身体的反弹力。值范围从 ``0`` （无反弹）到 ``1``\ （完全反弹）。

\ **注意：**\ 即使将 :ref:`bounce<class_PhysicsMaterial_property_bounce>` 设置为 ``1.0``\ ，由于线性和角度阻尼，一些能量也会随着时间的推移而损失。要让物理体随时间推移保留其所有能量，请将 :ref:`bounce<class_PhysicsMaterial_property_bounce>` 设置为 ``1.0``\ 、将该物体的线性阻尼模式设置为 **Replace**\ （如果可用）、将它的线性阻尼设置为 ``0.0``\ 、它的角度阻尼模式设置为 **Replace**\ （如果可用）、并将它的角度阻尼设置为 ``0.0``\ 。

如果为 ``true``\ ，当两个物体碰撞时，物理引擎将使用标记为“粗糙”的物体的摩擦。如果 ``false``\ ，物理引擎将使用所有碰撞物体的最低摩擦力来代替。如果两个碰撞的对象都为 ``true``\ ，物理引擎将使用最高的摩擦力。
