vector2d-extended

Installation

With npm do

npm install vector2d-extended

Simple example

Addition of two vectors:

// init application
var vec1, vec2, vec3;

vec1 = Vector2d(10,0);
vec2 = Vector2d(25,30);
vec3 = Vector2d.add(vec1, vec2);

// render loop
vec3.equate(vec1).add(vec2);

Or set the length of the vector:

var vec, newLength;

newLength = 30;
vec = Vector2d(15, 35);

// The usual way
vec.normalize().multiply(newLength);

// Or the way of the gods
vec.length = newLength;
