Support ProjectScenes Reference
Complete reference for Scene classes in Fluxion.
Scene Class
The base class for all Fluxion animations.
python
from fluxion import *
class MyScene(Scene):
def construct(self):
# Your animation code here
passCore Methods
play()
Play one or more animations:
python
self.play(animation)
self.play(animation1, animation2)
self.play(animation, run_time=2, rate_func=smooth)Parameters:
*animations: One or more Animation objectsrun_time: Duration in seconds (default: 1)rate_func: Timing function (linear, smooth, etc.)
wait()
Pause the animation:
python
self.wait() # Wait 1 second
self.wait(2) # Wait 2 seconds
self.wait(0.5) # Wait 0.5 secondsadd()
Add mobjects to the scene instantly:
python
self.add(mobject)
self.add(mob1, mob2, mob3)remove()
Remove mobjects from the scene:
python
self.remove(mobject)
self.remove(mob1, mob2, mob3)Scene Properties
camera
Access the scene's camera:
python
self.camera.background_color = BLACK
self.camera.frame.move_to(RIGHT * 3)mobjects
List of all mobjects in the scene:
python
for mob in self.mobjects:
print(mob)Special Scene Types
ThreeDScene
For 3D animations:
python
class My3DScene(ThreeDScene):
def construct(self):
axes = ThreeDAxes()
self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES)
self.add(axes)3D Methods:
python
# Set camera orientation
self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES)
# Move camera
self.move_camera(phi=60 * DEGREES, theta=45 * DEGREES, run_time=2)
# Begin rotation
self.begin_ambient_camera_rotation(rate=0.1)
# Stop rotation
self.stop_ambient_camera_rotation()VoiceoverScene
For scenes with voiceovers:
python
from fluxion_voiceover import VoiceoverScene
class MyVoiceover(VoiceoverScene):
def construct(self):
with self.voiceover("Hello!") as tracker:
circle = Circle()
self.play(Create(circle), run_time=tracker.duration)Advanced Methods
bring_to_front()
Bring mobjects to front:
python
self.bring_to_front(mobject)bring_to_back()
Send mobjects to back:
python
self.bring_to_back(mobject)get_top_level_mobjects()
Get all top-level mobjects:
python
mobjects = self.get_top_level_mobjects()Updaters
Add dynamic updates:
python
def update_func(mob, dt):
mob.rotate(dt * PI / 2)
mobject.add_updater(update_func)
self.add(mobject)
self.wait(2)
mobject.remove_updater(update_func)Scene Configuration
Setup Method
Override for initialization:
python
class MyScene(Scene):
def setup(self):
# Runs before construct()
self.camera.background_color = "#1a1a1a"
def construct(self):
# Your animation code
passTear Down
Cleanup after scene:
python
def tear_down(self):
# Cleanup code
passRendering Control
Skip Animations
Skip to end of animation:
python
self.skip_animations = TrueTime
Get current scene time:
python
current_time = self.timeScene Examples
Basic Scene
python
class BasicScene(Scene):
def construct(self):
circle = Circle()
self.play(Create(circle))
self.wait()Multi-Object Scene
python
class MultiObject(Scene):
def construct(self):
circle = Circle().shift(LEFT)
square = Square().shift(RIGHT)
self.play(
Create(circle),
Create(square)
)
self.wait()Animated Scene
python
class AnimatedScene(Scene):
def construct(self):
square = Square()
self.play(Create(square))
self.play(square.animate.shift(UP * 2))
self.play(square.animate.rotate(PI / 4))
self.play(square.animate.set_fill(BLUE, opacity=0.5))
self.wait()
