Orange Box code

Problem: You are unable to run maps after just having compiled a Half-Life 2: Multiplayer mod with the Orange Box code. No source code files have been changed.

Symptoms: Errors in the console such as:

DataTable warning: No matching RecvTable for SendTable 'DT_TeamTrainWatcher'.
Client missing DT class CTeamTrainWatcher
Host_EndGame: CL_ParseClassInfo_EndClasses: CreateDecoders failed.

Followed by the user being dropped from the server.

Cause: "Game_HL2MP-2005.sln" does not include the files for the TeamTrainWatcher entity on the client side. ----

Solution:

• In Visual Studio, right click on the Source Files Folder in the Client project
• Select add existing
• Select c_team_train_watcher.h and c_team_train_watcher.cpp
