/* This example shows how to use soft bodies.
2
 *
3
 * Soft bodies have an attribute to change how much it will
4
 * deforms when colliding. It's called "hardness", and can
5
 * be set to any value between 0.0 (soft) and 1.0 (hard).
6
 * By default, all the soft bodies are hard (1.0).
7
 *
8
 * This example will make a box and a sphere collide
9
 * many times against the floor and will be placed at
10
 * top of the screen again. They will have their hardness
11
 * modified each time, going from the default to a very
12
 * soft state.
13
 *
14
 * It can be tested with edje_player
15
 * $ edje_player physics_soft_bodies.edj
