Hi
I want to have a really smooth scrolling camera - a bouncing ball with speed constantly set to the distance it is (in pixels) from the player object.
How can I find the distance between the camera and the player object?

With the advanced direction object. Alternatively, if you're not keen on using extensions for these sorts of equations, then use the following formula:
Sqr( ( X( "Object 1" ) - X( "Object 2" ) ) pow 2 + ( Y( "Object 1" ) - Y( "Object 2" ) ) pow 2 )
In which case Object 1 would be the camera, and Object 2 would be the player. Or vice versa. Shouldn't which is which in this situation.

Is the camera a separate object?
Distance = Abs(X("Player")-X("Camera"))
Or if you want X and Y scrolling...
Distance = Sqr((X("Player")-X("Camera"))pow 2+(Y("Player")-Y("Camera"))pow 2)
Or if you need the distance between the player and the edge of the window...
Distance from top = Y("Player") - Y Top Frame
Distance from bottom = Y Bottom Frame - Y("Player")
Distance from left = X("Player") - X Left Frame
Distance from right = X Right Frame - X("Player")

Heh. Your response was slightly more elaborate.

Download Snippet Manager 2 by Sketchy. It comes with a bunch of useful formulae like this.
