Doom Builder has editing features for different data types of UDMF fields and standard hexen arguments. This is a list of all supported data types: 0 = integer * 1 = float 2 = string 3 = bool 4 = linedeftype (integer) * 5 = sectoreffect (integer) * 6 = texture (string) 7 = flat (string) 8 = angle in degrees (integer) 9 = angle in radians (float) 10 = XXRRGGBB color (integer) 11 = enum option (integer) * 12 = enum bits (integer) * 13 = sector tag (integer) * 14 = thing tag (integer) * 15 = linedef tag (integer) * 16 = enum option (string) - Only types indicates with * are usable for standard hexen args - When no type is specified, the default type is 0 (integer) - Enum types (11, 12 and 16) cannot be used in custom UDMF fields For enum types 11, 12 and 16 there must be an "enum" field that either specifies the values or refers to an existing enum set: enum { 0 = "Yes"; 1 = "No"; } OR enum = "yesno"; Type 16 uses case-sensitive strings for values and can only be used as an option, not as bit flags: enum { translucent = "Translucent"; add = "Add"; }
