之前的兩篇文章:Java實現兩人五子棋游戲(二) 畫出棋盤;Java實現兩人五子棋游戲(三) 畫出棋子;Java實現兩人五子棋游戲(四) 落子動作的實現,可以點擊查看。
前面我們已經畫好棋盤和棋子,并可以自由落子,且可以判斷棋盤中是否有五連珠。接下來的工作是,每次落子后交換行棋方(即將下一棋子顏色由白->黑或黑->白),并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)。
主模塊Main.java和棋子類Chessman.java不變,我們要對DrawChessBoard.java中的落子函數mousePressed和五連珠判斷函數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函數,使得每次落子后,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函數部分,只要每次都修改chessColor的值即可。
@Override //當用戶按下鼠標按鈕時發生 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!!!!!"); } } }
運行一下
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函數的判斷條件上,加上對Chessman.getColor的顏色判斷
isWin函數代碼
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++) { //橫向查找 if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true) { int matchColor = chessStatus[i][j].getColor(); //向右側查找 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); if(chessStatus[i][j].matchCount==5) { return true; } }else { break; } } } //向左側查找 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+" "+"left count++:"+(i-n)+" "+j+" count:"+chessStatus[i][j].matchCount); 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 if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true) { int matchColor = chessStatus[i][j].getColor(); //向下查找,左上角為坐標原點,y軸正方向向下 for(int n=1;n<=4;n++) { if((j+n>=0)&&(j+n)<=ROWS) { if(chessStatus[i][j+n]!=null&&chessStatus[i][j+n].getPlaced()==true&&chessStatus[i][j+n].getColor()==matchColor) { chessStatus[i][j].matchCount++; System.out.println("pos:"+i+" "+j+" up count++:"+(i)+" "+(j+n)+" count:"+chessStatus[i][j].matchCount); if(chessStatus[i][j].matchCount==5) { return true; } }else { break; } } } //向上查找 for(int n=1;n<=4;n++) { if((j-n>=0)&&(j-n)<=ROWS) { if(chessStatus[i][j-n]!=null&&chessStatus[i][j-n].getPlaced()==true&&chessStatus[i][j-n].getColor()==matchColor) { chessStatus[i][j].matchCount++; System.out.println("pos:"+i+" "+j+" "+"left count++:"+(i)+" "+(j-n)+" count:"+chessStatus[i][j].matchCount); if(chessStatus[i][j].matchCount==5) { return true; } }else { if(chessStatus[i][j-n]!=null) { chessStatus[i][j].matchCount = 1; } break; } } } chessStatus[i][j].matchCount=1;//refresh count } } } //方向:左上右下 for(int i=0;i<ROWS+1;i++) { for(int j=0;j<ROWS+1;j++) { //左上 if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true) { int matchColor = chessStatus[i][j].getColor(); //向下查找,左上角為坐標原點,y軸正方向向下 for(int n=1;n<=4;n++) { if((j-n>=0)&&(j-n)<=ROWS&&(i-n)>=0&&(i-n)<=ROWS) { if(chessStatus[i-n][j-n]!=null&&chessStatus[i-n][j-n].getPlaced()==true&&chessStatus[i-n][j-n].getColor()==matchColor) { chessStatus[i][j].matchCount++; System.out.println("pos:"+i+" "+j+" up count++:"+(i-n)+" "+(j-n)+" count:"+chessStatus[i][j].matchCount); if(chessStatus[i][j].matchCount==5) { return true; } }else { break; } } } //右下 for(int n=1;n<=4;n++) { if((j+n>=0)&&(j+n)<=ROWS&&(i+n)>=0&&(i+n)<=ROWS) { if(chessStatus[i+n][j+n]!=null&&chessStatus[i+n][j+n].getPlaced()==true&&chessStatus[i+n][j+n].getColor()==matchColor) { chessStatus[i][j].matchCount++; System.out.println("pos:"+i+" "+j+" "+"left count++:"+(i+n)+" "+(j+n)+" count:"+chessStatus[i][j].matchCount); if(chessStatus[i][j].matchCount==5) { return true; } }else { if(chessStatus[i+n][j+n]!=null) { chessStatus[i][j].matchCount = 1; } break; } } } chessStatus[i][j].matchCount=1;//refresh count } } } //方向:左下右上 for(int i=0;i<ROWS+1;i++) { for(int j=0;j<ROWS+1;j++) { //左下 if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true) { int matchColor = chessStatus[i][j].getColor(); //向下查找,左上角為坐標原點,y軸正方向向下 for(int n=1;n<=4;n++) { if((j+n>=0)&&(j+n)<=ROWS&&(i-n)>=0&&(i-n)<=ROWS) { if(chessStatus[i-n][j+n]!=null&&chessStatus[i-n][j+n].getPlaced()==true&&chessStatus[i-n][j+n].getColor()==matchColor) { chessStatus[i][j].matchCount++; System.out.println("pos:"+i+" "+j+" up count++:"+(i-n)+" "+(j+n)+" count:"+chessStatus[i][j].matchCount); if(chessStatus[i][j].matchCount==5) { return true; } }else { break; } } } //右上 for(int n=1;n<=4;n++) { if((j-n>=0)&&(j-n)<=ROWS&&(i+n)>=0&&(i+n)<=ROWS) { if(chessStatus[i+n][j-n]!=null&&chessStatus[i+n][j-n].getPlaced()==true&&chessStatus[i+n][j-n].getColor()==matchColor) { chessStatus[i][j].matchCount++; System.out.println("pos:"+i+" "+j+" "+"left count++:"+(i+n)+" "+(j-n)+" count:"+chessStatus[i][j].matchCount); if(chessStatus[i][j].matchCount==5) { return true; } }else { if(chessStatus[i+n][j-n]!=null) { chessStatus[i][j].matchCount = 1; } break; } } } chessStatus[i][j].matchCount=1;//refresh count } } } return false; }
