[BUG] Can't use camera frame animate

[semikernel]

Please explain the issue you're experiencing (with as much detail as possible):

I can't use

self.play(self.camera.frame.animate.scale(0.5))

It said that

AttributeError: 'ThreeDCamera' object has no attribute 'frame'

I am using manim v18.0, and this camera feature works well in manim

Manim Community v0.18.0

So could I use camera animations by other way else? Thx a lot!

Hello, can you please show the full code? Or at least a minimal working example (MWE)?

Yes of course! The origin code is very simple:

from manim import *  # or: from manimlib import *

from manim_slides import Slide

class BasicExample(Slide):
    def construct(self):

        circle = Circle(radius=3, color=BLUE)
        dot = Dot()
        self.play(GrowFromCenter(circle))
        self.play(self.camera.frame.animate.scale(2))
        self.next_slide()  # Waits user to press continue to go to the next slide
        self.add()
        self.next_slide(loop=True)  # Start loop
        self.play(MoveAlongPath(dot, circle), run_time=2, rate_func=linear)
        self.play(self.camera.frame.animate.scale(0.5))
        self.next_slide()  # This will start a new non-looping slide
        self.play(dot.animate.move_to(ORIGIN))

And it returns that:

Manim Community v0.18.0

AttributeError: 'Camera' object has no attribute 'frame'

I tried manim v13.0 and it still doesn't work.

Hello, can you please show the full code? Or at least a minimal working example (MWE)?

Sorry for that, I confused manim and manimce. In manim Scene camera have attribute frame but in manimCE it should be MovingCameraScene. Sincerely sorry again for wasting your precious time!

No issue! This is what I was going to suppose, it is easy to mix ManimGL and ManmCE code. In general, I would recommend only using ManimCE, because ManimGL gets very infrequent updates...

Closing this as this is not a Manim Slides issue, and it has been solved by using the correct functions / attributes.
