I'm playing around with a game concept. Here is my basic enemy.

package Enemy;
use Moos;

has wounds  => ();
has att_type => ();
has def_type => ();

sub BUILDARGS {
    my ($self, $type) = @_;

    my %monster = (
        'Rat' => { 
            wounds   => 1,
            att_type => 'light',
            def_type => 'dodge',
        },
    );
    die "Unknown monster type" unless exists $monster{$type};
    $monster{$type}{'type'} = $type;
    return $monster{$type};
}
    
1;
}

my $monster = Enemy->new('Rat');

I'm having some trouble with the design of the attack / defense traits of an enemy. I would like to have multiple attacks with some statistics of their own. Something like this:

my %attack = (
    basic_light => { type => 'light', damage => '1', defmod => { block
+ => '0', dodge => '0' } },
    basic_heavy => { type => 'heavy', damage => '2', defmod => { block
+ => '0', dodge => '10' } },
);

During the fight, I will call something like:

$a = $attacker->choose_attack();

# with the intention of 
# $a == { type => 'light', damage => '1', defmod => { block => '0', do
+dge => '0' } }

Still, I don't want to pass anything too complex to the constructor. I think that I have to keep the attack definitions within the Enemy class, and to have something to translate the attack type to a pattern.

For example: att_type => 'medium' would translate to an array of ( $attack{basic_light}, $attack{basic_heavy}), and the choose_attack() method would pick an attack from this array at random. Which would correspond to an enemy that hits heavy about 50% of the time.

How can I add it to the code in an elegant way? Should I drop the att_type and just initialize the monster with an attack pattern? I humbly seek your words of wisdom. Any advice will be welcome.
