Thread: Make A Text Blinking Effect

Hello! In carrying out my little game I made a panel "Winner" in which I have two JButton plus I would like to add a blinking text to indicate the victory of the player("You win!").
Currently this text is static, designed by the function drawImage.
How can I make it "flashing" maybe alternating the vision of the text (which I present in two different colors)?

This is the panel of the winner after the game :

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedWriter;
import java.io.FileNotFoundException;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
 
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.Timer;
 
import core.GameManager;
import core.Score;
import world.World;
 
public class Winner extends JPanel{ 
 
	public static ImageProvider imageP;
	public MainFrame mainFrame;
	public Image gameOver;
	public World world;
	public Insets inserts;
	public GamePanel gamePanel;
	public GameManager gameManager;
	public final List<Score> scores = new ArrayList<Score>();
	public ScorePanel sPanel;
	public boolean change=false;
	private Timer timer;
 
	public Winner(final ImageProvider imageP, MainFrame mainframe, GamePanel gamePanel,   World world, GameManager gameManager,ScorePanel sPanel) throws FileNotFoundException {
	this.setLayout(null);
	this.mainFrame = mainframe;
	this.gameManager = gameManager;
	this.imageP = imageP;
	this.world = world;
	this.gamePanel = gamePanel;
	this.sPanel = sPanel;
	inserts = this.getInsets();
 
	new Timer(1000, new ActionListener() {	
	@Override
	public void actionPerformed(ActionEvent e) {
            change=true;
	    if(change){
	    imageP.getWin();
	    }
	    change=false;
	    imageP.getWinY();				
	    timer.start();		
	}
	});
}
 
        @Override
	protected void paintComponent(Graphics g) {
	super.paintComponent(g);
	g.drawImage(imageP.getBackground(), 0, 0, getWidth(), getHeight(), this);
	}

Basically, the timer should alternate every second before imageP.getWin() and then imageP.getWinY().
Unfortunately, it is the first time I use the timer and don't know how to insert the repaint();
Could you help me to modify my code?

Some thoughts after looking at your actionPerformed() method:

1. 'change' will always be true at the beginning of the body of the method. consider using the ternary operator to flip change's value.
2. starting the timer inside the actionPerformed() method won't work.
2.A the Timer construction you've used is ANONYMOUS, so does not provide an instance 'timer' to start
3. this is where the repaint() method should be called

Simplify. Break out some separate classes and use those as your ActionListener and JPanel. (Perhaps class Winner does that for the JPanel part, but it's hard to tell with what you've posted.)

Thanks for the tips. Unfortunately it is not easy to understand the problem. I can say that this class is activated once the player reaches a maximum score in the GamePanel. Then you will have the panel Winner who will have a background (as you can see from the paintComponent ()) and more this text, "You win."
"You Win!" Is an Image of two different colors that I would like to draw using drawImage.
You should draw a picture first and then the other at regular intervals (simulating a "flashing")

You can make it as complicated as you want, for real or in your imagination, and achieving the blinking effect boils down the same, relatively simple bit of code: a timer that triggers an actionPerformed() method that calls a repaint() on the desired component. The variation that defines the effect can be done in the actionPerformed() method, in the component's paintComponent() method, or in a combination of both.
