Unity's modern Input System separates physical controls from game actions.

Key concepts:

• Device: keyboard, mouse, gamepad, etc.
• Control: a specific key, button, stick or axis.
• Input Action: a logical action such as Move, Jump or Attack.
• Binding: connects a physical control to an action.
• Action Map: groups related actions.
• Control Scheme: groups devices for a control setup.

Typical structure:

Player
├── Move
├── Look
├── Jump
├── Attack
└── Interact

Namespace:

using UnityEngine.InputSystem;
