我正在尝试为中心服务器创建一个插件来切换可见性。像Hypixel，或任何其他具有集线器的半流行服务器。

右键点击游戏中的粘液球时，它会变为正确的项目，然后立即变回。如果你想在游戏中看到它，请加入我的测试服务器，因为我可能没有正确描述它。

对于那些对Spigot API有什么困惑的人来说，它适用于Minecraft。如果你能提供我搞乱的代码行，以及如何改变它，那就太好了。谢谢！

发生的事情是你在代码中切换粘液球然后在你要切换它的下一行。

此：

    if (p.getItemInHand().getType().equals(Material.NETHER_STAR)) {
        p.performCommand("star");

    }

    if (p.getItemInHand().getType().equals(Material.SLIME_BALL)) {
        p.getInventory().setItem(slot, visibility3);

    }

    if (p.getItemInHand().getType().equals(Material.FIREBALL)) {
        p.getInventory().setItem(slot, visibility);

    }

应改为：

    if (p.getItemInHand().getType().equals(Material.NETHER_STAR)) {
        p.performCommand("star");

    }else if (p.getItemInHand().getType().equals(Material.SLIME_BALL)) {
        p.getInventory().setItem(slot, visibility3);

    }else if (p.getItemInHand().getType().equals(Material.FIREBALL)) {
        p.getInventory().setItem(slot, visibility);

    }

基本上你将粘液球改为火球，下一段代码会将火球改回泥球。添加else语句使得如果项目被更改，它将不会检查if语句中的其余项目。希望有意义！
