//main class

public class Devs {

 

public static void main (String[]args) {

 

Tryskel dTryskel=new Tryskel ();

Wyatt dWayatt=new Wyatt():

 

}

}

 

//1st class

public class Tryskel {

 

public boolean L2jdeveloper=true;

public boolean Professional=true;

public boolean Clever=true;

public boolean Kind=true;

public boolean Cool=true;

 

}

//2nd class

 

public class Wyatt {

 

public boolean L2jdeveloper=true;

public boolean Professional=true;

public boolean Creative=true;

public boolean Strict=true;

public boolean Tall=false; //making joke

 

 

 

 

 

 

 

}

 

//3rd class

 

public class Me extends Wyatt {

 

 

 

// SO everything i wrote here and declaration of Wyatt will be applied to me ?

 

//am i right?

 

 

 

 

 

}

You can reuse any boolean of Wyatt in Me. Adding your own variables in Me are only shared amongst classes extending Me, or Me itself.

 

On a L2J base :

 

L2PcInstance extends L2Playable which extends itself L2Character. Meaning a L2PcInstance can reuse stuff from L2Character.

L2PetInstance extends L2Summon which extends L2Playable which extends L2Character.

 

As you can see the relation between players and summons stop at L2Playable, meaning whatever you edit at and before L2Playable can affect both.

 

On another note, you can override methods content with @override. Overriden methods means you "re-write" content of the method to fit with your class.

 

To take an example, isAutoAttackable() is overriden following cases : returning always true for L2Character, but not always true for summons and players.

 

So if you don't rewrite anything it will fully inherit, but you can give exceptions to that previous statement using override.

 

Hope it's clear. If it's not, consider to use a paper and a pencil and draw a tree. I give you the beginning :

 

 

L2Pet    L2Servitor

   |         |

L2Summon           L2PcInstance

     |                             |

     ------  L2Playable ---------

                    |

                   ...

    • I'm using Myext64 HF and recently tried to replicate the "br_xmas09_event" Raising Rudolph Event. Detailed event information can be found at https://legacy-lineage2.com/news/_rudolf_the_red.html After configuring .eventdata.xml and starting the server, t  server log shows: 12/02/2025 15:39:01.809, [NO_ERROR] SpawnEx2 [br_xmas2009_invisible][schuttgart20_npc2213_xs03m1] [1][0][0][0][0][346796390] 12/02/2025 15:39:02.057, DummyPacket received from L2Server 12/02/2025 15:39:02.058, server socket close 312ac(f0820224) error(997) 12/02/2025 15:39:02.058, [CallStack][tid:0][tick:2][0] Begin 12/02/2025 15:39:02.058, [CallStack][tid:0][tick:2][1][0] void __cdecl IOThreadCallback::IOThread_common(void) 12/02/2025 15:39:02.059, [CallStack][tid:0][tick:2][2][1] void IOThread_common 1 12/02/2025 15:39:02.059, [CallStack][tid:0][tick:2][3][2] void __cdecl CIOSocketEx<class CIOBufferEx<16384> >::Close(void) 12/02/2025 15:39:02.059, [CallStack][tid:0][tick:2][4][3] void __cdecl CServerSocket::OnClose(void) 12/02/2025 15:39:02.059, [CallStack][tid:0][tick:2][5] End l2server log: 12/02/2025 15:39:02.112, npc server closed(127.0.0.1) error: 64 read buffer size: (server:0 npc:0) 12/02/2025 15:39:02.112, [NO_ERROR] L2Server is under protection mode!!! 12/02/2025 15:39:02.112, [NO_ERROR] L2Server is under protection mode!!! 12/02/2025 15:39:02.112, [NO_ERROR] L2Server is under protection mode!!! 12/02/2025 15:39:02.131, dwTime[0] < 80 !!!!!!! 12/02/2025 15:39:02.131, [CallStack][tid:7][tick:1][0] Begin 12/02/2025 15:39:02.132, [CallStack][tid:7][tick:1][1][0] void __cdecl IOThreadCallback::IOThread_common(void) 12/02/2025 15:39:02.132, [CallStack][tid:7][tick:1][2][1] void IOThread_common 1 12/02/2025 15:39:02.132, [CallStack][tid:7][tick:1][4][3] void __cdecl NpcSocket::OnClose(void) 12/02/2025 15:39:02.132, [CallStack][tid:7][tick:1][3][2] void __cdecl CIOSocketEx<class CIOBufferEx<16384> >::Close(void) 12/02/2025 15:39:02.132, [CallStack][tid:7][tick:1][5] End 12/02/2025 15:39:31.767, server closed(127.0.0.1) Error: 64 Read buffer size: (server:0 npc:0) 12/02/2025 15:39:31.768, [NO_ERROR] Logout All Characters : 1   The NPC server sent a packet to the L2 server while generating the br_xmas2009_invisible game NPC server, and the NPC server subsequently crashed.     After some digging, I found a clue in a very old MXC post, but the fix was for the GF version. The whole problem is in l2server side support for NPC function CreateOnePrivateNearUser. It sends CreatePacket but Koreans made some changes in it (added instance ID) so it got broken. As Santa event is the only AI that uses this function, they probably don't know about it    So is there a way to fix this problem, specifically for Myext64 HF? I'd be happy to buy him coffee. set_compiler_opt base_event_type(@NTYPE_NPC_EVENT) class ai_br_vital_manager : default_npc { parameter: int br_vitality2010_EVENT_ID = 20108888; handler: EventHandler CREATED() { } EventHandler TALKED(talker) { ShowPage(talker, "br_vi_stevu001.htm"); super; } EventHandler GIVE_EVENT_DATA(talker, i0, i1, i2, i3, i4) { i3 = i2 / 3600; i2 = i2 - i3 * 3600; i4 = i2 / 60; i2 = i2 - i4 * 60; if (i1 == 20108888) { if (i0 == 1) { CastBuffForQuestReward(talker, @s_br_vitality_day_1); CastBuffForQuestReward(talker, @s_br_vitality_day_2); ShowPage(talker, "br_vi_stevu002.htm"); } else { ShowPage(talker, "br_vi_stevu003.htm"); } } } EventHandler MENU_SELECTED(talker, ask, reply, c0) { if (ask == 50021) { select (reply) { case 1: CanGiveEventData(talker, 20108888); break; case 2: if (talker.level <= 75) { ShowPage(talker, "br_vi_stevu005.htm"); } else if (IsInCategory(@fighter_group, talker.occupation)) { CastBuffForQuestReward(talker, @s_wind_walk_for_newbie); CastBuffForQuestReward(talker, @s_shield_for_newbie); CastBuffForQuestReward(talker, @s_magic_barrier_for_adventurer); CastBuffForQuestReward(talker, @s_bless_the_body_for_newbie); CastBuffForQuestReward(talker, @s_vampiric_rage_for_newbie); CastBuffForQuestReward(talker, @s_regeneration_for_newbie); CastBuffForQuestReward(talker, @s_haste_for_adventurer); ShowPage(talker, "br_vi_stevu006.htm"); } else if (IsInCategory(@mage_group, talker.occupation)) { CastBuffForQuestReward(talker, @s_wind_walk_for_newbie); CastBuffForQuestReward(talker, @s_shield_for_newbie); CastBuffForQuestReward(talker, @s_magic_barrier_for_adventurer); CastBuffForQuestReward(talker, @s_bless_the_soul_for_newbie); CastBuffForQuestReward(talker, @s_acumen_for_newbie); CastBuffForQuestReward(talker, @s_concentration_for_newbie); CastBuffForQuestReward(talker, @s_empower_for_newbie); ShowPage(talker, "br_vi_stevu007.htm"); } break; case 3: c0 = GetSummon(talker); if (talker.level <= 75) { ShowPage(talker, "br_vi_stevu011.htm"); } else if (IsNullCreature(c0) == 0 && IsInCategory(@summon_npc_group, c0.class_id) && IsInCategory(@pet_group, c0.class_id) == 0) { CastBuffForQuestReward(c0, @s_wind_walk_for_newbie); CastBuffForQuestReward(c0, @s_shield_for_newbie); CastBuffForQuestReward(c0, @s_magic_barrier_for_adventurer); CastBuffForQuestReward(c0, @s_bless_the_body_for_newbie); CastBuffForQuestReward(c0, @s_vampiric_rage_for_newbie); CastBuffForQuestReward(c0, @s_regeneration_for_newbie); CastBuffForQuestReward(c0, @s_bless_the_soul_for_newbie); CastBuffForQuestReward(c0, @s_acumen_for_newbie); CastBuffForQuestReward(c0, @s_concentration_for_newbie); CastBuffForQuestReward(c0, @s_empower_for_newbie); CastBuffForQuestReward(c0, @s_haste_for_adventurer); ShowPage(talker, "br_vi_stevu009.htm"); } else { ShowPage(talker, "br_vi_stevu010.htm"); } break; } } } } Another one is about the " br_vitality2010_event event".   GIVE_EVENT_DATA is likely the only one in the activity AI script that uses this handle.      
    • Offtopic, personal attacks, probably too old to use that much memes and what's YOUR actual contribution to L2J, in order I laugh aswell ?   The main poster quotes my pack so I answer accordingly, while you advertise L2JFrozen in both of your posts - discontinued since 2014 (? 1132 rev), with none taking back the open source lead while anyone could.   If you're somewhat affiliated to hopzone, you probably packed way more money than me. Packs don't make any type of money (barely 100e/month) and if you would follow me, you would know there are ways to handle it or even getting paid.   Hope I was short enough, 🧂🤡.
