1. Setting up default actions

1. Inside Streamer.bot, navigate to the Actions tab.
2. Right click on the Actions tab and select Add.
3. Create a group for the action called Minecraft Websocket.
4. Name the action MC WS Connected.
5. Then press Ok.
6. Add 2 more actions to the group, called MC WS Disconnected and MC WS Message.

2. Connecting to the WebSocket Server

1. Inside Streamer.bot, navigate to the Servers/Clients tab.
2. Click the sub-tab Websocket Clients.
3. Inside the window, add a new Host, by right-clicking and pressing Add.
4. Inside the popup window, set the Name to Minecraft WebSocket Server.
5. Inside the popup window, set the Host to ws://{localhost}:{8887}. (please replace {localhost} with your host, and {8887} with your port number)
6. Set the Action Connected to MC WS Connected.
7. Set the Action Disconnected to MC WS Disconnected.
8. Set the Action Message to MC WS Message.
9. Click Ok.

3. Setting up Actions

In this guide, the following will be the flowchart of the actions:

Example workflow:

WS Connect

• Log to file

WS Message

• Authenticate
• Subscribe to events
• Send events to WS Events

WS Disconnect

• Log to file

WS Events

• Get event ran
• Convert event data to Json, and store in variable
• Run WS Event-{event ran}

WS Event-{events}

• Send message in twitch chat

1. MC WS Connected

1. Make a sub action File->Write to file, make a new file called WS_Logs.txt, and set it to append to the file, with the text %date% %time% - WS Connected.

2. MC WS Disconnected

1. Make a sub action File->Write to file, select the file called WS_Logs.txt, and set it to append to the file, with the text %date% %time% - WS Disconnected.

3. MC WS Message

This is where the magic starts!

1. Make a sub action File->Write to file, select the file called WS_Logs.txt, and set it to append to the file, with the text %date% %time% - WS Message: %message%.
2. Make a sub action C#->Run C# code
   • inside the C# window, add the following inside Execute():

var auth = ""; // Add your authentication token here
string[] listeners = { // Add the events you want to listen to here
  "PlayerDeathEvent",
  "PlayerJoinEvent",
  "PlayerQuitEvent",
  "PlayerChatEvent",
  "PlayerDamageEvent",
  "PlayerHealEvent" ,
  "PlayerAdvancementDoneEvent",
  "PlayerChangedWorldEvent",
  "PlayerFoodChangeEvent",
  "PlayerDamagePlayerEvent"
};

var msg = args["message"].ToString();

if (msg.StartsWith("Authentication needed")) {
  // Send authentication message
  CPH.WebsocketSend("Bearer " + auth);
  return true;
}
if (msg.StartsWith("Authentication not required") || msg.StartsWith("Successfully Authenticated")) {
  // Subscribe to events
  var listenString = "Listen " + String.Join("\nListen ", listeners);
  CPH.WebsocketSend(listenString);
  return true;
}

if (msg.StartsWith("Event ")) {
  // Event received
  CPH.SetArgument("event", msg.Substring("Event ".Length));
  CPH.RunAction("MC WS Event Handler");
}
return true;

3. This will handle all messages between the server and the client.

4. MC WS Event Handler

1. Make a sub action C#->Run C# code
   • inside the C# window, add the following inside Execute():

// Add these at the top of your code
// using Newtonsoft.Json;
// using System.Collections.Generic;

var ev = args["event"].ToString();
var evRun = ev.Split(' ')[0];
var unParsedJson = ev.Substring(evRun.Length);
List<object> json = JsonConvert.DeserializeObject<List<object>>(unParsedJson);
CPH.SetArgument("event-json", json);
CPH.RunAction("MC WS Event-" + evRun);
return true;

2. This will forward the event to the correct action.

5. MC WS Event-{event ran}

1. Replace {event ran} with the event name you want to handle.
2. Handle the event
3. Example with PlayerDeathEvent: (making the action name MC WS Event-PlayerDeathEvent)

// Add this at the top of your code
// using System.Collections.Generic;

List<object> json = args["event-json"];
string player = json[0].ToString();
string deathMessage = json[1].ToString();
CPH.SendMessage(deathMessage);
return true;

Forwarding Twitch Chat to Minecraft Chat

1. Inside Streamer.bot, navigate to the Actions tab.
2. Make an action called Forward Twitch Chat to Minecraft Chat.
3. Navigate to the Settings->Events tab.
4. Set Chat Message to Forward Twitch Chat to Minecraft Chat.
5. Go back to the Forward Twitch Chat to Minecraft Chat action.
6. Make a sub action C#->Run C# code
   • inside the C# window, add the following inside Execute():

var msg = args["message"].ToString();
// Make sure to remove bad characters from the message, if you don't, users can break out of tellraw, and other commands
msg = msg.Replace("\\", "");
msg = msg.Replace("\"", "");

var user = args["user"].ToString();

CPH.WebsocketSend("Command say ["+user+"] " + msg);
return true;

7. This will forward the message to the Minecraft server.
