Help with scoreboards ( java)

[NUJABES__]

Hello. I am new to java, and do not possess any extensive knowledge to the programming language. I have a scoreboard that displays this upon the PlayerJoinEvent activating.

It displays something like this

Your stats
Pearls: 0
Blocks: 0

This scoreboard updates the amount of blocks you have broken and the amount of enderpearls you have thrown each time you break/throw one. The block break event works fine, but i cannot get the playerinteractevent to update the enderpearls each time you throw it.
Here's my code

1. public class SecondPlugin extends JavaPlugin implements Listener {
2. 
   
3. @Override
4. public void onEnable() {
5. System.out.println("OnEnable has been called.");
6. getServer().getPluginManager().registerEvents(this, this);
7. }
8. 
   
9. @Override
10. public void onDisable() {
11. System.out.println("OnDisable has been called.");
12. }
13. 
    
14. @EventHandler (priority = EventPriority.NORMAL)
15. public void onPlayerJoin(PlayerJoinEvent e) {
16. 
    
17. //scoreboard
18. Scoreboard board = getServer().getScoreboardManager().getNewScoreboard();
19. Objective objective = board.registerNewObjective("blocks","pearl");
20. objective.setDisplaySlot(DisplaySlot.SIDEBAR);
21. objective.setDisplayName(ChatColor.GREEN + "Your stats");
22. Score score = objective.getScore(ChatColor.AQUA+"Blocks:");
23. Score score1 = objective.getScore(ChatColor.AQUA+"Pearls:");
24. 
    
25. 
    
26. 
    
27. 
    
28. score.setScore(0);
29. score1.setScore(0);
30. e.getPlayer().setScoreboard(board);
31. 
    
32. 
    
33. 
    
34. }
35. @EventHandler
36. public void onBreak(BlockBreakEvent e) {
37. Scoreboard board = e.getPlayer().getScoreboard();
38. Objective objective = board.getObjective("blocks");
39. objective.getScore(ChatColor.AQUA + "Blocks:").setScore(objective.getScore(ChatColor.AQUA + "Blocks:").getScore()+1 );
40. 
    
41. 
    
42. }
43. @EventHandler
44. public void onPearl(PlayerInteractEvent event){
45. Player player = event.getPlayer();
46. if(event.getAction()== Action.RIGHT_CLICK_AIR ||event.getAction()== Action.RIGHT_CLICK_BLOCK){
47. if (player.getItemInHand().getType()== Material.ENDER_PEARL){
48. Scoreboard board = event.getPlayer().getScoreboard();
49. Objective objective = board.getObjective ( "pearl");
50. 
    
51. objective.getScore(ChatColor.AQUA+"Pearls:").setScore(objective.getScore(ChatColor.AQUA+"Pearls:").getScore()+1 );
52. 
    
53. 
    
54. 
    
55. }
56. 
    
57. }
58. }
59. 
    
60. 
    
61. 
    
62. }

Make sure the PlayerInteractEvent is even firing in the first place. I would add (priority = EventPriority.LOWEST, ignoreCancelled=true) to the top of your onPearl method. That should fix it.

Format your code.. and if you "do not possess any extensive knowledge" I suggest you learn java before you work with the bukkit api.
