alpha
property of a component.
If played manually (outside of a transition) on an object whose
visible
property is set to false, and told to animate
alpha
from zero to a nonzero value, it will set visible
to true as a side-effect of fading it in. When run as part of a
transition, it will respect state-specified values, but may use
the visible
property as well as whether the object
is parented in the before/after states to determine the
values to animate alpha
from and to if alphaFrom
and alphaTo
are not specified for the effect.
