Formula for experience

[mario_sunny]

Hi, I was wondering just out of curiousity if anyone had the formula to determine how much exp you would need for the next level. For example, to get level 2 you need 83 exp, level 3 176 exp(I think).

its on tip.it, on the left side i belive it says xp table? something along those lines, try that

 

 

 

 

 

 

 

edit:its under tools on the left side

[Vulxai]

just check the xp table

[mario_sunny]

I know about the exp table, I just want to know the formula.

[Vulxai]

there really isn't a formula

Try this site:

That site gives formula but I think you can rewrite it to something 'easier'.

 

 

 

 

 

 

 

It should be an exponential function (don't know if you call it this way in english tough) like:

 

 

 

 

 

 

 

Xp = B* X^Y

 

 

 

 

 

 

 

If you got a good grpahic calculator, like a TI-84, you can put all of the numbers (level and xp) in a list and then enter a certain command (for TI-84: RegExp if I remember correctly) and it will give you the exact formula 8-)

Here's the code for different programing languages:

 

 

 

Visual Basic:

 

 

 

Public Function experience(ByVal lvl As Integer)

 

 

 

Dim a As Long

 

 

 

Dim x As Integer

 

 

 

For x = 1 To lvl

 

 

 

a = a + Int(x + 300 * (2 ^ (x / 7)))

 

 

 

Next x

 

 

 

experience = roundDown(a / 4)

 

 

 

End Function

 

 

 

 

 

 

 

PHP:

 

 

 

<?php

 

 

 

 

 

 

 

function experience($L) {

 

 

 

$a=0;

 

 

 

for($x=1; $x<$L; $x++) {

 

 

 

$a += floor($x+300*pow(2, ($x/7)));

 

 

 

}

 

 

 

return floor($a/4);

 

 

 

}

 

 

 

 

 

 

 

for($L=1;$L<100;$L++) {

 

 

 

echo 'Level '.$L.': '.experience($L).'

 

';

 

 

 

}

 

 

 

?>

 

 

 

 

 

 

 

Microsoft Excel:

 

 

 

Cell A1: 1

 

 

 

Cell B1 formula: =ROUND.DOWN(A1+300*POWER(2;A1/7);0)/4

 

 

 

Cell A2: 2

 

 

 

Cell B2 formula: =B1+ROUND.DOWN(A2+300*POWER(2;A2/7);0)/4

 

 

 

 

 

 

 

Fill the rest of the first column with numbers 3, 4, ...

 

 

 

Copy B2 field formula down.

 

 

 

 

 

 

 

Javascript:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Python:

 

 

 

points = 0

 

 

 

for level in range(1,100):

 

 

 

diff = int(level + 300 * math.pow(2, float(level)/7) )

 

 

 

points += diff

 

 

 

str = "Level %d = %d" % (level + 1, points / 4)

 

 

 

print str

 

 

 

 

 

 

 

Hope this helps

I am not a man of math, could you please explain what the hell all those numbers mean? I don't understand why you can't just give me the formula and all the "x ="'s.

[pulli23]

Wait, you want a formula, but you don't want any x's and = signs???

 

 

 

 

 

 

 

btw it's I believe not a very easy function... maybe it's a recursive function, but with Origin 7.5 (a profesional program I need to use at university) when I try to draw a curve through the values, I get the best results with an power function (y = a*b^(cx + d) + e) - however the result still has a pretty high standard deviation, while it should be perfect (S should be 0).

 

 

 

 

 

 

 

I also tried some simple linearization tricks, but they all don't work..

 

 

 

 

 

 

 

So my conclusion is that it's a recursive function - and since I'm not a math student (physics) I don't really know how to get such a function... sorry

It's not that simple; there's no "easy" forumla.

I never said I didn't want that, in fact I said I did want that. :|

 

 

 

 

 

 

 

Nevermind the formula seems to be very confusing. I'm not curious anymore...
