Havok: Difference between revisions

the data section (<code>__data__</code> internally) contains binary data to be serialized into Havok data structures for use by the Havok engine.

The header seems to have a 16-byte alignment and can be 64-bytes (short header) or 80-bytes (long header) in length, depending on if '''Unknown 13''' equals 0 (short header) or 16 (long header).

{| class="wikitable"

|}

There are optional header bytes for a long header. If Unknown 13 equals 16, an additional 16 bytes are added to the header for a total of 80 bytes.

[[File:Havok-class-header-delimits.png|thumb|<code>FF</code> bytes indicate section header boundaries]]

Each section has a 64-byte header which includes the section name, absolute offset to the section start and six relative offsets to segments within the section. All three section headers follow the file header and are delimited by 16 delimiter bytes (<code>0xFF</code>).

|}

There are only three section names: <code>__classnames__</code>, <code>__types__</code> and <code>__data__</code>. The section name is a null-terminated string with a delimiter byte (<code>0xFF</code>) in byte 20.

The absolute offset to the section.

The relative offsets point to different large structures within the section. There are usually a few unique offsets and then multiple duplicated offsets. It is unknown if only unique offsets are significant at this time.
