Camera tour points refresh in 3d.io


I made sortable menu of camera tour points (only jquery)

<a-entity id='cameraTour' camera tour='autoStart:false' position='21 12 -15' rotation='-35 30 0' style='display:none;'>
  <a-entity class='cameraTourPoint' tour-waypoint='Front View' io3d-uuid='frontView' position='2 10 -13' rotation='-25 0 -1.5'></a-entity>
  <a-entity class='cameraTourPoint' tour-waypoint='North Side View' io3d-uuid='northSideView' position='-25 8 -42' rotation='-45 -93 -1'></a-entity>
  <a-entity class='cameraTourPoint' tour-waypoint='South Exit' io3d-uuid='southExit' position='24 -.8 -37.7' rotation='-2 -90 0'></a-entity>
  <a-entity class='cameraTourPoint' tour-waypoint='South Angle View' io3d-uuid='southAngleView' position='21 12 -15' rotation='-35 30 0'></a-entity>
</a-entity>

For swap the camera points and menu's items i use dom manipulation functions like here:

var el = document.getElementsByClassName('cameraTourPoint')[currentItemIndex],
    elBefore = document.getElementsByClassName('cameraTourPoint')[currentItemIndex+1];
document.getElementById('cameraTour').insertBefore(el,elBefore.nextSibling);

For add new way-point i made this:

var cameraTourPoint = document.createElement('a-entity'),
    cameraPointAttributes = {
      "id": generatePointId(),
      "class": "cameraTourPoint",
      "tour-waypoint": "CLEAR POINT",
      "io3d-uuid": "clearPoint",
      "position": function() {},
      "rotation": ""
    },
    lastChild = document.getElementById('cameraTour').lastChild;

document.getElementById('cameraTour').insertBefore(cameraTourPoint,lastChild.nextSibling);
var clearPoint = document.getElementById('cameraTour').lastChild;
$.each(cameraPointAttributes,function(key,value){
  clearPoint.setAttribute(key,value);
});

but it's not working! after swap cameraTour i want to change order and when i add new point, and trying to go to him 'onclick', i get this message:

tour.js:80 The given waypoint clearPoint does not exist. Available waypoints: (4) ["frontView", "northSideView", "southExit", "southAngleView"]

So, how can I refresh tour points after swapping or adding new point?

Solution

  • probably you forgot to update the tour component take a look at the source https://github.com/archilogic-com/3dio-js/blob/master/src/aframe/component/tour.js

    and maybe you didn't wait for the new waypoint element to be created https://aframe.io/docs/0.7.0/core/entity.html#events

    this works:

    var cameraTourPoint = document.createElement('a-entity'),
    cameraPointAttributes = {
      "id": 'asd',
      "class": "cameraTourPoint",
      "tour-waypoint": "CLEAR POINT",
      "io3d-uuid": "clearPoint",
      "position": "-5 2 0",
      "rotation": "0 0 0"
    },
    cameraEl = document.querySelector('[camera]'),
    lastChild = cameraEl.lastChild;
    
    cameraEl.insertBefore(cameraTourPoint,lastChild.nextSibling);
    var clearPoint = cameraEl.lastChild;
    $.each(cameraPointAttributes,function(key,value){
      clearPoint.setAttribute(key,value);
    });
    // the waypoint dom element needs to be created
    clearPoint.addEventListener('loaded', () => {
      // update the tour component
      cameraEl.components['tour'].update()
      // move to target
      cameraEl.components['tour'].goTo('clearPoint')
    }, 100)
