The most common trick is to animate the location or rotation of an Active physics object as well as the Animated checkbox. When the curve on the Animated property switches to disabled, the physics engine takes over using the object’s last known location, rotation and velocities.
设置各种其他参数的强度动画 ( 机动的 目标速度, 限制等。) 可用于完成各种有趣的结果。
Enabling a constraint during the physics simulation often has dramatic results as the physics engine tries to bring into alignment two objects which are often dramatically out of alignment. It is very common for the affected objects to build up enough kinetic energy to bounce themselves out of camera.
提高仿真稳定性的最简单方法是增加每秒的步数。但是,必须小心,因为执行太多步骤可能会导致问题,使模拟更加不稳定(如果您需要超过1000步,你应该考虑其他方法来提高稳定性)。
增加解算器迭代次数有助于增加约束,并提高物体堆叠稳定性。
最好避免使用小的物体,因为它们当前不稳定。理想情况下,物体的直径应至少为20厘米。如果仍有必要,将碰撞边距设置为0,虽然通常不推荐,但可以帮助使小对象更自然地执行。
由于刚体模拟是动画系统的一部分,它可以影响其它模拟,就像动画系统一样。
为了使其工作,刚体物体需要具有碰撞修改器。只需单击 物理 选项卡中的 碰撞 即可。
在模拟过程中也可以缩放刚体物体。在大多数情况下,这种方法很有效,但有时会导致问题。
