While running, Cenario content detects if it is iframed within another project, for example in a Lectora, Captivate, or Storyline course, and posts messages to its parent detailing what is happening in the content. All messages are posted as JSON, and are indexed by the “type” data member. The following messages are passed:

  • type - cenariovr:attempted
  • scenario - (name of scenario)

  • type - cenariovr:experienced
  • scenario - (name of scenario)
  • scene - (name of scene)
  • duration - (# of seconds in scene)

CLICKED

  • type - cenariovr:clicked
  • scenario - (name of scenario)
  • scene - (name of scene)
  • object - (name of object clicked on)

  • type - cenariovr:answered

  • questtext - (text of question)
  • choicetext - (text of selected choice)
  • iscorrect - (true or false)
  • duration - (# of seconds to answer question)

UPDATED

Sample JavaScript to catch messages from CenarioVR content

window.addEventListener('message', function(event) {
   var data = JSON.parse(event.data);
   var messagedatatype = data.type;
   if (messagedatatype=='cenariovr:attempted') {
           console.log("Scenario Attempted: " + data.scenario);
   }else if (messagedatatype=='cenariovr:experienced') {
           console.log("Scene Experienced: " + data.scene + ", Duration: " + data.duration );
   }else if (messagedatatype=='cenariovr:clicked') {
           console.log("Hotspot Clicked: " + data.object );
   } else if (messagedatatype=='cenariovr:answered') {
           console.log("Question Answered: " + data.questname + ", Correct: " + data.iscorrect  + ", Duration: " + data.duration );
 } else if (messagedatatype=='cenariovr:updated') {
           console.log("Variable Updated: " + data.variable + " :  " + data.value );
   } else if (messagedatatype=='cenariovr:finish') {
var strVars = "";
 for( var index=0; data.variables && index<data.variables.length; index++){
if( index != 0 ) strVars += ", ";
strVars += data.variables[index].name + " = " + data.variables[index].value;
}
  console.log("Scenario Finished: " + data.scenario + ", Score: " + data.score + ", Result: " + data.result + ", Duration: " + data.duration + ", Variables: { " + strVars + " }");
   }
} );
