0x64 — primitive_play_paf

Primitive PAF sequence helper. It resolves a PAF id and sequence index, calls CPrimitiveAnimation::GetPafAddress, CPrimitiveAnimation::PlayPafSequence, and optionally CPrimitiveAnimation::SetOffset.

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   |  0x64          |
+----------------+----------------+----------------+----------------+

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
`has_offset`	derived	Whether `offset` is present on this line.
`paf_id`	input	Identifier selecting which `paf` to use.
`paf_mode`	input	Mode selector for `paf`; the handler branches on it.
`sequence_index`	input	Index selecting which `sequence` to act on.
`slot`	input	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.

Engine calls

Engine functions this handler was observed calling:

CPrimitiveAnimation::GetPafAddress(unsigned int,unsigned int)
CPrimitiveAnimation::PlayPafSequence(CPafSeqInfo*)
CPrimitiveAnimation::SetOffset(unsigned int,short,short)

Bit masks

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

0x0080 0x0003 0x001F 0xFFFF 0x0001
