put this code in a movie, it will help you see how the arc is drawn in flash using two end points and a control point.



this.onMouseMove = function(){
// clear all previous drawing
clear()

// arc
lineStyle(2,0x000000,100)
moveTo(0,0) // start point
curveTo(_xmouse,_ymouse,300,0) // control point is mouse, end point 300,0

// lines
lineStyle(1,0x000000,50)
moveTo(0,0) // start line 1
lineTo(_xmouse,_ymouse) // line 1 to mouse, starts line 2
lineTo(300,0) // line 2 to end point

updateAfterEvent()
}


this uses two points 300 px away from each other (one on left the other on the right at 300 px) and the mouse to make a curve. Included are 2 straight lines drawn to the mouse as a comparison.

move the mouse around and see how the curve is drawn to help you see how one would be made if drawn in flash with any given control point
