Pygame is a set of Python program modules used to develop game software, developed on the basis of the SDL library. Allows you to create feature-rich games and multimedia programs in Python programs. Pygame is a highly portable module that can support multiple operating systems.
Development environment: python3.7 + pycharm community edition
One, the installation of pygame
1 Graphical interface installation
Select File---settings in pycharm
2 Command line installation
Execute in terminal:
pip install pygame -i https://pypi.douban.com3 The simplest structure of pygame
Create a new py file and type the code as shown below:
The basic structure of pygame consists of three parts:
- Initialize pygame
- Create game window
- Create a game loop
Second, the realization of the music player
The implemented player is as follows:
The structure of the project:
To implement the player, the following problems must be solved:
- How to realistic pictures
- How to play music
- How to judge whether the mouse has clicked the button
- How to display text
- How to implement a progress bar
1 Picture display
Images are very important resources in the game. Images may be some backgrounds, characters, etc. pygame supports the following image formats: jpeg, png, bmp, gif, etc. Usually to display a picture, there are three steps:
# 显示背景
# 1.加载图片
background = pygame.image.load("images/player.png")
# 2 把图片贴到窗口上
# 参数：要显示的图片对象，在目标窗口的坐标
screen.blit(background,(0,0))
# 3 刷新屏幕
pygame.display.flip() Complete code:
# 导入pygame
import pygame
#rect描述对象位置，参数包括left(x坐标),top(y坐标),width,height
WINDOW = pygame.Rect(0,0,480,380)
def main():
global index
index = 0 # 默认是第一首歌曲的下标
# 1. 初始化pygame的各个模块
pygame.init()
# 2 建立一个游戏窗口
screen = pygame.display.set_mode(WINDOW.size)
# 设置窗口标题
pygame.display.set_caption("音乐播放器")
# 显示背景
background = pygame.image.load("images/player.png") # 加载图片
screen.blit(background,(0,0)) # 把background贴到窗口上
pygame.display.flip() # 刷新屏幕
# 3 建立一个游戏循环
running = True
while running:
# 处理用户的事件
for event in pygame.event.get():
# type事件类型
if event.type == pygame.QUIT:
running = False
if __name__ == '__main__':
main()You can see the interface after running:
2 Play music
To play music, use the mixer module, among which the common methods are:
pygame.mixer.music.load(file) 使用文件名作为参数载入音乐 ,音乐可以是mp3等格式
pygame.mixer.music.play() 播放载入的音乐pygame.mixer.music.stop() 停止播放，
pygame.mixer.music.pause() 暂停播放。pygame.mixer.music.unpause() 取消暂停。
pygame.mixer.music.set_volume(value) 来设置音量，音量value的范围为0.0到1.0。
pygame.mixer.music.get_volume() 获取音量大小。
pygame.mixer.music.get_pos() 获取播放的时长，单位毫秒Because the song to be played is not a song, you can define a global variable to save the song list. Define a function to complete the loading of the song list
song_list = [] # 歌曲列表
# 加载歌曲列表
def load_songs():
songs = os.listdir("music")
songs = ["music/"+song for song in songs]
song_list.extend(songs)
# 播放指定的歌曲
def play(index): # index当前歌曲的索引
pygame.mixer.music.stop()
# 播放音乐
music = pygame.mixer.music.load(song_list[index])
pygame.mixer.music.play()Main function:
def main():
index = 0 # 默认是第一首歌曲的下标
# 1. 初始化pygame的各个模块
pygame.init()
# 2 建立一个游戏窗口
screen = pygame.display.set_mode(WINDOW.size)
# 设置窗口标题
pygame.display.set_caption("音乐播放器")
# 显示背景
background = pygame.image.load("./images/player.png") # 加载图片
screen.blit(background,(0,0)) # 把background贴到窗口上
pygame.display.flip() # 刷新屏幕
# 加载歌曲列表并播放第一首歌曲
load_songs()
play(index)
# 3 建立一个游戏循环
running = True
while running:
# 处理用户的事件
for event in pygame.event.get():
# type事件类型
if event.type == pygame.QUIT:
running = False
Up to now, we can already play music
