Except he said that "cvar->FindVar("r_decals")->GetString()" is working.
Perhaps you're changing the value too early and then what you have in
config.cfg overrides it? After setting it, check that it has been set by
printing the value and then maybe place a data breakpoint to see when the
value changes again.-----Original Message----- From: hlcoders-boun...@list.valvesoftware.com [mailto:hlcoders-boun...@list.valvesoftware.com] On Behalf Of Spencer 'voogru' MacDonald Sent: Wednesday, May 19, 2010 9:16 AM To: 'Discussion of Half-Life Programming' Subject: Re: [hlcoders] ConVar assignment breaks game "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.
