Triggers

You can use triggers to set up interactive elements in your sequence. You can create different types of trigger that respond to different types of user action. When a trigger is activated, it can add one or more objects to the environment.

For example, you could create a button trigger that adds an interactive coffee cup IFX to the sequence. When a user plays back your sequence, they can press the button to spawn their own coffee cup. You could also use audio IFX to play audio in response to a user's actions, or use a Special Function IFX to jump to another part of the timeline.

The sections below provide general information about triggers. For more information about a specific type of trigger, see the following sections:

Trigger effect options

For instructions on how to access effect options, see Effect options. All trigger objects include options for Triggered Effects. This is where you configure what will happen when the trigger is activated.

All trigger objects also have a Trigger For option.

  • Select Trigger For to toggle between Everyone and Local User.

If you select Everyone, all users in the Session where the sequence plays will experience the triggered effect. For example, all users will see a 3D model or hear a sound that the trigger adds to the environment. If you select Local User, only the user that activates the trigger experiences the triggered effect.

Adding a triggered effect

To add a triggered effect, complete the following steps:

  1. On the Current Effect Options page, select NEW.

  2. Select the type of effect that you want to add.

  3. Select the effect to add.

  4. Place the object in the environment.

Modifying a triggered effect

By default, triggered effects are not visible in the environment. For people that view your sequence, they become visible when the trigger is activated. However, if you want to modify a triggered effect in the Content Editor, select the corresponding cog on the Current Effect Options page.

After you select the cog icon, the triggered effect becomes visible in the environment. You can access the Move or Gizmo controls through the object menu to adjust the object's position, scale, or rotation.

The Current Effect Options page updates to show the effect options for the triggered effect. For more information, see the following section.

Modifying a triggered effect's options

To access effect options for a triggered effect, first access the effect options for the trigger. Then, select the cog icon for the triggered effect that you want to modify, as described above.

The majority of the options match those described in Common effect options. However, there are two additional options, as described in the following table.

OptionDescription

Length

The length of time that the triggered effect will remain in the environment. Note: The default Length for a triggered effect is 30 seconds. However, if you choose a recording for the triggered effect, the Length value is initially set to the length of the recording.

Spawn Type

The number of instances of the triggered effect that can be active at the same time. If you choose Once, the trigger will create one instance of the effect. A user can’t activate the trigger to create a new instance until the previous instance is removed from the environment. To control how long each instance is in the environment, see the Length option.

If you choose Multiple, the trigger will create a new instance of the effect each time that a user activates the trigger.
