*
|
||||
* Simple Snake
|
||||
*
|
||||
* This code is designed to illustrate the non-intuitive approach to an
|
||||
* implementation, building a snake game as a cellular automaton rather
|
||||
* than the more intuitive, a set of entities (OOP) or a number of sets
|
||||
* of procedures and data structures, directly emulating the "tactile"
|
||||
* perception of the game, i.e. independent field, snakes, walls, apples
|
||||
* and their interactions.
|
||||
*
|
||||
* In this approach there are no entities, no snakes, no apples, no
|
||||
* walls, just a set of cells in a field and cell behaviours per game
|
||||
* step:
|
||||
* - empty cells, apples and walls just sit there
|
||||
* - "snake" cells:
|
||||
* - decrement age
|
||||
* - if age is 0 clear cell
|
||||
* - if cell has direction (i.e. snake head)
|
||||
* - if target cell is red (apple) increment age
|
||||
* - color new cell in direction:
|
||||
* - set age on to current age + 1
|
||||
* - set direction to current
|
||||
* - clear direction
|
||||
*
|
||||
* NOTE: that in the above description some details are omitted for
|
||||
* clarity...
