使用pygame怎么制作一個音樂播放器？針對這個問題，這篇文章詳細介紹了相對應的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。
1、準備工作
ide：pycharm
python：3.7
三方包：pygame、pyinstaller、mutagen
幾首mp3格式的歌
2、開始
2.1 設計說明
1、包含 上一首、下一首、暫停/播放、快進/快退、顯示當前播放的歌曲名稱、顯示播放進度條
2、使用pygame.mixer
3、隨機播放磁盤某個目錄及其子目錄下的mp3文件
4、上一首、下一首用隨機選擇choice(list) 實現
5、進度條用按照一定速度移動進度圖片來實現，過程中處理暫停、快進
6、歌曲快進播放用pygame.mixer.music.play(0,d_song_time) 實現
7、暫停用pygame.mixer.music.pause() 實現
8、播放用pygame.mixer.music.unpause() 實現
9、用mutagen.mp3來獲取mp3信息
2.2 代碼邏輯
收集某個目錄下的所有mp3
# 收集某個目錄及子目錄下的MP3格式的文件
# 返回歌曲路徑、歌曲時長
# [['E:\\musics\\Mirror_Yohee_128K.mp3', 236], ['E:\\musics\\over here_Nobigdyl_128K.mp3', 188], ['E:\\musics\\塵_薛之謙_128K.mp3', 282], ['E:\\musics\\aaa\\塵_薛之謙_128K.mp3', 282]]
def collect_songs(fidir):
musics =[]
for root, dirs, files in os.walk(fidir):
for file in files:
tmp =[]
if file.endswith('mp3'):
file = os.path.join(root,file)
song = MP3(file)
duration = round(song.info.length)
tmp.append(file)
tmp.append(duration)
musics.append(tmp)
return musics顯示歌曲名稱
# 把歌曲名字顯示在播放器上
def draw_song_name(music):
# 取歌曲名
music_name = music[0].split("\\")[-1]
# print(music_name)
wbk_obj = font_obj.render(music_name, True, (0, 255, 255))
k_obj = wbk_obj.get_rect()
k_obj.center = (340, 200)
screen.blit(wbk_obj, k_obj)
pygame.display.update()播放歌曲
# 隨機播放一首歌
def sing_a_song(musics):
# 隨機選擇一首音樂
music = choice(musics)
print(type(musics))
pygame.mixer.music.load(music[0])
pygame.mixer.music.play()
print('開始播放：%s -- %s秒'%(music[0] , str(music[1])))
return music顯示播放進度
# 播放進度顯示 def move(current_time,start_time,pause_duration_time,c_music): if pause_end_time == 0 and pause_start_time != 0: duration_time = round(pause_start_time - start_time - pause_duration_time) else: duration_time = round(current_time - start_time - pause_duration_time) song_total_time = c_music[1] speed = (end_x-begin_x)/song_total_time current_x = begin_x + duration_time*speed try: screen.blit(dian,(current_x,148)) pygame.display.update() except: print(current_time) print(start_time) print(pause_duration_time) exit()
快進快退功能
# 快進快退功能 def kuaijin(jindu_x,c_music): # 要跳轉到的距離d_x d_x = jindu_x - begin_x song_total_time = c_music[1] # 要跳轉到的時間d_song_time d_song_time = round(song_total_time*(d_x/560),1) # 將歌曲快進到d_song_time pygame.mixer.music.play(0,d_song_time)
畫播放控件
# 畫播放控件 def draw_kongjian(is_sing,is_pause): # 畫進度條 # 畫一條寬度為2的線，y高度為149，x從40到600,顏色為(0,100,100) pygame.draw.line(screen, (0, 100, 100), (40, 149), (600, 149), 2) # 畫播放、暫停按鈕 # 先畫圓邊框，半徑20 pygame.draw.circle(screen, (0, 255, 255), (x + 80, 100), 20, 2) # 畫三角形，開始播放 pygame.draw.line(screen, (0, 255, 255), (x + 73.7, 107.5), (x + 73.7, 93), 2) # 豎線 # 如果正在播放且沒有暫停 if is_sing and not is_pause: # 隱藏三角形 pygame.draw.line(screen, (0, 89, 115), (x + 73.7, 107.5), (x + 87.3, 100), 2) pygame.draw.line(screen, (0, 89, 115), (x + 73.7, 93), (x + 87.3, 100), 2) # 顯示第二條豎線 pygame.draw.line(screen,(0,255,255),(x+83.7,107.5),(x+83.7,93),2) else: # 隱藏第二條豎線 pygame.draw.line(screen, (0, 89, 115), (x + 83.7, 107.5), (x + 83.7, 93), 2) # 顯示三角形 pygame.draw.line(screen,(0,255,255),(x+73.7,107.5),(x+87.3,100),2) pygame.draw.line(screen,(0,255,255),(x+73.7,93),(x+87.3,100),2) # 畫上一首按鈕 pygame.draw.line(screen, (0, 255, 255), (x - 10, 110), (x - 10, 90), 2) pygame.draw.line(screen, (0, 255, 255), (x - 10, 100), (x + 10, 115), 2) pygame.draw.line(screen, (0, 255, 255), (x - 10, 100), (x + 10, 85), 2) pygame.draw.line(screen, (0, 255, 255), (x + 10, 115), (x + 10, 85), 2) # 畫下一首按鈕 pygame.draw.line(screen, (0, 255, 255), (x + 170, 110), (x + 170, 90), 2) pygame.draw.line(screen, (0, 255, 255), (x + 170, 100), (x + 150, 115), 2) pygame.draw.line(screen, (0, 255, 255), (x + 170, 100), (x + 150, 85), 2) pygame.draw.line(screen, (0, 255, 255), (x + 150, 115), (x + 150, 85), 2)
主邏輯
1、畫界面
2、如果沒有在播放音樂，播放之
3、如果正在播放音樂，刷新播放進度
4、點擊了上一首的處理
5、點擊了暫停/播放的處理
6、點擊了下一首的處理
7、快進/快退的處理
