[unkempt swallow]

ive never seen something like this in my life

also the solution im gonna use is that github repo and this code

no idea if its what i wanted, but the values look good enough i guess

[polar marten]

if you want to visualize this stuff, ask chatgpt to do it for you.

it will use code analysis

pay for plus

i mean the $20/mo

[vestal arch]

why not use stuff that's specialized specifically for that kind of stuff

[chilly surge]

It doesn't matter what the mean is or whatever, from that curve they draw, for example f(7) is about 5x as f(350), so what they want is for a 7 kg fish to be 5x as likely to appear than a 350 kg fish. They want to be able to randomize according to this curve, and they want to be able to adjust this curve.
I've already explained the general algorithm to achieve the "randomize according to any curve" part. If doing the integral is a bit too hard math wise, then well you just have to pick curves that you can do, or use a library that handles all the integrating for you.

[vestal arch]

instead of, yknow, a hallucinogenic LLM

[polar marten]

🥺

[unkempt swallow]

its just that iam to stupid to understand what you wrote, i copied it into notepad to study it later but its definetly waaaay above my knowledge

[polar marten]

it's just that it's wrong

don't worry about it

[chilly surge]

How is it wrong?

[vestal arch]

you wanna explain why?

[chilly surge]

I can do an example calculation right now to demonstrate how it works.

[unkempt swallow]

i mean what Burrito wrote is exactly what i want (function wise)

any example would be great, im down to test it out, the solution i have now is not ideal since it still has many high numbers

[polar marten]

a way to think about this is, that if you want the "Average" fish to be about 20kg, choose a scale of 1/5, because that is 20% of the way between 20kg and your "max" of 100kg
so you want weights between 1 and 100. you will discard and reroll above 100kg.
so something like randomexponential(scale=1/5) * 100 + 1. if it's greater than 100, reroll.
here is the plot, which is basically what you want

does that make sense @unkempt swallow ?

[latent latch]

If you did computer algs or probability you'd run into it

[chilly surge]

They want adjustable curve, not just one specific curve.

[polar marten]

🥺

focus on what i am saying

i know a lot about this

[unkempt swallow]

idk what you described with words, but the picture is correct, thats what i want

[polar marten]

i know

[unkempt swallow]

yes, so i can use it for something else, lets say i want the reverse, i want many high numbers and low numbers should be rare

[polar marten]

the important thing is that when you want something like "really rare fish weights", but for gameplay purposes you want to discard fish above 100kg, i mean, go for it

[unkempt swallow]

im so confused rn

[polar marten]

i already wrote what you need to do

[unkempt swallow]

how do i achieve this with the randomexpo function that wants min and lambda, i thought i understood but im getting weird results

[polar marten]

randomexponential(scale=1/5) * 100 + 1. if it's greater than 100, reroll.

[chilly surge]

Exactly, and the method I've outlined will allow you to do any curve, curves that falls off, rise up, dips in the middle, whatever you want.
But anyways, if you want an example math to go through I can write it out, otherwise I'm just going to exit the conversation because it seems like your attention is split.

[polar marten]

the min is 0

scale is lambda

[unkempt swallow]

please write the example

[vestal arch]

i mean i don't think they're really going to go for integrating their own functions given the lack of confidence with math that theyve stated

[polar marten]

i know how to translate what you want into statistiquese. but. if you just asked chatgpt to author this for you from scratch, it probably would succeed

[polar marten]

seriously listen to me and ignore that stuff

it just isn't correct

anything you want to do something random. you know, there's what you want to achieve with gameplay. i already told you the best way to do it is to create a deck, and replace the cards after you draw.
but if you don't want to do that, the thing i am describing is basically the same process

[unkempt swallow]

from what i read i think you both are saying the same thing but you are saying their solution is wrong

[unkempt swallow]

this means nothing to me

RandomExponential rnndn = new RandomExponential(0,0.025f);

i thought this would be correct but it isnt

[polar marten]

okay, well you wrote 0.025f, which is 1/40

i think you should maybe take a breather

or ask chatgpt to do it for you. it will give you a correct answer. buy plus

[unkempt swallow]

so if i want 100 to be the max i use 0.01?

[polar marten]

no.

[vestal arch]

why are you here to sell chatgpt lmao 😂

[polar marten]

🥺

[hexed pecan]

It's so absurd

[polar marten]

if you want to have a very specific behavior, generate a deck of 100 cards with the weights written on them. then when the user draws, do not remove the card from the deck, just shuffle it again.

[vestal arch]

@unkempt swallow you wanna have a try with an animation curve?

[unkempt swallow]

yes please

[polar marten]

you can't turn an animation curve into a histogram...

it doesn't work the way you think it does

you would just be doing the process of making the deck

and drawing from it

[vestal arch]

you wanna explain?

[polar marten]

you drew a histogram. yo ujust don't know that you drew a histogram

[vestal arch]

yeah

well no

not really

actually no it wouldn't be a histogram

[polar marten]

look at the title of the chart i got out of chatgpt. i asked for a histogram. an animation curve evaluated at time t, where teh aniomation curve is a histogram, is telling you the frequency of that value

see. that's because you're all confused. he was indeed drawing a histogram. that is a PDF...

you can't just draw a PDF and sample from it.

[craggy veldt]

i dont think recommending gpt is wise here

[vestal arch]

one sec

[polar marten]

you would have to do another step. which is exactly the same thing as what chatgpt did, which is generating a bajillion samples. and then you're back at square one

🥺

listen anything is possible!

you are overthinking this

[polar marten]

can you just copy and paste this with backticks?

i can't edit a screenshot for you

[vestal arch]

just gonna test it first, since it wasn't my idea lol

[polar marten]

don't waste your time...

@unkempt swallow everything you need is directly in front of you

[unkempt swallow]

i cant see it

👨‍🦯

[polar marten]

can you copy and paste your code

into backticks @unkempt swallow

just do that for me

[unkempt swallow]

            RandomExponential rnndn = new RandomExponential(1,0.01f);
            float thenumber = rnndn.Get();
            testlist.Add(thenumber.ConvertTo<int>());

this is my current code

[north hatch]

Does anyone know how to make for exemple i pick up a key and then lets say when i turn around a jumpscare plays whats it called?

[latent latch]

well, you're triggering something by picking up a key, but the jumpscare to happen you'd probably check if it's currently in the viewing frustrum after spawning it

@north hatch

[polar marten]

i really think you should pay for chatgpt plus

you are in a good place and very aspiring

it will help you with a lot of instruction

[north hatch]

okay

[unkempt swallow]

i am beyond poor bro

[polar marten]

well i think the free version also works well

certainly well enough

[north hatch]

cause im making a story game and i need it

[polar marten]

this is a simple enough problem for o1 mini

[unkempt swallow]

why is there a while loop

[polar marten]

that's what it means to redraw

[unkempt swallow]

why do i even have to redraw / discard

[polar marten]

this stuff will get easier

[unkempt swallow]

thats like wasted computer power no

[polar marten]

because that's what it would be in real life

hmm. well the last thing i'll say is the general approach to these problems is

try to do it how you would od it if you were implementing a board game

[vestal arch]

it doesn't matter at this scale, computers are really fast

[polar marten]

in cardware. then you can translate your cardware board game rules into code. it will be a lot easier

that's why i said, make a deck of a 100 fish. then shuffle it. then look at the top card. that's your fish. then shuffle it and look at it again for the next fish

[latent latch]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Renderer.OnBecameVisible.html
There's a good call for it, but you'll want to make sure you only spawn it after picking up the key

[polar marten]

does that make sense?

@unkempt swallow so think with board games first.

[unkempt swallow]

you dont know if i plan to catch 9 decillion fish per second tho

using this i get only 100, 100 times

[vestal arch]

no computer would be able to render that, this part is not going to be the bottle neck lol

[polar marten]

i can't ad hoc program for you

in the discord window

i've told you a bajillion times how to do this

i've even shown you a chart that gives you what you want

[unkempt swallow]

using the code you posted i get 100 times the result 100

[polar marten]

i know.

i think i have exhuasted my energy on this, i'm sorry.

[unkempt swallow]

@chilly surge please 🙏

[polar marten]

i didn't want to program into the discord chat window

you still are responsible for writing your own code

[thin aurora]

Make a thread

Jesus

[polar marten]

i think you are best served by asking chatgpt

[craggy veldt]

wtf

[latent latch]

didnt we get here because of chatgpt

[polar marten]

no, but the user has received a lot of very specific guidance

[vestal arch]

yeah ok the animation curve works fine as far as i can tell

[polar marten]

and ultimately wants a snippet of code that "just" does what he asked for

[latent latch]

animation curve is bff

[chilly surge]

Here's an example math:

Let's say you want to randomize a fish's weight in the range 100 kg to 200 kg, with a customizable curve. Let's say you mess around and end up with a curve like y = 0.2 * x + 100 and you feel like that's the one, now here's how you would do the randomization part:

• Integrate y = 0.2 * x + 100, you get a result of 0.1 * x^2 + 100 * x + C.
• Plug in x = 100 (your lower bound), you get 11000 + C.
• Plug in x = 200 (your upper bound), you get 24000 + C.
• That's it, in your code you can use Random.Range(11000, 24000) to get a random number.
  Let's say the randomizer gives you back 20000, now you need to calculate what kg of fish it corresponds to:
• You solve the equation: 0.1 * x^2 + 100 * x = 20000, which gives you x = 170.8, so player fished up a 170.8 kg fish.

This math uses y = 0.2 * x + 100, but the same calculation works for any curve you want, so you can adjust the curve to however you like and plug in the same math to randomize fish weight according to it.

[polar marten]

🥺

the animation curve by itself doesn't solve th eproblem. you still end up sampling it...

there are

a million ways to do this

i'm not saying one is right or one is wrong.

[vestal arch]

and it doesn't involve any math

[polar marten]

listen to yourself

[vestal arch]

im not saying it's better

[polar marten]

lol

i know i know

i think the user got what he needed.

[latent latch]

imagine having to go on desmos and visualizing your curve

[vestal arch]

it's more achievable for kinami

[latent latch]

no one has time for that

[polar marten]

yeah... we'll see about that

[vestal arch]

because you can just draw something like this and not do any math

[polar marten]

yeah...

if you are just evaluating that curve with random t 0 to 1

it won't be correct

is that what you are doing?

[vestal arch]

yes

why wouldn't it be correct

it's not a pdf

[polar marten]

what is it exactly lol

[hexed pecan]

You did say that others are wrong and to ignore them though 😆

[vestal arch]

it might be a cdf, idk 😛

[polar marten]

lol exactly

you basically drew a random curve!

[vestal arch]

but you don't need to know any math to use it

[vestal arch]

isn't that what kinami is asking for though?

[polar marten]

it's not hard to turn the exponential dist pdf / histogram into a curve that works the way where you draw it and sample it, but they're not the same!

you need to know math to do that transformation!

[vestal arch]

do you need to do that transformation though?

[polar marten]

well...

[vestal arch]

exponential curve might not work in the general case anyways lol

[polar marten]

you know, go ahead and try to make that histogram lol

i know

[vestal arch]

why should i?

[polar marten]

it's okay. we've spent enough cycles on it

because the histogram is how you measure the behavior

[vestal arch]

sure

[polar marten]

it's how you know if you did it right

@chilly surge you can draw a curve that is a histogram. but the way to use it is to create a "deck" of "1,000" cards, each with a value written on it from animationcurve(random.random). then shuffle the deck, then draw a card, then discard thd eck.

does that make sense?

it's not enough to just call animationcurve(random.random)

[chilly surge]

Sorry but I don't think you even read what I've written, it has nothing to do with animation curve.

[polar marten]

if you want to draw a curve that is the inverse of a pdf, you can, but that is hard

[hexed pecan]

It's a video game, I don't think anyone notices if the random distribution uses a perfect math formula or if it's sampled from an animation curve

[polar marten]

okay, i think what's confusing about this is, what does the value of the curve represent? what is x, and what is f(x)?

before you take any of the other steps

so what if i draw a line between 100kg and 200kg. what does it mean?

succinctly

before these steps with integrations or whatever

which, btw, is just doing the histogram, and sampling from it. this is valid! i sort of know what the curve means. there are lots of valid approaches. but at least say succinctly, what does x and f(x) mean

[chilly surge]

^ It's been clarified long ago.

[polar marten]

i used the chatbot to create the distribution he wanted

[polar marten]

this makes it sound like f(x) is the probability of drawing x?

that's a pdf then, yes?

you actually want the inverse of the pdf, not the integral

[polar marten]

inverse meaning, f_inv ( f ( x ) ) = x

the integral wouldn't make sense

[vestal arch]

does exactly what i intended it to do

[chilly surge]

🤦

[polar marten]

well we can only reason about stuff that makes sense with real math no?

[chilly surge]

I'm done with this conversation, OP got what they asked for.

[polar marten]

there's a reason that's what people use to communicate things

[vestal arch]

this isn't a math server lol

[polar marten]

it is now!

you better start believing in math if you wanna make games!

[vestal arch]

here we get stuff done, unlike mathematicians

[polar marten]

lol

i appreciate that this was a stylized comment. but c'mon guys. if you want to elevate above the chatbot, you should adhere to like, real educational stuff

as much as i love being admonished for telling a "juster" kind of user who "just" wants an answer for using a chatbot. well... it's fun to talk about what's really going on

if you want to draw a pdf using an animation curve, that is, the user needs to draw a curve in the eidtor that looks what he drew earlier, you would need to compute the inverse of it

that's just the approach. you wouldn't take the integral

[chilly surge]

If you believe my math is wrong, you are welcomed to sample according to the math I've given above and see for yourself that the resulting histogram does match the curve given.

[polar marten]

i just punch into google "how to sample from pdf" and the answer is "inverse of pdf"

which isn't generalizable for something like gaussian, which you can see for yourself in all the implementations

[thin aurora]

Maybe you guys should request a math-and-procrastination channel

Instead of here

[polar marten]

i can't believe people are coming out as anti-math!

seriously everyone will write much better games if you learn this stuff

i've been talking for ages about modeling it with decks. that's really good for designing games too!

[vagrant blade]

This is beyond Unity related now, move on.

[chilly surge]

Good thing is I don't need to Google to know my math is right and is verifiable by running a simulation yourself. But yes I shall stop here.

[vagrant blade]

If you want to continue debating this, you can make a thread.

[vestal arch]

anyways, @unkempt swallow, if you're still interested in using an animation curve;
with a serialized AnimationCurve, you can edit the curve directly. it would basically be a mapping between the Random.value and the output value.
for example, #archived-code-general message with this example, the min value is 5, there's a high chance to get values around 30 (the flat area), there's a 75% chance to get an output under 50 (consider the value at t=0.75)
histogram for that demo curve: #archived-code-general message

when drawing the curve, make sure to edit the start and end points to be at exactly 0 and 1, and set the min/max that way as well (right click the points > edit point)
right click the points to set the tangents to weighted to freely control the curve, and you can add more points as needed
to sample it, you would do curve.Evaluate(Random.value)

[viscid plaza]

Movement inside car

[unkempt swallow]

i understand everything besides the last thing you said, i think it contradicts what you said before?

when drawing the curve, make sure to edit the start and end points to be at exactly 0 and 1, and set the min/max that way as well (right click the points > edit point)
right click the points to set the tangents to weighted to freely control the curve, and you can add more points as needed
to sample it, you would do curve.Evaluate(Random.value) 

can you rephrase this

[vestal arch]

which part

and ive said a lot of things, what exactly contradicts what?

[unkempt swallow]

i think the animation curve does nothing at all, because you still use Random.Value, so lets say i get 0.8 which on the curve would be at .8? what is the point of the curve, i dont understand

0 to 1

ohh time is on the left

[heady iris]

the input is on the X axis

the output is on the Y axis

[unkempt swallow]

i see yeah

[vestal arch]

animation curves are normally for, well, animations, where the x axis is time, and the y axis is what to do

[heady iris]

I use animation curves for this kind of thing pretty often

[vestal arch]

so if you get 0.8, you would sample at that "time", and get ~0.3

[unkempt swallow]

ye

this is great and i think i will use this often, exactly what i wanted
what my friend helped me with is this now

    public float decay = 1.5f;
   
    public float GetRandomRarity()
    {
        
       float randomValue = Random.Range(0f,1f);

        float rarity = -Mathf.Log(1 - randomValue) / decay;

       return rarity * 10;
      
    }

which gets me basically values up to infitiy lmao with the option to adjust

ill stick with the anim curve tho, i like the numbers more

in 100 rolls, only 5 were above 0.5, perfect

ty ty

[stuck harness]

If I am going to use steamworks inventory system thing later for my cosmetic stuff, is it smart to use like scripteble objects and save them in some way until I get into steam works? or should I make it in anther way for a more smooth transition?

[polar marten]

there are a lot of good options. i suggest finding an inventory and cosmetics management asset store asset that supports steamworks

[kind nymph]

ok so this code was ORIGINALLY made to apply to transform.rotation.z and not rigidbody2.rotation so i switched it to rigidbody to comply with physics instead of bypassing it by changing from Quaternion.Euler() to rigidbody2.MoveRotation(). It kinda works but once angle reaches 180 it snaps to -180 and vice versa. If this isn't the right way to do this then I'm not surprised but unfortunately I don't know the right way (why does rotation have to be so complicated)

private void AimMouse()
{
    Vector3 mousePos = Input.mousePosition;

    Vector3 objectPos = Camera.main.WorldToScreenPoint(transform.position);
    mousePos.x = mousePos.x - objectPos.x;
    mousePos.y = mousePos.y - objectPos.y;

    float angle = Mathf.Atan2(mousePos.y, mousePos.x) * Mathf.Rad2Deg;
    Debug.Log(angle.ToString());
    rigidbody.MoveRotation(Mathf.Lerp(rb.rotation, angle, 0.05f));
}

[pulsar plinth]

hello guys
sooooo I've been trying to find the solution for this problem, but haven't been able to
I'm creating this one pixel art 640x360 game and I used to be making it in Gamemaker 2 since it was the engine I used to use but the project's code became complex really quickly and now I've needed to transition into Unity if I didn't want the game's specs to be ridiculously high. In GM2, sprites can be rendered through a single function which does the job, however it seems like the only way to render sprites in Unity is by using the sprite renderer component but this doesn't allow an asset to render more than 1 sprite at a time which would be very useful to create many things.
TL DR: I would like to know if there's a function which renders sprites, thus allowing more than a single sprite to be drawn with a single asset instead of having to create an asset with the sprite rendenr component for each sprite

by the way, despite being a complex project its camera always only displays a 640x360 slice of the game so it shouldn't be problematic to use a single game object for each sprite since I'll use a rendering deactivations for offscreen regardless, it just isn't ideal

[steady bobcat]

you use many game objects with sprite renderers to render many sprites, just how it works in unity. Very normal!
Unity has many things to optimise drawing many sprites, make use of spritesheets where you can.

Look into particle systems too

[pulsar plinth]

I see

I'll make sure to

thanks btw

[kind nymph]

if you mean can you render multiple sprites at the same time with one SpriteRenderer then refer to what the guy above me said, but if you just mean rendering different sprites with one SpriteRenderer then that's definitely possible, one method is to the SpriteRenderer's sprite directly at runtime by referencing another sprite

public class Example : MonoBehaviour
{
    public Sprite spriteA; // The first sprite
    public Sprite spriteB; // The second sprite
    private bool spriteToggle; // Whether to use the first or second sprite
    private SpriteRenderer sprRend; // The GameObject's SpriteRenderer Component

    void Start()
    {
        sprRend = gameObject.GetComponent<SpriteRenderer>(); // Get the reference to the GameObject's SpriteRenderer Component
    }

    if (spriteToggle) // If spriteToggle is true
    {
        sprRend.sprite = spriteB; // Set the SpriteRenderer's sprite to spriteB
    } else // Otherwise
    {
        sprRend.sprite = spriteA; // Set the SpriteRenderer's sprite to spriteA
    }
    
    /*
      Toggles the sprites. You would need to call this elsewhere at runtime by getting a reference to this GameObject's Script's Component, and then doing Example.ToggleSprite(). Alternatively you can Invoke the function with a callback from a button or similar
    */
    public void ToggleSprite()
    {
        spriteToggle = !spriteToggle;
    }
}

funnily enough im also porting a GM2 game to unity so if u have any other questions i (might) be able to help you

[pulsar plinth]

I did find out a function which does exactly that
Graphics.DrawTexture()

[west drum]

Can somebody help me with this code i cant find the solution. I want it to do a dash with an animation of dash. The dash was pretty ez but after the dash it keeps itself in that animation and is in the last frame until i change the state so if i move it works again but else it stays in dashstate

[steady bobcat]

drawing meshes this way is a good idea if you have many thousands to draw but for normal games its not needed

[pulsar plinth]

ohh I see
GM2 is great for getting into game dev but it does have a great amount of limitations and badly optimized ends, unfortunately

[pulsar plinth]

normal, as in like, a default amount of effects and sprites?

[kind nymph]

unless you need to draw tens of thousands of textures and sprites at the same time u dont need to bother with it i think is what he meant

[steady bobcat]

its going to be different per game. If in built solutions dont work and profiling confirms the problem is too many game objects/ poor batching then its worth looking at code only mesh drawing.

[polar marten]

what are you trying to do? is this a top down adventure game with a rigidbody based character that you move using point and click?

[polar marten]

use the built in sprite renderer and its toolset

absolutely do not use Graphics.DrawTexture at this stage

for a 2d game

that you have barely started writing

even for thousands of sprites

[pulsar plinth]

but what are the cons of DrawTexture, exactly?

[polar marten]

your computer is drawing thousands of sprites right now right in front of you (the text glyphs). trust me. you should use the sprite renderer

[polar marten]

you will be reinventing SpriteRenderer.

[steady bobcat]

unless you are doing vampire survivors level of sprites then you probably dont need it

[polar marten]

vampire survivors uses sprite renderers!

[steady bobcat]

oh i know. i got to speak to one of the devs last halloween at their party 😄

[polar marten]

you just don't need it period

lol

[pulsar plinth]

what's the problem in that?
I've reinvented all mechanics until now lmao
my game literally requires its own physics engine and collision logic

[steady bobcat]

I have a squishy garlic 🧄

[polar marten]

okay. what if i told you graphics.drawtexture is slow

[kind nymph]

it's top down but it's not point and click, it's a 2D space game.

it's not exactly physics based it just uses the linearVelocity attribute of Rigidbody2D so I can have acceleration and deceleration without any of the complicated transform manipulation business.

previously AimMouse() used to work with transform because it was bypassing physics but now I'm changing it so it doesn't do that and it has resulted in unexpected behaviour (as many abrupt conversions do)

[polar marten]

it is always going to be slower than spriterenderer

[steady bobcat]

vampire survivors has a port of the old engines physics engine (from the old js engine) as they needed it to be exactly the same
but due to perf issues they stagger some things on different frames.

[polar marten]

if you want it to feel very physicsy you can use a joint (like a spring joint) and connect the rigidbody in a bunch of clever ways to a transform that follows your mouse to it

[pulsar plinth]

ah, right

[polar marten]

this will give you physics and a nice framework for experimenting with controls if that's your goal

[pulsar plinth]

hmm, is vampire survivors really done using sprite renderer?

[polar marten]

yes

110%

why wouldn't it? why assume that something right in front of you would be slow

[kind nymph]

nah literally all i need it to do is rotate towards the mouse using the rigidbody, I don't plan on having it feel very drifty or anything since it's supposed to be paying homage to a game I used to play ages ago and that game didn't have very drifty space physics either

[heady iris]

unity can reason about all of your sprite renderers at once

[pulsar plinth]

I've gotten used to writing everything from zero
as I've said, the game already has its own physics and collisions mechanics, not using components at all due to optimization and control matters

[heady iris]

unity can't reason about a bunch of DrawTexture calls

[polar marten]

hmm. okay listen. you aren't optimizing things. i mean it's unknowable if you are

it might feel that way

and i get it. it matters, something that feels true is true

[kind nymph]

you may want to change that, components are basically unity's lifeblood .-. (you can work around them but i really REALLY recommend you dont)

[polar marten]

but you don't actually know

come at this with an open mind

keep chugging along

you can go ahead and use graphics.drawtexture. nothing bad will happen

if that makes you want to work on your game.

[pulsar plinth]

though, as I've also said, the game will not be cluttered with sprites in each frame like Vampire Survivors
so I'll sprite renderers instead

[polar marten]

if you are looking for validation, go for it

[pulsar plinth]

(unless I notice optimization problems, then I'll have to get deeper into meshes and etc.)

[polar marten]

choose whatever will make you excited to work on your game

[polar marten]

unfortunately mouse driven rotations with rigidbodies are very tricky
i would use the appropriate joint that can transfer the rotation with very high "Stiffness"

that's how i do it in all my games

so that it's non kinematic but still feels very snappy

[pulsar plinth]

I could show the game to prove the point, but to sum it up it has massive levels with entities that can interact with any other entity and deactivating entities outside the screen would be non-ideal (I think, I'm considering splitting levels into several rooms to make that more manageable)

[polar marten]

computing the right amount of angular velocity such that the rigidbody very stiffly rotates towards the mouse and abruptly stops rotating when it is facing the mouse is exactly as hard as implementing a framework for joints

@kind nymph does that make sense?

[kind nymph]

thinking about this and skimming through the spring joint documentation actually made this seem a lot more appealing

[polar marten]

okay cool

[kind nymph]

of course I would need to tweak the settings so it doesnt bounce too much

but thank you for the insight 👍

[polar marten]

if you are excited about stuff like this, use ECS

[pulsar plinth]

I looked it up but it costs
plus I don't think my game is that complex either

[hollow anvil]

does anyone know if i can single out and debug a script ran by an object that other objects are sharing that script? For an example if have a bunch of enemies running their own enemy script. How can i debug one particular enemy and its script ?

[steady bobcat]

if using a debugger you can set conditions to check on breakpoints. I often do something like check for a local var value or you can even do gameObject.name == "blah"

if logs, you can add a context object as an arg to Debug.Log: Debug.Log("foo", this);

[hollow anvil]

i see ! i didnt think of using conditional break points to do that, though is there a faster way to single out the game object for debug ? The bug im trying to pin down happens semi often and i would prefer not to having to manually change the gameObject name everytime

[steady bobcat]

well unless you can create a condition that identifies this object then its not going be easy
Sometimes its wise to add a check in code manually somewhere to detect a bug so you can log it and even pause the debugger.

[hollow anvil]

yeah the bug im having doesnt really cause run time error but just some logic error that is causing animation issues for my objects. I guess ill just stick to conditional break points. I worked with Unreal for a little bit and it was much simpler whenver I wanted to take a look at a specific object to debug. Im too spoiled from that lol.

thanks for the help!

[heady iris]

or, if you haven't figured out how to use conditional breakpoints yet, you can just throw in

if (someCondition) {
  Debug.Log("Put the breakpoint here.");
}

[hollow anvil]

no thenks, iM tOo LaZy

[steady bobcat]

dunno how you did it in unreal but its not a unity specific issue.
it is sometimes better to just add an if for the breakpoint condition as conditional breakpoints can reduce framerate

[stuck harness]

you have any tips super hard to find

[simple void]

This isn't a very technical question more so design choice. Say I have a lot of instances of some entities(e.g. animals) roaming around all using the same material&shader that displays vertex colors. I want when they are damaged to display a different color, like red. Should I quickly switch out the materials? Create new material properties? Have a buffer for all instances and also detail which entity instance a vertex is in its vertex information passed to the shader so I can just change the buffer's information?

[heady iris]

That depends a bit on which render pipeline you're using

Material property blocks would be my go-to in the built-in RP

that lets you override specific properties on each renderer

In the scriptable render pipelines (URP and HDRP), the SRP Batcher only works if you aren't using material property blocks

you're intended to just create a material instance for each renderer

(by accessing renderer.material)

If you're rendering a huge number of non-skinned meshes, you could do instanced rendering. In that case, you'd want to use material property blocks again

[simple void]

Thanks for the input, I’m using URP for skinned meshes(they’re animated), I want the render pipeline to avoid creating a draw call for each instance, in terms of performance I think it’d be much more preferred if I just inject the instance index through as a vertex property to lookup in a buffer. But that is a pain to setup obviously.

[heady iris]

You can't avoid the draw calls, AFAIK -- you're drawing many different meshes (after skinning)

but the SRP Batcher can give you better performance e

https://docs.unity3d.com/Manual/SRPBatcher.html

[simple void]

I see, I guess quickly switching the material isn’t that bad, if I just have two shared materials for each state. Just wondering whether there was a more correct way

[heady iris]

It should be roughly the same to have:

• one material for "normal" and one material for "hurt"
• one material for every single renderer

I'd guess the former is better, but the SRP Batcher can handle both

[simple void]

That’s fair I suppose the difference is pretty negligible, this whole conversation is pretty nitpicky

[edgy ether]

dunno if this should be in general or advanced coding but here's what i wanna do.

i want to make an editor script that accesses the selected imported textures from the project and allow me to assign secondary textures to them via script.

but i dont know if it's possible to access and set the secondary texture in the project.

is it possible to get and modify this information in script instead of manually clicking one at a time?

i was planning to make a script to set them all in bulk based on my naming convention

[cosmic rain]

Wdym by "secondary textures"? I'm not sure there's such a concept in unity or gamedev in general..? In relation to textures.

[heady iris]

https://docs.unity3d.com/6000.0/Documentation/Manual/sprite/sprite-editor/secondary-texture/secondary-texture-landing.html

It's a sprite thing

It lets you associate multiple textures with a sprite

I also completely forgot about that and had to google it :p

[edgy ether]

yeah, sometimes stuff like specular maps, emissions and etc

[heady iris]

A sprite is just a reference to a texture + where to sample from it

[edgy ether]

yeah, but basically what i want to do is get code to access the ability to add/change the secondary texture so i dont gotta manually add it in for hundreds of textures

[heady iris]

I'd ask about this in #↕️┃editor-extensions . I suspect you just need to look at an example of a Sprite with secondary textures to figure out the correct serialized properties to look at

I see a secondaryTextures property in here

(I copy-pasted a sprite sub-asset so that I could look at its actual serialized data directly

[edgy ether]

i see, so it probably would b e about getting the file and guid and type to add it

[cosmic rain]

It seems like you can pass them in when creating the sprite:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Sprite.GetSecondaryTextures.html
Refer to the example on the page.

[heady iris]

Ah, there you go

Now, if you're trying to modify the secondary textures for sprites produced by an importer, that's a different story

I'm not really sure what you'd need to do there

maybe an asset postprocessor..?

[steady bobcat]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/TextureImporter-secondarySpriteTextures.html

[edgy ether]

hmm, well i guess i have to look into any possible access to the texture importer scripts..

[steady bobcat]

getting an importer for an asset is often the best way to modify it

[heady iris]

Would you do that in a postprocessor?

I'm still pretty uncertain about this stuff myself

[steady bobcat]

Last time i did this i just had a menu item to go over many sprite sheets to change some settings on their importer

[heady iris]

how do you get at the importer?

[steady bobcat]

I think you use this and cast it to the correct type
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/AssetImporter.GetAtPath.html
make sure to set stuff as dirty and save the changes after

[heady iris]

ooh, okay

that makes sense

changing importer settings in a postprocessor wouldn't make sense

[steady bobcat]

an example from something i did a while ago:

TextureImporter texImporter = (TextureImporter)AssetImporter.GetAtPath(assetPath);
if (texImporter != null)
{
    EditorUtility.SetDirty(AssetDatabase.LoadAssetAtPath<Texture2D>(assetPath));
    TextureImporterSettings texsettings = new TextureImporterSettings();
    texImporter.ReadTextureSettings(texsettings);

    //9 is the custom alignment mode
    if (texsettings.spriteAlignment != 9)
    {
        EditorUtility.SetDirty(texImporter);
        texsettings.spriteAlignment = 9;
        texsettings.spritePivot = newPivot;
        texsettings.ApplyTextureType(TextureImporterType.Sprite);
        texImporter.SetTextureSettings(texsettings);
        texImporter.SaveAndReimport();
    }
}

i had issues with shit not saving hence the weird dirty 😆

[edgy ether]

this looks interesting, thanks. i'll mess with this another time to see if i can get the result im looking for

[pearl burrow]

hello guys. I've made up a level manager/quest system and all the quests are stored in a list so when i finish the x quest i just go to the x+1. all the quests are scriptable objects (structure in the image). In my json savedata i just save the index value corresponding to the element in the list so i can retrieve easly at which quest i am when i start the game. So all good the "main quest" is done. But i also want to have the possibility to have more quests going on (so sidequests). What you suggest to save in the json for other quests going on (can be multiple ofc). A list of the indexes of a list filled with the side quests? Seems an easy answer but i cant find a solution i like!

if i save all the possible sidequests in a list i could easly access them and save the index of all the sidequests going on. but i dont know why it sounds wacky and there is a better way

[wicked scroll]

saving indices is very delicate because if you update your game, they might drift, and it could break people's saves (which maybe is fine! up to you)

you could auto-generate some kind of UUID for each quest and use those to reference each quest uniquely. In practice, I recommend giving them unique string names because it will make your life easier keeping track of everything.

[pearl burrow]

do you mean unique string names that i write. so i load all the quests from the resource folder, use a dictionary of strings and retrieve the quest?

[wicked scroll]

yep

[pearl burrow]

sounds good indeed

so i can also attach the quest to where i need in the scene instead of numbers

[wicked scroll]

I would recommend loading them from some kind of 'active quests' object so that you can have quests included which aren't 'live' yet, but it doesn't matter that much

[pearl burrow]

to access the list

tysm

[wicked scroll]

if you want to do this, you might want to make your quests individual ScriptableObjects

[pearl burrow]

yes they already are indeed

[wicked scroll]

nice, there ya go

[pearl burrow]

and how would you deal with the rewards then. For now for the main quest i have a big class with switches that gives rewards according to my needs

[wicked scroll]

one advantage to readable string IDs is that for debugging it's nice to be able to do stuff like /grant quest tutorial_combat_1

[wicked scroll]

if each quest is an SO, you can define the rewards on there

[pearl burrow]

wait i show you what i mean

which is probably ugly

[wicked scroll]

my eyes are too pure to look upon anything ugly

[pearl burrow]

behold

rewards can be of anything

i dont really understand how a scriptable object can do that

using a prefab with a script that does only that probably?

[wicked scroll]

yeah, and that might be valid as well

what I would do is define my rewards as data

they can't really be anything

[pearl burrow]

yeah sure

[wicked scroll]

they can be unlocking a skill, or setting an element, or adding an element amount

and you can define those in a list of rewards with an enum or something in your SO

[pearl burrow]

so i could put in there some flags to represent which reward is it and with some editor scripting making it pretty

[wicked scroll]

yep, and then somewhere you'd map that enum to the actual code to 'grant' that reward

[pearl burrow]

when i do these things i always think "why do i need some value when it may be not used". thats why sometime i get stuck..

for example in my scriptable object i have the float Distance and the list of objectives to complete

which represents two way to complete the quest

[wicked scroll]

sometimes you can define things abstractly enough, where it's like 'a type and a value' and then you don't have redundancy

[wicked scroll]

the answer is 'because your code is simpler if it can assume that values always exist'

[pearl burrow]

ahaha yeah good one

so i should eat what i have and dont worry for now. there will be time to polish

[wicked scroll]

you can have different 'configuration' objects that you switch between in the editor based on the type of quest selected in the dropdown

the thing is, 'configuring your game' does not need to be the same as 'running your game'

[pearl burrow]

yeah man, to making it simplier to program youre making it harder to finish

[wicked scroll]

so if it makes sene to have some ugly extra data in there at design time, but then at runtime you build up some objects from that data which are simpler to work with and only have the pieces you need, that's good

[pearl burrow]

alright thanks again, ill delete this class full of switch lmao

[wicked scroll]

yeah generally if it works then go for it, but you already have an object for each quest so it would feel much better to me if the rewards were defined on there too

[pearl burrow]

yeah i always thought of it but never did it

cause in my mind "what if i need that, or that! or this!!"

[wicked scroll]

of course, sometimes the rewards are highly contextual and it doesn't make sense to say 'this quest always gives this reward', in which case maybe having some systems which handle reward distribution at a higher level like you have make sense (but it would still be good to use tags and things to organize them instead of a per-quest lookup)

[wicked scroll]

the eternal struggle

[pearl burrow]

oh one last question

[wicked scroll]

I've landed on 'write only the code you need, only when you need it, and keep it as easy to delete as possible' 😄

easiness of deletion is a one of the few good code quality metrics

[pearl burrow]

as you can see in the ugly rewards method im using some managers to update the rewards. those are actually services (im using a service locator). In this case its best to attach prefab for the rewards right? cause i dont know if its a good thing to use it in scriptable objects (if its possible too)

sorry i mean, im referencing the managers directly. but i might need to use the service locator

[wicked scroll]

it's not something I'd worry about on a solo project

C# is really easy to refactor

service locator is probably technically better but I don't expect it will matter, and if it does it's pretty easy to go through and update those

folks have differing opinions for sure

[pearl burrow]

yeah ok, ill start from somewhere for now

also by going to sleep

bb and thanks

[flat marsh]

Hi! I'd love it if someone could give some of my code a review. I'm interested to know if there is a more efficient / better way to approach this problem. Please give all feedback as it will help me become better :D

Here is the link: https://paste.mod.gg/txnqnxukazyj/0

For a bit of context, this is a almost done piece of code that I've written in the past couple of days. It is for a skill tree in unity (by almost done I mean its just missing some of the skill effects, I still need to code those but the framework is done). I've commented the whole thing so hopefully that should help

Here is also a screenshot of what it looks like in unity (visual WIP, I don't have art for it yet)

Each smaller white square is a skill node, the larger one is purely for visuals and the cancel button explains itself

Here is also a screenshot of what the inspector for the script looks like:

Skill TXT is just where I assign what visual elements explaining the skill tree I want set active

Thanks!

(Also I'm sorry if this was too large)

[mellow mural]

You could use switch cases for checking your enums instead of a bunch of if else statements

[plucky inlet]

I am wondering, why you always use FindGameObjectsWithTag instead of handling them in script

[plucky inlet]

Oh yes, I agree with File_Missing, def. look into switch cases and also try not to hardcode values in your script for example increasing health. That should come from some kind of SO or list or database in best case.

Imagine you want to extend your skill level and experiencepoint checks to way bigger numbers. you do not really want to mess around with x amount of if statements to get the correct amount of health, stimlevel or whatever all those values are 😄

[leaden solstice]

Why do you have region for every single method

[flat marsh]

Thanks! I think I might actually look into databases now that you've suggested it :D. As for not using switch statements..... I didn't want an if statement inside every switch case. I did try to use them originally but you cant have another condition in the same line as the switch statement (at least that is my understanding of it) and I need to check multiple conditions to allow the skill to become active.

[flat marsh]

Its looks more organised that way XD.

[prime lintel]

Hi all, is there a way to properly search for a tag where there is only a single instance of the gameobject with such a tag per scene? But only when the scene is loaded and the old one is unloaded?

private void HandleSceneChange(string sceneName, bool showLoadingScreen)
{
    _InterfaceEventChannelSO.RaiseEventLoadingScreen(showLoadingScreen ? true : false);
    new Task(SceneChangeLoadAsync(sceneName, OnSceneLoaded));
    _InterfaceEventChannelSO.RaiseEventLoadingScreen(false);
}

private void OnSceneLoaded()
{
    CameraManager.Instance.UpdateFollow(GameObject.FindGameObjectWithTag("Player").transform);
}

private IEnumerator SceneChangeLoadAsync(string sceneName, System.Action callback)
{
    AsyncOperation asyncLoadScene = SceneManager.LoadSceneAsync(sceneName);

    while (!asyncLoadScene.isDone)
    {
        yield return null;
        callback();
    }
}

my current problem is that it finds the tag of the player from the previous scene in editor mode and returns null in a dev build

[leaden solstice]

You should make this data oriented so you can expand it (such as adding another level) without changing code

Also should try avoid using singletons

[flat marsh]

How come?

[plucky inlet]

Yeh the problem lies within your hardcoded stuff. You need to think of it in a more generic way. So a skill tree is a list of skills in a hierarchical order for example. So you could have skills referencing child skills or whatever fits your needs. And then loop check your enums to get the right values back for all your stuff you have in there. So bascially your if loop hardcoded would become your hierarchy in inspector for testing and later in whatever dataformat you want (json preferably or just a simple SO yada yada)

[leaden solstice]

Because your code is hardcoded and impossible to add another character with own skill tree and experience etc

[flat marsh]

Ah. Ok. I will try to avoid using them in the future

[leaden solstice]

new Task with IEnumerator? what

Is that even compile or is that Task your own something

[prime lintel]

Solved: built-in function OnLevelWasLoaded(int) works

[prime lintel]

yes my own

[plucky inlet]

If there is only one, use the singleton pattern for that one

[leaden solstice]

Why

[plucky inlet]

lol, singleton hater cathei? 😄

[hexed pecan]

They aren't inherently bad IMO, this is just not a great usecase for it

[prime lintel]

i initially just got into unity at the time and coming from aspnet i didnt really do much coroutine work so I had no idea what i was doing tbh

but the code is sacred rn and on the backburner for cleanup

[plucky inlet]

but thats also not your question, right.

[leaden solstice]

If you're from asp.net you probably already familiar with dependency injection concept

There are libraries that supports it and you don't have to do "singleton pattern" shit

[hexed pecan]

This is preference.

[plucky inlet]

objectivity left the room, I guess 😉

[leaden solstice]

If you call bad code a "preference"

[plucky inlet]

Oh boy, we got it. you hate singletons.

[leaden solstice]

And you love it because you don't know how to properly avoid it? 🤔

[prime lintel]

ill probably look into it, i too also have a slight distate for singletons. but seeing as this is part of my portfolio for uni applications i would prefer to learn something that is easier to understand for my future teammates. i think dependency injection is lovely too but not for people largely without coding background at all (as the way it is for the program im aiming to enter)

[plucky inlet]

I do not love it. But it makes sense, if you have one player in the whole game (which I assume from his code of find by tag "Player"), to just have a static reference everyone can access at all times. But you do you and as you only raging and not really giving info about WHY you think its bad, I could not care less.

[hexed pecan]

I use it where it fits, I have no reasons to avoid it

[leaden solstice]

Have fun when your director want to support split screen.

[plucky inlet]

Splitscreen for a singleplayer game?

[leaden solstice]

Why not? You think "We want to add co-op game mode!" never happen?

Or "we want to let player control different character mid-game!"

[plucky inlet]

ohhhh, thats the reason? So starting a project with ALL possibilities to come is a profound way of going bankrupt. If there would be multiple players needed, a singleton doe snot make sense. But you are just rying to prove a point with arguments, that are flying by randomly. Again, I understand this as a singleplayer game, so singleton fits to this target. If his plan is to make it coop, thats another story and another way of doing things.

[leaden solstice]

Relying on singleton is simply making your code inflexible for no good reason

[hexed pecan]

And judging the whole pattern if someone misuses it, is like hating hammers because someone hit their thumb with it

[plucky inlet]

Its giving you access to one source of truth of a specific class, good reason for me. Imagine having a datamanager load stuff or return textures you can load dynamically. You gonna hate singleton there too, because what if we want multiple datamanagers? (which does not make sense)

[thin aurora]

The only issue I have with singletons is that everybody resorts to implement it with a static variable. I feel like having a general provider that provides shared instances works a lot better here

[plucky inlet]

But I get, that you are not a fan of it and thats fine with me. Still I would love to read a suggestion / solution how you do it, so I can learn something new probably. Honestly always interested in other ways of doing stuff, if its not filled with raging subjectivity

[thin aurora]

That said, rejecting singletons because you might need more instances is a very obscure reason. You can give edge cases for everything, but that doesn't mean an implementation is bad

Just make sure you're not tied to it. Singletons are fairly reasy to scale on

[leaden solstice]

Sounds like "I'll not make my code modular and I will rewrite everything when design changes!"

[plucky inlet]

Sounds like you continue with raging on me, so I step out of this conversation. No outcome for me here

[thin aurora]

If you have a main singleton provider that provides instances rather than a static variable everywhere then the code is very modular

[hexed pecan]

You can always make your singleton an interface and then swap out the implementation if needed
The reference needs to be stored somewhere tho

[thin aurora]

Which, by the way, is how .NET generally does it using its IServiceProvider pattern

[leaden solstice]

Singleton registered to a IoC container is fine. It is not "singleton pattern"

Which imply access from static instance variable

[hexed pecan]

I haven't seen good arguments against using a static variable

And no i'm not talking about static in general, im talking about the singleton usecase

You also can't always assume that everyone develops for a massive team

[thin aurora]

There's nothing wrong with it, it works fine for the majority of people

There's always a better approach, and like everything else it has its issues

[hexed pecan]

Give me a concrete example of an issue

I'm ready to be educated

[flat marsh]

Does anyone have any good resources where I can learn about databases in relation to unity?

[plucky inlet]

You sure, you want to go with databases right away? assuming you try to put your skilltree there?

For easier development to learn relations to data and your actual runtime object, I would go with some simple SO or inspector list to start off, testing around. Learning to serialise data from and to json. Database might be a bit too over the top to start off

[leaden solstice]

Are you asking for example of issue from using static instance variables?

[hexed pecan]

Yes, specifically for singleton access

[thin aurora]

Not to deviate from the path, but also think of using a file-based approach instead of a database. Pretty sure most games resort to that instead

[flat marsh]

Ok that's fair advice. Just from what I was able to look up now, databases are more for multiplayer games, however, my game is a singleplayer

[plucky inlet]

In the end, your skilltree could be only ONE field in the database returning an array or what not. But you just want that array right now to fiddle around with your skills 🙂

[torn solar]

void UpdateColors(Player targetPlayer = null)
{
    if (targetPlayer != null)
        playerList.transform.Find(targetPlayer.UserId).Find("Color").GetComponent<Image>().color = colors[(int) targetPlayer.CustomProperties["Color"]];
        
    HashSet<int> usedColors = new HashSet<int>();
    foreach (Player player in PhotonNetwork.PlayerList)
    {
        if (player.CustomProperties.ContainsKey("Color"))
        {
            usedColors.Add((int) player.CustomProperties["Color"]);
        }
    }
        
    foreach (GameObject color in colorButtons)
    {
        if (usedColors.Contains(colorButtons.ToList().IndexOf(color)))
        {
            if (color.GetComponent<Button>().interactable) color.GetComponent<Button>().interactable = false;
            if (!color.transform.Find("X").gameObject.activeSelf) color.transform.Find("X").gameObject.SetActive(true);
        }
        else
        {
            if (!color.GetComponent<Button>().interactable) color.GetComponent<Button>().interactable = true;
            if (color.transform.Find("X").gameObject.activeSelf) color.transform.Find("X").gameObject.SetActive(false);
        }
    }
}

i'm making a multiplayer game with photon pun where players select colors in the room, but when i'm updating the color buttons with this function, the buttons which are already claimed flicker (they become interactable and the X text on top of it gets disabled for a split second). how can i fix this?

[leaden solstice]

That the "this exists only one" assumption is hardcoded to your code. Already mentioned that if your player is referenced Player.Instance of such you cannot add another player without massive refactoring.

[flat marsh]

I mean its not too hard to add or subtract skills rn. To make a new skill, I just add an entry to one of the code paths (enum 2) , then add the else if statement under that branch in OnClickCheck(), and then I add what I want that skill point to do. Besides, before I actually made the skill tree I spent a while concepting out how I want it to work, so it should not be a huge amount of fiddling

[plucky inlet]

Until you are at a complexity and things start to break. Then you gonna hate yourself for not structuring it in a more dynamic way

[hexed pecan]

Yes yes, that's just singletons in general. I wouldn't use a singleton for a player in most cases.
I would probably use a singleton for an audio manager though, for example. This isn't related to the static variable access anyway however.

[flat marsh]

I'll look into it definitely, but for what I need right now I think my solution is ok. Thanks so much for all the advice though :D

[leaden solstice]

If you use dependency container with contexts you're just able to switch between singleton and non-singleton, not only implementation

[hexed pecan]

With the same logic, you would always use float[] instead of float in your code, "in case you need more later"

(not related to your most recent message)

[flat marsh]

One more question, based on that code that I wrote, how advanced would you say I am? I'm just try to gage where I am :D

[cold parrot]

If you ask that question you are a beginner.

[plucky inlet]

yeh, might be the best answer. you are advancing everytime you learn something. So how much "advanced" are you, I do not know, but you are missing some core conecpts that you still have to learn. Not really a question, someone can easily answer from one script 😄

[flat marsh]

What core concepts?

It's also relevant to what your audio manager requires. It might need reference to the output device, or the player so it can calculate distance from sound source and whatnot.
And if we want to expand the whole singleton assumption does not work at all on something like server or generic libraries, so why not be consistent.

[cold parrot]

Most people understand way less than they think they do and the more you understand the more you realize that you actually know nothing.

I am struggling with my UI I am coding with ui toolkit , my dialogue text pushes into the dialogue options below: https://pastebin.com/80wEC6gc

[hexed pecan]

I guess it all boils down to the complexity and needs of your project

Introducing people to new concepts or alternatives is totally okay, it just irks me when one says you "can't/shouldn't ever" use something, when it works for a lot of people's usecases

[leaden solstice]

Using DI doesn't really add much complexity anyways, if not simplify code spaghetti.

[swift falcon]

Did you manage to continue ? I'm trying to do more or less the same thing

[cold parrot]

Also DI (containers) introduced in a project where most devs don’t ‘get it’ is basically a death sentence for productivity. People will abuse it to recreate the bad patterns that it was supposed to fix.

[latent latch]

I use player singletons when Im lazy and making a one-off game

[cold parrot]

I would encourage any team to figure out patterns that solve their specific workflow issues (from a team perspective) and be very sensitive to the actual dev experience and subtle nudges any such architecture decision produces

usually when cooperating with others in a project many things that make sense solo suddenly become a crippling liability. And there is a desire to find ways to restore that solo dev productivity.

void UpdateColors(Player targetPlayer = null)
{
    if (targetPlayer != null)

i'm making a multiplayer game with photon pun where players select colors in the room, but when i'm updating the color buttons with this function, the buttons which are already claimed flicker (they become interactable and the X text on top of it gets disabled for a split second). how can i fix this? i've tried rewriting the function in many different ways but it didn't help.

[plucky inlet]

totally agree 100%, but couldnt add the emote 😄

[latent latch]

Singletons arent truely static though and have a lot more uses than just being some static accessor to some data. You can always just not flag it as Don't Destroy so when you load the next scene you can grab a whole new (specific) instance instantly from that same accessor

[thin aurora]

Oops, blocked 😄

[latent latch]

And I feel like that's expect because there's no way to get any actual entry point to data when loading a new scene

[plucky inlet]

haha, wonder what I did to that person, cant remember. well, sorry then 😄

[leaden solstice]

That'd be bit of Unity specific issue

[thin aurora]

You know one massive issue with singletons is that you can't depend on eachother. A provider would solve that too singe you grab your instances from a generally available location instead of having the risk that the singleton wasn't initialized yet

The only issue is ensuring the provider exists, which is a lot easier than fiddling with the order of everything else

TBH Unity should have had a Main method

[cold parrot]

The concept of a singleton in unity is so fundamentally misunderstood and abused that it has lost most of its meaning. Most use and understand it as basically a static public variable and don’t get the uniqueness property at all.

[hexed pecan]

Then you end up with ProviderProviders

[thin aurora]

You can just make sure there's a script that is invoked before anything else, which initiates the provider

Which, note, by itself can use the whole singleton pattern. You have to do that anyway in order to access it

[cold parrot]

You should call it a service locator cause that’s what it is.

[thin aurora]

Yep, exactly

[hexed pecan]

I guess this could be used for an entry point
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/RuntimeInitializeOnLoadMethodAttribute.html

[thin aurora]

Yes, this is a very good solution

It's also that if you intend on changing the lifetime of objects, you can specify it in here before the provider has to start providing at all

[leaden solstice]

That is what most of DI libs use

[thin aurora]

.NET APIs also have a period where you can register dependencies before it runs

[cold parrot]

It boggles the mind that a service locator is such a trivially easy improvement over the singleton, yet nobody uses it and continues with the singleton nonsense for silly ‘convenience’ reasons.

[thin aurora]

Yeah, that's generally why I mention them

I'd argue it's even easier

[cold parrot]

Also it’s a very small step from a service locator to DI container if you later decide to go that way

[plucky inlet]

So you would have like a main ServiceLocatorClass that holds reference to all other providers and on the scripts accessing those providers, you now access the servicelocator.provider?

[cold parrot]

Services.Get<IMyService>();

Hey all, could anyone help me figure out why my videoplayer does not have any audio? The video part plays just fine. I have it set up as follows

private VideoPlayer vp;
private AudioSource audioSource;

...

vp.audioOutputMode = VideoAudioOutputMode.AudioSource;
audioSource.volume = 1.0f;
vp.controlledAudioTrackCount = 1;
vp.EnableAudioTrack(0, true);
vp.SetTargetAudioSource(0, audioSource);

vp.Prepare();

yield return new WaitUntil(() => vp.isPrepared);

Debug.Log("Done preparing cutscene video");

vp.Play();
audioSource.Play();

[latent latch]

Yeah GameManager being the only singleton you need is probably the best way around it, but there's one issue with that and you end up with some very large variable accessors ;p

[cold parrot]

No, game manager public singleton is also an anti pattern

there is no need for the systems to know about the manager as a whole

[leaden solstice]

God class

[cold parrot]

systems should only depend on the bits of information that they actually need and that info should be injected

[latent latch]

Seems hard

[cold parrot]

It’s always hard until you realize it’s not

[latent latch]

You expect that GameManager to know the state of the whole game at all times

[cold parrot]

you do the thing constantly, out of necessity, in all your normal code, you just never think about its directionality

[latent latch]

opposed to keeping some independency between the objects. I mean in a perfect project it would make sense but that seems like a lot of extra work

[cold parrot]

Why are you making these assumptions

The game manager is just another system that also only knows the tiny bits that it must control

No system knows everything

the service locator or di container also just knows how to create or where to locate a service/resource but nothing of what it actually is

[leaden solstice]

Generally: you can break down your game into states that defines part of your game and services that uses those states

[cold parrot]

Oh and if you feel this makes it annoying because you can’t just call methods on anything at any time: that’s the whole point.

[steady bobcat]

just use 1 big script for your entire game /s (some guy on twtr did this :|)

[latent latch]

I'd probably have to look into that idea more. Feels like you'd abandon a lot of how Unity even works such as ignoring a lot of the instantiation calls.

[cold parrot]

You can use these principles of separation even in monolithic scripts, it’s not something that relies on language features to be possible 🙃

[steady bobcat]

that is true if you have many classes at play but just 1 "monobehaviour"

i wouldnt do this but i guess its certainly possible

[cold parrot]

Not at all, that is a misunderstanding, if you abandon unity, you’ve gone in the wrong direction

the only situation where you need the service locator is for a component on a dynamically spawned object to find its managing system (usually part of a scene or other persistent context), register with it and receive all the remaining init/dependencies from there

I've actually been refactoring my code as I changed the approach a little bit, would be happy to provide some assistance on what I do have

[covert dust]

Okay, can someone please tell me the current working way of updating the mesh collider mesh at runtime? The project is an URP project in 2021.3.45

Tried a bunch of fixes from forums and none of them work 100% of the time.

[reef garnet]

Unfortunately sidewalks are an unsolved problem

[leaden solstice]

Literally guide for it https://docs.unity3d.com/Manual/prepare-mesh-for-mesh-collider.html

[hexed pecan]

It's doable with some vector maths

How is the road mesh generated in the first place? Sidewalks generation wouldn't be too different from that

[hexed pecan]

What do you mean with updating it? Swapping it out or modifying the mesh?

And what issues did you run into?

[covert dust]

I made procedurally generated terrain divided into 2x2 unit chunks. Each chunk creates a mesh that is used both for rendering and collision. When I use terrain destruction functionality, the rendering of the mesh updates but the collision sometimes doesn't.

[hexed pecan]

How do you modify the meshes, on gpu or cpu

(Also 2x2 is a weird chunk size 🤔 )

Or is that just the size in the world, but resolution is higher

[covert dust]

it's 100% CPU side at the moment

2x2 is the unit size, it's 12x12 vertices

it's a top down game so it doesn't really need more detail

[hexed pecan]

Are you sure you aren't passing invalid mesh data into the meshcollider

[swift falcon]

That's self intersecting polygon with the edges of your mesh, you could try different things to detect it. You could find if n and n+2 (or n, and n+ ... , non consecutives) edges intersects, or calculate winding number of diferents points on the left or right of each edge

[hexed pecan]

That should give some warnings at least

We can't help much without seeing the code or other details tbh

[covert dust]

to give a bit more context, this is called each time a mesh is recalculated:

    private void UpdateMesh()
    {
        if (_mesh == null)
            _mesh = new Mesh();
        _mesh.Clear();

        _mesh.vertices = _vertices;
        _mesh.triangles = _triangles;

        _mesh.RecalculateNormals();
    }

which should make sure the mesh is completely replaced with a new one I imagine? the _mesh variable is then applied to both mesh filter and collider

[covert dust]

majorly doubt it, it's always a flat plane with modified vertex heights, nothing spatially fancy

[hexed pecan]

You might need to notify the physics engine about the mesh/collider changing somehow

@covert dust Try if something like this helps

meshCollider.sharedMesh = null;
meshCollider.sharedMesh = mesh;```

[covert dust]

I did as the first solution I found online

😆

as I said, none of them resulted in anything

some of them even worsened the problem

[hexed pecan]

Wdym "as i said"

How could i know you already tried this

[covert dust]

Said it here, but that's not important, thanks for the suggestion anyways

[hexed pecan]

Well, i didn't read any forum

Just thinking logically

[covert dust]

yeah sorry, that was literally the first google result 😁

[hexed pecan]

When it happens, does the mesh collider seem to use the previous mesh data?

Or does it not work at all

And did you try messing with the cooking options (such as disabling all)

[covert dust]

okay, to make matters funnier, I reverted it to the pre-fix state and tried to reproduce the problem and it's not happening at all

💀

[covert dust]

it uses the previous data

[covert dust]

was planning on getting on that

[hexed pecan]

Wdym pre-fix state, what's different

[covert dust]

                // here it calculates new vertex heights

        UpdateMesh();
        _meshFilter.mesh = _mesh;
        _meshCollider.sharedMesh = _mesh;

[covert dust]

UpdateMesh() being this

[covert dust]

this was the original state before I tried any fixes

okay, it finally broke

took me like 5 minutes of nuking the map as I generate new chunks

And bye

[pulsar plinth]

soooo, a 2d sprite is just a plain rectangular mesh with a texture, right?

[hexed pecan]

Yeah, it's a quad

You can see its triangles if you turn on wireframe mode in scene view

[pulsar plinth]

can I render a single 640x360 rectangular mesh for an entire screen, and draw textures inside it to optimize the game?

[leaden solstice]

Wouldn't just scaling resolution easier

[steady bobcat]

draw calls bad! so i will instead of an mega shader that somehow layers 100+ sprites together! /s

[pulsar plinth]

it's actually worse to do that?

[steady bobcat]

Of course. gpus are able to handle many tris and batching helps combine many meshes to be drawn in 1 draw call

(the message was sarcasm btw)

[pulsar plinth]

ah I see

[pulsar plinth]

yeah I see lol

I'm still learning about meshes and textures
in fact, I'm actually starting to

[leaden solstice]

if (usedColors.Contains(colorButtons.ToList().IndexOf(color))) This is very inefficient

[torn solar]

.Contains() part?

[leaden solstice]

No, you are creating list, then looping over that list to find index

Which you could get it for "free" if you just use for loop

[leaden solstice]

You might want to add video or something to show what you mean by flicker/disabled for a split second

[torn solar]

alright imma record it

[manic ether]

Hello! Need some help reducing the size of my game.

The total user assets size is shown as : 31.7mb
but the total build size gets to 141 mb,
I have set Managed Stripping Level to High.
That has taken down 20 mbs as my build size was originally near 159mbs.
Done all the optimizations to assets as Images/Textures/Models, etc

Don't know what to do more to get the size down to around 50-60 mbs

[leaden solstice]

And is UpdateColors only place you are updating those?

[torn solar]

turns out that's all i needed lol

i feel dumb

i forgot about another function which runs when the player selects a color and i completely forgot about this part

tysm

[manic ether]

? anyone

[vital salmon]

hi hi how heavy is VR with regards to performance? My game renders many materials and gameobjects as well as lights. It probably won't be able to deal with VR

[thin aurora]

Not something suitable for this channel. This is a coding channel.

I have no idea what would be the best so you should probably just ask this in #💻┃unity-talk. People there probably point you to the correct one if needed

[torn solar]

for (int i = 0; i < colorButtons.Length; i++)
{
    if (usedColors.Contains(i))
    {
        colorButtons[i].GetComponent<Button>().interactable = false;
        colorButtons[i].transform.Find("X").gameObject.SetActive(true);
    }
    else
    {
        colorButtons[i].GetComponent<Button>().interactable = true;
        colorButtons[i].transform.Find("X").gameObject.SetActive(false);
    }
}

is this okay?

[leaden solstice]

Yeah, that looks much better.
If you can reduce GetComponent/Find calls then it's even better but it may involve some refactoring.

[thin aurora]

You should never use Find methods. Considering you're on component level already you should be able to just use GetComponent here

Also a styling note, you could simplify your code here because it only differs in the boolean. If you would like an example here I can provide it

I feel like you can make it even simpler considering usedColors appears to be a subset of colorButtons. Is it?

[torn solar]

no, usedColors is a hashset created in the same function

HashSet<int> usedColors = new HashSet<int>();
foreach (Player player in PhotonNetwork.PlayerList)
{
    if (player.CustomProperties.ContainsKey("Color"))
        usedColors.Add((int) player.CustomProperties["Color"]);
}

[thin aurora]

Ah, then let's forget about that part 😄

[torn solar]

i was thinking about creating these 2 variables to replace GetComponent and Find calls

[SerializeField] private Button[] colorButtonComponents;
[SerializeField] private GameObject[] colorClaimedOverlays;

i already had these 2 for the buttons and the colors before

[SerializeField] private GameObject[] colorButtons;
[SerializeField] private Color[] colors;

so would it be efficient to create a struct to combine these 4 variables?

[leaden ice]

There's no need for the GameObject array

Just use the button one

But yeah use a struct

[torn solar]

yeah i think i'll do that since i don't use colorButtons itself right now

[leaden solstice]

Better way is having a component that holds related information for your object, for example ColorSelectionButton, then other components can reference that component.

Then you can properly capsule what you do into methods like colorButtons[i].SetInteractable(!usedColors.Contains(i))

[dusky lake]

the engine itself with all assemblies still needs some space, even if you build an empty project you will have ~100mb

[steady bobcat]

nvm realised now you had this answered elsewhere

[fast dune]

I know that Debug.Log can be quite bad for performance. Would this be a good solution to remove Debug.Log from production builds?

namespace MyGame {

  public class Debug {

    public static void Log(string msg) {
        // we're in a production build
        if (!Application.isEditor && !UnityEngine.Debug.isDebugBuild) {
          return;
        } 

        UnityEngine.Debug.Log(msg);
    }

  }

}

[thin aurora]

I don't see why it would be bad for performance. Where did you find that info?

Generally the logging sink of Unity is always through this, or the ILogger which basically does the same (except keeping gameobject context)

[fast dune]

experience, and e.g: https://discussions.unity.com/t/does-debug-log-effect-performance/525017/2

[steady bobcat]

I do this for editor/debug build only logs:

#if DEBUG
Debug.Log("foo");
#endif

[thin aurora]

Very interesting

[steady bobcat]

logging a lot at runtime isnt good as it does write to various places and generate call stacks

[thin aurora]

You can always make a wrapper method and use the Conditional attribute which targets DEBUG

This way the method will be stripped out in builds, or applications without the DEBUG conditional

I suppose ideally you'd make a general logger that uses Debug.Log as its sink in DEBUG, but a different one in production. I can imagine you'd still want to log warning/error/critical level log message

Serilog works super well for this, and is the most popular approach

[craggy veldt]

Debug.log will do stack tracing and write to a file, it is surely bad

[thin aurora]

[Conditional("DEBUG")]
static void DebugDebugLog(string message)
{
  Debug.Log(message);
}

You get the idea

I'd use Serilog though. You can filter based on classes if done right so you can just turn off everything you don't need

[fast dune]

thanks!

[craggy veldt]

note tho, [Conditional("DEBUG")] will touch the IL land, while #if UNITY_EDITOR or #if DEBUG wont

[thin aurora]

Still better than wrapping every single call in a conditional 😄

Omits the performance issue at least

[fast dune]

will touch the IL land

Why is that bad?

[craggy veldt]

it still exists in the IL on release

not that bad

[thin aurora]

It means that it's not fully stripped. Rather it checks on invoke if the method can be called

Which is a really negligible difference

.NET also has code contracts. I believe this is the real way of doing this. Never used it though.

https://learn.microsoft.com/en-us/dotnet/framework/debug-trace-profile/code-contracts?redirectedfrom=MSDN

Really goes over my head when I read these things

Oh, nevermind. This is for .NET Framework

No idea where I got this idea from then

[thick terrace]

code contracts are like the more powerful version of [NotNull] , [MaybeNullWhen] etc, they're just for verification

[thin aurora]

Been seeing them everywhere. I guess I was looking at really old code then

[thick terrace]

they're useful, you can specify that method doesn't return on some condition for example, which in IDEs like Rider will give you better warnings, like if you have an AssertNotNull method you can tell RIder it'll throw if you pass a null object in, therefore all usages of the object after that don't need a null check

i assume VS can do that too but i'm a Rider for life person lol

[thin aurora]

Note
Code contracts aren't supported in .NET 5+ (including .NET Core versions). Consider using Nullable reference types instead.

I wish I could 😛

[thick terrace]

well they work in Unity 😛

[craggy veldt]

you can alway polyfill them if it's not supported, it's not that hard

[thick terrace]

oh yeah in Unity it's provided by Jetbrains.Annotations

[left void]

My unity is taking too long to load empty scenes in async mode, spending 5 sec or more

[plucky inlet]

So? whats the question, whast the code 😄

[heady iris]

I've noticed that a lot of the time spent on a scene load is actually from unloading another scene

including a big GC pause

[rustic ember]

Physics.Raycast(ray, out RaycastHit _hit, HUDSelectMaxDistance, HUDSelectLayermask))``` I want the Ray, the RaycastHit, and the LayerMask. If I remove the distance parameter, it treats the layermask as maxDistance. Do I just pass in Mathf.Infinity as the maxDistance, or is there a nicer way to do this?

[rigid island]

why not just lookup the signature ?

or just use the named parameters thing to arrainge your own order, you just need the correct amount of params

[thick terrace]

yeah, infinity is the default value

[rustic ember]

Wait what? I can do layerMask = 5, ray = this.ray, etc.?

[rustic ember]

What is a signature?

[rigid island]

layermask : mylayer maxDistance : myDist
etc.

[rigid island]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/methods#method-signatures

[rustic ember]

':'?

[vestal arch]

yes, this isn't python lol

[rigid island]

mhm that lets you place parameters in any order you want, but yeah you still need the same amount

[vestal arch]

if it were = it'd be ambiguous with an assignment

[steady bobcat]

foo(bar: 1)

[rigid island]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/named-and-optional-arguments

[rustic ember]

I guess. I just thought I was setting the variables of the method (idk)

[vestal arch]

well you kinda are, but not through assignment

[rustic ember]

So I still need a maxDistance value?

[rigid island]

yeah for that specific signature yes

each signature has its own order and number of params

[rustic ember]

I'm confused. I'd assume that as long as they had a default value, they'd be optional paramters

[rigid island]

if it has = in the signature, it means you dont have to write anything cause it has default value

[rustic ember]

I see

So since maxDistance has a default value, I don't have to write anything for that paramter?

[rigid island]

if you use a signature with a default value, you don't need to no

default iirc is mathf.inifinity

[rustic ember]

But then how does it know which signature I'm using?

This is really interesting

[rigid island]

your IDE ideally should help you

Raycast has over 16 signatures

[rustic ember]

So in my example: cs Physics.Raycast(ray, out RaycastHit _hit, HUDSelectMaxDistance, HUDSelectLayermask) I don't want the HUDSelectMaxDistance

How do I doi the out thing?

[vestal arch]

they don't overlap; if they did that'd be an error on the declaration

[hexed pecan]

Think you just need to pass in mathf.infinity like you originally said

[rigid island]

Yeah you can just pass that again

[rustic ember]

Okay, but how would it work with this way of doing it?

[rigid island]

wdym how?

[vestal arch]

named parameters just let you pass stuff out of order

[rigid island]

yeah you stil need the same amount , just can be placed in diff order

[vestal arch]

not sure how that relates to passing Mathf.Infinity to one of them

[rustic ember]

But what about the default valuesa then? They don't apply in that case?

[rigid island]

the signature you chosen probably didn't have default value

[rustic ember]

I'd still have to pass a maxDistance?

[rigid island]

the one with the out doesnt have a default value for max distance

so yes

[rustic ember]

It just says in the docs: cs public static bool Raycast(Vector3 origin, Vector3 direction, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

[rigid island]

wrong signature

you're using the one with out

[rustic ember]

I see

[rigid island]

eg

public static bool Raycast(Vector3 origin, Vector3 direction, out RaycastHit hitInfo, float maxDistance, int layerMask, QueryTriggerInteraction queryTriggerInteraction); ```

[rustic ember]

Is there a reason that it doesn't have a default value like the other?

[rigid island]

no idea, thats something some unity dev thought of

just pass Mathf.Infinity same thing

[rustic ember]

Alrighty. Thank you for answering my many questions 😅

[rigid island]

np 🙂

The signature from the source code ```cs
static public bool Raycast(Vector3 origin, Vector3 direction, [DefaultValue("Mathf.Infinity")] float maxDistance, [DefaultValue("DefaultRaycastLayers")] int layerMask, [DefaultValue("QueryTriggerInteraction.UseGlobal")] QueryTriggerInteraction queryTriggerInteraction)

I wonder how defaultvalue attribute works

Some c++ shenanigans i guess

[hexed root]

oh shit didnt see that, thanks

[hexed pecan]

Also... aaaah

static public

Looks so wrong to me, i always do it the other way around

[late lion]

Might just be for documentation generation.

[rigid island]

lol oh wow its reversed

that threw me off for a sec

ohh its actually working.. huh TIL

[late lion]

Shows up here

[rigid island]

writing it flipped feels wrong

why did microsoft allow both 😛

[hexed pecan]

That would make sense

[heady iris]

The other overloads are excluded from the documentation

I dunno why they did it this way instead of just having one definition with default values

Perhaps it's more convenient for other code generation

[karmic stone]

so Axel, Raycast has 16 different methods, all named Raycast. c# knows which method to use based on what type of inputs you give it, what order its in, and how many inputs. For example foo(int num) and foo(string num) are declared in the same class. if you use foo(37) youll get int, and if you use foo("37") youll get the string method. This is called overloading a method, when you create different methods with same name, but different inputs.

Debug.Log is slow in the editor, because it causes the Console window to redraw

in standalone builds, it is hard for it to matter

[compact spire]

If I have a large number of meshes (and colliders) under a single gameobject (which will have some physics applied to). From a performance standpoint does it make sense to merge those meshes together?

The meshes will share some common geometry so I should be able to remove a few faces here and there

[polar marten]

Is it a car?

[polar marten]

It’s empirical. There’s no hard and fast rule. https://assetstore.unity.com/packages/tools/modeling/mesh-combine-studio-2-101956 read the docs for this to understand more

[pulsar plinth]

so I've just used the multiple sprite mode in a sprite to accommodate a sprite sheet
what is the C# class which represents a multiple sprite mode sprite sheet?

the Sprite class only fits a single sprite in it, not a whole sheet

[heady iris]

The importer settings determine how the importer interprets your texture

when you use the "Multiple" mode, it creates more than one Sprite asset

There is no "multiple-sprite" type

[pulsar plinth]

ahhh I see, thank you

[polar marten]

what is your goal

[compact spire]

@polar marten It could be a car, or plane, or boat. Boat I think has the more interesting complications, if using the mesh collider for calculating bouyancy

[polar marten]

you should use a tool to combine the meshes, and read the documentation

it will explain all the limitations / what is required to get a performance boost from mesh combining

physics it's much simpler. the more colliders, and the more faces on those colliders, the more expensive collisions are to calculate.

Does anyone know how to make a very smooth camera in unity

[north hatch]

like this

[steady moat]

Exactly, learn how to do that by following tutorials.

[north hatch]

ok

[pulsar plinth]

actually, when the multiple sprite mode is used it does not split the sprite into multiple different assets
the spritesheet is still a whole image, however I suppose it has the properties to tell a sprite renderer or animation clip what the position of each slice is so it can render the sprite

[leaden solstice]

It does make multiple assets. If you expand the texture asset you will see those subassets.

[heady iris]

The "spritesheet" is just a texture

each Sprite is an asset that tells you:

• which texture to use
• where to look on that texture

[pulsar plinth]

ahhhh, I see

I thought you meant each asset was its own texture

[heady iris]

Ah, no, that does not happen.

[pulsar plinth]

for context, I'm using DrawTexture instead of SpriteRenderer for optimization matters

[polar marten]

use cinemachine

[leaden solstice]

Very suspicious statement you got there

[polar marten]

since you decided to do this, you might as well not import sprites at all

[leaden solstice]

Did you actually profile your game

[polar marten]

i don't think you have to worry about it.

[leaden solstice]

Or you just assume there will be perf issue

[north hatch]

first person

[polar marten]

cinemachine is a very capable camera system, even for first person games

[polar marten]

the previous discussion = the user wants to write his own sprite engine for fun. so it goes

[pulsar plinth]

actually, not really yet
however I already know each entity will render more than a single sprite and thus I don't want to create an additional game object for each sprite needlessly

[polar marten]

i wouldn't worry about it

[leaden solstice]

Care about batching instead of that

[pulsar plinth]

batching?

[polar marten]

it's not really possible to engage since this is all being written from scratch

[leaden solstice]

Reinventing the wheel

I see

[pulsar plinth]

yeah, exactly

[polar marten]

don't stress about it

[leaden solstice]

Your draw call is batched if you use correct atlas setup and material

[polar marten]

i think you'll figure it all out

[pulsar plinth]

however, I'd still like to know what batching is

[pulsar plinth]

but like, batched how?

[leaden solstice]

Look into frame debugger

[pulsar plinth]

what would that do?

does batching allow a sprite renderer to render more than 1 sprite at each frame?

[leaden solstice]

No? It means multiple sprite renderers' draw call can be combined to batched draw call

[pulsar plinth]

I see

[rustic ember]

Hi! I have a Vector3 that I need to rotate 90 degrees around another Vector3. How can I do this? I know I can multiply a Quaternion by a Vector3 to rotate the Vector3, but I have no idea how to do it

[leaden solstice]

"Rotate around" as in Quaternion.AngleAxis?

Or rotate around as in the other vector as origin

[rustic ember]

Possibly, let me take a look

[rustic ember]

Yep, that's solid! Thank you 😅

Quaternion.AngleAxis(90, transform.forward) * vectorToRotate``` So this would work right?

I want to rotate the vectorToRotate 90 degrees around the objects forward axis

[leaden solstice]

If vectorToRotate is relative to the object then sure

[rustic ember]

Perfect. I figure I can just add vectorToRotate and transform.position after?

[leaden solstice]

Yeah

[rustic ember]

Thank you so much 🙏

[wintry crescent]

can I force passing a struct as a reference into an object type field?

[latent latch]

ref

[wintry crescent]

can't be used with the "this" keyword though

[vestal arch]

wouldn't you have to have ref on the other end, on the parameter?

or the struct, i forget

[wintry crescent]

that's an external tool sadly, I'd rather avoid modifying its code

[wintry crescent]

I can modify the struct though, how?

[latent latch]

what's the error

[leaden solstice]

What are you trying to do

If you want to cast struct to object, you have to box

[latent latch]

oh right you've no typing on that

[wintry crescent]

I have a dependency injection tool that is meant to use classes, but works with structs most of the time
unfortunately, to inject an already created object (rather than creating a new one) I have to pass in the object as a reference, since I'm not getting it back (result type void). It's meant to be a class, so it's not much of an issue... except I want it with a struct

[leaden solstice]

Do you have problem with just boxing it?

[wintry crescent]

boxing it how?

[leaden solstice]

Just call it

Oh you mean you are injecting into struct?

[wintry crescent]

not sure what you mean

yea

[leaden solstice]

That's pretty much not possible area unless the your DI container API supports it

[wintry crescent]

It works, when I'm creating a new object through the api, since the injected object is returned

that's actually a big reason we moved to zenject in the first place

the issue is that it doesn't get returned if I'm trying to inject an already-existing object

[leaden solstice]

I mean populating to exiting struct

Actually you can.. eh

object copy = this;
Inject(copy);
this = (MyStruct)copy;

Could try something like this

[latent latch]

What if you did like some generic class wrapper and just passed the struct in

[wintry crescent]

uhoh that looks not good but I could try...

[latent latch]

I mean I guess that's technically boxing it too

[wintry crescent]

can't wrap it, because then it won't get injected, the wrap will get injected instead

and the objects contained within the wrap won't get injected

which is rather sad but adding that functionality to zenject is way above my paygrade lmao

[leaden solstice]

Zenject is not really my favorite

Bit overcomplicated

[wintry crescent]

I have used a homegrown solution before, but that was too simple and too costly to expand

we had to rip it out and move to zenject because it was just too much work to maintain our own

ok, it was relatively advanced, but it had a million problems and zenject, most of the time, just works

zenject is a bit complex yes but also very powerful when you figure it out

[cosmic fjord]

hello everyone
how to make the parameter on my method become dynamic?

so it send the info of the clicked button

[leaden solstice]

Making it too powerful often ends up weird pattern IMO

[wintry crescent]

wdym?

[leaden solstice]

I mean it's like C++ ig, it lets you do about anything

So it is kinda easy to mess up if you code without caution

[wintry crescent]

I worked in C++ a while, I really wouldn't make that comparison XD

seriously, I have not had problems with it at all

[leaden solstice]

What do you mean become dynamic

[cosmic fjord]

i made a parameter on my method of type " button"
when the player click one of these buttons i want to know the button clicked become the one in the parameter

sorry i mean i want the clicked button as the parameter button

never mind i did it the hard way ( it is not hard but i want to know the easy way for my info)

[runic island]

I'm stupid or this is far more complicated than I gave it credit for. (Or both!)

I'm trying to get my AI to simply walk around a wall, stop within it's attack range, face the target (core) and then shoot. It sounds simple, no?
For some reason it walks around the wall, runs all the way through it's target, then faces the target (core) then shoots.

I'm so lost, I can't find a reason why it's acting like this although hopefully it's obvious to someone else. I'm on hour 3 trying various fixes, reading the navMesh API and I am just at a loss.

Help appreciated, thanks in advance.

[runic island]

Note that my enemy (The AI this is attached to) is set as a kinematic body.

[leaden solstice]

Have you attached debugger and see if the code working as intended?

[runic island]

I've littered the code with debug.log statements if that's what you mean. It doesn't enter the else if() portion of the update function until it fully runs into the core for some reason.

My thought process is since this if statement is asked every frame it should update pretty much instantly when it's within the attackRange and stop moving via the second part of the code. The issue is that it's just not getting into that code until it's well past that point.

If debugger is a unity tool, I'm unfamiliar with it.

[leaden solstice]

https://docs.unity3d.com/6000.0/Documentation/Manual/managed-code-debugging.html

You'd want to get familiar with it, it's your best friend

[runic island]

This sounds wonderful. Where has this been my whole life?

Also I just commented out after else on line 50. That seems to have worked... I just overcomplicated the function it seems. ;-; I only thought to try that because of my reply to you so thank you again.

[compact spire]

To create trasnparent bullet holes in a mesh, would some sort of texture mask or shader be the best option?

modifying actual geometry seems.. expensive

[wicked scroll]

Yep, usually bullet holes are just decals of some kind. If you need them to be truly transparent, you could write a shader that samples from a 'damaged' texture and clips the bullet hole areas

[polar marten]

what do you mean, transparent? are you trying to say, conventional bullet holes, like in every other game? or are you trying to say, the hole goes through the mesh, and now you can see through it?

[polar marten]

you have to declare a new class and set the struct to be a field on it, then inject that.

[wintry crescent]

that won't work

[polar marten]

i guess, why is it a struct at all if you need to inject it? just make it a class

struct --> class

[wintry crescent]

yeah I ended up doing that, but it doesn't really fit for it to be a class

but whatever

[compact spire]

@polar marten Yeah I want holes in my craft. This is in combination with the combined meshes from earlier. Goal is to build something out of some hull bits, merge such said thing into a mesh, put things into that mesh, then figure out some ways to represent an interesting damage state. Possibly with a combination of texture level stuff and if enough damage, maybe have things break in half using some mesh deformation....

It's.. a lot

[polar marten]

what is the look of the game you want to make

is the purpose of the game to have a destructible spaceship?

is that the game?

you might like mudbun https://assetstore.unity.com/packages/tools/particles-effects/mudbun-volumetric-vfx-modeling-177891?srsltid=AfmBOorU4vX8E6Jf8ROZ1dH3D6tgipPavohxfdWsGM-g4DyTnuy7DNcL @compact spire

there's stuff that's more mechanical and sharper. you are looking for CSG assets. there aren't many though

you will also need a package called "vhacd" to create rigidbodies "with holes" (i.e. multiple rigidbodies of the correct mass)

[compact spire]

@polar marten More like from the depths.

Build all manner of craft, have them fight

[polar marten]

really depends on what you find interesting

take a look at mudbun 🙂

[compact spire]

Well FtD ships are built out of a thousands of simple shapes, and destruction of the shape shows the damage. Elegant, but I'm going with scaleable shapes instead

That have a volume that you put things in

volumetric vfx... hmm

that seems like a completely different kind of direction

[cold parrot]

When you do something new, you have to consider why nobody else has tried the idea so far. There may be reasons why it can't work in terms of complexity, design or effort. Often when something new comes about, its design, workflow and technical implementation are very dependent on each other and it is very unlikely that it can be achieved with off-the-shelf tools.

[compact spire]

@cold parrot That is fair, I feel that it's doable, it just depends on how many compromises I'm willing to make on my idea.

I'm just prototyping right now

I prototyped the building system as far as I need to, to get a feel how it's going t go

now I'm looking into performance feasibility for the physics and other interactions

[cold parrot]

what is the fundamental fun part of the game?

[compact spire]

Building your fleet of craft and then having it fight.

trying to scratch the same itch as From the Depths, Avorion, Stormworks ect

[cold parrot]

so "assemble stuff and watch it explode"?

[compact spire]

There is more beyond that, but that's the root of it

[cold parrot]

and how are you innovating and enhancing that?

[compact spire]

Those mechanics specifically? Different building system

[cold parrot]

i mean, why is your system more effective at scratching the itch?

[compact spire]

Less complex/ more efficient building system. Easier to build what you want. More of a focus on something a bit more rounded than FtD/Stormworks

[cold parrot]

will it also be prettier?

[compact spire]

I don't know. It should end up looking better than FtD

[cold parrot]

do you have maybe also have a stronger narrative or thematic hook?

[compact spire]

Stormworks has a clean aesthetic that I'm not really going for

narrative and theme are outside of what I'm prototyping

[wicked scroll]

so are there predefined modules that you kind of assumble into a big warship?

[compact spire]

Sort of

Imagine a lot of basic shapes, but you can scale them to make a hull

the hull has volume that you fill with things

[wicked scroll]

I'm not sure I'd bother with stuff at decal scale then. I think you'd want to predefine some 'fracture lines' in each shape and then decide how to break them based on incoming damage

[compact spire]

I'm playing around with mesh skewing to get even more customization out of the shapes

[cold parrot]

Well, i find this kind of game very interesting to make, but having made such a thing recently (a building game), its just a huge mountain of work. I would aim to keep stuff as simple as possible and search for a really strong twist on the basic idea that does not require you to have 1000s of build options, but as you said, thats basically what your innvation is, so it think thats a good one.

[wicked scroll]

whenever I try to design a ship-based combat game I get stuck on that the fantasy is really strong, but in practice, ship combat is actually very slow and binary in a way that makes it not very fun to watch and only marginally fun to participate in.

[cold parrot]

i would expect that if you make more free-form and rounded, non-grid, or not hotspot-snapped shapes you will explode your complexity

[compact spire]

@wicked scroll have you played From teh Depths?
