What is Orthello

Orthello is a 2D Framework for Unity3D, written in C#. It is an easy way to add 2D images ( sprites ) and animations to your Unity3D scenes and let them interact with each other ( collisions ) or with the user/player ( user-input ). 

Images can be grouped into sprite sheets and sequence of images can be specified as animations.

There are lots of possibilities to play animations like: setting fps or duration, play #n number of times, play looping animation, ping-pong animations. Because an animation consists of one or more animation framesets ( container plus frame range ) you can create long animations that span across multiple sprite sheets and have full control over the entire sequence of your animations. Also, because it is possible to quickly play a single (looping) frameset, you could use framesets to organise your 'related' animation sequences in one animation object. You could even put all your sequences as framesets in only one animation object, as long as they don't span.

Adding objects like sprite sheets, animations and sprites to create a new scene  is usually done by dragging the corresponding object onto your scene and configuring it's settings. Although drag-n-dropping objects is the easy way, it is also possible to create your objects from scratch at runtime by code using the static functionality of the helper ref:OT class.

Controlling sprites and animations by integrating your own application C# or Javascript JS code let you quickly create 2D games an applications that you can deliver to all Unity3D platforms like : WWW, Windows, Mac, iOS and android.

Orthello is always using an orthographic camera instead of the  'normal' 3D perspective camera. The Unity3D camera is managed for you by  Orthello and you have full control over the 2D view using the ref:OTView class. You can use the view to do things like: zooming, following a target, auto pixel perfect or auto scaling.

The Orthello framework with the base classes is 100% free and the orthello.unitypackage can be downloaded on our website or from the Unity3D Asset store.

We plan to release additional Orthello products for a few dollars, that  will accelerate the production time of your 2D games or  applications even more.
