AnimationSourceItem Class Reference

Detailed Description

An ActionSource contains a collection of animation source items, which you can get at using ActionSource::GetItems. The AnimationSourceItem class provides access to the animation DataSource (for example, an FCurve) and a target entity such as the Parameter or Cluster which the animation source drives.

One way to create action animation is to create an empty ActionSource and then populate it afterwards using ActionSource::AddSourceItem. In that case you can add a StaticSource as the animation source using AnimationSourceItem::SetAsStatic.

In order to know exactly which type of AnimationSourceItem you are dealing with you can use SIObject::GetType which returns one of the values contained in the ::siAnimationSourceItemType enum.

Example:
Illustrates creating a source and accessing the source items contained in it.
        using namespace XSI;


        Application app;
        Model root = app.GetActiveSceneRoot();

        X3DObject myCube;

        args[2] = 1l;
        args[3] = L"StoredStaticPose";
        args[4] = true;
        args[5] = 1l;

            app.LogMessage(L" The type of animation is " + currItem.GetType());
            //In this case its a static value
            //you can switch on type.

CString GetTarget ( ) const

Returns the complete name of the animation target (the Parameter to which the animation has been applied) as a RelativeName.

Note:
ActionSources store the relative name instead of the FullName of a parameter so actions can be easily copied from one Model to another.
Tip:
In the mixer, you can see this name ("Item Name") by opening the property page of the source (for example, Mixer > Sources > Shape > Point_ClusterClip_source. In the case of a shape source, you need to access Clip::GetMappedItems when you need a current cluster name changed by a designer, because this function returns the original cluster name stored in a Shape Source in the Mixer.
Returns:
The RelativeName (SIObject::GetFullName without the modelname prefix).
Example:
This example illustrates how to create a simple actionsource from some position animation. AnimationSourceItem::Source property is used to get the fcurve source and modify the keys.

Sets the complete name of the object to be animated by this animation source item as a RelativeName.

Note:
ActionSources store the relative name instead of the FullName of a parameter so actions can be easily copied from one Model to another.
Parameters:
in_target The RelativeName (SIObject::GetFullName without the modelname prefix)
Returns:
CStatus::OK success
CStatus::Fail failure
CStatus SetAsStatic ( CValue in_vValue,
StaticSource out_static 
)

Sets the source of the source item as a StaticSource (static value).

Parameters:
in_vValue The value of the AnimationSourceItem.
Return values:
out_static The newly created StaticSource.
Returns:
CStatus::OK success
CStatus::Fail failure
Example:
Illustrates some of the different ways you can work with the value of an AnimationSourceItem's StaticSource, from creating using AddSourceItem and SetAsStaticValue to editing an existing static value using the GetSournce/PutSource combo.
