Tiled Geometry

Utilities for 2-D tiled geometry

This library contains several useful functions and classes for dealing with 2-D tiled geometry.

Installation

npm install tiled-geometry

API

Constants and utlities for 2-D tiled coordinate spaces:

• Direction - constants for eight compass directions
• Turn - constants for rotation among eight compass directions
• CardinalDirection - constants for four cardinal directions
• CardinalTurn - constants for rotation among four cardinal directions
• CardinalDirectionFlags - bitmask constants for four cardinal directions
• Flip - constants for mirroring the coordinate space
• CardinalOrientation - constants combining CardinalDirection and Flip
• Axis - constants for the two major axes

Classes for coordinates, shapes, masks, and more:

• Offset - a location or relative offset
• Size - a two-dimensional extent
• Rectangle - a rectangle (with offset and size)
• Mask - a rectangular area with boolean values for each cell
• MaskRectangle - a mask with an offset
• RasterMask - a mask encoded as "raster lines"
• CardinalPath - a path on the grid, moving only in the four cardinal directions
• TransformRectangle - maps a rectangular area onto a grid with transformations
