Timer Class to flicker the color of the numbers
i have wrote most of my sudoku code including the gui. i need help flickering two colors for a solved row, col, or 3*3 box. i have a writeNumber method that will probably make the new method easier(it takes the logical x/y coordinates and translate them into phyiscal coordinates.). i am very new to the timer class and i know i need it for this feature. i also think i need another method to detect a row,col, or the box being solve.
Here is the writeNumber method:
private void writeNumber(Graphics g, byte x, byte y, String number, Color color)
{
final int factor = 40;
g.setFont(new Font("Serif", Font.BOLD, 30));
g.setColor(color);
if (!number.equals(""))
{
byte temp = Byte.parseByte(number);
g.drawString(String.valueOf(temp), 12 + x * factor, 30 + y * factor);
}
}

Code:
import java.util.*;
public class TimerExample {
private Timer timer;
public TimerExample() {
timer = new Timer();
timer.schedule(new TimerTask() {
public void run() {
//Add here what you want to do everytime
}
//The timer will run the task after 0ms and will repeat after each 500ms
}, 0, 500);
}
}
EDIT: to terminate all timer tasks use
Re: Timer Class to flicker the color of the numbers
How would i incorporate the flickering of the colors into my (Sudoku)gameboard.
Re: Timer Class to flicker the color of the numbers
Code:
import java.util.*;
import java.util.Timer;
import java.awt.*;
import javax.swing.*;
public class SudokuGame
extends JFrame {
private Timer timer;
private Color color;
public SudokuGame() {
timer = new Timer();
timer.schedule(new TimerTask() {
public void run() {
if (color.equals(Color.BLUE)) {
color = Color.RED;
}
else {
color = Color.BLUE;
}
repaint();
}
//The timer will run the task after 0ms and will repeat after each 500ms
}, 0, 500);
timer.cancel();
}
}
This code switches between Blue and Red every 500ms, override the paint(Graphics g) and use the g.setColor(color); before painting
Re: Timer Class to flicker the color of the numbers
A Timer object is probably the best route to go. You can always use Thread objects, but the coding and running of the program can get quit messy when you want everything to flow smoothly. Use CJ's example and you should be fine.
