Flag behavior

The flag determines whether some variables should be updated

The flag is set upon:

• Opening the menu
• Closing the preview of a Scratch Card

The flag is cleared upon:

• Closing the menu
• Opening the preview of a Scratch Card

The flag is not set back when a Scratch Card is discarded

• Main reason the glitch exists

Updates requiring (flag == 1)

Opening [Main Menu] for the first time

equipment_list = &Weapons;
equipment_id = characters[current_character]->id_weapon;
equipment_attributes = characters[current_character]->attributes_weapon;

Highlighting an equipment from [Equipment]

equipment_list = type[submenu_index_equipment];
equipment_id = characters[current_character]->id_any;
equipment_attributes = characters[current_character]->attributes_any;

Closing [Equipment]

equipment_list = &Weapons;
equipment_id = characters[current_character]->id_weapon;
equipment_attributes = characters[current_character]->attributes_weapon;

Opening [Equipment] - [Any]

equipment_list = type[submenu_index_equipment];

Highlighting an equipment from [Equipment] - [Any]

equipment_id = equipment_list->id[equipment_index];
equipment_attributes = equipment_list->attributes[equipment_index];

Closing [Equipment] - [Any]

equipment_id = equipment_list->id[0];
equipment_attributes = equipment_list->attributes[0];

Note: these modifications are overridden as [Equipment] is then opened

Opening [Items] - [Any]

equipment_list = type[submenu_index_items];

Highlighting an equipment from [Items] - [Any]

equipment_id = equipment_list->id[equipment_index];
equipment_attributes = equipment_list->attributes[equipment_index];

Closing [Items] - [Any]

equipment_id = equipment_list->id[0];
equipment_attributes = equipment_list->attributes[0];

Opening [Scrolls] - [Any]

equipment_list = type[submenu_index_scrolls];

Note: highlighting a scroll updates other variables regardless of the flag

---

General rules

Highlighting an equipment

• equipment_index ranges from 0 to equipment_list->length - 1

Discarding an equipment

• Discarded equipments use equipment_id and equipment_attributes
• Clears entry equipment_index from the list the equipment would come from
• Crashes the game if equipment_id == NULL

---

Main applications

Transmutation from the first equipment of a list

• Open [Equipment] or [Items] - [Any_0]
• Discard a Scratch Card from [Scratch_Cards]
• Discard equipments from [Items] - [Any_1]

Transmutation from a scroll

• Discard a Scratch Card from [Scratch_Cards]
• Highlight a scroll from [Scrolls] - [Any_0]
• Discard equipments from [Items] - [Any_1]

Infinite transmutation from a scroll

• Considering [Any_1] different from either [Weapons] or [Any_0] respectively
• Open [Equipment], [Items] - [Any_0], or [Scrolls] - [Any_0]
• Discard a Scratch Card from [Scratch_Cards]
• Highlight a scroll from [Scrolls] - [Any_1]
• Discard equipments from [Items] - [Any_2]
