今天我們來實作判斷棋子與指定格之間是否被阻擋的方法，以及判斷是否被將軍的方法，我們可以將它們寫在ChessmanRulesData當中
大致上分為3個部分，判斷直行、橫行、斜行，其中有無被棋子阻擋
// 判斷是否允許移動棋子

int startCoordinate=0,stopCoordinate=0,startCoordinate2=0,stopCoordinate2=0;

.equals(String.valueOf(playerChessboardData.getStringBoardData(stop).charAt(0)))){
// 判斷直行
for(int i=0;i<coordinate_n.length;i++){
if(String.valueOf(playerChessboardData.getStringBoardData(start).charAt(1)).equals(coordinate_n[i])){

}
if(String.valueOf(playerChessboardData.getStringBoardData(stop).charAt(1)).equals(coordinate_n[i])){

}
}
if(Math.min(startCoordinate,stopCoordinate)+1 == Math.max(startCoordinate,stopCoordinate)){

檢查某格是否被將軍(被其他棋子瞄準)，這裡使用較為原始的作法逐一判斷
