Python趣味挑战之教你用pygame画进度条
作者：dhjabc_1
pygame四种方法教会你画进度条,其实也不难,文中有非常详细的代码示例,对正在学习python的小伙伴们很有帮助,需要的朋友可以参考下
一、初始化主界面
import pygame
pygame.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()
二、第一种进度条
（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,sys
pygame.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 = 0
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))
# 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
三、第二种进度条
（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:\Windows\Fonts\simsun.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,sys
pygame.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 = 0
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))
# 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:\Windows\Fonts\simsun.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
四、第三种进度条
（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:\Windows\Fonts\simsun.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,sys
pygame.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 = 0
length = 480
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))
# 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:\Windows\Fonts\simsun.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
五、第四种进度条
（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:\Windows\Fonts\simsun.ttc', 16)
text1 = font1.render('%s %%' % str(int((step % length)/length*100)), True, (255,0,0))
screen.blit(text1, (245, 100))
（五）完整代码
import pygame,sys
pygame.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()
picture = pygame.transform.scale(pygame.image.load('score/5.png'), (20, 20))
step = 0
length = 480
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))
# screen.fill((0,0,0))
pygame.draw.rect(screen,(192,192,192),(5,100,length+10,20))
pygame.draw.rect(screen,(251,174,63),(5,100,step % length,20))
screen.blit(picture,(step%length,100))
font1 = pygame.font.Font(r'C:\Windows\Fonts\simsun.ttc', 16)
text1 = font1.render('%s %%' % str(int((step % length)/length*100)), True, (255,0,0))

OK，写完，本博文纯属科普贴，技术含量不高，入门级别，大家喜欢就好。
而且里面代码相对比较简单，也没有考虑优化，大家在实操过程中可以优化完善，并反馈给我一起进步。
