Game Structure, Mapping Structure, Item Structure, and alot.

[LookingForAPath]

Okay, so for mapping, I plan on creating my own mapper(somewhat as models will be made in a modeling program and put in the map with the mapper).

The reason for this is, I want to make a 3D Rpg as my first project. Although this may take tons of time, I do have alot of time to spare.

So for mapping, I was wondering, how do you set up your system?

I plan to have a class for the Terrains(huge terrain models) and LOD on each one of them, a class for each door in the world, and a class for "world" items and a struct for NPCs. Using this method, I could save and load based off this structure.

And for actual "game" saves I plan to "oad the original map with all NPCs,
items, and etc in their original places, first. Then load the "saved" games variables. Which saved game variables would only include which ones have been killed and where their bodies currently are, what quest have been done, and etc.

On the other hand, I want some constructive criticism on better ways to do this, or how this might fail big time.

Thanks for all comments and criticism,
Zac
