[英]How can I make music play in the background of my py game?

這是我在 mu 編輯器中制作的 pygame,有 2 名玩家試圖躲避敵人並試圖收錢。 我想在我的 pygame 的后台添加一首歌,我該怎么做? 我試圖在 mu 編輯器的音樂文件夾中放置一個 mp3 文件,但我不確定要放入什么代碼才能使其在游戲中播放。
使用 PyGame 的混音器功能添加音樂非常容易。 使用一個頻道播放音樂,使用另一個頻道播放任何音效。 這些“混合”在一起。 一個“問題”是混音器不喜歡 MP3 文件,因此您需要將聲音轉換為 .OGG 或其他支持的格式(使用Audacity之類的格式)。 這是由於 MP3 格式受專利保護(是否已過期?)。
無論如何,所以想法是制作兩個pygame.mixer.Channel
,一個用於音樂,一個用於聲音。
pygame.mixer.init()
# create separate Channel objects for simultaneous playback
channel1 = pygame.mixer.Channel(0) # argument must be int
channel2 = pygame.mixer.Channel(1)
# Load and play a continuously looping music
background_sound = pygame.mixer.Sound( 'background_music.ogg' )
channel1.play( background_sound, -1 ) # loop the music forever
所以現在背景音樂將在channel1
上永遠循環播放。
要播放單獨的基於事件的聲音,請使用channel2
:
whack_sound = pygame.mixer.Sound( 'whack.ogg' )
bloop_sound = pygame.mixer.Sound( 'bloop-bloop.ogg' )
# In main loop
[...]
channel2.play( bloop_sound )
