Modes

VFS.RAW
VFS.MOD (unimplemented, acts like VFS.ZIP)
VFS.MAP (unimplemented, acts like VFS.ZIP)
VFS.BASE (unimplemented, acts like VFS.ZIP)
VFS.ZIP
VFS.RAW_FIRST
VFS.ZIP_FIRST
VFS.RAW_ONLY (same as VFS.RAW)
VFS.ZIP_ONLY (same as VFS.ZIP)

Files

VFS.Include (if enviroment=nil then use current one)

 ( string "filename" [, table enviroment = nil [, number mode ] ] ) ->

VFS.LoadFile

 ( string "filename" [, number mode ] ) -> nil | lstring data

VFS.FileExists

 ( string "filename" [, number mode ] ) -> boolean

VFS.DirList

 ( string "directory" [, string "pattern" = "*"  [, number mode ] ] )
   -> { [1] = string filename, ... }

VFS.SubDirs

 ( string "directory", [, string "pattern" = "*"  [, number mode ] ] )
   -> { [1] = string subdir1, ... }

VFS.UseArchive unsynced only!

 ( string "filename" [, number mode ], lua_function [, arg1 [,arg2 ]] )
   -> result1,result2,... of the given lua_function

VFS.MapArchive unsynced only!

 ( string "filename/modname of archive", [string checksum of archive] )
   -> bool

Permanently loads an archive into the VFS (to load zipped music collections etc.). If checksum is given it checks if the to be loaded file is correct, if not then it won't load it and return false.

Packing

The Pack- and Unpack-functions are used to convert numbers->strings and strings->numbers. So you can read a binary file and then convert the received strings back to numbers and the other way around. Also you can use it in combination with the SendLuaXYZMsg-functions.

VFS.PackU8

VFS.PackU16

VFS.PackU32

VFS.PackS8

VFS.PackS16

VFS.PackS32

VFS.PackF32

arguments are:

VFS.PackX( number arg1, number arg2, number arg3, ... ) -> string

VFS.PackX( {[1]=number,[2]=number,..} ) -> string

VFS.UnpackU16

VFS.UnpackU32

VFS.UnpackS8

VFS.UnpackS16

VFS.UnpackS32
