 1.做一條無限延長的線

void setup()

{

  size(500,500);

}

int x=250, y=250;

void draw()

{

  ellipse(x, y, 10, 10);

  x = x + 1;

  y = y - 1;

}

線碰到牆壁會反彈

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 < 0 ) vy = -vy;

}

要接住喔!!!

void setup()

{

  size(500,500);

}

float x=250, y=250;

float vx=1.0, vy = -0.5;

void draw()

{

  background(#FFFFF2);

  int boardX = mouseX;

  rect(boardX, 470, 100, 20);

  ellipse(x ,y, 10, 10);

  x = x+vx;

  y = y+vy;

  if( x > 500 ) vx = -vx;

  if( y < 0 ) vy = -vy;

  if( x < 0 ) vx = -vx;

  if( y>470 && x>boardX && x<boardX+200 ) vy = -vy;

}

修改一下!

void setup()

{

  size(500,500);

}

float x=250, y=250; 

float vx=2.0, vy = -2.5;

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

void draw()

{

  boardX = mouseX-boardW/2;

  background(#FFFFF2);

  rect(boardX, boardY, boardW, boardH); 

  ellipse(x ,y, 10, 10); 

  x = x + vx;

  y = y + vy;

  if( x > 500 ) vx = -vx;

  if( y < 0 ) vy = -vy;

  if( x < 0 ) vx = -vx;

  if( (y>boardY && y<boardY + boardH ) &&

      (x>boardX && x<boardX + boardW ) ){

    vy = -vy;  

    vx += (mouseX-pmouseX)/2; 

  }

  if(mousePressed && mouseButton==LEFT) boardW *=1.01; 

  if(mousePressed && mouseButton==RIGHT) boardW *=0.99; 

}

來下棋

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);

    }

  }

}

怎麼可以只有白棋呢

void setup(){

  size(500,500);

}

int [][] go={

  {0,0,0,0,0,0,0,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,0,1,0,1,0,0,0},

  {0,0,0,0,1,0,0,0,0},

  {0,0,0,0,0,0,0,0,0}

};

void draw(){

  for(int i=0; i<9; i++){

    for(int j=0; j<9; j++){

      if( go[i][j]==1) fill(0);

      else fill(255);

      ellipse(50+j*50, 50+i*50, 50, 50);

    }

  }

}

加上棋盤格

void setup(){

  size(500,500);

}

int [][] go={

  {0,0,0,0,0,0,0,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,0,1,0,1,0,0,0},

  {0,0,0,0,1,0,0,0,0},

  {0,0,0,0,0,0,0,0,0}

}; 

void draw(){ 

  background(246, 194, 108);

  for(int i=1; i<=9; i++){

    line(50, 50*i, 450, 50*i); 

    line(50*i, 50, 50*i, 450); 

  }

  for(int i=0; i<9; i++){ 

    for(int j=0; j<9; j++){ 

      if( go[i][j]==1){

        fill(0); //1:黑棋

        ellipse(50+j*50, 50+i*50, 40, 40);

        }else if( go[i][j]==2){

          fill(255); 

          ellipse(50+j*50, 50+i*50, 40, 40);

        }

    }

  }

}

 滑鼠點一下會產生黑白棋子

void setup(){

  size(500,500);

}

int [][] go={

  {0,0,0,0,0,0,0,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,1,0,0,0,1,0,0},

  {0,0,0,1,0,1,0,0,0},

  {0,0,0,0,1,0,0,0,0},

  {0,0,0,0,0,0,0,0,0}

}; 

int N=0;

void mousePressed(){

  int j = (mouseX-25)/50;

  int i = (mouseY-25)/50;

  go[i][j] = (N%2==0) ? 1 : 2;  

  N++;

}

void draw(){ 

  background(246, 194, 108); 

  for(int i=1; i<=9; i++){

    line(50, 50*i, 450, 50*i); 

    line(50*i, 50, 50*i, 450); 

  }

  for(int i=0; i<9; i++){ 

    for(int j=0; j<9; j++){ 

      if( go[i][j]==1){

        fill(0); 

        ellipse(50+j*50, 50+i*50, 40, 40);

        }else if( go[i][j]==2){

          fill(255); 

          ellipse(50+j*50, 50+i*50, 40, 40);

        }

    }

  }

}
