0x24 — character_virtual_24

Character command with one unresolved virtual call. The handler resolves a character through GetCharacterID/GetCharacterClass2, dispatches a character virtual method, and touches a character sub-manager. The vtable target still needs a dedicated trace before a higher-level label is safe.

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   |  0x24          |
+----------------+----------------+----------------+----------------+

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

6 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
`byte91_mode`	input	Mode selector for `byte91`; the handler branches on it.
`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`.
`mode`	input	Handler path selector taken from the argument byte. The meaning is specific to each command.
`mode_float`	input	Float parameter for `mode`.
`mode_float_word`	input	Raw word behind `mode_float`, consumed by the mode path; its exact role in the virtual call is untraced.
`upper_mode`	input	Mode selector for `upper`; the handler branches on it.

Engine calls

Engine functions this handler was observed calling:

CCharacterManager::GetCharacterClass2(int,unsigned int,const CCharacter*,unsigned int)
CCharacterManager::GetCharacterSubManager(int)
CMotionSwitchData (sub-manager 0x16)
CRadiScript::GetCharacterID(unsigned int&,unsigned int&,unsigned int*,SCR_DATA*,unsigned int)

Bit masks

Masks the handler applies to its argument byte or operand words:

0x0001 0x0003 0x0004
