Bryn: specified that Elements / Nodes only have tags in version 0x417

'''ASB''' ('''A'''nimation '''S'''equence '''B'''inary) is a file format used to store "animation sequences" for populating "animation slots" of a model. This article is primarily aimed at version 0x41b. In ModuleSystem titles ASB files are typically found in under the "AS" folder, which can appear in the root of a title's romfs or the root of an archive file.

== File Structure ==
ASB assumes little endian. Hashes can be assumed to be 32-bit Murmur3 unless otherwise specified.

Documentation is still sparse, refer to [https://github.com/dt-12345/asb this repository] for more details (names may not match exactly).

If the top bit of the flags is set, then the bottom two bytes of the flags become an index value. If it is not set, then the provided value is value of the parameter. If <code>flags & 1 << 0x18 != 0</code>, then the index is an expression index (EXB) and the normal value field becomes the input value for the expression. If <code>flags & 1 << 0x1e != 0</code>, then the index is a calculation result cache index (this stores the previously evaluated value and calculates the new value from the cached value on subsequent accesses). Note, this is only applicable if the parameter is a float. Otherwise, if <code>flags & 1 << 0x19 != 0</code>, then the index specifies the command data type. 0 is the current frame normalized (i.e. <code>(current_frame - start_frame)/total_duration</code>), 1 and 2 are random float values between 0.0 and 1.0, 3 is an unknown string value, 4 is the command's fade in frame, and 6 is an unknown float value. Note, this only applies if the parameter is a float or a string. In all other cases, the index is a blackboard index and value of the parameter is the value of the corresponding blackboard parameter. For float parameters specifically, <code>flags >> 0x1a & 3</code> specifies the exact parameter source. 0 is a float blackboard parameter while 1, 2, or 3 are a vector3f blackboard parameter with 1, 2, and 3 being the x, y, and z components respectively.

=== Command ===
Defines a command that can be evaluated by an as::Controller to set and play model animations. A command references the start of a behavior tree of elements to be evaluated at runtime. A simple update mode exists to continue playback of animation without always evaluating the command. A bypass mode also exists to play model animations directly from an as::Controller without a defined command.

ASB

2025-04-04T04:53:50Z

Bryn: /* File Header */Removed other title versions from title header section - other versions and what titles use them are listed elsewhere.

'''ASB''' ('''A'''nimation '''S'''equence '''B'''inary) is a file format used to store animation sequences for actors in recent Nintendo EPD games such as ''The Legend of Zelda: Tears of the Kingdom'' and ''Nintendo Switch Sports''. This article is primarily aimed at the version that appears in ''Tears of the Kingdom'' and ''Mario vs Donkey Kong'' (v0x0417). Other ASB versions include 0x304 (''Ring Fit Adventure''), 0x3FB (''Labo Toy-Con 04'' and ''Game Builder Garage''), 0x407 (''Animal Crossing: New Horizons''), 0x40F (''Nintendo Switch Sports''), 0x410 (''Splatoon 3''), 0x418 (''Super Mario Bros. Wonder''), and 0x41A (''Nintendo Switch Online: Playtest Program''). ASB files can be found in the AS folder of the romfs as well as the AS folder of certain pack files.

=== File Structure ===
ASB is a little endian format which consists of node pathways triggered by AS commands. When an AS command is called, it runs the sequence of nodes connected to it which trigger and control animations and animation logic. Nodes are arranged in an array and referenced and accessed by their array index. Despite the presence of animation events in ASB files, these events do not appear to be used by the game.

All string offsets in the file are relative to the start of the string pool and name hashes are 32-bit murmur3 hashes. There are six possible parameter types: string, int (32-bit signed integer), float (32-bit floating point number), bool, vector3f, and pointer (object pointer, this is not actually possible in ASB, only usable in AINB).

Documentation is still sparse, refer to [https://github.com/dt-12345/asb this repository] for more details (names may not match exactly).

|}

If the top bit of the flags is set, then the bottom two bytes of the flags become an index value. If it is not set, then the provided value is value of the parameter. If <code>flags & 1 << 0x18 != 0</code>, then the index is an expression index (EXB) and the normal value field becomes the input value for the expression. If <code>flags & 1 << 0x1e != 0</code>, then the index is a calculation result cache index (this stores the previously evaluated value and calculates the new value from the cached value on subsequent accesses). Note, this is only applicable if the parameter is a float. Otherwise, if <code>flags & 1 << 0x19 != 0</code>, then the index specifies the command data type. 0 is the current frame normalized (i.e. <code>(current_frame - start_frame)/total_duration</code>), 1 and 2 are random float values between 0.0 and 1.0, 3 is an unknown string value, 4 is the command's fade in frame, and 6 is an unknown float value. Note, this only applies if the parameter is a float or a string. In all other cases, the index is a blackboard index and value of the parameter is the value of the corresponding blackboard parameter. For float parameters specifically, <code>flags >> 0x1a & 3</code> specifies the exact parameter source. 0 is a float blackboard parameter while 1, 2, or 3 are a vector3f blackboard parameter with 1, 2, and 3 being the x, y, and z components respectively.

AINB

2025-01-08T22:52:55Z

Bryn:

'''AINB''' ('''AI''' '''N'''ode '''B'''inary) is a file format used for AI and logic in ''Tears of the Kingdom'' as well as other recent Nintendo EPD games. This article is primarily aimed at the version that appears in ''Tears of the Kingdom'' and ''Super Mario Bros. Wonder'' (v0x0407). AINB files can be found in the AI, Logic, and Sequence folders of the romfs as well as within various packs.

=== File Structure ===
AINB is a little endian format similar to most Switch file formats. An AINB file consists of a set of interconnected nodes which act like a syntax tree and control the behavior of actors. These nodes can also be calls to external AINB files (known as modules), allowing AINB files to form entire trees of files. The root file of the tree will have <code>.root.ainb</code> as their extension while each module in the tree will have the extension <code>.module.ainb</code>. There are three primary categories of AINB files in ''TotK'': AI, Logic, and Sequence. For AI and Sequence files, the file's entry point is one or more commands which is linked to one or two child nodes. All nodes are accessed by their index (references to precondition nodes will use their precondition node index which is local to the amount of precondition nodes in the file).

All string offsets in the file are relative to the beginning of the string pool and name hashes are 32-bit murmur3 hashes. There are six possible types for AINB parameters: int (signed 32-bit integer), bool, float (32-bit), vector3f, and pointer. Pointer parameters are pointers to objects.

If the node has any child nodes, the section header is followed by an array of u32 offsets to each of the child node entries. For most nodes, each entry is eight bytes.

|Value
|}
The interpretation of the value depends on the connection type. For input or output connections, the value is a string offset to the parameter name. For standard connections, the value is a string offset to the connection name. For resident update connections, the value is an index into the resident update array. Certain node/connection types will also extend the entry length. Selector-type nodes excluding <code>Element_BoolSelector</code> and <code>Element_F32Selector</code> will have an extra four bytes which stores the condition for to link to the child node. For <code>Element_S32Selector</code>, this is an immediate value. For <code>Element_RandomSelector</code>, this is a weight and for <code>Element_StringSelector</code> it is a u32 string offset. The condition for <code>Element_BoolSelector</code> is the entry's value string. <code>Element_F32Selector</code> adds 24 bytes to each entry, consisting of four eight-byte sub-entries.

The first two bytes of the four bytes at offset 0x00 are the local blackboard parameter index while the last bit is whether or not the index is used or not. The first entry for <code>Element_F32Selector</code> is the minimum value condition while the second entry is the maximum value condition. The last two entries appear to be unused. The last child node entry for Selector-type nodes is the default case. The condition for this case is either a string offset to the string その他 ("Other") or 0 (in the case of <code>Element_S32Selector</code>). Input nodes that are Selector-type nodes also appear to have an additional eight bytes (purpose unknown). <code>Element_Expression</code> have an additional eight bytes per input node (16 bytes in the case of vector3f entries). The purpose of these bytes is unknown.

==== Attachment Parameters ====
This section contains an array of attachments for nodes. This section is preceded by the attachment index array which is an array of u32 indices into the entries in this section. Nodes contain an index into the index array rather than directly into this section. The section contains an array of entries followed by an array of parameter entries.

==== Input/Output Parameters ====
This section contains an array of input and output parameter entries. Similarly to the immediate parameters section, the section begins with u32 relative offsets to the first entry of each data type. However, instead of six offsets, there are 12 - two for each data type (one input, one output). The order of parameters in this section is int input, int output, bool input, bool output, float intput, float output, string input, string output, vector3f input, vector3f output, pointer input, and pointer output.

The default value is an immediate value for the data type (excluding string which is a string offset and pointer which is always an empty four bytes). Pointer entries also have an additional u32 class name offset at offset 0x04, pushing the rest of the entry back by four bytes. If the input child node index is between -32768 and -100, it corresponds to a multi-parameter array index. The multi-parameter index can be calculated as follows: <code>MultiParamIndex = -100 - Index</code>.

==== Resident Update Array ====
This section is an array of entries for resident nodes that are updated mid-node update sequence. The first four bytes specify the number of entries. Each entry is four bytes.

|}
If the first byte of the flags is set to false, then the entry contains another four bytes with a string offset (purpose unknown). By default, the node is scheduled to update pre-next command calculation, however, this can change depending on the flags set. Additionally, Fork and Join nodes behave differently. Fork nodes will append the node to the run array while Join nodes will update the node post-current command calculation.

==== 0x50 Section ====

==== Expression Binary Section ====
The '''EXB''' ('''Ex'''pression '''B'''inary) section is a completely self-contained section that stores custom instructions for a simple command processor. These instructions are grouped into functions that can be called by nodes to perform calculations. Because the section is self-contained, all offsets in this section are local to the section. The EXB section is shared with ASB files ('''A'''nimation '''S'''equence '''B'''inary).

===== Section Structure =====
EXB is essentially its own format and allows for the storage of custom functions in files.

UserFunctions are mapped to a function in the executable by function signature. There are two types of these functions: direct and object. Direct functions are straightforward functions that take up to two arguments and are matched using the function signature. Function objects can take additional arguments and are indexed at runtime.

UserCallback is a class that contains virtual functions providing memory allocation. The input value is passed from the calling node and the output value is passed back.

====== Parameter Region ======
The parameter region is a region that stores the values for parameters values that are too large to fit into two bytes. Parameters that get their values from this section instead store an offset relative to the beginning of the parameter region to the start of the value.

====== Signatures Table ======
This section is an array of u32 string offsets for each function signature.

====== String Pool ======
The string pool is an array of null-terminated strings encoded with UTF-8. All string offsets in this section are relative to the beginning of the string pool.
