How can I save position of sprite in webstorage, is it possible? So it's in the same place when user comes back to the game, until he or she movies it again.[/QUOTE]
You have to set 2 keys: "PlayerX" and "PlayerY" for exemple, in the local storage, set to the player X and Y respectively
then when you load the game (conditions of your choice, a button maybe), you begin the layout, and at the start, you set the X of the player equal to int(WebStorage.LocalValue("PlayerX")), and for the Y, the same but with the Y
the manual should help you too:Webstorage
And that is why you shall respect the bug reports guidelines, not only giving a capx is making the bug reproductible in one click in a situation they can work with (less time wasted trying to reproduce vague instructions) but also it helps filtering false positives.
Game design is all about decomposing the core of your game so it becomes simple instructions.
