0x22 — character_attach_render

Resolves a character, may call CCharacterManager::AttachData(CCharacter*, unsigned char), toggles no-render behavior through character/SSF methods, and calls CCharacterManager::InhibitionCharacter(CCharacter*).

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   |  0x22          |
+----------------+----------------+----------------+----------------+

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

5 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
`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`.
`no_render`	derived	No-render boolean applied through the SSF handler or character byte; argument-byte bit 7 when data is already attached.
`no_render_bit`	derived	Single bit of `no render`.
`no_render_with_child`	derived	Whether child objects are included with `no render with`.
`sub_manager_flag`	derived	Boolean option controlling `sub manager`.
