Question

我正在尝试制作一个插件。这个插件会在玩家的第一次加入时为其提供一个特殊的cookie，这样他们就可以点击它并查看他们在知识中的点击次数。我知道，这听起来没用，但我会加入它。它当前不起作用，并且控制台中没有错误。当我尝试右键单击使用它时，它什么都不做。请帮忙。我是Java的新手。

Answer 1

这是因为您没有在@EventHandler方法之上使用onPlayerUse。它应该是这样的：

@EventHandler
public void onPlayerUse(PlayerInteractEvent event){
    //code here
}

请记住，所有活动都需要@EventHandler面前

如果上述答案无效，是否忘记添加 plugin.yml 文件？

如果您没有添加此plugin.yml文件，服务器将无法识别您的插件。

要做到这一点，您只需右键点击“src＆＃39;并选择新的＆＃39;然后＆＃39;文件＆＃39;。作为名称，添加＆＃39; plugin.yml＆＃39; 。打开＆＃39; plugin.yml＆＃39;在Eclipse中使用此文件作为＆＃39; plugin.yml＆＃39;格式：

main: me.<yourname>.<pluginname>.<classname>
name: <plugin name> 
version: <version number>
author: <your name> 

commands: 
    <command name>:
        description: <description here>

既然你声称自己是新的＆＃39;对Java来说，我认为这可能是问题所在。
