In our 0.2.6 SDK release we’ve added the runtime instance to all callbacks, stream fit options for web, and general bugfixes and improvements.

Breaking Changes

All SDKs must be updated so that they include these changes.

  • [Rainway Services] Added mandatory headers to identify response payload types.

Runtime callbacks

Based on feedback, we’ve added the active RainwayRuntime instance as the first parameter to all RainwayConfig callbacks. We think this will allow developers to simplify their logic when accessing the instance.

RainwayRuntime.initialize({
    // This callback notifies you when a remote peer wishes to connect to this peer.
    onConnectionRequest: (
        runtime: RainwayRuntime,
        request: RainwayConnectionRequest
    ) => {
        console.log(
            `The peerId of the local runtime is ${runtime.getPeerId()}`
        );
    },
});

Stream Fit Options

In the Web SDK, we’ve added the ability to adjust how App-Isolated streams are sized. In the past, the stream size would always match the streamed application window dimensions. Now, that behavior is configurable using RainwayStreamFit.

RainwayRuntime.initialize({
    // This callback notifies you when a new peer-to-peer connection is initiated, or when it's connectivity state changes
    onPeerStateChange: async (runtime, peer, state) => {
        if (state == RainwayPeerState.New) {
            // request a stream for the newly connected peer
            const stream = await peer.requestStream(InputLevel.Keyboard);

            // ensure that the stream is always sized to match the full desktop
            stream.setStreamFit(RainwayStreamFit.FullDesktop);
        }
    },
});

Bug Fixes and Improvements

  • [Native SDKs] Improved Gamepad driver installation logic to handle additional edge cases.
  • [Web SDK] Added a RainwayPeer.send method to automatically encode and send UTF-8 strings.
  • [Web SDK] Added RainwayPeer.disconnected to indicate when a peer is in a disconnected state.
  • [Web SDK] Refactored RainwayPeer.state type to better represent all peer states.
  • [Node.js SDK] Corrected the built-in DLL path so developers need not use RAINWAYSDK_DLL_PATH.
  • [Node.js SDK] Fixed an issue with streaming when isolateProcessIds was missing that led to no video.
  • [Node.js SDK] Fixed an issue with programatically accessing connected peers that led to a crash.
  • Added InputLevel.All to all SDKs, to simplify granting peers access to all input methods.
