0x56 — camera_move_existing

Short camera movement wrapper. It calls CRadiCameraSystem::MoveCameraEtc using the current camera system pointer and an existing RCM_MVINFO pointer from script state. The payload is decoded as repeated x,y,z,duration movement points.

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   |  0x56          |
+----------------+----------------+----------------+----------------+

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

4 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
`move_mode`	input	Mode selector for `move`; the handler branches on it.
`points`	input	The waypoints the camera moves through, in order.
`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.
