Make sure you have a LINK_ENTITY_TO_CLASS that links the entity properly on both the server and client, as well.
server LINK_ENTITY_TO_CLASS( derivedentity, CDerivedClass ); Client LINK_ENTITY_TO_CLASS( derivedentity, C_DerivedClass ); -Tony -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Skyler Clark Sent: February-11-09 2:20 AM To: Discussion of Half-Life Programming Subject: Re: [hlcoders] CNetworkVar madness This is probably an obvious question, but it's always best to make sure obvious ones were considered... Are you sure the derived class is actually the one being instantiated (on both client and server)? -Skyler On Wed, Feb 11, 2009 at 12:58 AM, Josh Clark <[email protected]> wrote: > Hi, all.
