The last stage of the character is its code class. The code class will receive input from the PlayerInput class we wrote earlier, so the character can be controlled through the input and filter out the type of GameObjects that collided with from the parent of that collider type.

Perform the following steps:

To start with, navigate to the Assets/Scripts folder and right-click on it. Select Create and then C# Script. Name it Character.

    public Character GameCharacter;

We also need to tie the function that will call GameCharacter when PlayerInput gets a new one. At the bottom of the CalculateTouchInput function, add the following code:
