|Dangerous Dave II tile property format:                                                   |
+------------------------------------------------------------------------------------------+

This covers the data segment that determines the properties of tiles in Dangerous dave and
Shadow Knights. The tile properties 'file' is internal, being stored in the executable at
the following locations:

Dave:   $2841E
Shadow: $

For the purposes of this document we will treat it as an external file, 'TILES.TLI' (As can
be done with Tileinfo and patching in Keen 1-3.)

In a nutshell the file is divided into five 'planes'; each composed of one-byte entries.
Each plane covers a specific property of the tileset, such as blocking-up or general
behavior.

The total size of the tile file is thus (tilenum * 5) bytes

NOTES:


ANIMATION ENTRIES

Animation is disabled, this plane is utterly blank.


BEHAVIOR ENTRIES:

This property is basically how a tile interacts with the player; exit door, kills, etc.
Valid values are between 0-99 (And value higher is 'nothing') The following list describes
what value is what:

00: Nothing  
01: Openable door [If sprite present] [Dave only]
02: Enterable door [Dave only]
13: Kills [Knives]
99: Exit level


BLOCKING ENTRIES:

The possible values here are 0, or not 0 (Usually 1) A value of 0 means Keen can move past
INTO  the x-or-y boundry of a tile (Its left side, bottom, etc) and a value of 1 means he is
stopped from doing so.

One way tiles are thus ones that let him OUT past a boundry, but not in. (But you already
knew that.)
