Java implements two-way Gozi game (7) screen prompt information

Two previous articles: Java implements two Gozi game (two) to draw a chess board; Java implements two Gozi game (three) to draw a chess piece; Java implements two Gozi game (four) to realize the move; Java implements two Gozi game (six) to transform the chess side, you can click to view.

The next function we want to implement is to prompt information on the screen when there are five consecutive beads. Just use showMessageDialog in the isWin part of the mousePressed function.

The mousePressed function code is as follows:

 @Override //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("Legal"); 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)//If it is width/2, two matching values will appear at the middle point{ //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; } } } if(chessStatus[status_x][status_y]==null||chessStatus[status_x][status_y].getPlaced()==false) { 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 win, give a prompt message if(isWin(status_x, status_y, chessStatus)) { System.out.println("WIN!!!"); String winner; //If the next child is white, then this time it is black if(chessColor == WHITE) winner = "Black"; else winner = "Blank"; String mString = String.format("Congratulations, %s WIN!!!", winner); JOptionPane.showMessageDialog(this, mString); } } } }

Run it:

At this point, we have completed the most basic Gozi function. I'll post the complete code below:

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; } }

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 title setTitle("Stand-alone Goji"); Container containerPane =getContentPane(); containerPane.add(drawChessBoard); } public static void main(String[] args) { Main m = new Main(); m.setSize(800, 800); m.setVisible(true); } }
