Speaker

The Patchwork Speaker (SPK) device outputs audio generated from other Patchwork devices. The Patchwork Speaker is the end of the chain that results in audio.

Ther Patchwork Speaker is meant to work with other Patchwork devices only. This speaker will not play sound cues.

The Patchwork Speaker accepts audio input, then plays the sound that players can hear.

You can set up multiple speakers on an island and have each play different sounds. This will let you mix your audio by adjusting the relative volume of each speaker, without he need to travel back to the source audio devices.

Device Options

Other Device Options

In Create mode, walk up to the device and press E to open the Customize panel. Some device options mirror the controls you can manipulate with the Patchwork tool. They are present so that you can use the event binding system to trigger changes to how those controls behave, although you can choose to change them here instead of using the knobs. The Allow Cable Access option can only be modified using the Customize panel.

VFX Preview

The VFX preview for the Patchwork Speaker shows:

• The motion of the VFX preview shows the soundwave pattern being played by the Speaker.

• The width of the VFX preview indicates the volume setting of the Speaker.

Direct Event Binding

Following are the direct event binding options for this device.

Functions

A function listens for an event on a device then performs an action.

1. For any function, click the option, then Select Device to access and select from the Device dropdown menu.

2. Once you've selected a device, click Select Event and select the event that triggers this function.

3. If more than one device or event triggers a function, press the Add button to add a line and repeat these steps.

Events

Direct event binding uses events as transmitters. An event tells another device to perform a function.

1. For any event option, click the option, then Select Device to access and select from the Device dropdown menu.

2. Once you've selected a device, click Select Function to bind the event to a function for that device.

3. If more than one function is triggered by the event, press the Add button and repeat.

Using Speaker in Verse

You can use the code below to control a Speaker device in Verse. This code uses all features of the Speaker device API. Modify it to fit the needs of your experience.

using { /Fortnite.com/Devices }

using { /Verse.org/Simulation }

using { /UnrealEngine.com/Temporary/Diagnostics }

# A Verse-authored creative device that can be placed in a level

speaker_example := class(creative_device):

    @editable

    Speaker:patchwork_speaker_device = patchwork_speaker_device{}

    # Runs when the device is started in a running game

    OnBegin<override>()<suspends>:void=

        

        Sleep(5.0)

        Speaker.Disable()

        Print("Device Disabled")

        Sleep(5.0)

        Speaker.Enable()

        Print("Device Enabled")

To use this code in your UEFN experience, follow these steps.

1. Drag a Speaker device onto your island.

2. Create a new Verse device named speaker_example. To learn how to create a new device in Verse, see Create Your Own Device Using Verse.

3. Open Verse Explorer and double-click speaker_example.verse to open the script in Visual Studio Code.

4. Paste in the code above, compile, and drag the Verse-authored device onto your island.

5. Select your Verse device in the Outliner.

6. In the device’s Details panel, assign the object reference for the Speaker to the Speakert device on your island. You can use the eyedropper to pick the device in the viewport, or use the dropdown and search for the device.

7. Save your project and click Launch Session.
