[Closed] commmand execution on object selection?

What you want to do is create a callback on the #selectionSetChanged event. See below:

-- This is needed to make sure you don't create more then one instance of the callback.
       callbacks.removeScripts id:#yourUniqueID;
       callbacks.addScript #selectionSetChanged "yourFunction()" id:#yourUniqueID;

   So in a practical application would be as follows:

-- This is needed to make sure you don't create more then one instance of the callback.
       callbacks.removeScripts id:#reportNameAndSize;
 callbacks.addScript #selectionSetChanged "for eachObj in selection as array do (print eachObj.name; print (distance eachObj.max eachObj.min))" id:#reportNameAndSize;

   However to make it simpler you should make a function that is called rather then writing it all out in the string input:

function reportNameAndSize inputObjs =
      (
      for eachObj in inputObjs as array do
    	(
    	print eachObj.name;
    	print  (distance eachObj.max eachObj.min);
    	);
      );
   
       -- This is needed to make sure you don't create more then one instance of the callback.
        callbacks.removeScripts id:#reportNameAndSize;
        callbacks.addScript #selectionSetChanged "reportNameAndSize selection;" id:#reportNameAndSize;
