Thread: Taking Screenshot when Reporting Player

Description: WRites a report for the Player into an XML file and takes a screen shot

Difficulty: 1.

Assumed Knowledge: Knowledge of XML is helpful but not needed

Tested Server: Winterloves.

Files/Classes Modified: Client.java, Misc.java

Procedure
Step 1: Open misc and add inside

Code:

 public static final char validCharacters[] = {
        '_', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm',
        'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '0',
        '1', '2', '3', '4', '5', '6', '7', '8', '9', '!', '@', '#', '$', '%',
        '^', '&', '*', '(', ')', '-', '+', '=', ':', ';', '.', '>', '<', ',',
        '"', '[', ']', '|', '?', '/', '`'};

    public static String longToString(long l) {
        int i = 0;
        char ac[] = new char[12];

        while (l != 0L) {
            long l1 = l;

            l /= 37L;
            ac[11 - i++] = validCharacters[(int) (l1 - l * 37L)];
        }
        return new String(ac, 12 - i, i);
    }

.

Step 2: Next open Client and add

Code:

private ReportScreenShots shots = ReportScreenShots.getInstance();

    /**
     * Writes a log to XML file of the player been Reported
     * @param player the name of the player been reported
     * @param rule the rule the offending player broke
     */
    public final void reportPlayer(final String player, final int rule) {
        final String date = Calendar.DATE + "-" + Calendar.HOUR + "-" + Calendar.MINUTE;
        try {
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();
            Document document = db.newDocument();
            Element em = document.createElement("reported-player");
            em.setAttribute("player", player);
            em.setAttribute("date", date);
            Node reportedBy = document.createTextNode("reported-by");
            reportedBy.setNodeValue(playerName);
            em.appendChild(reportedBy);
            Node ruleBroken = document.createTextNode("rule");
            ruleBroken.setNodeValue(Integer.toString(rule));
            TransformerFactory tFactory = TransformerFactory.newInstance();
            Transformer transformer = tFactory.newTransformer();
            DOMSource source = new DOMSource(document);
            StreamResult result = new StreamResult(new FileOutputStream("./report/Reported-Players.xml"));
            transformer.transform(source, result);
        } catch (ParserConfigurationException pce) {
            System.err.println(pce);
        } catch (TransformerConfigurationException tce) {
            System.err.println(tce);
        } catch (TransformerException te) {
            System.err.println(te);
        } catch (FileNotFoundException e) {
            System.err.println(e);
        }
    }

.

Step 3: Add this with your other Packets:

Code:

case 218:
                final String REPORTED_PLAYER = misc.longToString(inStream.readQWord());
                final int RULE = inStream.readUnsignedByte();
                final String DATE = Calendar.DATE + "-" + Calendar.HOUR + "-" + Calendar.MINUTE;
                try {
                    Toolkit toolkit = Toolkit.getDefaultToolkit();
                    Dimension screenSize = toolkit.getScreenSize();
                    Rectangle screenShape = new Rectangle(0, 0, screenSize.width, screenSize.height);
                    Robot robot = new Robot();
                    BufferedImage image = robot.createScreenCapture(screenShape);
                    File file = new File("/reports/" + REPORTED_PLAYER + " " + DATE + ".png");
                    reportPlayer(REPORTED_PLAYER, RULE);
                    shots.addImage(image, file);                    
                } catch (AWTException awt) {
                    System.err.println(awt);
                }
                break;

Step 4 Finally with you imports add

Code:

import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Calendar;
import javax.imageio.ImageIO;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;

Step 5 add this class as ReportScreenShots

Code:

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import javax.imageio.ImageIO;

public class ReportScreenShots {

    private static ReportScreenShots instance;
    private Map<BufferedImage, File> image = new HashMap<BufferedImage, File>();

    public static ReportScreenShots getInstance() {
        if (instance == null) {
            instance = new ReportScreenShots();
        }
        return instance;
    }

    public Map<BufferedImage, File> getImages() {
        return image;
    }

    public synchronized void addImage(final BufferedImage i, final File f) {
        image.put(i, f);
    }

    public int size() {
        return image.size();
    }

    public void clear() {
        image.clear();
    }
    

    static {
        long start = System.currentTimeMillis();
        ReportScreenShots shots = ReportScreenShots.getInstance();
        if (System.currentTimeMillis() >= 10000000) {
            for (BufferedImage bi : shots.getImages().keySet()) {
                for (File f : shots.getImages().values()) {
                    try {
                        ImageIO.write(bi, "png", f);
                    } catch (IOException e) {
                        System.err.println(e);
                    }
                }
            }
        }
        start = System.currentTimeMillis();
    }
}
