Hi,

I have tried some shadertoys examples.

It seems the audio input can be the 'output' from the sounds playing in jupylet, but is there a way to use realtime audio input from the soundcard?

Thank you

Hi,

I'd like to run an (headless) App in a separate thread.

I'd like to render some shaders, and use the framebuffer into another part of my application.

I tried this simple code:

#!/usr/bin/python3

import time
from jupylet.app import App

if __name__ == '__main__':

    def create_and_run_app():
        app = App(width=512, height=512, quality=100, fullscreen=False, mode="hidden")  #, log_level=logging.INFO)
        app.start()

    import _thread
    _thread.start_new_thread(create_and_run_app, ())

    time.sleep(10)

but I get this error:

Exception ignored in thread started by: <function create_and_run_app at 0x7f807b0060d0>
Traceback (most recent call last):
  File "p.py", line 9, in create_and_run_app

    raise ValueError('Requested OpenGL version {}, got version {}'.format(
ValueError: Requested OpenGL version 330, got version 0

I also tried to use mode="auto" and app.run(), but I get:

Exception ignored in thread started by: <function create_and_run_app at 0x7f34e3fc30d0>
Traceback (most recent call last):

    raise RuntimeError('There is no current event loop in thread %r.'

Is there a way to call a render iteration x times per second, or in a separate thread?

Thank you

Hi, thanks for this amazing jupylet. Installed and now trying the examples to understand how to use jupylet. On Windows 10, using Python 3.6, I can't close all examples started from IDLE. The same goes for all examples run on jupyter. When I close the jupyter's browser tabs, all jupylet examples are still running. The only way to close the examples are thru Task Managers.

Is there any flag to set so that App.run() can automatically exit / quit when its window / display is closed ? Or maybe "exit/quit event" that needs to be handled ?

Thank you

Hi,

I'm trying to run jupylet on Windows, with Python 3.9.1. After installing the libraries following the instructions on the docs, if I try to run any example that creates an App I am getting the error:

app = App()

Any idea what could be wrong?

Thank you!

Hi,

Is there anything I can do about it?

Hello

I have just tried to integrate jupylet into my script. However I am getting the following error: packages/jupylet/env.py:68: in has_display if 'pyglet' in sys.modules: E NameError: name 'sys' is not defined when simply importing jupylet

It has been fixed for me by simply adding import sys in the head of that file locally.

Could you please fix that on the file?

Thanks!

When I try to test the game in Jupyter (notebook or lab) I can't play the game. When I try to press the up/down keys it responds by moving up or down a cell and when I try left/right it does nothing. It kinda seems like it might be displaying as a just image, I'm not sure.

Is there something I'm missing? Did I miss a step somewhere?

For example, take this code:

#!/usr/bin/python3

import argparse
from jupylet.app import App
# app = App(width=512, height=512)

parser = argparse.ArgumentParser(description='bla')
args = parser.parse_args()

if I run:

$ ./p.py  --help

I get:

usage: p.py [-h]

bla

optional arguments:
  -h, --help  show this help message and exit

as expected.

But if I uncomment the line that instantiates app, I get:

$ ./p.py  --help

usage: p.py [-h] [--window {pyglet,glfw}] [--log_level {DEBUG,INFO,WARNING,ERROR}]

optional arguments:
  -h, --help            show this help message and exit
  --window {pyglet,glfw}
                        Windowing library to use.
  --log_level {DEBUG,INFO,WARNING,ERROR}
                        logging level.

So it makes it hard to import App outside of jupylet

Thanks

For example, suppose you have a file game.py with

from jupylet.label import Label as Label
from jupylet.app import App as App

app = App(width=320, height=64)

sitting next to a notebook in which you have

import game

hello = game.Label('hello, world', color='cyan', font_size=32, x=game.app.width, y=16)

@game.app.run_me_every(1/30)
def scroll(ct, dt):
    hello.x = hello.x - 1

    if hello.right < 0:
        hello.x = app.width
        
@game.app.event
def render(ct, dt):
    game.app.window.clear()
    hello.draw()
    
game.app.run()

This all runs fine. However, if syntax errors are introduced into scroll and render, no error message will appear.

When run as a stand-alone script on Windows 10 (Python 3.7.9), example programs just die silently after the first jupylet import (e.g. from jupylet.sprite import Sprite in spaceship.py)
