Ren'Py Manage items in a list (Array)

[RichyCapy]

Hello

I’m trying to create a delivery inventory system, in which the user when he buys something online, it takes certain amount of days to deliver

This is the class of my inventory:

init python:
    class Item:
            def __init__(self, name, namees, picture, maxallowed, daysittakes, dayspassed, cost):
                self.name = name
                self.namees = namees
                self.picture = picture
                self.maxallowed = maxallowed
                self.daysittakes = daysittakes
                self.dayspassed = dayspassed
                self.cost = cost

            def passday(self, amount=1):
                self.passday+= amount
                if self.passday> daysittakes:
                    self.passday= daysittakes

At the end of each day, I would like to see which products are on their way, and place the once arrived on another list, or add another day to the once still to arrive, so I do this:

$ poolsupply = Item("Pool Supply", "Artículos de limpieza", "quimicos.png", 1, 5, 0, 150)

$ productssent.append(poolsupply)

$ countproductssent = len(productssent)
    if countproductssent > 0:
        for product in productssent:
            if product.daysittakes = product.dayspassed:
                $ productsdelivered.append(product)
                $ productssent.remove(product)
            else:
                $  product.passday()

But Im getting this error:

I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.


File "game/historias.rpy", line 3221: expected statement.
    for product in productssent:
                ^

Thanks a lot

init python:
    class Item:
            def __init__(self, name, namees, picture, maxallowed, daysittakes, dayspassed, cost):
                self.name = name
                self.namees = namees
                self.picture = picture
                self.maxallowed = maxallowed
                self.daysittakes = daysittakes
                self.dayspassed = dayspassed
                self.cost = cost

            def passday(self, amount=1):
                self.passday+= amount
                if self.passday> daysittakes:
                    self.passday= daysittakes

Why so complicated ?

init python:
    class Item:
#            def __init__(self, name, namees, picture, maxallowed, daysittakes, dayspassed, cost):
            def __init__(self, name, namees, picture, maxallowed, daysittakes, cost):
                self.name = name
                self.namees = namees
                self.picture = picture
                self.maxallowed = maxallowed
# You don't need this.
# If you want to consider that there's already few days passed,
# just provide the right value in /daysittakes/.
#                self.dayspassed = dayspassed
                self.daysittakes = daysittakes
                self.cost = cost

            def passday(self, amount=1):
                # X days have passed, so there's X days less before the delivery.
                self.daysittakes -= amount
                # Ensure that it will not be negative for it to have a /null/-like value (see bellow)
                # Obviously, when /daysittakes/ reach 0, the delivery happened.
                if self.daysittakes < 0:
                    self.daysittakes = 0

File "game/historias.rpy", line 3221: expected statement.
    for product in productssent:
                ^

As the error say, for isn't a valid statement for Ren'py language.

Therefore, if you want a for loop, what is the best approach here, you need to use Python, either in a Python block or a function. Since you initially put the code into a label, I'll go for the first approach:

label whatever:
    [...]
    python:
        # If the list is empty, the loop will just not be proceeded.
        for product in productssent:
            # Effect of the modification made above :
            # If at least one more day before delivery, pass a day
            if product.daysittakes:
                product.passday()
            # Else (if the value is /null/) deliver
           else:
                productsdelivered.append(product)
                productssent.remove(product)
