Ok. Could you make that program? Do you know how?

maybe not completely sure how to do it but I'll look into it

EDIT: How fast would you expect the NXT emulator to run(fps) without the 33% opacity?

Actually, its not an emulator, it just displays the screen of the NXT that is plugged into the computer. It refreshes every 50 ms.

Is it open source? That would make it a lot easier to do otherwise I might be able to do it but I'm not sure how well it would work.

I've only used SDL for video work but it cant capture images from other programs so I have to figure out something else to use. I think I'll use D3D9 because i found a fast way to capture the screen with it. Now if I can convert that to a SDL_Surface with set user boundaries it should work I think

nxtboy, did you actually try the program i wrote?  it doesn't necessarily show EXACTLY 3 frames at EXACTLY 30% opacity every time, it more layers a crapload of them at closer to 40%, but it has a similar effect to what you want I think... since I don't have that emulator i obviously couldn't test the exact values to make it seem grayest...

cooliojazz Could I see the source for your program? I'd just like to look at it to see how you did it. Also I'm trying to learn java so I would like to just read throug some real world programs to see how to make programs

Sure
Code: [Select]
package screenrepeater;

import java.awt.*;
import java.awt.image.*;
import javax.swing.*;

public class ScreenRepeater extends JFrame {
   
    Image background = null;
    boolean bglock = false;

    public static void main(String[] args) {
        ScreenRepeater sr = new ScreenRepeater();
        sr.setSize(200, 200);
        sr.setAlwaysOnTop(true);
        sr.setVisible(true);
        sr.setDefaultCloseOperation(sr.EXIT_ON_CLOSE);
    }
   
    public ScreenRepeater() {
        Thread ssUpdater = new Thread() {
            public void run() {
                AlphaComposite ac = AlphaComposite.getInstance(AlphaComposite.SRC, 0.2f);
                while (true) {
                    long time = System.currentTimeMillis();
                    try {
                        background = new Robot().createScreenCapture(new Rectangle(0, 0, getWidth(), getHeight()));
                        temp = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_4BYTE_ABGR);
                        Graphics2D g2 = (Graphics2D)temp.getGraphics();
                        g2.setComposite(ac);
                        g2.drawImage(background, 0, 0, null);
                        setTitle((1d / (double)(System.currentTimeMillis() - time) * 1000) + "");
                        sleep(1);
                    } catch (Exception ex) {
                        ex.printStackTrace();
                    }
                }
            }
        };
        ssUpdater.start();
        Thread repainter = new Thread() {
            public void run() {
                while (true) {
                    try {
                        repaint();
                        sleep(10);
                    } catch (Exception ex) {
                        ex.printStackTrace();
                    }
                }
            }
        };
        repainter.start();
    }

    BufferedImage temp;
   
    @Override
    public void paint(Graphics g) {
        g.drawImage(temp, 4, 25, null);
    }
}
Just probably don't try to learn good habits off of how I write code... =P

By the way Cooliojazz program would be nice if it captured a fixed regiion of the screen and the captured stuff remained in the middle. Basically some sort of window that creates a motion blur effect on the screen area where it is.

DJ, I was searching for a way to do something like that, but java's screen-capturing utility basically just captures the whole area including windows in your program, so to do something like that, I would have to make the program constantly minimize and un-minimize itself, or constantly toggle between full size and (0,0), or something like that every time i capture the screen, all which take far too long and/or render the program un-interactable (have fun trying to close it now... =P) So i figured just leaving it fixed in the corner would serve the purpose at least...

Yeah, I tried your program, but it doesn't work for what I am doing.
So could you do what I said maybe?
