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.
