( #3333=superdoc: print w/replies, xml ) Need Help??
So I'm determined to do it the hard way, so that at the end (if there is an end),

Doing it the hard way is a time-honored tradition :) I just suggested you check out how the others work so that you can steal good ideas & interfaces.

is the long string in your penultimate line a single scalar for all purposes?

You mean $character{'Bob the Fighter'}->{'Attributes'}->{'Str'}? Yes, because in the end it is just a value stored in a hash, and only scalars can be thus stored. By dereferencing part of that mess, you can get a hash. For example, %{ $character{'Bob the Fighter'}->{'Attributes'} } is the Attributes hash. (The scalar value $characters{'Bob the Fighter'}->{'Attributes'} is a reference to a hash. the %{ } dereferences the reference.

Could I include lists in that hash by reference?

Absolutely. A reference to anything is a scalar, and a hash can store a scalar. An anonymous list can be created by [], or you can use the backslash reference. So:

$characters{'Bob the Fighter'}->{'Feats'}= [ 'Strong Spit', 'Perl Guru +']; # or @feats = ('Strong Spit', 'Perl Guru'); $characters{'Bob the Fighter'}->{'Feats'} = \@feats;
both work just fine. You can then access them like:
$characters{'Bob the Fighter'}->{'Feats'}->[1]; #is equal to 'Perl Guru'
Remember that although we're using a hash as our "base" variable here, we could use any other data type that is appropriate. A list could work:
as could a scalar:
$characters->{'Bob the Fighter'}->{'Attributes'}->{'Str'};
(Assuming you had stored the data in that fashion.)

If, for example, $character{'Bob'}->{'Class'} holds 'Ftr', and $class{'Ftr'}->{'Base Attack'} holds 'Good' (to indicate that fighters have Good attack bonuses, which are generated by a short procedure in the combat module), what would be the code to retrieve Bob's Base Attack type?

Well, $class{$character{'Bob'}->{'class'}}->{'Base Attack'} would be equal to $class{'Ftr'->{'Base Attack'} (actually, it would _BE_ the same, since all that happens is $character{'Bob'}->{'Class'} resolves to 'Ftr') However, this assumes that Bob's class will ALWAYS have an entry in %class.

Storing feats, spells, etc. as booleans is not efficient, IMHO. I want to be able to brew a new feat and not have to go and set the bit in all the PCs.)

Just so you know, Perl handles non-existant hash keys quite nicely, and it's quite common to see code that would be like:

if($char{Bob}->{Feats}->{'Good With Pointy Objects'}){ Kill_Bad_Guy(); } else { Die_Hideous_Death(); }
If Bob doesn't have that feat, you don't have to set it to 0, you simply don't set it to a true value, and it will evaluate False. (Well, undefined, which in turn is false)

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
