[Xerte] How to use the judge function correctly

[Dave Burnett]

Hmm.

My interaction (id question) has 4 responses with names, id's, correct set to 1.

If I debug:
question.responses.length

I get 0

Hello
 
I don't know how this function works, but I can possibly 
help as thus
 
INTERACTION.prototype.judge = function() {
 //check 
that each response whose correct is not undefined
 //has the same status 
as correct
 for (var i = 0; i<this.responses.length; i++) 
{
  if (this.responses[i].correct != undefined) 
{
   //trace(this.responses[i].correct +" " 
+this.responses[i].status);
   if (this.responses[i].correct 
!= this.responses[i].status) {
    //doesn't match - user 
cannot have matched all correctly
    return 
false;
   }
  }
 }
 return 
true;
};
 
That is the flash source code of the function, so it 
looks like you need to set responses for the interactions for a judge to 
work.

  Hi List, 

another beginner's question. Imagine the following 
  structure: 
-- page 1 
---- interaction: id=question1 
-------- button 1: correct=0 
-------- button 2: correct=0 
-------- button 3: correct=1 
-- page 2 
---- 
  script: question1.judge() 

The 
  script returns undefined, regardless of what the user clicks. I also tried 
  false and true instead of 0 and 1. What's wrong?
