I've been looking for an answer, but I'm not sure this is right. I have a basic payday system where you get paid on the 28th. It activates right, but it doesn't do the math. Did I write it wrong?

Code:

    if day == 28: #Payday
        if LDeductions = True: #Late last month take 10% from pay.
            $ pay += (((baserate * PLevel) * 28) - 10%)
        else:
            $ pay += ((baserate * PLevel) * 28) #base rate (5 x PlayerLevel) x 28 days.
        ttext "After deductions I recieve [pay] gold."
        $ coins += pay
        $ pay = 0

The problem is the %. that's not 10%, that's the modulo operator which is really confusing to people starting out with programming.

What you could do is:

Code:

$ pay =  (((baserate * PLevel) * 28) )
$ deductions = pay * .1
#assuming you what a whole number
$pay = int(pay - deductions) 

That help?

Instead of adding a variable, you could just multiply by 0.9, and then convert to integer

Code:

$ pay += int(0.9*((baserate * PLevel) * 28))

and shouldn't

Code:

if LDeductions = True:

be like this?

Code:

if LDeductions == True:

Even better would be:

Code:

if LDeductions:

It's the same as Minnfae version, but more in line with python style.

Okay, I figured the out the percent, the first example works out great. I have a second problem. Every time I use this even in a call it runs twice. Giving the payday out twice. What happened?

Code:

label PayRent: #Payday and rent events.
    if day == 3:
        if coins >= rent:
            $ coins -= rent
            if LDeduction == True:
                "There, I was able to finally pay rent on time."
                $ LDeduction = False
                $ PDeduction = 0
            else:
                ttext "Room and board are always due on the 3rd of every season. Paid [rent] for rent."
                jump dayplanner
        else:
            if LDeduction == True:
                $ coins = (coins * 0.75)
                ttext "Again! I don't have rent, well here's 75 percent of what I have now I guess...I'm going to be dudcuted an additional 10 percent!"
                $ PDeduction += 0.1
            else:
                $ coins = (coins * 0.75)                
                ttext "I don't have enough for rent! I'll have to pay 75 percent of what I have now I guess..."
                $ LDeduction = True
                $ PDeduction += 0.1
    if day == 28: #Payday
        if LDeduction == True: #Late last month take 10% from pay.
            if PLevel == 0: #This is just a safeguard if you're still level 0 the first month. I hope not!
                $ pay = ((baserate * (PLevel + 1)) * day)
                $ deductions = int(pay * PDeduction)
                $ pay = int(pay - deductions)
            else:
                $ pay += (((baserate * PLevel) * day) - 10)
                $ deductions = int(pay * PDeduction)
                $ pay = int(pay - deductions)
        elif LDeduction == False:
            if PLevel == 0: #This is just a safeguard if you're still level 0 the first month. I hope not!
                $ pay += ((baserate * (PLevel + 1)) * day)
            else:
                $ pay += ((baserate * PLevel) * day) #base rate (5 x PlayerLevel) x 28 days.
        ttext "After deductions I recieve [pay] gold."
        $ coins += pay
        $ pay = 0
return

It's hard to say, since we don't know what you intended.

It looks like you're mostly incrementing pay (+=) rather than assigning it (=), so that could be the cause.

Hmm, when I switched the day == 28 and day == 3 around ti ended up working fine. Probably just a way it's stated.
