Data Save
DataSave plugin offers an easy and efficient way to save and load game data, perfect for indie game developers. By using Gameplay Tags and DataAssets, this plugin allows you to define and organize your save data with ease. The plugin provides straightforward Blueprint functions for saving and loading data, making it simple to manage game states, player settings, and other crucial information. DataSave plugin seamlessly integrates with other Indie GameKit plugins, providing a reliable solution for all your data management needs.
Setup
Add Gameplay Tags to identify save files. Each save file requires 1 Gameplay Tag. Use the IndieGameKit.DataSave.* space.
Create a new save file. If you already have a save file, you can use it, just skip this step.
Create any number of variables to save.
Create a new Data Asset that will manage the connection between the save files and Gameplay Tags.
Pick DataSaveDataAsset as class for Data Asset instance.
Go to Project Settings > Plugins > IGK Data Save and specify the previously created Data Asset
Usage
Data Save Subsystem
Saving to any Blueprint
Retrieving a save file in any Blueprint
This custom node determines the type of the output pin at compile time.
Why use this method instead of directly using the subsystem?
This approach allows us to determine the output pin type during compilation, avoiding extra casting operations at runtime. It also simplifies the system’s usage, as you don’t need to worry about the exact save class when calling a function.
Access to information entered during the setup phase
Hint
During game development, it’s common to need to rename or delete variables within a save file. Additionally, rebalancing the game’s economy might require resetting all player progress and starting anew. To manage these situations, a Version variable within the DataAsset is used. By incrementing this variable, you ensure the creation of a new save file.
Advanced
To use a value that is only known at game runtime, you can either use a Blueprint Function Library or use a custom node with a connection. In this case, you’ll need to cast the variable to the correct type before using it.
