0x15 — script_defaults

Sets script defaults. It calls SetDefaultCharacter, optionally sourcing the character id through GetEventValueForScript, and can call SetDefaultObjectName.

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   |  0x15          |
+----------------+----------------+----------------+----------------+

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
`character`	input	The packed 32-bit character selector word. Its low half is the character id and byte 2 is a secondary class/variant input; see `character_number` and `character_variant`.
`character_variant`	input	Byte 2 of the character selector: a secondary character/class input passed alongside the id.
`default_char`	derived	Argument-byte bit 0: whether a character selector word follows, which then becomes this script's default character. It is a gate, not a character id — `default_char=1` means "a character is given below", not character 1.
`default_object`	derived	Argument-byte bit 1: whether a default object name follows, setting the name later commands act on when they are not given one.
`event_char`	derived	Argument-byte bit 7: read the default character from an event value instead of taking it literally. It changes what the following word means, which is why the line then prints `event_value=` rather than `character=`.
`event_value`	input	Script event-value id that the condition or command reads.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.
