其他的常用对象 客户端相关触发事件（Event）： 我们与系统沟通是用lua语言、系统能识别的API以及事件 Lua语言是一种沟通工具 API是系统告诉我们它会什么 Event是他回答我们的方式 比如说红外线警铃这种 你走过去了，触发到了机关，整个系统就会发出警报，人家就知道有人入侵了。同理，触发事件就是这个道理，告诉我们发生了什么事，这样我们就能做出一些反应。还是拿上面的比喻。事件不止是告诉我们有人入侵，同时也告诉我们入侵者的姓名、年龄、样貌等东西，存在一些临时的变量里面发送给我们，而这些变量就是所谓的触发事件变量，arg0~arg9 触发事件可以看做为系统与函数之间的高级互动，虽然我们有共同的语言，但是语言之中的沟通却是风马牛各不相及，各种偏离。比如说我们想写一个插件：队友死亡时喊话，我们写出了一个判断队友死亡的函数，可是系统并不知道在队友死亡的时候要调用这个函数。于是，只好通过无限循环来达到目的，这样做无疑是给系统增加额外的负担。所以，触发事件的作用便体现在它会在队友死亡的时候发出一个通知，而我们将判断函数绑定到这个通知上。如此，在队友死亡的时候便能喊出话来。通常事件在响应时，会向相应的函数传递一些事件相关的信息，这些信息存在叫arg0～arg9的变量里，我们可以直接在事件响应函数中访问到它们。 以下是由globaleventhandle.lua中提取出来的触发事件列表，可能翻译有些出入，具体以lua中的功能为准。 |

- 1、春天，山坡的朝阳处雪开始融化，慢慢地露出黄黑色的地皮；雪水滋润着泥土，浸湿了去年的草楂；被雪盖着过了冬眠的草根苏醒复活了，渐渐地倔强有力地推去陈旧的草楂烂叶，奋力地生长起来。与此同时，去年秋天随风摇落下来的草木种子，也被湿土裹住，在孳殖着根须，争取它们的生命。山的背阴处虽然还寒气凛凛，可是寒冷的威力已在渐渐衰弱。朝阳处的温暖雪水顺着斜谷流过来，融化了硬硬的雪层，开始冲开山涧溪水的冰面。巨大的冻 ...

- 每到春天，红得如火的木棉花，粉得如霞的芍药花，白得如玉的月季花竞相开放。它们有的花蕾满枝，有的含苞初绽，有的昂首怒放。一阵阵沁人心肺的花香引来了许许多多的小蜜蜂，嗡嗡嗡地边歌边舞。 <br><br>盼望着，盼望着，（表现急切喜悦的心情）东风来了，春天的脚步近了。 <br><br>清晨,春姑娘穿着美丽的衣裳,舞着暖风,招展地笑着向我们走来,给大自然披上了新装,使万物显现出无限生机.一缕缕金黄色的阳光撒向刚披上新装的草地,阳 ...
