0x4A — position_vibration_param

Position-vibration parameter command: a direct CVibrationVector::SetParam wrapper. Selector bits and the first control word are named where the handler trace proves them; the remaining branch payload is preserved byte-exact.

Handler behaviour

Position-vibration parameter command: a direct CVibrationVector::SetParam wrapper. Selector bits and the first control word are named where the handler trace proves them; the remaining branch payload is preserved byte-exact.

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   |  0x4A          |
+----------------+----------------+----------------+----------------+

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

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

FieldRoleMeaning
attrinputPOSVIB attribute word passed to CVibrationVector::SetParam.
attr_modederivedMode selector for attr; the handler branches on it.
enableinputEnable flag passed to CVibrationVector::SetParam.

Engine calls

Engine functions this handler was observed calling:

  • CVibrationVector::SetParam(POSVIB_ATTR,float,float,float,float,float,float,float)
  • CVibrationVector::SetParam(POSVIB_ATTR,unsigned int,float,float,float,float,float,float)

Bit masks

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