Saving and loading to and from external file?

Hello folks,

I know this should be possible and relatively easy, but I can't wrap my old brain around this and have not been able to find a complete answer here.

For a webbased educational app I am developing I am looking for a way to save the state to an external file (probably JSON) and load it later. This could be on a different system at a school so it has to be an external file, not local storage.

So far I think I managed to save the state to a JSON file (saving the game, on save complete invoke download of the string SaveStateJSON). But I can't work out how to load the state from this file again. I know there is a "load game from JSON" action, but I don't know how to get it to read the external file.

Any help would be much appreciated!

Use the "File system" or "File chooser" plugins to load up local files.

Thanks! When the file is loaded, how do I access the JSON string within to load the state?

Got it working, thanks! I had to use to file chooser to load it and the AJAX object to get the string.
