Used by the routine at C42A.
An interactable object has been found in the room Maroc is entering.
This routine:
  • Sets some data for the object in the data buffer at EB43, including graphics data for the object
  • Copies this data into a room item data set at 7C00
DEB7 LD A,$04 Graphic type = 4 (interactable object)
DEB9 LD ($EB43),A
DEBC LD A,($EB84) Data set number for interactable object - from object table at 736F
DEBF LD ($EB46),A
DEC2 LD HL,($EB82) Address pointer to the beginning of this interactable object's data set
DEC5 LD ($EB44),HL
DEC8 LD A,($EB86) Horizontal (X) position of object in room, in 4-pixel (half-character) steps
DECB LD ($EB48),A
DECE LD A,($EB87) Vertical (Y) position of object in room, in pixels, from top of room
DED1 LD ($EB4A),A
DED4 LD A,$40 64 signifies item in 'standard' room (254/255 for tunnel room items)
DED6 LD ($EB4B),A
DED9 LD DE,$0000 Set vertical and horizontal speed of item to zero
DEDC LD ($EB4C),DE
DEE0 LD ($EB4D),DE
DEE4 LD A,($EB88) Copy item properties byte into data buffer
DEE7 LD ($EB4E),A
DEEA LD A,$01 Graphic address frame offset = n-1 (= 0, no offset)
DEEC LD ($EB50),A
DEEF LD A,($EB90) Graphics number for this item (offset for address pointer in graphics table starting at 97C3)
DEF2 CALL $E0C2 Set up graphics for this interactable object
DEF5 CALL $E0B0 Copy item data buffer (EB43) into a data set at 7C00
