Support ProjectAnimations Reference
Complete reference for all animation classes in Fluxion.
Introduction
Animations are the core of Fluxion. They interpolate between two states of a mobject over time, creating smooth transitions.
Basic Animations
Create
Draws a mobject onto the screen.
python
Create(mobject, **kwargs)Example:
python
class CreateExample(Scene):
def construct(self):
circle = Circle()
self.play(Create(circle))Create Animation
FadeIn / FadeOut
Fade mobjects in or out.
python
FadeIn(mobject, **kwargs)
FadeOut(mobject, **kwargs)Write
Animates text being written.
python
Write(text_mobject, **kwargs)Transform Animations
Transform
Morphs one mobject into another.
python
Transform(mobject, target_mobject, **kwargs)ReplacementTransform
Replaces one mobject with another.
python
ReplacementTransform(mobject, target_mobject, **kwargs)Movement Animations
MoveToTarget
Moves a mobject to a target position.
python
mobject.generate_target()
mobject.target.shift(RIGHT * 2)
self.play(MoveToTarget(mobject))Shift
Shifts a mobject by a vector.
python
mobject.animate.shift(UP * 2)Rotation Animations
Rotate
Rotates a mobject.
python
Rotate(mobject, angle, axis=OUT, **kwargs)Rotating
Continuously rotates a mobject.
python
Rotating(mobject, radians=TAU, **kwargs)Growth Animations
GrowFromCenter
Grows a mobject from its center.
python
GrowFromCenter(mobject, **kwargs)GrowFromEdge
Grows a mobject from an edge.
python
GrowFromEdge(mobject, edge, **kwargs)Indication Animations
Indicate
Temporarily highlights a mobject.
python
Indicate(mobject, **kwargs)Flash
Creates a flash effect.
python
Flash(point, **kwargs)Circumscribe
Draws a shape around a mobject.
python
Circumscribe(mobject, **kwargs)Advanced Animations
AnimationGroup
Groups multiple animations.
python
AnimationGroup(*animations, **kwargs)Succession
Plays animations in succession.
python
Succession(*animations, **kwargs)LaggedStart
Starts animations with a lag.
python
LaggedStart(*animations, lag_ratio=0.5, **kwargs)Rate Functions
Control animation timing:
linear- Constant speedsmooth- Ease in and outrush_into- Acceleraterush_from- Deceleratethere_and_back- Go and return
python
self.play(animation, rate_func=smooth)Custom Animations
Create your own animations:
python
class CustomAnimation(Animation):
def interpolate_mobject(self, alpha):
# alpha goes from 0 to 1
self.mobject.set_opacity(alpha)
