Line type class (XG)

From Doomsday Wiki
Jump to: navigation, search

The class of an XG line type defines its function. Each type belongs to a single class and thus performs only one function, like initiating a plane move or changing the type of a sector. The Class property of the DED Line Type definition selects the class to use.

Flag definitions

DED definitions of the available line classes are listed below. These flags are defined in Doomsday's standard Flags.ded.

Flag { ID = "ltc_none"; }
Flag { ID = "ltc_chain_sequence"; Value = 0x1; }
Flag { ID = "ltc_plane_move"; Value = 0x2; }
Flag { ID = "ltc_build_stairs"; Value = 0x3; }
Flag { ID = "ltc_damage"; Value = 0x4; }
Flag { ID = "ltc_power"; Value = 0x5; }
Flag { ID = "ltc_line_type"; Value = 0x6; }
Flag { ID = "ltc_sector_type"; Value = 0x7; }
Flag { ID = "ltc_sector_light"; Value = 0x8; }
Flag { ID = "ltc_activate"; Value = 0x9; }
Flag { ID = "ltc_key"; Value = 0xA; }
Flag { ID = "ltc_music"; Value = 0xB; }
Flag { ID = "ltc_sound"; Value = 0x14; }
Flag { ID = "ltc_line_count"; Value = 0xC; }
Flag { ID = "ltc_end_level"; Value = 0xD; }
Flag { ID = "ltc_leave_map"; Value = 0xD; } # Alias for end_level
Flag { ID = "ltc_disable_if_active"; Value = 0xE; }
Flag { ID = "ltc_enable_if_active"; Value = 0xF; }
Flag { ID = "ltc_explode"; Value = 0x10; }
Flag { ID = "ltc_plane_texture"; Value = 0x11; }
Flag { ID = "ltc_plane_material"; Value = 0x11; } # Alias for plane_texture
Flag { ID = "ltc_wall_texture"; Value = 0x12; }
Flag { ID = "ltc_wall_material"; Value = 0x12; } # Alias for wall_texture
Flag { ID = "ltc_command"; Value = 0x13; }
Developer Note: People who will modify the source code and add new line classes should start using numbers from 0x10000. Classes 0 to 0xFFFF will be reserved for standardized use as specified in this document.
