@class Grid
|
|
Grid is a logical segment of the game world represented inside TrinIty.
|
|
Grid is bind at compile time to a particular type of object which
|
|
we call it the object of interested. There are many types of loader,
|
|
specially, dynamic loader, static loader, or on-demand loader. There's
|
|
a subtle difference between dynamic loader and on-demand loader but
|
|
this is implementation specific to the loader class. From the
|
|
Grid's perspective, the loader meets its API requirement is suffice.
