When I ran this example and some rockets came to the bottom right corner of the window, it threw an ArrayIndexOutOfBoundsException at that line.
Actually
y*(width/gridscale)should be the same as
y*width/gridscale.
But as y is of type Integer, it behaves differently and causes an ArrayIndexOutOfBoundsException.
With the brackets around width/gridscale it is the same term as for the instantiation of the array
dnasize = (width / gridscale) * (height / gridscale);
