程序名：PyMusic
解释：pygame+music
之前发布了自己写的小程序：百度随心听音乐播放器的一些效果图
你可以去到这里再次看看效果：
这个程序的灵感来自于百度随心听
说明：
动作按钮全部是画出来的，没有用到任何图片
用到图片的只有：背景，歌手图片，作者图片
经过一个阶段的调试，现在算是可以拿上台面和大家交流
功能介绍：
A.四个按钮介绍
1.完成停止，播放音乐功能
2.喜欢/不喜欢当前所播放的音乐
3.删除当前所播放的音乐(物理环境下不会删除，删除的是内存中的)
4.下一曲
5.当鼠标经过按钮的时候，按钮颜色会变化
B.状态栏(最下面)
1.显示所有歌曲数(AllSongs)
2.当前播放的歌曲是第只歌曲
3.当前音量(范围：0 - 10)
4.音量的图形显示(这里没有用到图片，而是系统画出来的:-))
5.我的邮箱信息：hongtenzone@foxmail.com
C.右下角
1.当鼠标移动到黄色圆区域，会展示出我的相片和'Yes,You are Luck:)'字样
鼠标一开的时候会自动隐藏（我想接触过android系统手机的的朋友，可能有这样的经历，在工具里面有一个地方
当点击三下的时候，会出现android里面的一副图片....对我这里的灵感来自于这里ll）
=======================================
下面我说说我做的思路吧
我想有一部分朋友会喜欢的...:)
首先，主题功能是音乐播放，那么我们就应该实现这个音乐播放的功能
哈哈，这个灵感来自于我之前写的小游戏：
在这个游戏中，我实现了音乐的播放，于是乎我就想在音乐播放上面做一些文章...
接下来是程序PyMusic的主题界面需要考虑，我个人喜欢听歌...百度音乐，百度随心听都是常去的地方..
百度随心听的界面设计简洁，很适合我的风格...所以我选择了百度随心听..
于是乎我看是看百度随心听的代码...一不小心被我大概看明白了按钮之间的逻辑....
一时间，头脑中出现了PyMusic的原型....
为什么不做一个呢？我就这样问着我自己，慢慢在脑海中呈现PyMusic的原型...
然后开始动笔，把pyMusic的原型在纸上画了出来....
画好了，就开始分析...(这个过程有一点长..)
然后把原型中的物体（按钮，图片加载..）一个一个的实现..
最后加上我的小自信..呵呵，成啦..
=======================================
一些细节
在做PyMusic的过程中，需要注意一些细节的地方
我下面把这些地方罗列出来
1.音量图形的初始化
1 VOLUME_POINTS = [] 2 VOLUME_POINTS_START = [] 3 VOLUME_RECT_COLORS = [] 4 for p in range(170, 250, 7): 5 VOLUME_POINTS.append([SCREEN_W - p,SCREEN_H + 20]) 6 for ps in range(175, 250, 7): 7 VOLUME_POINTS_START.append([SCREEN_W - ps, SCREEN_H]) 8 VOLUME_RECT_COLORS.append((randint(0, 255), randint(0, 255), randint(0, 255)))
2.加载歌曲和图片
1 SONG_ARRAY = [] 2 SONG_IMAGE = [] 3 for song in range(len(SONGS)): 4 SONG_ARRAY.append(pygame.mixer.Sound(os.path.join(DATA_DIR, SOUND_DIR, SONGS[song][0]))) 5 SONG_IMAGE.append(pygame.image.load(os.path.join(DATA_DIR, IMAGE_DIR, SONGS[song][3])).convert())
3.字体加载
1 font = pygame.font.Font(os.path.join(DATA_DIR, FONT_DIR, 'TORK____.ttf'), 14) 2 font_song_title = pygame.font.Font(os.path.join(DATA_DIR, FONT_DIR, 'msyhbd.ttf'), 24) 3 font_song = pygame.font.Font(os.path.join(DATA_DIR, FONT_DIR, 'msyh.ttf'), 16)
4.停止/播放按钮
1 def button_play(screen, color): 2 pygame.draw.circle(screen, color, CIRCLES_POS[0], CIRCLR_R, CIRCLR_W) 3 points=[(77,340),(77,360),(95,350)] 4 pygame.draw.polygon(screen,color,points) 5 6 def button_stop(screen, color): 7 pygame.draw.circle(screen, color, CIRCLES_POS[0], CIRCLR_R, CIRCLR_W) 8 pygame.draw.rect(screen, 9 color, 10 Rect(77, 340, 5, 23 )) 11 pygame.draw.rect(screen, 12 color, 13 Rect(88, 340, 5, 23 ))
5.删除歌曲按钮
1 def button_del(screen, color): 2 pygame.draw.circle(screen, color, CIRCLES_POS[2], CIRCLR_R, CIRCLR_W) 3 pygame.draw.circle(screen, color, (215, 340), 6, 3) 4 pygame.draw.rect(screen, 5 color, 6 Rect(200, 340, 30, 6 )) 7 pygame.draw.rect(screen, 8 color, 9 Rect(204, 340, 3, 20 )) 10 pygame.draw.rect(screen, 11 color, 12 Rect(210, 340, 3, 20 )) 13 pygame.draw.rect(screen, 14 color, 15 Rect(217, 340, 3, 20 )) 16 pygame.draw.rect(screen, 17 color, 18 Rect(223, 340, 3, 20 )) 19 pygame.draw.rect(screen, 20 color, 21 Rect(204, 360, 22, 5 ))
6.作者信息展示
1 def button_authon_image(screen, color):
2 pygame.draw.circle(screen, color, CIRCLES_POS[4], CIRCLR_R, CIRCLR_W)
3 pygame.draw.rect(screen,
4 (255, 255, 255),
5 Rect(418, 248, 144, 154 ))
6 screen.blit(author_image, (420, 250))
7 luck = font_song_title.render('Yes, You are Luck :-)', True, (255,165,10))
8 screen.blit(luck, (280, 416))
7.第一个监听器
1 def listener(): 2 global PLAY_FLAG 3 global PREFER_FLAG 4 x, y = pygame.mouse.get_pos() 5 color = (255,255,25) 6 color_red = (230, 0, 0) 7 for index in range(len(CIRCLES_POS)): 8 p_x = (CIRCLES_POS[index][0] - x)**2 9 p_y = (CIRCLES_POS[index][1] - y)**2 10 p_r = (CIRCLR_R)**2 11 if (p_x + p_y <= p_r): 12 if index == 0 and PLAY_FLAG: 13 button_stop(screen, color) 14 elif index == 0 and not PLAY_FLAG: 15 button_play(screen, color) 16 elif index == 1 and PREFER_FLAG: 17 button_perfer(screen, color) 18 elif index == 1 and not PREFER_FLAG: 19 button_perfer(screen, color_red) 20 elif index == 2: 21 button_del(screen, color) 22 elif index == 3: 23 button_next_song(screen, color) 24 elif index == 4: 25 button_authon_image(screen, color)
8.第二个监听器
1 def mouse_down_listener(sound):
2 global PLAY_FLAG
3 global PREFER_FLAG
4 global SONG_FLAG
5 x, y = pygame.mouse.get_pos()
6 for index in range(len(CIRCLES_POS)):
7 p_x = (CIRCLES_POS[index][0] - x)**2
8 p_y = (CIRCLES_POS[index][1] - y)**2
9 p_r = (CIRCLR_R)**2
10 if (p_x + p_y <= p_r):
11 if index == 0 and PLAY_FLAG:
12 #print('stop now......')
13 sound.stop()
14 PLAY_FLAG = False
15 elif index == 0 and not PLAY_FLAG:
16 #print('play now ... ... ... ...')
17 sound.play(0)
18 PLAY_FLAG = True
19 elif index == 1 and PREFER_FLAG:
20 print('perfer song....<<', SONGS[SONG_FLAG][1], '>>')
21 PREFER_FLAG = False
22 elif index == 1 and not PREFER_FLAG:
23 print('not perfer song... <<', SONGS[SONG_FLAG][1], '>>')
24 PREFER_FLAG = True
25 elif index == 2:
26 sound.stop()
27 print('delete song....<<', SONGS[SONG_FLAG][1], '>>')
28 if SONG_FLAG > 0:
29 SONGS.pop(SONG_FLAG)
30 SONG_IMAGE.pop(SONG_FLAG)
31 SONG_ARRAY.pop(SONG_FLAG)
32 if SONG_FLAG >= len(SONGS) - 1:
33 SONG_FLAG -= 1
34 else:
35 print('This is the last song.')
36 elif index == 3:
37 sound.stop()
38 if SONG_FLAG < len(SONGS) - 1:
39 SONG_FLAG += 1
40 else:
41 SONG_FLAG = 0
42 #print('next song....')
43
9.鼠标按下事件
1 elif event.type == MOUSEBUTTONDOWN: 2 pressed_array = pygame.mouse.get_pressed() 3 for index in range(len(pressed_array)): 4 if pressed_array[index]: 5 if index == 0: #When the LEFT button down 6 mouse_down_listener(bg_sound)
上面的都是一些细节的地方...

你在运行的时候，肯恩会遇到一些问题，系统找不到音乐和图片....
这个由于文件中的音乐，字体和图片有一点大，所以我把图片和音乐删掉..你可以进行添加即可
还请大家给我想想办法，我好上传源文件给大家伙下载...
