Re: how would you pause game?

[Winston Wolff]

I don't know off the top of my head but I know that cocos2d ( http://cocos2d.org ) implements pause, and it uses Pyglet. You could investigate that.

You can use something like this:

class AdjustableClock(pyglet.clock.Clock):
__time = 0
speed = 1

def __init__(self):
pyglet.clock.Clock.__init__(self, time_function=self.get_time)
pyglet.clock.schedule(self.advance)

def advance(self, time):
self.__time += time * self.speed

def get_time(self):
return self.__time

..and use an instance of that clock everywhere (except e.g. animations
in the pause menu).
To pause, set the clock's speed to zero.

I've tried to use it, but function scheduling seems to not be working with that custom clock.

Used following code, but while pyglet.clock scheduled events occur, TestClock scheduled ones do not...

What's wrong with it?

import pyglet

class TestClock(pyglet.clock.Clock):
    __time = 0
    speed = 1.0

    def __init__(self):
        pyglet.clock.Clock.__init__(self, time_function=self.get_time)
        pyglet.clock.schedule(self.advance)

    def advance(self, time):
        self.__time += time * self.speed

    def get_time(self):
        return self.__time
   

    def set_speed(self, dt=0, speed=1.0):
        print "Set speed", speed
        self.speed = speed

class A(object):
    def __init__(self):
        self.clk = TestClock()
        self.clk.schedule_interval(self.te, 0.3)
    def te(dt=0.0):
        print "TEST", dt
    def up(self, dt):
        print 'up'
 
window = pyglet.window.Window()
label = pyglet.text.Label('Hello, world',
                          font_name='Times New Roman',
                          font_size=36,
                          x=window.width//2, y=window.height//2,
                          anchor_x='center', anchor_y='center')
@window.event
def on_draw():
    window.clear()
    label.draw()
       
def x():
    print "X"
       
testobj = A()

pyglet.clock.schedule_interval(testobj.up, 1/6.0)
testobj.clk.schedule_once(x, 2)

pyglet.clock.schedule_once(testobj.clk.set_speed, 5, speed=10.0)

pyglet.app.run()

Changed 'advance' function to:

    def advance(self, time):
        self.__time += time * self.speed

        self.tick()

Now works
