[lilac mirage]

just for knowing

[potent ice]

2D? 3D?

Doesn't matter?

[lilac mirage]

2d

[potent ice]

Maybe just start with arcade because it's simpler / higher level : https://arcade.academy/

[lilac mirage]

is arcade a module

in py

[potent ice]

Also a book : https://learn.arcade.academy/

Yes it's a module you install

[lilac mirage]

ok thanks

[potent ice]

Just like pygame, pyglet etc etc

[lilac mirage]

👍

[potent ice]

Maybe more accurate to call it a python package.

[last moon]

Sorry I feel like I’m missing something here, the primitive sent to the fragment shader as it’s input? Is that what’s used to draw them or is there another process in between

[potent ice]

The fragment shader runs per pixel for the primitive (for example a triangle).

What happens from the vertices leaves the vertex shader and the execution of the fragment shaders are out of your control really

(At least in OpenGL. Vulkan and other lower level APIs have a more fancy pipeline)

If you are rendering a triangle with 3 different colors per vertex the color value arriving in the input (frag shader) will interpolate by default.

This is common to see in the OpenGL "hello world" RGB triangle

https://pbs.twimg.com/media/DgKO8H0WAAIteGU.jpg

Three vertices as input and rendering using triangles mode. Each vertex has a different color

This interpolation makes more sense when we are using texture coordinates and normals

[last moon]

Ah ok I was just going to ask about vulkan

[potent ice]

Barycentric coordinates are used under the hood.

[last moon]

So the fragment shader takes in the properties of each vertex and the gpu interpolates + returns the colours to send to the screen?

[potent ice]

With lower level APIs like vulkan you kind of "build" your own pipeline. In OpenGL the pipeline is more fixed with optional features.

Example: You can add a geometry shader to the program what will be a proxy between the vertex and fragment shader. It can create or destroy geometry on the fly. It takes primitives and input instead of vertices

.. and tessellation shader that can dynamically subdivide the primitives if needed

This pipeline works pretty well, but it less flexible.

Lower level APIs can simplify a lot more. You have a concept of "mesh shaders" for example that are much more flexible than the geometry and tessellation stages.

You can set up the exact GL pipeline in Vulkan if you want. Not a problem

Even use the same GLSL shaders you used in OpenGL

[mortal dragon]

That's actually pretty neat idea :)

[potent ice]

I think kids are super creative if you just get them started on ideas. Just have to try to boil it down into something that can be created

We just used arcade for that project. It was under 100 lines.

The built in collision detected makes it super simple

[last moon]

That was my understanding of vulkan that you have to set up the pipeline in the first place but the trade off was that the custom pipelines allow you to stream/render geometries without having to stray into ram/streamlining the vram used

[mortal dragon]

Ok cool will see what can think of

[potent ice]

More or less that + wider platform support + can use threads and more.

The OpenGL context belongs to a process/thread. Access from any other location is forbidden

.. but shared contexts can be created ... BUT only primitive objects such as buffers and textures are synced between them. No container objects such as vertext arrays and framebuffers

It's a huge advantage to know OpenGL pipeline well before moving to vulkan imho

[last moon]

And that’s what can cause a bottleneck? Or does it restrict more than just speed?

That’s my plan tho, I’m thinking of doing a 2D engine in python to get the basics, doing one in gl and then doing on with vulkan if I haven’t given up by then

[potent ice]

That and call overhead. With a more flexible pipeline you have more freedom to optimize and cause less round trips between cpu and gpu

[last moon]

Maybe one in rust too

[potent ice]

In gl you can use the indirect draw commands to avoid a lot of the overhead

[royal nymph]

hey im new to python pygame

[last moon]

I’m assuming the regular ones call the indirect commands?

[potent ice]

Nope

glDrawArrays/Elements are separate draw calls. It can handle instancing at least.

[grim abyss]

what's the easiest way to get into 3d with python?

[last moon]

I should stop assuming thing I think I’m like .5-8 at this point

[potent ice]

While the indirect draw commands can have thousands of draw call parameters packed into a buffer on in vram instead

@grim abyss Probably Ursina

[last moon]

What’s the overhead that’s being avoided then?

[potent ice]

The call overhead in drivers

We're talking about things on the nanosecond scale here. Consider someone playing a game in 244hz. You don't have much time

[last moon]

From calling it through the cpu?

[potent ice]

Yep

[last moon]

Ohh ok but the way the gpu handles those calls can’t be changed with gl?

[potent ice]

Yeah you just have these functions exposed and no other control. It's up to the drivers what happens.

OpenGL is also a giant state machine. There are probably a lot of sanity checking and whatnot done by these commands.

Instancing was the first step to get rid of overhead.

then indirect draw...

Indirect draw means you have to prepare absolute everything before issuing the draw call of course. This can be done asyc while the gpu is rendering the previous frame for example. It's a double win in many cases.

[last moon]

So back to this, they don’t explicitly send anything to the gpu, gl handles that?

[potent ice]

Ah no you do write data to buffers in gl as well. But only when they need updating. A static 3d object only needs to be written once

The challenge in gl in implicit sync causing stalls. If you read or write to a buffer the gpu is currently working on the entire apolication will stall until the the gpu is done

[lost stirrup]

I am very new to python can anyone help me how to make a code run for a certain amount of time and then stop?

[true seal]

There is a time module I believe

[potent ice]

That needs a lot more context

[lost stirrup]

I mean pygame srryy

[potent ice]

You can of course use time.sleep(10) to wait 10 seconds, but this stalls everything else. How this is done really depends on the context

[azure mantle]

How is there an error here
https://prnt.sc/10o2ymm

[potent ice]

It's just vscode not finding pygame. Click the "Python 3.7.2 64-bit" in the lower left corner and see what appears

[azure mantle]

nothing appears

https://prnt.sc/10o31od

that does actually

[potent ice]

In pygame you would have a main loop. You can import time and use time.time() to get the current time when the program starts and measure how many seconds have elapsed using time.time() - start_time

Add some print(..)s to see what is happening

[azure mantle]

me?

[lost stirrup]

thank you man I will try

[potent ice]

Terminal -> New Terminal

type python and then do import pygame

[azure mantle]

alr done

still error

[potent ice]

the program runs without error?

[azure mantle]

mhm

yeah it does

[potent ice]

hmm. Just restart vscode maybe?

[azure mantle]

ok

nope same error lmao

everything goes smooth tho

[lost stirrup]

Can you give me an example pls I don't really understand

[azure mantle]

i made a display and it doesn't display and error

when run

[potent ice]

import time in the top and print(time.time()) in your draw loop

[potent ice]

It's just vscode not understanding what pygame is I guess. It does not affect your program at time time

[azure mantle]

alright thanks

[potent ice]

You could see if the pylance mod (different language server) handles it better.

[azure mantle]

alr

[potent ice]

or you might need to do something special if you have anaconda installed

Give vscode a minute to initialize everything properly

[azure mantle]

alright

import pygame

#starting pygame
pygame.init()

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


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

Still same errors and it actually does fuck up the code

[drowsy rampart]

display update where

pygame.display.update()

[potent ice]

You could create a virtualenv for your project. That might fix it. I always use a virualenv so I have not seen this problem before.

[wet folio]

I'm trying to use pygame and pynput to create a little program. I basically use pygame for the GUI as I'm more used to use pygame then tkinter/pyqt. I set up a mouse listener with pynput but whenever I click on pygame window's title frame the program freezes for 1-2 seconds.

from pynput.mouse import Listener as ms_listener
pygame.init()

win = pygame.display.set_mode((300, 300))


def on_click(x, y, button, pressed):
    print("Clicked")


mouse_handler = ms_listener(on_click=on_click)
mouse_handler.start()


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

pygame.quit() ```

Is it possible to move the (0,0) point to another corner?

And make y go up when going up?

[young vault]

My game in linux gets around 59 fps usually but in windows it only gets 50 fps average (on the same machine)
any way to fix this?

[last moon]

can you not just use futures to deal with that?

[abstract light]

quick question. Has anyone ever used a tile map editor and combined it into pygame?

[mint zenith]

Yes

If you mean implement the editor into the game, then no. But using a map exported by the editor, yes.

[peak tangle]

I am a student and I was wondering if someone can do a rock paper scissors project or if someone has already done it

[shrewd patio]

@peak tangle Here's a tutorial on how to make a simple text-based game: https://realpython.com/python-rock-paper-scissors/

[waxen ocean]

rock paper scissors is a cool project

[woeful brook]

😂

[lethal hinge]

I had an idea for a command line based puzzle game, but I can't figure out a way to hide the answers such that the player can't open the python file and just find the answers right away. Any suggestions of how to hide this stuff? It'd be like basic text passwords (Or the most advanced idea I have, it creates a .wav file with a message hidden in the spectrogram in a steganography like way)

[proper peak]

Right away? Just encode them in some way. base64 would be one solution, though you can also use actual enctyption (in which case the cheating player will need to find the data, find the key, and write a program to decrypt the data with the key).

[lethal hinge]

Maybe I was over thinking it, I was imagining complicated ways to do it and that wouldn't have made much sense. But won't I need to include a way to decode it in my own code? Or would that be too complicated for a cheater to extract easily?

[proper peak]

Yes, you would

So another way to extract would be to use a debugger to extract the decoded phrases at runtime.

There's no way to make it even hard to extract the phrases, really, you're just filtering out people who can't read Python code.

[lethal hinge]

Hrm, alright then. That makes sense, I'll just go for some almost tedious route to weed out any cheaters and then it'll be for ease for me. Thanks!

[proper peak]

well, actually there is a foolproof way to hide the answers if your answers need to be exact

like, if a question has one or several possible answers which need to match exactly and there's no fuzzy matching whatsoever

In that case, you can instead of storing the answers, store the hashes of the answers.

[lethal hinge]

Oh the closest it'll be will be str.lower() so no fuzzy

[proper peak]

then yeah, you can totally do that

[lethal hinge]

So what's a hash? That's a new term to me

[proper peak]

Most generally, a hash function is a function that generates a fixed-size output from arbitrary-size input

Usually you also want it to have certain cryptosecurity qualities, but that's the general one

This transform is not reversible - it's not one-to-one, either (obviously), but for modern hash functions there doesn't exist a good method of determining data by hash(data) without bruteforcing all possible inputs until you find one the hash of which matches.

[lethal hinge]

So say my password is abcd and someone guesses abc, their hash would be like 6 but the answer is 10 (assuming It's letters having values?)

[proper peak]

So if you store, say, SHA256 hashes of your answers, you can check an answer by calculating its hash and comparing it to the stored ones - but you can't tell what the answers are by the hashes without tons of bruteforce

[lethal hinge]

Is a hash not comprehensible by a person when written down?

[proper peak]

It's a random-looking (literally: cryptographically secure hash functions tend to produce outputs with close to perfect entropy) binary string, so yeah.

[lethal hinge]

Like say the possible inputs are one of [Apple, Banana, Cherry] I'm trying to figure out what I'd have to put into the code.
To put an answer in a set in the code I might, say, run print(hash('apple)) and then I copy that in as an answer into my actual code?

[proper peak]

!e

import hashlib
res_hash = hashlib.sha256("dasdas".encode("utf-8")).digest()
# this is a binary string:
print(type(res_hash), res_hash)
# hexadecimal representation of it (that's how the hashes are usually presented, as this is human-readable)
print(res_hash.hex())

[frank field]

@proper peak :white_check_mark: Your eval job has completed with return code 0.

002 | 2ed46d7bedc17aba18343eac71e21648b1af50fff732af7e338075cd0ed1567a

[proper peak]

But you can't tell, having 2ed46d7bedc17aba18343eac71e21648b1af50fff732af7e338075cd0ed1567a, that it is the hash of dasdas without bruteforcing the SHA256 hashes of various inputs up the to length of 6.

[proper peak]

Nah, the hash function from Python is...different - it produces very "obvious" results for simple objects, you want something cryptosecure.

[lethal hinge]

So that last string of random looking numbers is what I'd put in
answers = [abitrary string of SHA256 res_hash.hex()]
And then
if hashlib.sha256(input_).hex() == answers[0] and that should work?

And yeah the hashlib does look more cryptosecure I'll agree

[proper peak]

!e

import hashlib
ans_lst = ["Apple", "Banana", "Cherry"]
hashes_list = [hashlib.sha256(ans.lower().encode("utf-8")).digest().hex() for ans in ans_lst]
print("List of hashes of lowercased answers:")
print('\n'.join(hashes_list))
print()

attempts = ["ApPle","bananan","cherry","adjasodas"]
for ans in attempts:
    print(f"Attempted answer:{ans}")
    ans = ans.lower()
    print(f"Lowercased attempt:{ans}")
    ans_hash = hashlib.sha256(ans.encode("utf-8")).digest().hex()
    print(f"SHA256 hash:{ans_hash}")
    if ans_hash in hashes_list:
        print(f"This hash is in the list!")
    print()

[proper peak]

here's an example of calculating the hashes of correct answers and checking an answer

the hashes_list is what you'd put in your program

[lethal hinge]

Ooh ok. Thanks a bunch! I'll definitely use that

[proper peak]

(Well, hashes_list here is a list of valid answers for a single question. So in total you'd have a list of lists - a sublist of valid answers for each question (maybe 1-element))

[lethal hinge]

Yeah, I may even end up with them buried in a json of answers but idk if I'll have enough for that to be worth it

I've gotta go to bed now, but thank you for helping me figure that out. Goodnight/good time appropriate phrase!

[sharp thistle]

hey any suggestions for a school project ? ty in advance

[drowsy rampart]

How to make window resize menu in pygame for example like that?

[sharp thistle]

which gui are you using via that in a drop down list and these buttons each button will resize the main window

[dense ether]

Made my own paint with pygame, storing pixel color and pos to list is probably bad idea because its so slow, shoud i use dictionarys or numpy arrays or something else?

[drowsy rampart]

can I make it in pygame itself?

[sharp thistle]

no idea never tried it

[dawn zinc]

hi guys

im new to this server

[tawny jolt]

Hii

[dawn zinc]

just wanted to ask a question

[tawny jolt]

I need a help

[dawn zinc]

is it possible to use flutter with python?

[tawny jolt]

Can anyone tell me how to extract any game files or open the game project in unity?

[dawn zinc]

i dont know sorry :/

[tawny jolt]

Okay sir!!

[dawn zinc]

you using unity with python?

is it possible?

[abstract light]

@mint zenith how do you do it

Woah wait

Who is using Unity with Python

Are they using a third party?

[crisp junco]

Whoa! Can you do that?

was Mark doing that?

[dense ether]

if u guys wanna check, here is the code. I'd love to hear feedback and learn what I could have done better.

[severe saffron]

Wait so you have a dict of pixels?

But like

You need a pixel value for every pixel

So why not have a list of every pixel on the screen then just change the one you want

[dense ether]

I stored them in list ((x),(y),color)

Oh yeah so thats just what i did

[dense ether]

U can read / test it

Id love to have comment

[dawn quiver]

Ummm so new to game development on pyrhon.... any suggestions

Or tips or a tutorial

[potent ice]

Just simple 2D stuff?

[dawn quiver]

Most likely as a start so yea... I wanna start 2d and maybe when used to it go 3d

[potent ice]

Could start light with arcade? https://arcade.academy/

[dawn quiver]

Okay I'm at work but got like a hour and 30 min, but do I need py.game?

[severe saffron]

no, i'm saying store them in order

[potent ice]

What is py.game?

[severe saffron]

if your resolution is 300x300, then a 90000 long list/array of colours

in your case, you have to lookup in an entire list of pixels for the one you want

[dense ether]

Pygame is pythons 2d game library

[potent ice]

If you mean pygame, then no. Arcade is a higher level 2D game library. You should be able to easier pick up pygame after playing around with arcade first.

[dawn quiver]

Ph

Oh*

[potent ice]

If you want to test out some higher level 3D stuff later you can try Ursina

[dawn quiver]

Okay

Also using visual source code...like it's on my computer

[potent ice]

Pygame is if course also an option, but arcade is much simpler to start with

[dawn quiver]

Okay

[dense ether]

I have them stored in list in order. I not sure what u meam.

For i in range(width);
   For j in range(height):
      Pixels.append((i,j))

[severe saffron]

but why do you need to store the pixel coordinate with the colour

a pixel buffer is normally just a list of every pixel value in order

no lookup, no extra data stored

[dense ether]

U meam ppl should learn/ start using arcade and after that use pygame or just skip

[dense ether]

Ah okey, i see

[severe saffron]

so to access pixel at x,y

[dense ether]

I didtn even think that

[severe saffron]

you do something like pixelbuffer[y*row_width + x]

[potent ice]

That really depends on what kind of games they want to make and for what platforms. Arcade is a great introduction. I assume they will have more knowledge later to pick the right library for their projects.

[dense ether]

What u would think, should i move from pygame to arcade?

[potent ice]

Depends. It's higher level and might have some limitations because of it. Also it's using the gpu making it harder to run on older hardware.

The nice thing with pygame is the compatibility.

The positive with arcade is that it's using the gpu and can be a lot more powerful

It's all about pros and cons 😉

[azure mantle]

The enemy is duplicating instead of just moving can somebody please help fix that?

Code:

pygame.display.set_icon(icon)

player_img = pygame.image.load('player.png')
playerX = 370
playerY = 480
playerX_change = 0

enemy_img = pygame.image.load('enemy.png')
enemyX = random.randint(0, 800)
enemyY = random.randint(50, 150)
enemyX_change = 0.3
enemyY_change = 0

def player(x, y):
    screen.blit(player_img, (x, y))


def enemy(x,y):
    screen.blit(enemy_img,(x,y))


running = True


screen.fill((0, 0, 0))

while running:

        if event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                playerX_change = 0

    playerX += playerX_change

    if playerX <= 0:
        playerX = 0
    elif playerX >= 736:
        playerX = 736

    enemyX += enemyX_change

    if enemyX <= 0:
        enemyX_change = 0.3
    elif enemyX >= 736:
        enemyX_change = -0.3


    player(playerX, playerY)
    enemy(enemyX, enemyY)
    pygame.display.update()```

Please mention me if you know the solution.

[dawn quiver]

Can someone program a tank game for me in scratch?

[unkempt wren]

what is scratch?

remember, if you need something done, the goal is to learn how to do it yourself. And people here will help you learn.

[dawn quiver]

Yeah thats true, its a Program like for beginners to "program" with most done commands, like you can make mini games without a "real" code

[gilded grove]

Isn't this server for Python

[unkempt wren]

this server is for learning Python

[gilded grove]

not Scratch

[unkempt wren]

@gilded grove please do not mini-mod

[dawn quiver]

Oh okay sry

[abstract light]

How does it work?

[ruby flame]

does anyone know how to make a scrolling background in pygame

[mint zenith]

That's a broad question and I'm not sure what kind of answer you're expecting. The docs show examples, so you can start there. I used it with pyscroll which took care of rendering the map for me, but you may not want to use that if you're not building a side scrolling game.

[abstract light]

ok so '

forget about unity because I want to stick wtih Pygame

My main question right now is that

I have a file made in a program called TILED. And I want to bring it into pycharm and read it

it's a map

how do I do this

[mint zenith]

With pytmx, like I said.

You need to export the map from tiled into the tmx format.

[abstract light]

but somepeople said

csv

file

and I'm building a game that is anyway scrolled if you know what I mean.

Like the player will always be in front of the screen. He will move forward or whatever and the background will also move

or the camera

the camera will always be facing him.

I need help on making this

@mint zenith

[mint zenith]

Okay, then look into pyscroll

It can load maps through pytmx

I don't know what csv files have to do with this

[abstract light]

that's how some people loaded the map

[abstract light]

So

Pyrex

Pytmx

Is it a library?

@mint zenith

[dawn quiver]

for event in pygame.event.get():
if event.type == pygame.KEYDOWN
the event.type comes from the pygame.event.get() which the first parameter is type, no?

[abstract light]

the parameter?

@dawn quiver

what exactly are you trying to do

[dawn quiver]

pygame.event.get()
get events from the queue
get(eventtype=None) -> Eventlist
get(eventtype=None, pump=True) -> Eventlist

[abstract light]

are you trying to make a hot key?

[dawn quiver]

So I saw this code in the documentation of pygame:

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

[abstract light]

like if k pressed then do this

[dawn quiver]

And I wan't to know what's doing the type? like where it comes from

[abstract light]

as far as I have understood pygame I'm pretty sure it means the keys

like what type of key

k or j or something

that's what I took it as

[dawn quiver]

yeah so basically pygame.event.get gets the hotkeys yeah?

[abstract light]

yeah

[dawn quiver]

event spams each input/output of the keys yeah?

[abstract light]

you can combind them I think

no

it just get shte in put

[dawn quiver]

oh yes sorry

[abstract light]

yeah

you have to put a colon and the put the if key what ever then do this

[dawn quiver]

and then the type process the current key pressed and compares it with the keydown?

[abstract light]

yeah

if you want the event key a

then you do key_a or something and then do a collon

wait let me show you

this is what I did

[dawn quiver]

yeah ik that

I'm just wondering

if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:

if event here is taking a parameter that's inside of the pygame.event.get()

which seems like it's doing

bcs a event.type will be keydown

[abstract light]

yes

[dawn quiver]

and the specific one which is key will be, K_LEFT

[abstract light]

yeah

[dawn quiver]

okay, I understand know

Thx m8

[abstract light]

keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
self.speedx = -5
if keys[pygame.K_RIGHT]:
self.speedx = +5
if keys[pygame.K_UP]:
self.speedy = -5
if keys[pygame.K_DOWN]:
self.speedy = +5

[dawn quiver]

oh

that's really good as well

basically u put all the keys inside of a list? and if theyit matches do x

no?

[abstract light]

I put them in the game loop

so I will do

[dawn quiver]

do u know how the data is structured in pygame.key.get_pressed, so u can use a list as an identifier?

[abstract light]

while run:
#put the screen  
keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT]:
            self.speedx = -5
        if keys[pygame.K_RIGHT]:
            self.speedx = +5
        if keys[pygame.K_UP]:
            self.speedy = -5
        if keys[pygame.K_DOWN]:
            self.speedy = +5
#update player

this will be the main game loop

it will keep on running

[dawn quiver]

yeah, looks good

[abstract light]

i try

[dawn quiver]

I had this one

[abstract light]

meaning

[dawn quiver]

for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    x1_change = -snake_block
                    y1_change = 0
                if event.key == pygame.K_RIGHT:
                    x1_change = snake_block
                    y1_change = 0
                if event.key == pygame.K_UP:
                    y1_change = -snake_block
                    x1_change = 0
                if event.key == pygame.K_DOWN:
                    y1_change = snake_block
                    x1_change = 0

[abstract light]

nice

[dawn quiver]

I'm just breaking down the code of a snake game and figuring out how it works

[abstract light]

smart

[dawn quiver]

I want to see how the pygame.event.get is structured

any idea on how I can look into it?

[abstract light]

I like how everyone just makes games by following tutorials but has no idea what the functions do

well not everyone

what do you mean?

[dawn quiver]

so basically

in pygame.event.get

there's a certain type and keys, so I want to see how they are arranged

and which dataset they r using etc...

[abstract light]

you mean what each key has?

like what it is called by?

[dawn quiver]

and how they code it as well

like inside of the library

check the code

[abstract light]

oh here wait

https://www.pygame.org/docs/ref/key.html

this shows the keys and explains

@grim abyss do you have experience in pytmx

[dawn quiver]

and is there anyway that I can check inside of the pygame library in my computer? to see how they implement the hotkeys and everything?

[abstract light]

you mean you want to see how they made those K-left things?

[dawn quiver]

yeah

to understand how from the system the catch it and implement it

[abstract light]

I don't really know how to look into the pygame library and see how they made up the K_left thigs, but your best bet is going to the pygame.org

[dawn quiver]

okay thx a lot

I will work w what I have

[abstract light]

ok

sorry

[grim abyss]

@abstract light never heard of it before. I was just looking at the pytmx site/docs though. seems like a useful tool...

[abstract light]

Do you know how to put a map in Pygame? Like an easy way? And one that does not fully occupy the screen? I want the player to explore the word

Wolrd*

Not see the whole thing in one sec

@grim abyss

[grim abyss]

@abstract light you need a scrollable map. Check here for an example: https://github.com/bitcraft/pyscroll

oh that's not an example. it's a module.....

well it's both haha

@dawn quiver hey buddy. what is it your trying to discover about pygame?

[abstract light]

I made a map I Tiled

In*

@grim abyss

[grim abyss]

ok i got the 'i made a map' part parsed but after that my parser crashed...

[abstract light]

In Tiled*

@grim abyss

[grim abyss]

what's tiled

tile map generator?

[abstract light]

It’s something to make sprites and stuff

So when I make how do I export it and use it with Pygame

@grim abyss

[grim abyss]

you're asking me?

[abstract light]

Yeah

[grim abyss]

we have something for this in our language. It's this ---> ?

[abstract light]

Do I use csv format or something

[grim abyss]

denotes a question..

lol

:-p

[abstract light]

XD

Sorry

[grim abyss]

ummm

what options does tiled give you for export?

besides csv

i honestly don't know...i've never used Tiled and I haven't used much of pygame

[abstract light]

I remember just that

Have you ever made a tile map and used it in Pygame

@grim abyss

[grim abyss]

no

but it shouldn't be difficult

[abstract light]

K

[abstract light]

@silk zephyr Have you ever made a tile map and used it in Pygame

[silk zephyr]

not in Pygame, sry

[abstract light]

Ok

@lucid matrix Have you ever made a tile map and used it in Pygame

@quick jay Have you ever made a tile map and used it in Pygame

@valid wadi Have you ever made a tile map and used it in Pygame

[valid wadi]

I have used pygame once ever, and didn't make a tile map.

Please don't ping random people.

[abstract light]

I’m asking people in the helper group

@valid wadi

[valid wadi]

please don't ping random helpers, either.

[potent ice]

Anyone can answer these questions. No need to ping. People answer when they have time. Using tile maps is also a very narrow subject most people don't have much experience with.

hello guys, Hope you're all good, do you think that pygame is a viable option to create a small RPG game, or should i use something else?

[flint surge]

Pygame is great for 2d games, I'n pretty sure that you can have online gameplay with pygame, python is not really meant for game develoment. I reccomend you try Unity

[violet kraken]

Thanks, i want to make a pixel art rpg game but im a complete beginner, and since i know python i was trying to check if it was good

[fathom helm]

guys

how am i supposed to start game development in python?

Im new

[drowsy rampart]

If you already know python syntax then

First this https://www.youtube.com/watch?v=jO6qQDNa2UY

and then when you try to do your own game your only friend is Stack Overflow

simpliest way, good luck

more advanced way is learn in pygame site itself and read its documentation...and also there is not only pygame library but Arcade as well

[dense ether]

In pygame library used mainly for 2d game, how should i make walls? Should i make them py coordinates or mayby backaround img pixel color, these are ideas that i found, is there beter way to do this? Thanks for reading

[drowsy rampart]

Panda3D is for u

but for 3D it's better to learn Unity

[mental sorrel]

yeeea

[dense ether]

Banda3d for 2D dev?

[frozen knoll]

@violet kraken You might also look at Arcade at another option. Https://Arcade.academy

hey im making a game

im having some problems

1 is that theres duplicate letters in the board
and the second is that the game isnt working meaning its not accuretly telling me if the letter i landed on is p1s or p2s and isnt being replaced with a dash

the goal of the game is you roll dice

dice are a coullum and a row point

so 3,4

would be 3rd row and 4th collum

if it lands on p1s letter it get replaced with a dash

if on p2s replaced with a dash but then its p2s turn

@restive lantern

Don't use tkinter to make games, this is an XY problem.

[potent ice]

Yup. Use a game/graphics library instead

[wraith vapor]

What's an XY problem?

[wraith vapor]

Could you recommend a game/graphics lib please?

[normal silo]

https://en.wikipedia.org/wiki/XY_problem

[wraith vapor]

Thanks!

[normal silo]

2D, 3D, or both (requires effort on your part to do the rendering how you want it)?

[wraith vapor]

What's a good 2D lib and what's a good 3D lib?

[normal silo]

2D: pygame / arcade / pyglet 3D: ursina / panda3D / moderngl (with moderngl-window).

Probably forgetting something, but those are not bad.

Note: Ursina is built on top of Panda3D with the aim of simplification (small layer on top of it).

[wraith vapor]

Great, thanks for the recs!

[ruby flame]

I am just curious how do you unblit something in pygame

[normal silo]

Define "unblit".

[ruby flame]

like unrender something from a screen

[normal silo]

Define "unrender".

[ruby flame]

remove a image

[normal silo]

You paint over the image with whatever the background (predicted values) behind that image would be.

[ruby flame]

well wouldn't it cause the issue of lag

[normal silo]

That depends, in almost every case someone can't preemptively tell you whether or not it will lag (there is no information to go off of).

[ruby flame]

well isn't there anyway other way instead of painting over

[normal silo]

It depends on how the image that you want to modify is represented.

If it's an array of pixels values, then no.

[ruby flame]

it is this thing

[normal silo]

To modify the image.... you need to modify the image...

[ruby flame]

well I want to create a lazer on press then remove it when it hits something like a projectile

[normal silo]

So it's an XY problem. Should have just asked for that in the first place.

The answer is that you clear the entire screen (or whatever surface you are doing this on) every frame, and then just paint the things that exist in the scene (if the laser hits something, remove it from the scene).

[ruby flame]

what function is where you clear the screen

[normal silo]

context?

oh nvm

pygame

[ruby flame]

you said "The answer is that you clear the entire screen "

what is the function for that in pygame

[normal silo]

Just fill the screen with a solid color.

[ruby flame]

okay but I don't want to complety remove the background I already have

just the lazer

[normal silo]

just draw the background again

[ruby flame]

maybe give me example code

[normal silo]

fill screen
draw background
draw laser and other stuff

[ruby flame]

um in python

[normal silo]

https://riptutorial.com/pygame/example/14697/a-simple--game-

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.

https://paste.pythondiscord.com/evilumecip.properties

[normal silo]

Oh so your question is about detecting input and then spawning a laser which does collision detection?

[ruby flame]

yeah

[normal silo]

Hmm, this turned into an XYZ problem.

So it's actually 3 questions.

[ruby flame]

also how do I now when to remove the lazer

[normal silo]

question 1: how to detect input, question 2: how to spawn a laser (and keep track of it) and question 3: how to do collision detection.

This will be long, so open a help channel.

[blissful depot]

Why do you use pygame and stuff instead of just using turtle?

Turtle can load images, can measure distance etc.

[mint zenith]

Turtle is far more basic in terms of graphics. I don't think it was designed for games. It's also quite clumsy to use for something as complex as a game.

[blissful depot]

Hmmm...

[mint zenith]

If you look at the feature set of something like pygame, you'll see it has many more facilities that are useful for creating games

Like getting user input, playing audio, sprites, etc.

[blissful depot]

Oh. Ok.

[mint zenith]

I imagine turtle's performance would also be quite poor for games, but maybe I'd be proven wrong. Haven't tried for myself.

[blissful depot]

Ok. Thanks @mint zenith

[shrewd copper]

Anyone else chillin here while they mess around with pygame

[true dagger]

?

[shrewd copper]

I have 0 experience with turtle, but I believe you'll need to set the perimeter for the turtle by having a statement that changes the turtle's movement when it reaches the border you want to set. For instance,

      turtle.change_x = 0```

[frank field]

Missing required argument

package

[blissful depot]

I think that that would work

@abstract light said something similar too

[abstract light]

Yeah @blissful depot I did

[dawn quiver]

@blissful depot Turtle = graphics library for beginners. as mark said, its too clumsy and isnt fit for game dev. pygame allows you to load images and measure distances too. ive tried turtle and got it the hard way. believe me do not try turtle for game dev.

[blissful cape]

Hey is there anyone who could help me with saving data in pygame and then loading it back when the game is activated again so highscores will be saved?

[dawn quiver]

Hey, do you want to save it for only one user or for multiple users?

[blissful cape]

right now for only one user

[dawn quiver]

Okay so for one user you can just save it in a simple .txt files, when tracking multiple users / or data to track I'd recommend json file format.

hs = 200
with open("highscore.txt", "w") as file:
    file.write(str(hs))

to save it

with open("highscore.txt", "r") as file:
    hs = int(file.read())

to read it

[blissful cape]

anything else i should do? Because i copy pasted this in to my code and it doenst save it yet? I sent you a friend request, if you dont mind i can screen share in dm?

[dawn quiver]

Are you sure the code is executing? It works on my system

[blissful cape]

Yeah im sure like it creates the file and the file says 200 but it doenst do antything with the stats saved in my code, could be my problem but i dont know how to save my stats to the file

[dawn quiver]

oh right, 200 is just a random number I chose. you'd need to change hs to the variable you're using

Do you use a integer or something else to track the highscore?

[blissful cape]

def update_score(score, high_score):
if score > high_score:
high_score = score
return high_score

high_score_surface = game_font.render(f'High score: {int(high_score)}', True, (255, 255, 255))
high_score_rect = high_score_surface.get_rect(center=(288, 850))
screen.blit(high_score_surface, high_score_rect)

[dawn quiver]

!code 👇 btw you can format your code like this

[frank field]

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

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

[blissful cape]

def update_score(score, high_score):
    if score > high_score:
        high_score = score
    return high_score

high_score_surface = game_font.render(f'High score: {int(high_score)}', True, (255, 255, 255))
        high_score_rect = high_score_surface.get_rect(center=(288, 850))
        screen.blit(high_score_surface, high_score_rect)

[dawn quiver]

so yeah can just change hs to high_score and add the code I send you to your update_score function

You'd read the highscore in the file, compare it like you already do and if the score is higher you can overwrite the current high score in the file

If you have any question about the syntax or what's not understandable feel free to ask

[blissful cape]

Could i show you in dm?

[dawn quiver]

I'd rather not dm

[blissful cape]

alrihgt

i change it but it still doenst seem to do it

i could be wrong and my english issnt really good so that might be the problem, not understanding it but here is the code now

high_score = 200
with open("highscore.txt", "w") as file:
    file.write(str(high_score))

with open("highscore.txt", "r") as file:
    high_score = int(file.read())

[dawn quiver]

Wait a sec I'll @ you in another channel, a help channel

#help-mushroom so we don't spam this channel any more lol

[blissful cape]

alright :)

[abstract light]

Has anyone ever used the Tile map software TILED and implemented it in pygame?

[dawn quiver]

May I get some help understanding this code?

dis = pygame.display.set_mode((dis_width, dis_height))
def Your_score(score):
  value = score_font.render("Your Score: " + str(score), True, yellow)
  dis.blit(value, [0, 0])

I'm having a hard time how set_mode can pass the parameter blit, and then value and [0,0]
I checked the documentation and didn't find anything of blit in the set_mode

[proper peak]

presumably set_mode returns a display

pygame.display.set_mode()
Initialize a window or screen for display
set_mode(size=(0, 0), flags=0, depth=0, display=0, vsync=0) -> Surface
yup, returns a Surface.

and Surfaces have .blit:
https://www.pygame.org/docs/ref/surface.html#pygame.Surface.blit

[dawn quiver]

Oh I see

Thanks

Didn't I answer you a few days ago. Do you have more questions about it?

You should try to be more specific with your question. What is your actual question?

[unreal river]

Can someone help me how to make a load bar in pygame?

And also how do you collide the player with platforms?

[brittle nacelle]

is it worth developing games with a pi 4?

[unreal river]

I want some graphics to the load bar :v

[brittle nacelle]

give it an x position and increment it or use images in an array

[unreal river]

I want the load bar to be animated and moving like the installer but thx it give me an idea xD

[brittle nacelle]

loadbar += 1 or you can use animation frames lots of ways 🙂

anyone here who is able to help me with object movement up and down?

[merry ravine]

Pygame library

I am trying to make test_rect change color when player_rect collides
Code

    player_pos = [50, 50]
    player_rect = py.Rect(player_pos[0], player_pos[1], player_image.get_width(), player_image.get_height())
    test_rect = py.Rect(100, 100, 100, 100)
    # this is the collide check
    if player_rect.colliderect(test_rect):
        py.draw.rect(screen, (200, 0, 0), test_rect)
        print("Player collided with test rect")
    else:
        py.draw.rect(screen, (0, 0, 200), test_rect)

under the else statment, if I change the colors it works, as in the rect changes its color to what ever I set it to, but it doesn't change when i collide with it in game

Just follow this pong tutorial and most of your questions will be answered (assuming you are using pygame).

[dawn quiver]

Hello, does someone made following camera in pygame?

[restive lantern]

In order to do that you need to play with the surfaces

[dawn quiver]

you mean if character x+10, then other objects x-10?

[restive lantern]

No

Have you used surfaces in pygame?

[dawn quiver]

Oh surface is a method? never used it before

[restive lantern]

Surface are objects in pygame

[dawn quiver]

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

[restive lantern]

Make a surface where you draw everything then make a rectangle that follows the player and then make a subsurface of that rectangle and then blit that subsurface to the screen

[dawn quiver]

I dont get it sorry, win = pygame.display.set_mode((WIDTH,HEIGHT)) this is my main surface where i have everything drawn yes?

[restive lantern]

Well you have to make a diferent surface to blit all the sprites then you blit the subsurface into the window main surface

Just change everything from the main surface to another new surface

[open epoch]

Anyone know of any games made using Kivy?

[dawn quiver]

to be sure if my map image is 6000x3000, and I'll do it, then I will see other piece of my map than in first "shoot"?

[open epoch]

I have seen the ones on the gallery of their website, but I want to find out if there is anything else.

[restive lantern]

Yea kind of

You dont want to draw the game objects into the main screen what you want in the main screen is the image of a rectangle that follow the character

But if you are not blitting the game objects in the main surface then you have to draw them somewhere else

That means they have to be in a diferente surface

[dawn quiver]

okey, I will try it, thank you! 🙂

hi guys

can i upload a .py file through google play store?

[proper peak]

in short, no

[dawn zinc]

how can i make a game and put it in google play

please i beg you

i am stuck

a 2d one

similar to chess

[proper peak]

you'd have to use a framework for developing android apps in Python - there are a few, like Beeware or Kivy.

The way they work, though, is essentially by translating Python code to Java through a few intermediate representations. No idea how much pain it is working with it.

See, say,
https://stackoverflow.com/questions/49955489/how-to-develop-android-app-completely-using-python

[dawn zinc]

it is compatible with pycharm?

btw+

thanks alot man

god bless you

[open epoch]

Kivy

[proper peak]

no idea if pycharm has special integration with kivy, but not sure what you mean by it being compatible - at worst, you'd have to run the conversion manually from console

[open epoch]

We have used it before. I was actually looking for projects to check out

looking online it seems some people have integrated Pycharm and Kivy

[dawn zinc]

thanks bro

ill check them both

[open epoch]

It seems to be a matter of setting up a project and installing all the pip

[dawn zinc]

have hearb about kivy alot

sometimes its overwhelming to me as a 16 year old guy

its like, i have a question

i get the answer

and i get like another 10 questions

[oblique aspen]

Hey guys

I am love using Python but I don't know if I should use it for game development (I want to do 2d). I know PyGame and I've played around with it before, but I'm on the fence. I also know C# and I am thinking about using a game engine

Is it a good idea?

[proper peak]

Note that if you plan to develop anything even mildly serious, you'll probably want a framework other than pygame - pygame does rendering on the CPU, only, without touching your GPU at all.

so it's pretty good for learning game development, not so much if you want to not drop to 5 fps the moment you start having a bunch of effects

[unreal river]

Yes sorry for late reply

[normal silo]

Do you actually need a load bar? Are spending a lot of time loading?

[gusty wave]

does anyone know how to make a fps counter? like it will show the fps on the title

[unreal river]

Yes

[normal silo]

Are you loading in the main loop?

[unreal river]

YES I know pygame alot :v

[gusty wave]

I was planning on doing this

set_caption("Ree Game " + "FPS - " fps)

but I dont know how to store the fps in a variable

[normal silo]

Do you know how to get a delta time (in seconds)?

[unreal river]

YES

[normal silo]

ok so what are you struggling with?

[unreal river]

Like the animation of the load bar while moving the bar

[gusty wave]

so uh, does anyone know how to get fps?

[unreal river]

wait

[gusty wave]

k

[normal silo]

When loading, you have the current percentage done and the previous percentage done. You can draw the length of the loading bar based on these percentages.

[gusty wave]

are you talking to me?

[normal silo]

no, to Omar

[gusty wave]

ok

[unreal river]

do ```py
fps = clock.get_fps()

[gusty wave]

ok

ty

[unreal river]

@normal silo ty

[normal silo]

Can you get the current percentile and the previous percentile?

[unreal river]

wdym

[normal silo]

Like prev_percentage = 10/ 18, current_percentage = 11 / 18, if you are loading say 18 items.

Basically the progress as a value between 0 and 1.

[unreal river]

I know how to make a health bar is that like that?

[normal silo]

Yes

[unreal river]

Oh.

[normal silo]

The rectangle width is based on the percentage * max_width

[unreal river]

ok

[normal silo]

So if percentage is 100% (full, so 1), then the bar will be max_width long.

[unreal river]

did you define clock?

[gusty wave]

wait

I think it is time

[normal silo]

If it's 0% (empty, so 0), then the bar will be not visible.

[gusty wave]

wait

[unreal river]

ty i get it

[gusty wave]

I think I fixed it

[unreal river]

clock = pygame.time.Clock()

[gusty wave]

yes

thats what I did

[unreal river]

print(fps)

see what you get

[unreal river]

is that in the while loop?

[gusty wave]

no

it is in a def

[unreal river]

call the function to the while loop :v

so the title can update

[gusty wave]

doesn't seem to help

wait

it says there is an error

[unreal river]

can you send me the code?

[gusty wave]

well part of it

 while True:

    glRotatef(25, 2, 1, 0)

[unreal river]

ah

i gotit

the ```py
fps = clock.get_fps()

is got to be in the while loop

[gusty wave]

ok

[unreal river]

are you using clock.tick(fps)?

[gusty wave]

no

[unreal river]

convert the fps to int

[gusty wave]

wdym

[unreal river]

pygame.display.set_caption(str(int(fps)))

make the fps integer so it doesn't show the decimal and make it a string

[gusty wave]

ok

[unreal river]

no

wait

[gusty wave]

1 slight issue

[unreal river]

what

[gusty wave]

it doesn't update

lemme send a gif of it

XD

[unreal river]

wait

bruh the set_caption is in the for event in pygame.event.get()

[gusty wave]

??????

[unreal river]

fix your indentation

[gusty wave]

?

pygame.display.set_caption("Rusted Engine - " + "FPS - " + str(int(fps)))

thats the current one

yikes

[unreal river]

hmm

my way is that to show the fps in the screen

[gusty wave]

nahh

I rather use the title

[unreal river]

xD

[gusty wave]

maybe I should uh pre asset the fps

wait

hmm

[unreal river]

pygame.display.set_caption("Rusted Engine - " + "FPS - " + str(int(fps)))
pygame.display.set_caption(f"Rusted Engine - Fps - {int(fps)}")
```try

[gusty wave]

doesn't pygame have unlimited fps?

ok

dont work

[unreal river]

pygame have unlimited i think

[gusty wave]

hmm

maybe

[unreal river]

try to ```py
clock.tick(60)

[gusty wave]

ahahahhah

still 0

[unreal river]

kkk

[gusty wave]

but it do be running like a champ

smooth

[unreal river]

wait let me get the type

<class 'str'>

it should work :v

[gusty wave]

where in the world should I put

[unreal river]

try to print the fps

[gusty wave]

ok

[unreal river]

it's still 0?

[gusty wave]

it just spams 0.0

clock.tick(60)
print(fps)

[unreal river]

clock = pygame.time.Clock()

while True:
  print(clock.get_fps())
```is this what's in your code?

[gusty wave]

no

the clock.tikck and print is at the end

of the for loop

WHOA

it works

[unreal river]

do the ```py
clock.get_fps()

[gusty wave]

amazing

[unreal river]

xD

LOL

[gusty wave]

ty

[unreal river]

np

[gusty wave]

bruh

it works for printing

but not title

[unreal river]

?

[gusty wave]

now this is just confusing

[unreal river]

kkk

[gusty wave]

pygame logic "It will work with printing"

[unreal river]

when i set the caption in the while loop it works :v

[gusty wave]

I will try something

fps = clock.get_fps()
pygame.display.set_caption("Rusted Engine - " + "FPS - " + str(int(fps)))

wow

thats all I had to do

I feel salty now

I found out by leaving clock.tick empty

it gives me unlimited frames

how nice

[unreal river]

xD

[cyan canopy]

How do I make it so the image moves when I press keys?

[tiny notch]

Have you created a function or variable for pressing keys on the keyboard?

[dawn quiver]

@cyan canopy
you just create a variable that records the coordinates of the image when you first draw it on the screen. lets assume you wish to move the image towards the left or right depending on which arrow keys you press.
Now, when you record events,

`#(in the main game loop)
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
image_x += 10
elif event.key == pygame.K_LEFT:
image_x -= 10

now call the function to draw the image

example: pygame.surface.blit(image, image_x, image_y .. .. .. )

`

so that the image gets blit onto the screen at the image_x and image_y coordinates.

and do remember to call pygame.display.flip() to refresh the display and draw the image with the new coordinates (more like screen refresh)!

similarly if you want the image to go up or down, you simply record the image_y coordinate and just increment it or decrement it depending on where you want to image to go, up or down!

@cyan canopy

[dawn quiver]

maybe try mentioning the full path of the image, like C:/Users/Username/--/EarthCharacter.png
That should help @rocky terrace

[teal ember]

what should i do for smooth keyboard response? like when the user presses the right arrow key and then immediately presses the next, my current program cant respond to the next key, i am doing this in the game loop- py for event in pygame.event.get(): if event.type == QUIT: running = False if event.type == KEYDOWN: alien.moving = True key_direcs = {K_DOWN: "v", K_UP: "^", K_RIGHT: ">", K_LEFT: "<"} if c := key_direcs.get(event.key): alien.direction = c else: alien.moving = False if event.type == KEYUP: alien.moving = False

all the updates are done based upon if the alien object's moving attribute is True or not

hm maybe i should make self.moving a dict for every four directions

so that it doesnt stop moving on the keyup of some other key

welp now i am getting other bugs and it still isnt that smooth

[unreal river]

you can try thispy keys = pygame.key.get_pressed() if keys[pygame.K_UP]: pass or```py
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP:
pass

[teal ember]

ooh i see

nice thanks

[unreal river]

np

@teal ember wait use the first method ```py
keys = pygame.key.get_pressed()
if keys[pygame.K_UP]:
pass

[teal ember]

alright

[teal ember]

hooray it works smoothly now

hmm another thing, how do i slower the rate of updating for my sprite? like, if i lower the fps then everything else becomes slow, and currently the sprite has 3 frames for each step, but when i move the steps update too fast

i want to update the step once per move

idk how to explain properly

[last moon]

ok so I probably overdid it but I had the keydown/keyup signals put into a queue and updated my player based on however many signals there were active

[teal ember]

oh

currently i just used .get_pressed and a single bool attr which determines if the sprite is moving or not

and it works fairly well

https://paste.pythondiscord.com/aciyimedix.py

[last moon]

q = queue.Queue()
if keydown:
  q.put(event_dict.get(key), True)
elif keyup:
  q.put(event_dict.get(key), False)

class Controller: 
  move_dict = {"up": False, "down": False, "left": False, "right": False}
  smoves = {"up": (0, 1)...}
  
  def update():
    while not q.empty:
      key, value = q.get()
      self.move_dict[key] = value
    
    for move, value in self.move_dict.items():
      if value:
        pos += self.smoves[move]```

[teal ember]

[last moon]

it'd be better if it was handled on a separate thread but idk how to do that

also probably unnecessary

[teal ember]

hmm so these are the problems i currently have, first, the sprite has a green bg even though the spritesheet is transparent, and second i want the movements to be a bit slower

like the arms and legs move too fast, dont know how do i slower that individually and not the whole fps

[fervent rose]

Is it fully transparent?

[teal ember]

yes

[fervent rose]

Weird

[last moon]

id say use dt and decrement a 'timer' but idk how you'd do that with pygame

[teal ember]

hmm

[last moon]

async timer maybe?

[teal ember]

gonna stick with this movement for now i guess

but how do i fix that green bg

[snow glacier]

Try

threading.Timer(<ms>, <function>, <*args>)

[last moon]

im familiar with the function yes

but is there a way to do it without comparing the time it takes to draw yourself?

[snow glacier]

elaborate on (the time it takes to draw yourself?)

[last moon]

current_time = time.time()
if current_time - past_time - dt <= time_to_wait:
  draw()
else:
  dt -= current_time - past_time
  past_time = current_time```

smthing like that

a timer

[snow glacier]

So no comparisons

import time

tvec = time.time()
enlapsed = 0
while enlapsed < 1:
  enlapsed = time.time()-tvec

like this

ok

[last moon]

no? that would block the app

[snow glacier]

yes

it would

it can be put on a thread

[last moon]

or asyncio.sleep??

that's what I meant by an async timer?

[snow glacier]

why would you not want to do the comparison?

its a very cheap computation

[last moon]

this one?

[snow glacier]

time.sleep() is inaccurate

in all cases when the deltatime < 0.001

or lower

its system dependant

[narrow kestrel]

cant we make games in tkinter ?

what is special in pygame

it does not even provide 3d view

[snow glacier]

import threading

class Invoke(threading.Thread):
    def __init__(self, dt, function, args: tuple):
        threading.Thread.__init__(self)        
        self.alive = True        

        self.dt = dt
        self.function = function
        self.args = args
        
        self.start()
    
    def run(self) -> None:
        mon = time.time()

        while time.time()-mon <= self.dt:
            pass
        
        self.function(*self.args)

@last moon

[snow glacier]

no!

not cool ones

[snow glacier]

yes it does pygame supports Py OpenGL

tkinter has 0 support for 3D

its even bad for 2D
