xxdem Posted August 1, 2018 Share Posted August 1, 2018 Nothing special, just some small trivia engine I wrote back in 2012 for my server that I haven't been using since then because I dropped out this feature, so I leave it here if someone finds use for it package drake.aepvp.l2event; import java.io.BufferedReader; import java.io.File; import java.io.FileReader; import java.text.DecimalFormat; import java.util.ArrayList; import l2.ae.pvp.gameserver.ThreadPoolManager; import l2.ae.pvp.gameserver.model.actor.instance.L2PcInstance;

public TriviaEngine() { final File file = new File("./data/trivia.txt"); try (BufferedReader reader = new BufferedReader(new FileReader(file))) { String line; while ((line = reader.readLine()) != null) { final String[] explode = line.split(" - "); _trivias.add(new TriviaTemplate(explode[0], explode[1])); } System.out.println("Succesfully loaded " + _trivias.size() + " Trivia Quizes!"); } catch (final Exception e) { e.printStackTrace(); System.out.println("Unsuccesfully loaded " + _trivias.size() + " Trivia Quizes!"); } if (_trivias.size() > 10) ThreadPoolManager.getInstance().scheduleGeneralAtFixedRate(() -> { TriviaEvent.currentTrivia = new TriviaEvent(); }, 1800000, 1600000 + Rnd.get(400000)); } public static class TriviaEvent { private static TriviaEvent currentTrivia; private static DecimalFormat df = new DecimalFormat("###.##"); private final long startTime = System.currentTimeMillis(); private L2PcInstance closeAnswer; private final TriviaTemplate trivia; public TriviaEvent() { trivia = Util.getRandomItem(_trivias);

if (closeAnswer != null) { Broadcast(closeAnswer.getName() + " wins a small reward for being close enough!"); reward(closeAnswer, 0); } currentTrivia = null; } }, 90000); } private long getTimePassedMillis() { return System.currentTimeMillis() - startTime; } public void check(final L2PcInstance player, String answer) { final long timePassed = getTimePassedMillis(); toTrivia(player, answer, timePassed); answer = answer.toLowerCase(); final String correct = trivia.getAnswer().toLowerCase();

} else fromTrivia(player, "Thats the incorrect answer."); } private void reward(final L2PcInstance player, final long time) { if (time == 0) player.addItem("Trivia", 6320, 1, player, true); else if (time < 4333) player.addItem("Trivia", 6320, 4, player, true); else if (time < 8666) player.addItem("Trivia", 6320, 3, player, true); else if (time < 91000) player.addItem("Trivia", 6320, 2, player, true); } private static void toTrivia(final L2PcInstance player, final String msg, final long timePassed) { final CreatureSay cs = new CreatureSay(0, 2, "->Trivia", "you answered \"" + msg + "\" in " + format(timePassed) + " seconds.");

private final String _answer; public TriviaTemplate(final String question, final String answer) { _question = question; _answer = answer; } public String getQuestion() { return _question; } public String getAnswer() { return _answer; } } public static class InstanceHolder { protected static TriviaEngine instance = new TriviaEngine(); } public static TriviaEngine getInstance() { return InstanceHolder.instance; } } To connect it to your gameserver just put this somewhere in Say2.java if (_type == TELL && "trivia".equalsIgnoreCase(_target)) { final TriviaEvent trivia = TriviaEngine.TriviaEvent.getCurrentTrivia(); if (trivia == null) activeChar.sendMessage("Could not find an active Trivia Event."); else trivia.check(activeChar, _text); return; } Trivia data I was using (I generated this with a java program that was leeching QAs from various sites) https://pastebin.com/Bgei8Tpa Things you have to do by urself: Don't ask the same question within a time period Create your own QA data on trivias.txt Unhardcode the rewards or just edit them impelement a //reload feature The code is tested on live server and worked great, but it is not unit tested and I don't remember if these functions are regex vulnerable 1 Quote Link to comment Share on other sites More sharing options...
BabayG Posted August 1, 2018 Share Posted August 1, 2018 Nice work. Quiz is a nice entertaining feature, but it's very annoying when bots can answer in 0.5 seconds... Quote Link to comment Share on other sites More sharing options...

Obviously xdem is also decent in coding but as he mentioned the code is 6 years ago. I'm referring to both of you. Voluntarily you're just feeding some people like Melron and baksteen who are searching in stackoverflow and Ctrl C Ctrl V code. You are bat man. nothing special Quote Link to comment Share on other sites More sharing options...
