💡 Why This Matters

🌍 Real World

Saving player progress or settings in games so they are remembered between sessions.

💼 Career

Game developers often use PlayerPrefs or similar systems to store simple data like scores, settings, or preferences.

1

Create a high score variable

Create an integer variable called highScore and set it to 100.

Unity

# Your code here

Need a hint?

Use int to create a number variable and set it to 100.

2

Create a key for PlayerPrefs

Create a string variable called highScoreKey and set it to "HighScore".

Unity

int highScore = 100;
# Your code here

Need a hint?

Use string to create a text variable for the PlayerPrefs key.

3

Save the high score using PlayerPrefs

Use PlayerPrefs.SetInt with highScoreKey and highScore to save the score.

Unity

int highScore = 100;
string highScoreKey = "HighScore";
# Your code here

Need a hint?

Use PlayerPrefs.SetInt(key, value) to save an integer.

4

Load and print the high score

Use PlayerPrefs.GetInt with highScoreKey to load the score into loadedScore. Then print loadedScore using Debug.Log.

Unity

int highScore = 100;
string highScoreKey = "HighScore";
PlayerPrefs.SetInt(highScoreKey, highScore);
# Your code here

Need a hint?

Use PlayerPrefs.GetInt(key) to load the saved integer. Use Debug.Log(value) to print it.
