I'm looking to make a flashinglight class using a next( ) method. This will change the color from red, yellow and green. I need a counter that increments each time a next( ) message is received and then resets to zero when it reaches 3. The counter needs to access a color array.
Any help will be much appreciated.
This is a different version I came up with but I couldn't figure out how to include a the next method and counter. I have the color array done I think.
import animax.*;
import java.awt.*;
class light
{
public static void main(String args[])
{
AnimationFrame f = new AnimationFrame(500,500);
Container c = f.getContentPane();
Color[] colors =
{
Color.red,
Color.yellow,
Color.green
};
RoundRectGraphic graphic;
Counter counter;
graphic = new RoundRectGraphic(200,200,100,colors,c);
counter = new Counter(0,colors.length - 1);
counter.addGraphic(graphic);
Player player = new Player(500);
player.addListener(counter);
player.play();
}
}

First off, Class names should start with an uppercase letter.
"light" is not a (socially, lol) acceptable Class name.
Second, when posting code on the forums you should weed out
extraneous code and make the code compilable if possible.
Third, use code tags --> [ code] [/ code] (no spaces)
Fourth, consider String[] args over String args[].
A reader can more easily identify the type as an array.
Fifth, consider Color.RED over Color.red.
Constants are typically all uppercase.
Sixth, your Color array is initialized in the main() method which is
a huge mistake. It should be an instance variable of the Light class.
Here, ive cleaned up your code a bit:
import java.awt.*;
public class Light{
public static void main(String[] args){
/*
AnimationFrame f = new AnimationFrame(500,500);
Container c = f.getContentPane();
RoundRectGraphic graphic;
Counter counter;
graphic = new RoundRectGraphic(200,200,100,colors,c);
counter = new Counter(0,colors.length - 1);
counter.addGraphic(graphic);
Player player = new Player(500);
player.addListener(counter);
player.play();
*/
}
public void next(){
}
Color[] colors = {Color.RED, Color.YELLOW, Color.GREEN};
}
no way dude youre so close.
public void next(){
counter ++;
if(counter > 3){
counter = 1;
}
}
int counter;

import java.awt.*;
// import animax.*;
public class Light{
public static void main(String[] args){
/*
AnimationFrame f = new AnimationFrame(500,500);
Container c = f.getContentPane();
RoundRectGraphic graphic;
Counter counter;
graphic = new RoundRectGraphic(200,200,100,colors,c);
counter = new Counter(0,colors.length - 1);
counter.addGraphic(graphic);
Player player = new Player(500);
player.addListener(counter);
player.play();
*/
Light light = new Light();
for(int i = 0; i < 5; i++){
light.next();
System.out.println("Light: " + light.getColor().toString());
}
}
public void next(){
counter ++;
if(counter > 2){
counter = 0;
}
}
public Color getColor(){
return colors[counter];
}
Color[] colors = {Color.RED, Color.YELLOW, Color.GREEN};
int counter = 0;
}
BTW, I made a slip up. The Color array should be static (and possibly final).
static Color[] colors = {Color.RED, Color.YELLOW, Color.GREEN};
then
public Color getColor(){
return Light.colors[counter];
}
