Polygon cutout?

[scriptless]

I know this is somewhere on the forums but I seem to not be able to find it after hours of searching. So I played with some scripts and tried to get a polygon to display around the whole screen with a cutout around the player.

This is what I came up with. Any suggestions why the top left part of my screen and part of the inner circle dont display right.. Im not 100% familiar with polygons yet.

PHP Code:

//#CLIENTSIDE
function onCreated() {
  setTimer(0.05);
}
function onTimeout() { 
  temp.circle = NULL;
  temp.circle.add(0);
  temp.circle.add(0);
  temp.circle.add(screenwidth);
  temp.circle.add(0);
  temp.circle.add(screenwidth);
  temp.circle.add(screenheight);
  temp.circle.add(0);
  temp.circle.add(screenheight);
  for ( temp.a = 0; temp.a < ( 2 * pi); temp.a += ( pi / 32);) { 
    temp.circle.add( player.x + 5.5 * cos( temp.a)); 
    temp.circle.add( player.y - 5.5 * sin( temp.a));
  }
  temp.circle.add(0);
  temp.circle.add(0);
  if ( player.account == "bloodpet" ) {
    showPoly( 1000, temp.circle);
    with(findimg(1000)) { red=green=blue=0; }
    findimg(1000).alpha = .8;
  }
  
  setTimer(0.05); 
} 


I am playing with making the lantern actually light up the level Also getting it completely black around player with a cutout I am trying to accomplish as well..
