[fast briar]

One of my properties already have a Base Class which is MonoBehavior.

[tropic lake]

yeah so that's an issue there

you can have the class inherit from the base, and the base inherit from mono
or you can use an interface

[fast briar]

I can try to transfer that property into one of the classes Ive made.

No dice, it has fields that requires the properties on the other base class.

[fast briar]

There we go, something like this.

[tropic lake]

cool

[fast briar]

So declaring the properties like this, I may be missing something, and how can I get the property CalculateCollectedStars() which is in the actual MonoBehaviour parent?

[fresh salmon]

Properties need a name, just like your filename field

You currently have access_mod type;, and you need access_mod type name;

[fast briar]

Noted thank you. Now what Im missing is the property within the Monobehavior.
Which is this one.

[fresh salmon]

I'm not sure what you mean here

That code seems correct

[fast briar]

The code is indeed correct. Im trying to add it unto the base class, which is DataExcel.

Which is a child of another base class, Monobehavior.

Which CalculatedCollectedStars() is actually under.

[fresh salmon]

So you have a ClassA : MonoBehaviour, a DataExcel : ClassA, right?

[fast briar]

Yes.

[fresh salmon]

Just making sure as in that screenshot it wasn't the case.

[fast briar]

For Clearance, Both Shape and Test are children of DataExcel. And I declared DataExcel as a child of Monobehavior.

The reason I did this is because they have fields that i need to acquire.

My problem is that CalculatedCollectedStars() is another field I need, but it's under the parent of DataExcel.

When I about to make the string ForLoop, How can I call on CalculatedCollectedStars? Just call them all the same under MonoBehaviour?

[fresh salmon]

If I understand this right, you could create an abstract int CalculateCollectedStars() in DataExcel, and have each child class Shape, Test override it. Then you can use your regular foreach loop to call CalculateCollectedStars in DataExcel.

[fast briar]

Let me try.

[fast briar]

Stated that virtual or abstract members must be private, despite the screenshot I shown you of it's actual code put to public.

[fresh salmon]

You definitely can declare public abstract members -- are you getting a compiler error?

[fast briar]

Yes.

[fresh salmon]

What's the error message?

[fresh salmon]

cannot be private, not must be private

[fast briar]

Ah, my mistake.

[fresh salmon]

In depth: Declaring something as private does not expose it, even for child classes (compared to protected which does), so the child can't override.

[fast briar]

When i try to apply override to either Test or Shape, the error Im getting is stated to be not valid for this item.

[fresh salmon]

Not valid? Normally your override signature would be something like public override int CalculateCollectedStars()

Same return type, same parameters as the abstract declaration

[fast briar]

These are the errors im getting.

[fresh salmon]

Show the code of the method in DataExcel, it's originating from there

Looks like it's not marked abstract

[fast briar]

If i marked it abstract, another error happens, hold on.

Yeah, still errors.

[fresh salmon]

Weird. Have some sample code

public abstract class Base {
  public abstract void Method();
}

public class Child : Base {
  public override void Method() {
    // Implementation
  }
}

Call

Base b = new Child();
b.Method(); // Calls on Child because that's what really is in the variable, even if VS highlights it as a Base

[fast briar]

I should put the call within the Implementation Method?

[fresh salmon]

That call was an example, in your case if you have a List<DataExcel> you can call it on a single item, in your foreach loop

[fast briar]

I see.

Yeah whatever I do with CalculatedCollectedStars() nothing seems to work.

[fresh salmon]

I think you're reversing it

Abstract goes on the base class so the children can override it

And abstract does not have a body, overrides do

[fast briar]

Switching between the two still offers the same errors.

[fresh salmon]

Then see my example again, as I'm 98% sure my version compiles nope

Haha damn, I get it, abstract methods must be declared in an abstract class

Mark DataExcel as abstract.

(original code snippet edited)

[fast briar]

Ive gotten this one now on.

[fresh salmon]

Yep, so in that class declare the override and provide your own implementation

[fast briar]

Gotcha.

After all of that, the CalculatedCollectedStars() still has the same errors.

[fresh salmon]

You need to post the error messages. It will be faster like that

[fast briar]

Please refer to the two pictures I posted. They're still the same.

[fresh salmon]

Then post the updated code. There's still something that the compiler doesn't like

[fast briar]

Ive added the abstract unto the DataExcel also.

[fresh salmon]

Wait why is the abstract method suddenly in ShapesManager? And why does it have a body?
There's something about your class architecture I'm not getting

[fast briar]

Give me a bit, for you to have a better picture ill give you the entire code through a code bin.

[fresh salmon]

Alright

[fast briar]

https://hastepaste.com/view/U6wtCHIT

The important ones are DataExcel along with the child classes. The WriteCSV below is where i need to put my ForLoop on, specifically the lower WriteLine code.

[fresh salmon]

Yeah the abstract method must be declared in the abstract class DataExcel. Then all the classes that inherit from DataExcel override the abstract method

I think the whole class complexity and the abstract/override layer on top is screwing your perspective of it

what

Why is the override on the class now

[fast briar]

That's my mistake, as you said, it's screwing my perspective.

[fresh salmon]

I think that whole thing is beyond your knowledge for now

I suggest taking a step back and learning how it works in a separate project

[exotic basalt]

How do I make a 12 hour timer that runs when the app is offline?

[fast briar]

Yeah. I have to tell to my boss that the code complexity for class may be too lenghty to implement on a rigid code structure like this one, along with the fact that's it's beyond my knowledge.

Still, thanks for the help.

[shadow seal]

Google, don't cross post

[exotic basalt]

What?

[shadow seal]

I was about to answer you in #archived-code-general

[exotic basalt]

I have and so far none of the ways work.

Oh sorry

[shadow seal]

I don't see how you'd make a timer run while the app is closed

Do you just want to track the time between sessions?

[exotic basalt]

I am making a system that every 12 hours it resets the prices of a object.

I was thinking to get the current system time and if it is 12 hours or more past then it changes

[fresh salmon]

That's the best way, as you can't add a timer on a process that may or may not be running

And even if you create and run a separate process, they get stopped when the computer shuts down

So yep, comparing the app startup time to the last app shutdown time would be the best solution

[bleak gorge]

I have some problems with camera follow in a multiplayer game, I would be grateful if anyone can help me out?
Have googled but dont find any good solution

The lerp works fine, smooth movement but camera always stays on side, no matter what code i use it doesent work

Camera is separate and are looking for player transform

        Vector3 lookPos = character.position - transform.position;
        Quaternion rotation = Quaternion.LookRotation(lookPos);
        transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * 4.0f); ```

I want it to stay behind player without parenting it..

[stable spear]

@bleak gorge that sounds like offset is being calculated improperly?

[regal olive]

people can easily doctor that by changing their system's time manually, I would suggest perhaps using API to get the time via internet first, if internet isnt detected, fall back to system timer.

[exotic basalt]

Yeah but I don’t really care Cus I want it offline and online and it’s not like it messes up the whole game but thanks

[buoyant lantern]

Hey, not sure if this is really "advanced", but couldn't find anyone even asking about it, so, I guess. I have this problem where I want to display a world space text prefab over a certain boundary, nothing too hard(not that I would know how to do that, but a quick google search could probably help), but the boundaries are defined by a list of gameobjects so I somehow need to combine their colliders(or if theres a better way, please tell me.)

Btw, it is really important that these gameobjects are seperate objects for the game I am making.

So, just not making them a list but one object is impossible

[dawn shard]

what do you mean by over boundry? Like clipping through other objects? having a physical collider colide lettering with other objects?

[buoyant lantern]

No no, I am making a strategy map game

And I need a country name to display over the country

Which is made up of provinces

[dawn shard]

ah like a paradox game?

[buoyant lantern]

Yeah.

Guess you could say that.

[dawn shard]

and the text needs to arc/curve squeeze to fit in an irregular shape

[buoyant lantern]

Correct

The shape being of course made up of provinces

Which are stored in the list

[dawn shard]

ok first stem is to compost the provinces together to some kind of 'mask' shape

[buoyant lantern]

I dont think I get what you mean

[dawn shard]

and then a fitting of a generallized arc across that shape in an orientation thats readable (I assume north will be fixed upward on the screen)

lastly TextMesh Pro your name into that arc

[buoyant lantern]

Yes, but I dont get what you mean by mask shape

[dawn shard]

ah well the shape of each individual province, you have it stored as something right?

[buoyant lantern]

Correct

[dawn shard]

you need to stictch all that together into one shape first, by 'mask' I meant the combined shape

[buoyant lantern]

Ah, I see

Well, how do I do that?

I cant just unite them into one gameobject

Thats the problem

[dawn shard]

depends on how you implemented the shapes

[buoyant lantern]

Right now it is literally just squares.

I havent modelled a map yet

[dawn shard]

how are they stored? the stitching together will be dependent on how they are defined

[buoyant lantern]

In a list

Inside of the country script

[dawn shard]

no I mean how is the shape defined

[buoyant lantern]

With colliders?

[dawn shard]

ok see the green blob in your example, that is a province correct?

[buoyant lantern]

A country

Made up of multiple little squares

Like I said no map yet

[dawn shard]

oh so the provinces are just squares, and you have a list of the indexes of provinces that are part of the country

[buoyant lantern]

Yes

Although they wont stay squares

But right now they are

(Btw sorry for my bad english, I'm not form an english speaking country.)

[dawn shard]

ok well you could either write something simple now that assumes squares and then rewrite it when they change to other shapes

[buoyant lantern]

Yeah, thats why I came here, I have no clue on how to unite colliders

Because in order to display text over them the need to have one border, correct?

[dawn shard]

don't worry about uniting the colliders, you only need to worry about uniting 2D shapes

[buoyant lantern]

But they are 3d.

So 3d shapes

[dawn shard]

but your text will be 2D right?

[buoyant lantern]

Yes

Just a normal world space canvas

Or whatever works best

[dawn shard]

also is this land? like is your 3D just for mountains/texture etc like in paradox games?

[buoyant lantern]

Yes

If i get what you mean

If you mean, is this a plane? then no, those are individual cubes

[dawn shard]

ok and the Name to display will it be ok if it's ignores the 3D terrain, like the you want the text to be undistorted by mountains and such?

[buoyant lantern]

Nono, it will be higher than terrain

so no problems there

and it also wont be transparent enough to get distorted or unreadable

[dawn shard]

ok then it's definitly simplifies the problem to think in just 2D, resolving the shape of a country into a 2D shape

[buoyant lantern]

yes

still too difficult for me though

[dawn shard]

Is your world something odd like a simulated sphere or is it the more traditional wrapped cylinder?

or even just a flat plane

[buoyant lantern]

flat plane

but if you go to the edge it loops your camera back to the other side

so it simulates a sphere

but its a flat plane

[dawn shard]

like the game Asteroids?

[buoyant lantern]

I dont know what asteroids is

[dawn shard]

we call that a Torus world actually, if going off one side of the map takes you to the opposite side

[buoyant lantern]

I just remembered the term

Screen wrap

It simple screen wrapping

So, I guess torus world is the correct term

but Im not sure

[dawn shard]

dose going north cause you to apear on the south edge of the map? cause that's the key difference between torus and cylinder

[buoyant lantern]

Does it really matter

I havent decided on that yet

[dawn shard]

not really

[buoyant lantern]

Because I havent decided if you can rotate your camera, because if you cant you would end up upside down, but if you can, it would feel kinda off

So, I guess no

Atleast for now

so, cylinder it is

I guess

[dawn shard]

ok well combining individual provinces is the main challenge, even in 2D their are many ways it could be done. My sugjestion is to just create a seperate object which will hold the 2D representation and translate the provinces 2D 'shadow' onto it

[buoyant lantern]

Maybe I could use the existing country object which already holds the country script and stuff

[dawn shard]

that's a resonable place to put the code and store the resulting object

[buoyant lantern]

This is my hierarchy rn, so how would I do that thing you just said, with one of my country objects

The photonplayer is of course there for testing

[dawn shard]

I'm not entirly sure how to do it myself, I'm just looking for a general course of research you could follow in figuring it out

[buoyant lantern]

I see

Well, thanks for your help anyways

[dawn shard]

look your translating a 3D object into a 'shadow' aka a 2D silloute

[buoyant lantern]

Yes, yes

[dawn shard]

and for how to then composite these shadows together, this can be as simple as using a texture alpha value

[buoyant lantern]

okay

[dawn shard]

How tight fitting do the worlds need to be to the country? Is any overlap unacceptable?

[buoyant lantern]

They can overlap a little

[dawn shard]

like if their was a tiny little country inside of another

[buoyant lantern]

They could overlap

Definitlely

[dawn shard]

ok then just pasting the name right over the 'center of mass' so to speak would be adaquate

if a country had unconnected parts though would you want the name repeated for each part?

[buoyant lantern]

Probably

I have tried using CombinedInstances before to combine the colliders and get the center but something just doesnt work about them

So, you have an idea on how to get the center

?

[dawn shard]

well you could get the mid point between the farthest edges fairly easily

but a 'weighted' center is more complex

and detecting disconnected pieces is important, or else your weighted center might be outside the country

[buoyant lantern]

I think farthest edges is okay

Just implement a little check with trigger colliders or something

that it isnt out of borders

if it is seperated create two instances

[dawn shard]

If you had the countries shape defined, and then evaluaded each disconnected part seperatly to put a name in it

[buoyant lantern]

The shape is defined, my problemm is that it is seperate gameobjects that define it

[dawn shard]

take the country chunk and make a 2D mask with it, invert it so the collision is the non-country space. And then start growing a name inside of it untill it hits the edge, and you would have the largest possible name

[buoyant lantern]

That is a great idea

Thank you

[dawn shard]

you could even back up and rotate/bend the name to what ever degree you find acceptable to make it fit

[buoyant lantern]

Yep, that would probably be the best way

Now, making the 2d mask is the last thing in my way of good ui

[dawn shard]

Also you might want to try looking how Paradox games do their names, as they clearly figured out a solution for this problem

[buoyant lantern]

Yes, I know, but Clausewitz Code isnt really readable to me

Well, it is

But they handle everything way differently

[dawn shard]

yea different engine, at best a general strategy is all you be able to get

but in any case a 2D mask and compositing them together is a well understood problem you can likely search for solutions too

[buoyant lantern]

Yeah, you have any broad topic I could search for because searching "combining objects" or "2d mask of 3d object" isnt rellay giving mme the results I want

[dawn shard]

2d shadows of 3d objects

or 'projections/shadows of 3d objects/colliders to 2D'

[buoyant lantern]

Yeah, the second one is giving me some good results

Thank you for your time

You were really helpful

[dawn shard]

your welcome, good luck, oh and out of curiosity where do you hail from?

[buoyant lantern]

Im german

[dawn shard]

your english was not an issue and I won't have know you weren't a native speaker if you hadn't said so

[buoyant lantern]

Well, thank you

I dont know if you are a native speaker, but in any case yours is also very fluent

[dawn shard]

my spelling on the other hand...

[buoyant lantern]

Is very good, what do you mean?

Except for some exceptions, like 3 (which can honestly happen to anyone), i barely noticed

[dawn shard]

well I'm just very bad at spelling generally, without spellchecking it will look terrible

[buoyant lantern]

Ok

Well, is it like dyslexia or just bad

[dawn shard]

just bad, I spell everything phonetically

If I was Italian this would not be a problem

but English spelling has next to no connection with how a word is pronounced

[buoyant lantern]

That is true

[leaden jungle]

that's funny I want to do the opposite with a game project 3d into 2d 😛

[exotic basalt]

I am making a system that every 12 hours it resets the prices of a object. How would I do this?

(Feel free to @ me)

I was thinking to get the current system time and if it is 12 hours or more past then it changes

[livid kraken]

Current system time can not be trusted. Get your time from a trusted source @exotic basalt

[flint sage]

Doesn't really matter if it's an offline game

[austere jewel]

Depends if you're okay with a game that can be abused by modifying time. If it's extremely casual then it may not matter. If it's not, then system time is not okay

[flint sage]

You don't have much of a choice except to trust it if you've a local game

[livid kraken]

I once used a product that used system time to evaluate its 30 day free trial 😆

[somber tendon]

you can use worldtimeapi.org for development, not recommended for production as their faq says

[flint sage]

Probably doesn't matter, the people abusing it were likely not going to buy it anyways

[bleak gorge]

Offset is just a vector3(0,4f,7f), i have hard times understanding that functions,
Do you have any idea what i need to do?

[hollow pollen]

What server solutions do you all use? There are already so many different reedit threads on the different solutions and weather or not it is a good idea to make your own. What do you guys think?

[compact ingot]

Many real projects that require max. performance use custom net-code, a custom (virtual) server on an established cloud platform with a scalable architecture. This means different things for different projects and can't be generalized. Also depends on how much money you have. What you don't do is build a server in PHP/Node using HTTP and a REST API.

[flint sage]

Custom

Eh, a php webserver can work fine

Lots of games probably still run on something like that

[compact ingot]

i said "need performance"

and the point was more about the REST/HTTP thing

[stable spear]

"offset" is controlling the offset between the camera and character. That means 0 units in the x-direction (usually rightward), 4 units in the y direction (usually up), and 7 units in the z direction (usually forward, but can switch between left/right and forward/back depending on the rotation)

[rocky atlas]

Hey, I'm making a cursed FPS game and I want my player to teleport around the map when I press a button. But I don't even know what to search or how to start making the script.Anyone know what to do?

[shadow seal]

Randomly teleport, or set waypoints?

[rocky atlas]

randomly teleport on set locations

[shadow seal]

Ok, make an array of Transforms for your positions (Or Vector3's but I'd use empty GOs) then get a random element from there and set the player's position to it's position

[rocky atlas]

ah

Wait, why an array of transforms. Why can't I just create a few empty GOs and then tp to them randomly?

[tropic lake]

yes emtpy gameobjects you can store them as type Transform

[rocky atlas]

ah, alright

[woeful trout]

How might one develop a coordinate system for tiles on a goldberg polyhedron (geosphere, hexsphere, there isn't really a catchier name)

[dusky niche]

Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak

how do i find whatever the fuck is causing this??

im getting serious lag from this

[tough tulip]

http/rest for persistent data and sockets for realtime duplex data transfer

[dusky niche]

and it happened randomly after building

[novel wing]

It's internal most likely. If it's your own code make sure to turn on leak detection to find the source, assuming you use com.unity.collections

[dusky niche]

idk how the fuck to remove com.unity.collection

watch a video to remove i

it

and it literally automatically adds itself

if i close my project

its like a cancer

i even downloaded entities

like other recommended

[novel wing]

you're probably using a package that depends on it

Entities for instance does depend on it

[dusky niche]

thi is causeing my online game to be neeerly unplayable

and i only added a single listener in player bases looking to see if the player can move

if(bool){ move();}

[kindred tusk]

Would inclusion of a package have any impact on your game if you're not using it?

[dusky niche]

its online so, im using playfab for user IDs and using mlapi

[woeful trout]

Okay, better question

Where can I go to get some insight into my first question?

[dusky niche]

my database is just a server side http to aws arurora DB

[novel wing]

I remember a guy wrote about how he solved it like a month ago, so check #archived-code-general if you can find the post

Can't remember his exact name though unfortunately

[woeful trout]

Rockin

Can you remember any key words he used in his post, so I can use the search function?

[dusky niche]

mm nice

omg unity

[woeful trout]

XD

[novel wing]

Not really no, maybe some of the words you used?

[woeful trout]

I'm not sure what I'm supposed to be looking at, but I to feel "omg, Unity" quite deeply

[dusky niche]

@novel wing https://docs.unity3d.com/Packages/com.unity.memoryprofiler@0.2/manual/workflow-memory-leaks.html how the fuck do i atach the memory profiler, doesnt even say where to find it in unity. omg unities documentation is sooo bad for first time use.

Attach the Memory Profiler to the running Player. For information on how to do this see Capture a memory snapshot documentation.

okay, how about 1. is WHERE the fuck i find it

jesus christ

lol

i dont have memory profiler

would entities do fine? lordy

@novel wing what is GhostStatsSystem

thats the memory leak

[novel wing]

Can you stop tagging me on every single post you make?

DOTS is still in preview of course shit's going to be broken and buggy. Check the forums or #archived-dots if the docs are insufficient

[carmine geode]

hey guys, i need some help with a combat system, is there a good tutorial on where to start?
it's for a fighting game so i just need a ability/moves system, a damage system, a buff/debuff system, maybe a consumable system, but no need for an inventory system

[urban warren]

Most likely not. And if there was it most likely wouldn't work for your game's needs.

[compact ingot]

at some point, there are no more tutorials, basically if you ask in advanced code, tutorials are over.

[dusky niche]

Again, thanks to no one, i found the issue and fixed it. God seriously wonder sometimes what this discord is even good for..

[carmine geode]

oh ok i just thought that this question would go here as people didn't answered me on general

[urban warren]

I can point you in the right direction. You most likely will want to use ScriptableObjects for buffs/debuffs. For an ability/move system this really depends, maybe a finite state machine could be used?

[compact ingot]

the question is very general, no simple answer, and nobody fancied getting into a long discussion.... probably

[carmine geode]

ok, atleast it seems i am/was on the right direction (i'm already trying just having some troubles on the interactions), well thanks! will try to search more, sorry for posting here

[urban warren]

Dude, it was 45 minutes since you asked. This isn't a live helpdesk, if people are around and know the answer and have time, they will answer. It helps though if you ask questions in a polite, clear, and concise way.

[urban warren]

All good! Good luck, and if you have more specific questions you can always comeback to ask (either here or #archived-code-general depending on the question of course)

[carmine geode]

ok thanks!!

[gusty rivet]

#if UNTIY_EDITOR is resolving as false even though I am not trying to make a build

UNTIY ?

[plain sable]

Hello chaps, does anyone have any idea how I could go about generating a random number based on some input, Ideally it needs to be seeded so for example, say you visit vector 0,0,0, then you got really far away and return back to that position, I want the same items to generate in the way they originally generated. My end game is to create a procedural road with some simple turns in, and when you return to certain parts of the road, you see the same turns and generation as when you were last there.

Using random.initstate() is not viable because I cannot control the generation order

[fresh salmon]

Try storing the vector's hash code theVector.GetHashCode(). It's an integer value that, if well implemented, should be unique for each vector.

[plain sable]

ill give it a try now, I did try a couple of hashing functions I found online, and that worked however the numbers I was getting for each vector were insanely huge

[fresh salmon]

You'll also get huge numbers, maybe even negative numbers, but still contained in an int, so not that big. Shouldn't be an issue

[plain sable]

Yea I am getting some more reasonable numbers at least now

seem to be unique for each vector position and I get the same return when I input the same vector

[fresh salmon]

For it to work, you'll also need to check that two new Vector3 with the same XYZ values return the same hash code

Oh alrighty then

[plain sable]

Only problem is, how could I implement a seed, so its not the same outputs for each game, I guess I could just multiply the hash code by the seed?

[fresh salmon]

Sounds reasonable, if the seed for a world is unique

You could make the seed a Guid and get the hash code of it, then use that to multiply the vector hash codes with it

[plain sable]

yup, I could probably just get away with a random int or something

[fresh salmon]

Reduces chances of collisions

[plain sable]

that would work also but possibly a bit over the top, although yea as you said collisions could sprout up

basically the biggest downfall of hashing

Well thanks for your input @fresh salmon , I think this gives me a decent place to start.

[compact ingot]

Vector3 hashed to integer cannot be unique… best case is each hash can occur for 3 different vectors…. Also, I’d try to make the deterministic part of worldgen integer based…. Just more robust

[plain sable]

yea I didnt mean unique as in unique on each game instance

I just meant unique compared to other vectors, but I understand your point

[fresh salmon]

You tell that (0,1,2) and (0,2,1) have the same hash codes? Better check that, if that's the case then the implementation is bad

[plain sable]

basically yea, I just need a deterministic way of generating random values based on some input such as a vector.

0,1,2

0,2,1

[fresh salmon]

All good!

[compact ingot]

Does it have to be a float vector?

[plain sable]

I mean ideally yea, but int would be fine I think for this application

[compact ingot]

Cause, unless you store that vec3 for future reference you are very likely to never find it again

[plain sable]

I think maybe I would need to get deterministic values using some sort of grid based system then

[compact ingot]

And if you use a grid, you can just use integer vectors

[plain sable]

because you are right

[plain sable]

my thoughts exactly

because you are likely to return to the same grid

but not float vector

as you said

[fresh salmon]

For that application they don't need to
Player visits position, hash code is stored.
Players wanders around and comes back to the same pos, the hash code is compared with the ones stored into the collection

[plain sable]

So I would generate a deterministic value for each grid?

maybe I can visualize my problem better for you

[fresh salmon]

And you could also use a HashSet<Vector3> or a Dictionary<Vector3, ?> to store the cached positions, and eventually some value linked to them

[compact ingot]

Same principle as before for float vectors… jzstvthat you can actually return to them

[plain sable]

let me mock up something

Imagine this simple road/path

[compact ingot]

For stored float vectors you‘d maybe do a nearest neighbor lookup…. For that you need a tree optimized for spatial lookup

[plain sable]

the only parts I am needing to procedurally determine are where a turn should take place

but importantly you should be able to travel 1000 miles out, return to the same position and the turns be the same

if this makes sense

[plain sable]

I think a solution like this would be overcomplex for what is required

[compact ingot]

It does… that’s how all proc-gen worlds work

[compact ingot]

Hehe, maybe…. But those can be found on GitHub and used almost like a dictionary

[plain sable]

So how would you suggest approaching this problem? I mean I was origionally thinking I would place a turn tile based on a random number associated with that tile/position

So maybe for example if the generated number associated with that tile can be divisible by two, there is a chance a turn tile could be placed there.

[fresh salmon]

That could do it for a simple system like that

Hash code divisible by some prime number? That's a left turn.
Divisible by some other prime number? That's a right turn

[plain sable]

yea something along these lines

it just comes down to how to generate the number for each tile, and how I would get the grid system implemented to work with this.

[compact ingot]

There are a couple of abstract grid systems (grid math libraries) on GitHub that would help with this.

[fresh salmon]

Yep, making the link between the grid system and the random number is the difficult part. You have to adapt it according to what the link can do (get a grid pos from hash code, the inverse, both?), and what you're planning to do with it

[plain sable]

ok I think I have some what of an idea of how I could do this, some kind of lookup to get the current grid pos which would be a integer vector position and then possibly use the hashcode of this int vector along with some sort of division check to consider what the tile should be.

Maybe,

anyway, appreciate the help guys, ill give it a shot

[fresh salmon]

Just remember that if you're determining turns using division, make sure to divide with a prime number so you don't possibly get two "valid turns" for a single cell!

[plain sable]

A very good point, thanks, its that or for example if the number can be divisible by 2, I would then pick randomly between left or right. But dividing by prime numbers may be a easier and cleaner solution, perhaps even slightly more performant as it eliminates an extra operation.

[fresh salmon]

I would pick randomly between left and right
No! Because if you come back to the same position there will be a chance where the turns won't be the same due to the RNG!

The generation should always be deterministic (is that the correct term?), ie. always the same for a specific value

And just realized, your drawing above has effectively a case where there are two turns for a single cell, you might not want prime numbers after all, but two numbers where there is a low chance of a hash code being divisible by both of them at the same time

It all depends on the structure of the map you want to make

• i have a generic Shooter<T> class that can spawn any projectile as long as T is a type of Projectile. each of my boss enemies have around 4-6 of them (attached to their own child gameobject) that get enabled one by one based on its life count (first one starts enabled, second one gets enabled once first life is gone, etc.)
• inside the class contains a System.Action called AttackStartAction that gets invoked in OnEnable
• my UI system wants to subscribe a method to that action so that it can display an attack name string on the screen when the attack starts

but i can't think of a way to loop through the Shooters and grab each Action.
because if i do something like

for (int i = 0; i < boss.transform.childCount; i++)
{
    boss.transform.GetChild(i).GetComponent<Shooter<Bullet>>().AttackStartAction += OnAttackStart;
}

void OnAttackStart() {  /*show attack name*/  }

then it'll only find scripts of Shooter<Bullet> and not Shooter<Laser> nor any other T that inherits from Projectile
but if i do

boss.transform.GetChild(i).GetComponent<Shooter<Projectile>>().AttackStartAction += OnAttackStart;

then it'll find nothing 'cause none of my projectiles are exactly of type Projectile, they're all some class that just inherits from Projectile

is there a good solution to this?

[long ivy]

define an interface for Projectile that exposes the AttackStartAction, and use GetComponent on that interface instead

[tepid dove]

oh wtf you can do GetComponent on interfaces

[wintry pawn]

I have no idea where to ask help for this 😄
I have many dynamic sprite renderers in a 3d world and when all they are on screen 50% of CPU ms get on this script:

CreateSharedRendererScene. If I hide all sprite renderer CullScriptable takes only 1ms vs 10ms with sprite renderer visible. I have also disable dynamic occlusion in debug mode but nothing different happened. Any help? thank you!

[untold moth]

Are they all visible/need to be visible at the same time?

[wintry pawn]

yep, I'm hiding these gameobject in other way and distance draw is not so big. So I really don't care if unity occlusion is working on these spriterendere. Even if the system is rendering a sprite that is behind a mesh it's ok, it's not so bad in performance

I'm testing now with deep profiler to see better

[untold moth]

I'm not sure if you can disable frustum culling for specific objects...

[wintry pawn]

for testing purpose I'm able to disable frustum culling on every objects?

deep profiler is not helping me a lot. still 10ms on this function when many sprite renderer are on screen

[untold moth]

Not sure about that either. It's part of the render pipeline afaik.

[wintry pawn]

ouch, not good having 50% of cpu time on culling script when culling is not needed 😦

[untold moth]

Consider that all that cpu time(or more) is probably going to go into draw calls instead.

What you could do is use gpu instancing or combine the meshes into 1 mesh.

[wintry pawn]

yep I know, but now 50% of cpu times gets in "CullScriptable" 😄 profiler is from a build, not editor

[untold moth]

Probably the same thing. Or did you change anything?

[tired creek]

    public float spawnDistance
    {
        get { return _spawnDistance; }
        set
        {
            _spawnDistance = value;
            Debug.Log(_spawnDistance);
            CreateTrackElements();
        }
    }
    float _spawnDistance = 0.2f;

Is there a way to make spawnDistance show up in the inspector?

[sturdy edge]

all i could find were workarounds :/
https://stackoverflow.com/questions/40554418/in-unity-can-i-expose-c-sharp-properties-in-the-inspector-window

[agile yoke]

You can make _spawnDistance show up (and be serialized), but changing it won't invoke the setter of spawnDistance then.

(Or write a custom editor if you deem it worth it, then you can do whatever)

[tired creek]

yeah, thats the problem

I want to have a track with customizable distance between its elements, having it update live in the play mode as i fine-tune the value in the inspector would be nice

I mean I dont need the setter to work in editor mode, but i want to be able to mess with the value in play mode and have it update automatically

hmm

i could use a slider ui element and connect it to setter?

[agile yoke]

With your own UI (in-game or in a custom editor) you certainly could, yeah

If it's only in play mode, you could also just check if the value changed in Update

or in OnValidate perhaps

[sage radish]

If you change the Inspector to Debug mode, it will show all fields, private or public, serializable or not.

[fervent parcel]

hey guys, trying to refactor this but failing hard:

into something like this:

[agile yoke]

In the second image, try casting to T, not type

(and remove the type parameter entirely)

[fresh salmon]

You shouldn't be needing the type argument, just cast to T in the body

[sage radish]

And there's no reason to cast it from int to the enum type and back to int

[tired creek]

Idk, doesnt show up

        get { return spawnDistance; }
        set {
            spawnDistance = value;
            Debug.Log(spawnDistance); 
        }
    }```

[fresh salmon]

That's a property

[agile yoke]

EnumPopup takes and returns Enum, not int

[fervent parcel]

like this?

[tired creek]

i need a setter

[fresh salmon]

If you need to serialize the field, then serialize spawnDistance

[sage radish]

You won't see properties, but you can see fields. I don't know why you posted a different version of your spawnDistance property. The other one works, this new one will cause an infinite loop.

[agile yoke]

Using debug mode for the inspector just doesn't help with the problem at all here. The goal is to invoke the setter when changing the value, debug mode won't do that.

[fresh salmon]

Oh good spot, it's a stack overflow right here, got thrown off by the naming of the property

[sage radish]

My bad, I read the question wrong.

[agile yoke]

hm, looks like that might not work with generics then. You can probably just ignore the actual type and cast the index to Enum and the returned value to int directly, I think

[fresh salmon]

Yeah you can't as an Enum is not always on an int, could be a byte or whatever. A solution would be to cast to object, then to int

[fervent parcel]

I can just do this to get rid of the Int

[fresh salmon]

That boxes the value, but should be only a minor performance drop

[fervent parcel]

but I still cant get it to work

[fresh salmon]

What's the error message? "Cannot convert int to T" right?

[fervent parcel]

yes

[fresh salmon]

There should be a workaround with Enum.GetValues to get a value by index

[hasty hinge]

JESUS IT JUST DONT WORK(wallruning

[fresh salmon]

Update: Can you try with something similar to this? It could work using Enum.GetName

Haha it won't work actually, the arg expects a type T and that method returns a string

[fervent parcel]

testing this:

I am just trial and erroring at this point

yup didnt work lol

[fresh salmon]

Yeah, a generic version of EnumPopup could be handy here, but there isn't

You would need a Dictionary to link an int to a T and use that somehow to pass that to EnumPopup

public T Test<T>(int val) where T : Enum {
  T[] values = (T[])Enum.GetValues(typeof(T));
  return values[val];
}

This seems to compile and return the expected value

[fervent parcel]

looks good

testing it now

[fresh salmon]

That will not work for enum values with a gap in them though, or anything else where the array indexes don't exactly map the enum values indexes

[fervent parcel]

its working

though I feel like I have done it in a very stupid way

wait, I feel like I have lost complete reason of why I was doing this

ummm

lol

thanks a lot for the help, need to take a step back and take this all in

[fresh salmon]

Holy hell, that's what I call shitcode. That version will work with enums with non-linear values

public static T GetEnumValue<T>(int val) where T : Enum
{
    Dictionary<int, T> d = new();
    foreach (int value in Enum.GetValues(typeof(T)))
    {    
        d.Add(value, (T)Enum.Parse(typeof(T), Enum.GetName(typeof(T), value)));
    }
    
    return d[val];
}

I hate what I just produced

[blazing slate]

why don't you just cast the enum ?

[fresh salmon]

Because it can't

return (T)val doesn't compile because enums are not always int

[blazing slate]

casting it to an object should work

like (T)(object)val

[fresh salmon]

Yeah I expressed it above and it works, then we got lost in all that

[compact ingot]

is it really shit code when dealing with serialization and adapters... they often have to bridge language barriers and having reflection in your language to make that somewhat simple is a godsend ... wouldn't want to code that in c++

[solar otter]

So I have been trying to make Custom Inspector. And now I have come to a problem, maybe one of you knows the answer to that problem.
So I want to create EditorGUILayout.MaskField() which represent my LayerMask. While I know how to set the label and the int, I am having trouble getting the string[] from my Layermask. How do I get that?

[fresh salmon]

Hehe another way would be to do

public T GetValue<T>(int value) where T : Enum {
  return Unsafe.As<int, T>(ref value);
}

Greatly reduces the line count and increases execution speed, but as the name suggests, screw up the programming and your whole process may break, or you get unexpected values

Unsafe.As is so fun to work with, you can dump the whole heap with it, cast something to something else that would never compile if it was made with a regular cast

[compact ingot]

I've known some Rust programmers who raved about how great the language is and they never have trouble getting stuff to compile... guess how they did that 😉

[hollow garden]

Rust 🤤

macros are by far the most useful thing i've learned in Rust
you can compress down like 400 lines of trait implementations into a single macro 😩

[pulsar isle]

Let's say I have the 3D Model of a Dice. I want to take its textures, convert them to an mp4 and play it as a video texture in a no-texture version of the dice(a cube basically) in a way that will appear like the "normal" textured one. How can I do this ?

like, wrap the mp4 arround the cube in way that will closely resemble the dice textured one.

[untold moth]

Not quite sure what you mean. How can you wrap a video file around a mesh..?😅

[pulsar isle]

maybe by doing a hack on each frame of the video

[untold moth]

I'm still not sure what you mean.

Is there like a video of the cube and you want to extract the texture that is used on that cube?

[pulsar isle]

Hmm no. I need to rephrase a bit cause I got you confused. Give me a minute.

[sage radish]

Why video? Is it an animated shader/material?

[pulsar isle]

Nope. I just want to do it this way cause the size of a video(for video texturing) is far smaller than the individual sizes of each texture.

so I thought I could use a video to "fake" the textures of a 3d model

[untold moth]

You only need 1 texture though. And I'm sure you can compress it to be less than a video.

fake like display it on a quad?

[pulsar isle]

I simplified the use case. What if I have 100 objs with 100 4k .pngs ?

[untold moth]

You want to change the quad texture to mimic a rotating cube?

Well, whatever you have, 100 4k pngs is gonna be better than a video containing the same pngs.

[pulsar isle]

Sigh, I guess I have to re-examine what I want to do.

Thanks for your input though. It was invaluable.

[worthy lodge]

I use string currentDir = System.IO.Directory.GetCurrentDirectory(); to get my current folder, but it does not work if there is a special character in the folder. Does anyone know how to fix this?

[fresh salmon]

Can you elaborate on "does not work"? Does it throw an exception, is the returned path invalid? Also what's that invalid character?

[worthy lodge]

it was a +

And I do not get anything in my array with the code:

string path = System.IO.Directory.GetCurrentDirectory();
        DirectoryInfo di = new DirectoryInfo(path);


        foreach (var fi in di.GetFiles("*.vrm", SearchOption.AllDirectories))
        {
            
            //Debug.Log(fi.FullName);
            allVrmPath.Add(fi.FullName);
            allVrmNames.Add(fi.Name);
            // fi.FullName
            //allVrmPath = 

        }```

It was a bug report and I did not have the time to transfer the project to a folder with a character in it yet, so couldnt debug it

[fresh salmon]

And that works if there's no + in the path?

Seems like it works on my machine, with the + or not (Windows doesn't prevent it from being inserted into a file name or folder name)

[hasty hinge]

hello

[worthy lodge]

Yep, removing the + from the folder fixed it for him (full path was C:\Users\USER\Documents\ +Projects\STUDIONAME\PROJECTFOLDER)

Ahh it might have been de backslash combined with the plus

I see discord had issues with it

[kindred tusk]

If you're using backslashes in a path you need to either use a verbatim string or escape each one:

var x = @"Path\To\Folder";
var x = "Path\\To\\Folder;

[modest lintel]

escape the escape character

[kindred tusk]

But you can (and should) use Path.Join instead.

[fervent parcel]

I did it

Thanks so much for all the help

Honestly It was mostly trial and error

[kindred tusk]

Oh, you need to add a guard there to prevent a multi-select error

If you share code instead of an image I'll show you.

See #854851968446365696 for how to format code

You're going to get deleted if you paste it without a codeblock

[fervent parcel]

weird

wont let me edit it

Nor delete it

public void myEnum <T>(SerializedProperty serializedProperty) where T : Enum
    {
        serializedProperty.enumValueIndex = (int)(object)(T) EditorGUILayout.EnumPopup(
            (T)(object) serializedProperty.enumValueIndex, myEnumStyle());
    }

[fervent parcel]

ahh

[kindred tusk]

public void myEnum <T>(SerializedProperty serializedProperty) where T : Enum
    {
        var next = (int)(T) EditorGUILayout.EnumPopup(
            (T) serializedProperty.enumValueIndex, myEnumStyle());
        if (next != serializedProperty.enumValueIndex) {
          serializedProperty.enumValueIndex = next;
        }
    }

like this

Otherwise if you select multiple instances they'll all take the same value of the first one, even if you don't change the dropdown

It's a weird thing

It's just the way multi-select works

getting the value reads just the first selected, whereas writing it sets all.

[fervent parcel]

thanks, let me try to replicate the error first so I can better Understand it

what do you mean by this "Otherwise if you select multiple instances they'll all take the same value of the first one, even if you don't change the dropdown"?
Cant seem to replicate it

let me take a short clip

https://puu.sh/IiweW/cfbb17fbc8.mp4

Sorry, I am kind of a noob

[agile yoke]

If I understood it correctly, try setting the two objects to different values, then select both but don't change the value, and then select each individually again

and see if they still have their previous value

[fervent parcel]

ok

Nop, no conflict

[agile yoke]

hm, idk then

[mossy magnet]

I need some help, I am using Mathf.PerlinNoise to generate a noise map, when I input larger values into the seed of the perlin noise ||Mathf.PerlinNoise(seed.x,seed.y)|| I get some wierd results, like larger squares. This usually happens when the values get above 2,000,000. Is there a way to fix this, or do I just cap the seed at 999,999?

[lavish sail]

I'd cap the seed, I wouldn't work with 7+ digit numbers without a good reason

[mossy magnet]

ok, that's a bummer. I might also look for some other noise solutions, custom ones

[untold moth]

You're supposed to use a value between 0 and 1 afaik. Also it's not a seed, but position on the noise texture.

[lavish sail]

Also yeah, I don't think Mathf.PerlinNois-

[mossy magnet]

ooohhhhh

[worthy lodge]

Since I use GetCurrentDirectory() I ended up using the verbatim, thanks!

[merry sonnet]

I have StreamReader with png data, is there any way to get that png open as a sprite without creating temp file?

How about mp3 or ogg as AudioClip?

[kindred tusk]

At runtime?

You don't need to create a file. You can just read the stream into a buffer and pass it to a Texture2D

@merry sonnet https://docs.unity3d.com/ScriptReference/ImageConversion.LoadImage.html

You can load a byte[] of PNG data

[merry sonnet]

yes, runtime

I actually found that ImageConversion right after asking it

[kindred tusk]

Read the complete stream into a byte[], then use the above.

[merry sonnet]

but now problem is with audio

[kindred tusk]

Audio I'm not sure.

[merry sonnet]

yea, I got image working already

[kindred tusk]

https://docs.unity3d.com/ScriptReference/AudioClip.SetData.html

this maybe?

[merry sonnet]

setdata is for raw wave data, but ogg is compressed

[kindred tusk]

https://docs.unity3d.com/ScriptReference/AudioClip.Create.html

Somehow using this: https://docs.unity3d.com/ScriptReference/AudioClip-loadType.html

I'm not sure actually

[merry sonnet]

I have idea for fallback using temp file and UnityWebRequestMultimedia, but that solution feels so uggly hack

[kindred tusk]

Yeah, looks like that might be the only way.

Or you can use an ogg library that converts it to raw bytes

And use AudioClip.SetData

If you do go the file route you should write them here: https://docs.unity3d.com/ScriptReference/Application-temporaryCachePath.html

[merry sonnet]

yea, I was thinking about this too, but didn't find any easy and simple solution for that, so probably using UnityWebRequest

[kindred tusk]

You could try integrating this? https://github.com/NVorbis/NVorbis

Not all c# libs work with unity though

[merry sonnet]

good point, I was planned to use persistent data and delete after use, but that is better.

[kindred tusk]

I'd just go the file route though

Rather than wading out into the unknown

You can always replace it later

[merry sonnet]

yea

thats true

thanks

[rugged radish]

hey guys, not sure if this is advanced enough
I'm trying to find fast(er) alternatives to Poisson disk sampling to build a bunch of random point clouds
any keywords that would help googling would be a great help

rn it takes 1 second to generate 1 200x200 cloud which is terrible since I want to generate around 1000 and probably increase the size as well

and please correct me if I'm wrong, but I can't put it into jobs since allocating Random instances inside jobs will kill the performance

[hollow garden]

you can, you just gotta do it smartly

you can split the grid it into buckets and generate the stuff in parallel

here is a good article on such a thing https://medium.com/@1basudevpatel/faster-poisson-sampling-a76cb9a99825

[rugged radish]

this looks very interesting, thank you 👍

[hollow garden]

👍

[rugged radish]

I probably need to revisit jobs, as I had the idea of running multiple parallel jobs with the serial implementation. But I thought that passing non-blittable types (System.Random in this case) poorly affects performance 🤔

with buckets running in parallel there should be the similar limitation

this is something I need to revisit anyway though

[hollow pollen]

I don't know if this is advance or general but what might a reason be for only getting an error from build an not when you play the project from the editor?

[orchid marsh]

Knowing the exact error would help you and others determine this better.

[warm adder]

Hya, quick question which I think might be more suited here in the advanced chat

I need to get references Inside my code to the InputActions I added to my Input Action Asset. I got a reference to the asset itself, but I cannot access the maps within the asset.
The docs are very unclear on how to do this

Im finding stuff like inputActionAsset.GetActionMap which doesnt exist etc. Anybody a clue?

inputActionAsset.actionMaps is an array, but it's always empty

[misty glade]

Sorry, and you're using a callback model?

Like, you've got your reference to the input actions, and you're subscribing to the event?

i think it's actionTriggered or something

(like with):

myActionMap.actionTriggered += myHandler;
public void myHandler(... i forget .. some context parameter thing ...) { ... do your handling ... }

[warm adder]

Hya. No not really. So far I've been using seperate Input Actions, enabling them one by one, etc. Now I want to use InputActionMaps and Assets. So I've build an asset, added a map and some actions, but I cant seem to figure out how to reference those maps (and therefore also the actions)

So from ActionAsset to ActionMap is the problem

I think I'll be able to handle subscribing and such once I can get acces to them

[misty glade]

ok so you have an actionMap - you'll need to subscribe to the callbacks that it fires when it receives those actions

maybe I'm not understanding your question...

[warm adder]

Yes, actionMap is in the action asset

So I got a ref to the ActionAsset, public InputActionAsset playerControls;

But, I cant get to the map inside the asset. playerControls.actionMaps.Count is always 0, and the script reference on how to do it is very scarce

[misty glade]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/ActionAssets.html#creating-input-action-assets you went through that already?

[warm adder]

So I had assumed that, with 1 map added to the asset, to acces that would just be playerControls.actionMaps[0]. something, but that always fails

[misty glade]

I haven't used this in a while TBH.. but I seem to recall it worked pretty well out of the box. Maybe the generate-code feature will help you get started?

[warm adder]

yeah i've been stuck on those pages for an hour now lol

Also tried generate code, no luck. It doesnt really do that much in the first place tbh

[misty glade]

Hm.. I don't know off the top of my head, sorry..

[warm adder]

No prob, i already appreciate the attempt to help 🙂

[misty glade]

I mean, also ensure that you save your PlayerControls object - i see a * there - dunno if that's the issue, but I saw a sentence that said the input maps aren't saved alongside the scene

[warm adder]

PFFFF thanks hahahha

that was it

tiny little Save Asset button at the top

Yeah, playerControls.actionMaps.Count is now 1

auto generated code now also makes sense, now that its Actually adding stuff haha

[misty glade]

.... a word file? yeah, no

[fervent parcel]

its how I write my notes 😄

want a picture?

[misty glade]

I suppose..? I mean, just saying, posting a word file in a discord isn't a great idea for a variety of reasons

[fervent parcel]

tell me if this makes any sense guys

[misty glade]

you're asking people to trust your file which might have malicious macros, you're trusting people with potentially embedded personal information, you're requiring that people use windows/word.. etc

you color coded it too..? 😛

[fervent parcel]

haha true

yea I color coded it haha

[misty glade]

This.. explanation? question? commentary? is .. scatterbrained.. I don't have any context for what you're asking or telling me

[fervent parcel]

does my explanation make sense?

coz honestly I used pattern recognition and trial and error to make the code work and I want to understand it

[misty glade]

I don't even know what you're trying to achieve or what your problem is...?

(and I'm trying to understand it but you're burying me/us in details that you're not explaining)

[fervent parcel]

I refactored code A into Code B

[late solstice]

Instead of making a grid with pixels like this, is there a way I can make it so the player can edit it in the game?

[misty glade]

Why? what's code A trying to do? why'd you refactor it? etc

@late solstice Absolutely, but this isn't an advanced-code question. It's more of a design question or .. #💻┃code-beginner question.

[fervent parcel]

//From this 
        DataMode.enumValueIndex = (int) (SearchIntegrationWithTMP.DataMode) EditorGUILayout.EnumPopup(
            (SearchIntegrationWithTMP.DataMode) DataMode.enumValueIndex, myEnumStyle());
        
        //To this
        myEnum<SearchIntegrationWithTMP.DataMode>(DataMode);

[late solstice]

Thanks sorry for putting it here I didn’t know where else

[fervent parcel]

I call it many times so I shortened it

[misty glade]

NP. If you don't know, though, it's probably in #💻┃code-beginner 🙂 You'll have to figure out what you're trying to do, though, before you ask. Do you want 100 buttons that the user can click and it edits your matrix? Do you have an image that they can click? etc - your question is too broad as it is

[late solstice]

Like a grid, where the person can place pixels and remove pixels, im trying to make conways game of life.

[fervent parcel]

many ways to do this, you can use GUI buttons for one

each button representing a specific index

[late solstice]

Thanks, ill try to find a tutorial or something

[misty glade]

@fervent parcel why are you casting your enum to an int anyway?

Why not just...... use the enum

like I'm trying to wrap my head around why you're doing all this double casting as some sort of ... Adapter pattern, and don't understand

Anywhere in your codebase that you're using Enums, use Enums (unless there is a specific reason to translate them to/from ints)

[fervent parcel]

can you show me a workable example, I mean I would love to shorten it but failed

[misty glade]

I mean, tell me what you're using your enums for and I'll show you..

I can show you mine, but they .. are .. I dunno, enums are kind of a core concept

My application is different than yours

[fervent parcel]

https://puu.sh/IiAz4/e316089406.mp4

just a custom editor enum

[misty glade]

right so, show me the code that switches the gui

I hope you're not doing something like...

if (displaymode == 1) ...
else if (displaymode == 2) ...

[fervent parcel]

this

both examples work

first one is how I normally do it

[misty glade]

i mean, how are selecting what to display, in the editor

where do you consume the enum value selected by the user

maybe paste the entire editor script into pastebin.com

[fervent parcel]

this is a unity editor function
EditorGUILayout.EnumPopup

[misty glade]

yes, i know.. and i know what it does

Paste your script. 🙂

Because your call to EnumPopup() should look more like:

public DataMode userDataMode; //somewhere in your declarations
...
userDataMode = EditorGUILayout.EnumPopup(DataMode.default, myEnumStyle);

[fervent parcel]

Not sure I am allowed to, I am just updating the way this asset inspector looks, this is actualy an asset on the asset store

so I am doing it for a company called smitesoft

[misty glade]

well... you're doing something.. odd (or potentially wrong) and.. my sense is that there's something fundamental you aren't understanding about enums

[fervent parcel]

yes this works unless you use serializedProperties

[misty glade]

you're treating them as ints - and they are, internally, but that should be opaque to you - you should be treating it as the value

what doesn't work about it?

SerializedProperties support enums just fine

including friendly display names, etc

[fervent parcel]

if it worked, I would have done it

or maybe I made a mistake

but if you can give me an example to try so I know

coz I been at this for 2 days lool

I swear I tried every combination I can think of

[misty glade]

this is what I'm trying [hard] to figure out, but it's hard without code or specific errors or .. what you're trying to achieve :p

I mean, enums are just... enums, you don't (in general) treat them as ints

[fervent parcel]

I am just changing the style of enum typed serialized property

[misty glade]

public enum DayType 
{
  Monday, // <-- don't treat this as "0", treat is as "DayType.Monday"
  Tuesday, 
}

[fervent parcel]

yes

that makes sense

let me try again

brb

[misty glade]

Also, no one here is going to take/steal your code (maybe they are, I dunno?) they're just interested in helping. Parse out the useful bits if you need to. Additionally, if you're just changing the style, then I'm assuming all you want to be doing is passing a different myEnumStyle to the method..

[fervent parcel]

its not my code

I dont care if it was mine lol

this script is 3k lines and I am just trying to change the style of it

I would have to ask them, but we are on different time zones

[misty glade]

    public enum MissionStateType // here's an example. I have a state Enum for "missions". Here's the declaration...
    {
        Awarded,
        Started,
        Complete
    }

    // and elsewhere in the codebase, where I display an object that needs this value:

                    if (CurrentState == MissionStateType.Started)
                    {
                        ActiveMissionPanel.SetActive(true);
                        NoMissionPanel.SetActive(false);
                        InProgressControls.SetActive(true);
                        PendingControls.SetActive(false);
                        CompleteControls.SetActive(false);
                    }

I don't do "if CurrentState == 1" or something like that

[fervent parcel]

ok

[misty glade]

And also, CurrentState is a "MissionStateType", not an int, so I never have to try to ... cast it back and forth to an int

[fervent parcel]

but in this editor script

everything is a serialized property

its not an explicit type

[misty glade]

I understand.. but I don't think you're understanding my question... wherever you consume the enum, you're .. doing something funny, but I don't know what since you won't show the code. 🙂

(It might not be your fault, maybe it's someone else in the company, but... just saying, there's something fundamentally wrong with your code/approach above)

gotta run sorry!

[fervent parcel]

the editor script is only changing selected enum, they consume the code in the target script and I dont need to deal with that part

well thanks for the help!

but this code only changes the selected state of the enum, I dont know why you care what they do once they change their states, it doesnt changed the posed question

and the selected state, its the selected state in the inspector

[jolly wave]

Hey guys, I probably dont belong in this chat, but the guys on beginner code told me to take it here, I got some issues returning a value from a cell in a mysql table into unity, anyone willing to help?

[sturdy edge]

you're being helped there.. I dont know why you posted your question there anyway. now you're just crossposting

[hallow cove]

what should I use interfaces for?

[fervent parcel]

Youtube it or google it

[hallow cove]

bruh

bruh

[hollow garden]

i mean it should be your first instinct to google smtn lol

although that's for java

but who cares

[sturdy edge]

Oh they crossposted. They were answered in general

[pale juniper]

hi guys i wrote a turret controller script and it has done its job great
now when i wanted to make an UI for it i have found a quite a bit of slop in it

my turretscript is basically not accurate enough or im screwin something up math wise when aiming the cannon at a point

basically what ends up happening is that the turret should rotate until the difference between its forward vector(red vector) and the reference vector(green vector) is 0 (then they should be the same)
but they are not, my turret stops a little earlyer than needed
https://paste.myst.rs/e7p88d40
and i dont know why,so feedback and tips on what am i doing wrong would be appreciated.

visual representation of the bug (output of Debug.DrawRays in PointAtTargetPoint())

[gray pulsar]

I'm on mobile, so it's hard to read the code well, but I noticed that in PointAtTargetPoint you use Turret.transform.position instead of Canon.position for setting one of the vectors.

[misty glade]

@pale juniper first thing first - you have a really sloppy coding style so it's making this hard to read/understand, so you really ought to spend a little bit of time cleaning up your codebase so things like this aren't problematic (for you!) in the future.

Specifically: Name your methods with verbs, and name them clearly what they are supposed to do. What is turretcontrol() doing?? I can't tell what your intent is from the method name alone (and in the future when you forget your own codebase - and you will - this might not be obvious to yourself). Is it aiming the turret (AimTurret())? Changing some aspect of the turret (SetTurretControlMode())? Moving the turret's aim direction toward some direction (RotateTurretOneTick())? It's hard to figure out what the problem is when we/I/you can't tell your intent from the naming convention. If you find yourself naming things like AimTurretThenRotateItThenSetTheAimMode() then you know you have methods that are doing too much, and bugs are going to be nightmarish to figure out).

Now on to the bug/issue itself - Without diving into your source code too deeply, I suspect that you've got the wrong location of one of your objects - double check your pivot/anchor/etc on the Cannon and Turret objects are .. correct - at least the same

You're also doing some.. stuff that I don't quite understand with your offsets:

      actualcamtransform = wgcam.camtransform;
      aimCorrectionfromcamera = actualcamtransform.InverseTransformPoint(transform.position).x; 
      offsetforturrets = wgcam.offsetforturrets;
      aimpointdistace = wgcam.aimpointdistace;

[paper nimbus]

Is it possible to get referece to button that was pressed by script thats attached as unity action on button?

[paper nimbus]

EventSystem.current.currentSelectedGameObject thats work for me 😛

[sly garden]

Can anyone help please?

[stable spear]

Quaternion.FromToRotation(Vector3.up, C.normalized);

[kindred tusk]

Can also just set transform.forward etc. to C

[stable spear]

ah, I didn't know that was settable

wait, how can that make sense

[kindred tusk]

I think it is like transform.rotation = Quaternion.LookRotation(value)

[stable spear]

there's not a unique rotation that sets a forward vector, but I guess it could just do the same thing as FromToRotation

[kindred tusk]

It's just like LookAt with the second argument set to Vector3.up

I think?

[stable spear]

ok, but that's exactly what he doesn't want

Can transform.up be set?

[kindred tusk]

https://github.com/Unity-Technologies/UnityCsReference/blob/61f92bd79ae862c4465d35270f9d1d57befd1761/Runtime/Transform/ScriptBindings/Transform.bindings.cs#L47-L54

It's exactly what you wrote, yeah.

[stable spear]

ah, so it works correctly if up is used

[kindred tusk]

But yeah, it's a handy shortcut

[cunning dirge]

Please, can anyone help me? How can I check if the player went to the site that a premium link shortener sends?

[kindred tusk]

That would be a question for your premium link shortener provider.

They should provide analytics. bit.ly does

Most likely it would be something like this: https://link.shortener/link-id?id=your-unique-user-id

[gaunt gate]

hi, i dont know where to post this but my unity froze when i pressed play and i didnt save in unity so i cant shut my pc down

[tropic lake]

you can save your scripts but any scene changes will probably be lost

what scripts have you written that could freeze unity?

[gaunt gate]

nothing big tbh

the last script i edited before the crash is nothing i havent done before

  public float travelSpeed;

    // Update is called once per frame
    void Update()
    {
        while(true)
        {
            transform.Translate(Vector3.right * travelSpeed * Time.deltaTime);
        } 
    }

[gaunt gate]

^

[tropic lake]

yikes

a while true will run infinitely

[gaunt gate]

thats what i want

[tropic lake]

yes but you've done it in update

and unity runs each frame on each mono sequentially

meaning you've halted the entire program

[gaunt gate]

oh...

[tropic lake]

if you want a while loop look into coroutines and yield return's
https://docs.unity3d.com/Manual/Coroutines.html

[gaunt gate]

ive never understood how these things actually work, i really should tho

[gaunt gate]

thanks

[hallow cove]

hello

I'm struggling to understand how I'm supposed to use state machines

our game is story driven and it starts off with some gameplay and cutscenes

[compact ingot]

who says you are supposed to use state machines? its certainly a good idea in places but there is no fixed rule... generally what you probably want is divide a system into mutually exclusive states to make transitions between those more explicit in a single place, in code. so for example you could have an init, menu, inventory, game, cutscene, death, gameover, ... state in your game manager and define what has to happen onEntry/Exit of those states and which from-to transition are allowed... a properly designed state machine would allow you to expressively define those transitions and actions and avoid most or all if/else or switch statements

[hallow cove]

beacuse they seem like they would make coding puzzles and everything a lot easier

I could trigger stuff based on a state

like, cameras for cinematics and stuff

you know?

[compact ingot]

yes, thats the point

[hallow cove]

so that's why I wanna use them, because they're simple to set up in my project so yeah

hmm

[compact ingot]

what is the question then? if you know what they are good for...

[hallow cove]

this is a multiplayer game so it's more complicated

I just need to know how to not under and over use them

do I use them for a lot of things like walking, running, jumping, shooting, reloading, what tab you have open in the inventory and settings menu

etc.

[compact ingot]

that really depends on the ceremony your FSM(s) require to be set up... if it makes code longer or more complicated or the thing isn't really a system... maybe not use them?

[hallow cove]

let's say I have the game start of as a cutscene, then change gameplay where the players can move, then short panning of the camera to attract the players' attention, more gameplay and then cinematic again

that would require

gameplay state

cinematic

and panning

[compact ingot]

Also if you have a lot of interdependent states that would cause state explosion... dont use them... hierarchical FSMs also get out of hand quickly. better use other models

[hallow cove]

and based on these I could enable and disable certain gameobjects

this would be the way to go, right?

[compact ingot]

that should probably two systems that interact via signals/events, not all one FSM

[hallow cove]

uhhhhhhhhh

why tho?

I'm sorry, I learn from examples best so please bare with me

[compact ingot]

you shouldn't use a FSM for something a timeline can do

[hallow cove]

it's like, if I enter a trigger, then I want that to change the state to a cinematic or something

or in case I wanna make a puzzle and have certain states I need the player to progress through

I just feel like it's way more simple to use it this way

[compact ingot]

yes, you have a FSM that handles the main game-states like cinematic, play, menu .... but you don't define what happens in any particular cinematic in THAT FSM, you use other ones or other types of abstractions for the gameplay, the cinematic and the menu... so: don't create one huge FSM, make separate ones and have them stay on one level of abstraction/organization

[hallow cove]

I know

what would a good system for that look like

I just need like, let's say a trigger

when you enter it it triggers the cinematic state

and in that state I want the player to look at something or get switched to a different scene, whatever

how could I make that modular?

[compact ingot]

each trigger -> cinematic -> optional-action could be one such module. that action at the end could trigger the next state-transition.

[hallow cove]

I could make a unity trigger or something-

and use the cinematic state for other scripts to like

just have a base script that tells you "Ok, you need to disable the player and stuff"

which'll happen every time the cinematic state starts

and then switch back to gameplay or something

[compact ingot]

that should be defined in the fsm-state

[hallow cove]

yes

I know

I can also use this for reloading and shooting in case I need that to do something

that's not overusing it, right?

the system I'm using is just a an enum of states and functions that are like

NameOfState_Method

[compact ingot]

overuse happens when you feel you don't understand whats going on anymore... then you introduce abstractions

[hallow cove]

and I can make it a void or IEnumerator

[hallow cove]

I see

can you explain to me what you mean by abstractions just so I can make sure I understand it well

I'm kinda sleepy sorry

[compact ingot]

example: a FSM is an explicit abstraction over code that uses if/else/switch to express the idea of a "state"

basically you build a higher level system that orchestrates more localized/detailed/lower systems and only deals with the interactions between those at the higher level

[hallow cove]

I think I get it-

[compact ingot]

abstraction can also mean that you encapsulate and hide a modules inner workings such that other parts of the larger system only interact with it through a simple public interface

[hallow cove]

I see

thanks!

[cunning dirge]

Thanks for your reply, you have revived my hopes. I'm going to ask bitly support and the shortener I was testing. Do you know other shorteners that allow you to check this in unity?

the problem is that I think bitly doesn't pay to go through my links. I'm looking for shorteners that give me money

[kindred tusk]

I don't really understand what you're looking for. Sounds like you want an ad network.

[cunning dirge]

I'm looking for a form of monetization that pays fast, I was blocked when I was about to withdraw the $100 and I don't want to risk going through it again

I haven't found ad networks with a low minimum payout, but link shorteners have several that pay when I get to $5

even if I pay little, it's worth it to me, when I'm earning more I'll use the ad networks

[hushed fable]

The secret is that the ad rates scale equally to the low minimum payouts 😛

[ember geyser]

CODE ORGANISATION QUESTION: In a big class I have lots of variants of ways to do things, as I determined how to do things in a complex little part of the project. Is it the done thing to duplicate the class with a version name, and prune it down to what's best, thereby keeping the original for reference/later consideration? Or do you simply clean up the original and discard all the various different ways iterated to eventual choices?

[tropic lake]

if you're refactoring it's best to retain the original yes

it may be bad but it works, and you'll probably need to reference it many times, even after you've finished refactoring it since issues can arise later on

i like to keep it in a separate folder in Unused Scripts for example and add Old at the beginning (you can even put it in a different namespace)

[sage radish]

Do you not use version control, like Git?

[tropic lake]

i do yeah

but i don't want to rollback when i can just click on a file

whatever works

[sage radish]

Most IDEs have a "compare with history" option, or you can look at the history on GitHub or wherever you host your repo.

[native hinge]

Can somebody give me a proper explanation of this operator? =>

[tropic lake]

have you googled it and read the many sites that explain it?

[native hinge]

yes

But I still don't understand it

[kindred tusk]

It's just syntactic sugar for a delegate.

If that doesn't answer your question you're probs in the wrong room.

[native hinge]

I kind of understand that

I understand using it like this void Start() => gameObject.SetActive(_active);

[sage radish]

Depends on where it's used. It's also used for expression bodies, to avoid braces in single statement methods:

public void Log() => Debug.Log("Hello world");

[native hinge]

But not like this SomeMethod(() => somethingElse);

[kindred tusk]

Ah, that's true.

https://www.tutorialsteacher.com/csharp/csharp-delegates

[kindred tusk]

It's creating a "first class" function that you can pass as an argument to another function as a callback.

[native hinge]

Soooo

It's calling a function, and the function's argument is another function?

[kindred tusk]

yep

@native hinge https://www.tutorialsteacher.com/csharp/csharp-delegates

[native hinge]

🤯

[kindred tusk]

Funception

[native hinge]

Not sure how that works but cool, thanks

Hello guys I am trying to swap 2D squares so that they are sorted according to their height. I am using bubble sort but the swapping is not correct. I suspect there are some wrong assumptions in how I swap my squares. Here is the code : https://hastepaste.com/view/gHKvaF0NB.

I posted this question in the beginner sections and 2D but no one answered it yet.

[kindred tusk]

I already answered you in #💻┃code-beginner

or somewhere

I've lost track with all your crossposting

#🖼️┃2d-tools

You don't need to write bubble sort

You can use List.Sort

[granite gust]

Hi. I upgraded my Unity to 20.3.20 and VS to the latest preview and suddenly my Newtonsoft.Json NuGet package got unusable.. IntelliSense wants me to use "Plastic" (what is this?) and even tho i can rebuild the solution in VS, Unity Compiler won't let me do anything as it is still missing the assembly

[ember geyser]

Something to avoid, at all costs! Almost all syntactic sugar in C# should be avoided. Gross generalisation. But truth 😉

[misty glade]

Huh?

[native hinge]

Alright

[stable spear]

@misty glade => makes a lambda function

[regal olive]

The idea is to use all various sorts such as merged sort, bubble sort, radix sort and etc 🙂 I do this do visualise all the algorithms 😛 I agree that you have a solution but the meaning of the 2D algorithm visualiser is to show the various sorting algorithms 🙂 @kindred tusk

[misty glade]

I know what it does, I use it every day. I'm curious about the advice not to use it.

I wrote one in the last ten minutes even..

            isgServerProcess.ErrorDataReceived += (sender, args) => { if (args.Data.Trim().Length > 0) e(args.Data); }; //soak empty errors

[stable spear]

The only time you should avoid it is in performance critical code that is run frequently (like Update()), because it allocates memory

[misty glade]

That's fair, but .. still, I believe the syntactic sugar in C# to be one of it's greatest strengths

[distant pivot]

I find stuff like => and ternary operators kind of harm readability (and not to mention the => operator looks like a comparison at first glance)

[stable spear]

I don't think => qualifies as syntactic sugar

[ember geyser]

Avoid delegates, virtuals, interfaces and Actions and Events. If you want fast and light. Syntactic sugar in C# is only a strength (at all) because the language is so old fashioned verbose.

[stable spear]

uh

[misty glade]

        private static Person GetCrewMember(Battle b, bool C1, int index) => (C1, index, index) switch
        {
            (true, 1, _) => b.C1Crew1,
            (true, 2, _) => b.C1Crew2,
            (true, 3, _) => b.C1Crew3,
            (false, 1, _) => b.C2Crew1,
            (false, 2, _) => b.C2Crew2,
            (false, 3, _) => b.C2Crew3,
            (_, _, _) => null,
        };

this would be like 30 lines of vertical vomit without this sugar

[stable spear]

that's like 75% of the language

[misty glade]

This is just .. terrible advice, sorry

[ember geyser]

I'd make a case that the explicitness of C# is its greatest strength, and the reason it's possible to use malloc and stackalloc within what is otherwise a messy OOP language.

[misty glade]

These opinions are 🤯

[stable spear]

that code seems to indicate some kind of bad design to begin with

[misty glade]

The naming convention of "1" "2" and "3" is misleading - they should be named "front" "middle" and "back"

[stable spear]

e.g. why are there are 6 variables instead of an array or list something

C1Crew1, C1Crew2, C1Crew3, etc.

[misty glade]

In this game, crew members have a "position" that have domain-specific logic

Think of position 1 as the captain - they have some bonuses, special game logic, etc

[stable spear]

So?

[misty glade]

It's not a variable-length array/datastructure, etc

[stable spear]

all these variables have the same type, Person

so Person[] will hold them

[ember geyser]

He's using tuples to generate a "truth" for a highly succinct but unreadable switch statement. I think.

[stable spear]

you can use an array without it being variable length. Sometimes just to make the code easier to write

[misty glade]

There's no reason to use an array here - the size of the data structure isn't variable, iterating over the array isn't something that happens, etc

[stable spear]

You should always try to make things uniform

Arrays achieve uniformity

Uniformity means you don't need cookie cutter code like GetCrewMember

[misty glade]

This is, for sure, a "denormalized" data structure, but it makes sense for this particular application

[stable spear]

I bet you've ended up writing almost all of your code 6x over for each variable

so the code is 6x bigger than it needs to be

[misty glade]

Er, no..?

[stable spear]

well, that sometimes happens

[ember geyser]

Thank you very much for this. This is my tendency, as a result of decades of iterating in design software, and a lifetime of writing of C before that. Just wasn't sure if it was still a thing. Glad it is! THANK YOU!!!

[tropic lake]

although as mentioned later version control also achieves this

up to what you prefer

[misty glade]

If I renamed the variables to something like this, this might make more sense:

        private static Person GetCrewMember(Battle b, bool C1, PositionEnum position => (C1, position, position) switch
        {
            (true, PositionEnum.Captain, _) => b.C1CrewCaptain,
            (true, PositionEnum.FirstOfficer, _) => b.C1CrewFirstOfficer,
            (true, PositionEnum.Engineer, _) => b.C1CrewEngineer,
            (false, PositionEnum.Captain, _) => b.C2CrewCaptain,
            (false, PositionEnum.FirstOfficer, _) => b.C2CrewFirstOfficer,
            (false, PositionEnum.Engineer, _) => b.C2CrewEngineer,
            (_, _, _) => null,
        };

[ember geyser]

I'm using version control but, like you, find it overkill (and a search nightmare) when trying to have a quick look at how I did something (an unknown time ago).

[stable spear]

why do you use the index / position twice?

[ember geyser]

Looks like he's saving it for something else, spacer, at the moment.

[misty glade]

Hard to explain in a nutshell but there's abilities that .. deflect the "active crew member" onto themselves

think "Taunt" in hearthstone

anyway, placeholder for the moment but it needs to be renamed for sure

anyway was just more commenting that this "simple" getter would be much larger vertically with a traditional if/else statement

[ember geyser]

@misty glade I think I get exactly what you're doing. Been down that road before.

I tend to (these days) use drop in state objects for this kind of thing, and call at them. And write verbose, so I don't need comments or my memory to work to understand what it does in 2 days time.

So where you're relying on => I'd wind up with a bunch of objects that descend from an abstract, each with the appropriate functions fleshed out.

[stable spear]

a simple 2D array would make GetCrewMember 1 line, and it has the bonus that you could add additional roles and crews with a single line change.

suppose in the future you want 3 crew rotations instead of 2, or you add another role

anyway, I give up. Some people really like repetitive inefficient code.

[misty glade]

there is a case to be made for engineering this "up" to be more extensible, but that's not on the radar in any near future

I hear what you're saying and don't disagree, but there's really no repetition in the codebase with respect to crew positions/etc

[ember geyser]

@stable spear you might undersstand what you mean, but until it's laid out, and provides the same insights and opportunities for expansion as tuples as state, it's difficult to comprehend how it's at all flexible in two arrays

But this is coming from someone that uses int4's for state, so ignore me!

[misty glade]

I just sort of fundamentally believe that something like:

LeftPlayerCrew[1]

is more error-prone or less obvious than

LeftPlayerFirstOfficer
// or
LeftPlayer.FirstOfficer

[stable spear]

You can use the enum as an index into the array

[misty glade]

and obviously I could put some sort of thing internally

public RoleEnum FirstOfficer {get _Crew[1]; set;}

but I don't think that's the solution either

[urban warren]

I haven't been following along so maybe ignore me, but isn't this just a dictionary with more steps?

[ember geyser]

@misty glade keep going with the (stateABC, stateXYZ, stateUVW) until its evolved and you realise the best other way to do it. Eventually the best way will reveal itself.

It's ok - the discussion was about c# syntactic sugar, I posted a code snippet, and the conversation veered into a code/architecture review of my snippet. 🙂

I'm pretty happy with my architecture as it stands.. I'd post some videos of gameplay but .. the developer art is embarassingly bad :]

[ember geyser]

I want to push towards state objects so that you can replace => with a . 😉

[urban warren]

LOL, tbh I would expect no less for #archived-code-advanced, haha.

[misty glade]

It's ok, I actually don't mind. "holy wars" are filled with strong opinions because.. those opinions come from people who have enough experience to make valid comments with experience to back it up. They're usually solid, too. The longer I write code and architect systems, the more I realize the less I know.

(and I've been doing it since about 1997)

(poorly, sometimes!)

I think the important bit once you know what The Right Way is to do something, when to break that and "denormalize" something, or when to unbreak it when you inherit some shitty codebase (and when that work isn't worth the payoff).

From my testing: Unity and C# can inline/optimise abstracts to almost as fast as direct calls, much more performantly than virtual calls (which Unity is slowly making a bit faster) and WAY faster than interface calls, which aren't optimised much, if at all.

if we‘re not ‚allowed‘ to use sugar/abstractions or lambdas and hide in terror from the GC, there is no point in using C# or unity.

[native hinge]

my brain... hurts...

useSprint ? (Input.GetButton(sprintButtonName) ? walkSpeed * sprintMultiplier : walkSpeed) : walkSpeed

double ternary

🤯

[compact ingot]

Formatting is everything with nested ternaries

[native hinge]

Could a ternary theoretically be endless?

Or is it limited to an amount of nested ternaries?

[compact ingot]

Probably limited, but likely sooner limited by confusion of the programmer

[native hinge]

Ok

[urban warren]

Yeah, I rarely use nested ternaries because they get sooo much harder to read then just one, or an if. At least imo.

[compact ingot]

they are an indication that the author doesn’t like other people much 😉

[urban warren]

Very true. On rare occasion it will look okay, but the vast majority of the time it is better to just use an if statement.

[compact ingot]

I‘m waiting for n-ary in-line switch syntax with pattern matching C#8 🤙

[cedar ledge]

why is RequireComponent(typeof(Rigidbody2D)) getting rid of the kinematic rigidbody and replacing it with a default one?

[native hinge]

Quadruple ternary...

float speed = useWalk ? (useSprint ? (Input.GetButton(sprintButtonName) ? walkSpeed * sprintMultiplier : walkSpeed) : walkSpeed) : (useSprint ? walkSpeed * sprintMultiplier : 0f);

So confusing

But I also don't want 200 IFs

[misty glade]

I mean it's nice to cram into one line, but this seems like it's going to be really hard to debug mentally..

Could you maybe do something like starting with 0f and adding a walkspeed or sprintspeed?

[orchid marsh]

You're overcomplicating things. Ternary: Use Sprint && Get Button ? Sprint Speed : Walk Speed.
Use the && operator

[misty glade]

float _speed = walkSpeed;
bool _useSprint = (useSprint || Input.GetButton(sprintButtonName));
if (_useSprint) _speed *= sprintMultiplier;

even simpler

I'm not quite sure if I'm replicating your logic above.. not sure what "useSprint" is, I'm assuming something that makes the player sprint even if they're not pressing the sprint button?
