15-1:
播放音效
程式碼:
#include <windows.h>
int main()
{
PlaySound("0530.wav",NULL,SND_SYNC);
}
15-2
ASYNC(不同步)(不能播MP3)
程式碼如下:
#include <windows.h>
#include <stdio.h>
int main()
{
printf("現在在playsound()前\n");
PlaySound("0530.wav",NULL,SND_ASYNC);
printf("現在在playsound()後\n");
int N;
scanf("%d",&N);程式碼運行後,輸入數字就會停下
}
15-3
能播放mp3!
程式碼:
#include "CMP3_MCI.h"
#include <stdio.h>
CMP3_MCI mp3;
int main()
{
mp3.Load("0530.mp3");
mp3.Play();
printf("現在正在播放罐頭笑聲\n");
int N;
scanf("%d",&N);
}
15-4讓圖片儲存並且動起來
程式碼如下:
#include <GL/glut.h>
#include <stdio.h>
float angle[20], oldX=0;
int angleID=0;
FILE*fout=NULL, *fin=NULL;
void myWrite()
{
if(fout==NULL) fout=fopen("file.txt", "w+");
for(int i=0; i<20; i++){
fprintf(fout, "%.2f ", angle[i]);
}
}
void myRead()
{
if(fout!=NULL){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();
}
void keyboard(unsigned char key, int x, int y)
{
if(key=='r') myRead(); 讀取儲存
if(key=='s') myWrite(); 儲存
if(key == '0') angleID=0;
if(key == '1') angleID=1;
if(key == '2') angleID=2;
if(key == '3') angleID=3;
}
void mouse(int button, int state, int x, int y)
{
oldX= x;
}
void motion(int x, int y)
{
angle[angleID] += (x-oldX);
///myWrite(); 註解掉不全部儲存
oldX= x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1, 1, 1);
glRectf(0.3, 0.5, -0.3, -0.2);
glPushMatrix();
glTranslatef(0.3, 0.4, 0);
glRotatef(angle[0], 0, 0, 1);

glTranslatef(-0.8, -0.4, 0);
glColor3f(0, 1, 0);
glRectf(0.8, 0.5, 1.1, 0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();

glColor3f(0, 1, 0);
glRectf(-0.8, 0.5, -1.1, 0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Week15 TRT again");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
