0x65 — primitive_stop_paf

Primitive PAF stop helper. It resolves a PAF id through CPrimitiveAnimation::GetPafAddress and calls CPrimitiveAnimation::StopPafSequence.

Handler behaviour

Primitive PAF stop helper. It resolves a PAF id through CPrimitiveAnimation::GetPafAddress and calls CPrimitiveAnimation::StopPafSequence.

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   |  0x65          |
+----------------+----------------+----------------+----------------+

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

5 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
`paf_id`	derived	Identifier selecting which `paf` to use.
`paf_mode`	input	Mode selector for `paf`; the handler branches on it.
`paf_raw`	input	Raw field preserved verbatim; its meaning is not yet traced.
`raw_high`	input	Upper half of a packed word, preserved verbatim because its meaning is not yet traced.
`slot`	input	Index into a runtime table owned by this command's subsystem.
