  # Demo DOM 006

  Tween actions on a DOM element; tracking tween and ticker activity (analytics)

- §

  Run code

      import * as scrawl from '../source/scrawl.js';

      import { reportSpeed } from './utilities.js';

- §

  #### Google Analytics

  We load GA code in the normal way through markup in the dom-006.html file (lines 11-21), and get a handle on the ga object here

      const ga = window[window['GoogleAnalyticsObject'] || 'ga'];
      let myTracker;

- §

  Create a new tracker to handle tween and ticker action/progress, and set some attributes on it. @ts-expect-error

      ga('create', 'UA-000000-0', 'auto', 'demoCanvasTracker');

- §

  We can then incorporate the tracker’s functionality in our various hook functions defined further down in this script @ts-expect-error

      ga(function() {

          const ga = window[window['GoogleAnalyticsObject'] || 'ga'];

- §

  @ts-expect-error

          myTracker = ga.getByName('demoCanvasTracker');
          myTracker.set('transport', 'beacon');
          myTracker.set('campaignKeyword', 'Scrawl-canvas demo');

- §

  Comment out the next line to send tracker packets (so they show up in the console)

          myTracker.set('sendHitTask', null);
      });

- §

  #### Scene setup

      const artefact = scrawl.library.artefact,
          stack = artefact.mystack,
          element = artefact.myelement;

- §

  Grab a handle to the ‘boat’ element, then clone it

      element.set({
          startX: 'center',
          startY: 'center',
          handleX: 'center',
          handleY: 200,
          width: 80,
          height: 42,
          text: 'BOAT',
          css: {
              border: '1px solid blue',
              borderRadius: '50%',
              textAlign: 'center',
              padding: '12px 0 0 0',
          }
      }).clone({
          name: 'mysecondelement',
          handleY: 150,
          scale: 0.9,
          css: {
              backgroundColor: 'lightblue',
          }
      }).clone({
          name: 'mythirdelement',
          handleY: 100,
          scale: 0.8,
          roll: -40,
          css: {
              backgroundColor: 'lightgreen',
          }
      });

- §

  Create tickers - testing Ticker clone and packet functionality

      const modelTicker = scrawl.makeTicker({
          name: 'modelTicker',
          cycles: 0,
          duration: '12s'
      });

- §

  Test Ticker cloning

      const ticker = modelTicker.clone({
          name: 'myTicker',
      });

- §

  Create, and start, tweens - testing Tween clone and packet functionality

      scrawl.makeTween({
          name: 'myTween',
          targets: element,
          ticker: 'myTicker',
          duration: '100%',
          time: 0,
          definitions: [
              {
                  attribute: 'roll',
                  start: 0,
                  end: 360
              }
          ]
      }).clone({
          name: 'myClonedTween',
          targets: artefact.mysecondelement,
          definitions: [
              {
                  attribute: 'roll',
                  start: -20,
                  end: 340
              }
          ]
      }).clone({
          name: 'mySecondClonedTween',
          targets: artefact.mythirdelement,
          useNewTicker: true,
          duration: '10s',
          cycles: 0,
          definitions: [
              {
                  attribute: 'roll',
                  start: -40,
                  end: 320
              }
          ]
      });

  Build timeline actions

      const red = { css: { backgroundColor: 'red' }},
          purple = { css: { backgroundColor: 'purple' }},
          brown = { css: { backgroundColor: 'brown' }},
          orange = { css: { backgroundColor: 'orange' }},
          yellow = { css: { backgroundColor: 'yellow' }},
          gray = { css: { backgroundColor: 'gray' }},
          green = { css: { backgroundColor: 'green' }},
          blue = { css: { backgroundColor: 'blue' }};

      scrawl.makeAction({
          name: 'red',
          ticker: 'myTicker',
          targets: element,
          time: '6.25%',
          action: function () { element.set(red) },
          revert: function () { element.set(purple) }

      }).clone({
          name: 'brown',
          time: '18.75%',
          action: function () { element.set(brown) },
          revert: function () { element.set(red) }

      }).clone({
          name: 'orange',
          time: '31.25%',
          action: function () { element.set(orange) },
          revert: function () { element.set(brown) }

      }).clone({
          name: 'yellow',
          time: '43.75%',
          action: function () { element.set(yellow) },
          revert: function () { element.set(orange) }

      }).clone({
          name: 'gray',
          time: '56.25%',
          action: function () { element.set(gray) },
          revert: function () { element.set(yellow) }

      }).clone({
          name: 'green',
          time: '68.75%',
          action: function () { element.set(green) },
          revert: function () { element.set(gray) }

          action: function () { element.set(blue) },
          revert: function () { element.set(green) }

      }).clone({

          action: function () { element.set(purple) },
          revert: function () { element.set(purple) }
      });

- §

  Add some Google Analytics progress actions to one of the tickers

  TODO: 0% times will fire the action function when the ticker is moving both forwards and backwards, but never fires the revert function. I don’t consider this to be a show stopper.

      scrawl.makeAction({

          ticker: 'myTicker',

          name: 'lapStarted',
          time: '0%',

          action: function () {
              if (myTracker) myTracker.send('event', 'Ticker progress', 'Ticker loop starting (forwards)', `Action ${this.name} on ${this.ticker}`) ;
          },

          revert: function () {
              if (myTracker) myTracker.send('event', 'Ticker progress', 'Ticker loop starting (reversed)', `Action ${this.name} on ${this.ticker}`);
          },

      }).clone({

          name: 'lapCompleted',
          time: '100%',

          action: function () {
              if (myTracker) myTracker.send('event', 'Ticker progress', '100% complete (forwards)', `Action ${this.name} on ${this.ticker}`);
          },

          revert: function () {
              if (myTracker) myTracker.send('event', 'Ticker progress', '100% complete (reversed)', `Action ${this.name} on ${this.ticker}`);
          },

      }).clone({

          name: 'halfwayThere',
          time: '50%',

          action: function () {
              if (myTracker) myTracker.send('event', 'Ticker progress', '50% complete (forwards)', `Action ${this.name} on ${this.ticker}`);
          },

          revert: function () {
              if (myTracker) myTracker.send('event', 'Ticker progress', '50% complete (reversed)', `Action ${this.name} on ${this.ticker}`);
          },
      });

- §

  Also add some Google Analytics code to one of the tweens

      const smallboat = scrawl.library.tween.mySecondClonedTween;

      smallboat.set({

          onHalt: function () {
              if (myTracker) myTracker.send('event', 'Tween state', 'halt', `Tween ${this.name} on ${this.ticker}`)
          },

          onResume: function () {
              if (myTracker) myTracker.send('event', 'Tween state', 'resume', `Tween ${this.name} on ${this.ticker}`)
          },
      });

- §

  #### Scene animation

  Start the tween animation

      ticker.run();
      smallboat.run();

- §

  Function to display frames-per-second data, and other information relevant to the demo

      const report = reportSpeed('#reportmessage');

- §

  Create the Display cycle animation

      scrawl.makeRender({

          name: 'demo-animation',
          target: stack,
          afterShow: report,
      });

- §

  #### User interaction

  Event listener will reverse direction on the larger boats, while halting/restarting the smallest boat

      const changeDirection = (e) => {

          e.preventDefault();
          e.returnValue = false;

          ticker.reverse(true);

          if (smallboat.isRunning()) smallboat.halt();
          else smallboat.resume();
      };
      scrawl.addNativeListener('click', changeDirection, stack.domElement);

- §

  #### Development and testing

      console.log(scrawl.library);

- §

  Test Tween object packet

      console.log(scrawl.library.tween.mySecondClonedTween.saveAsPacket())
