AdvancementAPI

AdvancementAPI is library made to easily create Advancement for your server using built in Bukkit/Spigot API features.

Example

Creating root advancement unlocked by collecting 3 cobblestone

public class CobblestoneAdvancement implements AdvancementCreator {

    public static final String ID = "some_cobblestone";
    
    @Override
    public @NotNull Advancement create(@NotNull Context context) {
        
        Advancement advancement = new Advancement(context.getPlugin(), ID);

        advancement.setDisplay(x -> {
            x.setTitle("Some Cobblestone");
            x.setDescription("Get 3 cobblestone");
            x.setBackground(BackgroundType.STONE);
            x.setIcon(Material.COBBLESTONE);
        });

        advancement.addCriteria("cobblestone", TriggerType.INVENTORY_CHANGED, trigger -> {
            trigger.hasItemMatching(item -> {
                item.setType(Material.COBBLESTONE);
                item.setCount(3);
            });
        });
        
        return advancement;
    }

}

Creating child advancement of previous one unlocked by crafting a stone pickaxe

public class StonePickaxeAdvancement implements AdvancementCreator {

    public static final String ID = "stone_pickaxe";

    @Override
    public @NotNull Advancement create(@NotNull Context context) {

        Advancement advancement = new Advancement(context.getPlugin(), ID);

        advancement.setParent(new NamespacedKey(context.getPlugin(), CobblestoneAdvancement.ID));

        advancement.setDisplay(x -> {
            x.setTitle("Stone Pickaxe");
            x.setDescription("Craft a stone pickaxe with your 3 cobblestone");
            x.setIcon(Material.STONE_PICKAXE);
        });

        advancement.addCriteria("pickaxe", TriggerType.INVENTORY_CHANGED, trigger -> {
            trigger.hasItem(Material.STONE_PICKAXE);
        });

        return advancement;
    }

}

Register previously created advancements

public class MyPlugin extends JavaPlugin {

    private final AdvancementManager manager = new AdvancementManager(this);

    @Override
    public void onEnable() {
        manager.register(new CobblestoneAdvancement());
        manager.register(new StonePickaxeAdvancement());
        
        manager.createAll();
    }
