Hello,
I have a problem with 2D buttons. In my project I started with a play button which starts the animation when it is clicked - this worked. Now a slider was integrated which controls the animation by dragging the knob of the slider - this worked as well. But unfortunately when the slider was integrated, the play button didn't work any longer. Why does this happen, where is the problem??

I think you're right, the problem is about play() in the play button and the gotoAndStop() in the enterframe. How could this be solved? Maybe you could help me with the code:

// Play-button
btn_play.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void
{
MovieClip(root).3D_action.play();
}

// Slider
sliderKnob.addEventListener(MouseEvent.MOUSE_DOWN, startDragging);
function startDragging(event:MouseEvent):void{
    sliderKnob.startDrag(false, boundsRect);
}

sliderKnob.addEventListener(MouseEvent.MOUSE_UP, stopDragging);
sliderKnob.addEventListener(MouseEvent.MOUSE_OUT, stopDragging);
function stopDragging(event:MouseEvent):void{
    sliderKnob.stopDrag();
}

// Animation-control
sliderKnob.addEventListener(Event.ENTER_FRAME, onEnterFrameDown);
function onEnterFrameDown(event:Event):void {
    scrubMovie();
}

function scrubMovie():void {
    frame = Math.round(sliderKnob.x * frameFactor);
    MovieClip(root).3D_action.gotoAndStop(frame);
}

Hello Ivan,

thanks for your reply. I made some modifications and now both things work, the animation starts when click on play-button and the control of the animation with the slider works.

But still there is one problem to solve: When the animations is startet, the knob of the slider should move according to the position in the animation. Here is the code, I tried:


btn_play.addEventListener(MouseEvent.CLICK, play_klick);

function play_klick(event:MouseEvent):void{

    3D_animation.play();
    scene.addEventListener( Scene3D.UPDATE_EVENT, update_pos );
   
}

var vid_pos:int;   

function update_pos(e:Event):void{

    vid_pos = Math.round(modell.currentFrame * boundWidth / modell.frames.length + trackX); 
    sliderKnob.x = vid_pos;

}

Why doesn't it work?
