Vec2.js

A generic library useful when you need to work with points/vectors in 2d space.

Use

  var a = new Vec2(10, 10), // new keyword
      b = Vec2(100, 10); // call the constructor directly

  console.log(a.distance(b)); // 90

Supported operations

• set
• zero
• negate
• add
• subtract
• multiply
• rotate
• length
• lengthSquared
• distance
• normalize
• equal
• abs
• min
• max
• clamp
• isValid
• skew
• dot
• perpDot
• angleTo
• divide
• toArray
• fromArray

Stuff to Note: most of the Vec2's methods take a returnNew as the last parameter. If passed a truthy value, a new vector will be returned to you. Otherwise the operation will be applied to this and this will be returned.
