If you want ¯_(ツ)_/¯

[brisk yew]

If you wish, but I'd suggest you use pygame-ce then
that's pip install pygame-ce contrary to what most tutorials use which is pip install pygame
although there are new tutorials coming out, some by prominent people in the field that also use pygame-ce
What's pygame-ce?
pygame-ce is better: better maintained, new features, more optimizations, new governance model, core contributors of pygame have moved over to it
Here's the initial announcement on reddit: https://www.reddit.com/r/pygame/comments/1112q10/pygame_community_edition_announcement/
You can follow the latest updates starting from here in the pygame community discord server: #772506385304649738 message
Or of course the GitHub releases: https://github.com/pygame-community/pygame-ce/releases
Docs: https://pyga.me/docs/
Manually kept API differences (might not be up to date): https://gist.github.com/davidpendergast/77e49f8028ce611ac478c38f77f9f72f
Installation (safe method):

pip uninstall pygame
pip install pygame-ce

[pearl linden]

Ok I will do

Cool ad btw

[brisk yew]

even though most tutorials still use pygame, that is not to say that they are useless, pygame-ce is rather cross-compatible with it, especially the older version since backwards compatibility is still maintained
this is about the newest tutorial out there if you wish to get started: https://www.youtube.com/watch?v=2gABYM5M0ww (haven't seen it in its entirety so can't exactly vouch for it's quality myself more than he's a trusted source on pygame tutorials in general, but it should be good enough to get you started)

[pearl linden]

Ok thanks

[pine plinth]

You are so funny. Why are you posting info about pygame-ce after every mention of pygame? Is this so necessary?

Childish behaviour of pygame-ce members is the only thing that stops me from moving to pygame-ce

[knotty hamlet]

You didn’t seem to mind when several pygame-ce devs, including Matt here, were helping you compile from source as part of your NoGIL experiment. 🙂

That being said, we really need a good about page so we could just link that and leave it at that.

[tender scaffold]

is anyone able to help me with a pygame question?

[vernal kite]

i can try and help depending on what it is, as i am still lerning it my self

[tender scaffold]

i am making a scrolling 2d platformer level, and I want the level to stop scrolling whenever the end of the level is visible. do you know how I can do this? ive already tried to make the scroll variable and the speed variable 0 but thats not working.

[vernal kite]

maybe have a rectangle made at the end of the level, and when the camara is to colide with it, then have it stop, or not able to go beyond it
this idea is maid with me thinking that character or moving object of the platformer, is not able to move beyond the camara, or map

[tender scaffold]

i havent worked on the collision aspect of this game yet, atm i just have the level and movement mapped out. I also don't know how to code a camera I kinda just played with the movement and scroll values till it sorta made sense. do you think this is an issue that I need to tackle later once I finish the collision and spawn the enemies?

[vernal kite]

yes i do think that it is somthing that might bee needed to be look on at a later point, because, as i read it, you were gaving problems with the camara moving beyound the bodories that you might have set for it (if you are to give them any), but what you are talking about seams to be (well i cant realy say) a canvis in a void, but you have yet to frame the picture, so you are still able to draw into nothingness

[tender scaffold]

I could always just delete the backwords scroll mechanic so once I hit the end i dont have the option of going back

i think thats how mario i coded

[vernal kite]

yeah i do think that is how the first mrio games worked

now onward to my question, as i have been looking into formationg of text with pygames rendering function, and fell over this line

If you render '\n' an unknown char will be rendered. Usually a rectangle. Instead you need to handle newlines yourself.

so i wish to ask if any one knows "how i do handle the newlines myself"

[dense mica]

Hello, Can you help me for decryption this. (AES)

[dense mica]

@vernal kite Yes, it works. Game files are encrypted with Zstd and AES. But now I can only Zstd.

[vernal kite]

that does not tell me much of how to decypte it, as i was thinking it was more akin to a cesar code

[dense mica]

cuz, i see this. so I think it's AES. (https://github.com/kourain/AOV-Tool/blob/main/aov_zstdv3.1code.py)

[vernal kite]

arr, well i have no idea of what that is, so i do not realy think that i can help

do you by any chacne know how to format text in pygames,

[dense mica]

sorry, no

[knotty hamlet]

"Format text" means what?

[vernal kite]

well currently the out but i get is this (image one)

and i wish for it to look like so (image two)
that is what i mean with formatting, i do know it is not quiet the right word, but hard to find one beyond placement, witch can mean so many other things

[knotty hamlet]

How are you rendering your text?

[vernal kite]

currently i am using render.

[knotty hamlet]

pygame_testing_area.character_name() returns that string?

[vernal kite]

yes

it is the file and the functon

[knotty hamlet]

I would expect a function called character name to return a character name

Just checking

Instead of this prompt thing

So you join text_1 into a big string and render it

Because you have it as a list of strings

[vernal kite]

come again

[knotty hamlet]

Your text starts in text_1

it's a list of strings

[vernal kite]

indeed

[knotty hamlet]

So you make it into a single string

And then you render that

Where do you join it into a single string?

[vernal kite]

oh i see,

here,

[knotty hamlet]

Really?

[vernal kite]

yes

[knotty hamlet]

I always thought newlines rendered as boxes in pygame

Must depend on the font I guess

[vernal kite]

it is default font as you can see in image 3

[knotty hamlet]

Anyways, one solution to your problem is to switch to pygame-ce. It's a drop in replacement for pygame, not even the import needs to change. But it does support \n in font rendering, unlike stock pygame.

pip uninstall pygame && pip install pygame-ce

Try that

[vernal kite]

cant realy get that to work, seams to have forggotn how to use pip

[knotty hamlet]

What's the problem?

[vernal kite]

i do not know how to use what you send

[knotty hamlet]

Run it in the command line

[vernal kite]

i do not know why, but i do not know what that is

[knotty hamlet]

Are you on Windows?

[vernal kite]

yes, so just cmd

[knotty hamlet]

Yeah

[vernal kite]

'pip' is not recognized as an internal or external command,
operable program or batch file.

[knotty hamlet]

How are you running your code?

[vernal kite]

what code, i am just placing it dicratly into cmd

[knotty hamlet]

I'm talking about your code, not the command I'm suggesting you run

[vernal kite]

i am not running any code

[knotty hamlet]

You're rendering text in pygame

I don't see how you could do that without code 😄

[vernal kite]

yes but have jet to do anything with pip uninstall pygame & pip install pygame-ce

[knotty hamlet]

Since you don't know how to use pip, I need to summon the knowledge of how your environment actually works

How you've been running your code is a big part of that

I guess I could just give you a random guess on how to use your pip

python -m pip

[vernal kite]

no i have used pip before, i have just forgotten it

[knotty hamlet]

Yes, therefore you do not currently know how to use pip

[vernal kite]

indeeed, that is how i think forgetting works

[knotty hamlet]

python -m pip uninstall pygame && python -m pip install pygame-ce

[vernal kite]

so yeah i am just gettign errors on all the text that is copied in

[knotty hamlet]

Because you didn't put it cmd

[vernal kite]

arrr

so yeah it does not seam to be able to find python in cmd

C:\Users\ckrjo>python -m pip uninstall pygame
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.

C:\Users\ckrjo>python -m pip install pygame-ce
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.

[knotty hamlet]

python3 -m pip uninstall pygame && python3 -m pip install pygame-ce

[vernal kite]

no was not found either

and yes it is version 3 that i am having

[knotty hamlet]

Yeah, so how are you running your code

You didn't answer

[vernal kite]

in pycharm mostly

[knotty hamlet]

I was gonna say earlier...

If you're pycharm none of this will work

Because pycharm doesn't use a system python environment, it has its own environment

This is why I asked

[vernal kite]

yeah i just did not quiet get what you meant with, "how i run python" but now i do know

[knotty hamlet]

In pycharm, you should use their special thing: https://www.jetbrains.com/help/pycharm/installing-uninstalling-and-upgrading-packages.html

If you uninstall pygame and install pygame-ce, your text will render with newlines

[vernal kite]

and is this where i am to tell you that i did at some point install pycharm with out that

[knotty hamlet]

You could probably use pip in the pycharm shell

Because that would be within the virtual environment

[vernal kite]

okay, i have a idea of what that means

sooo @knotty hamlet i am just to delete the pygames file form my exspoles manuely, and then get the ce files somewhere,

[knotty hamlet]

What?

[brisk yew]

PyCharm you say

super simple actually

[vernal kite]

well i am not to give up on a function that i do wish to get, jsut beacuse all we have done with in 1 program does not work, so is kind of asking if this is a option

[brisk yew]

you go to the Terminal (in PyCharm obvs)
and type these commands

cmd
venv\scripts\activate
pip uninstall pygame
pip install pygame-ce

[vernal kite]

terminal in PyCharm ?

[brisk yew]

apparently alt + f12 opens that

but you should be able to see it some place bottom with the other tabs

or like double click shift and then type terminal to find it

[vernal kite]

found it

[brisk yew]

python -m pip then

[vernal kite]

same message as in cmd

py -m pip, did somthing

[brisk yew]

alr, well, then venv\scripts\python -m pip

[vernal kite]

py -m pip, did somthing

[knotty hamlet]

Your environment only has python as py 😢

[vernal kite]

apparently

[knotty hamlet]

py -m pip uninstall pygame && py -m pip install pygame-ce

[vernal kite]

yes is uninstalling pygame\s now

so it seams that apparntly, by uninstalling pygames, it did also remove all pycharms things

[knotty hamlet]

Run py -m pip install pygame-ce

Speculation: MadMan4290 actually means linter is freaking out because it can't see pygame

[vernal kite]

no i mean, that when it was done uninstalling pygames, all other folders that was on my desktop form pycharm, was also removed

[knotty hamlet]

I don't see how that's possible

Did you run the second command?

[vernal kite]

okay no worries, it removed the shortcuts that was on the desktop, not the filles that was in the system, witch to me is odd

but found al my filles again

[brisk yew]

great, does PyCharm still yell at you about stuff missing?

[vernal kite]

yes, have to geet all the chaces, and patches, and packes back

[brisk yew]

does the code run?

[vernal kite]

nope, it seams that i am currently missing PIL

[brisk yew]

and it wasn't missing prior?

[vernal kite]

no it was not, but it seams that py -m pygames, did uninstall pycharm, as i needed to acturely install it back again, but the fills of mine was still around

[brisk yew]

that's more unlikely than winning a lottery, wanna hop in a vc rq?

[vernal kite]

but everything seams to be back now

[vernal kite]

Hello what does it actually imply to make a (2d) game multiplayer using pygame. Generally talking about needed knowledge, libraries and such things? Is it better to add multiplayer to the game after it is already developed or is it better to add it from the beginning?

[oak flint]

Mid or after seems best imo

this is just an opinion though

Although if you head to the pygame server there's a guy making a really nice game isometria and he's implemented it mid development

If youd like you can probably talk to him

no, i don't let you

[pearl linden]

whta

what

[untold ginkgo]

You can do anything you want

Depending on amount of C libraries written for this 😄

[proper peak]

you could use an opengl wrapper like pyglet and get, uh, the authentic experience of developing a 3d game with only opengl 😛

(but there's also actual higher-level 3d libraries like panda3d or that other one)

            coords = (tile['pos'][0] * self.tileSize, tile['pos'][1] * self.tileSize)

            screen.SCREEN.blit(self.assets[tile['type']][tile['variant']], coords)

doesn't run
but!

runs !

like if I do the above, the tiles don't show, and I have absolutely no idea why, there's no error thrown either

I was thinking maybe they're too high up but I can't get them to show up

im trying to make a top down game without using pygame could anyone help me with getting the screen to follow the player based on key events to simulate a camera

[brisk yew]

have you tried printing out tile["pos"]?

[pallid patio]

Yeah I ended up making a thread for it, the values wrre just way too large (201*16 is definitely off the screen turns out)

[dawn quiver]

hi!
what do you think about using a macbook pro (m2) for 3D modelling and ui/ux design or animation stuff?
I'm specifically talking about the apple silicon- how would you compare it to the mid range windows laptops performance wise- is it better or worse?
love to know someone's opinion who's well acquianted with this stuff. thanks

[dire delta]

I don't have firsthand experience with it, but Linus Tech Tips did a performance benchmark for various tasks and it seemed underwhelming compared to anything with a 4080.

[dawn quiver]

oh my :(. that’s not good

[dire delta]

https://www.youtube.com/watch?v=buLyy7x2dcQ

It's not specifically about macbook pro, but the price vs performance comparison holds true

[dawn quiver]

will definitely check this out ! thankyou💗

[pseudo zenith]

I apologize if this is a basic question, but does anyone know of a tutorial to get pygame working on a site like itch.io. In other words, being able to be played online? Thanks!

[dawn quiver]

@pseudo zenith - If you mean a web build of a Python game made with pygame, I suggest looking at this module: pygbag (https://github.com/pygame-web/pygbag)

[pseudo zenith]

That’s what I meant. Thank you!

Profile your code
first you'd want to install snakeviz for displaying the profile output

pip install snakeviz

then do the profiling (in terminal (cmd))

python -m cProfile -o out.prof main.py

play around for a bit, exit the game then display the output using snakeviz

snakeviz out.prof

Alternatively you can

pip install ez-profile

add

import ez_profile

to your main file at the very top, then run your game as usual, play around for a bit, exit and done

Both ways in the end a browser tab would open with a neat output of the profiled stuff

but from what I can see, you're just making it do too much...

[brisk yew]

also if you're just setting pixels on the screen, drawing circles is probably not the optimal way to do so, you could use pygame.surfarray to get access to surfaces as arrays and then just use numpy to set the pixel values in the necessary locations

because from what I can see, you're drawing about 10k points?

[vast chasm]

yeah

[brisk yew]

yeah, calling pygame.draw.anything is probably gonna impact performance a lot if you do it 10k times alone

[vast chasm]

tbh im kinda emberrassed to see how many calls i make in my program

[brisk yew]

although I see that you also used PixelArray, which I suppose took much less time to run?

[vast chasm]

sorry idk if you meant by PixelArray the way I represent my values yes

[brisk yew]

I meant this

but again, you can gain direct access to a surface as a numpy array via like pygame.surfarray.pixels3d which will return you a reference array, so modifying it, will modify the surface directly, so given how well you can handle numpy I don't think it should be an issue for you to write that efficiently too: https://pyga.me/docs/ref/surfarray.html#pygame.surfarray.pixels3d

also also, probably doesn't matter for your case, but as you may know, numpy is kinda slow with small arrays, so for like matrix operations you could opt for PyGLM: https://github.com/Zuzu-Typ/PyGLM

[vast chasm]

thank you. Just to be sure i can think of it as a view

[brisk yew]

yeah

[vast chasm]

i feel like numpy is performant enough

like yeah youre right but my main point is i dont want to learn a new framework

[snow hill]

wip 3D Gui in VR

(in Python)

[brisk yew]

that's alright, although I don't think there's too much to pyglm, it's pretty lightweight and probably just has a convenience method to do the matrix thingy you need, but sure, I don't think it even matters for your case now as you seem to be pregenerating that data

[vast chasm]

alrighty it has become very responsive but its rather small

idk if you can even see it but i guess thats nice

Does anyone know what books should I read to learn to develop a simple android game/app?
I have decent knowledge of python, HTML and CSS, a little knowledge of SQL and Data Bases.
As far as I know I could be using a frame work like Django to accomplish this, but I am not sure how the process works.

[thin pond]

how do i remove the line in balls in pygame

[unreal river]

What line?

[brisk yew]

Specifically Android? Uhh, Kotlin, Flutter and Java (but Java is not used as much anymore ig)

[ember meteor]

castration

[brisk yew]

You could use django for the backend of a web app, sure, and webs apps go on any device with a browser and such, but it's not an Android app

If you want Python options, there's Kivy, Pyqt5/6, even pygame and also flet

[thorny hawk]

And so are there any books that explain the process from skretch?

[thin pond]

pls explain

[thin pond]

like the line

[brisk yew]

Not any books that I know of, but I know for sure that django has a written tutorial on their website: https://docs.djangoproject.com/en/4.2/intro/tutorial01/ so uhh, if web app is what you're after, you can take a look here, although you may need to learn js at some point too, which again, no clue about books or written tutorials for that matter in this case

I saw someone on Youtube make a tutorial on how to make a basic and tedious-looking Minecraft game. And he used ursina to create it. But that point begs my question; is ursina capable of creating 2D or 3D applications (or both)?

I mean furthermore, I don't even know one rule about pygame. All the modules I know are tkinter/customtkinter, time, datetime and lastly pytz... 😅

[proper peak]

ursina is mainly a 3d game engine, though it supports some 2d stuff too.

[twilit cloak]

Oh, good to acknowledge. Thanks so much for your output. 👍

I'm curious, does pygame support 3D?

[brisk yew]

https://dontasktoask.com/

[brisk yew]

not sure what you mean by support, sure, people have made 3D games with pygame, but you can't just load in some 3D models out of the box like that

[true basin]

How does key remapping work, code-wise? You know, like in most commercial games where the settings allow you to remap an action to a certain key.

In all the exercises and tutorials I've done using Pygame (I'm still relatively new to Python and even more to Pygame though), it looks to me that key/action pairs are hardcoded into the source code.

[dawn quiver]

DOES ANYINE WANNA PLAY MY GAME THAT IS MADE BY A BEGINNER(ME)?

[brisk yew]

you can just have like a dictionary sth like so

key_map = {
    "up": pygame.K_w,
    "down": pygame.K_s,
    "left": pygame.K_a,
    "right": pygame.K_d
}

and then you'd use sth like

keys = pygame.key.get_pressed()

if keys[key_map["up"]]:
    ...
if keys[key_map["down"]]:
    ...
...

and done, if user wants to change their keys, codewise you just modify that dictionary and done
obvs you'd have some save and load mechanism for saving and loading user's key config and such, but yeah, this is the general idea

would be great if you could format the code as code

[true basin]

Thanks. That's easier than what I thought it'd be

[drifting wedge]

We would love to!

[spice bear]

hmmm

i need to know how to be a game dev

[drifting wedge]

There are many game modules you can learn in python. I suggest you to learn pygame as it is beginner friendly.

[brisk yew]

learn pygame, but I suggest using the pygame-ce distribution in particular

also being a game dev is mostly language agnostic, it's a bunch of concepts and whatnot, ig one way to practice those is of course through Python, yeah

[inner falcon]

Hello guys, I want to get into game development using Pygame soon, but I am wondering, am I ready to start learning Pygame if I have a solid understanding of:

-Variables and basic data types (integers,strings,floats,lists, objects).
-Loops (for loops and while loops).
-If statements (if, if else, elif).
-Functions.
-Basic Object Oriented Programming (I know how to define classes and methods. I understand what attributes are. I understand how to define objects).

I did not begin learning dictionaries yet.

[pine plinth]

i think so
(dictionaries are very useful/common, you definitely should learn them in near future)

[soft monolith]

Hi

Can someone tell me what game i should make for beginners

[wide saddle]

I have used tools like unity a lot to develop games. but when it comes to pygame, there is a point where I am confused about how we can design levels, which tools are there, if there is a video or documentation about it, can you send it?

[brisk yew]

well I can tell you that classes are just more powerful (at least syntactically) dictionaries

[brisk yew]

pong

[brisk yew]

there's Tiled for like map making stuff and also pytmx that can help you with loading all that stuff, but you can also make your own parser for the files Tiled exports and even make your own level editor, pretty sure Clear Code on yt has some tutorial that encompasses using Tiled, maybe the Zelda tutorial??? idk, but yeah, you can take a peek there

[wide saddle]

thx

[drifting wedge]

The most important to learn would be that you should be focusing on for loops and lists.

[soft monolith]

Thank you for the suggestion

the pygame library is not working in VS code for me why? even after installation and test on command prompt

[brisk yew]

it's more possible than not

[hoary nebula]

ok ill try for fun ksksks

[daring portal]

why is pygame not working for me????????????

[brisk yew]

I'd not suggest watching that tutorial

[daring portal]

but why is pygame not working??????/

[hoary nebula]

when you run the game,in the terminal apears like "welcome from the pygame comuinity"?

[daring portal]

yes

the command prompt is working but not VS code

[brisk yew]

well, it wouldn't appear for pygame-ce which is the better version of pygame

ironically pygame-ce is more of a community library than pg/pg

[brisk yew]

you probably have multiple python versions installed, for some reason

right?

[daring portal]

yes

[hoary nebula]

well,i didint know about pygame-ce

[daring portal]

what should I do?

[hoary nebula]

unistal?

[daring portal]

i need all of them

[brisk yew]

That's understandable, here's the announcement in this server, you can scroll down for more updates, but yeah #python-community message

[brisk yew]

no you don't

[daring portal]

the pythons are my children

I can't let one of them go

[brisk yew]

don't be silly, anyway, the other option is to select the correct version in vsc

[hoary nebula]

sorry for the bad engrish guys

[brisk yew]

somewhere at the bottom right corner

[daring portal]

ok

[brisk yew]

there's a button for python versions, click on that and then from the top select the Python version that you installed pygame on

although of course I'm obligated to tell you about pygame-ce, you can install it like so

pip uninstall pygame
pip install pygame-ce

it's basically a better version of pygame and yeah, old tutorials work with it too

[hoary nebula]

pygame ce is more complicate?

[brisk yew]

anyway, I don't like this tutorial, I'd suggest you watch one from Clear Code or DaFluffyPotato on youtube

[daring portal]

ok

[brisk yew]

no, it just has more features, more bugfixes and more optimizations, it's also a drop-in replacement, so you just need to install it and that's it, it should work out of the box like that

[daring portal]

I also saw this cool neural networking tutorial from harvard on free code camp

[hoary nebula]

ok understood

[daring portal]

is it worth it?

[brisk yew]

haven't seen it, can't comment on the tech anyway

but for pygame I'd suggest you watch Clear Code or DaFluffyPotato or even CodingWithRuss

[hoary nebula]

of couse not it must been complicated as potatoes

[daring portal]

of course not, it was very simple

[manic hawk]

Hello brothers, sisters and losers
I'm curious about how people implement collisions for high detailed surfaces that. Like a hill with several bumps, for example.

[tranquil girder]

For 2d or 3d?

[manic hawk]

same difference

both

[tranquil girder]

you just look up the height value in an array based on the player's position

[manic hawk]

and let's say I already have a blender model for the ground, so it has mesh data like vertices, normals and everything

[manic hawk]

would that account for slope?

[tranquil girder]

the way I did of for 3d terrain was that I started with a heightmap, a 2d texture, and the use that to find the height based on xz

no, but there's some math you can do to interpolate between pixels

[manic hawk]

that seems like a very nice solution, but I kind of want to account for slope in this case

eh I'm quite new to this so I have no idea the traditional ways of doing things

[tranquil girder]

https://github.com/pokepetter/ursina/blob/master/ursina/scripts/terraincast.py

[manic hawk]

damn an entire engine in python

thanks, I'll look closely at the code

[tranquil girder]

so it's basically this to interpolate

x, _, z = pos
point = height_values[int(floor(x))][int(floor(z))]

point_e =  height_values[int(min(w-1, ceil(x)))][int(floor(z))]
point_n =  height_values[int(floor(x))][int(min(d-1, ceil(z)))]
point_ne = height_values[int(min(w-1, ceil(x)))][int(min(d-1, ceil(z)))]

u0v0 = point * (ceil(x) - x) * (ceil(z) - z) # interpolated (x0, z0)
u1v0 = point_e * (x - floor(x)) * (ceil(z) - z) # interpolated (x1, z0)
u0v1 = point_n * (ceil(x) - x) * (z - floor(z)) # interpolated (x0, z1)
u1v1 = point_ne * (x - floor(x)) * (z - floor(z)) # interpolated (x1, z1)

point = u0v0 + u1v0 + u0v1 + u1v1  #estimate

I'm not going to pretend I understand it, but that's how to do it

and just moving to some height based on the position on a heightmap is way faster than using 3d colliders for example

[manic hawk]

yeah what I was kind of thinking was implementing a 3d collider that matches my mesh data

but this could be simpler

I'll try your approach first for sure

[tranquil girder]

That can work too if it's low poly enough. Like, if you have a terrain that's not really 2d, but has overhangs for example. Then using a mesh collider can be simpler

[formal gull]

Can someone help me with a 3d renderer using pygame?

[meager hill]

Hi any recommendations for ai tool that helps with gamedev graphics?

[honest panther]

hello

[summer reef]

Are there any python game engines with a gui?

[hexed hound]

whats an easy way for making a rectangle in the pygame

[unreal river]

just simply:

myrect = pygame.Rect(x, y, width, height)

[hexed hound]

i already have an image

[minor snow]

I have an a good game idea but i don't know where to start or how to find people that would help. I don't have any programing skills and i don't know people that do,Does anyone have any advice?

[vagrant saddle]

if game is not to be sold, then maybe propose idea in a coming gamejam and if people like it they'll probably join you - especially if you have some art ready at the time

you can find lot of game jam events on itch.io

[spring reef]

Hello guys, who has used the pyxel framework in their game projects?
What would you recommend, his or pygame or kywi for developing a real game?

What framework or engine is the best on python to date?

[vagrant saddle]

i think the good ones are listed in the channel topic

i'd recommend pygame-ce for start if game is 2D or Panda3D if it is 3D . But they are more raw engines than frameworks with fancy tools/gui

Hey guys, I'm designing a simple code that's supposed to blip an image, and move it to where your mouse is, and also rotate it in the direction of the movement, here it is:

from math import atan2, pi
from os import _exit as exit

import pygame
import pygame.locals as pg


def __get_rotation_angle(p1: tuple[int, int], p2: tuple[int, int]) -> float:
    x_diff = p2[0] - p1[0]
    y_diff = p2[1] - p1[1]

    return (180 / pi) * -atan2(y_diff, x_diff)


def main():
    SCREEN_SIZE = (800, 600)

    pygame.init()
    screen = pygame.display.set_mode(SCREEN_SIZE, 0, 32)

    tank = pygame.image.load('tanque.jpg').convert()
    rot_tank = tank

    x, y = 0, 0

    while True:
        for event in pygame.event.get():
            match event.type:
                case pg.QUIT:
                    pygame.quit()
                    exit(0)

                case pg.MOUSEMOTION:
                    _x, _y = x, y
                    x, y = pygame.mouse.get_pos()
                    rot_tank = pygame.transform.rotate(tank, __get_rotation_angle((x, y), (_x, _y)))

                case _:
                    pass

            x, y = abs(x % SCREEN_SIZE[0]), abs(y % SCREEN_SIZE[1])

            screen.fill((255, 255, 255))
            screen.blit(rot_tank, rot_tank.get_rect(center=(x, y)))

            pygame.display.update()


if __name__ == '__main__':
    main()

I'm pretty sure I'm calculating the angle correctly, but the image keeps "flickering", any ideas on to why?

[cobalt kayak]

Yes, check out panda3d

[fiery apex]

Also https://www.ursinaengine.org/ It uses Panda3d, but adds more functionality on top

one thing: don't use os._exit, that's bizarre, either raise SystemExit or use an exit flag

[celest osprey]

cool

this happens alot to me

[clear gazelle]

That's what source control software is for

[indigo yacht]

I don't like sys.exit() because it raises an Exception lol

[brisk yew]

I didn't even mention sys.exit(), I mentioned using an exit flag (e.g., while running:) or just do raise SystemExit
whatever you choose just don't use os._exit because you're clearly not supposed to use it
except the docs mention a particular case
also raising exceptions is not something bad...

currently you're just exerting excessive violence towards the process

[indigo yacht]

😿

[indigo yacht]

also raising exceptions is not something bad...

It's just that if the method is inside a try/except it won't work lol

I don't get what you mean by an exit flag?

[brisk yew]

why would there be a try/except catching a SystemExit? and if there is, then that's intentional, lol, also the stuff about cleanup handlers

[indigo yacht]

Except with generic exceptions I mean

[brisk yew]

that's probably bad usage of try/except then

[indigo yacht]

In my work, some of our internal libs from other teams only raise generic Exceptions

[brisk yew]

running = True
while running:
    ...
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    ...

[brisk yew]

that's fine, SystemExit is not a subclass of Exception

[indigo yacht]

Wait really?

!e

try:
  raise SystemExit
except Exception:
  print('Hello!')
else:
  print('Hi')

[frank field]

[indigo yacht]

Hm

I had no idea

[brisk yew]

well, now ya do

[indigo yacht]

Tysm:)

[brisk yew]

also pygame-ce cuz I'm legally required to mention it

[brisk yew]

also ofc this exit method

just don't do pygame.quit() before setting that boolean to False

[indigo yacht]

Yeah that makes sense, that was some dumb code provided by our professor

I'm taking a digital games elective and this mf suggested we use Python 3.4

Wanted to quit on day one

[brisk yew]

ya kinda don't need pygame.quit() at all because it's implicit, you probably did need it for your os._exit case cuz I feel like it wouldn't get called then, but otherwise ig it's mostly a good practice to add it anyway, although me to lazy so I don't use it knowing it will be called anyway

[indigo yacht]

Thanks for the help Matiiss 🙂

[summer reef]

Why did pygame-ce forked the orginal pygame? And what do they mean with these "impossible challenges" in their description?

It is a fork of the upstream pygame project by its former core developers, and was created after impossible challenges prevented them from continuing development upstream.

[proper peak]

There's some info in this video: https://www.youtube.com/watch?v=pYq9edSUaOw

[grizzled river]

Hello, I am new here, I heard Python is mostly to creat 2D games... or can i still creat a 3D game as well?

[vague hatch]

you can use stuff like PyEngine3D

or if you hate yourself you can do a 2d raytracer

[grizzled river]

Tnx!

[brisk yew]

there's Panda3D and ursina too

[vague hatch]

yeah but my suggestions better

[brisk yew]

your suggestion was last updated like 3 years ago, which suggests you ain't gonna get any new features added or bugs fixed anytime soon

[celest osprey]

ye i heard of urisna

[vague hatch]

true

[grizzled river]

So urisna is better or Panda3D

?

[vague hatch]

ursina

[grizzled river]

Ok

[vague hatch]

oh wait i thought you said ursina or pyengine3d

either one is good

in fact, try both and see what works for you

[brisk yew]

mby you need a general computer knowledge tutorial then?

worst case right click in explorer, create really any file from the menu, I usually create text files but it literally doesn't matter
when it asks for naming it, remove everything in that field including the extension and type your file name, hit enter, proceed through the warning and done

[valid dagger]

has anyone worked with OpenGL to write a game engine in here?

[feral grove]

How do you guys implement saving/loading in your games?

What I'm currently doing is something like this, though IDK if there are pitfalls with this approach down the line

class Saveable:
    def save(self) -> dict:
        # Save any built-ins like int, list, ...
        # Recursively call .save() on attrs which are also Saveable
        
class Weapon(Saveable):
    ...
    
class Character(Saveable):
    def __init__(self):
        self.health = 100
        self.weapon = Weapon()
        ...
        
annie = Character()
...
annie_data = annie.save()
# save to json or smthn

[valid dagger]

did you ever get any constant 2D graphics rendered to the screen? i.e. a crosshair or UI elements

Ah looking for someone who’s used OpenGL (specifically ModernGL but same principles apply) who’ve written 2D elements to the screen

[pine plinth]

That's a good way to do that.

[dawn quiver]

you can but i advice you not to, 3D games in python are slow asf, just use unity for that

[fallow finch]

python wasnt really created to make games

the bottleneck when writing games in python is stuff like the game logic (like the amount of function calls) or calculation

also, python can't be multithreaded like most other langs

due to the GIL

[vagrant saddle]

but they are fast to write. But anyway most game engines are written in c++ so python or lua are good enough for game logic

[fallow finch]

the "slow" will most likely not be caused by the fact its 2D or 3D

[dawn quiver]

fast to write and your game will run at 15 fps, python is not built for 3D games

[fallow finch]

its not built for games in general

but you can still make games with it

all games don't have to process a huge amount of things, and like pmp said the heavy things are made by c/cpp/... libs

[dawn quiver]

good for 2D games, if you know how to optimize them

[fallow finch]

its not a 2D/3D issue

[grizzled river]

Ok

[vagrant saddle]

you are making assumptions and obviously did not test much of python based game engine like Panda3D or Harfang3D

[fallow finch]

you can use opengl for 2d or 3d games, its the same thing

the bottleneck will be the function calls for example

not the fact the graphics are 3d

[dawn quiver]

make a game in Panda3D and i'll make the same game in unity and lets compare the performance ?

[fallow finch]

coder space made an excellent 3d minecraft game in python tutorial btw

but then if you add a lot of tickable blocks, mob ai..., it will be slow because python will have to process a lot of things

there's some possible optimization of course, like using multiprocessing to run a local server, but it will not be efficient like in java for example

[vagrant saddle]

sorry, but you are just spreading misinformation about python on a python game channel. and once properly compiled with mypyc : I bet you'll reach acceptable speed for way less complexity on python side.

of course unity tools may be more comfy but it is irrelevant to finished game

[fallow finch]

a lot of existing games could be written in python, i think the lack of tools to make games and the packaging is a main reason of why its not used for games

[vagrant saddle]

just for the joke, how fast can you make a rotating cube on web from a github gist with unity ? mine is already finished

[past junco]

No clue what you're after exactly but i can recommend looking into the arcade/pyglet duo; they use OpenGL and are pretty focused on 2D elements

[valid dagger]

I'm writing my own engine and didn't know if it can be done using OpenGL, can you mix pyglet and pygame?

[past junco]

you can certainly use OpenGL as the graphics api your engine will use to throw stuff onto the screen
mixing pygame with pyglet is likely going to ask for a lot of trouble since both do a lot more than just graphics, both open windows, can load images, have an event loop etc.

i don't even know whether pygame uses opengl tbh, only am aware of the fact it runs on SDL, i'll look into what that is real quick

[valid dagger]

I'm pretty new to writing the engine so was also looking to see if someone here had written some 2d elements in a 3d enviroment before by using PyOpenGL

I have some of it started just making sure I'm working in the right direction while I work through the errors

[past junco]

what do you mean by 2d elements in a 3d enviroment?
opengl is definitely capable of 3d, so if you write something using pyopengl it should probably work just as normal usage of the opengl api would

[valid dagger]

like drawing a crosshair, or static elements to the screen

[past junco]

i mean i don't see your exact question: whether it's possible to display graphics using opengl? yeah it is, that's its purpose and it's what pyglet and by extension arcade use
SDL too, but it can apparently also use Vulkan, Metal and Direct3D

so that means you already have something that produces a 3d environment?
and now you want to use specifically opengl to add UI/HUD overlays to that?

[valid dagger]

yes

[past junco]

Why not modify whatever you have right now that renders a 3d environment so it just adds on a hud?

What exactly is it that you have right now?

[valid dagger]

I have a quite a bit, I'm just unsure how to add the hud since I only have way to render 3d elements

[valid dagger]

https://github.com/poxford3/3DGameEngine here's the repo, I've since added a start to the 2d elements that I'm working on with some errors

[past junco]

typically 2d elements are added to a screen via a seperate draw call with far less complicated view/projection matrices

[valid dagger]

yeah I found a video that covered the formulas and math required to make the new view/proj mats and made some new vert/frag shaders I'm just having trouble getting the VAO to run @past junco

[tranquil girder]

I've done that before and the Panda3d one was faster. Although that was compared to when playing in the editor. My 3d python games don't get 15fps at least, but several hundred

[past junco]

well, i don't really understand your project, but here's what i see:
You have only one SceneRenderer, and all it seems to do is to just render one scene; i guess depending on what you want scenes to be that should maybe be changed to multiple ones?
The camera looks relatively important, but you also only create one of them for the entire game
I think you should have a camera that's basically a fully-fledged 3d transformer (your current one) but then another that just incorporates matrices producing a pretty simple transform+rotate+scale with which UI objects are then drawn

[valid dagger]

so implement a second camera?

[normal silo]

2D is just orthographic projection instead of perspective.

[valid dagger]

Yes, and I've been trying to implement the ortho proj in the same style that I did the other shaders, would that not be the way to do it?

[normal silo]

https://learnopengl.com/Getting-started/Coordinate-Systems

[valid dagger]

I've read through the Orthographic projection section of this one, is there something else I should read on here?

[normal silo]

Moderngl makes this easy for you by providing extra functions.

[valid dagger]

do you know what functions? I'm using ModernGL for my project

[normal silo]

No, that's all there is to it.

[valid dagger]

will see what I can find on their documentation page

[normal silo]

Basically, there is no 3D. Your screen is 2D. What makes it seem 3D is drawing with perspective illusion, which is accomplished via a transformation of the vertices that tricks your brain into seeing a 3D scene, same as how artists draw perspective "3D objects" on 2D paper.

If you do orthographic, you are not doing that illusion.

[valid dagger]

This is all just very new to me. Trying to learn as I write the code, biggest thing I'm trying to get my head around is conveying what I want to show up with what shows up

[past junco]

i can't help too well with 3d stuff, and due to some poor decisions my view matrix is pretty nonstandard so it won't help much, but can at least tell you the precise projection matrix i use:
Mat4.orthogonal_projection(0, CNST.GAME_WIDTH, CNST.GAME_HEIGHT, 0, -1, 1) using https://github.com/pyglet/pyglet/blob/71298baa36adfd16215eab6adc74d87864319702/pyglet/math.py#L746
This results in a pretty simple matrix that converts the plane starting at top left and stretching (W, H) right and down into the NDC
Since the game is pretty much hardcoded to that size, i only set it once
If you wanted your system to start at the lower left it'd be (0, CNST.GAME_WIDTH, 0, CNST.GAME_HEIGHT) i believe
the last 2 parameters are relatively useless for 2d i think

[frank field]

pyglet/math.py line 746

def orthogonal_projection(cls: type[Mat4T], left: float, right: float, bottom: float, top: float, z_near: float, z_far: float) -> Mat4T:```

[past junco]

yeeah i hoped i could help with this a bit better but turns out i forgot quite a bit of the process since it's been like a year already

[grizzled river]

Tnx all, I have a walking panda program now so far.

[normal silo]

Panda3D also lets you have your cake and eat it too. It's written in C++, and the C++ side mostly mirrors the Python side (for the core). You can write your entire game in C++ if you want. And Unity (AFAIK) does not let one easily write C++, so if you wrote your game entirely in C++ (although adding some Python would not really change this (which is its purpose, scripting the gameplay parts)), it would most certainly blow Unity C# out of the water in terms of performance. And this is ignoring that Unity is kind of slow to begin with because of bloat (which it trades off with a huge number of features). And also stuff like Cython exists to help if you really want to stick to just Python.

[brisk yew]

why would you mix them?

[valid dagger]

not sure, someone had just mentioned using pyglet for text and I'd already used pygame as a base in my engine

[brisk yew]

wdym text? pygame can render text, the ce distribution of pygame (which I'd suggest using) can even do text alignment and multiline text rendering

[vagrant saddle]

and also i18n + bidi + complex script rendering (at least on pygame-ce)

[valid dagger]

Would it be smart to use pygame to render the text as opposed to opengl?

[brisk yew]

Depends on your use case ig? It certainly would be more convenient I suppose, does opengl even support text rendering?

[valid dagger]

from what I see looking through their documentation they do but now I'm having trouble using pygame to render on top of my open gl visuals

[vagrant saddle]

maybe you could just composite bottom pygame / opengl render to texture / top pygame

[valid dagger]

tips on how to do that?

[vagrant saddle]

no idea how to do that on opengl, i use panda3d for that

[valid dagger]

well what method do you use to composite the two? @vagrant saddle

[vagrant saddle]

i used that one https://docs.panda3d.org/1.10/python/programming/rendering-process/2d-display-region

it's a 2D layer suitable for pygame surface and it is handled automatically by the engine

no idea how it works internally though

[lean sleet]

What if I posted about gdscript in here?

Would that break the rules?

[pine plinth]

Yes, because gdscript is not related to python

[knotty hamlet]

https://media.tenor.com/rlyqxiRiunEAAAAM/right-to-jail-jail.gif

[minor cloak]

is there some course for networking and game development?

im unsure of how to send limited information to the client

like in shooters you don't want the player to have access to all players position right?

although it might be faster to render

[dawn quiver]

is panda3D docs good? i never used it

please ping with any help. thank you !

[normal silo]

Basically you render your 2D stuff with an orthographic camera, and have it output to a separate buffer. Then use use that buffer as a texture for a quad (two triangles) that you stretch across the whole screen, now you have a HUD.

The most simple way to render text is to have a texture with the characters in it that acts like a sprite sheet, then in the shader it translates character values to UV coordinates (or on the CPU, whatever you prefer).

Where it gets more complicated is when you need more than ASCII, then you need to swap characters in and out of that texture (like a LRU cache), libraries like FreeType give you functions for creating that texture.

(Or stb_truetype, it's a bit more limited though, but much easier to use)

[wicked sail]

learn the language, then the framework/library/engine/etc

pygame and moderngl are nice. some people like panda3d too

[jaunty flame]

reposting from #pedagogy:

somewhat open-ended question - i've been reading martin fitz patrick's book on PyQt5 development and i'm starting to realize "just the one book" isn't going to be enough to get from "i can tinker a couple things" to "i should be able to, with time and effort, code any app i'm capable of imagining".

for now, the two kinds of applications i'm thinking of creating are:

• video games (2d, the "simple" visual novel / dungeon crawling kind)
• creativity software (focused on text/image, perhaps a paper doll app for instance)

both of these deal with images, so the bigger question on my mind right now is graphics. it looks like PyQt is meant to handle "the wrapping around the content", but i'm having a hard time evaluating whether it can - on its own - handle graphics. could i theoretically compose a game screen in PyQt, or should i include something else such as OpenGL for that kind of thing?

(also, is there any book recommendation around going in that direction? dynamic graphics in python, i mean)

[normal silo]

You can render a OpenGL scene into a PyQt application.

https://doc.qt.io/qt-5/qglwidget.html

You can also probably embed pygame-ce into it.

[jaunty flame]

Thanks. So to clarify, the idea would be to use Python to compute whatever situation I want to represent/paint, throw arguments from Python to OpenGL (creating an OpenGL scene, which I assume is basically a canvas), and then render/display the OpenGL scene in a widget in PyQt?

[normal silo]

OpenGL renders into some OpenGL context, which Qt will create for you. If you then start calling OpenGL functions, it will use that context. Basically like a canvas, but OpenGL is more complicated than simple drawing functions you might find in vector graphics libraries.

If you want, you can use some game library that uses OpenGL, and then its scene should be rendered into the widget.

Assuming the game library supports not having its own window (embedding).

Unless you really want Qt it's probably not worth the effort though. I would ditch Qt and just directly use a game library/engine.

Qt is more for applications.

[jaunty flame]

[ember narwhal]

I made an image using Krita that consists of multiple adjacent areas (let's call each color space) that are split by borders and each area has a unique color.

I loaded this image to pygame and blitted it.

I use the get_at function to retrieve the color of a pixel that I click.

The problem is different points in a color space give RGB values with slight variation. I need a color space to be homogenous.

I'm trying to create a world map consists of countries with unique color, so when I click a country I will fetch its data since their RGB value are paired with their data.

Since different points of a country land gives different RGB value, this causes a problem.

If anyone knows why, it would be great. Thanks!

Edit: The problem mostly occurs near the edges of color spaces.

[brisk yew]

well, then the colors there are just a different shade

Here's a similar thing I did a while ago: https://github.com/Matiiss/wip_pygame_examples/tree/main/examples/map_regions

[ember narwhal]

I disabled the anti-aliasing while drawing the color spaces so they are fine in krita but not in pygame. I will read your post.

[brisk yew]

what format did you save the image as?

[ember narwhal]

jpg

[brisk yew]

use png

jp(e)g uses lossy compression

if anyone would help id really appreciate it

[vagrant saddle]

you could help us first to help you by describing your problem in details. Also small portions of code without entry point and assets are rarely usefull. It is better to publish or zip the whole failing program

[nova bloom]

Is panda 3D good for making 3D games?

[brisk yew]

ursina...

[brisk yew]

what does good mean in this context?

like, you can make 3D games with it, pretty good ones too and they apparently can be really fast

[rancid sigil]

woo hoo!

i love the source engine

[tiny vault]

hey guys

whats game devlopment like

tell me

[tacit geode]

like ?

what u wanna know

how it feels ?

[tiny vault]

yes

and whats it like

is it difficult or ez or stuff like that?

[tacit geode]

in professional sense you have some deadline before which you gotta ship the game

[tiny vault]

oh

[tacit geode]

its difficult making games is not easy

unless you mean really simple games

[tiny vault]

whats it like being in a games dev team?

[tiny vault]

i c

[tiny vault]

?

[tacit geode]

stressful

[tiny vault]

ohh

btw almost how much are they paid

just asking

[tacit geode]

well im in ml so idk much abt them but the big studios must pay em a lot

like Rockstar, Ubisoft, Paradox etc

[tiny vault]

what youd say bout supercell?

[tacit geode]

idk you gotta check their career website

company seems nice

but they make mobile games

[tiny vault]

wait is there something like that

yessir

[tacit geode]

?

what

[tiny vault]

a carrer website?

[tacit geode]

yeah 💀

most companies have them

[tiny vault]

lmao i literally didnt know bout that

oh yes there is

[tacit geode]

game dev is very stressful

i dont wanna do it

[tiny vault]

oh

what about those 'community managers'?

what do they do

[brisk yew]

pretty sure game dev is one of the worst industries you can get into as a software engineer

[tiny vault]

wait fr

i thought it was the best

💀

i lived in a delusion for so long

[tacit geode]

They are responsible for building and maintaining digital relationships between brands and their consumers.

[tiny vault]

wow guys

you really are into these things

[brisk yew]

if you enjoy it maybe, but it's low pay, overtime work, very stressful and whatnot or so I have heard

[tacit geode]

game dev is the last last last option i will ever choose as a career

[tiny vault]

woah man

[tacit geode]

?

wdym

[brisk yew]

isn't that like a lot of software jobs now?

[tiny vault]

like knowing all this stuff

and all

anyways, nice to meet you guys!

[brisk yew]

all this stuff being, don't be a game dev at a company, lol

[tiny vault]

yup

[tacit geode]

yeah pretty much but still you have to do things which makes you earn money

[brisk yew]

if you enjoy making games, sure, go for it, I personally wouldn't choose it as a career tho

[tiny vault]

I am a computer science student btw

[tacit geode]

lol you will know with time

[tiny vault]

still learning stuff

[tiny vault]

lets see what the future holds for me :/

[tacit geode]

do what you want don't fall into people's recommendation

[tiny vault]

yes

[brisk yew]

I for one, sometimes make games myself using pygame-ce and I also contribute to its source code, FOSS contributions is sth you should try sometime, pretty sure employers look for that too now

[tiny vault]

i hear from all but listen to me

myself

im self reliant except i take tips about experience from people

so that i can decide for myself

[brisk yew]

sounds like a good approach, tho don't forget that you don't have to make all the mistakes yourself, you can learn from others too

[tacit geode]

i remember a lot of students joined ml class

and like 80% of them dropped in the second month

lol

[tiny vault]

so true

[tiny vault]

lmao

you got to be kidding

[brisk yew]

why?

[tacit geode]

they weren't able to understand the stuff that was being teached only joined cuz they heard ml hype

also didn't had any interest in it

only for money

[tacit geode]

kek

[brisk yew]

that's an interest, lol, but I gotchu, yeah, motivation to actually learn cs and stuff

I've heard of lots of people dropping out because they were in it just for the money

[tacit geode]

lol money i think is the biggest motivation for some ppl to learn cs

[brisk yew]

it's a pretty good motivator ngl, but yeah

[tiny vault]

me

[young gate]

how is this shop?

admittedly nothing is buyable yet but going to add that soon

[pine plinth]

cool!

[crimson mirage]

Pretty cool

In the meanwhile though, would anyone like to share their thoughts on the concept of this collision engine?

[proper peak]

so, just iterate over all pairs of objects? that's the basic way, sure.

[crimson mirage]

Any thoughts on how I'd optimize it?

[proper peak]

I think people use spatial partitioning for that. The basic idea is that you put all your objects into an oct-tree (or quad-tree for 2d) that recusively subdivides the space into cells, such that objects that are on a cell boundary are in both cells. Then, only objects in the same cell can possibly overlap, so you only need to check objects in the same cell.

here's a nice overview of different methods: https://www.cs.cmu.edu/~jbruce/thesis/chapters/thesis-ch03.pdf

[crimson mirage]

I see. Thanks.

[rough crest]

looks good

[viscid maple]

Hello, everyone,

The rules of this channels allow users to upload GIFS of ongoing projects, but since they are not a very good medium for some specific demonstrations, allow me to use a very tiny video instead.

The software shown above ☝🏽 is completely free, open-source and released to the public domain. I'm sharing it here on the occasion of its 1.4 version release and because I believe it is directly related to the topic of this channel. I myself (the developer) use it to generate some animation data for a game I'm developing. You can download it right now with pip:

pip install --upgrade nodezator

And learn more about it here: https://github.com/IndiePython/nodezator

There's also an online manual which is available within the app as well: https://manual.nodezator.com/

Let me know if you have any questions, I'll be happy to answer them.

[round yarrow]

Hi all!
Was hoping you guys could help me with something.
I'm trying to develop some GUI software that would allow me a good bit of flexibility in terms of what can be displayed, but also (and this is important) allows me to create two windows.
My first though was pygame. I have used it several times in the past, and it's pretty easy and straight forward to use. Unfortunately, I read only that pygame does not support multiple windows. Damn...
I then found pyglet. Allegedly it supports dual windows, but I didn't manage to get it to work properly. After pyglet, I found arcade. It looked promising. I was able to open two windows, but the moment I added Views to draw on, I had the same OpenGL problems as I had with pylget. The lack of documentation on some of these features (which I feel are core features) is also a bit off-putting....

So I was wondering... Could any of you suggest me some graphics library that I could use?
In short what I need:

• Be able to display pictures and draw on them
• Be able to have a menu with controls (DIY'ed menu with elements is fine, doesn't need to be tkinter-is)
• Be able to open and draw on two windows

Thanks!

[brisk yew]

Pygame can support multiple windows, the api is still experimental, but pygame-ce 2.4.0 should make the window api official and you'll be able to create as many windows as you wish
currently it's either possible with that same API pretty much, but it's technically experimental and some stuff may change
the other option is to use multiprocessing

[round yarrow]

pygame-ce? That's a fork?

Mhmmm, just googled it now. Didn't know about the fork.

[brisk yew]

yep

[round yarrow]

I always used the vanilla pygame.

Sounds like it's a rebelious forks? In my experience, FOSS projects die when this happens.

[brisk yew]

well, pg/pg should have roughly the same experimental api anyway
nonetheless pygame-ce is better and pretty much as vanilla as can be

anyway, here are the two solutions of mine I provided in pygame's dc server (the contributing stuff and the whole thing is focused on ce now, pretty much all of the core contributors are now working on pygame-ce, so it def shouldn't die, lol) https://discord.com/channels/772505616680878080/1133140731733749800

[round yarrow]

Thanks! (I joined that servera minute ago lol)

That looks indeed like what I'm hoping to do.

But do I understand you correctly that these two methods are alternatives to using pygame-ce 2.4.0 API?

[brisk yew]

well, that new api is not finalized yet, and that version is not released yet, but the given solutions should be compatible with either pygame, yeah

[round yarrow]

Ye, I noticed it isn't released yet. 2.3.0 is the latest.

Was looking into compiling it from source.

But maybe to be futureproof, I shouldn't do that.

Sounds like it's opening an unnecessary can of worms.

[brisk yew]

dunno, can't say pg/pg is gonna march too far forward either since it's now one guy who's left there with any kind of power

[round yarrow]

. 😄

[brisk yew]

both the original and the fork?

[round yarrow]

Often, yes.

[brisk yew]

well, crap, that's an unfortunate fate

[round yarrow]

It would be, yes. Because pygame is like "the" library everyone goes to for Python game design.

It's so easy and accesible to beginners.

[brisk yew]

mmm, why do you think that happens btw?

[round yarrow]

It's just something that I've seen happen a few times.

Usually projects like these are either carried by a single person (in that case a rebelious fork can't happen, so this case doesn't apply), or by a small group of people. Of that group splits up, not only is the dev work doubled, but the gain is also halved or worse. Because most users will not be aware of the split.

This is assuming a clean 50-50 split of course.

Worst case, no one moves to the neo-version, except for all but one of the devs.

And unfortunately that worst case is something that happens a lot.

Because some devs are very protective of their work, which often results in heated disagreements and disbandments.

[brisk yew]

well, so far we've got support from ytbers and other platform "managers" and we have a whole dc server, so people def do find out and move to ce

[brisk yew]

anyway, for pygame multiprocessing and using set_mode currently seems like a safe bet for multiple windows, you just have to manage memory across those processes which shouldn't be too hard, but still has to be done

[round yarrow]

That's a good thing of course. Fingers crossed that it'll be enough! 🙂

[round yarrow]

Thanks! Am going to see if I can get it to work that way!

[round yarrow]

What would you advise to create a UI? I was planning to create toolbars with pygame-code, but maybe that's reinventing the wheel?

[pine plinth]

There is no good GUI lib for python

[round yarrow]

Mhmmm, how about embedding some pygame in PyQt?

[red tusk]

Define "good gui lib". For example, TortoiseHg is written with PyQt

[normal silo]

If you want to use a game library that has multiple windows easily, then you could try Panda3D. It has its own GUI.

Not sure if anyone has tried this, but it may be possible (probable) to embed PyGame into Panda3D...

[vagrant saddle]

yes it's possible

[normal silo]

Not sure how that would play out with multiple windows, since that is a PyGame side limitation.

[vagrant saddle]

you can use different pygame surfaces

[normal silo]

I guess you would call the pygame draw and switch between them.

Ah yeah.

[vagrant saddle]

here's a minimal sample with no event passing https://github.com/Schwarzbaer/panda_examples/blob/master/buffer_protocol/pygame_to_panda3d.py

[normal silo]

PyGame can use OpenGL rather than software render right? I was thinking about that, it would involve setting the OpenGL context for PyGame and calling draw for each window in a task.

[vagrant saddle]

that would be probably way less portable than just pygame+panda3D dealing with 3d layer

[normal silo]

Yeah, i'm just thinking of avoiding the copy from GPU to CPU and back to GPU.

Although if software rendering is used, it's only CPU to GPU.

I think it can be done via setting the render sort order, having tasks in between that are for the pygame scenes.

[vagrant saddle]

above sample also seem to work with pygbag so on web browsers

+1 for not using opengl because it is gles on web

[young gate]

i finished up the shop

[random stratus]

thats really neat :0

[young gate]

thanks!

[meager plover]

wow its nice !

hi guys... i want to share my work for we are devloper game using pygame

i gonna try to pblish my demo game for tomorow

if you want to see or try my game you can chek it

https://einvisense.itch.io/einlanders

i was learning pygame for 1 year dams it was so freaks and tired

but cheers guys 🍻 🍺 !!!

i hope my game was playing correctly on other computer

i am only use 2 module pygame and pyinstaller.

i was create my game coding for 4056 line code.

thankyou python and pygame. frome me as game programer.

i coding this game for 2 month and i enjoy it

[meager plover]

vid game play.

[unreal river]

nice game bro, but no offense, is this a fake loading screen?

[pine plinth]

Probably

Looks too smooth

[meager plover]

yea it was for make delay game, could it can be a real loading screen but hig coding needed

so it will bring enjoy on the game

[dawn quiver]

this is your custom ui elements or you are using lib?

[young gate]

added minecraft style item selection from inventory

[young gate]

i got them open source from itch.io

[quick granite]

anyone know how to add a gravity effect in this code , all the object does is just bounce all around the screen ,wanna make it so it has some gravity logic

[red tusk]

@quick granite Physics. The vertical component of the speed (ball_obj_speed[1]), increase it by a tiny bit amount each frame. This is called "uniformly accelerated motion", trajectory is parabola

[meager plover]

thankyou

[meager plover]

you can use increment on screen or object you wanna add into variable

use pygame math.v2 and use

[meager plover]

x or y on that

[dawn quiver]

Try implement games with oop paradigm otherwise your codebase will be trash.

[pine plinth]

Not necessarily.
Code that uses OOP can be trash, and code that doesn't use OOP can be good

[dawn quiver]

In game dev context oop is the only way out

[dawn quiver]

when i made a basic platformer last year, i added a boolean that would check if the sprite was colliding with another sprite/platform

while the collision value was false, the y value of the player would decrease whereas if the player was colliding with soemthing, the y value would stick

let me grab the code rq (its c# but logic still applies)

and yes following an OOP paradigm will help you organise your code

collides function just returns whether the sprite hitbox is intersecting

https://www.pygame.org/docs/ref/rect.html

refer to this

[pine plinth]

Not really. There are a lot of different ways to write code

[dawn quiver]

@pine plinth yes.but i cannot imagine how to implement even simple physics with no oop.oop way just create physcis class and inherit object. And the best part you can implement this logic all classes which has same interface

No.absolutely no i didnt see anybody in my life uses other paradigm in game dev real production projects

Probably bethesda uses other paradigm thats why their games terrible

[normal silo]

Then I will give you one, Overwatch. It uses an ECS.

(Which falls under data-oriented design (DOD))

[little apex]

hey I'm making a 2d tank game for fun. The tank has a turret which is controlled seperately from the body of the tank. Would you suggest the turret being it's own class or a subclass of the tank

[normal silo]

Also pretty much every very old game written in assembly. There are a lot of them.

(Can't even afford the vtable lookup used by OOP, too slow)

[dawn quiver]

If your tank game has only one tank then there is no need to create class for each part.other wise i think factory pattern is better in that case.create tank factory class and create classes for each part.also you can create parent class for each part.then use this part classes to build tank object.

[dawn quiver]

That is another universe.they are genius.

Programmers code 8 bit systems are rockstar of this field

[little apex]

yes there is only one tank, how should I approach a subclass (i've never done one before)

[dawn quiver]

Then no need tp create any class except tank class itself.

And interface if you want.

Inheritance is evil if you use pointless

[little apex]

yeah but i kinda want to just to learn how classes work

any good sources?

[dawn quiver]

Hmm.real python website always good resource

[little apex]

alright

[dawn quiver]

I cannot remember exact dns of realpython

I think it is realpython.com

[little apex]

k ill try it

[meager plover]

i have some issue that we are using pyinstaller when it compresed into a zip or rar could it be the fill losing something and it make acrash on a game we made...becouse pyintsaller need corectly data on main that was we build. #it just a report and notice

i was download game from de flufy potato and it kind like missing file and game cant run well.

could it be happen when file was extract. ?

[marble jewel]

Isometria Devlog 27 - Multiple Levels and Networked Chests https://youtu.be/njHemLDLLh4

[brisk yew]

when C

[brisk yew]

using lossy compression for arbitrary file formats is asking for disaster, so no, I mean, it could happen, but probably not because it was lossily compressed

because it uses lossless compression

[pine plinth]

You can implement physics using ECS paradigm.
I think that would be even simpler than OOP

[meager plover]

ok thankyou

[tacit geode]

Oop is bad

Just makes things complex

classes for this classes for that

ECS is much better for games takes a bit of time but will help you thousands of hours of debugging

[tacit geode]

I'm making an isometric engine in C didn't had any problems until now

[tacit geode]

Roller-coaster tycoon

[tacit geode]

Also cuz classes in cpp are bad

[brisk yew]

While I agree that ECS is probably one of the best if not the best architecture for making games, you can still use OOP to implement an ECS system. Depending on how broad of a definition you want to use for what counts as OOP.

[tacit geode]

Agreed

[normal silo]

A lot of games also combine multiple styles. E.g. functional reactive programming (FRP) is commonly mixed in, or used as the main driver. It goes by many names: "events," "signals," "listeners."

ECS started out as a variant of it that also used data-oriented designed (before that term was a thing too).

Back then known as act/react systems I think.

If you have a much more loose definition of ECS it can predate the use of OOP in video games (functional programming also can be consider to have predated it).

("OOP" as with inheritance hierarchies)

[sly oak]

Hello, I'm trying to start learning about game development, Any expert here that can tell where to start?

[pine plinth]

Check pins

[normal silo]

This is one of the main issues with comparing ECS and OOP. ECS has a pretty strict definition, but it does not seem that developers can agree on what OOP means.
