Eye of the Beholder Maze Format

ReverseEngineer: Added info about tile-side definition

This page describes the maze format in [[Eye of the Beholder]], which are saved in <tt>.MAZ</tt> files.

The 2D-View is calculated by a map of the "view-cone" for each view direction. The tile-sides which point towards the players direction plus the left/right sides depending on the side of the cones center are used.

{{TODO|Add grid display of "View-Cone"}}

{{TODO|Give general description of the way the format works}}

{{TODO|Add [[Template:Map Infobox]]. Will need a new type for "2D maze viewed in first person 3D"}}

[[Category:Eye of the Beholder]]

Generally all new calculated positions are clamped using binary AND. Example: [New Position] & 0x3FF. This creates a wraparound effect which is used in EOB1 for the Spider-Level for a long hallway which extends the maximum 32 Tiles in the Y-Direction.

The same format is used in Lands of Lore but compressed with [[Westwood LCW|LCW compression]], and using the file extension <tt>.CMZ</tt>.

ReverseEngineer: Created page. With infoformations as well as I can remember them.

Generally all new calculated positions are clamped using binary and. Example: [New Position] & 0x7FF. This creates a wraparound effect which is used in EOB1 for the Spider-Level for a long hallway which extends the maximum 32 Tiles in the Y-Direction. 
The same format is used in Lands of Lore but compressed with type 4 compression and uses the file extension "CMZ".
