Class: Skeleton
Represents a skeleton used to play animations.
Constructors
new Skeleton()
new Skeleton(graph: GraphNode): Skeleton
Create a new Skeleton instance.
Parameters
graph
The root GraphNode of the skeleton.
Returns
Properties
looping
looping: boolean = true
Determines whether skeleton is looping its animation.
animation
Get Signature
get animation(): Animation
Gets the animation on the skeleton.
Returns
Set Signature
set animation(value: Animation): void
Sets the animation on the skeleton.
Parameters
value
Returns
void
currentTime
Get Signature
get currentTime(): number
Gets the current time of the currently active animation in seconds.
Returns
number
Set Signature
set currentTime(value: number): void
Sets the current time of the currently active animation in seconds. This value is between zero and the duration of the animation.
Parameters
value
number
Returns
void
numNodes
Get Signature
get numNodes(): number
Gets the number of nodes in the skeleton.
Returns
number
Methods
addTime()
addTime(delta: number): void
Progresses the animation assigned to the specified skeleton by the supplied time delta. If the delta takes the animation passed its end point, if the skeleton is set to loop, the animation will continue from the beginning. Otherwise, the animation's current time will remain at its duration (i.e. the end).
Parameters
delta
number
The time in seconds to progress the skeleton's animation.
Returns
void
blend()
blend(
skel1: Skeleton,
skel2: Skeleton,
alpha: number): void
Blends two skeletons together.
Parameters
skel1
Skeleton holding the first pose to be blended.
skel2
Skeleton holding the second pose to be blended.
alpha
number
The value controlling the interpolation in relation to the two input skeletons. The value is in the range 0 to 1, 0 generating skel1, 1 generating skel2 and anything in between generating a spherical interpolation between the two.
Returns
void
setGraph()
setGraph(graph: GraphNode): void
Links a skeleton to a node hierarchy. The nodes animated skeleton are then subsequently used to drive the local transformation matrices of the node hierarchy.
Parameters
graph
The root node of the graph that the skeleton is to drive.
Returns
void
updateGraph()
updateGraph(): void
Synchronizes the currently linked node hierarchy with the current state of the skeleton. Internally, this function converts the interpolated keyframe at each node in the skeleton into the local transformation matrix at each corresponding node in the linked node hierarchy.
Returns
void
