Game Speed

In this lesson, you’ll adjust the speed of your game using the pygame module time. Normally, you want as high a frame rate as possible, but for this game, you may need to slow it down a bit for the game to be playable. Fortunately, the module time contains a Clock designed precisely for this purpose.

Using Clock to establish a playable frame rate requires just two lines of code. The first creates a new Clock before the game loop begins:

102 # Setup the clock for a decent framerate
103 clock = pygame.time.Clock()

The second calls .tick() to inform pygame that the program has reached the end of the frame:

179 # Flip everything to the display
180 pygame.display.flip()
181 
182 # Ensure program maintains a rate of 30 frames per second
183 clock.tick(30)

For more information about Clock and .tick(), check out the following resources from the pygame documentation:
