hey guys

wait

wrong chat

my bad

[raw warren]

My dudes, I cant instal monogame directly on Visual Studio

Halp pls

[hot hazel]

gonna need more details

[hidden shell]

Hello, I'm having trouble creating a deterministic, fixed timestep game loop.
Here's a pastebin for how I'm trying to limit my # of physics steps to 15 per second: https://pastebin.com/TgVyDvib

The code displays the ticks per second to console every second.
What I expect is for it to always display 15. However, sometimes the ticks per seconds is 16 instead of 15.
Is the reason it's sometimes running an extra update per second due to rounding issues? I can't seem to figure it out

[lament gyro]

I'd asume some float rounding issues too.

you defenetly suffer from precision loss. Maybe do something like devide the System time with your time step.

[raw warren]

https://www.twitch.tv/dj_c_wied

[quiet ibex]

@hidden shell its impossible to guarantee 15 updates per real second. fixed timesteps only guarantee that each step has the same length and it pauses between steps or run extra steps to keep it roughly in sync with the real time

the virtual time is what's updated in fixed increments

[sand pumice]

any good tutorial for monogame devs

[hot hazel]

look up xna tutorials

[sand pumice]

thanks

[lament gyro]

I know "don't ask" but, has someone experience with Aether.Physics2D?

[flat osprey]

Hi all, small problem, Was hoping somebody could help with. I made a dictionary<string, int> to hold player stats. Strings for the names of a stat and the int for the value of the stat. How would I go about modifying the dictionary values from another dictionaries<string, int> values? Thanks

[quiet ibex]

@flat osprey dictionary["foo"] = bar;

but are you sure you want stats in a dictionary? you need to attach logic to them or they'll be useless

so unless you need a data-driven map between stats and logic, it seems more logical to make strongly typed stats

[flat osprey]

Yeh maybe i'm going about it the wrong way, I thought I could just use dictionaries to hold each races, class and players stats then modify the players values where keys match the race / class 's key

[quiet ibex]

well you could, but you wouldn't get value from the dictionary if the number of items in it didn't differ a lot between objects

[flat osprey]

Mind if I pm just show what i'm doing as to not spam here?

[quiet ibex]

so why not make a Race and Occupation class? they could then be referenced to define a Hero class for instance

might as well put it here, someone else might learn something

[flat osprey]

Well yeh, I made race classes and "class(like rogues, mage ect" classes that have 6 stats, Rather than running through them all to add to the players I wanted to store them in a collection so I could just run a loop when modifying the players stats

[quiet ibex]

ok, sounds like you've defined new classes where you really just needed new data

[flat osprey]

So I want the player to have these stats all set to 0 then if they choose to be a human then all the human modifiers are applied and then they can continue to choose a race and then thats use to modify them

[quiet ibex]

you can probably define 1 class to cover rogue/mage/etc

[flat osprey]

Well I made a race class and a classType class, Then with each race and class I made new classes than inherit from them because later I want to add more stuff to each of them, abilities ect..

[quiet ibex]

i wouldn't inherit from them until it proved necessary

you want to focus on the data when designing a class hierarchy, much like when normalizing a database

from what i've heard so far, you have at least 3 classes. Race, ClassType(would swap this for Occupation to make the naming clear) and Ability

you might also want 2 Modifier classes, one for additive modifiers and one for multiplicative

and you'll need a class that describes the actual ingame entity, i usually name it Hero to avoid conflicts with Player(usually useful for controller mappings, etc.) and Gamer(often used for steam integrations and the like)

i also tend to have an Enemy class and have both it and the Hero inherit from an abstract Actor that's the base class for anything interactible

the actor could then contain all the logic needed to calculate effective stats from bonuses and modifiers

[flat osprey]

I get what you're saying but I don't know what way to handle the stats for each race ect.. What collection would be best for this situation?

[quiet ibex]

doesn't really matter, you're probably going to pick the race from a list in a menu, so an array would work fine

i'd define the races in a csv file for simplicity, that way they diff nicely in source control and you can do mass-edits in excel

CsvHelper can do the parsing in a couple of lines

[flat osprey]

So for example just give the human an int array0-5, How would I pick out the stat though, Like I'd have to know what cell each attribute is supposed to be, This is why I was trying to use dictionaries because the key can be the name and value is well.. the value

Ah

[quiet ibex]

i'd just put the base stats as columns, which means the race class gets a property for each

[flat osprey]

See this isn't supposed to be anything big, Just a small console game so I can practice programming.. Just realised.. Why not just create a database lol ffs

Appreciate you taking the time to help bud 🙂

[quiet ibex]

yea, the csv files essentially becomes tables in a database. but there's a big advantage to using them over an actual database, since they diff nicely in source control

so you can do branches testing out balancing fixes and then cleanly merge them without conflicts

[pseudo sigil]

Hey folks! I have a quick question. I'm writing a game in monodev and it's an online multiplayer type deal. Does anyone have any good links on server-side collision? Any help would be much appreciated, I haven't been able to find much personally.

[quiet ibex]

@pseudo sigil its no different from any other type of collision detection

[sturdy prairie]

how inefficient is it to make a draw call using a texture atlas like:

sb.Draw(texture_atlas, hitbox, texture_atlas.GetByID(1), Color.White);

as opposed to making a method with the texture_atlas that creates a texture from a selected region?

[hot hazel]

the sb.draw would be way more efficient if im understanding you correctly

[sturdy prairie]

well both are sb.draw

so I'm not sure which one you're talking about

[hot hazel]

what do you mean 'creates a texture from a selected region'?

[sturdy prairie]

I mean like

so the texture atlas is a giant Texture2D

I would have a method that looks like this

public Texture2D GetTexture(Rectangle source)
{
    //code that takes texture_atlas and returns a new texture that is the region implied by the rectangle
}```

does that make sense?

like it crops out the section of the texture atlas and makes a new texture from it

[hot hazel]

my point is in monogame

new textures would be individual pieces of gpu memory

spritebatch, hence the name, batches draw calls i believe only by texture

so if you are switching textures, you lose all benefit

that is the purpose of the sourceRectangle in SpriteBatch.Draw

[sturdy prairie]

so it would take less memory by certain

what about gpu power though?

[hot hazel]

if you create two textures

when you draw something it has to bind that texture

then if you wish to draw a second texture it has to bind that

(in addition those are multiple draw calls)

modern dx/gl can do bindless textures, but i dont think monogame supports that and i dont know enough to talk about that

its basically no different from rendering a 3D mesh with a texture

the reason atlases exist is to be faster and smaller than individual textures

[sturdy prairie]

so hands down it's faster

awesome

thank you!

[hot hazel]

also easier

[sturdy prairie]

definitely

thanks @hot hazel

[restive tapir]

Osuology gave karma to CobaltHex

[hot hazel]

anyone have experience with debugging opengl shaders for monogame? getting program crashes when certain shaders run, and theres no debug output

[hot hazel]

figured it out. unless im doign something special, one cannot have more than one position per vertex

[quiet ibex]

you can have multiple uv coordinates and other features, but multiple positions makes no sense

[hot hazel]

Dx supports them, I was using for misc vertex data

I guess the question is should I put the stuff in a texture instead

[surreal cobalt]

ok so this sounds weird but I want to have a 3d rendered item in a 2d space

like, it's only a visible difference to the viewer

[hot hazel]

Everything on a screen is 2d

Gonna need more details of what you want

[surreal cobalt]

so for example

floors and stuff are 2d

but walls are 3d

like pretty much everything but walls are 2d

actually I'm just gonna figure stuff out on my own and be less dumb with questions

[flat orchid]

hello

i am interested in the ways of the monogame™️

i've seen some few code bits and some unity knowledge transfers over to here

is it true?

do the same barebones rules mostly apply to both

[hot hazel]

monogame is only a framework

so while it does provide some things like a simple model renderer and spritebatching it doesnt require you use them and they are otherwise pretty barebones

it doesnt really dictatate how you build anything

so anything you did in unity you'd have to do in monogame

but you'd also have to do most of the stuff unity did for you

[raw warren]

@flat orchid I prefer Monogame over Unity because I have so much more control over my project. A big downside is that there’s no GUI. It’s just code

So it’s up to what you prefer

[flat orchid]

Wdym there's no GUI?

@raw warren

No integrated UI library?

[raw warren]

No no

There’s no gui for the person working on it. Like how Unity has its workspace. You just type code into your IDE (I recommend VS). You don’t drag and drop assets or anything of that sort

Kyle Schaub has a great tutorial on Udemy that covers both C# and MonoGame

Hope that helps @flat orchid

Keep in mind that MonoGame is primarily for 2d

Unity is better for 3d, but not so great for 2d

[hot hazel]

you can use monogame for 3d no prob

again, you'll be doing 90% of the work yourself however (or find a library)

[raw warren]

Well yeah

It’s just more efficient to use Unity

[hot hazel]

i wouldnt call it efficient

just easier

[gray matrix]

hey guys i just got started with MonoGame this weekend, are there any good tutorials for how to change scenes? like from splash screen to main menu?

[hot hazel]

monogame/etc dont dictate anything about how you do that

e.g. my game does not use scenes

so its up to whatever library you're using really

[quiet ibex]

@gray matrix what you're looking for is documentation on how to manage game states. A simple version would be having a class for each state(scene) and call update/draw on it through the Game1 class

the update method could then return a string/enum indicating the next state to switch to and then do a switch statement that swaps out the active state in the beginning of Game1.Update

its important that you only swap states in the beginning of update though, otherwise you might end up drawing a junk scene that hasn't been updated yet

[gray matrix]

wait what? are you saying i should be using the same Game1 class to render ALL my stuff with just different game states?

[hot hazel]

in my game i have a map class thats basically the game renderer

it itself is just a UI component

my main class renders the UI and the UI can update what UI is drawing

so they UI could be menus, the game, the editor, etc

[raw warren]

Hey guys! I have a question related to Monogame and Unity, I thought asking here would be the best place, do let me know if it's not :P

I am a decent programmer with a decent background and I recently started my own game project. Game development terms and structure is not unknown territory for me, however it is my first real game project ever, while intimidating I still feel confident about it 🙂 We're making a multiplayer 2d game with a top-view camera.

As the lone programmer of the project, as of right now (In the process of getting a second one), I am faced with quite a difficult question which is "Should we use Unity or something like Monogame?". I've read alot of articles, reddit posts and messed around with both Unity and Monogame. However, I'd like to get a more direct input with my situation in mind.

We've been using Unity for the past month or two, however my feeling is that Unity is taking care of a lot of things for me in a way I don't necessarily like, but also brings alot of tools to facilitate the workflow between programmers and artists as well as making things easier for me. As I'm working with pixel artists mainly using Aseprite, using Unity's built-in tools to process spritesheets and create animations has been a charm as we were able to quickly see results in a somewhat playable state.
While this aspect is great, as a programmer, I'm feeling forced to follow Unity's pattern which I don't necessarily like and Monogame definitely allow me to do whatever the hell I want and ultimately, gives me a lot more control as to what's going in the game compared to having to work with Unity's pre-made abstraction.

While that last paragraph would totally convince me to use Monogame over Unity, my main concern is the workflow between programmers and artists and the overall additional dev time required if I go with the monogame way. What is your guys opinion on that? Have you ever been faced with this situation or ever thought about it?

Thanks 🙂

A good analogy I came up with while thinking about this whole thing was "Do we want to use a lego box with pre-made parts that we only need to connect together or do we want to take the massive box of regular legos"

[cold pilot]

is it possible to do webapi calls using monogame? trying to figure out if I can port some server stuff from gms2 to monogame

[quiet ibex]

@raw warren depends on the game, it's possible to have monogame be the quicker implementation option. but you do need to know what you're doing

and given that you're looking for a second programmer and asking this question, you probably don't

[raw warren]

That's quite the harsh answer to reply with "You need a second programmer so you don't know what you're doing"

[quiet ibex]

unity is no walk in the park either though. it takes strong management and a disciplined team to work efficiently with it

[raw warren]

And the reason i'm getting a second one is because I can't do all the work alone honestly, a second mind to think about things and figure out stuff as we go on is always better

[quiet ibex]

that's not what i meant, i was commenting on the fact that you're looking for a programmer and you don't have the answer to the questions posed here

[raw warren]

Ah! I understand now, sorry about that assumption.

With that aside though, I agree, Unity is no walk in the park either, I don't expect Unity to be easier in fact.

[quiet ibex]

its also very important that you get the right person for the job, or adding another head is only going to slow you down

conversely it also means you need the skills to work effectively with a team

[raw warren]

Which is understandable, and I totally agree. I'll keep that in mind for sure. If we take the second programmer out of the equation however, what is your take on my concerns? Would you recommend one over another?

[quiet ibex]

for a solo 2d project i'd lean towards monogame, simply because you can get stuff done well in it far quicker

unity is better suited for teams of 5-10 ppl

[raw warren]

Interesting take, I never thought about the team size being a factor of what to choose honestly. I do have a couple people with me focusing on art since the project will require a lot, with that in mind, Unity would be a wise choice to keep that workflow clean I assume. My main concern however, since this will be a learning process for me on making an actual game (I've only made mods for existing games so far), is that using Unity may not allow me to fully understand how my game would work and not entirely having control on it.

I feel like this is a decision between "Controlling my code" and "Having great tools out of the box"

[quiet ibex]

your artists shouldn't be directly interacting with the engine while they work. The should be sending their assets into the pipeline and the rest is up to you pretty much

unity doesn't have "great tools" it has lots of "good enough" tools. which is why you can work quicker with monogame, if you know what you're doing

unity was designed around a process where decisions are made ahead of time in a meeting, followed by 1 or more teams spending a day or 2 implementing the decision into the game. That's not a quick workflow for a small team

[raw warren]

Now that you mention it, I do see that process in Unity now, hence why I felt like the code I was writing wasn't really "satisfying" if that makes any sense. I do see the upsides of Monogame alot more now, when starting out I assume I will write a lot of code to get the game working but in the long run, implementing new stuff would be easier since all of the code will be for my game and only my game compared to Unity which targets "A game in general". Correct me if i'm wrong

And "Good enough" tools is indeed the right term 😛

[quiet ibex]

well monogame just brings you to a lower level of abstraction, so you can implement your game using conventions and policies as opposed to hand-tweaking individual attributes

which means 1 man can do what it normally takes 10 people to do. as long as he knows what he's doing

but it also means you can't throw resources at a problem to make it go away

[raw warren]

That makes sense! Thanks for your insight, it was very helpful, I know what I'll be studying from now on 🙂

thanks @quiet ibex

[restive tapir]

Raphy gave karma to Ragath

[raw warren]

I'm definitely open to more opinions should anyone else want to throw their 10 cents as well 🙂

[hot hazel]

2 cents?

following along ragath's statement

unity provides a lot of things for you

however if you want to do things differently, you're fighting unity

monogame does less for you, so theres less to fight

so it really depends on if unity works the way you want it to

how to change window size? (libGDX)

[lone radish]

I'm working on a space game, I have a problem with the planets and the star moving during warp. They both use the same class for movement but somehow only the first of them that's being updated moves

[lone radish]

I fixed it

[raw warren]

how to change window size? (libGDX)
@raw warren buy 4k screen

@raw warren buster

[distant perch]

the Lwjgl3ApplicationConfiguration has a setWindowedMode(<width>,<height>)

[raw warren]

@distant perch HOW?

i need example, i really dumb in this damned api

[distant perch]

your talking about the size of the window when running as a desktop app, right?

[raw warren]

yes

but i want create app for android

[distant perch]

so you probably have some Lwjgl Launcher class that looks a bit like that:

public class Lwjgl3Launcher {
    public static void main(String[] args) {
        createApplication();
    }

    private static Lwjgl3Application createApplication() {
        return new Lwjgl3Application(new YourGame(), getDefaultConfiguration());
    }

    private static Lwjgl3ApplicationConfiguration getDefaultConfiguration() {
        Lwjgl3ApplicationConfiguration configuration = new Lwjgl3ApplicationConfiguration();
        configuration.setWindowedMode(1234, 123); // <- where you can set the default window size here
        return configuration;
    }
}

[raw warren]

i talking about libgdx, man...

[distant perch]

I know, that's the class that launches a libgdx game

import com.badlogic.gdx.backends.lwjgl3.Lwjgl3Application;
import com.badlogic.gdx.backends.lwjgl3.Lwjgl3ApplicationConfiguration;

[raw warren]

BRAINCRACK

[distant perch]

how does "DesktopLauncher" look like

[raw warren]

package com.mygdx.game.desktop;

import com.badlogic.gdx.backends.lwjgl.LwjglApplication;
import com.badlogic.gdx.backends.lwjgl.LwjglApplicationConfiguration;
import com.mygdx.game.Drop;

public class DesktopLauncher {
    public static void main (String[] arg) {
        LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();
        new LwjglApplication(new Drop(), config);
    }
}

[distant perch]

well there you go

[raw warren]

oh im stupid

[distant perch]

add
config.setWindowedMode(something something)

[raw warren]

ok i understand

facepalm

[distant perch]

😉

[raw warren]

@distant perch the configuration has only 2 setters

[distant perch]

try

config.height = 480;
config.width = 640;

[raw warren]

frameworks are too complex for my brain

@distant perch this works

thanx man you have quantum brain

[distant perch]

if you want to change the window size while the game is running you can also call

Gdx.graphics.setWindowedMode(width, height);

but since you mentioned you wanted to code for android as well I would check before calling that if it's not on android (changing the window size on android doesn't make much sense)

if (!Gdx.app.getType().equals(ApplicationType.Android)) {
    Gdx.grpahics.setWindowedMode(width, height);
}

[raw warren]

also works

where do you learn about all these methods?

[distant perch]

just playing around with it and if I'm stuck, asking people on discord

but the libgdx wiki is not too bad https://github.com/libgdx/libgdx/wiki

[raw warren]

@distant perch okay, thanks)

[restive tapir]

DannyWarp gave karma to this_is_phil

[lone radish]

I need help

if you look closely(might be too bad resolution) the planet vibrates when I move. You can se the stars flickering in the lower left. I don't understand why i vibrates. I can provide the code for the movement

[quiet ibex]

@lone radish that's because of improper handling of subpixel positioning

[lone radish]

What now?

I am rewriting the whole thing tho

I am making it a render target instead

[quiet ibex]

you probably had a blurry render and then set the samplerstate to pointclamp

[lone radish]

I was printing it directly to device

[quiet ibex]

a pointclamp samplerstate is not good enough to deal with this on its own

[lone radish]

But I have another problem now

Wait

Tell me about the subpixel thing @quiet ibex

[quiet ibex]

@lone radish basically the pointclamp filter can make pixels disappear if you try to draw them between screen pixels

its also why it looks like the thing vibrates

[lone radish]

I don't use a samplerState at all

The planets don't vibrate anymore but the stars do dissapear from time to time

[dense sable]

What should you do in this case?

I think I have the same problem

I don't know if it's visible enough but when the camera moves in a horizontal or vertical momement it's ok but not with diagonal movement

[quiet ibex]

@dense sable there's no one size fits all solution for this sadly, one option is to render different things on different "pixel grids"

i've done that in a game where the camera is fixed to the player and the rest of the world is rendered to a render target that's then aligned to make the camera movement completely smooth

the player sprite can be positioned between 2 background pixels in that case though. so it's not a pixel-perfect render

[dense sable]

I'll consider using two different render targets, but I don't really see what to do to have a smooth camera movement

i feel like now it's just doing ←↓←↓ pixel by pixel

[hot hazel]

I think the idea is that you can move the render target at partial pixels, but it may look blurry so only use it for the backgrounds

[orchid perch]

I recognize that name...

Anyway, one simple solution to this week-old discussion is just to always render everything at exact pixels. Just... round them off.

Intuitively it would make things jitter but in practice it looks good.

[quiet ibex]

@orchid perch no that's what he has and it does noticeably jitter

it's just such a common problem, that people go "omg, i didn't know things could look this smooth" when you get it right

[orchid perch]

Yeah.

Jittering means you're either jumping back and forth, or in pixel steps of alternating lengths.

If everything is floating point and you only floor it for the final render it usually works out.

My suggestion is always if you're making a pixel-perfect game to work in pixels. I actually am using integer position values at all times and I think I got the motion right. Could do a write up on it.

[timber mesa]

after joining a game jam and realizing with horror that I had no idea how to architect a game I looked into some ways to structure a game; libgdx comes with an entity-component system plugin that I'm currently playing around with but I have a question: components are supposed to contain "data" and not "functionality".

But how strict is that? in Kotlin, which I'm using for my playing-around, functions can be treated like data. It's cute, but is it "actually" data? What happens if I put a field for a function from say, integers to integers into a component's constructor (not as a method, just as raw data)? What goes wrong? Does this kind of thing have undesired side effects? And if there is a channel to ask questions in better than this one, which one is it? Thanks!

[raw warren]

In general, most ECS's don't literally enforce the data-only components, but it's in the purpose of the ECS design itself that components be only data so they have as little overhead as possible.

In concept, data is simply values that are stored. floats, ints, bytes, data that's read/written to.

I'm not sure what you mean by functions getting treated like data, unless you're talking about delegates/function pointers. In which case, yes, in theory, a delegate/fp is just like any other data, and will be modified/reinterpreted in undefined ways if you treat it like other data types. However, there's nothing inherently wrong with passing those around.

[quiet ibex]

@timber mesa when you bundle logic and data, you end up eliminating the reusability benefits of the ECS

im newbie to monogames

[marsh palm]

Does anyone know a good tutorial for Tower defence games in monogame?

[digital dragon]

I don't think there is a tutorial specific to tower defence, but if you look for XNA tutorials you will find a lot. Most of the stuff described for XNA still applies to monogame

the monogame documentation lists various sources for tutorials as well

https://docs.monogame.net/articles/tutorials.html

[marsh palm]

Thanks

[quiet ibex]

@marsh palm it's tough to find tutorials for specific games and tech combinations. but you should have no trouble finding info about how tower defence games are constructed and then you can more easily look up how to do the specific things in monogame

[glacial hull]

Hi guys, sorry, maybe my question is not for this channel, but I can't find where I can ask )) So I am Manual QA Tester and now testing games based on libgdx and want to start automate my tests and don't know which tools I can use for it, I saw many tools for mobile automated tests but idk is there match for gaming, if you can give me advice or provide to the right channels it will be very helpful for me )))

[azure geode]

You might need to create an interaction layer that allows you to simulate inputs within the game and use a standard automated testing suite.

[quiet ibex]

@glacial hull if you want the test to be more than a glorified keyboard macro, you're gonna have to talk to the devs and establish an architecture that allows for testing

and it's usually not viable to replicate an entire testing session with some scripts

[glacial hull]

Yep also think about it, thank's for advice

I'm using FMOD with MonoGame and I used the aforementioned github link. However the latency is awful :(

Oh. wait. I'm actually not using that link. I started using that, but I switched to the FMOD c# bindings when I wanted to decrease the dependencies of my project. The FMOD installable api includes the C# bindings.

[flat orchid]

why this though

like

this is from the tut, i'm telling it to search in content yet the command goes through nectoreapp31

oh i just needed to build lol

N I C E

it works

@frigid fiber how do i link an fspro project to monogame now?

i'm guessing you've managed it

[frigid fiber]

@flat orchid You have to build the .fspro (F7, I think) from FMOD Studio. Then it generates 1 or more .bank files.
Then you use FMOD.Studio.System.loadBankFile () to load those .bank files

[flat orchid]

thanks a lot @frigid fiber

Is there an easy way of getting MonoGame to work with MonoDevelop?

[hot hazel]

In what way?

[flat orchid]

download the monogame api and import that in monodevelop

sounds like it makes sense

or nuget package(?)

if monodev has those, idk haven't used it

[hot hazel]

can also clone it off github/download release

you just need to link in the assemblies

[raw warren]

MonoGame is integrated within MonoDevelop, but it's broken

that's why I was having issues

[hot hazel]

i use VS, but don't use the integrations, I just link it from nuget

[raw warren]

yeah it works fine with VS on my old laptop

but my new laptop is running ubuntu

so I just didn't know if anyone had an easy fix for it

that's all

[hot hazel]

does nuget not work?

[raw warren]

I'll give that a shot

I'm not sure how that will interact with the MonoDevelop that's already there

[hot hazel]

I think it prefers the nuget versions but either should work hopefully

[quiet ibex]

@raw warren guessing you're using the Linux version of MonoDevelop? it's about a decade past it's expiration date, unless someone picked it up after xamarin

[hot hazel]

vs code might be sufficient

[raw warren]

ok

thanks all for the help

i started using monogame today and it's gotten me to learn a lot about how it works further down to the metal

Hi, I have a question about libGDX. To make a long story short, a few months ago I found Unity very limiting and I switched to libGDX and it's really great. I love the code freedom and cleanliness. I want to continue to develop in libGDX, but there is one thing that concerns me the most... Is it possible to make a good looking 3D game using libgdx?

what you think?

[hot hazel]

assuming it lets you create your own shaders and supports e.g. multiple textures, then yes of course

it will be a lot more work to make it look good over what unity provides out of the box however

[upbeat pendant]

technically it allows us to create shaders. There is even some shader lib. But this still looks poor compared to the default Unity scene... So I wonder if there is any good looking game made with libGDX which I could refer to as a proof of concept?

For me Space Haven is so far best looking game made with libGDX, but is 2D and completely different art style

[plain quartz]

How to build game in visual studio using monogame ?

[rocky shard]

Hey fellow MonoGame developers, I have a real puzzler for you. The first (and rarely, also the second) time that I start my game every hour or so, nearly all of my textures are black. I'm loading my textures from a packed spritesheet created with TexturePacker, and from what I've noticed, the only images that load successfully are from one specific folder: images/entity/monster. Here are some images so you can see what I mean. This is a very difficult issue to debug because after it happens once, it takes around another hour before it will randomly happen again.

I'm really stumped on this, so any tips at all would really be appreciated. This happens no matter how/where I run it, as far as I can tell

[quiet ibex]

you just have to comb through your code for bugs, make sure everything is meticulously planned out and work exactly as intended

[hardy jolt]

It seems a nice game, I didn't know it at all. I will add it to my Google Sheet of (mostly 2D) indie games sorted by engine used: https://docs.google.com/spreadsheets/d/1z1RV6w4HjPODFcao34h72Vw-9KxtQ9rv0ZM7folTUMU/ 😉

[orchid frigate]

Hey everyone,

I do write a game and do use a entity component system model for this

I do have the following parts for the core of the structure

EntityManager
ComponentManager
EventManager

And a wrapper to get a central access point for everything.

Now I was thinking how I could use UI to show data to the player because the gui is not connected to the ECS right now and everything I read told me better don't enforce the gui system into the ecs. My idea was to register the gui elements into the EventPipeline and push status changes throug the pipeline to the display.

What do you think about this approach?
I would create a "GUISystem" which catches those events updating the gui data. But since the gui is not using the rendering system from the ecs it kind of breaks the idea of a central system which manages everything.

https://pastebin.com/9x5dA7Vf <- Button
https://pastebin.com/ZQQaYAts <- underlaying class
https://pastebin.com/26E0PEDd <- if you want to go deeper
https://pastebin.com/FewznHv9 <- another class to go deeper

All ui elements are build on this base

[hot hazel]

What is the purpose of component manager?

[hot hazel]

@orchid frigate you seem to have a lot of indirection

also a lot of your doc comments leave more questions than answers

[orchid frigate]

I do use it to manage the components for the ecs

It also does pool the old already used components so I can reuse them to prevent the gc.

That the docs are missleading and not really helpful is bad,sorry I do need to improve it.

Do you need more information?

[orchid frigate]

Yep I do need to refactor this as soon as all the GUI elements I need are written

[hot hazel]

Components are typically structs, if you're storing in an array that shouldn't be an issue

[orchid frigate]

I do store them in a list one for each type to increase the performance 👍

But still my question to seperate the GUI completely from the ecs is this a good one?

Not sure how to integrate it into the ecs otherwise

[hot hazel]

while some composability is nice in a GUI, it doesn't really make sense to have it as a proper ecs imo

its very hierarchical

if you want an ecs for your gui id say it makes more sense to have your gui itself be its own ecs, and then if you need your entities in game have components that refer to entities of the GUI

as they don't have any overlap otherwise (your UI entities should data bind with the game but that should be the extent of the relationship)

[orchid frigate]

Thank you very much I will try to implement this 👍

doable, but not sure its worth the complexity

How difficult would you say learning monogame is compared to other frameworks like pygame, and if it is more difficult what features or unique attributes does it have that sets it apart form others like pygame. Lastly, I noticed that monogame has sort of a structure to it ( a separate function to load, draw, update, etc.) how does this impact development with it compared do other frameworks that don't have this, for better or for worse.

[hot hazel]

monogame just provides you with the basic abstractions so you don't have to worry about things like creating a window, interacting with graphics api (dx/opengl), etc

and provide some helpful helpers (math library code, model/textures/etc)

beyond that, it's all up to you

its not an engine

the load/draw/update/etc that it provides are optional

[quiet ibex]

@sage quest it impacts your development a lot or not at all, depends on how you use it. But it sounds like you don't know C# so if you read up on that, you'll start to figure out what really sets it apart from things like pygame

what's up LIBGDX FAN CLUB 😂

last week, there was the good ol' libgdx game jam that i know lots of you participated in.

cheers!

[vale zephyr]

soo, do i really need to use SpriteBatch for something like drawing solid color rectangles on the window/game

[digital dragon]

what else would you want to use?

or more to the point: why not use spritebatch?

[vale zephyr]

just based on what i saw in monogames documention, spritebatch is used for actual sprites, no?

[digital dragon]

well, it's for pretty much all things 2D

[vale zephyr]

oh

[digital dragon]

spritebatch abstracts the whole concept of drawing 2D graphics within a 3D renderer so you don't have to take care of texture positioning beyond a 2D plane

it is put together as a batch of graphics in order to have it only create one object to draw for the graphics card instead of creating a draw call for every single sprite

so you draw your 2D sprites / textures / text into a spritebatch (or multiple if necessary, iirc there is a call limit), the spritebatch then combines it for you into just one image and sends it to the graphics card

[vale zephyr]

yeah i got it

[hot hazel]

the alternative is to build quads (two triangles) and render those yourself

but thats basically what spritebatch is doing for you

[mighty herald]

Type parameter 'T' cannot be instantiated directly

anyone know what am i doing wrong?

[hot hazel]

: new()

After the class decl before {

[mighty herald]

?

[hot hazel]

Sorry, where T : new()

Google generic constraints c#

[mighty herald]

this is java D:

i had to do it for school D:

[amber pawn]

(sorry i just saw this, and this exchange is freaking funny as hell)

afaik there are generic constraints in java

[quiet ibex]

generics would be useless without constraints

[mighty herald]

:0

[hot hazel]

Less useful *

[amber pawn]

so the google keyword i'd use is "java generic array instantiate"
but honestly seeing the results point to reflection is discouraging

[mighty herald]

so rather than doing new T[][] i should pass in an existing array?

[amber pawn]

i think array is maybe not what you want to use in java for generic typed collections

[quiet ibex]

@hot hazel no you can't actually do anything without constraints, but typically you have a few implicit ones built into the language

@little moat thoughts on monogame for webgl?

[drifting sorrel]

Monogame for webgl is the reflection of a project that is a management disaster.
650+ bugs reported with none fixed during months, incredibly interesting PR with things like compute shaders or geometry shaders which are completely ignored by management, and one of the maintainers decides to incorporate a new platform which nobody asked for and for no real reason other that "look my lame 2d game runs in a browser with major bugs" with a technology already obsolete the moment they shipped it.

If I'm looking for a 2D rigidbody physics engine to use with monogame, what would you guys recommend? I've only really seen Farseer physics recommended for c# online but I've used that in the past and I remember having some issues with it so I'd prefer to use something different. Does anyone have suggestions? I think I'd prefer to use something written natively in C# rather than a port, but I'm still open to using a port as well. Thanks in advance!

[hot hazel]

What is the issue you were having?

[frigid fiber]

AetherPhysics is based on Farseer but has been improved quite a bit in the last years and it's still maintained (last version was released 9 days ago)

<@&133522354419662848>

[slate echo]

The first step is removing all Microsoft.Xna.Framework.XXX references and replacing them with references to MonoGame.Framework and MonoGame.Framework.Content.Pipeline. This is required as you will no longer be building against Microsoft XNA.

I'm getting a lot of build errors

[flat turret]

this is incorrect

You keep the references to Microsoft.Xna.Framework because that's the namespace Monogame uses to maintain backwards compat with games originally written in XNA

(for the record, FNA does the same technique)

MonoGame.Framework has a few extra tidbits that Monogame has added to the framework for additional functionality. It does not replace the Xna Framework namespace

Whatever guide/person told you to remove Xna Framework references is misled

[dusty drum]

Hi! does anyone have a link to learn about reading data from json or xml in monogame? I'm trying to read in some meta data for a sprite made in Piskel. I loaded the xml in the content pipeline but I cannot find any doc on how I would then use it

[hot hazel]

you can just read xml or json directly in c#

system.xml iirc and Newtonsoft.Json (or if you use modern c# system.text.json)

[frigid dagger]

@dusty drum ill show you how i serialize and deserialize object data with xml

first, your object cannot have a texture2d in it, texture2d cannot be serialized (i believe possibly color arrays can be but its usually not something that games do) you load your entire textures into content as usual
so you create a new class that contains the data that you want to save in xml, this class will not perform any actions it is only a base for your objects data, something like this

    public class EnemyData
    {
        public int enemyID;
        public int enemyHealth;
        public Vector2 enemySpawnPosition;
     }```
now at the top of your main class (or whichever class you build your enemies, etc) you need to include xml in your project
```using System.Xml;
   using System.Xml.Serialization;```

in your main/world class you build the serializer and the empty object

   EnemyData enemyData;```
initialise this serializer with the EnemyData class we built
```enemyXml = new XmlSerializer(typeof(EnemyData));```
so now you most likely dont have a file to read so we can write an xml file to your desktop, make sure you run this part only when you want to create a fresh file or save over a file
```                TextWriter writer = new StreamWriter(@"C:\Users\PC\Desktop\EnemyDataFile.xml");
                   enemyXml.Serialize(writer, enemyData);
                   writer.Close();```
this xml file will be plain text since we didnt encrypt it so you can now open the file as a notepad file and edit the int, vector2 or whatever other data you make your object have.
and now read the data from the file wherever you have it located into your enemyData that you declared
```TextReader reader = new StreamReader(@"C:\Users\PC\Desktop\EnemyDataFile.xml");
   enemyData = (EnemyData)enemyXml.Deserialize(reader);
   reader.Close();```
so basically if you now create a new class called enemyObject you can make it inherit all of the data that enemyData is holding
```enemy1 = new enemyObject(enemyData.enemyID, enemyData.enemyHealth);
   enemy2 = new enemyObject(enemyData.enemyID, enemyData.enemyHealth);```
but the real strength of serialization is by creating a list of data, so you could store many enemies, objects on the map, level editing data, inventory data, all read from and written to a single file the same way we read any data

@dusty drum if you want a bit of help on how to implement it in your specific use case let me know

[dusty drum]

ah great thank you so much @frigid dagger

[weak salmon]

talis thanked Melt

[dusty drum]

I do have a question regarding the content manager, you reference the xml by full path-- what if this was an android game? I'm new to monogame, but assumed that was the purpose of the content.mgcb file. I see it is able to build with the xml file, but I'm not sure how I would reference that in a stream reader

the use case is the sprite editor I am using, it can export meta data as a text file. like how many frames, dimensions for each frame etc. this way I can display the sprite from a sprite sheet the editor created

maybe there is a better way to do this though

[flat turret]

Many people ditch the content mgcb in favor of their own content loading system (as mgcb is... Pretty bad). You can add resources to your game via a data path and then reference them via relative paths

[frigid dagger]

@dusty drum so for reading the image data im not too sure what you load the json metadata into.

when i read my image data i make an image in piskelapp and export it as a spritesheet
and i read the image into my own data object which has image XY positions and number of frames and framesizes etc

so i read this notepad information and it spits out the positions of my content

and i can modify it at will on the image or in the data

[dusty drum]

are you manually creating that xml?

[frigid dagger]

i looked at the json metadata and it stores a lot of different fields in it
{"frames":{"New Piskel0.png":{"frame":{"x":0,"y":0,"w":64,"h":64},"rotated":false,"trimmed":false,"spriteSourceSize":{"x":0,"y":0,"w":64,"h":64},"sourceSize":{"w":64,"h":64}}},"meta":{"app":"https://github.com/piskelapp/piskel/","version":"1.0","image":"New Piskel.png","format":"RGBA8888","size":{"w":64,"h":64}}}
i suppose you would need to make an object that can store that data and then read it straight into your project

yea i just write the numbers into each field in the xml based on the image i create in piskel

its definitely not as streamlined as exporting the data from piskel and importing it back. but this way i get to just play with the data i want

[dusty drum]

ah okay, makes sense

[frigid dagger]

yea so i would suggest just finding what object you need to build in your project that can deserialize the data into

but its very worthwhile just making a simple object that stores coordinates and sizes of your images

[dusty drum]

Yea I like that approach, simple and effective

thanks again!

[frigid dagger]

and then for things like my map builder i launch a map builder project and import all my images then when i place one of them in the blank map i save its location to xml

and read that xml in the live game

so for placing maps you dont even need to open the raw data or change it manually

[dusty drum]

ah that's a good idea, yea ill have to build a little editor at some point

[frigid dagger]

yea good luck with your next mission, i was probably a bit vague about some things so i can clarify on something if you need but hopefully youre closer to a solution you want 🙂

How can I prevent monogame from rebuilding my assets each time I run the game ? Like he builds my font every time I run the game and it takes time ...

this is an example sketch i drew to illustrate what i will do in one dimension

same for the y

this is the code i wrote for this

ignoring the fact that this assumes that the textureregion uses bottom left point

this only shows this single texture in this spritesheet

                    }
                    nameIndex++
                }
            }
        }

    }```

ignore the comments

this is the code i currently have

lateinit var SheetAssets: MutableMap<String, MutableMap<String, TextureRegion>?>

outside the Assets object

this function is within the assets object btw

so to summary

how do i parse standalone textures from a spritesheet

[crimson yacht]

like the algortihm of it

[crimson yacht]

help

[silk oracle]

Are you just trying to split the sprite sheet so you can extract specific images?

TextureRegion has a static method called split(tileWidth, tileHeight)

TextureRegion.split(int tileWidth, int tileHeight)

it's a 2D array

If you're trying to split the sprite sheet and then assign things names, you can use the GDX Texture Packer -> https://github.com/crashinvaders/gdx-texture-packer-gui/releases

@crimson yacht

[crimson yacht]

the problem is that there can be a bit of distance between textures ( absolutely not for between textures and borders thought)

[silk oracle]

so, you're wanting to assign each texture a specific location you can pull from?

because some have different padding between?

[crimson yacht]

i've thought of using an atlas but i deemed that it is too difficult for me to integrate it into my project as

1. dont know java
2. they are in different directories

[crimson yacht]

what?

https://cdn.discordapp.com/attachments/896777885178802226/896777904585863248/unknown.png

[silk oracle]

So, you have a sprite sheet with images that all have different lengths between them, right?

[crimson yacht]

something like this

[crimson yacht]

yes

https://cdn.discordapp.com/attachments/896777885178802226/896778254386597908/unknown.png

like this has a padding of 0

[silk oracle]

Looks like all of those GUI elements have more than a padding of 0

are you using LibGDX?

[crimson yacht]

yes

[crimson yacht]

black bars are borders

but still, a good candidate for applying padding

[silk oracle]

GUIPack.png
size: 647, 558
format: RGBA8888
filter: Nearest, Nearest
repeat: none
Empty Button
  rotate: false
  xy: 0, 0
  size: 8, 8
  orig: 8, 8
  offset: 0, 0
  index: -1
Play Button
  rotate: false
  xy: 8, 8
  size: 8, 8
  orig: 8, 8
  offset: 0, 0
  index: -1

^ That's what an atlas pack looks like, so you can assign each image a location and name

The xy: is the location, the size is obviously the size in pixels

[crimson yacht]

i know how atlases work

but

i thought i couldnt implement atlases for this

as it is an atlas itself

arent atlases for combining hundreds of textures into one big one?

[silk oracle]

It can be, yes

Or, you can take one texture and split it into multiple using the atlas file and loading it as such

In case all of your images are already on one image

[crimson yacht]

but

the file im using as a spritesheet is literally just a png file

[silk oracle]

I understand

Just treat it as if it's a packed texture

A Texture pack is literally just an image packed with other images, therefore being ONE image

I promise it's that simple

[crimson yacht]

thats what im trying to do

im trying to get standalone textures and store them in a way i can retrieve as such:

SheetAssets[SpriteSheetName]!!["MenuButton"] : TextureRegion

[hot hazel]

Sprite { File; Region }
Object { Sprite foo; blah ; }

[silk oracle]

Exactly what a TextureAtlas does.

Try doing this:

Create a TestPack.atlas file with the PNG file in the same folder. Add the png file name to the top of the atlas and a test for the menu button to it like so:

Test.png
size: 647, 558
format: RGBA8888
filter: Nearest, Nearest
repeat: none
Menu Button
  rotate: false
  xy: 0, 0
  size: 8, 8
  orig: 8, 8
  offset: 0, 0
  index: -1

Load the texture atlas, find the region called "Menu Button", and see how that works?

You now have a texture in your sprite sheet called menu button when you load it up from the PNG file

[crimson yacht]

how do i name the regions?

i guess thats what i tried doing from the beginning

so it supports parsing classical spritesheets

great

[silk oracle]

If you look at the code I provided, you'll see under the repeat row, that there is a Menu Button text. That's the name of the region, and every time you create a new region, you need to add the tabbed spacing underneath it to provide the rotate, size, offset, etc.

The xy: 0, 0 variable is the location to cut from the image and the size:, 8, 8 is the size in pixels of the image to cut

I assume you're writing this in Kotlin?

[crimson yacht]

ohh

i need to do it manually?

damn

that was the reason why i tried to build a spritesheet parser

[silk oracle]

textureAtlas.addRegion("name_here"); works

atlas.addRegion(name, texture, x, y, width, height)

If you don't want to use a file

[crimson yacht]

ooh

this is absolutely what im trying to do, thanks

wait

how do i get the texture from it?

i already try to get texture with the parser

[silk oracle]

TextureRegion(Texture texture, int x, int y, int width, int height)

set the x, y, width, and height of the texture you're taking from

[crimson yacht]

aand we have looped back to the beginning

[silk oracle]

Texture menuButton = new Texture("TestImage.PNG", 0, 0, 8, 8)

textureAtlas.addRegion("Menu Button", menuButton, 0, 0, 8, 8);

[crimson yacht]

that atlas method is just a method to retrieve the single textures

the problem is automatically assigning it

i think i made an off brand texture atlas already

[crimson yacht]

the problem is that there are 144 textures

[silk oracle]

How do you mean automatically? Don't you have to assign them a specific name any way? Like "Play Button", "Menu Button", "Exit Button", etc?

[crimson yacht]

i have a linear list for it

if i set it to null it is set to index number

sec ill send an illustration

https://cdn.discordapp.com/attachments/896777885178802226/896814479487143986/unknown.png

[silk oracle]

Dang man. I would really just suggest the atlas regions because it's cleaner and you don't have to write all that code for it

[crimson yacht]

there are 144 textures :/

[silk oracle]

<.<

[crimson yacht]

so anyone can help?

[crimson yacht]

if u are willing to help please read this:

[hot hazel]

write a file format that encapsulates the info you want

also id say you're doing it backwards

rather than creating 'regions' in an atlast

everthing you want has a 'sprite' that defines the region of what image

[crimson yacht]

i already have the wrapper or encapsulator

as a mutablemap<string, mutablemap<string, textureregion>>

[crimson yacht]

how

@hot hazel ?

[hot hazel]

Yeah wrong direction

[crimson yacht]

wrong in what direction

can u elaborate?

[hot hazel]

I already explained

Don't make a dictionary of names to regions

[crimson yacht]

ok that is the easy part to fix

but the main problem is that i need to find an algorithm

[hot hazel]

For?

[crimson yacht]

get specific textures from a png with each texture having width, height, posx, posy variables

with offset in between textures

    fun loadSheetAtlas(directoryToSheet: String, names: List<String?>?, width: Int, height: Int, spaceBetweenX: Int, spaceBetweenY: Int, spritesX: Int, spritesY: Int)
    ```

https://cdn.discordapp.com/attachments/896777885178802226/896777904585863248/unknown.png

an example sketch

[hot hazel]

Use a grid or a bin packing Algo

Then store the regions in a file

[crimson yacht]

there is distance between the textures tho

[hot hazel]

So

Store the regions in a file

[crimson yacht]

how do i generate the "regions"

that is the main problem

parse, i meant

[hot hazel]

Json,csv

Standard file parsing

Look at Sprite font generators and their output

[crimson yacht]

that might be what im looking for

does it support distance between textures?

wait

arent sprite font's a bit too "official" and unsuited for game use?

[hot hazel]

@crimson yacht is this what you want? https://www.codeandweb.com/texturepacker

[final kestrel]

Bit of an odd request, I'm in need of a sprite font .xnb containing as many unicode characters as possible. I'm building "Arial Unicode MS" right now but its taking a while via the MGCB, wondered if anyone had one already built they could share to save me the few days time it'll take to build 65k glyphs

[crimson yacht]

i already have the sheets

[hot hazel]

I would build them into multiple sheets probably, or you may just want to find a vector font renderer and bundle an actual font

[final kestrel]

I have a ttf, It's a little weird of a situation where Im modding an existing MonoGame application and need to load my own SpriteFont to support as much potential user input as possible, without knowing the language theyre gonna use beforehand. I'm currently building the ttf->sprite font->xnb, how would you suggest going about multiple sheets? It's been a while since I've touched MonoGame proper

[hot hazel]

diy

dont use the monogame spritefont system

but honestly id find a TTF renderer

[final kestrel]

Right, not a bad shout, I'm using some of the helper functions for displaying text in the original game I'm modding atm so would require writing my own systems for that - which is doable for sure, the code isn't complex. I may go down that route instead - thanks!

[hot hazel]

but either way i guess

use code pages

they're like 4096 characters a page i think

and one sprite font per code page

then swap em out

[final kestrel]

Code pages? I'm afraid Im not too familiar with font formats and the like prior to this

[hot hazel]

its a legacy windows thing

you'd just be emulating/recreating it yourself in code

the spritefont system has support for sparse fonts, but its going to put every character in one sheet I think, which i dont think is what you want

[crimson yacht]

i think i asked the wrong question at the first place

is there a spritesheet parser library or app

[hot hazel]

im sure someone who built a packer has written one

it will probably just be as quick to write your own

it has to do with the audio, it works fine with no devices but when i plug one in

it crashes

yeah i am not really going to be able to help you much without debugging the program

question

say i have a function called fromPixelScalingToGameScaling

where i do a few multiplication and division calculations inside it

say that i'm calling it 1000 times every frame

would it slow down the program by a considerable amount?

or say like i have this function

fun returnSameObject(number: Int) : Int {return number}

how slower is it than directly passing the object?

[turbid grove]

Managed to set up a Monogame+Nez project on VS code, the next few weeks are going to be interesting! 😄

[toxic wigeon]

late to the party but you should check out LeoECS. It is awesome, lightweight and easy to extend

[turbid grove]

Regarding Monogame, should I be drawing everything from the main class? I managed to represent a chunk of perlin noise in colors, but when I began to detach the project into separate files, I found myself lost on how to handle drawing in general.

[flat turret]

So you've got your Draw method, where you have access to your spritebatch

What you can do is you can add a "Draw" method to your other classes and provide them with the spritebatch, which they can draw themselves into

that way you can do something like

_spriteBatch.Start(); // or whatever the API is,  can't remember
foreach(MyClass obj in sceneObjects)
{
  obj.Draw(_spriteBatch);
}
_spriteBatch.End();  // or equivalent

I believe Nez has a thing to handle this for you?

You add the Nez object to the scene and it draws itself, or something (I've never actually used Nez, however if you want I can DM you the link to the monogame discord where the nez developer is very active)

[raw warren]

Movement :: Monogame

that's what ik lol

[turbid grove]

Yeah, sounds like what I need. I found the discord as well, I'm glad it's so active 😄

[quiet ibex]

microsoft has some good c# getting started tutorials that could help you understand parameters, references and types

[turbid grove]

Indeed, however I'm porting an existing project from Unity, I'd like to think I already know the basics, just have to get used to the fact that it's a bit more low-level 👍

[quiet ibex]

when you're using unity, you typically only utilize a tiny subset of the c# language. so when you do other things, there's a huge gap to fill

[mortal tendon]

Hey guys, I need some help with tilemap. I find a lot of information on how to load tmx files. but I need to load XML. Could anyone help with it ?

[digital dragon]

Pretty sure tmx is xml based

[mortal tendon]

Yeah I've read about it

[digital dragon]

if you are working in c# you should be able to implement your own parser using the XmlReader from System.XML

if you are in java land I am the wrong guy^^

also if you don't want to re-invent the wheel, there definitely are a bunch of oss parsers for tmx that you could modify. There might be something in monogame extended as well

[mortal tendon]

Uff, okay. I just thought it would be easier because we can load the tmx with one command and I thought there is something for the xml. I just don't understand why did the game studio give me a map in the format xlm instead tmx

[digital dragon]

you might want to check the actual structure of the file. Maybe it's a tmx file with just an xml file extension?

otherwise it might be easier to write a conversion tool that takes their xml and outputs tmx if you already have an importer for that

(or maybe they just sent a wrong export by accident?)

[mortal tendon]

I've just looked at tmx format and looked at this, doesn't look like tmx

[digital dragon]

did they supply any documentation for their format?

if they just handed you an xml without any description of how it's set up then that's not really useable

[quiet ibex]

tmx is not your average xml though, so it'll take some work to make it usable

i made a library for dealing with it a while back https://github.com/Ragath/TiledLib.Net might need to be updated to handle the latest Tiled features, but it should handle the vast majority of them

[sonic basin]

Wait people still use that engine?

[grave fable]

is there a way to draw a sprite with no texture (just a solid color), and to add the texture later? in monogame

[lament gyro]

I don't think its possible with the standard sprite batch... writing a shader should be the best way.
Tbh I think the question is kind of strange. What are you trying to achieve?

[grave fable]

I don't have textures right now, so I want to use a solid color as a placeholder.
actually, I think I've found a solution.

        private Texture2D SolidColorTexture(int sizeX, int sizeY, Color color)
        {
            Texture2D texture = new Texture2D(GraphicsDevice, sizeX, sizeY);
            Color[] data = new Color[sizeX * sizeY];
            for (int i = 0; i < data.Length; i++) data[i] = color;
            texture.SetData(data);
            return texture;
        }

[lament gyro]

Or you could have just loaded a placeholder texture... But what you asked for was something completely different.

[toxic wigeon]

This is not what you want to do. You want to create a 1x1 pixel texture in white and only create it once. You use the Draw overload which accepts scale and color to paint and draw it the necessary size. Everything else is wasteful

why are my usings broken? there is a red squiggly line under Microsoft.Xna

[quiet ibex]

you always have an error message associated with the squigglies that explain what's wrong

[grave fable]

yea, it seems like it doesn't find the packages

but I don't know why

[quiet ibex]

probably haven't run nuget restore

[grave fable]

how do I do that?

[quiet ibex]

normally it happens automatically when you build. But if you've turned it off, then right-click the solution and pick restore

[grave fable]

its on. I tried to run it manually, but nothing changed

[quiet ibex]

check the output log for errors then

[grave fable]

All packages are already installed and there is nothing to restore.

[quiet ibex]

then you're missing packages

[grave fable]

My project has the following packages:

MonoGame.Content.Builder.Task
MonoGame.Framework.DesktopGL
MonoGame.Extended.Tiled

[quiet ibex]

and are those the right packages and on the right project?

[grave fable]

I believe so. the first two are the default packages, if I am not mistaken

and I am getting errors on ```
Microsoft.Xna.Framework
Microsoft.Xna.Framework.Graphics
Microsoft.Xna.Framework.Input
MonoGame.Extended.Tiled
MonoGame.Extended.Tiled.Renderers

basically all the namespaces I try to use.

[quiet ibex]

you've probably got a mismatch between the target framework and the monogame package then

[grave fable]

wdym?

whats the "target framework"?

[quiet ibex]

either way, your build output still tells you whats failing

probably .net6.0 in your case

which does not play nice with monogame yet

[grave fable]

can I use an older framework?

[quiet ibex]

yes

[grave fable]

how do I do that?

[quiet ibex]

edit the project

[grave fable]

the .csproj?

(on VS 2019)

[quiet ibex]

yes, but you should switch to vs2022

Last time I checked the MonoGame VS plugin wasn't avaliable for VS 2022. not sure if its necessary tho.

I just looked and my TargetFramework is netcoreapp3.1. not sure if its what its supposed to be.

[hot hazel]

tis not necessary

TargetFramework can be set to "net6.0" i think

[quiet ibex]

it can, but it wont work if you do

since monogame is broken on .net6

I had a couple of hours to kill and made a small game

[final herald]

wow the snake drawing mechanic is really good, must hv taken a lot of thinking eh

[toxic wigeon]

I think I made the whole game in like 16 hours where like 8 hours of them were learning the physics and making them feel the way I wanted

drawing was probably around an hour or two

[final herald]

oh

I am working with LibGDX. I want to set the background of a Label such that it resizes with the size of the Label. For that I am using an image which has a size lesser than the Label. However, due to resizing, the result is like this - (refer to the second attached image). So I made the image larger than the Label. However, it doesn't resize like that - (refer to the first attached image). any solutions?

[toxic wigeon]

Basicall what you need to create is a 9slice. The center piece can then easily be filled with anything else

[final herald]

oh i see, thanks

I need webgl shader code to draw image outline.. Any one can help me?

[toxic wigeon]

If i google some of these words i get good hits on google

It is better to state the explicit problem you have and what you have tried. People will be mode inclined to help

[quiet ibex]

if you're asking someone to do it for you, that's not gonna happen. If you have a problem with your implementation, someone might be able to tell you what it is

[rain compass]

where to start

any links?

[quiet ibex]

tried a google search?

[rain compass]

no res found

[quiet ibex]

https://stackoverflow.com/questions/12924188/outline-effects-in-opengl

i just googled "shader image outline"

[rain compass]

that not work

i can show trillion of such things

[quiet ibex]

either you're following the instructions wrong, or you're phrasing the problem wrong. In which case you need to read up on the subject and learn the right terminology

if its the former, read up on shaders in general

[hot hazel]

there's a number of ways to do an outline

they can get pretty complex

[rain compass]

@hot hazelu know easy one

Hello guys i want to step in game development and decided to make 2.5d indie games on java language so what path should i follow

[toxic wigeon]

hard question with no real answer

what do you know?

[nimble rose]

Well i am in intermiadiate level of java programming and i want to make games with libgdx so is there any tutorials on how to make games with libgdx

[toxic wigeon]

Seee, this results in a completely different question. No need to feed you beginner stuff.

you might want to check out this https://happycoding.io/tutorials/libgdx/

and since there are many parralels you could also check out MonoGame but that one is C#

[final herald]

i started gamedev in the sae situation i followed the libgdx flappy bird tutorial of a guy named brent aureli. he also has another series in which is he shows how to create mario in libgdx. he makes really good tutorials if u ask me

Hello, I am trying to create 2D game. I want player to be able to go behind a tree or in front. What is the best way to achieve that? I tried using several layers with Tiled map editor (Will attach images), but that did not went as planed. Searched google, but not found any useful information.

https://cdn.discordapp.com/attachments/958450460711354458/958450550838558810/unknown.png

[hot hazel]

you need some kind of front to back ordering, likely just the y value of the bottom pixel

[placid gate]

Yeah, but libgdx does not have any of that

[toxic wigeon]

then you order them yourself... whichever you draw last is on top

[hot hazel]

make a Draw() call that puts everything into the list, sort by y, then pass that to the actual draw code

[toxic wigeon]

^this is specific to the game and also depends on stuff like layers or pivots of sprites

[placid gate]

With help of other person I manage to pull that of with tinkering rendering and shaders

[toxic wigeon]

what are you trying to tell us?

[placid gate]

That I solved my issue

[toxic wigeon]

If you have questions and found a solution you should share your solution with others for you aren't the only one who will have that problem

and drop a little thanks for people that put in the effort to answer your specific question which might be easily googleable so you don't have to

[final herald]

ok so i have a weird problem with libgdx. i tried googling it in many different ways but i cant seem to find an answer
ok so i have a sprite. i am rendering it to the center of the camera (camera is at (0,0), so i render the sprite to (0,0)). it gets rendered to the center of the camera. perfect.
however, now i have to do the PPM conversion. i scale down the size of the viewport and my sprite and render it to the center of the camera (0,0). however, this time, the sprite gets rendered elsewhere, even though its coordinates are still (0,0) according to libgdx. below are some images - (first attachment is PPM = 1 ie no PPM conversion yet, second is PPM = 10)

i have no idea why this is happening

if anyone wants i can send the project root folder here so that they can see exactly what is going on

[final herald]

this issue is solved, it was a problem with the sprite's origin and rotation.
apparently you have to call sprite.setOrigin() again after setting the size to make sure the origin stays where you want it to relative to the sprite's position

[bright hazel]

guys do you make your own tile map system in monogame? or you just use monogame extended

i was trying to make one using for loops running each frame and my rtx was at 50% usage

[hot hazel]

I made my own

only render what you can see

and if you really want to cut down on CPU usage, render one quad and calculate tiles in a shader

Noice=nice

Cause

I m

Gud

Guy

[hot hazel]

so?

anyway i need to sleep

[flat meteor]

Why it's 2:46 pm

[hot hazel]

its 2am here

[flat meteor]

Ohh

Okk

But can u give one

❓❔❓❔❓

@hot hazel tell

[bright hazel]

how do you guys do anti aliasing

?

monogame

[hot hazel]

GraphicsDeviceManager (usually called from your game's constructor) has a PreferMultisampling

alternatively you could write an fxaa/similar post process shader

[bright hazel]

Thanks

How can i use json? I want to make level for example...(monogame)

Like json files

[hot hazel]

depending on your .net version you have you might have System.Text.Json but more likely you can add Newtonsoft.Json from NuGet

[bright hazel]

Ok

Thanks

And

[hot hazel]

from there its up to you how to map data to a level

[bright hazel]

How do you do levels?

[hot hazel]

thats very much up to your game

[bright hazel]

So there isn't any editor

[hot hazel]

i mean there are editors yes but every game is different

monogame is not an engine

[bright hazel]

So its better to use something like json/xml

[hot hazel]

not sure what you mean

[bright hazel]

Like you make levels you make them in json right?

[hot hazel]

json is a data format

you could write it by hand but that would suck

[bright hazel]

Yeah

But what do you use

[hot hazel]

i wrote my own stuff

what kind of game are you trying to make?

[bright hazel]

Just having fun. i was wondering how celeste made their levels

*fun

[hot hazel]

you could probably use a tool like Tiled

theres a library called Monogame.Extended that I think has a parser for tiled's tmx files

[bright hazel]

Ok thanks

[bright hazel]

how can i fix this error?
The source file '/Documents/MonogameProjects/Project2/Project2/Content/../testing.tsx' does not exist! Documents\MonogameProjects\Project2\Project2\Content\mapTestUwU.tmx 1

[bright hazel]

Why does this json content reader doesnt work?

using System;
using System.Collections.Generic;
using System.IO;

using Microsoft.Xna.Framework.Content.Pipeline;
using Microsoft.Xna.Framework.Content.Pipeline.Serialization.Compiler;

using Newtonsoft.Json;

    public class JsonImporter : ContentImporter<Dictionary<string, dynamic>>
    {

        public override Dictionary<string, dynamic> Import(string filename, ContentImporterContext context)
        {
            context.Logger.LogMessage("Importing JSON file: {0}", filename);

            using (var streamReader = new StreamReader(filename))
            {
                JsonSerializer serializer = new JsonSerializer();
                return (Dictionary<string, dynamic>)serializer.Deserialize(streamReader, typeof(Dictionary<string, dynamic>));
            }
        }

    }

}

    [ContentProcessor]
    public class JsonProcessor : ContentProcessor<Dictionary<string, dynamic>, Dictionary<string, dynamic>>

        public override Dictionary<string, dynamic> Process(Dictionary<string, dynamic> input, ContentProcessorContext context)
        {
            context.Logger.LogMessage("Processing JSON");

            return input;
        }
    }
}

        }

        public override string GetRuntimeType(TargetPlatform targetPlatform)
        {
            return typeof(Dictionary<string, dynamic>).AssemblyQualifiedName;
        }

        {
            return "JsonExtension.JsonReader";
        }
    }
}

[quiet ibex]

@bright hazel its not that simple to make a hierarchial writer

and you'd be better off sending the json to a processor that converts it to a game-specific format and use that

no custom reader/writers needed then

[bright hazel]

ok

[bright hazel]

so how are you loading json files?

[bright hazel]

or do i even need to load them

coudnt i just put them in content folder and access them through path

[bright hazel]

can anyone help me understand matrix?

[bright hazel]

[quiet ibex]

you shouldn't, you should be processing your content at build time instead of runtime

that's the whole purpose of the content pipeline

[bright hazel]

oh ok

[hot hazel]

meh, i am not a fan of the content pipeline

esp when debugging

[quiet ibex]

debugs the same way as all other build tools

[hot hazel]

i mean content debugging not build tool debugging
