Is this a good way to implement a Battleship game?

wickedxter has asked for the wisdom of the Perl Monks concerning the following question:

Is this a good way of going by this?

The code snipplet is part of a game for calulating battles, it goes ship by ship each searching (randomly) targets of the other side and caluating if the ship has more then one weapon. If this doesnt explain enough just ask and i'll go through and break the code down.

It's kinda long.

## Battleship
if($d_batt){
for my $x (1..$d_batt){
    my $rand_ss = int rand(4);
    if($rand_ss eq 1 && $a_crv ne 0){
        
        #weak target
        my $weak = int rand 2;
        if($weak eq 0 || $weak eq 2){
        for (1..16){
            my $w_s = int rand(100);
            next if $w_s gt $config->{percent_hit}{batt};
            my $y = int rand $a_crv;
            $y++ if $y eq 0;
            push(@{$data->{shots}{defender}},"$y|crv|batt");
            $data->fleet_d("defender","attacker");
        }
        }else {

how large is your "move space", that means how many possible moves are there? normally, you give moves a score and choose then the best one. if the move spaces is small enough, you can evaluate all. then you can choose a optimization strategy, e.g. choose the n best moves and evaluate all (or good) opponents moves. and you should write `if ($i == 1)` [download] for numbers. `if ($i eq '1')` [download] for strings.

Is this a good way It all depends: are you trying to optimise for speed or low memory consumption or a clean and expandable design or ... ? Strange as it may be some people even go for a maximum of obfuscation! I'm afraid that without some design goals no-one can tell you if you succeeded in reaching that goal.

It has already been pointed out that using `eq` to test the equality of numbers is wasteful affected. I should also add that using `gt` to compare numbers will not do what you probably intended because `3 gt 20` is true.	[reply] [d/l] [select]
