godot-enet-voip 🎙️🌐

logo

it's just a simple branch of the original project, change the network platform to enet and solved the growing buffer issue with community help and some weird solution.

godot-voip is a Godot Engine addon which makes it very easy to setup a real-time voice-chat system in your Godot game. This addon also includes a demo project.

Engine Compatibility

  • 2.0: Godot Engine 3.2
  • 3.0+: Godot Engine 3.3+

Setup

Adding to a existing project

(Any kind of high-level multiplayer peer is required.)

  1. Click on the AssetLib inside editor or go to the Godot Asset Library to download the latest release, or you can clone/download this repository to get the latest commit.
  2. Select the addons/godot-voip folder and move it into your Godot project. (Note: make sure the structure is still res://addons/godot-voip)
  3. Go to project-settings/audio and enable audio input.
  4. Now go to the plugins tab also inside project-settings and enable the godot-voip plugin.
  5. Add either a VoiceInstance (one connection) or a VoiceOrchestrator (more than 2 participants) node to your scene.
  6. Set $VoiceInstance.recording or $VoiceOrchestrator.recording to true and it will send your microphone input to connected participants.

Running demo
