# Component Design Patterns for creating reusable, well-structured Manim components. ## VGroup Subclass Pattern ### Basic Structure ```python class MyComponent(VGroup): """Reusable visualization component""" def __init__(self, param1, param2, **kwargs): super().__init__(**kwargs) # Store parameters self.param1 = param1 self.param2 = param2 # Build component self._build() def _build(self): """Construct the component's mobjects""" # Create child mobjects self.part_a = Circle(radius=self.param1) self.part_b = Square(side_length=self.param2) # Position relative to each other self.part_b.next_to(self.part_a, RIGHT) # Add to self (VGroup) self.add(self.part_a, self.part_b) ``` ### Usage ```python # Create instance component = MyComponent(1.0, 0.5) # It's a VGroup, so all VGroup methods work component.scale(0.5) component.move_to(LEFT * 2) component.set_color(BLUE) # Animate self.play(Create(component)) self.play(component.animate.shift(RIGHT * 3)) ``` ## Real-World Example: Distribution Plot ```python from scipy.stats import norm class DistributionPlot(VGroup): """Self-contained probability distribution visualization""" def __init__( self, func, # Distribution function x_range=(-3, 3), # Domain color=BLUE, show_axes=True, **kwargs ): super().__init__(**kwar
