Useful Global Functions in streaming ui( No-Iframe) Solution

Sending data to unreal app:

CODE

var jsonToSendToUnreal={"cmd":"run","room":"dining room"}

e3ds_controller.sendToUnreal(jsonToSendToUnreal)

Receiving data to unreal app:

CODE

e3ds_controller.callbacks.onResponseFromUnreal = function (descriptor) {
  //descriptor could be a json object
    console.log("ob-onResponseFromUnreal");
    console.log("UnrealResponse: " + descriptor);
    document.getElementById('LatencyStats').innerHTML = descriptor;
}

Useful global event:
These functions will be called from the core library if they are defined in global scope. If you dont define them than they will not be called . So make sure your have deifned them in proper execution order.
Inside functions, required operation can be done for the functionality of the web app.

CODE

e3ds_controller.callbacks.onDataChannelOpen = function () {
    console.log("ob-onDataChannelOpen");
}

e3ds_controller.callbacks.onDataChannelClose = function () {
    console.log("ob-onDataChannelClose");
}

e3ds_controller.callbacks.onConfigAcquire = function () {
    console.log("ob-onConfigAcquire");
}

e3ds_controller.callbacks.onSessionExpired = function () {
    self.location = "assets/pages/session-expired.htm";
}


e3ds_controller.callbacks.onReceivingAppAcquiringProgress = function (percent) {
    console.log("onReceivingAppAcquiringProgress: " + percent);
}


e3ds_controller.callbacks.onReceivingAppPreparationProgress = function (percent) {
    console.log("onReceivingAppPreparationProgress: " + percent);
}

e3ds_controller.callbacks.onReceivingAppStartingProgress = function (percent) {
    console.log("onReceivingAppStartingProgress: " + percent);
}

e3ds_controller.callbacks.onHtmlBind = function () {
    console.log("ob-onHtmlBind");
}

e3ds_controller.terminate()

Explanations of above events:
onConfigAcquire : called when configuration data arrives
onDataChannelOpen: called when communication channel between the browser and UE app is established
onDataChannelClose: called when communication channel between the browser and UE app is broken
onSessionExpired: called when stream session time expires
onHtmlBind: when the system finishes binding function to existing stick Ui elements

terminate(): Stops the stream by stopping the connection to the app.
