public void Update(
	TimeSpan deltaTime
)

Public Sub Update ( 
	deltaTime As TimeSpan
)

public:
void Update(
	TimeSpan deltaTime
)

member Update : 
        deltaTime : TimeSpan -> unit 

Parameters

deltaTime

Type: SystemTimeSpan
The elapsed time since the last update. (If deltaTime is negative, this method does nothing. It does not reverse the animations.)

The method Update(TimeSpan) advances all animations and computes the animation values. Note however, that the new animation values are not yet applied to the animated properties. ApplyAnimations needs to be called to write the new animation values!

Similarly, completion events (see Completed) are recorded, but are not yet triggered. Completion events are also triggered in ApplyAnimations!
