This is not a real project to have "docs" :P
But here is an excerpt from my code with values for different door types:
public static inline var EMPTY = 0;
public static inline var NORMAL = 1;
public static inline var ARCHWAY = 2;
public static inline var STAIRS = 3;
public static inline var PORTCULLIS = 4;
public static inline var SPECIAL = 5;
public static inline var SECRET = 6;
public static inline var BARRED = 7;
