Surprisingly none of my assets are above 100mb each

Total project size is 26gb

[grave frost]

you paid then? You have to just pay for a premium account right?

[fluid kiln]

yep its not abt the dialogue itslf, but the triggers, like speaking to an npc, entering a scene, stepping into a certain area, getting an item... ecc ecc...

(the trickiest part is the one that checks if the player has achieved X things in the story)

[eager spindle]

I don't have lfs on as my files aren't >100mb each

Even though the repository is 26gb

[grave frost]

I meant for disabling pushing to main

[eager spindle]

There's a setting in GitHub for that uh

Branch protection

Yuh

[grave frost]

Yea you can't enable it with a regular repo

[rocky canyon]

well if that isn't present then i wouldn't consider it a real dialog system

more of fluff at that point 😅

[eager spindle]

Box collider with trigger
Attach a script that takes in a serializable object where on trigger enter, it plays the lines stated in the serializable object

[grave frost]

Also that's still really large.... i'd say over 15-20mb it should be added to lfs. We baked lighting though, so we had one file that was like almost 2 GB lol.

Total project size for us: 58 GB

Build size: 2 GB

[eager spindle]

And also track that the dialogue has already been played before in your save file

[eager spindle]

School project so I don't really care what GitHub thinks

We don't even bundle our assets

[grave frost]

You say that and then one of your files you pushed gets corrupted or something

[eager spindle]

Hasn't happend yet

[grave frost]

You regularly bundle your assets?

[eager spindle]

Tbf I've never made a project large enough to justify bundling my assets

[rocky canyon]

whats bundling ur assets mean?

[eager spindle]

Even my genshin ripoff was only 400mb despite having a lengthy campaign

[fluid kiln]

yessir i agree, but what if i need a dialogue to trigger under super specific conditions? do i just make a personalized script? Is a bunch of ifs the best way?

[rocky canyon]

simple trigger colliders.. that call a function within ur DialogManager class

[eager spindle]

let's say you're making genshin impact, big open world RPG with lots of assets.
but you can't load 60gb of assets at once

to bundle your assets means to place them in files that get loaded at different times. if you're in one region then the files for that region get loaded and the rest remains unloaded to save ram

It's very important for console because consoles have very little ram 😡

[rocky canyon]

NPC: Billy VISIT: #4

[rocky canyon]

ohh okay.. yea makes sense

AAA kinda stuff

Loading Shaders

[eager spindle]

also helpful for sharding downloads for your game

[grave frost]

Oh we're talking about Addressables here huh?

[eager spindle]

just a brief summary

[rocky canyon]

/woosh

[eager spindle]

I haven't touched it much because I don't make big game

[rocky canyon]

that 1 thing i haven't even had secondary exposure to

[eager spindle]

Everything I have is low poly

[rocky canyon]

Same! 🤜 🤛

[eager spindle]

including my skibidi toilet fan game

[rocky canyon]

lowpoly-ftw
not b/c i can't model..
but b/c i can't texture 😄

[grave frost]

I would probably suggest using the newer Addressables system rather than asset bundles directly

[eager spindle]

I feel like my method is hard coded but yea having triggers that read scriptable objects for dialogue does wonders

[grave frost]

Substance Painter go brr

[rocky canyon]

well, i can texture.. but im bad at UV mapping

[grave frost]

womp womp

[rocky canyon]

wanna hook me up with a subscription 😈

theres 1 that u can compile urself for free i believe

[grave frost]

no cus i dont have one lol

[rocky canyon]

ArmorPaint

[eager spindle]

Tldr I have QuestManager.AddObjective, either takes in Dialogue which plays dialogue, Position which places a marker and asks players to go to a location, Entity which asks player to kill enemy(ies) and Puzzle

This Quest manager is independent of CampaignManager

[rocky canyon]

https://armorpaint.org/ this one is free if u compile it yourself 🙂

[rocky canyon]

sounds solid

[eager spindle]

this is fine imo

I enjoy low poly games a lot

[rocky canyon]

ya, im growing tired of flat shaded models tho..

[eager spindle]

as a Roblox child

[rocky canyon]

i'd like to adda bit of texture here and ther..

[eager spindle]

can't you texture in unity?

[rocky canyon]

ya, but only when the UV's are decent

thats my issue..

[eager spindle]

if you're daring enough you can make submeshes and do the base map in unity

[rocky canyon]

not the texturing.. but the UV mapping

just havent learned enough yet to be good at it

[eager spindle]

you can start small ig make submesh for the walls of the barn and put some stock texture

I don't really 3d model I just paste cubes in the scene and call it a day

[rocky canyon]

https://www.thebasemesh.com/ not sure if ur familiar. but this is a great asset

all of these come with great UV's

[eager spindle]

Ooh

Right now I'm using Womp3D for my more complicated models

Very fast to get into

[rocky canyon]

thats what i use to practice my texturing for now... and once i feel comfortable doing that.. i'll have more context to use myself.. when trying to layout good UVs

b/c its not that i can't UV its more like I don't know what good UV's should look like..

i'll just Smart UV unwrap everything! 🤣

[eager spindle]

sounds revolutionary

[rocky canyon]

but anywho, i believe we've went offtopic a bit 🤏

🤫 i'll be quiet.. just waiting for some code related questions lol

[eager spindle]

right now I'm thinking of server side implementation to store user data, I'm making a small project right now and am lazy to set up firebase

how secure is making an in-memory database in python flask? user passwords will be hashed with bcrypt

[rocky canyon]

i'll probably just try to contend with this error for a while

[rocky canyon]

i've never used flask for anything but webdev

does it have an API that unity can use?

[eager spindle]

you can send POST/GET/FETCH requests with unity networking

which flask does

[rocky canyon]

well is anything ever actually secure?

i do know 1 thing.. server-side is hella lot better than client side

soo u got that going for ya

[rocky canyon]

soo basiclly a www web request type thing?

[eager spindle]

Yep

[rocky canyon]

i haven't much experience with those outside of setting up a Mirror lobby

i should experiment myself

[eager spindle]

the database
Dictionary<int, string> passwords; // user passwords hashed with bcrypt

Dictionary<int, Inventory>; // user's inventory
struct Inventory {
int coins;
List<item>
}

in theory this is secure

but people absolutely despise me for this implementation

[rocky canyon]

why is that?

[eager spindle]

no one uses flask to make an actual backend they keep saying it's for learning purposes

and to go use a proper backend

[spiral narwhal]

        private static IEnumerator LoadGame(GameStateModel modelToLoad)
        {
            var operation = SceneManager.LoadSceneAsync(modelToLoad.CurrentSceneName);

            while (!operation.isDone)
            {
                yield return null;
            }
            
            GameSaveService.LoadGameState(modelToLoad.FileNameWithoutExtension);
        }

Is there a way to do this statically

Because StartCoroutine does not exist in a static context

[eager spindle]

you want to do this across scenes?

[slender nymph]

you can start the coroutine from a non-static method on a MonoBehaviour, such as in response to pressing a Play button

[eager spindle]

This object will die during the scene switch

Put it in donotdestroy

[spiral narwhal]

I do want it from a static context

[eager spindle]

❌

[spiral narwhal]

But StartCoroutine does not exist

[eager spindle]

you can make a public static instance though

[slender nymph]

why

[spiral narwhal]

Easy service integration

If there's no way to make it static that's ok

Just making sure

[slender nymph]

then either make a persistent gameobject that you can start the coroutine from or don't use a coroutine

[spiral narwhal]

Do I HAVE to use a coroutine for just "waiting" while loading?

[eager spindle]

public class GameLoader:MonoBehaviour {
  public static GameLoader instance
  Start() {
    DoNotDestroy
  }
  public IEnumerator LoadGame() {
  }
}

smth like this

[spiral narwhal]

I know what a singleton is haha

[slender nymph]

depends, are you using Unity 2023 or newer?

[eager spindle]

then just Start routineGameLoader.Instancr.LoadGame())

[spiral narwhal]

22 LTS

[slender nymph]

then the only built in option for waiting for that load to complete is a coroutine

[eager spindle]

in addition to loading scene async you can also load it additively, then once it's done you can unload the main menu

[spiral narwhal]

Ah I see

Yeah no it's just simple 2D no need really

But thanks

[eager spindle]

stuff might explode though last time I tried it the engine didn't like me

I'm ngl a lot of loading screens are fake

If you're not loading 8gb of assets or waiting for other players to join you can fake a loading screen

[slender nymph]

just write a static class that will spawn a gameobject with a component that just starts the coroutine on it and marks itself as DDOL. then the static class just keeps the reference to that spawned object for the duration of the session and you can change scenes using that

or you could use a singleton, but that would require putting it in a scene manually or lazy loading it which is basically the same thing i just described anyway

i personally prefer the static class option because then the monobehaviour can be private so nothing can access it directly without some wacky shit like Find

[eager spindle]

imagine using Find in production

[mystic dawn]

can anyone help me figure out why my enemy movement script is not working?

my enemy keeps just moving up and down and does not follow the player at all :((( i've set up the entire enemy script and everything works correctly apart from moving the enemy

https://gdl.space/lolaqufidu.cs

[slender nymph]

what is the target field assigned to

[wintry quarry]

yeah that code doesn't make sense

seems like it shouldn't even compile

[eager spindle]

you're setting your own RB velocity when trying to move the enemy

[wintry quarry]

Vector2 direction = (target - (Vector2)transform.position).normalized;```

but yeah it's unclear which script this is

or what object it's attached to

or what the variables are assigned to

etc

[mystic dawn]

i think i found it as i sent the message it's so dumb im ashamed of saying what it was

[eager spindle]

[mystic dawn]

i checked the freeze x on rb

by accident and forgot it

[rocky canyon]

whats wrong with that?

    IEnumerator BootEnvironments()
    {
        FindLightController();
        yield return GetRandomWaitTime();
        environmentProgress = 100f;
        IncrementSector();
    }

    IEnumerator BootSystems()
    {
        FindGamePlayObjects();
        SetupSettings();
        yield return GetRandomWaitTime();
        systemsProgress = 100f;
        IncrementSector();
    }

    IEnumerator BootGameSetup()
    {
        SetupPlayer();
        yield return GetRandomWaitTime();
        gameSetupProgress = 100f;
        IncrementSector();
    }``` 😄

eventually i wont need to fake it 🤣

[eager spindle]

🎊

Ooh

LMAO

[rocky canyon]

but u can tell from the video its soo fast.. b/c i reduced the GetRandomWaitTime() to zero

[strong wren]

how can i check if a value is going down in an if statement?

cause if(value--) doesnt work

[wintry quarry]

if (value < previousValue)

[strong wren]

that will just check if a value is smaller then another value

[wintry quarry]

yes

and if that "other value" is the previous value of the variable

then we know it's "going down"

you asked quite a vague question btw, so I'm answering to the best of my ability with the given context, which was basically 0

[strong wren]

ok leme explain more

[eager spindle]

You mean to say that if the value now is less than the value last frame?

int coins;
int coinsLastFrame;

Update() {
if(coins < coinsLastFrame) {
}
// other logic
coinsLastFrame= coins // make sure this is last
}

depends on what you're doing

[wintry quarry]

Yes^ in other words if (value < previousValue)

but if this really doesn't answer the question, more context would be nice.

[radiant frigate]

im having an error that says that addforce doesnt take 4 arguments, what sintaxis error am i having? i searched in the docs and couldnt find it or dont understand it

[wintry quarry]

You're looking at the docs for Rigidbody

this is a Rigidbody2D

[eager spindle]

it takes in a Vector3 not 3 floats

do check the examples

[faint sluice]

Also you're supposed to give direction of force in vector format, not separate floats

[wintry quarry]

Rigidbody2D takes two arguments for AddForce: Vector2 and ForceMode2D

[spiral narwhal]

        private IEnumerator LoadGame(GameStateModel modelToLoad)
        {
            Debug.Log("loading");

            var operation = SceneManager.LoadSceneAsync(modelToLoad.CurrentSceneName);
            operation.allowSceneActivation = true;

            while (!operation.isDone) yield return null;

            Debug.Log("finished");

            GameSaveService.LoadGameState(modelToLoad.FileNameWithoutExtension);
        }

"loading" is printed and the scene changes correctly, however, "finished" is never printed, nor is the method unterneath it called. Why?

[wintry quarry]

https://docs.unity3d.com/ScriptReference/Rigidbody2D.AddForce.html Always check docs @radiant frigate

[eager spindle]

scene dies before finished is printed

[radiant frigate]

thanks everyone ill check!

[eager spindle]

you can load it additively

[wintry quarry]

You are probably running this coroutine on a GameObject in the previous scene and since you didn't load the new scene additively, this object went byebye

[eager spindle]

then unload after finish is printed

[spiral narwhal]

Ah so I can simply transfer it to a DDOL object?

[wintry quarry]

You need to either load additively or this object needs to be DDOL

[strong wren]

oh nvm the hting i needed fixed itself out

[eager spindle]

suspicious

[strong wren]

no i confused myself

when i was asking for help

[wintry quarry]

i mean if(value--) was certainly pretty confusing

[strong wren]

im adding sprinting and i wanted to make it so when a person is running or jumping to set the regentimer to 5

and idk why i came to check if the stamina value is going down

[wintry quarry]

yeah that seems roundabout

classic XY problem

[strong wren]

wdym by XY?

like chromosomes? or Cords?

[wintry quarry]

https://xyproblem.info/

basically you actually wanted to know if you were sprinting, you thought you could do this by checking if stamina was going down, but really you should just be checking your isSprinting variable or whatever

[strong wren]

oh

yeo

yep

idk i confuse myself when i am reworking on my own code, so sometimes if i just reread the code then i can easily do it

[fluid kiln]

tysm!

[bronze mortar]

Hey guys, I just wrote a script to spawn a prefab within this range, but it's not spawning anything. Does anyone know why? Yep, the object has a collider and is prefabbed

[wintry quarry]

Is the code running? Make sure with Debug.Log

[bronze mortar]

True :p

[short hazel]

Unless that function is hooked up to an event (like a button click), the "0 references" on top of that in the code should be pretty self-explanatory :)

[radiant frigate]

okay i added force but now he just phases through the wall, i could make a hitbox to tp in him back again but i just wanted to ask if there is something smarter that wont lead me to having to do this each time i use addforce

[wintry quarry]

Which object are we talking about?

The spaceman?

[radiant frigate]

yes

[wintry quarry]

You just need to make sure its colliders are properly arranged

looks like the sprite and collider are not aligned properly

[radiant frigate]

if i allign it it shouldnt phase through the wall?

[eager spindle]

for the spaceman could you show the collider

[wintry quarry]

of course

[eager spindle]

like the circle collider attached to it

[bronze mortar]

I just added this, but the script won't even run... That's weird

[radiant frigate]

this should work then right?

[eager spindle]

show the component

make sure Is Trigger is off

[radiant frigate]

well i will just test lmao

yeah trigger is off

[wintry quarry]

and the collider for the wall?

[radiant frigate]

the wall is a tilemap

and has a tilemap collider

[wintry quarry]

Well do you have an event system in the scene? What kind of object is this script attached to?

[short hazel]

Is that script on a UI object (under a Canvas)? Do you have an Event System in the scene? Does that have a Graphics Raycaster attached to it?

[radiant frigate]

i think the collider is directly related to the grid so i shouldnt or maybe even cant change that

but i might be wrong

[wintry quarry]

you can change it

it's from the tiles

and the colliders for the tile sprites can be configured in the sprite editor

make sure the collision shape is correct for the tiles

[bronze mortar]

It's on this game object

[wintry quarry]

so it's a physical game world object? Does your camera has a PhysicsRaycaster2D?

and again, do you have an event system in the scene

[hollow dawn]

I cant look up or down is there something wrong with my code? https://paste.ofcode.org/yKdjLnwaFD38szFjp7yjr8

[radiant frigate]

but even if it were wrong wouldnt it just stop at the collider point

something like this

where even if the sprites where overlaping

the colliders arent

[wintry quarry]

well for one xRotation -= mouse_Y * verticalSensitivity * Time.deltaTime; you should not be multiplying deltaTime in here

[bronze mortar]

No I don't

[wintry quarry]

but it's more likely an issue of how you set things up in the inspector

[wintry quarry]

well you need one

and also the physics raycaster2d on the camera

[bronze mortar]

How do I add an even system? I'm a little unfamiliar with that

[hollow dawn]

so shall I get rid of Time.deltaTime?

[wintry quarry]

yes in both places, but again that's likely only one of your problems.

you probably didn't put the script on the right object or your objects are not arranged properly in the hierarchy etc.

[short hazel]

In the Hierarchy, under the right-click > Create menu

[wintry quarry]

this isn't relevant to our discussion

the sprite editor for the individual sprite is where you'd set the physics shape

[eager spindle]

show us your spaceman

the list of every component your spaceman has

[eager spindle]

and your wall too

[radiant frigate]

my wall is a grid map with a rule tile

i dont know how to exactly show that

[bronze mortar]

Under the right click?

[short hazel]

Yeah when you right-click in the Hierarchy

[radiant frigate]

maybe that?

[wintry quarry]

looks like you're using a rule tile to just spawn a prefab

so you'd have to show that prefab

as that will be a separate GameObject and won't be related to the Tilemap collider really

[bronze mortar]

There's no "create menu"

[radiant frigate]

ohhhhhhhhh

the prefab doesnt have a collider

maybe thats the problem?

[wintry quarry]

maybe, but

Why are you doing it this way

[radiant frigate]

ill just try

[eager spindle]

I mean the tile map collider should cover that but

[short hazel]

I forgot how it's called. "GameObject" maybe? There aren't many options, look through all

[wintry quarry]

instead of using a normal tile

[radiant frigate]

because im a begginer and dont know any other way

this was what made the most sense to me

since it wouldnt let me just choose the square sprite as default i created a gameobject that was just the sprite

[wintry quarry]

I recommend investing in this short tutorial to learn how to use tilemaps https://learn.unity.com/tutorial/introduction-to-tilemaps

[radiant frigate]

i watched it but ill watch it again

maybe i missed out something

[wintry quarry]

Yes the meat of it it seems

create a tile palette

and drawing with your tiles

[short hazel]

UI > Event System
Seems like they pulled all the options up to the root menu itself

And grouped them up better

[bronze mortar]

Do I really need an Event system? Since I'm not using nothing from the UI section

[eager spindle]

I mean just have it in

[short hazel]

Yes, that is what detects objects and dispatches events to scripts

[eager spindle]

It's not that expensive

[wintry quarry]

you are using the event system if you want to use PointerClickHandler

That's part of the event system

[bronze mortar]

aa oki

[short hazel]

You'll need a Physics Raycaster on the camera too

[wintry quarry]

2d*

[bronze mortar]

yippie

it worksss

for whatever reason

PI_happycat

WhatsThis

[eager spindle]

🎊

[rocky canyon]

never a good thing

[radiant frigate]

lmao

mood

[radiant frigate]

i read it and i now created a sprite in my assets which is now with what i draw

and it has collision thanks to the tilemap collider

but i still phase through it

[wintry quarry]

You already had the sprite I thought. This was more a question of using a Tile vs a GameObject

So you owuld have added the tile to a tile palette

[radiant frigate]

yes i added the tile to a tile palette

should i have just placed a bunch of gameobjects as walls?

[wintry quarry]

no

tilemap is better

[radiant frigate]

srry im not understanding what the problem is now

[wintry quarry]

look at the colliders

[radiant frigate]

its in chunk mode

and its well represented i think

the yellow part is the collider

or should be

[wintry quarry]

the green outlines are the collider

it's common to combine that with a Composite Collider2D btw

regardless, this should be alright so - back to the player

Also make sure your camera is head-on. Are you in 2D mode?

[radiant frigate]

yes

[wintry quarry]

can you show your code

[radiant frigate]

sure

what part of the code

the one that adds the force?

[wintry quarry]

ideally the whole script for player movement

https://gdl.space/osibutuhag.cpp

[wintry quarry]

this code isn't really adding forces it's just setting velocity, btw

[radiant frigate]

yes the movement isnt

but the collision should

[rocky canyon]

if ur setting the velocity every frame (b/c of movement) adding forces isn't going to do anything

you'll just reset them the next frame

[wintry quarry]

the collision part isn't going to matter because Update is overwriting the velocity every frame entirely

[rocky canyon]

😄

[radiant frigate]

so i should addforce instead of .velocity?

[wintry quarry]

Not necessarily

i mean basically it has nothing to do with the problem you're talking about

[radiant frigate]

okay i will give some context of why i did things so maybe that helps you help me

at first whenever i collide with the ball it would slow down, so what i made was that whenever i collide with it, it just sends me back

and the way i thought of doing this was with .velocity

but it didnt work, so i tried with addforce and it kinda works, the problem is that i now phase through the walls

[silk fossil]

🤫

[wintry quarry]

neither of those should phase through walls

[radiant frigate]

should i try to change to addForce instead of velocity

[wintry quarry]

it won't make a difference

[radiant frigate]

because since it resets each time for it to impact it has to be very high in the only frame it acts, so maybe by changing it to addforce i can lower it and make it so it doesnt have the speed to phase?

[wintry quarry]

it has to be an issue with your colliders

[rocky canyon]

one workaround is to pause ur player's movement code for the knockback to take affect..

then after a short delay.. reenable it

[radiant frigate]

a couroutine?

[rocky canyon]

    private IEnumerator ResumeMovementAfterKnockback()
    {
        yield return new WaitForSeconds(0.2f); // Adjust as needed
        allowMovement = true;
    }
``` yes a coroutine could probably achieve that

[radiant frigate]

but that would be the same as making my character work with addforce right?

well not completely

but in that aspect

[rocky canyon]

Knockback(){
allowMovement = false;
rb.AddForce(knockbackforce);
StartCoroutine(ResumeMovementAfterKnockback());}```

[rocky canyon]

if u use addforce ur gonna have to add in a little bit more calculation

[wintry quarry]

Again ultimately adding forces and setting velocity will move the object via velocity

so it doesn't matter which one you use

[rocky canyon]

u can't continually addforce or ur player would keep speeding up

[wintry quarry]

it won't change this problem of overlapping

[radiant frigate]

but i´ve checked the colliders and they seem to be working

[wintry quarry]

you should pause the game when it's happening and closely inspect the obejcts and their colliders

[rocky canyon]

try this ^

step thru it frame by frame..

[wintry quarry]

showing your Rigidbody inspector might help too

[radiant frigate]

maybe its collision detection mode?

[wintry quarry]

turn collision detection to Continuous that might help a little

and turn on interpolation (set to interpolate) to make the movement smoother

[radiant frigate]

what does interpolate do?

[wintry quarry]

makes the motion look smoother

it will be naturally stuttery because physics runs at a fixed framerate

[radiant frigate]

ohhh

so i should alwas have it at interpolate ?

[wintry quarry]

Pretty much for any moving Rigidbody

[radiant frigate]

or is there a situation where its detrimental ?

[wintry quarry]

it has a small performance cost but for a single object and especially the player object it's worth it.

[cunning narwhal]

Is there a go-to guide for when I should be using a scriptable object? Technically everything in the entire game can be one right?

[rocky canyon]

Another workaround is if ur knockback affects 1 axis.. that ur movement doesn't for example its common in here to see:

• players being moved with velocity
• jump being added with AddForce

in that circumstance there a work around where u feed the Y velocity into ur movement function.. so the movement function is not affecting the axis that u apply the forces to.. playerRB.velocity = new Vector3(0f, rb.velocity.y, 0f);

just another tidbit of information that might be beneficial to know..

[wintry quarry]

No, everything in the game cannot be a ScriptableObject.

You will need a presentation layer of some kind

Either GameObjects or Entities

[radiant frigate]

okay it was the collision detection mode

[cunning narwhal]

Ah gotcha, I'm confused on when to make one and for what purpose really

[rocky canyon]

they're good at holding data

for example

[wintry quarry]

when you want to create data assets that you can create and edit in the Unity Editor and read in your code

[rocky canyon]

all this data is read-only data.. my player controller just uses it to set up the controller

[hollow dawn]

Everything is ruined and now I have to make a new project 😦

Thanks to you both again, I'm a bit new to SO's and DOTS concepts. So if I understand it right, while I could use a class with my variables to initialize and set values, the SO comes in as a way to save it to a file for later reads?

So I would have a scriptable object that holds player data, map data, items, etc

[rocky canyon]

yea, but u wouldn't necessarily use them to save data to a file that gets read later..

thats more of a job for a JSON type text system

If you need to save ScriptableObject data to a file for later use, you would typically serialize the data to a file using Unity's serialization system (e.g., using BinaryFormatter, JSONUtility, PlayerPrefs, etc.) and then deserialize it when needed..

they're not typically used for persistent data

[rich adder]

eh dont use BinaryFormatter (unsafe)

if you must use BinaryWriter

[rocky canyon]

noted.

i use JSON myself.. just trying to think of all avenues

[cunning narwhal]

Oooh I think I get it now, basically it moves it outside of memory so that other things like prefabs that are instantiated a hundred times can access the values stored in there vs making new memory spots per instance

[rotund quest]

hi
is there a way to spawn an object randomly within a certain range?

for example: i want to spawn object X between these 2 lines, and that no matter what the size of object X is, it will always be between these 2 lines (no clipping)

[rocky canyon]

absolutely.. use min and max values..

and generate a random number between them 2

[rich adder]

yup. use something like Random.Range

[rocky canyon]

u can take the size of the object into account

and just subtract half of it from the min

and half of it from the max

[rotund quest]

wow thanks

[rocky canyon]

well i mean Add half of it to the min and Subtract half of it from the max, but u got the idea

[rotund quest]

yeah

[rocky canyon]

exactly! u can define a reusuable data structure that can be accessed by multiple gameobjects, instances, etc, this can be helpful when u want objects to share the same data without duplicating it in memory..

so stats for a gun in a shooter game for example

[willow scroll]

What was said above, and I also like to use this struct I've created some time ago. Not sure if it helps you.

[rocky canyon]

u should make it an extension to the Random.Range class 😉

Random.Range(min,max,sizeOfObject);

lol

[willow scroll]

Great idea, I will make it in some time when will need to use it again

Haven't used it in a while, found in the old code

[rocky canyon]

i been working my way up to extension methods

starting with my own static classes.. and then once i feel comfortable i'll start using predefined classes to add to

[willow scroll]

Why don't you implement the Up?

[rocky canyon]

lol, havent needed it yet 😉

but i will

im just goofing atm

[willow scroll]

Also you know that ternary operators are cool?

[rocky canyon]

ofc i do!

[willow scroll]

using Input = UnityEngine.Input;

return held ? Input.GetMouseButton(0) : Input.GetMouseButtonDown(0);

[rocky canyon]

imma change it right now 😄

[willow scroll]

Damn, isn't that the same code you've provided some time ago?

Shouldn't you have changed it to the lambda switch?

[rocky canyon]

lol.. when i showed my previous switch statement and said it was ugly?

[rocky canyon]

i did the reverse

ohh yea.. lambda switch

nah, i hadnt tried that yet

ofc, imma tie the two together sometime.. right now its just a public enum called Direction..

[willow scroll]

[this is my response from 2 weeks ago](#💻┃code-beginner message)

[rocky canyon]

but i'd like it to return the direction.. but to do that imma need to pass in the gameobject first

so i can get the correct local transforms

lmao.. eyes still bleeding i guess

[willow scroll]

Now the right one

[rocky canyon]

haha.. i apologize

[willow scroll]

That's alright, I've almost recovered

[rocky canyon]

u found that code too quickly..

i gotta obsfucate my messages a bit better 😄

[willow scroll]

I just searched for my messages containing "left eye"

There weren't a lot

[rocky canyon]

lmao ahh, good memory then 👍

[willow scroll]

It's not, you usually don't forget something that makes your eye bleed fast

[rocky canyon]

like what ChatGPT tried to feed me earlier

c'mon! (╯°□°)╯︵ ┻━┻

when I'm refactoring I always like to get ChatGPT to make me chuckle first

never fails

[willow scroll]

ChatGPT is definitely going to throw a few errors and skip a few parts of the code when refactoring

[rocky canyon]

oh yea, im very aware.. its like coaching a toddler

[willow scroll]

However, this ternary operators will make even ChatGPT chuckle

[queen adder]

Why can't I put any game objects inside of this prefab?

[willow scroll]

Prefabs cannot reference the objects from the scene

[slender nymph]

https://unity.huh.how/references/prefabs-referencing-components

[queen adder]

Oh

[queen adder]

I tried fixing it with this, but it still won't work

[willow scroll]

• 1. Are you sure the objects with the tags TopLeft and BottomRight exist in the current scene?
• 2. Are you sure they're enabled?

[queen adder]

ya, its enabled and tags

[willow scroll]

I mean, you don't expect Start to run on the prefab, do you?

[queen adder]

Wdym

[willow scroll]

If you want the Start method to run, you'll have to make sure the object is in the scene. The Unity methods don't run on the prefabs.

[queen adder]

So here's how it works: I have this game card. When you press the game card, it spawns an Egg, and the Egg prefab hatches a chicken. Up until then, everything works fine. The problem is, the chicken prefab can't contain any game objects inside

Maybe that helps clarify some things because I'm a little confused ngl

[wintry quarry]

you should probably be passing a reference to the spawn area to the chicken when you spawn it

so it can know where to spawn its babies

[queen adder]

It should already work the way it is

[willow scroll]

It's so cute

As PraetorBlue mentioned, simply pass the objects needed for the card when instantiating it

[queen adder]

tysm!!

[queen adder]

What does that mean?

[willow scroll]

When you instantiate the card, assign its variables needed, assuming they differ when spawning different cards

[wintry quarry]

give the chicken script a function like:

public void SetupSpawnArea(Transform tl, Transform br)``` and just call that after you spawn it

[rocky canyon]

instantiatedPrefab = Instantiate(prefab)
instantiatedPrefab.someVariable = 10

[wintry quarry]

More generally it would probably be good if there was a "CardPlatform" script or something

that you generically pass to every card you spawn

and contains all that information

[rocky canyon]

yup, i concur

[queen adder]

Cards? I'm a lil confused, I feel like we're not exactly on the same page 😭

[wintry quarry]

whatever this is

[median rune]

aw how cute .

[wintry quarry]

unit

tamagotchi

[willow scroll]

And you would usually make a struct for the variables required

[wintry quarry]

whatever you want to call it

[queen adder]

chicken? xd

[rocky canyon]

chicken.. same thing

the thing u spawn

[wintry quarry]

when you spawn it, you should pass it a reference to the platform it will live on

[rocky canyon]

how about that.. big blanket term

[queen adder]

aaa

lemme try

[rocky canyon]

noo memes k thx bye

[queen adder]

[rocky canyon]

public class Chicken : MonoBehaviour
{
    public void Initialize(GameObject ground)
    {
        Debug.Log($"Chicken spawned on: {ground.name}");
    }
}

public class ChickenSpawner : MonoBehaviour
{
    public Chicken chickenPrefab;
    public GameObject ground;

    public void SpawnChicken()
    {
        Chicken newChicken = Instantiate(chickenPrefab, transform.position, Quaternion.identity);
        newChicken.Initialize(ground);
    }
}```

[queen adder]

sooo i shouldnt use the "top left bottom right" thingy at all?

[rocky canyon]

what u mean by that?

are you using UI components for all this?

if ur gonna set the position of the chicken/egg/ or whatever.. u can probably just leave it anchored to the center

dont quote me on that tho...

i tend to use 2D Sprite objects.. instead of UI components

which dont have an anchor

[wintry quarry]

well you can but it would be part of the platform script and you can read it from the chicken. Or the platform could have a function where you pass in a prefab reference and it just spawns it for you within the area.

[queen adder]

That's the issue I'm trying to solve. I have two game objects: one at the top left and one at the bottom right.

I also have an egg prefab, but I can't assign these two objects to it to determine the spawn area because prefabs can't take game objects

[wintry quarry]

ALmost every programming problem can be solved by adding layers of abstraction or indirection

[wintry quarry]

because prefabs can't take game objects
This isn't quite accurate. The rule is that assets cannot reference objects in the scene.

They can certainly reference other assets or objects within the same asset

[rocky canyon]

well that problem has already been solved for u..
regardless of ur setup its the same problem.. u cant put scene references in a prefab

[queen adder]

ya xd

[rocky canyon]

u have to do that after the prefab is instantiated

thats true for every prefab.. not just Ui objects

u can use regular values for the bounds..

just find out what the X coord is for the left one.. and the right one

and what Y coord is for the top one and bottom one

[queen adder]

True I guess, you could also do it that way

i guess its the easier way

bump

months and months of dealing with this issue

[slender nymph]

this is a code channel

Why does this hide cursor script not work if I add it as a the player component?

did you click into the game view / is the game view focused??

[frail laurel]

Hello, could anyone help me im trying to figure how to make when Playerisdead the player couldn't move ?

[eternal needle]

[frail laurel]

this is my script https://gdl.space/usunaxipav.cpp

[eternal needle]

Think about which parts of this script you dont want to run if the player is dead. You can just return early to stop any logic from happening further in the function.

[frail laurel]

i don't want him to move

at all

when dead

[main anchor]

does anybody know what causes my player to act like this? (im referring to the slowly sinking on invisible floor and being unable to jump off the ground)

https://hastebin.com/share/veragiduco.csharp

heres my movement script if you wanted to see it

[rocky canyon]

your controller probably is flagged as isGrounded when that starts to happen

its probably how u implement ur gravity

[eternal needle]

Yes I understand the issue, and my answer above is to guide you how you can return early from the functions that do move the player. Also you could just set the rb to kinematic, but then it will also not even fall on the ground

[frail laurel]

how do i return?

[rocky canyon]

return;

[frail laurel]

thank u 🙂

if(!ican'tmove?

or if(!canMove)

[rocky canyon]

! means not

[frail laurel]

thanks

[eternal needle]

! does the opposite for bools, so !canMove means "if I cant move"

[rocky canyon]

!canMove or cantMove would be the same thing

but thats just my example.. u can use a false flag or a positive flag

and name it anything u want

[frail laurel]

so if i am dead but my player can still move

if(!canMove)
{
return;
}

}

}

[main anchor]

its weird though because it differs depending on the height i fall from, example:

[frail laurel]

so i put walk and thoose things in return?

[rocky canyon]

if(dead){return;}

that way, if !dead.. the return wont run.. and the code below it executes.. (the movement code)

[frail laurel]

mhm

[rocky canyon]

ya, because you've built up momentum on the long fall

[grim tulip]

What are the most common questions being asked in beginners code?

[rocky canyon]

the code thats working against u when isGrounded.. isn't going to slow it down as much

[rocky canyon]

why my code not work

[languid spire]

how fix

[grim tulip]

Mmmm okay

[rocky canyon]

its differnt day to day..

[frail laurel]

we learning

every day

[rocky canyon]

a lot of How i reference this

how i make this code do this to this other object..

or why i can't make my prefab do a thing (when they're trying to access the actual prefab and not the instance)

[languid spire]

what does this mean

[rocky canyon]

orrr.. how can i set this thing from this other scene before i even access the other scene

[grim tulip]

Ohhh

Okay

[rocky canyon]

so honest 😄

[slender nymph]

I want that <incredibly googleable thing> to happen. Does anyone have a script I can use

theres a problem here...
if you return early.. its skipping all the code beneath it..

meaning.. if ur bool isDead is true.. theres no possible way for the code thats highlighted to set it back to true

[frail laurel]

how do i fix that?

[rocky canyon]

ohh wait.. that doesn't matter.. because its already true if thats the case

this script doesn't stop playing the audiosource

when the player isdead

[wintry quarry]

Well yeah

    public void SetWalking(bool _state)
    {
        if (isDead) // Check if the player is dead before playing the sound
        {
            return;
        }```

look at what your code does

[frail laurel]

dam

[wintry quarry]

it's not going to reach the part where it stops the audio source

[frail laurel]

it checks

[wintry quarry]

you probably only want to not start the sounds when dead

but still stop it

[frail laurel]

i want like when the player is dead the sound would stop working because now when the player is mowing the realistic sound of walking starts playing

[wintry quarry]

Something like

public void SetWalking(bool _state)
{

    if (_state && !audioSource.isPlaying && !isDead)
    {
        // Play the walk sound
        audioSource.PlayOneShot(walkSound, soundVolume);
    }
    else if (!_state)
    {
        // Stop the walk sound
        audioSource.Stop();
    }
}```

[frail laurel]

now it shows this menu but when i press w i still hear the sound of walking🤔

[wintry quarry]

Or perhaps just

public void SetWalking(bool _state)
{
    if (_state && !audioSource.isPlaying && !isDead)
    {
        // Play the walk sound
        audioSource.PlayOneShot(walkSound, soundVolume);
    }
    else
    {
        // Stop the walk sound
        audioSource.Stop();
    }
}```

but idk if this code is even running at all on the menu something is off

you should probably not even have the movement script enabled anymore when the player dies

[devout oak]

Hi, it's my first time making a post in this server so sorry if something is posted incorrectly. I am making an FPS game as a project but have ran into an issue that I am having trouble fixing. I am making a hover system where upon hovering, the GameObject is outlined (using an Outline script that I got from the Asset Store called QuickOutline) and when F is pressed, the GameObject is also destroyed. I'm trying to hover over a stationary gun GameObject with a raycast and it doesn't detect it.

Couple of things I have already tried:

• assigning a Box Collider to both the GameObject and the model within it,
• assigning the Weapon script to the GameObject,
• tried using ChatGPT to add debugging logs and it said that the raycast detection was working perfectly but it wasn't detecting anything: No Weapon component found on hit object or its parent UnityEngine.Debug:Log (object) InteractionManager:Update () (at Assets/LowPolyFPSLite/Scripts/InteractionManager.cs:72)

https://hastebin.com/share/eyuqagizic.csharp <- InteractionManager
https://hastebin.com/share/kicozatemo.csharp <- Weapon
https://hastebin.com/share/nonusezoti.csharp <- WeaponManager

Apologies if this post is not formatted the best, thank you!

[wintry quarry]

Have you done any debugging?

I see you said you used CGPT to do it but...

You need to print which objecty your raycast his hitting

make sure you're hitting the expected object

note that it will be the actual collider object, so if that's a child of the gun, it's not going to have the other stuff directly for example

Debug.Log and print what you're hitting

[devout oak]

I used ChatGPT because I've never debugged something manually haha, not experienced with that sadly. I'm doing this as part of my uni course. I'll try to debug it and post what the raycast hits.

[swift crag]

well, it's time to get some experience (:

[wintry quarry]

All you do is put print statements where you expect certain things and compare what it prints with your expectations. You're trying to deduce what's going on with the code

Debugging is such an underlooked skill

[devout oak]

The version with debug logs: https://hastebin.com/share/idoyecaquy.csharp

The return is "No weapon detected by raycast.
UnityEngine.Debug:Log (object)
InteractionManager:Update () (at Assets/LowPolyFPSLite/Scripts/InteractionManager.cs:48)"

[wintry quarry]

ok but you should log more info

[devout oak]

Yeah I don't really know how lmao

[wintry quarry]

Just print the name or something

for example

Debug.Log($"The name of the object we hit was {objectHitByRaycast.name}");```

but really... you are being pretty careless with some of this

There's a difference between hit.transform and hit.gameObject and hit.collider

those can be different objects

so.. start printing out what everything is

[devout oak]

I was following a tutorial on YouTube for this because I'm not too experienced with Unity overall. I ran into this issue and just haven't really found any help with it online.

I debugged it the way you're detailing: https://hastebin.com/share/nenirohoqe.csharp

And it says that "Raycast hit: Box_01 (4)
UnityEngine.Debug:Log (object)
InteractionManager:Update () (at Assets/LowPolyFPSLite/Scripts/InteractionManager.cs:33)"

Box_01 is a box asset which the GameObject (the gun) is placed on so it seems like it's ignoring the GameObject completely.

[wintry quarry]

ok so we learned somethign!

Your raycast is hitting the gun itself

[icy sluice]

hello, why AI refuses to pathfind when i build my project, but it does well in editor

[wintry quarry]

that's huge

And easily fixable

[devout oak]

Can you teach me how like I'm five years old lmao, I'm new to Unity sorry

[wintry quarry]

you can just use a layermask on the raycast.
Or perhaps rethink why your gun even has an active collider at this point in time in the first place

[devout oak]

I tried a layermask earlier because that's something that ChatGPT recommended me actually but it's already set to the default layer

[wintry quarry]

Yeah why

You need to use a mask that includes the interactable things but doesn't include other stuff like your gun

For this raycast we only want interactable stuff right?

[devout oak]

Yeah so I want the guns to be detected by the raycast to be hovered so the outline script works when hovered or to be picked up with a certain key

but not other stuff like the boxes

[wintry quarry]

the gun you're holding is certainly not something we want our raycast hitting

so either exclude it via a layermask, or turn its collider off entirely

[devout oak]

It's not being held. It's placed down stationary

[wintry quarry]

because again, why does the gun you're holding need a collider

oh it's not the one you're holding

[devout oak]

The gun isn't being held by the player

[wintry quarry]

ok but like

[devout oak]

It's placed down on a box

that's why the box is detected

[wintry quarry]

Oh it's a totally separate object

[devout oak]

yeah

[wintry quarry]

ok then yeah your gun either doesn't have a collider

or its collider is on a layer that's being ignored by your raycast

or your raycast isn't passing through it

[devout oak]

It definitely does have a collider

[wintry quarry]

ok but what layer is it on

show the full inspector

[devout oak]

I think it might be the raycast not passing through it. It detects the box but not the GameObject itself so I'm 100% certain that the raycast is working but the gun just isn't being detected for some reason

[wintry quarry]

ok and the inspector for the box?

[devout oak]

Wait I just noticed something, it said it hit Box_01 (4) but Box_01 (4) is over here.. the box under the gun is called Box_01 (8)

[wintry quarry]

ok so probably your raycast is just going in the completely wrong place

[devout oak]

Yeah most likely

[wintry quarry]

Looks like you're using Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0));

Where's your main camera located?

[devout oak]

MainCamera's located on the player body

Won't post the image for some reason

One second

[wintry quarry]

You sure that's the main camera?

[wintry quarry]

nope it's not the main camera

[devout oak]

?_? How is it not

[wintry quarry]

the main camera will have the MainCamera tag

[devout oak]

Oh

[wintry quarry]

so you are firing your raycast from some completely different place

[devout oak]

I gave it the tag now

[wintry quarry]

well...

[devout oak]

Let me try again

[wintry quarry]

now you have two

[devout oak]

Oh

Hold on

[wintry quarry]

you should find the other camera that had the tag

[devout oak]

wtf

[wintry quarry]

(there could be more than one)

[devout oak]

all the cameras that came with the asset I installed had the maincamera tag on all the cameras and there were like 5

lmfao that is not something I bothered to check

[wintry quarry]

yep there's your problem

[devout oak]

Let me test it out now

[wintry quarry]

in the future a Debug.DrawRay with your raycast will also have revealed the issue

It would show that the ray is going in the completely wrong place

[devout oak]

Oh my god it works

Amazing

Yeah thank you, I never thought about that

As I said I'm new to Unity, I spent over like two hours stressing about this and couldn't fix it haha

Thank you

[devout oak]

Can you tell me which area of my code I could put this in?

I'd like to try it out before I get off

[wintry quarry]

the spot where you do the raycast of course

[devout oak]

"Ray ray = Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0));"

Here then right

[icy sluice]

hello, why AI refuses to pathfind when i build my project, but it does well in editor

[swift crag]

You should make a development build and see if you're getting errors

A console will appear in the game to display them.

[devout oak]

Nevermind did it, thank you @wintry quarry. I appreciate it tenfold

[icy sluice]

RuntimeNavMeshBuilder: Source mesh Plane.011 does not allow read access. This will work in playmode in the editor but not in player
UnityEngine.AI.NavMeshBuilder:BuildNavMeshData
couple of bilion theese

"GetRemainingDistance" can only be called on an active agent that has been placed on a NavMesh.
UnityEngine.StackTraceUtility:ExtractStackTrace ()
and coupple of bilion theese

[icy sluice]

thannks for help

[swift crag]

So you're building a navmesh at runtime, then?

[icy sluice]

yes

[swift crag]

if you're using the "Render Meshes" mode for NavMeshSurface, you'll need to enable Read/Write on the relevant mesh assets

[icy sluice]

thank you

[slender bridge]

Well its telling you the script, the variable, and where in the code the error is coming from.

[near wadi]

That type of message means you need to specify Which place to use the MinAttribute from (in my limited knowledge)

[frosty hound]

Specifically, you have two namespaces that use MinAttribute and you need to specify which one you're using.

You can first see if you're even using both the ones specified by checking at the top of your script in the using. If it's greyed out, you can just delete it.

hi im fairly new to unity and im recreating watermelon game, does anyone know how to make it so the cloned fruits are deleted when the game over screen pops up?

[timber tide]

Destroy method

or just restart the scene

[dull saffron]

how do i do

destroy(gameObject) for all of them

[wintry quarry]

Put them in a list as you spawn them

Then iterate over the list to destroy them

[dull saffron]

array?

sorry i only use jsabs

java

[wintry quarry]

No a List

Java has lists too BTW

Unless you're talking about ArrayList

C#'s List is the same as Java's ArrayList basically

[dull saffron]

oh ok ill check that out tyy

[final glade]

Guys another quick question sorry, I have different levels (scenes) in my game. I want to set a var differently for each level through serialized field. The problem is it sets it the same for all levels I can’t have different values for it

[wintry quarry]

Where does the field live?

On a script? Which script?

[final glade]

Yes on a script this script is responsible for animation. Basically called GermAnimation

It is attached to a prefab

[wintry quarry]

Ok and you are instantiating it into the scene at runtime?

[final glade]

The var is an int for germ magnitude responsible for the max magnitude of a germ so not during run time

[wintry quarry]

Then you need to either put the prefab directly in the scene at edit time instead and edit the value there, or use another script which you put in the scene and set the field there, and have it communicate with the germ one

[wintry quarry]

If it's not at runtime you can just set it differently in each scene

On the actual instance in the scene

[final glade]

It changes

Like if I set it one it is the same for all the others

[wintry quarry]

Only if you are changing the actual prefab

But the one in the scene can have an override

[rustic dagger]

I need help someone please. I don't know why i'm getting errors for this, but I may just be stupid

[wintry quarry]

First thing's first you need to configure your IDE

When it's configured you will see your errors underlined in red in the code editor itself

!ide

[eternal falcon]

💡 IDE Configuration

[rustic dagger]

thanks!

[wintry quarry]

you will also get autocomplete etc

[crude rampart]

Good evening everyone

I am currently having an issue where I'm trying to split the player and launch it towards the mouse cursor
However the issue is that it doesn't seem to want to go towards the mouse and I can't seem to quite understand
Can anyione tell me if there are any issues with my code?

 void Split()
 {

     if (transform.localScale.x <= originalSize * splitFraction)
     {
         Debug.Log("Player too small to split");
         return;
     }

     // Reduce player's size by a tenth before splitting
     float newSize = transform.localScale.x * (1 - splitFraction);
     transform.localScale = new Vector3(newSize, newSize, 1f);

     // Create the detached part
     GameObject detachedPart = Instantiate(playerPartPrefab, transform.position, transform.rotation);
     float detachedPartSize = newSize * splitFraction;
     detachedPart.transform.localScale = new Vector3(detachedPartSize, detachedPartSize, 1f);

     // Launch the detached part towards the mouse cursor
     Rigidbody2D rb = detachedPart.GetComponent<Rigidbody2D>();
     if (rb != null)
     {
         //find mouse position
         Vector3 mousePos = Input.mousePosition;
         mousePos.z = Camera.main.nearClipPlane;
         Vector3 mousePosition = Camera.main.ScreenToWorldPoint(mousePos);
         //Sending it towards the mouse
         Vector2 launchDirection = (mousePosition - transform.position).normalized;
         rb.velocity = launchDirection * launchDistanceMultiplier * detachedPartSize * launchVelocity;
     }

     // Set the cooldown timer
     cooldownTimer = cooldownDuration;
 }```

[wintry quarry]

what does it do instead?

[crude rampart]

I think its shooting opposite of the mouse actually when I take a closer look

[wintry quarry]

Have you tried using Debug.Log here to print out the various values involved in your velocity calculation and the resulting velocity to see what's going on?

specifically all the stuff here:
rb.velocity = launchDirection * launchDistanceMultiplier * detachedPartSize * launchVelocity;

This seems maybe a little sketchy too: mousePos.z = Camera.main.nearClipPlane; You sure that's right? And is this an orthographic camera, or a perspective camera?

[crude rampart]

Perspective camera I'm pretty sure

yeah its perp

[wintry quarry]

Camera.main.nearClipPlane is almost definitely really small

With a perspective camera it's usually better to use Plane.Raycast instead

[crude rampart]

is there any particular reason?

[wintry quarry]

Yes because it lets you actually get the world position on the desired plane in the world you want

instead of hoping and praying like you do with ScreenToWorldPoint

with ScreenToWorldPoint you need to make sure the z distance is correct, and correlates to the plane in the world you're interested in

See https://unity.huh.how/screentoworldpoint

And see the bottom section about using Plane.Raycast instead which is better IMO

Almost always in these circumstances it makes more sense to specify a plane on which you want to project the mouse, rather than a distance

[zenith python]

How did you make your object face the mouse? I have been trying to do that for a while

[wintry quarry]

2d or 3d?

[zenith python]

3d

[wintry quarry]

You do what we're discussing here to get a world space position

then you do myObject.transform.LookAt(mousePosition);

or you do transform.forward = directionTowardsTheMouse; which you'd calculate based on the mouse world space position

or transform.rotation = Quaternion.LookRotation(direction, desiredUp;

lots of options

[radiant frigate]

im searching how to measure the distance between 2 points, found vector2.distance but i cant manage to make it work, i need to know the distance in a line from point a to b in meters in both x and y dimensions, but every video that i find displays it only in the x dimension

[zenith python]

I just tried that and its rotating in multiple directions as well as not rotating a full 360

[wintry quarry]

Vector2.Distance does it

it's literally the pythagorean theorem btw

[radiant frigate]

yes i know

[polar acorn]

It gets the raw straight line distance between two points

[wintry quarry]

So what's the issue with it?

[radiant frigate]

and that straight line should be 1 single number that would be a float right?

[wintry quarry]

yes

That's what Distance returns

[radiant frigate]

i try to make a comparison with an if and it tells me that i cant do that

[wintry quarry]

show exactly the code you wrote

[radiant frigate]

omw

[wintry quarry]

and the error you got

sounds like you tried to compare a Vector2 with a float or something

[polar acorn]

Yes, that's what it returns

https://docs.unity3d.com/ScriptReference/Vector2.Distance.html

[polar acorn]

What the hell is new Vector2Distance

[wintry quarry]

Why did you write new Vector2Distance?

What is that

distance = Vector2.Distance(a, b);

[radiant frigate]

I WROTE 2D 💀

damn

[wintry quarry]

well you wrotre a lot more than that

you wrote new Vector2Distance

[radiant frigate]

yes

[wintry quarry]

which is just.... nonsense to be frank

[polar acorn]

Which would be a class named Vector2Distance, which you would have had to create

[radiant frigate]

whenever i create a var that is a vector i usually need to create a new vector to which i can later on make the var that i created compare or make equal to

[wintry quarry]

I think you have a fundamental misunderstanding how variables and values and expressions in C# work

remember, first of all, that you're not creating a Vector2 here

you already have two vectors

and you're trying to create a float that is the distance between them

and we have a function that does that

so no need to construct anything with new

[radiant frigate]

yes as soon as i read that i realized that i should change the var to float

im an ape bruh

i even looked at the docs and found nothing but 1 line and got scared

lmao

but it was a whole diff thing

ty guys!

[zenith python]

What do you mean world position

The mouse's x and y?

[wintry quarry]

the position of the mouse after converting the screen space coordinates to world space

[misty coral]

does OnCollisionEnter not get triggered if the rigidbody it is colliding with is kinematic?

I have a wall

[wintry quarry]

OnCollisionEnter needs at least one dynamic body

[misty coral]

huh

so they cant be kinematic?

[wintry quarry]

one can be

but you need one dynamic at least

otherwise there is no collision

[zenith python]

I dont understand how you would convert the two

[wintry quarry]

that was the whole subject of the conversation above #💻┃code-beginner message

[zenith python]

Yeah ive read that like twice now

[wintry quarry]

well I'm not sure how to help much further than that

[zenith python]

What is Plane.Raycast

If i try to put it anywhere it doesnt work

[wintry quarry]

You clearly didn't read this then https://unity.huh.how/screentoworldpoint

[misty coral]

are there any other ways to detect collision with zero rigid bodies

[wintry quarry]

direct physics queries

or write your own math

[misty coral]

😩

[wintry quarry]

is there a reason you need to not use Rigidbodies:?

maybe explain what your goal is

[misty coral]

ok so

I made a monster neck by making a bunch of spheres follow eachother

and the problem is

the neck goes through walls

so I want to use collision detection to make it not go through walls

but adding a rigidbody breaks the way the neck works

[wintry quarry]

well you either need to re-make it with dynamic Rigidbodies or you need to do your own Sphere/Circlecasting as you move the pieces of the neck to make sure they won't go inside stuff

Hence what I said about "direct physics queries"

[misty coral]

The problem with "remaking it" is I cant figure out why rigid bodies break it in the first place

[wintry quarry]

Seems pretty obvious

[misty coral]

Huh?

[wintry quarry]

adding a realistic physics simulation fights with whatever your existing movement logic is

[misty coral]

Ok but I can just choose to disable gravity

even doing so it still has issues

My code is literally just a bunch of distance checks

so if sphere1 is too far from sphere2 it moves back

[wintry quarry]

gravity is only one aspect of the physics simulation

simply disabling gravity doesn't take away from the fact that the physics simulation is fighting your code

your code is attempting to directly control the spheres.
The physics engine does the same thing.

Chaos ensues

you either need to work with it or bypass it.

[wintry quarry]

hence my suggestion here

[flint python]

Hello, in my code, I have .SetActive(false) for the child game object, is there a way to activate back the child object by activating its parent object?

[wintry quarry]

no, you will need to directly activate the child now

[flint python]

ok thanks

[eager spindle]

if this is a problem you're encountering, do you happen to use transform.GetChild?

or anything relating to getting/finding gameobjects

[zenith python]

Thank you, i used the plane and raycast however my object rotates in multiple axis when i only want it to rotate on the y axis

[eager spindle]

using these isn't very healthy

[zenith python]

I cant seem to figure out a solution

[wintry quarry]

that means you used the wrong plane

if you use a plane that is at the height with your object on the y axis, it will only rotate on the y axis

very simple to do that if you just use your object's position to build the plane

[zenith python]

I tried using my objects position but it doesnt work

[wintry quarry]

it works

maybe show your code

and your scene setup

and what you're trying to do

[queen adder]

guys i have spaghetti code 😩

[misty coral]

How does movePosition differe from MoveTowards

[wintry quarry]

MoveTowards is just a math function, it just calculates a position.

Rigidbody.MovePosition is teleportation with RIgidbodies that respects the interpolation settings

[misty coral]

so then the commented out line and the three lines below it are functionally the same right?

(because they are absolutely not working the same in engine)

[wintry quarry]

except for the * 1.15 bit

but also

it depends where this is running

if it's in FixedUpdate yes

if it's in Update then you're doing it wrong

because Rigidbody.MovePosition only can live in FixedUpdate

[misty coral]

Ah

[misty coral]

woops

[wintry quarry]

And a third point - MovePosition doesn't really help you here

it doesn't respect collisions

[misty coral]

Well you said I need to change the way to neck works to use dynamic Rigidbodies

and after that I can worry about collision

[wintry quarry]

I said that was one option

and if you're doing that you'd have to deal with velocities or forces

[radiant frigate]

i remember doing this in my last project but i cant find anything that i manage to understand, how was it that i rotated something in the z axis at the moment of instantiating it ?

[acoustic arch]

can i check if a list contains a specific field on an element?

[wintry quarry]

wdym by containing a specific field on an element?

You mean if any element of the list has a specific value for one of its fields?

[acoustic arch]

so my list contains items that are scriptable objects and it's checking if it contains a specific item/s within it

[wintry quarry]

bool containsItem = myList.Contains(someItem)

[acoustic arch]

this

[wintry quarry]

Either write a loop and check each element, or use Linq.

[zenith python]

Im on mobile, would a picture be fine

[acoustic arch]

alright

[wintry quarry]

would prefer !code

Yes i would do that but the internet on my pc is broken

[dull saffron]

ive got a countdown script, but it starts when the game starts. is there a way to hide it and then have it appear and start at a certain point in the game?

[wintry quarry]

disable it

[dull saffron]

like the hide icon?

the chekc box

[wintry quarry]

no like the enabled checkbox

[dull saffron]

this one?

[wintry quarry]

that's to deactivate the GameObject

you could do that

[dull saffron]

that works yes

[wintry quarry]

or just disable the script itself

[dull saffron]

bbut how do i get it to be called at a certain point

and reaappear

[wintry quarry]

activate it

[dull saffron]

how do you activate it in code

[wintry quarry]

https://docs.unity3d.com/ScriptReference/GameObject.SetActive.html

[dull saffron]

oooo ill take a look

thanks

what does this mean?

[wintry quarry]

You're trying to call SetActive on something other than a GameObject reference

[dull saffron]

ohhh rn im calling it on the script

[wintry quarry]

well that doesn't make any sense

SetActive is a thing on GameObject

[dull saffron]

does it work on a textmp?

[wintry quarry]

GameObject

Only GameObject

[dull saffron]

ohh ok got it

[wintry quarry]

all of these things are components that are attached to GameObjects

[dull saffron]

so if i simply put a tmp on a gameobject

i can use set active?

[wintry quarry]

THere's no way to have a TMP that is not attached to a GameObject

so I don't really understand the question

[dull saffron]

i want to make the countdowntext appear

[wintry quarry]

those are GameObjects

[dull saffron]

at a certain point

[wintry quarry]

Everything you see in the Hierarchy is a GameObject

[dull saffron]

but its a text

the countDownText is like a tmp

text

[wintry quarry]

TMP_Text is a COMPONENT

do you understand the difference between Components and GameObjects?

[wintry quarry]

everything in the hierarchy is a GameObject.

GameObjects have components attached to them

When you select a GameObjectyou can see all its Components in the inspector.

these are components^
