Constructor Details

#initialize(alpha, x_scale_start, y_scale_start, x_scale_end, y_scale_end) ⇒ Clutter::Behaviour

Creates a new Clutter::BehaviourScale instance.

If alpha is not nil, the Clutter::Behaviour will take ownership of the Clutter::Alpha instance. In the case when alpha is nil, it can be set later with clutter_behaviour_set_alpha().

Parameters:

• alpha (Clutter::Alpha) —

  a Clutter::Alpha instance, or nil

• x_scale_start (Float) —

  initial scale factor on the X axis

• y_scale_start (Float) —

  initial scale factor on the Y axis

• x_scale_end (Float) —

  final scale factor on the X axis

• y_scale_end (Float) —

  final scale factor on the Y axis

Instance Method Details

#get_bounds(x_scale_start, y_scale_start, x_scale_end, y_scale_end) ⇒ nil

Retrieves the bounds used by scale behaviour.

Parameters:

• x_scale_start (Float) —

  return location for the initial scale factor on the X axis, or nil

• y_scale_start (Float) —

  return location for the initial scale factor on the Y axis, or nil

• x_scale_end (Float) —

  return location for the final scale factor on the X axis, or nil

• y_scale_end (Float) —

  return location for the final scale factor on the Y axis, or nil

Returns:

• (nil)

#set_bounds(x_scale_start, y_scale_start, x_scale_end, y_scale_end) ⇒ nil

Sets the bounds used by scale behaviour.

Parameters:

• x_scale_start (Float) —

  initial scale factor on the X axis

• y_scale_start (Float) —

  initial scale factor on the Y axis

• x_scale_end (Float) —

  final scale factor on the X axis

• y_scale_end (Float) —

  final scale factor on the Y axis

Returns:

• (nil)

#x_scale_end ⇒ Float
