Creating ADB Files
You can create a new ADB file manually in the Animations/Mannequin/ folder (see File Format).
You can also create new ADB files automatically by clicking the '+' button while editing context data in the Mannequin Context Editor. The editor will also prompt you to create an ADB file automatically when you refer to a non-existing one in a Preview Setup File (xxxPreview.xml).
To create new sub-ADBs or edit which rules to use to move fragments into sub-ADBs you use the Mannequin Animation DB Editor.
Internally the system uses indices to refer to Tags and FragmentIDs. Those indices are local to each Tag or FragmentID definition file. It is therefore not safe for the client code to assume that the same FragmentID used in different contexts will have the same value everywhere. As an example, if two different ADBs indirectly refer to the same FragmentID definition file (through the Import element), FragmentIDs defined in this shared file are likely to end up having different values in each context.
Additionally, it is important that all ADBs files used by a controller definition refer to the same FragmentID and Tag definition files. This also means that if you reuse an ADB with two different controller definitions, you need to use the same FragmentID and Tag definition files for both.
Editing ADB Files
You edit the fragments within ADB files by adding/removing Fragments in the Mannequin Fragment Browser. Which ADB file the fragment is in that you are editing is shown at the top of the fragment browser. This is controlled by which ADB is associated with the context you are currently editing (the drop down box at the top of the fragment browser), as well as the sub-ADB rules you set up in the Mannequin Animation DB Editor for that ADB.
Here is a simple example of an ADB file:
The SubADBs section defines the rules used to sort fragments into sub-ADBs. The example shows how fragments with tags "rifle" or "pistol" are stored in separate sub-ADBs. It also shows how fragments with fragmentIDs "script_level1" and "script_level2" go in separate sub-ADBs.
The FragmentList contains the fragments. Individual fragments are Fragment elements inside the element with the name of the FragmentID. The example shows just one fragment, for the FragmentID "idlepose". Within the Fragment element is a list of AnimLayer and ProcLayer elements containing the animation clips and procedural clips respectively. Fragments are sorted according to the priorities of their tags when saving ADB files through the editor.
The FragmentBlendList contains the transitions. Each Fragment element represents one single transition in the editor. Each Variant element maps to the folders in the editor that group similar transitions together with different select times. Each Blend element represents the group of transitions between two FragmentIDs (or the fallback <Any>).
