Java實現兩人五子棋遊戲(二) 畫出棋盤

本文為大家分享了java畫出五子棋遊戲棋盤的方法，供大家參考，具體內容如下

棋盤模塊：

畫五子棋棋盤：19條橫線、19條豎線

步驟一：顯示棋盤

我有一張名為chessboard.png的棋盤，位置為根目錄/res/drawable/chessboard/png，現在我要顯示這張圖片。

DrawChessBoard.java

 package xchen.test.simpleGobang; import java.awt.Graphics; import java.awt.Image; import java.awt.Toolkit; import javax.swing.JPanel; public class DrawChessBoard extends JPanel{ public Image boardImg; public DrawChessBoard() { boardImg = Toolkit.getDefaultToolkit().getImage("res/drawable/chessboard.png"); if(boardImg == null) System.err.println("png do not exist"); } @Override protected void paintComponent(Graphics g) { // TODO Auto-generated method stub super.paintComponent(g); int imgWidth = boardImg.getWidth(this); int imgHeight = boardImg.getHeight(this); int FWidth = getWidth(); int FHeight= getHeight(); int x=(FWidth-imgWidth)/2; int y=(FHeight-imgHeight)/2; g.drawImage(boardImg, x, y, null); } }

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.setVisible(true); } }

運行一下

步驟二：為棋盤畫上橫豎線

DrawChessBoard.java

 package xchen.test.simpleGobang; import java.awt.Graphics; import java.awt.Image; import java.awt.Toolkit; import javax.swing.JPanel; public class DrawChessBoard extends JPanel{ public Image boardImg; final private int ROWS = 19; public DrawChessBoard() { boardImg = Toolkit.getDefaultToolkit().getImage("res/drawable/chessboard2.png"); if(boardImg == null) System.err.println("png do not exist"); } @Override protected void paintComponent(Graphics g) { // TODO Auto-generated method stub super.paintComponent(g); int imgWidth = boardImg.getWidth(this); int imgHeight = boardImg.getHeight(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; //畫橫線for(int i=0;i<ROWS;i++) { g.drawLine(x, y+i*span_y, FWidth-x,y+i*span_y); } //畫豎線for(int i=0;i<ROWS;i++) { g.drawLine(x+i*span_x, y, x+i*span_x,FHeight-y); } } }

Main.java不變運行一下

遇到的問題：

1）Eclipse不識別文件夾下的圖片

問題：文件夾中有圖片，但是在Eclipse項目欄中不顯示

解決辦法：在Eclipse中，選中根目錄，F5 refresh，就顯示出來了。
