import { clamp } from 'mm-utils/maths';
const clampedVal = clamp(val, -1, 1);clamp
Clamp a value between two bounds
function clamp(v, min, max);distance
Distance between two points
function distance(x1, y1, x2, y2) lerp
Linear interpolation between two values (lerping)
function lerp(x, y, r)lightenDarkenColor
Lighten or darken a color
function lightenDarkenColor(col, amt)map
Re-maps a number from one range to another
function map(v, start1, stop1, start2, stop2) modAbs
Loop on an index value
function modAbs(index, length)normalize
Normalize a value between two bounds
function normalize(min, max, x)parabola
Remap the 0..1 interval into 0..1 parabola, such that the corners are remaped to 0 and the center to 1 In other words, parabola(0) = parabola(1) = 0, and parabola(1/2) = 1
function parabola(k, x)randomFloat
