How do i change this line so that it works as im getting the error Assets/BoxLauncher.cs(28,53): error CS0246: The type or namespace name `ScoreManager' could not be found. Are you missing a using directive or an assembly reference?

Assets/BoxLauncher.cs(28,53): error CS0246: The type or namespace name `ScoreManager’ could not be found. Are you missing a using directive or an assembly reference? And also “score” is red

GameObject.FindObjectOfType().score++;

Without seeing your code it’s a bit harder so try this :

ScoreManager something = GameObject.FindObjectOfType(typeof(ScoreManager)) as ScoreManager;
		something.score++;
