I need help getting information from the mouse like the mouse's X and Y coordinates. I can get the code to compile, but when it runs I get a nullPointerExeption error message. Can anyone help me? Thanks.

I am not able to get any information from the mouse
'Greenfoot.getMouseInfo()' will return 'null' unless some mouse action has been registered (movement, button press or release, etc). So, before trying any MouseInfo methods on the object, make sure that it is not 'null':
MouseInfo mouse = Greenfoot.getMouseInfo();
if (mouse != null)
{
int mouseX = mouse.getX();
int mouseY = mouse.getY();
// etc.
