Cylonjs+LeapMotion+bebop

[jhung]

Actually, that error is caused by an issue with the Javascript you're running. Could you post the code you're using?

20 minutes ago this code work correctly:

 var Cylon = require('cylon');

Cylon.robot({
  connections: {
    bebop: { adaptor: 'bebop'},
    leapmotion: { adaptor: 'leapmotion' }
  },

  devices: {
    bebop: { driver: 'bebop',connection: 'bebop'},
    leapmotion: { driver: 'leapmotion', connection: 'leapmotion'}
  },

  work: function(my) {
    my.leapmotion.on('frame', function(frame){
            if(frame.hands.length > 0){
                my.bebop.takeOff();

                

            } else {
                my.bebop.land();
            }


            if(frame.valid && frame.gestures.length > 0){
                frame.gestures.forEach(function(g){
                    if(g.type == 'swipe'){
                        var currentPosition = g.position;
                        var startPosition = g.startPosition;

                        var xDirection = currentPosition[0] - startPosition[0];
                        var yDirection = currentPosition[1] - startPosition[1];
                        var zDirection = currentPosition[2] - startPosition[2];

                        var xAxis = Math.abs(xDirection);
                        var yAxis = Math.abs(yDirection);
                        var zAxis = Math.abs(zDirection);

                        var superiorPosition  = Math.max(xAxis, yAxis, zAxis);

                        if(superiorPosition === xAxis){
                            if(xDirection < 0){
                                console.log('LEFT');
                                my.bebop.left();
                            } else {
                                my.bebop.right();
                                console.log('RIGHT');
                            }
                        }
                    }
                    })
                    
                }
      })
  }
}).start();

If your code worked 20 minutes ago and you haven't made any changes to your code, try rebooting your machine to see if that helps.

[canci98]

ok I rebooted the machine and running the program properly, but when I tried to re-run Cmd back the same mistake, how can I fix this? The only solution is to restart the machine any time I want to run the project?

[jhung]

There's an issue with your Cylon JS that is spawning a process that doesn't properly exit cleanly. You'll need to debug yourself for a more permanent fix but if you can track down what process is spawning, whether that be node or a browser or something else, and kill the process, you should be able to temporarily get around the issue

I've moved your thread to the developer section so our community members can hopefully help you out.

[canci98]

Perfect thank you for everything you've been very kind and patient!
I hope to resolve in the section where you have moved me.

[jhung]

Happy to help! Best of luck with your project!

[canci98]

When someone can help me him post in this topic?

[canci98]

the code is this:

var Cylon = require('cylon');



Cylon.robot({
	//Creazione connessioni

	connections: {

		leapmotion: {adaptor: 'leapmotion'},

		bebop: { adaptor: 'bebop' }

	},

	//Creazione device

	devices: {

		leapmotion: {driver: 'leapmotion', connection: 'leapmotion'},

		bebop: {driver: 'bebop', connection: 'bebop'}

	},

	//Creazione funzione principale

	work: function(principale){

		principale.leapmotion.on('frame', function(frame){
			//se leap rileva la mano

			if(frame.hands.length > 0){
				//decollo

				principale.bebop.takeoff();

			} else {
				//atterraggio

				principale.bebop.land();

			}

			//se leap rileva la mano

			if(frame.valid && frame.gestures.length > 0){
				//funzione secondaria

				frame.gestures.forEach(function(secondaria){
					//riconoscimento gesto

					if(secondaria.type == 'swipe'){
						//Creazione variabili

					var posizioneCorrente = secondaria.position;

				var posizioneDiPartenza = secondaria.startPosition;

					//Creazione di come il drone dovrà muoversi

		var direzionex = posizioneCorrente[0] - posizioneDiPartenza[0];

		var direzioney = posizioneCorrente[1] - posizioneDiPartenza[1];

		var direzionez = posizioneCorrente[2] - posizioneDiPartenza[2];

		// Math.abs restituisce il valore assoluto di un valore numerico 

					var assex = Math.abs(direzionex);

					var assey = Math.abs(direzioney);

					var assez = Math.abs(direzionez);

			//restitusice il valore maggiore tra tutti quelli passati()

			var posizioneS  = Math.max(assex, assey, assez);

				//spostamenti destra e sinistra

				if(posizioneS === assex){

					if(direzionex < 0){

						console.log('SPOSTAMENTO SINISTRA');

						principale.bebop.left();

					} else {

						principale.bebop.right();

						console.log('SPOSTAMENTO DESTRA');

							}

						}

					//spostamenti in avanti e indietro

			if(posizioneS === assez){

				if(direzionez > 0){

					console.log('SPOSTAMENTO INDIETRO');

					principale.bebop.back();

				} else {

					console.log('SPOSTAMENTO IN AVANTI');

					principale.bebop.forward();

							}

						}

			//spostamenti verso l'alto e verso il basso

			if(posizioneS === assey){

				if(direzioney > 0){

					console.log('IL DRONE SI STA ALZANDO');

					principale.bebop.up(1);

				} else {

					console.log('IL DRONE SI STA ABBASSANDO');

					principale.bebop.down(1);

							}

						}
						//esegue un backflip

		} else if(secondaria.type === 'keyTap'){
			console.log('ESEGUITO UN BACKFLIP');

			principale.bebop.backFlip();

			after((5).seconds(), function(){
			//atterraggio

			principale.bebop.land();

						})

					}

				})

			}

		})

	}

}).start();

I dont know why when i put my hand over the leap motion the drone takeoff correctly and when i swipe(left or right) dont work..

can anyone help me please? if the code is not clear, tell me

[canci98]

can anyone help me please?
is for my exam
