Java實現一個簡單的兩人五子棋遊戲(六) 行棋方變換

1)選擇棋子

✔️

2)畫棋子

✔️

3)判斷勝負

✔️

4)交換行棋方

目標

前面我們已經畫好棋盤和棋子,並可以自由落子,且可以判斷棋盤中是否有五連珠。接下來的工作是,每次落子後交換行棋方(即將下一棋子顏色由白->黑或黑->白),並將勝出判斷增加顏色判斷條件(棋盤上存在五連珠->棋盤上存在同色的五連珠)。


主模組Main.java和棋子類Chessman.java不變,我們要對DrawChessBoard.java中的落子函式mousePressed和五連珠判斷函式isWin做一下調整。

Main.java

package xchen.test.simpleGobang;

import java.awt.Container;
import javax.swing.JFrame;

import xchen.test.simpleGobang.DrawChessBoard;

public class Main extends JFrame{
	private DrawChessBoard drawChessBoard;
	public Main() {		
		drawChessBoard = new DrawChessBoard();
		
		//Frame標題
		setTitle("單機五子棋");
		
		Container containerPane =getContentPane();
		containerPane.add(drawChessBoard);		
	}
	public static void main(String[] args) {
		Main m = new Main();
		m.setSize(800, 800);
		m.setVisible(true);
	}
}

Chessman.java
package xchen.test.simpleGobang;

public class Chessman {
	private int color;//1-white,0-black
	private boolean placed = false;
	int matchCount = 1;
	
	public Chessman(int color,boolean placed){
		this.color=color;
		this.placed=placed;
	}
	
	public boolean getPlaced() {
		return placed;
	}

	public void setPlaced(boolean placed) {
		this.placed = placed;
	}

	public int getColor() {
		return color;
	}

	public void setColor(int color) {
		this.color = color;
	}
}

第一步,修改mousePressed函式,使得每次落子後,都將行棋方讓給對家(即每次落子都改變棋子顏色)

DrawChessBoard.java中的mousePressed函式部分,只要每次都修改chessColor的值即可。

	@Override
	//當用戶按下滑鼠按鈕時發生
	public void mousePressed(MouseEvent e) {
		int point_x=e.getX();
		int point_y=e.getY();

		int imgWidth = boardImg.getHeight(this);
		int imgHeight = boardImg.getWidth(this);
		int FWidth = getWidth();
		int FHeight= getHeight();

		int x=(FWidth-imgWidth)/2;
		int y=(FHeight-imgHeight)/2;

		int span_x=imgWidth/ROWS;
		int span_y=imgHeight/ROWS;

		//System.out.println("press");
		int status_x = 0;
		int status_y = 0;
		if(point_x>=x && point_x<=x+imgWidth && point_y>=y && point_y <= y+imgHeight)
		{
			//System.out.println("合法");
			for(int i=0;i<ROWS+1;i++)
			{
				if(point_x>=x-chessman_width/2+1+i*span_x)
				{
					if(point_x<=x+chessman_width/2-1+i*span_x)//如果是width/2會在中間點出現兩個匹配值
					{
						//System.out.println("point x "+i+" "+point_x+" "+(x-chessman_width/2+i*span_x)+" "+(x+chessman_width/2+i*span_x));
						status_x = i;
					}
				}
			}
			for(int i=0;i<ROWS+1;i++)
			{
				if(point_y>=y-chessman_width/2+1+i*span_y)
				{
					if(point_y <= y+chessman_width/2-1+i*span_y)
					{
						//System.out.println("point y "+i+" "+point_y+" "+(y-chessman_width/2+1+i*span_y)+" "+(y+chessman_width/2-1+i*span_y));
						status_y = i;
					}
				}
			}
			
			Chessman chessman = new Chessman(chessColor, true);
			chessStatus[status_x][status_y]=chessman;
			System.out.println("chess color:"+chessColor);
			if(chessColor==BLACK)
			{
				chessColor = WHITE;
			}else {
				chessColor = BLACK;
			}
			repaint();
			if(isWin(status_x, status_y, chessStatus))
			{
				System.out.println("WIN!!!!!");
			}
		}
	}
執行一下


第二步,將勝出判斷增加顏色判斷條件(棋盤上存在五連珠->棋盤上存在同色的五連珠)

在isWin函式的判斷條件上,加上對Chessman.getColor的顏色判斷

isWin函式程式碼

	boolean isWin(int point_x,int point_y,Chessman[][] cm)
	{	
		for(int i=0;i<ROWS+1;i++)
		{
			for(int j=0;j<ROWS+1;j++)
			{
				//橫向查詢
				if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true)
				{
					int matchColor = chessStatus[i][j].getColor();
					//向右側查詢
					for(int n=1;n<=4;n++)
					{
						if((i+n>=0)&&(i+n)<=ROWS)
						{
							if(chessStatus[i+n][j]!=null&&chessStatus[i+n][j].getPlaced()==true&&chessStatus[i+n][j].getColor()==matchColor)
							{
								chessStatus[i][j].matchCount++;
								System.out.println("pos:"+i+" "+j+" right count++:"+(i+n)+" "+j+" count:"+chessStatus[i][j].matchCount);

						}
					}
					//向左側查詢
					for(int n=1;n<=4;n++)
					{

						{

								if(chessStatus[i][j].matchCount==5)
								{
									return true;
								}
							}else
							{
								if(chessStatus[i-n][j]!=null)
								{
									chessStatus[i][j].matchCount = 1;
								}
								break;
							}
						}
					}
					chessStatus[i][j].matchCount=1;//refresh count
				}
			}
		}

		for(int i=0;i<ROWS+1;i++)
		{
			for(int j=0;j<ROWS+1;j++)
			{
				//縱向
