[java] getting fps

You should have a pair of ints in your graphical engine:

int currentFPS;
int pastFPS;

Everytime your engine renders an image, you should increment currentFPS. Your run() method in the thread should be something like this:

public void run() {
pastFPS = currentFPS;
currentFPS = 0;
try {
Thread.sleep(1000);
} catch (InterruptedException e)
The screen should show pastFPS, of course

Hope this helps

A very similar solution, without the use of Thread... why the use of _ before every variable name?

Mac for productivity
Linux for development
Palm for mobility
Windows... for the Solitaire

It''s a convention to mean that that variable is a member variable of a class declared outside of a method. So you can''t become confused as to where a variable is from. I guess.
