTyzs

Could you elaborate on what you mean exactly?

How could I implement it so it's done correctly?

By this comment did you mean I was brute-forcing it by rotating panels individually or by rotating the panels on individual parents?

I moved on to a different solution because people suggested I should. People suggested a fix, I implemented it, and the fix didn't work. I've really only tried two approaches: rotating on a parent and rotating the individual panels. If I knew why it didn't work I wouldn't have asked for help 😅

[lucid matrix]

Hey, can you tell my why is value between 0-1 on animationcurve , can I changde it to be like 3000 on X axis ans 700 on y?

[gentle relic]

The value on an animation curve is 0 - 1 because it means from 0% to 100%, so I don't think it can go above that amount

Though I've only used them a handfull of times so not 100% on that

[lucid matrix]

in window? I could not, can you suggest a way?

here?

I remember I could change this here but I am on 2022 lts, is there anything changed?

:d

I used this but

it still does not go above 0-1

I can drag it but, how much I have to zoom out

to get like 2000

from 1

[lucid matrix]

I remember somehow it can be changed

How do tou do? Using new KeyFrame()?

Hm how

No, do not open it

I click right key

an this happens

when clicking

it adds

Not working

it still shows Add Key

I asked gpt to create this

but

when I open I cannot modify because it is zoomed in

Ahhstrange

👀

Okay, thank you, maybe it is a bug, or feature of new 2022 lts

idk

[gentle relic]

What was your solution that you had in mind for this?

But... the point of the post is because I wasn't able to figure out what went wrong?

What do you believe I am doing wrong?

What information about the bug do you believe you're missing that would be helpful to find a solution?

[pliant anvil]

Hey guys, i've checked out 5 tutorials for the VFX Graph, but no matter what i try, when i create a VFX Graph etc i just see a teacup, no particles or effects. What am i doing wrong?

[simple egret]

Ask in #✨┃vfx-and-particles

[gentle relic]

I've spent a lot of time debugging before posting. What information, when provided, would be helpful for you, because I feel like I've done an adequate job describing and demonstrating the problem I've had with both approaches

I need to know what you need, so I can help you help me

Is there any notable information you're trying to find? It sounds like you're referencing a specific setting or other. I can simply prvide the information you're looking for, be it the position, rotation, or otherwise

The only things I would've done are:
1 - Import the models and put into the scene as game objects
2 - Position a 6 of the models
3 - Set the rotation of all 6 of the models
4 - Create parents and set them as children

All the information is contained in the Transform component, which and the hierarchy is visiible in the images. The transform component only has scale, rotation, and position, so It's not like there's any complicated steps I could've done or settings I could've messed with. All the information is there, any any information that is not I can provide, so I'm not exactly sure what you're looking for and it doesn't sound like you know what you're looking for either

[gentle relic]

Step 5 would be to run the code that's shown on the post

Could you let me know what information you're trying to find?

Again, there are very little settings in the transform and no other scripts attached to the platforms

go ahead

Could you let me know what you mean by the pivot is correct?

The only way to change the pivot in a 3D scene is with a parent, no?

Referring to the model or the game object?

That's why I was confused

you're suggesting the pivot of the model is off?

Good night

How do I get rid of DontDestroyOnLoad and how did it get there

[rigid island]

huh remove the line

[ocean osprey]

what line

[rigid island]

DontDestroyOnLoad

[ocean osprey]

theres no line for that

i dont rember creating it

[rigid island]

then there is no DontDestroyOnLoad object

[ocean osprey]

it only shows up when i press play

[rigid island]

but is it empty?

[ocean osprey]

no

[rigid island]

so whatever is in it has DontDestroyOnLoad on it

[simple egret]

That's a scene, not an object. It's there to store debug stuff sometimes, I've seen

[ocean osprey]

how do i get rid of it

[simple egret]

You don't

[ocean osprey]

i just want it gone

what

[rigid island]

it's part of unity

[ocean osprey]

how did it get there

[rigid island]

for DDOL objects

[simple egret]

It's required for the said debug stuff to work

[ocean osprey]

how do i stop it from loading objects into the scene then

[simple egret]

You don't, it's required for the said debug stuff to work

[rigid island]

it's not loading anything into the scene

it's its own contained scene

[ocean osprey]

its cloning stuff

[simple egret]

How about you expand it to see what's in it?

[ocean osprey]

[simple egret]

There we go

[ocean osprey]

whats that about

The debug stuff I've been talking about, like 4 times

[rigid island]

its the entry point for debug

[ocean osprey]

ill look for something else

[simple egret]

You cannot get rid of it. It's required by some Unity package or object

[ocean osprey]

like what

[rigid island]

it's normal in SRP

[rigid island]

#archived-code-general message

[simple egret]

Yeah that's the render pipeline thing

[ocean osprey]

i mean what kind of object

[rigid island]

inside Core RP Library i think

[simple egret]

Why care about it? It's required to work, so you don't touch it

[rigid island]

you shouldn't worry or touch it

[ocean osprey]

ok then

[gentle relic]

You were pretty intentionally unhelpful and rude most of the time but I think I may have identified the problem

[rigid island]

it won't be in your build so who cares

[gentle relic]

Anyways, peace

[ocean osprey]

One more thing, how do I detect if two objects are touching from a script thats not attached to either of the two objects

[prime sinew]

Probably more trouble than worth, but get the reference of both the objects then do overlapsphere or distance check with the widths of the objects

[ocean osprey]

ok

[simple egret]

Another option would be to have an event that gets invoked when the objects collide. The third object that needs to know can subscribe to it

[echo zinc]

Can anyone help i have been stuck on this problem for over 2 weeks

please

[prime sinew]

No one can help if they don't know what the problem is

When I stop the playmode I get this error:
Cannot set the parent of the GameObject 'Player(Clone)' while activating or deactivating the parent GameObject 'Parenting Obj'.

of course the error doesnt happen when the game object isnt in the trigger... but it still annoys me if i stop playmode while the player object is on the trigger... can someone help how I remove the error? I tried to use Try/catch and it didnt work

You could try setting the parent in a Couroutine with a slight delay. It would desynchronize it though.

[thin hollow]

Can somebody point me to any good article about the practical serialization of parameters for saving, instead of the ones that merely state that serialization is possible and you should use it?
I'm making a save system for my game to do persistent changes in the levels, and so far I managed to code a system to store most of the basic variables by converting them to strings in kind of this hierarchy:

dictionary of data from all the levels; by level's name
    dictionary of all objects on a level; by object's unique GUID
        dictionary of struct that contains variable's name, value, and type; by variable's name

converting seems simple - for most variables just .ToString() is enough.
However I'm not sure how to proceed for stuff like dictionaries, structs and most importantly - referential links (for example my camera prefab can be set to look at a specific gameObject instead of at the player - how do I store and restore this change?)
From what I was able to gather serialization should do exactly this - convert a variable to a string entry and be able to convert it back from it to a variable.
However, most articles are either talk about this in a very abstract way or basically say only "just put [SerializeField] before your variable declaration, lol"

[leaden ice]

serialization is just a basic concept that means "converting a complex graph of data in memory into a serial form so it can be written to a file or sent over the network"

In practical reality there are many tools for serializing things into many different formats, and each of these tools has is own set of very specific rules about how it works

But from your description here I think before you even get to that point you really need to step back and have a think about what information you actually need to serialize

converting seems simple - for most variables just .ToString() is enough.
Also this seems like you are trying to build your own serialization tool from scratch, which I wouldn't really recommend

[cold egret]

- Is there any real reason why should i avoid binary formatting? Other than "imagine if hackers publish your game with modified binary" or "microsoft says so"? Like, real reasons

[thin hollow]

Well, like I said, all articles are saying just that serialization is a thing that exists and here's a couple of interfaces it uses, but not how to actually operate it for your own goals.

[crude mortar]

There is JSON serialization, XML serialization, binary serialization, and many other random serialization formats. There are many libraries for C# serialization on github that have in-depth documentation on how to use them. All you need to do, most of the time, is somehow tag certain objects and variables as being serializable (usually with attributes) to get them serialized. To "actually operate it for your own goals" depends on what your goals are. All it does is turn your variables into bytes or text that can be written to a file, and then read back later. Unfortunately you cannot just serialize your whole Unity scene and boot it back up. What you have to do is a bit trickier.

If you are serializing your camera that is set to look at another object instead of the player, that object would likely need some ID that gets serialized along with any other relevant information such as its position, rotation, health, whatever. Then, you need to write code more like "Look at thing with this id", in theory at least. Loading the game would mean deserializing the save file, and recreating the state of the scene via your IDs and whatever other information you might need to reconstruct it. Perhaps, first, you would serialize the type of prefab the object is, then the custom instance id of that object, and then the other information (in that order). Reading it back, you would need to use the prefab id to map to some prefab in your game, then you would instantiate it. You would assign it the instance id next, then you would assign all the other relevant data. Your camera would undergo a similar process. The camera code would then need to try and use the instance ID to get a reference to the object's transform at "runtime", post-serialization.

Experimenting with what you can and cannot easily do with serialization will define how you structure your game state, and it is not something that could be fully covered by some tutorial—assuming your game is anywhere near complex.

[deep cobalt]

Hello, I am a little confused about prefabs, basically I imported models, gave them components/values and then turned each into a prefab.
Then once a prefab is instanced in the scene, it's made up of two gameobjects, the root of the instanced prefab (that only has a Transform component) and then there's the child object that is the actual model and components.

Isn't it kind of a waste to have two gameobjects?
I am making a level editor, so I can spawn and place props ingame and those props are selected by raycasting and the collider is on the child object (of the instanced prefab).
So I am left wondering if I should update the transform of the child object, or the root/parent (that is, the instance of the prefab).

[thin hollow]

I think it is a good idea to always work on the parent object whenever possible.

[crude mortar]

When I can, I like to put my collider and scripts onto the parent object, and have the graphics be the child. Sometimes this is doesn't work well, like if you have a skinned mesh and need to have colliders that move with the bones, but most of the time it does work. But if every single prefab has a parent for no reason, then I would say it's unnecessary. You would have to actually be using the parent for it to be relevant.

[leaden ice]

Because serialization is just a concept not some specific library or whatever

[thin hollow]

If you are serializing your camera that is set to look at another object instead of the player, that object would likely need some ID that gets serialized along with any other relevant information such as its position, rotation, health, whatever. Then, you need to write code more like "Look at thing with this id", in theory at least.
Hm, so basically "references can't be serialized, you need to do hacky ways around that to retain them"? This sort of sucks.

[crude mortar]

Yes, it does suck.

This is why data driven approaches to game development can be nice. This kind of ID mapping is usually built-in (Entity Component System for example), or you don't need many references in the first place, but you will always have to deal with Unity gameobjects being instantiated / destroyed on save / load.

[thin hollow]

then again, luckily I don't think I have many that are worth preserving yet, I think it would be only in the camera object and the NPC's AI system.

[deep cobalt]

Thanks, I'lll use the parent, though just wondering, is there a way for the prefab to be a single game object?

[small ember]

If I'm making a sports simulation game, what's the best way to preserve data? a relational database JSON? Something else?

[crude mortar]

What do you mean? You mean is it possible for models to also be a prefab?

I am actually not sure, I will have to check if there is a setting.

[thin hollow]

I don't think that my prefabs have any additional parent objects, maybe you are creating them incorrectly?

[crude mortar]

Well if you just drag a model into the scene, then drag it back into the assets to create a prefab, it will actually add an empty gameobject to the root.

But perhaps that is because it has multiple relevant children? Or perhaps it's dependent on the hierarchy of the model?

[thin hollow]

Strange... Just tested it, it doesn't that for me:

[crude mortar]

I just tested, it is because of armatures. The basic cube exports like your lantern there

If your model has an armature, it makes sense that it would create an empty gameobject to represent it, as moving the armature would want to move all child meshes.

[thin hollow]

How to spot a Blender user =D

[crude mortar]

There is likely an export setting to remove the root armature node from getting exported into the fbx, but I am not sure if you would want to do that most of the time.

Either way, it's a model issue, not a game engine issue

[small ember]

Should I be using scriptable objects to create classes? IE: Using a scriptable items object just as like the constructor for my actual items so I'm not spawning in a bunch of scriptable objects?

[latent latch]

use scriptable as immutable (readonly) data

[crude mortar]

There are assets on the asset store for saving / loading GameObjects and Components—asssuming you needed it and didn't want to make your own system for it. They usually cost a decent amount of money though. https://assetstore.unity.com/packages/tools/utilities/easy-save-the-complete-save-data-serializer-system-768 This is a very popular one for example.

[small ember]

So yes then. If I wanted items to be affectable I could create a potion scriptable object that at runtime created the potion class. Then if I wanted to affect it, I'd affect the potions class, not the scriptable object

I got that right?

[crude mortar]

Yes

[latent latch]

Right, scriptable serves as default values. If they weren't available, you'd use plain text or json otherwise

[small ember]

Is there any way to link them easily with classes using scripting? IE: Right now if I had a 'person' class with attributes such as hp, def, magic, I'd duplicate those in the scriptable object for the constructor. Any way to make it so if I added a 'luck' attribute to the person class later on, it'd automatically be created in my scriptable object constructor?

[latent latch]

You can write to them, or use them has a single static instance (much like a singleton pattern), but it's probably better to understand why'd you do that over doing it the general way with monos and c# classes

[small ember]

Sorry, I don't understand what you mean

I'm making a 'sports' simulator and the usecase here is so I can quickly create people on the backend. I am going to start with limited statistics and add more as I move forward

[latent latch]

I'm just advising writing to scriptable objects as an alternative, because you can overwrite data if you're not careful

which can affect other object instances uses that same data to read from

[small ember]

Ah, I see

[latent latch]

In this case, you'd have a scriptable object profile for each person class that serves as the default values; person object* one always starts with 100 hp

and if multiple people play as that person object, they'd all also start with that 100hp default value

[crude mortar]

Make a struct for the data, then have an instance of the struct in both your Person class and the scriptable object

[small ember]

Ooh that might be it

[latent latch]

Remember, you can't use the constructor when initing monos, but you can make your own init methods to feed it the data

[small ember]

Yeah that's what I'd do!

In the class make a method that just grabs all that data

[small ember]

So would my struct be like 'stat block' or something, in this case?

[crude mortar]

you would just do something like this:

[Serializable]
public struct PersonData {
  public int health;
  public int maxHealth;
  public int defense;
}

public sealed class PersonConfig : ScriptableObject {
  [field: SerializeField] public PersonData Data { get; private set; }
}

public sealed class Person : MonoBehaviour {
  private PersonData m_data;

  public void ApplyConfig(in PersonConfig config) => m_data = config.Data; // do other stuff if necessary
}

If you need this to be shared with other things, you would make more generalized names, but this is the idea.

[crude mortar]

sure

[small ember]

once those stats are in 'preson' are they easily changeable?

[crude mortar]

yes you just change the copy that the Person has

[small ember]

Can you go in and change individual elements

[crude mortar]

because it is struct (value type) it will not change the scriptable object

yes you can

[small ember]

like PersonData.health = 5

[crude mortar]

in my example you would do m_data.health = 5; yes

In the Person class

[solar current]

to disable object use SetActive(true) or (false) SetActive(true) or (false) SetActive(true) or (false) SetActive(true) or (false) SetActive(true) or (false) SetActive(true) or (false)

[soft shard]

Im getting an issue I dont understand, using a Physics visualizer for the editor, some dll code is spamming the console with "Look rotation viewing vector is zero" whenever im running by my AI that force them to flip directions to look at me, im not sure what "viewing vector" is actually referring to in the code im using, since not a single axis is 0, but it seems to care about the source.z for some reason (which is also not 0)

bool IsInLOS()
        {
            var source = head.position;
            var target = rayHit.collider.transform.position;

            Vertx.Debugging.DrawPhysics.Linecast(source, target, out hit); //produces "look rotation" message
            var isHit = Physics.Linecast(source, target, out hit); //perfectly fine

            return isHit;
        }

If I add new Vector3(0, 0, 1f) to source (as suggested online "just add a small number", but anything smaller than 1 doesnt "fix" it), the spam seems to go away, but then my LOS is inaccurate, head is a bone on the AI's rig, some values are small but not 0, what could be causing this and why does adding 1 or higher "fix" it? Anything more I could investigate? The point of this code is for my AI to use a LOS check from their head to see for example "if theres a wall between AI and player, assume AI cannot see player, otherwise attack player"

[leaden ice]

my guess would be that source and target are the same

Look rotation viewing vector is zero is basically an error message that happens when you plug Vector3.zero into Quaternion.LookRotation

which can happen if you do lots of weird things like... telling a Transform to LookAt itself or passing V3.zero into Quaternion.LookRotiation or other similar nonsense things

[soft shard]

Strange, that makes sense, but I dont think these 2 are the same, I printed their positions before and they were always different but ill double-check if they are the same object, though they shouldnt be (since I use a LayerMask)

[leaden ice]

well source and target are Vector3s

just print them

see if they're the same when you get that error

[thin hollow]

Yeah, but those are not an option for me sadly, since I live in a terrorist country and do not have any means to pay online for anything.

[crude mortar]

damn..

[thin hollow]

So either something free, or I need to do it myself

[solar current]

God Damn you

[leaden ice]

Is "the object my camera is looking at" really something you need to serialize/save?

The first step to any save system is thiking long and hard about what data you actually need to restore the game state

[solar current]

who can give me talking tom playback what user says

[leaden ice]

anything else is not necessary

[thin hollow]

Well it can be NPC, and NPCs tend to move, so I can't just store the Vector3's of that object position

[leaden ice]

do you need the exact npc position and orientation etc stored for every npc?

What kind of game is this?

[thin hollow]

What? No.

[solar current]

Guys i am not invisible

why you ingore me ?

[crude mortar]

Because you have not said anything worth responding to

[leaden ice]

then you don't need it

think about what you actually need to save

[solar current]

I SAID who can give me talking tom playback what user says

[leaden ice]

for example - let's take Mario as an example. The only things a Mario game needs to save are:

• the completed levels
• number of stars/coins/points
  that's it

think about what your game actually needs

[solar current]

your mother||isfake||

[thin hollow]

But if I load the game and do not restore that reference, camera will have no object to get position from, if these kinds of links aren't serializeable, so it will stay in one place after I load the save.
Also I take my point back - I do need to store and restore NPC's transforms - they aren't stationary and can (and WILL) be in the different part of the level when player press "save".

[solar current]

i am making talking tom clone just i need a script that make him reapeat what user says

CHAT GPT NEVER HELPED ME AT THIS

Hey Hey Hey Hey

-_-

[soft shard]

I guess target.z is 0, but the issue seems to be with source which is not 0, even if I add like 0.3f to z it still causes the messages, anything seem odd from those logs? For context:

Other such situation where I will definitely need to restore the references would be the AI, so that nPC's wouldn't lose the target they were attacking or going towards when game was saved.

issamiyad#0 has been warned.

[trim ferry]

anyways, guys i have an slider variable, but my slider doesnt reference with the variable

and it has the slider component

and i put this in the code

idk what's going on

[sleek bough]

Check that you are referencing the correct type and mixing it up with UI toollkit objects

[trim ferry]

i am

[soft shard]

The inspector in that pic thats trying to reference your slider, is that from a prefab or an object in the scene?

[trim ferry]

i even tried creating another slider

but it doesnt work too

[trim ferry]

prefab

i got it from an asset

[soft shard]

Ah, that might be the issue, prefabs cannot reference scene objects, since theres no guarantee the scene would ever be loaded or the reference would be consistent

[trim ferry]

so what do i have to do

i mean, i unpacked the prefab

bruh

i got it

it was on the prefab folder 💀

i forgot abt tht

[sleek bough]

@trim ferry They are typing presumably answer to your question, have some patience and don't spam

[trim ferry]

im not spamming? i think
im just telling that i solved it

wait, now that i have put back in the prefab folder my reference disappeared

[sleek bough]

When you spawn prefabs at runtime and you want them to reference scene objects, have your instantiating script pass needed references to them

[trim ferry]

ok

[sleek bough]

Here's the basic example of this https://unity.huh.how/programming/references/simple-dependency-injection

[trim ferry]

Ok, I will try, but i remember that my last project i made a turret and i got this mechanism right, but i just dont remember how..

[soft shard]

This slider looks like a health bar, is your goal whenever something causes health to change (ie: take damage, heal, spawn, etc), you want this script on your prefab to update the slider in your scene?

[trim ferry]

man

you are a genius

when i was working on my last project, i created a script for UI Managment, you made me remember it, thank you

[pure cliff]

Since prefabs are sort of ephemeral, I try and avoid doing Dependency Injection on them, and instead approach it upside down.

Instead of injecting FooService into MyPrefab, I have FooService modify the prefab.

Cause 1 service mutating 100 enemies is typically a lot better than injecting that service into 100 enemies individually

[hard viper]

I'm having issues with the collision system in getting contacts.
When my player goes very fast, and clips into the wall, the game gives me a contact point (red X) OUTSIDE of both the player and terrain colliders. Why does this happen?

what my code does to generate the green point (coordinate to check) is:
-Get closest point to contact point inside the ground collider
-If normal vector is pointed away from player, flip it.
-Move a bit into object against the normal vector.

but the contact points it gives me are so screwey, I need to do a lot of correction just to get a point that isn't terrible

like... how much logic do I need to tack on to unity engine's basic physics just to find out what tile i'm touching

[trim ferry]

is this gonna work?

i hope so

[soft shard]

Personally, I dont think a UI manager should be attached to the player, I like to make them either have a static reference, or setup a static broadcaster to pass events around without needing calls like Find, if your spawning your player in, you could even setup a static event for when your player spawns that the UIManager listens for

[deep cobalt]

@crude mortar @thin hollow
Hey guys, still not sure if you can get the model and components to be at the root of a prefab.
When dragging and dropping a model into the scene, Unity adds an empty game object as the root, I am not sure if this is normal, I want to figure out it's possible for the model and components to be in a single gameobject.
Any clues? thanks

here's a video of that

[pure cliff]

With a full Dependency Injection stack I just end up with all my services being POCOs, with a single MonoBehavior as the entry point for Update() that cascades all the way down the tree

And then at the very bottom I have a service that is in charge of keeping track of my prefabs that have been created and acts as the API for managing em and doing CRUD

[hard viper]

pixel, I have a big issue with collisions, if you know about how contacts work

[pure cliff]

For the record though I have over 10 years experience with C# I got about 4 weeks experience with unity :x

[hard viper]

My goal is to, on collision, figure out what tile on a tilemap I collided with. Problem: sometimes the contact point makes no sense!

[pure cliff]

But I think your issue is perhaps continuous collision mode I think it's called?

[hard viper]

red X = the contact point

I'm not exactly sure what continuous collision mode means

[pure cliff]

On your collider I believe there's a checkbox for continous mode or something? It's higher resource cost but handles collisions more precisely for high speed objects

[hard viper]

what

[pure cliff]

Just to confirm can you put a mark or something on the pic where you expect the collision point to actually be?

[hard viper]

he was in discrete mode

in that pic, pink blob was moving up

[pure cliff]

Aight, and are you hooking into event method or polling on Update()?

[hard viper]

event method

I'm testing now, and I haven't gotten any errors since putting im into continuous mode

sry for delay while you're helping. I think you may have gotten it tho

[pure cliff]

Ah yeh, continous handles "mid frame" collision math

[hard viper]

god damnit

ty so much. I would have never figured that out

nothing online covered that

[pure cliff]

First response for "unity prevent high speed wall clip" gives the answer :3

Coding is 99% Google fu haha

1% suppressing your urge to fall asleep in meetings >_>;

[hard viper]

I've been looking for something like that for weeks. ty

I'm mad that the solution was a checkbox, and happy that it was a checkbox

[hard viper]

@pure cliff ty so much. massive help

that also fixed so many of my other issues T.T

[young bridge]

Hey. I've got a question about Jobs. I don't hully understand how to treet them. Are they more like Coroutines in that they will run for multiple frames until they are done? Ore they more like Updates as in they just calculate a single frame? How shell I work with them? I'm asking because I've read that they can't grab deltaTime and needed to be fed deltaTime from the outside. That makes them more like Updates than Coroutines.

[fervent furnace]

jobs is unity version of multithreadings

[orchid bane]

Why does it equal null?

var provider = gameObject.AddComponent<MonoProvider<T>>();```

[lean sail]

What's the error telling you

[orchid bane]

provider.value = component;
on this line
NullReferenceException: Object reference not set to an instance of an object

[lean sail]

Use the debugger to step through and look at the values

Itll save you a lot of time

[young bridge]

Yup, but there are a lot of practices in multithreading. You can start an actual Thread that works infinitelly until you stop it manually, sort of a parallel loop. There are Tasks that work until they are done, which may take a lot of time. Or you can just multithread a single frame, as in spread tasks performed in current frame to multiple threads, but it's still just a single frame. What of all I've described sounds more like Jobs?

[fervent furnace]

the last one, i use job to handle lots of requests at one update
idk is there long running background job since it is quite difficult to transfer data between different jobs and main thread

[gray mural]

sqlite database is unavailable for users until changes are written in db browser, right?

that's code question

[knotty sun]

that's a complete nonsense question

[gray mural]

why.

[knotty sun]

read what you have written

[gray mural]

I get an error when changing database manually and not writing changes.

SqliteException: The database file is locked
database is locked

it cannot perform any actions until changes are written there

[knotty sun]

how can you 'change the database' and at the same time 'not be writing the changes'?

[gray mural]

I have written "changing database manually"

not via code

it's disposed there

it's performed so that it's correctly disposed

[knotty sun]

either way, if you are changeing something you are writing the changes no matter how you are doing it

[gray mural]

no.

I am disposing database when writing chages via code

if I change table manually, I have to write changes

and when changes are not written, I cannot perform any further actions in code

[knotty sun]

do you mean commit the changes?

[gray mural]

no, write the changes

[knotty sun]

then you have no idea what you are doing

[gray mural]

"write changes", as you can see on screenshot I have sent

[knotty sun]

are you doing DDL or DML ?

[gray mural]

yes

SQLite

[knotty sun]

there is an or in my question

[gray mural]

both

currently using DML

I am inserting data in the table

[knotty sun]

so when you use DML to make changes to an SQL database you have to commit those changes to makes them fixed

[gray mural]

I have mentioned that they are commited via code.

If changes are done manually, you have you commit them manually too

and while they are not commited, I cannot run my script

that's what I am trying to say

[knotty sun]

it does not matter how you make changes the mechanism is the same

[gray mural]

yes, but they are commited via code when using closed using

[lean sail]

It's always committed via code, just not your code when you do it manually

[gray mural]

yes, I have to save them when I do it manually

also it seems than running 2 examples of this code causes an error too

but I cannot test it

because I don't know how

I can just test running it via code and manually

[knotty sun]

which would tend to suggest that you open the database for exclusive use

[gray mural]

I am sorry, I don't get it

[knotty sun]

SQL databases are multi user.
when one user changes something using DML those changes are visible only to him until he issues a commit.
If you have 2 processes which are locking eachother out then you must have the database open for exclusive use only

[gray mural]

I see, I'll look into that

thank you

[lean sail]

From what I remember yesterday, you said this was for users saving levels right? You ideally dont want users to even have direct access like this anyways

[gray mural]

of course I don't want

I don't mention saying that I want them.

but what do you even my by direction access?

[lean sail]

Then there should just be 1 thing writing to the database anyways

[gray mural]

I will just add levels into database when they save them

[gray mural]

what if 2 users have created level simultaneously?

[lean sail]

Neither user should have direct write access

You'll quickly get people writing bad things, or just spamming to fill it with a million entries

[gray mural]

yes, of course.

You can I even come to idea to make them able to change that.

I want to change it via script when they save level

[knotty sun]

doesn't really matter because SQLite is not a server viable database anyway

[gray mural]

they will just create level with my game

and when they click "save level", I have to load that level to database

ideally to their profile

anyway, I think I should make databases for more than 2 hours

I gonna look into that tomorrow, thank you both for your help and time

[ivory ginkgo]

I have a TickManager, which can have various ticks, like music (qtr, half, etc). One of my entities needs to change it's tick on the fly based on it's state. So my question revolves around the tick actions it subscribes to. Should Actions only be subscribed to once (like in OnEnable)? If I set Manger.Instance.OnTick += TickAction every Tick (via a SetTick method), would it subscribe more than once?

[lean sail]

not entirely sure what you mean by the first part of the question, but yes it will subscribe more than once if you keep adding it

[ivory ginkgo]

Okay, then that means I need to change my approach for an entity that needs to switch between two tick actions. I'll just subscribe to both in OnEnable, and put the logic for Tick type with it. Thanks.

[ivory ginkgo]

I initially thought something like this would work, but instead, I'll just subscribe to both, and put logic for which Tick to do.

protected override void OnEnable()
{
    SetTick();
}

protected override void TickActions()
{
    SetTick();
    // do some other tick stuff
}

private void SetTick()
{
    if (_baseEntity.IsPowered)
    {
        TickManager.Instance.OnEighthTick += TickActions;
        TickManager.Instance.OnQuarterTick -= TickActions;
    }
    else
    {
        TickManager.Instance.OnEighthTick -= TickActions;
        TickManager.Instance.OnQuarterTick += TickActions;
    }
}```

[lean sail]

each entity can keep track of which one its subscribed to (like which interval its running on) then just unsubscribe from that, while subscribing to the one you want

doesnt even matter as well if its not subscribed before trying to remove it
https://dotnetfiddle.net/JA6TYy

subscribing to both will still require you to keep track of which interval its running on, so might as well just subscribe to the right thing rather than subscribe to all and ignore the ones u dont want

[ivory ginkgo]

yes, but if, for example, IsPowered is false for X ticks, will it then start running TickActions X times per X tick? (since in my code case, it would subscribe to the same action every tick)

[lean sail]

oh i just noticed that you are calling SetTick() inside the other functions, yea u really dont want to do that

im confused as to why you need that inside TickActions()

[ivory ginkgo]

I don't necessarily. I was initially asking if it would subscribe more than once. Since it will, that means I need to only subscribe once to both in OnEnable, and remove SetTick altogether, then put logic within this file (either separate TickActionMethods or something) to know which tick action code to run.

[lean sail]

you dont need to subscribe to both is what im saying, because that logic for "know which tick action code to run" can just be applied to subscribe to the correct delegate. Instead of calling SetTicks() everytime, just only call it when you need to actually change how its tick system

if the tick system hasnt changed, you dont need to call it

[ivory ginkgo]

In other words, in SetTick, just add a condition to check the last tick state - so it won't up the subscribes each tick.

[lean sail]

no, just dont call SetTick if you dont need to

if the condition for swapping tick systems is isPowered being changed (true/false), then everytime its changed, subscribe to the correct delegate

you could even make this a setter, if the value has changed then subscribe/unsubscribe. If it hasnt changed, do nothing

[leaden ice]

Using SOs you wouldn't need the switch statement at all

that depends

how different is the behavior

Let's say the difference in behavior is that one enemy waits 10 seconds before attacking and the other waits 5 seconds

that's easily expressed as a variable

They are not mutually exclusive

For example I made a tower defense game

[latent latch]

I use switches a bunch, especially for my ability system I've been making. If it's just a one time instantiation of data I don't think it'll matter that much.

[leaden ice]

my towers are defined by ScirptableObjects

things like Range, rate of fire, etc. are easily expressed as normal variables

things like "targetting strategy" are enums

and for those enums ultimately a switch statement is choosing a delegate to use to determine which target the tower will prioritize

actually I guess that's not inheritance 😆

[latent latch]

Yeah, but then you run into stuff like firing modes, like does it fire in a random range, or is it a fixed value

[leaden ice]

sure and unity's particle syustem is a good example of how to handle that

[latent latch]

im not too sure how it's handled under the hood

[leaden ice]

with stuff like https://docs.unity3d.com/ScriptReference/ParticleSystem.MinMaxCurve.html

[latent latch]

I expect it to be a billion bools like the gui itself lol

[leaden ice]

you can reference the SO from anywhere

yes

use it in multiple places

make a list of them

reduce the numnber of prefbs you have to manage

[latent latch]

they're useful for caching a single instance of data to read from

[rough crystal]

Hi, not a code question but not sure what the correct channel is. Using unity recorder to take a screenshot and I don't have an alpha checkbox. This should only be excluded in GameView or JPEG format so any help would be appreciated.

[storm copper]

Is there a way to push a nav mesh agent?

Everytime I addforce to it’s rigid body it just freaks out and shakes a bunch

[neon glen]

all you need is a reference to the agent then do agent_Ref.destination = the_Vector_3

[spring creek]

I think they want a physics reaction, like knockback.

@storm copper , you'd probably have to disable the agent first, then reenable it after the addforce

[neon glen]

ahh my bad

[bright token]

Hello, I've started a little game a while ago but had to take a break because of an annoying problem, which I still cant solve. Its about a currency, that you pay in the ingame shop to buy character packs, but my code that checks if this currency is 1 or more doesnt do as it should. The currency amount just goes into negativity and the player can buy infinite amounts of packs. Im using a datahandler, that saves the data in a file and I think the problem is, that somehow this data doesnt get updated in time and still thinks, that the amount of currency is the one it started of with, not the one it is after being used.

For code reference, please ask, because theres too much to simply paste in :) thanks for the help!

Ah I got it working

[zealous arrow]

hi! Does anyone know how to fix this error "Error building Player because scripts had compiler errors"? I was trying to build the game. What I read online is to move any script that has unityeditor in it to an editor folder but how do I even find out which scipt has it without opening one by one. Any ideas?

[spring creek]

What do the errors in the console say?

bottom bar in unity

click it to open the window

[leaden ice]

the errors in the build will tell you exactly where the issue is.

[zealous arrow]

All it says in the console "Error building Player because scripts had compiler errors" is there a way to access more detail then the console anywhere? It is not specific at all

[quartz folio]

There should be other compiler errors listed

[zealous arrow]

All I see is this:

[leaden ice]

look at the one right above that lol

it tells you exactly

[zealous arrow]

Do you think that one is the issue? It has nothing to do with the player

[leaden ice]

of course it is

[quartz folio]

yes

[zealous arrow]

Hey I will take it haha

[leaden ice]

very obviously so

[quartz folio]

UnityEditor code doesn't exist in the build, you cannot use it outside of editor contexts

[zealous arrow]

so do I just move that script to an editor foflder?

[leaden ice]

When it says "Error building Player" it means the Unity Player aka your game. Not the Player object in the game

[zealous arrow]

ah!

[leaden ice]

doubt it - that's probably an essential script for the game if it's called "PressurePlateScript"

[quartz folio]

Regardless of that, it's an error, a compiler error, exactly the type of thing it was saying was the issue

[leaden ice]

you need to remove any reference to UnityEditor stuff from it

or wrap UnityEditor stuff in a preprocessor directive

[quartz folio]

Presumably there's no good reason for it to be using UnityEditorInternal

[leaden ice]

yeah I'd guess it was added by accident

[zealous arrow]

oh so just remove that "UnityEditor" line?

[leaden ice]

if there's no reason for it being there

then yes

[zealous arrow]

hopefully that is it. It was calling "// private void Update()
//{
// options = UnityEditorInternal.InternalEditorUtility.tags; // Get all available tags from the Editor
// }" so I just commented it

that is the only place I saw UnityEdtor mentioned

[leaden ice]

yes that seems likely

[zealous arrow]

thank you! well it has been .48 seconds and it is still going so that did fix something. thank you very much!

[spring creek]

It's not ALWAYS the case, but I try to solve errors from top to bottom (which is chronological order), because often one causes the next. Even if they seem unrelated

[zealous arrow]

ah I see! I didn't know that! thank you for the tip!!!

[dense tusk]

oy lads, i've got a script that gets added to an object the player has picked up, and i'm trying to have it instantiate another object when it collides with a trigger. my struggle is getting the reference to the object that i want to spawn when the script doesn't start on the object that gets picked up. is there a way to do that?

[leaden ice]

Why are you adding a script to the picked up object?
How would you like to determine which object should spawn when it collides?

Can you just reference the prefab from the pickup script on the player and propagate it from there?

[dense tusk]

1. so i can have the object check for a collision, and only that object check for a collision. i figured it would be bad practice to have several trigger objects all check for the same collision.
2. if i can figure it out, i want to do that via code. like how you can do GameObject.Find("dadada")
3. possibly, but i'm trying to see if i can do it without adding more to the player's scripts. what i'd like to do is just have the player add the script to the object, and then the object will decide what object to spawn based on what it collides with

[halcyon venture]

how can i change the width of an image (in pixels) via a script?
like :
myimage.width = whatever;

[spring creek]

1. is confused, When you said "gets added" did you mean in code, or on a prefab? I assumed the former by the wording, but that wouldn't help with what you're saying. What does the first line in your first point mean?
2. I'd recommend having a script on the pickup object with a prefab to instantiate instead of finding it. But that IS how you find (https://docs.unity3d.com/ScriptReference/GameObject.Find) things. You need the exact gameobject name
3. Maybe add it to the object being picked up? Then the player gets the trigger event, checks if the object has that script and calls the spawn method from the script?

[thin hollow]

Can somebody help please? I've read the https://docs.unity3d.com/ScriptReference/SerializeReference.html
but I can't quite still understand it... Suppose I have a custom struct that has a reference to a Scriptable Object asset in it (in this case - one that stores data for items properties in the inventory component):

    public struct InventoryItem
    {
        public string id;
        public ItemDefinition def;
        public int amount;
    }

Do I need to mark def variable of struct with [SerializeReference], or I need to mark the whole struct, or it's all fine actually and I do not need it?

[prime sinew]

Please don't cross post

[ashen yoke]

thats not what SerializeReference does

by default unity will serialize anything that is not UnityEngine.Object by value

so if you need to serialize a reference to a c# object you use that attribute

ScriptableObject already is serialized by reference since its a uobject

[thin hollow]

Ah, okay thanks!

[dense tusk]

1. correct. the script gets added to the object via code from somewhere else. i have a player object that can pick up an object that it's looking at, and when the player picks up the object, it adds a script to that object.

2. using that command only works for active game objects. that's just an example of what i'm trying to do. i thought maybe there was a similar function that does that, but just finds it in like, the assets folder. i'm trying to spawn an object that doesn't exist in the scene, and if possible i'd like to avoid storing references to these objects in the player's scripts just to pass it along to another script. i just want to see if i can do it another way.

3. that probably would work, but i'm trying to do this object spawning from outside the player object.

[ashen yoke]

simplest way is to have a singleton scriptable with references to whatever assets you need

but since it will require that scriptable to be in Resources, it will lead to longer startup times

[leaden ice]

2. I didn't mean do you want to do it via code I meant... how are you deciding? Is it a property of the player? Is it due to some weapon equipped to the player? From a gameplay perspective what determines which thing should be spawned?

[dense tusk]

my bad, misunderstood the question. the thing i'm choosing to spawn is determined by the trigger the object collides with. ex; if i have the object collide with a door that has metal door hinges (with triggers on those hinges), i want it to spawn a particle system thing i've made to look like sparks have gone flying

think that answers the question better

i'm able to check for the collision with that specific type of trigger, so i know that part works properly. it's just getting that particle to spawn that i'm having trouble with

[cobalt gyro]

can you get a NullReferenceExeption while setting a variable

[ashen yoke]

show the code that throws

[cobalt gyro]

points[i] = new Vector2(Random.Range(0,width), Random.Range(0,height));```

[ashen yoke]

yes array can be null and you are not setting a variable

you are accessing the array indexer

[] < indexer

which is a method

[cobalt gyro]

ty

[lean sail]

shouldnt that be a index out of range exception

[ashen yoke]

nothing can throw it if the array is null

[lean sail]

ah true

[cobalt gyro]

i ran the code and it crashed the editor

missed an infinite repetiton

[leaden ice]

you put put a component on the door that has a reference to the sparks prefab

basically a "COllideWithMeParticles" component

that goes on these various objects

[thin hollow]

Clarification, same goes for references to a prefab in assets (for spawning those), right?

[dense tusk]

that's a big brain solution. that way i could do something like desiredParticle and just have that be different for each object. then the object that spawns the particles can spawn whatever that variable references

[leaden ice]

yep

and all you have to do is throw that component on the object and forget about it

and the projectile script just looks for that component and spawns whatever

[dense tusk]

i didn't even think about having the trigger object having that component

thanks lad

[ashen yoke]

reference to gameobject, which is also uobject

anything extending UnityEngine.Object is considered an asset that can be written to disk, and has a guid/local id

which is used to serialize it and retreive it

[obsidian saddle]

i literally said it was affecting my game though💀

like its whatever, i restarted my computer and now everything's fine

but it did affect my game

[somber nacelle]

that error was unrelated to your game at all. it was specific to the unity editor, you most likely had the animator window or some other graph editor window open

[brittle sparrow]

look at this monstrosity of a nested process

[quartz folio]

Please cache things instead of repeatedly accessing them

[brittle sparrow]

well.. maybe if i leave it in the corner and pretend it never happened

that's what i always do

a good example is my special multi-type list class

it's probably 1000 lines of code

[quartz folio]

Or just spend the 10 seconds it takes to refactor the repeated access away

[brittle sparrow]

a fraction

[timber cloak]

Got a problem with rounding. Theese are different chunks. with my current code i take the worldPosition/chunkssize(21 in this case) and get the chunk. It works most of the time but in one senario when I am pressing chunk 2 at the line neghbouring chunk 1. I get the pos .5, 10.5 with the mathf it becomes chunk 0,0 but it should be 0,1.

The math makes .5 position to 0.02 that's rounded to 0. While 10.5 becomes .5 that should be rounded up but rounds down to 0

[brittle sparrow]

wow, upon measuring it it's like 3x or 4x the scroll length

i was actually unsure on how to even work around this but as long as it works

[prime sinew]

Ok. Did you have an issue you need help with?

[brittle sparrow]

nope

[prime sinew]

Okay

[quartz folio]

please

[brittle sparrow]

oh, in this specific example i was actually working with nested classes where their types differ,
so like in a World i contain a bunch of Continents and in a Continent i throw some Regions etc

[quartz folio]

why does that matter at all

[brittle sparrow]

i could just make an access func to make it more readable

[quartz folio]

the indexer is the access you are repeatedly calling

[brittle sparrow]

i would have to do like MapWorld[i].MapContinent[j], not sure how to store that like shown above

[quartz folio]

you don't need to access MapWorld[i] 15 times, you just have to do it once

[lean sail]

https://docs.unity3d.com/ScriptReference/Mathf.Round.html
the docs explain what it does at 0.5

[brittle sparrow]

but the access func would definitely work

oh so i just cache it into something called mw to make it fast?

sure lemme pull that one

although the monstrosity looked nice too

[quartz folio]

Just get your IDE to create the variable (if it can do that). If you don't know what type it is, you can manually just write var, and your IDE can definitely convert that to an explicit type too.

[brittle sparrow]

oh, my IDE's raw

it's been raw forever so i'm used to it though

like, nothing's setup

[quartz folio]

Jesus christ

[brittle sparrow]

[quartz folio]

Well, do note that you can't ask code questions on this discord if you have an unconfigured IDE, because it's completely disrespecful to people's time.

[brittle sparrow]

i understand

on another note, how's this looking?

don't think it compresses any further

[quartz folio]

way more reasonable

[brittle sparrow]

yeah i think i like it better now

think i'll avoid monstrosities like before as much as i can from now on

even if they get tucked away anyway

[fringe ridge]

what's the proper way to hold references to a bunch of prefabs that will be used some time in runtime? It feels like have a [SerializeField] list on a random script isn't the best practice

[prime sinew]

Nothing really wrong with it tbh

What do you mean by used some time? Like there's a chance they won't be used at all?

[fringe ridge]

they're used for creating base level on start, and then when the game restarts used again

[prime sinew]

That seems fine. If you want to have different "sets" that might make things easier to organize, maybe use ScriptableObjects instead?

I'm assuming the number of prefabs is large

[elder flax]

lets say I wanted a spaceship like the one in Cosmoteer

as in its made of a ton of tiles that can disconnect and float freely when whatever is connecting are destroyed

also the whole thing should act as a physics object

what would be the best way to do this?

could I use physics2d and link all the tiles together when the ship is spawned

or is there a better way

[swift falcon]

Is there nay help chat here?

[winged mortar]

These channels are meant for coding questions, so ask away!

[swift falcon]

how do i make the door not cast shadows on the walls?

i want the door to only cast shadows on everything except the walls

[System.Serializable]
public class MapScene
{
  public bool isTown; // if this is True, then show the variables below
  public Vector2 spawnCoords; // when you open your save and load the game, you spawn here!
}

Hello! I was wondering how the above could be done! I remember seeing it somewhere, forgot where though, maybe in SpriteMask Components?

If isTown is true, then in the Unity Editor itself, in inspector it'll show the variable spawnCoords, otherwise it won't

it's purely visual but is still nice to have!

Hey there. Not sure in what channel multiplayer help goes but ill ask here;

My syncing isnt looking right. I am using the Relay system with Untiy's netcode for GameObject

The players stay up in the air for some reason.

[simple egret]

#archived-networking would be your best bet

[pastel rivet]

I'll try there, thanks!

[winged mortar]

Multiplayer discord also a good shout

[livid sandal]

Hello, i wanted to add this data to store in a scriptable object but it doesnt show in the inspector is this type of data possible to implement in scriptable object? if so what did i do wrong? Thank you all for your help,

or is there a better/correct way to do this? please let me know 🙏

[simple egret]

Try marking the PerWave class as serializable, using the [System.Serializable] attribute

Also if you're planning on using the PerWave class outside of WaveData, it should be in its own file

[rancid frost]

  Shader "Example/TestShader" 
  { 
    SubShader {
      Tags { "RenderType" = "Opaque" }
      
      CGPROGRAM
      #pragma surface surf Lambert
      
      struct Input {
          float4 color : COLOR;
      };
      
      void surf (Input IN, inout SurfaceOutput o) {
          o.Albedo = 1;
      }
      
      ENDCG
    }
    Fallback "Diffuse"
  }

Why does this default surface shader turn pink?

[simple egret]

Ask in #archived-shaders

[rancid frost]

sorry 🫡

[rancid frost]

Add the system.seriable

[livid sandal]

Thanks, works like a charm, one more question tho, can i use Dictionary in scriptable Object? i tried using System.Serializable it doesnt work

[simple egret]

Unity doesn't support Dictionary serialization

Any complex collection, really

[rancid frost]

you can however use 2 lists/array

[fleet shell]

Alright, feel like I am going insane on this one and I've been up all night working so could use a 2nd pair of eyes. As seen in the screenshots below, I am using a PerlinNoise generator to display on to a dynamically rendered mesh, however, although the PerlinNoise can accurately take in the size parameters of the mesh, when applying the noise to the texture of the mesh, it only shows 1 section of grey noise and not the entire thing.

Code snippets also, probably somewhere I am just not applying the X and Z correctly.

[hard estuary]

Have you set UV for each vertice? If every vertice has the same UV, then everything will have the same color.
