Level Multiplier?

Questions & Answers
1

So I just finished my first Level system (which I did all on my own, very happy!) and my only problem is how the experience is multiplied every level.

Currently my system is very simple.

CurrentLevel * 15.

My problem is that when I look at games like WoW, Runescape, LeagueOfLegends, Maplestory…They all seem to have random numbers. Is it random? or do they have a complicated way of doing it?

I found those functions for a very old MMO level points system (between 0 and 200). If you can figure out the name of the game, I shall give you my eternal respect, and a friendly yet manly pat on the shoulder.

/* Recursive call to calculate Pi = Pi-1 + tx
with p1 = 10 to stop recursive call */
private int coefp( int x )
{
	return 	( x == 1 	? 10 	: coefp(x-1) + 
			( x > 192 	? 4096 	: 		
			( x > 182 	? 1024 	: 		
			( x > 162 	? 256 	: 		
			( x > 142 	? 64 	: 		
			( x > 122 	? 16 	: 		
			( x > 82 	? 4 	: 		
			( x > 42 	? 1 	: 0 ) ) ) ) ) ) ) );
}


/* Calculate the sum and call recursive function to
calculate Pi */
private int coef( int x )
{
	int n = 0;
	for( int i = 1; i < x; ++i ) n += coefp(i);
	return 1000 + n;
}

/* Calculate the total XP */
private long GetXpByLevel( int level )
{
	return (long)(coef(level - 1)*Mathf.Pow(level - 1, 2.5f));
}
