基于Java的Minecraft游戏后端自定义插件 05事件监听器

内容简介

事件监听器

文档中org.bukkit.event都是事件包






https://www.youtube.com/watch?v=PWQNsqwD-AY.


public void registerEvents(Listener listener, Plugin plugin) {
以上省略…
for (Map.Entry, Set> entry : plugin.getPluginLoader().createRegisteredListeners(listener, plugin).entrySet()) {
getEventListeners(getRegistrationClass((Class)entry.getKey())).registerAll((Collection)entry.getValue());
}
}

那么我们可以从上边的代码发现, BukkitAPI 先对传入的 Listener 实现类进行检查,
之后反射遍历传入的 Listener 实现类的所有方法, 之后再做些必要的事情后就注册好了一个事件了

插件中我编写的事件监听包括游戏进入游戏后的操作提示以及图鉴界面上的按钮点击操作跳转：

如何实现VexView绘制的Gui界面中VexButton的点击完成相应的操作如界面跳转？
通过赋予VexView绘制的Gui界面中相同功能的VexButton以相同的ButtonID，通过ButtonClickEvent中的getButtonID（）；方法获取每一个按钮的ID并赋予其所需要的方法，当监听到玩家点击了某个Button时，获取其ID并调用其方法如VexViewAPI.openGui（）方法以实现界面跳转或其他功能。
