Triggering even based on score

New to Unity3d and wanted to know how I go about starting an event or cutscene once a player reaches a certain score in a space shooter game. So let's say they get to a score of 50,000 and I want to trigger a cutscene then boss fight. How or what is the scripting I am looking for. Thank you in advance!!!!

 

Oversimplified example:

Code (csharp):

1. private int score = 0;  //The current score
2. private int scoreToTriggerBossFight = 50000;  //The score which triggers a boss fight
3.  
4. //Call this to add to the score, such as when you defeat an enemy
5. public void AddToScore(int addToScore)
6. {
7.   score += addToScore;
8. }
9.  
10. //Return the current score
11. //Can also use a getter, or make score public
12. //But doing it this way better protects than a public variable
13. //and is usually easier to understand for a novice
14. public int GetCurrentScore()
15. {
16.     return score;
17. }
18.  
19. //Check if the score reaches the level which should trigger the boss fight every frame
20. //You could do this check instead in AddToScore, but is cleaner here if you have other things
21. //which change the score other than AddToScore, such as subtracting from score, etc
22. private void Update()
23. {
24.     if (score >= scoreToTriggerBossFight)
25.     {
26.         startBossFight();
27.     }
28. }
29.  
30. //Call this to kick off a boss fight
31. private void startBossFight()
32. {
33.     //Add whatever code here to start your boss fight
34.     //I'll just assume though that you do so by switching to the BossFight scene
35.     SceneManagement.SceneManager.LoadScene("BossFight");
36. }

 

Hey, cannot thank you enough. I really appreciate it!
