Impact vs Goo Create

Impact provides 2 types of collision detection; static and dynamic collisions. Both of which are easily integrated into game development.

Many plugins are available, including one called Impact++ which adds features like pathfinding and dynamic lighting.

Built-in map editor with support for tiling, collision layers, and actors.

ImpactJS has an active user community that busily produces tremendous resources including videos, books, tutorials, walkthroughs and more. There are also comprehensive class documentation available.

Extending the reach of a game developed with ImpactJS is easy due to the cross-platform nature the framework. There are Considerations around performance, resolution and audio, however all can be appropriately addressed when in development. Works in the browser via Canvas, even on mobile. Easily translatable into a packaged app.

Since GooCreate is native to the Web and uses WebGL directly, finished projects usually have a much smaller (sometimes orders of magnitude) download sizes compared to tools like Unity.

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.

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/.

The Goo.js engine is fully open source and available at https://github.com/GooTechnologies/goojs

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.

Material editor supports diffuse color, normal maps, specularity, emissiveness, opacity, reflectivity and refractivity.

Post effects including bloom, motion blur, anti aliasing, levels, contrast, vignette and edge detection.
