pygame系列_原創百度隨心聽音樂播放器_完整版

本文轉載自查看原文 2013-10-23 23:41 7124 python/ pygame/ pygame系列/ pymusic/ Python

程序名：PyMusic

解釋：pygame+music

之前發布了自己寫的小程序：百度隨心聽音樂播放器的一些效果圖

你可以去到這里再次看看效果：

pygame系列_百度隨心聽_完美的UI設計

這個程序的靈感來自於百度隨心聽

說明：

動作按鈕全部是畫出來的，沒有用到任何圖片

用到圖片的只有：背景，歌手圖片，作者圖片

經過一個階段的調試，現在算是可以拿上台面和大家交流

hongten_pymusic

功能介紹：

A.四個按鈕介紹

1.完成停止，播放音樂功能

2.喜歡/不喜歡當前所播放的音樂

3.刪除當前所播放的音樂(物理環境下不會刪除，刪除的是內存中的)

4.下一曲

5.當鼠標經過按鈕的時候，按鈕顏色會變化

B.狀態欄(最下面)

1.顯示所有歌曲數(AllSongs)

2.當前播放的歌曲是第只歌曲

3.當前音量(范圍：0 - 10)

4.音量的圖形顯示(這里沒有用到圖片，而是系統畫出來的:-))

5.我的郵箱信息：hongtenzone@foxmail.com

C.右下角

1.當鼠標移動到黃色圓區域，會展示出我的相片和'Yes,You are Luck:)'字樣

鼠標一開的時候會自動隱藏（我想接觸過android系統手機的的朋友，可能有這樣的經歷，在工具里面有一個地方

當點擊三下的時候，會出現android里面的一副圖片....對我這里的靈感來自於這里ll）

=======================================

下面我說說我做的思路吧

我想有一部分朋友會喜歡的...:)

首先，主題功能是音樂播放，那么我們就應該實現這個音樂播放的功能

哈哈，這個靈感來自於我之前寫的小游戲：

pygame系列_小球完全彈性碰撞游戲_源碼下載

在這個游戲中，我實現了音樂的播放，於是乎我就想在音樂播放上面做一些文章...

接下來是程序PyMusic的主題界面需要考慮，我個人喜歡聽歌...百度音樂，百度隨心聽都是常去的地方..

百度隨心聽的界面設計簡潔，很適合我的風格...所以我選擇了百度隨心聽..

於是乎我看是看百度隨心聽的代碼...一不小心被我大概看明白了按鈕之間的邏輯....

一時間，頭腦中出現了PyMusic的原型....

為什么不做一個呢？我就這樣問着我自己，慢慢在腦海中呈現PyMusic的原型...

然后開始動筆，把pyMusic的原型在紙上畫了出來....

畫好了，就開始分析...(這個過程有一點長..)

然后把原型中的物體（按鈕，圖片加載..）一個一個的實現..

最后加上我的小自信..呵呵，成啦..

=======================================

一些細節

在做PyMusic的過程中，需要注意一些細節的地方

我下面把這些地方羅列出來

1.音量圖形的初始化

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.加載歌曲和圖片

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.字體加載

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/播放按鈕

 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.刪除歌曲按鈕

 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.第一個監聽器

 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.第二個監聽器

 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.鼠標按下事件

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)

上面的都是一些細節的地方...

你在運行的時候，肯恩會遇到一些問題，系統找不到音樂和圖片....

這個由於文件中的音樂，字體和圖片有一點大，所以我把圖片和音樂刪掉..你可以進行添加即可

還請大家給我想想辦法，我好上傳源文件給大家伙下載...
