This example attaches a timeline specified with HTML+TIME to an image animated with DirectAnimation. The onOffBehavior property is used to display one image while the animation is running, and to display a different image while the animation is stopped.
Sample Code
<HTML> <HEAD> <TITLE>progressBehavior</TITLE> <XML:NAMESPACE PREFIX="anim"/> <STYLE> .time { behavior: url(#time); } anim\:DA { behavior: url(#default#anim); } </STYLE> <OBJECT ID="time" CLASSID="CLSID:476C391C-3E0D-11D2-B948-00C04FA32195"> </OBJECT> </HEAD> <BODY> <P>Initially, an image of the sun is displayed before the DirectAnimation behavior starts. Five seconds later a new image replaces the image of the sun. The new image fades until it disappears after five seconds of animation. When the animation stops, the original image of the sun reappears.</P> <SPAN ID="spanImg" CLASS="time" t:TIMEACTION="visibility" t:BEGIN="5" t:DUR="5"> </SPAN> <DIV ALIGN="center"> <anim:DA ID="da1" STYLE="width:504; height:126; z-index: -1;" /> </DIV> <BR> <BUTTON onclick="spanImg.beginElement();">Restart</BUTTON> <SCRIPT LANGUAGE="JScript"> <!-- // Assign a variable to the DA statics library m = da1.statics; // Create the DAImages img1 = m.ImportImage("/workshop/graphics/solarsys.gif"); img2 = m.ImportImage("/workshop/graphics/sun.gif"); // Display image 1 while the behavior is running, and // image 2 while it is stopped. img3 = m.Cond(spanImg.onOffBehavior, img1, img2) // Animate the opacity of the image from 100% to 0%, based on the // progress of the time behavior. Use (1 - progress) to get the // proper opacity. img4 = img3.OpacityAnim(m.Sub(m.DANumber(1),spanImg.progressBehavior)); // Set the image of the DA Object to be the final image behavior da1.image = img4; //--> </SCRIPT> </BODY> </HTML>
