Class: Add
Defined in: animation/utility/index.ts:32
Instant animation that adds a mobject to the scene. Duration is 0 - just introduces the mobject at animation time. Useful for sequencing when you want to add objects at specific points in a timeline.
Like Manim's Scene.add, this does NOT change the mobject's opacity: a
mobject added with a registered (e.g. partially transparent) stroke/fill
opacity keeps it. Use FadeIn/Create if you want the mobject to animate in.

Inherited from
remover
remover:
boolean=false
Defined in: animation/Animation.ts:55
If true, the scene will remove this mobject after the animation finishes. Used by FadeOut (like Python manim's remover=True).

Accessors
startTime
Get Signature
get startTime():
number
Defined in: animation/Animation.ts:220
Get the start time of this animation (set by Timeline)
Returns
number
Set Signature
set startTime(
time):void
Defined in: animation/Animation.ts:227
Set the start time of this animation (used by Timeline)
Parameters
time
number
Returns
void

Methods
begin()
begin():
void
Defined in: animation/utility/index.ts:40
Set up the animation - introduce the mobject without altering its opacity
Returns
void
Overrides
cleanUpFromScene()
cleanUpFromScene(
scene):void
Defined in: animation/Animation.ts:141
Hook called by Scene after the animation finishes, before the next play().
Default: removes mobject if remover is set (FadeOut, Write({remover:true})).
Override for animations that need to mutate scene membership — e.g.
ReplacementTransform swaps source for target.
Parameters
scene
AnimationScene
Returns
void
Inherited from
finish()
finish():
void
Defined in: animation/Animation.ts:131
Called when the animation ends. Subclasses can override to clean up or finalize state.
Returns
void
Inherited from
interpolate()
interpolate(
_alpha):void
Defined in: animation/utility/index.ts:48
No interpolation needed for instant add
Parameters
_alpha
number
Returns
void
Overrides
isFinished()
isFinished():
boolean
Defined in: animation/Animation.ts:181
Check if the animation has finished
Returns
boolean
Inherited from
reset()
reset():
void
Defined in: animation/Animation.ts:190
Reset the animation to its initial state. Restores the mobject to its pre-animation visual state so that re-seeking (especially backward) produces correct results.
Returns
void
Inherited from
update()
update(
_dt,currentTime):void
Defined in: animation/Animation.ts:158
Update the animation for the current frame.
Parameters
_dt
number
Time delta since last frame (unused, but available for subclasses)
currentTime
number
Current time in the timeline
Returns
void
