57015: Create data set for interactable room object and copy item/graphic data into it
Used by the routine at 50218.
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 60227, including graphics data for the object
  • Copies this data into a room item data set at 31744
57015 LD A,4 Graphic type = 4 (interactable object)
57017 LD (60227),A
57020 LD A,(60292) Data set number for interactable object - from object table at 29551
57023 LD (60230),A
57026 LD HL,(60290) Address pointer to the beginning of this interactable object's data set
57029 LD (60228),HL
57032 LD A,(60294) Horizontal (X) position of object in room, in 4-pixel (half-character) steps
57035 LD (60232),A
57038 LD A,(60295) Vertical (Y) position of object in room, in pixels, from top of room
57041 LD (60234),A
57044 LD A,64 64 signifies item in 'standard' room (254/255 for tunnel room items)
57046 LD (60235),A
57049 LD DE,0 Set vertical and horizontal speed of item to zero
57052 LD (60236),DE
57056 LD (60237),DE
57060 LD A,(60296) Copy item properties byte into data buffer
57063 LD (60238),A
57066 LD A,1 Graphic address frame offset = n-1 (= 0, no offset)
57068 LD (60240),A
57071 LD A,(60304) Graphics number for this item (offset for address pointer in graphics table starting at 38851)
57074 CALL 57538 Set up graphics for this interactable object
57077 CALL 57520 Copy item data buffer (60227) into a data set at 31744
