So,
I’m trying to create a database of JSON representing barcode numbers and related information, but when I call on my globally loaded script to write to a file it ends up overwriting anything that was already in the file.
extends "res://Scripts/item_class.gd"
var inventory := []
const userData := "res://localDatabase.txt"
func get_upc_data(barcode: String) -> Dictionary:
var readData = File.new()
if not readData.file_exists(userData):
return {"Status": "File Doesn't Exist"}
readData.open(userData, File.READ)
while readData.get_position() < readData.get_len():
var data = parse_json(readData.get_line())
if data.get("Barcode") == barcode:
readData.close()
return {"Status": "Success", "Data": data}
readData.close()
return {"Status": "Not Found"}
func store_upc_data(data: Dictionary) -> void: #The function I'm having issues with
var storeData = File.new()
storeData.open(userData, File.WRITE)
storeData.seek_end() #Puts the writing cursor at the end of the file
storeData.store_line(to_json(data)) #Stores the dictionary as JSON data
storeData.close()
As an unrelated question is it possible for me to read and write to a .JSON file instead of a .txt file? Also, if you require to see the item class that I’m extending, here it is.
extends Node
class_name Item
#### CLASS VARIABLES ####
var item := {
"Barcode": "00000000",
"Metadata": {
"Name": "Name",
"Description": "A short description of the item.",
"Quantity": 1,
"Product Category": "General",
"Product Units": "ounces",
}
}
#### SET DICTIONARY VARIABLES ####
func set_item(nBarcode: String, nName: String, nDescription: String, nQuantity: int, nCategory: String, nUnits: String):
var meta := {
"Name": nName,
"Description": nDescription,
"Quantity": nQuantity,
"Product Category": nCategory,
"Product Units": nUnits,
}
if item.has("Barcode") and item.has("Metadata"):
item["Barcode"] = nBarcode
item["Metadata"] = meta
func set_item_with_object(nItem: Item) -> void:
item = nItem.item
func set_item_with_dict(nData: Dictionary) -> void:
var nMeta = nData["Data"]["Metadata"]
item["Barcode"] = nData["Data"]["Barcode"]
item["Metadata"]["Name"] = nMeta.get("Name", "Name not found")
item["Metadata"]["Description"] = nMeta.get("Description", "No description found")
item["Metadata"]["Quantity"] = nMeta.get("Quantity", -1)
item["Metadata"]["Product Category"] = nMeta.get("Product Category", "No category found")
item["Metadata"]["Product Units"] = nMeta.get("Product Units", "No unit found")
### GET WHOLE ITEM ###
func get_item() -> Dictionary:
return item
### SETTERS ###
func set_name(nName: String) -> void:
item["Metadata"]["Name"] = nName
func set_description(nDescript: String) -> void:
item["Metadata"]["Description"] = nDescript
func set_quantity(nQuant: int) -> void:
item["Metadata"]["Quantity"] = nQuant
func set_category(nCategory: String) -> void:
item["Metadata"]["Product Category"] = nCategory
func set_units(nUnits: String) -> void:
item["Metadata"]["Product Units"] = nUnits
func set_barcode(nBarcode: String) -> void:
item["Barcode"] = nBarcode
### GETTERS ###
func get_name() -> String:
return item["Metadata"]["Name"]
func get_description() -> String:
return item["Metadata"]["Description"]
func get_quantity() -> int:
return item["Metadata"]["Quantity"]
func get_category() -> String:

func get_units() -> String:

Thank you for any help you may have!
