3. 实现步骤

3.1 棋子类实现(ChessPiece.java)

package com.example.militarychess;public class ChessPiece {public static final int RED = 0;public static final int BLUE = 1;// 棋子类型public static final int FLAG = 0;       // 军旗public static final int MINE = 1;       // 地雷public static final int BOMB = 2;       // 炸弹public static final int MARSHAL = 3;    // 司令public static final int GENERAL = 4;    // 军长public static final int DIVISION = 5;   // 师长public static final int BRIGADE = 6;    // 旅长public static final int REGIMENT = 7;   // 团长public static final int BATTALION = 8;  // 营长public static final int COMPANY = 9;    // 连长public static final int PLATOON = 10;   // 排长public static final int ENGINEER = 11;  // 工兵private int type;    // 棋子类型private int color;   // 棋子颜色private int row;     // 行private int col;     // 列private boolean visible = false; // 是否可见public ChessPiece(int type, int color, int row, int col) {this.type = type;this.color = color;this.row = row;this.col = col;}// getter和setter方法public int getType() { return type; }public int getColor() { return color; }public int getRow() { return row; }public void setRow(int row) { this.row = row; }public int getCol() { return col; }public void setCol(int col) { this.col = col; }public boolean isVisible() { return visible; }public void setVisible(boolean visible) { this.visible = visible; }// 获取棋子名称public String getName() {String[] names = {"军旗", "地雷", "炸弹", "司令", "军长", "师长", "旅长", "团长", "营长", "连长", "排长", "工兵"};return names[type];}// 获取棋子简称public String getShortName() {String[] names = {"旗", "雷", "弹", "司", "军", "师", "旅", "团", "营", "连", "排", "工"};return names[type];}
}

3.2 游戏视图实现(GameView.java)

ChessPiece.BLUE : ChessPiece.RED;selectedPiece = null;invalidate();}public void resetGame() {initPieces();currentPlayer = ChessPiece.RED;selectedPiece = null;invalidate();}
}

3.3 主界面实现(MainAbilitySlice.java)

package com.example.militarychess;import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.*;
import ohos.agp.window.dialog.ToastDialog;public class MainAbilitySlice extends AbilitySlice {private GameView gameView;private Text statusText;@Overridepublic void onStart(Intent intent) {super.onStart(intent);DirectionalLayout layout = new DirectionalLayout(this);layout.setOrientation(DirectionalLayout.VERTICAL);// 状态文本statusText = new Text(this);statusText.setText("当前回合: 红方");statusText.setTextSize(50);statusText.setPadding(10, 10, 10, 10);// 游戏视图gameView = new GameView(this);// 按钮布局DirectionalLayout buttonLayout = new DirectionalLayout(this);buttonLayout.setOrientation(DirectionalLayout.HORIZONTAL);buttonLayout.setPadding(10, 10, 10, 10);// 重新开始按钮Button resetButton = new Button(this);resetButton.setText("重新开始");resetButton.setClickedListener(component -> gameView.resetGame());// 规则说明按钮Button ruleButton = new Button(this);ruleButton.setText("游戏规则");ruleButton.setClickedListener(component -> showRules());buttonLayout.addComponent(resetButton);buttonLayout.addComponent(ruleButton);layout.addComponent(statusText);layout.addComponent(gameView);layout.addComponent(buttonLayout);super.setUIContent(layout);}private void showRules() {new ToastDialog(this).setText("军棋规则:\n1. 工兵可以挖地雷\n2. 炸弹可以与任何棋子同归于尽\n3. 大本营内的棋子不能移动").show();}
}

3.4 布局文件(ability_main.xml)

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayoutxmlns:ohos="http://schemas.huawei.com/res/ohos"ohos:width="match_parent"ohos:height="match_parent"ohos:orientation="vertical"ohos:background_element="#F5F5F5"><Textohos:id="$+id:status_text"ohos:width="match_parent"ohos:height="50vp"ohos:text="当前回合: 红方"ohos:text_size="20fp"ohos:text_color="#FF0000"ohos:padding="10vp"ohos:margin="5vp"ohos:background_element="#FFFFFF"/><com.example.militarychess.GameViewohos:id="$+id:game_view"ohos:width="match_parent"ohos:height="0vp"ohos:weight="1"ohos:margin="5vp"ohos:background_element="#FFFFFF"/><DirectionalLayoutohos:id="$+id:button_layout"ohos:width="match_parent"ohos:height="wrap_content"ohos:orientation="horizontal"ohos:padding="10vp"ohos:margin="5vp"ohos:background_element="#FFFFFF"><Buttonohos:id="$+id:reset_button"ohos:width="0vp"ohos:height="50vp"ohos:weight="1"ohos:text="重新开始"ohos:text_size="16fp"ohos:margin="5vp"/><Buttonohos:id="$+id:rule_button"ohos:width="0vp"ohos:height="50vp"ohos:weight="1"ohos:text="游戏规则"ohos:text_size="16fp"ohos:margin="5vp"/></DirectionalLayout>
</DirectionalLayout>

4. 游戏规则实现要点

4.1 棋子移动规则

private boolean isValidMove(ChessPiece piece, int toRow, int toCol) {// 1. 检查目标位置是否合法if (toRow < 0 || toRow >= ROWS || toCol < 0 || toCol >= COLS) {return false;}// 2. 检查是否是大本营(不能移动)if (isHeadquarters(piece.getRow(), piece.getCol())) {return false;}// 3. 铁路线移动规则if (isRailway(piece.getRow(), piece.getCol())) {// 铁路线上可以任意距离直线移动return canMoveOnRailway(piece, toRow, toCol);}// 4. 普通移动规则(一步一格)int rowDiff = Math.abs(toRow - piece.getRow());int colDiff = Math.abs(toCol - piece.getCol());return (rowDiff == 1 && colDiff == 0) || (rowDiff == 0 && colDiff == 1);
}

4.2 吃子规则

private boolean canEat(ChessPiece attacker, ChessPiece defender) {// 1. 炸弹可以和任何棋子同归于尽if (attacker.getType() == ChessPiece.BOMB || defender.getType() == ChessPiece.BOMB) {return true;}// 2. 工兵可以挖地雷if (attacker.getType() == ChessPiece.ENGINEER && defender.getType() == ChessPiece.MINE) {return true;}// 3. 地雷只能被工兵挖if (defender.getType() == ChessPiece.MINE) {return false;}// 4. 军旗不能被移动if (defender.getType() == ChessPiece.FLAG) {return false;}// 5. 普通棋子比较大小return attacker.getType() <= defender.getType();
}

5. 特殊功能实现

5.1 行营保护

private boolean isCamp(int row, int col) {// 定义行营位置int[][] camps = {{1, 1}, {1, 3}, {3, 1}, {3, 3}, {8, 1}, {8, 3}, {10, 1}, {10, 3}};for (int[] camp : camps) {if (camp[0] == row && camp[1] == col) {return true;}}return false;
}

5.2 铁路线移动

private boolean canMoveOnRailway(ChessPiece piece, int toRow, int toCol) {// 检查是否在同一条铁路线上if (piece.getRow() != toRow && piece.getCol() != toCol) {return false;}// 检查路径上是否有其他棋子阻挡if (piece.getRow() == toRow) {int minCol = Math.min(piece.getCol(), toCol);int maxCol = Math.max(piece.getCol(), toCol);for (int col = minCol + 1; col < maxCol; col++) {if (getPieceAt(piece.getRow(), col) != null) {return false;}}} else {int minRow = Math.min(piece.getRow(), toRow);int maxRow = Math.max(piece.getRow(), toRow);for (int row = minRow + 1; row < maxRow; row++) {if (getPieceAt(row, piece.getCol()) != null) {return false;}}}return true;
}
