Anti-KS System

Statique · March 20, 2010

It is very annoying usually in server with farming zones and mobs which they won't die easily when the player is about to kill it someone else comes up makes the last hit and takes the reward. Can somehow make a way to give the reward to the player which has the player on him which means if I keep hitting a mob it faces me and hits me if somebody else comes and starts hitting if his damage is more that mine he will take the mob toward him and the mob will start hitting him instead of me, what I want to do that the reward from the mob should take the person who has the mob on him which means that the reward should go to the player who has the mob on him and hits him.

confusing...

thanks in advance...

one way is to make a instance ...

what i mean? one new instance .. example L2AntiKsMonsterInstance...

and spawn custom mobs .. if we talk for pvp serv... for low is not this way...

code smthink like this ..

On first hit mob get name of attacker

on die. if last hit by first<name> reward else nothing ...

i like this idea .. maby in monday i try to do it ... im work full today and tomorow ... i no have time

varens · March 20, 2010

i have better idea, but sey my what chronicle and what team files you use:)

you need w8 becouse my internet is so sh it and i need download that file souroce;p

Sindelia · March 20, 2010

Just an opinion Static13. KS is part of L2 and generally of all games. The logic is that the player that has aggro of the mob gets the loot. It's part of the game :p

Statique · March 20, 2010

It's really disturbing when you are about to kill a mob and somebody else comes up makes the last hit and takes the reward ya know...

Sindelia · March 20, 2010

Of course I do know that ^^ . I've thought of adding a protection from KS in my farming zone too but I think it won't be such a problem but, if varens codes it it would be great ;)

Statique · March 20, 2010

Well think it like this; If your farming zone contains mobs which they can easily get killed it is not a problem I wouldn't add it too, but if the mobs are pretty strong and takes maybe 3-4 minutes to get killed it is really annoying believe me on this ;)

Sindelia · March 20, 2010

My mobs do take a few mins to kill. So...I'll be waiting for varen's code ;)

Varens, your try is good but, it would be better to make a new instance. Or, in your code define certain NPCs that should behave like that.

varens · March 20, 2010

for what make new instance?

here you have config for protect moobs by ID:

So with this code if it will work the reward for the mob-kill will go to the person who has the aggro, right?

I'll try it when I'll get home...

varens · March 20, 2010

no, who make biggest dmg on moob get the drop

Sindelia · March 20, 2010

I'll test it and provide feedback.
