How to rotate inside a loop?

jonniemarbles

Hi everyone. New here (and new to Processing) so hope this is the right place.

I want to use a loop to create a nice symmetrical pattern (specifically, I'm trying to make a snowflake). The problem is, every time the loop goes round, the rotation is reset, so I just end up drawing the same shape over and over. Is there any way to use a loop for rotations? Many thanks.

size(400,400);
background(0);
stroke(255);
fill(255);
translate(200,200);
for(int i = 0; i < 6; i++){
  rotate(TWO_PI/6.0);
  line(20, 0, 180, 0);
  line(140,-20,140,20);
  line(130,-20,150,20);
  line(150,-20,130,20);
}
