for sure, just when the player is prompted to play the hands, the first hand works fine and then the second doenst work.

Hey @primal cipher!

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

primal cipher
normal silo
#

Can you give the output when this issue happened?

#

How do I reproduce the bug?

primal cipher
#

Your hand: ['10', '10'] ( 20 )
Dealer's hand: ['10', '???'] ( 10 )
Do you want to hit, stand, double down or split? split
Your first hand: ['10', '8'] ( 18 )
Do you want to hit, stand or double down? stand
Your second hand: ['10', '10'] ( 20 )
Do you want to hit, stand or double down? stand
Do you want to hit, stand, double down or split? stand
Dealer's hand: ['10', '8'] ( 18 )
You win!

#

in the code I uploaded I made it so that the deck is only 10s and 8s so its easy to get splits

normal silo
#

What is the expected output in this case?

primal cipher
#

Your hand: ['10', '10'] ( 20 )
Dealer's hand: ['10', '???'] ( 10 )
Do you want to hit, stand, double down or split? split
Your first hand: ['10', '8'] ( 18 )
Do you want to hit, stand or double down? stand
Your second hand: ['10', '10'] ( 20 )
Do you want to hit, stand or double down? stand
Do you want to hit, stand, double down or split? stand
Dealer's hand: ['10', '8'] ( 18 )
You win!

normal silo
#

The first thing to note is that you don't have only 1 player hand after splitting, nor do you have only 1 player total.

#

But the code only works with 1 hand and 1 total.

primal cipher
#

Does that mean I need to find a way to break out of the loop after the second hand?

primal cipher
normal silo
#

If you want to always end to the game after two stands after splitting.

#

Do you want the game to end after the two while loops in the split branch complete?

#

That is, do you want to go out of the main loop?

primal cipher
#

yes I do, so then then the dealer's hand will be shown.

normal silo
#

Then you can use a break. A break will jump out of the loop you are in immediately.

#

If you have nested loops then it will break out of the inner-most loop you are currently in.

primal cipher
#

yeah i was playing around with that just there was so many indents that i didn't now where to place that break.

normal silo
#

After the two split while loops.

#

After those complete the game is suppose to be done.

#

If you make the indentation the same as those two loops then the break is definitely not inside them, so it will break the outer while loop, the main one.

primal cipher
#

it works thanks

Hi all, I'm currently developing dominoes game using Turtle module, and this is the splash screen.

#

That's pretty noice 👍

devout crater
#

if you were to make an rpg with several different attacks, would you make one universal flexible attack function or one function per attack?

eternal vessel
#

I'd do one per

dawn quiver
#

I'd do per. The only universal thing might be the required data of each attack like the name, damage or cost. Nothing but data.

devout crater
#

alright thanks

#

got so dang tired of classes that im gonna try to make everything functions. probably going to end in disaster, wish me luck

believe it or not as of now it functions

my functions do retain data also

You don't have to

You can use @dataclass magic

devout crater
#

wait

#

this is just like a struct?

#

is this really it

dawn quiver
#

Syntactically, to a C struct, sure somewhat

devout crater
#

what are they for

#

whats the difference between this and a regular class

dawn quiver
#

They offer some boilerplate

devout crater
#

new term to me

dawn quiver
#

Pre-written code

devout crater
#

like what

dawn quiver
#

So you don't have to go through typing def __init__(self, blah, blahblah) anymore

devout crater
#

oh okay

#

great

#

thanks

dawn quiver
#

And, as you saw the pretty printing

devout crater
#

beautiful

#

all i've wanted

#

i'd probably be using another language if things wasn't so easy to install in python, so it's nice to see my least favorite things about it be circumvented

dawn quiver
#

You tend to realize you can build pretty much anything you want with major languages nowadays, there are extremely good libraries/frameworks barely anyone knows about

#

I only recently learnt about this new UI framework, barely anyone knows about it (compared to the most popular ones out there for Python like Tkinter etc.), but its out of this world

#

I posted a bit of what I did using it in #user-interfaces , it lets you use flutter through Python, you can even use it for Web UI

devout crater
#

oh cool

#

now

#

for dataclasses

#

how do i make a variable that's not part of the init

#

is it just this

image.png
#

and can i add methods

dawn quiver
#

yes, and yes

devout crater
#

oh wow ofc you can

image.png
#

can you add one outside the class definition?

dawn quiver
#

Sure, it won't be a part of the class

devout crater
#

oh you mean like that

#

i like those

#

but i've been wondering if it's less efficient

#

not that it matters for pygame of all things

#

but doesn't it redo all the data instead of the bits you want to change

dawn quiver
#

Not really, it does very little, and only really makes a difference when creating an instance

devout crater
#

okay

#

next question

#

do i have to import a class if i want it to be a part of the dataclass

#

normally you can just use whatever kind of argument you please

dawn quiver
#

depends on what you mean
If you want to make a class to a dataclass, you just stick the @dataclass on top of it

devout crater
#

no i mean more like

#

i have a parent class and a child class

#

in different files

#

normally if i want the parent object pointer as an attribute of the child class i can do that without importing the parent class file

#

but with dataclasses it looks kinda like you have to explain what each and every thing is

#

define the types i mean

dawn quiver
#

I get what you mean, you want to know how you can avoid circular type hints

#

There's a type in the child class's file that you cant import to the parent class because it is already being imported

devout crater
#

not really

#

i mean the parent class is being imported to the child class so the child knows what it is

dawn quiver
#

In that case you can just do

from dataclasses import dataclass
from typing import Any

class A:
    my_attr: Any

from a import A

class B(A):
    def method(self):
        print(self.my_attr)
dawn quiver
devout crater
#

sorry for the confusion, i don't mean intheritance

#

when i say parent-child i just mean one object is within the other

dawn quiver
#

I see, so you mean like

from dataclasses import dataclass

@dataclass
class Child:
    parent: Parent
devout crater
#

exactly

dawn quiver
#

You dont need to import it, you can use Any like I suggested above

devout crater
#

oh i see

#

thank you

Do you plan to develop games using Python?

Hi all, I’d like to know:

Are there any Python Devs who know the language well (have experience in coding) and who would like to try Video Game Development for the first time?

We’re currently developing a new web platform for creating and sharing indie games. It uses python. If you fit the description and are curious about Game Dev what would be the blocking point/ the difficult point in your opinion, that prevented you from giving the Game Creation a shot previously?
If you don’t care about Game Dev in Python you can also tell me why. We’re curious to know about you. 😉

Soo, i have this script right now. Now, the plan was that the green rectangle would dissapear after i hit it. Reason for this is because it should give me a speed boost for 5 seconds. Though, when i tried wich just making it dissapear, it gives an error

it says: File "c:\Users\jens4\OneDrive\game.py", line 145, in <module>
main()
File "c:\Users\jens4\OneDrive\game.py", line 131, in main
if player_x < speedboost_x + speedboost_width and player_x + player_width > speedboost_x and player_y < speedboost_y + speedboost_height and player_y + player_height > speedboost_y:
UnboundLocalError: local variable 'speedboost_x' referenced before assignment

And i am not entirely sure what it means. Can someone help and explain it to me?

but if you global speedboost_width, speedboost_height in your main function it works

To me using free assets is like cheating

i'm professional asset stealer, people will never guess what i used to make "my" assets

I'm just not very creative so it's always some blocky sprites

i just hope my large folders of unfinished stolen stuff will never leak

#

i'm starting to use ai to make hd textures with pixel art now, and then a bit of photoshop

#

like, different dimension me can give good results

eternal vessel
#

I started pixel art with Minecraft texture packs so that's all of my knowledge when it comes to art

eternal vessel
fallow finch
#

yea, with minecraft you realize 16x16 textures can make very insane things

#

before minecraft i was making calculator games with 8x8 black and white sprites

#

i'm probably in top 5 best 8x8 sprite makers in the world

eternal vessel
#

Dang only 8x8 that's rough

fallow finch
#

with animation it can be cool

#

and games on calculator are generaly made in asm so we can emulate grayscale, someone made a thing to have 9 levels of grayscale on a software not supporting it

eternal vessel
#

I mean I guess the black and white aspect was probably worse that the size

eternal vessel
fallow finch
#

this one is a famous calculator game

#

(not made by me lol)

#

it's using 8 levels of grayscale, made with flickering in asm

eternal vessel
#

I couldn't even make something look that nice with colors

fallow finch
#

in 8x8 sprites there's generaly one way to make the things that is better than the rest

#

while in minecraft/16x16 textures there's already 100 different ways to make a cool thing

#

like, try to make a key in 8x8, you'll see

eternal vessel
#

Yeah true you're more limited with 8x

#

Idk maybe I should try 8x I haven't made anything in Pygame in a bit though

In which game engine can u make a 3d game while coding in python?

#

a 3d engine in which u can import ur own 3d models

#

ik i need to retopo and texture them first

fallow finch
#

godot can also use python but idk if its relevant for 3d

#

you can maybe take a look at something more low level, like ursina3d or even use raw opengl via pyopengl/moderngl, pywavefront exists for loading 3d models in python for opengl

so i have saved players data in as an array of values and saved it in a txt file, but i dont know how to extract those value now.

The data saved in the file looks like this btw:
[10, 5, 7, 5, 5, 5, 5, 50, 20, 50, 50, 50, 50, 50, 50, 50, 50, 50, 50, 50, 'Jes', 5, 280, 15, 'B', 12, 'King Slayer', 'None', 'Leather', 'Arquebus', 9, 'None', 'Copper', 'Roginata', 4, 'None', 'Leather', 'Mongolian Bow', 3, 'None', 'Silver', 18, 5, 2, 23, 2, 3, 20, 'Iron Shield', 4, 50, 'Vabok', 0, 1, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 1, 0, 0, 1, 1, 'None', 'None', 'None', 'None', 'None', 'None', 'None', 'Fire Bomb', 'None', 'None', 'None', 'None', 'None', 'None', 'Fire Dust', 'None', 'None', 'None', 'None', 'None', 'None', 'None', 'None', 'None', 'None', 1, 58]

#

im guessing i should split the variable based on where there are ","s, but im not sure on how to do that?

#

Correction:I have figured it out

fallow finch
#

you can use a python dict as json or pickle, that's a way better solution

#

your array also looks like its a mess, a dict would be way better

boreal holly
cursive veldt
fallow finch
#

user can modify the files easily to do what they want

#

and you most likely don't want to make a parser that never returns an error

#

for user data pickle is maybe the best choice, it's binary and not human-redable format

cursive veldt
#

yeah I can agree the reliability of parsing would be better with one of those modules

cursive veldt
fallow finch
cursive veldt
#

someone can create their own python object, with malicious code. then store that file instead of your save file

#

and then you end up loading a malicious object into your game

fallow finch
#

using a proprietary encrypted binary format ?

cursive veldt
#

nah

#

I'd just avoid deserializing user input

#

not that it really matters here just wanted to see what your reasoning was for saying it was safer

fallow finch
#

still, making your own parser for text files is not safe

cursive veldt
#

yeah from a reliability perspective I agree

round obsidian
dawn quiver

it uses a language called "GDscript" which the developers (or someone) says is "loosly based on python" but to be honest, it has a lot of similarities to python to just be "loosly" based

and you can also use c#

dawn quiver
fallow finch
#

so is it actually a good choice for this

# obtuse imp Thank you!

keep in mind arcade isnt very popular so you wont get support for using other libs with it just like pygame

#

and its also a "spoon" of pyglet; its built on it but only allows 2d graphics while pyglet can do 3d

obtuse imp
#

So it's not very complex at all

fallow finch

fallow finch

for easy things everything already exists

obtuse imp
#

ok thank you

fallow finch
#

like, if i want to load other image formats with pillow and use it in arcade, i have no idea of how to do this

next sun
# fallow finch stackoverflow has like 5000000 posts about pygame

Look if you are talking about ease of accessing help in both the libs have appropriate help system for them. Arcade has lots of examples in its own docs "for easy things". I can't argue about the already commonly faced problem of pygame users already present on stackoverflow, but if you follow arcade by docs and see its examples, you won't need to lookup everything on stackoverflow like most of the people do when they don't read the docs.

fallow finch
#

yea for arcade itself i guess, but for using it with other libs, there's a lot more stuff on the net

#

also pygame is really good for compat with other libs because of how you can convert surfaces to numpy and do the reverse thing as well

#

while arcade is based on pyglet so everything is an opengl texture

#

that's just an example

next sun
fallow finch
#

that was just an example, but pillow can load most existing image formats

#

i use jp2 a lot on my own but its not very relevant here

next sun
fallow finch
#

i use this for loading the files on my own btw

#

not something to do every frame, just for loading some image formats

#

but that was just one example of thing you can do with pygame you cant do with arcade

#

also, even if its just for 2d games, arcade doesnt keep all the features of pyglet, so i don't see a reason to not use pyglet directly

next sun
fallow finch
#

ah yes, you can actually use pillow with it

#

so this example wasnt relevant

next sun
# fallow finch also, even if its just for 2d games, arcade doesnt keep all the features of pygl...

Arcade has its own features, you are installing arcade to use as main arcade and not pyglet as the main lib. Also arcade has some really cool features that pyglet doesn't has inbuilt like https://api.arcade.academy/en/latest/api/particle_emitter.html , you can use arcade.particles to create some cool effects like fireworks(https://api.arcade.academy/en/latest/examples/particle_fireworks.html#particle-fireworks) fyi the example also shows using both arcade and pyglet together, although pyglet is only used for its pyglet.math.

next sun
#

Once you learn to read docs those 50+ upvotes(depciting common probelms) stackoverflow pygame posts becomes irrelevant when seeking for help. Although for some uncommon use cases pygame's already made large post history can help you but in arcade for uncommon use cases you can checkout the arcade discord(even for common cases its alright) for immediate help or make your own stackoverflow post.

brisk yew
# next sun Type conversions in game dev are not that desirable because it results in perfor...

Nope, that usually is an optimization, mby not for tiny surface and not something used very commonly, but getting a reference instead of a copy is really fast. Also more niche stuff ig and idk much about arcade, but pygame has GPU support, the complete API although available is still in development for a more stable release, but you can use it already, not like sth's gonna explode or anything (srsly, it's stable already for the most part, in terms of it working properly)

fallow finch

pyglet has gpu support + loading gpu compressed textures, something pygame can't do

"better" is obviously a rather broad concept, it's hard to assess that without knowing specifics, like better in what area, ease of use, arcade might be better, I truly don't know about that, performance wise, I'd really think pygame is faster in that regard. some other area, who knows...

fallow finch
#

but sdl2 is faster

#

i was saying arcade doesnt use the compressed texture support from pyglet, but i'm not very sure

fallow finch
next sun
#

FYI there is also performance comparison present on the link I mentioned.

brisk yew
#

Oh, sure, I was just saying that since you responded to a question asking about better alternatives

fallow finch
#

yeah but it's not pygame sdl2 mode

#

comparing pygame's software rendering with opengl makes no sense

#

pygame's sdl2 mode IS faster than arcade/pyglet, it uses directx on windows for example, and pyglet doesnt

brisk yew
#

Also there's pgzero, in terms of beginner friendliness, I'd say it's really good at that, expanding won't be easy at all tho

fallow finch
#

also...

image.png
#

its not just about sdl2, they don't really know pygame

#

makes no sense too

image.png
brisk yew
#

I don't get how pygame is better at logic stuff tbf, but sb made a video rather recently comparing a couple libs, like pygame, renpy, another lib (might've been arcade) and pygame with GPU and the results were pretty clear on pygame w/ GPU being the fastest, now, it mby wasn't a really comprehensive test, they drew a ton of sprites moving around and rotating until FPS dropped

fallow finch
next sun
fallow finch
#

but sdl2 mode from pygame uses a compat layer for graphics engine (aka directx on windows), while the others just use opengl

#

so yes, it's faster

brisk yew
#

Also like, who'd ever need 50k stationary sprites, that really calls for optimizations already

aside pygame newbies on stackoverflow

#

saying you have to do this with pygame makes no sense

next sun
next sun
brisk yew
#

also pygame has support for an alpha channel, you don't necessarily need a colorkey

next sun
#

Yea some things might need to be updated there

brisk yew
#

I can try, I'll now try to do that conversion tho

next sun
brisk yew
#

hmm, slight issue, that test repo don't have images where they're supposed to be

fallow finch

here's what i get with the amogus test on my gpu(nvidia 3070)

top and bottom of the image

next sun
brisk yew
#

yep

#

also the code doesn't run due to that

#

(obvs)

next sun
#

The code should run though because the png is saved as screenshot on that path and the csv is written by the PerformanceTiming class. I will try to run it when I get on computer.

#

is there some specific error you are getting?

brisk yew
#

interesting, it actually did run tests, it failed at generating graphs

#

(or after that)

next sun
#

@brisk yew uncomment the logic and then run it, then it should not give the error

brisk yew
#

and it died again

is that why it was commented out?

frail ether
brisk yew
#

so there's like a dedicated dc server for pygame...
what's the exact issue you're facing?

#

where do you make it change the direction upon reaching the boundary?

frail ether
#

I want it to move left when it reaches the right boundary and move right when it reaches the left boundary

brisk yew
#

where do you change its direction

frail ether
#

like inside the code?

brisk yew
#

yeah

frail ether
#

57

brisk yew
#

what is this?

image.png
#

and I don't see how it changes the direction

frail ether
#

I've set the X axis to 370 and Y axis to 120

#

at line 18

#

there is a function enemy which draws the bird on screen

#

on line 50 I've made a variable birdX += 0.3 for the movement of the bird

brisk yew
#

okay, you need to invert it once you reach a boundary

frail ether
#

YES

brisk yew
#

your x direction is 0.3

#

you're not changing that

frail ether
#

How do i change it?

#

ohhh

#

there is birdX += 0.3

#

that's why it's moving in the positive direction

brisk yew
#

you need to change 0.3 to -0.3

frail ether
#

kk

#

Thanks broo

#

!!!

frail ether
#

My bird is at the cenre

#

in the beginning

#

So, how can I make it move in the start

#

'cause birdX += 0.3 and birdX -= 0.3 are under if conditions

#

So, How can I make it move

brisk yew
#

that's not what I meant

#

you always have bird_x += bird_x_dir

#

all you do once you hit a boundary is do bird_x_dir *= -1

#

at the start bird_x_dir is defined as bird_x_dir = 0.3 before the main loop

frail ether
#

what is bird_x_dir?

brisk yew
#

x direction of the bird

frail ether
#

what is dir

#

It's not in my code

brisk yew
#

yeah

#

dir is short for direction

frail ether
#

So, I should make it?

brisk yew
#

yeah

frail ether
#

k

frail ether
#

Like just for clarity

#

You can copy paste my code here and make changes in it

brisk yew
#

you can name it birdXDir to conform with your naming style btw

frail ether
#

ohh

#

So, I can move the bird before the main loop

#

And, then add that if condition inside the main loop

#

right?

brisk yew
#

the if condition only the change the direction

#

and ig adjusts x so it doesn't get into a loop of changing directions constantly

frail ether
#

k lemme run and check it

brisk yew
#

also none of those comments are in the slightest bit useful or necessary

frail ether
#

k

brisk yew
#

except for #Slingshot and #Bird ig (you should add a space after # as per PEP 8 too)

frail ether
#

okk

frail ether
#

sill it's not running

#

Can you just make changes here

#

And, send me

#

plz

#

My brain is freezed

brisk yew
#

This is about how I'd approach this for you:

import pygame

pygame.init()

screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Bird Invader")

# Slingshot
slingshot = pygame.image.load("slingshot.png")
slingshot_x = 370
slingshot_y = 480
slingshot_x_change = 0

# Bird
bird = pygame.image.load("bird.png")
bird_x = 370
bird_y = 120
bird_x_dir = 0.3

running = True
while running:
    screen.fill("white")

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                slingshot_x_change = -0.3
            elif event.key == pygame.K_RIGHT:
                slingshot_x_change = 0.3
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                slingshot_x_change = 0

    slingshot_x += slingshot_x_change
    bird_x += bird_x_dir

    if slingshot_x < 5:
        slingshot_x = 5
    elif slingshot_x > 735:
        slingshot_x = 735

    if bird_x < 5:
        bird_x = 5
        bird_x_dir *= -1
    elif bird_x > 735:
        bird_x = 735
        bird_x_dir *= -1

    screen.blit(bird, (bird_x, bird_y))
    screen.blit(slingshot, (slingshot_x, slingshot_y))

    pygame.display.flip()
#

may or may not work, can't test, don't have images, but it should work

frail ether
#

what is flip?

#

pygame.display.flip()

brisk yew
#

yeah, that updates the display

#

similar to update

frail ether
#

Should I set the bird_x_dir variable to 0?

brisk yew
#

no?

#

this code should be copy, paste, run, see if it works

frail ether
#

It's highlighting the variable

#

'cause it does not exist in the code

brisk yew
#

which variable?

frail ether
#

bird_x_dir

brisk yew
#

just copy and paste the entirety of that code over your existing one...

frail ether
#

I've done that

#

And, it's highlighting the bird_x_dir

#

and showing error

brisk yew
#

where exactly?

#

cuz it's clearly defined...

frail ether
#

oh wait

#

the bird_x_dir variable is 0.3 in your code

#

got it

brisk yew
#

yeah

frail ether
#

BROO

#

it works

#

Thanks!

#

Can you please explain what you just did in the code

brisk yew
#

start from there, 3 msgs

frail ether
#

@brisk yew Can you explain me the function of bird_x_dir *= -1

brisk yew
#

it reverses the direction pretty much

#

like bird_x_dir = bird_x_dir * -1

frail ether
#

SO if bird_x_dir = 0.3

#

then it's like 0.3*(-1)

#

right?

#

!e

print(0.3*(-1))
frank fieldBOT
#

@frail ether :white_check_mark: Your 3.11 eval job has completed with return code 0.

-0.3
frail ether
#

which is -0.3

#

So, it will be in reverse direction

#

mhmm got it!

i put a help thing in help channel, but basically, some of mine are just randomly triggering 🥲

#

hi, i have a piece of code id like to include in a loop but im not sure how? Basically im rolling two dice and i later on, if answer is 'else' i want to repeat the entire rolling process in the loop. Here is the 'dice roll' part:

# 
import random

print('rolling dice...')
##### dice 1
animal_list1 = ['sheep', 'sheep', 'rabbit', 'rabbit', 'rabbit', 'rabbit','rabbit','rabbit','pig','pig','cow','wolf']

# pick a random choice from a list of strings.
dice_1 = random.choice(animal_list1)
print('dice 1:',dice_1)

for i in range(0):
    animal = random.choice(animal_list1)
    print(dice_1)


  
##### dice 2
animal_list2 = ['sheep', 'sheep', 'rabbit', 'rabbit', 'rabbit', 'rabbit','rabbit','rabbit', 'pig', 'pig', 'horse', 'fox']

# pick a random choice from a list of strings.
dice_2 = random.choice(animal_list2)
print('dice 2:',dice_2)

for i in range(0):
    animal = random.choice(animal_list2)
    print(dice_2)


#append to list  
dice_results = []
dice_results.append(dice_1)
dice_results.append(dice_2)

print('you rolled: ',dice_results)
#

i am then trying to either get a pair and only ending up with one which works, and if the roll was NOT a pair, roll again. Here is how i got it to only end up with one if it IS a pair.:

duplicates = []
for value in dice_results:
    if dice_results.count(value) > 1:
        if value not in duplicates:
            duplicates.append(value)
        else:
            print(dice_results)

print(duplicates)

#

Is the light source an overlay? Or an area where shadow overlay is not applied? How does it work?

marble jewel
#

its a black translucent surface drawn over the gameworld, then each light source changes the alpha value of the pixels by using BLEND_RGBA_SUB blit mode

# 
    def glow(self, pos, size, intensity, step = 1):
        
        size = (int(2 * size), int(size))

        cache_string = f"{size}, {intensity}, {step}"
        glow_surf = self.glow_cache.get(cache_string)
        
        if not glow_surf:

            glow_surf = pygame.Surface(size, flags = pygame.SRCALPHA)
            glow_rect = glow_surf.get_rect()
            ellipse_rect = glow_surf.get_rect()

            while ellipse_rect.height > 0:
                
                ellipse_surf = pygame.Surface(ellipse_rect.size, flags = pygame.SRCALPHA)
                pygame.draw.ellipse(ellipse_surf, (0, 0, 0, intensity), ellipse_surf.get_rect())
                
                glow_surf.blit(ellipse_surf, ellipse_rect.topleft, special_flags = pygame.BLEND_RGBA_ADD)

                ellipse_rect.width -= (4 * step)
                ellipse_rect.height -= (2 * step)
                ellipse_rect.center = glow_rect.center

            self.glow_cache[cache_string] = glow_surf

        self.light_layer.blit(glow_surf, pos - (size[0] // 2, size[1] // 2), special_flags = pygame.BLEND_RGBA_SUB)

#

Nice, thanks

#

You had mentioned about going inverse square route for the radial intensity, but that must be more intensive no?

#

Instead I think it can have just three concentric circles of varying brightness

#

Ellipses*

marble jewel
#

doesn't seem to be, I've got some code from some people on the pygame discord which I'll mess with, worst case I can just transform a circle and scale it to be the same size as an ellipse

#

also I cache all the surfaces I make

#

so once I create the light of a particular size and brightness i can just blit it again, no need to recreate it

Hey Guys, relatively new to Python and trying to use it to generate tile maps for me using a Voronoi diagram. However, I keep running into the issue that I can't ' the 'smooth' the edges of my Voronoi with LLoyds algorithm because it has these points on the side that don't have an edge on them. I was wondering if you guys would have any pointers on how to fix because i would like to use these to generate maps for a game im working on

#

here is my code

#

import scipy.spatial

Generate 50 random points

points = np.random.rand(1000, 2)

Compute Voronoi diagram

vor = Voronoi(points)

Plot Voronoi diagram

fig = voronoi_plot_2d(vor)
plt.show()

Apply Lloyd's algorithm to smooth the diagram

for i in range(10): # repeat 5 iterations
centroids = []
for region in vor.regions:
if len(region) == 0:
continue
indices = region[:-1]
vertices = vor.vertices[indices]
centroid = np.mean(vertices, axis=0)
centroids.append(centroid)
vor = Voronoi(centroids)

Visualize the smoothed Voronoi diagram

fig, ax = plt.subplots(figsize=(6, 6))
voronoi_plot_2d(vor, ax=ax)
plt.show()

#

here is the voronoid i make before i 'smooth' it

here is after

you don't need any caching with it and its a lot faster

#

a lot of games have a "hardware acceleration" setting, so you can switch between software rendering and gpu rendering, and gpu mode can have more visual effects for example

it should be return not 0 <= self.x <= self.width
or return self.x >= width or self.x <= 0

Technically, you can get full graphics with stdlib, since it includes ctypes.

more importantly it includes tkinter, ez graphics

you can do opengl with ctypes?

A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.

versed aurora
#

also the 3d rotation matrix

normal silo
versed aurora
#

yeah but that's a matrix, idk how to make than an equation ::(

normal silo
#

A matrix represents a transformation. To apply the transformation, you multiply to the matrix with what you want to apply it to.

versed aurora
#

well yeah but unless i use np i'm not gonna be able to do that
idk

normal silo
#

You can do it in plain python.

versed aurora
#

also this is probably the first time i've actually needed to collapse functions in vscode

normal silo
#

*Btw, you can do the matrix multiplication out by hand to figure out what the equations for the individual x, y, and z values are.

#

Then you can use that instead of having any matrices in your actual code.

#

(It turns out that matrices are really nice to work with though (chaining transformations together), so it's probably worth having some matrix class)

if your game isnt online i don't really recommend sql for this, you can use pickle to store a python object in a binary format, like, a .dat file stored in appdata is a common way to store player scores

ok

cosmic swallow
fallow finch
#

yea, freetype can draw the text directly

#

i'm not sure for pygame.Font, but pygame.freetype can

also

1 - you should really implement oop at this point because your code isnt really readable

#

2 - why you have 2 different loops

cosmic swallow
cosmic swallow
fallow finch
#

mh alright

#

but keep in mind having more than one loop isnt the right way to use pygame or any graphic window app

you should implement states and not execute the same code depending on the state

all i need right now is it just works

blit to button_surface at 0, 0

fallow finch
#

if (0, 0) doesnt work, its an issue with the surface

#

be sure to blit at the end of the loop

#

so nothing blits on it

Tysm that actually worked

if you want to not make surfaces for each line of text

cosmic swallow
#

okay

#

uhh i see another issue

fallow finch
#

pygame.Font is a limited version of freetype

#

yea ?

cosmic swallow
#

probably because there are a few loops?

the you lost section doesn't seem to blit anything anymore, only time.sleep works

brisk yew
#

pygame.Font.render now supports newlines in pygame-ce

cosmic swallow
#

this part

#

the # check for win or loss below it

#

what can i do?

fallow finch
#

i don't know if your code is really executed like you're expecting

#

but wtf is that time.sleep() after the flip()

#

you should never use sleep inside your loop because it freezes everything

#

pygame.time.Clock exists and can make the game tick to force 60 fps for example

#

ah you're already using a clock

#

so yea whats those sleeps

cosmic swallow
#

so it doesn't turn off instantly

#

oh right

#

wait

fallow finch
#

just use something to pause the game using the clock, or a timer to achieve what you want

#

but no sleep() inside a game loop

#

the best at this point is to really implement states, using one loop

#

pause can be a state (keeping whats displayed in the window) and then you revert to game state

cosmic swallow
#

i fixed it

yo how do i create a timer using time module

timer shouldnt stop the code from working

Does arcade or any other python game engine support blitting in isometric natively? (i.e. without implementing our own transform functions)

fallow finch
#

just make the right sprites and blit them in the right order

fallow glade
#

Does not answer my question.

fallow finch
#

do you want to use normal textures and transform them to make isometric sprites ?

fallow glade
#

No, only the engine part. So vectors defined in x-y cartesian plane are transformed into coordinates fitting an isometric view.

fallow finch
#

you want to use 2d or 3d vectors ?

hushed vine
# fallow finch pygame ?

No i, I'm making a game using tkinter and I need a timer, I tried using time.sleep() but that stopped the program

brisk yew
fallow glade
#

To blit it such that it is in an isometric plane, the visual coordinates will be some other x, y

#

This can be achieved by multiplying the position vector with a transformation matrix

#

It's simple stuff, but when done on a lot of objects things can get expensive, so if there's an engine which implements this conversion natively, preferably in a lower level faster language

fallow finch
#

yea but it's just about math, so you're asking if arcade has the math functions to draw isometric map ?

#

arcade is based on pyglet which is made in pure python, with "bindings" for opengl and all the backend stuff

#

you can make some math functions in C if you want, but vectors should already have a lot of methods for transformation, you can probably already do this

fallow glade
#

Yes I can, I was just wondering if it already exists

fallow finch
#

i don't really know arcade/pyglet vectors, just pygame vectors

fallow glade
#

Not to needlessly reinvent the wheel and all

fallow finch
#

and pygame vectors have a huge amount of transformation/calculation functions, all written in C

How make a game

Hey guys,

I'm looking to improve my Python skills, and I'd love to work on a project that I enjoy. I've always wanted to create a 2D game similar to Worms, with realistic physics and environments, but with more complexity and additional statistics.

My question is, which library would be best for this project? Would PyGame be sufficient, or are there better alternatives? I need advanced physics for the objects and terrain in my game. Thank you 🙂

next sun
# topaz copper Hey guys, I'm looking to improve my Python skills, and I'd love to work on a pr...

Define what advanced physics are you talking about? Arcade has inbuilt support for physics engine, if it is your main concern. It also depends if your knowledge of physics covers the game mechanics, if thats the case physics engines won't bother/hinder you much. You can always try out the options(libraries) and see which suits your needs better. If you are just looking to improve your skills in python, then I guess the library won't matter much. Although I have to say this arcade was/is designed/being designed to be user/beginner friendly.

Good day people! I have 2 keyboards plugged into my PC and i want my Python program to be able to receive input only from one of them. So either i need to somehow tell the program to read only from one device or block input from all unwanted devices. What would be the proper way to make either of these work?

proper peak
#

(oh, and this will only work on windows, and require an alternative implementation on other systems)

lament carbon
#

So, you're basically trying to get "the natural look" of the keyboard message, which i guess is just a bunch of 0 and 1, and that's how you can distinguish one keyboard from another?

proper peak
#

Kind of like that (though the format of the message is standardized, so it's not like you need to suffer decoding it)

lament carbon
#

Doesn't look like this library works for me, or works at all

#

The idea with raw input data seems like it could work, but i have no idea how to get raw input in Python

#

If any raw keyboard message contents data about where it came from, all i need is to get it just once

#

Actually i'll need it every time a key is pressed on the keyboard

proper peak
#

looking more into the API, it goes like:

  • the program registers that it wants to get raw inputs for some devices via RegisterRawInputDevices
  • it then starts getting, for a specific window (!), via WindowProc, WM_INPUT messages.
  • on recieving such a message, a program can then pass the handle in it to GetRawInputData to get the actual input data
#

so it needs to be a gui application, I think, because a window is needed??

lament carbon
#

Please, God, not the window

#

I can think of a few more ideas which seem really bad, but could work as well

#

Such as, making the other keyboard send some Non-English chars, maybe Chinese or Arabic

#

And then read these on usual key.char

#

But here's the question, how do you set different keyobard layouts on different keyboards

#

Is it doable with Windows tools or...?

proper peak
#

maybe there's another function to do it system-wide, but mostly I think you can't have different layouts

lament carbon
#

It looks like making this work can take a few times the size of my initial code i wanted to work with, or i am just not experienced enough to deal with this

#

Maybe it is relatively-easy doable with MIDI ports, i don't know

#

But they all are the same problem, referring to each device as individuals, or referring to any device in the first place

proper peak
#

it'd take quite a lot of work, yeah

#

I tried to implement it just now, and I got almost to being able to call RegisterRawInputDevices before I realised I'd also need to make a window and poll for messages from it

lament carbon
#

Do people take commissions around here? I mean, even if i can't get it to work i still need it to

proper peak
#

well, we forbid recruitment on the server under rule9

#

anyway, here's what I managed to do until giving up:

# 
import ctypes
from ctypes.wintypes import DWORD, USHORT, HWND, UINT, BOOL

user32 = ctypes.WinDLL("user32")

# https://learn.microsoft.com/en-us/windows/win32/api/winuser/ns-winuser-rawinputdevice
class RAWINPUTDEVICE(ctypes.Structure):
    _fields_ = [
        ("usUsagePage", USHORT),
        ("usUsage", USHORT),
        ("dwFlags", DWORD),
        ("hwndTarget", HWND),
    ]
user32.RegisterRawInputDevices.argtypes = [ctypes.POINTER(RAWINPUTDEVICE), UINT, UINT]
user32.RegisterRawInputDevices.restype = BOOL

# https://learn.microsoft.com/en-us/windows/win32/inputdev/using-raw-input#example-2
ridev = RAWINPUTDEVICE(
    usUsagePage=0x01,  # HID_USAGE_PAGE_GENERIC
    usUsage=0x06,  # HID_USAGE_GENERIC_KEYBOARD
    # hopefully this one isn't important:
    # dwFlags = RIDEV_NOLEGACY # adds keyboard and also ignores legacy keyboard messages
    hwndTarget=0,  # this should be the window id I think, and I don't have a window, welp
)
user32.RegisterRawInputDevices(ridev,1,ctypes.sizeof(RAWINPUTDEVICE)) # got a 1, yay - that means success

(Or you can do other neat hacks like get the window handle to the console window)

# 
[in, optional] hWndParent

Type: HWND

A handle to the parent or owner window of the window being created. To create a child window or an owned window, supply a valid window handle. This parameter is optional for pop-up windows.

To create a message-only window, supply HWND_MESSAGE or a handle to an existing message-only window.

(CreateWindow (not Ex) also has the parameter)

how do you delay a function while somthing else is running in a while-loop?

normal silo
#

Measure the current time at the start, then in each iteration of the loop, measure the current time and get the difference between that and the start time. If it's greater than the delay amount, execute the function.

#

The function is not executed at the same time as other things are happening. If you want that then you will need some multithreading*.

trying to change the position of the window in pygame but it doesnt do anything :[

import pygame
import os

pygame.init()
screen = pygame.display.set_mode((100, 100),pygame.NOFRAME)
clock = pygame.time.Clock()
run = True
tick = 1

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    screen.fill((0,0,0))
    os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (tick%100+5,tick%100+5)
    pygame.display.update()
    clock.tick(30)
    tick = tick + 1

pygame.quit()

no error, window position just stays as being in the center

proper peak
#

no way SDL would monitor changes to the environment variable while the program is running.

lime raven
#

kind of surprising there isn't any way to change the window's location

proper peak

and it seems there isn't, which is weird

so I guess pygame just doesn't expose it?

might be worth an issue or pull request 🙂

is win32gui a library

#

oh yeah it is my bad

proper peak
#

(it installs multiple packages including win32api)

lime raven
#

it seems like i already have those

proper peak
#

quite possible

#

the call is win32gui.MoveWindow(hwnd, x, y, width, height, True) (it simultaneously moves and resizes the window, and the True makes it repaint immediately)

#

the interesting part is hwnd, which is the window id of the window to do it to

lime raven
#

do you think i should go ahead and open one

proper peak
#

yeah, I googled pygame "SetWindowPosition" and didn't find it either

proper peak
#

wait a minute @lime raven

#

and then, apparently

video.Window.position can set the position. It's an experimental API, and may change.

#

so I guess it is implemented?? just nobody knows?

but it does actually work

#

Thanks, check out some of the older videos if you're interested in how the game has been evolving over the last few months

dawn quiver
#

I did actually

#

I'm thinking of implementing potential lighting for my isometric game too, but I'd love to know how you got the ellipses to light up/clip certain parts of the map and keep the rest dark.

#

And are you scaling each individual surface up and then rendering it? The player moves around the map really smoothly for it to be in the number of pixels it appears to have been drawn in

marble jewel
#

its just one big light layer that is black with a 255 alpha, I then blit lights on top of it and subtract alpha so the end result just eats away the darkness

dawn quiver
#

I then blit lights on top of it and subtract alpha

That makes sense, do you use any special flags when blitting to achieve that? iirc you couldn't subtract certain alpha from certain parts of the surface otherwise

marble jewel
#

I don't scale the surfaces themselves, the entire canvas is 560 x 315 and then I scale that using the pygame.SCALED flag

#

the alpha subtract is pygame.BLEND_RGBA_SUB

dawn quiver
#

If that's the case I'd have assumed the movement to look more like this (because the diagonal movement would be limiting in the few number of pixels)

dawn quiver
marble jewel
#

I'm not sure about the movement, the player does rotate to face the mouse so maybe it just looks smoother idk

Hmm, well, cool game anyways

hey there! need some help with something pretty simple that I can't really figure out as of yet

So, I have this system where I feed scenes as backgrounds for my game, this then runs through the game-loop and prints the images in order - my problem current is that tiling the images requires looping, and that (as far as I can tell) really gobbles up some performance. I'm not exactly certain as to how I can avoid this, any ideas? adding any layers basically drops around 5-6 frames each.

game loop

def run_game(screen:screen, running = True):

    def loop(*obj:object):
        while running:
            screen.tick()
      
            ...  
      
            kb.borderEx(screen, p1)
            kb.jumpEx(p1)         

            p1.animChara()
            p1.delayEx(20)
            p1.BulletEx(1000)
            
            bg.draw_moving_scene(p1, screen)

            # debug
            ...

            # bullet handling
            bullet._group.update()
            bullet._group.draw(screen.SCREEN)
 
            pg.display.update()

    # objects
    p1    = fighter(config='assets//chara//fighter1.json',img='assets//images//warrior//Sprites//warrior.png', coord=(0,400)) 
    bg    = scene(screen, 0, 'assets//images//background//bg2.png','assets//images//background//middle1.png','assets//images//background//front1.png', 'assets//images//background//tree.png')
    ...
#

the concerned layer class:

class layer(object):
    def __init__(self, img:str, show:bool,  drawspeed:int, screen:screen,  title_index:int = 0, imgsize:tuple = (1280, 720)) -> None:
        self.shift_amt   = 0
        self.tiles       = math.ceil(screen.WIDTH / imgsize[0]) + 1
        ...

    def draw(self, screen:screen, scale=True, coord=(0,0)):
        if abs(self.shift_amt) > self.WIDTH:
            self.shift_amt = 0

        # Laggy due to looping as far as I can tell
        for i in range(0, self.tiles):
            super().draw(screen, scale, coord=((coord[0] + i * self.WIDTH), coord[1]))
#

and the scenes this gets fed in:

class scene():
     ...
    def __init__(self, s:screen, mode, *layers) -> None:
        ...
        func_path = {
            0 : usemode_FMBE,
            1 : usemode_FMB
        }

        self.mode     = mode
        self.p_layers = func_path[self.mode](s, layers)

        self.screen_size = (s.HEIGHT, s.WIDTH)
        self.border      = s.WIDTH/2

        #assigns the individual images to class objects (self.effect etc), pls clean
        for image in self.p_layers:
            ...
    def draw_moving_scene(self, player:fighter, screen:screen):

        if player.is_past_border():
            self.effect.shift_amt += self.effect.drawspeed
            self.back.shift_amt += self.back.drawspeed
            self.middle.shift_amt += self.middle.drawspeed
            self.front.shift_amt += self.front.drawspeed

        if player.is_before_border():
            self.effect.shift_amt -= self.effect.drawspeed
            self.back.shift_amt -= self.back.drawspeed
            self.middle.shift_amt -= self.middle.drawspeed
            self.front.shift_amt -= self.front.drawspeed

        self.back.draw(screen, coord=(self.back.rect.x - self.back.shift_amt, self.back.rect.y))
        self.middle.draw(screen, coord=(self.middle.rect.x - self.middle.shift_amt, self.middle.rect.y))
        self.effect.draw(screen, coord=(self.effect.rect.x - self.effect.shift_amt, self.effect.rect.y))
        player.draw(screen, False, (player.rect.x, player.rect.y))

And raw_input was used before?

ye

how did you learn and get so good

#

do you know a better way to learn then code academy

woven canopy
#

Random youtube tutorials.

Also for future reference, on the right side where it's got the bit about "Traceback (most recent call... line 27

#

that gives you a solid inidication of where the issue is. Also while you are using code academy, it doesn't give very good error messages

placid wing
#

ok

for example in idle. Instead of a traceback with just a line number it tells me

i started using vs code yesterday

# 
  File "~battleship.py", line 28, in <module>
    guess_row = int(raw_input("Guess Row: "))
NameError: name 'raw_input' is not defined```
placid wing
#

but for courses i must use online code academys IDE

woven canopy
#

which might help steer you to precisely what the problem is. raw_input must be some code-academy function

placid wing
#

but code academy's courses are not even that good if you dont pay

woven canopy
#

are you taking a class that requires CA?

placid wing
#

no

#

i am learning with just CA

#

no classes

woven canopy
#

Aah, well CA can help you get the basics so I'm not going to steer you away from it. Personally I did a 4 and a half hour YT course back when Covid hit to stave off boredom.

When it comes to trying to run the code myself, raw_input() is an issue, but that might be something integral to Code Academy

placid wing
#

do you know the youtube course you did,

#

if so it might be worth trying.

woven canopy
#

aah so raw_input was a python2 thing
