Saving and loading Inventool data with ESave.

The code below is how you can save and load Inventool's data with ESave. ESave is my own save system—it's entirely free, and it's been tested with Inventool. ESave is not a requirement; you can use the save system of your choice. However, the example below will only work with ESave.

The example scripts automatically save on exiting Play mode and load on entering it. For real use, you’ll need to call the Save and Load methods whenever you actually want to persist or retrieve data.

The example scripts below save and load the player's inventory, equipment, recipe catalog, and stats.
