game-development

[gilded grove]

even tho i did pip install pygame

in both terminals

and the error matches the error message in stack overflow

[potent ice]

Did you select the python interpreter for your project in the lower left side?

[gilded grove]

how do you do that?

am noob

[potent ice]

Click the area in the bottom bar related to what python you are using

mine says "python 3.9.0" atm

Did you just open an single file or a directory?

[gilded grove]

i made a folder called gameCode

and beneath that i added main.py

[potent ice]

You picked "Open Folder" and selected the gameCode directory?```
gameCode/
main.py

[gilded grove]

yes

main.py is a file under gameCode

i think the stack overflow thing is right but i don't know how to fix it

[potent ice]

Once you have picked a python interpreter a .vscode should appear ```
gameCode/
.vscode
main.py

[gilded grove]

i googled how to pick a python interpreter

[potent ice]

Can you link the stackoverflow post?

[gilded grove]

https://stackoverflow.com/questions/50569453/why-does-it-say-that-module-pygame-has-no-init-member

[potent ice]

do you even have the python plugin?

[gilded grove]

yeah i got that

[potent ice]

Ok. Your lower blue bar looks like what?

[gilded grove]

python 3.7.4 64-bit

i am sorry i'm being a pain

i just tried to do a web app but it devolved into creating a social media app so i wanted to do something simpler

need something for my projects

[potent ice]

CTRL SHIFT P and select "Python Terminal"

[gilded grove]

crtl shift p does nothing

idk why

[potent ice]

View -> Command Palette

[gilded grove]

ok what should i type in

[surreal talon]

I was wondering if someone could help me out with pygame. Im busy making a game that pretty much uses lines all the time. And a ball that bounces off of the lines. I need to do collision to check if the ball collides with a line.
The ball is a rect btw

[potent ice]

@surreal talon you just ask the question 😉

@gilded grove "terminal" and pick "Python: Create Terminal"

[gilded grove]

ok did it

now what

[potent ice]

python --version shows what?

[gilded grove]

2.7.16

F

[silver tinsel]

[potent ice]

uhh

[silver tinsel]

python 2

[gilded grove]

HOW

[potent ice]

What OS 😄

[gilded grove]

macos

are you telling me i have been running everything on 2.7.16

i'm gonna cry

ok i'm over it

[silver tinsel]

[potent ice]

run using python3 main.py

[gilded grove]

just type in python3 main.py? in the terminal

[potent ice]

yes

[silver tinsel]

ye

[gilded grove]

command not found

[silver tinsel]

oh wait is it different for macos?

[gilded grove]

python3 main.py

[potent ice]

python3<tab> and see what appears?

[gilded grove]

bash: syntax error near unexpected token `newline'

[surreal talon]

Well could ya help out. Ive been scratching my head for the past 2 hours

[gilded grove]

oh god if it takes me a whole day to set up pygame

just lucky me ig

[potent ice]

nono. press the TAB key

[silver tinsel]

im sure it wont das

[potent ice]

python3<hit tab key and see what appears>

[gilded grove]

ok it goes to gameCode

[potent ice]

you might have a python3.7 for example. I don't know if you have installed any other python versions

[gilded grove]

python 3 gameCode/

[potent ice]

no spaces

[gilded grove]

ok

[potent ice]

python[TAB]

[gilded grove]

python python.app python2.7-config python3.7 python3.7m pythonw
python-config python2.7 python3-config python3.7-config python3.7m-config pythonw2.7

whom'st put 2.7 on my mac

[potent ice]

ok cool. python3.7 is there

python3.7 main.py

[gilded grove]

python: can't open file 'python3.7': [Errno 2] No such file or directory

[potent ice]

uh. Just python3.7

[gilded grove]

(base) Rahuls-MBP:pygameStuff rahuldas$ python3.7

did i just dox myself

F

[potent ice]

ok, so it works

oh it's Anaconda

[gilded grove]

is that the problem?

[potent ice]

It seems you are in a virtualenv called base

[gilded grove]

https://tenor.com/view/kermit-suicide-flip-jump-crash-gif-5140737

[potent ice]

You probably need to pick that from the python interpreter list

[silver tinsel]

oh yeah i had that same problem when trying to do a project in a new venv

[gilded grove]

how do i pick it

code palette?

[potent ice]

The blue bar. lower left

[gilded grove]

ok i clicked the base one

now what

[potent ice]

hm. there should be a list if things?!

[gilded grove]

i don't see anything

[potent ice]

You can also go here : https://discord.gg/h8ujJGCcq3

[gilded grove]

thank you for being patient w me

and helping

[potent ice]

View -> Command Palette.. and pick "Python: Select interpreter"

[gilded grove]

yep and i clicked the base

[potent ice]

ok. make python terminal again

[gilded grove]

ok done

[potent ice]

python --version

[gilded grove]

Python 2.7.16

https://tenor.com/view/kermit-suicide-flip-jump-crash-gif-5140737

throw away the entire computer at this point lmao

[potent ice]

It this something weird anaconda is doing?

[gilded grove]

i don't know tbh

[potent ice]

It does say (base) in the command line?

[surreal talon]

Thanks

[potent ice]

okok. Let's do it the brutal way then.

[gilded grove]

this wasn't the brutal way?

okie i'm ready

[potent ice]

python3.7 -m pip install pygame
python3.7 main.py

[gilded grove]

python3.7: can't open file 'main.py': [Errno 2] No such file or directory

[potent ice]

but you did ran it earlier..

#game-development message

[gilded grove]

this is what happens when i run it

[potent ice]

ok, so it works?

[gilded grove]

no

    if keys[pygame.K_LEFT]:
        x_p2 -= v_p2
        if x_p2 <= 500 + w_net:
            x_p2 = 500 + w_net
    elif keys[pygame.K_RIGHT]:
        x_p2 += v_p2
        if x_p2 + w_p2 >= 1000:
            x_p2 = 1000 - w_p2

like over here

pygame is underlined red

so i can't move them properly

it's screwing up the entire game bc pygame keeps getting underlined as red

[potent ice]

which python3.7

Then use that info to pick the right python interpreter

[gilded grove]

i clicked python 3.7 64-bit base

so it should be working

[potent ice]

no other listed?

[gilded grove]

HEY

I DID IT

i mean

YOU DID IT

WE DID IT

i'm so sorry for taking your time

i'm not used to VSC i used repl.it in college and intellij after

[potent ice]

yay. I think there are some notes on using vscode with anaconda

[gilded grove]

uhhh

bash: Python 3.7.6 64-bit: command not found

when i hit the green arrow to run my code it just says that

the red underlined things went away

[potent ice]

You might be better off making your own virtualenvs, but if you stick to python3.7 main.py and python3.7 -m pip install <package> you should be fine for now 😄

great 🙂

[gilded grove]

it doesn't work

no pygame window pops up

it was popping up before when the pygame's were underlined red

[potent ice]

No output in terminal?

[gilded grove]

bash: Python 3.7.6 64-bit: command not found

nope

now the blue bar at the bottom says select python interpeter

[potent ice]

I guess you just have to pick the right one

[gilded grove]

~/opt/anaconda3/bin/python

damnit

now the red underlines are back

https://tenor.com/view/kermit-suicide-flip-jump-crash-gif-5140737

[potent ice]

Because that python version doesn't have pygame

[gilded grove]

so what should i do

install a version of python that has pygame?

[potent ice]

can you screenshot what interpreters are available?

[gilded grove]

the /opt/anaconda3/bin/python and ~/opt/anaconda3/bin/python both don't work

and the 2.7.16 64-bit probably won't work either

so what version of python contains pygame

pip install python 3.7.7?

can i do that?

[potent ice]

one of the 3.7 versions I guess

[gilded grove]

ERROR: Could not find a version that satisfies the requirement python (from versions: none)
ERROR: No matching distribution found for python

do i have to install it from the site again

[elfin kernel]

hey i need some help with diagonal movement can someone please help me ? #help-cherries

[potent ice]

hmm. It's hard to debug this because I haven't really used conda much

[gilded grove]

i'm sorry

[potent ice]

It has it's own system for environments etc

[gilded grove]

ok ok ok

what if i installed VSC's version of python 3.7.7

is that possible??

[potent ice]

If you see a (base) or (conda) prefix it might just activate some environment by default for you

in terminal that is

[gilded grove]

i see a base: conda

pls this is giving me a headache

[potent ice]

yes, so it force activates some environment on terminal creation for you

[gilded grove]

idk what that means but go off i guess

[potent ice]

pick the last environment on the list

[gilded grove]

that doesn't work either

~opt/anaconda3/bin/python doesn't work

[potent ice]

It says "no interpreter found" or something?

[gilded grove]

no it opens a pygame window

but it still has pygame underlined in red

did you know what they were saying in that stack overflow post from way back

https://stackoverflow.com/questions/50569453/why-does-it-say-that-module-pygame-has-no-init-member

this one

[elfin kernel]

i really need help im stuck with this problem ...

[gilded grove]

i'm trying it in repl.it

[potent ice]

@gilded grove Isn't there some anaconda UI/program to set up things?

I think this this problem is more about learning how anaconda works. I don't know why you installed that. Maybe for good reasons of course.

[gilded grove]

i installed anaconda for jupyter notebook

back when i was doing DS/ML stuff

nope i can't see anything with repl.it bc the window is too big

F in the chat for me ig

[potent ice]

My assumptions with conda is : If you have an enviroment enabled you can simply type python and it will use the python version the environent has.

[gilded grove]

dude

Python 2.7.16 (default, Jan 27 2020, 04:46:15)
[GCC 4.2.1 Compatible Apple LLVM 10.0.1 (clang-1001.0.37.14)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

why is it that the blue bar says 3.7.6

but when i type python in the terminal it says 2.7.16

i'm so mad

i think we spent like an hour trying to fix this

[gilded grove]

should i open a help channel or something?

[potent ice]

I think you should check the conda docs. Make a new environment and activate it

Restart vscode and select that environment

[gilded grove]

idk dude if python 2.7 or whatever doesn't work

why does it open a window

???

There is a security setting that you can set in .pylintrc that whitelists native code modules for pylint. I don’t remember the exact setting but try googling for ”module numpy has no member” and you should find it.

do you know what this means??

[potent ice]

I don't have this problem with pygame myself. You might be chasing the wrong issues here

[gilded grove]

https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#creating-an-environment-with-commands

i found this

ok i'm gonna try this rn and let you know how it goes

usage: conda [-h] [-V] command ...

what does that even mean

conda: error: unrecognized arguments: --pygame

[potent ice]

What does pygame have to do with this?

The goal is to make a conda enviroment and activate it

[gilded grove]

oh shit i did it

[potent ice]

How?

[gilded grove]

conda create -n pygame python=3.7.7

[potent ice]

and you activated it?

[gilded grove]

does that mean going to the command paleltte and selecting it

bc if it does then yes

or do you mean $ activate pygame

i forgot the syntax

[potent ice]

conda activate pygame maybe? Random guess ..

[gilded grove]

i had to reinstall pygame in the new environment

but whatever

ok good shit

thanks

[potent ice]

that is perfectly fine 🙂

[gilded grove]

i kind of copy pasted someone's github code for a badminton game but i did cite them

so now i'm gonna add a menu

add players

and add the badminton rackets swinging

[potent ice]

In the future you might want to make your own venv, but I did not want to dig into that because conda would fight it!

[gilded grove]

uhhhhhh

what's a venv

i've seen a lot of people mention it

[potent ice]

What you just created with conda

It's kind of a separate python installation for your project

When you install python packages it only ends up in that version

This is essential when working with a lot of projects because different projects may require different version of libraries

Without it you are pretty much doomed as a python software developer 😄

[gilded grove]

ohhh

ok

thank you dude

much appreciated

[potent ice]

No problem.

[gilded grove]

you got any good vids on sprites in pygame

nvm i can find out myself

[potent ice]

https://www.youtube.com/DaFluffyPotato has lots of good stuff

Also the pygame community is a good place to ask : https://discord.gg/h8ujJGCcq3

There are so many pygame resources out there it's almost hard to know where to start

[gilded grove]

Yeah I’ll ask questions there if no one knows here

[elfin kernel]

can someone help me quickly pls?

[potent ice]

What is the problem?

Feel free to ask in #community-meta if you think this is a mistake.

[bright coral]

I’m working on a mixed-reality portal for python!!! It will mostly be based around Augmented and virtual reality!

[grim abyss]

um wow....that was from wayyyyy earlier

[potent ice]

@bright coral What libraries?

[real peak]

Haven't done any gamedev yet but I'm curious how you guys handle savegames. Do you just simply write .csv files?

[potent ice]

Probably easier to write a json file. You can dump a dict easily

Depends what you are saving I guess?

If you're just saving some metadata, json is a quick and easy one

[hybrid sun]

if you write a json file then players can edit it

encrypt it with layers of base64 and binary if you want

[bright coral]

i only started recently, i haven't imported any library yet

[sweet loom]

I am literally new to coding just a week old

I donno what libraries are

What are libraries everyone keep saying library

[real peak]

A library is a collection of packages. A package is a collection of modules (classes, functions)

[sweet loom]

Ok..

Like assets ..?

[real peak]

Packages are what you will be most concerned about... in your script, usually at the top, you can use import to import packages

[bright coral]

not really

[real peak]

Sort of, yeah, for simple example you have the playsound package which allows you to play sounds

[bright coral]

it's complicated, but i can dumb it down

[sweet loom]

and if I have to get one?

.import playsound

?

[bright coral]

it's a line of code, not a discord bot comand

[sweet loom]

Nono

Im saying if this is correct to get one ..

I'm asking can I write that .

[real peak]

https://www.youtube.com/watch?v=CqvZ3vGoGs0

looks like a good watch

[sweet loom]

Imma watch tjis

[bright coral]

there are millions of libraries around the globe, each one has a purpose, from sound designs, to assets creations, to world generations and millions or even BILLIONS of other seperate stand alone uses and each and every one depends on your project and what it's about...

[sweet loom]

Ummhm

@bright coral @real peak thx for the help guys

[bright coral]

Sure thing

[real peak]

good luck

[rose heart]

Anyone like this little game that I made?

confirmation = input("Would you like to play a game? (yes/no) ")
running = True
if confirmation.lower() == "no":
    print("Ok...maybe next time :(")
    quit
elif confirmation.lower() == "yes":
    print("Ok, let's get right to it!")
    number = input("What number do you want someone else (or yourself) to guess? ")
    while running:
        print("I am thinking of a number...can you guess what it is?")
        print("(If you want to quit at any time, just click 'q')")
        guess = input("Guess: ")
        
        if str(guess).lower() == "q":
            break

        elif float(guess) < float(number):
            print("Higher! ")

        elif float(guess) > float(number):
            print("Lower! ")

        elif float(guess) == float(number):
            play_again = input("You won! Would you like to try again? (yes/no) ")

            if play_again.lower() == "yes":
                print("Ok, let's play again! ")
                continue

            elif play_again.lower() == "no":
                print("Ok...I hope you had fun!")
                break

[dawn quiver]

@rose heart It's fairly simple but neat! Maybe you should add an option of the computer generating a random number (cuz I have no friends 😣)

[rose heart]

Nice recommendation, but I don't exactly know how to do the random number generator thing. And also, do yourself a favor and go outside and socialize man

[dawn quiver]

A bit hard during lockdown 👀 and I'm quite introvert 😕 py import random x = random.randint(min, max)generates a random number but the maximum is excluded so if you use random.randint(0, 10) the number will be 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9, not 10

@rose heart

[rose heart]

Nice to know

[dawn quiver]

I hope you find programming as fun as most people here, have a great day! 😄

[rose heart]

Thanks!

[last flare]

ofc programming is fun wdym 😄

[dawn quiver]

He seems to be new to Python, I hope he's enjoying it as much as we all do

[last flare]

ah thats actually great!

[frozen knoll]

Don't forget, if you are looking to program Python games, check out https://arcade.academy for ideas.

[real peak]

I'm creating a text-based RPG, it would be a good idea to create a class called enemy with attributes health damage name armor description and so on right? Or does this seem misguided?

And then create objects for each individual enemy type based on that class, for example object goblin

would you guys do this or take another approach? Perhaps create a huge dictionary for enemies?

I'm also curious if the object oriented approach would be applicable for the player, so that player.health and player.name could be referenced in the same way

sorry for word vomit

[tranquil girder]

Yes, it's good idea

[normal silo]

@real peak There are a couple of different methods, but one really simple one that can be used for many games is having "Game Objects" or "Entities" (I use the latter term, while Unity uses the former) that exist in a "World". So a really simple solution is to have a "World" class that holds a list of "Entities", each entity is an instance of the "Entity" class. The Entity class contains a reference to the World that it exists in (passed to it through the constructor, an Entity cannot exist outside of a World). Each Entity also has two methods update or tick and render or draw. The former handles the game logic of the Entity while the latter renders/draws the Entity. The World has a couple of methods that let you add, get, and remove entities, and also update and render, which just calls the update and render of each Entity in the world. So now that you have this structure you can make a Player which inherits from Entity. Inside the Player's update method it can handle player input, move the player, etc. How does one Entity interact with another Entity? That is where the reference to World comes into play, Entity's can query for other Entity's by name, type, etc through the World's get_entities_by_name or get_entities_by_type methods.

This method also let's you work in a group since different people can each just make their own Entity and add it to the World.

A few recommendations to go with this structure is that you should double buffer your World. That is, when an Entity's update is called it returns a new Entity rather than modifying itself. These new Entity's are put in a new list that is the new state, while you still have the current state from before. Then the current state becomes the new state. Another recommendation is that Entity's should not edit the values of other Entity's, but only themselves (unless you have to). For example, if you had a Bullet and a Player, rather than the Bullet detecting collision with the Player and then subtracting HP from the Player, the Player should instead check for collision with Bullet and subtract HP from itself (self modifying). But again, update should return a new Player that is the updated version (that took damage). Also since you have this double buffering system in place you could also store the last N states for things like undo (if your game needs an undo functionality).

Since you are doing a text only game you may not need the render method and the World's update would be called after each input from the terminal and query for the Player and give it the input.

[jagged crown]

In Unity, Does anyone know how I could make the below app UI such that the user can pick and drop predefined building assets from a drawer into the world?

I'm trying to make it somewhat of a self world builder game...

[real peak]

This is no doubt extremely good info, thank you! That being said it might be more applicable for others who are dealing with graphical games with persistent worlds, with entities within them, each with their own kind of behaviors

Such as pretty much any game made with Unity

I have some experience with modding Minecraft so I absolutely understand the importance of defining World classes and loading Entity's within them

[normal silo]

There is nothing stopping a text-only game from having a persistent world with entities in it (it could probably do this better than a graphical game because you can spend all your computation budget on stuff like AI).

It's a very generic system, you don't have to use it in a sandbox / simulation-ish way.

It's really just a way to store your game state (which all games have), and a framework for various things in the game to interact with each other (the World serves as a communication channel between Entity's).

Take for example a non-simulation-ish game: chess. You could have a couple of entities: Player (holds input), Board (holds the board state (list of pieces)), Piece (a chess piece base class), Knight (inherits from Piece), etc.

If your game is very story focused I recommend also having a scene system. The scene system can tell the World various commands, like "clear all the entities and then create all of these new entities" (set the stage). This scene system has a Director which holds of a list of Scene's. Each Scene has a enter, update, and exit method. The Director calls these methods when the game enters a new Scene (enter), exits the Scene (exit), or is still currently in the Scene (update). Each Scene also has a reference to the World so that it may issue various commands on enter, exit, and update. The Director has methods like transition_scene which takes a new Scene to transition to. The current Scene then has its exit method called and the new Scene is passed as an argument so the current Scene knows what the next Scene is (to allow for the correct transition logic to take place).

You can either have this system be its own separate thing or have Director (and even Scene) be an Entity.

In this system Scene's can be developed separately like Entity's so it works well for groups too.

[real peak]

Thank you very much. This is golden info so it'll probably take me a couple days to internalize everything you said haha

I absolutely want to set my project off on the right foot so I'll follow your advice as closely as possible

[normal silo]

You can actually get away with just the scene system and not the entity system and just store the state manually as is needed for each scene, but your code will start to become a mess if you try to add more stuff later or just make the game bigger in general.

The World is the glue that holds all your hacks together.

Without it your game has no skeleton (for very simple games this issue is not noticeable. It becomes extremely noticeable if you work in a group).

[gilded grove]

hey guys

can someone explain why pygame keeps getting highlighted in VSC when i already have a path w python 3.7.7

[potent ice]

Maybe something like this? I think it all boils down to you using conda and there are some hoops you need to jump through : https://stackoverflow.com/questions/63376024/vs-code-intellisense-not-working-with-conda-python-environment

maybe you also have an old version of conda. It seems weird that 3.7 is default etc

[gilded grove]

what is a language server?

i googled it and i still don't know what it means

i don't know how to select it in VSC i tried googling

[potent ice]

https://code.visualstudio.com/api/language-extensions/language-server-extension-guide

You can for example install the PyLance extension and see if that works better. It's a different language server for python

[gilded grove]

the thing is

i don't even know if the game is affected by these red underlined things

bc the players still move...

[potent ice]

They are not affected by it

[gilded grove]

and the birdie still has physics

it just bothers me ig

i think i can leave it alone

[potent ice]

Install pylance instead

It's an extension

[gilded grove]

i'm confused

i scanned the website you sent

it doesn't say how to install pylance?

i command F'd it too

uhhhhh

what?

[fathom garden]

can someone help me, I'm trying to make it so the scores on the right will be displayed in order of top 6. I have been stuck for a couple of hours now. Thx

[sweet loom]

I donno

Only 1 week experience sorry

[gilded grove]

do you know any good videos for sprites? i'm confused

[sweet loom]

Wait

Sprite is useful?@gilded grove

[gilded grove]

yes that's how you animate things

based on my limited understanding

so this is my badminton game right now

the birdie bounces off the blocks

i want to change these blocks to people

and when it hits the racket the birdie flies back

[sweet loom]

U can use simple assets

[gilded grove]

what's a simple asset

[sweet loom]

Lemme give u link in dms

[gilded grove]

thanks dude

[sweet loom]

Like from a site

[gilded grove]

much appreciated

[sweet loom]

Gave u in dms

[gilded grove]

ok i'm still confusion

i can't do sprites bc there's no images in motion

and i can't do assets bc there are no players w badminton rackets..

can i modify an asset to include a badminton racket??

ugh i really should have thought this through

game dev is damn hard

[potent ice]

Take one thing at a time. There are lots of pygame resources out there.

[gilded grove]

yeah but like

What can I use for pixel art?

[potent ice]

Draw something quick and dirty yourself or find existing assets out there

I find it easier to just draw something quick and ugly myself 😄

Optionally just draw everything with shapes/rects

Why not? 😉

[dusk dew]

Wow that's amazing

[dusk dew]

Wdym but why? Pygame is good

[oblique aspen]

no, i know but what possessed this man to make something this amazing

this competes with older versions of sonic (in terms of graphical quality)

[potent ice]

Maybe now game related, but at least graphics/audio/media related: A Brazilian producer created a real-time music visualizer in python. It's using moderngl for rendering and the soundcard package to analyze audio + ffmpeg to decode video. This is the very first working iteration I think : https://www.youtube.com/watch?v=H3uXtLWQN8Q

Might give some inspiration at least. There so much fun stuff you can do with audio.

Music and everything created with open source tools

.. and it shows that you can do pretty heavy stuff in python if you put in the work

[potent ice]

I think the old version of the project used 1 hour and 20 minutes to render out a video. Now it's pretty much realtime 🙂

[sweet loom]

Do anyone know how big games like valorant,csgo,cyberpunk 2077,or others big titles how they are made

...

[ashen flame]

can someone help me?

[potent ice]

@sweet loom They are usually made with a custom game engine specifically made for the type of game they are making. Often hundreds of people work on these systems for years. It's pretty insane. Even if they use some external engine there is a lot of customization and tooling needed to produce the type of game they are aiming for.

[potent ice]

Don't call your script "pygame.py"

Python will believe your script is pygame itself.. at it's correct that your script don't have an init function

Also don't put scripts in the .vscode dir 🙂

[ashen flame]

owh ok

thank you

[bronze shell]

when i run it shows black screen and when I quit it shows the background and then quits

[maiden marsh]

why does this not work py import pygame start_ticks = pygame.time.get_ticks() #starter tick mainloop = True while mainloop: # mainloop seconds = (pygame.time.get_ticks()-start_ticks)/1000 #calculate how many seconds if seconds>10: # if more than 10 seconds close the game break print (seconds) #print how many secon

[severe saffron]

what are you expecting

i think you might need to do pygame.init for that to work

[sweet loom]

People use comments

Pointless isn't it

[last moon]

how so

[sweet loom]

Just takes writing time

And ur writing what u thinking how does it help

[last moon]

fair enough for simple code you have a point but for a complex program you might not be able to remember/want to waste time trying to figure out what a snippet does

• just because your code is clear to you doesn't mean it's clear to the people you're sharing it with

[sweet loom]

Hmmm

[last moon]

imagine working with a library that doesn't have any docs

[sweet loom]

Hmm

[last moon]

regardless this isn't a game-dev topic

[sweet loom]

[last moon]

@potent ice got a min to talk?

[potent ice]

Maybe. What's up?

[last moon]

i've started digging into arcade but im a little unclear as to when I should actually be using arcade.gl

[potent ice]

It's there in case you want to do something custom really. Definitely not the first thing you start with.

There are examples in the experimental directory

There's not much documentation available for it, so ideally right now you need to know some OpenGL. That will probably change in the future.

However.. if you start to play around with arcade.gl examples you'll at least see the power it provides

It's a super power that can be unlocked in the future 🙂

[green relic]

What is the innit function for?

[upper pawn]

hi

[bright coral]

Yo fellow dream fan!

[potent ice]

If you are referring to __init__ that is an initializer for a class instance... OR are you talking about something else? Maybe pygame.init()?

[green relic]

both...

Im new i dont know how many there are

[potent ice]

You can look up functions in official documentation 🙂

Search for init here for example : https://www.pygame.org/docs/

Then click the relevant search result and read what it says

For __init__, this is something you'll know after learning classes

Don't attribute anything magical to these methods. They just are.

[green relic]

screen.blit(backgroundSurface,[0,0])
screen.blit(peopleSurface,[0,0])
pygame.display.update() # Update screen

It will only show that 10x10px image and everything went black. But if i remove that second blit it will work normally but without that people Any idea ?

Anyone know of any good videos that teach basic game code?

I can create a janky simple 2D platformer or a basic text adventure no problem. But I'm stumped as how to create a persistent "world". Could a 2D world be represented with a 2D array? What about NPC spawning? Are NPCs instances of an NPC class?

These kind of game design questions are what I have and I'd love a walkthrough of this stuff

In short, I guess no-engine game design for people who already have a fairly ok understanding of code

[last moon]

So persistence comes with using classes/objects and being able to save/load game states - what and how you save/load depends on your game and such but it could be as simple as saving a class’s attributes to a dictionary and writing to a json

A 2D world coulddd be represented by an array but it really depends what you mean by that. You could have your map stored in chunks in a multidimensional array or have aspects stored like that

NPC’s can be instances of the same class but you can run into performance issues if your class does too much (ie Yandere Sim)

[last moon]

I’ve heard DaFluffyPotato’s vids are great but https://learn.arcade.academy/ is a great resource too

Also iirc pixels are stored in an 2D array (tensor?)

[potent ice]

Pixels are definitely stored in a 2d array, but in most cases this is not something you interact with much (directly)

Game objects probably just have a x and y location in 2D

It can be useful to have a spatial hash for your game objects. That is often the key to wiring 2d games that performs well.

[real peak]

Thanks lads

For 2D array I was thinking more locations in terms of a map...
[T][R][0][0]
[0][R][R][T]
[0][0][D][0]

T is town, R is road, D is dungeon, something like that

Then to "move east" you advance x index of array by 1, to "move south" you subtract 1 from y index

Idk if I'm wasting my time or if this is conventional

obviously python arrays don't look like that but yeah

[potent ice]

I think this depends on what kind of features the game/graphics library has

If text and cell based you can of course do this.

Arcade has "sprite lists" what will just batch draw lots of image. pyglet has sprites and batches. pygame has sprites and sprite groups.

You can make tile maps with arrays like that at least 🙂

I would not obsess too much about data structures before you explore the game/graphics library you are planning to use.

If you are making a simple snake game the array can make sense

[real peak]

Text-based RPG, just using Kivy as a GUI for buttons/inventory/icons

This series is really good

It also implements a lot of features specific to the terminal and isn't very generalized. Still, if anyone's in my position it's worth checking out

[shy cairn]

def enemyRect(posX,posY,x,y,z):
	red = 255,0,0
	pygame.draw.rect(screen,red,(posX,posY,x,y))

while run:
	for event in pygame.event.get():
		if event.type == pygame.QUIT:

Problem: It's only spawning one enemy instead of 5 enemies.

[fringe dagger]

hey guys question

whats different in pygame 2 from the previous versions?

[potent ice]

You can read the updates notes here : https://github.com/pygame/pygame/releases

[fringe dagger]

ah so all of the documentation still follows the 1st version right?

[potent ice]

According to the release notes it should be backwards compatible at least. There are some new stuff and optimizations. So many changes it's not really something that can be summed up here.

There are really no reason to use pygame 1.x now. That's about it.

How to draw rectangle with class(sprite) ?

[plain drum]

Hello all, I have a question that I can't find the answer to. I am currently working on a game that uses PyGame and OpenCV. I am trying to apply multi threading to the game so I can run PyGame window and OpenCV window at the same time. But what happens is that when I start the thread either pygame or opencv windows freeze and program says it cant respond. So I either have to force quit or wait it out. If someone knows a solution or is willing to help me with this project I would be really grateful. 🙃

[potent ice]

I bet it's something with OpenCV. I have heard about a similar issue.

[plain drum]

Might be, I am trying to figure it out. Will update when I find a solution.

does anyone have tips for coding a first person game

[plain drum]

As long as I know it is not common to use Python for complex games such as a first person game. I think you can use pygame but it is going to be really hard and.

You can try using unity with C# if you want to create a game like that in my opinion

[empty ivy]

How do I make a caamera in pygame?

[plain drum]

You can try something like this

mport pygame
background_colour = (255,255,255)
(width, height) = (300, 200)
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('Tutorial 1')
screen.fill(background_colour)
pygame.display.flip()
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False

to create the window

or follow this example https://www.petercollingridge.co.uk/tutorials/pygame-physics-simulation/creating-pygame-window/

after you create it you can draw on the canvas or import npg's

I don't think there is a camera object in pygame like in unity

@crisp junco you had any luck with the code ?

[empty ivy]

not creating the window, like the scnece following the player

https://youtu.be/Rvcyf4HsWiw

[finite badger]

ok thankyou

[normal silo]

This is an OS thing, you can only have 1 window per process unless you put in some extra work, and basically all your code needs to be aware of there being multiple windows and the window events need to be juggled between threads / parts of your code. Pygame and OpenCV don't know of each other's existence and assume that they are the ones to get all the window events sent to the process (this is a guess, idk what their internal code does, but it's often the case / an assumption made by libraries that use windows, they are selfish in that way).

There is a hack for this and that's using multiple processes instead of threads.

But if you want fast data transfer between processes you will have to set up a shared memory buffer. If not, it's pretty straight forward, use the python multiprocessing lib, and setup pipes between them.

[ancient warren]

working on a text based game again, currently working on getting all the functionality and structure into place

all of this makes it so that essentially when a question is asked, if you dont answer one of the yes or no answers, it makes you answer again until you do at which point it returns 1(yes/true) or 0(no/false) to simplify it so i dont need to do a ton of if/else loops later on

i could probably do it more efficiently, but I'm just getting the framework in

[real solar]

could i get an example

[tranquil girder]

what is your use case exactly?

[real solar]

i have a button called start

from ursina import *
app = Ursina()
window.color = color._20

main = Entity()
button = Button(text='Start', color=color.azure, scale= .200)


def button_click():
   print("heya")
button.on_click = button_click
app.run()

and when i click it

i just want to go to another screen that has another button that says yay!

[tranquil girder]

just disable the start button in your button_click() and enable the other button

button.enabled = False
other_button.enabled = True

[olive parcel]

It might be easier if you wrap the code to create and destroy one screen in a function or class, so you can more easily recall that screen

[vague flame]

why "IndentationError: unindent does not match any outer indentation level " in python 3 "IndentationError: unindent does not match any outer indentation level " in python 3

this is coming why?

[tranquil girder]

the last two lines starts with a space
also make sure you're not mixing spaces and tabs

[potent ice]

I see a lot of people using notepad and notepad++ having this problem!

notepad I would not recommend... and I don't know if notepad++ is good at formatting python code.

I think both atom and vscode are better alternatives than this.. and maybe even sublime

[olive parcel]

They're all three good editors, sublime being significantly less resource-intensive than the other two (due to not being written in HTML/JS)

[dawn quiver]

@potent ice vscode is definitely the way to go. Especially if you're a beginner. Notepad is just going to make it take 100 times longer to learn proper syntax an with python indentation as well.

[potent ice]

Sublime is amazing for huge files. Atom is the worst for huge files in my experience. (I mean HUGE)

[dawn quiver]

I would use Sublime but I'm still new to a lot of this. I dabbled in CSS, HTML, and some Javascript when I was younger. Just now getting into actual programming.

So, I find it best to stick to one IDE an learn the ropes without all the back an forth confusion.

[olive parcel]

They're pretty similar, but overall VS Code is the better product, I'd say—Sublime may be worth it if you're struggling with the performance of VS Code.

They both have all the cool new features like multi-caret editing.

[dawn quiver]

Hey! How long did it take you to develop Panda3D?

[olive parcel]

I did not develop Panda3D

It was created by a team at Disney.

[crisp junco]

Ah , I see

[potent ice]

Iterate.. iterate.. iterate for years I guess 😄

[blissful depot]

Is ursina good?

Also, I'm a bit confused with pygame animation

[normal silo]

Notepad++ is excellent, you can also show invisible characters in notepad++ to make sure that you are not mixing tabs and spaces, there is a button for it in the tool bar (toggles invisible character visibility).

There is also a convert all leading spaces to tabs and the other way around.

[normal silo]

See scene in the ursina cheat sheet. You can do scene.clear(). You can use this function to build a scene system that transitions between scenes.

[mystic lodge]

is there any way to compile your python program with modules like pygame (not using pyinstaller)?

[potent ice]

cython?

not 100% sure what you mean

[potent ice]

I like np++, don't get me wrong. I just see a pattern that beginners using it struggle with indentation. Could also be related to cut and paste from other sources.

.. or how np++ handles pasted content? no idea.

[crisp junco]

Though pyinstaller is the best you can still try auto-py-exe py2exe cx_Freeze etc.

[normal silo]

AFAIK the default setting is just to directly copy paste, not modify anything pasted. There is an option in Notepad++ to automatically convert all tabs to spaces.

Ultimately the problem is that an invisible character is part of the language's syntax (if a beginner does not see it they won't focus on it, it's natural to assume non-visible things don't matter / requires some extra mental work in which one needs to already understand the structure) and that not all editors will make assumptions about what you want to happen when copy pasting (some users may find that annoying and have to disable it).

(Nor do all editors provide indentation guides)

i have this code and it has to ask for your profesion and if its warior than print it but it doesnt work and it doesnt give any specific errors... does anyone know what i can do?

[worldly flare]

I wanna make a dungeon generator similar to that is binding of isaac and I wanna code it in pygame for my game but I tried various methods but they dont seem to work so how can i make one

please help me out

I am fustrated after several attemps

[worldly flare]

are you getting more functions from another python file?

[edgy slate]

no i guess?

[worldly flare]

what about using time.delay instead of time.sleep

and also are you writing the code inside the main loop?

[edgy slate]

nope and the program doesnt get past the "if" part

[worldly flare]

what kinda game are you making? could you please help me with a dungeon generator?

[edgy slate]

im just making my own eddition of dingeons and dragons

[worldly flare]

hmm.. quit nice

so is it graphic based or console?

are you gonna make any dungeon generation algorith stuff?

[edgy slate]

its just a "text" game not mutch, like it writes a situation and gives options

[edgy slate]

and no idk how to do that

[worldly flare]

hey,so I am more like a pygame guy so..

[edgy slate]

i could try to learn that rl quick but i dont think ill need that in the future

[worldly flare]

I cant help much

[worldly flare]

yeah right

[edgy slate]

couse i mostly program raspberry

like motors and sensors

[worldly flare]

seems quit interesting

well, I use to develop games

[edgy slate]

i know but theres alot of wirring and for a break i tfought ill program a little game

[worldly flare]

you should try a graphic library for game dev

you can make games with graphics

[edgy slate]

k ill try someday

and do you mean this by generating dungeons?

like automatic generation?

[worldly flare]

yup

that is it

[edgy slate]

but saddly i have 0 idea how to do this...

[worldly flare]

I think its not gonna be too tough I could do that but it will take too much time to do so

hence I thought of seeing some codes by the others

to get an idea

[edgy slate]

but like you can make def chamber1() and on screen do like 20% to chamber1 and have multiple chamber and than just ptogram paths that connect chambers

[worldly flare]

of how it works

[edgy slate]

i dont think it would be hard

[worldly flare]

yeah,right but if you know about the game binding of isaac I want someting similar to that but doing this will not do so

[edgy slate]

egh idk im just going to go back to my problem solving now bye

[worldly flare]

ok bye

[mystic lodge]

yes but i am on linux

                time.sleep(3)
            while aging > 0:
                screen.clear()
                #table()
                #screen.addstr(2, 7, character, curses.color_pair(3))
                #screen.addstr(3, 12, profesion, curses.color_pair(3))
                screen.addstr(4, 12, age2, curses.color_pair(3))

this is a curses screen code that has to ask for your age and than if its age from 1 to 100 it prints it, but it doesnt get past the if part... does anyone know how to fix that?

[potent ice]

Add some prints to see what is happening maybe?

if 20 < age > 40: is the same as if age > 40. It this what you are trying to do?

Good old print() or run with step debugger makes it easy to discover your mistakes/bugs

You can also test things quicky in repl ```py
$ python

age = 19
20 < age > 40
False
age = 30
20 < age > 40
False
age = 41
20 < age > 40
True

So I'm making a class to handle movement + which sprite is being drawn but it feels a bit redundant

class Controller:
    def __init__(self):
        self.up, self.down, self.left, self.right = False, False, False, False
        self.directions = {"up": self.up, "down": self.down,
                           "left": self.left, "right": self.right}
        self.move_dict = {"up": (0, 1), "down": (0, -1),
                          "left": (-1, 0), "right": (1, 0)}

    def set_sprite(self, direction):
        pass

    def move_player(self) -> tuple[int, int]:
        x, y = 0, 0
        for direction, move in self.directions.items():
            if move:
                value = self.move_dict[direction]
                x += value[0]
                y += value[1]
        else:
            return x, y``` My idea was to sort of queue up the directions rather than check them separately to handle the user pressing more than 1 key at the same time but I've got a feeling im approaching it wrong
```py
    def on_key_press(self, _symbol: int, _modifiers: int):
        if _symbol == arcade.key.ESCAPE:
            arcade.close_window()
        if _symbol == arcade.key.W:
            self.player.controller.up = True
        elif _symbol == arcade.key.S:
            self.player.controller.down = True
        elif _symbol == arcade.key.A:
            self.player.controller.left = True
        elif _symbol == arcade.key.D:
            self.player.controller.right = True
    # opposite for release```

hello everybody. I'm working on a Python program that generates road maps for use in a (non Python) game project.

Hi

Does anyone here know how to use turtle to create a snakes and ladders board game?

Help would be appreciated a lot 🙏

[real peak]

I'm a noob myself but if I were to tackle chess I'd probably create an 8x8 array

And create class Piece with child classes for each type Knight, Rook, etc.

Then instantiate them at their proper array coordinates

And add their moves as attributes based on the array, for example pawn if ChessPiece in array x,y+1 then pawn cannot move unless ChessPiece in array x-1,y+1 or x+1,y+1 (in which case it can capture that diagonal piece)

Just my thoughts on it, probably way too complex for me

game_background(1000,1000,"Cell",Plant.jpg)

[pseudo cape]

You need to first get the image

And store it in a variable

Pygame has it's own thingy

Then you need to just put it in

@ruby flame

I think

[ruby flame]

okay

[pseudo cape]

background = pygame.image.load("Assets/background.jpg")

then inside the main function you can put

window.blit(background, (0, 0))

then update the background @ruby flame

[ruby flame]

is this right? py def game_background(X,Y,pygame_caption,game_image,): window= pygame.display.set_mode((X,Y)) pygame.display.set_caption(f'{pygame_caption}') background = pygame.image.load(f'{game_image}') white = (255,255,255) while True : window.fill(white) window.blit(background, (0, 0)) for event in pygame.event.get() : if event.type == pygame.QUIT : pygame.quit() quit() pygame.display.update()

[ruby flame]

hey @pseudo cape is this right? py def game_background(X,Y,pygame_caption,game_image,): window= pygame.display.set_mode((X,Y)) pygame.display.set_caption(f'{pygame_caption}') background = pygame.image.load(f'{game_image}') white = (255,255,255) while True : window.fill(white) window.blit(background, (0, 0)) for event in pygame.event.get() : if event.type == pygame.QUIT : pygame.quit() quit() pygame.display.update()

[pseudo cape]

ye

do you have a variable called background?

with the image loaded

you can also put it outside the loop if you want

[loud fossil]

E: I'd like to get some thoughts on this.

I've recently been thinking of adding support for music cross-fading into a game engine I develop that uses Pygame as a backend. pygame.mixer is definitely insufficient for this; it only supports a single audio track at a time. So I've been searching for an alternative.

The best idea I've come up with is to jump on the OpenAL train (I'm pretty sure OpenAL supports multiple audio streams, please correct me if I'm wrong), and I've noticed that OpenAL has historically been a bit fragmented on Python. So far it seems the best candidate for an OpenAL binding is this: https://pypi.org/project/PyOpenAL/ which hasn't been worked on in over a year now, and all of its releases are marked as pre-releases. But I don't know for sure what to think about that.

What I'd like to get thoughts on is, is this or some other OpenAL Python binding something which is production-ready and which can be relied on? I'd also be curious if there's other possible ways to support playing multiple music streams at once that are suitable for dynamic use in a video game.

[pseudo cape]

ive heard of it but i have no clue on what it is

[loud fossil]

E: OpenAL or music cross-fading?

E:Music cross-fading is just fading out one music track while fading in another at the same time.

[potent ice]

You can also try pyglet's Player. You can use that with pygame if calling pyglet.clock.tick() between frames so audio buffers are updated. It supports different backends depending on platform. What backend is used is also configurable.

There is also https://github.com/McSinyx/palace, but that was archived not long ago. Never tried it

It doesn't seem to have wheels for all platforms in pypi hmm.

[loud fossil]

E:Hm, Pyglet eh? That's an interesting option especially since I've seen someone post a way to hack Pyglet video playback support into Pygame...

[potent ice]

yeah they can definitely be mixed

The same way you can use pygame mixer with pyglet project

There is also a pyglet discord : https://discord.gg/QXyegWe

[mystic lodge]

is there a pygame one lol?

[loud fossil]

E: There's some fragmented landscape for Pygame Discord servers, but I had to leave the one I was on (which is the larger one) because of transmisia and ableism.

[whole coyote]

Yes.

This is a good approach for a tile map.

[topaz raft]

and

can i use random module for may infinit levels @whole coyote ?

[whole coyote]

I'd probably look into something called perlin noise, where it's a way to create randomness in a nice way, but yes.

[topaz raft]

ok

it makes game laggy as other levels are played

[whole coyote]

I'm not sure what you mean.

Your tile map is a look-up table, it should not be laggy.

[normal silo]

They are probably looping over all tiles and drawing all of them when they should only be looping over/drawing those in/around the camera view.

That really depend what library you are using to draw them

[normal silo]

Yes and how complex each tile draw is.

Other than those 2 things idk how this could be laggy, the map does not seem too big.

(Unless they have a very slow computer)

[potent ice]

No idea how heavy a 400 tile setup is (if pygame)

[last moon]

actually perfect timing I was just going to ask about maps
if I use a tile map but want it to be bigger than the window, how would I go about choosing which tiles to draw?

[potent ice]

Each tile has a fixed resolution so it's easy enough to calculate

Again, this is assuming you use pygame. The approach would be slightly different in other libraries

[last moon]

so smthing like #of_vertical_tiles = window.vertically_oriented_dimension // tile_height +/- camera_y_offset?

[normal silo]

the number of tiles does not depend on the window position, only its size

[last moon]

that's what I meant sorry

ive been working with vectors for the past 4 hrs I can't think properly 😄

[normal silo]

(well it could, but simplify)

[potent ice]

window.width/height more accurate I guess 🙂

[normal silo]

it's just width // ts and height // ts to get tile area

plus 1 or so because the camera can be centered on the edge of a tile

[potent ice]

I think most people having their own "game engines" also divide tile maps into chunks (as far as I have seen). Let's say 16 x 16 is a chunk

render each 16 x 16 section into a separate surface so you can draw those instead

[normal silo]

chunks would just make it more complicated, you need to know which chunks a camera is in and touching.

[potent ice]

It's pretty much the same logic though

[normal silo]

yea, just grid of grid

[potent ice]

Then you have more cpu time for other game logic at the very least. Maybe a "premature optimization" thing to start with 😄

[normal silo]

chunks are more of a memory thing

[last moon]

Don't chunks help performance more when dealing more with generation?

[normal silo]

The entire world may not fit into memory or be much bigger than wanted

[potent ice]

You only keep the chunks near camera alive

[normal silo]

It's a memory thing, the performance gains comes from the ability to freeze or run more simple code for entities in chunks that are not near you.

[potent ice]

That is also true, but that's more a spatial hash thing. I guess the ideas can be combined

[normal silo]

For example, enemies in loaded chunks will perform A* search to the player, but those in chunks not loaded could be just slightly moving around or not at all.

(Or some other "off-screen" simulation logic)

[last moon]

how does a game like mc manage it tho? I'm assuming they don't load the whole map into mem but it's also not regenerated?

[normal silo]

they load the chunks near the player

Some chunks can be forced to stay loaded with mods (or exploits)

For example, automated farms will not run in unloaded chunks, so exploits are used to keep their farm's chunk's loaded so they can go somewhere else / not be online and it will still run.

[last moon]

haha ya I've spent too much time on the game to not know how that works

are they loaded into mem + drawn at the same time tho?

[normal silo]

Drawing is a separate thing.

Standard optimizations are used for that, like not drawing off-screen things.

[potent ice]

The algorithms for reducing what is drawn in minecraft is pretty fascinating

Been trying to replicate it for a while

In python that is.

[last moon]

you happen to have any links/vids on how it's done?

[potent ice]

There are some videos out there doing a decent job, but it doesn't cover everything

Some things can be deducted from reading https://minecraft.gamepedia.com/Chunk

but in order to make to render fast there are a lot of clever tricks.

[last moon]

Ill have to take a look at it later, but that's one thing I've found from watching people making mc clones with custom opengl engines, they never seem to cover what's actually going on with the renderer or if anything they'll just gloss over it

[potent ice]

Yeah or they make a small 8 x 8 chunk map.. or reducing the height

or they don't show block removal / add

[last moon]

ya not to mention most of them don't even touch optimisation

I just want 1 like 6 hr video going over each line of code written 😄

[potent ice]

Pretty sure minecraft is storing a bit of metadata in each chunk to make culling easier for example

Especially when it comes to visibility from neighbor blocks etc

What takes time in python is rebuilding / loading the blocks. I know terracraft do this in subprocesses : https://github.com/XenonLab-Studio/TerraCraft

but it's a fairly small map with only a 16 x 16 x 16 chunk size

Me and Leterax have been tying to do chunk rebuilding and reduction on gpu in the last year. I think iteration 3 or 4 atm

(Without compute shaders that is)

[normal silo]

You need a C module to have fast enough chunk generation, python is not suited for this kind of task.

(could use cython)

Probably want some multi-threading too.

[potent ice]

Started on a C++ module, but it was more fun to use gpu

[normal silo]

If you want to use the gpu with a compute shader you can use use either kp or pyopencl.

https://pypi.org/project/kp/

You can create shaders in python (converts python byte code to spirv)

(Used for ML)

[potent ice]

Just used moderngl for now. Shaders can be moved to vulkan later if needed (they are basically the same).

[normal silo]

Yea, just with this you don't need to do any c++.

[last moon]

that's the fun part tho

[normal silo]

I do not consider opengl "fun".

[potent ice]

Well. I don't use any C++ if I use moderngl that is 😉

[normal silo]

Graphics is fun, but opengl is a mess.

[last moon]

lowkey I almost tried starting with vulkan the other week

not a good time

I couldnt even get it functional

[normal silo]

Vulkan is mocked for requiring 1000 lines for a triangle or something like that. Ideally someone creates a higher level framework similar (but much better) to opengl with vulkan (open source).

[potent ice]

Vulkan do have so many advantages over GL. That is true. I would never today try to do anything 3.3+ with pyopengl

[last moon]

I knew it was lower level than opengl I just didn't realise how much work has to be put into it
not to mention the struggle of c++ on windows

[normal silo]

A bunch of projects are still WIP with OpenGL, it does not make sense for them to switch now. But in the future yeah.

[potent ice]

Definitely

Also another vulkan project : https://github.com/cprogrammer1994/glnext

[normal silo]

Though I think some open source lib based on vulkan will come along that blows up in popularity, there are several WIP.

Including a re-implementation of OpenGL, which might seem pointless, but it's actually better because OpenGL is normally so hard to debug.

And if it just works as a stand in, existing projects could use it.

But everyone might just abandon OpenGL instead and use Vulkan on their next projects.

[potent ice]

The ones who can, definitely

[normal silo]

Either way Vulkan is facing the same issue as OpenGL, which is that Mac and Windows are trying to force their own APIs (metal / DX)

[potent ice]

Yeap ...
