Code Easy Boss Engine

[An4rchy]

Hey there.

 

This is a boss engine i created long ago, cause i always found every boss/grand boss engine difficult/weird to use. It's really easy to use. The code may be weird because i remember to be experimenting on stuff when creating this. Also, i know it could have been done in a better way(with saving each boss data and other stuff). Coded on aCis, can't remember revision.

 

There are also some boss examples i used.

In L2MonsterInstance under doDie() method, add this check:

 

        if (isCustomBoss())
        {
            CustomBossManager.getInstance().getCustomBoss(getNpcId()).delete();
        }

 

and this method:

 

    public boolean isCustomBoss()
    {
        return CustomBossManager.getInstance().getCustomBoss(getNpcId()) != null;
    }

 

Also register the CustomBossManager in Gameserver.java.

 

How to use it:

Simple, create a normal monster with super stats and super drops, make a new class that extends CustomBoss, add it's data there, register it to CustomBossManager and you're done. The bosses must be type L2Monster in order to work properly.

 

About this ForestGod i won't share the npc data just make new ones.

Actually i'm playing a lot of LoL these days, but i like to remember the old times occasionally :)

You can explain a little bit more

 make a new class that extends CustomBoss, add it's data there, register it to CustomBossManager and you're done
