Avalon: Data at 60276

60276: Data buffer - room co-ordinate data and pointers


60276	DEFB 0	Maroc's (default) vertical (entry) pixel position when he moves to a new room
60277	DEFB 0	Maroc's horizontal (entry) position when he moves to a new room, in half-character/4-pixel steps
60278	DEFB 0	Maroc's vertical (entry) position when he moves to a new room, in pixels, calculated based on the byte stored at 60276
60279	DEFB 0	Offset for scenery graphics address pointers for 'brick' or 'cavern' type levels (table at 38851) Offset = 0 for brick level scenery (room number <84) Offset = 12 for 'cavern' level scenery (room number >=84) Offset = 0 for brick level foreground scenery items (room number <83) Offset = 8 for cavern level foreground scenery items (room number >=83)
60280	DEFB 0	Room item's horizontal position within current room, in half-character (4 pixel) steps
60281	DEFB 0	Room item's vertical position within current room, in pixels, from top of room area
60282	DEFW 0	Address pointer for room data sets stored at 25001 Also used to store for ROM memory address pointer used to generate foreground scenery objects at 50474
60284	DEFB 0	First room data byte from data banks at 25001
60285	DEFB 0	Multi-purpose byte: Used as a counter to compare with first room data byte (25001) which holds the room size Tunnel length - byte 1 of tunnel data set at 26384
60286	DEFB 0	Multi-purpose: Temporary store for room data bytes at 25001 Data byte x 4 (used to calculate co-ordinates) subsequently stored here at 49691 Counter for number of boundary walls currently on screen in tunnel section
Data relating to doors:
60287	DEFB 0	Door byte: 0 = Back wall door 1 = Right wall door 2 = Left wall door
60288	DEFB 0	Positive/negative offset for door graphic frame (used in routine at 51892) Indicates number of frames (bits 0-2) and opening/closing direction
60289	DEFB 0	Pre-graphic data byte including calculated number of animation frames needed for door. Back wall doors have 4 frames, side wall doors have 5. Calculated at 50091 in door calculation routine.
