Minecraft Java插件 - 块位置是相同的，但它仍然无法工作

Question

任何能够回答此问题的人。我正在配置中存储信标位置。当信标被破坏时，我得到了正在破坏的块的位置，并检查它是否等于我的配置中的那个。我不知道为什么它不起作用，我甚至做了p.sendmessage并将这两个值作为一条消息发送，并且它们是完全相同的......

            p.sendMessage("§9§lPillars " + dot + " §7You can only break blocks placed by a player!");
        }
    }
}

在命令中设置信标位置：

if (args[0].equalsIgnoreCase("yellowbeacon1")) {
    getConfig().set("yellowbeacon1.world", w);
    getConfig().set("yellowbeacon1.x", x - 0.5);
    getConfig().set("yellowbeacon1.y", y);
    getConfig().set("yellowbeacon1.z", z - 0.5);
    saveConfig();

    p.sendMessage("§9§lPillars " + dot + " §7Successfully set §eyellow §5beacon1!");
}

^^我为每个灯塔都这样做。

我希望你理解我的问题。

可能不会导致您遇到的问题，但在比较Location类实例时，请使用equals方法而不是==，因为它们绝对不是当您在同一方法中创建其中一个比较位置时的相同实例。

与您的问题没有密切关系，但稍微重构您的代码。如果你必须复制粘贴一些东西，它标记为你可以提取的方法。因此，使用签名Location getLocation(World world, String beaconprefix)创建方法，该方法从配置中获取块位置并创建它，从而显着减少代码长度。

private Location getLocation(World world, String beaconPrefix) {
  double x = getConfig().getDouble(beaconPrefix + ".x");
  double y = getConfig().getDouble(beaconPrefix + ".y");
  double z = getConfig().getDouble(beaconPrefix + ".z");
  return new Location(world, x, y, z);
}
