Question

Please help  to draw curves in flash pro cc,considering center and radius as parameters...

Answer 1

function drawArcF(sp:Sprite,centerX:int,centerY:int,radius:int,startA:int,endA:int,color:uint):voi d{
    if(startA>endA){
        var tempA:int=startA;
        startA=endA
        endA=tempA;
    var degToRad:Number = Math.PI/180;
    with(sp.graphics){
        lineStyle(0,color);
        moveTo(centerX+radius*Math.cos(degToRad*startA),centerY+radius*Math.sin(degToRad*startA)) ;
        for(var i:int=startA+1;i<=endA;i++){
            lineTo(centerX+radius*Math.cos(degToRad*i),centerY+radius*Math.sin(degToRad*i));
