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
FILE * fout = NULL, * fin = NULL;
void myWrite(){
if(fout==NULL) fout= fopen("file.txt", "w+");
for(int i=0; i<20; i++){
printf("%.2f ", angle[i]);
fprintf(fout, "%.2f ", angle[i]);
}
printf("\n");
fprintf(fout, "\n");
///少了fclose，因為不想印一行就結束，要多行一點
}
void myRead()
{
if(fout!=NULL){ /// 還在讀的檔案關掉
fclose(fout);
fout=NULL;
}
if(fin==NULL) fin= fopen("file.txt", "r");
for(int i=0; i<20; i++){
fscanf(fin, "%f", &angle[i]);
}
glutPostRedisplay(); ///重畫畫面
}
void keyboard(unsigned char key, int x, int y)
{
if(key == '0') angleID=0; ///預設
if(key == '1') angleID=1;

}
void mouse(int button, int state, int x, int y)
{
oldX= x;
}
void motion(int x, int y)
{
angle[angleID] += (x-oldX);
///myWrite(); 沒必要一直寫檔
oldX= x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1, 1, 1); ///白色的

把glm.h、glm.cpp、gundam的data放到程式目錄
專案右鍵把glm.cpp加進來
用Notepad++把.cbp檔案中的 working_dir 改為 working_dir="."並存檔

6.分割顯示的機器人
把設定好的模型檔拉到data
設 myReadOne函式讀取模型檔
再設定一個新的display()來畫出分割過的部位
