Trigger（触发器）是一种 Wwise 元素，跟其他 Game Sync（游戏同步器）一样会被游戏调用。触发器会定义 Wwise 将做出怎样的特定响应来反映游戏中的情节变化。More specifically, a Trigger responds to a spontaneous occurrence in the game and launches a Stinger. Stinger 是一种短乐句，它会与当前音乐叠加并混合播放，以音乐的形式来对游戏做出响应。For more information about how Triggers and Stingers work together, see 使用 Stinger.
For example, in a fighting game, when a character lands a powerful kick, you can intensify the impact of that action with a Stinger. Before you create a Stinger, you must create a Trigger, perhaps named High kick, to be called at these points in the game, and you must choose a short Music Segment to associate with the Trigger.
下图展示了游戏关键时刻用来播放 Stinger 的 Trigger 机制。

备注 Each Trigger name must be unique and consist of only letters, digits, and underscores. 只有字母或下划线可以作为首字符。
