          In the generated JS file where it says:


          loader.addEventListener("fileload", handleFileLoad);
          loader.addEventListener("complete", handleComplete);


          Add anywhere before the loadManifest call:


          loader.addEventListener("progress", handlePreload);


          ...where handlePreload is a function that you must provide, which will be called at regular intervals and passed a parameter between 0 and 1 representing the current percent completion. How you choose to visualize that progress is entirely up to you.

              To set this up so that it's added when you publish, in Animate CC, first go to FIles->Publish Settings...  Choose the "Advanced" tab, and select export.  Name the template.  Go to an external editor, edit the HTML template it exported.  Between lines "$CREATE_LOADER" and "$LOAD_MANIFEST" in the "init()" javascript function, add the code:

              1. loader.addEventListener("progress", handlePreload); 



              Of course, you'll have to also add the handlePreload javascript function.  Do that in this template as well.



              Once you're finished editing the template, go back to Animate CC, into Files->Publish Settings.  Choose the "Advanced" tab again, click the "Import" button, and load the HTML template you just finished editing.


              Now it will call your "handlePreload" function while it is loading the mainifest.


              Here is the full text of the template (NOTE: ppf.js is my file for ActionScript 2 polyfills, because it's easier than having to reformat the code all of the time ):


              <!DOCTYPE html>
                1. All tokens are represented by '$' sign in the template.
                2. You can write your code only wherever mentioned.
                3. All occurrences of existing tokens will be replaced by their appropriate values.
                4. Blank lines will be removed automatically.
                5. Remove unnecessary comments before creating your template.
              <meta charset="UTF-8">

              <!-- write your code here -->
              var canvas, stage, exportRoot, anim_container, dom_overlay_container, fnStartAnimation;
              //Added handlePreload here...
              function handlePreload(v){
                //You can do whatever you would like here...
              function init() {
                canvas = document.getElementById("$CANVAS_ID");
                anim_container = document.getElementById("$ANIM_CONTAINER_ID");
                dom_overlay_container = document.getElementById("dom_overlay_container");
                loader.addEventListener("progress", handlePreload);
                //This function is always called, irrespective of the content. You can use the variable "stage" after it is created in token create_stage.
                //Registers the "tick" event listener.
                //Code to support hidpi screens and responsive scaling.
