My code increments a Point array using a predetermined NodeLength, I;ve searched online and can find no unclunky way of incrementing it beyond this:

 1  2  3  4  5  6  7  8  9  10 `double px = Point[1].getX();int 1x = (int) px;double py = Point[1].getY();int 1y = (int) py;1x += nodeLength;1y += nodeLength;Point[2].setLocation(1x,1y)`

There's got to be a better way than that right?

Point[2].setLocation( Point[1].getX() + nodeLength, Point[1].getY() + nodeLength );

 1  2  3  4  5  6  7  8  9  10 `Point {   ...   add(int x, int y) {      this.setLocation( getX() + x, getY() + y );   }   set(Point p, int offset) {      this.setLocation( p.getX() + offset, p.getY() + offset );   }}`

Or something along those lines?

which was my first solution but point.getX() returns a double so you can't add an int to it

SOLVED!

Point.x returns the x value as an int.

also, I'M AN IDIOT.

You seem to not be very familiar with the Java literal types and basic OO. I suggest you become more familiar with those before jumping to graphics.
