我怎样才能培育出定制的暴徒呢？

Question

我正试图从我的类中派生出一个实体，该实体自定义EntityZombie。

World bukkit; // ...
CraftWorld craft = (CraftWorld)bukkit;
net.minecraft.server.v1_7_R3.World world = craft.getHandle();
Boss boss = new Boss(world);
Location spawn; // ...
boss.setLocation(spawn.getX(), spawn.getY(), spawn.getZ(), spawn.getYaw(), spawn.getPitch());
world.addEntity(boss);

public class Boss extends EntityZombie {
    public Boss(World world) {
        super(world);
    }
    // Empty right now, nothing more than the normal zombie
}

产出如下：

• 如果我不去运行上面的代码，当我回来的时候，我什么也看不见。
• 如果我靠得很近，客户端就会崩溃。

与控制台无关，这是完整的崩溃报告。

也许，我需要先为每一个生物群登记一下吗？如果是，怎么做？

您可以从: RemoteEntities Api下载这里

如果需要，可以下载其他自定义的暴徒api，但我建议您使用它。
