I am trying to make progress offline but I don’t know how. Can anyone help me, please?
Wrong forum section to post this in assuming you mean in-game progress, better fit is Scripting section.
One idea is to store the time the game closed (or simply do it every few seconds in case something goes wrong and it doesn’t save on exit)
Then when the game is launched again, pick up the time you saved, and the current time, then calculate how much time passed since then and do the progress based on that time (for example resources +5000, crafting finished, etc)
