I have voetsjoeba’s streaming player [http://www.voetsjoeba.com/lab.php?i=8](http://www.voetsjoeba.com/lab.php?i=8)  
which i modified slightly. I want to control volume with a knob instead of a slider.

my player is attached.

## here is the code for the knob:

## r0.speed = Math.random()-.5; r0.onPress = doDrag; r0.onRelease = noDrag; r0.onReleaseOutside = noDrag; r0.onEnterFrame = move; function doDrag() { this.drag = true; var dx = \_xmouse-this.\_x; var dy = \_ymouse-this.\_y; this.angle = Math.atan2(dy, dx); } function noDrag() { this.drag = false; } function move() { if (this.drag) { var dx = \_xmouse-this.\_x; var dy = \_ymouse-this.\_y; var newAngle = Math.atan2(dy, dx); this.speed = newAngle-this.angle; this.angle = newAngle; this.\_rotation += this.speed\*180/Math.PI; \_root.rot = this.\_rotation; } }

thanks for your help!!!

peace,
