Interaction Basics

Interaction through player input is controlled through an Input class.

Easy shortcuts can be set up through the Input Manager.

Open your Input Manager through the taskbar > Edit > Project Settings...

This will open a new window/tab. Select Input Manager and twirl down the Axes menu.

Twirl down one of the Axes listed to reveal default controls:

Default settings for the Horizontal axis (for Keyboard)

Default settings for the Mouse X axis (for Mouse control)

Default settings for the Jump button (for Keyboard)

This is where you can access the sensitivity for mouse, keyboard, and controller buttons as well as what buttons control the axis/button.

These can now be accessed through using Input.GetAxis() as a value that is positive or negative and Input.GetButton() as a bool value (true/false).
