Actions on Google: Number Genie Sample

⚠️ Warning: Conversational Actions will be deprecated on June 13, 2023. For more information, see Conversational Actions Sunset.

This sample demonstrates Actions on Google features for use on Google Assistant, including how to steer conversation in a numeric guessing game through the use of localization (French and English), deep links, fallbacks, contexts, alongside rich responses -- using the Node.js client library and deployed on Cloud Functions for Firebase.

This Action uses the i18n-node library to provide responses in both French and English, which are listed in the locales directory. In each function execution, the strings.js setLocale() function is called to set the i18n-node locale based on the user locale in the incoming request. Prompts are then selected by i18n-node from the available languages, defaulting to en if the user's language is unavailable.

⚠️ This code sample was built using Dialogflow. We now recommend using Actions Builder or the Actions SDK to develop, test, and deploy Conversational Actions.

Setup Instructions

Prerequisites

Node.js and NPM
- We recommend installing using NVM
Install the Firebase CLI
- We recommend using version 6.5.0, npm install -g [email protected]
- Run firebase login with your Google account

Configuration

Actions Console

From the Actions on Google Console, New project (this will become your Project ID) > Create project > under More options > Conversational
From the top menu under Develop > Actions (left nav) > Add your first action > BUILD (this will bring you to the Dialogflow console) > Select language and time zone > CREATE.
In the Dialogflow console, go to Settings ⚙ > Export and Import > Restore from zip using the agent.zip in this sample's directory.

Firebase Deployment

On your local machine, in the functions directory, run npm install
Run firebase deploy --project {PROJECT_ID} to deploy the function
- To find your Project ID: In Dialogflow console under Settings ⚙ > General tab > Project ID.

Dialogflow Console

Return to the Dialogflow Console > select Fulfillment > Enable Webhook > Set URL to the Function URL that was returned after the deploy command > SAVE.
```
Function URL (dialogflowFirebaseFulfillment): https://${REGION}-${PROJECT_ID}.cloudfunctions.net/dialogflowFirebaseFulfillment
```
From the left navigation menu, click Integrations > Integration Settings under Google Assistant > Enable Auto-preview changes > Test to open the Actions on Google simulator then say or type Talk to my test app.

Running this Sample

You can test your Action on any Google Assistant-enabled device on which the Assistant is signed into the same account used to create this project. Just say or type, “OK Google, talk to my test app”.
You can also use the Actions on Google Console simulator to test most features and preview on-device behavior.

Error deploying on Firebase

When I try to send the command firebase deploy the CLI give me ann error

npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! [email protected] lint: eslint --fix "**/*.js"`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] lint script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

What is this?

input.welcome intent not handled

I imported the project into an app on firebase, deployed it and tried to test it. The default intent I get is input.welcome and I don't see any handler for that in the code. I'm thinking that should be there as that is the intent which starts the game. Am I missing something ?
Handled intents are
const Actions = {
GENERATE_ANSWER: 'generate_answer',
CHECK_GUESS: 'check_guess',
QUIT: 'quit',
PLAY_AGAIN_YES: 'play_again_yes',
PLAY_AGAIN_NO: 'play_again_no',
DEFAULT_FALLBACK: 'input.unknown',
UNKNOWN_DEEPLINK: 'deeplink.unknown',
NUMBER_DEEPLINK: 'deeplink.number',
DONE_YES: 'done_yes',
DONE_NO: 'done_no',
REPEAT: 'repeat'
};

Cannot see number genie nodejs working on simulator.

I followed all the steps mentioned in readme file and successfully able to import the actions and deploy the node on firebase. When I goto the simulator to check then I get default response and get the following error on Google actions simulator:

"message": "Webhook error (206)"

On DialogFlow simulator, in the diagnostic report I see following error in the fulfillment response:

{
  "error": "Converting circular structure to JSON"
}

How I can use this code without google functions, I use Heroku?

I want to run this example without use google functions. I am beginning with nodejs, can you help me?

getRandomPrompt alternates first two elements from array vs. picking random element from array

After the first prompt, getRandomPrompt alternates between the first two elements of the array vs. picking a random element that is not the last prompt.

The code below demonstrates the issue:
https://repl.it/ISpe/2

// Utility function to pick prompts
function getRandomPrompt (app, array) {
  let lastPrompt = app.data.lastPrompt;
  let prompt;
  if (lastPrompt) {
    for (let index in array) {
      prompt = array[index];
      if (prompt != lastPrompt) {
        break;
      }
    }
  } else {
    prompt = array[Math.floor(Math.random() * (array.length))];
  }
  return prompt;
}

// Utility function to pick prompts
function getRandomPrompt_updated (app, array) {
  let lastPrompt = app.data.lastPrompt;
  let filteredArray = array.filter(x => x != lastPrompt)
  return filteredArray[Math.floor(Math.random() * (filteredArray.length))];
}


var app = { data: { }};
const HIGHER_PROMPTS = ['You\'re getting warm. It\'s higher than %s. Have another guess?',
    'Warmer. It\'s also higher than %s. Take another guess.', 'It\'s so close, but it\'s higher than %s.'];
    
console.log("=====Current method=====");
for(let i = 0;i < 20;i++) {
  app.data.lastPrompt = getRandomPrompt(app, HIGHER_PROMPTS);
  console.log(app.data.lastPrompt);
}
console.log("=====Updated method=====");
app = { data: { }};
for(let i = 0;i < 20;i++) {
  app.data.lastPrompt = getRandomPrompt_updated(app, HIGHER_PROMPTS);
  console.log(app.data.lastPrompt);
}
