I've already solved it. Now I decide how to save the value of the selected language.

[undone coral]

you can use player prefs

use mudbun or clayxels for this kind of stuff

don't create your own geometry engine

you can also use Realtime CSG if you want a free asset

realtime CSG supports calculating a BSP-style enclosed space

it's a little shaky what you're trying to say though

it sounds like you haven't decided what exactly players will do. i'd suggest looking at that steam game with the siege engines

Good morning, I need help with Editor Code, How do I register, a mouse over event? for example, when you mouse over a button, it lights up even without you clicking them. I can change the styles of how that displayed, but what I am interested in, is registering to such an event, including when the highlight turns off when you no longer mouse over.

this is all in relation to editor GUI

not sure if this is considered advance

Mesh Vertex Color getting stripped after compiling to AssetBundles, and using it for a shader.

How do I force the vertex color to stay?
Already tried enabling R/W

2020.1.17f1

[sage radish]

There's an option for that in Player Settings.
https://docs.unity3d.com/ScriptReference/PlayerSettings-stripUnusedMeshComponents.html

It's called "Optimize Mesh Data" in the editor

[tender mango]

Has anyone switched to 2021.2 yet? I'm getting "Unexpected node type." errors when building, playing in editor, or compiling scripts. The errors during building cause the build process to fail.

[novel birch]

Yeah we looked at this solution and it simply tanks our performance/memory due to this affecting ALL meshes (To completely unstable levels). We just need it for this mesh.

[sage radish]

I can only think of a dirty hack, which would be to make a prefab with this mesh and uses material that uses a shader that reads vertex colors, and either reference prefab that in some scene somewhere or put it in a Resources folder so it's included in the build. That will make Unity think this mesh can't have its vertex colors stripped.

[worthy lodge]

I made a class inherit from Component, but cannot add it to a gameobject

public class HackableObject : Component
{
    public Action[] Action { get; private set; }

    public void DoThing()
    {
            //dothing
    }
}```

I get the error it has to derive from MonoBehavior, but I thought Component also could be added to a gameObject

[stable spear]

the message is clear, why are you asking?

[worthy lodge]

Yeah I know it can be fixed by changing it to Monobehavior, but why cant you add a Component as, well, component

[stable spear]

because Component doesn't implement all the expected behaviors of a custom script class? it's just designed to be the base class

I would guess there are non-script internal components which implement something other than Monobehaviour, but I haven't looked too closely at it

Transform for example, is a Component but not a Monobehaviour

[junior sorrel]

Hello
I want to know if there's a way to create like a continuous integration for Android/IOS builds
It's my first doing any continuous integration so if there's an example project on github or any tutorial can you share it with me please?

[novel birch]

Many options;

You can use solution made by Game CI:
https://github.com/game-ci/unity-builder

Otherwise there is also Unity hosted one if you have Unity Pro/Enterprise
https://unity.com/products/unity-build-server

Or you can use your own homebrewed solution using something like CircleCI/Jenkins/Github Actions, together with running Unity in Batch mode.
This requires a lot of boilerplate though...
I would simply start by learning how to start by making a batch script that does the build for you and then slowly move that to into a CI system. And then from there build auto pulling from your version control. Etc. etc.

[novel birch]

Yeah I was going into those solutions as well. Currently just taking this specific mesh out of the AssetBundle. Will investigate this later!
Thanks 🙂

[golden oriole]

Hello, I have a project I'm working on that involves a data type that has two different human-readable interpretations. One is the base value, and the other is a stringified representation, kind of like this:

MySpecialType x = 1
((int)x).toString() //1
(string)x //"one"

I have implicit operators to convert between my primitive types, and would like an inspector that would allow me to edit either the string value or the int value, and adjust the other one while it's being set.

It's a struct, and I'd really like to keep my base classes as separated from unity's wrappers as possible, so I've created a PersistedMySpecialType that I can instantiate as a prefab, and it has a string field, and I've been able to mostly get the inspector working as I'd like, but I'd really prefer it be a property drawer so I can edit the persisted instantiation inline. Does anyone know if there's a way to associate two input fields to a common base field through a property drawer?
If I make the PersistedMySpecialType extend UnityEngine.Object, I'd have to start instantiating a prefab for every single one, and there's going to be literally hundreds. If I don't make it extend UnityEngine.Object, I can't get Unity to access it.

Here's my two prefab-based classes:

    public class PersistedMySpecialTypeList : ScriptableObject
    {
        public List<PersistedMySpecialType> MySpecials;
    }

    [Serializable]
    public class PersistedMySpecialType
    {
        public string foo;
    }```

The image attached is as close of an attempt as I've been able to accomplish so far, and uses the inspector on the `PersistedMySpecialTypeList `

Guys I was wondering if it is possible to edit memory using unity

like Allocate Memory
Free Memory
Protect Memory
Read Memory
Write Memory

[stable spear]

uh, what are you trying to do?

[golden oriole]

I don't think you can explicitly set memory targets, and I don't think you'd really want to anyway. Closest I could think of is you could allocate byte[] and store things in there, or allocate pointers.

[tribal willow]

Just wondering if it is possible. I just had a game idea

[stable spear]

I don't see how a game idea would lead you to those

obviously you can allocate, read, write, and free memory.

[tribal willow]

I'm just trying to come up with different game idea

I wanna be different

What's so dangerous about that. Reading my own game memory isn't dangerous

[stable spear]

If by Protect you mean, protect in the page protection sense, you probably could, but why?

[tribal willow]

how is Void Start() initialization if Initialization gives a variable an initial value at the point when it is created 😩😩

[stable spear]

what??

[tribal willow]

give me sec

[stable spear]

public class Foo {
  int x = 5; // this is initialization
  Foo() {
    x = 10; // this is assignment in the constructor
  }
}

[stable spear]

Start() is called right before the first frame is going to be produced, so it happens even later than Awake or construction

what is the goal of setting tree?

transform.gameObject is just the current gameObject

you shouldn't need to store that

[tribal willow]

Oh so start is called before that healthis created

[stable spear]

no

[tribal willow]

Initialization gives a variable an initial value at the point when it is created

[stable spear]

What are you trying to do?

[tribal willow]

I'm wondering how Start is initialization

[devout hare]

Technically setting field values in Start is assignment, but it's called initialization because in practice that's what it is

[tribal willow]

thx

Assignment gives a variable a value at some point after the variable is created.

[tribal willow]

i love u

[golden oriole]

intialization is telling the computer a variable exists:
string x;
assignment is giving that variable a value:
x = "hello";
Initialization and assignment:
string x = "hello";

[tribal willow]

My head was gonna explode

[stable spear]

Member variable Initialization ---> Constructor --> Awake --> OnEnable --> Start --> Update

[hard lily]

There is a reason some games use something like void Initialize() {} and set up all the variables in there

And yeah, even though it's technically assignment it's also the "game" initialization

[tribal willow]

umm make seense

[tribal willow]

but Initialization = gives a variable an initial value at the point when it is created.

[devout hare]

right, you can think of the word "initialization" having two distinct meanings, one for the technical variable initialization and one for the game initialization

so in Start you initialize variables by assigning values to them

[tribal willow]

ow 😋 thank you so much you guys are so helpful

[hard lily]

Think of it like English language vs programming terms, which of the two the person was trying to use is up to context

[tribal willow]

include in c++ and using in c# are they the same

Because #include copies code and paste

Does using also copy code from the file and paste it

if you can make sense of the low-level code on the right side, you will understand everything 😄

[undone coral]

what's your objective? why do you have a data type like this?

[tribal willow]

Where can I learn low level code

I know it's like ultimately helpful

[hard lily]

Go learn assembly

[tribal willow]

thx

[tribal willow]

do u speak assembly

[stable spear]

https://en.wikipedia.org/wiki/Common_Intermediate_Language

[undone coral]

like why would someone using unity, a programming environment, ever need to write "three" instead of 3?

[hard lily]

Nope, I understand it but I don't think in assembly, I think in C# D:

[undone coral]

in the inspector?

[tribal willow]

yeah

[undone coral]

if someone has to do that, that someone should throw their computer away and use a loom

[tribal willow]

i'm gonna buy course for assembly

[undone coral]

your inspector should just be the integer value 3

That is a challenge in https://projecteuler.net/

[regal olive]

I already asked this question yesterday and I thought I understood, but I didn't... I don't know how to call the exampleFunction(); from the exampleClass without the direct reference. Currently I'm creating the moddingAPI class library (.NET Framework if this is important) so it's basically a new project without anything imported, and I don't know how to get the reference to the exampleClass. I hope you can see my problem.

[undone coral]

your objective is to make your game moddable?

[regal olive]

Yes sir

[undone coral]

what kind of game is it

[regal olive]

2D

[undone coral]

what do you do in it i mean?

what would players mod?

i vaguely recall you received some bad advice

are there any existing players?

[regal olive]

uh yes, they can import custom tilemaps, spritesheets, just the whole game open to them

[undone coral]

and is this windows only? PC only?

[regal olive]

Only PC yes

[undone coral]

import custom tilemaps... built in unity, or externally?

windows and macOS or just windows?

[regal olive]

built in unity

windows, but maybe mac soon idk

[undone coral]

so players are expected to add unity assets to your closed source binary game?

have you ever tried modding Cities Skylines?

[regal olive]

Yes have seen their modding api too, but didn't really try to mod it

[fervent sage]

Little confused about Vsync and lowering FPS on android. Apparently you cannot turn Vsync off on Ios Android, but according to the docs, if Vsync is on then targetFrameRate is ignored. So how do I set the framerate to 30 FPS on android if I cannot turn off Vsync and targetFrameRate is ignored?

[golden oriole]

I've abstracted down the problem quite a bit because I didn't want to explain the full thing... but since you asked:

I'm using a string encoded (and very lightweight encrypted) encoding of a float that gives me lossless storage of Vector2 values, including a parity. I am storing the vector2 values, but because of the nature of float values (3.2 can have several different bytewise representations in floats), I want to be able to either write the encoded value or the raw value in my inputs.

So, to my point, the implicit operator calls my encoding to allow me to more easily handle them for file IO and for math operations without needing to make the intermediary calls to do the encode/decode every time. I'd like to be able to write the encoded OR decoded values in the inspector to edit the underlying value.

[undone coral]

okay so i think this is probably going to be too challenging for you. have you looked at the uMod asset store asset?

you're not going to have a working thing for months, you're going to be reinventing umod

or you're going to be one of those toxic people who says they have something working when they don't

in a chatroom or whatever

i think you should use umod

[regal olive]

oh no, I want to code my own stuff, the thing is, I already know how to approach this, but I don't know how I can call the function without the direct reference

[undone coral]

why would you ever need to enter this weird encoding in the editor?

why don't you just edit the real vector3 in the editor, and expose the encoded version as a property?

are you trying to protect your game assets this way?

[undone coral]

like what's the objective

i don't think the implementation matters so much since it doesn't make sense at the moment

were you talking about making a cookie clicker game a while ago or something

[undone coral]

okay well you should download the umod asset then and at least look at how it does things

that will be the best learning for you

[golden oriole]

The objective is I'd like to be able to modify either one of the input fields for the interpretations of my underlying value, and have the other input field immediately reflect that result.

[undone coral]

no i get it

i mean why

you're being really shy about saying why

usually that means you already know it makes no sense 🙂

[golden oriole]

The Vector2 is used as seed data for a Random, and I want consistent results.

[undone coral]

okay well i have your answer, but you gotta tell me what you are trying to do

then i will tell it to you

it was like 30s of googling

like what's going on with this data structure, why do you need it

[undone coral]

this doesn't really tell me anything

[CustomPropertyDrawer(typeof(CustomStruct))]
public class CustomStructDrawer : PropertyDrawer { ... }

lets you define a custom inspector view for your struct

you can make it behave however you want

i think this is a bad idea though

because your struct makes no sense

and as a rule i don't help people who are trying to do stuff that makes no sense

there's an example of a custom property drawer here: https://stackoverflow.com/questions/54748945/unity-custom-drawing-of-a-struct-in-the-inspector

you can use it to write whatever you want, however you want

if you want to immediately update the other value go ahead and do that

[golden oriole]

Because I'm trying to make Random more deterministic, and I'm using the object's point in space as its seed because then I have a single point that controls both appearance and its point, so as long as that thing is at that exact point, it'll look the exact same. I'm making a solar system simulator, and these vector2s control my initial conditions.

[undone coral]

okay, but then you have no need for a weird struct

it isn't clear to me at all why you would need this

[golden oriole]

Flatfile storage of vector2s is inconsistent.

[undone coral]

if you need to store something... store it?

void Save(Vector3 someVector) {
  var valueToSave = CreateWeirdValue(someVector);
  // write value to save??
}

i don't know, what is going on here

you can store vector2 floats by writing them, and it will be perfect

on all platforms?

of course you can store floats

what are you trying to do...

[golden oriole]

I also want these to be user-sharable, and sharing exact floating points won't guarantee the same results, and the location is an important piece of that information, this contains it all in one place.

Point is, I have two different ways of viewing the same data. You could pretend it's a Date for all I care. Humans don't really understand 1636660701295, so if you're storing that, it'd be nice to be able to edit November 11, 2011 3:58:23pm instead.

[undone coral]

are you saying a vector2 from the editor?

if you are concerned about stuff like that, maybe use a vector2int instead?

and if you need a "floating point" value for it, you can just... divide or multiple it or whatever?

why would an end user need the unity inspector to behave a certain way?

are you trying to procedurally generate content in editor?

if you need stateful random, use XORShiftRandom, which is implemented easily

are you trying to do a behavior like the slipways world selector?

[golden oriole]

They don't, that's the point of what I'm getting at. I need this capacity, and the end user does not, otherwise I wouldn't have it in the inspector.

are you trying to procedurally generate content in editor?
Some of it, but only the initial seed conditions, and I want the seeds to be easily rebuildable.

[undone coral]

i think you are really overthinking this

are you trying to do this?

like some string representation of the seed?

[golden oriole]

Analogous to that, yeah.

[undone coral]

and then the user can select something on the map?

well do you think the slipways guy does something weird like a union struct

this is a unity game

what do you think is going on here? do you think you can put the mouse down in the same location and get the same seed?

is that important to your game for real, or not?

i think it's as simple as

ulong ToSeed(Vector3 worldPosition) {
  Vector2Int finiteLocation = SomeArithmetic(worldPosition);
  return (ulong)finiteLocation.x << 32 + finiteLocation.y;
}

is this helpful?

you're way overthinking this

then

String ToUserRepresentationOfSeed(ulong seed);
ulong ToSeed(String userRepresentation);

and seriously don't overthink it, it's just cosmetic

you never need to store the user representation

if you want to make it work in editor, do not custom property drawer a seed

[golden oriole]

you're starting to catch on to what I'm trying to do.

[undone coral]

create an editor window that just lets you translate it

don't create a Seed struct

just make an editor window with a number field and a translate button

and another string field with a translate button

[golden oriole]

Okay, so you don't know how then. Thanks for your time anyway.

[undone coral]

no i do, it's with the property drawer

it just doesn't make sense to have a Seed struct 😢

i showed it to you

anyway, i tried

[fervent sage]

Is there a simple way to tell if there has been any player input in the last frame?

^I have been using OnGUI but apparently you shouldn't use that

[undone coral]

what's your objective?

with Input System and EventSystem, yes

[fervent sage]

Just do actions in responce to input

[undone coral]

with Input, no

not easy

[fervent sage]

hmm

[undone coral]

Input is dead

i can tell already you are reinventing EventSystem and Input System

based on the question

[fervent sage]

Is there a simple way I can use EventSystem to do this?

[undone coral]

"i want to detect if the user is idle" or "i want to know if they should deselect"" or...

it depends

[fervent sage]

i want to detect if the user is idle is also what I want to do

[undone coral]

event system doesn't do keyboard

Input System answers this question exactly, for all kinds of user inputs

[fervent sage]

my game is a card game, and everything works just with regular input, including android IOS etc, I don't want to have to re-learn a whole new thingo just to check if someone is idle

[undone coral]

oh yeah

go for it then, test every known way you will input with Input

[fervent sage]

Well that's why im asking if there is a way; so the answer is no?

[undone coral]

no 😦

[fervent sage]

.>

[golden oriole]

@fervent sage this may be helpful. I have a similar use case where I didn't want to write a massive switch block for several user inputs, I just wanted to get whichever one they pushed down.

        {
            int? result = null;

            for(int x = 0; x < inputs.Length; x++)
            {
                if(GetButtonDown(inputs[x]))
                {
                    result = x;
                    break;
                }
            }

            return result;
        }```
That, combined with `Input.GetAxis("Mouse X")` and `Input.GetAxis("Mouse Y")` should be able to tell you what you want to know to figure out if a user's idle.

[fervent sage]

running that each frame is gonna be intensive, my primary objective was to get a notification on user input, which this kinda defeats the purpose. Probably best just to learn the new input system for me
Thanks tho

[sly grove]

It's actually not that bad tbh

[fervent sage]

Hmm, thinking about it, the only time I want to know if I'm idle is on android actually, and then the only inputs are touch, I can probably just check touches...

[sly grove]

Also if you really only want any input you can do Input.anyKeyDown

or check touchcount yes

[fervent sage]

Aha! that's what I was looking for! I still would need the mouse to check tho

[sly grove]

I think it checks for mouse clicks too

try it out

[fervent sage]

I need to check for mouse movement, but yeah I will thanks

[fervent sage]

Lastly, is there any recommendation on putting this anywhere other than Update? - I assumed OnGUI() was "when you get user input" but apparently this is not true

[golden oriole]

As long as you stay in the hundreds of things iterated per frame, you generally won't suffer a performance hit.

[sly grove]

OnGUI is where you read Events. Input.XXX should be read in Update

[fervent sage]

Ok thanks

Thanks all of you

[sly grove]

e.g. https://docs.unity3d.com/ScriptReference/Event-current.html

[undone coral]

OnGUI is for the deprecated immediate mode UI system

i wouldn't touch it at all

[fervent sage]

uhu

[misty glade]

Asked in C# discord without much response.. Hope this isn't too off-topic.

I'm designing my handshake process for networking in my multiplayer game, but I'm not super familiar with best practices for this workflow. Anyone know what I could google or read up on to learn this? My current approach is:

1. Client makes connection to server (hashcash required)
2. Server adds un-authenticated connect to pool of connections, waits for client to send credentials (this is a problem currently, no TTL on the pool so malicious users could make many connections to soak resources).
3. Client sends credentials to server.
4. Server authenticates credentials/user/etc and either disconnects user with a reason code or adds the user to the authenticated connections data structure.
5. Client begins gameplay.

But I have no idea if the above ^ is good, and don't really know what to search for to learn.

[stable spear]

What's your threat model here? Are you expecting to be DoS'd ?

Do you prevent them from re-using the hashcash?

[misty glade]

Potentially? I mean, I don't expect it but I'm not really sure how to prevent it. Hashcash is the DoS protection - but I don't currently disconnect un-authenticated users (since ... I'm not sure what the plan is there.. like, should I wait until the user on the client has entered their credentials before letting them connect, and immediately request credentials from the server, and disconnect them if they haven't provided them within 5-10 sec?)

[stable spear]

I know Linux has a limited number of sockets, which could be exhausted just by having too many open connections. Windows probably has similar limits.

[misty glade]

Yes - I believe the number of sockets is pretty big, though- hopefully not a problem early on, but I'm building the server in such a way that we can scale it horizontally if needed

But I mean, essentially right now I don't know how to .. uhm... start/submit/collect authentication points - ie, I can prompt the user for username and password as cleartext strings, but then what?

[sly grove]

Wow just learned about HashCash now. Seems cool

[misty glade]

(and what do I store on the server? username can be cleartext but .. password? no idea)

[stable spear]

the direct predecessor of Bitcoin

[misty glade]

Yeah, HashCash is 🤯 cool

[golden oriole]

private/public key would be a good way to do this. Public key encrypts, transmit to server, private key decrypts.

[misty glade]

But.. I don't need to decrypt the password, right? In fact, I don't even want to have access to that?

[golden oriole]

One way encryption. password->Hash(password) == storedPasswordHash?

[sly grove]

yep thjis is pretty standard -but you also want to salt it

[misty glade]

Just using default Object.Hash? do I need to salt it or anything?

[sly grove]

So in your DB you store this:
User:

• username
• salt
• hashedPw

[misty glade]

And... what do I salt it with? A fixed value of some sort..?

[golden oriole]

Yes salt yes use special hashing, and make it proprietary and unique.

[misty glade]

Sorry - these questions feel super basic

[golden oriole]

Salting can be done a number of ways. Multiply by some number, split strings, replace a character with another (careful with that one), add something to it, etc.

[sly grove]

When the user sets the password initially, you generate a random salt, then append the salt to the password and hash it, and store that hashed password and the cleartext salt

[misty glade]

So the salt is embedded in the client, right? client prompts user for password, client hashes & salts entered value, sends this string to the server, server stores it (at user creation) and compares it against authentication requests in the future

hm, ok

[sly grove]

then when you receive a login you append the saved cleartext salt to the incoming password, hash it, and compare to the hashed password in the DB

server salts

always

client never sees the salt

[misty glade]

so wait.. the client submits cleartext password to the server? (it's encrypted so that's ok, not worried about man in the middle attack)

[sly grove]

otherwise the client would need to know the salt if they switched devices

[sly grove]

yes the server gets the password in cleartext after decrypting TLS

[golden oriole]

If you want your client to encrypt it, I'd recommend using a secure connection protocol and let the transmission layer handle it (e.g. handled by SSL/TLS/HTTPS and not you)

[stable spear]

There's a way to avoid sending the plaintext password at all, but it's overkill

[misty glade]

ok, so the server hashes, salts, stores the value

[sly grove]

It should never be logged or stored anywhere other than in memory for as long as it takes to hash it

[misty glade]

right

[stable spear]

The #1 rule of secure login and authentication is not to roll it yourself

Surely there must be an existing system

[misty glade]

ok so.. high level recap:

new account: user enters password -> client encrypts packets -> client sends to server -> server decrypts password (in memory) -> server hashes, salts, stores in DB

auth request: user enters password -> client encrypts packets -> client sends to server -> server decrypts password (in memory) -> server hashes, salts, compares against stored value in DB

[misty glade]

yeah i really don't want to do this myself, but I haven't been able to find what i'm looking for

[sly grove]

There's existing protocols and techniques but it's inevitably somewhat bespoke to your given server application

[golden oriole]

server decrypts packets*, being slightly pedantic

[misty glade]

right, thanks

[sly grove]

more or less - yes. The encrypting and sending and decrypting part is generally done somewhat automatically by TLS, assuming you're using HTTPS for all of this

[misty glade]

so I have all the encrypt/decrypt working, but now i have this plaintext password (in memory) on the server and just have to figure out how to deal with it.. i sort of didn't want to roll my own but i went down the rabbit hole of learning about EAP and MsCHAPV2 and stuff and ... just got demoralized at trying to duplicate this

[sly grove]

In Java we used the BCrypt library for the salting/hashing

[misty glade]

I'm using Ruffles rUDP which handles it for me.. i'd have to dig to see what it's using under the hood

is there no .NET hash/salt/etc library? I've read that I'm not supposed to use SecureString anymore, and don't really know how to develop a secure salt algorithm.. I mean, I'm sure I can google that aspect up but I'm sort of new to this uh.. space? concern? area?

[golden oriole]

Easiest way to salt would be something like string hashedAndSalted = Hash(password + "SUP3RS@LTY")

[misty glade]

So I don't wanna fuck it up, even if it is only for a video game 🙂

[misty glade]

Ah, right.. that makes sense.. and I suppose I could make a reasonably long salt string and just keep it somewhere safe

env variable on the server or whatever

[golden oriole]

I'd recommend not storing it in version control, use a server config and keep it in a special hard-to-reach place.

[sly grove]

We generated a random unique salt every time the user set the password and stored it in the DB next to the hashed pw

[misty glade]

I am vaguely aware of how to rotate them as well - ie, have two salts, a primary and a secondary, try both, rotate to the secondary every few months, then back to the primary or something, and whenever a successful login comes in on either, re-compute the other

[sly grove]

so each password has its own salt

You probably don't want the same salt for all the PWs

that means someone could build a single rainbow table for your whole DB if it leaks

[misty glade]

Hm, ok, that's an idea too.. so even if the algorithm is compromised, you still can't brute force

[sly grove]

and get most of the passwords

If each PW has its own unique salt you need a whole rainbow table for each password

which is not practical

[stable spear]

I know there's a trick used in cryptocurrencies (using a nice property of elliptic curves) to be able to send a fingerprint of secret data (e.g. a password), with a challenge-response mechanism to be able to send evidence that you have that secret data, without ever passing the secret data to the server. Is there any common usage of this pattern in password authentication systems?

[misty glade]

I think I'm reasonably secure (said every CTO ever) - VPN access only to database, rotating primary/secondary API key for database, cloud DB (let microsoft handle all that patching nonsense), encrypted network traffic, hashcash connection challenge..

[stable spear]

actually, hm..

[sly grove]

Yeah this is how asymmetric encryption works, like Diffie-Hellman that TLS uses

or just public/privat key encryption

not sure which is more like what you're saying

[golden oriole]

Make sure your table/db is encrypted, too. That should also be handled by whoever manages your db.

[misty glade]

yeah, it's cosmos db, so that's all native

[stable spear]

well yea. I guess you could generate a private key based on the password.

[sly grove]

ALso yes this is how those like rolling code RSA devices work. Given a timestamp and your secret key, you generate a token, the server does the same, and if they match the server knows you have the secret key

[misty glade]

https://docs.microsoft.com/en-us/azure/cosmos-db/database-security?tabs=sql-api

[misty glade]

I'll have to read up on this.. do you know what this algorithm/process/tech is called?

[golden oriole]

Even if it is for a video game, you're handling data sacrosanct to the user, and should treat it with the utmost of care even if they don't. I'd even be taking similar measures to secure emails (if you collect them).

[shadow seal]

Especially considering the UK and EU's GDPR nightmare

[misty glade]

Yeah, I will be.

[shadow seal]

Say hello to 5 million euro fines

[sly grove]

By this point the user is an idiot if they're not using a password manager with random unique passwords, but yes this.

[misty glade]

I think I'm more concerned about preventing cheating (vs hacking). Botting or autoclickers or what have you. I have some ideas, but .. overall it's a little daunting.

[sly grove]

We cater to the idiot users as well as the clever ones

[stable spear]

it's not really directly related, but the mechanism I'm thinking of is basically Hierarchical Deterministic Wallets + ECDSA

[shadow seal]

Because the idiot users may be idiots, but are still protected by law

[misty glade]

This is actually another small problem - my approach currently requires me to handle the password directly in the client, meaning... I have to think about ways to not let a compromised device compromise the client's password inadvertently, while still allowing sign-in to be relatively painless

[misty glade]

thanks I'll look it up

[sly grove]

You shouldn't store the password on the client

[misty glade]

Prompt them every time they need to login..?

[sly grove]

the result of this whole authentication scheme should be the server sends the user back a temporary auth token.

[misty glade]

Ahhhhhhhhhhhhh

right

[sly grove]

That auth token can be used to authenticate any further requests until it expires

[misty glade]

And it's good for x hours

[sly grove]

yea

[golden oriole]

You may want to look into JWT/OAuth if you pursue this model.

[sly grove]

so if that's lost, worst case scenario the attacker gets to use it for some hours, but the password is not compromised

[misty glade]

Right - so the "password" box will show like a bunch of asterisks (if the token is still good) but never actually be editable

[sly grove]

sure, or don't even show a login page, jump straight to the action

if you have a good token

[misty glade]

And if the user logs in using that token, they get a free refresh .. and I suppose I could hard-invalidate it every few weeks or something

Right, even better. Awesome.

Y'all are smart people.

❤️

[golden oriole]

shoulders of giants.

[sly grove]

I did get paid to do exactly this professionally for a few years 😛

[misty glade]

I do want to eventually implement OAuth and SSO using other providers but ... I haven't found a library that offers this that supports windows/android/ios yet - even the Google Firebase one doesn't. I'm worried I'm going to have to roll my own here, eventually, too

[stable spear]

what went wrong? 😆

[sly grove]

My whole password database got compromised!
😛
I kid, I just moved onto other features

[misty glade]

haha

[stable spear]

PraetorBlue was Captain of his industry.... until he took an arrow to the knee

[misty glade]

I'm actually in the middle of a mid-life-crisis, thinking about moving into game development full time. I work at a public sector job now where I'm surrounded by zombies just clocking in/out every day and ... man, I hate it. I look forward to writing code every day, more than any other job I've held in IT in the past - and I've done pretty much everything .. product management, project management, CTO/CEO, QA, customer support even.. All I want to do is fix bugs and write code.

[stable spear]

welcome to the club

[sly grove]

haha yep. I was on the management track for a bit. Just meetings and performance reviews and project planning all day.

Had to step down from that role and go back to IC

It's soul sucking

[misty glade]

Hard to walk away from the benefits.. but .. yeah, I just can't stand it anymore..

Soul sucking is a phrase i've used about 600 times in the past two weeks in conversations with friends and family

Anyway, back to the code. 🙂

[golden oriole]

I'm working in game dev for a similar reason... help keeps the edge sharp. I may do some weird stuff (@undone coral ran into that), but most of the time it's to help keep me on my game.

[regal flare]

I was trying to implement a fog of war minimap for my game, and I was almost there but Unity keeps throwing some really weird behavior on me (more info in #archived-urp channel, one of the latest posts). So, if I can't go through, I'll go around. Do you guys know of any way to implement fog of war other than using non-clearing camera, render texture and alpha-inverting shader? Any other variations or alternatives?

[snow grotto]

You mean just a minimap with a limited vision? like having a radial gradient around it?

[velvet kettle]

Hello, can someone help me why the billets are going through the walls? I have rigid body ticked.

I want to stop the bullet when it hits the wall

Thank you in advance

[zenith ginkgo]

Are you on the 2021 tech release unity version?

[lofty inlet]

Does anyone know how I can implement in-app purchases that are compatible with Steam? Any video tutorials would be awesome. I can't seem to find any on Youtube

[leaden jungle]

just destroy them when they hit the wall, or rather you will probably want to disable them and add them to a object pool. Alternatively you could remove bullets altogether and use rays as many shooters do.

if you mean the bullets go through the wall without a collision being detected then it means your bullets are too fast. Checking continuous collision detection might fix the problem, but it is costly, you can slow down your bullets, increase your collider sizes, or use rays on your bullets. This isn't really an advanced code problem tho..

[mighty latch]

How does the Event system handle graphic raycasters? if you have multiple canvas (and multiple graphic raycasters, which one does it uses, if any?

Situation 1 : Get the current PointerEventData, in Update(), loop through each element in the "hovered" stack and print each of their name. Result: Any element present under the mouse position is correctly placed under the hovered stack, whether it lies in the global Screenspace Canvas, Worldspace Canvas or other smaller canvases.

Situation 2 : I implemented a custom Dragging method, at the end of the Drag event, OnEndDrag() is called, in which we loop through every element of the hovered stack to find if one is a "DropZone". Result: The elements in the hovered stack don't seem to match the current situation.

The PointerEventData is updated every frame as well. Setting the "blockRaycast" parameter of the dragged object to "false" also fixes the behavior, although I don't think this should affect the hovered stack, besides the dragged object itself not appearing in the list?

[mighty latch]

There also seem to be inconsistent behaviours between the different variables of PointerEventData. If I have a main object which raycast targets are children images, pointerPress returns the parent GameObject while pointerEnter returns the targeted graphic rather than its parent, not sure where the difference may come from here. My parent object has 2 scripts, one which implements OnPointerEnter and the other OnPointerDown

[small badge]

As far as I know, all of them? Input modules will generally just call EventSystem.RaycastAll(), which casts against all registered BaseRaycasters then sorts the results.

[regal olive]

DontDestroyOnLoad

[regal flare]

Actually I need it to be a bit more complex. I have a minimap as a static UI image, and an overlay on it. I procedurally create a field of view mesh which is then rendered with a separate camera with alpha = 0 background and then inverted by a shader and projected into the overlay, so as the player moves around, his field of view is projected as alpha = 0 within the overlay, which reveals the underlying map. All that is working now. However, I'd like to keep the already uncovered/explored areas in the overlay. For that I wanted to use Don't Clear flag. Trouble is - it doesn't work consistently (which I assume to be a bug), so I was looking for some ways to bypass this issue. If you look at the videos I posted in #archived-urp, you can see how the feature looks like

[mighty latch]

Oh okay thanks, sadly that doesn't answer my biggest issues but damn, Unity's system is wonky

[somber swift]

Imo even projectile bullets should be made by raycasting step by step every frame. Raycast method should be pretty cheap assuming theres no hundrets of bullets flying same time.

[mighty latch]

One method is to raycast every frame, find the distance, and if the distance is inferior to the travel speed of the bullet, act accordingly

[somber tendon]

It use the first one it hits, starting from the one with higher sort order

So, if the raycast hit a raycasttarget inside the top canvas, it will stop there, else, it will continue to check any raycasttarget in another canvas below.

[somber tendon]

The PointerEventData is updated every frame as well. Setting the "blockRaycast" parameter of the dragged object to "false" also fixes the behavior, although I don't think this should affect the hovered stack, besides the dragged object itself not appearing in the list?
that's because the dragged object always get detected as it follow the mouse position, which is where the raycast is cast. Your solution to set the parameter blockraycast (or raycastTarget?) seems like the simplest/best solution to me

[mighty latch]

I get that, but shouldn't the hover stack also contain everything that lies under the card?

[somber tendon]

Wait, hover stack?

[mighty latch]

PointerEventData.hovered

[somber tendon]

yeah I've just googled that 😅 I've never used it actually

I think that hovered stack is a result of something like raycastall while eventsystem.currentSelectedGameObject is from raycast

[mighty latch]

I'd think so as well but the results are kinda inconsistent

[somber tendon]

Or maybe it doesn't work like raycastall at all, instead it add gameobjects which getting hovered and remove those getting unhovered, that's why your dragged object doesnt appear in the list since it's already hovered...
My memory is a bit blurry, but I kind of bumped into this kind of inconsistent issue a few years a go

[mighty latch]

@somber tendon yeah, seem like the kind of thing where more documentation could be helpful, but I found a workaround for now so it should be fine

Thanks for the help

[somber tendon]

No problem 🙂
Yeah, lately documentation seems to be getting vague in some place

[somber swift]

well you can just set the max distance of raycast to match the amount you need to move according to speed. if we don't hit, then start the next ray (next frame) from the position where last ray ended.

[regal olive]

Guys I've been trying to get flying pathfinding to work but the results are not so great, unity's navmesh agent just isn't doesn't work for flying and I tried coding my own system and although it flew perfectly and followed the player it just completely sucks at avoiding obstacles so I literally have no idea where to go from here

[proven blaze]

Please help, tried everything to fix it - Releasing render texture that is set as Camera.targetTexture! Context : Android, using custom render texture (asset) in the addressable prefab. When releasing gameobject via addressable release instance - it always throws this error. What should I do?

[glacial geode]

Pure question out of curiosity, if i register a local function into an event inside a function does that bring any memory leak into play?

void Something()
{
  void DoOtherStuff()
  {
    myCoolEvent -= DoOtherStuff;
  }

  myCoolEvent += DoOtherStuff;
}```

or even simple anonymous methods through a local variable (not sure if thats the right term actually)

[sage radish]

This allocates to heap memory, but it's not a memory leak because it will always be garbage collected eventually.

[glacial geode]

when i started working with c# i read a golden rule

"please be nice to the garbage collector"

so how does that play into this?

on one hand, you are absolutely right

on the other one this puts load into the garbage collector right?

(sorry if i say something wrong, trying to make sure i get this right)

[sage radish]

Sure, delegates are objects and myCoolEvent += DoOtherStuff; is shorthand for myCoolEvent += new Action(DoOtherStuff); (assuming myCoolEvent is defined as an Action), so you're creating a new object which will eventually have to be garbage collected.

[stable spear]

Every call to Something() instantiates a new hidden object to store the local state

[sage radish]

And you can get stutters from the garbage collector if there's a lot of garbage to collect in that particular moment, but Unity's new incremental garbage collector reduces those stutters.

[glacial geode]

mhm

[sage radish]

Only if there is any state to store. In this case, there's no local variables in the method so it doesn't capture anything.

[stable spear]

yes, true.

There's potentially two allocations. Any captured variables will be stored in one class, and the event record itself is another.

You can see them both here:

[glacial geode]

Okay, im sorry where can i began to study these again, it seems like i completely skipped that part when i was learning how to work with c#, and while i have some general knowledge on stuff, i wanna know more about garbage collector and its heap, i know about its states per example (0 - 1 - 2 etc) but not any other stuff and how it micro manages

thanks for the sharplab link

[sage radish]

There are extensions for most IDEs for showing heap allocations in C# code as warnings, like:
Visual Studio: https://marketplace.visualstudio.com/items?itemName=MukulSabharwal.ClrHeapAllocationAnalyzer
Rider: https://plugins.jetbrains.com/plugin/9223-heap-allocations-viewer

[glacial geode]

thank you!

[plush elk]

can any one help me here with custom assemblies? I am having a problem

cant find do fix

everything is working good but If i bulild the game I get this

that script is a editor scrip

dont know if this is the best place to ask for help in here

ok I found out that the editor scripts dont compile

they are only for editor use, had to place the scrip in a folder in assets/editor

[undone coral]

no

the most consequential memory leaks will come from rendering effects you try to author yourself, like using render textures.

you shouldn't really worry about allocations or memory leaks or whatever in routine c# code

they might be real, but they don't matter

[glacial geode]

Hmm, I need to read into the garbage collector to bear a proper judgement

[undone coral]

that's just my #archived-code-advanced perspective

[glacial geode]

The issue while this generally isn't an issue I believe smaller end targets will be affected more probably

But I am not sure!

I'll read and I'll know

[undone coral]

what low end target?

[glacial geode]

An old spec system per example thats what I meant

[undone coral]

yeah, but name the specs

[glacial geode]

I don't have anything specific in mind, let's use as an example 4th Gen Intel cores

[undone coral]

that idea of the low spec system... it doesn't exist in reality anymore. besides, are those people going to try new games?

why would someone on a 4th gen intel try a new game?

how many new games do they have in their steam library?

we can answer this question. they're already exceedingly rare

[glacial geode]

Hm, you are right maybe its a smaller demographic than what I overthink in my head

[undone coral]

it's not just a smaller demographic, you will not meet personally a single living human being in your life with a 4th gen intel CPU who also tries new things

i understand they may play games

but they don't play new games, like yours

this is just #archived-code-advanced

[glacial geode]

(my girlfriend had a 2nd gen cpu with a 1050 ti and game and tried new games)

[undone coral]

#archived-code-general : "blah blah blah garbage collection"

yes, but what was the last new game she tried?

[glacial geode]

Horizon zero dawn I guess

Tomb raider

Etc

[undone coral]

okay... so games that are years old

besides

[glacial geode]

Don't get me wrong, I'm just a skeptic atm

[undone coral]

horizon zero dawn was released 4 years ago

like what are we even talking about

anyway

i think this is a good point well made

4 years ago!

so you have to not worry about people with low specs, pretty much ever

for a game that has 0 users, the low spec audience is irrelevant

tomb raider is 3 years old

these aren't new games

there are many good indie titles that run on low spec machines on steam that are less than a year old

it's just that, people with low spec machines also happen to be people who will not try something new in every sense of the word

usually this comes up in targeting android users, which i think is a colossal waste of time

because android users don't try new things, so why bother making your game for them

worse phones, way smaller budgets, don't try new stuff = a disaster audience

[glacial geode]

My experience with Android is my equivalent of whichever experience anyone had with lisp

So I'll take your word for it for noe

Now

[undone coral]

lol are you trying to say, horrible?

[glacial geode]

Non existent is more accurate in terms of developing

Ok I hear your points and i think you make sense for the most part

[undone coral]

what is going on here

why are you using a render texture to implement a blur?

[glacial geode]

To begin with a good demographic will have to upgrade to newer systems due to windows 11 requirements

[undone coral]

well it's more that, if you look at people on steamdb.info with +$1,000 accounts

who have indie games in their libraries

that could run on potatoes

they try a lot of new things

they have very fancy computers

they just care more

[glacial geode]

Oh steamdb.info is an excellent suggestion for comparisons right

[undone coral]

they have more money, so they buy nicer computers and spend more on games

same with the ios audience

your antagonist is poverty

[glacial geode]

Yea I'll be honest that I was ever so slightly biased due to my country (Greece) and 7/10 people I know have crappy systems

But I had to think globally

[undone coral]

don't use multiple canvases, don't make a custom drag

what is your objective?

[undone coral]

it's tough. the best platform in Greece is going to be iOS

because people have iphones, and iphones are nice

[glacial geode]

I have met 4 people with iOS in my whole life

[undone coral]

then you're in big doodoo trouble

you have to figure out for yourself

[glacial geode]

We make 800 per month on minimums wage and iOS costs like 1500 ish

[undone coral]

what you can target for people who try new things

it might be something like the nintendo switch

[glacial geode]

Nono I don't target Greece as my target, I am merely explaining what Initially had in mind

[mighty latch]

How is that advice?

[glacial geode]

But thanks for the help and answers

[undone coral]

i agree that the OnDrag stuff is really bad

but eventsystem doesn't practically work with multiple screen-space canvases

are you making a card game?

[glacial geode]

Screen space canvasses (and unity UI in general) works horribly, it has a learning curve that's basically the key of sol in music, atleast when you want complex functionality

[mighty latch]

Unless they created a better solution for custom rendering order, that's not gonna be possible

[undone coral]

what's the game though?

[glacial geode]

There is a custom rendering order

[undone coral]

^true

[glacial geode]

There was an override

I need to remember/find it

[mighty latch]

The key of sol?

[undone coral]

are you trying to make a webgl game? it's telling you what the issue is. you can't run a webgl thing on "localhost" and then have it access "prepod...lecode.games"

[crystal ridge]

Does anyone know the Steamworks API call to see if the user is on a Steam Deck?

[undone coral]

that's right, it doesn't work for flying

you can search google for 3d pathfinding unity

you can fake it by raising your object to a certain height

[glacial geode]

3d pathfinding is easily made now with the new custom unity navmesh

Fuck I'm on the road and can't fetch links

Plus if you want an accurate algorithm I suggest you look into A* as it's the most optimal algorithm for such things

Especially since Euclidian distances are easily made here with just the distance between agent and target/goal

[mighty latch]

@glacial geode afaik, there is one in Canvas

[glacial geode]

You can use a component on the children too

Any UI element will do

Buttons etc

[undone coral]

what are you trying to drag and drop?

[mighty latch]

@glacial geode I've never heard it called a key of Sol tho, I think the correct english name would be Treble clef?

[undone coral]

like a card into a spot?

[glacial geode]

Irrelevant to the topic but the English name is sol key

[mighty latch]

They're both correct, funny that they translated it directly from the french, must confuse quite a lot of people not knowing that Sol is G

[mighty latch]

I doubt that's relevant

[glacial geode]

It is cause we can give suggestions on ui structure

You can give an abstract example

[undone coral]

i'm just worried if you can't describe your game in a sentence, it just helps visualize what your issue is easily

[glacial geode]

^

[undone coral]

it would help a lot

[mighty latch]

I can, I just don't see the point

[glacial geode]

Imagine this and I'm speaking from experience

On one hand we can give you directly a quick answer and you go your merry wY

[mighty latch]

At least not to answer the question of whether there is something that canvas that allows for custom sorting orders

[glacial geode]

Way

Buut

If you can explain it and something is off we can help you design stuff even in the future with an ease of mind

It's just a way to also verify ones sanity

It helps establish the order and if something can be done in an easier manner

I can go on for days

[undone coral]

for example, to make a drag interaction, it's easiest with unirx, and the following bakes in a lot of knowledge:

class Draggable : UIBehaviour {

void Start() {

PointerEventData pointer = null;
this.OnBeginDragAsObservable()
 .Subscribe(newPointer => {
  pointer = newPointer;
 }).AddTo(this);
this.OnDragAsObservable().Subscribe().AddTo(this);
this.OnEndDragAsObservable().Subscribe().AddTo(this);

Observable.EveryUpdate()
 .Where(_ => pointer != null)
 .Subscribe(_ => {
   // check if the pointer is still pressed.
   // if not, set it to null.
   ...
   // get the hover stack or raycast here. now it will work.
   ...
   // set the transform movement
   ...
 }).AddTo(this);

...

[undone coral]

okay well, this will be the last chance to help you, but hopefully you can just briefly describe what it is you're trying to do

believe it or not the pointer event is mutated

in event system

it's ideal to use new input system instead of classic input

the approach i wrote also works for stuff like multitouch

and deals with taking things off screen, which happens frequently in the editor or windowed games

[glacial geode]

Doctor I can't check but remind me can sorting layer be applied ?

I did check briefly but can't read details on the road

Also how come you are using this in your code? Is it needed when by default a definition in c# refers to the object running?

It's not like we are messing with class constructors or getters and setters

[undone coral]

it has something to do with UniRx's extension methods

it's something idiosyncratic to it

[glacial geode]

Ah right you did mention unirx mb

[undone coral]

canvases allow you to set a sort order, you can have a "child" canvas

but... the best way to do a sort order is using the hierarchy

you already have sort order in UGUI, it's just the hierarchy

it just means the user is going about something wrong

and if only @mighty latch would tell me what he's trying to do

i would help him

[glacial geode]

Yea 9/10 it's easier to use just the hierarchy

[undone coral]

it's going to be a really common fix

like having a dummy object that is what you drag

and the visual object is constrainted to it

[glacial geode]

Yea the best way would be

To make a phantom holder

[undone coral]

yeah

[glacial geode]

That is a copy of the previous slot

[undone coral]

that's such a common pattern

[glacial geode]

With a bit tweak

[undone coral]

so i really want to know what's going on 🙂

[glacial geode]

Yea I also agree that the vague secrecy ain't helping

An abstract example is easy to do

It's not like he is disclosing company info or whatever he is working on by using examples or generalisations

That's what I've been doing for 4 years atleast @mighty latch

If it's any consolation atleast I mean

[oblique sparrow]

I'm currently making a Paper Mario style game and one big part of the battle system are the action commands, in which you need to time your inputs at the right time to do an successful action (see the normal jump here for example: https://imgur.com/a/cXOSJLw).
How would I approach implement this timing based input?
Just need to know where to start.

Also, would you go the timing by frames or by "real" time?

[undone coral]

you can sequence the combat with Unity Timeline, and add markers (https://blog.unity.com/technology/how-to-use-timeline-signals) or intervals made of two markersto denote when and which buttons should be pressed

[oblique sparrow]

That's exactly what I was looking for. Thanks!

[signal plume]

If you want to pay $100

[drifting galleon]

use unity mlapi. it's the new multiplayer framework native to unity

[urban warren]

Just fyi it has been renamed from MLAPI to "Netcode for GameObjects"

[drifting galleon]

yeah i saw that......i liked mlapi better.....although people more often consufed it with machine learning. so yeah, i get the namechange

[urban warren]

Ah, yeah I can see that happening. I personally disliked it a bit because it was more the name of the 'type' of API than a 'product' name. However I don't really like the new name either because it is to 'descriptive'.

[signal plume]

is it good?

[drifting galleon]

definitely

[signal plume]

Is player server side, or can i place all the lobbys in my own server?

[drifting galleon]

it should support user servers and dedicated servers

[signal plume]

Nice! Thanks for the info

[hushed fable]

Might make a bit more sense when you consider that the DOTS networking solution is called netcode

[urban warren]

Not any more it's not. It is now "Netcode for DOTS"

[hushed fable]

I imagine the goal was to reduce confusion within Unity products

[urban warren]

I mean, I get it and it makes sense, I just don't like how it sounds 😛

[hushed fable]

Yea the branding isn't very catchy 😄

[urban warren]

Question, is it true that doing even P2P multiplayer is 1.5x as much work as single player?

[drifting galleon]

maybe even more. in a performance aspect

if that's what you mean

[urban warren]

I mean, as for as dev time goes.

Multiplayer vs singleplayer.

[hushed fable]

There's #🎥┃cinemachine if it's something very specific to CM

[compact ingot]

1.5 is a very optimistic number

[urban warren]

Not surprising, I think 1.5 is the number I saw a number of years ago when I looked in to what multiplayer entailed. Thanks.

[hushed fable]

There are a lot of variables to that, like how what frameworks you are/aren't using and what kind of quality you are aiming for.

[drifting galleon]

since we're on the topic of multiplayer right now: what's up with SpatialOS? i've still got a legacy account but appearantly it got moved to be a part of zeuz? i can't find any SDK though

[fickle crane]

I'd estimate.. 3x.

[mighty latch]

Let's say I want to detect entities within a certain range of my gameObject every frame, what would be the most efficient way between a trigger collider and Physics.OverlapSphere?

[zinc flicker]

Hi! I need to make my own Input library in order to have a frame independent Input

Do you have any kind of tutorial to get started with something like that?

Dunno where to start tbh

[hushed fable]

New input system should be decent

[stable spear]

no you don't. just ensure your code performs well enough that it can work with a high frame rate. (Unity can go well up to 250fps)

[zinc flicker]

I don't need something decent

I wanna learn to make my library so it is great

It's a rhythm game so I have to be as accurate as I can

[hushed fable]

Did you check lower level input system stuff?

Yea I know, it's supposed to be good now

[zinc flicker]

Yep, nothing worth tbh

Plus its frame independent

[hushed fable]

I know people who used native input plugins in the past but have no issues with the new input system

[zinc flicker]

Many people who worked on games of the same type told me they use native input plugins

So, how can I make that?🤔

[zinc flicker]

yes I do, it's a rhythm game I need accuracy and calling it once a frame isnt enough

sadly

[stable spear]

this is an imagined problem unless you actually have demonstrated it

at a frame rate of 250fps, the delay between frames is 4ms. The perceptual accuracy of humans (when it comes to musical beats) is much larger than that

[plucky laurel]

it may be possible that they dont really operate on perception

have you seen the people that play guitar hero/ddr and the like?

their neural networks have the songs and keypresses integrated on spine level

[zinc flicker]

who plays at 250ms on console? lmao

its not an imagined problem, pressing once a frame is not enough for a player with quick reactions in rhythm games

[stable spear]

your making a console game?

[zinc flicker]

im thinking about the user experience

[stable spear]

it's imagined unless you already have a product to show

premature optimization

[zinc flicker]

PC, console and mobile

[stable spear]

you could build your program, and if it really is too laggy with frame-input, THEN build your own input module

[zinc flicker]

its not imagined since every man I know who worked on a rhythm game has faced that same issue

[hushed fable]

Worth considering what building a native input module means in practice when you are shipping to 6+ platforms

[zinc flicker]

otherwise I wouldn't be asking 😭

[stable spear]

one of the ways people procrastinate on a project is by worrying about problems at step 50 or 60 while they still haven't completed step 2

[zinc flicker]

yeah...

[hushed fable]

They did face it until new input system came out 😛

[zinc flicker]

new input system doesn't works for that

[hushed fable]

It looks like you can increase the polling frequency of the input system independently of the framerate

[stable spear]

new input system was designed to be faster and more efficient than the old one.

[untold moth]

Looking a bit into the new input system docs, and it seems to be receiving events directly from the native input, so it should be frame independent.

[hushed fable]

https://github.com/Unity-Technologies/InputSystem/blob/develop/Packages/com.unity.inputsystem/InputSystem/IInputRuntime.cs#L135

I would suggest actually looking into the existing lower level parts of the input system

[stable spear]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/api/UnityEngine.InputSystem.InputSystem.html#UnityEngine_InputSystem_InputSystem_pollingFrequency

[zinc flicker]

not enough since it has a lot of input lag and you can only know when the button has been pressed

[hushed fable]

It can save a lot of time compared to learning the system APIs for input for 6 different platforms

[zinc flicker]

but not how long since you pressed it

[stable spear]

I think flynn is just fishing for an excuse to not build his game

[hushed fable]

Didn't someone mention that there are timestamps?

[zinc flicker]

what?

man I'm just asking a question

[untold moth]

I think you can know the exact time of the event

[stable spear]

you're asking a question but you're ignoring all the good answers, and you just keep insisting on your imagined premise

you haven't actually tried to make the new input system work for your game. You probably haven't even built your game yet. You're just assuming it won't work

[zinc flicker]

man what I'm saying is that I already tried all of that, I'm thankful for the help

but I would want to know how to make my own library at least for PC now

plus, you assume I didn't started with my game out of nowhere, I just asking something nicely 😭

there's no need to be rude

[untold moth]

I think you're kinda misunderstanding due to a lack of experience. Even if you're gonna write your own thing it's gonna be something very similar to what the new input system does.

And most likely, a team of professionals can do it better than you.

[plucky laurel]

dont take personally

[zinc flicker]

Maybe, but most of people who worked on big rhythm projects for Unity said to me it was normal to have those issues since the Unity Input System (old and new) are not efficient for that kind of games

[zinc flicker]

Obviously

But learning to make my own library is also a way to learn and practising I'll eventually know what's better for my game

It gives me a lot of experience and in every jon they'll appreciate it

However, if people can teach me something about the New Input System I won't be rude either since I can listen to people

[hushed fable]

Well I would like to hear your results of the suggestions

[untold moth]

Well, I don't have much experience with the new input system, but a quick look at the docs makes me think that there's no "better"/"less lag" way to get input. try looking at it yourself.🤷‍♂️
They even have a diagram demonstrating the architecture
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.2/manual/Architecture.html

[hushed fable]

Did changing the polling rate do nothing?

[zinc flicker]

Not so much

But that's because the game is very demanding regarding inputs

[zinc flicker]

I'll take a look into it!

[hushed fable]

Make sure to try to hook into low level events and not the action system

[untold moth]

In either case I don't think that you would be able to get a "direct" callback when a certain input is triggered, because of how OS handles input(if I get it right). The right way would probably be to know the exact time of the event and design your code around that.

And the new input system seems to provide that data.

[zinc flicker]

I'll tell you, since I think it may be an interesting subject after all

I will re-try everything and even try new things

Your suggestions may be able to help me out (I hope so)

Thank you anyway, you're so nice guys

[plucky laurel]

doesnt rewired have its own input polling?

[untold moth]

As for your own plugins, you'll probably need to write some c++. And not the most basic one too.

[zinc flicker]

Huh anyway, do you have any tutorial to get started with libraries? I'm just curious at this point

[zinc flicker]

😭😭😭

[zinc flicker]

It's frame dependant AFAIK

[untold moth]

probably start from reading this:
https://docs.unity3d.com/Manual/NativePlugins.html
https://docs.unity3d.com/Manual/NativePluginInterface.html

Then this:
https://docs.microsoft.com/en-us/previous-versions/windows/desktop/ee418748(v=vs.85)

Then you'd need to hook your c# code to an event from the c++ side..?🤔
That's as much as I cant tell without actually researching into the topic.

[zinc flicker]

Thank you, that's already helpful

I might take a look into that someday

[untold moth]

I imagine that for that to work with android, you'd need to write a similar plugin in Java(?)

And other native languages of different platforms

[hushed fable]

Hey you jumped over Mac and Linux 😛

[untold moth]

lol

isn't Linux c++ though?🤔 I always thought it's c++

[hushed fable]

Yea I imagine both would be C++

[untold moth]

The api would be different of course

I'm not even sure about Mac/ IOS... I remember IOS was based on a language with a funny name, but don't remember exactly...

Oh, Objective-C is C based🤔

Always thought IOS programming is from another planet, but I guess it's not that different.

[sinful coyote]

I have a crash I'm in the middle of trying to track down, but which I suspect may be related to IL2CPP + burst/Unity.Collections in some way.
In my player.log right at the top I get 2 of the following warnings:

The method `Int32 Try(IntPtr, Block ByRef)` must have `MonoPInvokeCallback` attribute to be compatible with IL2CPP!
UnityEngine.Logger:Log(LogType, Object)
UnityEngine.Debug:Log(Object)
Unity.Burst.BurstCompiler:CompileUnsafeStaticMethod(RuntimeMethodHandle)
Unity.Collections.Try_00000C2D$BurstDirectCall:GetFunctionPointer()
Unity.Collections.Try_00000C2D$BurstDirectCall:Constructor()

(and the same for 00000C23)

Under certain conditions (I'm still trying to nail down), I get a crash to desktop in a build - I will make a mono build and see if it happens there and also test in the editor to see if I can replicate it, but in the meantime I wanted to check if it's perhaps a version issue that someone here knows about specifically: I'm using:
2020.3.19f1
Collections 0.15.0-preview.21
Burst 1.5.6 (also got the same on 1.5.4)

(here's the player.log minus some unrelated debug.logs in the middle: https://gdl.space/vufusumica.js)

Hello, I have an issue with optimisation, I have sprite skin component that's very slow and I don't know why. I'm using the 2D animation package for skeletal animation which I guess I'm not using right

[zinc flicker]

Is the New Input System really frame independant or is it in FixedUpdate?

[hushed fable]

The backend polls some devices at the set polling frequency and some devices have events fed realtime from the OS afaik.

Not exactly sure what options you have for consuming that data

[stark quartz]

Is there any specific channel for questions about Unity's Particle System, a great particle system

[sly grove]

#✨┃vfx-and-particles

[zinc flicker]

Which devices use realtime?

Like, is there any set list or smth like that?

[stable spear]

what is realtime supposed to mean in this context? Everything is polled if you look deeply enough

USB is based on polling devices

[hushed fable]

Realtime in the context of the input system backend. It doesn't necessarily mean that the input comes in any faster depending on the rest of the input chain.

And all of these details can and probably will change based on the platform and device type

[compact ingot]

realtime means "input will arrive no later than X after it was performed" i.e. after the original switch in the device that turned a 0 into a 1 was triggered", this guarantee DOES NOT mean that X will be a low number.

[zinc flicker]

I understand

thanks

[compact ingot]

you can also manually update the input system if you like, maybe from a custom thread or custom player loop

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/api/UnityEngine.InputSystem.InputSettings.UpdateMode.html#UnityEngine_InputSystem_InputSettings_UpdateMode_ProcessEventsManually

options are Update/FixedUpdate/Manual

[zinc flicker]

but if I put a high polling frequency it would be frame independent, right?

not sure how I need to update it tho

[compact ingot]

it can run faster than update but not faster than your CPU can handle

[zinc flicker]

if I put Update it means it reads Input at polling frequency but it reads it after a frame or what does it mean?

[zinc flicker]

enough

if it is optimized I don't think it would be such a big deal

[compact ingot]

it reads all input events and aggregates them (somehow), but updates you ingame events only once per update

[zinc flicker]

ok, it reads it when you press it and it updates in the game after a frame

amirite?

not sure if I understand correctly

[compact ingot]

when you update manually, those aggregations happen each time you trigger that update, and you have to deal with the async between that and the default player loop yourself

[zinc flicker]

there's not really a player loop, it depends of what you mean by PlayerLoop

[compact ingot]

its like the problem when you query input events in FixedUpdate but get none because they are out of sync

[compact ingot]

there is always a player loop

its what calls Update() and LateUpdate() and BeforeRender() etc.

[zinc flicker]

oh okay

it'd better going by the Update option then ig

[glass wagon]

When you have structural and process problems, can't figure out a way forward to achieve goals, how do your break it down: pen and paper, drawing app, word, diagrams? Just start and try to get through chunk by chunk?

[tough tulip]

Just start and try to get through chunk by chunk
thats the worst approach ever and mostly you'll waste your time when you face a new problem which you never thought of, and then end up repeating the same.
other than that, anything else works. pen-paper/drawing/diagrams/flow chart/etc etc. for me, i used to write down the logic sequentially. and then write down all edge cases and their possible solutions.. with time you'll eventually do it all mentally

[glass wagon]

I've been doing it mentally for a few years, but recently hit a snag, and need to figure a way to map out the problems and flows and edge cases and thoroughly design the structure, as I'm not capable of holding or perhaps even building the entire model in my mind.

[stable spear]

thats the worst approach ever and mostly you'll waste your time
story of my life 😦

[golden oriole]

I try to break the problem down into more and more granular steps. My very first method may look like

{
return new Sandwich()
}

And then I break down those steps into steps:

{
Sandwich result = new Sandwich();
result.TopBread = AddBread(customer);
result.Filling = GetFilling(customer);
result.BottomBread = AddBread(customer):
return result
}```
And eventually  you're describing the most granular steps of what you're trying to do.

[glass wagon]

Thank you! Needed this to jolt my brain back to being sensible. Very grateful!

Fish, veggies, steaks, salads, etc. And have always kind of choked on the one-bit-at-a-time because there's so much that's gotta be done somewhat concurrently, and interdependently, with limited hotplates, ovens etc.

But the sandwhich metaphor, therefore, and two stage breakdown, a big reset help. CHEERS!

[pulsar owl]

when instantiating a gameobject containing some TMP assets the TMP doesn't render until I go into the inspector and manually change the text from "Test" to "test1" for example. Would anyone know why? It's a really weird bug. Really struggling on this and no amount of internet searches brought up a solution.

[split sundial]

Guys, I'm making a card game and I'd like to implement networking, but I'm unsure as to which library to use for that.. Any suggestions?

I'd mostly use it for player authentication, storing some data (such as player decks) and making 1v1 matches, so I don't need anything too powerful, but ease of use is important to me

[golden oriole]

IIRC UnityEngine has a native networking library, probably your best bet.

[split sundial]

Yeah, I think it's called netcode, but I've also read some good stuff about a lib called Mirror, so I thought maybe someone here had some tips on which to use

Mirror does seem more focused on MMOs though

Oh, I just realized there's a networking channel, I'll go ask there

[golden oriole]

Since Unity is having trouble encoding objects as both json and as AssetDatabase Objects, I'm trying to create a template class to be able to save things in the AssetDatabase so I don't need to extend every single one with : ScriptableObject

Here's my template class:

    public class ScriptablePersistedObject : ScriptableObject
    {
        [SerializeField]
        private object payload;

        public T GetPayload<T>()
        {
            return (T)payload;
        }

        public void SetPayload(object payload)
        {
            this.payload = payload;
        }
    }```
When I save this, the object does end up appearing in my assets, but the inspector as well as the `.asset` file show no actual data in the payload. Does anyone know of a way to get `[Serializable]` to work with template classes, or is this a little beyond the capacity of Unity's serializer?

[proud atlas]

Does anyone know if you can write into Downloads folder on iOS?

[austere jewel]

What type of data are you trying to serialize? And why would you want to do that with many individual scriptable objects?

[golden oriole]

It's persistent data related to my project, there's both user-generated data and prebaked (primitives, or containers of primitives), and I'd like to be able to store in both json and unity-serialized format without thinking about it.

[austere jewel]

Well, if you use a better json serializer like NewtonSoft's you should have no trouble serializing serializable things.
As for the asset database, [SerailzeReference] is a thing, but what you're doing kinda smells like it could be done a better way. I've never had to serialise anything like this before

[golden oriole]

what you're doing kinda smells like it could be done a better way
I'm sure... the intent is to be able to have a human-readable version of the user saved data so they can view it on demand, as well as have it generate in-engine.
I'd also like some premade versions, and those I'd like to be saved in the engine, and since they're there, I might as well be able to edit them through the inspector.

[tough tulip]

thats because if your object isnt serializable then unity wont be able to save it

[austere jewel]

If you mark the field with SerializeReference, and the data you put in it follows the serialization rules it should work

[golden oriole]

It can only save objects as assets that extend scriptableobject.

[tough tulip]

Not any object. Only the ones which are serializable

[vivid prairie]

Hi. Im trying to implement a floating origin and I have a problem with light probes. I dont know how to move them via script. I've only come up with overriding anchor on meshrenderer but if I have to override a transform for a couple hundreds GO it will be very slow. Any ideas? :3

[stable spear]

The fast way to move a whole bunch of gameobjects at once is to have them all under a single root object, and move that.

[solemn bison]

Does anyone know how SceneManager.activeSceneChanged work? Cuz I don't, not even after reading the documentation

[vivid prairie]

Yeah I know that trick, but unfortunately light probe group still stay there where it was :/

And I need to compensate it for baked light, or move light probe group somehow

[young spoke]

anyone know why The Lerp's would have inconsistent speed in this code?

[stable spear]

oh, game objects marked static won't move correctly

and baked lighting will probably malfunction, hm

[vivid prairie]

yeah thats a big problem, haha

[solemn bison]

did u try multiplying the spee dby Time.deltaTime (or any of the variations)

[young spoke]

it is here

[solemn bison]

:|

[stable spear]

Just to check, what's the reason for moving the origin?

[vivid prairie]

I have artifacts over 1000 m from the origin, and Im making a game on VR so it's even more noticeable :/

[stable spear]

Hm. The usual way of dealing with that is to break your game into separate Scenes, and load a new scene in when your player gets far away enough from the origin

If you've ever played Half-life: Alyx, it does that quite noticeably, with checkpoints that take several seconds to load up

[vivid prairie]

Yeah That will work if I won't try to make open world, hahah

[stable spear]

ah

[vivid prairie]

I've even found a function to overcome static batching "StaticBatchingUtility", honestly didn't test if it's working but as i read the description it should :3

[stable spear]

I don't see how that is relevant

[vivid prairie]

I think i can write custom shader that compensate the origin shift

[golden oriole]

@vivid prairie You could try loading your world in chunks, and have each chunk load and unload as it gets closer to the player. The way I would get that to work well without crazy floating point issues would be to make your player always at 0,0 and essentially invert movement, either that or use some clever partitions to snap your player back to the other "edge" of the chunk when they reach the edge and re-center.

[stable spear]

you'd have to replace all shaders you use. And it depends on what artifacts you're seeing. The physics calculations will also suffer.

[vivid prairie]

It looks like the each vertex move <1mm every direction

[stable spear]

are you generating the world on the fly, or is the entire level in your scene already?

[vivid prairie]

The entire level is on the scene

[stable spear]

how far out does it go?

[vivid prairie]

I would like to have at least 4x4 km world

[golden oriole]

Are you using any LoD meshes?

[vivid prairie]

I'm trying to implement hlod

[stable spear]

is this thing going to be multiplayer?

[vivid prairie]

no

[tough tulip]

is interpolateTime correctly going from 0 to 1?

[stable spear]

well, I don't know what to suggest. By the time you get to 4096m, the resolution of float is down to 2048 slices per meter. Which I imagine is going to feel terrible in VR. What you really need is double-precision coordinates for this kind of thing.

[austere jewel]

I imagine this is the issue. If you got within a distance of the next lerp that was beneath your check, and then it looped because of a longish frametime it would reset

[stable spear]

If you do shift origin, you may need to give up baked lighting, reflections, and such. But maybe keep asking.

[young spoke]

have any examples for a good replacement?

[austere jewel]

You should just loop with an if statement and handle the logic of switching targets in it. Instead of trying to generalise it into one line.

[young spoke]

got it

[golden oriole]

One solution the Kerbal Space Program uses is to centralise the camera at the origin, and rotate the world around it. The limited float space of our “world” is used purely for rendering, and the actual coordinates of objects in the world are stored elsewhere in a better - custom - system, and translated into world space on every frame.

KSP also uses the scaled skybox solution to represent distant celestial bodies. As the player gets closer to these objects they're hidden in the skybox and a realistically sized version is added in the player space which they can interact with.

[vivid prairie]

Yes, but I want to keep my baked lighting and thats a problem

[golden oriole]

What's the benefit of keeping your baked lighting?

[vivid prairie]

better visuals

[stable spear]

Note that Unity's representation of the level uses the same 32-bit floats, so you've already lost precision in the description of the level far away from the origin

[golden oriole]

Okay... and do you really need the precision of baked lighting at >1mi away?

[stable spear]

Shifting it back to the origin won't fix any errors caused by that. Including errors in the light baking.

er wait, that might not be true if Unity uses relative coordinates for the bake

nevermind

[vivid prairie]

The problem is that the mesh is vibrating, I think the <1mm error for light baking will be fine

[golden oriole]

I think I'd break the world into chunks, pre-bake lighting on those chunks, and then swap out non-baked chunks and baked chunks as the chunks enter the player's perimeter. As for making sure things still look pretty all the time, lots and lots of LOD tuning and level design will help

[vivid prairie]

I think we get off topic 😄 the main problem was to move baked light probes

[golden oriole]

But you can't move light probes in baked lighting...that's kinda the point. 😐

[vivid prairie]

yes

so nevermind

[young spoke]

im back to sqaure 1, nothing seemed to help

I might juust have to rewrite the code but I really dont want to do that

my first time working with lerps and its super frusterating

[severe grove]

Hey guys. I am attempting to transition some AStar code over to unity jobs. Everything is going swimmingly except this part. Tilemap is clearly something I cannot store inside a job so how do I get the hasTile check to work inside? is there a way to have it call an external function?

[stable spear]

Can you store the HasTile info ahead of time (in a 2d bool[,] array), and pass that to the job?

[mint kraken]

@severe grove transfer the tile from 2d/3d array to 1d array and use it

that is the only way to have 2d array in job&burst

[severe grove]

So I need 2 jobs then. 1 to construct the node array. Then I check the nodes. then send it back to a new job to finish?

[mint kraken]

no you have to store the data as 1d nativearray and use it directly

your first job won't able to read 2d array as well

[severe grove]

navigationmap.HasTile is just using the unity Tilemap

nodeArray is already a 1d array

[mint kraken]

if u have to use job/burst you have to store the .hastile in your node when everything changed

[severe grove]

That is what CalculateIndex does.

[mint kraken]

and tilemap is a class i guess

[severe grove]

correct

https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.HasTile.html

[mint kraken]

use a class in job/burst is not possible

Brackeys have nice video about it

[dire sparrow]

Late reply but what I want isn’t an installer

Just a single .exe file

[queen plover]

I believe you can with an external solution

but I don't know any software that will do it for you

[compact ingot]

that is not possible

[queen plover]

I might just be thinking of an installer though

[dire sparrow]

I mean I plan to release the game via Steam or Microsoft Store

So no need for an installer

I maybe thought it would be self contained

Like in OSX

[compact ingot]

apps in OSX/macOS aren't self contained. .app is just a special package format that macOS treats in a particular way... kinda like an archive with a pointer to a specific file that gets executed when you double click... like an alias in the StartMenu.

[queen plover]

If you plan to release it there, there should be no problem with just leaving it as is

[compact ingot]

it just looks like that

[shadow seal]

If you look in any "Made with Unity" Steam game's install folder you'll see all the usual suspects

Hello, i'm having trouble with understanding closest point to plane,

        public static void DebugMouseCastToWall(float dist=5f) {
            Handles.color = Color.green;

            var ray = HandleUtility.GUIPointToWorldRay(Event.current.mousePosition);
            var tr = SceneView.currentDrawingSceneView.camera.transform;
            var wallpos = tr.position + tr.forward * dist;

            var plane = new Plane(-tr.forward,wallpos);
            var closest = plane.ClosestPointOnPlane(ray.origin);

            Handles.RectangleHandleCap(0, wallpos, Quaternion.LookRotation(-tr.forward,tr.up), 1f, EventType.Repaint);
            Handles.DrawDottedLine(ray.origin,closest,1f);

            Handles.color = Color.red;
            Handles.SphereHandleCap(0, closest, Quaternion.identity, 0.1f, EventType.Repaint);

            Handles.color = Color.white;
        }

expected behavior of this debug : a line will drawn from mouse position to the closest point on the plane which is 5m away from scene view camera.

output when i test it : the mouse position is correct, but the closest point always in the middle of the screen.

yellow is the mouse pos, red is the closest point

[compact ingot]

that mouse-ray starts at (camera position / screen center) with direction to that mouse pos., closest point to a plane perpendicular to the view-fwd-vector when viewed from a camera with that view-fwd is the view center.

a plane also has infinite size, so...

what you maybe want is ```cs
var isHit = plane.Raycast(ray, out float atDistance);
closest = ray.GetPoint(atDistance);

[sullen halo]

thanks Anikki, i changed the code to this

        public static Vector3 MouseCastToWall(float dist = 5f) {

            var ray = HandleUtility.GUIPointToWorldRay(Event.current.mousePosition);
            var tr = SceneView.currentDrawingSceneView.camera.transform;
            var wallpos = tr.position + tr.forward * dist;
            wall.SetNormalAndPosition(-tr.forward, wallpos);

            float hit;
            wall.Raycast(ray, out hit);
            var closest = ray.GetPoint(hit);

            return closest;
        }

and it works! i still don't understand much, must review again

in theory a raycast like this and Plane.ClosestPointOnPlane must yield same result 🤔 . but my 2 code block say otherwise...

[simple thunder]

hello i was wondering how i could make it so when i look at a cube or anything with a certant tag i can press f and it launches me in the direction im looking in. (wich is the cube>??

[frozen imp]

@simple thunder Don't cross post, and there's nothing advanced about it.

https://stackoverflow.com/questions/69934430/making-a-moddingapi-for-my-unity-game-and-call-functions-without-direct-referenc If someone has a solution for my question, I would really appreciate it.

[worthy lodge]

I use await to call functions with a delay using generics, but I noticed the thread/async task still runs when I stop play mode, which causes a MissingReferenceException

public async void Delay<T>(Action<T> delayedMethod, int delay, T value)
        {
            await Task.Delay(delay);
            delayedMethod(value);
        }```

Is there a way to stop all tasks when stopping the game/exiting playmode?

[strange osprey]

How can I cheaply set default values to an array of a struct
So i want my Struct.Int property to be -1
instead of 0
when i create a new list
but without it being expensive
cuz the array is large

[fresh salmon]

Initialize the Struct.Int property as -1 in the struct declaration directly.

public int Int { get; set; } = -1;

[modest lintel]

You say array and then you say Struct.Int 🤔

[fresh salmon]

They have a struct array (or list, both terms are employed here, but I'll go with array since fixed size of default values etc.).

Initializing it fills it with default(T), so all default values of the struct. They want a member of this struct to not be the default (0) for default(T).
That's how I understood it

[modest lintel]

ooh my bad. When I first read it, I read it as they had an array inside a struct

[strange osprey]

so basically i create a new empty struct array

and i want all the values of the struct.int to be -1

without looping through the full array

Assets\Scripts\TerrainGenerator.cs(33,24): error CS0573: 'TerrainGenerator.Vertex': cannot have instance property or field initializers in structs

i still get this error

        struct Vertex 
        {
            public Vector3 Position;
            public int Index { get; set; } = -1;

            public Vertex(Vector3 position, int index) 
            {
                Position = position;
                Index = index;
            }
        }

[fresh salmon]

Ah yes, struct limitations

[modest lintel]

just put it in the constructor

[fresh salmon]

Can't initialize it in a default constructor, as you can't provide your own implementation of it (errors as well)

[strange osprey]

there are no errors in visual studio code

tho

how come

[fresh salmon]

I might have been mistaken 🤔 it compiles for me as well

And most importantly, works as expected

Ahh it's because you have to init all members before control leaves the ctor

Shouldn't be a problem for you

[zenith ginkgo]

Hello! How would i fix this? Im unsure what its asking me.

Script: https://mystb.in/SpeakerBiolAirlines.csharp

When i press Play in the editor, it works fine for the first time the scene is loaded. if i get to the end of the level and reload the scene, This comes up ^^

[strange osprey]

wdym

[fresh salmon]

Talking to myself lmao

When you create an empty struct constructor, you have to initialize all its members inside of it

Otherwise it yells at you

struct S {
  int x;
  int y;

  public S() { // error, 'y' is not assigned a value.
    x = 42;
  }
}

[sly grove]

Actually pretty sure it's illegal to have a zero-property struct constructor at all.

[fresh salmon]

Yep, the errors just stack up

"The field or propety 'whatever' must be fully assigned" or something like that

[sly grove]

Looks like that might finally be changing in C# 10 though https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/struct#parameterless-constructors-and-field-initializers

[fresh salmon]

Oh you were talking about the parameterless ones

Yeah, they changed it

That may also be why it was compiling on my machine, .NET 6 installed

[strange osprey]

@fresh salmon any ideas on solving my issue

[fresh salmon]

Just scroll up, I made a snippet

[fresh salmon]

Like, right there

Well, it doesn't work in Framework, so it will not compile for you

The good old foreach loop it is then

error CS0568: Structs cannot contain explicit parameterless constructors

[strange osprey]

so it doesnt work in unity?

[fresh salmon]

It will not

[strange osprey]

i read something were default structs are allowed on c# 6

what version does unity use

[fresh salmon]

C# 7 or 8

But

What we're talking about is parameterless constructors, which were implemented in C# 10, which itself was released less than one week ago

Unity definitely doesn't support that

[strange osprey]

but default structs should be supported then

since its c# 6

do i have to change a setting or something

[fresh salmon]

Read my messages again

[strange osprey]

structs i mean

[sly grove]

Field initializers in structs are not supported. That's what your error was about

[strange osprey]

yes but it works in vs code

just not in unity

that i dont understand

[fresh salmon]

Assuming MyStruct is a struct

public MyStruct() {} // Not allowed, until C# 10

[sly grove]

Your VScode isn't configured properly

public int Index { get; set; } = -1;

That = -1 part

Is the problem

That's a field initializer

[fresh salmon]

Nah I also have suggestions for refactorings in VS, even if they're not supported yet. No error in VS, errors in Unity

[sly grove]

Not supported until C# 10

[strange osprey]

oh ok

[fresh salmon]

VS prompts me because I have NET 6 installed, but it shouldn't be. Something going on with VS's Unity integration

It simply does not check for the current project version and/or doesn't disable analyzers for other installed versions

[strange osprey]

alr i just used a for loop

thanks for the help 👍

[zenith ginkgo]

Anyone know?

[wispy maple]

Anyone has any idea why every time i press play i get a null reference exception pointing to my unsubscribe line? The game plays normally and everything seems to be working fine btw including the event logic. Hair pulling stuff

[compact ingot]

does that class execute in edit mode? In any case, it is trying to find an instance of that FoxlairEventManager that has been destroyed already... which happens before you enter playmode as a part of the edit mode cleaning up.

[wispy maple]

OMFG thanks dude. I had a leftover [ExecuteInEditMode] above the class🤦‍♂️ FML

[misty glade]

because your singleton instance is likely being destroyed before this object.. Is your action in FoxlairEventManager static? If so, you can just omit Instance from that line

(and in your Start() method)

Oh, oops, Anikki already answered, too. I was going to say something about unity doing weird things if your manager is executing in edit mode but he beat me to the punch

*shakes fist at @compact ingot * you're too good, my friend

[zenith ginkgo]

Me me, mines not been answered

[compact ingot]

nah, i've just been there

where is it?

[zenith ginkgo]

Is that a reply to me?

[misty glade]

👆

Need a little more information, I think? like the code where the errors are happening nevermind i see you posted it, reading

[compact ingot]

you need to set the frame buffer to the render texture, then grab the render texture pixels, and then set the frame buffer back

[zenith ginkgo]

I have no idea what that means

[compact ingot]

sec

[lapis shale]

so I am adding animation to my game and I had 2 variables for moving horizontal and vertical but not since I have the animator variable I dont know what to do. In the move_input function I put player_animator for the vertical and horizontal but for move_direction the vertical_move and horizontal_move is still there because those are floats and i will get an error when I try to use player_animator.

using UnityEngine;

public class Movement : MonoBehaviour
{
    Rigidbody rb;
    public float speed = 5f;

    float drag = 6.9f;

    public float move_multiply = 10f;

    public Animator player_animator;

    //if i made it public then i would have to set avalue like a dumb ass
    float horizontal_move;
    float vertical_move;

    Vector3 move_direction;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();

        rb.freezeRotation = true;

        player_animator = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        move_input();
        PlayerDrag();

        // "Vector3 move_input = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));"
        // "rb.MovePosition(transform.position + move_input * Time.deltaTime * speed);" this is a basic rigidbody movement code
    }

    void PlayerDrag() //makes the player not slide like ice
    {

        rb.drag = drag;

    }

    void move_input()
    {
        player_animator.SetFloat("horizontal", Input.GetAxisRaw("Horizontal"));
        player_animator.SetFloat("vertical", Input.GetAxisRaw("Vertical"));

        

        move_direction = transform.forward * vertical_move + transform.right * horizontal_move; //when we the player looks to left or right the movement will continue to go the way the player is looking
    }

    private void FixedUpdate() // so our movement is smooth af
    {
        movement(); //calling the move thing
    }

    void movement()
    {
        rb.AddForce(move_direction.normalized * speed * move_multiply, ForceMode.Acceleration); //the epic movement comes into play
        //normalized makes sure the magnitude is just 1
    }
}```

[sly grove]

I read what you said but honestly have no idea what you're asking for help with.
I will say it seems like you're never writing anything to horizontal_move or vertical_move, so they will obviously not do anything for you.

[compact ingot]

i think that yield return null; might be a problem, also, you might need to do an explicit RenderTexture.active = null after releasing the render texture.

[lapis shale]

I need help with player movement and it will not work since the variable player_animator is not a float

so I do not know how I will replace the vertical_move and horizontal_move

[zenith ginkgo]

Should i just make it a normal void @compact ingot ?

[sly grove]

Shouldn't you be reading those values from input? What does the animator have to do with it?

[compact ingot]

just don't skip ahead one frame right when you want to take a screenshot

that GL.Clear is probably not needed or should execute immediately in any case

[lapis shale]

i am adding animation the my player movement so when I move it will show it walking

[zenith ginkgo]

just don't skip ahead one frame right when you want to take a screenshot

What would i use instead? wait end of frame? or just dont have a coroutine

[compact ingot]

don't clear the frame buffer, just use what's already in there (should be clear anyway); or if you want to explicitly render a camera you'd just use Camera.Render()

[sly grove]

the animator is irrelevant to the movement code. Ignore it

Get your input values from Input.GetAxis etc.. as normal

[lapis shale]

if id ont add it then when I walk it wont show it walking

[sly grove]

You already have that part working
