Hello!
I am a new person in this matter
I am trying to integrate two inventory systems into one - since in each of them there is not what is in the other

So my goal is a displayed inventory list with the ability to put on and take off things from the character, such as weapons, armor and other things with a change in the character’s characteristics

Here is my code

Code: Select all

сharacter.rpy
init python: 

    class Player:
        def __init__(self, hp, mp, atk, defense, mdef,level=1):
            self.hp = hp
            self.mp = mp
            self.max_hp = hp
            self.max_mp = mp
            self.atk = atk
            self.defense =defense
            self.mdef =mdef
            self.level = level
            self.weapon = None
            self.armor = {"head": None, "chest": None, "acc" : None,"shield":None}


        def addHP(self,amount):
            self.hp += amount
            if self.hp > self.max_hp:
                self.hp = self.max_hp



        def addMP(self,amount):
            self.mp += amount
            if self.mp > self.max_mp:
                self.mp = self.max_mp

        def equip_weapon(self,weapon):
            if self.weapon != None:
                self.unequip_weapon()

            self.weapon = weapon
            self.atk += weapon.atk

        def unequip_weapon(self):
            if self.weapon != None:
                self.atk -= self.weapon.atk
                self.weapon = None


        def equip_armor(self,armor, slot):
            if self.armor[slot] != None:
                self.unequip_armor(slot)
            self.armor[slot] = armor
            self.defense += armor.defense
            self.mdef += armor.mdef


        def unequip_armor(self,slot):
            if self.armor[slot] != None:
                self.defense -= self.armor[slot].defense
                self.mdef -= self.armor[slot].mdef
                self.armor[slot] = None

In general and in general, the system works fine but there is one problem - namely, equip does not work through the button
received error
While running game code:
unbound method equip_weapon () must be called with Player instance as first argument (got revertable list instance instead

Or if on list inventory screen. rpy on line 122 I change to

Code: Select all

textbutton "Equip"  action Function( selected_item.equip,pc)

which is typical for the first system

I get an error

RevertableList has no attribute equip

In general, I tried different options to declare this function - but they all lead to an error, but the code
in screept.rpy

Code: Select all

$ pc. equip_weapon (sword)

puts a sword on the player

As far as I can judge, the problem is that somehow the image of the items and the inventory is displayed differently and does not have the form for which the teams from the first inventory option work
Although maybe I'm wrong

I would be grateful for a hint on how to avoid this.

If I change the cod of the button to

Code: Select all

 textbutton "Equip"  action Function( Weapon.equip,selected_item,pc)

I get an error
unbound method equip() must be called with Weapon instance as first argument ( got revertable List instace instead)

as far as I understand the problem is that the click handler does not have the correct information about the item in the inventory
How can this be fixed?
