今日主題:加入音樂檔

開啟codeblock新增一個project

到網路上下載一個wav音樂檔

將音樂檔路逕貼到PlaySound裡面

注意!反斜線加英文會有特殊用意所以要再加一條反斜線

此時執行檔案還是會有錯誤!!!

解決方法:加入連結

在專案按右鍵build option

在link加入加入winmm

執行程式碼後就能播出音檔的聲音了

程式碼:
#include <windows.h>///(0)為了mmsystem.h裡面有些宣告,需要在之前有windows.h #include<mmsystem.h>///(1)MultiMedia System可播聲音 int main() { PlaySoundA("C:\\Users\\user\\Downloads\\thunder_clap.wav",NULL,SND_SYNC); ///(2)播放聲音ascii版Wav檔thunder_clap.wav ///空 ///聲音等待同步 return 0; }

2.邊播聲音邊開下個視窗

(1)複以前的步驟:搜尋freeglut->下載->解壓縮拖移到桌面->複製、改檔名(libglut32.a)->
開啟codeblock新建一個新的GLUT project

(2)在程式碼裡加入下面幾行

#include <stdio.h> #include<mmsystem.h>///(1)MultiMedia System可播聲音 int main(int argc, char *argv[]) { PlaySoundA("C:\\Users\\user\\Downloads\\thunder_clap.wav",NULL,SND_ASYNC); ///(2)播放聲音ascii版Wav檔thunder_clap.wav ///空 ///SND_ASYNC聲音等待不同步 printf("邊播聲音繼續開下面視窗\n");

(3)做出簡單鋼琴:用鍵盤1245控制發出do re mi fa so

#include<mmsystem.h>///now2:現在要在這個keyboard函式裡做出簡單的鋼琴 static void key(unsigned char key, int x, int y) { if(key=='1')PlaySoundA("C:\\Users\\user\\Downloads\\do.wav",NULL,SND_ASYNC);
///now2:現在要在這個keyboard函式裡做出簡單的鋼琴 if(key=='2')PlaySoundA("C:\\Users\\user\\Downloads\\re.wav",NULL,SND_ASYNC);
///now2:現在要在這個keyboard函式裡做出簡單的鋼琴 if(key=='3')PlaySoundA("C:\\Users\\user\\Downloads\\mi.wav",NULL,SND_ASYNC);
///now2:現在要在這個keyboard函式裡做出簡單的鋼琴 if(key=='4')PlaySoundA("C:\\Users\\user\\Downloads\\fa.wav",NULL,SND_ASYNC);
///now2:現在要在這個keyboard函式裡做出簡單的鋼琴 if(key=='5')PlaySoundA("C:\\Users\\user\\Downloads\\so.wav",NULL,SND_ASYNC);
///now2:現在要在這個keyboard函式裡做出簡單的鋼琴

(4)要將這個檔案下載下來丟進專案檔裡面

執行後就會先播出打雷聲接著按12345就能控制do re mi fa so

(5)讀入mp3檔

#include "CMP3_MCI.h"///(1)這個外掛不是系統有的,而是放在我們程式專案目錄裡面 CMP3_MCI myMP3;///(2)宣告一個物件變數 myMP3;

myMP3.Load("C:\\Users\\user\\Downloads\\music.mp3");///now3(3)Load讀入mp3檔 myMP3.Play();///now3(4)play播放 ///PlaySoundA("C:\\Users\\user\\Downloads\\thunder_clap.wav",NULL,SND_ASYNC); ///(2)播放聲音ascii版Wav檔thunder_clap.wav ///空 ///SND_ASYNC聲音等待不同步

執行出來後可開啟視窗播放mp3檔

--------------------------------------------------------------------------------------------------------------------------
全部程式碼:

myMP3.Load("C:\\Users\\user\\Downloads\\music.mp3");///now3(3)Load讀入mp3檔 myMP3.Play();///now3(4)play播放

#include "CMP3_MCI.h"///(1)這個外掛不是系統有的,而是放在我們程式專案目錄裡面

CMP3_MCI myMP3;///(2)宣告一個物件變數 myMP3;
