Function to retrieve isOpen

[timonsku]

I updated my local version and ran into the issue that isOpen is now private. So I added a function to retrieve it.

Cool - I think I changed it as setup returns a bool you can track yourself but I can see it being useful to get it from the class.

I'll go ahead and merge it but eventually change isOpen to didOpen make getIsOpen() isOpen()

Yes that sounds good! I didnt want to change the variable name just now.

Having setup return it is helpful aswell. I use it when I close the player on user input and need to know when it actually closed and I can re-use the player object. In that case getting the bool is usefull.
