"I made the assignment to a global variable" cvar is NULL when the dll loads.
-----Original Message----- From: hlcoders-boun...@list.valvesoftware.com [mailto:hlcoders-boun...@list.valvesoftware.com] On Behalf Of Klaus Müller Sent: Wednesday, May 19, 2010 10:43 AM To: Discussion of Half-Life Programming Subject: Re: [hlcoders] ConVar assignment breaks game Okay, seems like it broke the game because I made the assignment to a global variable, although I still don't understand what the problem with that is. So if I assign it to a member variable of my panel resp. my property sheet class, at least the game remains functional. The problem still remains though that I can't change the value of the variable.
