探索比奇堡的十大奧秘 13

 week13-1_glm_gundam_keyboard_angleID_mouse_motion_angle

先安裝openCV，CodeBlocks要重開

要改環境Search directories->Compiler 增加 C:\OpenCV2.1\include

Search directories->Linker 增加 C:\OpenCV2.1\lib

Linker settings-> 增加 cv210、cxcore210、highgui210

載git hub把第12周的12-3 抓下來就可以了

float angle[20] = {};///20個角度,都設成0

int angleID = 0; ///可以是角度0,角度1,角度2

void motion(int x,int y){ ///加入 mouse motion 對應的

    angle[angleID] = y;///當我們的 mouse motion 時

    glutPostRedisplay();///要重畫畫面

}

void motion(int x,int y){ ///加入 mouse motion 對應的函式

    angle[angleID] += y-oldy;///當我們的 mouse motion 時,y座標

    oldx=x;///y-oldy;加上移動多少

    oldy=y;

    glutPostRedisplay();///要重畫畫面

}

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

    oldx=x;

    oldy=y;

}

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

    if(key == '0') angleID = 0;

    if(key == '1') angleID = 1;

    if(key == '2') angleID = 2;

    if(key == '3') angleID = 3;
