This tutorial demonstrates how to set up the Save and Load module to save player data, and reset it (by deleting the save file).
Data loading is automatic -- the system will automatically attempt to load the last saved data, so nothing manual has to be done!
Note: The Tower Defense Demo Game utilizes only a single save file. The concepts here remain the same for a project with multiple save files, but check out the Party Based RPG Demo Game to see how to use the Save and Load module with multiple save files.
