The variables you created are private and they were not assigned to any value. For simplicity purposes, you can change them to public. I assume your scripts are assigned to gameobjects, If you click on any of your gameobjects in the hierarchy you will see your attached script, and underneath you will see the gameobjects that script expects. Then you can drag and drop the gameobjects you wanna use in that script.

Simply add the word “public” before the definitions of gameBall and scoreText, like so:

public BallScript gameBall;
public Text scoreText;
