Detailed Description

MaterialDB class.

\

Motivation

this object allows to manage the material properties

Description

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

Warnings
