ApplyWave¶

Qualified name: manim.animation.indication.ApplyWave

class ApplyWave(mobject=None, *args, use_override=True, **kwargs)[source]¶

Bases: Homotopy

Send a wave through the Mobject distorting it temporarily.

Parameters:

mobject (Mobject) – The mobject to be distorted.
direction (np.ndarray) – The direction in which the wave nudges points of the shape
amplitude (float) – The distance points of the shape get shifted
wave_func (Callable[[float], float]) – The function defining the shape of one wave flank.
time_width (float) – The length of the wave relative to the width of the mobject.
ripples (int) – The number of ripples of the wave
run_time (float) – The duration of the animation.

        self.play(ApplyWave(tex))
        self.play(ApplyWave(
