The body's bounciness. Values range from ``0`` (no bounce) to ``1`` (full bounciness).

\ **Note:** Even with :ref:`bounce<class_PhysicsMaterial_property_bounce>` set to ``1.0``, some energy will be lost over time due to linear and angular damping. To have a physics body that preserves all its energy over time, set :ref:`bounce<class_PhysicsMaterial_property_bounce>` to ``1.0``, the body's linear damp mode to **Replace** (if applicable), its linear damp to ``0.0``, its angular damp mode to **Replace** (if applicable), and its angular damp to ``0.0``.

如果為 ``true``\ ，當兩個物體碰撞時，物理引擎將使用標記為“粗糙”的物體的摩擦。如果 ``false``\ ，物理引擎將使用所有碰撞物體的最低摩擦力來代替。如果兩個碰撞的物件都為 ``true``\ ，物理引擎將使用最高的摩擦力。
