Properties

threshold

In most cases changing the threshold isn’t needed. In px/ms, default to 0.

deceleration

{Float} the deseleration in px/ms², default to 0.0035.

nbPoints

{Integer} the number of points we use to calculate the kinetic initial values.

delay

{Float} time to consider to calculate the kinetic initial values. In ms, default to 200.

points

List of points use to calculate the kinetic initial values.

timerId

ID of the timer.

Constructor

OpenLayers.Kinetic

Parameters

options

{Object}

Functions

begin

begin: function()

Begins the dragging.

update

update: function( xy )

Updates during the dragging.

Parameters

xy	{OpenLayers.Pixel} The new position.

end

end: function( xy )

Ends the dragging, start the kinetic.

Parameters

xy	{OpenLayers.Pixel} The last position.

Returns

{Object} An object with two properties: “speed”, and “theta”. The “speed” and “theta” values are to be passed to the move function when starting the animation.

move

move: function( info,
callback )

Launch the kinetic move pan.

Parameters

info	{Object} An object with two properties, “speed”, and “theta”. These values are those returned from the “end” call.
callback	{Function} Function called on every step of the animation, receives x, y (values to pan), end (is the last point).
