vec2-recycle

Another vanilla vector 2 library with recycling

Similar in scope (and based on) https://github.com/tmpvar/vec2.js. Differences:

  • uses a cache to recycle vectors to minimize garbage collection
  • uses a number[2] without any prototypes
  • is not watchable (unlike the above library--removed for speed purposes)

Simple Example

import * as vec2 from 'vec2-recycle'

const v1 = vec2.create(5, 4)
const v2 = vec2.create(8, 9)

// copies to a new vector
const v3 = vec2.add(v1, v2, true)

// v1 is replaced
vec2.subtract(v1, v2)

vec2.recycle(v2)
