[Guide]How to use the official launcher

[someone]

I know there are many Launchers released there. This guide is the same as the guides from Episode 2 section Guides.

 

Requirements:

- A WebServer(Apache you have it in Xampp package, IIS, nginx, lighttpd, Sun Java System Web Server)

- IP tool.

 

Setting Up:

If you want to create files do this before:WinXP:

Windows Explorer->Tools->Folder Options->View->(UnCheck)Hide Extensions for known file types

Win7:

Windows Explorer->Organize->Folder Options->View->(UnCheck)Hide Extensions for known file types

 

Or create the files with notepad:

Open Notepad->Write What you have to write in->File->Save as->(Write the name of the File in quotes)

 

Go to your htdocs or www(depending on what your WebServer is set). Create a folder called Launcher, inside the launcher folder create 3 files, and a folder:

notice.htm
update.htm
ip.txt
patches

With the IP Tool, edit the lccnt.dta file to the launcher folder:

lccnt.dta

http://localhost/launcher/

The format of the ip.txt:

1
http://localhost/launcher/patches/

If you have a public domain or a IP, instead of localhost you will put your public domain or IP. The ip.txt points to the folder where the file version.txt is.

 

For notice.htm and update.htm, this guide will help(takes half a day to learn it):

Updating the Client:

In the folder patches, create a file called version.txt, Write the client version in there.

version.txt:

1279

To add patches:

Create a Zip file with the name of the version, For example if you have 1285 into version.txt, and 1279 in the vtm.brn, the value in the vtm.brn will increment by 1, each time it downloads a patch, till it reaches the value in the version.txt(first will look for 1280.zip, then 1281.zip, 1282.zip, 1283.zip, 1284.zip,and lastly 1285.zip)

 

The Directory Structure in the ZIP file:

For example if you want to modify skills in your client, which is located in LC/Data/skills_usa.lod, In the zip file the will look Data/skills_usa.lod.

Example:

1580.zip

Data/skills_usa.lod
Data/World/StartZone/StartZone.wld
Bin/Engine.dll
sl.dta
