Detailed Description

Interface of the classes that maintain sprites properties.

Date:

April 15, 2003

All sprites are almost the same, but to distinguish sprites that can handle an advanced interaction (entities) from those which do not (backgrounds), we are going to call Background Sprites to those objects that never move, and that have no other purpose in the game other than to look nice and occupy a space in the world (some times a solid space). Background sprites must use Mask maps if they need some sort of collision detection. An example of background sprites would be a flower, or a fence.

Entities, on the other hand, are sprites that can maintain an advanced interaction with other entities. This advanced interaction is ruled by the entity's script file. An enemy or a chest are classic examples of entities. Entities can have either of two methods for collision detection: the use a mask map (as background sprites) or the use any of the collision detection functions inside its associated script.

A mask map is a special type of sprite that it's attached to backgrounds or to some entities. Mask maps are not visible in the game, its functionality is more related to the behavior of other entities approaching to its parent background or entity. A mask map can be set to solidify objects or to make objects harder to penetrate. This is done using different colors, in the mask, to map different grades of body solidification, matching the areas of the background or entity sprite that need to be solidified. Using different shades of red, the closer it gets to the red, the easier it's to pass through. Solid red, howeve, only slows down any entity trying to cross the mask, while green presents no obstacule at all, as if no mask map existed in that zone)
