Adding background music and sound effects

Remarks#

Try to play music in ‘.wav’ instead of ‘.mp3’.In ‘.mp3’ the music lags.

Example to add music in pygame

import pygame
file = 'some.mp3'
pygame.init()
pygame.mixer.init()
pygame.mixer.music.load(file)
pygame.mixer.music.play(-1) # If the loops is -1 then the music will repeat indefinitely.

Example to add music playlist in pygame

import pygame
import time

pygame.mixer.init()
pygame.display.init()

screen = pygame.display.set_mode ( ( 420 , 240 ) )

playlist = list()
playlist.append ( "music3.mp3" )
playlist.append ( "music2.mp3" )
playlist.append ( "music1.mp3" )

pygame.mixer.music.load ( playlist.pop() )  # Get the first track from the playlist
pygame.mixer.music.queue ( playlist.pop() ) # Queue the 2nd song
pygame.mixer.music.set_endevent ( pygame.USEREVENT )    # Setup the end track event
pygame.mixer.music.play()           # Play the music

running = True
while running:
   for event in pygame.event.get():
      if event.type == pygame.USEREVENT:    # A track has ended
         if len ( playlist ) > 0:       # If there are more tracks in the queue...
            pygame.mixer.music.queue ( playlist.pop() ) # Q
