Well, it totally depends of the "idea" of your mod.

 

A captcha system have more reasons to exist on the entrance of any player (enterWorld.java) than in the DoDie method of any L2Attackable monster/summon/player.

 

Considering your captcha thing is *CURRENTLY* :

- generating correctly a random code, and make the association code/input text (well your code is primitive, but it seems to work);

- sending a window at the death of a player (killing anything other than a player show a NPE atm, from what I think);

- punishing the player if the code is wrong;

 

The only thing you have to do is to remove all the code from L2Attackable and edit it for EnterWorld. Basically your code fits for EnterWorld, as it misses all good instances checks, and enterWorld is "made" for players only.

 

------

 

Revert back your code in L2Attackable then

 

	/**
 * Kill the L2Attackable (the corpse disappeared after 7 seconds), distribute rewards (EXP, SP, Drops...) and notify Quest Engine.
 *
 * Actions:
 * Distribute Exp and SP rewards to L2PcInstance (including Summon owner) that hit the L2Attackable and to their Party members
 * Notify the Quest Engine of the L2Attackable death if necessary
 * Kill the L2NpcInstance (the corpse disappeared after 7 seconds)
 *
 * Caution: This method DOESN'T GIVE rewards to L2PetInstance
 *
 * @param killer The L2Character that has killed the L2Attackable
 */
@Override
public boolean doDie(L2Character killer)
{
	// Kill the L2NpcInstance (the corpse disappeared after 7 seconds)
	if (!super.doDie(killer))
		return false;

	// Notify the Quest Engine of the L2Attackable death if necessary
	try
	{
		L2PcInstance player = null;

		if (killer != null)
			player = killer.getActingPlayer();

		if (player != null)
		{
			if (getTemplate().getEventQuests(Quest.QuestEventType.ON_KILL) != null)
				for (Quest quest: getTemplate().getEventQuests(Quest.QuestEventType.ON_KILL))
					ThreadPoolManager.getInstance().scheduleEffect(new OnKillNotifyTask(this, quest, player, killer instanceof L2Summon), _onKillDelay);
		}
	}
	catch (Exception e) { _log.log(Level.SEVERE, "", e); }
	return true;
}

 

And in enterworld.java, find the good place to put (around the end, as enterWorld initializes many things) - I perhaps made errors, I just edited with notepad and didn't check synthax/logic :

 

if (Config.ENABLE_ANTIBOT_SYSTEM)
{
private static int AntiBotKills = 0;
private static int Change = 0;
int AntiBotKillsCheck = (Config.ANTIBOT_KILLS_CHECK);
NpcHtmlMessage npcHtmlMessage = new NpcHtmlMessage(0);

Change = Rnd.get(8);
AntiBotKills++;

if (AntiBotKills >= AntiBotKillsCheck)
{
	killer.setIsParalyzed(true);
	AntiBotKills = 0;
	switch(Change)

}

 

I didn't test your mechanism, so don't tell it doesn't works (this is your system if I didn't fock the c/p :D), and I don't know how the player isn't supposed to be de-paralized, I guess the voiced command got it.

 

killer have to be replaced to activeChar, imports have surely to be corrected, and such.

I didn't test your mechanism, so don't tell it doesn't works (this is your system if I didn't fock the c/p :D), and I don't know how the player isn't supposed to be de-paralized, I guess the voiced command got it.

 

killer have to be replaced to activeChar, imports have surely to be corrected, and such.

Well, it totally depends of the "idea" of your mod.

 

A captcha system have more reasons to exist on the entrance of any player (enterWorld.java) than in the DoDie method of any L2Attackable monster/summon/player.

 

Considering your captcha thing is *CURRENTLY* :

- generating correctly a random code, and make the association code/input text (well your code is primitive, but it seems to work);

- sending a window at the death of a player (killing anything other than a player show a NPE atm, from what I think);

- punishing the player if the code is wrong;

 

The only thing you have to do is to remove all the code from L2Attackable and edit it for EnterWorld. Basically your code fits for EnterWorld, as it misses all good instances checks, and enterWorld is "made" for players only.

 

------

 

Revert back your code in L2Attackable then

 

	/**
 * Kill the L2Attackable (the corpse disappeared after 7 seconds), distribute rewards (EXP, SP, Drops...) and notify Quest Engine.
 *
 * Actions:
 * Distribute Exp and SP rewards to L2PcInstance (including Summon owner) that hit the L2Attackable and to their Party members
 * Notify the Quest Engine of the L2Attackable death if necessary
 * Kill the L2NpcInstance (the corpse disappeared after 7 seconds)
 *
 * Caution: This method DOESN'T GIVE rewards to L2PetInstance
 *
 * @param killer The L2Character that has killed the L2Attackable
 */
@Override
public boolean doDie(L2Character killer)
{
	// Kill the L2NpcInstance (the corpse disappeared after 7 seconds)
	if (!super.doDie(killer))
		return false;

	// Notify the Quest Engine of the L2Attackable death if necessary
	try
	{
		L2PcInstance player = null;

		if (killer != null)
			player = killer.getActingPlayer();

		if (player != null)
		{
			if (getTemplate().getEventQuests(Quest.QuestEventType.ON_KILL) != null)
				for (Quest quest: getTemplate().getEventQuests(Quest.QuestEventType.ON_KILL))
					ThreadPoolManager.getInstance().scheduleEffect(new OnKillNotifyTask(this, quest, player, killer instanceof L2Summon), _onKillDelay);
		}
	}
	catch (Exception e) { _log.log(Level.SEVERE, "", e); }
	return true;
}

 

And in enterworld.java, find the good place to put (around the end, as enterWorld initializes many things) - I perhaps made errors, I just edited with notepad and didn't check synthax/logic :

 

if (Config.ENABLE_ANTIBOT_SYSTEM)
{
private static int AntiBotKills = 0;
private static int Change = 0;
int AntiBotKillsCheck = (Config.ANTIBOT_KILLS_CHECK);
NpcHtmlMessage npcHtmlMessage = new NpcHtmlMessage(0);

Change = Rnd.get(8);
AntiBotKills++;

if (AntiBotKills >= AntiBotKillsCheck)
{
	killer.setIsParalyzed(true);
	AntiBotKills = 0;
	switch(Change)
	{
		case 0:

If you have ever botted before with programs like L2Net you know that when your bot loggs in you can just sit there for a few minutes and watch it for the capatcha to load up.

 

What you could do on enterworld.java is add a random int for the loading of the capatcha and have the integer be a large number.

 

So player enters - the code assigns random time before load capatcha - when time runs out loads capatcha... not that hard to edit form your current code.

A generated number / suit of letters/number will show the asked code on the html ("To play enter following code : blablabla"), so it's exploitable as the answer is shown.

 

The only real way would be to call an image. The other solution is as the topic owner made, but once the guy got all possible questions/answers, it's bypassed.

I gave all codes and what you had to do, so now go work and come if you got issues compiling/ingame :P.
