BehaviourOpacity

Description:

[ CCode ( has_construct_function = false , type = "ClutterBehaviour*" ) ]
public BehaviourOpacity (Alpha? alpha, uint8 opacity_start, uint8 opacity_end)

Creates a new BehaviourOpacity object, driven by alpha which controls the opacity property of every actor, making it change in the interval between opacity_start and opacity_end.

If alpha is not null, the Behaviour will take ownership of the Alpha instance. In the case when alpha is null, it can be set later with set_alpha.

Parameters:

alpha	a Alpha instance, or `null`
opacity_start	minimum level of opacity
opacity_end	maximum level of opacity

Returns:

the newly created BehaviourOpacity
