Foreword: We have learned a lot of knowledge points in the previous lessons, welcome everyone to go to the archeology
Today we will learn to load music and make a music player. The interface functions include:
- Load background cover
- previous song
- start\pause
- next song
- replay
- Shuffle Playback
- fast forward
Effect display (GIF so you can’t hear the sound)
Analysis
pygame.mixer.music.load(song) # load music
pygame.mixer.music.set_volume(0.5) # Set the volume of the player, parameters: 0-1, remember to write smaller, so as not to sound too loud
'''
The first parameter 1 means to play once, 0 means to play in a loop
time: refers to the number of milliseconds from which to start playing
pygame.mixer.music.play(1, time)
'''
pygame.mixer.music.play() # play
pygame.mixer.music.pause()
pygame.mixer.music.unpause()

Shuffle
- randon.randint(number of music)
Precautions and solutions
-
1, start at the same position as the icon of the tentative button, set the variable to switch back and forth
-
2. The first song is currently playing, click the previous one to switch to the last song; play to the last song, click the next one, it should switch to the first song
-
3. Every time a music is played, it should automatically jump to the next one
