Re: Pyglet culling destroys FPS

Adding/removing for ordering is unnecessary, you just need to enable depth testing and change the relevant textures z coordinates (between 1.0 to 0.0):

import pyglet
from pyglet.gl import *

class group(pyglet.graphics.OrderedGroup):
   
def set_state(self):
       
if self.order == 0:
            glBindTexture
(GL_TEXTURE_2D, texture.id)
       
elif self.order == 1:
            glBindTexture
(GL_TEXTURE_2D, texture2.id)

window
= pyglet.window.Window(640,480)

glEnable
(GL_DEPTH_TEST)

rendered_sprites
= []

batch
= pyglet.graphics.Batch()

batch_idle
= pyglet.graphics.Batch()

texture
= pyglet.image.load('test.png').get_texture()

texture2
= pyglet.image.load('test2.png').get_texture()

rendered_sprites
.append(batch.add(4, GL_QUADS, group(0),
                                 
('v3f/static', (0.0,0.0,0.0, 32.0,0.0,0.0, 32.0,32.0,0.0, 0.0,32.0,0.0)),
                                 
('t3f/static', texture.tex_coords)))

rendered_sprites
.append(batch.add(4, GL_QUADS, group(1),
                                 
('v3f/static', (16.0,0.0,0.0, 48.0,0.0,0.0, 48.0,32.0,0.0, 16.0,32.0,0.0)),
                                 
('t3f/static', texture2.tex_coords)))


<at> window.event
def on_draw():
    window
.clear()
    glEnable
(GL_TEXTURE_2D)
    batch
.draw()
    glDisable
(GL_TEXTURE_2D)

<at> window.event
def on_key_press(symbol,modifiers):
   
if symbol == pyglet.window.key.SPACE:
       
if rendered_sprites[1].vertices[2] == 0.0:
           
for a in xrange(2,12,3):
                rendered_sprites
[1].vertices[a] = 1.0
       
else:
           
for a in xrange(2,12,3):
                rendered_sprites
[1].vertices[a] = 0.0

pyglet
.app.run()

Pyglet also has multi-texturing support, if your inclined to use multiple textures per surface.

Pyglet culling destroys FPS

I searched previously and found a thread on culling off screen sprites for better performance. In the end, the guy suggested to simply set a sprites visible flag.

However, I have tried this and the performance is abysmal, making the game unplayable.

Here is my code:

class TileLayer(object):
   
def __init__(self):
       
self.group = pyglet.graphics.Group()
       
self.batch = pyglet.graphics.Batch()
       
self.sprites = []
       
self.cache = {}
       
   
def setInViewSprites(self):
       
""" Called everytime the camera bounds change, cache which sprites are in view and not in view, then change visibility """
        bounds
= viewService.getScreenBounds()

       
if not bounds in self.cache:
            inViewSprites
= []

           
for sprite in viewService.collideView(self.sprites):
                inViewSprites
.append(sprite)
           
           
self.cache[bounds] = inViewSprites

       
for sprite in self.sprites:
           
if not sprite in self.cache[bounds]:
               
if sprite.visible == True:
                    sprite
.visible = False
           
else:
               
if sprite.visible == False:
                    sprite
.visible = True


This seems super inefficient to me, but I can't think of any other way. In another library I could simply just keep a list of sprites in and out of view, and pass the list to the renderer for easy and quick removal of sprites.

However because of batching and groups, this doesn't seem possible. Any suggestions?

audio crah (Pulseaudio)

Hello,

I am running Ubuntu 14.04

I unstalled the pygame-pyglet package which had a version dated from 2009 an ran 'pip install pyglet' to install a more up to date version of pyglet.

Now, the attached python script crashes when playing audio (while it worked with the 2009 version of pyglet)

Below is the console's output (with debug_media set to True):

I do not know if it is the origin of the probleme but I noticed the odd message "Error importing driver directsound: 'module' object has no attribute 'oledll'" (as I am running under linux).

Re: Wacom usage on osx

I don't know what Pyglet's support for tablets is like at the moment, but Wacom provides excellent documentation as to accessing tablet events on Mac:

http://www.wacomeng.com/mac/Developers%20Guide.htm

At this point I don't honk any mucking around in Carbon or HID is required. The standard Cocoa NSEvent object carries everything you need, which should make it easy to expose to pyglet.

Texture bleedthrough issues

I have been testing my game in just one resolution for quite a while.

Today I decided to change the resolution to something bigger to test out and to support more resolutions and see how they behave. I began to notice that tons of textures are bleeding through my tileset and animated textures. Sometimes they disappear if I zoom in, or move the character, sometimes they bleed on different sides, and sometimes the bleed disappears entirely. 

I have googled a ton on this but can't find any resolution. So I have checked the following:
Mipmap issue: Not using mipmapping
Issue with filtering: Changed pyglet to use GL_NEAREST not GL_LINEAR for textures. Not using AA or other sampling.
Texture coordinates are incorrect: I am assuming pyglet's are correct as I have not changed this.
Set clamping: Tried setting clamping in all of the places that set the min/mag_filter.
Camera is sampling floats: I've made sure to force camera movement in 1 pixel increments to make sure it doesn't get in-between a pixel.

I have checked all of these and the issue still remains. What am I missing?

AVbin v5 64bit for windows

Hi!

I'm looking for the 64-bit version of Avbin 5 dll, but could not find it on the webpage. I need it for a codebase that relies on pyglet 1.1.4 where the python environment upgraded from 32 to 64-bit under win7. Tried pyglet 1.2.4 with Avbin 10, but it crashed the application.

Thanks,
RedDevil91

pyglet 1.2.4 crashes with RuntimeError

Hi!

I have the following issue.
After upgrading my toolchain from 32 bit to 64 bit I upgraded pyglet 1.1.4 to pyglet 1.2.4. After all my program (which uses pyglet video player) crashes with the following error

Caught exception in background:

and stays in a forever loop. I tried to figure out what can cause the problem but I failed. My program remained the same only pyglet (and other modules) was upgraded.
I am working on a 64bit windows computer with 64bit python and pyglet uses avbin v8 64bit.
Can somebody tell me what causes the problem and why?

Documentation is incomplete

Hey, everybody. A while ago I was reading the documentation, I believe I was reading a section on Pyglet's event framework, and it was incomplete compared to what we used to have. I don't remember what section it was, but I noticed, again, that the documentation is incomplete. I noticed that I can still access the old documentation, however.

If you compare:
http://pyglet.readthedocs.org/en/latest/api/pyglet/window/pyglet.window.Window.html

with:
http://pyglet.readthedocs.org/en/pyglet-1.2-maintenance/api/pyglet/window/pyglet.window.Window.html

The latter is, honestly, far better than the prior. Maybe someone can give it a look-over?

some precisions about pyglet release plans?

Hello, on behalf of cocos library I want to ask

1. Will the <at> property refactor in pyglet default keep out of the 1.2.x releases ?
2. Can we have a ballpark date when that refactor will land in a release to pypi ?

This is so in cocos library we can plan when to switch pyglet supported version

thanks
