1.畫出棋盤

void setup()

{

  size(500,500);

}

void draw()

{

  background(253,236,180);

  for(int i=0;i<9;i++){

    line(50,50+50*i, 450,50+50*i);//畫直線

    line(50+50*i,50, 50+50*i,450);//畫橫線

}

2.設定方格矩陣和旗子

▲矩陣

int[][]go = {

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0},

  {0,0,0,0,0,0,0,0,0}};

▲棋子

for(int i=0;i<9;i++){

  for(int j=0; j<9;j++){

    if(go[i][j]==1){

      int x=50+50*j,y=50+50*i;

      fill(255);ellipse(x,y,40,40);//畫圓

      }else if(go[i][j]==2){

        int x=50+50*j,y=50+50*i;

        fill(0);ellipse(x,y,40,40);

      }

    }

  }

3.建立黑白棋和清除鍵

void mousePressed(){

  int j = (mouseX-25)/50;//判斷點擊位置

  int i = (mouseY-25)/50;

  if(mouseButton==LEFT)go[i][j]=1;//下白棋

  if(mouseButton==RIGHT)go[i][j]=2;//下黑棋

  if(mouseButton==CENTER)go[i][j]=0;//清除棋子
