for a game jam

:D

i got all the art and sprites i wanted

now i need to start programming it tmrw

[torn patrol]

👍 first texture after 3 hours loaded

@tranquil girder thanks for the help ! 🙂

[clear glacier]

i still can't it

need help 😦

[torn patrol]

i am using ursina

but still wait

[clear glacier]

i wanna use ursina

but i can't

i downloaded but it's not working

[torn patrol]

https://stackoverflow.com/questions/3580500/active-texturing-with-pygame-possible-what-concepts-to-look-into

check it out

[clear glacier]

ok i'll

[torn patrol]

yup just a scroll a little down there

the guy laoded that texture

[round obsidian]

@clear glacier If you're using PyGame, and you named your file pygame, then your file thinks it's trying to import from itself.

[clear glacier]

ahhhh smh

lmao

my bad

[round obsidian]

A common mistake :D

[clear glacier]

no one has figured it out yet

except you

😄

ty

[clear glacier]

i wanna ask smthng

how can i use textures?

@round obsidianbtw, why that game isn't closing ??

i can't close it

[round obsidian]

as far as I can tell you haven't made a provision for intercepting any of the window-close events. I don't use PyGame so I'm not sure, but that may be the reason

[clear glacier]

ahh but i'm clicking the close button but it isn't working

[tranquil girder]

make sure your script is in a folder you created for your project as it will search for the texture from that folder. so if you put it directly on the c disk for example, it will search every file on your computer. This is covered in the documentation

[torn patrol]

yup

and how many models are there in built there in ursina ?

[tranquil girder]

these: https://www.ursinaengine.org/cheat_sheet.html#models

There's also quite a few procedural models you can use as well

[torn patrol]

can we make endless terrain in ursina ?

Does anyone knows how to make a timer in pygame without lagging the main loop

[frozen knoll]

Going a bit nuts the the glowy things.

[last moon]

that's looks sick! how'd you manage the particle bursts?

[frozen knoll]

Arcade 2.6 is supporting shaders made in Shadertoy format. So I watched a YouTube tutorial and adapted it to this: https://github.com/pythonarcade/asteroids/blob/main/source/explosion.glsl

Pretty cool what you can do in a glsl shader without too much code. Kind of complex though.

Hello guys i want to start programing with ursina can anybody help me or send a free course or something?

[white vector]

For those interested in console development, this class will abstract away colouring. Note: the fourth parameter switches highlight instead of font color.

@lambda c:c()
class rgb:
  def __str__(self):
    return'\x1b[' 
  def __format__(self, a): 
    rgb = a.replace(',',';').split(';') 
    r,g,b,H = rgb + [0]*(len(rgb)==3) 
    return f'\x1b[{38+10*bool(H)};2;{r};{g};{b}m' 
  def __call__(self, r, g, b, end=False): 
    return lambda s,end=end:f'{self:{r};{g};{b}}{s}'+end*'\x1b[0m' 

There's also printable directions, to move the cursor, using ^[[ ( ^[ is typed with ctrl-[ or coded as chr(27) )
A B C D is up down right left respectively
s pushes position to memory, and u recalls it.
That and curses or msvcrt should be all you need to develop some pretty cool console games.
I've done minesweeper already, I'm doing Tetris and 2048 next

Warning: if you play around with raw escape sequences too much, you might experience unexpected behavior.
For example, a partial sequence will 'swallow' the next character, the length of a sequenced string is longer than it's display length hence left, center or right alignment using format strings will under compensate

[tough flicker]

hellooo can someone give me some type of beginner guide to creating a game using python (since thats the only language ik as of now)

[main cove]

@tough flicker python crash course

[tough flicker]

Like the book?

[main cove]

Yes

There is a dedicated section of the book which looks at creating a game with pygame.

[tough flicker]

tysm !

[manic lotus]

hey, as someone who has had experience in both python and unity, is godot a good choice to make a game with since its a mix of those things?

[frozen knoll]

@tough flicker Try https://learn.arcade.academy

[tough flicker]

thanks!!

[last moon]

From the little bit of godot that I learnt helped people with it, I think unity gives you a lot more control over your game than godot provides. Not to say you can't write your own scripts/use prewritten ones but it's easier with unity. That being said, if your projects are on the simpler side logically, imo godot would be easier.
Not to mention the textures in the unity asset store are a lot better than ones on itch.io/etc

(also unity has a python api)

[faint berry]

the link you sent is not opening

[heavy plank]

i fixed it

thanks for replying

[faint berry]

in your init method or just set these once time.

timer_name = pygame.USEREVENT + 0  # (increase this number by timer count.) 
pygame.time.set_timer(timer_name, 100)  # each 100 ms, trigger.

in your update method or just in while statement

for event in pygame.event.get()
    if event.type == timer_name:
        print('it works! just bla bla...')

[golden gazelle]

could u send me the code for this if not is it easy to make?

[frozen knoll]

The GitHub is linked in my post.

[still anvil]

k but is it easy to make and how long did it take for u to make?

[faint berry]

I made an pygame timer based animation example code for this 2 day before, just look my profile and go to my github, it is in there.

[proven fractal]

Thanks

[dawn quiver]

We use a defined fps to control animation

so lets say we dont define it, and let the game run at the highest speed the users machine allows

then how would we make sure that user A's character wont run slower than user B's character

[dawn quiver]

Nvm

i figuered it out

you need to use delta time

[faint berry]

yeah

[left geyser]

guys so I just started to learn game development in pygame and I was wondering

do you think it's a good place to start or should I do something else first?

[round obsidian]

@left geyser it's a fine place to start, you can always move on to bigger things

If you know nothing about programming, you can cut your teeth on the workflow with Python and learn the basics of game design

I'm writing games in Python right now, and for what I'm doing (which is not huge) it's more than adequate

[subtle bridge]

well guys i finally created a tic tac toe bot

im out

[mental mortar]

Some

one teach me

how to create a

game in phython

[runic nebula]

you can use pygame library

it is easy to learn and you can develop fastly some small games

but pls don't expect the features of a game engine

I highly recommend you to watch a tutorial video and than start coding. When you encounter some issues you can check documentation of pygame

[mental mortar]

ok

[frozen knoll]

If you are wanting to learn to program, and do game development, maybe check out https://learn.arcade.academy

That covers the Arcade library. Or http://programarcadegames.com covers pygame. @left geyser @mental mortar

[dawn quiver]

[rough zodiac]

does anyone have experience with steamworksPy as the documentation given on how to install it says to copy over the "steamworks.py" file, even though there's not a single file with that name in the repository

[tranquil girder]

where does it say that? looks like a normal python module you can install with pip
just give pip the link to the .zip file or the git repo if you have git

[rough zodiac]

"Copy the steamworks.py file and the newly compiled SteamworksPy.dll or SteamworksPy.so or SteamworksPy.dylib file to your project folder."
https://philippj.github.io/SteamworksPy/

[tranquil girder]

looks the documentation's not been updated

https://github.com/philippj/SteamworksPy/commit/819d5cc0fb5e77090a11b998a3ba220139fcbdab

[rough zodiac]

yay~

[tranquil girder]

I think you can just copy the module

[rough zodiac]

i can try?

[tranquil girder]

the folder called steamworks

[rough zodiac]

that seems to have done the trick

Thank you so much!

[hard field]

How do you make games for android with python?

[sweet condor]

[lean cosmos]

Opinions?

[royal hawk]

pygame question: should i manually calculate mouse position when there isnt much buttons on screen or would i really like a pygame_widgets.Button() even when there isnt a lot of buttons?

[white vector]

You could also make the game in a console using curses (Linux) or msvcrt (Windows) for keyboard presses, and f'{chr(27)}[38;2;{r};{g};{b}m' to make text coloured, etc.

but GUIs are probably more intuitive

I'm doing tetris next, but unlike minesweeper, the algorithm hasn't come to me in my sleep...

I'm going for the standard approach of a grid with blocks with ids.
I'm thinking each tetronimo be separate blocks but coordinate relative multi-directional displacement in order for a block to rotate, plus keep a reference to fellow blocks in a tetronimo so it keeps its shape at the edge.
This might be challenging.

[patent rune]

Tetris would be a fun project for python

    shipy = 640
    vel_ship = 40
    bulletw = 5
    bulleth = 10
    bulletc = (100,100,150)

    bulletf = False


    screen = pygame.display.set_mode((600,680),0,0)
    pygame.display.set_caption('Alien Invation')
    myship = pygame.image.load('spaceship1.png')
    myship = pygame.transform.scale(myship , (40,40))
    ship = myship.get_rect()
    pygame.draw.rect(screen , (bulletc),(bulletx,bullety,bulletw,bulleth))
    
    


    while a:
        screen.fill(bg_color)
        screen.blit(myship , (shipx,shipy))

        for event in pygame.event.get():
            if event.type == QUIT:
                a = False
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_a and shipx >= 40:
                    shipx -= vel_ship
                if event.key == pygame.K_d and shipx <= 500:
                    shipx += vel_ship
            


                    

        
        pygame.display.update()
game() ```

why is my bullet not getting on the screen

[dawn quiver]

Looking good, keep going!

[solid meteor]

It looks like you're filling in the background after you draw the bullet to the screen (meaning it covers the bullet).

[mental mortar]

Yo

[faint berry]

Draw your bullet in your game loop(while statement) because you draw it once, and just after you are refreshing your screen and it disappears.

[sage rain]

very cool

[tranquil girder]

tell us what you did, what you expect to happen and what happens/doesn't happen

[faint berry]

if you want to use python in your game development, use pygame, arcade, turtle etc, if not, use Unity and other engines

[white vector]

what about the straight console?

hang on let's say i've made some beautiful image in PIL (pillow), how do I display it?

[proper peak]

like, on the screen? you'd need some graphics library (or a game library)

or if you just want to show it in the system's image viewer, .show() does that

[white vector]

would.show() work with multiple rapid requests?

or does it make a new instance of system's image viewer each time?

[proper peak]

I mean, if multiple image viewer windows opening is the intended result

[white vector]

the intended result is update an already open window displaying an image, rather than create a new process

[proper peak]

Are you already using any graphics/GUI/game library?

[white vector]

nope. although i have kivy at the ready

what im using now is the console, using escape sequences for low level graphics, and msvcrt for stream override

but i was thinking get higher res with PIL and something that can show image data

like in matlab you can just Image(arr);

[proper peak]

Show how, though? In a window? Then you need something that can open a window - a graphics library at least

pyglet, say, or start using the kivy as you're planning

[white vector]

so how do you show an image in those?

and which one's faster at it?

[proper peak]

Pyglet is lower-level, it's essentially a wrapper around opengl and the like. There, you'd create an image object:
https://pyglet.readthedocs.io/en/latest/modules/image/index.html
from the PIL image (using .tobytes() and creating a new ImageData from them)
and .blit() it on the window.

in kivy, google tells me there's simply an Image widget for showing images.

[white vector]

interesting

I'd ask in their server but i'm banned :/

My code is too atrocious XD

[lament condor]

what does blit mean if anything

i remember seeing it in pygame and was like "this is a weird name"

nvm

[proper peak]

[...] which stands for bit block transfer
apparently.

[last moon]

There’s also moderngl which is essentially just a opengl wrapper

[white vector]

oh?

!pypi moderngl

[frank field]

moderngl v5.6.4

ModernGL: High performance rendering for Python 3

[white vector]

so this uses the gpu to make rendering go brrrrr?

[last moon]

you can't render without the gpu (in modern systems)

but that'd probably be the lowest you could get without using c[++]/etc

[last moon]

that being said, you can do calculations on the gpu (floating point + parallel calculations especially) through shaders/dtivers/idrk I still haven't gotten a straight answer about that

[lament condor]

lol i wonder why people use python for this kind of optimization

might as well use C right

[potent ice]

@lament condor moderngl is written in C/C++ so you are kind or already doing that

[lament condor]

that's what i meant, might as well just use C all the way

[potent ice]

Why?

[lament condor]

to really optimize it you probably need to know C anyway

cause this just seems counterproductive

to me at least

[potent ice]

Why is it counterproductive?

[lament condor]

when you need this much optimization why use python

imo

it's just for really basic games/quickly prototyping games right

neither of which need much optimizing

but for like actual marketable games

[potent ice]

What kind of optimization are we talking about here?

[lament condor]

graphics of course

i just don't see the use case

[normal silo]

It's for convenience, not speed. The speed is just small bonus because python function calls have large overhead.

Nobody wants to type all the OpenGL goop every time.

[potent ice]

I just don't understand what the image has to do with your case 😄

moderngl is basically a pythonic pyopengl for 3.3 core+ that exposes resources as objects

Something that would take hundreds of lines in pyopengl would be maybe 20 in moderngl

[lament condor]

oh makes sense

[potent ice]

Try setting up shaders, vertex arrays and whatnot. That is crazy amount of work

It also makes OpenGL easier because it tries to hide most of the pitfalls in opengl

[normal silo]

(and if you do, you will probably put that stuff into functions / objects that end up being a copy of moderngl more or less)

[potent ice]

yeah and there are so many errors you can make it's rediculus

[normal silo]

Yeah OpenGL is a terrible API (got better over time, but still really easy to break stuff and hard to debug).

[potent ice]

3.3 core+ made it better at the very least (for me personally)

[normal silo]

But you have to use it if you want anything remotely cross platform and don't want to write 10k LOC for a triangle in Vulkan.

[potent ice]

Yeah that seems to be the case. There are projects emerging to fix that, but not quite there yet

[normal silo]

(Such as the implementation of OpenGL in Vulkan (but you can actually debug it))

[potent ice]

Experimental vulkan version of moderngl : https://github.com/glnext/glnext

The plan was that moderngl should switch to vulkan, but that was too hard to make backwards compatible so this was created instead

[normal silo]

i see

[potent ice]

Then this was created recently as well : https://github.com/moderngl/moderngl.js

webgl is even more weird at times

[dawn quiver]

No problem

[normal silo]

OpenGL might be bad, but nothing is worse than introducing yet another "standard" cough vulkan, webGPU cough

(or yet another shader language that's really just the same thing as glsl with arbitrary differences)

(it's like devolved since C, the entire point of which was to write once and ship on multiple different platforms)

(just add the missing stuff and call it OpenGL 5.0)

Hi, I would like some help with Pygame - python, with displaying a button. If you are familiar with Pygame, please let me know!! Thank you

[hearty briar]

I want to ask, is paython suitable for game development, and what application or game engine is suitable for python?

[proper peak]

For learning game development? Sure. For developing serious games? Not much. As for game engines - if you mean those you can use in a Python program, there's pygame, arcade, and 3d engines like panda3d. If you mean a standalone game engine like Unity that can be scripted in Python - Godot can be (though not officially).

[digital maple]

can someone send a code for a working pong game in python/pycharm pls? i need it badly.

P.S. pls put hashtag and what the code part is used for\

[dawn quiver]

You can very much do indie game dev with Python

[dawn quiver]

That wont help you

[dawn quiver]

Neither will this

If this for school/assignment/showoff/learning this isnt going to help you 🙂

If you really want to try and understand whats going on, you need to implement it yourself

first off
Its fine to use a tutorial to understand the concepts
If i stretch it, its even fine to understand the basics
But this is not something you should copy from a tutorial
Trust me
i have tried, and it ruined all of my games after that
because i had to copy that collision code
for which i had to copy that class
for which i had to copy the entire platformer
You dont understand, how frustrating it can get
I stopped for a while, when i came back, i tried to do things by myself

In this case its not a tutorial, its a code snippet

And you definetly cant learn by just getting a whole chunk and trying to understand it

---

Say, do you think any two people think the same way?
If i were to ask you to solve a simple math problem, you may arrive at the same solution but how you calculated it, both mentally and written would be different
Code is the visual form of our calculations
The solution is what we get when we run the code
You cant try to imitate someone elses code, because thats trying to imitate someone elses calculations, which is trying to imitate how someone else thinks
To conclude,

Do it yourself, and if you get errors, come here for guidance, we dont just give you the whole code

[digital maple]

ok

actually it wasnt an assignment

it was to show off to my friend this community and make him start python

learning it

just to loosen him upand saying that the community helps people and doesnt just make fun of people who cant learn

[digital maple]

It is seriously not an assignment

And I already tried making it with pygame but the speed of the ball was way too fast

[midnight heart]

how can i remove the white background in a sprite?

[solid meteor]

Erase the white part from the sprite, making it transparent instead.

[midnight heart]

yes, how can i do it?

sorry i forgot to tell you. i'm using pygame

[left geyser]

I'm trying to replicate the game flappy bunny in python and I can't do it

I'm stuck on the part where you actually make a character move through an environment

idk how to go about doing that I was originally thinking just making the obstacles move toward the player and the player goes through the obstacles but i think it'd look kinda weird if I did that

https://www.youtube.com/watch?v=CcI2xbmyHp8

This is the game guys any ideas?

[exotic laurel]

I believe that's the way flappy bird is actually built, you limit the player movement into a single axis, up and down, and then you move the pipelines through the screen - demolishing the ones out of frame and remaking a new obstacle and so on

[midnight heart]

please help me

[exotic laurel]

Is it pygame?

[midnight heart]

yes

[exotic laurel]

Is the original picture transparent?

[midnight heart]

no this isn't a picture

it is a rectangle

[exotic laurel]

Oh okay, then you can remove the rect color completely

[midnight heart]

i mean it is a sprite with a rectangle and a text

[exotic laurel]

I thought you wanted to remove the whites of a picture

[midnight heart]

yes

[exotic laurel]

And that sprite's model comes from a picture correct?

[midnight heart]

i want to remove it

[exotic laurel]

Question, is it a picture or a rect you made with pygame - because its getting unclear

[midnight heart]

it is: ```py
class button(pygame.sprite.Sprite):
def init(self, pos, size):
self.image = pygame.Surface(size)
self.rect = self.image.get_rect()
self.rect.topleft = pos

and in the image is blit a rectangle and the text

[exotic laurel]

Great, you can use the set_colorkey then

I am not sure if it is convert_alpha or convert though so you'll have to see

[midnight heart]

to self.image?

[exotic laurel]

This is an example

image = image.convert_alpha() # or .convert()
image.set_colorkey((255,255,255)) # this is the rgb for white ```

Yeah

Make sure to convert it and establish an alpha channel

[midnight heart]

ok thank you

[exotic laurel]

youre welcome

[midnight heart]

it work 👍 🙂

[exotic laurel]

great

[left geyser]

really? but it looks like the environment is moving in the video above

or I might be hallucinating or sumn idk

[exotic laurel]

Yeah it's the environment moving, that's what i said xD

The bird moves in a single axis, up and down only

[left geyser]

Yh but by the environment you just mean the pipe lines right?

I meant the clouds and the trees and stuff

how would those move?

[exotic laurel]

The background too

[left geyser]

oh howd you make the background move?

[exotic laurel]

They can be separated vector images but the idea here is that you have a background big enough and stitchable that you can reiterate through it over an infinite amount of time. So in a general loop there are two background imgaes that loops through tighetly together, you could probably guess what it does from then, if an image is completely out of frame, it gets moved back

[left geyser]

oh lord

is there a video or something about this?

[exotic laurel]

yeah i love this one, here

https://youtu.be/8ppKSy8aUZc

[left geyser]

Thank you so much @exotic laurel

[exotic laurel]

you're welcome

[warm portal]

To remove it use an image editor like photoshop or GIMP

[midnight heart]

thank you i resolved

Random glider attacks? 🙂

[round obsidian]

Random glider attacks! In future builds :D

[analog barn]

I am trying to find a good way to track mouse velocity as a vector so that I can click an object has have it continue moving at the same velocity as my mouse when I let it go. Pretty much, I want to be able to "throw" an object.

    def _update_mouse_vel(self, dt):
        # mouse_hist is a list of vectors representing the last 5 mouse positions
        # the distances (as vectors) between the last 5 positions are added together in order to be averaged.
        # this total_distance_vector is averaged by dividing by the number of distances that were added to it.
        if len(self.mouse_hist) == 5:  # wait until 5 positions are recorded before getting the average
            total_distance_vector = pg.Vector2()
            num_dists = 0
            v2 = self.mouse_hist.pop()  # get last position vector from history
            while self.mouse_hist:  # continue until hist is empty
                v1 = self.mouse_hist.pop()  # get the position that was before v2
                # subtract last position from the one before it to get a vector pointing from v1 to v2
                # and add this vector to the total distance vector
                dist = v2 - v1  # v1 + dist = v2
                total_distance_vector += dist
                v2 = v1  # set the end-point vector to the start-point vector before getting the next starting point
        
            self.mouse_vel = total_distance_vector / (dt * num_dists)  # velocity = average distance / delta time

[potent ice]

That seems to add 1 to bottom once as the space key is pressed. Is that what you are trying to do?

[left geyser]

si

but it doesn't do that

[potent ice]

Add a print to see what is happening

Would't that just move the character one pixel? There must be some other code controlling the movement?

[proper peak]

I'm not totally sure what you're doing here, but isn't it just

(self.mouse_hist[-1]-self.mouse_hist[0])/(dt*(len(self.mouse_hist)-1))

?

because (b-a) + (c-b) + (d-c) + ... + (z-y) is just z-a

[analog barn]

You know I did think about that, but I figured that if I added them all together then averaged all of them it will give me a more accurate vector, but I just did some sketching and I think you might be right, I'm going to compare my current code the your simpler version and see if they give the same results. I'll just run them together and compare the outputs

Ur a lifesaver bro good work ```txt
TEST [71.4286, -250]
LIVE [71.4286, -250]

Learning how to use vectors haha

[proper peak]

oh, and by the way, if self.mouse_hist should probably be a collections.deque with maxlen if it isn't already

[analog barn]

I was using a deque, but I would still have to check if the len(deque) == deque.maxlen right? So I changed it to a list for simplicity

Oh i see what you mean

I can get the average velocity every frame if I don't check for length == 5

ok ok

Wow talk about simplification, thanks again! ```py
def _update_mouse_vel(self, dt):
self.mouse_vel = (self.mouse_hist[-1] - self.mouse_hist[0]) / (dt * self.mouse_hist.maxlen-1)

[proper peak]

This underestimates velocity when the queue isn't full, mind. Which may be what you want, though.

The reason a deque with a fixed length is more convenient is just that you don't have to remove the elements from it manually - you just append a new element each time, and that'll remove the oldest one

[analog barn]

Yeah I changed it to a deque. Yes it seems the velocity is underestimated when the program starts or if the mouse comes from off screen. This is ok though because with a high enough frame rate, deque quickly fills up with fresh values.

[analog barn]

It looks like all of the numbers are blitted to the display one after the other all on top of each other. Maybe try blitting one, waiting, then filling the display with white, then blitting the next, waiting, and so on.

[teal ember]

how are you doing the bullet and player collisions ?

It's naive. There's not enough objects to bother with spatial partitioning

[wheat belfry]

hey guys i have a question

im making a basic aimlabs copy game for a school project and im stuck on how to change mouse sensitivity in game
could someone guide me or help me?

can you ping me if you answer my question cuz ill go rn

[tranquil girder]

depends what engine you're using

[wheat belfry]

im using pygame

i forgot to mention that sry

[wheat belfry]

anyone?

im here rn for 5 mins

[exotic laurel]

No, i believe you are blitting all the text objects into a singular rectangle position, of (sh // 2, sw // 2), doing that makes the objects override each other, so you must change the values a bit so that they don't get jumbled

What is the intent here? Do you want to display numbers just as they are in a row in a line?

Right, and what is the problem?

Ah, that's because you're always looping through the entire list every single frame

Rather than that, you can make an index variable and add onto that, then display it in the next frame, as an example;

index = 0
numbers = [1, 2, 3]

while True:
[...]
  # picking just a single number for the frame
  text = font.render(numbers[index], True, BLACK, WHITE)
  textRect = text.get_rect()
  textRect.center = (sh // 2, sw // 2) 
  display.blit(text, textRect) # displays it

  if index >= len(numbers): # make sure you aren't out of index
    index = 0
  else: # just increase the index
    index += 1
[...]```

The example above keeps an index value of the number and increases it by one after every frame, and the effect is that it loops through the numbers list and displays each and every one per frame

Which is achieved by just showing one single number of that index, per frame

(also I think the frames may be too fast for a human to be even able to conceive the numbers - you can play around with the index to slow it down)

@dawn quiver any questions?

You need a variable to keep track of which number to display at a given frame, in this case i named it index yep

Did you refresh the screen at the end of the loop?

lemme see

Ah, my network is struggling to even load the video, can you copy and paste it here?

Can you copy and paste the code here?

my bad, I just scrolled up

import pygame

pygame.display.set_caption("Number Memory Game")
font = pygame.font.Font('freesansbold.ttf', 64)

numbers = [20, 100 , 500]
index = 0
while True:
    display.fill(WHITE)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()



    text = font.render(str(numbers[index]), True, BLACK, WHITE)
    textRect = text.get_rect()
    textRect.center = (sh // 2, sw // 2)
    display.blit(text, textRect)

    #answer = prompt("Write the numbers you saw one after the other:")
    #for num, input in zip(numbers, list(answer)):
    #    if num == input:
    #        continue
    #    else:
    #        quit()
    #numbers.append(randint(1, 9))

    index += 1
    if index >= len(numbers):
        index = 0
    pygame.display.flip()```

I commented out the pyautogui part because I don't have that.

Yeah, perhaps you have a few mistakes - check.

[round obsidian]

Collisions with the underlying grid are easy enough to detect. I tested it with hundreds of enemies and there's only the most marginal increase in CPU time. I instrumented the app to tell how much time the game loop was taking up and it's TINY.

[teal ember]

o cool

[exotic laurel]

hmm?

[teal ember]

spatial partitioning comes more handy when the naive implementation is n^2

[round obsidian]

getting live stats from the app is the best way to tell how much things actually cost.

[teal ember]

was doing a simulation and had to detect collisions for like 100 circles, quad trees helped a lot

[round obsidian]

yeah, this is all AABB with coarse/fine detection, so it's easy

[ivory patrol]

I'm new to this discord channel

i'm learning Python because it's so popular nowdays

i don't think Python is good for game developing

because it's too slow

Python is a powerful language but it's too slow

[round obsidian]

@teal ember it takes 0.03% of 1/60s to do the game logic and draw loop. When I raised it to 200 enemies it went up to ... 0.06%. And 200 enemies makes the game all but unplayable so that wasn't even realistic anyway

@ivory patrol "too slow" by what standard? I'm developing games in Python right now and getting good results

[ivory patrol]

i think C# is better for game developing

its faster

[round obsidian]

C# definitely has more of the support for the bigger game frameworks

if you want to go make games in C#, nobody's stopping you

[ivory patrol]

I'm learning both C# and Python

[round obsidian]

but some of us are using Python to make games and getting very good results with it

it also depends on what kinds of games you want to make; you wont' be making AAA FPS shooters in Python, for sure

[ivory patrol]

OK👍

[ivory patrol]

Nice😋

[teal ember]

oh thats really cool

[round obsidian]

I've found a bunch of techniques that help speed things up

[ivory patrol]

I've already started learning Python

[round obsidian]

the single biggest speedup was using Cython for the Life grid, and there may be other things that benefit from being Cythonized, but the vast majority of the game logic is Python

I also found that the scheduling of events, and setting the timer resolution for the application (in Windows) really help

[ivory patrol]

can you send the link of the game ?

i want to play it

[round obsidian]

I don't have a playable version for others yet, but I'm getting very close

like, a couple of days, I should have something

by default, the event timer in a Windows application is very coarse. If you want to set it to something that will support a 60fps game, you need to do so manually with ctypes

import ctypes
ctypes.windll.winmm.timeBeginPeriod(2)

(do this before starting the game's event loop)
and when done, on program exit:

ctypes.windll.winmm.timeEndPeriod()

[ivory patrol]

after you made a playable version send it

OK?

[round obsidian]

you bet, I'll be posting a link to it here

there's a playable version that's a much earlier build, though

https://xtaloid.itch.io/xtaloid

but this new version is a total rewrite

[ivory patrol]

Good luck

Are you making this game with a game engine ?

[minor sequoia]

        self.mouse_vel.update((self.mouse_hist[-1] - self.mouse_hist[0]) / (dt * (self.mouse_hist.maxlen - 1)))

[analog barn]

how did you make dat?

This is gonna be bigger than call of duty. I call it BALLS IN SPAACE

[proper peak]

does it have gravity?

[tranquil girder]

I just reparent the selected objects to the gizmo, which are Draggable and unparent them after. Taking local rotation into consideration was a bit more complicated, but I used some entities to help me lock the gizmo to the axis. There's an older version here: https://github.com/pokepetter/ursina/blob/master/ursina/editor/level_editor.py

[analog barn]

Gravity is next

each ball has a mass, just have to write a method to get the force vector to every other ball

[proper peak]

highly suggest to do it in numpy

[analog barn]

That would be a good learning experience for me

Ok I will learn some numPy

This is amazing! are the automata generated as the player moves around, or are they all generated together. Is the map size unlimited? I would love to see your Github repo if you have one

Don't have code to show yet but I will at some point. The automata and player are all genrated together and the map is toroidal

[analog barn]

This is an interesting problem, I've never done something like that, but I do notice that the arrow travels on a parabolic path, and the shaft of the arrow looks like it is a match to the slope of the parabola. Could you model the movement with a parabola and then get the slope of it?

Vector which is the delta position, get the angle of that vector via atan2

^^ Cool idea! Will work with the gravity sim because there is no need to base it off a parabola. The slope of the arrow is computed in real time @spare jackal ```py

[dawn quiver]

Hello guys, I have a weird bug in my program, my function **play_music ** is executed but it ignores some instructions. It prints what I want in the terminal but it doesn't play a music. I have no error message, it just totally ignores the play music instructions.

import pygame
import os
import json

file = open('/home/pi/Documents/Irma/tags.json', 'r')
dictio = json.load(file)
i = 0
soundPath = "/home/pi/Documents/Irma/"
theme = ["epic", "chill"]
pygame.mixer.init()


def play_music():
    theme_path = soundPath + theme[0] + "/"
    list_of_songs = os.listdir(theme_path)
    song = theme_path + list_of_songs[i]
    pygame.mixer.music.load(song)
    pygame.mixer.music.play()
    print("play")

while pygame.mixer.music.get_busy() == True:
    c = input()
    if c == "t":
        break
    elif c == "n":
        i += 1
        play_music()

if __name__ == "__main__":
    play_music()

Do you have any idea of why the music instructions are not executed?

[round obsidian]

print("play")** why do you have two asterisks after play?

[dawn quiver]

I put the function in bold in discord, the asterisks are not supposed to show up...

I'll change that

[round obsidian]

so what does happen when you run it?

[dawn quiver]

It prints "play" in the terminal and then the program ends, it doesn't do anything else.

[round obsidian]

while pygame.mixer.music.get_busy() == True:

it looks like this might not be having the effect you want

what's the intention of that while block?

[round obsidian]

thanks!

[dawn quiver]

The get_busy() method runs code while a music is playing. This lets me skip to the next music in the list (list_of_songs) while the current music is playing.

[round obsidian]

here's the problem. What happens as soon as get_busy returns False?

and if there's nothing playing when you launch the program, doesn't that return False by default? therefore, that loop never runs.

[dawn quiver]

I didn't check that, indeed you might get a point, I'm going to do some test and see what happens. Thanks for the help already.

[normal silo]

The while loop is executed before play_music. Python files execute top down.

(it's not busy at that time and continues on, calls play_music and quits immediately after)

[dawn quiver]

I think I understand the issue, but I'm not sure what to do exactly to solve this. Should I tell the program to run play_music() if get_busy() is false? I tried that but I got the same result. The only thing I want to is to be able to play a music, the get_busy() method is optional.

[midnight heart]

thank you

[normal silo]

play music then wait in a loop for the music to complete

what's the best way to save data with python

like game save data

only example i have off the top of my head is terraria which (not made in python obviously) has special .world and .player save files

and i saw a video a while back about how they're just binary formats

should i just use something like that?

[round obsidian]

One easy way to do it is to take your game state object, typically a class, and pickle it.

[lament condor]

alright that's great cause i'm already trying to do that and that rly simplifies things for me

and i hate to ask but do you mind checking out #help-orange

there's just a bit im confused about

[raw canyon]

But until they are fixed, you dont want to keep them in the same file right?
You could keep them to another .py and import it so that your main file would be short but still you can use that functions once fixed

[steel pecan]

hey how do i make pygame window stay until i close it myself. currently it just closes itself after a split second

    (width, height, colours) = nparray.shape

    pygame.display.set_caption("Image")
    screen = pygame.display.set_mode((width, height))
    screen.fill((225, 225, 225))
    screen.blit(surf, (0, 0))

[mental relic]

Nice! Is it open source?

Also I have kind of a niche question. I’m looking to make a game involving programming in pygame. What would be the best way to display code on the screen with syntax formatting? I was thinking maybe LaTeX but I haven’t found a LaTeX python library that supports code, only math.

[mint zenith]

Look into the pygments library. It can export to many different formats.

SVG might be a good format to use if you have a way of rendering SVG

[teal ember]

pygame doesnt afaik

[mint zenith]

A bitmap image would be the path of least resistance, but those don't scale and they aren't interactive (e.g. cannot select text) if you care about that stuff

[dawn quiver]

isnt python considered too slow for gaming?

[mint zenith]

Depends on the type of game

[mental relic]

@mint zenith I don’t. I just need a fast way to display syntax highlighted code that would change a lot. (The user would buy upgrades to the code but not edit the code directly)

But thanks. This seems like what I needed

[round obsidian]

depends on the game. For AAA games like Battlefield, nobody's writing that in Python. For 2D or 2 1/2 D platformers, shmups, bullet hell type games, Python can be fine

[dawn quiver]

i see

[round obsidian]

@dawn quiver this is a game I'm working on now in Python. Some of it is sped up with Cython, which compiles to C, so Python's speed is not always a limit https://cdn.discordapp.com/attachments/660625198390837248/871498915101438062/2021-08-01_17-03-00.mp4

[dawn quiver]

if you can use cython to compile into c cant you make bigger games as well?

[round obsidian]

sure, if you have the time and energy. But game libraries like Unity and Unreal are generally used for such things, because they have the lion's share of development effort behind them

[exotic laurel]

Thanks! yep it's at https://github.com/Rickaym/PyAscii/ , been working on it on my own, but if interested in collabs just hmu

@round pawn use self parameter in your class structures, like this, self.bullet, self.bulletX etc.

[dawn quiver]

I went through the code he has declared self.bullet in the init function

Hello

Is it possible to make a invisible sprite with hit box for collision in arcade

[safe timber]

I notice most people still use pygame. Is pygame better than arcade as far as event handling and processing?

[round obsidian]

@safe timber It's widely used because it's ... widely used, and because it has a lot of tutorials. I can't speak to its event handling and processing

[safe timber]

Based on all my help questions, I’m not sure if anyone figured it out, but I’ve spent a lot of time learning Python to use it for making a fishing game. It’s not a complicated game by any means, but I’m worried arcade or pygame won’t be able to handle it and Godot’s system is too foreign to me.

[round obsidian]

@safe timber I'm using Pyglet, which Arcade is built on, and I have no trouble with events and such.

For perspective, this is the game I'm making

https://cdn.discordapp.com/attachments/660625198390837248/871893087247532042/2021-08-02_19-10-08.mp4

[safe timber]

Are you using basic shapes so you can get the functionality in before adding all the sprites?

[round obsidian]

Basic shapes? I'm not sure what you mean

[safe timber]

The fishing game def won’t be as fast paced. Perhaps I’ll do a little more digging. I’ve seen people in the past make games with just rectangles until they could put in the sprites because sprites usually take the longest.

[round obsidian]

Oh, I see what you mean, yes, you can do that. I had sprites ready beforehand (I'm rewriting an older game that never got all the way through).

You can also use premade sprites from itch.io if you want to save yourself some labor.

But I kept the sprites quite simple for starters, since this was my first game of any kind.

You can also use something like https://www.piskelapp.com/ to create sprites quickly

[safe timber]

Ah, I like the simplicity in fast paced games. It makes them easier to pick up imo.
I think 99% of the reason why it takes me so long to make sprites is because I’m really picky about the way it looks lol I use aseprite for the sprites.

[zinc wing]

Hello i am currently working on a new year countdown (made in pygame), so can i still ask here?

[bleak reef]

yo i does anybody know of a way to make a bunch of enemys without having to blit around 1000 of them

[round obsidian]

@bleak reef depending on the engine you're using, there may be a solution.

E.g., in Pyglet, you can "batch" sprites of a similar type and blit them all at once

[untold jolt]

please help me

[brittle field]

hey can anyone help me ? the smart bomb will not run because when i press the spce bar the bubles will just freze (code lines 142-146) https://paste.pythondiscord.com/ajahedohun.apache

[bleak reef]

@round obsidian im using pygame

[dawn quiver]

Do you mean without having to blit them individually?

What I would do is add the rects of the enemies to a list and then define a function to blit each item in the list

[last moon]

You’re still drawing them 1 by 1 instead of instancing/batching. The only difference with a list is that you’ve got them all in a container 😄

Does pygame not have a better way to do it? Found it: https://www.pygame.org/docs/ref/sprite.html#pygame.sprite.Group

[potent ice]

Any time you can batch draw.. definitely use it

[bleak reef]

ok cool

thanks

[dawn quiver]

Which method is it?

[last moon]

Pygame.sprite.Group

I’m not 100% sure but it doesn’t seem to provide any sort of performance benefit, just utility

[dawn quiver]

Ok thanks 👍

[last moon]

ie not the same as batching

[dawn quiver]

Then is it the same as the pygame.image.blits method?

[last moon]

Probably not?

[dawn quiver]

Functionality wise

[last moon]

I’m not sure actually

[dawn quiver]

This is what the documentation says

[last moon]

Ah no it’s not

Group acts as a container for sprites

Meaning their texture/pos/etc

It’s the same as a list but with added methods like updating the whole list or killing certain sprites

[dawn quiver]

Ok thanks 👍

[dawn quiver]

Btw could you show me an example of this

?

I haven’t been able to get this to work

And I haven’t been able to find one on github

[last moon]

By the looks of it it’d be .blits(texture, image)?

[dawn quiver]

What is texture?

[last moon]

If you want to put it in a specific, area would be coordinates (?)

Your sprite/image of your sprite

[dawn quiver]

What is the -> for then?

[last moon]

That’s the return, if for special_flags you set doreturn to true, it’ll return all rects changed by the blit

[dawn quiver]

Thanks 😄

Oh nice

[novel cobalt]

game idea:

zombie game where the zombies get smarter

they start like generi slow zombies

become fast zombies

start using weapons

get gusn

and pathfinding

and it goes from being zombie survival to zombie fps

any advice to further spice this idea up?

[safe timber]

I would think pathfinding is just a common mechanic no?

[novel cobalt]

yea but the point is the zombies going from making a beeline toward you to kind of moving intelligently and shooting at you and acting more "intelligent"

so the main difficulty increase comes from the intelligeence of enemies

not their heatlh

[feral frigate]

openAI ?

Seems like a openAI project

[round obsidian]

Not really

You can just have two basic behavior algorithms - "dumb" and A*, and whenever you spawn a new zombie you can choose one or the other

and as the game goes on, you spawn more smart ones

or, for each turn of the zombies, you choose whether or not to select a random direction or use A* routing

and as the game goes on you use A* more and more often

[round obsidian]

Latest build of my game https://youtu.be/wIm9A5sfwu0

[lucid fog]

python

[dawn quiver]

I remember from pygame there was a way to handle fps, there was a function that would correct between loops in a while to ensure the updating didn't go say above or below 30. Does anybody know how this would work in a very fine ms basis? Or if its even achievable in python? Otherwise, whats a good way to measure and debug latency. Im working with pygame's midi and im having usses maintaining a reliable clock when sending to output ports and attempting to keep up with bpms over 100.

[small flint]

i would love to get into the building process

[novel cobalt]

not even sure how i am gonna build it if at all so idk

but ya that does kinda soun like an openai project

[round obsidian]

@dawn quiver you typically sample the time it takes for the event loop to complete, and then sleep the remainder

In Pyglet, which is what I use, you can set your event loop to run every xth of a second

on Windows, you also need to set the granularity of the application event timer with a system API, because by default that timer is quite coarse.

# at start of app
import ctypes
ctypes.windll.winmm.timeBeginPeriod(1)
...
# on app exit
ctypes.windll.winmm.timeEndPeriod()

some notes on the API used https://docs.microsoft.com/en-us/windows/win32/api/timeapi/nf-timeapi-timebeginperiod

cool gamedev trick: rather than computing real-time reflections, i just rotated by model 180 degrees on the Z axis, applied a shader to make it fade out vertically, and boom: it looked like a reflection

[round obsidian]

@novel cobalt great trick!
I imagine the shader could also be used to mirror everything past a certain Y point

I love shaders, but I'm bad at programming them

[frozen knoll]

A shader would make it easy to add little wave-like distortions too, and almost free of cost. I think they are hard to learn though, as there are few step-by-step explanations and just a lot of hard-to-read code.

[novel cobalt]

yea - but that's kinda hard lol

i stick to very basic shaders

[novel cobalt]

i suppose - this is more a glass reflection so no distortions for me. But a refraction shader would work well for water.

here's the final thing

this trick was used in early mario games to do reflection

there were actually just two marios

`if mouse.leftclick():
if len(bullets)<100 and shoot_timer>10:
shoot_timer=0
mouse_x, mouse_y = pygame.mouse.get_pos()

        angle = math.atan2(mouse_y-player.y, mouse_x-player.x)

        speed_x = 0.3 * math.cos(angle)
        speed_y = 0.3 * math.sin(angle)

        bullets.append([player.x, player.y, speed_x, speed_y])

`

[normal silo]

dy = mouse_y - player.y
dx = mouse_x - player.x
angle = math.atan2(-dy, dx) % (2 * math.pi)

im alittle confused on this will help me with @normal silo

[normal silo]

To debug things, you need to output something to help see what is wrong, that is a starting point.

But for completeness, here is the working thing so you can see how to get from that start to the end.

import pygame
import math

pygame.init()
screen_size = (800, 600)
window = pygame.display.set_mode(screen_size)
screen = pygame.display.get_surface() 

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

origin = (screen_size[0] / 2, screen_size[1] / 2)

font = pygame.font.Font(None, 30)

bullets = []
shoot_timer = 0

while True:
    time_passed = clock.tick(FPS)

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

    mouse_x, mouse_y = pygame.mouse.get_pos()
    dx = mouse_x - origin[0]
    dy = mouse_y - origin[1]
    angle = math.atan2(-dy, dx) % (2 * math.pi)
    angle_deg = angle * (180.0 / math.pi)

    vel_x = 1.2 * math.cos(angle)
    vel_y = 1.2 * -math.sin(angle)

    shoot_timer += time_passed

    if pygame.mouse.get_pressed()[0]:
        if len(bullets) < 1000 and shoot_timer > 10:
            shoot_timer = 0
            bullets.append([origin[0], origin[1], vel_x, vel_y])

    for i, bullet in enumerate(bullets):
        bullet[0] += bullet[2]
        bullet[1] += bullet[3]
        if bullet[0] < 0 or bullet[0] > screen_size[0]:
            del bullets[i]
        if bullet[1] < 0 or bullet[1] > screen_size[1]:
            del bullets[i]

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

    pygame.draw.circle(screen, (0, 0, 0), origin, 5)
    pygame.draw.line(screen, (0, 255, 0), origin, (mouse_x, mouse_y), 3)
    screen.blit(font.render("Angle (deg): {:.1f}".format(angle_deg), True, (0, 0, 0)), (10, 10))
    screen.blit(font.render("vel_x: {:.2f}".format(vel_x), True, (0, 0, 0)), (10, 50))
    screen.blit(font.render("vel_y: {:.2f}".format(vel_y), True, (0, 0, 0)), (10, 90))

    for bullet in bullets:
        pygame.draw.circle(screen, (255, 0, 0), (bullet[0], bullet[1]), 2)

    pygame.display.flip() 

[lean cosmos]

ive debug it already and everything seems find

i though that maybe the player posititon was updating but it is

[normal silo]

From the starting point, if you had what I had you would notice that when the degrees displayed is say, 90, and you fire, that it goes straight down.

So clearly the vel_y needs to be inverted

Same reason dy is inverted

because in pygame positive y is down

Basically if you have a bug, it can help to build the minimal version of what you need to do with lot's of visual output to help.

Like a prototype.

Start with just outputting the angle

Pasting large amounts of code

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

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

[lean cosmos]

sorry i didnt mean to paste all that

[fading whale]

No worries 👍

[normal silo]

Yeah you can avoid by pasting in their website

[lean cosmos]

https://paste.pythondiscord.com/dotosuzamu.apache

[normal silo]

Ok, so if you look at my code and yours you can spot the differences

[lean cosmos]

ya i seen that you put '-'

on your y

[normal silo]

the dy needs to be negated before being passed into atan2 because it expects y to positive going up

and second, the the speed_y needs to be negated too because same reason

[lean cosmos]

ok

i did taht

[normal silo]

The trig functions want a normal coord systrem with y up

[lean cosmos]

and its doing the same thing

[normal silo]

So you need to map to and from

[lean cosmos]

map?

[normal silo]

Like map in math

Like in this case, -10 for y would get mapped to 10

for example

Have you tried making a new file and running my code

[lean cosmos]

yes i have

and it work perfect

and i debug mine

and there the same

so idk whats going on

[normal silo]

You negated the dy (difference in y between mouse and pos)

?

[lean cosmos]

yse

yes

[normal silo]

and the velocity_y?

[lean cosmos]

yep

-math.sin(angle)

if mouse.leftclick():
        if len(bullets)<100 and shoot_timer>10:
            shoot_timer=0
            mouse_x, mouse_y = pygame.mouse.get_pos()


            xD=mouse_y-player.y
            yD=mouse_x-player.x

            angle = math.atan2(-xD, yD)% (2 * math.pi)

            speed_x = 0.3 * math.cos(angle)
            speed_y = 0.3 * -math.sin(angle)
        

            bullets.append([player.x, player.y, speed_x, speed_y])

sorry

[normal silo]

You flipped it

[lean cosmos]

ya

[normal silo]

atan2 first arg is y

not x

[lean cosmos]

ya but there flip on top

if mouse.leftclick():
        if len(bullets)<100 and shoot_timer>10:
            shoot_timer=0
            mouse_x, mouse_y = pygame.mouse.get_pos()


            yD=mouse_y-player.y
            xD=mouse_x-player.x

            angle = math.atan2(-yD, xD)% (2 * math.pi)

            speed_x = 0.3 * math.cos(angle)
            speed_y = 0.3 * -math.sin(angle)


            bullets.append([player.x, player.y, speed_x, speed_y])

same thing

[normal silo]

screen.blit(pygame.transform.scale(display, screen.get_size()), (0,0))

avoid scaling or anything like that for now

[lean cosmos]

oh i didnt it for the pixel art

did*

so i can scale the window

[normal silo]

Yes, but it makes things more complex, you are drawing in a different space than the whole mouse thing is happening (screen space)

(which means you need another mapping)

Basically, remove things until it works

then add them back until it does not

then ask why

[lean cosmos]

oh ok

i got you it works now

well thanks and sorry it took so long

i didnt think it would affect it but now that you explain it

it makes alot of sence now

[crystal pine]

I need help with pygame on mac

[crystal pine]

#help-croissant

[fast summit]

installing?

for instaling just type pip install pygame on ur terminal

if not work then pip3 install pygame

not then python -m install pygame

u need to install python first

@normal silo can u help with my pygame

i cant keep the window open till i close it

i tried to use the while loop

u know

the running = True

thing

but still it closes

how to fix

[solid meteor]

What does your code look like? You need to update the display within your while loop.

[dim raven]

Hi I know about C++ & C# is it okay to learn pygame without learn python first ?

[solid meteor]

Pygame is a Python library, so no. You'd need to know how to program in Python before you can do anything with Pygame.

[dim raven]

Um alright, thanks for the explanation

[azure badge]

I don't agree this. You can use example pygame scripts with your C# or C++ programs as interoperate.

You should just find the script you want to use

The whole of other processes can be made in side of c++ or c#

[dim raven]

Um that's a good idea but I actually want to learn pygame for my collage assignment because i should create a game from scratch not with full game engine😅

[azure badge]

Hmm okey, however an alternative, you can use any library or the power of python via an another lang 👍

[dawn quiver]

what is more interesting pygame or threejs ?

and can i use pygame for 3d?

thx for ur help (tho u didnt help me) i was opening from cmd

can some one help me understand a very basic thing that for some reason i cant not understand

class Ball:
    """ This class manages a ball bouncing on the screen. """

    def __init__(self, position_x, position_y, change_x, change_y, radius, color):
        """ Constructor. """

        # Take the parameters of the init function above, and create instance variables out of them.
        self.position_x = position_x
        self.position_y = position_y
        self.change_x = change_x
        self.change_y = change_y
        self.radius = radius
        self.color = color

    def draw(self):
        """ Draw the balls with the instance variables we have. """
        arcade.draw_circle_filled(self.position_x, self.position_y, self.radius, self.color)

    def update(self):
        """ Code to control the ball's movement. """

        # Move the ball
        self.position_y += self.change_y
        self.position_x += self.change_x

        # See if the ball hit the edge of the screen. If so, change direction
        if self.position_x < self.radius:
            self.change_x *= -1

        if self.position_x > SCREEN_WIDTH - self.radius:
            self.change_x *= -1

        if self.position_y < self.radius:
            self.change_y *= -1

        if self.position_y > SCREEN_HEIGHT - self.radius:
            self.change_y *= -1

In this code why do i have to do this

 if self.position_x < self.radius:
            self.change_x *= -1

        if self.position_x > SCREEN_WIDTH - self.radius:
            self.change_x *= -1

        if self.position_y < self.radius:
            self.change_y *= -1

        if self.position_y > SCREEN_HEIGHT - self.radius:
            self.change_y *= -1

I cant understand it why

like why change x when it is less than radius ?

[proper peak]

That's how you take account of the ball's radius when reflecting it off a wall.

Consider what the x-coordinate of the ball is when it's touching the wall.

[supple cargo]

For that wont it choose the position_x of the ball

and the

corner

such as like ```py
if self.position_x = SCREENWITDH:
self.change_x *= -1

I have set Screenwitdh before hand which is 600

[dawn quiver]

i actually wanna try pygame to make a game for the last project from my school, but i think it could be more easier and nicer if i use javascript or webgl like threejs or something what do you think? and i also wondering can other people play our game without installing python first?

[exotic laurel]

I haven't tried javascript or webgl before so I can't tell you it's performance ratio but I've worked with pygame for so many times and it has not disappointed. If you take a look at pyinstaller and NSIS for packaging and deployment - you can distribute the software as an installer or a .exe using them (no preinstalled python reqs).

[dawn quiver]

so what should my friend do if they want to play my game? installed?

[exotic laurel]

If you choose to distribute is as an .exe, that means they needs Windows as their OS and run it directly

If it's an installer, install it and run it-

[dawn quiver]

and how many month i can make game using pygame? because the deadline for my project is only a year

[exotic laurel]

You can make games with pygames until the end of time - but for the learning curve, it's quite spread out, it also depends on how much you know python

a year is a good deadline

[dawn quiver]

how about 3d game with pygame? i think its more easier i do it on web

[exotic laurel]

Ah so, pygame doesn't support 3D games

[dawn quiver]

idk

[exotic laurel]

It's a simple wrapper for SDL, a 2D api.

[dawn quiver]

never try

[exotic laurel]

Yeah, it doesn't support 3D

If you want to use python, there are other options like pyglet that does support 3D

[dawn quiver]

alright thank you so much

[exotic laurel]

np

[ionic ember]

SDL is not 2D

[exotic laurel]

It is, it just has some helper functions that goes with Open GL (if you need 3D - but pygame doesnt have it i suppose)

[ionic ember]

Thank you, can you PM these to me so I can check it later

[exotic laurel]

np!

[sand forge]

Hullo

Can anyone help me?

[exotic laurel]

ask away

[river sphinx]

Yea? @sand forge

[sand forge]

Basically

Im making a tezt based adventure game for a school asigbmebt

And

I wan it so when the person playing dors a command or soemthing that says save

Python quits and saves a state so that when they come back they start from that point

In the code

[river sphinx]

But, you are using game engine?

[sand forge]

Nope

just pycharm

[tight pewter]

I am using Ursina and I have programmed Minecraft. I have build a house there, but is there a way to save the world?

[river sphinx]

I dont think so... but maybe

Try searching on google

[exotic laurel]

That's pretty nice, maybe try to see how minecraft itself saves worlds efficiently and try to replicate something similar

[exotic laurel]

So yep, just save that state - and add a check before a game starts so that you can skip the stages that the adventurer have already been through

[tight pewter]

ok thanks

[sand forge]

How?

[exotic laurel]

You can save the state by writing onto a text file, or other alternatives if you wish, and then read the file on start-up

[sand forge]

Ok

So

How does it know where the user ended off

[exotic laurel]

you will have to make a check, for example, you can number all the levels present, if the text file returns 3 you can skip the first 2 levels

[sand forge]

U@

So

Do tou want to check my file?

Cause

This is a wierd way i did it

[exotic laurel]

Yeah?

[sand forge]

I can screenshot or send u the file

[exotic laurel]

can you send it here
