0x62 — sprite_config

Reads a bitfield word and consumes variable operands to configure one CSpriteG_Base slot. Proven fields include halfword coordinate/rect values, texture page setup through CSpriteG_Base::MakeTexturePage, floats at sprite offsets 0x24/0x28, and virtual sprite methods from vtable offsets 0x14, 0x1C, 0x3C, 0x48, and 0x4C.

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   |  0x62          |
+----------------+----------------+----------------+----------------+

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

16 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
`arg`	input	Raw handler argument byte from the command header. It is printed only when it differs from the value the named fields already imply, so seeing it means the command uses an unusual argument encoding.
`blend_alpha`	input	Blend parameters applied when the sprite is drawn.
`color`	input	Packed colour word written to the sprite slot.
`control`	derived	Bitmask word choosing which optional payload words follow, in the order the handler tests them. Changing it changes how many words the command carries.
`corner_offset`	input	Offset applied to `corner`.
`mask`	derived	Bitmask selecting which parts of the command apply.
`rotate`	input	Set when rotation is included on this line.
`scale`	input	Set when scale is animated by this line; the scale values follow.
`size`	input	Sprite size as `width,height`.
`sprite_index`	input	Index selecting which `sprite` to act on.
`status_bits`	input	Names of the bits set in the matching packed value.
`texture_page`	input	Which texture page and palette the sprite draws from.
`time_base`	input	Timing base word for the sprite's animation.
`trailing`	input	Words left after the decoded operands, preserved verbatim.
`xy`	input	Top-left corner of the sprite, as `x,y` screen coordinates.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.
