'''AINB''' ('''AI''' '''N'''ode '''B'''inary) is a file format implementing behavior trees for game-specific code. At time of writing it has only appeared in titles on the ModuleSystem game engine. This article is primarily aimed at the version that appears in ''Tears of the Kingdom,'' ''Super Mario Bros. Wonder, Mario vs Donkey Kong,'' and the original October 2024 version of ''Nintendo Switch Online: Playtest Program'' (v0x407). An older version appears in ''Nintendo Switch Sports'' and ''Splatoon 3'' (v0x404). ModuleSystem provides 3 built-in file categories that appear in their own dedicated folders in a title's romfs, being "AI" for actor behavior, "Logic" for actor ai group behavior, and "Sequence" for scene behavior, individual games are free to create their own file categories.

=== File Structure ===
=== Version Table ===
AINB is little endian. An AINB file defines a set of commands to evaluate a tree of built-in or game-specific node classes. The built-in "Element_ModuleCaller" node and supporting structures allow a "root" AINB file to call out to an external "module" AINB file, module's can call further modules, allowing AINB files to form a tree of tree's. An AINB's file extension typically designates whether it is a root <code>.root.ainb</code> or module <code>.module.ainb</code>. 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 query nodes will use their query node index which is local to the amount of query nodes in the file).

== File Structure ==
AINB assumes little endian. Hashes can be assumed to be 32-bit Murmur3 unless otherwise specified.
 
An AINB file defines a set of commands to evaluate a tree of built-in or game-specific node classes. The built-in "Element_ModuleCaller" node and supporting structures allow a "root" AINB file to call out to an external "module" AINB file, module's can call further modules, allowing AINB files to form a tree of tree's. An AINB's file extension typically designates whether it is a root <code>.root.ainb</code> or module <code>.module.ainb</code>. 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 query nodes will use their query node index which is local to the amount of query 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 data types for AINB parameters: int (signed 32-bit integer), bool, float (32-bit), vector3f, and pointer. Pointer parameters are pointers to objects.

Node type names are official. For UserDefined nodes, node definitions can be found in a node definition files. This file is located at <code>NodeDefinition/Node.Product.[ver].aidefn.byml.zs</code> in the corresponding file category folder.
If the input element id is between -32768 and -100, then the input uses a multi-input. The multi-input id can be calculated as follows: <code>BaseMultiInputIndex = -100 - Index</code>.

==== Local Blackboard Parameters ====
This section contains an array of the Blackboard parameters used by file. These parameters may be sourced from external Blackboards or parameter files. The section begins with a 0x30 byte section header followed by the array of parameters, an array of default values of said parameters, and an array of file references if applicable. The order of parameters is in the order of string, int, float, bool, vector3f, and pointer. The section header contains six entries, one for each type.

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 active node update connections, the value is an index into the active node 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.

The interpretation of the value depends on the connection type. For input or output connections, the value is a string of the parameter name. For standard connections, the value is a string of the connection name. For jump connections, the value is an id into the Jump Table. Elements are free to extend the plug data with their own element specific values. For built-in element selector-types, excluding <code>Element_BoolSelector</code> and <code>Element_F32Selector</code>, an extra four bytes stores data used to select the child plug. 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 string. 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.

=== Blackboard ===
This section contains an array of the Blackboard parameters used by file. These parameters may be sourced from external Blackboards or parameter files. The section begins with a 0x30 byte section header followed by the array of parameters, an array of default values of said parameters, and an array of file references if applicable. The order of parameters is in the order of string, int, float, bool, vector3f, and pointer. The section header contains six entries, one for each type.

The default value entries vary based on the parameter's data type. For int, float, and bool parameters, the entry is a four byte immediate value. String entries are a four byte string value offset. Vector3f entries are 12 bytes. Note that pointer parameters do not have default value entries and do not have default values.

==== Input/Output Parameters ====
This section contains an array of input and output parameter entries. These appear to be canonically referred to as "plugs". Similarly to the property 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>.

==== Active Node Update Array ====
=== Jump ===
This section is an array of entries for updates to the active node array. 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). Otherwise, the entry is considered valid if the first byte equals 1. When processing a node graph, the game maintains an array of active root nodes. When a command calculated, the root node of the command is added to this array and it and its child nodes are calculated recursively. An active node update will change the current active root node to the specified node. This usually happens right before the next command's calculation occurs, but if the top bit is set, then it will occur immediately after the current command's calculation finishes (if the source node is an Element_Join nodes, it will always update the active node post current command calculation). This is primarily used for "subroutines" that run a single time then return to the main execution routine. This system is also used for Element_Fork and Element_Join nodes. An Element_Fork node, unlike normal nodes, will replace the entire current active node array with its array of active node updates (essentially forking execution into multiple different paths). The node at the end of each of these paths will optionally also have an active node update referencing a specific Element_Join node. Each of these nodes will push the Element_Join into the active node array. However, Element_Join nodes have an property parameter called InFlowNum and until it has been pushed onto the array that many times in a single calculation, it will not activate and remain dormant. However, once this threshold is reached, it will begin execution (with a guard to make sure only one of the instances added to the array will execute).
If the first byte of the flags is set to false, then the entry contains another four bytes with a string offset (purpose unknown). Otherwise, the entry is considered valid if the first byte equals 1. When evaluating the behavior trees, the game maintains an array of each root element. When a command is set, the root element of the command is set to this context. A jump will change that root element to the element specified by the jump plug's element id. This usually happens right before the next command's calculation occurs, but if the top bit is set, then it will occur immediately after the current command's calculation finishes (if the source element is an Element_Join, it will always update the root elements post current command calculation). This is primarily used for "subroutines" that run a single time then return to the main execution routine. Element_Fork and Element_Join are the main mechanism to manage multiple root elements. An Element_Fork will replace the current root elements with the element id's of it's jump plugs, possibly "forking" execution into multiple roots. The element at the end of a root element specified by an Element_Fork will optionally have a jump plug referencing a specific Element_Join. Each of these elements will push the Element_Join into the root element array. However, Element_Join has a property parameter called InFlowNum, and until that element has been pushed onto the root element array that many times in a single calculation, it will not activate and remain dormant. However, once this threshold is reached, it will begin execution (with a guard to make sure only one of the instances added to the array will execute).
