Sprite creation and import in Unity - Mini Project: Build & Apply

Sprite creation and import

📖 Scenario: You are making a simple 2D game in Unity. You want to add a character image to your game scene. This image is called a sprite.

🎯 Goal: You will create a sprite asset and import it into your Unity project. Then you will add it to the scene so it appears when you run the game.

💡 Why This Matters

🌍 Real World

Sprites are the basic images used in 2D games to represent characters, objects, and backgrounds.

💼 Career

Knowing how to create and import sprites is essential for game developers working with Unity to build 2D games.

1

Create a sprite asset

Create a new sprite asset in your Unity project called characterSprite. Use a simple square image of size 100x100 pixels with a solid color.

Unity

# Create a sprite asset named characterSprite
# Your code here

Need a hint?

Use an image editor to create a 100x100 pixel PNG with a solid color. Then drag it into Unity's Assets folder. Select it and set Texture Type to Sprite (2D and UI).

2

Import the sprite into the project

In your Unity project, import the sprite asset characterSprite so it is ready to use in the scene. Confirm the sprite is visible in the Assets folder.

Unity

// In Unity Editor, create a new 2D sprite asset named characterSprite
// This is done by importing a 100x100 solid color PNG image and setting its Texture Type to Sprite (2D and UI)
// Import the sprite asset into the project
# Your code here

Need a hint?

Drag the image file into the Assets folder in Unity. Check the Inspector to confirm it is set as a Sprite.

3

Add the sprite to the scene

Create a new GameObject in the scene called characterObject. Add a SpriteRenderer component to it and assign the characterSprite to the SpriteRenderer's sprite property.

Unity

// In Unity Editor, create a new 2D sprite asset named characterSprite
// This is done by importing a 100x100 solid color PNG image and setting its Texture Type to Sprite (2D and UI)
// The sprite asset characterSprite is now imported and visible in the Assets folder

// Create a GameObject named characterObject and add a SpriteRenderer with characterSprite
# Your code here

Need a hint?

Use new GameObject("characterObject") to create the object. Then add a SpriteRenderer component and set its sprite to characterSprite.

4

Display the sprite in the game view

Write a print statement to confirm the sprite is assigned by printing characterObject's SpriteRenderer sprite name. Run the game to see the sprite appear in the scene view.

Unity

using UnityEngine;

public class SpriteSetup : MonoBehaviour
{
    public Sprite characterSprite;

    void Start()
    {
        GameObject characterObject = new GameObject("characterObject");
        SpriteRenderer renderer = characterObject.AddComponent();
        renderer.sprite = characterSprite;

        // Print the sprite name to confirm assignment
        # Your code here
    }
}

Need a hint?

Use print("Sprite assigned: " + renderer.sprite.name) inside the Start method.
