Create Movie Clip objects dynamically and add them to the Stage with javascript in HTML5 in Animate

[#1]

Basically I want to instantiate MovieClip objects and add them to the Stage using Javascript(createjs) from the Actions panel in an HTML5 Adobe Animate project. I think previously this could be accomplished by giving a linkage identifier to the MovieClip in the library and instantiating the MovieClip using that but I don't see that option now. What is the best way to do this in an HTML5 project?

Hi.

In HTML5 Canvas documents, you must assign a linkage name in the Linkage column in the Library.

Any symbol in the Library is a property from the global lib object that is automatically created by Animate when the content is published. To instantiate a symbol at runtime, you must use the linkage name as the constructor method name. Like this:

var platform = new lib.Platform();
platform.x = canvas.width * 0.5;
platform.y = canvas.height * 0.5;
this.addChild(platform);

I hope this helps.
