Instance Members

spine
setLinear(frame: Int): Void

Sets the specified frame to linear interpolation.

Name Type Description
frame Int Between 0 and frameCount - 1, inclusive.
spine
setStepped(frame: Int): Void

Sets the specified frame to stepped interpolation.

Name Type Description
frame Int Between 0 and frameCount - 1, inclusive.
spine
getCurveType(frame: Int): Int

Returns the interpolation type for the specified frame.

Name Type Description
frame Int Between 0 and frameCount - 1, inclusive.
Returns Description
Int {
spine
shrink(bezierCount: Int): Void

Shrinks the storage for Bezier curves, for use when bezierCount (specified in the constructor) was larger than the actual number of Bezier curves.

Name Type
bezierCount Int
spine
setBezier(bezier: Int, frame: Int, value: Int, time1: Float, value1: Float, cx1: Float, cy1: Float, cx2: Float, cy2: Float, time2: Float, value2: Float): Void

Stores the segments for the specified Bezier curve. For timelines that modify multiple values, there may be more than one curve per frame.

Name Type Description
bezier Int The ordinal of this Bezier curve for this timeline, between 0 and bezierCount - 1 (specified in the constructor), inclusive.
frame Int Between 0 and frameCount - 1, inclusive.
value Int The index of the value for the frame this curve is used for.
time1 Float The time for the first key.
value1 Float The value for the first key.
cx1 Float The time for the first Bezier handle.
cy1 Float The value for the first Bezier handle.
cx2 Float The time of the second Bezier handle.
cy2 Float The value for the second Bezier handle.
time2 Float The time for the second key.
value2 Float The value for the second key.
spine
getBezierValue(time: Float, frameIndex: Int, valueOffset: Int, i: Int): Float

Returns the Bezier interpolated value for the specified time.

Name Type Description
time Float
frameIndex Int The index into {
valueOffset Int The offset from frameIndex to the value this curve is used for.
i Int The index of the Bezier segments. See {
Returns
Float
spine
new(frameCount: Int, bezierCount: Int, propertyIds: spine.support.utils.StringArray): Void
Name Type Description
frameCount Int
bezierCount Int The maximum number of Bezier curves. See {
propertyIds spine.support.utils.StringArray Unique identifiers for the properties the timeline modifies.
