.move.bin (Animation State Machine)

Compiled animation state machines that define how animations blend, transition, and are controlled by game parameters. Part of the Dunia "move" system.

Format — RESOLVED (Sep 2026)

combinedmovefile.bin (FC5/ND/FC6)

u32 version          (64=FC5, 65=ND, 85=FC6)
u32 moveDataSize     (size of animation tree data)
u32 fcbDataSize      (size of FCbn binary object data)
byte[] moveData      (animation trees with classNameType dispatch)
byte[] fcbData       (FCbn: PerMoveResourceInfo + OffsetsHashesArray)

PerMoveResourceInfo (from fcbData): 34951 entries with file paths (.mab animation files), sizes, and rootNodeIds. File paths decode to readable animation paths like animations\legacy\locomotion\transition\panic\run\stops\....

movedef.move.bin (FC4)

u16 version          (22093=FC4 "MV")
u16 unknown
byte[] header        (complex metadata, tree data starts at ~0x523)
byte[] treeData      (classNameType dispatch system)

classNameType dispatch (both formats)

Each node starts with a classNameType byte (7-47) that determines the binary layout:

Type	Class	Description
7	CMoveState	Animation state
8	CMoveBranch	Decision branch
9	CMoveBracket	Bracket node
10	CMoveComparisonOpe	Comparison operator
11	CMoveIntervalOpe	Interval operator
12	CMoveBlendRef	Blend reference
13	CMoveMultiBlendRef	Multi-blend reference
14	CMoveSuspendLayer	Suspend layer
15	CMoveStateRef	State reference
16	CMoveSingleAnim	Single animation
17	CMoveSpeedScaledAnim	Speed-scaled animation
18	CMoveRandomOffsetAnim	Random offset animation
19	CMoveTimeControlledAnim	Time-controlled animation
20	CMoveDoNothing	Do nothing
21	CMoveMotionMatching	Motion matching
22	CMoveMotionMatchingList	Motion matching list (ND/FC6)
23	CMoveMotionMatchingAnim	Motion matching anim (ND/FC6)
26	CMoveFacialAnim	Facial animation
27	CMoveProcedural	Procedural animation
28	CMoveRandomSelector	Random selector
29	CMovePMSSelector	PMS selector
30	CMoveSequence	Sequence
31	CMoveRangeBlend	Range blend
32	CMoveAxialBlend	Axial blend
34	CMoveMultiBlend	Multi-blend
37	CMoveSetGameParams	Set game parameters

Node binary layout

Each node follows: classNameType(1) + header(3: childrenCount, headerA, headerB)

• type-specific data + child offsets(u16 × childrenCount) + padding

Child offsets are direct file byte positions (NOT ×4 as MabTools code suggests). Verified against WDL leak XML hierarchy — children reference positions within the file.

FC4 vs FC5 differences

• FC4 uses simpler state machines (no decision trees or complex blends)
• FC5/ND add decision trees, motion matching, and procedural animation
• FC6 is partial — limited knowledge

Tools

• MabTools (Jakub Mareček) — .move.bin ↔ XML conversion via MoveConvertBin() / MoveConvertXml() in FCBConverter fork
• FCBConverter — can convert the binary object data to XML
