象棋棋盤

用兩個迴圈來畫棋盤 一個負責x 一個負責y

void setup(){

   size(500,700); 

}

void draw(){

   for (int x=50 ; x<=450 ; x+=50){

    line(x,50,x,500);

  }

  for (int y=50 ; y<=500 ; y+=50){

      line(50,y,450,y);

  }

}

劃分楚河漢界

void draw(){

   for (int x=50;x<=450;x+=50){

      line(x,50,x,250);///x的g;上半段

      line(x,300,x,500);///x的下半段

   }

   for (int y=50;y<=500;y+=50){

      line(50,y,450,y); 

   }

   for (int i=0;i<4;i++){

      for (int j=0;j<9;j++){

         text(board[i][j],50+j*50,50+i*50);   

      }

   }

}

上半段放棋子

int [][]board={

   {4,5,3,2,1,2,3,5,4},

   {0,0,0,0,0,0,0,0,0},

   {0,6,0,0,0,0,0,0,0},

   {1,0,1,0,1,0,1,0,1},

};

設定陣列

name[] = {"將","士","象","馬","車","包","卒"};

設定字型

   size(500,700); 

   PFont font = createFont("標楷體",30);

   textFont(font);

   textAlign(CENTER,CENTER);

設定id為board陣列，當id=0時需跳過他

text內的name[ id-1 ]，確保兩個不一樣才不會出錯

for (int i=0;i<4;i++){

      for (int j=0;j<9;j++){

        int id=board[i][j];

        if (id==0) continue;

        text(name[id-1],50+j*50,50+i*50);   

      }

   }

象棋棋子

用ellipse畫圓形 但因為字體不會在格子正中間 所以要偏移(-3)

設陣列[]name2={"帥", "仕", "相","俥" ,"傌", "炮", "兵"};

因為有上下兩層 所以下層編號為負

int [][]board={  {4, 5, 3, 2, 1, 2, 3, 5, 4},  {0, 0, 0, 0, 0, 0, 0, 0, 0},  {0, 6, 0, 0, 0, 0, 0, 6, 0},  {7, 0, 7, 0, 7, 0, 7, 0, 7},  {0, 0, 0, 0, 0, 0, 0, 0, 0},  {0, 0, 0, 0, 0, 0, 0, 0, 0},  {-7, 0,-7, 0,-7, 0,-7, 0,-7},  {0,-6, 0, 0, 0, 0, 0, -6, 0},  {0, 0, 0, 0, 0, 0, 0, 0, 0},  {-4,-5,-3,-2,-1,-2,-3,-5,-4},

};
if else 來判斷id>0 黑字、id <0 紅字

for (int i=0; i<10; i++){

    for (int j=0; j<9; j++){

      int id=board[i][j];

      if (id==0) continue;

      if (id>0) {

        fill(255);

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

        fill(0);///黑色

        text(name[id-1], 50+j*50, 50+i*50-3);

      } else if (id<0) {

        fill(255);

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

        fill(255, 0, 0);///紅色

        text(name2[-id-1], 50+j*50, 50+i*50-3);

      }

    }

  }

滑鼠控制棋子

設定void mousePresssed()

用雙迴圈+dist來判定滑鼠位置

void mousePressed(){

   for (int i=0;i<10;i++){

      for (int j=0;j<0;j++){

         if ( dist(mouseX,mouseY,50+j*50,50+i*50)<20){

            board[i][j]=1; 

         }

      }

   }

}

設定滑鼠放開void mouseReleased()

void mouseReleased(){

   int i=(mouseY+25-50)/50;

   int j=(mouseX+25-50)/50;

   board[i][j]=handchess;

   handchess=0;

}

修改mousePressed() 

void mousePressed(){

   for (int i=0;i<10;i++){

      for (int j=0;j<9;j++){

         if ( dist(mouseX,mouseY,50+j*50,50+i*50)<20){

           handchess=board[i][j];///拿棋子 

           board[i][j]=0; ///清空棋子

         }

      }

   }

}

           hand=board[i][j];
           board[i][j]=0; 
       }

   int i= (mouseY+25-50)/50;
   int j= (mouseX+25-50)/50;
   board[i][j]=hand;
   hand=0;
}

暗棋 ( 修改自原棋盤 )

修改成4*8大小 並修改值

相同void setup() 

因為要將棋子放入格子中間 所以要在void mousePressed()內將值增加25

設定初始全為0

int [][]show={
   {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}
};

設定if else 點即時如果是0就蓋牌 如果不是舊印象棋

f (show[i][j]==0){
         fill(255);
        ellipse( 50+25+j*50, 50+25+i*50, 40, 40);
      }else{
        int id = board[i][j]; 
        drawChess(50+25+j*50, 50+25+i*50, id);
      }
