Body
In my pong game, whenever someone scores (the ball goes out to the left or to the right) the ball position is reset to the middle of screen and it waits one second before moving. In that one second I have a little animation going on. My problem is this: if I pause the game in the middle of the animation, even though none of the objects are updated and only the pause text is drawn, time keeps rolling in. And if I wait time enough, the animation just stops right after I unpause the game. Here's what I mean. This is the ball update: <pre><code>def update(self, dt): now = pygame.time.get_ticks() / 1000 # if time elapsed since the ball got out >= BALL_WAIT_TIME if now - self._spawn_time >= BALL_WAIT_TIME: self.rect = self.calcnewpos(dt) self.handle_collision() # spawn animation else: step = 255 / (FPS * BALL_WAIT_TIME) value = int(self._frame * step) rgb = (value, value, value) self._draw_ball(rgb) self._frame += 1 </code></pre> From <a href="http://pygame.org/docs/ref/time.html#pygame.time.get_ticks" rel="nofollow">http://pygame.org/docs/ref/time.html#pygame.time.get_ticks</a>: <blockquote> pygame.time.get_ticks() Return the number of millisconds since pygame.init() was called. Before pygame is initialized this will always be 0. </blockquote> So even though nothing is drawn or updated while the game is paused, pygame.time.get_ticks() will still return the time elapsed since <code>pygame.init</code>. How can I solve this? Sorry if that is a little hard to understand, I'll post the rest of the code if needed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
