The exit feature is an important element that provides convenience to users while developing games. There are various ways to exit a game, and we will explore different implementation techniques for this. In this tutorial, we will discuss how to implement the exit feature using the Unity engine, as well as several ways to enhance user experience. Finally, we will provide the necessary code and a step-by-step guide to implement this feature.
1. Importance of the Exit Feature
The exit feature is a very important element in games or applications. Users should be able to exit the game at any time, providing a convenient user experience. The main objectives are as follows:
- Providing a Convenient User Experience: It is important to allow users to easily exit when they want to stop playing the game.
- Resource Management: Since the game consumes system resources while it is running, it should be appropriately exited when needed.
- Data Saving: The exit feature can be connected to saving the game progress and allowing it to be restarted later.
2. Basic Implementation of the Exit Feature
2.1. Setting Up the Unity Project
To implement the exit feature, you first need to set up a Unity project. Follow the steps below to create the project:
- Open Unity Hub and create a new 2D or 3D project.
- Enter a project name and set the save path.
- After creating the project, open the default scene to prepare to add a UI.
2.2. Adding the UI
You need to create a button for exiting the game. Follow these steps to add the button:
- Right-click in the Hierarchy panel and select
UI > Buttonto add a button. - Once the button is added to the Hierarchy, select the
Buttonobject and change the button text to “Exit” in theInspectorwindow. - Adjust the button’s position and size to design it as desired.
2.3. Adding the Script
Now you need to add a script that will exit the game when the button is clicked. Follow the steps below:
- Right-click in the Project panel, select
Create > C# Scriptand name the scriptExitGame.cs. - Add the following code to the
ExitGame.csfile:
using UnityEngine;
public class ExitGame : MonoBehaviour
{
public void QuitGame()
{
// Request to exit the game
Application.Quit();
// When testing in the editor
#if UNITY_EDITOR
UnityEditor.EditorApplication.isPlaying = false;
#endif
}
}
2.4. Connecting the Button to the Script
Now connect the button to call the QuitGame function when clicked:
- Select the button in the Hierarchy.
- Find the
Button (Script)component in theInspectorwindow. - In the
On Click()section, click the+button to add a new event. - Drag and drop the
ExitGamescript onto the button game object. - Select
ExitGame > QuitGame()from the dropdown menu.
3. Enhancing User Experience
In addition to the basic exit feature, it is advisable to confirm with the user before exiting the game. This can prevent accidental exits. Below are the steps to add a confirmation dialog:
3.1. Creating a Confirmation Popup UI
To create a confirmation popup, add a UI > Panel and add text and two buttons (e.g., “Yes” and “No”) inside it. You will also need a script to handle user clicks.
3.2. Writing the Confirmation Script
Write a script for the confirmation popup to activate it and handle the exit process:
using UnityEngine;
using UnityEngine.UI;
public class ExitGameConfirmation : MonoBehaviour
{
public GameObject confirmationPanel;
public void ShowConfirmation()
{
confirmationPanel.SetActive(true);
}
public void QuitGame()
{
Application.Quit();
#if UNITY_EDITOR
UnityEditor.EditorApplication.isPlaying = false;
#endif
}
public void CancelQuit()
{
confirmationPanel.SetActive(false);
}
}
4. Final Check and Testing
After completing all tasks, you need to test to ensure the functionality works correctly. Check if the exit confirmation panel appears when you click the UIButton, and confirm that the game exits when you click “Yes” there.
5. Conclusion
Now you understand how the exit feature works in Unity. Although the exit function is simple, it can have a substantial impact on user experience.
