Python arrow keys control up and down code, python arrow keys up and down

The code shown in this article implements the python programming arrow keys to control the image from top to bottom. First, let's take a look at the demo results.

Demo:

Instance code:

bif="1.jpg" mif="2.jpg" import pygame,sys from pygame.locals import *  pygame.init()  screen=pygame.display.set_mode((640,360),0,32) background=pygame.image.load(bif).convert() mouse_c=pygame.image.load(mif).convert_alpha()  x,y=0,0 movex,movey=0,0  while True:   for event in pygame.event.get():     if event.type ==QUIT:       pygame.quit()       sys.exit()     if event.type==KEYDOWN:       if event.key==K_LEFT:         movex=-1       if event.key==K_RIGHT:         movex=+1       elif event.key==K_UP:         movey=-1       elif event.key==K_DOWN:         movey=+1     if event.type==KEYUP:       if event.key==K_LEFT:         movex=0       if event.key==K_RIGHT:         movex=0       elif event.key==K_UP:         movey=0       elif event.key==K_DOWN:         movey=0    x+=movex   y+=movey      screen.blit(background,(0,0))   screen.blit(mouse_c,(x,y))      pygame.display.update() 

Summary

I think the most basic function of game programming is to control the movement of items through the mouse and keyboard, as well as the collision detection of objects.
