Solved Scoreboard Help! Edit Scoreboard in new method

I've solved this, don't see a delete post button though.

I'm trying to set-up a scoreboard that when a player gets a kill it add's one to their Score and when they die removes one.

I have the scoreboard set-up and can see it but I'm unsure how to add/remove points when the player dies/kills.

Scoreboard Code:

Code:java

ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
 
Objective score = board.registerNewObjective("points", "dummy");
score.setDisplaySlot(DisplaySlot.SIDEBAR);
score.setDisplayName(ChatColor.AQUA + "" + ChatColor.BOLD + "Score");
 
for(Player player : Bukkit.getOnlinePlayers()){
 
player.setScoreboard(board);
 
Score playerScore = score.getScore(player);
playerScore.setScore(1);
int newScore = playerScore.getScore() - 1;
playerScore.setScore(newScore);
 
}

I know how to set it up for calling the method when the player gets killed or kills but am unsure how to edit the scoreboard in those methods.

All help appreciated
