Status being a nubmer (ie 400), and response being the data.

zeros( n )
Returns an array of zeros of lenth n

sequence( n )
Returns an array of numbers from 0 .. n-1

randInt( n )
Returns a random int from 0 .. n-1

clearEmptyElements( array )
Remove all zero and falsy values from an array

randomizeArray( array )
Returns array with random-ordered elements using the Fisher-Yates-Knuth shuffle.

leftPad( str, len, fillerChar )

toRadians( x )
Convert x degrees to radians

toDegrees( x )
Convert x radians to degrees

hasDuplicates( n ) Returns true if array contains duplicates

choose( n, k ) The mathematical choose function. One-indexed

ithIteration( n, k, i ) Alias for ithCombination( n, k, i )

inverseIthIteration( n, combinationArray ) Alias for inverseIthCombination( n, combinationArray )

ithCombination( n, k, i ) Given a set of n items, k choices, and an index i, give me a k-sized array of the ith combination. 0 <= i < n.

inverseIthCombination( n, combinationArray ) Given a number n and combinationArray, convert the array into an ith ordering. k is infered from combinationArrays length.

Classes

new WET.game( THREE, gameTitle )
Given a three.js library let THREE = require( 'three' ), initialize a basic game environment using threejs. ie in index.js

WET = require( 'wetbox' )
THREE = require( 'three' )
game = new WET.Game( THREE, 'Wizzy boi' )

Window lickers listeners

keyListen( isEnable, up, left, down, right, crouch, space, esc, tab, enter )
Adds some keyboard listeners to the page for typical game commands. All input params are callback functions, first 5 are mandatory.

WET.keyListen( 
  enabled => { return true },
  up      => { console.log( 'up' ) },
  left    => { console.log( 'left' ) },
  down    => { console.log( 'down' ) },
  right   => { console.log( 'right' ) },
  crouch  => { console.log( 'crouch' ) },
  space   => { console.log( 'space' ) },
  esc     => { console.log( 'esc' ) },
  tab     => { console.log( 'tab' ) },
  enter   => { console.log( 'enter' ) },
)

keyUpListen( up, left, down, right, crouch )
Adds key-release listeners for switch-keys, all args are callbacks and always enabled.

WET.keyUpListen(
  releaseUp     => { console.log( 'release up' ) },
  releaseLeft   => { console.log( 'release left' ) },
  releaseDown   => { console.log( 'release down' ) },
  releaseRight  => { console.log( 'release right' ) },
  releaseCrouch => { console.log( 'release crouch' ) },
)
