Topic Starter	Topic: passing strings from cgame to game
Xamis Recruit Joined: 14 Feb 2010 Posts: 4	Posted: 07-29-2011 08:29 AM                  getting frustrated trying to get this to work I have a cvar (vmCvar_t gear ) in the config file that I can read using gear.string, from inside cg_ files, no problem there, but I need to pass that string to game files, specifically g_weapon.c and g_client.c. I am really struggling to get this to work. I tried creating a variable in bg_ that I can use to hold the data, but when I print out the variable inside g_client.c it's value is NULL. I have had no problems passing other types of data this way, but passing a string of characters just isn't working for me. Any suggestions on how to accomplish this.

Grep the source for `CG_ConfigString` and `trap_SetConfigstring`, that'll show you how to pass data between them.

The opposite of what I need. I needed to pass info from a cvar on the client to the server. I figured out how to do it, and it was very easy and straight forward. Look into Info_ValueForKey( ). I passed the info in the clientinfo config string.

I printf what gets passed through Info_ValueForKey and that method is not being used to pass the data. How else could the data get sent from cgame to game?

The clue is the bit about clientinfo. That is client specific data that's transmitted to the server
