The body's bounciness. Values range from [code]0[/code] (no bounce) to [code]1[/code] (full bounciness).
[b]Note:[/b] Even with [member bounce] set to [code]1.0[/code], some energy will be lost over time due to linear and angular damping.

If [code]true[/code], the body is deactivated when there is no movement, so it will not take part in the simulation until it is awakened by an external force.
