Question

If possible I would like to tile an image or MovieClip along a line using the standard moveTo() and lineTo() methods, The lines are directional so need to show something similar to >>>>>>>>>>>>>. The lines can be at any angle, so using drawRect() with beginBitmapFill() isn t an option. Also if possible I would like to have the lines animated.

Is this possible or will it require a custom class?

Answer 1

Yes, It is possible. I am assuming that by lines you mean rectangles (of certain width and are placed at certain angle let say theta.) So one way is, don t use drawRect, instead of this use moveTo and lineTo to make angled rectangles.


var matrix:Matrix = new Matrix();
matrix.rotate(theta);
graphics.beginBitmapFill(bitmapData, matrix);
graphics.moveTo(x0, y0);
graphics.lineTo(x0 + w * Math.cos(theta), y0 + w * Math.sin(theta));
graphics.lineTo(x0 + w * Math.cos(theta) - h * Math.sin(theta), y0 + w * Math.sin(theta) + h * Math.cos(theta));
graphics.lineTo(x0 - h * Math.sin(theta), y0 + h * Math.cos(theta));
graphics.endFill();

You can add as many rectangles as you want.
