NAME

NetHack::Monster::Spoiler - information on a type of monster

SYNOPSIS

    use NetHack::Monster::Spoiler;

    my $s = NetHack::Monster::Spoiler->lookup(glyph => 'A', color => 'magenta');

    $s->is_spellcaster;          # returns 'wizard'
    $s->name                     # 'Archon'
    $s->never_leaves_corpse      # 1
    $s->ignores_elbereth         # 1
    $s->resists('petrification') # 0

DESCRIPTION

NetHack::Monster::Spoiler is a machine-readable database of information on the various monsters that inhabit the NetHack universe. It is a sort of metaclass of monsters; an instance of NetHack::Monster::Spoiler is associated with each type of monster, so there is one for Archons, one for black puddings, et cetera. The lookup class method allows one to find the correct instance for an observed monster, from which general information can be obtained using accessors.

lookup %ARGS

lookup is used to find instances of NetHack::Monster::Spoiler. It takes an optional named argument for each accessor, and returns only those monsters that match the fields. As a special exception, ANSI color numbers are automatically translated into the correct NetHack colors. Note that there is no munging for name, so in general directly using the return from farlook will do the wrong thing.

Returns all matches in list context; in scalar context it returns an unambiguous result, or undef on failure or ambiguity.

PRIMITIVE ACCESSORS

The following primitive accessors are availiable. Each of them corresponds to one field in the NetHack monster structure, with three exceptions: all breathless monsters get amphibious for free, mimics do not cling to the ceiling, and dwarves do not eat rock.

The return values of resist is a hashref which maps a truth value to each resistance the monster possesses The return value of attacks is an arrayref of hashrefs which describe each of the monster's attack(s) in terms of mode, type, and damage.

numeric_size :: Int

numeric_size returns a number with the correct ordering properties for the monster's size if called as a method, or translates strings into the same set of numbers if called as a function. The numbers used are the same as NetHack's MZ_XXX defines.

Returns true if the monster is one of the three Riders of the Astral Plane^W^WApocalypse.

has_attack MODE

Return true if the monster has an attack of the specified mode or type.

is_spellcaster

Return undef if the monster is not a spellcaster. Otherwise return the type of magic used.

is_flaming

Return true if the monster is already on fire and cannot be ignited further.
