manim - Issue in changing the background of a scene in manim

Question

I can't seem to change the camera config in a scene in manim; i put the following code at the top of a scene:

CONFIG = {
    "camera_config":{"background_color": "#003399"}
} 

but the background doesn't change; is there something else needed to change the background?

Answer 1

从 GraphScene 尝试过，但没有成功。然而，起作用的是：

def construct(self):
    self.camera.background_color = WHITE

Answer 2

我不确定我是否应该在这里回答或者是否应该编辑这个问题，无论如何我明白了，这是因为我把这CONFIG行放在了def之后construct(self)
