Vector2d allows for easy handling of two-dimensionals coordinates and vectors. It’s very flexible, most methods accepts arguments as strings, arrays, hashes or Vector2d objects.

Installation

Install from RubyForge:

sudo gem install vector2d

Install from GitHub:

gem sources -a http://gems.github.com
sudo gem install elektronaut-vector2d

Usage examples

require 'vector2d'

# These are equal
v = Vector2d.new(50, 70)  
v = Vector2d.new('50x70')

v.aspect_ratio # => 0.714285714285714
v.length       # => 86.0232526704263

# Calculations work as expected
v * 2                   # => #<Vector2d:0x5d994 @y=140.0, @x=100.0>
v + Vector2d.new(20,30) # => #<Vector2d:0x59c54 @y=100.0, @x=70.0>

v.constrain_both(64, 64) # => #<Vector2d:0x47e28 @y=64.0, @x=45.7142857142857>
