OpenLayers.Tween

Summary

OpenLayers.Tween
Properties
easing	{<OpenLayers.Easing>(Function)} Easing equation used for the animation Defaultly set to OpenLayers.Easing.Expo.easeOut
begin	{Object} Values to start the animation with
finish	{Object} Values to finish the animation with
duration	{int} duration of the tween (number of steps)
callbacks	{Object} An object with start, eachStep and done properties whose values are functions to be call during the animation.
time	{int} Step counter
minFrameRate	{Number} The minimum framerate for animations in frames per second.
startTime	{Number} The timestamp of the first execution step.
animationId	{int} Loop id returned by OpenLayers.Animation.start
playing	{Boolean} Tells if the easing is currently playing
Constructor
OpenLayers.Tween	Creates a Tween.
Functions
start	Plays the Tween, and calls the callback method on each step
stop	Stops the Tween, and calls the done callback Doesn’t do anything if animation is already finished
play	Calls the appropriate easing method

Properties

easing

{<OpenLayers.Easing>(Function)} Easing equation used for the animation Defaultly set to OpenLayers.Easing.Expo.easeOut

begin

{Object} Values to start the animation with

finish

{Object} Values to finish the animation with

duration

{int} duration of the tween (number of steps)

callbacks

{Object} An object with start, eachStep and done properties whose values are functions to be call during the animation. They are passed the current computed value as argument.

time

{int} Step counter

minFrameRate

{Number} The minimum framerate for animations in frames per second. After each step, the time spent in the animation is compared to the calculated time at this frame rate. If the animation runs longer than the calculated time, the next step is skipped. Default is 30.

startTime

{Number} The timestamp of the first execution step. Used for skipping frames

animationId

{int} Loop id returned by OpenLayers.Animation.start

playing

{Boolean} Tells if the easing is currently playing
