No detailed and accurate explanation or tutorial for InteractiveScene

[CaftBotti]

I could not use interactive scene. It has the explanation:

"""
    To select mobjects on screen, hold ctrl and move the mouse to highlight a region,
    or just tap ctrl to select the mobject under the cursor.
    Pressing command + t will toggle between modes where you either select top level
    mobjects part of the scene, or low level pieces.
    Hold 'g' to grab the selection and move it around
    Hold 'h' to drag it constrained in the horizontal direction
    Hold 'v' to drag it constrained in the vertical direction
    Hold 't' to resize selection, adding 'shift' to resize with respect to a corner
    Command + 'c' copies the ids of selections to clipboard
    Command + 'v' will paste either:
        - The copied mobject
        - A Tex mobject based on copied LaTeX
        - A Text mobject based on copied Text
    Command + 'z' restores selection back to its original state
    Command + 's' saves the selected mobjects to file
    """

That is not enough to let me know how to see the window and use my mouse and keyboard.

When i use this code:

class ABC(InteractiveScene):
    def construct(self):
        text = Text('ABC')
        self.play(Write(text))

It says:

Media will be written to c:\beibi\a\media\. You can change this behavior with the --media_dir flag.

   There are no scenes inside that module

But if i add "Scene", it will be strange.

class ABC(InteractiveScene, Scene):
    def construct(self):
        text = Text('ABC')
        self.play(Write(text))

Media will be written to c:\beibi\a\media\. You can change this behavior with the --media_dir flag. And then a window is displayed, but it disappears in an instant. Nothing is displayed. Please tell me how to use interactive scene correctly. Thanks!

It looks like it's trying to write the scene to file, which would be the case if you passed in the -w or -o flag. In those case, it would not be interactive. If you call it with something like manimgl file.py ABC, the default should be the preview the scene in a window, where you can then interact with the window.
