Function: hasLineOfSight()
hasLineOfSight(
grid,a,b):boolean
Defined in: packages/wayfinding/src/string-pull.ts:14
Raster hit-check: true when every cell the straight line between a and b passes through (via the same supercover walk used to stroke walls) is walkable.
This is the technique named grid_line_raster_hit_check in the Wayfinding v2 plan's HEB crib sheet (§7) — an independent implementation written from that description, not ported code.
Parameters
grid
a
b
Returns
boolean
