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   |  0x59          |
+----------------+----------------+----------------+----------------+

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

14 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
`blend_flag`	derived	Boolean option controlling `blend`.
`duration`	input	Human-readable rendering of the command's duration word. Edit the underlying `duration_word` when it is listed as an input.
`end_color`	input	Packed RGBA8 end colour word; `end_rgba8` beside it shows the four channels.
`flags`	input	Command header flag byte. Bit 0x80 is the keep-going bit: set (the hidden default), the next command runs in the same frame; clear (printed as `yield=1`), the script pauses until the next game update. Other bits are rare and stay as an explicit flags= byte.
`float0`	derived	Float parameter 0 consumed by this command.
`float1`	input	Float parameter 1 consumed by this command.
`float2`	input	Float parameter 2 consumed by this command.
`has_first_float`	derived	Whether `first float` is present on this line.
`has_start_color`	derived	Whether `start color` is present on this line.
`kind`	derived	Which colour this line animates: fog or ambient.
`low`	input	Lower part of the matching packed value.
`mode`	input	Handler path selector taken from the argument byte. The meaning is specific to each command.
`target_slot`	derived	Destination 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.
