Nine Patch in WaveEngine

What is Nine-Patch?

A Nine-Patch is an image format that adds extra information on an image file, defining what parts of it should be scaled (and which are not) when the image is rendered in a larger or smaller size. This technique was introduced in the Android SDK and is very useful for creating UI components like buttons, panels, containers, etc.

Using this technique, you can define the background of multiples UI components like panels or buttons with the same image asset. You can also create large panels with a reduced image asset so is very useful for optimizing your project resources.

What’s new in Wave Engine Saw Shark (2.3.0)

New WaveEngine 2.3.0 (Saw Shark) brings a lot of new features. Although our main new feature is the new Physics 2D engine, we will expose all the new features and improvements of this version.

New Physics 2D Engine integration

WaveEngine 2.3.0 (Saw Shark) includes a native wrapper for Box2D up to 60% faster compared to our last physics engine. Furthermore the new API is faithful to the Box2D API so you can port any Box2D sample to our new WaveEngine API.

New Animation 2D and 3D GameActions

Wave Engine 2.3.0 (Saw Shark) has added a lot of new features. One of them is a new set of GameActions specialized for animating entities. In this article you may have been realized that GameActions are a really powerful and customizable way to create your own behaviors and interact with others in an easy flow, creating sequential and parallel GameActions to animate your entities. However, they relied on the user the task of creating its own animations as WaveEngine offered the architecture.

Good news is that we’ve included a complete set of GameActions in WaveEngine.Components package. That includes type animations for simple types and transform animations for rotating, scaling and translating entities.

And because they are GameActions, they can be played in sequential order or parallel to others.

WaveEngine 2.2.1 to 2.3 Cheat sheet

In the last WaveEngine 2.3.0 version has been added Box2D physics engine as native integration. It allows a lots of new physics features and a better performance but it brings many API changes.

WaveEditor has a Upgrader Tool that automatically upgrade your project files to last WaveEngine version but doesn’t modify your source code. So you can find some issues after upgrade your project.

This article brings you a list of common issues and how to solve them:

RigidBody and Colliders

WaveEngine 2.2.1

[code language=”csharp”]
new RigidBody2D()
PhysicBodyType = PhysicBodyType.Static

WaveEngine 2.3.0

[code language=”csharp”]
new RigidBody2D()
PhysicBodyType = RigidBodyType2D.Static

Box2D integration in WaveEngine 2.3.0

Box2D is a 2D physics engine for games, for more related help, please visit

Now, in WaveEngine 2.3.0, we have integrated Box2D as 2D Physic engine. In previous versions, we use Farseer Physics (C# reimplementation of Box2D Farseer is a great tool, but we decided to step forward and include a 100% native physic engine.
