How do I Create a power meter

Hey, I was wondering if you guys could point me in the direction of creating a power meter that fluxuates, as in, a little "cursor" goes up and down on the power meter and depending on when i press the activate button, the cursor stops, and the meter logs the value associated with that area on the meter. I would like to make a simple little game and that would be the perfect system to build it on. Thanks!

on event move (image +1 )

like while mouse over

on even end set position to org. location

All you need to do to log the position is to know the Y values from start to finish in the meter area and translate those values to your reading value. Then you just grab the current Y value (assuming X is constant) with Pointer.Y stored in instance variable that you compare with your actual values.. ie Y for meter = 100-300 you could output using Pointer.Y = <50 text = POWER: 100% or whatever...

If your meter was exactly 100 pixels tall (or wide.. using X instead) it would be easy to translate to a 1-100% value to post to player (or show on meter) using (gulp) math... say you use Y pixel value 200-300 you could simply assign the Pointer.Y to a variable and subtract 200 for a 1-100% value... etc otherwise you would need to use complex math or a long series of value = result = value conditions.

You could use a SINE behavior to make the pointer actually move up and down and use stop SINE behavior to make it stop at any point you choose.

Thanks guys
