Modding:Constants

Constants and Enumerations are common in any game and DoomRL is no exception. Internally, as most programmers are aware, these are integers. But to modders they are all important magic values, looked up here.

Engine Enums

ItemType

Every item has a type that determines how the engine treats it.

ITEMTYPE_PACK

ITEMTYPE_POWER

BodyTarget

Sources of damage must specify a body target to determine which sources of armor are used. Inherent armor bonuses always apply.

TBodyTarget
TARGET_INTERNAL	Protection from boots and armor will be ignored.
TARGET_TORSO	Protection from armor counts but protection from boots does not.
TARGET_FEET	Protection from boots counts but protection from armor does not.

EqSlot

It is preferred to use the (equivalent) slot constants.

TEqSlot

EFTORSO

EFWEAPON

EFBOOTS

EFWEAPON2

StatusEffect

Affects specify one of these status effects that will apply a color scheme to all the tiles on the HUD.

TStatusEffect

STATUSNORMAL

STATUSINVERT

STATUSRED

STATUSGREEN

DamageType

Sources of damage usually specify a damage type that determines how the damage regards protection, resistances, gibbing, and other things. For details on the differences between the damage types, look here.

ExplosionFlag

TExplosionFlag
EFSELFHALF	Deals half damage to the active being.
EFSELFKNOCKBACK	Gives extra knockback to the active being.
EFSELFSAFE	Deals no damage to the active being.
EFAFTERBLINK	Blinks the screen after the explosion finishes.
EFCHAIN	Causes secondary explosions (as the BFG 9000).
EFHALFKNOCK	Causes half the usual knockback.
EFNOKNOCK	Doesn't cause knockback.
EFRANDOMCONTENT	Transmutes some cells in the explosion to the explosion's content cell; the rules is to transmute when damage is greater than 20.

LightFlag

TLightFlag
LFEXPLORED	This flag is set for explored cells. It can be modified to create computer map-like effects or Angel of Darkness-like effects.
LFVISIBLE	This flag is set for cells in the player's current LOS. This flag is automatically recalculated on every player action. It may be useful to manually modify this flag if LOS needs to be updated more often.
LFLIGHTED	This flag is always set on the same cells as LFVISIBLE; both flags must be set for a cell to be visible.
LFDAMAGE	This is a book-keeping flag for shotgun area-of-effect. Cells are set with this flag if they are calculated as in the shotgun blast but haven't yet been processed.
LFFRESH	This is a book-keeping flag for explosions. New corpses are set with this flag to keep them from being immediately destroyed. This flag can be set to make any cell indestructible, but it may be cleared by the engine.
LFNOSPAWN	Cells with this flag are counted as non-empty by the EF_NOSPAWN empty flag.

Colors

Usually, it is possible to specify a foreground color and a background color. Since DoomRL uses 4 bit color, the lowest 4 bits determine the foreground color, and the next 4 bits determine the background color (zero is black). Occasionally, one of these may conflict with one of the special color constants.

Also, note that the exact color the end-user sees may depend on his system settings.

For the basic 16 colors, the valkyrie string coloring escape is noted.
