Python趣味挑战之教你用pygame画进度条

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()

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))

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。
