Cycling through selected tokens?

Hi all (Aaron XD) I'm looking at the GroupInitiative script to try and understand how to cycle through each selected token doing stuff. But not quite there yet. Gonna do a tuturial on underscore.js before continuing

Torch is probably easier to follow. Look for msg.selected. 

If you do a log (msg.selected); and then copy paste that into a javascript beautifier or something... it will expand it into a much more readable format.

Here's an annotated way of doing it: _.chain(msg.selected) // Start a chain of the selected objects .map(function(s){ return getObj('graphic',o._id); // try to get each as a graphic (will be undefined for drawings, text, etc }) .reject(_.isUndefined) // Remove those selected objects that were not graphics (drawings, text, etc) .each(function(t){ // Do something with the token t log( 'name: '+t.get('name'); });

Okaaay :D, wizards! Wizards all! -- Ok, almost. Not there yet   case '!selected-money': m_obj = _.chain(msg.selected) // Start a chain of the selected objects     .map(function(s){         return getObj('graphic',s._id); // try to get each as a graphic (will be undefined for drawings, text, etc     })     .reject(_.isUndefined) // Remove those selected objects that were not graphics (drawings, text, etc)     .each(function(t,m){         m.maintenance += t.get('bar1_value');         log(' ' + t + ' ' + m + ' ' + t.get('bar1_value') + ' ' + m.maintenance);         return m;     },{ maintenance: 0}); sendChat('','Maintenance total of selected units: ' + m_obj.maintenance); break; gives For reference, the error message generated was: /home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:1 orts, require, module, __filename, __dirname) { function g(a){throw a;}var j=v ^ ReferenceError: m_obj is not defined at handleInput (evalmachine.<anonymous>:195:23) at eval (

With "use strict", you must declare variables before using them: var m_obj = ... Also, for what you want, you'll need to switch the .each() to a .reduce(), put the arguments as (m,t), then add a .value() after the .reduce(). 

yeah, this could be done with .each(), but .reduce() is perfect for this Now, the need for forcing the variables to "be" numbers (with parseFloat() or by multiplying each with *1) so that they are summed instead of concatenated was quite a bitch to figure out case '!selected-money': var m_obj = _.chain(msg.selected) // Start a chain of the selected objects .map(function(s){ return getObj('graphic',s._id); // try to get each as a graphic (will be undefined for drawings, text, etc }) .reject(_.isUndefined) // Remove those selected objects that were not graphics (drawings, text, etc) .reduce(function(m,t){ return parseFloat(m) + parseFloat(t.get('bar1_value')); },0) // initializing the reduce's value to 0 .value(); sendChat('','Maintenance total of selected units: ' + ' ' + m_obj); break;
