Question

Play / Pause Sequence

Hello All,

 

I know this sounds super simple, but I can't figure out how to create a play / pause function. I want a button that toggles between playing and pausing the animation. This is what I've tried so far and it's not working. I've attached the Chrome Dev tools error. It doesn't like "$scope.view.Home.wdg.pump.svc.play;"

 

// playPause
// Functionality: stop the sequence if already playing - or play the current step if already stopped
$scope.app.playPause = function() {
console.log('$scope.app.playPause = function()');
if($scope.app.view.Home.wdg.pump.playing)
{
$scope.view.Home.wdg.pump.svc.stop;
console.log('playing was stopped');
}else{
$scope.view.Home.wdg.pump.svc.play;
console.log('playing was started');
}
//app.view["Home"].wdg["pump"].svc.play
}

 

Any Ideas are appreciated!

Thanks,

Wes

    Hi @Wes_Tomer 

     

    You can use a toggle button and it's 'pressed'/'unpressed' events to do this without code. Add a toggle button to your canvas and bind the 'pressed' event to the 'playAll' service and the 'unpressed' event to the 'stop' service of your model.

    Thank you. This would be a good alternative, but it will not work in our case.
    We need the user to be able to turn their attention and hands to the physical product, while wearing the HoloLens.
    For this reason we need a button that can be pressed once (HoloLens air-tap) to play
    And pressed once to pause (to inspect part-way through)

    Ah, gotcha.

     

    Try this:

     

    Create an app param and initialize it to = 0. I called mine 'modelPlaying'. Add the below code to Home.js:

     

    var playStatus = $scope.app.params.modelPlaying;

$scope.isPlaying = function(){
 
	playStatus = 1;
 
};

$scope.notPlaying = function(){
 
	playStatus = 0;
};

$scope.toggleSequence = function(){
 console.log('in toggle Sequence');
 if(playStatus == 1){
 $scope.app.fn.triggerWidgetService('model-1', 'stop');
 console.log('stopping sequence');
 }
 else{
 $scope.app.fn.triggerWidgetService('model-1', 'playAll');
 console.log('playing sequence');
 }
}

    Call isPlaying() on the model event 'Play Started', notPlaying() on the 'Play Stopped' event, and toggleSequence() on the click event of your button.
