先複習實習課的題目

----------------------------------------------------------------------------------------------

用Processing來了解泡泡排序法

--------------------------------------------------------------------------------------------

做出Pacman

void setup(){

  size(400,400);

}

int X=100,Y=100,angle=45,diff=1;

void draw(){

  background(0);

  arc(X,Y,80,80,radians(angle),radians(360-angle),PIE);

  angle+=diff;

  if(angle>60) diff=-1;

  if(angle<0) diff=1;

} 

------------------------------------------------------------------------

讓Pacman可以移動

void setup(){

  size(400,400);

}

int X=100,Y=100,angle=45,diff=1,dx=1,dy=0;

void draw(){

  background(0);

  arc(X,Y,80,80,radians(angle),radians(360-angle),PIE);

  angle+=diff;

  if(angle>60) diff=-1;

  if(angle<0) diff=1;

  X+=dx; Y+=dy;

} 

void keyPressed(){

  if(keyCode==RIGHT){dx=1;dy=0;}

  if(keyCode==LEFT){dx=-1;dy=0;}

  if(keyCode==UP){dx=0;dy=-1;}

  if(keyCode==DOWN){dx=0;dy=1;}

}

讓Pacman的嘴巴方向可以朝著前進的方向

void setup(){

  size(400,400);

}

int X=100,Y=100,angle=45,diff=2,dx=1,dy=0,dir=0;

void draw(){

  background(0);

  arc(X,Y,80,80,radians(dir+angle),radians(dir+360-angle),PIE);

  angle+=diff;

  if(angle>60) diff=-2;

  if(angle<0) diff=2;

  X+=dx; Y+=dy;

} 

void keyPressed(){

  if(keyCode==RIGHT){dx=1;dy=0;dir=0;}

  if(keyCode==LEFT){dx=-1;dy=0;dir=180;}

  if(keyCode==UP){dx=0;dy=-1;dir=270;}

  if(keyCode==DOWN){dx=0;dy=1;dir=90;}

}

讓Pacman可以吃掉豆子

///eat bean, draw first

int [][]bean={

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

{1,1,1,1,1,1,1,1,1,1},

};

void setup(){

  size(400,400);

}

int X=100,Y=100,angle=45,diff=2,dx=1,dy=0,dir=0;

void draw(){

  background(0);

  fill(255);

  for(int y=0;y<10;y++){//小寫的y

    for(int x=0;x<10;x++){//小寫的x

      if(bean[y][x]==0) continue;

      ellipse(20+x*40,20+y*40,10,10);

      if(dist(X,Y,20+x*40,20+y*40)<20) bean[y][x]=0;

    }

  }

  fill(#FFCF0D);

  arc(X,Y,40,40,radians(dir+angle),radians(dir+360-angle),PIE);

  angle+=diff;

  if(angle>60) diff=-2;

  if(angle<0) diff=2;

  X+=dx; Y+=dy;

} 

void keyPressed(){

  if(keyCode==RIGHT){dx=1;dy=0;dir=0;}

  if(keyCode==LEFT){dx=-1;dy=0;dir=180;}

  if(keyCode==UP){dx=0;dy=-1;dir=270;}

  if(keyCode==DOWN){dx=0;dy=1;dir=90;}

 }
