0x63 — primitive_anim_slot

Primitive animation slot helper. It selects a slot/range, calls a slot virtual method, and can call CPrimitiveAnimation::DeleteSlot.

Handler behaviour

Primitive animation slot helper. It selects a slot/range, calls a slot virtual method, and can call CPrimitiveAnimation::DeleteSlot.

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   |  0x63          |
+----------------+----------------+----------------+----------------+

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

7 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
`all_slots`	input	Whether the command acts on every slot in the group rather than the start/count range.
`count`	input	How many entries this command carries.
`delete_slot`	input	Index into the runtime table of `delete`.
`end_slot`	derived	Index into the runtime table of `end`.
`group`	input	Which group the target belongs to.
`start_slot`	input	Index into the runtime table of `start`.
`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
