1. 主題: 聲音、音效、音樂
2. 實作: 播放 WAV檔
3. 實作: 播放 MP3檔
4. 實作: GLUT .cbp 專案檔 的設定 (執行目錄、include/lib目錄、link lib檔)
5. 確認作業4(多個3D模型+GLUT)繳交狀況
架設好freeglut的環境>開啟專案>刪除起始內容程式>打上下方程式
#include<windows.h>
#include<mmsystem.h>
int main()
{
PlaySoundA("檔名.wav",NULL , SND_SYNC);
}
因為沒檔案會報錯，位址顯示要把檔案放在freeglut/bin中...
網路隨便下載WAV檔>放到資料夾中>添加檔名
創一個完整的檔案
下載do,re,mi檔案>寫上下方程式
#include<windows.h>#include<mmsystem.h>
#include <GL/glut.h>
void display(void)
{
}
void keyboard(unsigned char key,int x, int y)
{
if(key=='1')
PlaySoundA("do.wav",NULL , SND_ASYNC);
if(key=='2')
PlaySoundA("re.wav",NULL , SND_ASYNC);
if(key=='3')
PlaySoundA("mi.wav",NULL , SND_ASYNC);
if(key=='4')
PlaySoundA("fa.wav",NULL , SND_ASYNC);
if(key=='5')
PlaySoundA("so.wav",NULL , SND_ASYNC);
}
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("12");
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);
glutMainLoop();
}
SND_ASYNC 為即時同步, SND_SYNC 先完整撥放
讀入做出MP3檔
下載需要檔案(mp3檔,mp3引入程式)>
mp3檔放至(Freeglut/bin資料夾),mp3引入程式語言放至(專案目錄資料夾)>
寫入下方程式並填上檔名
#include<windows.h>
#include<mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h"///這樣就可以直接讀入目錄中程式語言
CMP3_MCI mp3;///宣告一個宣告物件變數
void display(void)
{
}
void keyboard(unsigned char key,int x, int y)
{
if(key=='1')
PlaySoundA("do.wav",NULL , SND_ASYNC);
if(key=='2')
PlaySoundA("re.wav",NULL , SND_ASYNC);
if(key=='3')
PlaySoundA("mi.wav",NULL , SND_ASYNC);
if(key=='4')
PlaySoundA("fa.wav",NULL , SND_ASYNC);
if(key=='5')
PlaySoundA("so.wav",NULL , SND_ASYNC);
}
int main(int argc, char *argv[])
{
mp3.Load("檔名.mp3");
mp3.Play();
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("12");
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);
glutMainLoop();
}
上面DOREMI無法同時撥放做出和弦,我們要利用使用mp3的方法解決
如下:
#include<windows.h>
#include<mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;///宣告一個宣告物件變數
CMP3_MCI Do ,Re ,Mi ,Fa ,So;
void display(void)
{
}
void keyboard(unsigned char key,int x, int y)
{
if(key=='1') Do.Play();///PlaySoundA("do.wav",NULL , SND_ASYNC);
if(key=='2') Re.Play();///PlaySoundA("re.wav",NULL , SND_ASYNC);
if(key=='3') Mi.Play();///PlaySoundA("mi.wav",NULL , SND_ASYNC);
if(key=='4') Fa.Play();///PlaySoundA("fa.wav",NULL , SND_ASYNC);
if(key=='5') So.Play();///PlaySoundA("so.wav",NULL , SND_ASYNC);
}
int main(int argc, char *argv[])
{
Do.Load("do.wav"); Re.Load("re.wav"); Mi.Load("mi.wav");
Fa.Load("fa.wav");So.Load("so.wav");
mp3.Load("Dreams.mp3");
///mp3.Play();
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("12");
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);
glutMainLoop();
}
如何把檔案放在目錄資料夾
把目錄 .cbp檔 working.dir改成"."> bin中的音樂檔 注意還有freeglut.dll 就可以放到目錄之中
最終版乒乓球小遊戲
#include <windows.h>#include <mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h" /// TODO3: 雙引號,在專案同一個目錄裡

Fa.Load("fa.wav"); So.Load("so.wav");///TODO4: 5個物件變數 設好檔案
