Hey all.
I've written up a VergeC library that implements a tree structure. It should be easy to drop into your game if you want to use it. You can check it out here:
Click here for a sample of the tree library in action (run it and then look at v3.log)
Click here to take a look at data_trees.vc
The file has a passable explanation of how to use the library. If anyone really wants to use this and is confused by how it works, just let me know. Similarly, if you have no idea what a tree structure is, and there is enough of you who care to know, I can write up a simple explanation. I figure that I won't bother unless there's interest though.
