Java实现两人五子棋游戏(三) 画出棋子

作者:v_xchen_v

这篇文章主要为大家详细介绍了Java实现两人五子棋游戏,画出五子棋的棋子,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

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!
