William Haynes on Truss: zero force members 6 days, 18 hours ago

Saved a checkpoint:

Figured out how to to access the ggb app in the preamble

var v = question.scope;
try{
var app = v.variables.truss.app

Still doesn't work because of misdirected clicks on the ggb diagram.

Saved a checkpoint:

Changed question.signals.on('adviceDisplayed' ... function,  so that function can find the applet again to hide zero force members.   See var app = 

This doesn't seem very robust to me, probably won't work if the page has multiple applets, and this one has a different identifier.

Still doesn't work because of misdirected clicks on the ggb diagram.

Saved a checkpoint:

Switched to geogebra_applet() instead of using an extension function. 

Replaced "choose several from a list" answer part with a custom extension part.  

Still doesn't work because of misdirected clicks on the ggb diagram.
