Python趣味挑战之教你用pygame画进度条

import pygamepygame.init()screen = pygame.display.set_mode((500,300))pygame.display.set_caption('好看的进度条显示V1.0')clock = pygame.time.Clock()while True: for event in pygame.event.get():if event.type == pygame.QUIT or event.type == pygame.K_F1: pygame.quit() sys.exit() screen.fill((255,255,255)) clock.tick(30) pygame.display.flip()

（一）核心代码

pygame.draw.rect(screen,(192,192,192),(5,100,490,20)) pygame.draw.rect(screen,(0,0,255),(5,100,step,20))

（二）设置步长，并循环递增

step += 1

（三）完整代码

import pygame,syspygame.init()screen = pygame.display.set_mode((500,300))pygame.display.set_caption('好看的进度条显示V1.0')clock = pygame.time.Clock()step = 0while True: for event in pygame.event.get():if event.type == pygame.QUIT or event.type == pygame.K_F1: pygame.quit() sys.exit() screen.fill((255,255,255)) # screen.fill((0,0,0)) pygame.draw.rect(screen,(192,192,192),(5,100,490,20)) pygame.draw.rect(screen,(0,0,255),(5,100,step % 490,20)) step += 1 clock.tick(60) pygame.display.flip()

（四）运行效果

（一）核心代码

pygame.draw.rect(screen,(192,192,192),(5,100,490,20)) pygame.draw.rect(screen,(0,0,255),(5,100,step % 490,20)) font1 = pygame.font.Font(r’C:WindowsFontssimsun.ttc’, 16) text1 = font1.render(’%s %%’ % str(int((step % 490)/490*100)), True, (255,0,0)) screen.blit(text1, (245, 100))

（二）完整代码

import pygame,syspygame.init()screen = pygame.display.set_mode((500,300))pygame.display.set_caption('好看的进度条显示V1.0')clock = pygame.time.Clock()step = 0while True: for event in pygame.event.get():if event.type == pygame.QUIT or event.type == pygame.K_F1: pygame.quit() sys.exit() screen.fill((255,255,255)) # screen.fill((0,0,0)) pygame.draw.rect(screen,(192,192,192),(5,100,490,20)) pygame.draw.rect(screen,(0,0,255),(5,100,step % 490,20)) font1 = pygame.font.Font(r’C:WindowsFontssimsun.ttc’, 16) text1 = font1.render(’%s %%’ % str(int((step % 490)/490*100)), True, (255,0,0)) screen.blit(text1, (245, 100)) step += 1 clock.tick(60) pygame.display.flip()

（三）运行结果

（一）核心代码

pygame.draw.rect(screen,(192,192,192),(5,100,length+10,20)) pygame.draw.rect(screen,(0,0,255),(5,100,step % length,20)) pygame.draw.circle(screen,(0,0,255),(step % length,110),10) font1 = pygame.font.Font(r’C:WindowsFontssimsun.ttc’, 16) text1 = font1.render(’%s %%’ % str(int((step % length)/length*100)), True, (255,0,0)) screen.blit(text1, (245, 100))

（二）完整代码

import pygame,syspygame.init()screen = pygame.display.set_mode((500,300))pygame.display.set_caption('好看的进度条显示V1.0')clock = pygame.time.Clock()step = 0length = 480while True: for event in pygame.event.get():if event.type == pygame.QUIT or event.type == pygame.K_F1: pygame.quit() sys.exit() screen.fill((255,255,255)) # screen.fill((0,0,0)) pygame.draw.rect(screen,(192,192,192),(5,100,length+10,20)) pygame.draw.rect(screen,(0,0,255),(5,100,step % length,20)) pygame.draw.circle(screen,(0,0,255),(step % length,110),10) font1 = pygame.font.Font(r’C:WindowsFontssimsun.ttc’, 16) text1 = font1.render(’%s %%’ % str(int((step % length)/length*100)), True, (255,0,0)) screen.blit(text1, (245, 100)) step += 1 clock.tick(60) pygame.display.flip()

（三）运行效果

（一）加载图片资源

picture = pygame.transform.scale(pygame.image.load(’score/5.png’), (20, 20))

（二）画进度条

pygame.draw.rect(screen,(192,192,192),(5,100,length+10,20)) pygame.draw.rect(screen,(251,174,63),(5,100,step % length,20))

（三）画图片资源

screen.blit(picture,(step%length,100))

（四）画文字

font1 = pygame.font.Font(r’C:WindowsFontssimsun.ttc’, 16) text1 = font1.render(’%s %%’ % str(int((step % length)/length*100)), True, (255,0,0)) screen.blit(text1, (245, 100))
