Time for action – preparing the world

Let's get started with preparing the world for the Angry Birds game:

2. Next, import the starting assets for this chapter and create some folders to keep everything organized.

3. In Unity, it is very easy to turn a game from 3D to 2D. Simply select the Main Camera object that is by default present in every new scene, find the Projection value, and select Orthographic from the drop-down list.
