Handler behaviour

Branches on handler_arg_byte & 0x0F, mutates CRadiCameraSystem/CRLHCamera state, and in traced modes calls CRLHCamera::SetParamFromCamera or CRadiCameraSystem::MoveCameraRail.

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   |  0x51          |
+----------------+----------------+----------------+----------------+

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

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

FieldRoleMeaning
flag4inputBoolean option 4 taken from the handler's argument byte.
flag5inputBoolean option 5 taken from the handler's argument byte.
flag6inputBoolean option 6 taken from the handler's argument byte.
flag7inputBoolean option 7 taken from the handler's argument byte.
modeinputHandler path selector taken from the argument byte. The meaning is specific to each command.
rail_forwardderivedDirection flag for CRadiCameraSystem::MoveCameraRail.
rail_timeinputDuration, in the units this command uses, for rail.
yieldderivedPause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.

Engine calls

Engine functions this handler was observed calling:

  • CCharaDispManager::SetInstantMode()
  • CCharacterManager::GetCharacterSubManager(int)
  • CRLHCamera::SetParamFromCamera()
  • CRadiCameraSystem::MoveCameraRail(bool,float)

Bit masks

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