What if Unity3D was Unity2D?

photo002The challenges behind the development of a 2D game are not the same as those in a 3D game. Unity have addressed these issues, and have announced the inclusion of a number of 2D specific tools for developers will ship in the upcoming Unity 4.3.

The four main areas that will be addressed are flat graphics, physics in a 2D world, animation, and collision detection.

Previewing a ‘lab’ build of the 2D elements to the audience at Unite 2013 in Vancouver, an appreciative audience played spot the new buttons. Starting with a 2D button to create a true ‘flat’ land in the Unity scene picker, Unity also adds in a sprite editor, and a new 2D physics engine that includes an improved polygon collision generation focused on the needs of 2D elements.

Nope, it didn’t get an ‘ooh’ from the audience either, but I suspect that once people start to see the impact on this in their huge 3D projects, this is going to be a welcome addition.

Once Unity 4.3 is released, the addition of 2D to Unity is going to make the middleware an attractive choice for many developers – 3D is popular, but it’s not a requirement. This represent a new area for Unity to expand into. If you wondered where growth for the game engine was going to come from in 2013 and 2014, here’s your answer.
