Level BigStuff Table (Class 7)
L17 is a table describing big items in real-world levels.
Cyberspace levels may re-use "big stuff" entries for further software entries. These entries need to be interpreted differently. See Software.
Level BigStuff Entry (16 bytes)
0000 [6]byte Level object prefix
0006 [10]byte BigStuff Info
Displays
There are several big items that are capable of displaying (animated) content. They reuse the following common types:
Display Info (10 bytes)
0000 int16 Frame count
0002 int16 Loop type
0004 int16 Alternation type
0006 int16 Picture source
0008 int16 Alternate picture source
Animated screens are also controlled by the Loop Configuration. If not, they use their own loop type.
Loop Type (1 byte)
0x00 Forward
0x01 Forward/Backward
0x02 Backward
0x03 Forward/Backward
Other values have been found as well, without effect; The engine defaults to forward looping.
** Alternation Type** (1 byte)
0x00 Don't alternate
0x03 Alternate randomly
Not all alternate source combinations work properly. Commonly it is used to alternate to a text.
Picture Source (2 bytes)
This field specifies what shall be shown. It has the following cases:
0x0000 .. 0x00F5 Image frames, offset from resource 0x0141
0x00F6 Static fading into SHODAN's face
0x00F7 Unknown (only found to display static)
0x00F8 .. 0x00FF Surveillance screens 0 .. 7
0x0100 .. 0x017E Text message from resource 0x0877
0x017F Random number for CPU rooms, level 1-6 before destroying nodes.
0x0180 .. 0x01FF Text message, scrolling vertically
For surveillance screens, the sources of screens 0-7 are specified in the Surveillance Sources Table.
The following big items support displays: 7/0/6 (TV), 7/0/7 (COMPUTER MONITOR), 7/2/6 (SCREEN, small), 7/2/8 (SCREEN, large), 7/2/9 (SCREEN, medium), with variation: 7/5/5 (CONTROL PANEL), 7/5/6 (CONTROL PEDESTAL) (see below)
Electronics 7/0/x
Apart from some displays, nothing special
Furniture 7/1/x
Cabinets 7/1/2
Cabinet Data (10 bytes)
0000 [2]byte Unused
0002 [2]int16 Object index
0006 [4]byte Unused
Cabinets can contain up to two objects.
Texturable furniture 7/1/5, 7/1/7, 7/1/8 (chairs and couches)
Texturable Furniture Data (10 bytes)
0000 [6]byte Unused
0006 int16 Texture index
0008 [2]byte Unused
If Texture index is not zero, it specifies the alternate texture to use for the "main" faces of the furniture.
Surfaces 7/2/x
These are big objects that are flat and should be placed at another surface.
Words 7/2/3
Words BigStuff Data (10 bytes)
0000 int16 Text index (within resource 0x0868)
0002 int16 Font and size (bits 0-3 are font, 4-7 are size)
0004 int16 Colour (palette index, 0 defaults to red)
0006 [4]byte Unused
Texture Maps 7/2/7
Texture map big stuff (10 bytes)
0000 [6]byte Unused
0006 int16 Texture index
0008 [2]byte Unused
Texture maps allow to place one tile from the level texture list at any arbitrary position.
Lighting 7/3/x
Medical equipment 7/4/x
Control Pedestals (buttons only) 7/4/0
These can trigger an object if used.
Button Control Pedestal Info (10 bytes)
0000 [2]byte Unused
0002 int16 Trigger object index
0004 [6]byte Unused
Surgery Machines 7/4/3
Surgery Machine Info (10 bytes)
0000 [2]byte Unused
0002 byte Broken state; 0x00 = OK, 0xE7 = broken
0003 [2]byte Unused
0005 byte Broken message index; Broken default: 0x61
0006 [4]byte Unused
With all bytes zero, the surgery machine works normally.
When the Broken state field is set to a certain value (the game has 0xE7 for the one on level 2, though some other work, too), then the machine wouldn't work. When not working, the message identified with Broken message index is displayed in the HUD. (0x61 = "This machine is broken").
Textureable Furniture 7/4/5 (chairs)
These have the same layout as the general textureable furniture (see above).
Science and security equipment 7/5/x
Security Cameras 7/5/4
Security Camera Info (10 bytes)
0000 [2]byte Unused
0002 byte Panning switch; 0x00: stationary, 0x01: panning
0003 [7]byte Unused
Control Pedestals (with display) 7/5/5, 7/5/6
Control pedestals are similar to displays regarding the source of the display. Instead of having different loop options, they trigger an object if used.
Display Control Pedestal Info (10 bytes)
0000 int16 Frame count
0002 int16 Trigger object index
0004 int16 Alternation type
0006 int16 Picture source
0008 int16 Alternate picture source
Garden big stuff 7/6/x
Bridges 7/7/x
Solid Bridges 7/7/0, 7/7/1
Solid Bridge Info (10 bytes)
0000 [2]byte Unused
0002 byte Size. Bits 0-3: X, bits 4-7: Y
0003 byte Height. 0 is default, level height units otherwise.
0004 byte Top/Bottom texture
0005 byte Side texture
0006 [4]byte Unused
The size fields are defined as 0: 3D model default, 4: tile width.
The texture fields have bit 7 set to indicate texture from level texture list. If 0, the other 7 bits index
into citmat.res.
If either textures are to be taken from the level list, the object description will be that of the textures. If a texture is to be taken from citmat.res, the texture index must be > 0, otherwise it will still be the first level texture, even if bit 7 is 0.
Force Bridges 7/7/7, 7/7/8, 7/7/9
Force Bridge Info (10 bytes)
0000 [2]byte Unused
0002 byte Size. Bits 0-3: X, bits 4-7: Y -- see above
0003 byte Height. 0 is default, level height units otherwise.
0004 [2]byte Unused
0006 byte Colour
0007 [3]byte Unused
Object 7/7/8 is a placeholder for force bridges that have not been activated yet. These objects are invisible and are made to force bridges with the use of trigger action 24.
Force bridges of type 7/7/9 differ from the typical ones (7/7/7) in having a default height of zero and no animation when switched from type 8. They furthermore need a size explicitly set.
The engine supports several different values for Colour. Used values are 0x00 for red and 0xFE for green.
Not all 256 colour possibilities have been tested, many resulted in dark red tones or solid colours. Usable variants were found from
0xF7and above.
