Migrating from v0.19.0 to v0.20.0
This constitutes a list of all the changes needed to migrate your code to work with the latest version of Manim
Manager
If you ever used Scene.render, you must replace it with {class}.Manager.
Original code:
scene = SceneClass()
scene.render()
should be changed to:
with Manager(SceneClass) as manager:
manager.render()
If you are a plugin author that subclasses Scene and changed Scene.render, you should migrate
your code to use the specific public methods on {class}.Manager instead.
ThreeDScene and Camera
ThreeDScene has been completely removed, and all of its functionality has been replaced
with methods on {class}.Camera, which can be accessed via {attr}.Scene.camera.
For example, the following code
class MyScene(ThreeDScene):
def construct(self):
t = Text("Hello")
self.add_fixed_in_frame_mobjects(t)
self.begin_ambient_camera_rotation()
self.wait(3)
should be changed to
# change ThreeDScene -> Scene
class MyScene(Scene):
def construct(self):
t = Text("Hello")
# add_fixed_in_frame_mobjects() no longer exists.
# Now you must use Mobject.fix_in_frame() manually for each Mobject.
t.fix_in_frame()
self.add(t)
# access the method on the camera
self.camera.begin_ambient_rotation()
self.add(self.camera)
self.wait(3)
Animation
Animation.interpolate_mobject has been combined into Animation.interpolate.
Methods Animation._setup_scene and Animation.clean_up_from_scene have been removed
in favor of Animation.begin and Animation.finish. If you need to access the scene,
you can use a simple buffer to communicate. Note that this buffer cannot access
methods on the {class}.Scene, but can only do basic actions like {meth}.Scene.add,
{meth}.Scene.remove, and {meth}.Scene.replace.
For example, the following code:
class MyAnimation(Animation):
def begin(self) -> None:
self._sqrs = VGroup(Square())
def _setup_scene(self, scene: Scene) -> None:
scene.add(self._sqrs)
self.scene = scene
def interpolate_mobject(self, alpha: float) -> None:
sqr = Square().move_to((alpha, 0, 0))
self._sqrs.add(sqr)
self.scene.add(sqr)
def clean_up_from_scene(self, scene: Scene) -> None:
scene.remove(self._sqrs)
should be changed to
class MyAnimation(Animation):
def begin(self) -> None:
self._sqrs = VGroup(Square())
self.buffer.add(self._sqrs)
def interpolate(self, alpha: float) -> None:
sqr = Square().move_to((alpha, 0, 0))
self._sqrs.add(sqr)
self.buffer.add(sqr)
# tell the scene to empty the buffer
self.apply_buffer = True
def finish(self) -> None:
self.buffer.remove(self._sqrs)
