    draw dynamically




      in my flash movie i have a rectangle which represents a seek bar of an audio player. on this rectangle i want to draw "points" or smaller "rectangles" at a specific place. these "points", should be placed at specific timemarks, which i have in a variable. these "points" should also be able to have a mouse-over-effect.


      this is the first time i want to draw something dynamically in flash, therefore i have no idea what would be the best practice to do so.


      it would be really appreciated if someone can point me to the right direction.

          okay let's try it another way:


          let's say i have a movieClip called "drawArea" on my stage. how can i draw a line WITHIN this movie clip? so that the reference point for moveTo and lineTo methods are the movie clip's coordinates..


          thanks very much.




          i tried it with the following code but the rectangle i want to draw gets overlapped by the original-movieclip which already exists. the orinigal mc has a depth of -16383 and my dynamically drawed mc has a depth of 1


          rectangle_mc._x = 100;
          rectangle_mc._y = 100;
          drawRoundedRectangle(mymc, 240, 18, 20, 0x99FF00, 100);
          function drawRoundedRectangle(target_mc:MovieClip, boxWidth:Number, boxHeight:Number, cornerRadius:Number, fillColor:Number, fillAlpha:Number):Void {
              with (target_mc) {
               mymc.createEmptyMovieClip ("test", 1)
                  beginFill(fillColor, fillAlpha);
                  moveTo(cornerRadius, 0);
                  lineTo(boxWidth - cornerRadius, 0);
                  curveTo(boxWidth, 0, boxWidth, cornerRadius);
                  lineTo(boxWidth, cornerRadius);
                  lineTo(boxWidth, boxHeight - cornerRadius);
                  curveTo(boxWidth, boxHeight, boxWidth - cornerRadius, boxHeight);
                  lineTo(boxWidth - cornerRadius, boxHeight);
                  lineTo(cornerRadius, boxHeight);
                  curveTo(0, boxHeight, 0, boxHeight - cornerRadius);
                  lineTo(0, boxHeight - cornerRadius);
                  lineTo(0, cornerRadius);
                  curveTo(0, 0, cornerRadius, 0);
                  lineTo(cornerRadius, 0);
          trace (mymc.getDepth());
          trace (mymc.test.getDepth());

            Ok, for your first question you can use lineTo and moveTo inside a movie clip by using this:




            This of course draws nothing, but the (0,0) is inside the movie clip and therefore equal to (my_mc._x, my_mc._y). But you have to remember that now all your other movements, lines, and curves are all relative to this point.


            For you second question i don't fully understand what you mean by "gets overlapped by the original-movieclip", but I you might try replacing your 7th line with this:


            mymc.createEmptyMovieClip ("test", mymc.getNextHighestDepth())


            This will put your "test" movieclip on the top of everything inside your mymc movieclip. If this doesn't work, you could try replacing "mymc" with "_root", but that might not be what you want.


            Hope this is helpful
