There might be a case where you desperately need a quite realistic model of air friction in your game or simulation. Air friction, like another friction, reduces the speed of objects moving in it. Box2D provides a way to cheaply do this using set damping methods (linear and angular). These methods might be quite useful if you just want to show the slowing effect, but It’s not really near accurate to to the correct model of air friction.
So, you’re getting annoyed finding vertex cordinartes for your super complicated physics body and you want someone find that for you? You came to the correct neighborhood!
This tutorial will show how to use PhysicsEditor (a really cool physics body editor!) to create box2d bodies. I presume you have basic knowledge on making bodies manually. If not, I recommend you to try making some. It worth the number of lines you code. You can download this cool Editor here.
