MobjectUpdateUtils

manimlib.mobject.mobject_update_utils.assert_is_mobject_method(method)

判断 method 是否是 Mobject 的方法

---

manimlib.mobject.mobject_update_utils.always(method, *args, **kwargs)

一直调用 method，传入 *args, **kwargs

---

manimlib.mobject.mobject_update_utils.f_always(method, *arg_generators, **kwargs)

与 always 类似，但是传入的多个 arg_generators 是可调用对象，用于生成参数

---

manimlib.mobject.mobject_update_utils.always_redraw(func: Callable[…, Mobject], *args, **kwargs) → Mobject

始终重复调用 func 生成新物体

---

manimlib.mobject.mobject_update_utils.always_shift(mobject: Mobject, direction: np.ndarray = array([1., 0., 0.]), rate: float = 0.1) → Mobject

将 mobject 始终向 direction 方向移动，速度为 rate

---

manimlib.mobject.mobject_update_utils.always_rotate(mobject: manimlib.mobject.mobject.Mobject, rate: float = 0.3490658503988659, **kwargs) → manimlib.mobject.mobject.Mobject

将 mobject 始终旋转

---

manimlib.mobject.mobject_update_utils.turn_animation_into_updater(animation: Animation, cycle: bool = False, **kwargs) → Mobject

将 animation 转化为对执行动画对象的 updater

• cycle 为 True 时循环执行，否则只执行一次

---

manimlib.mobject.mobject_update_utils.cycle_animation(animation: Animation, **kwargs) → Mobject

默认保持循环的 turn_animation_into_updater
