I am making a game where one object needs to get the rotation of another. I want to have one object (a banana) put its rotation into the variable and have the 2nd object access it and set its own rotation to match. ex:(pseudo code) Banana: Var = getRotation() 2nd object: setRotation(Var) I think I could do this by defining the variable in a common super class, but I am not sure how this would work.

The rotation is already saved in a field provided by the Actor class and its value can be retrieved by the 'getRotation' method. You just need a reference to the Banana object itself so you can get the rotation of that specific object:

// with a defined variable
Actor banana =  < assignment of a reference to the banana >;
// in code
int bananaRotation = banana.getRotation();

Thank you for the quick reply. Would this code be inside bananas's code or the 2nd object that is set to banana's rotation?

Also, how would I assign a reference to banana? I have seen it before but am not clear on how a reference works. Thanks!

It depends on whether you only have one banana in the world or more -- and then how would you want to determine which one, if more.

Thank you again for the help, danpost. There will only be one banana on the world, the (unfinished) game is on my profile page. If you don't have the time to look at it, no problem. PS: yes I know banana is spelled wrong and no, no one thinks brooklynnetswn is cool.
