Hi, I'm working on Unity game for Windows Phone 8.1. The game is made with Unity Script. The problem is when I try to build the visual studio project I get this error message : Could not load file or assembAssets/Common/Scripts/BlackFader.js(58,9): BCE0005: Unknown identifier: 'iTween'. There also another 100 error messages for every row where iTween is used. The iTween's C# file is in the Plugins directory and I think it should be compiled on first pass. Is there something else that should be done to build the game ? Thanks in advance!
