slowing down movement in an applet.... doesn't have anything to do with the applet.

I need to slow the speed down of my UP keystroke. My code is:

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;

The piece of code that I need to slow down is:

the html code is:

What it does now is it moves the arc to that position... I had it before that it moves by 1 everytime you hit the up key or keep it pushed. But all I want it to do is to move up to the position slowly with one push of the up button.

PS. I didn't know where to post the subject so I know it will probably get moved. Please help!! ^_^

umm...use a timer

if you're in CS class look it up in your book..

when you set up the timer its like this

Timer timer = new Timer(100,new slimeListener());

now the 100 is in milliseconds i beilieve....so the bigger the slower...

then have your other listener start the timer...

hint:

Timer.start() && Timer.stop()

Whats wrong with the code for the timer... where exactly would everything be placed?

public void init ()

{ // Initialize.

setBackground (Color.red); // Background Color.

addKeyListener (new KeyAdapter () // Key Listener.

{ // Keys.
      
      public void keyPressed (KeyEvent ke)
      
      { // Keys Pressed.
        
        if (ke.getKeyCode () == KeyEvent.VK_LEFT) // Left.
        x -= 1;
        repaint ();
        
        if (ke.getKeyCode () == KeyEvent.VK_LEFT && x == 0) // Left Restriction.
        x += 1;
        
        if (ke.getKeyCode () == KeyEvent.VK_RIGHT) // Right.
        x += 1;

ok when you set your timer, it requires two parameters.

1. how fast you want the listener to be called over and over again.

2. the listener of the timer, which has instructions for the timer.

then you have to make a new listener for the timers NEW Listener.

so say you have:

Timer timer = new Timer(100, new timeListener());

public class timeListener implements ActionListener
{
public void ActionPerformed(ActionEvent event)
{
X++;
Y++;
}
}

Then in your keylistener Listener implementation, you would have...

the timer.start() when you press the up key..

and then timer.stop() when you release the up key..

and remember...

when you implement KeyListener...

you have to define the keyPressed(){} keyReleased(){} and keyTyped(){}

and if you want to define what happens when you press or release the up key..

you have to atleast define an empty body for keyTyped(){}

I hope this helps a little bit..

Justin... I'm lost. Sorry... I feel awful that I'm not understanding. I looked in my java book but there wasn't much in it about Timers and there was nothing on how to set start and stop. I set it up the best I could. With what I have... could you give me hints step through step as to what more I have to do. I learn better when I actually do it. Even if you could just point out my problems and comment the areas that I have to add to. It would make more sense to me. Please and thank you.

Or, if u could even write a mini applet using the timer to move say... a square from left to right. That may help.

ok here is the main class which loads the JPanel

here is the actual panel which uses the Timer

import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
 
public class Ball extends JPanel
{
final int WIDTH = 200;
final int HEIGHT = 100;
 
JButton start, stop;
 
int X = 80;
int Y = 50;
 
Timer timer;
 
public Ball()
 
     {
 
       start = new JButton("start");
       start.addActionListener(new ButtonListener());
 
       stop = new JButton("stop");
       stop.addActionListener( new ButtonListener());
 
          add (start);
          add (stop);
 
       timer = new Timer(100, new TimeListener());
 
       setPreferredSize(new Dimension(400,300));
       setBackground(Color.cyan);
 
     }
public void paintComponent(Graphics g)
     {
          super.paintComponent(g);

g.drawRect(X,Y,30,10);
          g.setColor(Color.yellow);
          g.fillRect(X,Y,30,10);
 
     }
 
public class TimeListener implements ActionListener
     {
          public void actionPerformed(ActionEvent event)
               {
                 X++;
                 Y++;
                 repaint();
               }
     }
public class ButtonListener implements ActionListener
      {
          public void actionPerformed (ActionEvent event)
             {
         if (event.getSource() == start)
         timer.start();
 
         if (event.getSource() == stop)
         timer.stop();
             }
      }
}

This should help you better understand how to use the timer...

as you can see, once you hit the start button, its going to start the timer, which in turn, is going to execute X++ and Y++ every 100 milliseconds..

hope this helps you out man

sorry it took so long, it was late when i saw your reply(s)

It compiles fine so I'm guessing everything is in the right spot... but when I push the up key in the applet it will reach y=330 but the slime and the ground continues to flash as if the start is trying to do something. What else do I have to do to get it to work? I'm pretty sure I have my classes right. I don't know where I missed the piece of information?

When it hits 330, it does go down, as long as another key is pushed. But I want it to go down on its own. What would I have to do?

ok i tried your applet, and the up,down,L,R keys don't work, and i saw the

problem

you have to do this....

and if nothing is supposed to happen just define an empty method.

I've used keyAdapter, and it didn't seem to work for me, but even if you

use the key adapter...your supposed to extend it..

Like so:

and for your timers...

have the timer1 start your timer2 when it hits the 330...

so you'll press the up key, then timer1 will start until it hits 330,
then stop, and then timer1 will start the timer2, which will bring it back
up to 440, then timer 2 will stop.(in the timer2 class ofcourse)

so its like this...

hope this helps, and answers your questions...

Ok, Justin... this is what I've done. I have taken out the increasing x an y values and replaced it with more Timers. So the timers work good on start and stop but I have two problems. First: when you push the up key it goes up. But while it goes back down with the Down Timer and if for some mistake (which I want to fix) the controller pushes the up key again it stays on the one y value but can still move left or right, just not up or down. Second problem is this code:

When I would get up to the border of the applet and move diagonally on it, it would stop only when x == 0 or if y was increasing (moving down) but not when it would be moving up. Heres the rest of my code... everythings commented to find easier:

Neverming about the first problem with the Up Key... I fixed it... wasn't thinking straight!

slowing down movement in an applet.... doesn't have anything to do with the applet.
