this is a step for modding the game.
1. requirements:
- a lua ide, i prefer zeus ide (http://www.zeusedit.com/download.html)
- quickbms for extracting pak (http://aluigi.altervista.org/quickbms.htm) + bms script for the game (http://aluigi.org/bms/life_is_feudal.bms)
2. extract the pak file:
-extract quickbms in game folder, after put /life_is_feudal.bms in quickbms folder (you can put the quickbms folder where you want,i put in the game folder to facilitate me)
- open quickbms.exe (you find it in quickbms folder)
- select the life_is_feudal.bms file.
- select pack file you want to open
- select folder you want to extract (for facilitate me i create "extract" folder)
3. script and change the extracted file with lua ide (zeus ide) or program required from the file type.
4. delete all file you doesn't have modified in extract folder
5. put your folder in root folder of game
example:
- extracted gui.pak in extracted folder
- modified GameLook.png in gamefolder\extracted\gui\imagesets
- mv modified gui folder from gamefolder\extracted\ to gamefolder\
sorry for my english but i don't speak and write it very well, but i think you can understand how to do it.
