Error when using Code Mobject with OpenGL renderer in v0.19.0 #4163
Description
Description of bug / unexpected behavior
Below error is displayed when we render a Code mobject using opengl renderer. The same code works as expected when we use the cairo renderer.
Error:
TypeError: Only values of type VMobject can be added as
submobjects of Code, but the value Paragraph of 1
submobjects (at index 0) is of type Paragraph.
Expected behavior
The Code Mobject should work with the new OpenGL renderer
How to reproduce the issue
Copy below code in testing.py file.
Code for reproducing the problem
from manim import *
class CodeFromString(Scene):
def construct(self):
code = "import this"
rendered_code = Code(
code_string=code,
language="python",
background="window",
background_config={"stroke_color": "maroon"},
)
self.add(rendered_code)Now, run the code using opengl renderer.
manim testing.py -p --renderer=openglIt throws error with opengl. But, if we use cairo, it works as expected without error.
manim testing.py -p --renderer=cairoAdditional media files
