Hi I need to write a simple method that uses two booleans, "leftClicked" and "rightClicked". It's pretty self explanatory but I want leftClicked to be true when the left mouse button is down and "rightClicked" to be true when the right mouse button is down. Anyone know how to achieve this?

Also, I need a method that gets the angle that points to the mouse, from a certain point (400, 300).

As far as 'leftClicked' and 'rightClicked', check out the Greenfoot API on MouseInfo. Also, there are five methods within the Greenfoot class that deal with getting info from the mouse. For angle to mouse, use standard trigonometric functions.

I understand the trigonometry, it would be something like tan^-1(xlength/ylengnth), but how do I write that in greenfoot / java as a method or void.

Check out the discussion at www.greenfoot.org/topics/220. The basic code for the angle (and distance) is given there.
