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

[animator_one]

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.

Regards,

JC

Thanks for that!

Any idea how to set an instance name when we add the new MC?

You're welcome!

In the example above, you could write

platform.name = "desiredName";

But if you're adding instances at runtime, you can just reference the variable directly (in this case, just platform).

Or please provide more details if this is not the answer you're looking for.

Regards,

How could I add code from an external class to platform?  If platform is going to be on the screen many times... I have a bunch of functions that I would like to assign to platform as it gets added to the stage.  platform.class = externalClassName;  I am doing what the previous person said. I have movieclips in Flash that previously had a lot of code attached to them. Now in Animate 22, I have the movieclip in the library. I'm adding them to the stage. Now I'd like to just assign them a class somehow.
