Function: forEachLink()

forEachLink(layers, node, diagonals, visit): void

Defined in: packages/world/src/nav-layers.ts:194

Calls visit with every node linked to node in the four (or, with diagonals, eight) neighbouring cells, and the step's length in cells (1, or √2 across a corner), always in the same order. A diagonal step is taken only where it can be walked round both ways: a node of each cell it cuts between is linked to node and to the node it reaches, so no wall's corner nor a floor's edge is cut.

Parameters
