I am trying to use an action button where if the student either draws or uses the text on the sketch tool, the answer reveals itself. So far I can only get the answer to appear if they draw on the sketch. Is there anyway to code it for this to work? Below is the code I have tried so far:

hidden: when (choice1.isSelected(1)) and button1.timeSincePress\>0 and sketch1.sketch.totalStrokeLength\>0 or sketch1.sketch.pointCount\>0 false otherwise true

If that ability exists, it doesn’t appear to be in the documentation yet:

I can confirm. No sinks or sources for text in sketch _yet_.
