path-lerp v1.0.2

Path-lerp

A util function that enables you to given a value between 0.0 and 1.0 get the x, y position on a path.

Offers the ability to cache coordinates to a given degree of fidelity.

Example

const PathLerp = require('path-lerp', {
    cacheEnabled: true,
    cacheSensitivity: 2
});

const path = [
    {x: 0, y: 0},
    {x: 1, y: 1},
    {x: 2, y: 2},
    {x: 3, y: 3},
];

const pathLerp = new PathLerp(path);

pathLerp.lerp(0.5); // {x: 1.5, y: 1.5}
pathLerp.lerp(0.75); // {x: 2.25, y: 2.25}
