Why is this undefined? What am I missing?

When I run this: on('change:attribute', function(obj) { log('-----'); log(obj); log(obj.name); }); I should be getting in the last log message, the name of the attribute changed, but I get this: "-----" {"name":"Endurance","current":"18","max":"25","_id":"-JLQBakpbPC9YIUXPWN3","_type":"attribute","_characterid":"-JLQ9M6znWs1Wh1R7Us_"} undefined What am I doing wrong here?

Try obj.get("name"). From <a href="https://wiki.roll20.net/API:Objects#Types_of_Objects" rel="nofollow">https://wiki.roll20.net/API:Objects#Types_of_Objects</a>

Derp! That works. So the object I'm given is not actually an object? Weird. Thanks!

But then when I get the previes 'current' value, .get() doesn't work, I have to use dot notation, because it's an INT for some reason. i r so confus.

Roll20 objects are specialized, and you need to use the get function to get any of the attributes except id. However, the previous state of an object which is passed to the change event handler callback is not a Roll20 object, because it is no longer representing anything that's actually on the VTT.
