cool

[dawn quiver]

Oh man I always loved gravity puzzles

They are like truly the best

I'm planning on creating a game related to space and time

[short tapir]

insane

[shell scroll]

thank uu!! and oo sounds fun u should!(:

[scarlet lake]

might be too late now, but you should ask for user input, and use if statements and some math to produce results.
an example:
money = 4850
level = 1
question = ask for user input
if (question == "yes")and(money>=200):
while (question == "yes")and(money>=200):
money = money-200
level = +1
print("Level is now", level)
print("Gold left:", money)
question = ask for user input
if question == "no":
quit

Now, this most likely isint the most efficient, and if you are looking for perfect efficiency with no possibility of anything going wrong, there are better ways that this. however, this should work 👍

[orchid zinc]

Hello! I'm currently rebuilding an ECS project of mine with the intention of significantly enhancing the codebase's stability and ease of use. I wanted to get some input on what I'm currently thinking about how the interface for the package should work.

The basic idea is that entity and component setup should be simple and accessible. In the past, I had enabled the user to access a component on an entity by passing in either a string corresponding to the component's class name, or by passing in the component's class symbol itself.

For this version, I wanted to make this simpler and much more robust, so I have the following initialization patterns supported:

engine = Engine()
world = engine.create_world()

zombie = world.create_entity()
zombie[Position] = Position(10, 10)
zombie[Velocity] = { 'x': 10, 'y': 10 }
zombie.add(Health, { 'maximum': 100 })
zombie.add(Name(value = 'Bob'))

Does this sound reasonable? And/or are there any obvious drawbacks to any of these methods? I'm happy to provide implementation details as well.

Note that once components are added to the entity, they can be retrieved either through the class symbol (e.g. zombie.get(Position) or zombie[Position]) or through a string corresponding to the class name (e.g. zombie.get('position') or zombie['PoSITiOn'], etc.)

[grim abyss]

is zombie[Health] = 100 valid for your ecs api ?

[orchid zinc]

No, you would define methods for manipulating component state.

[grim abyss]

I see

[orchid zinc]

Components are defined ahead of time, inheriting from a component base class

[grim abyss]

and zombie[Health] = zombie.add(Health, {'maximum': 100}) is valid I'm assuming ?

[orchid zinc]

add doesn't return anything, so no. That could be implemented though, probably

[grim abyss]

is this on github?

[orchid zinc]

Not yet, but I'll be putting it up soon

[dawn quiver]

Looks great to me, that dictionary usage for coordinates pokes my heart though 😛

Also it specifiy says Velocity type.. unless that was an alias for a dictionary, which I dont think works with esper (what I use) so I may have just found it unnatural

I have been messing around with some ECS
https://github.com/blankRiot96/ecs-pygame

[orchid zinc]

Ahh yeah - esper is nice, though my components have a bit more going on in terms of configuring properties and making serialization easier

https://github.com/krummja/ECStremity/

ECStremity is the previous ECS that I developed. I'm using it as a basis for the new ECS, which should be a significant improvement over some of the messier pieces of its predecessor.

[dawn quiver]

Oh neat

[frank totem]

hi 👋 could anyone help me with my hangman game

So basically I'm not quite sure how to ouput the letters in thepygame windows

like the the length of the word

as well as a list that handles all the letters that have been used

also idk how to make my buttons work i dont quite get it

I've only managed figure out the exit button

[crimson pelican]

anyone here know how PyQt5 works

cause I need help with my QGraphicsScene not showing up

ping me when u respond to me

[orchid zinc]

https://github.com/krummja/PECS

Still a lot of work to do to get it up to a workable state before publishing on PyPI, but this is where the new ECS library will be if you're interested

@grim abyss Wanted to ping you as well since you asked about it being on github earlier

[grim abyss]

cool, gonna check it out there buddy

might even contrib...

flex those pecs...

[orchid zinc]

haha

[dawn quiver]

@orchid zinc On the installation subheader you could include pip install git+https://github.com/krummja/PECS to install with pip

The code looks great! 😄

[keen pewter]

PyGame question @ #help-potato please thanks

[desert forge]

if i were to make a menu for my game, which library can do it in a more fancy way?

[dawn quiver]

What library are you using for your game?

Oh are you asking what library to use for your game based on what can make a fancy menu

[snow hill]

https://www.youtube.com/watch?v=JqTbqwCjrEA ❤️

[desert forge]

somewhat yes

i am using pygame but i didnt really like how it makes the menu

[dawn quiver]

PyGame doesn't make a menu for you, you use it to make one

I made one recently

2 actually

[desert forge]

yes but the way its made isnt really nice

show show

maybe i am the one who isnt really using pygame as its supposed to then

[dawn quiver]

Oops that jumps into the gameplay too fast

I'll take new recordings give me a second

[desert forge]

oooo that looks really nice

the menu is really clean

if you can, could u explain how you made the menu

[dawn quiver]

The other one I made

[dawn quiver]

Thanks

[dawn quiver]

That's a very big task, and I don't feel it would help you either
What I do feel will help you is looking into pygame_gui
https://pygame-gui.readthedocs.io/en/latest/

It is what I used for the second menu, also a lot of this just comes with repeated usage and familiarity, so consistent usage will be the most helpful asset among anything else here

[desert forge]

ok

looks like there are a lot of things i need to learn to continue work on my game

[grim abyss]

https://www.pygame.org/docs/ref/rect.html#pygame.Rect.clipline

[spice lantern]

With the limit, would it be best to go by CPU/RAM limitation, or set a hard limit?

I'm assuming the landscape is procedurally generated?
are you storing unloaded chunks somewhere, or just regenerating them from the same seed each time they get loaded?
I'd recommend you do the latter, although if you want the terrain to be editable, you'll need to store modified chunks
You could just store the voxel data for modified chunks, but if you're only expecting a relatively small amount of voxels to change, you could try storing a diff between the 'base state' (what the procedural generation algorithm spits out for that chunk) and the modified state

[snow hill]

I think he did more or less that

the world is procedurally generated from a function that returns a block ID from a world position

so at first there is not need for any storage and the world is potentially unlimited

then he will start to store "user blocks" in a sparse matrix

and each time a chunk gets "dirty" the mesh is reevaluated

maybe @lyric pawn could tell us more 🙂

[true cloak]

I’m not TOO advanced in python, like i know enough to program what i have but I’m not the best. I’ve been programming a text-based battle system where the user can face off against enemies with multiple party members who have differing menu options and stuff, so basically i was just wondering if i send the code later (currently implementing something), if people could give feedback on how to improve the code and make it more efficient/less complicated?

[hardy drift]

[grim abyss]

!paste

[frank field]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[dawn quiver]

Sure, go ahead and send it :)

[true cloak]

alright i will, stopped coding a bit ago but once i finish will send

[true cloak]

this might be a bit since I’m currently in the process of quite a big overhaul

also it requires external files (just a couple txts), should i substitute in placeholder data or something?

[tame cloak]

Hello anyone want to help me with code in pygame?

[dawn quiver]

Making a repository and sending a link to that might be cleanest

[true cloak]

alright

[lyric pawn]

The world is procedurally generated and as @snow hill said, I store modified blocks and loaded chunks in a sparse matrix (in Python it’s actually just a dictionnary class with a tuple (x, y, z) as key and I reload a chunk whenever a block is removed/added inside of it

[potent ice]

That's pretty much how I do it as well. I keep track of dirty / modified chunks and save them in a fixed interval and on exit

I did use a json format initially to make things easier to debug, but changed to a simple binary format. I can convert between them anyway, so it's not aproblem.

[fierce wraith]

Yup, keeping track of dirty chunks in a dict is a great way to do it!

Are you generating the chunks in python?

[potent ice]

I'm generating chunk data in shaders currently to speed things up a lot. My chunks have 65_536 blocks so it can be a bit time consuming in python. To be fair.. it can be done in subprocesses. I just liked the speed when using shaders since I can pretty much re-generate the entire world in less than a second.

[sterile mauve]

How do I make UI?

How get tkinter package?

[vagrant saddle]

for game you would probably want an UI provided with game engine, eg pygame_gui in pygame, or direct in Panda3D, also tkinter may not be the best choice on mobile or web

[sterile mauve]

I want to make a word based game but you can press buttons

[vagrant saddle]

looks 2D so i'd say pygame

It would make more sense to remove the player bullet from whatever container you are storing it in

[rugged silo]

how to make tap on the button(example 1) --> sth happened instead of input the text --> sth happened
maybe its possible with if or while
example :

print('u tap 1')```
or
```if tap_2:
print('u tap 2')```
or even
```while u_tap_1:
sth happened always while u clamp 1```
 
hmm.....
is it possible in Python ??  ?!?!?!?!!?!?!??!!?

[dawn quiver]

What GUI framework are you using

[raven marsh]

ok, my solution is to just redraw over it, but the rect is still there, how to remove the rect?

[rugged silo]

PyCharm

[raven marsh]

ok, i found a solution, using list to remember what bullet rect has collide and wont detect it anymore :)

[dawn quiver]

def gameloop(running = True):
    shooter = pygame.image.load('shooter.png')
    bullet = pygame.image.load('bullet.png')
    x = 275
    y = 300
    bullet_x = 200
    bullet_y = 200
    x_vel = 5
    y_vel = 5
    win.fill((255, 255, 255))
    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    x -= 5
                if event.key == pygame.K_RIGHT:
                    x += 5

                if event.key == pygame.K_SPACE:
                    while not keys[pygame.KEYUP]:
                        win.blit(bullet, (bullet_x, bullet_y))

        win.fill((255, 255, 255))
        win.blit(shooter, (x, y))
        pygame.display.update()

Here, I am trying to make a shooting mechanism in my way. While, I'm pressing the space button it blits the bullet image and increases it's x to move (not necessarily x). But the problem here is it fills the screen white after it blits and moves. But I need to fill the screen white because I have a shooter image which I also want to move. Is there a way to not change anything but blit and move the bullet image while I'm pressing space?

[normal silo]

Fill the screen, then blit the bullet, then update the display.

[dawn quiver]

Can you show in code

[normal silo]

win.fill((255, 255, 255))
win.blit(bullet, (bullet_x, bullet_y))
win.blit(shooter, (x, y))
pygame.display.update()

1. clear screen
2. draw stuff on it
3. flip the display buffer (update)

[dawn quiver]

okk

[normal silo]

1. Get Input.
2. Act (on input and as time passes).
3. Render / Draw (this has the three previous steps in it).

Hi, need developers to test out PandaEditor, it's a level / scene editor for panda3d game engine, currently except for scene saving all other core systems are implemented. You can write python scripts to define object behaviors... to extend the editor with custom features there is support for editor plugins too. If you like it give it a star on GitHub, you can support it on patreon too, it would really help to speed up the development. https://github.com/barbarian77/PandaEditor

[glossy dune]

in pygame u can't just say pygame.draw because ur just accessing the module. Pygame can draw primitive shapes(circle, rectangle, line...). Or polygons defined by point coordinates. Or images/text. I think ur trying to draw text to the screen. For that u 1. have to call pygame.font.init() to create an instance of the font module. 2. load in a font by calling font = pygame.font.SysFont({ur font}, {font size}). 3. create a surface with the font and text u want by saying text_surface = font.render("win", True, {font colour}). 4. draw the text surface to the screen by saying screen.blit(text_surface, (x, y)). Hope this helped

Can someone help me, I usually know how to do basic python coding but this is difficult for me and I can't seen to complete it/do it right. Thanks in advance

[potent ice]

Might not be the right channel for this problem. The best way to approach the problem is probably breaking the problems into smaller parts. What have you written so far? Where exactly are you stuck?

A lot more people are willing to help with smaller problems. You are presenting a whole assignment here. Almost no one have time in their busy life to cover every question you have in one session. Break things down into smaller questions. Something that doesn't involve the screenshot, but is simple enough to explain in one sentence.

They are fairly high level game libraries.

i agree

[finite solar]

They were supposed to but since I was restricted in time I couldn't polish the feature enough to do so.

[earnest cloud]

anyone wanna help me derive the appropriate conditions for keeping particles in the region between these two boxes? it's really stumping me rn. the straight vertical sections on the left and right, as well as the straight horizontal sections on top and bottom aren't an issue, it's the corners of the region that have me scratching my head.

this is in c++ btw, but doesn't matter since it's only a group of if statements. this is what i've got so far (written as if it were python):

if (particle.position.x < 250):
    particle.position.x = 250
    particle.velocity.x *= -1

if (particle.position.x > 950):
    particle.position.x = 950
    particle.velocity.x *= -1

if (particle.position.y < 100):
    particle.position.y = 100
    particle.velocity.y *= -1

if (particle.position.y > 800):
    particle.position.y = 800
    particle.velocity.y *= -1

this handles the extreme outer-wall collisions.

[lunar venture]

What is the shape of your particles?

If they are round they should hit no more than one or two sides (and of the same box) if they are round shaped

[earnest cloud]

@lunar venture circular particles, this is with only the outer bounds applied. just need to restrict them from ever entering the inner box

[lunar venture]

And what's stopping you from doing something like this for the inner border?

[earnest cloud]

@lunar venture this is the behavior that's throwing me off. this is the code added.

if (p.position.y > 150  and  p.position.y < 750):
    if (p.position.x > 300  and  p.position.x < 900):
        p.position.x = 300
        p.velocity.x *= -1

[lunar venture]

You are setting their position to 300 in both conditions

[earnest cloud]

so ignoring the right side of the region for now and just looking at the left side where the particles are at in the gif, their x-position should always be set back to 300 if they ever exceed that, as long as their y-position is between 150 and 750, i.e. not within the top or bottom gaps

but in the gif, because there's no collision detection for when the particles' y-positions exceed 150 when in the top horizontal section, they jump back to 300 instead of just bouncing off that bottom wall. my problem is having conditions that distinguish those two

[lunar venture]

I think instead of setting it back to 300 it should be updated accordingly with the velocity so they won't stick there

Unless you mean to dampen their velocity once they hit walls

[earnest cloud]

no I do not intend on damping anything. i guess it'd help to point out that the goal of this bounding region is to emulate a wire, and the particles are charged particles. I'm trying to simulate a circuit in the end, so the only "damping" will be the loss in electrical potential, no kinematic business

[lunar venture]

I think you can have two ifs and instead of setting their position attribute to a set position value, update it according to their velocity so it looks like they bounced off in a direction

I want to try doing particle physics myself now lol

[earnest cloud]

it's a lot of fun. interesting to see how they behave. this is the result of just spawning a bunch of positive charges. 30 fps framerate limit on the gif capture makes it look bad but it's really smooth. interesting to see them always orient themselves such that potential energy is at a minimum

[lunar venture]

I've tried doing something in JavaScript and in C#

The C# one has VSync problems I think

Now I'm gonna be doing it in C for the heck of it

Gonna be using WinAPI and GDI32

I think it's okay

[earnest cloud]

I do it in C++ with SFML. though i've had to write basically everything myself since SFML is very limited, just use it for the window and drawing shapes. I'm sure there's much better ways of going about it

[rugged dawn]

hey guys, can someone take a look at this and help me with the problem? i know its some mathematical thing but i really cant seem to figure it out :/ the yellow car is supposed to go to the red dot

i can send a zip file of the code n everything if someone can help

[earnest cloud]

is the car trying to turn around and go back to the first red dot once it reaches the second red dot?

[rugged dawn]

its supposed to turn towards and head to the red dot

the next red dot

[earnest cloud]

right, i assume that's the intended behavior. but does the car distinguish the first red dot from the third red dot once it reaches the second red dot?

[rugged dawn]

it does, i realized that whenever the dot is on the right of the car its fine but when its of the left of the car the issue occurs

wait let me take another recording

should i dm you the zip file?

yea i could look at it

[potent ice]

As in, save files to desktop? (depending on what "folder desk" means)

[torn jackal]

Yes actually my game makes files

And then I d like they go in the folder named desk

[torn jackal]

Thank u very much

[potent ice]

No problem

More about pathlib here: https://docs.python.org/3/library/pathlib.html

[earnest cloud]

i'm beginning to think it's impossible to contain a particle in this region. unless there's a method im straight up overlooking

nvm got it

[normal silo]

If you care about the collision being correct then this method is not correct. It's ok for a video game though because you don't really care about it being correct. For simulation and more advanced games it can matter.

The reason why is because it's moving the particle to the wrong position. The correct thing is to move the particle back to where the collision happened.

The method currently used does this when hitting a right side border:

The correct place to move the particle to would be the intersection between the particle's path and the border.

if (particle.position.x > 950):
    particle.position.x = 950
    particle.velocity.x *= -1
``` The position correcting does not take into account both x and y.

[earnest cloud]

You mean interpolate backwards in time? This is just for simulation of current in a wire, the collisions with the walls aren't important, just that they remain inside the "wire". The energy loss/gain from imprecise collisions would be negligible compared to the energy supplied by a voltage source and the following electric field interactions. I get what you're saying though, it could definitely be improved on

[normal silo]

Yes. But it does not seem to matter for your case.

[pine plinth]

thats why charges in wire propagates only on wire surface

hey guys, i just wanna ask, how can i implement a pause function for a game in pygame?

[latent stone]

You can have a variable initially false, e.g. paused = False. Then you can check for the pause button being pressed, and if it is, set paused = True. Then, before you update the animation you can check if not paused: ...

[rugged dawn]

how can i fill the screen with say white?

keys = pygame.key.get_pressed()
pause = False
if pause == False:
    botcar = BotCar(3,10,TRAIL)
elif keys[pygame.K_p]:
    pause = True
    botcar = BotCar(0,0,TRAIL)
    centertext(WIN,MAINF,"Paused")
    if keys[pygame.K_SPACE]:
        pause = False```
this doesnt work  :( can you help?

the centertext is a function i made to display text in the middle

[latent stone]

pygame.display.get_surface().fill((255, 255, 255))

Or just

screen.fill((255, 255, 255))

if you have a screen variable already defined

[latent stone]

You need to be setting the initial pause value outside the game loop, but checking for pauses inside the game loop

[rugged dawn]

so i make a while loop?

[latent stone]

Your game should already have a while loop if it was working before you tried to add a pause function?

[rugged dawn]

yeah it does

so i set the pause boolean inside?

[latent stone]

Set the pause Boolean to False before the while loop, then inside the while loop check for pauses

Hi, I'm relative new to python and my first posting here.
I'm using pygame and have two sprite groups with around 2000 sprites in one group and around 500 in the second group. Now I need to find the nearest neighbors in the first group for every sprite in the second group. For that I want to use a kd-tree, more specific the cKDTree from scipy.spatial. I have to rebuild the trees every x frames when there are new sprites in group one and/or movement in group two.
How would you call the cKDTree in this case? The cKDTree expects the x, y coords of the sprites as a list of (x, y) values.
Would you copy all (x, y) tupels to a new list to call the cKDTree with it, or is there a faster way to call the cKDTree with the original sprite group? How would that be done?

im having a bit of a problem with pygame
currently this is what I have (attached) and here is the code for a bullet

class PlayerBullet:
    def __init__(self, x, y, mousex, mousey):
        self.x = x
        self.y = y
        self.width = 5
        self.height = 5
        self.speed = 15
        self.angle = math.atan2(y-mousey, x-mousex)
        self.xvel = math.cos(self.angle) * self.speed
        self.yvel = math.sin(self.angle) * self.speed
        self.cooldowncount = 0

    def cooldown(self):
        if self.cooldowncount >= 100:
            self.cooldowncount = 0

        elif self.cooldowncount > 0:
            self.cooldowncount += 1

    def main(self, display):
        self.x -= int(self.xvel)
        self.y -= int(self.yvel)
        pygame.draw.circle(display, (0, 0, 0), (self.x+40, self.y+45), 5)

and here is the bandit script

class bandit:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.image = pygame.image.load("pixil-frame-1.png")
        self.offset_x = random.randrange(-300, 300)
        self.offset_y = random.randrange(-300, 300)
        self.reset_offset = 0

    def main(self, display):
        if self.reset_offset == 0:
            self.offset_x = random.randrange(-300, 300)
            self.offset_y = random.randrange(-300, 300)
            self.reset_offset = random.randrange(120, 150)
        else:
            self.reset_offset -= 1

        if player.x + self.offset_x > self.x - display_scroll[0]:
            self.x += 1
        elif player.x + self.offset_x < self.x - display_scroll[0]:
            self.x -= 1

        if player.y + self.offset_y > self.y - display_scroll[1]:
            self.y += 1
        elif player.y + self.offset_y < self.y - display_scroll[1]:
            self.y -= 1

        display.blit(pygame.transform.scale(self.image, (50, 70)), (self.x-display_scroll[0], self.y-display_scroll[1]))

I don't know how to detect collisions with pygame between a circle and a

so i dont know where to go from there

i would appreciate any help

Hi, im new to python and im trying to make a gambling game basically but its not with real money, currently in this game you can only bet $1 each turn but im trying to so that the user can choose how much money they wanna bet each round

Here is my repl:
https://replit.com/join/smvmjjvxeg-jacknguyen17

[neon tinsel]

Help!!! How do I balance prices in an economy game

Let’s say right now, the best item is 10,000,000. The richest player only have 7,000,000 right now. How do I prevent those items from becoming cheap when players hit 100,000,000?

[boreal grotto]

To a certain degree you can't

I mean, you could scale the prices so they're always high relative to a given player, but if they can accumulate infinite money then there's nothing you can really do to make an item not eventually become cheap

The only things you can really do is limit account balances or impose external costs that ensure they can't make enough money to make something cheap

[neon tinsel]

There’s no equations to set prices? For example, I was thinking of setting some items to a % of the total economy, but that would only hurt the poor players, right?

I wonder if an equation like x/15(e)^x/15

Would work

Or something like an exponential function

Nope, nevermind. Once you hit a point the player couldn't afford it

[short tapir]

.bm

[sharp cedar]

just introduce inflation :p

still practically useless if they’re ultra rich tho

you could try and do something similar to a marginal tax rate system except instead of tax you apply it on prices

[potent ice]

I think you'll always end up having inflation. Especially if there's no cap on what a player can earn over time.

Some games use several currencies to combat this. There's for example a daily cap, but that's more MMOish

Adding tax on trade/auction house and other areas also helps

[neon tinsel]

Yeah, was thinking about this. Although it would be a little tedious to code a tax bracket

[daring jewel]

anybody?

[proud thorn]

is it possible to set a map with ursina? like a vmf file

[prisma solstice]

You could get the bounding box of the sprite and check if any of the corners of the bounds overlap with the circle. Pretty easy to find out if they do bcuz you can just do

if self.x - bullet.x <= (self.bounds.width/2) + bullet.radius: self.freaking die

Oh and check the same thing but with y and bounds height

[daring jewel]

thanks

[daring jewel]

i love the self.freaking die

[prisma solstice]

My throat decided to call that function 2 days ago

I’m super sick rn

[desert vault]

you could basically make a function that runs in background that detects whether a bullet is in the same place (field) that the sprite is

Hey @dawn quiver!

It looks like you tried to attach file type(s) that we do not allow (.mkv). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

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

[steep pilot]

for any of u here who have used pygame before, is there a way for me to make an object have a circular rect ? every object in pygame when u make a rect on it, the rect is a square around the image

yk what i mean, but can i make the rect be a circle around the image ?

trying to make a simulation for gravity :/

[prisma solstice]

bruh

just check if the distance between the center points of the 2 circles is less then the radius of both added together

def dist(x1, y1, x2, y2):
  return (((x2-x1)**2)+((y2-y1)**2))**(0.5)
if dist(self.x, self.y, moon.x, moon.y) <= (self.radius + moon.radius):
  #call collide function
  print("collide")

print("built in syntax highlighting is fun")

hey guys feel free to tell me any ways to improve on this

[vagrant quest]

Hey everyone. I am working on a text adventure game atm and want to to get some feedback from it. Also I am doing a competition for something called YTAC and need people to play my game and click on the link. Don't need to join and hope you like my game!
https://replit.com/@BonkDuck/Dragon-Side?v=1

[potent ice]

You could make a function that presents a riddle and check the response from the user so you can reuse code.

Let's say you had 100 riddles loaded from file

[nova panther]

yea i couldn't figure out that

its was my first time actually using python

[potent ice]

That is fair 🙂

[nova panther]

alot of help from friends was needed

[potent ice]

2 min mockup ```py
RIDDLES = [
("What is the capital of France?", "paris"),
("What is the capital of Germany?", "berlin"),
("What is the capital of Italy?", "rome"),
]
hitpoints = 2

def ask_riddle(question, corect_answer) -> bool:
print(question)
user_answer = input("Your answer: ")

if user_answer.lower() == corect_answer:
    print("Correct!")
    return True

print("Wrong!")
return False

for riddle in RIDDLES:
question, answer = riddle
if(ask_riddle(question, answer)):
hitpoints += 1
else:
hitpoints -= 1

if hitpoints <= 0:
    print("You lost!")
    break

It shows using a function with a return value

You have to answer at least 2 questions right

[nova panther]

bro i shoulda asked for help when the other competition was still going thats what i was trying too do lol

[nova panther]

i think i understand this

[potent ice]

It's an array of tuples with a question and the correct answer

We can "unpack" those values into two separate variables ```py
for riddle in RIDDLES:
question, answer = riddle

There are other ways to do it of course, but at least you need some list of questions/answers

Can also pick a random question ```py
import random
random.choice(RIDDLES)

That assignment is actually pretty nice for learning some programming

I forgot to add a win condition, but that should be easy to fix

Even the example I made above can be improved a lot, but it depends on the use case

[gritty moat]

what would be the best lib for making games, mostly 2d or pixel

[thick knot]

Pygame

[dawn quiver]

Subjective

I'd recommend pygame from prior experience

[dawn quiver]

^

[vagrant saddle]

if you want to run on mobile and web : pygame

[gritty moat]

wbt like macos and windows ?

[vagrant saddle]

it can be the same code if that's you want to know

[gritty moat]

but can i still make games with pygame for windows and macos ?

[vagrant saddle]

sure

[vagrant saddle]

see https://pmp-p.itch.io/stuntcat , it can work on web, ios, android, windows macos linux bsd and probably others with the same code archive ( nb it's pygame 2 which uses SDL 2)

[steep pilot]

in pygame, how can i make an object be attracted to a point ?

i can move rectangles 50 pixels on the x axis or 50 pixels on the y axis but can i make a rectangle move to a certain point ?

for example, making a circle move towards the center of another circle

[glacial leaf]

i need some help, how do i make it so that this error gets ignored?

i remember fixing it by typing "#" and some word after it

[proper peak]

The easiest way would be to use some vector math. Subtract the body's position from the target's position - that's the vector from the body to the target. Rescale that vector to a length equal to how much you want to move per tick. Move the body by that vector.

[steep pilot]

okay, ill do a bit of research into vectors

thanks for the suggestions ill look into that as well

[daring jewel]

whats bounds

#☕help-coffee

[tranquil girder]

use lerp
pygame.math.Vector2.lerp

[visual terrace]

does anyone know if pygame has a button.just_pressed() function or something like that

?

[steep pilot]

why exactly lerp ?

[tranquil girder]

lerp is short for linear interpolation and is meant for exactly this, interpolating from a to b

[twilit echo]

Is there any lib for making card games?

It should have stuff like images also

[vagrant quest]

Hey everyone. I am working on a text adventure game atm and want to get some feedback from it. Also, I am doing a competition for something called YTAC and need people to play my game and click on the link. Don't need to join and hope you like my game! https://replit.com/@BonkDuck/Dragon-Side?v=1

The source code can be found with the Replit.

[potent ice]

It works pretty nicely. One obvious improvement here should be to put all the player attributes into an object or class so you don't have to rely on global. Whenever you hare forced to use global it's a sign that there is a better way.

Maybe also the same for an enemy that has a set of properties 🙂

[thick knot]

It’s very interesting

[potent ice]

I also think if you defined long strings like this the source could be more readable ```py
lookCave = (
"As you look around you start to feel a sense of danger. The cave is creepy "
"and illuminated by a couple of torches and natural light. You can also see a sleeping bear "
" and the [cave exit]. Maybe you should [attack the bear]? "
)

This will turn into a single string and will not break the indentation making the game code much cleaner to read since you can follow the indentation to quickly see the blocks / structure.

In theory it would also possible to make the game more data driven to avoid making custom functions for each step.

That's at least two simple things + one larger thing that could be done to improve it 😄

To be a knit picker: Python style is "snake case" so we use lower case function and variable names like def scroll_text(text) and look_burning_tower. Classes can title case like Player.

You have still managed to use functions to greatly reduce the amount of code, so that's great work. This is pretty complex code if you are a beginner.

@vagrant quest I think that's all I'm going to say right now, but be free to ask if needed.

[vagrant quest]

Thanks so much for the advice. Made in two days for competition and hadn't really used classes before so
definitely want to try some of that.

[dawn quiver]

hey, i am currently learning the fundamentals of 3d rendering and currently learning how to multiply matrixes. short question, is it correct that you need to following ```
A B
[ 1 2 ] [ 2 3 ]
[ 4 3 ] [ 2 3 ]

step 1: 12, 22
step 2: 43, 33

REALLY new to this please don't judge, i never had this in math or in school general

what do i do next? i only have the first column of the result, 6 and 14

nvm i am dumb

[dawn quiver]

okay, other question: how do you multiply multiple matrixes? i mean more then 2

[potent ice]

You just keep multiplying them. Just remember that matrix operations are not commutative, meaning A x B will not give the same result as B x A. Multiplication order matters.

There are plenty of resources on how do do the actual multiplication math. Just make sure you don't confuse rows and columns

Matrixes come in two flavors. Stick to one of them: https://en.wikipedia.org/wiki/Row-_and_column-major_order

[dawn quiver]

Hello.

We maintain a pretty good example for that.

In 2.1.3+ you can use pygame.Vector2.move_towards

But this example assumes you use a lower version (since only the dev versions of 2.1.3 are out so far)

We have two related examples actually.

Panda is soon rolling out support for Vulkan.

[potent ice]

I was talking about going low level in that instance, and yes I know panda is going vulkan 🙂

[potent ice]

You need to share a lot more information about this app and how it's related to game development. Preferably also link a public repository with code.

[ionic plume]

I'm trying to draw a WWE ring but I'm having SUCH a hard time with the X and Y coordinates input and output.

Pygame, basic shapes.

[potent ice]

What have you tried so far? I also think most people don't know what a "WWE ring" is.

[ionic plume]

.... It's a professional wrestling ring.

@potent ice I'm suffering with guessing coordinates!

[potent ice]

0, 0 is in the upper left corner if that helps

[ionic plume]

I get that.

[potent ice]

I think pen and paper can solve that problem.

[ionic plume]

I don't have graphing paper. 😔

How can loose-leaf help?

[potent ice]

There are techniques for drawing things in perspective by using perspective lines. You could look that up. The idea is to get a few rough control points. That can be done without graphing paper

[ionic plume]

I'm learning!!!! 😭😭😭😭😭😭😭💕💔💔😭

I never learn!

[potent ice]

If you have a ruler you can also get the main points from an existing image

or you can use pixel location in an image with mspaint

That might be much easier

[ionic plume]

I wonder why I haven't learned about this!

[potent ice]

windows paint use same coordinates as pygame, so that should be super easy 😄

@ionic plume

So if you scale/crop the image to your window size, you are good to go

[ionic plume]

AHHHHH WHY HAVEN'T I LEARNED THIS FROM MY PYTHON BOOKS!! 😭😭😭💔

[potent ice]

It's all about being creative finding good solutions. Open your mind 😄

[ionic plume]

I thought I just had to... Read books.

[potent ice]

It's probably a bit too specific to be covered in a book 😄

[ionic plume]

You're amazing! You're my hero!!
Can I DM you if I need more help? 🥺😭

[potent ice]

It's all part of general creativity when solving problems. It's something you can get better at over time.

I don't do DMs, keep questions here

[ionic plume]

Okay with me.
But my goodness you, really helped me leap a giant foot forward!
Thank you again!
I would've continued to suffer so much with no avail.
And you're right, MS Paint really DOES measure your pixels, I would've never thought of MSPain in a million years.

I have one more problem. I need help with.
It has to do with moving a square on my screen

[steep pilot]

is there anything representing pygame.Vector2.move_towards in version below 2.1.3 ?

[dawn quiver]

No

[steep pilot]

mm okay

thanks a lot for the examples btw

they are already helping

respect

any clues to when 2.1.3 will release btw ?

[dawn quiver]

This one basically just implements move_towards specifically for this
https://github.com/Matiiss/pygame_examples/blob/main/pgex/examples/move_towards_mouse/vector2.py#L12
You could use that instead

[frank field]

pgex/examples/move_towards_mouse/vector2.py line 12

class Vector2:```

[dawn quiver]

Soon, they are trying to get it out as fast as possible

[steep pilot]

will look into it rn

[steep pilot]

hope it comes out soon

[dawn quiver]

You can still use its features through dev versions

pip install pygame==2.1.3.dev4

[steep pilot]

oh

i was trying to see if there are any updates for it but there werent

but this works ?

huh

[dawn quiver]

Yeah

But this is a dev version for a reason

[steep pilot]

perfect

[steep pilot]

any downsides or ?

just bugs

i assume

[dawn quiver]

Stability maybe, but the contributors think otherwise

[steep pilot]

mm okay

[dawn quiver]

Some things could be subject to change in the actual 2.1.3 for sure

[steep pilot]

alright

u can still use python sure, but C# comes with lots of ways to make games, unity game engine for example is one

[native trail]

I challenged my self to make it in 3 months only

[steep pilot]

a game engine ?

[native trail]

yes

hard

very hard

[plain junco]

3 months

[steep pilot]

thats a nice challenge , i respect that but 3 months only

for a WHOLE game engine

[plain junco]

isn't realistic

[native trail]

yes

[steep pilot]

yes its not enough u need way more time

[native trail]

I named it Gold engine

[plain junco]

thousands of llines of code

[native trail]

it's gonna be buggy and 3d

[plain junco]

lines

[native trail]

currently the graphics.py

has a lot of lines

don't worry I'm using numba for performance

cuz python is little slow

[plain junco]

Ok, good luck mate

[native trail]

thx @plain junco

[steep pilot]

u need to learn insanely more to make a whole game engine, get a solid grip of classes , solid grip of the whole logic of how programming works , make a few side projects here and there, interesting things that are challenging like for example visualizing a sorting algorithm or simulating gravity, or making something like a small game with interesting and unique stuff in it, u cant just go from nothing to a game engine

[native trail]

gold engine currently

don't have even collision

but

it can draw

.fbx and .obj and .egg

3d models

if u want 2d

then go with other version

yeah

big dreams, but small PP

[steep pilot]

nah

[native trail]

look

[steep pilot]

big dreams and big pp i respect u for trying man, almost no one would try such things

[native trail]

I really love c++

[steep pilot]

C++ is good yeah

[native trail]

but python was the challenge

[steep pilot]

old ass language but really fundemental

u should have done C# or C++

[native trail]

we choose c++ just for performance and good graphics Libs

I tryed unity

I liked Godot

[steep pilot]

godot is good

[native trail]

GDScript

[steep pilot]

for 2d games a lot

ye it uses GDScript

[native trail]

simliar to python

[steep pilot]

yep

[native trail]

gimme a second

[steep pilot]

really similar to python actually

why not try using godot ? to get a grip of how making games works

[native trail]

send my a friend request

cuz I made a lot of games

[steep pilot]

u dont copy code from github and shite like that right

[scenic shoal]

Guys can you make a good game using pygame precisely a top down game .

This feels very much like an advertisement which is not what this channel, nor our server is for.

[potent ice]

I don't see why not

[frank mulch]

hi i made a game with pygame and turned it into an exe using pyinstaller, the code had the sql database's information (host, password, user) so is it safe?

[potent ice]

If that's a public facing database.. then definitely not

[frank mulch]

how can i secure it?

[potent ice]

Why do you need the database credentials in the game client in the first place?

[frank mulch]

.__. to store the highscores and shit?

[potent ice]

You should instead make server/service the client can use to store that stuff.

[glossy elm]

Thinking of a little project - and whilst I like Python more than TS, last game things have been in Pixi.js. So, little out of the game, Python Gamedev wise. Question is - is Pygame still the 'gold standard' in game dev libraries in Python? I presume nothing is being transpiled to asm.js and supports a HTML5 canvas yet?

[dawn quiver]

You can run pygame applications on the web now.

Made entirely possible by @vagrant saddle

music isn't played in the same no of loops as mentioned in the code
i used mixer of pygame module
what might be the problem ?
plz help
here's my code: ( if i change play(0) to play(1), the music will still be played only one time)

import datetime
from pygame import mixer

tme = datetime.datetime.now()
x = int(tme.strftime("%H"))

if x <24:
    mixer.init() 
    mixer.music.load("Drink.mp3")
    mixer.music.set_volume(0.7)
    mixer.music.play(0)
    v = input("Enter 'DONE' when you finish drinking water:\n")
    if v == "DONE":

[dull hound]

Do you watch someone's python course on YouTube? Ig

[cunning shadow]

So i've been wondering, how should I manage a game state?

Like say I want to have a cutscene play, then return to the main loop, or the player opens an inventory or gui screen, then returning to the gameplay itself...

How do I keep track of the fact that the person would have passed the cutscene etc, or completed an action that would then cause the rest of the game to continue like normal

This is one thing that has had me stuck for the longest while now.

Would I just have to like, make a bunch of variables for all the different options etc, then have them
if then?

Or maybe an external file which will keep track of the state of the game?
I'm not sure

For example, say I'm using Arcade, and making use of their Views, when I switch back to the gameplay View, then the class would get reinitialized... so I'm really stuck here 😅

And If it is better to use an external file or something, what exactly should it contain and how should I read from it?

Thank you in advance!

[frank field]

Hey @lyric pawn!

It looks like you tried to attach file type(s) that we do not allow (.avi). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

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

new biomes and materials 🙂

will be adding a gui this afternoon, and you can currently choose the material you build with as well (water, snow, rock, grass and sand)

[potent ice]

I simple improvement could be to do chunk generation with multiprocessing. Just request chunks on a queue and get raw data back you can use to build the chunk. (non blocking writes and reads to queue)

[lyric pawn]

Thanks for the feedback 🙂 I do have a queue for chunks generation, I do not really know how to do it and if it is possible on python to do real multiprocessing, I have only tried threading and so far it's just slowing down the whole thing, especially framerate.

I heard it was pretty much impossible to achieve real multiprocessing on python, but I'd like to be wrong 😄

[potent ice]

Yeah you have to use multiprocessing to use all cores. Threading in python will slow down main process 🙂

[lyric pawn]

Yeah that's exactly what I want to achieve but I haven't looked deep at it for now

[potent ice]

Multiprocessing works fine even for realtime things in my experience.

You just need to make sure you read and write to the queue non-blocking

[lyric pawn]

https://stackoverflow.com/questions/44983304/how-to-achive-true-parallelism-with-thread-in-python

Yeah I was reading this and It seems like threading in python is a bit different than multiprocessing

Will try with multiprocessing for sure this week or even today, thanks a lot !

[potent ice]

Threading is great if you are doing IO or light work. Anything more than that will crush the main thread

[lyric pawn]

Yeah I see if you need a bot that calls multiple urls or so it's okay but does not really accelerate anything in the end

[potent ice]

Just make sure the data you send in the queue is simple/generic. It's pickled and transferred between the processes. Not all objects can be pickled. You might have to quickly build the vertex data in the main thread, but this still means the subprocess will do the expensive work. I found it worked well to only read and create one chunk per frame to throttle things a bit.

Can also go fancy with "shared memory" later, but I don't think that is necessary for chunks

[lyric pawn]

Thanks for the advice 😉 I was thinking of that too, I don't think I call call any engine function from another process, will do some tests this afternoon

[potent ice]

It should work pretty well I think. If things get tights in the main thread you can use a generator function with timeout or fixed amount of work so you can continue in the next frame. It's worth adding to keep smoothness.

[minor pendant]

Good evening! I have this problem, may I ask what causes it?

[lunar venture]

Use // instead of /

range accepts int values only

[minor pendant]

Wow! That solved my problem. Thank you!

This channel is about game development. Random images from games are kind of off topic unless it's in the right context 🙂

[lyric pawn]

I will be pushing the code in few minutes to github, I have done multiprocessing on most of the tasks related to chunk loading and I have done many more optimization regarding wether the player is moving or not

It is now way more enjoyable to move and look at the terrain being generated, everything seems smooth, still need to fix a bug where my chunks don't seem to get sorted by distance (doesn't happen often) even if i force it to be

Nice 👍

iAM ON windows 7. ii am using pygame to animate this sprite when it moves it leaves a trace. HELP

also i have to click then take of my finger then re click to move i cant do a prolonged click

Hi!

[orchid fox]

yea thats because theres no surface behind it

you need to put somethig like a pictue or something behind it

and behind it means behind it in the code

[lyric pawn]

started adding a gui to my minecraft prototype today, also made using Harfang

[lyric pawn]

I am using Harfang 3D as an engine and it's Python package so the language is Python 🙂

just updated the repository with the gui and the most recent version

you can build 5 materials as of now, and I have also added 2 levels to the terrain generation (stone and snow)

[versed cedar]

Hello, I have a question. Why does this happen? When I click the SETTINGS text, instead of disappearing, the text comes back. I figured it out that is because the python haves the hold Mouse function and not click. How can I change it to a click function? In advance, thank you very much for your help.
Here is the code:

import pygame as pg
import pygame
import self
import self as self

import mouse
from pygame import surface

pygame.init()
screen = pygame.display.set_mode((400, 400))

X = 50
Y = 200
running = False
silver = [190,194,203]
black = [0,0,0]
self.clicked = False
left, middle, right = pygame.mouse.get_pressed()
click = pygame.mouse.get_pressed()
pygame.MOUSEBUTTONUP = True
def Title():
    pygame.display.flip()
   
    screen.fill(silver)
 
    pygame.display.set_caption('AVATAR PVP')
  
    pygame.display.update 
 
def AVATARPVP():
    font_obj = pygame.font.Font(None,25)
    text_obj = font_obj.render('Avatar PVP', False, black)
    screen.blit(text_obj, (50, 100))
def START():
    # START
    font_obj0 = pygame.font.Font(None,16)
    text_obj0 = font_obj0.render('START', False, black)
    screen.blit(text_obj0, (50, 210))
def SETTINGS():
    
    font_obj1 = pygame.font.Font(None,16)
    text_obj1 = font_obj1.render('SETTINGS', False, black)
    screen.blit(text_obj1, (50, 260))
def EXIT():

    font_obj2 = pygame.font.Font(None,16)
    text_obj2 = font_obj2.render('EXIT', False, black)
    screen.blit(text_obj2, (50, 310))
    # 50 i 90 310 i 325

def MOUSECLICK():
    if event.type == pygame.MOUSEBUTTONDOWN: 
       
       posx, posy = pygame.mouse.get_pos()
       print(posx, posy)
       if((posx >= 50 and posx <= 90) and (posy >= 310 and posy <= 325)):
           exit()
       if((posx >= 50 and posx <= 130) and (posy >= 260 and posy <= 270)) or event.type == pygame.MOUSEBUTTONUP:
   
           screen.fill(silver)
while not running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = True
    Title()
    AVATARPVP()
    START()
    SETTINGS()
    EXIT()
    MOUSECLICK()

[dawn quiver]

nice

[dawn quiver]

yeah i added a background and it worked thanks

u can also make a update function and call are your functions in there. and only call the update in the main loop. looks cleaner

[frank field]

Hey @hearty quartz!

It looks like you tried to attach file type(s) that we do not allow (.zip). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

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

[hearty quartz]

https://github.com/nate-4000/TSPUDTTY

I made this game, any code cleanup or efficiency comments?

[potent ice]

A first step would be to put the contents of the zip into the repository instead of the zip file itself

[hearty quartz]

oh

im dumb

hold up

[proper peak]

a good idea would be to not add files via upload, but making a local repo looking like you want, then git pushing it to github

[hearty quartz]

git push doesnt work, just tells me that the git file does not exist

[proper peak]

did you create a repo in the folder with git init?

[hearty quartz]

yes

i even git remote'd it

oop wait...

i just ryed agian

i'm a dumb***

i forgot to make the github repo

done

[hearty quartz]

hello?

you guys dissapeared

[proper peak]

seems to me like you're usually not handling the case if the input is wrong

[hearty quartz]

yeah, i dont know how to do it without a try: ... except: ... block

[proper peak]

you could make a helper function

def inp_num(prompt:str, max:int) -> int:
    while True:
        try:
            res = int(input(prompt))
        except ValueError:
            print("Please enter an integer")
        if not (1<=res<=max):
            print(f"Please enter an integer from 1 to {max}")
        else:
            return res

e.g. that.

[potent ice]

Put __pycache__ in a .gitignore file

[hearty quartz]

kay, so i just do something like

stdin = inp_num("> ", 3)
# instead of
stdin = int(input("> "))

[hearty quartz]

how

[potent ice]

1. Delete __pycache__, commit and push
2. make a file called .gitignore with the following contents

__pycache__

add, commit and push.

__pycache__ contains compiled bytecode. It's not necessary to have in the repo just making a lot of noise in the change history

When you make a repository you can chose from several templates. The "Python" template will include a common sense .gitignore

It will just make sure you don't include unnecessary local files to the repo

[hearty quartz]

done

alr i have to go

bye

Hey there. I am trying to make a type of Wordle game. This is my code:

import random
import time

f = open("words.txt", "r")
random_words = f.readlines()

word = random.choice(random_words)
forbiden = ["\n"]
positon = 0

for char in word:
    if char not in forbiden:
        letters = []
        letters2 = []
        letters.append(f"{char}")
        letters2.append(f"{char}{positon}")
        positon = positon + 1
        print(letters)
while True:
    inp=input("Your guess (5 letters): ")
    pos2 = 0
    for char in inp:
        print(char)
        char2 = f"{char}{pos2}"
        pos2 = pos2 + 1
        print(pos2)
        if char2 in letters2:
            print("Correct letter and position: " + char)
        elif char in letters:
            print("Correct letter in wrong position: " + char)
        else:
            print("Wrong letter: " + char)
        time.sleep(2)

Output:

['m']
['o']
['g']
['u']
['l']
Your guess (5 letters): mogul
m
1
Wrong letter: m
o
2
Wrong letter: o
g
3
Wrong letter: g
u
4
Wrong letter: u
l
5
Correct letter and position: l

Why does it only say that the last letter is correct only?

[vagrant saddle]

in the first for loop you are recreating letters2 = [] each pass, it will only contain last letter

[oak orchid]

Shouldnt it do it for all of the characters?

[tranquil girder]

you should create the empty list before the loops, not make it a new empty one every iteration

[oak orchid]

oh. Now i get it. Your right. Thanks for the help.

There is an ocean of resources for pygame if you search around. What you need might depend on your experience level. There are free books (http://programarcadegames.com is one of them), the official pygame docs (https://www.pygame.org) and probably hundreds of youtube videos. There is also a pygame discord server.

you can also use pygame-zero to simplify the initial tasks, and that serie was nice https://github.com/TechnoVisual/Pygame-Zero ( it also work out of the box on web )

That's a whole lot to ask for. It's much easier to get a response from smaller question. For example: A very specific problem you are struggling with related to your game.

[stuck mountain]

ok

[warm vector]

Hello! Do you guys have any advice on how I should store world data? I am currently storing the world using multiple txt files with an item id table, but I would want a more efficient one.

[sharp cedar]

Depends. do you want it local or online? how big is it gonna get? how often do you access this data? do you write to it more often or read? do you need frequent access to it? etc a lot of the times, a text file might just work

[potent ice]

Also depends what you mean by "a more efficient one". That's the problem with the current solution?

[dawn quiver]

im making a hobo life game

i made a typewrite ```py
import time
import colorama
color = Fore.YELLOW

msg = """hello welcome to hobo life"""

def typewrite(msg, wait=0.20):
char_amount = 0
for char in msg:
char_amount += 1
print(color + char, end="", flush=True)
if char_amount == len(msg):
print("", end="\n")
time.sleep(wait)```

[dawn quiver]

better one it was sending a weird symbol at the beginnig of type write so i have its end " " at beginning to get rid of that error ```py
import time
import sys
from colorama import *
import os

first_typewrite = False

def typewrite(msg, wait=0.2):
os.system("cls")
global first_typewrite
color = Fore.YELLOW
if not first_typewrite:
first_typewrite = True
typewrite(' ')
os.system("cls")

char_amount = 0
for char in msg:
    char_amount += 1
    print(color + char, end="", flush=True)
    if char_amount == len(msg):
        print("", end="\n")
    time.sleep(wait)```

[dawn quiver]

you can change color to whatever you want

this has something to do with game development bc ppl can use this for text based games and im using it in my game

[burnt plaza]

Hello I need help with a simpler game

Can anyone help me please

[tranquil girder]

Help with what?

[thick wasp]

im making a small game in pygame and need help with collisions detection, i wanted to know what the best option would be to make it work

my code has a player class, and idk how to make another object which he can jump on

[warm vector]

sorry for the late reply, but I would like one which stores multiple layers of tiles, instead of having a text file for each layer. My friend is telling me that he is using tiled XML, but I am not sure if it would suit my needs

[normal silo]

Tiled XML is not more efficient in any way. It's used because it's what the Tiled editor outputs. So it depends if you want to be able to use that editor or not.

[warm vector]

Okay, but do you know of a better way of storing tiles? Like I said in my previous message, I would like one which can store multiple layers of tiles instead of one file per layer.

[normal silo]

You can create whatever file format you want.

Also is storing a layer per file actually a problem?

Are you ok with it?

[warm vector]

Not currently, but it might be a problem in the future. It's fine right now, though.

[normal silo]

Solve it when it actually becomes a problem. Until then, write your code in a way such that that part can be swapped out without affecting anything else.

"abstracted away"

[warm vector]

Okay, thanks for the help!

[normal silo]

If by more efficient you meant the speed with which you can create maps. Then Tiled can certainly help with that, although I prefer the more simple "dumb" method of using an image for the map where each color means some tile.

Something that works nicely in 2D games.

(With this method you can create maps in photoshop or whatever)

[warm vector]

I could try that, but creating a text file of the map is kind of similar.

[normal silo]

Yeah, just do whatever you prefer.

[warm vector]

Okay

[normal silo]

(You can even support multiple types later if coded correct (text, images, XML))

(So you don't need to throw away work)

(Or write a converter tool)

[warm vector]

Got that, but I have an unrelated question. How do I get all the colours used in an image? get_palette() doesn't seem to work. I am using pygame as the library of choice.

I am getting the error pygame.error: Surface has no palette to get, though I'm not sure how I can fix that.

Also, please ping me if you have the answer.

Hey @zenith orchid!

It looks like you tried to attach a Python file - please use a code-pasting service such as https://paste.pythondiscord.com

Hey @zenith orchid!

You either uploaded a .txt file or entered a message that was too long. Please use our paste bin instead.

[thick wasp]

how do u make 2 classes interact with each other?

[cerulean nimbus]

can you explain more in detail of what you mean

[thick wasp]

like i want to have a player class and a block class, i wanna use these 2 classes to be able to have them collide with each other

how would i approach this situation

[lost needle]

One way to do this is keep track of what you’re waiting to do, and what time to do it, in a list or similar. Then keep a timer running and when it becomes time “return” to the task by calling a function

WIP : Socket Server - Client made in Python using Harfang library.

Someone know the names of them?

[frank field]

Rules

[potent ice]

You might just want to delete what question and move in. It's 100% clear it breaks the server rules.

[short rivet]

But here is game development everyone moving me from place to place can someone just direct me like

[sinful lodge]

you can use rect collisions, pygame has some methods for that (search up pygame AABB) so the rects can act like the different hitboxes

[forest bay]

hey can someone help me?
im trying to change values in an object but when i call the function that changes something it doesnt change

#EX.
def register_Clone(self,spritelist):
            self.clonecount = self.clonecount + 1
            clone = Sprite(self.name,self.pos[0],self.pos[1],self.costumelist,self.spritefunc,(self.clonecount,self.clonecount,self.currentcostume))
            spritelist.append(clone.get_object())
            return spritelist
``` when it runs the first peice of code it changes but only inside the function
so when it gets to running the sprite's function it says that the clone count is 0 but when it runs the clone's version it says 1

i can also provide the full spritehook.py

You can't ask for help to memory hack GTA5 anywhere on this server. It's that simple.

[unkempt gazelle]

Anyone know the performance difference between pygame, panda3d and ursina? Both 2d and 3d games. Which would be the best for 3d performance wise, and which would be the best for 2d performance wise?

I havnt stress tested ursina and panda3d, but with pygame i can render 3500 2d circles at once with only using basic for loops and lists while staying above 60fps. And my pc is a potato.

Not too familiar with ursina or panda3d, so cant stress test them fairly.

[normal silo]

Generally, Panda3D will be the fastest. Potentially by a large margin depending on what you are doing.

Ursina, being a Python extension of Panda3D, can match Panda3D at best.

Pygame is not really meant for 3D.

[unkempt gazelle]

Is panda3d faster than pygame with 2d aswell?

[normal silo]

Yes. Especially if you are using C++ and not Python. In both cases your Python game logic may be the limiting factor. If Python is not the limiting factor then Panda3D will often be faster.

[unkempt gazelle]

Ok thank you. Ill have to learn panda3d.

[normal silo]

Newer versions of Pygame are totally fine for 2D unless you are really going wild with it.

[dawn quiver]

if the position is the same as before you could have it not print it in that console

[unkempt gazelle]

I will be going wild lol

[normal silo]

Millions of objects?

[unkempt gazelle]

Possibly

Physics simulation

[normal silo]

I would just do the more effort route then and go with Panda3D.

Def. not as simple to learn though.

[unkempt gazelle]

Learning hasnt stopped me with anything yet lol

Thank you for helping me out with this

[normal silo]

Panda3D provides 3 different physics options, I recommend Bullet3D.

[unkempt gazelle]

The simulation will be on an atomic scale, so particles will attract and repel each other

[normal silo]

Ok, then you can do that yourself.

[unkempt gazelle]

Ye

[normal silo]

That is best done in either C++ (Panda3D provides both C++ and Python APIs that match) or with compute shaders (which Panda3D also provides an API for).

Or maybe you prefer OpenCL, which you can do from Python with Pyopencl.

[unkempt gazelle]

Is pyopencl faster than pygame?

[normal silo]

If you are unfamiliar with GPU computing then I would not worry about it yet.

[unkempt gazelle]

Ok

[normal silo]

If you only need a couple of particles Python is fine.

If you want a lot, then switch to C/C++ or Cython.

However, the largest initial gains will come from algorithm complexity improvements, which you can still test while in Python before switching.

Rendering is all handled by Panda3D so it's not like you need a manual draw loop.

[short rivet]

Bruh im trying to learn making bare scripts look them up at github takes memory overwrite this is the most basic and i cant do it

[short rivet]

The point is not hacking but as i know pymem is a library that is ok to use to overwrite memory

[lyric pawn]

It's not printed anymore in the current version 🙂

[normal silo]

An edge is defined by two end points. So you already have three edges right there. For three edges you need 6 points, but each edge in a triangle shares its two end points with two other edges of the triangle, so having it listed as 6 points would have 3 duplicates. So three points is all you need.

If by find the edges you mean the edge lengths, you can apply the distance formula for 3D:

What did I just walk into

[potent ice]

You walked into some basic math used in games? 😄

Hey @lament gyro!

It looks like you tried to attach file type(s) that we do not allow (.zip). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

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

[echo moat]

how does 3d work on the screen and can python be used for 3d games without using 3d engines

[lament gyro]

Hey i am trying to make a placing and breaking system for my game, i have already managed to make an efficient breaking system.https://www.mediafire.com/file/hawhfy2a86kzacy/game.zip/file

[echo moat]

like making your own, ik it would be very difficult

[potent ice]

You can definitely do 3D without any fancy engine, but that requires learning quite a bit. Most people use 3D engines unless they have special cases.

[vagrant saddle]

you can study the code of TinyGL (https://bellard.org/TinyGL/) or the very complete OSMesa those are two libraries you could use in python to do complex 3D without 3d hardware engine. but it will be very slow

3d for mobile is a bit different see https://github.com/lunixbochs/tinygles instead

[exotic fern]

curious

what does the "normal projection" of a point mean

i have a triangle defined by (x1,y1,z1), (x2,y2,z2) and (x3,y3,z3) and i have a point (xp, yp, zp)
if i have to find whether the normal projection of the point lies within the triangle
then i have to find the projection of the point (xp, yp, zp) in the plane of the triangle, and then use that point to check - right ?

hi i created a game and posted it to my github

but how do i put the python files and folders into an index.html so that I can run it in github pages

[vagrant saddle]

hi, if it's a pygame / canvas2D/3D or vt420 game use https://pypi.org/project/pygbag/ more info here https://pygame-web.github.io , if it's text only with input() then maybe pyscript

to automate publication use github actions copying that yaml file https://github.com/pmp-p/pygame-breakout-wasm/blob/main/.github/workflows/pygbag.yml in your project ( as .github/workflows/pygbag.yml ), then run CI action (wait 1 minute or 2 ) then select [gh-pages] in combo list for web root in [projects settings]/[pages]

Hello guys I have a very solid knowledge about python and I want to start making games with it I want some tutorials about it (all of them tbh) and I have a previous experience on making games with godot but this time I want to make a game with pygame ,I will be very glad if you sent me some good tutorials .
Thanx for your time .

[viscid maple]

I don't know many pygame tutorials, since I mostly used books and personal projects to learn, but I see the work of Al Sweigart being complimented a lot. Here's an useful link of his materials regarding pygame: https://inventwithpython.com/pygame/

If you want to take a look at more advanced stuff, DaFluffyPotato is probably one of the most advanced pygame users at the moment, here's his youtube channel https://www.youtube.com/c/DaFluffyPotato with a lot of video tutorials

Remember I never followed any of these tutorials, so take my advice with a grain of salt, although, the guys behind those seem to know what they're doing, and Sweigart is an acclaimed Python author.

If you're interested, I also published a multi-purpose node editor made with pygame, totally free of charge and dedicated to the public domain. Here's the github link: https://github.com/KennedyRichard/nodezator. You can install it with pip install nodezator

Here's a video presenting it https://www.youtube.com/watch?v=GlQJvuU7Z_8

It's asking you what "ball" is. You never say what it is

there's no variable named "ball" in your code

[sterile iris]

i still didnt understand

;-;

[tranquil girder]

to make a variable called ball, you'd have to do ball = something right?

where do you do that?

[muted iron]

in the code ?

You should use numpy matrix and then you can use a module called msgpack-numpy to encode and decode

also use UDP thanks

🌟 👉 hi guys, if you are into generative AI/generative art, you must try this Python library https://github.com/jina-ai/discoart super easy to use as long as you know a little bit Python and smoothly run with free GPU on Google colab! for example, one can use it to generate pixel item like this

[viscid maple]

Since its release a few weeks ago Nodezator is dedicated to the public domain, which means it is everyone's now. Feel free to use the source as you see fit. I actually made Nodezator so that it could be integrated into the workflow of any software using Python, specially because the node layouts used on it can be exported as plain Python code. It can also turn any callable into a node automatically, which means you can turn any callable from any project on pypi (hundreds of thousands of projects). If you want to know more, check the manual on https://manual.nodezator.com and for any questions/concerns/constructive criticism/feature requests or simply to follow its development check the discussions page at https://github.com/KennedyRichard/nodezator/discussions

[sharp cedar]

what's the best way to represent tetris shapes in python? a list should be good but would it just be a 4 by 4 where some cells are going to be 1 depending on the shape?

[broken citrus]

consider using numpy and msgpack-numpy it will speed up everything

[lyric pawn]

Thanks 🙂 I will try it out tomorrow, and I have made a udp server / client today, started to add some linear interpolation and will add more features like lag compensation, prediction when it will be good enough for me

[lyric pawn]

Prediction implemented on server-side for now:
Blue : The last position received by the client from the server
Green : Linearly interpolated client's position
Red : Prediction of the actuel client's position (not yet received by the server)
The main goal was to train myself to do interpolation with network data correctly and it was cool to have all the infos at the same time (so I can implement them in the client side next 🙂 )

yall python hates me<3

i dont understand this shitn anymore

ok nvm im just dumb i got smth wrong with the equatiom

[proven gorge]

is pygame used for any serious games or is it just a toy? please ping me when responding.

[vagrant saddle]

"serious game" means usually educationnal subgenre, but i guess you meant "nice playable games" and then the answer is yes. Though usually a prototype could be made with pygame and recoded later in a compiled form before distribution without anyone knowing

[proven gorge]

I ment nice playable games

meant*

[vagrant saddle]

have a look to some very nice games here https://dafluffypotato.itch.io , can even run them on web out the box : see one here https://pmp-p.github.io/pygame-wasm/pygame.html?com.dafluffypotato.aeroblaster

right now I am learning python. I want to make a multiplayer web game in the future. What language is best for a high performance web game?

[vagrant saddle]

anything that compiles to webassembly

though above web demo is running cpython wasm + pygame so it is still interpreted by python

and it sill runs very well

sometimes cython is all you need to get more performance

[proven gorge]

what is cython

and how hard is it if you have a python game to turn it into a cython game?

[vagrant saddle]

i don't know i never had to use it myself

usually python is fast enough (for me)

[proven gorge]

what if you have to be checking collisions between 50 sprites?

[vagrant saddle]

i'd use pymunk for that

[proven gorge]

this is my game so far

now I am going to try to get the player to move based on their width and time

can someone help me with connecting the events from pygame to the event_queue

[vagrant saddle]

why would you want to handle pygame events asynchronously ? the one and only await should be after the pygame.display.update()

[rustic valve]

ight

can you inherit from pygame

or is that weird

[vagrant saddle]

anyway if you want to async discard some jobs because you are too late you'd need a priority queue and component event handler / drawing separated ( like in an ECS )

probably there are some capable libraries for that

and no need to asyncio to do that it just adds overhead

[rustic valve]

alright

so no asyncio cause

its very hard to do

[vagrant saddle]

a typical asyncio pygame loop should look like that https://pygame-web.github.io/wiki/python-wasm/

no need to pollute all code with async

[rustic valve]

where was game state defined

[vagrant saddle]

game_state is a function pointer

in simple games it should point to current menu or game event handling + drawing

in complex games it should point to a scheduler handling a list of prioritized jobs

[rustic valve]

is a match statement

good for events

[vagrant saddle]

pygame events are numerical so something like a computed goto / dispatch table (with a dict ) is maybe faster than patma

[rustic valve]

ah

ic

[rustic valve]

im trying to

use a

api

in the game

it works, but its slow

Hey @rustic valve!

You either uploaded a .txt file or entered a message that was too long. Please use our paste bin instead.

[vagrant saddle]

you are blocking with I/O at 59

await self.get_word() should be a task, and should send a pygame event

[rustic valve]

so make it a pygame event, on the event, create_task

how do i make an event again

🗿

[vagrant saddle]

custom_event = pygame.event.Event( event_number)

here's a example of a green thread (coroutine ) sending events https://github.com/pygame-web/python-wasm-plus/blob/main/support/__EMSCRIPTEN__.overlay/pygame/wasm_patches.py
