What is AdminUser?

fresh salmon Mar 18, 2022, 10:16 AM

A type that implements IEntity probably, you can extend the pattern matching of your if statement to do the cast for you

if (xUser is AdminUser asAdmin) {
  // 'asAdmin': variable 'xUser' casted for you
}

im struggling with a concept ive been trying to code for a while, if someone could help me figure out how to go about what im trying i would appreciate the help

In this game im trying to program, a character can play 3 cards onto a field, with 1 being a primary action and 2 being secondary. Im trying to make these actions configurable scriptableobjects but im struggling to figure out how to go about making them. (Here is a sketch of how it sorta works, with blue numbers to show the order of the types of cards that should activate)

#

the numbers in front of the letters reperesent turn order, the letters just represent different characters

#

Skills are individual, and go last. Modifiers should go first to modify the primary action, in this case a weapon, and THEN the primary action occurs

remote pumice Mar 18, 2022, 2:18 PM

#

Sounds interesting, what exactly are you struggling with? Basically, i think you'd have a List of these Actions and evaluate from Last to First, and the Current Evaluation affects the Evaluation of the next one?

hushed sparrow Mar 18, 2022, 2:18 PM

#

just trying to figure out how to make the system work, i want to see how other people would try going about it

#

im struggling with setting up ScriptableObjects for the cards

#

since many cards would have different abilities/modifiers and all that

#

also cards affect lanes/targets dependant on which lane theyre in and i feel like ive gotten myself into a complicated mess :p

remote pumice Mar 18, 2022, 2:21 PM

#

Mhmm I see, you could, for example, make Abilities and Modifiers as standalone Scriptable Objects as well

#

For affected Lanes and Targets, you >could< use Enums

#

enum AffectedLaneType { Left, Right, Center }
enum AffectedTargetType { PrimaryAction, SecondaryAction, // some more concrete ones }

#

Just as an example.
I've got a Gwent-Like (The Witcher 3) Game Vision from your explanation

hushed sparrow Mar 18, 2022, 2:26 PM

#

ill see what i can do

#

im also not sure how to handle the targeting, since this is how i have the lanes set up but it could be subject to change if need be

#

and this is how ive got my current Card class set up

remote pumice Mar 18, 2022, 3:27 PM

#

You could for example substitute the abstract onPlay() and have another class

PSEUDO
class CardBehaviour : ScriptableObject void Execute(Card card)
and your Card would have a list of Behaviours assignable in the Inspector

You'd still need to create concrete Implementations of CardBehaviour, but it's eleminating the need of subclassing Card

remote pumice Mar 18, 2022, 3:29 PM

#

hushed sparrow im also not sure how to handle the targeting, since this is how i have the lanes...

Targeting, IMO, should target a Lane in the first step, not it's Contents
Validating that the contents are what you expect for your Cards Action would be following this

Eventually, each Lane could have a visual representation with a Collider, hence allowing targeting via, for example, Raycast

hushed sparrow Mar 18, 2022, 3:29 PM

#

i actually did a little work, let me show you what i came up with for targeting

#

its basic and a little messy, but it works for now

remote pumice Mar 18, 2022, 3:30 PM

#

Sure! But Images and stuff may take a while to load, my wifi is almost non-existent

hushed sparrow Mar 18, 2022, 3:30 PM

#

i see

#

should i just copy and paste the bits of code then?

remote pumice Mar 18, 2022, 3:31 PM

#

It's fine! It did load already, since it's very small

hushed sparrow Mar 18, 2022, 3:31 PM

#

i see

remote pumice Mar 18, 2022, 3:32 PM

#

From that snippet, what is not obvious to me is, do the Players manually select their Target or is it abstracted away into the Cards Actions?

hushed sparrow Mar 18, 2022, 3:34 PM

#

the target is selected dependant on which lane the card is played in

#

since characters are also in said lanes

frank peak Mar 18, 2022, 6:38 PM

word, thats good to hear

#

something simple like OnBecameInvisible didn't work, im guessing due to the staggered z levels of the tilemaps

#

#

well you can only see one plane here

#

but it extends back

#

maybe thats not the issue idk

#

(screenshot taken before i wrote the script)

green river Mar 18, 2022, 6:47 PM

#

regarding the flickering... here's what we are seeing on many Windows machines. We did some digging and it looks like a lot of the issue is occasionally the game is drawing things from the wrong atlas, particularly in the UI canvas elements, for a frame

#

doesn't happen for any of our mac users.. so there was a hunch it might be to do with multithreaded rendering on dxd11

#

(metal doesn't have issues)

#

QualitySettings.maxQueuedFrames = 1; did not work sadly to resolve it.

#

-force-gfx-direct does resolve the issue but that would require players to add CLI args

#

we tried doing opengl-core, dxd12 builds to no avail

#

here's a still of some of the sprites drawing from the wrong atlas for a frame

#

whereas... that section should look like this

#

so... it SEEMS like due to MT rendering... it's just the framerate dips and 2 threads are maybe changing the loaded ui atlas at the same time... and 1 thread just draws from the wrong atlas

#

i know i need to do a performance pass, but even still.. this will just happen on lower spec machines.

sage radish Mar 18, 2022, 6:57 PM

#

green river `-force-gfx-direct` does resolve the issue but that would require players to add...

You should be able to turn off multithreaded rendering in Project Settings.

green river Mar 18, 2022, 6:58 PM

#

as far as i can tell... and this is agood Q for the group... unity determines whether to use MT rendering by a variety of factors

#

lemme screenshot project settings rq

#

afaik.. it's supposed to be in this section

#

#

what we'd done to test on various APIs for windows was just go in here and

#

#

just sort of swap out what's here

#

we were hoping like... well maybe OpenGL works better than DXD11

#

if there's some checkbox hiding somewhere, i'll buy someone a beer.

although, bribery may be against ToS so...

.. like, is it after updates, is it only on the main thread,.. depends, Task.Run will run in separate thread. Also, async doesn't mean it's multithreaded

#

Save the hassle, and use UniTask instead https://github.com/Cysharp/UniTask

#

You can comfortably switching between Unity's main-thread and threadpool very comfortably

to switch to threadpool with UniTask you just need to await UniTask.SwitchToThreadPool();

Just like async in general, you'd need to manage the cancelation tokens on your own, or by using MonoBehaviours built-in (I think there's one to handle this automatically)

#

Hey I wanted to learn more about vertices by testing out different shapes

maiden turtle Mar 19, 2022, 11:30 AM

#

Load a prefab into memory (LoadAssetAsync or whatnot, via addressables). This step is not a problem.
Instantiate the prefab.
Call all initialization hooks (Awake, OnEnable, Start).
Prevent any Updates from being called.
Initialize the objects externally (I need to control the order more accurately, plus I need to propagate so info from other systems).
Enable Update's

#

So

But I don't udnerstand why this isn't becoming a Square?

The external initialization needs to happen after the internal one happens

What you're seeing is known as backface culling

#

Unity uses clockwise culling order

#

So you want your triangles to go clockwise

median cosmos Mar 19, 2022, 11:32 AM

well it's going from left top back to right

maiden turtle Mar 19, 2022, 11:32 AM

Did you generate the mesh manually?

so it's kinda clockwise

median cosmos Mar 19, 2022, 11:33 AM

it's in Update()

median cosmos Mar 19, 2022, 11:34 AM

you only have one triangle defined

the first triangle should be the first 3 vertices

yes

maiden turtle Mar 19, 2022, 11:38 AM

#

if you do 1, 2, 3 it would go counterclockwise

novel wing Mar 19, 2022, 11:38 AM

#

If you specify a triangle as vertices in a clockwise order, then the triangle will be facing the screen

#

I.E the normal is "forward" of clockwise (if that makes any sense)

maiden turtle if you do 1, 2, 3 it would go counterclockwise

not 1, 3, 2?

top right, bottom, left

so clockwise?

maiden turtle Mar 19, 2022, 11:39 AM

#

it should be clockwise, yes

#

otherwise you'd see the face from the back instead

median cosmos Mar 19, 2022, 11:39 AM

but why is 1, 2, 3 clockwise?

maiden turtle Mar 19, 2022, 11:39 AM

Instantiating a gameobject does not run its Awake immediately, right? It waits until the next frame

It's immediate if it's enabled

maiden turtle Mar 19, 2022, 11:44 AM

I still don't quite get why mine isn't clockwise

#

maiden turtle Mar 19, 2022, 11:45 AM

median cosmos I still don't quite get why mine isn't clockwise

Because you only have one triangle

#

You only put 3 indices into there

median cosmos Mar 19, 2022, 11:45 AM

#

ohh wait a sec

maiden turtle Mar 19, 2022, 11:45 AM

#

While it should be 3 per triangle

#

so 6 in total

median cosmos Mar 19, 2022, 11:47 AM

#

median cosmos

so when the vectors.Count /3 * 3 is becoming 3, it means it hast only one triangle?

novel wing Mar 19, 2022, 11:47 AM

#

maiden turtle aah, ok, then disabling it after instantiating it should do what I want

? It's immediate, if it's instantiated and it's enabled as a prefab, then Awake will instantly run before your code continues

maiden turtle Mar 19, 2022, 11:48 AM

#

Yes, that's fine

novel wing Mar 19, 2022, 11:48 AM

#

You can instantiate disabled prefabs, then it will do nothing until enabled

#

Ah okay

maiden turtle Mar 19, 2022, 11:48 AM

#

I don't want any Updates to run

#

Awakes running is something I actually want

novel wing Mar 19, 2022, 11:49 AM

#

Yeah basically this is the order:

Instantiate()
-> Awake
-> your code continues
-> (next frame) Start is called if the object is enabled

maiden turtle Mar 19, 2022, 11:50 AM

Oh so start is not affected, hmm

I guess that's still fine tho

    new Vector3(0.5f, 0.5f, 0)
};
mesh.vertices = vertices;

var tris = new[]
{
    // lower left triangle
    0, 2, 1,
    // upper right triangle
    2, 3, 1
};
mesh.triangles = tris;

median cosmos Mar 19, 2022, 11:54 AM

but it can't be higher than the vertices number

exactly

but then I can only have 3 6 triangles?

maiden turtle Mar 19, 2022, 11:55 AM

#

median cosmos so if I want a full "cube" I want 8 vertices right?

you'll probably want do double up some vertices

#

because otherwise the normals will be wrong

novel wing Mar 19, 2022, 11:56 AM

and you will need 6(faces) * 2(triangles) * 3(indices per triangle) indices

median cosmos Mar 19, 2022, 11:56 AM

what are indices anyway?

novel wing Mar 19, 2022, 11:56 AM

it's just an int array saying which vertex makes a triangle

it's always a multiple of 3 as all triangles need 3 vertices

why is the square rendered there?

#

how do I make the collider adapt to the mesh?

why is it drawn like this?

I can see the other triangles if I go to the other side

novel plinth Mar 19, 2022, 12:23 PM

#

flipped normals?

median cosmos Mar 19, 2022, 12:23 PM

that means they are facing each other's opposite direction

#

what do you mean by that?

#

this is only for all except the top and bottom

#

?

novel wing Mar 19, 2022, 12:37 PM

#

median cosmos why is it drawn like this?

This is the same issue as you had before, only on another axis.

#

You're giving the indices in wrong order, or not at all

median cosmos Mar 19, 2022, 12:38 PM

#

novel wing Mar 19, 2022, 12:39 PM

#

Why do you have 6 vertices for one side?

#

You only need 4

#

I think you've confused some terminology somewhere or you're missing something

#

you only need 4 vertices (corners) for a side

#

then you need an array (indices) that says which index in the vertex array makes a triangle

#

the indice array needs to be 6 points, because one side is 2 triangles

#

So if you have 4 vertices where 0 = top left, 1 = top right, 2 = bottom right, 3 = bottom left

var vertices = new []
{
    [0] = new Vector3(0, 0, 0),
    [1] = new Vector3(1, 0, 0),
    [2] = new Vector3(1, -1, 0),
    [3] = new Vector3(0, -1, 0),
}```

#

then to make 2 triangles you make a indices array and construct it as follows:

var indices = new[]
{
  0, 1, 3,     1, 2, 3
}```

#

note that it's not actually pairs, I just wrote my text to indicate that a triangle is made up of 3 points each.

median cosmos Mar 19, 2022, 12:55 PM

#

ohhh

novel wing Mar 19, 2022, 12:56 PM

#

For even more clarity, the indices array is just a reference to which vertex it will use:

median cosmos Mar 19, 2022, 12:58 PM

#

so the vertices are for the hole cube, not for every side?

#

no wait

#

for every side right?

novel wing Mar 19, 2022, 12:58 PM

#

yes the vertices is your entire mesh, in this case the entire cube

#

defined as points

median cosmos Mar 19, 2022, 12:59 PM

#

but a cube has 8 vertices

orchid marsh Mar 19, 2022, 12:59 PM

#

Note that the above suggestion is simply for reducing memory foot print. The issue with face culling is due to incorrect normals.

#

ie you're drawing the vertices in the wrong order.

novel wing Mar 19, 2022, 12:59 PM

#

A cube is 8 vertices, BUT having 8 means it will appear smooth, so in this case you want 24 instead:

#

So basically whenever a triangle is using a vertex that another triangle is using (sharing it) the normal will be averages across the triangles normal direction, causing it to look smooth.

median cosmos Mar 19, 2022, 1:02 PM

#

and the indices are for each side?

#

or for the whole mesh, too?

novel wing Mar 19, 2022, 1:03 PM

#

the whole mesh

#

so if you have 24 vertices some of the indices will need to refer to vertex 22, 23, 24 etc

median cosmos Mar 19, 2022, 1:04 PM

#

oh wait

#

so the indices are basically the sides?

#

I'm kinda confused

novel wing Mar 19, 2022, 1:05 PM

#

indices are simply which vertex to use for drawing a triangle

#

3 indices make a triangle

orchid marsh Mar 19, 2022, 1:06 PM

#

median cosmos why is it drawn like this?

It is important to give this order in clockwise direction. Because most of the default shaders render only one side of the mesh. Drawing it anticlockwise would mean, the object is rendered from the other side.

#

Which would induce back face culling - what you're seeing.

Yes definitely, but it stems from having 6 vertices per face

novel wing Mar 19, 2022, 1:10 PM

#

median cosmos so what do I need to write into each draw() function (each side)?

Start by making sure on side works fine using 4 vertices and 6 indices

#

then it's just a matter of repeating it to the other sides

median cosmos Mar 19, 2022, 1:10 PM

#

but what should I do with the indices exactly?

#

like programmatically?

novel wing Mar 19, 2022, 1:11 PM

#

Well it's up to you how you want to solve it, you could manually enter the numbers like I showed in my example (way above) or you could use some algorithm like AntonC showed as well

#

Just make sure that one side is exactly 4 vertices and 6 indices

#

Then you repeat that process for all the sides of your cube, and you end up with a cube that is 24 vertices and 36 indices. 36 indices being 12 triangles since every 3 pair of indices is 1 triangle.

#

If at that point you have triangles "missing", check if they're drawn inside of the cube, if that's the case it's because you didnt specify the indices in the correct clockwise order, like Dalphat talked about

median cosmos Mar 19, 2022, 1:30 PM

#

got it

#

finished with that soon

#

alright now it looks like this

novel wing Mar 19, 2022, 1:33 PM

If you move the camera inside of the cube, can you see the missing faces then?

Hello i have the following problem: i want to make 1000+ scriptableobjects, objects or what is the best to store/handle such amount of different items , where the player can choose from. What is the best way to store them? It is the best way to create 1000+ scriptable Objects and drag them to a List<Item> in a gameobject or what is the way to go, dealing with a large amount of different objects, which will be used dynamically? (like here in the crafting-video (in the pinned time-stamp), he adds for each item a scriptable ojbect in its folder and add it manually in the editor to the list: https://www.youtube.com/watch?v=E91NYvDqsy8&t=1045s)
i wonder how a game like Hearthstone handles their 4.000+ Cards? do they really have long list of Scriptable-Ojbects and add each card in the editor? do they have a long config-file with every card? How do you handle such a big amount of data?

Each game will architecture data loading differently. I bet HearthStone used an external database and tools to build all this data yeah.

still sigil Gotta ask this but if you make such a big game can it literally crash unity?

There are a lot of things that can crash a piece of software. But bigness is a very vague, pretty much meaningless term.

#

You can certainly create a game that exhausts all of the system's memory and that can crash the process, yes.

#

but that can be done simply with a few lines of code, it doesn't necessarily mean the game is "big" in any human sense

example: if you try to manually use Toggle.isOn in the toggle OnClick() method and turn it on when the toggle is clicked (instead of using toggle groups lol), it will cause a stack overflow error and crash unity

i saw the scriptableobject asset "channel" pattern being used in some unity youtube tutorials, i was wondering if i'm missing something or if just making a static class would basically be better? like the pattern seems to be just the scriptableobject holding events and being the thing passed around into inspectors so components can either subscribe to or fire the events

#

assuming i don't use UnityAction and UnityEvent - or is there a reason to prefer those? being able to serialize them in the inspector is handy but i wasn't a fan of the GC and other people seem down on them too

novel wing Mar 21, 2022, 10:41 AM

#

The pattern is specifically to make designer work easy. For instance a level designer can easily hook up events and have stuff happen as wanted without writing a single line of code. For example a box trigger causing the player to take damage.
Sure you can write it in code, and it will be more performant. But then you also have to write it in code

gilded wing Mar 21, 2022, 10:42 AM

#

ah good point, yeah that's moot for me in my single person hobbyist operation

novel wing Mar 21, 2022, 10:43 AM

#

Then it's completely up to you how you want to work with it. But the general rule of thumb is that you make performant tools that allows a designer to rapidly iterate. In iteration speed is more important than pure performance.

#

Something that would affect you though is that the ScriptableObject pattern will automatically track scene dependencies (to some extent), where as manual implementation in C# event you'd have to handle that as well, to avoid references disappearing when loading/unloading scenes

gilded wing Mar 21, 2022, 10:50 AM

#

my understanding is there wouldn't an issue with scene transitions with a static class with static events that the monobehaviours subscribe/unsubscribe to on their unity enable/disable, like if an unity object is going away for unity reasons it's always going to call its OnDisable and then the static object will know - or is there something i'm missing

Theoretically, it should be heavier, since each object contains additional data and components, like the transform, that a 3d array of values doesn't. Now for how much of an impact it has, you'll have to test it. Probably not much, but there would be different numbers on different platforms.

languid isle Mar 21, 2022, 12:18 PM

#

untold moth Theoretically, it should be heavier, since each object contains additional data ...

thank you, that's what I was wondering.

I am just not familiar with how Unity handles 3d objects vs how it handles arrays in memory I know that an array has to be processed during every update cycle. If 3d objects have to be processed on that same level too then it would be heavier 😐

#

which means no matter what i'm pushing how much upper memory is being sucked up with my board game. Not sure how to optimize those values in the array to reduce the processor load.

#

It might cause really nasty lag no matter what 😦

#

each segment on the board (it's a 17x17 board) has 7 values that need to be recorded

Wdym by "array has to be processed on every update"? Where did you hear that? An array defined by you only gets processed whenever you process it.

languid isle Mar 21, 2022, 12:20 PM

#

😮 so it is different in C# than gamemaker?!

#

oh

#

in gamemaker a 3d arraylist is processed every step because it's retained in upper memory

fresh salmon Mar 21, 2022, 12:21 PM

#

Not in C#, arrays are stored in the memory once, and your variables point to that array in the memory

#

So you could make a Tile[,] where Tile is a custom class/struct containing your 7 values

untold moth Mar 21, 2022, 12:22 PM

#

I've no clue about gamemaker, but it sounds wild that something would be processed every frame just because it exists.

#

I'm also not sure what the upper memory refers to. In C# you have the stack and the heap memory, but it doesn't make things access/process it for no reason.

languid isle Mar 21, 2022, 12:33 PM

a c# class object does not have transform that would only apply to a gameobject. and between saving a c# class object with 3 values, or a 3 dimensional array, in another array, this should be pretty similar, so they should benchmark it.

Yeah, but you don't have an empty array in this scenario. You have an array of 300 value types vs array of 300 reference types. Meaning 300 more bytes(assuming that's a correct number). Sure, that's not a lot, and probably shouldn't be taken into account, just saying.

Is there a way to make it so that you have a static script which captures any kind of errors from any kind of script and then creates one of those error dialogue boxes that displays the error as well as the source of the error during a build? I know how to create a error dialogue box but im not sure how to capture a error from other scripts and methods. Could be useful in case someone creates a weird bug of some sort and i need to display a crash message that safely quits the game. I know one game that prints out a lot of warning dialogue boxes in case you mod it but you mod it in the wrong way and i doubt they coded every dialogue box message in every possible script.

basically an universal try catch-ish function? hope this makes sense

does anyone have some good references on optimizing procedural mesh tile map stuff?
at the moment i'm removing and generating the whole visible map at certain intervals (player moving to new tile or depending on size, group of several tiles) which is obviously not ideal since it should only need to create/remove new rows/columns as the player moves
https://i.imgur.com/fVPn1PY.png
the colliders for walls (MapU Walls in profiler) should be the easy part, but i'm not sure how to go about that in terms of generating the mesh (MapU Mesh in profiler) - currently it's one big mesh in one game object; maybe i need to split it into multiple object chunks, so i can create/remove those as row and column groups as needed?
or maybe there are other approaches i can try to reduce these spikes

The image you have looks like the mesh is mostly on screen, I assume it gets bigger than that?

sinful pecan Mar 21, 2022, 2:37 PM

#

yes, i'm doing some basic/scuffed culling when the player is still smaller
for context; you start small and tiles are big, as you grow you see more tiles, eventually i'll have to essentially change the resolution because too many tiny tiles on screen won't be viable, but first i want to optimize the one-map-layer approach

kindred tusk Mar 21, 2022, 2:38 PM

#

Is it just the "recalculate normals" call that is expensive?

sinful pecan Mar 21, 2022, 2:39 PM

#

not just that but it's a big chunk

kindred tusk Mar 21, 2022, 2:40 PM

#

Well one thing that sticks out is that it seems that you have too many vertices

#

Are these black pixels all edges?

sinful pecan Mar 21, 2022, 2:41 PM

#

yeah, i probably want to reduce geometry the more further out it is as well
those currently don't seem important but that's because i have randomization for a more natural look turned off

kindred tusk Mar 21, 2022, 2:41 PM

#

Probably won't solve your whole problem, but if you can simplify the flat areas it should help ease the problem

sinful pecan Mar 21, 2022, 2:42 PM

#

the main problem is definitely that it redraws the whole thing instead of just what's "needed", the geometry is still relatively low-poly

kindred tusk Mar 21, 2022, 2:42 PM

#

Other than that splitting it into chunks like you said should help ease frame delay.

sinful pecan Mar 21, 2022, 2:42 PM

#

i'll make a quick vid with randomization on, that should make it more clear

kindred tusk Mar 21, 2022, 2:44 PM

#

I think you were right the first time, the solution is likely chunking based on what's on or nearby the screen.

sinful pecan Mar 21, 2022, 2:46 PM

#

yeah i'll probably try that first and see if i can squeeze the load down enough

kindred tusk Mar 21, 2022, 2:47 PM

kindred tusk Mar 21, 2022, 2:48 PM

#

If you can write code to just generate some rectangle of coordinates then you can load meshes in as required and just place them on the edges

#

Looks like you already have that.

sinful pecan Mar 21, 2022, 2:48 PM

for some reason these two lines are super expensive as well

Vector3[] verts = new Vector3[SW.TILE_VERTICES * totalTiles];
Vector2[] uv = new Vector2[SW.TILE_VERTICES * totalTiles];

kindred tusk Mar 21, 2022, 2:48 PM

#

sinful pecan for some reason these two lines are super expensive as well ```csharp Vector3[] ...

Hm. Just allocating the arrays?

sinful pecan Mar 21, 2022, 2:48 PM

#

let me make sure that's what it is, but i think so

kindred tusk Mar 21, 2022, 2:49 PM

#

Hm, this is annoying. It seems you can't provide a vertex count

sinful pecan Mar 21, 2022, 2:49 PM

#

to be fair it's 108 verts per tile, so it would be allocating quite a bit of memory

kindred tusk Mar 21, 2022, 2:49 PM

#

oh wiat!

#

https://docs.unity3d.com/ScriptReference/Mesh.SetVertices.html

#

Here we go

#

Try this

sinful pecan Mar 21, 2022, 2:49 PM

#

hah maybe i should cache the entire map as vertex/uv data

kindred tusk Mar 21, 2022, 2:49 PM

#

Allocate a huge array up front

#

And store it as a static

#

static Vector3 _vertices = new Vector3[SW.TILE_VERTICES * MaxTileCount];

Mesh Generate(...) {
  var mesh = new Mesh();
  var count = width * height;
  if (count > MaxTileCount) {
    throw new InvalidOperationException($"{count} > {MaxTileCount}");
  }
  for (var i = 0; i < count; i++) {
    _vertices[i] = ...
  }
  mesh.SetVerticles(_vertices, 0, count);

#

This way you don't need to allocate a new array each time

sinful pecan Mar 21, 2022, 2:52 PM

#

oh let me try that, thanks

kindred tusk Mar 21, 2022, 2:53 PM

#

There's also this: https://docs.unity3d.com/ScriptReference/Mesh.SetIndices.html

#

Oh, you can even use a List if you want to make it flexible enough to render an infinite size, just beware that copying Vector3s from a list is slower than an array.

sinful pecan Mar 21, 2022, 2:54 PM

#

yeah i'm trying to use arrays as much as i can

kindred tusk Mar 21, 2022, 2:54 PM

#

I think creating an array of some maximum size makes sense anyway

#

If you want to generate more than that you should batch it over several frames

sinful pecan Mar 21, 2022, 2:55 PM

#

yeah, since i already know the max size of each map layer

#

and it'll probably stay the same for each, just the scale will change

kindred tusk Mar 21, 2022, 2:56 PM

#

Another thing you might explore is using a normal map instead of having that many vertices on each tile

#

Esp. for the floor tiles

#

If you want to compare performance you coudl try just rendering perfectly flat tiles and see how fast it is

#

It's quite possible that doing that would mean that you won't need to optimize nearly as much if you do that.

sinful pecan Mar 21, 2022, 2:59 PM

#

i'd definitely like to make sure i have some leeway for actually geometry, since i still want environment objects and make the place feel more alive etc.
but i'll put that in my notes yeah

kindred tusk Mar 21, 2022, 3:00 PM

#

Sure, well you can always scatter geometry on top.

sinful pecan Mar 21, 2022, 3:00 PM

#

at least i managed to keep the object count low, maybe to a fault haha

kindred tusk Mar 21, 2022, 3:01 PM

#

Well you still get batching if meshes share a material

#

In fact having one big object might be bad because it can't be culled when it's mostly offscreen

#

But chunking it should address that

kindred tusk Mar 21, 2022, 3:01 PM

#

kindred tusk In fact having one big object might be bad because it can't be culled when it's ...

(I'm not actually sure about this one)

sinful pecan Mar 21, 2022, 3:01 PM

#

yeah, that's why i was doing the culling manually

#

oh, i could also consider calculating normals beforehand

kindred tusk Mar 21, 2022, 3:03 PM

#

Yeah, I thought of that too.

sinful pecan Mar 21, 2022, 3:04 PM

#

since i'm doing hard edge low poly style anyway, so normals are always the same relationship to the face

kindred tusk Mar 21, 2022, 3:04 PM

#

I reckon you'd get pretty good mileage with 12 random normal maps just assigned at random to tiles

#

Fewer even if you rotate them 6 ways

Hey everyone, do you know how I'd be able to send data to nativ android app when I use unity as a library? I know how to send data to the unity module with unityPlayer.SendMessage(gameObject, functionName, parameter) but not the other way around. Any idea?
The purpose is to provide to the android developper some kind of event to hook to to grab data from the unity module when he needs it

#

I have done it for webgl by writing a jslib file that calls a function the web dev has to create on his side with the same name (if he doesn't the module crashes because it's trying to call a non existing function, but that's the idea)

I don't know if this is possible. My instinct is that it's probably not, although I might be unaware of something. But because of the externalized nature of the Java/Kotlin code, I don't think Unity can check for the existence of a particular member.

I'm not sure I follow the question. You will not be defining the bodies of these functions on the Unity side, he will have to do that on the Android side. You guys simply have to agree on method signatures and what the expected functionality of the method is.

maiden gull Mar 21, 2022, 4:26 PM

#

it's just that if the function is not defined on his side then it falls back to the one I made in unity where the body is empty (It also would help for apk test purpose so I don't have to disable part of code where i usually call this method when I test it directly as an apk)

should a api manager be a singleton or static or neither

#

it basically just a class that does unitywebrequests to our cms

every method is a coroutine

#

but debating how it should live

frank peak Mar 21, 2022, 4:38 PM

#

a singleton isnt a bad idea if you only need a single, easily accesible instance

#

helps coordinate actions across that system

soft hawk Mar 21, 2022, 4:38 PM

does the api manager need to remember anything? if no, you can make it a static

alpine adder Mar 21, 2022, 4:38 PM

it does not remember anything

frank peak Mar 21, 2022, 4:38 PM

#

there ya go

alpine adder Mar 21, 2022, 4:39 PM

just pure methods

soft hawk Mar 21, 2022, 4:39 PM

#

That's generally the question I ask when I'm trying to decide if I can make something static

alpine adder Mar 21, 2022, 4:39 PM

#

so static is a good option. I had a thought around just making it a normal class that one instantiates but then i was worried about thread safety with the async stuff

#

that makes sense

#

I actually currently have it as static atm 🙂

#

but could just be overthinking it to death lol

soft hawk Mar 21, 2022, 4:40 PM

#

I also suffer from that problem

frank peak Mar 21, 2022, 4:41 PM

#

ye same

#

i used singletons and still question if im making an antipattern or w/e

alpine adder Mar 21, 2022, 4:41 PM

#

say its a normal class just out of curiosity is it thread safe to have multiple instances of it

#

just in theory

#

i've really fallen in love with dependency injection

#

over singletons

frank peak Mar 21, 2022, 4:42 PM

#

hmm i wonder eh, idk

#

its mostly coroutines too eh?

alpine adder Mar 21, 2022, 4:42 PM

#

its all coroutines

#

basically think usermanager.getuserprofile

#

or usermanager.updateuserprofile

#

etc

soft hawk Mar 21, 2022, 4:43 PM

#

Wait so its a Monobehavior?

alpine adder Mar 21, 2022, 4:43 PM

#

it is not

#

userclient.getuserprofile

#

i mean

midnight violet Mar 21, 2022, 4:44 PM

#

It inherits from mono then because of coroutines?

alpine adder Mar 21, 2022, 4:44 PM

#

so the monobehaviour class calls startcoroutine(useclient.getuserprofile)

#

this is just a pure class that holds the methods

soft hawk Mar 21, 2022, 4:46 PM

#

I might be wrong but I thought the class containing the coroutine has to inherit monobehavior

midnight violet Mar 21, 2022, 4:46 PM

#

Oh okay, you use the class as palceholder mono for your static

alpine adder Mar 21, 2022, 4:46 PM

#

it does but this does not technically use the startcoroutine function

#

just holds the Ienumator method for it

#

exactly @soft hawk

#

its just a library of methods really that monobehaviours call

midnight violet Mar 21, 2022, 4:48 PM

#

Your question was, if API Manager should be static?

alpine adder Mar 21, 2022, 4:48 PM

#

basically

#

it does not inheret nor need a monobheviour either

#

forgive the spelling

midnight violet Mar 21, 2022, 4:49 PM

#

So right now I am working on a system and I put my managers as normal monos but with static delegates, params and what not to make them easily accessable and not having that .instance. thing goin on

soft hawk Mar 21, 2022, 4:50 PM

#

So I guess my previous statement is wrong. I don't know why I thought that?

alpine adder Mar 21, 2022, 4:57 PM

#

a class that needs a coroutine does need to inherit from mono, or use editor coroutines

#

but the Ienumator is built into the c# language so that doesnt

#

If I have a IEnumerator coroutine with waits, and I call it as a method, what happens?

what do you mean by waits?

soft hawk Mar 21, 2022, 5:01 PM

WaitForSeconds()

alpine adder Mar 21, 2022, 5:01 PM

you can do a yield return for the method

@soft hawk what is your objective?

FindAllMegaBlocks();
this is an IEnumerator FindAllMegaBlocks() ?

soft hawk Mar 21, 2022, 5:03 PM

#

Well sometimes I want it to wait, and sometimes I don't (when AI is evaluating future moves)

#

no that's the coroutine I have, EvaluateBoardCoroutine()

undone coral Mar 21, 2022, 5:04 PM

#

StartCoroutine(MethodReturningIEnumerator()) does not wait
yield return StartCoroutine(MethodReturningIEnumerator()) waits for the coroutine MethodReturningIEnumerator to finish

soft hawk Mar 21, 2022, 5:05 PM

#

Right I get that, but if I just had a call to
EvaluateBoardCoroutine()

undone coral Mar 21, 2022, 5:05 PM

#

MethodReturningIEnumerator() returns an IEnumerator. no code will execute unless you interact with the returned IEnumerator instance. the best way to "interact" with it is using StartCoroutine()

soft hawk Mar 21, 2022, 5:05 PM

#

Oh ok

undone coral Mar 21, 2022, 5:05 PM

so your conventional bot should have something of the form

#

There are three main parts: Move generation, Move Evaluation, and then pathfinding. That part is simple

undone coral Mar 21, 2022, 7:10 PM

#

while (gameStateStack.Length > 0) {
 var v /* as in vertex */ = gameStateStack.Pop();
 if (isTerminal(v) { compute score and set it on the vertex }
 if (isInterruptedOrRunsOutOfTime()) { exit }

 var depth = v.depth;
 var edges = v.context.validMoves();
 if (edges.Length == 0) continue;
 
 foreach (var edge in edges) {
  executeOneMoveOfGameAndAppendNewStateToStack(gameStateStack, v, edge, depth);
 }
}

#

@soft hawk does this make sense?

#

it is depth first depending on how you append the state to the stack

#

to make this parallel

#

the foreach is replaced with...

Parallel.ForEach(edges, edge => {...})

#

that's it

#

do you know what a greedy algorithm is?

soft hawk Mar 21, 2022, 7:14 PM

#

Im sure I knew when I did this in college, but that was a long time ago lol

#

But your pseudo code sort of makes sense to me, and I should probably refactor my solution to look like that

undone coral Mar 21, 2022, 7:14 PM

#

you only expand the game state with the best score

#

instead of expanding them all

soft hawk Mar 21, 2022, 7:15 PM

right, does it matter that evaluating the gamestate (getting a score) is destructive?

"[destroying the game state by getting a score] was a mistake"

soft hawk Mar 21, 2022, 7:16 PM

#

well I can always make a copy of the board

undone coral Mar 21, 2022, 7:16 PM

#

yes

#

you will have to make a copy of the board

#

you should represent your board as a struct with fixed size arrays

#

otherwise you will spend like 20-40% of your CPU time copying game states

#

you will need to do this anyway if you want a hope and a prayer of making the deep learned agent work

#

which is the whole reason i told you to try writing a conventional bot first!!

#

and now look at you

#

look at you thrive

soft hawk Mar 21, 2022, 7:17 PM

#

So right now my board is a class with a Block[] array

#

But I could just make the block array a struct

undone coral Mar 21, 2022, 7:19 PM

#

it has to be a fixed array and you should use unsafe

#

you will see this online

soft hawk Mar 21, 2022, 7:20 PM

#

Ok i think I get that

undone coral Mar 21, 2022, 7:20 PM

#

someone more knowledgable will have the answer online

#

for how to declare a struct that contains a fixed size array you can copy easily

#

and how to do that copy

#

you should look what a greedy bot is

soft hawk Mar 21, 2022, 7:21 PM

#

This gives me good direction, thanks

#

I might not even need to bother with multithreaded

#

The bot does pretty well even at just depth 4

#

@undone coral Ah ok, So a greedy algorithm probably doesn't work in this case

#

Because you get big bonuses for setting up chains of blockbreaks

#

So the greedy move is not necessarily the best move in this game

#

I have incentives that help the bot naively pursue organized board states and avoid losing board states, but I'm not sure how I'd balance those incentives to make a greedy algorithm effective

undone coral Mar 21, 2022, 7:41 PM

#

you can also prune

#

heuristically

#

until you've
 - run out of game states
 - run out of time

prune the game states you want to evaluate
get a vertex in your DAG
finish a terminal one - score it and record its predecessors.
otherwise, expand it by appending the game states onto your
 stack created by taking all this vertex's actions

#

you can also change the order you evaluate the game states in

#

you don't always do depth first

#

you can order it greedily

#

to save time

#

OR maybe in this game the worst move tends to be the best one to start with

#

so do it a different way

#

@soft hawk does that make sense?

#

i haven't looked, but puzzle fighter might be solvable?

soft hawk Mar 21, 2022, 7:44 PM

#

Not sure what solvable means in this regard, since its an adversarial game

#

Right now im just using score as a heuristic for success

undone coral Mar 21, 2022, 7:54 PM

soft hawk Mar 21, 2022, 9:33 PM

#

@undone coral So I need to make my Block structs out of blittable data-types and the Board is then an (unsafe) fixed array of those Blocks, and that will be compatible with the jobs system, is that right? I've been reading a lot of stuff and trying to map out my next steps

#

That will make a Board a non-nullable array of structs containing blittable data types only

undone coral Mar 21, 2022, 10:22 PM

#

the board should be a struct

Right, ya

simple pruning strategies:

symmetry (are moves A-B the same as B-A)
score (remove the lowest N scores)

#

do you model what the opponent does?

#

you have to assume they maximize their score

soft hawk Mar 22, 2022, 12:15 AM

#

No because they're fairly disconnected, its not they move you move

#

both play simultaneously on their own gameboards, scoring points "attacks" the other board with random pieces

the idea is to make the other guy game over before you do

the attacks are not predictable so there is no point in modeling them here

Hello, i have a slight problem, i have a method converting world coordinates to grid coordinates (the game is 2D and i use a grid for it) and it works as intended with a slight exception:
(int)(WorldPosition.x / CellSize.x) expression returns 4, when WorldPosition.x is 3.2 and CellSize.x is 0.64
I already thought about WorldPosition.x being just a bit under 3.2 so the overall expression would result in 4.99 aprox. and it would then get rounded down to 4, but the VS code debugger shows a clean 3.2 value for it, and the code works for other values(such as WorldPosition.x being 1.28, or equal to 2 in grid position)
anyone got any ideas? I can share the whole method but I doubt it would provide further insight as WorldPosition and CellSize are not modified in the example i used.

it's probably getting rounded for display

and is actually just under 3.2

compact ingot Mar 22, 2022, 1:51 PM

#

also, just so you know (as an example), 3.2f is actually 3.20000005f when assigning it directly in code, so it is likely that your world position is actually not exactly 3.2 (due to compound errors in its transform calculations) and thus your math doesn't work.

#

with direct value assignment the calculation works, so there is no other explanation

sly grove Mar 22, 2022, 1:59 PM

#

compact ingot also, just so you know (as an example), 3.2f is actually 3.20000005f when assign...

thre's no need for compound errors to cause this one. 3.2 is just not possible to represent in binary with a finite number of digits

#

same way 1/3 cannot be represented in decimal with a finite number of digits

compact ingot Mar 22, 2022, 1:59 PM

#

yes, but as you see in the calculation the error when assigning 0.64 corrects it and you get a perfect 5

#

well if 3.2 is like 3.200000005

granite viper Mar 22, 2022, 2:00 PM

I think the point is that it has to be less than 3.2 to cause a result of 4

sly grove Mar 22, 2022, 2:00 PM

interesting

granite viper Mar 22, 2022, 2:00 PM

#

that's where the error comes in

serene girder Mar 22, 2022, 2:00 PM

it should round down to 5 when divided by .64

granite viper Mar 22, 2022, 2:00 PM

#

3.200000005 is greater than 3.2

#

so in other words, your 3.2 is not 3.2 @serene girder and is actually ~3.19999

you could throw down with this: https://docs.unity3d.com/ScriptReference/EditorApplication-hierarchyChanged.html

it's not much and it might be a bit hacky, but it's something you could start with. keep track of the objects in the hierarchy. when it's changed, compare the new list of objects with the old and pinpoint the new one. Then create a new GameObject and parent that object to it. Then duplicate it as many times as you want. Lol it might work!

I have legit one of the weirdest bug yet I found.
I have 0 clue if someone even remotely knows whats going on here.

tdlr: One of my weapons is not beeing rendered if it's not visible in the scene view in the editor????
I checked both models and they appear to have everything the same in terms of settings.

How does that even happen? Why does the scene view effect rendering in the game window?

Sceneview is basically another camera that will trigger onrender, onbecomevisible and so on functions when being used in scripts.
