The Keyframe class defines the value of a property at a specific time during an effect. For example, you can create three keyframes that define the value of a property at the beginning of the effect, at the midpoint of the effect, and at the end of the effect. The effect animates the property change on the target from keyframe to keyframe over the effect duration.

The collection of keyframes for an effect is called the effect's motion path. A motion path can define any number of keyframes. The effect then calculates the value of the property by interpolating between the values specified by two key frames.

Use the MotionPath class to hold the collection of Keyframe objects that represent the motion path of the effect. The MotionPath class specifies the name of the property on the target, and the collection of Keyframes objects specify the values of the property at different times during the effect.

The easing behavior applied to the motion between the previous Keyframe object in motion path and this Keyframe object. By default, the easing is linear, or no easing at all.

Note that the parent effect might have easing applied already over the entire animation. Therefore, if easing per keyframe interval is desired instead, it is necessary to set the overall effect easer to linear easing (spark.effects.easing.Linear) and then set the easer on each Keyframe as appropriate.

Because this property acts on the interval between the previous Keyframe object in a sequence and this Keyframe object, the easer property is ignored on the first Keyframe object in a sequence.

Varsayılan değer şudur Linear.

The time, in milliseconds, at which the effect target for this keyframe should have the value specified by the value property. This time is relative to the starting time of the effect defined with this keyframe.

value

Optional parameter which, if specified, is used to calculate value in this keyframe or the previous one. If value is not set in the previous keyframe, but this keyframe defines both value and valueBy, then value in the previous keyframe is calculated as value in this keyframe minus valueBy in this keyframe.

Similarly, if value in this keyframe is not defined, but valueBy in this keyframe and value in the previous keyframe are both set, then value in this keyframe is calculated as value in the previous keyframe plus valueBy in this keyframe.

valueBy is ignored for the first keyframe in a sequence, since it applies only to the interval preceding a keyframe, and there is no preceding interval for the first keyframe.

Constructor.

Parametreler

	`time:Number` (default = `NaN`) — The time, in milliseconds, at which the effect target of this keyframe should have the value specified by the `value` parameter.

	`value:Object` (default = `null`) — The value that the effect target should have at the given `time`.

	`valueBy:Object` (default = `null`) — Optional parameter which, if provided, causes `value` to be calculated dynamically by adding `valueBy` to the `value` of the previous keyframe in the set of keyframes in a MotionPath object. This value is ignored if this is the first Keyframe in a sequence.
