lineRunsfunction
A line as the runs it is drawn in, each a list of points through its cells' middles. On a board that wraps, a step across the join ends one run a cell out beyond the edge (in the ghost) and starts the next a cell out beyond the other edge, so the line is seen to leave and come back. Through a portal the line is two runs: it ends just inside the ring it went into, and the next starts just inside the ring it comes out of, going on the same way.
Import it
import { lineRuns } from "@johnmorrisdotca/tsunagi/draw";Definition
function lineRuns(layout: LinkLayout, geometry: TsunagiGeometry, line: readonly number[]): TsunagiPoint[][]Parameters
| Name | Type | Description |
|---|---|---|
layout | LinkLayout | The decoded native board and its rule settings. |
geometry | TsunagiGeometry | The board-to-pixel geometry. |
line | readonly number[] | The cell sequence of one native line. |
Returns
