I placed this script in my "lua > autorun > client" and it worked but when I placed it on my server's "lua > autorun > client" it didn't work! Where should I place it so everyone in the server gets the effect?

[.\\Shadow}]

lua/autorun/

At the top of the file, add:

[lua]if SERVER then
AddCSLuaFile( "filename.lua" )
return
end[/lua]

Is that "filename.lua" suspose to be the script file name?

EDIT: Nevermind, Google was my friend. Thanks for the reply!
