Handler behaviour

Camera movement command. It resolves camera objects, target objects, character/SSF targets, stand positions, and calls CRadiCameraSystem::MoveCameraEtc.

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   |  0x54          |
+----------------+----------------+----------------+----------------+

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

15 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
`duration`	input	How long the camera move takes. This is the value itself, not a rendering of another field.
`flag0`	input	Boolean option 0 taken from the handler's argument byte.
`flag1`	input	Boolean option 1 taken from the handler's argument byte.
`source`	derived	Where the command reads its operand from.
`source_character`	input	Source-side `character`, as opposed to the destination.
`source_character_type`	input	Which kind of `source character` this is; the handler branches on it.
`source_control`	input	Bitmask controlling which optional `source` values follow.
`source_explicit_char`	derived	Source-side `explicit char`, as opposed to the destination.
`source_kind`	derived	Which kind of `source` this line uses.
`source_name_source`	derived	Where `source name` is read from.
`source_point`	input	Source-side `point`, as opposed to the destination.
`source_vec`	input	Three-component vector (x, y, z) for `source`.
`target_offset_vec`	input	Three-component vector (x, y, z) for `target offset`.
`target_slot`	input	Destination index into a runtime table owned by this command's subsystem.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.
