Angle [0..255] Used in "angle" parameters to Special types:
0 East 32 Northeast
64 North 96 Northwest
128 West 160 Southwest
192 South 224 Southeast
* NOTE that this differs from DOOM/Heretic in that 45/90
degree increments are not used. However, this difference
does _not_ apply for the angles used for the THINGS in
map editing - they are the same as DOOM's (eg: 0 = East,
90 = North, etc.)
Tics Time unit of length 1/35 second. So, 35 tics = 1 second.
Octics Time unit of length 8 tics. So, 8 octics = 1 second.

³ i ³ About This File
ÀÄÄÄÙ
This file was written for those who are interested in the inner workings of
Hexen. It doesn't contain playing tips or information on how to get Hexen
working on your system.
This file is intended to be supplementary to Matt Fell's "Unofficial DOOM
Specs", which probably came with your copy of DOOM or DOOM ][. Wherever
it's relevant, this file refers to a specific section in the DOOM specs (be
sure you have version 1.666!), so it's a good idea to have a copy at hand.

³ i ³ Introduction to Hexen
ÀÄÄÄÙ
Hexen is the sequel to Heretic, Raven Software's first collaboration with id
Software.
[..]
Hexen's major difference from Heretic and DOOM is its programmability. Hexen
features a powerful script language that can be used to create a wide variety
of in-game effects such as traps, puzzles and even earthquakes!

³ 3-0 ³ Hexen Data Structures
ÀÄÄÄÄÄÙ
This section outlines the format of the new data blocks in a Hexen map - the
LINEDEF and THING structures. These structures have changed from the
versions used in DOOM and Heretic.
[DOOM Specs ref]
[3-1] The Hexen LINEDEF structure
---------------------------------
Offset Size Meaning
---------------------------------------------------
0 word the line's start-vertex
2 word the line's end-vertex
4 word line flags (see below)
6 byte special type (see [Specials])
7 5 bytes special arguments
12 word the line's right sidedef number
14 word the line's left sidedef number
[3-1-1] Line Flags
------------------
The following flags are starred with an asterisk if they're new for
Hexen:
Bits Meaning when Set
---------------------------------------------------
0 impassable - the line cannot be crossed.
1 impassable to monsters only.
2 two-sided
3 upper texture is unpegged (drawn from top-down)
4 lower/middle texture is unpegged (drawn from bottom-up)
5 secret - the line appears as impassable on the automap.
6 sound can't travel through the line, but only
for monsters' ears.
7 never draw the line on the auto-map, even with the
map cheat enabled.
8 the line is always drawn on the auto-map, even if it
hasn't been seen by the player.
* 9 the line's special ([3-1]) is repeatable, ie: it can
be activated more than once.
* 10..12 the line's special activation, ie: how the special is
Page 4
HEXEN Specs v0.9 Page 5
activated.
Value Activated when...
---------------------------------------------
0 Player crosses the line
1 Player uses the line with the use key
2 Monster crosses the line
3 Projectile impacts the wall
4 Player pushes the wall
5 Projectile crosses the line
To get the special activation, use the following formula:
activation := (line.flags BITAND 0x1C00) BITSHIFTRIGHT 10
[3-2] The Hexen THING structure
-------------------------------
Offset Size Meaning
---------------------------------------------------
* 0 word thing ID - used in scripts and specials to
identify a THING or a set of THINGs.
2 word x-position on the map
4 word y-position on the map
* 6 word starting altitude on the map - the THING
is created at this altitude above the floor
of the sector it's in when the map is entered,
and is immediately subjected to gravity.
8 word the angle the thing is facing when the map
is entered.
10 word the thing type (see [3-2-2].)
* 12 word thing flags (see [3-2-1].)
14 byte special type (see [Specials]). a thing's
special is activated when the thing is
killed (Monster), destroyed (Tree, Urn, etc.),
or picked up (Artifact, Puzzle Piece.)
15 5 bytes special arguments
[3-2-1] Thing Flags
-------------------
The following flags are starred with an asterisk if they're new for
Hexen:
Bits Meaning when Set
---------------------------------------------------
0 the thing appears on the Easy skill settings (1-2)
1 the thing appears on the Normal skill setting (3)
Page 5
HEXEN Specs v0.9 Page 6
2 the thing appears on the Hard skill settings (4-5)
3 the thing is deaf - it sits around until it's
hurt, or until it sees a player.
* 4 the thing is dormant - it never wakes up until it's
activated using the Thing_Activate() special.
* 5 the thing appears for the Fighter class.
* 6 the thing appears for the Cleric class.
* 7 the thing appears for the Mage class.
* 8 the thing appears in single-player games.
* 9 the thing appears in cooperative games.
* 10 the thing appears in deathmatch games.
Each "thing appears" flag must be set for each condition under which the
thing is to appear. For multi-player games involving more than one
class, a thing that is set for one of the classes involved will also appear
for the other two classes in the game.
For example, if you set the three pieces of the Fighter's sword to appear
for only the Fighter (bit 5 is set) and in Deathmatch (bit 10 is set),
if a Mage or a Cleric is also playing, the pieces of the sword will be
visible to them, too.
[3-2-2] Thing Types
-------------------
Creatures as well as some objects can be activated and/or deactivated with
the ThingActivate and ThingDeactivate line specials.
Creatures will freeze when deactivated and resume when activated.
Activation can also be used to bring a "dormant" creature to life.
If a creature has a special, that special will be activated upon its death.
Also, if the creature is teleported away using the banishment device
(teleport other), the special will be activated and then removed from the
creature.

³ 4-0 ³ Hexen Script Language
ÀÄÄÄÄÄÙ
The Hexen Script Language is called the "Action Code Script", or ACS.
Each map has an ACS file that contains the scripts specific to that map. The
scripts within it are identified using numbers that the general special
ACS_Execute() uses. A script itself can call the ACS_Execute() special
(actually quite common), which will spawn another script that will run
concurrently with the rest of the scripts. A script can also be declared as
OPEN, which will make it run automatically upon entering the map. This is
used for perpetual type effects, level initialization, etc. The compiler
takes the ACS file and produces and object file that is the last lump in the
map WAD (BEHAVIOR).
To create a compiled ACS file from a text script, use the DOS command:
c:\hexen> acs filename [enter]
This command will produce 'filename.o' from 'filename.acs'. The contents of
the output file (filename.o) can be directly used as the BEHAVIOR lump of the
map it's used with.
Map scripts should start with #include "common.acs", which is just...
#include "specials.acs"
#include "defs.acs"
#include "wvars.acs"
The file "specials.acs" defines all the general specials. These are used
within scripts just like function calls. The file "defs.acs" defines a
bunch of constants that are used by the scripts. The file "wvars.acs"
defines all the world variables. It needs to be included by all maps so
they use consistent indexing.
[4-1] Variables and their Scope
--------------------------------
There is only one data type ACS, a 4 byte integer. Use the keyword int to
declare an integer variable. You may also use the keyword str, it is
synonymous with int. It's used to indicate that you'll be using the
variable as a string. The compiler doesn't use string pointers, it uses
string handles, which are just integers.
Declaring a variable is simple. There are two "types" of variable - "str"
and "int":
Page 12
HEXEN Specs v0.9 Page 13
str mystring;
int myint;
or:
str texture, sound;
int i, tid;
* Note: You can't assign a variable in its declaration; you must give it a
value in a different expression.
The SCOPE of a variable is one of World-scope, Map-scope, or Script-scope.
- World-scope variables are global, and can be accessed in any map.
Hexen maintains [n] permanent globals, numbered 0-[n-1]. You must
assign one of the globals a name in order to access it, like this:
world int 5:Grunt;
This tells Hexen to reference world global number 5 whenever it
encounters the name "Grunt".
- Map-scope variables are local to the current map. They must be
declared outside of any script code, but without the world keyword.
These variables can't be accessed in any other map.
- Script-scope variables are local to the current script - they
can't be accessed by any other script or map.
Here's some code that shows the declaration of all three scopes:
world int 3:DungeonAccess; // World-scope
int mapTimer; // Map-scope
script 4 (void)
{
int x, y; // Script-scope
...
}
[4-2] Language Structure
------------------------
Here is a quick reference manual type definition of the language. It
ends with a description of all the internal functions.
Page 13
HEXEN Specs v0.9 Page 14
[4-2-1] Keywords
----------------
The following identifiers are reserved for use as keywords, and may
not be used otherwise:
break
case
const
continue
default
define
do
else
goto
if
include
int
open
print
printbold
restart
script
special
str
suspend
switch
terminate
until
void
while
world
[4-2-2] Comments
----------------
Comments are ignored by the script compiler.
/*
This is a comment.
*/
int a; // And this is a comment
[4-2-3] World-variable definitions
----------------------------------
world int <constant-expression> : <identifier> ;
Page 14
HEXEN Specs v0.9 Page 15
world int <constant-expression> : <identifier> , ... ;
[4-2-4] Map-variable definitions
--------------------------------
Declares a variable local to the current map.
int <identifier> ;
str <identifier> ;
int <identifier> , ... ;
[4-2-5] Include Directive
-------------------------
Includes the source of the specified file and compiles it.
#include <string-literal>
[4-2-5] Define Directive
------------------------
Replaces an identifier with a constant expression.
#define <identifier> <constant-expression>
[4-2-6] Constant Expressions
----------------------------
<integer-constant>:
decimal 200
hexadecimal 0x00a0, 0x00A0
fixed point 32.0, 0.5, 103.329
any radix <radix>_digits
binary 2_01001010
octal 8_072310
decimal 10_50025
hexadecimal 16_00a03f2
[4-2-7] String Literals
-----------------------
<string-literal>: "string"
Page 15
HEXEN Specs v0.9 Page 16
[4-2-6] Script Definitions
--------------------------
To define a script:
<script-definition>:
script <constant-expression> ( <arglist> ) { <statement> }
script <constant-expression> OPEN { <statement> }
eg:
script 10 (void) { ... }
script 5 OPEN { ... }
* Note that OPEN scripts do not take arguments.
[4-2-6] Statements
------------------
<statement>:
<declaration-statement>
<assignment-statement>
<compound-statement>
<switch-statement>
<jump-statement>
<selection-statement>
<iteration-statement>
<function-statement>
<linespecial-statement>
<print-statement>
<control-statement>
[4-2-6-1] Declaration Statements
--------------------------------
Delcaration statements create script variables.
<declaration-statement>:
int <variable> ;
int <variable> , <variable> , ... ;
[4-2-6-1] Assignment Statements
-------------------------------
Assigns an expression to a variable.
Page 16
HEXEN Specs v0.9 Page 17
<assignment-statement>:
<variable> <assignment-operator> <expression> ;
<assignment-operator>:
=
+=
-=
*=
/=
%=
* Note: An assignment of the form V <op>= E is equivalent to V = V <op> E.
For example:
A += 5; is the same as
A = A + 5;
[4-2-6-2] Compound Statements
-----------------------------
<compound-statement>:
{ <statement-list> }
<statement-list>:
<statement> <statement> <...>
[4-2-6-3] Switch Statements
---------------------------
A switch statement evaluates an integral expression and passes control to the
code following the matched case.
<switch-statement>:
switch ( <expression> ) { <labeled-statement-list> }
<labeled-statement>:
case <constant-expression> : <statement>
default : <statement>
Example:
switch (a)
{
case 1: // when a == 1
b = 1; // .. this is executed,
break; // and this breaks out of the switch().
case 2: // when a == 2
Page 17
HEXEN Specs v0.9 Page 18
b = 8; // .. this is executed,
// but there is no break, so it continues to the next
// case, even though a != 3.
case 3: // when a == 3
b = 666; // .. this is executed,
break; // and this breaks out of the switch().
default: // when none of the other cases match,
b = 777; // .. this is executed.
}
* Note for C users: While C only allows integral expressions in a switch
statement, ACS allows full expressions such as "a + 10".
[4-2-6-4] Jump Statements
-------------------------
A jump statement passes control to another portion of the script.
<jump-statement>:
continue ;
break ;
restart ;
[4-2-6-5] Iteration Statements
------------------------------
<iteration-statement>:
while ( <expression> ) <statement>
until ( <expression> ) <statement>
do <statement> while ( <expression> ) ;
do <statement> until ( <expression> ) ;
for ( <assignment-statement> ; <expression> ; <assignment-statement> )
<statement>
The continue, break and restart keywords can be used in an iteration
statement:
- the continue keyword jumps to the end of the last <statement> in the
iteration-statement. The loop continues.
- the break keyword jumps right out of the iteration-statement.
[4-2-6-6] Function Statements
-----------------------------
Page 18
HEXEN Specs v0.9 Page 19
A function statement calls a Hexen internal-function, or a Hexen
linespecial-function.
<function-statement>:
<internal-function> | <linespecial-statement>
<internal-function>:
<identifier> ( <expression> , ... ) ;
<identifier> ( const : <constant-expression> , ... ) ;

³ 6-0 ³ The MAPINFO lump
ÀÄÄÄÄÄÙ
This is a lump in the .WAD that gives attributes to each map. This entry
does not go with each map - there is only one MAPINFO lump in the entire
IWAD. If you include a MAPINFO lump in a PWAD, make sure it's got
information for all the possible maps the player will be entering.
map: Number and name of map [1..60]
warptrans: Actual map number in case maps are not sequential [1..60]
next: Map to teleport to upon exit of timed deathmatch [1..60]
cdtrack: CD track to play during level
cluster: Defines what cluster level belongs to
sky1: Default sky texture; followed by speed
sky2: Alternate sky displayed in Sky2 sectors ; followed by speed
doublesky: parallax sky: sky2 behind sky1
lightning: Keyword indicating use of lightning on the level
flashes from sky1 to sky2 (see also: IndoorLightning special)
fadetable: Lump Name of fade table {fogmap}
Example MapInfo entry:
map 1 "Winnowing Hall"
warptrans 1
next 2
cluster 1
sky1 SKY2 2 ; 2 is the sky scroll speed
sky2 SKY3 0 ; 0 means don't scroll sky
lightning
doublesky
cdtrack 13
Note on "next" integer (for timed deathmatches):
In normal gameplay, there is no linear fashion in which the game
progresses from one level to another; you just go through a teleport
somewhere on a level, and it takes you to somewhere on another
level. For -timer deathmatch, the game needs to know what level to
proceed to because it isn't always just the next higher level.
A note about the WARPTRANS keyword: Maps are edited and named
MAPxx, where xx is a number from 01 to 63. This is the number that
is used from within scripts when a map is referred to, and by the
MAP keyword in the MAPINFO lump. However, the -warp option and the
warping cheat use a different set of numbers. This different set of
numbers is set by the WARPTRANS keyword. By default, the WARPTRANS
value is set to the same number as the map. Our designers starting
Page 25
HEXEN Specs v0.9 Page 26
making maps with numbers that had big gaps between them, and then
made the scripts refer to these numbers, so we needed a way to pack
all the map numbers into a continuous stream for the -warp option.
Also, the accepted range for a WARPTRANS value is 1-31. Makes it
easy when using DM.
Note on "cluster" integer:
The game maps are divided into clusters. When you enter a new cluster, you
can never again visit any of the levels from the previous cluster. This
makes it so each individual save game only needs to backup map archives for
about 6-7 maps, and provides for a milestone marker of sorts for game play,
like an episode -- a Hexen backdrop and some text are given at the end of
each cluster. If you don't enter a cluster, it defaults to 0. The
commercial IWAD separates its 31 maps into 5 clusters.

³ 7-0 ³ PolyObjects
ÀÄÄÄÄÄÙ
Polyobjs are one-sided lines that are built somewhere else on the map, and
then later translated to the desired start spot on the map at level load.
In building polyobjs, two different line specials can be used to determine
the line drawing order:
Polyobj_ExplicitLine(polyNumber, orderNumber, polyMirror, sound);
Polyobj_StartLine(polyNumber, polyMirror, sound);
Each polyobj should have a unique polyNumber, which is used in poly line
specials to refer to a particular polyobj.
polyMirror refers to a second polyobj that will "mirror" all actions of the
first polyobj. For instance, if a polyobj is rotated to the right by 90
degrees, then that polyobj's mirror will rotate left 90 degrees. Note that
having two polyobjs mirror each other is not considered to be a good thing,
but in general won't cause problems because a poly can only do one particular
action at a time. Meaning: if that poly that rotated left by 90 degrees
then mirrored the right-turning polyobj, the right-turning poly would ignore
any attempt to rotate it again, as it would already be being acted upon.
The last parameter to these specials refers to a particular sound type
that should play when the poly is moved/rotated. See the section on
attaching sounds to a moving sector for more info.
Polyobj_StartLine():
A very basic special. Place it on a particular polyobj line, and that line
will be the first line rendered on the polyobj. The rendering order for all
other lines are determined by itterating through to the next line that has a
first point identical to the start line's second point. The third line
rendered will be the next line that has a first point identical to the second
line's second point, and so on and so forth. This method works well for
polyobjs that are convex, and has the advantage of leaving all but one line
free for other line specials.
Polyobj_ExplicitLine:
This special requires a bit more work to use. Each line in the polyobj
defined using this special must use this line special. Then, a value from
1-255 should be placed in orderNumber. This defines the rendering order for
the lines, with a 1 being the first line rendered, and so on. Useful for
non-convex polyobjs, but has the disadvantage of utilizing all line specials
on the poly.
Page 27
HEXEN Specs v0.9 Page 28
[7-1] Polyobj Start Spots and Anchor Points
-------------------------------------------
Each polyobj must have an anchor point, and a startSpot. The anchor is a
thing placed near the polyobj when it's created that defines the origin of
the polyobj, or the point in which it will rotate about. The anchor (and all
polyobj lines) are directly translated to the polyobj startSpot.
Bottom line: The anchor point is the point near the polyobj, and the
startSpot is the point on the actual map that defines the location of the
poly.
There are two different types of startSpots: crushing and non-crushing.
Pretty obvious what the difference is: if the poly strikes an object, it'll
first attempt to move it. If that fails it will either try to damage the
object, or just stop moving depending upon the type of startSpot.
Please note that the ANGLE field of the startSpot and anchor points should be
equal to the polyNumber that was previously defined for that particular
polyobj. The polyobj stuff was done before any of the TID/thing special code
was implimented, so Raven did this temporary hack, which turned permanent, as
the designers had already done a ton of polyobjs, and didn't want to have to
go back and replace them.

³ D ³ Sector Specials
ÀÄÄÄÙ
The following numbers are used in the sector.type field [see DOOM
specs.]:
1 Light_Phased
2 LightSequenceStart
3 LightSequenceSpecial1
4 LightSequenceSpecial2
These specials deal with phased lightning ("moving lights"). Two
different ways to go about doing phased lighting: automatic, or
by-hand. The automatic method is (obviously) more convenient, but
the by-hand method is more flexible. Light_Phased is the by-hand
special. Place it on a sector, then set the sector's lightlevel to a
phase index (0-63). As you place the special on nearby sectors,
increment the index for each sector.
Or, to use the LightSequence specials, just place the LightSequence
special on a sector. Then, for each additional sector, alternate
between LightSequenceSpecial1 & LightSequenceSpecial2.
For instance, if you wanted phased lightning to flow up a staircase,
you could either place Light_Phased on each step, and change the
phase index (lightlevel) accordingly. Or, you could place
LightSequenceStart on the bottom step (and set that step's lightlevel
to something mid-ranged: 80-128 are pretty nice values), and then
let the game calculate the phase indices for each step by placing the
LightSequenceSpecial specials on all other steps. Note that for the
LightSequenceSpecial specials to have proper lighting, set their
lightlevels to zero, which causes it to use the previous sector's
lightlevel. Hence, that "nice value" which was placed on the first
step will iterate through all the other steps. If a step's
lightlevel is not zero, then that value will filter down to all other
steps after it.
26 Stairs_Special1
27 Stairs_Special2
Used by action specials that build stairs.
199 Light_IndoorLightning1
Dimmer effect during lightning flash. Used for indoor areas, which
are normally not affected by lightning.
198 Light_IndoorLightning2
Same as 1, but brighter.

The OR stands for OverRide. As stated before, each poly can only be doing a
single action at a time. This poses a problem with perpetual polyobjs, since
they are already moving, the designer cannot do anything else with them.
However, using these functions the designer can override the code to not
allow a poly to concurrently execute more than one action, and force a poly
to do the other action as well.
