|

body.hints:before,
|
* This code is designed to illustrate the non-intuitive approach to an
|
||||||
body.hints:after {
|
* implementation, building a snake game as a cellular automaton rather
|
||||||
display: block;
|
* than the more intuitive, a set of entities (OOP) or a number of sets
|
||||||
position: absolute;
|
* of procedures and data structures, directly emulating the "tactile"
|
||||||
left: 0;
|
* perception of the game, i.e. independent field, snakes, walls, apples
|
||||||
top: 12.5%;
|
* and their interactions.
|
||||||
bottom: 12.5%;
|
*
|
||||||
z-index: 100;
|
* 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
|
||||||
body.hints:before {
|
* step:
|
||||||
content: "";
|
* - empty cells, apples and walls just sit there
|
||||||
width: 100%;
|
* - "snake" cells:
|
||||||
border-top: dashed 0.5vmin red;
|
* - decrement age
|
||||||
border-bottom: dashed 0.5vmin red;
|
* - if age is 0 clear cell
|
||||||
}
|
* - if cell has direction (i.e. snake head)
|
||||||
body.hints:after {
|
* - if target cell is red (apple) increment age
|
||||||
content: "↺↻";
|
* - color new cell in direction:
|
||||||
width: 37vmin;
|
* - set age on to current age + 1
