Handler behaviour

Primitive sprite movement helper. It repeatedly calls CPrimitiveAnimation::MovePrimitiveSPRTG for selected helper slots.

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   |  0x6A          |
+----------------+----------------+----------------+----------------+

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

10 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
`call_arg0`	input	Argument 0 passed to the engine call for `call`.
`call_arg3`	input	Argument 3 passed to the engine call for `call`.
`call_arg4`	input	Argument 4 passed to the engine call for `call`.
`call_id`	derived	Identifier selecting which `call` to use.
`float0`	input	Float parameter 0 consumed by this command.
`float1`	input	Float parameter 1 consumed by this command.
`move_kind`	input	Which kind of `move` this line uses.
`primitive_index`	input	Index selecting which `primitive` 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:
