then you'd need to detect the planets without using any player direction or global direction

#

you could have eg trigger volumes or a list of planets maybe thonk

#

How does the ground check work? You already have to check if the player is touching a planet, the same method can also tell which planet it is

Hey everyone, I was just wondering if there were any people that had any experience with the experimental Unity Graph Toolkit. Any help at all would be great!

Got something that's driving me absolutely nuts.

    IEnumerator TestCoroutine()
    {
        while (true)
        {
            Debug.Log("Running1");
            yield return new WaitForEndOfFrame();
        }
    }```

If I call this from my monobehaviour's start method, it runs fine. As soon as I call this from another object, it stops after a single loop:

```c#
    public void Flash(int newIterations = 0)
    {
         StartCoroutine(TestCoroutine());
    }
#

Any ideas at all?

keen dew
#

Does the other object get destroyed or disabled

hidden adder
#

No

#

What's more, if I have one instance of the coroutine running from start (runs fine) as soon as I try to run the coroutine again from this other object, both stop

#

I've checked. There's no StopAllCoroutines() or anything similar in play. in theory it should run forever

#

Ah, nvm. I think I've found it. The same event that was causing the external call of the coroutine was also (elsewhere in the code) for less than a frame disabling the gameobject with the coroutine on

#

I didn't pick up on it because it was enabled again immediately afterwards. Silly me!

#

anyone here used Steamworks.NET before? I was wondering if there is a way to get a ping value between player and host somehow, but I'm not doing any actual multiplayer yet, just lobbies

#

chatgpt said that I could technically do a round trip with metadata callbacks, but apparently its unreliable/hacky

#

I'm assuming ping is more for when I have actual multiplayer in place?

#

(like NGO)

wintry quarry
#

Steamworks is just a steam API Library

rancid tinsel
#

so if I wanted to show ping in the lobby, the server would already need to be running at the lobby stage right?

#

any problem with that approach?

#

I like the ping display aesthetically, but it's not that important I guess

hey, quick question, I have to make consumable items (with different rarities) and despite doing some researches I'm still not confident enough to go at it so instead of asking chatgpt, I'd love to have an idea of how you guys would do it. Thanks !!

every project, has requirement with different solutions

tulip vortex
#

well it's a party game with items you can use when it's your turn

#

each has a rarity and an effect

rich adder
rich adder
#

the usual contenders, individual components, Poco (normal classes), Scriptable Objects, or a combination of these

tulip vortex
#

not understanding makes me feel a bit bad

rich adder
#

don't overcomplicate the system, start small and build up.

#

are they timed consumables? do you know how to make a timer? etc.

tulip vortex
#

i was originally thinking about OOP but i feel like this would be a hastle

rich adder
#

I mean everything you do is still OOP.
C# is an oop language

tulip vortex
#

I think i will try to just make a prefab with a linked script

rich adder
#

You mean like polymorphism maybe

tulip vortex
#

well english isn't my native language

#

but smth like this

rich adder
#

You can do like a base Consumable, then each one that inherits it has its own special logic for how it should affect the consumer

tulip vortex
# 

blabla person(name, age)
{
    person.name = name;
    person.age = age;
]
#

I only use that in python 4 years ago so i'm not entirely sure

rich adder
tulip vortex

#

multiplayer is pretty complex, its like relearning everything from scratch

tulip vortex
#

is creating a prefab for each item bad ?

rich adder
#

not necessarily, it really depends how they will be used.. Will they need to be tangible objects in the world or just code that reacts etc.

Ok it's now building, is that the long term fix? May i ask why did it happen in the first place? There is no error in my code

rich adder
#

other than that, it also depends on your Specs, how many assets etc.. Errors in code doesn't affect how long

#

every time you save it has to refresh all the assets

#

some people turn it off and manually do it, really depends . Its a normal part of using this very outdated backend

You can put it on the player if you want, those are details that don't matter much. You're jumping ahead too much

tulip vortex
rich adder
#

Get a item / consumable working first, where you put it doesn't matter.. It can be a component (goes on a object) or just lives in a item manager itself and only through code

tulip vortex
#

I like to have a clear view of the full thing before starting

rich adder
#

understandable, but in most cases if you don't get something going you can't grasp the pros and cons without hitting limits first hand

#

"I did this way but don't like it because of xyz " now you traveled a path that you know you might not take again or use it for a different thing

#

Hello everyone, I have a prefab which contains an image gameobject with image component. I am getting those via the following line : Transform imageTransform = newItem.transform.Find("Image");

Is this just fine or is there a more efficent way to do it?

slender nymph
#

use a serialized field rather than Find

tulip vortex
#

or rather different functions

rich adder
tulip vortex
rich adder
#

if you did
public class ConsumableBase : MonoBehaviour
then HealthConsumable : ConsumableBase
You can use ConsumableBase or HealthConsumable or even MonoBehaviour but you wont get much. use from that

low copper
slender nymph
#

well for starters your prefab will need a component on it to hold that serialized field. then it gets assigned to in the inspector. then instead of using "GameObject" for the prefab type, you use that component so that Instantiate returns the reference to the correct component instead of just a plain GameObject reference.
then it's just a matter of accessing that serialized field (ideally via a property)

polar acorn
tulip vortex

Not currently.

polar acorn
# low copper Not currently.

So you should probably make an Item script, give that script serialized fields for the image and count text, then add it to your prefab, dragging in the things you need into those slots.

Then, you'd change your public GameObject itemPrefab to public Item itemPrefab and spawn in the object with a reference to that script directly. Then you'd just be able to do newItem.image to get its Image child

low copper
#

Ok. That makes sense. But I'm still not sure how newItem.image would be used by the child Image gameobject image component.

slender nymph
#

why would it be "used by the child Image gameobject image component" (whatever that is supposed to mean)? it will contain a reference to that object so that whatever instantiates the prefab can get that reference

rich adder
#

you're linking it there

low copper
polar acorn
low copper
#

Sorry..I'm not using the right terms

#

I think I understand what I need to know now

rich adder
#

You can do

GameObject newItem = Instantiate(itemPrefab, content.transform);
newItem.GetComponentInChildren<Image>().DoStuff; 
``` but that gets very brittle (imagine you want another specific component and 2 of them exist, it will grab the first one not the one you may want)
low copper
#

I'm glad I asked, this is a better approach. Thanks for everyones help help.

#

Yeah..I'm trying to avoid that kind of stuff

#

and optimize as much as I can

#

Ok...this is what I came up with...this is what you guys were suggesting right?

My prefab root object now has InventoryItem script attached to it.

    public class InventoryItem : MonoBehaviour
    {
        public Image image;
        public TextMeshProUGUI count;
    }


 GameObject newItem = Instantiate(itemPrefab, content.transform);
 InventoryData data = itemIndex[item.Key];

 InventoryItem itemScript = newItem.GetComponent<InventoryItem>();
 if (itemScript != null)
 {
     if (itemScript.image != null)
     {
         itemScript.image.sprite = Resources.Load<Sprite>(data.image);
     }

     if (itemScript.count != null)
     {
         itemScript.count.text = item.Value.ToString();
     }
 }
rich adder
slender nymph
#

again, use the type you actually care about for the prefab, not GameObject and you can skip the GetComponent line

low copper
#

Sorry...this is my first time making a prefab. How do I set the prefab as InventoryItem? I tried removing the InventoryScript component on my Item object (see attached screenshot) and it allowed me to but now it is not allowing me to drag/drop the Image + Count object s to the script.

Screenshot_2026-01-26_113352.png
#

Shit..this is the serializedfield thing that boxfriend said isn't it

#

one sec

polar acorn
#

Then, you can make a variable of that script type and drag in the prefab from assets into it

low copper
#

[SerializeField] didn't change anything. It was on the Item object prior

polar acorn
#

You won't need to do GameObject itemPrefab, you can do InventoryItem itemPrefab

low copper
#

Hmm...I tried that a while ago (and now) and visual studio says "Cannot implicitly convert type 'UnityEngine.GameObject' to 'InventoryItem'"

polar acorn
#

Why are you still trying to store it in a GameObject variable

#

Use InventoryItem

#

that's the entire point

rich adder
#

you may need to drag in the prefab again after you change prefab from GameObject to InventoryItem

#

iirc the inspector will say Mismatch type

#

just to be clear, after you put InventoryItem on the prefab there isn't anything else you need to do in the prefab itself, what type you declare for that prefab where you drag it into is what matter

low copper
#

Yep. That totally worked. I am now accessing the variables directly. Hopefully I got it right this time :

 InventoryItem newItem = Instantiate(itemPrefab, content.transform);
 InventoryData data = itemIndex[item.Key];
 if (newItem != null)
 {
     if (String.IsNullOrWhiteSpace(data.image) == false)
     {
         newItem.image.sprite = Resources.Load<Sprite>(data.image);
     }

     if (item.Value != 0)
     {
         newItem.count.text = item.Value.ToString();
     }
 }
naive pawn
#

that == false could just be a !

rich adder
#

also unnecessary if (newItem != null) here

low copper
#

done and done!

Hiii, one question:

I have a sprite, and I config it to be the right proportions, but now im doing an animation for the button and the button was like this: (image1)

So I could put that the expanding anchors (or however its called) are in the middle of the black, but now I have the same size box but like these (image 2):
Its a spritesheet, and each one hast the anchor in the white zone, but that does so that it doesnt appear all the way from the right the white part, instead it appears almost filled instantly.

How can I do that the scale make sense here? Idk if i explained, sorry

Start with YouTube if you want to learn coding. Find yourself a lot of tasks to do depending on your skill level. Do them often. Take lots of notes.

Hey so im trying to make an ability system for my player.
Im unsure of if i should use Scriptable objects or abstract classes
I love the idea of being able to drag and drop abilities into my ability manager and have the behavior change, but im not sure of the best way to run code through scriptable objects.

Meanwhile i could have an abstract class compnet attached to my player for every ability but how would i control them from my ability manager(which handles switching abilities and inputs)

rich adder
#

perhaps if you better state your usecase you might get a better solution

grand snow
#

At that point just add some code or use visual scripting or some custom solution

polar acorn
zealous vault
#

I see. This answers my question. Many thanks.

rich adder
#

you can run functions in SOs just like any other class

#

Unity just makes them Assets / Tangible things in the editor, otherwise they are just like any other classes

vital barn
rich adder
#

that is pretty bad to extend on

#

if you have multiple abilities you're breaking the Finite State concept

#

SOs are pretty decent in most cases if done correct

zealous vault
#

I had a few attempts at state machine NPC enemies outside of Unity, and it didn't work out well. And those enemies were pretty basic.

mint imp
# rich adder the two arent mutually exclusive btw.. SOs can also be abstract

wait wait wait
so im understanding that right

So i make a base "AbilityObject" abstract scriptable object
Then for any ability i make a new "Laserbeam" class that derives from that, so i can inject and overide behavior
Then i guess i would need to create a new asset for it in the editor, drag and drop that into my ability mananer and that would work?

vital barn
mint imp
#

So any new ability would need its own script overideing behavior and a new asset

mint imp
rich adder
# vital barn How

the whole point of Finite state is that you're in 1 state at a time, if you have a invincible ability and flying ability, how would you apply both..

vital barn
rich adder
#

if you want 4-5 abilities active at a time you make multiple statemachines? I don't understand

#

doesn't seem to scale well

vital barn
rich adder
vital barn
rich adder
#

if you can swap them I say making them objects is far easier without having to change the core enum / state
multiple abilities is what I was talking about, if you are using multiple at once how would FSM work there

mint imp
# rich adder You can combine inheritance with SOs without issue the only difference, yes you ...

What if some abilitys are wildly different from each other
From my ability manager i would imagine i just check what ability is in the ability slot, then i call some "Activate()" function
Whatever is in that slot doesnt matter, it will activate

However what if my abilities need refereneces to something on my player, like the location to fire a projectile from
I would think i could pass that through my "Activate(Transform AttackPos)" but that would mean abilities that dont need that would need to pass that information through anyways?

rich adder
swift crag
#

this is a really common problem

#

i tried to tackle this in an RTS I prototyped a while ago

rich adder
#

yeah this isn't exactly an easy task and ultimately you need to experiment

swift crag
rich adder
#

so maybe even a Setup method per ability and they all make their own version to what they need

swift crag
#

You can then ask it for things like "a position" or a "a unit"

#

so, you'd stuff all of the possible targeting data you can into it, then hand it to the ability

#

This means you are responsible for putting the right data in

#

It made it easy to create abilities that can target a unit or a point on the map

rich adder
#

ya like if you have a healing Ability, you have a Use(Target t) etc.

swift crag
#

If you click a unit, the AbilityTarget class has a reference to that unit

#

and it uses that unit's position when you ask for a location

#

if you click the ground, the AbilityTarget just stores a position, and returns that directly

#

You lose some type safety here

#

It's possible to pass an invalid AbilityTarget

#

the ability classes should correctly handle bad target data

#

e.g. by failing to activate or failing to even accept the command in the first place

vital barn
mint imp
swift crag
vital barn
swift crag
#

conceptually, it's not that far off from just doing Activate(Unit targetUnit, Vector3 targetPos, float florp, ...)

#

but you can at least bundle everything into a single AbilityTarget that can provide some kinds of targeting data based on other data

#

(like using a unit's position)

mint imp
mint imp
swift crag
#

The ability could have a ValidTarget method that tells you if it can use the AbilityTarget object you currently have

rich adder
#

You can also further go down the chain like Abilty but also have AbilityType as a enum or maybe just CastAbilityBase etc.

#

the rabbit hole goes deep..

zealous vault
#

Let's say there's a poisoned projectile ability.
There should be logic somewhere dealing poison damage over time.
Well, okay, in this particular case it might be worth coding that into a character, but eventually you'll get a wall of text for status effects Team Fortress 2 has. Won't recommend.

rich adder
#

including the timer

#

the target should never care about how its health is being affected, just that its being affected

swift crag
#

"Effect" systems are another great place to abstract yourself unconscious

swift crag
#

it should know how to take damage

#

it could ask its debuffs to do things

#

like give it a tint color

zealous vault
#

That said, trying to avoid piling up status effects in one place might also be bad design, as you'll then be running around the entire codebase wondering what bug causes damage to be doubled for no apparent reason.

rich adder
#

another reason a FSM may not work for this esp if you have multiple/stackable status effects like
you can be both Poisoned and on Fire

swift crag
#

yes, these aren't mutually exclusive states

#

a finite state machine only makes sense if you can only be in one state at a time

zealous vault
#

I wonder if it'd be a good idea to express would-be state machine states like walking, running, etc as status effects. You don't typically think of "being on fire" and "sprinting" as the same type of concept, but they kinda are.

#

Actually, TF2 already does this for scoping a sniper rifle and revving-up a minigun, which on the user end is a player action and not a status effect in a conventional sense.

Hello, I have been having a real problem with returning projectiles to my pool when the player enters the GameOver state I cant for the life of me get them to just reset without breaking in some fashion.

Its quite a roundabout issue and probably caused by my own spaghetti code because I have a good few functions and classes that interact with or handle projectile logic. I was wondering if anyone would be so kind as to help step through the logic with me as I have been trying to fix this for a week now.

rich adder
#

I typically reset the state when I get it from the pool rather than returning it but not sure if that matter

zealous vault
edgy prism
#

radiant voidBOT
rich adder
swift crag
#

state machines can get really annoying to think about

#

e.g. imagine you can grab an enemy, and the enemy has an ability they can use both when grabbed and not grabbed

#

do you have a separate state for that ability when they're grabbed? do you just have multiple transitions out of the ability state?

edgy prism
# rich adder yeah but not clear wat exactly is breaking or what the issue is > e player enter...

You're right my bad. The first thing I tried was to stop all coroutines running on the projectile, reset it how I normally do (which was working until I added a return all active function) The projectiles would sometimes come back without reset rotations or positions etc.

Then I tried simply turning off any visible elements of the projectile (they come with warnings and indicators) and doing so sometimes the projectile remains active (although invisible) and isnt put back into the pool

swift crag
#

(the latter means you need MANY transitions if there are many situations the ability can be used in)

#

equipping the state machine with a state stack sounds like it'd help – some states would simply pop the stack when they want to end

#

but what if the enemy gets grabbed while using the ability?

How do I make it so, normal color is the testColor, and not transparent?

I'm really confused - what is it upset about here? I'm doing the exact same thing elsewhere

wintry quarry
rancid tinsel
#

oh wait is it the true/false thing

wintry quarry
#

the correct syntax would be:

LobbyManager.OnLobbyJoined += ToggleLobbyUI;```
#

but since it's a System.Action with no parameters,

#

you would need either a lambda here

#

or a wrapper

grand snow
#

(or () => ToggleLobbyUI(true);)

rancid tinsel
#

isn't it impossible to unsubscribe if I use a lambda though?

#

or did I misunderstand that part

grand snow
#

basically yes unless you keep a ref to it

wintry quarry
#

like:

void EnableLobbyUI() {
  ToggleLobbyUI(true);
}

LobbyManager.OnLobbyJoined += EnableLobbyUI;```
wintry quarry
#

you can use a wrapper function like i showed though

#

to make it simple

rancid tinsel
#

wait how do you keep a reference to a lambda?

wintry quarry
#

in a variablke

rancid tinsel
#

I knew that much lol I mean like what type?

wintry quarry
# 
Action myDelegate = () => ToggleLobbyUI(true);```
#

Whatever delegate type the lambda conforms to

#

in this case System.Action is what you want

rancid tinsel
#

I'm honestly way too tired to understand that today I think lol

wintry quarry
#

Delegates are just variables that hold functions. A lambda is just a function you define inline

grand snow
#

when we sub and unsub with a member function its easy
otherwise yea we have to manage keeping a ref to the "anonymous function" used

wintry quarry
#

so a delegate variable can hold any kind of function - a regular one or a lambda

#

and yeah by keeping a reference to it, you basically make it not anonymous anymore

rancid tinsel
#

but I thought Actions are events - how are we storing a function here?

wintry quarry
#

Action is a delegate type

#

They are and always have been variables that store functions

grand snow
#

The event keyword simply adds rules to a delegate type field so it can be used for events

wintry quarry
#

You can use delegates without the event keyword

#

in fact they can do more

grand snow
#

You can but its a bad idea because you can accidently assign instead of += and fuck it

rancid tinsel
grand snow
#

also events can only be invoked in their owning type

wintry quarry
#

it actually takes any existing function in the delegate, "appends" this new function, and stores the collection of all the functions added to it in the delegate

#

so when you do myEvent(); it just calls all the stored functions

#

so yes - events and delegates just store functions to be called later

rancid tinsel
#

ahh ok

#

events really seemed like magic but your explanation makes sense as to how something knows what is subscribed

grand snow
#

Fancy list of functions to call when event goes off

#

c# lambdas make it easy

vital barn
#

Btw delegates (events) can make memory leaks

grand snow
#

Oh yea, an event sub is a reference and thus prevents GC unless both sides can be deleted

#

And if you forget to unsub with something you destroy in unity then that can cause issues

polar acorn
grand snow
#

swift crag
#

subscriber has no reference to the object formerly referenced by publisher

polar acorn
#

Ah, scrolled. Already answered, and better

grand snow
#

yes if we explicitly clear the event/whatever that works too but no point of its owner is going to be destroyed

swift crag
#

now, assuming publisher is kept alive, then the object referenced by subscriber will stay alive too

#

this is less of a memory leak and more of just...an error

#

if subscriber is part of some Unity object and you've destroyed it, you probably do not intend for it publisher to be trying to call it at all

grand snow
#

why cant unity just delete managed objects smh /s

swift crag
#

i used to think it did that

#

we have OBLITERATED your object

Hi, I tried cobbling together a dialogue script for my game and got whatever this mess is. I used to have it so clicking the button to increase the talkcount would have its own switchcase in the talking function, but that seems way too complicated and only works if I want one extra dialogue, another would need another switch case and so on so thats out of the picture. Currently with this snippit of the script that I'm actively trying to work on, the text will always be 'Hey.' no matter what the talkcount is, and when I walk away and come back, clicking the button to increase the talkcount will make it add another number on TOP of that, so at first it adds up in 1s, then 2s, then 3s and so on. This is my first time working with switch cases and dialogue as a whole so I have basically no idea what I'm doing lol, am I missing anything important that I just don't know about?

{

    if (touching && Input.GetKeyDown(KeyCode.E))
    {

        switch (gameObject.name)
        {
            case "kelpy":

                if (talkcount == 0)
                {
                    talktext.text = "Hey.";

                    option1.onClick.AddListener(delegate { talking("I'm done talking to you now.", false); });
                    option1text.text = "Hello!";

                    option2.onClick.AddListener(delegate { goShop(false); });
                    option2text.text = "I wanna shop.";
                }

                else if (talkcount == 1)
                {
                    talktext.text = "worked";
                }

                break;
        }
    }
}

void talking(string message, bool ran)
{
    if (ran == false)
    {
        talkcount += 1;
        ran = true;
    }
}```
rich adder
#

its free and learning it is not complex at all. Comes with its own language which is basically just markdown and can easily do branching

mystic crypt
#

bleurg,,,,,, im using outside resources like that as a last resort

#

id rather learn this myself for future reference

rich adder
#

well start learning basic things like arrays, scriptable objects etc.

#

hardcoding text isn't feasible at all

mystic crypt
#

i know about the toby fox problem where he had the exact same setup and was chastised for it but frankly with the scale of my game i dont see it as a big issue

rich adder
#

ehh with array you can easily switch messages but you do you lol

grand snow
#

It works till you keep adding more and then hate yourself for making it soo hard to maintain and change

mystic crypt
grand snow
#

or others working on it hate you too

rich adder
#

tbh whats the point of asking for opinions if you're going to shut them down because you're fixed on "your way"

mystic crypt
#

my code is already an eyesore for othr people this is just adding onto tje pile lol

grand snow
#

as long as you are aware of the potential issues as it scales then thats good

mystic crypt
#

im taking in ur ideas but like

#

id like to know whats wrong with this right now lol

rich adder
#

yes hence the suggestions of not hard coding things

mystic crypt
#

even if i stop using it its just good knowledge

rich adder
#

you want to have a switch with all the potential people you talk to?

#

wouldn't it just be easier to have each person have their own dialogue / lines

mystic crypt
#

i feel like thatd just be the same problem but with scripts instead

#

unless youre referring to a way of doing that that i just dont know about

#

im assuming you mean a seperate script for each character

rich adder
#

the only thing they would have is their own lines in an array , the script which you interact with dialogue just reads that,

mystic crypt
#

on a coding level

#

not why it doesnt work as in why it isnt feasible

rich adder
#

what do you expect to happen vs what happening now ?

#

like talkcount isn't going up ?

mystic crypt
#

it does, but doesnt effect anything weirdly

#

i think the switch case is like paused somehow

#

also when i move out of the range of the character (resetting basically) it starts going up in 2s rather than 1s

#

then 3s if i do it again

#

its weird

grand snow
#

If comfortable you can use a debugger and see exactly what happens

mystic crypt
#

no idea what that means

rich adder
#

stepping through your code and see where things break down

#

you can also use lots of Debug.Logs but its easier to step through with breakpoints

#

Debugging , is first step identify where the code is going and what the values are

mystic crypt
#

bleuurrg this is a mess ill just use ink

rich adder
#

if its a simple system it might be overkill

#

just rewrite the system to be simpler

mystic crypt
#

i have no idea how to do that lol

#

this is as simple as it gets

rich adder
#

talkcount is good idea and you can combine that with array so index goes up, and line of text changes to something else. If you want you can make it an Object and still link a delagate/action to it (a specific line might want an action to run after it runs/before)

grand snow
# 
List<string> dialog = new(){
"Hello!",
"You suck",
"Bye"};

int dialogIndex = 0;

public string GetAndAdvanceDialog()
{
  string msg = dialog[dialogIndex];
  dialogIndex++;
  if(dialogIndex >= dialog.Count)
  {
    dialogIndex = 0;
  }
  return msg;
}
mystic crypt
rich adder
#

you need basic c# before overtaking a dialogue system tbh

grand snow
#

If you dont know what indexes are you do need to learn some more c#

mystic crypt
#

nooooooooooooooooo id rather burn alive i hate watching tutorials about it

#

im doing fine without even knowing what a class is

#

have been for like 2 years

rich adder
#

dont watch totorials on "how to make dialogue system"

grand snow
#

(X) Doubt

rich adder
#

like the things I suggested before, learn arrays/lists etc.

mystic crypt
#

it is a Game

rich adder
#

those are basics in all systems you make, not just dialogue

mystic crypt
#

just not c# specific stuff

#

or anything too highend

jaunty wing
#

Low level you mean

grand snow
rich adder
mystic crypt
rich adder
#

then robs code should be pretty obvious what its doing

mystic crypt
#

not ? really ?

rich adder
#

literally just going through an array through index

mystic crypt
#

i dont understand what the 'new()' does, or the 'public string getandadvancedialog()' and how those two are linked at all

jaunty wing
#

He could of made it a little bit clearer

rich adder
#

use arrays and lists all the time
doubt

rich adder
mystic crypt
#

im on year 2 of an it college course cmon man 😭

rich adder
#

it creates a new List

#

this is why we suggested basics refresh, this way it looks less scary

jaunty wing
#

But it’s pretty simple

grand snow
mystic crypt
#

oh thats an odd way of doing it

polar acorn
#

And how do you normally write a function?

mystic crypt
polar acorn
jaunty wing
rich adder
#

but this isn't python so this is misleading to say

I use arrays and lists all the time

polar acorn
#

You're kind of going to need to know how to write functions and basic loops

jaunty wing
#

For indexes

grand snow
mystic crypt
grand snow
mystic crypt
#

i just stole this from my code

mystic crypt
polar acorn
#

That's the same keyword

mystic crypt
#

i get that

#

i just didnt recognise it

polar acorn
#

new() is just shorthand since you defined the type already

mystic crypt
#

yeah

#

i see that Now but i just assumed thats how lists are declared in c#

polar acorn
#

Just seeing the word new and knowing how lists normally work should lead you to know what that line is doing.

rich adder
#

You can declare it with new or you can put it later in a function

polar acorn
#

And then the rest of it is pure basics that should fall into place

rich adder
#

important part is know WHY you need new() when you don't for a number for example

polar acorn
#

If you see a thing you don't know, you can try to figure it out from context instead of just stopping reading and assuming you don't know this

grand snow
# 
//Simple way
List<int> myList = new List<int>();
myList.Add(5);

//Shorter way to make a list with some data in it already
List<float> someOtherList = new List<float>(){15.5f};
mystic crypt
#

and i get most of the code in there

#

sorry im a bit overwhelmed with literally everyone talking so i cant say stuff properly lol

#

i literally said i only didnt get the two lines

rich adder
#

Unity throws a curve ball where
[SerializeField] and public do not need =new() and throw a null reference
(serailizing in inspector the engine creates object with new() for you)

mystic crypt
#

of 'new()' which i get now but Didnt because i just assumed lists are declared my way

grand snow
#

Thats good. So in the previous example we made a list with 3 strings inside it already which makes it easier to write and change later.

mystic crypt
#

ive never seen a line like that in my life i dont really have a frame of reference

slender nymph
#

you've never seen a method?

rich adder
jaunty wing
#

Public automatically does what seralizefield does right?

grand snow
#

yeesh

mystic crypt
rich adder
mystic crypt
#

only with voids lol

slender nymph
slender nymph
rich adder
jaunty wing
#

Why would you use serializefield private instead of just public? Does it just expose it for the inspector only?

slender nymph
#

the same reason you would make anything private instead of public. so that other types cannot access it

rich adder
grand snow
#

yea usually we want to serialize a value but not let any old thing fuck with it in code

slender nymph
#

ideally you'd have no public fields

mystic crypt
rich adder
#

you may accidentally change something later on that dont need to be changed

jaunty wing
#

I just write private always, and use public if I need to reference a transform

rich adder
#

public get properties is the way, esp read only

jaunty wing
#

And don’t use seralizefield at all

rich adder
mystic crypt
#

i have no stake in this conversation whatsoever but i just always set my variables as public lol

slender nymph
#

that's bad practice

jaunty wing
#

I mean, it’s not like there can be any security vulnerabilities unless it’s a multiplayer game

rich adder
#

its bad practice, unless you have the memory of a computer

mystic crypt
#

never understood how you could accidentally assign a reference to it and change it

slender nymph
rich adder
slender nymph
#

private vs public has literally nothing at all to do with security

rich adder
#

you can create a bug where you are now changing it through a field where its not meant to instead of a method that may need to run additional logic

vital barn
mystic crypt
#

good attempt

polar acorn
slender nymph
polar acorn
jaunty wing
#

I mean, you can call public methods but you can’t call private methods

#

That’s what I mean

grand snow
# 
//For anyone to look at
public IReadOnlyList<Stuff> CurrentStuff => stuff;

//Just for meeee
private List<Stuff> stuff = new();
rich adder
# mystic crypt you lost me

Imagine you have a public MoveSpeed variable, and everytime you change it a Sound should be playing..
so you create a method that takes in a number and pass it to your movespeed, along with that it plays a sound in that method..

You later want to change moveSpeed from somewhere else through the field only.. suddenly your sound stopped working and you wonder why its "bugged".
(and forgot due to time, work amount etc. that it has a method you made for it to change)

mystic crypt
#

im already drained from the last conversation these are just words being thrown at me at this pojnt

rich adder
#

we dont know fire burns until we touch it and realize it.. so you may still need that

rich adder
grand snow

why would it?

a very long time ago lol

so it first iterates all of them in the current loop

and then destroys them in the next frame - is that right?

what does the documentation for Destroy say about that?

well that's what I got from it

the objects are destroyed at the end of the frame, not the next frame

FINALLY okay after installing 12 billion things I got it to work

I was asking about this earlier and found a solution but have a new issue...
So im using abstract Scriptable objects for the abilities my player uses.
I like the drag & drop functionality. Its working well for my single player who would ever use them.
For the sake of wanting to use this code for other projects in the future i tried to allow my enemies to use these abiliities as well.
Everything works except a quite predictable outcome that Scriptable objects are static So if 2 enemies try to use the "laser beam" abiltiy at once it acts weird, because i store a "currentLaserPrefab" in the Scriptable object itself.
I understand the issue but im not sure what do about it.
I guess i would need another script to contain data like that per character that might use it but it defeats the purpose of drag and drop abilities.
Any thoughts?

wintry quarry
#

What does currentLaserPrefab mean though? The prefab for the laser changes at some point?

mint imp
wintry quarry
#

sorry that variable name confused me

#

Shouldn't it be currentLaserInstance?

#

prefabs are the things that live in the asset folder, not in the scene

youre 100% right ofc
its just my bad naming convention

ill change it

But basically. I'm not sure exactly how your game/code works but I would probably structure it something like this:

public abstract class WeaponSO : ScriptableObject {
  public GameObject projectilePrefab;
}

public class Laser : WeaponSO {
  // whatever specific laser stuff
}

public class Player : MonoBehaviour {
  public WeaponSO equippedWeapon;
  public GameObject weaponProjectileInstance;

  void Shoot() {
    weaponProjectileInstance = Instantiate(equippedWeapon.projectilePrefab);
  }
}```
#

This way weaponProjectileInstance lives on the MonoBehaviour for the individual player

#

it's not stored on the ScriptableObject

I am not getting the behavior of the paddle ball to work. It goes straight up into the air, but I want it to go in any direction and when it collides with a collider, whether it is me or a block it bounces again like a normal ball. Where did I go wrong here?:

        if (playerController.ShootBall==true)
        {
            // Calculate the impact point relative to the paddle's center (-1 at bottom, 1 at top)
            float hitPoint = (transform.position.y - collider.transform.position.y) / collider.bounds.size.y;

            Vector3 newDirection = new Vector3(Mathf.Sign(ballRb.linearVelocity.x) * -1, hitPoint).normalized;
            acceleration++;
            ballRb.linearVelocity = ballRb.linearVelocity.normalized * (initialSpeed + acceleration);
          
        }
        
    }

this is on the ball script

#

when I press space the ball fly to hit an object and bounce from said object like the one in paddle game

#

but now it goes straight up as if it is a flying rocket

is there an int version of mathf.pingpong repeat ?

#

any scenario where it give the undesired output when cast (int) on float?

naive pawn
#

it's truncation

tranquil forge
#

will 1.9999 became 1 then

#

also is there an int version of mathf.pingpong repeat ?

naive pawn
#

PingPong seems to be just a triangle wave, so you could make an integral lerp for that

#

Repeat is just modulus/remainder

is there a proper way to set an images color? i made some WHITE sprites in aesprite and i set it up like this:
i import the image and turn off compression and set the filter mode to point (no filter)
i create an image in the heirarchy under the canvas (as usual) and i set the sprite to that WHITE image.
during runtime, i set the color like this

imageVar.color = Color.white;

and while the image is still there, you cant see it anymore. it makes me think of that one time a long time ago an image file i had corrupted somehow and while i knew it was still on my drive i would never get to open it again because the file is corrupted.

why are you using fixeddeltatime in update
-# in response to a deleted message

#

does this sun have any other components, eg a rigidbody?

naive pawn
hybrid tapir
#

my AI Claude said that the multiplication is the reason why pure white was the best option. didnt stop unity from screwing me over still.

naive pawn
#

yikes, ok

hybrid tapir
#

in aesprite i made sure it was pure white

naive pawn
#

that's.. probably not related

hybrid tapir
#

yea cuz if it was mixing in a black pixel id still get a color

naive pawn
#

without more info i'd guess it's probably rendering orders

hybrid tapir
#

setting it to any color makes it dissapear

naive pawn
#

what if you set it from the inspector

wintry quarry
hybrid tapir
#

it took me hours to make my own image of a ps5 controller and then break it down into parts

#

i did it pixel by pixel

#

and also used the bucket ofc

#

i was thinking that unity made a new dumb modern way of doing it with code but kept it secret so much that even claude doesnt know about it

naive pawn
#

ok maybe stop relying on AI

rocky whale
#

have you tried doing it with the color structure

naive pawn
#

Color.white is using the Color struct

hybrid tapir
#

oh yea also setting it in the inspector during runtime works fine. and yes i was using the color struct

#

im in unity 6.3

naive pawn
#

show the inspector from when it disappears

hybrid tapir
#

literally i got everything else working fine but for some reason i still cant set a color with code.

#

any unity version i use has this problem

wintry quarry
#

so whatever object this is will be invisible

#

you can tell because of the black bar at the bottom

#

My guess is you have a bug in your code setting the alpha to 0

#

if you need help finding it - feel free to share your code here

#

Same thing for all the colors in your video

hybrid tapir
#

what is a colors alpha? i had no idea that was even a thing.

#

next time im on ill also set the alpha to max

#

in the code

wintry quarry
#

(alpha)

#

alpha is transparency

#

0 means fully transparent

wintry quarry
hybrid tapir
#

cuz all i do is set the Color to Color.white.

wintry quarry
#

I'm guessing you're doing something else as well that you forgot about

hybrid tapir
#

maybe there was a setting in Aseprite i wouldnt have thought to look for.

#

ill ask my friend whos a pro with that app as well tomorrow

wintry quarry
#

this isn't an aseprite issue

#

this is the color on the Unity Image component being set to alpha 0

#

Aseprite would have nothing to do with it

hybrid tapir
#

oh

Hey, I know this isn't technically for beginners, but i'm a beginner, could someone help me create a friction system in my game?
For now, the game is very basic. I already have some movement with AddForce, but I really need to add friction. Also, I already have a system to detect if my character is on the ground, which is necessary for the friction system, if I'm not mistaken.

I've tested it a little, but I have to admit, I find that it makes everything seem rather archaic.
I think I'll try to do mine anyway. I don't know if you'd be okay with continuing to help me. I don't want to be too much trouble.

#

The little game I'm planning is really based 90% on movement gameplay, so I really want to get my hands on it.

The Ultimate Guide for Physics in Game Development!

In this video, I am going to thoroughly go over everything about physics in game development. Regardless of whether you are a complete beginner and don’t know what a force is, or a seasoned game developer who uses physics all the time, I can almost guarantee that you will take something new away from this video. This is the ultimate guide for ...

is anyone able to explain why when im unloading my old scene the canvas is like half rendered for a split second?

#

you can see what i mean in the video

#

my setup is just a overlay canvas in my main menu scene

#

and then im switching to a scene which just has a overlay canvas

#

no scenes have any cameras since its an overlay canvas

#

ignore the scene switching for now i discovered its happening here as well

#

"Interface" is my canvas and i added a image gameobject to it covering the rest of the ui

#

and i made a script which simply sets the game object not active

#

im on unity 6.3 lts

it is disabled

its also a fresh project

im making a even fresher one on 6.3

this is unity 6.3 fresh project

#

this is half way through disabling the image object

#

wait unity 6.3 has vsync turned off by default let me check if it helps

#

it was screen tearing

tender stag

but idk how to fix it without having vsync on

i tried limiting the fps to the refresh rate and it didnt help

# sage hedge Hey, I know this isn't technically for beginners, but i'm a beginner, could some...

few things

  1. friction with other solid objects and with the air already exist. Its the physics material and drag setting respectively
  2. you really shouldn’t use either, or AddForce for a platformer unless you want a particular physics-y (and kinda janky) feel. You are much better off just setting the velocity directly. “Friction” is usually implemented by gradually lerping the X component of the velocity to 0 when no movement is pressed. You can have this happen faster or slower in the air, but thats just a modifier on it

Thank you, that's very clear.
In addition, I've done quite a bit of research since earlier, and I've understood a few principles, if only in how to use C#. Yes, I'm that much of a beginner.

queen adder

!code

radiant voidBOT
queen adder
# 
void Update()
{
    Vector2 verticalInput = moveActionReference.action.ReadValue<Vector2>();
    Vector3 finalInput = verticalInput * (movementSpeed * Time.deltaTime);
    transform.Translate(finalInput);
}

void Update()
{
    Vector2 verticalInput = moveActionReference.action.ReadValue<Vector2>();
    Vector3 finalInput = new Vector3(verticalInput.x, verticalInput.y) * (movementSpeed * Time.deltaTime);
    transform.Translate(finalInput);
}
#

which input and movement makes more sense?

eternal needle
queen adder
eternal needle
queen adder
#

like do i need to create a new Vector every cycle in the bottom solution or the first solution is the better one which updates the same one i think?

eternal needle
#

This is extremely negligible though

queen adder
#

Ooh okaym, so either way Its creating a new Vector3? I didnt know that

eternal needle
#

U could create 10000 vectors every update and probably see no performance difference

queen adder
#

the conversion happens in the first solution right, the second one creates a fresh new one

eternal needle
queen adder
#

And I didnt quite understand which one is doing more operations since im converting to a vector3 before multiplying like you said

naive pawn
naive pawn
queen adder
#

yeah I got that thank you, but I dont get what bawsi said about converting to a vector3 before multiplying, so its multiplying all 3 values. Thats what I didnt get, how is it converting before multiplying?

#

so this line creates a new Vector3

# 
new Vector3(verticalInput.x, verticalInput.y)
#

and then multiplies

# 
* (movementSpeed * Time.deltaTime);
#

where does the conversion happen first?

naive pawn
queen adder
#

I dont understand 🙁

naive pawn
#

which part exactly?

queen adder
#

in the first one I have a vector 2 input which is used to create the vector3 final input variable, which has three floats no?

naive pawn
#

do you understand the difference between these 2

Vector2 original = /* ... */;
Vector3 a = ((Vector3)original) * 2;
Vector3 a = (Vector3)(original * 2);
naive pawn
queen adder
naive pawn
naive pawn
queen adder
naive pawn
#

what's the result of original * 2;

#

the type, i mean

queen adder
#

what do you mean what type?

#

I dont know what is original

naive pawn
queen adder
#

the result is a Vector2 still

#

so the difference is that first its converting to a vector3 then multiplying by two and the second solution is multiplying Vector2 by 2 then converting to a Vector3?

naive pawn
queen adder
# 
void Update()
{
    Vector2 verticalInput = moveActionReference.action.ReadValue<Vector2();
    Vector3 finalInput = new Vector3(verticalInput.x, verticalInput.y)(movementSpeed * Time.deltaTime);
    transform.Translate(finalInput);
}
naive pawn
#

so that just doesn't make sense

queen adder
#

so this code referes to ```cs
cs

# 
Vector2 original = /* ... */;
Vector3 a = ((Vector3)original) * 2;
#

its the same right

naive pawn
#

it's not valid, you can't call a Vector3

queen adder
#

what do you mean? its compiling and working

naive pawn
#

are you perhaps missing a * in that snippet

queen adder
# 
    void Update()
    {
        Vector2 verticalInput = moveActionReference.action.ReadValue<Vector2>();
        Vector3 finalInput = new Vector3(verticalInput.x, verticalInput.y) * (movementSpeed * Time.deltaTime);
        transform.Translate(finalInput);
    }
naive pawn
#

right, that's converting to Vector3 and then multiplying

queen adder
#

so here the conversion happens first and then multiplication with movement and deltatime?

#

okay so now how does verticalInput multiply three times here

#

if its only ```
cs

#

dammit

# 
verticalInput.x, verticalInput.y
#

if its only this, how is it three times

naive pawn
#

it's a Vector3

#

there's a z value

queen adder
#

or it multiplies that z value too

naive pawn
#

yes

queen adder
#

okay so it does it by itself automatically we just dont have to type it out

naive pawn
#

it's not "automatic", this is a function that unity devs have written explicitly

queen adder
#

okay so vertical input multiplies with three values x y and z converts to vector3 then multiplies with movement speed and deltatime

naive pawn
queen adder
naive pawn
#

the 3 multiplications were from when you multiply by movementspeed*deltatime

queen adder
#

ooh

naive pawn
#

there's no multiplication happening in the conversion itself

queen adder
#

so I just get a vector 3 by assigning the vector2 values and a z value of 0 then multiplying all three values of that vector3 with mvoementspeed and deltatime

#

finally i got that, okay now how does the first solution have only two multiplications

naive pawn
#

because it's multiplying a vector2

queen adder
# 
void Update()
{
    Vector2 verticalInput = moveActionReference.action.ReadValue<Vector2>();
    Vector3 finalInput = verticalInput * (movementSpeed * Time.deltaTime);
    transform.Translate(finalInput);
}
#

okay so this is multiplying that vector2 with movementspeed and deltatime and unity is converting it to a vector 3

naive pawn
#

c# is doing the conversion, not unity

#

unity specifies how to do the conversion, and that the conversion is possible

queen adder
#

understood, so its easier to write and on a microscopic level better to write like this?

naive pawn
#

technically yes

#

at this scale, the benefits of being easier to read/write/maintain far outweigh the increased speed of 0.000001%

queen adder
#

yeah reading and writing is def easier this way, thank you for your patience and explanations, truly appreciate it.

#

since im learning I want to understand why and how code works, not just blindly writing out syntax

naive pawn
#

if you want to get into the nitty gritty details i'd recommend learning C, it really helps understanding all the underlying concepts for various syntactic sugars like this

#

(or even asm, depending on the level of detail you're interested in)

queen adder
#

learning C as in just the syntax? Or youre recommending to get into lower level stuff?

naive pawn
#

the details of how stuff works at the fundamental level, and then you can kinda see how syntactic sugar maps onto that

queen adder
#

this is already hard enough for me as is, I think getting even lower would be just too difficult to grasp, English isnt my first language too, makes it harder to learn on top

naive pawn
#

but yeah like i mentioned this is kinda really deep details already

queen adder
#

i thought reading a book about game math

eternal needle
# queen adder i thought reading a book about game math

there honestly isnt that much to learn about it unless there's a specific feature you want to implement. the only thing here was the difference of when a vector2 was converted into a vector3. In one case, you manually created a new vector3 before multiplication happened. In the 2nd case you did multiplication then converted it to a vector3
If you're trying to learn vector math, it doesn't have to be in a game context because it's still just math at the end

#

oops I wrote it backwards, in the first case you did the multiplication first then converted. In the 2nd you created the vector3 then multiplied

queen adder
#

tried making a third person camera rotating around the player with zoom and it was hell, I did manage to make it work but I would be lying if I said I made it myself, I just used what I found online and glued everything together. Quaternions are hell for me so im starting from basics in 2D space again

naive pawn
#

quaternions are hell to everyone tbh

#

just treat them like a black box and only do the public operations

void bluff
naive pawn
#

!code

radiant voidBOT
naive pawn
#

would help to post your code appropriately ^

#

it's also not super clear what it's supposed to be. this door is supposed to be a portal, right? where's the exit?

queen adder
#

@naive pawn I have another solution could you maybe give your input

# 
Vector2 verticalInput = moveActionReference.action.ReadValue<Vector2>();
transform.Translate(verticalInput * (movementSpeed * Time.deltaTime));
#

this seems to work as well

#

is it the same as my previous solution, but the calculation happens in the Translate parameter?

# 
Vector2 verticalInput = moveActionReference.action.ReadValue<Vector2>();
Vector3 finalInput = verticalInput * (movementSpeed * Time.deltaTime);
transform.Translate(finalInput);
#

the compiler will generate the same thing, the upper solution might be easier too since I dont have to create a separate Vector3 but maybe would be harder to use if more logic would be involved in the future?

#

is my thinking right?

rich adder
#

solution 2 is always cleaner

#

if needed to debug it, you can easily pass it to another function. Like Debug.Log without touching anything else

queen adder
#

so generally its better to keep the calculations out of class methods and just use the final variables inside of the parameters correct?

rich adder
#

its not a hard rule. Imo mainly for clarity and such, I say it is

queen adder
#

okay makes sense to me too

#

same thing here where I can just calculate the direction towards the player like this

# 
Quaternion lookRotation = Quaternion.LookRotation(playerTarget.transform.position - transform.position).normalized;
#

but its better to do it like this

# 
Vector3 direction = (playerTarget.transform.position - transform.position).normalized;

Quaternion lookRotation = Quaternion.LookRotation(direction);
