P.S.      GLUT有幾個重要的函式

今天是要模仿網路上的射擊遊戲

設計出一個更簡單的程式

首先先去試試看打光跟貼圖的範例

之後就進入主題

開始寫一個程式

些出了成果是一個全螢幕的畫面

然後滑鼠點擊的時候會出現槍聲

P.S.   環境都要設置好

音檔的部分也要放對地方

(將要使用到的音檔放入freeglut\bin裡)

#include <GL/glut.h>

#include <mmsystem.h>

#include <stdio.h>

void mouse (int button, int state, int x, int y)

{

    if (state==GLUT_DOWN)

    {

        PlaySound("Shot.wav", NULL, SND_ASYNC);

        printf("Shot!\n");

    }

}

void keyboard(unsigned char key, int x, int y)

{

    exit(0);

}

void display()

{

    glClearColor(0.5,0.5,1,0);

    glClear(GL_COLOR_BUFFER_BIT);

    glFlush();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("02161034");

    glutFullScreen();

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

接下來加入一個會動的茶壺

滑鼠依舊按下去有槍聲

#include <GL/glut.h>

#include <mmsystem.h>

#include <stdio.h>

void mouse (int button, int state, int x, int y)

{

    if (state==GLUT_DOWN)

    {

        PlaySound("Shot.wav", NULL, SND_ASYNC);

        printf("Shot!\n");

    }

}

void keyboard(unsigned char key, int x, int y)

{

    exit(0);

}

float potX=-1, potY=0;

void display()

{

    potX+=0.01;

    if(potX>1.1) potX=-1.1;

    glClearColor(0.5,0.5,1,0);

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

    glTranslatef(potX,potY,0);

    glutSolidTeapot(0.05);

    glPopMatrix();

    glFlush();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("02161034");

    glutFullScreen();

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

接下來加上判別是否射中目標的程式

射中了就播放青蛙聲

#include <GL/glut.h>

#include <mmsystem.h>

#include <stdio.h>

#include <math.h>

float potX=-1, potY=0;

void mouse (int button, int state, int x, int y)

{

    if (state==GLUT_DOWN)

    {

        PlaySound("Shot.wav", NULL, SND_ASYNC);

        printf("Shot!\n");

        float mouseX=2*x/1280.0 -1, mouseY=2*y/1024.0 -1;

        if(fabs(mouseX-potX) <0.1 && fabs(mouseY -potY)<0.1)

        {

            PlaySound("ahh.wav",NULL, SND_ASYNC);

            printf("You Got It!\n");

        }

    }

}

void keyboard(unsigned char key, int x, int y)

{

    exit(0);

}

void display()

{

    potX+=0.01;

    if(potX>1.1) potX=-1.1;

    glClearColor(0.5,0.5,1,0);

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

    glTranslatef(potX,potY,0);

    glutSolidTeapot(0.05);

    glPopMatrix();

    glFlush();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("02161034");

    glutFullScreen();

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

貼圖的部分今天來不及學到

下下禮拜繼續~~~
