I like that idea. Do you have any good resources for bison? I've tried a few times and never managed to understand how it works all that well.

In general, for complex databases, I prefer to write custom reader/writers using bison/flex. An ASCII file that mirrors your classes well has many advantages. You can edit it easily, and it's fairly simple to maintain backwards compatibility with previous versions. BillOn Sun, Jul 12, 2009 at 12:39 PM, Tyler Littlefield<tyler@xxxxxxxxxxxxx> wrote:
hmm, so I would store the pointer to an int/string/double.

Just don't make it a map of primative to primative, make it a map of primative to object. That object can be of any type you like.

Each player will have a set of keys that will be stored, name, connect time, creation time, etc. I was thinking of storing these in a map, but that requires that the map hold multiple values; something which the c++ map doesn't do. So, I'm trying to figure something out. I'd like to be able to store player data, and a list of the player's inventory so the objects can be recreated when the player connects somehow. I would need to store object type, name, etc etc. I'm not quite sure how I could achieve this easily; I could possibly itterate through the map once I've gotten the data type thing figured out and do something like write key=value. Then when I loaded it I could just strtok on the = and set that up, but I'm not quite sure how I'd handle inventory and that. This is the only snag I'm having so far, and I'm not able to move on without it, as I'm to the point where I need to start saving player data, so help would be really appriciated at this point. :) Thanks, __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind__________ View the list's information and change your settings at //www.freelists.org/list/programmingblind
