Amber's note

主題:聲音

延續上週，繼續教聲音

<step1>設定settings/Linker settings/新增winmm(咒語)

<測試>寫出下面程式碼，測試系統可以正常執行

             上週教#include <mmsystem.h>

               這週教另一種用法#include <windows.h>

<step2>下載其他音檔測試，07042111.wav為音檔名

<注意>1.一定要是.wav檔，不可以是mp3檔

            2.音檔必須放在跟專案工作目錄一樣的地方

<比較ASYNC與SYNC>ASYNC會讓程式同時執行，SYNC會一行一行執行

<使用mp3檔播放>因為mp3(壓縮)的檔案比wav(沒壓縮)小所以我們試著讀mp3檔 ,

                                要include "CMP3_MCI.h"檔案、檔案可以在teams下載，放到同個專案目錄下

<TRT again>繼續教上週的動畫，修改上週 week14_TRT_angle_write_and_read程式碼，將myWrite();註解掉，將keyboard函式裡的

week15

 1.讀入聲音

#include <windows.h>

int main()

{

    PlaySound("bad.wav", NULL, SND_SYNC);///先讀入一個空檔案

}

settings->compiler->Linker settings->add"winmm"

執行出錯誤的音效後，電腦就能讀聲音了

下載聲音，將音檔放入資料夾

#include <windows.h>

int main()

{

    PlaySound("07042111.wav", NULL, SND_SYNC);

}

2.輸入數字後聲音停止

#include <windows.h>

int main()

{

    printf("現在在PlaySound前\n");

    PlaySound("07042111.wav", NULL, SND_ASYNC);///SND_SYNC要等待同步

    printf("現在在PlaySound後\n");            ///SND_ASYNC不用等待、不同步

    int N;

    scanf("%d", &N);///等你輸入數字，輸入後聲音停止

}

3.

將CMP3_MCI.h、mp3拉進資料夾

#include "CMP3_MCI.h"

#include <stdio.h>

CMP3_MCI mp3;

int main()

{

    mp3.Load("07042111.mp3");

    mp3.Play();

    printf("現在正在播放聲音\n");

    int N;

    scanf("%d", &N);///等你輸入數字，輸入後聲音停止

}

4.讀入上禮拜程式week14_TRT_angle_write_and_read，並修改

   要能擺好動作再進行存檔

   將原本motion()中的myWrite()註解掉 (使其可以不會一直寫檔)

   在keyboard()中增加一個鍵存檔->按 s ，啟動 myWrite函式，擺好動作後存檔

   存取後，按 r 讀取並回復原之前儲存的動作，關掉後重開再按 r 也可以做出動作

#include <GL/glut.h>

#include <stdio.h> ///為了 printf , fprintf, fopen, fclose

float angle[20], oldX=0; ///角度歸零

int angleID=0; ///0為第0個關節...以此類推

    }

    printf("\n");

    fprintf(fout, "\n");

    ///少了fclose，因為不想印一行就結束，要多行一點

}

{

    if(fout!=NULL){ /// 還在讀的檔案關掉

        fclose(fout);

        fout=NULL;

    }

{

week15👻

  一.開啟openGL專案

1.程式碼:

#include<stdio.h>

int main(int argc,char**argv)

{

    FILE*fout=NULL;

    fout=fopen("file.txt","w+");///檔案的指標 fout output用

    printf("Hello World\n");///開檔,使用w+模式

    fprintf(fout,"Hello World\n");

}

2.修改執行目錄位置(修改week15_file裡的Option working_dir位置改成".")

2.老師給的程式碼

程式碼:

#include <stdio.h>

#include <GL/glut.h>

float angle=0,diff=2;

void timer(int t){

    glutTimerFunc(30,timer,t+1);

    angle+=diff;

    if(angle>90)diff=-2;

    if(angle<0)diff=+2;

    glutPostRedisplay();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        ///glutSolidTeapot( 0.3 );

        glPushMatrix();

            glTranslatef(-0.3,0,0);///掛在正確的地方

            glRotatef(angle,0,0,1);///(2)旋轉

            glTranslatef(-0.3,0,0);///(1)把關節放到畫面中心

            glutSolidTeapot( 0.3 );///左手臂

            glPushMatrix();

                ///glutSolidTeapot( 0.3 );

            glPopMatrix();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main( int argc, char ** argv )

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week15 file");

    glutTimerFunc(0,timer,0);

    glutDisplayFunc(display);

    glutMainLoop();

}

程式碼:

#include <stdio.h>///可割可棄

#include <GL/glut.h>

float angle=0,diff=2;

void timer(int t){

    glutTimerFunc(30,timer,t+1);

    angle+=diff;

    if(angle>90)diff=-2;

    if(angle<0)diff=+2;

    glutPostRedisplay();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glutSolidTeapot( 0.3 );///身體

        glPushMatrix();

            glTranslatef(-0.3,0,0);

            glRotatef(angle,0,0,1);

            glTranslatef(-0.3,0,0);

    glutCreateWindow("week15 file");

    glutTimerFunc(0,timer,0);

    glutDisplayFunc(display);

    glutMainLoop();

}

3.整合多個關節

程式碼:

#include <stdio.h>///可割可棄

#include <GL/glut.h>

superidol week15

 1.新增一個空白檔案，去setting裡compiler找到linker setting 並新增winmm

2.下載老師給的wav，把聲音加進去

3.開新專案，帶入上週程式碼並新增，能讓物體看起來像動畫，每當擺好一個姿勢後按s(儲存)，然後按r，物體就會回復之前的動作。

4.做出一個全白鋼彈的程式碼

Week15

 1.新程式碼

2.Setting>compiler>linker seeting>add>輸入winmm>OK

3.如果有叮表示開啟失敗,把藥的音樂wav放到同一個資料夾

4練習SND_ASYNC

5.mp3播放

6.街上周程式碼,註解調Myrite()

7.在keyboard改美按一次s就存檔一次

8.開一個新檔,把glm.cpp.m加入資料夾,在檔案內加入glm.cpp更改目錄,改work dir="."

改display()

week15 跳舞

 1-1教新的程式碼

要變譯成功但沒有link成功

案Setting ->compiler->linker seeting->add->輸入winmm->OK

按下編譯

會有一聲"叮"(檔案開啟失敗的聲音)

將你要的音樂.wav檔名稱放到同資料夾，記得改程式裡的檔名

2-1

SND_ASYNC練習

3-1

mp3撥放

下載"CMP3_MCI.h"'裝到相同資料夾

4-1

接續上禮拜程式

目標，擺好動作再存一行

先改一行程式碼

註解掉Mywrite()

在keyboard裡

改成每案一下"S"存檔一次

5-1

開新檔案把剛寫的複製一次貼上

將glm.cpp、glm.m加進資料夾

更改工作檔案目錄

改成work dir="."

成功將檔案工作目錄改到自己的資料夾內

創建模型

GLMmodel *pmodel=NULL;

改掉display()
