hi can anyone help with this im trying to be able jump only when i hit the ground but sometimes, when i still touch the ground isGrounded gets set back to false which is the issue, but i dont know why.

[visual linden]

Try being a bit more generous with the && rb.linearVelocity.y <= 0) check. Eg rb.linearVelocity.y < 0.01f because it can sometimes get stuck hovering around really small values due to how the physics work.
I'd also put some breakpoints or debug logs in the different methods to try to get more clarity into why exactly it's either incorrectly setting isGrounded to false or not correctly setting it to true.
edit I actually don't know why you're checking the velocity at all 🤔 If you enter the ground trigger - surely you are grounded, no?

[glossy eagle]

Hi. One question, if I have a method that is something like

public GenericMethod<T>(T param)
{
  Debug.Log(typeof(T);
}

and I want to have an array of different values for T, how would I do that? What would that array "type" be? Like let's say I have a for loop that loops through an array with different values for T, and I want to use that different value of T for every loop. Something like this:

for (int i = 0; i < PossibleSnapshotInfoTypesArray.Length; i++)
{
  GenericMethod<PossibleSnapshotInfoTypesArray[i]>();
}

In this case, how would I make the PossibleSnapshotInfoTypesArray variable if that's possible?

[languid spire]

use object[]

[glossy eagle]

and then to create the array what do I have to enter there? Something like this?

var PossibleSnapshotInfoTypesArray = new (string, object)[]
        {
            ("pos", PhysicsSnapshotInfo)
        };

("PhysicsSnapshotInfo" is the name of a class)

[languid spire]

so thats a Tuple array and you would add to it using
("pos", new PhysicsSnapshotInfo())

[glossy eagle]

ahhhh okay

thanks

and then I thought I could just do

GenericMethod<PossibleSnapshotInfoTypesArray[i].Item2>(); 

but that gives an error. Any idea why please?

[languid spire]

yes, you cannot use a variable in place of a generic type

[glossy eagle]

ah

then I don't know how to fix it😅

[languid spire]

you do not need the generic if you do

public GenericMethod(object param)
{
  Debug.Log(param.GetType());
}

[glossy eagle]

like basically what I want to make is be able to use JSON deserealize with different types, so I have the method that I cannot change that is

JsonConvert.DeserializeObject<T>()

[languid spire]

Pretty sure JsonConvert has an overide that takes a Type instead of the generic

[glossy eagle]

ohhh okay I see it. Thank you so much 😄

[languid spire]

you might also like to consider for this

var PossibleSnapshotInfoTypesArray = new (string, Type)[]
        {
            ("pos", typeof(PhysicsSnapshotInfo))
        };

[glossy eagle]

yeah I changed that

[severe onyx]

I'm wondering about the best way to store data in a way that other scripts can globally access it. like for enemies. if I want a spawner to spawn a random selection, what would be the recommended way to expose that data to the spawner? The main approach I can think of is make each of them into a prefab, give the spawn script a public list and drag in all prefabs manually, but that doesnt feel like the right answer

I guess a similar question applies to a list of classes that share a parent; if I want some other script to randomly pick a weapon Id like it to have access to all scripts that inherit from the weapon script without turning each one into a prefab

[cosmic dagger]

place the enemies in a list when they spawn. that way, you have access to all of the enemies . . .

[hexed terrace]

Use Scriptable Objects to hold data, then you only have 1 prefab and swap the data

[real tinsel]

hey everyone, im not sure if this is the right channel but does anyone know why I can't edit my script in jet brains rider? instead of the normal cursor ive got this block on my text and can't edit anything? cheers

[burnt vapor]

Press your Insert key

[real tinsel]

yeah I thought of that aswell, doesn't work, just takes my cursor all the way to the left

[cosmic dagger]

SOs can hold data during runtime. use an SO asset (that holds a list) as a variable on the spawner. the spawner can access the SO variable to gain access to the list of enemies . . .

[burnt vapor]

Oh, that's usually the reason. Idk then

[severe onyx]

will look into it, ty

[hexed terrace]

that's not the insert key then

[verbal dome]

Sounds like home key behaviour

[hexed terrace]

VS has an indicator in the UI to show that you've got the insert mode enabled, you can press this to toggle.. does Rider have similar? Look around the UI

[real tinsel]

oml my num lock was toggled 😂

thank you

been struggling for like half an hour 😭

[cosmic dagger]

the insert key doesn't move the cursor all the way to the left. did you press the right one?

[real tinsel]

nah I got it now cheers

[severe onyx]

I get the idea in concept but I'm a little confused about the actual implementation here. The way I understood SOs to be used so far would imply I:

1. create a scriptableobject-script that has nothing but a list
2. create an instance of the SO in the asset folder
3. fill the list of that instance with... what exactly if not prefabs?
4. create a variable for the scriptableobject-script from step 1 in some other script I wanna access the list in and then drag the instance I created in 2 in as a reference

so I dont really understand how that solves the problem Im having at all, I feel like Im missing something basic here

[cosmic dagger]

nice, the first two steps are rock solid. for the third step, the list is filled during runtime. as the enemy is spawned, it adds itself to the list . . .

so the enemy script will have a reference to the SO asset as well . . .

[severe onyx]

no no. I dont need a list of spawned enemies. I need a list of all enemy types that exist to pick from for spawning

[cosmic dagger]

that is one option. the other is the spawner itself will add the enemy to the list after spawning, so the enemy doesn't need a reference to the SO asset . . .

[cosmic dagger]

oh, didn't get that from the original question. so you want to spawn a random selection of different enemy types, not just enemies . . .

[verbal dome]

Do you need to automatically generate a list of the child types deriving from weapon?

[severe onyx]

the spawner needs to be aware of each different enemy that I created outside of the running game, in the editor. I wanna know if there's a better way to let it know which exist other than turning them all into a prefab and dragging all prefabs into a list yknow

[verbal dome]

If you dont turn them into prefabs, what would they be?

Gameobjects in the scene?

[cosmic dagger]

that would just be a list of prefabs then. much simpler . . .

[severe onyx]

ok fair enough

[verbal dome]

and dragging all prefabs into a list yknow
This part you can automate with some editor scripting if you want

Like storing them all in list on a SO asset automatically

[severe onyx]

the list itself could be an SO I suppose if I want it to be easily accessible and modified across different scripts without them all talking to each other though?

[verbal dome]

Yeah, you can use SO as a "database"

[severe onyx]

that definitely seems useful, ty

[cosmic dagger]

true, you can automate that if you want. e.g., a button or a method you can call from the editor to find and populate the list with prefabs that derive from a class . . .

[severe onyx]

database is exactly the use case I was looking for I guess

[cosmic dagger]

exactly. SOs are great as databases for storing groups of objects, not just prefabs, but actual C# classes as well . . .

[severe onyx]

so if I add an enemy I just add it to the SO asset instead of changing values on the spawner gameobject directly yknow

[cosmic dagger]

they work well because you can use the SOs across scenes without a need to reference . . .

[severe onyx]

yeah thats a huge boon

Im thinking if I got, like, 20 different swords that use the same logic but with different values then I turn the sword class into a SO and create 20 different assets of it where I fill in the values, aye?

like. creating a new class that inherits from sword for every single one seems insane. but if the logic is the same I realise I could just create a prefab for each one and adjust the values there. and Im wondering if SOs arent the more elegant solution here as well?

[cosmic dagger]

yes, this works so long as the values don't change. SOs work best with immutable data. if the values on the sword change/update during runtime, then you have two options:

• use prefabs instead and instantiate it. mutating data only affects that copy
• store the values in an SO as data, then copy that data to a script (on a GameObject) that will mutate it . . .

[severe onyx]

interesting. I was thinking more of having modifiers in the parent object that I change at runtime. eg get a buff that doubles your atk-speed -> set the modifier for atk-speed in the instance of the sword-class without touching the base atk-speed data it pulled from the SO

[cosmic dagger]

you'll find that using composition over inheritance works better with Unity. you want to avoid creating large inheritance chains. they'll drag you down . . .

[severe onyx]

yeah wanting to avoid them is precisely why Im asking these questions

[cosmic dagger]

yes, this method works best . . .

[severe onyx]

so how do I got about turning them into actual objects at runtime? create one universal prefab with another script attached to it that exists purely to handle actual object instances of sword and fill it with data pulled from the SO?

I guess I was imagining a solution where I can attach something equivalent to an SO directly to a gameobject

or am I just back to using prefabs at that point

[swift crag]

Bingo

You can store the immutable characteristics of an item in an asset, then store:

• a reference to the asset
• a list of modifications

on your runtime item object (which could just be a plain class, rather than being a MonoBehaviour that you have to attach to a game object!)

[severe onyx]

ultimately I still need a gameobject to communicate all that data to though if I want a visual representation

[swift crag]

Right, you'll have a game object with renderers and other components to display the item

[severe onyx]

so that trips me up rn, if there's an efficient solution for that without just turning them all into prefabs anyways

[swift crag]

I was poking at a soulslike game a while ago. I had item definition assets that stored things like the name and the item's stats

The asset also referenced a prefab, which was the actual physical object you'd see in-game

It was possible for multiple items to use the same prefab (think about 30 kinds of potion that all use the same model, just with different colors)

The item definition was referenced by the actual Item class, which represented a single instance of that item. Modifications to the item were stored on this class.

[severe onyx]

right. so in my case we'd have the sword SO, 20 different SO assets, and the sworditem monobehaviour attached to one universal prefab, yeah? modify the prefab instance at runtime with data read from the SO asset I wanna use at the time and I got what Im looking for basically?

[swift crag]

in short:

• Item: A thing in your inventory
• ItemDefinition: A blueprint for an item
• ItemProp: A physical object that shows up in the game when you use an item

Item points at ItemDefinition and ItemDefinition points at ItemProp

[cosmic dagger]

as Fen mentioned, this is right. i found it easiest to create an SO that holds a C# class variable with all the data. your prefab GameObject would have a MB class with a corresponding C# class variable to copy the data to. this is easier than having individual variables on a SO that you have to copy over . . .

[severe onyx]

ooooh

[swift crag]

That's also a decent idea -- you might realize that:

• Things that you can change when designing an item
• Things that the player can change in-game

overlap pretty well

In that case, you could copy the stats from the item template into the item instance

This would cause incorrect stats if you changed the template later on, though

That's why I'd rather keep modifications non-destructive -- you just store a list of changes

[severe onyx]

yeah I was wondering how to get around doing the latter if I need a corresponding MB for the SO class anyways

[swift crag]

Item is a serializable class, but it's not a Unity object
ItemDefinition is a ScriptableObject
ItemProp is a MonoBehaviour attached to a prefab

in the game, I had separate classes for melee weapons, ranged weapons, and consumables. this made me vaguely unhappy

[severe onyx]

I thought I had understood it but now Im unsure again lol

[swift crag]

it might be helpful to rename Item to ItemInstance

[severe onyx]

the "c# class variable" in question here cannot be the ScriptableObject class itself or?

[swift crag]

a field holding a type that isn't a Unity object

you might see this referred to as a "POCO" -- plain old class object

[cosmic dagger]

that would be the field holding the actual item. using Fen's example, it'd be the Item class . . .

[swift crag]

[System.Serializable]
public class ItemInstance {
  public ItemDefinition definition;
  public string nickname;
}

Note that in my example, you are not copying anything from ItemDefinition when you want to put an item in the user's inventory.

You're just creating an ItemInstance and pointing it at an item definition

[severe onyx]

ItemProp here for example would have an instance of a class that holds all the numbers the ItemProp uses for it's logic, like animating and actually dealing damage, and THEN I create an SO that basically just holds that same class?

[swift crag]

ItemProp is the physical object -- a literal "prop"!

gah, name collisions

that sounds like "item property"

[severe onyx]

no no

I get what you mean by that

it's a monobehaviour and it's attached to a gameobject

this is hurting my brain lol. I may just be bad at abstract thinking

[swift crag]

item and inventory systems are fun

I misunderstood you as misunderstanding me :p

[severe onyx]

ok let's try this again

[swift crag]

Here's an example from that game.

• InventoryMeleeWeapon -- equivalent of ItemInstance
• WeaponSpec -- equivalent of ItemDefinition
• Weapon -- equivalent of ItemProp

please ignore the horrendous exception throwing in the first file 😬

[tulip nimbus]

Debug.DrawLine(transform.position, Vector3.down, Color.red);

How can i make it that the Raycast (Or in this case, Line) goes down from the players position?

[swift crag]

DrawLine draws a line between two points

use DrawRay if you want to draw a line from a point in a direction

[tulip nimbus]

So Vector3.down should work when doing Physics.Raycast?

[swift crag]

if you pass it as the direction for the raycast, yes

[visual linden]

transform.down times some length* instead of Vector3.down, DrawLine takes two points, from and to

[swift crag]

note that Raycast doesn't care about how long the vector is

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Physics.Raycast.html

See the documentation for the method

[tulip nimbus]

Thank you!

[swift crag]

It uses a separate maxDistance argument

[visual linden]

transform.position + Vector3.down * length

[swift crag]

So make sure that, if you use DrawRay, you multiply your normalized direction by the max distance you provide to the Raycast method

transform.down is good if you care about the player's own "down" direction, rather than the world -Y direction

this is relevant if the player rotates

[visual linden]

Yeah I was getting ahead of myself

[tulip nimbus]

Ah i see

[tulip nimbus]

Still very helpful imput, i appreciate it

[stark flame]

I’ve got a problem , I have a game where a ball is getting generated and I want to put on a random spawn interval with Random.Range(3f, 6f); in the invokeRepeating method but I don’t actually know where I should store that random variable

[swift crag]

Should the spawn time get randomized every time the ball spawns?

If so, something like this doesn't work

[stark flame]

Yes

[swift crag]

InvokeRepeating(nameof(SpawnMethod), Random.Range(3f, 6f));

[severe onyx]

ItemProp is a MB on a gameobject and it executes the logic that happens when I press buttons and has a variable of Item
Item is a non MB class that holds all the variables ItemProp uses for that logic
ItemDefinition is an SO that basically just holds Item, assets made from it just change the numbers within Item for different versions of the item
at runtime, I access a list of all the ItemDefinition assets and pull its version of Item to set the field of Itemwithin ItemProp so it knows which values to use?

[swift crag]

This picks one random number and you're stuck with it forever

Consider having the spawn method invoke itself at the end, or using a coroutine so that you can do this

while(true) {
  Spawn();
  yield return new WaitForSeconds(Random.Range(3f, 6f));
}

[cosmic dagger]

you need to call your own method that uses a random time. consider a coroutine . . .

[stark flame]

That’s what I did but it still has an issue where it says it has to be called in Awake or Start

[swift crag]

Show the actual error

I'm guessing you're trying to do this

private float random = Random.Range(3f, 6f);

[swift crag]

I would make one change here:

You don't store an Item in an ItemDefinition. The Item refers to an ItemDefinition. It uses that definition to calculate stats to give to the ItemProp.

[stark flame]

UnityException: RandomRangeInt is not allowed to be called from a MonoBehaviour constructor( or instance field initializer), call it in Awake or Start instead , called from MonoBehaviour ‘SpawnManagerX’

[swift crag]

In my case, though, I just hand the WeaponSpec (the definition) directly to the Weapon (the prop).

[stark flame]

I haven’t learnt yet how a coroutine method works , I’m actually new to unity

[swift crag]

You aren't allowed to call quite a few Unity methods when initializing a field

This also wouldn't be very useful, since you'd just have one random number forever..

[severe onyx]

having the SO hold just the serializable class was how I understood what this message was recommending I do

[swift crag]

That's what UnityInvader suggested, yeah

[stark flame]

That’s what I did but it just spawns the ball once

[swift crag]

Show your code, please

because otherwise Ill list all the same variables in Item and ItemDefinition and copy them over in code basically, yeah?

[sonic plover]

yo

[severe onyx]

like obviously it would work either way, Im just wondering what's prettier

[swift crag]

I would prefer to calculate the values as needed. I wouldn't copy ItemDefinition.damage into Item.damage

I'd give Item a property that calculates the damage based on the definition's stats and any customizations we've made

public ItemDefinition definition;
public float extraDamage;

public float Damage => definition.damage + extraDamage;

very loosely

[severe onyx]

oh okay. I kinda thought that was going into ItemProp I guess

[swift crag]

There is a lot of wiggle room here

I would want the ItemProp to just ask its Item "hey, how hard do I hit?"

and then the Item asks the ItemDefinition "how hard does this thing normally hit?"

then it sprinkles on any modifiers and hands the result to the prop

because ItemProp has like

and stuff like that right?

massively simplified lol

[swift crag]

Yeah..

In my code, I have a whole "Hitbox" and "Hurtbox" system to handle the actual detection

[severe onyx]

ok gotcha

[swift crag]

a Hitbox notices an overlap and tells the Weapon about it

(see the Contact method)

[severe onyx]

yeah the hit detection stuff is a can of worms Ill open another day

[swift crag]

there are also Blockboxes to handle blocking and parrying

well, I wound up pivoting to bloodborne style parrying, so that became irrelevant

garme design

[severe onyx]

generally, it's not efficient to do collision.collider.getcomponent<whateverhandlestakingdamage> though right?

You must wrap your message in three backticks

I’ve not got those ‘ on my keyboard

[swift crag]

```

[cosmic dagger]

no, use one of the paste sites to post your code . . .

[swift crag]

ah, hm, that's a problem

use https://paste.ofcode.org

[swift crag]

    void OnTriggerEnter(Collider other)
    {
        if (other.TryGetComponent<Blockbox>(out var blockbox))
        {
            weapon.Contact(this, blockbox);
        }
        if (other.TryGetComponent<Hurtbox>(out var hurtbox))
        {

                weapon.Contact(this, hurtbox);
        }
    }

TryGetComponent is marginally better because it doesn't allocate a bogus object if it can't find anything

the result will be a genuine null

instead of an invalid unity object

[runic lance]

it only allocates in the editor though

[swift crag]

yeah, that's true

the main advantage is that it makes your intentions more obvious

if I can find X, then ...

[cosmic quail]

really? how does it avoid allocation otherwise?

[ancient hamlet]

I have a question about implementation: what is the main idea behind hero based games (like MOBAs, AutoBattlers, etc...) that have specific skills for each hero? Do I try to break down the skills into their components of what they do and inherit them or do I create a single class for each skill ?

[swift crag]

then log in to discord on your computer.

[swift crag]

This is a pretty tricky problem

[fickle plume]

How are you debugging your code then?

[swift crag]

You can try to break skills down into composable pieces

[stark flame]

Sent it from my computer to my phone

[swift crag]

but you'll probably wind up with so many complex interactions and edge cases that it's not worth doing

[stark flame]

Because I’ve not got discord on my pc

[swift crag]

Discord has a web client. Use it.

[fickle plume]

It works in a browser.

[cosmic dagger]

discord was originally a website before an app. it's always been there . . .

[ancient hamlet]

I guess I could break the easy stuff down... like an interface to buff a specific stat, or leap to a specific position...

[cosmic dagger]

oof, that's a big topic. i'd separate the skills into effects, data, and physical instances (prefabs) that run logic based on the data (probably an SO) . . .

[ancient hamlet]

wow I'm probably on the right track... im desiging skills in a spreadsheet then looking forward to convert the spreadsheet into scriptable objects...

[stark flame]

Once I’ve pasted it , should I copy it ?

And send yall

[fickle plume]

@stark flame Stop talking about it and just do what you were asked.

@stark flame Why would you paste the same thing again?...

[stark flame]

ive pasted it from the site youve given me

and then copied it as idk what to do next

[fickle plume]

The site creates a link, you paste that link

[cosmic dagger]

you post the link from the website. we click on the link to view your code . . .

[cosmic quail]

what would be the issue with a single class for each skill? sounds like the best way to do it

[ancient hamlet]

i currently have 66 units

[runic lance]

https://discussions.unity.com/t/getcomponent-does-not-allocate/925907
this is the newest discussion I could find about it
it allocates in the editor for better debug purposes, in builds it'll probably just return a default null object

[ancient hamlet]

each with a unique skill

[stark flame]

https://paste.ofcode.org/iyitTkskhG4AgJ4iZwFdF8

[cosmic quail]

if they're truly unique then you would need different code for each, no?

[ancient hamlet]

they are a mix and match of different things. I'd be rewritting a lot of code.. like 50% of them give a shield or heal

[cosmic dagger]

bloat and limitation (no scalability). 100 classes for different skills creates bloat and a lot of repetitive code. breaking skills into separate parts allow you to mix/re-use logic and effects . . .

[fickle plume]

You should add your question as well.

[cosmic quail]

oh true, yeah in that case a separate script for each would be bad yeah

[stark flame]

... , I'd like to store the randomization into a variable and then fill the variable's name into the invokeRepeating(),but I don't really know where to put , i already tried in the SpawnRandomBall() and it doesnt work

[cosmic quail]

woah that's insane

i never knew that

[stark flame]

at the moment;as it's imediately stored in the invokeRepeating() and i'd like the random number between 3 and 6 to be changed everytime

such as if it was in an Update() method

[fickle plume]

Did you read what that method actually does? https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.InvokeRepeating.html

[pseudo dirge]

Hi guys, can you tell me how can I spawn a prefab at a point I want on the x and y axis, but without creating separate gamobjects for it? I tried to use an array where I put the points I need and added them to the vector, but the prefab spawns on the center of the vector

[fickle plume]

You've set time range once. Then constantly running it over that same period.

[stark flame]

yes it's invoking a method that starts at a specific time at a certain time

each time

[fickle plume]

From the range it can execute every 0 seconds i.e. every frame

What do you actually want to do?

[stark flame]

I want the time range to be random everytime the ball falls and not to have a random time range which is all the time the same

[fickle plume]

Why are you posting this in a code channel?

[ancient hamlet]

sorry I thought it involved code at some point, plus beginner question

I moved it

[pine bone]

Hello, i'm creating enemies for my 2d platformer game and i want to ask whats the best way to code unique enemy mechanics? Should i create a base enemy class and inherit from there? Whats the eaisest way that i can add various enemy types without having to rewrite a lot of the code

[ancient hamlet]

you can create an base enemy controller and inherit it for each new enemy type, or create multiple interfaces for each component and use them to enemies with mixed and matched functionalities

[fickle plume]

Again, You are setting a timer on a repeating method to be always executed at that period, once. Think where it should be to work more than one frame.

Also you should use Coroutine for repeated actions to have more control.

[pine bone]

how can i use interfaces for this?

[stark flame]

i maybe should put in the SpawnRandomBall() method

i already tried putting this variable outside any functions and it does the same its actually doing rn

[stark flame]

the thing is;im new to unity so i was following the junior programmer pathway and ive not learnt yet coroutine functions

[fickle plume]

You are moving your transform position to that point, which you don't need to do. Just offset coordinates where you instantiate things.
(You may want to position your transform at the start of coordinate system. Then Row * cell size = position. )
In your case you've hardcoded positions already in arrays but not using them for position.

[stark flame]

anyway thanks @fickle plume ;ill figure out how to do it by myself

[fickle plume]

Since you are already doing things outside of the lesson, might as well learn how coroutines work. Also debug whatever you are doing to understand how and when it works. http://unity.huh.how/debugging

[ancient hamlet]

something like this

public interface IUnit
{
    string Name { get; }
    int Health { get; set; }
    int Attack { get; }
    int Defense { get; }
    void TakeDamage(int damage);
    void Move(Vector3 targetPosition);
}

then you just

public abstract class UnitBase : IUnit
{
  ...
}

now you have a base class for every new enemy so you dont need to start from scratch~

[stark flame]

yea thanks,ill look at it

[ancient hamlet]

you probably want to save a reference to the gameObject from return of that Instantiate()

[polar acorn]

The second parameter of instantiate is the position.

Give it the position you actually want

[deft ridge]

Hi! I'm making a fighting game project in Unity and I've coded in the movement and reading inputs. Now I want to start adding visuals like the background and actual character sprites. I'm having an issue where I added a background but it still shows the white space behind it. If I increase the size of the image it'll become blurry which I want to prevent. I'm not sure if the problem if the problem is the size of the background image or the size of the other objects and camera in the scene. How can I fix this? Here's the camera script i made as well in case that contributes in any way: https://pastecode.io/s/zuy4tq0v

[pine bone]

thanks, i will look into this

[stark flame]

Omg , thanks a lot bro

[fickle plume]

@visual linden don't post LLM generated answeres on the server.

Read #📖┃code-of-conduct

[visual linden]

That was not LLM generated, I sat here typing it up myself

[fickle plume]

Next time I will ban you then

[stark flame]

Can you send it in dms please ?(really sorry for disturbing you )

@fickle plume can’t you get back the code in logs please

I had no time to check it

[fickle plume]

@stark flame You can lookup coroutines example in the manual

[visual linden]

I don't even know what to say, this is hilarious.

[ancient hamlet]

can I script my way into generating game data as scriptable objects files from a serializable filetype (json, speadsheet) or is that a janky solution?

im setting each single value by hand in the editor, it gets job done but takes some time

[fickle plume]

That is the purpose of Scriptable Objects. You can preset them, offload to json, modify and load data runtime.

[rough lynx]

Uhhh what??

Sorry it just seems like a bit of an unenforacble rule maybe I shouldn't start something here

[fickle plume]

@rough lynx You do know what is a #📖┃code-of-conduct ? Also don't spam the channel with off-topic.

[rough lynx]

I read the community conduct to see if it was a rule and it was so fair play but it's not like there's really a way to enforce it considering there's no way to prove a message is AI generated unless told so

[polar acorn]

It's not hard to tell an AI message from a human written one

[rough lynx]

Well this person is claiming their message was flagged as LLM generated after it got deleted so it could be

[rough lynx]

Why hatebin and gdl.space? Where they any different to something like hastebin?

And why not just pastebin?

[burnt vapor]

I liked how straight to the point they were

Nothing but a straight up paste with proper highlighting

[polar acorn]

Have you used pastebin

[rough lynx]

Yeah I mean it's not exactly drag and drop since you have to select the syntax highlighting but it's cool aside from that

[polar acorn]

No syntax highlighting, 80% of the page is ads, it has a fucking algorithm. Suggestions for dumps of text! Such a bloated garbage website

[rough lynx]

Dang I didn't see the ads bit since I'm an adblock user

And I don't think I've had suggestions but I dunno if that's my browser blocking "creepy stuff" as it calls it

[polar acorn]

Trying to read a pastebin in mobile is like playing Where's Waldo with code

[rough lynx]

Oh god yeah I just turned off the blocker and I've got 4 ads and one that scrolls with me at the bottom

[pseudo dirge]

Friends, why can't I link to the second script when connecting it as a component? Unity doesn't even see it.

[polar acorn]

Do you have an object with that component on it in the scene?

[pseudo dirge]

The one I'm trying to add?

[polar acorn]

So you're trying to add a reference to itself?

[pseudo dirge]

Now I'm working on the logic that when you press the button potions fall out of the bucket, I need them to fall out according to the cells that I set in another script.
The other script has an array of these cells and adds the bucket itself at startup.

[polar acorn]

So, what object has the SpawnTools script on it that you want to set the tools variable to

[pseudo dirge]

It's on the spawn manager, it's an empty object. But when the game starts, it creates a prefab based on the given points.

[polar acorn]

Prefabs cannot reference in-scene components. You will need to set that variable after spawning the prefab

[pseudo dirge]

Spawn Item is on the prefab, which is created at game startup. It is from this prefab that I am trying to call the Spawn Tool

[shadow rain]

how do i disable a script from another script?

bc ive got this

more enable the script ig

[pseudo dirge]

Would it be better to separate the cage script, from the prefab creation? Do I understand correctly that if the tool will be inherited from the array with cells, then the tool can become a parent for potions and then when I click on the tool I will be able to distribute potions to the cells? Sorry for stupid questions, I'm just learning to program and I'm not very familiar with oop principles.

[polar acorn]

So, is SpawnTool on the same prefab you're trying to reference it, or is it in the scene?

[polar acorn]

If you want it to not be enabled, try setting enabled to not true

[shadow rain]

no i wawnt it to be enabled mb

i shouldve said

thats the error as well

[polar acorn]

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

[pseudo dirge]

He is on the stage. He also creates tools, and from the created tools I'm trying to get the coordinates of the cells for spawning potions

[polar acorn]

Okay, so like I thought. Prefabs cannot reference objects in the scene. You will need to set that variable after spawning an instance of the prefab

[tropic sundial]

Just wanted to check- what is the approved method of verifying whether any future code posted here is llm generated or not? Want to make sure I'm solid before possibly helping anyone.

[polar acorn]

Internal error in the editor. Close any graph windows you have (like animator, shader graph, etc.) and clear the console. It should go away. It won't be included in any builds

[fickle plume]

There isn't one. I had reasonable suspicion they have. They barely posted a few lines of code in the past and then produced example full customized solution with comments on each line of code.
And also their reaction afterwards.

Also in general posting entire solutions is not great for learning as well.

[swift crag]

it sounds like you're asking about telling if someone's asking about their gpu-barf code

[tropic sundial]

Was the code not directly helping the person being replied to? You said there was helpful comments for each line?

[swift crag]

it's usually very obvious, because the code is stuffed with unnecessary comments

i don't actively search for it or anything

Hi reddit

[languid spire]

The problem is, there was no guarantee that the code even functioned never mind do what was required. This is often the case with AI code

[queen adder]

Can someone help me with a Unity 2D script?

[frosty hound]

🫴 #💻┃unity-talk message

[polar acorn]

There was more to Osteel's message than "just post it in the other channel"

[queen adder]

what?

[polar acorn]

you have to actually ask a question

[cosmic quail]

you didnt do what he asked

[frosty hound]

Let me break down my sentence for you in a way that might be easier to understand:

1. You have to explain your issue. This means you have to explain your issue.
2. You have to show your code. This means showing your code

And then do so in this channel, which is for beginners and code.

[queen adder]

then can i post here?

public class TeleportObject : MonoBehaviour
{
    public DoorTrigger doorTrigger;  // Referência ao script DoorTrigger

    public GameObject objectToTeleport;  // O GameObject a ser teleportado (Player ou outro)
    public Transform teleportPoint;  // O ponto para onde o GameObject será teleportado

    private void Update()
    {
        // Verifica se a variável DoorOpen é verdadeira no script DoorTrigger
        if (doorTrigger != null && doorTrigger.DoorOpen)
        {
            // Teleporta o GameObject para a posição do TeleportPoint
            objectToTeleport.transform.position = teleportPoint.position;

            // Reseta a variável DoorOpen para impedir que o teleporte aconteça repetidamente
            // Isso garante que a porta só será aberta uma vez
            doorTrigger.DoorOpen = false;  // Mantém a funcionalidade do DoorTrigger
        }
    }
}

[cosmic quail]

you forgot to say what your issue is tho

[swift crag]

give them a moment :p

[frosty hound]

NRE on objectToTeleport is my guess

[queen adder]

my problem is: this script destroy the effect of other script

[frosty hound]

This script has no code that suggests it's destroying anything. What effect, what script?

The DoorTrigger object? Is there an effect playing that only happens when DoorOpen = true?

[swift crag]

they probably mean that another component stops working correctly

"destroy the effect"

[queen adder]

DoorTrigger is the script

and the effect of him is Teleport Player to X, Y, Z

[frosty hound]

Well, your code will only teleport the object once, because it sets doorTrigger.DoorOpen = false after it does, which fails the condition in the if statement since that looks for it to be true.

[queen adder]

ammm

ill try fix this

[frosty hound]

Assuming that's the issue, you need to, at some point, open the door again on your doorTrigger

[livid sable]

Hello, can anyone help?

[short hazel]

[livid sable]

oh sorry

[cosmic quail]

no question? 🤔

[shadow moon]

how is Quaternion.LookRotation supposed to work in 2d without my sprites turning into 1d lines then breaking lmao

[verbal dome]

It has a second parameter that it uses as the "up" vector

[shadow moon]

yes

[verbal dome]

It has a default of Vector3.Up. It makes sense in 3D

But in 2D you should use Vector3.back I think

[shadow moon]

the perspective of the game is birds eye

[verbal dome]

Anyway, are you just trying to make a gameobject look at something in 2D?

[shadow moon]

rotate towards the player slowly yes yes

[verbal dome]

If you want instant rotation you can do transform.right = direction or transform.up = direction
But since you want it to happen over time you should probably get the direction's angle and rotate the player towards that angle

The Z axis angle, that is

[shadow moon]

i currently use ```cs
transform.rotation = Quaternion.RotateTowards(transform.rotation, Quaternion.LookRotation(TargetPos, Vector3.back), Agility * Time.fixedDeltaTime);

[verbal dome]

Yeah I don't think that's very robust in 2D since you would only want to rotate on the Z axis

This could rotate on other axes too

[shadow moon]

yeah im not seeing an easy solution here

[verbal dome]

I suggest this:
-Get a direction from A to B
-Use Vector2.SignedAngle(Vector2.up, direction) to get an angle
-Use Mathf.MoveTowardsAngle in Update with transform.eulerAngles.z

Another way would be
-Get a direction from A to B
-Set the direction's Z value to zero
-Assign the direction to transform.forward or transform.right

[swift crag]

Yep, that sounds reasonable.

Quaternion.RotateTowards is good if you need a 3D rotation, but there's no reason to use it here -- we only have one angle!

[wintry kiln]

Hello im trying to develop a 2d platform game and im having some trouble in the "door" part (like changing the rooms etc.). I cant seem to understand how to transport the player from a scene to the other and I was wondering if anyone was willing to help me or send me a tutorial that shows how its done

[swift crag]

So there are a few ways to do this

You can make each room into its own scene without a player object

You can put the player in a special scene that never gets unloaded using the DontDestroyOnLoad method.

Now you can load a new scene, then move the player into the right spot afterwards

You could also put a player object in every room, and just throw out the old player completely when changing scenes.

You'd have to store stuff like health separately from the player object in that case

You could also have a single scene and a bunch of room prefabs. When you change rooms, you destroy the old room and instantiate the new room

[vestal spruce]

[wind raptor]

I cannot seem to figure out how to make the build not automatically be full screen, and I don't know how to make it windowed/resizeable. I have added this code in one of my scripts, but it doesn't seem to do anything when I press F11:
if (Input.GetKeyDown(KeyCode.F11)) Screen.fullScreen = !Screen.fullScreen;

In my player settings, Full screen mode is set to Windowed, and Resizable Window is ticked.

[polar acorn]

I think it remembers what state it was when it last closed? The Windows shortcut for toggle fullscreen on any application is Alt+Enter. Try using that to make it windowed and see if it remembers? The code could have an unrelated problem

[violet agate]

i think i broke my unity idk what to do now

[hexed terrace]

press 'clear' and read the compile errors that don't go away -> research (google) -> fix

[polar acorn]

Looks like VRChat SDK errors. Are you sure you're on the right Unity version? If so, try what Carwash suggests, and if it persists, !vrchat might have better answers

[eternal falcon]

Join the growing VRChat community as you explore, play, and create the future of social VR! https://discord.com/invite/vrchat

[hexed terrace]

Is it the UdonSharp that points to VRChat ?

[polar acorn]

Ah, right, that's just an error saying there's other errors.

That shader could be from somewhere else

I don't think ShaderGraphZ is part of the SDK

[wind raptor]

I mean, I can never get it to change the state. It is only ever full screen.

[polar acorn]

I'm saying the code itself might have errors preventing it from running, and the project settings are overridden by the "last known state". Try the windows shortcut and see if it reopens in the same state. If it does, then we can take a look at why the code isn't swapping it

If not, then we can try to figure out why the window isn't changing

[wind raptor]

Alright well, an apparently relevant detail is that I'm using multiple displays. At the program's start, I set all of the connected displays active. When I comment out that line of code, the full screen toggle does work, but now I only have the one display visible.

K, from what I'm reading, it's not possible to have multiple windows for a single application

[wary sable]

Yeah generally you’d have to extend it the width/height of all the displayes. Unfortunately because people can have monitors of all shapes and sizes you are limited to the smallest they have plugged in

[frosty field]

best way to create "onGround" bool? someone told me to use raycast but im curious if there is better methods

[real grail]

either ray or collision

[frosty field]

well collision does work but it returns true even if im touching a wall

[steep rose]

A raycast, spherecast, overlapsphere and or checksphere will work

[frosty field]

so it allows player to doublejump while not being on ground

try this

[steep rose]

didn't I tell you how to fix this?

[frosty field]

well

you did i think

but you told me to use raycast which i dont really understand how it should work

[thorn oyster]

best way to create "onGround" bool?

[steep rose]

they return a boolean which you can use for ground checking

it is 1 line of which you need to do

[cosmic charm]

@frosty field The collision should be a bit lower than the character collision itself

[steep rose]

I don't think that returns a boolean instead an array of colliders, as per the documentation

unless I am missing something

[quasi dawn]

It returns true if the overlaparea finds the ground layer

Otherwise it'll be false

[polar acorn]

If you're using the new input system, you can bind an input action map to a device and use that map for one instance of an object.

If you're using the legacy input manager, you can create new bindings for player 2 and check for those separately

[polar acorn]

Basically: Start a line somewhere, point it in a direction, and ask "is there a collider in this line"

[steep rose]

ah yup, my bad, Also I missed the .length

[polar acorn]

The rest is just filtering on which kinds of things count

[swift crag]

3D and 2D physics differ quite a bit! I always get them mixed up

2D non-allocating physics methods can fill a list with values, instead of requiring a fixed-size array. It's a lot more convenient

(obviously, allocation is possible if the list has to grow, but that won't happen over and over)

[frigid sapphire]

I am making a clicker, very new to unity. When making an autocursor, the balance goes up way too fast, is there a way to slow it down?

[eternal juniper]

what does the script for it look like?

[polar acorn]

It'd depend on what you're doing to increase it but the general answer would be "use a smaller number"

[frigid sapphire]

Im assuming the whole script is okay to paste?

[polar acorn]

!code

[frigid sapphire]

Or only a small part?

[frigid sapphire]

Oh yeah mb 1 sec

first time using that, does this work? https://paste.ofcode.org/KfCUaDj5BU59EfJSbnKEbK

A little sphaghetti code but it shouldn't be that bad

[swift crag]

this indentation 😭

the first thing that sticks out to me here is the variable names

p1 and p1d aren't very obvious

i'd just call them price1 and price1Display, at least

[frigid sapphire]

Noted

[polar acorn]

First thing that jumps out at me:

[swift crag]

as for the rapid income

yeag

[polar acorn]

This is literally identical to add acm in Update

[swift crag]

it'll randomly skip frames

but it's very close to just slamming that in Update

[polar acorn]

1 * Time.deltaTime is literally the definition of "a frame"

[swift crag]

Why did you do that? Not trying to make you feel dumb :p

[wintry quarry]

ehh it's much worse than that

If the next frame is shorter than the previous frame, it will skip at least one frame

[polar acorn]

deltaTime is the amount in seconds the frame took to render. If you're waiting that long, that's ust going to wait a frame

[wintry quarry]

it's going to be entirely inconsistent

[frigid sapphire]

So what I thought would happen is that the WaitForSeconds would allow me to change the delay between each income

[polar acorn]

Along with added inconsistency if the framerate fluctuates yeah

[polar acorn]

It does, but the number you're giving it is "approximately one frame"

If you want it to wait longer than that, you'll need to give it a bigger number to wait

[frigid sapphire]

Yeah I tried WaitForSeconds(5 * deltaTime) but it barely changed

[swift crag]

WaitForSeconds(1f) would be more reasonable

[polar acorn]

That would be "five frames"

[swift crag]

why are you factoring in deltaTime here?

[swift crag]

(it still has Problems(tm), though)

[wintry quarry]

hoenstly using a coroutine here is a mistake if this is some kind of simulation

[polar acorn]

That's not a huge difference from one frame in the grand scheme of things

How long do you want to wait between ticks?

[frigid sapphire]

Around 1-2 seconds

[swift crag]

in that case, just wait for one second!

[polar acorn]

Then you should wait one to two seconds. The function WaitForSeconds takes in a number of seconds to wait

[swift crag]

Note that this is still going to be problematic. WaitForSeconds(1f) will wait for a little longer than one second, since the coroutine is only going to resume on the frame after at least one second has passed.

[polar acorn]

So give it the number you want

[swift crag]

I prefer this pattern:

float timer = 1f;

while (true) {
  timer -= Time.deltaTime;
  
  while (timer <= 0) {
    timer += 1f;
    // add money
  }

  yield return null;
}

Just make sure that you don't forget to add something to timer in that inner loop 😉

[frigid sapphire]

So I changed the wait time to 5f but from what I see is that it just delays when the loop starts and not how often the payout occurs

[swift crag]

This makes sure that, even if you have a very small interval, you get the correct amount of money

[frigid sapphire]

Ill give that a shot

[polar acorn]

Yeah, you would probably want that coroutine to loop. Right now it just waits, adds the amount, then exits.

[rare basin]

can anyone help restoring this window? i have somehow disabled it, it doesnt appear anymore even with gizmos enabled, particles selected in the hierarchy

[polar acorn]

Coroutines run up until they hit a yield, then pause for however long it is supposed to, then resume from where they left off until they either hit another yield or the function ends.

yield break being "End the coroutine early"

[polar acorn]

Shot in the dark, have you tried Window -> Reset all Layouts?

[rare basin]

yes i did

[frigid sapphire]

So if I wanted to loop it do I just delete the yield break?

[rare basin]

even restarting pc and unity :/

also cant find any info about it in the internet

[polar acorn]

You would also need to add in a loop of some kind

[frigid sapphire]

While (true)?

[polar acorn]

usually a while loop with some sort of exit condition. It won't be infinite as long as there is a yield inside the loop

[hearty hamlet]

anyone know why the ray isnt being fired, cant see the debug, it prints nothing i dont understand why

[polar acorn]

It's being fired, it just isn't hitting anything

You only draw the ray if the cast returns true

so if it doesn't hit anything, it won't draw anything.

[hearty hamlet]

ok thank you

still dont understand why it doesnt hit anything but thats something

no i dont think it is being fired

doesnt print the else statment either

oh wait it does mb

[rare basin]

#💻┃code-beginner message anyone 😦

[north kiln]

how have you declared groundLayer

[polar acorn]

So it seems that there are no colliders in the layers defined by groundLayer that are within rayLength units below this object's position

[icy sluice]

.interpolation = RigidbodyInterpolation.Interpolate;

the rigidbody 3D doesnt switch to Interpolate

[teal viper]

How are you confirming that?

[icy sluice]

via inspector

and general movement its jerky/snippy

when i manualy set it to Interpolate its smooth, but than client cant join and set its starting position

[polar acorn]

Put a log after you set it to ensure the function is running

[icy sluice]

it is running

Player.GetComponent<NetworkObject>().SpawnAsPlayerObject((ulong) PlayersOnline, true);
        yield return new WaitForSeconds(delay);
        //Player.transform.position = Spawns[PlayersOnline].position;
        Player.GetComponent<ArcadeVehicleController>().carBody.position = Spawns[PlayersOnline].position;
        Player.GetComponent<ArcadeVehicleController>().rb.position = Spawns[PlayersOnline].position;
        PlayersOnline=+1;
        Player.GetComponent<ArcadeVehicleController>().carBody.linearVelocity = Vector3.zero;
        Player.GetComponent<ArcadeVehicleController>().rb.linearVelocity = Vector3.zero;
        yield return new WaitForSeconds(delay);
        Player.GetComponent<ArcadeVehicleController>().carBody.interpolation = RigidbodyInterpolation.Interpolate;
        Player.GetComponent<ArcadeVehicleController>().rb.interpolation = RigidbodyInterpolation.Interpolate;
        yield return new WaitForSeconds(delay);
        Player.GetComponent<ArcadeVehicleController>().carBody.isKinematic = false;
        Player.GetComponent<ArcadeVehicleController>().rb.isKinematic = false;

everything but interpolation gets applied

[polar acorn]

Then if it's not set in the inspector, either you're looking at a different object or something else is setting it back after this

[icy sluice]

im not, i know with what im working with

[teal viper]

Add a log...

[icy sluice]

i checked with log

i also changed the name of an object when i runned it

[teal viper]

Add the GameObject as the second parameter to the log as well, so that you can confirm in the editor.

[teal viper]

What does it print?

[icy sluice]

"babaroga"
just what i set it to print

now wait

now that i have asked for help, it should fix it self in 10min

[teal viper]

Print the variable that you changed as well as the object name.

[untold shore]

Hey, I know this is a little idiotic, but I don't even know where I should look to research how to get this. Currently, I have a card prefab that's going to hold all my sprites, and my sprites are in an array. What I want is that sprite to change based on the array (where itll pick a sprite, that sprite will show up). I have a canvas, but I don't know where to go from there. Do I make an object that the array attaches to? Do I need to write an entire script to make that sprite change? I don't know. I'm going to put some images, don't know if they'll help, but any ideas of what to do?

Here's that code if you're wondering:

public class CardDisplay : MonoBehaviour
{
    public Card cardData;

    public Sprite cardSprites;
    public Sprite[] mainCardSprites;
    public Sprite[] specialCardSprites;

}
``` Thanks

[timber tide]

What's the idea here? Does each card have a single type of sprite, or do you want a single card to have multiple images?

[untold shore]

A card has a single sprite, so the element 0 would hold one card, Ace of Cryptids, which would be a singular card (we have a placeholder for it currently.)

[timber tide]

So two ways I'd tackle this. One, being the basic idea of having multiple prefabs, each using a single card sprite. Two, scriptable objects can be your plain data you reference such that you have a single card prefab that reads from these data types.

Your idea isn't that bad either. Is there a problem with your implementation because if it works it works ;p

[hallow hound]

omg im so annoyed, the code was working perfectly, change some positions, started giving errors, ctr z to what i changed, still same errors and now 1 hour later still DONT KNOW WHAT is giving the errors 😭

its says that the initialization of a class is null but i didnt changed any of that

[wintry quarry]

You need to debug your code

[hallow hound]

Yeah! i added a lot of logs, and evrything is working EXCEPT for a json wrapper, that was working fine, didnt touched and now doesnt work and dont know how to fix it

[untold shore]

Yeah, the cards are just not showing up which is weird. Don't know where it's not connecting. (The thing that shows up should be the card sprite)

[hallow hound]

look, the log says that the data was loaded but when i log the voxelDataArray it says null

but i redid the json, with only one VoxelShape with super basic data and it still says null, all this because i change a position from 1 to 0.5f, but i revert it and still giving errors

[timber tide]

Sprite is just an object of a class. You've not referenced the actual component on the gameobject that handles the display which is a class of Image
https://docs.unity3d.com/2018.2/Documentation/ScriptReference/UI.Image.html

If you want to bind it at runtime, you need to explicitly grab the image component via GetComponent then access the sprite property.

Or, if you want simplicity for now, consider the first option I mentioned and just custom make each card into its own prefab

[untold shore]

Which way would be better for the game? If its more difficult Im willing to learn.

[hallow hound]

that's what is in the json, it is supposed to be correct but i dont know why, copilot says that the problem is when it loads the data and then it logs it as null is because the json doesn't match with the class but it is supposed to be correct!

[teal viper]

VoxelShape needs to be marked as serializable

And I'm not sure if that json is valid. Did you serialize it in unity as well? Or type manually?

[timber tide]

if you had hundreds of cards, then using scriptable objects and a single prefab approach is ideal. But, having knowledge of how prefab variance works would make a prefab workflow fine too

[hallow hound]

omg that was it

I DONT KNOW HOW i deleted that without knowing

thanks so much

[naive pawn]

that json's definitely valid, not sure what you mean

[teal viper]

I never write jsons manually, so get confused with it's syntax sometimes. And I didn't say that it's definitely invalid. Just that it might be if they have written it by hand.

[naive pawn]

if it was invalid the ide probably wouldve highlighted errors

[late abyss]

I have some screenshots of the game I'm still developing. Just to double check, does it look like I have defined what sounds I want to be used in both Unity and Visual Studio? I have a problem with my bird where when it hits a pipe, the game over music plays, but not when the bird goes off screen. Any suggestions?

[naive pawn]

(or it would mistake it for jsonc...)

[naive pawn]

pause while in playmode and check the y position to see if it's where you expect

[late abyss]

I can try that. I could also try to play the sound in the game over function

Quick question, what method should I use if Im trying to get a random image from this image array?

    public void Start()
    {
        cardSprites = GameObject.Find("CardDisplay").GetComponent<Image>();
        Image[] mainCardSprites = Resources.LoadAll<Image>("Cards/Main");
    
        Image[] specialCardSprites = Resources.LoadAll<Image>("Cards/Special");
    }
/// (another function)
    {

            cardSprites = /// this should be a random image from mainCardSprites;

Thanks, just really confused and having trouble finding it for images.

[rocky canyon]

its just a random number between 0 - .length right?

collection[Random.Range]

    public void AssignRandomCard()
    {
        int randomIndex = Random.Range(0, mainCardSprites.Length); 
        cardSprites.sprite = mainCardSprites[randomIndex];
}```

capital L i believe

[untold shore]

Thank yall so much!!!!!

Hey, it keeps giving me this error with that, any ideas?

(I'm using Spawn's, but removed .sprite since CardSprites are images)

[naive pawn]

you don't need to stringify that, Debug.Log does it for you

[untold shore]

Yeah, its something with the naming of the folders. Need to figure out how to get them in (changed it to sprites for a second to see if I could make it fix that way)

[rocky canyon]

whats something with the naming? whats happening?

[rocky canyon]

sorry, i just assumed it was a sprite

[untold shore]

It's the folders I guess? Here are the folders - it won't let me go into the folders to access the sprites

[untold shore]

All good man!

[rocky canyon]

soo Sprite[] and Image[] neither one populate?

where do u run this code? can u share the full script? !code

oh true... why do u have "Main", you'll have to drop down b/c its a SubFolder

• Cards
  • Main

Still gives this problem for some reason? (It equals 0)
I'll get the entire script on a pastecode, its a lot

well u can just give us the relevant parts

Right, hold on rq...

Ooohh, so I would have to do Cards/Main/ChineseZodiacs?

Omg. its because I forgot to do sprites.

(context they were game objects and I had sprites in a different folder.)

Thank y'all so much for dealing with my dumb brain 😭 😂

[upper prawn]

Hi, I'm looking for advice on managing all my crop models/colliders/info for a stardew clone.
I'm thinking I would have some kind of lookup table generated from a config file, where I can associate seeds to the crop growth stages, and harvestable items, and animations.
However I don't know how to dynamically load/select the models for these things. It seems like I would use prefabs, but I'm still not sure how to handle all this dynamically. Any advice?

hello everyone, this snippet of code is attached to a cannon script i have. when the platform the cannon is on (say, a vehicle or a ship) rotates along any axis, it does not account for the root body's rotation despite my best efforts. how do i make the code use either global rotation or account for the root body's rotation? https://paste.ofcode.org/d45vNsnMHBaiG6MxQa6UBh

[nova kite]

Is there a channel that gives you a road map to how to start because every time I try and learn game development I give up in two hours, I tried everything and idk what to do

[alpine fjord]

I suggest doing the essentials and junior programmer paths. !learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[nova kite]

Does it teach Unity in a more broad level because I hate just following a specific game creation on YouTube, when I do that it’s all fine but then I want to do something of my own and I don’t know how to even begin

I wanted to make a simple game of dragging a ball and shooting it like those games where you hit blocks, just to see how that can work, I made a ball object and two walls and got stuck writing a script for the ball to draw a line in front of it when you drag the mouse

[teal viper]

Yes. It teaches you how to work with the editor and unity API. A little bit of C# too.

You should remember that gamedev is a complex subject. Asking for a road map to learn it is like asking for a road map to master quantum physics.

[nova kite]

I’m more familiar with c++ since we are learning that in college and it is kind of similar but I just don’t know how to learn the libraries and functions that will help me execute these actions

For example the mouse detection at a certain position

Or dragging, or drawing lines or anything

[teal viper]

As I said, some of the most commonly used API is covered in the pathways.

Other than that, you'll need to get used to researching and learning on your own.

Google should be your most used website.

[nova kite]

I tried learning with chatGPT but it just gives me the answer which doesn’t help lol

[alpine fjord]

Do NOT use chatgpt when you're learning. It's wrong just as often as it's right. And any code it gives you, is iffy.

[nova kite]

What do you search when you search for specific problems? Because it’s even version sensitive, for example I saw a video about mouse detection in Unity and it showed a line of code that starts with Mouse(being an object) but in my version I got an error because Mouse wasn’t an object

See I thought it’s a double because the pixels in the video had a dot too

And also there was a world screen function which from what I understood is the position of only the inside rendered screen and not the actual screen

And got completely lost haha

[alpine fjord]

I read something awhile ago, chatgpt was asked to multiply two 5 digit numbers. And it gave you the wrong answer.

[nova kite]

I’ll try and follow the general API tutorial and see if I understand

[nova kite]

It kinda taught me calculus 1 this semester maybe it has bad days lmao

[nova kite]

This looks like exactly what I was looking for tbh, thank you!

I wish I could use c++ tho I’m way more comfortable with that haha, is there a script by any chance that allows you to do that with Unity

Welp I’ll just learn c# then haha

At least no pointers

Is that a game engine?

Oh lol

I tried unreal but I don’t like the interface and creating a 2D game on it is weird

And not many tutorials because everyone are using the other option that’s like a coding blocks thingy

Thank you! I’ll take a look at the beginner tutorial first so I don’t bother you with questions that I can get the answers to there!😅

[alpine fjord]

Google is your friend.

[nova kite]

It feels too broad searching a specific problem on google🥲

I’ll follow the basics for now tho, get familiar with the interface

Thank you guys, this motivated me again haha

[alpine fjord]

Well, you'll have to get used to that.

[nova kite]

Yes I just need to understand how to apply an answer that I see on google to my problem🥲

Because usually it involves some level of pre understanding the problem

[teal viper]

Don't search for a specific problem. That's not how you solve problems. Debugging is how you solve problems. Searching is for finding API and techniques to implement a certain feature.

[nova kite]

So you can infer what you need to take from it

[nova kite]

When searching for an API, are you supposed to learn the entire thing or just copy paste the code

[teal viper]

Then it means that you're missing some prerequisite knowledge. Research it first.

[nova kite]

Because that feels like not learning if so

[teal viper]

You're supposed to learn everything you don't understand. Not just copy paste.

[rocky canyon]

u specify ur final search to ur problem by debugging the bigger problem into smaller more specific problems..
the ones with simple answers a dime-a-dozen on search engines

[teal viper]

It is when you're getting started. Eventually, there would be more things that you understand on the get-go.

[nova kite]

I see, and then how do you remember the exact function that helped solve the problem in that case or the exact line of code

[rocky canyon]

u remember out of habit

[nova kite]

Yea the most I’ve done with code so far is some basic data structures😅

[teal viper]

Imagine you're building a rocket and you don't know anything about rocket engines or the chemistry of it's fuel. You're not gonna build the rocket until you learn these more basic concepts/building blocks.

[nova kite]

Oh I’ve done classes and objects and polymorphism

I just never had the opportunity to apply it to anything

[nova kite]

That’s true

[rocky canyon]

coolio.. u'd have opportunities in unity

[nova kite]

That’s what I’m looking forward to😄

[toxic frigate]

anyone? im sorry that its a lot of math but its pretty important and im pretty lost

i did some more tinkering and used Vector3.ProjectOnPlane but it didnt do anything

[teal viper]

It's not entirely clear what the issue is just from the code and your explanation. Maybe a video of the issue could be helpful. Also, the code you shared skips a lot of the context(like where it is called from and what parameters are passed in).

[toxic frigate]

i cant record a video at the moment, are screenshots fine?

also I added the function where the calculate angle function iss called https://paste.ofcode.org/8hFvVBBnGGyWsEiJZzdPgt

i have some ships firing at each other, this is when the ship's tilt is negligible, and its splashing roughly around the target

and when its tilted like this it ignores the root rotation and splashes into the water

and conversely when its tilted the other way it overshoots

this is the best way i can visualize it at the moment i would record a video im not at my main computer at the moment

[teal viper]

That's quite a lot of code for something as simple as rotating an object. I'd suggest making a method that takes the origin and target positions as well as the curve parameters(or uses class fields for these).
Another thing is that you're using local rotation which could be contributing to the issue. Use world space rotation.

[toxic frigate]

yes

yes

how would i convert it to world space?

yes

this is the whole hierarchy

yes

[acoustic sequoia]

Hey does anyone know how to pass in a transform into the inspector of a unityevent?
ive tried this:
public UnityEvent<Transform> onSelect, onDeselect, onClick;
invoking like this:

  {
    onSelect.Invoke(transform);
  }```

hmm. neverming, there was just a unity editor display problem. fixed it by reopening my proj

[elfin sigil]

Hi! Im a little stuck trying to alter this code. Currently, it shoots a projectile in the direction the player is moving. I'm wanting to set it to shoot it in the direction the mouse is in? Thanks

 ```   private void ThrowProjectile(int projectileIndex)
    {
        GameObject projectileInstance = m_projectilePool.GetAvailableInstance();
        projectileInstance.transform.position = m_projectileSpawnPoint.position;
        projectileInstance.SetActive(true);
        Projectile projectile = projectileInstance.GetComponent<Projectile>();

        Vector2 baseDirection = m_character.FacingDirection; // Get the character's current facing direction.

        float angleOffset = (m_sheet.spread / m_sheet.projectileCount) * projectileIndex - (m_sheet.spread / 2.0f);

        // Rotate the direction by the spread angle.
        Vector2 direction = Quaternion.Euler(0, 0, angleOffset) * baseDirection;

        projectile.Throw(DamageSolver.SolveDamageOutput(m_character, m_sheet.damageDescriptor), direction, m_sheet.projectileSpeed);
    }
}

}

[astral falcon]

So like an ego shooter in the middle of the screen or like a ground indicator with your mouse to throw at?

[visual linden]

Hey Soho,
you'd take the position of the player, minus the position of the cursor, and normalize the result to get a direction vector towards the mouse.

[slender nymph]

I'm assuming 2d, which means you probably have an orthographic camera, you can use ScreenToWorldPoint to get the mouse position in world space, then direction is just (endPosition - startPosition).normalized

[elfin sigil]

Sorry I should have clarified, this is 2D. I tried experimenting with ScreenToWorldPoint but wasn't having much luck

[slender nymph]

Show what you tried with it

[visual linden]

I can recommend using OnDrawGizmos to visualize your results from ScreenToWorldPoint, and the direction you get as a line. It can help you quickly see what kind of results you're getting and how they differ from what you expect.
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.OnDrawGizmos.html

[elfin sigil]

I didn't save it unfortunately but I'll look into it and give it another shot. Very new to this, thanks

[elfin sigil]

Thanks thats great to know, I hadn't got that far though haha. My attempt would crash or the projectile wouldn't move

[slender nymph]

Note that it will likely be easier and make more sense for you to use Debug.DrawLine instead

[elfin sigil]

        {
            GameObject projectileInstance = m_projectilePool.GetAvailableInstance();
            projectileInstance.transform.position = m_projectileSpawnPoint.position;
            projectileInstance.SetActive(true);
            Projectile projectile = projectileInstance.GetComponent<Projectile>();
            
            Vector3 mouseWorldPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            mouseWorldPosition.z = 0; 

            Vector2 directionToMouse = (mouseWorldPosition - m_projectileSpawnPoint.position).normalized;

            float angleOffset = (m_sheet.spread / m_sheet.projectileCount) * projectileIndex - (m_sheet.spread / 2.0f);

            Vector2 direction = Quaternion.Euler(0, 0, angleOffset) * directionToMouse;

            projectile.Throw(DamageSolver.SolveDamageOutput(m_character, m_sheet.damageDescriptor), direction, m_sheet.projectileSpeed);
        }``` 
This crashes the game when I use the ability

[astral falcon]

Does it crash the editor?

[elfin sigil]

No, just the game view

[astral falcon]

Gameview you mean build runtime?

I am not aware of a crash only crashing a view 😉 do you get any logs?

[elfin sigil]

No, just in the editor view

[visual linden]

What does your Throw method in Projectile look like? I don't see how the rest of the code would cause a crash.

[elfin sigil]

There's no other reference to the mouse in the project fyi

if that could be an issue

[slender nymph]

What do you mean by "crash", is the editor actually closing or is the entire editor perhaps freezing, or is play mode just pausing unexpectedly?

[elfin sigil]

The rest of the code: ``` public class ProjectileAbility : ActiveAbility<ProjectileAbilitySheet>
{
[Header("References")]
[SerializeField] private Animator m_animator = null;
[SerializeField] private InstancePool m_projectilePool = null;
[SerializeField] private Transform m_projectileSpawnPoint = null;

    [Header("Animation Parameters")]
    [SerializeField] private string m_fireAnimationParameter = "fire";

    public override void Init(CharacterBase character, AbilitySheet settings)
    {
        base.Init(character, settings);

        Debug.Assert(m_animator, ErrorMessages.InspectorMissingComponentReference<Animator>());
        Debug.Assert(m_animator.GetBehaviour<StateMessageDispatcher>(), string.Format("{0} not found on the projectile animator controller", typeof(StateMessageDispatcher).Name));
    }

    protected override void Fire()
    {
        m_animator?.SetTrigger(m_fireAnimationParameter);
    }

    public void OnChargeAnimationEnd()
    {
        if (!m_character.dead)
        {
            for (int i = 0; i < m_sheet.projectileCount; ++i)
            {
                ThrowProjectile(i);
            }

            TerminateCasting();
        }
    }```

Wait sorry, its pausing the game. The projectile fires but it stays on the character, and they can no longer move.

[astral falcon]

Any error in the logs?

and ++i should be i++, right?

[slender nymph]

Yeah sounds like an exception with error pause enabled

[visual linden]

In your Console window, there's a little button called "Error pause" - When this is ticket, it will pause the game when an error is thrown.

[slender nymph]

Nah, those work pretty much the same as the incrementor for a loop

[elfin sigil]

Nothing in logs. Thanks for the tip 🙂

[astral falcon]

Oh really? never used it and thought it will increment with i instead of 1, thanks 🙂

[void thicket]

It’s same when you don’t use the value

[astral falcon]

But in this code, its being used to access an array with i

[slender nymph]

Nope, ++i just increments by 1 before returning the value of i. In the context of the for loop it works pretty much identically to i++

[visual linden]

Make sure you're not filtering out the log messages

[void thicket]

Not in the same line

ThrowProjectile(++i) and ThrowProjectile(i++) would be different

[astral falcon]

The more you know 🙂

[elfin sigil]

🤦‍♂️

I now know how to use the console

UnityEngine.Input.get_mousePosition () (at <c8b1b15e0c1a4cccb2a9ed91e2ed21c8>:0)```

[astral falcon]

So you need to use the new input system to get your mouse position 🙂

https://docs.unity3d.com/6000.0/Documentation/Manual/Input.html

[void thicket]

Oh yeah, idk why it has to block the legacy one, but there is also option to use both iirc

[visual linden]

Alternatively, you can switch to "Both" in Player Settings. But I would also suggest learning the New Input System.

[astral falcon]

Yes, please step away from that very old one. once you get the grasp on the new input system, its so comfortable to use and play around with

[visual linden]

A lot of tutorials and courses use the legacy input system though, so if you're trying to follow along with something, it might be worth simply setting your project to "Both" so you're not blocked in your current learning journey.

[ebon crow]

Hi everyone

[burnt vapor]

Hi there, if you have a question about your code then please share here and don't forget to share the actual code

[tired hull]

Hi im new to unity and im trying to add boundarys to my space shooter game but i get these errors in the console, is there anything in my script for boundarys i should change to fix this?.

[gaunt cipher]

I'm assuming you took this code from somewhere but that's a non-existent variable. So you'd add something like private float shipBoundaryRadius = 5.0f; up at the top.

[tired hull]

i got the project from this tutorial https://www.youtube.com/watch?v=NzSEVjkVPk4&list=PLbghT7MmckI4IeNHkPm5bFJhY9GQ0anKN&index=3

[teal viper]

Then you probably didn't copy it correctly. Follow the tutorial again and make sure you didn't miss anything

Also,configure your !ide, as you wouldn't be able to get help here otherwise.

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[tired hull]

found out what was wrong i didnt add shipboundaryradius at the top, my bad

[burnt vapor]

Please do take time into configuring your editor because errors like these are solved much easier then

[visual linden]

Great time to read up on scopes
https://www.tutorialsteacher.com/articles/variable-scopes-in-csharp

[teal viper]

I don't see how that's related to scopes. Variable declaration maybe

[fierce lynx]

Do y’all allow talking about C++ here? I’ve seen some post online where people talk about cpp in unity communities such as in Reddit.

[languid spire]

no we dont

[fierce lynx]

ok

[teal viper]

If it's related to unity, yes. But that's unlikely

[grand snow]

you can use native code in unity if its built into an dll/so/dylib (or if the source code is included for ios/android)

[visual linden]

Ugh, you're right. I only glanced at the tiny screenshot on my laptop and jumped to conclusions. But I'm sure they'd do good learning about scopes regardless :D

[teal viper]

You could do many things. But that would make it only vaguely related to unity if at all.

[wintry kiln]

hello im trying to develop a 2d platformer game and ive been struggling with the changing of the scenes when i go through a door. im not sure on what type of scripts i have to use: i tried with a script for the door but i cant seem to be able to choose the position on where the player ge transported so idk what to do now. if anyone knows how to resolve this please text me

[finite dove]

I'm not to sure on what you wanted to do, so im assuming that you want to make player to transport to other scene and set player position, in that case you can use ScriptableObject or instantiate the player from new scene you have.

[wintry kiln]

im trying to write a script that i can attach to the doors and can "transport" the player from 1 scene to the other. im gonna try to use the scriptable object and see how it goes

[dark laurel]

You don't need an SO for this, and that's probably more complicated than what you're looking for. Drop a GO in the scene called "Teleport1Exit", link it in a script, and then when the player walks through the teleport entrance, set the player's transform location to the teleport1exit's transform location.

[wintry kiln]

ohhh thank you so much

im gonna try it right now

[snow warren]

Ok i am having a server problem here

i wonder if there is an easy fix for this

I am using Playfab and in playfab there is no way for finding out if your friend is currently online or offline so i wrote a script that updates the friends data on server and add to it 1 minutes ahead of its timezone
if someone in the same time zone is friends with this guy he will get the timer 1 minute ahead always from his time zone

now when the player is offline the 1 minute ahead wont be updated and seeing this if time > server.aheadtime then the game would know that the friend is offline

but for someone who isnt in the same time zone this cheap fix wont work

is there a way to use a universal time

or something similar

[languid spire]

we are not here to provide support for 3rd party assets

[snow warren]

in short my question is how to convert other time zone time into your local time zone time

[languid spire]

look at the C# DateTime class

[snow warren]

let me

[grand snow]

You can use DateTime and DateTimeOffset and work with UTC to have a "timezone less" time.
DateTimeOffset can be used to easily get unixtime which is best for sending and storing a timestamp (which should also be stored in UTC 0)

[snow warren]

i found a better way

no matter the culture info
if i change the culture code to "us" then i will get us time zone

i can then process requests based on that time only

[grand snow]

you want to avoid timezones with time calculations

[languid spire]

that wont work

[snow warren]

ohk

any other options?

[languid spire]

yes use UTC Date/Time

[grand snow]

DateTime.UtcNow is your friend 🙂

[snow warren]

lol ok

any examples on how it is implemented?

[grand snow]

https://learn.microsoft.com/en-us/dotnet/api/system.datetime.utcnow?view=net-9.0#system-datetime-utcnow

[snow warren]

wait time zones are utc + something

so with utc you only get the utc time

no additions to it with respect to region

[languid spire]

and you can convert UTC time to Local Time using the DateTime class

[snow warren]

seems cool

[dark laurel]

(this username is super annoying because you can't be @'d easily FYI)

Whenever you deal with dates, the time zone of the date is irrelevant - you should always be handling it (or thinking of it) as a UTC based date - if you try to get into the business of doing time zone stuff, you're gonna mess up, trust me. It's way more complex than you think.

If you need to make a date, use DateTime.UtcNow (not DateTime.Now!) and increment/decrement it with timespans using the overloaded operators (sounds complex, looks simple):

DateTime oneMinuteFromNow = DateTime.UtcNow + TimeSpan.FromMinutes(1);

whenever you render the datetime and need to show it to a user in local time, then you'll display it using the culture info, but for things under the hood, you should always treat dates as UTC based so you dont get into the bugs of time zone stuff

[snow warren]

this is great example

i am gonna use it right away and see if it works

[dark laurel]

maybe change your username or display name to Code Red while you're at it? 😉

[snow warren]

lol

why?

Here changed it for this server only
good luck

[dark laurel]

so I can type @snow warren instead of scrolling up to find a message of yours and hitting reply 🙂 (also that ascii typeface is awful and hard to read sorry notsorry)

[snow warren]

lol mentioning is a bit outdated
used to do that back in 2019

just slide and reply

[snow warren]

which encoding has the most characters
i think ascii

ascii uses 4 bytes for one character

whereas in C++ by default its utf which stores a character as one whole byte

C# by default uses 4 bytes as one character so ascii by default

am i right or wrong?

[grand snow]

er wat

c# uses utf8 for strings always and its variable in length what a char is

[snow warren]

*utc *utf

type mistake

[snow warren]

so how does its character is 4 bytes long

sorry forgot 2 bytes

man i gotta wash my brain

[elfin knot]

starting a 2d project for the first time in unity
what's a good pattern for organizing different screens/views ?
for example overworld and combat views ?

[languid spire]

actually utf16, a char is 2 bytes

[snow warren]

[dark laurel]

Start with one scene, and go from there. You'll find what works for organization as you go - there's a lot of different opinions on it

[teal viper]

A char is just 2 bytes of arbitrary data. The way you interpret it is what matters.

[gentle bone]

google knows better

[dark laurel]

@elfin knot (additive and async scene loading aren't really a problem as you get started)

[elfin knot]

so usually those are split into different scenes ?

[snow warren]

so utf-8 uses 4 bytes

how??

[dark laurel]

As far as screens/views, I'd say the same. When a rendering class is too big (your opinion on "big") then break it apart.

[elfin knot]

ok, i'll start with overworld and by the time i get to other screens it will probably be more apparent

[dark laurel]

They could be, but I do almost all of my games in one scene (!) and it works just fine, even for rather large games. In general I do 2d/ui games though - the one 3d game in our portfolio is just 2 levels so we don't need to do a lot of scene stuff

Make sure you distinguish Scene and "screen" - a scene is a unity "box" where all the game objects exist. A "screen" is a UI idea that you might create with a single game object (or script) or dozens

[elfin knot]

cool, ty for sharing
and btw, when it comes to ui, do people usually use ui libs like ui toolkit, or 2d objects ?

like i have game objects and game board
but also things like esc menu

in 3d i'd use ui toolkit for esc menu
but since it's 2d i'm not sure how people usually go about this

[snow warren]

unity has its own UI library

tho you can use third party UI library by their C# bindings like Imgui etc

depends on what you prefer

[dark laurel]

uitoolkit is like... XML for unity

[dark laurel]

"unity ui" or "IMGUI" (immediate mode gui) are .. maybe more common? to do 2d UI stuff

I do all my stuff with unity UI

[languid spire]

UIToolkit is based on the HTML FlexBox model

[dark laurel]

(IMGUI is kind of weird)

I'd suggest UnityUI if you're just interested in things like huds or 2d based ui games

[elfin knot]

just in general, not a specific library, just to understand if it's more common to use 2d game objects to make UIs in 2d
or use specialized UI libraries

[dark laurel]

it depends on what you're trying to do 🙂

UIToolkit is like steve said - html-ish? xml-ish? based on flexbox model - it's like.. great for quickly laying out input boxes, forms, etc.. maybe more for data applications over games

uGUI (aka "unity ui") is like.. draw to a canvas, put this image at 100, 100, have this button send some event back to the code

[elfin knot]

for game board and game pieces i will use 2d game objects
but for things like hud and esc menu, main menu and so on i'm not so sure

[burnt vapor]

Different formats allow for more characters and therefore also things like emojis and such. Compared to ASCII which is strictly letters and numbers and a few other symbols

[dark laurel]

IMGUI is more for like programmers and people doing things in the editor (like assets)

[languid spire]

you are missing the point. UIToolkit is easily user extensible, IMGui is not

[dark laurel]

95% sure you want to use uGUI

[elfin knot]

i will look into ui libs then, wasn't sure if people use them at all when making 2d games

[snow warren]

UGUI or Unity UI is much better when it comes to UI development
more control and animation controls and many other stuff plus you can control UI behaviours with C# scripts as well like loading screens logins and many other stuff

[elfin knot]

this really helps

[polar kraken]

Hey all,
I want to prevent character to enter water area. What is the best way to do that ?

[languid spire]

best? Difficult to say. Easiest? Surround your water with a Collider

[swift crag]

Give us a few more details -- is this 2D? 3D?

[polar kraken]

Water areas are not in simple shapes, does it make sense to use Probuilder to create a mesh and use that as MeshCollider ?

[swift crag]

Do you have water surrounding the entire play area, or is this more of a lake?

[languid spire]

you can use multiple box colliders for example

[polar kraken]

More lake and rivers. And it is 3D

[swift crag]

How did you create the bodies of water?

[polar kraken]

It is more complex than using multiple box colliders. Also I wanted to make it easier for myself and teammates to reduce editing time.

[polar kraken]

Except rivers, other water bodies are created by multiple planes

[swift crag]

okay, and the player isn't going to be flying high over the water?

it should just be an impassable barrier

[polar kraken]

Also I've tried to use raycasting and find out if the character is near water. I can figure that out but the issue is, it got time consuming to prevent player stop before that. Also I'm not sure how does it look like when other conditions happen. Like in strafe mode or when jumping.

[polar kraken]

No

[polar kraken]

By collider ?

[swift crag]

I was just about to suggest that! Pushing the player back in-bounds would be a little difficult

You could draw a path around the water and then create box colliders along it. That'd be pretty easy to do with an editor script and the Splines package.

[polar kraken]

For instance, I made this one by probuilder. But still I'm not sure if it is a good approach or it might be heavy because it is complex mesh collider.

[swift crag]

I don't know too much about mesh collider performance

[polar kraken]

Yup, exactly. I'm using Kinematic Character Controller but it is a little hard to figure out how things are handled there. I've added some kind of resolving overlap but it doesn't look good.

Put a bunch of box colliders down by hand around the perimeter 👅

[languid spire]

That is exactly what I said but it was 'too much work', lol

[polar acorn]

If these are static bodies of water and aren't procedurally generated or anything then placing colliders by hand is 100% the best course of action.

Sometimes, tedious data entry is just part of the job. Unless you've got a ludicrous amount of water, programmatically doing it is likely to take longer and not really be very generalizeable.

[swift crag]

I'd try to outline it and then generate the collider from that outline, at least.

[stuck palm]

void OnDisable() {
    if (renderers == null) {
      renderers = GetComponentsInChildren<Renderer>();
    }

    foreach (var rdr in renderers) {
      var materials = rdr.materials.ToList();

      if (materials.Contains(outlineMaskMaterial)) {
        materials.Remove(outlineMaskMaterial);
      }
      if (materials.Contains(outlineFillMaterial)) {
        materials.Remove(outlineFillMaterial);
      }

      rdr.materials = materials.ToArray();
    }
  }

I have this code thats meant to remove materials from a scene. However it is not doing this, why is that? There are no errors, and the values are all set. No idea whats happening here

[swift crag]

materials contains instanced materials

they're copies of the originals

[stuck palm]

wait a sec

the outline has (instance) (instance) lmao

wtf

[swift crag]

well, yeah, you have "OutlineMask (Instance)" here

If you assign that into material or materials, it gets instantiated again

[long jacinth]

hello so i have these states and tabs for buildings i want it so when u hover over each button it shows what states have that building and what dont the problem is that its not even changing the color when i built and its only doing for one building here is my code:
https://paste.ofcode.org/39b2Vj6GEnzZqVtLPHuHwnM

[swift crag]

You can use sharedMaterial and sharedMaterials to avoid instantiation

Of course, you'll then have to make sure you aren't modifying a material that's shared by many renderers

[stuck palm]

that's the problem yeah, I'll have multiple different characters using the same material

I don't understand the reference that the script has then. it's not in the renderer list, so where is it even being used?

[swift crag]

Is "OutlineMask (Instance)" an asset that shows up in the project window?

[stuck palm]

no, OutlineMask is the one inside resources

[grand junco]

Hi everyone! Looks like Im struggling with pretty default issue so I will be glad to hear any advices on how to resolve it.
I have 5 cubes of the same size and with same Y coordinate and use them as floor floor. Also I have cube which should slide on them some distance after rb.AddForce(force, ForceMode.VelocityChange.) called in my code. It slides as expected until it reach border between two of floor object - then it stops(red line logs on screenshot shows what force my code tries to apply each fixed update). My only idea how to resolve it - is add some forces in up direction to help rigidbody moving on seams but it looks bad

[swift crag]

The (Instance) suffix implies this was read back out of a renderer's material or materials property

[stuck palm]

yeah, I think there's something wrong somewhere with what I'm trying to set, I'll have a look at that

why is the render list not something you can modify directly btw?

[swift crag]

"Render list"?

[stuck palm]

like you have to make a copy and and then assign that copy back

[stuck palm]

material list I mean

[swift crag]

Because Unity isn't actually using an array of Material objects internally

it's something off in native code land

materials is a property that creates an array of Material objects

(or uses an array to reconfigure the renderer)

[long jacinth]

anyone knows a solution?
I know that its only highlighting one state and i left it there for now

[lapis parrot]

why when i try to add text it doesnt work?

[grand snow]

Ty

[burnt vapor]

Gonna need some more context if you want help. Code, maybe screenshots

[fringe plover]

Im not sure but it may be problem in the button script, or something realted to it.

Try debugging everything, like, check the button stats on press and etc.

[long jacinth]

ok

[grand junco]

Resolved it by replacing box collider with capsule collider for sliding cube

[swift crag]

I've had trouble with this before -- collider edges are always a little fiddly

[opaque owl]

does anyone have any idea what could be causing this please 😭 this is killing my hobby project
-# unity 6000.0.19f1

[verbal dome]

Close unity, delete your Libary folder in the project folder and relaunch the project

That's the first thing I do when unity starts to hang

Although it hasnt really happened since I moved to LTS

[swift crag]

yes -- mangled asset data can cause very weird behaviors

the Library contains data generated from your assets, as well as stuff like compiled shader variants

The editor will forget which scene you had open, so it'll open into a blank scene

[opaque owl]

thanks ill try that, for the record im upgrading to 6000.0.31f1

[swift crag]

This is similar to running Assets > Reimport All, although that doesn't forget things like the currently open scene

[severe onyx]

how would I go about moving an object across the screen in a wave pattern ie a constantly changing direction vector

[swift crag]

there are two main ways you'd do this

the first is "iterative": you add a small amount to the current position every frame

[polar acorn]

Wave Patterns usually mean Sine waves.
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Mathf.Sin.html

[swift crag]

consider something like this

Vector3 vec = Vector3.right;
float angle = Mathf.Sin(Time.time) * 45;
vec = Quaternion.AngleAxis(angle, Vector3.forward) * vec;
transform.position += vec * Time.deltaTime;

This would steer back and forth across a 90 degree range

The other approach would be to just directly calculate a position

Vector3 pos = default;
pos.y = Time.time;
pos.x = Mathf.Sin(Time.time);
transform.position = pos;

[severe onyx]

yeah I was imagining something like the latter. using a sine was what I expected but I kinda blanked on how to calculate it over time. using Time.time seems very obvious in hindsight, duh

works like a charm, can scale it with a speed variable and add it as an offset if the starting position is non-zero, perfect

should I be worried about performance if there's a lot of entities on screen using that function?

[verbal dome]

I don't think there's a more performant way to do it, at least with gameobject workflow

From the two approaches Fen provided I'd assume that the second one is cheaper

[long jacinth]

i think i found out

at least for why its not upgrading part

            {   
                if(hovering != null && instantiatedButton != null)
                {
                    hovering = instantiatedButton.GetComponent<HoverCheck>().Hovering;
                }

                if (instantiatedButton != null && hovering) 
                { 
                    if (building.GetComponent<BuildingStats>().level < 0) 
                    {   
                        gameObject.GetComponent<Image>().color = instantiatedButton.GetComponent<ColorContainer>().BuildingButtonColor;
                    }   
                    else 
                    {   
                        gameObject.GetComponent<Image>().color = instantiatedButton.GetComponent<ColorContainer>().EmptyButtonColor;
                
                    }
                }
            }```
