Unity is a popular free-to-use game engine used to create games for all kinds of platforms, like PC, mobile, and even VR. Even if you’re a complete beginner, Unity is the perfect platform to start your game development journey. Again, it’s the gaming engine that is highly known for some of the world’s most popular games, like Angry Bird, and Pokemon Go. And the best part is, you’ll have everything you need to bring your ideas to life with Unity, no matter your experience level.
In this guide, we’ll cover everything you need to know to make your first game in Unity. From setting up your game project to adding animations and even exporting games for your device, all in a step-by-step guide.
Step 1: Install Unity Hub and Create Your Project
1. Download and install Unity Hub:
To download Unity Hub, go to the Unity website and download Unity Hub. Unity Hub is a launcher that manages your Unity versions, projects, and other settings. After downloading, simply install it on your computer.

You’ll have individual downloading options for Windows and Mac. So, download Unity according to your device.
2. Create a Unity Account ID

If you don’t already have one, create a Unity account. With this account, you can access all Unity services like the Asset Store, online collaboration, and cloud saves. To create a free account in Unity, just open the Unity Hub and sign in with your email ID.
3. Install Unity Editor and Visual Studio

Now, inside the Unity Hub, click on the “Installs” tab and install the Unity Editor. Choose the version according to your device compatibility or a recent stable version.

Unity will prompt you to install Microsoft Visual Studio, which is essential for writing code. During installation, select “Game Development with Unity” as the workload to install all necessary tools.
4. Create a New Project

Once Unity is successfully installed, click on the “New Project” button in Unity Hub. Since here, we are planning to create a 2D game. So, go to the Core tab, and simply choose the “2D” option. Name your project based on your Unity game type and hit the “Create” button to start your game development process.
Step 2: Create Game Objects and Its Components in Unity
Now that your project is set up, let’s start building the core elements of your game. Unity provides a variety of tools to create and manage these elements. Here’s how you can create the basic game objects for your scene:
1. Create Game Objects
In Unity, everything in your game (characters, obstacles, backgrounds, etc.) is a game object. Here’s how you can create and add them to your scene:
- Create an empty game object:
To create a Unity game object, go to the Hierarchy Panel and select Create Empty. This creates a blank game object, which you can name according to its role. For example: Player, Obstacle, Background, etc.
An empty game object doesn’t have any visual representation, but it can serve as a container for other elements (like adding a character’s movement script or holding various child objects like obstacles).
- Create 2D Sprites:
For 2D sprite creation, you’ve to right-click in the Hierarchy Panel, choose 2D Object, and then select Sprite. This creates a new 2D object with a default sprite, but you can replace the default sprite with othe ne you import. The sprite could represent a character, obstacle, or any other object in your game.
You can drag the desired sprite image from your assets into the Sprite field in the Inspector Panel to assign it to the newly created object.
- Create UI Elements (Optional for interface):
To create UI elements in Unity, right-click in the Hierarchy Panel and choose UI > Text for displaying text. Again, go to UI > Button for interactive elements like start buttons. You can use these elements to create a game interface, such as displaying score, and health, or providing a start screen.
- For Multiplayer Unity Game
If you want to make a multiplayer game in Unity, you can use Unity’s Multiplayer Networking tools like Mirror or Photon. Then, just set up networked objects, synchronize player actions, and manage connections between players over the internet.
2. Position and Transform Game Elements
After creating your game objects, you need to place them accordingly in your scene.
- Positioning Unity Game Objects:

To place the game objects in Unity, go to the Hierarchy Panel and select the game object.Then, use the Move Tool (shortcut: W) to drag the object to a new position in the Scene View. You can also adjust the object’s position numerically by changing the Transform values in the Inspector Panel.
- Scaling and rotating objects:
Now, to scale the elements, select the game object and use the Scale Tool (shortcut: R) to resize it. You can scale uniformly or along specific axes.

In the Inspector Panel, you can also input specific scale values for X, Y, and Z axes. And, to rotate an object, select it and use the Rotate Tool (shortcut: E) to rotate the object in 2D or 3D space.
3. Add Components to Your Game Objects
To make your game objects behave in specific ways, you need to add components to them. These components define an object’s behaviour or appearance. Here are some common components you can add to game objects:
- Sprite Renderer:
If you’re working with 2D sprites, add a Sprite Renderer component to make the sprite visible in the scene. This will display the sprite image you’ve assigned to the object.

To add a sprite renderer, go to the Inspector Panel, click Add Component, and type “Sprite Renderer” in the search box to add it.
- Rigidbody 2D (Physics):
To give your game object physics properties like gravity or velocity, add a Rigidbody 2D component. This allows your object to interact with other physics objects in the game.

For this, go to the Inspector Panel, click Add Component, and select Rigidbody 2D.
- Colliders (For Interaction):
To detect collisions between objects (like a bird hitting a pipe or an enemy), you need to add a Collider 2D component. This will define the boundaries of your object for detecting interactions.

For a basic 2D object, you can add a Box Collider 2D or Circle Collider 2D, depending on your object’s shape. To add, simply select the game object, go to the Inspector, and click Add Component > Box Collider 2D or Circle Collider 2D.
4. Grouping Objects (Optional)
Sometimes, you’ve to group the game objects to manage them more efficiently based on your game demand such as,
- Create Parent-Child Relationships:
For example, you might create an empty object as the parent and place your character and related elements (like a shadow) as child objects. This way, when you move the parent, all child objects will move together. Simply drag one object in the Hierarchy Panel onto another to create a parent-child relationship.
Step 3: Add Physics and Colliders to the Game
You have all your game objects ready, but how do they interact with each other? This is where physics and colliders come in.
In Unity games, these physics let your game elements create realistic interactions, detect collisions, respond to gravity, and even enable dynamic movements to make your gameplay engaging and immersive.
Add Rigidbody 2D Components
For example, to make your Unity game bird react to physics (like gravity), you need to add a Rigidbody 2D component. Just select the Bird object again, go to Add Component, and choose Rigidbody 2D. This will make the Bird a physics object that will fall when the game starts.
Add a Collider
To define the physical boundaries of your Bird and detect collisions, add a Circle Collider 2D. This will ensure that the bird in your game can interact with other objects, like the pipes. You may need to adjust the size or position of the collider to ensure it fits the sprite properly.
You can also use colliders to detect when the bird hits an obstacle like a pipe. If a collision occurs, you can trigger a game over state, such as stopping the game or displaying a game over screen.
Step 4: Write Your First Unity Script with C#
To make your game interactive and control how objects behave and respond, scripting in Unity is essential. Unity scripting is free and primarily uses C# (known as C-sharp), and it’s similar to Java and the C++ language. Additionally, many other .NET languages can be used with Unity if they compile compatible DLLs.
1. Add new script with C#
To create a new script in Unity, open your Project >> Assets folder. Then, right-click inside the folder, select Create > C# Script, and name your script. Now, simply double-click it to open in your code editor (such as Visual Studio). After writing your code, save it, then drag the script onto your GameObject in the scene to attach it.
Example Code: You can write a small script that will change the name of the Bird object when the game starts. Here’s an example of code you could use:
void Start() {
gameObject.name = “Flappy Bird”;
}
This code changes the name of the Bird object to “Flappy Bird” when the game starts.
2. Open the Script in Visual Studio
To open a script in Visual Studio, simply double-click the script file in Unity’s Project window, where you can write the game logic. Unity will automatically open the file in Visual Studio, where you can edit the code. The script has two key methods:
- Start(): Runs once when the object is initialized.
- Update(): Runs continuously during each frame of the game.
Let’s have an example of gravity and jumping logic.
Now you want the Bird to be able to jump when the player presses the spacebar. In the Update() method, add the following code:
void Update() {
if (Input.GetKeyDown(KeyCode.Space)) {
GetComponent<Rigidbody2D>().velocity = new Vector2(0, 5);
}
}
This code checks for a key press (spacebar) and applies an upward force to the bird. After adding the script, click the Play button in Unity to test the Bird’s movement. If everything works, the Bird should fall and jump whenever you press the spacebar.
Step 5: Customizing Your Game’s Look and User Experience
After writing your Unity script, you can customize your game’s look and user experience to make it look great and fun to play. Unity has simple tools to help you do this quickly and easily.
For example, if you want to change how objects look, go to the Inspector panel. Just click on an object in your scene, and you can change its color, texture, or material. Unity’s Material Editor also lets you adjust things like how reflective or see-through the object is.
To add things like buttons, menus, or score counters, use Unity’s Canvas system. This tool lets you drag and drop UI elements directly onto your screen.
For example, you can add a play button to start the game or a health bar that updates during gameplay. You can move these elements around, change their size, and even style them with different colors and fonts.
If you want to set the mood of your game, use the Unity lighting and camera settings. In the Lighting tab, you can make your game feel bright and cheerful or dark and mysterious. Again, to adjust the camera view, go to the Inspector tab>> Camera to give your players the best angle for gameplay.
Step 6: Add Animations and Sound Effects
Your game is almost ready. However, to make the game fun, import animations (like birds flapping) and sound effects (jumping or background music). Attach these to the appropriate game objects using the Animator and Audio Source components.
Add Animation to your Game
To create animations in Unity, open the Animation tab, select an object, and click Create to save a new animation clip. Use the Record button to move or transform the object over time.
For example, you can make a character wave or a ball bounce. Once done, stop recording and attach the animation to the object using the Animator Controller.
Add Sound Effect in Unity
To add sound in Unity, first, import your sound file into the Assets folder. Select the object you want to use and add an AudioSource from the Inspector to enter your sound. You can play it automatically or control it through your script.
Step 7: Export Your Game through Unity
Once your game is complete, you are ready to publish your game.
But, before you export your Unity game, first playtest it within Unity to check for any issues and ensure everything is working as expected.
Once you’re ready to publish the game you made in Unity, go to File > Build Settings and choose your target platform, whether it’s PC, Mac, Android, iOS, or others.
If necessary, install the required modules via Unity Hub. You can then adjust the quality settings and make any platform-specific changes like screen resolution or input methods.
After configuring these settings, click Build and select the location to save the build. Unity will compile the game for the selected platform with the necessary files for you to share, install, or distribute without any hassle.
