This article mainly introduces "how to use Pygame to make simple animation". In daily operation, I believe many people have doubts about how to use Pygame to make simple animation. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubt of "how to use Pygame to make simple animation". Next, please follow the editor to study!

Preface

To achieve a frame animation, the use of a graph, according to different times to display different pictures.

Use a picture as shown below, with a width of 780 * 300, using a loaded image of 260 * 150.

Pygame.init () screen = pygame.display.set_mode ((400,300), 0,32) pygame.display.set_caption ("animation") while True: for event in pygame.event.get (): if event.type = = pygame.QUIT: sys.exit () key = pygame.key.get_pressed () if key [pygame.K _ ESCAPE]: sys.exit () screen.fill ((154,205) ) pygame.display.update ()

First implement the simplest graphics

timer

First of all, change the current image according to the different time.

Time timing is implemented using pygame.time.Clock (). Get_ticks () gets an increasing or decreasing amount of time.

Framerate = pygame.time.Clock () frametate.tick (30) ticks = pygame.time.get_ticks () pygame.init () screen = pygame.display.set_mode ((400,300), 0 32) pygame.display.set_caption ("animation") framerate = pygame.time.Clock () while True: framerate.tick (30) ticks = pygame.time.get_ticks () print (ticks) for event in pygame.event.get (): if event.type = = pygame.QUIT: sys.exit () key = pygame.key.get_pressed () if key [pygame.K _ ESCAPE]: Sys.exit () screen.fill 205,255)) pygame.display.update ()

The output is shown above, 30 frames per second, so the time increases by about 34-33 each time, and as shown above, we get an amount that changes over time.

Draw the wizard

Here the wizard is used to draw the picture for ease of operation.

Pygame.sprite.Group () creates a spirit group, and then draws the corresponding elves using the corresponding update draw
