Public Methods

public clearTransition(propertyName: String, time: number): Boolean source

Clear a transistion on the passed property that the specified time lies within.

Params:

Name	Type	Attribute	Description
propertyName	String		The name of the property to clear a transition on.
time	number		A time which lies within the property you're trying to clear.

Return:

Boolean

returns True if a transition is removed, false otherwise.

public clearTransitions(propertyName: String) source

Clear all transistions on the passed property. If no property is defined clear all transitions on the node.

Params:

Name	Type	Attribute	Description
propertyName	String		The name of the property to clear transitions on, if undefined clear all transitions on the node.

public transition(startTime: number, endTime: number, currentValue: number, targetValue: number, propertyName: String): Boolean source

Create a transition on the timeline.

Params:

Name	Type	Attribute	Description
startTime	number		The time at which the transition should start (relative to currentTime of video context).
endTime	number		The time at which the transition should be completed by (relative to currentTime of video context).
currentValue	number		The value to start the transition at.
targetValue	number		The value to transition to by endTime.
propertyName	String		The name of the property to clear transitions on, if undefined default to "mix".

Return:

Boolean

returns True if a transition is successfully added, false otherwise.

public transitionAt(startTime: number, endTime: number, currentValue: number, targetValue: number, propertyName: String): Boolean source

Create a transition on the timeline at an absolute time.

Params:

Name	Type	Attribute	Description
startTime	number		The time at which the transition should start (relative to time 0).
endTime	number		The time at which the transition should be completed by (relative to time 0).
currentValue	number		The value to start the transition at.
targetValue	number		The value to transition to by endTime.
propertyName	String		The name of the property to clear transitions on, if undefined default to "mix".

Return:

Boolean

returns True if a transition is successfully added, false otherwise.
