how to make a game store, I could buy only once

I make shop at game,but i don't know hot to make that I could buy only once

There are a lot of ways to go about that. One way, you could add a "Purchased" boolean variable to each item in the store (assuming they're done with Sprites).

Then use a boolean check before user is allowed to purchase the item.

Make boolean for every sprite,and to do that they are were all true?

or what?

Whenever you add an instance variable, there's a default.

The default for boolean is false, but you can change it to true.

Then you can either hide the items or stop the buying process if they're purchased.

i try to make like you say,but nothing has changed
