2.1:Constants

Constants

This is a comprehensive list of all constants that can be used in SOCs and Lua scripts. Constants are special keywords recognized by SRB2, such as FRACUNIT and TICRATE, which represent a specific, unchangeable integer number. In Lua, these must always be written in the correct case as given in this article (or in linked articles). SOC, however, is case-insensitive and allows all constants to be written in any case whatsoever. Many groups of constants are identifiable by certain prefixes in their names – for example, all primary Object flags have the MF_ prefix, while all secondary Object flags have the MF2_ prefix instead.

Note Due to the sheer number of constants available in SRB2 altogether, not all of them can be listed here. For convenience, this article provides links to other articles on the SRB2 Wiki already covering specific groups of constants, where they may be explained in more detail than this article can give.

Miscellaneous constants

Name	Value	Description
FRACUNIT	1<<FRACBITS (1<<16, or 65536)	The basic unit of measurement for lengths, speeds, Object scales and sometimes angles. Values for these measurements are interpreted as fixed-point numbers with FRACUNIT as the base unit, i.e., FRACUNIT represents one unit (or in some cases one pixel), 2*FRACUNIT represents 2.0 units, FRACUNIT/2 represents 0.5 units, and so on.
FRACBITS	16	The number of bits to shift up to convert integers to fixed-point numbers in FRACUNIT scale, or the number of bits to shift down for vice versa. This constant is used to define the value of FRACUNIT itself – modifying the value of FRACBITS in the source code would also modify FRACUNIT's value. Note that bit-shifting an integer by FRACBITS in either direction is equivalent to multiplication or division by FRACUNIT – i.e., x<<FRACBITS is the same as x*FRACUNIT, and x>>FRACBITS is the same as x/FRACUNIT.
TICRATE	35	The number of tics in a second, i.e., anything multiplied by this value is a measurement in seconds.
RING_DIST	512*FRACUNIT	The maximum distance that rings can be from players with an Attraction Shield to be attracted to them. This is also used by the homing attack character ability as the maximum distance an enemy, spring or monitor can be to able to home in on it.
PUSHACCEL	2*FRACUNIT	The speed at which pushable Objects with MF2_SLIDEPUSH will be pushed.
MODID	12	The executable's Mod ID. In SRB2 v2.1, 12 is the default value for this constant.
CODEBASE	210	The SRB2 version number the executable is based on. In SRB2 v2.1, 210 is the default value for this constant.
VERSION	201	The game's version number.
SUBVERSION	21	The game's sub-version number.
FLOATSPEED	FRACUNIT*4	Vertical movement speed for Objects with MF_FLOAT.
MAXSTEPMOVE	24*FRACUNIT	The maximum height an Object can step up/down without being blocked by a wall or falling down.
USERANGE	64*FRACUNIT	Doom's Use button effect range. Unused in SRB2.
MELEERANGE	64*FRACUNIT	Doom's melee attack range. Used in SRB2 by P_CheckMeleeRange and P_SkimCheckMeleeRange.
MISSILERANGE	32*64*FRACUNIT	Doom's missile attack range. Used in SRB2 by A_UnidusBall.
ONFLOORZ	INT32_MIN	Used by the map Thing spawning code to signify that the Thing's Z position is on the sector's floor. This is corrected to the appropriate height in P_SpawnMobj for newly spawned Objects.
ONCEILINGZ	INT32_MAX	Used by the map Thing spawning code to signify that the Thing's Z position is on the sector's ceiling. This is corrected to the appropriate height in P_SpawnMobj for newly spawned Objects.

SH_FIREFLOWER	0x100 (256)	Fire Flower shield flag. Note: This can be combined with any of the other shields. Use (player.powers[pw_shield] & SH_FIREFLOWER) to check if a player has this shield.
SH_FORCE	0x200 (512)	Force Shield flag. On its own this flag only gives one health point to the shield – the lower 8 bits can be used as extra health points (max extra health is 0xFF, or 255). Note: This cannot be combined with any of the values SH_JUMP to SH_PITY. Use (player.powers[pw_shield] & SH_FORCE) to check if a player has this shield.
SH_STACK	0x100 (256)	Mask for all shields that can be combined with others (only includes Fire Flower currently). Use (player.powers[pw_shield] & SH_STACK) to get all shields that can be stacked with others.
SH_NOSTACK	~SH_STACK	Inverse of SH_STACK, mask for all shields that cannot be combined with others. (player.powers[pw_shield] & SH_NOSTACK) would therefore return any of the values from SH_NONE to SH_PITY, or instead SH_FORCE plus the extra health points

Console variable flags (CV_*)

Value	Name	Description
1	CV_SAVE	The console variable's value is saved to config.cfg when changed. Currently does not really work for custom Lua-defined console variables because they are erased from config.cfg if they are not defined (i.e., if the script that defines them is not loaded) when the game is launched.

16	CV_FLOAT	The variable takes floating-point values, i.e., non-whole numbers such as 0.5 and 0.45 are accepted. These are then converted to a fixed-point integer value (e.g.: "0.5" becomes FRACUNIT/2).
32	CV_NOTINNET	The variable cannot be changed in netgames.
64	CV_MODIFIED	This flag is set when the variable is modified.
128	CV_SHOWMODIF	The console displays a message when the variable is modified.
