Hello all, I was writing code in a pyglet 1.0-1.1 mixed way, then when
I tried to play sounds I discovered that they loop eternally unless I
use the run() method. However every update I need to assign a value to
a variable I call time, and I can't do that with a standard app loop.
So I customize my app, but now it doesn't even draw anything, and
sounds still loop eternally! Help! What must I do?
Here is the code:

psyco.full()
import pyglet
from pyglet import window
from pyglet.gl import *
from pyglet.window import mouse
from pyglet.window import key
import math
import pyglet.clock
WIDTH = 1024
HEIGHT = 768
VERSION = 'alpha 0.1'
win = window.Window(width=WIDTH,height=HEIGHT,visible=False)
win.set_caption('concert drummer '+VERSION)
dt = 0
kick = [key.Z,key.X]
snare = [key.S,key.D]
hihat = [key.E,key.R]
ride = [key._3,key._4]
crash = [key.T,key.Y]
keys =
{'kick':kick,'snare':snare,'hihat':hihat,'ride':ride,'crash':crash}
kicks = pyglet.media.load('kick.ogg', streaming=False)
sounds = {'kick':kicks}
time = 0
track = []
bpm = 0
quadratic=0
clock=pyglet.clock.Clock()
win.switch_to()
win.set_visible()
drumfile = open('test.ndm','r')
drumfile = drumfile.readlines()
bpm = int(drumfile[0])
drumfile = drumfile[1:len(drumfile)]
drumfile = drumfile[1:len(drumfile)]
for item in drumfile:
toadd = []
for char in item[0:-1]:
if char == '1':
toadd.append(1)
else:
toadd.append(0)
track.append(toadd)
