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;
}

public class StonePickaxeAdvancement implements AdvancementCreator {
public static final String ID = "stone_pickaxe";
@Override
public @NotNull Advancement create(@NotNull Context context) {
