I just use tmap to save and load map game data at runtime.
FStruct save the data of map, may be a big size.
there are 2 way to use tmap
normal type (Will the Add() function clone the struct?)
TMap<FIntVector, FStruct>
pointer type
TMap<FIntVector, FStruct*>
which is efficient?
I like to use map<xx, class*> with STL.
