Bukkit Player check achievements - bukkit

Question

I don't know what I should put into player.getAdvancementProgress(Here).
if (player.getAdvancementProgress().isDone()) {
}
Maybe someone knows something?

Answer 1

You should use an Advancement object, specially the advancement that you are looking for informations.
You can get it with Bukkit.getAdvancement(NamespacedKey.fromString("advancement/name")) where advancement/name can be nether/all_potions for example. You can get all here (column: "Resource location). If you are getting it from command, I suggest you to add tab complete.
Example of TAB that show only not-done success :
#Override
public List<String> onTabComplete(CommandSender sender, Command cmd, String label, String[] arg) {
List<String> list = new ArrayList<>();
if(!(sender instanceof Player))
return list;
Player p = (Player) sender;
String prefix = arg[arg.length - 1].toLowerCase(Locale.ROOT); // the begin of the searched advancement
Bukkit.advancementIterator().forEachRemaining((a) -> {
AdvancementProgress ap = p.getAdvancementProgress(a);
if((prefix.isEmpty() || a.getKey().getKey().toLowerCase().startsWith(prefix)) && !ap.isDone() && !a.getKey().getKey().startsWith("recipes"))
list.add(a.getKey().getKey());
});
return list;
}
Then, in the command you can do like that:
#Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] arg) {
if(!(sender instanceof Player)) // not allowed for no-player
return false;
Player p = (Player) sender;
// firstly: try to get advancement
Advancement a = Bukkit.getAdvancement(NamespacedKey.fromString(arg[0]));
if(a == null)
a = Bukkit.getAdvancement(NamespacedKey.minecraft(arg[0]));
if(a == null) // can't find it
p.sendMessage(ChatColor.RED + "Failed to find success " + arg[0]);
else { // founded :
AdvancementProgress ap = p.getAdvancementProgress(a);
p.sendMessage(ChatColor.GREEN + "Achivement " + a.getKey().getKey() + " stay: " + ChatColor.YELLOW + String.join(", ", ap.getRemainingCriteria().stream().map(this::getCleaned).collect(Collectors.toList())));
}
return false;
}
private String getCleaned(String s) { // this method is only to make content easier to read
String[] args = s.split("/");
return args[args.length - 1].replace(".png", "").replace(".jpg", "").replace("minecraft:", "").replace("_", " ");
}
Else, if you want to get all advancements, you should use Bukkit.advancementIterator().
