continuous-observer
Take a continuous ndarray and, given a set of "observable" positions, automatically add and remove chunks as required.
Use this for painless chunk management with one or more visible perspectives.
Installation
npm install continuous-observer
Usage
observe = require('continuous-observer')(field[, range[, linger]])
Returns a function that can be used to update the chunks in use, given a
continuous ndarray (field
). Optionally:
range
is the amount of surrounding chunks to include. Defaults to 1.linger
is the amount of surrounding chunks to not remove when cleaning up. Defaults torange
, and cannot be set to belowrange
.
observe(points)
points
is an array of arrays, with each array representing an observer's
position. Can also handle a single array as well, if you're only using one
observer.
// Create a continuous ndarray with 32x32 chunksvar field = shape: 32 32// Create the observervar moveTo = field 1 2// "Move" the observer to the origin// Ahead one chunk// Ahead another chunk - this will remove// some of the older chunks.// Including another observer just involves// adding another position to the array.
