Specs
Pros
Pro Visual State Machine Editor
The visual state machine editor in GooCreate enables the addition of advanced interactivity without having to directly code it in JavaScript. Artists can add movement to objects, react to clicks and other events or even trigger changes in other state machines via events.
Pro Integrated physics engine (Cannon.js)
GooCreate is tightly integrated with the Cannon.js physics engine making it super simple to add advanced physics simulations to any project. Cannon.js is available at http://www.cannonjs.org/.
Pro Open game engine and physics engine
The Goo.js engine is fully open source and available at https://github.com/GooTechnologies/goojs
Pro FBX model importer supporting embedded textures and skin based animation
Pro Custom publishing template CSS and JavaScript
Usually when publishing you are forced to use a template provided by the service (with a logo, social buttons, etc) or you have to download the project to customize it. In GooCreate you can pick from a few different configurable templates and then, if that is not enough, you can add custom CSS and JavaScript that gets added to the page header (i.e. JS and CSS will be run/applied before the scene even starts to load) letting you style the loading screen and any other aspects of the page without having to download anything and still being able to make use of the hosting service GooCreate provides.
