2D with Voice Chat and Indicator

The Hierarchy

This scene is the same as our main 2D scene. The only new object in the Hierarchy is the 'Voice Manager' GameObject.

Voice Manager

The Voice manager is an empty GameObject with three Photon components added to it.

The first is the 'Photon Voice Network' component. Most of the properties are self explanatory. You'll want to change all the log levels to 'ERROR', or it will flood the console. This component is the main "brains" behind voice chat.

If adding from scratch, usually the only two things you need to change is changing the log mode to 'ERROR' and setting the 'Primary Recorder'. You'll just drag and drop the 'Recorder' component into this slot (which we will talk about next).

Recorder

This component controls when, how, and who. You'll want to make sure 'transmit enabled' is checked. It is not by default. If you want a push-to-talk system, this is the property you would set 'true' for transmit, and 'false' for not transmit.

Drag and drop this Recorder component into the 'Primary Recorder' on the 'Photon Voice Network' component (the demo scene should already be set up this way).

Make sure 'Transmit Enabled' is checked, or no sound will be transmitted. You can create logic to modify this property of you want a 'mute' button, or set up push-to-talk.

Audio Changes Handler

This component is useful to handle audio device and config changes.

Where's the Logic?

In the 2D Voice demo scene, all the logic is on the player. The player is located in the resources folder and is called PlayerPrefabForMultiplayer_2D_w_Voice.

The Player

The Player Prefab differs a bit from the other 2D Player prefab. In the hierarchy we've added two new GameObjects.

'Speaker' and 'Indicator' are what makes this 2D Player different from the other 2D scene.

The 'Speaker' is an empty GameObject. Position it where you want the positional audio of the player speaking to come from. When you add the 'Speaker' component, the 'Audio Source' component will be added automatically..

The 'Indicator' is a sprite to display above the player's head when audio is detected from their mic and transmitted over the network.

On the Player parent GameObject, we've added a new component. It is a 'Photon Voice View'. Next we will talk about the new FSM we used to create the Voice Indicator above the player's head. In that FSM, we are getting properties from this component.

The 'isRecording Indicator' FSM (Located on the Player)

This is a very simple FSM that gets the 'isRecording' bool from the 'Photon Voice View'. It then uses that bool to set the 'enabled' property of the sprite renderer on the 'Indicator'.
