running accuracy display

[Tyler Peckenpaugh]

Is it possible to access the participant's current accuracy up to a given point? That is, I want to display my participants' accuracy on a secondary task to them as they continue forward, e.g. on each slide, "You are at XYZ% accuracy."

I'm not sure how to access response data within my mxml markup.

Thanks for any advice.

maybe this examples helps: http://reactiontimes.wordpress.com/2013/03/26/counterbalancing-in-scriptingrt-and-new-version-0352/

the example uses items.correct and items.total. in addition, you can access

items.incorrect, items.miss, items.sum, items.avg, items.count

if I remember correctly....

Hi again,

I am hoping to use something like the following function to set the width of a canvas object: 

// return value is a percentage of 300px width

private function checkAcc(items:Object):Number{

var acc:Number;

if(items.total > 0){

acc = (Math.round((items.correct / items.total)*100))*3;

}else{

acc = 300;

}

return acc;

}

However, I am having trouble getting it to work. Specifically, I don't know what to pass as a parameter to the function so that I can access item.total and item.correct. For example:

<mx:Canvas id='feedbackbar' width="{checkAcc(param)}" height="20" verticalCenter="280" horizontalCenter="0" backgroundColor="0x00FF00"/>

Thanks for any advice,

Tyler
