Avalon: Data at EB82

EB82: Data buffer - room objects


EB82	DEFW $0000	Address pointer to item's data set in object room table at 736F
EB84	DEFB $00	Data set number for object in room interactable objects table at 736F
8 bytes copied here from object data table (736F) at the routine at DE7F
EB85	DEFB $00	Room number of object being dealt with
EB86	DEFB $00	Horizontal (X) position of object in room, in 4-pixel (half-character) steps
EB87	DEFB $00	Vertical (Y) position of object in room, in pixels, from top of room
EB88	DEFB $00	Item properties byte (similar to EB4E) Bit 1 (2) set = Item is not visible Bit 2 (4) set = Item/creature not subject to standard room boundary collision checks (e.g. BATS) Bit 4 (16) set = Item is being carried by servant Bit 6 (64) set = Maroc can pick up the item
EB89	DEFB $00	Object state - starts at 1 for each object, e.g. chest state 1 = closed, 2 = open Each additional object state is stored in an extra 4 byte set
EB8A	DEFB $00	Spell number (or 0 if not a spell) - spell table at 6DFC Start counting with MOVE = 0, SERVANT = 1 etc.
EB8B	DEFB $00	Attribute/colour/value of object Bits 0-3 = INK colour of object (0-7) Bit 4 = object will change colour Bits 5-7 contain the item's value when trading with warlocks - see CE79
EB8C	DEFB $00	Number of additional 4-byte sets for this object
4 additional bytes related to the object's current state. Copied here from the object's data set at 736F by the routine at DE7F
EB8D	DEFB $00	Room item/creature movement pattern byte. Used for moving room items (including set room creatures) in the routine at CBA8 Bit 0 set = room item/creature has a random element to its movement Bit 1 set = room item/creature will try to home in on Maroc's position Bit 2 set = room item/creature is subject to usual room wall collision detection/adjustment (BATS do not have this set)
EB8E	DEFB $00	Event number for items acting on this item - e.g. for a chest, which is opened by a particular key with matching event number Checked in event/collision checks at CC27 Event type 15 = Object that Maroc can collect (or be given by the servant)
EB8F	DEFB $00	Event number to check for this item - e.g. for a key, that opens a particular chest with matching event number As part of event/collision check, also used for energy-affecting objects, e.g. orbs and mushrooms. 254 = energy drain, 253 = energy replenish
EB90	DEFB $00	Graphic number - offset for graphic address table at 97C3 Calculated is [(n-1)*2] + 97C3 A value of 124 (check at CB00) means the object is hidden (e.g. inside a chest) so doesn't need drawing on screen
