I gave diordnas proposal a spin, and ran into some strange errors.
When taking a closer look at the code, I realized that I did not
understand what (s)he was doing.
So I adjusted the skeletton to my level of python skills and even got
it to work (in a 2 second test..)
Here it goes:
import pyglet.clock, time
class GameClock(pyglet.clock.Clock):
def __init__(self):
self.dt = 0.0
self.paused = False
self.pause_start = 0
self.total_pause_time = 0
super(GameClock, self).__init__(time_function=self.game_time)
pyglet.clock.set_default(self)
def tick(self,poll=False):
self.dt = super(GameClock,self).tick(poll)
if self.paused: self.total_pause_time += self.dt
def game_time(self):
if self.paused:
return self.pause_start
else:
return time.time() - self.total_pause_time
def pause(self):
if not self.paused:
self.pause_start = time.time()
self.toggle_pause()
def unpause(self):
if self.paused:
self.toggle_pause()
def toggle_pause(self):
self.paused = not self.paused
I do not know if one approach is better. what is a drawback of mine is
that I store the total pause time and substract it every time I return
the current time. So if there are long periods of pause, a high number
has to be substracted each frame when the game runs again. The game
"stays" in the past so to speak. I can't think of any other way to do
it atm, but this may be because of my bad design with scheduling
callbacks.
Cheers
