I have a problem during developimg a simple game, so I visit here.
of course, my problem is no matter with farseer engine.
It is only regarding to XNA 4.0.
But the reason that I visit to fix it here is that I have always fixed my problems in developing my game.
Then from now on, I will explain about my problem.
My game has many levels.
But every levels has its own contents(images and fonts and sounds . . .).
I need to remove the contents in the level everytime one level finish.
ContentManager has the method called "Unload".
however, the method removes all contents in the whole game.
How can I do?
