這篇文章主要為大家詳細(xì)介紹了Java實(shí)現(xiàn)兩人五子棋游戲，畫(huà)出五子棋的棋子，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

上一篇文章講的是Java實(shí)現(xiàn)兩人五子棋游戲(二) 畫(huà)出棋盤(pán)，已經(jīng)畫(huà)好棋盤(pán)，接下來(lái)要實(shí)現(xiàn)控制功能，主要功能：

1）選擇棋子

2）畫(huà)棋子

3）判斷勝負(fù)

4）交換行棋方

先實(shí)現(xiàn)畫(huà)棋子PART

-------------畫(huà)棋子代碼示例如下--------------

首先，定義一個(gè)棋子類(lèi)，這個(gè)類(lèi)有兩個(gè)屬性，棋子顏色（0-表示黑色，1-表示白色），是否落子（我計(jì)劃用一個(gè)二維數(shù)組才存儲(chǔ)棋子的落子信息）
Chessman.java

package xchen.test.simpleGobang; 
 
public class Chessman { 
 private int color;//1-white，0-black 
 private boolean placed = false; 
 
 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; 
 } 
}

接著我們上一部分的畫(huà)好棋盤(pán)的代碼部分，新增畫(huà)棋子的代碼，我用兩個(gè)棋子（一白一黑，分別位于棋盤(pán)的【8，8】，【7，7】）來(lái)檢驗(yàn)畫(huà)棋子的代碼
DrawChessBoard.java

package xchen.test.simpleGobang; 
 
import java.awt.Graphics; 
import java.awt.Graphics2D; 
import java.awt.RadialGradientPaint; 
import java.awt.Image; 
import java.awt.Toolkit; 
import java.awt.Color; 
import javax.swing.JPanel; 
 
public class DrawChessBoard extends JPanel{ 
 final static int BLACK=0; 
 final static int WHITE=1; 
 public int chessColor = BLACK; 
 
 public Image boardImg; 
 final private int ROWS = 19; 
 Chessman[][] chessStatus=new Chessman[ROWS][ROWS]; 
 
 public DrawChessBoard() { 
 boardImg = Toolkit.getDefaultToolkit().getImage("res/drawable/chessboard2.png"); 
 if(boardImg == null) 
 System.err.println("png do not exist"); 
 
 //test draw chessman part simple 
 Chessman chessman=new Chessman(0, true); 
 chessStatus[7][7]=chessman; 
 Chessman chessman2 = new Chessman(1, true); 
 chessStatus[8][8]=chessman2; 
 //test draw chessman part simple 
 } 
 @Override 
 protected void paintComponent(Graphics g) { 
 // TODO Auto-generated method stub 
 super.paintComponent(g); 
 
 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; 
 g.drawImage(boardImg, x, y, null); 
 
 int margin = x; 
 int span_x=imgWidth/ROWS; 
 int span_y=imgHeight/ROWS; 
 //畫(huà)橫線 
 for(int i=0;i<ROWS;i++) 
 { 
 g.drawLine(x, y+i*span_y, FWidth-x,y+i*span_y); 
 } 
 //畫(huà)豎線 
 for(int i=0;i<ROWS;i++) 
 { 
 g.drawLine(x+i*span_x, y, x+i*span_x,FHeight-y); 
 } 
 
 //畫(huà)棋子 
 for(int i=0;i<ROWS;i++) 
 { 
 for(int j=0;j<ROWS;j++) 
 { 
 if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true) 
 { 
 System.out.println("draw chessman "+i+" "+j); 
 int pos_x=x+i*span_x; 
 int pos_y=y+j*span_y; 
 int chessman_width=20; 
 float radius_b=20; 
 float radius_w=50; 
 float[] fractions = new float[]{0f,1f}; 
 java.awt.Color[] colors_b = new java.awt.Color[]{Color.BLACK,Color.WHITE}; 
 Color[] colors_w = new Color[]{Color.WHITE,Color.BLACK}; 
 RadialGradientPaint paint; 
 if(chessStatus[i][j].getColor()==1) 
 { 
 System.out.println("draw white chess"); 
 paint = new RadialGradientPaint(pos_x-chessman_width/2f, pos_y-chessman_width/2f, radius_w*2, fractions, colors_w); 
 }else{ 
 System.out.println("draw black chess"); 
 paint = new RadialGradientPaint(pos_x-chessman_width/2f, pos_y-chessman_width/2f, radius_b*2, fractions, colors_b); 
 } 
 ((Graphics2D)g).setPaint(paint); 
 
 ((Graphics2D)g).fillOval(pos_x-chessman_width/2,pos_y-chessman_width/2,chessman_width,chessman_width); 
 } 
 } 
 } 
 } 
}

主模塊代碼不變
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(biāo)題 
 setTitle("單機(jī)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); 
 } 
}

運(yùn)行一下！
