Calculating Level

[Waizujin]

I am creating a game with a plethora of skills such as mining, woodcutting, fishing, etc.

I need to calculate the users level based off of a formula. I am using the below code, and I would like to know if you think that it is efficent and will it give me the proper level?

Code: [Select]

function grabLevel($exp) {
for($level = 1; (pow($level, 3) * 20) < $exp; $level++) {
return $level;
}
}

The experience formula is Level^3 * 20

So level 5 would require 2,500 Experience in that skill. All skills use the same level formula.

better to have a formula than a cycle

Code: [Select]

<?php
function getLevel( $exp ) {
    return floor(pow(($exp/20), 1/3));
}edit: added floor()

So that will give the same result?

well you can try it for yourself

Code: [Select]

<?php
echo getLevel(0)."<br>\n";
echo getLevel(1)."<br>\n";
echo getLevel(25)."<br>\n";
echo getLevel(79)."<br>\n";
echo getLevel(1000)."<br>\n";
echo getLevel(2499)."<br>\n";
echo getLevel(2500)."<br>\n";
echo getLevel(2501)."<br>\n";
// ...
** in other words **

it should, it should be exactly reversed formula as you provided

That's amazing! Thanks! I suck at math so I would have never figured it out. XD
