The NPE is because you never initialize this: static ArrayList<String> tenKillsLore; You could probaby just change it to this and it'll work fine: static ArrayList<String> tenKillsLore = new ArrayList<String>();
I think I found another NPE. "Stats." + p.getUniqueId().toString() + ".Achievements." + s)) { Code (Text): static boolean isUnlocked(Player p, boolean s) { if (dm.getData().getBoolean( "Stats." + p.getUniqueId().toString() + ".Achievements." + s)) { return true; } else return false; }
@gigosaurus Thanks, It's fixed! However I still have a small problem: Code (Text): static boolean isUnlocked(Player p, boolean s) { if (dm.getData().getBoolean( "Stats." + p.getUniqueId().toString() + ".Achievements." + s)) { return true; } else return false; } This isn't working, and is always passing as false, even though the YML is set to true?
After Achievements you check a boolean --> Stats.0000-0000(etc).Achievements.true: true Might want to check the achievement.
You already checked if it was unlocked back in the setLores method. Change "if (isUnlocked(p, s)) {" in addLores to "if (s) {"
