First Unity project (Hello World scene) - Mini Project: Build & Apply

First Unity project (Hello World scene)

📖 Scenario: You are creating your first Unity project to display a simple "Hello World" message in a 3D scene. This is like putting up a sign in a park that says "Hello World" for everyone to see.

🎯 Goal: Build a Unity scene that shows a 3D text object with the exact message "Hello World" visible in the game view.

📋 What You'll Learn

Create a new Unity scene with a 3D Text object

Set the text content to "Hello World"

Position the text so it is visible in the main camera view

Add a simple script to control the text if needed

💡 Why This Matters

🌍 Real World

Creating simple 3D text displays is common in games and interactive apps to show messages, instructions, or titles.

💼 Career

Understanding how to set up scenes, add objects, and write scripts is foundational for Unity developers building interactive experiences.

1

Create a new Unity scene and add a 3D Text object

In your Unity project, create a new scene. Then add a 3D Text object named helloText to the scene hierarchy.

Unity

// Create a new scene and add a 3D Text object named helloText
// Your code here

Need a hint?

Use the Unity Editor menus to create a new scene and add a TextMeshPro 3D text object. Rename it exactly to helloText.

2

Set the text content to "Hello World"

Select the helloText object and set its text content property to the exact string "Hello World".

Unity

// Select helloText and set its text property to "Hello World"
// Your code here

Need a hint?

Look in the Inspector panel for the helloText object. Find the Text field and type exactly "Hello World".

3

Position the text so it is visible in the main camera view

Set the helloText object's position to (0, 0, 5) so it appears in front of the main camera at (0, 0, 0).

Unity

// Set helloText position to (0, 0, 5) in the Transform component
// Your code here

Need a hint?

In the Transform component of helloText, set the X and Y to 0 and Z to 5 so the text is in front of the camera.

4

Add a simple script to rotate the text slowly

Create a new C# script named HelloWorldRotator and attach it to helloText. In the script, write code to rotate the text around the Y-axis by 20 degrees per second.

Unity

// Create HelloWorldRotator.cs script and attach to helloText
// Add code to rotate around Y-axis by 20 degrees per second
// Your code here

Need a hint?

Create a new C# script file named HelloWorldRotator.cs. Use the Update() method to rotate the object smoothly every frame.
