How to add controls? (WASD)

Hello, im very new to unity and i want to know how to add controls into my game, just so i can walk around and look around. Does anyone know the code for this?

place the following code in your update loop.

if (Input.GetKey(Keycode.A))
Debug.Log (“The A key is being pressed!”);

After you get that working look into using the Input Manager to make checking for keys more generic!
