Reference · Mazes, arrows and mixed boards
cellsAlongfunction
The cells a pointer enters moving from one shown point to the next: the straight path between them cut into steps of a third of a cell and each step carried back into the maze. Every cell it passes is offered in order, so a fast finger skips none. The board and the tests use this one function, so a line drawn on a turned board is exactly the line drawn on one that is not.
Import it
import { cellsAlong } from "@johnmorrisdotca/meikyuu";Definition
function cellsAlong(grid: Grid, turn: Turn, from: Point, to: Point): number[]Parameters
| Name | Type | Description |
|---|---|---|
grid | Grid | The valid native flat or surface cell graph. |
turn | Turn | The native quarter-turn setting. |
from | Point | The start cell or pointer point specified by the signature. |
to | Point | The destination pointer point specified by the signature. |
Returns
