that would be a good option too

eternal needle
#

Or just do similar logic in awake, because this happening 3 times isnt gonna do shit to your performance. Although its not pretty

#

doing it in OnValidate isn't a great idea here. I doubt itll matter for your performance either but this shouldn't be something that constantly needs to run

real thunder
#

it's happening like 10 times but for sake of doing less I guess I ll leave it there

#

ll put in Awake for now

#

half questions I ask here is I am realizing I made a poor design this game so I gather some info how to make next game better

naive pawn
#

relatable

eternal needle
#

Yea the better design here is just spawning them at runtime via code, you'll avoid scenarios where an existing object in a scene is outdated because you never went back to update it after updating the prefab. Or maybe im misremembering how that works but Im pretty sure that'll be an issue in your current setup

real thunder
#

it's somehow fairly easy to make something which works but to make it look like something I don't want to cringe looking at is harder

naive pawn
real thunder
naive pawn
#

this one's also an option btw, i find it helps with linking singletons or whatever

eternal needle
naive pawn
real thunder
#

additive scene sound like... bad for performance? but I don't really know how it works

naive pawn
#

that's the point of prefabs

naive pawn
eternal needle
#

Something about this sounds wrong, but idk I could be thinking of something else

real thunder
eternal needle
real thunder
#

I suppose that would be a scriptable object with alot of info and a script overriding stuff using it

naive pawn
eternal needle
#

I see, yea not sure what I was thinking of then. Maybe unpacked prefabs which obv wouldnt work

#

It's been too long

eternal needle
#

Can't really compare the performance either because you'd be using it in different ways. Like if you have the same pause screen UI exist in every scene, that's being instantiated everytime you load the scene
If you load it additively, it's not tied to your gameplay scenes anymore

real thunder
#

I don't understand the attitude of caring about pefromance only when it starts lagging

naive pawn
#

computers are faster than you think

#

unless you absolutely know it's going to be a problem, or it already is a problem, don't worry about optimization - you have better things to worry about.

#

compilers are really good at optimization, too.

real thunder
#

I guess the right way to put it would be to say if it's not big performance hit it's not worth caring about

naive pawn
#

yeah

real thunder
#

but like u can do alot of nasty stuff without causing lags

#

but why would you

naive pawn
#

and a lot of the time, that nasty stuff is bad for other reasons, too

#

Find is fragile

#

i can't think of other examples off the top of my head

#

doing GetComponent for every access reduces maintainability and readability

#

don't worry about perf unless a) you start having perf issues, b) you are working in the millions of iterations, or c) you are working with extremely limited hardware, like an arduino or an NES

real thunder
#

I had ALOT of tolerable overhead by overusing navigation api for example

naive pawn
#

but yeah anyways in many cases, preemptively/prematurely optimizing for perf can reduce readability or maintainability, for relatively little gain

real thunder
#

many raycast checks and stuff I have got cooldown timers but they could as well not have it

fair cedar
#

what is a good way to find what gameobject is closest to a specific other gameobject?

public AggressionTarget RequestTargetClosest(AggressionTarget requester, Vector3 where_from_seek)
    {
        if(targets == null)
        {
            Debug.Log("No valid targets");
            return null;

                if (targets[i].is_visible_to_attackers && IsValidTarget(requester.team, targets[i].team))
                {
                    float distance_to_target_square = Vector3.SqrMagnitude(targets[i].coords - where_from_seek);
                    if(distance_to_target_square < shortest_distance_square)
                    {
                        candidate = targets[i];
                        shortest_distance_square = distance_to_target_square;
                    }
                }
            }
        }
        //Debug.Log(requester.target_position + " attacking " + candidate.target_position);
        return candidate;
    }

I use that

#

I was going to ask about this method

#

on profiler I see how the most expensive things are apparently... getting transforms positions?

naive pawn
#

perhaps keep a set of those viable targets for this purpose

real thunder
#

would that make more sense to maintain a list of Vector3-correspondingTransform structs each frame

fair cedar
#

oh okay i am using tags but i didnt know how, but i think i just found the method Distance() bcs i am lazy to do it from scratch

real thunder
#

so in the long run if same frame I get many requests each would only iterate once

naive pawn
real thunder
#

oh well yeah targets[i].coords is a property for getting transform position

naive pawn
#

well, it's 2 method calls that crosses into and out of native code, so i would expect it be at least a significant chunk of this method, i guess.

but it being "most expensive" doesn't really mean anything. is it expensive enough to be an issue?

#

how many targets do you have, and how much cpu time is it taking?

real thunder
#

for now it's not an issue but I want to see how hard I could push it

#

I remember till I added cooldowns it was on 1-2 place on CPU time with like... dozen of ms or something?

#

along most frames

naive pawn
#

dozen of ms? i don't think that's right

grand snow
#

me thinks this isnt beginner stuff too

real thunder
#

as for the amount it's tens for now and at this game and hundreds in my dreams

#

I suspect I would have to go to the different architecture

#

I forgot how does that Unity package called

#

non OOP components

naive pawn
#

ecs?

real thunder
#

yes

naive pawn
#

anyways i don't really think this is gonna be an issue at hundreds

verbal dome
real thunder
#

just editor with profiler

#

deep profile

#

not deep won't even show methods right?

verbal dome
#

Deep profile exaggerates the cost of small method calls a lot

real thunder
#

🤔

sour fulcrum
#

🤔

verbal dome
#

(Also if you profile editor you should try standalone profiler, though might not matter here)

Nah just waking up xd

#

in his defense i have misspelled a word so bad i just typed a different word while i was completely awake XD

real thunder
#

oh also it's not the question of this channel but why when I increase Minimum Region Area I get more tiny navmeshes

#

but not the other way around

#

no wait it... looks random

#

I just want one big navmesh

#

it keep baking me tiny ones too even if I type in absurd 9999999999999999999999999 in min region area

#

cool Unity docs saying "Note: some regions may not get removed"

teal viper
#

Minimum region area wouldn't merge separate navmesh regions.

#

It decides if an area is being enough to have a navmesh or not.

real thunder
#

I know

#

by I just want one big navmesh I mean I want everything else culled away

#

sounds trivial enough but unachivable without fiddling with colliders manually it seems

naive pawn
real thunder
#

I don't think there will be a solution anyway

radiant frigate
#

hi guys

#

I'm new

random sigil
#

guys does void means function?

real thunder
#

you should learn basics of C# somewhere

#

to answer the question it means it does not return anything

random sigil
#

im learning it and i want to understand not just copy do you have a source to learn from? likeyoutube channel or smthng

real thunder
grand snow
real thunder
#

it's kinda hard to learn by just learning Microsoft docs or something because to to know what is A you need to know B and to know what does B you need to know A kind of thing

#

on second thought not really but it feels like it

random sigil
#

is InvokeRepeating a good way to repeat voids instead of timers?

#

yeah i hate docs 2 pages for 1 information

real thunder
#

it's a thing which works but ugh

#

it's annoying to debug

#

not ideal for performance

grand snow
#

And you have less control so id avoid it

random sigil
#

ok then how to repeat with ease

real thunder
#

...timer

#

or coroutine if you wish

#

but it's also less control

random sigil
#

is there a built in timer like godot? i hate doing timers

sour fulcrum
#

coroutines are the closest

real thunder
#

timer at Update is the most annoying but most manageable

real thunder
sour fulcrum
#

you can stop coroutines?

real thunder
#

you may also forget to disable coroutine

random sigil
night fable
#

How to acces the store

sour fulcrum
#

online, but not a code related question

real thunder
naive pawn
#

yes you can do that

random sigil
#

and a lot of variables for 1 timer not worth it

naive pawn
#

it's 3 variables

sour fulcrum
#

if you need many variables to do something then you need them

real thunder
naive pawn
#

"can you communicate without communicating" no, obviously

#

but you would need that in Update regardless

sour fulcrum
naive pawn
#

most stuff you can put in Update, you can also put in a coroutine, they run on the same cycle

random sigil
real thunder
#

for oneshot things I d go coroutine

#

for something bit complex I am not sure it's worth it

naive pawn
#

you need 1 thing for configuration and 2 things for tracking state kinda regardless of how you do it
using InvokeRepeating just hides the latter ones away - you don't have to manage it, but you also can't manage it. both a pro and a con.

random sigil
#

hold up bro its my first day in cs

real thunder
#

yeah coroutine and invoke have timers internally

naive pawn
random sigil
#

im getting rage baited

naive pawn
#

the variables end up being locals rather than class members

real thunder
naive pawn
#

not what i said, no

#

coroutines can both use built-in timers or your own timers

sour fulcrum
#

they don't have timers, you can use a timer with them

random sigil
#

guys i have a question : how does cs script act in unity like every script its for 1 object or i can use it in another

real thunder
sour fulcrum
#

a component is a instance'd version of your script that many be on many objects

#

1 script

x "live" versions of that script

naive pawn
#

the component is a version of the class that can be run by unity, the class is a blueprint for the component/instance

grand snow
#

Sounds like learning about object oriented programming will help!

random sigil
#

atwhatcost let me read again

naive pawn
random sigil
#

like the class is a blueprint i can chnage on it for every object i put the script in?

sour fulcrum
#

@random sigil have you played minecraft

random sigil
naive pawn
#

you can't change the blueprint for each object, no

#

oh man, very interested to see where this analogy is going lmao

sour fulcrum
#

your script is like, how a grass block is defined in the code

a component/instance is a grass block placed in your world

random sigil
naive pawn
#

it has the same instructions, but each object can have different values set that result in different behaviors

sour fulcrum
#

you might make a skeleton script

then you would spawn instances of the skeleton at night time

random sigil
#

ok like if i created a spawning script and put it in zombie creeper and skeleton they will spawn if they can and spawn in the time i put in thier metadata or smthng

sour fulcrum
#

there's a couple things off there in a literal sense but vibe wise your on the right path i think

naive pawn
#

sure, and you could have 2 instances of the spawning script where one is set to spawn chickens at daytime and one is set to spawn zombies at night.
same script, different inputs, they can act differently using the same instructions

random sigil
#

like the object will act on hes act like if the code contain color changing the object will chaneg it color if he had a color and if he can

sour fulcrum
#

like if a wikipedia page was a .cs script, it might look something like this

image.png
#

thats your script

#

then this crafting table would have 3 instance's of your Cobblestone script

image.png
#

because they are three different "objects" that all come from the same script

random sigil
#

ok i understand know

sour fulcrum
#

most of programming has very direct comparisons to minecraft

random sigil
#

like the breaking script will act on the hardness for the block and if the pickaxe can break it , like something liek that

naive pawn
#

well, minecraft is a program lol

real thunder
#

especially with OpenComputers mod

sour fulcrum
random sigil
#

and every block

sour fulcrum
#

yup

random sigil
sour fulcrum
#

there's abit more to it for that (called inheretence) but thats a little more advanced then what we are talking about

naive pawn
#

also composition - in reality there probably wouldn't be a class for each block, you would have a class for all blocks, then each specific block would be a "scriptable object" that holds the data for each block, like the infobox batby sent above

#

(that's also outside the scope of what we were talking about though. this will come up much later)

random sigil
#

i saw a video that said the class is like a factory and the functions are the machines is that a right concept because i understand this concept

sour fulcrum
#

that is right but also like

#

the scale of that comparison isn't always 1:1 with reality

#

eg. if your making a printer (like something that prints paper), that would probably be a class, not a function

#

but it might contain functions like

Scan()

Print()

Copy()

Refill()

etc.

random sigil
#

oh

#

i understnad that too

#

the printer is a factory

sour fulcrum
#

yess

random sigil
#

the printer have a scan machine print machine etc

#

oh its easy now

#

when i first heared of classes i thought like a real class

sour fulcrum
#

thats fair lol

#

but also if you were programming a school that would probably be right 😛

sour fulcrum
red ivy
#

how is it with multiple nav mesh agents on one nav mesh surface? It doesnt work for me

naive pawn
rough granite
sour fulcrum
rough granite
# sour fulcrum

More lines of code in this one file than i've written in the last 2 years 😔

naive pawn
#

also terraria is closed-source so if this is from a decompilation it's probably marked up or done in a more sensible way in the source code, but that's just a guess

rough granite
# sour fulcrum

Surely they arent insane enough to write these by hand, and instead have a helper script to write it for them

naive pawn
#

compiler optimizations be wilding sometimes

sour fulcrum
#

im pretty sure it is like this

naive pawn
#

how can you be sure though

sour fulcrum
#

i dont have a direct source so take it how you want but used to do modding stuff and im pretty sure one of the devs confirmed it

naive pawn
#

huh, interesting

sour fulcrum
#

i know for a fact one of them told me they don't have any documentation

#

like for design stuff either

naive pawn
#

i mean, undertale and balatro have similar things (and are kinda well-known for it)

#

so i wouldn't doubt it

real thunder
#

my AI code is close to 9k lines

#

where base class is like 3k and chilrend are like 1-2k

#

it works but I feel like

#

I made a grave mistake

#

so the structure is
I got a bunch of Action s for SFM
where without any incapsulation it's just alot of methods
SomeStateStart
SomeStateLoop
{
SomeStateCheckEmergencyExit
ActualCode
SomeStateCheckNormalExit
}
SomeStateCheckEmergencyExit
SomeStateCheckNormalExit

#

I am not sure what to do about it

#

I need some kind of FSM I guess

#

I thought of making it like at FEAR maybe

autumn verge
#

i have a project using the muip library to do some animation effects like sway on hover over etc

real thunder
#

where it's a list with priorities

#

I gonna ask

#

I want to make an architecture where I can easily add and remove states

#

where like I can ugh

#

...yeah I should think for some time to figure out what exactly I need and then go from there

sage mirage
#

Helelo, guys! By the way, I found a way to create my own PLayerPrefs.SetBool() XD. I mean why Unity doesn't have PlayerPrefs.SetBool in the API and its really interesting.

    {
        PlayerPrefs.SetInt(key, value ? 1 : 0);
    }``` thats how we do it right ? I mean it was so hard to write these lines of code?
#

Becuase i am trying to save some values and was searching for SetBool().

frosty hound
#

A bool is just a number, so there's no need to have it otherwise.

real thunder
#

main issue is imagine I have a system of 9 states and then I add 10th one
and now I have to manually specify transition into 10th state and transitions from that state to all other states

wintry quarry
#

Was it really "so hard" to write?

frosty hound
#

Same amount of lines = so hard to write. 😬

#

I guess if we're nitpicking based on character count, you might be breaking a sweat, yeah.

autumn verge
#

how does sway work?

#

this project i'm on uses the muip library to implement icon sway on hover over

#

the bug is that in a partuclar mode

#

the sway is too much

frosty hound
#

Are you asking how sway works or how to change the intensity of it in a specific library that you're using?

autumn verge
#

both

frosty hound
#

What does sway mean in this context? The icon just rocks back and forth/up and down on hover? It would just be using a simple Mathf.Sin to oscillate it back and forth.

autumn verge
#

yeah

#

right now the behavior in one mode is that the icon just flies away

#

but in the other mode the sway is fine

#

and i'm unsure what property to look for that's different

frosty hound
#

I don't know this library so who knows

#

Maybe it's a scaling thing, is the bad scaled larger? Could be that it's multiplying the effect?

#

Or it could be that it's restarting the effect each time and it's just going off in one continual direction

autumn verge
#

it seems to be scaled the same?

#

when you have sway

#

how does the rect transform play into that?

frosty hound
#

It shouldn't do much, other than moving the position of it

vernal vortex
#

Hi, if I want to pass through a variable as a reference in an Action, what is the syntax for it? I tried Action<ref type> but it says invalid token

slender nymph
#

you'd have to use a custom delegate for that. but what are you trying to pass as reference, and why? that seems like it would be a bad idea

naive pawn
#

can you not just use a mutable reference type

autumn verge
#

i'm working on another issue

#

the thing is to literally move lights so that they're on top another asset

#

but i do the copy and paste and it doesn't work. the light's dont appear on the new asset

light glacier
#

does unity allow interface method implementation bodies?

slender nymph
#

yes

grand snow
light glacier
#

Yes I mean default implementations. I heard c# allows it. Struggling right now implementing it.

naive pawn
#

and probably provide some more context as to what exactly you're doing, not sure what you mean by "on top another asset"

grand snow
#

e.g. FooBar.InterfaceThing() wont work but IInterface.InterfaceThing() does

sour fulcrum
#

and ofc (FooBar as Interface).InterfaceThing) can be used to do that but a little cursed

light glacier
grand snow
#

basically stop trying to use it like multi inheritance

light glacier
grand snow
#

it sucks but this is not what this feature is meant for

grand snow
sour fulcrum
grand snow
#

best to not do this overall and fix your design

naive pawn
#

huh so you can't practically (ab)use this for multiinheritance the way you could with java's version

sour fulcrum
#

some of the newer c# stuff lets you get a little more weird with it

#

also i think with generic extensions you can get it down to just this.InterfaceThing()

#

doesnt save the cast but looks slightly cleaner kinda

light glacier
#

I don't have that much experience with default interface method implementations but it sounds better than starting inheritance. guess in my case i might just do a static?

sour fulcrum
#

no just start inheritance

naive pawn
#

we don't know what your case is

#

but most likely you can just do normal OOP stuff

shell sorrel
#

if you are making large interfaces with lots of default implementations you are likly reaching for the wrong tool

#

if its a small 1 or 2 method thing then sure makes sense

rich adder
#

did OP explain usecase here? I feel like something is missing..

light glacier
#

one sec

shell sorrel
#

also why the need to cast to call it?, just implement them publically

light glacier
#

its a small one. I'm creating something that will need multiple UI Controllers and each of them controls which Screen (VisualElement here) is visible and which are not. So I want to make sure each of those controllers will have the same functionality and implement methods that can't be implemented via default method

#

Reason I need multiple UI Controllers is that I will have multiple scenes which are almost isolated from the actual game

#

and since i will need to implement multiple ui controllers i want to make sure each implements the same functionality. But 1 method can have a default implementation since it will be the same for all ui controllers.

shell sorrel
#

so thing is with default interface implementations is they can only access what is exposed in the interface its self

#

depending on how this is structured maybe a abstract class as the base might be more correct

rich adder
#

I suppose you could combine interface with abstract class

light glacier
#

yea i was thinking that too. abstract classes and interfaces with all those extra features kinda start blending together

rich adder
# 
public interface IUIController{
    void ShowScreen(string screenName);
    void HideAllScreens();
}
...
public abstract class UIControllerBase : MonoBehaviour, IUIController
{
  public virtual void ShowScreen(string screenName){
etc..```
light glacier
#

thanks! I'll check what I will do

shell sorrel
#

also i feel if something is named IUIController really it a class not a interface

light glacier
#

yea think i remember usually its class = what it is and interface = what it can do

rich adder
#

hmm yea you can probably just do this with the abstract class since unrelated items have no reason to implement interface anyway

shell sorrel
#

yeah more a is a vs can do

#

most of my interfaces tend to end in able so like IDamageable for example and often are very small quite often only 1 method

cosmic dagger
#

IDamageable, IHealable, IInteractable, IRuntimeDamageModifier (hmmm, screwed the pooch on that one) . . .

shell sorrel
#

i have often used it for modifers as well

#

but sometimes i just do that with just basic named delegate types instead

cosmic dagger
#

oh, i haven't done the named delegate types. i heard it's good for intellisense bcuz you can actually what's it's for . . .

shell sorrel
#

yeah can help signatures docement themselfs more vs seeing a Func<T1, TR>

cerulean sigil
#

heya! does anyone know how I can pass in an IEnumerator into a dictionary? right now I get this error with this code:
public Dictionary<HitboxType, IEnumerator<>> funcs = new Dictionary<HitboxType, IEnumerator<>>();
I also did try passing in IEnumerator as ..., IEnumerator> funcs... but that still caused an error

image.png
naive pawn
#

what's this for exactly? if you're storing coroutines you can also just store the Coroutine itself (but also seems like a weird thing to store in this way in general)

cosmic dagger
#

you didn't provide the type for the IEnumerator . . .

cerulean sigil
naive pawn
#

and all the coroutines would be active at the same time?

#

would you not want to start the coroutines later?

#

gotta mentally separate the method that defines the coroutine, vs a coroutine that's actually running

cerulean sigil
#

ahh okay thank you, im very new to c# so is there a different way you would recommend to do what im trying to do instead of this?

naive pawn
#

you could store the methods that define the coroutines

#

would be like, Func<IEnumerator> i think

#

(your coroutines should be using plain IEnumerator and not the generic one, as i've found)

swift crag
#

yeah, that's what Unity is expecting anyway

#

IEnumerator<> by itself isn't a valid type; it's something you can construct a valid type from

#

(you do see this notation occasionally, but it's uncommon)

Hello! I am currently trying to view a decompiled cuphead project but when I try viewing it it unity it says 'unexpected symbol 'ref' ' , looking at the code, due to my lack of C# knowledge, I can't seem to find anything wrong & the stuff I've seen is talking about C# methods & all that fancy-pancy stuff but I just want to get these errors fixed so I can compile it

image.png
teal viper
shell sorrel
#

its a reference variable, iirc not all C# versions support it, also yeah we don't talk about modding and decompilation here

teal viper
#

Oh, didn't know that was valid C#. What version was it added in?

shell sorrel
#

they only work local to the function, but more or less lets do some pointery stuff with value types

teal viper
#

Interesting

shell sorrel
#

i do not think i have ever used the feature

#

almost always a other way that is more readable to others

Hi everyone, if you can help me with this code, the car moves forward and everything, it has the handbrake, the normal brake that makes it move forward, go in both directions and everything, right? But when it moves forward, there's a kind of delay if I release the key that makes it move forward or backward, and also the rear wheels spin as soon as I press the button instead of moving as the wheel colliders are moving. Almost part of the code was done by an AI, those two errors were done by the AI, but it made it worse than it already was.

https://paste.ofcode.org/dtLH6ZZmGMeLFFv78U2KD7

teal viper
#

Regarding delay, the issue could be with the input or the way velocity is accumulated. You can investigate both with debug logs or debugger breakpoints.

teal viper

I've no clue what you're trying to ask.

yeah, it's super rare to see it, but unbounded generics can be used in some places. like the typeof operator, and nameof in c# 14. i wanna say i've seen it in asp.net as well? maybe with dependency injection or something, but it's been a while since i used that

Any idea why limiting FPS stopped working for all my projects?
I'm running Unity 6000.10f1, but was not coding for a while. Yet I updated unity for all projects in the meantime due to the security issue they had.
I checked other projects and they also ignore the FPS limit of 60 now and instead use VSYNC at 144 Hz.
Also, if using vSyncCount = 2, it still uses 1x.
Also, if using vSyncCount = 0, and target frame rate -1, it still uses 1x VSYNC, ignoring my code entirely.
But I can see Unity recompiles when I change the settings.
I did not change my code at all.

Might want to explain how you're verifying this, what platform you're compiling to and if it's VR or whatnot.

Oh. Never mind. Problem between chair and keyboard. It's a great idea to actually use that script in a game object
if you wanna have it do anything. Where is my coffee mug?
Me only copied the code from an existing project and forgot to assign it. Sorry. notlikethis
It works not in the actual build, but Player still caps at 144. Weird, but can work with that.

I'm trying to change emission source position for particle system thru code but i can't figure out how to access it's transform.
I tried using "ParticleSystem.shape.postion =" but it says that ".shape" is read only. I tried using "ParticleSystem.transform.position" but it moves object instead of just particle emiter.
Any tips for how to set particle system emission source position properly (thru code and not editor)?

typically you want to keep a prefab for the argument for Instantiate, and then receive an instance of that prefab as the return value

#

these 2 things should be kept separate

flint oasis
#

so ive got an issue with one of my scripts where i want to make it fire in bursts (i got that part down) but i want to make sure i can start another burst while one is already active. how would i fix that?

sour fulcrum
#

you haven’t described something that is broken

#

we would need to see code and know what you don’t understand

swift crag
flint oasis
naive pawn
#

have a variable to store the state that you're currently burst firing, then check for that being false before you fire a new one

#

would recommend using coroutines over invoke here, so you can have the logic flow contained in a single method, just gives you more control

#

you wouldn't need eg bulletsFired to persist across method calls, it'd just be a local inside the coroutine method

flint oasis
#

so like this

image.png
naive pawn
#

no, that immediately sets firingBurst back to false

#

InvokeRepeating just says to call that thing later, the code after still runs immediately

flint oasis
#

i think this works better?

image.png
naive pawn
#

could just have firingBurst = true in the "fire bullet" part, and also you could use !firingBurst instead of firingBurst == false, but yeah, tryitandsee

#

i'd recommend looking into coroutines though.

#

also, seems like you'd keep firing the burst fire even if you run out of ammo, is that intended?

#

it'd go into the negatives lol

flint oasis
#

no i didnt even notice that

naive pawn
#

also note that this would also wait before firing the first bullet in the burst

#

if that's not intended, well, there would be multiple workarounds each with drawbacks, but the proper solution would just be to use coroutines or similar lol

flint oasis
#

i have no idea what those are

naive pawn
#

they're basically a tool to manage doing work over multiple frames, they make waiting and such easier to read and write by keeping stuff together in a single method rather than being scattered into class members

Hi! Im very new to Unity and was going to add Animation Layers to my Player Character, however when doing a quick test it ended up messing up the ground check and making the character extremely floaty
I didnt know where else to put this but some help would be greatly appreciated!

#

So I've been trying to tinker with my player's attack animation and noticed that some frames of animation won't appear on screen sometimes. Like my character's active hitbox is about 3 frames but when I slow down footage. It would be 2 frames of active hitboxes instead of three. Its inconsistent and Im not sure on what could be some potential causes for this

#

Anyone have potential ideas as to why?

Its 2D sprites in unity 3d so idk if theres something Im not really do properly

You see the unity inspector is trash by default so you don't without add-ons like editor attributes (free) or Odin inspector

I quit working on AI for a month to just stall with doing architecture work (Which has mostly dried up now). Its been 1 day and Im already drowning. Do professional developers in this situation just hire a specialized AI dev or what.

rich adder
prisma shard
#

Industry people who get hired solely for AI jobs?

rich adder
#

can your budget permit hiring someone -> yes -> hire someone
no-> simplify the implementation / scale down the requirements

prisma shard
#

Part of me feels this AI stuff is just so hard that I find it hard to believe people here are just chilling through it

#

and i also dont think u guys are hiring people so

shell sorrel
#

define what you mean by AI, its a pretty overloaded term in game dev

prisma shard
#

Like u have 500 units roaming around in a section of the map. And then have to path 60 people through it while not losing any fps

rich adder
#

I think they mean like NPC not gen AI thats abused

shell sorrel
#

it really depends on the type of game, the path finding part there are multiple ways to do it, but how its handled for large groups like in a RTS game differs alot from a regular A* on a navmesh

rich adder
prisma shard
shell sorrel
#

the behaviour of the NPCs really depends on your game, but the pathfinding part generally you can shove that off to its own thread

prisma shard
shell sorrel
#

well how you approach literally everything in your game changes based on if you need total determinism or not

prisma shard
shell sorrel
#

not just stuff like this

rich adder
#

multithread is great of offsettings calculations so you don't bog down the main thread for other stuff

prisma shard
prisma shard
shell sorrel
#

yeah for example at my old job, yeah it took a few frames from a NPC to calculate its path, but it did not matter much since people would not notice that delay and it does not hold the game up since pathfinding had its own thread

rich adder
#

put the proper checks to avoid hitting the same objects at the same time to avoid race conditions

prisma shard
rich adder
#

when you say determinism I think more of something like physics, where at least I think Entities / Unity Physics provide things like determinism in that case

shell sorrel
#

A* and stuff like that does not care what dataset it operates on, it just needs a node (that is a convex space) and its neighbours

rich adder
#

Would be so cool if unity would've actually provide a standalone A* component

shell sorrel
#

last time i wrote my own, the part doing the work could be applied to grids, a bsp or just a navmesh and worked

rich adder
#

we have NavMesh which is essentially A*. They should've abstracted that into seperate component so you can also use it on grids / 2D

shell sorrel
#

the navmesh built in is good enough for most cases especially if 3d

#

its mostly only a problem for something like a rts game

rich adder
#

yeah true , the navmesh agent. Another different story but there are workarounds

shell sorrel
#

last job i built my own soultion used for the whole org, but it was due to fitting the needs of the type of game they make

#

current job i am just using the builtin stuff since what is needed is way less specialized

rich adder
#

I used free version but Aaron bergs A* pathfinding project has some decent stuff too. I bet by now its highly optimized compared to when I tried it last 4 years ago

solar hill
#

Yeah i think that one comes with 2d nav meshes

#

or rather an equivalent

rich adder
solar hill
#

i kinda hate how the free version is just an older version though

#

like i dont mind having less features on the free version

shell sorrel
#

even for 2d something that is a octtree or navmesh can work better then a grid, results in way less nodes

solar hill
#

but at least it could be kept up to date for some other issues

mint imp
#

Not sure if this is beginner but
Im working on the system to save my game, its already working.
I have a shop where you can buy items, currently the items available are filled in inspector with a list<Item> (Item is a scriptable object)
but im trying to think of the best way to save that data. Also to save which items have been bought already.
I was thinking a Dictionary<Item, bool> ?
but i wanted to ask other ways people accomplish this?

rich adder
shell sorrel
#

you will notice in something like a RTS game everything flys at the same height from ground

#

since they more or less just used a 2nd grid of mesh for the sky

rich adder
#

if they are in collection, they are bought

rich adder
shell sorrel
rich adder
#

pushed navmesh to its limits xD

#

at first I had an "air" base platform navmesh would navigate then use raycast to shift the mesh/collider up and down while keeping nav agent glued on mesh, it was not pretty lol

shell sorrel
#

but yeah either way to the OP, this is all stuff that can be learned, just might take a week or 2 of a deep dive to understand it then start building. But i would first lean on established things like the built in system or the pathfinding project if they suit your needs

#

i found creating good NPC behaviour that feels good for your game and doing good steering and stuff was harder then the pathfinding aspects of things

mint imp
rich adder
#

basically You don't need to compare an enitre Object, an ID should suffice

# 
foreach (ShopItem item in shopItems){
bool owned = IsPurchased(item.itemID);
    if (owned){
        Debug.Log($"{item.itemName} is already owned");
        // buyButton.interactable = false;
        // ownedText.SetActive(true);
etc.
    }```

agile turtle

can somebody help me to fix this problem

naive pawn
#

what's the issue you're referring to here exactly

agile turtle
#

I used a box collider to check if it was on the ground, and then it malfunctioned like this: the jumps were jerky, and when I entered another section of the track, it got stuck.

naive pawn
#

why do you have both a capsule collider and a box collider

agile turtle
#

capsule for climbing

#

box to check ground

naive pawn
#

yeah no i shouldve been clearer. why are they both non-trigger colliders

agile turtle
#

here is my script

naive pawn
#

it seems like half the issue could be that your tilemap is not using a composite collider

#

do you have a composite collider on your tilemap

agile turtle
#

yes

naive pawn

and the tilemap collider is set to use the composite?

#

Sanity check here, is there anything that can suppress an OnDIsable call?

#

I keep getting NREs from events that I should have safely unsubscribed from

#

in the OnDisable class

#

seems to happen on scene switching

grand snow
#

But only other thing I can think of is its virtual and overwritten

tardy mist
devout otter
grand snow
#

Cinemachine can handle the camera movement to follow the player for you so you can just worry about the player movement

stuck palm
#

I've made sure to call base

#

on overwritten methods

grand snow
#

but tell me this, why OnDisable?

#

do you actually disable this and need it to unsub then be able to resub on re enable?

stuck palm
stuck palm
#

so when I leave a scene, then come back

grand snow
stuck palm
#

there are missing things

grand snow
#

Then i re direct you to my question again and ask if you actually need to do this on enable/disable?

#

sounds like no

#

I always do Awake/Start + OnDestroy myself

#

Or Init() + OnDestroy

naive pawn
grand snow
#

ops that was a mistake, i mean Awake + On Destroy

#

@stuck palm tl;dr swap to Awake/Start/Init + OnDestroy if you dont actually need this to happen on object enable/disable state change.

stuck palm
#

there are some instances where onenable / disable is required , such as a settings menu that is enabled and disabled but for others it makes sense to use the other

#

such as scene swaps

grand snow
#

hmm does it really? does this settings menu exist always?

#

but you know better than we do what your stuff needs

stuck palm
#

does not persist

#

what actually is the difference between awake and start? they both only call once right?

grand snow
#

And then hopefully realise the difference

stuck palm
#

so it's only called before onenable??

#

but I see that awake is the very beginning and on destroy is the very end

grand snow
#

Meaning awake and on destroy inform you of creation and destruction once as they should

stuck palm
#

yeah I think this fits what I need better

#

for the errors I'm getting

naive pawn
#

so basically, whenever its isActiveAndEnabled state changes, which requires it to be enabled, and its gameobject and all parents to be active - if any of these become false, that triggers OnDisable, and once all of them become true, that's OnEnable

#

also note that Awake for scene objects also requires the GO to be activeInHierachy, so an object may never have Awake called if it's never active before it gets destroyed

hey guys so ive been really frustrated with trying to even get my player to move right and i genuinely want to know how to even learn this thing. cuz every tutorial i watched uses a different system and i have no idea which one to even use angerjoy i might be stuck in tutorial/course hell so id really really appreciate if someone gave tips or something on learning this. i did 2 courses on unity learn (roll a ball and haunted house) so i tried referencing the script for my own player movement. but i genuinely dont know how to add jumping like call me a dumbahh but ive been stuck on this for 3 hours 😭🙏

#

this is the original script that i took from the haunted house course, and the one that i tried modifying. i kept trying to add a jump MoveAction based on the original script but i kept getting errors. like if anyone could just point me in the right direction or resources id be so so thankful. sadok

is there any way to use get and set accessors on a ScriptableObject?

such as:


public class SomeClass : ScriptableObject
{
    [SerializeField] public float MyVariable
    {
        get {...}
        set {...}
    }
}```
slender nymph
#

you can use properties on a scriptable object just fine. but you can't serialize them directly, you can only serialize their backing fields

naive pawn
cosmic dagger
#

My answer is their two answers . . .

muted sand
# 
[field: SerializeField] public float MyVariable
    {
        get { ... }
        set { ... }
    }

if i do this i get a CS0657 warning

slender nymph
#

that only works for auto properties. if it has an explicit backing field then just serialize that

naive pawn
#

oh you actually have custom accessors?

muted sand
#

yes

naive pawn
#

serialize the backing field you have instead then

#

value inside accessors isn't supported in unity yet, right?

muted sand
#

it is

#

i think atleast

slender nymph
cosmic dagger
#

It is . . .

muted sand
#

right?

muted sand
naive pawn
muted sand
naive pawn
#

value is the input value for setters, but field refers to an automatic backing field and that one isn't serialized, did i get that right?

slender nymph
naive pawn
muted sand
#

okay

#

got it

# 
public float MyVariable
{
    get { ... }
    set { ... }
}

[SerializeField] private float my_variable;

so I can use this yes?

Hello ! Again, i have question about the the Raycast system.
So, basically, i want the A point to touch the C point no matter what, and return :

  • False if there is a wall (In the layer : LevelTiles)
  • True is there is no wall

Here's the code : https://pastebin.fr/019e3732-88d3-728b-a6b9-f376b40b0ef1
with the main line being if (!Physics.Raycast(PositionA, positionB, 20f, excludedMask))

But for some reason, it appear that the player is always seen...
The "LayerMask" only contain le Layer LevelTiles, and the wall is on that layer...
Am i doing things the wrong way ? If someone can help me, i would be glad. Thanks ! :)

naive pawn

anyways, yeah check the signatures of the stuff you're using

Raycast does not take 2 positions - it takes a position and a direction

errant breach

Well, thanks for giving me some explications. It surprise me tho because it does work when i give two positions, am i doing something wrong ?
And alright, i'll check..

naive pawn

just being the right type is not enough, it also needs to be semantically correct - points and directions and etc all mean different things and have different meaningful operations.

Ok I tried that code and I couldn't get it to work.

I tried using this code and it just made me rotate to the right (positive of the y axis) slowly no matter the speed I gave it. Is it maybe because I locked the camera or am using play mode in the engine?

 [Header("Settings")]
    public float LookSpeed = 1.0f; // How fast the object rotates (default: 1)
    void Update()
    {
                 // Get mouse deltas via Input.GetAxis()
        float mouseX = Input.GetAxis("Mouse X");     // Horizontal movement
        float mouseY = Input.GetAxis("Mouse Y");    // Vertical movement
        
        // Rotate around the Y-axis (left/right) and Z-axis (up/down)
        transform.Rotate(Vector3.right * mouseX * LookSpeed * Time.deltaTime);
        
        // Hidden just in case I wanna try it
        // transform.Rotate(Vector3.up * mouseY * LookSpeed * Time.deltaTime);
    }
keen dew
#

Debug.DrawLine has different parameters than the raycast

errant breach
naive pawn

lines and rays are different semantically! rays have an origin and direction (and maybe a length), lines have an origin and an endpoint

you have a position, you need a direction

    void Update() {
        float h = horizontalSpeed * Input.GetAxis("Mouse X");
        float v = verticalSpeed * Input.GetAxis("Mouse Y");
        transform.Rotate(v, h, 0);

I set the vertical speed to 0, and it turns left and right. but its delayed with my mouse and kinda iffy

Oh I thought the vid was send here I guess its too big

I'll see if I can compress it rq

errant breach
# naive pawn you can get the direction by subtracting 2 positions

Thanks ! I now do
direction = PositionA - positionB;
And i've changed :
if (!Physics.Raycast(PositionA, PositionB, 20f, excludedMask))
to
if (Physics.Raycast(PositionA, direction, 20f, excludedMask))

use something built for URP if thats what you're using or you'd have to make your own in splines sure, that can get quite complex depends wat you're doing

instead of trying to force some hacky solution that nobody would enjoy, why not address the underlying problem

#

bit of a weird vibe

pliant dome
#

Relax and thats up to me to decide whether I want to do that for my game

#

If you don't want to help thats fine but no need to get so aggressive about what is a bad decision for my game

#

Sorry for not providing enough context

grand snow
#

You would need to alter the timescale all the time based on the current framerate as modern engines are designed to NOT have this flaw

#

your own logic can do this easier but yea its not a desirable thing hence it being weird to use this as a solution...

slender nymph
#

it's literally introducing a different problem that makes the experience worse to solve some thing you won't even describe because you're dead set on this bad solution

pliant dome
grand snow
#

what is the actual problem anyway

pliant dome
#

Ill try to describe best I can

#

If the game fps slows down from 60 to 59 or anything lower. The animation of the 2d sprite would tend to skip or extend certain frames to keep it consistent with the game fps. Which would be fine in most cases but since Im making a fighting game. If a player animation gets extended this could result in the active frames of an attack to be extended

#

or it could skip a frame and make the active frames of when an attack could hit shorter

slender nymph
#

is your animator using unscaled delta time?

pliant dome
#

and my thought process was that if the fps was tied to game speed, when the fps drops. The framedata of attacks stay consistent

grand snow
#

If framerate is capped and advancement of this simulation uses frames then that would produce the result you want

#

but things like the animator and anything else needs to be fudged with timescale changes

pliant dome
#

Sorry but can youclarify what you mean by that

grand snow
#

e.g. your own animation system that you "tick" forward using Update()

pliant dome
#

Oh the sample rate?

grand snow
#

if you animate and advance this game state yourself then easy

#

e.g.

float duration = 1.5f;
float time = 0f;
const float FrameCap = 60f;
const float FrameTime = 1f/FrameCap;

void Update()
{
  time += FrameTime * (FrameTime / Time.deltaTime);
}
pliant dome
#

So I use a state machine. WOuld I basically put this inside each state script for each animation?

grand snow
#

if designed badly i guess but lets hope not

#

a better design would have a singular update with a custom delta that is then used to update everything pertaining some object

pliant dome
#

pertaining some object? Like as in this doesnt affect everything in the scene but per object?

grand snow
pliant dome
#

Okay thank you

grand snow
pliant dome
#

The statemachine that calls each state is running through Update(). Would I not be able to do this?

grand snow
#

Okay, unity handles calling Update on our scripts for us. So my recommendation is your own manager to do this but instead provide the custom delta
Or you need to re calculate this everywhere/inherit from a type that does this for you

pliant dome
#

Ohhh okay lemme try something then. I think I can do that

grand snow
#

at this point do what you can manage but try to make use of shared constants for the important values like the framecap

round scaffold
#

I wondered a little bit ago but I want to find the closest enemy to an object using overlapSphere, alot of forums use stuff like using the sqrMagnitude of the distance and all that
but i wondered if it would be more optimal to just increase the size of the hitbox over time and return the first thing it hits, is it more expensive to constantly change the hitbox data of a sphere or to just use some distance math in a preallocated list

#

not in a sort of conundrum about optimization I was just curious lol

naive pawn
#

checking distance gets the closest by pivot of each object
checking with physics gets the closest by collider bounds

#

though note that the physics thing alone won't guarantee getting a unique result anyways

#

bottom line is, consider how exactly you want it to behave. i did say the physics thing would be more expensive but if you're not doing overly tiny increments then it probably won't be super significant

Hey guys, I am new to Unity 3D and was having some trouble with cinemachine settings, I would really appreciate it if someone could help me out.
Basically I wanted to know if there is a way to set cinemachine freelook camera an equal distance away from the player no matter where the player is looking? (Screenshot is what I want to avoid, I want the player character, in this case the capsule in the center of the rings)

round scaffold
#

the freelook camera has always been kinda wonky to use imo i usually just use a regular cinemachine camera attach it to an object on the players head and rotate that object via mouse inputs

pure cypress
round scaffold
#

its gonna require some extra coding but it will be better since youll have better control of the camera anyways and dont gotta deal with the freelook cameras wierd numbers lol

round scaffold
#

but i think it would cause problems later down the line anyways if it hits 2 objects at the same time or sum

#

wonder if its possible to make hitbox detection without relying on unity physics engine and probably having some unessesary calculations not go thru

Basically, I have a mouse hover sound effect on my UI buttons and when the sound effect / SFX Mixer Channel reaches -80dB for one reason at the end I hear frequencies that are annoying for the player experience, so if I do hover many times and the sound effect will play 5 times lets say I hear this disturbing frequencies at the end, when it reaches -80dB.

But what I want it to do is on event to set the dB to -79.9 basically

#

Let me show you my scriopt

Yea unity does not provide a way to modify any channel specifically apart from the exposed params

no idea why its so black box but hey ho

using UnityEngine.EventSystems;

public class UIButtonAudioEvent : MonoBehaviour, IPointerEnterHandler, IPointerClickHandler

        audioManager = ServiceManager.GetService<AudioManager>();
        settingsManager = ServiceManager.GetService<SettingsManager>();
    }

    public void OnPointerEnter(PointerEventData eventData)
    {
        audioManager.PlaySFX(SFXType.Hover);
    }

    public void OnPointerClick(PointerEventData eventData)
    {
        audioManager.PlaySFX(SFXType.Click);
    }
}

  {
      float masterVolume = masterVolumeSlider.value;
      float dB;

      if (masterVolume <= 0.0001)
          dB = -80f;
      else
          dB = Mathf.Log10(masterVolume) * 20f;

      audioMixer.SetFloat(MASTER_VOL, dB);
      PlayerPrefs.SetFloat(MASTER_VOL_KEY, masterVolume);
      uiEvents.RaiseUpdateSliderValue(masterVolumeSlider, uiManager.MasterVolumeText);
  }```
So here I have my settings manager and UIButtonAudioEvent class.
#

but slider has nothing to do with it I dont know why I send it XD

grand snow
#

im confused what the issue actually is

sage mirage
#

oh sorry

grand snow
#

if you dont want it to go below a value then clamp/correct the slider min

sage mirage
#

my bad yes you are right I can do it with exposed parameters with an out value I thought there isn't a method to GetFloat and there was only to SetFloat

grand snow
#

Oh right yes if you want to read back the current value then yes.
However if you always control the value set you shouldnt need to

sage mirage
#

because I cant really remember what the out keyword does?

#

it is a way to return more than 1 values from a function?

polar acorn
slender nymph
#

if you do need to return multiple related things from one method call you typically would want a struct containing that data though. the out keyword shouldn't really be used as a replacement for returning related data

polar acorn
#

It is most useful in cases where you want your function to return a "status", and if that status is that the function failed, the out parameter isn't ever used anyway. This is how it's used in things like TryParse or TryGetComponent

#

They don't want all their data at once, but a sort of two-tiered system where the out only matters if the return is something specific

Hey guys I'm using Unity InputActionMap and have a question, I have a PlayerInput.cs, and IControllables, and was wondering If its possible to do something like ```c#

public interface IControllable
{
InputActionMap inputActions { get; }

Vector2 OnMove();
Vector2 OnLook();

void OnKeyPressed();

}

private IControllable controllable;

foreach (var action in inputActionMap)
{
action.performed += controllable[action];
}``` The general idea is just naming all my map actions the same as the function they should be activating in IControllable

#

This is PSEUDO code btw, not functional, just to get the general idea across

ivory bobcat
slender nymph
upbeat pasture
slender nymph
#

either way you're still going to be getting the relevant method groups manually somehow. i'm just saying that you can put it all into a single method that is implemented directly in the interface

#

then you aren't duplicating the code anywhere and it isn't a mess of trying to determine what action was passed to it and which method is relevant to that action

upbeat pasture
#

I think im overcomplicating this, I could probanly just pass the InputObject lol

slender nymph
#

yes, unity supports default interface methods which you can do here. or you can use some static method in some static class that handles it (that would require passing both the interface instance and the action map)

grand snow
#

interfaces can include events in their definition but no idea if default implementation works here

slender nymph
#

the interface wouldn't need the event, they would just be subscribing to the existing events on the action map passed to a default method

upbeat pasture
grand snow
#

oh right just bridging from event -> some instances

slender nymph
#

basically just this:

public interface IControls
{
  void OnSomeInput();

  void SubscribeInput(InputActionMap map)
  {
    map.FindAction("SomeInput").performed += OnSomeInput;
    //etc
  }
}

How to address cinemachine freelook through code?

Or how to toggle between two different cinemachine cameras?

polar acorn

If both cameras have the same priority, whichever one was enabled most recently will take focus, so you could just enable the camera you want to switch to

And then disable it when you're done with it, and it'll go back to the old one

hey everyone, just want to say thanks in advance just in case i can't get back asap. but i do have one question;
Does anyone know of any good alternatives on the ''pity'' randomizer?
I'm looking for a solution that:

  • after 'x' amount of rolls, this item has been selected ''at least once''.

important! *specifically not saying this:

  • after ''x'' amount of rolls, all items have been selected ''at least once''.
#

i also need this to be true for all individual items

frosty hound
#

Alternatives to what?

acoustic sequoia
# frosty hound Alternatives to what?

a Pity System. it's a system that takes psuedo random and tries to make it 'feel' more fair for looting items.

becasue in a loot pool a rare item might have a 4% chance to appear. but it's possible for you to roll 200 times and still never see it even though that situation has approximatly an average of being picked twice.

the idea of a pity system is to make that rare item always be obtainable after '200' amount of rolls.

lethal meadow
#

takes psuedo random what?

#

numbers?

acoustic sequoia
# lethal meadow numbers?

anytime you use a random number, it's always pseudo random. which i'm assuming you already knew, so i'm confused by what you are asking

lethal meadow
#

"it's a system that takes psuedo random and tries to make it 'feel' more fair for looting items"

acoustic sequoia
lethal meadow
#

pseudo random is used to describe something

#

it isnt something

acoustic sequoia

# naive pawn bags?

i specifically don;t want to use bags because that means every item is picked exactly x amount of times after n rolls... i want their to be a randomness to it but exclude the super unfortunate cases..

naive pawn
#

you can randomize the bags

#

the bags don't have to be fixed

#

this only works if you only have 1 of these constraints though (or the constraints are all for the same x)

and it doesn't have the same "gets more likely with more misses" that typical pity systems have (at least i think they have? i don't have much experience with these systems)

acoustic sequoia
# naive pawn you can randomize the bags

i understand this.. but let me give you an example with numbers:

say i have 5 unique items. all with a 20% chance of being picked.

i create a bag that is twice it's size and every unique item is placed in the bag twice.

then it's shuffled.

the problem is if the first two rolls are (i.e.) item 1, then i can expect to never see that item again for at least 8 more rolls. <- this is predictable

naive pawn
#

and the constraint here is that each item needs to appear at least once in 10 rolls?

#

i mentioned randomizing the bags specifically to reduce this predictability

acoustic sequoia
naive pawn
#

ok so you said both yes and no lmao

acoustic sequoia
naive pawn
#

so in this case, you could have a bag of 10 elements where 5 are fixed, and the other 5 are randomized from that original 20% distribution

acoustic sequoia
#

i can clearify that there is a difference in what i am saying

acoustic sequoia
naive pawn
acoustic sequoia
#

oh right, i was trying to figure out why i didn't want to do it this way.. and it's because i don't want to preconstruct a seeded bag..

naive pawn
#

how come?

#

(also disclaimer - this is just my spur-of-the-moment idea, idk if it's been used in real scenarios, there may be caveats that i haven't thought of)

acoustic sequoia
# naive pawn how come?

because it iterferes with some of my other systems..
what i came up with in my head is something to do with individual item percentages that fluctuate when they have reached a maximum misses.

naive pawn
#

isn't that what the pity system does

acoustic sequoia
lethal meadow
#

what you were describing is a function to bias the probability to make it more common over time

#

or just to give you the item after a fixed amount of tries

naive pawn
acoustic sequoia
lethal meadow
#

that is what i just said yes

acoustic sequoia
acoustic sequoia
#

so i need to garentee that every rare item is rolled at least once after 30 rolls for example.

#

without using a bag system

naive pawn
#

yeah pretty sure you just need a bag for that

#

otherwise you'd need a really convoluted system basically to emulate a bag

ivory bobcat
#

so i need [..] every [...] item [...] once after 30 rolls
So it's just a normal random system?

acoustic sequoia
naive pawn
#

no, just make a bag

#

very low max rolls and very similarly-sized pool, just make a bag for this, man

acoustic sequoia
naive pawn
#

75 is still very low max rolls

#

isn't pity used for stuff in the thousands of rolls lmao

acoustic sequoia
#

the problem isn't the size of the bags it's the time between rolls.

naive pawn
#

that isn't an issue

#

subnautica uses bags for its ore loottables

#

3200 extra bytes for a save file all things considered is not that much

acoustic sequoia
# naive pawn subnautica uses bags for its ore loottables

so respectfully lol my game is not subnotica. and it's a very unique kind of game that is similar to an idler game mixed with rpg elements. but most of the game is waiting around. specifically on a major time scale similar to real life. one of the fundamental pillars of the game is actually closing the game and coming back tomorrow to see whats happened. it plays itself offfline.

#

i didn't say your game was subnautica

or in subnautica as mentioned previously, there's a drop chance for each item, but using a bag so it guarantees you don't get unlucky and get starved for a specific resource

Hey guys, I tried making a 3D boss fight game.

don't worry. take your time, and break down each line. the biggest thing that helped me is typing everything line-by-line, word-for-word, and looking up every term along the way.

public int curHealth;``` i would make sure i understand what `public` is and does. what is an `int`; why use that? then why we're calling it `curHealth` and not just `health`

`public` is an access modifier that specifies how much access (or how visible) the field is to the rest of you code (other types). there are other access modifiers like `private`, etc. `public`, specifically, allows access to all of your objects or types

`int` is a value type that stores signed whole numbers

`curHealth` is the name of the `int` field. we're using it to represent the current health of an object.
------------------------------------------------------------
it's a simple example, but if you do this for every method, calculation, and assignment, you'll understand what each line is doing and why . . .
