Week11 呆江的筆記

第11周重點：聲音、音效

新的外掛：#include <mmsystem.h>
新的函式：(1) PlaySound("bubbs.wav",NULL,SND_ASYNC);  ///不同步
                   (2) PlaySound("bubbs.wav",NULL,SND_SYNC);  ///同步

來試著讓Hello world!撥出音樂吧~

#include <stdio.h>
#include <windows.h>
#include <mmsystem.h>

int main()
{
    PlaySound("bubbs.wav",NULL,SND_SYNC);
    printf("Hello world!");
    return 0;
}

需增加幾個步驟：

先選取專案

對專案按右鍵選取Bulid options...

到Linker settings新增winmm

這樣Hello world!就會有聲音啦~~

§因為小的選擇同步，所以會等音樂結束才會出現Hello world (。･∀･)ﾉ

那如果想做遊戲...
範例：打茶壺(?

#include <GL/glut.h>
#include <mmsystem.h>

static void display(void) ///畫茶壺
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glutSolidTeapot(0.5);
    glutSwapBuffers();
}
void mouse(int button,int state,int x,int y) /// 點擊滑鼠後，播放打擊聲
{
    if(state == GLUT_DOWN)  PlaySound("thwap2.wav",NULL,SND_ASYNC);
}

const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };
const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };
const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };
const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat high_shininess[] = { 100.0f };

int main(int argc, char *argv[])
{
    PlaySound("bubbs.wav",NULL,SND_ASYNC); ///播放泡泡聲
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("05163021");

    glutDisplayFunc(display);
    glutMouseFunc(mouse);

    glClearColor(1,1,1,1);
    glEnable(GL_CULL_FACE);
    glCullFace(GL_BACK);

    glEnable(GL_DEPTH_TEST);

    glEnable(GL_LIGHT0);
    glEnable(GL_NORMALIZE);
    glEnable(GL_COLOR_MATERIAL);
    glEnable(GL_LIGHTING);

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);
    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);
    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);
    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);
    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);
    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);
    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();
}

執行結果：(滑鼠點擊後)
