Overview

This system allows for easy and quick save/load of games. Creating and implementing a save system can be tedious and time consuming, which is why I build a system that simplifies that concept and that can be used by others as well.

The SaveSystem, upon saving, creates a new directory called save_folder inside the User folder. It then stores the file inside the save_folder, where it can be retrieved from later at another point inside your project. Inside this save file you can store different types of data, like: abilities, player location, and game events. These types of data can then be retrieved and assigned respectively upon starting the game. If a file with the same name already exists, the information inside it will automatically be overwritten with the new data.

It is also possible to create/load different save files, but managing them might be a bit tricky.

Instructions

Saving

To create a save file with the SaveSystem, either create a Save Point that your Player can interact with or a script that registers certain button inputs. Once that is done, we first need to preload the SaveSystem and create a variable that holds the instance of our system.

const SaveManager = preload("res://globals/manager/save_manager.gd")
var save_manager : SaveManager

func _get_save_game() -> void:
    save_manager = SaveManager.new()

After that, I recommend creating a different function wherein you post all the data you want to save.

const SaveManager = preload("res://globals/manager/save_manager.gd")
var save_manager : SaveManager

func _get_save_game() -> void:
    save_manager = SaveManager.new()

func save_game() -> void:
    save_manager.set_value("abilities", player.abilities)
    save_manager.set_value("player_location", player.global_position)
    save_manager.set_save_game(save_path)

You can then call this function whenever you want to save your game.

Loading

To load a save file with the SaveSystem, similar to when you create a save file with the SaveSystem, you need to create an instance of the SaveSystem class. After that is done, we need to fetch the save file from the save_file folder. For clarity sake, I recommend making an unique function and assign the fetched save file to the save_file variable you just created.

const SaveManager = preload("res://globals/manager/save_manager.gd")
var save_manager : SaveManager

func _get_save_game() -> void:
    save_manager = SaveManager.new()

    var save_file = save_manager.get_save_file(save_path)

When the fetching is done, you can assign the data to objects inside your game.

const SaveManager = preload("res://globals/manager/save_manager.gd")
var save_manager : SaveManager

func _get_save_game() -> void:
    save_manager = SaveManager.new()

    var save_file = save_manager.get_save_file(save_path)
    if save_file == true:
        save_manager.get_save_game(save_path)
        # Assign loaded values.
        player.abilities.assign(save_manager.get_value("abilities"))
        player.location.assign(save_manager.get_value("player_location"))
    else:
        save_manager.set_save_data()
