Is there any way to store persistent data?

• I'm playing a game
• I save the game (I plan on using the game.onsave() event to know when to store the data)
• I close Factorio
• Open it back up later
• Load the save game
• The variable that I stored is still there for access

Anythin in the glob table is "automagically" saved and loaded for you. It works for plain data (integers, strings, tables, etc.) as well as for factorio objects (lua entity, lua technology, etc.). I would avoid storing functions in there.

That's useful. I've been storing all my functions there!

In theory it should work for some simple functions. However it will fail for things like closures and generated functions. You can actually check the file called script.dat in the save directory. It contains the serialized state of the script. There are some binary data now and there but most of it should be readable and "lua-code" like.

Just looked at it. Doesn't look very friendly!

May I ask what advantages you expect when you store your functions in the glob table?

I had no clue what to expect, I just thought that was how you're supposed to do it...
