Yes this is possible Basilboy, if you understand that the formula is doing for you. That Riemann sum is for figuring out what the next XP level is for any given level number, from 0 to Max Level-1. Putting it in a loop will calculate every XP Boundary value when the loop is ran, this is not what you need. I think you just simply want to know the next level boundary at the time the level is increased. Here is loosely how you can use that:
Get yourself some global variables
CurrentLevel = 1
CurrentXP = 0
NextLevelAt = 75*2^(1/7) which is approx 82
Now set up an event
If CurrentXP > NextLevelAt its time to level up!
- Set CurrentLevel = CurrentLevel + 1
- Set NextLevelAt = NextLevelAt + (75*2^(CurrentLevel/7)
ORRRRRRRRRRRRRRRRRRRR!
You could just calculate out what all the level boundaries are by hand and hold them in C2 variables or array without using the formula in game.
Level 1 XP Boundary = 75*2^(1/7)
Level 2 XP Boundary = Level 1 XP Boundary + 75*2^(2/7)
Level 3 XP Boundary = Level 2 XP Boundary + 75*2^(3/7)
Level 4 XP Boundary = Level 3 XP Boundary + 75*2^(4/7)
[82, 173, 273, 384, .................]
