這篇我們來實作主要移動棋子的方法move()，以及發生移動事件後會使用到的其他方法，接著實作關於士兵升變的方法

move()

首先判斷遊戲是否結束，再通過一些局面的判斷，然後產生棋譜資料，再將修改後的棋盤資料上傳到資料庫，最後初始化本回合暫存的所有變數

public void move(){
        new Thread(() -> {
            // 判斷遊戲是否結束
            if(!isGameFinish()){
                // 如果有王車易位，則修改指定格的棋子
                isCastling();
                // 處理兵的特殊情況
                disposePawn();
                // 產生棋譜資料
                moveData(String.valueOf(playerChessboardData.getStringBoardData(startChessman))
                        ,String.valueOf(playerChessboardData.getStringBoardData(stopChessman)));
                // 判斷是否可升變
                isPromotion();
                // 修改棋盤資料，將目標格棋子改為原起始格棋子，原起始格棋子改為空格
                chessboardData.put(String.valueOf(playerChessboardData.getStringBoardData(stopChessman)),String.valueOf(chessboardData.get(playerChessboardData.getStringBoardData(startChessman))));
                chessboardData.put(String.valueOf(playerChessboardData.getStringBoardData(startChessman)),"  ");

                dbp.uploadData(roomKey,"PawnMove1",pawnMove1);
                // 上傳棋盤資料
                if(isPromotion == false){
                    chessmanMoveData.put(String.valueOf(turn),moveData);
                    dbp.uploadData(roomKey,"ChessmanMoveData",chessmanMoveData);
                    dbp.uploadData(roomKey,"ChessboardData",chessboardData);
                    dbp.uploadData(roomKey,"MoveState","black");
                    // 回合數增加
                    turn += 1;
                    dbp.uploadData(roomKey,"Turn",String.valueOf(turn));
                }
            }

            runOnUiThread(() -> {
                // 清除上回合所有移動資料
                clearData();
            });
        }).start();
    }

isGameFinish()

判斷遊戲是否結束

public boolean isGameFinish(){
        Boolean isGameFinish=false;
        // 如果吃的棋是國王則遊戲結束
        if(chessboardData.get(playerChessboardData.getStringBoardData(stopChessman)).equals("bK")){
            isGameFinish = true;
            dbp.uploadData(roomKey,"WinPlayer","white");

            // 產生棋譜資料
            moveData(String.valueOf(playerChessboardData.getStringBoardData(startChessman))
                    ,String.valueOf(playerChessboardData.getStringBoardData(stopChessman)));
            moveData = moveData + " #";
            // 修改棋盤資料，將目標格棋子改為原起始格棋子，原起始格棋子改為空格
            chessboardData.put(String.valueOf(playerChessboardData.getStringBoardData(stopChessman)),String.valueOf(chessboardData.get(playerChessboardData.getStringBoardData(startChessman))));
            chessboardData.put(String.valueOf(playerChessboardData.getStringBoardData(startChessman)),"  ");
            chessmanMoveData.put(String.valueOf(turn),moveData);
            dbp.uploadData(roomKey,"ChessmanMoveData",chessmanMoveData);
            dbp.uploadData(roomKey,"ChessboardData",chessboardData);
        }
        return isGameFinish;
    }

isCastling()

判斷是否接收到王車易位的指標，若有則同時移動城堡

public void isCastling(){
        if(castling.equals("leftCastling")){
            chessboardData.put("d1","wR");
            chessboardData.put("a1","  ");
        }else if(castling.equals("rightCastling")){
            chessboardData.put("f1","wR");
            chessboardData.put("h1","  ");
        }
    }

disposePawn()

處理士兵的特殊走法

public void disposePawn(){
        // 如果可吃過路兵，將對方兵變為空格
        if(!(inPassing.equals(""))){
            chessboardData.put(inPassing,"  ");
        }
        // 將自己的兵標記清除
        for(int i=1;i<=8;i++){
            pawnMove1.put(coordinate_a[i]+"4",false);
        }
        // 如果有兵起始走2格，將該兵做標記
        if(!(moveTwoStep.equals(""))){
            pawnMove1.put(moveTwoStep,true);
        }
    }

moveData()

產生棋譜資料

public void moveData(String start,String stop){
        // moveData = 棋種 + 起始座標
        moveData = chessboardData.get(start).toString().charAt(1) + start;
        // 判斷是移動到空格還是吃棋
        if(chessboardData.get(stop).equals("  ")){
            moveData = moveData + " > ";
        } else if (String.valueOf(chessboardData.get(stop).toString().charAt(0)).equals("b")) {
            moveData = moveData + " X ";
        }
        // moveData = 棋種 + 起始座標 X,> 目標座標
        moveData = moveData + stop;
    }

isPromotion()

判斷士兵是否可進行升變，若可以則跳出選擇升變的dialog

public void isPromotion(){
        // 判斷是否有兵移動到最底橫列
        if(chessboardData.get(String.valueOf(playerChessboardData.getStringBoardData(startChessman))).equals("wP")
                && stopChessman/8==0){
            isPromotion = true;
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // 顯示升變選擇
                    showPromotionDialog(stopChessman);
                }
            });
        }
    }

clearData()

初始化暫存的變數

public void clearData(){
        startChessman = 99;
        stopChessman = 99;
        castling = "";
        moveTwoStep = "";
        inPassing = "";
        getCount=0;
        isPromotion = false;
        for(int i=0;i<64;i++){
            chessmanSelect.get(i).setBackgroundResource(R.drawable.blank);
        }
    }

升變

升變是士兵的特殊走法之一，我們在這邊實作簡單的對話框來實現讓使用者選擇欲升變的棋種

  • showPromotionDialog()
public void showPromotionDialog(int p){
        // 創建升變Dialog並設置自定義布局
        Dialog dialog = new Dialog(this);
        dialog.setContentView(R.layout.white_promotion_dialog_item);
        // 獲取自定義布局中的UI元素
        TextView tv_q = dialog.findViewById(R.id.tv_q);
        TextView tv_b = dialog.findViewById(R.id.tv_b);
        TextView tv_n = dialog.findViewById(R.id.tv_n);
        TextView tv_r = dialog.findViewById(R.id.tv_r);
        Button btn_promotion_q = dialog.findViewById(R.id.btn_promotion_q);
        Button btn_promotion_b = dialog.findViewById(R.id.btn_promotion_b);
        Button btn_promotion_n = dialog.findViewById(R.id.btn_promotion_n);
        Button btn_promotion_r = dialog.findViewById(R.id.btn_promotion_r);
        Button btn_submit = dialog.findViewById(R.id.btn_submit);

        promotion = "";
        btn_submit.setEnabled(false);
        btn_submit.setBackgroundResource(R.drawable.whitebackground_grayline);
        btn_promotion_q.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                tv_q.setBackgroundResource(R.drawable.blank);
                tv_b.setBackgroundResource(R.drawable.blank);
                tv_n.setBackgroundResource(R.drawable.blank);

                if(promotion.equals("Q")){
                    promotion="";
                }else{
                    promotion="Q";
                    tv_q.setBackgroundResource(R.drawable.redline);
                }
                if(promotion.equals("")){
                    btn_submit.setEnabled(false);
                    btn_submit.setBackgroundResource(R.drawable.whitebackground_grayline);
                }else{

                    btn_submit.setBackgroundResource(R.drawable.redbackground_blackline);
                }
            }
        });
        btn_promotion_b.setOnClickListener(new View.OnClickListener() {
            @Override

                    promotion="B";
                    tv_b.setBackgroundResource(R.drawable.redline);
                }
                if(promotion.equals("")){
                    btn_submit.setEnabled(false);
