The 36 object records of the game, each 20 bytes long. A record whose type byte is 00 is free. The first two records hold the two halves of the player (see ObjectsTable and A78F); the rest hold the scenery, creatures and items of the current room, which BuildRoomScenery fills from the last record downwards. The fields of a record are:

Offset	Contents
00	Object type; indexes the sprite table at SpriteTable and the handler table at ObjectHandlerTable
01	Position on the x axis (the centre of the object)
02	Position on the y axis (the centre of the object)
03	Height above the floor (the bottom of the object)
04	Half the size on the x axis
05	Half the size on the y axis
06	Size on the z axis
07	Flags, see below
08	Room the object belongs to (or the room a door leads to)
09	Speed on the x axis
0A	Speed on the y axis
0B	Speed on the z axis
0C	Collision flags: bit 00 is set when the object hit something on the x axis, bit 01 on the y axis and bit 02 on the z axis (it is on the ground); bit 03 is set while it is jumping; the upper four bits count down the frames after entering a room
0D	Collision state flags used by the handlers
0E	Push from other objects on the x axis
0F	Push from other objects on the y axis
10	Low byte of the address of the entry in the object store at ObjectStore, or handler workspace
11	High byte of the address of the entry in the object store
12	Offset on the x axis from the projected position to the sprite
13	Offset on the y axis from the projected position to the sprite
14 to 16	Handler workspace
17	Handler flags
18	Width in bytes of the sprite last drawn
19	Height of the sprite last drawn
1A	Screen x position of the sprite last drawn
1B	Screen y position of the sprite last drawn, counted from the bottom of the screen
1C to 1F	Copy of 18 to 1B from the previous frame

The flags in byte 07 are:

Bit	Meaning
00	Ignore the walls of the room
01	The object is being moved, so it is ignored by the collision tests
02	The object can be pushed
03	The object can open doors (the player)
04	The object needs drawing
05	The object has moved and its old area needs restoring
06	Mirror the sprite from left to right
07	Flip the sprite upside down
