Examples of _api.alienfactory.javamappy.Block

_api.alienfactory.javamappy.Block
A simple bean class which represents a Block as used by Mappy.

A Block may contain up to 4 layers of images (1 background layer and 3 foreground layers), 7 fields of User data, quadratic collision information and 4 other flags.
