Change an element of entire array at once?

I have this game I’m making that has an array of “falling” stars. The part where I want the stars to move looks like this:


function game():void 
			{
				counter = 0;
				do {
					star[counter].y += .1;
					counter++;
				}while (counter < 56);
			}

But this only moves one star at a time, causing the falling movement to be choppy. Any way I can move the entire array at once, keeping movement smooth?
