title: Directional Lights
body: <p>I'm working on a game idea (2D) that needs directional lights. Basically I want to add light sources that can be moved and the light rays interact with the other bodies on the scene.</p>
  
  <p>What I'm doing right now is some test where using sensors (box2d) and ccDrawLine I could achieve something similar to what I want. Basically I send a bunch of sensors from certain point and with raycast detect collisions, get the end points and draw lines over the sensors.</p>
  
  <p>Just want to get some opinions if this is a good way of doing this or is other better options to build something like this?</p>
  
  <p>Also I would like to know how to make a light effect over this area (sensors area) to provide a better looking light effect. Any ideas?</p>
