Code Uber Cancellation.

[An4rchy]

Hey all. It's been long since i was active here..

So i wanted so share sth i created for a server that i was working on, it's the custom cancel that the buffs return after x time..

 

CustomCancelTask.java

package net.sf.l2j.gameserver.model.entity.custom;

import java.util.Vector;

import net.sf.l2j.gameserver.model.L2Skill;
import net.sf.l2j.gameserver.model.actor.instance.L2PcInstance;

/**

public class CustomCancelTask implements Runnable
{
private L2PcInstance _player = null;
private Vector<L2Skill> _buffs = null;

public CustomCancelTask(L2PcInstance _player, Vector<L2Skill> _buffs)
{
	this._player = _player;
	this._buffs = _buffs;
}

@Override
public void run()
{
	if (_player == null || !_player.isOnline())
	{
		return;
	}
	for (L2Skill s : _buffs)
	{
		if (s == null)
		{
			continue;
		}

		s.getEffects(_player, _player);
	}
}
}

 

And on gameserver/handlers/skillhandlers/Cancel.java

 

Add:

Vector<L2Skill> cancelledBuffs = new Vector<>();

 

Above these variables:

 

int lastCanceledSkillId = 0;

int count = skill.getMaxNegatedEffects();

 

And add:

					if (!cancelledBuffs.contains(effect.getSkill()))
					{
						cancelledBuffs.add(effect.getSkill());
					}

 

Under this maybe:

 

// Stores the last canceled skill for further use.

lastCanceledSkillId = effect.getSkill().getId();

 

And finally add at the end of the method:

		if (cancelledBuffs.size() > 0)
		{
			ThreadPoolManager.getInstance().scheduleGeneral(new CustomCancelTask((L2PcInstance)target, cancelledBuffs), 5*1000);
		}

 

(Where 5 here is the seconds you want to delay until give the buffs back.)

 

However i would like to mention a few stuff:

- It was lazy coded, to be honest, since it gives the buff with full buff time.

- It can be used as bug, due to the above.

- It is coded on aCis.

- Sorry for not patch file but i committed that and the svn was deleted.

 

:) :)

 

Update:

 

These 2 patches should fix the code to work as it should. It was Justice's request.

Btw, i have to say a big sorry for the blindness my old cancel code for l2elcardia caused to Elfocrash and Pauler  :alone:

[xdem]

nice share, and nice code dude, nice to see vectors on l2 =D, gj keep up

Hehe ;) As always, can't really quit l2j or this forum generally ;p Even if lol took over my pc for several months :D

 

Thanks mate :)

 

this wasnt shared by rizzla?

Well sorry if that's the case, but i was inactive for several months, as i mentioned above.. It should be locked if it exists then..

[Devlin]

Well, it's nice (I hope, you remember :D).

 

Good job, and glad to see you back!

[KderD64]

this wasnt shared by rizzla?

 

Yes, this custom cancellation was already shared as I remember, but I might be wrong.

[Devlin]

Yes, this custom cancellation was already shared as I remember, but I might be wrong.

Check both codes, and you will understand.

[Stewie]

The code is diff from the one that is already shared... as i see

Someone test and reply, i'm waiting...

Romeo one was with bugs, i hope this one is bugless and will restore all buffs + self buffs..

[KderD64]

This cancellation as I recall is exploitable in dueling system and olympiad games, you might want to check it out.

with some edits it can be perfect... i accept that any developer can do the restrictions since they are easy

Indeed, that's why I was telling not to take only the raw code and apply it, it needs some adapting also.
