kandi X-RAY | pyglet Summary
pyglet is a cross-platform windowing and multimedia library for Python, intended for developing games and other visually rich applications. It supports windowing, user interface event handling, Joysticks, OpenGL graphics, loading images and videos, and playing sounds and music. pyglet works on Windows, OS X and Linux. NOTE! The pyglet-1.5-maintenance branch is the current stable release. The master branch contains the the development code for the upcoming 2.0 release, and may be unstable. If you want to do a pull request, please target the pyglet-1.5-maintenance branch where appropriate. Pyglet has an active developer and user community.

QUESTION
I'm just trying to make a game like minecraft, but I just can't add to a vbo from another process. The strange thing is that the logs appear two times and the window just closes instantly.
The code ...ANSWER
Answered 2022-Feb-15 at 21:21The OpenGL Context is thread local. If you want to use an OpenGL context in another thread, you must make it the current context there.
The context can only be current in one thread at a time. When the context for a thread becomes current, it is exclusive to that thread and is claimed, so it is automatically not the current context for all other threads. If you want to use the same context in multiple threads, you must lock the sections that use the context to ensure exclusive access to the context. Most likely this is not what you want.
If you want to use the buffer for drawing in one thread, but at the same time you want to change its content in another thread, you need 2 OpenGL contexts, where the first context shares the second context.
There are some more problems with your code:
- Thie size of the buffer date needs to be specified in bytes. Therfore the size of the data is 12*4 instead of 12. See
glBufferData. - The vertex attribute specification is a state of the context that is not shared. An object is tied to the context. So when the context is destroyed, the object is destroyed. See OpenGL Context.
- See Minimal Windowless OpenGL Context Initialization, Windowless OpenGL, OpenGL render view without a visible window in python
An OpenGL context depends on the OpenGL window. So you need to create a hidden OpenGL window to get a second OpenGL context with a correct version. I don't think this is even possible with pygame (Pygame 2 is based on [SDL2], there might be a solution for that).
A basic setup using GLFW looks as follows. The vertex buffer object is created on the main thread. In the 2nd thread, a hidden OpenGL window is created that shares the context of the main thread. In this Context the buffer object's data store is updated with glBufferSubData:

QUESTION
So after getting inspired by code bullet to try out pyglet. Recently I have been creating many small games and simulations with it. The current one being a game is a flappy bird(Pretty sure you've all played that). So my mission is to code flappybird with pyglet today. But as usual, I fell into a problem, and even though there were many questions and answers for this problem as I was using pyglet all of the other answers weren't working. The code I have written for the flappy bird is pretty straightforward. I have 2 classes the bird and the pipe and I render all of them using batches and groups. here:

I am trying to use a stencil test to clip and create borders for 2d content, but it does not seem to work. It might be a platform issue, I am running the code on a M1 MacBook Air with MacOS 12.0.1
From the code below I would expect a blue square with a 50px red border, I get only a big red square.

Answered 2022-Jan-01 at 16:39The window does not have a stencil buffer. There is no guarantee that the window's default framebuffer will have a stencil buffer by default. Explicitly specify the stencil buffer bits (see pyglet, Context configuration):

QUESTION
It is not much information out there how to do a 2d camera in Pyglet. I assume its not a good idea to move all sprites so I look for something similar to a Surface in Pygame that I could move instead. But the is no such thing in Pyglet? Is this the way it should be done in openGl? or am I missing something important? I don't know what the gl command do but it is working.
...ANSWER
Answered 2021-Oct-20 at 19:11There is a camera example in the pyglet/examples folder: https://github.com/pyglet/pyglet/blob/pyglet-1.5-maintenance/examples/window/camera.py
QUESTION
I'm making a MediaPlayer using python and pyglet. At the moment I can load any audio file just as intended. However I've run into an issue where pyglet only seems to load files at a speed of 2.4MBps. Now this is fine for 5min songs. However I'd like to be able to use it for audiobooks as well. These can be 10+ hours long and over 500MB in size.
There are two problems with those right now.
- It takes forever to load (windows already marks the window with "No response"). It will load eventually and play just fine, it just takes too long.
- The player itself starts eating up RAM. Loading a 700MB audiobook resulted in the application using almost 5GB of RAM.
Is there a way to fix these problems?
Not sure if my code would help, but these are the lines I assume are most relevant
...ANSWER
Answered 2021-Oct-17 at 20:52I just realised that in my case, I can just set streaming=True and the problems mentioned above seem to be solved.
However it would still be interesting if someone has a fix that actually adresses the problem instead of just circumventing it.
