Making a movieclip move in relationship to another mc that's being dragged.

[SteelCurtn75]

So I have a slider that's controlling an animation that inside a mc. That's all working fine. I want the inside of the "track" that the slider is on to fill with color as it's being dragged to the right. I've set it up so there's a mask that reveals that color.

So basically I want my "fillMask_mc" to have the same x position (minus 237 pixels) as "sliderControl_mc" Below is the code I have, and it initially works when you click the sliderControl... but it doesn't move with it when you drag.

fader_mc.stop();

sliderControl_mc.knob_mc.addEventListener(MouseEvent.MOUSE_DOWN, onDragKnob);
stage.addEventListener(MouseEvent.MOUSE_UP, onReleaseKnob);

sliderControl_mc.knob_mc.buttonMode=true;

function onDragKnob(myEvent:Event):void {
    sliderControl_mc.knob_mc.startDrag(false, new Rectangle(0,0,252,0));
    sliderControl_mc.knob_mc.addEventListener(Event.ENTER_FRAME, onScrubMovie);    
    fillerMask_mc.x = sliderControl_mc.x-237;
}  

function onReleaseKnob(myEvent:Event):void {
    sliderControl_mc.knob_mc.stopDrag();    
}  

function onScrubMovie(myEvent:Event):void {
    var playHead:int=Math.round((sliderControl_mc.knob_mc.x/260*23)+1);
    fader_mc.gotoAndStop(playHead);    
}

I think you need to put this line, fillerMask_mc.x = sliderControl_mc.x-237;, outside of the function, because you always reset the the mask to one position when you drag the slider.

No dice, tried that and am getting the same issue. It puts it in the correct position initially but it doesn't move when you drag the controller.

Where is the code that moves the mask?

Maybe try something like this...

fader_mc.stop();

sliderControl_mc.knob_mc.addEventListener(MouseEvent.MOUSE_DOWN,
onDragKnob);
stage.addEventListener(MouseEvent.MOUSE_UP, onReleaseKnob);

sliderControl_mc.knob_mc.buttonMode = true;

function onDragKnob(myEvent:Event):void {
        sliderControl_mc.knob_mc.startDrag(false, new Rectangle(0,0,252,0));
        sliderControl_mc.knob_mc.addEventListener(Event.ENTER_FRAME,onScrubMovie);
}
function onReleaseKnob(myEvent:Event):void {
        sliderControl_mc.knob_mc.stopDrag();
        sliderControl_mc.knob_mc.removeEventListener(Event.ENTER_FRAME,onScrubMovie);
}

function onScrubMovie(myEvent:Event):void {
        var playHead:int=Math.round((sliderControl_mc.knob_mc.x/260*23)+1);
        fader_mc.gotoAndStop(playHead);
        fillerMask_mc.x = sliderControl_mc.x - 237 + sliderControl_mc.knob_mc.x;
}

That did it! Thanks!
