Vector JS

A Javascript Implementation of a simple 2D Vector Class, just the basics.
This is strongly inspired by Daniel Shiffmans awesome Book The Nature Of Code. Check it out if you want to learn more about vectors.

To see some possible applications, take a look inside the examples folder or visit the Examples Demo Page.

Creation

There are various ways to create a new Vector:

Create a new Vector pointing to x:2 y:3

var myVector = new Vector(2, 3);

Create a new random but normalized Vector

var myVector = Vector.random2D();

Create a new normalized Vector from a degree value (0-359)

var myVector = Vector.fromDegree(120);

Methods

Got yourself a Vector? This is what you can do with it:

Duplicate

var myVectorCopy = myVector.get();

Subtract another Vector

myVector.sub(yourVector);

Add another Vector

myVector.add(yourVector);

Multiply by 2

myVector.mult(2);

Divide by 2

myVector.div(2);

Get magnitude / length

var magnitude = myVector.mag();

Limit (making sure the Vector is not longer than 8)

myVector.limit(8);

Normalize (scaling the Vector to a length of 1)

myVector.normalize();
