beginElementAt method

Starts an element's timeline at the specified time.

Syntax

object.beginElementAt(parentTime)

Parameters

  • parentTime [in]
    Type: double

    A String that specifies the point along the element's parent timeline at which to start playing the element.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The element's timeline will start at the time specified by the beginElementAt method if beginElementAt is invoked at any time before the parent element reaches that specified time. Otherwise, the element's timeline will start immediately. If beginElementAt is invoked on an element's timeline more than once with a value that is the same or less than the previous value used, it will be ignored.

Examples

This example shows how to use the beginElementAt method to start an element's timeline at a specified time.
