上一篇文章讲的是Java实现两人五子棋游戏(二) 画出棋盘，已经画好棋盘，接下来要实现控制功能，主要功能：

1）选择棋子

2）画棋子

3）判断胜负

4）交换行棋方

先实现画棋子PART

-------------画棋子代码示例如下--------------

首先，定义一个棋子类，这个类有两个属性，棋子颜色（0-表示黑色，1-表示白色），是否落子（我计划用一个二维数组才存储棋子的落子信息）
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;  } }

接着我们上一部分的画好棋盘的代码部分，新增画棋子的代码，我用两个棋子（一白一黑，分别位于棋盘的【8，8】，【7，7】）来检验画棋子的代码
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;  //画横线  for(int i=0;i<ROWS;i++)  {  g.drawLine(x, y+i*span_y, FWidth-x,y+i*span_y);  }  //画竖线  for(int i=0;i<ROWS;i++)  {  g.drawLine(x+i*span_x, y, x+i*span_x,FHeight-y);  }   //画棋子  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);  }  }  }  } }

主模块代码不变
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标题  setTitle("单机五子棋");   Container containerPane =getContentPane();  containerPane.add(drawChessBoard);  }  public static void main(String[] args) {  Main m = new Main();  m.setSize(800, 800);  m.setVisible(true);  } }

运行一下！
