Properties

• duration : int

Detailed Description

You can't create one of these elements directly, but several other elements inherit the methods and properties of these elements.

There are several predefined enumerations and constants provided in this class:

1. Duration This enum describes the possible predefined duration types. Generally a specific value in milliseconds can be supplied instead of one of these values.

• Feedback.Infinite - Infinite effect duration

2. State This enum describes the state of the effect. An effect will be in one of these states.

• Feedback.Stopped - The effect is not running. This is the initial state.
• Feedback.Paused - The effect is paused.
• Feedback.Running - The effect is running.
• Feedback.Loading - The effect is loading.

3. ErrorType This enum describes the possible errors happening on the effect.

• Feedback.UnknownError - An unknown error occurred.
• Feedback.DeviceBusy - The feedback could not start because the device is busy, the device could be busy if a higher-priority client is using the haptics/actuator device.
