I'm trying to come up with a way for players to fire their weapons and only hit for a certain percentage. For example, one gun can only hit 70% of the time while another only hits 34% of the time.
So far all I could come up with is weighted arrays.
Attempt 1:
private function weighted_random(&$weight)
{
$weights = array(($weight/100), (100-$weight)/100);
$r = mt_rand(1,1000);
$offset = 0;
foreach($weights as $k => $w)
{
$offset += $w*1000;
if($r <= $offset)
return $k;
}
}
Attempt 2:
private function weapon_fired(&$weight)
{
$hit = array();
for($i = 0; $i < $weight; $i++)
$hit[] = true;
for($i = $weight; $i < 100; $i++)
$hit[] = false;
shuffle($hit);
return $hit[mt_rand(0,100)];
}
It doesn't seem that the players are hitting the correct percentages but I'm not really sure why.
Any ideas or suggestions? Is anything glaringly wrong with these?
Thanks
