Как анимировать функции в ursina?

Question

[LINEAGE]

Как я могу добавить анимацию в данный пример, чтобы ось вращалась без моего участия и клавиш по заданной траектории ?

from ursina import *


app = Ursina()

origin = Entity(model='cube', scale=(0.2, 0.2, 0.2))

Entity(model='cube', parent=origin, color=color.red  , position=(5, 0, 0), scale=(10, 0.5, 0.5))
Entity(model='cube', parent=origin, color=color.green, position=(0, 5, 0), scale=(0.5, 10, 0.5))
Entity(model='cube', parent=origin, color=color.blue , position=(0, 0, 5), scale=(0.5, 0.5, 10))

x_handle = Entity()
y_handle = Entity()
z_handle = Entity()


def switch_parent(entity, parent):
    old_world_rotation = entity.world_rotation
    entity.parent = parent
    entity.world_rotation = old_world_rotation


def update():
    old_parent = origin.parent
    switch_parent(origin, x_handle)
    x_handle.rotation_x += held_keys['q'] * 50 * time.dt
    x_handle.rotation_x -= held_keys['a'] * 50 * time.dt

    switch_parent(origin, y_handle)
    y_handle.rotation_y += held_keys['w'] * 50 * time.dt
    y_handle.rotation_y -= held_keys['s'] * 50 * time.dt

    switch_parent(origin, z_handle)
    z_handle.rotation_z += held_keys['e'] * 50 * time.dt
    z_handle.rotation_z -= held_keys['d'] * 50 * time.dt

    switch_parent(origin, old_parent)


app.run()

rotation_animation = animation.sequence(
    animation.create_animation('rotation_x', 0, 360, duration=2, curve=animation.curve.linear),
    animation.create_animation('rotation_x', 360, 0, duration=2, curve=animation.curve.linear),
    loop=True
)

x_handle.animate(rotation_animation)
