The opacity multiplier applied to the referenced transition.
The opacity multiplier is clamped to the [0, 1] range when set.
Setting a new value overwrites any existing opacity override for that transition.
On a transition between two states, this property fades the transition wire and leaves the arrow solid.
On a self transition, this property fades the transition arrow's border, leaving the arrow head solid.
Getting or setting this property has no effect, and getting it returns 1f, when the
TransitionReference has no associated TransitionReference.Context, such as when it is default.
Throws ObjectDisposedException when you access this property after you call Context.Dispose on the context.
Reduce the opacity of a transition to draw it semi-transparently in the state machine canvas, for example to
de-emphasize a transition that was not taken.
TransitionReference transitionRef = context.GetTransitionReference(transitionID); transitionRef.Opacity = 0.5f;
