[HALF SOLVED] How do I make an in-game store?

Just do that right before the transition to the next scene.

Thanks it works the way i want it to. Now i have to create the shop itself and take money away.

You can have whatever behavior handles the scene change also handle saving the values together.

So, right before the "change scene" block for "when actor enters region", add one that does your "set Money to (Money + MoneyFoundThisLevel)"

Edit: Whoops, I was on the last page. Glad that it's working, haha!

Yeah i've looked on the wrong page before. Thanks anyway.
