Hello! In this tutorial, we will explore how to create an ending screen after making a game in Unity and implement the exit functionality. This tutorial is aimed at those with a basic understanding of Unity and will proceed step by step. Each step will include necessary code examples and explanations.

1. Course Overview

This course consists of two main parts:

• Creating an ending screen
• Implementing the exit functionality

Each part will show how to utilize Unity’s user interface (UI) to enhance the game’s experience. Through this tutorial, you will learn to add an ending screen to your game and provide a way for users to easily and conveniently exit the game.

2. The Need for an Ending Screen

Providing an appropriate ending screen to players after the game ends is an important part of the gaming experience. Through the ending screen, players can review their achievements in the game and choose an option to restart. A good ending screen helps leave a positive impression on players even after they have finished the game.

3. Creating the Ending Screen

3.1 Setting Up the Project

First, open Unity and create a new 2D project. Let’s name the project ‘EndingScreenExample’.

3.2 Setting Up the UI

To create the ending screen, we need to set up the UI. Follow these steps:

1. Select GameObject > UI > Canvas in the Unity editor to add a canvas.
2. Add UI > Panel inside the canvas to create a background panel.
3. Adjust the size of the panel to cover the entire screen.
4. Add UI > Text inside the panel to enter the ending message. For example: “You have completed the game!”
5. Add UI > Button to create a ‘Return to Main Menu’ button.
6. Change the button text to ‘Restart’ or ‘Main Menu’ in the properties.
7. Additionally, add background music or sound effects to make the ending screen more interesting.

3.3 Writing the Script

Now, let’s write a C# script to implement the functionality of the ending screen. Create a script like the following:

using UnityEngine;
    using UnityEngine.SceneManagement;
    using UnityEngine.UI;

    public class EndingScreen : MonoBehaviour
    {
        public GameObject endingPanel;

        public void ShowEndingScreen()
        {
            endingPanel.SetActive(true);
        }

        public void RestartGame()
        {
            SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
        }

        public void QuitGame()
        {
            Application.Quit();
        }
    }
    

In the above script, the ShowEndingScreen method shows the ending screen, and the RestartGame and QuitGame methods handle restarting or quitting the game when each button is clicked.

3.4 Connecting Functions to Buttons

Connect the script to the buttons so that the functions are triggered when they are clicked. After selecting the button, add the On Click() event in the inspector and connect it to the RestartGame and QuitGame methods of the EndingScreen script.

4. Implementing the Exit Functionality

Now let’s add a feature that allows users to easily exit the room when they want to quit the game. This function primarily operates through button clicks and can be implemented through the steps below.

4.1 Adding a UI Button

Add a UI > Button to the main menu or ending screen of the game. Set the button text to ‘Exit Room’.

4.2 Writing the Exit Script

Write a new script to implement the exit functionality. Refer to the example below:

using UnityEngine;

    public class ExitGame : MonoBehaviour
    {
        public void ExitRoom()
        {
            Application.Quit();
            #if UNITY_EDITOR
            UnityEditor.EditorApplication.isPlaying = false;
            #endif
        }
    }
    

The above code provides the functionality to exit the game when leaving the room and also handles testing in editor mode.

4.3 Connecting the Exit Functionality to the Button

Connect the ExitGame script to the button to activate the functionality of exiting when clicked. Select the button and set the On Click() event in the inspector to connect with the ExitRoom method of the ExitGame script.

5. Comprehensive Testing

Once all setups are complete, run the game to test if the functionality works correctly. Check if the ending screen appears and if each function operates upon button clicks. If everything works well, you have successfully implemented the ending screen and exit functionality in Unity!

6. Conclusion and Tips

Through this tutorial, you have learned how to implement a simple ending screen and exit functionality in Unity. Consider the following:

• Enhance UI design by adding animation effects.
• You can display various ending messages based on the game result.
• Consider adding features to record and display the player’s score or achievements.

This concludes the Unity basics tutorial on creating an ending screen and exit functionality. I hope it helps you in your game development journey!

Hello! In this tutorial, we will learn in detail how to create an enemy character that chases the player character using Unity.

• 5. Testing and Optimization
• 6. Conclusion

1. Installing Unity and Setting Up the Project

First, let’s install Unity and create a new 3D project. Please download and install Unity Hub from the official Unity website, then follow these steps.

1. Run Unity Hub and click the New Project button.
2. Enter a name for the project, select the 3D template, and then click the Create button.
3. Once the project is created, the basic scene environment will appear.

2. Creating the Player Character

To create the player character, we will use basic 3D objects. We will proceed with the following steps.

1. Right-click in the Hierarchy window and select 3D Object > Capsule. We will use this as the player character.
2. Adjust the Transform component of the Capsule to set an appropriate size.
3. In the Inspector window, click the Add Component button and add a Rigidbody to apply gravity.
4. Also, set the character to touch the ground using a Collider.

3. Creating the Enemy Character

Now let’s add the enemy character. The enemy character can also be created using a 3D object.

1. Right-click in the Hierarchy window again and select 3D Object > Cube to create the enemy character.
2. Adjust the Transform component of the Cube to set the size and position of the enemy character.
3. Add a Rigidbody component to the enemy to enable physical interactions.

4. Writing the Tracking Script for the Enemy Character

Now let’s write a script to allow the enemy character to track the player. Here’s an example of a C# script.

using UnityEngine;

public class EnemyController : MonoBehaviour
{
    public Transform player; // Player's Transform
    public float speed = 2.0f; // Speed of the enemy character
    public float detectionRange = 5.0f; // Range within which the enemy can chase

    void Update()
    {
        // Calculate distance to the player
        float distance = Vector3.Distance(transform.position, player.position);
        
        // Move towards the player if within range
        if (distance < detectionRange)
        {
            Vector3 direction = (player.position - transform.position).normalized;
            transform.position += direction * speed * Time.deltaTime;
        }
    }
}

Using the code above, set up the enemy character to chase the player. Attach the script to the enemy character object and drag the player character into the player field to add it.

5. Testing and Optimization

Now that everything is set up, run the game in play mode to check if the enemy character chases the player properly.

You should also consider performance optimization. As the number of enemies increases, avoid simply having all enemies chase the player; consider additional logic to limit the number of enemies that chase.

6. Conclusion

In this tutorial, we learned how to implement an enemy character that chases the player character using Unity. In this process, we created basic 3D objects and wrote scripts to implement game AI. These fundamental elements will serve as a basis for creating more complex game logic.

Unity is a widely used engine for game development, supporting many features for creating interactive content. Since games provide various outcomes based on player actions, conditional statements play a very important role in game logic. In this tutorial, we will take a closer look at one of the conditional statements, ‘else if’.

1. Basic Concept of Conditional Statements

A conditional statement allows a program to perform different actions based on certain conditions. The ‘if’ statement evaluates a condition and executes specific code when the condition is true. The ‘else’ statement defines the code that will be executed if the condition is false. The ‘else if’ statement provides a way to evaluate multiple conditions sequentially.

2. Basic Syntax

The basic syntax for using a conditional statement is as follows:

if (condition) {
    // Code to execute if the condition is true
} else if (condition2) {
    // Code to execute if condition2 is true
} else {
    // Code to execute if all previous conditions are false
}
    

Here, ‘condition’ is a variable or calculated expression that determines whether it is true (when it has a true value) or false (when it has a false value).

3. Example of Using ‘else if’

Let’s look at an example of handling more complex conditions using ‘else if’. The example below implements an NPC that reacts based on the player’s health.

Example Code

using UnityEngine;

public class PlayerHealth : MonoBehaviour {
    public int playerHealth = 100;

    void Update() {
        if (playerHealth > 75) {
            Debug.Log("The player is healthy.");
        } else if (playerHealth > 50) {
            Debug.Log("The player is slightly injured.");
        } else if (playerHealth > 25) {
            Debug.Log("The player is seriously injured.");
        } else {
            Debug.Log("The player is in critical condition!");
        }
    }
}
    

The above code outputs an appropriate message based on the player’s health every frame. It allows handling multiple states clearly by separating conditions.

4. Applications of Conditional Statements

Conditional statements are useful in various cases:

• Game State Management: Different logic can be executed based on the game’s progress. For instance, checking whether the player has won or lost.
• AI Behavior Control: NPCs can be programmed to respond differently based on the player’s actions.
• UI Response: UI elements can be changed based on user input.

5. Comparison of ‘else if’ and switch Statements

Another method to evaluate conditions besides the ‘else if’ statement is the ‘switch’ statement. The switch statement allows handling multiple conditions based on the value of a specific variable. Let’s consider a simple example.

int score = 85;

switch (score) {
    case 90:
        Debug.Log("A");
        break;
    case 80:
        Debug.Log("B");
        break;
    case 70:
        Debug.Log("C");
        break;
    default:
        Debug.Log("Not applicable");
        break;
}
    

In this example, different messages are output based on the value of the ‘score’ variable. Unlike the ‘else if’ statement, the switch statement can express handling specific values more concisely.

6. Performance of Conditional Statements

Having many conditional statements can impact performance. Particularly when using ‘else if’, the order of conditions is important. It is advisable to place the conditions that are most frequently executed at the top. Reducing unnecessary condition evaluations can help optimize performance.

7. Conclusion

Through this tutorial, we have increased our understanding of conditional statements in Unity, especially the ‘else if’ statement. In game development, conditional statements are essential for reflecting player actions and handling various game situations. By setting various conditions and implementing appropriate logic, you can create more dynamic games.

In this course, we will learn how to implement the feature of creating a simple network room using the Unity engine. Unity is a widely used platform for game development, and the latest networking framework has made multiplayer game development easier than ever. This tutorial will cover the basics of using Unity and its networking features while explaining how to create and manage a simple multiplayer room.

1. Project Setup

Before starting with Unity, you need to set up a project. Follow the steps below:

1. Run Unity Hub and create a new project.
2. Select ‘3D’ as the template and appropriately name your project.
3. Click the ‘Create’ button to create the project.

After creating the project, set up a basic scene through the Unity editor. Right-click in the Hierarchy window to add a new GameObject and select Terrain to create the basic terrain.

2. Installing the Networking Package

The basic networking functionality of Unity can be installed through the Unity Package Manager. Follow the steps below to install the package:

1. Select Window > Package Manager.
2. Click the plus (+) button and select ‘Add package from Git URL’.
3. Enter the following URL to add the ‘Mirror’ package:

https://github.com/vis2k/Mirror.git

Mirror is an open-source networking library for use with Unity. This package allows you to implement multiplayer games.

3. Setting up the Network Manager

To create a network room, you need to set up the NetworkManager. The NetworkManager is a crucial component that manages all network activities. Follow the steps below to set it up:

1. Create an empty GameObject in the Hierarchy and rename it to ‘NetworkManager’.
2. Add the ‘NetworkManager’ component to this GameObject.
3. Also, add the ‘NetworkManagerHUD’ component to create a basic UI.

Now you are ready to set up the network room. NetworkManagerHUD provides a basic UI to create a host or connect a client.

4. Creating and Connecting to a Room

We will add functionalities to create and connect to a room within the game. You will need to write scripts for this. Follow the steps below:

4.1 Creating a Room Creation Script

1. Create a Scripts folder in the Project window and create a ‘RoomManager.cs’ file inside it.
2. Implement the room creation functionality by entering the following code:

using UnityEngine;
using Mirror;

public class RoomManager : NetworkManager
{
    public override void OnStartServer()
    {
        Debug.Log("Server starting");
    }
    
    public override void OnStartClient()
    {
        Debug.Log("Client connected");
    }

    public void CreateRoom()
    {
        NetworkServer.Listen(7777);
        Debug.Log("Room created");
    }

    public void JoinRoom()
    {
        NetworkClient.Connect("127.0.0.1", 7777);
        Debug.Log("Connecting to room...");
    }
}

4.2 Connecting the UI and Script

1. Connect the ‘CreateRoom’ method to be called when the ‘OnHostButton’ of NetworkManagerHUD is clicked.
2. Set it up so that the ‘JoinRoom’ method is called when the ‘OnClientButton’ is clicked.

5. Setting up Player Prefab

When a player enters a room, you need to set what object will be instantiated. Here’s how to set up the player prefab:

1. Create a new GameObject and name it ‘Player’.
2. Add a ‘NetworkIdentity’ component to this GameObject and check ‘Local Player Authority’.
3. Make this GameObject a Prefab and save it in the Resources folder.
4. Add the following code to the RoomManager script to set the player prefab:

public GameObject playerPrefab;

    public override GameObject OnStartPlayer(NetworkConnection conn)
    {
        return Instantiate(playerPrefab);
    }

6. Testing and Debugging

Now that all the settings are complete, it’s time to run a test. Check if the network room creation and client connection work properly:

1. Click the ‘Play’ button in the Unity editor to start the server.
2. Run a new instance of Unity editor to connect the client.
3. Check the console logs of both server and client to verify the connection status.

7. Conclusion

You have now implemented the basic functionalities of creating and connecting to a simple network room. Through this, you have gained an understanding of the fundamentals of multiplayer game development, and learned the necessary steps to add more complex networking features in the future.

Based on what you learned from this course, you can expand on it by implementing features such as:
