Learn to add the new Input System package to the project.
Why the new Input System exists
The old Input class is enough for small games but falls short for games that need multiple devices such as gamepad and touch. The new Input System package lets you define input independently of the device and is installed from Window > Package Manager > Unity Registry.
using UnityEngine.InputSystem;
if (Keyboard.current.spaceKey.isPressed)
{
Debug.Log("Bosluk basildi");
}After the install you reach devices directly through the Keyboard, Gamepad and Mouse classes.
Enabling it after installation
When the package is installed Unity offers to switch the active input handling and restarts the editor. The same choice lives under Edit > Project Settings > Player > Active Input Handling. The options are Input Manager (Old), Input System Package (New) and Both; Both means both systems run at the same time.
using UnityEngine.InputSystem;
if (Gamepad.current != null)
{
Debug.Log("Gamepad bagli");
}Practice Compute the active input handling
Write a MonoBehaviour named GirdiAyari. Add two bool fields called eskiKullan and yeniKullan and set both to true. In Start handle three cases: if both are true assign Both, if only yeniKullan is true assign Input System Package (New), otherwise assign Input Manager (Old) to the ayar variable. Finally call Debug.Log(ayar).
Starter code
using UnityEngine;
public class GirdiAyari : MonoBehaviour
{
bool eskiKullan = true;
bool yeniKullan = true;
void Start()
{
string ayar = "";
// eskiKullan ve yeniKullan degerlerine gore uc durumu ele al
// iki deger de true ise birlesik secenegi ata
// yalnizca yeniKullan true ise yeni paket secenegi ata
// diger durumda eski yonetici secenegi ata
Debug.Log(ayar);
}
}Sample solution
using UnityEngine;
public class GirdiAyari : MonoBehaviour
{
bool eskiKullan = true;
bool yeniKullan = true;
void Start()
{
string ayar;
if (eskiKullan && yeniKullan)
{
ayar = "Both";
}
else if (yeniKullan)
{
ayar = "Input System Package (New)";
}
else
{
ayar = "Input Manager (Old)";
}
Debug.Log(ayar);
}
}Expected output
Both
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 Where is the new Input System package installed from?
- It is installed from the Package Manager, Unity Registry list Correct answer
- It is enabled under Player Settings > Quality
- It is downloaded from the Asset Store
- It is added from the Build Settings window
Explanation: The Input System is an official Unity package; select Input System under Window > Package Manager > Unity Registry and press the Install button.
2 Complete the active input handling value
string ayar = "____";string ayar = "Both";Explanation: When old and new input run together the Active Input Handling value is Both; the single-system values do not cover that case.
