EasingCurve Class

Extends ARchitectObject
Module: AR

Easing Curves describe in which way a AR.PropertyAnimation will change the animated property's value from the start- to the end-value.

The following Easing Curve types are defined (see AR.CONST.EASING_CURVE_TYPE):

Certain Easing Curves can be parametrized with additional values, such as amplitude, period and overshoot.
Amplitude is valid for all easing curves with the type description ending on ELASTIC or BOUNCE (like EASE_IN_ELASTIC or EASE_IN_BOUNCE), and will be ignored for all others.
Overshoot is valid for all easing curves with the type description ending on BACK (like EASE_IN_BACK), and will be ignored for all others.
Period is valid for all easing curves with the type description ending on BOUNCE (like EASE_IN_BOUNCE), and will be ignored for all others.

Example:
var easingCurve = AR.EasingCurve(AR.CONST.EASING_CURVE_TYPE.EASE_IN_BACK, {
  overshoot : 1.70158 //results in a 10% overshoot
});

The same Easing Curve can be instanziated by writing

var easingCurve = AR.EasingCurve("easeInBack", {
  overshoot : 1.70158 //results in a 10% overshoot
});

Constructor

EasingCurve

(
  • type
  • options
)

Parameters:

  • type String
  • options Object optional

    The easing curve can be parametrized with the following values:

Item Index

Methods

Properties

Methods

destroy

()

Inherited from ARchitectObject

Destroys the object.

Properties

amplitude

Number

The amplitude of the elastic effect, the higher the amplitude, the stronger the effect.

In case the amplitude is not set for an easing curve which requires the period value, the default value depends on the easing curve type.

destroyed

Boolean

Inherited from ARchitectObject

Indicates if the object has already been destroyed.

overshoot

Number

The overshoot of the "back"-effect. The higher the value, the stronger the "back"-effect.

In case the overshoot is not set for an easing curve which requires the value, the default value depends on the easing curve type.

period

Number

The period of the elastic effect, the higher the value, the less the frequency of the elastic effect.

In case the period is not set for an easing curve which requires the value, the default value depends on the easing curve type.
