First, import the package "java.awt.event.*". Make an inner class that implements the interface, "MouseWheelListener." Inside that inner class, create a method that has the title, "public void mouseWheelMoved(MouseWheelEvent e)" This method will be executed whenever you roll your mouse wheel. "e" is the variable that stores the information of your current mouse wheel movement.

I tried using the technique you suggested and got no results when I implemented it, should the class be implemented directly into the world code? Implemented as a seperate class file? Does it need to extend or implement anything else important?

Ah, fixed it. I needed to add it into the world panel by using: WorldHandler.getInstance().getWorldCanvas().addMouseWheelListener(myScrollingListener);
