Btw is pygame exe does only work in windows?

[crisp junco]

Never tried using my .exe on different OS's, so I might not be right to ask this

Though I think it should work on different OS

[dawn quiver]

Sorry one more question can I use pygame and kivy? At the same time

[crisp junco]

I've seen some guys using pygame with tkinter(I don't know abt kivy), though I've never myself used both of them together

[dawn quiver]

Thanks

Ooooooooh nice

[carmine vapor]

Can I have some help with some Pygame code?
The basket is not showing up for some reason

import pygame
import random
import math

# initialize pygame
pygame.init()

# create screen
screen = pygame.display.set_mode((800, 600))

# title and logo
pygame.display.set_caption("Apple Picker")
icon = pygame.image.load('apple_logo.png')
pygame.display.set_icon(icon)

# Basket
basket = pygame.image.load('basket.png')
basketX = 370
basketY = 480


# basketX_change = 0

def basket():
    screen.blit(basket, (basketX, basketY))


# game loop
running = True
while running:

    screen.fill((217, 230, 255))

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


    basket()
    pygame.display.update()

this is my code and I can't figure out why my basket isn't showing up

[torn flume]

    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                xPos = xPos -5
            if event.key == pygame.K_RIGHT:
                xPos = xPos + 5
    screen.blit(Atla_Idle, (xPos, yPos))
    pygame.display.update()

How do i make it so i dont have this like clone thing. pls help, i've been stuck here forever. ;-;

pls ping me if you can help please. 🙏

[tawny abyss]

@torn flume You are only updating the character

You need to update your back drop too

[torn flume]

but i never set a background

[tawny abyss]

Well that sounds like a problem now doesn't it

[torn flume]

oh, so what would the code be to update the backdrop

[tawny abyss]

(Whatever the name of your map is).fill(BLACK)

screen = pygame.display.set_mode((WIDTH, HEIGHT))
You should have a line like this somewhere

And whatever you named it

Call the fill function for it in your update function

[torn flume]

this is my top code

[tawny abyss]

Okay good just do screen.fill(0,0,0)

[torn flume]

ok thanks

says black is not defined, (sorry for the inconvenience im a new programmer)

[torn flume]

so do i do .fill(BLACK) or .fill(0,0,0)

[tawny abyss]

Do the 0,0,0

Or do a string "Black"

I set black as a variable

[tawny abyss]

Put another set of brackets around it or do "black"

[torn flume]

it still clones. ;-;

[tawny abyss]

Show code

[tawny abyss]

My guy

You update it ONCE in your entire code

Do it in your update function

Everytime your character updates

The screen should too

[torn flume]

oh ok

im dumb

the code under that is text engine, i have it updating. ;-;

@tawny abyss so is there a code for background update, and one for sprite update, or are they the same

[torn flume]

nvrmind i figured it out on my own

[blissful depot]

is there a good tutorial for Pygame RPG?

because I want to do an RPG style(ish) game

mostly just the top-down movement

but yeah

[potent ice]

tile based?

[blissful depot]

sure

[potent ice]

https://github.com/bitcraft/pytmx + the Tiled editor might be a good start

[blissful depot]

what exactly does that mean, though?

(I mean it by tile based)

[potent ice]

https://python-forum.io/attachment.php?aid=773

[blissful depot]

nice!

https://image.slidesharecdn.com/pythoningamedevelopment-140610033704-phpapp01/95/python-22-638.jpg?cb=1402371627

It really helps you get started quick with making a world.

[blissful depot]

ok

thanks!

is there a tutorial for making a topdown game?

[potent ice]

No idea. I'm sure there are some tutorials for pytmx that can be helpful.

[blissful depot]

ok

[potent ice]

Tiled maps have layers. You can for example create a layer for teleport locations placing some named object. It will have a position in the world

Fetch information about these objects in your game code and use them.

There is a lot of tricks with these maps

Pretty sure it has some collision support

@blissful depot first hit on google : https://www.trccompsci.online/mediawiki/index.php/PyGame_RPG

Might be better ones out there

[blissful depot]

oh thx

can you do collisions or no?

[potent ice]

No idea to be honest

The README says "Support tile colliders"

[blissful depot]

huh

ok

thanks!

[dawn quiver]

I finally got it working. Sorry I never came back. I reset my PC an redone everything cause it was a mess.

[dawn quiver]

I need help when I checked my game exe it detected a virus anyone have a fix?

[whole coyote]

It's a known problem with packagers for Python.

@mental lichen

u mean game development sdk!

then unity for free

[oak pier]

Which is one good gaming library for getting young kids involved in cpding python?

[mental lichen]

Unity is not in mobile

[mental lichen]

Are u a young kid? LoL

[oak pier]

ig i am 16 rn

[ocean belfry]

bro! that was unnecessary @mental lichen

[oak pier]

i have worked with java but first time in python

[mental lichen]

Just reliving stress trying to make u happy :-(

[ocean belfry]

python is widely used for 2d game development and a new 3d engine ia just arrived on the markett! U can wait avfew months after all the bug fixes u may try it

[ocean belfry]

what are u asking a game development sdk for creating games on android

?

[mental lichen]

Good gaming engine which can run on mobile

[ocean belfry]

Its wud be really ez if u have past exp in java

[oak pier]

I also intend to teach my classmates and they are probably not familiar with coding at all

[ocean belfry]

there is no game engine for android!! u can create a game on unity and publish it on android

[oak pier]

Was looking for something simple to start

[mental lichen]

There are some

Discord should have slack like thread feature

[dawn quiver]

hey guys
I have a lives counter
displaying on left top
code is like this

def show_lives(x,y):
    lives = font.render("Lives:" + str(lives_value), True, (34,139,34))
    screen.blit(lives, (x,y))
if lives_value == 0:
    playerX == 2000
    enemy1Y == 2000
    enemy2Y == 2000
    enemy3Y == 2000
    enemy4Y == 2000
    enemy5Y == 2000

now if I want to stop this from appearing how do I do it?

[crisp junco]

What I used to was that I changed the x,y coordinates to something like 10000,40000 so that it doesn't appear in the main screen, though this isn't the best practice.

live_x = your_val
live_y = your_val
show_lives(live_x,live_y)
if died:
  live_x = 10000
  live_y = 40000

[crisp junco]

btw the syntax doesn't looks correct

if lives_value == 0:
'''
Why are you using the == operator? It's used to check if two things are equal. I suppose you want to use = instead of ==
'''
    playerX = 2000 #Should be like this 
    enemy1Y = 2000
    enemy2Y = 2000
    enemy3Y = 2000
    enemy4Y = 2000
    enemy5Y = 2000

[dawn quiver]

I want to do that but the problem is that the boundary function stops it from going out

instead it just stays at the edge of the screen

and it looks really weird

     #boundaries
    if playerY <= 0:
        playerY = 0
    elif playerY >= 536:
        playerY = 536
     ```

this one

is there a way to stop this function whenever the lives==0 is achieved?

[crisp junco]

You can do something like

if lives_value != 0 
   #boundaries
    if playerY <= 0:
        playerY = 0
    elif playerY >= 536:
        playerY = 536

[dawn quiver]

oh

yes

I will try that

[crisp junco]

lemme know if that doesn't work

[dawn quiver]

omg thank you so much it worked

I was stuck in this for so long

dont know why I didnt think of that

but the problem is that when the game ends, only the player drops out

not the enemies

[crisp junco]

You mean that only the player goes off the screen and not the enemies?

@dawn quiver

[dawn quiver]

yes

the player drops down

but the enemies keep going

[crisp junco]

Ok DM me

and share your full code

[dawn quiver]

ok

[dawn quiver]

is react-native the best thing to use to make a game for the app store ? I was considering using unity too

[manic moth]

hello, I'm just testing out multiplayer system in pygame. I have 2 scripts server and client. I'm just trying to move 2 squares , each controlled by 2 different people in the same LAN. I am using the rect class in this way in my client.py:

pygame.draw.rect(window, (50,70,50), (self.x, self.y, 50, 50))

But it always crashes as soon as I run a client. The error I get in client.py is Invalid rect argument. Can someone please help me with this.

[potent ice]

Quick glance on the docs it seems the 3rd argument is a Rect : https://www.pygame.org/docs/ref/draw.html#pygame.draw.rect

The error message is complaining about the rect argument specifically even (3rd argument)

[manic moth]

yes, i read that too

but

[potent ice]

It expects a rect, but you are passing a tuple

[manic moth]

I have another project in which I use a tuple

and that works fine

it also accepts a tuple, if not a Rect object

[potent ice]

with the same pygame version?

[manic moth]

ummm

lemme check

yes, I didn't update my pygame library ever since I installed it

so, it's the same version, I'm sure

lemme paste the full code though

server : https://paste.pythondiscord.com/iceberezon.py
client : https://paste.pythondiscord.com/ujuvaqazef.rb

[potent ice]

Maybe this is something for the pygame community discord? I just follow the official api docs

Here : https://discord.gg/h8ujJGCcq3

[manic moth]

Thanks a lot

[visual island]

hi

is there anyone use panda3d

[potent ice]

Probably quite a few people, yes. Either directly or through Ursina

[blissful depot]

I might learn pygame zero

cuz it is a lot easier

especially since I'm not the best coder

but is it ok to talk about that here?

[potent ice]

Sure. It's simple enough

Another alternative is arcade. It's between pygame and pygame zero in difficulty and has lots of tutorials, examples and other resources.

[analog barn]

hey everyone first day on pygame here, I LOVE IT. I am wondering if this function I made will work fast enough to use as a surface resizer for when the player is resizing the window? ```py
def scale(child_surface, comparison_surface, percentage):
"""scale the dimensions of a surface based on a percentage of
the height of a comparison surface. Preserves aspect ratio of
child."""
child_rect = child_surface.get_rect()
child_aspect_ratio = child_rect.width / child_rect.height
# this is the value that the rectangle will be scaled to
comparison_height = comparison_surface.get_height()
child_rect.height = percentage * comparison_height
child_rect.width = child_aspect_ratio * child_rect.height
# resize the child surface to its' scaled rectangle
child_surface =
pg.transform.scale(child_surface, child_rect.size)
return child_surface

Say if I had .... 100 + surfaces

[severe saffron]

well it will be basically instant

you slightly overuse variables but that's just a style thing

although

hmm

i can't think of a faster way

i'd just try it out

[analog barn]

Ok, let me try...

[severe saffron]

if any of the surfaces are duplicates, you don't need to call it on the duplicates afaik

[analog barn]

Ohh I didn't know about duplicates, that could save a lot of processing power

[still pumice]

guys i have a question if ya wouldnt mind answering
if you were to play a top down endless shooter what things would you like?

[analog barn]

safe-rooms where you can access an inventory, plan, take a breath etc would be a cool idea

If you were makign a big map

Oh and use monsters / PVE that makes the player need to move around in combat, like a zone that moves around and does damage to the player, or some sort of ranged attack

[potent ice]

It really depends on the scope of the project 😉

If it's a shooter I'd focus on the shooting part. Types of bullets/weapons/synergies vs various enemy types

[analog barn]

Ahh ok so I DON'T have to run my game at 1200 fps lol ```py
while True:
# tick game clock, set max frame rate
self.clock.tick(self.vars.max_fps)
# get seconds passed since last frame (delta time)
dt = self.clock.get_time() / 1000.0

        self._check_events()
        self.ship.move(dt)
        self._update_screen()

[white vector]

I been trying to make 4 dimensional minesweeper, pretty much with brute force and kivy.
Is there a better way to iterate through surrounding cells in a bounded 4D matrix than:

for i in range(I-1,I+2):
 if 0<=i<W:
  for j in range(J-1,J+2):
   if 0<=j<X
    for k in range(K-1,K+2):
     if 0<=k<Y
      for l in range(L-1,L+2):
        if 0<=l<Z and [i,j,k,l]!=[I,J,K,L]: cell_data.update( process_cell(i, j, k, l, 'command') )

because 4D matrix processing looking clunky at this point and it's only gotta iterate through up to 80 cells, and i remember the zen of python telling me flat is better than nested...

don't judge my compact syntax, either, or my slight Horror Vacui style of coding

[wicked torrent]

can we make 3d games in pygame

or any other module in python

[white vector]

what about 4D?

or ND?

[dawn quiver]

how do i make a app in python

[dawn quiver]

You can either use kivy, tkinter or something...

[crisp junco]

Do you mean like converting .py to .exe?

[dawn quiver]

yes

[crisp junco]

https://www.youtube.com/watch?v=UZX5kH72Yx4

watch this

[dawn quiver]

doesnt work for me
bruh

[crisp junco]

Did you paste all the dependencies into the dist folder?

@dawn quiver

[dawn quiver]

ill try after sometime

u mean the pygame library zip and the python interpreter?

@crisp junco

[crisp junco]

No

[dawn quiver]

then what are the deps

[crisp junco]

Are you using any images in your game?

[dawn quiver]

no

just pure pygame shapes

[crisp junco]

So is your game just code dependent ,ain't using you using anything extra like audio files,videos,images?

[dawn quiver]

no

[crisp junco]

ok

[dawn quiver]

pure pygame

[crisp junco]

then

Open cmd

[dawn quiver]

ill do it later am busy

[crisp junco]

ok

Here are the steps tho:

1. Open cmd
2. type pip install pyinstaller
3. type cd your_script_parent_folder_path (like C:\Game Folder)
4. type pyinstaller --onefile --windowed yourscriptname.py

[dawn quiver]

ok

[dawn quiver]

error

[crisp junco]

Send the script

https://paste.pythondiscord.com/

[crisp junco]

Oh I see, I guess you're going into the build folder, you needn't go there; Go to the dist folder therein you'll find an .exe just run it

[rugged locust]

hi

[dawn quiver]

ok

bruh

Bad image error

[crisp junco]

Send the code @dawn quiver

https://paste.pythondiscord.com/

[dawn quiver]

ok

https://paste.pythondiscord.com/raw/qecekemubo

sry if light mode

[dawn quiver]

bro???

[crisp junco]

Yeah I'll try making an exe of it

[dawn quiver]

ok

[crisp junco]

It's working

I did pyinstaller --onefile --windowed scriptname.py

[dawn quiver]

i didnt do thst

lemme try

[crisp junco]

Here's the link

https://drive.google.com/file/d/11nNYoeA_mV2znsenMNpsI3A7kB3Vvtd0/view?usp=sharing

You can download it

[dawn quiver]

ok

Thank you 😃

[crisp junco]

If you want an icon for the game then download an icon.ico(Note the .ico extension)
Type pyinstaller --onefile --windowed --icon=icon.ico scriptname.py (Make sure the icon is in the same folder as of script)

[crisp junco]

You're welcome 🙂

[dawn quiver]

is there any virus

@crisp junco

[crisp junco]

Nope

What's happening?

Windows has a habit of detecting any unverified app as a trojan

[dawn quiver]

didnt run it yet

just double checking

im doing builds meself

now

[crisp junco]

@dawn quiver don't worry it isn't a trojan you can check about it in google

Fine, as you wish

[dawn quiver]

I told about ur exe

DONE BOOM

worksss

[crisp junco]

It's not specific to my exe

[dawn quiver]

ok

btw thank you 🤝

[crisp junco]

you're welcome

[analog barn]

Any reason why I would be getting hung up for about 30 seconds on pygame.init()? It was working instantly last night, now it takes almost 30 seconds to get past pg.init() (the first line of code in the game.)

After that it works normally

[dawn quiver]

What is pygame

how to convert py to exe

[analog barn]

pygame is a 2d game engine for python, and there are lot's of way to convert to exe, here's one https://www.geeksforgeeks.org/convert-python-script-to-exe-file/

BTW I fixed the init() I had to add exlusions in my antivirus for the Python install, and the project folder

now it works again stangely

oh wait nvm it's broken again LOL

import pygame
import time
start = time.time()
pygame.init()
print(f"Runtime: {time.time() - start}")
``` ```txt
pygame 2.0.1 (SDL 2.0.14, Python 3.9.0)
Hello from the pygame community. https://www.pygame.org/contribute.html
Runtime: 40.19267535209656

[neat adder]

Pysintaller and py2exe work i believe

[still pumice]

yeah i just used py installer too

[neat adder]

i have had problems with PyInstaller though, not sure why but i could just never get it to function for me.

it sucks because not everyone using my script has Python installed and, or, does not know how to invoke Python.

[still pumice]

if you have any assets they need to be in the exe file location too

unless you declare where it is

[neat adder]

wait, you can bundle multiple scripts together?

[still pumice]

Yeah

i think

[neat adder]

oh cool.

[exotic hawk]

noice

[analog barn]

Ok I figured out that pygame.joystick.init() was causing the delay .... unplugged and reconnected keyboard to fix ....

[dawn quiver]

hi

ursina is pretty cool

you should check it out

https://pypi.org/project/ursina/

[untold bramble]

How do I perform texture atlasing via python?

[potent ice]

You can pre-build them with pillow at least

make one big empty image and paste in sections from other images

[white vector]

how do you make two windows in kivy, short of a complicated threading network?

alternatively...

How do you make a grid of grids consistently fit in-screen, but maximum size available for all sub-cells to be perfectly square?

I had an algorithm that worked if two or four dimensions were filled, but would maximise the smaller side instead of the larger side if one or three of the dimensions were size 1

plus it was hard to read to troubleshoot, or understand

I'll pull it up to show youse

[normal silo]

@white vector Kivy does not support multiple windows, and having multiple would require some crazy complex multi-subprocess handling.

[white vector]

ah, so I'll stick to grid of grids, theen

the buttons will probably need reading glasses to see tho

eww I opened the file and it's from when I started obfuscating things

and it has code art

fixing this up gonna be a chore

[normal silo]

Ah the code digger. Digging a hole from left to right with that indentation.

[white vector]

ok I found it

def build_board(self): 
  w,x,y,z,n = self.wxyzn
  self.title = "(: | "+str(n)
  b,h = 1500, 1000
  Window.size = (w*y*h/(x*z), h) if w*y >= x*z else (b, b*x*z/(w*y))
  Window.bind(on_resize=self.on_resize)
  Window.position = 'auto'
  self.board = Grid4D(w=w, x=x, y=y, z=z, app=self)
  return self.board

Is the slightly less obfuscated version.

[normal silo]

May I recommend using iterators? To keep that loop nesting to a minimum? https://docs.python.org/3/library/itertools.html

[white vector]

(w*y*h/(x*z), h) if w*y >= x*z else (b, b*x*z/(w*y))
Is the offending algorithm

[normal silo]

Example: for x, y, z in itertools.product(a, b, c) where a, b and c are ranges, e.g. a = range(1, 2).

[white vector]

but code art....

would that work in list comprehension, too?

for making a 4D matrix

[normal silo]

yes

[white vector]

t = [[[['' for _zi in range(z)] for _yi in range(y)] for _xi in range(x)] for _wi in range(w)]; v = [[[[0 for _ in range(z)] for _ in range(y)] for _ in range(x)] for _ in range(w)]

for that ^

[normal silo]

in python when you do a for ... in ... loop you are looping using an iterator. You can create iterators, including ones that loop over a multi-dimensional structure.

[white vector]

but creating that multi-dimensional structure?

[normal silo]

python's built in itertools library to there to help with that.

[white vector]

well now the new func is

    def get_revealed_texts(self):
        import itertools
        w,x,y,z,n = self.wxyzn; t = [[[['' for _zi in range(z)] for _yi in range(y)] for _xi in range(x)] for _wi in range(w)]; v = [[[[0 for _ in range(z)] for _ in range(y)] for _ in range(x)] for _ in range(w)]
        for I,J,K,L in itertools.product(w,x,y,z):
                                                     for i in range(-1, 2):
                                                             if i+I in range(w):
                                                                    for j in range(-1, 2):
                                                                          if j+J in range(x):
                                                                               for k in range(-1, 2):
                                                                                   if k+K in range(y):

[normal silo]

You can do the rest too

[white vector]

but if i+I in range(w):

there's ffilters

[normal silo]

no problem

[white vector]

or would I place them inside the nest and chain them?

oooh

[normal silo]

for I,J,K,L,i,j,k,l in itertools,product(w,x,y,z,range(-1,2),range(-1,2),range(-1,2),range(-1,2)): maybe make the range(-1,2) a variable.

oh one sec

it's technically not as efficient this solution, but the ranges are small anyhow range(-1,2) so it does not really matter.

inside the for loop you can still do the if checks

but all in one if statement

if i+I in w and j+J in x and k+K in y and l+L in z:

make w, x, y, z ranges.

e.g. w_range = range(w)

or just type out range(w) instead.

[white vector]

or...

    def get_revealed_texts(self):
        import itertools
        w,x,y,z,n = self.wxyzn; t = [[[['' for _zi in range(z)] for _yi in range(y)] for _xi in range(x)] for _wi in range(w)]; v = [[[[0 for _ in range(z)] for _ in range(y)] for _ in range(x)] for _ in range(w)]
        for I,J,K,L,i,j,k,l in itertools.product(*[range(this)for this in[w,x,y,z]],*[range(1,-2)for _ in range(4)]]):
         if i+I in range(w)and j+J in range(x)and k+K in range(y)and l+L in range(z)and self.is_bomb[I+i][J+j][K+k][L+l]:v[I][J][K][L]+=1
         wi,xi,yi,zi = I,J,K,L
         if self.is_bomb[wi][xi][yi][zi]   :
                       t[wi][xi][yi][zi] = self.ICONS[-1]
         elif          v[wi][xi][yi][zi]==0:
                       t[wi][xi][yi][zi] = ''
         else:         t[wi][xi][yi][zi] = str(v[wi][xi][yi][zi])
        self.text,self.values=t,v

[normal silo]

excellent

[white vector]

now for the t variable generation

[normal silo]

I recommend using a shape variable e.g. t_shape = [a, b, c, d]

replace a, b ... with the shape

[white vector]

a shape?

[normal silo]

yeah so t has a shape

it's a multi-dimensional array filled with ''

[white vector]

yeah, it's a 4d matrix of text

[normal silo]

yeah so it's shape is 4d

each element is the length of that axis

which in your case right now is range(z), range(y), etc

[white vector]

and that would initialise a new text element?

[normal silo]

not yet

[white vector]

hang on brb a few secs

[normal silo]

it just specifies what shape we want

the algorithm will use that to generate the actual array we want.

(as an argument / create a new function)

something like def create_empty(shape): which returns t

(can also be re-used to create v, but fill it with zeros instead via a fill_value argument).

[white vector]

i never heard of no shape object

[normal silo]

it's just a list

each value specifies the array's range on a given axis

for example a 1d array that has 10 elements would be shape = [10].

a 2d array that is 5 by 4 would be shape = [5, 4]

[white vector]

    def get_revealed_texts(self):
        import itertools
        w,x,y,z,n = self.wxyzn
        t,v = ('',0)for _,__,___,____ in itertools.product(*[range(_t)for _t in[w,x,y,z]]) 
        for I,J,K,L,i,j,k,l in itertools.product(*[range(this)for this in[w,x,y,z]],*[range(1,-2)for _ in range(4)]]):
          if i+I in range(w)and j+J in range(x)and k+K in range(y)and l+L in range(z)and self.is_bomb[I+i][J+j][K+k][L+l]:v[I][J][K][L]+=1
          wi,xi,yi,zi=I,J,K,L
          if self.is_bomb[wi][xi][yi][zi]:t[wi][xi][yi][zi] = self.ICONS[-1]
          elif v[wi][xi][yi][zi]==0:t[wi][xi][yi][zi]=''
          else:t[wi][xi][yi][zi]=str(v[wi][xi][yi][zi])
        self.text,self.values=t,v

would that work?

[normal silo]

unfortunately not

[white vector]

thought I'd try :P

[normal silo]

create a new function named def create_filled(shape, fill_value).

then t = create_filled([w, x, y, z], '').

[white vector]

!e ```py
import itertools
print([[i,j,k,l]for i,j,k,l in itertools.product(range(4),range(4),range(4),range(4))])

[frank field]

You are not allowed to use that command here. Please use the #bot-commands channel instead.

[white vector]

rood

[normal silo]

The idea I had in mind was to create a recursive solution to this.

def create_filled(shape, fill_value):
  if len(shape) == 0:
    return fill_value
  result = []
  for i in range(shape[0]):
    result.append(create_filled(shape[1:], fill_value))
  return result

then t = create_filled([4, 4, 4, 4], '')

You can see an example in the bot-commands channel, i posted it there

def create_filled(shape, fill_value):
    if len(shape) == 0:
        return fill_value
    return [create_filled(shape[1:], fill_value) for i in range(shape[0])]

@white vector Better?

How about even less lines?

def create_filled(shape, fill_value):
    return fill_value if len(shape) == 0 else [create_filled(shape[1:], fill_value) for i in range(shape[0])]

[white vector]

it still looks longer than the original

[normal silo]

yes, but it's generic

you can give it any shape and any fill value, so you can use it for both t and v

=> less code

[white vector]

hmm, what if I imported this from my cursed module?

def self(n=0):
    n+=[__import__('os').system(""),2,print(f"accessing frame: {n+1}")][1]
    f=lambda*a,**k:None
    def b(c):
        try:raise Exception("\x1b[31mTop level frame, cannot reference.\x1b[0m")
        except Exception as e:fr=e.__traceback__.tb_frame;return[{(fr:=getattr(fr,'f_back'))for _ in range(c)},fr.f_code][1]
    f.__code__=b(n);return f
f = lambda a,b:print(a)or self()(b,a+b)
f(0,1)

[frank field]

You are not allowed to use that command here. Please use the #bot-commands channel instead.

[white vector]

okay see #esoteric-python cos that's kinda it's home

although I still like my list comprehension for initialisation

[normal silo]

Well smaller is nice, but at some point it requires the reader to know more and more python concepts, and I like to avoid too many for clarity / simplicity.

[white vector]

I like to avoid clarity

[normal silo]

Ah you trying to make it obfuscated?

[white vector]

yeah but it's lower priority than efficiency

and i just figured out a way to initialise t and v together

[normal silo]

Well most efficient solution to all this would be using numpy.

[white vector]

but then that's an import, hence a dependancy

it's bad enough it depends on kivy

and itertools

[normal silo]

so you want pure python max speed?

[white vector]

yarr

[normal silo]

ok, because numpy makes the speed of course in an entire different ball park.

This is a bunch of values.
Is there a way to compress this information in a way it can still return the relevant 4-tuple given the index v?

or have I achieved it?

other than replacing every , with , ofc

or even better, is there a way to generate consistent but mostly unique colours for 81 different options?

uh, no, you got a random tab in the middle of the sentence

You should unindent the second line, or start with a newline to get consistent indents when Asteroid.__doc__ is printed

[woven nacelle]

Hello

Could someone help me with translating a set of points from world to screen? I'm using python's Turtle module for plotting....

I'm currently using the 'planar' geometry library but I need to stop using it and implement the Affine translations myself...

[white vector]

what world?

to what screen?

[grim abyss]

the DOOM levels

[white vector]

and what set of points?

[grim abyss]

@white vector https://github.com/InZane84/WADdle-Plot-CLI

the points for the vertexes in the levels

I can't properly setup scaling. I don't know how to compute the scale for each level.....

I'm trying to translate the points to a Turtle canvas

^ those few lines are what is currently allowing the points to even show up....

[white vector]

I'm probably getting sidetracked but

            linedefs = {}
            linedefs['start_point'] = line[0]
            linedefs['end_point'] = line[1]
            linedefs['flags'] = line[2]
            linedefs['type'] = line[3]
            linedefs['tag'] = line[4]
            linedefs['frontside_num'] = line[5]
            linedefs['backside_num'] = line[6]
            linedefs['number'] = i
            self.lines.append(linedefs)

you made this like this for readability?
cos it took me longer to read it than if you'd've left out the "middle-man variable"

[grim abyss]

Yes, for readability....

[white vector]

same deal here, but inconsistent, slightly

            side_dict = dict()
            side_dict['x'] = side[0]
            side_dict['y'] = side[1]
            side_dict['UPPER'] = side[2].strip("\x00")
            side_dict['LOWER'] = side[3].strip("\x00")
            side_dict['MIDDLE'] = side[4].strip("\x00")
            side_dict['SECTOR'] = side[5]
            self.sides.append(side_dict)

[grim abyss]

yup

[white vector]

and \x00 == \0

[grim abyss]

ahhh

[white vector]

plus it's less readable, at least for me, as the middle-man variable is rather distracting

[grim abyss]

recommendations on structuring it better?

The relevant code is in the Plotter class

[white vector]

so move the last line to the start, and open brackets to a series of newline separated "string": object

[grim abyss]

I cut my teeth on Python with this application. The design is..... 'archaic'

[white vector]

line up the colons for readability, as the eyes like to move in straight lines

[grim abyss]

oh, of course

[white vector]

you want me to show you what I mean?

[grim abyss]

I got you on lining up the colons

[white vector]

cos you don't need to init a dict before writing data to it, you can init it with the data and init it within the argument list to append

[grim abyss]

show me, change one of the classes. Like the LineDef class...

[white vector]

my_array.append({
  "a"  : 1,
  "b"  : 2,
  "foo": "bar"
})

[grim abyss]

oh

[white vector]

that sort of syntax, so for the LineDef...

I'm leading you to a way to use one function to handle both of those situations, btw

a slightly alternate syntax...

self.lines += [{
  'start_point'  : line[0],
  'end_point'    : line[1],
  'flags'        : line[2],
  'type'         : line[3],
  'tag'          : line[4],
  'frontside_num': line[5],
  'backside_num' : line[6],
  'number'       : i
}]

[grim abyss]

yeah, that looks ALOT better......

[white vector]

looks neater than linedefs linedefs linedefs linedefs...

it shouldn't be that hard to figure out how to apply that to the side_dict thingy

[grim abyss]

so wait... the "+=" can be used to 'add' to a list?

i didn't know that

[white vector]

yeah, the __add__ attribute of a list can concatenate two lists

[grim abyss]

oh ok

so yeah, i'm going to re-write the whole app since the code is so old...

[safe glacier]

what does it mean to initialize a mixer?

[white vector]

just to show you a bit of internals...

list.__add__(
 self.lines,
 [{
  'start_point'  : line[0],
  'end_point'    : line[1],
  'flags'        : line[2],
  'type'         : line[3],
  'tag'          : line[4],
  'frontside_num': line[5],
  'backside_num' : line[6],
  'number'       : i
 }]
)

so the list's method of adding is applied to these two lists, and the result is returned to self.lines by appending an = sign to the + sign

[grim abyss]

gotcha

[white vector]

while i < self.size/30:
python has a way to deal with this without needing a i+=1 every iteration
for i in range(-(-self.size//30)):

it even initialises it for you

[grim abyss]

i see

[white vector]

SideDefs has the same __init__ method as LineDefs

you can make a parent class, then make these classes inherit from that

ok i hanged my browser accidentally so i can't view the code...

class _ParentDef:
  def __init__(self, *args):
    ...

class LineDef(_ParentDef):
  def make_lines_go_brr(*args):
    ...

class SideDict(_ParentDef):
  def side_dict_whatever(*args):
    ...

instead of defining the same __init__ twice

[grim abyss]

interesting

[white vector]

you can define it once and pass it to all that use it

alright i found the bit

        self.scale = planar.Affine.scale((.175))
        self.bbox = planar.BoundingBox.from_points(self.level.vertex_vectors)
        self.offset = planar.Affine.translation((-self.bbox.center))
        

so what's wrong with that? it looks like it does the job.

@grim abyss you trying to make it independant of the planar module?

[grim abyss]

the scale is hard-coded and I need to compute it for each map and also want to be independent of the planar module, yes.

the problem is....I don't understand what planar is doing to be independent of the lib

[white vector]

use an IDE, select the word Affine in planar.Affine and depnding on the IDE it might be ctrl-B or ctrl-D

[grim abyss]

there has to be a simple formula to compute a vertex from world to screen...

I know I have to do something with min/max funcs....

and then divide them by the canvas size or something crazy

to get the scaling factor?

[white vector]

okay, let's brreak this down into chewable chunks...
when in doubt coding always start with pseduo-code

[grim abyss]

ok

[white vector]

so write out in english what you want it to do, the input, the constants provided, the expected output, etc...

[grim abyss]

for v in vertexes:
  if v < or > canvas_width and canvas_height:
    compute_to_screen(v)
  v.plot()

or something like that....lol

but i need to check for window changes as well

i'm moving to tk+turtle

of course the plot method wouldn't be attached to the vertex object! lol

these points are in ranges of (-32767,32767)

[white vector]

wdym by compute to screen?

[grim abyss]

i can't plot a (-6000,6000) point to a canvas of size 400x400....well I can but I don't know how to do it

i would need to convert the points to floats as well probably

i can find the center of the map easily enough. If I get the center of the canvas and use that as the center of the map I would just need to scale down?

this has racked my brain for months trying to understand it

I can send you the points for doom level e1m1 and you see if you can use turtle to plot them correctly?

wait let me show you something

@white vector Check this short program out that does what I am trying to do but outputs an image: https://github.com/jmickle66666666/wallpaint/blob/master/drawmap.py

could you explain that code to me in english? lol. My math sucks

[white vector]

I'm stuck at import omg

looks suspiciously like a dependancy

[grim abyss]

it is. it's the omgifol lib

@white vector https://github.com/devinacker/omgifol

[white vector]

so many github links lol

[grim abyss]

and looking at his code is like going to the 3rd level of hell!

yeah i'm deep into github

[white vector]

    if sys.platform.startswith("java"):
        # Jython always uses 32 bits.
        MAXSIZE = int((1 << 31) - 1)
    else:
        # It's possible to have sizeof(long) != sizeof(Py_ssize_t).
        class X(object):

            def __len__(self):
                return 1 << 31
        try:
            len(X())
        except OverflowError:
            # 32-bit
            MAXSIZE = int((1 << 31) - 1)
        else:
            # 64-bit
            MAXSIZE = int((1 << 63) - 1)
        del X

okay you understand this bit?

[grim abyss]

where is that from?

[white vector]

omgifol/six.py

[grim abyss]

yeah I understand the code but it's unrelated to my issue

[white vector]

ok what's your issue?

i can't plot a (-6000,6000) point to a canvas of size 400x400 <- this?

[grim abyss]

yes

https://pasteboard.co/JPD3Ljzh.png and what is this function doing to the points to get them on the image?

[white vector]

old = [4200, -690]
def translate(old):
  new_x = (old[0]+6000)//30
  new_y = (old[1]+6000)//30
  return [new_x, new_y]
new = translate(old)

idk if this is what you're tring to do but to me this is basic arithmetic

convert the points to floats? that's what the floordiv is for so you don't have to

[grim abyss]

floordiv? I never took algebra,geometry, or trig. well i did but I remember NOTHING from it. suffered an injury...

i understand that code you pasted but they have to be within the range of the canvas

[white vector]

wdym?

the canvas is ([0,400], [0,400]), right?

[grim abyss]

yes, so how can you put a point with a value of 12k onto that?

[white vector]

what i made is a unit conversion.
so (-6k, 6k) units to (0, 400) units

what i did was shifted the scale to (0, 12k) by adding 6k then the unit ratio method
*400 // 12k

[grim abyss]

and this "//" is what? floordiv? why by 12k?

[white vector]

so strip it of it's 12k-ness to get to 1 the "number unit" then give it some 400-ness to translate the continuum from 0 to 1 to fill 0 to 400

that's the same as floor( var * 1/30 ), actually, I could probably strip some zeros and common factors

[grim abyss]

i don't understand this

[white vector]

study any science subject, they'll start you off how to use units

[grim abyss]

units?

doom map editors have scaling factors of say 64, 32, 16, 8.... these would be scaling units?

just googled the '//' and now i understand that. i just moved to py3 so.....yeah

[white vector]

so lets call (-6k, 6k) F and (0, 400) S they're just names, like centimeters.

you have values in F, i.e. (-6kF to 6 kF)
where a kF is a kilo-F

You want it in the units your screen uses which ranges from 0 to 0.4 kS

hence if it can be expressed as a unit conversion problem, it can be solved by unit conversion

a // b == math.floor( a / b )

[grim abyss]

i see

that makes sense

[white vector]

that's basic python operators, python2 is outdated forget it exists :P
well that's just my opinion anyway you don't have to listen to me

[grim abyss]

well it does make sense

[white vector]

so what my translate function does is it manipulates the entire scale represented by the variabe (that your input coords substitute into)
so you apply arithmetic operations to both the start and end points so that they match up to the start and end points of your desired destination for the scale

what you do to the start point you do to the end point, etc..
once you have acheived this, the sequence of operations you did is the algorithm you want

[grim abyss]

ok I think I know what you mean. Need to ponder on it

for awhile, lol

[white vector]

ideaally, you need to get a bachelor of science majoring in mathematics, and maybe do a dual degree with IT majoring in something like algorithms.
realistically, look at math.

ponder math

meditate upon math

become one with math, and let math become one with you

[grim abyss]

hahahahahahha

[white vector]

prractice converting between Celcius and Farenheit to start you off, then Miles and Kilometers

etc...

[grim abyss]

self-study is the only way I will learn. University is out of reach for me

[white vector]

the tell me how many meters squared are in a square that is 9000mm by 8000 inches

[grim abyss]

do you know of a good textbook that pertains to this problem?

or good documentation

i don't even know how to calculate that

mathematics is my weakest programming aspect unfortunetly

[white vector]

Once, given any numbers in any related units, you can calculate that, then you are ready to become one with unit conversion

[grim abyss]

"One with unit conversion" LOL what are you some kind of math guru?

[white vector]

https://tenor.com/view/rogue-one-star-wars-chirrutîmwe-donnie-yen-one-with-the-force-gif-15788011

[grim abyss]

lol

[white vector]

just substitute, scale conversion into the explosions, you into the asian lookin jedi, and python into thhe force and there you have it

[grim abyss]

yeah

[white vector]

the next level is uid to coordinates conversion

and back

[grim abyss]

?

how would that even work

that's like converting a orange to an apple and back isn't it?

[white vector]

let's say i've made a matrix, but every element is a different number.
the numbers are in order how you'd read them if they were words on a page.
you are given a number, and the side lengths of this matrix, what are the coordinates of the cell with this number?

[grim abyss]

num + sides = cell ?

why do channels disappear from the list on the left side of the discord app sometimes?

I went to python-general and when I tried to come back here game-development wasn't on the list

[white vector]

you probably have the section minimised

[grim abyss]

i wish there were tabs for channels like irc clients

but how would I get the cell coords?

[white vector]

so the input is your cell id, and a matrix full of abstract objects, and your output will be a tuple of the length == dimensions in the matrix.
so you can visualise it, I'll just map an example matrix with its numbers

a=[[0, 1, 2 ],
   [3, 4, 5 ],
   [6, 7, 8 ],
   [9, 10,11]]

now given the number 7 , and that is a 4x3 matrix, what numbers do I feed this: a[r][c] such that it returns 7?

[grim abyss]

are we starting from 0?

[white vector]

ofc it's python

[grim abyss]

row or column first?

[white vector]

a[row][column]

[grim abyss]

a[1][2]

whoops

[white vector]

that would be [column][row]

[grim abyss]

thats rigth

oh

lol

a[2][1]

[white vector]

there, so how did you get those numbers?

what did you do?

you probably counted the rows first?

[grim abyss]

i indexed into the array via the rows/colums

row is left to right, correct? column is up/down?

[white vector]

you might've traced your finger down the left side of the matrix until you reached the array containing your number?

[grim abyss]

right, there's 4 arrays

[white vector]

if you were observant, you'd notice that the first element of all these arrays are divisible by three

[grim abyss]

i see that, now......

[white vector]

and three is the width of this matrix

[grim abyss]

ok...

[white vector]

so the first element in your target row is three times its index

then you traced your finger across, until you found your number in that array, the index in that array being the remainder of dividing your number by three, right?

[grim abyss]

wait what? "so the first element in your target row is three times its index" ?

[white vector]

the matrix is an array of arrays

so the row is an array

and the index of that row in it's parent array starts with a number that is three times its index in it's parent array

[grim abyss]

i see it now. 6 is the row. +1 is the target..

[white vector]

I'll give you a clue:

7 = 3*2 + 1

[grim abyss]

yup!

8= 6*2 + 1

[white vector]

uh, no it ddoesn't

[grim abyss]

11 = 9 + 2?

[white vector]

yes

[grim abyss]

?

oh

[white vector]

6*2 + 1 = 13

8 != 13

3 * 2 + 1 = 7

3 * a + b = i

so let's start with 1

how do you take three from a number until you don't have enough of that number to takee another three?

it's called modulus and in python that's var1 % var2

so you'll find that 7 % 3 == 1

that's the remainder when deviding 7 by 3

[grim abyss]

yeah

[white vector]

and the dividing the number by three itself, and ignoring the remainder, i.e. flooring it, will give you the other number

hence...

python has an inbuilt metthod for this problem

you don't actually need to use the number of rows even though it's provided

[grim abyss]

ok so you get how many times 3 will go into 7 and the remainder

[white vector]

I could tell you the sky is blue over here as a clue as to where I am, but that would not make it any easier to track my ip address, just an example

[grim abyss]

no it wouldn't

[white vector]

so you only need to use the column and the given number

to make it much easier to visualise what's going on, make a similar matrix that's 10 by 10

then things will suddenly make sense

well, a little bit more

this is building up to doing operations like this for 4-dimensional matrices, which i made an algorithm for

[grim abyss]

i'm starting to get confused, lol

[white vector]

okay we'll get to 4d later, just get a piece of paper and draw numbers from 0 to 99 in a 10 by 10 grid

and contemplate this grid

note that in base 10 system, the first part of the number is its row, the second part is its column

it lines up neatly

that's the 10-times table

[grim abyss]

LOL HAHAHAHAHHA sorry

wow

[white vector]

wait...

[grim abyss]

no that's not a multiplication table...

[white vector]

i have no clue what that's supposed to be but it looks cursed

[grim abyss]

indeed

[white vector]

remove that heresy against Mathematics from my view...

https://tenor.com/view/die-gun-shotgun-deus-vult-gif-17767114

[grim abyss]

hahahahahah

[white vector]

just go left to right counting up, and insert a newline every ten iterations

and start at 0

[grim abyss]

ill pop one out right quick. one sec

[white vector]

!e 3

[frank field]

You are not allowed to use that command here. Please use the #bot-commands channel instead.

[grim abyss]

um yeah, not quite what i need....

[white vector]

okay just look in #bot-commands

[grim abyss]

?

[white vector]

def get_co(self, i, w=0, x=0, y=0, z=0):w, x, y, z, _n = self.wxyzn if self is not None else (w, x, y, z, None); _ = math.floor; return i%w, _(i/w)%x, _(i/(w*x))%y, _(i/(w*x*y))%z
def get_index(self, *args, **_wxyz):
        if len(args) == 2: wx, yz = args; w, x, y, z = self.wxyzn[:-1] if self is not None else (_wxyz[this] for this in _wxyz); (i, j), (k, l) = get_2d_co(wx, w, x), get_2d_co(yz, y, z)
        else: i,j,k,l = args; w,x,y = self.wxyzn[:3] if self is not None else (_wxyz['w'],_wxyz['x'],_wxyz['y'])
        return i + w*(j + x*k + x*y*l)

I just pulled these steiaght from my 4D minesweeper game

@grim abyss

[grim abyss]

yeah right. no way in hell i'm parsing that lol

[white vector]

this was from before i knew of floordiv

hence....

get_co = lambda i, w, x, y: i%w, i//w%x, i//(w*x)%y, i//(w*x*y)

[grim abyss]

god

i don't understand 4d either.... what's the extra dimension?

[white vector]

okay, ponder and think about your normal 3d space, right?

[grim abyss]

ok

[white vector]

forget that even exists, purge your mind of it.

it will not help you

space does not exist

[grim abyss]

ok

[white vector]

a point in three dimensions is merely three numbers, the coordinates

just as a point in two dimensions is two numbers

[grim abyss]

yup

[finite jay]

yup

[white vector]

and an index in a 1D array is one number

[grim abyss]

z is depth

[white vector]

depth does not exist

[grim abyss]

lol ok

[white vector]

there is only first coordinate, second coordinate, third, ... nth coordinate

so a point in 4D 'space' is represented by (w, x, y, z)

[grim abyss]

well that's simple enough

[white vector]

lesser minds, who have not yet mastered purging the limitations of 3d space from their mind would like to use t instead of w
so now, my arm is at coordinates 0,0,0, but in 4 minutes it might be over yonder, at (4,3,-2)

but if you can purge your mind of 3d space or enable each point in 3d space... to be a space, not a point, your mind will achieve higher dimensions

(1, 5, 2, 2, 4) is a point in 5D space

simple? yes it is.
easy to visualise? not in 3d space.

[grim abyss]

hmmm

[white vector]

essentially what you want to do is see how translating a problem from a flat plane to space as you know it works, and apply that to space as you know it, treating 3D as 2D

really, the only thing that's actually difficult to visualise is a 4d hyper-solid

a mantra like this helps:
a sheet of paper is to me, as i am to a 'hyper-solid'
a string is to the paper as the paper is to me
again, a sheet of paper is to me, as i am to a 'hyper-solid'

but that's getting off topic

[grim abyss]

yeah you lost me lol

[white vector]

so techincally that's a 3d matrix in 4d space

u know what i'll make a whole 4d atrix

[grim abyss]

?

[white vector]

damn to generate this thing i'd need the going back algorith,m

def get_index(self, *args, **_wxyz):
        if len(args) == 2: wx, yz = args; w, x, y, z = self.wxyzn[:-1] if self is not None else (_wxyz[this] for this in _wxyz); (i, j), (k, l) = get_2d_co(wx, w, x), get_2d_co(yz, y, z)
        else: i,j,k,l = args; w,x,y = self.wxyzn[:3] if self is not None else (_wxyz['w'],_wxyz['x'],_wxyz['y'])
        return i + w*(j + x*k + x*y*l)

the important bit is i + w*(j + x*k + x*y*l)

[grim abyss]

has discord messed up the formatting on that?

[white vector]

nope

unless your browser width is finite...

i do things with as little newlines as possible, usually

[grim abyss]

ahh

[white vector]

just google Horror Vacui to get an idea of how i code

[grim abyss]

so you want to fill all available space ?

it's very hard to read though

[white vector]

w=4;x=5,y=3,z=2
get_num = lambda i,j,k,l: i + w*(j + x*k + x*y*l)
a = [[[[get_num(i,j,k,l) for i in range(w)]for j in range(x)]for k in range(y)]for l in range(z)]
print(a)

use that to generate what I'm talking about lol

[grim abyss]

ok

[white vector]

so the maximum number is 4*5*3*2 if my brain gears are turning correctly...

quick math what's the range of numbers I expect to find in this matrix?

i.e. number of elements

-1

well

not -1 for range input

[grim abyss]

idk lol

[white vector]

120-1 is 119

so range(120) is the range we're working with

[grim abyss]

ok

[white vector]

give a number 120 or higher and you'd get coordinates outside of the matrix

[grim abyss]

yup

[white vector]

so given a number in the range(120) and those 4 constants there used to generate this matrix, what values of i,j,k,l were inputed to get_num during the generation process.
for example, I'll give you everyone's second favourite number 69

[grim abyss]

what's everyone's 1st favorite number?

[white vector]

420

[grim abyss]

hahahahha

[white vector]

weed still gives you a bit more of a high than dopamine

[grim abyss]

and shrooms/lsd go even better

but anyway

[white vector]

so first you look at it, find the coordinates of the number, then remember how your brain did it

[grim abyss]

what was the question? lol

[white vector]

given 69 and a matrix generated by side lengths w=4;x=5,y=3,z=2
where is the number 69 in this matrix?

[grim abyss]

I'm thinking I need to study Linear Algebra and Linear Transformations. This applies to what I am trying to accomplish.

Are there prerequisites for that?

[white vector]

mathematical methods

not exactly requisite, but recommended

it used to be called Math C

it is sometimes called specialist mathematics

it's essentially big-brain operations like what we're doing

also the number line become a number plane and imaginary numbers suddenly exist and are very real despite not being 'real' and can haunt you....

[grim abyss]

yeah my brain hurts and needs a rest haha

[white vector]

so that's essentially what you're getting into if you want to dive into high level math

[grim abyss]

i just want to be able to understand the math behind vectors and such for 2d/3d graphics

[white vector]

if you think that's bad, you end up with normal 2d functions needing 4d space for full representation

[grim abyss]

like a motion detector. like in halo. I saw that implemented in c# and it went over my head because of my inexperience with mathematics...

but for some reason. how that simple motion detector works fascinates me....

[white vector]

vector mathematics, linear algrebra ... CROSS PRODUCTS, DOT PRODUCTS...
veeeeeeeectooooooooorrrrrrsssssss

yeah you want to get your arithmetic right cos there's gonna be a lot of it in store for you down that path

you want official math edumication?

[grim abyss]

If someone would of made it clear to me when I was young, all the incredible stuff you can do with math then I would of paid A LOT more attention. I didn't have any 'gifted' teachers that possessed such skills though.....

[white vector]

Most of schooling wasted the time i was open minded with just simple arithmetic and didn't go down interesting paths like linear algebra until the last two years of HS

[grim abyss]

well i'm damn near 40 so i'm late to the party....

[white vector]

hence I've recently had to cram as much in before i get too old to efficiently learn mathematics...

[grim abyss]

i might be too old

then you hear of the so called "polymaths" and it's like.....wtf.....

[white vector]

if i was 40 and hadn't studied linear algebra yet and was introduced to the concepts i just gave you I'd have a brain tumour already, you're doing pretty good

[grim abyss]

well thanks

[white vector]

alright I have three folders here in my MATHDRIVE usb

do you want uber basic, foundational or methods?

[grim abyss]

how basic is the 'uber basic' ? hahahaha

[white vector]

like how to not rely on your calculator

like long division

[grim abyss]

i need to get on with the vectors and matrices so I can move along...

i'm fine using a calculator

[white vector]

like what school wastes half your childhood on just to keep you out of your parents way while they earn enough income to feed you

[grim abyss]

yup

[white vector]

it's better if you know how to not use the calculator so you understand what the calculator is doing

[grim abyss]

good point

[white vector]

okay foundational math i only have the subject outline not the lecture notes

[grim abyss]

ok cool

No idea. Probably better places to ask this question.

Arcade 2.5.5 is out. Release notes: http://craven-arcade.s3-website-us-east-1.amazonaws.com/release_notes.html

[torpid loom]

What do yall recommend for working with paths? Path lib?

[dawn quiver]

hello! anyone using vips? pyvips? image lib

[humble sequoia]

I’m getting a typeError saying unsupported operand type(s) for -=: ‘pygame.Rect’ and ‘int’

[potent ice]

I'm guessing player_One is a pygame.Rect

[humble sequoia]

Yea it is

That one only works for images?

[potent ice]

See : https://pygame.readthedocs.io/en/latest/rect/rect.html#virtual-attributes

[potent ice]

You can save a lot of time by looking at the official documentation 🙂

[thick wasp]

does anyone have knowlesge of platforms in pygame?

cuz i need help

idk how i shoudl do it

i just need a start into the diresction on hwo to do it

[modest jewel]

Can Kivy have a camera rotate around a point?
I googled around and an article said it could do 3D but IDK if it's to the extent I need

I don't need to make a game per say, just a normal UI like I'd make in PySide, except I need 3D and 3D controls

Ping me if you have an answer please

[frozen knoll]

Platformer in pygame? See http://programarcadegames.com/index.php?&chapter=example_code_platformer

Q

[slim heron]

hey im a pygame (and python) beginner and I do not understand why the program doesnt work (error in line 23)

import pygame
backroundcolor = [0, 255, 0]

# Intalize the pygame
pygame.init()

# create the screen
screen = pygame.display.set_mode((800,600))

# Title and icon
pygame.display.set_caption("Space Invaders")
icon = pygame.image.load("ufo.png")
pygame.display.set_icon(icon)

# Game Loop  
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
# Backroundcolor
    screen.fill(backroundcolor)
    pygame.display.update()

Errormessage:

[dusty vine]

Hello, i'm using pygame, and I was wondering if there is a way to make a sprite move from a point A to a point B, by following a line between these two points ?

[slim heron]

Update: I've removed the backroundcolor line but its still giving me an errormessage cause something seems to be wrong with the last line:

[real peak]

I've never used pygame but it looks like an indentation error

    pygame.display.update()```

are these supposed to be in your for loop?

hmm no doesn't look like it

I'm not sure

[rapid echo]

Hey, I’m learning python from scratch, but I am interested in game development. I am a total noob.

[low shadow]

learn all the basics and then learn object oriented programming in python
after that try game dev

[thick wasp]

thx

[normal silo]

Use linear interpolation (can be used to animate various things).

The function is commonly named lerp. It's highly used in games.

[normal silo]

Example:

import pygame

screen = pygame.display.set_mode((800, 600))

clock = pygame.time.Clock()
FPS = 60

paused = False

start_x = screen.get_width() / 2 - 25
stop_x = start_x + 200
start_y = screen.get_height() / 2 - 25
stop_y = start_y + 200

x = start_x
y = start_y

animation_timer = 0.0
animation_duration = 1.0 # The animation duration in seconds.

# a is the start, b is the stop, t is time (between 0 and 1).
def lerp(a, b, t):
    # You can see that as t goes from 0 to 1,
    # the return value goes from a to b.
    return b * t + (1.0 - t) * a

while True:
    dt = clock.tick(FPS) / 1000.0 # dt is the delta-time in seconds.

    if not paused:
        animation_timer += dt # Add change in time to the timer (timer increases).

    if animation_timer >= animation_duration:
        animation_timer = 0.0 # Reset the animation.

    x = lerp(start_x, stop_x, animation_timer / animation_duration)
    y = lerp(start_y, stop_y, animation_timer / animation_duration)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            quit()
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_SPACE:
                paused = not paused

    screen.fill((0, 0, 0))
    pygame.draw.rect(screen, (255, 0, 0), pygame.Rect(x, y, 50, 50))
    pygame.display.flip()

[normal silo]

Your indentation is incorrect. Make sure you are not mixing spaces and tabs for indentation and that if you are using spaces, the number of spaces are the same on every line that is indented.

[slim heron]

Thanks man it worked ❤️

[dawn quiver]

yeah you should study the basics of python before trying out any libraries

[plucky sonnet]

you should do both, learning only will make it boring, trying only will make it a pile of poop

[dawn quiver]

not if you find programming interesting in the first place

[plucky sonnet]

learning object-oriented programming was a big pain for me to stay awake & I'm a programmer for a living

[bitter hill]

anyone wanna help me?

through dms possibly

i have not the slightest idea of coding, but want to make something cool

[dawn quiver]

Learn python first

[dawn quiver]

Then learn pygame

[bitter hill]

huh

ok

[dawn quiver]

It's for making simple games

[bitter hill]

now how complex can a game get with it?

[dawn quiver]

If u want to make complex games, learn c# or c++

[dawn quiver]

A 3d game is complex

A multiplayer game is complex

[bitter hill]

can i make a game with dialouge, items, and boss battles?

and economy

[dawn quiver]

With python?

[bitter hill]

yes

;-;

[dawn quiver]

Yes , u can .But , pygame is not a game engine but a graphics library .So , u need to make everything from scratch

[spice notch]

I've been doing this for a minute, it's actually not bad to start from scratch on this

[dawn quiver]

If you want to get a job or is serious about game dev, I suggest you to learn a game engine . @bitter hill

[normal silo]

@bitter hill These things are independent of pygame. You can code those systems and have a text only interface if you want.

In fact, I recommend making a text adventure first.

With that you can learn how to make a dialog system, inventory, turn based combat, economy.

Without getting your attention diverted by graphics.

[bitter hill]

can i make cool battles?

not turn based bull?

[normal silo]

Not in text input games, but you can just keep everything else and replace the combat later to something more real-time.

[bitter hill]

ok

what about attack dodging?

like for example

someone uses an op move, you can dodge it sometimes

[normal silo]

Pokemon is a turn based game in which you can dodge.

Use it as an example of what you can do.

[bitter hill]

can i have cool animations during special moves?

[normal silo]

No, but you can again keep everything but slap on some graphics and animations later.

[bitter hill]

this is confusing

[minor forge]

hvae the learn python basics yet lol

[normal silo]

To understand what I mean, take for example pokemon. The code that does the actual combat and the code that visualizes it are separate. Pokemon could be a text adventure game if you removed the graphics / animations.

[bitter hill]

now i can do this stuff in c++, yes?

[normal silo]

Yes you can do anything in c++.

[bitter hill]

oh surely not anything

[normal silo]

No, anything.

[minor forge]

ANYTHING

[bitter hill]

ok

[normal silo]

C++ is fast and can control any part of a computer system.

Learn python first though and make some simple text only games.

[bitter hill]

can i make a program that gnomes anyone with a red beanie on, in c++?

[minor forge]

what

[bitter hill]

oh

[normal silo]

Yes

[bitter hill]

...

noice

[minor forge]

"can i make a program that gnomes anyone with a red beanie on, in c++?"

[bitter hill]

idk

[minor mulch]

Like they said, C++ is able to do literally anything, it’s just a lot more complicated than Python. So learn Python first, then go to c++

Python is almost as diverse, but it’s slow and not made for things like professional games

If you want to make more complicated games, go for C# or C++ and a game engine, not Python and Pygame

[real peak]

I'm not sure that learning Python as a stepping stone to C++ is a good idea at all

If you really plan on going down the gamedev route of C++ or C#/Unity you should probably learn computing fundamentals, some basic scripting (probably not using Python) and then jump straight into the C language of your choice

you don't want to get thinking pythonic

[normal silo]

I don't think the starting language really matters, people used to often start with BASIC in the old days and now they are some of the best game devs out there.

As long as they don't start wasting their time with pythonic craziness in large projects, like focus too much on OOP or the details of how python works.

(C and C++ will force you to learn the ugly details up front before you even get something working (it distracts from the actual programming))

[minor mulch]

If someone doesn’t know much about programming, a simple language like Python is perfect to start them off

[real peak]

Yeah I think I've changed my mind

I do however think the education would be a little different

an early topic is usually string manipulation, and among other topics these are very particularly pythonic

list comprehension, etc.

[minor mulch]

I would say, my best choice for organization to get to c# would be Python for basics of object oriented programming, the JavaScript for syntax practice, then C# with some reading would probably be a good way to start off

[real peak]

JS might be a great starting point in general. Using a browser as a GUI for things as simple as hello world is a huge advantage for a beginner

and it's intuitive to not have to install JS as opposed to Python, which pits beginners against the terminal, pip, venvs, etc

[minor mulch]

Another thing to think about is C# requires the dot net core to run, so you technically would have to know how to install and configure a language via the terminal

[normal silo]

JS would require learning HTML and that seems like a mess for beginners. But at least it's kind of free in structure like python, unlike say Java in which you have to first spew out of bunch of class code and public static void ....

[minor mulch]

Yeah

[minor mulch]

On top of that, Java is a mess to install

[normal silo]

IMO what beginners often lack is the ability to visually parse code (which any c-statement-syntax-like-language like Python will teach), and following control flow / loops. Python will get both of those things across.

[normal silo]

Yeah it's why python is probably so popular, it's a lot like how BASIC used to be, just make a file and go.

[minor mulch]

Mhm

[normal silo]

(or repl)

[minor mulch]

Also, I would say, if you wanted to teach younger kids programming, Lua is perfect

Lua reads like Scratch

[real peak]

you're definitely right, Python might be the way to go, with Lua and Ruby and the like as good backups. I still think a "learn Python" course and a "learn programming with Python" course should look somewhat different hough

[normal silo]

Lua is totally fine too, you need to unlearn the starting at index 1 thing, but that is trivial.

[minor mulch]

Exactly

[normal silo]

I think I get what you mean. Many courses / tutorials online will start rat-holing on various aspects of python.

[minor mulch]

^

[normal silo]

Like you don't need to know the syntax of how to do something 10 different ways.

[real peak]

my uni taught a section on advanced string manipulation between the for and while sections, so I'm a bit jaded there

[normal silo]

Or memorize every built in function and keyword.

It's the type of thing schools do because it's the lazy way to be able to create questions for an exam.

[minor mulch]

Yeah

[normal silo]

(or time constrained as they usually are)

[minor mulch]

I’ve had to help my friends through Python assignments because the teachers just went and drilled a hole through one topic instead of showing the rest of the lesson

[normal silo]

It's my hope that in the future we get a C/C++ replacement that makes getting into coding as simple as python (just make a file and go). There is Rust but IMO Rust is what happens when you go overboard and pack every neat trick you found in other languages into your own. It's too much (modern c++ shares this same issue, Rust probably got it from them).

[fading edge]

the crewlink mod for among us somehow gets data from the game (player position, player status) anyone knows how it does that?

[polar latch]

PYGAMERS need assistance pls : I would like to display a GIF on the main screen, I have made my functions and calls on the main, it works just fine. HOWEVER, FPS being set at 60, the GIF sprites animation pace is way too fast, anyone got a trick?

I need to slow down the FPS just for the GIF, I am thinking : Should I just increase the number of sprites in my GIF, or can apply a FPS dedicated to the GIF (let's say, set at 20)

[polar latch]

I've found the solution actually !

[surreal talon]

I was wondering if someone could help me out. I have a list of lines that Im looping through with a for loop. During this time I need to check if a object has collided with the line. Is this even possible with lines?

[tame nexus]

you can only make console games in python

[austere flax]

Yes its possible to check if an obj has collided with any of the lines from the list

Something like make the list an object and when you go to test the collision just loop thru each one

[light silo]

I need help with a realpython pygame tutorial https://realpython.com/pygame-a-primer/#pygame-concepts

Main loop

while running:
# Look at every event in the queue
for event in pygame.event.get():
# Did the user hit a key?
if event.type == KEYDOWN:
# Was it the Escape key? If so, stop the loop.
if event.key == K_ESCAPE:
running = False

    # Did the user click the window close button? If so, stop the loop.
    elif event.type == QUIT:
        running = False

This quit line doesnt seem to work for me, the screen opens and it's black but only when i press escape or close the window the proper screen appears but it hangs and stops responding, I have to force quit the python application afterwards

[austere flax]

This will get you to exit the while loop

are the if and elif on the correct indentation

[light silo]

ye the indentations are right

[light silo]

so how do i make it quit safely?

also why does my screen turn black when it first opens? i cant seem to solve that part either

[austere flax]

clear the screen?

pygame.quit()

[crisp junco]

What have you written after the while loop?

[austere flax]

sys.exit()

use these after you detect the quit

in the same block

[crisp junco]

# Main loop
import sys
while running:
    # Look at every event in the queue
    for event in pygame.event.get():
        # Did the user hit a key?
        if event.type == KEYDOWN:
            # Was it the Escape key? If so, stop the loop.
            if event.key == K_ESCAPE:
                running = False

        # Did the user click the window close button? If so, stop the loop.
        elif event.type == QUIT:
            running = False
pygame.quit() #De=initialising pygaem
sys.exit() #Quitting the app

[light silo]

I just continued with the rest of the game

Fill the screen with white

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

Create a surface and pass in a tuple containing its length and width

surf = pygame.Surface((50, 50))

Give the surface a color to separate it from the background

surf.fill((0, 0, 0))
rect = surf.get_rect()

This line says "Draw surf onto the screen at the center"

screen.blit(surf, (SCREEN_WIDTH/2, SCREEN_HEIGHT/2))
pygame.display.flip()

[light silo]

oh thanks!

[light silo]

this was my code before making any changes

Import the pygame module

import pygame

Import pygame.locals for easier access to key coordinates

Updated to conform to flake8 and black standards

from pygame.locals import (
K_UP,
K_DOWN,
K_LEFT,
K_RIGHT,
K_ESCAPE,
KEYDOWN,
QUIT,
)

Initialize pygame

pygame.init()

Define constants for the screen width and height

SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600

Create the screen object

The size is determined by the constant SCREEN_WIDTH and SCREEN_HEIGHT

screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))

Variable to keep the main loop running

running = True

Main loop

while running:
# Look at every event in the queue

# Did the user hit a key?
if event.type == KEYDOWN:

if event.key == K_ESCAPE:
running = False

    # Did the user click the window close button? If so, stop the loop.
    elif event.type == QUIT:

[potent ice]

@light silo use https://paste.pythondiscord.com/ for large code sections like that

[light silo]

ah thanks i was wondering how you did that

[deep zenith]

Hejhej, i just wanted to ask if there was anyone who has experience combining python with a game engine like unity? 😁

[potent ice]

Never done that. Seen some guides for it. There is a "Python for Unity"section in the official docs.

[clear cloak]

I made an exe file through PyInstaller and i want to send it through gmail but it wont let me for security reasons... I tried compressing it into zip and rar or even made it a txt file but it still wont let me send it... Is there any way to make it happen?

[polar latch]

Someone already replied to me here for the same issue about a month ago, unfortunately any exe issued by pyinstaller is considered as false positive by antiviruses, there's nothing you can really do I guess

I am sure an expert here will be able to suggest another installer

[clear cloak]

alright thank you <33

[gilded grove]

hey guys what IDE should i use for pygame

i have VSC

[analog barn]

Is using sets here redundant? Try to avoid an errors where two bullets collide with the same alien (the blowup() and remove_self() methods both use Sprite.remove(group)) ```py
def _bullet_alien_collide(self):
"""Collide all the bullet sprites will all the alien sprites, remove the
bullet and then blow up the alien"""
collisions = pg.sprite.groupcollide(self.ship.bullets, self.aliens,
False, False)
# unpack the aliens from the collision dict and add them to a set
# {<Bullet Sprite(in 1 groups)>: [<Alien Sprite(in 1 groups)>]}
hit_aliens = set(
alien for alien_list in collisions.values() for alien in alien_list
)
for alien in hit_aliens:
alien.blow_up()
for bullet in collisions.keys():
bullet.remove_self()

[analog barn]

pycharm is amazing, it makes renaming variables and functions so easy

but it's a memory hog

[elfin kernel]

hey guys i need some help with the moevement of my main character

how do you guys type with that font??

[analog barn]

These are backticks, not quotes. Check this out if you can't find the backtick key.

[elfin kernel]

i need to make diagonal movement for my character

can anyone help me pls

[gilded grove]

Eh I’ll do VSC

[clear cloak]

alright will do thanks

[analog barn]

Do you have an x and y velocity for your character?

[gilded grove]

how do you guys organize your file structure for pygame?

bc in web dev they encourage you to do it a certain way

[elfin kernel]

i posted the part of the code that is for movement in #help-cherries

[potent ice]

That's more like a general python project question. I would at the very least split things into modules/script when possible.

Have a directory for your project containing a all the python files and a resources directory for images, sound and whatnot.

If needed make some modules into directories

[elfin kernel]

so i till need help

[gilded grove]

I had the same issue when I started using Visual Studio Code with Python. It has nothing to do with having another pygame.py or not installing it properly. It has to do with the fact that Visual Studio Code takes your code literally, and since you cannot import pygame.init(), it thinks that it isn't a correct module.

so i have this issue

it says this in stack overflow

To fix this, open up settings.json (go into your settings, and click the {} icon) and paste

but when i go into settings i don't see a {}

i have no settings.json

[potent ice]

What problem is it exactly?

[gilded grove]

pygame gets underlined with red
