0x26 — character_attach_parent

Parent attach/collision helper. It resolves one or two characters, searches SSF names, and calls CCharacterManager::AttachParent, CBackGround::AttachParent, or CCharacterCollision::SetCollisionAttribute.

Handler behaviour

Encoding

The command header is one 32-bit word, as described in §3 Instruction encoding:

 31            24 23            16 15             8 7              0
+----------------+----------------+----------------+----------------+
|  flags         |  argument byte |  extra words   |  0x26          |
+----------------+----------------+----------------+----------------+

Bits 8–15 give the number of 32-bit operand words that follow. Bits 16–23 are handed to the handler as a bitfield; on character commands bit 0 normally says whether a character selector word is present. Bit 31 is the keep-going bit.

Operand fields

11 documented fields. input fields are read from the command's operand words; derived fields are computed from other fields rather than stored separately.

Field	Role	Meaning
`attach_mode`	input	Mode selector for `attach`; the handler branches on it.
`background`	input	Set when the command targets the background rather than a character.
`background_attach_flag`	input	Boolean option controlling `background attach`.
`character`	input	The packed 32-bit character selector word. Its low half is the character id and byte 2 is a secondary class/variant input; see `character_number` and `character_variant`.
`name`	input	Object or animation name this line acts on, as text. The engine reads it as a NUL-terminated string; `name_fill` covers the bytes after the terminator.
`name_source`	input	Selects where a name operand comes from, such as an inline four-word string.
`parent`	input	The object being attached to.
`parent_character`	derived	Low half of the parent selector: the parent's character id.
`parent_source`	input	Where `parent` is read from.
`parent_variant`	derived	Byte 2 of the parent selector: a secondary class input for the parent.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.
