PRActionRotateBy()
Creates an action object of type PRActionTypeRotateBy. When this action is played by an object, that object’s image_angle variable will animate from its current value by the amount given in rotateBy using the easing equation identified by easeId over a duration of durationSecs seconds.
As this is a relative animation, it is possible to alter the object's animating variable in mid-process. The object will adapt to whatever new value is set at each frame (step) update.
Declaration
PRActionRotateBy(rotateBy, easeId, durationSecs)
Parameters
rotateBy
The relative amount that the object's image_angle variable will be changed by the end of the animation.
easeId
The ease ID identifying the easing equation to use when animating the object's variable.
durationSecs
The total length of time (in seconds) that the animation will take before completing. Specifying 0 here will result in an instant change to the final value in 1 frame (step).
Return Value
The created action object.
