Here is the code I use to create an animation... what code would I add to call a function when the animation finishes?

function ZoomToDistance(distance)
{
i++;
var keyframes = "0 1";
var timeline = "* ["+distance+"]";

targ = MTSMarkup("Target", "", "Name", "MTSCamera", "Property", "orbd", "Timeline", "T1");
time = MTSMarkup("Time", keyframes);
tili = MTSMarkup("Timeline", timeline, "Name", "T1", "Type", "1D");
tiEl = MTSMarkup("MTSTimeElem", targ+time+tili, "Type", "Keyframe", "Name", "myCameraAnim"+i, "On", "0");
vmp.Execute(tiEl);
vmp.TriggerAnim("myCameraAnim"+i);
}

Does the animator doing the animation exist in the MTX via the <MTSTimeElem> tag? Or is it only written into the mtx dynamically via your javascript?
