clone()
clone():
this
Defined in: libs/scene/src/animation/morphtrack.ts:73
Clone this animation track
Returns
this
Overrides
calculateState()
calculateState(
target,currentTime):MorphState
Defined in: libs/scene/src/animation/morphtrack.ts:115
Compute the animation state at the specified time.
Implementations should be pure with respect to inputs: given the same target and currentTime, return the same StateType.
Parameters
target
object
The animated object (used to resolve current baseline if needed).
currentTime
number
Time cursor in seconds within the track's timeline.
Returns
The computed state at currentTime.
Overrides
applyState()
applyState(
node,state):void
Defined in: libs/scene/src/animation/morphtrack.ts:126
Apply a previously computed animation state to the target.
Parameters
node
The animated object to modify.
state
The state to apply.
Returns
void
Overrides
mixState()
mixState(
a,b,t):MorphState
Defined in: libs/scene/src/animation/morphtrack.ts:133
Blend two states into a new state using a weight.
Parameters
a
First state.
b
Second state.
t
number
Blend weight in [0, 1], where 0 yields a and 1 yields b.
Returns
The blended state.
Overrides
getBlendId()
getBlendId():
string
Defined in: libs/scene/src/animation/morphtrack.ts:147
Get the blend identifier for this track.
Tracks with the same blend ID are considered compatible for blending on the same target channel/property.
Returns
string
An identifier used to group compatible tracks for blending.
Overrides
getDuration()
getDuration():
number
Defined in: libs/scene/src/animation/morphtrack.ts:151
Get the intrinsic duration of this track in seconds.
Used by clips to determine overall clip duration and looping behavior.
Returns
number
Track duration (seconds).
Overrides
reset()
reset(
node):void
Defined in: libs/scene/src/animation/morphtrack.ts:155
Reset the track to its initial state for the given target.
Intended to stop playback and rewind the target to the first frame or default state.
Parameters
node
The animated object to reset.
Returns
void
