交給函式來做事
void saveAll() (自己寫的函式)全部存檔
{ 裡面宣告,不會讓外面記起來
if(fout==NULL) fout=fopen("motion.txt", "w+"); 開檔
for(int i=0; i<10; i++){ for迴圈,把陣列全用
printf( "%d ", angle[i]); 印畫面
fprintf(fout, "%d ", angle[i]); 寫檔案
}
printf( "\n"); 跳行
fprintf(fout, "\n"); 跳行
}
void motion(int x, int y)
{ 滑動,更新 angleID對應的angle[]
angle[angleID] += (x-oldX);
oldX=x;
(自己寫的函式)全部存檔
glutPostRedisplay();
}
void readAll()
{
if(fin==NULL) fin=fopen("motion.txt", "r");///TODO4 開檔
for(int i=0; i<10; i++){
///scanf( "%d", &a[i]);
fscanf(fin, "%d", &angle[i]);///TODO4 讀檔
}
}
void keyboard(unsigned char key, int x, int y)
{ 鍵盤,選angleID
if(key=='0') angleID=0;
if(key=='1') angleID=1;
if(key=='2') angleID=2;
if(key=='3') angleID=3;
if(key=='s') saveAll();
調好動作,存檔
if(key=='r'){ 撥放
readAll();
glutPostRedisplay();
}
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Week14 file");
glutDisplayFunc(display);
glutMouseFunc(mouse); 備份(old)mouse位置
glutMotionFunc(motion); 滑動,更新 angleID對應的angle[]
glutKeyboardFunc(keyboard); 鍵盤,選angleID
glutMainLoop();
}
