Re: [flexcoders] Filled Polygon

[Adam Royle]

Sorry, you are right, I didn't study your code in great detail. Are you able to 
post a full code sample that shows your drawing commands in action?

Cheers,
Adam

  Hi!

  Thanks for the advice!

  If you look at the code a bit closer (I know it's a bit complex)  You would 
see that the moveto is only done on the first point in the loop.

  I believe the code does follow you advice as this example will show.

  Suppose I have a 4 point array:
          point[0] { 1,1}
          point[1] { 2,2}
          point[2] { 3,1}
          point[3] { 1,1}

  The the code would run the following commands
         moveto (1,1)
         beginFill
         lineto(2,2)
         lineto(3,1)
         lineTo(1,1)
         endFill

  Which should draw a filled triangle, but all I get is the lines, no fill.

      Hi Carolyn,

      I would say that it's because you are calling

      graphics.moveTo 
      and 
      graphics.beginFill

      during your loop, whereas it should be graphics.lineTo

      Change your logic so that you do this (pseudo-code):

      clear 
      lineStyle

      moveTo - (starting point)

      beginFill

      loop { 
      lineTo - (each point) 
      }

      moveTo - (optional end point)

      endFill

      Hope this helps.

      Cheers, 
      Adam

      Hello,

      For some reason I can not seem to get my polygon created by lineto to 
fill.

      The polygon gets drawn, but the fill never happens. Does anyone have any 
      suggestions?

      The code I am using is bellow:

      recColor = 0xFF0000; 
      transp=0.5; 
      var graphics:Graphics = recShape.graphics; 
      graphics.clear(); 
      graphics.lineStyle(3,recColor,100); 
      graphics.beginFill(recColor,transp); 
      var lastPoint:Point = null; 
      for(var i:int=1; i< points.length; i++){ 
      var p1:Point = new Point() 
      p1.x = points[i-1].x; 
      p1.y = points[i-1].y; 
      var p2:Point = new Point(); 
      p2.x = points[i].x; 
      p2.y = points[i].y; 
      if (lastPoint == null){ 
      graphics.moveTo(p1.x,p1.y); 
      graphics.beginFill(recColor,transp); 
      } 
      graphics.lineTo(p2.x, p2.y); 
      lastPoint = p2;

      } 
      graphics.endFill();

      Thanks!
