移動的球

void setup()
{
  size(500,500);
}
int x = 250,y=250;
void draw()
{
  ellipse(x,y,10,10);
  x = x+1;
  y = y-1;
}

會反彈的球

void setup()

{

  size(500,500);

}

float x = 250,y=250;

float vx = 1.0,vy = -0.5;

void draw()

{

  ellipse(x,y,10,10);

  x = x + vx;

  y = y + vy;

  if( x > 500) vx = -vx;

  if(y > 500) vy = -vy;

  if(x < 0) vx = -vx;

  if(y < 0) vy = -vy;

}

乒乓球

void setup()

{

  size(500,500);

}

float x = 250,y=250;

float vx = 2.0,vy = -1.5;

void draw()

{

  background(#FFFFFF);

  float boardX = mouseX;

  rect(boardX,470,100,20,20);

  ellipse(x,y,10,10);

  x = x + vx;

  y = y + vy;

  if( x > 500) vx = -vx;

  if(x < 0) vx = -vx;

  if(y < 0) vy = -vy;

  if(y>470 && x>boardX && x<boardX+100) vy = -vy;

}

乒乓球有加速度

void setup()

{

  size(500,500);

}

float x = 250,y=250;

float vx = 2.0,vy = -1.5;

float boardX,boardY = 470,boardW = 100,boardH = 20;

void draw()

{

  background(#FFFFFF);

  boardX = mouseX-boardW/2;

  rect(boardX,boardY,boardW,boardH,20);

  ellipse(x,y,10,10);

  x = x + vx;

  y = y + vy;

  if( x > 500) vx = -vx;

  if(x < 0) vx = -vx;

  if(y < 0) vy = -vy;

  if((y>boardY && y<boardY+boardH) && (x>boardX && x<boardX+boardW))

  {

    vy = -vy;

    vx += (mouseX-pmouseX)/2;

  }

}

圍棋

void setup()

{

  size(500,500);

}

void draw()

{

  for(int x=50;x<=450;x+=50)

  {

    for(int y=50;y<=450;y+=50)

    {

      ellipse(x,y,50,50);

    }

  }

}

圍棋(更新)

void setup()

{

  size(500,500);

}

};

void draw()

      else fill(255);

      ellipse(50+j*50,50+i*50,50,50);

    }

  }
