m week11

 week11

step01-1

新增GLUT專案 week11-1_keyboard

修改feeglut

找到keyboard函式

程式碼全刪

改為

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

void keyboard(unsigned char key, int x, int y)

{

    if( key == 27 ) exit(1234);

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

step01-2

新增專案 week11-2_keyboard_PlaySound

把week11-1_keyboard的程式複製到 week11-2_keyboard_PlaySound

程式碼改成

#include <windows.h>

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

void keyboard(unsigned char key, int x, int y)

{

    if( key == '1' ) PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav", NULL, SND_ASYNC);

    if( key == '2' ) PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav", NULL, SND_ASYNC);

    if( key == '3' ) PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav", NULL, SND_ASYNC);

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

按1,2,3會有do,re,mi的聲音

step02-1

開新的程式 week11-3_PlaySound

不用開GLUT專案

#include <windows.h>

#include <stdio.h>

int main()

{

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav", NULL, SND_SYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav", NULL, SND_SYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav", NULL, SND_SYNC);

    printf("Hello World\n");

}

修改

Setting

compiler

在linker settings 加入 winmm

可以修改成

#include <windows.h>

#include <stdio.h>

int main()

{

    ///絕對路徑  Absolute Path

    ///PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav", NULL, SND_SYNC);

    ///PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav", NULL, SND_SYNC);

    ///PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav", NULL, SND_SYNC);

    ///目錄的斜線可以用 兩個反斜線 \\ 或著是一個斜線 /

    PlaySound("do-re-mi/do.wav",NULL, SND_SYNC);

    ///相對路徑 Relative Path

    printf("Hello World\n");

}

step02-2

新增GLUT專案

播出mp3

week11-4_CMP3_Load_Play

把CMP3_MCI.h 丟進 week11-4_CMP3_Load_Play 專案

修改程式碼

在137行加入

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

在143行加入

char filename[] = "C:/Users/Administrator/Desktop/do-re-mi/suzume.mp3";

myMP3.Load(filename);

myMP3.Play();

step03-1

更改工作執行目錄

打開Project

選擇properties

選擇Build targets

把Execution working dir: 改成 .

把freeglut的bin裡的freeglut.dll 丟到專案裡

並寫把mp3檔丟到專案裡

修改程式碼

第141行

///char filename[] = "C:/Users/Administrator/Desktop/do-re-mi/suzume.mp3";

///myMP3.Load(filename);

myMP3.Load("suzume.mp3");

step03-2

專案裡有 mp3檔和.dll檔

但Git會忽略.dll

導致無法備份

先用git指令叫出2023graphicsb

打開2023graphicsb裡的gitignore

用Notepad++打開

在.dll前面加#把它註解掉

然後用git上傳github
