Action method to control the timed rotation of a DisplayObject.

Summary

Constants
  • NONE : uint
  • CW : uint
    • Clockwise rotation.
  • CCW : uint
    • Counter-clockwise rotation.
  • NEAR : uint
    • Clockwise or counter-clockwise rotation to nearest rotation.
Instance methods
  • rotate (inDO:DisplayObject, inDuration:Number, inStartRotation:Number, inEndRotation:Number, inDirection:uint = AQRotate.NONE, inEffect:Function = null) : Function

Constants

CCW

static const CCW:uint = 1 << 2

Counter-clockwise rotation.

CW

static const CW:uint = 1 << 1

Clockwise rotation.

NEAR

static const NEAR:uint = 1 << 3

Clockwise or counter-clockwise rotation to nearest rotation.

NONE

static const NONE:uint

Instance methods

rotate

function rotate(inDO:DisplayObject, inDuration:Number, inStartRotation:Number, inEndRotation:Number, inDirection:uint = AQRotate.NONE, inEffect:Function = null) : Function
Parameters
inDO :DisplayObject to rotate
inDuration :length of rotation in seconds; 0 is used for perpetual animations - use -1 for instant rotation
inStartRotation:the starting rotation in degrees; if NaN the current DisplayObject's rotation will be used
inEndRotation :the end rotation in degrees; if NaN the current DisplayObject's rotation will be used
inDirection :(optional) the rotation direction; either AQRotate.CW (clockwise) or AQRotate.CCW (counter-clockwise) or AQRotate.NEAR (nearest rotation); default CW
inEffect :(optional) an effect function, for instance one of the fl.transitions.easing methods
Example
  • This example rotates a needle in a dial to the location that has been clicked, using the direction of the nearest rotation: 
    var angle:Number = NumberUtils.angle(mouseX - tNeedle.x, mouseY - tNeedle.y);
queue.addAction( AQRotate.rotate, tNeedle, 1, NaN, angle, AQRotate.NEAR );    
@usageNote Bug: passing an inDuration of 0 will result in no rotation at all.
Returns
