Help L2j Architecture

[Sinistroyer]

Hi 

 

I'm googling right now to get info about how l2j works.

My goal is to learn how to fix  but I don't know how to approach or how much I have to go deep.

I know a bit of java and I keep studying it.

so What Does fix mean ? 

Do I need to know java and what else ?

I would like learn to create events , fix features , change position of mobs bugged etc

 

Thanks for any help

first you need to go to this link, then choose random source and run in your local server to know better about server structure (for this you need  to know java), then learn how to datapack connected with server (about parsing and db)

Hi , 

I have a local server ready with L2jMobius.

I just realized that db tables are different from the old l2j server ( the original I think it is).

For example I have to set my char  with admin access level  and I've found the  files with this text inside :

# This option will set the default AccessLevel for MasterAccess
# Pls be carefully with that. Chars with this AccessLevel have
# right to execute every AdminCommand ingame.
# Default = 100 - Max. 255
MasterAccessLevel = 127

# This option will set the default AccessLevel for UserAccess
# Chars with this AccessLevel have user rights
# Default = 0 - Max. 255
UserAccessLevel = 0

on L2jmodbius is named "Access.ini"

  but the  "admin_command_access_rights" table doesn't exist in my DB 

 

 

maybe a standard doc doesnt exist and I have to ask to L2jmodbius forum

or i have to learn by reading Java code ?

For example I would like understand where the npc are "built" in DB , how do they work ?

How Do the db handle the item ?( it uses numbers..) ectc

I mean the architecture that is how every stuff is linked 

 

Thanks fro any help

The only difference is some static data tables like npc and droplist are now compined into .xml in the stats folder in the datapack.

None will give you the use of the 1500+ core files of a L2J project.

 

I invite you to be curious and explore it. L2J is 80% project knowledge and 20% Java.

 

Langages to know : HTM, XML, SQL, Java. Some projects still have scripts under Jython.

 

With ok logic and no specific knowledge, you can expect to be "mhe" after 6 months of tries/fails, "ok" with 1y and "decent" after 1y+.

 

stackoverflow website is the best way to get answers regarding Java structures/logic/patterns in general.
