物理与声音

Physics settings of a node can be changed on the Physics tab of the Parameters window. Here you can assign a required body to the selected node and then set it up. 节点的物理设置可以在Parameters窗口的Physics选项卡上进行更改。在这里，您可以将所需的主体分配给选定的节点，然后进行设置。

Physics Settings物理设置

However, a node can participate in physical interactions even if it has no physical body assigned: you can enable collision and intersection detection for node's surfaces on the Node tab of the Parameters window. Some node's surfaces may not participate in collisions and intersections: these options can be enabled on a per-surface basis.但是，即使未分配物理实体，节点也可以参与物理交互：您可以在Parameters窗口的Node选项卡上为节点的表面启用碰撞和 intersection 检测。某些节点的曲面可能不参与碰撞和相交：可以基于每个曲面启用这些选项。

注意

To adjust settings of all physical objects in the scene at once, tweak the global physics-related settings.要一次调整场景中所有物理对象的设置，请调整与全局物理相关的设置。

Friction and Restitution Settings摩擦和恢复设置

This section provides parameters for setting up how the selected surface behaves when colliding with physical bodies and shapes.本节提供用于设置碰撞与物理物体和形状时所选曲面的行为的参数。

Friction

Coefficient of friction for the surface. This coefficient allows to model more rough rubbing of surfaces and is opposite to the body's movement direction. Friction parameter values of both surfaces being in contact are considered. The resulting calculated friction depends on the objects' masses and gravity, and the angle between contacting surfaces. The higher the value, the less tendency the body has to slide.The higher the value, the less tendency the body has to slide. Friction is calculated by the contact between physical bodies.Friction is calculated by the contact between physical bodies. The higher the value, the less tendency the body has to slide.Friction is calculated by the contact between physical bodies.表面的摩擦系数。该系数可以模拟更粗糙的表面摩擦，并且与人体的运动方向相反。Friction两个表面中接触的参数值被考虑。所得的计算出的摩擦取决于物体的质量和重力以及接触表面之间的角度。 The higher the value, the less tendency the body has to slide. 值越高，身体滑动的趋势越少。 Friction is calculated by the contact between physical bodies.摩擦是通过物理物体之间的接触来计算的。

Restitution

Coefficient of restitution for the surface. This coefficient determines the degree of relative kinetic energy retained after a collision. It defines how bouncy the object is by contacting with another object. It depends on the elasticity of the materials of colliding bodies. The simulated restitution, like friction, considers the total value for both objects being in contact. The value of 1.0 models elastic collision. Objects bounce off according to the impulse they get by contact.The value of 1.0 models elastic collision. Objects bounce off according to the impulse they get by contact. The value of 0.0 models inelastic collision. Objects do not bounce at all.The value of 0.0 models inelastic collision. Objects do not bounce at all. Restitution is calculated by the contact between physical bodies.Restitution is calculated by the contact between physical bodies. The value of 1.0 models elastic collision. Objects bounce off according to the impulse they get by contact.The value of 0.0 models inelastic collision. Objects do not bounce at all.Restitution is calculated by the contact between physical bodies.表面恢复系数。该系数确定了碰撞后保留的相对动能的程度。它通过与另一个对象接触来定义对象的弹性。它取决于碰撞体材料的弹性。模拟的恢复（如摩擦力）会考虑两个物体接触的总值。 The value of 1.0 models elastic collision. Objects bounce off according to the impulse they get by contact.1.0的值模拟弹性碰撞。物体根据它们通过接触获得的冲动反弹。 The value of 0.0 models inelastic collision. Objects do not bounce at all.0.0的值用于模拟非弹性碰撞。物体根本不反弹。 Restitution is calculated by the contact between physical bodies.恢复是通过身体之间的接触来计算的。
