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。
執行一下@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!!!!!"); } } }
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)
