RE: [Flashcoders] dynmically adding waves together problem

[Cor]

I draw my wave with this class:

package com.codobyte.display{
/*
@class:         Sinus

@author:        Cor van Dooren

@usage: Draw sinus dynamically
@syntax:        var s:Sinus= new Sinus(params);
@params:        positieX:int=0,
                positieY:int=200,
                lengte:int=200,
                hoogte:int=200,
                kleur:uint=0x000000,
                lijndikte:int=2
@methods:       s.startWave();
                s.stopWave();                                   
*/
        import flash.display.*;
        import flash.events.*;

        public class Sinus extends Sprite {

                private var positieX:int;
                private var positieY:int;
                private var hoogte:int;
                private var lengte:int;
                private var kleur:uint;
                private var lijndikte:int;
                private var val:int;

                public function Sinus(positieX:int=0, positieY:int=200,
lengte:int=200, hoogte:int=200, kleur:uint=0x000000, lijndikte:int=2) {
                        this.positieX=positieX;
                        this.positieY= positieY;
                        this.lengte= lengte;
                        this.hoogte= hoogte;
                        this.kleur= kleur;
                        this.lijndikte=lijndikte;
                        val=0;
                        if (stage) {
                                init(null);
                        } else {
                                addEventListener(Event.ADDED_TO_STAGE, init,
false, 0, true);
                        }
                }//end CONSTRUCTOR

                private function init(e:Event):void {
                        removeEventListener(Event.ADDED_TO_STAGE, init);
                        graphics.lineStyle(lijndikte, kleur);
                        graphics.moveTo(positieX, positieY);
                        addEventListener(Event.REMOVED_FROM_STAGE, stopWave,
false,0,true);
                }
                public function startWave():void {
                        addEventListener(Event.ENTER_FRAME, enterframe,
false, 0, true);
                }

                public function stopWave():void {
                        removeEventListener(Event.ENTER_FRAME, enterframe);
                        removeEventListener(Event.REMOVED_FROM_STAGE,
stopWave);
                }

                private function enterframe(e:Event):void {
                        tekenSinus(val+=2);
                }

                private function tekenSinus(psdValue:int):void {
                        graphics.lineTo(positieX+psdValue+2,
positieY+hoogte*Math.sin(psdValue*360/lengte * Math.PI/180));
                }
        }
}

So how would I fit this in?
Reagrds,

It would seem to me that you are drawing the two waves with some kind of
sine function.

Y1 = Sin(x1+Phase1)
Y2 = Sin(x2+Phase2)

So all you have do to create the third is
Y3 = Sin(x1+Phase1) + Sin(x2+Phase2)

Remember of course that Y3 will have a max/min of +2/-2 assuming of course
that originals are +1/-1 range as they should be with no amplitude
adjustment.

Hi All,
 
I need to draw waves dynamically which can be influenced at runtime.
These waves then have to add together and show the result in a third wave.
 
Here you can see the problem graphically:

Every help is welcome!
