Each Dialogue Event contains a set of rules that reflects the different conditions and outcomes that exist within your game. 这些规则是用 State Group（状态组）和 State（状态）来定义的。When you add a State Group to a Dialogue Event, the corresponding states are also added.
To add State Groups to a Dialogue Event:
Load a Dialogue Event into the Dialogue Event Editor.
在 Project Explorer 中，切换至 Game Syncs 选项卡。
In the State Groups section, select one or more State Groups that you want to add to the Dialogue Event.
将状态组拖至 Dialogue Event Editor 的 State Groups 窗格。
这些状态组和相应的状态就显示在 Dialogue Event Editor 中了。
