Working with Triggers

Like all game syncs, a Trigger is a Wwise element that is called by the game and then defines a specific response in Wwise to accommodate what is happening in the game. More specifically, a Trigger responds to a spontaneous occurrence in the game and launches a Stinger. The Stinger, which is a brief musical phrase that is superimposed and mixed over the currently playing music, is a musical reaction to the game. For more information about how Triggers and Stingers work together, see Using Stingers.

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.

The following illustration demonstrates the Trigger mechanism that plays a Stinger at a key point in the game.

In Wwise Authoring, Triggers are represented by this icon: .

Creating Triggers

You can create Triggers in the Game Syncs tab of the Project Explorer.

To create a new Trigger:

  1. In the Project Explorer, switch to the Game Syncs tab.

  2. In the Triggers section, do one of the following:

    • Select a Work Unit or Virtual Folder and in the Project Explorer toolbar click Create new 'Trigger'.

    • Right-click a Work Unit or Virtual Folder and select New Child > Trigger from the shortcut menu.

  3. Replace the default name with one that best represents the Trigger.


    Each Trigger name must be unique and consist of only letters, digits, and underscores. Use either a letter or underscore as the first character.

Deleting Triggers

Keep in mind that if you delete a Trigger that is assigned to a Stinger, the association with the Music Segment for the Stinger is removed.

To delete Triggers:

  1. In the Project Explorer, switch to the Game Syncs tab.

  2. In the Triggers section, select the Triggers you want to delete and do either of the following:

    • Press the Delete key.

    • Right-click and select Delete from the shortcut menu.
