Crea Loader del Materiale

You can create your own MaterialLoader. A material loader will allow you to create an ItemStack from the configuration.

Example with HeadDatabase:

package fr.maxlego08.menu.loader.materials;

import fr.maxlego08.menu.api.loader.MaterialLoader;
import me.arcaniax.hdb.api.HeadDatabaseAPI;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.inventory.ItemStack;

public class HeadDatabaseLoader implements MaterialLoader {

    @Override
    public String getKey() {
        return "hdb";
    }

    @Override
    public ItemStack load(YamlConfiguration configuration, String path, String materialString) {

        try {

            HeadDatabaseAPI api = new HeadDatabaseAPI();
            return api.getItemHead(materialString);

        } catch (Exception exception) {
            exception.printStackTrace();
        }

        return null;
    }
}
