这个代码，我们都没有测试过，看起来，是直接在脚本中来发送操作码信息
总体说来，我觉得还是比较有研究价值的关于变态魔兽世界私服的一些脚本代码。

* GUID 700000 (this must be different to all your other vendors)
* Displays the moneybag icon in the gossip list
* Displays the text "Look at all the weapons I have" in the gossip list
*
* The second line creates an instance of the ItemList object named items1.
* We pass it a reference to the vendor we created before. The class does the rest.
*
* The third and fourth lines are examples of adding items to our item list (named items_1).
* You can give an item an extended_cost by passing a second parameter to the function.
* This script does not support time-limited or respawning items
*
* The final line is the most important. This line adds your vendor to the internal list of vendors that will be processed by the script.

具体的就不多说了，因为我也没有测试过，有兴趣的朋友可以去测试测试，本代码支持T端
