tip : use another box attached to the spring user box, with only "collides with water" collision checked. this way there will be no useless, laggy water on its bottom.
the only fail in this model is : it has no "square root" button.(at least here in brazil all of em have)
but congrats. really good idea. too bad its simply too complicated to explain to some people, even the "simple" parts, like the mousepos ball spawner triggered by the left mouse button..
Bronie, ever noticed "AirFrictionMult" in the script menu?
thats the air friction multiplier. edit its number to something high and you will get the same result as the stabilizer you have made. thats much better than to clone-a-lot boxes, and it gives slightly less lag too!
