HUD Help

[Marcel_Makkink]

I expanded my HUD once again, however the last thing I would like isn't working, really.
Because I'm like trying for the past 10 hours how to do something like this :

@percent = @now_exp / @next_exp * 100.00

So that it shows the % of Exp. that is already gotten.
  For understanding :
  - You need 20 Exp. to get to Level 2.
  - You defeat a monster and get 2 Exp.
  - You now have 10.00% (With the decimals. :cool

Spoiler: My HUD

SWITCHC = 43 #change to your switch, don't put in any leading zeros!

return @exp_list[@level+1] > 0 ? @exp_list[@level+1] - @exp_list[@level] : 0

Thanks if anyone is willing to do this for me. I'm tired and sick of this. ???
Btw; If you look in the script you'll see I #'ed the pictures I use.

The instance variable @level in Game_Actor stores the actor's initial level, not its current level, which can be obtained with Game_Actor#level.  That's because the actor's level is calculated from its current experience.  Therefore the problem can be fixed by replacing "@level" with "self.level".  Note that the expPercent method below, also of Game_Actor, retrieves the EXP percentage as you request.  Replace the code at the top (except the switch constant) with:

class Game_Actor
#--------------------------------------------------------------------------
# * Get the current EXP
#--------------------------------------------------------------------------
def now_exp
return @exp - @exp_list[self.level]
end
#--------------------------------------------------------------------------
# * Get the next level's EXP
#--------------------------------------------------------------------------
def next_exp
return @exp_list[self.level+1] > 0 ? @exp_list[self.level+1] - @exp_list[self.level] : 0
end
def expPercent
  percent = self.now_exp / self.next_exp * 100.00
  return sprintf("%.2f%%",percent)
end
end

EDIT4
I've been like trying to get this right for 22 hours total.

The problem was the calculating method I guess, I changed:

procent = self.now_exp / self.next_exp * 100.00

Into :

procent = 100.00 / self.next_exp * self.now_exp

This has been resolved, thanks to :
- poccil. <Teaching>
- My dad. <Reminding me that there's more than 1 method to calculate percentage.>
- Myself. <Coding> ;D

=================================================================

Thanks for explaining that to me poccil. :cool:
I did what you said however, the exp. percentage remains at 0.00%.

EDIT1 :

I just tried it in a new project, still no luck, same result.

EDIT2 :

The percent still doesn't work however, I remade the third def of your code into this :

def percent
  if self.next_exp == 0
  procent = 0.00
 return sprintf("%.2f%%", procent)
 else
  procent = self.now_exp / self.next_exp * 100.00
 return sprintf("%.2f%%", procent)
end
end
end

Is that correct? (Because there was an error when the actor was at the max. level.)
