Skeleton
Represents a skeleton used to play animations.
Summary
Properties
| animation | Animation currently assigned to skeleton. |
| currentTime | Current time of currently active animation in seconds. |
| looping | Determines whether skeleton is looping its animation. |
| numNodes | Read-only property that returns number of nodes of a skeleton. |
Methods
| addTime | Progresses the animation assigned to the specified skeleton by the supplied time delta. |
| blend | Blends two skeletons together. |
| setGraph | Links a skeleton to a node hierarchy. |
| updateGraph | Synchronizes the currently linked node hierarchy with the current state of the skeleton. |
Details
Constructor
Skeleton(graph)
Create a new Skeleton instance.
Parameters
| graph | GraphNode | The root GraphNode of the skeleton. |
Properties
Current time of currently active animation in seconds. This value is between zero and the duration of the animation.
Methods
addTime(delta)
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. |
blend(skel1, skel2, alpha)
Blends two skeletons together.
Parameters
| skel1 | Skeleton | Skeleton holding the first pose to be blended. |
| skel2 | Skeleton | 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. |
setGraph(graph)
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 | GraphNode | The root node of the graph that the skeleton is to drive. |
updateGraph()
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.
