播聲音、mp3檔
1.勇另一種的寫法再試一次，先放一個不存在的音檔，然後去Setting裡的Compiler內設定Linker setting 加入 winmmm
程式碼如下:
```c
#include <windows.h>
int main()
{
PlaySound("badbadbad.wav",NULL,SND_SYNC); ///上週教SND_ASYNC
}///Compile成功 但link失敗
```
程式碼如下:
```c
#include <windows.h>
int main()
{
///PlaySound("badbadbad.wav",NULL,SND_SYNC);
PlaySound("07042111.wav",NULL,SND_SYNC);
}
```
3.播音樂前顯示文字，結束後顯示文字，最後在輸入數字已結束
程式碼如下:
```c
#include <windows.h>
#include <stdio.h>
int main()
{
printf("現在在PlaySound()前\n");
PlaySound("07042111.wav",NULL,SND_SYNC);
printf("現在在PlaySound()後\n");
int N;
scanf("%d",&N); ///等你輸入數字
}
```
///mp3檔案小 vs. wav檔案大 PlaySound()
程式碼如下:
```c
#include "CMP3_MCI.h"///下載放到同目錄
#include <stdio.h>
CMP3_MCI mp3;
int main()
{
mp3.Load("07042111.mp3");
mp3.Play();
printf("現在正在播放羊聲音\n");
int N; ///找一個人卡住，不要結束
scanf("%d",&N);
}
```
播放動畫、內插
1.File-New-Project,Glut 專案，將上週Week14-angle_TRT_write_and_read程式碼放入
目標:每擺出一個動作就按's'存一次檔案，這樣就不會每動一次關節就存一次檔，導致黑框很亂
程式碼如下:
修改keyboard()函式內程式碼
if(key=='r')myRead();
if(key=='s')myWrite();///save
修改motion函式內程式碼
把myWrite(); 註解掉
2.
機器人擺動作、跳舞
1.開心檔案，把舊的display函式改名，寫一個新的display函式出來
2.要把模型弄出來，必須有glm.h、glm.cpp
2-1:freeglut.dll、glm.cpp、glm.h加到你程式的工作目錄裡
2-2:左邊的專案，右鍵add把glm.cpp加進去
2-3:程式碼加進去，display函式開頭也必須加入
```c
#include "glm.h"
GLMmodel*pmodel=NULL;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
if(pmodel==NULL)
{
pmodel = glmReadOBJ("data/Gundam.obj");
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel,90);
}
glmDraw(pmodel,GLM_SMOOTH);
glutSwapBuffers();
}
```
2-4:小心!working_dir " "裡要改成"."，從專案裡的cbp檔用notepad++打開
前置作業:先將gundam裡面所有的obj檔、mtl檔放到專案中，可創一個data資料夾來存放，接著再丟入glm.cpp、glm.h、freeglut.dll，然後將cbp檔用notepad++打開，更改working _dir="."，Add files glm.cpp
程式碼如下:
```c
#include <GL/glut.h>
#include <stdio.h>
#include "glm.h"
