=== File Structure ===
=== 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, 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).

==== Attachment Parameters ====
==== 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.

==== Immediate Parameters ====
==== Immediate Parameters ====
This section contains an array of immediate parameters for nodes. The section begins with a six u32 relative offsets to the first entry for each data type. The data type order for this section is int, bool, float, string, vector3f, and pointer.

|Value
|}
The value is an immediate value for the data type (excluding string which is a string offset and pointer which doesn't store a value). Pointer entries also have an additional u32 class name offset at offset 0x04, pushing the flags to offset 0x08.

==== Input/Output Parameters ====
==== 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.

|Default Value
|}
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>.
