Clock reports wrong fps when EventLoop.idle() is overridden
Hello,
I tried fixing my frame rate by overriding EventLoop.idle() method and
dispatching on_draw only in scheduled actions, however ClockDisplay is
now showing nonsense. It behaves as if every clock.tick() is followed
by on_draw event, but this isn't true anymore, so displayed fps is
higher than real fps. This program reproduces bug (if it's not a
feature):
#!/usr/bin/python
import pyglet
window = pyglet.window.Window(vsync = False)
event_loop = pyglet.app.EventLoop()
fps_display = pyglet.clock.ClockDisplay()
@window.event
def on_draw():
window.clear()
fps_display.draw()
def update(dt):
if not window.has_exit:
window.dispatch_event('on_draw')
window.flip()
def idle():
pyglet.clock.tick(True)
return pyglet.clock.get_sleep_time(True)
pyglet.clock.schedule_interval(update, 1.0 / 30.0)
event_loop.idle = idle
event_loop.run()
It looks like problem is in clock.tick() method, it pushes new delta
time into sliding window every time it's called. I haven't tested SVN
version, but after quick look into repository I was unable to spot any
significant changes in there. Am I doing something wrong, or is it
really a bug?
