pygame多种方式实现屏保操作(自动切换、鼠标切换、键盘切换)

pygame多种方式实现屏保操作(自动切换、鼠标切换、键盘切换),欢迎往下观看。

一、图片处理

(一)图片采集

我认为有三种方法:

其一:使用爬虫技术从网上下载图片,可以开一个子线程负责采集网上图片,然后加载到list列表中;
其二:可以直接对电脑中所有的盘进行自动检索,然后加载到list列表中;
其三:指定目录,然后加载到list列表中;
我这里偷个懒,选择第三种方法实现。具体代码如下:

?
1
2
3
4
5
path = './image/'
files = []
dirs = os.listdir(path)
for diretion in dirs:
    files.append(path + diretion)

(二)图片装载

我为什么在初始化的时候就进行装载呢?

原因是:解决效率问题,无需每次使用时重复加载,而且在初始化的时候就适配屏幕大小进行图片缩放。

因此,我把这个过程打包成一个函数,方便后续调用,而且参数传递为:屏幕的大小。然后返回bglist对象。

for file in files:
    picture = pygame.transform.scale(pygame.image.load(file), (1440, 900))
    dSurface = picture
    # dSurface = pygame.image.load(file).convert()
    bglist.append(dSurface)

(三)完整代码

封装成函数:

?

def init_image():
    path = './image/'
    files = []
    dirs = os.listdir(path)
    for diretion in dirs:
        files.append(path + diretion)
 
    for file in files:
        picture = pygame.transform.scale(pygame.image.load(file), (1440, 900))
        dSurface = picture
        # dSurface = pygame.image.load(file).convert()
        bglist.append(dSurface)

二、初始化pygame相关参数

(一)设置初始化参数

?

pygame.init()  # 初始化pygame类
# 设置窗口大小
pygame.display.set_caption('美丽的屏保'# 设置窗口标题
tick = pygame.time.Clock()
fps = 10  # 设置刷新率,数字越大刷新率越高
fcclock = pygame.time.Clock()
bglist = []
flag = 0
runimage = None

(二)设置为全屏显示:

?
1
screen = pygame.display.set_mode((1440, 900),flags=pygame.FULLSCREEN)

三、核心模块

(一)自动切换

def run():
    flag = 0
    runimage = random.choice(bglist)
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()
        screen.fill((255, 255, 255))  # 设置背景为白色
        screen.blit(runimage.convert(), (0, 0))
        if flag % 100 == 1:
            runimage = random.choice(bglist)
        flag += 1
        fcclock.tick(fps)
        pygame.display.flip()  # 刷新窗口

(二)键盘切换

for event in pygame.event.get():
    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_ESCAPE:
            pygame.quit()
            sys.exit()
        if event.key == pygame.K_SPACE:
            reset()

(三)鼠标切换

?
1
2
3
for event in pygame.event.get():
    if event.type == pygame.MOUSEBUTTONDOWN:
        reset()

(四)退出操作

?

4
for event in pygame.event.get():
    if event.type == pygame.QUIT or event.type == pygame.K_F1:
        pygame.quit()
        sys.exit()

(五)设置透明色

?
1
runimage.set_alpha(255-flag*2)

def run():
    global flag,runimage
    runimage = random.choice(bglist)
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT or event.type == pygame.K_F1:
                pygame.quit()
                sys.exit()
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_ESCAPE:
                    pygame.quit()
                    sys.exit()
                if event.key == pygame.K_SPACE:
                    reset()
            if event.type == pygame.MOUSEBUTTONDOWN:
                reset()
        screen.fill((255, 255, 255))  # 设置背景为白色
        screen.blit(runimage, (0, 0))
        if flag % 100 == 1:
            reset()
        flag += 3
        runimage.set_alpha(255-(flag*2) % 250)
        fcclock.tick(fps)
        pygame.display.flip()  # 刷新窗口

四、其他相关函数:

(一)reset函数

?

4
def reset():
    global flag,runimage
    flag = 0
    runimage = random.choice(bglist)

(二)main函数

?
1

3
if __name__ == '__main__':
    init_image()
    run()
