So, this is it! Finally, we move from the 2D world to 3D. With SceneKit, we can make 3D games quite easily, especially since the syntax for SceneKit is quite similar to SpriteKit.
When we say 3D games, we don't mean that you get to put on your 3D glasses to make the game. In 2D games, we mostly work in the x and y coordinates. In 3D games, we deal with all three axes x, y, and z.
Additionally, in 3D games, we have different types of lights that we can use. Also, SceneKit has an inbuilt physics engine that will take care of forces such as gravity and will also aid collision detection.
We can also use SpriteKit in SceneKit for GUI and buttons so that we can add scores and interactivity to the game. So, there is a lot to cover in ...
