Detailed Description

the MaterialDB class managea the material properties

It's not possibile to instantiate it, but it's automatically create when a World is created. For accessing it, use the World::materials() method.
there are some predefined materials:

Default: with default properties of physic engine used

nonCollidable: a material that doesn't collide with anything

Definition at line 63 of file world.h.
