check L2Npc.java line 1526. whats there?

[Michalis]

is this

//If killer instanceof L2PetInstance or instanceof L2SummonInstance, this is going to get the player that controls the killer.
L2PcInstance player = null;
player = killer.getActingPlayer(); <--------- this is the line 1526

[pavel2451]

Try this

Code: Select all

        // Kill the L2NpcInstance (the corpse disappeared after 7 seconds)        if ( killer == null || !super.doDie(killer))            return false;
