Input

Because we’re now at the point where we need to get input from the device, it’s time to make sure that the Unity Editor can receive input. Without this, the only way to test the game is to build the game and install it on a device, which can take a while. Unity’s all about being able to rapidly test your changes, and waiting for a build to finish will slow you down a lot.
