No, I mean you plug it like this:
package Elf;
sub named {
my $class = shift;
bless {
Name => shift;
Actions => Elf::Live::,
Has => {},
}, $class;
}
sub die {
shift->{Actions} = Elf::Dead::;
}
sub can_attack { # delegate to actions
shift->{Actions}->can_attack(@_);
}
sub enemy_of {
shift->{Actions}->enemy_of(@_);
}
package Elf::Live;
sub can_attack { ... }
sub enemy_of { ... }
package Elf::Dead;
sub can_attack { ... }
sub enemy_of { ... }
A simple change of the Actions variable by plugging in a different
"behavior container" causes a bank-switch of those behaviors to a new
motif. I forget the "gang of four" pattern for this, but it's one of those. {grin}

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).
