Function: nearestOpen()

function nearestOpen(
   g, 
   tx, 
   ty, 
   maxRadius?, 
   ok?
): TilePoint | null;

Defined in: src/nav/nearestOpen.ts:8

The open tile nearest to (tx, ty) within maxRadius rings, or null: a start or a goal inside a rock still gets a route. ok narrows what counts (an open tile that is not a door, say). On each ring the closest tile wins, not the first scanned — scanning order once always picked the ring's top-left corner.

Parameters

Parameter	Type	Default value
g	NavGrid	undefined
tx	number	undefined
ty	number	undefined
maxRadius	number	12
ok	(x, y) => boolean	...

Returns

TilePoint | null
