/**
|
||||
* SECTION:clutter-behaviour
|
||||
* @Title: ClutterBehaviour
|
||||
* @short_description: Class for providing behaviours to actors
|
||||
* @Deprecated: 1.6: Use clutter_actor_animate(), #ClutterAnimator or
|
||||
* #ClutterState instead
|
||||
*
|
||||
* #ClutterBehaviour is the base class for implementing behaviours. A
|
||||
* behaviour is a controller object for #ClutterActor<!-- -->s; you can
|
||||
* use a behaviour to control one or more properties of an actor (such
|
||||
* as its opacity, or its position). A #ClutterBehaviour is driven by
|
||||
* an "alpha function" stored inside a #ClutterAlpha object; an alpha
|
||||
* function is a function depending solely on time. The alpha function
|
||||
* computes a value which is then applied to the properties of the
|
||||
* actors driven by a behaviour.
|
||||
*
|
||||
* Clutter provides some pre-defined behaviours, like #ClutterBehaviourPath,
|
||||
* which controls the position of a set of actors making them "walk" along
|
||||
* a set of nodes; #ClutterBehaviourOpacity, which controls the opacity
|
||||
* of a set of actors; #ClutterBehaviourScale, which controls the width
|
||||
* and height of a set of actors.
|
||||
*
|
||||
* To visualize the effects of different alpha functions on a
|
||||
* #ClutterBehaviour implementation it is possible to take the
|
||||
* #ClutterBehaviourPath as an example:
|
||||
*
|
||||
* 
|
||||
*
|
||||
* The actors position between the path's end points directly correlates
|
||||
* to the #ClutterAlpha's current alpha value driving the behaviour. With
|
||||
* the #ClutterAlpha's function set to a linear ramp the actor
|
||||
* will follow the path at a constant velocity, but when changing to
|
||||
* a sine wave the actor initially accelerates before quickly
|
||||
* decelerating.
|
||||
*
|
||||
* In order to implement a new behaviour you should subclass #ClutterBehaviour
|
||||
* and override the "alpha_notify" virtual function; inside the overridden
|
||||
* function you should obtain the alpha value from the #ClutterAlpha
|
||||
* instance bound to the behaviour and apply it to the desiderd property
|
||||
* (or properties) of every actor controlled by the behaviour.
|
||||
*
|
||||
* #ClutterBehaviour is available since Clutter 0.2.
|
||||
*
|
||||
* #ClutterBehaviour and its sub-classes have been discouraged sing Clutter
|
||||
* 1.0, and formally deprecated since Clutter 1.6. You should use the
|
||||
* [implicit animation][clutter-actor-animation] support inside #ClutterActor
|
||||
* if you still have code using #ClutterBehaviour.
