Grammar / Syntax ======================================= No changes. ======================================= II. Implementation Semantics ======================================= ------------------------------------ II.A : Storage and Retrieval of Data ------------------------------------ Any TEXTMAP lump in the described namespaces must be encoded in ISO 8859-1 which as of this writing is the only character encoding supported by ZDoom. ----------------------------------- II.B : Storage Within Archive Files ----------------------------------- In addition to the base specification ZDoom recognizes the following lumps between the TEXTMAP and ENDMAP lumps: BEHAVIOR = contains compiled ACS code DIALOGUE = contains compiled Strife or USDF conversation scripts. ZNODES = Nodes (must be stored as extended GL nodes. Compression is allowed but deprecated for portability reasons.) BLOCKMAP = blockmap. It is recommended not to include this lump in UDMF maps. REJECT = reject table. Recommended use is for special effects only. Lumps starting with 'SCRIPT' are guaranteed to be ignored by ZDoom so they can be used to store ACS and dialogue script sources. -------------------------------- II.C : Implementation Dependence -------------------------------- ZDoom supports all namespaces defined in the base specification and adds two new ones: "ZDoom" "ZDoomTranslated" The only difference between these two namespaces is how line, thing and sector specials are handled: 'ZDoom' uses Hexen type specials which are ZDoom's native implementation. 'ZDoomTranslated' uses Doom-type specials. Such maps have to be processed by a special translator. A special translator is a text lump that defines how Doom-format specials are translated into Hexen-format specials. By default each game defines its own translation table but these can be overridden in MAPINFO. It is the mapper's responsibility to choose the correct translation table for a map. ======================================= III. Standardized Fields ======================================= ZDoom's namespaces implement all fields from the standard, regardless of any restrictions mentioned in the spec. In particular, the 'ZDoomTranslated' namespaces implements thing specials. These will ignore the implicit trigger type and triggering semantics are the same as for native maps. The only field not fully supported is the thing's 'friend' field. ZDoom does not offer MBF's friendly monster implementation and will remap any use of this field to 'strifeally', even for the 'Doom' namespace. In addition to the standard fields, ZDoom defines the following: Note: All fields default to false unless mentioned otherwise. vertex { zfloor = ; // Floor height at this vertex. Only applies to triangular sectors zceiling = ; // Ceiling height at this vertex. Only applies to triangular sectors } linedef { alpha = ; // Translucency of this line, default is 1.0 renderstyle = ; // Render style, can be "translucent" or "add", // default is "translucent". playeruseback = ; // New SPAC flag, true = player can use from back side. anycross = ; // New SPAC flag, true = any non-projectile // crossing will trigger this line monsteractivate = ; // Monsters can trigger this line. // For compatibility only because this flag's // semantics can not be fully reproduced with // explicit trigger flags. blockplayers = ; // Line blocks players' movement. blockeverything = ; // Line blocks everything. firstsideonly = ; // Line can only be triggered from the front side. zoneboundary = ; // Line is a boundary for sound reverb zones. clipmidtex = ; // Line's mid textures are clipped to floor and ceiling. wrapmidtex = ; // Line's mid textures are wrapped. midtex3d = ; // Actors can walk on mid texture. midtex3dimpassible = ;// Used in conjuction with midtex3d - causes the mid // texture to behave like an impassible line (projectiles // pass through it). checkswitchrange = ; // Switches can only be activated when vertically reachable. blockprojectiles = ; // Line blocks all projectiles blockuse = ; // Line blocks all use actions blocksight = ; // Line blocks monster line of sight blockhitscan = ; // Line blocks hitscan attacks locknumber = ; // Line special is locked arg0str = ; // Alternate string-based version of arg0 moreids = ; // Additional line IDs, specified as a space separated list of numbers (e.g. "2 666 1003 4505") transparent = ; // true = line is a Strife transparent line (alpha 0.25) * Note about arg0str For lines with ACS specials (80-86 and 226), if arg0str is present and non-null, it will be used as the name of the script to execute, and arg0 will be ignored. } sidedef { scalex_top = ; // X scale for upper texture, Default = 1.0. scaley_top = ; // y scale for upper texture, Default = 1.0. scalex_mid = ; // X scale for mid texture, Default = 1.0. scaley_mid = ; // y scale for mid texture, Default = 1.0. scalex_bottom = ; // X scale for lower texture, Default = 1.0. scaley_bottom = ; // y scale for lower texture, Default = 1.0. offsetx_top = ; // X offset for upper texture, Default = 0.0. offsety_top = ; // y offset for upper texture, Default = 0.0. offsetx_mid = ; // X offset for mid texture, Default = 0.0. offsety_mid = ; // y offset for mid texture, Default = 0.0. offsetx_bottom = ; // X offset for lower texture, Default = 0.0. offsety_bottom = ; // y offset for lower texture, Default = 0.0. // When global texture offsets are used they will // be added on top of these values. light = ; // This side's light level.

Currently, however, ZDoom assumes this to be true for Doom format maps so any map converter converting to the ZDoomTranslated namespace should set this flag for each tagged sector. } thing { skill# = // Unlike the base spec, # can range from 1-16. class# = // Unlike the base spec, # can range from 1-16. conversation = // Assigns a conversation dialogue to this thing. // Parameter is the conversation ID, 0 meaning none. countsecret = ; // Picking up this actor counts as a secret. arg0str = ; // Alternate string-based version of arg0 gravity = ; // Set per-actor gravity.

Unless mentioned differently the arg being used to define the line ID should be set to 0. The following line specials are affected: 121: Line_SetIdentification, arg 0 208: TranslucentLine, arg0 (arg0 must be preserved) 1: Polyobj_StartLine, arg3 5: Polyobj_ExplicitLine, arg4 181: Plane_Align, arg2 215: Teleport_Line, arg0 222: Scroll_Texture_Model, arg0 (arg0 must be preserved) 160: Sector_3DFloor, arg4 (both uses as high-byte of tag and line ID are not supported in UDMF and must be remapped) Some specials also allow setting the extended flags. These must also be converted to explicitly setting the flags through the defined map fields. This affects the following specials: 121: Line_SetIdentification, arg1 208: TranslucentLine, arg3 These args are to be converted as follows to flags, bit by bit: Bit 0 (Value 1): zoneboundary Bit 1 (Value 2): jumpover Bit 2 (Value 4): blockfloaters Bit 3 (Value 8): clipmidtex Bit 4 (Value 16): wrapmidtex Bit 5 (Value 32): midtex3d Bit 6 (Value 64): checkswitchrange Bit 7 (Value 128): firstsideonly When used in special 208 this arg should be cleared afterward. Special 121 is not being used by UDMF maps in ZDoom and should be completely deleted after conversion. ======================================= Changelog ======================================= 1.1: 27.05.2008 Changed default light mode for sectors and sidedefs to relative and renamed associated properties to avoid having a non-intuitive standard value for the light field.

Standardized whitespace. 1.19 24.02.2012 Added back locknumber property. 1.20 25.02.2012 Added arg0str thing property. 1.21 09.08.2013 Added waterzone sector property. 1.22 12.04.2014 Added transparent line property (to be folded back to core UDMF standard), and health, score, renderstyle, fillcolor, alpha, scale, scalex, scaley, pitch and roll thing properties. 1.24 14.05.2014 Added plane equations for sector slopes. (Please read carefully to ensure proper use!) Changed language describing the DIALOGUE lump to mention USDF as an option. 1.25 19.04.2015 Added 'moreids' for linedefs and sectors. 1.26 05.01.2016 added clarification about character encoding added sector damage properties. =============================================================================== EOF ===============================================================================
